BACKGROUND:Exercise-induced bronchoconstriction occurs in a large proportion of children with asthma, limiting everyday activities important for their physical and social development. OBJECTIVE: The purpose of this randomized, double-blind, placebo-controlled study was to compare the ability of different patterns of antiasthmatic treatment, recommended in childhood asthma, to protect patients from exercise-induced bronchoconstriction. METHODS:Children 6 to 18 years of age with atopic asthma were randomized to a 4-week, placebo-controlled, double-blind trial. Patients were randomly allocated to receive daily 200 microg budesonide (twice daily, 100 microg per dose) + 9 microg formoterol (twice daily, 4.5 microg per dose; n = 20); 200 microg budesonide + 5 or 10 mg montelukast (once daily at bedtime; n = 20); 5 or 10 mg montelukast (n = 20); 200 microg budesonide (n = 20); or placebo (n = 20). A standardized treadmill exercise challenge was performed before and after treatment. RESULTS:Exercise-induced bronchoconstriction, reflected by area under the curve for the FEV1 values from exercise over the 20-minute period and by maximum percent fall in FEV1 after exercise, was significantly diminished after 4 weeks in all active treatment groups, and compared with placebo. Exercise-induced bronchoconstriction protection improved more significantly in the budesonide + montelukast and montelukast groups compared with other therapeutic options. CONCLUSION: These data indicate differences in effects on exercise-induced bronchoconstriction between therapeutic options recommended in childhood asthma. Control of childhood asthma with exercise-induced bronchoconstriction can be obtained by using regular controller treatment.
