目的分析小婴儿化脓性脑膜炎的临床特点,探讨其预测因子。方法回顾性分析我科2015—2017年53例小月龄化脓性脑膜炎患儿的临床资料。以同时期、同年龄层的细菌感染患儿81例为观察组。通过单因素和多因素分析进行两组比较。结果单因素分析提示早产儿、激惹、嗜睡、前囟紧张、颈强直及循环不良方面有差异。脑脊液白细胞数量、蛋白浓度、糖浓度,糖与同期血糖比值以及乳酸脱氢酶浓度均有明显差异。多因素分析提示仅脑脊液蛋白及乳酸脱氢酶有统计学意义。受试者工作曲线显示脑脊液蛋白、乳酸脱氢酶及两项指标合并的诊断效能均较高。结论小婴儿化脓性脑膜炎患儿缺乏典型表现,密切关注早产儿基础疾病,激惹、嗜睡、前囟紧、颈强直及循环不良的临床表现,脑脊液蛋白及乳酸脱氢酶等实验室指标,有利于早期识别,及时干预,减少不良事件的发生。

Objective We aimed to analyze the clinical characteristics of community acquired purulent meningitis(PM) in infants and explore the predictors of early diagnosis. Methods Retrospective study was done with patients in our NICU from Jan 2015 to Dec 2017 aged during 29 days to 90 days. We divided them into two groups, 53 of which diagnosed PM were included as a case group, while 81 of which admitted inpatients with fever at the same periods and in the same age ranges were included as a control group. Factors including adverse basic events, clinical manifestations, laboratory examinations and so on were compared between two groups. Results Univariate analysis showed that premature, manifestations such as irritability, lethargy, bulging fontanelle,a stiff neck and the poor circulation, and cerebrospinal fluid(CSF) data like the mount of white blood cell, concentration of CSF protein, concentration of CSF glucose, CSF/blood glucose ratio, concentration of CSF lactate dehydrogenase were different between two groups. In the multivariate analysis, concentration of CSF Protein(＞0.450 g/L, OR=5.819, P=0.002) and concentration of CSF lactate dehydrogenase(＞28.300 U/L,OR=7.892, P＜0.001) were proven to be independent risk factors for the diagnosis of PM. Receiver operating characteristic (ROC) analysis revealed that the CSF protein, the CSF lactate dehydrogenase and the combination of the two factors had an increased area under the curve (AUC), the mounts of each which were 0.839,0.867 and 0.890. Conclusion Patients with PM in early infantile period are often lack of atypical clinical characteristics. We need pay highly attention to the adverse basic events, irritability, lethargy, bulging fontanelle,a stiff neck, poor circulation and CSF results. The independent predictors for early diagnosis were concentration of CSF protein and lactate dehydrogenase. It indicates that if the predictors could be identified early, diagnosis could be made timely and interventions could be operated immediately. It will be beneficial for progression-free and overall survival.
