Interpretation of Results of Tests for Hepatitis C Virus (HCV) Infection and Further Actions

Test Outcome Interpretation Further Actions

HCV antibody

nonreactive

No HCV antibody

detected

Sample can be reported as nonreactive for HCV antibody.

No further action required.

If recent exposure in person tested is suspected, test for HCV RNA.*

HCV antibody reactive Presumptive HCV

infection

A repeatedly reactive result is consistent with current HCV infection, or past

HCV infection that has resolved, or biologic false positivity for HCV

antibody.

Test for HCV RNA to identify current infection.

HCV antibody reactive,

HCV RNA detected Current HCV infection

Provide person tested with appropriate counseling and link person tested to

care and treatment.†

HCV antibody reactive,

HCV RNA not detected No current HCV infection

No further action required in most cases.

If distinction between true positivity and biologic false positivity for HCV

antibody is desired, and if sample is repeatedly reactive in the initial test,

test with another HCV antibody assay.

In certain situations, ξfollow up with HCV RNA testing and

appropriate counseling.

*If HCV RNA testing is not feasible and person tested is not immunocompromised, do follow-up testing for HCV antibody to demonstrate seroconversion. If the person tested is immunocompromised, consider testing for HCV RNA. †It is recommended before initiating antiviral therapy to retest for HCV RNA in a subsequent blood sample to confirm HCV RNA positivity. ξIf the person tested is suspected of having HCV exposure within the past 6 months, or has clinical evidence of HCV disease, or if there is concern regarding the handling or storage of the test specimen.

• HCV+ patients of three community health centers in Washington DC

were identified and distributed in a non-randomized manner to

receive treatment from either

– Nurse practitioner (NP)

– Primary care physician (PCP)

– Specialist (BC/BE Infectious Disease or Hepatology)

• Providers underwent uniform 3-hour training on IDSA-AASLD

therapeutic guidelines

• Patients were treated with ledipasvir and sofosbuvir (LDV/SOF)

as per FDA label

• The primary outcome: SVR12

• Adherence to visits at 4, 8, and 12 weeks (all -7 to +14 days),

were categorized by a composite score of attendance

HIV/HCV Co-Infection: Considerations

Sulkowski MS. Liver Int. 2016 Jan;36 Suppl 1:43-6.

• High prevalence of HCV co-infection

• Rapid progression of HCV-related liver disease

• Poor response to interferon-alfa based

treatment regimens

• Drug interactions ARVs and DAAs

• Estimated 4-5 million co-infected patients worldwide

• Prevalence 10-15%, upto 50% in HIV patients who inject

or have injected in the past

• Increased sexual transmission in MSM

(increase possibility of reinfection)

HIV/HCV Co-Infection

• Successful HCV treatment must be

combined with:

– Strategies to reduce the risk of re-infection

following SVR

– Education on risk

– Access to programs to promote needle-exchange

– Opioid substitution therapy

– Healthy sexual behavior and the use of protective

barrier methods.

Decompensated Cirrhosis: Child’s B/C

Soriano V. Expert Opin Pharmacother. 2016;17(2):217-29.

• Liver dysfunction with reduced elimination of drug

may cause toxicity and further decompensation

(Simeprevir, Sofosbuvir)

• ?Reduced exposure/efficacy due to hypoalbuminemia

but free drug concentration does not change (no dose

adjustment requirement)

• Protease Inhibitors are not used

• Overall SVR rates are lower with advanced cirrhosis compared to

those with less fibrosis or portal hypertension

• Consideration for Liver transplantation and timing of HCV treatment

• MELD Purgatory

HCV After Liver Transplantation

• Increased risk for developing ESLD, 25% in 5 years

• Major consideration is DAA interaction with either

tacrolimus or cyclosporine

• Simeprevir and daclatasvir only slightly increase

cyclosporine or tacrolimus exposure

• Sofosbuvir does not have any clinically significant DD

interactions with tacrolimus/cyclosporine

• 3D regimen can be used as long as drug monitoring

of calcineurin inhibitors is performed (risk of

calcineurin toxicity)

Renal Insufficiency and Hemodialysis

Challenging comorbidity HCV and CKD are associated with

higher mortality rates

• Certain DAA treatment regimens achieve high SVR rates

in patients with decompensated cirrhosis or severe renal

impairment but not both

• Elbasvir/grazoprevir and

ombitasvir/paritaprevir/ritonavir/dasabuvir have favorable

pharmacokinetic profiles for patients with severe renal

impairment, but only available for GT 1 and 4

• Contraindicated in decompensated cirrhosis.

