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.

ARQUIVOS DE GASTROENTEROLOGIA 2024; 61:e23154. [PMID: 38511797 DOI: 10.1590/s0004-2803.24612023-154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Accepted: 11/29/2023] [Indexed: 03/22/2024]
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
Gastroesophageal reflux disease (GERD) is one of the most prevalent and bothersome functional gastrointestinal disorders worldwide, including in Thailand. After a decade of the first Thailand GERD guideline, physician and gastroenterologist encountered substantially increase of patients with GERD. Many of them are complicated case and refractory to standard treatment. Concurrently, the evolution of clinical characteristics as well as the progression of investigations and treatment have developed and changed tremendously. As a member of Association of Southeast Asian Nations, which are developing countries, we considered that the counterbalance between advancement and sufficient economy is essential in taking care of patients with GERD. We gather physicians from university hospitals, as well as internist and general practitioners who served in rural area, to make a consensus in this updated version of GERD guideline focusing in medical management of GERD. This clinical practice guideline was constructed adhering with standard procedure. We categorized the guideline in to four parts including definition, investigation, treatment, and long-term follow up. We anticipate that this guideline would improve physicians' proficiency and help direct readers to choose investigations and treatments in patients with GERD wisely. Moreover, we wish that this guideline would be applicable in countries with limited resources as well.

J Neurogastroenterol Motil 2022; 28:5-14. [PMID: 34980685 PMCID: PMC8748841 DOI: 10.5056/jnm21095] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 07/30/2021] [Accepted: 08/10/2021] [Indexed: 12/13/2022] Open
Abstract
Background/Aims Long-term maintenance treatment of gastroesophageal reflux disease (GERD) is commonly used to prevent relapse of reflux symptoms; however, due to concerns about safety of long-term proton pump inhibitors (PPI) use, on-demand therapy is recommended as a long-term treatment modality. We compared the efficacy of on-demand and continuous PPI therapy for maintenance treatment of patients with GERD using meta-analysis. Methods Core electronic databases were searched for randomized controlled trials comparing on-demand and continuous therapy in GERD patients. The primary outcome was treatment failure of maintenance therapy, and the secondary outcomes included symptomatic relief, patient satisfaction, and amount of PPI use. Results Overall, 11 studies were selected in the systematic review and meta-analysis. Compared with continuous PPI therapy, on-demand therapy showed similar outcomes for treatment failure (risk ratio, 1.26; 95% confidence interval [CI], 0.76-2.07), particularly in the non-erosive esophageal reflux disease and mild erosive reflux disease group (risk ratio, 1.48; 95% CI, 0.39-5.63). In studies including severe esophagitis patients, continuous PPI maintenance treatment was more effective (β, 0.127 [95% CI, 0.066-0.188]; P < 0.001). Severity of esophagitis was associated with higher efficacies of continuous maintenance therapy. The amount of daily PPI use was about half in the on-demand group compared to the continuous group (risk difference −0.52; 95% CI, −0.62-−0.42). Conclusions On-demand PPI therapy shows comparable efficacy to the continuous maintenance treatment in the non-erosive esophageal reflux disease and mild erosive reflux disease group, and can remarkably reduce the amount of PPI use. Therefore, on-demand therapy may be preferentially recommended in the maintenance treatment of GERD unaccompanied by severe esophagitis.

Abstract
Gastroesophageal reflux disease (GERD) is a condition in which gastric contents regurgitate into the esophagus or beyond, resulting in either troublesome symptoms or complications. GERD is heterogeneous in terms of varied manifestations, test findings, and treatment responsiveness. GERD diagnosis can be established with symptomatology, pathology, or physiology. Recently the Lyon consensus defined the “proven GERD” with concrete evidence for reflux, including advanced grade erosive esophagitis (Los Angeles classification grades C and or D esophagitis), long-segment Barrett’s mucosa or peptic strictures on endoscopy or distal esophageal acid exposure time > 6% on 24-hour ambulatory pH-impedance monitoring. However, some Asian researchers have different opinions on whether the same standards should be applied to the Asian population. The prevalence of GERD is increasing in Asia. The present evidence-based guidelines were developed using a systematic review and meta-analysis approach. In GERD with typical symptoms, a proton pump inhibitor test can be recommended as a sensitive, cost-effective, and practical test for GERD diagnosis. Based on a meta-analysis of 19 estimated acid-exposure time values in Asians, the reference range upper limit for esophageal acid exposure time was 3.2% (95% confidence interval, 2.7-3.9%) in the Asian countries. Esophageal manometry and novel impedance measurements, including mucosal impedance and a post-reflux swallow-induced peristaltic wave, are promising in discrimination of GERD among different reflux phenotypes, thus increasing its diagnostic yield. We also propose a long-term strategy of evidence-based GERD treatment with proton pump inhibitors and other drugs.

Abstract
Gastroesophageal Reflux Disease (GERD) is characterized by acid and bile reflux in the distal oesophagus, and this may cause the development of reflux esophagitis and Barrett's oesophagus (BE). The natural histological course of untreated BE is non-dysplastic or benign BE (ND), then lowgrade (LGD) and High-Grade Dysplastic (HGD) BE, with the expected increase in malignancy transfer to oesophagal adenocarcinoma (EAC). The gold standard for BE diagnostics involves high-resolution white-light endoscopy, followed by uniform endoscopy findings description (Prague classification) with biopsy performance according to Seattle protocol. The medical treatment of GERD and BE includes the use of proton pump inhibitors (PPIs) regarding symptoms control. It is noteworthy that long-term use of PPIs increases gastrin level, which can contribute to transfer from BE to EAC, as a result of its effects on the proliferation of BE epithelium. Endoscopy treatment includes a wide range of resection and ablative techniques, such as radio-frequency ablation (RFA), often concomitantly used in everyday endoscopy practice (multimodal therapy). RFA promotes mucosal necrosis of treated oesophagal region via high-frequency energy. Laparoscopic surgery, partial or total fundoplication, is reserved for PPIs and endoscopy indolent patients or in those with progressive disease. This review aims to explain distinct effects of PPIs and RFA modalities, illuminate certain aspects of molecular mechanisms involved, as well as the effects of their concomitant use regarding the treatment of BE and prevention of its transfer to EAC.

