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.

Patel A, Laine L, Moayyedi P, Wu J. AGA Clinical Practice Update on Integrating Potassium-Competitive Acid Blockers Into Clinical Practice: Expert Review. Gastroenterology 2024:S0016-5085(24)05226-0. [PMID: 39269391 DOI: 10.1053/j.gastro.2024.06.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2024] [Revised: 06/08/2024] [Accepted: 06/24/2024] [Indexed: 09/15/2024]
Abstract
DESCRIPTION The purpose of this American Gastroenterological Association (AGA) Institute Clinical Practice Update (CPU) is to summarize the available evidence and offer expert Best Practice Advice on the integration of potassium-competitive acid blockers (P-CABs) in the clinical management of foregut disorders, specifically including gastroesophageal reflux disease, Helicobacter pylori infection, and peptic ulcer disease. METHODS This expert review was commissioned and approved by the AGA Institute Governing Board and CPU Committee to provide timely guidance on a topic of high clinical importance to the AGA membership. This CPU expert review underwent internal peer review by the CPU Committee and external peer review through the standard procedures of Gastroenterology. These Best Practice Advice statements were developed based on review of the published literature and expert consensus opinion. Because formal systematic reviews were not performed, these Best Practice Advice statements do not carry formal ratings of the quality of evidence or strength of the presented considerations. Best Practice Advice Statements BEST PRACTICE ADVICE 1: Based on nonclinical factors (including cost, greater obstacles to obtaining medication, and fewer long-term safety data), clinicians should generally not use P-CABs as initial therapy for acid-related conditions in which clinical superiority has not been shown. BEST PRACTICE ADVICE 2: Based on current costs in the United States, even modest clinical superiority of P-CABs over double-dose proton pump inhibitors (PPIs) may not make P-CABs cost-effective as first-line therapy. BEST PRACTICE ADVICE 3: Clinicians should generally not use P-CABs as first-line therapy for patients with uninvestigated heartburn symptoms or nonerosive reflux disease. Clinicians may use P-CABs in selected patients with documented acid-related reflux who fail therapy with twice-daily PPIs. BEST PRACTICE ADVICE 4: Although there is currently insufficient evidence for clinicians to use P-CABs as first-line on-demand therapy for patients with heartburn symptoms who have previously responded to antisecretory therapy, their rapid onset of acid inhibition raises the possibility of their utility in this population. BEST PRACTICE ADVICE 5: Clinicians should generally not use P-CABs as first-line therapy in patients with milder erosive esophagitis (EE) (Los Angeles classification of erosive esophagitis grade A/B EE). Clinicians may use P-CABs in selected patients with documented acid-related reflux who fail therapy with twice-daily PPIs. BEST PRACTICE ADVICE 6: Clinicians may use P-CABs as a therapeutic option for the healing and maintenance of healing in patients with more severe EE (Los Angeles classification of erosive esophagitis grade C/D EE). However, given the markedly higher costs of the P-CAB presently available in the United States and the lack of randomized comparisons with double-dose PPIs, it is not clear that the benefits in endoscopic outcomes over standard-dose PPIs justify the routine use of P-CABs as first-line therapy. BEST PRACTICE ADVICE 7: Clinicians should use P-CABs in place of PPIs in eradication regimens for most patients with H pylori infection. BEST PRACTICE ADVICE 8: Clinicians should generally not use P-CABs as first-line therapy in the treatment or prophylaxis of peptic ulcer disease. BEST PRACTICE ADVICE 9: Although there is currently insufficient evidence for clinicians to use P-CABs as first-line therapy in patients with bleeding gastroduodenal ulcers and high-risk stigmata, their rapid and potent acid inhibition raises the possibility of their utility in this population.

Peng C, Xu X, Ouyang Y, Li Y, Lu N, Zhu Y, He C. Spatial Variation of the Gastrointestinal Microbiota in Response to Long-Term Administration of Vonoprazan in Mice With High Risk of Gastric Cancer. Helicobacter 2024; 29:e13117. [PMID: 39086007 DOI: 10.1111/hel.13117] [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: 03/19/2024] [Revised: 05/26/2024] [Accepted: 07/17/2024] [Indexed: 08/02/2024]
Abstract
BACKGROUND Vonoprazan, a potassium-competitive acid blocker, is superior to traditional proton pump inhibitor (PPI) in acid suppression and has been approved in the treatment of acid-related disorders. Accumulating evidence suggest associations between PPI use and gut microbiota, yet the effect of vonoprazan on GI microbiota is obscure. METHODS Transgenic FVB/N insulin-gastrin (INS-GAS) mice as a model of gastric cancer (GC) were administered vonoprazan by gavage every other day for 12 weeks. Stomachs were evaluated by histopathology, Ki-67 proliferation index, and inflammatory cytokines. The mucosal and lumen microbiota from stomach, jejunum, ileum, cecum, and feces were detected using 16S rRNA gene sequencing. RESULTS Higher incidence of intestinal metaplasia and epithelial proliferation were observed in the vonoprazan group than that in the control mice. Vonoprazan also elevated the gastric expression of proinflammatory cytokines, including TNF-α, IL-1β, and IL-6. Each mice comprised a unique microbiota composition that was consistent across different niches. The structure of GI microbiota changed dramatically after vonoprazan treatment with the stomach being the most disturbed segment. Vonoprazan administration shifted the gut microbiota toward the enrichment of pathogenic Streptococcus, Staphylococcus, Bilophila, and the loss of commensal Prevotella, Bifidobacterium, and Faecalibacterium. Interestingly, compared to the controls, microbial interactions were weaker in the stomach while stronger in the jejunum of the vonoprazan group. CONCLUSIONS Long-term vonoprazan treatment promoted gastric lesions in male INS-GAS mice, with the disequilibrium of GI microbiome. The clinical application of vonoprazan needs to be judicious particularly among those with high risk of GC.

Comparison of vonoprazan dual therapy, quadruple therapy and standard quadruple therapy for Helicobacter pylori infection in Hainan: a single-center, open-label, non-inferiority, randomized controlled trial. BMC Gastroenterol 2024; 24:131. [PMID: 38609893 PMCID: PMC11010374 DOI: 10.1186/s12876-024-03225-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Accepted: 04/09/2024] [Indexed: 04/14/2024] Open
Abstract
OBJECTIVE To compare the potential efficacy and safety of dual therapy and quadruple therapy with vonoprazan (VPZ) as well as the standard quadruple therapy of proton pump inhibitor (PPI) for the eradication of Helicobacter pylori (Hp) infection in Hainan province. METHODS A single-centre, non-blinded, non-inferiority randomized controlled trial was conducted at the outpatient department of gastroenterology at the Second Affiliated Hospital of Hainan Medical University from June 2022 to February 2023. 135 patients aged 18-75 years with Hp infection were enrolled and randomized into three different groups (group V1: VPZ 20 mg twice a day and amoxicillin 1.0 g three times a day for 14 days V2: vonoprazan 20 mg, amoxicillin capsules 1.0 g, furazolidone 0.1 g and bismuth potassiulm citrate 240 mg, twice daily for 14 days;; group V3: ilaprazole 5 mg, Amoxicillin 1.0 g, Furazolidone 100 mg, bismuth potassiulm citrate 240 mg, twice a day for 14 days). Four weeks after the end of treatment, Hp eradication was confirmed by rechecking 13C-urea breath test (UBT). RESULTS The eradication efficacy of V1 and V3 was non-inferior to that of V2, which is consistent with the results obtained from the Kruskal-Wallis H test. The eradication rate by intentional analysis was 84.4% (38/45, 95%CI 73.4%-95.5%, P>0.05) for all the three groups. If analyzed by per-protocol, the eradication rates were 88.4% (38/43, 95%CI 78.4%-98.4%), 92.7% (38/41, 95%CI 84.4%-101.0%),88.4% (38/43,95%CI 78.4%-98.4%) in groups V1, V2 and V3, respectively, which did not show a significant difference (P > 0.05). The incidence of adverse effects was significantly lower in VPZ dual therapy compared to the other two treatment regimens (P < 0.05). VPZ dual therapy or quadruple therapy was also relatively less costly than standard quadruple therapy. CONCLUSION VPZ dual therapy and quadruple therapy shows promise of not being worse than the standard quadruple therapy by a clinically relevant margin. More studies might be needed to definitively determine if the new therapy is equally effective or even superior.