An excellent strategy of early

post-transplant HCV

eradication to facilitate use

of HCV+ organs

Transplantation. 2016 Aug 4.

Title: Use of HCV+ donors does not affect HCV clearance with directly

acting antiviral therapy but shortens the wait time to kidney transplantation

• 43 renal transplant recipients with 4 different DAA regimens

• 100% achieved a sustained viral response by 12 weeks after therapy

• DAA regimens were well tolerated

• Recipients of HCV+ organs experienced significantly shorter

wait-times to transplantation, 485 days (IQR 228-783) versus

969 days (IQR 452-2008) p=0.02.

DAA Failures

• DAA failures occurs in roughly 10% of chronic hepatitis C patients

treated outside clinical trials.

• Most cases are relapses instead of viral breakthroughs on therapy.

• Occur more frequently in treatment-experienced patients,

those with advanced cirrhosis and HCV genotypes 3 or 1a

• DAA failure is rare in non-cirrhotics patients (seen only

when therapy is given for < 12 wks)

• Virologic breakthrough during DAA therapy = poor drug adherence.

• DAA failure is frequently associated with emergence of RAVs

• HCV drug resistance testing will help choosing the most

convenient salvage DAA regimen as re-treatment of prior

DAA failures.

Benítez-Gutiérrez. Expert Opin Pharmacother. 2016 Jun;17(9):1215-23.

• Virologic challenges

– Presence of RAVs (prior DAA failure)

– Exclude HCV genotype shift (misinterpretation)

– Exclude HCV reinfection (risk behaviors)

• Strategic management

– Adding ribavirin

– Extent the length of therapy

• Maximize drug benefit

– Avoid drug interactions (comorbidities)

– Prevent and manage side effects

– Ensure drug adherence

HCV in People Who Inject Drugs: PWID

• Main risk group for transmission

• HCV prevalence range <20%->80%, ~ 50%

• Younger patients with less advanced liver disease and therefore strategies which

target more severe liver disease may have little to no impact on the epidemic

• Provider concerns surrounding potential poor treatment outcomes among

PWID persist

• Established programs are built on existing infrastructure for drug user: addiction

clinics, community health centers and prisons

• HCV treatment needs to be combined with prevention strategies to reduce

reinfection, and ensure stable reductions in transmission occur

• Opiate substitution therapy and needle and syringe programs are effective at

reducing an individuals’ risk of HCV acquisition

• Combination HCV treatment and harm reduction strategies: reduce HCV

incidence, and prevent reinfection post treatment.

HCV in People Who Inject Drugs: PWID

• PWID should be counselled on the importance of adherence in

attaining an SVR

• A history or recent IDU are not associated with reduced SVR and

decisions to treat should be made on a case-by-case basis

• PWID with ongoing social issues, history of psychiatric disease and

those with more frequent drug use during therapy are at risk of lower

adherence and SVR and need to be monitored closely

during therapy

• HCV treatment for PWID should be considered on an individualized

basis and delivered within a multidisciplinary team setting

• Access to harm reduction programs, social work and social support

services should be a component of HCV clinical management

• Universal access to therapy is required

Summary

• Chronic HCV is an under diagnosed disease

• Efforts should continued to be made to screen and link

affected patients to care

• Treatment of HCV is short course, less toxic and

highly efficacious

• Efforts are ongoing to increase HCV providers

• Some PCP are treating HCV with DAA and this

is encouraging

• Complex, difficult to treat patient populations should be

treated by a specialist
