N2 - We have measured levels of soluble interleukin-2 receptor (sIL-2R) and soluble CD8 (sCD8) in serum and cerebrospinal fluid (CSF) of 127 human immunodeficiency virus (HIV)-seropositive and 51 HIV-seronegative individuals. Serum levels of sIL-2R and sCD8 were higher in HIV+ than in HIV- individuals. HIV+ individuals were grouped by neurological status: asymptomatic, abnormal on neuropsychological screening, HIV-related meningitis, inflammatory demyelinating polyneuropathy, opportunistic central nervous system (CNS) infections and HIV-related dementia, myelopathy or sensory neuropathy. Serum levels of sIL-2R and sCD8 were higher in all HIV+ categories compared to HIV- individuals. Patients with HIV-related meningitis had higher levels of sIL-2R and sCD8 than asymptomatic HIV+ individuals, and inflammatory polyneuropathy patients had higher levels of sCD8. CSF levels of sCD8 were higher in all categories of HIV+ than in HIV- individuals. Patients with HIV-related meningitis, inflammatory neuropathy and opportunistic infections had higher levels than asymptomatic individuals. Examination of the time course showed that serum and CSF levels of sIL-2R and sCD8 increased to very high levels during acute HIV infections. Serum levels then declined over several months to relatively stable elevated levels. By 1-2 years after HIV infection sIL-2R was relatively low in CSF, while sCD8 ramained elevated with a gradual decrease over the subsequent years of follow-up.
