JAMA:CRP指导、7天或14天抗生素方案用于治疗革兰氏阴性菌血症

2020-06-03 MedSci原创 MedSci原创

对于革兰氏阴性菌血症的成人患者,CRP指导的抗生素治疗方案、7天治疗方案与14天治疗方案相比,30天临床疗效无显著差异

抗生素过度使用会导致抗生素耐药性, 革兰氏阴性菌血症是一种常见的感染需使用大量的抗生素。近日研究人员比较了C反应蛋白(CRP)指导抗生素治疗 vs7或14天抗生素持续治疗对患者30、60和90天临床预后的影响。
 
研究在瑞士开展,革兰氏阴性菌血症成人住院患者参与,随机接受CRP指导的抗生素治疗持续时间(CRP从峰值下降75%后停止治疗;n=170)、固定的7天治疗持续时间(n=169)或固定的14天治疗持续时间(n=165)。研究的主要结果是第30天的临床失败率,定义为复发性菌血症、局部化脓性并发症、远端并发症、临床恶化或死亡、重新开始革兰阴性的抗生素治疗。次要结果包括随访第90天的临床失败率。
 
在504名患者中(平均年龄79岁,61%为女性),493名(98%)完成30天随访,448名(89%)完成90天随访。CRP组中位抗生素持续时间为7天。主要事件发生情况如下:CRP组164名患者中的4名(2.4%),7天组166名患者中的11名(6.6%),14天组163名患者中的9名(5.5%)(CRP组vs14天组:-3.1%;7天vs14天组的:1.1%)。到第90天,CRP组143名患者中有10名(7.0%)出现临床治疗失败,7天组151名患者中有16名(10.6%)出现临床失败,14天组153名患者中有16名(10.5%)出现临床失败。
 
研究认为,对于革兰氏阴性菌血症的成人患者,CRP指导的抗生素治疗方案、7天治疗方案与14天治疗方案相比,30天临床疗效无显著差异。
