摘要(Abstract):
目的探讨血清降钙素原检测对小儿脑膜炎的鉴别诊断价值。方法采用免疫增强比浊法检测65例细菌性脑膜炎患儿,41例病毒性脑膜炎患儿,40例健康对照个体的血清降钙素原水平。结果 (1)细菌性脑膜炎组、病毒性脑膜炎组、健康对照组的血清降钙素原水平不全相等(P<0.05);细菌性脑膜炎组的血清降钙素原水平显著高于病毒性脑膜炎组、健康对照组(P<0.05);病毒性脑膜炎组与健康对照组的血清降钙素原水平差异无统计学意义(P>0.05)。(2)将病毒性脑膜炎组与健康对照组的数据合并,以血清降钙素原水平≥0.5ng/L作为细菌性脑膜炎的诊断cut-off值,其诊断灵敏度、特异度、阳性预测值、阴性预测值、诊断准确度分别为100.0%、98.8%、98.5%、100.0%、99.3%。结论血清降钙素原检测有助于细菌性脑膜炎的诊断与鉴别诊断。
