Description
Inclusion Criteria:
- A history suggestive of immediate allergy to the food. A convincing clinical history of an IgE mediated reaction to a specific food will be defined as a minimum of 2 mild signs/symptoms or 1 moderate or 1 severe sign/symptom that was likely IgE mediated and occurred within 120 minutes after ingestion or contact
The presence of at least one of the following confirmatory tests:
- Positive SPT to the culprit food allergen (weal diameter 3 mm larger than that of the normal saline control). The allergens used will be commercial extracts of the foods (Omega Labs, Toronto, Ontario).
- Detection of serum specific IgE (>0.35 kU/L) to the culprit food or any of its proteins, measured by fluorescence enzyme immunoassay (Phadia, CAP System, Uppsala, Sweden).
Exclusion Criteria:
- Patients who have uncontrolled respiratory disease (asthma, cystic fibrosis, etc.)
- Patients who present with intercurrent disease active at the time of starting desensitization.
- Non IgE mediated or non-immunological adverse reactions to milk or peanuts.
- Malignant or immunopathological diseases and/or severe primary or secondary immune deficiencies.
- Patients receiving oral immunosuppressor therapy.
- Patients receiving β-blockers (including topical formulations), or who receive daily doses of NSAIDs, aspirin or ACE inhibitors for cardiac issues.
- Associated diseases contraindicating the use of epinephrine: cardiovascular disease, severe hypertension or hypotension.
- Patients diagnosed with eosinophilic gastrointestinal disorders, including patients with a history of antacid use for reflux related to food impaction or with a history of esophageal spasm.
- Patients already tolerating processed/cooked forms of the food (e.g.,baked goods with milk).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Standard Protocol - High Dose Arm
Subjects will progress through desensitization to a high maintenance dose - 1200 mg of crushed peanut, 200 ml of milk or 1200 mg of egg powder.
|
Participants consume increasing doses of allergenic food daily until they reach a maintenance dose. In the case of the High Dose Arm, participants will progress to a daily dose of either 1200 mg, 300 mg or 200 ml of egg, peanut or milk respectively. Participants randomized to the Low Dose Arm also begin by consuming small amounts of the allergenic food, gradually increasing the daily dose. However, participants in this group only progress to 300 ml, 30 mg or 50 ml daily dose of egg, peanut or milk respectively. The Cooked/Transformed Allergen Arm begins the desensitization with a cooked or transformed form of the allergen - muffins in the case of egg or milk, Bamba puffs in the case of peanut. Participants take increasing amounts of these products (one muffin for egg and milk and four Bamba puffs for peanut) then transition to egg, milk or peanut. Participants then continue their dose progression, getting to 1200 mg, 200 ml or 300 mg for egg, milk and peanut respectively. |
Experimental: Modified Protocol - Low Dose Arm
Subjects will progress through desensitization to a low maintenance dose - 120 mg of crushed peanut, 50 ml of milk or 300 mg of egg powder.

Participants then continue their dose progression, getting to 1200 mg, 200 ml or 300 mg for egg, milk and peanut respectively. |
Experimental: Modified Protocol - Cooked/Transformed Allergen Arm
Subjects will begin desensitization with cooked versions of the allergen (muffins in the case of egg and milk) or transformed versions (Bamba puffs for peanut).
They will progress up to a full muffin or 4 Bamba puffs (for egg/milk and peanut respectively).
Once subjects have reached these doses, they will transition to doses of pure allergen.
They will then progress to the same top dose as subjects in the High Dose Arm.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of anaphylaxis in different Oral Immunotherapy protocols
Time Frame: 3 years
|
Do participants in the different study arms experience similar rates of anaphylaxis during their participation in the study?
Anaphylaxis is defined as an allergic reaction to the food the subject is allergic to, that involves symptoms in two of the following organ systems: skin, respitratory, gastro-enterologic or neurologic.The Consortium for Food Allergy Research (CoFAR) grading scale will be used for assessing severuty of allergic symptoms

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Efficacy of different Oral Immunotherapy protocols
Time Frame: 3 years
|
Do participants in the three study arms experience similar levels of desensitization to their allergen?
This will be assessed by a Double-Blind Placebo Controlled Oral Food Challenge (DBPCFC).
Doses of allergen that elicit symptoms strong enough to end the challenge will be compared between the three groups.
Symptom severity will be graded using the CoFAR grading scale.
