RESUMEN
Background/Aims: Noncardiac chest pain (NCCP) of esophageal origin is a challenging clinical problem of diverse etiology that affects more than 80 million Americans yearly. We assess the prevalence and impact of psychological disorders on NCCP of esophageal origin, describe possible mechanisms associated with this condition, and review psychological therapy options. Methods: Online search using PubMed and Medline from January 1, 1966, to April 30, 2023. Results: Psychological disorders have been reported in up to 79% of patients with NCCP of esophageal origin. Several psychological disturbances have been identified with this condition, including depression, anxiety, panic disorder, phobias, and obsessive-compulsive and somatoform disorders. It is unclear whether the psychological disorders trigger the chest pain or vice versa. Multiple psychological mechanisms have been linked to chest pain and may contribute to its pathogenesis and severity. These mechanisms include cardiophobia, poor coping strategies, negative social problem solving, stress and perceived control, hypervigilance to cardiopulmonary sensations, altered pain perception, and alexithymia. Psychological therapies for NCCP of esophageal origin include cognitive behavioral therapy, hypnotherapy, physical and relaxation training, breathing retraining, and alternative medicine. Among the therapeutic options, cognitive behavioral therapy has been shown to be an effective treatment for NCCP of esophageal origin. Conclusion: This review raises awareness about the high prevalence of psychological disorders in NCCP of esophageal origin and highlights the need for clinical trials and trained therapists to address the management of this taxing clinical problem.
RESUMEN
BACKGROUND: Diabetes Mellitus (DM) is known to induce a wide range of harmful effects on several organs, notably leading to ineffective esophageal motility (IEM). However, the relationship between DM and IEM is not fully elucidated. We aimed to determine the relationship between DM and IEM and to evaluate the impact of DM's end organ complications on IEM severity. METHODS: A multicenter cohort study of consecutive patients undergoing high-resolution esophageal manometry (HREM) was performed. We reviewed medical records of patients diagnosed with IEM using HREM, encompassing data on demographics, DM history, antidiabetic and other medications as well as comorbidities. KEY RESULTS: Two hundred and forty six subjects met the inclusion criteria. There was no significant difference in any of the HREM parameters between diabetics and nondiabetics. Out of 246 patients, 92 were diabetics. Diabetics with neuropathy presented a significantly lower distal contractile integral (DCI) value compared to those without neuropathy (248.2 ± 226.7 mmHg·cm·sec vs. 375.6 ± 232.4 mmHg·cm·sec; p = 0.02) Similarly, the DCI was lower in diabetics with retinopathy compared to those without retinopathy (199.9 ± 123.1 mmHg·cm·sec vs. 335.4 ± 251.7 mmHg·cm·sec; p = 0.041). Additionally, a significant difference was observed in DCI values among DM patients with ≥2 comorbidities compared to those without comorbidities (224.8 ± 161.0 mmHg·cm·sec vs. 394.2 ± 243.6 mmHg·cm·sec; p = 0.025). Around 12.6% of the variation in DCI could be explained by its linear relationship with hemoglobin A1c (HbA1c), with a regression coefficient (ß) of -55.3. CONCLUSION & INFERENCES: DM is significantly associated with IEM in patients with neuropathy, retinopathy, or multiple comorbidities. These results are pivotal for tailoring patient-specific management approaches.

