BMJ:女性复发性尿路感染预防性抗生素的替代治疗

2022-03-12 MedSci原创 MedSci原创

该试验报道了日常抗生素预防的非劣效性,根据患者偏好和抗生素管理倡议,采用非抗生素的马尿酸甲氧胺预防性治疗可能适合有尿路感染反复发作病史的女性。

近日,顶级杂志BMJ上发表了一篇研究文章,研究人员旨在评估马尿酸甲氧胺预防复发性尿路感染的疗效,并与目前每日低剂量抗生素的标准预防措施进行比较。

该研究为多中心、开放标签、随机、非劣效性试验。本研究是于2016年6月至2018年6月期间英国8个中心中完成的。参与者为年龄18岁以上且需要预防性治疗的复发性尿路感染女性。受试者随机分配(1:1)接受抗生素预防或马尿酸甲氧胺治疗12个月。治疗分配没有实施盲法,并且允许在组间进行交叉。

该研究的主要结局指标为治疗期间有症状的、需抗生素治疗、尿路感染的绝对差异。患者和公众参与小组将非劣效性界值定义为每人每年一次尿路感染。在改良意向治疗人群中进行的分析纳入了观察至少六个月的所有参与者。

参与者被随机分配到抗生素预防组(n=120)或甲氧胺马尿酸盐组(n=120)。修改后的意向治疗分析纳入了205名(85%)参与者(抗生素,n=102(85%);甲氧胺马尿酸盐,n=103(86%))。在12个月的治疗期间,抗生素治疗的尿路感染发生率为每人每年0.89人次(95%置信区间为0.65至1.12),抗生素组为1.38(1.05至1.72),绝对差异为0.49(90%置信区间0.15至0.84),确认存在非劣效性。抗生素组34/142(24%)和甲氧胺组35/127(28%)报告了不良反应,大多数反应是轻微的。

由此可见,该试验报道了日常抗生素预防的非劣效性,根据患者偏好和抗生素管理倡议,采用非抗生素的马尿酸甲氧胺预防性治疗可能适合有尿路感染反复发作病史的女性。
