[How reintroduce food in an allergic child]

How reintroduce food in an allergic child. Many food allergies heal when the child grows. The management is very different, if the allergy recognizes a non-IgE-mediated mechanism or IgE-mediated. In case of food allergy with non-IgE mediated mechanism reintroduction can sometimes be gradual at home. If IgE mediated allergy, monitoring the size of the prick tests screw the evolution of specific IgE indicates the appropriate time for the practice of a food challenge. If the allergy persists over time, oral immunotherapy is an important change in the food allergy treatment paradigm. However, to date, the recommendations advise against the practice outside of research protocols. Two exceptions are discussed: some allergies not IgE mediated and egg or cow's milk cooked immunotherapy.
