影响病毒性脑炎近期预后的相关危险因素分析

目的 探讨影响病毒性脑炎近期预后的相关危险因素.方法 回顾性分析124例病毒性脑炎患者的临床资料,应用格拉斯哥预后量表(COS)分级将患者分为预后良好组(89例)和预后不良组(35例).并选取14个危险因素进行Logistic回归分析.结果 单因素分析表明,抽搐持续时间、意识障碍、局灶性神经功能缺损,头颅MRI异常、脑电图重度异常与病毒性脑炎近期预后有显著相关性(P＜0.05);而年龄、性别、精神行为异常、脑膜刺激征、脑脊液(CSF)压力、CSF白细胞数、CSF蛋白、外周血白细胞计数、头颅CT异常与病毒性脑炎近期预后无显著相关性(P＞0.05).多因素分析表明,抽搐持续时间(OR=2.877,P=0.005)和头颅MRI异常(OR=16.582,P=0.008)为影响病毒性脑炎近期预后的独立危险因素.结论 病毒性脑炎的预后是多因素共同作用的结果,头颅MRI异常和抽搐持续时间是影响病毒性脑炎近期预后的独立危险因素.

Abstract：

Objective To investigate the risk factors of short-term prognosis in patients with viral encephalitis. Methods Clinical data of 124 patients with viral encephalitis were analyzed retrospectively. All patients were divided into good prognosis group and poor prognosis group according to the Glasgow outcome scale. Fourteen related risk factors were chosen and multifactor Logistic regression analysis was made. Results Univariate analysis showed, the duration of seizure, consciousness disorder, deficiency of cranial nerves, severe abnormal electroencephalogram and abnormal cranial MRI had significant correlation with short-term prognosis (P＜0.05), but age, sex,behavior disorder, meningeal irritation sign, pressure of cerebrospinal fluid (CSF), leukocyte number of CSF, protein level of CSF, peripheral white blood cell, and abnormal cranial CT had no correlation with short-term prognosis (P ＞0.05). Multivariate analysis showed that the abnormal of cranial MRI and the duration of seizure were the independent risk factors of short-term prognosis. Conclusions The short-term prognosis of viral encephalitis relates with many factors. The abnormal cranial MRI and the duration of seizure are the important related risk factors.
