Diagnosis of Pulmonary Disease in Acquired Immune Deficiency Syndrome (AIDS)

Abstract

The effectiveness of fiberoptic bronchoscopy with the addition of bronchoalveolar lavage (BAL) was evaluated in 72 patients with the acquired immune deficiency syndrome (AIDS) and parenchymal pulmonary disease. The diagnostic yield varied for different pathogens and was 94% (45/48 cases) for Pneumocystis carinii, 67% (14/21 cases) for cytomegalovirus, and 62% (8/13 cases) for Mycobacterium avium intracellulars Of the 11 cases of documented Kaposi's sarcoma in the lung parenchyma, none were diagnosed from bronochoscopy, although characteristic endobronchial lesions were seen in 6 cases. Overall, the yield of bronchoscopy for all pathogens was 65%. Both transbronchial biopsy and BAL had high independent yields (88 and 85%, respectively) for diagnosing P. carinii pneumonia but combining the procedures gave the best yield. Cytomegalovirus was most often diagnosed from examination and culture of the BAL. Recovery of Mycobacterium avium intracellulare was highest with culture of both washings and lavage. Neithe...
