Evaluation of the level of C-reactive protein and associated risk factors in RA patients was the main aim of this study. Identifying the association between disease activity of RA (hsCRP) and socio-demographic characteristics was another aim of the study.Methods: Institution-based cross-sectional study was conducted at the Rheumatology Clinic of Tikur Anbessa Specialized Hospital. In this study, the level of hsCRP was measured in both case and control groups. Simple descriptive statistics, multivariate analysis, independent sample t-test were utilized for statistical analysis. The strength of association between different risk factors and hsCRP was measured using odds ratio and 95% confidence interval. P-value < 0.05 was considered as statistically significant.Result: The result of this study showed that the hsCRP level was significantly higher among RA patients as compared to the control groups (P-value = 0.004). There was an association between smoking and high disease activity status (AOR= 20.03, p= 0.40). Low economic status had a statistically significant association with high hsCRP level (AOR = 12.79, p=0.00). In this study, 42 RA patients had > 3mg/l hsCRP level with different occupational exposures. On the other hand, 31 RA patients had < 3mg/l hsCRP level among different exposures. Although there was no statistically significant association, the association between associated risk factors (oil consumption, physical exercise, educational status) and disease activity was computed in this study.Conclusion: The inflammatory marker, hsCRP was significantly higher among patients as compared to controls. The higher hsCRP showed a high grade of systemic inflammation in RA patients. C-reactive protein was elevated in rheumatoid factor positive patients and patients with high BMI value. Additionally, the result of our study showed that different socio-economic factors had an association with disease activity of RA.Keywords: rheumatoid arthritis, disease activity, C-reactive protein |
