NCT05662800

Brief Summary

The aim of the study is to assess the prevalence of peanut, tree nuts, and sesame allergy in Polish children at high risk of food allergy. Additionally, the timing of the development of peanut, tree nuts and sesame allergy in the first three years of life in a high-risk population will be assessed.

Outcome Measures

Primary Outcomes (1)

  • The prevalence of peanut, tree nut and sesame allergy in Polish children with high risk of food allergy

    Based on data related to allergen consumption, SPT, and OFC, patients will be classified as allergic to peanuts and sesame or non-allergic. Based on the results of SPT, sIgE, and OFCs are performed in exceptional situations, patients will be classified as allergic, non-allergic, or likely not allergic to selected tree nuts.

    1-2 days

Other Outcomes (1)

  • The timing of the development of peanut, tree nuts and sesame allergy in the first three years of life in a high-risk population

    2 years

Interventions

Children will undergo skin prick testing with the following allergens: commercial extracts for peanut, hazelnut, almond, cashew, pistachio, walnut, macadamia, sesame, Timothy grass, and birch pollen; positive and negative control; peanut butter and tahini (sesame) paste. Specific IgE levels will be quantified to all the above-listed tree nuts, peanuts, sesame seed and peanut components (Ara h 1, Ara h 2, Ara h 3, Ara h 6, Ara h 8, Ara h 9). Children will undertake cumulative or incremental oral food challenge with peanut, sesame and tree nuts, depending on the risk assessment based on patient's medical history and results of diagnostic tests.

Eligibility Criteria

Age4 Months - 36 Months
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)
Sampling MethodNon-Probability Sample
Study Population

The children will be recruited using mailing to general paediatric, allergy, and dermatology practices and directly to two allergy centers (Warsaw and Bydgoszcz).

You may qualify if:

  • moderate or severe eczema and/or egg allergy,
  • at least one complementary food already introduced,
  • signed informed consent.
  • Assessment of eczema severity: Eczema severity will be assessed based on the objective SCORing Atopic Dermatitis (SCORAD), use of topical steroids, calcineurin inhibitors or systemic treatment as well as history of hospital admission.
  • Definition of egg allergy: Participants with a documented IgE-mediated egg allergy will be identified by a convincing history of a reaction in the presence of a positive skin prick test (SPT) (wheal diameter of 3 mm or greater with egg white extract) or an SPT ≥ 5mm with no history of a reaction.

You may not qualify if:

  • inability to withdraw antihistamines for at least 5 days prior to testing,
  • use of prohibited medication such as beta-blockers, angiotensin-converting-enzyme inhibitors (ACE-I) and biological treatments affecting the immunological response,
  • uncontrolled asthma or eczema which does not warrant readiness for a food challenge within the study time frame,
  • chronic urticaria,
  • chronic systemic diseases.
