Coeliac disease is a strong risk factor for Gastro-oesophageal reflux disease while a gluten free diet is protective: a systematic review and meta-analysis. EClinicalMedicine 2024; 71:102577. [PMID: 38659976 PMCID: PMC11039972 DOI: 10.1016/j.eclinm.2024.102577] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/03/2023] [Revised: 03/14/2024] [Accepted: 03/18/2024] [Indexed: 04/26/2024] Open
Abstract
Background Gastro-oesophageal reflux disease (GORD) mechanisms are well described, but the aetiology is uncertain. Coeliac disease (CD), a gluten enteropathy with increased duodenal eosinophils overlaps with GORD. Functional dyspepsia is a condition where duodenal eosinophilia is featured, and a 6-fold increased risk of incident GORD has been observed. Perturbations of the duodenum can alter proximal gastric and oesophageal motor function. We performed a systematic review and meta-analysis assessing the association between CD and GORD. Methods A systematic search of studies reporting the association of GORD and CD was conducted. CD was defined by combined serological and histological parameters. GORD was defined based on classical symptoms, oesophagitis (endoscopic or histologic) or abnormal 24-h pH monitoring; studies reporting oesophageal motility abnormalities linked with GORD were also included. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated using a random-effects model. Findings 31 papers were included. Individuals with CD on a gluten containing diet were 3 times more likely to have GORD than controls (OR: 3.37, 95% CI: 2.09-5.44), and over 10 times more likely when compared to those on a gluten free diet (GFD) (OR: 10.20, 95% CI: 6.49-16.04). Endoscopic oesophagitis was significantly associated with CD (OR: 4.96; 95% CI: 2.22-11.06). One year of a GFD in CD and GORD was more efficacious in preventing GORD symptom relapse than treatment with 8 weeks of PPI in non-CD GORD patients (OR: 0.18, 95% CI: 0.08-0.36). Paediatric CD patients were more likely to develop GORD (OR: 3.29, 95% CI: 1.46-7.43), compared to adult CD patients (OR: 2.55, 95% CI: 1.65-3.93). Interpretation CD is strongly associated with GORD but there was high heterogeneity. More convincingly, a GFD substantially improves GORD symptoms, suggesting a role for duodenal inflammation and dietary antigens in the aetiology of a subset with GORD. Ruling out CD in patients with GORD may be beneficial. Funding The study was supported by an Investigator Grant from the NHMRC to Dr. Talley.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) is very prevalent in the general population, with a broad spectrum of clinical manifestations, requiring accurate diagnosis and treatment. AIM The aim of this expert review is to establish good clinical practice recommendations for the diagnosis and personalized treatment of GERD. METHODS The good clinical practice recommendations were produced by a group of experts in GERD, members of the Asociación Mexicana de Gastroenterología (AMG), after carrying out an extensive review of the published literature and discussing each recommendation at a face-to-face meeting. This document does not aim to be a clinical practice guideline with the methodology such a document requires. RESULTS Fifteen experts on GERD formulated 27 good clinical practice recommendations for recognizing the symptoms and complications of GERD, the rational use of diagnostic tests and medical treatment, the identification and management of refractory GERD, the overlap with functional disorders, endoscopic and surgical treatment, and GERD in the pregnant woman, older adult, and the obese patient. CONCLUSIONS An accurate diagnosis of GERD is currently possible, enabling the prescription of a personalized treatment in patients with this condition. The goal of the good clinical practice recommendations by the group of experts from the AMG presented in this document is to aid both the general practitioner and specialist in the process of accurate diagnosis and treatment, in the patient with GERD.

Abstract
INTRODUCTION An association between gastroesophageal reflux disease (GERD) and common psychiatric conditions, most notably anxiety and depression, has been reported. However, the magnitude of this association is poorly understood. Therefore, we aimed to systematically assess this issue. METHODS We comprehensively searched multiple bibliographic databases (Embase, PubMed, Scopus, and Web of Science) from inception to May 15, 2023. We retrieved observational studies that reported the prevalence of anxiety and/or depressive symptoms diagnosed by validated questionnaires in ≥100 adults (aged 18 years or older) with GERD. We also included cohort studies that explored the risk of incident GERD in subjects with anxiety/depression vice versa scenario. Finally, we included Mendelian randomization studies that assessed the cause-and-effect relationship between anxiety/depression and GERD. The extracted data were combined using a random-effects model. RESULTS In total, 36 eligible studies were included. The pooled prevalences of anxiety and depressive symptoms were 34.4% (95% confidence interval [CI] 24.7-44.2; I2 = 99.4%) and 24.2% (95% CI 19.9-28.5; I2 = 98.8%) in subjects with GERD based on 30 studies, respectively. Both anxiety and depressive symptoms were more common in subjects with GERD compared with those in healthy controls (odds ratio = 4.46 [95% CI 1.94-10.25] and odds ratio = 2.56 [95% CI 1.11-5.87], respectively). According to 3 cohort studies, subjects with GERD were at an increased risk of developing anxiety/depression and vice versa. Finally, 3 Mendelian randomization studies showed that genetic liability to these mood disorders is linked to an increased risk of developing GERD and vice versa. DISCUSSION Up to 1 in 3 subjects with GERD experience anxiety and depression. There is likely a bidirectional causal relationship between anxiety/depression and GERD.

Abstract
INTRODUCTION AND AIM The gastric mucosa has been studied since the pre-Helicobacter pylori (H. pylori) era, but the complete descriptions of the stomach and duodenum have been anecdotal, and those of the distal duodenum, exceptional. Our aim was to evaluate the different epidemiologic characteristics and the gastroduodenal inflammatory status in patients with upper gastrointestinal symptoms. MATERIALS AND METHODS We studied 138 patients divided into: the non-ulcer group (functional dyspepsia [n = 77] and GERD [n = 27]) and the ulcer group (peptic ulcer [n = 13] and duodenal ulcer [n = 21]). Ten biopsy samples (2 from the corpus, 3 from the antrum, 3 from the proximal duodenum, and 2 from the distal duodenum) were taken in each patient for histologic and/or microbiologic study. RESULTS The prevalence of dyspepsia, functional dyspepsia, and H. pylori was 80.4%, 69.4%, and 82.6%, respectively. The frequency of superficial chronic gastritis in the corpus was significantly higher in the ulcer group vs. the non-ulcer group, whereas there was more chronic atrophic gastritis in the antrum in the ulcer group (P < 0.05). Duodenitis was significantly more frequent in the ulcer group vs. the non-ulcer group, in both the proximal and distal duodenum. Pangastroduodenitis was a significant finding in the ulcer group. In both groups, chronic gastritis (corpus and antrum) and duodenitis (proximal and distal) were significantly related to the presence of H. pylori. Proximal duodenitis is not an uncommon finding in functional dyspepsia (37.7%) and is twice as frequent as distal duodenitis (16.9%). CONCLUSIONS The ulcer group presented with a gastroduodenal inflammatory map different from that of the non-ulcer group and was characterized by a higher frequency of superficial chronic gastritis in the corpus, chronic atrophic gastritis in the antrum, and a very high frequency of proximal duodenitis.

