Abstract

Introduction and Aim: Beta Thalassemia trait (BTT) is the most prevalent heterozygous hemoglobinopathy in Asian population. The current study aims to evaluate plasma antioxidant metalloproteins like SOD, ceruloplasmin, ferritin and correlate them with the trace elements in patients with BTT. Materials and Methods: The subjects included in the study were divided into two groups comprising of 40 BTT patients in group I and 40 age and sex matched normal individuals in group II. Cation exchange HPLC was used for hemoglobin variant analysis. Plasma iron, copper, ceruloplasmin and SOD were assayed using the spectrophotometric method while zinc was determined by atomic absorption spectrometry and ferritin by ECLIA. Results: There was a marked reduction in plasma trace elements in BTT compared to healthy controls. The decrease in zinc (p<0.001) and copper (p<0.04) was statistically significant. Both SOD and ferritin levels were significantly lower in BTT patients (p<0.001). However, an apparent decrease was observed in ceruloplasmin levels. Iron and ferritin showed a significant positive correlation (r=0.84 p=0.01), similarly copper and ceruloplasmin correlated positively (r=0.92 p=0.001) in BTT patients. Interestingly HbF correlated negatively with all the three trace elements. Conclusion: It can be concluded that decreased antioxidant metalloproteins may lead to free radical toxicity in BTT. The study highlights the indirect role of trace elements in oxidative stress and draws attention on the requirement for regular and timely assessment of metalloenzymes and periodic administration of trace elements in reduction of free radical damage and associated complications in BTT patients.
