Iron overload parameters and early detection of cardiac disease among Egyptian children and young adults with β-thalassaemia major and sickle cell disease: a cross-sectional study (original) (raw)
Background: Cardiac, hepatic and pancreatic T2* measured by magnetic resonance imaging (MRI) has been proven to be an accurate and non-invasive method for measuring iron overload in iron overload conditions. There is accumulating evidence that pancreatic iron can predict cardiac iron in young children because the pancreas loads earlier than the heart. The aim of our study was to investigate cardiac function and cardiac iron and their relation to pancreatic iron among patients with β-thalassaemia major (βTM) and sickle cell disease (SCD). Methods: 40 βTM and 20 transfusion-dependant SCD patients were included along with 60 healthy age-matched controls. Echocardiography and Tissue Doppler Imaging were performed for all subjects as well as the control group. Hepatic, cardiac and pancreatic iron overload in cases were assessed by MRI T2*. Results: The study group consisted of 40 βTM and 20 transfusion dependant SCD patients with mean age 13.7 years and mean frequency of transfusion/yea...
