Research from University of Paris broadens understanding of aspergillosis

"Detection of galactomannan antigen (GMA) in serum is the standard assay for the diagnosis of invasive aspergillosis (IA) in high-risk patients with hematological disorders. Detection of Aspergillus DNA in serum has been proposed, but its sensitivity is lower than that of GMA when small serum volumes (SSV) are used," investigators in Paris, France report. "In this study, we investigated whether extraction of DNA from large serum volumes (LSV) improves diagnostic yield. In a 13-month prospective study, we compared the performances of twice-weekly screening of serum for GMA by an enzyme immunoassay and weekly screening for Aspergillus fumigatus DNA by a real-time PCR...
