    Discrepancies in blood typing is one of the major reasons in eliciting a transfusion reaction. These discrepancies can be avoided through detailed analysis for the blood typing. Here, we report a subgroup of blood group type-B in the ABO system. Donor's blood was analyzed by employing commercial antisera for blood grouping. The results of forward (known antisera) and reverse (known antigen) reaction were not complimentary. A detailed analysis using the standard protocols by American Association of Blood Banking revealed the blood type as a variant of blood group-B instead of blood group-O. This is suggestive of the fact that blood group typing should be performed with extreme care and any divergence, if identified, should be properly resolved to avoid transfusion reactions. Moreover, a major study to determine the blood group variants in Pakistani population is needed. (author)

    Various genetic and environmental risk factors have been shown to be associated with the incidence of rheumatic diseases. However, the pathogenesis of rheumatic diseases poorly understood. Several studies have shown associations of ABO blood groups with various diseases. Our study aimed to determine whether there is an association between the types of rheumatic diseases and ABO and Rh blood groups. The study included the patients, followed up at the Immunology-Rheumatology clinic between January 2016 and December 2016 for diagnosis of rheumatic disease, who had an ABO Rh blood data. Age, gender, type of rheumatic disease, ABO Rh blood groups were recorded. When 823 patients were assessed for blood types, 42.5% patients had A type, 33.2% had O type, 15.4% had B type, and 8.9% had AB type. There was significant difference in the distribution of blood types in rheumatic diseases. While SpA, vasculitis, UCTD, Behçet's and RA were more common in the patients with A blood type; FMF, SLE, SSc and SjS were more common in the patients with O blood type. In addition, the blood type where all the diseases are observed the least commonly was AB. There was significant difference in the distribution of Rh factor in rheumatic diseases. 92.2% patients were Rh positive and 7.8% patients were Rh negative. In our study, we thought that the higher incidence of different rheumatic diseases in different blood types was associated with different genetic predisposition.

    Background: There are differences in the distribution of ABO, sub group A BO and Rh(D) blood groups in different populations of the world. Relatively little information is available about blood group distributions in Sudanese population. To see the frequency of ABO, subgroup ABO and Rh(D) blood groups in major Sudanese ethnic groups(Danagla Shaygia and Gaaleen). Blood testing for ABO, subgroup ABO and Rh(D) typing was done over six months, in 300 unrelated individuals, from both genders. Blood samples were collected from students of the college of medical laboratory science - Sudan University of Science and Technology using finger prick method and following routine slide method. Blood group 'O' was the most predominant ( 52.7%) in both Rh positive and negative subjects followed by blood group A, B and AB. Majority (98.0%)o f the subjects were Rh(D) positive and only 2% were Rh negative. The predominant subgroup of ABO was A2 (14.1% ). The frequency of ABO blood groups in both Rh positive and negative subjects among the major Sudanese ethnic group was similar to that reported from neighbouring regions. (author)

    Recent epidemiological evidences revealed the higher prevalence of 'O' blood group in the residents of malaria-endemic areas. Also some data indicated preference of mosquitoes to 'O' group. The aim of this study was to determine ABO group ratio in the residents as well as ABO group preference of Anopheles in two malaria endemic areas in south of Iran. Agglutination method was used for ABO typing of residents. Field blood fed Anopheles specimens were tested against vertebrate DNA using mtDNA-cytB PCR-RFLP and then the human fed specimens were tested for ABO groups using multiplex allele-specific PCR. A total of 409 human blood samples were identified, of which 150(36.7%) were 'O' group followed by 113(27.6%), 109(26.7%), and 37(9.0%) of A, B, and AB groups respectively. Analyzing of 95 blood fed mosquitoes revealed that only four Anopheles stephensi had fed human blood with A(1), B(1), and AB(2) groups. Result of this study revealed high prevalence of O group in south of Iran. To our knowledge, it is the first ABO molecular typing of blood meal in mosquitoes; however, due to low number of human blood fed specimens, ABO host choice of the mosquitoes remains unknown. This study revealed that ABO blood preference of malaria vectors and other arthropod vectors deserves future research. Copyright © 2013 Elsevier Inc. All rights reserved.

    ABO and Rhesus blood systems are associated with type 2 Diabetes Mellitus (DM2). Gestational Diabetes (GDM) is a model to study DM. To study the association between GDM and ABO and Rhesus groups. A retrospective cohort study was performed in 1,078 women who gave birth to a singleton in Talca Regional Hospital, Chile, during 2008. We analyzed personal, obstetric, medical data and ABO and Rh blood groups. GDM was diagnosed in 6.6% of women. Age and body mass index were significantly associated with GDM. There were no differences in Rh blood groups (p = 0.604), while ABO groups were different between GDM and controls. B antigen was present in 3% of GDM women and in 10.8% of controls (p = 0.037), with an odds ratio of 0.25 after adjusting for other associated risk factors (p = 0.06). ABO group is suggested as a possible protector marker for GDM.

    The prevalence of ABO alleles is different in different populations, and many studies have shown a correlation between the occurrences of some diseases and different genotypes of ABO blood groups. The aim of this study was to determine whether there is a significant association between psychiatric syndromes and ABO blood groups. This case-control study involved 156 psychiatric patients and 303 healthy, unrelated, voluntary blood donors. Genomic DNA was isolated from blood on a QIAcube device using a QIAamp DNA Blood mini QIAcube kit. ABO genotyping on five basic ABO alleles was performed using allele-specific polymerase chain reaction analysis. Compared with healthy subjects, a significantly higher proportion of psychiatric patients had AB blood group (χ 2 =9.359, df=3, p=0.025) and, accordingly, a significantly higher incidence of A1B genotype (χ 2 =8.226, df=3, p=0.042). The odds ratio showed that psychiatric disorders occur almost three times more frequently in carriers of AB group compared to other blood groups. However, no statistically significant difference was found in the distribution of ABO blood groups among patients with different psychiatric diagnoses. Likewise, no correlations were found between ABO blood groups and other characteristics of the psychiatric patients (sex, psychiatric heredity, somatic comorbidity, suicidality). The results of this study support the hypothesis of an association between psychiatric disorders and ABO blood groups. The probability is that psychiatric disorders will occur almost three times more frequently in carriers of AB group compared to other ABO blood groups in the Croatian population.

    Despite being a recessive trait, the O blood group is the most frequent worldwide among the ABO blood types. Since running performance has been recognized as a major driver of evolutionary advantage in humans, we planned a study to investigate whether the ABO blood group may have an influence on endurance running performance in middle-aged recreational athletes. The study population consisted of 52 recreational, middle-aged, Caucasian athletes (mean age: 49±13 years, body mass index, 23.4±2.3 kg/m 2 ), regularly engaged in endurance activity. The athletes participated to a scientific event called "Run for Science" (R4S), entailing the completion of a 21.1 km (half-marathon) run under competing conditions. The ABO blood type status of the participants was provided by the local Service of Transfusion Medicine. In univariate analysis, running performance was significantly associated with age and weekly training, but not with body mass index. In multiple linear regression analysis, age and weekly training remained significantly associated with running performance. The ABO blood group status was also found to be independently associated with running time, with O blood type athletes performing better than those with non-O blood groups. Overall, age, weekly training and O blood group type explained 62.2% of the total variance of running performance (age, 41.6%; training regimen, 10.5%; ABO blood group, 10.1%). The results of our study show that recreational athletes with O blood group have better endurance performance compared to those with non-O blood group types. This finding may provide additional support to the putative evolutionary advantages of carrying the O blood group.

    ABO blood groups have been confirmed to be associated with cardiovascular diseases such as coronary artery disease. However, whether ABO blood group is correlated with coronary artery calcium (CAC) is still unknown. 301 patients with coronary artery calcium score (CACS) assessed by computed tomography were consecutively enrolled and divided into two groups: with calcium group (CACS>0, n=104) and without calcium group (CACS=0, n=197). Distribution of ABO blood groups was evaluated between the two groups. The percentage of A blood type was significantly higher (p=0.008) and O blood type was significantly lower (p=0.037) in the calcium group. Univariate regression analysis showed that age, total cholesterol, low density lipoprotein cholesterol, high-sensitivity C-reactive protein, A blood type were positively correlated with CAC, and O blood type was inversely associated with CAC. Multivariate regression analysis showed that A blood type was independently associated with CAC (odds ratio: 2.217, 95% confidence interval: 1.260-3.900, p=0.006) even after further adjustment for variables that were clearly different between the two groups. Our data has suggested for the first time that A blood type was an independent risk marker for CAC.

    The relationship between blood groups and some infections such as norovirus, cholera, and malaria has been reported. Despite the importance of brucellosis, there is a lack of data on the relationship between blood groups and brucellosis. Thus, in this study, we examined the relationship between blood groups and brucellosis. In this case-control study, the blood groups of 100 patients with brucellosis and 200 healthy individuals were studied. Exclusion criteria for the control group consisted of a positive Coombs Wright test or a history of brucellosis. The chi-square test was used to compare qualitative variables between the two groups. The variables that met inclusion criteria for the regression model were entered into the logistic regression model. A total of 43% patients were female and 57% male; 27% were urban and 73% rural. Regression analysis showed that the likelihood of brucellosis infection was 6.26 times more in people with blood group AB than in those with blood group O (Pblood group and brucellosis. People with blood group AB were susceptible to brucellosis, but no difference was observed for brucellosis infection in terms of blood Rh type.

    2008-12-01

    Full Text Available Abstract Background The high polymorphism rate in the human ABO blood group gene seems to be related to susceptibility to different pathogens. It has been estimated that all genetic variation underlying the human ABO alleles appeared along the human lineage, after the divergence from the chimpanzee lineage. A paleogenetic analysis of the ABO blood group gene in Neandertals allows us to directly test for the presence of the ABO alleles in these extinct humans. Results We have analysed two male Neandertals that were retrieved under controlled conditions at the El Sidron site in Asturias (Spain and that appeared to be almost free of modern human DNA contamination. We find a human specific diagnostic deletion for blood group O (O01 haplotype in both Neandertal individuals. Conclusion These results suggest that the genetic change responsible for the O blood group in humans predates the human and Neandertal divergence. A potential selective event associated with the emergence of the O allele may have therefore occurred after humans separated from their common ancestor with chimpanzees and before the human-Neandertal population divergence.

    The aim of this study was to determine the association of "ABO" and "Rhesus" blood groups with incidence of breast cancer. In this study, we identified 70 research documents from data based search engines including "PubMed", "ISI-Web of Knowledge", "Embase" and "Google Scholar". The research papers were selected by using the primary key-terms including "ABO blood type", "Rhesus" blood type and "breast cancer". The research documents in which "ABO" and "Rhesus" blood types and breast cancer was debated were included. After screening, we reviewed 32 papers and finally we selected 25 research papers which met the inclusion criteria and remaining documents were excluded. Blood group "A" has high incidence of breast cancer (45.88%), blood group "O" has (31.69%); "B" (16.16%) and blood group "AB" has (6.27%) incidence of breast cancer. Blood group "A" has highest and blood group "AB" has least association with breast cancer. Furthermore, "Rhesus +ve" blood group has high incidence of breast cancer (88.31%) and "Rhesus -ve" blood group has least association with breast cancer (11.68%). Blood group "A" and "Rhesus +ve" have high risk of breast cancer, while blood type "AB" and "Rhesus -ve" are at low peril of breast cancer. Physicians should carefully monitor the females with blood group "A" and "Rh +ve" as these females are more prone to develop breast cancer. To reduce breast cancer incidence and its burden, preventive and screening programs for breast cancer especially in young women are highly recommended.

    Indian population is characterized by the presence of various castes and tribal groups. Various genetic polymorphisms have been used to differentiate among these groups. Amongst these, the ABO blood group system has been extensively studied. There is no information on molecular genotyping of ABO blood groups from India. Therefore, the main objective of this study was to characterize the common A, B and O alleles by molecular analysis in some Indian population groups. One hundred samples from the mixed population from Mumbai, 101 samples from the Dhodia tribe and 100 samples from the Parsi community were included in this study. Initially, the samples were phenotyped by standard serologic techniques. PCR followed by single strand conformational polymorphsim (SSCP) was used for molecular ABO genotyping. Samples showing atypical SSCP patterns were further analysed by DNA sequencing to characterize rare alleles. Seven common ABO alleles with 19 different genotypes were found in the mixed population. The Dhodias showed 12 different ABO genotypes and the Parsis revealed 15 different ABO genotypes with six common ABO alleles identified in each of them. Two rare alleles were also identified. This study reports the distribution of molecular genotypes of ABO alleles among some population groups from India. Considering the extremely heterogeneous nature of the Indian population, in terms of various genotype markers like blood groups, red cell enzymes, etc., many more ABO alleles are likely to be encountered.

    The study was undertaken to correlate the blood groups and clinical presentations in malaria patients and to understand the differential host susceptibility in malaria. From October 2007 to September 2008, malaria positive patients' samples were evaluated in this study. Hemoglobin, total leukocyte count, and platelet count of each patient were done on an automated cell counter. After determining the blood groups, malarial species and the severity of clinical course were correlated. A total of 100 patients were included in the study, of which 63 cases were positive for Plasmodium falciparum and 37 cases were positive for P. vivax infection and 11 patients had mixed infection. The results of the blood groups showed 22 - 'A' group, 42 - 'B' group, 35 - 'O' group and 1 was 'AB' group. When the clinical courses between different groups were compared using the following parameters for severe infection--a parasitic load of >10/1000 RBCs, severe anemia with hemoglobin 101°F and other organ involvement, it was observed that 'O' group had an advantage over other the groups. The difference in rosetting ability between red blood cells of different 'ABO' blood groups with a diminished rosetting potential in blood group 'O' red blood cells was due to the differential host susceptibility. 'O' group had an advantage over the other three blood groups. Based on literature and the results of this study, the diminished rosetting potential in blood group 'O' red blood cells is suggested as the basis for the differential host susceptibility.

Aim: To explore the relationship between blood group typing, rotavirus gastroenteritis, and its severity in Egyptian children. Material and methods: A cross sectional case control study was conducted on 231 cases of acute gastroenteritis attending the outpatient clinic of Al-Zahraa University Hospital. Full history taking, clinical examination, and clinical data collection were done. Blood samples were collected for an ABO grouping. Stool samples were tested for viral gastroenteritis agents. Results : Rota positive cases of GE were significantly more prevalent among cases with blood group A (p < 0.05 and significantly less among cases with blood group B (p < 0.05. The rate of hospitalisation was highly significantly greater among cases with group A (p < 0.005, and significantly lower among cases with group AB and O (p < 0.05. As regards the degree of dehydration, moderate and severe cases were highly significant in groups A and O (p < 0.005. Rota-positive gastroenteritis showed significant positive correlations with indicators of severity such as hospitalisation, degree of dehydration, and duration of fever (p < 0.005. Conclusions : Blood group A is highly associated with paediatric rotavirus gastroenteritis. This could highlight an important risk factor, which could play a significant role for the pathogenesis of rotavirus gastroenteritis and severity as well. Furthermore, more intervention care could be needed for blood group A paediatric patients, if gastroenteritis especially rotavirus affect this group to avoid comorbidities.

    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 the relationship between ABO and Rhesus (D) blood groups and Behçet's disease in Turkish patients. Clinical data on gender, ABO, and Rhesus blood type of patients with BD were collected at the Kayseri Education and Research Hospital from 2005 to 2012. A total of 115 patients with BD were assessed for their association with ABO or Rhesus (D) blood groups and compared with the distribution of the blood groups of 25,701 healthy donors admitted to the Kayseri Education and Research Hospital Blood Center in 2010 and 2011. The distribution of ABO and Rhesus blood groups in patients with BD was similar to the healthy donors. No relationship was found between ABO or Rhesus blood groups and BD at our hospital. Further studies with a larger series and in different centers may be valuable for identifying the association between ABO or Rhesus (D) blood groups and BD.

    In B(A) phenotype, an autosomal dominant phenotype, there is a weak A expression on group B RBCs. We herein report a case of a probable B(A) phenotype in a first time 20-year old male donor. The cell and serum grouping were done using tube technique and also with blood grouping gel card (Diaclone, ABD cards for donors, BioRad, Switzerland). The antisera used were commercial monoclonal IgM type. To check for the weak subgroup of A, cold adsorption and heat elution was performed. The cell grouping was A weak B RhD positive while the serum grouping was B. There was no agglutination with O cells and the autologous control was also negative. It was a group II ABO discrepancy with or without group IV discrepancy. Results for both the eluate and last wash were negative. Hence, the possibility of weak subgroup of A was unlikely. Blood grouping gel card also showed a negative reaction in the anti-A column. One lot of anti-A was showing 'weak +' agglutination while the other lot was showing 'negative' reaction with the donor RBCs by tube technique. There was no agglutination observed with anti-A1 lectin. Our case highlights the serological characteristics of a B(A) phenotype. This case emphasizes the vital role of cell and serum grouping in detecting such discrepancies especially in donors which can lead to mislabeling of the blood unit and may be a potential risk for the transfusion recipient if not resolved appropriately.

    Numerous publications indicate that the prevalence of some infectious, neoplastic and immunological diseases are associated with ABO blood groups. The aim of this study was to verify whether ABO and Rh blood groups are associated with severe anaphylactic reactions after Hymenoptera stings. A study was undertaken of 71,441 Caucasian subjects living in the same geographic area. The study group included 353 patients with diagnosed systemic anaphylaxis to Hymenoptera venom. Control group included 71,088 healthy blood donors. Frequencies of ABO and Rhesus groups in the study and control groups were compared using univariate and multivariate analyses. No statistically significant interactions were observed between the ABO blood group and anaphylactic reactions to Hymenoptera.

    The phenotypic "ABO" blood groups are inherited antigenic substances which are found on the surface of red blood cells in addition to other tissues. Certain hypothesis advocates that genetic predisposition like "ABO" blood group would be associated with occurrence of diseases including type 2 diabetes. This study aimed to investigate the potential association between "ABO" and "Rhesus" blood groups with type 2 diabetes. We identified 47 research documents in a data based search including ISI-Web of Science, EMBASE and PubMed. Literature was explored using the key terms including "ABO blood groups" "type 2 diabetes". Studies in which "ABO" blood types and diabetes mellitus were discussed included without restrictions of research documents, types, status and language of the publications. Finally, 15 publications which matched our criteria were included, and remaining studies were excluded. Blood group "B" was associated with high incidence of type 2 diabetes and blood group "O" has a minimum association with type 2 diabetes. Blood group "A" and "AB" were almost equally distributed in both diabetic and non-diabetic population. However, we were unable to find an association between "Rh+ve" and "Rh-ve" blood groups with type 2 diabetes. Subjects with blood group "B" are at high risk while individuals with blood group "O" are at low peril of evolving type 2 diabetes. It is suggested that subjects with blood group "B" should be closely monitored by physicians as these subjects have an increased risk of type 2 diabetes.

    The ABO blood group system is composed of complex carbohydrate molecules (i.e., the A, B, and H determinants) that are widely expressed on the surface of red blood cells and in a variety of other cell and tissues. Along with their pivotal role in transfusion and transplantation medicine, the ABO antigens participate in many other physiological processes and, in particular, are important determinants of von Willebrand factor and factor VIII circulating plasma levels. The precise influence of the ABO system on hemostasis has led the way to the investigation of a putative implication in the risk of developing cardiovascular disorders. Along with the underlying molecular mechanisms, the current knowledge on the role of ABO blood group antigens in both the thrombotic and hemorrhagic risk will be summarized in this narrative review.

    Association of keratoconus (KC) with genetic predisposition and environmental factors has been well documented. However, no single study has investigated the possible relationship between ABO and Rh blood groups and KC. A case-control study was designed in a university hospital enrolling 214 patients with KC in the case group and equal number of age- and sex-matched healthy subjects in the control group. Primary characteristics, ABO blood group, and Rh factors were compared between the two groups. Topographic findings of KC eyes and the severity of the diseases were investigated according to the distribution of the blood groups. Blood group O and Rh(+) phenotype were most frequent in both groups. There was no significant difference between the two groups in terms of ABO blood groups or Rh factors. Mean keratometery (K), central corneal thickness, thinnest corneal thickness, flat K, steep K, sphere and cylinder, spherical equivalent, and uncorrected visual acuity were all similar between ABO blood groups and Rh(+) and Rh(-) groups. However, the best spectacle-corrected visual acuity (BCVA) had the highest value in AB blood group (0.35 ± 0.22 logMAR, P=0.005). Moreover, the blood group AB revealed the highest frequency for grade 3 KC, followed by grades 1, 2, and 4 (P=0.003). We observed no significant excess of any particular blood group among KC cases compared with healthy subjects. Except BCVA, none of the keratometric or topographic findings was significantly different between blood groups.

    Investigation into predictors for treatment outcome is essential to improve the clinical efficacy of therapeutic multipotent mesenchymal stromal cells (MSCs). We therefore studied the possible harmful impact of immunogenic ABO blood groups antigens - genetically governed antigenic determinants - at all given steps of MSC-therapy, from cell isolation and preparation for clinical use, to final recipient outcome. We found that clinical MSCs do not inherently express or upregulate ABO blood group antigens after inflammatory challenge or in vitro differentiation. Although antigen adsorption from standard culture supplements was minimal, MSCs adsorbed small quantities of ABO antigen from fresh human AB plasma (ABP), dependent on antigen concentration and adsorption time. Compared to cells washed in non-immunogenic human serum albumin (HSA), MSCs washed with ABP elicited stronger blood responses after exposure to blood from healthy O donors in vitro, containing high titers of ABO antibodies. Clinical evaluation of hematopoietic stem cell transplant (HSCT) recipients found only very low titers of anti-A/B agglutination in these strongly immunocompromised patients at the time of MSC treatment. Patient analysis revealed a trend for lower clinical response in blood group O recipients treated with ABP-exposed MSC products, but not with HSA-exposed products. We conclude, that clinical grade MSCs are ABO-neutral, but the ABP used for washing and infusion of MSCs can contaminate the cells with immunogenic ABO substance and should therefore be substituted by non-immunogenic HSA, particularly when cells are given to immunocompentent individuals.

    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. 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 age was 52 ± 11 years. The frequency of ABO-Rh blood groups was compared to the frequency of these blood groups in the West-Azerbaijan province, Iran; general population. Blood groups distribution among CSX patients showed phenotypes A, B, AB, O and Rh negative as 33.1%, 21.9%, 9.3%, 35.8%, and 7.9%, respectively. According to our results, there were no differences in ABO-Rh blood groups distribution between CSX patients and normal population. These data suggest that ABO-Rh blood groups might be unassociated with CSX.

    Inherited ABO blood groups have been shown to play possible contributions in the pathogenesis of various gynecologic and non-gynecologic carcinomas. With regard to gynecologic carcinomas, there is a confined number of studies that explored the relationship between ABO blood group and endometrial carcinoma (EC) in the PubMed-indexed literature. To the best of our knowledge, no such study has ever been conducted in Saudi Arabia. Our study has two objectives: (I) to determine the prevalence of ABO blood groups among Saudi patients with EC, and (II) to explore the relationship between ABO blood group and several clinico-pathological prognostic parameters (namely: menopausal status [age], body mass index [BMI], tumor grade, FIGO [Fédération Internationale de Gynécologie et d'Obstétrique] stage and recurrence) in Saudi patients with EC. A retrospective cross-sectional study from 01-January-2010 to 31-July-2014 was conducted at King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia - a referral tertiary healthcare institute. One-hundred and fourteen patients (n=114) were included in the study. Clinico-pathological data were extrapolated from medical records, and their association with ABO blood groups were evaluated. Categorical data were presented as number of cases (n) and percentages (%). Two-tailed Chi-square test was used for univariate analysis. For all purposes, p values 28 kg/m 2 (84.2%), diagnosed with early FIGO stage I-II (76.3%) and developed no recurrence (86.8%). The frequencies of ABO blood group types A, B, AB, and O were 28.1%, 12.3%, 3.5% and 56.1%, respectively. When ABO blood groups were analyzed as four different types (A, B, AB and O), O-type was the most common ABO blood group in pre- and post-menopausal EC patients (43.8% and 58.2%, respectively; p=0.14). There were no statistically significant correlations between ABO blood groups and all the examined clinico-pathological factors. Moreover, when ABO blood groups were

    To study the association of ABO blood groups with major ischaemic heart disease risk factors. Setting: Department of Cardiology, Mayo hospital, Lahore over a period of two years from January 2008 to December 2009. Study Design: Analytic comparative study. Subjects and Methods: The study group included 907 patients of ischaemic heart disease (IHD). The distribution of ABO blood groups in IHD patients was compared for presence or absence of major IHD risk factors. Data was analyzed using SPSS 16. ANOVA and Chi-square tests for significance were used. P-value less than 0.05 was taken as significant. Results: In this study, the following pattern of ABO blood groups was observed in IHD patients : blood group A 251 (27.67%); blood group B 329 (36.27%); blood group O 235 (25.91%); blood group AB 92 (10.14%). We found no relation-ship of ABO blood groups with age (p-value = 0.234), gender (p-value = 0.093), hypertension (p-value = 0.230), diabetes mellitus (p-value = 0.801), family history of IHD (p-value = 0.277), transverse ear lobe crease (p-value = 0.231), total cholesterol (p-value = 0.797), triglycerides (p-value = 0.351), low density lipoprotein (p-value = 0.078), high density lipoprotein (p-value = 0.114). Similarly no relationship was found of smoking, weight, height and body mass index with ABO blood groups, p-values 0.428, 0.528, 0.908 and 0.455 respectively. Conclusion: There is no association of ABO blood groups and major ischaemic heart disease risk factors. (author)

    Background Placental Protein 13 (PP13), an early biomarker of preeclampsia, is a placenta-specific galectin that binds beta-galactosides, building-blocks of ABO blood-group antigens, possibly affecting its bioavailability in blood. Methods and Findings We studied PP13-binding to erythrocytes, maternal blood-group effect on serum PP13 and its performance as a predictor of preeclampsia and intrauterine growth restriction (IUGR). Datasets of maternal serum PP13 in Caucasian (n = 1078) and Hispanic (n = 242) women were analyzed according to blood groups. In vivo, in vitro and in silico PP13-binding to ABO blood-group antigens and erythrocytes were studied by PP13-immunostainings of placental tissue-microarrays, flow-cytometry of erythrocyte-bound PP13, and model-building of PP13 - blood-group H antigen complex, respectively. Women with blood group AB had the lowest serum PP13 in the first trimester, while those with blood group B had the highest PP13 throughout pregnancy. In accordance, PP13-binding was the strongest to blood-group AB erythrocytes and weakest to blood-group B erythrocytes. PP13-staining of maternal and fetal erythrocytes was revealed, and a plausible molecular model of PP13 complexed with blood-group H antigen was built. Adjustment of PP13 MoMs to maternal ABO blood group improved the prediction accuracy of first trimester maternal serum PP13 MoMs for preeclampsia and IUGR. Conclusions ABO blood group can alter PP13-bioavailability in blood, and it may also be a key determinant for other lectins' bioavailability in the circulation. The adjustment of PP13 MoMs to ABO blood group improves the predictive accuracy of this test. PMID:21799738

    ABO blood groups are associated with some important chronic diseases. Previous studies have observed an association between ABO blood group and risk for obesity. This study aimed to determine whether there is an association between ABO blood groups and obesity in apparently healthy attendees of primary healthcare (PHC) centers in Arar city, Northern Saudi Arabia. This cross-sectional study included 401 participants aged 15 years and older attending three randomly selected PHC centers in Arar city. Data were collected by means of personal interview using a predesigned questionnaire. Anthropometric examination included height and weight measurements with calculation of BMI. ABO and Rh blood groups were determined. The majority of the participants were female (70.8%). The mean±SD age was 28.6±9.1 years. Only 5.7% were underweight. Both normal and overweight participants were equal in number and constituted 28.4%, whereas obese individuals constituted 37.4% with a mean BMI of 28.56±8.0. Blood group O was the most common (44.1%), followed by A (30.9%), B (18.7%), and AB (6.2%). Rh-positive cases constituted 87.0%. Blood group O was the most common type among the obese individuals (44.7%), followed by A, B, and AB groups (30, 20, and 5.3%, respectively). BMI was highest (28.8±9.2) in blood group O. There were no statistically significant differences between different ABO blood groups as regards BMI, Rh, and sex. Moreover, there was no statistically significant difference between Rh type and BMI. The prevalence of obesity and overweight is high in the population attending PHC centers of Arar city, Northern Saudi Arabia. There is no association between overweight, obesity, and ABO blood groups or Rh.

  16. Is there an association of ABO blood groups and Rhesus factor with alopecia areata?

    Alopecia areata (AA) is an autoimmune disease characterized by noncicatricial hair loss localized on hair, beard, mustache, eyebrow, eyelash, and sometimes on the body. Although etiopathogenesis is not fully understood, many studies show remarkable associations between various diseases and ABO blood groups. However, there is no study with AA and blood groups. Healthy people and patients with AA were included in this study. A total of 155 patients with AA and 299 healthy controls were included in the study. ABO blood group distribution in patients with AA and distribution of healthy donors were similar. However, Rhesus factor positivity in the AA group was significantly higher than in healthy donors. The relationship between stress and AA was high as known. But, ABO blood group and Rhesus factor were not in a significant connection with stress. We conclude that there was no association between ABO blood group and AA, but the observed distribution of Rhesus blood group differed slightly but significantly from that of the healthy population. The result of the study shows a small but statistically significant difference in the Rh blood group between patients with AA and the healthy population blood groups. This result is important because it suggests that genetic factors may influence the development of AA. The role of blood groups in the development of AA remains to be determined. We believe that the studies which will be carried out in other centers with wider series will be more valuable to support this hypothesis. © 2018 Wiley Periodicals, Inc.

    Although the study on the relationship between ABO blood groups and coronary atherosclerosis has a long history, few data is available regarding ABO to severity of coronary atherosclerosis in a large cohort study. Therefore, the present study aimed to investigate the relation of the ABO blood groups to the severity of coronary atherosclerosis assessed by Gensini score (GS) in a large Chinese cohort undergoing coronary angiography. A total of 2919 consecutive patients undergoing coronary angiography were enrolled, and their baseline characteristics and ABO blood groups were collected. The GS was calculated as 1st tertile (0-10), 2nd tertile (11-36), 3rd tertile (>36) according to angiographic results. The relation of the ABO blood groups to GS was investigated. The frequency of blood group A was significantly higher in the upper GS tertiles (24.4% vs. 28.2% vs. 29.5%, p = 0.032). Multivariable linear regression analysis revealed that blood group A was independently associated with GS (β = 0.043, p = 0.017). Likewise, multivariable logistic regression analysis showed that group A remained significantly associated with mid-high GS (OR = 1.44, 95% CI 1.16-1.80, p = 0.001), and the group O was showed as a protective factor (OR = 0.77, 95% CI = 0.65-0.92, p = 0.004). In this large Chinese cohort study, the data indicated that there was an association between ABO blood groups and the severity of coronary atherosclerosis. Moreover, the blood group A was an independent risk factor for serious coronary atherosclerosis. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Toxoplasma gondii infects humans through the gastrointestinal tract (GIT, which elicits humoral immune response with specific antibodies. The expression of the ABO blood group glycoconjugates also occurs in this same system and may influence the human susceptibility of infection by T. gondii. The aim of the present study was to investigate the association between ABO blood group phenotypes and the presence of anti-T. gondii antibodies. Data - including age, results of serology tests for T. gondii infection and ABO blood group phenotypes - were assembled from the medical records of 1,006 pregnant women attended in the Base Hospital of the Medical School of São José do Rio Preto, Brazil, between 2001 and 2004. The chi-square test was used to compare the results with the level of significance set at 5%. Of the studied cases, 64.1% (645/1006 and 35.9% (391/1006 presented respectively positive and negative serology tests for anti-T. gondii antibodies. The mean age of those who tested positive was higher than those with negative serology tests (p = 0.0004. The frequencies of ABO blood group phenotypes were similar in those with and without anti-T. gondii antibodies (p = 0.35. In conclusion, the ABO blood group system is not associated with the presence or absence of anti-T. gondii antibodies.

    The role of genetic factors in the development of cancer is widely accepted. Data on the role of ABO blood group and Rh factor in breast cancer is inconclusive. The aim of this study was to investigate the presence of a possible association between HER2 (+) breast cancer in Turkish women and ABO blood groups and Rh factor. In 294 female patients with HER2 (+) breast cancer, ABO blood groups and Rh factor were examined. The relationship of blood groups with age, menopausal status, and family history of cancer, estrogen receptor (ER), progesterone receptor (PR) and HER2 status of these patients was evaluated. Blood groups distribution of 22,821 healthy blood donors was also assessed and compared with the patients' blood groups distribution. The median patient age was 47 years (range 20-80) and 56% of the patients were premenopausal. ER and PR were positive in 50 and 60% of the patients, respectively. Overall, the ABO blood group distribution of the 294 HER2 (+) breast cancer patients was similar to that of the healthy blood donors (p=0.36). Likewise there was no correlation between blood type and ER, PR and menopausal status. Rh (-) patients had more frequent family cancer history and this difference was significant for patients with blood group B Rh (-) and O Rh (-) (p = 0.04). In the present study we didn't find any relationship between HER2 status and ABO blood group and Rh factor. However, further studies with larger number of patients are needed to establish the role (if any) of blood groups in patients with breast cancer.

    The ABO blood types related to morphological characteristics of atherosclerosis plaque are not clear. We aimed to evaluate the relationship between ABO blood groups and the coronary plaque characteristic. We retrospectively identified the target lesions in 392 acute coronary syndrome patients who underwent optical coherence tomography examination before stenting. Subjects were divided into different groups according to different blood types. The fibrous cap thickness was significantly thicker in O type compared with non-O type (0.075 ± 0.033 mm versus 0.061 ± 0.024, p blood type groups even between O type and non-O type group ( p > 0.05). The plaques of O type blood group were exhibited more stably compared with non-O type blood group. Moreover, the non-O type blood group have more serious coronary artery stenosis than O type blood group.

    Although previous studies have demonstrated the relationship between ABO blood groups and cardiovascular disease, the association of ABO blood type with spontaneous recanalization (SR) in patients with acute myocardial infarction (AMI) has not been previously investigated. We performed an initial exploratory study on the association of ABO blood groups with the presence of SR in 1209 patients with AMI. They were divided into two groups according to the thrombolysis in myocardial infarction (TIMI) grades: no-SR group (TIMI 0-1, n = 442) and SR group (TIMI 2-3, n = 767). To confirm our primary findings, data from a second AMI population (n = 200) was analyzed. In the initial data, SR group had a significantly higher percentage of blood type O and a lower percentage of blood type A compared to the no-SR group. Multivariate logistic regression analysis showed that blood type O was positively associated with SR (odds ratio: 1.40, 95% confidence interval: 1.05-1.87, p = .02), and this finding was confirmed in our second population. The present study demonstrates that blood type O was independently and positively associated with an open culprit artery in patients with AMI, suggesting that the ABO blood type is not only associated with the susceptibility to coronary artery disease but also to spontaneous reperfusion in AMI patients.

    To investigate this association between ABO blood groups and coronary heart disease (CHD) in the Chinese Guangxi Zhuang population. From August 2010 to April 2013, we performed a case-control study in a Chinese Zhuang population, which included 1 024 CHD cases and 1 024 age and gender-matched non-CHD controls. The ABO blood groups and biological variables were measured by standard laboratory procedures. The Gensini score was used to evaluate the severity of coronary artery stenosis. Compared to non-CHD control group, CHD group had higher levels of fasting blood glucose ((6.71 ± 6.72) mmol/L vs. (4.98 ± 1.55) mmol/L, P blood groups were associated with CHD risk in the Chinese Zhuang population. Compared with group O, the group B individuals had a higher risk of CHD (OR = 2.33, 95% CI 1.88-2.90, P group O subjects in the CHD group, and MACE at 1-year follow-up was similar between ABO blood groups of CHD individuals. ABO blood groups are associated with CHD risk in the Chinese Zhuang population.

    We examined the association of ABO blood groups with the different types of head and neck cancers. 195 diagnosed cases and 801 controls were selected from a Greek tertiary cancer center. Information regarding type of head and neck cancer and ABO blood group was collected and registered. The O blood group was found to be most prevalent followed by A, B and AB among the controls, whereas blood group A followed by O, B and AB was most prevalent among cancer patients. The difference among the distribution between the cases and controls was statistically significant in blood group A (pblood group A had 1.52-fold higher risk of developing head and neck cancer compared to people of other blood groups. Blood group A was found to be a potential risk factor for the development of head and neck cancers.

    Endometriosis is a common gynaecological disease that affects quality of life for women. Several studies have revealed that both environmental and genetic factors contribute to the development of endometriosis. The aim of this study was to investigate the distribution of ABO and Rh blood groups in Iranian women with endometriosis who presented to two referral infertility centers in Tehran, Iran. In this case-control study, women who referred to Royan Institute and Arash Women's Hospital for diagnostic laparoscopy between 2013 and 2014 were assessed. Based on the laparoscopy findings, we categorized the women into two groups: endometriosis and control (women without endometriosis and normal pelvis). Chi-square and logistic regression tests were used for data analysis. In this study, we assessed 433 women, of which 213 patients were assigned to the endometriosis group while the remaining 220 subjects comprised the control group. The most frequent ABO blood group was O (40.6%). The least frequent blood group was AB (4.8%). In terms of Rh blood group, Rh+ (90.1%) was more frequent than Rh- (9.9%). There was no significant correlation between ABO (P=0.091) and Rh (P=0.55) blood groups and risk of endometriosis. Also, there was no significant difference between the two groups with regards to the stage of endometriosis and distribution of ABO and Rh blood groups (P>0.05). Although the O blood group was less dominant in Iranian women with endometriosis, we observed no significant correlation between the risk of endometriosis and the ABO and Rh blood groups. Endometriosis severity was not correlated to any of these blood groups. Copyright© by Royan Institute. All rights reserved.

    The variation in ABO blood groups is reported to be associated with multiple diseases. Infliximab (IFX) has been widely used in the treatment of Crohn's disease (CD). We aim to investigate the distribution of ABO blood groups in Chinese patients with CD and to explore its impact on response to IFX. Patients with CD were consecutively recruited to the study between 2007 and 2014. CD patients receiving IFX therapy were followed for at least two years. In 293 patients with CD, most patients (40.6%) had blood type O (119/293). The odds ratio (OR) of CD in blood type O patients was 1.06 (95%CI: 0.6-1.86; p=0.84) compared to all other blood types. Among those CD patients, 107 patients received IFX treatment. One year after the first course of IFX, a significant association was found between the overall ABO system and outcomes of IFX treatment (pblood type AB (OR=4.42, 95% CI: 1.04-18.76; p=0.044) were more likely to achieve mucosal healing, while CD patients with blood type A had a high risk of losing response (OR=0.38, 95% CI: 0.15-0.96; p=0.040). ABO blood groups are not associated with prevalence of CD. Patients with blood type AB had a better response to IFX while those with blood type A appeared to have a risk of losing response to IFX.

    Full Text Available Introduction. ABO blood group genotyping is a new technology in hematology that helps prevent adverse transfusion reactions in patients. Identification of antigens on the surface of red blood cells is based on serology; however, genotyping employs a different strategy and is aimed directly at genes that determine the surface proteins. ABO blood group genotyping by real-time PCR has several crucial advantages over other PCR-based techniques, such as high rapidity and reliability of analysis. The purpose of this study was to examine nucleotide substitutions differences by blood types using a PCR-based method on Kazakh blood donors.Methods. The study was approved by the Ethics Committee of the National Center for Biotechnology. Venous blood samples from 369 healthy Kazakh blood donors, whose blood types had been determined by serological methods, were collected after obtaining informed consent. The phenotypes of the samples included blood group A (n = 99, B (n = 93, O (n = 132, and AB (n = 45. Genomic DNA was extracted using a salting-out method. PCR products of ABO gene were sequenced on an ABI 3730xl DNA analyzer (Applied Biosystems. The resulting nucleotide sequences were compared and aligned against reference sequence NM_020469.2. Real-time PCR analysis was performed on CFX96 Touch™ Real-Time PCR Detection System (BioRad.Results. Direct sequencing of ABO gene in 369 samples revealed that the vast majority of nucleotide substitutions that change the ABO phenotype were limited to exons 6 and 7 of the ABO gene at positions 261, 467, 657, 796, 803, 930 and 1,060. However, genotyping of only three of them (261, 796 and 803 resulted in identification of major ABO genotypes in the Kazakh population. As a result, TaqMan probe based real-time PCR assay for the specific detection of genotypes 261, 796 and 803 was developed. The assay did not take into account several other mutations that may affect the determination of blood group, because they have a

    Portable, on-site blood typing methods will help provide life-saving blood transfusions to patients during an emergency or natural calamity, such as significant earthquakes. We have previously developed waveguide-mode (WM) sensors for forward ABO and Rh(D) blood typing and detection of antibodies against hepatitis B virus and hepatitis C virus. In this study, we evaluated a WM-sensor for reverse ABO blood typing. Since reverse ABO blood typing is a method for detection of antibodies against type A and type B oligosaccharide antigens on the surface of red blood cells (RBCs), we fixed a synthetic type A or type B trisaccharide antigen on the sensor chip of the WM sensor. We obtained significant changes in the reflectance spectra from a WM sensor on type A antigen with type B plasma and type O plasma and on type B antigen with type A plasma and type O plasma, and no spectrum changes on type A antigen or type B antigen with type AB plasma. Signal enhancement with the addition of a peroxidase reaction failed to increase the sensitivity for detection on oligosaccharide chips. By utilizing hemagglutination detection using regent type A and type B RBCs, we successfully determined reverse ABO blood groups with higher sensitivity compared to a method using oligosaccharide antigens. Thus, functionality of a portable device utilizing a WM sensor can be expanded to include reverse ABO blood typing and, in combination with forward ABO typing and antivirus antibody detection, may be useful for on-site blood testing in emergency settings.

    The aim of study was to: 1) examine the relationship between ABO blood groups and extent of coronary atherosclerosis in patients with chronic coronary artery disease (CAD), 2) compare ABO blood groups distribution in CAD patients and general population, 3) examine possible differences in traditional risk factors frequency in CAD patients with different ABO blood groups. In the 646 chronic CAD patients (72.4% males) coronary angiograms were scored by quantitative assessment using multiple angiographic scoring system, Traditional risk factors were self reported or measured by standard methods. ABO blood distribution of patients was compared with group of 651 healthy blood donors (74.6% males). Among all ABO blood group patients there was no significant difference between the extent of coronary atherosclerosis with regard to all the three scoring systems: number of affected coronary arteries (P = 0.857), Gensini score (P = 0.818), and number of segments narrowed > 50% (P = 0.781). There was no significant difference in ABO blood group distribution between CAD patients and healthy blood donors. Among CAD patients, men with blood group AB were significantly younger than their pairs with non-AB blood groups (P = 0.008). Among CAD patients with AB blood group, males groups (P = 0.003). No association between ABO blood groups and the extent of coronary atherosclerosis in Croatian CAD patients is observed. Observation that AB blood group might possibly identify Croatian males at risk to develop the premature CAD has to be tested in larger cohort of patients.

