Plastic bronchitis associated with adenovirus serotype 7 in children

Abstract

Abstract Background Plastic bronchitis is an uncommon but severe respiratory disease characterized by formation of casts in tracheobronchial tree. It can lead to airway obstruction and even respiratory failure. Case presentation Plastic bronchitis is mostly seen in both post-cardiac surgery patients, especially Fontan procedure, and infections including those caused by influenza viruses, Mycoplasma pneumoniae or tuberculosis. But it has rarely been reported to be associated with adenovirus infection. We report 2 cases of plastic bronchitis arising from adenovirus serotype 7 infection, manifested in repeated high fever, cough, and progressive dyspnea, and were diagnosed and eventually cured by bronchoscopy. Conclusions Plastic bronchitis is a rare, variable and potentially fatal disease. In the cases we described, the cause was associated with adenovirus serotype 7 and its treatment required intervention with bronchoscopy and adequate control of the underlying disease.