Abstract
BACKGROUND AND AIMS No consensus has been established regarding optimal long-term maintenance therapy in symptomatic gastroesophageal reflux disease (GERD). The aim of this study was to compare the efficacies of on-demand and continuous therapy with esomeprazole as maintenance treatments for GERD. METHODS Patients with upper gastrointestinal (GI) endoscopy-proven GERD who received initial proton pump inhibitor (PPI) therapy for 8 weeks were randomized to an on-demand group (esomeprazole 40 mg) or a continuous group (esomeprazole 20 mg). Intensities and frequencies of heartburn and acid regurgitation were assessed using a 6-point Likert scale (0 = no symptoms; 5 = very severe symptoms) and a 6-point frequency scale (0 = none; 5 = symptoms for > 5 days per week) at baseline (start of maintenance treatment) and after 12 weeks of treatment. Alleviation of symptoms was quantified using percentages of patients with a Likert scale or frequency scale of 0 or 1. RESULTS Of the 88 patients enrolled, 8 patients were excluded due to follow-up loss in early period of this study, and finally, 39 in the on-demand group and 41 in the continuous group were analyzed. No significant intergroup difference was found between Likert scale or frequency scale of heartburn or regurgitation at baseline. Percentages of symptom alleviations in the on-demand and continuous groups for intensity of heartburn were 56.4%/48.8% at baseline (P = .523) and 82.1%/87.8% at 12 weeks (P = .471), for frequency of heartburn were 61.5%/46.3% at baseline (P = .173) and 76.9%/87.8% at 12 weeks (P = .200), for intensity of regurgitation was 53.8%/43.9% at baseline (P = .374) and 82.1%/87.8% at 12 weeks (P = .471), and for frequency of regurgitation was 61.5%/56.1% at the baseline (P = .621) and 82.1%/82.9% at 12 weeks (P = .918), respectively. Furthermore, no significant intergroup difference was found for convenience of medication or subjective satisfaction. CONCLUSIONS Intensities and frequencies of heartburn and regurgitation responded well to maintenance treatment in patients in the on-demand and continuous groups. On-demand therapy with esomeprazole 40 mg appears to be sufficient for maintenance treatment in GERD patients.

Abstract
BACKGROUND The study aimed to evaluate the efficacy of on-demand therapy using 20-mg vonoprazan for mild reflux esophagitis (RE). METHODS On-demand therapy by taking one 20-mg tablet of vonoprazan only when reflux symptoms occurred was performed for 24 weeks using 30 patients with mild RE who were receiving maintenance therapy with proton pomp inhibitors (PPIs). The presence or absence of RE, degree of overall satisfaction with the treatment, score of symptoms, and fasting gastrin level before breakfast were examined before and after on-demand therapy. The number of tablets taken during the 24-week period was also noted. RESULTS One of the 30 patients dropped out of on-demand therapy 1 week after its initiation. Remission was maintained in 25 (86.2%) of the 29 patients (all 10 [100%] Los Angeles classification grade A patients and 15 (78.9%) of the 19 grade B patients). However, 4 grade B patients exhibited grade B relapse. There were no differences in the degree of overall satisfaction, score of symptoms or the gastrin level between PPI and on-demand therapies. The number of vonoprazan tablets taken during the observation period was 33 tablets (median)/24 weeks. CONCLUSION On-demand therapy using 20-mg vonoprazan tablets is an effective alternative maintenance therapy for mild RE.

