• Background Inhaled corticosteroids are recommended as first-line therapy for children with mild persistent asthma; however, specific patient characteristics may modify the treatment response. Objective Identify demographic, clinical, and atopic characteristics that may modify the inhaled corticosteroid treatment response among children enrolled in the Tr eating Children to Prevent Ex acerbations of A sthma trial. Methods Children aged 6 to 18 years with mild persistent asthma were randomized to 44 weeks of combined, daily, rescue, or placebo treatment. Daily treatment consisted of 40 μg of beclomethasone twice daily. Rescue treatment consisted of 40 μg of beclomethasone accompanying each symptom-driven albuterol actuation. Combined treatment consisted of both. Outcomes included time to first exacerbation and proportion of asthma control days. Fourteen baseline characteristics were selected for interaction testing on the basis of their clinical relevance. Results Two hundred eighty-eight children were randomized. Seventy-five percent were white, and 55% were male. As measured by time to first exacerbation, 4 characteristics identified children who received greater benefit from treatment: non-Hispanic ethnicity, positive aeroallergen skin test result, serum immunoglobulin E level of 350 K/μL or more, and history of oral corticosteroid use in the year before enrollment. As measured by asthma control days, 4 characteristics identified children who received greater benefit from treatment: male sex, positive aeroallergen skin test result, serum immunoglobulin E level of 350 K/μL or more, and incomplete run-in asthma control. Conclusions Children with mild persistent asthma who have markers of atopic asthma or who have greater asthma burden may obtain greater benefit from beclomethasone therapy. Additional study is needed to confirm whether these markers can guide individualized therapy.
