Lack of utility of bronchial brush biopsy in patients infected with the human immunodeficiency virus.
While bronchoalveolar lavage has been shown to be more sensitive than brush biopsy (BB) for the diagnosis of Pneumocystis carinii pneumonia in AIDS patients, some have reported that BB occasionally is positive in spite of a negative BAL. Many bronchoscopists, therefore, continue to perform routine BB when doing bronchoscopy on AIDS patients. We performed a retrospective study of all fiberoptic bronchoscopies done on human immunodeficiency virus-infected patients over a one-year period at our institution to determine if the use of BB added to the diagnostic yield of bronchoscopy over that of BAL alone. Of 84 bronchoscopies in which BB was performed in addition to BAL, BB yielded no diagnoses that were not obtained by BAL. Brush biopsy added approximately $400 to the cost of bronchoscopy. We conclude that BB should not be routinely done when performing bronchoscopy on HIV-infected patients.
