Abstract:
Storage mites are believed one of the most important allergens in farmers and rural regions. Tyrophagus putrescentiae, belonging to storage mites, is found not only within storehouses but also in the house dust, and the third most common mites following Dermatophagoides farinae and Dermatophagoides pteronyssinus in house dust in Korea. The sensitization rate to Tyrophagus putrescentiae was reported as high as that of house dust mite in patients visiting the allergy clinic in large cities in Korea. We experienced a 69-year-old man who had suffered from dyspnea, wheezing, and coughing for 10 years. He retired from the teaching profession, and had lived in a large city, Deajeon. The skin prick test showed a positive reaction to Tyrophagus putrescentiae and negative reactions to house dust mites. The bronchial challenge test with Tyrophagus putrescentiae showed late asthmatic reaction. We confirmed a Tyrophagus putrescentiae-induced asthma in non occupational setting.