Abstract
Helicobacter pylori (H. pylori) is a major factor in peptic ulcer disease and gastric cancer, and its infection rate is rising globally. The efficacy of traditional antibiotic treatment is less effective, mainly due to bacterial biofilms and the formation of antibiotic resistance. In addition, H. pylori colonizes the gastrointestinal epithelium covered by mucus layers, the drug must penetrate the double barrier of mucus layer and biofilm to reach the infection site and kill H. pylori. The ethanol injection method was used to synthesize nanoliposomes (EPI/R-AgNPs@RHL/PC) with a mixed lipid layer containing rhamnolipids (RHL) and phosphatidylcholine (PC) as a carrier, loaded with the urease inhibitor epiberberine (EPI) and the antimicrobial agent rubropunctatin silver nanoparticles (R-AgNPs). EPI/R-AgNPs@RHL/PC had the appropriate size, negative charge, and acid sensitivity to penetrate mucin-rich mucus layers and achieve acid-responsive drug release. In vitro experiments demonstrated that EPI/R-AgNPs@RHL/PC exhibited good antibacterial activity, effectively inhibited urease activity, removed the mature H. pylori biofilm, and inhibited biofilm regeneration. In vivo antibacterial tests showed that EPI/R-AgNPs@RHL/PC exhibited excellent activity in eradicating H. pylori and protecting the mucosa compared to the traditional clinical triple therapy, providing a new idea for the treatment of H. pylori infection.

Abstract
Background: Vonoprazan has been reported to exert more potent and long-lasting gastric acid inhibition than proton pump inhibitors, potentially leading to a greater impact on the gut microbiota. This study aimed to clarify changes in microbial diversity and bacterial composition after VPZ treatments. Methods: We searched from PubMed, Embase, WOS, Scopus, Cochrane Library, and ClinicalTrials.gov (all years up to May 2023). The primary outcomes were alpha and beta diversity, as well as differences in gut microbiota composition between before and after VPZ treatments. We performed a meta-analysis to uncover the potential changes in human gut microbiota among VPZ users by pooled mean difference (MD) with a 95% confidence interval (CI). The risk of bias was assessed using the ROBINS-I tool. Results: A total of 12 studies were included to compare differences before and after VPZ treatments. Compared with baseline, alpha diversity was significantly reduced after VPZ treatments and gradually returned to baseline with longer follow-up. At the phylum level, there was a decrease in the relative abundance of Firmicutes and Actinobacteria, while Bacteroidetes increased compared with baseline. At the genus level, we found a significant decrease in the relative abundance of Coprococcus and Bifidobacterium and a significant increase in the relative abundance of Bacteroides compared with those before treatment. In subgroup analyses according to country and participants, we found differences in microbial changes after VPZ treatments. Conclusion: Vonoprazan can affect the changes of gut microbiota, which may be potentially associated with its strong ability of acid inhibition. However, due to the large heterogeneity, further studies are required to validate these findings. Systematic Review Registration: https://www.crd.york.ac.uk/prospero/, identifier CRD42023412265.

Pilot studies of vonoprazan-containing Helicobacter pylori eradication therapy suggest Thailand may be more similar to the US than Japan. Helicobacter 2023; 28:e13019. [PMID: 37723133 DOI: 10.1111/hel.13019] [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: 02/20/2023] [Revised: 08/01/2023] [Accepted: 08/27/2023] [Indexed: 09/20/2023]
Abstract
BACKGROUND Vonoprazan-containing Helicobacter pylori eradication is reliably effective in Japan. Its effectiveness in other countries remains unclear. Here, we examined vonoprazan-H. pylori therapies in Thailand. MATERIALS AND METHODS This was pilot study of four different vonoprazan containing therapies. Subjects were randomized to: 14-day dual therapy (500 mg amoxicillin q.i.d. plus 20 mg vonoprazan b.i.d.), 14-day triple therapy (amoxicillin 1 g b.i.d., slow release clarithromycin-MR, 1 g daily plus vonoprazan 20 mg b.i.d.), 7-day high-dose vonoprazan triple therapy (amoxicillin 1 g b.i.d., clarithromycin-MR 1 g daily and 60 mg vonoprazan once daily), and 14-day vonoprazan triple therapy plus bismuth (amoxicillin 1 g b.i.d., clarithromycin-MR 1 g daily, vonoprazan 20 mg b.i.d., and bismuth subsalicylate 1048 mg b.i.d.). Eradication was confirmed 4 weeks after therapy. Antimicrobial susceptibility and CYP3A4/5 genotyping were performed. RESULTS One hundred H. pylori-infected patients (mean age 54.3 ± 13 years, 51% men) were randomized. All were CYP3A4 extensive metabolizers. Cure rates with both 14-day vonoprazan dual therapy and 14-day triple therapy were low: 66.7%; 95% CI = 43-85% (14/21), and 59.3%; 95% CI = 39-78%) (16/27), respectively. In contrast, 7-day high-dose vonoprazan triple therapy and 14-day vonoprazan triple plus bismuth proved effective 92.3%; 95% CI = 75%-99% (24/26) and 96.2%; 95% CI = 80%-100% (25/26), respectively. CONCLUSION Both 14-day vonoprazan dual and triple therapy were ineffective for H. pylori eradication in Thailand. Higher dosage of vonoprazan, and/or the addition of bismuth may be required to achieve high H. pylori eradication rates. High-dose vonoprazan triple therapy and vonoprazan triple therapy adding bismuth might be used as first-line treatments in some regions with high efficacy irrespective of CYP3A4/5 genotype and clarithromycin resistance.

Abstract
Helicobacter pylori is a gram-negative bacterium that chronically infects the gastric epithelium. Potassium-competitive acid blockers (P-CABs) are a promising alternative, being more potent than standard proton pump inhibitors (PPIs). The meta-analysis followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria were randomized controlled trials (RCTs) comparing P-CAB and PPI-based therapy, confirmed H. pylori infection, and measured eradication rates after at least four weeks. Subgroup analyses were conducted based on therapy type and trial location. Quality assessment used the Cochrane risk-of-bias tool, RoB 2.0, and statistical analysis was performed using ReviewManager (RevMan) 5.4 (2020; The Cochrane Collaboration, London, United Kingdom). A p-value of <0.05 is considered statistically significant. In the intention-to-treat (ITT) analysis, P-CABs demonstrated superior overall efficacy, consistently observed in the first-line treatment subgroup. However, no significant difference was found in the subgroup receiving salvage therapy. Another ITT subgroup analyzed the impact of geographical location, favoring P-CABs in the overall study population and the Japanese subgroup. However, no statistically significant differences were found in the subgroups of other countries. In the PPA, P-CABs showed superior efficacy overall, consistently seen in the first-line treatment subgroup. However, no significant difference was found in the subgroup receiving salvage eradication therapy. Another PPA subgroup analysis considered the geographical impact on eradication rates, revealing P-CABs as superior to PPIs in the overall study population and the Japanese subgroup, but not in other countries. No significant adverse event outcomes were observed. P-CAB-based triple therapy is more effective than PPI-based triple therapy as the primary treatment for H. pylori eradication, particularly in Japanese patients. Nevertheless, regarding salvage therapy, both treatments show comparable efficacy. Additionally, the tolerability of P-CAB-based and PPI-based triple therapy is similar, with a similar occurrence of adverse events.

