title: [From acute viral bronchiolitis in infancy to asthma in childhood].
abstract: Bronchiolitis and wheezy bronchitis are frequently associated with viral infection of the respiratory tract in infants. They play an important role in the natural history of chronic obstructive airway disease, not only in children, but also in adults. The risk of early recurrent wheezing and subsequent asthma or chronic bronchitis (with anatomical sequelae such as obliterans bronchiolitis) is significant. The precise pathogenic mechanisms of virus-induced wheezing and its sequelae are not clear. Whether airway hyperreactivity is inherited and airway hyperreactivity is present prior to, or is the result of bronchiolitis is not clear. Nevertheless the evidence for viral trigger of wheezing and long-term pulmonary sequelae must be considered and prevention must be undertaken at the first episode.
