Early Liver Transplant for Alcohol-associated Liver Disease Has Excellent Survival but Higher Rates of Harmful Alcohol Use.

BACKGROUND & AIMS: Early liver transplantation (LT) for alcohol-associated liver disease (ALD) has increased worldwide. Short-term outcomes have been favorable, but data on longer-term outcomes are lacking. METHODS: Single-center retrospective study of primary LT recipients between 2010 and 2020, with follow-up through July 1, 2022. Survival analysis was performed using log rank, Cox models, and Kaplan-Meier method. Cox models were created to identify variables associated with mortality; logistic regression to identify variables associated with post-LT alcohol use. RESULTS: Of 708 patients who underwent LT, 110 (15.5%) had ALD and abstinence <6 months prior to LT (ELT), 234 (33.1%) had ALD and alcohol abstinence >6 months (SLT), and 364 (51.4%) had non-ALD diagnoses. Median follow-up was 4.6 years (interquartile range, 2.6-7.3 years). ELT recipients were younger (P = .001) with median abstinence pre-LT of 61.5 days. On adjusted Cox model, post-LT survival was similar in ELT and SLT (hazard ratio [HR], 1.31; P = .30) and superior to non-ALD (HR, 1.68; P = .04). Alcohol use (40.9% vs 21.8%; P < .001) and harmful alcohol use (31.2% vs 16.0%; P = .002) were more common in ELT recipients. Harmful alcohol use was associated with post-LT mortality on univariate (HR, 1.69; P = .03), but not multivariable regression (HR, 1.54; P = .10). Recurrence of decompensated ALD trended toward more common in ELT (9.1% vs 4.4%; P = .09). Greater than 6 months pre-LT abstinence was associated with a decreased risk of harmful alcohol use (odds ratio, 0.42; P = .001), but not in a multivariable model (odds ratio, 0.71; P = .33). CONCLUSIONS: Patients who undergo ELT for ALD have similar or better survival than other diagnoses in the first 10 years after LT despite a higher incidence of post-LT alcohol use.

The Level of Alcohol Consumption in the Prior Year Does Not Impact Clinical Outcomes in Patients With Alcohol-Associated Hepatitis.

The 10-item Alcohol Use Disorders Identification Test (AUDIT-10) and its shorter form, AUDIT-Consumption (AUDIT-C), are questionnaires used to characterize severity of drinking. We hypothesized that liver injury and short-term outcomes of alcohol-associated hepatitis (AH) would correlate with a patient's recent alcohol consumption as determined by AUDIT-10 and AUDIT-C. We analyzed a prospective international database of patients with AH diagnosed based on the National Institute on Alcohol Abuse and Alcoholism (NIAAA) standard definitions. All patients were interviewed using AUDIT-10. Primary outcomes included the discriminatory ability of the AUDIT-10 and AUDIT-C scores for predicting survival status at 28 and 90 days and severity of liver injury, as measured by Model for End-Stage Liver Disease-sodium (MELD-Na). The relationship between AUDIT scores and survival status was quantified by calculating the area under the curve of the receiver operating characteristic analysis. The relationship between AUDIT scores and MELD-Na was examined using correlation coefficients. In 245 patients (age range 25-75 years; 35% female), we found no correlation between AUDIT-10 or AUDIT-C scores and either 28- or 90-day mortality. Similarly, there was no correlation between AUDIT-10 and AUDIT-C and MELD-Na scores. There was a strong positive correlation between MELD-Na and 28- and 90-day mortality. Additional measures of severity of alcohol use (average grams of alcohol consumed per day, years of drinking, convictions for driving under the influence, and rehabilitation attempts) and psychosocial factors (marriage, paid employment, and level of social support) had no influence on MELD-Na. In patients presenting with AH, AUDIT-10 and AUDIT-C were predictors of neither clinical severity of liver disease nor short-term mortality, suggesting that level of alcohol consumption in the prior year is not key to the presenting features or outcome of AH.

Psychosocial assessment in liver transplantation (LT): an analysis of short-term outcomes.

BACKGROUND: Our research showed that patients with alcohol-associated liver disease (ALD) had more severe liver disease than those without a diagnosis of ALD yet were less likely to be selected for transplant listing due to their increased psychosocial vulnerability. This study aims to answer whether this vulnerability translates to worse short-term outcomes after transplant listing. METHODS: A total of 187 patients were approved for liver transplant listing and are included in the present retrospective study. We collected dates of transplantation, retransplantation, death, and pathologic data for evidence of rejection, and reviewed alcohol biomarkers and documentation for evidence of alcohol use. RESULTS: The ALD cohort had higher Stanford Integrated Psychosocial Assessment for Transplant (SIPAT) scores (39.4 vs. 22.5, p <0.001) and Model for End-Stage Liver Disease (MELD)-Na scores (25.0 vs. 18.5, p <0.001) compared with the non-ALD cohort. Forty-nine (59.7%) subjects with ALD and 60 (57.1%, p =0.71) subjects without ALD subsequently received a liver transplant. Overall mortality was similar between the 2 groups (20.7% ALD vs. 21.0% non-ALD, p =0.97). Neither the SIPAT score (HR: 0.98, 95% CI: 0.96-1.00, p =0.11) nor MELD-Na score (HR 0.99, 95% CI 0.95-1.02, p =0.40) were associated with mortality. Patients with ALD were more likely to have alcohol biomarkers tested both before (84.1% vs. 24.8% non-ALD, p <0.001) and after liver transplantation (74.0% vs. 16.7% non-ALD, p <0.001). SIPAT score was associated with alcohol use after listing (OR: 1.03, 95% CI: 1.0-1.07, p =0.04), although a return to alcohol use was not associated with mortality (HR: 1.60, 95% CI: 0.63-4.10, p =0.33). CONCLUSION: Patients with ALD had higher psychosocial risk compared with patients without a diagnosis of ALD who were placed on the waitlist, but had similar short-term outcomes including mortality, transplantation, and rejection. Although a high SIPAT score was predictive of alcohol use, in the short-term, alcohol use after transplant listing was not associated with mortality.
