Abstract
Patient blood group (BG) is predictive for von-Willebrand-factor (VWF) and Factor VIII variation. The clinical impact of this ABO-effect on blood loss, cardiovascular complications and outcome has been described for several patient cohorts. The aim of this study was to investigate the impact of patient BG on blood loss and outcome after coronary artery bypass surgery (CABG). Patient records, intraoperative data and perioperative transfusion records of 5713 patients receiving an on-pump CABG procedure between 05/2004 and 12/2018 were analyzed. A logistic regression model for death due to perioperative myocardial ischaemia (PMI) was developed from initially 24 variables by using an univariate and multivariate selection process. BG AB patients required less blood transfusions as compared to the other blood groups, especially in case of emergency operations. However, BG AB patients also had a higher mortality which was due to secondary cardiovascular complications. The impact of blood type on the rate of cardiovascular mortality was confirmed in the logistic regression model. BG AB patients have a worse outcome after CABG surgery due to an increased incidence of fatal cardiovascular complications. As perioperative myocardial ischemia due to graft occlusion appears to be the most likely explanation, stricter anticoagulation for BG AB patients should be discussed.

Abstract
BACKGROUND C-reactive protein (CRP)- and leukocyte levels are common parameters to evaluate the inflammatory response after orthopaedic surgery and rule out infectious complications. Nevertheless, both parameters are vulnerable to disturbing biases and therefore leave room for interpretation. OBJECTIVE Since blood groups are repeatedly discussed to influence inflammatory response, our aim was to observe their impact on CRP and leukocyte levels after total hip and knee arthroplasty (THA/TKA). METHODS Short term postoperative CRP and leukocyte levels of 987 patients, who received either primary TKH (n= 479) or THA (n= 508), were retrospectively correlated with their blood group. ABO, Rhesus and a combination of both blood groups were differentiated. RESULTS CRP levels after TKA were significantly higher in blood type AB than in type A and O on day 2-4 and also than in type A on day 6-8. Leukocyte levels after THA were significantly higher in blood group type O than in type A on day 6-8 while still remaining in an apathological range. We observed no significant differences between Rhesus types and Rhesus types and CRP or leukocyte levels. CONCLUSION We observed significantly increased CRP levels after TKA in patients with blood group AB. Since the elevated CRP levels do not account for early periprosthetic infection, surgeons should include this variation in their postoperative evaluation.

Abstract
Liver transplantation is a critical procedure for patients with end-stage liver disease, but it is often hindered by ABO-incompatibility between the donor and recipient, which can lead to immediate humoral rejection. We present a unique case involving a 10-month-old patient who, by accident, received an ABO-incompatible partial liver transplant from a type A mother without undergoing desensitization. Remarkably, during a 21-year follow-up period, the patient exhibited no signs of humoral or graft rejection, despite nonadherence to medication. This case highlights the possibility of dual tolerance in pediatric ABO-incompatible liver transplantation and provides insights into immune tolerance mechanisms, with implications for enhancing patient care and reducing healthcare costs. Further research is necessary to clarify these mechanisms and to evaluate the long-term durability of tolerance in pediatric transplant recipients.

Abstract
OBJECTIVE To determine the association between the ABO blood group and preeclampsia. METHODS This is a case-control study that included patients with (n = 253) and without (n = 457) preeclampsia/eclampsia in Northeastern Mexico. Data were obtained from electronic medical records. Binary multiple logistic regression analysis was used for analyzing the association between the ABO blood group and preeclampsia according to parity status while adjusting for potential confounders. RESULTS Blood groups A, B, and AB showed adjusted odds ratios of 0.6 (95%CI 0.3-1.0), 1.1 (95%CI 0.6-2.2), and 0.3 (95%CI 0.1-1.1) in multiparous women, respectively. No association was found in nulliparous women either. CONCLUSIONS ABO blood groups were not associated with preeclampsia in Mexican women. [Figure: see text].

Abstract
OBJECTIVES This study evaluated the relationship between acquired cataract's different types and the ABO and Rh blood classes. METHODS Overall, 520 patients, by randomized sampling method, participated in this retrospective cross-sectional study. After reviewing the patient's medical records and laboratory results, the patient's demographics, ABO group, Rh, and cataract type were documented. RESULTS A total of 520 patients were included in the research, with a mean age of 67.57 ± 11.85. Most of them were female (n = 286, 55%). Mix (n = 230, 44%) and nuclear sclerotic (NS) (n = 167, 32%) cataracts were the most common types. The posterior subcapsular cataract (PSC) prevalence in females was significantly higher than in males (16.1% vs.7.3% p = 0.002). Also, men had more NS cataracts than females (89, 38% vs. 78, 27.3%) (p = 0.009). Patients with PSC were significantly younger than others (all p-values < 0.001). Our results showed that cataract types are independent of blood group types and Rh (P > 0.05). CONCLUSION Although our findings showed that cataract types are independent of blood group types and Rh, they can be compared with future studies on the association of other Blood-Group Systems in developing acquired cataracts.

Abstract
Background Pretransplant therapies such as rituximab and plasmapheresis have led to an increase in ABO-incompatible (ABOi) living donor liver transplantation (LDLT), thus helping to overcome organ shortages. This study evaluated the changes in anti-A/B titers and CD19 levels over time in patients undergoing ABOi LT and aimed to understand the effect of single-nucleotide polymorphisms (SNPs) in Fc gamma receptor (FcγR) on rituximab therapy. Methods Two SNPs of FCGR2A (131H/R) and FCGR3A (158F/V) were identified. The clinical data on 44 patients who underwent ABOi LDLT between May 2019 and October 2021 at Seoul National University Hospital were reviewed retrospectively. Results Following desensitization with rituximab and subsequent LDLT, the anti-A/B titer recovered within 1 week, but decreased thereafter. The CD19 level increased at 3 months after LT. The genotyping data for FCGR3A (158F/V) indicated that two patients had the V/V genotype, and 42 had the F/V genotype. In the genotyping data for FCGR2A (131H/R), 21 patients had the H/H genotype, three had the R/R genotype, and 20 had the H/R genotype. However, there were no significant differences in anti-A/B and CD19 levels, bacteremia rates, T cell-mediated rejection, antibody-mediated rejection, or the survival rate among the FCGR2A types. Conclusions There were significant changes in the anti-A/B titers and CD19 levels over time in each patient after ABOi LDLT. The difference in outcomes following LT according to the FcγR SNP type for rituximab was unclear. Further studies with larger sample sizes are needed to confirm the effect of FcγR SNPs on rituximab therapy.

Abstract
BACKGROUND Acute myeloid leukemia (AML) is one of the most common types of leukemia in adults. However, AML is relatively rare in the population overall, accounting for only about 1 percent of all cancers. Treatment for AML can be very effective for some patients, yet it leaves others with serious and even life-threatening side effects. Chemotherapy is still the primary treatment for most AML, but over time, leukemia cells become resistant to chemotherapy drugs. In addition, stem cell transplantation, targeted therapy, and immunotherapy are currently available. At the same time, with the progression of the disease, the patient may have corresponding complications, such as coagulation dysfunction, anemia, granulocytopenia, and repeated infection, so transfusion supportive therapy will be involved in the overall treatment regime. To date, few articles have reported on blood transfusion treatment options for patients with ABO subtypes AML-M2. Blood transfusion therapy is an important supportive treatment for AML-M2, and accurate determination of patients' blood type is one of the most important steps in the treatment process. In this study, we explored blood typing and supportive treatment strategies for a patient with A2 subtype AML-M2 to provide the basis for treatment for all patients.
CASE SUMMARY In order to determine the blood type of the patient, serological and molecular biological methods were used for reference tests, and the genetic background was studied to determine the patient's final blood type and select the appropriate blood products for infusion treatment. According to the results obtained by serological and molecular biological methods, the blood type of the patient was A2 subtype; the genotype was A02/001; the irregular antibody screening was negative, and anti-A1 was found in the plasma. According to the overall treatment plan, active anti-infection, elevated cells, component blood transfusion support, and other rescue and supportive treatments were given, and the patient successfully passed the stage of myelosuppression after chemotherapy. Re-examination of bone marrow smears showed that AL was in complete remission of bone marrow signs, and minimal residual leukemia lesions suggested no cells with obvious abnormal immunophenotype (residual leukemia cells < 10-4).
CONCLUSION The infusion of patients with A2 subtype AML-M2 with A irradiated platelets and O washing red blood cells can meet the needs of clinical treatment.

