Abstract
PURPOSE OF THE REVIEW Acid suppression with proton pump inhibitors (PPIs) represents the standard of care in the treatment of acid-related diseases. However, despite their effectiveness, PPIs display some intrinsic limitations, which underlie the unmet clinical needs that have been identified over the past decades. The aims of this review are to summarize the current status and future development of the new class of antisecretory drugs (potassium-competitive acid blockers, P-CABs) that have recently been introduced into medical practice. RECENT FINDINGS Over the past decades, clinical needs unmet by the current acid suppressants have been recognized, especially in the management of patients with GERD, Helicobacter pylori infection and NSAID-related peptic ulcer. The failure to address these needs is mainly due to their inability to achieve a consistent acid suppression in all patients and, particularly, to control nighttime acidity. It was then realized that an extended duration of acid suppression would exert additional benefits. The available data with P-CABs show that they are able to address these unmet clinical needs. Four different P-CABs (vonoprazan, tegoprazan, fexuprazan and keverprazan) are currently available. However, only two of them are approved outside Asia. Vonoprazan is available in North, Central and South America while tegoprazan is marketed only in Latin American countries. Two other compounds (namely linazapran glurate and zestaprazan) are presently under clinical development. While clinical trials on GERD have been performed with all P-CABs, only vonoprazan and tegoprazan have been investigated as components of Helicobacter pylori eradication regimens. The available data show that-in the above two clinical indications-P-CABs provide similar or better efficacy in comparison with PPIs. Their safety in the short-term overlaps that of PPIs, but data from long-term treatment are needed.

Abstract
Background and Objectives The success rate of Helicobacter pylori (H. pylori) eradication in China is declining. The aim of this study was to evaluate eradication outcomes in clinical practice and identifies factors contributing to treatment failure. Methods A retrospective review was conducted on patients treated for H. pylori infection with 14-day bismuth-containing quadruple therapy at a Beijing medical center from January 2020 to December 2023. We analyzed demographic and clinical data, eradication rates across regimens, and performed multivariate analysis to pinpoint predictors of failure. Results Out of 3340 participants, 2273 (68.1%) achieved eradication. Amoxicillin-based combinations (69.2%) outperformed other antibiotic regimens (58.9%, p < 0.001), with amoxicillin plus doxycycline reaching a 71.4% success rate. Esomeprazole-based regimens were more effective (73.6%) than other PPI regimens (65.2%, p = 0.001), notably, a rabeprazole, amoxicillin, doxycycline, and bismuth combination had an 80.0% success rate. Age, gender, and smoking and drinking were significant eradication failure predictors. Conclusion In real-world settings, 14-day amoxicillin and esomeprazole-based quadruple regimens have been demonstrated to be more effective than other regimens. Age, gender, and lifestyle habits are identified as independent risk factors for eradication failure. Registration This study was registered in the Chinese Clinical Trial Registry on 08/01/2024 (clinical trial registration number: ChiCTR2400079647).

Vonoprazan-Amoxicillin Dual Therapy With Different Amoxicillin Administration Regimens for Helicobacter pylori Treatment: A Randomized Controlled Trial. Helicobacter 2024; 29:e13118. [PMID: 39087868 DOI: 10.1111/hel.13118] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/17/2024] [Accepted: 07/20/2024] [Indexed: 08/02/2024]
Abstract
BACKGROUND The effect of preprandial or postprandial administration of amoxicillin on the efficacy of vonoprazan-amoxicillin dual therapy (VA-dual therapy) for Helicobacter pylori treatment has not been studied. It is also unclear whether amoxicillin dosing four times daily is more effective than three times daily. We aimed to investigate the effect of different amoxicillin administration regimens on the efficacy of VA-dual therapy. MATERIALS AND METHODS H. pylori-infected subjects were randomly assigned to three groups in a 1:1:1 ratio to receive a 14-day dual therapy consisting of vonoprazan 20 mg twice daily + amoxicillin 1000 mg three times daily before meals (BM-TID) or 1000 mg three times daily after meals (AM-TID) or 750 mg four times daily after meals (AM-QID). H. pylori eradication rates, adverse events rates, compliance, and antibiotic resistance were compared. RESULTS Between May 2021 to April 2023, 327 subjects were enrolled. The eradication rates of BM-TID, AM-TID, and AM-QID dual therapy were 88.1%, 89.9%, and 93.6% in intention-to-treat (ITT) analysis, 90.6%, 94.2%, and 99.0% in modified ITT (MITT) analysis, and 90.4%, 94.1%, and 99.0% in per-protocol (PP) analysis. Although there was non-inferiority between BM-TID and AM-TID, as well as between AM-TID and AM-QID, AM-QID was significantly more effective than BM-TID. There were no significant differences in adverse event rates, compliance, and antibiotic resistance among the three groups. CONCLUSIONS Postprandial administration and the increased frequency of administration of amoxicillin may contribute to a better efficacy of VA-dual therapy, especially for rescue therapy. All VA-dual therapy in our study could achieve good efficacy for first-line treatment. TRIAL REGISTRATION clinicaltrials.gov: NCT05901051.

Abstract
Helicobacter pylori (H. pylori) is a strict microaerophilic bacterial species that exists in the stomach, and H. pylori infection is one of the most common chronic bacterial infections affecting humans. Eradicating H. pylori is the preferred method for the long-term prevention of complications such as chronic gastritis, peptic ulcers, gastric mucosa-associated lymphoid tissue lymphoma, and gastric cancer. However, first-line treatment with triple therapy and quadruple therapy has been unable to cope with increasing antibacterial resistance. To provide an updated review of H. pylori infections and antibacterial resistance, as well as related treatment options, we searched PubMed for articles published until March 2024. The key search terms were "H. pylori", "H. pylori infection", "H. pylori diseases", "H. pylori eradication", and "H. pylori antibacterial resistance." Despite the use of antimicrobial agents, the annual decline in the eradication rate of H. pylori continues. Emerging eradication therapies, such as the development of the new strong acid blocker vonoprazan, probiotic adjuvant therapy, and H. pylori vaccine therapy, are exciting. However, the effectiveness of these treatments needs to be further evaluated. It is worth mentioning that the idea of altering the oxygen environment in gastric juice for H. pylori to not be able to survive is a hot topic that should be considered in new eradication plans. Various strategies for eradicating H. pylori, including antibacterials, vaccines, probiotics, and biomaterials, are continuously evolving. A novel approach involving the alteration of the oxygen concentration within the growth environment of H. pylori has emerged as a promising eradication strategy.

Helicobacter pylori: High dose amoxicillin does not improve primary or secondary eradication rates in an Irish cohort. World J Clin Cases 2024; 12:2773-2779. [PMID: 38899284 PMCID: PMC11185322 DOI: 10.12998/wjcc.v12.i16.2773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Revised: 02/08/2024] [Accepted: 04/07/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND Helicobacter pylori (H. pylori) eradication rates have fallen globally, likely in large part due to increasing antibiotic resistance to traditional therapy. In areas of high clarithromycin and metronidazole resistance such as ours, Maastricht VI guidelines suggest high dose amoxicillin dual therapy (HDADT) can be considered, subject to evidence for local efficacy. In this study we assess efficacy of HDADT therapy for H. pylori eradication in an Irish cohort. AIM To assess the efficacy of HDADT therapy for H. pylori eradication in an Irish cohort as both first line, and subsequent therapy for patients diagnosed with H. pylori. METHODS All patients testing positive for H. pylori in a tertiary centre were treated prospectively with HDADT (amoxicillin 1 g tid and esomeprazole 40 mg bid × 14 d) over a period of 8 months. Eradication was confirmed with Urea Breath Test at least 4 wk after cessation of therapy. A delta-over-baseline > 4% was considered positive. Patient demographics and treatment outcomes were recorded, analysed and controlled for basic demographics and prior H. pylori treatment. RESULTS One hundred and ninety-eight patients were identified with H. pylori infection, 10 patients were excluded due to penicillin allergy and 38 patients refused follow up testing. In all 139 were included in the analysis, 55% (n = 76) were female, mean age was 46.6 years. Overall, 93 (67%) of patients were treatment-naïve and 46 (33%) had received at least one previous course of treatment. The groups were statistically similar. Self-reported compliance with HDADT was 97%, mild side-effects occurred in 7%. There were no serious adverse drug reactions. Overall the eradication rate for our cohort was 56% (78/139). Eradication rates were worse for those with previous treatment [43% (20/46) vs 62% (58/93), P = 0.0458, odds ratio = 2.15]. Age and Gender had no effect on eradication status. CONCLUSION Overall eradication rates with HDADT were disappointing. Despite being a simple and possibly better tolerated regime, these results do not support its routine use in a high dual resistance country. Further investigation of other regimens to achieve the > 90% eradication target is needed.

