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.

The Efficacy and Safety of 14-day Rabeprazole Plus Amoxicillin High Dose Dual Therapy by Comparing to 14-day Rabeprazole-Containing Hybrid Therapy for the Naïve Helicobacter pylori Infection in Taiwan: A Randomized Controlled Trial. Infect Dis Ther 2023; 12:1415-1427. [PMID: 37133673 PMCID: PMC10229508 DOI: 10.1007/s40121-023-00811-3] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2023] [Accepted: 04/14/2023] [Indexed: 05/04/2023] Open
Abstract
INTRODUCTION High-dose dual therapy (HDDT) can attain acceptable eradication rates provided that the optimal doses, timing and treatment duration are applied. The existing evidence still shows inconsistent reports (< 90%) on HDDT therapy except in some Asian countries. We aimed to assess and compare the efficacy of 14-day HDDT by comparing it to 14-day rabeprazole-containing hybrid therapy (HT) and to investigate the host and bacterial factors predicting the treatment outcomes of eradication therapies. METHODS In this open-label, randomized controlled trial, we recruited 243 naïve Helicobacter pylori-infected patients from September 1, 2018, to November 30, 2021. They were randomly allocated (1:1) to the HDDT group (rabeprazole 20 mg and amoxicillin 750 mg q.i.d for 14 days, n = 122) and the HT group (rabeprazole 20 mg and amoxicillin 1 g b.i.d. for 7 days, followed by rabeprazole 20 mg, amoxicillin 1 g, clarithromycin 500 mg and metronidazole 500 mg b.i.d. for 7 days, n = 121). Twelve patients were absent during follow-up in the HDDT group and 4 in the HT group, resulting in 110 for the HDDT group and 117 for HT group in the per protocol (PP) study. The outcome was determined by urea breath tests 8 weeks later. RESULTS The eradication rates for the HDDT and HT groups were 77.0% (95% confidence interval [CI]: 68.5% to 84.1%) and 94.2% (95% CI: 88.4% to 97.6%) (P < 0.001) in intention-to-treat analysis; 85.5% (95% CI: 77.5% to 91.5%) and 97.4% [95% CI: 92.6% to 99.5%] (P = 0.001) in per protocol analysis. The adverse event rates were 7.3% in the HDDT group and 14.5% in the HT group (P = 0.081). The habit of coffee drinking was the dependent factor for eradication failure in the HDDT group (88.2% vs. 68.8%, P = 0.040), but had no influence in the HT group (97.9% versus 95.0%, P = 0.449) in the univariate analysis. CONCLUSION This study demonstrated that 14-day rabeprazole-containing HDDT did not achieve > 90% eradication rates for first-line H. pylori eradication as 14-day rabeprazole-containing HT did. HDDT is a potentially beneficial combination, which involves only two drugs with mild adverse effects; more precise studies are urged to find answers regarding these failures. This clinical trial was registered retrospectively on 28 November, 2021, as ClinicalTrials.gov identifier: NCT05152004.

Front Pharmacol 2023; 14:1096103. [PMID: 36817141 PMCID: PMC9931190 DOI: 10.3389/fphar.2023.1096103] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2022] [Accepted: 01/23/2023] [Indexed: 02/04/2023] Open
Abstract
Background: Currently, the management of Helicobacter pylori (H. pylori) infection in elderly patients is controversial. We investigated whether high-dose dual therapy would serve as the first-line therapy in elderly patients. Methods: This was a single-center, randomized study of 150 elderly patients with H. pylori infection who were randomly assigned to 14-day therapy with pantoprazole 40 mg 3 times daily and either amoxicillin 1,000 mg 3 times daily or amoxicillin 1,000 mg twice daily, clarithromycin 500 mg twice daily and bismuth 220 mg twice daily. H. pylori eradication was evaluated by a 13C-urea breath test 4 weeks after the completion of treatment. Results: Successful eradication was achieved in 89.3% of the high-dose dual therapy (HT) group in the intention-to-treat (ITT) analysis, 91.7% in the modified intention-to-treat (mITT) analysis, and 93.0% for per-protocol (PP) analysis which was similar to the bismuth-containing quadruple therapy (BQT) group (86.6%, 87.8%, and 90.3%, respectively). There were no significant difference between the HT group and the BQT group in the ITT analysis (p = 0.484), mITT analysis (p = 0.458), or PP analysis (p = 0.403). HT was associated with fewer side effects (10.6% of patients) than BQT (26.6%) (p = 0.026). Conclusion: In this trial, we found that 14-day HT had a similar eradication rate to BQT but fewer side effects, which may be better for elderly patients.