Abstract
Background: Breast cancer and cervix cancer are the prevalent and deadly types of solid tumors around the world. According to the importance of cancer, it is necessary to understand predisposing factors that affect cancer risk. In this regard, previous studies suggest that blood types particularly ABO and Rh-Hr Blood-Group System could play roles in the risk and different features of cancers. In the present study, we aimed to evaluate the potential of ABO and Rh blood groups as risk factors for breast cancer and cervix cancer. Materials and Methods: A retrospective study included 109 and 14 patients diagnosed with breast cancer and cervix cancer, respectively with known ABO and Rh blood types, between 2018 and 2020 in Khuzestan province, Iran. For compression of ABO blood groups distribution between the cancer patients group and the healthy population, we used data from a large-scale study that report the distribution of ABO blood groups in 29,922 blood donors in Khuzestan province. Results: Based on obtained results the most frequent blood group is O followed by B, A, and AB in breast cancer and followed by A, B, and AB in cervix cancer. Results showed no significant association between ABO and Rh and the risk of breast and cervix cancer. Moreover, there is no relationship between blood types and clinic pathological features of breast cancer. Conclusion: Based on our data, ABO and in this regard, previous studies suggest that blood types particularly ABO and Rh-Hr Blood-Group System could play roles in the risk and different features of cancers. In the present study, we aimed to evaluate the potential of ABO and Rh blood groups as risk factors for breast cancer and cervix cancer do have not any association with the risk of breast and cervix cancer and their characteristics.

Abstract
Objective To evaluate the safety and clinical efficacy of ABO-incompatible living-donor liver transplantation (LDLT) in children. Methods The clinical data of 62 children who underwent for the first time living donor liver transplantation in our hospital from April 2019 to July 2020 were retrospectively analyzed. According to the blood type matching of donor and recipient, the patients were divided into 3 groups, ABO-identical (ABO-Id, n=33), ABO-compatible (ABO-C, n=10) and ABO-incompatible (ABO-In, n=19), the median age of recipients in the three groups being 5 months. In the ABO-In group, 4 recipients whose condition was combined with liver failure and 2 recipients who had blood group antibody titers≥1∶32 received preoperative plasma exchange. All ABO-incompatible recipients had preoperative blood group antibody titers<1∶32. All recipients in the three groups underwent piggyback liver transplantation and received immunosuppressive and anticoagulation therapy. Postoperative follow-up was 5 to 20 months, the median being 12 months, measured until December 31, 2020 or until the date of death. Baseline clinical data, postoperative survival, and postoperative complications of recipients in the three groups were analyzed. Results There were no significant differences in age, gender, underlying disease, operation history, Child Pugh score, donor age, graft to recipient weight ratio (GR/WR), cold ischemia time, warm ischemia time, duration of surgery, intraoperative blood loss and the use of immunosuppressants among the recipients in the three groups (all P>0.05). There was one death in the perioperative period and two deaths in the postoperative period in the ABO-Id group. There was one death in the postoperative period in the ABO-C group. There was one death in the perioperative period and one death in the postoperative period in the ABO-In group. There was no significant difference in the overall cumulative survival rate among the three groups ( P>0.05). There were no significant differences in the incidence of postoperative infection, acute rejection, biliary anastomotic stenosis and vascular complications among the three groups ( P>0.05). Conclusion ABO-In LDLT is an effective and safe treatment option that can effectively expand the pool of live donors for liver transplantation and save the life of children with end-stage liver disease.

Abstract
PURPOSE Although multiple mechanisms associated with Peyronie's disease (PD) have been proposed, details regarding etiologic factors, especially genetic, remain unclear. We examined the relationship of the ABO blood type system, known as a genetic factor associated with susceptibility to a number of diseases, with PD in Japanese males. MATERIALS AND METHODS We compared 202 Japanese PD patients treated with surgery at our hospital between March 2004 and December 2019 with 846 randomly selected non-PD male patients who underwent urological surgery during the same period regarding distribution of ABO blood types. In addition, we assessed the risk of PD according to blood type group among all study participants using odds ratio (OR) and 95% confidence interval (CI) calculations. RESULTS The distribution of individual blood types in the control group was nearly the same as that in the general Japanese population. In contrast, O, A, B, and AB blood types were noted in 37.6%, 36.1%, 14.9% and 11.4%, respectively, of the PD patients, which was significantly different from the control group, where blood type O was found in 29.1% and B in 23.2% (p<0.05). Our results showed that as compared with patients with blood group B, those with another blood type were more likely to develop PD, among which type O had a significantly increased OR of 2.018 (CI, 1.271-3.205). CONCLUSIONS These are the first reported results showing that ABO blood type may be associated with risk of PD, though further investigations are needed.

Abstract
It is unknown whether moderate thrombocytopenia represents a risk factor for post‐partum haemorrhage (PPH). We assessed PPH risk among women with a platelet count of between 100 and 50 × 109/l and stratified the risk for O/non‐O blood group. We included consecutive women undergoing vaginal delivery or caesarean section with moderate thrombocytopenia. Women with >150 × 109/l platelets at delivery were selected as controls and matched for age, type of birth and ethnicity. Odds ratios (ORs) with their 95% confidence intervals (95% CIs) were calculated as risk estimates. A total of 94 thrombocytopenic women and 94 controls were included in the study. The rate of PPH was significantly higher in thrombocytopenic women than in controls (37% vs. 10%, p < 0.001); there was a higher risk of PPH in the thrombocytopenic group when compared to the control group (adjusted OR 4.7, 95% CI 2.1–10.8, p < 0.01) and this association was stronger in blood group O carriers (adjusted OR 11.0, 95% CI 2.4–49.6, p < 0.01). In conclusion, our study shows that a moderate thrombocytopenia is a risk factor for PPH, especially in blood group O carriers.

Abstract
Critical antibody titers have been described as factors associated with hemolysis in ABO plasma-incompatible platelet (PLT) transfusions. This study was carried out to describe the frequency of high-titers anti-A and antiB IgM and IgG antibodies in group O apheresis platelet donors, and to explore differences according to the donor characteristics. A cross-sectional study was carried out at the Blood Bank of a National Hospital in Peru from January to March 2019. IgM and IgG antibodies against A1 and B antigens were quantified in 339 platelet donors using the direct hemagglutination technique and the solid-phase adherence technique, respectively. For analysis purposes, two cut-off points; ≥128 and ≥64, were used to define a critical titer for IgM due to a lack of consensus. An IgG titer of ≥256 was also defined as critical. Of the donors, 22.1 % had critical IgM titers when the cut-off point was defined as ≥128. However, when the IgM cut-off was ≥64, the frequency of platelet donors with critical titers increased to 54.0 %. The frequency of donors with critical IgG titers was 23.5 %. Higher IgG titers were associated with female donors while higher IgM titers were negative associated with age. One in two or three platelet donors, depending on the cutoff point used to define a critical IgM titer, had at least one critical titer of anti-A or anti-B antibodies. Early identification of platelet donors with critical antibody titers could prevent passive transfusion of ABO antibodies to non-isogroup recipients.