Abstract
We conducted this study to systematically review and assess the current clinical practice guidelines (CPGs) related to the diagnosis and treatment of Helicobacter pylori (H. pylori) infection. The aim was to evaluate the quality of these included CPGs and provide clinicians with a convenient and comprehensive reference for updating their own CPGs. We searched four databases to identify eligible CPGs focusing on H. pylori diagnosis and treatment recommendations. The results were presented using evidence mappings. Quality and clinical applicability were assessed comprehensively using AGREE-II and AGREE-REX. Statistical tests, specifically Bonferroni tests, were employed to compare the quality between evidence-based guidelines and consensus. A total of 30 eligible CPGs were included, comprising 17 consensuses and 13 guidelines. The quality showed no statistical significance between consensuses and guidelines, mainly within the moderate to low range. Notably, recommendations across CPGs exhibited inconsistency. Nevertheless, concerning diagnosis, the urea breath test emerged as the most frequently recommended method for testing H. pylori. Regarding treatment, bismuth quadruple therapy stood out as the predominantly recommended eradication strategy, with high-dose dual therapy being a newly recommended option. Our findings suggest the need for specific organizations to update their CPGs on H. pylori or refer to recently published CPGs. Specifically, CPGs for pediatric cases require improvement and updating, while a notable absence of CPGs for the elderly was observed. Furthermore, there is a pressing need to improve the overall quality of CPGs related to H. pylori. Regarding recommendations, additional evidence is essential to elucidate the relationship between H. pylori infection and other diseases and refine test indications. Clinicians are encouraged to consider bismuth quadruple or high-dose dual therapy, incorporating locally sensitive antibiotics, as empirical radical therapy. .

Abstract
INTRODUCTION Helicobacter pylori (H. pylori), the most prevalent chronic infection globally, is the major cause of relevant diseases such as gastric cancer, leading to high morbidity and mortality worldwide. Several studies have focused on optimize H. pylori eradication treatment through combination therapies and antibiotic resistance. However, the adverse events profile and its impact, as a primary outcome, remains underexplored.The aim of this review was to summarize the available data on the safety of the most common regimens for H. pylori eradication and its impact on the compliance. AREAS COVERED This review encompassed the published evidence from the years 2008 to 2023 regarding both the safety and compliance for most common H. pylori eradication regimens. The main sources for this review comprised MEDLINE, PubMed, and Cochrane electronic databases. Furthermore, it included a safety analysis of unpublished data from the European Registry on H. pylori management (Hp-EuReg). EXPERT OPINION Poor compliance is correlated with significantly lower cure rates, and this is a unique modifiable source of H. pylori treatment failure. Eradication treatments have become complex, involving multiple drugs and dosing intervals. Thus, patient education is crucial; doctors must explain to the patient about potential temporary and most often harmless side effects.

Abstract
INTRODUCTION In Chile, more than 70% of adults are infected by Helicobacter pylori. Clarithromycin should not be used in any regimen if there is >15% resistance to this antibiotic, being greater than 26% in our population. In this scenario, the effectiveness of triple therapy (proton pump inhibitor [PPI], clarithromycin, amoxicillin) was only 63.8%. AIM To evaluate the eradication rate and safety of dual therapy (esomeprazole and amoxicillin) in high doses, through a prospective, observational, and descriptive study. METHODS Patients with a positive urease test obtained in an upper digestive endoscopy were included. Any other previous H. pylori eradication regimen were excluded. All patients were treated with esomeprazole 40 mg three times a day and amoxicillin 750 mg four times a day for 14 days. The eradication rate of the dual therapy was evaluated with the H. pylori stool antigen test (the Pylori-Strip® test used) 6 weeks after completing the eradication treatment and with at least 14 days without PPI, being a negative result, confirmation of the effectiveness of this regimen. RESULTS Of 122 patients, 106 had a negative H. pylori antigen in stool; The intention-to-treat and per protocol analysis, the eradication rates were 91.8% [95% CI: 87%-97%] and 94% [95% CI: 90%-98%], respectively. Four patients discontinued treatment due to adverse effects. Smoking and adherence to treatment were associated with eradication rate. CONCLUSIONS In this cohort of patients with H. pylori infection, high-dose dual therapy has a high eradication rate and good adherence, raising the possibility that it could be used as first-line therapy in our country. Studies with a larger number of patients should confirm these results.

Abstract
Background: Until now, there have been no randomized controlled trials directly evaluating the efficacy of high-dose ilaprazole-amoxicillin dual therapy (HT) in comparison to other standard treatments for H. pylori (Helicobacter pylori) infection. This study aimed to compare the effectiveness and safety of HT with bismuth quadruple therapy (BQT) as an initial treatment for H. pylori. Methods: This single-center, prospective, randomized clinical controlled trial recruited 225 consecutive patients. They were assigned to either HT group (ilaprazole, 10 mg, twice daily; amoxicillin 1,000 mg, three times daily) or BQT group (compound bismuth aluminate granules, 2.6 g, three times daily; ilaprazole, 5 mg, twice daily; amoxicillin, 1,000 mg, twice daily; clarithromycin, 500 mg, twice daily) for 14 days. The 13C-urea breath test assessed eradication success 4 weeks after treatment. The primary outcome focused on the eradication rate, with secondary outcomes including safety and compliance. Results: From February 2023 to March 2023, 228 subjects were screened, and 225 were randomized. The HT and BQT groups showed eradication rates of 76.3% and 61.3% (p = 0.015) both by intention-to-treat (ITT) analysis and per-protocol (PP) analysis. HT was associated with fewer adverse events than BQT (27.2% vs. 81.8%, p = 0.002). The most commonly reported adverse events was bitter taste of mouth (3.5% vs. 60.4%, p < 0.001). There was no significant difference in compliance between the two groups (89.5% vs. 92.8%, p = 0.264). Conclusion: The 14-day HT treatment demonstrates better efficacy in H. pylori eradication treatment and improved safety and compliance compared to BQT. The results provide supporting evidence for 14-day HT can be potentially considered as a first-line regimen for empirical treatment.

Abstract
Helicobacter pylori, a gram-negative microaerophilic pathogen, causes several upper gastrointestinal diseases, such as chronic gastritis, peptic ulcer disease, and gastric cancer. For the diseases listed above, H. pylori has different pathogenic mechanisms, including colonization and virulence factor expression. It is essential to make accurate diagnoses and provide patients with effective treatment to achieve positive clinical outcomes. Detection of H. pylori can be accomplished invasively and noninvasively, with both having advantages and limitations. To enhance therapeutic outcomes, novel therapeutic regimens, as well as adjunctive therapies with probiotics and traditional Chinese medicine, have been attempted along with traditional empiric treatments, such as triple and bismuth quadruple therapies. An H. pylori infection, however, is difficult to eradicate during treatment owing to bacterial resistance, and there is no commonly available preventive vaccine. The purpose of this review is to provide an overview of our understanding of H. pylori infections and to highlight current treatment and diagnostic options.

