This study looks at gut bacteria and related chemicals in 120 adults to understand why inflammatory bowel disease (IBD) and depression often occur together. Researchers will compare people with both conditions, those with IBD only, and healthy volunteers. The goal is to find uniq…

This study looks at whether the unique mix of bacteria and fungi in the gut can predict how well Crohn's disease patients will respond to treatment. Researchers will collect stool, blood, and tissue samples from 100 adults during routine colonoscopies and track their health for a…

This research study collects health information from 10,000 people with brain inflammation conditions like Long COVID, ME/CFS, and autoimmune diseases. Participants use a smartphone app to share symptoms, health history, and wearable data. The goal is to find disease subtypes and…

This study is creating a large database to collect information on people with rare diseases like amyloidosis, sarcoidosis, and Gaucher disease. Researchers will track patients' health over time, including their symptoms, treatments, and outcomes. The goal is to improve diagnosis …

The PLANET study is looking at whether tiny plastic particles in our environment can trigger gut inflammation and raise the risk of inflammatory bowel disease (IBD). Researchers will measure microplastics in stool samples from pregnant women, their healthy relatives, and people w…

This study explores how traditional Chinese medicine tools, such as tongue and pulse diagnosis, can help identify unique features of inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. Researchers will compare 30 people with IBD to 30 healthy volun…

This study looks at a common problem after bowel surgery called postoperative ileus, where the bowel temporarily stops working. The researchers want to test a scoring system called IFEED to see if it can better define this condition and predict how long patients stay in the hospi…

This study looks at how natural cannabis compounds (phytocannabinoids) affect immune cells from 100 people with chronic inflammatory diseases like rheumatoid arthritis, lupus, and Crohn's disease. Researchers will take a blood sample and expose the cells to different cannabis ext…

This study looks at whether a toxin called deoxynivalenol (DON), found in grains, might be a risk factor for inflammatory bowel disease (IBD). Researchers will measure DON levels in 100 people—some with Crohn's disease and others without IBD—to see how the body processes it. The …

This study is testing whether robotic surgery is a practical option for people with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. Researchers will compare robotic surgery to standard laparoscopic surgery in 100 adults to see which approach wo…

This study looks at 120 people with various immune deficiencies to see if a chronic gut virus infection is tied to liver or digestive problems. Researchers will collect blood, stool, urine, and biopsy samples to screen for enteric viruses. The goal is to identify which patients a…

This study follows 216 adults with inflammatory bowel disease (IBD) who are in remission. They wear a wrist monitor and fill out sleep questionnaires for one year to see if changes in sleep quality can predict when a flare-up will happen. The goal is to find early warning signs o…

This study compares two types of minimally invasive surgery—robotic and laparoscopic—for people with inflammatory bowel disease (IBD) who need colorectal surgery. Researchers want to see which approach leads to fewer complications, less pain, and faster recovery. About 110 adults…

This study uses MRI scans to look at bone marrow fat in teenagers newly diagnosed with Crohn's disease, comparing them to healthy teens. The goal is to understand if Crohn's affects bone health early on. Researchers will also measure bone density using other imaging methods. The …

This study is testing a new device called a wireless thermal capsule, which is swallowed and measures temperature as it travels through the digestive tract. The goal is to see if it can reliably detect small temperature changes that might indicate inflammation from diseases like …

This study is for adults in South Korea with ulcerative colitis or Crohn's disease who are already taking vedolizumab injections. Researchers will look at medical records to track side effects and how well the treatment works. No new medicine or treatment is given—this is just an…

This study looks at whether microplastics are found more often in children with inflammatory bowel disease (IBD) compared to healthy children. Researchers will collect samples of tissue, blood, urine, and stool from 40 children during routine endoscopy. No treatment is given—the …

This observational study will follow 1,000 pregnant women with inflammatory bowel disease (IBD) who are taking newer medications (non-anti-TNF biologics or targeted small molecules). Researchers will track serious infections and other adverse events in mothers and their children …

This study is a large registry that will collect information from over 4,000 people with Crohn's disease or ulcerative colitis in Argentina. Doctors will record details about patients' diagnosis, treatments, and any safety issues like infections. The goal is to better understand …
