The coronavirus disease 2019 (COVID‐19) pandemic has had a tremendous global impact since it began in November of 2019. However, there are concerns that the COVID‐19 pandemic will not affect all ...equally and that some populations will be particularly vulnerable. Relevant to liver disease, patients with alcohol use disorder (AUD) and alcohol‐associated liver disease (ALD) may be among the populations that are the most severely impacted. The reasons for this include being at a higher risk of severe COVID‐19 infection due to a depressed immune system and high‐risk underlying comorbidities, the injurious effect of COVID‐19 on the liver, the inability to attend regular visits with providers, diversion of hospital resources, and social isolation leading to psychological decompensation and increased drinking or relapse. As a result, we fear that there will be a dramatic rising tide of alcohol relapse, admissions for decompensated ALD, and an increase in newly diagnosed patients with AUD/ALD post–COVID‐19 pandemic. Providers and their institutions should implement preemptive strategies such as telehealth and aggressive patient outreach programs now to curb this anticipated problem. Liver transplantation (LT) centers should adapt to the pandemic by considering leniency to some LT candidates with ALD who cannot access appropriate alcohol treatment due to the current situation. In conclusion, the COVID‐19 pandemic will likely be especially detrimental to patients with AUD/ALD, and actions need to be taken now to limit the scope of this anticipated problem.

While liver transplantation (LT) has become a standard therapy for life-threatening alcohol related cirrhosis, LT as a treatment for severe alcoholic hepatitis (AH) has remained a taboo owing to ...concerns about the limited organ supply and the risk that the AH liver recipient will return to harmful drinking. The adoption of a 6-month abstinence requirement (the so-called ‘6-month rule’) by many centres made AH a contraindication to LT. Given the high short-term mortality of severe AH, the lack of effective medical therapies and an increasing recognition that the 6-month rule unfairly excluded otherwise favourable candidates, a seminal European pilot study of LT for AH was performed. The success of the European study, which has been corroborated in retrospective analyses from the United States, represented a paradigm shift in therapy for highly selected patients with severe AH who are not responding to medical therapy. However, prospective studies are urgently needed to resolve the controversies that still surround the criteria for selection of patients with AH for LT and the long-term outcomes of the associated alcohol use disorder.
Although liver transplantation (LT) for alcohol‐associated liver disease (ALD) is a well‐accepted practice, LT for severe alcoholic hepatitis (AH) remains controversial due to concerns about the ...limited organ supply and the risk of return to harmful drinking. Recognizing an increasing body of favorable evidence, a convergence of practice guideline recommendations from leading hepatology and gastroenterology societies have suggested that the length of abstinence should not be a sole criterion for LT selection and, thus, that LT may be considered in carefully selected severe AH patients with favorable psychosocial profiles not responding to medical therapy. We sought to examine this new consensus in greater detail, debating whether candidate selection criteria for LT in AH should be tightened or loosened.

Alcohol-associated hepatitis (AH) is a clinical syndrome of jaundice, abdominal pain, and anorexia due to prolonged heavy alcohol intake. AH is associated with changes in gene expression, cytokines, ...immune response, and the gut microbiome. There are limited biomarkers to diagnose and prognosticate in AH, but several non-invasive biomarkers are emerging. In this review, clinical risk-stratifying algorithms, promising AH biomarkers like cytokeratin-18 fragments, genetic polymorphisms, and microRNAs will be reviewed.
The American Consortium of Early Liver Transplantation for Alcoholic Hepatitis comprises 12 centers from 8 United Network for Organ Sharing regions studying early liver transplantation (LT) (without ...mandated period of sobriety) for patients with severe alcoholic hepatitis (AH). We analyzed the outcomes of these patients.
We performed a retrospective study of consecutive patients with a diagnosis of severe AH and no prior diagnosis of liver disease or episodes of AH, who underwent LT before 6 months of abstinence from 2006 through 2017 at 12 centers. We collected data on baseline characteristics, psychosocial profiles, level of alcohol consumption before LT, disease course and treatment, and outcomes of LT. The interval of alcohol abstinence was defined as the time between last drink and the date of LT. The primary outcomes were survival and alcohol use after LT, defined as slip or sustained.
Among 147 patients with AH who received liver transplants, the median duration of abstinence before LT was 55 days; 54% received corticosteroids for AH and the patients had a median Lille score of 0.82 and a median Sodium Model for End-Stage Liver Disease score of 39. Cumulative patient survival percentages after LT were 94% at 1 year (95% confidence interval CI, 89%–97%) and 84% at 3 years (95% CI, 75%–90%). Following hospital discharge after LT, 72% were abstinent, 18% had slips, and 11% had sustained alcohol use. The cumulative incidence of any alcohol use was 25% at 1 year (95% CI, 18%–34%) and 34% at 3 years (95% CI, 25%–44%) after LT. The cumulative incidence of sustained alcohol use was 10% at 1 year (95% CI, 6%–18%) and 17% at 3 years (95% CI, 10%–27%) after LT. In multivariable analysis, only younger age was associated with alcohol following LT (P = .01). Sustained alcohol use after LT was associated with increased risk of death (hazard ratio, 4.59; P = .01).
In a retrospective analysis of 147 patients who underwent early LT (before 6 months of abstinence) for severe AH, we found that most patients survive for 1 year (94%) and 3 years (84%), similar to patients receiving liver transplants for other indications. Sustained alcohol use after LT was infrequent but associated with increased mortality. Our findings support the selective use of LT as a treatment for severe AH. Prospective studies are needed to optimize selection criteria, management of patients after LT, and long-term outcomes.

