COMMENTARY ON SECTION I OF THE KDIGOTRANSPLANT GUIDELINEIMMUNOSUPPRESSION

DIGORecommendations inChapter 1nduction Therapy

11 We recommend starting a combination of immu-nosuppressive medications before or at the timeof kidney transplantation (1A)

12 We recommend including induction therapy witha biologic agent as part of the initial immunosup-pressive regimen in KTRs (1A)121 We recommend that an IL2-RA [interleu-

kin-2 receptor antagonist] be the firstlineinduction therapy (1B)

122 We suggest using a lymphocyte-depletingagent rather than an IL2-RA for KTRs athigh immunologic risk (2B)

DOQIRationale andCommentary

It clearly is important to start immunosuppres-ion before or at the time of transplant Inductionherapy with a biologic agent such as interleukin

(IL-2) receptor antagonists or thymoglobulinecreases the frequency of acute rejection andow is used in up to 80 of US transplantenters However individual US transplant cen-ers determine immunosuppression protocolsased on their particular patient population or-an source experience ease of use and cost ofherapy Ethnic diversity of the population andhe number of high-risk patients vary in differentegions of the United States which explains inart variations in protocols used in differententers Applicability of the recommended

DIGO guidelines in this section must be inter- n

reted with these differences in mind The lastublished survey of immunosuppression use inS transplant centers was in the 2006 Organrocurement and Transplantation NetworkScien-

ific Registry of Transplant Recipients (OPTNRTR) Annual Report6 and reported on the usef calcineurin inhibitors (CNIs) mycophenolatecid compounds (MPA) mammalian target ofapamycin (mTOR) inhibitors and inductionherapy (Box 1)

Guidelines for induction therapy will be mostelevant not to community nephrologists but tohose working in transplant centers in whichnduction is used Not all patients need inductionherapy The cost of induction therapy is substan-ial and should be viewed in the context ofiskbenefit for a particular donorrecipient pro-le In the United States the use of lymphocyte-epleting antibodies (thymoglobulin and alemtuz-mab) for induction is increasing6 Many centersill use these agents in low-risk patients toinimize exposure to other maintenance drugs

DIGORecommendations inChapter 2 InitialndMaintenance Immunosuppressiveedications

21 We recommend using a combination of immuno-suppressive medications as maintenance therapyincluding a CNI and an antiproliferative agentwith or without corticosteroids (1B)

22 We suggest that tacrolimus be the first-line CNIused (2A)221 We suggest that tacrolimus or CsA be

started before or at the time of transplanta-tion rather than delayed until the onset ofgraft function (2D tacrolimus 2B CsA)

23 We suggest that mycophenolate be the first-lineantiproliferative agent (2B)

24 We suggest that in patients who are at low immuno-logical risk and who receive induction therapycorticosteroids could be discontinued during thefirst week after transplantation (2B)

25 We recommend that if mTOR inhibitors areused they should not be started until graftfunction is established and surgical wounds arehealed (1B)

DOQIRationale andCommentary

Initial Immunosuppression

We agree that optimum initial maintenanceherapy includes a CNI and an antiproliferativegent and that tacrolimus is the preferred CNI forost patients The Symphony Study a largeulticenter clinical trial showed that the combi-

ation of low-dose tacrolimus mycophenolateofetil (MMF) and steroids with daclizumab

nduction provided superior efficacy without theegative impact on renal function compared withither cyclosporine or a CNI-free regimen ofow-dose sirolimus78 However in a small num-er of patients other issues such as age ethnic-ty risk of new-onset diabetes mellitus and pre-ious toxicity with tacrolimus may result in thenitial use of cyclosporine Immediate CNI useas not been shown to cause a delay in renalecovery Although many centers briefly hold orodify the CNI dose in the setting of delayed

raft function especially when using antilympho-yte-depleting induction agents treatment withhese drugs should be initiated before or at theime of discharge from the hospital and not

ithheld because of delayed graft function As m

tated mycophenolate compounds (MMF andycophenolate sodium) are used as the initial

ntiproliferative agent of choice in most USransplant centers

SteroidTherapyDiscontinuation

Steroid sparing with discontinuation withinhe first few weeks after transplant has gainedidespread acceptance in the United States withore than 25 of patients being discharged after

ransplant off steroid therapy6 Although theDOQI work group agreed that steroid therapy

ould be discontinued in low-risk patients afternduction therapy we did not think that thisuggestion should be accepted as a universaluideline for several reasons Although short-nd medium-term results in corticosteroid therapyiscontinuation protocols show equivalent pa-ient and graft survival there may be a price toay in the long term Acute rejection rates areigher in well-designed randomized clinical tri-ls of steroid withdrawal In addition the pres-nce of chronic interstitial fibrosis and tubulartrophy may be greater in corticosteroid-freeatients portending decreased long-term graftunction The heterogeneity of the US donor andecipient population may have a role in thisssue Newer transplant regimens decrease pred-isone dosage to 5 mgd Apart from less boneisease the potential metabolic benefits of corti-osteroid-free protocols versus 5 mgd seem toe less significant What is clear is that discontinu-tion of steroid therapy early after transplanteems to be associated with less risk of rejectionhan discontinuation of steroids later (1 year)t should be noted that there are no studies ofifferent times in the first year to determine whenorticosteroid therapy can be discontinued safelyn some centers steroid therapy discontinuations accomplished up to 6 months posttransplantate discontinuation of steroid therapy (1 yearosttransplant) is no longer recommended andorms the basis of KDIGO guideline 25 withhich we agree It also must be emphasized that

teroid therapy withdrawal should be performednly when there is close frequent monitoring ofhe patient

ncreased rejection rate with early use of theseompounds in place of CNIs The Symphonytudy showed that the highest rejection rateccurred in the arm using low-dose sirolimusith MMF and steroids78

DIGORecommendations inChapter 3ong-termMaintenance Immunosuppressiveedications

31 We suggest using the lowest planned doses ofmaintenance immunosuppressive medications by2-4 months after transplantation if there has beenno acute rejection (2C)

32 We suggest that CNIs be continued rather thanwithdrawn (2B)

32 If prednisone is being used beyond the first weekafter transplantation we suggest prednisone becontinued rather than withdrawn (2C)

DOQIRationale andCommentary

Decreasing ImmunosuppressiveDosage

Although our work group agreed with sugges-ion 31 we stress that dosing of immunosuppres-ion should at all times take into account thendividual patientrsquos risk profile balancing rejec-ion with the adverse effects of medications Inome patients this may mean higher drug dosingrug levels to account for a higher risk of rejec-ion Although most US transplant centers nowtrive for a lower dose of immunosuppressiveedication after the early posttransplant period

he transplant center should define each patientrsquosarget drug dosing based on immunologic riskhich depends on ethnicity age history of previ-us transplant and level of HLA antibodies

ContinueorWithdrawCNITherapy

Although we agreed that mTOR inhibitorshould not be used in the early posttransplanteriod78 newer clinical trials have exploredwitching from CNIs to mTOR inhibitors 3-6onths posttransplant910 Early results suggest

elative safety with improvement in renal func-ion Whether the trade-off of less nephrotoxic-ty with a different side-effect profile of mTORnhibitors will be beneficial in the long termemains to be determined The work groupelieved that suggestion 32 to continue CNI

herapy indefinitely in all patients required

ore study before it could be accepted as auideline

SteroidTherapyWithdrawal

We agree that late steroid therapy with-rawal (1 year) is inadvisable but stress thathe definition of ldquoearlyrdquo steroid discontinua-ion has not been well defined and may occurfter the first week (see commentary underhapter 2)

DIGORecommendations inChapter 4trategies toReduceDrugCosts

41 If drug costs block access to transplantation astrategy to minimize drug costs is appropriateeven if use of inferior drugs is necessary to obtainthe improved survival and quality of life benefitsof transplantation compared with dialysis (NotGraded)411 We suggest strategies that may reduce drug

costs includebull limiting use of a biologic agent for

induction to patients who are high-riskfor acute rejection (2C)

bull using ketoconazole to minimize CNIdose (2D)

bull using a nondihydropyridine CCB to mini-mize CNI dose (2C)

bull using azathioprine rather than mycophe-nolate (2B)

bull using adequately tested bioequivalent ge-neric drugs (2C)

bull using prednisone long-term (2C)

42 Do not use generic compounds that have not beencertified by an independent regulatory agency tomeet each of the following criteria when comparedto the reference compound (Not Graded)bull contains the same active ingredientbull is identical in strength dosage form and route of

administrationbull has the same use indicationsbull is bioequivalent in appropriate bioavailability

studiesbull meets the same batch requirements for identity

strength purity and qualitybull is manufactured under strict standards

43 It is important that the patient and the clinicianresponsible for the patientrsquos care be made aware ofany change in a prescribed immunosuppressivedrug including a change to a generic drug (NotGraded)

44 After switching to a generic medication that ismonitored using blood levels obtain levels andadjust the dose as often as necessary until a stable

therapeutic target is achieved (Not Graded)

DOQIRationale andCommentary

Drug costs are becoming an increasing issue inransplantation that impacts on patient adherencend ultimately affects graft survival Currently im-unosuppressive drugs in the United States are

overed by the Centers for Medicare amp Medicaidervices (CMS) the primary insurer for manyTRs for 3 years after transplant although legisla-

ion is being considered to continue this coverageor the life of the kidney Most KTRs are usingany other medications in addition to immunosup-

ressive drugs In general the transplant commu-ity (patients health care providers and policyakers) need to embrace the concept of cost con-

ainment and the risk(s) to the patient and graft byhese measures However this needs to be balancedy who benefits and how much risk is at stake

Use of drugs that block the cytochrome P-450A system in an attempt to decrease CNIosing and costs are rarely used in the Unitedtates The concern is that inadvertent cessa-

ion of treatment with these drugs causing aignificant decrease in drug levels could resultn an acute rejection episode Therefore theork group did not think that many of the 411

uggestions should be accepted as a guidelinewitching from a mycophenolate compound ton azathioprine compound in the later posttrans-lant period may be considered in some pa-ients as another cost-saving maneuver espe-ially in view of recent US registry datahowing similar long-term survival with theserugs11 Although we agree with the sugges-ions outlined in 42 it should be recognizedhat many generic formulations have nevereen tested in transplant patients Patient con-usion with medications when a different ge-eric formulation or even different strengths ofhe same drug from different manufacturers isispensed at each refill can lead to inadvertentedication errors possibly affecting out-

omes Patient education is crucial to avoidrrors in medication administration We agreeith recommendation 44 that it is crucial toonitor patients after an immunosuppressive

osage change brand change or change to aeneric drug However it needs to be recog-ized that implementation of this guideline canecome burdensome as practices become inun-

ated with inquiries from patients payors and 5

harmacies regarding medications Transplantenters and practices that see many transplantatients bear an inordinate part of this burden

DIGORecommendations inChapter 5onitoring ImmunosuppressiveMedications

51 We recommend measuring CNI blood levels(1B) and suggest measuring at leastbull every other day during the immediate postopera-

tive period until target levels are reached (2C)bull whenever there is a change in medication or

patient status that may affect blood levels (2C)bull whenever there is a decline in kidney function that

may indicate nephrotoxicity or rejection (2C)511 We suggest monitoring CsA using 12-h

trough (C0) 2-h post-dose (C2) or abbrevi-ated AUC (2D)

512 We suggest monitoring tacrolimus using12-h trough (C0) (2C)

52 We suggest monitoring MMF levels (2D)53 We suggest monitoring mTOR inhibitor levels (2C)

DOQIRationale andCommentary

Because immunosuppressive drugs are classi-ed as narrow therapeutic agents drug-levelonitoring is a necessary tool to maximize effi-

iency and minimize toxicity The blood drugevel is not synonymous with level of immuno-uppression but may correlate imperfectly withhis effect In most US transplant centers levelsf CNI and mTOR inhibitors are monitoredPA monitoring is problematic because of the

oor correlation between trough levels and areander the curve (AUC) exposure Optimal moni-oring of MPA requires a 4- to 6-hour abbrevi-ted AUC measurement which is logisticallyifficult in the outpatient setting Although stud-es show that monitoring MPA levels in the earlyosttransplant period may be helpful in cyclospor-ne-treated patients recent evidence suggests thatuch monitoring may be less important in pa-ients on tacrolimus therapy12 With most USTRs now being started on tacrolimus as theNI of choice MPA monitoring is not routine inany US transplant centers Although one per-

on in our work group believed there may still beome value in monitoring MPA levels the otherembers questioned the value and applicability

f this practice (KDIGO suggestion 52) Cur-ently many US centers measure MPA only inhe setting of possible drug-related toxicities oride effects Although we agree with suggestion

DIGORecommendations inChapter 6reatment ofAcuteRejection

61 We recommend biopsy before treating acuterejection unless the biopsy will substantiallydelay treatment (1C)

62 We suggest treating subclinical and borderline acuterejection (2D)

63 We recommend corticosteroids for the initialtreatment of acute cellular rejection (1D)631 We suggest adding or restoring maintenance

prednisone in patients not on steroids whohave a rejection episode (2D)

632 We suggest using lymphocyte-depleting anti-bodies or OKT3 [muromonab-CD3] for acutecellular rejections that do not respond tocorticosteroids and for recurrent acute cellu-lar rejections (2C)

64 We suggest treating antibody-mediated acute rejec-tion with one or more of the following alternativeswith or without corticosteroids (2C)bull plasma exchangebull intravenous immunoglobulinbull anti-CD20 antibodybull lymphocyte-depleting antibody

65 For patients who have a rejection episode wesuggest adding mycophenolate if the patient is notreceiving mycophenolate or azathioprine or switch-ing azathioprine to mycophenolate (2D)

DOQIRationale andCommentary

We concur that biopsies should be performed onll KTRs suspected of having an acute rejectionrecommendation 61) Expert interpretation of theiopsy specimen by pathologists accustomed toeading kidney transplant biopsies is as importants expertise in performing the biopsy It is contro-ersial whether subclinical and borderline rejec-ions should be treated (recommendation 62 sup-orted by low evidence [2D]) Subclinical rejectionsre diagnosed in patients who have protocol biop-ies performed by design not for deterioration inidney function Recent data suggest that the riskf subclinical rejection in patients on tacrolimusnd mycophenolate compound therapy is so lowhat protocol biopsies may no longer be indi-ated13 Whether this is true in patients with highmmunologic risk or patients on minimization pro-ocols (ie steroid-free protocols or lower CNI doses)s uncertain Whether borderline rejection shoulde treated or some infiltrates may be protective also

s uncertain In most US centers steroids are used d

ost frequently as first-line treatment for acuteejection followed by lymphocyte-depleting anti-odies in steroid-resistant rejection but there maye exceptions to this approach Decision makingegarding appropriate initial treatment for acuteejection should be based on clinical and patho-ogic information Timing of the rejection episodeosttransplant type of induction agent used beforeejection degree of deterioration in kidney functiont the time of rejection and histologic grade of theejection may influence selection of the appropriatenitial antirejection therapy There is increasingecognition of the role of antibody-mediated mecha-isms in acute rejection This process requirespecial blood tests (to detect donor-specific antibod-es) and histochemical stains (immunofluorescenceor C4d) for diagnosis14 Coordination with theransplant center is critical to ensure that all appro-riate testing is performed and specific treatment isnitiated After treatment of an acute episode opti-

izing overall immunosuppression is requiredonsiderations should include changing the CNIdding a mycophenolate compound or increasinghe dose adding corticosteroids to previously ste-oid-free regimens or addingsubstituting an mTORnhibitor More than 85 of patients are alreadysing MPA agents so the number available forwitching will be relatively small

DIGORecommendations inChapter 7reatment of ChronicAllograft Injury (CAI)

71 We recommend kidney allograft biopsy for allpatients with declining kidney function of unclearcause to detect potentially reversible causes (1C)

72 For patients with CAI and histological evidence ofCNI toxicity we suggest reducing withdrawing orreplacing the CNI (2C)721 For patients with CAI eGFR 40 mLmin

173 m2 and urine total protein excretion500 mgg creatinine (or equivalent protein-uria by other measures) we suggest replac-ing the CNI with a mTOR inhibitor (2D)

empts at decreasing the dosage have failed Onelso must ensure that all other causes of CAI arexcluded to avoid inappropriate drug adjustmentsr missed treatment options Although our workroup thought that KDIGO suggestion 721 maye reasonable in some patients we also want tomphasize that the role of mTOR inhibitors in thereatment of CAICNI toxicity is poorly defined Its clear that switching from a CNI to an mTORnhibitor should be avoided in patients with se-erely decreased glomerular filtration rate (GFR)ndor the presence of proteinuria however the exactuidelines for when to switch are still evolving

Biopsy

Renal allograft biopsy is the gold standard foriagnosing the cause of a change in renal allo-raft function It is useful in all clinical situationsescribed in KDIGO suggestions 91-94 Poten-ial causes of allograft dysfunction include vol-me depletion compromised renal blood flowrinary outflow obstruction parenchymal causesuch as acute rejection (cellular andor humoral)hronic allograft nephropathy recurrent or deovo disease or BK nephropathy Patients show-ng a 20-25 increase in creatinine level aboveaseline values warrant consideration for biopsyther indications for pursuing renal allograftiopsy would be a less-than-expected responseo treatment of acute rejection The expectedesponse would be dependent on the severity ofissue injury noted on the diagnostic biopsy speci-

en Delayed graft function lasting longer than-7 days warrants biopsy with repeated biopsieserformed every 7-10 days until graft functionecovers New-onset proteinuria protein 20g creatinine or 20 g24 h also merits aidney biopsy De novo and recurrent glomerulariseases are common causes of new-onset pro-einuria Patients with de novo or recurrent glo-erular diseases should be followed up closely

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

2532 We recommend that adult male KTRs beinformed of the possible risks of infertilityfrom mTORi (1C)25321 We suggest that adult male KTRs

who wish to maintain fertility shouldconsider avoiding mTORi or bank-ing sperm prior to mTORi use (2C)

SexualDysfunction

Sexual dysfunction is a topic often over-ooked in clinic visits but one that manyatients want addressed Sexual dysfunctionas been reported in 30-60 of KTRs8586

he use of 5-phosphodiesterase inhibitors tomprove male erectile dysfunction appears toe safe in KTRs Although KDIGO recommen-ations 2511 and 2512 are not graded ourDOQI work group concurred with these rec-

ion Until further data emerge regarding the safety ofTOR inhibitors in pregnancy this precaution must

e weighed against the risks and inconvenience ofhanging immunosuppression therapy All pregnantTRs are considered high-risk pregnancies and shoulde followed up by a high-risk obstetric team

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

COMMENTARY ON SECTION I OF THE KDIGOTRANSPLANT GUIDELINEIMMUNOSUPPRESSION

DIGORecommendations inChapter 1nduction Therapy

11 We recommend starting a combination of immu-nosuppressive medications before or at the timeof kidney transplantation (1A)

12 We recommend including induction therapy witha biologic agent as part of the initial immunosup-pressive regimen in KTRs (1A)121 We recommend that an IL2-RA [interleu-

kin-2 receptor antagonist] be the firstlineinduction therapy (1B)

122 We suggest using a lymphocyte-depletingagent rather than an IL2-RA for KTRs athigh immunologic risk (2B)

DOQIRationale andCommentary

It clearly is important to start immunosuppres-ion before or at the time of transplant Inductionherapy with a biologic agent such as interleukin

(IL-2) receptor antagonists or thymoglobulinecreases the frequency of acute rejection andow is used in up to 80 of US transplantenters However individual US transplant cen-ers determine immunosuppression protocolsased on their particular patient population or-an source experience ease of use and cost ofherapy Ethnic diversity of the population andhe number of high-risk patients vary in differentegions of the United States which explains inart variations in protocols used in differententers Applicability of the recommended

DIGO guidelines in this section must be inter- n

reted with these differences in mind The lastublished survey of immunosuppression use inS transplant centers was in the 2006 Organrocurement and Transplantation NetworkScien-

ific Registry of Transplant Recipients (OPTNRTR) Annual Report6 and reported on the usef calcineurin inhibitors (CNIs) mycophenolatecid compounds (MPA) mammalian target ofapamycin (mTOR) inhibitors and inductionherapy (Box 1)

Guidelines for induction therapy will be mostelevant not to community nephrologists but tohose working in transplant centers in whichnduction is used Not all patients need inductionherapy The cost of induction therapy is substan-ial and should be viewed in the context ofiskbenefit for a particular donorrecipient pro-le In the United States the use of lymphocyte-epleting antibodies (thymoglobulin and alemtuz-mab) for induction is increasing6 Many centersill use these agents in low-risk patients toinimize exposure to other maintenance drugs