BACKGROUD: The use of neuromodulators is prevalent in various functional gastrointestinal disease. However, data concerning the outcomes of these treatments in functional esophageal disorders (FED) remains limited and inadequate. AIMS: The aim of the present study is to examine the efficacy of central neuromodulators in FED. METHODS: We searched PubMed, EMBASE, and the Cochrane library databases from inception to April 2023. Randomized controlled trials that compared the effects of neuromodulators and placebos on FED are included. Primary outcome is the symptom improvement, and Rome IV criteria is used to assess eligible studies. RESULTS: Eleven randomized controlled studies (three for functional chest pain, four for reflux hypersensitivity/functional heartburn, three for globus, and one for functional dysphagia) were included in the final analysis. Neuromodulators reduced chest pain by 52%-71% in patients with functional chest pain, and alleviated symptom by 46%-75% in patients with globus (n = 3, Odds ratio 6.30, 95% confidence interval 4.17-9.50). However, the results were inconsistent for reflux hypersensitivity and functional heartburn. There was a lack of convincing evidence to support the use of neuromodulators for functional dysphagia. The use of neuromodulators did not have a significant impact on the quality of life. CONCLUSIONS: Functional chest pain and globus may potentially benefit from the use of neuromodulators, but their effectiveness for functional dysphagia, functional heartburn and reflux hypersensitivity remains controversial. More controlled trials are needed to confirm the therapeutic effects on these conditions.
RESUMEN
BACKGROUND & AIMS: Potassium-competitive acid blockers have documented efficacy for erosive esophagitis. We performed a randomized trial in United States subjects diagnosed with non-erosive reflux disease of vonoprazan vs placebo for 4 weeks, followed by a 20-week active-treatment extension. METHODS: Adult subjects with heartburn ≥4 days/week during screening without erosive esophagitis on endoscopy were randomized to placebo, vonoprazan 10 mg, or vonoprazan 20 mg. After 4 weeks, subjects on placebo were re-randomized to vonoprazan 10 mg or 20 mg, and those already on vonoprazan continued at the same dose for 20 weeks. Electronic diaries were completed twice daily. The primary endpoint was percentage of days without daytime or nighttime heartburn (24-hour heartburn-free days). RESULTS: Among 772 randomized subjects, the percentage of 24-hour heartburn-free days was 27.7% for placebo vs 44.8% for vonoprazan 10 mg (least squares mean difference, 17.1%; P < .0001) and 44.4% for vonoprazan 20 mg (least squares mean difference, 16.7%; P < .0001). Differences in percentage of subjects with a 24-hour heartburn-free day for vonoprazan 10 mg vs placebo and vonoprazan 20 mg vs placebo were 8.3% and 11.6% on day 1 and 18.1% and 23.2% on day 2. The mean/median percentages of 24-hour heartburn-free days over the extension period were similar across the 4 study arms: 61%-63%/76%-79%. CONCLUSIONS: Vonoprazan reduced heartburn symptoms in subjects diagnosed with non-erosive reflux disease, with the benefit appearing to begin as early as the first day of therapy. Treatment effect persisted after the initial 4-week placebo-controlled period throughout the 20-week extension period. The 2 vonoprazan doses (10 mg and 20 mg) were similar in efficacy.

RESUMEN
Importance: Surveillance for hepatocellular carcinoma (HCC) in patients with cirrhosis is underused. Identifying potentially modifiable factors to address barriers in HCC surveillance is critical to improve patient outcomes. Objective: To evaluate clinician-level factors contributing to underuse of HCC surveillance in patients with cirrhosis. Design, Setting, and Participants: This survey study included primary care clinicians (PCCs) and gastroenterology and hepatology clinicians at 5 safety-net health systems in the US. Clinicians were surveyed from March 15 to September 15, 2023, to assess knowledge, attitudes, beliefs, perceived barriers, and COVID-19-related disruptions in HCC surveillance in patients with cirrhosis. Data were analyzed from October to November 2023. Main Outcome and Measures: HCC surveillance knowledge was assessed with 6 questions querying the respondent's ability to correctly identify appropriate use of HCC surveillance. Attitudes, perceived barriers, and beliefs regarding HCC surveillance and perceived impact of the COVID-19 pandemic-related disruptions with HCC surveillance were assessed with a series of statements using a 4-point Likert scale and compared PCCs and gastroenterology and hepatology clinicians. Results: Overall, 347 of 1362 clinicians responded to the survey (25.5% response rate), among whom 142 of 237 (59.9%) were PCCs, 48 of 237 (20.3%) gastroenterology and hepatology, 190 of 236 (80.5%) were doctors of medicine and doctors of osteopathic medicine, and 46 of 236 (19.5%) were advanced practice clinicians. On HCC knowledge assessment, 144 of 270 (53.3%) scored 5 or more of 6 questions correctly, 37 of 48 (77.1%) among gastroenterology and hepatology vs 65 of 142 (45.8%) among PCCs (P < .001). Those with higher HCC knowledge scores were less likely to report barriers to HCC surveillance. PCCs were more likely to report inadequate time to discuss HCC surveillance (37 of 139 [26.6%] vs 2 of 48 [4.2%]; P = .001), difficulty identifying patients with cirrhosis (82 of 141 [58.2%] vs 5 of 48 [10.4%]; P < .001), and were not up-to-date with HCC surveillance guidelines (87 of 139 [62.6%] vs 5 of 48 [10.4%]; P < .001) compared with gastroenterology and hepatology clinicians. While most acknowledged delays during the COVID-19 pandemic, 62 of 136 PCCs (45.6%) and 27 of 45 gastroenterology and hepatology clinicians (60.0%) reported that patients with cirrhosis could currently complete HCC surveillance without delays. Conclusions and Relevance: In this survey study, important gaps in knowledge and perceived barriers to HCC surveillance were identified. Effective delivery of HCC education to PCCs and health system-level interventions must be pursued in parallel to address the complex barriers affecting suboptimal HCC surveillance in patients with cirrhosis.

