Improving survival with deferiprone treatment in patients with thalassemia major: A prospective multicenter randomised clinical trial under the auspi…

2009

The prognosis for thalassemia major has dramatically improved in the last two decades. However, many transfusion-dependent patients continue to develop progressive accumulation of iron. This can lead to tissue damage and eventually death, particularly from cardiac disease. Previous studies that investigated iron chelation treatments, including retrospective and prospective non-randomised clinical trials, suggested that mortality, due mainly to cardiac damage, was reduced or completely absent in patients treated with deferiprone (DFP) alone or a combined deferiprone-deferoxamine (DFP-DFO) chelation treatment. However, no survival analysis has been reported for a long-term randomised control …

Long-term sequential deferiprone-deferoxamine versus deferiprone alone for thalassemia major patients: a randomised clinical trial

2009

A multicentre randomized open-label trial was designed to assess the effectiveness of long-term sequential deferiprone–deferoxamine (DFO–DFP) versus DFP alone to treat thalassaemia major (TM). DFP at 75 mg/kg, divided into three oral daily doses, for 4 d/week and DFO by subcutaneous infusion (8–12 h) at 50 mg/kg per day for the remaining 3 d/week was compared with DFP alone at 75 mg/kg, administered 7 d/week during a 5-year follow-up. The main outcome measures were differences between multiple observations of serum ferritin concentrations. Secondary outcomes were survival analysis, adverse events, and costs. Consecutive thalassaemia patients (275) were assessed for eligibility; 213 of these…

Sequential alternating deferiprone and deferoxamine treatment compared to deferiprone monotherapy: main findings and clinical follow-up of a large mu…

2011

In β-thalassemia major (β-TM) patients, iron chelation therapy is mandatory to reduce iron overload secondary to transfusions. Recommended first line treatment is deferoxamine (DFO) from the age of 2 and second line treatment after the age of 6 is deferiprone (L1). A multicenter randomized open-label trial was designed to assess the effectiveness of long-term alternating sequential L1-DFO versus L1 alone iron chelation therapy in β-TM patients. Deferiprone 75 mg/kg 4 days/week and DFO 50 mg/kg/day for 3 days/week was compared with L1 alone 75 mg/kg 7 days/week during 5-year follow-up. A total of 213 thalassemia patients were randomized and underwent intention-to-treat analysis. Statisticall…

Potential Myocardial Iron Content Evaluation by Magnetic Resonance Imaging in Thalassemia Major Patients Treated with Deferoxamine or Deferiprone Dur…

2003

The purpose of this study was to evaluate if the variations of heart magnetic resonance imaging in beta-thalassemia major patients treated with Deferoxamine B mesylate (DF) or Deferiprone (L1) chelation therapy is a useful tool of the indirect myocardial iron content determination. For this reason, a prospective study was carried out. Seventy-two consecutive patients with beta-thalassemia major (35 treated with DF and 37 with L1) were studied. The main outcome results were laboratory parameters including determination of the liver iron concentration (LIC) and magnetic resonance imaging (MRI) of the heart and liver. The heart to muscle signal intensity ratios (HSIRs) were significantly incre…

Deferiprone versus deferoxamine in patients with thalassemia major: a randomized clinical trial.

2002

Deferiprone has been suggested as an effective oral chelation therapy for thalassemia major. To assess its clinical efficacy, we compared deferiprone with deferoxamine in a large multicenter randomized clinical trial. One-hundred forty-four consecutive patients with thalassemia major and serum ferritin between 1500 and 3000 ng/ml were randomly assigned to deferiprone (75 mg/kg/day) (n = 71) or deferoxamine (50 mg/kg/day) (n = 73) for 1 year. The main measure of efficacy was the reduction of serum ferritin. Liver and heart iron contents were assessed by magnetic resonance. Liver iron content and fibrosis stage variations were assessed on liver biopsy by the Ishak score in all patients willin…
