Research progress on humoral rejection after liver transplantation

Recent studies have shown that humoral rejection, or antibody-mediated rejection (AMR), is an important risk factor for graft failure. Transplant experts have accumulated some experience on the diagnosis and treatment of AMR after kidney transplantation. However, AMR after liver transplantation has not been fully understood until recently, and its pathogenesis, clinical manifestation, diagnosis and treatment are different from AMR after kidney transplantation. In the research progress, the AMR after liver transplantation was classified into hyper acute rejection, acute humoral rejection, chronic humoral rejection and the state of accommodation. The immunity mechanism of AMR after liver transplantation is also described. The different kinds of AMR after liver transplantation were diagnosed by analyzing the clinical manifestations, serum tests and pathological characteristics of the patients. Moreover, the risk factors of them were mentioned in the article. Then we also introduce the different strategies for prevention and treatment of AMR after liver transplantation. Therefore, based on the current research progress on AMR after liver transplantation, we analyze the future direction of progress. DOI: 10.11855/j.issn.0577-7402.2017.10.15
