In recent years, a great number of studies have investigated the possible role of reactive oxygen
species in the aetiology and pathogenesis of rheumatoid arthritis (RA). The aim of this study was to
investigate plasma concentrations of vitamin E, beta-carotene, activities of glutathione peroxidase
(GSH-Px) and catalase, levels of lipid peroxidation (MDA) and reduced glutathione (GSH) in 36
patients with rheumatoid arthritis (RA) and 22 healthy age-matched controls. The plasma activity of
GSH-Px and catalase (p < 0.001), levels of GSH (p < .01), concentration of beta-carotene (p < 0.05)
and vitamin E (p < 0.001), haemoglobin and hematocrit (p < 0.05) were significantly lower in
patients with RA than in controls. The MDA levels (p < 0.01), C reactive protein, rheumatoid factor,
anti-streptolysin-o values (p < 0.001), platelet count (p < 0.05) and erythrocyte sedimentation rate
(p < 0.001) were higher in the patient group than in the control group. These results provide some
evidence for a potential role of increased lipid peroxidation and decreased enzymic and non-enzymic
antioxidants in RA by its inflammatory character. These results suggested that oxidant stress plays
a very important role in the pathogenesis of RA. Copyright 2003 John Wiley & Sons, Ltd.
