Invasive Fungal Infection in Romania: Changing Incidence and EpidemiologyDuring SixYears of Surveillance in a Tertiary Hospital

摘要

The present study aimed to evaluate the incidence of candidemia, the trend of species distribution and the antifungal susceptibility patterns of all invasive strains of Candida spp. isolated over a 6-year period in an Eastern European University hospital. A total number of 156 isolates were reidentified by MALDI-TOF and tested for susceptibility by Sensititre(TM) YeastOne. Isolates were assigned as non-susceptible or belonging to the wild type according to the new CLSI (2017, 2018) break points and epidemiological cut-off values. C. parapsilosis (37.82%) was the most frequently isolated yeast, followed by C. albicans (26.28%). The general tendency of the species distribution during the surveyed period shifted towards an increase in C. parapsilosis and C. lusitaniae isolates. Fluconazole resistance was present in 23.52% of C. glabrata, 5.08% of C. parapsilosis and in none of the C. albicans, C. tropicalis and C. lusitaniae isolates. Echinocandin resistance was present only in 1(5.88%) C. glabrata isolate. The study emphasises the importance of monitoring local epidemiologic data and antifungal susceptibility trends due to the diversity of affected patient groups in our hospital.
