Brief Summary

Beta-thalassemia represents a group of recessive inherited hemoglobin disorders characterized by reduced synthesis of β-globin chain. The homozygous state (β-thalassemia major) "TM" results in severe anemia, which needs regular blood transfusion . The life expectancy in patients with TM has increased due to therapeutically management, such as frequent transfusion, desferal administration and bone marrow transplantation. Diabetes is clinically characterized by hyperglycemia due to either low circulating concentrations of, or decreased sensitivity to, insulin. Patients with TM typically exhibit β-cell or insulin insufficiency, and may develop diabetes due to toxic levels of iron in their pancreas, one of the strongest predictors of β-cell destruction. By contrast, hyperinsulinemia, secondary to insulin resistance, with normal glucose tolerance has also been observed. The pathogenic mechanisms leading from siderosis to diabetes are poorly understood.
