Iron acquisition is essential for the growth of Mycobacterium tuberculosis. Hepcidin is known as an antimicrobial peptide and a component of the innate immune response. Hepcidin inhibits M. tuberculosis growth in vitro. In this study, we decided to identify -582A> G variants of the HAMP promoter in patients with tuberculosis (TB) and investigate its effect on serum iron, ferritin, and hepcidin levels.The sample population consisted of 105 patients with TB and 104 healthy individuals. The -582A> G polymorphism was genotyped using a tetra-primers PCR set. Serum levels of hepcidin were determined using an ELISA kit. Statistical analysis was performed using SPSS software.The G allele is meaningfully associated with TB disease (95% confidence interval = 2-4.8, p G polymorphism genotypes. There was significant reverse correlation between hepcidin and iron (r = -0.849, p = 0.006).A high association was found between serum hepcidin levels and the HAMP -582A> G variants in patients with TB. These observations indicate a hypothetical role of this polymorphism in iron metabolism. Hepcidin could perhaps be an option for the treatment of TB.