    Background: The ABO blood group antigens are present on the surface of red blood cells and various epithelial cells. As the majority of human cancers are derived from epithelial cells, changes in blood group antigens constitute an important aspect of human cancers. The aim of the study was to establish clinical usefulness of ABO blood group as a predisposing factor in early diagnosis and management of patients with oral precancerous lesions/conditions. Materials and Methods: The study sample consisted of 50 control and 50 oral precancer (25 leukoplakia and 25 Oral Submucous Fibrosis) confirmed by histopathologic examination. All samples were subjected to blood group testing and their prevalence was compared by Z-test using STATA version 8. Results: The "A" blood group was prevalent among the precancerous group. Significant differences on prevalences of blood groups were found (P blood group. Conclusion: Blood group type should be considered along with other risk factors to understand the individual patient's risk and further studies in larger samples with inclusion of Rh factor is needed to elucidate the relationship with ABO blood group types.

    The study of lip-print pattern (cheiloscopy) is a scientific method for personal identification and plays a major role in forensic and criminal investigations. To compare the lip print patterns in Kerala and Maharashtra population and correlate between ABO blood groups. Two hundred subjects, 100 from Maharashtra and 100 from Kerala were considered for the study. Lip prints were recorded, analyzed according to Tsuchihashi classification. The lip print patterns were compared in the two populations, correlated in ABO blood groups. The data obtained was statistically analyzed with SPSS software using chi-square test. In our study, predominant lip print pattern observed in Kerala population was type IV (53%) and Maharashtra population was type II (42%). The difference between the two population was statistically significant (pblood groups had type II lip print predominance. Subjects with B+, AB+ and O+ blood groups had type IV predominance. The lip print patterns do not show any correlation in ABO blood groups. Lip prints are unique to each individual and are different even in two persons. Lip print patterns were different in the two sub populations studied, and they showed no correlation in ABO blood groups.

    The Central Nervous System (CNS) lesions show considerable geographic and racial variations with respect to the incidence and the pattern of distribution of lesions. The ABO blood status is a readily accessible factor in genetic constitution of the patients. It has been shown to be associated with many diseases. But the influence of blood group status on the pathogenesis of brain tumours is still unclear. To study various histopathological patterns of CNS lesions and to evaluate the association of CNS tumours with the distribution of ABO blood groups in documented cases. In the present study, 147 cases were analyzed. It was an analytical type of study, done at JSS Medical College, Mysore, over a period of 2 years and 8 months from January 2009 to August 2011. Histopathology slides were routinely stained by Haematoxylin and Eosin (H&E) stain. Special stains were performed in selected cases. Blood group of the patients and the control group were documented. Blood group distribution pattern was assessed in relation to histopathological diagnosis of various CNS tumours. Histopathological diagnosis of 147 cases included neoplastic lesions (84.35%) and non-neoplastic lesions (15.64%). Neoplastic lesions (84.35%) constituted the majority, which included neuroepithelial tumours (29.25%) as predominant pattern. Non-neoplastic lesions constituted only 15.64%, which included inflammatory lesion (8.16%) as the predominant pattern. ABO blood group data was available in 92 cases (84.4%) of neoplastic lesions, which included 71 cases (48.29%) of primary CNS neoplasms categorized according to WHO grades. The control group constituted 21,067 healthy voluntary donors. Blood group O was the most frequent blood group in neoplastic lesions (40.21%) and primary CNS neoplasms categorized according to WHO grades (45.07%). The association between the CNS neoplasms and ABO blood groups was not statistically significant (p = 0.055). But a definite change in the pattern of distribution of ABO

    Recent studies have demonstrated associations between ABO blood groups and prognosis in various types of cancers. The aim of this study was to investigate the association between ABO blood groups and biochemical recurrence (BCR) after radical prostatectomy (RP). A total of 555 patients with prostate cancer who underwent RP were included in the study. No patients received neoadjuvant and/or adjuvant therapy. The effect of ABO blood groups on BCR was examined using univariate and multivariate analyses. During the follow-up period (mean, 52.0 months), 166 patients (29.9%) experienced BCR, with a 5-year BCR-free rate of 67.3%. Although the ABO blood group was not a significantly associated with BCR in the univariate analysis, it was an independent predictor of BCR in the multivariate analysis: blood type O patients had a significantly lower risk of BCR compared to type A patients (Hazard ratio, 0.608; 95% confidence interval, 0.410-0.902; P = 0.014). Further analyses revealed that surgical margin status confounded the assessment of the association between the ABO blood group and BCR. In the analyses of patients with a negative surgical margin, the 5-year BCR-free rate in blood type O patients was a significantly higher than that in type A patients (91.2% vs. 71.0%; P = 0.026). Blood type O is significantly associated with a decreased risk of biochemical recurrence after radical prostatectomy. Further studies are needed to clarify the nature of this association.

    Glioblastoma is a highly malignant brain tumour that usually leads to death. Several studies have reported a link between the distribution of ABO blood group antigens and a risk of developing specific types of cancer, although no consensus has been reached. This study aims to investigate the relationship between the distribution of ABO blood group antigens and the incidence of glioblastoma. The study cohort consisted of 115 glioblastoma patients who were diagnosed at King Abdullah University Hospital, Jordan, between 2004 and 2015. Three different patient populations made up three control groups and these were selected from among patients at the same institution between 2014 and 2015 as follows: 3,847 healthy blood donors, 654 accidental trauma patients admitted to the Departments of Neurosurgery and Orthopaedics, and 230 age- and sex-matched control subjects recruited blindly from the Departments of Paediatrics and Internal Medicine. There was a significant association between the distribution of ABO blood group antigens and the incidence of glioblastoma. Post hoc residual analysis revealed that individuals with group A had a higher than expected chance of developing glioblastoma, while individuals with group O had a lower than expected chance. Furthermore, individuals with group A were found to be at a 1.62- to 2.28-fold increased risk of developing glioblastoma compared to individuals with group O. In the present study, we demonstrate that, in Jordan, individuals with group A have an increased risk of developing glioblastoma, while individuals with group O have a reduced risk. These findings suggest that the distribution of ABO blood group antigens is associated with a risk of brain tumours and may play an important role in their development. However, further clinical and experimental investigations are required to confirm this association.

    Blood grouping is conventionally done with invasive method by taking blood samples. The objective of this study is to determine blood group with uninvasive procedure by taking fingerprints of the participants and know the associations between their fingerprints and blood groups. Seven hundred participants of both genders with no any age limitation from Manipal Teaching Hospital and Manipal College of Medical Sciences were randomly selected. The blood grouping was done by cross reacting blood sample with the antibodies. The fingerprints were taken with the help of stamp pad imprinting the finger ridges over A4 size white papers. The loop, whorl and arch patterns were studied. O+ve blood group 224 (32%) was most prevalent among 700 participants. The loop pattern was highly distributed 3708 (53%) in all blood groups except in A-ve blood group with highest distribution of whorl 20 (40%). The mean comparisons of specific fingerprint in total and also in individual fingers with different ABO and ABO-Rh blood groups showed no any statistical association with P>0.05. However, the loop distribution in individual finger was highest in right middle finger (M) of B-ve blood group 5 (10%). The whorl distribution in individual finger was highest in right index (I), left thumb (T) and left ring (R) fingers of AB+ve blood group 20 (5.5% each). Similarly, the arch distribution was highest in right index fingers of A-ve blood group 3 (6%). The mean comparison of different fingerprints with ABO and Rh blood groups showed no significant statistical association concluding fingerprints cannot be used for blood grouping.

    Full Text Available 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 questionnaire was used to collect data. Blood grouping was done using monoclonal antibodies. Thin and thick blood films were examined for Plasmodium parasites. Data were analyzed using SPSS version 20.0. Results. A total of 416 blood donors participated with median age of 22±0.29 (median ± standard error of the mean. Distribution of ABO phenotypes, in decreasing order, was O (175, 42.1%, A (136, 32.7%, B (87, 20.9%, and AB (18, 4.3%. Most of them were Rh+ (386, 92.8%. The overall malaria prevalence was 4.1% (17/416. ABO blood group is significantly associated with malaria infection (P=0.022. High rate of parasitemia was seen in blood group O donors (6.899, P=0.003 compared to those with other ABO blood groups. Conclusion. Blood groups O and AB phenotypes are the most and the least ABO blood groups, respectively. There is significant association between ABO blood group and asymptomatic malaria parasitemia.

    Human beings have few characteristics that are unique from others. Lip prints are one of such feature. They are not changed throughout the life and are not influenced by injuries, diseases, or environmental changes. According to the various antigen-antibody reactions in the bloodstream, different individuals have specific blood groups. To study the distribution of lip print patterns among individuals with different ABO and Rh blood groups and also to know the relation between their characters and blood groups. In the present study, lip prints were collected randomly from 85 individuals, and their blood group matching was performed. This is to identify the most common lip print type and to know any association between lip print types and blood groups. Tsuchihashi's classification of lip prints was used to compare with the ABO and Rh blood grouping systems. It was observed that in individuals with B+, A+, and O- blood groups, predominant pattern was Type IV and individuals having blood group O+ and AB+ common lip print pattern was Type II. This study showed strong association between lip print patterns and ABO blood groups as some blood groups were not included in statistical analysis; further studies including larger sample are essential to substantiate the results. Correlating lip print with blood group helps in identification of the suspects. Along with lip prints, another biological record that remains unchanged throughout the lifetime of a person is the blood group. Determining the blood group of a person from the samples obtained at the site of crime and also recovering lip prints from site can help identify a person.

    Phenotype studies of ABO blood groups in most Amerindian populations revealed the exclusive presence of group O. Since group O is the result of the absence of glycosyltransferase activity, its molecular bases may be heterogeneous. We carried out ABO blood group genotyping by analysis of DNA of 30 Indians from 2 Amazonian tribes (Yanomami and Arara), and compared the findings with other populations (Caucasians and Blacks). Two segments of the glycosyltransferase gene were amplified by PCR and digested with KpnI or AluI to detect deletion or base change at positions 258 and 700, respectively. For all subjects, the gene basis of blood group O is the deletion of a single nucleotide at position 258 of the glycosyltransferase A gene, similar to that observed in Caucasoids and Negroids. DNA sequencing of limited regions of the gene supports this conclusion. This finding does not exclude, however, that a heterogeneity of the O allele may be revealed by a more extensive analysis.

    Individuals with blood group O have a higher bleeding risk than non-O blood groups. This could be explained by the lower levels of FVIII and von Willebrand Factor (VWF) levels in O individuals. We investigated the relationship between blood groups, thrombin generation (TG), prothrombin activation and thrombin inactivation. Plasma levels of VWF, FVIII, antithrombin, fibrinogen, prothrombin and α2Macroglobulin (α2M) levels were determined. TG was measured in platelet rich (PRP) and platelet poor plasma (PPP) of 217 healthy donors and prothrombin conversion and thrombin inactivation were calculated. VWF and FVIII levels were lower (75% and 78%) and α2M levels were higher (125%) in the O group. TG is 10% lower in the O group in PPP and PRP. Less prothrombin was converted in the O group (86%) and the thrombin decay capacity was lower as well. In the O group, α2M plays a significantly larger role in the inhibition of thrombin (126%). In conclusion, TG is lower in the O group due to lower prothrombin conversion, and a larger contribution of α2M to thrombin inactivation. The former is unrelated to platelet function because it is similar in PRP and PPP, but can be explained by the lower levels of FVIII.

    The clinical outcome of falciparum malaria in endemic areas is influenced by erythrocyte polymorphisms including the ABO blood groups. Studies have reported association of ABO blood group to resistance, susceptibility, and severity of P. falciparum malaria infection. Individuals with blood group "A" have been found to be highly susceptible to falciparum malaria whereas blood group "O" is said to confer protection against complicated cases. We analyzed samples from 293 young children less than six years old with malaria in the Korle-Bu Teaching Hospital in Accra, Ghana. It was observed that group O was present in about 16.1% of complicated cases weighed against 40.9% of uncomplicated controls. Individuals with complicated malaria were about twice likely to be of blood groups A and B compared to group O (A versus O, OR = 1.90, 95% CI = 1.59-2.26, P Blood group O participants with complicated diseases had low parasitaemia compared to the other blood groups (P blood group O individuals a survival advantage over the other groups in complicated malaria as suggested.

    Data on blood group phenotypes are important for blood transfusion programs, for disease association and population genetics studies. This study aimed at reporting the phenotypic and allelic distribution of ABO and Rhesus (Rh) groups in various ethnolinguistic groups in the Cameroonians. We obtained ABO and Rhesus blood groups and self-identified ethnicity from 14,546 Cameroonian students. Ethnicity was classified in seven major ethnolinguistic groups: Afro-Asiatic, Nilo-Saharan, Niger-Kordofanian/West Atlantic, Niger-Kordofanian/Adamawa-Ubangui, Niger-Kordofanian/Benue-Congo/Bantu/Grassfield, Niger-Kordofanian/Benue-Congo/Bantu/Mbam and Niger-Kordofanian/Benue-Congo/Bantu/Equatorial. ABO allelic frequencies were determined using the Bernstein method. Differences in phenotypic distribution of blood groups were assessed using the chi-square test; a P value blood groups O, A, B and AB were 48.62%, 25.07%, 21.86% and 4.45%, respectively. Rhesus-positive was 96.32%. The allelic frequencies of O, A and B genes were 0.6978, 0.1605 and 0.1416, respectively. Phenotypic frequencies of the blood groups in the general study population and in the different ethnolinguistic groups were in agreement with Hardy-Weinberg equilibrium expectations (P > 0.05). The frequencies of O, A, and B blood phenotypes were significantly lower, respectively, in the Nilo-Saharan group (P = 0.009), the Niger-Kordofanian/Benue-Congo/Bantu groups (P = 0.021) and the Niger-Kordofanian/West-Atlantic group. AB blood group was most frequent in the Niger-Kordofanian/Adamawa-Ubangui group (P = 0.024). Our study provides the first data on ethnic distribution of ABO and Rhesus blood groups in the Cameroonian population and suggests that its general profile is similar to those of several sub-Saharan African populations. We found some significant differences in phenotypic distribution amongst major ethnolinguistic groups. These data may be important for blood donor recruitment policy and blood transfusion

    Full Text Available Dementia includes a group of neuro-degenerative disorders characterized by varying degrees of cognitive impairment. Recent data indicates that blood group AB is associated with impaired cognition in elderly patients. To date there are no large-scale studies that have examined the relationship between ABO blood group and dementia-related disorders in detail.We used data from the SCANDAT2 database that contains information on over 1.6 million blood donors from 1968 in Sweden and 1981 from Denmark. The database was linked with health outcomes data from nationwide patient and cause of death registers to investigate the relationship between blood groups and risk of different types of dementia. The incident rate ratios were estimated using log-linear Poisson regression models.Among 1,598,294 donors followed over 24 million person-years of observation we ascertained 3,615 cases of Alzheimer's disease, 1,842 cases of vascular dementia, and 9,091 cases of unspecified dementia. Overall, our study showed no association between ABO blood group and risk of Alzheimer's disease, vascular dementia or unspecified dementia. This was also true when analyses were restricted to donors aged 70 years or older except for a slight, but significantly decreased risk of all dementia combined in subjects with blood group A (IRR, 0.93; 95% confidence interval [CI], 0.88-0.98, compared to those with blood group O.Our results provide no evidence that ABO blood group influences the risk of dementia.

    A much larger sample (N = 2369) was used to evaluate a previously reported distribution of the A, AB and B blood group phenotypes in rhesus and cynomolgus macaques from six different regional populations. These samples, acquired from 15 different breeding and research facilities in the United States, were analyzed using a real-time quantitative polymerase chain reaction (qPCR) assay that targets single nucleotide polymorphisms (SNPs) responsible for the macaque A, B and AB phenotypes. The frequency distributions of blood group phenotypes of the two species differ significantly from each other and significant regional differentiation within the geographic ranges of each species was also observed. The B blood group phenotype was prevalent in rhesus macaques, especially those from India, while the frequencies of the A, B and AB phenotypes varied significantly among cynomolgus macaques from different geographic regions. The Mauritian cynomolgus macaques, despite having originated in Indonesia, showed significant (P ≪ .01) divergence from the Indonesian animals at the ABO blood group locus. Most Mauritian animals belonged to the B blood group while the Indonesian animals were mostly A. The close similarity in blood group frequency distributions between the Chinese rhesus and Indochinese cynomolgus macaques demonstrates that the introgression between these two species extends beyond the zone of intergradation in Indochina. This study underscores the importance of ABO blood group phenotyping of the domestic supply of macaques and their biospecimens. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Since Helicobacter pylori has been established as the main etiological factor in this disease, controversies about the associations of the ABO and Lewis blood group phenotypes and secretor and nonsecretor phenotypes in relation to susceptibility towards infection by this bacillus have been presented. The aim of this study was to verify the frequencies of ABO and Rhesus (Rh blood groups in H. pylori seropositive symptomatic patients. The study included (n = 1108 patients with dyspepsia symptoms referred from an outpatient clinic in Erbil city for investigation. Age, sex, and residency were recorded as a routine laboratory framework. Patients underwent SD Bioline (Standard Diagnostics Inc, Kyonggi-do, South Korea and enzyme-linked immunosorbent assay serologic tests for H. pylori. ABO blood group phenotypes were determined by a standard hemagglutination test. Results showed that 64.8% of patients (n = 718/1108 were seropositive for H. pylori infection, and (35.2% (n = 390/1108 were seronegative. Of the seropositive patients, 40.8% (n = 293/718 were male and 59.2% (n = 425/718 were female; while of the seronegative patients, 46.7% (n = 182/390 were male and 53.3% (n = 208/390 were female. The mean age for seropositives and seronegatives was (38.0 ± 14.6 years and (37.6 ± 15.7 years respectively. The frequency of the ABO and Rh-positive (Rh+ blood groups among seropositive patients was (A = 32.0%, B = 19.5%, AB = 6.7%, O = 41.8%, and Rh+ = 92.5% and was (A = 32.3%, B = 28.2%, AB = 8.0%, O = 31.5%, and Rh+ = 92.5% in seronegatives.

    Hemoglobinopathies are a group of inherited disorders of hemoglobin synthesis. It could be formed a fatal scenario in concern of lacking of actual information. Beside this, ABO and Rh blood grouping are also important matter in transfusion and forensic medicine and to reduce new born hemolytic disease (NHD). The spectrum and prevalence of various hemoglobinopathies, ABO and rhesus (Rh) blood groups was screened among patients who visited B.S. Medical College and Hospital, Bankura, West Bengal, India. This study was carried out on 958 patients of different ages ranging from child to adults from January to June 2011. High-performance liquid chromatography (HPLC), complete blood count (CBC) and hemagglutination technique were performed for the assessment of abnormal hemoglobin variants, ABO and Rh blood groups, respectively. Results from this study had been shown that there was high prevalence of hemoglobinpathies (27.35%) where β-thalassemia in heterozygous state occurred more frequent than other hemoglobinopathies. Out of 958 patients, 72.65% were HbAA and 27.35% were hemoglobinopathies individuals where 17.64% β-thalassemia heterozygous, 2.92% β-thalassemia homozygous, 3.86% HbAE, 1.15% HbAS trait, 1.25% HbE-β thalassemia trait and 0.52% HbS-β thalassemia trait were found. No incidence of HbSS, HbSC, HbCC, HbD and other variants of hemoglobinpathies were observed. The gene frequencies with respect to ABO systems had been shown as O > B > A > AB. Blood group O was the highest (35.8%) and the least percentage distribution was blood group AB (6.68%). Rhesus positive (Rh+) were 97.7%, while the remaining was 2.3% Rhesus negative (Rh-). The frequencies of A(+), B(+), AB(+,) and O(+) blood groups were 22.44%, 33.61%, 6.58%, and 35.07%, respectively. Remarkable percentages of hemoglobinopathies were prevalent from the present study. An extensive screening of the population is needed to assess the prevalence of hemoglobinopathies, which will help in identification of

    The present study aims to investigate and to reveal the relationship between ABO blood groups and body mass index (BMI) and obesity among Turkish seafarers by using the health examination reports data obtained from 2009 to 2016. The data on age, gender, weight, height and blood groups obtained from 298,247 medical examination reports of Turkish seafarers were used with the official permission of Directorate General of Health for Border and Coastal Areas. Only 116,871 reports included blood group data. Regression and analysis of variance (ANOVA) tests were performed to survey relationship between variables. The results of the study were compared with other studies in the related literature. It has been revealed that AB Rh (-) group was associated the highest mean BMI value (mean: 25.952). It is suggested that seafarers with AB Rh (-) blood group, who have the highest mean BMI value, should pay special attention to their weight.

    Aim of our study was to evaluate distribution of ABO and Rh blood type groups in children after hip surgery regarding transfusion administration and fever presence. Four types of ABO blood groups (A; B; AB; O) and 2 types of Rh blood groups (Rh+; Rh-) were evaluated in group with administered transfusion (tr+) and without given transfusion (tr-); and in group with fever (fev+) and without fever (fev-), in 146 children after hip surgery. Tr+ and fev+ groups were divided into 3 groups (0-24h; 25-48h; 49-72h): for tr+ group (Group 1, Group 2, Group 3), and for fev+ group (Group A, Group B, Group C). AB blood group significantly decreased in Group 1 (χ2= 6.44; pblood group in Group 3 in tr+ group (χ2= 7.68; pblood group significantly increased in Group 3 in tr+ group (χ2= 9.96; pblood group significantly decreased in Groups B (χ2= 12.2; pblood group significantly increased in Group C (χ2= 34.4; pgroup. Administration of transfusion and fever onset in pediatric patients undergoing surgical correction of the hip is not influenced by the ABO and Rh blood groups system in humans. There is correlation between distribution of ABO blood groups with the time of transfusion administration and fever onset in children after hip surgery.

    The aim of this study was to investigate the prevalence of hepatitis B, hepatitis C, HIV and syphilis infections in blood donors referred to Tehran Blood Transfusion Center (TBTC), and determine any association between blood groups and blood- borne infections between the years of 2005 and 2011. This was a retrospective study conducted at TBTC. All of the donor serum samples were screened for HBV, HCV, HIV and syphilis by using third generation ELISA kits and RPR test. Initial reactive samples were tested in duplicate. Confirmatory tests were performed on all repeatedly reactive donations. Blood group was determined by forward and reverse blood grouping. The results were subjected to chi square analysis for determination of statistical difference between the values among different categories according to SPSS program. Overall, 2031451 donor serum samples were collected in 2005-2011. Totally, 10451 were positive test for HBV, HCV, HIV and syphilis. The overall seroprevalence of HBV, HCV, HIV, and syphilis was 0.39%, 0.11%, 0.005%, and 0.010%, respectively. Hepatitis B and HIV infections were significantly associated with blood group of donors (P blood group "A" and percentage of HBs Ag was lower in donors who had blood group O. There was no significant association between Hepatitis C and syphilis infections with ABO and Rh blood groups (P>0.05). Compared with neighboring countries and the international standards, prevalence of blood-borne infections is relatively low.

    Erythrocyte polymorphisms associated with a survival advantage to Plasmodium falciparum infection have undergone positive selection. There is a predominance of blood group O in malaria-endemic regions, and several lines of evidence suggest that ABO blood groups may influence the outcome of P. falciparum infection. Based on the hypothesis that enhanced innate clearance of infected polymorphic erythrocytes is associated with protection from severe malaria, we investigated whether P. falciparum-infected O erythrocytes are more efficiently cleared by macrophages than infected A and B erythrocytes. We show that human macrophages in vitro and mouse monocytes in vivo phagocytose P. falciparum-infected O erythrocytes more avidly than infected A and B erythrocytes and that uptake is associated with increased hemichrome deposition and high molecular weight band 3 aggregates in infected O erythrocytes. Using infected A1, A2, and O erythrocytes, we demonstrate an inverse association of phagocytic capacity with the amount of A antigen on the surface of infected erythrocytes. Finally, we report that enzymatic conversion of B erythrocytes to type as O before infection significantly enhances their uptake by macrophages to observed level comparable to that with infected O wild-type erythrocytes. These data provide the first evidence that ABO blood group antigens influence macrophage clearance of P. falciparum-infected erythrocytes and suggest an additional mechanism by which blood group O may confer resistance to severe malaria.

    Both serology-based and genetic studies have reported an association between pancreatic cancer risk and ABO blood groups. We have investigated this relationship in a cohort of pancreatic cancer patients from Western Norway (n = 237) and two control materials (healthy blood donors, n = 379; unselected hospitalized patients, n = 6149). When comparing patient and blood donor ABO allele frequencies, we found only the A 1 allele to be associated with significantly higher risk for pancreatic ductal adenocarcinoma (PDAC) (23.8% vs. 17.9%; OR = 1.43, P = 0.018). Analyzing phenotypes, blood group A was more frequent among PDAC cases than blood donors (50.8% vs. 40.6%; OR = 1.51, P = 0.021), an enrichment fully explained by the A 1 subgroup. Blood group O frequency was lower in cases than in blood donors (33.8% vs. 42.7%; OR = 0.69, P = 0.039). This lower frequency was confirmed when cases were compared to hospitalized patients (33.8% vs. 42.9%; OR = 0.68, P = 0.012). Results for blood group B varied according to which control cohort was used for comparison. When patients were classified according to surgical treatment, the enrichment of blood group A was most prominent among unresected cases (54.0%), who also had the lowest prevalence of O (28.7%). There was a statistically significant better survival (P = 0.04) for blood group O cases than non-O cases among unresected but not among resected patients. Secretor status did not show an association with PDAC or survival. Our study demonstrates that pancreatic cancer risk is influenced by ABO status, in particular blood groups O and A 1 , and that this association may reflect also in tumor resectability and survival. © 2017 The Authors.

    Full Text Available Inhaled nitric oxide (iNO reduces death or need for extracorporeal membrane oxygenation (ECMO in infants with persistent pulmonary hypertension of the newborn (PPHN. However, the response to iNO is variable and only 50-60% of infants demonstrate a response to iNO. It is not known why only some infants respond to iNO. Adults and children with blood groups B or AB do not respond as well to iNO as those with blood groups O/A.To determine if blood group was associated with iNO response in newborn infants, a retrospective medical record review was done of infants admitted to a regional NICU from 2002-9 with a diagnosis of PPHN. Data were collected during the first twelve hours post-initiation of treatment. Of 86 infants diagnosed with PPHN, 23 infants had blood group A [18 received iNO], 21 had group B [18 with iNO], 40 had group O [36 with iNO], and 2 had group AB [both received iNO]. Change in PaO(2/FiO(2 was less in infants with blood group A, of whom less than half were responders (ΔPaO(2/FiO(2>20% at 12 h versus 90% of infants with either O or B. Race, sex, birth weight, gestational age, Apgar scores at 1 and 5 minutes, and baseline PaO(2/FiO(2 were similar among groups. Outcomes including need for ECMO, death, length of ventilatory support, length of iNO use, and hospital stay were statistically not different by blood groups.Our results indicate that blood group influences iNO response in neonates. We hypothesize that either there is genetic linkage of the ABO gene locus with vasoregulatory genes, or that blood group antigens directly affect vascular reactivity.

    Backround: ABO and Rhesus (Rh) blood group antigens are hereditary characters and are useful in population genetic studies, in resolving medico-legal issues and more importantly for the immunologic safety of blood during transfusion. This study is aimed to determine the distribution pattern of the ABO and Rh blood groups among blood donors in Kumaon region of Uttarakhand and compare it with other data from similar studies within the India and all over the world. It is a retrospective study carried out at blood bank of Shushila Tewari Hospital of Government Medical College, Haldwani from January 2012 to December 2013. The study was conducted on 12,701 blood donors. ABO and Rh typing was done using slide agglutination method with antisera ABO and Rh (Tulip diagnostics ltd). Doubtful cases were confirmed by tube agglutination method and reverse grouping using known pooled A and B cells. The age group and sex of donors, frequency of ABO and Rh blood groups were reported in simple percentages. The predominant donors belonged to age group between 18-35years (84.28%). Male donors were more than female donors, ratio being 352:1. Replacement donors (99.71%) were much more than voluntary donors (0.91%). The most common blood group was B (32.07%) and least common being AB (10.53%). Blood group 'O' and 'A' had same frequency. The prevalence of Rhesus positive and negative distribution in the studied population was 94.49% and 5.51% respectively. Blood group frequency with respect to ABO and Rhesus positive was found to be shown by formula B> O>A >AB. The frequency for ABO and Rhesus negative was given by the formula B>A>O>AB. Knowledge of frequencies of the different blood groups is very important for blood banks and transfusion service policies that could contribute significantly to the National Health System.

    To evaluate if ABO blood group and Rh factor have an effect on retinal and choroidal thickness. This study was designed prospectively. Retinal nerve fiber layer, retinal, and choroidal thicknesses were measured with spectral-domain optical coherence tomography. Retinal and choroidal thickness measurements (one subfoveal, three temporal, and three nasal) were obtained at 500-μm intervals up to 1500 μm with the caliper system. In this study, 109 male and 151 female, 260 individuals in total were included. There were 125 subjects in group A, 29 in group B, 34 in group AB, and 72 in group O. Rh factor was positive in 194 subjects and negative in 66. There was no significant difference between the groups regarding age (p = 0.667). The groups did not show any statistical difference in retinal nerve fiber layer thickness. There was significant difference found for mean retinal thickness at temporal 1000 μm when four groups were compared (p = 0.037). No statistically significant difference was detected for the remaining retinal and choroidal sectoral regions. The groups did not statistically significantly differ concerning Rh factor (p > 0.05). Although we found a significant difference in retinal thickness in the temporal retina between group B with group A and group O, we suggest that both blood group and Rh factor have no effect on retinal and choroidal thickness.

    Several studies have demonstrated that non-O blood groups subjects present an increased VTE risk as compared to those carrying O blood group. The aim of this study was to investigate the ABO blood groups influence on factor VIII (FVIII) activity, von Willebrand factor (VWF), and ADAMTS13 plasma levels in patients undergoing hemodialysis (HD). Patients undergoing HD (N=195) and 80 healthy subjects (control group) were eligible for this cross-sectional study. The ABO blood group phenotyping was performed by the reverse technique. FVIII activity was measured through coagulometric method, and VWF and ADAMTS13 antigens were assessed by ELISA. FVIII activity and VWF levels were significantly higher and ADAMTS13 levels was decreased in HD patients, as compared to healthy subjects (P blood groups showed a significant increase in FVIII activity (P = 0.001) and VWF levels (P blood group. However, no significant difference was observed in ADAMTS13 levels (P = 0.767). In the control group, increased in FVIII activity (P = 0.001) and VWF levels (P = 0.002) and decreased in ADAMTS13 levels (P = 0.005) were observed in subjects carrying non-O blood groups as compared to carriers of O blood group.Our data confirmed that ABO blood group is an important risk factor for increased procoagulant factors in plasma, as FVIII and VWF. Admitting the possible role of kidneys in ADAMTS13 synthesis or on its metabolism, HD patients were not able to increase ADAMTS13 levels in order to compensate the increase of VWF levels mediated by ABO blood groups. Considering that non-O blood groups constitute a risk factor for thrombosis, it is reasonable to admit that A, B and AB HD patients need a careful and continuous follow-up in order to minimize thrombotic events.

    Background. Relationship between blood groups and dermatologic diseases remains controversial and was not yet fully elucidated nor explained clearly. The aim of this study was to examine if any relation exists between different types of pemphigoid diseases and ABO blood group. Methods. In this case-control study, 159 pemphigoid patients and 152 healthy matched-controls were evaluated. All blood group (including Rh status) data for the study was obtained from the hospital medical records. Statistical comparisons were completed with chi-square test and logistic regression. Results. Blood group "O" was found in 32.9% of patients and 38.2% of control group. Blood group "A" was found among 30.8% of patients and 34.2% of control group, while group "B" was reported in 27.4% of cases and 21.1% of controls and "AB" was identified among 8.9% of patients and 6.6% of control group. 84.9% of patients were Rh positive, while in the control group 86.2% of patients were Rh positive. No significant differences were found regarding ABO blood groups (P = 0.46) or Rh (P = 0.76) between pemphigoid patients and control group. Also, older females had the higher risk of developing bullous pemphigoid. Conclusion. We found no relationship between ABO blood groups and pemphigoid disease.

    Characterization of the ABO blood group at the phenotype and genotype levels is clinically essential for transfusion, forensics, and population studies. This study elucidated ABO phenotypes and genotypes, and performed an evaluation of their distribution in individuals from the western region of Saudi Arabia. One-hundred and seven samples underwent standard serological techniques for ABO blood group phenotype analysis. ABO alleles and genotypes were identified using multiplex polymerase chain reaction, and electrophoretic analysis was performed to evaluate the highly polymorphic ABO locus. A phenotype distribution of 37.4%, 30.8%, 24.3%, and 7.5% was found for blood groups O, A, B, and AB respectively in our study cohort. Genotype analysis identified 10 genotype combinations with the O01/O02 and A102/O02 genotypes being the most frequent with frequencies of 33.6% and 14.95%, respectively. Common genotypes such as A101/A101 , A101/A102 , A101/B101 , B101/B101 , and O01/O01 were not detected. Similarly, the rare genotypes, cis-AB01/O02 , cis-AB01/O01 , and cis-AB01/A102 were not found in our cohort. The most frequently observed allele was O02 (35.98%) followed by the A102 allele (17.76%). Furthermore, our findings are discussed in reference to ABO allele and genotype frequencies found in other ethnic groups. The study has a significant implication on the management of blood bank and transfusion services in Saudi Arabian patients.

    The present study deals with anthropogenetic profile of the Arab speaking population of the Beni Mellal region which separates areas inhabited by Mid-Atlas Berbers from those inhabited by Soth-Morroccan Arabs. The study of blood groups ABO, Rhesus, Ss,and Duffy was conducted on 131 individuals. The result shows that this population has the highest frequencies of the FyO allele (0.860) and s allele (0.524) in comparison to all Arab and Berber populations of North Africa and the Middle East. However genetic distances estimated on the basis of these four markers reveal that the population of Beni Mellal and another in the Beni Hlal region are in the same sub-cluster with populations from the Middle East. This may be attributed to the Oriental Arab ( M achrek ) origin of these two Moroccan Arab populations. (author)

    At the ABCC clinic in Hiroshima 1330 subjects were investigated as to serum pepsin levels over a four month period. The normal mean values compared well with those reported for a United States population using a similar technique. There appeared to be no significant change in serum pepsin level with age, and no difference could be detected among individuals of the ABO blood groups. No relationship was found between serum pepsin level and exposure to ionizing radiation. Patients with gastric and duodenal ulcers had mean levels which were higher than normal mean values, while patients with leukemia had lower than normal mean levels. Patients with gastric polyps and gastric cancer had normal mean values. It is believed that the relation of serum pepsin activity to cancer of the stomach is not settled and deserves further investigation. 23 references, 2 figures, 4 tables.

    The authors report a simple, rapid, sensitive and accurate solid phase radioimmunoassay (SPRIA) method which has been improved. The research included the tests of its methodological parameters, sensitivity, accuracy, and the studies on its applications to the detection of blood group substances in varied forensic biological materials. The coefficient variation of intra-assay was 5.6%, and that of inter-assay was 10.15%. As to its applications to the forensic serology, the ABO blood groups of human bloodstain, hair follicular tissues and salivary stains had been tested and the results were satisfying. Later, 50 unknown type bloodly samples had been blind tested. The judging level used to identify the positive and negative wells was 800 cpm, that meant, if the radioactive count of a well were over 800 cpm, it was determined as a positive well, if that of a well were below 800 cpm, it was negative well. As SPRIA is a method of micro-determination which can micro-test the blood group antigens contained in varied forensic biological materials, it should has a good future of its applications to the forensic medicine fields

    To determine the frequency of ABO blood group and Rhesus (Rh) D antigen in the females of "District" Peshawar, Khyber Pakhtunkhwa Province, Pakistan. This cross-sectional study was conducted on 429 women having pregnancy induced hypertension, admitted in the three teaching hospitals of Peshawar, over a period of one year. Blood sample was collected from each subject after taking informed consent. The antigen antibody agglutination slide test for "blood grouping (ABO)" and RhD factors was done by using IgM and IgG monoclonal reagents. The antisera used were from Biolaboratory, USA. Data was analyzed for percentage calculation. The blood group distribution was 134 (31.2%), 43 (10.1%), 116 (27%), 136 (31.7%) for blood groups A, AB, O and B, respectively. Subjects having blood group B was slightly more dominant, followed by A and O, while blood group AB was rare in these females. Blood group A Rh negative is more in female 12 (37.5%) followed by group O 10 (31.3%), group B 09 (28.1%) and group AB 01 (3.1%). Frequency of "Rh-positive blood group" is B, A, O and AB, whereas the frequency of the most common Rh-negative blood group are A, O, B and AB respectively. The determination of the frequency of blood groups in the region would not only help in blood transfusion services, but also reduce the risk of erythroblastosis foetalis in the neonates.

    The ABO blood group system was the significant element for forensic serological examination of blood and body fluids in the past before the wide adaptation of DNA typing. A significant proportion of individuals (80%) are secretors, meaning that antigens present in the blood are also found in other body fluids such as saliva. Absorption inhibition is one such method that works by reducing strength of an antiserum based on type and amount of antigen present in the stains. To check the efficacy of identifying the blood group antigens in saliva and to know the secretor status using absorption inhibition method among southern Rajasthan population. Blood and saliva samples were collected from 80 individuals comprising 20 individuals in each blood group. The absorption inhibition method was used to determine the blood group antigens in the saliva and then the results were correlated with the blood group of the collected blood sample. The compiled data was statistically analysed using chi-square test. Blood groups A & O revealed 100% secretor status for both males and females. While blood groups B and AB revealed 95% secretor status. Secretor status evaluation of the ABO blood group antigen in saliva using absorption inhibition method can be a useful tool in forensic examination.

    Recent studies have reported that the ABO gene can affect circulating expression levels of soluble intercellular adhesion molecule 1 (sICAM-1) and soluble P-selectin (sP-selectin) in Caucasians. However, several factors may affect the association, including the distribution and variations of the ABO gene, ethnic diversity and the inflammatory response status. The aim of the present study was to investigate this issue in Asian subjects of various blood groups. A total of 800 blood samples were randomly selected from healthy blood donors. The ABO blood groups were examined using standard serological tests, and ABO genotypes of group A and group AB specimens were analyzed. Plasma concentrations of sICAM-1 and sP-selectin were detected by standard enzyme-linked immunosorbent assays. In healthy Chinese individuals, blood group A was detected to be significantly associated with lower circulating expression levels of sICAM-1 and sP-selectin, compared with group O. Individuals with ≥1 A1 allele had significantly lower expression levels of sICAM-1 and sP-selectin compared with all other ABO groups. The data indicate the significant association of ABO blood group antigens with sICAM-1 and sP-selectin expression levels in a healthy Chinese population, independent of the specific variations and distributions of ABO blood groups among ethnic populations. This result provides evidence for the previously unidentified role of ABO blood group antigens in the regulation of the inflammatory adhesion process. Accordingly, it can be proposed that ABO blood groups may require consideration when soluble adhesion molecules are identified as predictors for cardiovascular disease.

    Preeclampsia (PE) is a major cause of maternal and neonatal morbidity and mortality. There is a genetic component in the development of PE with estimated heritability around 0.47. Several studies have investigated the association between maternal ABO blood groups (OMIM 110300) and risk of PE, with contradictory results have emerged. Considering that there is no study in this filed from Iranian population, the present case-control study was carried out at Shiraz (south-west Iran). In this study 331 women; 121 pregnant with PE and 210 normotensive pregnant women were included. Using blood group O (for ABO blood groups) or Rh+ (for Rh blood groups) as a reference, odds ratios (ORs) and its 95% confidence intervals (95% CI) of PE risk were estimated from logistic regression analysis. Although the A (OR = 0.67, 95% CI = 0.39-1.17, P = 0.165), B (OR = 0.86, 95% CI = 0.48-1.53, P = 0.615) and AB (OR = 1.14, 95% CI = 0.37-3.45, P = 0.812) phenotypes showed lower risks compared with the O blood group, statistical analysis indicated that there was no significant association between ABO phenotypes and risk of PE. The frequency of Rh- phenotype was higher among PE patients compared with the control group. However, the association was not significant (OR = 1.79, 95% CI = 0.69-4.65, P = 0.229). Adjusted ORs for age of participants and parity did not change the above-mentioned associations. Our present findings indicate that there is no association between ABO and Rh blood groups and risk of PE in Iranian population.

    Using the highly sensitive immunohistochemical staining method EnVision+, which employs a dextran polymer reagent for the secondary antibody, the detection of the ABH antigens was attempted in the oral squamous epithelium. This new technique uses monoclonal antibody as a primary antibody and it takes about three hours for staining. The time is much shorter than conventional absorption-elution testing or absorption-inhibition testing for the determination of ABO blood grouping. Secretor saliva samples were stained at strong intensity by the antibody, which corresponded to its blood group and anti-H. On the one hand, nonsecretor saliva samples were stained at strong intensity only by the antibody that corresponded to its blood group, and at weak intensity only by anti-H. Since human oral squamous epithelium antigens were stained specifically by this method, we can examine the ABO blood group of saliva samples and perform cytodiagnosis at the same time. Our research suggested that the EnVision+ Method is a useful technique for ABO blood grouping of saliva in forensic cases.

    The association between ABO blood group and the risk of esophageal carcinoma (EC) in previously published studies is uncertain and conflicting. The aim of the current study was to determine the correlation of ABO blood group with EC risk via a case-control study and meta-analysis. We performed a population-based case-control study of 3,595 cases and 41,788 controls in Chinese population to evaluate the association between ABO blood group and EC risk. Then, a comprehensive meta-analysis combining our original data and previously published data was conducted to clearly discern the real relationship. The strength of association was measured by odds ratios (ORs) with 95% confidence intervals (CI). In our case-control study, the risk of EC in blood group B was significantly higher than that in non-B groups (A, O, and AB) (OR = 1.15, 95% CI 1.09-1.21). Compared with non-O groups (A, B, and AB), individuals with blood group O demonstrated a reduced risk of EC (OR = 0.90, 95% CI 0.85-0.94). The meta-analysis also indicated that blood group B was associated with significantly higher EC risk (OR = 1.20, 95% CI 1.10-1.31), and people with blood group O had a decreased EC risk (OR = 0.94, 95% CI 0.90-0.99). Neither the case-control study nor the meta-analysis produced any significant association of blood group A or AB with EC risk. Results from our case-control study and the followed meta-analysis confirmed that there was an increased risk of EC in blood group B individuals, whereas a decreased risk of EC was observed in blood group O individuals.

