Beta thalassemia is an autosomal recessive disorder characterized by reduced (beta(+)) or absent (beta(0)) beta-globin chain synthesis. In Lebanon it is the most predominant genetic defect. In this study we investigated the religious and geographic distribution of the beta-thalassemia mutations identified in Lebanon, and traced their precise origins. A total of 520 beta-globin chromosomes from ...

One of the genetic features of the Sardinian population is the high prevalence of hemoglobin disorders. It has been estimated that 13% to 33% of Sardinians carry a mutant allele of the alpha-globin gene (alpha-thalassemia trait) and that 6% to 17% are beta-thalassemia carriers. In this population, a single mutation of beta-globin gene (Q39X, beta(0) 39) accounts for >95% of beta-thalassemia cas...

Background and Objectives: Beta-thalassemia continues to be a cause of significant burden to the society particularly in the poorer developing countries. Although sophisticated methods of screening have become available, a hunt for a cheap, rapid, objective screening method still remains elusive. Thus, the objectives are to study the validity of Naked-Eye-Single-Tube-Osmotic-Fragility-Test (NES...

Background and Aim: Beta-thalassemia ( -thalassemia) is characterized by the reduced synthesis of the hemoglobin beta chain. Nowadays, more than 200 disease-causing mutations in beta-globin ( -globin) gene have been identified. Betathalassemia is the most common monogenic disease worldwide and one of the widespread hereditary disorders in Iran. Considering the vast spectrum of beta-thalassemia ...

abstract background prevalence of hereditary blood diseases such as sickle cell anemia, sickle thalassemia and thalassemia major are high in khuzestan province. sickle cell anemia and beta-thalassemia are predominantly common in iranian arabs. pulmonary complications account for a large proportion of morbidity and mortality in patients with and sickle cell disease. periodic lung function assess...

Upon erythroid cell maturation in vivo, beta-thalassemic erythroid cells accumulate unmatched unstable alpha-globin chains that are believed to be a causal factor in such cell destruction. This study showed that beta-thalassemia/Hb E erythroid precursor cells from peripheral blood had accelerated maturation, and could mature to the terminal erythroid stage. During the early period of cell cultu...

Thalassemia is a group of inherited blood disorders due to the reduction or absence globin chain synthesis which can cause hemolytic anemia. β-thalassemia major severe type thalassemia, in patients require lifelong transfusions for survival. Extravascular hemolysis on spleen results splenomegaly, meanwhile, extramedullary hematopoiesis causing hypersplenism develop beta-thalassemia patients. Hy...

beta- thalassemia major is a common hemoglobinopathy in humans. In some journals, numerous studies have reported different prevalence of hepatitis C among beta- thalassemia major because thalassemic patients need multiple blood transfusions and blood transfusion is a common transmission pathway for hepatitis C virus. Thus this study was performed for detection of anti-HCV between beta- thalasse...

Beta thalassemia, characterized by the deficiency or the absence of beta globulin production, is the most widespread inherited disorder in the world and is also common in Turkey. To determine the prevalence of carriers for beta thalassemia, we screened the couples before their marriage. For this aim, from 1994 to 1999, a total of 14.200 people were screened. The complete blood count and red blo...

  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...
