Popis: | Introduction: The purpose of our study was to evaluate the effectiveness and safety of combined therapy with deferoxamine (DFO) and deferiprone (DFP) in patients with b-thalassemia major and increased serum ferritin. Patients and methods: Our study was performed in 36 patients with b-thalassemia major. DFP was administered orally in a total daily dose of 60 mg/kg for 6 days per week and DFO was administered subcutaneously in a total daily dose of 40–50 mg/kg for 4–6 days per week. The efficacy of combined treatment was assessed by measurements of serum ferritin and 24-h urine iron excretion levels. Results: Out of the 36 patients, 11 discontinued DFO after a mean of 4 months; however, 25 patients, who continued to receive the combined therapy showed a very satisfactory compliance. After a mean of 13.5 months, their mean serum ferritin levels reduced from 263771292 to 158071024 ng/ml (P ¼ 0.002) and their mean urinary iron excretion elevated from 0.4170.27 to 0.7670.49 mg/24 h (P ¼ 0.003). The observed side effects were gastrointestinal disorders, elevations in liver enzymes, mild neutropenia, joint symptoms, taste disorders, dizziness and fatigue. Conclusions: The results of this study show that combined iron-chelation therapy with DFO and DFP results in satisfactory reduction of serum ferritin with no significant toxicity.
