Active clinical trials for "Gastrointestinal Diseases"

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 number of endoscopies performed varies greatly between different countries and does not reflect variations in disease incidents. The costs of unnecessary endoscopies are significant and with a better selection of which patients need to be examined with endoscopy, resources could be saved in healthcare, and a better triage would mean that malignancies and other more serious conditions do not have to wait. An example of unnecessary endoscopy is a colonoscopy in patients with irritable bowel syndrome or gastroscopy in patients with functional dyspepsia. The purpose of the project is, among other things: What diagnostic benefit have gastroscopy, colonoscopy, capsule endoscopy and double balloon enteroscopy for different indications in different age groups? What are the risks of this type of examination? Can patients be better selected based on symptoms, psychometric data or laboratory findings to reduce the number of unnecessary examinations and prioritize those that should be scooped up first? Can changed calling methods reduce the number of late cancellations and rebookings and missed patients?

The objectives of this study are to determine the safety and efficacy of IW-9179 administered to patients with functional dyspepsia (FD).

The primary aim of this pilot study is to assess the feasibility, acceptability, and preliminary evidence of efficacy of a self-guided, cognitive behavioral therapy (CBT)-based mobile app intervention (SparkRx) for symptoms of depression among adolescents being treated in specialty medical care settings at Children's Hospital of Los Angeles (CHLA).

To elucidate the similarities and distinctions in non-pulmonary manifestations of cystic fibrosis (CF) including distal intestinal obstruction syndrome (DIOS) incidence and pancreatic enzyme replacement therapy (PERT) use between US and UK CF populations in a parallel study using data from the UK and US CF registries. To assess how CFTR modulators impacted upon recorded PERT use and incidence of DIOS.

Bleeding from the gastrointestinal tract can originate from the small bowel. Typically, upper and lower endoscopies are unable to identify the site of bleeding and patients need to undergo special endoscopies with longer cameras to examine the small bowel and find the bleeding site. One of the most commonly used scopes to investigate the first part of the small intestinal is called "push enteroscopy". This is an upper endoscopy that uses a pediatric colonoscope, which is longer. To date, it is unknown what percentage of small bowel can be observed with this technique. Hence, this study aimed to determine the extent of small bowel examined by push enteroscopy. Consecutive patients with suspected bleeding from the small intestine will undergo a push enteroscopy and the depth of the examination will be marked with metallic clips. Subsequently, patients will have a capsule endoscopy, which is a little camera that will take multiple pictures of the whole small intestine. The percentage of small bowel that the push enteroscopy examined will be determined by the percentage of small bowel corresponding to the location of the clips visualized on capsule endoscopy.

The purpose of this study is to evaluate whether a medical device/implant (InterStimTM) will help patients to have more normal bowel movements. The InterStimTM device is a neuromodulating device. Neuromodulation is a way of changing the activity of the nervous system by using electrical stimulation. InterStimTM is FDA approved to help people who have a hard time controlling their bowl movements. This is called fecal incontinence.The device is placed near a nerve root in the lower back. It works in a manner similar to a pacemaker by releasing electrical stimulation that triggers the S3 nerve root. When being placed, it is initially tested to make sure it will work using a temporary wire and then, if successful, the device is permanently implanted.

The purpose of this study is to make Domperidone available to patients with gastrointestinal disorders who have failed standard therapy and who might benefit from it.

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.

This is a randomized, multicenter, 2-part, open-label trial of the combination regimen of grazoprevir (GZR [MK-5172]; 100mg), uprifosbuvir (UPR [MK-3682]; 450 mg) and ruzasvir (RZR [MK-8408]; 60 mg) with and without Ribavirin (RBV) in cirrhotic (C) or non-cirrhotic (NC) participants infected with hepatitis C virus (HCV) previously failing a direct-acting antiviral regimen (DAA). The combination regimen, referred to as MK-3682B, will be administered as two fixed-dose combination (FDC) tablets, given once-daily. The study will evaluate the efficacy of MK-3682B with or without RBV as assessed by the proportion of participants achieving Sustained Virologic Response 12 weeks (SVR12) after the end of all study therapy.
