BACKGROUND: Acute-on-chronic liver failure (ACLF), defined differently by different associations, lacks consensus on clinical profile, precipitating events and factors predicting mortality. This prospective multicentric study was conducted to determine the relevance of European Association for Study of Liver (EASL) and Asia Pacific Association for Study of Liver (APASL) definitions and to determine prognostic factors predicting the survival. METHODS: Consecutive patients over a 3-month period with any form of acute deterioration were evaluated for presence of ACLF, as defined by APASL or EASL-Chronic Liver Failure (CLIF) criteria. Those enrolled underwent complete evaluation for identifying the acute insults, underlying chronic etiologies, presence of organ failures, and short-term survival. RESULTS: Sixty-two patients (median age 53 years, 51 males) who presented with either raised bilirubin (n = 52), international normalized ratio (INR) >1.5 (n = 46), new onset ascites (n = 53), or hepatic encephalopathy (n = 39) were included in study. Forty-four patients (36 males, 25 alcoholics) satisfied APASL definition of ACLF, with a mortality rate of 43.1 %. Hepatic encephalopathy (p-value 0.022) was significantly associated with mortality. By CLIF-Sequential Organ Failure Assessment (SOFA) score criteria for organ failure, 50 patients (80.6 %) had at least 1 organ failure whereas 15 had ≥3 organ failures (mortality rate >75 %). Twenty-nine patients classified as ACLF (1, 2, or 3) as per EASL-CLIF criteria. Bacterial infection, >1 precipitating event, additional organ failure, total leukocyte count, INR, and serum creatinine were significantly higher in patients with ACLF across all grades. Mortality rates were 6.6 and >60 % in patients with ACLF only by APASL criteria vs. by both criteria, respectively. CONCLUSIONS: ACLF, as defined by APASL in terms of liver failure, identified some patients with better survival rates as compared to EASL-CLIF definition which identifies presence of additional organ failures and high mortality.
