Sputum induction for diagnosis of Pneumocystis carinii pneumonia.
51 patients infected with the human immunodeficiency virus (HIV) and with suspected Pneumocystis carinii pneumonia underwent sputum induction. Sputum specimens from 18 patients were positive for P carinii and patients were treated appropriately 25 of the 33 patients with negative specimens underwent bronchoscopy and bronchoalveolar lavage within 4 days of sputum induction, only 1 of whom had evidence of Pneumocystis infection. For diagnosis of Pneumocystis carinii pneumonia, sputum induction according to a strict protocol had a sensitivity of 94.7% and a negative predictive value of 96%, compared with bronchoalveolar lavage.
