Pet dander allergy is common in asthma and rhinitis patients. Living with pets significantly increases the risk of skin hypersensitivity to cat and dog allergens.

Area of Science:

  • Allergy and Immunology
  • Environmental Health

Background:

  • Asthma and rhinitis are common conditions often exacerbated by environmental allergens.
  • Exposure to domestic animals like cats and dogs is a potential risk factor for allergic sensitization.

Purpose of the Study:

  • To determine the incidence of skin test positivity to cat and dog danders in symptomatic outpatients.
  • To investigate the association between home animal exposure and allergic sensitization.

Main Methods:

  • A cohort of 802 symptomatic outpatients with asthma and rhinitis were studied.
  • Skin prick tests for cat and dog danders were performed.
  • A standard questionnaire assessed home exposure to pets.

Main Results:

  • 14.3% of all patients tested positive to cat and/or dog danders.
  • Patients living with pets had a significantly higher incidence of hypersensitivity (25%) compared to those without pets (10.4%).
  • Subjects owning both cats and dogs showed a higher incidence of hypersensitivity.

    • Conclusions:

    • Home exposure to cats and dogs is associated with a significantly higher incidence of allergic sensitization.
    • The study did not find a difference in sensitivity between cat and dog danders or increased sensitization to dust mites.
    • No difference in clinical manifestations (asthma, rhinitis) was observed between pet owners and non-pet owners.
