中枢神经系统感染患者脑脊液中可溶性白介素-2受体和可溶性细胞间黏附分子-1水平及其临床意义

目的观察在不同病因所致中枢神经系统（CNS）感染患者的脑脊液（CSF）中可溶性白介素-2受体（sIL-2R）和可溶性细胞间黏附分子-1（sICAM-1）水平变化并探讨其临床意义。方法采用ELISA法检测25例结核性脑膜炎（结脑）、15例化脓性脑膜炎（化脑）和25例病毒性脑膜炎（病脑）患者急性期脑脊液中sIL-2R和sICAM-1的水平并与对照组（20例头痛患者）比较,同时将重症患者和轻症患者进行比较。结果急性期CNS感染各组脑脊液中sIL-2R、sICAM-1水平均高于对照组,差异有统计学意义（P〈0.05）,sIL-2R水平结脑组高于化脑组和病脑组,sICAM-1水平结脑组、化脑组高于病脑组,差异均有统计学意义（P〈0.05）;重症组脑脊液中sIL-2R、sICAM-1水平高于轻症组,差异均有统计学意义（P〈0.05）。结论sIL-2R和sICAM-1参与了CNS感染的病理过程,sIL-2R和sICAM-1水平与病情轻重有关,脑脊液中sIL-2R水平有助于结脑与化脑、病脑的鉴别诊断;脑脊液中sICAM-1水平可能在病脑与结脑、化脑的鉴别诊断中有价值。

Levels of sIL-2 Receptor and sICAM-1 in Cerebrospinal Fluid and Their Clinical Significance in Patients with Central Nervous System Infection

Objective To explore the changes of sIL-2R and sICAM-1 levels in cerebrospinal fluid(CSF) and their significance in patients with infection of central nervous system(CNS).Methods The levels of sIL-2R and sILCAM-1 were determined by ELISA in acute-phase CSF of 25 patients with tuberculous meningitis(TBM),15 with purulent meningitis(PM),25 with viral meningitis(VM) and 20 normal subjects,and a comparison was carried out between severe,mild patients.Results The levels of sIL-2R,sICAM-1 in acute-phase CSF were ...
