Abstract
Antibody-mediated rejection is a rare complication following liver transplantation and there is a lack of a comprehensive treatment strategy to provide detailed information about the dose and duration of antibody-mediated rejection treatment. This study describes eight adult liver transplantation recipients who developed antibody-mediated rejection between 2002 and 2021 in our center, as well as a review of the literature on the reported cases of antibody-mediated rejection in liver transplantation recipients. Our center's medical records were reviewed retrospectively to extract the necessary data on patients' characteristics, management, and outcomes. Then, a comprehensive search using Embase, PubMed, Web of Science, Cochrane library, and Google Scholar databases was conducted without time limitation until June, 2021. Finally, a stepwise protocol was developed for managing acute, chronic, and recurrent antibody-mediated rejection in liver transplantation patients, based on our own experience, reported cases in the literature, and data from kidney transplantation. By review of the literature, 24 case studies containing 64 patients were identified and their management strategies and outcomes were evaluated. Although, various combinations of corticosteroids, plasma exchange, intravenous immunoglobulin, and biological agents are used in the treatment of acute antibody-mediated rejection in liver transplantation, treatment strategies should be classified according to the type, severity, and the timing of its onset. Given the importance of early treatment, rituximab and/or bortezomib should be started as soon as possible if no improvement in liver enzymes/bilirubin is observed during the initial treatment strategy using corticosteroids, plasma exchange and intravenous immunoglobulin.

Abstract
BACKGROUND An early and accurate diagnosis of liver antibody-mediated rejection (AMR) followed by timely intervention is important for clinical management but remains challenging. The aim of this study was to assess the clinicopathologic characteristics and outcomes of late acute AMR in pediatric liver transplantation recipients. METHODS We performed a retrospective review of 739 ABO-identical/compatible allograft liver biopsies from 199 pediatric transplantation recipients. RESULTS Based on Banff 2016 AMR criteria, 3 recipients fulfilled the criteria for definite for late acute AMR, 2 met the criteria for suspicious for AMR, and 2 were indeterminate for AMR. We further assessed the clinicopathologic characteristics of these 7 patients. All 7 patients had at least 1 biopsy with a histopathologic pattern compatible with acute AMR. Additionally, we observed accompanied moderately to markedly dilated portal/central veins and endothelialitis disproportionate to the degree of bile duct injury in all 7 patients; periportal/perivenular hepatocyte necrosis was seen in 6 of 7 patients; and arteritis was seen in 3 of 7 patients. In each case, microvascular C4d deposition was present in at least 1 biopsy. Posttransplant donor specific anti-HLA antibodies were detected in 5 patients. Two of 7 patients were retransplanted, and 2 died after developing refractory AMR. The remaining 5 patients were alive with stable graft function at a median follow-up of 4.1 years. CONCLUSIONS Our data suggest that acute AMR in pediatric liver grafts is rare, can develop late, and may be associated with graft loss or patient death. The recurrent histopathologic findings of moderately to markedly dilated portal/central veins and endothelialitis disproportionate to the degree of bile duct injury are features that appear unique to pediatric acute AMR of liver grafts.
