Crossmatching is performed prior to transfusion.
A system of universal human blood group isoantigens with many associated subgroups. The M and N traits are codominant and the S and s traits are probably very closely linked alleles, including the U antigen. This system is most frequently used in paternity studies.
Multiple erythrocytic antigens that comprise at least three pairs of alternates and amorphs, determined by one complex gene or possibly several genes at closely linked loci. The system is important in transfusion reactions. Its expression involves the X-chromosome.
An antigenic mismatch between donor and recipient blood. Antibodies present in the recipient's serum may be directed against antigens in the donor product. Such a mismatch may result in a transfusion reaction in which, for example, donor blood is hemolyzed. (From Saunders Dictionary & Encyclopedia of Laboratory Medicine and Technology, 1984).
A group of dominantly and independently inherited antigens associated with the ABO blood factors. They are glycolipids present in plasma and secretions that may adhere to the erythrocytes. The phenotype Le(b) is the result of the interaction of the Le gene Le(a) with the genes for the ABO blood groups.
A blood group related to the ABO, Lewis and I systems. At least five different erythrocyte antigens are possible, some very rare, others almost universal. Multiple alleles are involved in this blood group.
The major sialoglycoprotein of the human erythrocyte membrane. It consists of at least two sialoglycopeptides and is composed of 60% carbohydrate including sialic acid and 40% protein. It is involved in a number of different biological activities including the binding of MN blood groups, influenza viruses, kidney bean phytohemagglutinin, and wheat germ agglutinin.

Infantile cystinosis in France: genetics, incidence, geographic distribution. (1/1160)

A national distribution of 66 French patients, from 49 sibships, has been studied. Segregation analysis, using the maximum likelihood method, was found to agree with the theoretical values expected in recessive autosomal inheritance. The birthplaces of these patients show an unequal geographic distribution of cystinosis, the incidence being higher in Western France. Compared with the total number of live births during the period 1959 to 1972, the minimum incidence of the condition in the province of Brittany is 1 per 25 909, and the gene frequency 0.0062. In the rest of France, the minimum incidence is 1 per 326,440 and the gene frequency 0.0018. Application of Dahlberg's formula gives a similar result. The mean inbreeding coefficient is 530 X 10(-5), a figure 23 times higher than the mean coefficient of France. An indirect test of inbreeding, the distance between parental birthplaces, was studied, first using the French administrative boundaries, second by using kilometers. This distance was constantly smaller for the parents of patients than for the parents of controls. Analysis of two erythrocyte polymorphisms (ABO and Rh) showed a large excess of group A patients when compared with overall French data. These findings are difficult to interpret on genetic grounds. The genetic reasons for the unequal geographic distribution of cystinosis in France are discussed.  (+info)

Acquisition of human blood group antigens by Schistosoma mansoni. (2/1160)

Juvenile forms of Schistosoma mansoni (schistosomula) have been cultured in human blood of various specificities and tested for the presence of blood group substances on their surfaces. The tests employed were survival following transfer into rhesus monkeys immunized against human blood substances, mixed agglutination reactions, and immunofluorescence. A, B, H AND Lewisb+ antigens were expressed at the surface when the parasites were cultured in blood of appropriate specificities. Rhesus, M N S, AND Duffy antigens could not be detected on the parasite surface following culture. The evidence suggests that the expressed blood group antigens are of host origin and are acquired by the parasite during culture, probably in the form of glycolipids or megaloglycolipids. It is likely that these substances are also acquired by parasites in the bloodstream of man. They may serve to mask surface parasite antigens, and so enable schistosomes to evade parasite-specific humoral or cellular immune responses.  (+info)

H (0) blood group determinant is present on soluble human L-selectin expressed in BHK-cells. (3/1160)

In the present study we show that the H (0) blood group determinant Fuc alpha1-2Gal beta1-4GlcNAc beta1-R is present on N-linked glycans of soluble human L-selectin recombinantly expressed in baby hamster kidney (BHK) cells. The glycans were isolated using complementary HPLC techniques and characterized by a combination of exoglycosidase digestion and mass spectrometry. The linkage of the fucose residues was determined by incubation of the glycans with specific fucosidases. The H blood determinant Fuc alpha1-2Gal beta1-4GlcNAc beta1 was detected for bi-, 2,4 branched tri- and tetraantennary structures. To our knowledge, the proposed oligosaccharide structures represent a new glycosylation motif for recombinant glycoproteins expressed on BHK cells.  (+info)

Poly-N-acetyllactosamine synthesis in branched N-glycans is controlled by complemental branch specificity of I-extension enzyme and beta1,4-galactosyltransferase I. (4/1160)

Poly-N-acetyllactosamine is a unique carbohydrate that can carry various functional oligosaccharides, such as sialyl Lewis X. It has been shown that the amount of poly-N-acetyllactosamine is increased in N-glycans, when they contain Galbeta1-->4GlcNAcbeta1-->6(Galbeta1-->4GlcNAcbeta1 -->2)Manalpha1-->6 branched structure. To determine how this increased synthesis of poly-N-acetyllactosamines takes place, the branched acceptor was incubated with a mixture of i-extension enzyme (iGnT) and beta1, 4galactosyltransferase I (beta4Gal-TI). First, N-acetyllactosamine repeats were more readily added to the branched acceptor than the summation of poly-N-acetyllactosamines formed individually on each unbranched acceptor. Surprisingly, poly-N-acetyllactosamine was more efficiently formed on Galbeta1-->4GlcNAcbeta1-->2Manalpha-->R side chain than in Galbeta1-->4GlcNAcbeta1-->6Manalpha-->R, due to preferential action of iGnT on Galbeta1-->4GlcNAcbeta1-->2Manalpha-->R side chain. On the other hand, galactosylation was much more efficient on beta1,6-linked GlcNAc than beta1,2-linked GlcNAc, preferentially forming Galbeta1-->4GlcNAcbeta1-->6(GlcNAcbeta1-->2)Manalph a1-->6Manbeta -->R. Starting with this preformed acceptor, N-acetyllactosamine repeats were added almost equally to Galbeta1-->4GlcNAcbeta1-->6Manalpha-->R and Galbeta1-->4GlcNAcbeta1-->2Manalpha-->R side chains. Taken together, these results indicate that the complemental branch specificity of iGnT and beta4Gal-TI leads to efficient and equal addition of N-acetyllactosamine repeats on both side chains of GlcNAcbeta1-->6(GlcNAcbeta1-->2)Manalpha1-->6Manbet a-->R structure, which is consistent with the structures found in nature. The results also suggest that the addition of Galbeta1-->4GlcNAcbeta1-->6 side chain on Galbeta1-->4GlcNAcbeta1-->2Man-->R side chain converts the acceptor to one that is much more favorable for iGnT and beta4Gal-TI.  (+info)