DIGORecommendations inChapter 2 InitialndMaintenance Immunosuppressiveedications

21 We recommend using a combination of immuno-suppressive medications as maintenance therapyincluding a CNI and an antiproliferative agentwith or without corticosteroids (1B)

22 We suggest that tacrolimus be the first-line CNIused (2A)221 We suggest that tacrolimus or CsA be

started before or at the time of transplanta-tion rather than delayed until the onset ofgraft function (2D tacrolimus 2B CsA)

23 We suggest that mycophenolate be the first-lineantiproliferative agent (2B)

24 We suggest that in patients who are at low immuno-logical risk and who receive induction therapycorticosteroids could be discontinued during thefirst week after transplantation (2B)

25 We recommend that if mTOR inhibitors areused they should not be started until graftfunction is established and surgical wounds arehealed (1B)

DOQIRationale andCommentary

Initial Immunosuppression

We agree that optimum initial maintenanceherapy includes a CNI and an antiproliferativegent and that tacrolimus is the preferred CNI forost patients The Symphony Study a largeulticenter clinical trial showed that the combi-

ation of low-dose tacrolimus mycophenolateofetil (MMF) and steroids with daclizumab

nduction provided superior efficacy without theegative impact on renal function compared withither cyclosporine or a CNI-free regimen ofow-dose sirolimus78 However in a small num-er of patients other issues such as age ethnic-ty risk of new-onset diabetes mellitus and pre-ious toxicity with tacrolimus may result in thenitial use of cyclosporine Immediate CNI useas not been shown to cause a delay in renalecovery Although many centers briefly hold orodify the CNI dose in the setting of delayed

raft function especially when using antilympho-yte-depleting induction agents treatment withhese drugs should be initiated before or at theime of discharge from the hospital and not

ithheld because of delayed graft function As m

tated mycophenolate compounds (MMF andycophenolate sodium) are used as the initial

ntiproliferative agent of choice in most USransplant centers

SteroidTherapyDiscontinuation

Steroid sparing with discontinuation withinhe first few weeks after transplant has gainedidespread acceptance in the United States withore than 25 of patients being discharged after

ransplant off steroid therapy6 Although theDOQI work group agreed that steroid therapy

ould be discontinued in low-risk patients afternduction therapy we did not think that thisuggestion should be accepted as a universaluideline for several reasons Although short-nd medium-term results in corticosteroid therapyiscontinuation protocols show equivalent pa-ient and graft survival there may be a price toay in the long term Acute rejection rates areigher in well-designed randomized clinical tri-ls of steroid withdrawal In addition the pres-nce of chronic interstitial fibrosis and tubulartrophy may be greater in corticosteroid-freeatients portending decreased long-term graftunction The heterogeneity of the US donor andecipient population may have a role in thisssue Newer transplant regimens decrease pred-isone dosage to 5 mgd Apart from less boneisease the potential metabolic benefits of corti-osteroid-free protocols versus 5 mgd seem toe less significant What is clear is that discontinu-tion of steroid therapy early after transplanteems to be associated with less risk of rejectionhan discontinuation of steroids later (1 year)t should be noted that there are no studies ofifferent times in the first year to determine whenorticosteroid therapy can be discontinued safelyn some centers steroid therapy discontinuations accomplished up to 6 months posttransplantate discontinuation of steroid therapy (1 yearosttransplant) is no longer recommended andorms the basis of KDIGO guideline 25 withhich we agree It also must be emphasized that

teroid therapy withdrawal should be performednly when there is close frequent monitoring ofhe patient

32 If prednisone is being used beyond the first weekafter transplantation we suggest prednisone becontinued rather than withdrawn (2C)

DOQIRationale andCommentary

Decreasing ImmunosuppressiveDosage

Although our work group agreed with sugges-ion 31 we stress that dosing of immunosuppres-ion should at all times take into account thendividual patientrsquos risk profile balancing rejec-ion with the adverse effects of medications Inome patients this may mean higher drug dosingrug levels to account for a higher risk of rejec-ion Although most US transplant centers nowtrive for a lower dose of immunosuppressiveedication after the early posttransplant period

he transplant center should define each patientrsquosarget drug dosing based on immunologic riskhich depends on ethnicity age history of previ-us transplant and level of HLA antibodies

ContinueorWithdrawCNITherapy

Although we agreed that mTOR inhibitorshould not be used in the early posttransplanteriod78 newer clinical trials have exploredwitching from CNIs to mTOR inhibitors 3-6onths posttransplant910 Early results suggest

elative safety with improvement in renal func-ion Whether the trade-off of less nephrotoxic-ty with a different side-effect profile of mTORnhibitors will be beneficial in the long termemains to be determined The work groupelieved that suggestion 32 to continue CNI

SteroidTherapyWithdrawal

We agree that late steroid therapy with-rawal (1 year) is inadvisable but stress thathe definition of ldquoearlyrdquo steroid discontinua-ion has not been well defined and may occurfter the first week (see commentary underhapter 2)

DOQIRationale andCommentary

Drug costs are becoming an increasing issue inransplantation that impacts on patient adherencend ultimately affects graft survival Currently im-unosuppressive drugs in the United States are

overed by the Centers for Medicare amp Medicaidervices (CMS) the primary insurer for manyTRs for 3 years after transplant although legisla-

ion is being considered to continue this coverageor the life of the kidney Most KTRs are usingany other medications in addition to immunosup-

ressive drugs In general the transplant commu-ity (patients health care providers and policyakers) need to embrace the concept of cost con-

ainment and the risk(s) to the patient and graft byhese measures However this needs to be balancedy who benefits and how much risk is at stake

Use of drugs that block the cytochrome P-450A system in an attempt to decrease CNIosing and costs are rarely used in the Unitedtates The concern is that inadvertent cessa-

ion of treatment with these drugs causing aignificant decrease in drug levels could resultn an acute rejection episode Therefore theork group did not think that many of the 411

uggestions should be accepted as a guidelinewitching from a mycophenolate compound ton azathioprine compound in the later posttrans-lant period may be considered in some pa-ients as another cost-saving maneuver espe-ially in view of recent US registry datahowing similar long-term survival with theserugs11 Although we agree with the sugges-ions outlined in 42 it should be recognizedhat many generic formulations have nevereen tested in transplant patients Patient con-usion with medications when a different ge-eric formulation or even different strengths ofhe same drug from different manufacturers isispensed at each refill can lead to inadvertentedication errors possibly affecting out-

omes Patient education is crucial to avoidrrors in medication administration We agreeith recommendation 44 that it is crucial toonitor patients after an immunosuppressive

osage change brand change or change to aeneric drug However it needs to be recog-ized that implementation of this guideline canecome burdensome as practices become inun-

ated with inquiries from patients payors and 5

harmacies regarding medications Transplantenters and practices that see many transplantatients bear an inordinate part of this burden

DIGORecommendations inChapter 5onitoring ImmunosuppressiveMedications

51 We recommend measuring CNI blood levels(1B) and suggest measuring at leastbull every other day during the immediate postopera-

tive period until target levels are reached (2C)bull whenever there is a change in medication or

patient status that may affect blood levels (2C)bull whenever there is a decline in kidney function that

may indicate nephrotoxicity or rejection (2C)511 We suggest monitoring CsA using 12-h

trough (C0) 2-h post-dose (C2) or abbrevi-ated AUC (2D)

512 We suggest monitoring tacrolimus using12-h trough (C0) (2C)

52 We suggest monitoring MMF levels (2D)53 We suggest monitoring mTOR inhibitor levels (2C)

DOQIRationale andCommentary

Because immunosuppressive drugs are classi-ed as narrow therapeutic agents drug-levelonitoring is a necessary tool to maximize effi-

iency and minimize toxicity The blood drugevel is not synonymous with level of immuno-uppression but may correlate imperfectly withhis effect In most US transplant centers levelsf CNI and mTOR inhibitors are monitoredPA monitoring is problematic because of the

oor correlation between trough levels and areander the curve (AUC) exposure Optimal moni-oring of MPA requires a 4- to 6-hour abbrevi-ted AUC measurement which is logisticallyifficult in the outpatient setting Although stud-es show that monitoring MPA levels in the earlyosttransplant period may be helpful in cyclospor-ne-treated patients recent evidence suggests thatuch monitoring may be less important in pa-ients on tacrolimus therapy12 With most USTRs now being started on tacrolimus as theNI of choice MPA monitoring is not routine inany US transplant centers Although one per-

on in our work group believed there may still beome value in monitoring MPA levels the otherembers questioned the value and applicability

f this practice (KDIGO suggestion 52) Cur-ently many US centers measure MPA only inhe setting of possible drug-related toxicities oride effects Although we agree with suggestion

Renal allograft biopsy is the gold standard foriagnosing the cause of a change in renal allo-raft function It is useful in all clinical situationsescribed in KDIGO suggestions 91-94 Poten-ial causes of allograft dysfunction include vol-me depletion compromised renal blood flowrinary outflow obstruction parenchymal causesuch as acute rejection (cellular andor humoral)hronic allograft nephropathy recurrent or deovo disease or BK nephropathy Patients show-ng a 20-25 increase in creatinine level aboveaseline values warrant consideration for biopsyther indications for pursuing renal allograftiopsy would be a less-than-expected responseo treatment of acute rejection The expectedesponse would be dependent on the severity ofissue injury noted on the diagnostic biopsy speci-

en Delayed graft function lasting longer than-7 days warrants biopsy with repeated biopsieserformed every 7-10 days until graft functionecovers New-onset proteinuria protein 20g creatinine or 20 g24 h also merits aidney biopsy De novo and recurrent glomerulariseases are common causes of new-onset pro-einuria Patients with de novo or recurrent glo-erular diseases should be followed up closely

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

gree with the KDIGO work group that thera-eutic lifestyle measures should be encour-ged Data regarding steroid therapy with-rawal and weight gain are controversial Aecent double-blind randomized controlled trialxamining early steroid therapy withdrawalid not show a difference in weight gain at 5ears posttransplant compared with the cohortemaining on standard maintenance corticoste-oid therapy62

DIGORecommendations inChapter 17ardiovascularManagement

171 Consider managing CVD at least as intensively inKTRs as in the general population with appropri-ate diagnostic tests and treatments (Not Graded)

172 We suggest using aspirin (65-100 mgd) in allpatients with atherosclerotic CVD unless there arecontraindications (2B)

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

his clearly deserves more attention becauseontrol of CVD has the potential to contributeore to long-term kidney graft survival than the

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

186 We suggest that patients with a history of skincancer be offered treatment with oral acitretin ifthere are no contraindications (2B)

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

There is a limited scientific basis for KDIGOuggestion recommendation 186 Although reti-oids now are used routinely in KTRs with aigh skin cancer burden our KDOQI work groupelieves that more data are needed before this

DOQIRationale andCommentary

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

exacerbated by immunosuppressionbull The therapies available for the can-

tions interfere with ability to admin-ister the standard chemotherapy

202 For patients with Kaposi sarcoma we suggestusing mTORi along with a reduction in overallimmunosuppression (2C)

DOQIRationale andCommentary

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

COMMENTARY ON SECTION I OF THE KDIGOTRANSPLANT GUIDELINEIMMUNOSUPPRESSION

DIGORecommendations inChapter 1nduction Therapy

11 We recommend starting a combination of immu-nosuppressive medications before or at the timeof kidney transplantation (1A)

12 We recommend including induction therapy witha biologic agent as part of the initial immunosup-pressive regimen in KTRs (1A)121 We recommend that an IL2-RA [interleu-

kin-2 receptor antagonist] be the firstlineinduction therapy (1B)

122 We suggest using a lymphocyte-depletingagent rather than an IL2-RA for KTRs athigh immunologic risk (2B)

DOQIRationale andCommentary

It clearly is important to start immunosuppres-ion before or at the time of transplant Inductionherapy with a biologic agent such as interleukin

(IL-2) receptor antagonists or thymoglobulinecreases the frequency of acute rejection andow is used in up to 80 of US transplantenters However individual US transplant cen-ers determine immunosuppression protocolsased on their particular patient population or-an source experience ease of use and cost ofherapy Ethnic diversity of the population andhe number of high-risk patients vary in differentegions of the United States which explains inart variations in protocols used in differententers Applicability of the recommended

DIGO guidelines in this section must be inter- n

reted with these differences in mind The lastublished survey of immunosuppression use inS transplant centers was in the 2006 Organrocurement and Transplantation NetworkScien-

ific Registry of Transplant Recipients (OPTNRTR) Annual Report6 and reported on the usef calcineurin inhibitors (CNIs) mycophenolatecid compounds (MPA) mammalian target ofapamycin (mTOR) inhibitors and inductionherapy (Box 1)

Guidelines for induction therapy will be mostelevant not to community nephrologists but tohose working in transplant centers in whichnduction is used Not all patients need inductionherapy The cost of induction therapy is substan-ial and should be viewed in the context ofiskbenefit for a particular donorrecipient pro-le In the United States the use of lymphocyte-epleting antibodies (thymoglobulin and alemtuz-mab) for induction is increasing6 Many centersill use these agents in low-risk patients toinimize exposure to other maintenance drugs

DIGORecommendations inChapter 2 InitialndMaintenance Immunosuppressiveedications

21 We recommend using a combination of immuno-suppressive medications as maintenance therapyincluding a CNI and an antiproliferative agentwith or without corticosteroids (1B)

22 We suggest that tacrolimus be the first-line CNIused (2A)221 We suggest that tacrolimus or CsA be

started before or at the time of transplanta-tion rather than delayed until the onset ofgraft function (2D tacrolimus 2B CsA)

23 We suggest that mycophenolate be the first-lineantiproliferative agent (2B)

24 We suggest that in patients who are at low immuno-logical risk and who receive induction therapycorticosteroids could be discontinued during thefirst week after transplantation (2B)

25 We recommend that if mTOR inhibitors areused they should not be started until graftfunction is established and surgical wounds arehealed (1B)

DOQIRationale andCommentary

Initial Immunosuppression

We agree that optimum initial maintenanceherapy includes a CNI and an antiproliferativegent and that tacrolimus is the preferred CNI forost patients The Symphony Study a largeulticenter clinical trial showed that the combi-

ation of low-dose tacrolimus mycophenolateofetil (MMF) and steroids with daclizumab

nduction provided superior efficacy without theegative impact on renal function compared withither cyclosporine or a CNI-free regimen ofow-dose sirolimus78 However in a small num-er of patients other issues such as age ethnic-ty risk of new-onset diabetes mellitus and pre-ious toxicity with tacrolimus may result in thenitial use of cyclosporine Immediate CNI useas not been shown to cause a delay in renalecovery Although many centers briefly hold orodify the CNI dose in the setting of delayed

raft function especially when using antilympho-yte-depleting induction agents treatment withhese drugs should be initiated before or at theime of discharge from the hospital and not

ithheld because of delayed graft function As m

tated mycophenolate compounds (MMF andycophenolate sodium) are used as the initial

ntiproliferative agent of choice in most USransplant centers

SteroidTherapyDiscontinuation

Steroid sparing with discontinuation withinhe first few weeks after transplant has gainedidespread acceptance in the United States withore than 25 of patients being discharged after

ransplant off steroid therapy6 Although theDOQI work group agreed that steroid therapy

ould be discontinued in low-risk patients afternduction therapy we did not think that thisuggestion should be accepted as a universaluideline for several reasons Although short-nd medium-term results in corticosteroid therapyiscontinuation protocols show equivalent pa-ient and graft survival there may be a price toay in the long term Acute rejection rates areigher in well-designed randomized clinical tri-ls of steroid withdrawal In addition the pres-nce of chronic interstitial fibrosis and tubulartrophy may be greater in corticosteroid-freeatients portending decreased long-term graftunction The heterogeneity of the US donor andecipient population may have a role in thisssue Newer transplant regimens decrease pred-isone dosage to 5 mgd Apart from less boneisease the potential metabolic benefits of corti-osteroid-free protocols versus 5 mgd seem toe less significant What is clear is that discontinu-tion of steroid therapy early after transplanteems to be associated with less risk of rejectionhan discontinuation of steroids later (1 year)t should be noted that there are no studies ofifferent times in the first year to determine whenorticosteroid therapy can be discontinued safelyn some centers steroid therapy discontinuations accomplished up to 6 months posttransplantate discontinuation of steroid therapy (1 yearosttransplant) is no longer recommended andorms the basis of KDIGO guideline 25 withhich we agree It also must be emphasized that

teroid therapy withdrawal should be performednly when there is close frequent monitoring ofhe patient

ncreased rejection rate with early use of theseompounds in place of CNIs The Symphonytudy showed that the highest rejection rateccurred in the arm using low-dose sirolimusith MMF and steroids78

DIGORecommendations inChapter 3ong-termMaintenance Immunosuppressiveedications

31 We suggest using the lowest planned doses ofmaintenance immunosuppressive medications by2-4 months after transplantation if there has beenno acute rejection (2C)

32 We suggest that CNIs be continued rather thanwithdrawn (2B)

32 If prednisone is being used beyond the first weekafter transplantation we suggest prednisone becontinued rather than withdrawn (2C)

DOQIRationale andCommentary

Decreasing ImmunosuppressiveDosage

Although our work group agreed with sugges-ion 31 we stress that dosing of immunosuppres-ion should at all times take into account thendividual patientrsquos risk profile balancing rejec-ion with the adverse effects of medications Inome patients this may mean higher drug dosingrug levels to account for a higher risk of rejec-ion Although most US transplant centers nowtrive for a lower dose of immunosuppressiveedication after the early posttransplant period

he transplant center should define each patientrsquosarget drug dosing based on immunologic riskhich depends on ethnicity age history of previ-us transplant and level of HLA antibodies

ContinueorWithdrawCNITherapy

Although we agreed that mTOR inhibitorshould not be used in the early posttransplanteriod78 newer clinical trials have exploredwitching from CNIs to mTOR inhibitors 3-6onths posttransplant910 Early results suggest

elative safety with improvement in renal func-ion Whether the trade-off of less nephrotoxic-ty with a different side-effect profile of mTORnhibitors will be beneficial in the long termemains to be determined The work groupelieved that suggestion 32 to continue CNI

herapy indefinitely in all patients required

ore study before it could be accepted as auideline

SteroidTherapyWithdrawal

We agree that late steroid therapy with-rawal (1 year) is inadvisable but stress thathe definition of ldquoearlyrdquo steroid discontinua-ion has not been well defined and may occurfter the first week (see commentary underhapter 2)

DIGORecommendations inChapter 4trategies toReduceDrugCosts

41 If drug costs block access to transplantation astrategy to minimize drug costs is appropriateeven if use of inferior drugs is necessary to obtainthe improved survival and quality of life benefitsof transplantation compared with dialysis (NotGraded)411 We suggest strategies that may reduce drug

costs includebull limiting use of a biologic agent for

induction to patients who are high-riskfor acute rejection (2C)

bull using ketoconazole to minimize CNIdose (2D)

bull using a nondihydropyridine CCB to mini-mize CNI dose (2C)

bull using azathioprine rather than mycophe-nolate (2B)

bull using adequately tested bioequivalent ge-neric drugs (2C)

bull using prednisone long-term (2C)

42 Do not use generic compounds that have not beencertified by an independent regulatory agency tomeet each of the following criteria when comparedto the reference compound (Not Graded)bull contains the same active ingredientbull is identical in strength dosage form and route of

administrationbull has the same use indicationsbull is bioequivalent in appropriate bioavailability

studiesbull meets the same batch requirements for identity

strength purity and qualitybull is manufactured under strict standards

43 It is important that the patient and the clinicianresponsible for the patientrsquos care be made aware ofany change in a prescribed immunosuppressivedrug including a change to a generic drug (NotGraded)

44 After switching to a generic medication that ismonitored using blood levels obtain levels andadjust the dose as often as necessary until a stable

therapeutic target is achieved (Not Graded)

DOQIRationale andCommentary

Drug costs are becoming an increasing issue inransplantation that impacts on patient adherencend ultimately affects graft survival Currently im-unosuppressive drugs in the United States are

overed by the Centers for Medicare amp Medicaidervices (CMS) the primary insurer for manyTRs for 3 years after transplant although legisla-

ion is being considered to continue this coverageor the life of the kidney Most KTRs are usingany other medications in addition to immunosup-

ressive drugs In general the transplant commu-ity (patients health care providers and policyakers) need to embrace the concept of cost con-

ainment and the risk(s) to the patient and graft byhese measures However this needs to be balancedy who benefits and how much risk is at stake

