Evaluating food allergy thresholds and predictors
Thresholds In Food Allergy evaluaTion And predictioN, a Prospective, Multicentre Registry Study
This study is trying to see how much of certain foods can trigger allergic reactions in people with food allergies in Canada and what factors might affect how severe those reactions are.

What this trial studies
This observational registry aims to quantify food allergy thresholds in Canada and identify their clinical predictors. Participants with a suspicion or history of food allergies will undergo oral food challenges to assess their reactions. The study will collect data on symptoms and test results to better understand the factors influencing food allergy severity. By analyzing this information, researchers hope to improve diagnosis and management of food allergies.
Who should consider this trial
Good fit: Ideal candidates include individuals with a suspected or confirmed history of food allergies who can safely participate in oral food challenges.
Not a fit: Patients with previous desensitization treatment to food allergens or those with unstable medical conditions may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to better diagnosis and management strategies for patients with food allergies.
How similar studies have performed: Other studies have shown success in evaluating food allergy thresholds, indicating that this approach is supported by prior research.
Eligibility criteria

Inclusion Criteria: 1. Suspicion or history of food allergy based on medical history, positive skin prick test, and/or serum food-specific IgE. A suggestive history is defined as typical clinical signs and/or symptoms (urticaria, angioedema, abdominal pain, vomiting, dyspnea, wheeze) within 60 minutes of the ingestion of a food. 2. Ability to discontinue all antihistamines for 1 week before oral food challenge. Exclusion Criteria: 1. Previous desensitization treatment to a food allergen 2. Allergies to any component of the oral challenge vehicle 3. Unstable conditions including uncontrolled asthma or chronic urticaria 4. Any clinically significant disease/chronic medical condition which may interfere with study evaluations.
