RESUMEN
OBJECTIVE: The objective of this work was to gather an international consensus group to propose a global definition and diagnostic approach of laryngopharyngeal reflux (LPR) to guide primary care and specialist physicians in the management of LPR. METHODS: Forty-eight international experts (otolaryngologists, gastroenterologists, surgeons, and physiologists) were included in a modified Delphi process to revise 48 statements about definition, clinical presentation, and diagnostic approaches to LPR. Three voting rounds determined a consensus statement to be acceptable when 80% of experts agreed with a rating of at least 8/10. Votes were anonymous and the analyses of voting rounds were performed by an independent statistician. RESULTS: After the third round, 79.2% of statements (N = 38/48) were approved. LPR was defined as a disease of the upper aerodigestive tract resulting from the direct and/or indirect effects of gastroduodenal content reflux, inducing morphological and/or neurological changes in the upper aerodigestive tract. LPR is associated with recognized non-specific laryngeal and extra-laryngeal symptoms and signs that can be evaluated with validated patient-reported outcome questionnaires and clinical instruments. The hypopharyngeal-esophageal multichannel intraluminal impedance-pH testing can suggest the diagnosis of LPR when there is >1 acid, weakly acid or nonacid hypopharyngeal reflux event in 24 h. CONCLUSION: A global consensus definition for LPR is presented to improve detection and diagnosis of the disease for otolaryngologists, pulmonologists, gastroenterologists, surgeons, and primary care practitioners. The approved statements are offered to improve collaborative research by adopting common and validated diagnostic approaches to LPR. LEVEL OF EVIDENCE: 5 Laryngoscope, 134:1614-1624, 2024.

The Lyon Consensus provides conclusive criteria for and against the diagnosis of gastro-oesophageal reflux disease (GERD), and adjunctive metrics that consolidate or refute GERD diagnosis when primary criteria are borderline or inconclusive. An international core and working group was assembled to evaluate research since publication of the original Lyon Consensus, and to vote on statements collaboratively developed to update criteria. The Lyon Consensus 2.0 provides a modern definition of actionable GERD, where evidence from oesophageal testing supports revising, escalating or personalising GERD management for the symptomatic patient. Symptoms that have a high versus low likelihood of relationship to reflux episodes are described. Unproven versus proven GERD define diagnostic strategies and testing options. Patients with no prior GERD evidence (unproven GERD) are studied using prolonged wireless pH monitoring or catheter-based pH or pH-monitoring off antisecretory medication, while patients with conclusive GERD evidence (proven GERD) and persisting symptoms are evaluated using pH-impedance monitoring while on optimised antisecretory therapy. The major changes from the original Lyon Consensus criteria include establishment of Los Angeles grade B oesophagitis as conclusive GERD evidence, description of metrics and thresholds to be used with prolonged wireless pH monitoring, and inclusion of parameters useful in diagnosis of refractory GERD when testing is performed on antisecretory therapy in proven GERD. Criteria that have not performed well in the diagnosis of actionable GERD have been retired. Personalisation of investigation and management to each patient's unique presentation will optimise GERD diagnosis and management.

BACKGROUND: Laryngopharyngeal reflux (LPR) is a common otolaryngologic diagnosis. Treatment of presumed LPR remains challenging, and limited frameworks exist to guide treatment. METHODS: Using RAND/University of California, Los Angeles (UCLA) Appropriateness Methods, a modified Delphi approach identified consensus statements to guide LPR treatment. Experts independently and blindly scored proposed statements on importance, scientific acceptability, usability, and feasibility in a four-round iterative process. Accepted measures reached scores with ≥ 80% agreement in the 7-9 range (on a 9-point Likert scale) across all four categories. RESULTS: Fifteen experts rated 36 proposed initial statements. In round one, 10 (27.8%) statements were rated as valid. In round two, 8 statements were modified based on panel suggestions, and experts subsequently rated 5 of these statements as valid. Round three's discussion refined statements not yet accepted, and in round four, additional voting identified 2 additional statements as valid. In total, 17 (47.2%) best practice statements reached consensus, touching on topics as varied as role of empiric treatment, medication use, lifestyle modifications, and indications for laryngoscopy. CONCLUSION: Using a well-tested methodology, best practice statements in the treatment of LPR were identified. The statements serve to guide physicians on LPR treatment considerations.