Abstract
Half of the world's population is Helicobacter pylori carrier. Updated guidelines and consensus have been issued across regions with the main aim of reducing social transmission and increasing H. pylori eradication rate. Although alternative therapies including traditional Chinese medicine and probiotics have also been used to improve H. pylori eradication rate in clinical practice, current mainstream treatment is still dependent on triple and quadruple therapies that includes antibacterial agents (e.g., amoxicillin and furazolidone) and proton pump inhibitor. Researches also assessed the eradication rate of optimized high-dose dual therapy in treating H. pylori infection. With the increase of antibiotic resistance rate, the treatment strategies for H. pylori infection are constantly adjusted and improved. Besides, low medication compliance is another key influencing factor for H. pylori treatment failure. Emerging studies indicate that pharmacists' intervention and new pharmaceutical care methods can enhance patient medication compliance, reduce adverse drug reactions, and improve H. pylori eradication rate. The purpose of this review is to summarize the advances in treating H. pylori infection and highlight the necessity of developing novel strategies to cope with the increasing challenges and to achieve personalized medication. Also, this review attaches great importance to pharmacists in optimizing H. pylori treatment outcomes as a routine part of therapy.

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
Helicobacter pylori infection usually causes gastrointestinal complications, including gastrointestinal bleeding or perforation, and serious infections may lead to gastric cancer. Amoxicillin is used to treat numerous bacterial infections but is easily decomposed in the gastric acid environment via the hydrolyzation of the β-lactam ring. In this study, we develop chitosan-based nanoparticles loaded with amoxicillin (CAANs) as an H. pylori eradication platform. The CAANs were biocompatible and could retain the antibiotic activity of amoxicillin against H. pylori growth. The mucoadhesive property of chitosan and alginate enabled the CAANs to adhere to the mucus layers and penetrate through these to release amoxicillin in the space between the layers and the gastric epithelium. The use of this nanoparticle could prolong the retention time and preserve the antibiotic activity of amoxicillin in the stomach and help enhance the eradication rate of H. pylori and reduce treatment time. These CAANs, therefore, show potential for the effective treatment of highly antibiotic-resistant H. pylori infection using amoxicillin.

Comparison of the Dual Therapy of Ilaprazole-Amoxicillin and the Bismuth Quadruple Therapy of Ilaprazole-Amoxicillin-Furazolidone-Bismuth Glycyrrhizinate for Eradication of Helicobacter pylori. Front Pharmacol 2022; 13:771876. [PMID: 35571120 PMCID: PMC9094360 DOI: 10.3389/fphar.2022.771876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 01/17/2022] [Indexed: 11/26/2022] Open
Abstract
Objective: The present study aims to compare the safety and efficacy of an amoxicillin/ilaprazole regimen with a bismuth quadruple regimen as the first-line treatment for eradicating Helicobacter pylori (H. pylori) infection. Methods: This was an open-label, randomized, single-center study involving 450 patients with untreated H. pylori infection who were randomly assigned to an Ilaprazole-amoxicillin-furazolidone-bismuth glycyrrhizinate (IAFB) quadruple therapy group for 14 days, a bismuth quadruple therapy group for 10 days, or Ilaprazole-amoxicillin (IA) dual therapy group for 14 days. The 13C urea breath test determined that H. pylori had been eliminated 4–6 weeks after treatment. For patients who failed the first treatment, mucosal tissues (two gastric antrum and one gastric body) were taken under gastroscope for the culture of H. pylori, drug sensitivity, the CYP2C19 gene, and globular degeneration. Results: In the intention-to-treat analysis, the eradication rates of H. pylori in the IAFB-14-day group, the IAFB-10-day group, and the IA-14-day group were 84.0, 79.3, and 88.0%, respectively. In the per-protocol analysis, the eradication rates in the three groups were 94.7, 87.5, and 93.0%, respectively. The resistance rates of patients who failed H. pylori eradication were 68.9% (22/32) for amoxicillin, 90.6% (29/32) for clarithromycin, 68.9% (22/32) for metronidazole, and 87.5% (28/32) for levofloxacin, and the extensive metabolizers of CYP2C19 polymorphism were 59.3% (19/32), the intermediate metabolizers were 34.4% (11/32), and the poor metabolizers were 6.3% (2/32). Conclusion: For newly treated patients with H. pylori infection in China, the efficacy of IA therapy for 14 days was similar to IAFB quadruple therapy for 10 or 14 days with better compliance and less cost. Therefore, these therapies can be considered first-line regimens for empirical treatment. Clinical Trial Registration: [http://www.chictr.org.cn/searchproj.aspx], identifier [ChiCTR2100052308].

