Mite-Proof Bedding May Help Curb Asthma Attacks
By Robert Preidt
Children with asthma have fewer flare-ups when their beds have mite-proof covers, a new study suggests.
Dust mites are one of the most common asthma triggers.
The study included 284 children in England with asthma and dust mite allergy. Their mattresses and pillows were encased with mite-proof or placebo covers. They were tracked for a year.
During that time, about 29 percent of the kids with mite-proof covers had a severe flare-up that led to a hospital visit, compared to about 42 percent of the other kids.
Children with protective bedding also went much longer before having a flare-up that led to an emergency room visit or hospital stay for treatment with systemic corticosteroids.
But they did not have a significantly lower risk of flare-ups that were treated outside the hospital with only an oral corticosteroid. The researchers said the bedcovers may not prevent flare-ups but instead make them less severe.
The study, published online March 10 in the American Journal of Respiratory and Critical Care Medicine, was funded by The JP Moulton Charitable Foundation.
