Food Allergies

Diagnosis

Indications for Testing

  • Medical history (pruritus, urticaria, gastrointestinal symptoms, angioedema anaphylaxis) indicating temporal association between food ingestion and symptoms (<2 hours), chronic diarrhea, and failure to thrive in children

Laboratory Testing

  • Two tests
    • Skin testing (pin prick) is no longer necessary, although generally less costly
    • Specific food serum IgE testing along with appropriate history – group or panel allergen tests may be helpful (ImmunoCAP appears to be best validated)
    • Neither test predicts severity of allergic reaction
    • Positive results may not be diagnostic – cross reactivity exists between proteins
    • Serum tryptase – elevated at 1-4 hours after anaphylaxis and can help confirm diagnosis
  • IgG testing has no proven validity
  • Food challenges
    • Should be performed as double-blind, placebo-controlled challenge
      • Must be done where resources are available to manage allergic reactions
    • Food challenges may be helpful but should not precede IgE testing
      • Administration of suspected food in gradually increasing doses
      • May be necessary if pin prick or IgE testing is negative and strong suspicion still exists for allergy 
    • May be dangerous to do food testing in certain patients with severe allergies
      • Should wait at least 2 years after a severe reaction to perform testing
  • Patch testing – typically used in non-IgE mediated food allergy (eg, eosinophilic esophagitis)
    • No standard reagent methods or interpretation available
    • Not recommended by the National Institute of Allergy and Infectious Diseases for routine evaluation

    Differential Diagnosis

Clinical Background

The National Institute of Allergy and Infectious Diseases defines food allergy as an adverse immune response occurring reproducibly on exposure to a given food and is distinct from other adverse responses to food, such as food intolerance, pharmacologic reactions, and toxin-induced reactions..

Epidemiology

  • Incidence
    • Varies by geographic region
    • Increased incidence reported over the past 10 years – especially peanut allergies
  • Age
    • Adults – <3% have food allergies
    • Children – up to 6% of children <3 years are affected; ~4% worldwide
  • Sex
    • M:F, equal

Risk Factors

  • History of asthma
  • Parent or sibling with a history of atopy, asthma, or food allergy

Pathophysiology

  • Any food can potentially sensitize the immune system and cause antibody production
    • Foods most likely to cause sensitivity include those that are
      • Water soluble
      • Heat resistant
      • Acidic
      • Proteolytic
  • Most food allergies are IgE mediated – may also be IgG mediated
    • 90% of IgE-mediated allergies are caused by cow milk, soy, chicken eggs, peanuts, tree nuts, wheat, fish, and crustaceans
    • Non-IgE-mediated reactions are also common to soy, wheat, and cow milk
  • Wheat, milk, egg, and soy allergies usually disappear gradually with age
  • Food intolerance does not equal food allergy

Clinical Presentation

  • Classic IgE-mediated (immediate hypersensitivity)
    • Reaction occurs within 1-2 hours after food is ingested
    • Classification
      • Oral allergy syndrome – pruritus, tingling, swelling of lips and palate after fresh fruit/vegetable 
        • Birch sensitivity – symptoms with raw carrots, celery, and apples
        • Ragweed sensitivity – symptoms with cantaloupe, watermelon, honeydew, and bananas
        • No symptoms when food is cooked
      • Gastrointestinal – nausea, abdominal pain, cramps, vomiting, diarrhea
      • Cutaneous – urticaria, angioedema, generalized pruritus, flushing, morbilliform rash
      • Respiratory – pruritus, tearing, nasal congestion, rhinorrhea, throat tightness, hoarseness, shortness of breath, dyspnea, wheezing
      • Cardiovascular – syncope, chest pain, arrhythmias, hypotension, shock
      • Neurologic – anxiety, headache, seizure, loss of consciousness
  • Mixed IgE/non-IgE
  • Non-IgE (cell-mediated)
    • Occurs ≥24 hours after food ingested
  • 80-85% of children outgrow food allergies by 5 years
  • Most persistent allergens are nuts, seeds, fish
    • Classification
      • Food protein-induced proctocolitis
        • Infants appear healthy
        • Blood-tinged stools in first 2-4 months of life
        • Usually secondary to milk or soy protein and most often in breast-fed infants
      • Food protein-induced enterocolitis syndrome
        • Infants appear ill
        • Bloody diarrhea, recurrent vomiting, failure to thrive
        • Most often secondary to milk and soy protein; rice, oat, other cereal grains, and chicken have also been implicated
        • Infants usually tolerate breast milk