Abstract
Aim We compared the efficacy of two different regimens for H. pylori eradication in areas with high antibiotic resistance. Background Helicobacter pylori (H. pylori) is a gram-negative bacillus that has a strong association with chronic gastritis and peptic ulcer disease. Different regimens with varying degrees of effectiveness have been used for H. pylori eradication. Methods The current randomized controlled trial (RCT) randomly assigned 217 patients who had indications for H. pylori eradication therapy to two groups. One group were administered concomitant quadruple therapy (pantoprazole 40 mg, amoxicillin 1 gr, clarithromycin 500 mg, and metronidazole 500 mg every 12 hours) for 14 days, and the second group received 14 days of high-dose dual therapy, consisting of esomeprazole 40 mg BID and amoxicillin 1g TDS. H. pylori eradication was assessed eight weeks after the end of treatment. Results H. pylori eradication rates by PP analysis for 14 days concomitant quadruple therapy and high-dose dual therapy were 88.6% (95% CI, 80.3-92.8) and 82.2% (95% CI, 74.8-89.5), respectively (p = 0.19). According to intention-to-treat (ITT) analysis, the eradication rates were 81.6% (95% CI, 74.5-88.6) and 80.6% (95% CI, 73-88.1), respectively (p = 0.58). Overall drug side effects were 20.8% in high-dose dual therapy and 49.6% in concomitant quadruple therapy (p < 0.001). Conclusion Fourteen days concomitant quadruple therapy can be considered as a relatively acceptable regimen for H. pylori eradication in areas with high clarithromycin and metronidazole resistance. It seems that high-dose dual therapy could be a promising alternative regimen in these areas.

Abstract
BACKGROUND In an era of antibiotic resistance, modified dual therapy has been paid much attention because of simple drug composition and low resistance of amoxicillin. However, its eradication rate as a first-line regimen remains controversial. This study is to evaluate the efficacy and safety of modified dual therapy for the initial treatment of Helicobacter pylori (H. pylori) infection compared with mainstream first-line therapies. METHODS PubMed, the Cochrane Library, and Embase were searched for randomized clinical trials evaluating the efficacy and safety of modified dual therapy as the initial treatment for H. pylori eradication compared with guideline-recommended first-line therapies. A meta-analysis was conducted using Review Manager 5.3 and dichotomous data were estimated by the risk ratio (RR) with the 95% confidence interval (CI). We also performed subgroup analysis according to control groups and studies with antibiotic susceptibility tests. RESULTS Eight studies including 1672 patients with H. pylori infection met the selection criteria and were assessed. The meta-analysis demonstrated that modified dual therapy achieved similar efficacy [85.83% vs. 86.77%, RR 0.99 (95% CI, 0.95-1.03), intention-to-treat analysis; 89.53% vs. 90.45%, RR 0.99 (95% CI, 0.96-1.02), per-protocol analysis] and compliance [95.77% vs. 95.56%, RR 1.00 (95% CI, 0.98-1.02)] compared with recommended first-line regimens. In addition, there were no significant differences in comparing the eradication rate of modified dual therapy with clarithromycin triple therapy, bismuth quadruple therapy, and concomitant therapy, respectively. Subgroup analysis based on the studies with antibiotic susceptibility tests also confirmed a similar efficacy. However, modified dual therapy showed fewer adverse effects [8.70% vs. 22.38%, RR 0.39 (95% CI, 0.28-0.54)], with a significant difference (P<0.00001). CONCLUSION Modified dual therapy achieved equal efficacy and compliance compared with recommended first-line regimens for H. pylori infection, and generally modified dual therapy showed fewer side effects.

Abstract
INTRODUCTION More attention has been paid to the eradication therapy of Helicobactor pylori with the enhancement of health awareness of patients. However, the increasing antibiotic resistance of H. pylori, due to the wide use and abuse of antibiotics, has become a critical factor affecting the efficacy of eradication. To effectively improve the eradication rate of H. pylori, high-dose amoxicillin-proton pump inhibitor (PPI) dual therapy has recently become one of the hot issues. AREAS COVERED The authors review the schemes and efficacy of high-dose amoxicillin-PPI dual therapies in eradication of H. pylori infection. The review indicates that the H. pylori eradication rate of the dual therapy is overall comparable to or better than that of bismuth-containing quadruple therapy or standard triple therapy. It is more effective to administer both amoxicillin and PPI 3-4 times daily for 14 days in the high-dose amoxicillin-PPI dual therapy, and esomeprazole seems to be superior to other PPIs. EXPERT OPINION The high-dose amoxicillin-PPI dual therapy is currently a promising H. pylori eradication regimen in clinical practice, deserving further verification and discussion. Much more attention should be paid to the influence of CYP2C19 polymorphisms and virulence genotyping on H. pylori eradication, and the homogeneity and objectivity of the comparison among different studies.

