Assessment of liver transplant benefit and a novel strategy for liver donor allocation in acute-on-chronic liver failure

Abstract

Acute-on-chronic liver failure (ACLF) is a type of complex clinical syndrome that is mainly characterized by acute deterioration of liver function based on chronic liver disease, hepatic and extrahepatic organ failures, and a high short-term mortality rate. The comprehensive medical treatment efficacy of ACLF is currently limited; thus, liver transplantation is the only viable potential treatment method. However, considering the severe liver donor shortage, economic and social costs, as well as the differences in disease severity and prognosis of different disease courses, it is particularly important to accurately assess the benefits of liver transplantation in patients with ACLF. Early identification and prediction, timing, prognosis, and survival benefits are discussed here by combining the latest research findings so as to optimize the liver transplantation treatment strategy for ACLF.
