摘要 目的:探讨N末端B型脑钠肽前体(NT-proBNP)、降钙素原(PCT)在肺部感染中的临床应用价值。方法:通过检测肺部感染64例和非感染对照组85例的血清NT-proBNP浓度及PCT,并对各组间进行比较,利用ROC曲线以评价NT-proBNP及PCT诊断肺部感染的准确性。结果:肺部感染组NT-proBNP及PCT浓度明显高于非感染对照组,NT-proBNP、PCT评估肺部感染的ROC曲线下面积分别为0.736(95%置信区间0.638~0.834)、0.658(95%置信区间0.562~0.755),最佳临界值为464.09pg/ml、0.538ng/ml,敏感性为52.6%、45.2%,特异性为96.9%、98%。结论:及时监测NT-proBNP、PCT对评估肺部感染的病情变化、早期诊断和治疗具有重要临床价值。
