species are one of the commonest causes of vaginitis in healthy women of reproductive age. Vulvovaginal candidiasis (VVC) is characterized by vulvovaginal itching, redness and discharge. , which is a common genito-urinary tract commensal, has been the prominent species and remains the most common fungal agent isolated from clinical samples of patients diagnosed with VVC. In recent times, however, there has been a notable shift in the etiology of candidiasis with non- (NAC) species gaining prominence. The NAC species now account for approximately 10% to as high as 45% of VVC cases in some studies. This is associated with treatment challenges and a slightly different clinical picture. NAC species vaginitis is milder in presentation, often occur in patients with underlying chronic medical conditions and symptoms tend to be more recurrent or chronic compared with vaginitis. is the most common cause of NAC-VVC. , , , and are the other commonly implicated species. Treatment failure is common in NAC-VVC, since some of these species are intrinsically resistant or show low susceptibilities to commonly used antifungal agents. This article reviews the etiology, pathogenesis, clinical features, diagnosis, and management of NAC vulvovaginitis.
念珠菌属是育龄健康女性阴道炎最常见的病因之一。外阴阴道念珠菌病(VVC)的特征为外阴阴道瘙痒、发红和分泌物增多。白色念珠菌是常见的泌尿生殖道共生菌,一直是主要菌种,并且仍然是从诊断为VVC的患者临床样本中分离出的最常见真菌病原体。然而,近年来,念珠菌病的病因发生了显著变化,非白色念珠菌(NAC)菌种日益突出。在一些研究中,NAC菌种现在占VVC病例的约10%至高达45%。这与治疗挑战以及略有不同的临床表现有关。NAC菌种阴道炎表现较轻,常发生于有潜在慢性疾病的患者,与白色念珠菌阴道炎相比,症状往往更易复发或呈慢性。光滑念珠菌是NAC-VVC最常见的病因。热带念珠菌、近平滑念珠菌、克柔念珠菌和葡萄牙念珠菌是其他常见的相关菌种。NAC-VVC治疗失败很常见,因为其中一些菌种对常用抗真菌药物具有固有抗性或敏感性较低。本文综述了NAC外阴阴道炎的病因、发病机制、临床特征、诊断和管理。
