摘要: 目的: 明确荧光染色直接镜检法在口腔念珠菌感染中的应用价值。方法: 纳入263例怀疑口腔念珠菌感染的患者进行真菌培养、荧光染色法直接镜检和氢氧化钾(potassium hydroxide,KOH)镜检。结果: 263例样本中,真菌荧光染色法直接镜检的灵敏度为61.73%,特异度为96.15%,阳性预测值为87.72%,阴性预测值为84.95%,而KOH镜检法的灵敏度为16.67%,特异度为96.32%,阳性预测值为66.67%,阴性预测值为72.35%。使用真菌荧光染色法对口腔扁平苔藓和口腔念珠菌病患者进行检查,发现其灵敏度分别为35.29%和88.46%;而KOH法的灵敏度仅分别为5.88%和35%。结论: 荧光染色直接镜检法灵敏度较高,操作简单、结果迅速,可为临床的诊治工作提供有效的实验室支持。

Abstract: Objective: To clarify the application value of direct microscopy using fluorescence staining method in oral candidal infection. Methods: Two hundred and sixty-three patients suspected of oral candidiasis were included for fungal culture, fluorescence staining direct microscopy, and potassium hydroxide (KOH) microscopy examination. Results: The sensitivity, specificity, the positive predictive value, and the negative predictive value of direct microscopy using fungal fluorescence staining of 263 samples were 61.73%, 96.15%, 87.72%, and 84.95%, respectively. While the sensitivity, specificity, the positive predictive value, and the negative predictive value of KOH microscopy were 16.67%, 96.32%, 66.67%, and 72.35%, respectively. Using fungal fluorescence staining method to examine patients with oral lichen planus and oral candidiasis, the sensitivity was found to be 35.29% and 88.46%, respectively. The sensitivity of KOH method was only 5.88% and 35%, respectively. Conclusion: The fluorescence staining direct microscopy method had high sensitivity, simple operation, and rapid results, which could provide effective laboratory support for clinical diagnosis and treatment.
