Title

EFFECTS OF VITAMIN E AND ZINC SUPPLEMENTATION ON ANTIOXIDANTS IN BETA THALASSEMIA MAJOR PATIENTS

Pages

  8-14

Abstract

 Objective: In beta thalassemic patients, tissue damage occurs due to oxidative stress and it happens because of the accumulation of iron in the body. This study was conducted to determine the effect of ZINC and VITAMIN E supplementation on antioxidant status in beta-thalassemic major patients.Methods: This double blind randomized clinical trial was carried out on 120 beta thalassemic patients older than 18 years. Patients were randomly categorized in four groups. ZINC (50mg/day) and VITAMIN E (400mg/day) supplements were administered for former and latter group, respectively. In the third group both supplements were administered in similar doses. The fourth (control) group received no supplement. The effect of supplementations on serum ZINC and VITAMIN E, SUPEROXIDE DISMUTASE (SOD), GLUTATHIONE PEROXIDASE (GPX), total antioxidant capacity (TAC) and BODY MASS INDEX (BMI) were measured at the beginning and the end of the study.Findings: Serum ZINC levels in group 1 and 3 were significantly increased (P<0.007 and P<0.005, respectively). Serum VITAMIN E levels in group 2 and 3 were also increased significantly (P<0.001).Mean GPX activity in group1, 2 and 3 decreased significantly (P<0.015, P<0.032 and P<0.029, respectively). Mean SOD activity and TAC did not show significant change after supplementation.BMI had significant increase in all treated groups (P<0.001).Conclusion: Our results suggest that beta thalassemic patients have enhanced oxidative stress and administration of selective ANTIOXIDANTS may preclude oxidative damage.
