Pulmonary infections, including mixed infections, are common in patients
with human immunodeficiency virus (HIV), and a specific diagnosis is
desirable to direct therapy. In a retrospective study of patients
suspected of having Pneumocystis carinii pneumonia, we examined the
usefulness of fiberoptic bronchoscopy in the immediate diagnosis of
tuberculosis. In 267 patients, pneumocystis pneumonia was diagnosed in
115 (43%), of whom 5 (4%) also had concomitant tuberculosis.
Bronchoalveolar lavage gave an immediate diagnosis of tuberculosis by
positive acid-fast bacilli stain in 3 patients, while the transbronchial
biopsy was suggestive in a fourth. Four of these patients developed
respiratory failure, and 2 died. In patients with pneumocystis
pneumonia, respiratory failure was significantly more common in those
with tuberculosis (P = .0077). In 156 (58%) of the 267 cases,
bronchoalveolar lavage was negative for pneumocystis pneumonia, while
tuberculosis was diagnosed in 14 (9%), and an immediate diagnosis was
made in 10 (71%). In a series of HIV-infected patients suspected mainly
of having pneumocystis pneumonia, tuberculosis was found instead in 19
(7%), and both diseases were present in 5 (2%). Bronchoscopy provided an
early diagnosis of tuberculosis in 63%. Patients with concomitant
pneumocystis pneumonia and tuberculosis had a high rate of respiratory
failure.
