血浆超敏C反应蛋白和脂蛋白(a)水平在缺血性卒中新TOAST分型诊断中的鉴别作用

目的 探讨急性缺血性卒中患者血浆超敏C反应蛋白(high-sensitive C-reactive protein,hs-CRP)和脂蛋白(a)Lipoprotein(a),Lp(a)]水平在新TOAST分型诊断中的鉴别作用.方法 分别采用免疫散色比浊法和免疫透射比浊法检测82例急性缺血性卒中患者(＜24 h)和60例健康对照者的血浆hs-CRP和Lp(a)水平,并尽可能完成动态心电图、超声心动图、MRI、磁共振血管造影/CT血管造影/数字减影血管造影等辅助检查,最后根据缺血性卒中新TOAST分型诊断标准对其进行分型.结果 急性缺血性卒中患者各亚型及对照组血浆hs-CRP和Lp(a)水平存在显著差异(P均＜0.001),其中心源性栓塞(cardioembolism,CE)患者血浆hs-CRP水平最高.hs-CRP可作为CE亚型的一个生物学标记物(优势比1.84,95%可信区间1.18～2.85;P＜0.05);当其浓度＞3.48 mg/L时,预测CE的敏感性和特异性分别为89%和83%.AT患者血浆Lp(a)水平最高,可作为AT亚型的一个生物学标记物(优势比1.02,95%可信区间1.01～1.03;P＜0.05);当其浓度＞183.5 mg/L时,其预测AT的敏感性和特异性分别达87%和85%.结论 急性缺血性卒中患者血浆hs-CRP和Lp(a)水平可为及时准确的病因学分型提供一定的帮助.

Abstract：

Objective To investigate the identification role of plasma high sensitive Creactive protein (hs-CRP) and lipoprotein (a) (Lp a]) levels in the diagnosis of patients with acute ischemic stroke according to the TOAST classification. Methods The levels of plasma hsCRP and Lp (a) in 82 acute stroke patients ( ＜24 hours) and 60 healthy controls were detected using immune scatter turbidimetry and immune transmission turbidity, and try to make use of Holter, ultrasonography, magnetic resonance imaging, magnetic resonance angiography/CT angiography/dagital subtraction angiography and other tests. Finally, they were classified according to the diagnostic criteria of the TOAST classification of ischemic stroke. Results There were significant differences in plasma hs-CRP and Lp (a) levels between all the subtypes of the acute ischemic sroke group and the control group (all P ＜0. 001). The the level of plasma hsCRP in patients with cardioembolism (CE) was highest. Hs-CRP could be used as a biological marker of CE subtype (odds ratioOR] = 1. 84,95% confidence interval CI] 1. 18-2. 85, P ＜ 0. 05). When its concentration was ＞ 3. 48 mg/L, the sensitivity and specificity of predicting CE were 89% and 83% respectively. The plasma level of the AT patients was highest, it could be used as a biological marker of AT subtype (OR = 1. 02, 95% CI 1. 01-1. 03, P＜0. 05); when its concentration was ＞ 183. 5 mg/L, the sensitivity and specificity of predicting AT were 87% and 85% respectively. Conclusions The plasma hs-CRP and Lp (a) levels of patients with acute ischemic stroke may provide some help for timely and accurate etiological typing.
