Patients with <i>H. pylori</i> strain sensitive to tetracycline and metronidazole were assigned to bismuth quadruple therapy, including a proton pump inhibitor (PPI), bismuth, tetracycline, and metronidazole. Antibiotic resistance of <i>H. pylori</i> was analyzed by the Epsilometer test. Treatment efficacy was evaluated at 12 weeks based on <i>H. pylori</i> eradication and peptic ulcer healing rates. <i>H. pylori</i> infection status was evaluated by a ¹³C-urea breath test.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Most isolates showed extremely high rates of resistance to commonly prescribed antibiotics used for children, including clarithromycin (97.0%) and amoxicillin (84.6%), while the low rate of resistance to levofloxacin (16.2%). The overall success rate of eradication therapy in the intention-to-treat and the per-protocol group were 86.0% and 89.3%, respectively. Peptic ulcer healing rates for total patients at 6 weeks and 12 weeks were 75.0% and 97.7%, respectively. There were no entail unpleasant adverse events, and peptic ulcer symptoms decreased steadily over time in all cases.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>The bismuth quadruple therapy with a 2-week PPI pretreatment and followed by prolonged PPI was highly successful in eradicating <i>H. pylori</i> infection and healing ulcers in pediatric patients with active peptic ulcer. This might be preferable as a first-line empiric treatment regimen for <i>H. pylori</i>-positive pediatric patients with peptic ulcers, especially in populations with high rates of resistance to amoxicillin and clarithromycin.</p>\u0000 </section>\u0000 </div>","PeriodicalId":13223,"journal":{"name":"Helicobacter","volume":"29 6","pages":""},"PeriodicalIF":4.3,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142582950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients who developed map-like redness were older, had more severe intestinal metaplasia and nodularity and a higher total score on the Kyoto Classification of Gastritis both before and after eradication than patients who did not. On multivariate analysis, map-like redness was found to be associated with posttreatment intestinal metaplasia (odds ratio: 8.144; 95% CI: 2.811–23.592).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>In all patients who developed map-like redness after eradication, endoscopic intestinal metaplasia was observed at the site developed map-like redness before eradication therapy.
