Most deaths in thalassemia major (TM) result from cardiac complications due to iron overload. No data are available in literature about possible different changes in cardiac iron in TM patients treated with sequential deferipron-deferoxamine (DFP-DFO) versus deferipron (DFP) and deferoxamine (DFO) in monotherapy. Magnetic Resonance (MR) is the unique non invasive suitable technique to evaluate quantitatively this issue. Our aim was to prospectively assess in the clinical practice the efficacy of the DFP-DFO versus DFP and DFO in monotherapy in a cohort of TM patients by quantitative MR.
Among the first 739 TM patients enrolled in the MIOT (Myocardial Iron Overload in Thalassemia) network, 253 patients performed a MR follow up study at 18 ± 3 months according to the protocol. We evaluated prospectively the 25 patients treated with DFP-DFO versus the 30 patients treated with DFP and the 66 patients treated with DFO between the 2 MR scans. Myocardial iron concentrations were measured by T2* multislice multiecho technique.
Prospectively in a clinical setting over 15 months we did not find significant differences on cardiac iron in TM patients treated with sequential DFP-DFO versus the TM patients treated with DFO. Conversely, DFP monotherapy was significantly more effective than DFP-DFO in improving myocardial siderosis.
