About this trial
The overall objective of the study is to determine the efficacy of corticosteroids in preventing recurrent wheezing and asthma in high-risk, first-time severe wheezing children with rhinovirus infection, stratified by rhinovirus genome load.
The secondary objectives are to determine duration and severity of each acute episode with acute expiratory breathing difficulty, the number of episodes with acute expiratory breathing difficulty, degree of pulmonary hyperreactivity and quality of life within 24 months after study entry.
