Background/Aims: Fluoroquinolone-containing triple eradication therapy could be considered an alternative regimen for the second- line treatment of <i>Helicobacter pylori</i> infection. This study aimed to investigate the changes in the eradication efficacy of fluoroquinolone- containing triple therapy from 2003 to 2018 in Korea.Materials and Methods: Patients with a history of first-line eradication therapy failure were consecutively enrolled at Seoul National University Bundang Hospital from 2003 to 2018. All patients took moxifloxacin-containing triple therapy as the second-line eradication therapy. The treatment regimen comprised a three-drug combination comprising a proton pump inhibitor, amoxicillin, and moxifloxacin. Data on age, sex, endoscopic diagnosis, eradication results, compliance, and adverse outcomes were acquired and analyzed.Results: In total, 824 participants were enrolled during the study period, of whom, 46 were lost to follow-up. Finally, 778 participants were included in the per-protocol (PP) analysis, of whom, 72.1% received moxifloxacin-containing triple therapy for 14 days. The eradication rate of moxifloxacin-containing triple therapy was 72.1% (594/824) in the intention-to-treat analysis and 76.3% (594/778) in the PP analysis. A decline in eradication efficacy was observed, especially in the PP analysis (<i>P</i>=0.046). Diarrhea was the most commonly observed adverse event, accounting for 19.6% (41/209) of recorded adverse events.Conclusions: Moxifloxacin-containing triple therapy has shown suboptimal eradication efficacy as the second-line eradication therapy. In addition, there is a concern that eradication rate will decrease due to increase in antimicrobial resistance.

Objectives. The aim of this study was to investigate and compare the eradication rate of Helicobacter pylori as the third-line triple therapy with rabeprazole (RPZ) + amoxicillin (AMPC) + levofloxacin (LVFX) and high-dose RPZ + AMPC. Methods. 51 patients who failed Japanese first-line (proton pump inhibitor (PPI) + AMPC + clarithromycin) and second-line (PPI + AMPC + metronidazole) eradication therapy were randomly assigned at a 1 : 1 ratio to one of the following third-line eradication groups: (1) RAL group: RPZ 10 mg (b.i.d.), AMPC 750 mg (b.i.d.), and LVFX 500 mg (o.d.) for 10 days; (2) RA group: RPZ 10 mg (q.i.d.) and AMPC 500 mg (q.i.d.) for 14 days. Patients who failed to respond to third-line eradication therapy received salvage therapy. Results. The rates of eradication success, based on intention to treat (ITT) analysis, were 45.8% in the RAL group and 40.7% in the RA group. The overall eradication rates were 73.9% in the RAL group and 64.0% in the RA group. There was no significant difference between the two groups. Conclusions. The third-line triple therapy with RPZ, AMPC, and LVFX was as effective as that with high-dose RPZ and AMPC.

<b><i>Backgrounds/Aims:</i></b> Vonoprazan (VPZ) is the first clinically available potassium competitive acid blocker. This class of agents provides faster and more potent acid inhibition than proton pump inhibitors. Most strains of <i>Helicobacter pylori</i> are sensitive to amoxicillin. We hypothesized that dual therapy with VPZ and amoxicillin would provide the sufficient eradication rate for <i>H. pylori</i> infection. To evaluate this, we compared the eradication rate by the dual VPZ/amoxicillin therapy with that by the standard triple VPZ/amoxicillin/clarithromycin therapy. <b><i>Methods:</i></b> Non-inferiority of the eradication rate of <i>H. pylori</i> by the dual therapy with VPZ 20 mg twice daily (bid) and amoxicillin 500 mg 3 times daily (tid) for 1 week to that by the triple therapy with VPZ 20 mg bid, amoxicillin 750 mg bid and clarithromycin 200 mg bid for 1 week was retrospectively studied. Propensity score matching was performed to improve comparability between 2 regimen groups. Successful eradication was diagnosed using the [<sup>13</sup>C]-urea breath test at 1–2 months after the end of eradication therapy. <b><i>Results:</i></b> The intention-to-treat analysis demonstrated that the eradication rate by the dual therapy (92.9%; 95% CI 82.7–98.0%, 52/56) was not inferior to that of the triple therapy (91.9%; 95% CI 80.4–97.0%, 51/56; OR 1.275, 95% CI 0.324–5.017%, <i>p</i> = 0.728). There were no statistically significant differences in incidences of adverse events between 2 regimens. <b><i>Conclusion:</i></b> VPZ-based dual therapy (VPZ 20 mg bid and amoxicillin 500 mg tid for 1 week) provides an acceptable eradication rate of <i>H. pylori</i> infection without the need for second antimicrobial agents, such as clarithromycin.