Abstract
Introduction ABO blood group antigens within grafts are continuously exposed to anti-A/B antibodies in the serum of recipients after ABO-incompatible (ABOi) kidney transplantation and are instrumental in antibody-mediated rejection. Some individuals secrete soluble blood group antigens into body fluids. In this study, we investigated the effect of donor and recipient secretor status on the outcomes of ABOi kidney transplantation. Methods Data of a total of 32 patients with ABOi living donor kidney transplantation were retrospectively collected between 2014 and 2020 in West China Hospital. The genotype and phenotype of both donors and recipients were examined and evaluated with post-transplantation anti-A/B titer changes, graft function, and rejection. Results Of the 32 recipients and 32 donors, 23 (71.9%) recipients and 27 (84.4%) donors had secretor genotypes, whereas 9 (28.1%) recipients and 5 (15.6%) donors did not. Anti-A/B titers after ABOi kidney transplantation were not significantly influenced by the secretor status of either donors or recipients. The post-transplantation serum creatinine (Scr) levels and estimated glomerular filtration rate (eGFR) was better in weak- or non-secretor recipients at day 30 (Scr P = 0.047, eGFR P = 0.008), day 90 (Scr P = 0.010, eGFR P = 0.005), and month 9 (eGFR P = 0.008), and recipients from secretor donors had a lower incidence of graft rejection in the first year after ABOi transplantation (P = 0.004). Conclusions A weak secretor status phenotype was found in both genotypes, i.e., individuals who secreted soluble antigens as well as those who did not. The recipient ABH-secretor status may have an influence on early posttransplant renal function, and the donor ABH-secretor status might affect the incidence of graft rejection.

Abstract
PURPOSE The objective of this cross-sectional study was to evaluate the relationship between ABO blood groups and periodontal diseases. MATERIALS AND METHODS Four hundred sixteen subjects (223 females, 193 males) were recruited according to the eligibility criteria. Periodontal examination was performed, including full-mouth plaque index (PI), bleeding on probing (BOP), clinical attachment level (CAL), and interproximal bone loss (IBL). ABO blood group patterns were determined based on self-reports, confirmed by medical records. The chi-squared test was done to evaluate the data (p < 0.05). RESULTS Out of the 416 subjects, 52.2% were blood group O, whereas 27.8% were blood group A. 46.8% of patients with blood group O had gingivitis and 49.6% had periodontitis. 31.2% of patients with blood group A had gingivitis,while 29.5% had periodontitis. The blood group with the lowest percentage among patients with gingivitis was AB, with a rate of 6.2%; in this blood group, 8.1% had periodontitis. CONCLUSIONS There is no association between periodontal diseases and ABO blood group types.

Abstract
For ABO-incompatible liver transplantation (ABO-i LT), therapeutic plasma exchange (TPE) is performed preoperatively to reduce the isoagglutinin titer of anti-ABO blood type antibodies. We evaluated whether perioperative high isoagglutinin titer is associated with postoperative risk of acute kidney injury (AKI). In 130 cases of ABO-i LT, we collected immunoglobulin (Ig) G and Ig M isoagglutinin titers of baseline, pre-LT, and postoperative peak values. These values were compared between the patients with and without postoperative AKI. Multivariable logistic regression analysis was used to evaluate the association between perioperative isoagglutinin titers and postoperative AKI. Clinical and graft-related outcomes were compared between high and low baseline and postoperative peak isoagglutinin groups. The incidence of AKI was 42.3%. Preoperative baseline and postoperative peak isoagglutinin titers of both Ig M and Ig G were significantly higher in the patients with AKI than those without AKI. Multivariable logistic regression analysis showed that preoperative baseline and postoperative peak Ig M isoagglutinin titers were significantly associated with the risk of AKI (baseline: odds ratio 1.06, 95% confidence interval 1.02 to 1.09; postoperative peak: odds ratio 1.08, 95% confidence interval 1.04 to 1.13). Cubic spline function curves show a positive relationship between the baseline and postoperative peak isoagglutinin titers and the risk of AKI. Clinical outcomes other than AKI were not significantly different according to the baseline and postoperative peak isoagglutinin titers. Preoperative high initial and postoperative peak Ig M isoagglutinin titers were significantly associated with the development of AKI. As the causal relationship between high isoagglutinin titers and risk of AKI is unclear, the high baseline and postoperative isoagglutinin titers could be used simply as a warning sign for the risk of AKI after liver transplantation.

Abstract
BACKGROUND Factor VIII (FVIII) pharmacokinetics (PK) in adult hemophilia A populations are highly variable and have been previously determined to be influenced by von Willebrand factor:antigen (VWF:Ag), ABO blood group, and age. However, additional genetic determinants of FVIII PK are largely unknown. OBJECTIVES The contribution of VWF clearance, VWF-FVIII-binding activity, and genetic variants in VWF clearance receptors to FVIII PK in adult patients were assessed. METHODS FVIII PK assessment was performed in 44 adult subjects (age 18-61 years) with moderate or severe hemophilia A. VWF:Ag, VWF propeptide (VWFpp), VWFpp/VWF:Ag, and VWF:FVIII binding activity were measured. The VWF modifying loci CLEC4M, SCARA5, STAB2, and ABO, and the D'D3 FVIII-binding region of the VWF gene were genotyped. RESULTS VWF:Ag, VWFpp, and VWF:FVIIIB positively correlated with FVIII half-life and negatively correlated with FVIII clearance. VWFpp/VWF:Ag negatively correlated with FVIII half-life and positively correlated with FVIII clearance. The correlation between VWFpp/VWF:Ag and FVIII half-life was stronger for type non-O patients than for type O patients, suggesting that slower VWF clearance increases FVIII half-life. Patients heterozygous for the CLEC4M rs868875 variant had increased FVIII clearance when compared with individuals homozygous for the reference allele. The CLEC4M variable number of tandem repeat (VNTR) alleles were also associated with the rate of FVIII clearance. When compared with the quartile of patients with the fastest FVIII clearance, the quartile of patients with the slowest FVIII clearance had a decreased frequency of the CLEC4M 5-VNTR. CONCLUSIONS VWF-FVIII binding activity and genetic determinants of VWF clearance are important contributors to FVIII pharmacokinetics in adult patients.

Abstract
BACKGROUND There are no contemporary published data on the frequency of the ABO and Rhesus D (RhD) blood groups in the Northern Territory (NT) of Australia, particularly for the large Aboriginal population. AIMS To establish the frequencies of ABO and RhD blood groups in the NT Aboriginal and non-Aboriginal populations in order to aid transfusion inventory management and clinical practice. METHODS Retrospective data were collected from 1 January 2012 to 31 December 2012. All patients with a blood group sample processed by the NT public hospital laboratories and a recorded ABO and RhD report were included. Results were analysed using Stata 14. RESULTS The Aboriginal and non-Aboriginal populations had significantly different ABO and RhD distributions (P < 0.001). For Aboriginal individuals, 955/1686 (56.6%) were group O and 669/1686 (39.7%) were group A. In non-Aboriginal individuals, 1201/2657 (45.2%) were group O and 986/2657 (37.1%) were group A. We found that 1646/1686 (97.6%) of Aboriginal individuals were RhD positive, compared with 2225/2657 (83.7%) of non-Aboriginal individuals. Only 62/1686 (3.7%) of Aboriginal individuals were group B or AB, compared with 470/2657 (17.7%) of non-Aboriginal individuals. In Aboriginal individuals we found that group O was more common than A in the 'Northern' NT, whereas there was similar distribution of the groups in 'Central Australia'. CONCLUSIONS We found a significant difference in ABO and RhD blood groups between Aboriginal and non-Aboriginal individuals in the NT (P < 0.001). These findings will aid transfusion inventory management, allowing us to plan supply of blood products and reduce waste.

