background: many efforts have been undertaken until now to find an alternative approach to packed red cell tranfusion in major β-thalassemia. augmentation of fetal hemoglobin by hydroxyurea has proved to be less effective in this condition as compared to sickle cell anemia, probably due to molecular heterogeneity of the former disease. hydroxyurea efficacy and its relation to xmn1 polymorphism ...

β- thalassemia major is a common hemoglobinopathy in humans. in some journals, numerous studies have reported different prevalence of hepatitis c among β- 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 β- thalassemia major...

abstract β-thalassemia major (β –tm) is the most common thalassemia severe phenotype among iranians. in recent years, molecular understanding of pathogenesis of β –tm has provided a great opportunity regarding diagnostic issues. creating comprehensive molecular databases provides highly sensitive diagnostic tools for β –tm and effective prenatal diagnosis (pnd) molecular screening tests. despit...

early and regular blood transfusion therapy in patients with homozygous beta-thalassemia decreases the complications of severe anemia and prolongs survival. in the long term, however, the beneficial effects of transfusions are limited by the organ damage resulting from iron overload. endocrine complications in patients with thalassemia major in developing countries may be frequent due t o subop...

background: β-thalassemia is an autosomal hemoglobinopathy with inconsistent universal distribution. among patients with thalassemia diverse non-siderotic complications distinctly influence the attribute of life, including zinc deficiency due to varied etiologies. the objective of the present study was to determine zinc levels in patients with β-thalassemia major and its correlation with matern...

background: thalassemia syndromes are the most prevalent single gene disorders in iran. this study aimed to evaluate the effect of different types of beta-globin gene mutations, co-inheritance of alpha-globin gene mutations and/or xmn1 snp on disease phenotype in a large cohort of iranian patients. subjects and methods: in total, 433 patients were clinically classified into β-thalassemia major ...

background: in recent years, the success in management of thalassemic patients, has allowed for some previously unrecognized complications including renal abnormalities to emerge. this prospective study aimed to investigate kidney iron overload by means of mri t2* and also renal function based on laboratory tests for early markers of glomerular and tubular dysfunction among adult iranian transf...

background: β-thalassemia major is a hereditary life threatening anemia which requires regular blood transfusion. clinical symptoms of the disease are growth retardation, pallor, jaundice and skeletal alternations. the variety of bone disease in thalassemia major is manifested by diffuse bone pain or deformity, spontaneous and pathologic fractures and osteopenia or osteoporosis. this study aime...

background: patients with β-thalassemia major (tm) develop iron overload through increased iron absorption and transfusional therapy and it’s the most important complication of tm. thalassemia is common in coastal regions and lands with low altitudes. the aim of this study is to determine the effect of high and low altitude on serum ferritin and treatment requirement in two groups of β-thalasse...

background: thalassemia syndromes are the most common genetic disorders in the world. they happen due to genetic defects in process of haemoglobin synthesis, and would be classified to many groups mainly α and β, based on the kind of defect. anemia is the main clinical manifestation of this phenotype of disorder. in order to correct the chronic anemia in thalassaemic individuals, they may need ...
