The selection of liver transplantation (LT) candidates with alcohol-use disorder (AUD) is influenced by the risk of alcohol relapse (AR) after LT. We aimed to investigate the risk factors of AR after LT and its impact on graft and recipient outcomes. A retrospective study was conducted that included all consecutive patients with AUD undergoing LT from January 2004 to April 2016 (n = 309), excluding patients with alcoholic hepatitis. Odds ratios (ORs) and 95% confidence intervals (CIs) for AR were analyzed by multinomial logistic regression. Cox regression with time-dependent covariates was used to analyze patient survival and graft cirrhosis. There were 70 (23%) patients who presented AR (median follow-up, 68 months), most of them (n = 44, 63%) presenting heavy AR. The probability of heavy AR was 2.3%, 7.5%, 12%, and 29% at 1, 3, 5, and 10 years after LT, respectively. The independent risk factors for heavy AR included a High-Risk Alcoholism Relapse (HRAR) score ≥3 (OR, 2.39; 95% CI, 1.02-5.56; P = 0.04) and the duration of abstinence (months) before LT (OR, 0.81; 95% CI, 0.66-0.98; P = 0.03). In recipients with <6 months of abstinence before LT, the probability of heavy AR after LT was higher in patients with an HRAR score ≥3 than in those with an HRAR score <3 (20%, 36.7%, and 47% versus 6.8%, 12.4%, and 27% at 1, 3, and 5 years, respectively; log-rank 0.013). The risk of graft cirrhosis was increased in patients with heavy AR (hazard ratio, 3.44; 95% CI, 1.58-7.57; P = 0.002) compared with nonrelapsers, with no differences in patient survival. In conclusion, the HRAR score is helpful in identifying the risk of harmful AR after LT in candidates with <6 months of alcohol abstinence without alcoholic hepatitis. These patients could benefit from a longterm integrative patient-centered approach after LT until lifestyle changes are implemented.
研究肝移植(LT)后酒精复饮(AR)的危险因素及其对移植物和受者结局的影响。
本研究采用回顾性队列研究,纳入了 2004 年 1 月至 2016 年 4 月期间因酒精使用障碍(AUD)接受 LT 的所有连续患者(n=309),排除了酒精性肝炎患者。采用多变量逻辑回归分析 AR 的危险因素。采用时依协变量 Cox 回归分析患者生存和移植物肝硬化情况。
70 例(23%)患者出现 AR(中位随访时间 68 个月),其中大多数(n=44,63%)为重度 AR。LT 后 1、3、5 和 10 年时重度 AR 的概率分别为 2.3%、7.5%、12%和 29%。发生重度 AR 的独立危险因素包括高风险酒精复饮(HRAR)评分≥3(比值比 2.39,95%置信区间 1.02-5.56;P=0.04)和 LT 前的戒酒时间(月)(比值比 0.81,95%置信区间 0.66-0.98;P=0.03)。LT 前戒酒时间<6 个月的受者中,HRAR 评分≥3 者的重度 AR 发生率高于 HRAR 评分<3 者(LT 后 1、3 和 5 年时分别为 20%、36.7%和 47%,6.8%、12.4%和 27%;log-rank P=0.013)。与非复饮者相比,重度 AR 患者的移植物肝硬化风险增加(风险比 3.44,95%置信区间 1.58-7.57;P=0.002),但患者生存率无差异。
对于 LT 前戒酒时间<6 个月且无酒精性肝炎的患者,HRAR 评分有助于识别 LT 后有害 AR 的风险。这些患者可以从 LT 后长期综合的以患者为中心的方法中获益,直到生活方式改变得以实施。
