Blood group B candidates, many of whom represent ethnic minorities, have historically had diminished access to deceased donor kidney transplantation (DDKT). The new national kidney allocation system (KAS) preferentially allocates blood group A2/A2B deceased donor kidneys to B recipients to address this ethnic and blood group disparity. No study has yet examined the impact of KAS on A2 incompatible (A2i) DDKT for blood group B recipients overall or among minorities. A case-control study of adult blood group B DDKT recipients from 2013-2017 was performed, as reported to the Scientific Registry of Transplant Recipients...

BACKGROUND: The impact of HLA compatibility and positive lymphocyte cross-match (LCM) on organ transplantation is well-recognized particularly in kidney and heart transplantation, however, it is still debatable in liver transplantation (LT). So, the aim of this study was to evaluate the impact of HLA mismatch and positive LCM on the outcome of LT. METHODS: We retrospectively analyzed the data of all adult recipients who underwent living donor LT at our institute between January 2010 and July 2016...

BACKGROUND & AIMS: Living-donor liver transplantation (LDLT) can simultaneously cure hepatocellular carcinoma (HCC) and underlying liver cirrhosis, improving long-term results in patients with HCC. ABO-incompatible LDLT could expand the living-donor pool, reduce waiting times for deceased-donor liver transplantation, and improve long-term survival for some patients with HCC. METHODS: We retrospectively reviewed the medical records of patients undergoing LDLT for HCC from November 2008 to December 2015 at a single institution in Korea...

Antibody-mediated rejection (AMR) is one of the leading causes of allograft failure especially in patients undergoing ABO-incompatible (ABOi) renal transplantation. We hypothesized that complement inhibition with eculizumab, a C5 inhibitor, would protect against AMR and maintain graft function in ABOi renal transplant recipients. Four patients undergoing living donor kidney transplant from ABOi donors were treated with a 9-week eculizumab course without therapeutic plasma exchange, intravenous immunoglobulin, or splenectomy...

INTRODUCTION: Data suggest an additional role of T cells in antibody-mediated rejections. In 2001 a protocol for AB0-incompatible kidney transplantation based on B-cell-depleting anti-CD20 antibody rituximab, antigen-specific blood group IgG immunoadsorption, intravenous immunoglobulins, and triple immunosuppression was introduced in Europe, which used induction therapy with the use of interleukin-2 receptor antibody (IL2-RA) basiliximab. We used thymoglobulin in AB0-incompatible patients as induction in the face of high immunologic risk...

Anti-M is a frequently detected naturally occurring antibody that has been reported in various clinical settings and also in voluntary donors. We describe here the clinical and laboratory findings of 11 cases with anti-M detected at our center. This report is a retrospective study in which we reviewed our immunohematology laboratory records for cases involving anti-M. Both donor and patient data from a 28-month period (September 2014 to December 2016) were reviewed. During this period, 11 examples of anti-M were detected (8 patients, 1 voluntary whole blood donor, and 1 hematopoietic stem cell donor...

OBJECTIVES: To study the rate of ABO haemolytic anaemia of fetus and newborn (HDFN) in one institution over 6 years. BACKGROUND: ABO major incompatibility between mothers and their newborns occurs in about 10% of births. So, mothers with an O blood group may form IgG-class antibodies against A and B antigens, which could pass across the placenta and lead to a variable degree of HDFN in the newborn. METHODS: At our institution, we have reviewed data regarding ABO-based HDFN in the last 6 years...

Building on the successful military experience, interest has been rekindled in transfusing whole blood (WB) early in the resuscitation of traumatically injured civilians, often before their ABO group is known. WB efficiently provides treatment for shock and coagulopathy, as well as platelet hemostatic function, to patients losing large volumes of blood. Unlike group O uncrossmatched red blood cells (RBCs), group O WB contains a substantial amount of plasma, which is incompatible with the RBCs of all non-group O recipients...

