Independent Risk Factors Predicting Eradication Failure of Hybrid Therapy for the First-Line Treatment of Helicobacter pylori Infection. Microorganisms 2023; 12:6. [PMID: 38276175 PMCID: PMC10820614 DOI: 10.3390/microorganisms12010006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Revised: 12/10/2023] [Accepted: 12/12/2023] [Indexed: 01/27/2024] Open
Abstract
Hybrid therapy is a recommended first-line anti-H. pylori treatment option in the American College of Gastroenterology guidelines, the Bangkok Consensus Report on H. pylori management, and the Taiwan H. pylori Consensus Report. However, the cure rates of eradication therapy in some countries are suboptimal, and the factors affecting the treatment efficacy of hybrid therapy remain unclear. The aim of this study is to identify the independent risk factors predicting eradication failure of hybrid therapy in the first-line treatment of H. pylori infection. A retrospective cohort study was conducted on 589 H. pylori-infected patients who received 14-day hybrid therapy between September 2008 and December 2021 in ten hospitals in Taiwan. The patients received a hybrid therapy containing a dual regimen with a proton pump inhibitor (PPI) plus amoxicillin for an initial 7 days and a quadruple regimen with a PPI plus amoxicillin, metronidazole and clarithromycin for a final 7 days. Post-treatment H. pylori status was assessed at least 4 weeks after completion of treatment. The relationships between eradication rate and 13 host and bacterial factors were investigated via univariate and multivariate analyses. In total, 589 patients infected with H. pylori infection were included in the study. The eradication rates of hybrid therapy were determined as 93.0% (95% confidence interval (CI): 90.9-95.1%), 94.4% (95% CI: 93.8-97.2%) and 95.5%% (95% CI: 93.8-97.2%) by intention-to-treat, modified intention-to-treat and per-protocol analyses, respectively. Univariate analysis showed that the eradication rate of clarithromycin-resistant strains was lower than that of clarithromcyin-susceptible strains (83.3% (45/54) vs. 97.6%% (280/287); p < 0.001). Subjects with poor drug adherence had a lower cure rate than those with good adherence (73.3% (11/15) vs. 95.5% (534/559); p = 0.005). Other factors such as smoking, alcohol drinking, coffee consumption, tea consumption and type of PPI were not significantly associated with cure rate. Multivariate analysis revealed that clarithromcyin resistance of H. pylori and poor drug adherence were independent risk factors related to eradication failure of hybrid therapy with odds ratios of 4.8 (95% CI: 1.5 to 16.1; p = 0.009) and 8.2 (95% CI: 1.5 to 43.5; p = 0.013), respectively. A 14-day hybrid therapy has a high eradication rate for H. pylori infection in Taiwan, while clarithromycin resistance of H. pylori and poor drug adherence are independent risk factors predicting eradication failure of hybrid therapy.

Abstract
INTRODUCTION The study aimed to compare the efficacies and safety of 14-day hybrid therapy, 14-day high-dose dual therapy, and 10-day bismuth quadruple therapy in the first-line treatment of Helicobacter pylori infections. METHODS In this multicenter, open-label, randomized trial, we recruited adult H. pylori -infected patients from 9 centers in Taiwan. Subjects were randomly assigned (1:1:1) to 14-day hybrid therapy, 14-day high-dose dual therapy, or 10-day bismuth quadruple therapy. Eradication status was determined by the 13 C-urea breath test. The primary outcome was the eradication rate of H. pylori assessed in the intention-to-treat population. RESULTS Between August 1, 2018, and December 2021, 918 patients were randomly assigned in this study. The intention-to-treat eradication rates were 91.5% (280/306; 95% confidence interval [CI] 88.4%-94.6%) for 14-day hybrid therapy, 83.3% (255/306; 95% CI 87.8%-95.0%) for 14-day high-dose dual therapy, and 90.2% (276/306; 95% CI 87.8%-95.0%) for 10-day bismuth quadruple therapy. Both hybrid therapy (difference 8.2%; 95% CI 4.5%-11.9%; P = 0.002) and bismuth quadruple therapy (difference 6.9%; 95% CI 1.6%-12.2%; P = 0.012) were superior to high-dose dual therapy and were similar to one another. The frequency of adverse events was 27% (81/303) with 14-day hybrid therapy, 13% (40/305) with 14-day high-dose dual therapy, and 32% (96/303) with 10-day bismuth quadruple therapy. Patients receiving high-dose dual therapy had the fewest adverse events (both P < 0.001). DISCUSSION Fourteen-day hybrid therapy and 10-day bismuth quadruple therapy are more effective than 14-day high-dose dual therapy in the first-line treatment of H. pylori infection in Taiwan. However, high-dose dual therapy has fewer adverse effects than hybrid bismuth quadruple therapies.

