HIV1-Ag in cerebrospinal fluid during AIDS.
HIV infection may display neurological symptoms at any stage; the virus can be isolated from the cerebrospinal fluid (CSF) of both symptomatic and asymptomatic patients and of two third of patients with AIDS. This study sought to determine the sensitivity of HIV1-Ag in the CSF of an HIV-Ab positive population to evaluate its diagnostic and/or prognostic significance. CSF HIV1-Ag was dosed in 48 patients: 9 patients belonged to the III CDC group, 2 to group IVA, 1 to IVB and 36 to IVC1. In the last group, 14 patients had not opportunistic infections of the CNS. The tests proved positive in: 1 IVB patient and 16 IVC patients with focal lesions of the CNS or cerebral atrophy; HIV1-Ag was present in the CSF of 63% of patients displaying neurologic symptoms and it reached 84% in patients with diffuse CNS pathology.