Abstract
Helicobacter pylori infection is one of the leading causes of several gastroduodenal diseases, such as gastritis, peptic ulcer, and gastric cancer. In fact, H. pylori eradication provides a preventive effect against the incidence of gastric cancer. Amoxicillin is a commonly used antibiotic for H. pylori eradication. However, due to its easy degradation by gastric acid, it is necessary to administer it in a large dosage and to combine it with other antibiotics. This complexity and the strong side effects of H. pylori eradication therapy often lead to treatment failure. In this study, the chitosan/poly (acrylic acid) particles co-loaded with superparamagnetic iron oxide nanoparticles and amoxicillin (SPIO/AMO@PAA/CHI) are used as drug nano-carriers for H. pylori eradication therapy. In vitro and in vivo results show that the designed SPIO/AMO@PAA/CHI nanoparticles are biocompatible and could retain the biofilm inhibition and the bactericidal effect of amoxicillin against H. pylori. Moreover, the mucoadhesive property of chitosan allows SPIO/AMO@PAA/CHI nanoparticles to adhere to the gastric mucus layer and rapidly pass through the mucus layer after exposure to a magnetic field. When PAA is added, it competes with amoxicillin for chitosan, so that amoxicillin is quickly and continuously released between the mucus layer and the gastric epithelium and directly acts on H. pylori. Consequently, the use of this nano-carrier can extend the drug residence time in the stomach, reducing the drug dose and treatment period of H. pylori eradication therapy.

Abstract
BACKGROUND Although 7-day triple therapy, consisting of vonoprazan, amoxicillin (AMO), and clarithromycin (CLA), is recommended for Helicobacter pylori (H. pylori) eradication in adults. However, the importance of reducing antibiotic use in pediatric patients is well recognized. Therefore, our aim was to compare the effectiveness and safety of vonoprazan and AMO (VA) dual therapy to vonoprazan-based (VAC) triple therapy for H. pylori eradication in a cohort of treatment-naïve junior high school students in Japan. METHODS This was a prospective observational study of second-year junior high-school students in Yurihonjo and Nikaho Cities, Japan. Between 2015 and 2017, 161 students were treated with VAC-triple therapy (20 mg vonoprazan, 750 mg AMO, and 200 mg CLA, twice a day for 7 days), while 60 students were treated with VA-dual therapy (20 mg vonoprazan and 750 mg AMO, twice a day for 7 days) since 2018. The success rate of H. pylori eradication and drug-related adverse events were compared between the two therapy groups. Intention-to-treat (ITT) and per-protocol (PP) analyses were performed. RESULTS Groups were comparable at baseline. The ITT and PP eradication rates were 85.0% (95% confidence interval [CI] 75.8-94.2%) and 86.4% (95% CI 77.4-95.5%), respectively, with VA-dual therapy and 82.0% (95% CI 76.0%-87.9%) and 84.1% (95% CI 78.3-89.8%), respectively, with VAC-triple therapy. VA-dual therapy was non-inferior to VAC-triple therapy (ITT, p = 0.018; PP, p = 0.020). The adverse event rate was 10.0% with VA-dual therapy and 19.8% with VAC-triple therapy (p = 0.108). CONCLUSIONS The effectiveness of VA-dual therapy was comparable to that of VAC-triple therapy in H. pylori treatment-naïve junior high school students, while reducing the use of antibiotics.

Abstract
BACKGROUND Helicobacter pylori (HP) infection causes many diseases, such as peptic ulcers, gastritis and gastric cancer, and MALToma. It has been gradually accepted that all HP-infected patients should be treated because HP is regarded as an infection. Therefore, the importance of selecting the optimal treatment regimen has increased. Although the 14-day standard triple therapy (STT) is recommended in the current guidelines, prolonging treatment duration is controversial in real practice because of inconsistent results from previous data and the risk of adverse effects. Additionally, the effect of STT using ilaprazole has not been reported until now. We aimed to compare the eradication rate between 7 and 10 days STT using ilaprazole. METHODS A prospective randomized controlled trial was conducted, which was divided into 2 treatment groups: the control group was 7 days of STT, and the test group was 10 days of STT. The eradication regimen was 10 mg ilaprazole, 500 mg clarithromycin, and 1000 mg amoxicillin twice daily. We included patients who were diagnosed with positive results of H pylori examination. We compared the HP eradication rate according to treatment duration, CYP2C19 subtype and endoscopic diagnosis. RESULTS We enrolled a total of 254 patients consisting of 127 patients in each treatment arm. The eradication rates of the control and test groups were 65.4% (82/127) and 74.8% (95/127), respectively, in the intention-to-treat analysis (P = .1). In the per-protocol analysis, 70.3% (83/118) and 82.6% (94/115) were eradicated in each group, which was statistically significant (P = .027). The CYP2C19 subtype was examined in 230 patients. The eradication rate was 79.2% (57/72), 75.4% (92/122), and 72.2% (26/36) in each group, which was not significantly different (P = .704). CONCLUSION Ten-day STT was more effective than 7-day STT for HP eradication. The eradication rate was not affected by the CYP2C19 genotype.

