目的:了解广东省梅州地区幽门螺杆菌( Hp)感染标准三联治疗的根除率及对甲硝唑、克拉霉素、阿莫西林及左氧氟沙星耐药情况,寻找Hp未根除的最佳补救治疗措施。方法将2011年4月至2013年3月因胃肠道症状于胃镜室检查的297例Hp阳性患者按照就诊顺序号随机分为三个初治组:A组( OCA组)、B组( OCM组)和C组( OCL组),统计Hp根除率,所有初次治疗失败者均纳入D组( OBAL组),统一给予四联( PPl+B+A+L)7 d疗法,统计Hp根除率。对297例初次根除治疗和87例再次根除治疗的患者进行Hp体外分离培养,并且对临床成功分离的230株Hp进行药敏试验,采用E-test法测定甲硝唑、克拉霉素、阿莫西林及左氧氟沙星4种常用抗生素对Hp菌株的最小抑菌浓度( MIC值),了解临床Hp对4种抗生素的耐药情况。结果 A组( OCA组)、B组( OCM组)和C组( OCL组)三个初治组Hp根除率意向性分析( ITT分析)分别为72.0%(72/100)、63.0%(63/100)、72.2%(70/97),符合方案数据分析(PP分析)分别为72.7%(72/99)、64.3%(63/98)、73.7%(70/95),初治三组间根除率差异无统计学意义(ITT分析P=0.278,PP分析P=0.288,P>0.05)。复治D组(OBAL组)Hp根除率ITT分析为92.0%(80/87),符合PP分析为97.6%(80/82),明显高于初治三组(ITT分析P=0.000,PP分析P=0.000)。230株临床分离Hp菌株中对左氧氟沙星、阿莫西林、克拉霉素和甲硝唑的耐药率分别为6.08%(14/230)、6.52%(15/230)、25.65%(59/230)、70.87%(163/230),其中37株为混合耐药,多重耐药率达16.09%(37/230)。甲硝唑耐药率明显高于左氧氟沙星、阿莫西林和克拉霉素(P=0.000),克拉霉素耐药率明显高于左氧氟沙星和阿莫西林(P=0.000),阿莫西林与左氧氟沙星耐药率差异无统计学意义(P=0.848)。结论广东省梅州地区Hp耐药情况与全国平均水平相似,标准三联的根除率低于80%,含铋剂的四联疗法是较好的补救治疗措施。
目的:瞭解廣東省梅州地區幽門螺桿菌( Hp)感染標準三聯治療的根除率及對甲硝唑、剋拉黴素、阿莫西林及左氧氟沙星耐藥情況,尋找Hp未根除的最佳補救治療措施。方法將2011年4月至2013年3月因胃腸道癥狀于胃鏡室檢查的297例Hp暘性患者按照就診順序號隨機分為三箇初治組:A組( OCA組)、B組( OCM組)和C組( OCL組),統計Hp根除率,所有初次治療失敗者均納入D組( OBAL組),統一給予四聯( PPl+B+A+L)7 d療法,統計Hp根除率。對297例初次根除治療和87例再次根除治療的患者進行Hp體外分離培養,併且對臨床成功分離的230株Hp進行藥敏試驗,採用E-test法測定甲硝唑、剋拉黴素、阿莫西林及左氧氟沙星4種常用抗生素對Hp菌株的最小抑菌濃度( MIC值),瞭解臨床Hp對4種抗生素的耐藥情況。結果 A組( OCA組)、B組( OCM組)和C組( OCL組)三箇初治組Hp根除率意嚮性分析( ITT分析)分彆為72.0%(72/100)、63.0%(63/100)、72.2%(70/97),符閤方案數據分析(PP分析)分彆為72.7%(72/99)、64.3%(63/98)、73.7%(70/95),初治三組間根除率差異無統計學意義(ITT分析P=0.278,PP分析P=0.288,P>0.05)。複治D組(OBAL組)Hp根除率ITT分析為92.0%(80/87),符閤PP分析為97.6%(80/82),明顯高于初治三組(ITT分析P=0.000,PP分析P=0.000)。230株臨床分離Hp菌株中對左氧氟沙星、阿莫西林、剋拉黴素和甲硝唑的耐藥率分彆為6.08%(14/230)、6.52%(15/230)、25.65%(59/230)、70.87%(163/230),其中37株為混閤耐藥,多重耐藥率達16.09%(37/230)。甲硝唑耐藥率明顯高于左氧氟沙星、阿莫西林和剋拉黴素(P=0.000),剋拉黴素耐藥率明顯高于左氧氟沙星和阿莫西林(P=0.000),阿莫西林與左氧氟沙星耐藥率差異無統計學意義(P=0.848)。結論廣東省梅州地區Hp耐藥情況與全國平均水平相似,標準三聯的根除率低于80%,含鉍劑的四聯療法是較好的補救治療措施。

Objective To understand the Helicobacter pylori ( Hp) infection eradication rate of standard tri-ple therapy in Guangdong Meizhou and the drug resistance situation for metronidazole ,clarithromycin ,amoxicillin and levofloxacin ,in order to look for the treatment countermeasures in Hp eradication failure .Methods 297 cases of Hp positive patients because of gastrointestinal symptoms to our hospital examined from April 2011 and March 2013,were randomly assigned into three standard triple therapy groups:A ( OCA ) group and B ( OCM ) group and C ( OCL ) group.The Hp eradication rate was analyzed .Patients with primary treatment failure were selected as group D (OBAL),proceed to (PPl+B+A+L)7 d therapy,the Hp eradication rate was analyzed .230 Hp strains were isola-ted and cultured from 297 cases received the first eradication therapy and 87 cases received again eradication therapy . The minimum inhibitory concentration (MIC) of metronidazole,clarithromycin,amoxicillin and levofloxacin were tested by E-test,in order to determine the resistance of these four antibiotics in clinical isolated Hp strains .Results With intention-to-treat(ITT) analysis,the Hp eradication rates of group A (OCA),group B(OCM) and group C(OCL) were 72.0%(72/100),63.0%(63/100) and 72.2%(70/97),respectively.With per-protocol(PP) analysis,the Hp eradication rates of group A (OCA),group B(OCM) and group C(OCL) were 72.7%(72/99),64.3%(63/98),73.7%(70/95),respectively.The eradication rate among three standard triple therapy groups had no obvi-ous difference (ITT:P=0.278,PP:P=0.288,P>0.05).With ITT analysis,the Hp eradication rate in the quadrup-le therapy group D(OBAL) was 92.0%(80/87).With per-protocol(PP) analysis,the Hp eradication rate in the quadruple therapy group D(OBAL) was 97.6%(80/82),which was higher than that of the three standard triple ther-apy groups(ITT:P=0.000,PP:P=0.000).In 230 clinical isolated Hp strains,the resistant rates of levofloxacin,amoxicillin,clarithromycin and metronidazole were 6.08%(14/230),6.52%(15/230),25.65%(59/230), 70.87%(163/230),respectively.Of those 37 strains were mixed resistance,the mixed resistant rate was 16.09%(37/230).The resistant rate of metronidazole was higher than levofloxacin , amoxicillin and clarithromycin ( P =0.000,P<0.01),the resistant rate of clarithromycin was higher than levofloxacin and amoxicillin (P=0.000),no statistically significant difference between amoxicillin and levofloxacin (P=0.848).Conclusion The Hp resistance is similar to the national average in Guangdong Meizhou ,the eradication rate of standard triple therapy is lower than 80%,contain bismuth agent of quadruple therapy is good rescue therapy .
