Abstract
BACKGROUND Microvascular injury resulting from activation and exocytosis are early signs of tissue damage caused by allografting. However, humoral anti-graft reactions are not easily detectable in transplant biopsies. The aim of this study was to establish a bioassay to recapitulate this process in a prospective approach. METHODS The study was executed by using our previously established protocol to isolate and freeze the donors' microvascular endothelial cells (MVEC) at the transplantation (34 living-related donors and 26 cadaver donors); and to collect sera from the recipients before the transplantation, one-, three- and six-months after transplantation. The activation and exocytosis of the MVEC were determined by incubating the donors' cultures with the recipients' sera. We determined if there was any endothelial activation by quantifying the releases of monocyte chemotactic protein-1 (MCP-1) and interleukin 8 (IL-8) in supernatants and the expressions of membrane intercellular adhesion molecule-1 (CD54) and intercellular adhesion molecule-1 (CD106) by flow cytometry. Endothelial exocytosis was determined by quantifying soluble E-selectin (CD62E) and cytoplasmic von Willebrand Factor (vWF) in supernatants. Endothelial activation or exocytosis was considered positive when the fold change (≧1.5) of post-transplantation to pre-transplantation was reached. We also monitored serum PRA and cytokines using Luminex multiple-plex and cytometric bead-based assay respectively. RESULTS We found 41.2% recipients (14 out of 34, ranging from 1.5 to 5.2 folds, p < 0.05) exhibited positive MVEC activation in the first month after transplantation as determined by IL-8 levels; 26.5% recipients (9 out of 34, ranging from 1.5 to 11.8 folds, p < 0.05) by MCP-1 levels. In the group of three months post-transplantation, 70.6% patients were positive (12 out of 17, ranging from 1.8 to 87.1 folds, p < 0.05) by IL-8 increased levels; 24% recipients (4 out of 17, ranging from 1.8 to 50.5 folds, p < 0.05) measured by MCP-1 levels. However, these changes disappeared six months after transplantation. Flow cytometric data showed that a time-dependent of CD54+ and CD106+ expressions existed over the course of six months. Most CD54+ and CD106+ cells were CD31- (platelet-endothelial cell adhesion molecule-1), though CD31+/CD106+ (37.5%, 3 out of 8) and CD31+/CD106+ (25%. 2 out of 8) were seen. When comparing donor MVEC activation to their recipient's proinflammatory cytokine levels or PRA status, we could not draw a conclusion regarding the connections between them. The sera collected from recipients at either one- or three-months after allografting did not significantly induce the release of either soluble CD62E or vWF (p > 0.05), indicating exocytosis was not significantly involved in the acute phase of allografting. CONCLUSIONS This bioassay enables us to detect the activation and exocytosis of donor MVEC elicited by respective sera from mismatched kidney recipients.

Abstract
Patients with MDS often suffer from anemia, and less often thrombocytopenia, and thus are a frequently transfused population. Red blood cell (RBC) transfusion may be used to improve functional capacity and quality of life in this population, while platelet transfusion is typically used to decrease bleeding risk. Despite the frequency of transfusion in patients with MDS, there are few well-defined guidelines for RBC and platelet transfusion support in this patient population. Transfusion is not without risk-patients with MDS who are frequently transfused may develop alloantibodies to RBC antigens, which can lead to hemolytic transfusion reactions and delays in obtaining compatible RBCs. Regular communication between clinicians and blood bank physicians is crucial to ensure that patients with MDS receive the most appropriate blood products.

Abstract
Salmonella Enteritidis (SE) causes both horizontal and vertical transmission of diseases in poultry industry and is also one of the main causes of human food poisoning. Sequence analysis of the sef operon of poultry-derived Salmonella serotypes showed the presence of an entire sef operon in SE, whereas only sef pseudogenes were found in Salmonella Gallinarum and Salmonella Pullorum. Subsequently, the sef operon of SE was cloned into the pBR322 plasmid and expressed in a modified Escherichia coli strain SE5000. sef operon expression was demonstrated using sodium dodecyl sulfate-polyacrylamide gel electrophoresis, western blot, agglutination assay, and transmission electron microscopy. The results showed that SE5000+Sef, but not SE5000+pBR322, could specifically react with SE-positive chicken serum in an agglutination assay, which could be clearly visualized by the naked eye within less than 2 min. In contrast, SE5000+Sef could not be recognized in Salmonella Gallinarum- and Salmonella Pullorum-positive chicken sera. Next, taking advantage of the exclusive presence of an entire sef operon in SE, we set up an agglutination-based detection system to monitor the dynamics of Sef-targeted antibody from SE-infected chicks for 47 days. Using the proposed detection method, SE was readily detectable starting from 2 weeks post-infection. Finally, we compared the proposed SE5000+Sef-based detection system with commercially available agglutination antigen using the classical bacterial isolation and identification procedure as reference. The results showed that the SE5000+Sef system was more consistent with the results of bacterial isolation and identification with almost 100% accuracy. We established a simple, sensitive, and cheap agglutination method for rapid and specific detection of SE-infected chickens, which can facilitate epidemiological investigation and eradication of SE infections. KEY POINTS: • Only the Salmonella Enteritidis serotype expressed Sef fimbriae in chicken infected with SE. • A rapid, large-scale method of detection by the naked eye of detection of SE-infected chicken is presented.

