Prolonged exposure to @entity6711 ( @entity6711 ) of the Pyroglyphidae family leads to the development of @entity9590 ( @entity9590 ) in sensitized subjects. In @entity9590 @entity1 @entity6587 --the clinical manifestation of @entity32 in the lower airways is often observed. The aim of the study was to estimate the influence of the exposure to @entity6711 in @entity9590 @entity1 on selected functional parameters of the lower airways. The study was performed on 64 @entity1 with @entity9590 caused by @entity566 to @entity6711 ( @entity7130 , @entity8786 ) without either symptoms of @entity565 or @entity854 . The lower airways function was estimated by bronchial @entity112 provocation test (BHR) and flow-volume spirometry. The house dust mite quantity was measured in dust samples collected in spring and autumn. One sample was assessed by flotation technique with the use of @entity1044 and the mites species were identified (direct method) and the other sample was used to perform the Acarex test (semiquantitative guanine determination test). Positive result of Acarex test was obtained in spring in 72% houses and in autumn in 63%. The predominance of the Pyroglyphidae family was observed in @entity9590 @entity1 ' houses. The study showed that the exposure to the allergenic @entity6711 in the quantity higher than 0.6 mg @entity2774 /g dust in autumn implies the increased incidence of both @entity6587 and decreased airflow in the small bronchi in control spirometry tests. A strict correlation between the quantity of mites in houses in spring and autumn measured by the direct (flotation method) and the indirect (Acarex) tests was observed. Both methods proved to be equivalent in detecting allergens of @entity6711 .