Abstract
Background: Frequently, the community pharmacies are the only points of consultation for upper-gastrointestinal symptomology. However, the heterogeneity of symptoms often limits the correct management of the patient. The study aim is to describe the epidemiological and clinical characteristics of patients with upper-gastrointestinal symptoms who ask for advice in community pharmacies. Methods: A cross-sectional study was performed in 134 Spanish pharmacies (June-October 2022) and we included 1,360 patients. We collected sociodemographic, clinical variables and current medication data. The pharmacist evaluated the gastrointestinal symptoms through the application of the GERD Impact Scale (GIS questionnaire). Patients were classified into three groups according to their symptoms: epigastric, retrosternal and overlapping symptoms. Results: Median age was 49 years (interquartile range 36-62 years) and 59.3% were women. Most patients reported overlapping symptoms (738%, 54.3%), 433 (31.8%) retrosternal and 189 (13.9%) epigastric symptoms. Patients with overlapping symptoms were more likely to associated consumption of foods and/or drinks and symptoms and showed lower scores on the GIS scale (median 26, IQR 20-30) than those with epigastric (median 32, IQR 29-33) and retrosternal (median 32, IQR 28-34) symptoms (p < 0.001). Patients in treatment with a combination of alginates and antiacids were more likely to think that it better alleviated their symptoms in all the patients included (p = 0.012). Conclusion: More than half of the patients showed overlapping symptoms and were more likely to associate their symptoms with dietary habits and having poorer scores in the GIS scale. Clinical awareness of such overlapping condition would help optimize the management of patients with upper gastrointestinal symptoms in practice.

Abstract
Disorders of gut-brain interaction (DGBI) are frequently encountered in clinical practice, and recommendations for diagnosis and management are well established. In a large subset of patients, more than one DGBI diagnosis is present. This group of patients with more than one DGBI diagnosis have higher symptom severity and impact than patients with only one DGBI diagnosis, and the management approach is not well established for those with overlapping diagnoses. This Review aims to guide clinicians to understand, recognise, and manage overlapping DGBI by identifying causes and pitfalls of overlap conditions, and presenting potential practical approaches to diagnosis, treatment, and follow-up. Several clinical factors can contribute to finding overlapping DGBI, including the anatomical basis of the Rome diagnostic criteria, the potential confusion of symptom descriptors, and patients' biases towards higher symptom intensity ratings. Overlapping DGBI could also be caused by mechanistic factors such as pathophysiological mechanisms involving multiple gastrointestinal segments, and the effect of disorders in one segment on sensorimotor function in remote gastrointestinal parts, through neural or hormonal signalling. Key initial steps in the management of overlapping DGBI are detailed history taking, which can be facilitated using pictograms; carefully assessing the relative timing and cohesion of different symptoms; and recognising associated psychosocial dysfunction. Unnecessary technical investigations and complex combination treatment schedules should be avoided. Based on the identification of the dominant symptom pattern and putative underlying pathophysiological mechanisms, a single treatment modality should preferably be initiated, considering the efficacy spectrum of different therapies. Follow-up of the patient's condition allows the therapeutic approach to be adjusted as needed, while avoiding unnecessary additional technical investigations.

Abstract
Contemporary systems for the diagnosis and management gastrointestinal symptoms not attributable to organic diseases (Functional GI Disorders, FGID, now renamed Disorders of Gut-Brain Interaction, DGBI) seek to categorize patients into narrowly defined symptom-based sub-classes to enable targeted treatment of patient cohorts with similar underlying putative pathophysiology. However, an overlap of symptom categories frequently occurs and has a negative impact on treatment outcomes. There is a lack of guidance on their management. An Asian Pacific Association of Gastroenterology (APAGE) working group was set up to develop clinical practice guidelines for management of patients with functional dyspepsia (FD) who have an overlap with another functional gastrointestinal disorder: FD with gastroesophageal reflux (FD-GERD), epigastric pain syndrome with irritable bowel syndrome (EPS-IBS), postprandial distress syndrome with IBS (PDS-IBS), and FD-Constipation. We identified putative pathophysiology to provide a basis for treatment recommendations. A management algorithm is presented to guide primary and secondary care clinicians.

Abstract
Swallowing impairment is a highly prevalent and clinically significant problem affecting people and dogs. There are myriad causes of swallowing impairment of which gastroesophageal reflux is the most common in both species. Similarities in anatomy and physiology between humans and canines results in analogous swallowing disorders including cricopharyngeus muscle achalasia, esophageal achalasia, hiatal herniation, and gastroesophageal reflux with secondary esophagitis and esophageal dysmotility. Accordingly, the diagnostic approach to human and canine patients with swallowing impairment is similar. Diagnostic procedures such as swallowing fluoroscopy, high-resolution manometry, pH/impedance monitoring, and endolumenal functional luminal imaging probe can be performed in both species; however, nasofacial conformation, increased esophageal length, and the difficulty of completing several of these procedures in awake dogs are inherent challenges that need to be considered. Human patients can convey their symptoms and respond to verbal cues, whereas veterinarians must rely on clinical histories narrated by pet owners followed by comprehensive physical examination and observation of the animal eating different food consistencies and drinking water. Dogs may also be unwilling to drink or eat in the hospital setting and may be resistant to physical restraint during diagnostic procedures. Despite the species differences and diagnostic challenges, dogs are a natural animal model for many oropharyngeal and esophageal disorders affecting people, which presents a tremendous opportunity for shared learnings. This manuscript reviews the comparative aspects of esophageal anatomy and physiology between humans and canines, summarizes the diagnostic assessment of swallowing impairment in both species, and discusses future considerations for collaborative medicine and translational research.

Abstract
Aim To assess (1) the overlap rate of gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) and (2) the yield of esophagogastroduodenoscopy in patients clinically presenting with FD. Materials and Methods Outpatients aged ≥18 years with typical reflux symptoms ≥2 times a week or clinically fulfilling the Rome IV criteria for FD were recruited and underwent esophagogastroduodenoscopy. GERD was classified into non-erosive reflux disease (NERD) and erosive reflux disease (ERD), and FD was classified into epigastric pain syndrome and postprandial distress syndrome. The endoscopic findings that could explain patients’ symptoms were considered clinically significant endoscopic findings. After esophagogastroduodenoscopy, patients were categorized into three groups: GERD-only, FD-only, and GERD-FD overlap. Results There were 439 patients with a mean age of 42.3 ± 11.6 years. Ninety-one (20.7%) patients had clinically significant endoscopic findings: 73 (16.6%) reflux esophagitis, 6 (1.4%) Barrett’s esophagus and 14 (3.2%) gastroduodenal ulcers. After excluding gastroduodenal ulcers, the numbers of patients with GERD-only, FD-only, and GERD-FD overlap were 69 (16.2%), 138 (32.5%), and 218 (51.3%), respectively. Postprandial distress syndrome was more prevalent in GERD-FD overlap than in FD-only (72.9 vs. 44.2%, p < 0.001). The rates of gastroduodenal ulcers in patients clinically fulfilling the criteria for FD with and without reflux symptoms were 0.6 and 4.7%, respectively (p = 0.027). Conclusion The GERD-FD overlap was more common than each disorder alone, of which postprandial distress syndrome was significantly prominent. Organic dyspepsia was uncommon in patients clinically fulfilling the Rome IV criteria for FD.

Abstract
Gastroesophageal reflux (GOR) is defined as "the passage of gastric contents into the esophagus with or without regurgitation and vomiting" and gastroesophageal reflux disease (GORD) is defined "when GOR leads to troublesome symptoms affecting the daily functioning and/or complications." This definition was first developed in 2006 by the Montreal consensus group (1) and later on adopted by pediatric gastroenterology societies such as ESPGHAN and NASPGHAN in 2009 (2). The definition of gastroesophageal reflux reveals little about its pathophysiology and is focused on symptomatology. In this way, it acts as an umbrella term for the multifactorial causes of the disease and the various phenotypes encountered; from functional heartburn to hypersensitive esophagus and nonerosive reflux disease, to erosive esophagitis and Barrett's esophagus. This article is devoted to the pathophysiology of pediatric GORD in comparison to adult GORD and is divided in 2 parts. In the first part, we will systematically describe the different mechanisms for the generation and clearance of reflux events, while on the second part we will discuss the mechanisms involved in symptoms generation. Finally, we will discuss the similarities and differences between pediatric and adult GORD.