Abstract
Objective: To explore the application and discovery of genotyping, gene sequencing, and gene expression analysis in the determination of ABO blood group subtypes and antigen expression abnormalities in hematological malignancies patients. Methods: From June 2019 to May 2020, three clinical cases were found with forward and reverse ABO typing discrepancy or atypical serologic agglutination pattern in the laboratory and blood transfusion department of Hebei Yanda Ludaopei Hospital were selected. Sequence-specific primer PCR (PCR-SSP) and Sanger sequencing of ABO gene coding regions were performed to determine the ABO genotypes, and whole transcriptome sequencing was used to analyze ABO and FUT1 gene expression levels. Results: A 12-year-old female acute lymphoblastic leukemia patient was determined as O.01.02 and BA.04 sub-genotype, corresponding to the serological B(A) subtype, and her ABO gene expression was normal (354.80). A 41-year-old female acute myeloid leukemia patient was determined as A1.02 and B.01 genotype, corresponding to the serological A(1)B phenotype, and her ABO gene expression was significantly reduced (45.70). A 42-year-old male with myelodysplastic syndrome and myelofibrosis was determined as A1.02 and A2.05 sub-genotype, corresponding to the serological A(1) and A(2) phenotype, respectively, and his ABO expression was negative. FUT1 expression was in the normal range in all three cases. The clinical blood product infusion strategy was formulated according to the genotype and the corresponding immunological subtype, and no significant transfusion-related adverse reactions occurred. Conclusion: Blood group sub-genotypes or aberrant gene expression can lead to ambiguities in serological blood group determination in hematological malignancies patients. ABO genotyping and gene expression analysis can help in this scenario and escort blood product infusion safety.

Abstract
BACKGROUND Data on the effect of ABO blood group (ABO), von Willebrand factor (VWF) levels, and age on factor VIII (FVIII) in non-severe haemophilia A (HA) is scarce. OBJECTIVE To investigate if ABO, VWF levels, and age have an influence on the variability of FVIII levels and consequently on the assessment of severity in non-severe HA. PATIENTS/METHODS Eighty-nine patients with non-severe HA and 82 healthy controls were included. Data on ABO was collected and FVIII clotting activity (FVIII:C) with one-stage clotting assay (FVIII:C OSA) and chromogenic substrate assay (FVIII:C CSA), FVIII antigen (FVIII:Ag) and VWF antigen (VWF:Ag) and activity (VWF:Act) were determined. RESULTS In HA, FVIII:C OSA and CSA and FVIII:Ag were not different between non-O (n = 42, median 15.5, interquartile range 10.4-24.0; 10.0, 6.8-26.0 and 15.2, 10.7-24.9) and O (n = 47, 14.1, 9.0-23.0; 10.0, 5.0-23.0 and 15.2, 9.3-35.5), whereas in healthy controls, non-O individuals had significantly higher FVIII levels. FVIII C showed no relevant correlation with VWF levels in HA, but we observed strong correlations in healthy controls. Age had only a minor influence in HA, but had a considerable impact on FVIII:C in healthy controls. In multivariable regression analysis ABO, VWF:Ag and age were not associated with FVIII:C in HA, whereas this model explained 61.3% of the FVIII:C variance in healthy controls. CONCLUSIONS We conclude that in non-severe HA ABO and VWF levels do not substantially influence the variability of FVIII levels and age has only minor effects on it, which is important information for diagnostic procedures.

Abstract
Objective To investigate the relationship between primary femoral head necrosis (ONFH) and an ABO blood group. Methods This study was a retrospective case–control trial. An analysis of the clinical data of an ABO blood group with 516 patients (case group) with ONFH and 489 limb‐fracture patients (control group) without previous hip pain was obtained from the Second Hospital of Shanxi Medical University from November 2015 to November 2018. The clinical data included gender, age, height, weight, a history of smoking, alcohol abuse, prior medical history, hormone use, and ABO blood type. A logistic regression model was used for univariate and multivariate analysis. Results From November 2015 to November 2018, there were 267 males and 249 females in the 516 cases of ONFH in the case group. The control group included 289 males and 200 females. In terms of age, the average age of the case group was significantly lower than that of the control group. In terms of body mass index (BMI), the BMI of the case group was significantly higher than that of the control group (P < 0.05). From the previous medical history of patients in the two groups (coronary heart disease, hypertension, cerebrovascular disease, diabetes, and peripheral vascular disease), there was no significant difference between the two groups from a statistical perspective (P < 0.05). However, according to the risk factors of ONFH (smoking, alcohol abuse, hyperlipidemia, and hormone‐use history), there were significant differences between the case group and the control group. There was no statistical difference in the quantitative distribution ratio of the four blood types – A, B, O, and AB – between the case group and the control group. The outcomes of logistic multiple regression analysis presented that there was no significant correlation between the occurrence of ONFH and blood type A, B, AB, and O (P > 0.05). However, there are significant differences in the disease progression between the different blood types. There was a significant difference in the progression of disease between type A and type O. Among them, patients with ONFH and type A blood had the fastest progression with an average of 2.318 years, and the slowest progression was found in type O blood with an average of 5.15 years. Conclusions The ABO blood group has no correlation with the occurrence of ONFH, but the ABO blood type is closely related to the disease progression of ONFH.

Abstract
Introduction Previous research has suggested that individuals with different blood groups show varied incidences of noise-induced hearing loss. The reduced otoacoustic emissions amplitudes indicate the higher possibilities of outer hair cell damage for noise exposure. Objective The objective is to analyze the characteristics of otoacoustic emissions, including the occurrence of spontaneous otoacoustic emission and the amplitudes of distortion product otoacoustic emission at certain frequencies in full term neonates with different ABO blood groups. Methods A total of 80 selected full-term female neonates who passed the initial newborn hearing screen were enrolled into the study, with equal number of participants in four ABO blood groups (Blood Group A, Blood Group B, Blood Group AB, Blood Group O). Measurements of spontaneous otoacoustic emission and distortion product otoacoustic emission were performed in both ears for all participants. Results (1) The blood group O participants showed significantly fewer spontaneous otoacoustic emission occurrences than the other three blood groups (A = 70%, B = 80%, AB = 67%, O = 25%, p < 0.05). (2) The blood group O participants showed lower DPOAE amplitudes at 1257 Hz (M = 4.55 dB, SD = 8.36), 1587 Hz (M = 11.60 dB, SD = 6.57), 3174 Hz (M = 7.25 dB, SD = 5.99), 5042 Hz (M = 13.60, SD = 6.70) than participants with the other three blood groups in left ears (p < 0.05). In right ears, the blood group O participants showed reduced amplitudes at 1257 Hz (M = 6.55 dB, SD = 8.36), 1587 Hz (M = 13.60 dB, SD = 6.57), 3174 Hz (M = 7.65 dB, SD = 6.43), 5042 Hz (M = 13.65 dB, SD = 6.50) than participants from non-O blood groups (p < 0.05). Conclusion Female individuals with blood group O have lower otoacoustic emissions values than individuals with the other three blood groups. We need to further investigate the possible relationships between ABO blood group and cochlear function, including the potential influences of noise damage on cochlear outer hair cells.

Abstract
Various cells from humans and animals have been established as cell lines, and their features, characteristics, and origins have been reported. Many laboratories use cell lines as model cells, which are selected to suit research purposes. We attempted to identify the ABO genotypes of 31 human leukemia and lymphoma cell lines stored in our laboratory using three methods: the PCR amplification of specific alleles (PASA), PCR-restriction fragment length polymorphism (RFLP), and the direct DNA sequencing of PCR products. We distinguished 31 human leukemia and lymphoma cell lines examined into six major ABO genotypes: A/O (A101/O01: n = 1, A101/O12: n = 4, A101/O26: n = 1, A101/O49: n = 1, A102/O01: n = 3), A/A (A101/A101: n = 1, A102/A102: n = 2), B/O (Bw29/O01: n = 1), B/B (B101/B101: n = 2), O/O (O01/O01: n = 9, O01/O02: n = 1, O01/O26: n = 1, O02/O03: n = 1), and A/B (A102/B101: n = 3). To the best of our knowledge, this is the first study to identify the ABO genotypes of various cell lines. The ABO genotypes of cell lines are important when selecting an experimental model cell for an ABO blood group study, and are essential information for cell lines. These results may be employed by research and clinical laboratories as well as in the forensic field.

