Epidemiology of non-IgE-mediated food allergies: what can we learn from that?

Abstract

Purpose of review: To underline the main characteristics of the non-Immunoglobulin E (IgE)-mediated food allergies (food protein-induced allergic proctocolitis food protein-induced enteropathy and food protein-induced enterocolitis syndrome ), which are common diseases in primary care and in allergy and gastroenterology specialty practices evaluating children.

Recent findings: Non-IgE-mediated food allergies comprise a spectrum of diseases with peculiar features affecting infants and young children. The most prominent features of these diseases are symptoms that affect mainly the gastrointestinal tract.

Summary: It is of paramount importance to provide the clinicians with the tools for non-IgE-mediated food allergy recognition in clinical practice to avoid the misdiagnosis with unnecessary laboratory tests and detrimental treatments.