BACKGROUND & AIMS: Brain-gut behavior therapies (BGBT) are increasingly recognized as effective therapeutic interventions for functional heartburn. However, recommendations regarding candidacy for treatment, initial treatment selection, and navigating treatment non-response have not been established for functional heartburn specifically. The aim of this study was to establish expert-based recommendations for behavioral treatment in patients with functional heartburn. METHODS: The validated RAND/University of California, Los Angeles Appropriateness Method was applied to develop recommendations. A 15-member panel composed of 10 gastrointestinal psychologists and 5 esophageal specialists ranked the appropriateness of a series of statements on a 9-point interval scale over 2 ranking periods. Statements were within the following domains: pre-therapy evaluation, candidacy criteria for BGBT, selection of initial BGBT, role of additional therapy for initial non-response to BGBT, and role of pharmacologic neuromodulation. The primary outcome was appropriateness of each intervention based on the recommendation statements. RESULTS: Recommendations for psychosocial assessment (eg, hypervigilance, symptom-specific anxiety, health-related quality of life), candidacy criteria (eg, motivated for BGBT, acknowledges the role of stress in symptoms), and treatment were established. Gut-directed hypnotherapy or cognitive behavioral therapy were considered appropriate BGBT for functional heartburn. Neuromodulation and/or additional BGBT were considered appropriate in the context of non-response. CONCLUSIONS: Gut-directed hypnotherapy and/or cognitive behavioral therapy are recommended as appropriate behavioral interventions for heartburn symptoms, depending on clinical indication, specific gut-brain targets, and preferred treatment modality (pharmacologic vs non-pharmacologic). Pre-therapy evaluation of psychosocial processes and candidacy for BGBT are important to determine eligibility for referral to psychogastroenterology services.

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.

BACKGROUND: Prior studies have demonstrated that obesity may be associated with the development of gastroesophageal reflux disease (GERD) and GERD-related complications. However, such association has never been assessed in a global-wide real-world patient population. METHODS: The TriNetX electronic health records network, which involves 92 healthcare organizations in 12 countries, was utilized for this multicenter global health research network study. The cohort with obesity comprised adult patients with body mass index (BMI) of more than 30 kg/m2. We performed 1:1 propensity score matching to decrease confounders effects. The prevalence of GERD and GERD-related complications including erosive esophagitis, Barrett's esophagus (BE), BE with dysplasia, and esophageal adenocarcinoma were assessed. RESULTS: A total of 2,356,548 patients were included in the obesity and non-obesity groups after propensity score matching. In the group with obesity, patients had a significantly higher prevalence of GERD (30% vs. 24%, OR 1.35, 95% CI 1.34-1.36) compared to the group without obesity. Further analysis showed a higher prevalence of GERD-related complications in the group with obesity with statistical significance: Erosive esophagitis (OR 1.07, 95% CI 1.05-1.08), Barrett's esophagus (1.08, 1.05-1.10), BE with dysplasia (1.11, 1.04-1.18), esophageal cancer (1.32, 1.15-1.51). CONCLUSION: Globally, obesity was associated with a higher prevalence of GERD and GERD-related complications.

