Characteristics and outcomes of acute-on-chronic liver failure patients with or without cirrhosis using two criteria

Abstract

The aim of the study was to identify the characteristics and outcomes in acute-on-chronic liver failure (ACLF) patients with or without cirrhosis using two criteria. Patients with acute deterioration of chronic hepatic disease or acute decompensation of cirrhosis were included retrospectively from April 10, 2016 to April 10, 2019. European Association for the Study of the Liver-chronic liver failure (EASL-CLIF) criterion except for consideration of cirrhosis and Chinese Group on the Study of Severe Hepatitis B (COSSH) criterion were used. Clinical features, laboratory data and survival curves were compared between the ACLF patients with and without cirrhosis. A total of 799 patients were included. Among them, 328 had COSSH and EASL ACLF, 197 had COSSH alone, and 104 had EASL alone. There were 11.6% more ACLF with COSSH criterion. Furthermore, EASL ACLF patients with non-cirrhosis vs. cirrhosis had different laboratory characteristics: ALT (423 vs. 154, p < 0.001), AST (303 vs. 157, p < 0.001), γ-GT (86 vs. 75, p < 0.01), and INR (2.7 vs. 2.6, p < 0.001) were significantly higher but creatinine (71 vs. 77, p < 0.01) were significantly lower; but importantly there was no statistical changes between non-cirrhosis and cirrhosis in EASL ACLF patients on 28-day (p = 0.398) and 90-day (p = 0.376) survival curves. However, 90-day (p = 0.030) survival curve was different between non-cirrhosis and cirrhosis in COSSH ACLF patients. COSSH ACLF score (auROC = 0.778 or 0.792, 95%CI 0.706–0.839 or 0.721–0.851) displayed the better prognostic ability for EASL ACLF patients with non-cirrhosis, but CLIF-C ACLF score (auROC = 0.757 or 0.796, 95%CI 0.701–0.807 or 0.743–0.843) still was the best prognostic scoring system in EASL ACLF patients with cirrhosis. In conclusions, EASL definition exhibited better performance on homogeneous identification of ACLF regardless of cirrhosis or non-cirrhosis. And COSSH ACLF score displayed the better prognostic ability for EASL ACLF patients without cirrhosis.
