Recurrent vulvo-vaginal candidiasis in Abidjan (Cote d'Ivoire): Aetiology and associated factors

Recurrent vulvovaginal candidiasis (RVVC) is a major health problem for sexually active women because of its severe effect on their quality of life. A thorough knowledge of their epidemiology leads to their efficient management. Therefore, a cross-sectional study was conducted in 2014 in women with leucorrhoea associated or not with other clinical signs. Recurrence was based on the occurrence of at least four annual episodes of Candida vulvo-vaginitis. An individual interview based on a questionnaire was conducted to identify the socio-demographic parameters that could be associated with the RVVC. Vaginal samples were collected at the obstetrical gynaecology department of the University Hospital of Cocody and at the Pasteur Institute of Cote d'Ivoire. On each sample, a direct examination and culture on Sabouraud-chloramphenicol medium with or without actidione were performed. Yeast identification was performed using chromogenic media (CandiSelect((R))4 [Bio-Rad]) and the study of sugar assimilation using the Auxacolor((R)) 2 gallery (Bio-Rad). A total of 400 patients were included. The average age was 29.2 years (SD = 7.2 years). Of these, 94 had recurrent vulvovaginal candidiasis, with a prevalence of 23.5% (CI95%: 19.49-28.02). Five species of the genus Candida have been identified: Candida albicans (59.6%), Candida glabrata (19.1%), Candida tropicalis (16%), Candida krusei (4.2%) and Candida inconspicua (1.1%). Some factors such as education level, history of sexually transmitted infection, type of underwear used, frequency of personal hygiene and type of product used for these hygiene have been associated with the occurrence of RVVCs. The occurrence of RWCs is relatively high in our study population. Non-albicans Candida species occupy a significant place in this disease epidemiology. By addressing the factors associated with the occurrence and/or persistence of RVVCs, it will be possible to reduce their incidence in sexually active women. (C) 2019 Elsevier Masson SAS.
