Pregnant women have an increased risk of vulvovaginal candidosis. Recurrent candidosis is under debate as a contributor to preterm birth, and vertical transmission may cause diaper dermatitis and oral thrush in the newborn. Apart from cultural methods, the gold standard for diagnosing candidosis is Gram staining, which is time-consuming and requires laboratory facilities. The objective of this prospective study was to validate a point-of-care vaginal yeast detection assay (™ ) and to evaluate it in asymptomatic pregnant women. We enrolled 200 participants, 100 of whom had vulvovaginal candidosis according to Gram stain (study group) and 100 were healthy pregnant controls (control group). Of these, 22 participants (11%) had invalid test results. The point-of-care test of the remaining 85 and 93 study participants in the study and control groups, respectively, showed a sensitivity of 94.1%, specificity of 98.9%, positive predictive value of 90.3%, and negative predictive value of 99.4% when compared with Gram stain. In conclusion, we found a high correlation between the ™ and Gram-stained smears during pregnancy. This suggests a potential role of this point-of-care test as a screening tool for asymptomatic pregnant women in early gestation.
孕妇患外阴阴道念珠菌病的风险增加。复发性念珠菌病是否会导致早产仍存在争议,垂直传播可能会导致新生儿尿布皮炎和鹅口疮。除了培养方法外,诊断念珠菌病的金标准是革兰氏染色,但这种方法耗时且需要实验室设备。这项前瞻性研究的目的是验证一种即时检验阴道酵母菌检测方法(™),并在无症状孕妇中对其进行评估。我们招募了200名参与者,其中100名根据革兰氏染色诊断为外阴阴道念珠菌病(研究组),100名是健康的孕妇对照组(对照组)。其中,22名参与者(11%)的检测结果无效。分别对研究组和对照组中其余85名和93名研究参与者进行的即时检验显示,与革兰氏染色相比,其敏感性为94.1%,特异性为98.9%,阳性预测值为90.3%,阴性预测值为99.4%。总之,我们发现孕期™检测结果与革兰氏染色涂片之间具有高度相关性。这表明这种即时检验方法有可能作为孕早期无症状孕妇的筛查工具。
