Abstract

While bronchoalveolar lavage is frequently performed to evaluate immunocompromised hosts for infection, the significance of rare yeasts found on the cytologic examination of lavage fluid is unclear. This study used the latex agglutination method to test lavage fluids for Candida antigen to assess its usefulness in distinguishing Candida pneumonia from Candida colonization of the respiratory tract or oral contamination of the lavage specimen. Ninety-seven specimens from 87 patients were categorized on the basis of historical, microbiologic, cytologic and serologic data. Bronchoalveolar lavage fluids were positive for Candida antigen in 0 of 20 specimens from normal controls, 0 of 14 specimens from patient controls, 5 (36%) of 14 specimens from patients with Pneumocystis carinii pneumonia, 0 of 5 specimens from patients with gastrointestinal candidiasis, 0 of 9 specimens contaminated by oral-derived yeasts, 2 (10%) of 19 specimens from patients with probable Candida colonization and 15 (94%) of 16 specimens from patients with clinical and laboratory evidence of Candida pneumonia. We conclude that this test assists in the differentiation of Candida pneumonia from other situations in which yeasts are recovered by bronchoalveolar lavage.
