RESUMO
The prevalence of alcohol use disorder (AUD) has been steadily increasing over the past decade. In parallel, alcohol-associated liver disease (ALD) has been increasing at an alarming rate, especially among young patients. Data suggest that most patients with ALD do not receive AUD therapy. Although liver transplantation is the only curative therapy for end-stage ALD, transplant candidacy is often a matter of debate given concerns about patients being under-treated for AUD and fears of post-transplantation relapse affecting the allograft. In this Review, we discuss diagnosis, predictors and effects of relapse, behavioural therapies and pharmacotherapies, and we also propose an integrative, multidisciplinary and multimodality approach for treating AUD in patients with cirrhosis, especially in the setting of liver transplantation. Notably, this approach takes into account the utility of AUD pharmacotherapy in patients on immunosuppressive medications and those with renal impairment after liver transplantation. We also propose a comprehensive and objective definition of relapse utilizing contemporary biomarkers to guide future clinical trials. Future research using the proposed approach and definition is warranted with the goal of optimizing AUD treatment in patients with cirrhosis, the transplant selection process and post-transplantation care of patients with AUD.

OBJECTIVE: To determine risk factors for waitlist mortality in children with biliary atresia listed for liver transplantation. STUDY DESIGN: There were 2704 children with biliary atresia (<12 years of age) listed for a first liver transplant (2002-2018) in the United Network for Organ Sharing database. Fine-Gray regression models for competing risks analysis (main risk = waitlist mortality/delisting owing to too sick; competing risk = liver transplantation) were implemented to identify risk factors for waitlist mortality. RESULTS: The median waitlist time was 83 days (IQR, 34-191). The cumulative incidence of waitlist mortality was 5.2%. In multivariable analysis (n = 2253), increasing bilirubin level (P < .001), portal vein thrombosis (P = .03), and ventilator dependence (P < .001) at listing were associated with a higher risk, whereas weight ≥10 kg at listing (P = .009) was associated with a lower risk of waitlist mortality. When ascites at listing was included in multivariable analysis (n = 1376), it was associated with a higher risk for the composite outcome (P = .03). Encephalopathy at listing was not associated with waitlist mortality (n = 1376; P = .15). CONCLUSIONS: These parameters can be used to more objectively prioritize children with biliary atresia awaiting liver transplantation and identify children with biliary atresia-related end-stage liver disease at high-risk of mortality.
