From 362 thalassemia cases referred to adult thalassemia clinic of the Iranian blood transfusion organization (IBTO) for genotyping, 103 cases (28.5%) had a common primary disease factor, IVSII-1 mutation in homozygous state. 61 (59.2%) of these individuals represented thalassemia major and 42 (40.8%) thalassemia intermedia clinical phenotype.

BACKGROUND Blood safety is important in all transfusion centers. The aim has always been to try to guarantee the recipient's safety through careful screening and examination of donors' blood samples. In Iran the hepatitis C virus (HCV) screening test became mandatory for blood donations from 1996. We decided to determine the incidence of new cases of HCV in(More)
Hydroxyurea (HU), a drug which can reactivate fetal hemoglobin (Hb F) production, is frequently prescribed to β-thalassemia (β-thal) patients. However, transfusion requirements of only a subset of patients are reduced upon HU treatment. Because of its potential side-effects, targeted prescription of HU is imperative. To identify genetic markers that(More)
Alpha thalassemia (alpha-thal) is one of the most common hemoglobin (Hb) disorders in the world. Alpha-globin genes are located on chromosome 16. The majority of alpha-thal mutations are deletions but point mutations are found as well. Since the Iranian population is a mixture of different ethnic groups, frequency and distribution of alpha-globin mutations(More)
Beta-thalassemia major is a severe, transfusion-dependent anemia that also causes infertility due to iron deposition to endocrine organs after overtransfusion. Very few pregnancies have been reported among such patients after modern therapies. In this study, 32 women with thalassemia who were admitted to Ali Asghar Children's Hospital and Thalassemia Clinic(More)
BACKGROUND Using two logistic regression models, we determined the associates of poor physical and mental health related quality of life (HRQoL) among beta thalassemia patients. METHODS In this cross-sectional study which was conducted during 2006 and 2007 in outpatient adult thalassemia clinic, Blood Transfusion Organization, Tehran, Iran, Short Form 36(More)
The authors investigated the prevalence of low bone mass in patients from Tehran, Iran, with beta-thalassemia major (n = 203), aged 10-20 years, and the potential risk factors for osteoporosis in this patient population. Prevalence of osteoporosis was 50.7% in lumbar spine, 10.8% in femur, and 7.9% in both regions with no significant difference between the(More)
Exposure of cells to chemotherapeutic drug doxorubicin, a DNA-damaging agent, induces an increase in the levels and activity of the wild-type p53 protein. Less well appreciated was the effect of cAMP levels on posttranslational modifications of p53 in response to doxorubicin. Here we show that elevation of cAMP in pre-B acute lymphoblastic leukemia NALM-6(More)
To study the influence of the β globin locus control region (LCR) genotypic background on the phenotype modifying role of BCL11A polymorphisms, 100 cases of thalassemia, 48 homozygous for the A allele and 52 homozygous for the G allele at the 5'HS4-LCR palindromic polymorphic site were genotyped for two BCL11A single nucleotide polymorphisms (rs11886868 and(More)
INTRODUCTION Hypercoagulable state is one of the common findings in beta-thalassemia intermedia (β-TI), particularly in splenectomized patients, with infrequent blood transfusion. Abnormality of the red blood cells (RBC) membrane due to oxidative damage is suggestive of possible etiologies. Membrane lipid peroxidation increases the exposure of(More)
