FOREWORD
This publication of the National Guidelines for Management of HIV/AIDS marks another milestone in
3rd
the nation’s response to HIV/AIDS. With the implementation of these guidelines, Bhutan will be
increasing the baseline CD4+T lymphocyte count for initiation of Antiretroviral therapy (ART) from 350
cells/mm3 or below to 500 cells/mm3 to reap the benefits of early treatment initiations. Earlier treatment
brings the dual advantage of keeping people healthier longer and reducing the risk of virus transmission
to others. This guideline now recommends that pregnant women and children under the age of five
years start treatment immediately after diagnosis. Treatment will also be offered to HIV positive person,
in a sero-discordant relationship irrespective of the CD4 count to reduce the risk of transmission. With
the right therapy, started at the right time, people with HIV can now expect to live long and healthy lives.
They are also able to protect their sexual partners and infants as the risk of transmitting the virus is
greatly reduced.
The guidelines were prepared keeping in view our country’s context. The content of this document are a
synthesis of the WHO recommendations and is formulated to suit the needs of our country. With the
increase in the CD4 threshold for treatment initiation, more people with HIV will be put on treatment and
will require appropriate management. This document provides health care professionals with the
knowledge base that will assist in providing the appropriate treatment and management of HIV/AIDS.

Introduction
People access HIV treatment, care and prevention through the gateway of HIV testing and
counseling. It is estimated that globally about half of the people living with HIV do not know
their HIV status. The people who do know their status often test late, this could mean that
many people start treatment when they are already significantly immune compromised,
resulting in poor health outcomes and ongoing HIV transmission. The overall HIV testing
and counseling goal for the National HIV/AIDS Control Programme is to intensify the HIV
diagnostic facilities to detect as many people as possible at the earlier stage of the infection
and subsequently make linkage to the continuum of care.
Rapid HIV antibody testing facilities are available in all the district hospitals including some
BHUs and the free standing Health Information and Service Centers (HISCs) in four major
towns. ELISA testing facilities are currently available only in the national and regional
referral hospitals including some district hospitals in strategic locations.
All forms of HIV testing and counseling will be voluntary. However, the provider initiated
testing and counseling (PITC) are provided to the individual clients based on their existing
health conditions such as for patients with tuberculosis (TB), sexually transmitted infections
(STI) and ante-natal clinic (ANC) attendees. Similarly for the general population the HIV
testing is offered adhering to the five C’s as follows:
• Consent - HIV testing is initiated only after obtaining an informed consent.
• Confidentiality- HIV counseling and testing services are kept confidential
• Counseling- HIV counseling and testing services must be accompanied by pre-test
information and post-test counseling.
• Correct test- HIV counseling and testing providers should strive to provide high-
quality and quality assured testing services
• Connection to care & treatment- Connections to prevention, care and treatment
services include the provision of referral system for appropriate follow-up, including
treatment, care and support services.
Pre-Test Counselling:
• Make an appointment for the test result
• Basic information about the potential benefits of testing
• Pre-test counseling performed after obtaining informed consent
• Basic information about HIV and its transmission
• Risk assessment and risk reduction plan
• Basic information about the test result
• Condom use including demonstration
7
• Referral if required
Trained counselors are available in all hospitals including the Health Information Service
Centers (HISC) to provide voluntary counseling and testing services. They also carry out
patient monitoring and follow-up for continuum of care as well as recording and reporting of
the HIV data including quarterly VCT reporting.
HIV testing facilities are available in all the health facilities including HISCs in four major
towns of Thimphu, Phuentsholing, Gelephu and SamdrupJongkhar. The different level of
HIV testing facilities are as follows:

HIV testing and confirmation procedures will be as per the national protocol. All testing centers will use
the standard operating procedures (SOP) for initial screening (A1) at their facilities using the rapid test
kits or ELISA wherever feasible. The test will be repeated for all the initial reactive (IR) tests. If the
repeat test is reactive, the samples will be sent to the Public Health Laboratory for a confirmatory test.
Tests A2 and A3 are carried out at the PHL.

Summary of testing approaches for infants
Any infant born to infected mothers should be tested for HIV as in the following table:
Table 2
Healthy, HIV Serological test 12 months All health facilities Repeat at 18 months if
exposed infant (Rapid/ELISA) and above positive
Healthy, HIV Serological test 18 months All health facilities For confirmation of HIV
exposed baby (Rapid/ELISA) status
To reduce the cost of virological testing, a serological test should be done for HIV-exposed infants and
children age 9 to 18 months. Only those with reactive serological assays should have a virological test
to confirm HIV infection and determine who needs ART.

Introduction
The primary aim of ART is the prevention of mortality and morbidity associated with chronic HIV
infection. This goal is best accomplished by using effective ART to maximally inhibit HIV replication so
that plasma HIV RNA levels (viral load) remain below that detectable by commercially available assays.
Durable viral suppression improves immune function and quality of life, lowers the risk of both AIDS-
defining and non-AIDS-defining complications, and prolongs life. The effectiveness and tolerability of
ART has improved significantly over the last 15 years. A further aim of treatment is the reduction in
sexual transmission of HIV and for some patients may be the primary aim. The use of ART to prevent
mother-to-child transmission is universally accepted and is addressed in this guideline under the
PMTCT.
Goals of Therapy
b Virological Goals Reduction of plasma viral RNA to undetectable levels (<50 copies per mL)
especially in the first few months of therapy to limit the risk of treatment failure.
c Immunological Goals Restore and preserve immunologic function which is assessed by CD4 T cell
count. The ‘normal value is 800-1050 cells/mm3
d Therapeutic Goals Rationalize the sequencing of drugs to achieve clinical, virological and
immunological goals while maintaining treatment options, limiting drug toxicity
and facilitating adherence.
The ultimate aim of ART is to achieve and maintain undetectable levels of plasma HIV RNA and CD4
counts in the normal range.
Definition of ART
It is a combination treatment with three or more anti-retroviral agents to suppress viral replication in
order to prolong and improve the quality of life.
a. Access to HIV voluntary counselling and testing and follow up counselling services. This also
includes psychological support and adherence to treatment.
b. A well-equipped medical centre for diagnosis and management of opportunistic infections.
c. Reliable laboratory services capable of carrying out investigations such as CBC,
biochemistries, CD4 counts, culture facilities and viral load estimations.
d. Drugs: reliable, affordable and sustained supply of anti-retrovirals and drugs for prophylaxis
and treatment of opportunistic infections (OIs).

When to start ART?
Early treatment initiation is associated with clinical and HIV prevention benefits, improving survival and
reducing the incidence of HIV infection at the community level.
Tenofovir is well tolerated, it has no interaction with Zidovudine or Stavudien and its use harmonizes the
regimen with HIV and HBV co-infection. It also has advantage of once a day dosing.
Table 3:This guideline recommends the use of the following combination of drugs as the first line
regimen:
What ART/ARV regimens to start with
Population Recommendations
First line ART regimens for • TDF + 3TC + EFV (preferred option)
Adults and Adolescents
• If TDF + 3TC + EFV is contraindicated or not available, one of the
following options is recommended:
14
Table 4:Drugs,form, usual adult dose, food effects and toxicities of the ARVs
used in the guideline
• Second - line ART for adults should consists of two nucleoside reverse transcriptase inhibitors
(NRTIs) + a ritonavir boosted PI:
after failure on a TDF + 3TC -based first line regimen, use AZT + 3TC as the NRTI
backbone in second line regimen,
after failure on an AZT + 3TC based first line regimen, use TDF + 3TC as the NRTI
backbone in second line regimen
• Boosted PI for second line ART is Lopinavir/Ritonavir (LPV/r).
15
Chapter III
Clinical assessment and laboratory tests play a key role in assessing individuals before ART is initiated
and then monitoring their treatment response and possible toxicity of ART.
Clinical Monitoring
Enquiry should be made about (the acronym ABCD):
A - Appetite
B - Body weight
C - Complaints related to ART and OIs
D - Disease progression
Furthermore, at every visit, the patients should be screened for tuberculosis by asking history of:
cough,
fever,
night sweats, and
weight loss.
Laboratory Monitoring
Routine laboratory monitoring should be done including CBC, LFT, RFT, Blood glucose and Serum
lactate to monitor the adverse effects of the drugs, monthly for three months.
Immunological Monitoring
CD4 count should be done at the fourth month of starting therapy and then every six months.
Immunological failure is indicated by a fall of CD4 counts more than 30% from the initial value or a
return to or below pre-therapy baseline.
Virological Monitoring
See goals of therapy for HIV infection (if viral load testing facilities are available)
Monitoring includes
• Pre ART laboratory tests, laboratory test at ART initiation and test when
receiving ART for follow up

