Abstract:
BACKGROUND: During the past few decades, the prevalence of allergic disorders has increased worldwide. We attempted to reveal the sensitization rate of dust mite allergens, which is one of the most important allergens in Korea, and the prevalence of mite-sensitized asthma in healthy young women who had no history of allergic diseases. METHODS: We performed the skin prick test with two mites (Dermatophagoides farinae, Df; Dermatophagoides pteronnyssinus, Dp) in 24-26 years old 172 women who had no history of allergic diseases. We also performed the methacholine bronchial provocation test (MBPT) and the questionnaire survey of positive skin responders. RESULTS: The 55.2% of subjects showed positive skin responses to house dust mites. The positive rate to MBPT was 54.7% with average PC20 of 15.97+/-7.68 mg/ml and 48.4% had asthma symptoms in the questionnaire survey. Among the methacholine positive population, 6.3% had no asthma symptoms. The history of 3-week cough after upper airway infection was most important, but the most specific item was wheezing. CONCLUSION: The prevalence of dust mite-sensitive bronchial asthma in healthy young women is 26.7%, which is higher than that of previous studies.
