OBJECTIVE: Any erythrocyte transfusion among humans having type A or B blood groups is impossible due to antibodies causing fatal transfusion complications. A cross-match test is performed to prevent immune transfusion complications before transfusion. Our hypothesis is that the Fragment antibody (Fab) part of antibody (incomplete antibody) may be used to prevent an immune stimulus related to complete antibody. Therefore, we designed a pilot study to evaluate the effectiveness of these incomplete antibodies with using cross-match tests...

United Network for Organ Sharing (UNOS) policies allows for ABO non-identical liver transplantation (LT) in candidates with Model for End-Stage Liver Disease (MELD) scores greater than 30. Previous studies showed ABO non-identical LT resulted in an 18% and 55% net gain in livers for B and AB candidates. These results suggested that the current liver ABO allocation policies may need refinement. There are, however, strong associations between ABO blood groups and race/ethnicity. We hypothesized that race/ethnicity is associated with ABO non-identical LT and that this is primarily influenced by recipient ABO status...

One third of healthy willing living kidney donors are rejected due to ABO blood group incompatibility and donor specific antibody. This increases pre-transplant dialysis duration leading to increased morbidity and mortality on the kidney transplantation waiting list. Over the last decade kidney paired donation is most rapidly increased source of living kidney donors. In a kidney transplantation program dominated by living donor kidney transplantation, kidney paired donation is a legal and valid alternative strategy to increase living donor kidney transplantation...

Pigs represent a desirable animal model for the study of rejection in kidney transplantation with inbred Yucatan miniature swine (YMS) the most commonly studied strain due to well defined swine leukocyte antigen (SLA) genotypes. However, limitations to YMS may include cost and availability. Outbred Yorkshire pigs are widely available and significantly cheaper than YMS. Recent advances in SLA genotyping have allowed its application to outbred strains. On this basis, we theorized that Yorkshire pigs would be a viable alternative to YMS for the study of rejection in kidney transplantation...

With a relative shortage of type AB plasma, many centers have converted to type A plasma for resuscitation of patients whose blood type is unknown. The goal of this study is to determine outcomes for trauma patients who received incompatible plasma transfusions as part of a massive transfusion protocol (MTP). METHODS: As part of an EAST multi-institutional trial, registry and blood bank data were collected from 8 trauma centers for trauma patients (age ≥ 15 years) receiving emergency release plasma transfusions as part of MTPs from January 2012 - August 2016...

BACKGROUND: Neural tube defects (NTDs) are caused by the failure of neural tube formation which occurs during early embryonic development. NTDs are the most severe and leading cause of fetal mortality. Serine hydroxymethyl transferase (SHMT1) provides one-carbon units necessary for embryogenesis and defects in one-carbon production result in specific pathological conditions during pregnancy. The present study is aimed to evaluate the association of SHMT1 C1420T with NTD risk in the fetus using fetal, maternal and paternal groups by applying both case-control and family-based triad approaches...

BACKGROUND AND OBJECTIVES: ABO-incompatible haematopoietic stem cell transplantation (HSCT) presents a challenge to blood component transfusion. The aim of this study was to investigate the weak blood group A or B antigen expression by donor-derived group O red blood cells (RBC) observed following transfusion or minor ABO-incompatible HSCT. In addition, in vitro experiments were performed to elucidate possible mechanisms underlying this phenomenon. MATERIALS AND METHODS: A sensitive flow cytometry assay for the semi-quantification of RBC A/B antigen levels was used to assess patient samples and evaluate in vitro experiments...

BACKGROUND: The Dal blood group system was identified a decade ago by the accidental sensitization of a Dal- Dalmatian with a Dal+ blood transfusion. Similar Dal-related blood incompatibilities have been suspected in other Dalmatians, Doberman Pinschers, and other breeds. OBJECTIVES: To determine the prevalence and mode of inheritance of the Dal antigen expression in dogs. ANIMALS: A total of 1130 dogs including 128 Dalmatians, 432 Doberman Pinschers, 21 Shih Tzus, and 549 dogs of other breeds including 228 blood donors were recruited from North America between 2008 and 2015...

