Introduction.Helicobacter pylorieradication therapy has the potential burden of antibiotic-associated gastrointestinal (GI) side effects. The occurrence of side effects is among the major drawbacks of such regimens. GI manifestations may be related to alterations in the intestinal microflora. Probiotics can prevent or reduce antibiotic-associated side effects and have an inhibitory effect onH. pylori.Methods. To define the efficacy ofLactobacillus reuterisupplementation inH. pylorieradication and in preventing GI-associated side effects during a second-line levofloxacin triple therapy. 90H. pylori-positive patients receive for 7 days a second-line triple therapy with esomeprazole, levofloxacin, and amoxicillin withL. reuterifor 14 days (group 1) and without probiotic supplementation (group 2). Each subject received a validated questionnaire to record symptoms everyday for 4 weeks from the start of therapy.H. pyloristatus and side effects were assessed 6 weeks after treatment.Results. The eradication rate was significantly influenced by probiotic supplementation withL. reuteri(group 1: 36/45, 80%; group 2: 28/45 62%;P<0.05). The incidence of nausea and diarrhoea in group 1 was significantly lower than that in group 2.Conclusion. InH. pylori-positive subjectsL. reuterisupplementation increases the eradication rate while reducing the incidence of the most common side effects associated with antibiotic therapy in second-line treatment.

Aim. Evaluation of the efficacy and safety of quadrupletherapy without bismuth (concomitant therapy) in patients with Helicobacter pylori - associated gastric ulcer and duodenal ulcer in the framework of a comparative research in the population of patients in Russia. Materials and methods. A prospective randomized trial was conducted, which included 210 patients with H. pylori - associated gastric/duodenal ulcer without complications. During the process of randomization, the patients were divided into three equal groups (n=70) depending on the prescribed 10-day scheme of eradication therapy (ET): the first group received the classic triple scheme (Omeprazole 20 mg 2 times a day, Amoxicillin 1000 mg 2 times a day and Clarithromycin 500 mg 2 times a day); the second group received quadruple therapy with bismuth drugs (Omeprazole 20 mg 2 times a day, Tetracycline 500 mg 4 times a day, Metronidazole 500 mg 3 times a day, Bismuth subcitrate potassium 120 mg 4 times a day); the third group received quadruple therapy without bismuth - concomitant therapy (Omeprazole 20 mg 2 times a day, Amoxicillin 1000 mg 2 times a day, Clarithromycin 500 mg 2 times a day and Metronidazole 500 mg 2 times a day). Diagnostics of H. pylori infection during screening and control of eradication was carried out via the fast urease biopsy sample test and urea breath test system. Control of the effectiveness of ET of the microorganism was carried out not earlier than 4 weeks after the end of the treatment. During the course of therapy, the frequency of development of side effects was assessed using a special questionnaire. Results and discussion. The effectiveness of triple therapy was 72.8% (ITT; 95% CI of 62.17-83.54) and 78,4% (PP; 95% CI 68.19-88.72); quadruple therapy with the preparation of bismuth - 80.0% (ITT; 95% CI 70.39-89.6) and 84,8% (PP; 95% CI, 75.96-93.73); quadruple therapy without bismuth - concomitant therapy - 84.2% (ITT; 95% CI 75.54-93.02) and 92.1% (PP; 95% CI 85.43-98.94). Quadruple therapy without bismuth was reliably more effective than the classical triple therapy in the PP selection (p=0.044883). Statistical analysis showed a tendency to poorer effectiveness of ET in patients who had previously used antibiotic therapy (OR 0.4317; 95% CI 0.1776-1.049), and in individuals with a rapid metabolism genotype - CYP2C19*1/*1 (OR 0.12; 95% CI 0.005848-2.4624). The frequency of development of side effects during the use of triple therapy was 18.5% (95% CI of 9.23-27.91), when using quadruple therapy with bismuth - 20.0% (95% CI 10.39-29.6), and with the use of quadruple therapy without bismuth - concomitant therapy - 24.2% (95% CI 13.98-34.58). Conclusion. This prospective randomized study demonstrated the high efficiency of quadruple therapy without bismuth (concomitant therapy) in the framework of eradication of H. pylori infection in Russia.

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.

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.

<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.

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.

The article presents the results of a comparative study of the efficacy and tolerability of two 10-day eradication therapy regimens of Helicobacter pylori (HP) infection (triple and triple with the addition of bismuth tripotassium dicitrate (BTD). The study involved 158 patients with HP-associated pathology (dispepsia, erosive and ulcerative lesions of the gastroduodenal mucosa) from 18 to 65 years of age (mean age=44,6±13,5 years): 57 men (36,1 %), 101 women (63,9 %). The diagnostics of HP-infection performed using a rapid urease test (Helpil test St'Petersburg) in the course fibrogastroduodenoscopy (FGDS). The patients were divided randomly into two groups. In the group 1, 75 patients received classical first-line triple therapy: esomeprazole 20 mg twice a day, amoxicillin 1 000 mg twice a day, clarithromycin 500 mg twice a day. In the group 2, 83 patients received treatment using a similar regimen, but with the addition of BTD 240 mg twice a day. The duration of treatment in both groups was 10 days. The effectiveness of the eradication therapy was evaluated after 6-8 weeks of the end of the treatment course by means of qualitative rapid determination of fecal HP antigens using the method of immunochromatography with monoclonal antibodies (Vegal Farmaceutica, Spain). Out of the 75 patients in group 1, 60 (80 %) showed eradication of HP infection was achieved. Out of 83 patients in group 2, the eradication of HP infection was achieved in 76 patients (92,5 %). The difference in the effectiveness of eradication therapy in patients in group 1 and group 2 is statistically significant (p<0,05). Thus, the classical 10-day regimen of triple antihelicobacter therapy is not effective enough and is not recommended for use in clinical practice in Khabarovsk. A 10-day triple therapy with the addition of BTD is highly effective in the Far Eastern region (Khabarovsk) and recommended as a first-line therapy. A significant reduction in the adverse events frequency in the form of bitter taste in the mouth and diarrhea is an additional advantage of the regimen using bismuth tripotassium dicitrate in comparison with the classical regimen of the triple antihelicobacter therapy.