Use of drugs that block the cytochrome P-450A system in an attempt to decrease CNIosing and costs are rarely used in the Unitedtates The concern is that inadvertent cessa-

ion of treatment with these drugs causing aignificant decrease in drug levels could resultn an acute rejection episode Therefore theork group did not think that many of the 411

uggestions should be accepted as a guidelinewitching from a mycophenolate compound ton azathioprine compound in the later posttrans-lant period may be considered in some pa-ients as another cost-saving maneuver espe-ially in view of recent US registry datahowing similar long-term survival with theserugs11 Although we agree with the sugges-ions outlined in 42 it should be recognizedhat many generic formulations have nevereen tested in transplant patients Patient con-usion with medications when a different ge-eric formulation or even different strengths ofhe same drug from different manufacturers isispensed at each refill can lead to inadvertentedication errors possibly affecting out-

omes Patient education is crucial to avoidrrors in medication administration We agreeith recommendation 44 that it is crucial toonitor patients after an immunosuppressive

osage change brand change or change to aeneric drug However it needs to be recog-ized that implementation of this guideline canecome burdensome as practices become inun-

ated with inquiries from patients payors and 5

harmacies regarding medications Transplantenters and practices that see many transplantatients bear an inordinate part of this burden

DIGORecommendations inChapter 5onitoring ImmunosuppressiveMedications

51 We recommend measuring CNI blood levels(1B) and suggest measuring at leastbull every other day during the immediate postopera-

tive period until target levels are reached (2C)bull whenever there is a change in medication or

patient status that may affect blood levels (2C)bull whenever there is a decline in kidney function that

may indicate nephrotoxicity or rejection (2C)511 We suggest monitoring CsA using 12-h

trough (C0) 2-h post-dose (C2) or abbrevi-ated AUC (2D)

512 We suggest monitoring tacrolimus using12-h trough (C0) (2C)

52 We suggest monitoring MMF levels (2D)53 We suggest monitoring mTOR inhibitor levels (2C)

DOQIRationale andCommentary

Because immunosuppressive drugs are classi-ed as narrow therapeutic agents drug-levelonitoring is a necessary tool to maximize effi-

iency and minimize toxicity The blood drugevel is not synonymous with level of immuno-uppression but may correlate imperfectly withhis effect In most US transplant centers levelsf CNI and mTOR inhibitors are monitoredPA monitoring is problematic because of the

oor correlation between trough levels and areander the curve (AUC) exposure Optimal moni-oring of MPA requires a 4- to 6-hour abbrevi-ted AUC measurement which is logisticallyifficult in the outpatient setting Although stud-es show that monitoring MPA levels in the earlyosttransplant period may be helpful in cyclospor-ne-treated patients recent evidence suggests thatuch monitoring may be less important in pa-ients on tacrolimus therapy12 With most USTRs now being started on tacrolimus as theNI of choice MPA monitoring is not routine inany US transplant centers Although one per-

on in our work group believed there may still beome value in monitoring MPA levels the otherembers questioned the value and applicability

f this practice (KDIGO suggestion 52) Cur-ently many US centers measure MPA only inhe setting of possible drug-related toxicities oride effects Although we agree with suggestion

DIGORecommendations inChapter 6reatment ofAcuteRejection

61 We recommend biopsy before treating acuterejection unless the biopsy will substantiallydelay treatment (1C)

62 We suggest treating subclinical and borderline acuterejection (2D)

63 We recommend corticosteroids for the initialtreatment of acute cellular rejection (1D)631 We suggest adding or restoring maintenance

prednisone in patients not on steroids whohave a rejection episode (2D)

632 We suggest using lymphocyte-depleting anti-bodies or OKT3 [muromonab-CD3] for acutecellular rejections that do not respond tocorticosteroids and for recurrent acute cellu-lar rejections (2C)

64 We suggest treating antibody-mediated acute rejec-tion with one or more of the following alternativeswith or without corticosteroids (2C)bull plasma exchangebull intravenous immunoglobulinbull anti-CD20 antibodybull lymphocyte-depleting antibody

65 For patients who have a rejection episode wesuggest adding mycophenolate if the patient is notreceiving mycophenolate or azathioprine or switch-ing azathioprine to mycophenolate (2D)

DOQIRationale andCommentary

We concur that biopsies should be performed onll KTRs suspected of having an acute rejectionrecommendation 61) Expert interpretation of theiopsy specimen by pathologists accustomed toeading kidney transplant biopsies is as importants expertise in performing the biopsy It is contro-ersial whether subclinical and borderline rejec-ions should be treated (recommendation 62 sup-orted by low evidence [2D]) Subclinical rejectionsre diagnosed in patients who have protocol biop-ies performed by design not for deterioration inidney function Recent data suggest that the riskf subclinical rejection in patients on tacrolimusnd mycophenolate compound therapy is so lowhat protocol biopsies may no longer be indi-ated13 Whether this is true in patients with highmmunologic risk or patients on minimization pro-ocols (ie steroid-free protocols or lower CNI doses)s uncertain Whether borderline rejection shoulde treated or some infiltrates may be protective also

s uncertain In most US centers steroids are used d

ost frequently as first-line treatment for acuteejection followed by lymphocyte-depleting anti-odies in steroid-resistant rejection but there maye exceptions to this approach Decision makingegarding appropriate initial treatment for acuteejection should be based on clinical and patho-ogic information Timing of the rejection episodeosttransplant type of induction agent used beforeejection degree of deterioration in kidney functiont the time of rejection and histologic grade of theejection may influence selection of the appropriatenitial antirejection therapy There is increasingecognition of the role of antibody-mediated mecha-isms in acute rejection This process requirespecial blood tests (to detect donor-specific antibod-es) and histochemical stains (immunofluorescenceor C4d) for diagnosis14 Coordination with theransplant center is critical to ensure that all appro-riate testing is performed and specific treatment isnitiated After treatment of an acute episode opti-

Biopsy

Renal allograft biopsy is the gold standard foriagnosing the cause of a change in renal allo-raft function It is useful in all clinical situationsescribed in KDIGO suggestions 91-94 Poten-ial causes of allograft dysfunction include vol-me depletion compromised renal blood flowrinary outflow obstruction parenchymal causesuch as acute rejection (cellular andor humoral)hronic allograft nephropathy recurrent or deovo disease or BK nephropathy Patients show-ng a 20-25 increase in creatinine level aboveaseline values warrant consideration for biopsyther indications for pursuing renal allograftiopsy would be a less-than-expected responseo treatment of acute rejection The expectedesponse would be dependent on the severity ofissue injury noted on the diagnostic biopsy speci-

en Delayed graft function lasting longer than-7 days warrants biopsy with repeated biopsieserformed every 7-10 days until graft functionecovers New-onset proteinuria protein 20g creatinine or 20 g24 h also merits aidney biopsy De novo and recurrent glomerulariseases are common causes of new-onset pro-einuria Patients with de novo or recurrent glo-erular diseases should be followed up closely

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

treatment of infection posttransplant

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

ransplant practices in which these decisions tendo be transplant-center specific and based onactors described previously

DIGORecommendations inChapter 2 InitialndMaintenance Immunosuppressiveedications

21 We recommend using a combination of immuno-suppressive medications as maintenance therapyincluding a CNI and an antiproliferative agentwith or without corticosteroids (1B)

22 We suggest that tacrolimus be the first-line CNIused (2A)221 We suggest that tacrolimus or CsA be

started before or at the time of transplanta-tion rather than delayed until the onset ofgraft function (2D tacrolimus 2B CsA)

23 We suggest that mycophenolate be the first-lineantiproliferative agent (2B)

24 We suggest that in patients who are at low immuno-logical risk and who receive induction therapycorticosteroids could be discontinued during thefirst week after transplantation (2B)

25 We recommend that if mTOR inhibitors areused they should not be started until graftfunction is established and surgical wounds arehealed (1B)

DOQIRationale andCommentary

Initial Immunosuppression

We agree that optimum initial maintenanceherapy includes a CNI and an antiproliferativegent and that tacrolimus is the preferred CNI forost patients The Symphony Study a largeulticenter clinical trial showed that the combi-

ation of low-dose tacrolimus mycophenolateofetil (MMF) and steroids with daclizumab

nduction provided superior efficacy without theegative impact on renal function compared withither cyclosporine or a CNI-free regimen ofow-dose sirolimus78 However in a small num-er of patients other issues such as age ethnic-ty risk of new-onset diabetes mellitus and pre-ious toxicity with tacrolimus may result in thenitial use of cyclosporine Immediate CNI useas not been shown to cause a delay in renalecovery Although many centers briefly hold orodify the CNI dose in the setting of delayed

raft function especially when using antilympho-yte-depleting induction agents treatment withhese drugs should be initiated before or at theime of discharge from the hospital and not

ithheld because of delayed graft function As m

tated mycophenolate compounds (MMF andycophenolate sodium) are used as the initial

ntiproliferative agent of choice in most USransplant centers

SteroidTherapyDiscontinuation

Steroid sparing with discontinuation withinhe first few weeks after transplant has gainedidespread acceptance in the United States withore than 25 of patients being discharged after

ransplant off steroid therapy6 Although theDOQI work group agreed that steroid therapy

ould be discontinued in low-risk patients afternduction therapy we did not think that thisuggestion should be accepted as a universaluideline for several reasons Although short-nd medium-term results in corticosteroid therapyiscontinuation protocols show equivalent pa-ient and graft survival there may be a price toay in the long term Acute rejection rates areigher in well-designed randomized clinical tri-ls of steroid withdrawal In addition the pres-nce of chronic interstitial fibrosis and tubulartrophy may be greater in corticosteroid-freeatients portending decreased long-term graftunction The heterogeneity of the US donor andecipient population may have a role in thisssue Newer transplant regimens decrease pred-isone dosage to 5 mgd Apart from less boneisease the potential metabolic benefits of corti-osteroid-free protocols versus 5 mgd seem toe less significant What is clear is that discontinu-tion of steroid therapy early after transplanteems to be associated with less risk of rejectionhan discontinuation of steroids later (1 year)t should be noted that there are no studies ofifferent times in the first year to determine whenorticosteroid therapy can be discontinued safelyn some centers steroid therapy discontinuations accomplished up to 6 months posttransplantate discontinuation of steroid therapy (1 yearosttransplant) is no longer recommended andorms the basis of KDIGO guideline 25 withhich we agree It also must be emphasized that

teroid therapy withdrawal should be performednly when there is close frequent monitoring ofhe patient

elayed graft function and are no longer used inhe early posttransplant period (KDIGO recom-endation 25) Furthermore studies show an

ncreased rejection rate with early use of theseompounds in place of CNIs The Symphonytudy showed that the highest rejection rateccurred in the arm using low-dose sirolimusith MMF and steroids78

DIGORecommendations inChapter 3ong-termMaintenance Immunosuppressiveedications

31 We suggest using the lowest planned doses ofmaintenance immunosuppressive medications by2-4 months after transplantation if there has beenno acute rejection (2C)

32 We suggest that CNIs be continued rather thanwithdrawn (2B)

32 If prednisone is being used beyond the first weekafter transplantation we suggest prednisone becontinued rather than withdrawn (2C)

Drug costs are becoming an increasing issue inransplantation that impacts on patient adherencend ultimately affects graft survival Currently im-unosuppressive drugs in the United States are

overed by the Centers for Medicare amp Medicaidervices (CMS) the primary insurer for manyTRs for 3 years after transplant although legisla-

ion is being considered to continue this coverageor the life of the kidney Most KTRs are usingany other medications in addition to immunosup-

ressive drugs In general the transplant commu-ity (patients health care providers and policyakers) need to embrace the concept of cost con-

ainment and the risk(s) to the patient and graft byhese measures However this needs to be balancedy who benefits and how much risk is at stake

Use of drugs that block the cytochrome P-450A system in an attempt to decrease CNIosing and costs are rarely used in the Unitedtates The concern is that inadvertent cessa-

ion of treatment with these drugs causing aignificant decrease in drug levels could resultn an acute rejection episode Therefore theork group did not think that many of the 411

uggestions should be accepted as a guidelinewitching from a mycophenolate compound ton azathioprine compound in the later posttrans-lant period may be considered in some pa-ients as another cost-saving maneuver espe-ially in view of recent US registry datahowing similar long-term survival with theserugs11 Although we agree with the sugges-ions outlined in 42 it should be recognizedhat many generic formulations have nevereen tested in transplant patients Patient con-usion with medications when a different ge-eric formulation or even different strengths ofhe same drug from different manufacturers isispensed at each refill can lead to inadvertentedication errors possibly affecting out-

omes Patient education is crucial to avoidrrors in medication administration We agreeith recommendation 44 that it is crucial toonitor patients after an immunosuppressive

osage change brand change or change to aeneric drug However it needs to be recog-ized that implementation of this guideline canecome burdensome as practices become inun-

ated with inquiries from patients payors and 5

harmacies regarding medications Transplantenters and practices that see many transplantatients bear an inordinate part of this burden

DIGORecommendations inChapter 5onitoring ImmunosuppressiveMedications

51 We recommend measuring CNI blood levels(1B) and suggest measuring at leastbull every other day during the immediate postopera-

tive period until target levels are reached (2C)bull whenever there is a change in medication or

patient status that may affect blood levels (2C)bull whenever there is a decline in kidney function that

may indicate nephrotoxicity or rejection (2C)511 We suggest monitoring CsA using 12-h

DOQIRationale andCommentary

Because immunosuppressive drugs are classi-ed as narrow therapeutic agents drug-levelonitoring is a necessary tool to maximize effi-

iency and minimize toxicity The blood drugevel is not synonymous with level of immuno-uppression but may correlate imperfectly withhis effect In most US transplant centers levelsf CNI and mTOR inhibitors are monitoredPA monitoring is problematic because of the

oor correlation between trough levels and areander the curve (AUC) exposure Optimal moni-oring of MPA requires a 4- to 6-hour abbrevi-ted AUC measurement which is logisticallyifficult in the outpatient setting Although stud-es show that monitoring MPA levels in the earlyosttransplant period may be helpful in cyclospor-ne-treated patients recent evidence suggests thatuch monitoring may be less important in pa-ients on tacrolimus therapy12 With most USTRs now being started on tacrolimus as theNI of choice MPA monitoring is not routine inany US transplant centers Although one per-

on in our work group believed there may still beome value in monitoring MPA levels the otherembers questioned the value and applicability

f this practice (KDIGO suggestion 52) Cur-ently many US centers measure MPA only inhe setting of possible drug-related toxicities oride effects Although we agree with suggestion

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

Decreasing ImmunosuppressiveDosage

DOQIRationale andCommentary

Drug costs are becoming an increasing issue inransplantation that impacts on patient adherencend ultimately affects graft survival Currently im-unosuppressive drugs in the United States are

overed by the Centers for Medicare amp Medicaidervices (CMS) the primary insurer for manyTRs for 3 years after transplant although legisla-

ion is being considered to continue this coverageor the life of the kidney Most KTRs are usingany other medications in addition to immunosup-

ressive drugs In general the transplant commu-ity (patients health care providers and policyakers) need to embrace the concept of cost con-

ainment and the risk(s) to the patient and graft byhese measures However this needs to be balancedy who benefits and how much risk is at stake

Use of drugs that block the cytochrome P-450A system in an attempt to decrease CNIosing and costs are rarely used in the Unitedtates The concern is that inadvertent cessa-

ion of treatment with these drugs causing aignificant decrease in drug levels could resultn an acute rejection episode Therefore theork group did not think that many of the 411

uggestions should be accepted as a guidelinewitching from a mycophenolate compound ton azathioprine compound in the later posttrans-lant period may be considered in some pa-ients as another cost-saving maneuver espe-ially in view of recent US registry datahowing similar long-term survival with theserugs11 Although we agree with the sugges-ions outlined in 42 it should be recognizedhat many generic formulations have nevereen tested in transplant patients Patient con-usion with medications when a different ge-eric formulation or even different strengths ofhe same drug from different manufacturers isispensed at each refill can lead to inadvertentedication errors possibly affecting out-

omes Patient education is crucial to avoidrrors in medication administration We agreeith recommendation 44 that it is crucial toonitor patients after an immunosuppressive

osage change brand change or change to aeneric drug However it needs to be recog-ized that implementation of this guideline canecome burdensome as practices become inun-

ated with inquiries from patients payors and 5

harmacies regarding medications Transplantenters and practices that see many transplantatients bear an inordinate part of this burden

DIGORecommendations inChapter 5onitoring ImmunosuppressiveMedications

51 We recommend measuring CNI blood levels(1B) and suggest measuring at leastbull every other day during the immediate postopera-

tive period until target levels are reached (2C)bull whenever there is a change in medication or

patient status that may affect blood levels (2C)bull whenever there is a decline in kidney function that

may indicate nephrotoxicity or rejection (2C)511 We suggest monitoring CsA using 12-h

trough (C0) 2-h post-dose (C2) or abbrevi-ated AUC (2D)

512 We suggest monitoring tacrolimus using12-h trough (C0) (2C)

52 We suggest monitoring MMF levels (2D)53 We suggest monitoring mTOR inhibitor levels (2C)

DOQIRationale andCommentary

Because immunosuppressive drugs are classi-ed as narrow therapeutic agents drug-levelonitoring is a necessary tool to maximize effi-

iency and minimize toxicity The blood drugevel is not synonymous with level of immuno-uppression but may correlate imperfectly withhis effect In most US transplant centers levelsf CNI and mTOR inhibitors are monitoredPA monitoring is problematic because of the

oor correlation between trough levels and areander the curve (AUC) exposure Optimal moni-oring of MPA requires a 4- to 6-hour abbrevi-ted AUC measurement which is logisticallyifficult in the outpatient setting Although stud-es show that monitoring MPA levels in the earlyosttransplant period may be helpful in cyclospor-ne-treated patients recent evidence suggests thatuch monitoring may be less important in pa-ients on tacrolimus therapy12 With most USTRs now being started on tacrolimus as theNI of choice MPA monitoring is not routine inany US transplant centers Although one per-

on in our work group believed there may still beome value in monitoring MPA levels the otherembers questioned the value and applicability

f this practice (KDIGO suggestion 52) Cur-ently many US centers measure MPA only inhe setting of possible drug-related toxicities oride effects Although we agree with suggestion

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

DIGORecommendations inChapter 11reventingDetecting andTreatingonadherence

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

Hepatitis C management posttransplant is ahallenge The KDIGO guidelines cited hereere based on the recently published KDIGOuideline for hepatitis C in CKD4 Hepatitis Cypically is not treated posttransplant because ofhe risk (50) of rejection precipitated bynterferon therapy particularly in US KTRs inhom hepatitis C commonly is genotype 1 which

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

treatment of infection posttransplant

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

Hypertension

The KDIGO work group adapted the KDOQI004 recommendations for target blood pres-ure in KTRs55 Self measurement is useful inssessing response to therapy and enhancesdherence56 In general we agree that the classf antihypertensive agent does not matter inhe treatment of blood pressure elevation inhis population and that attention should beiven to potential side effects of antihyperten-ive agents as well as possible interactionsith the immunosuppressive regimen (eg non-ihydropyridine calcium channel blockers andNIs) In the absence of adequate randomizedontrolled trials it is not known whether angio-ensin-converting enzyme (ACE) inhibitors andngiotensin receptor blockers (ARBs) prolongecipient or allograft survival Some but notll retrospective studies suggest a benefitowever all these studies are limited by selec-ion bias5758 Although ACE inhibitors andRBs commonly lead to some decrease inFR treatment with these drugs should be

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

Drug costs are becoming an increasing issue inransplantation that impacts on patient adherencend ultimately affects graft survival Currently im-unosuppressive drugs in the United States are

overed by the Centers for Medicare amp Medicaidervices (CMS) the primary insurer for manyTRs for 3 years after transplant although legisla-

ion is being considered to continue this coverageor the life of the kidney Most KTRs are usingany other medications in addition to immunosup-

ressive drugs In general the transplant commu-ity (patients health care providers and policyakers) need to embrace the concept of cost con-

ainment and the risk(s) to the patient and graft byhese measures However this needs to be balancedy who benefits and how much risk is at stake

Use of drugs that block the cytochrome P-450A system in an attempt to decrease CNIosing and costs are rarely used in the Unitedtates The concern is that inadvertent cessa-

ion of treatment with these drugs causing aignificant decrease in drug levels could resultn an acute rejection episode Therefore theork group did not think that many of the 411

uggestions should be accepted as a guidelinewitching from a mycophenolate compound ton azathioprine compound in the later posttrans-lant period may be considered in some pa-ients as another cost-saving maneuver espe-ially in view of recent US registry datahowing similar long-term survival with theserugs11 Although we agree with the sugges-ions outlined in 42 it should be recognizedhat many generic formulations have nevereen tested in transplant patients Patient con-usion with medications when a different ge-eric formulation or even different strengths ofhe same drug from different manufacturers isispensed at each refill can lead to inadvertentedication errors possibly affecting out-

omes Patient education is crucial to avoidrrors in medication administration We agreeith recommendation 44 that it is crucial toonitor patients after an immunosuppressive

osage change brand change or change to aeneric drug However it needs to be recog-ized that implementation of this guideline canecome burdensome as practices become inun-

ated with inquiries from patients payors and 5

harmacies regarding medications Transplantenters and practices that see many transplantatients bear an inordinate part of this burden