Abstract
(1) Background: In a previous study, we found that two phenotypes related to platelet reactivity, measured with the PFA-100 system, were highly heritable. The aim of the present study was to identify genetic determinants that influence the variability of these phenotypes: closure time of collagen-ADP (Col-ADP) and of collagen-epinephrine (Col-Epi). (2) Methods: As part of the GAIT-2 (Genetic Analysis of Idiopathic Thrombophilia (2) Project, 935 individuals from 35 large Spanish families were studied. A genome-wide association study (GWAS) with ≈ 10 M single nucleotide polymorphisms (SNPs) was carried out with Col-ADP and Col-Epi phenotypes. (3) Results: The study yielded significant genetic signals that mapped to the ABO locus. After adjusting both phenotypes for the ABO genotype, these signals disappeared. After adjusting for von Willebrand factor (VWF) or for coagulation factor VIII (FVIII), the significant signals disappeared totally for Col-Epi phenotype but only partially for Col-ADP phenotype. (4) Conclusion: Our results suggest that the ABO locus exerts the main genetic influence on PFA-100 phenotypes. However, while the effect of the ABO locus on Col-Epi phenotype is mediated through VWF and/or FVIII, the effect of the ABO locus on Col-ADP phenotype is partly produced through VWF and/or FVIII, and partly through other mechanisms.

Abstract
Background: The associations between ABO blood type and risk of diseases including cancer have been reported
from epidemiological studies. Self-reporting is one of the most widely used methods of collecting the ABO blood type
information. Verifying the accuracy of self-reporting is important to consider measurement errors. We aimed to conduct
validation of self-reported ABO blood types in the Japan Nurses’ Health Study (JNHS), which is a large prospective
cohort study. Methods: The concordance rate between self-reported and serologically or genetically inferred ABO
blood groups was investigated for a subsample of 41 subjects from the Gunma Nurses’ Health Study, which was a pilot
cohort study that preceded the JNHS. The presence of antibodies to A or B antigens in serum (serological test) and
allele types of the ABO gene (genotyping test) were determined by using frozen blood samples that were preserved
for approximately 7 years. ABO blood types were determined from these tests and compared with self-reported data.
Results: All of the nurses reported that their ABO blood groups were concordant with those determined by a serological
and/or genotyping test. Self-reported ABO blood types of 35 of 38 (92.1%) participants were consistent with the results
from serological typing, while the answers of three participants were not. In these three participants, ABO genotypes
that were inferred from genotyping of three single nucleotide polymorphisms in ABO loci perfectly matched with their
self-reported ABO types, and all of these were O-type. Conclusions: Japanese health professionals report their blood
type with a high degree of accuracy. Special attention should be paid to the O-type group in serological analysis of
blood samples that have been preserved for several years in longitudinal studies.

Abstract
BACKGROUND Genome-wide association studies of patients with coronary artery disease (CAD) suggest that several risk loci increase the risk of CAD and myocardial infarction (MI) equally. In contrast, the ABO locus is stronger associated with MI than with CAD, but the underlying mechanisms are unknown. PURPOSE To investigate the association between the ABO risk variant and platelet activation and aggregation. Moreover, to explore the effects of other CAD-associated risk variants. METHODS We included 879 stable CAD patients receiving low-dose aspirin. All patients were genotyped for 45 genome-wide significant CAD risk variants, including rs495828 at the ABO locus. A genetic risk score (GRS) was calculated to assess the combined risk of all genetic variants. Serum soluble P-selectin (sP-selectin) and thromboxane B2 were used as measures of platelet activation, and platelet aggregation was assessed by multiple electrode aggregometry (MEA) using arachidonic acid and collagen as agonists and VerifyNow. RESULTS The rs495828 CAD risk allele was associated with higher MEA platelet aggregation; arachidonic acid: 14.9% (6.7-23.7%, p = 0.0002) higher AUC (Area Under aggregation Curve) per risk allele, and collagen: 13.1% (5.8%-20.9%, p = 0.0003). Conversely, sP-selectin levels were 7.5% (3.1%-11.7%, p = 0.001) lower per risk allele. Rs495828 genotypes were not associated with aggregation assessed by VerifyNow (p = 0.30) or S-thromboxane B2 levels (p = 0.98). None of the remaining variants or the GRS were associated with platelet activation or aggregation. CONCLUSIONS The ABO risk allele was associated with increased platelet aggregation as assessed by MEA. This finding may contribute to explain the increased MI risk in ABO risk variant carriers.

Abstract
Schistosomiasis or bilharzia is a widespread parasitic disease caused by blood flukes of the genus Schistosoma. Some factors have been investigated previously regarding their effect on the pathophysiological mechanism of human schistosomiasis, but the possible influence of the ABO blood group on the severity of Schistosoma infection has been the most promising. Hence, we performed a systematic review and meta-analysis to further investigate the association of the ABO blood group with schistosomiasis susceptibility. Selected publications were retrieved from PubMed up to 21 August 2018, for related studies written in English. Number of cases (with schistosomiasis) and controls (without schistosomiasis) were extracted across all ABO blood types. Odds ratios (OR) and 95% confidence intervals (CI) were computed, pooled and interpreted. Subgroup analysis by the species of Schistosoma infecting the population and the participants' ethnicity was also performed. The overall analysis revealed heterogeneity in the outcomes, which warranted the identification of the cause using the Galbraith plot. Post-outlier outcomes of the pooled ORs show that individuals who are not blood type O are more susceptible (OR: 1.40; 95% CI: 1.17-1.67; PA < 0.001) to schistosomiasis than those who are blood type O (OR: 0.71; 95% CI: 0.60-0.85; PA < 0.001). Subgroup analysis yielded the same observations regardless of the species of schistosome and the ethnicity of the participants. Results of this meta-analysis suggest that individuals who are blood type B and A are more susceptible to schistosomiasis than those who are blood type O. However, more studies are needed to confirm our claims.

Abstract
OBJECTIVE To determine overall long-term patient and graft survival rates among the recipients liver transplanted due to acute liver failure (ALF). Secondary aims included assessment of whether diagnosis, donor-recipient blood group compatibility and time-era of transplantation affected the outcome, and whether prescription-free availability of acetaminophen increased the need for liver transplantation (LTx). MATERIALS AND METHODS A Retrospective cohort study of 78 patients who underwent LTx for ALF at Karolinska University Hospital 1984-2014. Patients were divided into two cohorts according to two 15-year periods: early cohort transplanted 1984-1999 (n = 40) and late cohort transplanted 2000-2014 (n = 38). Survival rates were established using Kaplan-Meier analyses. RESULTS ALF patient survival rates for 1-year, 5-years, 10-years and 20-years were 71%, 63%, 52% and 40%, respectively. Survival for the late cohort at 1, 5 and 10 years was 82%, 76% and 71%, respectively. A high early mortality rate was noted during the first three months after transplantation when compared to LTx patients with chronic disease. Long-term survival rates were comparable between patients with ALF and chronic liver disease. Prescription-free access to acetaminophen did not increase the need for LTx. There was a strong trend towards improved survival in blood group identical donor-recipient pairs and blood group O recipients may have benefitted from this. CONCLUSIONS The high early mortality rate most likely reflects the critical pre-transplant condition in these patients and the urgent need to sometimes accept a marginal donor liver. Long-term survival improved significantly over time and variation in patient access to acetaminophen did not influence the rate of LTx in our region.

