Present Conditions of Patients with Nasal Allergies at the Department of Otolaryngology, Kawasaki Medical School—Rates of House Dust Mite and Dematophagoides farinae Allergen-specific IgE Antibody Positivity as Determined Using the CAP-RAST System—

Abstract

The prevalence of allergic rhinitis has been increasing annually. Various allergens can cause allergic rhinitis. House dust mites and Dematophagoides farinae allergen are known to be major causes of allergic rhinitis. This study evaluated the sensitization to house dust mites and D. farinae allergen in 2276 patients who underwent serum-specific IgE antibody evaluations using the CAP-radioallergosorbent test at the Department of Otolaryngology, Kawasaki Medical School, between 2000 and 2014. The tests revealed sensitization to house dust mites in 1082 patients and to D. farinae allergen in 1045 patients. Large fluctuations in sensitization were not observed over the 15-year study period. The house dust mite-specific IgE value was lower than the D. farinae allergen-specific IgE value.
