Clinical and Biological Characterization of Patients with Low/Intermediate-1 Risk Myelodysplastic Syndrome and Iron Overload

2012

Abstract Abstract 4956 Introduction. Patients with Myelodysplastic Syndrome (MDS) are susceptible to developing iron overload as a response to the red blood cell (RBC) transfusions and ineffective hematopoiesis. This iron overload (IOL) is characterized by an increase in oxygen-reactive species accompanied by a decrease in antioxidants, and results in hepatic, cardiac and endocrine disorders, as well as an increased risk of infection. Ineffective hematopoiesis promotes iron absorption at intestinal level. This process is enhanced by the presence of mutations in the hereditary hemochromatosis gene (HFE). This study aims to define the features that accompany patients with iron overload, compa…