The eradication of Helicobacter pylori (H. pylori) may be difficult due to antibiotic resistance. Indeed, after one failure, a second-line therapy is needed and a bismuth containing quadruple therapy (BQT) with a three-in-one capsule formulation is becoming very popular. Therefore, we aimed to evaluate effectiveness and safety of BQT as a second-line therapy. We recruited consecutive patients with one therapy failure. For ten days patients received the three-in-one BQT Pylera® therapy, in combination with a proton-pump inhibitor (PPI), decided at the choice of the investigator, at full dose bid. The eradication rate was calculated by intention-to-treat (ITT) and per-protocol (PP)analyses and 95% confidence intervals (CI) were calculated. Seventy-three patients were recruited, 41 females and 32 males (mean age 53.0±13.1 years). Fifty-five patients failed triple therapy with amoxicillin and clarithromycin and the remaining 18 received sequential therapy. Seventy-two patients consumed at least 90% of the capsules, while only one did not complete the therapy due to adverse events (nausea and diarrhea). By ITT analysis, BQT was successful in 62 subjects (eradication rate 84.9%, 95%CI 76.7–93.1%). By PP analysis, the eradication rate was 86.1% (95%CI 78.1–94.1%).Adverse events were observed in 14 subjects (20.5%).In conclusion, our report confirmed that BQT is effective as an empiric second-line regimen.

This randomized controlled study aimed to evaluate whether adding bismuth to the standard first-line triple therapy could improve the eradication rate of Helicobacter pylori. A total of 162 patients with Helicobacter pylori infection were randomly assigned to either the 7-day triple therapy group (RAK regimen: rabeprazole 20 mg, amoxicillin 1 g, and clarithromycin 500 mg bid; n=81) or the bismuth plus triple therapy group (n=81). In the RBAK group, bismuth subcitrate 360 mg twice daily was added to the RAK regimen. A follow-up endoscopy or urea breath test was performed at least 4 weeks after eradication to confirm the treatment efficacy. Comparable compliance and Helicobacter pylori eradication rates were observed in both groups in either intention-to-treat [RAK 72.8% (59/81) versus RBAK 77.8% (63/81); p=0.47] or per protocol analysis [RAK 74.7% (59/79) versus RBAK 81.8% (63/77); p=0.26]. Adverse effects were commonly reported (50.6% for both groups) although most of these did not cause cessation of treatment. The resistance rate was 27.2% for metronidazole and 12.3% for clarithromycin. Adding bismuth to the standard 7-day triple therapy did not substantially increase the eradication rate. Further study is needed clarifying whether extending the duration of RBAK regimen to 10–14 days can lead to a better result.

ABSTRACTSitafloxacin-based triple therapy achieved 83.6% (per-protocol) and 78.2% (intention-to-treat) success in eradicatingHelicobacter pyloriamong 78 Japanese patients after clarithromycin-based first-line and metronidazole-based second-line triple therapies failed. Eradication succeeded in 32 out of 43 patients, even withgyrAmutation-positiveHelicobacter pylori(per protocol). The position of thegyrAmutation (N87 or D91) was determined to be a better marker than MIC levels for predicting outcomes of sitafloxacin-based treatment.

