Prevention of food allergy – skin barrier interventions

Abstract

The relationship between infant skin health and food allergy pathogenesis is the focus of intense research activity, on the basis that interventions to improve infant skin health may potentially lead to the prevention of food allergy. Current evidence does not provide conclusive findings on the mechanisms of food allergy development but does support the possibility that food allergy develops through transcutaneous sensitisation to allergenic peptides. In this article, we review the evidence for this model of food allergy development, assess strategies currently being tested for prevention of food allergy through cutaneous interventions, and identify key knowledge gaps which might be explored in future work.