A predominantly hydrophobic recognition of H-antigenic sugars by winged bean acidic lectin: a thermodynamic study. (5/1160)

The thermodynamics of binding of winged bean (Psophocarpus tetragonolobus) acidic agglutinin to the H-antigenic oligosaccharide (Fucalpha1-2Galbeta1-4GlcNAc-oMe) and its deoxy and methoxy congeners were determined by isothermal titration calorimetry. We report a relatively hydrophobically driven binding of winged bean acidic agglutinin to the congeners of the above sugar. This conclusion is arrived, from the binding parameters of the fucosyl congeners, the nature of the enthalpy-entropy compensation plots and the temperature dependence of binding enthalpies of some of the congeners. Thus, the binding site of winged bean acidic agglutinin must be quite extended to accommodate the trisaccharide, with non-polar loci that recognize the fucosyl moiety of the H-antigenic determinant.  (+info)

Normal human serum contains natural antibodies reactive with autologous ABO blood group antigens. (6/1160)

It is widely accepted that the serum of healthy individuals contains natural antibodies only against those blood group A or B antigens that are not expressed on the individual's red blood cells. The mechanisms involved in tolerance to autologous blood group antigens remain unclear. In the present study, we show that IgM and IgG antibodies reactive with autologous blood group antigens are present in the immunoglobulin fraction of normal human serum. Natural IgG anti-A antibodies purified by affinity chromatography from IgG of individuals of blood group A exhibited an affinity for A trisaccharide antigen in the micromolar range and agglutinated A red cells at sixfold higher concentrations than those required for agglutination with affinity-purified anti-A IgG of individuals of blood group B. Whereas autoantibodies reactive with self A and B antigens are readily detected in purified IgG and IgM fractions, their expression is restricted in whole serum as a result of complementary interactions between variable regions of antibodies. These observations suggest that tolerance to autologous ABO blood group antigens is dependent on peripheral control of antibody autoreactivity.  (+info)

Purification and characterization of an anti-(A+B) specific lectin from the mushroom Hygrophorus hypothejus. (7/1160)

A lectin (HHL) was isolated from the fruiting body of the mushroom Hygrophorus hypothejus by a combination of affinity chromatography on stromas of group B erythrocytes embedded in polyacrylamide gel, and DEAE-trisacryl and gel filtration chromatography. Its molecular mass, as determined by gel filtration, is estimated to be 68000 kDa and its structure is tetrameric with four identical subunits assembled with non-covalent bonds. HHL agglutinates specifically A and B blood group erythrocytes and in hemagglutination inhibition assays, exhibits sugar-binding specificity toward lactose, the anomeric alpha form being more effective than the beta form.  (+info)

Alteration of sialyl Lewis epitope expression in pterygium. (8/1160)

PURPOSE: Mucin-related antigens are abundantly expressed by the cells of the normal human conjunctiva. The pattern of these antigens in pterygium, and especially the role of Galbeta1-3GlcNAc alpha2,3-sialyltransferase (ST3Gal III), sialyltransferase necessary to build the sialyl-Le(a) (Lewis(a)) antigen, were studied. METHODS: Immunoperoxidase staining was performed on 28 pterygia using different monoclonal antibodies: anti-M1 (against the peptidic core of gastric mucins encoded by MUC 5AC gene), anti-Le(a)(7LE), anti-sialyl Le(a)(NS 19-9), and anti-Le(b)(2-25LE). A serologic Lewis determination was done in 18 patients. ST3Gal III sialyltransferase expression was also studied in 10 healthy conjunctiva and 10 pterygia by reverse transcriptase-polymerase chain reaction (RT-PCR). Glyceraldehyde-3-phosphate-dehydrogenase was used as an endogenous internal control. RESULTS: First, Le(a), sialyl Le(a), and Le(b) immunoreactivities either decreased or were no longer detectable in pterygium goblet cells as opposed to normal conjunctiva. Second, unlike in pterygium, the Lewis immunoreactivity, which is mainly located in the surface epithelial cells in the normal conjunctiva, was occasionally restricted to the epithelial cells of the deep layers. However, M1 mucins did show an identical pattern expression in a normal conjunctiva and pterygium. ST3Gal III expression was significantly lower in pterygium (0.20+/-0.02 AU [arbitrary units]) than in normal conjunctiva (0.95+/-0.12 AU). CONCLUSIONS: ST3Gal III gene is less expressed in pterygium than in normal conjunctiva. This observation could explain the decrease of sialyl Le(a) expression observed in pterygium by immunohistology.  (+info)

