Abstract:
Two Chinese patients with hemoglobin (Hb) H disease without a history of blood transfusion developed iron overload at the age of 45 and 53 years, respectively. Human leukocyte antigen (HLA) system types of these 2 patients were A19, A11, B13, B62 and A2, A24, BW55, respectively, which are not related to the common haplotypes for idiopathic hemochromatosis. Since severe iron loading is a rare clinical manifestation in untransfused patients with Hb H disease, the iron overload in both patients may be due to environmental or underlying genetic factors.
