Interleukin-6 and granulocyte macrophage-csf in the cerebrospinal fluid from hiv infected subjects with involvement of the central nervous system

Interleucina-6 e granulócito-macrófago-CSF no líquido cefalorraquidiano de pacientes infectados por HIV com comprometimento do sistema nervoso central

We detected the cytokines interleukin-6 (IL-6) and granulocyte macrophage-CSF (GM-CSF) by ELISA in the CSF and serum of 30 HIV-infected patients classified as AIDS dementia complex (ADC), and 20 subjects with other neurological diseases (OND). We have found a high incidence of detectable IL-6 and GM-CSF in the CSF of ADC patients compared with OND patients. No statistical differences were observed between both groups for serum IL-6 and GM-CSF levels. These results suggest an intrathecal synthesis of these cytokines and a possible involvement in the pathogenesis of ADC.
