    Abstract:
    BACKGROUND: Atopic eczema and food allergy are common in early childhood. Children seem to gradually develop tolerance to milk and egg, and it is a relief for families when their child can tolerate small amounts of these basic foods, even if larger doses may still cause symptoms. AIM: To develop a model for low-dose oral food challenge, facilitating re-/introduction of milk or egg. METHODS: In 39 children sensitized to milk and/or egg, we performed 52 challenges using a new standardized model for low-dose oral food challenge. The recipes were validated for blinding with sensorial tests. RESULTS: Four children challenged to milk had a positive challenge outcome. There were no significant differences with respect to family history, associated atopic manifestations, nutritional supply, eczema severity, or skin-prick test compared with the non-reacting children, but total and specific IgE values were significantly higher. All but two of the non-reacting children were able to introduce milk and egg into their diet without problems. CONCLUSION: We report recipes and a protocol to be used for standardized open and double-blind placebo-controlled low-dose food challenge in young children, enabling the introduction of small amounts of egg and milk into the diet during tolerance development.