Abstract
As antibiotic resistance rates increase, Helicobacter pylori (H. pylori) eradication regimens are constantly being updated. Quadruple therapy with bismuth is currently the main empirical eradication regimen. However, long-term use of multiple antibiotics will enhance the resistance to them. Therefore, there is a need for a new regimen to eliminate H. pylori and reduce antibiotics used to prevent further resistance. High-dose dual therapy (HDDT) with a proton pump inhibitor and amoxicillin may be a breakthrough in eradicating H. pylori. Current research shows that HDDT, as a first-line regimen or rescue regimen, has an eradication rate comparable to quadruple therapy with a low incidence of adverse events, and the use of a single antibiotic greatly reduces the occurrence of antibiotic resistance.

Abstract
AIM To compare the efficacy and safety between modified quadruple- and bismuth-containing quadruple therapy as first-line eradication regimen for Helicobacter pylori infection. METHODS This study was a multicenter, randomized-controlled, non-inferiority trial. Subjects endoscopically diagnosed with H. pylori infection were randomly allocated to receive modified quadruple- (rabeprazole 20 mg bid, amoxicillin 1 g bid, metronidazole 500 mg tid, bismuth subcitrate 300 mg qid [elemental bismuth 480 mg]; PAMB) or bismuth-containing quadruple therapy (rabeprazole 20 mg bid, bismuth subcitrate 300 mg qid, metronidazole 500 mg tid, tetracycline 500 mg qid; PBMT) for 14 days. Rates of eradication success and adverse events were investigated. Antibiotic resistance was determined using the agar dilution and DNA sequencing of the clarithromycin resistance point mutations in the 23 S rRNA gene of H. pylori. RESULTS In total, 233 participants were randomized, 27 were lost to follow-up, and four violated the protocol. Both regimens showed an acceptable eradication rate in the intention-to-treat (PAMB: 87.2% vs. PBMT: 82.8%, P = .37), modified intention-to-treat (96.2% vs. 96%, P > .99), and per-protocol (96.2% vs. 96.9%, P > .99) analyses. Non-inferiority in the eradication success between PAMB and PBMT was confirmed. The amoxicillin-, metronidazole-, tetracycline-, clarithromycin-, and levofloxacin-resistance rates were 8.3, 40, 9.4, 23.5, and 42.2%, respectively. Antimicrobial resistance did not significantly affect the efficacy of either therapy. Overall compliance was 98.1%. Adverse events were not significantly different between the two therapies. CONCLUSION Modified quadruple therapy comprising rabeprazole, amoxicillin, metronidazole, and bismuth is an effective first-line treatment for the H. pylori infection in regions with high clarithromycin and metronidazole resistance.

Gao CP, Zhang D, Zhang T, Wang JX, Han SX, Graham DY, Lu H. PPI-amoxicillin dual therapy for Helicobacter pylori infection: An update based on a systematic review and meta-analysis. Helicobacter 2020; 25:e12692. [PMID: 32314468 DOI: 10.1111/hel.12692] [Citation(s) in RCA: 48] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2019] [Revised: 02/27/2020] [Accepted: 03/03/2020] [Indexed: 01/30/2023]
Abstract
BACKGROUND AND AIMS The efficacy of PPI-amoxicillin dual therapy (high-dose dual therapy) in the eradication of Helicobacter pylori is controversial. We aimed to investigate whether PPI-amoxicillin dual therapy is effective. METHODS We searched several publication databases for randomized controlled trials (RCTs) that compared PPI-amoxicillin dual therapy with controls up to March 2019. Meta-analyses of eradication rates were performed using random-effects models. RESULTS Data from twelve RCTs including 2249 patients suggested that PPI-amoxicillin dual therapy and the current mainstream guidelines-recommended therapies achieved similar efficacy (83.2% vs 85.3%, risk ratio [RR]: 1.00, 95% CI 0.97-1.03, intention-to-treat analysis), (87.5% vs 90.1%, RR: 0.98, 95% CI 0.95-1.02, per-protocol analysis), and compliance (94.3% vs 93.5%, RR: 1.11, 95% CI 0.78-1.59), but side effects were less likely in the dual therapy (12.9% vs 28.0%, RR: 0.53, 95% CI 0.37-0.76). Further subgroup analyses showed that the seven RCTs (1302 patients) that reported antimicrobial susceptibility test results also showed that PPI-amoxicillin dual therapy and the current guidelines-recommended therapies achieved similar efficacy, and PPI-amoxicillin dual therapy was as effective for rescue therapy (RR: 0.97, 95% CI 0.89-1.05) as for first-line treatment (RR: 0.97, 95% CI 0.93-1.02). CONCLUSIONS Compared with the current mainstream guidelines-recommended therapies, PPI-amoxicillin dual therapy has the same efficacy and compliance, and generally PPI-amoxicillin dual therapy causes fewer side effects.

