ABSTRACT: Background: Vulvovaginal candidiasis (VVC) is a common cause of significant morbidity, affecting millions of women worldwide. It is estimated that approximately 75%of women of childbearing age will have at least one episode of candidiasis in their lifetime. In the last decades, resistance to azoles has become a public health problem. Although studies on vulvovaginitis have been done, there is lack of VVC studies in our area. The aim of this study was to describe the etiological and resistance profiles of vulvovaginal candidiasis to standard antifungus at the Saint Camille Hospital of Ouagadougou (HOSCO), Burkina Faso. Methods: We conducted a prospective study from January 2018 to December 2022. From vulvovaginal swabs, Candida species were identified using the ChromID® Candida Agar medium and the API® Candida gallery. Antifungal susceptibility testing was performed using Kirby-Bauer agar disk diffusion. Results: A total of 4789 women were sampled. The average age of sexually active women was 27.80+/−6.77 years, with extremes ranging from 15 to 64 years. Vaginal Candida infections accounted for 74.16% of the cases. The 20 - 29 age group was the most affected by vulvovaginal candidiasis. Pregnant women accounted for 28.76% of our study population. Women in the second (2nd) trimester of pregnancy had more Candida infections. Candida albicans was the most isolated species (55.12%), followed by Candida glabrata (27.64%), Candida tropicalis (6.91%), Candida famata (6.67%), Candida krusei (2.56%). All the Candida species isolated showed very high of resistance to Fluconazole (45.2%), Miconazole (23.7%) and Clotrimazole (45.7%). Conclusion: Species-specific antifungal results should always be considered to avoid antifungal resistance associated with vulvovaginal candidiasis. Identifying the causative species using vaginal fungal cultures can help guide therapy and improve outcomes for these patients.
