  • Acute-on-chronic liver failure (ACLF) refers to acute liver function decompensation on the basis of chronic liver diseases and is a complex clinical syndrome characterized by organ failure and high short-term mortality. ACLF is reversible and has diverse long-term outcomes and prognoses. The clinical classification of ACLF based on disease characteristics is of great significance for optimizing the management pathways for ACLF. With reference to the definition and clinical features of ACLF in the East and the West, this article redefines ACLF from the new perspective of onset manifestations and dynamic outcomes and proposes a new clinical classification of ACLF. The first classification of ACLF is based on the clinical features of intrahepatic and extrahepatic organ failure at disease onset, i.e., type Ⅰ ACLF (liver failure on the basis of chronic liver diseases) and type Ⅱ ACLF (acute decompensation on the basis of chronic liver diseases comorbid with multiple organ failure). The second classification is the dynamic clinical classification of ACLF based on clinical outcome, i.e., type A (rapid progression), type B (rapid recovery), type C (slow progression), type D (slow recovery), and type E (slow persistence). The proposed clinical classification of ACLF from the new perspective expects Eastern and Western scholars to have a more inclusive understanding of ACLF, narrow differences, optimize disease management paths, and rationally use medical resources, thereby providing a reference for clinicians.
