Paediatric non-IgE mediated food allergy: guide for practitioners.

AIM:Food avoidance in children is increasingly common due to concerns about allergy. We aim to review the current literature on paediatric non-IgE mediated food allergy including what is known about pathophysiology, diagnosis, management and prognosis of common and severe presentations. Considerations regarding appropriate formula selection are also presented. METHODS:Common non-IgE mediated conditions were searched through common medical databases. Thorough review of available literature was then synthesised and critically appraised. RESULTS:Current understanding of immunological mechanisms of most non-IgE mediated conditions remains elusive. Most conditions are outgrown in childhood and have a good prognosis. Dietary modification for some conditions is important to ensure safety. They are not recommended in all situations due to potentially harmful consequences. CONCLUSION:Assessment of children with concerns regarding non-IgE mediated conditions requires a thorough history and is generally not supported by reliable diagnostic tests. Caution is warranted when advising families to undertake dietary exclusions unless well supported by the evidence and ensuring benefits outweigh any potential harm.
