Background: The prevalence of allergic diseases such as allergic rhinitis, asthma, and atopic dermatitis were increased worldwide including Thailand. The aeroallergen sensitization plays a critical role as a major risk factor for developing allergic diseases. There are vary in the prevalence of common aeroallergens sensitization depend on the geography and altitude.
Objective: To demonstrate the prevalence of common aeroallergens sensitization by skin prick test in adult allergy clinic at Ramathibodi Hospital.
Methods: This is a retrospective study collected data from database of adult allergy clinic and medical records of participants who experienced rhinitis and/or chronic urticaria and visited adult allergy clinic at Ramathibodi Hospital during January 2004 to December 2015. All of participants was done skin prick test to aeroallergens.
Results: Of 1,516 patients enrolled with allergic diseases, 1,118 patients (73.7%) were female, . the mean age was 41.34 ± 16.5 years. The patients had allergic rhinitis (58%), asthma (19.7%), atopic dermatitis (3.2%), and chronic urticaria (9.2%). All of patients were done the skin prick test to 17 aeroallergen commercial extracts. The result of skin prick test illustrated that mites (64.8%) was the most common aeroallergen sensitization in adult patients, followed by grass pollen (36%), cockroach (32.3%), house dust (31.5%), cat dander (12.9%), and dog dander (10%), respectively.
Conclusion: Mites is the major aeroallergen sensitization followed by grass pollen, cockroach, house dust, and animal dander.
