PCR for Aspergillus Fumigatus in Blood and Bronchoalveolar Lavage Fluid for Monitoring Cases of Invasive Aspergillosis: What is Its Prognostic Value
Aspergillus fumigatus PCR is currently used in conjunction with serum galactomannan to support the diagnosis of invasive aspergillosis or for monitoring at-risk patients not receiving antifungal prophylaxis. A positive result and a high titer are thought to be associated with the advanced stage of the disease and the fungal load. However, there is limited data on this subject, and no study has primarily focused on the variation of PCR levels during treatment and its potential correlation with treatment efficacy.
• Patients aged 18 years or older
• Positive Aspergillus fumigatus PCR on serum or bronchoalveolar lavage fluid at diagnosis, performed at the Strasbourg University Hospital between January 1, 2017, and December 31, 2024.
