Abstract
BACKGROUND\nSETTING\nMETHODS\nRESULTS\nCONCLUSIONS\nIn utero exposure to nucleoside reverse transcriptase inhibitor (NRTI)-containing antiretroviral treatment (ART) regimens may be associated with poor neurodevelopmental functioning in children of HIV-infected mothers. We investigated neurodevelopmental outcomes of HIV-exposed uninfected (HEU) children of HIV-infected women enrolled in a randomized trial of abacavir/zidovudine/lamivudine (triple-NRTI regimen) vs. lopinavir/ritonavir/zidovudine/lamivudine [dual-NRTI + protease inhibitor (PI) regimen].\nThe Mma Bana randomized trial was conducted in urban and rural sites in Botswana.\nThe Mma Bana study randomized HIV-infected pregnant women with CD4 ≥200 cells per mm to a triple-NRTI vs. dual-NRTI + PI regimen from 26- to 34-week gestation through planned weaning at 6-month postpartum. Partway through the study, neurodevelopmental assessments were added at 24 months of age, including the Developmental Milestones Checklist, the Bayley Scales of Infant and Toddler Development third edition, Ten Questions Questionnaire, and Profile of Social Emotional Development. We evaluated differences in mean scores between the 2 arms using unadjusted and adjusted linear regression.\nA total of 197 HEU infants (48% male) completed a neurodevelopmental assessment (101 in triple-NRTI arm and 96 in dual-NRTI + PI-exposed arm). Mean values for all neurodevelopmental outcomes were similar for children of mothers randomized to either ART regimen, with no significant differences in either unadjusted or adjusted models (estimated effect sizes ranging from -0.12 to 0.14).\nNeurodevelopmental outcomes in 24-month-old HEU children of HIV-infected mothers with baseline CD4 ≥200 were similar in those randomized to a dual-NRTI + PI-based vs. a triple-NRTI-based ART regimen, suggestive of lack of short-term toxicity. Monitoring of long-term toxicity and newer regimens is warranted.