On-Demand Therapy with Proton Pump Inhibitors for Maintenance Treatment of Nonerosive Reflux Disease or Mild Erosive Esophagitis: A Systematic Review and Meta-Analysis. Gastroenterol Res Pract 2018; 2018:6417526. [PMID: 30158966 PMCID: PMC6109549 DOI: 10.1155/2018/6417526] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 06/30/2018] [Accepted: 07/10/2018] [Indexed: 12/14/2022] Open
Abstract
Background Proton pump inhibitors (PPIs) are widely used for the long-term management of gastroesophageal reflux disease (GERD). However, concerns about the cost and/or inconvenience of continuous maintenance PPI treatment have led to the evaluation of various alternative approaches. Aim To assess the effectiveness of on-demand PPI therapy in the maintenance treatment of nonerosive reflux disease (NERD) or mild erosive esophagitis (EE). Methods We searched MEDLINE, EMBASE, Web of Science, and Cochrane Library from inception until October 2, 2017, for randomized controlled trials (RCTs) comparing on-demand PPI versus placebo or daily PPI in the management of NERD or mild EE (Savary-Miller grade 1). Discontinuation of therapy during the trial was used as a surrogate for patient dissatisfaction and failure of symptomatic control. We calculated pooled odds ratios (OR) to evaluate the efficacy of on-demand PPI treatment. Separate analyses were conducted for studies comparing on-demand PPI with daily PPI and with placebo. Subgroup analysis was done based on NERD studies alone and on studies of both NERD and mild EE. These were analyzed using a random effects model. Results We included 10 RCTs with 4574 patients. On-demand PPI was superior to daily PPI (pooled OR = 0.50; 95% confidence interval (CI) = 0.35, 0.72). On subgroup analysis in NERD patients only, pooled OR was 0.44 (0.29, 0.66). In studies including patients with NERD and mild EE, pooled OR was 0.76 (0.36, 1.60). For studies comparing on-demand PPI with placebo, pooled OR was 0.21 (0.15, 0.29); subgroup analyses of studies evaluating NERD only and studies conducted in NERD and mild EE showed similar results (pooled OR was 0.22 (0.13, 0.36) and 0.18 (0.11, 0.31), resp.). Conclusions On-demand PPI treatment is effective for many patients with NERD or mild EE. Although not FDA-approved, it may be adequate for those patients whose symptoms are controlled to their satisfaction.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are a class of medications that reduce acid secretion and are used for treating many conditions such as gastroesophageal reflux disease (GERD), dyspepsia, reflux esophagitis, peptic ulcer disease, and hypersecretory conditions (e.g. Zollinger-Ellison syndrome), and as part of the eradication therapy for Helicobacter pylori bacteria. However, approximately 25% to 70% of people are prescribed a PPI inappropriately. Chronic PPI use without reassessment contributes to polypharmacy and puts people at risk of experiencing drug interactions and adverse events (e.g. Clostridium difficile infection, pneumonia, hypomagnesaemia, and fractures). OBJECTIVES To determine the effects (benefits and harms) associated with deprescribing long-term PPI therapy in adults, compared to chronic daily use (28 days or greater). SEARCH METHODS We searched the following databases: Cochrane Central Register of Controlled Trials (CENTRAL; 2016, Issue 10), MEDLINE, Embase, clinicaltrials.gov, and the World Health Organization International Clinical Trials Registry Platform (WHO ICTRP). The last date of search was November 2016. We handsearched the reference lists of relevant studies. We screened 2357 articles (2317 identified through search strategy, 40 through other resources). Of these articles, we assessed 89 for eligibility. SELECTION CRITERIA We included randomized controlled trials (RCTs) and quasi-randomized trials comparing at least one deprescribing modality (e.g. stopping PPI or reducing PPI) with a control consisting of no change in continuous daily PPI use in adult chronic users. Outcomes of interest were: change in gastrointestinal (GI) symptoms, drug burden/PPI use, cost/resource use, negative and positive drug withdrawal events, and participant satisfaction. DATA COLLECTION AND ANALYSIS Two review authors independently reviewed and extracted data and completed the risk of bias assessment. A third review author independently confirmed risk of bias assessment. We used Review Manager 5 software for data analysis. We contacted study authors if there was missing information. MAIN RESULTS The review included six trials (n = 1758). Trial participants were aged 48 to 57 years, except for one trial that had a mean age of 73 years. All participants were from the outpatient setting and had either nonerosive reflux disease or milder grades of esophagitis (LA grade A or B). Five trials investigated on-demand deprescribing and one trial examined abrupt discontinuation. There was low quality evidence that on-demand use of PPI may increase risk of 'lack of symptom control' compared with continuous PPI use (risk ratio (RR) 1.71, 95% confidence interval (CI) 1.31 to 2.21), thereby favoring continuous PPI use (five trials, n = 1653). There was a clinically significant reduction in 'drug burden', measured as PPI pill use per week with on-demand therapy (mean difference (MD) -3.79, 95% CI -4.73 to -2.84), favoring deprescribing based on moderate quality evidence (four trials, n = 1152). There was also low quality evidence that on-demand PPI use may be associated with reduced participant satisfaction compared with continuous PPI use. None of the included studies reported cost/resource use or positive drug withdrawal effects. AUTHORS' CONCLUSIONS In people with mild GERD, on-demand deprescribing may lead to an increase in GI symptoms (e.g. dyspepsia, regurgitation) and probably a reduction in pill burden. There was a decline in participant satisfaction, although heterogeneity was high. There were insufficient data to make a conclusion regarding long-term benefits and harms of PPI discontinuation, although two trials (one on-demand trial and one abrupt discontinuation trial) reported endoscopic findings in their intervention groups at study end.

Abstract
BACKGROUND & AIMS The purpose of this review is to evaluate the risks associated with long-term use of proton pump inhibitors (PPIs), focusing on long-term use of PPIs for three common indications: gastroesophageal reflux disease (GERD), Barrett's esophagus (BE), and non-steroidal anti-inflammatory drug (NSAID) bleeding prophylaxis. METHODS The recommendations outlined in this review are based on expert opinion and on relevant publications from PubMed, EMbase, and the Cochrane library (through July 2016). To identify relevant ongoing trials, we queried clinicaltrials.gov. To assess the quality of evidence, we used a modified approach based on the GRADE Working Group. The Clinical Practice Updates Committee of the American Gastroenterological Association has reviewed these recommendations. Best Practice Advice 1: Patients with GERD and acid-related complications (ie, erosive esophagitis or peptic stricture) should take a PPI for short-term healing, maintenance of healing, and long-term symptom control. Best Practice Advice 2: Patients with uncomplicated GERD who respond to short-term PPIs should subsequently attempt to stop or reduce them. Patients who cannot reduce PPIs should consider ambulatory esophageal pH/impedance monitoring before committing to lifelong PPIs to help distinguish GERD from a functional syndrome. The best candidates for this strategy may be patients with predominantly atypical symptoms or those who lack an obvious predisposition to GERD (eg, central obesity, large hiatal hernia). Best Practice Advice 3: Patients with Barrett's esophagus and symptomatic GERD should take a long-term PPI. Best Practice Advice 4: Asymptomatic patients with Barrett's esophagus should consider a long-term PPI. Best Practice Advice 5: Patients at high risk for ulcer-related bleeding from NSAIDs should take a PPI if they continue to take NSAIDs. Best Practice Advice 6: The dose of long-term PPIs should be periodically reevaluated so that the lowest effective PPI dose can be prescribed to manage the condition. Best Practice Advice 7: Long-term PPI users should not routinely use probiotics to prevent infection. Best Practice Advice 8: Long-term PPI users should not routinely raise their intake of calcium, vitamin B12, or magnesium beyond the Recommended Dietary Allowance (RDA). Best Practice Advice 9: Long-term PPI users should not routinely screen or monitor bone mineral density, serum creatinine, magnesium, or vitamin B12. Best Practice Advice 10: Specific PPI formulations should not be selected based on potential risks.

