Abstract

Background: Thalassemia patients need repeated transfusion that lead to increased blood ferritin level and iron overload in the heart and liver. Because the roles of hepcidin antimicrobial peptide (HAMP) and hemocromatosis protein (HFE) in iron metabolism have been confirmed, this study investigated the effects of these gene's polymorphisms on blood ferritin levels and iron overload in the heart and liver in patients with beta thalassemia major Materials and Methods: This cross-sectional study was conducted on 91 patients referring to the Hajar Hospital in Shahrekord, Iran in 2015. After the blood samples were collected, the ferritin levels were measured, DNA was extracted from the blood cells, and the types of polymorphisms were determined using PCR-RFLP. Data of MRI T2* in the heart and liver were drawn from the patients' medical files. Data analysis was conducted by t-test, chi-square test, Fisher's exact test, and Pearson correlation coefficient. Results: There was no significant correlation between blood ferritin level and c.-582 A>G polymorphisms of hepcidin gene (p=0.58), and H63D of HFE gene (p=0.818). In addition, there was no significant association between the polymorphisms and heart and liver MRI, but there was a significant association between blood ferritin level and qualitative heart and liver MRI (r=-0.34, p=0.035 and r=-0.001, p=0.609, respectively). Conclusion: In patients with β-thalassemia major, the presence of c.-582A>G HAMP and H63D HFE polymorphisms is not effective on blood ferritin level and iron overload in the heart and liver in the studied region.
