Abstract
Zinc is one of the essential micronutrients in human and act as a cofactor for more than 300 enzymes and plays an essential role in human growth and development. It has been observed that there was low serum zinc and elevated copper level in β-thalassemia major compared with normal. Zinc deficiency is considered one of the main factors contributing to growth, cardiovascular diseases, and puberty disorders in β-thalassemic patients. Aim: The goal of the study was to scrutinize the impact of serum zinc and copper concentration in patients with beta-thalassemia major and also to observe the effect of zinc supplementation on transfusion dependent beta-thalassemia patients for six months. Method: 52 beta-thalassemia major patients were studied before and after supplementation of zinc for six months, and status was compared with 52 age and sex-matched healthy normal. Serum zinc and copper concentration were measured by atomic absorption spectrophotometry (AAS) method. Result: There was a significant depleted activity of serum zinc level (p<0.001), and the copper level was increased significantly (p<0.001) in patients when compared with normal. After six months of supplementation of zinc, there was a significantly enhanced zinc concentration (p<0.001),and copper was marginally increased (p>0.05) when compared with normal and baselines. Conclusion: Beta Thalassemia major children are on numerous blood transfusions all the way through their life. Due to this thalassemic children are at risk of secondary iron burden. This further leads to the enhanced oxidative stress. One of the way to may overcome this situation to supply regular zinc supplementation along with treatment, which may be helpful to manage the situation.