Abstract
Chronic kidney disease (CKD) affects 30 million Americans and is associated with approximately a two-fold increased risk of venous thromboembolism (VTE). There is a graded increased risk of VTE across declining kidney function, as measured by estimated glomerular filtration rate (eGFR) and albuminuria. When patients with end-stage kidney disease (ESKD) experience VTE they are more likely than the general population to be hospitalized and they have a higher mortality. The incidence and consequences of VTE may also differ depending on the cause of kidney disease. In addition, kidney transplant patients with VTE are at a greater risk for death and graft loss than transplant patients without VTE. The reasons that patients with CKD are at increased risk of VTE are not well understood, but recent data suggest that factor VIII is a mediator. Factor VIII is an essential cofactor in the coagulation cascade and a strong risk factor for VTE in general. It is inversely correlated with eGFR and prospective studies demonstrate that factor VIII activity predicts incident CKD and rapid eGFR decline. The etiology of CKD may also influence factor VIII levels. This review summarizes the epidemiology VTE in CKD and reviews the biochemistry of factor VIII and determinants of its levels, including von Willebrand factor and ABO blood group. We explore mechanisms by which the complications of CKD might give rise to higher factor VIII and suggests future research directions to understand how factor VIII and CKD are linked.

Abstract
Objective: To explore the normal range of plasma VWF levels of healthy Chinese and to analyze the influencing factors to VWF level. Methods: To detect the levels of von Willebrand factor antigen (VWF∶Ag) , von Willebrand factor ristocetin cofactor activity (VWF∶Rco) , von Willebrand factor collagen binding activity (VWF∶CB) , and the factor Ⅷ coagulation activity (FⅧ∶C) by using fully automatic and standardized testing instruments and matching reagent in 70 healthy Chinese. The effects of age, ABO blood type, gender and region were also analyzed. Meanwhile, 8 standard plasma samples (2 normal subjects, 6 cases of type 2 VWD) confirmed by NIBSC were tested for VWF values. Results: ① In 70 cases of healthy Chinese, the mean value of plasma VWF∶Ag, VWF∶Rco and VWF∶CB were (95.4±44.9) %, (105.9±35.4) % and (89.8±28.4) %, respectively; the ratio of VWF∶Rco/VWF∶Ag and VWF∶CB/VWF∶Ag was 1.18±0.25 and 1.03±0.29, respectively. ②There was no statistical significance in plasma VWF values between the age ≥30 years and <30 years group (P>0.05) . ③The VWF∶Rco, VWF∶CB of type O blood group were lower than that of non-O group (t=2.074, P=0.042; t=3.949, P=0.001) , but there was no statistical significance in VWF∶Ag, VWF∶Rco/VWF∶Ag, VWF∶CB/VWF∶Ag between the two groups (P>0.05) . ④There was no significant difference in VWF values between male and female groups (P>0.05) . ⑤The VWF∶Ag, VWF∶CB of the northern population (North area of Huaihe River) group were higher than that of southern population (Suzhou area) group (t=4.525, P=0.001; t=3.214, P=0.002) , but VWF∶Rco/VWF∶Ag, VWF∶CB/VWF∶Ag were lower than that of southern population group (t=6.373, P=0.001; t=2.902, P=0.005) , and there was no significant difference in VWF∶Rco between the two groups (t=1.598, P=0.115) . ⑥The VWF values of 8 standard plasma samples were in accordance with the known diagnosis. Conclusions: A more integrate plasma VWF levels of healthy Chinese people were obtained for the first time by using fully automatic and standardized testing instruments. It was also found that ABO blood group and region had a significant impact on the level of VWF, while the age and gender had no significant effect.

Abstract
PURPOSE Several studies have evaluated the association between ABO blood group and the prognosis of various types of cancer; however, little is known about the relationship between ABO blood group and esophageal squamous cell carcinoma (SCC). We investigated how ABO blood group and clinicopathological characteristics are related to the survival of Japanese patients with esophageal SCC. METHODS We reviewed the medical records of 181 patients who underwent surgery for esophageal SCC between June, 2004 and December, 2015 and analyzed the association between ABO blood group and clinicopathological factors. Clinicopathological factors were also evaluated by univariate and multivariate analyses for possible association with survival. RESULTS The prevalence of each blood group was as follows: A, 35.5%; B, 22.4%; O, 32.8%; and AB, 8.2%. The 5-year overall survival of all patients was 37.1%. Patients with non-type B blood had significantly worse 5-year overall survival than those with type B blood (30.2 vs. 58.8%, P < 0.05). CONCLUSIONS ABO blood groups were associated with the survival of Japanese patients with esophageal SCC. Patients with non-B blood groups had significantly worse overall survival than those with the B blood group.

Abstract
Background 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. Methods 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. Results 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. Conclusion The study has a significant implication on the management of blood bank and transfusion services in Saudi Arabian patients.

Abstract
UNLABELLED Essentials Risk of venous thrombosis (VT) related to common genetic variants in those aged 70+ is unknown. We studied Factor V Leiden, prothrombin mutation, non-O blood group and family history (FH) of VT. Risk of VT was increased 2.2-, 1.4-, 1.3- and 2.1-fold respectively. FH is easy to obtain and can be implemented in clinical decision rules of VT risk in the elderly. Click to hear Prof. Reitsma discuss genetic risk factors of arterial and venous thrombosis SUMMARY Background As the incidence of venous thrombosis (VT) increases steeply with age and the number of elderly people is on the rise, studies of VT in this age group are important. Objectives We aimed to study the associations of common genetic risk factors (i.e. the factor V Leiden and prothrombin G20210A mutations, non-O blood group and family history of VT) with risk of a first VT in older age (> 70 years). Methods Four hundred and one consecutive cases with a first-time thrombosis and 431 controls (all ≥ 70 years) were included in the AT-AGE case-control study. Information on risk factors for VT, including family history of VT in first-degree relatives, was obtained by interview. Unprovoked VT was defined as thrombosis not related to surgery, fracture, plaster cast or immobility within 3 months prior to VT. Results The risk of VT was 2.2-fold increased in factor V Leiden carriers (95% confidence interval [CI], 1.2-3.9), 1.4-fold increased in prothrombin mutation carriers (95% CI, 0.5-3.9), and 1.3-fold increased in those with non-O blood group (95% CI, 1.0-1.8). Positive family history of VT was associated with a 2.1-fold increased risk of VT (95% CI, 1.5-3.1). The highest risk of VT was found in individuals who had both a positive family history and were carriers of one of the two prothrombotic mutations. Conclusions Genetic factors clearly related to VT in younger populations were also risk factors in older age and a positive family history was also important in this age group.

Abstract
BACKGROUND ABO blood groups have been shown to be associated with increased risks of venous thromboembolic and arterial disease. However, the reported magnitude of this association is inconsistent and is based on evidence from small-scale studies. METHODS AND RESULTS We used the SCANDAT2 (Scandinavian Donations and Transfusions) database of blood donors linked with other nationwide health data registers to investigate the association between ABO blood groups and the incidence of first and recurrent venous thromboembolic and arterial events. Blood donors in Denmark and Sweden between 1987 and 2012 were followed up for diagnosis of thromboembolism and arterial events. Poisson regression models were used to estimate incidence rate ratios as measures of relative risk. A total of 9170 venous and 24 653 arterial events occurred in 1 112 072 individuals during 13.6 million person-years of follow-up. Compared with blood group O, non-O blood groups were associated with higher incidence of both venous and arterial thromboembolic events. The highest rate ratios were observed for pregnancy-related venous thromboembolism (incidence rate ratio, 2.22; 95% confidence interval, 1.77-2.79), deep vein thrombosis (incidence rate ratio, 1.92; 95% confidence interval, 1.80-2.05), and pulmonary embolism (incidence rate ratio, 1.80; 95% confidence interval, 1.71-1.88). CONCLUSIONS In this healthy population of blood donors, non-O blood groups explain >30% of venous thromboembolic events. Although ABO blood groups may potentially be used with available prediction systems for identifying at-risk individuals, its clinical utility requires further comparison with other risk markers.

