Hyperbaric Oxygen Therapy for Ulcerative Colitis
open to eligible people ages 18-85
Chronic intestinal hypoxia and accompanying mucosal inflammation is a hallmark of ulcerative colitis (UC). Hyperbaric oxygen therapy (HBOT) involves breathing 100% oxygen under increased atmospheric pressure to increase tissue oxygenation. Two small prospective randomized controlled trials have demonstrated that the delivery of HBOT to UC patients hospitalized for acute moderate to severe flares results in improved remission rates and avoidance of in-hospital progression to biologics, small molecules, or colectomy. In this larger trial the study aims to confirm the treatment benefits of HBOT for hospitalized UC patients and study the immune-microbe mechanisms underpinning treatment response.

Prebiotics in Ulcerative Colitis
open to eligible people ages 18-85
The cause of inflammatory bowel disease (IBD) is currently unknown, although partly attributed to interactions among genetic risk polymorphisms, environmental factors, gut microbiome, and host immunity. Diet, particularly those with plant-based products, have been shown in prior research to improve gut microbial composition, which has been linked to different IBD-related outcomes. This study is interested in evaluating the impact of prebiotics on gut microbiome composition and gut health in patients with IBD. Dietary composition will be assessed at baseline and over the course of 16 weeks. Participants will be randomized to either consume an 8-week course of prebiotic supplementation beginning at week 0 or week 8. Stool samples will be collected at weeks 0 and 8. The stool will be analyzed for cross-sectional and longitudinal fecal microbial changes associated with different prebiotic and diet consumption patterns in the context of heterogeneous disease characteristics.

Dietary Composition in Crohn's Disease
open to eligible people ages 18-75
Patients with inflammatory bowel disease (IBD) often have narrowed microbial diversity and altered composition and function of the gut microbiome. We anticipate the anti-inflammatory diet, when compared with the usual diet, to produce favorable changes in these multi-omics profiles. These findings will provide insight into the interactions between diet and host biology, while providing clues on the mechanisms of diet therapy's effect and CD pathogenesis.

CDPATH™ to Help Manage and Treat Crohn's Disease
Sorry, in progress, not accepting new patients
CDPATH™ is a tool to help predict the potential for developing Crohn's disease related complications in certain adult participants within 3 years. The main aim of the study is to explore the use of CDPATH™ to describe a participant's risk profile and to have discussions with their doctor about the potential path of their Crohn's disease. The number of visits will be decided by the study clinic according to their standard practice.