    Full Text Available Objective. To determine the frequency and distribution of ABO and Rh (D antigens and, additionally, investigate gene diversity and the structure of Mexican populations. Materials and Methods. Blood groups were tested in 271,164 subjects from 2014 to 2016. The ABO blood group was determined by agglutination using the antibodies anti-A, Anti-B, and Anti-D for the Rh factor, respectively. Results. The overall distribution of ABO and Rh (D groups in the population studied was as follows: O: 61.82%; A: 27.44%; B: 8.93%; and AB: 1.81%. For the Rh group, 95.58% of people were Rh (D, and 4.42% were Rh (d. Different distributions of blood groups across regions were found; additionally, genetic analysis revealed that the IO and ID allele showed an increasing trend from the north to the center, while the IA and Id allele tended to increase from the center to the north. Also, we found more gene diversity in both loci in the north compared with the center, suggesting population structure in Mexico. Conclusion. This work could help health institutions to identify where they can obtain blood products necessary for medical interventions. Moreover, this piece of information contributes to the knowledge of the genetic structure of the Mexican populations which could have significant implications in different fields of biomedicine.

    This investigation focused on possible relationships between skin cancers and ABO/Rh blood groups. Between January 2005 and December 2012, medical data of 255 patients with skin cancers who were admitted to Kayseri Training and Research Hospital, Radiation Oncology and Plastic Surgery Outpatient Clinics were retrospectively analyzed. Blood groups of these patients were recorded. The control group consisted of 25701 healthy volunteers who were admitted to Kayseri Training and Research Hospital, Blood Donation Center between January 2010 and December 2011. The distribution of the blood groups of the patients with skin cancers was compared to the distribution of ABO/Rh blood groups of healthy controls. The association of the histopathological subtypes of skin cancer with the blood groups was also investigated. Of the patients, 50.2% had A type, 26.3% had O type, 16.1% had B type, and 7.5% had AB blood group with a positive Rh (+) in 77.3%. Of the controls, 44.3% had A type, 31.5% had 0 type, 16.1% had B type, and 8.1% had AB blood group with a positive Rh (+) in 87.8%. There was a statistically significant difference in the distribution of blood groups and Rh factors (A Rh (-) and 0 Rh positive) between the patients and controls. A total of 36.8% and 20.4% of the patients with basal cell carcinoma (BCC) had A Rh (+) and B Rh (+), respectively, while 39.2% and 27.6% of the controls had A Rh (+) and B Rh (+), respectively. A significant relationship was observed between the patients with BCC and controls in terms of A Rh (-) (p=0.001). Our study results demonstrated that there is a significant relationship between non-melanoma skin cancer and ABO/Rh factors.

    A number of automated devices for pretransfusion testing have recently become available. This study evaluated the Immucor Galileo System, a fully automated device based on the microplate hemagglutination technique for ABO/Rh (D) determinations. Routine ABO/Rh typing tests were performed on 13,045 samples using the Immucor automated instruments. Manual tube method was used to resolve ABO forward and reverse grouping discrepancies. D-negative test results were investigated and confirmed manually by the indirect antiglobulin test (IAT). The system rejected 70 tests for sample inadequacy. 87 samples were read as "No-type-determined" due to forward and reverse grouping discrepancies. 25 tests gave these results because of sample hemolysis. After further tests, we found 34 tests were caused by weakened RBC antibodies, 5 tests were attributable to weak A and/or B antigens, 4 tests were due to mixed-field reactions, and 8 tests had high titer cold agglutinin with blood qualifications which react only at temperatures below 34 degrees C. In the remaining 11 cases, irregular RBC antibodies were identified in 9 samples (seven anti-M and two anti-P) and two subgroups were identified in 2 samples (one A1 and one A2) by a reference laboratory. As for D typing, 2 weak D+ samples missed by automated systems gave negative results, but weak-positive reactions were observed in the IAT. The Immucor Galileo System is reliable and suited for ABO and D blood groups, some reasons may cause a discrepancy in ABO/D typing using a fully automated system. It is suggested that standardization of sample collection may improve the performance of the fully automated system.

    Full Text Available INTRODUCTION: Erythrocytes carry apolipoprotein B on their membrane, but the determining factors of erythrocyte-bound apolipoprotein B (ery-apoB are unknown. We aimed to explore the determinants of ery-apoB to gain more insight into potential mechanisms. METHODS: Subjects with and without CVD were included (N = 398. Ery-apoB was measured on fresh whole blood samples using flow cytometry. Subjects with ery-apoB levels ≤ 0.20 a.u. were considered deficient. Carotid intima media thickness (CIMT was determined as a measure of (subclinical atherosclerosis. RESULTS: Mean ery-apoB value was 23.2% lower in subjects with increased CIMT (0.80 ± 0.09 mm, N = 140 compared to subjects with a normal CIMT (0.57 ± 0.08 mm, N = 258 (P = 0.007, adjusted P<0.001. CIMT and ery-apoB were inversely correlated (Spearman's r: -0.116, P = 0.021. A total of 55 subjects (13.6% were considered ery-apoB deficient, which was associated with a medical history of CVD (OR: 1.86, 95% CI 1.04-3.33; adjusted OR: 1.55; 95% CI 0.85-2.82. Discontinuation of statins in 54 subjects did not influence ery-apoB values despite a 58.4% increase in serum apolipoprotein B. Subjects with blood group O had significantly higher ery-apoB values (1.56 ± 0.94 a.u. when compared to subjects with blood group A (0.89 ± 1.15 a.u, blood group B (0.73 ± 0.1.12 a.u. or blood group AB (0.69 ± 0.69 a.u. (P-ANOVA = 0.002. CONCLUSION: Absence or very low values of ery-apoB are associated with clinical and subclinical atherosclerosis. While serum apolipoprotein B is not associated with ery-apoB, the ABO blood group seems to be a significant determinant.

    Hepatitis B and HIV infection are two viral infections that represent real global public health problems. In order to improve their management, some hypotheses suggest that genetic predispositions like ABO and Rh blood groups would influence the occurrence of these diseases. The aim of the present study was to examine the association between ABO and Rhesus blood groups and the susceptibility to HIV infection and hepatitis B. We conducted a cross-sectional and analytical study in a population of voluntary blood donors in the Blood Transfusion Center of Abidjan. All blood donors who donated blood between January and June 2014 were tested for HBs antigen and anti-HIV antibodies (ELISA tests) and were ABO typed. The total number of examined blood donors during this period was 45,538, of which 0.32% and 8.07% were respectively infected with HIV and hepatitis B virus. O-group donors were more infected than non-O donors. Our study is an outline concerning the search for a link between ABO and Rh blood groups and hepatitis B and HIV infection. Further studies should be conducted to confirm the interaction between these two infections and contribute to the search for new therapeutic approaches.

    We propose a new, paper-based analytical device (PAD) for blood typing that allows for the simultaneous determination of ABO and Rh blood groups on the same device. The device was successfully fabricated by using a combination of wax printing and wax dipping methods. A 1:2 blood dilution was used for forward grouping, whereas whole blood could be used for reverse grouping. A 30% cell suspension of A-cells or B-cells was used for haemagglutination on the reverse grouping side. The total assay time was 10 min. The ratio between the distance of red blood cell movement and plasma separation is the criterion for agglutination and indicates the presence of the corresponding antigen or antibody. The proposed PAD has excellent reproducibility in that the same blood groups, namely A, AB, and O, were reported by using different PADs that were fabricated on the same day (n=10). The accuracy for detecting blood group A (n=12), B (n=13), AB (n=9), O (n=14), and Rh (n=48) typing were 92%, 85%, 89%, 93%, and 96%, respectively, in comparison with the conventional slide test method. The haematocrit of the sample affects the accuracy of the results, and appropriate dilution is suggested before typing. In conclusion, this study proposes a novel method that is straightforward, time-saving, and inexpensive for the simultaneous determination of ABO and Rh blood groups, which is promising for use in developing countries.

    The relationship between ABO blood groups (BG) and risk of incidence in cancers including gynecological cancers has been widely studied, showing increased incidence risk for BG A patients. As available data are inconsistent we investigated whether BG and their anti-glycan antibodies (anti-A and anti-B) have prognostic values in gynecological cancers. We retrospectively evaluated 974 patients with gynecological cancers in three cancer centers (Switzerland and Australia) between 1974 and 2014 regarding the relationships between clinico-pathological findings and the BG. Time to disease recurrence was significantly influenced by BG in patients with ovarian (n = 282) and vulvar (n = 67) cancer. BG O or B patients showed a significantly increased risk for ovarian cancer relapse compared to A, 59% and 82%, respectively (p = 0.045; HR O vs A = 1.59 (CI 1.01-2.51) and (p = 0.036; HR A vs B = 0.55 (CI 0.32-0.96). Median time to relapse for advanced stage (n = 126) ovarian cancer patients was 18.2 months for BG O and 32.2 for A (p = 0.031; HR O vs A = 2.07 (CI 1.07-4.02)). BG also significantly influenced relapse-free survival in patients with vulvar cancer (p = 0.002), with BG O tending to have increased relapse risk compared to A (p = 0.089). Blood groups hence associate with recurrence in ovarian and vulvar cancer: women with BG O seem to have a lower ovarian cancer incidence, however are more likely to relapse earlier. The significance of the BG status as a prognostic value is evident and may be helpful to oncologists in prognosticating disease outcome and selecting the appropriate therapy.

    There is no data available on the ABO/Rh(D) frequencies in the Mauritanian population. We retrospectively analysed records of a 5-year database that contained ABO/Rh phenotype and ethnic origin of 10 116 volunteers giving blood at the national blood transfusion centre to derive the frequencies of ABO/Rh(D) groups in the Mauritanian population. The two race categories in the country and their sub-ethnic groups: the Moors (whites and black) and the black Africans (Pulhars, Soninkes and Wolof) were included in this study. Globally, group O had the highest frequency (49.10%) followed by A (28.28%), B (18.56%) and AB (4.05%). This order more common in North African populations was found in four of the five ethnic groups composing our population. Allele frequencies were, respectively, 70.20%, 17.74% and 12.04% giving the same order of O > A > B. We observed no significant variation in these frequencies between the different ethnic groups. Rhesus study showed that with a percentage of 94.23% Rh(D) positive is by far the most prevalent, while Rh(D) negative is present only in 5.77% of the total population. This frequency distribution supports the mixed-race composition of the Mauritanian population. © 2011 Blackwell Publishing Ltd.

    To investigate the frequency and uniqueness of different lip print patterns, fingerprint patterns in relation to gender and ABO Rh blood groups among a semi-urban population of Sriganganagar, Rajasthan. The study was conducted on 1200 healthy volunteers aged 18-30 years. The cheiloscopic and dermatographic data of each subject were obtained and were analysed according to the Suzuki and Tsuchihashi and Henry systems of classification, respectively. Two forensic experts analyzed the patterns independently. The ABO Rh blood group was also recorded for each subject. The Chi square statistical analysis was done and tests were considered significant when p value blood group was noted as most common in both genders while least common were A- among males and AB- in females. Type II lip pattern was most predominant while the least common was Type I' in males and Type I' and Type V in females. The UL fingerprint pattern was the most common, while RL was least noted in both genders. All the fingerprint patterns showed correlation with different lip print patterns. A correlation was found between different blood groups and lip print patterns except Type I (vertical) lip pattern. A positive correlation was observed between all the blood groups and fingerprint patterns, except for RL pattern. There is an association between lip print patterns, fingerprint patterns and ABO blood groups in both the genders. Thus, correlating the uniqueness of these physical evidences sometimes helps the forensic team members in accurate personal identification or it can at least narrow the search for an individual where there are no possible data referring to the identity of the subject.

    The possibility of association between ABO blood groups and malignancy was first discussed by Anderson DE & Haas C. The association between blood group and oral cancer is least explored and hence this study was undertaken to evaluate relationship of ABO blood groups with an increased risk for oral cancer. The present study was conducted at various cancer hospitals in Kanpur. The study samples comprised 100 oral cancer patients and 50 controls with tobacco chewing habit. The information regarding the socio demographic profile, history on tobacco habits, type of oral cancer and ABO blood group profile was obtained from the case sheets of the patients. The frequency of squamous cell carcinoma was significantly higher in men (78%) than women (22%) and mostly found in the age range of 45-65 years and also consuming chewing type of tobacco. It was found that out of 100 patients, 53 were of blood group B+ve, 28 of O +ve, 16 of A+ve and 3 had the blood group AB+ve. The high potential risk of developing OSCC was more in B+ve blood group (1.96 times), and relative frequency (%) in blood group O+ve (1.64 times) than in the control group Among locations of oral cancers, squamous cell carcinoma of tongue (25%) and buccal mucosa (15%) was more common in B+ve and Carcinoma of floor of mouth (11%) was more common in O+ve blood group cases. It was found that people with blood group B+ve, followed by O+ve had increased risk of developing OSCC with most prevalent being Well Differentiated OSCC as compared to people of other blood groups. The present study reveals that there is an inherited element in the susceptibility against different types of oral cancers. The people with blood group B+ve and O+ve having tobacco chewing habits can be appraised that they are more at risk to develop oral cancer than people with other blood groups.

    Full Text Available Objective: To determine the prevalence of ABO and Rh blood groups based on the antigenic presence on the surface of red blood cells with respect to gender and calculate allele frequency of the blood groups. Globally, approximately 700 type red cell antigens have been identified till now. ABO and Rh blood groups play an important role in the process of blood transfusion, resolving certain medicolegal issues, parental testing, and various genetic studies. Methods: This study was conducted in H.N.B. Base Hospital, Srinagar, Uttarakhand, from January 2012 to December 2016. Relevant data of blood donors were collected from blood bank department of the hospital. Blood grouping was conducted using commercially available standard monoclonal antisera applying test tube and column agglutination techniques. Results: Out of 9883 individuals, 9333 (92.4% were males and 750 (7.6% were female individuals. The most common blood group found was B (31.68% and least common being AB (11.70%. The prevalence of Rhesus positive and negative distribution in the present studied population was found as 93.51% and 6.49%, respectively. Overall, male ABO group pattern found was shown by formula B > A > O > AB which was similar among Rh-positive male individuals while Rh-negative males' pattern was found as A > B = O > AB. In females, ABO group pattern was B > O > A > AB which was similar to Rh-positive female pattern while differs in Rh negative. The estimated allele frequencies were found as 0.2403, 0.2475, and 0.5122 for IA (p, IB (q, and IO (r, respectively. Conclusion: The most common blood group found among the Gharwali donors was B positive while the least common was AB negative, which plays an important contribution for making government policies to develop National Health Program.

    Since the discovery of the ABO blood group system by Karl Landsteiner in 1901, several reports have suggested an important involvement of the ABO blood group system in the susceptibility to thrombosis. Assessing that non-O blood groups in particular A blood group confer a higher risk of venous and arterial thrombosis than group O.Epidemiologic data are typically not available for all racial and ethnics groups.The purpose of this pilot study was to identify a link between ABO blood group and ischemic disease (ID) in Africans, and to analyze whether A blood group individuals were at higher risk of ischemic disease or not. A total of 299 medical records of patients over a three-year period admitted to the cardiology and internal medicine department of military hospital of Ouakam in Senegal were reviewed. We studied data on age, gender, past history of hypertension, diabetes, smoking, sedentarism, obesity, hyperlipidemia, use of estrogen-progestin contraceptives and blood group distribution.In each blood group type, we evaluated the prevalence of ischemic and non-ischemic cardiovascular disease. The medical records were then stratified into two categories to evaluate incidence of ischemic disease: Group 1: Patients carrying blood-group A and Group 2: Patients carrying blood group non-A (O, AB and B). Of the 299 patients whose medical records were reviewed, 92 (30.8%) were carrying blood group A, 175 (58.5%) had blood group O, 13 (4.3%) had blood group B, and 19 (6.4%) had blood group AB.The diagnosis of ischemic disease (ID) was higher in patients with blood group A (61.2%) than in other blood groups, and the diagnosis of non-ischemic disease (NID) was higher in patients with blood group O (73.6%) compared to other groups. In patients with blood group B or AB compared to non-B or non-AB, respectively there was no statistically significant difference in ID incidence.Main risk factor for ID was smoking (56.5%), hypertension (18.4%) and diabetes (14.3%).In our study

    To examine the association between ABO and RhD blood groups and gestational hypertensive disorders in a large population-based cohort. Cohort study. Risks of gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia, estimated by odds ratios for maternal ABO blood group and RhD status. National health registers of Sweden. All singleton deliveries in Sweden born to first-time mothers during the period 1987-2002 [total n = 641 926; any gestational hypertensive disorders, n = 39 011 (6.1%); pre-eclampsia cases, n = 29 337 (4.6%); severe pre-eclampsia cases, n = 8477 (1.3%)]. Using blood group O as a reference, odds ratios of gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia were obtained from logistic regression models adjusted for potential confounding factors. Gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia. Compared with blood group O, all non-O blood groups had modest but statistically significantly higher odds of pre-eclampsia. Blood group AB had the highest risk for pre-eclampsia (OR = 1.10, 95% CI 1.04-1.16) and severe pre-eclampsia (OR = 1.18, 95% CI 1.07-1.30). RhD-positive mothers had a small increased risk for pre-eclampsia (OR = 1.07, 95% CI 1.03-1.10). In the largest study on this topic to date, women with AB blood group have the highest risks of gestational hypertensive disorders, pre-eclampsia, and severe pre-eclampsia, whereas women with O blood group have the lowest risks of developing these disorders. Although the magnitude of increased risk is small, this finding may help improve our understanding of the etiology of pre-eclampsia. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

    To evaluate whether ABO-Rh blood groups have significance in the treatment response and prognosis in patients with non-metastatic breast cancer. We retrospectively evaluated files of 335 patients with breast cancer who were treated between 2005 and 2010. Demographic data, clinic- pathological findings, treatments employed, treatment response, and overall and disease-free survivals were reviewed. Relationships between clinic-pathological findings and blood groups were evaluated. 329 women and 6 men were included to the study. Mean age at diagnosis was 55.2 years (range: 26-86). Of the cases, 95% received chemotherapy while 70% were given radiotherapy and 60.9% adjuvant hormone therapy after surgery. Some 63.0% were A blood group, 17.6% O, 14.3% B and 5.1% AB. In addition, 82.0% of the cases were Rh-positive. Mean follow-up was 24.5 months. Median overall and progression-free survival times were 83.9 and 79.5 months, respectively. Overall and disease-free survival times were found to be higher in patients with A and O blood groups (pgroup (p=0.226). In univariate and multivariate analyses, ABO blood groups were identified as factors that had significant effects on overall and disease-survival times (p=0.011 and p=0.002). It was seen that overall and disease-free survival times were higher in breast cancer patients with A and O blood groups when compared to those with other blood groups. It was seen that A and O blood groups had good prognostic value in patients with breast cancer.

    Full Text Available ABO and Rhesus (Rh blood group antigens are hereditary characters and are useful in population genetic studies, in resolving medico-legal issues and more importantly in compatibility test in blood transfusion practice. Data on frequency distribution of ABO and Rh-D in Niger-Delta region of Nigeria are not available; hence we made an attempt to retrospectively analyze the records on the blood donors, transfusion recipients and patients attending antenatal care or some other medical interventions. Over a twenty-year period between 1986 and 2005, a total of 160,431 blood samples were grouped for ABO and Rh-D at the blood bank of the University of Benin Teaching Hospital, Benin City, Nigeria. Blood group distribution among these samples showed phenotypes A, B, AB and O as 23.72%, 20.09%, 2.97% and 53.22%, respectively. The Rh-D negative phenotype was found among 6.01% of the samples tested.

    Full Text Available Background : ABO incompatibility in maternal-fetal relationship has been shown to cause hemolytic disease of the newborn (HDNB; a survey which is not yet done in this locality. Aim: Frequency of ABO blood group maternal-fetal incompatibility, maternal iso-agglutinins, and immune agglutinins quantitation was carried out in Osogbo, Osun State, South-West of Nigeria. Settings and Designs : A total of 260 subjects comprising 130 postpartum mothers within the age range of 22-35 years having good obstetrics history and normal delivery, with their 130 neonate babies were used for the study. Materials and Methods : ABO cell and serum groupings were carried out on the subjects using standard antisera and cells with appropriate controls. Direct Coomb′s Test was carried out on neonate red cells. Antibody quantitation by double dilution on the maternal serum using red cells containing corresponding antigen to the antibody was determined. A titer, which is the reciprocal of the highest dilution showing agglutination by Indirect Coombs Test, was determined. Another batch of sera was pretreated with 2-mecarptoethanol before determining the titer. Statistical Analysis: The distribution study results obtained were compared in percentages, whereas the antibodies quantitation was expressed as titers using the mode of the titers for compariso-agglutininsn. Results and Conclusions : Thirty-eight percent (50 mothers were ABO incompatible with their babies, whereas 62% (80 mothers were compatible. The distribution of blood groups in the compatible population showed blood group O (45%; A (30%; B (20%; and AB (5%. Mothers O, A, and B carrying incompatible babies had a frequency of 24% each, whereas mothers AB had 28%. Serologist differences occur in maternal ABO antibodies of corresponding incompatible baby ABO antigens. A high incidence of ABO maternal-fetal incompatibility observed without detection of immune agglutinins is indicative of a rare incidence of HDNB due

    The association between ABO blood groups and intracranial aneurysms is not well-known. Many co-morbid factors are associated with intracranial aneurysms. Our objective was to assess the prevalence of different blood group in patients with intracranial aneurysm and to look for associations between risk factors and these groups. This retrospective study includes 1,491 cases who underwent surgical operations for intracranial aneurysms from 1993-2014. We have evaluated the information related to clinical history, ABO blood groups and associated risk factors in the patients both ruptured and unruptured intracranial aneurysms by chart review of the cases. In our study, out of 1,491 cases, the most common ABO blood groups were group O (668 cases, 44.80%) and Group A (603 cases, 40.44%), and Rh(+) in 1,319 (88.4%) and Rh(-) in 147 (11.6%). Blood Group A (43% vs. 36%) and Group B (16.2% vs. 8.6%) were significantly higher in Caucasian and African Americans respectively. However, in general population, there was no significant difference in blood groups between Caucasians and African Americans. Rh(-) factor was significantly higher in Caucasians compared to African Americans. Incidence of smoking was significantly higher in aneurysm patients with O group compared to others. In addition, incidence of hypercholesterolemia was significantly higher in aneurysm patients with A group compared to others. The racial disparity in the distribution of blood groups, and risk factor association with blood groups in the development of intracranial aneurysm needs to be considered. The findings from our study may be useful in identifying patients at increased risk. Further study may be required to establish the risks from multiple centers studies around the world.

    ABO and RhD blood groups are key factors affecting blood transfusion safety. The distribution of ABO and RhD blood groups varies globally, but limited data exist for ethnic distributions of these blood groups in Asian populations. We aimed to evaluate the distribution of ABO and RhD blood groups among Chinese ethnic groups. A population-based cross-sectional study. Data on ABO groups and ethnicities were obtained from the National Free Preconception Health Examination Project (NFPHEP) with participants from 220 counties of 31 provinces in China PARTICIPANTS: There were 3 832 034 participants aged 21-49 years who took part in the NFPHEP from January 2010 to December 2012 and were included in this study. The proportion of ABO and RhD blood groups among different ethnic groups was calculated. ABO and RhD blood distribution was significantly different among nine ethnic groups (Pgroups, the Yi group had more A phenotypes (34.0%), and the Manchu (33.7%) and Mongolian (33.3%) ethnic groups had more B phenotypes. The Zhuang group had the greatest proportion of O phenotypes (41.8%), followed by the Miao group (37.7%). AB phenotypes were more frequent in the Uygur ethnic group (10.6%) but lower in the Zhuang group (5.5%). Meanwhile, RhD negativity (RhD-) was greater in the Uygur group (3.3%) than in the Mongolian (0.3%) and Manchu ethnic groups (0.4%). O RhD- blood groups were more frequent in the Uygur group (0.8%) than in the other ethnic groups (0.1%-0.4%, Pblood phenotypes vary across different ethnic groups in China. The diversity in the distribution of the ABO and RhD blood groups in different ethnic groups should be considered when developing rational and evidence-based strategies for blood collection and management. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    In the past two decades the Nigerian government and religious organisations have put more emphasis on knowing the haemoglobin electrophoresis of school children and intending couples respectively. Knowledge of the distribution of blood groups and haemoglobin electrophoretic patterns among young people is vital for the prevention of haemoglobinopathies in the population and for providing effective blood banking services. Therefore, this study was designed to assess the frequency and awareness of blood group and haemoglobinphenotypes among a new set of fourth year clinical medical and dental students of the University of Ibadan, Nigeria. Data, including socio-demographics, self- reported blood group and haemoglobin phenotypes, were obtained from 155 students using a self-administered questionnaire. The ABO, Rhesus (Rh) blood groups and haemoglobin electrophoresis were determined by the tile (slide) technique and cellulose acetate at alkaline phrespectively. Only 43.9% of the participants knew their blood groups while less than a third (29.7%) knew their haemoglobin phenotypes. knowledge of both their blood groups and haemoglobin phenotypes was documented in as low as 20.6% of the respondents. The frequency of haemoglobin AA, AS, AC and. CC were 78.0%, 16.8%, 3.9% and 1.3% respectively. Similarly, the distribution of blood groups were: 0 RhD positive - 47.8%;0 RhD negative- 1.9%;ARhD positive- 21.9%; A RhD negative - 1.3%; B RhD positive - 23.2%; B RhD negative -1.3% and AB RhD positive - 2.6%. No participant was AB RhD negative. Participants who bad previously donated blood and those who were females were more likely to know their blood groups and haemoglobin phenotypes respectively (pblood groups and haemoglobin phenotypes among the medical and dental students was poor. Documentation and routine screening for haemoglobinphenotypes as well as blood grouping, accompanied by appropriate counseling should be institutionalised in Nigeriantertiary institutions.

    Full Text Available This study describes the single center experience and long-term results of ABOi kidney transplantation using a pretransplantation protocol involving immunoadsorption combined with rituximab, intravenous immunoglobulins, and triple immune suppression. Fifty patients received an ABOi kidney transplant in the period from 2006 to 2012 with a follow-up of at least one year. Eleven antibody mediated rejections were noted of which 5 were mixed antibody and cellular mediated rejections. Nine cellular mediated rejections were recorded. Two grafts were lost due to rejection in the first year. One-year graft survival of the ABOi grafts was comparable to 100 matched ABO compatible renal grafts, 96% versus 99%. At 5-year follow-up, the graft survival was 90% in the ABOi versus 97% in the control group. Posttransplantation immunoadsorption was not an essential part of the protocol and no association was found between antibody titers and subsequent graft rejection. Steroids could be withdrawn safely 3 months after transplantation. Adverse events specifically related to the ABOi protocol were not observed. The currently used ABOi protocol shows good short and midterm results despite a high rate of antibody mediated rejections in the first years after the start of the program.

    Blood group ABH(O) carbohydrate antigens are carried by precursor structures denoted type I-IV chains, creating unique antigen epitopes that may differ in expression between circulating erythrocytes and vascular endothelial cells. Characterization of such differences is invaluable in many clinical settings including transplantation. Monoclonal antibodies were generated and epitope specificities were characterized against chemically synthesized type I-IV ABH and related glycans. Antigen expression was detected on endomyocardial biopsies (n = 50) and spleen (n = 11) by immunohistochemical staining and on erythrocytes by flow cytometry. On vascular endothelial cells of heart and spleen, only type II-based ABH antigens were expressed; type III/IV structures were not detected. Type II-based ABH were expressed on erythrocytes of all blood groups. Group A1 and A2 erythrocytes additionally expressed type III/IV precursors, whereas group B and O erythrocytes did not. Intensity of A/B antigen expression differed among group A1 , A2 , A1 B, A2 B and B erythrocytes. On group A2 erythrocytes, type III H structures were largely un-glycosylated with the terminal "A" sugar α-GalNAc. Together, these studies define qualitative and quantitative differences in ABH antigen expression between erythrocytes and vascular tissues. These expression profiles have important implications that must be considered in clinical settings of ABO-incompatible transplantation when interpreting anti-ABO antibodies measured by hemagglutination assays with reagent erythrocytes. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    The paradigm of etiology of early childhood caries (ECC) is shifting toward genetics. Of various inherited factors, blood group of an individual is genetically determined. The aim of the study is to determine if blood group of an individual will serve as a potential risk factor in the development of ECC. A cross-sectional study was conducted in Chennai. Blood samples were collected from a total of 500 children age for determination of the blood group. Of which 96 children (24 per blood group) were randomly selected and were included in the study. Oral screening of the selected children was done by a pediatric dentist who was blinded to the blood group of the children. Decayed, extracted, and filling index was noted. Details on other associated factors for the development of ECC such as the socioeconomic status, oral hygiene measures, diet, and feeding practices were collected by directly interviewing the parents through a questionnaire. Statistical analysis was done using Chi-square and Kruskal-Wallis test and post hoc Tukey test with significance level set at 0.05. Intergroup analysis of the associated factors showed no significant differences between the children of different blood groups. A statistically significant relation was noted between the blood groups and development of ECC (P = 0.025). Blood group is a potential risk indicator for the development of ECC.

    We aimed to investigate the relationship between blood groups and pancreatic cancer in a Turkish population in Western Blacksea region. This is a retrospective study. Zonguldak Karaelmas University outpatient oncology clinic records were screened for the period between 2004 and 2011. The median age of patients were 56 (± 16) and 132 of 633 study population had pancreatic cancer. Pancreatic cancer patients had significantly higher rates of blood group A compared to controls (OR 1.8, 95%CI, p 0.005). Rates of blood group AB was significantly lower than the control group (OR 0.37, 95% CI, p 0.04). The median survival (IR) time in subjects having the blood groups A, B, AB and O were 7.0 (1-28), 7.0 (2-38), 10 (2-36) and 9.0 (2-48) months respectively; the blood group 0 had significantly higher overall survival (OS) compared to the non-0 groups (p 0.04). Pancreatic cancer patients had more common blood group A in our population. Moreover, blood group AB appeared to be a protective factor against pancreatic cancer in our population. Blood group 0 had a significantly longer survival compared to non-0, regardless of prognostic factors.

    Coagulative and fibrinolytic disorders appear to be associated with the development of lung cancer. The aim of the present study was to determine plasma levels of von Willebrand factor (VWF) and a disintegrin and metalloproteinase with a thrombospondin type 1 motif 13 (ADAMTS-13), and factor VIII (FVIII) activity, in association with O and non-O blood groups in patients with lung cancer. Plasma levels of VWF and ADAMTS-13, and FVIII activity were measured in 115 patients with lung cancer and 98 healthy subjects. Phenotyping of the ABO blood groups was also performed for the two groups. Significantly increased VWF levels and FVIII activity, as well as significantly decreased ADAMTS-13 levels, were observed in patients with distant metastasis as compared with those without distant metastasis and the healthy controls. Plasma VWF levels and FVIII activity were significantly increased in subjects with non-O type blood compared with those with type O blood in the two groups. However, a significant decrease in ADAMTS-13 levels was observed only in the control group among those with non-O type blood, compared with those with type O blood. The results of the present study indicate that increased VWF and decreased ADAMTS-13 levels facilitate the invasiveness and metastasis of lung cancer. Non-O blood groups constitute a risk factor for increased VWF and FVIII in plasma. Continued monitoring of VWF and ADAMTS-13 levels, and of FVIII activity in patients with lung cancer with distinct blood groups may help to minimize the incidence of thrombotic events and improve assessment of disease progression.

    Previous studies have identified ABO blood groups as predictors of thromboembolic diseases. In patients with atrial fibrillation (AF), however, potential association between ABO blood groups and the risk of left atrial (LA) and/or left atrial appendage (LAA) thrombogenic milieu (TM) has not been established. This is a retrospective case-control study that included 125 consecutive patients with non-valvular atrial fibrillation (NVAF) plus TM, as evidenced by transesophageal echocardiography (TEE) during a period from1 January 2010 to 31 December 2016. The controls were selected randomly from 1072 NVAF without TM at a 1:2 ratio. Potential association between ABO blood groups and TM was analyzed using multivariate logistic regression analysis. The risk of TM was higher in patients with blood group A (33.6% vs. 20.2% in non-A blood groups, P=0.005). After adjusting for age, sex, oral anticoagulant use, AF type and duration, and relevant functional measures (e.g., NT-pro BNP level, left atrium diameter, and left ventricular ejection fraction), blood group A remained associated with an increased risk of TM (OR=2.99, 95% CI 1.4-6.388, P=0.005). Blood group A is an independent risk factor for TM in NVAF patients. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available 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% followed by group B (n=77; 31.2%. Similarly, 239 (96.8% participants were Rh-positive as compared to 8 (3.2% Rh-negative. Interestingly, 46 (18.6% of the participants reported positive history of gastritis. Participants with blood group O had the greatest odds (OR=1.64 of having history of gastritis compared with those with other blood groups combined. Distribution of study participants based on gender and history of gastritis in either systems of blood grouping shoed no significant difference in their proportions (p>0.05. Conclusion: In light of the above findings, further longitudinal studies can be designed to better asses the relationship.

    Transplantation of the blood group A2B in a recipient was successfully performed in the setting of receiving a deceased donor kidney from an "incompatible" A1B donor. The donor and recipient were both typed for ABO blood group, including ABO genotyping. The donor and recipient were tested for ABO, non-ABO, and human leukocyte antigen (HLA) antibodies. The donor and recipient were typed for HLA antigens, including T- and B-flow cytometry crossmatch tests. The recipient's RBCs were negative with A1 lectin, and immunoglobulin G anti-A1 was demonstrated in the recipient's plasma. The donor-recipient pair was a four-antigen HLA mismatch, but final T- and B-flow cytometry crossmatch tests were compatible. The transplant procedure was uneventful; the patient experienced immediate graft function with no episodes of rejection or readmissions more than 2 years later. It may be safe to transplant across the A1/A2 blood group AB mismatch barrier in the setting of low titer anti-A1 isoagglutinins without the need for pretransplant desensitization even if the antibody produced reacts with anti-human globulin. © American Society for Clinical Pathology, 2016.

    Our study was aimed to investigate anesthetic effects of propofol in patients with different blood groups.A total of 72 participants were enrolled from patients arranged for surgeries of cholecystectomy, tonsillectomy, and spinal operation. Each blood group (A, B, AB, and O) contained 18 participants. Mean arterial pressure (MAP), heart rate (HR), and bispectral index (BIS) were assayed with Philips monitor. These indexes were observed before propofol anesthesia (T0), and then were recorded when concentration of propofol was 1 μg/mL (T1), 2 μg/mL (T2), 3 μg/mL (T3), and 4 μg/mL (T4). The differences in MAP, HR, and BIS at T0 among groups were compared with the χ test. Multiple comparisons were adopted to calculate the differences in MAP, HR, and BIS between groups at T1, T2, T3, and T4.No significant differences in age, sex, and weight of all groups were found (P > .05). Before propofol anesthesia (T0), all the participants exhibited no differences in MAP, HR, and BIS (P > .05). Subsequently, we found obvious differences in ΔMAP, ΔHR, and ΔBIS between groups. The patients in the B blood group showed highest ΔMAP and ΔHR at each time point (P blood group exhibited highest value at T3 and T4 (P blood group remarkably affects the anesthetic effects of propofol.

    ABO blood group is a hereditary factor of plasma levels of coagulation factor VIII (FVIII) and von Willebrand factor (VWF). Age and gender have been shown to influence FVIII, VWF, fibrinogen (Fbg), and ADAMTS13 (A disintegrin and metalloprotease with thrombospondin type 1 motif, 13). We investigated the effects of ABO type, age, and gender on plasma levels of FVIII, Fbg, VWF, and ADAMTS13 in a Chinese population. A total of 290 healthy volunteers were eligible for this study. ABO blood group was determined by indirect technique. FVIII:C and Fbg were measured by clotting assays. VWF antigen (VWF:Ag), collagen-binding activity (VWF:CBA), and ADAMTS13 antigen were assessed by ELISA, whereas VWF ristocetin cofactor activity (VWF:Rcof) was performed by agglutination of platelets with ristocetin. Mean FVIII:C and VWF levels (VWF:Ag, VWF:CBA, and VWF:Rcof) were significantly higher in non-O than in O type subjects ( p  blood group, age, and gender showed different effects on plasma levels of FVIII:C, Fbg, VWF:Ag, VWF:CBA, VWF:Rcof, and ADAMTS13 antigen. These new data on a Chinese population are quite helpful to compare with other ethnic groups.

    Full Text Available A doença de Jorge Lobo é uma micose de evolução crônica, causada pelo Lacazia loboi. Os mecanismos envolvidos na suscetibilidade/resistência do hospedeiro frente ao agente não estão ainda elucidados, dentre eles encontra-se a constituição genética. Portanto, o objetivo deste trabalho é avaliar a distribuição dos grupos sangüíneos ABO e Lewis de pacientes com doença de Jorge Lobo em relação à população geral. Foram analisados 13 pacientes provenientes do estado do Acre, 60 indivíduos da região de Bauru (SP não acometidos pela doença em estudo (grupo controle Lewis e 2.673 doadores do Banco de Sangue da cidade de Rio Branco (AC como grupo controle ABO. As presenças dos antígenos eritrocitários foram determinadas pela reação de aglutinação em tubo através dos soros anti-AB, anti-A e anti-B para o fenótipo ABO e dos soros anti-Lewis a e Lewis b para fenotipagem Lewis. As freqüências fenotípicas Lewis e ABO nos pacientes e nos controles são, respectivamente: Le (a- b+ = 54,0% X 72,0%, Le (a+ b- = 15,0% X 6,0%, Le (a- b- = 31,0% X 22,0% ; A =15,4% X 33,6%, B = 30,8% X 10,8%, O = 53,8% X 52,9%, AB = 0 X 2,7%.

    ABO-incompatible (ABOi) organ transplantation is performed owing to unremitting donor shortages. Defining mechanisms of antibody-mediated rejection, accommodation, and tolerance of ABOi grafts is limited by lack of a suitable animal model. We report generation and characterization of a murine model to enable study of immunobiology in the setting of ABOi transplantation. Transgenesis of a construct containing human A1- and H-transferases under control of the ICAM-2 promoter was performed in C57BL/6 (B6) mice. A-transgenic (A-Tg) mice were assessed for A-antigen expression by histology and flow cytometry. B6 wild-type (WT) mice were sensitized with blood group A-human erythrocytes; others received passive anti-A monoclonal antibody and complement after heart transplant. Serum anti-A antibodies were assessed by hemagglutination. "A-into-O" transplantation (major histocompatibility complex syngeneic) was modeled by transplanting hearts from A-Tg mice into sensitized or nonsensitized WT mice. Antibody-mediated rejection was assessed by morphology/immunohistochemistry. A-Tg mice expressed A-antigen on vascular endothelium and other cells including erythrocytes. Antibody-mediated rejection was evident in 15/17 A-Tg grafts in sensitized WT recipients (median titer, 1:512), with 2 showing hyperacute rejection and rapid cessation of graft pulsation. Hyperacute rejection was observed in 8/8 A-Tg grafts after passive transfer of anti-A antibody and complement into nonsensitized recipients. Antibody-mediated rejection was not observed in A-Tg grafts transplanted into nonsensitized mice. A-Tg heart grafts transplanted into WT mice with abundant anti-A antibody manifests characteristic features of antibody-mediated rejection. These findings demonstrate an effective murine model to facilitate study of immunologic features of ABOi transplantation and to improve potential diagnostic and therapeutic strategies.

    Osteoporosis is known as a degenerative disease of the skeletal system and its main complication is fracture, which influences quality of life in the elderly. There are 4 major blood groups in humans based on the presence of A and B antigens. According to the investigations, there are reported relations between blood types and some diseases. In this study, the association between the ABO blood group and the prevalence of osteoporosis and osteopenia in an elderly population was investigated. Medical records of 990 elderly people were investigated in a cross-sectional study and the association between their blood group and the incidence of osteoporosis and osteopenia was analyzed using SPSS version 17.0 (SPSS Inc., Chicago, IL, USA). The results showed that ABO blood groups had no association with the prevalence of osteoporosis in both elderly men and women. The association between age and osteoporosis was significant and the association between this disorder and gender was significant too. The results also indicate that there is no association between RH + and RH - blood types and osteoporosis and osteopenia in both men and women. Based on this finding, it would be reasonable to conduct extensive studies. Copyright © 2016. Published by Elsevier Inc.

    The identification of epidemiological factors increasing the risk of endometriosis could shorten the time to diagnosis. Specific blood groups may be more common in patients with endometriosis. We designed a cross-sectional study of 633 Caucasian women living in the same geographic area. Study group included 311 patients with histologically proven endometriosis. Control group included 322 patients without endometriosis as checked during surgery. Frequencies of ABO and Rhesus groups in the study and control groups were compared using univariate and multivariate analyses. We observed a higher proportion of Rh-negative women in the study group, as compared to healthy controls. Multivariate analysis showed that Rh-negative women are twice as likely to develop endometriosis (aOR = 1.90; 95% CI: 1.20-2.90). There was no significant difference in ABO group distribution between patients and controls. There was no difference when taking into account either the clinical forms (superficial endometriosis, endometrioma, and deep infiltration endometriosis) or the rAFS stages. Rh-negative women are twice as likely to develop endometriosis. Chromosome 1p, which contains the genes coding for the Rhesus, could also harbor endometriosis susceptibility genes.

    In the Model for End-Stage Liver Disease (MELD) system, patients with "MELD exceptions" points may have unfair privilege in the competition for liver grafts. Furthermore, organ distribution following identical ABO blood types may also result in unjust organ allocation. The aim of this study was to investigate access to liver transplantation in a tertiary Brazilian center, regarding "MELD exceptions" situations and among ABO-blood groups. A total of 465 adult patients on the liver waitlist from August 2015 to August 2016 were followed up until August 2017. Patients were divided into groups according to ABO-blood type and presence of "exceptions points." No differences in outcomes were observed among ABO-blood groups. However, patients from B and AB blood types spent less time on the list than patients from A and O groups (median, 46, 176, 415, and 401 days, respectively; P = .03). "Exceptions points" were granted for 141 patients (30.1%), hepatocellular carcinoma being the most common reason (52.4%). Patients with "exceptions points" showed higher transplantation rate, lower mortality on the list, and lower delta-MELD than non-exceptions patients (56.7% vs 19.1% [P blood types, despite shorter time on the waitlist for AB and B groups. The current MELD exception system provides advantages for candidates with "exception points," resulting in superior outcomes compared with those without exceptions. Copyright © 2018 Elsevier Inc.