Chapter IV
Management for people living with HIV/AIDS at various levels of Health facility
All levels of health care delivery systems in Bhutan can contribute to the management and treatment of
people living with HIV/AIDS (PLHA). The Basic Health Units, District Hospitals and the Referral
Hospitals should work in close coordination in providing comprehensive care and support services.
The membership of the teams should be left to the local decision to appoint most appropriate staffs.
The following are the components of the core team and their respective responsibilities at the hospital
level.
2. Laboratory
Responsibility: The Laboratory will be responsible for doing all the tests and record keeping and report
to DMO.
3. Pharmacy
Responsibility: The Pharmacy will be responsible for providing antiretroviral therapy (ART), ARV stock
keeping, record keeping and reporting to MO/specialist in charge.
The following briefly outlines the scope of care and treatment at each level of health care
system.
20
At Basic Health Unit (BHU) :
a) Patient suspected with HIV/AIDS: If facilities are available for HIV testing, perform a rapid
test after proper counselling. If found reactive, arrange for transfer of sample or refer the
patient to the nearest hospital where arrangements can be made for transfer of samples for
confirmation to the Public Health Laboratory.
If testing facilities are not available and a patient is suspected of suffering from HIV/AIDS
based on signs and symptoms, make arrangement for shipment of samples or patient referral
to the nearest hospital.
b) Patient is already diagnosed to have HIV infection but without signs of AIDS and not on
ART
• Follow up closely (at least three monthly) and advice on healthy living
• Counsel for safe sex and correct and consistent use of condoms
• Screen for TB with the WHO questionnaires
• Record the clinical staging at each visit
• If there are any signs of AIDS or OIs (see clinical staging of HIV infection) the patient
should be referred to the District hospital.
• Fill up the relevant forms and report accordingly to the schedule to the Care ,Support
and Treatment(CST) Unit at JDWNRH
Refer the patient to the District Hospital if there are signs of:
• Drug intolerance/toxicity
• Jaundice
• Losing weight despite treatment
• Opportunistic infections, other complications of HIV and suspicion of any malignancy
21
• Follow the BHU procedures
• Look for evidence of drug intolerance/toxicity
• Refer the patient for CD4 count every six months
22
Chapter V
The Care, Support and Treatment Unit at JDWNRH will serve as the nodal unit to coordinate care and
treatment of PLHAs across the country. It has been set to mainly ensure better coordination and as well
as ensure continuous health services to the PLHAs. Its main responsibilities are
1. Liaising with the Public Health Laboratory to ensure confirmatory test of reactive samples from
district are done timely and results communicated to the Districts
23
2. Assign unique identifier code for newly confirmed HIV positives and enter the record into the
database.
3. Advice and guide delivery of positive results to clients by counsellors in the fields
5. Ensure timely and regular reporting on HIV case follow up to the CST by the districts
7. Coordinate with the Pharmacy Unit, JDWNRH to ensure proper and adequate forecasting of drugs
to ensure a steady supply of ARVs
9. Report quarterly to the National STI & HIV/AIDS on the status of the PLHAs based on indicators
developed by NACP.
10. To discuss in person all the new cases being initiated on ART with the treating physician and those
on ART with specific problems.
* For all recording and reporting forms to CST refer Annex (7).
Chapter VI
CO-INFECTION
Hepatitis B co-infection
Hepatitis B virus infection is an important infection in HIV-infected individuals because of the influence
of HIV on the natural history of HBV infection. HIV/HBV (HBV co-infection) increases the rate of
progression to cirrhosis and liver cancer by four to five folds. The mortality of the patients with the
above situation is approximately ten times higher than that of patients with either infection alone. There
is accumulating evidence that ART greatly reduces progression to cirrhosis and death in coinfection
individuals. As the prognosis of HIV has now dramatically improved the specific consideration for
treatment of individuals co-infected with HIV/HBV has increased its importance.
Treatment
The aim of the HBV treatment is to suppress HBV viral replication and to achieve sustained disease
amelioration and to prevent cirrhosis of liver, liver cell failure and hepato cellular carcinoma. Initiate ART
in all HIV infected individuals who are coinfected with HBV with severe chronic liver disease, regardless
24
of WHO clinical stage and CD4 cell count. In the absence of a severe liver disease ART should be
initiated as per the standard recommendations. The ART regimen should include 2 drugs active against
HBV i.e. Tenofovir and Lamivudine (as in this guideline). This treatment should be continued
indefinitely. The end of point to assess treatment response are:
1. Normalization of ALT
2. Loss of HBeAg with or without the appearance of anti HBeAg and
3. Undetectable serum HBV … by a reliable assay
Hepatitis C co-infection
The significance of hepatitis C virus co-infection in HIV-infected populations has become apparent since
AIDS-related mortality has reduced in the era of ART. Cirrhosis develops in approximately 20% of
patients with chronic HCV infection within 20 years after infection, although the risk for an individual is
highly variable. Risk factors for development of significant liver disease include older age at the time of
infection, male, obesity, and concomitant alcohol use. HIV coinfection adversely affects the course of
HCV infection, resulting in significantly accelerated progression of liver disease to cirrhosis, particularly
those with CD4 cell count < 200 cells/mm3. Unlike HIV and HBV, there is a chance of cure of HCV
infection with specific antiviral.
Treatment
All patients with chronic Hepatitis C should be assessed for treatment with pegylated interferon alpha –
2a plus Ribavirin for 48 weeks. Therapy can be discontinued when HCV RNA is undetectable. The
evaluation and the management of HIV/HCV coinfection should be carried out by an expert in a
specialized centre. The role of a new drug generically known as fosobuvir is promising. The cost of
treatment with this agent is currently an issue.
Chapter VII
OIs are the leading cause of morbidity and mortality in patients with HIV infection. Approximately 80%
of AIDS patients die as a direct result of an infection other than HIV, with bacterial infections heading
the list. While causative agents characteristically are opportunistic organism such as Pneumocystis
jirovecii, Mycobacterium avium complex, CMV and other organisms that do not ordinarily cause disease
in the absence of a compromised immune system, they also include common bacterial and
mycobacterial organisms.
25
Potent ART has decreased the outcome of the OIs, and ART has dramatically improved the prognosis
of HIV.The occurrence of OIs depends on the level of CD4+T lymphocyte count (see figure below)
Prophylaxis:
• Primary: to prevent even first occurrence of infection
• Secondary: to prevent a second occurrence of an infection that has already occurred at least
once (prevention of recurrence).
Mycobacterial infection
Tuberculosis
M. tuberculosis is especially frequent among HIV infected patients. Primary as well as reactivated
disease occur.
Impact of TB on HIV
• TB is the leading AIDS-related opportunistic infection.
• HIV disease progresses more rapidly in patients with TB, the level of plasma viraemia
increases during active TB and successful treatment of tuberculosis brings back the plasma
viraemia to the baseline.
• The lifetime risk of HIV infected patients developing TB is 50% as compared to HIV negative
patients which is 5-10%.
• HIV increases not only the risk, but also the rate of progression of recent or latent M.
tuberculosis infection to disease.
• Increases the incidence of extra-pulmonary/disseminated TB.
26
• HIV increases the incidence of MDR-tuberculosis.
• TB-ART co-treatment involves higher pill burden and increased adverse drug reactions.
• TB/HIV infection is associated with high mortality rate.
TB can manifest at any stage of HIV infection irrespective of the CD4 count. Extra-
pulmonary dissemination is common. In advanced AIDS, clinical and radiological features
of tuberculosis can be atypical.
Diagnosis
• Chest X-ray: classic presentation with apical cavitatory disease
• Sputum AFB for three days
• Culture for AFB (even if the smear is negative)
• To confirm MAC (instead of MTB) blood culture is necessary
• Tuberculin Skin Test (TST): CDC recommends TST using 5 tuberculin units of PPD for HIV
infected person who have not had a prior positive test (induration ≥ 5mm at 24 to 48 hours).
TST should be repeated annually if initial tests were negative. And, also following immune
reconstitution when CD4 count increases to >200/mm3. Positivity of TST decreases with
progression of HIV/AIDS.
• It is important to do a TST for evidence of latent TB in all PLHIVs. It is recommended that any
anergic patient with HIV infection who is at high risk for TB (residents of prisons or jails,
injection drug users (IDU), and homeless individuals) should be given 6 months course of
isoniazid.
Treatment of tuberculosis
12 months’ regimen or longer is recommended for TB meningitis, spinal TB, TB of the bones and military TB
• Household contacts of the patients should be screened for TB with sputum exam for AFB and possible chest X-
ray.
• Patient with active TB should be started on treatment immediately and the patient should be isolated.
• Consider DOT to improve adherence and treatment success.
ART in TB/HIV
• First line:
2NRTIs + EFV (600mg every 24 hours) – TDF + 3TC + EFV
• Alternative line:
Protease inhibitors are not recommended for Rifampicin based anti-tubercular regimen.
27
Mycobacterium avium complex (MAC)
• MAC is an acid fast atypical mycobacterium
• MAC infection probably indicates an acute infection with organisms that are ubiquitous in the
environment in both in soil and water.
• The presumed portals of entry are the gastrointestinal and respiratory tracts.
• MAC infection is a late complication of HIV infection, occurring in patients with CD4 cells count
of <50 cells/mm3
Presentation
Fever, weight loss, night sweats, and diarrhoea with or without abdominal pain.
1. It is a disseminated disease with gastrointestinal, neurological, dermatological and respiratory
manifestations.
Diagnosis
1. Definitive: Blood culture (positive in 90-95%)
2. Probable: By demonstrating the organisms in stool, bone marrow specimen, liver and skin
biopsy.
3. Disseminated MAC should be confirmed by clinical assessment or blood culture as AFB stain
cannot differentiate between MTB and non-tubercular mycobacteria.
4. Pulmonary MAC shows infiltrates on chest X-ray
Treatment Prophylaxis
• Clarithromycin 500mg 12 hourly P.O. or Primary prophylaxis:
Azithromycin 500mg OD plus Ethambutol • CD4 count <50 cells /mm3 in patients who are
15mg/kg P.O. for 12 months. asymptomatic.

