Flower handling causes allergic reactions like asthma and urticaria in industry workers. Skin prick tests and RAST confirm allergies, often leading to career changes due to cross-sensitization.

Area of Science:

  • Allergy and Immunology
  • Occupational Health

Background:

  • Occupational exposure to flowers can trigger allergic symptoms.
  • Flower industry workers are at risk for developing allergic diseases.

Purpose of the Study:

  • To investigate flower-induced allergies in 14 patients.
  • To evaluate diagnostic methods for flower allergy.
  • To identify cross-reactivity patterns.

Main Methods:

  • Case series of 14 patients with flower-related complaints.
  • Skin prick tests (SPT) using homemade pollen extracts.
  • RAST testing for specific allergens (mugwort, chrysanthemum, Solidago).

Main Results:

  • Allergic rhinoconjunctivitis, asthma, and urticaria were common symptoms.

  • SPT showed 74% concordance with case history; RAST showed 77% concordance with SPT.
  • Significant cross-reactivity observed within Compositae and Amaryllidaceae families.

    • Conclusions:

    • Homemade flower extracts are effective for diagnosing IgE-mediated flower allergy.
    • Mugwort can serve as a screening test for potential flower allergies.
    • Flower allergies frequently necessitate profession changes for affected individuals.
