PG - 383-6 AB - Interleukin-18 (IL-18) is a proinflammatory cytokine released by macrophages that strongly stimulates the production of interferon-gamma, thereby linking innate and acquired immunity. Its role in human immunodeficiency virus (HIV) pathogenesis is under debate and little is known about its role in neuro-AIDS (acquired immunodeficiency syndrome). Serum and cerebrospinal fluid (CSF) levels of IL-18 were determined by a commercially available enzyme-linked immunosorbent assay (ELISA) in 22 HIV-seropositive patients without neurological symptoms (HIV+), 21 patients with AIDS dementia complex (ADC), and 31 patients with AIDS-defining opportunistic infections (OIs) of the brain. Thirty-two HIV seronegative patients (HIV-) served as controls. Compared to HIV- controls, serum IL-18 levels were increased in HIV+ and ADC but not in OI patients. In contrast, CSF IL-18 levels were elevated in OI patients whereas HIV+ and ADC patients were not different from HIV- controls. We provide evidence for an significantly increased IL-18 level in the CSF of HIV+ patients with cerebral OIs, suggestive of a role for IL-18 in the intrathecal host response to OIs.
