Serum lipids and lipoprotein concentrations in women with rheumatoid arthritis

Serum lipid and lipoprotein concentrations were measured in 51 women with rheumatoid arthritis treated with both nonsteroidal and steroidal drugs and compared to a group of women with rheumatoid arthritis not receiving anti-inflammatory drugs and to a healthy control group. Significantly lower concentrations of total cholesterol and low density lipoprotein cholesterol were found in the rheumatoid patients on nonsteroidal or steroidal anti-inflammatory drugs, while no difference was found in high density lipoprotein cholesterol and triglycerides. In the group of rheumatoid patients who received no nonsteroidal or steroidal anti-inflammatory drugs, the triglyceride level was higher than in the control group, and that of HDL-C was lower. Total cholesterol and LDL-C levels were higher in the patients not on anti-inflammatory drugs than in patients receiving anti-inflammatory drugs. The results of this study suggest that hyperlipidemia is not one of the predisposing factors for coronary disease in patients with rheumatoid arthritis receiving anti-inflammatory therapy. Anti-inflammatory drugs may play a role in the regulation of serum lipids in patients with rheumatoid arthritis.
