345 Clinical Trials for Various Conditions
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....
This study aims to identify whether an exclusive human milk diet (EHMD) would improve outcomes in neonates with congenital gastrointestinal disorders (CGD) and by facilitating an earlier transition off of parenteral nutrition (PN).
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.
Background: - Some research studies focus on digestive disorders, such as nutritional, gastrointestinal, and liver disorders. Researchers want to examine and treat people with digestive disorders in order to learn more about these disorders. They also want to study how digestive disorders run in some families. To do so, they will provide standard care to people with digestive disorders. They will also look at relatives of people with digestive disorders, such as parents, children, and siblings. Objectives: * To examine and treat people with digestive disorders. * To evaluate people with digestive disorders for research studies. Eligibility: * Individuals of any age who have digestive disorders. * Individuals at least 2 years of age who are first-degree relatives of the people with digestive disorders. Design: * Participants will have at least one outpatient visit to the National Institutes of Health. The visit will last about 2 hours. * All participants will be screened with a physical exam and medical history. They will also provide different samples for study. Samples may include blood, urine, and stool samples. Saliva and hair samples may also be taken. Skin biopsies and rectal swabs may be collected from adult participants. * Participants with digestive disorders may be able to receive treatment through this study.
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.
Background: - Gastrointestinal diseases and disorders affect the throat, stomach, and intestines. There are many different kinds of these diseases. Clinical trials are being developed to study new ways to treat them. People who are interested in clinical trials need to be screened before they can take part in the studies. Researchers want to evaluate people with different stomach and intestine disorders to see if they are eligible for clinical trials. Objectives: - To study people who have gastrointestinal disorders and see if they are eligible for clinical trials. Eligibility: - Individuals at least 18 years of age who have or may have a gastrointestinal disorder. Design: * Participants will be screened with a physical exam and medical history. Blood, urine, and stool samples will be collected. Imaging studies such as x-rays and ultrasound will check to see if the disorder has affected other organs. * Participants may have tests as needed depending on their disorder. These tests include the following: * Colonoscopy and endoscopy of the large intestine, esophagus, and stomach. * Stomach acid analysis to look at stomach pH levels. * Wireless capsule endoscopy to take pictures of the small intestine. * Hydrogen breath testing to study issues like bloating, diarrhea, and constipation. * Sitz Marker Study to see how fast stool moves through the colon. * Participants may donate extra blood, urine, or stool samples for study. They may also donate stomach contents or tissue from the gut. * Treatment will not be provided as part of this study. However, participants may be admitted to other clinical trials.
The purpose of this study is to prescribe oral domperidone for subjects with gastrointestinal disorders who have failed or suffered adverse effects from standard medical treatment.
The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Autism-spectrum disorder with Gastrointestinal disorders (constipation, diarrhea, and/or abdominal pain). MTT involves a combination of 14 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by 1 day of bowel cleanse using Miralax, followed by 5 days of high dose MTP-101P with an antacid, followed by 12 weeks of a lower maintenance dose of MTP-101P with an antacid.
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.
We will sample intestinal microbiota using a microbiome sampling capsule in Healthy, Irritable Bowel Syndrome (IBS), and Functional Gastrointestinal Disease.
The goal of this observational study has the purpose of collecting biological samples from obese patients undergoing evaluation for weight loss by means of medical or endoscopic therapies; and of post bariatric surgery patients presenting with short- and long-term surgical complications. The aim is to enhance the overall understanding of the mechanisms leading to obesity, weight loss, failure to lose weight, and weight regain following treatment. Additional goals are to determine the efficacy of endoscopic and surgical procedures, to identify potential therapeutic targets and disease biomarkers that predict response to therapy.
TARGET-GASTRO is an observational research study to conduct a comprehensive review of outcomes for patients with the chronic gastrointestinal (GI) diseases: eosinophilic gastrointestinal disease (EGID), ulcerative colitis (UC) or Crohn's disease (CD).
