- Overview
-
There is increasing evidence to suggest diet plays an important role in inflammatory bowel disease by impacting the gut microbiome and affecting the barrier function of the gut (protective mucus layer and intestinal epithelial tight junctions). In our studies we are looking at the role of various diets and the impact they have on the clinical outcome and quality of life for our patients. We are also assessing the impact diet therapies have on the gut microbiome and immune regulation receptor pathways within the body.
We have also been assessing the immune response to vaccinations in patients with IBD on immunosuppression therapy.

A safer treatment path for high-risk children to overcome food allergies
New research from BC Children’s Hospital Research Institute and UBC reveals a safe path to overcoming food allergies for older children or building resistance for those who can’t risk consuming allergens. It’s called sublingual immunotherapy (SLIT), and it involves placing small amounts of food allergens under the tongue.