BACKGROUND AND AIM: Up to 40% of gastroesophageal reflux disease (GERD) patients experience inadequate symptom relief with a proton pump inhibitor (PPI), termed PPI-resistant or refractory GERD. Vonoprazan, a potassium-competitive acid blocker, has better efficacy than PPI in suppressing gastric acid secretion. This meta-analysis summarizes the efficacy and safety of vonoprazan for treating PPI-resistant GERD (both erosive esophagitis [EE] and non-erosive reflux disease [NERD]). METHODS: Four electronic databases (Medline, Embase, SCOPUS, and CENTRAL) were searched for studies indexed until August 1, 2023. Both observational studies and clinical trials assessing the efficacy and safety of vonoprazan in PPI-resistant GERD were included. Efficacy outcomes included healing and maintenance rates of EE and improvement of the Frequency Scale for Symptoms of GERD (FSSG) scores. Serious adverse events (SAEs) were considered a safety outcome. The modified Newcastle-Ottawa Scale (NOS) was used to assess study quality. RESULTS: Twelve studies were included in this meta-analysis. Healing rates of PPI-resistant EE with vonoprazan 20 mg were 91.7% (95% CI 86.8-94.8%) and 88.5% (95% CI 69.7-96.2%) at weeks 4 and 8, respectively. For healed PPI-resistant EE, the overall maintenance rates with vonoprazan 10 mg were 82.6% (95% 61.2-95.0%) at week 8, 86.0% (95% CI 72.1-94.7%) at week 24, and 93.8% (95% CI 69.8-99.8%) at week 48. FSSG scores were improved in 74.6% (95% CI 65.8-81.7%) and 51.9% (95% CI 37.8-65.7%) of patients at weeks 4 and 8. Overall, no SAE was reported. CONCLUSION: Vonoprazan demonstrated high efficacy in the healing and maintenance of PPI-resistant EE and moderate efficacy for the improvement of FSSG score. Vonoprazan was well tolerated in PPI-resistant GERD patients.

Rome IV recommended esophageal biopsies in patients with dysphagia and normal endoscopy to exclude mucosal disease. Thus far, studies evaluating the utility of this recommendation remain scarce. The aims of this study were to determine the value of random esophageal biopsies in heartburn patients with dysphagia and normal endoscopy and compare the yield of random esophageal biopsies between younger versus older patients. Data were collected from consecutive patients presenting with dysphagia, 18 years and older, who were on proton pump inhibitors and had normal upper endoscopy. Biopsy results of patients with and without heartburn were recorded. Logistic regression analysis was used to compare normal versus abnormal biopsy results in younger and older patients accounting for confounding variables. The number of abnormal biopsies was significantly higher than normal biopsies (68% and 32%, respectively, P = 0.0001). Among abnormal biopsy results, microscopic gastroesophageal reflux disease was significantly more common than all other findings (39%, P = 0.0495). There was no significant difference in biopsy results in patients with and without heartburn as well as younger versus older patients (P = 0.3384, P = 0.1010, and P = 0.8468, respectively). Our study demonstrated that most patients with dysphagia and normal upper endoscopy who are on proton pump inhibitor have some type of histologic mucosal abnormality, which can direct future management. Among abnormal biopsies, microscopic reflux was by far the most common finding in patients with or without a history of heartburn. While this supports the management strategy proposed by Rome IV, age did not drive esophageal biopsy results.

