Why Does Airway Inflammation Persist? Is It Failure to Treat Early?

At present there is no direct evidence to demonstrate that early use of antiinflammatory therapy will reduce the persistence of airway inflammation. However, there is evidence that early treatment with inhaled corticosteroids is associated with better clinical effects, including a modification of the course of asthma so that it becomes easier to treat. Exactly how or if this relates to differences in control of airway inflammation is not known.