Abstract
BACKGROUND The first-line eradication rate of standard triple therapy for Helicobacter pylori infection has declined to <80%, and alternative therapies with >90% success rates are needed. Inconsistent eradication rates were reported for proton pump inhibitor- and amoxicillin-containing high-dose dual therapy. OBJECTIVES We performed a prospective, randomized controlled study to assess the efficacy of esomeprazole- and amoxicillin-containing high-dose dual therapy and investigated the influencing clinical factors. PATIENTS AND METHODS We recruited 240/278 eligible H. pylori-infected patients after exclusion. They were randomly assigned to 14 day high-dose dual therapy (esomeprazole 40 mg three times daily and amoxicillin 750 mg four times daily for 14 days; EA group) or 7 day non-bismuth quadruple therapy (esomeprazole 40 mg twice daily, clarithromycin 500 mg twice daily, amoxicillin 1 g twice daily and metronidazole 500 mg twice daily for 7 days; EACM group). Urea breath tests were followed up 8 weeks later. RESULTS The eradication rates for the EA and EACM groups were 91.7% (95% CI = 85.3%-96.0%) and 86.7% (95% CI = 79.3%-92.2%) (P = 0.21) in ITT analysis; and 95.7% (95% CI = 90.2%-98.6%) and 92.0% (95% CI = 85.4%-96.3%) (P = 0.26) in PP analysis. The adverse event rates were 9.6% versus 23.0% in the two groups (P = 0.01). The H. pylori culture positivity rate was 91.8%. The antibiotic resistance rates were amoxicillin, 0%; clarithromycin, 14.6%; and metronidazole, 33.7%. CONCLUSIONS A 14 day esomeprazole- and amoxicillin-containing high-dose dual therapy achieves a high eradication rate as first-line anti-H. pylori therapy, comparable to that with 7 day non-bismuth quadruple therapy but with fewer adverse events.

Abstract
As one of the most prevalent infections globally, Helicobacter pylori (H. pylori) continues to present diagnostic and therapeutic challenges for clinicians worldwide. Diagnostically, the "test-and-treat" strategy is the recommended approach for healthcare practitioners when managing this potentially curable disease. The choice of testing method should be based on several factors including patient age, presenting symptoms, and medication use, as well as test reliability, availability, and cost. With rising antibiotic resistance, particularly of macrolides, care must be taken to ensure that therapy is selected based on regional resistance patterns and prior antibiotic exposure. In the USA, macrolide antibiotic resistance rates in some areas have reached or exceeded a generally accepted threshold, such that clarithromycin triple therapy may no longer be an appropriate first-line empiric treatment. Instead, bismuth quadruple therapy should be considered, while levofloxacin-based or alternative macrolide-containing therapies are also options. Once treated, it is essential to test for eradication as untreated H. pylori is associated with serious complications including peptic ulcer disease, mucosa-associated lymphoid tissue lymphoma, and gastric cancer. This review article aims to consolidate current knowledge of H. pylori infection with a particular emphasis on diagnostic and treatment strategies.

Leja M, Dumpis U. What Would the Screen-and-Treat Strategy for Helicobacter pylori Mean in Terms of Antibiotic Consumption? Dig Dis Sci 2020; 65:1632-1642. [PMID: 31659615 PMCID: PMC7224010 DOI: 10.1007/s10620-019-05893-z] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Accepted: 10/03/2019] [Indexed: 02/08/2023]
Abstract
Several guidelines recommend the screen-and-treat strategy, i.e. active search for the presence of Helicobacter pylori infection and its eradication to prevent the possibility of gastric cancer. It is thought that a relatively short duration antibiotic regimen given once in a lifetime would not significantly increase overall antibiotic consumption. However, this would mean offering antibiotic treatment to the majority of the population in countries with the biggest burden of gastric cancer who would, therefore, have the greatest benefit from such a strategy. So far, no country has implemented an eradication strategy. With an example based on the current situation in Latvia, we have estimated the increase in antibiotic consumption if the screen-and-treat strategy was applied. Depending on the scenario that might be chosen, clarithromycin consumption would increase up to sixfold, and amoxicillin consumption would double if the recommendations of the current guideline in the local circumstances was applied. It appears that an increase in commonly used antibiotic consumption cannot be justified from the viewpoint of antibiotic stewardship policies. Solutions to this problem could be the use of antibiotics that are not required for treating life-threatening diseases or more narrow selection of the target group, e.g. young people before family planning to avoid transmission to offspring. Additional costs related to the increase in resistome should be considered for future cost-effectiveness modelling of the screen-and-treat strategy.