Abstract
Helicobacter pylori remains a major health problem worldwide, causing considerable morbidity and mortality due to peptic ulcer disease and gastric cancer. These guidelines constitute an update of the previous "Recommendations on the diagnosis and management of Helicobacter pylori infection" issued in 2014. They have been developed by a Task Force organized by the Governing Board of the Polish Society of Gastroenterology. They discuss, with particular emphasis on new scientific data covering papers published since 2014: the epidemiology, clinical presentation, diagnostic principles and criteria for the diagnosis, and recommendations for the treatment of H. pylori infection. The guidelines in particular determine which patients need to be tested and treated for infection. The Task Force also discussed recommended treatment algorithms. Accordingly, a combination of available evidence and consensus-based expert opinion were used to develop these best practice advice statements. It is worth noting that guidelines are not mandatory to implement but they offer advice for pragmatic, relevant and achievable diagnostic and treatment pathways based on established key treatment principles and using local knowledge and available resources to guide regional practice.

Abstract
Helicobacter pylori infection is an important issue worldwide, and several guidelines have been published for clinicians to achieve successful eradication. However, there are still some patients who remain infected with H. pylori after treatment. Clinicians should identify the reasons that caused treatment failure and find strategies to manage them. We have searched and organized the literature and developed methods to overcome factors that contribute to prior treatment failure, such as poor compliance, inadequate intragastric acid suppression, and antibiotic resistance. To improve compliance, telemedicine or smartphone applications might play a role in the modern world by increasing doctor-patient relationships, while concomitant probiotics could be administered to reduce adverse effects and enhance adherence. For better acid suppression, high-potency and high-dose proton-pump inhibitors or potassium-competitive acid blockers have preferable efficacy. To overcome antibiotic resistance, susceptibility tests either by culture or by genotyping are the most commonly used methods and have been suggested for antibiotic selection before rescue therapy, but empirical therapy according to detailed medical history could be an alternative. Eradication with a longer treatment period (14 days) has a better outcome than shorter period (7 or 10 days). Ultimately, clinicians should select antibiotics based on the patient's history of drug allergy, previous antibiotic exposure, local antibiotic resistance, available medications, and cost. In addition, identifying patients with a high risk of cancer and shared decision-making are also essential for those who have experienced eradication failure.

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.

[PMID: 37015201 PMCID: PMC10407836 DOI: 10.1159/000529622] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/25/2022] [Accepted: 11/27/2022] [Indexed: 04/06/2023]
Abstract
INTRODUCTION Vonoprazan, a novel potassium-competitive acid blocker, has a strong acid suppression effect and potent efficacy in acid-associated diseases, including Helicobacter pylori eradication. We performed a systematic review and meta-analysis to investigate the efficacy and safety of vonoprazan/amoxicillin dual therapy for H. pylori eradication. METHODS We conducted a systematic literature search through PubMed, Web of Science, EMBASE, and the Cochrane Library up to June 2022, to identify randomized controlled trials and cohort studies comparing vonoprazan/amoxicillin dual therapy and triple therapies for H. pylori eradication. Primary outcomes were cure rates and relative efficacy. Secondary outcomes included adverse events, dropout rate, and subgroup analysis. RESULTS Five studies with 1,852 patients were included in the analysis. The cure rates of vonoprazan/amoxicillin dual therapy were 85.6% with 95% confidence interval (CI) of 79.7-91.5% and 88.5% (95% CI: 83.2-93.8%) in the intention-to-treat and per-protocol analyses. The efficacy of vonoprazan/amoxicillin dual therapy was not inferior to that of triple therapy with pooled risk ratio (RR) of 1.03 (95% CI: 0.97-1.10) and 1.02 (95% CI: 0.98-1.08) in intention-to-treat and per-protocol analyses; while it was significantly superior to the omeprazole or lansoprazole-based triple therapy (RR = 1.15, 95% CI: 1.05-1.25, p = 0.001). For clarithromycin-resistant strains, vonoprazan/amoxicillin dual therapy showed superiority to vonoprazan-based triple therapy (86.7% vs. 71.4%, RR = 1.20, 95% CI: 1.03-1.39, p = 0.02); however, vonoprazan/amoxicillin dual therapy was significant inferior to vonoprazan-based triple therapy for clarithromycin-sensitive strains (83.0% vs. 92.8%, RR = 0.90, 95% CI: 0.85-0.95, p = 0.0002). The adverse effects of vonoprazan/amoxicillin dual therapy were lower than those of triple therapy (21.2% vs. 26.5%, RR = 0.86, 95% CI: 0.73-1.01, p = 0.06), especially the incidence of diarrhea (p = 0.01). CONCLUSIONS The efficacy of vonoprazan/amoxicillin dual therapy is noninferior to vonoprazan-based triple therapy but superior to the omeprazole or lansoprazole-based triple therapy and has less side effects. Patients with clarithromycin-resistant strains are particularly expected to benefit from vonoprazan/amoxicillin dual therapy.

Macedo Silva V, Lima Capela T, Freitas M, Boal Carvalho P, Magalhães J, Cotter J. A "new" option in Helicobacter pylori eradication: High-dose amoxicillin dual therapy outperforms bismuth quadruple therapy in a high dual resistance setting. Helicobacter 2023; 28:e12962. [PMID: 36828647 DOI: 10.1111/hel.12962] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2023] [Revised: 02/12/2023] [Accepted: 02/15/2023] [Indexed: 02/26/2023]
Abstract
BACKGROUND Currently, bismuth quadruple therapy (BQT) is indicated as a first-line treatment for Helicobacter pylori eradication in areas with high dual metronidazole and clarithromycin resistance, with its use being limited by its low tolerability and significant cost. A novel regimen with high-dose amoxicillin dual therapy (HDADT) has emerged as an alternative. The aim of this study was to compare the results of these two treatments on HP eradication. MATERIALS AND METHODS Prospective randomized study including 100 consecutive patients undergoing H. pylori eradication. Each patient was randomized (in a 1:1 ratio) to one group of treatment: BQT (bismuth 140 mg + metronidazole 125 mg + tetracycline 125 mg, four times a day, for 10 days) or HDADT (amoxicillin 1000 mg alternating with amoxicillin 500 mg, four times a day, for 14 days), both associated with esomeprazole 40 mg twice a day. The primary aim was to compare treatments' efficacies. Secondary aims were to assess symptoms persistence and tolerability. RESULTS A total of 100 patients were included, 54% women, with a mean age of 55 ± 14 years. From these, five were lost to follow-up. Effective eradication proven by negative stool antigen test was significantly higher in patients randomized to HDADT when compared to BQT for both intention-to-treat (ITT) (96.2% vs. 81.4%; p = .022) and per-protocol (PP) (95.9% vs. 81%; p = .025) analysis. These differences were even more pronounced when only considering second line treatment (100% vs. 62.5%; p = .028). Side effects did not differ significantly between BQT and HDADT groups for both ITT (7.0% vs. 2.0%; p = .254) and PP (4.8% vs. 0%; p = .210) analysis. CONCLUSIONS When compared to BQT, treatment with HDADT presented higher and near 100% efficacy in eradicating H. pylori, without differences in reported side effects or compliance. This treatment represents an important alternative for populations with increasing incidences of resistance to the currently recommended antibiotic regimens.

