Endoscopic findings and outcomes of gastric mucosal changes relating to potassium-competitive acid blocker and proton pump inhibitor therapy. DEN OPEN 2025; 5:e400. [PMID: 38919514 PMCID: PMC11196240 DOI: 10.1002/deo2.400] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/30/2024] [Revised: 05/27/2024] [Accepted: 06/03/2024] [Indexed: 06/27/2024]
Abstract
Gastric mucosal changes associated with long-term potassium-competitive acid blocker and proton pump inhibitor (PPI) therapy may raise concern. In contrast to that for PPIs, the evidence concerning the safety of long-term potassium-competitive acid blocker use is scant. Vonoprazan (VPZ) is a representative potassium-competitive acid blocker released in Japan in 2015. In order to shed some comparative light regarding the outcomes of gastric mucosal lesions associated with a long-term acid blockade, we have reviewed six representative gastric mucosal lesions: fundic gland polyps, gastric hyperplastic polyps, multiple white and flat elevated lesions, cobblestone-like gastric mucosal changes, gastric black spots, and stardust gastric mucosal changes. For these mucosal lesions, we have evaluated the association with the type of acid blockade, patient gender, Helicobacter pylori infection status, the degree of gastric atrophy, and serum gastrin levels. There is no concrete evidence to support a significant relationship between VPZ/PPI use and the development of neuroendocrine tumors. Current data also shows that the risk of gastric mucosal changes is similar for long-term VPZ and PPI use. Serum hypergastrinemia is not correlated with the development of some gastric mucosal lesions. Therefore, serum gastrin level is unhelpful for risk estimation and for decision-making relating to the cessation of these drugs in routine clinical practice. Given the confounding potential neoplastic risk relating to H. pylori infection, this should be eradicated before VPZ/PPI therapy is commenced. The evidence to date does not support the cessation of clinically appropriate VPZ/PPI therapy solely because of the presence of these associated gastric mucosal lesions.

Scand J Gastroenterol 2024; 59:788-797. [PMID: 38741565 DOI: 10.1080/00365521.2024.2349638] [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: 12/09/2023] [Accepted: 04/24/2024] [Indexed: 05/16/2024]
Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a common disease caused by reflux of gastric contents to the esophagus. Proton-pump inhibitors (PPIs) are recommended as a first-line therapy to treat GERD. Recently, the potassium-competitive acid inhibitors have been increasingly in use in clinical practice. We aimed to evaluate the efficacy and safety of P-CABs in GERD. METHODS We searched PubMed, the Cochrane Library, EMBASE and Web Of Science for publications regarding randomized controlled trials comparing potassium-competitive acid inhibitors to PPI monotherapy or Placebo with respect to efficacy and safety in GERD (until April 2023). The primary outcome was an absence or global symptom improvement and the incidence of adverse events in GERD. The quality of the included literature was assessed using the bias assessment tool recommended in the Cochrane Systematic Assessor's Handbook 5.1.0. We use RevMan 5.3 software for Meta-analysis, sensitivity analysis and publication bias analysis. RESULTS Of the 991 screened studies, 14 studies including 4868 participants were analyzed. The ORs for the healing rates of GERD with P-CABs versus PPI/Placebo were 2.10 (95% confidence interval [CI] 1.53-2.88), additionally, 1.09 (95% CI 1.05-1.14), 1.03 (95% CI 1.00-1.06) and 1.03 (95% CI 0.99-1.06) in Weeks 2, 4, and 8, respectively. The effectiveness rate of the experimental group was significantly higher than that of the control group (RR 1.73; 95% CI 1.27-2.36). The overall OR of Incidence of adverse events with P-CABs versus PPI/Placebo was 1.08 (95% CI 0.88-1.12). Overall, the risk of bias was low to some concerns. Furthermore, sensitivity analyses confirmed the robustness of the study's conclusion. CONCLUSIONS Our findings suggest that potassium-competitive acid inhibitors is non-inferior to PPIs as therapy for patients with GERD. The safety outcomes for potassium-competitive acid inhibitors are similar to those for PPIs.

Abstract
BACKGROUND In Chinese healthcare settings, drug selection decisions are predominantly influenced by the Pharmacy & Therapeutics Committee (PTC). This study evaluates two recently introduced potassium-competitive acid blockers, vonoprazan (VPZ) and tegoprazan (TPZ), utilizing the Evidence and Value: Impact on DEcisionMaking (EVIDEM) framework. METHODS The study employed the 10th edition of EVIDEM, which includes a core model with five domains and 13 criteria. Two independent expert panels were involved: the PTC expert panel, tasked with assigning weights using a 5-point scale, defining scoring indicators, examining the evidence matrix, scoring, and decision-making; and the evidence matrix expert panel, responsible for conducting a systematic literature review, creating the evidence matrix, and evaluating the value contributions of VPZ and TPZ. RESULTS The analysis estimated the value contributions of VPZ and TPZ to be 0.59 and 0.54, respectively. The domain of 'economic consequences of intervention' showed the most significant variation in value contribution between the two drugs, followed by 'comparative outcomes of intervention' and 'type of benefit of intervention'. CONCLUSION Employing the EVIDEM framework, VPZ's value contribution was found to be marginally superior to that of TPZ. The EVIDEM framework demonstrates potential for broader application in Chinese medical institutions.

Therap Adv Gastroenterol 2024; 17:17562848241251567. [PMID: 38903448 PMCID: PMC11189022 DOI: 10.1177/17562848241251567] [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: 01/30/2024] [Accepted: 04/12/2024] [Indexed: 06/22/2024] Open
Abstract
Background Proton-pump inhibitors (PPIs) and potassium-competitive acid blockers (P-CABs) are recommended for erosive esophagitis (EE), with good safety and tolerance. However, it is unclear which is the best treatment option for EE. Objectives This study aimed to evaluate the comparative efficacy of P-CABs and PPIs for healing EE patients, seeking an appropriate treatment choice in the 4- or 8-week treatment and standard or double dose. Design A systematic review and network meta-analysis. Data sources and methods Relevant databases were searched to collect randomized controlled trials of PPIs and P-CABs in the treatment of EE up to 31 May 2023. Studies on standard or double-dose PPIs or P-CABs which were published in English and assessed 4- or 8-week healing effects in EE were included. A network meta-analysis was performed to evaluate the efficacy of the treatments under the frequentist framework. Sensitivity and subgroup analyses of patients with different baseline EE were also conducted. Results In all, 34 studies involving 25,054 patients and 9 PPIs, 6 P-CABs, or placebo treatment interventions were included. The pooled 4-week healing rate was significantly statistically lower than the pooled 8-week healing rate for most treatments. Besides, the higher healing rate of double-dose treatment than standard-dose treatment was not observed in the initial treatment of most drugs. The main analysis only included studies conducted for both patients with and without severe EE at baseline, and the proportion of severe EE included in the study was >10%, Keverprazan 20 mg qd ranked best with a surface under the cumulative ranking curve (SUCRA) value of 84.7, followed by Ilaprazole 10 mg qd with a SUCRA value of 82.0, for the healing rate at 8 weeks. Sensitivity analysis showed that the results were robust. Subgroup analysis showed that most P-CABs had higher healing rates than PPIs, particularly for patients with severe EE. And the healing rate of Keverprazan 20 mg qd at 8 weeks ranked best in the subgroup without or with severe EE at baseline. Conclusion This study showed that an 8-week treatment seemed more effective than the 4-week treatment for healing EE patients. The healing effect of Keverprazan (20 mg qd) ranked best in 8-week treatment, for both severe and non-severe EE patients. Trial registration The study protocol was registered with INPLASY (registration number INPLASY2023120053).

Abstract
A liquid chromatography-tandem mass spectrometry method with vonoprazan fumarate-d4 as a stable isotope-labeled internal standard was developed and validated aiming at quantification of vonoprazan fumarate in human plasma for a bioequivalence study. Chromatographic separation was achieved by acetonitrile one-step protein precipitation using a gradient elution of 0.1% formic acid aqueous solution and acetonitrile with a run time of 3.65 min. Detection was carried out on a tandem mass spectrometer in multiple reaction monitoring mode via a positive electrospray ionization interface. The multiple reaction monitoring mode of precursor-product ion transitions for vonoprazan fumarate and vonoprazan fumarate-d4 were m/z 346.0 → 315.1 and 350.0 → 316.0, respectively. The linear range was 0.150-60.000 ng/ml. This method was fully validated with acceptable results in terms of selectivity, carryover, lower limit of quantification, calibration curve, accuracy, precision, dilution effect, matrix effect, stability, recovery and incurred sample reanalysis. A successful application of this method was realized in the bioequivalence study of vonoprazan fumarate tablet (20 mg) among healthy Chinese volunteers.