Abstract
BACKGROUND To evaluate the impact of laparoscopic sleeve gastrectomy (LSG) and gastric bypass (LGB) on gastroesophageal reflux disease (GERD). METHODS GERD was evaluated by the Modified Italian Gastroesophageal reflux disease-Health-Related Quality of Life (MI-GERD-HRQL) questionnaire, pH-manometry, endoscopy, and Rx-esophagogram, before and 12 months after surgery. Based on these exams, patients without GERD underwent LSG, and patients with GERD underwent LGB. RESULTS Thirteen and six patients underwent LSG and LGB, respectively. After LSG, the only statistically significant difference observed at pH-manometry was the median DeMeester score, from 5.7 to 22.7 (P = .0026). De novo GERD occurred in 6 patients (46.2%), with erosive esophagitis in one. The median MI-GERD-HRQL score improved from 3 to 0. Overall, nine patients underwent LGB, but three were lost to follow-up. Preoperative pH-manometry changed the surgical indication from LSG to LGB in 7 out of 9 patients (77.8%). Six patients who underwent LGB completed the study, and at pH-manometry, statistically significant differences were observed in the percentage of total acid exposure time, with the number of reflux episodes lasting >5 minutes and DeMeester score (P = .009). The median MI-GERD-HRQL score improved from 6.5 to 0. Statistically significant differences were not observed at endoscopy and Rx-esophagogram findings in both groups. CONCLUSIONS LSG has a negative impact on GERD, even in patients without preoperative GERD. LGB confirmed to be the intervention of choice in patients with GERD. Preoperative pH-manometry may identify patients with silent GERD, to candidate them to LGB rather than LSG. pH-manometry should be used more liberally to establish the correct surgical indication on objective grounds.

Phytother Res 2021; 36:686-704. [PMID: 34851546 DOI: 10.1002/ptr.7333] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2021] [Revised: 09/20/2021] [Accepted: 10/23/2021] [Indexed: 02/05/2023]
Abstract
Functional dyspepsia (FD) is a very common condition globally. Relevant keywords were searched for in title and abstract of selected databases, that is, Medline/PubMed, Scopus, Embase, Web of knowledge, and Google Scholar. Placebo and active-control trials on herbal remedies amongst adults who were diagnosed with FD were included. Dichotomous outcomes were presented as relative risk (RR) with 95% confidence interval (CI) and continuous outcomes were presented as pooled standardized mean difference (SMD) with 95% CI. Forty-nine randomized controlled trials (RCTs) were entered into meta-analysis (6,987 subjects). Herbal remedies resulted in a higher improvement in FD symptoms in comparison with the placebo (SMD = -0.58 [-0.66- -0.51], p < .00001 and RR = 1.73 [1.62-1.85], p < .00001). No significant difference between herbal remedies and placebo in the incidence of adverse events was observed (12.27 vs. 8.41%, RR = 1.06 [0.91-1.23], p = .45). Also, herbal remedies resulted in a higher improvement in quality of life in comparison with placebo (SMD = -0.64 [-0.73- -0.55], p < .00001). When comparing herbal remedies with conventional medicine through sensitivity analysis, no outcomes were significantly different (p > .05). Herbal remedies might be efficacious and safe in treating FD, and demonstrate comparable effect sizes for efficacy to conventional treatments. Further high-quality studies are warranted to firmly establish the clinical efficacy of the herbal remedies.

Abstract
Background Although some kinds of endoluminal surgery for patients with proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD) have been reported, there are few reports on their long-term outcomes. In 2014, we reported the effectiveness of endoscopic surgery for PPI-refractory GERD, which we invented and named endoscopic submucosal dissection for GERD (ESD-G) in 2008. Thereafter, we accumulated more cases and monitored the patients’ condition postoperatively and describe the outcomes herein. Patients and methods This single-center, single-arm trial was conducted at the Osaka Medical and Pharmaceutical University Hospital. We compared outcomes between before and 3–6 months after ESD-G. Additionally, we investigated the outcomes of patients 5 or more years after ESD-G. Results We performed 42 ESD-G procedures in 35 patients between 2008 and 2020. In seven patients, ESD-G was performed twice for various reasons. The frequency scale for the symptoms of GERD score was significantly improved 3–6 months after ESD-G (22 → 10, p < 0.0001); the Los Angeles classification for reflux esophagitis was clearly improved after ESD-G (p = 0.0423). The number of reflux episodes was not decreased by ESD-G. There was a significant difference in the potency unit of gastric acid secretion suppressants for controlling GERD-related symptoms between baseline and 3–6 months after ESD-G (p = 0.0009). In patients without a history of distal gastrectomy who underwent ESD-G, the potency unit of gastric acid secretion suppressants significantly decreased 5 or more years after ESD-G (p = 0.0121). Conclusion ESD-G may be effective in patients with refractory GERD-related symptoms without a history of distal gastrectomy.

Abstract
The study of the interaction between gastrointestinal (GI) function and psychological features is a complex and developing field. The bidirectional communication between the gut and the brain or gut-brain axis is considered as a pivotal player in the pathogenesis of the highly prevalent functional GI disorders, including irritable bowel syndrome and functional dyspepsia (FD), which have been redefined as disorders of gut-brain interaction. However, the mechanisms through which changes in the gut alter brain functioning, feelings, and behavior remain unclear. Based on the presence of duodenal pathology in adult FD patients, Ronkainen et al. provide the first prospective evidence for duodenal eosinophils potentially driving anxiety. Also in this edition, associations between gastroduodenal pathology and rumination syndrome, which may coexist with FD, have now been confirmed in children by Friesen et al. Together these findings confirm not only the potential role of duodenal alterations in determining overlapping upper GI but also psychological symptoms, which result from bidirectional and complex interactions. In this review, we provide an overview of the recent advances in this field and highlight the novel contributions of the original studies of Ronkainen et al. and Friesen et al. to this topic.

Lee KJ. The Usefulness of Symptom-based Subtypes of Functional Dyspepsia for Predicting Underlying Pathophysiologic Mechanisms and Choosing Appropriate Therapeutic Agents. J Neurogastroenterol Motil 2021; 27:326-336.

Abstract
Functional dyspepsia (FD) is considered to be a heterogeneous disorder with different pathophysiological mechanisms or pathogenetic factors. In addition to traditional mechanisms, novel concepts regarding pathophysiologic mechanisms of FD have been proposed. Candidates of therapeutic agents based on novel concepts have also been suggested. FD is a symptom complex and currently diagnosed by symptom-based Rome criteria. In the Rome criteria, symptom-based subtypes of FD including postprandial distress syndrome and epigastric pain syndrome are recommended to be used, based on the assumption that each subtype is more homogenous in terms of underlying pathophysiologic mechanisms than FD as a whole. In this review, the usefulness of symptombased subtypes of FD for predicting underlying pathophysiologic mechanisms and choosing appropriate therapeutic agents was evaluated. Although several classic pathophysiologic mechanisms are suggested to be associated with individual dyspeptic symptoms, symptom-based subtypes of FD are not specific for a certain pathogenetic factor or pathophysiologic mechanism, and may be frequently associated with multiple pathophysiologic abnormalities. Novel concepts on the pathophysiology of FD show complex interactions between pathophysiologic mechanisms and pathogenetic factors, and prediction of underlying mechanisms of individual patients simply by the symptom pattern or symptom-based subtypes may not be accurate in a considerable proportion of cases. Therefore, subtyping by the Rome criteria appears to have limited value to guide therapeutic strategy, suggesting that the addition of objective parameters or subclassification reflecting physiologic or pathologic tests may be necessary for the targeted therapeutic approaches, particularly when therapeutic agents targeting novel mechanisms are available.

