 AB    We quantitated the brain viral burden in autopsy material from AIDS
       patients with and without HIV encephalitis. Central nervous system (CNS)
       samples from 45 AIDS autopsies with less than 48 hours postmortem
       autolysis and without significant non-viral opportunistic infections
       were analyzed using immunocytochemistry (ICC), antigen capture assay
       (ACA) and polymerase chain reaction (PCR). Approximately three-quarters
       of the cases contained HIV DNA by PCR. The majority of these had
       abundant gp41 detected by ICC, but approximately one-third had no HIV
       p24 detected by ACA. With all assays, HIV proteins and DNA were most
       abundant in deep gray matter. Approximately one-quarter of the cases
       contained HIV p24 by ACA in both CNS tissue and cerebrospinal fluid. In
       more than half of the cases cytomegalovirus was detectable in the brain
       by PCR, however, only in the basal ganglia of one case was human herpes
       virus-6 detectable by PCR. In conclusion, HIV infection of the CNS was
       observed in the majority of AIDS autopsies, however, the quantity of
       virus was variable between cases and within different neuroanatomical
       regions. Differences between the quantitation methods could be either
       technical or biological, however, any of them could be used to compare
       assessment of HIV burden by different laboratories.
