【摘要】:綜合分析幽門螺桿菌(Helicobacter pylori,HP)克拉霉素耐藥根除治療感染者的臨床效果。選取我院2014年10月~2015年10月擬對(duì)14C呼氣試驗(yàn)及快速尿素酶試驗(yàn)檢測(cè)均符合HP感染者32例,按照不同的治療方法隨機(jī)分為試驗(yàn)組與對(duì)照組,各16例。試驗(yàn)組將提取的胃粘膜組織采用實(shí)時(shí)定量熒光檢測(cè)法(Real time,PCR)進(jìn)行HP耐藥根除治療+患者CYP2C19基因型檢測(cè),依據(jù)不同的檢測(cè)結(jié)果,制定個(gè)體化的HP根除方案;對(duì)照組直接采用阿莫西林+克拉霉素+奧美拉唑治療。試驗(yàn)組的HP根除率為87.5%,對(duì)照組的HP根除率為68.75%,試驗(yàn)組的HP根除率顯著高于對(duì)照組(P0.05);本地區(qū)人群的CYP2C19對(duì)克拉霉素基因耐藥發(fā)生率為28.8%,HP的23S rRNA基因位點(diǎn)突變率(即HP對(duì)克拉霉素的耐藥發(fā)生率)為66.7%;根據(jù)CYP2C19基因型可分為UM(快代謝型)、IM(中間代謝型)、PM(弱代謝型);試驗(yàn)組的UM、IM、PM的HP根除率分別為55.11%、71.26%、92.32%,UM與PM的HP根除率比較差異較大(P0.05),UM與IM的HP根除率比較差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。試驗(yàn)組的HP根除率比較理想,HP的根除治療效果較為顯著。
[Abstract]:Objective: to analyze the clinical effect of Helicobacter pylori (Helicobacter pylori) clarithromycin resistance eradication in the treatment of infected patients. From October 2014 to October 2015, 32 patients with HP infection were selected for 14C breath test and rapid urease test. According to different treatment methods, 32 patients were randomly divided into two groups: the experimental group and the control group, each with 16 cases. In the experimental group, the extracted gastric mucosa tissues were detected by real time fluorescence assay (Real time PCR) to detect the CYP2C19 genotypes of patients with HP resistance eradication therapy. According to different test results, individualized HP eradication scheme was established. The control group was treated with amoxicillin clarithromycin omeprazole. The eradication rate of HP was 87.5 in the trial group and 68.75 in the control group. The eradication rate of HP in the experimental group was significantly higher than that in the control group (P0.05A), and the incidence of CYP2C19 resistance to clarithromycin gene in the local population was 28.8% of the 23s rRNA gene mutation rate (that is, HP). The incidence of drug resistance to clarithromycin was 66.7%; according to the genotype of CYP2C19, it could be divided into two groups: UM (fast metabolic type imm); the HP eradication rate of UMIMPM in the test group was 55.11%, 71.26% and 92.32%, respectively. The difference between HP eradication rate of UM and PM was significant (P0.05UM and IM). There was no significant difference in HP eradication rate between the two groups (P 0.05). The eradication rate of HP in the test group was better than that in the ideal group.
