The pendulum between food protein-induced enterocolitis syndrome and IgE-mediated milk allergy

Abstract

The transition from milk protein-induced enterocolitis syndrome to IgE-mediated milk allergy is uncommon. Herein, we describe three infants that suffered from recurrent vomiting and restlessness in response to cow's milk formula with negative skin prick to milk and therefore diagnosed as milk protein-induced enterocolitis syndrome. After recovering and reintroducing cow's milk formula, they developed disseminated urticaria and positive skin prick test to cow milk compatible with IgE-mediated milk allergy.

Conclusion: An infant that recovers from cow milk food-induced enterocolitis syndrome might develop afterward IgE-mediated cow milk allergy.
