Asthma Management for the Environment

Researchers analyzed and reviewed recent literature regarding the role of environmental management for asthma prevention and treatment. Although environmental control is a well-established function of asthma therapy, clinical trials do not support its use in primary preventative interventions. Although many of the treatments evaluated in the trials reduced the risk of developing asthma, they often involved diet changes and studies that only addressed environmental exposures were generally negative. The effectiveness of environmental therapies that address asthma triggers, such a laminar airflow device or relocation to high elevation, was demonstrated in patients with asthma. Numerous studies have shown that HEPA purifiers can significantly reduce indoor particulate matter, and improve asthma symptoms. A number of newly published practice standards provided evidence-based recommendations on allergy management for rodents, hairy pets, and cockroaches. Researchers discovered that indoor allergen exposure may be affected by the structure of the dose-response relations and the spatial/temporal characteristics.

Although environmental interventions are unlikely to decrease the chance of developing atopic illnesses, comprehensive treatments can often be helpful in managing asthma, especially in young patients.
