Deferiprone (L1) has been recommended as an effective oral chelation therapy for patients with ß-thalassemia major (TM). From 1999 to 2004, 114 patients with TM from five treatment centers were enrolled in this program: iron (Fe) was chelated with L1 in 57 patients, deferoxamine (DFO) in 26, and combined L1/DFO therapy in 31. We found that serum ferritin (SF) was significantly lower in nine patients receiving L1 for more than 5 years ( p = 0.04), 22 patients receiving L1 for 1–2 years ( p [ABSTRACT FROM AUTHOR]

Deferiprone (L1) has been recommended as an effective oral chelation therapy for patients with beta-thalassemia major (TM). From 1999 to 2004, 114 patients with TM from five treatment centers were enrolled in this program: iron (Fe) was chelated with L1 in 57 patients, deferoxamine (DFO) in 26, and combined L1/DFO therapy in 31. We found that serum ferritin (SF) was significantly lower in nine patients receiving L1 for more than 5 years (p = 0.04), 22 patients receiving L1 for 1-2 years (p < 0.01) and 31 receiving the combined therapy (p = 0.01), yet significantly higher in those receiving DFO only (p < 0.01). One patient showed transient neutropenia; arthropathy in one patient and gastrointestinal upset in two were noted, with no significant change in alanine aminotransferase (ALT) level. Of 17 patients who were submitted to a liver biopsy, 15 showed no significant change in hepatic fibrosis scores after therapy with L1. None of the 88 patients, including 31 who received the combined therapy, have abandoned oral L1 treatment due to adverse effects. Results of this study proved that L1 or combined therapy with L1 and DFO is effective in reducing SP; incidence of adverse events was low in patients with TM.
