The natural history of alcoholic cirrhosis, especially in Asian countries, has not been completely understood thus far.
We retrospectively compared the outcomes of compensated cirrhosis between Japanese alcoholic and hepatitis C virus (HCV)-infected patients.
A total of 227 patients (75 alcoholic and 152 HCV-infected patients) with compensated cirrhosis were enrolled. The median follow-up period was 4.9 years. The cumulative rates of hepatocellular carcinoma (HCC) development were significantly lower in the alcoholic patients than in the HCV-infected patients (6.8% vs 50.3% at 10 years, P = 0.0003), while the cumulative rates of hepatic decompensation (37.4% vs 51.7% at 10 years) and survival (53.8% vs 47.4% at 10 years) did not significantly differ between the two groups (Kaplan-Meir analysis). The main causes of death were hepatic failure and non-hepatic diseases in the alcoholic patients and HCC and hepatic failure in the HCV-infected patients. Multivariate analyses using the Cox proportional hazard model revealed that the risk of HCC was lower in alcoholic cirrhosis than in HCV-related cirrhosis (hazard ratio (HR), 0.46), while the risk of hepatic decompensation and mortality was the same. Predictors of decreased survival were non-abstinence (HR, 2.53) in the alcoholic patients and low serum albumin level (1.58) in the HCV-infected patients.
Survival of patients with alcoholic cirrhosis was similar to that of patients with HCV-related cirrhosis. The risk of HCC development was lower in alcoholic cirrhosis than in HCV-related cirrhosis. Abstinence from alcohol was important for improving the survival of patients with alcoholic cirrhosis.
迄今为止,酒精性肝硬化的自然病程,尤其是在亚洲国家,尚未完全明了。
我们回顾性比较了日本酒精性肝硬化患者与丙型肝炎病毒(HCV)感染所致肝硬化患者的代偿期肝硬化结局。
共纳入227例代偿期肝硬化患者(75例酒精性肝硬化患者和152例HCV感染所致肝硬化患者)。中位随访期为4.9年。酒精性肝硬化患者肝细胞癌(HCC)发生的累积率显著低于HCV感染所致肝硬化患者(10年时分别为6.8%和50.3%,P = 0.0003),而两组间肝失代偿的累积率(10年时分别为37.4%和51.7%)及生存率(10年时分别为53.8%和47.4%)无显著差异(Kaplan-Meir分析)。酒精性肝硬化患者的主要死亡原因是肝衰竭和非肝脏疾病,HCV感染所致肝硬化患者的主要死亡原因是HCC和肝衰竭。使用Cox比例风险模型进行的多因素分析显示,酒精性肝硬化患者发生HCC的风险低于HCV相关性肝硬化患者(风险比(HR),0.46),而肝失代偿和死亡风险相同。酒精性肝硬化患者生存降低的预测因素是未戒酒(HR,2.53),HCV感染所致肝硬化患者生存降低的预测因素是血清白蛋白水平低(1.58)。
酒精性肝硬化患者的生存率与HCV相关性肝硬化患者相似。酒精性肝硬化患者发生HCC的风险低于HCV相关性肝硬化患者。戒酒对提高酒精性肝硬化患者的生存率很重要。