Abstract
BACKGROUND Proton pump inhibitors (PPI) are the most effective drugs for inhibiting gastric acid secretion. They have been in clinical use for more than 25 years, In 2014, 3.475 billion daily defined doses (DDD) of PPI were prescribed in Germany. This high number alone calls for a critical analysis of the spectrum of indications for PPI and their potential adverse effects. METHODS This review is based on pertinent publications retrieved by a selective search in the PubMed and Cochrane Library databases, with particular emphasis on randomized, prospective multicenter trials, cohort studies, case-control studies, and meta-analyses. RESULTS The inhibition of gastric acid secretion with PPI is successfully used for the treatment of gastroesophageal reflux disease and of gastric and duodenal ulcers, for the secondary prevention of gastroduodenal lesions that have arisen under treatment with nonsteroidal anti-inflammatory drugs and acetylsalicylic acid, and for the prevention of recurrent hemorrhage from ulcers after successful endoscopic hemostasis. PPI are given along with practically all antibiotic regimens for the eradication of Helicobacter pylori infection. The number of prescriptions for PPI has risen linearly over the past 25 years. As there has been no broadening of indications, one may well ask whether the current, extensive use of PPI is justified. There is evidence that patients taking PPI are at greater risk for fractures. Moreover, the vitamin B12 level should be checked occasionally in all patients taking PPI. CONCLUSION PPI are among the more effective drugs for the treatment of diseases associated with gastric acid. In view of their cost and potential adverse effects, they should only be prescribed for scientifically validated indications.

Abstract
Background Most patients with gastroesophageal reflux disease experience symptomatic relapse after stopping acid-suppressive medication. The aim of this study was to compare willingness to continue treatment with esomeprazole on-demand versus continuous maintenance therapy for symptom control in patients with non-erosive reflux disease (NERD) after 6 months. Methods This multicenter, open-label, randomized, parallel-group study enrolled adults with NERD who were heartburn-free after 4 weeks’ treatment with esomeprazole 20 mg daily. Patients received esomeprazole 20 mg daily continuously or on-demand for 6 months. The primary variable was discontinuation due to unsatisfactory treatment. On-demand treatment was considered non-inferior if the upper limit of the one-sided 95 % confidence interval (CI) for the difference between treatments was <10 %. Results Of 877 patients enrolled, 598 were randomized to maintenance treatment (continuous: n = 297; on-demand: n = 301). Discontinuation due to unsatisfactory treatment was 6.3 % for on-demand and 9.8 % for continuous treatment (difference −3.5 % [90 % CI: −7.1 %, 0.2 %]). In total, 82.1 and 86.2 % of patients taking on-demand and continuous therapy, respectively, were satisfied with the treatment of heartburn and regurgitation symptoms, a secondary variable (P = NS). Mean study drug consumption was 0.41 and 0.91 tablets/day, respectively. Overall, 5 % of the on-demand group developed reflux esophagitis versus none in the continuous group (P < 0.0001). The Gastrointestinal Symptom Rating Scale Reflux dimension was also improved for continuous versus on-demand treatment. Esomeprazole was well tolerated. Conclusions In terms of willingness to continue treatment, on-demand treatment with esomeprazole 20 mg was non-inferior to continuous maintenance treatment and reduced medication usage in patients with NERD who had achieved symptom control with initial esomeprazole treatment. Trial registration ClinicalTrials.gov identifier (NCT number): NCT02670642; Date of registration: December 2015.

Abstract
Background/Aims The aim of this study was to evaluate the efficacy and cost efficiency of omeprazole 10 mg and rabeprazole 10 mg once daily for 24 weeks in the maintenance therapy. Methods This was a randomized, open-label study enrolling 279 patients with erosive esophagitis A or B (Los Angeles classification) and typical gastroesophageal reflux disease symptoms. Patients who showed complete endoscopic and symptomatic healing after 8 weeks of proton pump inhibitor treatment were randomly allocated to maintenance treatment with omeprazole 10 mg once daily or rabeprazole 10 mg once daily for 42 weeks. The primary efficacy endpoint was the proportion of patients with symptomatic remission at 42 weeks. Results At the end of 42 weeks of maintenance therapy, 96.4% of omeprazole and 95.1% of rabeprazole treated patients remained symptom free (P > 0.05). Two drugs were also comparable with regard to the severity and frequency of reflux symptoms during the maintenance phase (P > 0.05). By the cost-minimization analysis, the mean total costs per patient for remaining symptom-free for 6 months were 241,775 won for omeprazole and 287,115 won for rabeprazole, respectively. Conclusions Omeprazole 10 mg appeared to have similar efficacy in maintaining symptomatic remission as rabeprazole 10 mg, but was superior to rabeprazole 10 mg in terms of cost efficiency in the maintenance therapy of gastroesophageal reflux disease symptoms.

Abstract
In 2010, a Korean guideline for the management of gastroesophageal reflux disease (GERD) was made by the Korean Society of Neurogastroenterology and Motility, in which the definition and diagnosis of GERD were not included. The aim of this guideline was to update the clinical approach to the diagnosis and management of GERD in adult patients. This guideline was developed by the adaptation process of the ADAPTE framework. Twelve guidelines were retrieved from initial queries through the Appraisal of Guidelines for Research & Evaluation II process. Twenty-seven statements were made as a draft and revised by modified Delphi method. Finally, 24 consensus statements for the definition (n=4), diagnosis (n=7) and management (n=13) of GERD were developed. Multidisciplinary experts participated in the development of the guideline, and the external review of the guideline was conducted at the finalization phase.

