BACKGROUND AND OBJECTIVES: A lateral flow assay for simultaneous blood group typing of ABO, RhD, C, E, c, e, Cw and K with stable end-point and without centrifugation is in routine use since several years (MDmulticard(®) ). The typing of extended phenotype parameters belonging to the Duffy, Kidd, MNSs blood group systems and others, however, has not yet been demonstrated for this technique. Reliable detection of Fy(x) , a weak Fy(b) phenotype with a pronounced quantitative reduction of the number of Fy(b) antigens on the erythrocyte surface, remains a weakness of current serological blood grouping techniques...

Immune hemolytic anemia is characterized by clinical and laboratory features of hemolytic anemia with direct antiglobulin test (DAT) positivity. It could be autoimmune hemolytic anemia (AIHA), alloimmune, or drug-induced hemolysis based on the antigenic stimulus. Furthermore, based on thermal amplitude of autoantibody, AIHA is classified as warm (65%), cold (30%), and mixed (5%) type. Mixed AIHA is extremely rare in children and must be differentiated from warm AIHA with clinically insignificant cold agglutinins and cold hemagglutinin disease as their treatment is different...

The sequence information of the genomic form of the human ABO blood group orthologous gene (erythrocyte antigen A, EAA) is not complete in pigs. Therefore, we cloned and characterized the nucleotide sequence of EAA intron 7, which is critical to understand genetic difference between A and 0 blood groups in pigs, covering complete genomic sequence information of EAA excluding a ~560bp unsequencible gap. We also analyzed genetic polymorphisms within EAA intron 7 and exon 8. We found difference in A0 blood group frequencies among pig breeds...

Patients with AML may show ABO blood typing discrepancy, and the expression levels of the ABO antigens may show some alterations with the disease progression. To better understand this phenomenon, the blood samples of 25 AML patients and 25 healthy blood donors were examined. The serological ABO blood types of the patients were determined in different AML stages, and gene sequencing was performed to identify the precise ABO genotypes. Reverse transcription-polymerase chain reaction (RT-PCR) was carried out to detect the transcription levels of the antigens...

OBJECTIVE: ABO antigens are highly abundant in many human cell types, including platelets, vascular endothelium, and red blood cells. The presence of a thrombus is associated with adverse clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). We reviewed the relationship between ABO blood groups and thrombus burden in patients with STEMI. PATIENTS AND METHODS: We carried out a retrospective study of 396 patients with STEMI who did not have an ABO blood group or thrombus burden...

BACKGROUND: Blood product mistransfusions occur when a process error causes transfusion of incompatible blood products. These events are known sources of negative patient outcomes. One such event demonstrated an institutional knowledge gap and an opportunity to reduce this source of transfusion errors. The focus of this study was to evaluate the application of point of care cognitive aids to bridge potentially lethal knowledge gaps in blood product to patient compatibility. METHODS: A patient-donor ABO antigen compatibility grid for red blood cells (RBC) and fresh frozen plasma (FFP) was developed for creation of a cognitive aid and a blood product safety quiz...

Objectives: The ABO blood group antigens were found on most epithelial cells and in secretions. In the normal endometrium there is a variable expression of histo-blood group and related antigens suggesting a hormonal regulation. A relationship between ABO blood groups and endometrial cancer has been investigated with contradictory results. In this study we investigated the influence of blood types on clinical and pathological characteristics of endometrial cancer patients. Method: Retrospective cohort study...

Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is a rare subtype of lymphoma that is often associated with poor clinical prognosis. Several studies have shown that hepatitis B virus (HBV) infection may be associated with increased risk of B-cell non-Hodgkin lymphoma; however, because of the rarity of ENKTL, little is known about its association with HBV. Our study aimed to assess whether HBV infection was associated with increased odds of ENKTL. We conducted a hospital-based case-control study including 417 ENKTL cases and 488 age- and sex-matched subjects with nonmalignant diseases unrelated to HBV infection...

In the current precision medicine era, more and more samples get genotyped and sequenced. Both researchers and commercial companies expend significant time and resources to reduce the error rate. However, it has been reported that there is a sample mix-up rate of between 0.1% and 1%, not to mention the possibly higher mix-up rate during the down-stream genetic reporting processes. Even on the low end of this estimate, this translates to a significant number of mislabeled samples, especially over the projected one billion people that will be sequenced within the next decade...

Effects of blood transfusions on platelet-related and leukocyte-related inflammation are unclear. We simulated transfusion using in vitro blood mixing to evaluate platelet-leukocyte aggregations (PLA) and platelet P-selectin expression, and the mechanism of PLA. Donor packed red blood cells (pRBCs) were obtained from a blood bank. Recipient whole blood samples were obtained from patients undergoing cardiac surgery. Blood sample mixtures were divided into four groups: group M, cross-matched blood type mixing; group O, donor type O with other blood type mixing (A, B, or AB); group S, ABO type-specific uncross-matched blood mixing; and group I, ABO incompatibility mixing...

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...