Abstract
OBJECTIVE Brazilian legislation has recently suggested the use of the qualitative hemolysin test instead of isohemagglutinin titers as prophylaxis for acute hemolysis related to plasma-incompatible platelet transfusions. The efficacy of this test in preventing hemolytic reactions has never been evaluated while isohemagglutinin titers have been extensively studied. The main objective of this study was to evaluate the correlation between the results of these two tests. The impact of each type of prophylaxis on the platelet inventory management and the ability of the qualitative hemolysin test to prevent red cell sensitization after the transfusion of incompatible units were also studied. METHODS A total of 246 donor blood samples were evaluated using both isohemagglutinin titers and the qualitative hemolysin test, and the results were statistically compared. Subsequently, 600 platelet units were tested using the hemolysin assay and the percentage of units unsuitable for transfusion was compared to historical data using isohemagglutinin titers (cut-off: 100). Moreover, ten patients who received units with minor ABO incompatibilities that were negative for hemolysis according to the qualitative hemolysin test were evaluated regarding the development of hemolysis and red cell sensitization (anti-A or anti-B). RESULTS Isohemagglutinin titration and the results of qualitative hemolysin test did not correlate. The routine implementation of the qualitative hemolysin test significantly increased the percentage of platelet units found unsuitable for transfusions (15-65%; p-value <0.001). Furthermore the qualitative hemolysin test did not prevent red blood cell sensitization in a small exploratory analysis. CONCLUSION Qualitative hemolysin test results do not correlate to those of isohemagglutinin titers and its implementation as the prophylaxis of choice for hemolysis associated with plasma-incompatible platelet transfusions lacks clinical support of safety and significantly affects platelet inventory management.

Abstract
Background The aim of this study was to evaluate the prognostic value of ABO blood group in Chinese patients with esophageal squamous cell carcinoma (ESCC) after esophagectomy. Methods This study was a retrospective review of the records of 548 patients with ESCC who received cytoreductive surgery between October 2002 and March 2007. The prognostic impact of ABO blood group on overall survival (OS) was analyzed. Results The median follow-up time was 37 months, and the 5-year OS was 43.3%. The overall 5-year OS was 41.2%, 49.7%, 44.0%, and 29.8% for the A, B, O, and AB groups, respectively (P=0.038). Among patients with negative lymph nodes (LNs), the 5-year OS was 59.0%, 68.2%, 57.9%, and 28.6% for the A, B, O, and AB groups, respectively (P<0.001), but blood type had no value in predicting the OS of patients with positive LNs (P=0.524). In multivariate Cox regression analysis of all patients, ABO blood group was not an independent prognostic factor of OS. However, in patients with negative LNs, blood type was an independent prognostic factor of OS, and the higher risk of death for patients of type AB versus non-AB significant in multivariate analyses (hazard ratio [HR], 2.576; 95% confidence interval [CI], 1.349–4.919; P=0.004). Conclusion ABO blood group is associated with survival in Chinese patients with ESCC. Patients with blood type AB had a significantly worse OS than patients with non-AB type, especially in patients with negative LNs.

Abstract
BACKGROUND One of the major determinants of von Willebrand factor (VWF) plasma levels is ABO blood group status, and individuals with blood group O have ~ 25% lower plasma levels. The exact mechanism behind this relationship remains unknown, although effects on clearance have been postulated. OBJECTIVES To determine whether clearance of VWF is directly dependent on the presence of ABH antigens on VWF. METHODS Three type 3 von Willebrand disease (VWD) patients were infused with Haemate-P, and the relative loading of VWF with ABH antigens at different time points was measured. VWF-deficient mice were injected with purified plasma-derived human VWF obtained from donors with either blood group A, blood group B, or blood group O. RESULTS In mice, we found no difference in clearance rate between plasma-derived blood group A, blood group B and blood group O VWF. Faster clearance of the blood group O VWF present in Haemate-P infused in type 3 VWD patients would have resulted in a relative increase in the loading of VWF with A and B antigens over time. However, we observed a two-fold decrease in the loading with A and B antigens in two out of three patients, and stable loading in the third patient. CONCLUSION There is no direct effect of ABH antigens on VWF in VWF clearance. We demonstrate that, in a direct comparison within one individual, blood group O VWF is not cleared faster than blood group A or blood group B VWF. Clearance differences between blood group O and non-blood group O individuals may therefore be related to the blood group status of the individual rather than the ABH antigen loading on VWF itself.

Abstract
Effect of ABO-incompatible liver transplantation on patients with severe hepatitis B (SHB) remains unclear. Herein, we summarized 22 cases with SHB in whom were performed emergency liver transplantation from ABO-incompatible donors. The immunosuppressive protocol consisted basiliximab, tacrolimus, steroids and mycophenolate mofetil. The mean MELD score was 35.2 ± 7.1. Major complications included rejection, infections, biliary complications, hepatic artery thrombosis or stenosis and portal vein thrombosis. Patient survival rates were 40.9%, 78.9% and 82.3% in 1 year, 29.2%, 66.8% and 72.9% in 3 years, and 21.9%, 60.1% and 62.5% in 5 years for ABO-incompatible, ABO-compatible and ABO-identical groups. Graft survival rates were 39%, 78.9% and 82.3% in 1 year, 27.8%, 66.4% and 71.1% in 3 years, and 20.9%, 57.9% and 61.0% in 5 years for incompatible, compatible and identical ABO graft-recipient match. The 1-, 3-, 5-year graft and patient survival rates of ABO-incompatible were distinctly lower than that of ABO-compatible group (P < 0.05). Our results suggested that ABO-incompatible liver transplantation might be a life-saving procedure for patients with SHB as a promising alternative operation when ABO-compatible donors are not available and at least bridges the second opportunity for liver retransplantation.

Abstract
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 and 2007. Using a case-cohort design, blood type was genotyped in 646 participants with stroke and a 1104-participant cohort random sample. Cox models that adjusted for Framingham stroke risk factors were used to assess the association of blood type with stroke. RESULTS During 5.8 years of follow-up, blood types A or B vs. type O were not associated with stroke. Blood type AB vs. O was associated with an increased risk of stroke (adjusted hazard ratio [HR] 1.83, 95% confidence interval [CI] 1.01-3.30). The association of blood type AB vs. 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 US population, it is a significant stroke risk factor and may play an important role in stroke risk in these individuals.

Abstract
BACKGROUND Non-O type of ABO blood group has been associated with a predisposition to coronary heart disease. It is thought that this association is partly mediated by increased cholesterol levels in non-O-type individuals. In this study, we sought to estimate the mediation effect size. METHODS AND RESULTS In a group of individuals (n=6476) undergoing coronary angiography, we detected associations of non-O type with significant coronary artery disease with >50% stenosis in ≥1 coronary arteries (odds ratio, 1.24; 95% confidence interval, 1.10-1.39; P=2.6×10(-4)) and with prevalent or incident myocardial infarction (odds ratio, 1.22; 95% confidence interval, 1.09-1.37; P=1.2×10(-3)). Subjects of non-O type had higher levels of total cholesterol, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol (mean [SEM] in mmol/L: 4.931[0.021], 3.041 [0.018], and 3.805 [0.020] in non-O type compared with 4.778 [0.026], 2.906 [0.021], and 3.669 [0.024] in O type; P=3.8×10(-7), P=1.5×10(-7), and P=3.1×10(-7), respectively). Mediation analyses indicated that 10% of the effect of non-O type on coronary artery disease susceptibility was mediated by increased low-density lipoprotein cholesterol level (P=7.8×10(-4)) and that 11% of the effect of non-O type on myocardial infarction risk was mediated by raised low-density lipoprotein cholesterol level (P=2.0×10(-3)). CONCLUSIONS In a model in which it is presumed that cholesterol is a mediator of the associations of ABO group with coronary artery disease and myocardial infarction, around 10% of the effect of non-O type on coronary artery disease and myocardial infarction susceptibility was mediated by its influence on low-density lipoprotein cholesterol level.

