Purpose Of ReviewPatients with cirrhosis are frequently hospitalized with acute decompensation and organ system failure - a syndrome referred to as acute on chronic liver failure (ACLF). These patients often require critical care intervention and experience significant mortality; however, established diagnostic and prognostic criteria are lacking. Given this, it remains imperative for intensivists to develop an expertise in common ACLF complications and management.Recent FindingsLiver transplantation serves as the definitive management strategy in ACLF. Traditional organ allocation procedures are based on the Model for Endstage Liver Disease score, which may not correlate with ACLF severity and the associated need for urgent liver transplantation. Recent studies have suggested favorable postliver transplantation outcomes in ACLF patients with multiorgan failure, emphasizing the need for further studies to elucidate optimal timing and candidacy for liver transplantation.SummaryCirrhosis is a chronic and progressive condition leaving patients vulnerable to acute decompensation necessitating the need for critical care intervention. Prompt recognition and implementation of targeted supportive therapies, together with consideration of urgent liver transplantation, are essential to combat the high short-term mortality of ACLF patients.