Abstract
Background/Aims There have been few studies on the efficacy of proton pump inhibitors and the doses required to treat dyspeptic symptoms observed in clinical practice. The aim of this study was to compare the efficacy of different doses of omeprazole and different administration methods in Helicobacter pylori-negative, dyspeptic patients. Methods Patients with chronic upper abdominal symptoms within the previous 3 months were randomly divided into three groups: a daily, omeprazole 20 mg treatment group (OPZ20, n=61); a daily, omeprazole 10 mg treatment group (OPZ10, n=72); and an on-demand omeprazole 20 mg treatment group (on-demand, n=62). After 4 weeks of administration of the drug, symptom improvement rates were evaluated based on the Overall Global Severity score. Results The rates of symptom improvement after 4 weeks of treatment were 65.6% (40/61) in the OPZ20 group, 47.2% (34/72) in the OPZ10 group, and 50.0% (31/62) in the on-demand group. The OPZ20 group exhibited a significantly higher improvement rate (p=0.034) than the OPZ10 group. The OPZ20 group had significant improvements in regurgitation, postprandial fullness, vomiting, and bloating compared with the OPZ10 group. Conclusions Daily treatment with 20 mg of omeprazole was efficient in treating upper abdominal symptoms. Trial registration: ClinicalTrials.gov, number UMIN000002621.

Abstract
OPINION STATEMENT Considerable clinical experience with proton pump inhibitors (PPIs) attests to their efficacy and safety in short-and long-term therapy for gastroesophageal reflux disease (GERD) in erosive esophagitis and endoscopy-negative (NERD) patients. One alternative to continuous PPI maintenance is PPI therapy administered noncontinuously (eg, "on demand"). Qualities of good PPI therapy for such a modality should include fast and sustained acid suppression. The newer-generation PPI esomeprazole has provided greater acid inhibition. Randomized controlled clinical trials comparing on-demand PPI versus placebo or versus continuous PPI therapy in GERD patients have shown that on-demand therapy with currently available PPIs (esomeprazole in particular) appears to be effective in the long-term management of patients with NERD or mild esophagitis and uninvestigated forms of GERD, who make up the overwhelming majority of patients with GERD. This is because it is safe and provides adequate symptom control and sustains quality of life. However, it is not indicated in patients with severe erosive esophagitis or with complicated esophagitis (ie, Barrett's esophagus or stricture). On-demand PPI therapy is important for economic reasons, as it may save up to two thirds of daily doses of the drugs, with a considerable containment of drug expenses. For a long-term disease whose treatment is aimed primarily at symptom control, it is a sensible and cost-effective approach.

Abstract
Gastroesophageal reflux disease (GERD) is defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. In the last decade, GERD has been increasing in Korea. Seventeen consensus statements for the treatment of GERD were developed using the modified Delphi approach. Acid suppression treatments, such as proton pump inhibitors (PPIs), histmine-2 receptor antagonists and antacids are effective in the control of GERD-related symptoms. Among them, PPIs are the most effective medication. Standard dose PPI is recommended as the initial treatment of erosive esophagitis (for 8 weeks) and non-erosive reflux disease (at least for 4 weeks). Long-term continuous PPI or on-demand therapy is required for the majority of GERD patients after the initial treatment. Anti-reflux surgery can be considered in well selected patients. Prokinetic agents and mucosal protective drugs have limited roles. Twice daily PPI therapy can be tried to control extra-esophageal symptoms of GERD. For symptomatic patients with Barrett's esophagus, long-term treatment with PPI is required. Further studies are strongly needed to develop better treatment strategies for Korean patients with GERD.

Abstract
BACKGROUND Despite the high prevalence of gastro-oesophageal reflux disease (GORD) and the documented impact of GORD symptoms on individual health-related quality of life (HR-QOL) and on socioeconomic factors, structured management of GORD has had a low priority in Swedish routine primary health care. OBJECTIVE The primary objective of this study (IMPROVE) was to evaluate the effects of a structured follow-up and management regimen for primary-care GORD patients with symptomatic breakthrough despite standard proton pump inhibitor (PPI) treatment. Patients received either an increased dose of current PPI treatment or were switched to the more effective acid inhibitor esomeprazole. METHODS GORD patients with symptomatic breakthrough despite standard PPI treatment were identified through medical records and by a postal survey using the GERD Impact Scale (GIS) questionnaire. Patients rated the severity and frequency of GORD symptoms, general health status (EuroQol Group 5-Dimension Self-Report Questionnaire) and the impact of GORD symptoms on work productivity (Work Productivity and Activity Impairment) before and 4 weeks following randomization to open-label treatment with either increased acid suppressive therapy or an adjusted, higher dosage of the PPI previously used. The patients' valuation, in monetary terms, of the treatment they received pre-study versus the treatment given during the study was documented through willingness-to-pay (WTP) questions. RESULTS Following more effective acid suppression, 66.3% of the study population experienced complete relief of heartburn, with no difference between the groups; HR-QOL was restored to a level comparable to that of a normal Swedish population and ability to work efficiently was significantly improved. Access to a better acid suppressive treatment was highly valuable to the patients in terms of WTP. CONCLUSION An improved GORD management strategy including structured follow-up of treatment given and initiation of more effective acid inhibitor therapy when symptoms persist will be of great benefit to GORD patients.

