It has been anticipated that iron and ferritin burden in patients with beta thalassemia major is associated with enhanced free radical formation and blemished antioxidant defense system. The goal of study was to scrutinize impact of serum iron, total iron binding capacity (TIBC), ferritin and erythrocyte catalase in patients with beta thalassemia major. 140 beta thalassemia major patients were studied before and after supplementation of antioxidants for one month, and status was compared with 140 age and sex matched healthy controls. A significant elevation was found in the levels of serum iron and ferritin (P < 0.001) with concomitant decrease in erythrocyte catalase (P < 0.001) in patients when compared with controls. After one month supplementation of antioxidants, catalase was elevated significantly (P < 0.001) and marginal rise in serum TIBC concentration increased marginally while iron and ferritin were decreased marginally (P > 0.05) when compared with controls and baselines values. Beta thalassemia major children receive multiple blood transfusions, and are at risk of secondary iron overload induced oxidative stress. These effects may be help to minimize with supplementation of antioxidants.

The knowledge of the prevalence and molecular basis of β-hemoglobinopathies constitutes an important prerequisite for an effective prevention program. To address this issue in Iraq's capital, Baghdad, a total of 12526 individuals (6263 couples) attending three main Premarital Screening centers were enrolled. Individuals were labeled as β-hemoglobin disorders based on full blood counts and high-performance liquid chromatography.

Thalassemia is an inherited hematological disorder characterized by a decrease in the synthesis of or absence of one or more globin chains. Hepatitis E virus (HEV) is a major cause of acute viral hepatitis, constituting a major global health burden and emerging as a critical public health concern. HEV infection is mainly transmitted via the fecal-oral route; however, parenteral transmission through blood components has been reported in both developing and developed countries.

The most severe form of α-thalassemia results from loss of all four copies of α-globin. Postnatally, patients face challenges similar to β-thalassemia, including severe anemia and erythrotoxicity due to the imbalance of β-globin and α-globin chains. Despite progress in genome editing treatments for β-thalassemia, there is no analogous curative option for α-thalassemia.
