Recurrent vulvo-vaginal candidiasis in Abidjan (Côte 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 Côte 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®4 [Bio-Rad]) and the study of sugar assimilation using the Auxacolor® 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 RVVCs is relatively high in our study population. Non-albicansCandida 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.

[Mycological profile of hand onychomycosis amongs "Garba" sellers in Abidjan (Côte d'Ivoire)]. / Profil mycologique des onychomycoses des mains chez les vendeurs de « Garba ¼ à Abidjan (Côte d'Ivoire).

OBJECTIVE: The aim of this study is to determine the prevalence and the fungi involved in onychomycosis located on fingers in Abidjan. MATERIAL AND METHODS: This study includes the sellers of cooked cassava semolina served with fried tuna fish called "garba". Fines squames specimen was processed with 30% KOH for a direct microscope examination. Serous collection were done in physiological serum. Part of the original sample was cultured on Sabouraud medium with antibiotics (chloramphénicol, actidione). Species distribution and antifungal susceptibility by the technique on agar were noted. RESULTS: A total of 205 male sellers were involved. The Onychomycosis prevalence was 6.3%; (95% CI : 3.6-10.3). Five species of yeasts were identified. Candida spp were the most frequent (84.6%) and Candida albicans represented 30.8% of isolated yeasts. Trichosporon cutaneum were isolated in two case (15.4%). Susceptibility for amphotericin-B was 92.3% contrary to 5-fluorocytosine 30.8%. The subjects aged between 15 to 24 (69.2%), with a higher seniority (84.6%) and illiterate (69.2%) were the most affected. The main risk factors of fungal infections were the presence of previous fingernail onychomycosis (P<0.0001) and the frequent fingernail cutting (P=0.0009). CONCLUSION: Onychomycosis caused by yeast is infrequent among "garba" sellers in Abidjan. The main fungi involved in fingernail onychomycosis were Candida species. It is nevertheless necessary to implement sensitization for them on contributing factors.

[Fungal aetiologies and contributing factors of interdigital tinea pedis among policemen in Abidjan (Ivory Coast)]. / Étiologies fongiques et facteurs favorisant les intertrigos inter-orteils chez les gendarmes à Abidjan (Côte d'Ivoire).

AIM OF THE STUDY: Fungal interdigital tinea pedis are poorly documented in Ivory Coast. This study aimed to determine the distribution of fungal species and contributing factors of the disease among policemen in Abidjan. PATIENTS AND METHODS: Our cross-sectional study was carried out at the police school in Abidjan. Our patients consisted of symptomatic or non-symptomatic police students. Samples of scales or serosities taken from inter-toes spaces were examinated with KOH mount and cultured on Sabouraud-chloramphenicol and Sabouraud-chloramphenicol-actidione media. The method of identification depended on the observed fungus. RESULTS: Among the 303 police students with clinical lesions of the inter-toe folds, 233 (76.9%; IC 95%=71.9-81.4) had a positive diagnosis after mycological examination. Lesions were predominantly located in the 3rd and 4th interdigital plantar spaces, with desquamation (100%) followed by maceration (82.5%) as the predominant functional sign. Dermatophytes accounted for 86.3% of the strains isolated with as majority species : Trichophyton interdigitale (40.3%), Microsporum langeronii (30.0%) and Trichophyton rubrum (15.5%). Yeasts accounted for 13.7% of the strains with Candida albicans (7.7%) as the most found species. The duration at the police school (P=0.004) and the practice of sports activities (P=0.0001) were statistically associated with the occurrence of the disease. CONCLUSION: A good hygiene of feet would reduce the incidence of the disease among the defense and security forces. Also, investigations for the influence of the seasons in the occurrence of interdigital tinea pedis will allow a better understand of epidemiology of this dermatomycosis.