In the 2 large, prospective cohorts of the NHS and HPFS, we observed a significantly elevated risk of incident CHD for participants with blood group A or B or AB, compared with those with blood group O. The highest risk was observed for blood group AB, followed by blood groups B and A. The association between ABO blood group and CHD risk was not significantly modified by other known risk factors for CHD, including age, sex, alcohol consumption, smoking, physical activity, or diabetes mellitus history. In total, 6.27% of CHD cases were attributable to a non-O blood group (A, B, or AB blood types). A meta-analysis of 6 prospective studies indicated that non-O blood group was associated with an 11% increased risk of CHD compared with O blood group.. Associations between ABO blood groups and CHD have been investigated for several decades. However, the results have been conflicting, especially for the prospective cohort studies. Recently a meta-analysis reported that individuals with non-O blood ...
Background Previous studies have examined the association between ABO blood group and the risk of some malignancies. However, no prospective cohort study to date has examined the association between ABO blood group and the risk of skin cancer. Methodology/Principal Findings Using two large cohorts in the US, we examined ABO blood type and incidence of skin cancer, including melanoma, squamous cell carcinoma (SCC), and basal cell carcinoma (BCC). We followed up study participants (70,650 female nurses and 24,820 male health professionals) on their diagnosis of incident skin cancer from cohort baseline (1976 in women and 1986 in men) until 2006. Study participants reported their blood type in 1996 in both cohorts. During the follow-up, 685 participants developed melanoma, 1,533 developed SCC and 19,860 developed BCC. We used Cox proportional hazards models to calculate the hazard ratios (HR) and 95% confidence intervals (CI) of each type of skin cancer. We observed that non-O blood group (A, AB, and B

Helicobacter pylori infection is a high prevalence infection worldwide, and it is more common in developing countries than developed ones (Magalhães and Luzza, 2006). It is a major risk factor for chronic gastritis, peptic ulcer and gastric cancer (Fock and Ang, 2010). The ABO blood group system is the most important in human blood transfusion. The blood group antigens present on RBC are permanent, fixed and lifelong biological markers of any individual, they are almost as individual as fingerprints (Ravn and Dabelstein, 2000). The distribution of the ABO blood groups varies in populations throughout the world (Garratty et al., 2004). In addition to clinical significance for transfusion and transplantation, it is becoming increasingly apparent that ABO antigens are of biological significance and may be associated with predisposition to, or protection from many diseases (Reid and Bird, 1990).. Many authors reported an association between blood group O and H. pylori infection (Kanbay, et al., ...
In the process of ABO-incompatible (ABOi) organ transplantation, removal of anti-A and/or B antibodies from blood plasma is a promising method to overcome hyperacute rejection and allograft loss caused by the immune response between anti-A and/or B antibodies and the A and/or B antigens in the recipient. Although there are commercial columns to do this work, the application is still limited because of the high production cost. In this study, the PglB glycosylation pathway from Campylobacter jejuni was exploited to produce glycoprotein conjugated with Escherichia coli O86:B7 O-antigen, which bears the blood group B antigen epitope to absorb blood group B antibody in blood. The titers of blood group B antibody were reduced to a safe level without changing the clotting function of plasma after glycoprotein absorption of B antibodies in the plasma. We developed a feasible strategy for the specific adsorption/removal of blood group antibodies. This method will be useful in ABOi organ transplantation and
Background: Non-O blood type is associated with higher procoagulant proteins and potentially stroke. Prior studies may overestimate the association due to lack of control for race and stroke risk factors as there are known racial differences in blood type, conventional stroke risk factors, and stroke risk.. Methods: REGARDS recruited 30,239 participants in their homes between 2003-07 from the continental US; 55% were female, 41% were black, and 56% lived in the southeast (by design). Using a case-cohort design, 553 participants with incident stroke and 991 participants without baseline stroke were genotyped to determine blood type. Cox proportional hazard models adjusting for race and Framingham or ARIC stroke risk factors were used to determine the association of blood type with incident stroke.. Results: Blacks had a higher frequency of blood type B (17% vs. 10%) and AB (5% vs. 2%) and a lower frequency of blood type O (31% vs. 42%) than whites (p ,0.001) (Table). Except for diabetes (OR 4.1 ...
ABO blood group phenotype is determined by the expression of specific antigens on red blood cells, endothelial cells, platelets, and many other cells and tissues. The presence of A or B antigen results in the expression of A, B, or AB phenotype, whereas the lack of both A and B antigen results in the expression of the O phenotype. These ABH antigens comprise complex terminal carbohydrate molecules on glycoproteins and glycolipids, generated by the addition of N-acetylgalactosamine (A antigen) or d-galactose (B antigen) to existing N-glycan and O-glycan structures through the action of the ABO glycosyltransferases.7 The A and B alleles of the ABO locus encode A and B glycosyltransferases, which in turn catalyze the transfer of the different carbohydrates onto a common core H antigen, to form an A or B antigen. However, type O individuals only express H antigen because the O isoform of ABO lacks glycosyltransferase activity.8. In the past, studies have associated ABO blood groups with CVD, whereby ...

BackgroundThe ABO blood group system is clinically important in kidney transplantation, but ABO genotyping fails to attract sufficient attention in some countries and regions. We identified one case of early graft dysfunction due to an ABO genotype mismatch. Here, we performed ABO genotyping in blood samples, analyzed grouping discrepancies, and investigated the weak A subgroup frequency in kidney transplantation candidates.MethodsBlood samples from 302 uremic patients with grouping discrepancies and 356 uremic patients with type A blood were analyzed using standard serologic serotyping techniques. The ABO genotypes and alleles were analyzed by polymerase chain reaction sequence-specific primer (PCR-SSP) and sequence-based typing (PCR-SBT).ResultsAll 302 uremic patients with grouping discrepancies carried weak ABO subgroup alleles and 77.48% carried irregular ABO antibodies. The discrepancy rate between serotyping and genotyping was 42.38%, and the mismatching rate of donor selection according to
It is well known that ABO blood group system incompatible kidney transplantation (ABOi-KT) is an effective strategy for end-stage renal disease. The main barrier for ABOi-KT is how to keep host B cell activation and blood group antibody titer in low levels. Moreover, the mechanism of B cell activation induced by blood group antigen was unclear in ABOi-KT. In this study, HK2 cells were identified to express blood group B antigen when cocultured with lymphocytes of blood group A. Optical microscope observation demonstrated that HK2 cells in coculture group gradually decreased. Furthermore, flow cytometer assay identified that T cell phenotypes (CD3+, CD3+CD4+ and CD3+CD8+) had no significant change and B cell phenotypes (CD19+ and CD138+) were all significantly enhanced (3.07 and 3.02 folds) at day 4. In addition, immunoturbidimetry analysis demonstrated that blood group B antibody was significantly increased to 2.35 fold at day 4, IgG was significantly increased to 3.60 and 2.81 folds at days 4 and 8
This study investigated the relationship between ABO blood groups and Rh antigens and rates of CRC, which involves numerous etiological factors. Our results show that the prevalence of blood groups A and B, as well as Rh antigen positivity were significantly higher among CRC patients. Despite being an archive study, it was of a retrospective design, which is a drawback in terms of the strength of the evidence. ABO blood group antigens were discovered by Karl Landsteiner in 1901 and Rh antigens by Huang et al.2 in 1940. The ABO blood group antigens are encoded on chromosome 9q34. Although these antigens are biochemical components of the erythrocyte membrane, they have also been identified in epithelial cells of the gastrointestinal mucosa.6 There is an intriguing hypothesis regarding the pathophysiological link between ABO blood groups and malignancy.