DIGORecommendations inChapter 5onitoring ImmunosuppressiveMedications

51 We recommend measuring CNI blood levels(1B) and suggest measuring at leastbull every other day during the immediate postopera-

tive period until target levels are reached (2C)bull whenever there is a change in medication or

patient status that may affect blood levels (2C)bull whenever there is a decline in kidney function that

may indicate nephrotoxicity or rejection (2C)511 We suggest monitoring CsA using 12-h

trough (C0) 2-h post-dose (C2) or abbrevi-ated AUC (2D)

512 We suggest monitoring tacrolimus using12-h trough (C0) (2C)

52 We suggest monitoring MMF levels (2D)53 We suggest monitoring mTOR inhibitor levels (2C)

DOQIRationale andCommentary

Because immunosuppressive drugs are classi-ed as narrow therapeutic agents drug-levelonitoring is a necessary tool to maximize effi-

iency and minimize toxicity The blood drugevel is not synonymous with level of immuno-uppression but may correlate imperfectly withhis effect In most US transplant centers levelsf CNI and mTOR inhibitors are monitoredPA monitoring is problematic because of the

oor correlation between trough levels and areander the curve (AUC) exposure Optimal moni-oring of MPA requires a 4- to 6-hour abbrevi-ted AUC measurement which is logisticallyifficult in the outpatient setting Although stud-es show that monitoring MPA levels in the earlyosttransplant period may be helpful in cyclospor-ne-treated patients recent evidence suggests thatuch monitoring may be less important in pa-ients on tacrolimus therapy12 With most USTRs now being started on tacrolimus as theNI of choice MPA monitoring is not routine inany US transplant centers Although one per-

on in our work group believed there may still beome value in monitoring MPA levels the otherembers questioned the value and applicability

f this practice (KDIGO suggestion 52) Cur-ently many US centers measure MPA only inhe setting of possible drug-related toxicities oride effects Although we agree with suggestion

71 We recommend kidney allograft biopsy for allpatients with declining kidney function of unclearcause to detect potentially reversible causes (1C)

72 For patients with CAI and histological evidence ofCNI toxicity we suggest reducing withdrawing orreplacing the CNI (2C)721 For patients with CAI eGFR 40 mLmin

empts at decreasing the dosage have failed Onelso must ensure that all other causes of CAI arexcluded to avoid inappropriate drug adjustmentsr missed treatment options Although our workroup thought that KDIGO suggestion 721 maye reasonable in some patients we also want tomphasize that the role of mTOR inhibitors in thereatment of CAICNI toxicity is poorly defined Its clear that switching from a CNI to an mTORnhibitor should be avoided in patients with se-erely decreased glomerular filtration rate (GFR)ndor the presence of proteinuria however the exactuidelines for when to switch are still evolving

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

ransplant centers and may become a standardethod of transplant biopsy analysis in the fu-

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

ased on a consensus of opinion Despite this we

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

DIGORecommendations inChapter 6reatment ofAcuteRejection

61 We recommend biopsy before treating acuterejection unless the biopsy will substantiallydelay treatment (1C)

62 We suggest treating subclinical and borderline acuterejection (2D)

63 We recommend corticosteroids for the initialtreatment of acute cellular rejection (1D)631 We suggest adding or restoring maintenance

prednisone in patients not on steroids whohave a rejection episode (2D)

632 We suggest using lymphocyte-depleting anti-bodies or OKT3 [muromonab-CD3] for acutecellular rejections that do not respond tocorticosteroids and for recurrent acute cellu-lar rejections (2C)

64 We suggest treating antibody-mediated acute rejec-tion with one or more of the following alternativeswith or without corticosteroids (2C)bull plasma exchangebull intravenous immunoglobulinbull anti-CD20 antibodybull lymphocyte-depleting antibody

65 For patients who have a rejection episode wesuggest adding mycophenolate if the patient is notreceiving mycophenolate or azathioprine or switch-ing azathioprine to mycophenolate (2D)

DIGORecommendations inChapter 7reatment of ChronicAllograft Injury (CAI)

71 We recommend kidney allograft biopsy for allpatients with declining kidney function of unclearcause to detect potentially reversible causes (1C)

72 For patients with CAI and histological evidence ofCNI toxicity we suggest reducing withdrawing orreplacing the CNI (2C)721 For patients with CAI eGFR 40 mLmin

173 m2 and urine total protein excretion500 mgg creatinine (or equivalent protein-uria by other measures) we suggest replac-ing the CNI with a mTOR inhibitor (2D)

ories Therefore coordination with the transplantenter where these techniques are available is essen-ial For patients with CAI caused by CNI toxicityithdrawing the CNI should occur only after at-

empts at decreasing the dosage have failed Onelso must ensure that all other causes of CAI arexcluded to avoid inappropriate drug adjustmentsr missed treatment options Although our workroup thought that KDIGO suggestion 721 maye reasonable in some patients we also want tomphasize that the role of mTOR inhibitors in thereatment of CAICNI toxicity is poorly defined Its clear that switching from a CNI to an mTORnhibitor should be avoided in patients with se-erely decreased glomerular filtration rate (GFR)ndor the presence of proteinuria however the exactuidelines for when to switch are still evolving

Biopsy

Renal allograft biopsy is the gold standard foriagnosing the cause of a change in renal allo-raft function It is useful in all clinical situationsescribed in KDIGO suggestions 91-94 Poten-ial causes of allograft dysfunction include vol-me depletion compromised renal blood flowrinary outflow obstruction parenchymal causesuch as acute rejection (cellular andor humoral)hronic allograft nephropathy recurrent or deovo disease or BK nephropathy Patients show-ng a 20-25 increase in creatinine level aboveaseline values warrant consideration for biopsyther indications for pursuing renal allograftiopsy would be a less-than-expected responseo treatment of acute rejection The expectedesponse would be dependent on the severity ofissue injury noted on the diagnostic biopsy speci-

en Delayed graft function lasting longer than-7 days warrants biopsy with repeated biopsieserformed every 7-10 days until graft functionecovers New-onset proteinuria protein 20g creatinine or 20 g24 h also merits aidney biopsy De novo and recurrent glomerulariseases are common causes of new-onset pro-einuria Patients with de novo or recurrent glo-erular diseases should be followed up closely

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

ased on a consensus of opinion Despite this we

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

Biopsy

Renal allograft biopsy is the gold standard foriagnosing the cause of a change in renal allo-raft function It is useful in all clinical situationsescribed in KDIGO suggestions 91-94 Poten-ial causes of allograft dysfunction include vol-me depletion compromised renal blood flowrinary outflow obstruction parenchymal causesuch as acute rejection (cellular andor humoral)hronic allograft nephropathy recurrent or deovo disease or BK nephropathy Patients show-ng a 20-25 increase in creatinine level aboveaseline values warrant consideration for biopsyther indications for pursuing renal allograftiopsy would be a less-than-expected responseo treatment of acute rejection The expectedesponse would be dependent on the severity ofissue injury noted on the diagnostic biopsy speci-

en Delayed graft function lasting longer than-7 days warrants biopsy with repeated biopsieserformed every 7-10 days until graft functionecovers New-onset proteinuria protein 20g creatinine or 20 g24 h also merits aidney biopsy De novo and recurrent glomerulariseases are common causes of new-onset pro-einuria Patients with de novo or recurrent glo-erular diseases should be followed up closely

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

ransplant centers and may become a standardethod of transplant biopsy analysis in the fu-

DIGORecommendations inChapter 10ecurrentDisease

101 We suggest screening KTRs with primary kidneydisease caused by FSGS for proteinuria (2C) atleastbull Daily for 1 week (2D)bull Weekly for 4 weeks (2D)bull Every 3 months for the first year (2D) Every

year thereafter (2D)

102 We suggest screening KTRs with potentially treat-able recurrence of primary kidney disease fromIgA nephropathy MPGN anti-GBM disease orANCA-associated vasculitis for microhematuria(2C) at leastbull Once in the first month to determine a baseline

(2D)bull Every 3 months during the first year (2D)

Annually thereafter (2D)

103 During episodes of graft dysfunction in patientswith primary HUS we suggest screening forthrombotic microangiopathy (eg with plateletcount peripheral smear for blood cell morphologyplasma haptoglobin and serum lactate dehydroge-nase) (2D)

104 When screening suggests possible treatable recur-rent disease we suggest obtaining an allograftbiopsy (2C)

1052 We suggest high-dose corticosteroids andcyclophosphamide in patients with recur-rent ANCA-associated vasculitis or anti-GBM disease (2D)

1053 We suggest using an ACE-I [ACE inhibi-tor] or an ARB for patients with recurrentglomerulonephritis and proteinuria (2C)

1054 For KTRs with primary hyperoxaluriawe suggest appropriate measures to pre-vent oxalate deposition until plasma andurine oxalate levels are normal (2C)includingbull Pyridoxine (2C)bull High calcium and low oxalate diet

(2C)bull Increased oral fluid intake to enhance

urinary dilution of oxalate (2C)bull Potassium or sodium citrate to alkalin-

ize the urine (2C)bull Orthophosphate (2C)bull Magnesium oxide (2C)bull Intensive hemodialysis to remove ox-

alate (2C)

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

HerpesandVaricella

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

Hepatitis C management posttransplant is ahallenge The KDIGO guidelines cited hereere based on the recently published KDIGOuideline for hepatitis C in CKD4 Hepatitis Cypically is not treated posttransplant because ofhe risk (50) of rejection precipitated bynterferon therapy particularly in US KTRs inhom hepatitis C commonly is genotype 1 which

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

treatment of infection posttransplant

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

Hypertension

The KDIGO work group adapted the KDOQI004 recommendations for target blood pres-ure in KTRs55 Self measurement is useful inssessing response to therapy and enhancesdherence56 In general we agree that the classf antihypertensive agent does not matter inhe treatment of blood pressure elevation inhis population and that attention should beiven to potential side effects of antihyperten-ive agents as well as possible interactionsith the immunosuppressive regimen (eg non-ihydropyridine calcium channel blockers andNIs) In the absence of adequate randomizedontrolled trials it is not known whether angio-ensin-converting enzyme (ACE) inhibitors andngiotensin receptor blockers (ARBs) prolongecipient or allograft survival Some but notll retrospective studies suggest a benefitowever all these studies are limited by selec-ion bias5758 Although ACE inhibitors andRBs commonly lead to some decrease inFR treatment with these drugs should be

Dyslipidemia

The KDIGO work group based their recom-endations for evaluation and treatment of

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

Biopsy

Renal allograft biopsy is the gold standard foriagnosing the cause of a change in renal allo-raft function It is useful in all clinical situationsescribed in KDIGO suggestions 91-94 Poten-ial causes of allograft dysfunction include vol-me depletion compromised renal blood flowrinary outflow obstruction parenchymal causesuch as acute rejection (cellular andor humoral)hronic allograft nephropathy recurrent or deovo disease or BK nephropathy Patients show-ng a 20-25 increase in creatinine level aboveaseline values warrant consideration for biopsyther indications for pursuing renal allograftiopsy would be a less-than-expected responseo treatment of acute rejection The expectedesponse would be dependent on the severity ofissue injury noted on the diagnostic biopsy speci-

en Delayed graft function lasting longer than-7 days warrants biopsy with repeated biopsieserformed every 7-10 days until graft functionecovers New-onset proteinuria protein 20g creatinine or 20 g24 h also merits aidney biopsy De novo and recurrent glomerulariseases are common causes of new-onset pro-einuria Patients with de novo or recurrent glo-erular diseases should be followed up closely

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

ransplant centers and may become a standardethod of transplant biopsy analysis in the fu-

ure

DIGORecommendations inChapter 10ecurrentDisease

101 We suggest screening KTRs with primary kidneydisease caused by FSGS for proteinuria (2C) atleastbull Daily for 1 week (2D)bull Weekly for 4 weeks (2D)bull Every 3 months for the first year (2D) Every

year thereafter (2D)

102 We suggest screening KTRs with potentially treat-able recurrence of primary kidney disease fromIgA nephropathy MPGN anti-GBM disease orANCA-associated vasculitis for microhematuria(2C) at leastbull Once in the first month to determine a baseline

(2D)bull Every 3 months during the first year (2D)

1052 We suggest high-dose corticosteroids andcyclophosphamide in patients with recur-rent ANCA-associated vasculitis or anti-GBM disease (2D)

1053 We suggest using an ACE-I [ACE inhibi-tor] or an ARB for patients with recurrentglomerulonephritis and proteinuria (2C)

1054 For KTRs with primary hyperoxaluriawe suggest appropriate measures to pre-vent oxalate deposition until plasma andurine oxalate levels are normal (2C)includingbull Pyridoxine (2C)bull High calcium and low oxalate diet

(2C)bull Increased oral fluid intake to enhance

urinary dilution of oxalate (2C)bull Potassium or sodium citrate to alkalin-

alate (2C)

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

ased on a consensus of opinion Despite this we

DIGORecommendations inChapter 11reventingDetecting andTreatingonadherence

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

DIGORecommendations inChapter 12accination

121 We recommend giving all KTRs approvedinactivated vaccines according to recommendedschedules for the general population except forHBV vaccination (1D)1211 We suggest HBV vaccination (ideally

prior to transplantation) and HBsAb titers6-12 weeks after completing the vaccina-

tion series (2D) h

12111 We suggest annual HBsAb[antibody to hepatitis B sur-face antigen] titers (2D)

12112 We suggest revaccination ifthe antibody titer falls below10 mIUmL (2D)

122 We suggest avoiding live vaccines in KTRs (2C)123 We suggest avoiding vaccinations except influ-

enza vaccination in the first 6 months followingkidney transplantation (2C)1231 We suggest resuming immunizations once

patients are receiving minimal mainte-nance doses of immunosuppressive medi-cations (2C)

1232 We recommend giving all KTRs whoare at least 1-month post-transplantinfluenza vaccination prior to the onsetof the annual influenza season regard-less of status of immunosuppression(1C)

124 We suggest giving the following vaccines to KTRswho due to age direct exposure residence ortravel to endemic areas or other epidemiologicalrisk factors are at increased risk for the specificdiseasesbull rabies (2D)bull tick-borne meningoencephalitis (2D)bull Japanese B encephalitismdashinactivated (2D)bull Meningococcus (2D)bull Pneumococcus (2D)bull Salmonella typhimdashinactivated (2D)1241 Consult an infectious disease specialist a

itis B antibody titers annually is a commonractice in the United States Hepatitis B is nots prevalent in the United States as in otherarts of the world and evidence supportingcreening in all patients posttransplant is lack-ng However screening for seroconversion inatients at risk (receiving a hepatitis B corentibodyndashpositive kidney) is appropriate Theseatients may benefit from lamivudine or ente-avir therapy36

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DIGORecommendations inChapter 13 Viraliseases

131 BK POLYOMA VIRUS1311 We suggest screening all KTRs for BKV

with quantitative plasma NAT (2C) atleastbull monthly for the first 3-6 months after

transplantation (2D)bull then every 3 months until the end of

the first post-transplant year (2D)bull whenever there is an unexplained rise

in serum creatinine (2D)bull and after treatment for acute rejection

(2D)1312 We suggest reducing immunosuppressive

medications when BKV plasma NAT is

persistently greater than 10 000 cop-iesmL (107 copiesL) (2D)

132 CYTOMEGALOVIRUS1321 CMV prophylaxis We recommend that

KTRs (except when donor and recipi-ent both have negative CMV serolo-gies) receive chemoprophylaxis forCMV infection with oral ganciclovir orvalganciclovir for at least 3 monthsafter transplantation (1B) and for 6weeks after treatment with a T-cellndashdepleting antibody (1C)

1322 In patients with CMV disease we suggestweekly monitoring of CMV by NAT orpp65 antigenemia (2D)

1323 CMV treatment13231 We recommend that all pa-

tients with serious (includ-ing most patients with tissueinvasive) CMV disease betreated with intravenousganciclovir (1D)

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

Biopsy

Renal allograft biopsy is the gold standard foriagnosing the cause of a change in renal allo-raft function It is useful in all clinical situationsescribed in KDIGO suggestions 91-94 Poten-ial causes of allograft dysfunction include vol-me depletion compromised renal blood flowrinary outflow obstruction parenchymal causesuch as acute rejection (cellular andor humoral)hronic allograft nephropathy recurrent or deovo disease or BK nephropathy Patients show-ng a 20-25 increase in creatinine level aboveaseline values warrant consideration for biopsyther indications for pursuing renal allograftiopsy would be a less-than-expected responseo treatment of acute rejection The expectedesponse would be dependent on the severity ofissue injury noted on the diagnostic biopsy speci-

en Delayed graft function lasting longer than-7 days warrants biopsy with repeated biopsieserformed every 7-10 days until graft functionecovers New-onset proteinuria protein 20g creatinine or 20 g24 h also merits aidney biopsy De novo and recurrent glomerulariseases are common causes of new-onset pro-einuria Patients with de novo or recurrent glo-erular diseases should be followed up closely

y transplant nephrologists or community neph-ologists with close communication with theransplant center because treatment of some recur-ent kidney diseases may prevent or delay thenset of graft failure2324

SafetyandAccuracy

The safety of kidney transplant biopsies haseen documented and the overall risk of compli-ations is low Most biopsies are performed inhe transplant center by transplant nephrologistsommunity nephrologists also may perform bi-psies of the kidney in KTRs more than a yearosttransplant It is prudent to obtain a diagnosticltrasound before biopsy to rule out unexpectedlterations in blood flow or urinary tract obstruc-ion It is imperative that a pathologist familiar

ith the transplant process interprets the pathol-

gy in consultation with the referring nephrolo-ist using appropriate stains and other studies

MolecularMarkers

In addition to conventional histopathologicxamination several US transplant centers aresing molecular markers as well as genomic orroteomic methods to enhance our understand-ng of the mechanism of immunologic and non-mmunologic pathway of injury As an exampleolymerase chain reaction (PCR) has been usedo detect messenger RNA for IL-2 and otheriomarkers in biopsy samples Using this ap-roach IL-2 upregulated during rejection coulde detected 2 days before rejection was apparentsing histologic or clinical criteria Such PCRpproaches have been used to detect other generoducts upregulated during acute rejection suchs granzyme B perforin transforming growthactor IL-10 and IL-1525-27 These newerethods are performed almost exclusively in

ransplant centers and may become a standardethod of transplant biopsy analysis in the fu-

urinary dilution of oxalate (2C)bull Potassium or sodium citrate to alkalin-

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

ased on a consensus of opinion Despite this we

DIGORecommendations inChapter 11reventingDetecting andTreatingonadherence

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

DIGORecommendations inChapter 12accination

121 We recommend giving all KTRs approvedinactivated vaccines according to recommendedschedules for the general population except forHBV vaccination (1D)1211 We suggest HBV vaccination (ideally

prior to transplantation) and HBsAb titers6-12 weeks after completing the vaccina-

tion series (2D) h

12111 We suggest annual HBsAb[antibody to hepatitis B sur-face antigen] titers (2D)

12112 We suggest revaccination ifthe antibody titer falls below10 mIUmL (2D)

122 We suggest avoiding live vaccines in KTRs (2C)123 We suggest avoiding vaccinations except influ-

enza vaccination in the first 6 months followingkidney transplantation (2C)1231 We suggest resuming immunizations once

patients are receiving minimal mainte-nance doses of immunosuppressive medi-cations (2C)

1232 We recommend giving all KTRs whoare at least 1-month post-transplantinfluenza vaccination prior to the onsetof the annual influenza season regard-less of status of immunosuppression(1C)

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DIGORecommendations inChapter 13 Viraliseases

131 BK POLYOMA VIRUS1311 We suggest screening all KTRs for BKV

with quantitative plasma NAT (2C) atleastbull monthly for the first 3-6 months after

transplantation (2D)bull then every 3 months until the end of

the first post-transplant year (2D)bull whenever there is an unexplained rise

persistently greater than 10 000 cop-iesmL (107 copiesL) (2D)

132 CYTOMEGALOVIRUS1321 CMV prophylaxis We recommend that

KTRs (except when donor and recipi-ent both have negative CMV serolo-gies) receive chemoprophylaxis forCMV infection with oral ganciclovir orvalganciclovir for at least 3 monthsafter transplantation (1B) and for 6weeks after treatment with a T-cellndashdepleting antibody (1C)

