BACKGROUND Though regular blood transfusion improves the overall survival of patients with beta-thalassemia, it carries a definite risk of infection with blood-borne viruses. We carried out this multicenter study to provide epidemiologic data on hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection among Iranian beta-thalassemic patients. Moreover, H...

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 ...

BACKGROUND Thalassemia is a heterogeneous disorder and several genetic factors influence the severity of thalassemia. An accurate and early diagnosis of a mild thalassemia genotype helps to avoid unnecessary transfusion and its complications. The aim of this study is to identify the association between XmnI polymorphism and disease severity in patients with beta-thalassemia from northern Pakist...

Abstract A group of inherited blood defects is known as Thalassemia among the world’s most prevalent hemoglobinopathies. Thalassemias are two types such Alpha and Beta Thalassemia. The cause these gene mutations leading to low levels and/or malfunctioning ? ? globin proteins, respectively. In some cases, one proteins may be completely absent. chains form a fold or pocket for heme (Fe++) attachm...

BACKGROUND: Thalassemia is the most common hereditary disease in the world. Thalassemic erythrocytes are exposed to higher oxidative stress and lipid peroxidation. The aim of this study was to investigate the effects of beta-carotene and vitamin E on erythrocytes lipid peroxidation in beta-thalassemia patients. METHODS: A prospective double-blind, placebo-controlled study of the effect of beta-...

BACKGROUND Chitotriosidase is a functional chitinase secreted by activated macrophages, which is extremely increased in plasma of patients with Gaucher disease (beta-glucocerebrosidase deficiency). Recently, we found that chitotriosidase plasma levels were increased to a variable extent in Sicilian patients with beta-thalassemia major. The aim of this study is to elucidate the possible mechanis...

  Inroduction: Heart failure (HF) is an important cause of morbidity and mortality in the cases of Beta-thalassemia major. The purpose of this study was to estimate HF prevalence in these patients and to assess the survivability of those who were treated with intensive chelating therapy.   Design and methods: This cross sectional study included 72 beta-thalassemia major cases, the mean age at t...

OBJECTIVE Four combinations of five neutral sequence changes at rs713040, rs10768683, rs7480526, rs7946748, and rs1609812 occurring in the human beta globin gene defined as frameworks have been reported in beta globin gene. Here we report for the frequency of these frameworks in thalassemia major patients of North Iran. METHODS Beta globin gene frameworks of 46 thalassemia major patients of N...

Background: Quality of life (QoL) is a complicated phenomenon in patients with thalassemia major. This study was conducted to clarify the concept of QoL in patients with thalassemia major. Materials and Methods: This study was performed using Roger’s evolutionary method. Electronic databases:<...

Background: β-thalassemia as a hereditary disease is defined as defective synthesis of   β-globin chains, resulting in erythropoiesis abnormalities and severe anemia. Different studies have shown that cytokines and cytokine gene polymorphisms play a major role in the pathogenesis of   β-thalassemia. Single nucleotide polymorphisms (SNPs) within the promoter region or other regulatory sequences ...