Abstract
INTRODUCTION Antibiotic resistance of Helicobacter pylori (H. pylori) hampers the success of eradication and in recent years multidrug resistance (MDR) shows an increase worldwide. AREAS COVERED This review covers current aspects of pharmacological and regulatory management of MDR-resistant H. pylori infection. EXPERT OPINION MDR H. pylori is increasing worldwide and its prevalence varies both between continents and countries. High consumption and misuse of antibiotics, H. pylori treatment failures and bacterial factors such as mutations, efflux pumps and biofilms are among the factors associated with MDR. Important steps for confronting the rise of MDR H. pylori strains should follow the principles of antibiotic stewardship, i.e. eradication regimens should be optimized with regard to all aspects of therapy, including drugs, doses, formulation, frequency of administration, administration in relation to meals and duration of therapy that reliably achieve at least 90% (preferably >95%) cure rates in adherent patients with susceptible infections.

Abstract
BACKGROUND Vonoprazan is a potassium competitive acid blocker (P-CAB) approved in Japan in 2014 to treat endoscopic submucosal dissection (ESD)-induced ulcers and bleeding or perforation. Therefore, this meta-analysis aimed to determine whether Vonoprazan is more effective than Lansoprazole in the treatment of ESD-induced ulcers which include ulcer healing and shrinking rate, among others. METHODS Randomized controlled trials (RCT) and retrospective studies were collected from the PubMed (Medline), Embase, Web of science and Cochrane Library databases. Meanwhile, studies were selected according to predetermined qualification criteria and data were extracted by two researchers. The quality of the methods for published papers was evaluated using the modified Jadad scale. RESULTS Five studies were included in this meta-analysis, the ulcer healing rate effect was not significantly higher in the intervention groups than in the control groups at 4 weeks, [OR:1.07 (0.51, 2.22), 95% CI, I2=2%, Z=0.18, P=0.86]. There was no significant difference in the ulcer shrinkage rate at 4 weeks [MD:0.20 (-1.51, 1.92), 95% CI, I2=0%, P=0.82] and 8 weeks [MD: -0.09 (-0.30, 0.12), 95% CI, I2=0%, P=0.39]. CONCLUSION There was no significant difference between Vonoprazan and Lansoprazole in the ulcers induced by treatment after 4 weeks and 8 weeks of treatment with ESD.

Abstract
Helicobacter pylori infects approximately 50% of the world's population and is considered the major etiological agent of severe gastric diseases, such as peptic ulcers and gastric carcinoma. Increasing resistance to standard antibiotics has now led to an ever-decreasing efficacy of eradication therapies and the development of novel and improved regimens for treatment is urgently required. Substantial progress has been made over the past few years in the identification of molecular mechanisms which are conducive to resistant phenotypes as well as for efficient strategies to counteract strain resistance and to avoid the use of ineffective antibiotics. These involve molecular testing methods, improved salvage therapies, and the discovery of novel and potent antimicrobial compounds. High rates of prevalence and gastric cancer are currently observed in Asian countries, including Japan, China, Korea, and Taiwan, where concomitantly intensive research efforts were initiated to explore advanced eradication regimens aimed at reducing the risk of gastric cancer. In this review, we present an overview of the known molecular mechanisms of antibiotic resistance and discuss recent intervention strategies for H. pylori diseases, with a view of the research progress in Asian countries.

Helicobacter 2023; 28:e12940. [PMID: 36458325 PMCID: PMC10078362 DOI: 10.1111/hel.12940] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 10/23/2022] [Accepted: 11/15/2022] [Indexed: 12/09/2022]
Abstract
BACKGROUND Although vonoprazan has been proven to be a highly potent drug for Helicobacter pylori eradication, there have been no randomized trials comparing the effectiveness of regimens containing vonoprazan 20 mg daily with alternative standard strategies. We aimed to assess the efficacy, tolerance, and cost-effectiveness of quadruple therapy with vonoprazan 20 mg daily as a first-line therapy for H. pylori eradication. MATERIALS AND METHODS We conducted a single-center, open-label, noninferiority, randomized controlled study in Zhejiang, China. Treatment-naive H. pylori-positive participants (n = 234) were randomly assigned to three groups in a 1:1:1 ratio: vonoprazan 20 mg daily with amoxicillin 1000 mg, furazolidone 100 mg and colloidal bismuth 200 mg each given twice a day for 10 days (V10) or 14 days (V14), or esomeprazole 20 mg with amoxicillin 1000 mg, furazolidone 100 mg and colloidal bismuth 200 mg each given twice a day for 14 days (E14). The primary endpoint was the eradication rates in each group. The secondary endpoints were the incidence of adverse events (AEs) and compliance. RESULTS The eradication rates in the V10, V14 and E14 groups were 96.2% (89.2-99.2%), 94.9% (87.4-98.6%), and 93.6% (85.7-97.9%) in the intention-to-treat analysis, and 98.6% (92.7-100.0%), 97.4% (90.8-99.7%), and 94.8% (87.2-98.6%) in the per-protocol analysis, respectively. Quadruple therapy with vonoprazan 20 mg daily was noninferior to the esomeprazole-based regimen (Farrington and Manning test: margin 10%, significance level 2.5%). The adverse event rates were 12.8% versus 3.8% versus 6.4% in the V10, V14, and E14 groups, respectively. All regimens were well tolerated without significant differences (p = 0.096). The cost-effectiveness ratio was 1.32, 1.88, and 3.06 for the V10, V14, and E14 groups in the intention-to-treat analysis, respectively. (NCT04907747). CONCLUSIONS Vonoprazan (20 mg daily) was as effective as esomeprazole (20 mg twice a day) in quadruple therapies for the eradication of H. pylori, was more economical, and was well tolerated. In addition, the 10-day regimen of vonoprazan (20 mg daily) was comparable to the 14-day regimen.

Abstract
BACKGROUND When prescribing antibiotics, infection eradication rates, local resistance rates, and cost should be among the most essential considerations. Helicobacter pylori is among the most common infections worldwide, and it can lead to burdensome sequela for the patient and the healthcare system, without appropriate treatment. Due to constantly fluctuating resistance rates, regimens must be constantly assessed to ensure effectiveness. METHODS This was a narrative review. The sources for this review are as follows: searching on PubMed, Google Scholar, Medline, and ScienceDirect; using keywords: Helicobacter pylori, Treatment Options, Clinical Practice. RESULTS Multiple antibiotics are prescribed as part of the regimen to thwart high resistance rates. This can lead to unwanted adverse reactions and adherence issues, due to the amount and timing of medication administration, which also may contribute to resistance. Single-capsule combination capsules have reached the market to ease this concern, but brand-only may be problematic for patient affordability. Due to the previously mentioned factors, effectiveness and affordability must be equally considered. CONCLUSIONS This review will utilize guidelines to discuss current treatment options and give cost considerations to elicit the most effective regimen for the patient.

