Impact of Reduction of Dust Mite Allergenic Load on Step Down of Inhaled Corticosteroids in Stable Asthma

Eviction methods for dust mite allergy have been evaluated in asthma control in a recent Cochrane meta-analysis. None have shown efficacy on asthma control and there are not recommended. The purpose is to evaluate the efficacy of a new commercialized system (Acar'Up) to decrease dust mite load and to assess its impact on the possibility to perform inhaled corticosteroids step down in stable asthmatics.

Detailed Description

Eviction methods for dust mite allergy have been evaluated in asthma control in a recent Cochrane meta-analysis. None have shown efficacy on asthma control and there are not recommended. The purpose is to evaluate the efficacy of a new commercialized system, Acar'Up (a spray pulverized on a technical textile that traps the dust mite) to decrease dust mite load and to assess its impact on the possibility to perform inhaled corticosteroids step down in stable asthmatics.
