Outcome of highly active antiretroviral therapy in HIV-infected Indian children

Abstract

Background: With the advent of highly active antiretroviral therapy (HAART), HIV infection has become a chronic condition in children with improved survival and quality of life. Reports on long term effectiveness of non-nucleoside reverse transcriptase inhibitor based HAART in HIV-infected children in developing countries are limited.

Methods: A chart review was conducted and children who received at least six months of HAART between 2004-2011 at All India Institute of Medical Sciences (AIIMS), Delhi were included. The clinical, immunological and virological responses to HAART were documented. Factors predicting non-adherence and non-response to treatment were described.

Results: One seventy five children (boys: 74.9%) were included in the study, with a median follow up of 43 (IQR: 17, 68) months. The median age at diagnosis was 119 (IQR: 75, 156) months. The median CD4 count at start of HAART was 340 cells/μL (IQR: 185,704), which increased to 924 cells/μL (IQR: 591,1278) at 48 months after HAART and plateaued at 749 (IQR: 542,1056) cells/ μL after 90 months of therapy. The weight for age (WAZ) and height for age (HAZ) z score both showed improvement with time after HAART initiation [baseline: WAZ -2.8 (IQR: -4,-1.6), HAZ -2.1 (IQR: -3.4,-0.69); at 42 months of therapy: WAZ -1.2 (IQR: -2.1, 0.01), HAZ -0.75(IQR: -1.6,-0.37)]. Adverse events were reported in 21 (12%) children. Non-adherence to therapy, treatment failure and death were noted in 35 (20%), 9 (5.1%) and 6 (3.4%) children respectively.

Conclusions: Our experience shows that HAART in HIV-infected children is effective, safe and is associated with good immunological and virological response as well as improvement in growth parameters.
