IBD:托法替布治疗溃疡性结肠炎患者不会增加艰难梭菌感染的风险

2022-07-17 xuyihan MedSci原创

艰难梭菌一般指艰难梭状芽胞杆菌。 艰难梭菌(Clostridium difficile)对氧极为敏感,分离培养较困难.故命名为艰难梭菌。

研究表明,人群中艰难梭菌感染 (CDI) 的发病率正在增加,尤其是在患有炎症性肠病的人群中。炎症性肠病本身已被证明是 CDI 的独立危险因素。与非炎症性肠病患者的 CDI 相比,炎症性肠病患者的CDI造成的死亡率高达4.8倍。尽管生物制剂和小分子药物改善了溃疡性结肠炎 (UC) 的治疗,但这些治疗可能使患者更容易受到机会性感染。Tofacitinib 是一种口服小分子 Janus 激酶抑制剂,本项研究旨在评估托法替尼溃疡性结肠炎临床项目中艰难梭菌感染的发生率。

研究人员将来自4项随机、安慰剂对照研究的患者统一纳入本项研究分析中,所有患者接受了托法替布5或 10 mg 每天两次 [BID] 的治疗;所有收集的数据截至2020年8月24 日。最后评估了CDI的比例和发生率(每100患者年暴露事件数)。

整个队列包括1157名接受≥1剂5或10 mg BID 托法替布治疗的患者,总共收集到了2814.4 患者年的托法替尼暴露时间数据。共有82.6%的患者主要接受10 mg BID 的托法替布治疗。在诱导、维持和总体队列中,分别有 3 名(2 名托法替尼治疗,1 名安慰剂治疗)、3 名(所有安慰剂治疗)和 9 名患者出现了CDI感染;总体队列发病率为 0.31(95% 置信区间,0.14-0.59)。CDI 的严重程度均为轻度至中度,并在 8 名患者中得到有效治疗。9 名患者中有 6 名继续进行托法替尼治疗而没有中断。两名患者因住院而发生严重事件。发生 CDI 时,两名患者正在接受皮质类固醇治疗。

本项研究证实接受托法替布治疗的UC患者中出现 CDI并不常见,而且病例的严重程度为轻度至中度,大多数可以通过治疗得以解决。
