Abstract

Long-term (>12 months follow-up) virologic data of children receiving antiretroviral therapy (ART) in Sub-Saharan Africa are limited. Data from rural areas are especially scarce. The aim of this study was to evaluate the long-term virologic outcome of a pediatric cohort in rural South Africa. We performed a retrospective, observational cohort study, including children who initiated ART at least 1 year before data-analysis. Regular monitoring, including HIV-RNA testing, was performed. Genotypic resistance testing was done for children with virologic failure (HIV-RNA >1000 copies/mL). Logistic regression analysis was used to determine predictors of virologic failure. A total of 101 children were included. Median duration since beginning ART was 31 months. Overall patient retention-rate was 76% (77/101), with early mortality being the main cause of attrition (13/24, 54%). Initial immunologic and virologic responses were excellent. However, 38% (31/81) of children subsequently experienced virologic failure. Correlation between virologic failure and immunologic decline was nearly absent. At the time of failure, multiple non-nucleoside reverse transcription inhibitor-associated mutations were observed in 52% (12/23) of children. No d...Continue Reading
