中文摘要: 目的  分析脑脊液腺苷脱氨酶(ADA)、基质金属蛋白酶9(MMP-9)和α2巨球蛋白(A2M)水平联合MRI影像学特征在评估新生儿化脓性脑膜炎(PM)预后中的价值。方法  回顾性选取2022 年5 月至2025 年3 月徐州市中心医院收治的PM 患儿为研究对象,收集患儿一般资料、脑脊液生物标志物水平以及MRI 影像学结果。采用logistic 回归方程分析患儿预后与脑脊液生物标志物以及MRI 特征的关系,绘制受试者工作特征(ROC)曲线评价预后预测价值。结果  共89 例PM 患儿纳入研究,根据格拉斯哥预后量表(GOS)评分是否≥5 分将患儿分为预后良好组(n=64)和预后不良组(n=25)。预后不良组脑脊液A2M、MMP-9 和ADA 水平均高于预后良好组(P<0.01)。预后不良组硬膜下积脓、脑室周围白质减少、脑室内出血以及脑室管膜增厚占比均高于预后良好组(P<0.05)。多因素logistic 回归分析结果显示,高A2M(OR=1.399,95%CI:1.162~1.684)、高MMP-9(OR=1.034,95%CI:1.004~1.065)、高ADA(OR=2.010,95%CI:1.227~3.294)、硬膜下积脓(OR=3.976,95%CI:1.053~15.016)、脑室周围白质减少(OR=5.480,95%CI:1.350~22.244)、脑室内出血(OR=8.702,95%CI:2.300~32.929)以及脑室管膜增厚(OR=7.369,95%CI:2.077~26.143)是PM 患儿预后不良的独立危险因素(P<0.05)。ROC 分析结果显示,以上指标联合预测PM 患儿预后的价值最高,曲线下面积(AUC)为0.934,灵敏度为88.00%,特异度为95.30%。结论  脑脊液A2M、MMP-9、ADA联合MRI影像学特征在新生儿PM预后中具有较高的预测效能,可为临床诊疗提供指导。
Abstract:Objective To analyze the value of cerebrospinal fluid(CSF)levels of adenosine deaminase(ADA),matrix metalloproteinase - 9(MMP - 9),and alpha - 2 - macroglobulin(A2M)combined with MRI features in evaluating the prognosis of neonatal purulent meningitis(PM). Methods A retrospective study was conducted on neonates with PM admitted to Xuzhou Central Hospital from May 2022 to March 2025. General data,CSF biomarker levels,and MRI findings were collected. Logistic regression was used to analyze the relationship between prognosis and CSF biomarkers as well as MRI features. Receiver operating characteristic(ROC)curves were plotted to evaluate the predictive value for prognosis. Results A total of 89 neonates with PM were included and divided into a good prognosis group(n=64)and a poor prognosis group(n=25)based on Glasgow Outcome Scale(GOS)score(≥5 or <5). The poor prognosis group had significantly higher CSF levels of A2M,MMP - 9,and ADA than the good prognosis group (P<0.05). The proportions of subdural empyema,periventricular white matter reduction,intraventricular hemorrhage,and ependymal thickening were significantly higher in the poor prognosis group than those in the good prognosis group(P<0.05).Multivariate logistic regression showed that high A2M(OR=1.399,95%CI:1.162-1.684),high MMP-9(OR=1.034,95%CI:1.004-1.065),high ADA(OR=2.010,95%CI:1.227-3.294),subdural empyema(OR=3.976,95%CI:1.053- 15.016),periventricular white matter reduction (OR=5.480,95% CI:1.350- 22.244),intraventricular hemorrhage(OR=8.702,95%CI:2.300-32.929),and ependymal thickening(OR=7.369,95%CI:2.077-26.143)were independent risk factors for poor prognosis in children with PM(P<0.05). ROC analysis showed that the combination of these indicators had the highest predictive value for prognosis,with an area under the curve(AUC)of 0.934,sensitivity of 88.00%,and specificity of 95.30% . Conclusion The combination of CSF A2M,MMP - 9,and ADA with MRI imaging features has high predictive efficacy for the prognosis of neonatal PM,and can provide guidance for clinical diagnosis and treatment.
