Inhaled steroids don't work for some asthma patients

There is a new finding about genes and asthma that may explain why some 40 percent of people with asthma do not respond well to inhaled steroids.

Asthma patients who inherited two copies of a specific gene variant were far less likely to do well with this treatment.

This advances the possibility that doctors could do a test to figure out who will respond to inhaled corticosteroids and who won't.

Inhaled steroids work by reducing swelling of the airways.

Details of the study were released online in the New England Journal of Medicine.
