Regular packed cell transfusion in patients with thalassemia major leads to iron overload. Chelation therapy is one of the important aspects of thalassemia care as iron overload causes significant cardiac, hepatic, and endocrine dysfunction. We report a case of thalassemia major with severe iron overload causing cardiac and liver dysfunction who benefitted from triple drug chelation therapy. Tr...

thalassemia is the most prevalent genetic disorder in iran and around the world and these patients need regular careful care. the present study reports results of routine examination of patients visited thalassemia clinic of tehran. data about clinical and laboratory examinations of 413 thalassemic were extracted and analyzed. the prevalence of heart complications, diabetes, growth retardation,...

Background: Thalassemia is a series of hemoglobinopathies in which the production of perfect hemoglobin is completely or partially suppressed. Using injectable iron chelators have been dominating treatment for the iron overload caused by recurrent blood transfusions in thalassemic patients, however, a new oral iron chelating drug (Exjade) have been recently introduced and might be cost effec...

BACKGROUND Plasma non-transferrin bound iron refers to heterogeneous plasma iron species, not bound to transferrin, which appear in conditions of iron overload and ineffective erythropoiesis. The clinical utility of non-transferrin bound iron in predicting complications from iron overload, or response to chelation therapy remains unproven. We undertook carefully timed measurements of non-transf...

Although it is known that Candida albicans causes endothelial cell injury, in vitro and in vivo, the mechanism by which this process occurs remains unknown. Iron is critical for the induction of injury in many types of host cells. Therefore, we investigated the role of iron in Candida-induced endothelial cell injury. We found that pretreatment of endothelial cells with the iron chelators phenan...

Despite receiving no or only occasional blood transfusions, patients with non-transfusion-dependent thalassemia (NTDT) have increased intestinal iron absorption and can accumulate iron to levels comparable with transfusion-dependent patients. This iron accumulation occurs more slowly in NTDT patients compared to transfusion-dependent thalassemia patients, and complications do not arise until la...

Radioiron excretion in the urine and feces after continuous subcutaneous infusion of desferrioxamine (DF) was studied in normal and hypertransfused rats in whom reticuloendothelial and parenchymal iron stores had been labeled by selective 59Fe probes. The existence of two alternative pathways for the chelation of iron in vivo by DF was indicated by the results. The first pathway was intracellul...

SYNOPSIs The differential ferrioxamine test is a simple method for the measurement of chelation of body iron by desferrioxamine. A single six-hour specimen of urine is obtained after intravenous Desferal, accompanied by 59Fe-ferrioxamine. Two values are measured: Fd, the excretion of ferrioxamine derived from body iron by chelation, and Fex, the proportion of ferrioxamine excreted from a known ...