Abstract
BACKGROUND Vonoprazan, a potassium-competitive acid blocker, demonstrates more potent acid inhibition than proton pump inhibitors (PPIs). This study aimed to evaluate the effect of vonoprazan in patients with unproven gastroesophageal reflux disease (GERD) by comparing patients with vonoprazan-refractory heartburn with those with PPI-refractory heartburn. METHODS This study included 104 consecutive patients with vonoprazan- or PPI-refractory heartburn (52 patients each), no erosive esophagitis on endoscopy and who underwent combined multichannel intraluminal impedance-pH (MII-pH) testing with vonoprazan/PPI discontinuation. Patients' backgrounds, symptom scores from four questionnaires, MII-pH results and high-resolution manometry results were compared between the two groups. RESULTS The vonoprazan group demonstrated significantly higher GERD symptoms and scores of abdominal pain and diarrhea on the Gastrointestinal Symptom Rating Scale questionnaire. MII-pH results revealed that the vonoprazan group demonstrated 40.4%, 17.3%, and 42.3% and the PPIs group exhibited 26.9%, 17.3%, and 55.8% of abnormal acid reflux [true non-erosive reflux disease (NERD)], reflux hypersensitivity and functional heartburn, respectively. The vonoprazan group demonstrated higher true NERD rates but with no significant difference (p = 0.307). Among the vonoprazan group, eight patients with true NERD underwent another MII-pH test on vonoprazan, and all cases demonstrated normal acid exposure times (0.0% [0.0-0.3]). CONCLUSION Patients with unproven GERD with vonoprazan-refractory heartburn demonstrated more symptoms, including not only GERD symptoms but also functional dyspepsia and irritable bowel syndrome symptoms, than those with PPI-refractory heartburn.

Vonoprazan is superior to lansoprazole for healing of severe but not mild erosive esophagitis: A systematic review with meta-analysis of randomized controlled trials. J Gastroenterol Hepatol 2024; 39:988-999. [PMID: 38353152 DOI: 10.1111/jgh.16486] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 12/12/2023] [Accepted: 12/27/2023] [Indexed: 06/19/2024]
Abstract
BACKGROUND AND AIM Healing rates of severe erosive esophagitis (EE; Los Angeles [LA] Grade C/D) in patients treated with a proton pump inhibitor (PPI) is suboptimal (~60-70%). Vonoprazan, a potassium-competitive acid blocker, is suggested to have better healing rates in patients with severe EE. This meta-analysis compares the efficacy and safety of vonoprazan 20 mg versus lansoprazole 30 mg daily in healing EE, specifically in those with LA Grade C/D. METHODS We searched MEDLINE, Embase, and CENTRAL on May 24, 2023. Studies that randomized EE patients to vonoprazan 20 mg daily or lansoprazole 30 mg daily and compared healing rates were included. The risk of bias was assessed using Cochrane's Risk of Bias 2 tool. The fixed-effect model was used to obtain the pooled efficacy and safety outcomes. Subgroup analysis was done to compare healing rates in mild (LA Grade A/B) versus severe EE and based on study location. RESULTS Four randomized controlled trials (RCTs) with low risks of bias comprising 2208 participants were included. Vonoprazan 20 mg was superior to lansoprazole 30 mg daily in healing severe EE at all weeks (Week 2 RR 1.294 [95% CI 1.169-1.433], Week 4 1.160 [1.059-1.270], and Week 8 1.175 [95% CI 1.107-1.247]), but was similar for mild EE at all weeks (P-interaction < 0.01). Vonoprazan 20 mg was more efficacious than lansoprazole 30 mg at Week 8 in Western versus Asian studies (P-interaction < 0.01). Any, serious, and drug-related treatment-emergent adverse events were comparable between groups. CONCLUSION Vonoprazan 20 mg is superior to lansoprazole 30 mg for healing severe EE but not mild EE. Vonoprazan 20 mg daily has a similar safety profile to lansoprazole 30 mg daily.

Abstract
PURPOSE OF REVIEW Potassium-competitive acid blockers (PCABs) represent a new class of compounds for the treatment of acid-related disorders. Recent FDA approval of the PCAB vonoprazan for erosive esophagitis has started an important new approach to acid-related disorders. RECENT FINDINGS Compared to conventional proton pump inhibitors (PPIs), PCABs provide more rapid, potent, and sustained suppression of gastric acid with faster and more durable symptom relief. Studies have demonstrated the efficacy of PCABs for erosive esophagitis, nonerosive reflux disease, and peptic ulcer disease including H. pylori. However, the PCAB vonoprazan was only approved in the US as part of combination therapy for eradication of H. pylori. Clinical trials have now demonstrated noninferiority of vonoprazan to lansoprazole for treatment of erosive esophagitis, particularly noting superiority of vonoprazan in patients with severe esophagitis resulting in FDA approval of vonoprazan for treatment of erosive esophagitis. Emerging data suggests a possible utility of vonoprazan for PPI-resistant gastroesophageal reflux disease (GERD) and on-demand therapy for nonerosive reflux disease. Vonoprazan is generally well tolerated but long-term safety data is not well established. SUMMARY The PCAB vonoprazan is a newly FDA approved treatment option for erosive esophagitis. Its possible role in PPI-resistant GERD and nonerosive reflux disease warrants further investigation.

[PMID: 38892973 PMCID: PMC11172701 DOI: 10.3390/jcm13113262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2024] [Revised: 05/19/2024] [Accepted: 05/22/2024] [Indexed: 06/21/2024] Open
Abstract
Background: Fexuprazan (Fexuclue®; Daewoong Pharmaceutical Co., Ltd., Seoul, Korea) is a novel potassium-competitive acid blocker (P-CAB). This multi-center, randomized, double-blind, active-controlled, parallel-group, therapeutic confirmatory, phase III study was conducted to assess its efficacy and safety compared with esomeprazole (Nexium®; AstraZeneca, Gothenburg, Mölndal, Sweden) in Korean patients with erosive esophagitis (EE). Methods: This study evaluated patients diagnosed with EE at a total of 25 institutions in Korea between 13 December 2018 and 7 August 2019. After voluntarily submitting a written informed consent form, the patients were evaluated using a screening test and then randomized to either of the two treatment arms. The proportion of the patients who achieved the complete recovery of mucosal breaks at 4 and 8 weeks, the proportion of those who achieved the complete recovery of heartburn at 3 and 7 days and 8 weeks, and changes in the GERD-Health-Related Quality of Life Questionnaire (GERD-HRQL) scores at 4 and 8 weeks from baseline served as efficacy outcome measures. The incidence of treatment-emergent adverse events (TEAEs) and adverse drug reactions (ADRs) and the serum gastrin levels served as safety outcome measures. Results: The study population comprised a total of 231 patients (n = 231) with EE, including 152 men (65.80%) and 79 women (34.20%); their mean age was 54.37 ± 12.66 years old. There were no significant differences in the efficacy and safety outcome measures between the two treatment arms (p > 0.05). Conclusions: It can be concluded that the efficacy and safety of Fexuclue® are not inferior to those of esomeprazole in Korean patients with EE.

Abstract
Introduction The eradication rate of Helicobacter pylori (H. pylori) has decreased due to antibiotics resistance and inadequate acid suppression. Vonoprazan is a novel potassium-competitive acid blocker (P-CAB), which has a rapid and sustained acid inhibitory effect and may be more effective than conventional proton pump inhibitors (PPIs) in H. pylori eradication. Aim to study the efficacy and safety of vonoprazan as a component of first-line H. pylori eradication treatment compared with conventional PPI-based therapy. Material and methods This randomised (one to one) non-blinded study was conducted on 400 consecutive proven H. pylori infected patients, of whom 200 received vonoprazan-based triple therapy, while 200 patients received PPI-based triple therapy for 14 days. The study outcomes were evaluated as eradication rate and adverse events in both patient groups. Results The eradication rate was 86% in the vonoprazan group and 74.5% in the PPI group. The vonoprazan eradication rate was significantly higher than that of PPIs (p = 0.004). There was no significant difference regarding adverse events between both patient groups. Conclusions Vonoprazan-based therapy was more effective than PPI-based therapy as a first-line H. pylori eradication treatment. Vonoprazan was generally safe and well tolerated.

Abstract
INTRODUCTION Los Angeles grade C/D esophagitis is a severe manifestation of gastroesophageal reflux disease that require active treatment and close follow-up. Potassium competitive acid blockers (P-CAB) are promising alternatives to proton pump inhibitors (PPI). We aimed to compare the efficacy and safety of P-CAB and PPI in healing grade C/D esophagitis to aid clinical decision-making. METHODS A systematic literature search was performed using PubMed, MEDLINE, and Cochrane Central Register of Controlled Trials. Randomized controlled trials were eligible for inclusion if efficacy of P-CAB and PPI in healing grade C/D esophagitis was reported. Pooled risk ratios and risk difference with 95% credible intervals were used to summarize estimated effect of each comparison. The benefit of treatments was ranked using the surface under the cumulative probability ranking score. RESULTS Of 5,876 articles identified in the database, 24 studies were eligible. Studies included incorporated 3 P-CAB (vonoprazan, tegoprazan, and keverprazan) and 6 PPI (lansoprazole, esomeprazole, omeprazole, rabeprazole extended-release (ER), pantoprazole, and dexlansoprazole). Based on the failure to achieve mucosal healing, 20 mg of vonoprazan q.d. ranked the first among PPI in initial and maintained healing of grade C/D esophagitis (surface under the cumulative probability ranking score = 0.89 and 0.87, respectively). Vonoprazan had similar risk of incurring adverse events, severe adverse events, and withdrawal to drug when compared with PPI. For those who attempted lower maintenance treatment dose, 10 mg of vonoprazan q.d. was a reasonable choice, considering its moderate efficacy and safety. DISCUSSION Vonoprazan has considerable efficacy in initial and maintained healing of grade C/D esophagitis compared with PPI, with moderate short-term and long-term safety.