134 HERPES SIMPLEX VIRUS 1 2 AND VARI-CELLA ZOSTER VIRUS1341 We recommend that KTRs who de-

velop a superficial HSV 1 2 infectionbe treated (1B) with an appropriateoral antiviral agent (eg acyclovir vala-cyclovir or famciclovir) until all le-sions have resolved (1D)

1342 We recommend that KTRs with sys-temic HSV 1 2 infection be treated(1B) with intravenous acyclovir and areduction in immunosuppressive medi-cation (1D)13421 We recommend that intrave-

1343 We suggest using a prophylactic antiviralagent for KTRs experiencing frequentrecurrences of HSV 12 infection (2D)

1344 We recommend that primary VZV infec-tion (chicken pox) in KTRs be treated(1C) with either intravenous or oral acy-clovir or valacyclovir and a temporaryreduction in amount of immunosuppres-sive medication (2D)

135 HEPATITIS C VIRUS1351 We suggest that HCV-infected KTRs be

treated only when the benefits of treat-ment clearly outweigh the risk of allo-graft rejection due to interferon-basedtherapy (eg fibrosing cholestatic hepati-tis life-threatening vasculitis) (2D)[Based on KDIGO Hepatitis C Recom-mendation 215]

1352 We suggest monotherapy with standardinterferon for HCV-infected KTRs inwhom the benefits of antiviral treatmentclearly outweigh the risks (2D) [Basedon KDIGO Hepatitis C Recommenda-tions 224 and 442]

infection (Not Graded)1372 To determine antiretroviral therapy refer

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

dults EBV-induced posttransplant lymphoprolif-rative disorder (PTLD) affects many more pediat-ic than adult KTRs If screening is someday to beoutinely implemented in US centers details regard-ng the best method of screening and levels ofiremia above which a clinical intervention should

HerpesandVaricella

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

in those with primary FSGS as theirprimary kidney disease (2D)

1052 We suggest high-dose corticosteroids andcyclophosphamide in patients with recur-rent ANCA-associated vasculitis or anti-GBM disease (2D)

1053 We suggest using an ACE-I [ACE inhibi-tor] or an ARB for patients with recurrentglomerulonephritis and proteinuria (2C)

1054 For KTRs with primary hyperoxaluriawe suggest appropriate measures to pre-vent oxalate deposition until plasma andurine oxalate levels are normal (2C)includingbull Pyridoxine (2C)bull High calcium and low oxalate diet

(2C)bull Increased oral fluid intake to enhance

urinary dilution of oxalate (2C)bull Potassium or sodium citrate to alkalin-

DOQIRationale andCommentary

Recurrent disease accounts for a substantialmount of graft loss after renal transplant It isifficult to assess the percentage of grafts lost toecurrent disease because many patients presentith end-stage renal disease without benefit of aiagnostic native renal biopsy The likelihood ofecurrent disease after transplant is dependent onhe disease with certain diseases at particularlyigh risk of recurrence28

Recurrent Focal SegmentalGlomerulosclerosis

We agree with recommendation 101 regard-ng frequent and regular screening for protein-ria in patients with primary focal segmentallomerulosclerosis (FSGS) as the cause of end-tage renal disease If the patient is still produc-ng urine at the time of transplant a preoperativerine protein-creatinine ratio can be a very help-ul baseline measure of proteinuria Early detec-ion of FSGS recurrence which can present withormal light microscopy but foot-process efface-ent on electron microscopy29 provides the best

pportunity for intervention and amelioration ofisease

IgANephropathy

Recurrence rates of immunoglobulin A (IgA)

ephropathy are variable We agree with recom- b

endation 102 for screening routinely for micro-ematuria Recurrent disease is confirmed with aenal allograft biopsy Histologic recurrence ofisease is much more common than is clinicalisease recurrence There is no proven therapyor treatment of recurrent disease30

MembranoproliferativeGlomerulonephritis

Recurrence of membranoproliferative glomer-lonephritis (MPGN) is common as high as 80ith MPGN type II (dense-deposit disease) Theost common cause of MPGN type I is hepatitisndashassociated immune complex formation Wegree with the proposed regularly scheduledcreening for microhematuria and proteinuria inecommendation 102 Patients with known hepa-itis Cndashassociated MPGN pretransplant also maye screened for cryoglobulins which are associ-ted with MPGN31

HemolyticUremic Syndrome

Hemolytic uremic syndrome (HUS) typicallys divided into diarrheal associated (D) andonndashdiarrheal associated (D) D disease oc-urs mostly in children and rarely recurs post-ransplant However D HUS is more commonn adults and can recur In HUS associated with aomplement abnormality such as factor H defi-iency or factor I mutation recurrence rates cane as high as 80 Screening for evidence ofecurrence allows for an earlier diagnosis whichill require biopsy in most cases and provides

n opportunity for earlier intervention There iso comment in the guideline regarding recur-ence of thrombotic thrombocytopenic purpuraut early detection of recurrence provides anpportunity for treatment with plasmapheresisnd intravenous immune globulin (IVIG)

BiopsyandTreatment

As stated kidney biopsy and interpretation bypathologist with expertise in transplant speci-en readings is critical in the diagnosis of dis-

ase recurrence Treatment for most recurrentisease in renal transplantation is based on aombination of case reports case cohorts andetrospective reviews Recurrent diseases post-ransplant are not common enough that random-zed controlled trials can be implemented there-ore most recommendations for treatment are

ased on a consensus of opinion Despite this we

DIGORecommendations inChapter 11reventingDetecting andTreatingonadherence

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

gree with the KDIGO work group that thera-eutic lifestyle measures should be encour-ged Data regarding steroid therapy with-rawal and weight gain are controversial Aecent double-blind randomized controlled trialxamining early steroid therapy withdrawalid not show a difference in weight gain at 5ears posttransplant compared with the cohortemaining on standard maintenance corticoste-oid therapy62

DIGORecommendations inChapter 17ardiovascularManagement

171 Consider managing CVD at least as intensively inKTRs as in the general population with appropri-ate diagnostic tests and treatments (Not Graded)

172 We suggest using aspirin (65-100 mgd) in allpatients with atherosclerotic CVD unless there arecontraindications (2B)

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

his clearly deserves more attention becauseontrol of CVD has the potential to contributeore to long-term kidney graft survival than the

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

186 We suggest that patients with a history of skincancer be offered treatment with oral acitretin ifthere are no contraindications (2B)

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

There is a limited scientific basis for KDIGOuggestion recommendation 186 Although reti-oids now are used routinely in KTRs with aigh skin cancer burden our KDOQI work groupelieves that more data are needed before this

DOQIRationale andCommentary

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

exacerbated by immunosuppressionbull The therapies available for the can-

tions interfere with ability to admin-ister the standard chemotherapy

202 For patients with Kaposi sarcoma we suggestusing mTORi along with a reduction in overallimmunosuppression (2C)

DOQIRationale andCommentary

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

DIGORecommendations inChapter 11reventingDetecting andTreatingonadherence

111 Consider providing all KTRs and family memberswith education prevention and treatment mea-sures to minimize nonadherence to immunosup-pressive medications (Not Graded)

112 Consider providing KTRs at increased risk fornonadherence with increased levels of screeningfor nonadherence (Not Graded)

DOQIRationale andCommentary

Noncompliance or nonadherence to diet andedication is a common problem in KTRs Nonad-

erence to medication is associated with a high riskf acute rejection and allograft loss We agree thatarly efforts should be made to identify KTRs atncreased risk of nonadherence and that these pa-ients should be monitored closely Prevention iden-ification and treatment of nonadherence are inte-ral to the monitoring of kidney allograft functionnd long-term care of KTRs Certain subgroup ofTRs younger patients African Americans and

hose with financial hardships have an enhancedisk of nonadherence3233

In addition to identifying patients at risk it ismportant to have a system for addressing patientonadherence This requires coordinated efforts ofocial workers transplant coordinators financialounselors pharmacists primary nephrologists andhe patientrsquos family34 A combination of educa-ional behavioral and social support interventionsrovides the best results Because there is no per-ect measure of adherence consideration should beiven to multiple approaches for adherence moni-oring Similar team approaches also are importantn other areas requiring adherence such as dietxercise tobacco alcohol and drug use

DIGORecommendations inChapter 12accination

121 We recommend giving all KTRs approvedinactivated vaccines according to recommendedschedules for the general population except forHBV vaccination (1D)1211 We suggest HBV vaccination (ideally

prior to transplantation) and HBsAb titers6-12 weeks after completing the vaccina-

tion series (2D) h

12111 We suggest annual HBsAb[antibody to hepatitis B sur-face antigen] titers (2D)

12112 We suggest revaccination ifthe antibody titer falls below10 mIUmL (2D)

122 We suggest avoiding live vaccines in KTRs (2C)123 We suggest avoiding vaccinations except influ-

enza vaccination in the first 6 months followingkidney transplantation (2C)1231 We suggest resuming immunizations once

patients are receiving minimal mainte-nance doses of immunosuppressive medi-cations (2C)

1232 We recommend giving all KTRs whoare at least 1-month post-transplantinfluenza vaccination prior to the onsetof the annual influenza season regard-less of status of immunosuppression(1C)

124 We suggest giving the following vaccines to KTRswho due to age direct exposure residence ortravel to endemic areas or other epidemiologicalrisk factors are at increased risk for the specificdiseasesbull rabies (2D)bull tick-borne meningoencephalitis (2D)bull Japanese B encephalitismdashinactivated (2D)bull Meningococcus (2D)bull Pneumococcus (2D)bull Salmonella typhimdashinactivated (2D)1241 Consult an infectious disease specialist a

travel clinic or public health official forguidance on whether specific cases war-rant these vaccinations (Not Graded)

itis B antibody titers annually is a commonractice in the United States Hepatitis B is nots prevalent in the United States as in otherarts of the world and evidence supportingcreening in all patients posttransplant is lack-ng However screening for seroconversion inatients at risk (receiving a hepatitis B corentibodyndashpositive kidney) is appropriate Theseatients may benefit from lamivudine or ente-avir therapy36

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DIGORecommendations inChapter 13 Viraliseases

131 BK POLYOMA VIRUS1311 We suggest screening all KTRs for BKV

with quantitative plasma NAT (2C) atleastbull monthly for the first 3-6 months after

transplantation (2D)bull then every 3 months until the end of

the first post-transplant year (2D)bull whenever there is an unexplained rise

in serum creatinine (2D)bull and after treatment for acute rejection

(2D)1312 We suggest reducing immunosuppressive

medications when BKV plasma NAT is

persistently greater than 10 000 cop-iesmL (107 copiesL) (2D)

132 CYTOMEGALOVIRUS1321 CMV prophylaxis We recommend that

KTRs (except when donor and recipi-ent both have negative CMV serolo-gies) receive chemoprophylaxis forCMV infection with oral ganciclovir orvalganciclovir for at least 3 monthsafter transplantation (1B) and for 6weeks after treatment with a T-cellndashdepleting antibody (1C)

1322 In patients with CMV disease we suggestweekly monitoring of CMV by NAT orpp65 antigenemia (2D)

1323 CMV treatment13231 We recommend that all pa-

tients with serious (includ-ing most patients with tissueinvasive) CMV disease betreated with intravenousganciclovir (1D)

13233 We recommend that allCMV disease in pediatricKTRs be treated with intra-venous ganciclovir (1D)

13234 We suggest continuing therapyuntil CMV is no longer detect-able by plasma NAT or pp65antigenemia (2D)

1324 We suggest reducing immunosuppressivemedication in life-threatening CMV dis-ease and CMV disease that persists in theface of treatment until CMV disease hasresolved (2D)13241 We suggest monitoring graft

function closely during CMVdisease (2D)

133 EPSTEIN-BARR VIRUS AND POST-TRANS-PLANT LYMPHOPROLIFERATIVE DISEASE1331 We suggest monitoring high-risk (donor

1332 We suggest that EBV-seronegative pa-tients with an increasing EBV load haveimmunosuppressive medication reduced(2D)

1333 We recommend that patients with EBVdisease including PTLD have a reduc-tion or cessation of immunosuppres-sive medication (1C)

134 HERPES SIMPLEX VIRUS 1 2 AND VARI-CELLA ZOSTER VIRUS1341 We recommend that KTRs who de-

velop a superficial HSV 1 2 infectionbe treated (1B) with an appropriateoral antiviral agent (eg acyclovir vala-cyclovir or famciclovir) until all le-sions have resolved (1D)

1342 We recommend that KTRs with sys-temic HSV 1 2 infection be treated(1B) with intravenous acyclovir and areduction in immunosuppressive medi-cation (1D)13421 We recommend that intrave-

nous acyclovir continue un-til the patient has a clinicalresponse (1B) then switch toan appropriate oral antiviralagent (eg acyclovir valacy-clovir or famciclovir) to com-plete a total treatment durationof 14-21 days (2D)

1343 We suggest using a prophylactic antiviralagent for KTRs experiencing frequentrecurrences of HSV 12 infection (2D)

1344 We recommend that primary VZV infec-tion (chicken pox) in KTRs be treated(1C) with either intravenous or oral acy-clovir or valacyclovir and a temporaryreduction in amount of immunosuppres-sive medication (2D)

135 HEPATITIS C VIRUS1351 We suggest that HCV-infected KTRs be

treated only when the benefits of treat-ment clearly outweigh the risk of allo-graft rejection due to interferon-basedtherapy (eg fibrosing cholestatic hepati-tis life-threatening vasculitis) (2D)[Based on KDIGO Hepatitis C Recom-mendation 215]

1352 We suggest monotherapy with standardinterferon for HCV-infected KTRs inwhom the benefits of antiviral treatmentclearly outweigh the risks (2D) [Basedon KDIGO Hepatitis C Recommenda-tions 224 and 442]

1353 We suggest that all conventional currentinduction and maintenance immunosup-pressive regimens can be used in HCVinfected patients (2D) [Based on KDIGO

Hepatitis C Recommendation 43]

1355 Test HCV-infected patients at least every3-6 months for proteinuria (Not Graded)[Based on KDIGO Hepatitis C Recom-mendation 444]13551 For patients who develop new

onset proteinuria (either urineproteincreatinine ratio 1 or24-hour urine protein 1 g ontwo or more occasions) per-form an allograft biopsy withimmunofluorescence and elec-tron microscopy (Not Graded)[Based on KDIGO Hepatitis CRecommendation 444]

1356 We suggest that patients with HCV asso-ciated glomerulopathy not receive inter-feron (2D) [Based on KDIGO HepatitisC Recommendation 445]

136 HEPATITIS B VIRUS1361 We suggest that any currently available

induction and maintenance immunosup-pressive medication can be used in HBV-infected KTRs (2D)

1362 We suggest that interferon treatmentshould generally be avoided in HBVinfected KTRs (2C)

1363 We suggest that all HBsAg-positive KTRsreceive prophylaxis with tenofovir ente-cavir or lamivudine (2B)13631 Tenofovir or entecavir are pref-

erable to lamivudine to mini-mize development of potentialdrug resistance unless medica-tion cost requires that lami-vudinebe used (Not Graded)

13632 During therapy with antivi-rals measure HBV DNA andALT levels every 3 months tomonitor efficacy and to detectdrug resistance (Not Graded)

1364 We suggest treatment with adefovir ortenofovir for KTRs with lamivudine resis-tance (5 log10 copiesmL rebound ofHBV-DNA) (2D)

137 HUMAN IMMUNODEFICIENCY VIRUS1371 If not already done screen for HIV

infection (Not Graded)1372 To determine antiretroviral therapy refer

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

dults EBV-induced posttransplant lymphoprolif-rative disorder (PTLD) affects many more pediat-ic than adult KTRs If screening is someday to beoutinely implemented in US centers details regard-ng the best method of screening and levels ofiremia above which a clinical intervention should

HerpesandVaricella

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

Hepatitis C management posttransplant is ahallenge The KDIGO guidelines cited hereere based on the recently published KDIGOuideline for hepatitis C in CKD4 Hepatitis Cypically is not treated posttransplant because ofhe risk (50) of rejection precipitated bynterferon therapy particularly in US KTRs inhom hepatitis C commonly is genotype 1 which

s more resistant to treatment with interferon42

owever should hepatitis Cndashrelated glomerulo-ephritis develop the risk-benefit ratio may fa-or treatment in selected patients Such decisionslways should be made in consultation withepatology and infectious disease experts andhe transplant center Monitoring liver enzymeevels specifically alanine aminotransferaseALT) may reflect a change in hepatitis activityut monitoring hepatitis C viral load is not recom-ended because it does not seem to correlateith outcome Annual monitoring for hepatocel-

ular carcinoma using -fetoprotein and imagings encouraged but not often practiced

Hepatitis B

KDIGO recommendations for hepatitis B areeasonable and currently are followed in mostS centers except for recommendation 1366

hould be followed up by a hepatologist

Human ImmunodeficiencyVirus

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

2512 Include discussion of sexual activity and counsel-ing about contraception and safe sex practices infollow-up of adult KTRs (Not Graded)

2521 We suggest waiting for at least 1 year aftertransplantation before becoming pregnant andonly attempting pregnancy when kidney func-tion is stable with 1 gday proteinuria (2C)

2522 We recommend that MMF be discontinued orreplaced with azathioprine before pregnancyis attempted (1A)

2524 Counsel female KTRs with child-bearing poten-tial and their partners about fertility and preg-nancy as soon as possible after transplantation(Not Graded)

2525 Counsel pregnant KTRs and their partners aboutthe risks and benefits of breastfeeding (NotGraded)

2526 Refer pregnant patients to an obstetrician withexpertise in managing high-risk pregnancies(Not Graded)

2531 We suggest that male KTRs and their partners beadvised thatbull male fertility may improve after kidney trans-

plantation (2D)bull pregnancies fathered by KTRs appear to have

no more complications than those in thegeneral population (2D)

2532 We recommend that adult male KTRs beinformed of the possible risks of infertilityfrom mTORi (1C)25321 We suggest that adult male KTRs

who wish to maintain fertility shouldconsider avoiding mTORi or bank-ing sperm prior to mTORi use (2C)

DOQIRationale andCommentary

SexualDysfunction

Sexual dysfunction is a topic often over-ooked in clinic visits but one that manyatients want addressed Sexual dysfunctionas been reported in 30-60 of KTRs8586

FDA) and should be discontinued in women contem-lating pregnancy (Guideline 2522) Despite theame FDA rating for azathioprine there have beenears of experience with its use in pregnant KTRslthough it may be prudent to avoid sirolimus therapyuring pregnancy our work group was divided regard-ng KDIGO recommendation suggestion 2523 somef us agreed that mTOR-inhibitor therapy should betopped in pregnancy while others did not think thereas enough evidence to support this recommenda-

ion Until further data emerge regarding the safety ofTOR inhibitors in pregnancy this precaution must

e weighed against the risks and inconvenience ofhanging immunosuppression therapy All pregnantTRs are considered high-risk pregnancies and shoulde followed up by a high-risk obstetric team

Effect of SirolimusonSpermatogenesis

mTOR inhibitors can decrease testosterone levelsnd male fertility and we therefore concur that coun-eling males treated with this agent is importantKDIGO 2532) Implementation of this recommen-ation will require awareness on the part of the physi-ian when patients are switched to this drug because its used infrequently as an initial agent

KDOQI Commentary 27

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

itis B antibody titers annually is a commonractice in the United States Hepatitis B is nots prevalent in the United States as in otherarts of the world and evidence supportingcreening in all patients posttransplant is lack-ng However screening for seroconversion inatients at risk (receiving a hepatitis B corentibodyndashpositive kidney) is appropriate Theseatients may benefit from lamivudine or ente-avir therapy36

LiveVaccineandTimingofVaccine

There is no particular reason for a 6-monthag between transplant and vaccination Theheory is that vaccines are less likely to beffective in the period when immunosuppres-ion is high In the United States most individu-ls are on their baseline maintenance immuno-uppression therapy by 3 months posttransplantecisions regarding the timing of vaccines areade based on immunosuppression exposure

nd risk of infection Recipients also shouldvoid intimate contact with individuals whoave received live vaccines37 This includesvoiding close contact with children who haveeceived oral polio vaccine for 3 weeks anday include close contact with adults receiv-

ng the attenuated varicella vaccine to preventoster Immunosuppressed individuals are ad-ised to avoid contact for 7 days with individu-ls who have received live virus nasal spraysor influenza We concur with the recommenda-ion for flu vaccine but common practice inhe United States is to wait 3-6 months afterransplant before it is administered