    Full Text Available While circulating levels of soluble Intercellular Adhesion Molecule 1 (sICAM-1 have been associated with diverse conditions including myocardial infarction, stroke, malaria, and diabetes, comprehensive analysis of the common genetic determinants of sICAM-1 is not available. In a genome-wide association study conducted among 6,578 participants in the Women's Genome Health Study, we find that three SNPs at the ICAM1 (19p13.2 locus (rs1799969, rs5498 and rs281437 are non-redundantly associated with plasma sICAM-1 concentrations at a genome-wide significance level (P<5x10(-8, thus extending prior results from linkage and candidate gene studies. We also find that a single SNP (rs507666, P = 5.1x10(-29 at the ABO (9q34.2 locus is highly correlated with sICAM-1 concentrations. The novel association at the ABO locus provides evidence for a previously unknown regulatory role of histo-blood group antigens in inflammatory adhesion processes.

    ABO and Rh blood groups play a vital role in blood transfusion safety and clinical practice and are thought to be linked with disease susceptibility. The results from previous studies that focused on the association between blood groups and HBV infection remain controversial. China has the world's largest burden of HBV infection. We assessed the distribution of ABO/Rh blood groups in Chinese adults and examined the association between these groups and HBV infection. We did a nationwide cross-sectional study using data from a physical check-up programme from 31 provinces examined between 2010 and 2012. ELISA was used to test for HBsAg in serologic samples. Multivariable logistic regression was used to estimate aOR of the association between ABO and Rh blood groups and HBV infection. Among 3 827 125 participants, the proportion of participants with blood group A was highest (30.54%), followed by O (30.37%), B (29.42%) and AB (9.66%). A total of 38 907 (1.02%) were Rh-D negative. The prevalence of HBsAg in blood groups O, A, B and AB were 6.34%, 5.55%, 5.18% and 5.06%, respectively. HBsAg prevalence was 5.65% in Rh-D-positive and 3.96% in Rh-D-negative participants. After controlling for other potential risk factors, multivariate models showed that participants with blood group O (adjusted OR = 1.22, 95% CI: 1.20-1.25) were at higher risk of HBV infection compared with group AB. Rh-D-positive participants (adjusted OR = 1.44, 95% CI: 1.37-1.52) were at higher risk of HBV infection than Rh-D-negative participants. The associations between ABO/Rh blood groups and HBV infection were similar in subgroup analysis. The proportions of O, A, B and AB blood groups were approximately 3:3:3:1, and nearly 1 in 100 people was Rh-D negative among Chinese adults. Blood group O and Rh-D positivity were both associated with increased HBV infection. The risk of HBV infection and blood safety should be taken into consideration in clinical practice, especially when transfusing

    Full Text Available Mucins are heavily O-glycosylated proteins where the glycosylation has been shown to play an important role in cancer. Normal epithelial ovarian cells do not express secreted mucins, but their abnormal expression has previously been described in epithelial ovarian cancer and may relate to tumor formation and progression. The cyst fluids were shown to be a rich source for acidic glycoproteins. The study of these proteins can potentially lead to the identification of more effective biomarkers for ovarian cancer.In this study, we analyzed the expression of the MUC5AC and the O-glycosylation of acidic glycoproteins secreted into ovarian cyst fluids. The samples were obtained from patients with serous and mucinous ovarian tumors of different stages (benign, borderline, malignant and grades. The O-linked oligosaccharides were released and analyzed by negative-ion graphitized carbon Liquid Chromatography (LC coupled to Electrospray Ionization tandem Mass Spectrometry (ESI-MSn. The LC-ESI-MSn of the oligosaccharides from ovarian cyst fluids displayed differences in expression of fucose containing structures such as blood group ABO antigens and Lewis-type epitopes.The obtained data showed that serous and mucinous benign adenomas, mucinous low malignant potential carcinomas (LMPs, borderline and mucinous low-grade carcinomas have a high level of blood groups and Lewis type epitopes. In contrast, this type of fucosylated structures were low abundant in the high-grade mucinous carcinomas or in serous carcinomas. In addition, the ovarian tumors that showed a high level of expression of blood group antigens also revealed a strong reactivity towards the MUC5AC antibody. To visualize the differences between serous and mucinous ovarian tumors based on the O-glycosylation, a hierarchical cluster analysis was performed using mass spectrometry average compositions (MSAC.Mucinous benign and LMPs along with mucinous low-grade carcinomas appear to be different from

    Aim of the study: The aim of the study was to find out the frequency of Hepatitis B Hepatitis C, Syphilis, HIV and malaria in apparently healthy blood donors and to find out any association between ABO and Rh blood groups. Methods: It was a descriptive study carried out at Rehman Medical Institute laboratory. All blood donors who volunteered for blood donation from Jan 2008 to Dec 2014 were reviewed for blood groups and screening tests. Those who were eligible were then screened for Hepatitis B, Hepatitis C, HIV, syphilis and malaria on Architect 8200i through chemiluminescent immunoassay whereas malaria was screened by a thin film. Blood group was determined by both forward and reverse grouping. Statistical analysis was carried out using SPSS software and expressed as frequencies. Results: A total of 41033 apparently healthy donors were included in the study. All of them were voluntary donors. Their age ranged from 18-70 years with a mean age of 38+-10.5 years. Out of these 41033, 40245 (98.3%) were males and 788(1.9%) were females. The most frequent blood group was B positive followed by O positive. Out of 41033 donors 961 (2.30%) had Hepatitis B, 566 (1.30%) had Hepatitis C, 363 (0.90%) had syphilis, 311 (0.76%) had malaria and 30 (0.07%) had HIV. There is a significant association between A blood group and HIV and hepatitis B. Donors with blood group O had no significant association with any blood transmitted infection. Conclusion: Blood group O may have some influence in protecting against blood transmitted infection. People having Blood group A are more prone to get Hepatitis B and HIV. (author)

    Blood transfusion through the intraosseous route is gaining popularity in emergency medicine. Pretransfusion peripheral blood (PB) samples are usually not available in these patients, leading to discrepancies in blood group typing and a possible delay in transferring to group-specific blood products. The aim of this study was to assess the feasibility of ABO and D typing and red blood cell alloantibody screening in marrow (BM) samples. Direct and reverse ABO typing, D typing, and a two-cell alloantibody screen were performed in EDTA-anticoagulated BM samples with standard manual column agglutination techniques. EDTA-anticoagulated PB samples were used as controls. The mean age of the study subjects (n = 71) was 47 years (range, 1-82 years). All ABO groups and both D+ and D- types were represented. In all subjects, concordant results were observed for all analyses in BM and PB samples. In 15 (21%) of the samples, a discrepancy of one reaction strength step (1+) was observed in at least one of the analyses (Cohen's weighted κ = 0.993); this did not affect interpretation of the results. Blood group typing and alloantibody screening are feasible in BM samples, providing proof-of-concept that intraosseous samples for blood group serologic analyses can be collected from emergency patients before intraosseous blood transfusion. This will enable a timely transfer to group-specific blood products and enable conservation of the valuable universal-donor blood products. © 2018 AABB.

    The aim of our study was to determine the incidence and causes of ABO typing discrepancies among patients and blood donors at our centre. An accurate interpretation of the ABO blood group of an individual is of utmost importance to ensure patient safety and good transfusion practices. A retrospective observational study was carried out in the Department of Transfusion Medicine in our hospital from March 2013 to December 2015. Records of all patient and blood donor samples were retrieved and analysed for ABO typing discrepancies. In total, 135 853 patient and 62 080 donor samples were analysed for ABO typing discrepancies. The incidence among patients and blood donors was found to be 0·1% (138/135853) and 0·02% (14/62080), respectively. The mean age for patients and blood donors was 48·4 and 29·2 years, respectively. The most common cause of ABO typing discrepancies was due to cold autoantibodies among the patients (50·7%) and blood donors (57%) causing discrepant results in reverse typing. The various other causes of reverse typing discrepancies among patients were weak/missing antibody (25·4%), cold-reacting alloantibody (4·3%), warm autoantibody (2·2%), anti-A1 antibody (2·2%), Bombay phenotype (1·5%), transplantation (0·7%) and rouleaux (0·7%), whereas in blood donors, the causes were cold-reacting antibody (7%) and weak antibody (7%). The major cause of forward typing discrepancies among patients (12·3%) and blood donors (29%) was ABO subgroups. The resolution of ABO typing discrepancy is essential to minimise the chance of transfusion of ABO-incompatible blood. © 2018 British Blood Transfusion Society.

    To determine whether corneal graft survival over a 5-year follow-up period was affected by ABO blood type compatibility in participants in the Cornea Donor Study undergoing corneal transplantation principally for Fuchs dystrophy or pseudophakic corneal edema, conditions at low-risk for graft rejection. Multi-center prospective, double-masked, clinical trial. ABO blood group compatibility was determined for 1,002 donors and recipients. During a 5-year follow-up period, episodes of graft rejection were documented, and graft failures were classified as to whether or not they were attributable to immunologic rejection. Endothelial cell density was determined by a central reading center for a subset of subjects. ABO donor-recipient incompatibility was not associated with graft failure attributable to any cause including graft failure because of rejection, or with the occurrence of a rejection episode. The 5-year cumulative incidence of graft failure attributable to rejection was 32 (6%) for recipients with ABO recipient-donor compatibility and 12 (4%) for those with ABO incompatibility (hazard ratio, 0.65; 95% confidence interval, 0.33 to 1.25; P = .20). The 5-year incidence for a definite rejection episode, irrespective of whether graft failure ultimately occurred, was 64 (12%) for ABO compatible compared with 25 (8%) for ABO incompatible cases (P = .09). Among clear grafts at 5 years, percent loss of endothelial cells was similar in ABO compatible and incompatible cases. In patients undergoing penetrating keratoplasty for Fuchs dystrophy or pseudophakic corneal edema, ABO matching is not indicated since ABO incompatibility does not increase the risk of transplant failure attributable to graft rejection.

    Objective Blood type A and the A1 allele have been associated with increased ovarian cancer risk. With only two small studies published to date, evidence for an association between ABO blood type and ovarian cancer survival is limited. Methods We conducted a retrospective cohort study of Tumor Registry confirmed ovarian cancer cases from the Vanderbilt University Medical Center with blood type from linked laboratory reports and ABO variants from linked Illumina Exome BeadChip data. Associations with overall survival (OS) were quantified by hazard ratios (HR) and confidence intervals (CI) from proportional hazards regression models; covariates included age, race, stage, grade, histologic subtype, and year of diagnosis. Results ABO phenotype (N = 694) and/or genotype (N = 154) data were available for 713 predominantly Caucasian (89.3%) cases. In multivariable models, blood type A had significantly better OS compared to either O (HR: 0.75, 95% CI: 0.60–0.93) or all non-A (HR: 0.77, 95% CI: 0.63–0.94) cases. Similarly, missense rs1053878 minor allele carriers (A2) had better OS (HR: 0.50, 95% CI: 0.25–0.99). Among Caucasians, this phenotype association was strengthened, but the genotype association was attenuated; instead, four variants sharing moderate linkage disequilibrium with the O variant were associated with better OS (HR: 0.62, 95% CI: 0.39–0.99) in unadjusted models. Conclusions Blood type A was significantly associated with longer ovarian cancer survival in the largest such study to date. This finding was supported by genetic analysis, which implicated the A2 allele, although O related variants also had suggestive associations. Further research on ABO and ovarian cancer survival is warranted. PMID:28448592

    We developed a sequence-specific primer PCR (SSP-PCR) for detection of a 5.8-kb deletion (B(m) 5.8) involving an erythroid cell-specific regulatory element in intron 1 of the ABO blood group gene. Using this SSP-PCR, we performed genetic analysis of 382 individuals with Bm or ABm. The 5.8-kb deletion was found in 380 individuals, and disruption of the GATA motif in the regulatory element was found in one individual. Furthermore, a novel 3.0-kb deletion involving the element (B(m) 3.0) was demonstrated in the remaining individual. Comparisons of single-nucleotide polymorphisms and microsatellites in intron 1 between B(m) 5.8 and B(m) 3.0 suggested that these deletions occurred independently. © 2014 International Society of Blood Transfusion.

    BACKGROUND Postoperative cognitive dysfunction (POCD) is a postoperative complication after surgery and anesthesia. Whether ABO blood types are associated with POCD in elderly patients undergoing unilateral total hip arthroplasty surgery in China is unclear. MATERIAL AND METHODS Firstly, 142 elderly patients were divided into a POCD group and a non-POCD group according to the Mini Mental State Examination (MMSE) scores and ABO blood types were analyzed. Secondly, according to ABO blood type, the selected 226 patients were divided into 4 groups: type A group, type B group, type AB group, and type O group. Then, all patients completed the MMSE before and after surgery. Finally, the occurrence of POCD was recorded and related data were analyzed. RESULTS Firstly, there was a significant difference in both groups in terms of distribution of ABO blood types, and elderly patients who developed POCD were more likely to have type A blood and less likely to have type O blood. Secondly, compared with elderly patients with type A blood, those with type O had higher MMSE scores on the first day and the seventh day after surgery. Finally, the risk of developing POCD was significantly higher in patients with type A blood and on the first day and the seventh day after surgery the risk of developing POCD was significantly lower in patients with type O blood. CONCLUSIONS Elderly patients with type A blood have higher risk of developing early POCD and those with type O blood have less risk of developing early POCD.

    Platelets play a central role in the inflammation response via CD40 ligand (CD40L) expression, which may lead to transfusion reactions. The precise role of platelet CD40L-mediated inflammation in transfusion reactions is unclear. Therefore, we assessed the effects of in vitro blood mixing on platelet CD40L expression. In addition, we examined the effect of ABO compatibility on CD40L expression. Donor packed red blood cells were acquired from a blood bank, and recipient blood was obtained from patients undergoing cardiac surgery and prepared as washed platelets. Donor blood was mixed with suspended, washed recipient platelets to obtain a final mixing ratio of 1%, 5%, or 10% (vol/vol). The blood mixtures were divided into three groups: Group M, cross-matched blood-type mixing (n = 20); Group S, ABO type-specific uncross-matched blood (n = 20); and Group I, ABO incompatibility (not ABO type-specific blood and not process cross-matched) mixing (n = 20). The blood mixtures were used to detect platelet membrane-bound CD40L expression by flow cytometry. Blood mixing resulted in an increase in CD40L expression in Group M (P role in the induction of CD40L expression.

    Background Reference intervals for venous blood parameters differs with age, gender, geographic region, and ethnic groups. Hence local laboratory reference intervals are important to improve the diagnostic accuracy of health assessments and diseases. However, there have been no comprehensive published reference intervals established in Oman, the Gulf Cooperation Council or Middle Eastern countries. Hence, the aim of this study was to establish reference intervals for full blood count in healthy Omani adults. Methods Venous blood specimens were collected from 2202 healthy individuals aged 18 to 69 years from January 2012 to April 2017, and analysed by Sysmex XS-1000i and Cell-Dyn Sapphire automated haematology analysers. Results were statistically analysed and compared by gender, age, and ABO blood group. The lower and upper reference limits of the haematology reference intervals were established at the 2.5th and 97.5th percentiles respectively. Results Reference intervals were calculated for 17 haematology parameters which included red blood cell, white blood cell, and platelet parameters. Red blood cell (RBC), haemoglobin (HGB), haematocrit (HCT), platelet and platelet haematocrit counts of the healthy donors were significantly different between males and females at all ages (p values of RBC, HGB and HCT than females. Other complete blood count parameters showed no significant differences between genders, age groups, instruments, or blood groups. Our study showed a lower haemoglobin limit for the normal reference interval in males and females than the currently used in Oman. Conclusions Data from this study established specific reference intervals which could be considered for general use in Oman. The differences in haematology reference intervals highlights the necessity to establish reference intervals for venous blood parameters among the healthy population in each country or at least in each region.

    In patients with non-aneurysmal subarachnoid hemorrhage (NA-SAH), the etiology is unknown and the bleeding source remains unidentified. However, the ABO blood type system has a profound role in patient's hemostasis and thrombosis. To date, the aspect of ABO blood type in incidence, clinical course, and outcome after NA-SAH has not been investigated. In this retrospective analysis, 81 patients with non-traumatic and non-aneurysmal subarachnoid hemorrhage treated between 2010 and 2014 at the author's institution were included. WFNS admission status, cerebral vasospasm, delayed infarction, ventriculoperitoneal shunt necessity, the Fisher grade, and the modified Rankin Scale were analyzed for their association with ABO blood type. Four hundred seventy patients with aneurysmal subarachnoid hemorrhage served as a control group. The AB blood type is more frequent in NA-SAH compared to aneurysmal patients and the German population (OR 2.45, p ≤ 0.05). Furthermore, NA-SAH with AB blood type showed a similar sequelae compared to aneurysmal patients in terms of shunt necessity (OR 2.00, p ≥ 0.05), cerebral vasospasm (OR 1.66, p ≥ 0.05), and delayed infarctions (OR 1.07, p ≥ 0.05). The clinical course of NA-SAH AB blood type patients shows similar severity as of aneurysmal subarachnoid hemorrhage. Therefore, patients with AB blood type should be under intensified observation.

    The evolution of human blood groups, without doubt, has a history as old as man himself. There are at least three hypotheses about the emergence and mutation of human blood groups. Global distribution pattern of blood groups depends on various environmental factors, such as disease, climate, altitude, humidity etc. In this survey, the collection of main blood groups ABO and Rh, along with some minor groups, are presented. Several investigations of blood groups from Iran, particularly a large sampling on 291857 individuals from Iran, including the main blood groups ABO and Rh, as well as minor blood groups such as Duffy, Lutheran, Kell, KP, Kidd, and Xg, have been reviewed.

  17. Surface plasmon resonance analysis shows an IgG-isotype-specific defect in ABO blood group antibody formation in patients with common variable immunodeficiency

    Directory of Open Access Journals (Sweden)

    Michael Bernhard Fischer

    2015-05-01

    Full Text Available Background: Common variable immunodeficiency (CVID is the most common clinically severe primary immunodeficiency and comprises a heterogeneous group of patients with recurrent severe bacterial infections due to the failure to produce IgG antibodies after exposure to infectious agents and immunization. Diagnostic recommendations for antibody failure include assessment of isoagglutinins. We have readdressed this four decades old but still accepted recommendation with up to date methodology.Methods: Anti-A/B IgM- and IgG-antibodies were measured by Diamed-ID Micro Typing, surface plasmon resonance (SPR using the Biacore® device and flow cytometry.Results: When Diamed-ID Micro Typing was used, CVID patients (n=34 showed IgG- and IgM-isoagglutinins that were comparable to healthy volunteers (n=28, while all XLA patients (n=8 had none. Anti-A/B IgM-antibodies were present in more than 2/3 of the CVID patients and showed binding kinetics comparable to anti-A/B IgM-antibodies from healthy individuals. A correlation could be found in CVID patients between levels of anti-A/B IgM-antibodies and levels of serum IgM and PnP-IgM-antibodies. In contrast in CVID patients as a group ABO antibodies were significantly decreased when assessed by SPR, which correlated with levels of switched memory, non-switched memory and naïve B cells, but all CVID patients had low/undetectable anti-A/B IgG-antibodies.Conclusion: These results indicate that conventional isoagglutinin assessment and assessment of anti-A/B IgM antibodies are not suited for the diagnosis of impaired antibody production in CVID. Examination of anti-A/B IgG antibodies by SPR provides a useful method for the diagnosis of IgG antibody failure in all CVID patients studied, thus indicating an important additional rationale to start immunoglobulin replacement therapy early in these patients, before post-infectious sequelae develop.

    Human error has been identified as a major source of ABO-incompatible blood transfusion which most often results from blood being given to the wrong patient. We present a case of inadvertent administration of ABO-incompatible blood to a 6-mo-old child who underwent congenital heart surgery and discuss the use of invasive therapeutic approaches. Invasive techniques included total circulatory arrest and large-volume exchange transfusion, along with conventional ultrafiltration and plasmapheresis, which could all be performed rapidly and effectively. The combination of standard pharmacologic therapies and alternative invasive techniques after a massive ABO-incompatible blood transfusion led to a favorable outcome in our patient.

    2014-01-01

    Full Text Available Background and Objectives: The study was undertaken with the objective to provide data on the ABO and Rh(D blood group distribution and gene frequency across India. Materials and Methods: A total of 10,000 healthy blood donors donating in blood banks situated in five different geographical regions of the country (North, South, East and Center were included in the study. ABO and Rh (D grouping was performed on all these samples. Data on the frequency of ABO and Rh(D blood groups was reported in simple numbers and percentages. Results: The study showed that O was the most common blood group (37.12% in the country closely followed by B at 32.26%, followed by A at 22.88% while AB was the least prevalent group at 7.74%. 94.61% of the donor population was Rh positive and the rest were Rh negative. Regional variations were observed in the distribution. Using the maximum likelihood method, the frequencies of the I A , I B and I O alleles were calculated and tested according to the Hardy Weinberg law of Equilibrium. The calculated gene frequencies are 0.1653 for I A (p, 0.2254 for I B (q and 0.6093 for I O (r. In Indian Population, O (r records the highest value followed by B (q and A (p; O > B > A. Conclusion: The study provides information about the relative distribution of various alleles in the Indian population both on a pan-India basis as well as region-wise. This vital information may be helpful in planning for future health challenges, particularly planning with regards to blood transfusion services.

    Erycard 2.0 is a "point-of-care" device that is primarily being used for patient blood grouping before transfusion. Erycard 2.0 was compared with conventional slide technology for accuracy and time taken for ABO and Rh forward grouping result with column agglutination technology (CAT) being the gold standard. Erycard 2.0 as a device was also evaluated for its stability under different storage conditions and stability of result till 48 h. In addition, grouping of hemolyzed samples was also tested with Erycard 2.0. Ease of use of Erycard 2.0 was evaluated with a survey among paramedical staff. Erycard 2.0 demonstrated 100% concordance with CAT as compared with slide technique (98.9%). Mean time taken per test by Erycard 2.0 and slide technique was 5.13 min and 1.7 min, respectively. After pretesting storage under different temperature and humidity conditions, Erycard 2.0 did not show any deviation from the result. The result did not change even after 48 h of testing and storage under room temperature. 100% concordance was recorded between pre- and post-hemolyzed blood grouping. Ease of use survey revealed that Erycard 2.0 was more acceptable to paramedical staff for its simplicity, objectivity, and performance than conventional slide technique. Erycard 2.0 can be used as "point-of-care" device for blood donor screening for ABO and Rh blood group and can possibly replace conventional slide technique.

    The ABO blood type is one of the most common and widely used genetic traits in humans. Three glycosyltransferase-encoding gene alleles, I A , I B and i, produce three red blood cell surface antigens, by which the ABO blood type is classified. By using the ABO blood type experiment as an ideal case for genetics teaching, we can easily introduce to the students several genetic concepts, including multiple alleles, gene interaction, single nucleotide polymorphism (SNP) and gene evolution. Herein we have innovated and integrated our ABO blood type genetics experiments. First, in the section of Molecular Genetics, a new method of ABO blood genotyping was established: specific primers based on SNP sites were designed to distinguish three alleles through quantitative real-time PCR. Next, the experimental teaching method of Gene Evolution was innovated in the Population Genetics section: a gene-evolution software was developed to simulate the evolutionary tendency of the ABO genotype encoding alleles under diverse conditions. Our reform aims to extend the contents of genetics experiments, to provide additional teaching approaches, and to improve the learning efficiency of our students eventually.

  5. Replication and Characterization of Association between ABO SNPs and Red Blood Cell Traits by Meta-Analysis in Europeans.

    Directory of Open Access Journals (Sweden)

    Stela McLachlan

    Full Text Available Red blood cell (RBC traits are routinely measured in clinical practice as important markers of health. Deviations from the physiological ranges are usually a sign of disease, although variation between healthy individuals also occurs, at least partly due to genetic factors. Recent large scale genetic studies identified loci associated with one or more of these traits; further characterization of known loci and identification of new loci is necessary to better understand their role in health and disease and to identify potential molecular mechanisms. We performed meta-analysis of Metabochip association results for six RBC traits-hemoglobin concentration (Hb, hematocrit (Hct, mean corpuscular hemoglobin (MCH, mean corpuscular hemoglobin concentration (MCHC, mean corpuscular volume (MCV and red blood cell count (RCC-in 11 093 Europeans from seven studies of the UCL-LSHTM-Edinburgh-Bristol (UCLEB Consortium. We identified 394 non-overlapping SNPs in five loci at genome-wide significance: 6p22.1-6p21.33 (with HFE among others, 6q23.2 (with HBS1L among others, 6q23.3 (contains no genes, 9q34.3 (only ABO gene and 22q13.1 (with TMPRSS6 among others, replicating previous findings of association with RBC traits at these loci and extending them by imputation to 1000 Genomes. We further characterized associations between ABO SNPs and three traits: hemoglobin, hematocrit and red blood cell count, replicating them in an independent cohort. Conditional analyses indicated the independent association of each of these traits with ABO SNPs and a role for blood group O in mediating the association. The 15 most significant RBC-associated ABO SNPs were also associated with five cardiometabolic traits, with discordance in the direction of effect between groups of traits, suggesting that ABO may act through more than one mechanism to influence cardiometabolic risk.

    Essentials von Willebrand factor (VWF) and factor VIII (FVIII) levels are modulated by age and ABO status. The effect of aging and ABO blood type on VWF and FVIII was assessed in 207 normal individuals. Aging and ABO blood type showed combined and bidirectional influences on VWF and FVIII levels. Aging and ABO blood type influence VWF levels through both secretion and clearance mechanisms. Background The effect of aging and ABO blood type on plasma levels of von Willebrand factor (VWF) and factor VIII (FVIII) have been widely reported; however, a comprehensive analysis of their combined effect has not been performed and the mechanisms responsible for the age-related changes have not been determined. Objectives To assess the influence of aging and ABO blood type on VWF and FVIII levels, and to evaluate the contribution of VWF secretion and clearance to the age-related changes. Methods A cross-sectional observational study was performed in a cohort of 207 normal individuals, whose levels of VWF, FVIII, VWF propeptide (VWFpp), VWFpp/VWF:Ag ratio and blood type A antigen content on VWF (A-VWF) were quantified. Results Aging and ABO blood type exerted interrelated effects on VWF and FVIII plasma levels, because the age-related increase in both proteins was significantly higher in type non-O individuals (β = 0.011 vs. 0.005). This increase with age in non-O subjects drove the differences between blood types in VWF levels, as the mean difference increased from 0.13 U/mL in the young to 0.57 U/mL in the old. Moreover, A-VWF was associated with both VWF antigen (β = 0.29; 95% confidence interval [CI], 0.09, 0.50) and VWF clearance (β = -0.15; 95% CI, -0.25, -0.06). We also documented an effect of ABO blood type on VWF secretion with aging, as old individuals with blood type non-O showed higher levels of VWFpp (mean difference 0.29 U/mL). Conclusions Aging and ABO blood type have an interrelated effect on VWF and FVIII levels, where the effect of one is significantly

    Immunotherapies for cancer are transforming patient care, but clinical responses vary considerably from patient to patient. Simple, inexpensive strategies to target treatment to likely responders could substantially improve efficacy while simultaneously reducing health care costs, but identification of reliable biomarkers has proven challenging. Previously, we found that pre-treatment serum IgM to blood group A (BG-A) correlated with survival for patients treated with PROSTVAC-VF, a therapeutic cancer vaccine in phase III clinical trials for the treatment of prostate cancer. These results suggested that ABO blood type might influence efficacy. Unfortunately, blood types were not available in the clinical records for all but 8 patients and insufficient amounts of sera were left for standard blood typing methods. To test the hypothesis, therefore, we developed a new glycan microarray-based method for determining ABO blood type. The method requires only 4 μL of serum, provides 97% accuracy, and allows simultaneous profiling of many other serum anti-glycan antibodies. After validation with 220 healthy subjects of known blood type, the method was then applied to 74 PROSTVAC-VF patients and 37 control patients from a phase II trial. In this retrospective study, we found that type B and O PROSTVAC-VF patients demonstrated markedly improved clinical outcomes relative to A and AB patients, including longer median survival, longer median survival relative to Halabi predicted survival, and improved overall survival via Kaplan-Meier survival analysis (p = 0.006). Consequently, blood type may provide an inexpensive screen to pre-select patients likely to benefit from PROSTVAC-VF therapy.

    Many hospitals opt for early postnatal discharge of newborns with a potential risk of readmission for neonatal hyperbilirubinemia. Assays/algorithms with the possibility to improve prediction of significant neonatal hyperbilirubinemia are needed to optimize screening protocols and safe discharge of neonates. This study investigated the predictive value of umbilical cord blood (UCB) testing for significant hyperbilirubinemia. Neonatal UCB bilirubin, UCB direct antiglobulin test (DAT), and blood group were determined, as well as the maternal blood group and the red blood cell antibody status. Moreover, in newborns with clinically apparent jaundice after visual assessment, plasma total bilirubin (TB) was measured. Clinical factors positively associated with UCB bilirubin were ABO incompatibility, positive DAT, presence of maternal red cell antibodies, alarming visual assessment and significant hyperbilirubinemia in the first 6 days of life. UCB bilirubin performed clinically well with an area under the receiver-operating characteristic curve (AUC) of 0.82 (95 % CI 0.80-0.84). The combined UCB bilirubin, DAT, and blood group analysis outperformed results of these parameters considered separately to detect significant hyperbilirubinemia and correlated exponentially with hyperbilirubinemia post-test probability. Post-test probabilities for neonatal hyperbilirubinemia can be calculated using exponential functions defined by UCB bilirubin, DAT, and ABO compatibility results. • The diagnostic value of the triad umbilical cord blood bilirubin measurement, direct antiglobulin testing and blood group analysis for neonatal hyperbilirubinemia remains unclear in literature. • Currently no guideline recommends screening for hyperbilirubinemia using umbilical cord blood. What is New: • Post-test probability for hyperbilirubinemia correlated exponentially with umbilical cord blood bilirubin in different risk groups defined by direct antiglobulin test and ABO blood group

    The molecular characterization of ABO blood types, which is clinically significant in blood transfusion, has clinical and anthropological importance. Polymerase chain reaction sequence-based typing (PCR-SBT) is one of the most commonly used methods for the analysis of genetic bases of ABO blood types. However, such methods as PCR-SBT are time-consuming and are high in demand of equipments and manipulative skill. Here we showed that membrane electrophoresis based SERS method employed for studying the molecular bases of ABO blood types can provide rapidand easy-operation with high sensitivity and specificity. The plasma proteins were firstly purified by membrane electrophoresis and then mixed with silver nanoparticles to perform SERS detection. We use this method to classify different blood types, including blood type A (n=13), blood type B (n=9) and blood type O (n=10). Combination of principal component analysis (PCA) and liner discriminant analysis (LDA) was then performed on the SERS spectra of purified albumin, showing good classification results among different blood types. Our experimental outcomes represent a critical step towards the rapid, convenient and accurate identification of ABO blood types.

    Full Text Available ABO blood type is an inherited characteristic. The associations between ABO blood type and risk of all cancer and specific cancers were examined in a prospective cohort study of 18,244 Chinese men enrolled in 1986. During the 25 years of follow-up, 3,973 men developed cancer including 964 lung cancers, 624 colorectal cancers, 560 gastric cancers, 353 liver cancers, and 172 urinary bladder cancers. Hazard ratios (HR for all cancer and specific cancers by ABO blood type were calculated using Cox proportional hazards models. Compared with blood type A, blood type B was associated with statistically significant reduced risk of all cancers (HR, 0.91, 95% CI:0.84, 0.99. Both blood types B and AB were associated with significantly lower risk of gastrointestinal cancer and colorectal cancer, respectively. Blood type B was also associated with significantly lower risk of stomach cancer and bladder cancer, while blood type AB was associated with significantly increased risk of liver cancer. By histological type, blood types B and AB were associated with lower risk of epidermoid carcinoma and adenocarcinoma, but were not associated with risk of sarcoma, lymphoma, leukemia or other cell types of cancer. The findings of this study support a role of genetic traits related to ABO blood type in the development of cancers in the gastrointestinal and urinary tracts.

    Full Text Available In the book "Eat Right For Your Type" the author Peter J. D'Adamo writes that the O blood type was the first blood type to appear in humans and affirms that the blood groups are the key to the immune system. Some recent phylogenetic network studies in humans and non-human primates implies that the A gene represents an ancient form of the ABO genes. Relationships between blood groups and infectious and noninfectious diseases and immunodeficiency abnormalities have also been reported in the literature. As D'Adamo's propositions seem to be in opposition with the current knowledge, we present in this paper some comments about the genetics and the evolution of the ABO blood group genes and some links between this blood system and the functioning of the immune system.Peter J. D'Adamo, autor do livro "Eat Right For Your Type", escreve que o grupo O representa o primeiro tipo sangüíneo que surgiu nos humanos e também afirma que os grupos sangüíneos constituem as bases do sistema imune. Recentes estudos filogenéticos realizados em primatas humanos e não humanos estabeleceram que o gene A representa a forma ancestral dos genes que ocupam o locus ABO. Associações entre os grupos sangüíneos ABO, doenças infecciosas, não infecciosas e imunodeficiências também foram relatadas. Diante das proposições do autor, as quais se opõem às informações resultantes de recentes estudos moleculares e filogenéticos, nossa intenção é apresentar algumas reflexões sobre a genética e a evolução dos genes do sistema ABO e as conexões deste sistema com o sistema imune.

    Background: Blood is man's complete and unchangeable identity. The ABO and Rh groups are recognised as major and clinically significant blood groups. Blood group antigens are not only important in relation to blood transfusion and organ transplantation, but also have been utilised in genetic research, anthropology and tracing ancestral relation of humans. The objective the present study is to examine the blood group antigens in infertile men for assessing the relationship to male infertility and to know the frequency of various blood groups among infertile males in our population. Method: A total of 1,521 patients along with 460 proven fathers as controls were recruited for the present study from both rural and urban areas of Pakistan and referred to Department of Reproductive Physiology/Health, Public Health Divisions, NIH, Islamabad, during 2002 to 2006. Blood grouping (ABO) and Rhesus factors (Rh) was done by the antigen antibody agglutination test. Results: Overall distribution of blood groups in the studied population of 1,521 subjects was 35.50%, 28.27%, 26.89% and 9.34% for blood groups O, B, A and AB respectively. The ratio of control to patient was 1:3.3. Conclusions: The present preliminary study revealed that in our population the prevalence of male infertility in blood group O is invariably higher than in all other ABO blood groups, showing a strong relationship between blood group O and male infertility.

    BACKGROUND: Erycard 2.0 is a “point-of-care” device that is primarily being used for patient blood grouping before transfusion. MATERIALS AND METHODS: Erycard 2.0 was compared with conventional slide technology for accuracy and time taken for ABO and Rh forward grouping result with column agglutination technology (CAT) being the gold standard. Erycard 2.0 as a device was also evaluated for its stability under different storage conditions and stability of result till 48 h. In addition, grouping of hemolyzed samples was also tested with Erycard 2.0. Ease of use of Erycard 2.0 was evaluated with a survey among paramedical staff. RESULTS: Erycard 2.0 demonstrated 100% concordance with CAT as compared with slide technique (98.9%). Mean time taken per test by Erycard 2.0 and slide technique was 5.13 min and 1.7 min, respectively. After pretesting storage under different temperature and humidity conditions, Erycard 2.0 did not show any deviation from the result. The result did not change even after 48 h of testing and storage under room temperature. 100% concordance was recorded between pre- and post-hemolyzed blood grouping. Ease of use survey revealed that Erycard 2.0 was more acceptable to paramedical staff for its simplicity, objectivity, and performance than conventional slide technique. CONCLUSION: Erycard 2.0 can be used as “point-of-care” device for blood donor screening for ABO and Rh blood group and can possibly replace conventional slide technique. PMID:29403211

    Ovarian reserve reflects both the quantity and quality of oocytes available for procreation, and is affected by many known and unknown factors. ABO blood type is related to a number of infertility processes, but it is unclear whether and how ABO blood type affects ovarian reserve. Here, we explored the relationship between ABO blood type and ovarian reserve in Chinese women with subfertility. Day-3 serum follicle-stimulating hormone (FSH) levels and blood type were examined in 14,875 women who underwent IVF or ICSI treatment. Blood type proportions in the patient population were as follows: 30.98% type A, 24.54% type B, 7.57% type AB, and 36.91% type O. A higher percentage of women with diminished ovarian reserve (DOR) were blood type O, while a lower percentage had the B antigen (B and AB). Multiple logistic regression analysis revealed that blood type O was associated with a greater risk of DOR than blood type B and B antigen-positive types. By contrast, the B antigen (B and AB) was associated with a lower incidence of DOR than blood type O. These results suggest that blood type O is a risk factor for DOR while the B antigen (blood type B or AB) is a protective factor for ovarian reserve in Chinese women with subfertility. Further studies are needed to confirm this effect and identify the underlying mechanisms.

    Following publication of guidelines on routine preoperative tests, the French Society of Anaesthesiology and Intensive Care (SFAR), in association with French national public health insurance, conducted a survey to evaluate adherence to guidelines and the economic consequences. Using the French Hospital Discharge Database and National Health Insurance Information system, tests performed during the 30 days before surgery were analysed for two situations: (1) standard laboratory coagulation tests and ABO blood typing in children able to walk and scheduled for tonsillectomy/adenoidectomy; and (2) ABO blood typing in adults before laparoscopic cholecystectomy, thyroidectomy, lumbar discectomy or breast surgery. Guidelines do not recommend any preoperative tests in these settings. Between 2013 and 2015, a coagulation test was performed in 49% of the 241 017 children who underwent tonsillectomy and 39% of the 133 790 children who underwent adenoidectomy. A similar pattern was observed for ABO blood typing although re-operation rates for bleeding on the first postoperative day were very low (0.12-0.31% for tonsillectomy and 0.01-0.02% for adenoidectomy). Between 2012 and 2015, ABO blood typing was performed in 32-45% of the 1 114 082 patients who underwent one of the four selected procedures. The transfusion rate was very low (0.02-0.31%). The mean cost for the four procedures over the 4 yr period was €5 310 000 (sd €325 000). Standard laboratory coagulation tests and ABO blood typing are still routinely prescribed before surgery and anaesthesia despite current guidelines. This over-prescription represents a high and unnecessary cost, and should therefore be addressed. © The Author 2017.

    The prognostic significance of ABO blood type for lymphoma is largely unknown. We evaluated the prognostic role of ABO blood type in patients with extranodal natural killer (NK)/T-cell lymphoma (ENKTL). We retrospectively analyzed clinical data of 697 patients with newly diagnosed ENKTL from three cancer centers. The prognostic value of ABO blood type was evaluated using Kaplan-Meier curves and Cox proportional hazard models. The prognostic values of the International Prognostic Index (IPI) and the Korean Prognostic Index (KPI) were also evaluated. Compared with patients with blood type O, those with blood type non-O tended to display elevated baseline serum C-reactive protein levels (P = 0.038), lower rate of complete remission (P = 0.005), shorter progression-free survival (PFS, P 60 years (P KPI in distinguishing between the intermediate-to-low- and high-to-intermediate-risk groups. ABO blood type was an independent predictor of clinical outcome for patients with ENKTL.

The retrospective analysis involved 35,479 women who underwent in vitro fertilization and embryo transfer (IVF-ET) cycles between 2006 and 2012. None. The association between ABO blood types and diminished ovarian reserve (DOR). Among 35,479 Chinese women, 11,395 (32.12%) had blood type B, 10,583 (29.83%) had blood type O, 9,861 (27.79%) had blood type A, and 3,640 (10.26%) had blood type AB. There was a statistically significantly higher percentage of blood type O among those with follicle-stimulating hormone (FSH) levels ≤10 IU/L compared with those with FSH levels >10 IU/L. Conversely, among the women with DOR, there was statistically significantly higher percentage of those with blood types B and AB. Blood type A was not associated with DOR occurrence. Multivariate logistic regression analysis showed that blood type O was statistically significantly less often associated with DOR occurrence, whereas the B antigen (blood type B or AB) was statistically significantly associated with an increased risk of DOR. Our results have shown that there is an association between ABO blood type and DOR occurrence in Chinese women. Women with blood type O were statistically significantly less likely to have DOR, whereas those with B antigen (blood type B or AB) were statistically significantly more likely to have DOR. Blood type A was not associated with ovarian reserve. Copyright © 2014. Published by Elsevier Inc.

    Full Text Available In this study, we demonstrate a long-range surface plasmon resonance (LR-SPR biosensor for the detection of whole cell by captured antigens A and B on the surface of red blood cells (RBCs as a model. The LR-SPR sensor chip consists of high-refractive index glass, a Cytop film layer, and a thin gold (Au film, which makes the evanescent field intensity and the penetration depth longer than conventional SPR. Therefore, the LR-SPR biosensor has improved capability for detecting large analytes, such as RBCs. The antibodies specific to blood group A and group B (Anti-A and Anti-B are covalently immobilized on a grafting self-assembled monolayer (SAM/Au surface on the biosensor. For blood typing, RBC samples can be detected by the LR-SPR biosensor through a change in the refractive index. We determined that the results of blood typing using the LR-SPR biosensor are consistent with the results obtained from the agglutination test. We obtained the lowest detection limits of 1.58 × 105 cells/ml for RBC-A and 3.83 × 105 cells/ml for RBC-B, indicating that the LR-SPR chip has a higher sensitivity than conventional SPR biosensors (3.3 × 108 cells/ml. The surface of the biosensor can be efficiently regenerated using 20 mM NaOH. In summary, as the LR-SPR technique is sensitive and has a simple experimental setup, it can easily be applied for ABO blood group typing.

    Blood group antigens represent polymorphic traits inherited among individuals and populations. At present, there are 34 recognized human blood groups and hundreds of individual blood group antigens and alleles. Differences in blood group antigen expression can increase or decrease host susceptibility to many infections. Blood groups can play a direct role in infection by serving as receptors and/or coreceptors for microorganisms, parasites, and viruses. In addition, many blood group antigens facilitate intracellular uptake, signal transduction, or adhesion through the organization of membrane microdomains. Several blood groups can modify the innate immune response to infection. Several distinct phenotypes associated with increased host resistance to malaria are overrepresented in populations living in areas where malaria is endemic, as a result of evolutionary pressures. Microorganisms can also stimulate antibodies against blood group antigens, including ABO, T, and Kell. Finally, there is a symbiotic relationship between blood group expression and maturation of the gastrointestinal microbiome. Copyright © 2015, American Society for Microbiology. All Rights Reserved.

    To investigate the association between ABO blood type and live-birth outcomes in patients undergoing IVF with day 5 single-embryo transfer (SET). Retrospective cohort study. University-affiliated center. Normal responders, blood type and live birth, while controlling for confounders. Odds ratios (OR) with 95% confidence intervals (CI) for live birth were estimated. A total of 2,329 patients were included. The mean age of the study cohort was 34.6 ± 4.78 years. The distribution of blood types was as follows: A = 897 (38.5%); B = 397 (17.0%); AB = 120 (5.2%); and, O = 1,915 (39.3%) patients. There was no difference in the baseline demographics, ovarian stimulation, or embryo quality parameters between the blood types. The unadjusted ORs for live birth when comparing blood type A (referent) with blood types B, AB, and O were 0.96 (95% CI, 0.6-1.7), 0.72 (95% CI, 0.4-1.2), and 0.96 (95% CI. 0.6-1.7), respectively. The adjusted ORs for live birth remained not significant when comparing blood type A to blood types B, AB, and O individually. No difference in birth weight or gestational age at delivery was noted among the four blood types. Our findings suggest that ABO blood type is not associated with live-birth rate, birth weight, or gestational age at delivery in patients undergoing IVF with day 5 SET.