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
BACKGROUND Helicobacter pylori ( H. pylori ) can persistently colonize on the gastric mucosa after infection and cause gastritis, atrophy, metaplasia, and even gastric cancer (GC). METHODS Therefore, the detection and eradication of H. pylori are the prerequisite. RESULTS Clinically, there are some controversial issues, such as why H. pylori infection is persistent, why it translocases along with the lesser curvature of the stomach, why there is oxyntic antralization, what the immunological characteristic of gastric chronic inflammation caused by H. pylori is, whether H. pylori infection is associated with extra-gastric diseases, whether chronic atrophic gastritis (CAG) is reversible, and what the potential problems are after H. pylori eradication. What are the possible answers? CONCLUSION In the review, we will discuss these issues from the attachment to eradication in detail.

Wang Y, Zheng L. Protocatechuic acid, the main effective monomer in Wuqi Powder, can inhibit gastric ulcers induced by acetic acid and Helicobacter pylori. Am J Transl Res 2023; 15:151-164. [PMID: 36777827 PMCID: PMC9908460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2022] [Accepted: 12/05/2022] [Indexed: 02/14/2023]
Abstract
OBJECTIVE To explore the effective ingredients of Wuqi Powder and their mechanism of action, so as to provide a theoretical basis for clinical application. METHODS Enzyme-linked immunosorbent assay was used to determine interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF-α) levels. Rapid urease test and Giemsa staining were conducted to detect Helicobacter pylori (H. pylori) in gastric tissue. CCK-8, EdU and wound healing assay were used to measure the proliferation and migration of GES-1 cells. The number of intracellular and extracellular bacteria of GES-1 cells was counted to evaluate infection and adhesion of H. pylori. RT-qPCR was conducted to evaluate the level of alpA, alpB and cagA genes of H. pylori. Bioinformatics methods were used to predict the potential targets and signaling pathways of protocatechuic acid (PCA) in GES-1 cells. Then, RT-qPCR was used to detect the expression of target genes, and Western blot was conducted to detect the interaction of the target pathways. RESULTS PCA is the effective ingredient in Wuqi Powder, which alleviated the symptoms of gastric ulcers, reduced H. pylori in gastric tissue and IL-6, TNF-α in rat serum. In addition, PCA accelerated the proliferation and migration of GES-1 cells and inhibited the infection and adhesion of H. pylori to GES-1 cells. Furthermore, PCA inhibited the TNF and Smad pathways and activated the vascular endothelial growth factor A (VEGFA) pathway of GES-1 cells. CONCLUSION PCA is the key component in treating gastric ulcers induced by acetic acid and H. pylori. It promotes gastric ulcer repair by inhibiting the Smad pathway, TNF pathway and activating the VEGFA pathway.

Abstract
Helicobacter pylori (H. pylori) infection is prevalent and has a rapidly increasing antibiotic resistance rate in Vietnam. Reinfection is quite common, and gastric carcinoma remains one of the most common malignancies, which is not uncommon to develop after successful eradication. The purpose of this consensus is to provide updated recommendations on the management of H. pylori infection in the country. The consensus panel consisted of 32 experts from 14 major universities and institutions in Vietnam who were invited to review the evidence and develop the statements using the Delphi method. The process followed the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The consensus level was defined as ≥80% for agreement on the proposed statements. Due to the limited availability of high-quality local evidence, this consensus was also based on high-quality evidence from international studies, especially those conducted in other populations in the Asia-Pacific region. The panel finally reached a consensus on 27 statements after two voting rounds, which consisted of four sections (1) indications for testing and selection of diagnostic tests (2), treatment regimens, (3) post-treatment confirmation of H. pylori status, and (4) reinfection prevention methods and follow-up after eradication. Important issues that require further evidence include studies on third-line regimens, strategies to prevent H. pylori reinfection, and post-eradication follow-up for precancerous gastric lesions. We hope this consensus will help guide the current clinical practice in Vietnam and promote multicenter studies in the country and international collaborations.

Abstract
ABSTRACT Bismuth-containing quadruple therapy (BQT) has long been recommended for Helicobacter pylori ( H. pylori ) eradication in China. Meanwhile, in the latest national consensus in China, dual therapy (DT) comprising an acid suppressor and amoxicillin has also been recommended. In recent years, the eradication rate of H. pylori has reached >90% using DT, which has been used not only as a first-line treatment but also as a rescue treatment. Compared with BQT, DT has great potential for H. pylori eradication; however, it has some limitations. This review summarizes the development of DT and its application in H. pylori eradication. The H. pylori eradication rates of DT were comparable to or even higher than those of BQT or standard triple therapy, especially in the first-line treatment. The incidence of adverse events associated with DT was lower than that with other therapies. Furthermore, there were no significant differences in the effects of dual and quadruple therapies on gastrointestinal microecology. In the short term, H. pylori eradication causes certain fluctuations in the gastrointestinal microbiota; however, in the long term, the gastrointestinal microbiota eventually returns to its normal state. In the penicillin-naïve population, patients receiving DT have a high eradiation rate, better compliance, lower incidence of adverse reactions, and lower primary and secondary resistance to amoxicillin. These findings suggest the safety, efficacy, and potential of DT for H. pylori eradication.

Therap Adv Gastroenterol 2022; 15:17562848221142925. [PMID: 36600686 PMCID: PMC9806404 DOI: 10.1177/17562848221142925] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 10/25/2022] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND A high-dose proton pump inhibitor (PPI)-amoxicillin dual therapy has been investigated for treatment of patients with Helicobacter pylori (H. pylori) infection. Currently, the efficacy of this dual therapy remains inconclusive, with controversial findings from various single-center clinical trials. OBJECTIVES To assess the efficacy and safety of high-dose dual therapy (HDDT) compared with the bismuth-containing quadruple therapy (BQT) in treatment-naive patients with H. pylori infection. DESIGN A multicenter, open-label, randomized controlled clinical trial. METHODS Three hundred and forty treatment-naïve patients with H. pylori infection were prospectively recruited from seven participating hospitals. The enrolled patients were randomized into one of two treatment groups: the HDDT group (esomeprazole, 20 mg four times daily; amoxicillin, 750 mg four times daily) and the BQT group (esomeprazole, 20 mg, twice daily; bismuth potassium citrate, 600 mg, twice daily; amoxicillin, 1 g, twice daily; metronidazole, 400 mg, four times daily). The primary outcome was eradication rate, and secondary outcomes were safety and patient compliance. RESULTS The eradication rates in the HDDT group versus the BQT group were 86.47% versus 87.06% on intention-to-treat (ITT) analysis, 91.88% versus 92.50% on modified ITT (MITT) analysis, and 91.77% versus 93.04% on per-protocol (PP) analysis, with no significant differences between the two groups. The patient compliance rates in the HDDT group versus the BQT group were 97.02% versus 95.86%, and no significant difference was found between the two groups. Notably, the HDDT group exhibited significantly lower incidence in the drug-induced adverse events (AEs) compared to the BQT group (16.67% versus 47.94%). CONCLUSION HDDT is equally efficacious in eradicating H. pylori infection and resulted in good patient compliance and safety compared with BQT. These findings provide evidence in support of HDDT as a first-line treatment for H. pylori infection. REGISTRATION This clinical trial was registered at The Chinese Clinical Trial Registry (trial registration number: ChiCTR2000039096).

