2. HIV infection is not the end of life. People can lead a healthy life for a
long time with appropriate medical care. Anti-retroviral therapy
(ART) effectively suppresses replication, if taken at the right time.
Successful viral suppression restores the immune system and halts
onset and progression of disease as well as reduces chances of
getting opportunistic infections – this is how ART is aimed to work.
Medication thus enhances both quality of life and longevity.
Adherence to ART regimen is therefore very vital in this treatment. Any
irregularity in following the prescribed regimen can lead to resistance to
HIV drugs, and therefore can weaken or negate its effect.
3. WHO Clinical Staging Recommendations
HIV Infected Adults & Adolescents
Clinical Stage I and II Start ART if CD4 ≤ 500
Clinical Stage III and IV Start ART irrespective of CD4 count
All Pregnant / Breast Feeding Women
All clinical Stages Start ART irrespective of CD4 count
HIV-TB Co-Infected Patients
Patients with HIV and TB co-infection
(Pulmonary or Extra Pulmonary)
Start ART irrespective of CD4 count
Start ATT first, initiate ART as early as possible
between 2 weeks-2months.
For patients with CD4 below 50, ART might be
initiated simultaneously with ATT with strict
clinical and laboratory monitoring
HIV-Hepatitis B/C Co-Infected Patients
HIV and HBV / HCV co-infection – without any
evidence of severe chronic liver disease
Start ART if CD4 ≤ 500
HIV and HBV / HCV co-infection – with evidence
of severe chronic liver disease
Start ART irrespective of CD4 count
7. First-line ART:
First-line ART is the initial regimen prescribed for an ART naĂŻve
patient when the patient fulfills national clinical and laboratory
criteria to be initiated on ART.
(Current NACO treatment guidelines for First-line ART
recommend three drug combination therapy from two classes of
ARV drugs for initial treatment i.e. 2 NRTI + 1 NNRTI)
Second-line ART:
Second-line ART is the subsequent regimen used in sequence
immediately after First-line therapy has failed.
(Current NACO treatment guidelines recommend use of
Ritonavir-boosted protease inhibitors (bPIs) supported by two
agents from the NRTI class, of which at least one should be new.

10. • Patients on EFV due to concomitant ATT need to be substituted
with NVP two weeks after completion of ATT or in the next clinic
visit. No lead in dose for NVP required in such patients.
• If NVP is discontinued for > 2 weeks, while re-starting NVP, one
has to use a lead-in dose for 2 weeks.
• Patients on AZT based regimen to be substituted with TDF, if they
develop anaemia.
• For patients with TDF toxicity, use AZT containing regimen if not
anaemic, d4T if anaemic (e-approval from SACEP required for d4T
as supply of d4T is limited).
• Patients who have developed AZT induced anaemia in the past
should not be re challenged with AZT again.
• Patients who developed severe NVP hypersensitivity (SJS and TEN)
in the past should not be re-challenged with NVP again.
11. The NACO standard Second line regimen (TDF + 3TC + ATV/r) (for those
on AZT/d4T in First line regimen) aims to achieve viral suppression for as
long as possible, so that survival can be prolonged.
