title: Bronchoscopy in the human immunodeficiency virus-infected patient.
abstract: The spectrum of pulmonary manifestations in patients infected with human immunodeficiency virus (HIV) is broad, including many infectious and noninfectious complications. In the evaluation of an HIV-infected patient with diffuse pulmonary disease a definitive diagnosis is preferred over empiric therapy in most patients. Patients with focal consolidation usually receive empiric treatment for community-acquired pneumonia, with nonresponders undergoing additional diagnostic testing. Bronchoscopy remains a cornerstone in the diagnostic evaluation. A multilobar bronchoalveolar lavage (BAL) is usually sufficient for the diagnosis of Pneumocystis carinii pneumonia (PCP) and avoids the additional complications of hemorrhage and pneumothorax associated with transbronchial biopsy (TBBX). However, TBBX improves the sensitivity for diagnosis of tuberculosis and fungal pneumonias and is necessary to confirm invasive aspergillosis. Definitive criteria for diagnosis of cytomegalovirus pneumonitis have yet to be established, although bronchoscopic specimens usually are used. Tissue confirmation with TBBX is required for the diagnosis of noninfectious disorders such as non-Hodgkin's lymphoma and lymphocytic and nonspecific pneumonitis. Bronchoscopic visualization of typical lesions often is sufficient for the presumptive diagnosis of Kaposi's sarcoma (KS) although the diagnostic yield is enhanced by the detection of human herpes virus 8 in BAL samples.