BACKGROUND: Shorter half-life glucagon-like peptide-1 receptor agonists (GLP-1 RAs) delay gastric emptying (DGE) more than GLP-1 RAs with longer half-lives. DGE is a known risk factor for gastro-oesophageal reflux disease (GERD) and its complications. AIM: To determine whether short-acting or long-acting GLP-1 RAs are associated with an increased risk of new GERD or GERD-related complications DESIGN: We used the TriNetX global database to identify adult patients with type 2 diabetes mellitus and generated two cohorts totalling 1 543 351 patients on (1) GLP-1 RA or (2) other second-line diabetes medication. Using propensity-score matching, Kaplan-Meier Analysis and Cox-proportional hazards ratio (HR), we analysed outcomes and separately examined outcomes in patients starting short-acting (≤1 day) and long-acting (≥5 days) GLP-1 RAs. RESULTS: 177 666 patients were in each propensity-matched cohort. GLP-1 RA exposure was associated with an increased risk (HR 1.15; 95% CI 1.09 to 1.22) of erosive reflux disease (ERD). However, this was solely due to short-acting (HR 1.215; 95% CI 1.111 to 1.328), but not long-acting (HR 0.994; 95% CI 0.924 to 1.069) GLP-1 RA exposure. Short-acting GLP-1 RAs were also associated with increased risk of oesophageal stricture (HR 1.284; 95% CI 1.135 to 1.453), Barrett's without dysplasia (HR 1.372; 95% CI 1.217 to 1.546) and Barrett's with dysplasia (HR 1.505; 95% CI 1.164 to 1.946) whereas long-acting GLP-1 RAs were not. This association persisted in sensitivity analyses, and when individually examining the short-acting GLP-1 RAs liraglutide, lixisenatide and exenatide. CONCLUSION: Starting shorter-acting GLP-1 RAs is associated with increased risks of GERD and its complications.

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: Tetrahydrocannabinol, the main psychoactive compound in cannabis, binds with high affinity to the cannabinoid 1 receptor. Small randomized controlled studies using conventional manometry have shown that the cannabinoid 1 receptor can modulate esophageal function, namely transient lower esophageal sphincter relaxation frequency and lower esophageal sphincter tone. The effect of cannabinoids on esophageal motility in patients referred for esophageal manometry has not been fully elucidated using high-resolution esophageal manometry (HREM). We aimed to characterize the clinical effect of chronic cannabis use on esophageal motility utilizing HREM. METHODS: Patients who underwent HREM from 2009 to 2019 were identified at 4 academic medical centers. The study group consisted of patients with a noted history of chronic cannabis use, a diagnosis of cannabis-related disorder, or a positive urine toxicology screen. Age and gender-matched patients with no history of cannabis use were selected to form the control group. Data on HREM metrics based on the Chicago classification V3, and the prevalence of esophageal motility disorders were compared. Confounding effects of BMI and medications on esophageal motility were adjusted for. RESULTS: Chronic cannabis use was found to be an independent negative predictor of weak swallows (ß=-8.02, P =0.0109), but not a predictor of failed swallows ( P =0.6890). The prevalence of ineffective esophageal motility was significantly lower in chronic cannabis users compared with nonusers (OR=0.44, 95% CI 0.19-0.93, P =0.0384). There was no significant difference in the prevalence of other esophageal motility disorders between the 2 cohorts. In patients with dysphagia as their primary indication for HREM, chronic cannabis use was found to be independently associated with increased median integrated relaxation pressure (ß=6.638, P =0.0153) and increased mean lower esophageal sphincter resting pressure (ß=10.38, P =0.0084). CONCLUSIONS: Chronic cannabis use is associated with decreased weak swallows and reduced prevalence of ineffective esophageal motility in patients referred for esophageal manometry. In patients referred for dysphagia, chronic cannabis use is associated with increased integrated relaxation pressure and lower esophageal sphincter resting pressure, though not to levels above the normal range.

