摘要 目的分析痰涂片查找真菌对肺部念珠菌感染的提示价值。方法根据诊断标准将诊断分为确诊、临床诊断、疑似及排除肺念珠菌病(PC)。痰培养前涂片检查与培养结果及(1-3)-β-D-葡聚糖检测(G试验)结果合并分析。结果 339例痰培养念珠菌阳性的患者,确诊PC 6例,临床诊断43例,疑似99例。排除PC 191例。148例符合PC诊断的患者中89例涂片检出假菌丝,阳性率60.1%。检出假菌丝对PC诊断敏感性为60.1%、特异性为94.3%、阳性预测值(PPV)为89.0%、阴性预测值(NPV)为75.4%,诊断准确性为79.4%;G试验敏感性、特异性、PPV、NPV和诊断准确性分别为71.0%、83.8%、77.2%、78.9%和78.2%。结论痰培养前涂片检出假菌丝对肺部念珠菌感染有重要的提示价值,尤其要关注同时G试验持续阳性者。