    To assess the effect of blood type on survival outcomes and adverse events (AEs) in patients treated with tyrosine kinase inhibitors (TKIs) for metastatic renal cell carcinoma (mRCC). Patients who received TKIs as first-line therapy for mRCC between 2008 and 2015 at our hospital were included in the study (n = 136). Patients were divided into 2 groups based on their blood type as O and non-O. Survival outcomes and AEs were compared according to blood type. Cox regression models were used for univariate and multivariate survival analyses. Of the 136 patients, 34 (25%) and 102 (75%) had O and non-O blood types, respectively. Blood type O was associated with an increased number of disease sites. There were no differences between the 2 groups with respect to other baseline characteristics. The progression-free survival in patients with O and non-O blood types was 12.1 and 11.6 months, respectively; the overall survival was 34.4 and 24.8 months, respectively. On univariate and multivariate analyses, the ABO blood type was not a significant prognostic factor for progression-free survival or overall survival. Furthermore, the incidences of serious AEs were similar in the 2 blood groups. ABO blood type was not associated with survival outcomes or incidences of serious AEs in mRCC patients treated with TKIs. However, blood type O may be associated with an increased number of disease sites. Copyright © 2017. Published by Elsevier Inc.

    Full Text Available Blood grouping is a vital test in pre-transfusion testing. Both tube and gel agglutination assays are used for ABO grouping. The main object of this study was to compare ABO grouping and D typing on tube and gel agglutination assay in order to assess the efficacy of each technique. A total of 100 healthy blood donors irrespective of age and sex were included in this study. Results showed that there is no significant difference between these two techniques. However, in 10 samples it was detected that the reaction strength in serum ABO grouping by gel agglutination assay is varied by only one grade when compared to tube agglutination assay. Due to numerous positive effects of gel assay it is more beneficial to implement this technique in the setups where blood banks bear heavy routine work load.

    Background. ABO hemolytic disease of the newborn is the most common hemolytic consequence of maternofetal blood group incompatibility restricted mostly to non-group-O babies of group O mothers with immune anti-A or anti-B antibodies. Aim. We estimated the risk of ABO HDN with view to determining need for routine screening for ABO incompatibility between mother and fetus. Materials and Methods. Prevalence of ABO blood group phenotypes in blood donors at the donor clinic of the Lagos University Teaching Hospital and arithmetic methods were used to determine population prevalence of ABO genes. We then estimated proportion of pregnancies of group O mothers carrying a non-group-O baby and the risk that maternofetal ABO incompatibility will cause clinical ABO HDN. Results. Blood from 9138 donors was ABO typed. 54.3%, 23%, 19.4%, and 3.3% were blood groups O, A, B, and AB, respectively. Calculated gene frequencies were 0.1416, 0.1209, and 0.7375 for A, B, and O genes, respectively. It was estimated that 14.3% of deliveries will result in a blood group O woman giving birth to a child who is non-group-O. Approximately 4.3% of deliveries are likely to suffer ABO HDN with 2.7% prone to suffer from moderately severe to severe hemolysis. PMID:26491605

    ABO blood typing in pre-transfusion testing is a major component of the high workload in blood banks that therefore requires automation. We often experienced discrepant results from an automated system, especially weak serum reactions. We evaluated the discrepant results by the reference manual method to confirm ABO blood typing. In total, 13,113 blood samples were tested with the AutoVue system; all samples were run in parallel with the reference manual method according to the laboratory protocol. The AutoVue system confirmed ABO blood typing of 12,816 samples (97.7%), and these results were concordant with those of the manual method. The remaining 297 samples (2.3%) showed discrepant results in the AutoVue system and were confirmed by the manual method. The discrepant results involved weak serum reactions (serum reactions, samples from patients who had received stem cell transplants, ABO subgroups, and specific system error messages. Among the 98 samples showing ≤1+ reaction grade in the AutoVue system, 70 samples (71.4%) showed a normal serum reaction (≥2+ reaction grade) with the manual method, and 28 samples (28.6%) showed weak serum reaction in both methods. ABO blood tying of 97.7% samples could be confirmed by the AutoVue system and a small proportion (2.3%) needed to be re-evaluated by the manual method. Samples with a 2+ reaction grade in serum typing do not need to be evaluated manually, while those with ≤1+ reaction grade do.

    Bone marrow ABO incompatible transplantations require graft manipulation prior to infusion to avoid potentially lethal side effects. We analyzed the influence of pre-manipulation factors (temperature at arrival, transit time, time of storage at 4°C until processing and total time from collection to red blood cell depletion) on the graft quality of 21 red blood cell depletion procedures in ABO incompatible pediatric transplants. Bone marrow collections were processed using the Spectra Optia ® (Terumo BCT) automated device. Temperature at arrival ranged between 4°C and 6°C, median transit time was 9.75h (range 0.33-28), median time of storage at 4°-6°C until processing was 1.8h (range 0.41-18.41) and median time from collection to RBC depletion was 21h (range1-39.4). Median percentage of red blood cell depletion was 97.7 (range 95.4-98.5), median mononuclear cells recovery was 92.2% (range 40-121.2), median CD34+ cell recovery was 93% (range 69.9-161.2), median cell viability was 97.7% (range 94-99.3) and median volume reduction was 83.9% (range 82-92). Graft quality was not significantly different between BM units median age. Our preliminary data show that when all good manifacturing practices are respected the post-manipulation graft quality is excellent also for those units processed after 24h.

    INTRODUCTION: Kidney transplantation is the optimal treatment for many patients with end-stage renal disease (ESRD). Due to shortage of donor kidneys in Denmark, there is a need to expand the possibilities for donation. At the Odense University Hospital (OUH), we have introduced ABO......-incompatible kidney transplantation. We used antigenspecific immunoadsorptions to remove blood group antibodies and anti-CD20 antibody (rituximab) to inhibit the antibody production. The aim of introducing the ABO-incompatible kidney transplantation at the OUH was to increase the rate of living donor kidney...... transplantation without increasing rejection or mortality rates. MATERIAL AND METHODS: Retrospective evaluation. Eleven patients received ABO-incompatible kidney transplantation. The patients were followed for 3-26 months. RESULTS: One patient had an antibody-mediated rejection, one patient suffered T...

  1. Immunodetection of Helicobacter sp. and the associated expression of ABO blood group antigens in the gastric mucosa of captive and free-living New World primates in the Amazon region

    Délia Cristina Figueira Aguiar

    2011-12-01

    Full Text Available The histo-blood group ABH antigens were first described in humans. These antigens are only present on erythrocytes from great apes and humans, while in more primitive animals they are found in tissues and body fluids. The ABH antigens are mainly distributed in tissues exposed to the external environment and potentially serve as ligands for pathogens or inhibitors of tissue connections. The objective of this paper was two-fold: (i to determine the presence of Helicobacter sp. in the gastric mucosa of 16 captive and 24 free-living New World monkeys and (ii to evaluate the presence of histopathological alterations related to bacterial infection and the associated expression of ABH antigens in the tissue. Stomach tissues from 13 species of monkey were assessed using haematoxylin-eosin and modified Gram staining (Hucker methods. An immunohistochemical analysis of the tissue revealed the presence of infectious bacteria that were characteristic of the genus Helicobacter sp. The results demonstrate that various species of monkey might be naturally infected with the Helicobacter sp. and that there is an increased susceptibility to infection. This study serves as a comparative analysis of infection between human and non-human primates and indicates the presence of a new species of Helicobacter.

    Complement C4d deposition in graft capillaries has been reported to be associated with antibody-mediated rejection in kidney and other solid organ transplantation. The correlation of C4d deposits and humoral rejection in liver transplants, however, is not well understood. We investigated the C4d immunostaining pattern in 34 patients whose liver biopsy was taken within the first 3 postoperative weeks for suspected acute rejection after ABO blood type-incompatible liver transplantation. The staining pattern was classified as positive (portal stromal staining), indeterminate (endothelial staining only), and negative (no staining). Positive C4d immunostaining was seen in 17 (50%) patients and was significantly associated with high (x64 or more) postoperative antidonor A/B antibody (immunoglobulin M (IgM)) titers (88 vs. 35%, P = 0.002) and poorer overall survival rate (41 vs. 88%, P = 0.007). Ten of 11 (91%) cases with histological acute humoral rejection (periportal edema and necrosis (PEN) or portal hemorrhagic edema) were positive for C4d, all of which showed high postoperative antibody titers. The other histologies associated with C4d positivity was purulent cholangitis (n = 4), coagulative hepatocyte necrosis (n = 1), acute cellular rejection (n = 1), and hepatocanalicular cholestasis (n = 1). Full clinical recovery was observed in only 6 of 17 (35%) C4d-positive patients, and tended to be associated with a lower rejection activity index (RAI). In conclusion, our study indicates that C4d deposits in the portal stroma can be a hallmark of acute humoral rejection in ABO-incompatible liver transplantation, and allograft damage can be reversible in a minority of cases.

    Full Text Available Background/Aim. Due to improved methods for removal of ABO isoagglutinins and novel immunosuppressive protocols, short and long term outcome in blood group incompatible is similar to blood group compatible kidney transplantation. The aim of this study was to determine the efficacy of our original method for removal of ABO isoagglutinins from the blood in ABO-incompatible kidney allograft recipients. Method. Between 2006 and 2008 twelve patients were transplanted from ABO incompatible living donors. Titers of ABO isoagglutinins were 4-128 (IgG. Immunosuppressive therapy started 14 days before kidney transplantation with rituximab, followed by a triple therapy (prednisone + tacrolimus + mycophenolate mofetil and the first plasma exchange (PE procedure, in which one plasma volume was substituted with albumin and saline on day 7 before transplantation. For selective extracorporeal immunoadsorption, the removed plasma was mixed with donor blood type filtered red blood cells, centrifuged and the supernatant separated and preserved. In the next PE procedure, the removed plasma was replaced with immunoadsorbed plasma, and so on. Titers of ABO agglutinins, renal allograft function and survival were followed-up. Results. The pre-transplant treatment consisting of 1-5 PE procedures and immunosuppressive therapy resulted in target ABO agglutinins titers below 4. During a 10-24 month follow-up three patients had an early acute rejection, one patient acute rejection and hemolytic anemia, two patients surgical complications and one of them lost his graft. In the post-transplant period, the titers of ABO antibodies remained below 4. All the patients had stable kidney allograft function with mean serum creatinine ±SD of 129 ± 45 μmol/l at the end of the study. Conclusion. Our method for removal of ABO antibodies was effective in a limited series of patients and short-term follow-up.

    Objective. The aim of the study is to investigate the possible associations between the blood groups ABO and Rhesus systems and the presence of keloids in patients with black skin. Method. This case-control study was conducted between September 2007 and August 2011 comparing dermatologic outpatients with keloids to matched controls recruited in preanesthetic consultation at Tokoin Teaching Hospital of Lomé (Togo). Results. The distribution of different ABO blood groups and Rhesus blood groups in both groups (cases versus controls) was not significantly different. This distribution of different blood groups was superimposed on the general population of blood donors at the National Blood Transfusion Center of Lomé. Univariate analysis between each blood group and the presence of keloid does not yield any statistically significant association between blood groups and presence of keloids in the subjects. Conclusion. The study shows no significant association between blood groups and the presence of keloids in our patients. Further investigation needs to be conducted to elucidate this hypothesis further by conducting multicenter studies of several ethnic groups.

    This study was purposed to investigate the incidence and the model of ABO hemolytic disease in newborn (ABO-HDN) and the results of the three hemolysis test, so as to provide the evidences for clinical diagnosis and therapy. A total of 227 cases of maternal-fetal ABO incompatibility from January 2013 to October 2013 in the First Affiliated Hospital of Xiamen University were enrolled in the study. The ABO blood group of newborn and mother was detemined and three hemolysis tests (direct antiglobulin test, free antibody test, RBC antibody release test) were performed. The results indicated that in 227 cases of ABO incompatible pregnancies,186 cases were ABO-HDN (81.94%). There was no significant difference in the incidence between O-A and O-B incompatible pregnancies (P > 0.05). The positive ratio of direct antiglobulin test, free antibody test and RBC antibody release test were 59.14% (110/186), 84.78% (156/186) and 94.62% (176/186) respectively. It is concluded that the incidence of ABO-HDN is high. The main models of ABO-HDN were O-A and O-B. There was no significant difference in the incidence between O-A and O-B incompatible pregnancies. Three hemolysis tests are high sensitivity and are helpful in early diagnosis and early treatment of HDN.

    Full Text Available AB0 blood groups are inherited markers on blood cells. Since their discovery, there were numerous attempts to be attributed a wide variety of biological functions they don’t possess. The purpose of this article is primarily to inform the professional, as well as lay public that the theory of healthy nutrition based on AB0 blood groups represents nothing more than a pseudoscience used for mass exploitation and commercial purposes. ABO blood groups were attributed such characteristics by naturopathic doctor Peter D'Adamo, who on the basis of false methods and erroneous assumptions wrote a bestseller "Eat Right For Your Type". It claims that the blood groupsAB0 represent a "key to the functioning of our immune system" and that the blood group based diet represents a “key to the health of every man”. As in the case of nutrition based on the ABO blood groups, the scientific knowledge in the field of immunohematology is misused to mislead the lay public, we are obliged to explain the real meaning and the role of blood groups in health and disease, the misuse of blood groups in relation to healthy nutrition.

    The necessity of detection of other than the classical major histocompatibility complex (MHC) and MHC class I-related chain A (MICA) directed antibodies prior to organ transplantation has already been repeatedly reported. A commercial flow cytometric endothelial crossmatch (CM) using isolated peripheral blood tie-2 positive cells provides a tool to detect non-MHC antibodies in addition to antibodies directed to MHC class I and II. The vast majority of circulating tie-2 positive cells expresses HLA-DR but not the A, B blood group antigens. Tie-2 cells are circulating surrogate endothelial cells. In this retrospective study we evaluated the endothelial CM in 51 renal transplantations, 30 with ABO compatible grafts and 21 with ABO incompatible grafts. Fifteen of the ABO compatible recipients (group A) developed unexplained rejection episodes (RE) while the remaining 15 had no RE (group B). Five cases of group A and none of group B had a positive tie-2 CM before transplantation (p=0.042). A positive tie-2 CM was also correlated with graft failure in ABO compatible transplants (p=0.02). No significant correlation was found between a positive pre-transplant tie-2 CM and RE in the ABO incompatible group. This study strongly suggest that a positive tie-2 CM may predict post-transplantation complications in ABO compatible grafts while negative reactions are not predictive. The test is not significantly correlated with RE in ABO incompatible grafts possibly due to applied desensitization. Copyright © 2013 American Society for Histocompatibility and Immunogenetics.

    Lung cancer, the leading cause of cancer deaths, is divided into 2 main classes based on its biology, therapy and prognosis: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). Many cases are at an advanced stage at diagnosis, which is a major obstacle to improving outcomes. It is important to define the high risk group patients for early diagnosis and chance of cure. Blood group antigens are chemical components on erythrocyte membranes but they are also expressed on a variety of epithelial cells. Links between ABO blood groups with benign or malignant diseases, such as gastric and pancreas cancers, have been observed for a long time. In this study, we aimed to investigate any possible relationship between lung cancer histological subtypes and ABO-Rh blood groups. The files of 307 pathologically confirmed lung cancer patients were were reviewed retrospectively. Cases with a serologically determined blood group and Rh factor were included and those with a history of another primary cancer were excluded, leaving a total of 221. The distribution of blood groups of the lung cancer patients were compared with the distribution of blood groups of healthy donors admitted to the Turkish Red Crescent Blood Service in our city in the year 2012. There was no significant difference between patients with lung cancer of either type and the control group in terms of distribution of ABO blood groups and Rh factor (p: 0.073). There was also no relationship with non small cell cancer histological subtypes. In this study, we found no relationship between the ABO-Rhesus blood groups and NSCLC and SCLC groups. To our knowledge this is the first analysis of ABO blood groups in SCLC patients.

  17. Transfusion reaction in a case with the rare Bombay blood group

    Full Text Available Bombay phenotype is extremely rare in Caucasian with an incidence of 1 in 250,000. When individuals with the Bombay phenotype need blood transfusion, they can receive only autologous blood or blood from another Bombay blood group. Transfusing blood group O red cells to them can cause a fatal hemolytic transfusion reaction. In this study, we report a case with the rare Bombay blood group that was misdiagnosed as the O blood group and developed a hemolytic transfusion reaction. This highlights the importance of both forward and reverse typing in ABO blood grouping and standard cross-matching and performing standard pretransfusion laboratory tests in hospital blood banks.

    Every person has certain features that make them radically distinct from others. One such feature is lip prints. Lip prints remain the same throughout life and are uninfluenced by injuries, diseases, or environmental changes. Different individuals have specific blood groups according to the various antigen-antibody reactions in their bloodstream. To determine the distribution of different patterns of lip prints among subjects having different ABO and Rh blood groups. To determine the correlation between respective characteristics of subjects. In this study, lip prints were obtained from 122 subjects (62 males and 60 females), and associated blood-group matching was performed to determine the predominant lip print type and to determine any correlation between lip print types and blood groups. Tsuchihashi's classification of type I (complete vertical grooves), type I' (incomplete vertical grooves), type II (forking grooves), type III (intersecting grooves), type IV (reticular grooves), and type V (indeterminate grooves) was used to compare with the ABO and Rh blood grouping systems. No correlation was found between lip prints and blood groups. No significant correlation exists between blood group and lip prints. Lip prints play a vital role in identification because they are unique.

    Over the last decade, we have witnessed an incredible growth in the amount of available genotype data due to high throughput sequencing (HTS) techniques. This information may be used to predict phenotypes of medical relevance, and pave the way towards personalized medicine. Blood phenotypes (e.g. ABO and Rh) are a purely genetic trait that has been extensively studied for decades, with currently over thirty known blood groups. Given the public availability of blood group data, it is of interest to predict these phenotypes from HTS data which may translate into more accurate blood typing in clinical practice. Here we propose BOOGIE, a fast predictor for the inference of blood groups from single nucleotide variant (SNV) databases. We focus on the prediction of thirty blood groups ranging from the well known ABO and Rh, to the less studied Junior or Diego. BOOGIE correctly predicted the blood group with 94% accuracy for the Personal Genome Project whole genome profiles where good quality SNV annotation was available. Additionally, our tool produces a high quality haplotype phase, which is of interest in the context of ethnicity-specific polymorphisms or traits. The versatility and simplicity of the analysis make it easily interpretable and allow easy extension of the protocol towards other phenotypes. BOOGIE can be downloaded from URL http://protein.bio.unipd.it/download/.

  1. Blood group ascription as a genetic marker of hepatic hemangioma

    There is no single point of view on pathogenesis of hemangiomas. The authors investigated the ABO blood types in 52 patients with hepatic hemangiomas (Group 1) and 1000 control patients (Group 2). The character of changes in the liver was established by means of reontgenoradionuclide investigation methods. The study demonstrated 61.5 % of the A blood type among the patients of Group 1. This was significantly higher than in the Group 2 and representative groups from literature (P < 0.001). Taking into account that the cells of both blood and blood vessels are formed in embryos through the mesenchyma and the heritability of blood group antigens, it is supposed that the results obtained support the genetic determination theory of pathogenesis of hepatic hemangioamas

    Blood donation results in a substantial iron loss and subsequent mobilization from body stores. Chronic iron deficiency is a well-recognized complication of regular blood donation. The present study conducted to compare the level of serum ferritin, serum iron, total iron binding capacity (TIBC) and percentage transferrin saturation in different ABO and Rhesus type blood groups among the voluntary blood donors of Bangladesh. The present prospective study included 100 healthy voluntary donors attending at Department of Blood Transfusion, Dhaka Medical College, Dhaka between the periods of July 2013 to Jun 2014. From each donor 10mL venous blood sample was taken and divided into heparinized and non-heparinized tubes for determination of hemoglobin (Hb), hematocrit (Hct), serum iron (SI), total iron binding capacity (TIBC) and serum ferritin by standard laboratory methods. Percentage of transferrin saturation (TS) calculated from serum iron and TIBC. Data were analyzed with SPSS (version 16) software and comparisons between groups were made using student's t-test and one way ANOVA. In the present study mean±SD of age of the respondents was 27.2±6.5 years with a range of 18 to 49 years and 81.0% were male and 19.0% were female. Among the donors 18.0% had blood group A, 35.0% had blood group B, 14.0% had blood group AB and 33.0% had blood group O. Among the donors 91.0% had rhesus positive and 9.0% had rhesus negative. Donors with blood group O had lowest haemoglobin, serum iron and transferring saturation levels. Donors with blood group A had highest TIBC level. Donors with blood group B had lowest serum ferritin level. An independent samples 't' test showed statistically significant difference in serum ferritin and percentage transferrin saturation between blood group AB and blood group O and in percentage transferrin saturation between blood group B and blood group O. One way ANOVA showed that there is no significant difference in haemoglobin, serum iron, serum

    Background ABO blood type is an inherited trait associated with coagulation factor levels and vascular outcomes. Objectives To assess the association of blood type with stroke and whether blood type contributes to racial disparities in stroke in the United States. Patients and Methods The REasons for Geographic and Racial Differences in Stroke (REGARDS) Study recruited 30,239 participants between 2003-07. Using a case-cohort design, blood type was genotyped in 646 participants with stroke and a 1,104 participant cohort random sample. Cox models adjusting for Framingham stroke risk factors assessed the association of blood type with stroke. Results Over 5.8 years of follow-up, blood types A or B versus type O were not associated with stroke. Blood type AB versus O was associated with an increased risk of stroke (adjusted HR 1.83; 95% CI 1.01, 3.30). The association of blood type AB versus O was greater in those without diabetes (adjusted HR 3.33; 95% CI 1.61, 6.88) than those with diabetes (adjusted HR 0.49; 95% CI 0.17, 1.44) (p-interaction = 0.02). Factor VIII levels accounted for 60% (95% CI 11%, 98%) of the association of AB blood type and stroke risk. Conclusion Blood type AB is associated with an increased risk of stroke that is not attenuated by conventional stroke risk factors and factor VIII levels were associated with 60% of the association. While blood type AB is rare in the U.S. population, it is a significant stroke risk factor and may play an important role in stroke risk in these individuals. PMID:24444093

    The ABO blood group system is the most important blood group system in clinical practice. The relationship between Plasmodium falciparum and ABO blood groups has been studied for many years. This study was undertaken to investigate the abilities of different blood group erythrocytes to support in vitro growth of P. falciparum parasites. P. falciparum parasites of four different strains (3D7, 7G8, Dd2 and RKL9) were co-cultured with erythrocytes of blood group 'A', 'B', 'O' (n = 10 for each) and 'O(h)' (Bombay group) (n = 7) for 5 days. Statistically significant differences were observed on the fourth day among the mean percent parasitemias of 'O', non-'O' ('A' and 'B') and 'O(h)' group cultures. The parasitemias of four strains ranged from 12.23 to 14.66, 11.68 to 13.24, 16.89 to 22.3, and 7.37 to 11.27 % in 'A', 'B', 'O' and Bombay group cultures, respectively. As the expression of H antigen decreased from 'O' blood group to 'A' and 'B' and then to Bombay blood group, parasite invasion (percent parasitemia) also decreased significantly (p Ulex europaeus seeds. Mean percent parasitemia of lectin-treated cultures on the fourth day was significantly lower (p < 0.05) than that of non-treated cultures and was found to be similar with the mean percent parasitemia demonstrated by the Bombay group erythrocyte cultures, thus further strengthening the hypothesis.

    For desensitization of ABO-incompatible kidney transplant recipients we recently proposed nonantigen-specific immunoadsorption (IA) and rituximab. We now compared clinical outcomes of 34 ABO-incompatible living-donor kidney recipients who were transplanted using this protocol with that of 68 matched ABO-compatible patients. In addition, we analyzed efficacy and cost of nonantigen-specific as compared to blood group antigen-specific IA. Before desensitization, the median isoagglutinin titer of 34 ABO-incompatible patients was 1:64 (Coombs technique). Patients received a median of 7 preoperative IA treatments. Twenty-four patients had a median of 2 additional plasmapheresis treatments to reach the preoperative target isoagglutinin titer of 1:8 or less. After a median postoperative follow-up of 22 months, overall graft survival in the ABO-incompatible group was not significantly different from that in ABO-compatible patients (log-rank P = 0.20), whereas patient survival tended to be lower (log-rank P = 0.05). The incidence of rejection episodes was 15% in both groups. The ABO-incompatible kidney recipients had a higher incidence of BK virus replication (P = 0.04) and nephropathy (P = 0.01) and showed more often colonization with multidrug resistant bacteria (P = 0.02). In comparison to blood group antigen-specific IA, nonantigen-specific IA showed equal efficacy but was associated with reduction in cost. Clinical outcomes of ABO-incompatible patients desensitized with a nonantigen-specific IA device and rituximab do not differ from that of matched ABO-compatible patients although a trend toward reduced patient survival was noted. Special attention must be paid to the higher incidence of BK virus infection in recipients of ABO-incompatible grafts.

    This research is about gene distribution of ABO blood type system on the Dengue Hemorrhagic Fever (DHF) patients in the working area of Puskesmas Bonto Bangun, District of Rilau Ale, Bulukumba. This research aimed to determine the blood type which is most affected by DHF using ABO blood type system. In this research, there are 104 samples, 8 of them were attacked by DF and 96 were attacked by DHF. From the 96 patients of DHF, there were 38 patients with A-blood type, 17 patients with B-blood type, 36 patients with O-blood type and 5 patients of AB-blood type. The data were tested using genotype frequency test and the results showed that the percentage of A-homozygous blood type (IAIA) is 0:09%; A heterozygous blood type (IAIo) is 0:36%; B-homozygous blood type (IBIB) is 0.01%; B heterozygous blood type (IB Io) is 0.12%; AB blood type (IAIB) is 0.06% and O blood type (IoIo) is 12:36%. So the biggest frequency of genotype are IAIo (0.36%) and IoIo (0.36%). The results showed that O blood type gene is the most affected by DHF. Then continued by the regression test between blood type and DHF, it is obtained that the correlation value is 1 which indicated that there is a strong relationship.

GDM is not only associated with adverse pregnancy outcomes such as macrosomia, dystocia, birth trauma, and metabolic complications in newborns, but it is also a strong predictor of transitioning to overt DM postpartum. The association of ABO blood groups with DM has been observed before in several epidemiological and genetic studies and resulted with inconsistent findings, but still there are not enough studies in the literature about the association of ABO blood groups with GDM. In this study, we aimed at investigating any possible relationship between the ABO blood group system and GDM and also the transitioning of GDM to overt DM postpartum, in Turkey.Patients and methods: A total of 233 patients with GDM from Kayseri Training and Research Hospital between 2002 and 2012 were included in the study. The cases that have serologically determined blood groups and Rh factor in the hospital records were included in the study, and the patients with unknown blood groups were excluded. Patients were classified according to blood groups (A, B, AB, and O and Rh status (+/-.

    We report the use of bioactive paper for typing of secondary human blood groups. Our recent work on using bioactive paper for human blood typing has led to the discovery of a new method for identifying haemagglutination of red blood cells. The primary human blood groups, i.e., ABO and RhD groups, have been successfully typed with this method. Clinically, however, many secondary blood groups can also cause fatal blood transfusion accidents, despite the fact that the haemagglutination reactions of secondary blood groups are generally weaker than those of the primary blood groups. We describe the design of a user-friendly sensor for rapid typing of secondary blood groups using bioactive paper. We also present mechanistic insights into interactions between secondary blood group antibodies and red blood cells obtained using confocal microscopy. Haemagglutination patterns under different conditions are revealed for optimization of the assay conditions.

    Molecular genotyping of ABO blood group system has identified more than 60 "O" group alleles based on the single-nucleotide polymorphisms present in the ABO gene. Heterogeneity of O group alleles has been observed in various countries from South America, Europe, Middle East, and Asia. India is a vast country with more than 1300 million population which is divided into various ethnic and tribal groups. However, very little is known about the heterogeneity of O alleles in Indians. A total of 116 O group individuals from the mixed population of Mumbai, India, were enrolled in the present study. DNA was extracted using the standard phenol-chloroform method. The exons 6 and 7 of the ABO gene were genotyped by polymerase chain reaction-single-strand conformation polymorphism and/or DNA sequencing. The genotyping results were compared with our earlier findings. Overall, ten different genotypes were identified. Three rare alleles, namely, O05, O11, and O26 were seen in the mixed group category. These results suggest that there is an internal heterogeneity in the mixed group while Dhodias and Parsis, the groups which were screened earlier, seem to be more homogenous groups. An important piece of information emerges out from this study, that is, O01O02 genotype is expressing some selective force in population groups screened in India as well as many other groups worldwide. In the future, molecular genotyping of the ABO blood group system among different ethnic and tribal Indian groups would help in generating data to fill up the gaps in the molecular ABO map of the world.

    Full Text Available Background: ABO incompatibility hemolytic disease of the newborn is a common cause of clinical jaundice and causes two-thirds of the hemolytic disease in newborns. This study was undertaken to determine the frequency of ABO incompatibility hemolytic disease and its complications in newborns undergoing exchange transfusion.Methods: This prospective and descriptive study was performed in jaundiced newborn infants during a three-year period. Inclusion criteria were: maternal blood type O, newborn blood type A or B, rising indirect hyperbilirubinemia in the first two days of life, positive immunohematologic test for newborns and exchange transfusion. Exclusion criteria were: incomplete information, other accompanying diseases that induce hyperbilirubinemia. All newborn infants received phototherapy before and after exchange transfusion. We did not use intravenous immunoglobulin, hemoxygenase inhibitor drugs and blood products before exchange transfusion.Results: Double-volume exchange transfusion via umbilical cord catheter was performed in 96 patients, 19 (20% of whom suffered from ABO incompatibility. Of these 19 newborns, two-thirds (13 were preterm infants. The minimum level of serum bilirubin was 10 mg/dl and the maximum serum bilirubin level was 35 mg/dl. In six patients (32% serum bilirubin levels were >25mg/dl. The most common blood group was type A for newborns. Immunohematologic tests were positive in 84% of the mothers. ABO incompatibility hemolytic disease was the fourth and second most common reasons for blood exchange transfusion in preterm and term infants, respectively. Laboratory complications were more common than clinical complications. The etiology of 48% of the alloimmunization and 42% of the hemolytic disease in these newborns was ABO incompatibility.Conclusions: Mothers with blood group O and newborns with blood group A or B with positive immunohematologic tests in first hours of life are at high risk for hemolytic disease

The distributions of blood groups of the patients with GDM were compared with the distribution of blood groups of 17,314 healthy donors who were admitted to the Turkish Red Crescent Blood Service in our city in 2012. There was a significant difference between the patients with GDM and control group in terms of distribution of ABO blood groups. Blood group AB was found to be higher in the patients with GDM compared to the control group (P=0.029). When the patients were compared according to the development of DM, the ratio of group O was higher than others, while the

    Perioperative transfusions have been recently associated to poor outcomes as an indirect consequence of immune-hematological changes related to transfusion itself and blood type. We tested the role of blood transfusion on cancer-specific mortality (CSM) and overall mortality (OM), considering the effect of ABO system, Rh factor, and timing of transfusions. The study focused on 728 patients with bladder cancer treated with radical cystectomy at a single tertiary care referral center between January 1995 and August 2013 with complete ABO blood type information. Kaplan-Meier analysis was used to assess the effect of transfusions, stratified according to ABO type and Rh factor, on CSM and OM. The same endpoints were tested in Cox regression models, after adjusting for all available confounders. A total of 341 (46.8%), 277 (38.0%), 83 (11.4%), and 27 (3.7%) patients had blood type O, A, B and AB, respectively. Overall, 630 (86.5%) and 98 (13.5%) patients were Rh-and Rh+, respectively. At a median follow-up time of 65 months, 225 (30.9%) and 282 (38.7%) patients recorded CSM and OM, respectively. At univariable analyses, ABO blood type and Rh status were not associated to either CSM or OM (all P>0.2). Similar results were observed when ABO blood type and Rh factor were tested in multivariable models (all P>0.3). Conversely, Charlson score, preoperative hemoglobin, number of nodes removed, pathological T stage, and number of positive nodes were associated to both CSM and OM (all Pblood units in the postoperative period (P>0.05) was associated with an increase of CSM and OM. Although ABO type or Rh factor or both were associated with several adverse outcomes in many cancers, we were not able to confirm this association in bladder cancer. Based on our results, the effect of transfusion on survival is independent by ABO type but is associated to the timing of blood supply administration. Copyright © 2016 Elsevier Inc.

    Results And Discussion: Overall, ten different genotypes were identified. Three rare alleles, namely, O05, O11, and O26 were seen in the mixed group category. These results suggest that there is an internal heterogeneity in the mixed group while Dhodias and Parsis, the groups which were screened earlier, seem to be more homogenous groups. An important piece of information emerges out from this study, that is, O01O02 genotype is expressing some selective force in population groups screened in India as well as many other groups worldwide. Conclusion: In the future, molecular genotyping of the ABO blood group system among different ethnic and tribal Indian groups would help in generating data to fill up the gaps in the molecular ABO map of the world.

    Full Text Available Adult living donor liver transplantations (ALDLTs across the ABO blood group barrier have been reported in Asia, North Americas, and Europe, but not yet in Germany. Several strategies have been established to overcome the detrimental effects that are attached with such a disparity between donor and host, but no gold standard has yet emerged. Here, we present the first experiences with three ABO-incompatible adult living donor liver transplantations in Germany applying different immunosuppressive strategies. Four patient-donor couples were considered for ABO-incompatible ALDLT. In these patients, resident ABO blood group antibodies (isoagglutinins were depleted by plasmapheresis or immunoadsorption and replenishment was inhibited by splenectomy and/or B-cell-targeted immunosuppression. Despite different treatments ALDLT could safely be performed in three patients and all patients had good initial graft function without signs for antibody-mediated rejection (AMR. Two patients had long-term graft survival with stable graft function. We thus propose the feasibility of ABO-incompatible ALDLT with these protocols and advocate further expansion of ABO incompatible ALDLT in multicenter trials to improve efficacy and safety.

    Although 7 million copies of Eat Right 4 Your Type have been sold in >60 languages, there has been a lack of evidence supporting the "blood-type" diet hypothesis. The present study aimed to examine the validity of this diet in overweight adults. A total of 973 adults [mean ± SEM age: 44.6 ± 0.4 y; mean ± SEM body mass index (BMI; kg/m2): 32.5 ± 0.2; 758 women, 215 men] were participants of the Toronto Healthy Diet Study. A 1-mo, 196-item food-frequency questionnaire was used to determine dietary intakes before and after a 6-mo dietary intervention. Diet scores were calculated to determine relative adherence to each of the 4 blood-type diets as a secondary analysis. ABO blood group was determined by genotyping rs8176719 and rs8176746. ANCOVA was used to compare cardiometabolic risk factors across tertiles of diet scores. At baseline, individuals with a higher adherence score to the type A diet had lower diastolic blood pressure (tertile 3 compared with tertile 1: 70.9 ± 1.1 compared with 73.3 ± 1.1 mm Hg; P type B (tertile 3 compared with tertile 1: 100.8 ± 1.8 compared with 105.4 ± 1.7 cm; P type AB (tertile 3 compared with tertile 1: 101.2 ± 1.8 compared with 104.8 ± 1.7 cm; P type A and type B diets had greater reductions in BMI and waist circumference, respectively (P type O diet adherence showed decreases in both BMI and waist circumference (P blood-type diets and biomarkers of cardiometabolic disease in overweight adults, suggesting that the theory behind this diet is not valid This study was based on the data of a trial that was registered at www.clinicaltrials.gov as NCT00516620.

    To evaluate the association of ABO blood type with clinicopathologic outcomes and mortality among patients with urothelial carcinoma of the bladder treated with radical cystectomy (RC). We identified 2,086 consecutive patients who underwent RC between 1980 and 2008. Postoperative recurrence-free survival (RFS) and cancer-specific survival (CSS) were estimated using the Kaplan Meier method and compared with the log-rank test. Cox proportional hazards regression models were used to evaluate the association of ABO blood type with outcomes. A total of 913 (44%), 881 (42%), 216 (10%), and 76 (4%) patients had blood type O, A, B, and AB, respectively. Median postoperative follow-up among survivors was 11.0 years (interquartile range: 7.7-15.9y). Overall, 1,561 patients died, with 770 deaths attributable to bladder cancer. Non-O blood type was associated with significantly worse 5-year RFS (65% vs. 69%; P = 0.04) and/or CSS (64% vs. 70%; P = 0.02). In particular, among patients with≤pT2N0 disease, the 5-year RFS for those with non-O vs. O blood type was 75% vs. 82%, respectively (P = 0.002), whereas the 5-year CSS was 77% vs. 85%, respectively (P = 0.001). Moreover, on multivariable analysis, blood type A remained independently associated with an increased risk of cancer-specific mortality (hazard ratio = 1.22; P = 0.01). Non-O blood type, particularly blood type A, is associated with a significantly increased risk of death from bladder cancer among patients undergoing RC. If validated, the utility of a multimodal therapy approach, including perioperative chemotherapy, or more frequent postoperative surveillance in this cohort warrants further study.

    For many decades, hemagglutination has been the sole means to type blood donors. Since the first blood group gene cloning in the early 1990s, knowledge on the molecular basis of most red blood cell, platelet and neutrophil antigens brought the possibility of using nucleotide-based techniques to predict phenotype. This review will summarized methodologies available to genotype blood groups from laboratory developed assays to commercially available platforms, and how proficiency assays become more present. The author will also share her vision of the transfusion medicine future. The field is presently at the crossroads, bringing new perspectives to a century old practice. Copyright © 2014 Elsevier Ltd.

    ABO compatibility has been believed to be necessary in kidney transplantation (Ktx) to prevent acute antibody-mediated rejection. However, developments in immunosuppression and immunoadsorption techniques have overcome acute antibody-mediated rejection caused by ABO incompatibility. Herein, we have presented the first ABO-incompatible Ktx cases in Turkey. All recipients did not have an ABO-compatible donor but presented significant dialysis inadequacy due to vascular access problems. Five dialysis patients with blood groups O or B underwent kidney transplantation from living related donors of blood group type A1 or AB between march 23, 2007 and August 16, 2007. All patients received Rituximab (375 mg/m(2)) at 3-4 weeks before the Ktx. Additionally, we started tacrolimus (0.15 mg/kg), mycophenolate mofetil (2 × 1 g), and simvastatin (1 × 20 mg) 1 week before the operation. Immunoadsorption therapy employing a specific filter (Glycosorbs) to remove anti-A or anti-B antibodies was continued until the titers were 1/8 during the first postoperative week and >1/16 at the second postoperative week. We used 2 standard hemodialysis machines with a connection line to perform immunoabsorption and dialysis during the same session. Acute humoral and cellular rejection was not detected. During the follow-up 1 patient was lost due to a cardiovascular complication. Mean creatinine level was 1.1 ± 0.3 mg/dL. These first ABO-incompatible transplantation cases in Turkey suggest that this source may represent an effective approach to overcome the organ shortage. Copyright © 2012 Elsevier Inc.

    There is growing epidemiological and molecular evidence that ABO blood group affects host susceptibility to severe Plasmodium falciparum infection. The high frequency of common ABO alleles means that even modest differences in susceptibility could have a significant impact on the health of people living in malaria endemic regions. We performed an association study, the first to utilize key molecular genetic variation underlying the ABO system, genotyping >9000 individuals across three African populations. Using population- and family-based tests, we demonstrated that alleles producing functional ABO enzymes are associated with greater risk of severe malaria phenotypes (particularly malarial anemia) in comparison with the frameshift deletion underlying blood group O: case-control allelic odds ratio (OR), 1.2; 95% confidence interval (CI), 1.09-1.32; P = 0.0003; family-studies allelic OR, 1.19; 95% CI, 1.08-1.32; P = 0.001; pooled across all studies allelic OR, 1.18; 95% CI, 1.11-1.26; P = 2 x 10(-7). We found suggestive evidence of a parent-of-origin effect at the ABO locus by analyzing the family trios. Non-O haplotypes inherited from mothers, but not fathers, are significantly associated with severe malaria (likelihood ratio test of Weinberg, P = 0.046). Finally, we used HapMap data to demonstrate a region of low F(ST) (-0.001) between the three main HapMap population groups across the ABO locus, an outlier in the empirical distribution of F(ST) across chromosome 9 (approximately 99.5-99.9th centile). This low F(ST) region may be a signal of long-standing balancing selection at the ABO locus, caused by multiple infectious pathogens including P. falciparum.

    Port Harcourt is a cosmopolitan city consisting of several ethnic groupings such as Ikwerre, Ijaw, Igbo, Ogonis, Efik-Ibibio, Edo, Yoruba, Hausa and foreign nationals. ABO and Rhesus D antigens were screened in this cross-sectional study with the aim of generating data that would assist in the running of an efficient blood transfusion service for a cosmopolitan city as Port Harcourt. Blood donors were sampled and screened for ABO and Rhesus D antigens at three Health facilities within Port Harcourt: University of Port Harcourt Teaching Hospital, Braithwaite Memorial Hospital and Orogbum Health centre. A total of 936 blood donors were tested in this study. The results of the ABO screening shows that blood group O was the highest with 527 (56.30%) followed by blood group A, B and lastly AB with 212 (22.65%), 178 (19.02%) and 18(2.10%) respectively. The highest contribution to blood group O was from the Ibos with 220 (23.50%) while the Ijaws gave the highest contribution of Rhesus "D" antigen with 370 (39.53%), closely followed by the Igbos with 334 (0.43%). Rhesus negativity values in this study was 7.26% of which the highest contributors were also the Ijaws with 33 (3.53%) and Igbos with 27(2.89%). The increased demand for safe blood calls for an efficient Blood, Transfusion Service at the local, state and national levels. It is hoped that the data generated in this study would assist in the planning and establishment of a functional Blood service that would not only meet the ever increasing demand for blood products, but also play a vital role in the control of HIV/AIDS and . Hepatitis B global scourge.

