Severe acute alcoholic liver disease (SAAH) unresponsive to medical therapy shows one-year-mortality rates of up to 90%. Most transplant centers request six months of alcohol abstinence prior to transplantation, the so-called "6-month rule." This regulation is not based on strong evidence, repeatedly making it a topic of controversial debates. The majority of patients with SAAH will die before fulfilling the 6-month rule. Therefore, liver transplantation (LT) protocols are becoming more flexible towards the rigid abstinence regulation, especially concerning SAAH patients. We conducted a literature review regarding LT in SAAH and its outcomes, including post-transplant mortality and recidivism. We studied available data on PubMed from 2011 and onwards whilst including articles dealing with genetic components, medical therapy and historic snapshots of alcoholism. Emerging studies recommend LT in SAAH not responding to medical therapies even without realizing the required abstinence period, since the majority of these patients would die within 6 months. SAAH without response to medical therapy has one-year-mortality rates of up to 90%. The 6-month rule is not based on strong evidence and is repeatedly a topic of controversial debates. There is genetic linkage to alcoholism and medical therapy is not as effective as estimated, yet. The 6-months-regulation has not shown to evidently decrease the risk of recidivism post-LT, which is a lifesaving treatment in SAAH patients. Insisting on rigid sobriety rules results in excluding patients with a low risk of recidivism from being transplanted. Moreover, the genetic linkage of alcoholism must be recognized.
严重急性酒精性肝病 (SAAH) 对药物治疗无反应,其一年死亡率高达 90%。大多数移植中心要求在移植前戒酒 6 个月,即所谓的“6 个月规则”。该规定没有坚实的证据支持,因此反复成为争议的话题。大多数 SAAH 患者在满足 6 个月戒酒期之前就会死亡。因此,肝移植 (LT) 方案对戒酒的硬性规定变得更加灵活,尤其是针对 SAAH 患者。我们对 SAAH 的 LT 及其结果进行了文献复习,包括移植后死亡率和复发率。我们在 PubMed 上检索了 2011 年及以后发表的相关数据,同时包括有关遗传因素、药物治疗和酒精中毒历史快照的文章。越来越多的研究建议,即使没有达到规定的戒酒期,对药物治疗无反应的 SAAH 患者也应进行 LT,因为这些患者中的大多数将在 6 个月内死亡。对药物治疗无反应的 SAAH 的一年死亡率高达 90%。6 个月规则没有坚实的证据支持,且反复成为争议的话题。酗酒与遗传有关,而且药物治疗并不像预期的那样有效,但目前还没有。6 个月的戒酒期并未明显降低 LT 后复发的风险,LT 是 SAAH 患者的一种救命治疗方法。坚持严格的戒酒规则会导致复发风险低的患者被排除在移植之外。此外,还必须认识到酗酒的遗传关联性。
