Vulvovaginal candidiasis is a yeast infection commonly caused by the overgrowth of Candida species in and around the vulva and vagina. Abnormal vaginal discharge, itching and irritation, swelling and redness of the vaginal area, pain during sexual intercourse, and dyspareunia are important clinical findings of the infection. Currently, the infection is one of the growing burdens to married women. Moreover, the infection with antifungal-resistant Candida species adds challenges to managing the disease. Hence, this study was conducted to identify the different Candida species causing vulvovaginal candidiasis and to determine its susceptibility pattern against different antifungal drugs. A hospital-based cross-sectional and quantitative study was conducted for the period of six months from September 2022 to March 2023 among symptomatic married women in the Gynecology and Obstetrics Department of Bharatpur Hospital, Chitwan. A total of 300 symptomatic cases were enrolled in the study. Candida species were isolated from vaginal swabs following standard microbiological procedures and antifungal susceptibility testing was performed with different antifungal agents. The total prevalence of vulvovaginal candidiasis was found to be 37.3 % (112/300). Among different isolates, Candida albicans was found to be the most predominant (52.6 %), followed by Candida glabrata (29.3 %) among non-albicans. Women from the age group 25-35 years were found to be more infected (47.3 %) and the relationship between contraceptive use and vulvovaginal candidiasis was found to be statistically significant (p < 0.05). Candida species showed higher susceptibility toward Amphotericin-B (68.1 %), followed by fluconazole (Diflucan), and Clotrimazole (50.9 %). Whereas the least susceptibility was observed to Voriconazole (27.6 %) and Itraconazole (35.30 %). Candida albicans was comparatively more susceptible to different antifungal drugs than non-albicans species. Candida parapsilosis was only susceptible to Amphotericin-B and the increasing incidence of vaginal candidiasis due to non-albicans Candida indicates the need for routine speciation of Candida.
外阴阴道念珠菌病是一种酵母菌感染,通常由外阴和阴道内外念珠菌属过度生长引起。异常阴道分泌物、瘙痒和刺激、阴道区域肿胀和发红、性交疼痛及性交困难是该感染的重要临床症状。目前,这种感染是已婚女性日益沉重的负担之一。此外,感染对抗真菌药物耐药的念珠菌属给疾病管理带来了挑战。因此,本研究旨在确定引起外阴阴道念珠菌病的不同念珠菌属,并确定其对不同抗真菌药物的敏感性模式。2022年9月至2023年3月期间,在奇旺巴拉特普尔医院妇产科对有症状的已婚女性进行了一项为期六个月的基于医院的横断面定量研究。共有300例有症状的病例纳入该研究。按照标准微生物学程序从阴道拭子中分离出念珠菌属,并使用不同抗真菌药物进行抗真菌药敏试验。发现外阴阴道念珠菌病的总患病率为37.3%(112/300)。在不同分离株中,白色念珠菌最为常见(52.6%),其次是非白色念珠菌中的光滑念珠菌(29.3%)。发现25 - 35岁年龄组的女性感染率更高(47.3%),且发现使用避孕药与外阴阴道念珠菌病之间的关系具有统计学意义(p < 0.05)。念珠菌属对两性霉素B的敏感性较高(68.1%),其次是氟康唑(大扶康)和克霉唑(50.9%)。而对伏立康唑(27.6%)和伊曲康唑(35.30%)的敏感性最低。白色念珠菌对不同抗真菌药物的敏感性比非白色念珠菌相对更高。近平滑念珠菌仅对两性霉素B敏感,非白色念珠菌引起的阴道念珠菌病发病率增加表明需要对念珠菌进行常规菌种鉴定。
