Spatial gene study for inflammatory bowel disease

This study looks at the genes of people with inflammatory bowel disease (IBD) and healthy volunteers to understand why IBD affects different populations. You may join if you have Crohn's disease, ulcerative colitis, or undetermined IBD, or if you are a healthy person without any IBD history.

This study is looking at how the immune system works in people with inflammatory bowel disease (IBD), which includes conditions like Crohn's disease and ulcerative colitis. By comparing blood or tissue samples from people with and without IBD, researchers hope to find better ways to treat the disease in the future.

This study collects blood and tissue samples to better understand how the immune system behaves in people with inflammatory bowel disease (IBD), which includes Crohn's disease and ulcerative colitis. It aims to advance research rather than test a specific new treatment, and it also enrolls healthy volunteers for comparison.

This study collects samples to learn how gut microbes, genetics, and body chemistry may relate to Crohn’s disease or ulcerative colitis. Your information and samples may help researchers understand disease patterns, but it does not test a new drug.

This study looks at how changes in gut bacteria (the microbiome) relate to inflammatory bowel disease, including ulcerative colitis and Crohn disease. It may help researchers understand what might improve symptoms or disease control.

This study looks at blood and/or tissue “molecular” (cell-level) reasons why treatments don’t fully work in adults with Crohn’s disease or ulcerative colitis. If you are starting a biologic or small-molecule medicine and still have moderate to severe symptoms, you may be able to contribute to research that helps improve future care.
