Children with asthma who continue to have symptoms while using low-dose inhaled corticosteroids could benefit from increasing the dosage or adding one of two asthma drugs, a new study by researchers at Washington University School of Medicine and other institutions finds.
Results of the study, called BADGER (Best ADd-on therapy Giving Effective Responses) may also allow physicians to better predict which of the three options will help a patient the most.
To treat children whose asthma is not well controlled while using low-dose inhaled corticosteroids, the National Heart, Lung, and Blood Institute (NHLBI) guides physicians to try one of three additional, or step-up, treatments: doubling the dosage of the inhaled corticosteroid or adding a long-acting beta antagonist (LABA) or a leukotriene receptor antagonist (LTRA) to the inhaled corticosteroid treatment.
However, physicians often find it difficult to predict which step-up treatment might work best for a particular child. So the researchers in the five-center, NHLBI-funded Childhood Asthma Research and Education (CARE) Network used a novel triple-crossover, double-blind approach to determine if the treatments improved asthma symptoms, and if so, which treatment might work best.
Robert C. Strunk, M.D., and Leonard B. Bacharier, M.D., both Washington University pediatric asthma specialists at St. Louis Children's Hospital, were coauthors on the study, published online March 2, 2010, by the
New England Journal of Medicine and presented the same day at the American Academy of Allergy, Asthma and Immunology's annual meeting in New Orleans.