Abstract
BACKGROUND Wound closure in the complex body environment places higher requirements on suture's mechanical and biological performance. In the scenario of frequent mechanical gastric motility and extremely low pH, single functional sutures have limitations in dealing with stomach bleeding trauma where the normal healing will get deteriorated in acid. It necessitates to advance suture, which can regulate wounds, resist acid and intelligently sense stomach pH. METHODS Based on fish swim bladder, a double-stranded drug-loaded suture was fabricated. Its cytotoxicity, histocompatibility, mechanical properties, acid resistance and multiple functions were verified. Also, suture's performance suturing gastric wounds and Achilles tendon was verified in an in vivo model. RESULTS By investigating the swim bladder's multi-scale structure, the aligned tough collagen fibrous membrane can resist high hydrostatic pressure. We report that the multi-functional sutures on the twisted and aligned collagen fibers have acid resistance and low tissue reaction. Working with an implantable "capsule robot", the smart suture can inhibit gastric acid secretion, curb the prolonged stomach bleeding and monitor real-time pH changes in rabbits and pigs. The suture can promote stomach healing and is strong enough to stitch the fractured Achilles tendon. CONCLUSIONS As a drug-loaded absorbable suture, the suture shows excellent performance and good application prospect in clinical work.

Abstract
BACKGROUND & AIMS Novel, effective treatments for Helicobacter pylori infection are needed. This study evaluated the efficacy of vonoprazan, a potassium-competitive acid blocker, vs standard treatment on H pylori eradication in the United States and Europe. METHODS In a randomized, controlled, phase 3 trial, treatment-naïve adults with H pylori infection were randomized 1:1:1 to open-label vonoprazan dual therapy (20 mg vonoprazan twice daily; 1 g amoxicillin 3 times daily), or double-blind triple therapy twice a day (vonoprazan 20 mg or lansoprazole 30 mg; amoxicillin 1 g; clarithromycin 500 mg) for 14 days. The primary outcome was noninferiority in eradication rates in patients without clarithromycin- and amoxicillin-resistant strains (noninferiority margin = 10%). Secondary outcomes assessed superiority in eradication rates in clarithromycin-resistant infections, and in all patients. RESULTS A total of 1046 patients were randomized. Primary outcome eradication rates (nonresistant strains): vonoprazan triple therapy 84.7%, dual therapy 78.5%, vs lansoprazole triple therapy 78.8% (both noninferior; difference 5.9%; 95% confidence interval [CI], -0.8 to 12.6; P < .001; difference -0.3%; 95% CI, -7.4 to 6.8; P = .007, respectively). Eradication rates in clarithromycin-resistant infections: vonoprazan triple therapy 65.8%, dual therapy 69.6%, vs lansoprazole triple therapy 31.9% (both superior; difference 33.9%; 95% CI, 17.7-48.1; P < .001; difference 37.7%; 95% CI, 20.5-52.6; P < .001, respectively). In all patients, vonoprazan triple and dual therapy were superior to lansoprazole triple therapy (80.8% and 77.2%, respectively, vs 68.5%, difference 12.3%; 95% CI, 5.7-18.8; P < .001; difference 8.7%; 95% CI, 1.9-15.4; P = .013). Overall frequency of treatment-emergent adverse events was similar between vonoprazan and lansoprazole regimens (P > .05). CONCLUSION Both vonoprazan-based regimens were superior to proton pump inhibitor-based triple therapy in clarithromycin-resistant strains and in the overall study population.

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
Histamine H<sub>2</sub> receptor antagonists (H<sub>2</sub>RAs) suppress gastric acid production by blocking H<sub>2</sub> receptors in parietal cells. Studies have shown that proton pump inhibitors (PPIs) are superior to H<sub>2</sub>RAs as a treatment for acid-related disorders, such as peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD). PPIs reduce gastric acid production by irreversibly inhibiting the H<sup>+</sup>/K<sup>+</sup> ATPase pump, and they also increase gastric emptying. Although PPIs have differing pharmacokinetic properties, each PPI is effective in managing GERD and PUDs. However, PPIs have some limitations, including short plasma half-lives, breakthrough symptoms (especially at night), meal-associated dosing, and concerns associated with long-term PPI use. Potassium-competitive acid blockers (P-CABs) provide more rapid and profound suppression of intragastric acidity than PPIs. P-CABs are non-inferior to lansoprazole in healing erosive esophagitis and peptic ulcers, and may also be effective in improving symptoms in patients with non-erosive reflux disease. Acid suppressive drugs are the most commonly used drugs in clinical practice, and it is necessary to understand the pharmacological properties and adverse effects of each drug.

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
A 71-year-old woman was admitted for the treatment of diffuse large B-cell lymphoma of the ileum. She had been taking lansoprazole but was switched to vonoprazan due to epigastric discomfort. Three weeks after starting vonoprazan intake, she had a convulsive seizure, and a blood test showed hypomagnesiemia. The cause of hypomagnesemia was considered to be malabsorption of magnesium from the intestinal tract associated with vonoprazan. After discontinuation of vonoprazan, the magnesium level quickly recovered, and the seizures did not relapse. It is important to consider the risk of hypomagnesemia in patients taking vonoprazan, even for a short period of time.

Abstract
BACKGROUND AND AIMS Potassium-Competitive Acid Blockers (P-CABs) have been used in Helicobacter pylori (H. pylori) eradication therapies in recent years. However, the efficacy and safety of P-CABs compared to Proton-Pump Inhibitors (PPIs) in this setting remain controversial. METHODS The efficacy and safety of P-CABs and PPIs for H. pylori eradication were compared in a meta-analysis based on a systematic literature search of major electronic databases for relevant Randomized Controlled Trials (RCTs). RESULTS Seven studies and 1,168 patients were included. The pooled eradication rate determined by Intention-To-Treat (ITT) analysis was 90.2% for P-CAB-based and 75.5% for PPI-based triple therapy (pooled RR [95% CI] = 1.17 [1.08-1.28], p < 0.001). The Per-Protocol (PP) analysis also demonstrated significant superiority of P-CABs (pooled eradication rate = 92.4% vs. 77.8%; pooled RR [95% CI] = 1.14 [1.03-1.26], p < 0.01). In a subgroup evaluation, P-CABs were significantly better than PPIs as a first-line eradication therapy, in both the ITT analysis (pooled eradication rate = 91.8% vs. 76.4%; pooled RR [95% CI] = 1.18 [1.10-1.28], p < 0.0001) and the PP analysis (pooled eradication rate = 93.0% vs. 78.6%; pooled RR [95% CI] = 1.13 [1.02-1.26], p < 0.05). However, P-CABs were not superior to PPIs when administered as salvage therapy, as determined in the ITT (75.0% vs. 66.0%, pooled RR [95% CI] = 1.11 [0.69-1.78], p = 0.66) and PP (85.7% vs. 70.0%, pooled RR [95% CI] = 1.20 [0.82-1.75], p = 0.34) analyses. In a subgroup analysis limited to Japanese patients, both the ITT analysis (pooled eradication rate = 89.6% vs. 73.9%; RR [95% CI] = 1.21 [1.14-1.29], p < 0.01) and the PP analysis (pooled eradication rate = 92.0% vs. 75.7%; RR [95% CI] = 1.18 [1.06-1.32], p < 0.01) showed that P-CABs were significantly superior compared to PPIs as triple eradication therapy. However, in the subgroup analysis of patients from other countries, there was no significant difference in either the ITT analysis (pooled eradication rate = 93.8% vs. 85.2%; RR [95% CI] = 1.10 [0.99-1.22], p = 0.07) or PP analysis (pooled eradication rate = 95.0% vs. 90.8%; RR [95% CI] = 1.05 [0.98-1.14], p = 0.17). The incidence of adverse events associated with the two regimens did not significantly differ (P-CABs vs. PPIs: 33.6% vs. 40.0%; RR [95% CI] = 0.84 [0.71‒1.00], p = 0.05). The incidence of serious adverse events and dropout rate due to adverse events also did not differ (p = 0.44 and p = 0.67, respectively). CONCLUSIONS The efficacy of P-CAB-based triple therapy is superior to that of PPI-based triple therapy as a first-line approach to H. pylori eradication, particularly in Japanese patients. As salvage therapy, the efficacy of the two treatments did not significantly differ. The tolerability of P-CAB-based and PPI-based triple therapy was comparable, as was the incidence of adverse events.

