Serum and cerebrospinal fluid (CSF) samples from asymptomatic patients seropositive for human immunodeficiency virus (HIV) showed frequent evidence of intrathecal IgG synthesis and oligoclonal IgG bands, with different isoelectric focusing patterns in serum and CSF; 2 of 7 had a CSF pleocytosis. The results suggest frequent, early, chronic central nervous system infection following HIV infection.
