[From bronchiolitis to asthma].
Relationships between lower respiratory diseases with wheezing during infancy and asthma at school-age remain debatted. Indeed, although epidemiologic studies show that wheezy infants most often become asymptomatic before entry to school, they also demonstrate that severe bronchiolitis during infancy is a significant risk factor for persistence of wheezing episodes at school-age. One of the most important factors demonstrated to enhance the risk for persistence of asthma is an early allergic sensitization.