Abstract
BACKGROUND Erosive esophagitis (EE) is a gastroesophageal reflux disease characterized by mucosal breaks in the esophagus. Proton pump inhibitors are widely used as maintenance therapy for EE, but many patients still relapse. In this trial, we evaluated the noninferiority of vonoprazan vs. lansoprazole as maintenance therapy in patients with healed EE. METHODS We performed a double-blind, double-dummy, multicenter, phase 3 clinical trial among non-Japanese Asian adults with endoscopically confirmed healed EE from April 2015 to February 2019. Patients from China, South Korea, and Malaysia were randomized to vonoprazan 10 mg or 20 mg once daily or lansoprazole 15 mg once daily for 24 weeks. The primary endpoint was endoscopically confirmed EE recurrence rate over 24 weeks with a noninferiority margin of 10% using a two-sided 95% confidence interval (CI). Treatment-emergent adverse events (TEAEs) were recorded. RESULTS Among 703 patients, EE recurrence was observed in 24/181 (13.3%) and 21/171 (12.3%) patients receiving vonoprazan 10 mg or 20 mg, respectively, and 47/184 (25.5%) patients receiving lansoprazole (differences: -12.3% [95% CI, -20.3% to -4.3%] and -13.3% [95% CI, -21.3% to -5.3%], respectively), meeting the primary endpoint of noninferiority to lansoprazole in preventing EE recurrence at 24 weeks. Evidence of superiority (upper bound of 95% CI <0%) was also observed. At 12 weeks, endoscopically confirmed EE recurrence was observed in 5/18, 2/20, and 7/20 of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. TEAEs were experienced by 66.8% (157/235), 69.0% (156/226), and 65.3% (158/242) of patients receiving vonoprazan 10 mg, vonoprazan 20 mg, and lansoprazole, respectively. The most common TEAE was upper respiratory tract infection in 12.8% (30/235) and 12.8% (29/226) patients in vonoprazan 10 mg and 20 mg groups, respectively and 8.7% (21/242) patients in lansoprazole group. CONCLUSION Vonoprazan maintenance therapy was well-tolerated and noninferior to lansoprazole for preventing EE recurrence in Asian patients with healed EE.

Abstract
BACKGROUND Gastroesophageal Reflux Disease (GERD) is a prevalent condition in Brazil, affecting 12% to 20% of the urban population, with significant implications for patient quality of life and potential for complications. OBJECTIVE This paper focuses on the recent update of the Brazilian guidelines for GERD, a necessary revision due to advancements in knowledge and practice since the last publication over a decade ago. The update pays particular attention to the role and safety of proton pump inhibitors (PPIs), acknowledging the growing concerns about their long-term use, adverse events, and overprescription. METHODS The methodology of the guideline update involved an extensive literature review in multiple languages (English, French, Italian, Spanish, and Portuguese), drawing from major databases such as Medline, Embase, and SciELO-Lilacs. RESULTS This comprehensive approach resulted in a carefully curated selection of studies, systematic reviews, and meta-analyses, specifically focusing on PPIs and other therapeutic strategies for GERD. The updated guidelines are presented in a user-friendly question-and-answer format, adhering to the PICO system (Population, Intervention, Comparison, Outcomes) for clarity and ease of interpretation. The recommendations are supported by robust scientific evidence and expert opinions, enhancing their practical applicability in clinical settings. To ensure the reliability and clarity of the recommendations, the GRADE system (Grading of Recommendations Assessment, Development, and Evaluation) was employed. This system categorizes the strength of recommendations as strong, weak, or conditional and classifies evidence quality as high, moderate, low, or very low. These classifications provide insight into the confidence level of each recommendation and the likelihood of future research impacting these guidelines. CONCLUSION The primary aim of these updated guidelines is to offer practical, evidence-based advice for the management of GERD in Brazil, ensuring that healthcare professionals are equipped with the latest knowledge and tools to deliver optimal patient care. BACKGROUND •Gastrointestinal specialists rely heavily on guidelines to manage digestive pathologies effectively. The Brazilian clinical guideline for therapeutic management of gastroesophageal reflux disease (GERD) is an invaluable tool for these specialists. BACKGROUND •It critically analyzes practical aspects of therapy through 12 questions covering a wide range of topics, from behavioral measures to surgical and endoscopic indications. BACKGROUND •The recommendations in this guideline are justified using the GRADE system (Grading of Recommendations Assessment, Development, and Evaluation), and experienced experts provide comments and suggestions at the end of each question.

Abstract
BACKGROUND Both vonoprazan and proton pump inhibitors (PPIs) are currently used to treat artificial ulcers after gastric endoscopic submucosal dissection. However, evidence-based medicine proving the efficacy of vonoprazan is still lacking. Therefore, this meta-analysis aimed to compare the efficacy of vonoprazan and PPIs for the treatment of artificial ulcers after gastric endoscopic submucosal dissection. METHODS The PubMed, EMBASE and Cochrane Library databases were searched up to September 2023 for related randomized controlled trials (RCTs). RCTs that compared the efficacy of vonoprazan and PPIs in treating artificial gastric ulcers after gastric endoscopic submucosal dissection were included. Two independent reviewers screened the included studies, extracted the data and assessed the risk of bias. The following outcomes were extracted for comparison: ulcer healing rate, ulcer shrinkage rate, delayed postoperative bleeding rate, and ulcer perforation rate. RESULTS Nine randomized controlled trials involving 926 patients were included. The pooled results showed that vonoprazan had a significantly lower rate of delayed postoperative bleeding than did PPIs (RR = 0.46; 95% CI = 0.23-0.91; P = 0.03). No significant differences were found in terms of ulcer healing, shrinkage rates, or ulcer perforation rates between vonoprazan and PPIs. CONCLUSIONS Compared with PPIs, vonoprazan is superior at reducing delayed postoperative bleeding after endoscopic submucosal dissection. However, further studies are needed to prove the efficacy of vonoprazan. SYSTEMATIC REVIEW REGISTRATION Identifier CRD42024509227.

Abstract
Acid inhibitors have been considered in treating gastroesophageal reflux-related cough (GERC). Compared to proton pump inhibitors (PPIs), potassium-competitive acid blockers (P-CABs) have more potent and durable effects on anti-acid secretion. However, whether vonoprazan and esomeprazole have different therapeutic effects on GERC remains unknown. Patients diagnosed with GERC were enrolled in our study and randomly treated with vonoprazan (20 mg, once daily, P-CAB) or esomeprazole (20 mg, twice daily, PPI) for two months. A prokinetic agent was also administered. Patients were followed up once a month. Cough severity visual analogue scale (VAS) was measured as the primary outcome, while cough symptom score (CSS) and scores for cough-related quality-of-life or reflux-related symptoms were the secondary endpoints. A total of 50 patients completed the study, with 25 patients in each group. P-CAB and PPI groups showed similar decreases in cough severity VAS and CSS scores after the 2-month treatment (all P < 0.001). For quality-of-life, the Leicester Cough Questionnaire (LCQ) score increased significantly from baseline in both groups, but the P-CAB group had greater improvement and a higher LCQ score in month 2 (all P ≤ 0.05). For reflux-related symptoms, the Hull Airway Reflux Questionnaire (HARQ) score declined substantially over time in the P-CAB group, while the reflux symptom index (RSI) score decreased in both groups. The P-CAB group tended to have a lower HARQ (P = 0.051) and RSI (P = 0.069) scores in month 2. In conclusion, vonoprazan may be comparable to esomeprazole in cough symptom relief in GERC during the 2-month treatment period, but possibly provides better gains on classic reflux symptoms and quality-of-life. The long-term efficacy of P-CABs on GERC may be worth further exploration. Trial Registration: Chinese Clinical Trial Registry Identifier: ChiCTR2200067089.

Abstract
Gastroesophageal reflux disease (GERD) is common, with increasing worldwide disease prevalence and high economic burden. A significant number of patients will remain symptomatic following an empiric proton pump inhibitor (PPI) trial. Persistent symptoms despite PPI therapy are often mislabeled as refractory GERD. For patients with no prior GERD evidence (unproven GERD), testing is performed off antisecretory therapy to identify objective evidence of pathologic reflux using criteria outlined by the Lyon consensus. In proven GERD, differentiation between refractory symptoms (persisting symptoms despite optimized antisecretory therapy) and refractory GERD (abnormal reflux metrics on ambulatory pH impedance monitoring and/or persistent erosive esophagitis on endoscopy while on optimized PPI therapy) can direct subsequent management. While refractory symptoms may arise from esophageal hypersensitivity or functional heartburn, proven refractory GERD requires personalization of the management approach, tapping from an array of non-pharmacologic, pharmacologic, endoscopic, and surgical interventions. Proper diagnosis and management of refractory GERD is critical to mitigate undesirable long-term complications such as strictures, Barrett's esophagus, and esophageal adenocarcinoma. This review outlines the diagnostic workup of patients presenting with refractory GERD symptoms, describes the distinction between unproven and proven GERD, and provides a comprehensive review of the current treatment strategies available for the management of refractory GERD.

Abstract
Background and Aim Previous studies on age differences in proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) have found that stenosis and bleeding complications were significantly more common in the elderly than in the non-elderly. We sought to examine differences between two groups of elderly (75 years or older) and non-elderly (<75 years) patients with (PPI)-resistant severe RE and also the efficacy of vonoprazan (VPZ) in these patients. Methods There were 14 patients in the elderly group and 15 in the non-elderly group. Information was obtained on patient background (sex, body mass index [BMI], gastric mucosal atrophy, and the presence of hernia and collagen disease), and all patients underwent the saliva secretion test and esophagogastroduodenoscopy (EGD). The saliva secretion test (amount of saliva secreted, salivary pH, and the acid-buffering capacity) was performed by chewing sugar-free gum for 3 min before EGD. The efficacy of VPZ in both groups was also assessed. Results Saliva secretion, sex, BMI, and the presence of gastric mucosal atrophy did not significantly differ between the two groups. The number of hernias larger than 4 cm was significantly higher in the elderly PPI-resistant group, and significantly more patients had collagen disease in the non-elderly group. The efficacy of VPZ was not significantly different between the two groups; however, 10 patients in the non-elderly group had collagen disease, and 4 did not achieve esophageal mucosal healing even with VPZ 20 mg. Conclusion The number of large hernias (>4 cm) was significantly higher in the elderly group, while significantly more non-elderly patients had collagen disease. In the non-elderly group with scleroderma, the efficacy of VPZ 20 mg may not be sufficient.

