n patients with B-thalassemia, regular transfusions are not only essential to maintain acceptable hemoglobin levels for treatment of the underlying anemia but also to suppress endogenous erythropoiesis and pathology due to chronic hemolysis. Unfortunately it inevitably leads to iron overload, such that all patients continuing to receive transfusions in excess of 20 blood transfusions are at progressively increased risk of developing signs or symptoms of iron overload.