Researchers are trying to learn more about how individuals break down and process specific medications based on their genes. Pharmacogenomics (PGx) is a new, specialized field within individualized medicine. PGx is the study of how genes may affect the body's response to, and interaction with, some prescription medications. Genes carry information that determines things such as eye color and blood type. Genes can also influence how individuals process and respond to medications. Depending on genetic make-up, some medications may work faster or slower or produce fewer side effects.
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
This study will be a retrospective, registry study collecting data of patients who were diagnosed with benign or malignant gastrointestinal diseases. Data will be collected from patient's chart retrospectively once the patients have completed proper treatment follow up with physicians' practice.
The purpose of this retrospective chart-review registry study is to evaluate the safety profile, efficacy profile and cost-effectiveness of the various therapeutic endoscopic ultrasound (EUS) procedures (for benign and malignant gastrointestinal disorders). 1. To assess the clinical and technical success rates of EUS-Guided interventions 2. To document the impact of therapeutic EUS procedures on the management of gastrointestinal disorders including malignancies through cost effective analyses. 3. Compare endoscopic interventions to non-endoscopic interventions for the same clinical indications and evaluate safety and efficacy.
Currently, there is limited multi-center data on endoscopic surgery outcomes in western populations. Evaluation of these measurement would help the investigators compare them to conventional treatment modalities within current tertiary facilities; and consequently help the investigators identify appropriate treatment techniques and improve clinical management of patients at Rutgers RWJMS. The purpose of this retrospective registry study is to assess long term data on efficacy, safety and clinical outcome of Endoscopic Surgery within the gastrointestinal tract.
The purpose of this study is to see if using a micro-current through a device called a TENS (Transcutaneous Electrical Nerve Stimulator) unit helps to improve functional gastrointestinal disorder (FGID) symptoms in children by stimulation of the vagus nerve. The study will compare two methods of stimulation to determine if there is a difference in the two methods.
The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating children with Autism Spectrum Disorder (ASD) and gastrointestinal problems (primarily constipation and/or diarrhea). MTT involves a combination of 10 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by a bowel cleanse, followed by 12 weeks of Fecal Microbiota (FM).
The investigators propose to investigate Microbiota Transfer Therapy (MTT) for treating patients with Pitt Hopkins Syndrome (PTHS) and gastrointestinal problems similar to Irritable Bowel Syndrome (IBS). MTT involves a combination of 10 days of oral vancomycin (an antibiotic to kill pathogenic bacteria), followed by a bowel cleanse, followed by 12 weeks of Fecal Microbiota (FM).
The primary aim of this study is to evaluate the effect and impact of a technology which creates a virtual reality (VR), personalized representation of a patient's endoscopic findings in comparison our standard practice (SP). Our study will compare the level of knowledge, understanding and satisfaction the patient and family have between those receiving SP and those receiving both SP and VR.
This is a clinical trial of Microbiota Transplant Therapy (MTT) for adults with autism spectrum disorders (ASD) who have gastrointestinal problems. Previous research has shown that individuals with ASD have a low diversity of gut bacteria, and low diversity is generally associated with poor gastrointestinal (GI) health. We previously found that MTT therapy for children with ASD and GI symptoms was helpful in reducing their GI symptoms, reducing their ASD symptoms, and increasing their diversity of gut bacteria. This clinical trial will investigate the hypothesis that MTT therapy will be helpful for adults with ASD who have GI symptoms.
Some people develop chronic abdominal pain with diarrhea or constipation after an episode of acute bacterial gastroenteritis. These symptoms can be consistent with post-infectious irritable bowel syndrome (IBS) and can last long after the acute infection is over. The exact reason why certain individuals develop these symptoms whereas others don't is not exactly clear. The researchers are studying changes in gastrointestinal permeability (movement of contents across the lining of the intestine) and transit (movement of food through the gastrointestinal tract). The researchers are also studying if there are any genetic risk factors that are associated with development of this disorder.
