Abstract
The present study has investigated the levels of lipids, lipoprotein cholesterol (HDL and LDL cholesterol), thiobarbituric acid reactive substances (TBARS) and vitamin E in plasma and erythrocyte membranes of twenty two clinically diagnosed adult rheumatoid arthritis patients and an equal number of age matched healthy subjects. The levels of lipids and lipoprotein cholesterol were markedly reduced in patients with rheumatoid arthritis as compared to healthy subjects. The altered lipid pattern may be related to decreased lipoprotein cholesterol, fatty acids and impairment in antioxidant defence mechanism.