INTRODUCTION: Ambulatory reflux monitoring performed off proton pump inhibitor (PPI) is the gold standard diagnostic test for nonerosive gastroesophageal reflux disease (GERD). However, the diagnostic metrics and optimal duration of monitoring are not well defined. This study evaluated the performance of multiple metrics across distinct durations of wireless reflux monitoring off PPI against the ability to discontinue PPI therapy in patients with suboptimal PPI response. METHODS: This single-arm clinical trial performed over 4 years at 2 centers enrolled adults with troublesome GERD symptoms and inadequate response to > 8 weeks of PPI. Participants underwent 96-hour wireless pH monitoring off PPI. Primary outcome was whether the subject successfully discontinued PPI or resumed PPI within 3 weeks. RESULTS: Of 132 participants, 30% discontinued PPI. Among multiple metrics assessed, total acid exposure time (AET) of 4.0% performed best in predicting PPI discontinuation (odds ratio 2.9 [95% confidence interval 1.4, 6.4]; P = 0.006), with other thresholds of AET and DeMeester score performing comparably. AET was significantly higher on day 1 of monitoring compared with other days, and prognostic performance significantly declined when only assessing the first 48 hours of monitoring (area under the curve for 96 hours 0.63 vs area under the curve for 48 hours 0.57; P = 0.01). DISCUSSION: This clinical trial highlights the AET threshold of 4.0% as a high-performing prognostic marker of PPI discontinuation. 96 hours of monitoring performed better than 48 hours, in predicting ability to discontinue PPI. These data can inform current diagnostic approaches for patients with GERD symptoms who are unresponsive to PPI therapy.

INTRODUCTION: This is the first randomized controlled diet intervention trial to investigate both the amount and type of carbohydrate on symptomatic gastroesophageal reflux disease (GERD). METHODS: Ninety-eight veterans with symptomatic GERD were randomly assigned to high total/high simple, high total/low simple, low total/high simple, or low total/low simple carbohydrate diet for 9 weeks. The primary outcomes were esophageal acid exposure time (AET) and total number of reflux episodes derived from 24-hour ambulatory pH monitoring. Secondary outcomes were esophageal reflux symptoms rated using the Gastroesophageal Reflux Disease Questionnaire (GERDQ) and GERD Symptom Assessment Scale (GSAS). RESULTS: Half of the subjects were White and half African American (mean age, 60.0 ± 12.5 years; mean body mass index, 32.7 ± 5.4 kg/m 2 ). There was a significant main effect of diet treatment on AET ( P = 0.001) and on the total number of reflux episodes ( P = 0.003). The change in AET in the high total/low simple group (-4.3% ± 3.8%) differed significantly from the high total/high simple control group (+3.1% ± 3.7%), (P = 0.04). The reduction in simple sugar intake averaged 62 g less per day. Subjects' ratings of symptoms improved in all carbohydrate modification groups, including significant reductions in heartburn frequency, heartburn severity, acid taste in the mouth, lump/pain in the throat or chest, and sleep disturbance. DISCUSSION: A modification of dietary carbohydrate intake that targeted a substantial reduction in the intakes of simple sugars improved pH monitoring outcomes and symptoms of GERD that profoundly affect daily life. These findings provide a feasible and clinically applicable contribution to the limited objective data existing for efficacious dietary recommendations in the routine treatment and management of GERD.

BACKGROUND: Optimal ambulatory reflux monitoring methodology in symptomatic reflux patients continues to be debated. AIMS: To utilise published literature and expert opinion to develop recommendation statements addressing use of ambulatory reflux monitoring in clinical practice METHODS: The RAND Appropriateness Method (RAM) was utilised among 17 experts with discussion, revision and two rounds of ranking of recommendation statements. Ambulatory reflux monitoring protocol, methodology and thresholds ranked as appropriate by ≥80% of panellists met the criteria for appropriateness. RESULTS: Prolonged (96-h recommended) wireless pH monitoring off proton pump inhibitor (PPI) was identified as the appropriate diagnostic tool to assess the need for acid suppression in patients with unproven gastro-oesophageal reflux disease (GERD) and persisting typical reflux symptoms despite once-daily PPI. Acid exposure time (AET) <4.0% on all days of monitoring with negative reflux-symptom association excludes GERD and does not support ongoing PPI treatment. Conversely, AET >6.0% across ≥2 days is conclusive evidence for GERD and supports treatment for GERD, while AET >10% across ≥2 days identifies severe acid burden that supports escalation of anti-reflux treatment. In previously proven GERD, impedance-pH monitoring on PPI is helpful in defining refractory GERD and mechanisms of continued symptoms; the presence of <40 reflux events, AET <2.0% and a negative reflux-symptom association does not support escalation of anti-reflux treatment. In contrast, AET > 4.0% and positive reflux-symptom association support escalation of anti-reflux treatment, including use of invasive therapeutics. CONCLUSIONS: Statements meeting appropriateness for average clinical care have been identified when utilising reflux monitoring in patients with typical reflux symptoms and PPI non-response.

