Background:

Allergy to cow’s milk protein is a common problem in children. The clinical manifestations of the reactions that are mediated by IgE are varied and the anaphylactic reactions can be life-threatening.

Clinical case:

A girl at an age of four months and a half that, five minutes after consuming cereal with cow’s milk, had rashes in the perioral area and extensive pruritic micropapular lesions associated with vomit and inspiratory stridor. She received adrenaline by intramuscular injection and antihistamines by intravenous injection. She was first evaluated in a service of allergy treatment when she was six months and twenty days old. The results of the allergen-specific immunoglobulin E test were positive. The treatment was initiated with a hydrolyzed rice formula and supplementary feeding.

Conclusions:

Anaphylaxis can be the first and last manifestation of a food allergy. The right education for parents about strictly avoiding the food that triggered the allergic reaction and the right training in the use of intramuscular adrenalin may result in a better prognosis for patients.
