Chronic and recurrent @entity11127 are a frequent problem in general practice. The purpose of the study was to investigate the role of @entity56 to house dust mites in @entity11127 in general practice @entity1 . We tried to assess the influence of determined risk factors exposure on development of respiratory tract @entity566 . @entity1 from family practitioners surgeries with chronic or recurrent respiratory tract symptoms who had no diagnosis of @entity566 were recruited to the study (n = 89). All @entity1 responded to a questionnaire focused on history of symptoms, @entity558 in family and exposure to determined environmental factors like dwelling conditions, obstetrician history, diet in the first year of life. All @entity1 underwent skin prick test with common inhalant allergens. Families of the @entity1 were asked to participate in the study. Families who agreed to take part also responded to the questionnaire and underwent skin tests. In @entity1 and their families blood samples were taken to determine total IgE and specific IgE antibodies to mites allergens. Dust samples were collected by vacuuming of @entity1 ' bedroom carpets and mattresses to determine house dust mites allergens concentration. Data on 30 complete @entity1 family sets of their brotherhood, mother and father were collected. Total and specific serum IgE antibodies were determined by disc enzyme-immunoassay (Analco). Mites allergens concentration in dust was measured by simple Acarex strip test (Nexter). The results of the assays (positive skin tests and/or elevated levels of specific IgE) showed @entity566 to house dust mites in 24 of 89 study @entity1 from general practitioners surgeries (27%). The prevalence of @entity2490 , recurrent @entity3617 , chronic or recurrent cough, wheezing, dyspnoea was higher in allergic than in nonallergic subjects. @entity1 with the diagnosis of @entity566 to house dust mites had usually worse dwelling conditions. Especially the influence of dampness in flats on several respiratory symptoms was observed. Subjects who had been found to be allergic were more frequently exposed to higher concentrations of house dust mites allergens in bedroom carpets and in mattresses. In allergic @entity1 early introducing of sensitizing components into the diet in infancy related to shorter breast feeding was observed.
