BACKGROUND: Type 1 diabetes mellitus described as a chronic metabolic disorder characterized by aggressive immune β-cell destruction. There are numbers of varied immune mechanisms for sustaining self-tolerance in opposition to the autoimmune disorders. A recessive tolerance accomplished by thymic gland via a negative assortment of different clones while a dominant tolerance accomplished by the regulatory T cells (Treg) in the periphery. Treg (CD4+CD25+FOXP3+) are subsets of T cells which have an essential role in maintaining tolerance...

Increasing evidence supports the existence of a close relationship between immunotransfusion, hemostasis, and thrombosis. The best example of such linkage is given by the influence of the ABO blood group antigens on von Willebrand factor (VWF) plasma levels and activity. It is well known, for instance, that individuals with non-O blood type (i.e., A, B, and AB) have higher VWF and factor VIII plasma levels than O blood type subjects and are consequently exposed to an increased thrombotic risk. There is also a close relationship between immunotransfusion, hemostasis, and thrombosis testing...

Objectives Although non-O blood type is an established risk factor for venous thromboembolism in the general population, the impact of ABO blood type (ABO) on venous thromboembolism risk in individuals with persistent antiphospholipid antibodies (aPL) has not been studied. We sought to investigate the relationship between ABO and venous thromboembolism in aPL-positive individuals. We also sought to explore potential interactions between ABO and sex or race to determine whether ABO contributes to race or sex differences with respect to the development of venous thromboembolism...

ABO blood types are associated with the prognosis of several malignancies. However, the role of the ABO blood type in hepatocellular carcinoma (HCC) remains elusive. Here, we evaluated the prognostic role of the ABO blood group in 691 HCC patients after hepatectomy by Cox regression analysis. A prognostic nomogram was generated to predict the 3 and 5-year overall survival (OS). A total of 262 HCC patients (37.9%) had blood group O, 199 (28.8%) had blood group A, 165 (23.9%) had blood group B, and 65 (9.4%) had blood group AB...

Passenger lymphocyte syndrome is a rare but important disease in which the donor lymphocytes produce antibodies to the red blood cell antigens of the recipient, causing alloimmune hemolysis. It occurs in ABO blood group-mismatched solid-organ and/or bone marrow transplant. We report a case of passenger lymphocyte syndrome occurring after ABO-incompatible kidney transplant. The recipient received rituximab as a desensitization protocol. On posttransplant day 18, the recipient showed a fall in her hemoglobin levels without identifiable bleeding source and an elevation of total bilirubin...

INTRODUCTION: Landsteiner ABO system of blood groups is most important for transfusion medicine and has subtypes of A Antigen, A1 and A2, upon which further groups of A and AB have been classified. Of individuals with A antigen, approximately 20% belong to A2 while rest 80% belong to A1. Anti-A1 Lectin, a cold agglutinin which destroys A1 cells is clinically significant when they react at 37°C, causing transfusion reactions. AIM: To assess the prevalence of A1 and A2 subgroups in the population...

Patient samples are routinely typed for ABO prior to transfusion. Determining the ABO group requires both red blood cell (RBC) antigen typing for A and B (forward type) and testing for anti-A and anti-B in the plasma (reverse type). An ABO discrepancy exists when the result of an ABO RBC typing, or forward type, does not agree with the result of the plasma typing, or reverse type. This brief review examines several causes of ABO discrepancies encountered in the clinical transfusion service. Options for resolving these discrepancies are presented, including a discussion of which discrepancies should be resolved using molecular testing...

The presence of the FORS1 antigen on red blood cells was discovered relatively recently, and in 2012, the International Society of Blood Transfusion (ISBT) acknowledged FORS as blood group system number 031. This rare antigen is carried by a glycosphingolipid and formed by elongation of the P antigen. Most people have naturally occurring anti-FORS1 in their plasma. The clinical significance of these antibodies is unknown in the transfusion setting, but they can hemolyze FORS1+ erythrocytes in the presence of complement in vitro...

BACKGROUND: The amino acid substitutions caused by ABO gene mutations are usually predicted to impact glycosyltransferase's function or its biosynthesis. Here we report an ABO exonic missense mutation that affects B-antigen expression by decreasing the mRNA level of the ABO gene rather than the amino acid change. STUDY DESIGN AND METHODS: Serologic studies including plasma total GTB transfer capacity were performed. The exon sequences of the ABO gene were analyzed by Sanger sequencing...
