INTRODUCTION. The objectives of this research were to identify some characteristics and risk factors in children with recurrent wheezes 10 years after the first episode of acute bronchiolitis caused by respiratory syncytial virus. METHODS. A descriptive retrospective longitudinal study was conducted among 34 children that were classified as transient wheezing and persistent wheezing. Risk, socioeconomic and environmental factors were identified. Skin sensitive tests with aeroallergens were performed. RESULTS. Persistent wheezes were observed in 22 patients (64.7 %) and transient wheezes in 12 (35.3 %). The most common atopic family history was bronchial asthma with predominance in children with persistent wheezes (68.1 %). Early weaning was the most frequent personal history. Smoking and the attendance to day care centers were the prevailing socioeconomic and environmental risk factors (63.6 % and 59 %, respectively), specially in children with persistent wheezes. Six persistent wheezing children (27.2 %) required attention at the Polivalent Intensive Care Unit, whereas only one transient wheezing child (8.3 %) had to be admitted in that unit. The aeroallergen skin-prick tests yielded positive in 7 permanent wheezing children (31.8 %) and in 1 transient wheezing child (8.3 %). CONCLUSIONS. The recurrent wheezes in the child after a first episode of bronchiolitis due to respiratory syncytial virus are generally associated with risk factors, particularly to the atopic family history and smoking. It is very important to early identify the children at risk for presenting atopic persistent asthma and to take therapeutic measures in order to prevent the deterioration of the pulmonary function.
