[House dust mites and storage compartment mites as allergy inducers].
Perennial respiratory diseases like chronic rhinopathy or bronchial asthma can often be related to an allergy to indoor allergens. Of these, the most relevant allergens are derived from house dust mites. Epidemiologic data show that 8.9% of the general population exhibit a sensitization to house dust mites. Based on a better knowledge of the biology and the living habits of house dust mites effective allergen avoidance measures can be performed which are, however, quite cumbersome and go beyond just encasing mattresses. Of particular relevance is the reduction of the relative humidity below 50%. Relatives of house dust mites are storage mites which are increasingly realized as an important cause of respiratory allergies. The most important is Lepidoglyphus destructor which is dominant in dust probes from Europe and shows crossreactivity with other storage mites. They are found in barns and grain stores and are thus important causes for occupational respiratory diseases in farmers. The existence of storage mites in house dust is connected with damp housing conditions.