Abstract
The diagnosis and therapy of Helicobacter pylori infection have undergone major changes based on the use the principles of antimicrobial stewardship and increased availability of susceptibility profiling. H. pylori gastritis now recognized as an infectious disease, as such there is no placebo response allowing outcome to be assessed in relation to the theoretically obtainable cure rate of 100%. The recent recognition of H. pylori as an infectious disease has changed the focus to therapies optimized to reliably achieve high cure rates. Increasing antimicrobial resistance has also led to restriction of clarithromycin, levofloxacin, or metronidazole to susceptibility-based therapies. Covid-19 resulted in the almost universal availability of polymerase chain reaction testing in hospitals which can be repurposed to utilize readily available kits to provide rapid and inexpensive detection of clarithromycin resistance. In the United States, major diagnostic laboratories now offer H. pylori culture and susceptibility testing and American Molecular Laboratories offers next-generation sequencing susceptibility profiling of gastric biopsies or stools for the six commonly used antibiotics without need for endoscopy. Current treatment recommendations include (a) only use therapies that are reliably highly effective locally, (b) always perform a test-of-cure, and (c) use that data to confirm local effectiveness and share the results to inform the community regarding which therapies are effective and which are not. Empiric therapy should be restricted to those proven highly effective locally. The most common choices are 14-day bismuth quadruple therapy and rifabutin triple therapy. Prior guidelines and treatment recommendations should only be used if proven locally highly effective.

Abstract
Gastroesophageal reflux disease (GERD) is one of the most frequent gastrointestinal disorders. Proton pump inhibitors (PPIs) are effective in healing lesions and improving symptoms in most cases, although up to 40% of GERD patients do not respond adequately to PPI therapy. Refractory GERD (rGERD) is one of the most challenging problems, given its impact on the quality of life and consumption of health care resources. The definition of rGERD is a controversial topic as it has not been unequivocally established. Indeed, some patients unresponsive to PPIs who experience symptoms potentially related to GERD may not have GERD; in this case the definition could be replaced with “reflux-like PPI-refractory symptoms.” Patients with persistent reflux-like symptoms should undergo a diagnostic workup aimed at finding objective evidence of GERD through endoscopic and pH-impedance investigations. The management strategies regarding rGERD, apart from a careful check of patient's compliance with PPIs, a possible change in the timing of their administration and the choice of a PPI with a different metabolic pathway, include other pharmacologic treatments. These include histamine-2 receptor antagonists (H2RAs), alginates, antacids and mucosal protective agents, potassium competitive acid blockers (PCABs), prokinetics, gamma aminobutyric acid-B (GABA-B) receptor agonists and metabotropic glutamate receptor-5 (mGluR5) antagonists, and pain modulators. If there is no benefit from medical therapy, but there is objective evidence of GERD, invasive antireflux options should be evaluated after having carefully explained the risks and benefits to the patient. The most widely performed invasive antireflux option remains laparoscopic antireflux surgery (LARS), even if other, less invasive, interventions have been suggested in the last few decades, including endoscopic transoral incisionless fundoplication (TIF), magnetic sphincter augmentation (LINX) or radiofrequency therapy (Stretta). Due to the different mechanisms underlying rGERD, the most effective strategy can vary, and it should be tailored to each patient. The aim of this paper is to review the different management options available to successfully deal with rGERD.

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
Helicobacter pylori (H. pylori) has so far infected more than half the global population. It is the most important and controllable risk factor for gastric cancer. The elderly, who are at a higher incidence of the infection, are also commonly found to develop antibiotic resistance. The symptoms, diagnosis, clinical features (of gastric or extra-digestive diseases), and treatment of H. pylori infection in the elderly, are different from that in the non-elderly. Health conditions, including comorbidities and combined medication have limited the use of regular therapies in elderly patients. However, they can still benefit from eradication therapy, thus preventing gastric mucosal lesions and gastric cancer. In addition, new approaches, such as dual therapy and complementary therapy, have the potential to treat older patients with H. pylori infection.

Abstract
Fexuprazan is a new drug candidate in the potassium-competitive acid blocker (P-CAB) family. As proton pump inhibitors (PPIs), P-CABs inhibit gastric acid secretion and can be used to treat gastric acid-related disorders such as gastroesophageal reflux disease (GERD). Physiologically based pharmacokinetic (PBPK) models predict drug interactions as pharmacokinetic profiles in biological matrices can be mechanistically simulated. Here, we propose an optimized and validated PBPK model for fexuprazan by integrating in vitro, in vivo, and in silico data. The extent of fexuprazan tissue distribution in humans was predicted using tissue-to-plasma partition coefficients in rats and the allometric relationships of fexuprazan distribution volumes (VSS) among preclinical species. Urinary fexuprazan excretion was minimal (0.29-2.02%), and this drug was eliminated primarily by the liver and metabolite formation. The fraction absorbed (Fa) of 0.761, estimated from the PBPK modeling, was consistent with the physicochemical properties of fexuprazan, including its in vitro solubility and permeability. The predicted oral bioavailability of fexuprazan (38.4-38.6%) was within the range of the preclinical datasets. The Cmax, AUClast, and time-concentration profiles predicted by the PBPK model established by the learning set were accurately predicted for the validation sets.

Abstract
Amoxicillin and proton pump inhibitor dual Helicobacter pylori therapy has proved not to be reliably highly effective primarily because of traditional proton pump inhibitors' inability to maintain a high intragastric pH. Clarithromycin and proton pump inhibitor H. pylori dual therapy failed in part because clarithromycin resistance emerged during therapy causing treatment failures. The combination of amoxicillin, clarithromycin, and proton pump inhibitor was subsequently undermined by increasing clarithromycin resistance. Although vonoprazan appeared to restore the effectiveness of triple therapy, the improvement was almost entirely to improved effectiveness of amoxicillin dual therapy component and resulted in the majority (>85% currently in Japan) of those receiving vonoprazan-amoxicillin plus a second antibiotic (e.g. clarithromycin, metronidazole, fluoroquinolone, or rifabutin) receiving no benefit from the second antibiotic. The results in somewhere between 2800 and 5600 kg of unnecessary clarithromycin per one million H. pylori treatment courses per year in Japan. The only contribution of the second antibiotic is to increase global antimicrobial resistance. There are now sufficient data to prove that optimized vonoprazan-amoxicillin dual therapy can reliably achieve cure rates ≥95%. This manuscript discusses use of the principles of antimicrobial stewardship to develop potassium-competitive acid blocker-containing H. pylori therapies that will reliably achieve high H. pylori cure rates with minimal or no use of excess antibiotics. Such therapies are urgently needed so that use of vonoprazan triple therapies can be curtailed while also improving overall H. pylori cure rates.