OBJECTIVE: Management of erosive oesophagitis (EE) remains suboptimal, with many patients experiencing incomplete healing, ongoing symptoms, and relapse despite proton pump inhibitor (PPI) treatment. The Study of Acid-Related Disorders investigated patient burden of individuals with EE in a real-world setting. DESIGN: US gastroenterologists (GIs) or family physicians (FPs)/general practitioners (GPs) treating patients with EE completed a physician survey and enrolled up to four patients with EE for a patient survey, with prespecified data extracted from medical records. RESULTS: 102 GIs and 149 FPs/GPs completed the survey; data were available for 73 patients (mean age at diagnosis, 45.4 years). Omeprazole was healthcare professional (HCP)-preferred first-line treatment (60.8% GIs; 56.4% FPs/GPs), and pantoprazole preferred second line (29.4% and 32.9%, respectively). Price and insurance coverage (both 55.5% HCPs) and familiarity (47.9%) key drivers for omeprazole; insurance coverage (52.0%), price (50.0%), familiarity (48.0%), initial symptom relief (46.0%), and safety (44.0%) key drivers for pantoprazole. Only 49.3% patients took medication as instructed all the time; 56.8% independently increased medication frequency some of the time. Despite treatment, 57.5% patients experienced heartburn and 30.1% regurgitation; heartburn was the most bothersome symptom. 58.9% patients believed that their symptoms could be better controlled; only 28.3% HCPs were very satisfied with current treatment options. 83.6% patients wanted long-lasting treatment options. Fast symptom relief for patients was a top priority for 66.1% HCPs, while 56.6% would welcome alternatives to PPIs. CONCLUSION: This real-world multicentre study highlights the need for new, rapidly acting treatments in EE that reduce symptom burden, offer durable healing and provide symptom control.

Background: Rising prevalence of gastroesophageal reflux disease (GERD) in US Veterans is concurrent with increasing excess body weight. Objective: The objective of this cross-sectional study is to examine relationships between dietary macronutrients, gastrointestinal hormones, and GERD status. Methods: Ninety-eight veterans with overweight/obesity and empiric proton pump inhibitor (PPI) treatment were enrolled from the Tennessee Valley Healthcare System. Subjects had esophageal manometry and 24-h pH monitoring. Subjective symptoms were assessed with Gastroesophageal Reflux Disease Questionnaire (GERDQ) and Symptom Assessment Scale (GSAS). The primary outcomes, total acid exposure time (AET) and number of reflux episodes, enabled categorizing subjects as either pathologic GERD or inconclusive GERD. Data analysis included independent T-tests, Spearman Rho correlations, and multivariable linear regression modeling. Results: Higher intake of sugar-sweetened beverages (sugar-sweetened tea, soda, and fruit juice) associated with higher AET. Higher saturated-to-unsaturated fat intake is associated with higher AET and number of reflux episodes. Overall, sugar-sweetened beverage intake, saturated-to-unsaturated fat ratio, tomato-based food items, glucagon-like polypeptide 1 (GLP-1) level, time of first meal, and education status accounted for a significant amount of the variability in AET. Pathologic GERD subjects reported more heartburn (p = 0.006), regurgitation (p = 0.01), acid taste (0.001), and nausea severity (p = 0.04). GERDQ score associated with AET (r = 0.31, p = 0.005), but GSAS did not (r = 0.12, p = 0.28). Conclusion: Of the many foods and nutrients tested, the type (not amount) of carbohydrate (simple sugars) and the type (not amount) of fat (saturated vs unsaturated fat) consumed associated with objective and/or subjective GERD testing. These novel findings contribute to the evidence base guiding specific dietary recommendations in the clinical management of GERD.
RESUMEN
BACKGROUND & AIMS: Studies with limited sample sizes have investigated association of chronic opioid use with motility disorders of esophagogastric junction and esophageal body peristalsis. Our aims were to use a large cohort of patients to assess (1) the impact of opioid exposure on clinical and manometric characteristics, and (2) the association of opioid exposure with higher long-term symptom burden. METHODS: Patients recruited from a tertiary medical center who underwent high-resolution manometry (HRM) between 2007 and 2018 were included. Demographics, opiate exposure, clinical symptoms, and HRM parameters were compared. Patient-Reported Outcomes Measurement Information System-Gastrointestinal swallowing domain (PROMIS-GI swallowing domain) and Eckardt score were administered via phone interviews in patients with hypercontractile esophagus (HE) or distal esophageal spasm (DES) to determine long-term symptom burden between opioid and nonopioid users. RESULTS: Our cohort included 4075 patients (869 with opiate exposure with median morphine milligram equivalent [interquartile range] of 30 [10-45]). Patients in the opioid group were significantly more likely to have dysphagia (65% vs 51%, P < .01) and diagnosis of DES (11% vs 5%, P < .01) and HE (9% vs 3%, P < .01). Partial opioid agonists were not associated with motility abnormalities. Patients on opioids had significantly higher symptom burden on median (interquartile range) follow-up of 8.9 years (5.8-10.4) post manometric diagnosis with median PROMIS-GI swallowing domain score of 21.5 (17-25) compared with the nonopioid group at 15 (9.8-21, P = .03). CONCLUSIONS: Nearly 2 of 3 patients with opioid exposure undergoing HRM have dysphagia and more than 25% of them with dysphagia as the primary symptom have a diagnosis of either DES or HE. Opioid users with spastic disorders have higher symptom burden long-term compared with nonopioid users.