BACKGROUND AND OBJECTIVES: The US Food and Drug Administration and American Association of Blood Banks approved the type and screen approach in 1980s, long after antibody screen (AS) was introduced in 1950s. The present study omits conventional anti-human globulin (AHG) crossmatch and replaces it with immediate-spin (IS) crossmatch as part of pretransfusion testing in AS-negative patients to study the safety and effectiveness of IS crossmatch in recipients. MATERIALS AND METHODS: This prospective longitudinal study was conducted on over 5000 red cell units transfused to AS-negative patients admitted to the hospital...

BACKGROUND: The use of blood group O as "universal blood" for emergency whole blood transfusions carries the risk for a hemolytic transfusion reaction mediated by incompatible A/B antibodies. This risk can be minimized by assuring that the donor has a low titer of anti-A and anti-B. The level of these naturally occurring antibodies has been shown to be increased by vaccination with most biologically derived vaccines. This boostering effect has been investigated for the new generation of vaccines...

OBJECTIVES: Living-related kidney donation is the main source of renal grafts in Jordan, since kidneys from deceased donors are scarce. Although the Jordanian community accepts the idea of kidney donation to family members, not all potential donors manage to complete the required psychologic and medical evaluations. We review the causes of kidney-donation cancellation and suggest options to increase the number of available organs. MATERIALS AND METHODS: We performed a retrospective chart review of all potential living-related kidney donors at King Hussein Medical Center between January 2008 and June 2016...

OBJECTIVES: Chronic allograft dysfunction is a complex and multifactorial process characterized by progressive interstitial fibrosis and tubular atrophy. The finding of interstitial fibrosis and tubular atrophy is prevalent among kidney transplant patients receiving a calcineurin inhibitor-based immunosuppressive regimen and may be considered as a surrogate of allograft survival. Both immune (acute rejection episodes, sensitization, and HLA incompatibility) and nonimmune (donor age, delayed graft function, calcineurin inhibitor toxicity, infections, and hypertension) mechanisms play a role in chronic allograft dysfunction, and different causes all lead to similar histologic and clinical final pathways, with the end result of graft loss...

BACKGROUND: Grafts survive despite blood group antigens on the transplant being continuously exposed to antibodies in the blood of recipients in ABO-incompatible kidney transplantation (ABOi KT), owing to the mechanism of accommodation. We analyzed the immunodynamics of soluble ABH antigens in allografts from secretor donors and the influence of such immunodynamics on accommodation and subsequent graft survival in ABOi KT. METHODS: The genotype of a known human β-galactoside α-1,2-fucosyltransferase gene (FUT2), which determines soluble ABH antigen secretor status, was established in 32 donors for ABOi KT at the Severance Hospital, from June 2010 to July 2015...

BACKGROUND: Immunosuppressed, RhD-negative oncology patients tend to have lower rates of sensitization to the D antigen when they receive transfusion with RhD-positive blood components. Clinical factors associated with alloimmunization to the D antigen in RhD-negative oncology patients when they receive transfusion with RhD-positive red blood cells (RBCs) have not been well defined. STUDY DESIGN AND METHODS: This was a 4-year, retrospective analysis identifying RhD-negative oncology patients who received RhD-positive RBCs and were not previously alloimmunized to the D antigen...

BACKGROUND: Children with end-stage kidney disease may have co-existing iatrogenic or congenital vascular anomalies making transplantation difficult. We describe our approach in 5 recipients with vascular anomalies and significant co-morbidities, including one case of blood group incompatibility. METHODS: Five children aged 3 - 17 (median 7) years, weighing 14 - 34 (median 18) kg of whom 4 had occluded inferior vena cava or iliac veins and 2 had previous complex vascular reconstructions prior to transplantation for mid-aortic syndrome and multiple aortic aneurysms, respectively underwent renal transplantation...

BACKGROUND: More than 40% of patients awaiting a kidney transplant in the UK are sensitised with human leucocyte antigen (HLA) antibodies. Median time to transplantation for such patients is double that of unsensitised patients at about 74 months. Removing antibody to perform an HLA-incompatible (HLAi) living donor transplantation is perceived to be high risk, although patient survival data are limited. We compared survival of patients opting for an HLAi kidney transplant with that of similarly sensitised patients awaiting a compatible organ...
