Abstract

The usefulness of galactomannan detection using the Platelia Aspergillus test for the diagnosis of invasive aspergillosis was studied in 849 sera from 54 hematological patients with prolonged neutropenia, which were classified according to the risk for invasive aspergillosis. Three patients developed a proven invasive aspergillosis, one a probable invasive aspergillosis and 17 patients a possible invasive aspergillosis. Thirty-three patients showed no evidence of invasive aspergillosis. All patients with proven invasive aspergillosis had a high risk for invasive aspergillosis, while the one having probable invasive aspergillosis had intermediate risk. Detection of galactomannan in this study showed a sensitivity of 66.7% for patients with proven invasive aspergillosis and 50% for patients with proven and probable invasive aspergillosis. The specificity was 98% or higher in all groups studied. The predictive positive and negative values for patients with proven invasive aspergillosis were 66.7% and 98%, respectively. A rise in the concentration of galactomannan was observed in patients who failed to respond to the antifungal treatment. Galactomannan antigenemia preceded post-mortem histological diagnosis of invasive aspergillosis in two patients by 17 and 81 days, respectively. In conclusion, detection of galactomannan by the Platelia Aspergillus test allows for a specific and relatively sensitive diagnosis of invasive aspergillosis in hematological patients with a high and intermediate risk for invasive aspergillosis.
