In Southeast Asia alpha-thalassemia, beta-thalassemia, hemoglobin (Hb) E and Hb Constant Spring are prevalent. The gene frequencies of alpha-thalassemia reach 30-40% in Northern Thailand and Laos. beta-Thalassemia gene frequencies vary between 1 and 9%. Hb E is the hallmark of Southeast Asia attaining a frequency of 50-60% at the junction of Thailand, Laos, and Cambodia. Hb Constant Spring gene...

Co-inheritance of alpha-thalassemia with homozygosity or compound heterozygosity for beta-thalassemia may ameliorate beta-thalassemia major. A wide range of clinical phenotypes is produced depending on the number of alpha-thalassemia alleles (-alpha/alphaalpha --/alphaalpha, --/-alpha). The co-inheritance of beta-thalassemia with alpha-thalassemia with a single gene deletion (-alpha/alphaalpha)...

BACKGROUND This study aimed to assess myocardial performance index (MPI) and arterial elasticity indices in asymptomatic patients with beta-thalassemia major without known heart disease and to determine relationship between these indices and parameters indicating iron load of body. METHODS The study included 55 asymptomatic beta-thalassemia patients (median age: 20 years (10 - 48 years)) with...

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...

BACKGROUND Due to the tropism of human parvovirus B19 to erythroid progenitor cells, infection in patients with an underlying hemolytic disorder such as beta-thalassemia major leads to suppression of erythrocyte formation, referred to as transient aplasia crisis (TAC), which may be life-threatening. We investigated the prevalence of parvovirus B19 among patients with beta thalassemia major atte...

Dermatoglyphs are cutaneous ridges on the fingers, palms, and soles, formed during early intrauterine life. During this period, and only then, genetic and environmental factors can influence their formation. Beta-thalassemia major is an genetic disease. The aim of the present work was to analyze dermatoglyphs traits in subjects with beta-thalassemia major and their thalassemia carrier parents. ...

Background: Thalassemia is one of the common inherited blood disorders and Beta Major a homozygous form deficiency beta globin chain synthesis causing severe transfusion-dependent anemia, manifesting between 6 24 months life. Objectives: The objective study to pattern cardiac function in children adolescents with beta-thalassemia major by 2D Echocardiography its correlation serum ferritin level...
