Brief Title: Comparing CGM and OGTT in Relation to Iron Overload Detected by Pancreas T2* MRI in High-Risk Hematology Group
Official Title: Continuous Glucose Monitoring (CGM) Versus Oral Glucose Tolerance Test (OGTT) Versus T2* MRI Of The Pancreas In High-Risk Group (Hemoglobinopathies, Lymphoma & Acute Lymphoblastic Leukemia): A Comparative Study
Study ID: NCT03141398
Brief Summary: A prospective, observational, comparative study with no intervention.The objective of the study to compare the efficiency of detecting glycemic abnormalities using Continuous Glucose Monitoring (CGMs) versus Oral Glucose Tolerance Test (OGTT) and HbA1C (Glycated Hemoglobin) and their relation to iron overload detected by T2\* MRI of the pancreas in high-risk patients due to insulin deficiency (potential beta cell injury) and those with insulin resistance and to study the different factors that may affect the glycemic control in these patients in relation to their results like the Dose of corticosteroids and chemotherapy in ALL and Hemoglobinopathies, Liver function in ALL and Hemoglobinopathies, and Serum ferritin in Hemoglobinopathies and their transfusion status. Using Validated Tools with Permission, the participants will be selected through probability (random) sampling method with expected subjects numbers ALL/L: 30-50, Thalassemia Major: 20, Sickle cell disease: 20.