BackgroundCurrent guidelines recommend bismuth-containing quadruple therapy (BQT) and quinolone-containing therapy after failure of first-line Helicobacter pylori eradication therapy. However, the optimum regimen of second-line eradication therapy remains elusive. We conducted a network meta-analysis to compare the relative efficacy of 16 second-line H. pylori eradication regimens.MethodsThree major bibliographic databases were reviewed to enrol relevant randomised controlled trials between January 2000 and September 2018. Network meta-analysis was conducted by STATA software and we performed subgroup analysis in countries with high clarithromycin resistance and high levofloxacin resistance, and in patients with documented failure of first-line triple therapy.ResultsFifty-four studies totalling 8752 participants who received 16 regimens were eligible for analysis. Compared with a 7-day BQT, use of probiotic add-on therapy during, before, and after second-line antibiotic regimens, quinolone-based sequential therapy for 10–14 days, quinolone-based bismuth quadruple therapy for 10–14 days, bismuth quadruple therapy for 10–14 days, and quinolone-based triple therapy for 10–14 days were significantly superior to the other regimens. Subgroup analysis of countries with high clarithromycin resistance and high levofloxacin resistance revealed that the ranking of second-line eradication regimens was distributed similarly in each group, as well as in patients with failure of first-line triple therapy.ConclusionWe conducted a detailed comparison of second-line H. pylori regimens according to different antibiotic resistance rates and the results suggest alternative treatment choices with potential benefits beyond those that could be achieved using salvage therapies recommended by guidelines.

Abstract Background Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in the world affecting over 50% of the world’s population. H. pylori is a grade I carcinogen, responsible for the development of 89 % of noncardia gastric cancers. In the present study we analyzed the data for H. pylori eradication treatments in Slovenia. Patients and methods Slovenia is a part of the European Registry on Helicobacter pylori Management from the beginning. In seven medical institutions data for H. pylori eradication treatments was collected for 1774 patients from April 16th 2013 to May 15th 2016. For further modified intention to treat (mITT) analysis 1519 patients were eligible and for per protocol (PP) analysis 1346 patients. Results Patients’ dropout was 11.4%. Eradication rate for 7 day triple therapy with proton pump inhibitor (PPI) + Clarithromycin (C) + Amoxicillin (A) was 88.7% PP and 72.0% mITT; for PPI + C + Metronidazole (M) 85.2% PP and 84.4% mITT. Second line 14 day therapy PPI + A + Levofloxacin had 92.3% eradication rate PP and 87.1% mITT. Ten to fourteen day Bismuth quadruple therapy was the therapy in difficult to treat patients. At the end all patients that adhered to prescribed regimens were cured of their H. pylori infection. Conclusions High dropout rate deserves further analysis. Slovenia is still a country with < 15% H. pylori resistance to clarithromycin, triple therapy with PPI plus two antibiotics reaches PP eradication rate > 85%, but mITT eradication rates are suboptimal.

Background and Objectives: The prevalence of H. pylori in Eastern Europe remains quite high; however, there is insufficient data on the eradication regimens and their effectiveness. Therefore, the objective of the study was to evaluate the diagnostic methods and treatment of H. pylori infection as well as their adherence to Maastricht V/Florence consensus during the years 2013–2020 in Lithuania. Materials and Methods: Sub-study of the “European Registry on H. pylori Management” (Hp-EuReg), international multicenter prospective non-interventional registry of the routine clinical practice. Lithuanian data from the years 2013–2020 were analyzed for effectiveness on a modified intention-to-treat (mITT) basis. 2000 adult patients, diagnosed with H. pylori infection, were included. Data were compared to the European Maastricht V guidelines. Results: Triple-therapy was used in 90% of the cases. In 91% of the first-line prescriptions, standard triple therapy (STT) was used. The most common second-line treatment was a combination of PPI, amoxicillin and levofloxacin (PPI+A+L) (47%). The overall effectiveness in 552 cases valid for analysis was 90% by mITT. In first-line treatment, the STT effectiveness was 90% and second-line treatment with PPI+A+L achieved 92% by mITT. Increasing overall H. pylori eradication rates were observed: from 72% in 2013 to more than 90% in 2018–2020, as well as a shift from 7 to 10–14 days treatments duration throughout 2013–2020. Conclusions: In Lithuania, the prescribed eradication regimens for H. pylori were in accordance with the international guidelines but diagnostic methods and treatment duration only partially met Maastricht V/Florence guidelines. The eradication effectiveness was improved progressively during the years 2018–2020, reaching ≥90% cure rates.