Abstract
BACKGROUND Alloimmunisation and haemolytic transfusion reactions (HTRs) can occur in patients with sickle cell disease (SCD) despite providing phenotype-matched red blood cell (RBC) transfusions. Variant RBC antigen gene alleles/polymorphisms can lead to discrepancies in serological phenotyping. We evaluated differences between RBC antigen genotyping and phenotyping methods and retrospectively assessed if partial antigen expression may lead to increased risk of alloimmunisation and HTRs in SCD patients at a tertiary centre in Canada. METHODS RBC antigen phenotyping and genotyping were performed by a reference laboratory on consenting SCD patients. Patient demographic, clinical and transfusion-related data were obtained from a local transfusion registry and chart review after research ethics board approval. RESULTS A total of 106 SCD patients were enrolled, and 91% (n = 96) showed additional clinically relevant genotyping information when compared to serological phenotyping alone. FY*02N.01 (FY*B GATA-1) (n = 95; 90%) and RH variant alleles (n = 52, 49%; majority accompanied by FY*02N.01) were common, the latter with putative partial antigen expression in 25 patients. Variability in genotype-phenotype antigen prediction occurred mostly in the Rh system, notably with the e antigen (kappa: 0.17). Fifteen (14.2%) patients had a history of alloimmunisation, with five having HTR documented; no differences in clinical outcomes were found in patients with partial antigen expression. Genotype/extended-phenotype matching strategies may have prevented alloimmunisation events. CONCLUSION We show a high frequency of variant alleles/polymorphisms in the SCD population, where genotyping may complement serological phenotyping. Genotyping SCD patients before transfusion may prevent alloimmunisation and HTRs, and knowledge of the FY*02N.01 variant allele increases feasibility of finding compatible blood.

Abstract
Our understanding of the mechanisms underlying HLA associations with inflammatory arthritis continues to evolve. Disease associations have been refined, and interactions of HLA genotype with other genes and environmental risk factors in determining disease risk have been identified. This Review provides basic information on the genetics and molecular function of HLA molecules, as well as general features of HLA associations with disease. Evidence is discussed regarding the various peptide-dependent and peptide-independent mechanisms by which HLA alleles might contribute to the pathogenesis of three types of inflammatory arthritis: rheumatoid arthritis, spondyloarthritis and systemic juvenile idiopathic arthritis. Also discussed are HLA allelic associations that shed light on the genetic heterogeneity of inflammatory arthritides and on the relationships between adult and paediatric forms of arthritis. Clinical implications range from improved diagnosis and outcome prediction to the possibility of using HLA associations in developing personalized strategies for the treatment and prevention of these diseases.

Abstract
Virtual crossmatch (VXM) compares a transplant candidate's unacceptable antigens to the HLA typing of the donor before an organ offer is accepted and, in selected cases, supplant a prospective physical crossmatch. However, deceased donor typing can be ambiguous, leading to uncertainty in compatibility prediction. We have developed a prototype web application that utilizes ambiguous HLA molecular typing data to predict which unacceptable antigens are present in the donor HLA genotype as donor-specific antibodies (DSA). The application compares a candidate's listed unacceptable antigens to computed probabilities of all possible two-field donor HLA alleles and UNOS antigens. The VIrtual CrossmaTch for mOleculaR HLA typing (VICTOR) tool can be accessed at http://www.transplanttoolbox.org/victor. We reanalyzed historical VXM cases where a transplant center's manual interpretation of molecular typing results influenced offer evaluation. We found that interpretation of ambiguous donor molecular typing data using imputation could one day influence VXM decisions if the DSA predictions were rigorously validated. Standardized interpretation of molecular typing data, if applied to the match run, could also change which offers are made. HLA typing ambiguity has been an underappreciated source of immunological risk in organ transplantation. The VICTOR tool can serve as a testbed for development of allocation policies with the aim of decreasing offers refused due to HLA incompatibility.