DIGORecommendations inChapter 13 Viraliseases

131 BK POLYOMA VIRUS1311 We suggest screening all KTRs for BKV

with quantitative plasma NAT (2C) atleastbull monthly for the first 3-6 months after

transplantation (2D)bull then every 3 months until the end of

the first post-transplant year (2D)bull whenever there is an unexplained rise

in serum creatinine (2D)bull and after treatment for acute rejection

(2D)1312 We suggest reducing immunosuppressive

medications when BKV plasma NAT is

persistently greater than 10 000 cop-iesmL (107 copiesL) (2D)

132 CYTOMEGALOVIRUS1321 CMV prophylaxis We recommend that

KTRs (except when donor and recipi-ent both have negative CMV serolo-gies) receive chemoprophylaxis forCMV infection with oral ganciclovir orvalganciclovir for at least 3 monthsafter transplantation (1B) and for 6weeks after treatment with a T-cellndashdepleting antibody (1C)

1322 In patients with CMV disease we suggestweekly monitoring of CMV by NAT orpp65 antigenemia (2D)

1323 CMV treatment13231 We recommend that all pa-

tients with serious (includ-ing most patients with tissueinvasive) CMV disease betreated with intravenousganciclovir (1D)

13232 We recommend that CMVdisease in adult KTRs that isnot serious (eg episodes thatare associated with mildclinical symptoms) be treatedwith either intravenous gan-ciclovir or oral valganciclo-vir (1D)

13233 We recommend that allCMV disease in pediatricKTRs be treated with intra-venous ganciclovir (1D)

13234 We suggest continuing therapyuntil CMV is no longer detect-able by plasma NAT or pp65antigenemia (2D)

1324 We suggest reducing immunosuppressivemedication in life-threatening CMV dis-ease and CMV disease that persists in theface of treatment until CMV disease hasresolved (2D)13241 We suggest monitoring graft

function closely during CMVdisease (2D)

133 EPSTEIN-BARR VIRUS AND POST-TRANS-PLANT LYMPHOPROLIFERATIVE DISEASE1331 We suggest monitoring high-risk (donor

EBV seropositiverecipient seronegative)KTRs for EBV by NAT (2C)bull once in the first week after transplanta-

tion (2D)bull then at least monthly for the first 3-6

months after transplantation (2D)bull then every 3 months until the end of

the first post-transplant year (2D)bull and additionally after treatment for

acute rejection (2D)

1332 We suggest that EBV-seronegative pa-tients with an increasing EBV load haveimmunosuppressive medication reduced(2D)

1333 We recommend that patients with EBVdisease including PTLD have a reduc-tion or cessation of immunosuppres-sive medication (1C)

134 HERPES SIMPLEX VIRUS 1 2 AND VARI-CELLA ZOSTER VIRUS1341 We recommend that KTRs who de-

velop a superficial HSV 1 2 infectionbe treated (1B) with an appropriateoral antiviral agent (eg acyclovir vala-cyclovir or famciclovir) until all le-sions have resolved (1D)

1342 We recommend that KTRs with sys-temic HSV 1 2 infection be treated(1B) with intravenous acyclovir and areduction in immunosuppressive medi-cation (1D)13421 We recommend that intrave-

nous acyclovir continue un-til the patient has a clinicalresponse (1B) then switch toan appropriate oral antiviralagent (eg acyclovir valacy-clovir or famciclovir) to com-plete a total treatment durationof 14-21 days (2D)

1343 We suggest using a prophylactic antiviralagent for KTRs experiencing frequentrecurrences of HSV 12 infection (2D)

1344 We recommend that primary VZV infec-tion (chicken pox) in KTRs be treated(1C) with either intravenous or oral acy-clovir or valacyclovir and a temporaryreduction in amount of immunosuppres-sive medication (2D)

135 HEPATITIS C VIRUS1351 We suggest that HCV-infected KTRs be

treated only when the benefits of treat-ment clearly outweigh the risk of allo-graft rejection due to interferon-basedtherapy (eg fibrosing cholestatic hepati-tis life-threatening vasculitis) (2D)[Based on KDIGO Hepatitis C Recom-mendation 215]

1352 We suggest monotherapy with standardinterferon for HCV-infected KTRs inwhom the benefits of antiviral treatmentclearly outweigh the risks (2D) [Basedon KDIGO Hepatitis C Recommenda-tions 224 and 442]

1353 We suggest that all conventional currentinduction and maintenance immunosup-pressive regimens can be used in HCVinfected patients (2D) [Based on KDIGO

Hepatitis C Recommendation 43]

1354 Measure ALT in HCV-infected patientsmonthly for the first 6 months and every3-6 months thereafter Perform imagingannually to look for cirrhosis and hepato-cellular carcinoma (Not Graded) [Basedon KDIGO Hepatitis C Recommendation441] (See Recommendation 193)

1355 Test HCV-infected patients at least every3-6 months for proteinuria (Not Graded)[Based on KDIGO Hepatitis C Recom-mendation 444]13551 For patients who develop new

onset proteinuria (either urineproteincreatinine ratio 1 or24-hour urine protein 1 g ontwo or more occasions) per-form an allograft biopsy withimmunofluorescence and elec-tron microscopy (Not Graded)[Based on KDIGO Hepatitis CRecommendation 444]

1356 We suggest that patients with HCV asso-ciated glomerulopathy not receive inter-feron (2D) [Based on KDIGO HepatitisC Recommendation 445]

136 HEPATITIS B VIRUS1361 We suggest that any currently available

induction and maintenance immunosup-pressive medication can be used in HBV-infected KTRs (2D)

1362 We suggest that interferon treatmentshould generally be avoided in HBVinfected KTRs (2C)

1363 We suggest that all HBsAg-positive KTRsreceive prophylaxis with tenofovir ente-cavir or lamivudine (2B)13631 Tenofovir or entecavir are pref-

infection (Not Graded)1372 To determine antiretroviral therapy refer

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

HerpesandVaricella

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

Hepatitis C management posttransplant is ahallenge The KDIGO guidelines cited hereere based on the recently published KDIGOuideline for hepatitis C in CKD4 Hepatitis Cypically is not treated posttransplant because ofhe risk (50) of rejection precipitated bynterferon therapy particularly in US KTRs inhom hepatitis C commonly is genotype 1 which

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

infection (Not Graded)1372 To determine antiretroviral therapy refer

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

dults EBV-induced posttransplant lymphoprolif-rative disorder (PTLD) affects many more pediat-ic than adult KTRs If screening is someday to beoutinely implemented in US centers details regard-ng the best method of screening and levels ofiremia above which a clinical intervention should

HerpesandVaricella

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

Hepatitis C management posttransplant is ahallenge The KDIGO guidelines cited hereere based on the recently published KDIGOuideline for hepatitis C in CKD4 Hepatitis Cypically is not treated posttransplant because ofhe risk (50) of rejection precipitated bynterferon therapy particularly in US KTRs inhom hepatitis C commonly is genotype 1 which

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

137 HUMAN IMMUNODEFICIENCY VIRUS1371 If not already done screen for HIV

infection (Not Graded)1372 To determine antiretroviral therapy refer

HIV-infected KTRs to an HIV specialistwho should pay special attention to drugndashdrug interactions and appropriate dosingof medications (Not Graded)

DOQIRationale andCommentary

Viral infections are particularly problematic inransplant recipients because of the preferentialnhibition of T-lymphocyte function by both induc-ion and maintenance immunosuppression Use ofnduction immunosuppression with lymphocyte-epleting agents (thymoglobulin or alemtuzumab)s associated with a greater risk of viral infectionosttransplant In general the greater the cumula-ive exposure to immunosuppression the greaterhe risk of infectious complications The presenta-ion of viral infections can be asymptomatic vaguend nonspecific or life-threatening acute illnessany viral infections seen in KTRs are rarely seen

n immunocompetent patients and therefore do notnter into the differential diagnosis for physiciansnfamiliar with transplant recipients Close commu-ication with the transplant center is crucial inaring for the transplant population Early detectionnd institution of therapy provide the best chanceor viral eradication

BKVirus

Although the work group agreed with KDIGOuggestions for BK virus screening posttransplante did not think it was practical to require screen-

ng exclusively with quantitative plasma nucleiccid testing (NAT) because many US centers usenitial urinary screening and then test plasma onlyf urine screening results are positive Howeverhere is no disagreement that some type of screen-ng for BK virus is critical to avoid BK nephropa-hy for which there is no specific treatment when its established Complicating screening for BK vi-us is the variability in results between laboratoriesnd uncertainty about the level of viremia thathould trigger a response to decrease in immunosup-ression In the presence of viremia and increase inerum creatinine level a renal allograft biopsy isndicated to confirm the presence of BK nephropa-

hy Because BK viremia and viruria certainly can b

e detected beyond the first year it is not clear howong screening should be continued posttransplantlthough most centers screen for the first year onlyngoing clinical trials are exploring effective treat-ent for BK nephropathy3839 Decisions about

ecreases in immunosuppression currently theainstay of BK viremia management always

hould be made in consultation with the transplantenter

Cytomegalovirus

KDIGO recommendation 1321 regarding cyto-egalovirus (CMV) prophylaxis is reasonable and

pplicable to the US population Universal prophy-axis for CMV now is recommended over initiatingre-emptive treatment after CMV develops40 Aajor concern for US patients is the cost of CMV

rophylaxis with oral valgancyclovir Leukopeniaan be observed in patients using mycophenolatereparations when prophylaxis with valgancyclo-ir is used Screening for CMV is best performedsing NAT methods (1322) CMV antigenemiassays are still in use in many facilities but are nots sensitive as PCR assays41 There is no utility inhecking for serologic response to CMV with IgGr IgM titers posttransplant because the immuneesponse is not predictable Patients with CMVisease should be cared for by clinicians familiarith treating this disease It is recommended that

reatment be continued until viral load is undetect-ble followed by prophylactic doses of valgancy-lovir for an additional 3 months35

Epstein-BarrVirus

Current practice regarding EBV screening variesmong centers in the United States and many doot routinely screen for EBV posttransplant evenn recipient-negative donor-positive cases In con-rast to KDIGO recommendation 1311 routineBV screening is not recommended in AST infec-

ious disease guidelines35 In many centers EBVcreening is reserved for children who are muchore commonly EBV negative pretransplant than

dults EBV-induced posttransplant lymphoprolif-rative disorder (PTLD) affects many more pediat-ic than adult KTRs If screening is someday to beoutinely implemented in US centers details regard-ng the best method of screening and levels ofiremia above which a clinical intervention should

HerpesandVaricella

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

Hepatitis C management posttransplant is ahallenge The KDIGO guidelines cited hereere based on the recently published KDIGOuideline for hepatitis C in CKD4 Hepatitis Cypically is not treated posttransplant because ofhe risk (50) of rejection precipitated bynterferon therapy particularly in US KTRs inhom hepatitis C commonly is genotype 1 which

s more resistant to treatment with interferon42

owever should hepatitis Cndashrelated glomerulo-ephritis develop the risk-benefit ratio may fa-or treatment in selected patients Such decisionslways should be made in consultation withepatology and infectious disease experts andhe transplant center Monitoring liver enzymeevels specifically alanine aminotransferaseALT) may reflect a change in hepatitis activityut monitoring hepatitis C viral load is not recom-ended because it does not seem to correlateith outcome Annual monitoring for hepatocel-

ular carcinoma using -fetoprotein and imagings encouraged but not often practiced

Hepatitis B

KDIGO recommendations for hepatitis B areeasonable and currently are followed in mostS centers except for recommendation 1366

see previous recommendation under vaccina-ions) KTRs with hepatitis C or hepatitis B also

hould be followed up by a hepatologist

Human ImmunodeficiencyVirus

Human immunodeficiency virus (HIV)-posi-ive individuals are now acceptable for transplantf CD4 count is 200 cellsL and viral loadVL) is undetectable3543 Transplant should beerformed at centers with expertise in managingIV-positive individuals and care should be co-rdinated carefully with HIV specialists Somentiretroviral agents in particular the proteasenhibitors have potentially serious drug interac-ions with immunosuppressive agents35

DOQIRationale andCommentary

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

treatment of infection posttransplant

DOQIRationale andCommentary

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

Dyslipidemia

The KDIGO work group based their recom-endations for evaluation and treatment of

yperlipidemia on the KDOQI dyslipidemiauidelines for KTRs60 We agree with theseecommendations CNIs potentiate the toxicityf statins by slowing their metabolism throughhe cytochrome P-450 system This interactionccurs more commonly with cyclosporine61

han with tacrolimus Dyslipidemia especiallyypertriglyceridemia frequently complicatesTOR-inhibitor use and lipid-lowering therapy

s required in most patients using these agents

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

DIGORecommendations inChapter 17ardiovascularManagement

171 Consider managing CVD at least as intensively inKTRs as in the general population with appropri-ate diagnostic tests and treatments (Not Graded)

172 We suggest using aspirin (65-100 mgd) in allpatients with atherosclerotic CVD unless there arecontraindications (2B)

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

his clearly deserves more attention becauseontrol of CVD has the potential to contributeore to long-term kidney graft survival than the

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

HerpesandVaricella

Systemic herpesvirus infections can be lifehreatening in transplant recipients and should bereated aggressively with intravenous antiviralgents as described in the KDIGO recommenda-ions Less aggressive cutaneous infection can bereated with oral antiviral agents as outlined inhe KDIGO guidelines

Varicella exposure is particularly concerning inransplant recipients The work group disputes theecommended dosing of acyclovir for varicellaxposure Acyclovir at a dose of 10 mgkg or about00 mg 4 times daily of oral acyclovir would betandard dosing We agree with the use of varicellammune globulin and emphasize the need to avoidhe varicella vaccine because it is a live virushould a transplant recipient develop a systemicaricella infection hospitalization and high-dosentravenous acyclovir therapy are warranted

Hepatitis C

Hepatitis C management posttransplant is ahallenge The KDIGO guidelines cited hereere based on the recently published KDIGOuideline for hepatitis C in CKD4 Hepatitis Cypically is not treated posttransplant because ofhe risk (50) of rejection precipitated bynterferon therapy particularly in US KTRs inhom hepatitis C commonly is genotype 1 which

s more resistant to treatment with interferon42

ular carcinoma using -fetoprotein and imagings encouraged but not often practiced

Hepatitis B

KDIGO recommendations for hepatitis B areeasonable and currently are followed in mostS centers except for recommendation 1366

see previous recommendation under vaccina-ions) KTRs with hepatitis C or hepatitis B also

hould be followed up by a hepatologist

Human ImmunodeficiencyVirus

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

treatment of infection posttransplant

DOQIRationale andCommentary

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

Hypertension

The KDIGO work group adapted the KDOQI004 recommendations for target blood pres-ure in KTRs55 Self measurement is useful inssessing response to therapy and enhancesdherence56 In general we agree that the classf antihypertensive agent does not matter inhe treatment of blood pressure elevation inhis population and that attention should beiven to potential side effects of antihyperten-ive agents as well as possible interactionsith the immunosuppressive regimen (eg non-ihydropyridine calcium channel blockers andNIs) In the absence of adequate randomizedontrolled trials it is not known whether angio-ensin-converting enzyme (ACE) inhibitors andngiotensin receptor blockers (ARBs) prolongecipient or allograft survival Some but notll retrospective studies suggest a benefitowever all these studies are limited by selec-ion bias5758 Although ACE inhibitors andRBs commonly lead to some decrease inFR treatment with these drugs should be

Dyslipidemia

The KDIGO work group based their recom-endations for evaluation and treatment of

yperlipidemia on the KDOQI dyslipidemiauidelines for KTRs60 We agree with theseecommendations CNIs potentiate the toxicityf statins by slowing their metabolism throughhe cytochrome P-450 system This interactionccurs more commonly with cyclosporine61

han with tacrolimus Dyslipidemia especiallyypertriglyceridemia frequently complicatesTOR-inhibitor use and lipid-lowering therapy

s required in most patients using these agents

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

gree with the KDIGO work group that thera-eutic lifestyle measures should be encour-ged Data regarding steroid therapy with-rawal and weight gain are controversial Aecent double-blind randomized controlled trialxamining early steroid therapy withdrawalid not show a difference in weight gain at 5ears posttransplant compared with the cohortemaining on standard maintenance corticoste-oid therapy62

DIGORecommendations inChapter 17ardiovascularManagement

171 Consider managing CVD at least as intensively inKTRs as in the general population with appropri-ate diagnostic tests and treatments (Not Graded)

172 We suggest using aspirin (65-100 mgd) in allpatients with atherosclerotic CVD unless there arecontraindications (2B)

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

his clearly deserves more attention becauseontrol of CVD has the potential to contributeore to long-term kidney graft survival than the

iscovery of newer drugs that decrease the ratef allograft rejection Our KDOQI working groupgreed with the use of low-dose aspirin in KTRs

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

186 We suggest that patients with a history of skincancer be offered treatment with oral acitretin ifthere are no contraindications (2B)

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

There is a limited scientific basis for KDIGOuggestion recommendation 186 Although reti-oids now are used routinely in KTRs with aigh skin cancer burden our KDOQI work groupelieves that more data are needed before this

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

creening recommendation Based on a recentuestionnaire of US gastroenterologists only 50creen patients for hepatocellular carcinoma70

herefore implementation of this guideline byS clinicians is unlikely to be widespread

cer (2C)

2011 Important factors for consideration in-clude (Not Graded)bull The stage of cancer at diagnosisbull Whether the cancer is likely to be

exacerbated by immunosuppressionbull The therapies available for the can-

202 For patients with Kaposi sarcoma we suggestusing mTORi along with a reduction in overallimmunosuppression (2C)

DOQIRationale andCommentary

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

UrinaryTract Infection

Urinary tract infections (UTIs) after kidneyransplant are very common and account for aarge percentage of readmissions posttransplantTIs are common because of multiple factors

ncluding the disrupted anatomy of the urinaryract with a ureteroneocystotomy incompleteladder emptying because of diabetes or pros-atic hypertrophy and impaired immune re-ponses Prophylaxis of UTIs usually is under-aken with trimethoprim-sulfamethoxazole for 6onths posttransplant although infections often

ccur despite therapy because of the develop-ent of drug resistance Although native kidney

yelonephritis does not always require hospital-zation it is recommended that all KTRs withhis diagnosis be hospitalized because the graftysfunction that usually accompanies transplantyelonephritis requires aggressive investigationnd treatment Individuals with recurrent UTIsarrant evaluation with urologic assessment Pa-

ients with recurrent UTIs may benefit fromong-term suppressive therapy

Pneumocystic Pneumonia

We agree that Pneumocystis jirovecii pneumoniaPCP) prophylaxis is important for the first 3-6onths posttransplant (1421)After the first month

very-other-day dosing of trimethoprim-sulfame-hoxazole or atovaquone is believed to be adequaterophylaxis In cases in which neither of thesegents can be used an individual may be treatedrophylactically with inhaled pentamidine OurDOQI work group emphasized that patients whoevelop PCP should be transferred to the transplantenter promptly for management and adjustmentsn immunosuppression

Tuberculosis

Monitoring for latent tuberculosis has posed a

hallenge in the immunosuppressed population be-

ause of the unreliable nature of skin testing Newerechniques involving interferon release assays aremerging as the new gold standard for detection ofatent tuberculosis4445

CandidaProphylaxis

Oral candidiasis must be screened for usingral mucosa examination on follow-up visitsn KTRs This is especially true in the earlyosttransplant period when immunosuppres-ive medication dosage is the highest Wegree with these recommendations and empha-ize that if fluconazole is used there is aotential for serious drug interactions becausef cytochrome P-450 3A4 inhibition

SUMMARY OF COMMENTARY ON SECTION IIGRAFT MONITORING AND INFECTIONS

Improvement in short-term outcomes has not trans-lated into significant improvements in long-term out-comes in KTRs The lack of significant improvement inlong-term survival may be related to post-transplantcomplications Frequent posttransplant monitoring mayimprove long-term outcomes by decreasing chronic graftfailure or death with a functioning graft Our work groupconcurred with the recommendation and schedules ofroutine screening in monitoring kidney allograft functionafter kidney transplant with a low threshold for perform-ing kidney biopsy in cases of graft dysfunction or protein-uria Expert tissue processing and interpretation of trans-plant biopsy specimens by pathologists with transplantexperience are critical Regular surveillance of the pa-tientrsquos kidney function at the transplant center or in thenephrologistrsquos office offers an opportunity to enhancepatient adherence to medication diet and healthy life-style Although CKD in KTRs progresses more slowlythan CKD in other patients the work group agreed thatthe KDIGO guidelines on CKD should be followed inKTRs

Opportunistic infections are common in KTRs al-though advances in diagnosis and treatment have led toimproved survival in KTRs with infection It is nowstandard of care to use vaccinations in KTRs as long asthe vaccine does not contain live or attenuated virus Italso is routine to screen for or use prophylaxis to preventseveral posttransplant viral infections With few excep-tions (related to EBV and BK virus screening andhepatitis B vaccination posttransplant) we concurredwith KDIGO guidelines for vaccination screening and

treatment of infection posttransplant

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

his clearly deserves more attention becauseontrol of CVD has the potential to contributeore to long-term kidney graft survival than the

