Brief abstract of project and relevance

Celiac Disease (CD) is an autoimmune condition that affects the gastrointestinal tract, and is triggered by the ingestion of gluten, a protein found in wheat, rye, and barley. Life-long adherence to a strict gluten-free diet (GFD) is the only treatment. CD is estimated to occur in 5-7% of type 1 diabetes (T1D) patients. CD screening in Ontario diabetes practices is not universal. Also, clinical guidelines advise screening for CD in symptomatic T1D patients, which has led to confusion regarding best practice.

Currently, no consensus exists on the optimal way to manage asymptomatic patients with CD and T1D, which share common autoimmune origins. The impact of dietary treatment as it pertains to clinically relevant outcomes, such as metabolic control, bone mineralization and wellbeing will be evaluated in this study. A randomized controlled study longitudinally evaluating HbA1c and glycemic excursions using CGM will rigorously determine the impact of a GFD on blood glucose variability in patients with T1D.

Screening is ongoing across the Greater Toronto Area and Ontario.
