Abstract

To evaluate the iron metabolism and oxidative status in patients with Hb H disease, we investigated 43 patients with Hb H disease, including eight deletional Hb H disease patients and 35 nondeletional Hb H disease patients and 20 healthy controls. The levels of hematological parameters, serum ferritin, hepcidin, superoxide dismutase (SOD), malondialdehyde (MDA) and total antioxidant capacity (TAC), were examined. We found higher serum ferritin levels and lower hepcidin, MDA and TAC levels in Hb H disease patients than in controls. The hepcidin level in Hb H disease patients was positively correlated with MDA and TAC levels but not with serum ferritin and SOD levels. The patients with nondeletional Hb H disease showed higher serum ferritin and Hb H concentrations than those patients with deletional Hb H disease. However, no statistically significant differences in SOD, MDA and TAC levels were found in patients with deletional and nondeletional Hb H disease. Oxidative stress and antioxidant defense were related to hepcidin levels. Our study indicated that hepcidin might be an important parameter for monitoring the iron metabolism and oxidative status of Hb H disease patients.
