title: Fiberoptic bronchoscopy for diagnosis of opportunistic pulmonary infections after bone marrow transplantation.
abstract: As a part of the diagnostic procedure for 16 suspected pulmonary infections in 15 marrow transplant recipients fiberoptic bronchoscopy with bronchoalveolar lavage (BAL), transbronchial lung biopsy (TBB) and brushing were performed. Cytomegalovirus (CMV) was the most common microorganism and CMV pneumonia was diagnosed in 8/16 (50%) episodes of pulmonary disease studied. Pneumonias were diagnosed as caused by Candida or Aspergillus species in 6 episodes and by gram-positive cocci in 2 cases. Adenovirus and Pneumocystis carinii was also isolated in 1 patient each. Three noninfectious diseases (pulmonary oedema, idiopathic pneumonia and pulmonary embolism) were diagnosed by methods other than bronchoscopy. The use of fiberoptic bronchoscopy with BAL and TBB allowed correct identification of 14/18 microorganisms involved. Brushing was less useful. Four patients' pneumonias had a multiple etiology. The bronchoscopy methods used were well tolerated even by patients whose condition was poor.