On analysis of 15,523 kidney transplant recipients, blood group O was not associated with patient survival (hazard ratio (HR) 0.96, 95% confidence interval (CI) 0.89-1.04) nor death censored graft survival (HR 0.97, 95% CI 0.89-1.05) compared to non-blood group O recipients. Competing risks analyses showed an increased risk of cancer-related mortality in blood group O recipients on univariate analyses (HR 1.18, 95% CI 1.01-1.37) however, this became insignificant on multivariate analyses. On secondary analyses, recipient blood group AB (4.11% participants) was associated with inferior death censored graft survival compared to those with blood group O (HR 1.24, 95% CI 1.02-1.50). Although recipient ABO blood groups were not associated with patient nor graft survival, differences in cause-specific mortality between individual blood groups cannot be excluded based on current analyses ...

|p|Although the precise biological role of lysosomal membrane-associated glycoproteins (LAMPs) and ABH histo-blood group antigens (HBGAs) remains somewhat unclear, they are thought to be related to cell differentiation, cellular adhesion, and tumorigenesis. Here, we present the first comparative immunohistochemical study of both LAMPs and HBGAs in normal and neoplastic skin. Their localization is compared to that of high molecular weight cytokeratin and cytokeratin MNF 116. LAMPs and HBGA were differentially expressed in the normal stratified squamous epithelium, suggesting that they are involved in the initial steps of the differentiation process, whereas HBGAs are characteristic of terminal keratinocyte differentiation. No change in the reactivity for HBGA was detected in the stratified epithelium overlying squamous cell or basal cell carcinomas, whereas a considerable loss of LAMPs was detected. LAMPs were overexpressed in tumor cells, whereas HBGAs were lost in tumor zones of
Objective-Epidemiological data regarding the association between ABO blood groups and risk of coronary heart disease (CHD) have been inconsistent. We sought to investigate the associations between ABO blood group and CHD risk in prospective cohort studies.Methods and Results-Two large, prospective cohort studies (the Nurses Health Study [NHS] including 62 073 women and the Health Professionals Follow-up Study [HPFS] including 27 428 men) were conducted with more than 20 years of follow-up (26 years in NHS and 24 years in HPFS). A meta-analysis was performed to summarize the associations from the present study and previous studies. In NHS, during 1 567 144 person-years of follow-up, 2055 participants developed CHD; in HPFS, 2015 participants developed CHD during 517 312 person-years of follow-up. ABO blood group was significantly associated with the risk of developing CHD in both women and men (log-rank test; P=0.0048 and 0.0002, respectively). In the combined analysis adjusted for ...

Genetic variations in ABO define the ABO blood group system [MIM:616093]. The ABO blood group system is the most important blood group system in blood transfusion. The sequence shown here is that of the A transferase. The B form differs by a few residues substitution. Residues 266 and 268 are important for specificity. The reference genome assembly (GRCh38/hg38) describes a non-functional O-type ABO allele. The O-type ABO allele results in a guanine deletion (NM_020469.2: c.286delG). This deletion induces a frameshift and creates a premature stop codon resulting in a truncated (117 amino acids) protein deprived of any glycosyltransferase activity (PubMed:2333095 ...
Humans owe a lot to the Rhesus macaque.. This little monkey has provided insights into space travel, cloning and human behaviour. But perhaps most importantly it first alerted scientists to the existence of the famous Rh factor in human blood, a molecule that is either present (Rh+) or absent (Rh-) on our red blood cells, says Dr Bruce Rideout from San Diego Zoos Institute for Conservation Research.. The Rh stands for the rhesus monkey because researchers recognised that this human blood antigen was similar to a rhesus monkey blood antigen. Blood types have only been studied in a handful of primate species, but Rideout says Old World monkeys and apes have been shown to have blood types comparable, although not identical, to the human ABO blood group system.. According to the Australian Red Cross there are more than 270 human blood antigens, belonging to over 30 blood group systems. The two major blood group systems used in transfusions are the Rhesus factor and the ABO blood group ...