• Discontinuation of primary prophylaxis - patients
• Clarithromycin and Azithromycin for this who have responded to ART with increase in CD4
indication can be procured on named patient count to
basis. > 100 cells/mm3 for at least three month.
Prevention of Recurrence
• Patients with disseminated MAC should receive lifelong secondary prophylaxis or maintenance
therapy (unless immune reconstitution occurs following ART) with Clarithromycin (or azithromycin)
plus Ethambutol.
• Discontinuation of secondary prophylaxis- sustained CD4 increase of more than 100 cells per mm3
for ≥ 6 months in response to ART after12 months of therapy for MAC is completed and if there are
no symptoms or signs attributable to MAC.
Viral infection
Cytomegalovirus infection (CMV)
• CMV retinitis occurs frequently and accounts for 85% of CMV disease in patients with AIDS.
• CMV pneumonitis, encephalitis, polyradiculomyalopathy, dementia, oesophagitis and colitis
are other manifestations.
• Usually occurs in patients with CD4<50 cells/mm3.
• Opacifications of retina, areas of haemorrhages, exudates and periphlebitis are the
ophthalmologic findings.

(more than 100-200 cells/mm3) for more than six
months.
Aspergillosis
Diagnosis
Definitive diagnosis requires biopsy of the tissue involved, or positive culture from a normally sterile site.
Probable: Two positive sputum cultures or one positive bronchoscopy in an appropriate host.
Treatment
• Voriconazole is the treatment of choice.
• Amphotericin B, 1.0mg/kg/day IV for 2 weeks.
• Fluconazole 200mg P.O. BD for three days then 400mg per day for a minimum of 2 weeks.
Penicilliosis

(papules, pustules, or nodules).
• Lymphadenopathy and wasting from endemic areas (Northern Thailand and Southern China)
with CD4 count <50 cells/mm3.
• The diagnosis is established by the evidence of pathogen in culture, smear, or histopathology;
most frequent with Wright stain of skin scraping, node biopsy or marrow aspirate. Smears
show elliptical yeast, some with the characteristically clear central septation.
Treatment
Treatment
Preferred regimen:
• Severe - Amphotericin B 0.6mg/kg per day for 2 weeks, then Itraconazole 200mg P.O. BD for 10 weeks.
• Mild to moderately severe - Itraconazole 200mg BD.
Maintenance:
Itraconazole 200mg per day for lifetime or CD4 count more than 100 cells per mm3 for more than 6 months in
response to
ART
32
Other Opportunistic Infections
Protozoal infections
Toxoplasma gondii
• Typically causes multiple CNS lesions and presents with encephalitis and focal neurological
signs.
• The disease represents reactivation of previous infection and the serological test is usually
positive.
Often the diagnosis relies on response to empirical treatment as seen by clinical response and
reduction in the size of the mass lesion.
Imaging: MRI is the best radiographic technique for the diagnosis of cerebral toxoplasmosis
Immunologic Complications
• Acute Inflammatory Demyelinating Polyneuropathy (AIDP)
• Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
• Mononeuropathy
Tubercular meningitis
The treatment regimen of TB meningitis is the same as for immunocompetent host and the
duration of the treatment should be 12 months.
Dysphagia/ Odynophagia
Causes: Candida, CMV, HSV, other fungal infections, TB infection, and drug induced oesophagitis.
Treatment
• Empirical treatment of oesophageal candidiasis is with fluconazole 100 (up to 400mg P.O.) for 14 to 21
days.
• If the patient doesn’t respond, give a course of acyclovir 200-800mg five times a day for 2-3 weeks
(suspected HSV infection).
• If no improvement, patient may be referred for oesophagoscopy to rule out CMV infection which is treated
with Ganciclovir.
Diarrhoea
Diarrhoea is still a common problem in the era of ART. It is caused by organisms like microsporidium,
cryptosporidium, MAC, CMV, E.histolytica, G.lamblia, Strongyloides, Salmonella, Shigella, C. jejuni,
Clostridium species. Idiopathic diarrhoea is common.
Diagnosis
• Stool examination for parasites, fungi, WBC and RBC, and modified AFB stain
• Febrile patients with CD4 counts<100 cells/mm3 need blood culture for MAC infection.
34
Treatment
Treatment
• In acute diarrhoea - Cotrimoxazole or quinolones (short course)
• For chronic diarrhoea - Depending on the suspected aetiology, Cotrimoxazole, quinolones, or
Metronidazole and Albendazole may be used.
• The initiation of ART alone stops diarrhoea in majority of the cases.
Cutaneous manifestations are very common in HIV/AIDS and have a very broad and diverse spectrum.
In this section only those manifestations which are commonly encountered with HIV/AIDS are
considered. They are:
Viral:
• Exanthema of acute retroviral syndrome – maculopapular rashes seen in acute retroviral
syndrome and is self-limiting.
• Chronic herpetic ulcers- usually present as painful orolabial or genital lesions and persist for
more than a month. Acyclovir is the drug of choice.
• Herpes Zoster- vesicular eruptions along the nerve distribution can occur in normal CD4
counts. Acyclovir is prescribed.
• Oral Hairy Leukoplakia (OHL) is caused by the Epstein Barr Virus (EBV). Reported in more
than 20% of HIV patients, and is a marker of HIV infection. It occurs when CD4 count is <
100cells/mm3. Hyperplastic whitish plaques are seen on the lateral sides of the tongue which
are difficult to scrape off as opposed to Candidial lesions of the tongue, oral and buccal lesions
which can be easily scraped off with a tongue depressor. It is usually bilateral and is a
premalignant condition.
• Molluscumcontagiosum: multiple umbilicated follicular lesions which can occur in any part of
the body, except the palms and the soles. No specific treatment is required as initiation of
ART controls the lesions.
Fungal:
Proximal subungualonychomycosis – is a fungal infection of the proximal nail bed. Itraconazole
given in pulse therapy is this management of this condition.
Bacterial:
• Staphylococcusaureus infections
• Impetigo
• Folliculitis
• Furunculosis
• Acne vulgaris
Others:
• Eosinophillic folliculitis- unknown aetiology and pathogenesis; small pink to red,
oedematous, folliculocentric papule occur symmetrically above the nipples. Treatment:
Prednisolone
35
• Psoriasis- It is one of the markers of HIV infection. Existing psoriasis gets flared up with
HIV infection. Treatment is as for the immunocompetent host.
• Pruritic papular eruptions (PPE) - common finding in AIDS patients and is also a marker
of HIV infection. It occurs in patients with CD4 <50 cells/mm3.
• Icthyosis and xerosis are common in advanced HIV infection. These are extremely
pruritic dermatoses characterized by red or skin coloured. Treatment is symptomatic.
Associated Neoplasms
Treatment
Local therapy with liquid nitrogen or intra-lesional injection with alitretenoin or vinblastine has been
used. Cryotherapy or radiation may be useful as well. Systemic therapy involves chemotherapy (e.g.
liposomal doxorubicin, paclitaxel, liposomal daunorubicin, thalidomide, retinoids), radiation, and
interferon α.
Lymphoma
• Lymphomas commonly associated with AIDS are non-Hodgkin’s lymphoma, CNS and
systemic lymphoma, and lymphoma of B-cell origin.
• EBV appears to be the associated virus.
36
Chapter VIII
IMMUNE RECONSTITUTION INFLAMMATORY SYNDROME (IRIS)
Definition
Clinical deterioration following initiation of ART believed to be related to restored ability to mount an
inflammatory response due to restoration of pathogenic specific immunity.
• Also occurs following re-initiation or change to more potent ART.
• It has a temporal association with the initiation of ART (5-6 weeks)
• Commonly known as immune reconstitution syndrome (IRS) also known as immune recovery
syndrome
• Incidence: 17-25% in three large retrospective studies.
Diagnosis
Initiation, re-initiation or change to a more effective combination of ART with associated increase in
CD4 cell count and/or decrease in viral load after excluding:
a. Worsening of known infection due to inadequate or inappropriate therapy.
b. New infections not known to be associated with IRIS (e.g. bacterial sepsis).
c. Reactions to medications.
b. Unmasking IRIS: in which a previously present, but clinically undetected, and therefore
untreated infection, becomes apparent after starting ART, and the clinical presentation is
usually inflammatory in nature.
IRIS prevention
• WHO currently recommends starting ART two weeks to two months after TB treatment
with patients with CD4 cells count<200 cells /mm3 but delaying ART in patients with
higher CD4 cell counts.
• Optimal timing of ART introduction in patients with TB and cryptococcal meningitis is
needed.
• Unmasking forms of IRIS might be prevented by thoroughly screening for OIs and
commencing patients on OI treatment before starting ART.
• Paradoxical IRIS: shorter delay between starting treatment for TB and cryptococosis and
ART has been identified as risk factor, i.e. the chances of developing IRIS is higher if the
interval between initiation of ART and TB treatment or treatment of cryptococosis is short.
Glucocorticoids
• Mortality benefit has been demonstrated for
Bacterial meningitis
TB meningitis
TB pericarditis
Severe typhoid fever
PCPwith moderate to severe hypoxemia
37
Management and treatment of severe IRIS with glucocorticoids
• Glucocorticoid therapy to suppress inflammatory response is the most commonly use
treatment for IRIS.
• Recommended dose of prednisolone is 10-40mg P.O. and 1- 2mg per day and if severe
for 1-2 weeks after which it should be tapered.
• Some patients experience relapse of symptoms when glucocorticoid is tapered or
discontinued in which case, months of treatment may be required.
• In viral hepatitis-associated IRIS, glucocorticoids may cause harm. Their use for this form
of IRIS is ill-advised.
In some patients the potential risks of steroids are high (e.g. patient with Kaposi’s sarcoma),
provided an IRIS does not seem to be life threatening, counselling, reassurance and symptomatic
and supportive management without the use of glucocorticoids is a safer option.
NSAIDs
• NSAIDs may provide symptomatic relief in patients with IRIS manifestations that are not
severe.
• Favourable responses are reported in cryptococcal IRIS with lymphadenitis, MAC IRIS and
paradoxical TB-IRIS.
• The adverse effects of the NSAIDs - GI ulceration and worsening of renal functions in patients
with HIV-associated nephropathy should be borne in mind.
IRIS in TB
For patients with tuberculosis, IRIS has been reported to occur in as many as 30% in the developed
world. The syndrome is characterized by fever, worsening pulmonary lesions (X-ray findings) and
expanding CNS lesions, serositis (pleural and pericardial effusions). Mean duration for development of
the syndrome is about 60 days. These reactions are usually self limiting, although in some cases a
short course of glucocorticoids may be helpful to reduce inflammation for severe respiratory and CNS
symptoms. Initiation of ART can also unmask previously undiagnosed infections by augmenting the
inflammatory response. In general, ART should not be discontinued for immune reconstitution
syndrome.
IRIS in MAC
Symptoms of IRIS in MAC is characterised by increase in symptoms of lymphadenitis and
granulomatous inflammations, cutaneous lesions, endobroncheal tumours, small bowel involvement,
and paravertebral abscess. Cultures are usually negative.
Treatment
• Glucocorticoids 1 mg/kg for one month and then tapering off gradually.
• Appropriate antimicrobial therapy.
• Local surgical drainage where indicated.
IRIS in CMV
IRIS in CMV is seen in the form of:
• Vitreitis, retinitis, retinal detachment, neovascularisation, proliferative vitreo retinopathy.
• Parotitis.
• Pneumonitis.
Treatment
• Topical anti-inflammatory therapy.
• Periocular steroids.
• Ganciclovir implants.
• Prophylactic CMV therapy.
IRIS in Cryptococcosis
Patients suffering from cryptococcosis show increase in intracranial pressure, CSF pleocytosis, high
protein, negative culture, cerebral infarction, enlarged lymph nodes, cavitatory or necrotizing pneumonia
and subcutaneous abscesses in IRIS.
38
Treatment
• Antifungal therapy to lower fungal burden.
• Manage increased intracranial pressure.
• Anti-inflammatory drugs.
IRIS in PCP
IRIS develops early in patients with PCP after startingART (median duration of about 2 weeks if primary
prophylaxis was not received). It presents as granulomatous pneumonitis on X-ray.
Treatment
a. Cotrimoxazole with ART.
b. Symptomatic.
c. Glucocorticoids may be indicated

