Abstract

Bronchiectasis (BE) are abnormal bronchial dilatations and a paediatric chronic lung disease important cause. They can be congenital or mostly secondary to other pathological entities. In developing countries as Chile, the leading cause is post-viral pneumonia (PN) and among these, Adenovirus (ADV) is the most important cause.
Aiming to assess the magnitude of this problem in our paediatric population, a descriptive retrospective study was made. Using the Hospital statistics, we selected all the patients with BE diagnosis confirmed by computerized tomography (CT), secondary to ADV PN confirmed by Indirect Immunofluorescence, who were under control in our Unit between January 2001 and January 2002 (N=24). An analysis of their clinical records was made.
We found 16 males and 8 females. The ADV PN occurred at a mean age of 304 days. BE were diagnosed at a mean age of 5 years, mostly because of lack of money to perform a High Resolution CT earlier. According to localisation, in 13 cases they are bilateral, in 7 the lower left lobe is affected , in 3 the upper right lobe and in 1 the lower right lobe. 6 patients were oxygendependent during their evolution. Spirometry (SP) was performed in 17 patients (6 patients were excluded because of their age and 1 because of her mental status). In only one patient it was normal, 14 had different degree obstructive pattern (8 of them showed no significant changes after bronchodilator) and 2 mild restrictive pattern. No patient underwent surgery.
ADV PN is an important cause of chronic lung disease among our children. BE secondary to ADV PN frequently are bilateral and they show obstructive spirometric pattern. No patient required surgery. We should improve our BE diagnosis.
