BACKGROUND: Acute-on-chronic liver failure (ACLF) is a rapidly progressive syndrome marked by high short-term mortality. While diabetes mellitus (DM) is known to worsen liver-related outcomes, its specific impact on alcohol-related ACLF (ALD-ACLF) remains underexplored. This study aimed to assess the prognostic impact of DM on 90-day outcomes in ALD-ACLF using data from the APASL ACLF Research Consortium (AARC) database.
METHODS: This observational study involved data from 5612 ACLF patients with documented 90-day outcomes. We identified 2096 patients with ALD-ACLF precipitated by alcoholic hepatitis. Patients with non-ALD etiologies, mixed etiologies, or non-alcoholic precipitants were excluded. Diabetic and non-diabetic patients were compared using 1:2 propensity score matching based on key baseline covariates. Survival outcomes were assessed using Kaplan-Meier analysis and multivariable Cox regression.
RESULTS: After matching, 109 diabetic patients were compared with 218 well-matched non-diabetic controls. Diabetic patients had significantly lower overall survival (32 vs. 57%) and transplant-free survival (31 vs. 50%) compared to non-diabetics (log-rank p
