The Physician's Guide to Laboratory Test Selection and InterpretationFood 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
- Food testing
- 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
- Needs to be performed under controlled circumstances with very specific endpoints
- Double-blind testing – considered gold standard
- Food challenges may be helpful but should not precede IgE 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
- Carcinoid syndrome
- Celiac disease
- Giardia duodenalis
- Gustatory rhinitis
- Inflammatory bowel disease
- Lactase deficiency
- Scombroid poisoning – most cases from tuna, mahi-mahi, and swiss cheese
- Sulfate ingestion
Clinical Background
Food allergies are a common form of allergic presentation in childhood. 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% with allergies
- Usually in children – as much as 6% of children <3 years are affected
- Sex
- M:F, equal
Risk Factors
- History of asthma
- Parent or sibling with a history of atopy or asthma
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
- Foods most likely to cause sensitivity include those that are
- Most food allergies are IgE mediated but may also be IgG mediated
- 90% of IgE-mediated allergies are caused by just eight foods – 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 is not the same as food allergy
Clinical Presentation
- Classic IgE-mediated (immediate hypersensitivity)
- Reaction occurs within an hour 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, dysrhythmia, hypotension, shock
- Neurologic – anxiety, headache, seizure, loss of consciousness
- Oral allergy syndrome – pruritus, tingling, swelling of lips and palate after fresh fruit/vegetable
- Mixed IgE/non-IgE
- Occurs 1-24 hours after food is ingested
- Classification
- Atopic dermatitis
- Eosinophilic esophagitis/gastroenteritis
- 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
- Food protein-induced proctocolitis
Treatment
- Avoid foods that cause allergic reaction
- Requires careful reading of package labels, especially for those with nut allergies
- Many products are coproduced in factories where nut residue may be present
- Warnings on packages do not correlate with actual risks
- Requires careful reading of package labels, especially for those with nut allergies
- Patients with documented severe food allergies or children with allergies and coexistent asthma must have epinephrine kits readily available
- Allergen immunotherapy – associated with significant adverse side effects (desensitization)
Prevention
- Avoid cow milk and dairy products until 6 months old
- Suggest breast feeding
- Soy-based formulas have no role in prevention
- Avoid supplemental feeding and solid foods until 6 months old
