Long Term Outcomes of Bariatric Patients Treated With Surgery or Endoscopy

GERD is common in the obese population. Bariatric procedures are the mainstay of therapy for these patients. Bariatric procedures can be surgical (Roux-en-Y gastric bypass and Vertical sleeve gastrectomy) or endoscopic (endoscopic sleeve gastroplasty). The rate of GERD after either treatment is unknown as is the rate of silent reflux. The study primary objective is to assess the incidence rate of GERD in bariatric patients that undergo either therapy.

A Study to Investigate the Pharmacokinetics and ECG Effects of Linaprazan Glurate

This is a Phase I, single-center, double blind, placebo-controlled, parallel-group, randomized trial designed to evaluate the PK, cardiodynamic ECG effects, safety, and tolerability of single oral doses of linaprazan glurate. The trial will explore the PK properties of linaprazan glurate and linaprazan as well as the cardiodynamic ECG effects, safety, and tolerability after the administration of single doses: 300 mg and 600 mg in Part I of the trial, using formulation A of linaprazan glurate, as well as 150 mg, 275 mg, and up to 2 additional dose levels, using formulation C of linaprazan glurate to reach target linaprazan mean Cmax exposure (5222 nmol/L).

Pre- and Post-Therapy Evaluation of Air-Associated Symptoms in Patients With Gastro-esophageal Reflux Disease (GERD): Assessing the Role of Speech and Language Therapy

Patients with gastroesophageal reflux disease (GERD) may present with concomitant gas-related symptom (GRS) such as supragastric or gastric belching, and aerophagia. Identifying these patients is crucial, as their therapeutic pathway differs substantially from that of patients with "pure" reflux disease. Proceeding directly to antireflux surgery in the presence of untreated air-associated symptoms can lead to catastrophic postoperative outcomes. These partly behavioral disorders can often be effectively managed through targeted speech therapy. Following successful therapy, patients may either experience complete resolution of their symptoms or become suitable candidates for surgical treatment of GERD. As of today, there is very scarce literature on this subject.

Famotidine and Antacids for Treatment of Dyspepsia

The aim of this study is to compare intravenous famotidine, an H2 receptor antagonist, and Maalox/ Mylanta, an oral antacid, in treatment of dyspepsia in the emergency department. The goal of this study is to reduce patients' pain based on the verbal numerical pain scale. The anticipated outcome is for pain levels in both groups to decrease. It is expected that antacids will improve symptoms more quickly and to a greater degree within an hour of taking medication based on the results of similar studies.

Vonaprazan Versus Esomeprazole for Healing of LA Grade B or Higher Esophagitis After POEM

Peroral Endoscopic Myotomy (POEM) is a well-established treatment for achalasia; however, it is frequently associated with gastroesophageal reflux disease (GERD), with many patients developing LA grade B or higher esophagitis. Proton pump inhibitors (PPIs) like Esomeprazole are the standard treatment, but Vonaprazan, a potassium-competitive acid blocker (P-CAB), offers superior acid suppression and may provide enhanced healing in post-POEM reflux esophagitis. Primary Objective: • To compare the healing rates of LA grade B or higher reflux esophagitis at 8 weeks in patients receiving Vonaprazan 20 mg versus Esomeprazole 40 mg. Secondary Objectives * To assess improvement in reflux symptoms using the GERD-Q score at 8 weeks. * To evaluate the incidence of adverse events in each treatment group.

Diaphragmatic Training on GERD

he goal of this clinical trial is to evaluate the effects of diaphragm-oriented breathing training on patients with gastroesophageal reflux disease (GERD). This study will compare two non-invasive respiratory interventions-diaphragmatic breathing exercise (DBE) and volume-oriented incentive spirometry (VIS)-in terms of their impact on esophageal function and health-related quality of life.The main questions it aims to answer are:Does DBE or VIS improve GERD symptoms as measured by the GERD Questionnaire (GERDQ)?Do these interventions reduce esophageal acid exposure time and the number of reflux episodes?Do these interventions improve lower esophageal sphincter (LES) pressure and esophageal motility?Do these interventions improve GERD-related quality of life as measured by the GERD-HRQL questionnaire?Researchers will compare three groups: DBE, VIS, and a control group receiving standard care, to determine whether diaphragm-oriented breathing training provides additional benefits over usual management.Participants will:Be randomly assigned to one of three groups (DBE, VIS, or control)Perform the assigned intervention for 6 weeksUndergo baseline and post-intervention assessments, including symptom questionnaires and esophageal function testing Record symptoms and adherence in a daily diary

Alginate vs Sucralfate for GERD Symptomatic Relief

Gastroesophageal reflux disease (GERD) is a chronic gastrointestinal disorder characterized by the regurgitation of gastric contents into the esophagus.It can also present in an atypical manner such as chest pain, dental erosions, chronic cough, laryngitis, or asthma i.e. extra gastroesophageal symptoms. Sucralfate is a unique anti-ulcer drug and is a basic aluminum salt of sucrose octa-sulfate. It forms a protective layer, enhancing bicarbonate production, demonstrating anti-peptic properties, and fostering tissue growth, regeneration, and repair and it undergoes minimal enteral reabsorption. Alginate is a naturally occurring anionic polymer typically obtained from brown seaweed and has been extensively investigated and used for many biomedical applications, due to its biocompatibility, low toxicity, relatively low cost, and mild gelation by addition of divalent cations such as Ca2+.Both sucralfate and alginate have been in use for the treatment and symptomatic relief of GERD and are well tolerated oral formulations.

PRospective Registry of Esophageal Motility

Digestive physiopathology is a branch of gastroenterology aiming to study patients with upper GI symptoms, mainly gastro-esophageal, potentially indicating the presence of Gastroesophageal Reflux Disease (GERD)/Barrett Esophagus (BE) or obstructive esophageal motility disorders (achalasia being the most relevant), but including also other primary motility disorders such as Esophgago-Gastric Junction Outflow Obstruction (EGJOO), Hypercontractile Esophagus (HE), Distal Esophageal Spasm (DES) and other minor disorders. Physiopathological testing encompasses High-Resolution Manometry (HRM), 24-H esophageal pH-impedance testing, Functional Lumen Imaging Probe (FLIP) assessment. All these tests are designed to provide a clear phenotyping of esophago-gastric disorders related to reflux or obstructive esophageal symptoms, either in naïve patients, as well as after foregut surgery (particularly anti-reflux surgery, achalasia/primary motility disorders treatment).

Heartburn, Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is a condition caused by the reflux of stomach contents into the esophagus, presenting with typical symptoms such as heartburn and acid regurgitation. GERD is a chronic condition that affects quality of life, and patients with this condition are known to have a lower quality of life compared to healthy individuals. In particular, nocturnal heartburn can lead to sleep deprivation and affect daily life, as well as overall quality of life. This study aims to evaluate the efficacy of alleviating nocturnal heartburn symptoms in patients with erosive reflux disease (ERD).