Abstract
To investigate the risk of acute kidney injury (AKI) in patients with cancer following the initiation of proton pump inhibitors (PPIs) and potassium-competitive acid blocker (PCAB), considering sex and anti-cancer drug use. We conducted a self-controlled case-series study using the Japan Medical Data Center claims data from 12422 patients with cancer who were prescribed PPIs or PCAB between January 2017 and December 2019. Considering the timing of PPI or PCAB, control period (days -120 to -1), risk period 1 (days 0 to +30), and risk period 2 (days +31 to +365) were defined. To assess the incidence rate ratio (IRR) and 95% confidence interval (CI) as the risk ratio, we adjusted for anti-cancer drugs to assess the risk of AKI. Additionally, we also examined sex differences to identify the risk of AKI. AKI was observed in risk period 1 [2.05 (1.12-3.72), p = 0.0192], but a slight reduction was noted in risk period 2 [0.60 (0.36-1.00), p = 0.0481]. A sex-specific increase in the risk of AKI was observed only in males during risk period 1 [2.18 (1.10-4.32), p = 0.0260], with a reduction in risk period 2 [0.48 (0.26-0.89), p = 0.0200]. We identified an increased risk of AKI in patients with cancer starting PPIs or PCAB particularly in males within 30 d after PPI or PCAB initiation, emphasizing the need for vigilant monitoring and management of AKI in this patient population.

Wang D, Zhou D, Liu X, Xu Z, Bai T, Hou X. Different dosages of vonoprazan for gastroesophageal reflux disease: study protocol for a pragmatic, crossover-cluster, randomized controlled trial with patient preference arms. Trials 2023; 24:778. [PMID: 38041136 PMCID: PMC10691065 DOI: 10.1186/s13063-023-07760-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2023] [Accepted: 10/27/2023] [Indexed: 12/03/2023] Open
Abstract
BACKGROUND Vonoprazan results in more potent acid suppression for gastroesophageal reflux disease (GERD) than proton pump inhibitors. It has only been approved for treating erosive esophagitis in China, but 30-40% of GERD patients cannot achieve the goal of treatment with vonoprazan 20 mg daily. This study aims to investigate whether vonoprazan could relieve the symptoms of Chinese patients with non-erosive reflux disease (NERD) and whether increased dosage or different times of dosing could increase the response rate of GERD. METHODS This study is a pragmatic, open-label, crossover-cluster, randomized controlled trial with patient preference arms. Two thousand eight hundred eighty patients with GERD from 48 hospitals in China will be enrolled. These hospitals will be divided into a compulsory randomization cluster (24 hospitals) and a patient preference cluster (24 hospitals). Patients in the compulsory randomization cluster will be randomized to three regimens according to the crossover-cluster randomization. Patients in the patient preference cluster may choose to receive any regimen if they have a preference; otherwise, patients will be randomly assigned. The three treatment regimens will last 4 weeks, including (1) vonoprazan 20 mg p.o. after breakfast, (2) vonoprazan 20 mg p.o. after dinner, and (3) vonoprazan 20 mg p.o. after breakfast and after dinner. Patients will attend a baseline visit, a 4-week e-diary, a fourth-week visit, and a sixth-month visit online. The primary outcome is the symptom relief rate of all patients after 4-week therapy. Secondary outcomes include the healing rate of EE patients, the severity of symptoms, compliance with the therapy at the fourth-week follow-up visit, recurrent symptoms, and the frequency of self-conscious doctor visits at the sixth-month follow-up visit. DISCUSSION This trial will explore the effectiveness of different regimens of vonoprazan that will be implemented with GERD patients in China. The randomization with patient preferences considered and the crossover-cluster component may improve the robustness and extrapolation of study conclusions.

Abstract
Reflux hypersensitivity (RH) is one of the phenotypes of gastroesophageal reflux disease. The latest Rome IV defines RH as a condition with typical reflux symptoms and positive reflux-symptom association despite normal acid exposure. Subsequently, the Lyon consensus proposed detailed cutoff values for the criteria on the basis of experts' consensus. Rome IV brought a clear-cut perspective into the pathophysiology of gastroesophageal reflux disease and the importance of esophageal hypersensitivity. This perspective can be supported by the fact that other functional gastrointestinal disorders such as irritable bowel syndrome and functional dyspepsia often overlap with RH. Although several possible pathophysiological mechanisms of esophageal hypersensitivity have been identified, there is still unmet medical needs in terms of treatment for this condition. This review summarizes the current knowledge regarding RH.

Abstract
BACKGROUND Non-erosive reflux disease (NERD) symptoms are often episodic, making on-demand treatment an attractive treatment approach. AIMS We compared the efficacy and safety of on-demand vonoprazan versus placebo in patients with NERD. METHODS Patients with NERD, defined as heartburn for ≥6 months and for ≥4/7 consecutive days with normal endoscopy, received once-daily vonoprazan 20 mg during a 4-week run-in period. Patients without heartburn during the last 7 days and with ≥80% study drug and diary compliance were randomised 1:1:1:1 to vonoprazan 10, 20, 40 mg or placebo on-demand for 6 weeks. The primary endpoint was the percentage of evaluable heartburn episodes completely relieved within 3 h of on-demand dosing and sustained for 24 h. RESULTS Of 458 patients in the run-in period, 207 entered the on-demand period. In the vonoprazan 10 mg group, 56.0% (201/359) of evaluable heartburn episodes met the criteria for complete and sustained relief; 60.6% (198/327) in the 20 mg group; and 70.0% (226/323) in the 40 mg group, compared with 27.3% (101/370) in the placebo group (p < 0.0001 versus placebo for each vonoprazan group). By 1 h post-dose, vonoprazan was associated with complete relief of significantly more heartburn episodes compared with placebo. No serious treatment-emergent adverse events were reported. CONCLUSION On-demand vonoprazan may be a potential alternative to continued daily acid suppression therapy for the relief of episodic heartburn in patients with NERD. CLINICALTRIALS gov: NCT04799158.

Efficacy of Vonoprazan vs. Pantoprazole or Non-acid Suppression in Prevention of Post-variceal Ligation Ulcer Bleeding in Portal Hypertension: A Multi-arm Randomized Controlled Trial. J Clin Exp Hepatol 2023; 13:962-971. [PMID: 37975046 PMCID: PMC10643493 DOI: 10.1016/j.jceh.2023.05.008] [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: 02/24/2023] [Accepted: 05/15/2023] [Indexed: 11/19/2023] Open
Abstract
Background Up-to-date data about the role of acid suppression therapy e.g. proton-pump inhibitors; to reduce post-endoscopic variceal ligation (EVL) ulcer-bleeding are conflicting. Vonoprazan; a recently introduced potassium-competitor acid blocker, has not been studied to prevent post-EVL ulcer/bleeding. The aim was to evaluate the efficacy of vonoprazan vs. pantoprazole or non-acid suppression to prevent post-EVL ulcer/bleeding in portal hypertension patients. Material and methods We enrolled 275 portal hypertension patients undergoing EVL in a three-arm randomized, single-blind, controlled study. A clinico-laboratory baseline evaluation was performed. Following EVL, patients were randomly and equally assigned to receive vonoprazan 20mg once daily, pantoprazole 40 mg once daily, or no acid suppression therapy. Post-EVL ulcer bleeding, ulcer dimensions, odynophagia as well as vonoprazan safety were evaluated after 2 weeks of EVL. Results Post-EVL ulcer bleeding occurred among 2.15% of vonoprazan, 8.7% of pantoprazole, and 14.2% of the non-acid suppression groups (P < 0.001). Post-ligation ulcer frequency and dimensions were higher among non-acid suppression and pantoprazole groups vs. vonoprazan (P < 0.05). Chest pain and odynophagia were encountered among 73.6% and 54.9% of the non-acid suppression group vs. 39.6% and 45.1% in pantoprazole, and 17.2% and 21.5% in vonoprazan groups, respectively (P < 0.05). There were no vonoprazan-related adverse events. Non-use of vonoprazan was the strongest independent predictor for post-EVL bleeding. Conclusion Short course of vonoprazan 20 mg/day is safe and superior to pantoprazole 40 mg/day in the reduction of post-EVL ulcer dimensions at 2 weeks post-EVL, and prevention of ulcer-related bleeding. Acid suppression is superior to no acid suppression to prevent post-EVL complications.

