Abstract

Objective: To determine the antifungal resistance rate of Candida spp. isolated from patients with vulvovaginal candidiasis at Ho Chi Minh City Hospital of Dermatology and Venereology. Subject and Methods: A cross-sectional descriptive study. Vaginal discharge samples were collected from 70 women diagnosed with vulvovaginal candidiasis at Ho Chi Minh City Hospital of Dermatology and Venereology from March 2025 to July 2025. The specimens were cultured and identified on Sabouraud dextrose agar and CHROMagar™ Candida media. Antifungal susceptibility testing against azole agents was performed using the broth microdilution method according to the guidelines of the Clinical and Laboratory Standards Institute (CLSI) and the European Committee on Antimicrobial Susceptibility Testing (EUCAST). Results: A total of 73 Candida isolates were obtained: C. albicans 83.6%, C. glabrata 9.6%, C. tropicalis 4.1%, and C. parapsilosis 2.7%. The median MICs for C. albicans were 0.0625 µg/mL for itraconazole and 0.5 µg/mL for fluconazole, with resistance rates of 50.8% and 16.4%, respectively. Candida non-albicans species exhibited high resistance to both drugs (71.4–100%). Conclusion: C. albicans remains the predominant causative agent of vulvovaginal candidiasis; however, an increasing trend of highly resistant Candida non-albicans species has been observed. Species identification and antifungal susceptibility testing prior to treatment are essential to guide appropriate therapy and help mitigate antifungal resistance in the community.