Abstract
OBJECTIVES This study aimed to analyse the allele frequency of blood group antigens in the Korean population and other ethnic populations and the association of blood group antigens with red blood cell (RBC) alloantibodies. BACKGROUND Blood group antigen genotyping can support patients undergoing frequent transfusions who have alloantibodies and antibodies against high-prevalence blood group antigens. METHODS Twenty-nine single nucleotide variations and 37 blood group antigens were tested. Samples requested for routine blood typing were collected from Jan to Apr 2016. Genotyping was performed on 145 Korean samples and was confirmed by bidirectional sequencing and serologic tests. The allele frequency data were compared with previous genotyping datasets (three datasets from Korea and one each from China, Europe, Asia, and the USA). Alloantibody frequencies and blood group antigens from the electronic medical record of 1772 cases were examined. RESULTS E antigen was higher in the Korean population compared to that of Asian and European populations. K, Kpa , Fyb and Doa allele frequencies were lower compared to other ethnic populations. RBC alloantibodies with frequencies (%) greater than 1% from the 1772 cases were as follows: anti-E, 36·7%, anti-C, 17·7%; anti-c 7·39%; anti-M, 5·9%; anti-e, 5·2%; anti-Jka , 2·9%; and anti-Fya , 1·1%. Blood group antigens and alloantibody frequencies revealed inverse trends that did not reach statistical significance. CONCLUSION The allele frequency of blood group antigens assessed by high-throughput methods provided reliable and valuable information that could be used for maintaining donor pools and providing compatible blood for genotyped patients.

Abstract
Most sickle cell disease (SCD) patients rely on blood transfusion as their main treatment strategy. However, frequent blood transfusion poses the risk of alloimmunization. On average, 30% of SCD patients will alloimmunize while other patient groups form antibodies less frequently. Identification of genetic markers may help to predict which patients are at risk to form alloantibodies. The aim of this study was to evaluate whether genetic variations in the Toll-like receptor pathway or in genes previously associated with antibody-mediated conditions are associated with red blood cell (RBC) alloimmunization in a cohort of SCD patients. In this case-control study, cases had a documented history of alloimmunization while controls had received ≥20 RBC units without alloantibody formation. We used a customized single nucleotide polymorphism (SNP) panel to genotype 690 SNPs in 275 (130 controls, 145 cases) patients. Frequencies were compared using multiple logistic regression analysis. In our primary analysis, no SNPs were found to be significantly associated with alloimmunization after correction for multiple testing. However, in a secondary analysis with a less stringent threshold for significance we found 19 moderately associated SNPs. Among others, SNPs in TLR1/TANK and MALT1 were associated with a higher alloimmunization risk, while SNPs in STAM/IFNAR1 and STAT4 conferred a lower alloimmunization risk.

Abstract
Red blood cell (RBC) transfusion support represents a critical component of sickle cell disease (SCD) management. However, as with any therapeutic intervention, RBC transfusion is not without risk. Repeat exposure to allogeneic RBCs can result in the development of RBC alloantibodies that can make it difficult to find compatible RBCs for future transfusions and can directly increase the risk of developing acute or delayed hemolytic transfusion reactions, which can be further complicated by hyperhemolysis. Several prophylactic and treatment strategies have been employed in an effort to reduce or prevent hemolytic transfusion reactions. However, conflicting data exist regarding the efficacy of many of these approaches. We will explore the challenges associated with predicting, preventing and treating different types of hemolytic transfusion reactions in patients with SCD in addition to describing future strategies that may aid in the management of the complex transfusion requirements of SCD patients.

Abstract
Red blood cell (RBC) transfusion therapy is a key component in the comprehensive management of patients with sickle cell disease (SCD). Consequently, most adult SCD patients will receive at least one, and many will receive more than a hundred RBC transfusions in their lifetime. SCD patients develop RBC alloantibodies much more frequently than non-SCD transfused patients, which often make the selection of compatible RBCs extremely difficult, in addition to placing patients at significantly higher risk of suffering from delayed hemolytic transfusion reactions (DHTRs). Similar to alloimunization, DHTRs are much more common in patients with SCD compared to other heavily transfused populations, and are particularly consequential due to their propensity to cause hyperhemolysis, a life-threatening phenomenon in which both transfused RBCs in addition to the patient's own sickle-erythrocytes are destroyed. In this review, we highlight the incidence and pathophysiology of DHTRs; illustrate common presentations, appropriate evaluations and outcomes of DHTRs in patients with SCD; and discuss strategies for preventing or reducing the likelihood of DHTRs from occurring.