Abstract
Background Knowledge of global clarithromycin (CLA)-resistant rates of Helicobacter pylori (H. pylori) is crucial for decision of the most appropriate eradication therapies with good clinical outcomes. Therefore, this review and meta-analysis aimed to evaluate the global prevalence of the CLA resistance in H. pylori to provide some guidance for selecting the first-line antibiotics. Method A comprehensive search was performed for relevant literature until April 2021 in PubMed, Embase, and Web of Science databases. Freeman-Tukey double arcsine transformation was performed to estimate the weighted pooled prevalence of resistance. Results The meta-analysis included 248 articles. The prevalence of CLA-resistant H. pylori was 27.53% (95% CI [25.41-29.69]). The heterogeneity between reports was significant (I2 = 97.80%, P < 0.01). The resistance rate increased from 24.28% in 2010-2017 to 32.14% in 2018-2021 (P < 0.01). Iran, with 38 articles, has the most report. Nevertheless, Switzerland, Portugal, and Israel had the highest resistance rates (67.16%, 48.11%, and 46.12%, respectively). The heterogeneity between the continents and the antimicrobial susceptibility methods also interpreted standard guidelines and breakpoints was insignificant (P > 0.05). Conclusion Overall CLA resistance rate was 27.53%, worldwide. The difference in CLA resistance rate among the included studies can be due to several reasons such as differences in antibiotic prescription rates in various geographic areas, use of different breakpoints or inaccurate criteria in performed studies, and the emergence of multidrug-resistant (MDR) strains.

Therap Adv Gastroenterol 2022; 15:17562848221138168. [PMID: 36458050 PMCID: PMC9706057 DOI: 10.1177/17562848221138168] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 10/24/2022] [Indexed: 11/23/2022] Open
Abstract
Current international consensuses on Helicobacter pylori eradication therapy recommend that only regimens that reliably produce eradication rates of ⩾90% should be used for empirical treatment. The Real-world Practice & Expectation of Asia-Pacific Physicians and Patients in Helicobacter Pylori Eradication Survey also showed that the accepted minimal eradication rate in H. pylori-infected patients was 91%. According to efficacy prediction model, the per-protocol eradication rates of 7-day and 14-day standard triple therapies fall below 90% when clarithromycin resistance rate ⩾5%. Several strategies including bismuth-containing, non-bismuth-containing quadruple therapies (including sequential, concomitant, hybrid and reverse hybrid therapies), high-dose dual therapy and vonoprazan-based triple therapy have been proposed to increase the eradication rate of H. pylori infection. According to efficacy prediction model, the eradication rate of 14-day concomitant therapy, 14-day hybrid therapy and 7-day vonoprazan-based triple therapy is less than 90% if the frequency of clarithromycin-resistant strains is higher than 90%, 58% and 23%, respectively. To meet the recommendation of the consensus report and patients' expectation, local surveillance networks for resistance of H. pylori to clarithromycin are required to select appropriate eradication regimens in each geographic region. In areas with low (<5%) clarithromycin resistance (e.g. Sweden, Philippine, Myanmar and Bhutan), 7-day and 14-day standard triple therapies can be adopted for the first-line treatment of H. pylori infection with eradication rates of ⩾90%. In areas with high (⩾5%) clarithromycin resistance (most other countries worldwide) or unknown clarithromycin resistance, 14-day hybrid, 14-day reverse hybrid, 14-day concomitant and 10- to 14-day bismuth quadruple therapy can be used to treat H. pylori infection.