Abstract
Acid-related diseases (ARDs) are common chronic diseases of the digestive system. Proton pump inhibitors (PPIs) have become the first-line drugs for the treatment of acid-related diseases. However, PPIs display some limitations in clinical application, such as short half-life, slow action, insufficient acid inhibition, pharmacological effects affected by CYP2C19 gene polymorphism, and nocturnal acid breakthrough, which lead to insufficient symptom remission of ARDs, as well as refractoriness, relapse, and even direct decline in health-related quality of life and increased economic burden. Potassium competitive acid blockers (P-CABs) are a class of novel anti-secretory drugs, which can overcome the limitations of traditional PPIs and show satisfactory acid inhibition effect and safety in clinical application. They may become a new strategy to solve the unsatisfied medical needs in the treatment of ARDs, but their potential adverse reactions remain to be monitored. In this article, we review the challenges in the treatment of acid-related diseases, and the advantages and prospects of P-CABs in the prevention and treatment of ARDs.

Abstract
Up to 40% of patients with symptoms suspicious of gastroesophageal reflux disease (GERD) do not respond completely to proton pump inhibitor (PPI) therapy. The term "refractory GERD" has been used loosely in the literature. A distinction should be made between refractory symptoms (ie, symptoms may or may not be GERD-related), refractory GERD symptoms (ie, persisting symptoms in patients with proven GERD, regardless of relationship to ongoing reflux), and refractory GERD (ie, objective evidence of GERD despite adequate medical management). The present ESNM/ANMS consensus paper proposes use the term "refractory GERD symptoms" only in patients with persisting symptoms and previously proven GERD by either endoscopy or esophageal pH monitoring. Even in this context, symptoms may or may not be reflux related. Objective evaluation, including endoscopy and esophageal physiologic testing, is requisite to provide insights into mechanisms of symptom generation and evidence of true refractory GERD. Some patients may have true ongoing refractory acid or weakly acidic reflux despite PPIs, while others have no evidence of ongoing reflux, and yet others have functional esophageal disorders (overlapping with proven GERD confirmed off therapy). In this context, attention should also be paid to supragastric belching and rumination syndrome, which may be important contributors to refractory symptoms.

Abstract
Over the last years, there is growing evidence that microorganisms are involved in the maintenance of our health and are related to various diseases, both intestinal and extraintestinal. Changes in the gut microbiota appears to be a key element in the pathogenesis of hepatic and gastrointestinal disorders, including non-alcoholic fatty liver disease, alcoholic liver disease, liver cirrhosis, inflammatory bowel disease, irritable bowel syndrome, and Clostridium difficile - associated diarrhea. In 2019, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Nucleus for the Study of Helicobacter Pylori and Microbiota (NBEHPM), and Brazilian Federation of Gastroenterology (FBG) sponsored a joint meeting on gut microbiota and the use of prebiotics, probiotics, and synbiotics in gastrointestinal and liver diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to provide practical information about this topic, addressing the latest discoveries and indicating areas for future studies.

Abstract
OBJECTIVE A global consensus meeting was held to review current evidence and knowledge gaps and propose collaborative studies on population-wide screening and eradication of Helicobacter pylori for prevention of gastric cancer (GC). METHODS 28 experts from 11 countries reviewed the evidence and modified the statements using the Delphi method, with consensus level predefined as ≥80% of agreement on each statement. The Grading of Recommendation Assessment, Development and Evaluation (GRADE) approach was followed. RESULTS Consensus was reached in 26 statements. At an individual level, eradication of H. pylori reduces the risk of GC in asymptomatic subjects and is recommended unless there are competing considerations. In cohorts of vulnerable subjects (eg, first-degree relatives of patients with GC), a screen-and-treat strategy is also beneficial. H. pylori eradication in patients with early GC after curative endoscopic resection reduces the risk of metachronous cancer and calls for a re-examination on the hypothesis of 'the point of no return'. At the general population level, the strategy of screen-and-treat for H. pylori infection is most cost-effective in young adults in regions with a high incidence of GC and is recommended preferably before the development of atrophic gastritis and intestinal metaplasia. However, such a strategy may still be effective in people aged over 50, and may be integrated or included into national healthcare priorities, such as colorectal cancer screening programmes, to optimise the resources. Reliable locally effective regimens based on the principles of antibiotic stewardship are recommended. Subjects at higher risk of GC, such as those with advanced gastric atrophy or intestinal metaplasia, should receive surveillance endoscopy after eradication of H. pylori. CONCLUSION Evidence supports the proposal that eradication therapy should be offered to all individuals infected with H. pylori. Vulnerable subjects should be tested, and treated if the test is positive. Mass screening and eradication of H. pylori should be considered in populations at higher risk of GC.

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

Abstract
Helicobacter pylori is the only major infection for which antimicrobial therapy is not designed using the principles of antimicrobial stewardship. Traditionally, antimicrobial therapy is a susceptibility-based therapy, achieves high cure rates, and includes surveillance programs to regularly provide updated data regarding resistance, outcomes, and treatment guidelines. Current H. pylori therapies identified by trial-and-error, and treatment recommendations and guidelines are based on comparisons among regimens that rarely take into account the prevalence or effect of resistance. The majority of patients currently treated achieve suboptimal results. A paradigm shift is required to abandon current approaches and embrace antimicrobial stewardship, and therefore reliably achieve high cure rates; develop, propagate, and update best practice guidelines; and provide surveillance of local or regional susceptibility/resistance patterns. These also require timely updates to clinicians regarding the current status of resistance, antimicrobial effectiveness, and ways to prevent antimicrobial misuse to extend the useful life of currently available antibiotics. Here, we discuss the differences among current approaches to H. pylori therapy and antimicrobial stewardship and identify what is required to achieve the transition. Conceptually, the differences are significant, and the transition will likely need to be both abrupt and complete. Recommendations for therapy during the transition period are given.

Abstract
BACKGROUND A small proportion of Helicobacter pylori-infected individuals in Japan suffer failure of eradication therapy with third-line regimens containing the potent acid suppressor, vonoprazan, and a quinolone. OBJECTIVES This prospective study evaluated the efficacy and safety of rifabutin-based triple therapy with vonoprazan for refractory H pylori infection. METHODS Patients who failed H pylori eradication by clarithromycin-based first-line, metronidazole-based second-line, and sitafloxacin-based third-line therapies were recruited. After obtaining informed consent, patients received eradication therapy with vonoprazan (20 mg), amoxicillin (750 mg), and rifabutin (150 mg) twice daily for 10 days. Eradication was confirmed by a negative H pylori stool antigen or urea breath test at least 8 weeks after the end of therapy. RESULTS Nineteen patients were included in the study. All of the patients completed the course of medication. Eradication of H pylori was confirmed in all of the patients (19/19; 100%, 95% confidence interval; 83-100%). The most common adverse event was soft stool/diarrhea (4/19, 21%). No severe adverse event was observed. CONCLUSIONS Ten-day rifabutin with amoxicillin and vonoprazan triple therapy appears to be effective and safe for refractory H pylori infections. However, considering the recent publications showing high eradication rates with vonoprazan amoxicillin dual therapy, confirmation will require future studies comparing our new therapy with vonoprazan-amoxicillin dual with similar doses and duration and with vonoprazan-rifabutin dual therapy.

