Bismuth-containing quadruple therapies (BcQTs) have been proposed as a viable treatment option; however, the optimal duration for it remains contentious. This systematic review and meta-analysis aimed to compare the clinical efficacy of short-term BcQT (defined as 7 or 10 days) with a standard 14-day course.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;A systematic search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted for randomized controlled trials published in English until June 20, 2024. Eligibility criteria were applied to identify relevant studies. Summary risk ratios (RRs) and 95% confidence intervals (CIs) were calculated for the included studies regarding eradication rates, adverse effects, and compliance. This systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and was previously registered in PROSPERO under registration number CRD42024547773.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;This meta-analysis finally included 15 trials involving a total of 4505 patients. The eradication rates for short courses of BcQT were lower than those for the 14-day course (RR 0.96, 95% CI 0.93–0.99). However, the eradication rate for the 10-day therapy was comparable to that of the 14-day therapy (RR 0.98, 95% CI 0.95–1.00). Subgroup analyses of antibiotic combinations indicated that tetracycline and metronidazole combinations yielded similar &lt;i&gt;H. pylori&lt;/i&gt; eradication rates in the 7-day versus the 14-day BcQT (RR 0.93, 95% CI 0.84–1.02). In the potassium-competitive acid blocker subgroup, the eradication rates remained similar across the 14-day group and the short-course treatment groups, whether evaluating the short-term treatment groups as a whole or the 7- and 10-day subgroups separately. Additionally, the adverse effects and compliance associated with the short course of BcQT were comparable to those of the 14-day therapy.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusion&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;A 10-day course of BcQT may represent the optimal treatment duration.

All patients in the registry who were treated with CBS between the period 2020 and 2023 were included in this study. The primary outcome was the eradication rate, which was assessed using a <sup>13</sup>C-urea breath test or monoclonal antigen in the stool 6–8 weeks post-treatment.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>The registry included 682 patients, 38 (5.6%) of whom underwent treatment with CBS. Fifty percent (19/38) of patients had previously undergone unsuccessful eradication treatment. In 78.9% (30/38) of patients, treatment was guided by an antibiotic sensitivity test. In the remaining patients, an empirical approach was employed. The CBS therapies used were as follows: quadruple therapy with proton pump inhibitors (PPIs), CBS, amoxicillin, and metronidazole (MET) [18/38 (47.3%)]; quadruple therapy with PPIs, CBS, tetracycline, and MET [13/38 (34.2%)]; and other therapies [7/38 (18.4%)]. Thirty-two patients (84.2%) treated with CBS were followed-up with eradication monitoring. The overall eradication rate in patients treated with CBS was 93.8% (30/32, [95% CI: 85.4%–100%]), whereas it was 86.7% in patients in the registry who were not on CBS treatment (430/496, [95% CI: 83.3%–89.5%], <i>p</i> = 0.208). In the six patients with dual resistance to clarithromycin (CLA) and MET who were treated with quadruple therapy with CBS, the eradication rate was 100% (<i>n</i> = 6/6, [95% CI: 61.0%–100%]).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusion</h3>\u0000 \u0000 <p>CBS therapies in our registry, although only used in selected cases and at lower than recommended levels, were very effective and showed an eradication rate of &gt; 90%.</p>\u0000 </section>\u0000 </div>","PeriodicalId":13223,"journal":{"name":"Helicobacter","volume":null,"pages":null},"PeriodicalIF":4.3,"publicationDate":"2024-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142390222","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}
