CAMEL

Study hypothesis

Probiotic supplementation in young infants (first 2 years of life) has a therapeutic effect, associated with upregulation of tolerance for cow's milk allergens, as well as combined with local and systemic immunomodulation and improvement of allergic manifestations in the gut, skin and airways.

Ethics approval

Ethics approval received from the local medical ethics committee

Study design

Multicentre, randomised, double blind, placebo controlled, parallel group trial

Patient information sheet

Condition

Allergy to cow's milk

Intervention

In children with cow's milk allergy diagnosed by an elimination-challenge test (open), the longitudinal development will be followed from inclusion (less than age 6 months) during 18 months. All participants will receive a hydrolysed formula (caseïne hydrolysate, Allergycare®, Friesland Foods). Two probiotic strains (one lactobacillus and one bifidobacteria) will be added to the Allergycare® in 50% of the participants, as intervention for 12 months, randomised, double-blind.

Primary outcome measures

Development of tolerance for cow's milk, observed by a challenge test (double blind) after 12 months of treatment.

Secondary outcome measures

1. The severity of cow milk allergy related features, namely variables on physical inspection, as well as observed features by the parents in a questionnaire/diary
2. Assessment of skin features will be performed by the objective SCORAD, as a measure for the severity of atopic dermatitis
3. Need for medication
4. Quality of life, as judged by the parents and noted in a questionnaire/diary
5. Weight and height
6. Effects on immuno(dys)regulation; on sensibilisation, namely allergen-specific IgE and epitope-specific IgE, T-lymfocyte subsets, as measured by membrane markers, signal-transduction proteins related to immunomodulation, In-vitro allergen–stimulated T-lymphocyte activity with specific cytokine detection