    Full Text Available Aim: To find out the co-relation between polycystic ovary syndrome (PCOS with blood group & diet in South Indian females, between the age-group of (20-30 years. Objectives: Correlative analysis of ABO & Rh system, dietary habits & alcohol consumption with PCOS. Materials & Methods: 100 patients between (20-30 years, diagnosed with PCOS were selected. A standard PCOS questionnaire was given. Blood group & dietary status data were collected. Patients were grouped according to ABO & Rh system considering their diet & alcohol intake (p≤0.05 significant. Result: Our data revealed that the highest risk of PCOS was observed in females with blood group ‘O’ positive followed by ‘B’ positive who were on mixed diet & used to consume alcohol. Our study also suggests that Rh negative individuals didn’t show any association with PCOS. Conclusion: The results of our study suggest that ‘O’ positive females, are more prone to PCOS. Though the relative frequency of B positive individuals are more in India, females with blood group O positive are more susceptible to PCOS, contributing factors being mixed diet & alcohol intake. So, early screening of ‘O’ positive &‘B’ positive females of reproductive age-group in South-India, could be used as a measure for timely diagnosis of PCOS, better management &also prevention of complications. However, further research should be done to investigate the multifaceted mechanisms triggering these effects.

    Full Text Available The serious shortage of cadaveric organs has prompted the development of ABO-incompatible live donor renal transplantation. We report our experience of the initial two live donor ABO incompatible renal transplants at our hospital. The first patient was a 55-year-old type A female who received a kidney from her AB type husband. The second patient was a 27-year-old type O male who received renal transplantation from his type A father. Preconditioning immunosuppressive therapy in the two patients with tacrolimus, mycophenolate mofetil and methylprednisolone was started 7 days before transplantation. During the period of preconditioning, double filtration plasmapheresis (DFPP was employed to remove anti-A and -B antibodies. Laparoscopic splenectomy and renal transplantation were performed after the anti-donor ABO antibodies were reduced to a titer of 1:4. Rituximab, a humanized monoclonal anti-CD20 antibody, was administered to the second patient due to a rebound in the anti-A antibody titer during the preconditioning period. Under a tacrolimus-based immunosuppressive regimen, both patients recovered very well without any evidence of rejection. Serum creatinine levels were 1.0 and 1.4 mg/dL at 6 and 3 months after transplantation, respectively. These cases illustrate that with new immunosuppressive agents, DFPP and splenectomy, ABO-incompatible renal transplantation can be successfully conducted in end-stage renal disease patients whose only available live donors are blood group incompatible.

    Preeclampsia (PE) is a pregnancy-related disorder characterized by hypertension (HT) and proteinuria noticeable after 20 weeks of gestation. PE is now considered as a cardiovascular disease risk factor and a number of studies have shown that experiencing PE increases the prevalence of various cardiovascular risk factors, such as metabolic syndrome and HT. In this study, we aimed to investigate any possible relationship between the ABO/Rh blood group system and PE in Turkey. In the second part of the study, we examined the relationship between the ABO blood group system and development of HT after PE. A total of 250 patients with PE from Kayseri Training and Research Hospital between 2002 and 2012 were included in the study. Patients were classified according to blood groups (A, B, AB, and O) and Rh status (+/-). There was a significant difference between the patients with PE and the control group in terms of distribution of ABO blood groups and the percentage of group AB was found to be higher in patients with PE compared to the control group (P=0.029). The risk of developing PE was significantly higher in group AB than other blood groups (P=0.006). The risk of developing HT after PE was significantly higher in group O than other blood groups (P=0.004). In this study, we found that the patients with blood group AB have a higher risk for PE. The patients with PE of blood group O are at high risk of developing HT, and Rh factor was identified as another risk at this point and these patients should be closely followed postpartum.

    Transfusion of group O blood to non-O recipients, or transfusion of D- blood to D+ recipients, can result in shortages of group O or D- blood, respectively. This study investigated RBC utilization patterns at hospitals around the world and explored the context and policies that guide ABO blood group and D type selection practices. This was a retrospective study on transfusion data from the 2013 calendar year. This study included a survey component that asked about hospital RBC selection and transfusion practices and a data collection component where participants submitted information on RBC unit disposition including blood group and D type of unit and recipient. Units administered to recipients of unknown ABO or D group were excluded. Thirty-eight hospitals in 11 countries responded to the survey, 30 of which provided specific RBC unit disposition data. Overall, 11.1% (21,235/191,397) of group O units were transfused to non-O recipients; 22.6% (8777/38,911) of group O D- RBC units were transfused to O D+ recipients, and 43.2% (16,800/38,911) of group O D- RBC units were transfused to recipients that were not group O D-. Disposition of units and hospital transfusion policy varied within and across hospitals of different sizes, with transfusion of group O D- units to non-group O D- patients ranging from 0% to 33%. A significant proportion of group O and D- RBC units were transfused to compatible, nonidentical recipients, although the frequency of this practice varied across sites. © 2017 AABB.

    To determine the frequency of different blood groups among female medical students and to find the association of blood groups and body mass index with blood pressure. This cross-sectional study was performed at the University Medical and Dental College, Faisalabad, Pakistan, from March to April 2016, and comprised female medical students. Participants were divided into groups on the basis of their ABO blood groups and on body mass index criteria. Blood groups were determined by simple conventional slide method. Blood pressure was estimated by manual auscultatory technique with a mercury sphygmomanometer. Data was analysed usingSPSS20. There were 145 students with an overall mean age of18.4±0.75 years (range: 17-23 years). Blood group B was the predominant group 65(44.8%). Besides, 130(89.6%) subjects were rhesus positive and 23(53%) subjects of blood group O were pre-hypertensive. Multiple regression analysis indicated significant positive association of blood group O with both systolic and diastolic blood pressure (p=0.002, 0.001). However, subsequent logistic regression showed significant association only with diastolic blood pressure (p=0.001). Relative risk of pre-hypertension for obese (p=0.001) was greater than non-obese subjects. Body mass index was significantly associated with both systolic and diastolic blood pressure (p=0.004, 0.042). Blood group B was the most common blood group. Blood group O was associated with diastolic pre-hypertension, while body mass index was associated with both systolic and diastolic pre-hypertension.

    This study presents the results of an examination of 3 blood-group systems (ABO, Rhesus, and P1) and erythrocyte enzymes (ADA, AK, ALADH, PGD, SAHH, PGM1, PGM3, GPT, GOT, ACP, UMPK, ESD and GLO) in populations that reside in R. Macedonia. Four population samples from the Republic of Macedonia (129 Macedonians from Skopje, 98 Albanians from Skopje, 95 Aromanians from Krusevo, 102 Aromanians from Stip) were included in the study. A comparison of the obtained results with data from literature on other Balkan populations has been made. The results of the comparison of the studied alleles indicate relatively small genetic distances among the studied populations. The obtained dendrograms indicate a larger homogeneity in the large Balkan populations, and a manifest trend of separating the Aromanian population of the Stip region. A larger separation is characteristic in the Greek population of Thrace.

  12. Genetic and mechanistic evaluation for the mixed-field agglutination in B3 blood type with IVS3+5G>A ABO gene mutation.

    Full Text Available BACKGROUND: The ABO blood type B(3 is the most common B subtype in the Chinese population with a frequency of 1/900. Although IVS3+5G>A (rs55852701 mutation of B gene has been shown to associate with the development of B(3 blood type, genetic and mechanistic evaluation for the unique mixed-field agglutination phenotype has not yet been completely addressed. METHODOLOGY/PRINCIPAL FINDINGS: In this study, we analyzed 16 cases of confirmed B(3 individuals and found that IVS3+5G>A attributes to all cases of B(3. RT-PCR analyses revealed the presence of at least 7 types of aberrant B(3 splicing transcripts with most of the transcripts causing early termination and producing non-functional protein during translation. The splicing transcript without exon 3 that was predicted to generate functional B(3 glycosyltransferase lacking 19 amino acids at the N-terminal segment constituted only 0.9% of the splicing transcripts. Expression of the B(3 cDNA with exon 3 deletion in the K562 erythroleukemia cells revealed that the B(3 glycosyltransferase had only 40% of B(1 activity in converting H antigen to B antigen. Notably, the typical mixed-field agglutination of B(3-RBCs can be mimicked by adding anti-B antibody to the K562-B(3 cells. CONCLUSIONS/SIGNIFICANCE: This study thereby demonstrates that both aberrant splicing of B transcripts and the reduced B(3 glycosyltransferase activity contribute to weak B expression and the mixed-field agglutination of B(3, adding to the complexity for the regulatory mechanisms of ABO gene expression.

    To find out frequency of obesity in female University students in Faisalabad and to investigate its association with blood groups of ABO system. A cross sectional study was conducted with a sample size of 200 female University students, recruited from the Faisalabad based institutes from May 2017 to July 2017. Relevant information was taken by administering questionnaire. Height in meters and weight in kg were taken by stadiometer. BMI was calculated using formula BMI=weight in kg/height m 2 . Blood groups were determined by classic (antigen-antibody agglutination test). The data was analyzed through SPSS 20. Descriptive were presented as mean± SD and association of BMI with blood groups was assessed by regression analysis. P value ≤0.05 deemed statistically significant. Out of students, 192 attempted the questionnaire and participated in study (96% response rate), 30% of the 192 females were obese, distribution of ABO blood group showed 43%, followed by O, A and AB. 90% were Rh positive and 10% were Rh negative. Blood group O showed a trend towards obesity and blood group AB showed a trend towards lean body. The blood group O showed the significant positive association with obesity. Population with blood group O showed greatest susceptibility to be overweight and obese.

    The ABO blood group antigens are expressed on erythrocytes but also on endothelial cells, platelets and serum proteins. Notably, the ABO blood group of a malaria patient determines the development of the disease given that blood group O reduces the probability to succumb in severe malaria, compared to individuals of groups A, B or AB. P. falciparum rosetting and sequestration are mediated by PfEMP1, RIFIN and STEVOR, expressed at the surface of the parasitized red blood cell (pRBC). Antibodies to these antigens consequently modify the course of a malaria infection by preventing sequestration and promoting phagocytosis of pRBC. Here we have studied rosetting P. falciparum and present evidence of an immune evasion mechanism not previously recognized. We find the accessibility of antibodies to PfEMP1 at the surface of the pRBC to be reduced when P. falciparum forms rosettes in blood group A RBC, as compared to group O RBC. The pRBC surrounds itself with tightly bound normal RBC that makes PfEMP1 inaccessible to antibodies and clearance by the immune system. Accordingly, pRBC of in vitro cloned P. falciparum devoid of ABO blood group dependent rosetting were equally well detected by anti-PfEMP1 antibodies, independent of the blood group utilized for their propagation. The pathogenic mechanisms underlying the severe forms of malaria may in patients of blood group A depend on the ability of the parasite to mask PfEMP1 from antibody recognition, in so doing evading immune clearance.

    Unintentional ABO mismatch kidney transplantation can cause detrimental hyperacute rejection. We report the first successful ABO incompatible kidney transplantation from an AB para-Bombay donor to O recipient. At the initial evaluation, the donor's ABO type was discordance on the cell typing and serum typing, which typed to be ‘O’ as cell typing and ‘AB’ as serum typing. At the second investigation, it was confirmed that the donor had a unique, rare but not uncommon blood type AB para-Bombay ...

    Cancer is a unique disease characterized by abnormal growth of cells which have the ability to invade the adjacent tissues and sometimes even distant organs. The limited and contrasting evidence regarding the association of ABO blood groups with the different types of head and neck cancers in the Indian population warrants the need for the present study. To assess the relative risk of various Head & Neck cancers among different blood groups. Three hundred sixty two diagnosed cases of different type of head and neck cancers and 400 controls were selected from four hospitals of New Delhi, India. The information regarding the type of head and neck cancer was obtained from the case sheets of the patients regarding their socio demographic profile, dietary history using a structured performa. The information regarding type of cancer (cases only), ABO blood group was collected. Statistical Tests: The data was analysed using the SPSS 19 version. Chi square test and odd ratios were calculated. The level of significance was fixed at 5%. The O blood group was found to be most prevalent followed by B, A and AB among the cases as well as the controls. Oral cancer patients showed maximum number in blood group O followed by B, A and AB. Significant pattern of distribution was seen among the patients of esophageal cancer, laryngeal cancer and salivary gland cancer as well (p= 0.003, p=0.000 p=0.112 respectively. The present study reveals that there is an inherited element in the susceptibility or protection against different types of head and neck cancers. Blood group A was found to be a potential risk factor for the development of oral cancers, esophageal cancers and salivary gland cancers while blood group B was found to be a potential risk factor for laryngeal cancers.

    Helicobacter pylori infect millions of people around the world. It occupies a niche in the human gastrointestinal tract characterized by high expression of a repertoire of carbohydrates. ABO and Lewis histo-blood group systems are controlled by genes coding for functional glycosyltransferases which synthesize great diversity of related fucosylated carbohydrate in different tissues, including gastrointestinal mucosa, and exocrine secretions. The structural diversity of histo-blood group carbohydrates is highly complex and depends on epistatic interactions among gene-encoding glycosyltransferases. The histo-blood group glycosyltransferases act in the glycosylation of proteins and lipids in the human gastrointestinal tract allowing the expression of a variety of potential receptors in which H. pylori can adhere. These oligosaccharide molecules are part of the gastrointestinal repertoire of carbohydrates which act as potential receptors for microorganisms, including H. pylori. This Gram-negative bacillus is one of the main causes of the gastrointestinal diseases such as chronic active gastritis, peptic ulcer, and cancer of stomach. Previous reports showed that some H. pylori strains use carbohydrates as receptors to adhere to the gastric and duodenal mucosa. Since some histo-blood group carbohydrates are highly expressed in one but not in others histo-blood group phenotypes it has pointed out that quantitative differences among them influence the susceptibility to diseases caused by H. pylori. Additionally, some experiments using animal model are helping us to understand how this bacillus explore histo-blood group carbohydrates as potential receptors, offering possibility to explore new strategies of management of infection, disease treatment, and prevention. This text highlights the importance of structural diversity of ABO and Lewis histo-blood group carbohydrates as facilitators for H. pylori infection. Copyright © 2017 Elsevier B.V.

    Full Text Available Dermatoglyphics, the study of epidermal ridges on palm, sole, and digits, is considered as most effective and reliable evidence of identification. The fingerprints were studied in 300 Nepalese of known blood groups of different ages and classified into primary patterns and then analyzed statistically. In both sexes, incidence of loops was highest in ABO blood group and Rh +ve blood types, followed by whorls and arches, while the incidence of whorls was highest followed by loops and arches in Rh −ve blood types. Loops were higher in all blood groups except “A –ve” and “B –ve” where whorls were predominant. The fingerprint pattern in Rh blood types of blood group “A” was statistically significant while in others it was insignificant. In middle and little finger, loops were higher whereas in ring finger whorls were higher in all blood groups. Whorls were higher in thumb and index finger except in blood group “O” where loops were predominant. This study concludes that distribution of primary pattern of fingerprint is not related to gender and blood group but is related to individual digits.

    Little data are available regarding the frequencies of the blood group antigens other than ABO and RhD in the Indian population. Knowledge of the antigen frequencies is important to assess risk of antibody formation and to guide the probability of finding antigen-negative donor blood, which is especially useful when blood is required for a patient who has multiple red cell alloantibodies. This study was carried out to determine the frequencies of the D, C, c, E, e, K, k, Fy(a), Fy(b), Jk(a), Jk(b), M, N, S and s antigens in over 3,000 blood donors. Samples from randomly selected blood donors from Delhi and nearby areas (both voluntary and replacement) were collected for extended antigen typing during the period January 2009 to January 2010. Antigens were typed via automated testing on the Galileo instrument using commercial antisera. A total of 3073 blood samples from donors were phenotyped. The prevalence of these antigens was found to be as follows in %: D: 93.6, C: 87, c: 58, E: 20, e: 98, K: 3.5, k: 99.97, F(a) : 87.4, Fy(b) : 57.6, Jk(a) : 81.5, Jk(b) : 67.4, M: 88.7, N: 65.4, S: 54.8 and s: 88.7. This study found the prevalence of the typed antigens among Indian blood donors to be statistically different to those in the Caucasian, Black and Chinese populations, but more similar to Caucasians than to the other racial groups.

    Blood group-related glycans determining ABO and Lewis blood groups are known to function as attachment factors for most of the norovirus (NoV) strains. To identify binding specificity of each NoV, recombinant norovirus-like particles (VLPs) and human saliva samples with different ABO, Lewis phenotypes and secretor status have been commonly applied. When binding specificities of VLPs prepared from 16 different genotypes of NoVs in GI and GII genogroups were characterized in samples of human gastric mucosa compared to human saliva based on blood group phenotypes, considerable differences were observed for several strains. Novel binding specificities determined by an ELISA using preparations from human gastric mucosa were also ascertained by immunohistochemical analyses using human jejunal mucosa, widely believed to be susceptible to NoV infection. Further, A, B and O(H) blood group substances prepared from porcine and squid tissues were found to be effective for preventing ABO blood group-specific binding of VLPs to both saliva and mucosa samples. Therefore, these blood group substances might have potential for the prevention and treatment of NoV infection. PMID:24558470

    ABO allo-immunization is the most frequent hemolytic disease of the newborn and ABO incompatibility is present in 15-25 % of pregnancies. True ABO alloimmunization occurs in approximately one out of 150 births. Intensity is generally lower than in RhD allo-immunization. We report on three cases showing that ABO allo-immunization can lead to severe hemolytic disease of the newborn with potentially threatening hyperbilirubinemia and complications. Early diagnosis and adequate care are necessary to prevent complications in ABO incompatibility. A direct antiglobulin test is the cornerstone of diagnosis and should be performed at birth on cord blood sampling in all group infants born to O mothers, especially if of African origin. Risk factor analysis and attentive clinical monitoring during the first days of life are essential. Vigilance is even more important for infants discharged before the age of 72 h. Every newborn should be assessed for the risk of developing severe hyperbilirubinemia and should be examined by a qualified healthcare professional in the first days of life. Treatment depends on the total serum bilirubin level, which may increase very rapidly in the first 48 h of life in cases of hemolytic disease of the newborn. Phototherapy and, in severe cases, exchange transfusion are used to prevent hyperbilirubinemia encephalopathy. Intravenous immunoglobulins are used to reduce exchange transfusion. Treatments of severe hemolytic disease of the newborn should be provided and performed by trained personnel in neonatal intensive care units. Copyright © 2010 Elsevier Masson SAS.

    The experience of 28 allotransplantations of ABO-incompatible kidneys was compared with the treatment results of 38 ABO-compatible renal transplantations. The transplanted kidney function, morphological changes of the transplanted kidney and the comparative analysis of actuary survival in both groups showed no significant difference. The results of the study prove the validity of the kidney transplantation from the ABO-incompatible donors.

    2015-01-01

    Full Text Available Background: The ABO blood group system is of prime significance in red cell transfusion and organ transplantation. However, ABO compatibility is not critical in allogenic hemopoietic stem cell transplantation (HSCT and approximately 40-50% of hemopoietic stem cell transplants are ABO incompatible. This incompatibility may be major, minor or bi-directional. Though there are descriptions of transfusion practice and protocols in ABO incompatible HSCT, there are considerable variations and transfusion support in these patients can be very challenging. Aims: The immunohematologic observations in two cases of bi-directional ABO incompatible HSCT have been described, and clinico-serologic correlation has been attempted. Materials and Methods: In both cases, peripheral blood stem cell harvests were obtained using the Cobe spectra cell separator. Immunohematologic assessments in the donor and recipient were done as a part of pre HSCT evaluation. Both the standard tube technique and column agglutination method (Ortho Biovue Micro Bead System was used. Antibody screen was done by column agglutination method using three cell panel (Surgiscreen cells. Isoagglutinin titration was done by the master dilution method and standard validated techniques were used. Results: The pattern of laboratory findings in the two cases was different and so were the clinical outcomes. Although there was early engraftment in the first case, the second case developed pure red cell aplasia and this was well-reflected in the immunohematologic assessments. Conclusion: Immunohematologic assessment correlated well with the clinical picture and could be used to predict clinical outcome and onset of complications in ABO incompatible HSCT.

    Ael is a rare blood type that is characterized by weak agglutination of RBCs when reacts with anti-A antibody in adsorption-elution test. Although IVS6 + 5G→A mutation is known to associate with the Ael blood type, genetic and mechanistic evaluation for the weak agglutination of Ael with IVS6 + 5G→A mutation has not yet been completely addressed. In this study, five cases of confirmed Ael individuals were analysed. The cDNAs for the A(el) alleles were obtained by cloning method for sequence analyses. The erythroleukemia K562 cells were used as the cell study model and were transfected with the A(el) expression construct. Flow cytometry analysis was then performed to determine the levels of surface antigen expression. The results indicated that IVS6 + 5G→A attributes to all cases of Ael . RT-PCR analyses revealed the presence of at least 10 types of aberrant A(el) splicing transcripts. Most of the transcripts caused early termination and produced non-functional protein during translation. Nevertheless, the transcript without exons 5-6 was predicted to generate functional Ael glycosyltransferase lacking 57 amino acids at the N-terminal segment. When the exons 5-6 deletion transcript was stably expressed in the K562 cells, weak agglutination of the cells can be induced by adding anti-A antibody followed by adsorption-elution test. This study demonstrates that aberrant splicing of A transcripts contributes to weak A expression and the weak agglutination of Ael -RBCs, adding to the complexity for the regulatory mechanisms of ABO gene expression. © 2014 International Society of Blood Transfusion.

    To study the relationship between IgG titer of pregnant women and hemolytic disease of newborn(HDN) with different blood groups. Four hundred pregnant women, including pregnant women with type O blood, were selected from May 2014 to January 2015 in our hospital for inspection and a couple of different blood groups, the IgG titer of pregnant women were detected in the inspection process. According to neonatal HDN, newborns were divided into 2 groups: HDN group(85 cases) and non-HDN group(315 cases). The incidence of postpartum neonatal hemolytic disease was tracked and the correlation of IgG titers with HDN were systematically analyzed. In the production and inspection process, the IgG titer in pregnant women was divided into groups. the comparison of HDN incidence rate in 4 groups of IgG titer >64 and IgG titer group showed that the prevalence of ABO hemolytic disease of newborn were 96.9%, 79.6%, 63, 7% and 28.8%, there was a certain correlation of pregnant women IgG titers with ABO hemolytic disease of the newborn, that is, with the increase of IgG titer, the incidence of hemolytic disease of newborns increased in certain degree (r=0.8832), the risk in 4 groups of neonatal HDN was higher than that in IgG titer 64 HDN group. There is a certain corelation between prevalence of ABO-HDN and IgG titer of pregnant women. For these pregnant women, the control of the pregnant women IgG titer has a positive clinical significance to reduce the incidence of hemolytic disease of the newborn.

    The association between ABO blood groups and ovarian reserve in infertile patients has been a point of controversy. The aim of this study was to assess the correlation of certain blood groups with ovarian reserve and response to treatment in patients undergoing infertility treatment. Retrospective medical record review. Infertility clinic in the assisted reproductive technology (ART) unit at King Faisal Specialist Hospital and Research Center, Riyadh Saudi Arabia. All patients under 40 years of age who attended the infertility clinic at a tertiary care centre in 2010 and underwent in vitro fertilization (IVF) treatment in 2010 and 2011 were divided into groups according to blood type, and clinical parameters were compared. The association between blood groups and ovarian reserve using day 3 luteinzing hormone (LH) and follicular stimulating hormone (FSH) levels, and antral follical count (AFC). In 424 patients who underwent 566 IVF cycles, age, LH, FSH and AFC were similar among the different blood groups (P=.9, .1, .5, respectively). with controlled ovarian stimulation, no difference was observed among the four groups in menopausal gonadotrophin (hMG) dose or the duration of stimulation. The number of oocytes retrieved, fertilization rate, cleavage rate, and number of embryos transferred were similar. There was no difference in the cancellation rate or pregnancy rate among the groups. There was no significant association between blood type and ovarian reserve or response during IVF treatment in our population. Anti-Mullerian hormone levels are best correlated with ovarian reserve testing. Unavailability of AMH levels. Retrospective design.

    Full Text Available The ABO blood group antigens are carbohydrate moieties expressed on human red blood cells however; these antigens can also be expressed on some other cells particularly the surface of epithelial cells and may be found in mucosal secretions. In many human populations 80% secrete ABO antigens (termed 'secretors' while 20% do not (termed 'non-secretors'. Furthermore, there are disease conditions that are associated with secretor status.To investigate correlations between secretor status and HIV infection among female sex workers in Nairobi, Kenya.This cross-sectional study recruited 280 female sex workers aged 18-65 years from the Pumwani Majengo cohort, Kenya. Blood typing was determined by serological techniques using monoclonal antibodies to the ABO blood group antigens. Secretor phenotyping was determined using anti-H specific lectins specific to salivary, vaginal and cervical blood group H antigen using the agglutination inhibition technique and correlated to individual HIV sero-status. Participants were additionally screened for Bacterial vaginosis, Neisseria gonorrhoea and Trichomonas vaginalis.Out of the 280 participants, 212 (75.7% were secretors and 68 (24.3% were non-secretors. The incidence of all infections: HIV, Bacterial vaginosis, Neisseria gonorrhoea and Trichomonas vaginalis was higher among secretors compared to non-secretors. However, this difference was only statistically significant for HIV infection incidence rates: HIV infected secretors (83.7% versus HIV un-infected secretors (71.8% (p = 0.029 Based on ABO phenotype stratification, the incidence of HIV infection was higher among blood group A secretors (26/52 = 50%, in comparison to B (12/39 = 33.3%: p = 0.066, AB (3/9 = 33.3%: p = 0.355, and O secretors (36/112 = 32.1%: p = 0.028.This is the first report to document the variable expression of the ABH blood group antigens profiling secretor and non-secretor phenotypes in the female genital tract among a high-risk population

    Background: Although the practice of preoperative testing of ABO group and Rh (D) type for elective cholecystectomy has deep historical roots, it is not evidence-based. We aimed to assess the preoperative blood group and save testing practice for a cohort of patients subjected to elective laparoscopic cholecystectomy for symptomatic cholecystolithiasis between January 2010 and October 2014. Methods: National Health Service (NHS) hospital based, surgical procedure-specific, retrospective study was conducted. A final group consisted of 2,079 adult patients. We estimated the incidence of perioperative blood transfusion attributable to laparoscopic cholecystectomy. The results of eight other studies are presented. Results: A preoperative blood group and save test was performed in 907 patients (43.6%), whereas cross-matching was documented in 28 patients (3.1%). None required an intraoperative blood transfusion. Twelve patients (0.58%) underwent blood transfusion postoperatively following laparoscopic cholecystectomy, of which ten were transfused due to severe intra-abdominal bleeding (0.48%). There were no deaths. Conclusions: The likelihood of blood transfusion attributable to elective laparoscopic cholecystectomy is 1:200. A routine preoperative blood group and save testing is unnecessary. It neither alters the management of severe hypovolemia, secondary to perioperative bleeding, nor does it lead to better outcomes.

    Background West Nile virus (WNV) infection is mostly asymptomatic but 20% of subjects report WNV fever and 1% of patients experience neurological diseases with higher rates in elderly and immunosuppressed persons. With no treatment and no vaccine to prevent the development of symptomatic infections, it is essential to understand prognostic factors influencing symptomatic disease outcome. Host genetic background has been linked to the development of WNV neuroinvasive disease. The present study investigates the association between the ABO and Rh(D) blood group status and WNV disease outcome. Study Design and Methods The distribution of blood groups was investigated within a cohort of 374 WNV+ blood donors including 244 asymptomatic (AS) and 130 symptomatic (S) WNV+ blood donors. Logistic regression analyses were used to examine associations between A, B, O and Rh(D) blood groups and WNV clinical disease outcome. Results Symptomatic WNV+ donors exhibited increased frequencies of blood group A (S 47.6% AS 36.8%, P=0.04, OR [95%CI] 1.56 [1.01–2.40]) and Rh(D)-negative individuals (S 21.5% AS 13.1%, P=0.03, OR [95%CI] 1.82 [1.04–3.18]). Conclusion The findings suggest a genetic susceptibility placing blood group A and Rh(D)-negative individuals at risk for the development of symptomatic disease outcome after WNV infection.

    ABO remains the clinically most important blood group system, but despite earlier extensive research, significant findings are still being made. The vast majority of catalogued ABO null alleles are based on the c.261delG polymorphism. Apart from c.802G>A, other mechanisms for O alleles are rare. While analysing the data set from the 1000 Genomes (1000G) project, we encountered two previously uncharacterized deletions, which needed further exploration. The Erythrogene database, complemented with bioinformatics software, was used to analyse ABO in 2504 individuals from 1000G. DNA samples from selected 1000G donors and African blood donors were examined by allele-specific PCR and Sanger sequencing to characterize predicted deletions. A 5821-bp deletion encompassing exons 5-7 was called in twenty 1000G individuals, predominantly Africans. This allele was confirmed and its exact deletion point defined by bioinformatic analyses and in vitro experiments. A PCR assay was developed, and screening of African samples revealed three donors heterozygous for this deletion, which was thereby phenotypically established as an O allele. Analysis of upstream genetic markers indicated an ancestral origin from ABO*O.01.02. We estimate this deletion as the 3rd most common mechanism behind O alleles. A 24-bp deletion was called in nine individuals and showed greater diversity regarding ethnic distribution and allelic background. It could neither be confirmed by in silico nor in vitro experiments. A previously uncharacterized ABO deletion among Africans was comprehensively mapped and a genotyping strategy devised. The false prediction of another deletion emphasizes the need for cautious interpretation of NGS data and calls for strict validation routines. © 2017 International Society of Blood Transfusion.

    ABO hemolytic disease occurs among neonates with blood groups A or B delivered to group O women. Extreme neonatal hyperbilirubinemia due to ABO disease has been reported, but its frequency is not well known. We sought to determine the odds of developing severe ABO hemolytic disease in the 13 years since adopting universal bilirubin screening/management in the Intermountain Healthcare system. We conducted a retrospective analysis of neonates born between 2004 and 2016, defining "severe hemolytic disease" as; (1) total serum bilirubin (TSB) >25 mg/dL, or (2) hospital readmission for jaundice, or (3) bilirubin encephalopathy. Neonates born to group O (+) mothers were included and considered either; (1) Controls (not at risk for ABO disease because they were group O), (2) Study subjects (at risk for ABO disease because they were group A or B). Of 400,531 live births, 47% were to group O women; 86% of whom were group O (+). Overall, 42,529 (27%) neonates born to group O (+) women had their blood group determined; 29,729 (68%) were O, 10,682 (25%) A, and 3109 (7%) B. Peak TSBs during the first 10 days were higher in group A (11.0 ± 4.2 mg/dL) and B (11.5 ± 4.3) than group O neonates (10.3 ± 4.1). However the relative risks of a TSB ≥25 mg/dL, readmission for jaundice, or kernicterus, were the same in the control vs. study groups. In our health system, severe hemolytic disease in neonates born to group O (+) woman is not more likely in group A or B neonates than in controls (group O). We recognize that in other practices, particularly those who do not have a universal bilirubin screening/management program, ABO hemolytic disease severity might be different than in our system.

    ABO incompatibility is no longer considered a contraindication for adult living donor liver transplantation (ALDLT) due to various strategies to overcome the ABO blood group barrier. We report the largest single-center experience of ABO-incompatible (ABOi) ALDLT in 235 adult patients. The desensitization protocol included a single dose of rituximab and total plasma exchange. In addition, local graft infusion therapy, cyclophosphamide, or splenectomy was used for a certain time period, but these treatments were eventually discontinued due to adverse events. There were three cases (1.3%) of in-hospital mortality. The cumulative 3-year graft and patient survival rates were 89.2% and 92.3%, respectively, and were comparable to those of the ABO-compatible group (n = 1301). Despite promising survival outcomes, 17 patients (7.2%) experienced antibody-mediated rejection that manifested as diffuse intrahepatic biliary stricture; six cases required retransplantation, and three patients died. ABOi ALDLT is a feasible method for expanding a living liver donor pool, but the efficacy of the desensitization protocol in targeting B cell immunity should be optimized. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    The purpose of this study is to examine whether postoperative antiblood type antibody rebound is attributed to kidney allograft rejection in ABO blood type-incompatible (ABO-I) living-related kidney transplantation (KTx). A total of 191 ABO-I recipients who received ABO-I living-related KTx between 2001 and 2013 were divided into two groups: Group 1 consisted of low rebound [(≦1:32), N = 170] and Group 2 consisted of high rebound [(≧1:64), N = 21], according to the levels of the rebounded antiblood type antibodies within 1 year after transplantation. No prophylactic treatment for rejection was administered for elevated antiblood type antibodies, regardless of the levels of the rebounded antibodies. Within 1 year after transplantation, T-cell-mediated rejection was observed in 13 of 170 recipients (13/170, 8%) in Group 1 and in 2 of 21 recipients (2/21, 10%) in Group 2 (Groups 1 vs. 2, P = 0.432). Antibody-mediated rejection was observed in 15 of 170 recipients (15/170, 9%) and 2 of 21 recipients (2/21, 10%) in Groups 1 and 2, respectively (P = 0.898). In this study, we found no correlation between the postoperative antiblood type antibody rebound and the incidence of acute rejection. We concluded that no treatment is necessary for rebounded antiblood type antibodies. © 2014 Steunstichting ESOT.

    Human blood groups are a significant resource for patients, leading to a fierce international competition in the screening of rare blood groups. Some rare blood group screening programs have been implemented in western countries and Japan, but not particularly in China. Recently, the genetic background of ABO and Rh blood groups for different ethnic groups or regions in China has been focused on increasingly. However, rare blood groups such as MN, Duffy, Kidd, MNS, and Diego are largely unexplored. No systematic reports exist concerning the polymorphisms and allele frequencies of rare blood groups in China's ethnic minorities such as Uygur and Kazak populations of Xinjiang, unlike those on the Han population. Therefore, this study aimed to investigate the allele frequencies of rare blood groups, namely, MNS, Duffy, Kell, Dombrock, Diego, Kidd, Scianna, Colton, and Lutheran in the Uygur population of Xinjiang Single specific primer-polymerase chain reaction was performed for genotyping and statistical analysis of 9 rare blood groups in 158 Uygur individuals. Allele frequencies were compared with distribution among other ethnic groups. Observed and expected values of genotype frequencies were compared using the chi-square test. Genotype frequencies obeyed the Hardy-Weinberg equilibrium (P > 0.5) and allele frequencies were stable. Of all subjects detected, 4 cases carried the rare phenotype S - s - of MNS blood group (frequency of 0.0253), and 1 case carried the phenotype Jk a-b- (frequency of 0.0063). Frequencies of the four groups, MNS, Duffy, Dombrock, and Diego, in the Uygur population differed from those in other ethnic groups. Gene distribution of the Kell, Kidd, and Colton was similar to that in Tibetan and Han populations, though there were some discrepancies. Gene distribution of Scianna and Lutheran groups showed monomorphism similar to that in Tibetan and Han populations. These findings could contribute to the investigation of the origin, evolution, and

    Pre-eclampsia is an important cause of maternal morbidity and mortality. Its etiology is still unknown. Clinical symptoms correlate with activation of coagulation and inherited thrombophilia has been associated with pre-eclampsia. ABO blood group has been associated with thrombotic disorders and pre-eclampsia. We assessed ABO blood group, seven thrombophilia associated polymorphisms, and anti-beta2-glycoprotein I antibodies as risk factors for pre-eclampsia. We performed a population-based nested case-control study of 100,000 consecutive pregnancies in Finland. Cases and controls were identified by combining national registers and medical records were reviewed. We studied 248 cases fulfilling strict criteria for pre-eclampsia and 679 controls. Severe pre-eclampsia, early pre-eclampsia, and pre-eclampsia with intra-uterine growth restriction (IUGR) were analyzed separately. Blood group AB increased the risk for pre-eclampsia as a whole (OR 2.1, 95% CI 1.3-3.5), and in the three subgroups (OR 2.3, 3.8, 3.4; 95% CI 1.3-3.9, 2.0-7.1, 1.6-7.1). FV Leiden increased the risk as a whole (OR 1.7, 95% CI 0.8-3.9), and in the three subgroups, although not statistically significantly. Anti-beta2-glycoprotein I antibodies were not associated with pre-eclampsia. High body mass index, diabetes, first pregnancy, and twin pregnancy increased the risk from 1.5-fold to 8.2-fold. Our results confirm and extend the prior observation of blood group AB being a risk factor for pre-eclampsia. ABO blood group is known from all pregnant women. The value of blood group as risk factor for pre-eclampsia should be further assessed in prospective studies. In this study, FV Leiden was not statistically significant risk factor.

    Human blood can be divided into groups, which is a method of blood classification based on the presence or absence of inherited erythrocyte surface antigens that can elicit immune response. According to the International Society of Blood Transfusion, there are 341 blood group antigens collected in 35 blood group systems. These antigens can be proteins, glycoproteins or glycosphingolipids, and function as transmembrane transporters, ion channels, adhesion molecules or receptors for other proteins. The majority of blood group antigens is present also on another types of cells. Due to their localization on the surface of cells, blood group antigens can act as receptors for various pathogens or their toxins, such as protozoa (malaria parasites), bacteria (Helicobacter pylori, Vibrio cholerae and Shigella dysenteriae) and viruses (Noroviruses, Parvoviruses, HIV). If the presence of group antigen (or its variant which arised due to mutation) is beneficial for the host (e.g. because pathogens are not able to bind to the cells), the blood group may become a selection trait, leading to its dissemination in the population exposed to that pathogen. There are thirteen blood group systems that can be related to pathogen resistance, and it seems that the particular influence was elicit by malaria parasites. It is generally thought that the high incidence of blood groups such as O in the Amazon region, Fy(a-b-) in Africa and Ge(-) in Papua-New Guinea is the result of selective pressure from malaria parasite. This review summarizes the data about relationship between blood groups and resistance to pathogens.

    The ABO blood types are associated with cancers, cardiovascular diseases and type 2 diabetes mellitus but whether they are also associated with gestational diabetes mellitus (GDM) is unknown. We examined the relationship between the ABO blood types and the risk of GDM in a prospective population-based Chinese cohort. From 2010 to 2012, we recruited 14,198 pregnant women within the first 12 weeks of gestation in Tianjin, China. All women had a glucose challenge test (GCT) at 24-28 gestational weeks, followed by a 75-g 2-h oral glucose tolerance test if the results from GCT were ≥7.8 mmol/L. GDM was diagnosed based on the glucose cut-points of the International Association of Diabetes and Pregnancy Study Group criteria. Logistic regression was used to obtain odds ratios (ORs) and 95% confidence intervals (CIs) adjusted for traditional risk factors. Stratified analysis was performed by family history of diabetes (yes versus no). Sensitivity analyses were also performed by using the World Health Organization (WHO) criteria for GDM. Women with blood groups A, B or O (i.e. non-AB) were associated with increased risk of GDM as compared with those with blood group AB (adjusted OR: 1.44, 95% CI: 1.13-1.83). Sensitivity analyses showed that the result was consistent using WHO criteria. The adjusted OR of blood group non-AB versus AB for GDM was enhanced among women with a family history of diabetes (2.69, 1.21-5.96) and attenuated among those without (1.33, 1.03-1.71). Blood group AB was a protective factor against GDM in pregnant Chinese women. Copyright © 2015 John Wiley & Sons, Ltd.

    Detection of blood group is an essential factor in critical conditions before performing blood transfer. At presently tests are conducted by lab technicians manually in the laboratory. When the test is done by technicians with large samples it becomes monotonous to do and sometimes it leads to incorrect results and even its time consuming to get the result. The research survey proposal is to reduce the physical work to identify the blood group with a paper-based device. The paper is having a long thermometer with two ends. By using this we can detect the blood type by changing the color of the paper. Chemical reactions between dye, Bromo creosol green, and blood serum proteins, were performed to test the blood sample. The paper becomes teal or brown color, depending on whether the association of antibodies and antigens are present. It gives the result within 30 seconds, which is quicker than traditional detection system. The tested blood sample had a good accuracy rate.

    OBJECTIVE OF THE STUDY. To evaluate the correlation between total serum bilirubin (TSB) and transcutaneous bilirubin (TcB) levels in newborn infants at risk of ABO hemolytic disease. MATERIAL AND METHODS. During a prospective study, 130 full-term (>or=37 weeks of gestation) newborn infants with diagnosed ABO blood group incompatibility were examined. TSB level was measured at the age of 6 hours; further measurements were performed at 24, 48, and 72 hours following the first measurement. Blood samples were collected from the peripheral veins. In clinical laboratory, total serum bilirubin level was measured using Jendrassik-Grof method. TcB level in the forehead was measured using a noninvasive bilirubinometer BiliCheck (SpectRX Inc, Norcross, GA) according to the manufacturer's instructions within +/-30 min after getting a blood sample. RESULTS. During the study, 387 double tests were performed to measure TSB and TcB levels. TSB level (114.83 [62.85] micromol/L) closely correlated with TcB level (111.51 [61.31] micromol/L) (r=0.92, Por=98 micromol/L, ABO hemolytic disease in newborns may be diagnosed with 100% sensitivity and 98% specificity; positive predictive value was 62% and negative predictive value was 100%. While a newborn's age increases, TcB sensitivity and specificity for diagnosing ABO hemolytic disease decrease. CONCLUSION. While evaluating bilirubin level transcutaneously according to nomograms of serum bilirubin level, the results should be considered with caution, especially for newborns with a risk of ABO hemolytic disease. The hour-specific nomograms of transcutaneous bilirubin level should be used to evaluate hyperbilirubinemia using only a noninvasive method.

    A positive crossmatch indicates the presence of donor-specific alloantibodies and is associated with a graft loss rate of >80%; anti-ABO blood group antibodies develop in response to exposure to foreign blood groups, resulting in immediate graft loss. However, a desensitization protocol for highly HLA-sensitized and ABO-incompatible high-titer kidney transplantation has not yet been established. We treated 6 patients with high (≥1:512) anti-A/B antibody titers and 2 highly HLA-sensitized patients. Our immunosuppression protocol was initiated 1 month before surgery and included mycophenolate mofetil (1 g/d) and/or low-dose steroid (methylprednisolone 8 mg/d). Two doses of the anti-CD20 antibody rituximab (150 mg/m(2)) were administered 2 weeks before and on the day of transplantation. We performed antibody removal with 6-12 sessions of plasmapheresis (plasma exchange or double-filtration plasmapheresis) before transplantation. Splenectomy was also performed on the day of transplantation. Postoperative immunosuppression followed the same regimen as ABO-compatible cases, in which calcineurin inhibitors were initiated 3 days before transplantation, combined with 2 doses of basiliximab. Of the 8 patients, 7 subsequently underwent successful living-donor kidney transplantation. Follow-up of our recipients showed that the patient and graft survival rates were 100%. Acute cellular rejection and antibody-mediated rejection episodes occurred in 1 of the 7 recipients. These findings suggest that our immunosuppression regimen consisting of rituximab infusions, splenectomy, plasmapheresis, and pharmacologic immunosuppression may prove to be effective as a desensitization protocol for highly HLA-sensitized and ABO-incompatible high-titer kidney transplantation.

