PREFACE
Pharmacy Practice, which was traditionally product-centered, has now shifted towards patient care. Pharmaceutical care, which
is comprehensive and patient focused, is vital in ensuring that patient receive rational, safe and effective treatment. By adopting pharmaceutical care to Human Immunodeficiency Virus (HIV) patients, a pharmacist needs to cooperate with the patient and other health
professionals (e.g. infectious disease consultants, physicians, medical officers, nurses and social workers) in the management of patients, focusing on the medication therapy.
Due to the vast development in the field of HIV medicines over the last few years, the first edition of the Retroviral Disease (RVD) Protocol that was published in 2010 has been revised. This second edition protocol combines the management of the adult & paediatric HIV patients. This protocol is meant for pharmacists in Ministry of Health (MOH) in providing their expertise in Retroviral or Pediatric Retroviral Medication Therapy Adherence Clinic (RVD or PRVD MTAC). This protocol will ensure the standardisation of practice and also enable the pharmacists to fully contribute as part of the healthcare team throughout Minsitry Of Health’s facilities.
I would like to thank the Clinical Pharmacy Working Committee (Retroviral Disease-RVD Subspecialty) Pharmaceutical Services Division, MOH for their contribution and commitment to the publication of this protocol.

1 INtRoDuCtIoN
Infection of HIV leads to progressive immune destruction as a result of persistent viral replication. Therefore, antiretroviral treatment has been shown to improve CD4 cell count, reduce viral replication, reduce the frequency of opportunistic infection, improve quality of life and hence, prolong life expectancy of HIV infected patients. Through collaboration with other healthcare providers, pharmacists could play an important role in providing pharmaceutical care to HIV patients in order to achieve a better therapeutic outcome. By adopting pharmaceutical care, a pharmacist needs to cooperate with the patient and other health professionals in planning specific therapeutic outcomes for the patient.
� Acquisition of infection through perinatal exposure for many infected children.
� In utero, intrapartum and/or postpartum neonatal exposure to zidovudine and other antiretroviral medications in most perinatally infected children.
� Requirement for the use of HIV virologic tests to diagnose perinatal HIV infection in infants under the age of 18 months.
� Age-specific differences in CD4 cell counts.
� Changes in pharmacokinetic parameters with age caused by the continuing development and maturation of the organ systems involved in drug metabolism and clearance.
1.1 HIV Infection in Paediatric
The pathogenesis of HIV infection and the general virologic and immunologic principles underlying the use of antiretroviral therapy in paediatrics are similar to adults. However, there are some unique considerations for HIV-infected infants, children and adolescents as stipulated below:
3Protocol Medication Therapy Adherence Clinic: Retroviral Disease (Adult & Paediatric) 2nd Edition 2014
Different from adult HIV patients, children living with HIV infections are, as a group, growing older, bringing new challenges in medication adherence, drug resistance, and management of multiple drugs.
� Differences in the clinical and virologic manifestations of perinatal HIV infection secondary to the occurrence of primary infection in growing, immunologically immature persons.
� Special considerations associated with adherence to antiretroviral treatment for infants, children and adolescents.
1.1.1 Disease Disclosure Status
Disease disclosure status in children living with HIV is one of the crucial factors that affect medication adherence in paediatric patients. Thus, the pharmacist should be aware of the importance of maintaining patient confidentiality throughout the counselling session. At the clinic, PRVD MTAC pharmacist should assess not only the patient readiness (in older children) to adhere to medication therapy, but also the willingness of the caregiver to make sure medications are served correctly and discuss other medication related factors.
Disclosure of HIV infection status to children and adolescents should take into consideration of their age, psychosocial maturity, the complexity of the family dynamics and the clinical context. The paediatrician will discuss and plan the process for disclosure with the parents/family members and access the child’s knowledge and coping capacity. The process of disclosure will be individualised to include child’s cognitive ability, developmental stage, clinical status and social circumstances.
Disclosure of the disease status may lead to stigmatisation, discrimination or ostracism toward the child and other family members. Hence, pharmacists should be aware of the child’s disease disclosure status while conducting counselling sessions and concern about the impact of the disclosure on the child’s emotional health.

