The Effect of Alpha-tocopherol in Hemolysis and Oxidative Stress Marker on the Red Cell Membrane Beta-thalassemia Major

Summary

The accumulation of unpaired α-globin chains in β-thalassemia major patients may clinically create ineffective erythropoiesis, hemolysis, and chronic anemia. Multiple blood transfusions and iron overload cause cellular oxidative damage. However, α-tocopherol, an antioxidant, has been known as a potent scavenger of lipid radicals in the red cell membrane of β-thalassemia major patient. By this randomized controlled trial, the investigators would like to evaluate the effects of α-tocopherol in hemolysis and oxidative stress on the red cell membrane of β-thalassemia major.
