{Abstract}: BACKGROUND: Acute-on-chronic liver failure (ACLF) is a common syndrome that occurs in patients with advanced chronic liver disease. It consists of the rapid failure of various organs and is associated with high short-term mortality. We aim to describe the main features and outcomes of inpatients who developed ACLF and to identify the factors associated with in-hospital and 28-day mortality.
METHODS: All patients meeting ACLF criteria with advanced chronic liver disease admitted for decompensation from January 2014 to December 2016 were identified. Clinical and biological data were collected at the time of ACLF diagnosis and at 3-7 days thereafter, as well as in-hospital and 28-day mortality.
RESULTS: Eighty nine out of 354 admission episodes (28%) developed ACLF, which was present at the time of admission in 72% of cases. A precipitating factor was identified in 83% of cases, the most frequent being infection (53%) and gastrointestinal bleeding (19%). In the multivariate regression analysis, the ACLF grade at 3-7 days after diagnosis was predictive of in-hospital mortality and 28-day mortality, and lower creatinine and bilirubin levels at the time of ACLF diagnosis and a precipitating factor other than bacterial infection were associated with ACLF reversion at 3-7 days.
CONCLUSIONS: ACLF is a frequent complication among patients with chronic liver disease admitted for acute decompensations and is associated with a high mortality rate and is related to the number of organs involved. Bacterial infection is the most frequent precipitating factor of ACLF and probably entails a worse prognosis.
