Review Comparative StudyComparative effect of body mass index on response to asthma controller therapy.
Increases in body mass index (BMI) are reported to influence asthma severity and response to treatment. This analysis was designed to explore whether increasing BMI altered the comparative response to treatment with either fluticasone propionate (FP) or montelukast. Two double-blind, randomized, parallel-group trials of 12-weeks duration comparing FP, 88 micrograms, twice daily or montelukast, 10 mg, daily were evaluated. ⋯ FP was statistically superior to montelukast for all BMI categories of normal, overweight, and obese subjects for FEV(1) (p < 0.008), morning peak flow (p < 0.002), albuterol use (p < 0.02), and symptom scores (p < 0.05). FP produced a significantly greater clinical response for normal, overweight, and obese subjects compared with montelukast. Irrespective of BMI, FP appears to be the more effective asthma controller therapy.
