Evidence for oxidative stress in osteoarthritis
Journal Title: Indian Journal of Clinical Biochemistry - Year 2005, Vol 20, Issue 2
Abstract
Evidence of increased oxidative stress in patients of osteoarthritis in comparison with healthy control subjects was investigated by measuring the thiobarbituric acid reactive substances (TBARS), vitamin C, reduced glutathione (GSH) and the activities of superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx) in erythrocytes. It was observed that osteoarthritis patients were more susceptible to oxidative damage than controls as evident from increased TBARS and decreased ascorbic acid, GSH, catalase and GPx in erythrocytes. Significant increase in SOD activity found in patients might be an adaptive response. With the understanding of the role of antioxidants in arthritis, it is becoming increasingly clear that these agents seem to be beneficial in osteoarthritis.
