Summary

This study found that Platanus pollen is linked to allergies in some individuals, showing cross-reactivity with common foods like hazelnuts and bananas. These findings suggest a connection between pollen allergies and specific food sensitivities.

Area of Science:

  • Immunology
  • Allergology
  • Food Science

Background:

  • Established associations exist between tree/plant pollens and specific foods.
  • The study investigates potential cross-reactivity between Platanus pollen and foods of vegetable origin.

Purpose of the Study:

  • To verify cross-reactivity between Platanus pollen and vegetable foods.
  • To identify specific food allergens associated with Platanus pollen allergy.

Main Methods:

  • Cutaneous tests performed on 56 patients allergic to vegetable foods.
  • Statistical analysis to assess Platanus pollen association with foods and aeroallergens.
  • Specific IgE determination and RAST inhibition experiments for in vitro cross-reactivity verification.

Main Results:

  • Positive correlation observed between Platanus pollen and hazelnut, peanut, banana, and celery via skin tests.
  • RAST inhibition confirmed significant cross-reactivity between Platanus acerifolia pollen and hazelnut/banana.
  • Intermediate cross-reactivity was noted with celery and peanut.

Conclusions:

  • An association between Platanus pollen and specific vegetable foods (hazelnut, banana, peanut, celery) is identified.
  • In vitro IgE cross-reactivity supports the observed clinical associations.
  • Findings highlight potential cross-reactivity in pollen-food allergy syndromes.
