Thalassemia associates anemia and iron overload, two opposite stimuli regulating hepcidin gene expression. We characterized hepatic hepcidin expression in 10 thalassemia major and 13 thalassemia intermedia patients. Hepcidin mRNA levels were decreased in the thalassemia intermedia group which presented both lower hemoglobin and higher plasma soluble transferrin receptor levels. There was no rel...

I enjoyed reading Bilgen et al.’s case report, The effect of HBB: (c*+96T>C (3’UTR+1570 T>C) on the mild β-thalassemia intermedia pheonotype, in the recent issue of the Journal (2011; 28: 219-222). I congratulate the authors for exploring at the molecular level at least one of the thalassemia minima that fits well with the present clinical thalassemia nomenclature. Based on their clinical descr...

To define how excess unpaired alpha- and beta-globin chains in severe beta-thalassemia and severe alpha-thalassemia interacting with the membrane might alter cellular and membrane properties, we performed a series of biophysical and biochemical analyses on erythrocytes obtained from affected patients. Detailed analysis of cellular and membrane deformability characteristics showed that both form...

In this study, we aimed to determine the frequency of red cell allo- and autoimmunization and analyze the factors responsible for the development of antibodies in patients with transfusion-dependent thalassemia. This crosssectional study was conducted on 139 patients with thalassemia major and intermedia who received leukodepleted RBC transfusions on a regular basis. Patients with a positive an...

introduction: thalassemia is common in iran. appropriate therapy for this disease includes a regular blood transfusion and chelation therapy. however, patients will inevitably confront with side effects, particularly iron overloads in critical organ including heart, ductless glands and liver. this study tries to determine the prevalence of diabetes mellitus in transfusion dependent β thalassemi...

The color complementation assay (CCA) is a method of allele-specific DNA amplification by which competitive priming and extension of fluorescently labeled oligonucleotide primers determine the color of DNA amplification product. This diagnostic method precludes the need for radioisotopes, electrophoresis, and multiple high-stringency reaction conditions. The multiplicity of mutant globin genes ...

CONTEXT We verified molecular alterations in a 72-year-old Brazilian male patient with a clinical course of homozygous beta-thalassemia intermedia, who had undergone splenectomy and was surviving without regular blood transfusions. The blood cell count revealed microcytic and hypochromic anemia (hemoglobin = 6.5 g/dl, mean cell volume = 74 fl, mean cell hemoglobin = 24 pg) and hemoglobin electr...

BACKGROUND Beta-thalassemia is considered to be the most frequent hereditary blood disorder worldwide. Lipid abnormalities have been detected in different types of beta-thalassemia. The aim of this study is to assess the lipid profiles in beta-thalassemia major (BTM) and beta-thalassemia intermedia (BTI) patients in southern Iran. METHODS The study group consisted of 55 BTM patients and 50 BT...
