TL;DR
This work quantified Der p 1 and Der f 1 and assessed the relationships between their levels and housing characteristics in homes of nonallergic subjects to determine whether these levels may be affected by housing characteristics.
Abstract
BACKGROUND: HDM distribution varies between geographic areas and may be affected by housing characteristics. We quantified Der p 1 and Der f 1 and assessed the relationships between their levels and housing characteristics in homes of nonallergic subjects. METHODS: Der f 1 and Der p 1 were measured by ELISA in dust samples from living-room floors and mattresses of 44 homes of nonallergic subjects in Pavia. Information about household characteristics was obtained by questionnaire. RESULTS: Der p 1 and Der f 1 concentrations (microg/g dust, median) were 0.34 and 7.8 on mattresses, and 0.15 and 0.83 on living-room floors. Higher Der f 1 levels on mattresses were associated with synthetic pillows (P<0.05), and (only when expressed as microg/m2) with bedding washing temperature of < or = 60 degrees C (P<0.05). Der f 1 levels were higher on the living-room floors of homes located on lower (< or =first) floors (P<0.05). Good correlations were found between Der p 1 and Der f 1 expressed as microg/g dust and microg/m2 on both mattresses and living-room floors. CONCLUSIONS: In homes of nonallergic subjects in northern Italy, Der f 1 exceeded the threshold for sensitization in a high proportion of mattress samples.

It is concluded that high concentrations of mite allergen increase the risk of specific sensitization in atopic children and young adults and thus may facilitate allergic airway disease.

The results demonstrate that large seasonal variations in allergen can occur in dust from all sites and are not restricted to the houses of allergic patients, and suggest that mite-allergic patients are more likely to have attacks in the fall at a time when their houses have greater than 10 micrograms AgP1Eq per gram of dust.

Inadequate ventilation appeared to be a risk factor for Hdm sensitization, and this result may apply also to other temperate regions and suggests that the problem is preventable.

The 25 patients with newly diagnosed house-dust mite asthma lived in older and more humid houses than the control subjects did, which explains the greater number of house- dust mites found and suggests possibilities for and the necessity of introducing hygienic standards for the indoor environment as a measure of primary prevention in house-Dust mite allergy.

146 Citations1992Lindy G. McDonald, Euan R. Tovey
Dry cleaning did not reduce the allergen concentration of the dust, although most, if not all, mites were killed, and a cold cycle of laundry washing with or without laundry powder did not remove most live mites from bedding.

Of a total of 14 parameters investigated for their influence on mite numbers, relative humidity was apparently the most important factor, and bedrooms with humidities above 64% contained significantly more mites in mattresses than those with lower humidities.

There is no threshold value for sensitisation to mite allergens in asthmatic children, and therefore, dust allergen levels at home should be kept as low as possible in homes of children at risk for asthma.
