Abstract
Gastroesophageal reflux disease (GERD) in the elderly is characterized by atypical symptoms, relatively severe esophageal injury, and more complications, and when GERD is treated, it is also necessary to fully consider the general health condition of the elderly patients. This consensus summarized the epidemiology, pathogenesis, clinical manifestations, and diagnosis and treatment characteristics of GERD in the elderly, and provided relevant recommendations, providing guidance for medical personnel to correctly understand and standardize the diagnosis and treatment of GERD in the elderly.

Abstract
Gastroesophageal reflux disease (GERD) is primarily a motor disorder, and its pathogenesis is multifactorial. As a consequence, treatment should be able to address the underlying pathophysiology. Proton pump inhibitors (PPIs) are the mainstay of medical therapy for GERD, but these drugs only provide the control of symptoms and lesions without curing the disease. However, continuous acid suppression with PPIs is recommended for patients with Barrett's esophagus because of their potential chemopreventive effects. In addition to the antisecretory activity, these compounds display several pharmacological properties, often overlooked in clinical practice. PPIs can indeed affect gastric motility, exert a mucosal protective effect, and an antioxidant, anti-inflammatory, and antineoplastic activity, also protecting cancer cells from developing chemo- or radiotherapeutic resistance. Even in the third millennium, current pharmacologic approaches to address GERD are limited. Reflux inhibitors represent a promise unfulfilled, effective and safe prokinetics are lacking, and antidepressants, despite being effective in selected patients, give rise to adverse events in a large proportion of them. While waiting for new drug classes (like potassium-competitive acid blockers), reassessing old drugs (namely alginate-containing formulations), and paving the new avenue of esophageal mucosal protection are, at the present time, the only reliable alternatives to acid suppression.

Glutamatergic Signaling Along The Microbiota-Gut-Brain Axis. Int J Mol Sci 2019; 20:ijms20061482.

Abstract
A complex bidirectional communication system exists between the gastrointestinal tract and the brain. Initially termed the “gut-brain axis” it is now renamed the “microbiota-gut-brain axis” considering the pivotal role of gut microbiota in maintaining local and systemic homeostasis. Different cellular and molecular pathways act along this axis and strong attention is paid to neuroactive molecules (neurotransmitters, i.e., noradrenaline, dopamine, serotonin, gamma aminobutyric acid and glutamate and metabolites, i.e., tryptophan metabolites), sustaining a possible interkingdom communication system between eukaryota and prokaryota. This review provides a description of the most up-to-date evidence on glutamate as a neurotransmitter/neuromodulator in this bidirectional communication axis. Modulation of glutamatergic receptor activity along the microbiota-gut-brain axis may influence gut (i.e., taste, visceral sensitivity and motility) and brain functions (stress response, mood and behavior) and alterations of glutamatergic transmission may participate to the pathogenesis of local and brain disorders. In this latter context, we will focus on two major gut disorders, such as irritable bowel syndrome and inflammatory bowel disease, both characterized by psychiatric co-morbidity. Research in this area opens the possibility to target glutamatergic neurotransmission, either pharmacologically or by the use of probiotics producing neuroactive molecules, as a therapeutic approach for the treatment of gastrointestinal and related psychiatric disorders.

Melatonin in Prevention of the Sequence from Reflux Esophagitis to Barrett's Esophagus and Esophageal Adenocarcinoma: Experimental and Clinical Perspectives. Int J Mol Sci 2018; 19:E2033.

Abstract
Melatonin is a tryptophan-derived molecule with pleiotropic activities which is produced in all living organisms. This "sleep" hormone is a free radical scavenger, which activates several anti-oxidative enzymes and mechanisms. Melatonin, a highly lipophilic hormone, can reach body target cells rapidly, acting as the circadian signal to alter numerous physiological functions in the body. This indoleamine can protect the organs against a variety of damaging agents via multiple signaling. This review focused on the role played by melatonin in the mechanism of esophagoprotection, starting with its short-term protection against acute reflux esophagitis and then investigating the long-term prevention of chronic inflammation that leads to gastroesophageal reflux disease (GERD) and Barrett's esophagus. Since both of these condition are also identified as major risk factors for esophageal carcinoma, we provide some experimental and clinical evidence that supplementation therapy with melatonin could be useful in esophageal injury by protecting various animal models and patients with GERD from erosions, Barrett's esophagus and neoplasia. The physiological aspects of the synthesis and release of this indoleamine in the gut, including its release into portal circulation and liver uptake is examined. The beneficial influence of melatonin in preventing esophageal injury from acid-pepsin and acid-pepsin-bile exposure in animals as well as the usefulness of melatonin and its precursor, L-tryptophan in prophylactic and supplementary therapy against esophageal disorders in humans, are also discussed.

