Deferasirox: pharmacokinetics and clinical experience
No full textIntroduction: Iron overload is an inevitable consequence of transfusion therapy for a variety of underlying anemias. Iron overload, without effective chelation, will lead to significant morbidity and mortality. Deferasirox (Exjade®) is an oral tridentate iron chelator used for reducing iron overload. Areas covered: In addition to the pharmacokinetic and pharmacodynamic profile of deferasirox, this review examines the efficacy and safety data from pivotal studies with deferasirox in iron-overloaded patients with various anemias, including thalassemia, sickle cell disease and myelodysplastic syndromes. A qualitative literature search for deferasirox was performed using PubMed and recent key congress publications (EHA and ASH); key search terms were deferasirox, pharmacokinetic, pharmacodynamic, efficacy and safety. Expert opinion: Based on the current available data, deferasirox treatment is effective with a clinically manageable safety profile although appropriate dosing according to the severity of iron burden and iron intake, together with the careful monitoring of laboratory parameters and adverse events, is recommended. However, despite advances made in the treatment of iron overload, some patients still do not respond adequately to iron chelators, and increased awareness, understanding and further research are still needed

Responsiveness to oral iron and ascorbic acid in a patient with IRIDA
No full textMutations in TMPRSS6 gene cause iron-refractory iron deficiency anemia, a rare autosomal recessive disorder characterized by hypochromic microcytic anemia not responsive to oral iron therapy and partially responsive to parenteral iron administration. Here we report a female infant homozygous for a loss of function mutation in TMPRSS6 gene, who responded to oral iron therapy when supplemented with ascorbic acid
