Vulvovaginal candidiasis (VVC) is an inflammatory disease of the vulva and vagina caused by different yeasts of the genus Candida which is responsible for infection in pregnant patients who attended Maternidade Escola Januário Cicco, Rio Grande do Norte, Brazil. From 41 samples, 19 yeasts were identified phenotypically as Candida albicans and one as Candida glabrata which is reported as the non-albicans species most frequently isolated from vulvovaginitis. The susceptibility to selected antifungal agents (flucytosine, fluconazole, voriconazole, amphotericin B, caspofungin and micafungin) was determined, and the association between patient-related signs and symptoms aided the construction of an epidemiological profile. Antifungal susceptibility testing performed by automated method showed that all strains were sensitive to the drugs tested, including the C. glabrata specimen despite its known resistance or dose-dependent susceptibility to azole derivatives. Regarding patient signs and symptoms, no statistically significant association between these and the establishment of VVC was found. It can be concluded that the laboratorial diagnosis of VVC is necessary prior to the administration of treatment, since only 48·78% of the patients had VVC but for all of them antifungal therapy were prescribed.
Vulvovaginal candidiasis (VVC) is a problem that affects a significant number of pregnant women worldwide. This type of fungal infection generates great discomfort due to the symptomatology and difficulties of diagnosis and treatment. In view of the scarcity of data in the State of Rio Grande do Norte, Brazil, regarding studies carried out on fungal populations of the genus Candida associated with VVC in pregnant women, this study considered relevant, the phenotypic and genotypic identification of the species, to estimate the prevalence, to determine their susceptibility to the antifungal and to correlate with signs and symptoms.
外阴阴道念珠菌病(VVC)是由念珠菌属的不同酵母菌引起的外阴和阴道炎症性疾病,该疾病导致巴西北里奥格兰德州若昂·西科产科学校就诊的孕妇发生感染。从41份样本中,经表型鉴定有19株酵母菌为白色念珠菌,1株为光滑念珠菌,后者是从外阴阴道炎中最常分离出的非白色念珠菌菌种。测定了这些菌株对所选抗真菌药物(氟胞嘧啶、氟康唑、伏立康唑、两性霉素B、卡泊芬净和米卡芬净)的敏感性,并且患者相关体征和症状之间的关联有助于构建流行病学概况。通过自动化方法进行的抗真菌药敏试验表明,所有菌株对所测试的药物均敏感,包括光滑念珠菌样本,尽管其已知对唑类衍生物耐药或呈剂量依赖性敏感。关于患者的体征和症状,未发现这些与VVC的确诊之间存在统计学上的显著关联。可以得出结论,在进行治疗之前,有必要对VVC进行实验室诊断,因为只有48.78%的患者患有VVC,但所有患者均接受了抗真菌治疗。
外阴阴道念珠菌病(VVC)是一个影响全球大量孕妇的问题。这种真菌感染由于其症状以及诊断和治疗的困难而产生极大不适。鉴于巴西北里奥格兰德州关于孕妇中与VVC相关的念珠菌属真菌种群的研究数据稀缺,本研究认为对该菌种进行表型和基因型鉴定、估计患病率、确定其对抗真菌药物的敏感性并与体征和症状相关联具有重要意义。
