Evaluation of Patients With Gastrointestinal Disease

Maryland

Background: Ongoing and future research projects that study gastrointestinal diseases depend on access to biological samples and clinical data. Researchers want to study people who are seen and treated for these diseases. This may help them assess and treat these diseases better in the future. Objective: To collect data and samples from people being seen and/or treated for gastrointestinal problems at NIH, to use in future research. Eligibility: Adults aged 18 and older who have known or suspected gastrointestinal disorders or need screening, treatment, or follow-up per current medical guidelines. Design: Participants will be screened with a physical exam. Their medical records will be reviewed. Participants will be seen by doctors based on the ailment they have. Their condition will be treated just like it would at a doctor s office. But the data and samples collected will be used for future research. Participants may give blood, urine, and/or stool samples. If participants have an endoscopy or colonoscopy as part of their standard care and samples are taken, they may be asked to give their leftover samples to NIH. Or, they may be asked to have extra samples taken for NIH to use. These samples may include gastric acid and/or tissue from the lining of the stomach or intestines. If samples are not taken as part of their standard care, they may be asked to have samples taken for NIH to use. Data will be stored at NIH. The data systems are password protected. Samples will be coded. Participants will take part in the study for as long as they agree to be seen for their disease....

Mayo Clinic Upper Digestive Disease Survey

Minnesota · Rochester, MN

The Mayo Clinic Conduit Report Card Questionnaires have been created in order to have a consistent evaluation tools for patients undergoing esophageal reconstruction or treatment or patients that are experiencing an upper digestive disease in order to standardize and validate outcome measures. Data will be used to establish the validation of the questionnaires/survey. Data will also lead to the establishment of "normal" or expected scores for patients undergoing each type of esophagectomy procedure and for upper digestive diseases. Data will contribute to creating treatment algorithms for symptom management for upper digestive diseases and for post-operative complications and symptoms as well as contribute to pre-operative education.

Domperidone in Treating Patients With Gastrointestinal Disorders

Texas · Houston, TX

This phase III trial studies how well domperidone works in treating patients with gastrointestinal disorders. Domperidone may help control chronic gastrointestinal disorders and their symptoms, such as pain, bloating, and nausea and vomiting, by stimulating contraction of the stomach to increase its ability to empty itself of food.

Microbiota Transfer Therapy for Children and Adults With Both Pitt Hopkins Syndrome and Gastrointestinal Disorders

Arizona · Tempe, AZ

The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Pitt-Hopkins Syndrome (PTHS) and gastrointestinal problems (constipation, bloating, abdominal pain). MTT involves a combination of 10 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by 1 day of bowel cleanse using magnesium citrate, followed by 4 days of high dose MTP-101P with an antacid, followed by 12 weeks of a lower maintenance dose of MTP-101P with an antacid.

Capsule Microbiota Sampling in IBS/Functional Gastrointestinal Disease

California · Redwood City, CA

We will sample intestinal microbiota using a microbiome sampling capsule in Healthy, Irritable Bowel Syndrome (IBS), and Functional Gastrointestinal Disease.

Eosinophilic Gastrointestinal Disorders Registry

Illinois · Chicago, IL

The purpose of this study is to learn more about Eosinophilic Gastrointestinal Disorders (EGIDs). With this registry we hope to find out more about the symptoms that patients have during their treatment, the quality of life they have with the diagnosis, what the disease looks like throughout the different treatment methods, and if there is a connection between EGIDs and connective tissue disorders. The goal of this study is to be able to better understand EGIDs and use information gained from all the information collected on this study for more precise treatments in the future. We want to create a large collection of samples, called a biorepository, to learn the most about EGIDs as possible. When the samples are collected, which will occur at procedures directed by your child's doctor as part of their standard of care, they will be stored for an unlimited amount of time to perform experiments on these samples and to gather information about EGIDs

OMEGA: Outcome Measures in Eosinophilic Gastrointestinal Disorders Across the Ages

Arizona · Phoenix, AZ

The purpose of this observational study is to find the best measures to define how well a person with eosinophilic disorder is doing. People with EoE, EoG, EoN and EoC normally undergo endoscopy and/or colonoscopy where cells are collected for microscopic analysis. Treatments are then decided based on how the cells look. We are aiming to compare different tissue components such as inflammatory cell types with clinical symptoms. We want to see if scores on standard questionnaires can give us an idea how well the person is doing.

Telehealth-Delivered Gut-Directed Hypnotherapy for Managing GI Health

Florida · Orlando, FL

This study aims to evaluate the specific and non-specific effects of hypnotherapy and to evaluate the efficacy of group-format gut-directed hypnotherapy (GDH) delivered via telehealth for managing gastrointestinal health.

Autonomic Reactivity and Personalized Neurostimulation

Wisconsin · Milwaukee, WI

Disorders of gut-brain interaction (DGBI) affect up to 25% of U.S. children. Patients often suffer from disabling, multisystem comorbidities that suggest a common root (sleep disturbances, fatigue, anxiety, etc). Yet, DGBI are defined and treated based on GI symptom origin (cyclic vomiting, dyspepsia, irritable bowel) rather than underlying pathophysiology. Many patients manifest comorbidities suggesting an underlying autonomic nervous system (ANS) dysregulation (palpitations, dizziness, cognitive dysfunction). Unfortunately, due to common features of anxiety and visceral hyperreactivity and lack of obvious pathology, children with DGBI are frequently diagnosed with psychosomatic or 'benign, functional disorders' and treated with empiric antidepressants despite lack of scientific support and risks of serious side effects. Little is known about the underlying brain-gut mechanisms linking these comorbidities. A lack of targeted treatment options naturally follows the paucity of mechanistic data. A dysregulated ANS response circuit via brainstem nuclei is linked to visceral hypersensitivity. As the team's prior research has shown, ANS regulation can be non-invasively measured via several validated indices of cardiac vagal tone. Using the novel vagal efficiency (VE) metric, the investigators have demonstrated inefficient vagal regulation in cyclic vomiting syndrome and pain-related DGBI and that low VE predicts response to non-invasive, auricular percutaneous electrical nerve field stimulation (PENFS) therapy. PENFS targets brainstem vagal afferent pathways and, along with brain-gut interventions such as hypnotherapy, are the only therapies currently proven effective for pediatric DGBI. Individualizing neurostimulation based on sensory thresholds while assessing dynamic ANS reactivity offers a path towards personalized medicine using the most effective therapies to date. This proposal will test the feasibility of an ANS tracking software in assessing real-time, autonomic regulation and providing individualized neurostimulation in children with nausea/vomiting and ANS imbalance.

Ritual Synbiotic+, a Dietary Supplement Designed to Impact Gastrointestinal Health, Mood, and Behavior in Women

Colorado · Fort Collins, CO

The aim of this study is to determine how regular consumption of Synbiotic+, a dietary supplement that contains prebiotics, probiotics, and postbiotics, impacts functional gastrointestinal health, markers of intestinal inflammation and immune health, and influences mood and behavior. The primary outcome will be to assess gastrointestinal health using bowel movement tracking, self-report and objective assessments of gastrointestinal symptom severity, stool levels of short chain fatty acids, changes in the gut microbiota, including recovery of LGG and BB-12, and functional measures of the microbiome. Secondary outcomes will include stool and blood markers of gut barrier function and intestinal inflammation, immune health, and self-assessments of stress, anxiety, sleep, and quality of life.
