ABSTRACT

Background

The epidemiology of vulvovaginal candidiasis (VVC) in Greece remains poorly reported and outdated.

Objectives

We therefore conducted a 2‐year retrospective survey to assess the epidemiological aspects of the infection among symptomatic Greek patients.

Patients/Methods

High vaginal swab samples were collected from adult women with clinically suspected VVC attending a private diagnostic laboratory in Athens. VVC was confirmed through microscopic examination of a wet mount preparation revealing yeasts and Candida‐positive culture. Species were identified by MALDI‐ToF MS, and in vitro susceptibility was determined according to the EUCAST‐E.Def 7.4. Predisposing host factors were associated with the occurrence of the infection and isolated Candida spp. using Fisher's exact test, and epidemiological changes over time were analysed with the χ2 test for trend.

Results

Among 1300 women screened, 283 VVC episodes were recorded among 233 (18%) patients, whereof 11 (5%) had recurrent VVC (RVVC) and 19 (8%) had mixed Candida infections. Coinfection with other pathogens and recent prior use of antifungals were associated with RVVC. Candida albicans was the most prevalent pathogen (50%), followed by Candida parapsilosis sensu stricto (SS) (35%), Nakaseomyces glabratus (former Candida glabrata) (10%), Pichia kudriavzevii (former Candida krusei) (3%), Candida orthopsilosis (1.5%) and Clavispora lusitaniae (former Candida lusitaniae) (0.5%). Regarding the RVVC cases, 54% were attributed to C. albicans, 37% to N. glabratus and 9% to C. parapsilosis SS. Resistance to fluconazole was found in 4% of C. albicans and 23% of N. glabratus strains with cross‐resistance to other azoles. Fluconazole‐resistant isolates were recovered from 5 of 11 RVVC patients, whereof 4 of 5 had previous exposure to azoles. During the study period, an increase in N. glabratus VVC and fluconazole resistance was noted.

Conclusions

VVC is common in our region, with C. albicans as the predominant species, followed by C. parapsilosis SS and N. glabratus. Fluconazole resistance is low in C. albicans but high in N. glabratus, emphasising the need for targeted antifungal strategies.