Abstract
BACKGROUND A subset of patients with large paraesophageal hernias have more than 75% of the stomach herniated above the diaphragm; such cases are referred to as intrathoracic stomach (ITS). Herein, we report longitudinal symptomatic outcomes over a decade after surgical ITS repair in a large patient cohort. METHODS Patients who underwent surgical treatment for ITS from 01/2004 to 05/2016 were studied. Preoperative and follow-up data were prospectively collected. Patients completed a standardized symptom questionnaire 1 year postoperatively and at 2-year intervals thereafter. RESULTS In total, 235 patients were reviewed. The mean age was 70.0 ± 11.6 years; 174 patients (74.0%) were women. Surgical procedures included 7 transthoracic repairs and 228 transabdominal repairs (222 laparoscopic, 2 open, 4 laparoscopic-to-open conversions). Anti-reflux procedures were performed in 173 patients (73.6%). 33 patients (14.0%) had mesh reinforcement of hiatal closure; 11 (4.7%) underwent Collis gastroplasty. Follow-up symptom questionnaires at 1, 3, 5, 7, 9, and 11 years were available for 81, 48, 47, 30, 33, and 38% of patients, respectively. Significant and lasting symptom improvement was reported at all follow-up time points. Mean satisfaction scores of 9.3, 9.1, 9.3, 9.0, 9.5, and 9.8 on a 1-10 scale were recorded at the aforementioned intervals. CONCLUSIONS Long-term clinical outcomes confirm that laparoscopic ITS repair is safe and durable, and is associated with a high degree of patient satisfaction and symptom resolution.

Abstract
INTRODUCTION Medical therapy of gastroesophageal reflux disease (GERD) is based on the use of proton pump inhibitors (PPIs) as first choice treatment. Despite their effectiveness, about 20-30% of patients report an inadequate response and alternative drugs are required. Areas covered: This review provides an overview of current pharmacotherapy for treating GERD by showing the results of PPIs, reflux inhibitors, antidepressants and mucosa protective medications. Expert opinion: Medical therapy of GERD does not definitely cure the disease, because even PPIs are not able to change the key factors responsible for it. However, they remain the mainstay of medical treatment, allowing us to alleviate symptoms, heal esophagitis and prevent complications in the majority of cases. Nevertheless, many patients do not respond, because acid does not play any pathogenetic role. Prokinetics and reflux inhibitors have the potential to control motor abnormalities, but the results of clinical trials are inconsistent. Antidepressant drugs are effective in specific subgroups of NERD patients with visceral hypersensitivity, but larger, controlled clinical studies are necessary. Protective drugs or medical devices have been recently adopted to reinforce mucosal resistance and preliminary trials have confirmed their efficacy either combined with or as add-on medication to PPIs in refractory patients.

Abstract
Gastroesophageal reflux disease (GERD) is a common condition that has a substantial impact on quality of life in patients and is a leading risk factor for esophageal adenocarcinoma. Now therapy with proton pump inhibitors (PPIs) is a basic method in the treatment of patients with GERD; however, one third of the patients do not respond to the therapy used. The causes of refractory GERD are a fairly large group of heterogeneous factors contributing to the inefficacy of PPIs in adequate dosage. Among these factors, there is low compliance by patients to the prescribed treatment regimen; nocturnal acid breakthrough; СУР2С19 gene polymorphism; chiasm syndrome with functional diseases of the gastrointestinal tract; non-acidic refluxes in a patient; thoracic esophageal motility disorders; the increased number and duration of transient lower esophageal sphincter relaxation periods; hiatus hernia; and misdiagnosis. 24-hour pH impedance and high-resolution esophageal manometry are now the most informative diagnostic techniques in patients who fail to respond to PPI therapy. These techniques allow one to timely recognize the causes of refractory GERD, to make a differential diagnosis with other nosological entities, and to timely correct therapy for each individual patient.