Abstract
Background Although the Maastricht VI/Florence consensus report recommended high-dose proton pump inhibitor-amoxicillin dual therapy as possible rescue therapy for Helicobacter pylori infection, clinical evidence of its efficacy was lacking. Objectives To compare the efficacy, safety, patient compliance, and cost between high-dose dual therapy (HDDT) and culture-based susceptibility-guided therapy (CB-SGT) as a rescue regimen for H. pylori infection. Design A single-center, open-label, randomized controlled clinical trial. Methods In all, 146 patients with a history of eradication failure were enrolled and randomly assigned to receive HDDT or CB-SGT. HDDT consisted of esomeprazole 20 mg and amoxicillin 750 mg, both given four times per day (qid). CB-SGT consisted of esomeprazole 20 mg twice daily (bid), amoxicillin 1000 mg bid plus clarithromycin 500 mg bid, metronidazole 400 mg bid, or levofloxacin 500 mg daily (qd) for sensitive patients, in that order. For patients with triple resistance, a bismuth-containing regimen with a high dose of metronidazole was chosen, including esomeprazole 20 mg bid, bismuth 220 mg bid, amoxicillin 1000 mg bid, and metronidazole 400 mg qid. All regimens were given for 14 days. Results The eradication H. pylori rates achieved with HDDT in the intention-to-treat (ITT), per-protocol, and modified ITT analyses were all 84.9% [62/73, 95% confidence interval (CI): 76.5-93.9%], compared with 83.6% (61/73, 95% CI: 74.9-92.3%), 84.7% (61/72, 95% CI: 76.2-93.2%), and 84.7% (61/72, 95% CI: 76.2-93.2%) with CB-SGT, respectively. For patients with CYP2C19 polymorphisms of intermediate/poor metabolizers, the eradication rates of HDDT and CB-SGT were 90.70% (39/43, 95% CI: 77.86-97.41%) and 84.21% (32/38, 95% CI: 68.75-93.98%), respectively. The difference between groups was 6.49% (95% CI: -8.00% to 20.97%), and the non-inferiority p value was 0.0128. For patients with a treatment interval of more than 3 months, the eradication rates of the two regimens reached 88.71% (95% CI: 78.11-95.34%) and 71.97% (95% CI: 70.02-90.64%). The difference between groups was 6.74% (95% CI: -5.71% to 19.20%), with a non-inferiority p value of 0.0042. Patient adherence was high in both groups. The HDDT had a lower cost and rate of side effects (p < 0.001) compared with CB-SGT. Conclusions HDDT can reach an eradication rate of 85% in treatment-experienced patients of H. pylori infection and 91% in patients with CYP2C19 polymorphisms of intermediate/poor metabolizers, with good compliance, lower side effects and costs, and less use of antibiotics. In conclusion, HDDT offers an effective rescue regimen for H. pylori infection.

World J Clin Cases 2022; 10:12959-12970. [PMID: 36569016 PMCID: PMC9782940 DOI: 10.12998/wjcc.v10.i35.12959] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/16/2022] [Revised: 10/08/2022] [Accepted: 11/30/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND As a first-line treatment regimen for Helicobacter pylori (H. pylori) infection, antibiotic therapy is widely used worldwide. However, the question of increasing antibiotic resistance must be considered. Given this issue, we need to find ways to reduce drug resistance. This study examined all currently available first-line regimens and compared them with standard triple treatment through a network meta-analysis of randomized controlled trials (RCTs).
AIM To compare first-line treatment regimens for eradication of antibiotic-resistant H. pylori strains.
METHODS To compare the effectiveness of the first-line regimens for treating H. pylori infection, a Bayesian network meta-analysis was applied to process data extracted from RCTs. The plausible ranking for each regimen was assessed by the surface under the cumulative ranking curve (SUCRA). In addition, we conducted a relevant search by reference citation analysis.
RESULTS Twenty-five RCTs involving 12029 participants [including 1602 infected with clarithromycin (CAM)-resistant strains and 1716 infected with metronidazole (MNZ)-resistant strains] were included, in which a total of seven regimens were used for H. pylori eradication. The results showed that dual therapy containing a high-dose proton pump inhibitor (HDDT) [odds ratio (OR): 4.20, 95% confidence interval (CI): 2.29-8.13] was superior to other therapies for all patients, including those with CAM/MNZ-resistant H. pylori infection. In the comparative effectiveness ranking, for CAM-resistant H. pylori, HDDT (OR: 96.80, 95%CI: 22.46-521.9) had the best results, whereas standard triple therapy ranked last (SUCRA: 98.7% vs 0.3%). In the subgroup of high cure rates (≥ 90%), HDDT was also generally better than other therapies.
CONCLUSION For the eradication of CAM- and MNZ-resistant H. pylori strains, HDDT exhibited considerable advantages. The studies of CAM-resistant H. pylori were based on small samples due to a lack of antibiotic sensitivity tests in many RCTs, but the results showed that all patients, including those with CAM-resistant H. pylori infection, had a concordant trend. Overall, HDDT may be a reference for RCTs and other studies of H. pylori eradication.

Abstract
Background To date, no interventional trial has assessed the efficacy and safety of vonoprazan and high-dose (500 mg four times daily, 2000 mg/day) amoxicillin dual therapy in terms of Helicobacter pylori eradication. We explored whether this was an appropriate first-line treatment. Methods This prospective, dual-center, single-arm interventional study was performed in Japan. Twenty H. pylori-positive patients lacking any eradication history were treated with vonoprazan 20 mg twice daily and amoxicillin 500 mg four times daily (qid) for 7 days. Eradication was evaluated using a stool H. pylori antigen test. We evaluated safety using patient questionnaires. This study was registered in the jRCT database (jRCT031200128). Results The intention-to-treat and per-protocol eradication rates were 90% (95% confidence interval [CI] 68.3-98.8%, n = 20) and 94.4% (95% CI 72.7-99.9%, n = 18) respectively. No significant adverse event was recorded. Conclusion Vonoprazan/high-dose amoxicillin dual therapy can be a safe standard first-line therapy. We are now undergoing a randomized controlled trial comparing dual therapy and vonoprazan-based triple therapy.

Abstract
BACKGROUND The efficacy and safety of high-dose amoxicillin (AMX) and proton pump inhibitors (PPI) dual therapy raises much more attention in recent years. Comparative studies among the dual therapies are required to explore more suitable regimens. This study compared the efficacy, adverse events, and patient compliance of three different high-dose dual regimens in treatment-naive patients of Helicobacter pylori (H. pylori) infection. MATERIALS AND METHODS The study was a prospective, multicenter, open-label, randomized controlled trial, including H. pylori-infected treatment-naive patients at 12 tertiary hospitals in China. The eligible subjects received high-dose AMX and esomeprazole (ESO) dual therapy of different regimens. They were randomly assigned to group A (ESO 20 mg plus AMX 750 mg, Qid for 14 days), group B (ESO 40 mg Bid plus AMX 1 g Tid for 14 days), or group C (ESO 20 mg plus AMX 1 g, Tid for 14 days). The eradication rates, adverse events, and patient compliance of the three groups were compared. RESULTS Between April 2021 and January 2022, a total of 1080 subjects were screened and 945 were randomized. The eradication rates in groups A, B, and C were 88.6% (95% CI 84.5%-91.9%), 84.4% (95% CI 80.0%-88.3%), and 86.7% (95% CI 82.4%-90.2%; p = .315), respectively, based on intention-to-treat analysis; 90.3% (95% CI 86.4%-93.3%), 85.5% (95% CI 81.1%-89.2%), and 87.8% (95% CI 83.6%-91.2%; p = .197), respectively, according to modified intention-to-treat analysis; and 90.4% (95% CI 86.5%-93.5%), 85.8% (95% CI 81.4%-89.5%), and 88.3% (95% CI 84.1%-91.7%; p = .202) in per-protocol analysis. History of antibiotics use in 2 years reduced eradication effect in group B (ESO 40 mg Bid, AMX 1 g Tid). The modified intention-to-treat eradication rates were 81.4% vs 90.0% among those with or without a history of antibiotics use in group B (p = .031). The adverse event rates were 13.7%, 12.7%, and 12.1% in groups A, B, and C, respectively (p = .834). Patient compliance of the three groups was similar. CONCLUSIONS Two optimized AMX and PPI dual regimens (ESO 40 mg Bid or 20 mg Tid plus AMX 1 g Tid for 14 days) had similar efficacy, safety and compliance as compared with classical dual regimen (ESO 20 mg plus AMX 750 mg Qid for 14 days) in H. pylori-infected treatment-naive patients.