Abstract
Background/Aims Gastroesophageal reflux disease is one of the most common and frequent chronic disease requiring considerable cost. We investigated the medical care costs in the erosive reflux disease (ERD) and non-erosive reflux disease (NERD). Methods The risk factors and the direct medical care costs were analyzed retrospectively in the ERD (178 patients) and NERD (183 patients) groups for a follow up period of 2 years. Results Logistic regression analysis showed that the ERD was more frequent in the groups of male gender, alcohol consumption, higher body mass index (≥25 kg/m2), hiatal hernia, and higher triglyceride levels (≥150 mg/dL). The direct medical care costs per person for 2 years were found to be $384.8 (ERD) and $412.9 (NERD) without statistically significant differences (p = 0.364). However, 9.3% (17/183) of the NERD patients had visited the emergency room compared to 3.4% (6/178) of the ERD patients (p = 0.029). In addition, more NERD patients were hospitalized than ERD patients (p = 0.006), and because of the longer hospitalization period, the medical costs in NERD patients were higher than ERD patients (p = 0.038). Conclusions In spite of the different risk factors for ERD and NERD, total direct medical care costs were similar between the ERD and NERD group. However, more visits to emergency room and longer hospitalization period with more hospitalization costs in NERD patients account for the differences in medical service and usage distribution between the 2 groups.

Abstract
Esomeprazole (S-isomer of omeprazole) demonstrates a better pharmacokinetic/pharmacodynamic profile than the racemic product omeprazole. Esomeprazole's pharmacological activity of gastric acid secretion is through proton pump inhibition. The pharmacokinetic properties provide for an enhanced pharmacological effect. Esomeprazole is rapidly absorbed and the extent of absorption is higher resulting in higher systemic absorption of esomeprazole (bioavailability), which coupled with reduced clearance results in greater systemic exposure. This pharmacodynamic profile then provides for a prolongation of inhibition of gastric acid output and correlates well with its more beneficial therapeutic efficacy over omeprazole and some of the other proton-pump inhibitors. It has been well proven as an effective agent in the treatment of gastro-esophagitis reflux disease, (reflux esophagitis and non-erosive reflux disease), NSAID-induced gastric-intestinal symptoms and ulcers, Helicobacter pylori infection and Zollinger-Ellison syndrome. Esomeprazole has a good tolerability profile and a low potential for drug interaction.

Abstract
BACKGROUND There has been no report on the response to proton pump inhibitor (PPI) therapy and on-demand or the relapse rate of non-erosive reflux disease (NERD) and erosive oesophagitis in Korea. AIM To compare the risk factors, clinical symptoms and PPI responses between patients with erosive oesophagitis and NERD patients. METHODS A survey was performed prospectively in the erosive oesophagitis (205 patients) and NERD group (200 patients). Clinical symptoms, risk factors and PPI responses were analysed. On-demand therapy and the relapse rate of GERD symptoms were investigated during a one-year follow-up. RESULTS BMI > or = 25 (OR 3.0, 95% CI 1.1-8.3), alcohol use (OR 2.9, 95% CI 1.0-8.3), hiatal hernia (OR 5.0, 95% CI 1.2-20) and triglyceride > or =150 mg/dL (OR 4.0, 95% CI 1.7-10) were more common in the erosive oesophagitis group than in the NERD group by multivariate analysis. The ratio of oesophageal to extra-oesophageal symptoms was higher in the erosive oesophagitis group compared with the NERD group (P < 0.001). The PPI response rates at 8 weeks were different (P = 0.02); refractory rates were higher in the NERD group (16.7%) compared with the erosive oesophagitis group (6.0%). However, there was no significant difference between the two groups in on-demand therapy or the relapse rate. CONCLUSION These results suggest that the underlying pathogenic mechanisms of erosive oesophagitis and NERD are distinct.

Abstract
OBJECTIVES To assess the difference in direct medical costs between on-demand (OD) treatment with esomeprazole (E) 20 mg and continuous (C) treatment with E 20 mg q.d. from a clinical practice view in patients with gastroesophageal reflux disease (GERD) symptoms. METHODS This open, randomized study (ONE: on-demand Nexium evaluation) compared two long-term management options with E 20 mg in endoscopically uninvestigated patients seeking primary care for GERD symptoms who demonstrated complete relief of symptoms after an initial treatment of 4 weeks with E 40 mg. Data on consumed quantities of all cost items were collected in the study, while data on prices during the time of study were collected separately. The analysis was done from a societal perspective. RESULTS Forty-nine percent (484 of 991) of patients randomized to the OD regimen and 46% (420 of 913) of the patients in the C group had at least one contact with the investigator that would have occurred nonprotocol-driven. The difference of the adjusted mean direct medical costs between the treatment groups was CHF 88.72 (95% confidence interval: CHF 41.34-153.95) in favor of the OD treatment strategy (Wilcoxon rank-sum test: P < 0.0001). Adjusted direct nonmedical costs and productivity loss were similar in both groups. CONCLUSIONS The adjusted direct medical costs of a 6-month OD treatment with esomeprazole 20 mg in uninvestigated patients with symptoms of GERD were significantly lower compared with a continuous treatment with E 20 mg once a day. The OD therapy represents a cost-saving alternative to the continuous treatment strategy with E.

Abstract
Proton pump inhibitors (PPIs) are the most potent inhibitors of gastric acid secretion available, and they are effective for treating all acid-related disorders. Esomeprazole is one of several most recent PPIs that became available to the market in 2001. Esomeprazole is indicated for the treatment of gastroesophageal reflux disease in adults and children, risk reduction of NSAIDs-associated gastric ulcer, Helicobacter pylori eradication and control of pathological hypersecretory conditions associated with Zollinger-Ellison syndrome. Esomeprazole is available in both oral and intravenous formulations. A number of studies have compared esomeprazole with other PPIs. While differences supporting esomeprazole have been reported, the magnitude of differences has been variable and of uncertain clinical importance. Cost plays a major role in prescribing patterns of PPIs.

