Anti-human leukocyte antigen (anti-HLA) sensitization in lung transplant recipients (LTRs) can significantly impact graft survival and patient outcomes. The global pandemic, induced by the SARS-CoV-2 virus, brought about numerous challenges in the medical sphere, including potential alterations in HLA immunization patterns among LTRs. A retrospective analysis of LTRs group transplanted from July 2018 to 1 March 2020 (pre-pandemic) was compared with patients transplanted from 1 March 2020 to December 2022 (during the pandemic).

Transplantation in this group is enabled by desensitization methods, i.e.

There are no data regarding the incidence of anti-HLA recipient-specific antibodies (RSAs) and their role after transplantation. Here we aimed to identify the incidence of RSAs in a mismatched related hematopoietic cell donor population and their possible impact on immune-mediated complications, such as acute graft-versus-host disease (aGVHD), and complications resulting from endothelial injury, such as transplantation-associated thrombotic microangiopathy (TA-TMA) and veno-occlusive disease (VOD).

In this paper, we focus on antibody-mediated rejection, which can cause acute and more importantly chronic graft dysfunction and subsequently shortened allograft survival. We present the case of a 46-year-old patient who, two months after lung transplantation (LTx), developed AMR manifested by the deterioration of graft function and de novo production of donor-specific antibodies (DSA): DQ3 (DQ7, DQ8, DQ9).