Abstract
BACKGROUND AND AIM While proton pump inhibitor (PPI) therapy has proven to be effective in managing gastroesophageal reflux disease (GERD), a notable portion of patients who experience GERD symptoms may not respond to this treatment. Research suggests that roughly 30% of individuals with a presumed GERD diagnosis may continue to experience symptoms, whether partially or completely, even when receiving PPI therapy. The aim of this study was to assess the treatment of gastrointestinal diseases with a novel potassium-competitive acid blocker (P-CAB), vonoprazan, in terms of its effectiveness and safety in the Pakistani population. METHODS This prospective, multicenter, observational study was conducted in Pakistan. This study included 1,642 patients from January 2023 to August 2023, aged 18 years, with gastrointestinal disorders. All demographic data, medical history, GERD severity assessment questionnaire (GerdQ), and laboratory parameters, including stool assessment for Helicobacter pylori (H. pylori), were observed. Patients were orally treated with vonoprazan at doses of 10 mg or 20 mg, once or twice daily. Statistical analysis was done by one-way ANOVA. RESULTS Out of 1,642 patients, 840 (51.2%) were males and 802 (48.8%) were females, with a mean age of 39.81±14.61 years. The mean GerdQ score at baseline was 20.37±15.87, 7.24±8.15 at the second week of treatment, and 3.70±6.31 at the fourth week of treatment (p<0.001). 90.74% of patients achieved H. pylori eradication. Most patients were acid regurgitation and heartburn-free for >70% of days. Most of the patients, 1,283 (78.13%), exhibited good treatment compliance. Mild adverse events were reported in 37 (2.3%) patients. CONCLUSIONS The use of vonoprazan significantly reduced the likelihood of GERD by improving symptoms and was also highly effective in the elimination of H. pylori infections. Vonoprazan was generally well tolerated.

Abstract
BACKGROUND Vonoprazan is a new potassium-competitive acid blocker (P-CAB) that was recently approved by the FDA. It is associated with a fast onset of action and a longer acid inhibition time. Vonoprazan-containing therapy for helicobacter pylori eradication is highly effective and several studies have demonstrated that a vonoprazan-antibiotic regimen affects gut microbiota. However, the impact of vonoprazan alone on gut microbiota is still unclear.Please check and confirm the authors (Maria Cristina Riascos, Hala Al Asadi) given name and family name are correct. Also, kindly confirm the details in the metadata are correct.Yes they are correct. METHODS: We conducted a prospective randomized 12-week experimental trial with 18 Wistar rats. Rats were randomly assigned to one of 3 groups: (1) drinking water as negative control group, (2) oral vonoprazan (4 mg/kg) for 12 weeks, and (3) oral vonoprazan (4 mg/kg) for 4 weeks, followed by 8 weeks off vonoprazan. To investigate gut microbiota, we carried out a metagenomic shotgun sequencing of fecal samples at week 0 and week 12.Please confirm the inserted city and country name is correct for affiliation 2.Yes it's correct. RESULTS For alpha diversity metrics at week 12, both long and short vonoprazan groups had lower Pielou's evenness index than the control group (p = 0.019); however, observed operational taxonomic units (p = 0.332) and Shannon's diversity index (p = 0.070) were not statistically different between groups. Beta diversity was significantly different in the three groups, using Bray-Curtis (p = 0.003) and Jaccard distances (p = 0.002). At week 12, differences in relative abundance were observed at all levels. At phylum level, short vonoprazan group had less of Actinobacteria (log fold change = - 1.88, adjusted p-value = 0.048) and Verrucomicrobia (lfc = - 1.76, p = 0.009).Please check and confirm that the author (Ileana Miranda) and their respective affiliation 3 details have been correctly identified and amend if necessary.Yes it's correct. At the genus level, long vonoprazan group had more Bacteroidales (lfc = 5.01, p = 0.021) and Prevotella (lfc = 7.79, p = 0.001). At family level, long vonoprazan group had more Lactobacillaceae (lfc = 0.97, p = 0.001), Prevotellaceae (lfc = 8.01, p < 0.001), and less Erysipelotrichaceae (lfc = - 2.9, p = 0.029). CONCLUSION This study provides evidence that vonoprazan impacts the gut microbiota and permits a precise delineation of the composition and relative abundance of the bacteria at all different taxonomic levels.

Abstract
AIMS The new modified-release formulation of tegoprazan, a novel potassium-competitive acid blocker, is expected to improve the management of acid-related disease, including nocturnal acid breakthrough, by prolonging the duration of acid suppression. This study aimed to explore the pharmacokinetics (PK) and pharmacodynamics (PD) of various combinations of tegoprazan with immediate-release (IR) and delayed-release (DR) formulations. METHODS A three-cohort, open-label, randomized, single-dose, three-treatment, six-sequence, three-period crossover study was conducted. Various combinations of tegoprazan IR and DR formulations (50, 75 or 100 mg) were administered orally once per period. The 24-h intragastric pH was monitored before and after each administration. PK blood samples were collected for up to 48 h. PK and PD were compared among treatments. RESULTS Eighteen healthy Korean subjects completed the study. All treatment groups showed intragastric pH above 4 approximately 1 h following tegoprazan administration. Among the various combinations, the IR and DR combination at a 1:1 ratio induced greater gastric acid suppression (%Time pH ≥ 4) than IR alone in each dose group, both for 24 h (50 mg; 59% vs. 52%, P = .2188, 95% confidence interval [CI] -6.92-22.27, 100 mg; 85% vs. 70%, P < .05, 95% CI 8.92-22.19) and at night (50 mg; 27% vs. 16%, P = .1563, 95% CI -11.79-37.71, 100 mg; 77% vs. 49%, P < .05, 95% CI 16.14-42.98), with similar systemic exposure. CONCLUSIONS The combinatorial tegoprazan in the IR and DR 1:1 ratio formulation was found to induce stronger gastric acid suppression throughout the day and at night, compared to the conventional IR formulation.

Abstract
BACKGROUND The 3rd edition of the evidence-based clinical practice guidelines for gastroesophageal reflux disease (GERD) 2021 from the Japanese Society of Gastroenterology states that the treatment strategy for potassium-competitive acid blocker (PCAB)-refractory GERD remains unclear. Furthermore, even if GERD improves with the administration of an acid secretion inhibitor, it is feared that GERD may flare up after discontinuation of the drug, resulting in some cases in which patients are forced to take vonoprazan semipermanently (the so-called PCAB-dependent cases). From a global perspective, PCAB is not yet used in all countries and regions, and measures that can be taken now for cases in which a conventional proton pump inhibitor (PPI) is inadequately effective need to be devised. SUMMARY Endoscopic treatment for GERD may be effective in cases where conventional proton pump inhibitors are ineffective; however, there are insufficient long-term studies to corroborate this, and its cost effectiveness is unknown. Other treatment options for PCAB or PPI-refractory GERD include surgical procedures (Nissen and Toupet operations), which have a longer history than endoscopic treatment for GERD. However, their long-term results are not as good as those of acid secretion inhibitors, and they are not cost effective. Endoscopic treatment for GERD may fill gaps in inadequate surgical treatment. In April 2022, endoscopic anti-reflux mucosal resections (ARMS [anti-reflux mucosectomy] and ESD-G [endoscopic submucosal dissection for GERD]) were approved for reimbursement, making endoscopic treatment of GERD possible throughout Japan. KEY MESSAGES It is important to identify the background factors in cases in which endoscopic treatments are effective.

Abstract
BACKGROUND Proton-pump inhibitors (PPIs) are the mainstay of treatment in erosive esophagitis (EE). An alternative to PPIs in EE is Vonoprazan, a potassium competitive acid blocker. We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) comparing vonoprazan to lansoprazole. METHODS Multiple databases searched through November 2022. Meta-analysis was performed to assess endoscopic healing at two, four and eight weeks, including for patients with severe EE (Los Angeles C/D). Serious adverse events (SAE) leading to drug discontinuation were assessed. The quality of evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology. RESULTS Four RCTs with 2208 patients were included in the final analysis. Vonoprazan 20 mg once-daily was compared to lansoprazole 30 mg once-daily dosing. Among all patients, at two and eight weeks post-treatment, vonoprazan resulted in significantly higher rates of endoscopic healing as compared to lansoprazole, risk ratios (RR) 1.1, p<0.001 and RR 1.04, p=0.03. The same effect was not observed at four weeks, RR 1.03 (CI 0.99-1.06, I2=0%) following therapy. Among patients with severe EE, vonoprazan resulted in higher rates of endoscopic healing at two weeks, RR 1.3 (1.2-1.4, I2=47%), p=<0.001, at four weeks, RR 1.2 (1.1-1.3, I2=36%), p=<0.001 and at eight weeks post-treatment, RR 1.1 (CI 1.03-1.3, I2=79%), p=0.009. We found no significant difference in the overall pooled rate of SAE and pooled rate of adverse events leading to drug discontinuation. Finally, the overall certainty of evidence for our main summary estimates was rated as high (grade A). CONCLUSION Based on limited number of published non-inferiority RCTs, our analysis demonstrates that among patients with EE, vonoprazan 20 mg once-daily dosing achieves comparable and in those with severe EE, higher endoscopic healing rates as compared to lansoprazole 30 mg once-daily dosing. Both drugs have a comparable safety profile.

Abstract
Aim: 20 mg of vonoprazan (VPZ20) is recommended in most countries to treat erosive esophagitis (EE). Whether other doses of vonoprazan, such as 5 mg (VPZ5), 10 mg (VPZ10), 20 mg (VPZ20), and 40 mg (VPZ40) are more effective is unknown. Materials & methods: Three databases were electronically searched to identify studies published before November 2021. Network meta-analysis was performed using STATA 14.0. Results: VPZ20 and VPZ40 were comparable to PPI, VPZ5 and VPZ10 in 4- and 8-week healing rates, and this was also detected in patients with refractory EE. All regimens resulted in similar treatment-emergent adverse events (TEAEs). However, VPZ40 ranked first for healing rate and TEAEs; however, VPZ20 ranked worst for TEAEs. Conclusion: Different doses of VPZ are comparable in efficacy and safety, but VPZ40 may be best in both effectiveness and safety.

