| Description | We evaluated the performance of a galactomannan (GM) assay in bronchoalveolar lavage (BAL) fluid compared to serum samples for the diagnosis of invasive pulmonary aspergillosis (IPA) in patients with hematological diseases. Results: Twenty-eight cases of IPA (11%) were diagnosed. The highest sensitivity (78.6%) with good specificity (98.6%) was obtained with a triple detection of GM in bronchial, alveolar, and serum samples. Neutropenia and antifungal therapy for only 24 h increased the sensitivity, while antifungal treatment for more than 2 days decreased assay performance.Conclusions: In contrast to recently published data, we found only moderate sensitivity, but high specificity and high positive predictive value of the detection of GM in BAL fluid. |
