[Short-term outcome of infants hospitalized for an attack of acute bronchiolitis].

The authors report the clinical, biological, radiological findings of 109 infants hospitalised for acute bronchiolitis. A prospective study was possible in 74 of them with an average of follow up of 18 months. After the admission, 31% were asymptomatic, 56% suffered at least one or several episode of wheezing, 13% have recurrent or chronic bronchopulmonary symptoms including cough and airway obstruction. Three points appeared determinant to predict recurrent wheezing: the rate of IgE, a familial history of atopy, and radiological pulmonary hyperexpansion. There was no statistic difference of evolution between the infants with wheezing at the admission and the others. The main prospective studies were analysed for discussion of the prognostic problems.
