Background: Rheumatoid arthritis (RA) is commonly associated with abnormalities in plasma lipoprotein levels, especially a significantly low level of high density lipoprotein (HDL). Most treatments for RA, particularly biological drugs, decrease atherogenic index. Improvement in lipoprotein profile has been found to be associated with decrease in inflammation in RA patients. This study was designed to survey the relationship between lipid profile and RA activity index.Methods: This cross-sectional study included a total of 200 randomly selected RA patients. After blood sampling, plasma levels of triglyceride (TG), cholesterol, low density lipoprotein (LDL), HDL were measured. The correlations between these indices and disease activity index were then evaluated using disease activity score calculator (DAS28). The collected data was statistically analyzed by SPSS18. Pierson and Spearman correlation coefficients were applied for data analysis. Multiple regression test and factorial model were used to control bias..Findings: Examination of the relation between LDL levels and RA criteria revealed a direct significant association of 0.13. A significant association of 0.17 was also found between pain intensity (based on visual analogue scale) and LDL levels. Moreover, LDL and tender joints were significantly associated (0.16). There were no statistically significant associations between LDL, joint swelling and erythrocyte sedimentation rate (ESR). HDL levels did not show significant relations with ESR, pain intensity and tender joints (P > 0.05). However, there was a significant reverse association between HDL levels and joint swelling (0.16).Conclusion: This study showed that lipid profile and RA were significantly related in many aspects. This finding was in accordance with the results of other similar studies. Therefore, it seems advisable to check the lipid profile of patients with chronic inflammatory diseases, especially RA, on a regular basis.
