摘要
目的:评价血浆1-3-β-D葡聚糖检测诊断侵袭性肺部真菌感染临床应用价值。方法:分析2009年1月-2010年6月我院送检的99例气管镜吸引痰标本,其中真菌培养阳性者32例,真菌培养阴性者67例。99例患者同时进行血浆1-3-β-D葡聚糖检测,分析比较两组葡聚糖水平,应用ROC曲线评价1-3-β-D葡聚糖诊断肺部真菌感染的临床价值。结果:肺部真菌培养阳性组1-3-β-D葡聚糖水平明显明显高于阴性组(34.7.6±20.0 vs 10.4±6.9,t=8.9 P<0.0001);血浆1-3-β-D葡聚糖诊断肺部真菌感染的ROC曲线下面积为0.89(95%CI:0.82%~0.96%);以20 ng/L为Cutt-off值诊断肺部真菌感染的敏感度为92.4%(95%CI:83.2%~97.5%),特异度为75.0%(95%CI:56.6.2%~88.5%)。结论:痰培真菌沛养阳性患者血浆葡聚糖水平明显升高,其诊断肺部真菌感染有一定的临床参考价值。
Objective:To evaluate the clinical value of plasma 1-3-β-D glucan in diagnosis of invasive pulmonary fungal infection.Methods: 99 sputum specimens were collected for fungal cultivation from January 2009 to June 2010 in our hospital.32 specimens were fungal cultivation positive and 67 were negative.The plasm 1-3-β-D glucan of the patients were tested for comparison between the two groups.The ROC curve was used to evaluate the diagnosis effect of plasm 1-3-β-D glucan.Results: The plasm 1-3-β-D glucan level was much higher in fungal cultivation positive group compared with fungal cultivation negative group(34.7.6±20.0 vs 10.4±6.9,t=8.9 P〈0.0001).The under-curve-area(AUC) of plasm 1-3-β-D glucan for diagnosis of pulmonary fungal infection was 0.89(95%CI:0.82%~0.96%).The sensitivity and specificity was 92.4%(95%CI:83.2%~97.5%)and 75.0%(95%CI:56.6.2%~88.5%)at the cutt-off level of 20 ng/L.Conclusion: The plasm 1-3-β-D glucan was elevated in the fungal cultivation positive group.It can provide some diagnosis information for testing plasm 1-3-β-D glucan.