BACKGROUND: Refractory reflux-like symptoms have a substantial impact on patients and healthcare providers. The aim of the survey was to qualitatively assess the needs and attitudes of practicing clinicians around the management of refractory reflux symptoms and refractory gastroesophageal reflux disease (rGERD). METHODS: An International Working Group for the Classification of Oesophagitis (IWGCO) steering committee invited clinicians to complete an online survey including 17 questions. KEY RESULTS: Of the 113 clinicians who completed the survey, 70% were GIs, 20% were primary care physicians, and 10% were other specialties. Functional heartburn was considered the most common reason for an incomplete response to proton pump inhibitor (PPI) therapy (82%), followed by stress/anxiety (69%). More GIs identified esophageal hypersensitivity as a cause, while more non-GIs identified esophageal dysmotility and non-reflux-related esophageal conditions. As the first step, most clinicians would order investigations (70-88%). Overall, 72% would add supplemental therapy for patients with partial response, but only 58% for those with non-response. Antacid/alginate was the most common choice overall, while non-GIs were more likely to add a prokinetic than were GIs (47.8 vs. 24.1%). Approximately 40% of clinicians would switch PPIs in patients with partial response, but only 29% would do so in non-responders. Preferences for long-term therapy were highly variable. The most common initial investigation was upper endoscopy. Choice of esophageal manometry and pH monitoring was more variable, with no clear preference for whether pH monitoring should be conducted on, or off, PPI therapy. CONCLUSIONS AND INFERENCES: The survey identified a number of challenges for clinicians, especially non-GI physicians, treating patients with refractory reflux-like symptoms or rGERD on a daily basis.

Dysphagia is a common symptom with significant impact on quality of life. Our diagnostic armamentarium was primarily limited to endoscopy and barium esophagram until the advent of manometric techniques in the 1970s, which provided the first reliable tool for assessment of esophageal motor function. Since that time, significant advances have been made over the last 3 decades in our understanding of various esophageal motility disorders due to improvement in diagnostics with high-resolution esophageal manometry. High-resolution esophageal manometry has improved the sensitivity for detecting achalasia and has also enhanced our understanding of spastic and hypomotility disorders of the esophageal body. In this review, we discuss the current approach to diagnosis and therapeutics of various esophageal motility disorders.

