BACKGROUND Oxidative stress may aggravate symptoms of hemolytic anemias such as beta-thalassemia. FoxO3 activation results in resistance to oxidative stress in fibroblasts and neuronal cell cultures. OBJECTIVE The purpose of this research was to study FoxO3 gene expression and oxidative status in beta-thalassemia minor individuals. METHODS Sixty-three subjects (42 apparently healthy individ...
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 stu...
In this article we report a Sardinian family, in which a beta-thalassemia gene and a triple alpha-globin loci, counterpart of the rightward deletion type alpha-thalassemia-2, were segregating. The analysis of the genotype-phenotype correlations in the different family members allowed us to give an outline of the manifestations associated with different genotype combinations. The heterozygote fo...
BACKGROUND Thalassemia major has become a public health problem worldwide, particularly in developing and poor countries, while the role of educating the family and community has not been considered enough in patients' care. OBJECTIVES This study examines the impact of partnership care model on mental health of patients with beta-thalassemia major. MATERIALS AND METHODS This experimental st...
introduction: leptin is an adipocyte-derived hormone. exogenous leptin allows the recovery of the reproductive function. in humans, leptin correlates positively with the body mass index (bmi). the aim of this study was to investigate the association of leptin with the toxic effects of iron overload. methods: 219 major beta thalassemic patients (119 men, 100 women) and 137 non thalassemic indivi...
background polypeptide hormone leptin suppresses inflammation in the heart muscle and protects heart from diseases. the purpose of this study is to evaluate the relationship between leptin and troponin serum levels with cardiac involvement in patients with major beta thalassemia. materials and methods in this cross-sectional study, 70 children with major thalassemia were selected. two ml blood ...
beta-Thalassemia and sickle cell disease both display a great deal of phenotypic heterogeneity, despite being generally thought of as simple Mendelian diseases. The reasons for this are not well understood, although the level of fetal hemoglobin (HbF) is one well characterized ameliorating factor in both of these conditions. To better understand the genetic basis of this heterogeneity, we carri...
DOI: 10.5581/1516-8484.20110128 Thalassemias are common monogenic disorders caused by partial or complete reduction synthesis of one or more globin chains.(1) The normal concentrations of fetal hemoglobin (Hb F) in adults without Hb alterations range from 0% to 1%.(2) It is known that stimulation of Hb F production is beneficial to homozygous beta-thalassemia individuals(3) and that the XmnI po...
The presence of various substitutions and deletions resulting in beta-thalassemia was studied in 19 black patients with homozygous beta-thalassemia and in numerous relatives; all patients were from Georgia, South Carolina, and Alabama. Methodology included gene mapping, amplification of genomic DNA with Taq polymerase, identification of known nucleotide substitutions or a single nucleotide dele...
BACKGROUND Sickle cell trait (SCT) is the heterozygous form of sickle cell disease and expectedly should be a benign state with no complications ascribed to it. There are numerous reports challenging its being a benign condition, though this is controversial. METHODS AND RESULTS A review of the results of the accompanying investigations done on some of the patients show that beta thalassemia ...
