BACKGROUND β-thalassemic syndromes are inherited red cell disorders characterized by severe ineffective erythropoiesis and increased levels of reactive oxygen species whose contribution to β-thalassemic anemia is only partially understood. DESIGN AND METHODS We studied erythroid precursors from normal and β-thalassemic peripheral CD34(+) cells in two-phase liquid culture by proteomic, reverse...

This study designed to analyzed humoral response related to measuring the serum levels of immunoglobulines (IgG , IgM and IgA) and complements corporeats ( C3 and C4) in (20) thalassemic patient and (10) control subject. IgG only recorded a high significant differences between two studied group – whereas no significant differences were found in levels of remaining humoral components ( IgM , IgA...

Background: Retarded growth in thalassemic patient is complex and multi-factorial, it includes chronic hypoxia secondary to anemia when pre-transfusion haemoglobin below 9 g/dl. Development of sexual characteristics children markedly delayed as compared their non-thalassemic siblings the expected development criteria due iron overload. The main objective present study monitor these patients lon...

Hemoglobinopathies have a protective role in malaria that appears to be related to alterations in red blood cell (RBC) properties. Thalassemic RBCs infected with Plasmodium falciparum showed greatly reduced cytoadherence and rosetting properties as well as impaired growth and multiplication. A significant decrease in the levels of falciparum antigens associated with the membrane of infected bet...

Genetic mutations that block aor b-globin gene expression in humans can result in severe and frequently lethal thalassemic phenotypes. Homozygous inactivation of the endogenous aor b-globin genes in mice results in corresponding thalassemic syndromes that are uniformly fatal in utero. In the current study, we show that the viability of these mice can be rescued by expression of human embryonic ...

BACKGROUND The objective of this study is to evaluate the prevalence of malocclusion and treatment needs in transfusion dependent β-thalassemia major children. METHODS One hundred transfusion dependent β-thalassemia major children visiting the Department of Pediatrics were selected randomly and evaluated for malocclusion with Angle's classification and Dewey's modification. The orthodontic tr...

β-Thalassemias are a group of hereditary blood disorders characterized by abnormalities in the synthesis of the β hemoglobin (Hb) chains. This disease causes excessive storage of iron in all organs and endocrine glands. Treatment of β-thalassemia major (β-TM) consists of regular blood transfusions, iron chelation and management of secondary complications of iron overload. Endocrine abnormalitie...
