雷尼替丁加抗生素三联治疗十二指肠溃疡的疗效观察
治疗十二指肠溃疡55倒,观察。其近期愈合率及复发率。对象与方法将内镜确诊无并发症的活动性十二指肠溃疡,随机分成治疗组55例和对照组54例治疗组:服用国产甲硝唑0.2g,每天3次,羟氨苄青霉素0.5g,每天3次,国产雷尼替丁0.15g,每天2次对照组:单服国产雷尼替丁0.15g,每天2次。羟氨苄青霉素、甲硝唑连续服用两周,雷尼替丁服四周对溃疡愈合者采用“症状自我控制疗法”进行随访治疗。同时采用尿素酶检测法观察两组HP的清除率结果一、溃疡愈合率治疗组溃疡愈合率为92.7%(51/55")明显高于对照组的68.5(38/54),P<0.05。二、幽门螺杆菌(HP)清除率治疗前治疗组与对照组的HP阳性率分别为96、4(53/55)和90.7(49/54),两组间无差异。治疗后其HP清除率分别为86.8(46/53)、10、2(5/49),两组间差异非常显著(P<0、01)。三、胃窦活动性炎症消失率治疗组为7O.2(43/55),显著高于对照组的22、2(12/54),P<O、05四、副作用治疗组7倒出现恶心,厌食,1倒出现血AST升高。对照组l例血AST升高五、年累积复发率随访治疗满一年者,治疗组38例中复发7倒,占18.4对照组34例中复发16例,占47.6差异显著(P<O.05)。二组中复发病例均为HP未清除者,检测仍为HP阳性讨论近年来研究表明,幽门螺杆菌(HP)与十二指肠溃疡(DU)密切相关,根除HP有利于溃疡愈合,并可明显减少溃疡复发。我们用羟氨苄青霉素、甲硝唑加雷尼替丁联合治疗DU,4周愈合率92.7,明显高于单用雷尼替丁的68.5其原因可能与两种药物能产生如下协调作用有关:①抑制胃酸分泌;②清除或抑制HP;⑧改善胃窦部炎症对溃疡愈合后的患者,采用长期维持用药防止复发,但患者依从性差,不易坚持我们采用“症状自我控制疗法”进行追踪治疗,明显地降低了DU的复发率,特别是联合用药组使溃疡年累积复发率降至18、4。联合用药组溃疡复发率低,与羟氨苄青霉素加甲硝唑有杀抑HP及改善炎性病变的作用有关,尤其是羟氨苄青霉素,能提高胃肠粘膜内前列腺素E。水平,改善愈合质量及增强抗损伤能力。该法疗程短,仅在出现症状时服药,症状消失一周后即停药,可脐低费用,依从性好,付作用少,值得推作者单拄:563002贵州省道义地区医院
