Zusammenfassung:Although the effects of highly active antiretroviral therapy (HAART) have resulted in substantial improvements in the systemic health of patients with HIV infection, concerns remain that these medications, which cross the blood-brain barrier poorly, may have a less beneficial effect on nervous system function. This raises the possibility that there may be a progressive long-term decline in neurologic function in patients with adequate systemic response. In a prospective longitudinal study, subjects were evaluated immediately before instituting HAART. Forty-eight subjects underwent ultrasensitive HIV RNA quantitative evaluation of both plasma and cerebrospinal fluid as well as neurologic and neuropsychological examinations. They were reevaluated 6 months after treatment initiation while receiving stable HAART. Both plasma and cerebrospinal fluid viral levels significantly declined after treatment. There was significant improvement in neurologic and neuropsychological functioning after HAART. These results indicate that despite the poor central nervous system penetration of most of these agents, there is satisfactory short-term improvement in both central nervous system viral burden and nervous system function with HAART. However, because treatment failure is increasingly likely over time, continued longitudinal evaluation of this group of subjects is required.
