Acute-on-chronic liver failure (ACLF) has been associated with excellent post-liver transplant (LT) outcomes at 1 year; however, the impact of alcohol as ACLF precipitant, specifically alcohol-associated hepatitis (AH), and as etiology of chronic liver disease remains uncertain. This study aimed to assess the effect of alcohol as ACLF precipitant and chronic liver disease etiology (alcohol-associated liver disease vs. non–alcohol-associated liver disease) on posttransplant outcomes. We performed a retrospective study using the Multi-Organ Dysfunction and Evaluation for LT Consortium database and included 640 patients with ACLF who underwent LT across 15 transplant centers in North America. The primary outcome was 1-year posttransplant survival. We used logistic regression and Cox proportional hazards to compare posttransplant survival, mortality risk, and health care utilization, adjusting for age, ACLF grade, comorbid diabetes mellitus, chronic kidney disease, and HCC. The median follow-up from LT was 2.8 years (P25–P75, 2.2–5.5 y) for patients with AH-ACLF (n=42) and 3.1 years (P25–P75, 1.6–4.9 y) for patients without AH (n=598). No significant difference was observed in 1-year survival after LT in patients with AH-ACLF versus those without AH ( p =0.36). Patients with AH had significantly higher health care utilization evidenced by greater length of stay (28.5 vs. 19.0 d, p =0.004; adjusted linear estimate 16.89, 95% CI: 7.66–26.11, p <0.001), higher rates of rehabilitation placement (71.4% vs. 41.8%, p =0.002; adjusted odds ratio: 4.13, 95% CI: 2.04–8.89, p <0.001), and non-ambulatory status (39.0% vs. 21.0%, p =0.005; adjusted odds ratio: 4.54, 95% CI: 1.90–10.79, p <0.001). Compared with other etiologies, alcohol-associated liver disease was not associated with differences in 1-year mortality, mortality risk over time, or health care utilization, after excluding patients with AH as ACLF precipitant. While there were no differences in 1-year survival, AH-ACLF was associated with higher health care resource utilization compared with other ACLF precipitants. LT centers should ensure adequate resources are allocated for the management of these patients.

Background and Aims: Severe alcohol-associated hepatitis (AH) is rising in incidence with a high mortality burden. While corticosteroids are recommended for eligible patients with severe AH, no guidance exists for the timing of steroid initiation, tapering regimens, and surveillance of adverse events. We aim to systematically review these variables and provide evidence-based recommendations for the inpatient and outpatient management of severe AH. Approach and Results: We performed a literature search from inception to May 30, 2024, to include clinical trials published in full form and assessed the quality of evidence using the Cochrane Risk of Bias tool. Data were collected on the timing of initiation, rate, and complications following steroid therapy, and taper regimens in the setting of severe AH. Of 28 studies that fulfilled our inclusion criteria, the median time from admission to steroid initiation was 6.5 days. The most common steroid dosing regimen was prednisolone 40 mg daily for 28 days. Twenty-five studies containing 3196 subjects reported adverse events, with exactly 50% in the steroid arm and the other half in the comparison arm. Infections, gastrointestinal bleeds, and renal impairment were the most frequently reported adverse events. Most infections occurred within the first month of the study. A 2-week steroid taper was the most frequently reported regimen. Conclusions: We recommend taking up to a week to systematically and thoroughly evaluate patients before initiating steroids, and vigilant monitoring in the first month of treatment. We also recommend the lowest possible steroid exposure with a 2-week steroid taper and close outpatient follow-up.

AbstractBackground & AimsNonalcoholic fatty liver disease (NAFLD) has been associated with sarcopenia. However, mortality in the setting of NAFLD‐related sarcopenia remains undefined. We aim to determine the all‐cause and cause‐specific mortality from sarcopenia among adults with NAFLD in the USA.Methods11 065 individuals in the Third National Health and Nutrition Examination Survey were studied and linked mortality through 2015 was analysed. NAFLD was diagnosed based on presence of ultrasonographic hepatic steatosis without other known liver diseases. Sarcopenia was defined as skeletal muscle index determined by bioelectrical impedance analysis. The Cox proportional hazard model was used to assess all‐cause mortality and cause‐specific mortality, and hazard ratio (HR) adjusted for known risk factors.ResultsDuring a median follow‐up of 23 years or more, sarcopenia was associated with increased all‐cause mortality (HR 1.27, 95% confidence interval [CI] 1.11‐1.44). Only in individuals with NAFLD, sarcopenia was associated with a higher risk for all‐cause mortality, while this association was absent in those without NAFLD. Individuals with both sarcopenia and NAFLD had a higher risk for all‐cause mortality (HR 1.28 95% CI 1.06‐1.55) compared with those without sarcopenia and NAFLD. Furthermore, sarcopenia was associated with a higher risk for cancer‐ and diabetes‐related mortality among those with NAFLD. This association was not noted in those without NAFLD.ConclusionIn this nationally representative sample of US adults, sarcopenia was associated with a higher risk for all‐cause, cancer‐ and diabetes‐related mortality in individuals with NAFLD.