Abstract
Objectives To assess current knowledge of National Heart, Lung and Blood Institutes (NHLBI) and Thalassemia International Federation (TIF) recommendations, blood banking practices and perceived challenges among transfusion services in the management of patients with haemoglobinopathies. Background Previous reports have demonstrated variations in transfusion practices for sickle cell disease (SCD) and thalassemia patients. Recently, NHLBI/TIF have provided transfusion recommendations for patients with haemoglobinopathies. Methods A cross‐sectional survey was conducted of transfusion services from the state of Georgia previously identified as having SCD/thalassemia populations. The survey assessed transfusion service practices in pre‐transfusion testing and blood product selection; awareness/implementation of NHLBI/TIF transfusion‐based recommendations and perceived challenges in transfusing haemoglobinopathy patients. Results Responses were received from 35 of 49 (71%) institutions. Only institutions indicating transfusing SCD or thalassemia patients (32) were included in analysis. Seventy‐one percent of non‐sickle cell treatment centres (SCTCs) and 20% of non‐thalassemia treatment centres follow NHLBI and TIF recommendations to perform a red blood cell phenotype beyond ABO/Rh(D) and provide Rh and Kell prophylactically matched units for SCD and thalassemia patients, respectively. Forty percent of institutions (33% of non‐SCTCs) employ RBC genotyping to evaluate the red cell phenotype for SCD patients. Over 77% of institutions do not utilise a reliable method to identify SCD patients prior to transfusion, such as a required question/answer field on type/screen or crossmatch orders. Conclusion Many healthcare systems' transfusion practices for haemoglobinopathy patients are discordant with NHLBI/TIF recommendations. Efforts are needed to increase awareness and implementation of current recommendations among all transfusion services seeing these patients.

Abstract
INTRODUCTION Allogeneic blood product transfusion is common in pediatric patients undergoing cardiopulmonary bypass although it is associated with an increased risk for adverse events. Furthermore, numerous donor exposures may affect future blood transfusion needs and human leukocyte antigen matching for patients who may ultimately require cardiac transplantation. Autologous intraoperative blood collection and retransfusion is a known method of blood preservation, but has not been extensively practiced in pediatric patients. In this study we assess the feasibility of this blood conservation technique in small children with complex congenital heart defects undergoing cardiopulmonary bypass. METHODS After Institutional Review Board approval, we retrospectively reviewed the medical records of children weighing <10 kg who underwent cardiopulmonary bypass over a 2-year period. Eighteen patients underwent autologous intraoperative blood collection and retransfusion and comprised the study group. Eighteen control patients were chosen by a 1:1 matched design using preoperative hematocrit, surgical procedure, and body weight. Multiple corresponding demographic and surgical variables, transfusion data, and clinical outcomes were compared. RESULTS Patient demographics, operative parameters and preoperative laboratory, and coagulation values were similar between the two groups. Despite the removal of autologous blood, study patients did not require more inotropic support prior to cardiopulmonary bypass. They also did not experience a significant increase in bleeding as measured by 24-hour postoperative chest tube output. Study patients were exposed to significantly fewer donor units intraoperatively and within the first 24 hours postoperatively. DISCUSSION The use of autologous intraoperative blood collection and retransfusion is a feasible option for small children with complex congenital heart defects undergoing cardiopulmonary bypass. Study patients received significantly fewer donor exposures without an increase in postoperative bleeding. Children who require multiple cardiac surgeries or eventually transplantation could benefit from this blood conservation technique.

Abstract
Flow cytometric crossmatches (FCXM) are routinely performed to support living-donor renal transplantation. While long a laboratory mainstay, a physical crossmatch is costly, time consuming, and frequently poses interpretative conundrums with both false-positive and false- negative results. Given the increased utilization of the virtual crossmatch (vXM) in the deceased donor setting, our aim was to assess its utility in living donor evaluations. We reviewed 100 living donor FCXMs and retrospectively performed a vXM for each pair. Seventy-five (75) cases were concordant, (i.e., FCXM-/vXM- or FCXM+/vXM+) while 25 cases were discordant; Five were vXM+/FCXM- and 20 were FCXM+/vXM-. Since donor-specific antibodies (DSA) were not detected in the 20 FCXM+/vXM- cases, these were interpreted as false-positive, i.e., due to non-HLA antibodies. Importantly, none of these patients, when transplanted across a positive FCXM, experienced early antibody mediated rejection or subsequently developed HLA DSA. These data reveal that, for the vast majority of living donor evaluations, a vXM is an acceptable vetting procedure.