Abstract
BACKGROUND Administration of a bitter compound can alter the intragastric pressure (IGP) after a meal. Additionally, a negative correlation between IGP and the number of transient lower esophageal sphincter relaxations (TLESRs) has been demonstrated. However, the effect of a bitter tastant on the number of TLESRs and subsequent reflux episodes has never been investigated and it is unclear whether bitter food items should be avoided in gastro-esophageal reflux disease. We hypothesize that bitter administration in healthy volunteers (HVs) will lead to an increase in the number of TLESRs. METHODS After an overnight fast, 20 female HVs (36 years [21-63]) underwent a high-resolution impedance manometry (HRiM) measurement. After placement of the HRiM probe, 0.1 ml/kg of a 10 mM denatonium benzoate solution (bitter) or an identical volume of water (placebo) was administered directly into the stomach. The number of TLESRs and reflux episodes was quantified 30 min before and 2 h after consumption of a high caloric meal. KEY RESULTS There was no significant difference in the number of TLESRs or reflux episodes between the bitter and placebo condition. Additionally, no differences were observed in the nature (gas or liquid) and extent of reflux events. Lower esophageal sphincter pressures dropped significantly in the first postprandial hour to start recovering slowly back to baseline values during the second postprandial hour (p < 0.0001), without any difference between both conditions. CONCLUSIONS & INTERFERENCES Administration of the bitter tastant denatonium benzoate has no influence on the number of TLESRs or reflux episodes.

Integrative Effects and Vagal Mechanisms of Transcutaneous Electrical Acustimulation on Gastroesophageal Motility in Patients With Gastroesophageal Reflux Disease. Am J Gastroenterol 2021; 116:1495-1505.

Abstract
INTRODUCTION Impaired esophageal and gastric motilities are known to contribute to symptoms of gastroesophageal reflux disease (GERD). However, there is a lack of GERD therapy, targeting both gastric and esophageal functions. This study was designed to investigate the effects of transcutaneous electrical acustimulation (TEA) on symptoms of GERD and gastroesophageal functions and possible mechanisms in patients with GERD. METHODS Thirty patients with GERD with ineffective esophageal motility were equally divided and randomized into a 4-week sham-TEA or 4-week TEA treatment. The GERD questionnaire (GerdQ), GERD health-related quality-of-life questionnaire, high-resolution esophageal manometry, a nutrient drink test, the electrogastrogram, and ECG were performed to assess the severity of reflux symptoms, low esophageal sphincter (LES) pressure, distal contractile integral (DCI), gastric accommodation, gastric slow waves (GSW), and autonomic functions, respectively. RESULTS Compared with sham-TEA, the 4-week TEA treatment significantly decreased the GerdQ score (P = 0.011) and GERD health-related quality of life (P = 0.028) and improved nutrient drink-induced fullness (P < 0.001) and belching (P < 0.001) in patients with GERD. Although only acute TEA significantly enhanced LES pressure (P < 0.05), both acute and chronic TEA remarkedly increased DCI (P < 0.05) and reduced the incidence of ineffective esophageal contractions during wet swallows (P = 0.02). In addition, chronic TEA significantly increased gastric accommodation and the percentage of postprandial normal GSW compared with sham-TEA and baseline. Concurrently, TEA-enhanced vagal activity (P = 0.02) and the vagal activity positively correlated with LES pressure (r = 0.528; P = 0.003) and DCI (r = 0.522; P = 0.003). DISCUSSION The TEA treatment performed in this study improves reflux-related symptoms, increases DCI, reduces the incidence of ineffective esophageal contractions during wet swallows, and improves gastric accommodation and slow waves. The improvement in GERD symptoms might be attributed to the integrative effects of TEA on these gastroesophageal functions mediated via the vagal mechanism.

Acute Effects of Red Chili, a Natural Capsaicin Receptor Agonist, on Gastric Accommodation and Upper Gastrointestinal Symptoms in Healthy Volunteers and Gastroesophageal Reflux Disease Patients. Nutrients 2020; 12:nu12123740.

Abstract
The effects of chili on gastric accommodation (GA) in gastroesophageal reflux disease (GERD) patients have not been explored. Methods: In total, 15 healthy volunteers (HV) and 15 pH-positive non-erosive GERD (NERD) patients underwent single-photon emission computed tomography after ingesting 2 g of chili or placebo in capsules in a randomized double-blind crossover fashion with a one-week washout period. GA was the maximal postprandial gastric volume (GV) after 250 mL of Ensure® minus the fasting GV. Upper gastrointestinal symptoms were evaluated by using a visual analog scale. Results: NERD patients but not HV had significantly greater GA after chili compared to a placebo (451 ± 89 vs. 375 ± 81 mL, p < 0.05). After chili, the postprandial GVs at 10, 20, and 30 min in NERD patients were significantly greater than HV (10 min, 600 ± 73 vs. 526 ± 70 mL; 20 min, 576 ± 81 vs. 492 ± 78 mL; 30 min, 532 ± 81 vs. 466 ± 86 mL, all p < 0.05). In NERD, chili was associated with significantly less satiety, more severe abdominal burning (p < 0.05), and a trend of more severe heartburn (p = 0.06) compared to the placebo. In HV, postprandial symptoms after chili and placebo ingestion were similar (p > 0.05). Conclusions: Chili enhanced GA in NERD patients but not in HV. This suggests that the modulation of GA in NERD is abnormal and likely involves transient receptor potential vanilloid 1 (TRPV1) sensitive pathways.

Abstract
Gastroesophageal reflux disease (GERD), a prevalent problem among obese individuals, is strongly associated with obesity and weight loss. Hence, bariatric surgery effectively improves GERD for many patients. Depending on the type of bariatric procedure, however, surgery can also worsen or even cause a new onset of GERD. As a consequence, GERD remains a relevant problem for many bariatric patients, and especially those who have undergone sleeve gastrectomy (SG). Affected patients report not only a decrease in physical functioning but also suffer from mental and emotional problems, resulting in poorer social functioning. The pathomechanism of GERD after SG is most likely multifactorial and triggered by the interaction of anatomical, physiological, and physical factors. Contributing factors include the shape of the sleeve, the extent of injury to the lower esophageal sphincter, and the presence of hiatal hernia. In order to successfully treat post-sleeve gastrectomy GERD, the cause of the problem must first be identified. Therapeutic approaches include lifestyle changes, medication, interventional treatment, and/or revisional surgery.

Gastroesophageal Reflux Disease-Functional Dyspepsia Overlap: Do Birds of a Feather Flock Together? Am J Gastroenterol 2020; 115:1167-1182.

Abstract
INTRODUCTION Gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) are 2 of the most prevalent upper gastrointestinal (GI) disorders in the Western world. Previous Rome definitions excluded patients with predominant heartburn from the definition of FD because they were considered to have GERD. However, more recent studies showed that heartburn and acid regurgitation are also common symptoms in patients with FD. The aim of this study is to provide an overview of the prevalence of overlap between GERD and FD, the underlying pathophysiology and implications for treatment. METHODS A review of the literature was performed using the PubMed database, and a meta-analysis with random effects model was completed. RESULTS This review showed considerable overlap between GERD and FD. A meta-analysis on the data included in this review showed 7.41% (confidence interval [CI]: 4.55%-11.84%) GERD/FD overlap in the general population, 41.15% (CI: 29.46%-53.93%) GERD with FD symptoms, and 31.32% (CI: 19.43%-46.29%) FD with GERD symptoms. Although numerous committees and consensus groups attempted to develop uniform definitions for the diagnosis of GERD and FD, various diagnostic criteria are used across studies and clinical trials (frequency, severity, and location of symptoms). Several studies showed that the overlap between GERD and FD can be explained by a shared pathophysiology, including delayed gastric emptying and disturbed gastric accommodation. DISCUSSION For diagnoses of GERD and FD, uniform definitions that are easy to implement in population studies, easy to interpret for physicians, and that need to be well explained to patients to avoid overestimation or underestimation of true prevalence are needed. Both GERD and FD coexist more frequently than expected, based on coincidence, suggesting a potential pathophysiological link. More research is needed to explore the common GERD/FD overlap population to identify the underlying pathophysiological mechanisms, which may lead to a more effective therapeutic approach.

