This case report details a mouse dander-allergic bronchial asthma diagnosis in a pharmacy professor. The study identified a 21 kDa allergenic molecule responsible for the severe respiratory symptoms.

Area of Science:

  • Allergy and Immunology
  • Respiratory Medicine
  • Occupational Health

Background:

  • Occupational exposure to animal allergens can trigger respiratory conditions.
  • Asthma can develop or be exacerbated by environmental triggers, even after prolonged exposure.
  • Identifying specific allergens is crucial for managing allergic diseases.

Observation:

  • A 47-year-old female pharmacy professor developed severe asthma symptoms including dyspnea and wheezing upon recent contact with mice.
  • Symptoms occurred despite years of prior uneventful animal experimentation.
  • Symptomatic relief was achieved by removing the allergen or using bronchodilators.

Findings:

  • A causal link between mouse dander exposure and bronchial asthma was confirmed.

  • Diagnostic tests including skin prick testing, RAST, and bronchial provocation were positive.
  • SDS-PAGE and immunoblotting identified a 21 kDa protein as the specific mouse allergen.

    • Implications:

    • Highlights the potential for developing allergies to animal dander, even after long-term exposure.
    • Emphasizes the importance of allergen identification in occupational asthma.
    • Informs strategies for prevention and management of allergic respiratory diseases in laboratory settings.
