Abstract
Aim
Heavy alcohol consumption is the most common etiology of acute-on-chronic liver failure (ACLF) in Japan. In some patients, ACLF is associated with a fatal outcome in less than 6 months. We evaluated the prognosis of patients with alcohol-related ACLF in our cohort and explored the prognostic factors.
Methods
Forty-six patients with alcoholic liver cirrhosis who fulfilled the Japanese diagnostic criteria for ACLF, including those classified as extended and/or probable, were enrolled in this study. Serum concentrations of inflammatory cytokines (interleukin [IL]-1β, IL-6, IL-8, IL-10, IL-12p70 and TNFα) were measured. We assessed prognosis and identified factors associated with survival.
Results
During the median 33-day observation period, 19 patients died, and 3 patients underwent living donor liver transplantation. Cumulative survival rates of patients treated without liver transplantation were 69, 48, 41, and 36% at 1, 3, 6, and 12 months, respectively. Eighteen of the 19 deceased patients died within 6 months after ACLF diagnosis. Serum concentrations of inflammatory cytokines were significantly elevated, and patients who underwent liver transplantation or who died within 6 months after admission had significantly higher serum IL-6 levels than the survival group. Multivariate analysis identified IL-6 > 23.3 pg/mL at admission and model for end-stage liver disease (MELD) score ≥ 25 on day 4 of admission as significant independent factors for mortality within 6 months.
Conclusion
Serum IL-6 level and Day-4 MELD were prognostic factors for alcohol-related ACLF. Early liver transplantation is a potential treatment option for patients whose prognosis is expected to be poor.