As ABH substances are expressed on tissues and secreted in body fluids, they could drive an immune response in minor ABO-incompatible HSCT. The aim of the study was to investigate the prognostic role of the recipients ABH secretor status.; Patients who underwent minor ABO-incompatible HSCT were included. Secretor status was determined either serologically or by molecular genetics.; Between March 1996 and June 2012, a total of 176 patients received minor ABO-incompatible HSCT and 150 (85%) were secretors. Incidence and severity of acute graft-versus-host disease (GVHD) and chronic GVHD did not differ between secretors and nonsecretors (cumulative incidences ± standard errors: acute GVHD on Day 100, 41 ± 11 and 46 ± 5%, p = 0.59; chronic GVHD at 2 years, 52 ± 13 and 56 ± 5%, p = 0.62, for secretors and nonsecretors, respectively). Additionally, nonrelapse mortality (NRM) and overall ...
The relationship of the ABO blood groups to various diseases has received increasing attention of late. Thus, Aird et al.1 report that the frequency of blood group A is greater and the frequency of blood group O less in patients suffering from cancer of the stomach than in the general population of the locality in which they live. Blood group O has been reported to be strikingly high, and the other three blood groups increasingly low, in patients suffering from peptic ulcer.2 Studies have revealed an inverse relationship between the frequencies of blood groups O and A in patients with ...
Background ABO blood group-incompatible (ABOi) kidney transplantation is considered a safe procedure, with non-inferior outcomes in large cohort studies. Its contribution to living kidney transplantation programs is substantial and growing. The objective of this meta-analysis was to systematically investigate outcomes in ABO-incompatible kidney transplant recipients compared to center-matched ABO blood group-compatible (ABOc) control patients.. Methods Comprehensive searches were conducted in Embase, Medline, Cochrane, Web-of-Science and Google Scholar. MOOSE study guidelines for observational studies and Newcastle Ottawa bias scale were implemented to assess studies. Meta-analysis was performed using Review Manager 5.3. A subgroup analysis on antibody removal technique was performed.. Results After identifying 2728 studies addressing ABOi kidney transplantation, 26 studies were included, describing 1346 unique ABOi patients and 4943 ABOc controls. Baseline patient characteristics revealed no ...
The mucus layer covering the human intestinal epithelium forms a dynamic surface for host-microbial interactions. In addition to the environmental factors affecting the intestinal equilibrium, such as diet, it is well established that the microbiota composition is individually driven, but the host factors determining the composition have remained unresolved. In this study, we show that ABO blood group is involved in differences in relative proportion and overall profiles of intestinal microbiota. Specifically, the microbiota from the individuals harbouring the B antigen (secretor B and AB) differed from the non-B antigen groups and also showed higher diversity of the Eubacterium rectale-Clostridium coccoides (EREC) and Clostridium leptum (CLEPT) -groups in comparison with other blood groups. Our novel finding indicates that the ABO blood group is one of the genetically determined host factors modulating the composition of the human intestinal microbiota, thus enabling new applications in the field of
The prevalence of malaria among 250 pregnant women attending antenatal clinic in Agbonchia Health Centre Eleme, Rivers State, Nigeria was investigated using thick and thin blood film stained with Giemsa. The stained slides were examined microscopically for malaria parasites. The prevalence of malaria among the pregnant women was 40.6% and the prevalence among 50 non-pregnant women used as control was 16.0%. The prevalence of malaria by age group among the pregnant women was 36.1-46.8% from age 20-40yrs. The prevalence of malaria by haemoglobin genotype are HbAA 42.4% and HbAS 34.6%, statistically at p,0.05 there is no significant difference in the prevalence of malaria between HbAA and HbAS, but there is significant difference in the prevalence of severe malaria between HbAA and HbAS. The prevalence of malaria among ABO blood groups showed that blood group O had the highest prevalence 44.4% but minimal episode of severe malaria compared with the other blood groups. Blood group O and HbAS ...

A blood type (also called a blood group) is a classification of blood based on the presence or absence of inherited antigenic substances on the surface of red blood cells (RBCs). These antigens may be proteins, carbohydrates, glycoproteins or glycolipids, depending on the blood group system, and some of these antigens are also present on the surface of other types of cells of various tissues. Several of these red blood cell surface antigens, that stem from one allele (or very closely linked genes), collectively form a blood group system. Immunological effects of mismatched blood transfusions are much more likely to involve components of the ABO blood group system or the RhD antigen (also known as the Rhesus factor or Rhesus D antigen) of the Rhesus blood group system than components of any of the other blood group systems; hence, in the routine preparation of blood for transfusion in a blood bank, the presence or absence the immunogenic blood group antigens, the A antigen, the B antigen and the ...

血液型不適合妊娠とは・・・. There are many different blood types besides ABO blood type and Rh blood type. The blood type of the fetus is not always the same of the mothers because its genetic information is inherited from both the fetuss mother and father.. * ABO blood type: Different blood types between the mother and the fetus cause very few problems.. * Rh blood type: If the mother is Rh-negative and the fetus is Rh-positive, her body will develop anti-D antibody, which attacks fetal blood when it crosses the placental barrier during pregnancy or at delivery. Once the anti-D antibody is produced, the fetal red blood cells will be destroyed and the fetus may develop problems such as severe anemia, fetal edema and severe jaundice (icterus gravis).. * Irregular antibody positive: The fetus may be affected the same way as Rh incompatibility in pregnancy.. * About 0.5% of Japanese women are Rh negative.. * About 2-3% of pregnant women are irregular antibody positive.. ...
The blood-type diet was popularized in the book Eat Right for Your Type, written by naturopath Peter DAdamo. The theory behind the diet is that the ABO blood type should match the dietary habits of our ancestors and people with different blood types process food differently. According to the theory, individuals adhering to a diet specific to ones blood type can improve health and decrease risk of chronic illness such as cardiovascular disease. The book was a New York Times best-seller that has been translated into 52 languages and sold over 7 million copies. The U of T researchers took an existing population of mostly young and healthy adults who provided detailed information about their usual diets and provided fasting blood that was used to isolate DNA to determine their ABO blood type and the level of cardiometabolic risk factors, such as insulin, cholesterol and triglycerides. Diet scores were calculated based on the food items listed in Eat Right for Your Type to determine relative ...

Blood group O was associated with an increased prevalence of active placental infection in primiparae and with a reduced risk of placental malaria in multiparae. Placental parasitaemia occurs at least twice as frequently in primiparae but only among blood group O women. This effect of parity, that is one of the cardinal features of placental malaria, was not observed in non-O phenotypes for any of the placental malaria histological types.. In multiparae and specifically in mothers with past or non-infected placentae blood group O was also associated with higher mean feto-placental weight ratios compared to non-O individuals. These differences associated with multiparity can be interpreted to represent a parity-specific association of the blood group O phenotype with the protective malarial immunity which occurs in multigravidae [3]. Mean birth weight was also significantly increased in babies of primiparae with the O phenotype, suggesting that despite the greater susceptibility of primigravidae ...

