摘要:

目的 探讨中性粒细胞-淋巴细胞比值(NLR)和红细胞分布宽度(RDW)与小儿高热惊厥所 致脑损伤的关系。方法 搜集 2017 年 4 月至 2019 年 8 月我院治疗的高热惊厥患儿 212 例,根据患儿临床 表现分为单纯组(126 例,单纯型高热惊厥)和复杂组(86 例,复杂型高热惊厥),另选取我院门诊接收的发 热但无惊厥患儿 86 例作为发热无惊厥组。比较 3 组患儿血常规检测指标水平,绘制 ROC 曲线,分析 NLR、 RDW 对单纯型和复杂型高热惊厥的鉴别诊断价值;依据患儿是否并发脑损伤将 212 例高热惊厥患儿分为 脑损伤组(n = 30)和无脑损伤组(n = 182),绘制 ROC 曲线,分析 NLR、RDW 与小儿高热惊厥所致脑损伤的 关系。结果 单纯组和复杂组患儿 WBC、RBC、NLR 及 RDW 水平均高于发热无惊厥组,复杂组患儿 NLR 及 RDW 水平均高于单纯组(均 P < 0.05)。ROC 曲线分析结果显示,NLR 对单纯型和复杂型高热惊厥的诊 断灵敏度和特异度分别为 70.05%和 65.55%,曲线下面积(AUC)为 0.766;RDW 分别为 68.77%、60.04%, AUC 为 0.748。logistic 回归分析结果显示,外周血 NLR 及 RDW 水平与高热惊厥患儿并发脑损伤呈正相关 (P < 0.05);ROC 曲线分析结果显示,NLR 对高热惊厥患儿并发脑损伤的诊断灵敏度和特异度分别为 75.40%和 70.06%,AUC 为 0.848;RDW 分别为 77.70%、68.88%,AUC 为 0.870。结论 高热惊厥患儿外周血 NLR 和 RDW 水平异常升高,且复杂型高热惊厥患儿外周血中 NLR 和 RDW 水平明显高于单纯型高热惊 厥,伴有脑损伤时其 NLR 和 RDW 水平升高更明显,临床可通过外周血 NLR 和 RDW 水平鉴别诊断患儿高 热惊厥类型,并预测是否伴有脑损伤的发生

Abstract:

Objective There is no research on the relationship between neutrophil to lymphocyte ratio (NLR)and red blood cell distribution width(RDW)and brain damage caused by febrile convulsions in children. Therefore,this study was aimed to explore the expression of NLR and RDW in febrile convulsions in children,and to analyze its relationship with brain damage. Methods A total of 212 children with febrile seizurestreated in our hospital from April 2017 to August 2019 wereselectedand divide into simple group(n = 126,simple febrile seizures and complex group(n = 86,complex febrile seizures)according to their clinical manifestations,another 86 children with fever but no convulsions received in the outpatient department of our hospital were selected as the fever but with no convulsions group. The blood routine test index levels of the 3 groups were compared ,the differential diagnosis value of NLR,RDW for simple and complex febrile seizures were analyzed using ROC curve;a total of 212 cases of febrile seizures were divided into brain injury group(n = 30)and no brain injury group(n = 182 according to whether the children complicatedbrain injury,the relationship between NLR,RDW and brain injury caused by febrile convulsion in children were analyzed using ROC curve. Results The levels of WBC,RBC NLR and RDW in the simple group and the complex group were higher than those in the fever butwith no convul⁃ sions group,and the levels of NLR and RDW in the complex group were higher than those in the simple group(all P < 0.05). ROC curve analysis results showed that the diagnostic sensitivity and specificity of NLR for simple and complex febrile convulsions were 70.05% and 65.55%,area under the curve(AUC)was 0.766;RDW was 68.77% 60.04% and 0.748,respectively. Logistic regression analysis showed peripheral blood levels of NLR and RDW were positively correlated with brain injury in children with febrile seizures (P < 0.05);ROC curve analysis showed that the sensitivity and specificity of NLR for the diagnosis of brain injury in children with febrile seizures were 75.40% and 70.06%,AUC was 0.848;RDW was 77.70%,68.88% and 0.870,respectively. Conclusions The levels of NLR and RDW in the peripheral blood of children with febrile seizures are abnormally increased,and the levels of NLR and RDW in the peripheral blood of children with complex febrile seizures are significantly higher than those of simple febrile seizures,and thelevels of NLR and RDW increase when accompanied with brain injury more obviously,the level of peripheral blood NLR and RDW could be used to differentially diagnose the types of febrile convulsions in children and predict whether it is accompanied by brain injury.
