摘要 目的:观察兰索拉唑对十二指肠溃疡愈合及幽门螺杆菌(H pylori)的清除作用,并比较兰索拉唑、奥美拉唑及泰胃美对离体培养的H pylori生长的作用. 方法:经胃镜检查,确诊为H pylori阳性的十二指肠溃疡患者65例,给予兰索拉唑30 mg/次,1次/d,服药1 mo, 溃疡愈合后,改为15 mg/次,1次/d,维持治疗3 mo. 服药1 mo及维持治疗3 mo,复查胃镜了解十二指肠溃疡的愈合情况,胃黏膜组织学W-S染色检查H pylori取培养好的CAPMN66 H pylori标准菌株,涂入不同药物浓度的培养皿内,在37℃微氧环境下培养3—5 d,确定兰索拉唑、奥美拉唑和泰胃美的最小抑菌浓度(MIC). 结果:兰索拉唑治疗1 mo后,十二指肠溃疡愈合率为93.3% (56/60),胃酸和胃蛋白酶分泌减少,与治疗前比较有明显差异(107.5±11.2 mEq/L vs 43.3±3.2 mEq/L,P<0.05 和910.8±194.3 mg/L vs 488.2±265.0 mg/L,P<0.01).兰索拉唑治疗后H pylori检出率下降,治疗前胃窦部H pylori 检出率为96%,治疗1 mo后为64%,36%的患者胃窦部H pylori已清除,胃底体部H pylori检出率在治疗前后变化不大.给药1 mo和3 mo后,胃窦部H pylori的感染程度明显减轻,清除的比例明显增加,治疗前为3%,治疗后1 mo为36%,3 mo为22%,胃底体部H pylori的感染程度也减轻.兰索拉唑和奥美拉唑抑制离体培养的H pylori生长,兰索拉唑MIC为12.5 mg/L,奥美拉唑是50 mg/L, 泰胃美MIC>1 600 mg/L. 结论:兰索拉唑促进H pylori阳性的十二指肠球溃疡愈合, 抑制胃酸和胃蛋白酶分泌,而且能清除H pylori,对胃窦部的作用更明显.兰索拉唑和奥美拉唑抑制离体培养的H pylori 的生长,前者作用强于后者.未观察到泰胃美有抑制H pylori 生长的作用.
