Role of iron metabolism genetic determinants in response to chelation therapy in a cohort of β-thalassemia and sickle cell syndromes Italian patients
AbstractIn patients with β-thalassemia and sickle cell syndromes there is an important secondary iron overload due to regular blood transfusions and increased duodenal iron absorption. As in genetic hemochromatosis, also the secondary iron storage leads to tissue injury that involves all the major organs: liver, heart, kidney, endocrine glands. At present, in patients with β-thalassemia and sickle cell syndrome, iron chelation therapy is widely used for the treatment of secondary hemochromatosis, to limit the toxic effects of iron overload. In order to maintain the correct homeostasis, several genes are involved in the metabolic pathways of iron, including HFE, FPN (ferroportin) and TF (transferrin). In this study we analyzed the genes HFE, FPN and TF, to assess their possible effects on response to therapy with deferasirox and deferiprone, either as monotherapy or in combination therapy in a cohort of patients with β-thalassemia and sickle cell syndromes.