BACKGROUND: It is well known that ABO blood group system incompatible kidney transplantation (ABOi-KT) is an effective strategy for end-stage renal disease. The main barrier for ABOi-KT is how to keep host B cell activation and blood group antibody titer in low levels. Moreover, the mechanism of B cell activation induced by blood group antigen was unclear in ABOi-KT. RESULTS: In this study, HK2 cells were identified to express blood group B antigen when cocultured with lymphocytes of blood group A...

BACKGROUND: How to choose an appropriate method to monitoring dynamic ABO chimera post-ABO-incompatible HSCT is crucial to not only assess the status of erythroid engraftment but also achieve personalized safety transfusion. METHODS: We evaluated the efficacy of micro gel column technique (MGCT) and flow cytometry (FCM) by series of artificial ABO chimera mixtures from 0.5% to 50% and by investigating 15 cases of ABO-incompatible HSCT patients with longitudinally ABO blood grouping and ABO chimera from RBCs and reticulocytes...

Platelets play a central role in the inflammation response via CD40 ligand (CD40L) expression, which may lead to transfusion reactions. The precise role of platelet CD40L-mediated inflammation in transfusion reactions is unclear. Therefore, we assessed the effects of in vitro blood mixing on platelet CD40L expression. In addition, we examined the effect of ABO compatibility on CD40L expression. Donor packed red blood cells were acquired from a blood bank, and recipient blood was obtained from patients undergoing cardiac surgery and prepared as washed platelets...

OBJECTIVE: To evaluate the utility and safety of high-dose mizoribine combination therapy using cyclosporine and tacrolimus as calcineurin inhibitors in patients undergoing kidney transplant. METHODS: The present study enrolled 156 patients who received kidney transplants in 18 institutions between 2009 and 2013. ABO-incompatible and/or pre-sensitized recipients were excluded. Immunosuppression used cyclosporine (88) or tacrolimus (68) as a calcineurin inhibitor, and the dosage was adjusted based on blood concentrations...

In addition to Rh and ABO incompatibilities subgroup incompatibilities may rarely play a role among the causes of hemolytic anemia and indirect hyperbilirubinemia in newborns. The most common minor blood group antigens that cause blood incompatibility between the mother and baby are C, c, E, e, Kell, Duffy, Diego, Kidd and MNSs antigens. In this article, a newborn in whom hyperbilirubinemia due to anti-E minor blood group incompatibility developed and was treated with phototherapy succesfully is presented and minor blood group incompatibilities due to anti-E are reviewed...

Antibodies against Lutheran blood group antigens have been observed during first-time pregnancy. Samples from a woman of African descent were tested in our immunohematology laboratory on several occasions since 2001. Her samples were phenotyped as Lu(a+b-), and anti-Lub was suspected but not identified. She was asked to make autologous donations in preparation for her delivery, which she did. In 2010, two antibodies were identified: anti-Lea and -Lub. Six years later, a third investigation was requested. This time, an antibody directed at a high-prevalence Lutheran antigen was found in addition to the anti-Lea and -Lub previously observed...

HLA-matched hematopoietic stem cell transplantation (HSCT) from red blood cell (RBC)-incompatible donors is not uncommon. The engraftment process following ABO-incompatible allogeneic HSCT results in the transition from patient blood group to donor blood group in the recipient. In contrast, most non-hematopoietic tissues retain expression of the patient's original blood group for life, and these antigens may adsorb from the plasma onto the donor-derived RBCs. Correct serologic interpretation of the ABO blood group during this engraftment process can be difficult...

INTRODUCTION: Measurement of alloantibody titer to a red cell antigen (ABO titers) is an integral part of management of ABO incompatible kidney transplants (ABOiKT). MATERIAL AND METHODS: There are different methods of titer estimation. Alloantibody detection by tube titration and Gel agglutination columns are accepted methodologies. It is essential to find the difference in titers between the two methods so as to set the 'cut-off' titer accordingly, depending upon the method used...
