颅内感染患儿血及脑脊液β-内啡肽及C-反应蛋白的变化

Changes of Cerebrospinal Fluid β-Endorphin and C-Reactive Protein in Children with Central Nervous System Infection

目的探讨颅内感染患儿联合检测血及脑脊液(CSF)β-内啡肽(-βEP)及C-反应蛋白(CRP)的临床意义。方法65例确诊颅内感染患儿为观察组,其中病毒性脑炎组(病脑组)48例,化脓性脑膜炎组(化脑组)12例,结核性脑膜炎组(结脑组)5例,用放射免疫法分别测定急性期及恢复期血及CSF中-βEP及CRP含量;另外24例有神经系统表现但非颅内感染患儿作为对照组。结果感染早期观察组血及CSF中-βEP含量均明显升高,高于对照组;恢复期上述指标明显下降。化脑组与病脑组、结脑组及对照组比较,血清CRP浓度在急性期明显升高,恢复期明显下降;而病脑组和结脑组始终在正常范围;各组CSFCRP浓度在急性期及恢复期无明显变化。结论测定血及CSF中-βEP含量有助于早期诊断颅内感染,同时检测血清CRP有助于早期鉴别化脓性及非化脓性感染。

Objective To determine the changes of cerebrospinal fluid（CSF） β-endorphin（β-EP） and C-reactive protein（CRP） in children with central nervous system（CNS） infection. Methods Sixty-five children suffered from CNS infection were determined the plasma and CSF β-EP and CRP concentration during the acute and recovering stage with radioimmunoassay, which included 48 viral encephalitis, 12 purulent meningitis and 5 tuberculou meningitis,and 24 non-CNS disease children were as control group. Results The concentrations of plasma and CSF β-EP of every experimental group were obviou.sly higher than those of control group during the early stage of CNS infection and these were obviously lower during the recovering stage. The serum concentration of CRP during acute stage was significantly higher than that during recovering stage. No change of serum and CSF CRP concentration was determined during either the acute or recovering stage in the other two experimental groups. Conclusions Determining the plasma and CSF β-EP is meaningful in early diagnosis of CNS infection,and determining the serum CRP at the ,same time may be helpful in differentiating septic and inseptic infection.