Chapter IX
Definition
The set of services that are provided to manage the specific aspects of exposure to HIV and help
prevent HIV infection in a person exposed to the risk of getting infected by the HIV.
PREVENTION IS PRIMARY!
Protect patients....protect healthcare personnel.....promote quality healthcare
PEP should be initiated as soon as possible, within hours and no later than 72 hours
Indications
PEP is indicated in the following circumstances:
• break in the skin by sharp object (including both hollow bore and cutting needles or broken
glassware) that is contaminated with blood, visibly body fluids, or other potentially infectious
material, or that has been in the source patient's blood vessel.
• bite from an HIV infected patients with visible bleeding in the mouth that causes bleeding in the
health care worker (HCW)
• splash of blood, visible body fluid or other potential infectious material to a mucosal surface (mouth,
nose or eyes)
• a non intact skin (e.g. dermatitis, chapped skin, abrasions, or open wound) exposure to blood, body
fluid, or other potentially infectious material.
Universal Precaution
• standards developed to prevent exposure and transmission of disease in an occupational
setting
• UNIVERSAL means: everyone everywhere, and always!!
Management
• first aid
• do not panic
• immediate management: wash skin with soap and water and flush mucous membranes with
water
HIV testing
• Enzyme immunoassay (ELISA) - consider rapid test if ELISA cannot be done within 24-48
hours
• Evaluate for infection status with approved rapid HIV antibody test
• Remember to obtain the source persons informed consent and maintain confidentiality
• If exposure source is unknown, information on circumstances, disease prevalence may be
epidemiologically assessed for likelihood of HIV transmission.
41
PEP is NOT indicated:
• If the exposed person is HIV positive from previous exposure
• If the exposure does not pose a risk of transmission
• Exposure of intact skin to potentially infectious body fluids
• Any exposure to non infectious body fluids, faeces, saliva, urine and sweat
• Exposure to body fluids from a person known to be HIV negative unless this person is
identified as being a high risk for recent infection and thus likely to be within the window period
• If the exposure occurred more than 72 hours previously
42
Chapter X
ADHERENCE
Definition
Adherence was defined for the first time as an extent to which patients’ behavior coincides with
medical/health advice. Subsequently it was defined as the extent to which the patients continue with an
agreed mode of treatment.
Adherence to ART has been correlated strongly with HIV viral suppression, reduced rates of resistance,
an increase in survival, and improved quality of life. A low adherence is strongly associated with
detectable viremia, progression to AIDS and death. Because HIV treatment is a lifelong endeavor, and
because many patients will initiate therapy when they are generally in good health, feel well, and
demonstrate no obvious signs or symptoms of HIV disease, adherence poses a special challenge and
requires commitment from the patient and the health care team.