Background The Blood-Type diet advises individuals to eat according to their ABO blood group to improve their health and decrease risk of chronic diseases such as cardiovascular disease. However, the association between blood type-based dietary patterns and health outcomes has not been examined. The objective of this study was to determine the association between blood-type diets and biomarkers of cardiometabolic health and whether an individuals ABO genotype modifies any associations. Methods Subjects (n = 1,455) were participants of the Toronto Nutrigenomics and Health study. Dietary intake was assessed using a one-month, 196-item food frequency questionnaire and a diet score was calculated to determine relative adherence to each of the four Blood-Type diets. ABO blood group was determined by genotyping rs8176719 and rs8176746 in the ABO gene. ANCOVA, with age, sex, ethnicity, and energy intake as covariates, was used to compare cardiometabolic biomarkers across tertiles of each Blood-Type
ABO blood group rs8176719 represents a site in the ABO gene, often referred to as either c.261delG or, less commonly, c.260_262insG, and it is a key SNP in determining blood group type O status. [PMID 2333095] An allele that encodes either a blood group type A or type B will have a (G) at this SNP site, i.e. such an allele will be rs8176719(G). If a one-base deletion has occured at this site, removing this nucleotide all together, the corresponding allele is considered to be rs8176719(-) and encodes the most common blood group type O allele. However, an individual will typically only be blood group type O if they are carry two copies of (are homozygous) for this deletion, in other words, if their genotype is rs8176719(-;-). If they carry one copy, they could be blood type A, or blood type B (but are unlikely to be type O). A person who is rs8176719(G;G) is likely to be of blood type A, B, or AB, but due to the existence of (rare) nonfunctional O alleles brought about by (nondeletional) mutations ...

Background & Objectives: The various ABO and Rh blood groups with different distribution frequencies in the general population have been found to be associated with different diseases, most notably gastritis. Many studies have claimed Rh groups to be indifferent to such association. Nonetheless, ABO group is found to linked with chronic gastritis. The aim of this study was to estimate the frequencies of ABO and Rh blood groups and the gastritis amongst the first and second year undergraduate medical and dental students; and to study their relationships.. Materials & Methods: In a descriptive, cross-sectional study, 247 study participants were enrolled. After procuring clearance from the institutional review committee and the informed and written consent from the study participants, data collection was done on the variables, year of study (first or second year), gender, blood groups (ABO and Rh) and history of gastritis (present or absent).. Results: Blood group O was the commonest (n=99; 40.1%) ...
ABO-incompatible (ABO-i) kidney transplantation (KT) has emerged for overcoming the shortage of organ donors. Although this technique initially achieved only low graft survival due to isoagglutinin, recently developed desensitization protocols have improved survival to levels that are comparable to ABO-compatible KT. However, isoagglutinin is still regarded as a major obstacle to ABO-i KT. In this study, we evaluate the impact of isoagglutinin titer on clinical outcomes as well as factors that may influence isoagglutinin titers. In total, data from 95 patients who underwent ABO-i KT were analyzed. Preoperatively, rituximab administration and plasmapheresis were performed until the titer was reduced to ≤1:4. Retrospective analysis included blood group; timing and dosage of rituximab; isoagglutinin titer; number of plasmapheresis; and clinical outcomes including graft survival and serum creatinine. Graft survival was 95.8% (n = 91) and average serum creatinine at 1- and 1.5-year post-ABOi-KT was ...

Hemoglobin variants, ABO and Rhesus blood groups vary from one population to another. The study was designed to sample pregnant women population from Ayetoro community of Ogun state, Nigeria, for the purpose of updating information on the prevalence of abnormal hemoglobin variants, ABO and Rh blood groups and compare the results with previously published data. Hospital records of recruited pregnant women were sorted out for the determination of the prevalence of hemoglobin variants, ABO and Rh blood groups. Blood group O were the most prevalent (59.1%) followed by groups A (19.1%), B (17.1%) and AB (4.8%). Rhesus D antigen was positive in 97.1% and negative in 2.9% of the study population. Four genotypes; HbAA (70.5%), HbAS (18.1%), HbAC (10.5%) and HbCC (1.0%) were reported in this study. The occurrence of the hemoglobin variants and the different ABO blood groups varied significantly (p
Pseudomonas aeruginosa lectins interact with Escherichia coli strains O86B7 and O128B12, which possess B and H (O) blood group determinants, respectively. The interaction could be demonstrated by specific agglutination of the bacteria, by haemagglutination inhibition tests and by lectin-mediated peroxidase binding to the bacteria. The agglutination of E. coli O86B7 by the Pseudomonas galactose-binding lectin was inhibited by d-galactose and by the lipopolysaccharide extracted from E. coli O86B7. Similarly, the specific agglutination of E. coli O128B12 by the Pseudomonas mannose-binding lectin (which also binds l-fucose, l-galactose and d-fructose) was inhibited by d-mannose, l-fucose, l-galactose and d-fructose, as well as by the lipopolysaccharide extracted from E. coli O128B12. The interaction between E. coli O128B12 and the Pseudomonas mannose-binding lectin was also demonstrated by lectin-mediated peroxidase binding to the bacterial surface. Peroxidase binding was also inhibited by the above
Background: Human genetic factors such as blood group antigens may affect the severity of infectious diseases. Presence of specific ABO and Lewis blood group antigens has been shown previously to be associated with the risk of different enteric infections. The aim of this study was to determine the relationship of the Lewis blood group antigens with susceptibility to cholera, as well as severity of disease and immune responses to infection. Methodology: We determined Lewis and ABO blood groups of a cohort of patients infected by Vibrio cholerae O1, their household contacts, and healthy controls, and analyzed the risk of symptomatic infection, severity of disease if infected and immune response following infection. Principal Findings: We found that more individuals with cholera expressed the Le(a+b−) phenotype than the asymptomatic household contacts (OR 1.91, 95% CI 1.03-3.56) or healthy controls (OR 1.90, 95% CI 1.13-3.21), as has been seen previously for the risk of symptomatic ETEC ...
Abstract:. Blood groups are genetically determined and exhibit polymorphism where different population groups have significant difference in the frequency of each blood group. ABO blood group system and Rh blood group system both are most important for blood transfusion purposes. This study was conducted to determine the frequency of ABO and Rh blood groups in a tertiary care teaching hospital at Hyderabad. Retrospective study was conducted at blood bank and for a period of 4 years from June 2009 to May2013. Total 15,740 donors were tested by commercially available standard monoclonal antisera by slide and tube agglutination technique. Out of 15,740 donors; 15,384 (97.73%) were males and 356(2.27%) were females. The commonest blood group was O, followed by B, A, AB groups. In Rhesus grouping 15,012(95.37%) donors were Rh positive and 728(4.63%) donors were Rh negative. Majority of donors were in the age group of 21 to 40 years. The study has a significant implication in the effective management ...

