Comparison of effects of oral deferiprone and subcutaneous desferrioxamine on myocardial iron concentrations and ventricular function in beta-thalassaemia.
BACKGROUND Despite the introduction of the parenteral iron chelator desferrioxamine more than 30 years ago, 50% of patients with thalassaemia major die before the age of 35 years, predominantly from iron-induced heart failure. The only alternative treatment is oral deferiprone, but its long-term efficacy on myocardial iron concentrations is unknown. METHODS We compared myocardial iron content...
متن کاملLogarithmic quantitation model using serum ferritin to estimate iron overload in secondary haemochromatosis.
Nineteen children and adolescents receiving repeated transfusions and subcutaneous desferrioxamine treatment were investigated in an attempt to quantitate iron overload non-invasively. Before patients were started on desferrioxamine individual relationships were correlated for 12 to 36 months between transfused iron, absorbed iron estimated gastrointestinally, and increasing serum ferritin conc...
متن کاملReversal of haemochromatotic cardiomyopathy in beta thalassaemia by chelation therapy.
Haemochromatotic cardiomyopathy is the main cause of morbidity and mortality in patients with beta thalassaemia major. Once congestive heart failure develops most patients die in a few months. Congestive heart failure was reversed and echocardiographic findings were restored to normal in a 24 year old woman with beta thalassaemia who resumed treatment with chelation therapy (desferrioxamine).
متن کاملEarly iron overload in beta-thalassaemia major: when to start chelation therapy?
Twenty-eight children with beta-thalassaemia major aged between 11 and 48 months were given intensive transfusions. Serum iron, transferrin saturation, serum ferritin, non-transferrin iron, and subcutaneous desferrioxamine-induced urinary iron excretion were measured. The results showed that even children with a limited number of transfusions had severe iron overload as indicated, in particular...
متن کاملOcular changes in patients undergoing long-term desferrioxamine treatment.
In a group of young patients with thalassaemia and iron overload treated by subcutaneous infusions of desferrioxamine we have found a number of minor alterations in retinal function. The incidence of such changes is not related to drug dosage or to ferritin level but to abnormality of the extended glucose tolerance test.
