Abstract: 目的探讨将治疗前胃黏膜组织学特征作为幽门螺杆菌(Hp)阳性功能性消化不良(FD)患者根除Hp后症状改善疗效预测指标的可能性,以提高消化不良患者的治疗水平.方法连续调查240例进行胃镜检查Hp阳性FD患者,其中190例接受三联抗Hp治疗,另50例作为对照,给予奥美拉唑治疗,疗程均为7 d.治疗前胃黏膜组织学按新悉尼系统标准进行评估.治疗后1个月(治疗组和对照组)和6个月(治疗组)用C13-尿素呼气试验评估Hp.治疗前、治疗后1个月和6个月用消化不良调查表对症状程度进行评分,并计算仍有症状率,分析治疗前胃黏膜组织学与根除Hp后症状改善之间的相关性.结果Hp阳性FD患者分别有35.3%和42.6%在根除Hp后1个月和6个月消化不良症状改善显效,且根除Hp者症状缓解率显著高于Hp根除失败者(P<0.01);也高于对照组(P<0.01).治疗前胃黏膜组织学指标中,炎症、活动性程度和Hp密度在根除Hp后症状改善显效的FD患者均显著高于有效和无效者(P<0.05).多元回归分析支持上述组织学因素与根除Hp后症状显著改善相关.结论Hp阳性FD患者根除Hp后确实有部分患者症状显著改善.Hp阳性FD患者根除治疗前胃黏膜炎症、活动性程度和Hp密度能够预示根除Hp后症状改善的疗效.
