Alcohol Consumption Post-Liver Transplantation: A Cross-Sectional Study

Abstract

<b><i>Background:</i></b> Listing patients with alcohol-associated liver disease (ALD) for liver transplant (LT) remains challenging especially due to the risk of alcohol resumption post-LT. We aimed to evaluate post-LT alcohol consumption at a Portuguese transplant center. <b><i>Methods:</i></b> We conducted a cross-sectional study including LT recipients from 2019 at Curry Cabral Hospital, Lisbon, Portugal. A pretested survey and a validated Portuguese translation of the Alcohol Use Disorder Identification Test (AUDIT) were applied via a telephone call. Alcohol consumption was defined by patients’ self-reports or a positive AUDIT. <b><i>Results:</i></b> In 2019, 122 patients underwent LT, and 99 patients answered the survey (June 2021). The mean (SD) age was 57 (10) years, 70 patients (70.7%) were males, and 49 (49.5%) underwent ALD-related LT. During a median (IQR) follow-up of 24 (20–26) months post-index LT, 22 (22.2%) recipients consumed any amount of alcohol: 14 had a drink monthly or less and 8 drank 2–4 times/month. On drinking days, 18 patients usually consumed 1–2 drinks and the remainder no more than 3–4 drinks. One patient reported having drunk ≥6 drinks on one occasion. All post-LT drinking recipients were considered low risk (score &#x3c;8) as per the AUDIT score (median [IQR] of 1 [1–2]). No patient reported alcohol-related problems, whether self-inflicted or toward others. Drinking recipients were younger (53 vs. 59 years, <i>p</i> = 0.020), had more non-ALD-related LT (72.7 vs. 44.2%, <i>p</i> = 0.018) and active smoking (31.8 vs. 10.4%, <i>p</i> = 0.037) than abstinent ones. <b><i>Conclusion:</i></b> In our cohort, about a quarter of LT recipients consumed alcohol early posttransplant, all with a low-risk pattern according to the AUDIT score.
