Abstract: OBJECTIVE: To determine the timing, extent, severity, and persistence of neurologic abnormalities in children with perinatally acquired human immunodeficiency virus 1 (HIV-1) infection compared with similar uninfected children of HIV-1-infected women and control children. METHODS: Serial neurologic examinations and head circumference measurements were performed on a cohort of HIV-1-infected children born to HIV-1-infected women, seroreverting children born to HIV-1-infected women, and control children born to uninfected women. Examination data from 32 HIV-1-infected children, 99 reverters, and 116 control children were summarized by eight neurologic domains. Data were analyzed by longitudinal analysis. RESULTS: Reverter children were not different from control children in neurologic function for any of the eight domains or head circumference. HIV-1-infected children had significantly more neurologic problems than the control and reverter children for seven of the eight domains. The HIV-1-infected children were further classified by whether they had acquired immunodeficiency syndrome (AIDS)-defining clinical conditions (other than lymphoid interstitial pneumonitis) in the first 24 months of life (the AIDS-opportunistic infection group) or did not (the infected-other group). Neurologic abnormalities were early, severe, pervasive, and persistent in the AIDS-opportunistic infection group, and nearly all in this group had head circumference measurements below the 10th percentile. The infected-other group had no statistically significant differences from the uninfected children, although individual children in the infected-other group had some abnormalities. CONCLUSIONS: In utero exposure to HIV-1 without infection seems to have no negative impact on neurologic function in children in the first 2 years of life. Among children with perinatally acquired HIV-1 infection, the most severe and pervasive neurologic problems occur in those children who have early serious HIV-1 clinical disease. Most children without serious AIDS-defining clinical conditions in the first 2 years of life are also free from serious neurologic problems during that period.
