The significance of the 2018 Japanese diagnostic criteria for acute-on-chronic liver failure (ACLF) in identifying cirrhotic patients with poor outcomes following acute insults was evaluated through a nationwide survey. The majority of ACLF patients were diagnosed with severe alcoholic hepatitis, emphasizing the need for a specific therapeutic strategy for this subgroup of patients. The proposed diagnostic criteria were found to be useful in predicting mortality in ACLF patients, with disease condition, patient age, and number of organs with functional failure being significant factors.
Background The significance of the 2018 Japanese diagnostic criteria for acute-on-chronic liver failure (ACLF) has not yet been evaluated. Methods A nationwide survey was performed for patients with ACLF occurring between 2017 and 2019. Cirrhotic patients with a Child-Pugh score of 5-9 were diagnosed as having ACLF when liver failure (serum bilirubin level of >= 5.0 mg/dL and a prothrombin time international normalization rate [INR] of >= 1.5) occurred within 28 days after an acute insult. Patients who fulfilled either criterion (total serum bilirubin or INR) and/or those with indeterminate Child-Pugh scores at baseline were also enrolled. Results Among the 501 enrolled patients, 183 patients (37%) were diagnosed as having ACLF. The etiologies of the cirrhosis and acute insults were alcohol intake/abuse in 114 (62%) and 75 (41%) patients, respectively. Sixty-eight patients (37%) were also diagnosed as having severe alcoholic hepatitis. The survival rate without liver transplantation was 48% among the ACLF patients and 71% in the remaining patients (P < 0.01). A multivariate analysis revealed that the disease condition was significantly associated with mortality, with an odds ratio of 2.025 in ACLF patients relative to the remaining patients (P < 0.01), and patient age and the number of organs with functional failure were also associated with mortality among the ACLF patients. Conclusion The proposed diagnostic criteria for ACLF were useful for identifying cirrhotic patients with an unfavorable outcome following acute insults. A therapeutic strategy for patients with severe alcoholic hepatitis should be established, since such patients accounted for the majority of ACLF patients.