Abstract
INTRODUCTION The evaluation of symptom association between gastroesophageal reflux and cardiorespiratory events in preterm infants remains unclear. This paper describes a conservative approach to decision-making of anti-reflux surgery through symptom association analysis. METHODS Forty-three neonates with potentially reflux-related cardiorespiratory symptoms underwent synchronized esophageal impedance-pH and cardiorespiratory monitoring. Three indices were considered to evaluate symptom association, the symptom index (SI), the symptom sensitivity index (SSI) and the symptom association probability (SAP). A conservative strategy was adopted regarding the decision of anti-reflux surgery, and therefore, patients were scheduled for laparoscopic Nissen fundoplication if the three indices showed a positive assessment of symptom association. Retrospectively, these indices and the binomial symptom index (BSI) were contrasted against the decision of anti-reflux surgery using different windows of association. RESULTS Thirteen patients showed positive symptom association but only two underwent anti-reflux surgery. The SI and the SSI showed an increasing trend with the width of the window of association. The SAP was affected randomly by slightly altering the windowing parameters. The BSI showed the best performance with the two-minute window (κ =0.78) CONCLUSIONS: The pathology under study is known to improve with maturity. However, the severity of cardiorespiratory symptoms may threaten the neonate's life and therefore, in some occasions, invasive treatments must be considered to protect life. The BSI provides a good prediction of a combination of positive SI, SSI and SAP, which may improve clinical decisions. However, further clinical studies are required to prove the BSI as an optimal predictor of clinical outcomes.

Abstract
Several studies have been carried out in the last 30 years in the attempt to clarify the possible role of glutamate as a neurotransmitter/neuromodulator in the gastrointestinal tract. Such effort has provided immunohistochemical, biomolecular and functional data suggesting that the entire glutamatergic neurotransmitter machinery is present in the complex circuitries of the enteric nervous system (ENS), which participates to the local coordination of gastrointestinal functions. Glutamate is also involved in the regulation of the brain-gut axis, a bi-directional connection pathway between the central nervous system (CNS) and the gut. The neurotransmitter contributes to convey information, via afferent fibers, from the gut to the brain, and to send appropriate signals, via efferent fibers, from the brain to control gut secretion and motility. In analogy with the CNS, an increasing number of studies suggest that dysregulation of the enteric glutamatergic neurotransmitter machinery may lead to gastrointestinal dysfunctions. On the whole, this research field has opened the possibility to find new potential targets for development of drugs for the treatment of gastrointestinal diseases. The present review analyzes the more recent literature on enteric glutamatergic neurotransmission both in physiological and pathological conditions, such as gastroesophageal reflux, gastric acid hypersecretory diseases, inflammatory bowel disease, irritable bowel syndrome and intestinal ischemia/reperfusion injury.

Abstract
Transient lower esophageal sphincter relaxation (TLESR) is the major mechanism of gastroesophageal reflux, but the regulation of TLESR by stimuli in the esophagus is incompletely understood. We have recently reported that acid infusion in the esophagus substantially (by 75%) increased the number of meal-induced TLESR in healthy subjects. We concluded that the TLESR reflex triggered by gastric distention with meal was enhanced by the stimulation of esophageal nerves by acid. However, the possibilities that the acid infused into the esophagus acts after passing though lower esophageal sphincter in stomach to enhance TLESR, or that the acid directly initiates TLESR from the esophagus were not addressed. Here, we evaluated the effect of acid infusion into the proximal stomach on meal-induced TLESR (study 1) and the ability of acid infusion into the esophagus to initiate TLESR without prior meal (study 2). We analyzed TLESRs by using high-resolution manometry in healthy subjects in paired randomized studies. In study 1, we found that acid infusion into the proximal stomach did not affect TLESRs induced by standard meal. The number of meal-induced TLESRs following the acid infusion into the proximal stomach was similar to the number of meal-induced TLESRs following the control infusion. In study 2, we found that acid infusion into the esophagus without prior meal did not initiate TLESRs. We conclude that the increase in the meal-induced TLESRs by acid in the esophagus demonstrated in our previous study is not attributable to the action of acid in the stomach or to direct initiation of TLESR from the esophagus by acid. Our studies are consistent with the concept that the stimuli in the esophagus can influence TLESRs. The enhancement of TLESR by acid in the esophagus may contribute to pathogenesis of gastroesophageal reflux in some patients.

