Alcoholic hepatitis is a devastating form of acute liver injury seen in chronic alcohol abusers with significant morbidity and mortality. It is a multisystem disease that is precipitated by ingesting large quantities of alcohol with genetic and environmental factors playing a role. Prognostic criteria have been developed to predict disease severity and these criteria can serve as indicators to initiate medical therapy. Primary therapy remains abstinence and supportive care, as continued alcohol abuse is the most important risk factor for disease progression. The cornerstone of supportive care remains aggressive nutritional support, and although acute alcoholic hepatitis has been extensively studied, few specific medical therapies have been successful. Corticosteroids remain the most effective medical therapy available in improving short term survival in a select group of patients with alcoholic hepatitis; however, the long-term outcome of drug therapies is still not entirely clear and further clinical investigation is necessary. While liver transplantation for acute alcoholic hepatitis have demonstrated promising results, this practice remains controversial and has not been advocated universally, with most transplant centers requiring a prolonged period of abstinence before considering transplantation. Extracorporeal liver support devices, although still experimental, have been developed as a form of liver support to give additional time for liver regeneration. These have the potential for a significant therapeutic option in the future for this unfortunately dreadful disease.
酒精性肝炎是慢性酒精滥用者中出现的一种严重急性肝损伤形式,具有较高的发病率和死亡率。它是一种多系统疾病,由大量饮酒引发,遗传和环境因素也起作用。已经制定了预后标准来预测疾病严重程度,这些标准可作为启动药物治疗的指标。主要治疗方法仍然是戒酒和支持性护理,因为持续的酒精滥用是疾病进展的最重要危险因素。支持性护理的基石仍然是积极的营养支持,尽管急性酒精性肝炎已得到广泛研究,但很少有特定的药物治疗取得成功。皮质类固醇仍然是改善一组特定酒精性肝炎患者短期生存的最有效药物治疗方法;然而,药物治疗的长期结果仍不完全清楚,需要进一步的临床研究。虽然急性酒精性肝炎的肝移植已显示出有希望的结果,但这种做法仍存在争议,尚未得到普遍提倡,大多数移植中心在考虑移植前需要较长时间的戒酒。体外肝支持装置虽然仍处于实验阶段,但已被开发作为一种肝支持形式,为肝脏再生争取更多时间。对于这种不幸的可怕疾病,这些装置未来有可能成为一种重要的治疗选择。
