  • Diagnostic Fiberoptic Bronchoscopy and Protected Brush Culture: RESULTS part 2

Bronchoscopy Before Start of Antibiotic Therapy

A presumptive etiologic diagnosis, valuable for the management of the patients, was obtained in all of the six patients examined before the start of antibiotic therapy (Table 4). The PB culture was positive in four of the patients, whereas in one patient (No. 21), S pneumoniae was found only in cultures from bron­chial secretion. In the last patient (No. 24), a bronchial tumor was found, but no infectious agent.

Versatility of Bronchoscopy

Examination with the PB catheter was used in 23 of 24 patients. Among these 23 patients, seven had true positive findings, six positive cultures and one pneumococcal antigen. No false positive findings were demonstrated, which corresponds to a positive predic­tive value for the PB of 100 percent. eriacta 100 mg

Of the 16 negative PB findings, only three were considered as possibly false, which corresponds to a negative predictive value of ^81 percent.

Altogether, the result of the bronchoscopy was considered valuable for the management in 19 of 24 (79 percent) patients, 12 with positive and seven with negative findings (see definitions).
