Alcohol is the second most common cause of cirrhosis necessitating liver transplantation in the United States, yet rates of posttransplant drinking approach 50% and no controlled clinical trials of alcoholism treatment exist in this population. Eligible patients were randomly assigned to receive Motivational Enhancement Therapy (MET), or referral to local treatment sources ("treatment as usual" [TAU]). Addictive behavior, mood states, and general health were compared. Candor concerning alcohol use was encouraged by keeping drinking questionnaires in confidence, except in medical emergencies. Ninety-one subjects were studied; 46 received MET, 45 received TAU, 29 proceeded to transplantation (MET, n = 13; TAU, n = 16). A total of 69 subjects completed 24 weeks of observation, and 25 subjects were assessed at 96 weeks. No difference in study attendance was observed, but significantly more MET subjects attended 1 or more treatment sessions. Twenty-three subjects (25% of sample) drank after randomization but before transplant. Excluding an extreme outlier, MET drinkers had significantly fewer drinks per drinking days than TAU drinkers. Neither treatment plan resulted in significant variances in measures of psychosocial health. In conclusion, although MET afforded no significant benefit over TAU for mood or general health outcomes, this study provides some degree of support for MET to limit the quantity and frequency of pretransplant alcohol consumption among liver transplant candidates with alcohol dependence. However, because of the limited number of study subjects, these data must be interpreted cautiously. Further research to validate our findings or to identify better methods to identify and intervene with patients at risk of pretransplant and posttransplant drinking should continue.
在美国,酒精是导致肝硬化需要进行肝移植的第二大常见原因,然而,肝移植后饮酒的比例接近 50%,并且针对该人群的酒精中毒治疗还没有对照临床试验。合格的患者被随机分配接受动机增强治疗(MET)或转介到当地治疗机构(“常规治疗”[TAU])。比较了成瘾行为、情绪状态和一般健康状况。通过将饮酒问卷保密(紧急医疗情况除外)来鼓励坦诚对待饮酒问题。共有 91 名受试者接受了研究;46 人接受了 MET,45 人接受了 TAU,29 人进行了移植(MET,n=13;TAU,n=16)。共有 69 名受试者完成了 24 周的观察,25 名受试者在 96 周时接受了评估。未观察到研究出席率的差异,但接受 MET 的受试者参加 1 次或更多次治疗的比例明显更高。23 名受试者(占样本的 25%)在随机分组后但在移植前饮酒。排除一个极端异常值,MET 饮酒者的饮酒天数和饮酒量均明显少于 TAU 饮酒者。两种治疗方案都没有导致心理社会健康测量指标的显著差异。总之,尽管 MET 在情绪或一般健康结果方面没有明显优于 TAU,但本研究为 MET 提供了一定程度的支持,以限制酒精依赖的肝移植候选者在移植前和移植后饮酒的数量和频率。然而,由于研究对象数量有限,这些数据必须谨慎解释。应继续进行进一步的研究,以验证我们的发现或确定更好的方法来识别和干预有移植前和移植后饮酒风险的患者。
