Guide Disease Management of CHDs With ImmunoCAP

 

What the profile will tell you
The ImmunoCAP Allergy March profile has been developed to answer three questions:

  1. Are the patient’s symptoms caused by atopy or not?

  2. What allergens are responsible?

  3. Where is the patient on the food/inhalant sensitization continuum
    (the Allergy March)?

This profile consists of 11 carefully selected food and inhalant allergens. More than 90% of childhood food sensitivities result from 6 allergens1 so the ImmunoCAP Allergy March profile covers these (and includes fish). In addition, the profile contains the following inhalant allergens: dog and cat dander, cockroach, mold, and house dust mite. These key allergens were selected to aid in detecting sensitivities most often proven to cause acute allergic disease in children, and to drive the progression of disease severity involved in the Allergy March.2

Treatment considerations
Whether the symptoms are eczema, GI distress, recurrent otitis media, rhinitis, or asthma, there is a chance the patient suffers from underlying allergic disease. 2,3 If the ImmunoCAP results are negative, the symptoms most likely don’t have an underlying atopic basis, and should be managed with symptomatic treatment. If the ImmunoCAP results are positive, other treatment alternatives become possible.

Atopic Dermatitis
While avoidance of food allergens has risk relative to nutrition, high IgE levels (for example, above 5 kUA/L) suggest exploring elimination diets, but care should be exercised to maintain adequate nutritional levels; specialist referral is recommended.4

In the case of atopic dermatitis (eczema, with a proven underlying atopic etiology), topical steroid treatment can provide relief and antihistamines will target the underlying allergic inflammation and itching.4 Nonsedating antihistamines (eg, Zyrtec®, Claritin®) may be used, and because pruritus often occurs at night, sedating antihistamines (hydroxyzine, diphenhydramine) are suggested for use at bedtime.5

GI Distress
The literature reports five major GI symptoms with a possible allergic basis6:

  1. colic
  2. constipation
  3. vomiting
  4. reflux
  5. diarrhea

While these are not uncommon childhood conditions, understanding whether or not these conditions have an underlying atopic etiology, and understanding whether the patient may be “on” the Allergy March are important. Avoidance of offending foods (elimination diet) may be trialed, but care should be exercised to maintain adequate nutritional levels; specialist referral is recommended.4

Recurrent Otitis Media
Acute otitis media (AOM) is generally the result of bacterial infection, so treatment with antibiotics may be warranted.7 However, recurrent bouts of AOM may suggest eustachian tube dysfunction, compounded by an underlying allergic condition (especially allergic rhinitis [AR]). Experts therefore recommend allergy testing to confirm atopy and treatment of comorbid AR to aid control of otitis media.4,7
