SLA/LP 抗体及早期肝硬化表明自身免疫性肝炎患者的预后较差据发表于Hepatology的一项研究表明,18岁之前发现可溶性肝抗原/肝胰抗原抗体及肝硬化可认为是自身免疫性肝炎(AIH)短期及长期预后较差(包括整体的生存率较低)的危险因素。“虽然早期诊断配合最佳药物的应用可为AIH患者提供良好的预后,但是在某些情况下,这种疾病确是十分凶险的,” Arndt Vogel博士说道, “我们的研究探讨了

据发表于Hepatology的一项研究表明,18岁之前发现可溶性肝抗原/肝胰抗原抗体及肝硬化可认为是自身免疫性肝炎(AIH)短期及长期预后较差(包括整体的生存率较低)的危险因素。

“虽然早期诊断配合最佳药物的应用可为AIH患者提供良好的预后,但是在某些情况下,这种疾病却是十分凶险的,” Arndt Vogel博士说道, “我们的研究探讨了AIH患者缓解、复发及肝移植后的临床及遗传学特征。”


Vogel博士及其同事分析了2000年至2014年在汉诺威医学院接受治疗的264名AIH患者及399名非自身免疫性肝炎患者的DRB1等位基因。此外,还分析了人类白细胞抗原(HLA)。所有研究对象首次诊断时的平均年龄为39岁,75%为女性(n = 267),大部分为1型AIH(68%)。中位随访时间为10年,实际随访时间为1个月至40年不等。

结果发现,童年时期确诊的AIH患者其复发 (P =0.003)和肝移植(LT;P =0.014)的风险增加。同时这些患者的生存率也降低了(P < 0.001)。

首次诊断的患者中25%确诊为肝硬化,分析表明,肝硬化为生存率较低(P =0.003)及需进行肝移植(P =0.009)的不良预测因子。

与非AIH患者相比,更多的AIH患者其DRB1*03:01表型 (47.7% vs. 20.6%;P < 0.001),DRB1*04:01表型(28.4% vs. 14.8%; P < 0.001)为阳性。研究人员解释道,DRB1*04:01表型与较高的完全缓解率及较低的肝硬化率以及肝移植需求率有关(P = 0.024)。可溶性肝抗原/肝胰抗原(SLA/LP)抗体与较低的整体生存率(P = 0.037)及无需肝移植的存活率(P = 0.021)有关。

“童年时期确诊的AIH患者以及首次诊断为肝硬化或存在(SLA/LP)抗体其临床疗效较差的患者需要密切监控,” Vogel说道,“另一方面,DRB1*4:01表型阳性的患者其短期及长期的临床疗效较好,表明应将人类白细胞抗原分析以及SLA/LP抗体筛选纳入AIH常规的临床诊断之中。”
