BACKGROUND The clinical and hematological response to hydroxyurea was evaluated in beta thalassemia patients in western India with variable clinical severity and correlated with genetic factors. MATERIALS AND METHODS Seventy-nine patients-[38-beta thalassemia intermedia-(group I), 41-beta thalassemia major-(group II)] on hydroxyurea therapy were(More)
OBJECTIVES Hydroxyurea is known to reduce ineffective erythropoiesis and thereby hemolysis leading to a reduction in bilirubin levels in patients with hemoglobinopathies. However, the effect of hydroxyurea on hyperbilirubinemia in relation to the UGT1A1 gene promoter polymorphism is not known in Indian patients with different hemoglobinopathies. DESIGN(More)
There is clinical variability in the presentation of sickle cell disease among Indians. Vaso-occlusive crisis is common among non-tribal patients. Hydroxyurea, induces fetal hemoglobin (HbF) synthesis and reduces the clinical severity of sickle cell disease but individual patients have a variable response. This study was undertaken to investigate the(More)
BACKGROUND X-linked hyper-IgM (XHIM) is a primary immunodeficiency disorder characterized by recurrent infections, low serum IgG and IgA and normal or elevated IgM. It results from mutations in the CD40 ligand (CD40L) gene. Confirmation of diagnosis with identification of underlying molecular defect is important for the initiation of appropriate therapeutic(More)
PURPOSE Leukocyte adhesion deficiency type-I (LAD-I) is caused by mutations in the ITGB2 gene, encoding the β2-subunit of β2-integrin (CD18) which leads to markedly reduced expression of CD18 on leukocytes resulting into recurrent life threatening infections. Here we aim to identify the molecular defects underlying LAD-I in Indian patients and correlate(More)
Adult F cell numbers are raised in inherited haemoglobin disorders, such as beta-thalassaemia and sickle cell anaemia, hereditary persistence of foetal haemoglobin, and some acquired conditions, such as juvenile myelomonocytic leukaemia, during acute erythropoietic stress and pregnancy. True foetal erythrocytes containing foetal amounts of HbF can also(More)
An accurate diagnosis of beta -thalassemia carriers, homozygous patients and identification of different structural hemoglobin variants is important for epidemiological studies as well as for management and prevention of the major hemoglobin disorders. There are many electrophoretic and chromatographic approaches for estimation of HbA2 and Hb F but cation(More)
BACKGROUND Haemoglobin E (HbE)-beta-thalassaemia has a very variable clinical presentation. The management of severe cases that are often transfusion dependent is similar to that of cases of beta-thalassaemia major; however, this is often not possible in India because of its high cost and the lack of availability of safe blood at many places. Thus there was(More)
INTRODUCTION Hb Lepore is a structurally abnormal hemoglobin in which the abnormal globin chain is a hybrid or fused δβ globin chain. In the heterozygous condition, Hb Lepore produces the phenotype of heterozygous β thalassemia with slightly raised HbF levels. METHOD Using a combination of HPLC and DNA analysis, we have identified eight individuals with(More)