Abstract
Helicobacter pylori infection is a severe global health problem that is closely associated with acid-related diseases and gastric malignancies. Eradicating H. pylori is strongly recommended for lowering peptic ulcer recurrence and preventing gastric cancer. The current approved H. pylori eradication regimen combines a proton pump inhibitor (PPI) with two antibiotics. Unfortunately, this regimen failed to meet expectations mostly due to antibiotic resistance and insufficient gastric acid suppression. Vonoprazan, a novel potassium-competitive acid blocker, showed promising results as a PPI replacement. Vonoprazan inhibits gastric acid secretion by acting as a reversible competitive inhibitor against potassium ions and forming disulfide bonds with the cysteine molecule of H+/K+-ATPase. Vonoprazan has superior pharmacological characteristics over PPI, such as no requirement for acid activation, stability in acidic conditions, shorter optimum acid suppression period, and resistance to cytochrome P (CYP)2C19 polymorphism. Several comparative randomized controlled trials and meta-analyses revealed the superiority of vonoprazan in eradicating H. pylori, notably the resistant strains. The adverse effect caused by vonoprazan is long-term acid suppression that may induce elevated gastrin serum, hypochlorhydria, and malabsorption. All vonoprazan studies have only been conducted in Japan. Further studies outside Japan are necessary for universally conclusive results.

Abstract
The introduction of acid inhibition in clinical practice has revolutionized the management of acid-related diseases, leading to the virtual abolition of elective surgery for ulcer disease and relegating antireflux surgery to patients with gastroesophageal reflux disease (GERD) not adequately managed by medical therapy. Proton pump inhibitors (PPIs) are the antisecretory drugs of choice for the treatment of reflux disease. However, these drugs still leave some unmet clinical needs in GERD. PPI-refractoriness is common, and persistent symptoms are observed in up to 40-55% of daily PPI users. Potassium-competitive acid blockers (P-CABs) clearly overcome many of the drawbacks and limitations of PPIs, achieving rapid, potent, and prolonged acid suppression, offering the opportunity to address many of the unmet needs. In recent years, it has been increasingly recognized that impaired mucosal integrity is involved in the pathogenesis of GERD. As a consequence, esophageal mucosal protection has emerged as a new, promising therapeutic avenue. When P-CABS are used as add-on medications to standard treatment, a growing body of evidence suggests a significant additional benefit, especially in the relief of symptoms not responding to PPI therapy. On the contrary, reflux inhibitors are considered a promise unfulfilled, and prokinetic agents should only be used on a case-by-case basis.

Abstract
BACKGROUND More than 90% of gastric cancer cases are caused by Helicobacter pylori infections. To prevent gastric cancer, an H pylori test-and-treat strategy targeting young people has been implemented in various places in Japan. In this study, we evaluated the effectiveness of an H pylori test-and-treat strategy for second-year junior high school students in Takatsuki City. MATERIALS AND METHODS In 2014-2017, a urine-based H pylori test was used for initial screening. The final infection status was determined by a 13 C-urea breath test (13 C-UBT). Successful H pylori eradication was confirmed by 13 C-UBT 3 months after treatment. First-line eradication therapy was changed from 10 mg of rabeprazole, 750 mg of amoxicillin, and 200 mg of clarithromycin twice daily for 7 days in 2014 to 20 mg of vonoprazan, 750 mg of amoxicillin, and 200 mg of clarithromycin twice daily for 7 days in 2015-2017. Second-line eradication therapy included 10 mg of rabeprazole, 750 mg of amoxicillin, and 250 mg of metronidazole twice daily for 7 days. RESULTS In total, 8067 of 13 055 students participated this project and 206 students were diagnosed with H pylori infection. The success rate of first-line therapy was 45.9% in 2014 and 83.8% after the revised first-line therapy was administered. The final eradication rate was 98.5%. There were no severe side effects. CONCLUSION Our results support the use of the H pylori test-and-treat strategy for junior high school students as a safe approach for the prevention of gastric cancer. H pylori eradication therapy with vonoprazan could be a standard therapy in children.

Kim SY, Chung JW. Best Helicobacter pylori Eradication Strategy in the Era of Antibiotic Resistance. Antibiotics (Basel) 2020; 9:antibiotics9080436. [PMID: 32717826 PMCID: PMC7459868 DOI: 10.3390/antibiotics9080436] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2020] [Revised: 07/11/2020] [Accepted: 07/21/2020] [Indexed: 02/06/2023] Open
Abstract
Antibiotic resistance is the major reason for Helicobacter pylori treatment failure, and the increasing frequency of antibiotic resistance is a challenge for clinicians. Resistance to clarithromycin and metronidazole is a particular problem. The standard triple therapy (proton pump inhibitor, amoxicillin, and clarithromycin) is no longer appropriate as the first-line treatment in most areas. Recent guidelines for the treatment of H. pylori infection recommend a quadruple regimen (bismuth or non-bismuth) as the first-line therapy. This treatment strategy is effective for areas with high resistance to clarithromycin or metronidazole, but the resistance rate inevitably increases as a result of prolonged therapy with multiple antibiotics. Novel potassium-competitive acid blocker-based therapy may be effective, but the data are limited. Tailored therapy based on antimicrobial susceptibility test results is ideal. This review discussed the current important regimens for H. pylori treatment and the optimum H. pylori eradication strategy.

Abstract
Purpose of review Our purpose was to provide an update on methods and indications for testing and treatment selection focusing on novel modalities. Recent findings Increasing antibiotic resistance has reduced treatment effectiveness. Antibiotic resistance testing is not widely available in North America where there are insufficient resistance and susceptibility data. Quadruple regimens (bismuth-based or concomitant/non-bismuth-based) have been recommended first-line. A rifabutin-based combination product recently approved by the US Food and Drug Administration is highly effective and should simplify treatment. The potassium-competitive acid blocker vonoprazan is being evaluated as part of dual or triple combination regimens. Molecular-based genotypic testing for antibiotic resistance and an effective H. pylori vaccine remain under development. Summary Inability to test for antibiotic resistance renders treatment selection empiric. However, resistance to rifabutin and amoxicillin remains rare. Effective management continues to comprise appropriate diagnostic testing for active infection, utilization of an effective regimen, and post-treatment testing.

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.

Abstract
PURPOSE OF REVIEW Despite the many areas of unmet needs in gastroesophageal reflux disease (GERD), proton pump inhibitors (PPIs) remain the cornerstone of medical therapy. However, since their introduction, the therapeutic limitations of PPIs in GERD management have been increasingly recognized. RECENT FINDINGS In this review we discuss the new medical, endoscopic, and surgical therapeutic modalities that have been developed over the last decade. They include the potassium-competitive acid blockers (P-CABs) which provide a rapid onset, prolonged, and profound acid suppression, mucosal protectants which promote the physiological protective barrier of the esophageal mucosa, new prokinetics and neuromodulators. There are growing numbers of novel therapeutic endoscopic techniques that are under investigation or were recently introduced into the market, further expanding our therapeutic armamentarium for GERD. The development of diverse therapeutic modalities for GERD, despite the availability of PPIs, suggests that there are many areas of unmet need in GERD that will continue and drive future exploration for novel therapies.

