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.

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.

The most commonly used regimen forHelicobacter pyloritherapy at present is twice-daily proton pump inhibitor (PPI)-based triple therapy. Bismuth-based therapy is the next most common treatment used by gastroenterologists. When a PPI is combined with bismuth-based triple therapy (quadruple therapy), eradication rates are increased as compared with the triple therapy alone. Three separate randomized trials from three continents that compare quadruple therapy and PPIbased triple therapy revealed remarkably similar results. Eradication rates with PPI-based triple therapy and quadruple therapy were not significantly different. The eradication rates with quadruple therapy were 3% to 6% higher than PPI triple therapy, indicating that quadruple therapy should be no less effective than PPI triple therapy. Furthermore, these two therapies had similar rates of compliance and adverse events.The major potential benefit of the quadruple therapy relates to antibiotic resistance. In patients with clarithromycin resistance, PPIbased triple therapy, but not quadruple therapy, had a significantly lower eradication rate. However, due to its ability to largely overcome metronidazole resistance, quadruple therapy had little if any decrement in eradication rates compared with PPI triple therapy in patients with metronidazole-resistantH pylori. Therefore, quadruple therapy can be considered a first line therapy forH pylori.

Bismuth quadruple therapy (BQT) is an effective treatment for Helicobacter pylori infection. However, frequent dosing schedules of BQT regimen often compromise drug adherence and may affect treatment outcomes. This retrospective study aimed to investigate the efficacy of twice-daily BQT compared to that of four times a day therapy. From August 2018 to November 2020, adult patients who failed first-line standard triple therapy and underwent BQT were eligible. Patients were categorized into two groups according to dosing schedule: (i) the BQT group (n = 213) who received standard BQT administered four times a day; and (ii) the BQTb group (n = 141) who received proton pump inhibitor, bismuth 600 mg, metronidazole 500 mg, and tetracycline 1 g twice a day. The eradication rate did not differ between the BQT (92.5%) and the BQTb groups (90.1%) (p = 0.441). Adherence and adverse event rate were similar between the two groups. Multivariate analysis showed that current smoking was associated with eradication failure; however, dosing frequency was not associated with the efficacy of eradication therapy. This study suggested that twice a day BQT is as effective as four times a day therapy for second-line treatment of H. pylori infection.

Abstract Background Increasing clarithromycin resistance has led to the need for an alternative first-line therapy for the eradication of Helicobacter pylori (H. pylori) in Korea, and bismuth containing quadruple therapy (BQT) and tailored therapy (TT) have been proposed as alternative regimens. The aim of this study was to compare the eradication rates of BQT and TT as first-line H. pylori eradication therapies. Methods H. pylori infection was diagnosed using the rapid urease test or dual-priming oligonucleotide-based multiplex polymerase chain reaction (DPO-PCR) during endoscopy. Patients positive for H. pylori were divided into two groups; those tested using the rapid urease test received empirical BQT (the BQT group) whereas those tested by DPO-PCR received TT (the TT group). Eradication rates, adverse events, and overall medical costs, which included diagnostic test and eradication regimen costs, were compared. Results Three hundred and sixty patients were included in the study (TT group 178, BQT group 182). The modified intention-to-treat eradication rates of BQT and TT were 88.2% (142/161) and 80.3% (118/147), respectively (p=0.055), and corresponding eradication rates in the per-protocol population were 88.8% (142/160) and 81.4% (118/145) (p=0.07). Compliance and adverse event rates were similar in the two groups. Average medical costs were $ 90.3 per patient in the TT group and $ 75.5 in the BQT group (p=0.000). Conclusions Empirical BQT and tailored therapy were similar in terms of H. pylori eradication rate, safety, and tolerability, but BQT was more cost-effective.

Background: Helicobacter pylori resistance to amoxicillin remains rare in many regions. Proton pump inhibitor-amoxicillin-containing high dose dual therapy (HDDT) has been proposed to treat H. pylori infection. We aimed to assess the effectiveness and safety of PPI-amoxicillin HDDT for treatment of H. pylori infection in comparison with other regimens. Methods: Databases, including PubMed, Embase, and the Cochrane Register of Controlled Trials, were searched to find relevant publications. Randomized controlled trials comparing HDDT with control regimens for H. pylori eradication in adult patients were included. The primary outcome was eradication rate by intention-to-treat analysis. Adverse events were analyzed as second outcome. Results: A total of 15 trials with 3818 patients qualified for inclusion. The eradication rate of HDDT was neither significantly inferior nor superior to the recommended regimens such as triple therapy, bismuth quadruple therapy, and non-bismuth quadruple therapy [relative risk (RR): 1.00, 95% confidence interval (CI): 0.96–1.05, p = 0.870]. This finding was robust through subgroup analyses and sensitivity analyses. Trial sequential analysis showed that HDDT was equivalent to control regimens, and further similar trials were unlikely to alter the conclusions of this analysis. The frequency of adverse events was significantly lower in HDDT group (RR: 0.48, 95% CI: 0.37–0.64, p < 0.001). Conclusion: HDDT was equivalent to recommended first-line or rescue regimens with fewer adverse effects. The evidence from this meta-analysis supports the use of HDDT as first-line or rescue treatment for H. pylori infection. Trial registration: PROSPERO CRD42019133002

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.
