Liver disease specialists from different countries have agreed on a definition of acute-on-chronic liver failure, ua.news reports, citing STAT News [1]. It is a common and potentially fatal complication in people who already have liver disease [1].

The condition occurs when a person with existing liver disease worsens because of an acute injury. It is not simply a prolonged course of the disease but its sudden exacerbation against the background of an already existing pathology [1]. In the United States, an example would be cirrhosis that developed over a long period and then suddenly worsened due to alcohol or a viral infection.

Previously, the condition was defined differently depending on the region where patients were located. This made it harder to distinguish acute-on-chronic liver failure from acute liver failure [1]. Unlike the former, acute liver failure develops rapidly and occurs without prior liver disease. The source does not specify which criteria were included in the agreed definition.
