Chronic rejection is the leading cause of organ transplant failure. Single episodes of acute rejection rarely lead to organ failure. It is possible to transplant animal tissues as well, such as from a pig or a cow, and use it for a human recipient.

Organ transplant recipients have been excluded from clinical trials with immune checkpoint inhibitors and the benefit and risks of such treatment have not been evaluated systematically in organ transplant recipients; however, several case reports on outcome have been pub-lished [10-32] with acute graft failure or rejection When your solid organ transplant (SOT) patients face complications, you need accurate and rapid results to minimize infection and graft failure. Antibody-mediated rejection (AMR), well-known as humoral or B-cell-mediated rejection, is a problematic post-transplant complication caused by anti-donor HLA antibodies.
