目的
2
探讨中青年急性缺血性卒中患者外周免疫状态与临床预后的相关性。
方法
2
吉林大学第一医院纳入符合标准发病3 d内的急性缺血性卒中患者。采集外周血,采用流式细胞术测定淋巴细胞亚群计数,包括T细胞(CD3
+
CD19
-
)、CD4
+
T细胞(CD3
+
CD4
+
)、CD8
+
T细胞(CD3
+
CD8
+
)、B细胞(CD3
-
CD19
+
)和自然杀伤细胞(natural killer cell,NK cell)(CD3
-
CD16
+
CD56
+
),用以评估卒中后外周免疫状态。所有患者于发病后90 d进行电话随访,记录改良Rankin评分,0~1分定义为良好预后,2~6分定义为不良预后。
结果
2
研究最终共纳入223例患者,良好预后组171例,不良预后组52例。良好预后组患者外周血总T细胞计数、CD4
+
T细胞计数、CD8
+
T细胞计数显著高于不良预后组。多因素回归分析发现外周血总T细胞计数[比值比(odds ratio,OR)=1.199,95%CI=1.074~1.338,
P
=0.001]、CD4
+
T细胞计数(
OR
=1.277,95%CI=1.085~1.503,
P
=0.003)与3个月良好预后独立相关。总T细胞计数每微升增加100个细胞,获得良好预后的可能性增加19.9%,CD4
+
T细胞计数每微升增加100个细胞,获得良好预后的可能性增加27.7%。此外,在由传统指标组成的临床预测模型基础上增加总T细胞计数后,净重新分类指数和综合判别改善指数显著改善,AUC有所提高但差异无统计学意义。
结论
2
卒中后以总T和CD4
+
T计数为代表的外周免疫状态是中青年急性缺血性卒中患者预后的独立影响因素,综合考虑外周免疫状态能够提高临床预后预测的准确性。
Objective
2
To explore the association between peripheral immune status and clinical prognosis after acute ischemic stroke in young and middle-aged patients.
Methods
2
Eligible patients with acute ischemic stroke within 3 days of onset were recruited at The First Hospital of Jilin University. Peripheral blood lymphocyte subsets were counted using flow cytometry to evaluate peripheral
immune status after stroke,including T cells(CD3
+
CD19
-
),CD4
+
T cells(CD3
+
CD4
+
),CD8
+
T cells(CD3
+
CD8
+
),B cells(CD3
-
CD19
+
),and natural killer cells(CD3
-
CD16
+
CD56
+
). All patients were followed up by telephone at 90 days after stroke onset. The modified Rankin Scale was recorded. A score of 0-1 was defined as a favorable prognosis,while a score of 2-6 was defined as an unfavorable prognosis.
Results
2
A total of 223 patients were included,of whom 171 had favorable prognosis,and 52 had unfavorable prognosis. Patients with favorable prognosis had significantly higher levels of T cells,CD4
+
T cells,and CD8
+
T cells. Multivariate regression analysis revealed that the total T cell count(odds ratio,1.199[1.074-1.338],
P
=0.001) and CD4
+
T cell count(odds ratio,1.277[1.085-1.503],
P
=0.003) were independently associated with a favorable prognosis at 3 months. For every increase of 100 cells per microliter in the total T cell count,the probability of a favorable prognosis increased by 19.9%; for every increase of 100 cells per microliter in the CD4
+
T cell count,the probability increased by 27.7%. Moreover,adding the total T cell count to the clinical predictive model composed of traditional indicators significantly improved the net reclassification improvement and integrated discrimination improvement,and the AUC increased,but the difference was not statistically significant.
Conclusion
2
The peripheral immune status as indicated by total T cell and CD4
+
T cell counts after stroke is an independent predictor of prognosis in young and middle-aged patients with acute ischemic stroke. Comprehensive consideration of peripheral immune status can improve the accuracy of clinical prognosis prediction.
