Food Allergies in Children Dr C Macaulay Dr C Lemer Dr R Bhatt

Background Food allergy may be confused with food intolerance Food allergy can be classified into IgE-mediated and non-IgE-mediated reactions. IgE-mediated reactions are acute and frequently have a rapid onset. Non-IgE-mediated food allergy is frequently delayed in onset. Most common foods causing allergies • fish • hens' eggs • kiwi fruit • peanuts and tree nuts • sesame • shellfish • soy • wheat.

Epidemiology The prevalence of food allergy in Europe and North America has been reported to range from 6% to 8% in children up to the age of 3 years. Only 25–40% of self-reported food allergy is confirmed as true clinical food allergy by an oral food challenge

Focused history A personal or family history of atopy is the most significant predictor of allergy. Ask about history of the reaction Timing likely precipitants. Include history of eczema, asthma, Gastroesophageal reflux Note that the absence of signs or symptoms does not exclude a food allergy Taking a good history is key to diagnosis

Immediate reactions -IgE mediated  Occur within 2 hours of contact or ingestion Symptoms are consistent and reproducible and include rashes, itching, wheeze, GI symptoms, angioedema and anaphylaxis Skin prick tests (or blood tests for specific IgE antibodies to allergens/likely co-­‐allergens) can help diagnosis

Treatment in IgE Mediated Exclusion Should have dietician advice Should have an EpiPen if history of anahylaxis or have food allergy and asthma

Delayed reactions – Non IgE mediated  Occur > 2hrs after ingestion but within 2-­‐3 days Often difficult to reproduce and symptoms less specific May present: eczema, colic, reflux, loose stools, constipation, food aversion No tests help diagnosis

Treatment Non IgE mediated Treatment is 2-­‐6 week trial of exclusion of the suspected food followed by reintroduction If cows milk protein allergy suspected – see GOR guideline

When to refer has had an anaphylactic reaction had one or more severe delayed reactions has immediate or delayed allergic reactions to multiple allergens or food groups, especially if there is faltering growth has had acute allergic reaction with coexisting asthma moderate – severe eczema where cross reactive or multiple food allergies suspected has not responded to a single –allergen elimination diet Or: There is strong clinical suspicion of Ig E-­‐mediated food allergy but allergy test results are negative

Top Tips All children who are excluding multiple foods should be referred to a paediatric dietician Most cases of urticaria lasting over several days are associated with a viral infection and do not represent a food allergy Do not use serum-­‐specific IgE testing to diagnose delayed food allergy Allergy UK : www.allergyuk.org/ has excellent advice sheets for families and clinicians