BACKGROUND & AIMS: Chronic pancreatitis (CP) causes an abdominal pain syndrome associated with poor quality of life. We conducted a clinical trial to further investigate the efficacy and safety of camostat, an oral serine protease inhibitor that has been used to alleviate pain in CP. METHODS: This was a double-blind randomized controlled trial that enrolled adults with CP with a baseline average daily worst pain score ≥4 on a numeric rating system. Participants were randomized (1:1:1:1) to receive camostat at 100, 200, or 300 mg 3 times daily or placebo. The primary end point was a 4-week change from baseline in the mean daily worst pain intensity score (0-10 on a numeric rating system) using a mixed model repeated measure analysis. Secondary end points included changes in alternate pain end points, quality of life, and safety. RESULTS: A total of 264 participants with CP were randomized. Changes in pain from baseline were similar between the camostat groups and placebo, with differences of least squares means of -0.11 (95% CI, -0.90 to 0.68), -0.04 (95% CI, -0.85 to 0.78), and -0.11 (95% CI, -0.94 to 0.73) for the 100 mg, 200 mg, and 300 mg groups, respectively. Multiple subgroup analyses were similar for the primary end point, and no differences were observed in any of the secondary end points. Treatment-emergent adverse events attributed to the study drug were identified in 42 participants (16.0%). CONCLUSION: We were not able to reject the null hypothesis of no difference in improvements in pain or quality of life outcomes in participants with painful CP who received camostat compared with placebo. Studies are needed to further define mechanisms of pain in CP to guide future clinical trials, including minimizing placebo responses and selecting targeted therapies.

BACKGROUND & AIMS: Metoclopramide nasal spray (MNS) was developed as an alternative to oral metoclopramide. Prior phase 2 studies demonstrated efficacy in reducing symptoms in women, but not men with diabetic gastroparesis. The aim of this phase 3 study was to further determine the safety and efficacy of MNS compared with placebo in reducing symptoms of diabetic gastroparesis in women. METHODS: This US multicenter, randomized, double-blind, parallel group study enrolled women aged 18-75 years with diabetic gastroparesis and delayed gastric emptying. Subjects were randomized 1:1 to receive placebo or MNS 10 mg. The primary efficacy end point was change in mean daily Gastroparesis Symptom Assessment total score from baseline to Week 4. The Gastroparesis Symptom Assessment daily diary is a validated patient-reported outcome instrument that averages scores of nausea, early satiety, prolonged fullness, bloating, and upper abdominal pain on a 5-point ordinal scale. RESULTS: Two hundred and five subjects were randomized to receive placebo (n = 103) or MNS (n = 102). Overall, the MNS group did not experience a significant reduction in symptoms compared with the placebo group from baseline to Week 4 (P = .881). However, subjects with moderate-to-severe symptoms at baseline had a significant treatment effect from Weeks 1 to 3 (P < .05) and experienced a significant reduction in nausea and upper abdominal pain for all 4 weeks versus placebo (P < .05). Treatment-emergent adverse events were primarily mild to moderate with headache and abdominal pain reported most frequently. CONCLUSIONS: Although the primary end point was not met using all enrolled patients, treatment with MNS provided significant relief for women with moderate-to-severe diabetic gastroparesis symptoms. MNS was well tolerated and demonstrated a similar safety profile to placebo. (ClinicalTrials.gov identifier: NCT02025725.).
RESUMEN
BACKGROUND AND AIMS: Estrogen-based therapies may increase the risk of gastroesophageal reflux (GERD) and its complications. We aimed to determine the effect of raloxifene on the development of GERD, Barrett's esophagus, and esophageal stricture in postmenopausal women with osteoporosis. METHODS: This was a population-based, propensity-matched cohort study using the TriNetX platform. Patients 50 years and older with a diagnosis of "menopause" and "osteoporosis" were included in this study. Odds ratios (OR) and 95% confidence intervals (CI) were calculated for new GERD, esophageal stricture and Barrett's esophagus after raloxifene exposure. The control cohort consisted of patients who did not start any hormonal replacement therapy. We conducted a multivariable logistic regression analysis to evaluate the effect of confounding variables and also addressed common confounding medications with 1:1 propensity score-matching. Internal validity was confirmed by comparing to negative controls (lisinopril, atorvastatin) and positive controls (metformin, ibuprofen, aspirin). RESULTS: Five thousand four hundred and seventy two postmenopausal women with osteoporosis were on raloxifene of which 1908 (34.86%) developed GERD, compared to 296,067 postmenopausal who were not on raloxifene of which 90,643 (30.62%) developed GERD (OR 1.2; 95% CI 1.10-1.31, p < 0.0001). This persisted after adjusting for common medications known to affect GERD. Raloxifene was identified as a risk factor for GERD in a multivariate analysis, controlling for factors including age, obesity, smoking, and alcohol use (OR 1.51, 95% Wald CI 1.47-1.53). Raloxifene was associated with esophageal stricture (OR 1.60; 95% Wald CI 1.51-1.69) and Barrett's esophagus (OR 1.50; 95% Wald CI 1.37-1.63) in multivariate analysis. These associations persisted using sensitivity analyses. CONCLUSION: Raloxifene increases the risk of GERD, esophageal stricture and Barrett's esophagus in postmenopausal women with osteoporosis. Further studies are needed to confirm our findings.

