BACKGROUND Although several studies have investigated the association between ABO blood type and risk of gastric cancer (GC), atrophic gastritis (AG), and Helicobacter pylori (HP) infection, no study has investigated these associations by using ABO genotype. METHODS We conducted a case-control study in 703 patients with GC and 1,465 noncancer patients. We also conducted a cross-sectional stud...

BACKGROUND Data on frequency distribution of ABO-Rh blood groups in cardiac syndrome X (CSX) patients are not available. We aimed to investigate the distribution of ABO-Rh blood groups in these patients. MATERIALS AND METHODS A total of 247 CSX patients' records were reviewed in a cross-sectional study from 2006 to 2010. One hundred forty six patients (59.1%) were female, and the mean patient...

BACKGROUND The ABO blood group is reported to be associated with the incidence and patient survival for several types of malignancies. We conducted a retrospective study to evaluate the prognostic significance of the ABO blood group in patients with resected non-small cell lung cancer (NSCLC). METHODS A total of 333 patients (218 men and 115 women) with resected NSCLC were included in this st...

We report nine donations with ABO inconsistency in reverse typing caused by partly or entirely missing antibodies. A and B antigens and antibodies were examined by serological blood typing, and ABO deoxyribonucleic acid (DNA) analyses were performed by sequence-specific priming and sequencing. A B101 allele was demonstrable in a case with O phenotype. The molecular mechanisms in deficiency of n...

Background. Determination of the various ABO/Rh blood group distributions and their association with malaria infection has paramount importance in the context of transfusion medicine and malaria control. Methods. Facility based cross-sectional study was conducted from February to June, 2015, to assess ABO/Rh blood groups distribution and their association with asymptomatic malaria. A structured...

SUMMARY: BACKGROUND: The gene locus for the ABO blood group system encodes a glycosyltransferase. Alterations in the DNA sequence are associated with the blood groups and the expression levels of antigens on red blood cells. A number of ABO alleles have been described as the molecular basis of weak A or B antigens. PATIENTS AND METHODS: Here, we describe a novel variant B allele in a blood dono...

The role of the ABO blood group system in determining the outcome of bone marrow transplantation was investigated in 53 patients with aplastic anemia and acute leukemia grafted from HLA-identical siblings. There was no correlation between ABO compatibility and marrow engraftment, graft rejection, or graft-versus-host disease. In 5 recipients with antibodies prior to transplantation to antigens ...

BACKGROUND A new protocol for ABO-incompatible kidney transplantation has recently been introduced. We report here on the joint experience of the implementation in Stockholm and Uppsala, Sweden and Freiburg, Germany. METHODS The new protocol utilizes antigen-specific immunoadsorption to remove existing ABO-antibodies, rituximab, and intravenous immunoglobulin to prevent the rebound of antibod...

E-mail: satyamarora83@ gmail.com For a long time, it has been thought that matching of ABO blood groups is an absolute requirement for successful solid organ transplants (SOT). In the last few years, however, se...

INTRODUCTION Recently, numerous studies have been carried out to explain the genetics and immunopathogenesis of Behçet's disease (BD). There is still insufficient understanding of its etiopathogenesis, but substantial genetic and immune system abnormalities have been suggested. Several studies have shown remarkable associations of ABO blood groups with various diseases. This study investigated ...
