Iron overload results in significant morbidity and mortality in β-thalassemic patients. Insufficient hepcidin is implicated in parenchymal iron overload in β-thalassemia and approaches to increase hepcidin have therapeutic potential. We have previously shown that exogenous apo-transferrin markedly ameliorates ineffective erythropoiesis and increases hepcidin expression in Hbb(th1/th1) (thalasse...

Background and Objectives. In non-thalassaemic women serum erythropoietin (Epo) level increases during pregnancy, whereas that of soluble transferrin receptor (STFR) drops slightly in the first two trimesters to attain the original values in the third trimester. In this study the time-course of these two parameters was explored in β-thalassemic and nonβ-thalassemic women, both pregnant and not.

OBJECTIVE There are some reports in which a condition of zinc deficiency and its associated outcomes with a change in concentration of serum copper among the thalassemic patients has been highlighted. The aim of this prospective study was to determine the serum zinc and copper levels in children with beta-thalassemia major. METHODS In this cross sectional study all children under 12 years aff...

Human parvovirus B19 infection was studied in 60 thalassemic patients in Thailand. Seroprevalence, persistence of parvovirus B19 and their genotypes were identified in blood samples. Prevalence of anti-parvovirus B19 IgG and DNA found in thalassemic patients were 38% and 13%, respectively. Anti-parvovirus B19 IgM could be detected in 4% of these positive anti-parvovirus B19 IgG patients. The se...

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 ...
