Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A mixture of milk powder containing 1.3 g cow's milk and wheat flour is baked in the oven for 30 min at 180 degrees Celsius. Each 60 g bread contains milk powder equal to 1.3 g cow's milk. Breads prepared for placebo include exactly the same ingredients except milk powder.
The placebo and cow's milk containing breads are supplied by the same manufacturer.
Patients' adherence is monitored by weekly phone calls and also by charts documenting daily consumpted bread amount, side effects and accidental dairy product consumption.


1. Active group: Receiving bread that contains 1.3 g baked milk, at least 60 g a day, for 12 months
2. Placebo group: Receiving bread with no milk, at least 60 g a day, for 12 months

Outcomes
Primary outcome [1] 295755 0
Tolerance, measured by double blind placebo controlled food challenge with raw cow's milk
Tolerance, measured by ability of raw cow's milk consumption without any adverse effects
Timepoint [1] 295755 0
baseline, 6 and 12 months
Secondary outcome [1] 316419 0
To evaluate tolerance induction by comparing following parameters at baseline, at 6 and 12 months of the study;
-skin prick test reactivity with raw cow's milk including different dilutions as 1/1, 1/100, 1/1000
-regulatory T cell proliferation response to raw cow's milk
-basophil activation test (CD63 expression) reactivity to raw cow's milk
-milk, casein, beta lactoglobulin specific IgA/IgG4/IgE levels
All those parameters will be assessed at baseline, 6 and 12 months of the study for all patients
Timepoint [1] 316419 0
baseline, 6 and 12 months

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Double blind placebo controlled food challenge (DBPCFC) with 1.3 g baked milk powder containing bread will be performed at the baseline for all participants.
Patients with no reactions will be included to the study, randomly as active or placebo group (central randomisation by computer). Daily consumption of baked milk will be provided during 12 months of period. The patients consuming bread with baked milk or with no milk will be assessed 6 and 12 months later with DBPCFC raw cow’s milk.
Patients continuing milk free diet will be assessed 6 and 12 months later with bread containing 1.3 g baked milk.
