Could Bet v 1 affect sensitization molecular pattern in children?

Area of Science:

• Pediatric Allergy
• Immunology
• Molecular Diagnostics

Background:

• Allergy diagnosis relies on identifying specific IgE antibodies.
• Bet v 1, a PR-10 family allergen, is a common sensitizer.
• Pan-allergens can influence allergy testing results.

Purpose of the Study:

• To assess the effect of Bet v 1 sensitization on clinical symptoms in children.
• To correlate Bet v 1 sensitization with oral allergy syndrome (OAS) and anaphylaxis (ANA).

Main Methods:

• Analyzed serum IgE molecular components using the ISAC method.
• Included clinical data from 132 children (91 males, 41 females).
• Mean age of participants was 9.08 years.

Main Results:

• Bet v 1-sensitized children often showed co-sensitization to other PR-10 allergens.
• No significant IgE level differences were found between children with or without food allergy.
• No significant differences in IgE levels were observed between OAS and ANA groups, except for hazelnut allergy.

Conclusions:

• Bet v 1 sensitization affects sensitization patterns in children but doesn't predict clinical presentation.
• The study highlights the need for integrated diagnostic approaches beyond standard molecular allergy testing.
• Specific IgE assays are recommended to complement ISAC testing for precise clinical correlation.
