AB Productive infection of the central nervous system by HIV predominantly
involves the white matter and basal ganglia. Involvement of the cerebral
cortex with neuronal loss is also described in AIDS patients but not in
asymptomatic HIV-positive patients. The mechanism of neuronal damage is
unknown. To enquire whether neuronal loss in AIDS may be due to an
apoptotic process, we examined the cerebral cortex from 12 patients who
died from AIDS using two different methods: in situ end labelling and
gel electrophoresis of DNA to demonstrate DNA fragmentation. None of the
patients had cerebral opportunistic infection or tumour. Four patients
had no significant neuropathological changes, eight patients had
variable cerebral atrophy and four of them also had productive HIV
infection of the brain. These patients were compared with four
HIV-positive asymptomatic patients, five seronegative asymptomatic
controls, and two seronegative patients with Alzheimer's disease. We
demonstrated neuronal apoptosis in the cortex in all AIDS patients, as
well as in the Alzheimer's patients. Apoptosis was not observed in the
asymptomatic cases whether seropositive or seronegative. Neuronal
apoptosis was more severe in atrophic brains, and did not directly
correlate with productive HIV infection, suggesting an indirect
mechanism of neuronal damage is most likely.
