Respiratory symptoms in a child with IgE-non-dependent hypersensitivity to wheat.

Food allergy (FA) is a serious health problem, and its incidence has been increasing especially in children. Wheat is one of the five most common foods that trigger allergic reactions in children. It is an increasingly recognised trigger for immune-mediated FAs, both Immunoglobulin E (IgE) and non-IgE mediated. We describe the case of a 4-year-old boy with a combination of symptoms due to IgE-mediated asthma worsened by IgE-non-dependent hypersensitivity to wheat demonstrated by a positive patch test. With the avoidance of wheat oral intake, we observed a progressive clinical improvement. To the best of our knowledge, this is the first report of a patient with IgE-non-dependent allergy to wheat presenting with chronic symptoms in one body system outside of the gastrointestinal tract and with negative skin prick test. © BMJ Publishing Group Limited 2019.