Chapter XI
With the proper inception of the PMTCT program in Bhutan from 2005, the incidence of HIV
transmission from mother to child in the group who received ART prophylaxis is zero till date in the
babies who were tested.
The PMTCT 2013 Guidelines recommends that the ART needs to start early in the course of disease in
all pregnant patients in order to have the greatest impact on disease transmission, morbidity and
mortality. Breast milk transmission can be prevented by replacement feeding.
.
Table 1: Factors that can potentially increase the risk for MTCT at different stages of pregnancy
• Maternal malnutrition
47
Effect of HIV on pregnancy outcomes
Although maternal morbidity and mortality rates are not increased in seropositive asymptomatic women.
First line ART for • TDF + 3TC + EFV is recommended as first-line ART in pregnant women,
Pregnant Women including pregnant women in the first trimester of pregnancy.
• Infants of mothers who are receiving ART should receive six weeks of
infant prophylaxis with AZT (twice daily). Infant prophylaxis should begin
at birth or when HIV exposure is recognized postpartum.
However, reported adverse fetal outcomes include preterm delivery, fetal growth restriction, and
stillbirth were seen more common among HIV-infected women compared with non-HIV infected women.
There are no studies that indicate an increase in the frequency of birth defects related to HIV infection.
HIV is not an indication for termination of pregnancy.
1. Diagnosis/Testing
• All pregnant women attending ANC should be offered HIV testing and counselling
preferably in the first trimester of pregnancy and if missed should be offered during the
subsequent visits.
• Women who had not attended any ANC should be screened for HIV during labour or
immediately after birth
• ANC diagnosis of HIV should be linked with routine MCH service and with involvement of
focal person in each Hospital.
• Repeat testing is recommended in the high risk group between 30-36 weeks.
It is recommended to form a core team at each health facility for PMTCT service as listed below:
• All obstetricians/ physician/Midwife/ANM/AN/HA
• All pediatrician/nurse
• 1-2 trained counselors, according to the local case load
• 1-2 staff nurses
• 1 Lab Technician
• 1 Pharmacist/pharmacy technician
Antiretroviral Therapy
• All the HIV positive pregnant women should be started on ART irrespective of CD4 count
or the WHO clinical stage as soon as possible. They should follow the same regimen like
adults and adolescents (TDF+3TC+EFV).
• Give folic acid (5mg) daily for all women receiving ART before 12 completed weeks
• If the CD4+ T-cell count is <200/mm3, primary prophylaxis for P. jiroveci (formerly P.
carinii) pneumonia is recommended with Sulfamethoxazole-trimethoprim or Dapsone.
48
Management of Labour and delivery
Mode of delivery
• All HIV positive pregnant women will be delivered by elective caesarean section at 39
completed weeks in comprehensive EmOC centers (facilities where C/Section are available).
• Routine vaginal delivery will be promoted once the viral load facilities are available (less than
1000 copies/ml of blood).
• Emergency caesarean section will be offered to all HIV positive mothers coming with labour
or ruptured membranes with less than 4 hours duration.
• All HIV positive mothers coming with labour and ruptured membranes with more than 4 hours
duration should be allowed for vaginal delivery with the following precautions:
a. Avoid episiotomy as far as possible.
b. Reduce the number of internal examination
c. Not to use fetal scalps monitoring.
d. Avoid prolong labour.
e. Avoid instrumental delivery as far as possible.
Postpartum care
• Immediate postpartum care should be like the routine care.
• Give breast milk suppression to the mother as follows:
Tab pyridoxine 100mg-once a day for 5 days.
Advice mother to use firm bra for breast support.
Use Paracetamol for analgesia.
• Subsequent post natal visits should be also like routine ones.
• Teach and explain the mothers to dispose body secretions and fluids properly.
• All mothers on ART should continue for same medication for life long. After six weeks
they should be followed up in adults clinics
49
Chapter XII
Introduction
In the absence of any interventions, about a third of children born to HIV infected mothers will be born
with HIV or infected through breastfeeding. Children born with HIV have very high mortality. They are
over four times more likely to die by the age of two than children born without HIV. The clinical
manifestations of HIV infection in children are different from those in adults. The immune system of
young children, who are infected perinatally, is immature and hence dissemination throughout the
various organs may occur very early. Organs such as the brain may be susceptible to the effects of
the virus in a manner different from the ones observed in adults. Even the pattern of opportunistic
infections in children is different from those in adults. Children tend to suffer from primary infection
while adults are more likely to suffer from reactivation of infection as their immunity wanes in
response to advanced HIV-infection. Therefore it is important to start treatment and management of
infants with HIV as early as possible.
Tests for antibodies do not establish the presence of HIV infection in infants because of transplacental
transfer of maternal antibodies to HIV. Maternal HIV antibody transferred can persist for as long as 18
months in children born to HIV-infected mothers; therefore a virologic test should be used to diagnose
HIV in infants and children younger than 18 months. All infants with an initial positive virological test
result should be started on ART without delay and, at the same time, a second specimen should be
collected to confirm the initial positive virological test result. Currently there are no facilities for
virological test for early infant diagnosis (EID). Arrangements have to be made to ship samples aboard
until the country is able to establish the facilities for EID. Therefore it is imperative that the Care,
Support and Treatment is informed beforehand to organize the possible shipment of samples for EID.
Although HIV antibody test can be reliably used only after 18months in a child to diagnose HIV, it can
however be useful to exclude HIV infection in children. A negative HIV antibody test in a known HIV-
exposed infant can be used for excluding HIV infection if there is no ongoing exposure. However a
child is suspected to have HIV infection if the child exhibits any clinical features as described in WHO
clinical staging. When DNA- PCR test becomes available, we should test the baby’s blood at 4- 6
50
weeks. If not, it is thereafter confirmed by a HIV anti- body testing after 18 months of age.