Abstract
Proton pump inhibitors (PPIs) are a mainstay treatment for acid peptic disorders such as gastroesophageal reflux disease (GERD). Although PPIs are considered first-line medications for acid suppression, they have notable limitations such as requiring acid-mediated activation, short half-life and duration of action, and metabolic variability. Fexuprazan is a newly developed potassium-competitive acid blocker (P-CAB), which inhibits acid generation and secretion in a competitive and reversible manner. Fexuprazan, like other P-CABs, has significantly different pharmacodynamic and pharmacokinetic properties than PPIs with potential advantages including rapid, robust, and durable acid suppression, lack of CYP2C19 metabolism, independence from food intake, and no requirement for activation into an active form. Completed clinical trials of fexuprazan have demonstrated comparable efficacy to PPIs for the healing of erosive esophagitis and relief of GERD-related esophageal symptoms without concerning safety signals. Ongoing clinical trials are evaluating fexuprazan for the prevention of NSAID-induced peptic ulcer disease, non-erosive GERD, and acute and chronic gastritis, as well as healing efficacy and maintenance of erosive esophagitis (EE). Fexuprazan is approved in South Korea for the treatment of EE and at the time of this writing is being considered for regulatory approval in several other countries. In this article, we summarize and discuss the pharmacology, efficacy, and safety of fexuprazan.

Abstract
INTRODUCTION Heartburn is a frequent symptom occurring in daily clinical practice and is mainly associated with gastroesophageal reflux disease (GERD). However, it can be stimulated by various factors and diseases other than GERD can present with heartburn. Therefore, physicians must be very careful in distinguishing GERD from non-GERD conditions in their patients, particularly when heartburn is refractory to anti-reflux medications. AREAS COVERED The aim of this narrative review was to analyze the medical literature regarding the prevalence of heartburn and the various clinical disorders which can be present with this symptom. The type of medications usually adopted for treating heartburn and their grade of safety have been reviewed using an extensive computerized (Medline/PubMed) search with particular focus on the last 20 years. EXPERT OPINION Many drugs can be used for relieving heartburn in patients with GERD, although PPIs are the pharmacological agents with the greatest efficacy. However, it must be highlighted that many non-GERD conditions may present clinically with this symptom whose intensity does not differ between GERD and functional esophageal disorders, which represent about 50% of all patients with suspected GERD. It is very important to identify these functional conditions because their treatment differs completely from that of GERD.

Abstract
BACKGROUND VISION is a randomised, phase 4, open-label, parallel-group, multicentre study conducted in 33 centres in Japan. The aim of this study was to assess the long-term safety of vonoprazan for maintenance treatment of healed erosive oesophagitis versus lansoprazole. METHODS Patients with endoscopically diagnosed erosive oesophagitis were randomised 2:1 to once-daily vonoprazan 20 mg or lansoprazole 30 mg, for a 4- to 8-week healing phase. Patients with endoscopically confirmed healing entered a 260-week maintenance phase with a once-daily starting dose of vonoprazan 10 mg or lansoprazole 15 mg. Primary endpoint was change in gastric mucosal histopathology. RESULTS Of 208 patients (vonoprazan, n = 139; lansoprazole, n = 69) entering the healing phase, 202 entered the maintenance phase (vonoprazan, n = 135; lansoprazole, n = 67). At 3 years, 109 vonoprazan-treated and 58 lansoprazole-treated patients remained on treatment. Histopathological evaluation of gastric mucosa showed that hyperplasia of parietal, foveolar and G cells was more common with vonoprazan than lansoprazole at week 156 of the maintenance phase. There was no marked increase in the occurrence of parietal, foveolar and G cell hyperplasia among patients in the vonoprazan group from week 48 to week 156. Histopathological evaluation of the gastric mucosa also showed no neoplastic changes in either group. No new safety issues were identified. CONCLUSIONS In this interim analysis of VISION, no new safety concerns were identified in Japanese patients with healed erosive oesophagitis receiving vonoprazan or lansoprazole as maintenance treatment for 3 years.

Abstract
GOALS The aim was to examine actual health care cost in patients with gastroesophageal reflux disease (GERD) who were initiated on proton pump inhibitor (PPI) or potassium-competitive acid blocker (P-CAB) as first-line therapy in Japanese real-world clinical settings. BACKGROUND To date, cost-utility evaluation of acid-suppressants treatment in Japan has only been conducted by model analysis. STUDY A cost utilization analysis was performed using a Japanese nationwide hospital-based claim database by extracting patients with GERD initiated on either PPI or P-CAB (242,102 pairs) and esomeprazole (EPZ) or P-CAB (241,825 pairs). Health care costs were compared in each comparison cohort with propensity-score matched pairs. The switching rates of initial acid-suppressants were also examined. RESULTS Baseline characteristics were well-balanced after matching. The 3-year mean cumulative GERD-related and hospitalization costs per patient were ¥142,620 and ¥122,444 in PPI-first and P-CAB-first treatment groups, and ¥105,263 and ¥121,958 in EPZ-first and P-CAB-first treatment groups, respectively. Most hospitalization costs were non-GERD related in all the groups. The switching rates of PPI to P-CAB and P-CAB to PPI in 12 months were 7.5% and 20.2%, respectively. CONCLUSIONS In this propensity-score matched analysis, health care cost was higher in patients with GERD initiated on PPI than in those initiated on P-CAB mainly owing to non-GERD-related hospitalization cost, whereas it was lower in those initiated on EPZ than in those initiated on P-CAB. When considering health care costs except hospitalization costs, PPI-first treatment was less expensive than P-CAB-first treatment. Low switching rate from PPI to P-CAB in the real-world practice may partially explain the discrepancy.

Abstract
The upper gastrointestinal (GI) tract is frequently involved in systemic sclerosis (SSc) and may impact quality of life, physical function and survival. Although we are currently very proactive in terms of screening for heart and lung involvement, patients with SSc are not routinely screened for GI involvement. This review details the available investigations for common upper GI symptoms in SSc, including dysphagia, reflux and bloating and provides advice as to how to integrate these investigations into current clinical care.

Abstract
BACKGROUND & AIMS For decades, proton pump inhibitors (PPIs) have been the mainstay of treatment for erosive esophagitis. The potassium-competitive acid blocker vonoprazan provides more potent acid inhibition than PPIs, but data on its efficacy for erosive esophagitis are limited. METHODS Adults with erosive esophagitis were randomized to once-daily vonoprazan, 20 mg, or lansoprazole, 30 mg, for up to 8 weeks. Patients with healing were rerandomized to once-daily vonoprazan, 10 mg, vonoprazan, 20 mg, or lansoprazole, 15 mg, for 24 weeks. Primary end points, percentage with healing by week 8 endoscopy, and maintenance of healing at week 24 endoscopy, were assessed in noninferiority comparisons (noninferiority margins, 10%), with superiority analyses prespecified if noninferiority was demonstrated. Analyses of primary and secondary end points were performed using fixed-sequence testing procedures. RESULTS Among 1024 patients in the healing phase, vonoprazan was noninferior to lansoprazole in the primary analysis and superior on the exploratory analysis of healing (92.9 vs 84.6%; difference, 8.3%; 95% confidence interval [CI], 4.5%-12.2%). Secondary analyses showed vonoprazan was noninferior in heartburn-free days (difference, 2.7%; 95% CI, -1.6% to 7.0%), and superior in healing Los Angeles Classification Grade C/D esophagitis at week 2 (difference, 17.6%; 95% CI, 7.4%-27.4%). Among 878 patients in the maintenance phase, vonoprazan was noninferior to lansoprazole in the primary analysis and superior on the secondary analysis of maintenance of healing (20 mg vs lansoprazole: difference, 8.7%; 95% CI, 1.8%-15.5%; 10 mg vs lansoprazole: difference, 7.2%; 95% CI, 0.2%-14.1%) and secondary analysis of maintenance of healing Grade C/D esophagitis (20 mg vs lansoprazole: difference, 15.7%; 95% CI, 2.5%-28.4%; 10 mg vs lansoprazole: difference, 13.3%; 95% CI, 0.02%-26.1%). CONCLUSIONS Vonoprazan was noninferior and superior to the PPI lansoprazole in healing and maintenance of healing of erosive esophagitis. This benefit was seen predominantly in more severe erosive esophagitis. (ClinicalTrials.gov: NCT04124926).

Abstract
Background Vonoprazan, a novel acid-suppressive drug, is non-inferior to proton pump inhibitors (PPIs) for the management of gastric acid-related diseases. However, the safety of vonoprazan has not been systematically evaluated yet. Objectives To elucidate the incidence and type of adverse events (AEs) in patients taking vonoprazan. Design Systematic review and meta-analysis. Data sources and methods PubMed, EMBASE, and Cochrane Library databases were searched for all studies reporting the safety of vonoprazan. The incidences of any AEs, drug-related AEs, serious AEs, AEs leading to drug discontinuation, and common AEs were pooled. Odds ratios (ORs) were calculated to compare the incidence of AEs between patients taking vonoprazan and PPIs. Results Seventy-seven studies were included. The pooled incidences of any AEs, drug-related AEs, serious AEs, and AEs leading to drug discontinuation were 20, 7, 1, and 1%, respectively. The incidences of any AEs (OR = 0.96, p = 0.66), drug-related AEs (OR = 1.10, p = 0.44), serious AEs (OR = 1.14, p = 0.36), and AEs leading to drug discontinuation (OR = 1.09, p = 0.55) were not significantly different between patients taking vonoprazan and PPIs. In subgroup analyses, patients with peptic ulcer disease (PUD) had higher incidences of any AEs, serious AEs, and AEs leading to drug discontinuation than those with gastroesophageal reflux disease (GERD), Helicobacter pylori (H. pylori) infection, and artificial ulcer after gastric endoscopic submucosal dissection (ESD), but patients with H. pylori infection had a higher incidence of drug-related AEs than those with PUD, GERD, and artificial ulcer after gastric ESD. The incidence of AEs was higher in patients taking long-term use of vonoprazan than those taking short-term use of vonoprazan. Conclusion Vonoprazan is well tolerated and shows similar safety compared to PPIs. The safety of vonoprazan may be primarily influenced by its indications and duration.

