Sensitization to house-dust mite and mite fauna in selected children's homes in Kütahya, Turkey.
The aim of this study was to determine the relationship between the house-dust mite allergy and prevalence of house-dust mites in dwellings of children who were tested for specific IgE against Dermatophagoides pteronyssinus (D. pteronyssinus) and D. farinae on the suspicion of allergic rhinitis, dermatitis and asthma. All dust specimens collected from children's houses were investigated under a light microscope. House-dust mites were found in 31.7% of houses of children with a specific IgE, while the rate was 27.5% in houses of those without a specific IgE. Overall, house dust specimens collected from a total of 92 houses were examined, and mites were found in 27 (29.3%) of them. Both Der p and Der f were found in 38 (92.7%), while mixed allergy (D. pteronyssinus + D. farinae) was found in 3 (7.3%). Der p allergy (100%) was found in all of the allergic children, while no child was found with specific IgE for Der f allergy, except in mixed allergies.