� Assess patient’s readiness to adhere to medication therapy.
� Provide ongoing monitoring of drug adherence and evaluate the presence of social stressors that may impair adherence.
� Patient assessment for medication-related factors.
� Interpret laboratory results to monitor outcomes of medication therapy and identify potential drug toxicities.
1.1.2 Partial Disclosure and Full Disclosure of RVD Status
Partial Disclosure Full Disclosure
Age � ≥ 7 years old. � Depends on the child’s
psychosocial maturity.
� ≥ 12 years old. � Depends on the child’s
cognitive and emotional understanding of illness and dying.
� Also depends on parent’s/caregiver’s readiness.

48 Protocol Medication Therapy Adherence Clinic:
Retroviral Disease (Adult & Paediatric) 2nd Edition 2014
Table 1: Known and expected Adverse Drug events associated with NRTIs
Drug Adverse Events
Abacavir (ABC) � Hypersensivitiy syndrome (usually occurs in first 6 weeks of therapy) which can be characterized by fever, rash, progressive nausea, malaise, diarrhea, respiratory symptoms such as sore throat, cough and shortness of breath.
� Nausea, headache � Rare lactic acidosis and hepatitic steatosis
Didanosine (ddI) � Pancreatitis � Peripheral neuropathy � Nausea, diarrhea � Lactic acidosis with hepatic steatosis is a rare but potentially life-
threatening toxicity associated with use of NRTIs, particularly stavudine
Emtricitabine (FTC) � Minimal toxicity � Diarrhea, nausea, headache � Hyperpigmentation/skin discoloration of palms and soles
Lamivudine (3TC) � Minimal toxicity � Headache, dry mouth
Stavudine (d4T) � Peripheral neuropathy � Lactic acidosis � Pancreatitis � Lipodystrophy � Dyslipidaemia
Warning: Concomitant use with ddI appears to have increased risk of fat distribution, peripheral neuropathy, pancreatitis and lactic acidosis.
Tenofovir (TDF) � Flatulence, abdominal discomfort, headache, nausea, diarrhea, vomiting � Asthenia � Acute renal insufficiency, Fanconi syndrome � Decrease bone mineral density (BMD) particularly of the lumbar spine
Zidovudine (AZT) � Bone marrow suppression: � Macrocytic anemia (may be seen as early as 2 to 6 weeks after initiation
of therapy; avoid initiating AZT in those with Hgb<9) � Neutropenia (Usually occurs after 12-24 weeks) � Gastrointestinal intolerance, headache, nausea, � Asthenia � Hyperpigmentation of skin and nails
HAARt ADVERSE EFFECtS CHARtA. Nucleoside Reverse trascriptase Inhibitors (NRtI)
NRTI damages the cellular mitochondria function, which is believed to cause many, if not all, side effects associated. Clinical manifestations of mitochondrial toxicity are lactic acidosis, hepatitic steatosis, pancreatitis, peripheral neuropathy, lipoatrophy (fat loss), skeletal myopathy/cardiomyopathy, and HIV associated neuromuscular weakness.
APPENDIX C3
49Protocol Medication Therapy Adherence Clinic: Retroviral Disease (Adult & Paediatric) 2nd Edition 2014
B. Non-Nucleoside Reverse trascriptase Inhibitors (NNRtI)
NNRTIs are associated with hypersensitivity reactions, commonly characterized by skin rash, usually begins within 1 – 3 weeks of therapy. Rare cases of Stevens - Johnson Syndrome (SJS) have been reported with the use of all four NNRTIs, the highest incidence seen associated with nevirapine use.

abnormal thinking, impaired concentration, amnesia, agitation, hallucinations, and euphoria
� Severity usually decreases within 2 – 4 weeks after initiation of efavirenz � Elevated liver transaminase levels, hepatoxicity (rare) � Dyslipidemia
Etravirne (ETV) � Elevated liver transaminase levels � Rash � Nausea
Nevirapine (NVP) � 33% incidence of rash, 5% of persons with rash will develop SJS. Usually develops within first 6 weeks of therapy
� Hepatitis f Women who start NVP therapy with CD4 cell counts greater than
250 (and men with CD4 counts>400) have a 12 times greater risk of hepatitis.
� Elevated liver transaminase levels. Hepatotoxicity is more common at higher CD4 cell counts, in women and in patients with hepatitis B or C.
� Dyslipidemia
