摘要: 背景 全身炎症反应指数(SIRI)是一种较新的炎症生物标志物,其与缺血性脑卒中患者复发的关系尚不明确。 目的 探讨SIRI水平与缺血性脑卒中患者1年内复发的关联性。 方法 选取2019年3月—2021年3月在南昌大学第一附属医院、南昌大学第二附属医院、南昌市第二医院和南昌市第三医院住院且确诊为缺血性脑卒中的患者作为研究对象进入队列,并对其随访1年。收集患者入院后48 h内的基线信息、随访过程中的缺血性脑卒中复发情况。采用Cox比例风险回归模型、限制性立方样条、亚组分析探讨SIRI与缺血性脑卒中患者1年内复发之间的关联性。 结果 本研究纳入了1 023例患者,在1年随访期间共107例(10.46%)复发。多因素Cox比例风险回归模型分析结果显示,在调整变量后,SIRI升高是缺血性脑卒中复发的危险因素(HR=1.06,95%CI=1.01~1.10,P<0.05)。将SIRI按四分位数分类时,与Q1亚组(256例)相比,Q4亚组(256例)有较高的缺血性脑卒中复发风险(HR=1.80,95%CI=1.08~3.00,P<0.05)。限制性立方样条分析结果显示,SIRI与缺血性脑卒中复发风险呈J型的剂量-反应关系(PNonlinear=0.025)。进一步按性别、年龄、既往脑卒中、入院时美国国立卫生研究院卒中量表(NIHSS)评分分层进行亚组分析,结果显示,SIRI和入院时NIHSS评分分层存在交互作用(P<0.001),在NIHSS评分为0~1分时,SIRI(HR=1.25,95%CI=1.04~1.51,P=0.020)与缺血性脑卒中复发存在相关关系;在NIHSS评分为5~15分时,SIRI(HR=1.20,95%CI=1.12~1.28,P<0.001)与缺血性脑卒中复发存在相关关系;在上述评分区间SIRI升高与缺血性脑卒中复发风险增加有关。 结论 较高的SIRI与缺血性脑卒中复发风险增加明显相关。在SIRI与缺血性脑卒中复发之间观察到J型关联,且在NIHSS评分为0~1、5~15分的缺血性脑卒中患者中,SIRI升高与缺血性脑卒中复发风险增加有关。

Abstract:

Background

Systemic inflammatory response index (SIRI) is an emerging biomarker associated with ischemic stroke (IS) , but its correlation with recurrent IS remains unclear.

Objective

To investigate the correlation between SIRI and one-year recurrence of IS.

Methods

Patients diagnosed with IS and hospitalized in the First Affiliated Hospital of Nanchang University, the Second Affiliated Hospital of Nanchang University, the Second Hospital of Nanchang, and the Third Hospital of Nanchang between March 2019 and March 2021 were enrolled into the cohort. All patients were followed up for one year. Relevant clinical information within 48 hours of admission was collected. The recurrence of IS was recorded during the 1-year follow-up. The correlation between SIRI and one-year recurrence of IS was examined using Cox regression model, restricted cubic splines (RCS) , and subgroup analysis.

Results

A total of 1 023 eligible patients were enrolled in the cohort, including 107 (10.46%) experiencing a recurrence of IS during the one-year follow-up period. After adjusting for confounders, multivariable Cox regression analysis showed that an elevated SIRI was a risk factor for IS recurrence (HR=1.06, 95%CI=1.01-1.10, P<0.05) . Categorized into quartiles, patients in the highest quartile (fourth quartile, Q4 subgroup, n=256) of SIRI exhibited a significantly higher risk of IS recurrence compared to those in the lowest quartile (first quartile, Q1 subgroup, n=256) (HR=1.80, 95%CI=1.08-3.00, P<0.05) . RCS analysis demonstrated a J-shaped dose-response relationship between SIRI and the risk of IS recurrence (PNonlinear=0.025) . Subgroup analyses stratified by gender, age, history of stroke, and the National Institutes of Health Stroke Scale (NIHSS) score at admission were performed. A significant correlation was identified between SIRI and NIHSS score (P<0.001) . Specifically, for patients with an NIHSS score of 0-1 point, an elevated SIRI was significantly correlated with an increased risk of IS recurrence (HR=1.25, 95%CI=1.04-1.51, P=0.020) . For those with an NIHSS score of 5-15 points, an elevated SIRI was significantly correlated with a higher recurrence risk (HR=1.20, 95%CI=1.12-1.28, P<0.001) . It was indicated that a higher SIRI was significantly correlated with an increased risk of IS recurrence within these score ranges.

Conclusion

A higher SIRI is significantly correlated with an increased risk of IS recurrence. A J-shaped association is observed between SIRI and IS recurrence risk. Notably, in IS patients with NIHSS scores of 0-1 and 5-15, elevated SIRI is significantly correlated with an increased risk of recurrence.