Abstract
Gastroesophageal reflux (GER) is considered physiologic and is a normal process; whereas, when aerodigestive consequences are associated, it is often interpreted as GER disease (GERD). However, the distinction between them remains a challenge in infants in the NICU. Reflux-type of symptoms are heterogeneous, and often managed with changes in diet, feeding methods, and acid-suppressive therapy; all these empiric therapies lack objectivity; hence, practice variation is universal. We clarify the current controversies, explain the potential role of GERD in causing symptoms and complications, and highlight current advances. The evidence basis for the diagnostic strategies is discussed.

Abstract
Gastroesophageal reflux (GER) describes a process in which gastric contents travel retrograde into the esophagus. GER can be either a physiologic phenomenon that occurs in asymptomatic individuals or can potentially cause symptoms. When the latter occurs, this represents GER disease (GERD). The process by which GER transforms into GERD begins at the esophagogastric junction. Impaired clearance of the refluxate also contributes to GERD. Reflux causes degradation of esophageal mucosal defense. The refluxate triggers sensory afferents leading to symptom generation.

Abstract
Emerging data increasingly point towards the duodenum as a key region underlying the pathophysiology of functional dyspepsia (FD), one of the most prevalent functional GI disorders. The duodenum plays a major role in the control and coordination of gastroduodenal function. Impaired duodenal mucosal integrity and low-grade inflammation have been associated with altered neuronal signalling and systemic immune activation, and these alterations may ultimately lead to dyspeptic symptoms. Likely luminal candidates inducing the duodenal barrier defect include acid, bile, the microbiota and food antigens although no causal association with symptoms has been convincingly demonstrated. Recognition of duodenal pathology in FD will hopefully lead to the discovery of new biomarkers and therapeutic targets, allowing biologically targeted rather than symptom-based therapy. In this review, we summarise the recent advances in the diagnosis and treatment of FD with a focus on the duodenum.

Abstract
BACKGROUND Functional dyspepsia (FD) and non-erosive reflux disease (NERD) are gastrointestinal disorders that often overlap. In this randomized, double-blind, placebo-controlled crossover study, the effects of adding acotiamide to treatment with proton pump inhibitors (PPI) were investigated in FD patients with heartburn who failed PPI treatment, corresponding to PPI-resistant NERD. METHODS The subjects included 16 FD patients with heartburn who failed PPI treatment, and they were administered acotiamide or a placebo for 28 days. After suspending medication for 28 days, the trial drug and placebo were crossed over and administered for 28 days. Before the study began and after each administration period, high-resolution impedance manometry (HRiM) was performed, and the modified frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) questionnaire was administered. KEY RESULTS Postprandial fullness in the FD assessment and all modified FSSG items were significantly lower in the acotiamide group than in the placebo group. Esophagogastric junction pressure was significantly higher in the acotiamide group. The distal contractile integral (DCI) pressure and the highest DCI pressure both increased significantly in the acotiamide group. Moreover, in the acotiamide group, the frequency of abnormal primary peristalsis decreased to normal levels; complete bolus transit (CBT), an indicator of esophageal clearance, increased; and CBT time decreased. CONCLUSIONS & INFERENCES Acotiamide was considered to improve upper gastrointestinal functions not only in the stomach but also in the esophagus. Adding acotiamide to PPI therapy appears to improve upper abdominal symptoms in FD patients with heartburn who failed PPI treatment.

Abstract
INTRODUCTION Dietary measures are often advised to patients with gastro-esophageal reflux disease (GERD). Fermentable Oligo-, Di-, Mono-saccharides and Polyols (FODMAPs) induce lower gastrointestinal (GI) symptoms. However, their effects on esophageal motility, including transient lower esophageal sphincter relaxations (TLESRs), reflux events and GERD symptoms are unknown. We investigated the effect of acute administration of two FODMAPs, fructose, and fructans, on the number of TLESRs, reflux episodes and symptom perception in healthy volunteers (HVs). MATERIALS After an overnight fast, 20 HVs (10 males; 32.6 ± 2.8 years) underwent a high-resolution impedance manometry. The number of TLESRs and reflux episodes was quantified during five hours after consumption of a high-caloric meal (740 kcal) enriched with 40 g of either fructose, fructans or glucose (as placebo). Results were analyzed using mixed models. RESULTS There was a trend for a change in the number of TLESRs between the three conditions (P = .06). Post hoc analysis revealed a trend toward a higher number of TLESRs in the fructan condition compared with placebo (Pcorr = .06). Acute administration of fructose did not influence the number of TLESRs. The total number of reflux events was not affected by either FODMAP condition. Lower esophageal sphincter (LES) pressures dropped significantly in the first postprandial hour to recover slowly back to baseline values (P < .0001), without any difference in LES pressure between the three conditions. CONCLUSION Ingestion of fructans increased the number of TLESRs slightly compared with placebo. The effect of FODMAPs such as fructans or a low FODMAP diet on reflux parameters in GERD patients remains to be investigated.

Abstract
Chronic unexplained gastrointestinal symptoms impact more than 1 in 5 Americans and their families; these disorders include the irritable bowel syndrome (IBS) and functional dyspepsia (FD), currently classified by Rome IV as functional gastrointestinal disorders. By definition, IBS and FD have no established pathology, but emerging evidence suggests this paradigm may need revision. Immune activation and, in subsets, subtle intestinal pathology have been identified in FD (most notably, postprandial distress syndrome) and IBS-diarrhea. A disease model is proposed that accounts for all of the intestinal and extraintestinal symptoms, relationship to food and infection, and the overlap with gastroesophageal reflux disease. It is speculated that antigen presentation to the mucosa (e.g., microbial antigens or food proteins after acute gastroenteritis) induces, in a genetically primed host, immune activation of the intestine with low-grade intestinal inflammation and subsequently neuronal structural and functional alterations, producing regional intestinal hypersensitivity and motor dysfunction. Immune activation may explain the female predominance and fluctuations in immune activity for symptom variability over time. In the future, as further evidence accumulates, the management paradigm may potentially shift to objective pathology-based subtyping based on serological, microbiological, and clinical assessments to identify when targeted therapies should be deployed in subsets. Potential targeted interventions may include therapies to dampen down immune activation or block release of key mediators such as histamine, specific microbial targeted treatments that may reverse disease, and dietary advice to eliminate relevant food antigens after objective in vivo testing. Only by identifying causation can we eventually anticipate cure, and as the true pathology unravels in subsets, this may become a reality.

Abstract
BACKGROUND/AIM Gastric dysmotility is one of pathophysiologies of gastroesophageal reflux disease (GERD). The aim of this study was to investigate the effects of transcutaneous electrical acustimulation (TEA) on gastric accommodation and gastric slow waves, and evaluate possible mechanisms in patients with GERD. METHODS Thirty patients were studied in two randomized sessions of sham-TEA and TEA with the measurements of esophageal high-resolution manometry (HRM), gastric accommodation assessed by a nutrient-drinking test, electrogastrogram (EGG), electrocardiogram (ECG), and postprandial dyspeptic symptoms. RESULTS Compared with sham-TEA, TEA improved nutrient drinking-induced fullness (42.0 ± 3.3 vs. 31.0 ± 3.5, P = 0.003) at 10 min after the drink, and belching right after the drink (22.0 ± 4.6 vs. 11.7 ± 3.1, P = 0.012) and at 10 min (16.0 ± 3.8 vs. 3.0 ± 1.5, P = 0.002) after the drink. TEA also improved gastric accommodation (954 ± 37 mL vs. 857 ± 47 mL, P = 0.001) and normalized maximal drink-induced impairment in gastric slow waves. Concurrently, TEA enhanced vagal activity assessed from spectral analysis of heart rate variability in the postprandial state (0.42 ± 0.03 vs. 0.49 ± 0.04, P = 0.039). The vagal activity was positively correlated with the percentage of normal slow waves (r = 0.528; P = 0.003) and negatively correlated with the regurgitation score (r = -0.408, P = 0.025). CONCLUSIONS Acute TEA increases gastric accommodation, improves gastric slow waves, and reduces postprandial fullness and belching, possibly mediated via the vagal mechanisms.

