Gastroenterology:炎症性肠病用药过程中机会性感染的风险分析

2018-08-31 MedSci MedSci原创

炎症性肠病的患者在使用肿瘤坏死因子拮抗剂(抗TNF)和硫嘌呤(联合治疗)时与之相关的感染风险尚不明确。研究人员评估了在大量患者中使用硫嘌呤单一疗法,抗TNF单一疗法或联合疗法治疗的炎症性肠病(IBD)患者严重和机会性感染的风险的情况。

背景与目的
炎症性肠病的患者在使用肿瘤坏死因子拮抗剂(抗TNF)和硫嘌呤(联合治疗)时与之相关的感染风险尚不明确。研究人员评估了使用硫嘌呤单一疗法,抗TNF单一疗法或联合疗法治疗的炎症性肠病(IBD)患者严重和机会性感染的风险的情况。

方法
研究人员在法国国家健康保险数据库中对诊断为IBD的患者(18岁或以上)进行了全国性的回顾性研究;研究数据来自于从2009年1月1日至2014年12月31日间。使用针对基线和时间调整的边际结构Cox比例风险模型,比较了联合治疗,抗TNF和硫嘌呤单一疗法引起的严重和机会性感染的风险。

结果
本项研究纳入了190694名IBD患者,随访期间发生了8561例严重感染和674例机会性感染。与抗TNF单药治疗相比,联合治疗与严重感染风险增加相关([HR]:1.23; 95%[CI]:1.05-1.45)和机会性感染(HR:1.96; 95%CI: 1.32-2.91)。与硫嘌呤单药治疗相比,抗TNF单药治疗与严重感染风险增加相关(HR:1.71; 95%CI:1.56-1.88),分枝杆菌感染(HR:1.98; 95%CI:1.15-3.40)和细菌感染(HR:2.38; 95%CI:1.23-4.58)。相反,与硫嘌呤单一疗法相比,抗TNF单一疗法与机会性病毒感染的风险降低相关(HR:0.57; 95%CI:0.38-0.87)。

结论
在这一项对法国IBD患者的全国性队列研究调查中,研究人员发现接受免疫抑制治疗的患者存在严重和机会性感染风险。
