【摘要】 目的 探讨诺氟沙星在根除幽门螺杆菌治疗中的疗效观察。方法 104例患者按病种随机分为两组, 对照组予标准“三联”疗法, 治疗组采用诺氟沙星三联疗法, 观察两组的HP根除率。结果 诺氟沙星治疗组HP根除率明显高于对照组(86.5% VS 63.5%) , 差异有统计学意义(P<0.05) 。结论 诺氟沙星三联疗法可以提高幽门螺杆菌的根除率。

【Abstract】 Objective To investigate the clinical effect of norfloxacin in the treatment of helicobacter pylori infection. Methods 104 patients were randomly divided into two groups according to disease,the norfloxacin streatment group and control group.The control group were treated with triple Hperadicational therapy and the treatment group were treated with norfloxacin triple Hp-eradicational therapy.The difference was compared between the two groups in the rate of Hp-eradication. Results Hp-eradication in the norfloxacin-treatment group was much higher than the controls (86.5% vs 63.5%), which had statistical difference(P<0.05). Conclusion The norfloxacin can effectively improve the rate of refractory Hp-eradication.

幽门螺杆菌(helicobacter pylori, HP)在全球自然人群的感染率超过50%, 且发展中国家高于发达国家。我国属发展中国家, 幽门螺杆菌感染率高。幽门螺杆菌感染是慢性胃炎、消化性溃疡等疾病的主要致病因素[1], 所以针对幽门螺杆菌治疗的研究已受到人们的广泛关注, 也是临床医生非常关注的临床问题。第三代喹诺酮类药物诺氟沙星(norfloxacin)治疗HP感染的相关报道甚少, 本研究旨在观察诺沙星三联疗法对HP的根治作用。
1 资料与方法
1. 1 一般资料 2009 年5月~2013年12月, 本院胃镜检查诊断为活动性胃、十二指肠溃疡、慢性非萎缩性胃炎患者共104人, 其中胃溃疡患者30人, 十二指肠溃疡34人, 慢性非萎缩性胃炎40人;男性55人, 女性49人;年龄为19~72岁。快速尿素酶试验、14C尿素呼气试验两项检查均为阳性者。排除患有肿瘤、息肉、严重肝肾疾病、妊娠、哺乳以及对药物有过敏者。
1. 2 方法
1. 2. 1 分组 104例患者中男性55例, 女性49例, 男女比例 1.1:1;年龄为 19~72 岁, 平均年龄为43岁。将患者随机分为治疗组和对照组, 各52 例。两组年龄、性别、病种差异无统计学意义(P>0.05)。
1. 2. 2 治疗方法 对照组予标准“三联”疗法:埃索美拉唑20 mg+阿莫西林1000 mg+克拉霉素500 mg, 2次/d, 疗程2周;治疗组采用诺氟沙星三联疗法:埃索美拉唑20 mg+阿莫西林1000 mg+诺氟沙星400 mg, 2次/d, 疗程2周。
1. 2. 3 疗效判定 治疗2周后做14C尿素呼气试验,若为阴性判定为HP根除成功。
1. 3 统计学方法 应用 SPSS 15.0 统计软件, 计数资料采用χ2检验, P<0.05 为差异有统计学意义。
2 结果
两组中胃溃疡患者均为15例(28.8%), 十二指肠溃疡患者均为17例(32.7%)。慢性非萎缩性胃炎患者均为20例(38.5%)。依据 HP 根除评定标准, 治疗组根治45例 (86.5%), 对照组根治33例(63.5%), 两组比较差异有统计学意义(P<0.05)。按病种分析胃溃疡患者在治疗组根治14例 (93.3%), 对照组根治9例(60.0%);十二指肠溃疡患者在治疗组根治15例 (88.2%), 对照组根治11例(64.7%);慢性非萎缩性胃炎患者在治疗组根治16例 (80.0%), 对照组根治13例(65.0%), 各病种之间两组比较均有统计学意义(P<0.05)。具体数据见表1。
3 讨论
自从19世纪80年代HP被发现以来, 发现HP不仅是很多胃、十二指肠疾病的致病因素, 还与口腔、皮肤、血液、心血管及呼吸系统乃至与妊娠及儿科等疾病的发生相关, 因此抗HP的治疗成为临床医生关注的课题。目前质子泵抑制剂加两种抗生素的三联疗法是全球推荐的根治HP的一线方案, 其根治率约为60%~80%, 各地差异较大, 且近期有下降的趋势, 本研究中对照组HP根治率为63.5%, 与报道相符。HP根除失败的主要原因是HP对常用抗生素耐药[2]。一项连续10年对常用抗生素的耐药研究显示:甲硝唑和克拉霉素耐药都呈逐渐上升的趋势[3], 且两者之间还存在交叉耐药, 寻找新的有效的治疗药物及方案是目前迫切需要解决的问题。endprint
诺氟沙星为第三代氟喹诺酮类抗菌药, 具有广谱抗菌作用, 尤其对需氧革兰阴性杆菌活性高, 诺氟沙星体外对多重耐药菌亦具抗菌活性。诺氟沙星为杀菌剂, 通过作用于细菌DNA螺旋酶的A亚单位, 抑制DNA的合成和复制而导致细菌死亡[4]。诺氟沙星口服吸收良好、血药浓度高、组织渗透性强、体内不易失活、不良反应少[5]。阿莫西林与诺氟沙星同属第一类杀菌剂, 它们之间联用呈协同作用[6], 因此本研究采用埃索美拉唑、阿莫西林和诺氟沙星三联疗法根除HP, 与对照组相比显著提高了HP根治率(86.5% VS 63.5%), 差异有统计学意义(P<0.05), 其中对于胃溃疡的患者, 采用诺氟沙星三联疗法根治率达93.3%, 显著高于对照组。
