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...

The conventional approach to qualitative and quantitative analyses of hemoglobin (Hb) molecules for the diagnoses of hemoglobinopathies requires a combination of tests. We used an automated HPLC (VARIANT) system to study alpha-thalassemia and beta-thalassemia syndromes in Thailand. The beta-thalassemia short program is applicable to the diagnosis of alpha-thalassemia and beta-thalassemia disord...

BACKGROUND Beta thalassemia is one of the most common genetic disorders in the world. The aim of this study was to determine the frequency, characteristics, and pattern of malignancies in patients with beta thalassemia major (BTM) and beta thalassemia intermedia (BTI) in Iran. METHODS We conducted a multicenter study via a retrospective chart review of patients with BTM and BTI between 2002 a...

background :highserum level of cancer antigen 15.3 (ca15.3) has been reported in some malignant and nonmalignant conditions including thalassemia major which could have been resulted from ineffective erythropoiesis. we aimed to evaluate the serum level of ca15.3 in carriers of beta-thalassemia by comparing them with cancer patients and healthy individuals.   methods : this cross-sectional study...

beta-thalassemias are the most common single gene disorders and are potentially amenable to gene therapy. However, retroviral vectors carrying the human beta-globin cassette have been notoriously unstable. Recently, considerable progress has been made using lentiviral vectors, which stably transmit the beta-globin expression cassette. Thus far, mouse studies have shown correction of the beta-th...

Functional messenger RNA for human hemoglobin synthesis was prepared from reticulocyte lysates of patients with homozygous beta thalassemia and sickle cell anemia. The messenger RNA stimulated the synthesis of human globin chains by a cell-free system derived from Krebs mouse ascites cells. In the presence of beta thalassemia messenger RNA, the system synthesized much less beta chain than alpha...

BACKGROUND & OBJECTIVE Alpha (α) thalassemia is a hereditary disorder and is caused by deletions or mutations in globin genes. It is present in two clinically significant forms: hemoglobin Bart hydrops fetalis (Hb Bart) syndrome and hemoglobin H (HbH) disease. It is highly prevalent in South-East Asia or Mediterranean countries. The most common deletion reported in alpha thalassemia in Pakistan...

Thalassemia is a congenital hemolytic disorder caused by a partial or complete deficiency of alpha- or beta-globin chain synthesis. Homozygous carriers of beta-globin gene defects suffer from severe anemia and other serious complications from early childhood. The disease is treated by chronic blood transfusion. However, this can cause severe iron overload resulting in progressive organ failure....
