Area of Science:

  • Allergen immunotherapy
  • Allergic rhinitis research
  • Immunology

Background:

  • Nasal allergen challenges simulate allergic rhinitis, revealing cellular kinetics and interactions.
  • Measuring cell-specific soluble mediators aids diagnosis and immunotherapy monitoring.

Purpose of the Study:

  • To present data on eosinophil cationic protein and tryptase levels post-nasal allergen challenge.
  • To evaluate the long-term influence of specific immunotherapy on nasal peak flow.

Main Methods:

  • Nasal allergen challenges were performed.
  • Measurements of eosinophil cationic protein and tryptase were conducted.
  • Nasal peak flow was assessed before and at 1, 2, and 3 years after immunotherapy initiation.

Main Results:

  • Data on eosinophil cationic protein and tryptase levels after nasal allergen challenge are presented.
  • The impact of specific immunotherapy on nasal peak flow over three years is analyzed.

Conclusions:

  • Nasal allergen challenges are valuable for studying allergic rhinitis mechanisms.
  • Mediator measurements and nasal peak flow monitoring provide insights into immunotherapy effectiveness.
