BACKGROUND: β-thalasemia major (β-TM) patients often suffer from various vascular complications together with increased oxidative stress. Hyperhomocysteinemia (Hhcy) has been defined as a risk factor for these complications. Genetic polymorphism of methylenetetrahydrofolate reductase (MTHFR) C677T has been shown to cause Hhcy particularly in individuals with low B-vitamins. However, the status of homocysteine (hcy) in β-TM has not yet been adequately defined. AIM: To evaluate the genetic polymorphism of MTHFR C677T among β-TM patients and its prospective contribution to Hhcy and related oxidative changes...

Diamond-Blackfan Anemia (DBA) is a bone marrow failure disorder characterized by low red blood cell count. Mutations in ribosomal protein genes have been identified in approximately half of all DBA cases. Corticosteriod therapy and bone marrow transplantation are common treatment options for patients; however, significant risks and complications are associated with these treatment options. Therefore, novel therapeutic approaches are needed for treating DBA. Sotatercept (ACE-011, and its murine ortholog RAP-011) acts as an activin receptor type IIA ligand trap, increasing hemoglobin and hematocrit in pharmacologic models, in healthy volunteers, and in patients with β-thalassemia, by expanding late-stage erythroblasts through a mechanism distinct from erythropoietin...

Among the many associated features of persistent pulmonary hypertension of the neonate (PPHN), severe congenital anemia has been described only occasionally and is not included in the list of conditions that may cause PPHN in the neonate. We describe the clinical course of a group of 12 full-term neonates with PPHN and congenital anemia due to congenital dyserythropoietic anemia (7/12), α thalasemia (1/12), Diamond-Blackfan (1/12), and epsilon gamma delta beta thalassemia (3/12). The association of congenital anemia and PPHN is more common than previously thought; it can exist with various etiologies and severity of anemia...

BACKGROUND: β -Thalassaemia, an autosomal recessive hemoglobinopathy, is one of the commonest genetically transmitted disorders throughout the world. Collective measures including carrier identification, genetic counseling and prenatal diagnosis are required for preventing β-thalassemia. AIM: To achieve this objective, Identification of the spectrum of genetic mutations, especially for various ethnic backgrounds in Pakistan. Therefore, we designed a cross sectional prospective study to identify the frequency of various gene mutations in different ethnic groups of Pakistan...

BACKGROUND: Noninvasive prenatal diagnosis based on detection of fetal cell-free DNA is hampered when mother and father are both carriers for the same autosomal recessive mutation. OBJECTIVE: To compare the diagnosis of Bart's hydrops fetalis using conventional Gap-PCR analysis of fetal cells/tissues with the measurement of quantitative difference (deltaCp) between alpha-thalassemia-1 SEA type deletion gene (C(T-mutant)) and wild type alpha-globin gene (C(T-wild type)) in plasma of pregnancies by using the Taqman real-time quantitative PCR...

Need for iron increases rapidly during adolescence. In girls, this is primarily due to the beginning of menstruation and dieting to loose weight, while in boys increased erythropoetic activity during pubertal period is the major cause. Between November 1999 and June 2000, 2,900 patients, between 9-17 years of age were screened for the presence of anemia in our Adolescent Outpatient Clinic. Tanner's scale of sexual maturation was used to categorize genital development. Those patients diagnosed with anemia were further examined for bone age, history of pica, parasitosis and gastrointestinal symptoms...

George Hoyot Whipple (1878-1976) was awarded the Nobel Prize in Physiology and Medicine in 1934, along with Minot and Murphy for their studies in pernicious anemia. Whipple's name has been given to the bacterial disease which he describes in 1907 that we know today as Whipple's disease or intestinal lipodystrophy. He gave the name of thalasemia to the Mediterranean anemia of Cooley, and made diverse contributions to hematology and general pathology. He worked with William Welch in the Department of Pathology at Johns Hopkins Hospital and later became director of the University of Rochester...

Hydroxyurea is a common cancer chemotherapy agent that inhibits ribonucleotide reductase, an enzyme essential to DNA synthesis. It is considered the drug of choice in the treatment of chronic myelogenous leukemia and essential thrombocythemia. The occurrence of leg ulcers have been described in 8.5% of patients receiving continuous treatment with hydroxyurea, but the cause of this complication is unknown. We report two additional patients and suggest that macroerythrocytosis, which occurs in almost all the patients taking hydroxyurea, may be a pathogenic factor...

Thalassemia intermedia is a clinical entity characterized by moderate, non-transfusional anemia and hepatosplenomegaly. This phenotype can result from different genetic combinations and is sometimes present in patients with only one parent showing the thalasemia minor phenotype. We report here a family with seven members with the thalassemia beta trait, four of them with thalasemia minor and the other three with thalassemia intermedia. The genetic study of patients with thalassemia intermedia revealed the presence of the mutation IVS-1 1(G-->A) in the beta-globin gene and the heterozygous triplication of the alpha-globin gene, an uncommon association in Spain...

In contrast to findings in the thalasemia syndromes, studies of globin synthesis in subjects with structurally abnormal hemoglobins have generally revealed equal production of alpha and beta polypeptide chains. However, in the present investigation of globin biosynthesis in vitro in blood and marrow from two subjects heterozygous for unstable hemoglobin Leiden, beta6 or 7 Glu --> O, a significant excess of alpha-chain production was revealed. A mother and daughter of northern European ancestry with mild compensated hemolytic anemia were found to have 25% hemoglobin Leiden...