FINAL RESULT
Other factors that support the diagnosis of severe HIV disease in an HIV sero-positive infant include:
Recent HIV-related maternal death; or advanced HIV disease in the mother;
52
Signs or conditions that may indicate possible HIV infection:
HIV’s clinical expression in children is highly variable. Many HIV-infected children develop severe HIV-
related signs and symptoms in the first year of life. Other HIV-infected children remain asymptomatic or
mildly symptomatic for more than a year and may survive for several years ( rapid and slow progressors
respectively )
Suspect HIV if any of the following symptoms, signs, and/or clinical events are present, as they are not
common in children without HIV:
• Recurrent infection: three or more severe episodes of a bacterial infection (such as pneumonia,
meningitis, sepsis, cellulitis) in the past 12 months.
• Oral candidiasis : After the neonatal period the presence of oral thrush is highly suggestive of HIV
infection when it is occurring when there has been no antibiotic treatment, lasting over 30 days
despite treatment, recurring, extending beyond the tongue, or presenting as oesophageal
candidiasis.
• Chronic parotitis: unilateral or bilateral parotid swelling for >14 days, with or without associated
pain or fever.
• Hepatomegaly with no apparent cause: in the absence of concurrent viral infections such as
cytomegalovirus (CMV).
• Persistent and/or recurrent fever: fever (>38°C) lasting >7 days, or occurring more than once over
a period of 7 days.
• Neurological dysfunction: progressive neurological impairment, microcephaly, delay in achieving
developmental milestones, hypertonia, or mental confusion.
• Herpes zoster (shingles): painful rash with blisters confined to one dermatome on one side.
• HIV dermatitis: erythematous papulular rash. Typical skin rashes include extensive fungal
infections of the skin, nails and scalp, and extensive molluscum contagiosum.
• Chronic suppurative lung disease.
• Signs or conditions very specific to HIV-infected children:
Strongly suspect HIV-infection if the following conditions, which are very specific to HIV, are
present: pneumocystis pneumonia (PCP), oesophageal candidiasis, lymphoid interstitial
pneumonia (LIP), and in girls, acquired recto-vaginal fistula.
• Moderate or severe malnutrition: weight loss or a gradual but steady deterioration in weight gain
from expected growth, as indicated on the child’s growth card. Suspect HIV particularly in
breastfed infants <6 months old who fail to thrive.
Anti-Retroviral Therapy
When to start
Children ART should be initiated in all children infected with HIV below five years of
age, regardless of WHO clinical stage or CD4 cell count.
ART should be initiated in all children infected with HIV five years of age
and older with CD4 cell count ≤500 cells/mm3, regardless of WHO clinical
stage.
ART should be initiated in all children infected with HIV with severe or
advanced symptomatic disease (WHO clinical stage 3 or 4) regardless of
age and CD4 cell count.
53
ART should be initiated in any child younger than 18 months of age who
has been given a presumptive clinical diagnosis of HIV infection.
What to start
First line ART for children • AZT + 3TC + LPV/r (preferred option)
younger than 3 years of age • AZT + 3TC + NVP (alternative option)
First line ART for Children 3 • AZT +3TC + EFV (preferred option)
-10 years of age or >35 Kgs. • AZT +3TC + NVP (alternative option)
In a child with diagnosed or highly suspected HIV infection, the clinical staging system helps to assess
the degree of damage to the immune system, and to plan treatment and care options. The stages
determine the likely prognosis of HIV and are a guide when to start, stop, or switch ARV therapy.
The clinical stages identify a progression sequence from least to most severe (number 1 through 4) -
the higher clinical stage, the poorer the prognosis. For classification purposes, once a stage 3 clinical
condition has occurred, the child’s prognosis will likely remain in stage 3 and will not improve to stage 2,
even once the original condition is resolved, or a new stage 2 clinical condition appears. Antiretroviral
treatment with good adherence dramatically improves prognosis.
The clinical staging events can also be used to identify the response to ARV treatment if there is no
easy or affordable access to viral load or CD4 testing.
(Refer to Annexure 6 for WHO clinical staging)
55
The presence of unexplained persistent diarrhoea places an HIV-infected child into WHO Stage 3
disease, thereby making the child eligible for ART.
Investigations
Investigations that may support a diagnosis are listed below:
Investigation Comment
Stool pH and reducing Stool pH < 5.5 and reducing substances positive suggests
Substances lactose intolerance
CD4 Count/ CD4 % CD4 < 50/mm3: consider Disseminated CMV, Disseminated
MAC
CD4 < 100/mm3:Cryptosporidosis, chronic Microsporidiosis
Hepatomegaly and mildly elevated liver enzymes are common in HIV infected children, though chronic
or progressive liver disease is unusual. Hepatitis could occur in children infected with HIV due to:
Hematological Manifestations
Pediatric HIV disease is associated withdifferent hematological abnormalities presenting as pallor,
neutropenia, lymphopenia, thrombocytopenia and eosinophelia.Thrombocytopenia can be present with
petechiae and ecchymosis and may be diagnosed as Immune Thrombocytopenia. Alteration of
hematological profile occurs due to the virus itself,opportunistic infections,drugs side effects or
antibody mediated cellular destruction.
56
Hematological Abnormalities
Cardiac Manifestation
• HIV infection does not increase the risk of developing congenital cardiac malformations.
However, cardiovascular diseases do seem to develop in HIV-infected children, and they are often
clinically silent.
• The cardiac manifestations include cardiomegally, congestive cardiac failure, non-
bacterial thrombotic endocarditis, cardiomyopathy, pericardial effusion, cardiac tamponade,
conduction disturbances and sudden death.
• Cardiomyopathy is frequently present in patients with encephalopathy. The factors that
have been implicated in the causes of cardiomyopathy include primary HIV disease, immune-
mediated reactions, intercurrent infections and drug toxicity
• Cardiomyopathy decreases the survival rates and is one of the clinical indicators of
starting ARV drugs.
Neurological Manifestation
• Primary CNS infection by HIV is quite common as it is a neurotropic virus.
• Two forms of encephalopathy exist- Progressive and static.
• HIV leads to myriad of CNS problems of varied etiology that are both infectious and non-
infectious.
57
According to the CDC revised system, the diagnosis of encephalopathy requires one of the following
progressive findings to be present for at least 2 months in the absence of other identifiable causes.
• Failure to attain or loss of developmental milestones or loss of intellectual ability, verified
by standard developmental scale or neuropsychiatrical tests.
• Impaired brain growth or microcephaly demonstrated by head circumference
measurements or brain atrophy demonstrated by CT or MRI, with serial imaging required in
children less than 2 years of age.
Acquired symmetric motor deficit manifested by two or more of the following paresis, pathological
reflexes,ataxia or gait disturbances.
• CT may show evidence of cortical atrophy, prominent sulci, and enlarged ventricles
and decreased attenuation of white matter suggestive of progressive
mutifocalleucoencephalopathy.
Nephropathy
• The proportion of HIV-infected children who have nephropathy is variable and is more in
adolescent.
• The manifestations or renal disease associated with AIDS include proteinuria,
hematuria hypertension, renal tubular acidosis, acute renal failure and progression to end-
stage renal disease.
• In the initial stages, the patient could be asymptomatics, although laboratory evidence
of nephropathy can be found on investigations.
• Histological changes inAIDS nephropathy reveal focal segmental glomerulosclerosis,
minimal lesion glomerulonephritis, IgA nephropathy.
• Nephropathy may be due to direct infection of the virus, immune complex vasculitis, or
as a result of various opportunistic infections or drugs.
Prognostic indicators
• In the underdeveloped countries the age at diagnosis and the type of clinical
presentation are the only clinical factors related to prognosis.
• Infants who develop symptoms in the first year of life manifest the fastest progression of
illness with worst outcome.
• Similarly, the occurrence of opportunistic infections, progressive encephalopathy or
hypogammaglobunemia at any age often carries a poor prognosis.
• In contrast, generalized lymphadenopathy, hepatosplenomegaly, parotitisare associated
with a more favorable outcome.
• Viral load is the most important prognostic marker of the risk of progression. But the
availability and the cost are constraints. It is predicted that a favorable clinical outcome is most
likely if virus replication is maximally suppressed before the immune system is
irreversiblydamaged.
All children born to HIV-infected mothers should receive Co-trimoxazole prophylaxis starting at 6 weeks
after birth, or at first encounter with the health care system.
58
When to Discontinue CTX
Group Discontinue Cotrimoxazole
HIV-exposed children Give CTX until HIV infection has been ruled out and the baby is no
longer breast-feeding.
Children less than 5 years Maintain on CTX prophylaxis until age 5 years irrespective of clinical
living with HIV and immune response
HIV-infected children on ART CTX can be stopped only when clinical or immunological indicators
and> 5 years old confirm restoration of the immune system for more than 6 months i.e. in
a child > 5 years of age with a CD4 count of > 500 cell/mm3 on two
occasions not less than 3 months apart (as per adult guidelines
Isoniazid (INH) Preventive Therapy (IPT) for children less than 5 years
An HIV-positive infant or child with no evidence of TB, especially in resource limited settings with high
prevalence of TB, should be given INH preventive therapy to reduce the incidence of TB and death
among these children.
INH should be given for 6 months at a dose of 10mgs/kg/ day to a maximum of 300mgs per day.
All HIV-positive children that successfully complete treatment for TB disease should receive INH for an
additional 6 months.

Nutrition
A child has increased energy needs associated with HIV infection, which requires a proactive approach
to nutritional support after 6 weeks
• From the time of first infection, energy needs increase by about 10%
• In HIV-infected children with chronic conditions such as LIP, persistent diarrhoea, HIV-related
malignancies, and during infections such as TB, energy needs can increase by about 25-30%
• During and following periods of severe malnutrition, energy requirements may increase by 50-
100% in order to recover weight
These increased requirements are over and above normal energy and protein requirements that are
needed by all children to support normal growth and development
In the first two months of life advise the mother to feed at least 8 times in 24 hours. Therefore the
number of feed may be decreased to 6 times in 24 hours.

• Disclosure to children should be done little by little, encouraging questions, providing truthful answers, and
making the child understand they can comeback with more questions at any time.
• Counselling the caregiver for guidance on disclosure of HIV status is important component of the counseling
process. Counselling techniques used should be individualized based on the child’s age, maturity, clinical and
social circumstances; and should facilitate the child’s capacity to cope with their illness.

