Alcohol-associated liver disease (ALD) is the most common indication for liver transplantation (LT) in the United States and Europe. A 6-month alcohol abstinence period has been required by many transplant programs prior to listing, which may influence wait-list (WL) outcomes. Therefore, we examined WL events in patients with ALD versus non-ALD with a special interest in whether these outcomes differed by sex. All US adults listed for LT from January 2002 to December 2016 were eligible except status 1 patients, Model for End-Stage Liver Disease exceptions, retransplants and those with acute alcoholic hepatitis. The outcomes of interest were cumulative WL death or being too sick and WL removal for improvement within 2 years of listing. Competing risk regression models were used to evaluate recipient factors associated with the outcomes. Among the 83,348 eligible WL patients, 23% had ALD. Unadjusted cumulative WL removal within 2 years was 19.0% for ALD versus 21.1% for non-ALD (P < 0.001). In fully adjusted models, ALD was associated with a significantly lower risk of WL removal for death or being too sick (subhazard ratio [SHR], 0.84; 95% confidence interval [CI], 0.81-0.87; P < 0.001) and a higher risk of removal for improvement (SHR, 2.91; 95% CI, 2.35-3.61; P < 0.001) versus non-ALD patients. After adjusting for potential confounders, women with ALD had a higher risk of removal for death or being too sick (SHR, 1.09; 95% CI, 1.00-1.08; P < 0.001) and a higher chance for improvement (SHR, 2.91; 95% CI, 2.35-3.61; P < 0.001) than men with ALD. In conclusion, WL candidates with ALD have more favorable WL outcomes than non-ALD patients with a 16% lower risk of removal for deterioration and 191% higher risk of removal for improvement. This result likely reflects the benefits of alcohol abstinence, but it suggests that listing criteria for ALD may be too restrictive, with patients who might derive benefit from LT not being listed.
酒精相关性肝病(ALD)是美国和欧洲进行肝移植(LT)的最常见指征。许多移植项目在将患者列入名单之前要求患者戒酒 6 个月,这可能会影响等候名单(WL)的结果。因此,我们研究了 ALD 患者与非 ALD 患者的 WL 事件,特别关注这些结果是否因性别而异。从 2002 年 1 月到 2016 年 12 月,所有美国成年人都有资格接受 LT,除非是 1 级患者、终末期肝病模型例外、再次移植和急性酒精性肝炎患者。感兴趣的结果是在列入名单后的 2 年内,累积 WL 死亡或病情恶化以及 WL 因改善而被移除。使用竞争风险回归模型来评估与结果相关的受体因素。在 83348 名符合 WL 条件的患者中,23%患有 ALD。未调整的 2 年内 WL 移除的累积率为 ALD 患者为 19.0%,而非 ALD 患者为 21.1%(P<0.001)。在完全调整的模型中,ALD 与 WL 因死亡或病情恶化而被移除的风险显著降低(亚危险比 [SHR],0.84;95%置信区间 [CI],0.81-0.87;P<0.001),与非 ALD 患者相比,改善移除的风险增加(SHR,2.91;95%CI,2.35-3.61;P<0.001)。在调整潜在混杂因素后,患有 ALD 的女性 WL 因死亡或病情恶化而被移除的风险更高(SHR,1.09;95%CI,1.00-1.08;P<0.001),改善移除的机会更高(SHR,2.91;95%CI,2.35-3.61;P<0.001)。总之,与非 ALD 患者相比,ALD 等候名单患者的 WL 结果更有利,恶化移除风险降低 16%,改善移除风险增加 191%。这一结果可能反映了戒酒的益处,但这表明 ALD 的列入标准可能过于严格,使可能从 LT 中获益的患者未被列入名单。
