Pathophysiology of Non-IgE-Mediated Food Allergy.

Non-IgE-mediated food allergies are a group of disorders characterized by subacute or chronic inflammatory processes in the gut. Unlike IgE mediated food allergies that may result in multi-organ system anaphylaxis, the non-IgE mediated food allergies primarily affect the gastrointestinal tract. This review outlines the clinical manifestations, epidemiology, pathophysiology, and management of non-IgE-mediated food allergies.

The importance of early peanut ingestion in the prevention of peanut allergy.

Peanut allergy appears to have increased in prevalence, is often severe and is typically life-long. Therefore, reducing its incidence through a primary prevention strategy is a priority. Guidelines on peanut introduction have evolved with time and given evidence of peanut allergy risk reduction with early infant ingestion exposure, the current US advice promotes early introduction for infants, particularly targeting those at highest risk.

Food Protein-Induced Enterocolitis Syndrome: a Comprehensive Review.

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE-mediated food allergy that has been well-characterized clinically, yet it is still poorly understood. Acute FPIES is characterized by vomiting 1-4 h and/or diarrhea within 24 h after ingestion of a culprit food. Chronic FPIES is the result of chronic exposure to an offending food that can result in chronic watery diarrhea, intermittent vomiting, and failure to thrive.