Chapter XIII
Six classes of antiretroviral agents are currently available for use: nucleoside/nucleotide reverse transcriptase
inhibitors (NRTIs),non nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), fusion
inhibitors, CCR5 receptor antagonists, and integrase inhibitors.
Combinations of three anti-retrovirals typically two reverse transcriptase inhibitors plus either a non-nucleoside
reverse transcriptase inhibitor or boosted protease inhibitor is referred to as highly active antiretroviral therapy
(ART). These drug regimens have produced sustained reductions in viral load often to levels below the limit of
detection, and have been associated with improvements in CD4 cell counts, immune function, and clinical well-being.
Lamivudine (3TC)
(Available as 150mg tablets and 10mg/mL syrups.)
Lamivudine is well tolerated and considered the safest of NRTIs. It is also effective against Hepatitis B virus. Use in
pregnancy is extensive and well established.
Dose
• 150mg BD or 300mg once daily orally; no interaction with food
• Dose adjustment is required with reduced creatinine clearance
Side Effects
• Side effects are minimal
• Infrequent complications include headache, nausea, diarrhoea, abdominal pain and insomnia.
• Class related side effect of lactic acidosis and steatosis are listed but not clear if it can be attributed to 3TC
therapy.
Zidovudine (AZT)
(Available as 300mg tablets and 10mg/mL syrup)
Zidovudine was the first antiretroviral agent to be made available and it still holds an important place as one of the
most widely used antiretroviral agents as a component of ART. It is also used as a monotherapy to prevent vertical
transmission from mother to child.
65
Dose:
• 300mg 12 hourly (>70kg weight) or 200mg 8 hourly
• No interaction with food
Side Effects
Bone marrow suppression (macrocytic anaemia and neutropenia) is a most common serious side effect which occurs
within a few weeks of starting treatment. Other less serious but frequently seen side effects include asthenia, fever,
malaise, dizziness, headache, abdominal pain, anorexia, dyspepsia, taste disturbance, diarrhoea, nausea, vomiting,
and rashes. Class related side effects such as lactic acidosis and severe hepatomegaly with steatosis have been
reported as rare, but can be fatal; myopathy due to mitochondrial toxicity may occur. Pancreatitis, convulsions, and
pigmentation of nails, skin, and oral mucosa may also occur.
Tenofovir (TDF)
(Available as 300mg capsules)
TDF belongs to a distinct class of nucleotide reverse transcriptase inhibitors (NRTIs). It forms the mainstay of triple
regimen in patients with HBV coinfection owing to its established efficacy against HBV.
Dose
• 300 mg once a day orally to be taken with food; the dose of Tenofovir is expressed in terms of its ester
desoproxil fumarate which is equivalent to 136 mg Tenofovir.
• Dose adjustment is required in case of renal impairment as follows:
o Cc 30-49mL/minute, 300mg every 48 hours
o Cc 10-29mL/minute, 300mg twice a week
Side Effects
The most common side effects associated with Tenofovir include nausea, vomiting, diarrhea, and asthenia. Less
frequent side effects include hepatotoxicity, abdominal pain, peripheral neuropathy, myalgia and skin rashes.
Hypophosphatemia is also common. Nephritis, nephrogenic diabetes insipidus, renal impairment, acute renal failure,
and effects on the renal proximal tubules, including Fanconi syndrome is a concern. There have also been reports of
raised liver enzymes, hepatitis, hypertriglyceridaemia, hyperglycaemia and neutropenia.
Precaution
Tenofovir should be used with caution, and doses modified, in patients with renal impairment. Renal function and
serum phosphates should be monitored before treatment is started, every 4 weeks during the first year of therapy,
and then every 3 months; in patients with a history of renal impairment or who are particularly at risk, more frequent
monitoring may be needed.
Nevirapine (NVP)
(Available as 200mg tablets and 10mg/mL syrup)
Nevirapine is one of the most commonly used NNRTI as a component of ART. It is also used for PMTCT.
Dose
66
200 mg once daily for the first 14 days; then increased to 200 mg twice daily if there is no rash. If rash is seen, the
dose should not be increased till the rash resolves. It is readily absorbed after oral administration and has no
significant interaction when taken along with food.
Side effects
The most common adverse effect of nevirapine is skin rash, usually occurring within the first 6 weeks of starting
therapy. Severe and life-threatening skin reactions including Stevens-Johnson syndrome and, more rarely, toxic
epidermal necrolysis have been reported. Severe hepatotoxicity, including hepatitis and hepatic necrosis, has
occurred and may be more prevalent in women and patients with high CD4 cell counts at the start of treatment. Other
common adverse effects include nausea, vomiting, diarrhoea, abdominal pain, fatigue, drowsiness, and headache.
Drug Interactions
• Rifampicin, protease inhibitors and oral contraceptives decrease the level of nevirapine.
• Use of nevirapine with ketoconazole and oral contraceptives is not recommended.
Caution
• Use of nevirapine with ketoconazole and oral contraceptives is not recommended.
• Therapy should be interrupted in patients who developmoderate to severe liver functions test results.
• Therapy should be reinstated with a 14 day once daily dosing when liver function returns to normal.
• If liver function worsens nevirapine should be discontinued.
Efavirenz (EFV)
Available as 600mg tablets
Efavirenz is used as an alternative to Nevirapine when Nevirapine is not tolerated or contraindicated and vice versa.
Dose
As capsules
Adult and child 40kg and over – 600mg OD
Child 33-39 kg - 400mg OD
Child 25-32kg – 350mg OD
Child 20-24kg – 300mg OD
Child 15-19kg – 250mg OD
Child over 3 years / 10 – 14kg – 200mg OD
Bioavailability of Efavirenz from the oral solution is less than that from the capsule and so proportionately higher
doses should be used.
As an oral solution;
Adult and child 40kg and over 720mg OD
Child 33-39 kg – 510mg OD
Child 25-32kg – 450mg OD
Child 20-24kg – 360mg OD
Child 15-19kg – 300mg OD
Child over 3 years / 10 – 14kg – 270mg OD
Dose should preferably be taken at bed time to reduce occurrence of CNS side effects.
67
Side Effects
The most common adverse effects associated with efavirenz are skin rashes and CNS disturbances. CNS symptoms
include dizziness, headache, insomnia or somnolence, impaired concentration, abnormal dreaming, and convulsions.
Symptoms resembling psychoses and severe acute depression have also been reported. Other adverse effects
include nausea and vomiting, diarrhoea, fatigue, and pancreatitis. Raised liver enzyme values have been noted,
particularly in patients with viral hepatitis. Raised serum-cholesterol and -triglyceride concentrations have been
reported.
Precautions
• Efavirenz is contra-indicated in patients with severe hepatic impairment, and should be used with caution,
and liver enzymes values monitored, in patients with mild to moderate liver disease.
• Caution should be exercised in patients with a history of seizures or psychiatric disorders. Efavirenz should
be discontinued if a severe skin rash, associated with blistering, desquamation, mucosal involvement, or
fever, develops.
• Monitoring of plasma-cholesterol concentrations may be considered during Efavirenz treatment.
Drug Interactions
Efavirenz both induces and, to a lesser extent, inhibits the cytochrome P450 enzyme system, exerting a variable
effect on concentrations of concurrently administered drugs that utilize this enzyme system.
Lopinavir/Ritonavir (LPV/r)
Available as 200/50mg tablets or 400/100mg
LPV/r is a co-formulation of Lopinavir and Ritonavir, in which ritonavir acts as a pharmacokinetic enhancer (booster).
Dose
Adults: 400/100mg twice a day to be taken after meals
Side Effects
Diarrhoea in 15-25% nausea and abdominal pain, class side effects: insulin resistance, fat accumulation and
hyperlipidemia, elevated trasaminases.
Drug Interactions
Drug interactions with PIs are numerous and difficult to predict. Ritonavir is the most potent inhibitor of liver enzymes
and is most likely to reduce the hepatic metabolism.
• Plasma concentration of Lopinavir decreased with Efavirenz and Nevirapine; once a day dosing of LPV/r
may not suffice
• Concentration of Lopinavir decreased with Rifampicin
• Concentration of clarithromycin increased; dose reduction should be considered in renal failure
• Concentration of atorvastatin increased; uselowest possible dose of 10mg/day or use alternatives such as
pravastatin,
68
• Concentration of hormonal contraceptives decreased, use alternative contraception.
• Increases concentration of ergot alkaloid; may lead to ergotism
Amphotericin B
(Powder for injection: 50mg vial)
Indications
• Oesophageal and oral candidiasis resistant to azole derivative.
• Cryptococcal meningitis.
• Histoplasmosis and coccidioidomycosis.
• Aspergillosis and penicillinosis.
Dose
• Oesophageal and oral candidiasis : 0.5- 1mg/kg/day until symptoms resolve.
• Histoplasmosis and coccidioidomycosis: 0.5-1mg/kg/ day for at least 6 weeks.
• Penicillinosis: 0.6 - 1mg/kg/day for 7-14 days or until there is clinical resolution.
Side Effects
Common adverse effects which occur during or following intravenous infusion of amphotericin B include headache,
nausea, vomiting, chills, fever, malaise, muscle and joint pains, anorexia, diarrhoea, and gastrointestinal cramp.
Hypertension, hypotension, cardiac arrhythmias including ventricular fibrillation and cardiac arrest, skin rashes,
flushing, anaphylactoid reactions including bronchospasm and dyspnoea, blurred vision, tinnitus, hearing loss,
vertigo, gastrointestinal bleeding, liver disorders, peripheral neuropathy, and convulsions have been reported
occasionally. Partial reversible deterioration of renal function, progressive normochromic anaemia and
thrombocytopenia are less common.
Precautions
Concomitant administration of other nephrotoxic drug should be avoided.
Indications