Abstract
PURPOSE ABO blood type is an established prognostic factor for several malignancies but its role in bladder urothelial carcinoma is largely unknown. We determined whether ABO blood type is associated with the outcome of transurethral resection of nonmuscle invasive bladder urothelial carcinoma. MATERIALS AND METHODS We retrospectively studied ABO blood types in 931 patients with primary nonmuscle invasive bladder urothelial carcinoma treated with transurethral bladder resection with or without intravesical instillation therapy. Disease recurrence and progression were analyzed with univariable and multivariable competing risks regression models. Median followup was 67 months. Discrimination was evaluated by the concordance index. RESULTS The ABO blood type was O, A, B and AB in 414 (44.5%), 360 (38.7%), 103 (11.1%) and 54 patients (5.8%), respectively. ABO blood type was significantly associated with outcome on univariable and multivariable analysis. Overall, patients with blood type O had worse recurrence and progression rates than those with A (p = 0.015 and 0.031) or B (p = 0.004 and 0.075, respectively). The concordance index of multivariable base models increased after including ABO blood type. CONCLUSIONS In patients with nonmuscle invasive bladder urothelial carcinoma the ABO blood type may predict the outcome. Those with blood type O showed the highest recurrence and progression rates. Including ABO blood type in multivariable models increases the accuracy of standard prognostic factors. Since the ABO blood type is available for most patients, it may represent an ideal adjunctive marker to predict recurrence and progression. The biological explanation and prognostic value of this finding must be further elucidated.

Abstract
Objective The aim of this study was to verify if ABO phenotypes are associated with allergic rhinitis. Methods 168 patients with allergic rhinitis and 168 control individuals from the same geographical region and paired by gender and age were enrolled in the study. ABO phenotypes were identified in red blood cells using the hemagglutination technique. The Fisher exact and chi-squared tests were employed to compare proportions. Statistical significance was set for an alpha error of 5% (p-value < 0.05). Results The overall differences in the frequencies of the ABO phenotypes of patients and controls were marginal (χ2: 7.569; degrees of freedom (DF): 3; p-value = 0.055) however the O blood group was associated with allergic rhinitis (χ2: 5.764; DF: 1; p-value = 0.016; OR: 1.735; CI 95%: 1.127-2.673). The differences in the frequencies of the O phenotype in patients and controls were statistically different for men (χ2: 8.520; DF: 1; p-value = 0.003) but not for women (χ2: 0.6375; DF: 1; p-value = 0.4246). The A phenotype was associated with protection (OR: 0.4385; CI 95%: 0.2043-0.9415; p-value = 0.049) and the O phenotype was associated with susceptibility (OR = 2.789; CI 95%: 1.385-5.616; p-value = 0.005) to allergic rhinitis only for men. Conclusion The O blood group phenotype is associated with allergic rhinitis in male but not in female patients.

Abstract
Background: Genetic risk factors for sporadic pancreatic cancer are largely unknown but actually under high exposure. Findings of correlations between the AB0 blood group system (Chromosome 9q34,1—q34,2) and the risk of pancreatic cancer (PC) in patients from Asia, America and south Europe have already been published. So far it is unclear, whether this correlation between blood group an PC incidence can be found in German patients as well. Methods: One hundred and sixty-six patients who underwent a resection of PC were evaluated in a period between 2000 and 2010. Blood group reference distribution for the German population is given as: 0: 41%; A: 43%; B: 11%; AB: 5%; Rhesus positive: 85%; Rhesus negative: 15%. Analyses were done using the non-parametric Chi2-test (p-value two sided; SPSS 19.0). Results: Median age was 62 (34–82) years. Gender: female 73/44%; male: 93/56%. Observed blood group proportions: 0: 43 (25.9%)/A: 94 (56.6%)/B: 16 (9.6%)/AB: 13 (7.8%)/Rhesus positive: 131 (78.9%)/negative: 35 (21.1%). We detected a significant difference to the German reference distribution of the AB0 system (Chi2 19.34, df 3, p < 0.001). Rhesus factor has no impact on AB0-distribution (Chi2 4.13, df 3, p = 0.25), but differs significantly from reference distribution—probably due to initial AB0-variation (Chi2 4.82, df 1, p = 0.028). The odds ratio for blood group A is 2.01 and for blood group 0 is 0.5. Conclusions: The incidence of PC in the German cohort is highly associated with the AB0-system as well. More patients with blood group A suffer from PC (p < 0.001) whereas blood group 0 was less frequent in patients with PC (p < 0.001). Thus, our findings support the results from other non-German surveys. The causal trigger points of this carcinogenesis correlation are still not known.

Abstract
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.

Abstract
Background In the past, ABO incompatibility was an absolute contraindication for solid organ transplantation. However, multiple recent trials have suggested strategies for overcoming the reactions between graft antigens and recipient antibodies that cause graft rejection. In this study, we determined the usefulness of plasma exchange (PE) for removing anti-A/B antibodies that cause hyperacute/acute humoral graft rejection in patients undergoing ABO-incompatible kidney transplantation. Methods In our study, 12 patients underwent ABO-incompatible kidney transplantation. All recipients received pre-transplantation conditioning by PE or intravenous immunoglobulin (IVIG) administration. After pre-transplantation conditioning, anti-A/B antibody titers were evaluated, and transplantation was performed when the titer was below 1:8. To assess the transplantation outcome, anti-A/B antibody titers, creatinine level, estimated glomerular filtration rate (eGFR), and proteinuria levels were measured. Results Anti-A/B antibody titers were below 1:8 in all patients at the time of transplantation. eGFR measured on post-transplant day 14 showed that 10 patients had immediate recovery of graft function, while 2 patients had slow recovery of graft function. Short-term outcomes of ABO-incompatible kidney transplantation (measured as creatinine levels) after reducing anti-A/B antibody titers were similar to those of ABO-compatible kidney transplantation. After transplantation, the anti-A/B antibody titers were below 1:8 in 7 patients, but the remaining 5 patients required post-transplantation PE and IVIG treatment to prevent antigen-antibody reactions. Conclusions With the increasing demand for kidney donations, interest in overcoming the ABO incompatibility barrier has increased. PE may be an important breakthrough in increasing the availability of kidneys for transplantation.

Abstract
Purpose The number of patients waiting for kidney transplantation is incessantly increasing, but the number of cadaveric kidney transplantations or ABO-compatible donors is so insufficient that ABO-incompatible kidney transplantation is being performed as an alternative. There are overseas studies and research showing that the 5-year survival rate and 5-year graft survival rate of ABO-incompatible kidney transplantation are not much different from those of ABO-compatible kidney transplantation. However, domestic research on the subject is rare. Therefore, we report the results of 22 ABO-incompatible kidney transplantation cases performed in our hospital. Materials and Methods This research was from 22 patients in our hospital who underwent ABO-incompatible kidney transplantation from 15 February 2007 to 20 May 2010. Results As yet, there have been no donor graft losses and no deaths after transplantation. The results of the two groups were analyzed by analysis of covariance of the creatinine value of the recipients at 6 months after the operation, corrected for the preoperative value in order to statistically identify whether there were differences in renal function after the operation between ABO-compatible and ABO-incompatible kidney transplantation. The results of the analysis of covariance showed no statistical difference in renal function after the operation between the two groups. Conclusions Even though there were not many cases, our initial results for ABO-incompatible kidney transplantation were positive. Considering the increasing number of patients waiting for kidney transplantation, longer-term domestic research studies of ABO-incompatible kidney transplantation are necessary.
