BMJ:5日青霉素V疗法治疗A群链球菌咽扁桃体炎

2019-10-05 MedSci MedSci原创

研究认为,对于A群链球菌所致咽扁桃体炎患者,每日4次,共5天的青霉素V疗效不低于每日3次,共10天疗法。两组患者复发率及并发症发生率无显著性差异。

近日研究人员考察了降低青霉素V总量对治疗A群链球菌引起的咽扁桃体炎的影响。


研究于2015-18年间,在17个医疗中心开展。6岁及以上由A群链球菌引起的咽扁桃体炎患者参与,符合3-4个Centor标准(发热≥38.5°C,淋巴结变软,扁桃体覆盖,无咳嗽)。患者接受青霉素v 800 mg,每日4次,连续5天(共16g),而目前推荐剂量为1000 mg,每日三次,共10天(共30g)。研究的主要终点为抗生素治疗结束后5-7天临床治愈。次要结果包括细菌根除、症状缓解时间、复发频率、并发症和新扁桃体炎以及不良事件的类型。


433名患者参与研究,其中215人接受5天治疗,218人接受10天治疗。5日组临床治愈率为89.6% (n=181/202),而10天组为93.3% (n=182/195)。5日组细菌根除率为80.4%(n=156/194) ,10日组为90.7% (n=165/182)。5和10日组分别有8和7名患者复发,0以及4名患者出现并发症,6和13名患者出现新扁桃体炎。5天组症状缓解时间缩短。不良反应主要为腹泻、恶心和外阴阴道紊乱;10天组不良事件发生率较高,持续时间较长。


研究认为,对于A群链球菌所致咽扁桃体炎患者,每日4次,共5天的青霉素V疗效不低于每日3次,共10天疗法。两组患者复发率及并发症发生率无显著性差异。
