我们可能笼统的知道,当感染了乙肝病毒(HBV)后,容易进展为肝炎、肝硬化、肝细胞癌,并且最终可能死于上述原因,但HBV相关的死亡率具体有多少并不清楚,来自法国的一项研究回答了上述问题。这项研究发表在近期的Journal of Hepatology上。

他们通过一项以人群为基础的队列研究来调查慢乙肝患者较普通人群死亡风险有多大,并且区分所有原因死亡率和HBV相关死亡率的风险因素。

方法

一个专业的以人群为基础的登记中心记录了自1994年以来法国100万居民的慢性乙肝病毒感染情况。通过这些记录的数据计算所有原因死亡的死亡率和HBV相关的死亡率。使用Kaplan - Meier法计算累积死亡率。用Cox模型进行多因素分析。

结果

从1994年到2009年,共有1117人被诊断为慢性HBV感染,其中有136(12.2%)人死亡。在HBV感染人群中死亡率是较高的(SMR 1.7 [1.4-2.0]),所有死亡原因中,以肝细胞癌、非霍奇金淋巴瘤、肝病所占的比例最高,分别为(SMR 8.6 [3.1-18.6])、(SMR 8.6 [3.1-18.6])、(SMR 10.2 [5.8-16.6])。在所有死亡原因中,5年累积死亡率为8.6% ,10年累积死亡率为12.6%,15年累积死亡率为18.5%,对应的HBV相关的死亡率分别为3.5%, 4.2% 和5.8%。多因素分析显示,男性、被诊断时的年龄大于45岁、酗酒、医源性风险等因素是死亡率增加的预测因素。  

结论    

这项研究揭示了HBsAg阳性患者的死亡率增加了,并且在所有死亡原因中,肝病、肝细胞癌和非霍奇金淋巴瘤占了很大一部分比例。
