Infection: 甲硝唑也可以治疗非重症艰难梭菌感染

2022-08-17 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。

艰难梭菌感染 (CDI) 是抗生素相关性腹泻的主要感染原因,与死亡率和发病率有关。CDI 的复发率在10%到30%不等,具体取决于患者的因素,如年龄和免疫状态。2000年 BI/NAP1/027菌株的出现导致全球CDI患病率增加,而CDI对治疗的反应性降低,从历史上看,甲硝唑是首发非严重CDI的推荐治疗方法。尽管证据参差不齐,但一些早期的临床试验数据表明,甲硝唑和万古霉素可能导致相似的复发率。然而,几项新试验显示万古霉素优于甲硝唑,这导致美国传染病学会 (IDSA) 在 2017 年推荐口服万古霉素作为非严重首发 CDI 的一线治疗。在这项研究中,研究人员假设甲硝唑与万古霉素相比在需要住院治疗的复发率和死亡率方面具有相似的疗效并进行了相关研究。

本项研究是一项单中心回顾性队列研究,纳入了在2015年至2020年之间住院的首次患有非严重CDI的成年患者,并使用甲硝唑或万古霉素作为单药治疗至少10天。最后评估了需要住院治疗的 CDI 复发(主要结果)和出院后长达 8 周的全因死亡率。

研究结果显示160名患者接受了万古霉素治疗,149名患者接受了甲硝唑治疗。万古霉素组10例(6.2%)患者因CDI复发在8周内再次住院,甲硝唑组有13例(8.7%)(P=0.407)。甲硝唑组39例(26.2%)和万古霉素组46例(28.8%)在8周内出现死亡(P=0.61)。在调整了年龄、性别、缺血性心脏病、白细胞计数、中性粒细胞计数和 CRP 后,两种治疗之间没有显着差异(CDI 导致的8周内再次住院P=0.5059;院内死亡P=0.7950;4周死亡率P=0.2988;8 周死亡率P=0.8237).

本项研究证实与万古霉素相比,使用甲硝唑在需要住院、住院的复发率以及非严重首发 CDI 的4周和8周死亡率方面并不差。
