This study looks at the viruses (called bacteriophages) living in the guts of people with inflammatory bowel disease (IBD) and healthy people. Researchers want to understand how these viruses differ and whether they can be grown in a lab to create a new treatment. The study invol…

This study will follow 100 people who need a stoma (an opening in the belly to pass stool) after surgery. Some will have their stoma site marked and get education before surgery, while others will not. The goal is to see if these steps improve quality of life and reduce problems …

This study compares a newer imaging method called TXI with standard dye-based imaging during colonoscopies in people with inflammatory bowel disease (IBD). The goal is to see which method better detects precancerous changes that can lead to bowel cancer. About 242 adults with IBD…

This study will use musculoskeletal ultrasound to look for hidden joint, muscle, and tendon inflammation in 81 people with inflammatory bowel disease (IBD) who have no known arthritis. The goal is to see how common these hidden problems are and to develop a standard ultrasound ch…

This study will use a detailed heart ultrasound technique called speckle tracking to look for early signs of heart trouble in 100 adults with inflammatory bowel disease (IBD). Researchers want to see if this method can catch heart changes before they become serious and how those …

This study looks at whether taking a daily vitamin D supplement (2000 IU) for 12 months can improve the health and quality of life of people with Crohn's disease or ulcerative colitis. Researchers will track how well participants stick to the supplement and measure their vitamin …

This observational study will follow 4500 adults with Crohn's disease or ulcerative colitis to identify biological markers—such as gut bacteria patterns—that predict disease progression and complications. Researchers will collect blood, stool, saliva, and tissue samples during ro…

This study looks at how eating salt affects gut health in people with Crohn's disease. Researchers will track salt intake and measure gut inflammation in 300 participants. The goal is to understand if a high-salt diet worsens symptoms and to improve dietary advice for managing th…

This study tests whether data from a wearable device and grocery loyalty cards can help detect disease flares in people with Crohn's disease or ulcerative colitis. Eighty adults will wear a smartwatch and use a store card to track their health and food purchases. The goal is to d…

This study uses computer simulations to better understand how a subcutaneous (under-the-skin) form of the drug infliximab works in people with inflammatory bowel disease (IBD) and rheumatoid arthritis. Researchers will analyze data from previous trials to create a model that pred…

This study will look at 150 infants and children aged 1 month to 4 years who are admitted to a hospital gastroenterology unit with a gastrointestinal disease. The goal is to find out how common electrolyte disturbances (like low sodium or potassium) are in these children. By meas…