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

2163 There are insufficient data to guide treat-ment after the first 12 months (NotGraded)

217 In patients with CKD stages 4ndash5T we suggest thatBMD testing not be performed routinely becauseBMD does not predict fracture risk as it does in thegeneral population and BMD does not predict thetype of kidney transplant bone disease (2B)

218 In patients with CKD stages 4ndash5T with a knownlow BMD we suggest management as for patientswith CKD stages 4-5 not on dialysis (2C)

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

SexualDysfunction

Sexual dysfunction is a topic often over-ooked in clinic visits but one that manyatients want addressed Sexual dysfunctionas been reported in 30-60 of KTRs8586

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

152 Managing NODAT or Diabetes Present at Trans-plantation1521 If NODAT develops consider modifying

the immunosuppressive drug regimen toreverse or ameliorate diabetes afterweighing the risk of rejection and otherpotential adverse effects (Not Graded)

1522 Consider targeting HbA1c 70-75and avoid targeting HbA1c 60 espe-cially if hypoglycemic reactions are com-mon (Not Graded)

1523 We suggest that in patients with diabetesaspirin (65-100 mgd) use for the primaryprevention of CVD be based on patientpreferences and values balancing the riskfor ischemic events to that of bleeding(2D)

DOQIRationale andCommentary

Diabetic Screening

We agree with screening for new-onset diabetesfter transplantation (NODAT) as outlined by theDIGO work group Definitions used are similar

o those of the American Diabetes AssociationADA) The greater frequency of testing initially isustified by the high risk of NODAT in the earlyosttransplant period however ongoing screenings required because the risk of the development ofODAT continues to increase over time4647 We

lso point out that prediabetic states (impairedasting glucose level and impaired glucose toler-nce) occur even more commonly than overt diabe-es48 and may be associated with metabolic syn-rome as well as with increased cardiovascular

ortality49-51 Potential implications of these predia-

etic states emphasize the importance of perform-ng blood tests under fasting conditions For pa-ients with fasting hyperglycemia an oral glucoseolerance test or hemoglobinA1c (HbA1c) test shoulde performed Although more cumbersome to per-orm data suggest that an oral glucose toleranceest is a more sensitive indicator of NODAT inyperglycemic KTRs52 This may allow earlieretection of overt diabetes and more prompt institu-ion of treatment

DiabetesManagement

Data supporting a substantial benefit in themelioration or reversal of NODAT using immu-osuppression modification in KTRs are veryimited There was consensus in our work grouphat considering the paucity of data for reversingODAT by changing immunosuppression and

he potential risk of an adverse outcome withuch a maneuver KDIGO suggestion 1521 couldot be supported Certainly if such a step waseing considered it should be done in conjunc-ion with the transplant center Targeting an HbA1c

evel of 7-75 and avoiding levels 6 isased on data showing increased cardiovascularvents with the lower HbA1c target5354

Hypertension

The KDIGO work group adapted the KDOQI004 recommendations for target blood pres-ure in KTRs55 Self measurement is useful inssessing response to therapy and enhancesdherence56 In general we agree that the classf antihypertensive agent does not matter inhe treatment of blood pressure elevation inhis population and that attention should beiven to potential side effects of antihyperten-ive agents as well as possible interactionsith the immunosuppressive regimen (eg non-ihydropyridine calcium channel blockers andNIs) In the absence of adequate randomizedontrolled trials it is not known whether angio-ensin-converting enzyme (ACE) inhibitors andngiotensin receptor blockers (ARBs) prolongecipient or allograft survival Some but notll retrospective studies suggest a benefitowever all these studies are limited by selec-ion bias5758 Although ACE inhibitors andRBs commonly lead to some decrease inFR treatment with these drugs should be

ontinued unless serum creatinine level in-reases by 25 to 30 in keeping withDOQI recommendations55 In KTRs receiv-

Dyslipidemia

The KDIGO work group based their recom-endations for evaluation and treatment of

yperlipidemia on the KDOQI dyslipidemiauidelines for KTRs60 We agree with theseecommendations CNIs potentiate the toxicityf statins by slowing their metabolism throughhe cytochrome P-450 system This interactionccurs more commonly with cyclosporine61

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

171 Consider managing CVD at least as intensively inKTRs as in the general population with appropri-ate diagnostic tests and treatments (Not Graded)

172 We suggest using aspirin (65-100 mgd) in allpatients with atherosclerotic CVD unless there arecontraindications (2B)

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

There is a limited scientific basis for KDIGOuggestion recommendation 186 Although reti-oids now are used routinely in KTRs with aigh skin cancer burden our KDOQI work groupelieves that more data are needed before this

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

Hypertension

The KDIGO work group adapted the KDOQI004 recommendations for target blood pres-ure in KTRs55 Self measurement is useful inssessing response to therapy and enhancesdherence56 In general we agree that the classf antihypertensive agent does not matter inhe treatment of blood pressure elevation inhis population and that attention should beiven to potential side effects of antihyperten-ive agents as well as possible interactionsith the immunosuppressive regimen (eg non-ihydropyridine calcium channel blockers andNIs) In the absence of adequate randomizedontrolled trials it is not known whether angio-ensin-converting enzyme (ACE) inhibitors andngiotensin receptor blockers (ARBs) prolongecipient or allograft survival Some but notll retrospective studies suggest a benefitowever all these studies are limited by selec-ion bias5758 Although ACE inhibitors andRBs commonly lead to some decrease inFR treatment with these drugs should be

Dyslipidemia

The KDIGO work group based their recom-endations for evaluation and treatment of

yperlipidemia on the KDOQI dyslipidemiauidelines for KTRs60 We agree with theseecommendations CNIs potentiate the toxicityf statins by slowing their metabolism throughhe cytochrome P-450 system This interactionccurs more commonly with cyclosporine61

han with tacrolimus Dyslipidemia especiallyypertriglyceridemia frequently complicatesTOR-inhibitor use and lipid-lowering therapy

s required in most patients using these agents

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

gree with the KDIGO work group that thera-eutic lifestyle measures should be encour-ged Data regarding steroid therapy with-rawal and weight gain are controversial Aecent double-blind randomized controlled trialxamining early steroid therapy withdrawalid not show a difference in weight gain at 5ears posttransplant compared with the cohortemaining on standard maintenance corticoste-oid therapy62

DIGORecommendations inChapter 17ardiovascularManagement

171 Consider managing CVD at least as intensively inKTRs as in the general population with appropri-ate diagnostic tests and treatments (Not Graded)

172 We suggest using aspirin (65-100 mgd) in allpatients with atherosclerotic CVD unless there arecontraindications (2B)

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

his clearly deserves more attention becauseontrol of CVD has the potential to contributeore to long-term kidney graft survival than the

iscovery of newer drugs that decrease the ratef allograft rejection Our KDOQI working groupgreed with the use of low-dose aspirin in KTRs

SUMMARY OF COMMENTARY ONSECTION III CVD

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

(2D) s

186 We suggest that patients with a history of skincancer be offered treatment with oral acitretin ifthere are no contraindications (2B)

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

There is a limited scientific basis for KDIGOuggestion recommendation 186 Although reti-oids now are used routinely in KTRs with aigh skin cancer burden our KDOQI work groupelieves that more data are needed before this

uggestion should be accepted as a guideline In

DOQIRationale andCommentary

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

creening recommendation Based on a recentuestionnaire of US gastroenterologists only 50creen patients for hepatocellular carcinoma70

herefore implementation of this guideline byS clinicians is unlikely to be widespread

DIGORecommendations inChapter 20anagingCancerwithReductionof

201 We suggest consideration be given to reducingimmunosuppressive medications for KTRs with can-

cer (2C)

2011 Important factors for consideration in-clude (Not Graded)bull The stage of cancer at diagnosisbull Whether the cancer is likely to be

exacerbated by immunosuppressionbull The therapies available for the can-

cerbull Whether immunosuppressive medica-

tions interfere with ability to admin-ister the standard chemotherapy

202 For patients with Kaposi sarcoma we suggestusing mTORi along with a reduction in overallimmunosuppression (2C)

DOQIRationale andCommentary

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

2122 In CKD patients receiving treatments forCKDndashMBD or in whom biochemicalabnormalities are identified it is reason-able to increase the frequency of measure-ments to monitor for efficacy and sideeffects (Not Graded)

2123 It is reasonable to manage these abnor-malities as for patients with CKD stages3-5 (Not Graded)

213 In patients with CKD stages 1ndash5T we suggest that25(OH)D (calcidiol) levels might be measuredand repeated testing determined by baseline valuesand interventions (2C)

214 In patients with CKD stages 1ndash5T we suggest thatvitamin D deficiency and insufficiency be cor-rected using treatment strategies recommended forthe general population (2C)

215 In patients with an eGFR greater than approxi-mately 30 mLmin173 m2 we suggest measuringBMD in the first 3 months after kidney transplantif they receive corticosteroids or have risk factorsfor osteoporosis as in the general population (2D)

2163 There are insufficient data to guide treat-ment after the first 12 months (NotGraded)

217 In patients with CKD stages 4ndash5T we suggest thatBMD testing not be performed routinely becauseBMD does not predict fracture risk as it does in thegeneral population and BMD does not predict thetype of kidney transplant bone disease (2B)

218 In patients with CKD stages 4ndash5T with a knownlow BMD we suggest management as for patientswith CKD stages 4-5 not on dialysis (2C)

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

Dyslipidemia

The KDIGO work group based their recom-endations for evaluation and treatment of

TobaccoUse

Not surprisingly tobacco use at the time ofransplant is associated with decreased patientnd graft survival as well as increased risk ofosttransplant cardiovascular disease (CVD)lthough the KDIGO work group recom-ends initial screening and intervention dur-

ng the hospitalization for transplant we be-ieve there may be benefit gained by startingounseling in the pretransplant period duringhe evaluation phase Unfortunately this doesot occur often because of time and personnelonstraints in transplant centers Ideally allransplant centers should have smoking-cessa-ion programs available to patients either in-ouse or through referral Ideally systemshould be created to continue to screen andonitor for smoking cessation at yearly inter-

als after transplant because there is a highate of relapse with this addiction As outlinedn KDIGO Table 253 although all pharmaco-ogic therapies for smoking cessation can besed in KTRs the starting dose of vareniclinehould be decreased in patients with GFR 30Lmin

Obesity

Obesity is an epidemic in the United Statesnd the proportion of obese kidney transplantandidates continues to grow In additioneight gain after transplant is very commonly

bserved Obesity in KTRs is associated with w

ncreased risks of wound complications de-ayed graft function acute rejection and NO-AT resulting in inferior patient and graftutcomes Attention to this potential complica-ion and counseling should be initiated duringhe pretransplant evaluation phase Informa-ion regarding pharmacologic therapies foreight loss in KTRs is not available and we

gree with the KDIGO work group that thera-eutic lifestyle measures should be encour-ged Data regarding steroid therapy with-rawal and weight gain are controversial Aecent double-blind randomized controlled trialxamining early steroid therapy withdrawalid not show a difference in weight gain at 5ears posttransplant compared with the cohortemaining on standard maintenance corticoste-oid therapy62

DIGORecommendations inChapter 17ardiovascularManagement

171 Consider managing CVD at least as intensively inKTRs as in the general population with appropri-ate diagnostic tests and treatments (Not Graded)

172 We suggest using aspirin (65-100 mgd) in allpatients with atherosclerotic CVD unless there arecontraindications (2B)

DOQIRationale andCommentary

Although outcomes are favorable comparedith remaining on the waiting list the risk of

ardiovascular mortality in KTRs is several-foldigher than observed in the general population63

specially in younger age groups and patientsith decreasing allograft function64 CVD is aajor cause of graft loss after the first post-

ransplant year In this context we strongly agreehat CVD should be managed in KTRs at least asntensively as in the general population Ideallyecreasing CVD risk in KTRs requires a multifac-ted and multidisciplinary approach Based onurrent practice models in the United States theransplant and nephrology community has notet been able to achieve these desirable goals65

his clearly deserves more attention becauseontrol of CVD has the potential to contributeore to long-term kidney graft survival than the

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

186 We suggest that patients with a history of skincancer be offered treatment with oral acitretin ifthere are no contraindications (2B)

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

There is a limited scientific basis for KDIGOuggestion recommendation 186 Although reti-oids now are used routinely in KTRs with aigh skin cancer burden our KDOQI work groupelieves that more data are needed before this

uggestion should be accepted as a guideline In

DOQIRationale andCommentary

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

SUMMARY OF COMMENTARY ONSECTION III CVD

COMMENTARY ON SECTION IV OF KDIGO

TRANSPLANT GUIDELINE MALIGNANCY

DIGORecommendations inChapter 18 Cancerf the Skin andLip

181 We recommend that KTRs especially thosewho have fair skin live in high sun-exposureclimates have occupations requiring sun expo-sure have had significant sun exposure as achild or have a history of skin cancer be toldthat their risk of skin and lip cancer is veryhigh (1C)

182 We recommend that KTRs minimize life-longsun exposure and use appropriate ultravioletlight blocking agents (1D)

183 We suggest that adult KTRs perform skin andlip self-examinations and report new lesions toa health-care provider (2D)

184 For adult KTRs we suggest that a qualified healthprofessional with experience in diagnosing skincancer perform annual skin and lip examinationon KTRs except possibly for KTRs with dark skinpigmentation (2D)

185 We suggest that patients with a history of skin orlip cancer or premalignant lesions be referred to andfollowed by a qualified health professional withexperience in diagnosing and treating skin cancer

With the decrease in acute rejection during the pastdecade in association with improved immunosuppres-sion regimens patient death now rivals chronic graftdysfunction as one of the leading causes of long-termgraft loss Because CVD is the most common cause ofpatient death in KTRs a concerted effort at minimizingrisk factors for heart disease likely will have as great oreven greater impact on optimizing patient and graftoutcomes than the discovery of new antirejection thera-pies CVD risk reduction strategies should include regularscreening for new-onset diabetes (using ADA-based defini-tions) in the posttransplant period in previously nondiabeticpatients good glycemic regulation for diabetic patients accord-ing to current ADA guidelines and lipid management andblood pressure control according to KDOQI recommenda-tions In addition promotion of a healthy lifestyle throughweight control exercise and smoking cessation should be acentral part of posttransplant counseling and care Whenimmunosuppression modification is being considered to miti-gate cardiovascular risk we recommend that this be inconjunction with the transplant center In summary we gener-ally concurred with the suggestions of the work group in thissection but based on current practice standards in the UnitedStateschallengesremainwith implementationof thisguideline

186 We suggest that patients with a history of skincancer be offered treatment with oral acitretin ifthere are no contraindications (2B)

DOQIRationale andCommentary

CounselingandSunscreen

We concur with recommendations 181 and82 because skin cancer is a major source oforbidity and sometimes mortality in KTRsarning patients at risk of the high danger of

kin cancer a 1C recommendation is reinforcedy a recent prospective case-control study ofrgan transplant recipients that showed that regu-ar use of broad-spectrum sunscreens that pro-ide UVA and UVB protection may prevent theevelopment of actinic keratosis invasive squa-ous cell carcinoma and to a lesser extent

asal cell carcinoma66 Most cancer-causing ra-iation is thought to come from the UVB spec-rum and newer broad-spectrum sunscreens pro-ide protection against UVA and UVB radiationounseling about sunscreen and the need for sunvoidance needs to be incorporated into routineffice visits although it may not always beuccessful In a recent study of KTRs in which1 of patients had been informed about theeed for sun protection only 46 used morehan a tube of sunscreen per year67

Dermatology Involvement

There is increased evidence to suggest thatpecialty dermatology clinics for organ trans-lant recipients improve outcome measures in-luding compliance with photoprotection andncreased awareness of skin cancer68 The re-ources required for these specialty clinics makemplementation difficult for community nephrol-gy groups that do not have direct access to aransplant center Transplant patients should bencouraged to have annual visits with their trans-lant center and if dermatology specialty clinicsre available attempt to coordinate a skin cancervaluation annually

UseofRetinoid-likeCompounds

There is a limited scientific basis for KDIGOuggestion recommendation 186 Although reti-oids now are used routinely in KTRs with aigh skin cancer burden our KDOQI work groupelieves that more data are needed before this

uggestion should be accepted as a guideline In

191 Develop an individualized screening plan for eachKTR that takes into account the patientrsquos pastmedical and family history tobacco use compet-ing risks for death and the performance of thescreening methodology (Not Graded)

192 Screen for the following cancers as per localguidelines for the general population (Not Graded)Women cervical breast and colon cancer Menprostate and colon cancer

DOQIRationale andCommentary

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

creening recommendation Based on a recentuestionnaire of US gastroenterologists only 50creen patients for hepatocellular carcinoma70

herefore implementation of this guideline byS clinicians is unlikely to be widespread

DIGORecommendations inChapter 20anagingCancerwithReductionof

mmunosuppressiveMedication

201 We suggest consideration be given to reducingimmunosuppressive medications for KTRs with can-

cer (2C)

2011 Important factors for consideration in-clude (Not Graded)bull The stage of cancer at diagnosisbull Whether the cancer is likely to be

exacerbated by immunosuppressionbull The therapies available for the can-

cerbull Whether immunosuppressive medica-

tions interfere with ability to admin-ister the standard chemotherapy

202 For patients with Kaposi sarcoma we suggestusing mTORi along with a reduction in overallimmunosuppression (2C)

DOQIRationale andCommentary

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

2123 It is reasonable to manage these abnor-malities as for patients with CKD stages3-5 (Not Graded)

213 In patients with CKD stages 1ndash5T we suggest that25(OH)D (calcidiol) levels might be measuredand repeated testing determined by baseline valuesand interventions (2C)

215 In patients with an eGFR greater than approxi-mately 30 mLmin173 m2 we suggest measuringBMD in the first 3 months after kidney transplantif they receive corticosteroids or have risk factorsfor osteoporosis as in the general population (2D)

2163 There are insufficient data to guide treat-ment after the first 12 months (NotGraded)

217 In patients with CKD stages 4ndash5T we suggest thatBMD testing not be performed routinely becauseBMD does not predict fracture risk as it does in thegeneral population and BMD does not predict thetype of kidney transplant bone disease (2B)

218 In patients with CKD stages 4ndash5T with a knownlow BMD we suggest management as for patientswith CKD stages 4-5 not on dialysis (2C)

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

DIGORecommendations inChapter 22ematologic Complications

221 Perform a complete blood count at least (NotGraded)bull daily for 7 days or until hospital discharge

whichever is earlierbull two to three times per week for weeks 2-4

weekly for months 2-3bull monthly for months 4-12bull then at least annually and after any change in

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

2511 Evaluate adults for sexual dysfunction afterkidney transplantation (Not Graded)

2512 Include discussion of sexual activity and counsel-ing about contraception and safe sex practices infollow-up of adult KTRs (Not Graded)

2521 We suggest waiting for at least 1 year aftertransplantation before becoming pregnant andonly attempting pregnancy when kidney func-tion is stable with 1 gday proteinuria (2C)

2522 We recommend that MMF be discontinued orreplaced with azathioprine before pregnancyis attempted (1A)

2523 We suggest that mTORi be discontinued orreplaced before pregnancy is attempted (2D)

2524 Counsel female KTRs with child-bearing poten-tial and their partners about fertility and preg-nancy as soon as possible after transplantation(Not Graded)

2525 Counsel pregnant KTRs and their partners aboutthe risks and benefits of breastfeeding (NotGraded)

2526 Refer pregnant patients to an obstetrician withexpertise in managing high-risk pregnancies(Not Graded)

2531 We suggest that male KTRs and their partners beadvised thatbull male fertility may improve after kidney trans-

plantation (2D)bull pregnancies fathered by KTRs appear to have

no more complications than those in thegeneral population (2D)

2532 We recommend that adult male KTRs beinformed of the possible risks of infertilityfrom mTORi (1C)25321 We suggest that adult male KTRs

who wish to maintain fertility shouldconsider avoiding mTORi or bank-ing sperm prior to mTORi use (2C)

DOQIRationale andCommentary

SexualDysfunction

Sexual dysfunction is a topic often over-ooked in clinic visits but one that manyatients want addressed Sexual dysfunctionas been reported in 30-60 of KTRs8586

he use of 5-phosphodiesterase inhibitors tomprove male erectile dysfunction appears toe safe in KTRs Although KDIGO recommen-ations 2511 and 2512 are not graded ourDOQI work group concurred with these rec-

mmendations t

Pregnancyand theEffect of ImmunosuppressiveDrugsonTeratogenicity

Counseling about contraception in the first yearosttransplant a KDIGO guideline supported byASTonsensus guidelines on pregnancy87 is importantecause fertility may return to normal early post-ransplant The effect of transplant immunosuppres-ive drugs on fertility and teratogenicity must benderstood Mycophenolate compounds are rated asategory D by the US Food and DrugAdministration