ABO-incompatible kidney transplantation has been successfully utilised in a deceased donor and living donor kidney transplantation to improve organ utilisation and decrease waiting times. We describe a case of a successful, unanticipated ABO-incompatible donation after cardiac death (DCD) kidney transplant in a patient who had a previous ABOi haematopoietic stem cell transplant (HSCT) and had reverted to his original blood group B, after matching as a blood group A recipient with a blood group A donor. The recipient was unsensitized with a cPRA which was 0% and no donor-specific antibodies and zero HLA mismatch. An urgent anti-A titre was 1 : 2. Given the low antibody titres, we proceeded to transplantation. The patient developed delayed graft function and required dialysis on postoperative day 1 and day 2. The creatinine fell spontaneously on day 5, with progressively increased urine output and stable graft function on discharge at day 6. Anti-A titres were 1 : 1 on

ABO and Rhesus blood group data have been examined for 1,680 patients treated for gastric cancer in four London hospitals. The risk of developing gastric cancer was estimated to be 16% higher for group A subjects than for group O subjects, in close agreement with many previous reports throughout the world. More detailed analysis failed to support the suggestion that there was any special correlation between either ABO or Rhesus blood groups and the site of origin of the tumour within the stomach or the sex or age of the patient. Male predominance among the patients was noted to be greater at ages 40-69 years than at other ages and greater for tumours of the upper two thirds of the stomach than for tumours that arose distally.

Next to ABO blood group system. Rhesus (Rh) system is the most important blood group system. Rh system was demonstrated by Landsteiner and Weiver in 1940. Their experiment was to produce antibody to the RBCs of Rhesus monkey in the rabbits and guinea pigs. They found that the antibodies to the RBCs of Rhesus monkey also agglutinated the RBCs of 85 percent human population. If an individuals RBCs were agglutinated by the antiserum of Rhesus monkey RBCs, the individual was said to have the Rhesus factor in his RBCs (i.e. Rh positive). If an individuals RBCs werent agglutinated by the antiserum of Rhesus monkey RBCs, the individual lacked the Rh factor (i.e. Rh negative). Now it is known that the Rh system is complex and our present understanding is based on Fisher system. The Rh antigens are found on a 30 to 32 kDa RBC membrane protein. The Rh antigen has not been found to have any definite function. There are about 40 different antigens in the Rh system. Of them, five antigenic determinants ...

Purpose: Plasmapheresis in combination with immunoglobulin and rituximab is often used to induce accommodation in ABO-incompatible (ABOi) living-donor transplantation; however, this regimen cannot be applied to cases of ABOi deceased-donor transplantation. Here, we investigated whether an anti-complement component 5 (C5) antibody-based regimen can induce accommodation in ABOi heart transplantation.. *Methods: Sensitization using human blood type A antigen, induced both IgM and IgG anti-A antibodies in wild-type mice. Heterotrophic ABOi heart transplantation was performed from human blood type A-transgenic C57BL/6J mice to sensitized syngeneic wild-type C57BL/6J or allogeneic DBA/2 mice.. *Results: Both anti-C5 antibody and triple immunosuppressants (corticosteroid, tacrolimus, mycophenolate mofetil) suppressed antibody-mediated rejection, immune cell infiltration, and deposition of IgG and C4d in ABOi heart syngrafts. Allogeneic ABOi heart transplantation induced ABMR to greater degree than ...
Anniversary of Karl Landsteiner, the Nobel Prize winner for the discovery of ABO Blood group system, is celebrated as the World Blood Donor Day every year.
We describe here the development of tools to specifically extract and dissect 43 blood group-related genes from 2504 individuals and to match them with the current set of blood group variants as defined by ISBT, the official body responsible for blood group nomenclature used for clinical and scientific reporting worldwide. To our knowledge, this study reports the first in-depth analysis of all 36 blood group systems in such a large and ethnically diverse NGS dataset. Blood group prediction based on NGS has been on the horizon for several years now, but interest was further sparked by introduction of this technology into tissue typing laboratories.18 Earlier this year, NGS-based blood group and platelet phenotype predictions were reported for a single individual in a proof-of-principle study.20 All blood group systems except XG were assessed, and ,200 antigens were predicted, 17 of which were serologically confirmed.. In total, 90.1% of all alleles from 1000G could be matched with already known ...

Even though the International Society of Blood Transfusion has defined 38 blood group systems, only ABO and RhD are matched while selecting a compatible unit for blood recipients of Indian origin. Genetic disparity between a donor and a patient with reference to minor blood group antigens creates the risk of alloimmunization. The presence of red blood cell alloantibodies further creates the potential for serologic incompatibility, makes the selection of appropriate units for future transfusion more difficult, delays blood transfusion, and presents the risk of hemolytic disease of the newborn. Hence, there is a need to carry out extended blood group typing for antigens of clinical importance among donors and patients so that prophylactic antigen-matched blood can be given to a patient. Provision of antigen-matched blood will help in management of alloimmunized transfused-dependent patients carrying alloantibodies and/or autoantibodies. Typing of blood group antigens among large number of donors ...