Abstract
Proton pump inhibitors (PPIs) have several limitations to their efficacy including insufficient acid suppression, slow onset of action, and variable efficacy among patients due to CYP2C19 metabolism. Potassium-competitive acid blockers inhibit H+-K+-ATPase in a reversible and K+-competitive manner, are novel acid suppressive drugs with rapid onset of action, meal independence, and prolonged control of intragastric acidity compared to PPIs. Potassium-competitive acid blockers exhibited non-inferior therapeutic efficacies on reflux esophagitis, gastric ulcers, and Helicobacter pylori eradication. The review is focused on the unmet needs across the acid-related diseases and recent updates on clinical studies using vonoprazan and tegoprazan.

Abstract
BACKGROUND Long-term acid suppression during vonoprazan therapy causes hypergastrinemia which may induce gastric mucosal changes such as fundic gland and hyperplastic polyps. The aim of this study is to clarify the long-term changes in serum gastrin levels and risk factors for hypergastrinemia. METHODS From July 2016 to April 2020, 48 patients receiving vonoprazan 10 mg once daily for more than one year were reviewed. Serum gastrin level was evaluated by radioimmunoassay in a fasting condition (reference range 37-172 pg/ml). RESULTS The baseline median gastrin level was 100 (range, 54-415) pg/ml. The gastrin level over 4 years was 700-1200 pg/ml, which plateaued at 1.5 years. Multivariate analysis revealed factors associated with gastrin levels 12 months after starting vonoprazan and identified severe gastric atrophy as a significant positive risk factor (p = .046). The gastrin level over 4 years in patients with severe gastric atrophy and no atrophy was approximately 900-1500 and 500-1000 pg/ml, respectively. Female gender was also identified as a positive factor, although it was not statistically significant (p = .087). The gastrin level over 4 years in females was approximately 900-1300 pg/ml, greater than in males (500-900 pg/ml). CONCLUSION A continued increase in gastrin levels was not found during long-term vonoprazan therapy. Severe gastric atrophy is a significant risk factor for hypergastrinemia.

A comparison of efficacy and safety of potassium-competitive acid blocker and proton pump inhibitor in gastric acid-related diseases: A systematic review and meta-analysis. J Gastroenterol Hepatol 2022; 37:2217-2228. [PMID: 36181401 PMCID: PMC10092067 DOI: 10.1111/jgh.16017] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2022] [Revised: 09/09/2022] [Accepted: 09/26/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIM Potassium-competitive acid blocker (PCAB) is a recent alternative to proton pump inhibitor (PPI) for potent acid suppression. The current systematic review and meta-analysis aimed to compare the efficacy and safety of PCAB versus PPI in treating gastric acid-related diseases. METHODS We searched up to June 5, 2022, for randomized controlled trials of gastric acid-related diseases that included erosive esophagitis, symptomatic gastroesophageal reflux disease (GERD), peptic ulcers, and Helicobacter pylori infection. The pooled risk ratio (RR) was evaluated for the efficacy outcome and treatment-emergent adverse events (TEAEs) as the safety outcome. Sensitivity analyses were performed to test the robustness of the study findings. RESULTS Of the 710 screened studies, 19 studies including 7023 participants were analyzed. The RRs for the healing of erosive esophagitis with Vonoprazan versus PPI were 1.09 (95% confidence interval [CI] 1.03-1.14), 1.03 (95% CI 1.00-1.07), and 1.02 (95% CI 1.00-1.05) in Weeks 2, 4, and 8, respectively. There were no differences in the improvement of GERD symptoms and healing of gastric and duodenal ulcers between PCAB and PPI. The pooled eradication rates of H. pylori were significantly higher in Vonoprazan versus PPI first-line treatment (RR 1.13; 95% CI 1.04-1.22). The overall RR of TEAEs with Vonoprazan versus PPI was 1.08 (95% CI 0.89-1.31). Overall, the risk of bias was low to some concerns. Furthermore, sensitivity analyses confirmed the robustness of the study's conclusion. CONCLUSION Vonoprazan is superior to PPI in first-line H. pylori eradication and erosive esophagitis but non-inferior in other gastric acid-related diseases. Likewise, short-term safety is comparable in both treatment groups.

Abstract
Potassium-competitive acid blockers (PCABs) such as vonoprazan represent a novel class of acid suppressants that show tremendous promise to enhance care of acid peptic disorders. PCAB characteristics distinct from those of proton pump inhibitors-such as acid stability with dosing independent of food consumption, rapid onset of action, less variability with CYP2C19 polymorphisms, and extended half-lives-may add value in clinical practice. With recently reported data beyond Asian populations and expanding regulatory approval of PCABs, clinicians should be aware of these medications and their potential roles in the management of acid peptic disorders. This article provides an up-to-date summary of the evidence around PCABs for the treatment of gastroesophageal reflux disease (especially erosive esophagitis healing and maintenance), eosinophilic esophagitis, Helicobacter pylori infection, and peptic ulcer healing and secondary prophylaxis.

Abstract
BACKGROUND Fexuprazan, a novel potassium-competitive acid blocker, reversibly suppresses the K+/H+-ATPase enzyme in proton pumps within gastric parietal cells. Fexuprazan’s suppression of gastric acid was maintained in healthy individuals for 24 h in a dose-dependent manner.
AIM To compare fexuprazan to esomeprazole and establish its efficacy and safety in patients with erosive esophagitis (EE).
METHODS Korean adult patients with endoscopically confirmed EE were randomized 1:1 to receive fexuprazan 40 mg or esomeprazole 40 mg once daily for eight weeks. The primary endpoint was the proportion of patients with healed EE confirmed by endoscopy at week 8. The secondary endpoints included the healing rate of EE at week 4, symptom response, and quality of life assessment. Safety profiles and serum gastrin levels were compared between the groups.
RESULTS Of the 263 randomized, 218 completed the study per protocol (fexuprazan 40 mg, n = 107; esomeprazole 40 mg, n = 111). Fexuprazan was non-inferior to esomeprazole regarding the healing rate at week 8 [99.1% (106/107) vs 99.1% (110/111)]. There were no between-group differences in the EE healing rate at week 4 [90.3% (93/103) vs 88.5% (92/104)], symptom responses, and quality of life assessments. Additionally, serum gastrin levels at weeks 4 and 8 and drug-related side effects did not significantly differ between the groups.
CONCLUSION Fexuprazan 40 mg is non-inferior to esomeprazole 40 mg in EE healing at week 8. We suggest that fexuprazan is an alternative promising treatment option to PPIs for patients with EE.

Abstract
BACKGROUND Proton-pump inhibitors (PPIs) and vonoprazan are recommended as first-line therapies for erosive esophagitis (EE). However, it is uncertain how the magnitude of efficacy and safety of first-line therapy, the choice of individual PPIs or vonoprazan in the treatment of EE remains controversial. This study aimed to evaluate the efficacy and safety of vonoprazan and PPIs in healing esophageal mucosal injury in patients with EE. METHODS Relevant databases were searched to collect randomized controlled trials of proton pump inhibitors and vonoprazan in the treatment of reflux esophagitis up to December 2021. Studies on standard-dose PPIs or vonoprazan that were published in Chinese or English and assessed healing effects in EE were included in the analysis. Stata16.0 was used to conduct a network Meta-analysis to evaluate the efficacy and safety of the treatment. RESULTS A total of 41 literatures were included with 11,592 enrolled patients. For the endoscopic cure rate, all the PPIs and vonoprazan significantly improve compared to Placebo; Based on the surface under the cumulative ranking curve, Ilaprazole ranked first, followed by esomeprazole, vonoprazan, pantoprazole, lansoprazole, omeprazole, rabeprazole and placebo therapy ranked the last. For the rate of adverse events, there was no significant difference among all the PPIs, vonoprazan, and placebo. CONCLUSIONS Ilaprazole, esomeprazole and vonoprazan have more advantages in mucosal erosion healing, there was no significant difference in the comparative safety among all interventions.

Abstract
PURPOSE OF REVIEW The majority of patients with systemic sclerosis (SSc) will experience involvement of their gastrointestinal over the course of their disease. Despite the high prevalence of gastrointestinal involvement in SSc, the strategies pertaining to the assessment and treatment for this clinical dimension of SSc have historically been limited. However, the present review highlights recent research contributions that enhance our understanding of SSc-GI patient subsets and provides updates on pathogenic mechanisms of disease, assessment and symptom-directed management. RECENT FINDINGS In the past few years, several studies have identified risk factors for more severe gastrointestinal disease in SSc and have provided insight to optimize diagnosis and management of SSc-GI symptoms. This article also provides a review of currently available investigations and therapies for individual SSc-GI disease manifestations and reflects on actively evolving areas of research, including our understanding the role of the gut microbiome in SSc. SUMMARY Here, we provide important updates pertaining to the risk stratification, assessment, diagnosis and management of SSc patients with gastrointestinal symptoms. These findings provide opportunities to enhance patient care and highlight exciting opportunities for future research.