Abstract
BACKGROUND Drugs such as citalopram, "targeting" the serotonin pathway, can alter esophageal mechano-chemical sensitivity and gastrointestinal motility. The aim of this study was to clarify the effect of citalopram on esophageal motility and sphincter function, transient lower esophageal sphincter relaxations (TLESRs), and reflux events. METHODS Sixteen healthy volunteers (HV) receiving 20 mg citalopram or placebo intravenously, in a randomized cross-over fashion, underwent two high-resolution impedance manometry studies involving liquid swallows and a high-fat, high-caloric meal. Manometric, reflux, and symptom-related parameters were studied. KEY RESULTS A lower distal contractile integral was recorded under citalopram, compared with placebo (P = 0.026). Upper esophageal sphincter (UES) resting pressure was significantly higher after citalopram administration throughout the study (P < 0.05, all periods). Similarly, the UES postswallow mean and maximum pressures were higher in the citalopram condition (P < 0.0001, in both cases) and this was also the case for the 0.2 s integrated relaxation pressure (P = 0.04). Esophagogastric junction resting pressures in the citalopram visit were significantly higher during swallow protocol, preprandial period, and the first postprandial hour (P < 0.05, in all cases). TLESRs and total reflux events were both reduced after citalopram infusion (P = 0.01, in both cases). During treatment with citalopram, five participants complained about globus sensation (P = 0.06). This citalopram-induced globus was associated with higher UES postswallow mean and maximum pressure values (P = 0.01 and P = 0.04, respectively). CONCLUSIONS AND INFERENCES Administration of citalopram exerts a diversified response on esophageal motility and sphincter function, linked to clinically relevant phenomena: a reduction in postprandial TLESRs and the induction of drug-induced globus.

Abstract
BACKGROUND It is unexplained why functional dyspepsia and gastro-oesophageal reflux disease (GERD) overlap more often than expected by chance. Post-prandial distress syndrome has been linked to impaired gastric fundic accommodation which may induce increased transient lower oesophageal sphincter relaxations and consequent GERD. Duodenal eosinophilia has been linked to functional dyspepsia and post-prandial distress syndrome. AIM To identify if there is an association between duodenal eosinophilia in functional dyspepsia and symptoms of GERD and whether post-prandial distress syndrome or epigastric pain syndrome are associated with new onset GERD. METHODS Participants (n = 1000) were randomly selected from the national Swedish population register and surveyed by questionnaires and oesophagogastroduodenoscopy in 1999-2001. All eligible subjects (n = 887) were invited to a follow-up study in 2010 (response rate 79%). In a case-control study of 213 subjects (functional dyspepsia vs healthy controls), histology from the duodenum was evaluated at baseline and the possible association of eosinophilia to new onset GERD symptoms was analysed. RESULTS Functional dyspepsia (OR 7.6; 95% CI 2.93-19.4, P < 0.001) and post-prandial distress syndrome at baseline (OR 9.0, 95% CI 3.36-24.0, P < 0.001) were associated with an increased risk of GERD at follow-up. Eosinophilia in the second part of duodenum only was independently associated with an increased risk of GERD amongst those with functional dyspepsia (OR 4.2; 95% CI 1.2-4.77, P = 0.024) and post-prandial distress syndrome at baseline (OR 6.0; 95% CI 1.50-23.6, P = 0.011), respectively. CONCLUSIONS Duodenal eosinophilia is associated with increased risk of GERD at 10-year follow-up in those with functional dyspepsia and post-prandial distress syndrome at baseline. Duodenal eosinophilia may explain the link between GERD and functional dyspepsia, suggesting subsets of functional dyspepsia and GERD may be part of the same disease spectrum.

Neurogastroenterol Motil 2019; 31:e13530. [PMID: 30676686 DOI: 10.1111/nmo.13530] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2018] [Revised: 10/30/2018] [Accepted: 11/27/2018] [Indexed: 01/07/2023]
Abstract
BACKGROUND The aim of this study was to investigate the frequency and circadian changes in transient lower esophageal sphincter relaxations (TLESRs) in normal volunteers using 24-hour high-resolution impedance manometry (HRIM). METHODS Fifteen volunteers underwent HRIM. TLESRs were recorded during the mealtime, 2-hour postprandial, daytime, and supine periods. The catheter was firmly secured to the nose, and subjects went home, ate normal meals, and continued routine daily activities. KEY RESULTS Successful recordings were obtained in 11 volunteers. Overall, 1083 TLESRs were documented; the average occurrence was 4.2/h, and the duration was 21.0 ± 5.2 seconds. The majority of the TLESRs occurred during the 2-hour postprandial (42.7%) and daytime (31.5%) periods, while 10.2% and 15.6% occurred during the mealtime and supine periods, respectively. Eight hundred and eighty-six (81.8%) TLESRs were associated with reflux. Overall, 25.5% of TLESRs were preceded by partial secondary peristalsis (PSP), while 74.5% were preceded by nothing. Terminating events included primary peristalsis (PP; 40.3%), PSP (42.8%), full secondary peristalsis (FSP; 8.2%), or nothing (8.7%). Both preceding and terminating events periodically changed throughout the four periods. One hundred and twelve (10.3%) TLESRs with both preceding and terminating events of PSP, presenting as a "mirror phenomenon," were documented. The majority of these TLESRs occurred during the supine (70.5%). CONCLUSIONS & INFERENCES Transient lower esophageal sphincter relaxations are common physiological motor events in normal volunteers; these events have certain circadian rhythms, as do the events that precede and terminate TLESR events. A special "mirror phenomenon" is observed when both the preceding and terminating events are PSP.

Abstract
Functional dyspepsia (FD) is subdivided into epigastric pain syndrome and postprandial distress syndrome according to the Rome IV consensus. Based on the assumption that disordered gastric motility is a key pathophysiologic factor in postprandial distress syndrome, prokinetic agents are often proposed as the treatment of choice for this subgroup. Although a meta-analysis suggests that prokinetic agents may be efficacious and safe in FD, there is a lack of widely available agents of proven efficacy. This review analyzes some of the difficulties and challenges in establishing therapeutic efficacy of prokinetic drugs in FD.

Abstract
The upper gastrointestinal tract plays an important role in sensing the arrival, amount and chemical composition of a meal. Ingestion of a meal triggers a number of sensory signals in the gastrointestinal tract. These include the response to mechanical stimulation (e.g., gastric distension), from the presence of food in the gut, and the interaction of various dietary nutrients with specific "taste" receptors on specialized enteroendocrine cells in the small intestine culminating in the release of gut hormones. These signals are then transmitted to the brain where they contribute to food intake regulation by modulating appetite as well as feedback control of gastrointestinal functions (e.g., gut motility). There is evidence that the sensitivity to these food related stimuli is abnormally enhanced in functional dyspepsia leading to symptoms such nausea and bloating. In addition, these gut-brain signals can modulate the signaling pathways involved in visceral pain. This review will discuss the role of gut-brain signals in appetite regulation and the role dysregulation of this system play in functional dyspepsia.