Dose
• Treatment of MAC infection; 500mg once daily until the symptoms resolve
• Prophylaxis: 1.2g once a week indefinitely
• To be taken on empty stomach one hour before food or two hours after
Side Effects
Gastrointestinal disturbances such as abdominal discomfort and cramp, nausea, vomiting, and diarrhoea are
common but not as severe as erythromycin. Severe hypersensitivity reactions and photosensitivity occur rarely.
69
Transient reductions in neutrophil counts have been seen in patients receiving azithromycin. Pain and inflammation
may occur at the site of intravenous infusions.
Fluconazole
(100mg tablet, Oral suspension 10mg/ml)
Indications
• Treatment and prophylaxis of cryptococcal meningitis: Following treatment with amphotericin B either for
two weeks or until the condition improves fluconazole 800mg oral or intravenous for 2 days followed by
400mg once a day for 8 weeks and then reduced to 200mg OD.
• Treatment of oesophageal and resistant oropharyngeal candidiasis: 200mg initial loading dose followed by
100mg once a day until the symptoms resolve.
• Vaginal candidiasis: 150mg stat
• Treatment and maintenance of coccidiodomycosis: 400mg orally in patients not tolerating amphotericin B.
Side Effect
Gastrointestinal tract side effects such as abdominal pain, diarrhoea, flatulence, nausea and vomiting, and taste
disturbance are common. Other adverse effects include headache, dizziness, leucopenia, thrombocytopenia,
hyperlipidaemias, and raised liver enzyme values. Serious hepatotoxicity has been reported in patients with severe
underlying disease such as AIDS or malignancy.
Drug Interactions
Dose should be increased by half if co administered with Rifampicin.
Ganciclovir
(Capsule 250mg, Powder for injection 500mg/vial)
Indications
Treatment of cytomegalovirus end organ disease: 5mg/kg by slow IV infusion twice a day for two to three weeks or
until the symptoms resolve. Treatment and maintenance of CMV retinitis: 5mg/kg by slow IV infusion twice a day for
two to three weeks followed by maintenance dose of 5mg/kg once a day.
Side Effects
The most common adverse effects of intravenous Ganciclovir are haematological and include neutropenia and
thrombocytopenia; anaemia also occurs. Other adverse effects occurring in patients given intravenous Ganciclovir
include fever, rash, and abnormal liver function tests. Irritation or phlebitis may occur at the site of injection due to the
high pH.
The patient should be counselled in detail on the potential side effects, so that he or she is in a position to recognize
them and to consult his physician in time. This can save livesand prevent the irreversible damage of side effects,
such as polyneuropathythrough early diagnosis. Some of the notable side effects of ART are highlighted as follows:
Lactic Acidosis
70
Lactic acidosis is a rare but life-threatening complication attributed to NRTIs. NRTIs are thought to cause
mitochondrial toxicity via inhibition of the mitochondrial DNA polymerase. It occurs most frequently on treatment with
Stavudine (no longer used in Bhutan), less in patients on Zidovudineand lamivudine.
The clinical symptoms, including fatigue, nausea and vomiting, abdominal pain, weight loss and dyspnoea, are non-
specific and may develop acutely or more gradually. Blood results show elevated lactate levels with or without
metabolic acidosis. CPK, LDH, lipase, amylase, γGT and the anion gap may be increased; serum bicarbonate may
be decreased.
Risk factors are obesity, female, pregnancy and therapy with ribavirin or hydroxyurea, a diminished creatinine
clearance, acquired Riboflavin and thiamine deficiency and a low CD4 cell nadir.
Management
• Warrants discontinuation of NRTIs
• Monitor in intensive care unit
• Correct acidosis with IV sodium bicarbonate
• Assist respiratory chain function with riboflavin and thiamine.
Lipodystrophy
Lipodystrophy, also referred to as “fat redistribution syndrome”, consists of two components thatmay be seen
together or independently: fat accumulation and fatatrophy. Fat accumulation is seen within the abdominal
cavity(Crix-belly), the upper back (buffalo hump), and the breast (gynaecomastia). Sometimes patients may have
cushingoid appearance despite the absence of measureable abnormalities in adrenalfunction. Another feature of fat
redistribution is lipoatrophy with loss of buccal fat, and thinning of extremities and buttocks. Fat accumulation is
frequently associated with Pl therapy while lipoatrophy is more closely linked with NRTI therapy, especially d4T/ddI
combination.
Peripheral polyneuropathy
Peripheral polyneuropathy is mainly caused by the NRTIs mainly Zalcitabine, Didanosine and Stavudine. It usually
presents with a distal symmetrical distribution and sensorimotor paralysis. Patients complain of paresthesia and pain
in their hands and feet, and often, with Zalcitabine (not used in Bhutan), about perioral dysesthesia. The symptoms
often begin gradually after several months of therapy. HIV infection itself can lead to peripheral polyneuropathy, but
the drug-induced form becomes apparent much earlier and may develop within a shorter period of time. Patients
must be informed that they should consult their treating physician as soon as possible if the typical complaints
develop. This adverse effect is now less of a longer a concern since we do not use any of the drugs that causes this
side effect.
71
Additional risk factors for polyneuropathy, such as vitamin B12 deficiency, alcohol abuse, diabetes mellitus,
malnutrition, or treatment with other neurotoxic drugs, e.g. INH, should be addressed in the appropriate manner. The
nucleoside offending NRTI should be avoided in such cases.
Hyperlipidemia
Changes in triglycerides and/or cholesterol blood levels havebeen observed very frequently, even in the absence of
fat redistribution. It is an important concern with ART, due to the potential for premature arteriosclerosis and coronary
artery disease. With PI based regimen there is usually an increase in triglycerides, cholesterol, and LDL cholesterol.
Triglyceride levels may increase to > 1000mg/dl, levels associated with an increased riskof both pancreatitis and
arteriosclerosis.
Lipid profile should be monitored every six months and risk assessment done atleast once a year.
Risk factors
Assessment needs to include a review of other cardiovascular risk factors:
• History of arteriosclerosis (stroke, coronary artery disease)
• Hypertension (need for anti-hypertensives)
• HDL cholesterol less <40mg/dl
• Family history
• Age
Management
• Initiate non-drug therapy unless there are extreme elevations
• Switch from PI based regimen to Nevirapine based; Efavirenz is less effective
• A suitable lipid lowering agent should be used
Allergic Reactions
Allergic reactions are frequent during ART. They occur with all NNRTIs, as well as with NRTI and some PIs.
The NNRTI allergy is a reversible, systemic reaction and typically presents as an erythematous, maculopapular,
pruritic and confluent rash, distributed mainly over the trunk and arms. Fever may precede the rash. Further
symptoms include myalgia (sometimes severe), fatigue and mucosal ulceration. The allergy usually begins in the
second or third week of treatment. Severe reactions such as the Stevens-Johnson syndrome, toxic epidermal
necrolysis (Lyell’s syndrome) or anicteric hepatitis are rare. Treatment should be discontinued immediately in cases
with mucous membrane involvement, blisters, exfoliation, hepatic dysfunction (transaminases > 5 times the upper
limit of normal) or fever > 39°C.
Management
Approximately 50 % of NNRTI allergies resolve despite continuation of therapy. Anti-histamines may be helpful.
Prophylactic treatment with glucocorticosteroids or anti-histamines has been shown to be of no benefit for the
72
prevention of Nevirapine allergy. Following a severe allergic reaction, the drug responsible for the reaction should
never be given again.

• It is preferable to use an age-appropriate fixed dose combination for any regimen if such a formulation is
available.
• Oral liquid or syrup formulations should be avoided where possible, especially if volumes are large – such as
above 10 ml.
• Dispersible tablets (or tablets for oral solution) are the preferred solid oral dosage forms, since each dispersible
tablet can be made into liquid at the point of use.
• In general, young children should be switched to available solid oral dosage forms as soon as they are tolerated.
• Where children have to use adult formulations, care must be taken to avoid underdosing. Adult tablets that are
scored are more easily split. For tablets that are not easily split, WHO recommends that this be done in the
dispensing pharmacy using appropriate tablet cutters.
• Some tablets such as LPV/r heat-stable tablets are made in a special embedded matrix formulation (a
proprietary melt extrusion technology that stabilizes drug molecules that are normally heat labile) and should not
be cut, split or crushed, since they lose bioavailability.
• Different dosing between morning and evening doses should be avoided where possible.
• Children have to be weighed at each clinic visit, and dose changes are required as children grow and/or gain
weight.

recommendations for use of EFV in this age group.
b The double-scored tablet has two score lines on one side of the tablet and one score line on the other side, enabling the tablet to be divided into thirds and
halves as needed.

a NVP dose escalation with half dose for 2 weeks when initiating ART is still recommended to avoid toxicity from high initial NVP levels. However, secondary
analysis from the (CHAPAS) -1 trial recently suggested
that younger children have a lower risk of toxicity, and consideration can be given to starting with a full dose. More definitive evidence is expected from an
ongoing trial.
b LPV/r liquid requires a cold chain during transport and storage. The LPV/r heat-stable tablet formulation must be swallowed whole and should not be split or
