Exacerbation of Eczema and History of Food Allergy

  • Elena Camelia Berghea

Practical Points

  • Primary food allergy mainly affects young children

  • Primary food allergy is caused by class I food allergens which are heat-stable and resistant to degradation or proteolytic digestion, having the potential to induce severe reactions

  • Adults frequently develop food allergy as a consequence of an inhalant sensitization, with class II allergens

  • Class II allergens are easily degradable food allergens that tend to induce milder reactions, often limited to oral allergy symptoms

  • The presented case was an example of polysensitivity to food and respiratory allergens in a child with atopic dermatitis

  • Molecular component diagnosis is useful in identifying sensitization to major and minor allergens and possible cross-reactivity, when several food and respiratory allergies are present