[PMID: 31111580 DOI: 10.1111/hel.12596] [Citation(s) in RCA: 50] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Revised: 03/23/2019] [Accepted: 04/06/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND A reliably highly effective high-dose proton-pump inhibitor plus amoxicillin (dual Helicobacter pylori therapy) has remained elusive. We compared whether the addition of bismuth to high-dose dual therapy would improve the efficacy of high-dose dual therapy as first-line treatment. METHODS This was an open-label, randomized single-center study of 160 treatment-naive patients with H. pylori infection who were randomly assigned to 14-day therapy with esomeprazole 40 mg twice a day plus amoxicillin 1 g three times a day with or without bismuth potassium citrate 600 mg (elemental bismuth 220 mg) twice a day. Antibiotic resistance was determined by agar dilution method and eradication by 13 C-urea breath test. RESULTS The per-protocol eradication rates were 96.1%; 95% CI = 88.9%-99.2% (73/76) without bismuth vs 93.3%; 95% CI = 85.1%-97.8% (70/75) with bismuth (P = 0.494). The intention-to-treat eradication rates were 92.5%; 95% CI = 84.4%-97.2% (74/80) without bismuth and 88.8%; 95% CI = 79.7%-94.7% (71/80) with bismuth (P = 0.416). Resistance to amoxicillin, clarithromycin, metronidazole, and levofloxacin was 0%, 31.7%, 81.4%, and 40.7%, respectively. Smoking reduced treatment effectiveness limited to those not receiving bismuth. The per-protocol eradication rates were 70% (7/10) vs 100% (66/66) in smokers vs non-smokers without bismuth (P = 0.002), and 100% (10/10) in smokers vs 92.3% (60/65) in non-smokers with bismuth (P = 1.0). The adverse event rates were 7.5% (6/80) without bismuth vs 11.3% (9/80) with bismuth (P = 0.416). CONCLUSIONS Fourteen-day high-dose dual therapy was both effective and safe for first-line treatment in a region of high prevalence antibiotic resistance. Adding bismuth only improved treatment effectiveness among smokers.

Abstract
OBJECTIVES This study assessed the effectiveness, adverse events, patient adherence, and costs of modified dual therapy compared with bismuth-containing quadruple therapy for treating Helicobacter pylori infection in Chinese patients. We also sought to determine whether modified dual therapy could be used as an alternative first-line treatment for H. pylori infection. METHODS A total of 232 H. pylori-infected, treatment-naive patients were enrolled in this open-label, randomized controlled clinical trial. Patients were randomly allocated into 2 groups: the 14-day modified dual therapy group and the bismuth-containing quadruple therapy group. Eradication rates, drug-related adverse events, patient compliance, and drug costs were compared between the 2 groups. RESULTS The modified dual therapy group achieved eradication rates of 87.9%, 91.1%, and 91.1% as determined by the intention-to-treat, per-protocol, and modified intention-to-treat analyses, respectively. The eradication rates were similar compared with the bismuth-containing quadruple therapy group: 89.7%, 91.2%, and 90.4%. In addition, modified dual therapy ameliorated variations in the CYP2C19, IL-1B-511, and H. pylori VacA genotypes. There were no significant differences in the compliance rates between the 2 groups. The modified dual therapy group exhibited significantly less overall side effects compared with the bismuth-containing quadruple therapy group (P < 0.001). Furthermore, the cost of medications in the modified dual therapy was lower compared with that in the bismuth-containing quadruple therapy. CONCLUSIONS Modified dual therapy at high dose and administration frequency is equally effective and safer and less costly compared with bismuth-containing quadruple therapy.

Abstract
Helicobacter pylori is one of the most common human pathogens and it has been estimated that about 50% of the world's population is currently infected. The present consensus is that, unless there are compelling reasons, all H. pylori infections should be cured. Since the 1990s, different national and international guidelines for the management of H. pylori-related diseases have been published and periodically updated regarding indications for treatment, diagnostic procedures, and preferred treatment regimens. Most guidelines provide sophisticated meta-analyses examining the outcome of different regimens done in regions with variable, often high rates of resistance to antibiotics, for which the prevalence and effects of resistance was often ignored. Although successful antimicrobial therapy must be susceptibility-based, increasing antimicrobial resistance and general unavailability of susceptibility testing have required clinicians to generally rely on empiric regimens. Antibiotics resistance of H. pylori has reached alarming high levels worldwide, which has an effect to efficacy of treatment. The recommendations should provide regimes for multi-resistant infections or for those where susceptibility testing is unavailable or refused. The first rule is to use only proven locally effective therapies. Because of patient intolerances, drug allergies, and local experiences, the clinicians should have at least two options for first-line therapy. As with any antimicrobial therapy, a thorough review of prior antibiotic use is invaluable to identify the presence of probably resistance. The second key is patient education regarding potential and expected side-effects and the importance of completing the course of antibiotics. We also review here triple therapies, sequential-concomitant, hybrid therapies, bismuth therapies, dual therapy, vonoprazan, modern antibiotic treatments, probiotics and vaccination.

