Desferrioxamine (DFX) alone (40-50 mg/kg/d s.c. over 8-12 h, five times weekly) was compared with combined DFX twice weekly and deferiprone (75 mg/kg/d) over 12 months in previously poorly chelated thalassaemia patients. Serum ferritin fell from 5506 ± 635 μg/1 (mean ± SEM) to 3998 ± 604 μg/1 (P < 0.001; n = 14) in the DFX group and from 4153 ± 517 μg/1 to 2805 ± 327 μg/1 in the combined group (P < 0.01; n = 11). Deferiprone plus DFX produced a greater mean urine iron excretion (1.01 mg/kg/24 h) than iron intake from blood transfusion in each patient. Main side-effects were skin reactions (DFX alone), nausea and arthralgia (combined therapy). As chelation therapy, the combined protocol was as effective as DFX five times weekly.