Abstract
BACKGROUND Gastric accommodation to a meal may be important in the pathogenesis of upper gastrointestinal disorders, but has been difficult to investigate in a minimally invasive fashion. METHODS We studied gastric and lower esophageal physiology during food intake, combining transabdominal ultrasound, multichannel high-resolution impedance-manometry (HRIM) and a symptom questionnaire. A HRIM catheter was distally positioned at incisura angularis and 300 mL saline with 75 g glucose was ingested. Target variables were recorded for 30 min after fluid intake. KEY RESULTS Fifteen healthy subjects' participated (11W/4M, median age 23.8 y) and all accepted the meal with few symptoms. At incisura angularis maximum change in pressure from pre-intake values was -7.4 mmHg after 60 s (P < .0001), rising to pre-intake values within 20 min. The corresponding area increased significantly from pre-intake values of 8.0 cm2 to 14.1 cm2 shortly after intake (P = .0012), peaked at 5 min and slowly decreased towards 30 min. The corresponding maximum change in stress from pre-intake pressure values was -59.2 mmHg shortly after (P < .0001), reaching pre-intake values within 20 min. Strain rose from 0 shortly before to 0.36 shortly after (P < .0001), peaking at 5 min. At incisura angularis, fullness was positively correlated with area and to strain, while fullness, area, and stress were negatively correlated with pressure. CONCLUSIONS & INFERENCES The multimodal method enabled assessment of the gastric accommodation reflex, stress and strain in the stomach. It triggered few symptoms in healthy volunteers. We propose it to be a more physiological replacement of the barostat technique.

Abstract
Functional dyspepsia (FD) is a common but under-recognized syndrome comprising bothersome recurrent postprandial fullness, early satiety, or epigastric pain/burning. Epidemiologically, there are two clinically distinct FD syndromes (although these often overlap clinically): postprandial distress syndrome (PDS; comprising early satiety or meal-related fullness) and epigastric pain syndrome. Symptoms of gastroesophageal reflux disease overlap with FD more than expected by chance; a subset has pathological acid reflux. The pre-test probability of FD in a patient who presents with classical FD symptoms and no alarm features is high, approximately 0.7. Coexistent heartburn should not lead to the exclusion of FD as a diagnosis. One of the most exciting observations in FD has been the consistent finding of increased duodenal eosinophilia, notably in PDS. Small bowel homing T cells, signaling intestinal inflammation, and increased cytokines have been detected in the circulation, and elevated tumor necrosis factor-α levels have been significantly correlated with increased anxiety. Postinfectious gastroenteritis is a risk factor for FD. Therapeutic options remain limited and provide only symptomatic benefit in most cases. Only one therapy is known to change the natural history of FD–Helicobacter pylori eradication. Treatment of duodenal eosinophilia is under investigation.

Abstract
Functional dyspepsia (FD) is a highly prevalent disorder that affects more than 10% of the population. In the past decade, the theoretical underpinning of the concept of FD has begun to change, in light of new data on the underlying pathophysiological mechanisms of this disorder, with a focus on the duodenum. The Rome IV criteria, published in 2016, note that gastroesophageal reflux disease and irritable bowel syndrome overlap with FD more than expected by chance, suggesting that they may be part of the same disease spectrum. Infection by Helicobacter pylori (H. pylori) may explain a minority of cases of FD and in the Rome IV criteria H. pylori-associated dyspepsia (defined as symptom relief after eradication therapy) is considered a separate entity. Duodenal inflammation characterized by increased eosinophils and in some cases mast cells, may impair the intestinal barrier. Post-infectious gastroenteritis is now an established risk factor for FD. Other risk factors may include atopy, owning herbivore pets and exposure to antibiotics, together with gastroduodenal microbiome disturbances. Small bowel homing T cells and increased cytokines in the circulation occur in FD, correlating with slow gastric emptying, and a possible association with autoimmune rheumatological disease supports background immune system activation. A genetic predisposition is possible. FD has been linked to psychological disorders, but in some cases psychological distress may be driven by gut mechanisms. Therapeutic options are limited and, aside from responders to H. pylori eradication, provide only modest and temporary relief. Advances in understanding FD may alter clinical practice, and the treatment of duodenal inflammation or microbiome alterations may lead to a cure for a subset of these patients in the future.

Abstract
Background/Aims The aim of this study is to investigate the degree of delayed gastric emptying (DGE) and evaluate how the severity of DGE affects gastroesophageal reflux disease (GERD) in neurologically impaired (NI) patients utilizing 24-hour multichannel intraluminal impedance pH measurements (pH/MII) and 13C-acetate breath test (13C-ABT) analyses. Methods 13C-ABT and pH/MII were conducted in 26 NI patients who were referred to our institution due to suspected GERD. At first, correlation analyses were performed to investigate the correlation between the 13C-ABT parameters and the clinical or pH/MII parameters. Thereafter, all patients were divided into 2 groups (DGE and severe DGE [SDGE] group) according to each cut off half emptying time (t1/2, 90-170 minutes). Each pH/MII parameter was compared between the 2 groups in each set-up cutoff t1/2. Results The mean t1/2 of all patients was 215.5 ± 237.2 minutes and the t1/2 of 24 (92.3%) patients were > 100 minutes. Significant moderate positive correlations were observed between both t1/2 and lag phase time and the non-acid reflux related parameters. Furthermore, the patients in the SDGE group demonstrated higher non-acid reflux related parameters than those of the DGE groups when the cutoff was t1/2 ≥ 140 minutes. Conclusion The present study demonstrated that GE with t1/2 ≥ 140 minutes was related to an increase of non-acid exposure reaching up to the proximal esophagus in NI patients, and indicating that NI patients with SDGE might have a high risk of non-acid GERD.

Abstract
The endocannabinoid system (ECS) primarily consists of cannabinoid receptors (CBRs), endogenous ligands, and enzymes for endocannabinoid biosynthesis and inactivation. Although the presence of CBRs, both CB1 and CB2, as well as a third receptor (G-protein receptor 55 [GPR55]), has been established in the gastrointestinal (GI) tract, few studies have focused on the role of cannabinoids on esophageal function. To date, studies have shown their effect on GI motility, inflammation and immunity, intestinal and gastric acid secretion, nociception and emesis pathways, and appetite control. Given the varying and sometimes limited efficacy of current medical therapies for diseases of the esophagus, further understanding and investigation into the interplay of the ECS on esophageal health and disease may present new therapeutic modalities that may help advance current treatment options. In this brief review, the current understanding of the ECS role in various esophageal functions and disorders is presented.

Abstract
BACKGROUND It is unknown why functional gastrointestinal disorders (FGIDs) overlap and limited information exists on risk factors for those with overlap. Our aim was to estimate the prevalence of combinations of FGIDs including reflux (FGIDs-gastroesophageal reflux [GER]), and evaluate potential risk factors for people with multiple disorders in a representative US community. METHODS A population-based study was conducted by mailing a valid GI symptom questionnaire to an age- and gender-stratified random sample of residents of Olmsted County, MN. Rome III definitions were used to identify people with FGIDs, and GER was defined by weekly or more frequent heartburn or acid regurgitation. The prevalence of people meeting multiple symptom complexes was estimated. Moreover, potential risk factors for people with multiple disorders were evaluated. KEY RESULTS A total of 3548 people provided data for each of the necessary symptom questions (mean age: 61±16 years, 54% female). Among these 3548 subjects, 2009 (57%) had no FGIDs-GER, 906 (26%) had a pure FGID-GER, 372 (10%) had 2 FGIDs-GER, and 261 (7%) had 3 or more FGIDs-GER. Somatization as assessed by a higher Somatic Symptom Checklist score (OR=3.3, 95% CI [2.7,4.1]) was associated with an increased odds for those with 3 or more FGIDs-GER compared to subjects with a pure FGID-GER adjusting for age and gender. CONCLUSIONS AND INFERENCES Symptom complex overlap is common rather than rare in the community. GER is an integral symptom complex associated with both upper and lower FGIDs. Somatization is a strong risk factor for multiple FGIDs.

