Celery sensitivity: clinical and immunological correlations with pollen allergy

Area of Science:

• Allergy and Immunology
• Clinical Medicine

Background:

• Celery allergy is an IgE-mediated hypersensitivity.
• Patients often exhibit co-existing pollen allergies, particularly to mugwort and birch.

Purpose of the Study:

• To investigate the association between celery allergy and pollen sensitization.
• To identify clinical manifestations and diagnostic methods for celery allergy.

Main Methods:

• Study included twenty patients with confirmed celery allergy.
• Clinical symptoms were recorded, and allergy diagnoses were confirmed via skin tests and RAST.
• RAST inhibition assays were performed to explore cross-reactivity.

Main Results:

• A strong association was found between celery allergy and mugwort sensitization.
• A moderate association was observed between celery allergy and birch pollen sensitization.
• Common antigens between celery and pollens are suggested by RAST inhibition, though not fully characterized.

Conclusions:

• Celery allergy frequently co-exists with mugwort and birch pollen sensitization.
• IgE antibodies mediate celery allergy, diagnosable through skin and RAST tests.
• Cross-reactivity suggests shared antigens, warranting further investigation into their nature.
