Core Tip

Core tip: Acute-on-chronic liver failure (ACLF) is an increasingly recognized entity that is gaining acceptance in recent times. It is characterized by an acute impairment of an underlying chronic liver disease with high short-term mortality, produced by the development of organic failures and associated with precipitating event. However, little is known about the development and progression of this syndrome. Guided by the European Association for the Study of the Liver-Chronic Liver Failure-Consortium diagnostic criteria and the CANONIC study, we could establish that the prevalence of ACLF in our center was 29%, and that Child Pugh advanced stage, MELD score, presence of ascites and inflammation parameters were significant risk factors for ACLF.