Background/Aims: It is still unknown whether cytochrome P450 (CYP) 2C19 polymorphisms influence <i>Helicobacter pylori</i> (<i>H. pylori</i>) eradication, especially in eastern Asia. We aimed to evaluate how changes in proton pump inhibitor (PPI) strategies could be used to overcome the effects of CYP2C19 polymorphism on <i>H. pylori</i> eradication rate when it is used as the second-line regimen after the failure of standard triple therapy.Materials and Methods: We performed a retrospective observation study of 675 patients in whom standard triple therapy for <i>H. pylori</i> infection was not effective between January 2009 to December 2018. All patients underwent a classic bismuth-containing quadruple therapy (10 to 14-day regimen), and their eradication rates were evaluated for several years. We compared the eradication rates in patients with or without the second-line PPI switch. Further, we assessed differences in eradication rates with or without the strategy using esomeprazole and rabeprazole, which are not influenced significantly by CYP2C19 genetic polymorphism.Results: The eradication rate was 81.0% in individuals who received the second-line PPI switch, but it was 74.8% without switching (<i>P</i>=0.14). In the strategy using esomeprazole and rabeprazole, the eradication rate was 84.6%, compared to 76.5% in the control group (<i>P</i>=0.03). Finally, in the group of patients who switched to rabeprazole, the eradication rates were 85.6%, compared to 77.6% in the group who switched to pantoprazole (<i>P</i>=0.05).Conclusions: Switching to PPI, which is not influenced by CYP2C19 genetic polymorphism, increases the efficiency of eradication after the failure of standard triple therapy.

Eradication of Helicobacter pylori (H. pylori) is an effective strategy for preventing various gastrointestinal diseases such as gastric cancer and mucosa-associated lymphoid tissue (MALT) lymphoma. However, the eradication success rate is decreasing because of a recent increase in drug-resistant strains of H. pylori. Here, we evaluated the success rate of eradication therapy with vonoprazan (VPZ), a new potassium-competitive acid blocker, against drug-resistant H. pylori. In total, 793 patients who received H. pylori eradication therapy were investigated retrospectively. All underwent esomeprazole (EPZ)-based triple therapy (n = 386) or VPZ-based triple therapy (n = 407) for first-, second- and third-line H. pylori eradication for 7 days. The overall success rates of first- and third-line H. pylori eradication were significantly higher for VPZ-based triple therapy (88.4% and 93.0%, respectively, per protocol (PP)) than for EPZ-based triple therapy (69.5% and 56.5%, respectively, PP). Moreover, the success rates of first- and third-line eradication of clarithromycin (CLR)- and sitafloxacin (STFX)-resistant H. pylori were significantly higher for VPZ-based triple therapy (72.0% and 91.7%, PP) than for EPZ-based triple therapy (38.5% and 20.0%, PP). In addition, patient age did not affect the eradication rate of VPZ-based first-line therapy, whereas the success rate of EPZ-based therapy was lower in patients under 65 years of age. Our results clearly demonstrated that VPZ-based therapy achieved a higher eradication rate even against CLR- and STFX-resistant H. pylori, and that patient age did not affect the eradication rate of VPZ-based therapy. These findings suggest that dual therapy using VPZ and amoxicillin may be sufficient for standard H. pylori eradication, and may thus also be beneficial for avoiding antibiotic misuse.

Triple therapy is accepted as the treatment of choice for H. pylori eradication. In industrialized countries, a proton pump inhibitor plus clarithromycin and amoxicillin or nitroimidazole have shown the best results. Our aims were: 1. To study the eradication rate of the association of a proton pump inhibitor plus tinidazole and clarithromycin on H. pylori infection in our population. 2. To determine if previous treatments, gender, age, tobacco, alcohol use, and non-steroidal anti-inflammatory drugs (NSAIDs) change the response to therapy. METHODS: Two hundred patients with peptic ulcer (upper endoscopy) and H. pylori infection (histology and rapid urease test - RUT) were included. A proton pump inhibitor (lansoprazole 30 mg or omeprazole 20 mg), tinidazole 500 mg, and clarithromycin 250 mg were dispensed twice a day for a seven-day period. Eradication was assessed after 10 to 12 weeks of treatment through histology and RUT. RESULTS: The eradication rate of H. pylori per protocol was 65% (128/196 patients). This rate was 53% for previously treated patients, rising to 76% for not previously treated patients, with a statistical difference p<0.01. No significant difference was observed regarding sex, tobacco use, alcohol consumption, and NSAID use, but for elderly patients the difference was p = 0.05. Adherence to treatment was good, and side effects were mild. CONCLUSIONS: A proton pump inhibitor, tinidazole, and clarithromycin bid for seven days resulted in H. pylori eradication in 65% of the patients. Previous treatments were the main cause of treatment failure.