Abstract
Gastro-oesophageal reflux has long been suspected of implication in the genesis and progression of idiopathic pulmonary fibrosis (IPF). We hypothesised that hiatal hernia may be more frequent in IPF than in other interstitial lung disease (ILD), and that hiatal hernia may be associated with more severe clinical characteristics in IPF.We retrospectively compared the prevalence of hiatal hernia on computed tomographic (CT) scans in 79 patients with IPF and 103 patients with other ILD (17 scleroderma, 54 other connective tissue diseases and 32 chronic hypersensitivity pneumonitis). In the IPF group, we compared the clinical, biological, functional, CT scan characteristics and mortality of patients with hiatal hernia (n=42) and without hiatal hernia (n=37).The prevalence of hiatal hernia on CT scan at IPF diagnosis was 53%, similar to ILD associated with scleroderma, but significantly higher than in the two other ILD groups. The size of the hiatal hernia was not linked to either fibrosis CT scan scores, or reduction in lung function in any group. Mortality from respiratory causes was significantly higher among IPF patients with hiatal hernia than among those without hiatal hernia (p=0.009).Hiatal hernia might have a specific role in IPF genesis, possibly due to pathological gastro-oesophageal reflux.

Abstract
BACKGROUND Transient lower esophageal sphincter relaxation (TLESR) is the major mechanism of gastroesophageal reflux (GER) but the regulation of TLESR by stimuli in the esophagus is incompletely understood. If stimuli in the esophagus can influence TLESR, then such regulation may perpetuate or limit GER. We addressed the hypothesis that acid in the esophagus enhances TLESRs. METHODS We evaluated the effect of acid infusion into the distal esophagus on TLESRs evoked by a standard meal in a paired randomized study in healthy subjects. TLESRs were evaluated by using high resolution manometry (HRM). KEY RESULTS We found that acid in the esophagus enhanced meal-induced TLESRs. Compared to control infusion the number of TLESRs (median [interquartile range]) was increased during 2 h following the acid infusion (11 [9-14] vs 17 [12.5-20], p < 0.01). The average duration of individual TLESRs was not affected. The time-course analysis revealed that a robust increase in TLESRs occurred already in the first hour when the number of TLESRs nearly doubled (6 [5.5-7.5] vs 11 [7.5-12.5], p < 0.05). In contrast to the enhancement of TLESRs, the number of swallows was not changed. CONCLUSIONS & INFERENCES The acid infusion into the esophagus increases the number of meal-induced TLESRs in healthy subjects. Our results provide evidence for the concept that the stimuli in the esophagus can influence TLESRs. The regulation of TLESR by stimuli in the esophagus may contribute to pathogenesis of GER in some patients.

United European Gastroenterol J 2014; 1:346-50.

Abstract
BACKGROUND There is a general belief that gastro-oesophageal reflux increases after meals and especially following a rapid intake. OBJECTIVE To evaluate the impact of rapid vs. slow food intake on gastro-oesophageal reflux disease (GORD) patients. MATERIALS AND METHODS Forty-six GORD patients with heartburn and / or acid regurgitation once a week or more often common were included in this study. Participants were asked to eat the same standard meal within either 5 or 30 minutes under observation in a random order on 2 consecutive days. A total of 28 hours of recording were obtained by intraoesophageal impedance pH and number of liquid and mixed reflux episodes within 3 hours of the slow- and fast-eating postprandial periods were calculated. RESULTS While all patients defined GORD symptoms, 10 (21.7%) had pathological 24-h intraoesophageal impedance measurement, 15 (32.6%) had pathological DeMeester and 21.7% had erosive oesophagitis. No difference has been shown according to the eating speed when all reflux episodes were taken together (754 vs. 733). Speed of food intake also did not have an impact on patients with normal vs. pathological 24-h intraoesophageal impedance or erosive vs. non-erosive. During the first postprandial hour, approximately half of the reflux events were non-acid, compared to 34.2% during the second hour and 26.8% during the third hour (p < 0.001). The number of acid reflux episodes was significantly higher than non-acid reflux especially during the second and third hours and in total for 3 hours. CONCLUSIONS This first study addressing the effect of eating speed on reflux episodes in GORD patients did not support the general belief that reflux increases following fast eating. Acid and non-acid reflux were similar at the first postprandial hour, then acid reflux episodes were predominantly higher, which implicate the importance of acid pockets.

