Deferiprone in the treatment of transfusion-dependent thalassemia: a review and perspective
نویسنده
چکیده
Deferiprone is an orally active iron chelator which has emerged from an extensive search for new treatment of iron overload. Comparative studies have shown that at comparable doses deferiprone may be as effective as deferoxamine in removing body iron. Retrospective and prospective studies have shown that deferiprone monotherapy is significantly more effective than deferoxamine in improving myocardial siderosis in thalassemia major. Agranulocytosis is the most serious side effect associated with the use of deferiprone, occurring in about 1% of the patients. More common but less serious side effects are gastrointestinal symptoms, arthralgia, zinc deficiency, and fluctuating transaminases levels. Deferiprone can be used in combination with desferrioxamine. This regimen of chelation is tolerable and attractive for patients unable to comply with standard deferoxamine infusions or with inadequate response to deferiprone alone. Combination therapy has been effectively used in the management of severe cardiac siderosis.

Abstract Thalassemia syndromes are the most common inherited hemoglobinopathies in the world characterized by various degrees of defective production of the alpha or beta globin chains. Impairment in alpha chain or beta chain synthesis leads to alpha thalassemia and beta thalassemia syndromes respectively.

متن کاملRelationship between serum ferritin and growth status of pediatric transfusion dependent thalassemia
Background: Growth retardation is a long-term complication in pediatric transfusion-dependent thalassemias (TDTs), presented as short-stature and upper body segment shortening. The cause of this condition was chronic hypoxia, iron overload, endocrinopathy, inadequate transfusion, and iron chelation. We analyze the relationship between ferritin level and growth status of pediatric TDTs. Methods...

Background: Iron extra load is an anticipated and lethal consequence of chronic blood transfusion in major beta-thalassemia patients; therefore it is necessary to use an efficient iron chelator drug to stimulate the evacuation of the surplus iron from the body. This trial was performed to compare myocardial and hepatic magnetic resonance imaging T2 (MRI T2*) results of beta-thalassemia patients...

Transfusional iron overload is a major target in the care of patients with transfusion-dependent thalassemia (TDT) and other refractory anemias. Iron accumulates in the liver, heart, and endocrine organs leading to a wide array of complications. In this review, we summarize the characteristics of the approved iron chelators, deferoxamine, deferiprone, and deferasirox, and the evidence behind th...

Regular blood transfusion along with iron chelation therapy is a supportive treatment for thalassemia major. Chelation therapy too has its side effects. The most common adverse effects associated with administration of deferiprone are agranulocytosis, neutropenia and arthralgia, primarily, of the large joints. Objective : The study was undertaken to examine the effect of deferiprone on the larg...
