A new study has found the addition of long-acting beta-agonist therapy to be the most effective of three step-up, or supplemental, treatments for children whose asthma is not well controlled on low doses of inhaled corticosteroids alone.
The study was designed to provide needed evidence for selecting step-up care for such children and was supported by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. Researchers also identified patient characteristics, such as race, that can help predict which step-up therapy is more likely to be the most effective for a child with persistent asthma.
The study found that almost all of its participants had a different response to the three different treatments. Although adding the long acting beta-agonist step-up was one and one-half times more likely to be the best treatment for most of the study group, many children responded best to other two treatments instead.
The results were presented March 2 at the American Academy of Asthma, Allergy and Immunology 2010 Annual Meeting in New Orleans and are published online in the New England Journal of Medicine.