The purpose of this study is to investigate a novel thermosensitive topical gel formulation for the treatment of inflammatory bowel disease (IBD), specifically ulcerative colitis.
FDA currently allows patients 12 years of age and older with various gastrointestinal (GI) conditions to be treated with Domperidone through the Expanded Access to Investigational Drugs program. These conditions include gastroesophageal reflux disease with upper GI symptoms, gastroparesis, and chronic constipation. Patients must have failed standard therapies to be eligible to receive Domperidone. This program facilitates availability of investigational drugs, (such as Domperidone) to patients with serious diseases or conditions when there is no comparable or satisfactory alternative therapy to diagnose, monitor, or treat the patient's disease or condition.
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.
The purpose of this study is to determine the patient preference for a biocompatible thermosensitive solution-gel versus water or saline (liquid) enema. The thermosensitive solution-gel is comprised of poloxamer, an inactive compound that is designated as GRAS (generally recognized as safe) by FDA. It could subsequently be used as a medium for drug delivery. The poloxamer (gel) is administered to study participants in order to assess preference and proximal distribution.
This program has been created to help patients with irritable bowel syndrome manage their symptoms and increase their functioning by using cognitive therapy skills and hypnosis.
Background: * Eosinophil-associated gastrointestinal disorders (EGID) are a group of related disorders that affect the esophagus, stomach, and bowel. There are two major types of EGID, eosinophilic esophagitis and eosinophilic gastroenteritis. They are caused by the body's immune system being activated by food allergens, which then damages the gut wall. People with EGID have large numbers of eosinophils (a type of white blood cell) in their gut. EGID can cause difficulty swallowing, abdominal pain, or nausea. * At present, there are no drugs specifically approved to treat EGID. Most adults who have EGID receive steroid therapy to manage the symptoms. However, long-term steroid use may cause other problems in the body. Researchers want to see if low-dose sirolimus can be used to treat EGID. Sirolimus is a drug used to prevent rejection of transplanted organs. It may be able to keep the body's immune cells from being activated by food allergens and decrease the eosinophils. Objectives: - To see if low dose sirolimus is safe and decreases blood or gut eosinophils in EGID. Eligibility: * Individuals between 18 to 65 years of age who have EGID. * Participants must also have an elevated blood eosinophil count and positive blood tests for IgE antibodies to foods. Design: * Participants who are on medicine for EGID or related symptoms must be on a stable dose for 1 month before screening and stay on that dose throughout the study. * Participants will be screened with a medical history and physical exam, and review their symptoms. They will provide blood and urine samples. They will also have heart and lung function tests. Some participants may have allergy skin tests. * At the first study visit, participants will have 2 days of inpatient tests. They will repeat the tests from the screening visit. They will also have a full analysis of the esophagus, stomach, and small intestine. On the second day, they will start to take sirolimus as a liquid with orange juice or water. * Participants will continue to take sirolimus at home. They will record their doses and any symptoms. They will also have a visit to provide blood samples about 2 weeks after the first study visit. * At the second study visit (about a month after the first visit), participants will repeat the tests from the screening visit. The sirolimus dose may be adjusted as needed. * Participants will take sirolimus for at least another 28 days. Depending on the dose of the drug and the blood test results, some participants may need to take it for up to 112 days. Those who take the drug for a longer period will have additional study visits with tests. * There will be another study visit when participants stop taking the drug. The last visit will be a final follow-up visit.
The Eosinophilic Gastrointestinal Disorders (EGIDS) Registry is a longitudinal study that does not involve medical interventions, but serves as a record of demographics, characteristics of disease and treatment, utilization patterns, quality improvement measures and clinical outcomes. The database is proposed so that epidemiologic research can be performed and current and accurate data can be obtained regarding practice patterns, age and gender distributions, efficacy of treatment, clinical outcomes and changes in quality of life.