Abstract
BACKGROUND The prevalence of Helicobacter pylori (H. pylori) in developing countries is 50.8%, with the highest occurrence presented in Africa (79.1%). It increases the risk of chronic gastritis, peptic ulcer, cancer of the stomach, and lymphoma. The effect of standard treatment for H. pylori eradication is below 80%, and evaluation of alternative lines of treatment is needed. We aimed to compare the hybrid, reverse hybrid, and levofloxacin quadruple therapies as first-line therapy in Egypt. METHODS This was a randomized interventional trial done in the clinics affiliated with the Internal Medicine Department. 330 individuals were selected according to the inclusion criteria. They were divided into three groups: group 1 (110 subjects who received a reverse hybrid regimen), group 2 (110 subjects who received a hybrid regimen), and group 3 (110 subjects who received a non-bismuth levofloxacin quadruple regimen). RESULTS Group 3 had a significantly lower eradication rate of 82.7% versus 92.7% and 91.8% in groups 1 and 2, respectively. There were non-significant differences in the incidence rates of adverse events among the three groups. CONCLUSION Both the reverse hybrid and hybrid groups had good eradication rates in the Egyptian population, but non-bismuth levofloxacin quadruple therapy did not obtain a sufficient eradication rate.

Abstract
Helicobacter pylori (HP) is a major causative agent of chronic gastritis and peptic ulcer. HP is also engaged in the development of gastric cancer and gastric mucosa-associated lymphoid tissue lymphoma. It is an important pathogenic factor in various other systemic diseases, such as vitamin B12 deficiency, iron deficiency, and idiopathic thrombocytopenia. The current consensus is that unless there is a special reason, eradication therapy should be implemented whenever HP infection is found, and it is ideally successful the first time. International guidelines recommend that under certain conditions, treatment should be personalized based on drug susceptibility testing. However, drug susceptibility testing is often not available because it is expensive, time-consuming, and difficult to obtain living tissue. Each region has separately formulated guidelines or consensuses on empirical therapy. Owing to an increasing drug resistance rate in various places, the eradication rate of proton pump inhibitor (PPI) triple therapy and sequential therapy has been affected. These regimens are rarely used; the PPI triple especially has been abandoned in most areas. Currently, radical treatment regimens for HP involve bismuth-containing quadruple therapy and concomitant therapy. However, quadruple therapy has its own limitations, such as complex drug administration. To improve the effectiveness, safety, and compliance, many clinical studies have proposed useful modified regimens, which mainly include the modified bismuth-containing quadruple regimen, high-dose dual therapy, and vonoprazan-containing regimens. Studies have shown that these emerging regimens have acceptable eradication rates and safety, and are expected to become first-line treatments in empirical therapy. However, the problem of decline in the eradication rate caused by drug resistance has not been fundamentally solved. This review not only summarizes the effectiveness of mainstream regimens in the first-line treatment of HP infection with the currently increasing antibiotic resistance rates, but also summarizes the effectiveness and safety of various emerging treatment regimens.

Abstract
BACKGROUND The efficacy and safety of reverse hybrid therapy in the treatment of Helicobacter pylori (H. pylori) infection remained unclear. MATERIALS AND METHODS This systematic review was performed in accordance with the PRISMA 2009 guidelines. A systematic search of the Pubmed, Embase, and Cochrane database was conducted using the combination of "Helicobacter pylori or H. pylori or Hp" and "hybrid". The primary endpoint of this meta-analysis was to evaluate the efficacy of reverse hybrid therapy; the second endpoint was to evaluate the efficacy of reverse hybrid therapy among the strains with antibiotic resistance and the compliance, safety of reverse hybrid therapy. RESULTS Four studies with 1530 participants were included. The crude H. pylori eradication rate of reverse hybrid therapy was 95.5% (737/772) and 96.2% (701/729) by ITT and PP analysis, respectively. There is no statistical significance of efficacy between reverse hybrid therapy and control according to ITT (pooled rate: 96% vs. 94%, RR = 1.02, 95% CI, 0.95-1.05, p = .28) and PP (pooled rate: 96% vs. 94%, RR = 1.02, 95% CI, 0.99-1.06, p = .23) analysis. The effect of reverse hybrid therapy in strains with isolated clarithromycin resistance (pooled rate: 89% vs. 65%, RR = 1.13, 95% CI, 0.77-1.66, p = .53), metronidazole resistance (pooled rate: 91% vs. 81%, RR = 1.00, 95% CI, 0.96-1.05, p = .85), and dual clarithromycin-metronidazole resistance (pooled rate: 86% vs. 83%, RR = 0.94, 95% CI, 0.69-1.27, p = .69) showed no superior to that of control. The compliance of reverse hybrid therapy is 96%, and side effect is slightly lower to that of control group. CONCLUSION Reverse hybrid therapy shows good efficacy, safety, and compliance in the treatment of H. pylori infection. However, its application for H. pylori treatment in regions with high antibiotic resistance need to be further explored.

