Chronic intake of large quantities of alcohol causes damage to many organs, the liver being the most often affected one. In advanced countries, mortality due to liver diseases is directly proportional to alcohol consumption. 30 g of pure alcohol per day is regarded as a "safe" dose. Alcoholic liver disease may take the form of chronic illness (steatosis, steato-hepatitis, fibrosis and cirrhosis) or acute involvement (alcoholic hepatitis). Whereas steatosis is a relatively benign illness, the presence of cirrhosis of the liver means major life expectancy shortening. The actual stage of cirrhosis depends on the presence of complications--portal hypertension with bleeding oesophageal varices, ascites or hepatic encephalopathy. The median survival time of patients with advanced cirrhosis is 1-2 years. Serious alcoholic hepatitis has a mortality record of up to 50%. Absolute abstinence is a sine qua non condition for any treatment of alcoholic liver disease, the other therapeutic procedure are of a supportive nature and questionable significance. Corticoids can be used in the management of serious alcoholic hepatitis. Treatment in the stage of liver cirrhosis is similar to that in cirrhosis of any other aetiology. Cirrhotic patients who demonstrably abstain can be considered for transplantation leading to a markedly prolonged life expectancy.
长期大量饮酒会对许多器官造成损害,其中肝脏是最常受影响的器官。在发达国家,肝脏疾病导致的死亡率与酒精消费量直接相关。每天30克纯酒精被视为“安全”剂量。酒精性肝病可能表现为慢性疾病(脂肪变性、脂肪性肝炎、纤维化和肝硬化)或急性病变(酒精性肝炎)。虽然脂肪变性是一种相对良性的疾病,但肝硬化的存在意味着预期寿命大幅缩短。肝硬化的实际阶段取决于并发症的存在情况——门静脉高压伴食管静脉曲张出血、腹水或肝性脑病。晚期肝硬化患者的中位生存时间为1至2年。严重酒精性肝炎的死亡率高达50%。绝对戒酒是酒精性肝病任何治疗的必要条件,其他治疗方法具有支持性质且意义存疑。皮质类固醇可用于治疗严重酒精性肝炎。肝硬化阶段的治疗与其他病因引起的肝硬化相似。明显戒酒的肝硬化患者可考虑进行肝移植,这可显著延长预期寿命。
