Comparative study of DAS-28 ESR and DAS-28 CRP in determining the severity of disease activity in patients with rheumatoid arthritis

Background: Rheumatoid arthritis is a systemic and chronic disease. Combined indicators, such as disease activity score or DAS-28, can be used to categorize quantitative status recovery. But in this calculation there no difference between using ESR CRP. Some studies have showed that CRP instead of will cause the severity underestimated. The aim study was comparison DAS-28 determining patients with rheumatoid arthritis.Methods: This cross-sectional descriptive-analytical on who referred rheumatology clinic Imam Khomeini Hospital. 200 from target community were randomly selected studied. Relevant questionnaires including demographic information age, sex, cigar consumption completed study.Results: In study, RA met inclusion criteria evaluated. results mean age participants 50.38±12.82 those range 18. They up 90 years old 20% people men rest women. alcohol cigarette use 3 cases (1.5%) had history 9 (4.5%) smoking. Examination DAS28 individuals terms lower than less statistically significant (p=0.001). There relationship gender, serum albumin level based VAS DAS28.Conclusions: According present previous studies, it seems if determine disease, better new scoring criterion for patients.