OBJECTIVES: To review the normative data for acid, weakly acid, and nonacid proximal esophageal (PRE) and hypopharyngeal reflux (HRE) events in diagnosing laryngopharyngeal reflux (LPR) using ambulatory reflux monitoring. DATA SOURCES: PubMed, Cochrane Library, and Scopus. REVIEW METHODS: A literature search was conducted about the normative data for PRE and HRE on multichannel intraluminal impedance-pH monitoring (MII-pH), hypopharyngeal-esophageal MII-pH (HEMII-pH), or oropharyngeal pH monitoring using PICOTS (population, intervention, comparison, outcome, timing, and setting) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statements. Outcomes reviewed included device characteristics, impedance/pH sensor placements, study duration, number/average and percentiles of PRE or HRE occurrence, and the event characteristics (pH, composition, and position). RESULTS: Of 154 identified studies, 18 met criteria for analysis, including 720 healthy individuals. HEMII-pH, MII-pH, and oropharyngeal pH monitoring were used in 7, 6, and 5 studies, respectively. The definition and inclusion/exclusion criteria of healthy individuals varied substantially across studies, with 6 studies considering only digestive symptoms to exclude potential LPR patients. Substantial heterogeneity across studies was noted, including impedance/pH sensor placements/configurations and definitions of composition (liquid, gas, mixed) and type (acid, weakly acid, nonacid) of PRE/HRE. The 95th percentile thresholds were 10 to 73 events for PRE, 0 to 10 events for HRE on HEMII-pH, and 40 to 128 for events with pH <6.0 on oropharyngeal pH monitoring. Most HREs were nonacid and occurred upright. The mean HRE among healthy individuals was 1. CONCLUSION: The low number of studies and the heterogeneity in inclusion criteria, definitions, and characterization of PRE and HRE limit the establishment of consensual normative criteria for LPR on ambulatory reflux monitoring. Future large multicenter studies are needed.

Background and Aims: Helicobacter pylori eradication rates have declined as antibiotic resistance rates have increased. In addition, adherence to treatment guidelines is suboptimal. It is therefore important that contemporary, real-world evidence of diagnostic and treatment patterns is explored and compared with evidence-based guidelines. The Study of Acid-Related Disorders investigated unmet needs among patients with H pylori infection and past or current dyspepsia. Methods: Gastroenterologists (GIs) and family physicians (FPs) or general practitioners (GPs) treating patients with H pylori infection and past or current dyspepsia completed a physician survey and invited patients to complete a patient survey; data were also extracted from the medical records of enrolled patients. Results: Two hundred fifty-one physicians and 77 patients were enrolled. A total of 19.5% of patients were diagnosed by serology, whereas the urea breath test was used by 6.5% of GIs and 50.0% of FPs or GPs. A total of 68.6% of GIs and 79.8% of FPs or GPs selected clarithromycin, amoxicillin, and proton pump inhibitor triple therapy as their ideal first-line treatment. Physicians reported that 52.9% of patients experienced dyspepsia daily. A total of 46.8% of patients believed that complete resolution of dyspepsia would indicate effective treatment. As their treatment goal, 69.3% of physicians selected improvement in overall symptoms, whereas 92.2% of patients specified improvement in dyspepsia. Only 28.7% of physicians were satisfied with current treatment options. A total of 59.7% of patients took all of their prescribed medicine(s). A total of 59.7% of patients would prefer to take fewer pills; 45.5% would prefer convenience packs. Conclusion: This study reveals a lack of adherence to current H pylori guidelines for diagnosis, testing, and treatment. New treatment options that are more efficacious and simpler for patients to adhere to are needed.
RESUMEN
Gastro-oesophageal reflux disease (GERD) is a common disorder in adults and children. The global prevalence of GERD is high and increasing. Non-erosive reflux disease is the most common phenotype of GERD. Heartburn and regurgitation are considered classic symptoms but GERD may present with various atypical and extra-oesophageal manifestations. The pathophysiology of GERD is multifactorial and different mechanisms may result in GERD symptoms, including gastric composition and motility, anti-reflux barrier, refluxate characteristics, clearance mechanisms, mucosal integrity and symptom perception. In clinical practice, the diagnosis of GERD is commonly established on the basis of response to anti-reflux treatment; however, a more accurate diagnosis requires testing that includes upper gastrointestinal tract endoscopy and reflux monitoring. New techniques and new reflux testing parameters help to better phenotype the condition. In children, the diagnosis of GERD is primarily based on history and physical examination and treatment vary with age. Treatment in adults includes a combination of lifestyle modifications with pharmacological, endoscopic or surgical intervention. In refractory GERD, optimization of proton-pump inhibitor treatment should be attempted before a series of diagnostic tests to assess the patient's phenotype.

