Micro-organism counts of bronchoalveolar lavage (BAL) and microbrush swabs were obtained from 40 immunocompetent (group A) and 23 immunosuppressed (group B) patients with nosocomial pneumonia, and a control group consisting of 40 patients with noninfectious pulmonary infiltrates. The sensitivity of BAL was high: 77.5% for group A and 85% for group B, while microbrush swabs gave many false-negative results. Microorganism counts were at or above 10(5) cfu/ml in 32 of 44 examinations (bacterial or mycotic pneumonia), but in only one case of the control group. Lower counts were obtained with localized infection and microorganisms difficult to culture (Aspergilla and Legionella). Granulocytosis in the lavage fluid was demonstrated in 38 of 41 patients with bacterial pneumonia and thus proved useful in the differential diagnosis. In 16 of 40 immunocompetent and 13 of 23 immunosuppressed patients with pneumonia the results were therapeutically of importance. Thus, invasive diagnosis is indicated especially in complicated or treatment-resistant nosocomial infections.
