Assessment and Management of the Liver Transplant Candidate with Acute-on-Chronic Liver Failure
Summary
This chapter provides insights on the understanding of acute-on-chronic liver failure (ACLF), with emphasis on established diagnostic and prognostic criteria, and treatment/management options for transplant candidates. ACLF is a specific syndrome characterized by: acute deterioration of cirrhosis; failure of one or more organs; and high short-term mortality. ACLF is a major worldwide medical problem, with prevalence rates in at-risk populations in the region of 20-35%. The development of ACLF is associated with a precipitating factor. Patients with ACLF can be categorized according to the types of precipitating factors: hepatic or extrahepatic insults. Patients with hepatic ACLF and those with extrahepatic ACLF have different clinical phenotypes and prognosis. The accepted strategy for management of ACLF consists of early recognition and treatment of the precipitating event, and supportive care with intensive monitoring and support of failing organs. Liver transplantation represents the only definitive therapeutic option for patients with ACLF.