In general, gastroesophageal reflux disease (GERD) is diagnosed clinically based on typical symptoms and/or response to proton pump inhibitor treatment. Upper gastrointestinal endoscopy is reserved for patients presenting with alarm symptoms, such as dysphagia, odynophagia, significant weight loss, gastrointestinal bleeding, or anorexia; those who meet the criteria for Barrett's esophagus screening; those who report a lack or partial response to proton pump inhibitor treatment; and those with prior endoscopic or surgical anti-reflux interventions. Newer endoscopic techniques are primarily used to increase diagnostic yield and provide an alternative to medical or surgical treatment for GERD. The available endoscopic modalities for the diagnosis of GERD include conventional endoscopy with white-light imaging, high-resolution and high-magnification endoscopy, chromoendoscopy, image-enhanced endoscopy (narrow-band imaging, I- SCAN, flexible spectral imaging color enhancement, blue laser imaging, and linked color imaging), and confocal laser endomicroscopy. Endoscopic techniques for treating GERD include esophageal radiofrequency energy delivery/Stretta procedure, transoral incisionless fundoplication, and endoscopic full-thickness plication. Other novel techniques include anti-reflux mucosectomy, peroral endoscopic cardiac constriction, endoscopic submucosal dissection, and endoscopic band ligation. Currently, many of the new endoscopic techniques are not widely available, and their use is limited to centers of excellence.
RESUMEN
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.

Background/Aims: Multiple sclerosis (MS) is an inflammatory disease characterized by the demyelination of primarily the central nervous system. Diffuse esophageal spasm (DES) and achalasia are both disorders of esophageal peristalsis which cause clinical symptoms of dysphagia. Mechanisms involving dysfunction of the pre- and post-ganglionic nerve fibers of the myenteric plexus have been proposed. We sought to determine whether MS confers an increased risk of developing achalasia or DES. Methods: Cohort analysis was done using the Explorys database. Univariate logistic regression was performed to determine the odds MS confers to each motility disorder studied. Comparison of proportions of dysautonomia comorbidities was performed among the cohorts. Patients with a prior diagnosis of diabetes mellitus, chronic Chagas' disease, opioid use, or CREST syndrome were excluded from the study. Results: Odds of MS patients developing achalasia or DES were (OR, 2.09; 95% CI, 1.73-2.52; P < 0.001) and (OR, 3.15; 95% CI, 2.89-3.42; P < 0.001), respectively. In the MS/achalasia cohort, 27.27%, 18.18%, 9.09%, and 45.45% patients had urinary incontinence, gastroparesis, impotence, and insomnia, respectively. In the MS/DES cohort, 35.19%, 11.11%, 3.70%, and 55.56% had these symptoms. In MS patients without motility disorders, 12.64%, 0.79%, 2.21%, and 21.85% had these symptoms. Conclusions: Patients with MS have higher odds of developing achalasia or DES compared to patients without MS. MS patients with achalasia or DES have higher rates of dysautonomia comorbidities. This suggests that these patients have a more severe disease phenotype in regards to the extent of neuronal degradation and demyelination causing the autonomic dysfunction.