Abstract
Gastroesophageal reflux disease (GERD) is currently defined as a condition that develops when the reflux of stomach contents causes recurrent symptoms and/or complications. The clinical presentation of GERD has been recognized to be much broader than before, when the typical symptoms of heartburn and acid regurgitation were considered as the main clinical presentation. However, now it is recognized that GERD can present with various other mainly extraesophageal symptoms, abdominal pain, and even sleep disturbance. Moreover, there is an important overlap with functional gastrointestinal disorders such as functional dyspepsia and irritable bowel syndrome. The morphologic spectrum of esophageal involvement in GERD encompasses erosive (erosive reflux disease ), Barrett's esophagus (BE), and nonerosive reflux disease (NERD). However, there is still no consensus on whether GERD represents one disease that can progress from NERD to ERD and BE, or whether it is a spectrum of different conditions with its own clinical, pathophysiologic, and endoscopic characteristics. Recently published data suggest that mild erosive esophagitis behaves in a way similar to NERD and that there is considerable movement between these categories. But follow-up data also show that after 2 years, some patients with NERD or GERD Los Angeles A or B went on to develop severe GERD or even BE. A practical approach is to categorize patients with reflux symptoms into "functional heartburn" (ie, reflux symptoms and negative endoscopy and absent objective evidence of acid reflux into the esophagus), NERD (negative endoscopy but positive documentation of acid reflux into the esophagus), and ERD (erosions documented endoscopically). In conclusion, it appears that GERD is a disease with a spectrum of clinical and endoscopic manifestations, with characteristics that make it a continuum and not a categorical condition with separate entities. It is difficult to clearly delineate the spectrum of GERD based on the clinical, endoscopic, and pathophysiologic characteristics, but therapeutic trials and follow-up studies suggest that GERD is not composed of different conditions.

Abstract
OBJECTIVE To evaluate continuous therapy (COT) and on-demand therapy (ODT) with rabeprazole 20 mg for maintenance in uninvestigated gastroesophageal reflux disease (GERD). METHODS This randomized, open-label study enrolled 331 GERD (heartburn-predominant) patients with a pre-existing proton pump inhibitor history of one month or longer, to an acute four-week trial with 20 mg rabeprazole daily for heartburn management. Patients who achieved satisfactory heartburn control during the acute phase (three days or less of heartburn, with no more than one episode rated as moderate, and heartburn rated satisfactorily or completely controlled with minimal rescue antacid use in the seven days preceding randomization) were randomly assigned to six months of rabeprazole 20 mg given as either daily COT or daily ODT, which was initiated upon symptom recurrence and stopped upon symptom resolution. Rescue antacid usage was permitted and tracked. Primary efficacy was measured as the proportion of heartburn-free days over six months. RESULTS For the 268 patients, the mean percentage of heartburn-free days for the COT group and for the ODT group were 90.3%+/-14.8% and 64.8%+/-22.3%, respectively (P<0.0001). COT was associated with an increased number of medication intake days (154+/-40.2) versus ODT (68+/-46.1), with less heartburn episodes observed with COT versus ODT, respectively (n=7, n=26, P<0.0001). Ninety-two per cent of COT patients and 79% of ODT patients were either 'satisfied' or 'very satisfied' with treatment. The mean usage of antacids was low and similar in both groups. COT and ODT regimens were safe and well-tolerated, with a similar incidence of adverse events. CONCLUSION Results based on symptom assessments favour COT with rabeprazole 20 mg for maintenance therapy in patients with uninvestigated GERD; however, both therapy types are safe and acceptable treatment options for selected patients.

Abstract
BACKGROUND Proton pump inhibitors (PPI) therapy 'on-demand' is often used as an alternative to continuous maintenance therapy in gastro-oesophageal reflux disease (GERD). AIM We conducted a systematic review with the specific objectives to ascertain whether on-demand PPI therapy was effective in preventing symptomatic relapse and to assess the relative efficacy of on-demand vs. continuous PPI maintenance strategy. METHODS Randomized-controlled clinical trials comparing on-demand PPI vs. placebo or on-demand vs. continuous PPI therapy in GERD patients were identified by searching the Medline database and the Cochrane Controlled Trials Register. RESULTS Seventeen studies were found which met inclusion criteria. Out of the 17 studies: five investigated exclusively patients with non-erosive reflux disease (NERD), four patients with NERD and mild oesophagitis, two patients with erosive oesophagitis only, and two patients with uninvestigated GERD symptoms, respectively. Four further studies were not investigating the effectiveness of the therapies but primarily pharmacoeconomic or quality of life parameters. CONCLUSIONS On the basis of the analysis of 17 studies, we can conclude that on-demand therapy with currently available PPI appears to be effective in the long-term management of patients with NERD or mild and uninvestigated forms of GERD, but not in patients with (severe) erosive oesophagitis.

Abstract
BACKGROUND Gastro-oesophageal reflux disease (GERD) is a common condition frequently requiring long-term pharmacological treatment. AIM To describe the long-term pattern of GERD medication use in GERD patients receiving routine care. METHODS Patients were recruited as part of the ongoing ProGERD study, a 10-year-cohort study including 6215 patients at baseline. GERD medication and symptoms were assessed with patient questionnaires. During follow-up, medical treatment was prescribed by participating primary care physicians. Associations between patient characteristics and medication were analysed by logistic regression. RESULTS The percentage of patients who reported using any GERD medication remained constant from year 1 to year 4 (74%, 74%, 73% and 71%). Of patients who reported using GERD medication, the majority were taking proton pump inhibitors (PPI) (79%, 84%, 85%, and 87%). Continuous PPI intake was the predominant prescription pattern (53%, 49%, 56% and 56%), followed by on-demand treatment (26%, 35%, 29% and 29%). Continuous PPI intake was strongly associated with the presence of erosive GERD. CONCLUSION Three-quarters of the GERD population in our study reported long-term treatment with a PPI. Continuous PPI intake was the predominant treatment pattern, and the proportion of patients taking a PPI on a continuous basis remained constant over time.

