[Aspergillus tracheobronchitis in a lung transplant recipient].

Abstract

BACKGROUND:

Aspergillus tracheobronchitis is an uncommon cause of pulmonary aspergillosis and almost exclusively affects lung transplant recipients. There is no lung tissue involvement, thus the tracheobron-chial tree is only affected. Patients are asymptomatic, so it is important to make an early diagnosis to prevent progression of the infection and airway complications. Several prophylaxis and treatment strategies have proven to improve the prognosis.

CLINICAL CASE:

This is the case of a 56 year-old man who underwent bilateral lung transplant for chronic obstructive pulmonary disease (COPD) and developed Aspergillus tracheobronchitis. He received the usual prophylaxis with nebulized liposomal amphotericin B every 48 h. Routine bronchoscopy performed 2 weeks after transplantation showed inflammation with the presence of pseudomembranes that produced a 50% stenosis of the right bronchial anastomosis. Biopsy of the pseudomembranes and bronchial aspirate yielded Aspergillus fumigatus. The patient started treatment with voriconazole twice a day, bronchial debridement through bronchoscopy was carried out, and the treatment with nebulized liposomal amphotericin B was continued every other day. Ten weeks later, there were no endobronchial lesions and the bronchial aspirate cultures were negative.

CONCLUSIONS:

Aspergillus tracheobronchitis is a complication of the lung transplant recipient. Early diagnosis and prompt antifungal therapy, including new antifungal agents and local debridement, may significantly improve the outcome.
