Mucosal Innate Immune Activation in Chronic Intestinal Disorders
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Crohn's disease and ulcerative colitis are types of chronic intestinal disorder called inflammatory bowel diseases (IBD) that can affect the small and large bowel causing symptoms of abdominal pain, diarrhea, blood in the stool, and weight loss. Irritable bowel syndrome (IBS) is a milder form of IBD, with symptoms of abdominal pain, bloating, diarrhea or constipation, and blood in the stool. It is not known what causes diseases such as IBD and IBS. This study will look at the events in the gut that leads to leaky gut and inflammation in patients with IBD and IBS. The study will also see if medications such as rifaximin and mesalamine may reduce the amount of leaky gut.
1) Patients scheduled for endoscopy (EGD or colonoscopy) for IBD will be consented to allow physicians who are performing endoscopies to take additional biopsies and blood samples for "research purposes".

Sexes Eligible for Study:
Accepts Healthy Volunteers:
The subject population includes patients with known Crohn's disease, ulcerative colitis and indeterminant colitis. Patients will be recruited after they check in to the endoscopy unit, and before their endoscopic procedure, prior to any pre-procedure sedation medications having been given. All participants are undergoing endoscopy with biopsy for surveillance, screening, , diagnosis , or assessment of treatment. If no biopsy specimens are taken from subjects for diagnosis, no biopsy samples are taken for research purposes. The subject enrollment goal is 60 separate subjects with Crohn's disease, ulcerative colitis and indeterminant colitis or Irritable bowel syndrome. The subjects' participation will be limited to in the endoscopy suite.
Men and women, 18-years old and older
Presenting at the University of Arkansas for Medical Sciences (UAMS) Endoscopy center to undergo endoscopy with biopsy for surveillance, screening or diagnosis.