    Full Text Available Background: Currently, there is a constant need to find microbial products for maintaining or even improving host microbiota balance that could be targeted to a selected consumer group. Blood group secretor status, determining the ABO status, could be used to stratify the consumer group. Objective: We have applied a validated upper intestinal tract model (TIM-1 and culturing methods to screen potential probiotic bacteria from faeces of blood secretor and non-secretor individuals. Design: Faecal samples from healthy volunteers were pooled to age- and sex-matched secretor and non-secretor pools. Faecal pools were run through separate TIM-1 simulations, and bacteria were cultivated from samples taken at different stages of simulations for characterisation. Results: Microbes in secretor pool survived the transit through TIM-1 system better than microbes of non-secretor pool, especially bifidobacteria and anaerobes were highly affected. The differences in numbers of bifidobacteria and lactobacilli isolates after plate cultivations and further the number of distinct RAPD-genotypes was clearly lower in non-secretor pool than in secretor pool. Conclusions: In the present study, we showed that microbiota of secretor and non-secretor individuals tolerate gastrointestinal conditions differently and that a combination of gastrointestinal simulations and cultivation methods proved to be a promising tool for isolating potentially probiotic bacteria.

    Alloimmunization to red blood cell antigens is seen in patients receiving chronic blood transfusion. Knowing the prevalence of blood group antigens of the different ethnicities of South Texas donors can provide better management of rare blood inventory for patients in this geographical area. A total of 4369 blood donors were tested and analyzed for various antigens in the following blood group systems: ABO, Rh, Kell, Duffy, Kidd, MNS, Lutheran, Dombrock, Landsteiner-Wiener, Diego, Colton, and Scianna. Donors tested to be group 0 or A were serologically tested for the Rh (C, E, c, e) antigens. Those that tested as presumably R1R1, R2R2, or Ror were then genotyped. Donors constituted three major ethnicities: black (18.3%), Hispanic (36.3%), and Caucasian (41.1%); ethnicities comprised of Asian, American Indian, multiracial, and other accounted for the remaining donors (4.3%). The most likely common Rh phenotype for each ethnicity is as follows: black -Ror (44.4%), Hispanic -R1R1 (59.0%), and Caucasian -R1R1 (38.9%). The prevalence of Kell, Duffy, and Kidd blood group system antigens in black and Caucasian donors is comparable with published reports for the entire U.S. The black South Texas donor population had an 8.8 percent increase in prevalence of the Fy(a+b-) phenotype as compared with these published reports; the Hispanic South Texas donor population had a prevalence of 36.1 percent of the Fy(a+b-) phenotype. Regarding the Diego blood group system, the Hispanic donor population in South Texas had a prevalence of 93.5 percent for the Di(a-b+) phenotype as compared with published reports for the entire U.S. (>99.9%). The Hispanic population had a prevalence of 7.9 percent of donors testing as M-N+S-s+ as compared with 20.2 percent and 15.6 percent for black and Caucasian donors, respectively. This study helped us determine the prevalence of each of the blood group antigens in the South Texas donor population to establish and maintain adequate rare inventory of

    Plasmodium vivax has been reported to cause severe malaria, and one of the main resulting complications is anemia. Considering that P. vivax infects only young erythrocytes, anemia has been associated with the destruction of infected and non-infected erythrocytes. However, few studies have focused on understanding the relationship between the pathogenesis of P. vivax malaria and human genetic polymorphisms. Although ABO groups seem to influence the outcome of Plasmodium falciparum malaria, the association between P. vivax and ABO blood groups has been minimally investigated. Thus, we investigate the correlation between ABO blood groups and anemia induced by P. vivax infection. Five single nucleotide polymorphisms at the ABO gene were genotyped by PCR-RFLP and Real-Time PCR in P. vivax-infected subjects. The ABO blood types were associated with the hematological data of the patients. Our main finding was that type O infected-individuals showed lower levels of hemoglobin and hematocrit compared to type A-infected individuals. The correlation between ABO blood groups and hemoglobin levels remained significant when a multiple linear regression was applied with the possible confounding effects of clinical-epidemiologic variables taken into account. The finding that type O individuals have a higher frequency of anemia is a first step to understand the mechanisms involved in malaria anemia, which could be associated to increased destruction of type O erythrocytes.

    Recent investigation of transcriptional regulation of the ABO genes has identified a candidate erythroid cell-specific regulatory element, named the +5·8-kb site, in the first intron of ABO. Six haplotypes of the site have been reported previously. The present genetic population study demonstrated that each haplotype was mostly linked with specific ABO alleles with a few exceptions, possibly as a result of hybrid formation between common ABO alleles. Thus, investigation of these haplotypes could provide a clue to further elucidation of ABO alleles. © 2015 International Society of Blood Transfusion.

  13. Role of ABO secretor status in mucosal innate immunity and H. pylori infection.

    2008-01-01

    Full Text Available The fucosylated ABH antigens, which constitute the molecular basis for the ABO blood group system, are also expressed in salivary secretions and gastrointestinal epithelia in individuals of positive secretor status; however, the biological function of the ABO blood group system is unknown. Gastric mucosa biopsies of 41 Rhesus monkeys originating from Southern Asia were analyzed by immunohistochemistry. A majority of these animals were found to be of blood group B and weak-secretor phenotype (i.e., expressing both Lewis a and Lewis b antigens, which are also common in South Asian human populations. A selected group of ten monkeys was inoculated with Helicobacter pylori and studied for changes in gastric mucosal glycosylation during a 10-month period. We observed a loss in mucosal fucosylation and concurrent induction and time-dependent dynamics in gastric mucosal sialylation (carbohydrate marker of inflammation, which affect H. pylori adhesion targets and thus modulate host-bacterial interactions. Of particular relevance, gastric mucosal density of H. pylori, gastritis, and sialylation were all higher in secretor individuals compared to weak-secretors, the latter being apparently "protected." These results demonstrate that the secretor status plays an intrinsic role in resistance to H. pylori infection and suggest that the fucosylated secretor ABH antigens constitute interactive members of the human and primate mucosal innate immune system.

    Serum lipase activities above the threefold upper reference limit indicate acute pancreatitis. We investigated whether high lipase activity-within the reference range and in the absence of pancreatitis-are associated with genetic single nucleotide polymorphisms (SNP), and whether these identified SNPs are also associated with clinical pancreatitis. Genome-wide association studies (GWAS) on phenotypes 'serum lipase activity' and 'high serum lipase activity' were conducted including 3966 German volunteers from the population-based Study-of-Health-in-Pomerania (SHIP). Lead SNPs associated on a genome-wide significance level were replicated in two cohorts, 1444 blood donors and 1042 pancreatitis patients. Initial discovery GWAS detected SNPs within or near genes encoding the ABO blood group specifying transferases A/B (ABO), Fucosyltransferase-2 (FUT2), and Chymotrypsinogen-B2 (CTRB2), to be significantly associated with lipase activity levels in asymptomatic subjects. Replication analyses in blood donors confirmed the association of FUT-2 non-secretor status (OR=1.49; p=0.012) and ABO blood-type-B (OR=2.48; p=7.29×10(-8)) with high lipase activity levels. In pancreatitis patients, significant associations were found for FUT-2 non-secretor status (OR=1.53; p=8.56×10(-4)) and ABO-B (OR=1.69, p=1.0×10(-4)) with chronic pancreatitis, but not with acute pancreatitis. Conversely, carriers of blood group O were less frequently affected by chronic pancreatitis (OR=0.62; p=1.22×10(-05)) and less likely to have high lipase activity levels (OR=0.59; p=8.14×10(-05)). These are the first results indicating that ABO blood type-B as well as FUT2 non-secretor status are common population-wide risk factors for developing chronic pancreatitis. They also imply that, even within the reference range, elevated lipase activities may indicate subclinical pancreatic injury in asymptomatic subjects. Published by the BMJ Publishing Group Limited.

    An understanding of the ABO and Rh blood group systems is important for blood transfusions and is also pertinent due to their potential association with certain morbidities and susceptibilities to infections. To investigate the diversity and differentiation of the ABO and Rh loci in Middle Eastern populations, data from twelve representative Middle Eastern populations were analyzed. Six populations were in conformity with Hardy-Weinberg equilibrium at the ABO locus. The pooled heterozygosity at both loci was calculated to be highest in the sample from Jordan and lowest in Bahrain. Heterogeneity was pronounced in the Northern compared to the Southern Middle Eastern populations. Overall, the absolute gene diversity was 0.0046 and gene differentiation was calculated to be 0.0100. Genetic diversity of the studied loci across all populations (HT) was estimated to be 0.4594, while the diversity within the populations (HS) was 0.4548. Nei's genetic distance analyses revealed highest affinities between the populations of Kuwait and Qatar, Oman and Yemen, and between Qatar and the United Arab Emirates. These results were displayed through a UGPMA dendrogram and principal component analyses, which established clustering of certain populations. Clinal trends of the allelic systems were observed by generating contour maps that allow a detailed appreciation of the distributions of alleles across the geography of the Arabian Peninsula and the Middle East. Taken together, these analyses are helpful in understanding the differentiation of blood group loci and for designing prospective studies for establishing the associations of these loci with health variables in the populations studied.

    Full Text Available Abstract Background Recently, genome-wide association studies identified a pleiotropic gene locus, ABO, as being significantly associated with hematological traits. To confirm the effects of ABO on hematological traits, we examined the link between the ABO locus and hematological traits in Korean population-based cohorts. Results Six tagging SNPs for ABO were analyzed with regard to their effects on hematological traits [white blood cell count (WBC, red blood cell count (RBC, platelet (Plat, mean corpuscular volume (MCV, and mean corpuscular haemoglobin concentration (MCHC]. Linear regression analyses were performed, controlling for recruitment center, sex, and age as covariates. Of the 6 tagging SNPs, 3 (rs2073823, rs8176720, and rs495828 and 3 (rs2073823, rs8176717, and rs687289 were significantly associated with RBC and MCV, respectively (Bonferroni correction p-value criteria r2s = 0.99. Of the remaining 3 SNPs (rs8176720, rs8176717 and rs687289, rs8176717 generated an independent signal with moderate p-value (= 0.045 when it was adjusted for by rs2073823 (the most significant SNP. We also identified a copy number variation (CNV that was tagged by the SNP rs8176717, the minor allele of which correlated with the deletion allele of CNV. Our haplotype analysis indicated that the haplotype that contained the CNV deletion was significantly associated with MCV (β ± se = 0.363 ± 0.118, p =2.09 × 10-3. Conclusions Our findings confirm that ABO is one of the genetic factors that are associated with hematological traits in the Korean population. This result is notable, because GWASs fail to evaluate the link between a CNV and phenotype traits.

    With the ever-changing field of criminal justice, the constant revision of criteria for acceptable evidence by the judiciary poses new challenges in forensic investigation. The applicability of cheiloscopy in individual identification is an area of extensive research in recent years. The aim of the present study was to determine the distribution of different lip print patterns in North Kerala population, to assess any sexual dimorphism in lip patterns, and to correlate lip print patterns with ABO and Rh blood groups. A total of 858 students, 471 males and 387 females, from different colleges in the district of Kozhikode in North Kerala were included in the study. Lip prints were obtained using lipstick and cello tape and transferred onto white papers. Blood group of the participants was noted. The most predominant pattern observed was Type I (48.3%), followed by Type II, Type III, Type IV, Type I', and Type V. We also observed that the lower lip exhibited an overwhelming predominance of Type I pattern in the North Kerala population while the upper lip showed a more even distribution. Gender-wise difference was observed with Type II being the most common in males and Type IV being the predominant pattern in females. No correlation was obtained between the blood groups and lip patterns. The potential usefulness of cheiloscopy in forensic medicine still remains largely untapped and under-recognized. Similar studies in different populations with large sample sizes will allow a more definite picture of lip print patterns to emerge.

    To evaluate whether the use of intravenous immunoglobulin in newborn infants with isoimmune hemolytic jaundice due to Rh and ABO incompatibility is an effective treatment in reducing the need for exchange transfusion. This study included all direct Coombs' test positive Rh and ABO isoimmunized babies, who admitted in the Neonatal Intensive Care Unit of Ghaem Hospital of Mashhad University of Medical Sciences, Iran, from October 2003 to October 2004. Significant hyperbilirubinemia was defined as rising by >or=0.5 mg/dl per hour. Babies were randomly assigned to received phototherapy with intravenous immunoglobulin (IVIg) 0.5 g/kg over 4 hours, every 12 hours for 3 doses (study group) or phototherapy alone (control group). Exchange transfusion was performed in any group if serum bilirubin exceeded >or=20mg/dl or rose by >or=1mg/dl/h. A total of 34 babies were eligible for this study (17 babies in each group). The number of exchange transfusion, duration of phototherapy and hospitalization days, were significant shorter in the study group versus control group. When we analyzed the outcome results in ABO and Rh hemolytic disease separately, the efficacy of IVIg was significantly better in Rh versus ABO isoimmunization. Late anemia was more common in the IVIg group 11.8% versus 0%, p=0.48. Adverse effects were not observed during IVIg administration. Administration of IVIg to newborns with significant hyperbilirubinemia due to Rh hemolytic disease reduced the need for exchange transfusion but in ABO hemolytic disease there was no significant difference between IVIg and double surface blue light phototherapy.

    This study describes patient identification errors leading to transfusional near-misses in blood issued by the Alps Mediterranean French Blood Establishment (EFSAM) to Marseille Public Hospitals (APHM) over an 18-month period. The EFSAM consolidates 14 blood banks in southeast France. It supplies 149 hospitals and maintains a centralized database on ABO types used at all area hospitals. As an added precaution against incompatible transfusion, the APHM requires ABO testing at each admission regardless of whether the patient has an ABO record. The study goal was to determine if admission testing was warranted. Discrepancies between ABO type determined by admission testing and records in the centralized database were investigated. The root cause for each discrepancy was classified as specimen collection or patient admission error. Causes of patient admission events were further subclassified as namesake (name similarity) or impersonation (identity fraud). The incidence of ABO discrepancies was 1:2334 including a 1:3329 incidence of patient admission events. Impersonation was the main cause of identity events accounting for 90.3% of cases. The APHM's ABO control policy prevented 19 incompatible transfusions. In relation to the 48,593 packed red cell units transfused, this would have corresponded to a risk of 1:2526. Collecting and storing ABO typing results in a centralized database is an essential public health tool. It allows crosschecking of current test results with past records and avoids redundant testing. However, as patient identification remains unreliable, ABO typing at each admission is still warranted to prevent transfusion errors. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    One- and two-stage radioligand assays were used to determine if human platelets possess the Lea antigen. Goat IgG anti-Lea antibody was purified by multiple adsorptions with Le(a-b-) human red blood cells, followed by affinity chromatography with synthetic Lea substance and labeling with 125 I. Human IgG anti-Lea antibody was used either in a two stage radioassay with 125 I-labeled mouse monoclonal IgG anti-human IgG as the second antibody or, alternatively, purified by Staph protein A chromatography, labeled with 125 I, and used in a one-stage radioassay. Platelets from donors of appropriate red blood cell phenotypes were incubated with the antisera, centrifuged through phthalate esters, and assayed in a gamma scintillation counter. Dose response and saturation curve analysis demonstrate the presence of Lewis a antigen on platelets from Lea+ donors. Furthermore, platelets from an Le(a-b-) donor incubated in Le (a+b-) plasma adsorb Lea antigen in a similar manner to red blood cells. The clinical significance of these antigens in platelet transfusion remains undefined

    ABO-incompatible (ABOi) hematopoietic stem cell transplants (HSCTs) can present challenges in the blood bank. During transplantation, patients receive components that are ABO-compatible with both the donor graft and recipient; this practice can strain group O red blood cell (RBC) inventories.1 In addition, there are risks for acute hemolysis at the time of infusion and in the early post-transplant period.1,2 In ABO major-incompatible bone marrow HSCTs, which contain significant quantities of donor RBCs that are ABOi with recipient plasma, it is common to perform a RBC depletion of the bone marrow in an effort to minimize hemolysis at the time of infusion.2 Furthermore, patients with high-titer ABO antibodies may undergo a prophylactic, pre-transplant plasma exchange to further reduce the risk of acute hemolysis, delayed RBC engraftment, and pure RBC aplasia.2-4 ABO minor-incompatible HSCTs, in which donor plasma is ABOi with the recipient, have less risk for hemolysis at the time of infusion but can result in transient hemolysis approximately 10-21 days post-transplant, especially in patients undergoing nonmyeloablative HSCT and/or patients who have not received methotrexate for graft-versus-host-disease (GVHD) prophylaxis.1-4 In these patients, viable donor B-lymphocytes in the graft may expand and produce ABO antibodies capable of hemolyzing patient RBCs.

    More than ten new types of gangliosides, in addition to haematoside and sialosylparagloboside, were isolated from human erythrocyte membranes. These were separated by successive chromatographies on DAEA-Sephadex, on porous silica-gel columns and on thin-layer silica gel as acetylated compounds. Highly potent blood-group-Ii and moderate blood-group-H activities were demonstrated in some of the ganglioside fractions. The gangliosides incorporated into chlolesterol/phosphatidylcholine liposomes stoicheiometrically inhibited binding of anti-(blood-group-I and i) antibodies to a radioiodinated blood-group-Ii-active glycoprotein. The fraction with the highest blood-group-I activity, I(g) fraction, behaved like sialosyl-deca- to dodeca-glycosylceramides on t.l.c. Certain blood-group-I and most of the i-determinants were in partially or completely cryptic form and could be unmasked by sialidase treatment. Thus the I and i antigens, which are known to occur on internal structures of blood-group-ABH-active glycoproteins in secretions, also occur in the interior of the carbohydrate chains of erythrocyte gangliosides.

    Red cell alloimmunization is an acknowledged complication of blood transfusion. Current transfusion practices for thalassemia do not cater to this risk. Serological phenotyping is usually not reliable in these cases unless performed before the first transfusion. Under such circumstances, molecular blood grouping is an effective alternative. To perform molecular blood group genotyping in chronically transfused thalassemia patients and assess the risk of antigenic exposure and incidence of alloimmunization with current transfusion protocols. Molecular blood group genotyping was performed for 47 chronically transfused thalassemia patients. Their 1-year transfusion records were retrieved to assess the antigenic exposure and the frequency thereof. Of 47 patients, 6 were already alloimmunized (3 with anti-E and 3 with anti-K) and were receiving the corresponding antigen negative units. We observed that random selection of ABO and Rh D matched units resulted in 57.7% ±8.26% chance of Rh and Kell phenotype matching also. Forty-four patients had received one or more antigenic exposures at least once. The 6 already alloimmunized patients were further exposed to antigens other than the ones they were immunized to. During the study period, only one patient developed an alloantibody, anti-E with exposure to antigens C (92%) and/or E (32%) at each transfusion. Several factors apart from mere antigen exposure may influence the development of alloimmunization as most of our patients received antigenic exposures but not alloimmunized. Our data provide an impetus for future large-scale studies to understand the development of alloimmunization in such patients.

    ABO genotyping has common tools for personal identification of forensic and transplantation field. We developed a new method based on a droplet allele-specific PCR (droplet-AS-PCR) that enabled rapid PCR amplification. We attempted rapid ABO genotyping using crude DNA isolated from dried blood and buccal cells. We designed allele-specific primers for three SNPs (at nucleotides 261, 526, and 803) in exons 6 and 7 of the ABO gene. We pretreated dried blood and buccal cells with proteinase K, and obtained crude DNAs without DNA purification. Droplet-AS-PCR allowed specific amplification of the SNPs at the three loci using crude DNA, with results similar to those for DNA extracted from fresh peripheral blood. The sensitivity of the methods was 5%-10%. The genotyping of extracted DNA and crude DNA were completed within 8 and 9 minutes, respectively. The genotypes determined by the droplet-AS-PCR method were always consistent with those obtained by direct sequencing. The droplet-AS-PCR method enabled rapid and specific amplification of three SNPs of the ABO gene from crude DNA treated with proteinase K. ABO genotyping by the droplet-AS-PCR has the potential to be applied to various fields including a forensic medicine and transplantation medical care. © 2017 Wiley Periodicals, Inc.

    Acute aortic type III dissection is one of the most catastrophic events, with in-hospital mortality ranging between 10% and 12%. The majority of patients are treated medically, but complicated dissections, which represent 15% to 20% of cases, require surgical or thoracic endovascular aortic repair (TEVAR). For the best outcomes adequate blood transfusion support is required. Interest in the relationship between blood type and vascular disease has been established. The aim of our study is to evaluate distribution of blood groups among patients with acute aortic type III dissection and to identify any kind of relationship between blood type and patient's survival. From January 2005 to December 2014, 115 patients with acute aortic type III dissection were enrolled at the Clinic of Vascular and Endovascular Surgery in Belgrade, Serbia and retrospectively analyzed. Patients were separated into two groups. The examination group consisted of patients with a lethal outcome, and the control group consisted of patients who survived. The analysis of the blood groups and RhD typing between groups did not reveal a statistically significant difference ( p = 0.220). Our results indicated no difference between different blood groups and RhD typing with respect to in-hospital mortality of patients with acute aortic dissection type III.

As everolimus (EVR is effective for preventing calcineurin inhibitor (CNI nephrotoxicity without increasing the risk of chronic rejection and viral infection, we aimed to assess the efficacy of EVR in ABOi KT.Patients and methods: We retrospectively studied 22 patients who underwent KT and received EVR. Patients in the ABOi KT group (n=7 were compared with those in the ABO-compatible kidney transplantation group (ABOc KT; n=15. We recorded the frequency of CNI nephrotoxicity, chronic rejection, and viral infection in the 2 groups.Results: CNI nephrotoxicity, chronic rejection, and viral infection occurred in the ABOi KT and ANOc KT groups at rates of 28.3% (2/7 patients and 13.3% (2/15 patients (P=0.388, 28.3% (2/7 patients and 26.7% (4/15 patients (P=0.926, and 14.3% (1/7 patients and 26.7% (4/15 patients (P=0.517, respectively.Conclusion: Administration of EVR is effective in preventing CNI nephrotoxicity after KT. The rate of CNI nephrotoxicity was lower in the ABOc KT group than in the ABOi KT group. The rate of chronic rejection and viral infection was comparable between the groups. This study was conducted in a small cohort of patients. Hence, further evaluation with large sample sizes is necessary in the future to confirm the outcomes.

    The hypothesis that the Rh and ABO blood systems behave like the HLA system in relation to mother-conception tolerance-rejection mechanisms was tested in 25,501 mother-infant pairs. According to this hypothesis, heterozygotes carrying a paternal gene that is not present in their mothers should be better tolerated than homozygotes. Significantly more BO infants born to AO mothers. AO infants born to BO mothers, Rh(+) heterozygotes born to Rh(-) mothers, and less significantly AO infants born to OO mothers confirm the hypothesis. Fewer homozygotes occurred in Rh(-) infants born to Rh(+) mothers and in O infants born to non-O mothers. Deviations from the Hardy-Weinberg equilibrium found in the ABO system were modified by the Rh and sex of the infant. These data strongly support the hypothesis that at least two feto-maternal systems influence the destiny of pregnancies: the classical known incompatibility system which operates late in pregnancy and a new one which is based on the induction of maternal tolerance early in pregnancy: maternal tolerance seems to be better elicited by heterozygous eggs or embryos carrying a gene not present in the mother. The data also support the hypothesis that the sex ratio is influenced by feto-maternal tolerance-rejection mechanisms associated with the ABO and Rh systems.

    Intravenous Immunoglobulin G (IVIG) therapy has been used as a component of the treatment of hemolytic disease of the newborn. There is still no consensus on its use in ABO hemolytic disease of the newborn routinely. The aim of this study is to determine whether administration of IVIG to newborns with ABO incompatibility is necessary. One hundred and seventeen patients with ABO hemolytic disease and positive Coombs test were enrolled into the study. The subjects were healthy except jaundice. Infants were divided into two groups: Group I (n = 71) received one dose of IVIG (1 g/kg) and LED phototherapy whereas Group II (n = 46) received only LED phototherapy. One patient received erythrocyte transfusion in Group I, no exchange transfusion was performed in both groups. Mean duration of phototherapy was 3.1 ± 1.3 days in Group I and 2.27 ± 0.7 days in Group II (p hemolytic disease. Meticulus follow-up of infants with ABO hemolytic disease and LED phototherapy decreases morbidity. IVIG failed to show preventing hemolysis in ABO hemolytic disease.

    The study of erythrocyte antigens continues to be an intense field of research, particularly after the development of molecular testing methods. More than 300 specificities have been described by the International Society for Blood Transfusion as belonging to 33 blood group systems. The polymerase chain reaction (PCR) is a central tool for red blood cells (RBC) genotyping. PCR and agarose gel electrophoresis are low cost, easy, and versatile in vitro methods for amplifying defined target DNA (RBC polymorphic region). Multiplex-PCR, AS-PCR (Specific Allele Polymerase Chain Reaction), and RFLP-PCR (Restriction Fragment Length Polymorphism-Polymerase Chain Reaction) techniques are usually to identify RBC polymorphisms. Furthermore, it is an easy methodology to implement. This chapter describes the PCR methodology and agarose gel electrophoresis to identify the polymorphisms of the Kell, Duffy, Kidd, and MNS blood group systems.

    Use of universally ABO-compatible group AB plasma for trauma resuscitation can be challenging due to supply limitations. Many centers are now using group A plasma during the initial resuscitation of traumatically injured patients. This study was undertaken to evaluate the impact of this practice on mortality and hospital length of stay (LOS). Seventeen trauma centers using group A plasma in trauma patients of unknown ABO group participated in this study. Eligible patients were group A, B, and AB trauma patients who received at least 1 unit of group A plasma. Data collected included patient sex, age, mechanism of injury, Trauma Injury Severity Score (TRISS) probability of survival, and number of blood products transfused. The main outcome of this study was in-hospital mortality differences between group B and AB patients compared to group A patients. Data on early mortality (≤24 hr) and hospital LOS were also collected. There were 354 B and AB patients and 809 A patients. The two study groups were comparable in terms of age, sex, TRISS probability of survival, and total number of blood products transfused. The use of group A plasma during the initial resuscitation of traumatically injured patients of unknown ABO group was not associated with increased in-hospital mortality, early mortality, or hospital LOS for group B and AB patients compared to group A patients. These results support the practice of issuing thawed group A plasma for the initial resuscitation of trauma patients of unknown ABO group. © 2017 AABB.

    We evaluated the clinical relevance and pathogenic significance of anti-salivary duct autoantibodies (ASDA) in Sjögren's syndrome (SS) and rheumatoid arthritis (RA) by examining (1) their frequency in healthy controls, patients with sicca symptoms, and patients with various autoimmune and infective disorders; (2) their localization by confocal microscopy; and (3) their tissue distribution and cross reactivity with blood group antigens. Indirect immunofluorescence (IF) was performed on commercial cryostat sections of monkey parotid salivary gland. Sections were examined by fluorescence and confocal laser scanning microscopy. Sera giving positive staining on the ducts were tested by IF on a range of monkey tissues and salivary glands from several mammalian species. Blocking experiments were performed with human erythrocytes of different ABO blood groups and AB antigens. We identified 2 distinct ductal staining patterns. The first resembled ASDA described in earlier studies and showed patchy bright staining of the apical (luminal) surfaces of the ducts and staining of apical cytoplasmic vesicles. The other was only observed with anti-mitochondrial antibody positive sera and stained the mitochondrial-rich ductal epithelium in a distinctive punctate pattern. Antibodies staining the apical surface of ducts were detected rarely in patients with antiRo/La autoantibody-positive primary SS (1/76) and RA (1/36) and were found in only 1115 with RA and secondary SS. ASDA were detected in sera from 13/51 (25.5%) of patients referred to our clinic with limited sicca symptoms who were anti-Ro/La antibody-negative and had no typical clinical or laboratory features of classical primary SS. The apical ductal staining pattern was not observed with sera from 63 healthy controls without sicca symptoms or in patients with autoimmune and infective disorders. Twelve of the 13 patients whose sera gave ASDA-like staining were blood group O and one group A. Ductal staining was abolished in

    Although intravenous immunoglobulin G (IVIG) therapy has been reported in hyperbilirubinemia of Rh hemolytic disease, its use in ABO hemolytic disease has been reported in only a few studies. In our institute we have observed that almost 30% of babies with hyperbilirubinemia due to ABO hemolytic disease required exchange transfusion. To determine whether administration of IVIG to newborns with significant hyperbilirubinemia due to ABO hemolytic disease would reduce the need for exchange transfusion as a primary goal in these babies. This was a prospective study involving all newborns with significant hyperbilirubinemia due to direct Coombs-positive ABO hemolytic disease. All healthy term babies with ABO hemolytic disease with positive direct Coombs test in the period between 2000 and 2002 were identified. Significant hyperbilirubinemia was defined as hyperbilirubinemia requiring phototherapy and/or rising by 8.5 micromol/l per h (0.5 mg/dl per h) or more to require exchange transfusion. Babies were randomly assigned into two groups: group 1 (study group) received phototherapy plus IVIG (500 mg/kg); and group 2 (control group) received phototherapy alone. Exchange transfusion was carried out in any group if at any time the bilirubin level reached 340 micromol/l (20 mg/dl) or more, or rose by 8.5 micromol/l per h (0.5 mg/dl per h) in group 2. A total of 112 babies were enrolled over 2 years, 56 in each group. Exchange transfusion was carried out in four babies in the study group, while 16 babies in the control group required exchange. Late anemia was not of concern in either group. No adverse effects related to IVIG administration were recorded. Administration of IVIG to newborns with significant hyperbilirubinemia due to ABO hemolytic disease with positive direct Coomb's test reduces the need for exchange transfusion without producing immediate adverse effects.

    Acute humoral rejection is the most important risk factor for early graft loss in ABO-incompatible (ABO-i) renal transplantation (RTx) and is present from the early period after RTx. However, the characteristics of early humoral-mediated graft injury are pathologically uncertain. To analyze tissue from 10 protocol graft biopsies performed in 10 patients within 30 days post-RTx to clarify the pathologic features of early humoral-mediated graft injuries in ABO-i RTx. Pathologic findings were examined using light and electron microscopy and immunofluorescence studies for C4d. Protocol biopsies were performed within 30 days after RTx in the absence of an episode of dysfunction (creatinine concentration 1.21-1.81 mg/dL). The immunofluorescence study demonstrated C4d deposition in peritubular and glomerular capillaries. Acute glomerulitis with infiltration of mononuclear cells and neutrophils was observed in 3 patients. Furthermore, glomerulitis was accompanied by endothelial cell injuries, widening of subendothelial spaces with a double-contoured glomerular basement membrane, and mesangiolysis. In ABO-i RTx, early humoral-mediated graft injuries were observed in approximately 30% of patients despite normal graft function. They were characterized by C4d deposition and glomerular capillary injury. These findings suggest that renal glomeruli are the first site of graft injury by anti-A or anti-B blood type antibody with complement activation in ABO-i RTx.

    Anti A1 antibody in the serum of A2 and A2B individuals is rare but when present can have laboratory and clinical significance. Routine subgrouping of all A and AB blood groups in blood centres in India is difficult due to economic constraints and has always been a point of debate. This study thus brings out the prevalence of anti A1 antibody and the clinical significance related to its presence. The results of the study showed a low prevalence of anti A1 antibody and when present, it had a low thermal amplitude and titre. Further, no blood group discrepancy or problems during compatibility testing were encountered with these (A1 antibody positive) blood units. Thus, it may be concluded that in India and other developing countries where resources are scarce, routine subgrouping of A and AB may not be really worthwhile unless there is a group discrepancy, problem during compatibility testing or history of a transfusion reaction.

QDs present some advantages when compared to organic dyes, such as size-tunable emission spectra, broad absorption bands, and principally exceptional resistance to photobleaching. Methods applying QDs can be simple, not laborious, and can present high sensibility, allowing biomolecule identification and quantification with high specificity. In this context, the aim of this work was to apply dual-color CdTe QDs to quantify red blood cell (RBC antigen expression on cell surface by flow cytometric analysis. QDs were conjugated to anti-A or anti-B monoclonal antibodies, as well as to the anti-H (Ulex europaeus I lectin, to investigate RBCs of A1, B, A1B, O, A2, and Aweak donors. Bioconjugates were capable of distinguishing the different expressions of RBC antigens, both by labeling efficiency and by flow cytometry histogram profile. Furthermore, results showed that RBCs from Aweak donors present fewer amounts of A antigens and higher amounts of H, when compared to A1 RBCs. In the A group, the amount of A antigens decreased as A1 > A3 > AX = Ael, while H antigens were AX = Ael > A1. Bioconjugates presented stability and remained active for at least 6 months.

    Arthur Mourant's The Distribution of the Human Blood Groups (1954) was an "indispensable" reference book on the "anthropology of blood groups" containing a vast collection of human genetic data. It was based on the results of blood-grouping tests carried out on half-a-million people and drew together studies on diverse populations around the world: from rural communities, to religious exiles, to volunteer transfusion donors. This paper pieces together sequential stages in the production of a small fraction of the blood-group data in Mourant's book, to examine how he and his colleagues made genetic data from people. Using sources from several collecting projects, I follow how blood was encountered, how it was inscribed, and how it was turned into a laboratory resource. I trace Mourant's analytical and representational strategies to make blood groups both credibly 'genetic' and understood as relevant to human ancestry, race and history. In this story, 'populations' were not simply given, but were produced through public health, colonial and post-colonial institutions, and by the labour and expertise of subjects, assistants and mediators. Genetic data were not self-evidently 'biological', but were shaped by existing historical and geographical identities, by political relationships, and by notions of kinship and belonging.

Among 240 positive and negative typing-discordant blood speciments from patients examined by Gel card, 107 blood speciments were positive and negative consistent examined by false agglutination test (44.58%), 133 blood specinents were discordent examined by false agglutination (55.42%), out of them, 35 cases (14.58%) with inconsistent cold agglutination test, 22 cases (9.17%) with weakened AB antigenicity, 16 cases (6.67%) with ABO subtyping, 12 cases (5.00%) with positive direct antiglobulin test, 11 cases (4.58%) with reduced or without antibodies, 11 cases (4.58%) with false aggregation caused by drugs or protein, 11 cases (4.58%) with salivary blood-type substances, 8 cases (3.33%) with non-ABO alloantibody, and 7 cases (2.92%) with allogeneic bone marrow transplantation. The distribution of disease were following: blood disease (16.83%), tumor (11.88%), and cardiopulmonary diseases (11.39%); chi-square test results indicated that the distribution significantly different. The analysis of ABO blood grouping shows a variety factors influencing positive and negative blood typing, and the Gel Card identification can produc more false positive blood types. Therefore, more attention should be paid on the high incidence diseases, such as blood disease, tumor, and cardiopulmonary disease.

    The ABO blood group locus was recently found to contribute independently and via interactions with angiotensin-converting enzyme (ACE) gene variation to plasma levels of ACE. Variation in ACE has previously been not only implicated as individually conferring susceptibility for Alzheimer's disease (AD) but also proposed to confer risk via interactions with other as yet unknown genes. More recently, larger studies have not supported ACE as a risk factor for AD, whereas the role of ACE pathway in AD has come under increased levels of scrutiny with respect to various aspects of AD pathology and possible therapies. We explored the potential combined involvement of ABO and ACE variations in the genetic susceptibility of 2067 AD cases compared with 1376 nondemented elderly. Including the effects of ABO haplotype did not provide any evidence for the genetic association of ACE with AD. Copyright © 2015 Elsevier Inc. All rights reserved.

    Different ethnicities have different distribution of Duffy blood group (DBG) phenotypes and different breast cancer morbidity. A study in our lab demonstrated that Duffy antigen/receptor for chemokines (DARC, also known as DBGP, the Duffy protein phenotype), led to the inhibition of tumorigenesis. Therefore, we tested the hypothesis that DBGP is correlated with breast cancer occurrence. DBGP proteins were examined by indirect antiglobulin testing with anti-FYa and anti-FYb antibodies. The phenotypes were classified into four groups according to the agglutination reactions: FYa + FYb+, FYa + FYb-, FYa-FYb + and FYa-FYb-. The phenotypes and pathological diagnosis of consecutively hospitalized female patients (n = 5,022) suffering from breast cancer at the Shanghai Cancer Hospital and Henan Province Cancer Hospital were investigated. The relationships between DBGP expression with breast cancer occurrence, axillary lymph status, histological subtype, tumor size pathological grade and overall survival were analyzed. The incidence of breast cancer was significantly different between FYa + FYb + (29.8%), FYa + FYb- (33.2%), FYa-FYb + (45.6%) and FYa-FYb- (59.1%; P = 0.001). Significant different numbers of breast cancer patients had metastases to the axillary lymph nodes in the FYa + FYb + group (25.1%), FYa + FYb- (36.9%), FYa-FYb + (41.0%) and FYa-FYb- (50.0%, (P = 0.005). There was a statistical significance (p = 0.022) of the overall survival difference between patients with difference phenotypes. No significant difference was observed in cancer size (t-test, p > 0.05), histological cancer type (Fisher's exact test, p > 0.05) or histological grade (Fisher's exact test, p > 0.05) between every each DBGP group. DBGP is correlated with breast cancer incidence and axillary lymph node metastasis and overall survival. Further investigations are required to determine the underlying mechanism of Duffy blood group phenotype on breast cancer risk

    Blood groups are an obstacle to reproduction, transfusion and transplantation. There are immunological abortions due to the antibodies of "p" phenotype women; and Rh haemolytic disease of the new-born is in direct proportion to the frequency of the "r" gene in a given population; the problem of transfusional allo-immunisation is completely parallel. Certain membrane anomalies (due to exceptional erythrocyte blood groups--Rh null, Rh mod or McLeod, for example), can provoke hemolytic anaemias, but in these cases the subjects are scattered throughout the world. An important problem is that of the relationships between Duffy antigens and malaria: from what is known about plasmodium Knowlesi, Fya and Fyb antigens are related to the erythrocyte receptors for this plasmodium: the Fy(a-b-) red cells, even of exceptional non-blacks, are not infested with parasites. Two kinds of receptors are postulated: one for adherence and another for penetration. In contrast, plasmodium falciparum does not recognise the same receptors as plasmodium Knowlesi. Experiments carried out on man have led to the conclusion that plasmodium vivax also used Fya and Fyb antigens to penetrate the red cell. These recent facts give rise to the problem of a possible natural selection by plasmodium vivax, which would eradicate polymorphism, whilst until now, the facts concerning plasmodium falciparum have explained the balance of polymorphism.

    Blood group incompatible transplantation (ABOi) in children is rare as pretransplant conditioning remains challenging and concerns persist about the potential increased risk of rejection. We describe the results of 11 ABOi pediatric renal transplant recipients in the 2 largest centers in the United Kingdom, sharing the same tailored desensitization protocol. Patients with pretransplant titers of 1 or more in 8 received rituximab 1 month before transplant; tacrolimus and mycophenolate mofetil were started 1 week before surgery. Antibody removal was performed to reduce titers to 1 or less in 8 on the day of the operation. No routine postoperative antibody removal was performed. Death-censored graft survival at last follow-up was 100% in the ABOi and 98% in 50 compatible pediatric transplants. One patient developed grade 2A rejection successfully treated with antithymocyte globulin. Another patient had a titer rise of 2 dilutions treated with 1 immunoadsorption session. There was no histological evidence of rejection in the other 9 patients. One patient developed cytomegalovirus and BK and 2 others EBV and BK viremia. Tailored desensitization in pediatric blood group incompatible kidney transplantation results in excellent outcomes with graft survival and rejection rates comparable with compatible transplants.

    Full Text Available Platelet transfusions have contributed to the revolutionary modern treatment of hypoproliferative thrombocytopenia. Despite the long-term application of platelet transfusion in therapeutics, all aspects of their optimal use (i.e., in cases of ABO and/or Rh (D incompatibility have not been definitively determined yet. We reviewed the available data on transfusion practices and outcome in ABO and RhD incompatibility and platelet refractoriness due to anti-human leukocyte antigen (HLA antibodies. Transfusion of platelets with major ABO-incompatibility is related to reduced posttransfusion platelet (PLT count increments, compared to ABO-identical and minor, but still are equally effective in preventing clinical bleeding. ABO-minor incompatible transfusions pose the risk of an acute hemolytic reaction of the recipient that is not always related to high anti-A, B donor titers. ABO-identical PLT transfusion seems to be the most effective and safest therapeutic strategy. Exclusive ABO-identical platelet transfusion policy could be feasible, but alternative approaches could facilitate platelet inventory management. Transfusion of platelets from RhD positive donors to RhD negative patients is considered to be effective and safe though is associated with low rate of anti-D alloimmunization due to contaminating red blood cells. The prevention of D alloimmunization is recommended only for women of childbearing age. HLA alloimmunization is a major cause of platelet refractoriness. Managing patients with refractoriness with cross-matched or HLA-matched platelets is the current practice although data are still lacking for the efficacy of this practice in terms of clinical outcome. Leukoreduction contributes to the reduction of both HLA and anti-D alloimmunization.

    This work aims to explain the complexity of the Knops blood group system in the Chinese population. The Knops blood group system consists of antigens encoded by CR1 gene exon 29. A total of 281 individuals from the Han, Uigur, Tu, Lisu and Dong ethnic groups were studied. The coding region of the CR1 gene of 11 Han donors was analysed using reverse transcription-polymerase chain reaction (PCR) and sequencing. CR1 gene exon 29 in the 39 samples was analysed through genomic DNA sequencing. According to the sequencing result, a PCR-sequence-specific primers system was designed to screen the A4646G and A4870G alleles in the Chinese population. Twelve single nucleotide polymorphisms (SNPs) were observed in the coding region of the CR1 gene in the Han population. Two SNPs (A4646G and A4870G) were detected in the CR1 gene exon 29. The 4646G allele was found only in the Uigur and Tu ethnic groups, in which the allele frequencies were 0·11 and 0·06, respectively. The frequencies of the 4870A allele in the Han, Uigur, Tu, Lisu and Dong ethnic groups were 0·82, 0·83, 0·82, 0·57 and 0·57, respectively. The CR1 gene in the Chinese people is more conservative than that in the Caucasian or African people. Different Chinese ethnic groups may have their own different CR1 gene characteristics. The existence of 4646G in the Uigur and Tu ethnic groups suggests that both may carry certain Caucasian characteristics in the CR1 gene. The frequency of 4870G in the Lisu and Dong ethnic groups implies possible incidence of evolutionary pressure similar to what the Africans had experienced. © 2010 The Authors.