FDA) and should be discontinued in women contem-lating pregnancy (Guideline 2522) Despite theame FDA rating for azathioprine there have beenears of experience with its use in pregnant KTRslthough it may be prudent to avoid sirolimus therapyuring pregnancy our work group was divided regard-ng KDIGO recommendation suggestion 2523 somef us agreed that mTOR-inhibitor therapy should betopped in pregnancy while others did not think thereas enough evidence to support this recommenda-

ion Until further data emerge regarding the safety ofTOR inhibitors in pregnancy this precaution must

e weighed against the risks and inconvenience ofhanging immunosuppression therapy All pregnantTRs are considered high-risk pregnancies and shoulde followed up by a high-risk obstetric team

Effect of SirolimusonSpermatogenesis

mTOR inhibitors can decrease testosterone levelsnd male fertility and we therefore concur that coun-eling males treated with this agent is importantKDIGO 2532) Implementation of this recommen-ation will require awareness on the part of the physi-ian when patients are switched to this drug because its used infrequently as an initial agent

DIGORecommendations inChapter 26ifestyle

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

Screening

It is recognized that KTRs have a higher inci-ence of malignancy particularly those associatedith specific viral infections Although cancer

creening may have benefits in this higher riskopulation it should be reinforced that some meth-ds of screening have significant risks which shoulde considered on an individualized basis particu-arly in patients who have projected survival lesshan 5 years

Screening forCancer inPatientsWithHepatitis

Many patients who have underlying cirrhosisn the United States will be followed up by arofessional specializing in liver disease whoay provide additional insight into this cancer

creening recommendation Based on a recentuestionnaire of US gastroenterologists only 50creen patients for hepatocellular carcinoma70

DOQIRationale andCommentary

Table 1 (Table 29 in the KDIGO report3 andxcerpted from Grulich et al71) lists cancershat are increased most in immunosuppressedTRs based on standardized incidence ratios

SIRs) which compare the incidence toatched populations Cancers with the highestIRs may be those most likely to respond to aecrease in immunosuppression Except foraposi sarcoma limited evidence is available

or a decrease in immunosuppression in theseettings A strategy to change immunosuppres-ion therapy must occur in consultation withhe transplant center Switching to sirolimusherapy and decreasing immunosuppression inatients who develop Kaposi sarcoma is basedn sound scientific rationale7273

SUMMARY OF COMMENTARY ONSECTION IV MALIGNANCY

The incidence of cancer posttransplant is 2-20times higher than that in the general population andKDIGO guidelines have been written to outline stepsfor prevention and screening With few exceptions weagree with the recommendations as outlined Skincancer is common in US transplant patients andscreening and prevention are critical However imple-mentation of guidelines for doing so including theKDIGO guidelines is a challenge because of patientpreferences against the routine use of sunscreen aswell as time constraints during office visits Althoughmany posttransplant cancers are viral mediated andrelated to immunosuppression it is less clear how toalter immunosuppression after malignancy has oc-curred We agree that although age-specific screeningfor malignancy should be incorporated into care con-sideration must be given to the risk of screening inpatients with limited life spans (5 years) because of

comorbid conditions

DIGORecommendations inChapter 21ransplant BoneDisease

211 In patients in the immediate post kidney trans-plant period we recommend measuring serumcalcium and phosphorus at least weekly untilstable (1B)

212 In patients after the immediate post kidney trans-plant period it is reasonable to base the frequencyof monitoring serum calcium phosphorus andPTH on the presence and magnitude of abnormali-ties and the rate of progression of CKD (NotGraded)2121 Reasonable monitoring intervals would

be (Not Graded)bull In CKD stages 1ndash3T for serum cal-

cium and phosphorus every 6-12months and PTH once with subse-quent intervals depending on baselinelevel and CKD progression

bull In CKD stage 4T for serum calciumand phosphorus every 3-6 monthsand for PTH every 6-12 months

bull In CKD stage 5T for serum calciumand phosphorus every 1-3 monthsand for PTH every 3-6 months

bull In CKD stages 3ndash5T measurement ofalkaline phosphatases annually ormore frequently in the presence of

2122 In CKD patients receiving treatments forCKDndashMBD or in whom biochemicalabnormalities are identified it is reason-able to increase the frequency of measure-ments to monitor for efficacy and sideeffects (Not Graded)

2123 It is reasonable to manage these abnor-malities as for patients with CKD stages3-5 (Not Graded)

213 In patients with CKD stages 1ndash5T we suggest that25(OH)D (calcidiol) levels might be measuredand repeated testing determined by baseline valuesand interventions (2C)

214 In patients with CKD stages 1ndash5T we suggest thatvitamin D deficiency and insufficiency be cor-rected using treatment strategies recommended forthe general population (2C)

215 In patients with an eGFR greater than approxi-mately 30 mLmin173 m2 we suggest measuringBMD in the first 3 months after kidney transplantif they receive corticosteroids or have risk factorsfor osteoporosis as in the general population (2D)

216 In patients in the first 12 months after kidneytransplant with eGFR greater than approximately30mLmin173 m2 and low BMD we suggest thattreatment with vitamin D calcitriolalfacalcidiolor bisphosphonates be considered (2D)2161 We suggest that treatment choices be

influenced by the presence of CKDndashMBD as indicated by abnormal levels ofcalcium phosphorus PTH alkaline phos-phatases and 25(OH)D (2C)

217 In patients with CKD stages 4ndash5T we suggest thatBMD testing not be performed routinely becauseBMD does not predict fracture risk as it does in thegeneral population and BMD does not predict thetype of kidney transplant bone disease (2B)

218 In patients with CKD stages 4ndash5T with a knownlow BMD we suggest management as for patientswith CKD stages 4-5 not on dialysis (2C)

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

COMPLICATIONS

DIGORecommendations inChapter 21ransplant BoneDisease

211 In patients in the immediate post kidney trans-plant period we recommend measuring serumcalcium and phosphorus at least weekly untilstable (1B)

212 In patients after the immediate post kidney trans-plant period it is reasonable to base the frequencyof monitoring serum calcium phosphorus andPTH on the presence and magnitude of abnormali-ties and the rate of progression of CKD (NotGraded)2121 Reasonable monitoring intervals would

be (Not Graded)bull In CKD stages 1ndash3T for serum cal-

cium and phosphorus every 6-12months and PTH once with subse-quent intervals depending on baselinelevel and CKD progression

bull In CKD stage 4T for serum calciumand phosphorus every 3-6 monthsand for PTH every 6-12 months

bull In CKD stage 5T for serum calciumand phosphorus every 1-3 monthsand for PTH every 3-6 months

bull In CKD stages 3ndash5T measurement ofalkaline phosphatases annually ormore frequently in the presence of

2122 In CKD patients receiving treatments forCKDndashMBD or in whom biochemicalabnormalities are identified it is reason-able to increase the frequency of measure-ments to monitor for efficacy and sideeffects (Not Graded)

2123 It is reasonable to manage these abnor-malities as for patients with CKD stages3-5 (Not Graded)

213 In patients with CKD stages 1ndash5T we suggest that25(OH)D (calcidiol) levels might be measuredand repeated testing determined by baseline valuesand interventions (2C)

214 In patients with CKD stages 1ndash5T we suggest thatvitamin D deficiency and insufficiency be cor-rected using treatment strategies recommended forthe general population (2C)

215 In patients with an eGFR greater than approxi-mately 30 mLmin173 m2 we suggest measuringBMD in the first 3 months after kidney transplantif they receive corticosteroids or have risk factorsfor osteoporosis as in the general population (2D)

216 In patients in the first 12 months after kidneytransplant with eGFR greater than approximately30mLmin173 m2 and low BMD we suggest thattreatment with vitamin D calcitriolalfacalcidiolor bisphosphonates be considered (2D)2161 We suggest that treatment choices be

influenced by the presence of CKDndashMBD as indicated by abnormal levels ofcalcium phosphorus PTH alkaline phos-phatases and 25(OH)D (2C)

2163 There are insufficient data to guide treat-ment after the first 12 months (NotGraded)

217 In patients with CKD stages 4ndash5T we suggest thatBMD testing not be performed routinely becauseBMD does not predict fracture risk as it does in thegeneral population and BMD does not predict thetype of kidney transplant bone disease (2B)

218 In patients with CKD stages 4ndash5T with a knownlow BMD we suggest management as for patientswith CKD stages 4-5 not on dialysis (2C)

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

hough bisphosphonate use may result in less

one density loss in the early posttransplanteriod no study has been sufficiently powered tohow fracture prevention using these therapies76

urthermore bisphosphonate use in patients withFR 30 mLmin or those with low bone turn-ver may cause adynamic bone disease77 Allhese limitations have made bisphosphonate useess common in US transplant patients in recentearsSteroid therapy contributes significantly to

ractures and loss of bone mass in the first 6-12onths after transplant a phenomenon ob-

erved less commonly with steroid-avoidancerotocols or after steroid therapy is with-rawn627879 Thus advocating for a steroid-voidance protocol now used in up to 30 ofS transplant centers may be a reasonablelan for patients at high risk of fractures (olderhite diabetic patients and those with previ-us fractures) to prevent further bone lossost-transplantThe KDIGO recommendations in this sec-

ion focus on the bone disease and biochemicalbnormalities that contribute to fractures inTRs similar to KDOQI recommendations

or CKD-MBD However the preponderancef fractures in the feet and in patients withiabetes suggest that other factors such aseuropathy balance and level of activity alsoay be important factors contributing to the

igh risk of fractures in KTRs8081

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

use of bisphosphonates due to the highincidence of adynamic bone disease (NotGraded)

2163 There are insufficient data to guide treat-ment after the first 12 months (NotGraded)

217 In patients with CKD stages 4ndash5T we suggest thatBMD testing not be performed routinely becauseBMD does not predict fracture risk as it does in thegeneral population and BMD does not predict thetype of kidney transplant bone disease (2B)

218 In patients with CKD stages 4ndash5T with a knownlow BMD we suggest management as for patientswith CKD stages 4-5 not on dialysis (2C)

DOQIRationale andCommentary

MeasuringCalciumandPhosphorus

Recommendations for the diagnosis and treat-ent of posttransplant bone disease were derived

rom those created by the CKD-MBD KDIGOork group5 Our KDOQI work group concurredith the high-level recommendation to measure

alcium and phosphorus weekly after transplantecause dramatic changes can occur in these ele-ents with restoration of kidney function Sugges-

ions for intervals of follow-up after the early trans-lant period are reasonable and based on therequency of CKD posttransplant Although theres consensus that parathyroid hormone (PTH) lev-ls should be monitored it is not clear at what levelTH should be maintained in KTRs There also areata to suggest that higher than normal PTH levelsay be required to preserve bone formation inTRs on steroid therapy74

MeasuringandTreatingVitaminDDeficiency

Vitamin D deficiency is extremely common inTRs75 and low vitamin D levels should be

epleted to control secondary hyperparathyroid-sm Although vitamin D repletion can lead to aecrease in PTH levels there are no data formprovement in bone disease with repletion

BoneMineralDensityandPreventionofBoneLossWithVitaminDAnaloguesorBisphosphonates

Although the current KDIGO suggestion rec-mmendation (215) supports previous ASTuidelines to obtain an early bone mineral den-ity (BMD) study in KTRs with GFR 30 mLin there are no data correlating results of BMDeasurements with fracture risk in KTRs Al-

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

KDOQI Commentary 25

ARTICLE IN PRESS

DOQIRationale andCommentary

Anemia

Anemia is a common problem posttransplantnd often occurs at higher levels of GFR inTRs than in other patients with CKD82 The

uthors base their recommendations for evalua-ion and treatment on KDOQI guidelines fornemia in CKD which are reasonable andtraightforward83 Financial coverage must bexplored when discharging a new KTR on eryth-opoietin replacement therapy because reimburse-ent may be different from when the patient was

n dialysis therapy

Neutropenia

KDIGO suggestion 223 is reasonable Now thatMV prophylaxis with valgancyclovir is routine inS transplant centers and induction with lympho-

yte-depleting agents frequently is used significanteutropenia is observed more frequently in thearly posttransplant months especially in patientssing mycophenolate compounds Rejection riskould be increased if MPA dose is decreased how-ver CMV disease could occur if valgancyclovirherapy is discontinued Some centers use granulo-yte colony-stimulating factor to treat neutropenian the early posttransplant period to avoid discon-inuing valgancyclovir therapy or decreasing MPAose These decisions should always be made byhe transplant center

Erythrocytosis

This phenomenon usually occurs only in pa-ients with good kidney function and is importanto recognize and treat appropriately AST guide-ines for treatment (hemoglobin 17-19 gdLematocrit 51 to 52) should be followedCE inhibitors are the treatment of choice

KDIGO recommendation 224) and low dosesf these agents often are effective

DIGORecommendations inChapter 23yperuricemia andGout

231 We suggest treating hyperuricemia in KTRs whenthere are complications such as gout tophi or uricacid stones (2D)2311 We suggest colchicine for treating acute

gout with appropriate dose reduction forreduced kidney function and concomitantCNI use (2D)

2312 We recommend avoiding allopurinol in

patients receiving azathioprine (1B) a

2313 We suggest avoiding NSAIDs and COX-2inhibitors whenever possible (2D)

DOQIRationale andCommentary

Colchicine can be very effective in treatingout however higher doses than those describedy the authors in the KDIGO guideline often areeeded The occurrence of diarrhea causing pre-enal azotemia and deterioration in kidney func-ion limits the use of colchicine in KTRs to anven greater extent than the occurrence of myop-thy which usually occurs only in patients withery poor kidney function It is critical to avoidhe use of allopurinol in patients on azathioprineherapy (KDIGO guideline 2312) because ofnhibition of azathioprine metabolism by thisrug If long-term suppression of uric acid syn-hesis is needed in a patient on azathioprineherapy one can switch to a mycophenolateompound because these do not depend on xan-hine oxidase for metabolism

DIGORecommendations inChapter 24 GrowthndDevelopment

241 We recommend measuring growth and develop-ment in children (1C)bull at least every 3 months if 3 years old (includ-

ing head circumference) (Not Graded)bull every 6 months in children 3 years until final

adult height (Not Graded)

242 We recommend using rhGH [recombinant humangrowth hormone] 28 IUm2week (or 005 mgkgday) in children with persistent growth failure afterkidney transplantation (1B)

243 We suggest minimizing or avoiding corticosteroiduse in children who still have growth potential (2C)

DOQIRationale andCommentary

Improving growth in children remains one of therimary goals for pediatric KTRs There now haveeen years of experience with the use of recombi-ant human growth hormone and the risks seem toe minimal compared with the benefits84 Thus weoncur with KDIGO recommendations 241 and42 Although it generally is thought to be prefer-ble to avoid steroid therapy in growing childrenvidence in support of this approach is limitedurthermore the risk of rejection in children hasade some US centers reluctant to use steroid-

voidance protocols

DIGORecommendations inChapter 25 Sexualunction andFertility

2511 Evaluate adults for sexual dysfunction afterkidney transplantation (Not Graded)

2512 Include discussion of sexual activity and counsel-ing about contraception and safe sex practices infollow-up of adult KTRs (Not Graded)

2521 We suggest waiting for at least 1 year aftertransplantation before becoming pregnant andonly attempting pregnancy when kidney func-tion is stable with 1 gday proteinuria (2C)

2522 We recommend that MMF be discontinued orreplaced with azathioprine before pregnancyis attempted (1A)

2523 We suggest that mTORi be discontinued orreplaced before pregnancy is attempted (2D)

2524 Counsel female KTRs with child-bearing poten-tial and their partners about fertility and preg-nancy as soon as possible after transplantation(Not Graded)

2525 Counsel pregnant KTRs and their partners aboutthe risks and benefits of breastfeeding (NotGraded)

2526 Refer pregnant patients to an obstetrician withexpertise in managing high-risk pregnancies(Not Graded)

2531 We suggest that male KTRs and their partners beadvised thatbull male fertility may improve after kidney trans-

SexualDysfunction

Sexual dysfunction is a topic often over-ooked in clinic visits but one that manyatients want addressed Sexual dysfunctionas been reported in 30-60 of KTRs8586

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

DIGORecommendations inChapter 25 Sexualunction andFertility

2511 Evaluate adults for sexual dysfunction afterkidney transplantation (Not Graded)

2512 Include discussion of sexual activity and counsel-ing about contraception and safe sex practices infollow-up of adult KTRs (Not Graded)

2521 We suggest waiting for at least 1 year aftertransplantation before becoming pregnant andonly attempting pregnancy when kidney func-tion is stable with 1 gday proteinuria (2C)

2522 We recommend that MMF be discontinued orreplaced with azathioprine before pregnancyis attempted (1A)

2523 We suggest that mTORi be discontinued orreplaced before pregnancy is attempted (2D)

2524 Counsel female KTRs with child-bearing poten-tial and their partners about fertility and preg-nancy as soon as possible after transplantation(Not Graded)

2525 Counsel pregnant KTRs and their partners aboutthe risks and benefits of breastfeeding (NotGraded)

2526 Refer pregnant patients to an obstetrician withexpertise in managing high-risk pregnancies(Not Graded)

2531 We suggest that male KTRs and their partners beadvised thatbull male fertility may improve after kidney trans-

plantation (2D)bull pregnancies fathered by KTRs appear to have

no more complications than those in thegeneral population (2D)

2532 We recommend that adult male KTRs beinformed of the possible risks of infertilityfrom mTORi (1C)25321 We suggest that adult male KTRs

who wish to maintain fertility shouldconsider avoiding mTORi or bank-ing sperm prior to mTORi use (2C)

KDOQI Commentary 27

ARTICLE IN PRESS

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients

KDOQI Commentary 27

ARTICLE IN PRESS

DIGORecommendations inChapter 27Mentalealth

27 Include direct questioning about depression andanxiety as part of routine follow-up care after kidneytransplantation (Not graded)

DOQIRationale andCommentary

Depression and anxiety in the transplant popu-ation conditions that may affect adherence of-en are overlooked because patients are expectedo be content with their ldquogift of liferdquo Attention tohis area in the short time allotted for patientisits often requires the help of a multidisci-linary team especially social workers to sur-ey patients for signs of these disorders and gethe help they need

SUMMARY OF COMMENTARY ON SECTION VOTHER COMPLICATIONS

RESEARCH

At the end of each section members of the KDIGOork group made several suggestions for areas of

uture research Our KDOQI work group agreed withhe critical importance of research in these areas toreate evidence upon which future recommendationsnd guidelines can be based

CONCLUSION

The new KDIGO guideline for the care ofidney transplant patients are broad in scope and

Metabolic complications are common posttransplantand attention to the prevention and treatment of theseissues many resulting from side effects of immunosup-pressive drugs constitute a large part of posttransplantcare For the most part our KDOQI work group agreedwith KDIGO recommendations for the prevention andtreatment of bone disease except for having less enthusi-asm for the use of bisphosphonates which now are useduncommonly in KTRs in the United States We agreedwith recommendations for managing hematologic prob-lems gout and growth in children We also concur withrecommendations for management of immunosuppres-sive drugs in pregnancy although our group was dividedabout whether mTOR-inhibitor therapy must be discontin-ued in pregnancy We applaud the KDIGO group forincluding sections on mental health and lifestyle becausethese are important areas that require more attention inthe medical care of KTRs

hould serve as guide for all clinicians caring for A

TRs including transplant clinicians nephrolo-ists nurses and fellows in training Our KDOQIork group concurred with many of the KDIGO

ecommendations except in some important ar-as related to immunosuppression Decisionsbout immunosuppression in the United Statesre largely made by transplant centers and areependent in part on the specific patient popula-ion served Emphasis in the KDIGO guideline isade for the need for continued monitoring ofTRs with the use of kidney biopsy to determine

auses of graft dysfunction even after the earlyosttransplant period Because of increasing rec-gnition of entities such as BK nephropathy andntibody-mediated rejection as important causesor graft dysfunction it is important to haveccess to proper processing and interpretation ofhe transplant biopsy specimen by pathologistsith expertise in this area Most but not allDIGO recommendations are relevant to USatients However implementation of many mayemain a major challenge because of issues ofrug cost and limitation in resources needed tossist in the tasks of educating counseling andmplementing and maintaining lifestyle changesowever these KDIGO recommendations offer

n excellent road map to navigate the complexare of kidney transplant patients