Abstract
Helicobacter pyloriInfection is formally recognised as an infectious disease, an entity that is now included in the International Classification of Diseases 11th Revision. This in principle leads to the recommendation that all infected patients should receive treatment. In the context of the wide clinical spectrum associated with Helicobacter pylori gastritis, specific issues persist and require regular updates for optimised management.The identification of distinct clinical scenarios, proper testing and adoption of effective strategies for prevention of gastric cancer and other complications are addressed. H. pylori treatment is challenged by the continuously rising antibiotic resistance and demands for susceptibility testing with consideration of novel molecular technologies and careful selection of first line and rescue therapies. The role of H. pylori and antibiotic therapies and their impact on the gut microbiota are also considered.Progress made in the management of H. pylori infection is covered in the present sixth edition of the Maastricht/Florence 2021 Consensus Report, key aspects related to the clinical role of H. pylori infection were re-evaluated and updated. Forty-one experts from 29 countries representing a global community, examined the new data related to H. pylori infection in five working groups: (1) indications/associations, (2) diagnosis, (3) treatment, (4) prevention/gastric cancer and (5) H. pylori and the gut microbiota. The results of the individual working groups were presented for a final consensus voting that included all participants. Recommendations are provided on the basis of the best available evidence and relevance to the management of H. pylori infection in various clinical fields.

Abstract
BACKGROUND High-dose dual therapy (HDDT) with proton pump inhibitors (PPIs) and amoxicillin has attracted widespread attention due to its favorable efficacy in eradicating Helicobacter pylori (H. pylori). This study aimed to compare the efficacy and safety of high-dose PPI-amoxicillin dual therapy and bismuth-containing quadruple therapy for H. pylori rescue treatment. METHODS This was a prospective, randomized, multicenter, non-inferiority trial. Patients recruited from eight centers who had failed previous treatment were randomly (1:1) allocated to two eradication groups: HDDT (esomeprazole 40 mg and amoxicillin 1000 mg three times daily; the HDDT group) and bismuth-containing quadruple therapy (esomeprazole 40 mg, bismuth potassium citrate 220 mg, and furazolidone 100 mg twice daily, combined with tetracycline 500 mg three times daily; the tetracycline, furazolidone, esomeprazole, and bismuth [TFEB] group) for 14 days. The primary endpoint was the H. pylori eradication rate. The secondary endpoints were adverse effects, symptom improvement rates, and patient compliance. RESULTS A total of 658 patients who met the criteria were enrolled in this study. The HDDT group achieved eradication rates of 75.4% (248/329), 81.0% (248/306), and 81.3% (248/305) asdetermined by the intention-to-treat (ITT), modified intention-to-treat (MITT), and per-protocol (PP) analyses, respectively. The eradication rates were similar to those in the TFEB group: 78.1% (257/329), 84.2% (257/305), and 85.1% (257/302). The lower 95% confidence interval boundary (-9.19% in the ITT analysis, - 9.21% in the MITT analysis, and -9.73% in the PP analysis) was greater than the predefined non-inferiority margin of -10%, establishing a non-inferiority of the HDDT group vs. the TFEB group. The incidence of adverse events in the HDDT group was significantly lower than that in the TFEB group (11.1% vs. 26.8%, P < 0.001). Symptom improvement rates and patients' compliance were similar between the two groups. CONCLUSIONS Fourteen-day HDDT is non-inferior to bismuth-containing quadruple therapy, with fewer adverse effects and good treatment compliance, suggesting HDDT as an alternative for H. pylori rescue treatment in the local region.

Abstract
BACKGROUND The clarithromycin-based triple therapy is the most prescribed Helicobacter pylori eradication regimen in Europe; it causes adverse effects in a significant proportion of subjects, leading to discontinuation. Alternative therapies are required because of increasing clarithromycin resistance or to decrease the adverse effects. AIMS We compared the efficacy and spectrum of adverse effects of clarithromycin-based triple therapy with the high-dose amoxicillin/bismuth regimen. METHODS A randomised clinical trial enrolled healthy individuals aged 40-64 years. H. pylori was assessed with a 13C-urea breath test. In total 579 H. pylori-positive subjects were randomly allocated in two groups: group 1: clarithromycin 500 mg, amoxicillin 1000 mg, esomeprazole 40 mg, all twice daily; group 2: bismuth subcitrate 240 mg twice daily, amoxicillin 1000 mg three times daily, esomeprazole 40 mg twice daily. Regimens were administered for 14 days.Information on treatment completion and adverse effects were collected via a telephone interview at 21-28 days after medication delivery. The efficacy was assessed by UBT 6 months after the treatment. RESULTS We analysed 483 subjects for adverse effects (248 vs. 235 respectively). Furthermore, 316 subjects were analysed for efficacy. In per-protocol analysis, a higher efficacy was seen in group 1 (88.4 vs. 77.0%; P < 0.001); no difference was observed in compliance (90.3 and 91.2%). Therapy-related adverse effects were more common in group 1 (56.9 vs. 40.0%; P < 0.01). In intention-to-treat analysis no statistical difference in efficacy was revealed. CONCLUSIONS Bismuth-based high-dose amoxicillin therapy showed a lower efficacy but was less frequently associated with adverse effects. Further research is required to examine the high-dose amoxicillin and bismuth-containing regimens in various populations to maximise eradication efficacy.

Effectiveness and Safety of High-Dose Dual Therapy: Results of the European Registry on the Management of Helicobacterpylori Infection (Hp-EuReg). J Clin Med 2022; 11:jcm11123544. [PMID: 35743627 PMCID: PMC9225562 DOI: 10.3390/jcm11123544] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Revised: 06/15/2022] [Accepted: 06/15/2022] [Indexed: 02/01/2023] Open
Abstract
Background: Randomized clinical trials and meta-analyses, primarily from Asian countries, have reported good effectiveness with high-dose dual therapy (HDDT) including a proton pump inhibitor (PPI) and amoxicillin when prescribed as H. pylori first-line or rescue treatment. However, combining amoxicillin with PPIs in the 1990s in several European countries yielded suboptimal results. Methods: An international, multicenter, prospective non-interventional Registry (Hp-EuReg) aimed to evaluate the decisions and outcomes of H. pylori management by European gastroenterologists. All infected adult cases treated with HDDT were registered at e-CRF AEG-REDCap platform until June 2021. Sixty patients were prescribed with HDDT (98% compliance), 19 of them received a first-line therapy and 41 a rescue treatment (second- to sixth-line). Results: Overall HDDT effectiveness was 52% (per-protocol) and 51% (modified intention-to-treat). First-line and rescue treatment lines were equally effective, but the effectiveness was worse when patients had previously received metronidazole, tetracycline, or rifabutin. Adding bismuth to HDDT in rescue treatment did not yield better results. The incidence of adverse events was 30%, diarrhea being the most common (20% of patients); no serious adverse events were reported. Conclusion: Although HDDT is safe and has good compliance, it is not a good option in European first-line or rescue H. pylori treatment, even when adding bismuth.

Abstract
Helicobacter pylori infects nearly one-third of the US population. H pylori is a significant cause of gastroduodenal disease, including peptic ulcers and cancers. However, rising antibiotic resistance has complicated management of H pylori. This article provides a practical review of management strategies, including first-line empiric therapies and how to treat patients when prior therapies fail. Bismuthbased quadruple therapy remains the standard initial empiric regimen, although a rifabutin-based triple regimen is another approach for empiric therapy in the United States. Clarithromycin and levofloxacin therapies should be avoided except when treating a strain of known susceptibility. When therapies fail, resistance should be tested with molecular or culture-based methods. Knowing local resistance patterns and/or using practice-based eradication rates is important for devising logic-based clinical choices. Ultimately, shared decision-making, patient counseling, and careful attention to drug type and dosage are essential for refractory cases.

