摘要:

目的 探讨早期外周血中性粒细胞与淋巴细胞比值(NLR)与急性缺血性脑卒中(AIS)患者静脉溶栓治疗后预后不良及早期神经功能恶化(END)的关系。方法 回顾性纳入行静脉溶栓治疗的AIS患者221例,收集患者的一般资料、既往疾病史、临床及影像学相关资料。治疗前采集肘静脉血进行血常规检测,并计算NLR。主要研究终点为发病3个月预后不良或死亡,次要终点为静脉溶栓后24 h内出现症状性颅内出血(SICH)或END。采用Logistic回归分析发生主要及次要研究终点事件的影响因素,受试者工作特征(ROC)曲线分析NLR对临床结局的预测价值。结果 Logistic回归分析显示,女性、高血压、较高的基线NLR(OR=1.968,95%CI:1.516~2.555,P<0.001)和美国国立卫生研究院卒中量表(NIHSS)评分是患者3个月预后不良的独立危险因素;女性、既往卒中或短暂性脑缺血发作、较高的随机血糖、较高的基线NLR(OR=1.317,95%CI:1.028~1.688,P=0.030)和NIHSS评分是患者3个月死亡的独立危险因素;高血压、较高的同型半胱氨酸、较高的基线NLR(OR=1.420,95%CI:1.180~1.709,P<0.001)和NIHSS评分是END的独立危险因素。SICH组(n=5)NLR水平与非SICH组(n=216)差异无统计学意义。ROC曲线分析结果显示,基线NLR对AIS患者3个月预后不良、3个月死亡及END的预测价值较高[曲线下面积分别为0.748(95%CI:0.679~0.817)、0.738(95%CI:0.622~0.853)和0.730(95%CI:0.656~0.804)],对SICH无预测价值。高NLR组(NLR≥2.63,n=89)基线NIHSS评分、随机血糖、合并高血压、冠心病、END、3个月预后不良和死亡的比例高于低NLR组(NLR<2.63,n=132)。结论 基线NLR升高与AIS患者静脉溶栓治疗后发生END及3个月预后不良相关,有望成为预测AIS患者临床转归的生物标志物。

Abstract:

Objective To investigate the relationship between the early neutrophil-to-lymphocyte ratio (NLR) in peripheral blood, poor prognosis and early neurological deterioration (END) in patients with acute ischemic stroke (AIS) following intravenous thrombolysis treatment. Methods The retrospective study included 221 AIS patients who underwent intravenous thrombolysis therapy. Demographic information, medical history, clinical and imaging data were collected. Peripheral venous blood samples were drawn before treatment for routine blood tests, and NLR was calculated. The primary endpoint was poor prognosis or death at 3 months after onset, and the secondary endpoint was symptomatic intracranial hemorrhage (SICH) or END within 24 hours after thrombolysis. Logistic regression was used to analyze factors associated with the primary and secondary endpoint events. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the predictive value of NLR for clinical outcomes. Results Logistic regression analysis revealed that female, hypertension, higher baseline NLR (OR=1.968, 95%CI: 1.516-2.555, P<0.001) and NIHSS scores were independent risk factors for 3-month poor outcomes in AIS patients. Female, a history of stroke or transient ischemic attack (TIA), higher random blood glucose, elevated baseline NLR (OR=1.317, 95%CI: 1.028-1.688, P=0.030) and NIHSS scores were independent risk factors for 3-month mortality. Hypertension, elevated homocysteine, higher baseline NLR (OR=1.420, 95%CI: 1.180-1.709, P<0.001) and NIHSS scores were independent risk factors for END. There was no significant difference in NLR level between the SICH group (n=5) and the non-SICH group (n=216). ROC curve analysis showed that baseline NLR had high predictive value for 3-month poor outcomes, 3-month mortality and END in AIS patients, with AUCs of 0.748 (95%CI: 0.679-0.817), 0.738 (95%CI: 0.622-0.853) and 0.730 (95%CI: 0.656-0.804), respectively. There was no predictive value for SICH. Patients in the high NLR group (NLR≥2.63, n=89) had significantly higher baseline NIHSS scores, random blood glucose levels and rates of hypertension, coronary artery disease, END, 3-month poor outcomes and 3-month mortality compared to those in the low NLR group (NLR<2.63, n=132). Conclusion Elevated baseline NLR is associated with the occurrence of END and 3-month poor outcomes in AIS patients following intravenous thrombolysis therapy, suggesting its potential as a biomarker for predicting clinical outcomes in AIS patients.