An alginate-antacid formulation localizes to the acid pocket to reduce acid reflux in patients with gastroesophageal reflux disease. Clin Gastroenterol Hepatol 2013; 11:1585-91; quiz e90. [PMID: 23669304 DOI: 10.1016/j.cgh.2013.04.046] [Citation(s) in RCA: 81] [Impact Index Per Article: 7.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/23/2013] [Revised: 04/24/2013] [Accepted: 04/25/2013] [Indexed: 02/07/2023]
Abstract
BACKGROUND & AIMS Alginate rafts (polysaccharide polymers that precipitate into a low-density viscous gel when they contact gastric acid) have been reported to form at the acid pocket, an unbuffered pool of acid that floats on top of ingested food and causes postprandial acid reflux. We studied the location of an alginate formulation in relation to the acid pocket and the corresponding effects on reflux parameters and acid pocket positioning in patients with gastroesophageal reflux disease (GERD). METHODS We randomly assigned patients with symptomatic GERD and large hiatal hernias to groups who were given either (111)In-labeled alginate-antacid (n = 8, Gaviscon Double Action Liquid) or antacid (n = 8, Antagel) after a standard meal. The relative positions of labeled alginate and acid pocket were analyzed for 2 hours by using scintigraphy; reflux episodes were detected by using high-resolution manometry and pH-impedance monitoring. RESULTS The alginate-antacid label localized to the acid pocket. The number of acid reflux episodes was significantly reduced in patients receiving alginate-antacid (3.5; range, 0-6.5; P = .03) compared with those receiving antacid (15; range, 5-20), whereas time to acid reflux was significantly increased in patients receiving alginate-antacid (63 minutes; range, 23-92) vs those receiving antacid (14 minutes; range, 9-23; P = .01). The acid pocket was located below the diaphragm in 71% of patients given alginate-antacid vs 21% of those given antacid (P = .08). There was an inverse correlation between a subdiaphragm position of the acid pocket and acid reflux (r = -0.76, P < .001). CONCLUSIONS In a study of 16 patients with GERD, we observed that the alginate-antacid raft localizes to the postprandial acid pocket and displaces it below the diaphragm to reduce postprandial acid reflux. These findings indicate the importance of the acid pocket in GERD pathogenesis and establish alginate-antacid as an appropriate therapy for postprandial acid reflux.

Abstract
Gastroesophageal reflux disease is a common clinical entity in Western societies. Its association with hiatal hernia has been well documented; however, the comparative clinical profile of patients in the presence or absence of hiatal hernia remains mostly unknown. The aim of the present study was to delineate and compare symptom, impedance, and manometric patterns of patients with and without hiatal hernia. A cumulative number of 120 patients with reflux disease were enrolled in the study. Quality of life score, demographic, symptom, manometric, and impedance data were prospectively collected. Data comparison was undertaken between patients with and without hiatal hernia. A P-value < 0.05 was considered statistically significant. Patients with hiatal hernia tended to be older than patients without hernia (52.3 vs. 48.6 years, P < 0.05), whereas quality of life scores were slightly better for the former (97.0 vs. 88.2, P= 0.005). Regurgitation occurred more frequently in patients without hiatal hernia (78.3% vs. 93.9%, P < 0.05). Otherwise, no differences were found with regard to esophageal and extraesophageal symptoms. However, lower esophageal sphincter pressures (7.7 vs. 10.0 mmHg, P= 0.007) and more frequent reflux episodes (upright, 170 vs. 134, P= 0.01; supine, 41 vs. 24, P < 0.03) were documented for patients with hiatal hernia on manometric and impedance studies. Distinct functional characteristics in patients with and without hiatal hernia may suggest a tailored therapeutic management for these diverse patient groups.

