Liver Int:慢性乙型肝炎患者血清丙氨酸氨基转移酶水平及肝脏疾病相关死亡率的关系

2018-02-01 MedSci MedSci原创

肝脏疾病相关的死亡率显著增加,即使在血清ALT水平较低的CHB患者中。对于年龄>40岁以上,且ALT高于正常值上限的患者,应仔细监测或进行早期抗病毒治疗。

血清丙氨酸氨基转移酶(ALT)已被用于识别需要抗病毒治疗的慢性乙型肝炎患者。然而,目前并不清楚ALT与肝脏疾病相关的死亡率增加的关系。

本研究采用了韩国国民健康保险服务的健康检查队列,其中包括大约50万40-79岁的人。本研究共纳入12486例慢性乙型肝炎患者,同时这些患者无其他肝病;患者的肝脏疾病相关死亡,包括因肝癌引起的死亡,被调查了9年。

血清ALT水平与肝脏相关死亡率呈正相关。在男性患者中,血清ALT水平分别为<20, 20-29, 30-39, 40-49, 50-79,和≥80 U/L时,肝脏疾病相关死亡率分别为0.14, 0.17, 0.24, 0.57, 0.63, and 0.85/100人-年(%);在女性肝脏疾病相关死亡率分为0.03%, 0.09%, 0.12%, 0.63%, 0.65%, 和0.32%。血清ALT水平处于40-79 U/L时,男性和女性肝脏疾病相关死亡率分别为0.60%和0.64%,这个比率与性别、年龄匹配的非慢性乙型肝炎患者整体死亡率相似。与肝脏相关的死亡率预测的最佳的临界值为男性血清ALT水平>34 U/L和女性血清ALT水平>30 U/L。

肝脏疾病相关的死亡率显著增加,即使在血清ALT水平较低的CHB患者中。对于年龄>40岁以上,且ALT高于正常值上限的患者,应仔细监测或进行早期抗病毒治疗。
