background beta-thalassemia patients receive blood products from blood transfusion centers repeatedly. blood transfusion can transmit cytomegalovirus (cmv) and toxoplasma gondii. the aim of this study was serological evaluation of these two infectious agents in thalassemia patients. materials and methods in a cross-sectional study, the enzymelinked immunosorbent assay (elisa) testing was perfor...

A sentinel study on viral hepatitis is currently being carried out in the village of Cavunge in a semiarid rural region of the state of Bahia, northeastern Brazil. This study has identified individuals in whom anti-HBc IgG was the only serological marker for hepatitis B virus (HBV). This serological pattern may constitute evidence of occult HBV infection. This study Investigated the possibility...

A prospective study was conducted to identify and characterize hospitalizations for acute exacerbations of chronic obstructive pulmonary disease (AECOPD) with serological evidence of infection with Legionella spp. (Lsp). Two-hundred and forty hospital admissions for AECOPD of 213 patients were included in the study. Paired sera were obtained for each of the admissions and were tested for 41 dif...

INTRODUCTION The aetiology of recurrent aphthous stomatitis (RAS) remains unknown. An association between RAS and coeliac diseases (CD) has previously been suggested, but the supporting evidence remains equivocal. The aim of the present study was to determine the likely frequency of CD in a large cohort of patients with well-defined RAS, by detailed haematological and serological analysis, incl...

Objectives: Accurately identifying the Antigens (Ags) on recipient red blood cells (RBCs) is critical in prevention of RBC alloimmunization in chronically transfused patients. The goal of this study was to compare RBC molecular genotyping to serological phenotyping in those patients. Methods: Serological phenotyping and molecular genotyping methods were used to study blood samples from 18 healt...
