The effect of nebulized budesonide treatment in children with mild to moderate exacerbations of asthma

Abstract

Background: The role of inhaled corticosteroids in the treatment of acute asthma remains a controversial subject.

Objective and methods: A randomized, double-blind, placebo-controlled parallel-group clinical trial on the effect of a 5-d course of nebulized budesonide treatment in children with mild to moderate exacerbation of asthma was performed. The need for systemic corticosteroid intervention was evaluated as the primary outcome measure.

Results: Sixty-seven children aged 6 to 15 y were enrolled. During the emergency department phase, they received three nebulizations of either budesonide(1 mg/dose) or placebo, and then in the home phase of the study, they continued their study medications twice a day for another 4 d. Though the level of improvement in the emergency department phase was similar between the groups given either budesonide or placebo treatments (6.8 +/-1.9% vs 4.0+/-1.5%, p = 0.30, respectively), nebulized budesonide caused a trend towards a benefit in terms of the need for systemic corticosteroid intervention (2/33 vs 7/34, p = 0.07), but not in secondary outcome measures.

Conclusion: Though we show a tendency towards a benefit with nebulized budesonide in children with mild to moderate exacerbations in terms of prevention of progression of the illness, the documented benefit is small and includes, at least, consideration for clinical significance, cost-effectiveness, impracticality and safety.
