ITS1/ITS2 polymerase chain reaction sequencing was significantly better at identifying fungal chronic rhinosinusitis (CRS) than were cultures, according to Dr. Pauline Comacle and her associates.
A total of 70 samples from 61 patients with CRS were tested via the use of polymerase chain reaction (PCR) testing and cultures. Fungal CRS was identified in 42 patients, of whom 37 had a fungus ball, 3 had allergic fungal CRS, and 2 had unspecified fungal CRS. ITS1/ITS2 PCR sequencing successfully identified fungal CRS in all patients, while cultures were positive for fungal CRS in 20 of the 42 patients.
Aspergillus fumigatus was the most common fungus in the study, occurring in 69% of patients. Cladosporium cladosporoides occurred in 9.5% of patients, and A. nidulans, A. flavus, and Scedosporium species each occurred in 7% of patients.
“This study nicely shows that molecular methods are powerful tools for the diagnosis of chronic rhinosinusitis and help in characterizing the accurate epidemiology of fungal CRS,” the investigators concluded.
