Abstract | Molecular epidemiology studies on cryptococcemia are limited. This study aimed to describe the clinical features of patients with bloodstream infections by Cryptococcus sp. in a public tertiary hospital in Mato Grosso do Sul, as well as identify the fungus’ molecular type and determine its antifungal susceptibility. Molecular typing was performed using URA5 restriction fragment length polymorphism PCR, and antifungal susceptibility was determined by microdilution method standardized by the Clinical and Laboratory Standards Institute. Over 14 years, 48 patients were diagnosed with cryptococcemia. The majority (72.9 %) was male with a median age of
40 years; 81.3 % of the patients had HIV/AIDS and 72.9 % died. Cryptococcus neoformans was the most commonly isolated species (97.9 %). Molecular analysis identified the genotypes C. neoformans VNI (93.7 %), C. neoformans VNII (4.2 %), and Cryptococcus gattii VGII (2.1 %). In vitro, these fungi were not resistant to fluconazole, itraconazole, voriconazole, and amphotericin B. This is the first description of the molecular types of cryptococcemia agents in central-west Brazil. Its high lethality, especially in HIV-negative patients, suggests that early diagnosis and prompt antifungal therapy are crucial for a good clinical outcome. | pt_BR |
