title: Cerebrospinal fluid cytokines in AIDS dementia complex.
abstract: We evaluated cerebrospinal fluid (CSF) and serum concentrations of interleukin-1-alpha (IL-1-alpha), interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) in 30 patients with AIDS dementia complex (ADC), and in 20 HIV-seronegative subjects with other neurological diseases (OND). CSF TNF-alpha, IL-1-alpha and IL-6 were more frequently detectable in ADC patients than in OND subjects. These cytokines were also detectable in CSF of ADC patients with minimal symptoms. In contrast, the majority of both ADC and OND patients did not contain detectable serum levels of cytokines. Our data support the notion of intrathecal synthesis of cytokines in ADC patients and raise the possibility that activated macrophages may play a significant role in the pathogenesis of ADC.