Abstract
Acid suppression is the primary therapy for erosive esophagitis (EE). Although proton pump inhibitors (PPIs) are considered as the first-line medication for EE, 10-20% of patients with Los Angeles C and D grade EE do not gain complete mucosal healing and symptom control despite 8-week double-dose PPI treatment. Vonoprazan is a novel potassium-competitive acid blocker (P-CAB), which blocks the H+, K+-adenosine triphosphatase enzymes in a K+-competitive and reversible manner. Vonoprazan exhibits different pharmacological and pharmacokinetic profiles from conventional PPIs, and has a rapid, potent and sustained acid inhibitory effect. In this review, we summarized and discussed current evidence regarding the role of vonoprazan in terms of mucosal healing, maintaining remission and symptom relief for the management of EE, including the initial and maintenance treatment of EE, as well as for PPI-resistant EE patients. Safety concerns and cost-effectiveness analysis of vonoprazan were also mentioned in the article. As a potent and well-tolerated acid blocker, vonoprazan has the potential to become a novel option for the management of EE.

Abstract
BACKGROUND The cytochrome P450 (CYP) 2C19 genotype has a profound effect on the efficacy of lansoprazole, with less of an influence on vonoprazan. Both are first-choice drugs for the treatment of reflux esophagitis in China. OBJECTIVE We aimed to estimate the cost-effectiveness of acid-suppressive treatments in Chinese patients with reflux esophagitis over 1 year from the societal perspective. METHODS We developed a decision-based Markov model with a 4-week cycle to simulate the economic benefits and quality-adjusted life-years between different treatment strategies for patients with reflux esophagitis: universal lansoprazole, universal vonoprazan, and CYP2C19 genotype-guided strategies. The primary outcome was the incremental cost-effectiveness ratio. Data sources were the published literature, clinical trials, documents, and local charges. We used sensitivity analyses to detect the robustness of the findings and explored subgroup analyses and scenario analyses to make further evaluations. RESULTS Compared to lansoprazole, vonoprazan and the CYP2C19 genotype-guided strategy were not preferable for Chinese patients with reflux esophagitis, with an incremental cost-effectiveness ratio of 222,387.1316 yuan/quality-adjusted life-year and 349,627.5000 yuan/quality-adjusted life-year, respectively. Sensitivity analyses showed the impact factors were the utility scores and the expenditures for the maintenance stage with lansoprazole and vonoprazan. When the willingness-to-pay threshold was 215,484 yuan/quality-adjusted life-year, 46.20% of the reflux esophagitis population was willing to pay for vonoprazan, compared with 8.30% for the CYP2C19 genotype-guided strategies. Vonoprazan and the CYP2C19 genotype-guided strategy were cost effective in the severe reflux esophagitis population, and in the reduction of the price of vonoprazan. CONCLUSIONS The health economic evaluations revealed that for Chinese patients with reflux esophagitis, vonoprazan and the CYP2C19 genotype-guided strategy were not cost-effective regimens compared with lansoprazole. However, we found that in certain conditions like a reduction in the price of vonoprazan and in patients with severe reflux esophagitis these could be cost-effective.

Abstract
Proton pump inhibitors (PPIs), the most commonly used antisecretory medi-cations in the management of reflux illness, virtually eliminate elective surgery for ulcer disease, and relegate anti-reflux surgery to patients with gastroesophageal reflux disease (GERD) who are inadequately managed by medical therapy. However, PPI medications still leave some therapeutic demands of GERD unmet. Furthermore, up to 40%-55% of daily PPI users have chronic symptoms, due to PPI refractoriness. Potassium-competitive acid blockers (P-CABs) transcend many of the problems and limits of PPIs, delivering quick, powerful, and extended acid suppression and allowing for treatment of numerous unmet needs. Recently, it has become clear that compromised mucosal integrity plays a role in the etiology of GERD. As a result, esophageal mucosal protection has emerged as a novel and potential treatment approach. An increasing body of research demonstrates that when P-CABs are used as primary drugs or add-on drugs (to regular treatment), they provide a considerable extra benefit, particularly in alleviating symptoms that do not respond to PPI therapy.

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
BACKGROUND Keverprazan is a novel potassium-competitive acid blocker (P-CAB) with a strong acid-suppressive capacity that may provide clinical benefit in acid-related diseases. AIMS This study aimed to explore the non-inferior efficacy and safety of keverprazan to lansoprazole in treating erosive oesophagitis (EO). METHODS This was a phase III, randomised, double-blind multicentre study. Patients were randomised to receive keverprazan 20 mg once daily or lansoprazole 30 mg once daily for 4-8 weeks. EO healing rates and adverse events (AEs) were compared between the keverprazan group and the lansoprazole group. RESULTS A total of 238 patients comprised the full analysis set (FAS) while 221 patients comprised the per-protocol set (PPS). For FAS analysis, the EO healing rates at week 8 were 95.8% (114/119) and 89.9% (107/119) for keverprazan and lansoprazole respectively. For PPS analysis, the EO healing rates at week 8 were 99.1% (110/111) and 92.7% (102/110) for keverprazan and lansoprazole respectively. Non-inferiority of keverprazan compared with lansoprazole according to EO healing rates at 8 weeks was demonstrated in both FAS (difference: 5.8% [95% CI: -0.6% to 12.3%]; p = 0.081) and PPS (difference: 6.1% [95% CI: 1.1%-11.2%]; p = 0.018) analysis. Drug-related AEs were reported in 34.5% (41/119) patients of the keverprazan group and 25.2% (30/119) patients of the lansoprazole group with no significant difference (p = 0.156). No severe AE happened in the keverprazan group. CONCLUSIONS This study demonstrated the non-inferior efficacy of keverprazan to lansoprazole in treating EO. The incidences of drug-related AEs were comparable between keverprazan and lansoprazole.

Abstract
Gastroesophageal reflux disease (GERD) is very common and defined as troublesome symptoms owing to excessive acid reflux. The spectrum of GERD is broad, including not only erosive esophagitis and Barrett's esophagus but also nonerosive reflux disease (NERD), reflux hypersensitivity, and functional heartburn. Patients with reflux symptoms despite normal endoscopy remain common clinical presentation, can be heterogeneous overlapping with functional gastrointestinal disorders. Ambulatory esophageal pH monitoring with and without impedance helps the diagnosis of NERD. Metrics such as baseline impedance and postreflux swallow induced peristaltic wave enhance diagnostic accuracy in patients with inconclusive diagnoses. The major treatment of all manifestations of GERD is acid suppression with proton pump inhibitors, while other therapies, such as reflux-reducing agents and adjunctive medications, can be individualized where the response to traditional management is incomplete. GERD patients often need long-term treatment due to frequent relapses. Anti-reflux surgery can be effective too. Endoscopic therapies have some promising results, but long-term outcomes remain to be determined.

Abstract
INTRODUCTION Patients with acid-related disorders (ARDs) of the upper digestive tract remain highly prevalent and need to be continuously investigated to improve their management. AREAS COVERED This review provides a summary of the most recent advancements in the treatment of ARDs with particular focus on the new drugs available to overcome the unmet needs of traditional therapies. EXPERT OPINION Proton pump inhibitors remain the best therapy in treating ARDs, but a consistent proportion of these patients continues to present mucosal lesions or to experience symptoms despite treatment. These cases pertain mainly to the most severe forms of erosive esophagitis or to non-erosive reflux disease. Also, the increasing rate of patients with H. pylori infection not responding to eradication therapy represents a difficult clinical condition. The recent advent of a new class of antisecretory drugs, such as the potassium competitive acid blockers and, among them the most studied vonoprazan, which are characterized by a better pharmacological profile than PPIs (rapid onset of action, longer lasting acid suppression, control of nocturnal acidity), has the potential to overcome the above-mentioned unmet needs. More research should be done to assess their efficacy in Western populations and their safety in patients treated in the long term.

Abstract
Gastroesophageal reflux disease (GERD) is common worldwide and poses a huge challenge to health. Consensuses and guidelines on the diagnosis and management of GERD in China and the USA have recently been updated. The divergence between these guidelines indicates the differences in the conception of this disease by experts in different countries, and is influenced by available medications and interventional procedures. Prompt endoscopy has been advocated in China due to a high prevalence of upper gastrointestinal (GI) cancer, while endoscopy has been reserved for those who are at a risk of malignancy or who are reisitant to proton pump inhibitors (PPIs) in the USA. A potassium channel acid-blocker is widely used in Asian countries and has proven efficacy. Moreover, it has been recommended, together with PPIs, as a primary therapy for GERD in China; while PPI alone is recommended as a first-line treatment in the USA. Although more prokinetics are available in China than in the USA and can alleviate GERD symptoms when combined with PPI, the choice of prokinetics is limited in the USA, leading to completely opposite attitudes to prokinetics in the two countries. Novel anti-reflux procedures have been introduced in both countries. Transoral incisionless fundoplication (TIF) is recommended as an endoscopic anti-reflux procedure, and magnetic sphincter augmentation (MSA) is recognized as equivocal to conventional laparoscopic fundoplication in the USA. However, radiofrequency ablation is more popular in China, and clinical trials on TIF and MSA are not complete, which results in diverse opinions about suitable anti-reflux procedures in China. A comparison of the guidelines may therefore shed light on the multiple dimensions of GERD and thus deepen our understanding of the disease.
