Early allergy diagnosis in children is crucial. Testing multiple allergen-specific immunoglobulin E (IgE) antibody levels, rather than single tests, can improve diagnosis and management of allergic march progression.

Area of Science:

  • Immunology
  • Allergy Research
  • Pediatric Medicine

Background:

  • The 'allergic march' describes the progression of allergic diseases in individuals over time.
  • Children not progressing through the allergic march may face increased risks of adult allergic diseases.
  • Early allergy diagnosis in children is therefore essential for timely intervention.

Purpose of the Study:

  • To evaluate the efficacy of multi-allergen testing for early allergy diagnosis in children.
  • To explore the relationship between allergen load and allergic disease severity.
  • To identify improved diagnostic strategies for managing the allergic march.

Main Methods:

  • Quantification of immunoglobulin E (IgE) antibodies against a profile of airborne and food allergens.

  • Utilizing a threshold of sum of IgE antibody concentrations (>=3.5 kUA/l) combined with the number of positive allergen tests.
  • Assessing the correlation between allergen load and the severity of co-existing allergic diseases.

    • Main Results:

    • A single positive IgE antibody result may be less efficient for diagnosis than a multi-allergen profile.
    • A combined approach using IgE levels and the number of positive allergens shows potential for improved diagnostic accuracy.
    • Higher allergen loads are associated with increased severity of allergic diseases.

    Conclusions:

    • Multi-allergen IgE testing, considering both concentration and number of positive responses, offers a more efficient diagnostic approach for children.
    • Reducing the overall allergen load is a critical component of successful allergic disease management.
    • This strategy aids in identifying children at risk and managing their allergic march effectively.