BACKGROUND: The management of achalasia has improved due to diagnostic and therapeutic innovations. However, variability in care delivery remains and no established measures defining quality of care for this population exist. We aimed to use formal methodology to establish quality indicators for achalasia patients. METHODS: Quality indicator concepts were identified from the literature, consensus guidelines and clinical experts. Using RAND/University of California, Los Angeles (UCLA) Appropriateness Method, experts in achalasia independently ranked proposed concepts in a two-round modified Delphi process based on 1) importance, 2) scientific acceptability, 3) usability, and 4) feasibility. Highly valid measures required strict agreement (⧠80% of panelists) in the range of 7-9 for across all four categories. KEY RESULTS: There were 17 experts who rated 26 proposed quality indicator topics. In round one, 2 (8%) quality measures were rated valid. In round two, 19 measures were modified based on panel suggestions, and experts rated 10 (53%) of these measures as valid, resulting in a total of 12 quality indicators. Two measures pertained to patient education and five to diagnosis, including discussing treatment options with risk and benefits and using the most recent version of the Chicago Classification to define achalasia phenotypes, respectively. Other indicators pertained to treatment options, such as the use of botulinum toxin for those not considered surgical candidates and management of reflux following achalasia treatment. CONCLUSIONS & INFERENCES: Using a robust methodology, achalasia quality indicators were identified, which can form the basis for establishing quality gaps and generating fully specified quality measures.

BACKGROUND: Proton pump inhibitors (PPIs) use is associated with hypergastrinemia and gut microbiota alteration. Concern over the risk that these factors may increase chances of colorectal cancer (CRC) has risen. To investigate the association between PPIs use and CRC using a large population-based cohort and examine whether the PPIs may differ regarding the risk of CRC. METHODS: We conducted a nationwide cohort study using a database from Taiwan National Health Insurance followed up longitudinally from 1999 through 2011. Patients with PPIs use were compared with non-use controls at a 1:1 ratio, for age, sex, comorbidities, and medications. We performed Cox proportional-hazards regression analysis to estimate the association between PPIs use and the development of CRC. RESULTS: Among the 45382 eligible PPIs users, 172 (0.4%) developed CRC during a median follow-up of 5.4 years. PPIs use was associated with a higher risk of CRC with an adjusted HR of 2.03 (95% CI 1.56-2.63, P<0.001). The risk increased with more frequent use of PPIs (HR 1.59, 95% CI 1.19-2.14; 2.59, 95% CI 1.84-3.65 and 4.33, 95% CI 2.75-6.80 for ≤30 cDDD per year, 30-90 cDDD per year, and ≥90 cDDD per year, respectively). There was also a statistically significant trend toward an increased risk with long-term PPIs use for more than one year. All PPIs, except pantoprazole and rabeprazole, were associated with an increased risk of CRC. CONCLUSIONS: The present study suggests that PPIs use might increase the risk of CRC in a dose-dependent manner.

BACKGROUND AND AIMS: Proton pump inhibitor (PPI) therapy fails to provide adequate symptom control in up to 50% of patients with gastroesophageal reflux symptoms. Although a proportion do not require ongoing PPI therapy, a diagnostic approach to identify candidates appropriate for PPI cessation is not available. This study aimed to examine the clinical utility of prolonged wireless reflux monitoring to predict the ability to discontinue PPIs. METHODS: This double-blinded clinical trial performed over 3 years at 2 centers enrolled adults with troublesome esophageal symptoms of heartburn, regurgitation, and/or chest pain and inadequate PPI response. Participants underwent prolonged wireless reflux monitoring (off PPIs for ≥7 days) and a 3-week PPI cessation intervention. Primary outcome was tolerance of PPI cessation (discontinued or resumed PPIs). Symptom burden was quantified using the Reflux Symptom Questionnaire electronic Diary (RESQ-eD). RESULTS: Of 128 enrolled, 100 participants met inclusion criteria (mean age, 48.6 years; 41 men). Thirty-four participants (34%) discontinued PPIs. The strongest predictor of PPI discontinuation was number of days with acid exposure time (AET) > 4.0% (odds ratio, 1.82; P < .001). Participants with 0 days of AET > 4.0% had a 10 times increased odds of discontinuing PPI than participants with 4 days of AET > 4.0%. Reduction in symptom burden was greater among the discontinued versus resumed PPI group (RESQ-eD, -43.7% vs -5.3%; P = .04). CONCLUSIONS: Among patients with typical reflux symptoms, inadequate PPI response, and absence of severe esophagitis, acid exposure on reflux monitoring predicted the ability to discontinue PPIs without symptom escalation. Upfront reflux monitoring off acid suppression can limit unnecessary PPI use and guide personalized management. (ClinicalTrials.gov, Number: NCT03202537).