Abstract
Helicobacter pylori infection is very common in the Spanish population and represents the main cause of chronic gastritis, peptic ulcer, and gastric cancer. The last iteration of Spanish consensus guidelines on H. pylori infection was conducted in 2016. Recent changes in therapeutic schemes along with increasing supporting evidence were key for developing the V Spanish Consensus Conference (May 2021). Fourteen experts performed a systematic review of the scientific evidence and developed a series of recommendations that were subjected to an anonymous Delphi process of iterative voting. Scientific evidence and the strength of the recommendation were classified using GRADE guidelines. An eradication therapy, when prescribed empirically, is considered acceptable when it reliably achieves, or preferably surpass, 90% cure rates. Currently, only quadruple therapies (with or without bismuth) and generally lasting 14 days, accomplish this goal in first- and second-line therapies. A non-bismuth quadruple concomitant regimen (proton pump inhibitor, clarithromycin, amoxicillin, and metronidazole) or a quadruple bismuth-based combination (proton pump inhibitor, bismuth, tetracycline, and metronidazole), are recommended as first-line regimens. Rescue therapies after eradication failure and management of H. pylori infection in peptic ulcer disease were also reviewed.

Rabeprazole plus amoxicillin dual therapy is equally effective to bismuth-containing quadruple therapy for Helicobacter pylori eradication in central China: A single-center, prospective, open-label, randomized-controlled trial. Helicobacter 2022; 27:e12876. [PMID: 35150597 DOI: 10.1111/hel.12876] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 01/10/2022] [Accepted: 01/16/2022] [Indexed: 12/11/2022]
Abstract
BACKGROUND Antibiotic resistance emerges as a major issue for Helicobacter pylori (H. pylori) treatment. High-dose dual therapy has recently shown encouraging results in H. pylori eradication, but it has yet to be validated in this H. pylori highly infected area; it is also not known if this concept can be extended to antibiotics other than amoxicillin, and factors that affect the eradication. We investigate if rabeprazole plus amoxicillin or furazolidone regimens could be a first-line therapy for H. pylori eradication, and factors that affect the curing rate. METHODS This is a single-center, prospective, open-label, randomized-controlled trial. Naive patients (n=292) were randomly treated with bismuth-containing quadruple therapy (BQT), rabeprazole plus amoxicillin (RADT), or furazolidone (RFDT) groups. RADT and FADT use three times daily regimens. H. pylori diagnosis and eradication were determined and confirmed by 13 C-urea breath test. RESULTS In per-protocol (PP) analysis, H. pylori eradication rate was 91.2% in BQT group, 89.6% in RADT, and 51.0% in RFDT group. In intention-to-treat (ITT) analysis, infection was eradicated in 86.7% of patients in BQT group, 85.8% in RADT, and 48.1% in RFDT groups, respectively. Noninferiority was confirmed between BQT and RADT groups. The incidence of side effects in BQT group was significantly higher than that in RADT group. Successful eradication was associated with lower body surface area (BSA) and low body mass index (BMI) in BQT group. Smoking and high BSA index reduced H. pylori eradication rate in RADT group. CONCLUSIONS Rabeprazole-amoxicillin dual therapy is equally effective to the bismuth-containing quadruple therapy for H. pylori eradication with fewer side effects and saves use of one antibiotic per each treatment. Successful eradication is also associated with low BSA and non-smoking condition, which deserves future stratified analysis for refinement and optimization.

[PMID: 35339174 DOI: 10.2174/1389557522666220325153832] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 01/04/2022] [Accepted: 01/12/2022] [Indexed: 01/10/2023]
Abstract
Helicobacter pylori (H. pylori) is a Gram negative spiraliform bacterium who colonizes the human stomach. It is the most common cause of chronic gastritis, peptic ulcer, and gastric carcinoma. The eradication therapy is based on the combination of a proton pump inhibitor and several antibiotics such as amoxicillin, metronidazole, clarithromycin, levofloxacin or tetracycline. The most commonly used regimens for eradication in the first line are triple, sequential and concomitant therapy, despite the last European Guidelines suggesting a quadruple therapy already at the first attempt in areas with high resistance rates. However, the rise in antibiotic resistance is the main reason for a marked increase in first-line therapy failure. Clarithromycin resistancea , is especially acknowledged as the most important event resulting in failure. Up to 20% of patients are intended not to eradicate, therefore they will need a second line therapy. Currently, the most used rescue regimens are levofloxacin-based triple therapy and bismuth-containing quadruple therapy, despite guidelines suggesting to use a combination of antibiotics that have not been included in previous treatments. Nitazoxanide is a novel antibiotic with promising results. Additionally, an interesting field worth of investigation is the antibiotic susceptibility based approach, which could help to choose antibiotics with confirmed effectiveness in vitro. Analysis of antibiotic resistance may be performed by both bacterial culture and molecular biology techniques, able to detect point mutations conferring resistance. This is a particularly interesting approach, since it may personalize the therapy, thus optimizing the regimen and maximizing the probability of success.

Abstract
INTRODUCTION Helicobacter pylori infection affects approximately 70% of the Chilean population. It is a public health problem whose eradication treatment is part of the explicit health guarantees in Chile. OBJECTIVES Characterize the most widely used H. pylori first-line eradication therapies in our environment and evaluate their efficacy. METHODS A retrospective observational study was carried out where, in patients with certified H. pylori infection, the eradication therapy indicated by the treating physician, its efficacy, adherence and adverse effects, in addition to the eradication certification method used, were evaluated. RESULTS 242 patients and 4 main therapies were analyzed: standard triple therapy, dual therapy, concomitant therapy, and bismuth quadruple therapy. Eradication rates of 81.9% (95% CI 74.44-87.63), 88.5% (95% CI 73.13-95.67), 93.7% (95% CI 78.07-98.44) and 97.6% (95% CI 84.81-99.67) were observed respectively, with concomitant therapy (RR: 1.14; 95% CI 1.01-1.29; p=.028) and quadruple therapy with bismuth (RR: 1.19; 95% CI 1.09-1.31; p<.001) being significantly more effective than standard triple therapy. Regarding the rate of reported adverse effects, it was 58.5% (95% CI 50.66-65.92), 35.4% (95% CI 24.6-48.11), 22.9% (95% CI 81-37.14) and 63.4% (95% CI 47.8-76.64), having the dual and concomitant therapy significantly fewer adverse effects compared with standard therapy. CONCLUSIONS Quadruple therapies are superior to standard triple therapy and should be considered as first-line treatment in Chile. Dual therapy is promising. More studies will be required to determine which therapies are most cost-effective.

Helicobacter 2021; 26:e12833. [PMID: 34318966 DOI: 10.1111/hel.12833] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2021] [Revised: 06/16/2021] [Accepted: 06/21/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Inconsistent eradication rates for Helicobacter pylori have been reported worldwide with dual therapy, perhaps owing to the difference in dose administration and treatment duration. This retrospective study aimed to determine whether high-dose dual therapy (HDDT) with different regimens leads to different eradication rates. The study compares the efficacy and safety of HDDT 10-day vs 14-day and investigates the factors that might affect the eradication rates. MATERIALS AND METHODS Two comparable treatment groups were based on propensity score matching (PSM). Patients were divided into two groups based on the therapy they underwent: 10-day HDDT and 14-day HDDT (20 mg esomeprazole and 750 mg amoxicillin, administered four times daily). The eradication rates, adverse events (AEs), patient compliance, CYP2C19 gene polymorphisms, and antibiotic resistance rates of the two groups were compared. RESULTS The intention to treat (ITT) analysis showed that the eradication rates for 10-day and 14-day groups were 78.4% (95% CI 69.6%-87.2%) and 89.7% (95% CI 83.3%-96.2%; p = .039), respectively, while the per-protocol (PP) eradication rates were 80.0% (95% CI 71.3%-88.7%) and 92.9% (95% CI 87.4%-98.5%; p = .014), respectively. The corresponding drug-related AEs were 6.8% (6/88) and 5.7% (5/88; p = .755). No significant differences were observed between the compliance rates of the two groups. The CYP2C19 gene polymorphism had no effect on the eradication rates of the two groups. CONCLUSION The results showed that the 14-day HDDT affords a higher H. pylori eradication rate than the 10-day HDDT.