Abstract
Objectives: This study aimed to compare the efficacy of various anti-ulcer medications in preventing delayed bleeding and promoting ulcer healing after ESD.Methods: Asystematic search was conducted for articles up to August2019. The treatments of iatrogenic ulcer were analyzed by Bayesian network meta-analysis.Results: The analysis included 28 studies. Six treatments were compared. For the prevention of delayed bleeding, potassium-competitive acid blocker (P-CAB) alone was superior to proton-pump inhibitor (PPI) alone [RR = 1.02, 95%CI (1.00, 1.05)]. Treatments based on P-CAB tended to be better than the non-P-CAB groups [RR = 1.05, 95%CI (1.03, 1.07)]. Concerning the ulcer healing rate at 4 weeks, the combined treatment of PPI and mucoprotective agent (MP) was superior to PPI alone [RR = 1.81, 95%CI (1.19, 2.76)] and P-CAB alone [RR = 2.75, 95%CI (1.02, 7.44)]. At 8 weeks, PPI+MP and P-CAB+MP tend to be superior to than the other four groups. The healing effect of MP-based therapies was better than that of non-MP groups at 4 weeks [RR = 1.63, 95%CI (1.32, 2.01)] and 8 weeks [RR = 1.06, 95%CI (1.02, 1.11)].Conclusion: P-CAB may prevent delayed bleeding, but not significantly. MP agents have the potential to heal post-ESD ulcers.

Abstract
Esophageal adenocarcinoma is inflammation-associated cancer with a recognizable preneoplastic stage, Barrett's. Barrett's describes the metaplastic transformation of esophageal squamous mucosa into columnar epithelium that typically results secondary to mucosal damage caused by acidic gastroduodenal reflux. Continued acid reflux may then result in mucosal inflammation which results in progressive inflammation-induced genetic instability that may eventuate in esophageal adenocarcinoma. Barrett's is the only recognized precursor lesion to esophageal carcinoma. Barrett's mucosa is unique among preneoplastic lesions; ablation therapy results in restitution of a squamous epithelium reducing or eliminating accumulated genetic instabilities and resetting the biological clock progressing toward invasive cancer. However, recurrence of Barrett's after ablation is common. We propose that both Barrett's and recurrence of Barrett's after ablation can be prevented and discuss how current approaches to therapy for gastroesophageal reflux disease, for Barrett's screening, chemoprevention, and ablation therapy all might be reconsidered. We propose (1) improved approaches to Barrett's prevention, (2) universal Barrett's screening by linking Barrett's screening to colon cancer screening, (3) ablation of all Barrett's mucosa along with (4) acid-suppressive-antireflux therapy tailored to prevent development of Barrett's or the recurrence of Barrett's after ablation therapy. We propose that ultimately, treatment decisions for gastroesophageal reflux disease and prevention of Barrett's and esophageal carcinoma should be based on assessing and maintaining esophageal mucosal integrity. This will require development and verification of specific measurements that reliably correlate with prevention of Barrett's. We outline the new research and technical advances needed to cost-effectively achieve these goals.

Abstract
Objectives: Peptic ulcer disease (PUD) is still common worldwide and is characterized by high mortality and morbidity. Following the decline of Helicobacter pylori infection, the detection of idiopathic PUD (IPUD) has become more frequent, making diagnosis and treatment more difficult. In this study, the clinical features and natural history of IPUD were analyzed.Methods: This was a retrospective case‒control study conducted in a tertiary care setting (University of Sassari, Italy). Records of 9,212 patients undergoing upper endoscopy from 2002 to 2018 were analyzed. Following the exclusion of H. pylori, NSAIDs, and unusual PUD causes, the remaining were labelled as IPUD. Cases (IPUD) and controls (PUD negative) were compared, adjusting for several covariates through multivariate logistic regression models.Results: Among 380 PUD, 95 were considered IPUD. The proportion rose over the study period in contrast to the decline of H. pylori-PUD. Factors significantly associated with IPUD, after adjusting for all covariates, were age (OR, 3.520; 95% CI, 1.634 - 7.585), male sex (OR, 3.126; 95% CI, 1.888 - 5.176), hospitalization (OR, 2.968; 95% CI, 1.926 - 4.575), and number of medications (OR, 2.808; 95% CI, 1.178 - 6.735). A clinical history positive for PUD was the major risk associated with IPUD (OR, 3.729; 95% CI, 2.050 - 6.785). Patients with IPUD were treated with the highest proton pump inhibitor (PPI) dose for 40-60 days. Follow up endoscopy showed a cure rate of 97.6%.Conclusion: The relative proportion of IPUD is increasing in our population in contrast to the drop of H. pylori-PUD. Treatment with high-dose PPI, and for a long duration, heals IPUD and protects from recurrence.

Abstract
OBJECTIVES To assess the efficacy and safety of vonoprazan on heartburn symptoms in patients with nonerosive reflux disease (NERD) (ClinicalTrials.gov: NCT02954848). METHODS This phase 3, double-blind, placebo-controlled study included Japanese patients aged 20 years and older with grade N/M NERD and recurrent heartburn. Patients received placebo (n = 245) or vonoprazan 10 mg (n = 238) for 4 weeks. The primary efficacy outcome was frequency of heartburn experienced by patients during the treatment period (proportion of days without heartburn). Other outcomes included cumulative improvement rates of heartburn, proportion of patients with complete heartburn resolution in the fourth week of treatment, and safety. RESULTS Compared with placebo, the proportion of days without heartburn was not significantly higher in the vonoprazan group in the full analysis (primary end point, 72.55% vs 61.50%, vonoprazan vs placebo, P = 0.0643) but was significantly higher in the per-protocol-set sensitivity analysis (P = 0.0341). Early onset of response and significantly greater cumulative improvement rates of heartburn were observed in the vonoprazan group (P = 0.0003). In a post hoc analysis, a greater proportion of patients with complete heartburn resolution in the fourth week of treatment were reported in the vonoprazan group (P = 0.0023). Incidence of treatment-emergent adverse events was similar between treatment groups (23.5% vs 23.3%); most treatment-emergent adverse events were mild in severity. DISCUSSION Although vonoprazan 10 mg was not superior to placebo with respect to proportion of days without heartburn in Japanese patients with NERD, vonoprazan had a significantly higher cumulative rate of heartburn resolution and was well tolerated.

Abstract
PURPOSE OF REVIEW Helicobacter pylori eradication has become more challenging over the past decade due to increasing antimicrobial resistance, especially to clarithromycin and levofloxacin. We identified 508 recent publications on H. pylori treatment (published between January 2018 and June 2019), focusing on the most highly clinically relevant for this review. RECENT FINDINGS Declining H. pylori eradication rates with clarithromycin triple therapy have led to most guidelines recommending 14 days bismuth-based quadruple therapy or concomitant therapy as the best initial empiric regimen. Substituting amoxicillin for tetracycline or metronidazole in quadruple therapy, and a three-in-one pill version of the regimen, also appear effective. Vonoprazan, a potent acid inhibitor, can overcome much clarithromycin resistance in triple therapy. High-dose dual therapy (proton pump inhibitor with amoxicillin) is a promising alternative approach. Reviewing resistance patterns to select suitable first-line empiric therapies is important in high resistance regions. Molecular methods to evaluate H. pylori antimicrobial susceptibility promise to be simpler than standard microbiological culture. The cost-effectiveness of antimicrobial susceptibility testing in refractory cases remains unproven. SUMMARY Updating clinicians treating H. pylori is important to combat the emerging problems of multidrug antimicrobial resistance in H. pylori strains. Truly novel approaches to H. pylori eradication are needed.
