Abstract

House dust from high mountainous areas of Switzerland contains very few house-dust mites. In contrast to lower-lying regions, only very small quantities of house-dust allergen are found at high altitudes.The cause of this phenomenon seems likely to be the climatic conditions in the high mountains of Europe, where cold air leads to extremely low humidity levels indoors. The soil conditions and a type of construction providing good protection against the penetration of water also contribute to dry conditions in houses. These factors prevent the development of large populations of allergen-producing house-dust mites.The beneficial effect of a stay at high altitudes on patients with atopic asthma is probably due to the low concentrations of house-dust allergen.

摘要

瑞士高山地区的室内灰尘中尘螨数量极少。与地势较低的地区相比,高海拔地区仅能检测到极少量的室内灰尘过敏原。造成这种现象的原因可能是欧洲高山地区的气候条件,冷空气导致室内湿度极低。土壤条件以及一种能有效防止水渗透的建筑类型也使得房屋内较为干燥。这些因素阻碍了产生过敏原的室内尘螨大量繁殖。高海拔地区对特应性哮喘患者有益,可能是由于室内灰尘过敏原浓度较低。