Antibiotics (Basel) 2021; 10:antibiotics10091028. [PMID: 34572610 PMCID: PMC8467492 DOI: 10.3390/antibiotics10091028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/12/2021] [Accepted: 08/18/2021] [Indexed: 12/21/2022] Open
Abstract
Helicobacter pylori infection may persist after multiple eradication treatments. The aim of this study was to evaluate the efficacy and safety of a furazolidone-based rescue regimen in hyper-refractory patients. A unicentre, prospective study was designed. Patients in whom five or more treatments had consecutively failed were included. All patients had previously received bismuth and key antibiotics, such as amoxicillin, clarithromycin, metronidazole, levofloxacin, tetracycline, and rifabutin, and had positive H. pylori culture, demonstrating resistance to clarithromycin, metronidazole, and levofloxacin. A quadruple regimen with furazolidone (200 mg), amoxicillin (1 g), bismuth (240 mg), and esomeprazole (40 mg) was prescribed twice a day for 14 days. Eradication was confirmed by the stool antigen test. Compliance was determined through questioning, and adverse effects using a questionnaire. Eight patients (mean age 56 years, 63% men, 38% peptic ulcer disease, 12% gastric cancer precursor lesions, and 50% functional dyspepsia) were included. Per-protocol and intention-to-treat eradication rates were 63%. Compliance was 100%. Adverse effects were reported in two (25%) patients, and all were mild. Even after five or more previous H. pylori eradication failures, and a multi-resistant infection, rescue treatment with furazolidone may be effective in approximately two-thirds of the cases, constituting a valid strategy after multiple previous eradication failures with key antibiotics such as clarithromycin, metronidazole, tetracycline, levofloxacin, and rifabutin.

Abstract
BACKGROUND Antibiotic resistance is the main cause of Helicobacter pylori (H. pylori) treatment failure. This study aimed to explore the characteristics of antibiotic resistance of H. pylori isolates in Beijing in the last 8 years and to estimate the impact of previous eradication failure on resistance patterns. MATERIALS AND METHODS This retrospective study included data from a single center in Beijing from 2013 to 2020. Antibiotic susceptibility of 365 clinical H. pylori isolates was tested for amoxicillin, clarithromycin, metronidazole, levofloxacin, moxifloxacin, and tetracycline. The characteristics of the included patients and their previous eradication history were collected. Primary and secondary resistance rates of H. pylori to the six antibiotics and the impact of previous eradication failure on antibiotic resistance patterns were analyzed. RESULTS The overall primary resistance rates of amoxicillin, clarithromycin, metronidazole, levofloxacin, moxifloxacin, and tetracycline were 0.7%, 55.2%, 68.0%, 49.7%, 64.5%, and 0%, with no significant increase during the observed period; while the secondary resistance rates were 3.2%, 96.7%, 90.7%, 93.1%, 80.0%, and 0%, respectively. The secondary resistance rate of clarithromycin (p < .001), metronidazole (p = .001), and levofloxacin (p < .001) significantly increased to 100% as the number of previous eradication therapies increased and exhibited a linear association. For strains naive to eradication, only 6.8% were susceptible to all the antibiotics, while 32.4% were single resistant, and 60.8% dual or multiple resistant. Clarithromycin+metronidazole+fluoroquinolone multiple resistance was the predominant pattern (0 course: 21.6%, 1 course: 37.5%, 2 courses: 56.1%, ≥3 courses: 71.1%; p < .001) for patients with treatment failure. The prevalence of dual or multiple-resistance patterns increased significantly as the number of previous therapies increased. CONCLUSIONS The prevalence of primary and secondary resistance rates of clarithromycin, metronidazole, moxifloxacin, and levofloxacin were high in Beijing. Multiple-resistance patterns were common after treatment failure. Resistance rates of amoxicillin and tetracycline remained low and stable.

PPI-amoxicillin dual therapy four times daily is superior to guidelines recommended regimens in the Helicobacter pylori eradication therapy within Asia: A systematic review and meta-analysis. Helicobacter 2021; 26:e12816. [PMID: 34002433 DOI: 10.1111/hel.12816] [Citation(s) in RCA: 25] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2021] [Revised: 04/17/2021] [Accepted: 04/19/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Systematic reviews suggested that the eradication efficacy of PPI-amoxicillin dual therapy is similar to that of other commonly used regimens. However, it might be affected by the medication frequency. Basic and clinical studies have shown that dual therapy administered four-times daily has a reliable pathophysiological basis and could achieve satisfactory efficacy. Therefore, a systematic review of RCTs of dual therapy and other regimens was conducted to clarify whether dual therapy is superior to guidelines recommended regimens. MATERIALS AND METHODS The RCTs comparing dual therapy with other regimens were subjected to meta-analysis to evaluate the eradication rate, adverse reactions, and compliance using a random-effects model. RESULTS Dual therapy administered four-times daily had a higher eradication rate than other regimens (intention-to-treat analysis: 89.7% vs 84.6%, OR: 1.52, 95%CI 1.08-2.14, p = 0.02; per-protocol analysis: 92.6% vs 88.2%, OR: 1.54, 95%CI 1.01-2.34, p = 0.04). In first-line therapy, according to intention-to-treat analysis, the eradication rate of dual therapy was higher than other regimens (89.8% vs 84.2%, OR: 1.63, 95%CI 1.02-2.61, p = 0.04). In per-protocol analysis, dual therapy showed better efficacy than others (92.9% vs 88.3%, OR: 1.68, 95% CI 0.98-2.89, p = 0.06), but not significantly. In salvage treatment, no significant difference was detected. The safety of dual therapy was significantly better than other regimens (19.6% vs 36.7%, p < 0.01), but no difference was observed in compliance (p = 0.58). CONCLUSION PPI-amoxicillin dual therapy administered four-times daily has better efficacy and safety in H. pylori eradication than current guidelines recommended regimens, especially in first-line therapy, and mainly in Asia.

Abstract
Background/Aims: Curing Helicobacter pylori infection remains challenging for clinicians, as no proposed first-line therapy achieves bacterial eradication in all treated patients so that several patients need two or more consecutive treatments. Bacterial culture with antibiotics susceptibility testing is largely unachievable in Italy, and empiric second-line and rescue therapies are generally used. This study aimed to identify what eradication regimens perform better in Italy, following first-line therapy failure. Methods: We performed a literature search on PubMed for studies on standard therapy regimens used as second-line or rescue treatments performed in adult patients. Studies including modified drug combinations were not considered. Both intention-to-treat and per- protocol analyses were computed for each therapy subgroup. Results: Data from 35 studies with a total of 4830 patients were eventually considered. As a second-line therapy, Pylera® (90.6%) and a sequential regimen (89.8%) achieved eradication rates significantly higher than other therapies. For third-line therapy, a levofloxacin-based regimen and Pylera® achieved comparable eradication rates (88.2% vs. 84.7%; p = 0.2). Among therapies used as fourth (or more) attempts, Pylera® and a rifabutin-based therapy achieved 77.4% and 66.4% cure rates, respectively (p = 0.013). A therapy sequence based on the type of first-line therapy used was proposed. Conclusions: Data obtained through our review indicate that standard therapies for H. pylori eradication can be used when following an appropriate sequence, allowing clinicians to improve the cure rate without resorting to bacterial culture.
