title: Chronic lung damage caused by adenovirus type 7: a ten-year follow-up study.
abstract: Twenty-seven children aged 0.6 to 7.0 (mean 2.1) years were admitted to the hospital in 1967 and 1968 with type 7 adenoviral pneumonia. All ran a prolonged course. Type 7 adenovirus was isolated from 14 children, and in the other 13, the rise in the titer of complement-fixing antibodies to adenovirus was fourfold or greater. The outcome of the disease in these 27 children was reassessed in 1979, 9.6 to 12.1 (mean 10.7) years after the adenovirus type 7 pneumonia. Twenty-two were examined clinically and roentgenographically and all had lung function tests. Twelve had abnormal chest roentgenograms, and of these, six had bronchiectasis. Six of the ten children with normal chest x-ray films and ten of the 12 with abnormal chest roentgenograms had abnormal pulmonary function tests. Of the six patients with bronchiectasis, four showed no discernible cause of bronchiectasis other than the antecedent type 7 adenoviral infection. The other two patients had bronchial asthma, which can be a risk factor for bronchiectasis.
