Dr. Edmond Chan is a clinical investigator at the BCCH Research Institute and his research interests are in food allergy and eosinophilic esophagitis (EoE). As of Dec 2021, he has 148 peer-reviewed publications. Multi-centre national and international research studies include an oral cow’s milk immunotherapy clinical trial, several epicutaneous peanut immunotherapy clinical trials, national food allergy registries (peanut, seafood, etc), a national anaphylaxis registry, CHILD study birth cohort peanut allergy outcomes, national oral food challenge barriers & solutions, Health Canada study of emerging food allergens, national/international early peanut introduction implementation studies, and use of Epitope Mapping for food allergy diagnosis.
Local (including provincial) projects that have national extensions include our food allergy E-Health tool (Allergycheck.ca), food allergy-related anxiety, confidence with using epinephrine autoinjectors, allergy outcomes among premature infants, and selective/cost-effective use of component resolved testing for food allergy diagnosis. EoE specific projects together with Gastroenterology (Dr Vishal Avinashi) include: our unique EoE registry, EoE Biomarkers and epigenetic markers, the interaction between oral immunotherapy and EoE, organoids, EoEHSS (Histology scoring system), and T-cell assays for food triggers of EoE (and FPIES).
QI (Quality improvement) has been focused primarily on real-world pre-school peanut oral immunotherapy, which has expanded to multiple foods, cost-effectiveness, adherence (e.g. text messaging), virtual care, milk/egg ladders, and sublingual immunotherapy in older children. He has been an author on multiple clinical practice guidelines including CPS/CSACI and NIAID/National Institutes of Health) food allergy prevention guidelines, CSACI oral immunotherapy guidelines, and AGA/Joint Task Force EoE guidelines.

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.
