Thalassemia major (TM) is a hereditary blood disease that affects the production of hemoglobin, resulting in severe anemia. Iron overload because of repeated blood transfusion and increased intestinal iron absorption and hemolysis are the major causes of increased oxidative stress in these patients. Growth and maturational delay, cardiomyopathy, endocrinopathies, and osteoporosis are the complications of thalassemia, secondary to anemia and iron overload. The human body has endogenous defense mechanisms to help protect against free radical-induced cell damage. Selenoproteins are important enzymes involved in these antioxidant defense mechanisms. In thalassemia patients, selenoproteins are essential because of their potential defense against oxidative damage due to iron overload and hemolysis. The aim of this review is to provide an overview of data regarding selenoproteins including glutathione peroxidase, thioredoxin reductase and iodothyronine deiodinases in TM patients. We also underline some complications of thalassemia that may be associated with selenoproteins.