Abstract
Introduction: Eradication of Helicobacter pylori (H. pylori) becomes more challenging due to increasing antimicrobial resistance. Consequently, the performance of clarithromycin-containing triple therapies is now declining to unacceptable levels and should be abandoned unless a prior susceptibility test precludes clarithromycin resistance.Areas covered: This review summarizes updated evidence concerning new and advancing pharmacotherapy options for H. pylori eradication.Expert opinion: Due to the declining efficacy of legacy triple therapies, most guidelines recommend bismuth quadruple therapy as the best initial empiric treatment. Concomitant, sequential and hybrid therapies are remarkable bismuth-free quadruple options, provided that dual clarithromycin-metronidazole resistance is low. Levofloxacin-, rifabutin-, furazolidone- and sitafloxacin-containing regimens remain useful, particularly as salvage options. To eradicate H. pylori in line with the rules of antibiotic stewardship, susceptibility-guided treatment appears as the ideal approach. However, the feasibility and cost-effectiveness of universal pre-treatment susceptibility testing warrants further evaluation. Molecular testing methods promise convenient characterization of H. pylori antibiotic susceptibility. High-dose dual therapy (proton-pump-inhibitor plus amoxicillin) and vonoprazan, a more potent acid inhibitor that likely enhances the activity of amoxicillin, are promising alternatives that could decrease misuse of antibiotics. Addition of certain probiotics could somewhat increase the performance of H. pylori eradication regimens, while improving tolerability.

Equivalent efficacies of reverse hybrid and concomitant therapies in first-line treatment of Helicobacter pylori infection. J Gastroenterol Hepatol 2020; 35:1731-1737. [PMID: 32167605 DOI: 10.1111/jgh.15034] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 03/09/2020] [Accepted: 03/10/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIM Concomitant therapy is a recommended first-line treatment for Helicobacter pylori infection in most national or international consensuses. Reverse hybrid therapy is a modified 14-day concomitant therapy without clarithromycin and metronidazole in the final 7 days. This study aims to test whether 14-day reverse hybrid therapy is non-inferior to 14-day concomitant therapy in the first-line treatment of H. pylori infection. METHODS Helicobacter pylori-infected adult patients were randomly assigned to receive either reverse hybrid therapy (dexlansoprazole 60 mg o.d. plus amoxicillin 1 g b.d. for 14 days, and clarithromycin 500 mg plus metronidazole 500 mg b.d. for initial 7 days) or concomitant therapy (dexlansoprazole 60 mg once o.d. plus amoxicillin 1 g, clarithromycin 500 mg, and metronidazole 500 mg b.d. for 14 days). H. pylori status was assessed 6 weeks after the end of treatment. RESULTS Helicobacter pylori-infected participants (n = 248) were randomized to receive either 14-day reverse hybrid therapy (n = 124) or 14-day concomitant therapy (n = 124). Intention-to-treat analysis demonstrated that the two therapies had comparable eradication rate (95.2% vs 93.5%; 95% confidence interval, -4.0% to 7.4%; P = 0.582). However, reverse hybrid therapy had a much lower frequency of adverse events than concomitant therapy (20.2% vs 38.7%, P = 0.001). The two therapies exhibited comparable drug adherence (93.5% vs 87.9%, P = 0.125). CONCLUSIONS Fourteen-day reverse hybrid therapy and 14-day concomitant therapy are equivalent in efficacy for the first-line treatment of H. pylori infection. However, reverse hybrid therapy has fewer adverse events compared with concomitant therapy.