Abstract
This review summarizes important studies regarding Helicobacter pylori therapy published from April 2016 to April 2017. The main themes that emerge involve studies assessing the efficacy of bismuth and nonbismuth quadruple regimens. While in recent years, much of the emphasis on the use of bismuth has focussed on its utility in a second-line setting, an increasing number of studies this year have shown excellent efficacy in first-line therapy. The efficacy of bismuth as a second-line after sequential and concomitant therapy was particularly noteworthy. Antibiotic resistance was more intensely studied this year than for a long time, and definite trends are presented regarding an increase in resistance, including the fact that clarithromycin resistance in particular is now at a level where the continued use of clarithromycin triple therapy first-line as a mainstream treatment is not recommended. Another exciting trend to emerge this year is the utility of vonoprazan as an alternative to PPI therapy, especially in resistant and difficult-to-treat groups.

Abstract
Because the prevalence of antibiotic resistance markedly increases with time worldwide, anti-H. pylori treatment is continuing to be a great challenge forsphysicians in clinical practice. The Real-world Practice & Expectation of Asia-Pacific Physicians and Patients in Helicobacter Pylori Eradication (REAP-HP) Survey demonstrated that the accepted minimal eradication rate of anti-H. pylori regimen in H. pylori-infected patients was 91%. The Kyoto Consensus Report on Helicobacter Pylori Gastritis also recommended that, within any region, only regimens which reliably produce eradication rates of ≥90% in that population should be used for empirical treatment. This article is aimed to review current first-line eradication regimens with a per-protocol eradication rate exceeding 90% in most geographic areas. In regions with low (≦15%) clarithromycin resistance, 14-day hybrid (or reverse hybrid), 10 ~ 14-day sequential, 7 ~ 14-day concomitant, 10 ~ 14-day bismuth quadruple or 14-day triple therapy can achieve a high eradication rate in the first-line treatment of H. pylori infection. However, in areas with high (>15%) clarithromycin resistance, standard triple therapy should be abandoned because of low eradication efficacy, and 14-day hybrid (or reverse hybrid), 10 ~ 14-day concomitant or 10 ~ 14-day bismuth quadruple therapy are the recommended regimens. If no recent data of local antibiotic resistances of H. pylori strains are available, universal high efficacy regimens such as 14-day hybrid (or reverse hybrid), concomitant or bismuth quadruple therapy can be adopted to meet the recommendation of consensus report and patients’ expectation.

Hu Y, Zhu Y, Lu NH. Novel and Effective Therapeutic Regimens for Helicobacter pylori in an Era of Increasing Antibiotic Resistance. Front Cell Infect Microbiol 2017; 7:168. [PMID: 28529929 PMCID: PMC5418237 DOI: 10.3389/fcimb.2017.00168] [Citation(s) in RCA: 89] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2016] [Accepted: 04/18/2017] [Indexed: 01/06/2023] Open
Abstract
Helicobacter pylori (H. pylori) is a common gastrointestinal bacterial strain closely associated with the incidence of chronic gastritis, peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. A current research and clinical challenge is the increased rate of antibiotic resistance in H. pylori, which has led to a decreased H. pylori eradication rate. In this article, we review recent H. pylori infection and reinfection rates and H. pylori resistance to antibiotics, and we discuss the pertinent treatments. A PubMed literature search was performed using the following keywords: Helicobacter pylori, infection, reinfection, antibiotic resistance, bismuth, proton pump inhibitors, vonoprazan, susceptibility, quintuple therapy, dual therapy, and probiotic. The prevalence of H. pylori has remained high in some areas despite the decreasing trend of H. pylori prevalence observed over time. Additionally, the H. pylori reinfection rate has varied in different countries due to socioeconomic and hygienic conditions. Helicobacter pylori monoresistance to clarithromycin, metronidazole or levofloxacin was common in most countries. However, the prevalence of amoxicillin and tetracycline resistance has remained low. Because H. pylori infection and reinfection present serious challenges and because H. pylori resistance to clarithromycin, metronidazole or levofloxacin remains high in most countries, the selection of an efficient regimen to eradicate H. pylori is critical. Currently, bismuth-containing quadruple therapies still achieve high eradication rates. Moreover, susceptibility-based therapies are alternatives because they may avoid the use of unnecessary antibiotics. Novel regimens, e.g., vonoprazan-containing triple therapies, quintuple therapies, high-dose dual therapies, and standard triple therapies with probiotics, require further studies concerning their efficiency and safety for treating H. pylori.
