Human immunodeficiency virus type-1 (HIV-1) antigen was assayed in paired
serum/cerebrospinal fluid (CSF) specimen from 85 adults and 58 children
with acquired immunodeficiency syndrome and was compared with clinical
neurological status. A quantitative comparison of HIV-1 antigen levels in
matched serum and CSF specimens indicated that HIV-1 antigen expression in
these compartments is independent and is correlated with acquired
immunodeficiency syndrome dementia complex in adults and progressive
encephalopathy in children. In a longitudinal study (n = 47), 16 patients
tested positive for HIV-1 antigen in the CSF before (n = 2) or coincident
(n = 14) with neurological deterioration. Six patients who tested positive
for HIV-1 antigen in the CSF remained neurologically normal for a median
duration of follow-up of 11 months. Six of 25 patients who tested negative
for HIV-1 antigen in the CSF, subsequently showed neurological
deterioration. These data indicate that HIV-1 antigen expression in the CSF
is not useful in predicting neurological deterioration.
