Alcohol is a major cause of liver cirrhosis in the Western world and accounts for the majority of cases of liver cirrhosis seen in district general hospitals in the UK. The three most widely recognised forms of alcoholic liver disease are alcoholic fatty liver (steatosis), acute alcoholic hepatitis, and alcoholic cirrhosis. The exact pathogenesis of alcoholic liver injury is still not clear but immune mediated and free radical hepatic injury are thought to be important. There is increasing interest in genetic factors predisposing to hepatic injury in susceptible individuals. Diagnosis is based on accurate history, raised serum markers such as gamma-glutamyltransferase, mean corpuscular volume, and IgA and liver histology when obtainable. Abstinence is the most important aspect of treatment. Newer drugs such as acamprosate and naltrexone are used to reduce alcohol craving. Vitamin supplements and nutrition are vital while corticosteroids have a role in acute alcoholic hepatitis where there is no evidence of gastrointestinal haemorrhage or sepsis. Liver transplantation has excellent results in abstinent patients with end stage liver disease but there are concerns about recidivism after transplant.
在西方世界,酒精是肝硬化的主要病因,在英国地区综合医院所见的肝硬化病例中占大多数。三种最广为人知的酒精性肝病形式为酒精性脂肪肝(脂肪变性)、急性酒精性肝炎和酒精性肝硬化。酒精性肝损伤的确切发病机制仍不清楚,但免疫介导和自由基介导的肝损伤被认为很重要。人们越来越关注易患个体中导致肝损伤的遗传因素。诊断基于准确的病史、升高的血清标志物如γ-谷氨酰转移酶、平均红细胞体积和IgA,以及可获得时的肝脏组织学检查。戒酒是治疗最重要的方面。阿坎酸和纳曲酮等新型药物用于减少对酒精的渴望。维生素补充剂和营养至关重要,而皮质类固醇在无胃肠道出血或脓毒症证据的急性酒精性肝炎中发挥作用。肝移植对于终末期肝病的戒酒患者效果极佳,但人们担心移植后会复发。
