Myocardial iron overload is the leading cause of death in patients with β-thalassemia major. An intensification monotherapy with deferoxamine (DFO) as well as a combination therapy with DFO and deferiprone (DFP) reduces myocardial iron and improves cardiac function. However, the prognosis for thalassemia major patients with established cardiac disease switched from DFO monotherapy to combined DFP/DFO chelation is unknown. Twenty-eight thalassemia major patients with cardiac disease were enrolled in a prospective study lasting 42 ± 6 months. Fifteen (9 high-ferritin and 6 low-ferritin) were placed on DFP/DFO (DFP, 75 mg/kg t.i.d.; DFO, 40–50 mg/kg over 8–12 h at night 5–7 days/week), while 13 (5 high- and 8 low-ferritin) received DFO alone. No cardiac events were observed among high-ferritin patients on combination therapy, whereas 4 cardiac events (p = 0.0049), including three deaths, occurred in high-ferritin patients on DFO monotherapy. These findings demonstrate that in thalassemia major patients with well-established cardiac disease combined iron-chelation therapy with DFP/DFO is superior to DFO monotherapy.
