Abstrakt: Background: Rheumatoid arthritis (RA) is a chronic systemic autoimmune inflammatory disorder characterized by synovial inflammation that leads to joint damage, bony erosions, and related deformities. Between 30 and 70% of RA patients will experience anemia. Early detection of anemia is of great importance. This study aimed to evaluate the serum level of hepcidin (HEP) in RA patients and to assess its relation to disease activity and anemia. The current cross-sectional study included 44 cases with RA in addition to 44 healthy controls. The disease activity in the RA patient was assessed by using the disease activity score (DAS) 28 score-CRP. The serum levels of HEP and ferritin were assessed in both groups using enzyme-linked immunosorbent assay (ELISA) technique. Results: Hepcidin level in the RA group was statistically significantly higher as compared to the control group (p = 0.001). The prevalence of Anemia of chronic disease (ACD) was 40.9%, and iron deficiency anemia (IDA) was 27.3% which accounted for 68.2% of the total anemia cases. The HEP level was statistically significantly higher in the RA patients with ACD than those without anemia (P = 0.028), RA patients with IDA (P < 0.001), and control group (P < 0.001). There was a statistically significant positive correlation between HEP level and serum ferritin level (p = 0.005). HEP level was significantly and inversely correlated with hemoglobin (Hb) in patients with ACD. Serum HEP level is higher in RA patients with high disease activity than those with moderate activity, low activity, and patients in remission (p = 0.380). However, the difference was not statistically significant. The best cutoff point of HEP level to identify RA patients from healthy controls was > 355.5 Pg/ml. This point showed moderate sensitivity (70.5%) with moderate specificity (63.6%) with a statistically significant value. Conclusions: We found the anemia, and particularly ACD, is more common in RA patients. In RA patients with ACD, serum HEP levels were considerably higher. Although serum HEP showed no diagnostic significance when it came to evaluating disease activity, it could be a dependable non-invasive biomarker for the diagnosis of various forms of anemia in RA patients.
