| dc.description.abstract | OBJECTIVE: Recent research has suggested that fungemia may demonstrate an epidemiologic shift in etiologic agents. This study focuses on the agents causing fungemia and antifungal resistance in a tertiary hospital.
PATIENTS AND METHODS: We evaluated all-age fungemia cases admitted to Balikesir Ataturk City Hospital in 2017-2021. Blood cultures (BC) were studied using BacT/Alert (R) 3D (bioMerieux, Marcyl'Etoile, France) and Render BC128 System (Render Biotech Co. Ltd., Shenzhen, China). On the data, we explored only the first fungal positive samples or the first isolates in different episodes of the same patients. Upon The Clinical and Laboratory Standards Institute (CLSI) disk diffusion guidelines, conventional methods and the Phoenix (TM) 100 System (Becton Dickinson, Franklin Lakes, NJ, USA) were utilized for antifungal susceptibility identifications.
RESULTS: The findings showed that 325 (0.84%) of 38,682 BC sets were positive for fungal growth. Except for four cases (1.2%) [Saprochaete capitata (n = 2); Trichosporon asahii (n = 1), and Saccharomyces cerevisiae (n = 1)], all positive cases yielded Candida spp. (98.8%) growth. In these patients, the following Candida spp. were isolated: Candida albicans complex (n = 155; 47.7%), Candida parapsilosis complex (n = 127; 39.1%), Candida glabrata c omplex (n = 19; 5.85%), Candida tropicalis (n = 12; 3.7%), Candida kefyr (n = 5; 1.54%), Candida krusei (n = 2; 0.62%), and Candida guilliermondii complex (n = 1; 0.31%). We also realized that while none of the Candida spp. had echinocandin resistance, 8 C. parapsilosis complex isolates were resistant to fluconazole, and 17 C. parapsilosis complex and 2 C. tropicalis isolates were susceptible dose-dependent to fluconazole.
CONCLUSIONS: In brief, antifungal resistance is more likely to restrict therapeutic options, albeit it is, fortunately, not prevalent in Turkey despite a few recent reports. Yet, a robust detection or management of antifungal resistance requires species-level identification and strict compliance with relevant management guidelines. Besides, challenges in research may be compensated with a national data set built with data from local laboratories. | en_US |
