Abstract
This study evaluated the relation between cerebrospinal fluid (CSF) mononuclear cells (MNC) and CSF HIV-1 RNA levels. HIV-1 RNA levels in plasma and CSF were analyzed by reverse transcription-polymerase chain reaction (RT-PCR) in 58 consecutive patients with neurologic symptoms and late HIV-1 infection. The majority of the patients had no central nervous system (CNS) complication (n = 36), 11 had AIDS dementia complex (ADC) and 11 had CNS opportunistic infection (CNS OI). CSF cell counts were analyzed using a method that also evaluated hypocellular CSF (i.e., from 0.1 × 106 cells/L). A strong correlation was found between CSF MNC and CD4+ lymphocyte counts in blood (r = 0.58; p r
