Clin Gastroenterology H: 自身免疫性肝炎患者的死亡率风险明显增加

2020-10-15 MedSci原创 MedSci原创

自身免疫性肝炎(AIH)是一种慢性炎症性肝病,最终可能会导致肝硬化和肝衰竭的发生,但目前关于AIH总体死亡率的数据存在矛盾。本项研究旨在探究AIH对于死亡率的影响。

背景和目标

自身免疫性肝炎(AIH)是一种慢性炎症性肝病,最终可能会导致肝硬化和肝衰竭的发生,但目前关于AIH总体死亡率的数据存在矛盾。本项研究旨在探究AIH对于死亡率的影响。

 

方法

这是1969年至2017年在瑞典进行的一项基于全国人群的队列研究,研究对象为6016名AIH成人患者和28146名匹配的普通人群对照人员。通过Cox回归,研究人员估算了整体死亡和特定原因死亡的危险比(HRs)。肝移植也被认为是主要的观察结果。

 

结果

在随访期间,有3185例AIH死亡病例的出现(41.4 / 1000人年),而对照人群中出现10477例死亡病例(21.9 / 1000人年)。AIH个体的10年累积死亡发生率为32.3%(95%CI = 31.1-33.6),对照人群为14.1%(95%CI = 13.7-14.5)。活检有肝硬化的AIH患者有较高的死亡风险(HR = 4.55; 95%CI = 3.95-5.25),而纤维化,无纤维化炎症或坏死的患者死亡率无差异。门脉高压和胆汁淤积性肝病重叠也与死亡有关。AIH与血管疾病(HR = 1.27; 95%CI = 1.15-1.40),肝病(HR = 66.24; 95%CI = 48.19-91.03)和肝外恶性肿瘤(HR = 1.69; 95%CI = 1.51-1.89)的死亡风险增加相关。总而言之,AIH个人的死亡风险仍然更高。

 

 

结论

AIH与死亡风险升高2倍有关。肝硬化,门静脉高压症和胆汁淤积性肝病重叠患者的死亡风险更高。