Early liver transplant (LT) for alcohol‐associated disease (i.e., without a specific sobriety period) is controversial but increasingly used. Using the multicenter American Consortium of Early Liver ...Transplantation for Alcoholic Hepatitis (ACCELERATE‐AH) cohort, we aimed to develop a predictive tool to identify patients pretransplant with low risk for sustained alcohol use posttransplant to inform selection of candidates for early LT. We included consecutive ACCELERATE‐AH LT recipients between 2012 and 2017. All had clinically diagnosed severe alcoholic hepatitis (AH), no prior diagnosis of liver disease or AH, and underwent LT without a specific sobriety period. Logistic and Cox regression, classification and regression trees (CARTs), and least absolute shrinkage and selection operator (LASSO) regression were used to identify variables associated with sustained alcohol use post‐LT. Among 134 LT recipients for AH with median period of alcohol abstinence pre‐LT of 54 days, 74% were abstinent, 16% had slips only, and 10% had sustained alcohol use after a median 1.6 (interquartile range IQR: 0.7‐2.8) years follow‐up post‐LT. Four variables were associated with sustained use of alcohol post‐LT, forming the Sustained Alcohol Use Post‐LT (SALT) score (range: 0‐11): >10 drinks per day at initial hospitalization (+4 points), multiple prior rehabilitation attempts (+4 points), prior alcohol‐related legal issues (+2 points), and prior illicit substance abuse (+1 point). The C statistic was 0.76 (95% confidence interval CI: 0.68‐0.83). A SALT score ≥5 had a 25% positive predictive value (95% CI: 10%‐47%) and a SALT score of <5 had a 95% negative predictive value (95% CI: 89%‐98%) for sustained alcohol use post‐LT. In internal cross‐validation, the average C statistic was 0.74. Conclusion: A prognostic score, the SALT score, using four objective pretransplant variables identifies candidates with AH for early LT who are at low risk for sustained alcohol use posttransplant. This tool may assist in the selection of patients with AH for early LT or in guiding risk‐based interventions post‐LT.
Liver transplantation (LT) for alcohol-associated hepatitis (AH) remains controversial due to concerns about candidate selection subjectivity, post-LT alcohol relapse, and the potential exacerbation ...of LT disparities. Our aim was to design, perform, and examine the results of a simulated selection of candidates for LT for AH. Medical histories, psychosocial profiles and scores, and outcomes of 4 simulation candidates were presented and discussed at 2 multidisciplinary societal conferences with real-time polling of participant responses. Candidate psychosocial profiles represented a wide spectrum of alcohol relapse risk. The predictive accuracy of four psychosocial scores, Dallas consensus criteria, sustained alcohol use post-LT, Stanford Integrated Psychosocial Assessment for Transplant, and QuickTrans, were assessed. Overall, 68 providers, mostly academic transplant hepatologists, participated in the simulation. Using a democratic process of selection, a significant majority from both simulations voted to accept the lowest psychosocial risk candidate for LT (72% and 85%) and decline the highest risk candidate (78% and 90%). For the 2 borderline-risk candidates, a narrower majority voted to decline (56% and 65%; 64% and 82%). Two out of 4 patients had post-LT relapse. Predictive accuracies of Dallas, Stanford Integrated Psychosocial Assessment for Transplant, and Quicktrans scores were 50%, while sustained alcohol use post-LT was 25%. The majority of voting outcomes were concordant with post-LT relapse in 3 out of 4 patients. When defining "success" in LT for AH, providers prioritized allograft health and quality of life rather than strict abstinence. In this simulation of LT for AH using a democratic process of selection, we demonstrate its potential as a learning model to evaluate the accuracy of psychosocial scores in predicting post-LT relapse and the concordance of majority voting with post-LT outcomes. Provider definitions of "success" in LT for AH have shifted toward patient-centered outcomes.
