Purpose : Okinawa Prefecture has a specific IgE antibody possession status that differs from that of the rest of Japan, so we investigated the changes in this status over the last 10 years. Subjects and methods : Specific IgE antibody test results for house dust mites (mites), house dust 1 (HD), cat dander, dog dander, cedar, Candida, and Aspergillus were analyzed. Results : We analyzed 269 cases with nasal symptoms. The highest positive rates were observed in those with allergic rhinitis. The rate of positivity for at least 1 item was 91.5% in cases of allergic rhinitis, followed by 45.5% in those with eosinophil sinusitis/allergic fungal sinusitis. Regarding those with nasal allergies, 88.2%, 83.2% and 30.2% were positive for mites, HD and cat dander, respectively, which was higher than that in the rest of Japan. In contrast, the rate of positivity for cedar was 8.4%, for dactylis was 6.1% and for ragweed was 3.1%. The multiple antigen-positive rate for nasal allergy was low, and the larger the mite class, the higher the multiple antigen-positive rate. Conclusion : The sensitization rate of mites and house dust is increasing, and guidance on the living environment is essential. In addition, the prevalence of antibodies against cat dander is rising, making it necessary to pay close attention to future trends. Okinawa Prefecture is the best place for health tourism against pollinosis.