Abstract
We previously reported that cascade stomach was associated with reflux symptoms and esophagitis. Delayed gastric emptying has been believed to initiate transient lower esophageal sphincter relaxation (TLESR). We hypothesized that cascade stomach may be associated with frequent TLESR with delayed gastric emptying. Eleven subjects with cascade stomach and 11 subjects without cascade stomach were enrolled. Postprandial gastroesophageal manometry and gastric emptying using a continuous 13C breath system were measured simultaneously after a liquid test meal. TLESR events were counted in early period (0-60 min), late period (60-120 min), and total monitoring period. Three parameters of gastric emptying were calculated: the half emptying time, lag time, and gastric emptying coefficient. The median frequency of TLESR events in the cascade stomach and non-cascade stomach groups was 6.0 (median), 4.6 (interquartile range) vs 5.0, 3.0 in the early period, 5.0, 3.2 vs 3.0, 1.8 in the late period, and 10.0, 6.2 vs 8.0, 5.0 in the total monitoring period. TLESR events were significantly more frequent in the cascade stomach group during the late and total monitoring periods. In contrast, gastric emptying parameters showed no significant differences between the two groups. We concluded that TLESR events were significantly more frequent in persons with cascade stomach without delayed gastric emptying.

Novel Prokinetic Acotiamide Reduces Transient Lower Esophageal Sphincter Relaxation in Healthy Subjects. Digestion 2017; 92:90-8.

Abstract
BACKGROUND/AIMS Currently, there is no study evaluating the effect of acotiamide on transient lower esophageal sphincter relaxations (TLESRs). The aim of this study was to evaluate the effect of acotiamide on TLESRs using simultaneous high-resolution manometry (HRM) and impedance-pH monitoring. METHODS Ten healthy subjects were enrolled. On day 1, subjects underwent HRM and impedance-pH recordings as a baseline. Subjects ate a 750-kcal liquid meal; recording was continued for 2 h while the subjects were in a sitting position. After the administration of acotiamide 100 mg three times a day for 1 week, subjects underwent HRM and impedance-pH recording under the same protocol. RESULTS A total of 208 TLESRs were identified at baseline. Acotiamide decreased the total number of TLESRs from 208 to 143 (p < 0.05). The rate of reflux events during TLESRs after acotiamide administration was similar to that at baseline (57% after acotiamide vs. 58% at baseline). Bolus clearance time was significantly reduced by acotiamide. CONCLUSIONS Acotiamide was believed to have the potential for reducing TLESRs and for enhancing esophageal bolus clearance in healthy volunteers. Future research is needed to determine whether the effects of acotiamide that reduce TLESRs and enhance esophageal motility could improve symptoms in patients with refractory gastroesophageal reflux disease.

Abstract
BACKGROUND Endogenous opioids (EO) acting on μ-opiod receptors in central and enteric nervous system (ENS) control gastrointestinal motility but it is still unclear whether EO in ENS may control esophageal function in man, thus we will study the effects of methylnaltrexone (MNTX), a peripherally selective, and naloxone (NA), a non-selective μ-opiod receptor antagonist, on esophageal motility in healthy subjects. METHODS Fifteen HV (6 M; 34.1 ± 0.6 years; BMI: 22.1 ± 0.1 kg/m2 ) underwent three esophageal high-resolution manometry impedance (HRiM) studies with 10 saline swallows administered every 30 minutes: drug was administered after 30 minutes (MNTX subcutaneously/NA or saline intravenously), a solid meal after 90 minutes; measurements continued for 120 minutes postprandially. KEY RESULTS Methylnaltrexone did not significantly decrease the upper esophageal sphincter (UES) percentage of relaxation preprandially (72.5 ± 5 vs 66.9 ± 4.6 and 73 ± 3.8%, ANOVA between placebo, MNTX and NA, P=NS) and postprandially (60 minutes: 68.2 ± 5.6 vs 61 ± 5.5 and 67.1 ± 5.6%; 120 minutes: 68 ± 5.9 vs 59.3 ± 5.2 and 67.7 ± 4.7%; ANOVA between placebo, MNTX and NA, P=NS). MNTX and NA did not significantly alter preprandial and postprandial LES resting pressures and integrated relaxation pressure (ANOVA between placebo, MNTX and NA, all P=NS). Peak front velocity and distal contractile integral were not altered pre- and postprandially by MNTX and NA (ANOVA between placebo, MNTX and NA, P=NS). Transient lower esophageal sphincter relaxations (TLESRs') number was not altered by MNTX and NA (ANOVA between placebo, MNTX and NA, all P=NS). CONCLUSIONS AND INFERENCES The peripheral selective and non-selective μ-opioid receptor antagonists MNTX and NA, respectively, do not alter TLESRs occurrence and esophageal peristalsis.

Abstract
Symptoms that can be attributed to the gastroduodenal region represent one of the main subgroups among functional gastrointestinal disorders. A slightly modified classification into the following 4 categories is proposed: (1) functional dyspepsia, characterized by 1 or more of the following: postprandial fullness, early satiation, epigastric pain, and epigastric burning, which are unexplained after a routine clinical evaluation; and includes 2 subcategories: postprandial distress syndrome that is characterized by meal-induced dyspeptic symptoms and epigastric pain syndrome that does not occur exclusively postprandially; the 2 subgroups can overlap; (2) belching disorders, defined as audible escapes of air from the esophagus or the stomach, are classified into 2 subcategories, depending on the origin of the refluxed gas as detected by intraluminal impedance measurement belching: gastric and supragastric belch; (3) nausea and vomiting disorders, which include 3 subcategories: chronic nausea and vomiting syndrome; cyclic vomiting syndrome; and cannabinoid hyperemesis syndrome; and (4) rumination syndrome.

Abstract
One in 10 people suffer from functional dyspepsia (FD), a clinical syndrome comprising chronic bothersome early satiety, or postprandial fullness, or epigastric pain or burning. Postprandial distress syndrome (PDS, comprising early satiety and/or postprandial fullness) and epigastric pain syndrome (EPS) are increasingly accepted as valid clinical entities, based on new insights into the pathophysiology and the results of clinical trials. Diagnosis is based on the clinical history, and exclusion of peptic ulcer and cancer by endoscopy. Evidence is accumulating FD and gastroesophageal ref lux disease are part of the same disease spectrum in a major subset. The causes of FD remain to be established, but accumulating data suggest infections and possibly food may play an important role in subsets. FD does not equate with no pathology; duodenal eosinophilia is now an accepted association, and Helicobacter pylori infection is considered to be causally linked to dyspepsia although only a minority will respond to eradication. In those with EPS, acid suppression therapy is a first line therapy; consider a H2 blocker even if proton pump inhibitor fails. In PDS, a prokinetic is preferred. Second line therapy includes administration of a tricyclic antidepressant in low doses, or mirtazapine, but not a selective serotonin reuptake inhibitor.

Abstract
BACKGROUND Functional dyspepsia (FD) is a common condition, affecting adults in both Western (North America and Europe) and Eastern (Asian) parts of the globe. The prevalence has been reported to range from 5% to 40%, largely due to variation from definition criteria and geographical location. Recent published reports in Western and Eastern populations separately indicate that differences in the epidemiology and clinical patterns of FD may exist. Such differences will have implications for the clinical management of and healthcare strategizing for FD at the local level. PURPOSE This review aims to examine the prevalence and clinical patterns of FD in specific groups, namely Western and Eastern populations, based on the Rome criteria. Further differences in the epidemiological associations of FD will be explored between population-based studies in both the East and the West. Finally, the socio-economic consequences of FD, an important measure of the impact of the disease, will be compared between the East and the West.
