The study, "Eradication of House Dust Mite from Homes of Atopic Asthmatic Subjects", was undertaken by the University of Sheffield in the UK in 1996. The randomized controlled trial sought to determine whether combined steam and heat treatment of home furnishings reduced asthmatic patients' bronchial hyper-reactivity and lowered house dust mite antigen loads in the homes of adults aged 18-45 years.
Trained mite eradication technicians performed the heat-steam-heat treatment on the carpets and upholstery, including mattresses, in the homes of study participants. New pillows were given and bed linens were washed in hot water. Some participants received a positive ventilation system installed in the attic above the bedrooms.
The study has ended, and found a reduction in bronchial hyper-reactivity and a reduction in house dust mite antigen load.
