Beta thalassemia major is an inherited disease resulting from reduction or total lack of beta globin chains. Patients with this disease need repeated blood transfusion for survival. This may cause oxidative stress and tissue injury due to iron overload, altered antioxidant enzymes, and other essential trace element levels. The aim of this review is to scrutinize the relationship between oxidative stress and serum trace elements, degree of damage caused by oxidative stress, and the role of antioxidant enzymes in beta thalassemia major patients. The findings indicate that oxidative stress in patients with beta thalassemia major is mainly caused by tissue injury due to over production of free radical by secondary iron overload, alteration in serum trace elements and antioxidant enzymes level. The role of trace elements like selenium, copper, iron, and zinc in beta thalassemia major patients reveals a significant change of these trace elements. Studies published on the status of antioxidant enzymes like catalase, superoxide dismutase, glutathione, and glutathione S-transferase in beta thalassemia patients also showed variable results. The administration of selective antioxidants along with essential trace elements and minerals to reduce the extent of oxidative damage and related complications in beta thalassemia major still need further evaluation.

Background: Cardiac involvement in beta-thalassemia major patients is an important cause of mortality. Therefore, in these patients, timely diagnosis of cardiac disorder is essential. Objectives: The present study aimed at determining the association between cardiac iron overload and fragmented QRS (fQRS). Methods: This cross-sectional study was conducted on 40 β-TM patients, aged 5 - 40 years. The presence of fQRS was evaluated in 12-lead surface electrocardiograms. Cardiac T2* MRI was performed to determine the iron overload. The patients were divided into four groups of chelation therapy. Results: The mean age of patients was reported to be 22.50 ± 6.75 years. The groups showed no significant difference regarding gender, age, or left ventricular ejection fraction. The presence of fQRS was detected in 10 patients (25%), while T2* value was lower than 20 ms in 10 patients (25%). The mean age of patients with and without fQRS was 26.23 ± 2.71 and 19.40 ± 2.61 years, respectively (P = 0.001). The univariate analysis indicated that fQRS had a significant relationship with cardiac iron overload (OR = 5; 95% CI: 1.04 - 23.99; P < 0.044). The multiple logistic regression analysis represented a significant association between iron overload and fQRS (OR = 5.556; 95% CI: 1.027 - 30.049). The sensitivity and specificity of the fQRS against MRI were equal to 50% and 83.3% respectively. Conclusions: The absence of fQRS on ECGs could be a good predictor of the lack of cardiac iron overload in β-TM patients. The results showed that fQRS might indicate the no need for close monitoring for cardiac overload with cardiac MRI and aggressive chelation therapy.
