Metabolomic Analysis Uncovers Energy Supply Disturbance as an Underlying Mechanism of the Development of Alcohol-Associated Liver Cirrhosis.

ABSTRACT: Alcohol-associated liver disease (ALD) is caused by alcohol metabolism's effects on the liver. The underlying mechanisms from a metabolic view in the development of alcohol-associated liver cirrhosis (ALC) are still elusive. We performed an untargeted serum metabolomic analysis in 14 controls, 16 patients with ALD without cirrhosis (NC), 27 patients with compensated cirrhosis, and 79 patients with decompensated ALC. We identified two metabolic fingerprints associated with ALC development (38 metabolites) and those associated with hepatic decompensation (64 metabolites) in ALC. The cirrhosis-associated fingerprint (eigenmetabolite) showed a better capability to differentiate ALC from NC than the aspartate aminotransferase-to-platelet ratio index score. The eigenmetabolite associated with hepatic decompensation showed an increasing trend during the disease progression and was positively correlated with the Model for End-Stage Liver Disease score. These metabolic fingerprints belong to the metabolites in lipid metabolism, amino acid pathway, and intermediary metabolites in the tricarboxylic acid cycle. Conclusion: The metabolomic fingerprints suggest the disturbance of the metabolites associated with cellular energy supply as an underlying mechanism in the development and progression of alcoholic cirrhosis.

Project description:BackgroundPredicting the risk of alcohol relapse after a liver transplant for alcohol-associated liver disease is critical to guide candidate selection and optimize alcohol use disorder management. We aimed to use patient survey to augment the detection of alcohol relapse and its risk factors and to understand patient perceptions of the importance of alcohol abstinence.MethodsIn this retrospective cohort study, we used a telephone survey and chart review to assess the incidence of post-transplant harmful alcohol relapse, risk factors, and long-term outcomes for patients transplanted for alcohol-associated cirrhosis at our center from 2002 to 2016.ResultsOver the median follow-up of 5.9 years, 20.4% relapsed, with 9.3% harmful relapse after median of 4.0 years. The survey response rate was 44.0% (n=110). Of survey responders, 44.3% did not recall discussing alcohol in post-transplant clinics, and 17.6% of relapses were identified by the survey alone. In univariate analysis, shorter pretransplant sobriety (OR: 0.96 per month, p=0.02) and history of pretransplant relapse (OR: 2.99, p=0.02) were associated with post-transplant harmful relapse. After adjusting for these factors, High-risk Alcoholism Relapse score ≥4 predicted harmful relapse (OR: 3.43, p=0.049). A total of 27.3% of patients with both pretransplant relapse and High-risk Alcoholism Relapse score ≥4 relapsed to harmful use compared with 5.2% of those with 1 or neither risk factor (p < 0.001). Harmful relapse was associated with increased graft loss (30.4% vs. 17.4%) and inferior 10-year post-liver transplant survival (61.5% vs. 80.7%).ConclusionsIncorporating patient survey data allowed the detection of relapses otherwise unreported to clinicians, highlighting the need for novel strategies to detect relapse. Utilizing this augmented data, we identified pretransplant sobriety length, pretransplant relapse, and High-risk Alcoholism Relapse score ≥4 as risk factors that should be evaluated pretransplant to guide candidate selection and peritransplant alcohol use disorder management.
