Gut:沃诺拉赞和阿莫西林双联治疗幽门螺杆菌的疗效分析

2020-03-12 MedSci原创 MedSci原创

由此可见,在克拉霉素耐药的地区,7天沃诺拉赞和低剂量阿莫西林双联治疗可获得满意的幽门螺杆菌根除率,且能取得与沃诺拉赞三联治疗相似的疗效。

迄今为止,还没有随机试验比较沃诺拉赞和阿莫西林双联治疗与其他标准方案在治疗幽门螺杆菌方面的疗效。近日,消化病领域权威杂志Gut上发表了一篇研究文章,该研究旨在评估沃诺拉赞和低剂量阿莫西林双联治疗7天作为幽门螺杆菌一线治疗的疗效,并与基于沃诺拉赞的三联疗法进行比较。

该前瞻性随机临床试验是在7家日本医疗机构进行的。幽门螺杆菌培养阳性且未接受过治疗的患者以1:1比例被随机分配VA-双联疗法(沃诺拉赞 20mg+阿莫西林750mg,两次/天)或VAC-三联疗法(沃诺拉赞 20mg+阿莫西林 750mg+克拉霉素200mg 两次/天)治疗7天,并根据年龄、性别、幽门螺杆菌抗菌素耐药性和医疗机构进行分层。治疗结束后至少4周采用13c-尿素呼气试验来评估根除是否成功。

在2018年10月至2019年6月期间,629名受试者进行了筛查,335名受试者进行了随机分组。意向治疗分析VA-双联治疗和VAC-三联治疗的根除率分别为84.5%和89.2% (p=0.203),根据协议分析的根除率分别为87.1%和90.2% (p=0.372)。在根据协议的分析中,VA-双联治疗的疗效并不比VAC-三联治疗差。VA-双联治疗对克拉霉素耐药菌株的根除率明显高于VAC-三联治疗(92.3% vs 76.2%;p=0.048)。不良事件的发生率在组间是相等的。

由此可见,在克拉霉素耐药的地区,7天沃诺拉赞和低剂量阿莫西林双联治疗可获得满意的幽门螺杆菌根除率,且能取得与沃诺拉赞三联治疗相似的疗效。
