Hepcidin is Linked to Hypoferremia in Patients With Rheumatic Valve Disease

Abstract

Background and Aim: Hepcidin has been shown to be an acute phase reactant, induced by infection and inflammation. Ongoing inflammation was shown in rheumatic valve disease (RVD). In this study we want to investigate whether there is a relationship between inflammation and impaired iron metabolism and the role of hepcidin on serum iron levels. Methods and Results: Fourty-six patients with RVD and 34 healthy individuals were included in the study. Serum hepcidin, high-sensitive C-reactive protein (hs-CRP), hemoglobin, hematocrit, iron, iron-binding capacity, ferritin levels were measured. Serum hepcidin levels were significantly increased in patients with RVD than in control group (316 ± 121 ng/mL vs 435 ± 126 ng/mL; P < .001). Serum hs-CRP levels were no significantly higher in the patient group in than in the control group (3.9 ± 3.6 mg/L vs 3.5 ± 3.7 mg/L; P = .521). Conclusion: Hepcidin levels are decreased independently from hs-CRP levels as a compensatory mechanism to increase the iron absorption in response to decreased serum iron levels in patients with RVD.
