title: Investigation of cytokine (tumor necrosis factor-alpha, interleukin-6, interleukin-10) concentrations in the cerebrospinal fluid of female patients with multiple sclerosis and systemic lupus erythematosus.
abstract: Humoral immune response seems to play a role in the pathogenesis of multiple sclerosis (MS) and in the central nervous system (CNS) complications of systemic lupus erythematosus (SLE). The aim of the present study was to compare the levels of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and IL-10 in the cerebrospinal fluid of female patients with several forms of MS (50 patients), and in female patients with several types of CNS complications in SLE (50 patients). Samples were investigated using an enzyme-linked immunosorbent assay technique. Involvement of CNS in SLE patients seems to be characterized with elevated concentrations of all three cytokines in CNS and intrathecal synthesis of IL-6. In MS patients, an intrathecal synthesis of TNF-alpha (relapsing-remitting form) and IL-6 (primary progressive form) were observed. Clinical forms of MS seem to be immunologically heterogeneous. The activation of cytokine network was observed in SLE patients with CNS complications, independent of the pathological process. Similarities between SLE and MS patients with the primary progressive form of the disease were demonstrated concerning the intrathecal synthesis of IL-6. Only MS patients with the relapsing-remitting clinical form showed intrathecal TNF-alpha synthesis.