Early reports suggest that patients who have elevated serum anti-blood group antibody titers (anti-A/B before transplantation and a rebound antibody production after antibody removal may be at high immunological risk. With currently available immune modulation protocols and immunosuppressive therapy, excellent short- and long-term patient and graft survival rates have been achieved even in those with high anti-A/B antibody titers before plasmapheresis or immunoadsorption. Nonetheless, acute infection with an organism possessing surface markers analogous to blood group antigens such as carbohydrate structures on

    Recent studies have suggested ABO blood type locus as an inherited predictor of thrombosis, cardiovascular risk factors, myocardial infarction. However, data is scarce about the impact of non-O blood groups on prognosis in patients with ST-elevation myocardial infarction (STEMI). Therefore, we aimed to evaluate the prognostic importance of non-O blood groups in patients with STEMI undergoing primary percutaneous coronary intervention (pPCI) METHODS: 1835 consecutive patients who were admitted with acute STEMI between 2010 and 2015 were included and followed-up for a median of 35.6months. The prevalence of hyperlipidemia, total cholesterol, LDL, peak CKMB and no-reflow as well as hospitalization duration were higher in patients with non-O blood groups. Gensini score did not differ between groups. During the in-hospital and long-term follow-up period, MACE, the prevalence of stent thrombosis, non-fatal MI, and mortality were higher in non-O blood groups. In multivariate logistic regression analysis, non-0 blood groups were demonstrated to be independent predictors of in-hospital (OR:2.085 %CI: 1.328-3.274 p=0.001) and long term MACE (OR:2.257 %CI: 1.325-3.759 pblood group compared with O blood group (pblood groups were determined to be significant prognostic indicators of short- and long-term cardiovascular adverse events and mortality in patients with STEMI undergoing pPCI. In conjunction with other prognostic factors, evaluation of this parameter may improve the risk categorization and tailoring the individual therapy and follow-up in STEMI patient population.

    We have developed a high-throughput system for single nucleotide polymorphism (SNP) genotyping of alleles of diverse blood group systems exploiting Luminex technology. The method uses specific oligonucleotide probes coupled to a specific array of fluorescent microspheres and is designed for typing Jk(a)/Jk(b), Fy(a)/Fy(b), S/s, K/k, Kp(a)/Kp(b), Js(a)/Js(b), Co(a)/Co(b) and Lu(a)/Lu(b) alleles. Briefly, two multiplex PCR reactions (PCR I and PCR II) according to the laboratory specific needs are set up. PCR I amplifies the alleles tested routinely, namely Jk(a)/Jk(b), Fy(a)/Fy(b), S/s, and K/k. PCR II amplifies those alleles that are typed less frequently. Biotinylated PCR products are hybridized in a single multiplex assay with the corresponding probe mixture. After incubation with R-phycoerythrin-conjugated streptavidin, the emitted fluorescence is analyzed with Luminex 100. So far, we have typed more than 2,000 subjects, 493 of whom with multiplex assay, and there have been no discrepancies with the serology results other than null and/or weak phenotypes. The cost of consumables and reagents for typing a single biallelic pair per sample is less than EUR 3.-, not including DNA extraction costs. The capability to perform multiplexed reactions makes the method markedly suitable for mass screening of red blood cell alleles. This genotyping approach represents an important tool in transfusion medicine.

  13. Duffy blood group antigens: structure, serological properties and function

    Full Text Available Duffy (Fy blood group antigens are located on seven-transmembrane glycoprotein expressed on erythrocytes and endothelial cells, which acts as atypical chemokine receptor (ACKR1 and malarial receptor. The biological role of the Duffy glycoprotein has not been explained yet. It is suggested that Duffy protein modulate the intensity of the inflammatory response. The Duffy blood group system consists of two major antigens, Fya and Fyb, encoded by two codominant alleles designated FY*A and FY*B which differ by a single nucleotide polymorphism (SNP at position 125G>A of the FY gene that results in Gly42Asp amino acid change in the Fya and Fyb antigens, respectively. The presence of antigen Fya and/or Fyb on the erythrocytes determine three Duffy-positive phenotypes: Fy(a+b-, Fy(a-b+ and Fy(a+b+, identified in Caucasian population. The Duffy-negative phenotype Fy(a-b-, frequent in Africans, but very rare in Caucasians, is defined by the homozygous state of FY*B-33 alleles. The FY*B-33 allele is associated with a SNP -33T>C in the promoter region of the FY gene, which suppresses erythroid expression of this gene without affecting its expression in other tissues. The FY*X allele, found in Caucasians, is correlated with weak expression of Fyb antigen. Fyx antigen differs from the native Fyb by the Arg89Cys and Ala100Thr amino acid substitutions due to SNPs: 265C>T and 298G>A in FY*B allele. The frequency of the FY alleles shows marked geographic disparities, the FY*B-33 allele is predominant in Africans, the FY*B in Caucasians, while the FY*A allele is dominant in Asians and it is the most prevalent allele globally.

    The novel erythrocyte ganglioside which carries the blood group Cad determinant has been isolated, and its structure has been determined. The ganglioside contained Glu:Gal:GalNAc:GlcNAc in a molar ratio of 1.00:1.94:0.93:0.95. The ganglioside binds Helix pomatia lectin and its chromatographic mobility is similar to G/sub D3/. After treatment with β-hexosaminidase (human placenta HexA) the product migrated with sialosylparagloboside (SPG), no longer binds Helix lectin, and binds a human anti-SPG antibody. Treatment of this material with neuraminidase (V. cholera) yielded a product with the mobility of paragloboside that bound monoclonal antibody 1B2. NMR analysis revealed that the terminal GalNAc is linked β1-4 to Gal, and confirms the structure proposed previously: GalNAcβ1-4(NeuAcα2-3)Galβ1-4GlcNAcβ1-3Galβ1-4Glc-Cer. This structure is consistent with the previous demonstration that a compound with the same chromatographic mobility as the Cad ganglioside could be synthesized by enzymatic transfer of GalNAc to sialosylparagloboside

    To evaluate carboxyhemoglobin (COHb) values measured with a CO-oximeter (Roche-cobas b 221) in jaundiced newborns with or without hemolysis and healthy controls in order to assess whether COHb measurement determined with a CO-oximeter could be used as an indicator of hemolysis in newborns with ABO alloimmunization. A total of 86 term newborn infants were prospectively studied. The study cohort consisted of three subgroups: 18 infants with ABO HDN, 21 infants with hyperbilirubinemia without hemolytic disease who required phototherapy, and 47 healthy controls. The COHb, bilirubin, and Hb levels were measured. The three subgroups did not differ significantly with respect to birth weight, gestational age, gender, Apgar score, or mode of delivery. The ABO HDN infants had significantly higher COHb values than the healthy controls (median 2.4% versus 1.3%, p < 0.0005) and the group with hyperbilirubinemia without hemolytic disease (median 2.4% versus 1.3%, p < 0.0005), although the infants with hyperbilirubinemia without hemolytic disease did not have significantly higher COHb values compared with the healthy controls. The cut-off value of 1.7% COHb had 72% sensitivity and 97% specificity for confirming hemolysis in ABO alloimmunization. Our data show that COHb values determined with CO-oximeters are higher in newborns with hemolysis than in those without hemolysis. COHb measured with CO-oximeters could be used to confirm hemolysis in infants with ABO alloimmunization.

    Blood group incompatibility in kidney transplants from a living donor can be successfully overcome by using various desensitization protocols: intravenous immunoglobulin, plasmapheresis (PP), immunoadsorption, and double filtration PP. From July 2010 to October 2013, we performed 10 ABO incompatible kidney transplantation (KT) procedures from a living donor. The desensitization protocol was based on rituximab and PP+cytomegalovirus immune globulin. All patients received induction with basiliximab, except 1 case treated with Thymoglobuline® (ATG) for the simultaneous presence of donor-specific antibody. Tacrolimus and mycophenolate mofetil were initiated at the time of desensitization and continued after the transplant. After a mean follow-up of 11.6±10.4 months, all patients are alive with a functioning graft. The mean serum creatinine concentration at 1 month, 3 months, 6 months, and 1 year was 1.48±0.29, 1.47±0.18, 1.47±0.27, and 1.5±0.27 mg/dl. Three episodes of acute cellular rejection occurred in 2 patients. There was only 1 case of BK virus infection, treated with reduction of immunosuppressive therapy. The protocol biopsy specimens at 1, 3, and 6 months were C4d positive in the absence of acute rejection. Desensitization with rituximab, PP, and anti-cytomegalovirus immune globulin allowed us to perform transplants from living donors to ABO incompatible recipients with excellent results and reduced costs.

  17. Advances in Blood Typing.

    Science.gov (United States)

    Quraishy, N; Sapatnekar, S

    The clinical importance of blood group antigens relates to their ability to evoke immune antibodies that are capable of causing hemolysis. The most important antigens for safe transfusion are ABO and D (Rh), and typing for these antigens is routinely performed for patients awaiting transfusion, prenatal patients, and blood donors. Typing for other blood group antigens, typically of the Kell, Duffy, Kidd, and MNS blood groups, is sometimes necessary, for patients who have, or are likely to develop antibodies to these antigens. The most commonly used typing method is serological typing, based on hemagglutination reactions against specific antisera. This method is generally reliable and practical for routine use, but it has certain drawbacks. In recent years, molecular typing has emerged as an alternative or supplemental typing method. It is based on detecting the polymorphisms and mutations that control the expression of blood group antigens, and using this information to predict the probable antigen type. Molecular typing methods are useful when traditional serological typing methods cannot be used, as when a patient has been transfused and the sample is contaminated with red blood cells from the transfused blood component. Moreover, molecular typing methods can precisely identify clinically significant variant antigens that cannot be distinguished by serological typing; this capability has been exploited for the resolution of typing discrepancies and shows promise for the improved transfusion management of patients with sickle cell anemia. Despite its advantages, molecular typing has certain limitations, and it should be used in conjunction with serological methods. © 2016 Elsevier Inc. All rights reserved.

    Sickle cell disease (SCD) is common in the Arabian Gulf region. Most cases require a red blood cell (RBC) transfusion, increasing the potential for RBC alloantibody development. The incidence of RBC alloimmunization among Kuwaiti Arab SCD patients is not yet known. This study retrospectively assessed the effect of using two different matching protocols on the incidence of alloimmunization among multiply transfused Kuwaiti Arab SCD patients. A total of 233 Kuwaiti Arab SCD patients were divided into two groups: Group 1 (n = 110) received RBC transfusion through standard ABO- and D-matched nonleukoreduced blood; Group 2 (n = 123) received RBCs matched for ABO, Rh, and K1 poststorage-leukoreduced blood. Multivariate analysis was performed on the factors associated with RBC alloimmunization and antibody specificity. Sixty-five percent of patients in Group 1 developed clinically significant RBC alloantibody with an increased prevalence in females; in patients in Group 2, 23.6% developed RBC alloantibodies (p = 0.01). In Group 1, 72 patients (65.5%) had alloantibodies directed against Rh and Kell systems (p = 0.01). Multivariate analysis further confirmed the results, showing that blood transfusion type and sex have significant effects on the rate of alloimmunizations. This study confirms the importance of selecting RBCs matched for Rh and Kell to reduce the risk of alloimmunizations among Kuwaiti Arab SCD patients.

    Objective: To explore the distribution of ABO blood group in the healthy population in the Ali area of Tibet, and to analyze the difference of blood group distribution between the Tibetan population in Ali and the Tibet Tibetan population. Methods: The blood distribution of 509 apparent healthy volunteers of Tueti County and Gal County, Tibet, which were randomly selected from September to November in 2016; 137 Tibetan blood donors, from 2016 September to2017 July and 84 Tibetan blood donors from 2015 August to 2017 July was analyzed retrospectively. The blood type was tested by the slide method. By reviewing the Chinese and foreign language database, seven articles on Tibetan blood group distribution were obtained. And the data of the blood distribution of the Ali area population and the Tibet Tibetan population were compared. Results: The ABO phenotype frequencies of 507 apparent healthy people, 137 blood donors and 84 recipients were B>O>A>AB. The composition ratio were 36.1%, 34.5%, 21.5 %, 7.9%; 40.1%, 35.0%, 17.5%, 7.3%; 39.3%, 34.5%, 20.2%, 6.0%.There was no statistically significant difference in blood group distribution between the donors and the recipients ( P >0.05). And there was no significant difference in the blood group distribution between Ali and Shigatse, Nagqu, Lhasa, Shannan. However, the differences between Ali and Qamdo, Nyingchi areas were statistically significant.

    The study presented here has lead to the implementation of real time image analysis system. The image data analysis system consists of a motorised microscope, a C.C.D. array sensor, a reprocessing hardware, a processing and management microprocessor and a printer. The various immuno-haematology tests are carried out according to micro-methods, into the wells of a 'Terasaki' plate. The rate of reaction is qualitatively and quantitatively estimated. The originality of the described system is: the adaptation of the micromethod to all biological tests carried by the system; the fast reading of the biological tests (ABO-Rhesus grouping per patient in 12 seconds); the determination and implementation of a wired algorithm for the correction of the C.C.D. array sensor non-linearities.

  10. Blood group genotyping: from patient to high-throughput donor screening.

    Science.gov (United States)

    Veldhuisen, B; van der Schoot, C E; de Haas, M

    2009-10-01

    Blood group antigens, present on the cell membrane of red blood cells and platelets, can be defined either serologically or predicted based on the genotypes of genes encoding for blood group antigens. At present, the molecular basis of many antigens of the 30 blood group systems and 17 human platelet antigens is known. In many laboratories, blood group genotyping assays are routinely used for diagnostics in cases where patient red cells cannot be used for serological typing due to the presence of auto-antibodies or after recent transfusions. In addition, DNA genotyping is used to support (un)-expected serological findings. Fetal genotyping is routinely performed when there is a risk of alloimmune-mediated red cell or platelet destruction. In case of patient blood group antigen typing, it is important that a genotyping result is quickly available to support the selection of donor blood, and high-throughput of the genotyping method is not a prerequisite. In addition, genotyping of blood donors will be extremely useful to obtain donor blood with rare phenotypes, for example lacking a high-frequency antigen, and to obtain a fully typed donor database to be used for a better matching between recipient and donor to prevent adverse transfusion reactions. Serological typing of large cohorts of donors is a labour-intensive and expensive exercise and hampered by the lack of sufficient amounts of approved typing reagents for all blood group systems of interest. Currently, high-throughput genotyping based on DNA micro-arrays is a very feasible method to obtain a large pool of well-typed blood donors. Several systems for high-throughput blood group genotyping are developed and will be discussed in this review.

  11. Is group A thawed plasma suitable as the first option for emergency release transfusion? (CME).

    2014-07-01

    Group AB plasma, which lacks anti-A and anti-B isohemagglutinins, is issued for emergency transfusion when a patient's ABO group is unknown, but the relative scarcity of group AB blood donors limits its availability. We sought to establish a thawed plasma inventory to improve the rapid availability of plasma in the emergency release setting but were concerned about potential wastage of group AB plasma. Recognizing that plasma-incompatible apheresis platelets are routinely transfused and only rarely result in hemolytic reactions if the donor is blood group O, and considering that group A plasma would be compatible with approximately 85% of our patient population, we instituted an emergency release policy whereby thawed group A plasma is issued to all patients of unknown blood group or if compatible plasma is not available. ABO-compatible plasma is then issued, if needed, once the patient's blood group is determined. We prospectively assessed the outcomes of all patients who received incompatible plasma under our policy. During the first 5 years under this policy, 385 emergency release requests for plasma were received by our blood bank. Among them, 23 group B or AB patients met criteria for receiving a median of 2 units of incompatible group A plasma. No hemolytic transfusion reactions or other adverse events related to transfusion were seen in any of these 23 patients. We propose that group A plasma may be an acceptable alternative to AB plasma as the first option in the emergency release setting. © 2014 AABB.

    2018-02-01

    Full Text Available Objective: Any erythrocyte transfusion among humans having type A or B blood groups is impossible due to antibodies causing fatal transfusion complications. A cross-match test is performed to prevent immune transfusion complications before transfusion. Our hypothesis is that the fragment antibody (Fab part of the antibody (incomplete antibody may be used to prevent an immune stimulus related to the complete antibody. Therefore, we designed a pilot study to evaluate the effectiveness of these incomplete antibodies using cross-match tests. Materials and Methods: Pepsin enzyme and staphylococcal protein A columns were used to cut anti-A and anti-B monoclonal antibodies and purify their Fab (2 fragments, respectively. An Rh-positive erythrocyte suspension with purified anti-A Fab (2 solution and B Rh-positive erythrocyte suspension with purified anti-B Fab (2 solution were combined correspondingly. Cross-match tests were performed by tube and gel centrifugation methods. The agglutination levels due to the anti-A and anti-B Fab (2 antibodies and their effects on the agglutination normally observed with complete antibodies were then measured. Results: No agglutination for the purified incomplete anti-A Fab (2 with A Rh+ erythrocyte and anti-B Fab (2 with B Rh+ erythrocyte combinations was observed in the tube cross-match tests. These agglutination levels were 1+ in two wells in the gel centrifugation cross-match tests. Fab (2-treated erythrocytes were also resistant to the agglutination that normally occurs with complete antibodies. Conclusion: We determined that the Fab (2 fragments of antibodies may not only be used to obtain a mild or negative reaction when compared to complete antibodies, but they might also be used for decreasing ABO incompatibility. Incomplete antibodies might be a therapeutic option in autoimmune hemolytic anemia and they may also be used in solid organ or hematopoietic stem cell transplantation. Therefore, we have planned an

    The aim of the study was to investigate the relationship between oral Candida carriage and the secretor status of blood group antigens. Unstimulated whole saliva and oral rinse samples were obtained from 180 healthy subjects. These samples were plated on Sabouraud's dextrose agar media to determine oral Candida carriage. Sodium dodecylsulfate polyacrylamide gel electrophoresis and immunoblotting were performed on whole saliva samples to determine the secretor status of blood group antigens. The oral Candida carriage rate was found to be 45.0%. The sensitivity of the concentrated rinse culture proved to be superior. Oral Candida carriage was not significantly related to the blood group or secretor status of ABH or Lewis antigens. No significant relationship was found between oral Candida carriage and salivary flow rate. However, smoking affected oral Candida carriage. Oral Candida carriage in healthy individuals is not significantly related to blood group or secretor status.

  2. SINGLE-CENTER EXPERIENCE OF ABO-INCOMPATIBLE LIVER TRANSPLANTATION

    Directory of Open Access Journals (Sweden)

    S. V. Gautier

    2011-01-01

    Full Text Available Since 2008 up to 2010 eight ABO-incompatible liver transplantations have been performed in our center: one of them was urgent liver transplantation to adult patient from deceased donor, other seven were transplantations of left lateral segment to children from living relative donors. Own experience, as well as world one, proves, that barrier of ABO-incompatibility can be overcome more successfully in liver transplantation, particularly in pediatric population, that in other solid organs transplantation. Good results can be achieved even with less ag- gressive immunosuppressive therapy. Recipient conditioning before operation can significantly improve results of ABO-incompatible liver transplantation, but as own experience has shown, often there’s no need to hold some special preparation of children, because their anti-ABO antibodies are very low or absent before transplantation and do not increase after it. Thereby ABO-incompatible liver transplantation is reasonable in urgent cases and in pediatric population because of the limited pull of living relative donors for children.

    Emergency patients with unknown blood type usually receive O Rhesus D negative (RhD-) red blood cell concentrates until their blood group is determined to prevent RhD+ related adverse transfusion reactions. As 85% of individuals are RhD+, this consumption of O RhD- red blood cell concentrates contributes to shortages of O RhD- red blood cell concentrates, sometimes forcing transfusion of known RhD- patients with RhD+ red blood cell concentrates. Here we report the outcome of this transfusion policy transfusing all emergency patients with unknown blood type with O RhD+ red blood cell concentrates. In this prospective single-centre observational study done between Jan 1, 2001, and Dec 31, 2015, we assessed all consecutive RhD- patients at the University Medicine Greifswald who received RhD+ red blood cell concentrates (emergency patients with unknown blood type; and RhD- patients receiving RhD+ red blood cell concentrates during RhD- red blood cell concentrate shortages). No patients were excluded. The primary endpoint was anti-D allo-immunisation at 2 months follow-up or later. Patients were followed up and tested for immunisation against red blood cell antigens using the direct antiglobulin test and an antibody screen every 3-5 days for 4 weeks or until death, or hospital discharge. Surviving patients were screened for development of anti-D antibodies for up to 12 months (at the predefined timepoints 2, 3, 6, and 12 months) after RhD+ red blood cell transfusion. 437 emergency patients, of whom 85 (20%) were RhD-, received 2836 RhD+ red blood cell concentrates. The overall risk of inducing anti-D antibodies (in all 437 recipients) was 17 (4%, 95% CI 2·44-6·14) of 437 (assuming all patients lost to follow-up developed anti-D allo-immunisation). During this period, 110 known RhD- patients received RhD+ red blood cell concentrates during RhD- red blood cell concentrate shortages. Of these, 29 (26%; 95% CI 19·0-35·3) developed anti-D allo-immunisation (assuming all

    This study explores the genetic admixture of eight Mexican indigenous populations (Otomi-Ixmiquilpan, Otomi-Actopan, Tzeltales, Nahua-Milpa-Alta, Nahua-Xochimilco, Nahua-Zitlala, Nahua-Ixhuatlancillo, and Nahua-Coyolillo) on the basis of five PCR-based polymorphic DNA loci (LDLR, GYPA, HBGG, D7S8, GC), HLA_DQA1, and the blood groups ABO and Rh (CcDEe). Among the indigenous populations, the highest gene frequencies for O and D were 0.9703 and 1.000 for Zitlala (State of Guerrero) and 0.9955 and 0.9414 for Tzeltales (State of Chiapas), respectively. Maximum likelihood estimates of admixture components yield a trihybrid model with Amerindian (assuming that Nahua-Zitlala is the most representative indigenous population), Spanish, and African ancestry with the admixture proportions: 93.03, 6.03, and 0.94 for Tzeltales, and 28.99, 44.03, and 26.98 for Coyolillo. A contribution of the ancestral populations of Ixhuatlancillo, Actopan, Ixmiquilpan, Milpa-Alta, and Xochimilco were found with the following average of admixture proportions: 75.84, 22.50, and 1.66. The findings herein demonstrate that the genetic admixture of the Mexican indigenous populations who at present speak the same Amer-Indian language can be differentiated and that the majority of them have less ancestral indigenous contribution than those considered as Mestizo populations.

    Accurate and reliable blood grouping is essential for safe blood transfusion. However, conventional methods are qualitative and use only single-antigen detection. We overcame these limitations by developing a simple, quantitative, and multiplexed detection method for blood grouping using quantum dots (QDs) and magnetic beads. In the QD fluorescence assay (QFA), blood group A and B antigens were quantified using QD labeling and magnetic beads, and the blood groups were identified according to the R value (the value was calculated with the fluorescence intensity from dual QD labeling) of A and B antigens. The optimized performance of QFA was established by blood typing 791 clinical samples. Quantitative and multiplexed detection for blood group antigens can be completed within 35 min with more than 10 5 red blood cells. When conditions are optimized, the assay performance is satisfactory for weak samples. The coefficients of variation between and within days were less than 10% and the reproducibility was good. The ABO blood groups of 791 clinical samples were identified by QFA, and the accuracy obtained was 100% compared with the tube test. Receiver-operating characteristic curves revealed that the QFA has high sensitivity and specificity toward clinical samples, and the cutoff points of the R value of A and B antigens were 1.483 and 1.576, respectively. In this study, we reported a novel quantitative and multiplexed method for the identification of ABO blood groups and presented an effective alternative for quantitative blood typing. This method can be used as an effective tool to improve blood typing and further guarantee clinical transfusion safety.

    To determine an association between transmission of hepatitis B virus and secretor and non-secretor status of salivary blood group antigens. Study Design: Cross-sectional, analytical study. Place and Duration of Study: The Department of Physiology and Division of Hepatology, College of Medicine, King Khalid University Hospital, King Saud University, Riyadh, Kingdom of Saudi Arabia, from 2007 to 2009. Methodology: Eighty eight known patients, who were positive for Hepatitis B Surface Antigen [HBsAg] were recruited. Saliva was collected for investigating the secretor and non-secretor status by using blood typing kit number Kemtec Educational Science USA. Hepatitis B Surface antigen test was performed on Enzyme Linked Immunosorbent Assay technique. Polymerase chain reaction [PCR] on saliva was also carried out in High Performance Thermal Cycler-Palm- Cycler [Corbett Life Science, Sydney, Australia] and enzymatic amplification of extracted viral DNA was performed using primers covering the promoter of the core region of HBV. Results: Out of the 88 subjects, 61 belong to blood group O, 20 to A and 7 subjects to blood group B. Fifty subjects were secretors [salivary blood group antigens positive] and 38 subjects were non-secretors [salivary blood group antigens negative]. Among core gene positive 25 (69.4%) were secretors and 11 (30.6%) were non-secretors. However, in core gene negative 25 (48.1%) were secretors and 27 (51.9%) were non-secretors. Conclusion: The result shows an association [p=0.047] between secretor and non-secretors status of the salivary blood group antigens with core gene positive and core gene negative. (author)

    Due to lack of correct blood grouping practices, the rare Bombay Oh phenotype may be missed, subjecting patients to the risk of severe hemolytic transfusion reaction. In the absence of blood donor registry, transfusion management of patients needing immediate surgery is a challenge. This study presents detection of rare Bombay Oh phenotype patients and their management by acute peri-operative acute normovolemic hemodilution (ANH) in a hospital from central India. Blood grouping of patients and blood donors with a standard tube method was carried out and samples identified as rare Bombay phenotype were confirmed by saliva inhibition test. Surgical management of cases needing transfusion was done by ANH, as per the British Committee for Standards in Hematology guidelines. The incidence of Bombay phenotype was 0.002% or 1 in 51,924 in the study. Amongst three cases (patients) identified as Bombay phenotype, one was Bombay Oh, Rh negative. Two cases were missed in the first instance and one case actually did not require transfusion. In the absence of a blood donor registry for Bombay phenotype, the cases needing transfusion were successfully managed with ANH in the operation theatre. A simple test like blood grouping should be done with serious intention with incorporation of both forward and reverse grouping, so that no patient receives wrong blood leading to fatal hemolysis due to transfusion. ANH is a cost-effective transfusion option for suitable patients. Appropriate clinical decision making, use of strategies to decrease peri-operative blood losses and cost-effective country based planning could be more widely applied to improve clinical transfusion practice.

A total of 2 015 blood samples from the blood donors were selected randomly to screen the presence of K⁺ and Kp(c+) (Kell), Yt(b+) (Yt), Co(b+) (Colton), Di(a+b+) and Di(a+b-) (Digeo) antigen allele by using PCR and multiplex PCR. Out of 2005 samples, 1 case with K⁺ gene, 8 cases with Yt(b+) gene and 100 cases with Di(a+b+) gene, 2 cases with Di(a+b-) were identified, while no Kp(c+) and Co(b+) were detected. The frequencies of K⁺, Yt(b+) and Di(a+), Di(b+) are 0.0003, 0.0013 and 0.0258, 0.9742, respectively. They are very rare blood groups in Chinese Nanjing Han population.

  11. Relevance of blood groups in transfusion of sickle cell disease patients.

    2013-03-01

    Blood groups are clinically significant in sickle cell disease (SCD) as transfusion remains a key treatment in this pathology. The occurrence of a delayed haemolytic transfusion reaction (DHTR) is not rare and is a life-threatening event. The main cause of DHTR is the production of alloantibodies against red blood cell antigens. The high rate of alloimmunization in SCD patients is mainly due to the differences of red blood groups between patients of African descent, and the frequently Caucasian donors. From an immuno-haematological point of view, DHTR in SCD patients has specific features: classical antibodies known to be haemolytic can be encountered, but otherwise non significant antibodies, autoantibodies and antibodies related to partial and rare blood groups are also frequently found in individuals of African descent. In some cases, there are no detectable antibodies. As alloimmunization remains the main cause of DHTR, it is extremely important to promote blood donation by individuals of African ancestry to make appropriate blood available.

    There has yet to be a comprehensive analysis of blood group antigen prevalence in Asian Americans and Native Americans. There may be ethnic differences in blood group frequencies that would result in clinically important mismatches through transfusion. Blood donors who self-identified as Asian or Native American were tested using a single-nucleotide polymorphism (SNP) DNA array (HEA BeadChip kit, Bioarray Solutions Ltd) that predicts expression of 38 human erythrocyte antigens (HEAs) and by serology for ABO, D, C, M, N, Jk(a) , and Jk(b) . The prevalence of blood group antigens was compared to published European prevalence. Discrepancies between SNP-predicted and serology-detected antigens were tallied. A total of 9087 blood donors were tested from nine Asian and Native American heritages. The predicted prevalence of selected antigens in the RHCE, JK, FY, MNS, LU, CO, and DO blood group systems were variable between Asian populations, but overall not significantly different than Europeans. Compared to European frequencies, Kell blood group allele frequencies were significantly different in the Chinese, Native American, Hawaiian/Pacific Islander, South Asian, and Southeast Asian heritage blood donors; Diego antigens Di(a) and Di(b) were different in donors of Native American and South Asian ancestries (p Asian and Native Americans donors. Several ethnic groups exhibited differences in HEA frequencies compared to Europeans. Genotype-serotype discrepancies were detected in all systems studied. © 2015 AABB.

    To compare the effect of a conventional to an intensive blood pressure monitoring regimen on blood pressure in hypertensive patients in the general practice setting. Randomized controlled parallel group trial with 12-month follow-up. One hundred and ten general practices in all regions of Denmark. One thousand forty-eight patients with essential hypertension. Conventional blood pressure monitoring ('usual group') continued usual ad hoc blood pressure monitoring by office blood pressure measurements, while intensive blood pressure monitoring ('intensive group') supplemented this with frequent home blood pressure monitoring and 24-hour ambulatory blood pressure monitoring. Mean day- and night-time systolic and diastolic 24-hour ambulatory blood pressure. Change in systolic and diastolic office blood pressure and change in cardiovascular risk profile. Of the patients, 515 (49%) were allocated to the usual group, and 533 (51%) to the intensive group. The reductions in day- and night-time 24-hour ambulatory blood pressure were similar (usual group: 4.6 ± 13.5/2.8 ± 82 mmHg; intensive group: 5.6 ± 13.0/3.5 ± 8.2 mmHg; P = 0.27/P = 0.20). Cardiovascular risk scores were reduced in both groups at follow-up, but more so in the intensive than in the usual group (P = 0.02). An intensive blood pressure monitoring strategy led to a similar blood pressure reduction to conventional monitoring. However, the intensive strategy appeared to improve patients' cardiovascular risk profile through other effects than a reduction of blood pressure. Clinical Trials NCT00244660. © The Author 2018.

    Osteoprotegerin (OPG) and von Willebrand factor (VWF) form complex within endothelial cells and following secretion. The nature of blood group antigens strongly influences the levels of circulating VWF, but there is no available data concerning its ascendancy on OPG levels. We aimed to assess the relationship of AB0 blood groups with OPG, VWF levels (VWF: Ag) and collagen binding activity (VWF: CB) in peripheral arterial disease (PAD) patients. Functional and laboratory parameters of 105 PAD patients and 109 controls were examined. Results of OPG, VWF: Ag, VWF: CB (ELISA-s) were analysed by comparative statistics, together with clinical data. OPG levels were higher in patients than in controls (4.64 ng/mL vs. 3.68 ng/mL, p blood groups compared to 0-groups both in patients and controls (4.95 ng/mL vs. 3.90 ng/mL, p = 0.012 and 4.09 ng/mL vs. 3.40 ng/mL, p = 0.002). OPG levels are associated to blood group phenotypes and higher in non-0 individuals. Increased OPG levels in PAD characterize disease severity. The significant correlation between OPG and VWF:CB might have functional importance in an atherothrombosis-prone biological environment.

    Objective: To analyze the patient and the graft survival of the first cohort of Brazilian patients receiving ABO-incompatible transplants. Patients and Methods: From October 2012 to June 2016, we performed 10 ABO incompatible kidney transplantation (KT procedures from a living donor. The desensitization protocol was based on rituximab and PP. All patients received induction with Thymoglobulin and long-term steroids. Tacrolimus and mycophenolate sodium were initiated at the time of desensitization and continued after the transplant. Pre-transplant agglutinin titers varied from 1/32 to 1/512. Five patients also presented anti-HLA specific antibodies, being three T and B positive FCXM at baseline. Results: After a mean follow-up of 30 ( ± 13 months, all patients are alive. One patient lost the graft due to cellular rejection that occurred after reduction of immunosuppressive therapy for an aggressive HPV-related vulvar cancer. The mean serum creatinine concentration is 1.4 ± 0.5 mg/dl. Three episodes of rejection occurred in 3 patients: two cellular and one anti-HLA mediated. Conclusion: Desensitization with Rituximab and PP allowed us to perform transplants from living donors to ABO incompatible recipients in a Brazilian population with good results, even in highly-sensitized patients and in those presenting high anti-ABO agglutinin titers.

    This study was aimed to review and establish the practice of exchange transfusion (ET) with reconstituted blood in neonates and to observe fall of bilirubin and its comparison with related studies. Twenty-five neonates diagnosed as hemolytic disease of newborn (HDN) were selected for this study, in which exchange transfusion was carried out as one of the treatments for hyperbilirubinemia. Out of the 25 cases, 15 were of Rhesus (Rh) HDN, while ABO and other blood groups constituted 6 and 4 HDN cases respectively. First, the neonates's and mother's blood samples were subjected to relevant investigations. After that, for neonates having Rh HDN, O Rh negative cells suspended in AB plasma were given, O Rh positive cells suspended in AB plasma were given to ABO HDN; and O positive cells, which were indirect Coomb's cross-matched compatible with neonates’ and mother's serum / plasma, suspended in AB plasma were given to the neonates having HDN because of other blood group antibodies. The exchange transfusion (ET) was carried out taking all aseptic precautions by Push-Pull technique with double-volume exchange transfusion method. The average post-exchange fall in serum indirect bilirubin was (52.01%) in all 25 cases, which was found to be more significant than the previous studies. Looking into the superiority of the exchange transfusion in HDN by reconstituted blood, the reconstituted blood can be modified and supplied as per the requirement and conditions. PMID:21938234

    Full Text Available Background: Diego blood group antigen, Di(a, is very rare among Caucasians and Blacks, but relatively common among the South American Indians and Asians of Mongolian origin. The antibody to Di(a is clinically significant to cause hemolytic disease in a new-born or hemolytic transfusion reaction. Objectives: This study was designed to determine the prevalence of Di(a antigen among the blood donors from the three major ethnic groups in Klang Valley of Malaysia as well as to find an incidence of an antibody of the Diego antigen, anti-Di(a, in a tertiary care hospital to ascertain the need to include Di(a+ red cells for an antibody screen cell panel. Materials and Methods: Serological tests were performed by column agglutination technique using commercial reagents and following instruction as per kit insert. Results: Di(a antigen was found with a frequency of 2.1% among the Malaysians donors in three ethnic groups viz, Malay, Chinese and Indian. It was present among 1.25% of 401 Malay, 4.01% of Chinese and 0.88% of 114 Indian origin donors. None of the 1442 patients, including 703 antenatal outpatients, had anti-Di(a in serum. Conclusion: The prevalence of Di(a antigen was found among the donors of all the three ethnic background with varying frequency. Inclusion of Di(a+ red cells in routine antibody screening program would certainly help in detection of this clinically significant antibody and to provide safe blood transfusion in the Klang Valley, though the incidence of antibody appears to be very low in the region.

    Full Text Available Providing information is not enough to improve diabetic patient’s compliance and achieve goals of therapy. Patient’s good awareness as well as emotional and social supports from family and community may play an important role to improve their compliance and clinical outcomes. Therefore, diabetes support groups were developed and each support group consisted of two pharmacists, two nurses, diabetic patients and their family members. A total of 70 type 2 diabetic patient’s were enrolled and randomized into support group 1 and support group 2. Patients in the group 1 received information leaflets only, while patient in the group 2 received pharmacist counselling and information leaflets at each meeting. Patient’s awareness of diabetes and compliance with medications were assessed by a short questionnaire at baseline and final follow-up. Blood glucose and cholesterol levels were also evaluated in both groups. At the end of study, the overall patient’s awareness and compliance improved by 61.5%. The random and fasting blood glucose levels decreased over than 30% in the group 2 and around 14% in the group 1. This study reveals that collaboration between health care professionals and community in the diabetes support group might help diabetic patients to increase their knowledge and compliance with the diabetes therapy as well as glycaemic control.

    Significant changes have been reported in dietary habits and food availability in Iceland that would be expected to compromise selenium intake and status, especially among young people. These include substantial decreases in the consumption of fish and milk, as well as the selenium content of imported wheat. The aim of this study was to assess selenium in the diet and whole blood of adolescent girls, as well as define the most important foods contributing to intake and blood concentrations of selenium. The subjects were 96 randomly selected girls, aged 16-20, who answered a validated food frequency questionnaire (FFQ) for dietary assessment. Selenium intake from each food group was calculated in µg/day. Blood samples were collected for measurement of whole blood selenium. Mean dietary selenium was 51±25 µg/day. Milk/dairy products, including cheese, contributed 36±14% of total dietary selenium; fish 18±12%; and bread/cereal products 13±6%. Mean whole blood selenium was 117±12 µg/l (range 90-208); nearly 90% of subjects were above the optimal level of 100 µg/l. Fish and bread/cereal products were the only foods significantly correlated with selenium in blood (r=0.32; P=0.002 and r=0.22; P=0.04, respectively) while no correlation was found with milk and dairy products in spite of their greater contribution to total selenium intake. In this population of Icelandic adolescent girls, selenium intake and status seem acceptable. Judging from associations between intake and blood levels, fish and cereals may be the most important contributors to blood selenium.

    AABB Standards specify that ABO group-specific whole blood is the only acceptable choice for whole blood transfusions. Although universal donor group O stored whole blood (SWB) was used extensively by the military during the wars of the mid-twentieth century, its use has fallen out of favor and has never been used to great extent in the civilian trauma population. Interest in the use of whole blood has been renewed, particularly in light of its potential value in far-forward military and other austere environments. Evidence of preserved platelet function in SWB has heightened enthusiasm for a "one stop shop" resuscitation product providing volume, oxygen carrying capacity, and hemostatic effects. Experience with universal donor group O SWB is required to ascertain whether its use will be an advance in trauma care. Described here is the process of establishing a universal donor group O SWB at a civilian trauma center in the United States. © 2016 AABB.

    The growing number of BMTs has increased interest in safe and standardized in vitro bone marrow processing techniques. We describe our experience with a rapid automated method for the isolation of mononuclear cells (MNC) from large volumes of bone marrow using a Fenwal CS-3000 cell separator without employing density gradient materials. Forty bone marrow harvests with a mean volume of 1650 +/- 307 ml were processed. A mean of 75 +/- 34% (50 percentile range 54-94%) of the original MNCs were recovered in a volume of 200 ml with only 4 +/- 2% of the starting red blood cells (RBC). Removal of granulocytes, immature myeloid precursors and platelets proved to be sufficient to permit safe cryopreservation and successful autologous BMT (n = 25). Allogeneic BMT (n = 14, including three major ABO-incompatible) could be performed without additional manipulation. In both groups of patients timely and stable engraftment comparable to historical controls receiving Ficoll gradient processed autologous (n = 17) or unprocessed allogeneic BMT (n = 54) was observed. Moreover, 70 +/- 14% of the RBC could be recovered from the grafts. They were used for autologous RBC support of donors, rendering unnecessary autologous blood pre-donations.

    ESSENTIALS: Targeting of factor VIII values is a challenge during perioperative replacement therapy in hemophilia. This study aims to identify the extent and predictors of factor VIII underdosing and overdosing. Blood group O predicts underdosing and is associated with perioperative bleeding. To increase quality of care and cost-effectiveness of treatment, refining of dosing is obligatory. Perioperative administration of factor VIII (FVIII) concentrate in hemophilia A may result in both underdosing and overdosing, leading to respectively a risk of bleeding complications and unnecessary costs. This retrospective observational study aims to identify the extent and predictors of underdosing and overdosing in perioperative hemophilia A patients (FVIII levels < 0.05 IU mL(-1)). One hundred nineteen patients undergoing 198 elective, minor, or major surgical procedures were included (median age 40 years, median body weight 75 kg). Perioperative management was evaluated by quantification of perioperative infusion of FVIII concentrate and achieved FVIII levels. Predictors of underdosing and (excessive) overdosing were analyzed by logistic regression analysis. Excessive overdosing was defined as upper target level plus ≥ 0.20 IU mL(-1). Depending on postoperative day, 7-45% of achieved FVIII levels were under and 33-75% were above predefined target ranges as stated by national guidelines. A potential reduction of FVIII consumption of 44% would have been attained if FVIII levels had been maintained within target ranges. Blood group O and major surgery were predictive of underdosing (odds ratio [OR] 6.3, 95% confidence interval [CI] 2.7-14.9; OR 3.3, 95% CI 1.4-7.9). Blood group O patients had more bleeding complications in comparison to patients with blood group non-O (OR 2.02, 95% CI 1.00-4.09). Patients with blood group non-O were at higher risk of overdosing (OR 1.5, 95% CI 1.1-1.9). Additionally, patients treated with bolus infusions were at higher risk of excessive

Here, we uncover a role for a conserved bromodomain AAA-ATPase, Abo1, in the maintenance of nucleosome architecture in fission yeast. Cells lacking abo1+ experience both a reduction and mis-positioning of nucleosomes at transcribed sequences in addition to increased intragenic transcription, phenotypes that are hallmarks of defective chromatin re-establishment behind RNA polymerase II.

    No comprehensive data on sources or risk factors of cadmium exposure in Ukrainian children are available. In this we measured the blood levels of cadmium among 80 Ukrainian children and evaluated sources of exposure. A nested case-control study from a prospective cohort of Ukrainian 3-year-old children was conducted. We evaluated predictors of elevated blood cadmium using a multivariable logistic regression model. The model included socioeconomic data, parent occupation, environmental tobacco smoke, hygiene, body-mass index, and diet. Dietary habits were evaluated using the 1992 Block-NCI-HHHQ Dietary Food Frequency survey. Elevated cadmium was defined as blood levels in the upper quartile (>=0.25μg/L). The mean age for all 80 children was 36.6 months. Geometric mean cadmium level was 0.21μg/L (range=0.11-0.42μg/L; SD=0.05). Blood cadmium levels were higher among children taking zinc supplements (0.25 vs 0.21μg/L; P=0.032), children who ate sausage more than once per week (0.23 vs 0.20; P=0.007) and children whose fathers worked in a by-product coking industry (0.25 vs 0.21; P=0.056). In the multivariable model, predictors of elevated blood cadmium levels included zinc supplementation (adjusted OR=14.16; P<0.01), father working in a by-product coking industry (adjusted OR=8.50; P=0.03), and low body mass index (<14.5; adjusted OR=5.67; P=0.03). This is the first study to indicate a strong association between elevated blood cadmium levels and zinc supplementation in young children. Whole-blood cadmium levels observed in this group of Ukrainian children appear to be similar to those reported in other Eastern European countries
