Umbilical cord blood (UCB) represents a valuable graft source in the absence of a human leukocyte antigen (HLA)-matched donor for hematopoietic cell transplantation (HCT). Donor-specific anti-HLA antibodies (DSAs), targeting grafts with mismatched HLA antigens, pose a significant obstacle by increasing the risk of primary graft failure, delayed engraftment, and decreased survival. Existing literature on HLA desensitization has primarily focused on haploidentical transplants, and there is a lack of experience regarding the optimal strategy in UCB transplantation.

Background: Antibody-mediated rejection (ABMR) has become one of the leading causes of chronic lung graft dysfunction. However, in lung transplantation, this entity is sometimes difficult and controversial to diagnose. It is mainly caused by the appearance of donor-specific anti-human leukocyte antigen (HLA) antibodies (DSA), although there are situations with C4d deposits in biopsy in the absence of circulating DSA.

Objectives: Platelet transfusion refractoriness (PTR) is a frustrating clinical problem, and primary and persistent (P/P) PTR who experienced persistent PTR since the first transfusion was failed to be well recognized. This study aims to investigate the incidence and risk factors for P/P PTR.
Methods: Patients with hematologic disorders who underwent HLA high-resolution genotyping and donor-specific HLA antibody or panel reactive antibody (PRA) testing between January 2019 and March 2023 were reviewed.

Repeat HLA mismatches (RMM) have been historically associated with an increased risk of graft loss after repeat kidney transplantation, in particular HLA-DR RMM in sensitized recipients. As routine use of sensitive assays can at present prevent the transplantation of RMM in hosts with donor-specific antibodies, we hypothesized that RMM would no longer be associated with graft loss. We performed a registry analysis of the Collaborative Transplant Study database including 6711 patients who received a second kidney transplant (2 KT) between 2010 and 2021, with at least one HLA-A, -B or -DR mismatch.

Background And Hypothesis: Donor-derived cell-free DNA (dd-cfDNA) shows good diagnostic performance for the detection of antibody-mediated rejection (AMR) in kidney transplant recipients (KTR). However, the clinical benefits of dd-cfDNA monitoring need to be established. Early diagnosis of AMR at potentially reversible stages may be increasingly important due to emerging treatment options for AMR.