Abstract
Gastroesophageal reflux disease (GERD), a common disorder with troublesome symptoms caused by reflux of gastric contents into the esophagus, has adverse impact on quality of life. A variety of medications have been used in GERD treatment, and acid suppression therapy is the mainstay of treatment for GERD. Although proton pump inhibitor is the most potent acid suppressant and provides good efficacy in esophagitis healing and symptom relief, about one-third of patients with GERD still have persistent symptoms with poor response to standard dose PPI. Antacids, alginate, histamine type-2 receptor antagonists, and prokinetic agents are usually used as add-on therapy to PPI in clinical practice. Development of novel therapeutic agents has focused on the underlying mechanisms of GERD, such as transient lower esophageal sphincter relaxation, motility disorder, mucosal protection, and esophageal hypersensitivity. Newer formulations of PPI with faster and longer duration of action and potassium-competitive acid blocker, a newer acid suppressant, have also been investigated in clinical trials. In this review, we summarize the current and developing therapeutic agents for GERD treatment.

Abstract
BACKGROUND Posture has been shown to influence the number of transient lower esophageal sphincter relaxation (TLESRs) and gastroesophageal reflux (GER), however, the physiology explaining the influence of right lateral position (RLP), and left lateral position (LLP) is not clear. The aim of this study was to determine the influence of RLP and LLP on TLESRs and GERD after a meal in GER disease (GERD) patients and healthy controls (HC) while monitoring gastric distension and emptying. METHODS Ten GERD patients and 10 HC were studied for 90 min (30 min test meal infusion, 30 min postprandial in either RLP or LLP (randomly assigned) and 30 min in alternate position). The study was repeated on a separate day in reverse position order. TLESRs, GER, and gastric emptying rate were recorded using manometry, multichannel intraluminal impedance, and (13) C-octanoate breath tests. Gastric distension was visualized by five serial gastric volume scintigraphy scans during the first 30 min. KEY RESULTS Gastroesophageal reflux, (GER) disease patients had increased numbers of TLESRs in RLP compared to LLP in the first postprandial hour [5 (4-14) and 4.5 (2-6), respectively, P = 0.046] whereas the number of TLESRs was not different in RLP and LLP [4 (2-4) and 4 (3-6), respectively, P = 0.7] in HC. Numbers of GER increased similar to TLESRs in GERD patients. In GERD patients, gastric emptying reached peak (13)CO(2) excretion faster and proximal gastric distension was more pronounced. CONCLUSIONS & INFERENCES In GERD patients, TLESRs, GER, distension of proximal stomach, and gastric emptying are increased in RLP compared to LLP. This effect is not seen in HC.

Abstract
Acid suppression, with proton pump inhibitors (PPI), is the mainstay of therapy for reflux disease; despite this, symptoms and injury persist in many patients. Novel approaches have focused on (1) augmenting acid suppression with reformulated current PPIs, new PPIs or new acid pump blockers and (2) preventing reflux with reflux inhibitors. Other strategies to reduce reflux, improve gastric emptying or esophageal clearance, protect the mucosa, or reduce esophageal sensitivity are under investigation alone or in combination with PPIs; however, novel approaches face significant challenges. The safety and efficacy of current PPIs hamper demonstration of clinical superiority for new acid suppressants, and the multifactorial etiology of reflux disease means that monotherapy using a non-acid suppressant is unlikely to match PPI therapy while combination therapy will be superior only if susceptible patients can be identified reliably. Advances will come, not from a 'one size fits all' approach but rather from novel pharmaceuticals allied to novel investigations to permit targeted, personalized reflux therapy.

Abstract
Symptomatic gastro-esophageal reflux disease (GERD) is a very common disease. The consequence of GERD is not only erosive esophagitis, but also esophageal stricture, Barrett’s esophagus and extra-esophageal damage (including the lungs, throat, sinuses, middle ear and teeth). GERD and Barrett’s esophagus are also identified as major risk factors for esophageal carcinoma. Therapy with melatonin prevents esophageal injury from acid-pepsin and acid-pepsin-bile exposure in animals, then further studies are required in humans to establish whether a melatonin supplement is able to protect the patients with GERD from erosions, Barrett’s and neoplasia.
