Objectives: Rheumatoid arthritis (RA) is a progressive, multisystemic disease with a course of chronic inflammation, and which is thought to be immune-originated, though the etiopathogenesis is not fully understood. Elimination of pain with adequate treatment is important in terms of preventing damage and systemic complications. As such, it is important to determine prognostic markers in the evaluation of disease activation. The goal of this study was to explore the relationship between the Disease Activity Score 28 (DAS 28), one of the disease activation indices, erythrocyte sedi- ment rate (ESR) and C-reactive protein (CRP) level.
Methods: A total of 93 patients who presented at the rheumatology polyclinic of Dr. Lütfi Kırdar Kartal Training and Research Hospital were included in the study. Of those, 46 were included in the study group (receiving anti-tumor ne- crosis factor alpha [TNF-α] treatment), and 47 were included in the control group (not receiving anti-TNF-α treatment). The patients enrolled did not have any malignancy or other inflammatory disease. Patients included in the study were also screened for findings of anemia, polycythemia leukocytosis, or lymphocytosis. The DAS 28 score of the study pa- tients was obtained from medical records. Biochemical analyses, as well as CRP and ESR measurements taken after 1 year, were recorded retrospectively.
Results: A statistically significant relationship was observed between the DAS 28 score and ESR in patients who re- ceived anti-TNF-α treatment, while a statistically significant relationship was not found between the DAS 28 score and CRP level. There was no statistically significant relationship in RA patients between the DAS 28 score and ESR or CRP in those who did not receive anti-TNF-α treatment.
Conclusion: According to these results, RA patients receiving anti-TNF- α treatment demonstrated a better ESR marker
of disease activity in long-term follow-up.
