Bronchoscopy with Bronchoalveolar Lavage in Tuberculosis and Fungal Infections
Bronchoscopy with BAL has proved to be a valuable tool in evaluating the inflammatory reaction of the lung in several diseases. In particular, it is useful in assessing the nature of the alveolitis in pulmonary sarcoidosis and hypersensitivity pneumonitis. Both diseases are characterized by a granulomatous reaction in the lung as well as interstitial inflammation. Moreover, both diseases are characterized by an increased percentage of lymphocytes retrieved by BAL, especially in patients with evidence of active, progressive disease. antibiotic levaquin
The study of infectious granulomatous diseases of the lung by BAL is limited. Studies to date have concentrated on bronchoscopy with lavage as a method to diagnose TB. The results to date have been conflicting, and in some cases, recommendations have been made not to use bronchoscopy for diagnosing TB.
Fungal infection represents another infectious granulomatous disease. To date, most reports have centered upon the utility of bronchoscopy and BAL isolating various fungi, especially in immunocompromised patients.
The current study reports the use of bronchoscopy with BAL in infectious granulomatosis. The report deals with the use of bronchoscopy to diagnose infectious agents in patients with fever and obscure diagnosis. In addition, we report the BAL findings in tuberculous and fungal infections.
