[Assay of erythrocyte, platelet and serum superoxide dismutase, glutathione peroxidase and catalase in rheumatoid polyarthritis].

The authors present a study of superoxide dismutase, catalase and glutathione peroxidase in hemolysis product, platelets and serum of 23 patients with rheumatoid polyarthritis and 11 healthy subjects. The nature of the treatment enables to divide the 23 patients into 3 groups: group I (8 cases): no treatment; Group II (7 cases): steroid therapy alone; group III (8 cases): basic treatment associated (3 cases) or not (5 cases) to steroid therapy. Statistical analysis shows no significant difference, whatever the environment and the treatment contemplated. The significance of these results is discussed and compared with literature data concerning only enzymatic activities and not the blood levels as in the present study.
