Additional diagnostic analyses of the BAL fluid have included adenosine deaminase level and enzyme-linked immunosorbent assay for antibodies to M tuberculosis. Extension of pulmonary tuberculosis after FOB occurs rarely. During the procedure, precautions must be taken to prevent transmission to the bronchoscopy staff. buy flovent inhaler
Atypical Bacterial Pneumonia Mycoplasma pneumoniae
Mycoplasma pneumoniae is a procaryote lacking a cell wall that causes 11 to 17 percent of the CAP occurring in patients older than 40 years. Although usually benign and self-limited, severe complications can occasionally occur. M pneumoniae may be readily detected from throat or sputum specimens. Two investigators, however, have reported on the use of BAL to diagnose M pneumoniae. Lehtomald et al subjected to bronchoscopy with BAL and PSB nine previously healthy conscripts with acute pneumonia. Mycoplasma was cultured from the BAL fluid after 6 to 17 days of incubation in 6 patients, all of them with serologic evidence of infection. Farides et al investigated the frequency of isolation of Mycoplasma in the BAL of immunosuppressed patients presenting with diffuse infiltrates. In three (5 percent) of 61 patients, M pneumoniae represented the only organism identified despite a thorough search for other causes. In the above two studies, sputum or throat specimens were not obtained for comparison.