Abstract
The following pages summarize the proceedings of a symposium held in May 2006 on the emerging role of on-demand therapy for gastroesophageal reflux disease (GERD). Medical therapy for GERD has undergone significant change in recent years with the advent of effective, but expensive, antisecretory agents. On-demand (patient-driven) therapy is attractive to payers and patients, because it appears to be both cost-effective and convenient. Many individuals appear to accept occasional symptomatic breakthrough in exchange for personal control of their disease. On-demand therapy should be distinguished from intermittent therapy, which is either patient- or physician-driven, but which requires intermittent episodes of continuous therapy followed by discontinuation until symptoms recur. Proton pump inhibitors appear to be effective on-demand agents despite theoretical pharmacodynamic limitations for this class of drug. The available data support the use of on-demand therapy for GERD in uninvestigated reflux disease, nonerosive reflux disease, and possibly mild esophagitis as well. On-demand therapy should not be considered for patients with severe esophagitis.

Abstract
AIM To compare antisecretory effects of rabeprazole and esomeprazole after single and repeat dosing in Helicobacter pylori-negative healthy volunteers. METHODS Results were pooled from three smaller, open, crossover, randomized studies to obtain data from 80 subjects. The studies compared: (a) 5 days' dosing of 20 mg rabeprazole and esomeprazole (n = 24); (b) single doses of rabeprazole 20 mg and esomeprazole 40 mg (n = 27) and (c) 5 days' dosing of rabeprazole 10 mg and esomeprazole 20 mg (n = 29). Washout periods were > or =14 days. Intragastric pH was recorded continuously for 24 h on days 0, 1 and 5. RESULTS Single doses of rabeprazole 20 mg maintained 24-h intragastric pH >4 for longer than esomeprazole 20 mg (45% vs. 32%; P < 0.001); rabeprazole 20 mg and esomeprazole 40 mg were equivalent in their effects. After 5 days' dosing, rabeprazole 20 mg maintained pH >4 for longer than esomeprazole 20 mg (62% vs. 56%; P = 0.046); the reverse was true for esomeprazole 20 mg vs. rabeprazole 10 mg (56% vs. 48%; P = 0.035). In general, intragastric pH AUC during 0-5 h after dosing was higher after esomeprazole than rabeprazole, whereas the reverse was true during the night. CONCLUSIONS The order of effects on 24-h pH was: rabeprazole 10 mg < or = esomeprazole 20 mg < rabeprazole 20 mg = esomeprazole 40 mg. Esomeprazole acts faster, whereas rabeprazole's effect lasts longer.

Abstract
BACKGROUND Proton pump inhibitors are widely used, but little is known about the usage pattern in different indications. AIM To analyse proton pump inhibitor usage patterns in the general population. METHODS A cohort of 16 311 incident proton pump inhibitor users was identified in the Integrated Primary Care Information database, a Dutch general practice research database. Persistence and adherence were calculated by indication. Risk factors were identified by logistic regression analysis. RESULTS One-year persistence was 31% in patients using proton pump inhibitors for gastro-oesophageal reflux. Persistence was higher in oesophagitis grade A/B (54%), grade C/D (73%) and Barrett's oesophagus (72%), compared to patients with only reflux symptoms (27%). Approximately 25% of patients with non-reflux dyspepsia or Helicobacter pylori-associated indications used proton pump inhibitors for more than 6 months. Half of all patients used proton pump inhibitors <80% of time indicating intermittent use, which was independent of indication. Exception were patients with Barrett's oesophagus, who were most adherent. CONCLUSIONS A substantial proportion of patients with indications not requiring long-term treatment use proton pump inhibitors for an extended period. Half of the patients used proton pump inhibitors on-demand or intermittently. Such usage pattern is probably sufficient for most patients, but may be inadequate if proton pump inhibitors are used for serious diseases, such as severe oesophagitis or Barrett's oesophagus.

Abstract
Gastro-oesophageal reflux disease refers to reflux of gastric contents into the oesophagus leading to oesophagitis, reflux symptoms sufficient to impair quality of life, or long-term complications. Transient relaxation of the lower oesophageal sphincter is believed to be the primary mechanism of the disease although the underlying cause remains uncertain. Obesity and smoking are weakly associated with the disease and genetic factors might be important. A negative association with Helicobacter pylori exists, but eradication of H pylori does not seem to cause reflux disease. Diagnosis is imprecise as there is no gold standard. Reflux symptoms are helpful in diagnosis but they lack sensitivity. Ambulatory oesophageal pH monitoring also seems to be insensitive despite high specificity. Empirical acid suppression with a proton-pump inhibitor (PPI) has reasonable sensitivity but poor specificity. Some evidence suggests that once patients develop the disease, severity is determined early and patients seem to continue with that phenotype long term. Unfortunately, most patients do not respond to life-style advice and require further therapy. H2 receptor antagonists and PPIs are better than placebo in oesophagitis, with a number needed to treat of five and two, respectively. In non-erosive reflux disease, acid suppression is better than placebo but the response rate is lower. Most patients need long-term treatment because the disease usually relapses. The role of endoscopic therapy is uncertain. Anti-reflux surgery is probably as effective as PPI therapy although there is a low operative mortality and morbidity.
