Acute-On-Chronic Liver Failure
Acute-on-chronic liver failure (ACLF) describes an increasingly recognized definition of a syndrome that frequently develops in patients with acute decompensation of chronic liver disease and is associated with a high mortality rate. Based on the results of the prospective CANONIC study, the first evidence-based diagnostic criteria and grading of ACLF in patients with cirrhosis have been proposed. As a next step, prognostic scores for ACLF (CLIF-C-ACLF score) and acute decompensation (CLIF-C AD score) have been developed. Even though the mechanisms leading to organ failure are not fully understood, systemic inflammation seems to play a crucial role in the development of ACLF. The “predisposition, injury, response, and organ” (PIRO) concept may be used to describe the underlying pathophysiological aspects of ACLF.
