INTRODUCTION: Recently, based on data from the PREDICT study, the European Foundation for the Study of Chronic Liver Failure (EF‐CLIF) consortium proposed pathophysiological/prognostic groups in hospitalized patients with cirrhosis: stable decompensated cirrhosis (SDC), unstable decompensated cirrhosis (UDC), pre‐acute‐on‐chronic liver failure (pre‐ACLF), and ACLF. We evaluated the outcomes of these subgroups in a real‐life cohort of hospitalized patients with cirrhosis. METHODS: Patients with cirrhosis developing first AD between 09/2010 and 12/2017 at the Vienna General Hospital were evaluated for this retrospective analysis. RESULTS: Two hundred and ten patients with cirrhosis (aged 57.6 ± 11.8 years) including n = 45 (21.4%) SDC, n = 100 (47.6%) UDC, n = 28 (13.3%) pre‐ACLF, and n = 37 (17.6%) with ACLF were considered. The proposed AD subgroups discriminated between patients with favorable (1‐year mortality: SDC: 6.7% and UDC: 19.6%) and dismal prognosis (90‐day mortality: pre‐ACLF: 42.9%). Interestingly, systemic inflammation gradually increased (e.g., C‐reactive protein, SDC: 0.9 mg/dl, vs. UDC: 2.0 mg/dl vs. pre‐ACLF: 3.2 mg/dl, p < 0.001) while renal function was progressively deteriorating (creatinine levels, SDC: 0.8 mg/dl vs. UDC: 0.9 mg/dl vs. pre‐ACLF: 1.2 mg/dl, p < 0.001) across prognostic subgroups in patients with cirrhosis. DISCUSSION: The recently proposed pathophysiological/prognostic EF‐CLIF subgroups are also reproduceable in a real‐life cohort of cirrhotic patients. As ACLF is a common and important complication, patients at risk of pre‐ACLF at index AD should be evaluated and if disease proceeds, been treated early and aggressively to avoid excessive mortality.