HLA typing, along with ABO (blood type) grouping, is used to provide evidence of tissue compatibility. The HLA antigens expressed on the surface of the lymphocytes of the recipient are matched against those from various donors. Human leukocyte antigen typing is performed for kidney, bone marrow, liver, pancreas, and heart transplants. The probability that a transplant will be successful increases with the number of identical HLA antigens. Graft rejection occurs when the immune cells (T-lymphocytes) of the recipient recognize specific HLA antigens on the donors organ as foreign. The T-lymphocytes initiate a cellular immune response that result in graft rejection. Alternatively, T-lymphocytes present in the grafted tissue may recognize the host tissues as foreign and produce a cell-mediated immune response against the recipient. This is called graft versus host disease (GVHD), and it can lead to life-threatening systemic damage in the recipient. Human leukocyte antigen testing is performed to ...
ABO blood groups divide blood into 4 groups: A, B, AB, O. The other main grouping is the Rhesus system, which is either negative or positive.
ABO compatibility of red cells is recognized as fundamental to a safe transfusion. Transfusion of red cells bearing A or B antigen that is regarded as foreign by the recipient invites a prompt, dangerous and potentially fatal hemolytic reaction because everyone has pre-existing antibodies in the ABO system to antigens lacking on their own red cells. When clinical circumstances do not allow time for determination of the patients ABO group, the only safe course of action is to select Group O red cells (which are considered universal donor for the ABO type) until the ABO type can be determined - this usually takes only 5-10 minutes.. The Rh system is immunologically different. An Rh negative person will be at risk for having a hemolytic reaction only if they have been previously transfused with Rh positive blood or previously pregnant with Rh positive baby. If never exposed, an Rh negative person does not have this risk. Although the Rh (D) antigen and several other minor antigens are ...

Incompatible, yet needed: What are incompatible kidney transplants? And why are they done? The human body is primed to identify and destroy invaders like viruses, bacteria and other pathogens that can bring illness or death. Cells of the immune system and the antibodies they make recognize such foreign bodies and act to remove and destroy them. This defense system is a potential problem for kidney transplants. People have different blood groups and different human leukocyte antigens that can provoke an attack if a tissue, such as a kidney, or blood is transferred from one person to another. These two barriers are called blood group incompatibility and tissue (or histo-) incompatibility. A kidney transplant team uses the histocompatibility and blood bank testing laboratories to determine whether the tissues and blood group of a volunteer living kidney donor and the intended recipient match. A match is good, but matches are not always possible.. ...

SCIENCE DAILY) You probably know your blood type: A, B, AB or O. You may even know if youre Rhesus positive or negative. But how about the Langereis blood type? Or the Junior blood type? Positive or negative? Most people have never even heard of these.. Yet this knowledge could be a matter of life and death, says University of Vermont biologist Bryan Ballif.. While blood transfusion problems due to Langereis and Junior blood types are rare worldwide, several ethnic populations are at risk, Ballif notes. More than 50,000 Japanese are thought to be Junior negative and may encounter blood transfusion problems or mother-fetus incompatibility, he writes.. But the molecular basis of these two blood types has remained a mystery - until now.. In the February issue of Nature Genetics, Ballif and his colleagues report on their discovery of two proteins on red blood cells responsible for these lesser-known blood types.. Ballif identified the two molecules as specialized transport proteins named ABCB6 ...

Primers used for PCR are listed in Table 1. The genotyping approach for this study was used previously in several studies [17, 18]. Four separate PCR reactions were performed using different sets of primers in each sample. Each 20 µL reaction contained 2 µL DNA mixed with 1 µL of each allele-specific primer (10 pmol), 10 µL master mix (2X), and 7 µL nuclease free water. PCR was performed in a thermal cycler (Applied Biosystems, Wilmington, DE, USA). The cycling conditions followed an initial denaturation at 95℃ for 3 min, followed by 35 cycles of denaturation at 95℃ for 40 s, annealing at 56℃ for 40 s, and elongation at 72℃ for 40 s, followed with a final elongation at 72℃ for 5 min. PCR products were separated by electrophoresis on 3% agarose gels containing ethidium bromide at 40 mV for 20 min followed by 70 mV for 30-40 min. A 100 base pair (bp) DNA ladder was used as a molecular marker (Invitrogen, Wilmington, DE, USA). The gel was visualized using a G-BOX UV transilluminator ...

The intercellular pattern of fluorescence was demonstrated in 24 of 75 patients with diseases other than pemphigus and when the anti-B isohemagglutinin titer was reduced or abolished, after absorption with B substance, the inter cellular pattern was reduced considerably or abolished. The intercellular pattern of fluorescence was demonstrated in 24 of 75 patients with diseases other than pemphigus. A relationship was found between the presence of anti-B isohemagglutinins and intercellular fluorescence as demonstrated by the indirect immunofluorescent (IIF) technique, using fetal rhesus monkey ( Macaca mulatta ) esophagus as the substrate. When the anti-B isohemagglutinin titer was reduced or abolished, after absorption with B substance, the intercellular pattern was reduced considerably or abolished. The importance of the blood type of the substrate employed in the IIF technique and the blood type of the patient is stressed so that these factors which may give rise to error in the interpretation of
This case control study demonstrates that hereditary factors, especially familial history of cancer and possession of blood group O, are associated with the development of gastric cancer under the age of fifty. To our knowledge, this may be the first study showing a correlation between blood group O and the development of gastric cancer in a specific category of patients.. Risk factors for gastric cancers have been explored in a number of previous studies, including genetic factors such as blood group. Haenszel et al. suggested an association between gastric cancer and blood type A, supporting the view that genetic factors have a role in the development of gastric cancer [21]. Our study emphasizes the role of genetic factors in one subcategory of patients, those who develop gastric cancer under the age of fifty. Blood group A is more strongly associated with the diffuse histopathological type of gastric cancer than the intestinal type [21, 22]. In our study, most of the patients had a diffuse ...
