title: [Neopterin: new immunological marker of autoimmune rheumatic disease].
abstract: Serum neopterin (SN), concentration of soluble (s) TNF-receptors (R) with molecular mass 55 kD and sIL-2R, C-reactive protein (CRP), Willebrand factor antigen (WF Ag) were measured in enzyme immunoassay (EIA) or radioimmunoassay (BRAHMS, Berlin, Germany) in 189 patients with autoimmune rheumatic diseases: 52 patients with systemic lupus erythematosus (SLE), 67 patients with rheumatoid arthritis (RA), 44 patients with polymyositis/dermatomyositis and 26 patients with Wegener granulomatosis. SN appeared elevated in autoimmune rheumatic diseases correlating with the disease activity and concentrations of sTNF R and sIL 2R. Assay for neopterin is clinically essential for examination of the immunopathological process activity, prediction of the outcomes, better knowledge about cytokine synthesis profile in autoimmune rheumatic diseases.
