摘要
研究背景:幽门螺杆菌(Helicobacter pylori, H.pylori, HP)与慢性胃炎、消化性溃疡、胃癌等疾病密切相关。深入探讨本地区HP根除现状将十分有助于指导临床工作。建立新型高效廉价的一线标准治疗方案是临床工作的当务之急。 研究目的:通过临床回顾性的观察性研究,统计不同疾病状态、不同病理类型、不同质子泵抑制剂(PPI)种类、不同抗生素组合的10天含铋剂四联方案对幽门螺杆菌根除疗效及分析其社会经济价值,揭示本地区HP对常用抗生素的敏感性,提出最有效最经济的根除方案。 研究方法:287例于2012年7月至2013年1月在浙江大学医学院附属第二医院门诊就诊使用10天含铋剂四联方案治疗的HP感染相关性消化性溃疡或慢性胃炎初治者纳入回顾性观察研究,其中消化性溃疡病73例,其具体分组如下:A组:埃索美拉唑20mg+呋喃唑酮0.1g+阿莫西林1g+果胶铋0.2g;B组:兰索拉唑30mg+呋喃唑酮0.1g+阿莫西林1g+果胶铋0.2g;C组:埃索美拉唑20mg+克拉霉素0.5g+阿莫西林1g+果胶铋0.2g;D组:埃索美拉唑20mg+克拉霉素0.5g+呋喃唑酮0.1g+果胶铋0.2g,以上药物早晚各服用1次,疗程为10天。疗程结束至少4周后采用13C或14C尿素呼气试验评估疗效。按意向治疗(ITT)分析和按治疗方案(PP)分析统计根治率,并计算成本效果比。 研究结果:慢性胃炎和消化性溃疡患者的HP根除率分别为81.5%(154/189)、75.8%(47/62),无显著性差异(P>0.05);病理示慢性黏膜炎、萎缩、肠化的患者的HP根除率分别为78.7%(144/183)、92.3%(36/39)、72.4%(21/29),萎缩组的HP根除率明显高于其他两种病理类型,具有统计学意义(P<0.05);4种四联方案的HP根除率分别为83.1%(69/83)、74.4%(32/43)、84.1%(53/63)、75.8%(47/62),无显著性差异(P>0.05),其成本-效果比分别为4.23、5.22、8.17、8.35。研究结论:慢性胃炎和消化性溃疡病患者的HP根除率无显著性差异。病理类型示萎缩性的HP根除率明显高于慢性黏膜炎和肠化病人。含埃索美拉唑或兰索拉唑的四联方案,呋喃唑酮、阿莫西林、克拉霉素两两组合抗生素的四联方案的HP根除率均无明显差异。但是含埃索美拉唑、阿莫西林、呋喃唑酮、果胶铋的10天四联方案医疗成本低,更适合临床大范围推广。
