BACKGROUND/PURPOSE Because atherosclerotic factors and antithrombotic agents sometimes induce cerebral microbleeds (CMBs), patients with cerebral large artery disease (CLAD) tend to have more CMBs than control subjects. On the other hand, VEGF contributes to the disruption of the blood-brain barrier, and it may induce parenchymal edema and bleeding. We conducted a study to evaluate the role of vascular endothelial growth factor (VEGF) in the occurrence of CMBs in patients with CLAD. METHODS CLAD is defined as stenosis or occlusion of either the carotid artery or the middle cerebral artery of 50% or more. We prospectively registered patients with CLAD who were hospitalized in our neurocenter. Biological backgrounds, atherosclerotic risk factors, administration of antithrombotics before hospitalization, and levels of cytokines and chemokines were evaluated. Susceptibility-weighted imaging or T2*-weighted MR angiography was used to evaluate CMBs. The Brain Observer MicroBleed Scale (BOMBS) was used for CMB assessments. Images were analyzed with regard to the presence or absence of CMBs. We also examined plasma VEGF concentrations using a commercial ELISA kit. Because more than half showed plasma VEGF levels below assay detection limits (3.2 pg/mL), the patients were dichotomized by plasma VEGF levels into two groups (above and below the detection limit). After univariate analyses, logistic regression analysis was conducted to determine the factors associated with the CMBs after adjustment for age, sex, the presence of hypertension, and administration of antithrombotic agents. A similar analysis with CMBs separated by location (cortex, subcortex, or posterior circulation) was also conducted. RESULTS Sixty-six patients (71.1 ± 8.9 years, 53 males and 13 females) were included in this study. Plasma VEGF levels were not correlated with age, sex, and atherosclerotic risk factors; however, patients with VEGF levels >3.2 pg/mL tended toward more frequent CMBs (60.0 vs. 32.6%, in the presence and absence of CMBs, p = 0.056). With regard to the location of CMBs, those in the cortex and/or at the gray-white junction were observed more frequently in the patients with VEGF levels >3.2 pg/mL after multivariable analyses (odds ratio: 3.80; 95% confidence interval: 1.07-13.5; p = 0.039). CONCLUSIONS In patients with CLAD, elevated plasma VEGF might be associated with CMBs, especially those located in the cortex and/or at the gray-white junction.

脑大动脉疾病患者血浆VEGF水平升高与脑微出血有关。

背景/目的由于动脉粥样硬化因子和抗血栓形成剂有时会诱发脑微出血(CMB),因此脑大动脉疾病(CLAD)患者的CMB往往比对照对象多。另一方面,VEGF有助于破坏血脑屏障,并可能引起实质性水肿和出血。我们进行了一项研究,以评估血管内皮生长因子(VEGF)在CLAD患者中CMB发生中的作用。方法CLAD被定义为颈动脉或大脑中动脉的狭窄或闭塞程度达到或超过50%。我们对在我们神经中枢住院的CLAD患者进行了前瞻性登记。生物学背景,动脉粥样硬化危险因素,住院前服用抗血栓药,并评估细胞因子和趋化因子的水平。使用药敏加权成像或T2 *加权MR血管造影来评估CMB。脑观察者微出血量表(BOMBS)用于CMB评估。分析关于CMB存在或不存在的图像。我们还使用商业ELISA试剂盒检查了血浆VEGF浓度。由于超过一半的患者血浆VEGF水平低于检测检出限(3.2 pg / mL),因此按血浆VEGF水平将患者分为两组(高于和低于检出限)。经过单因素分析后,进行了逻辑回归分析,确定了年龄,性别,高血压的存在和抗血栓药的使用后,与CMBs相关的因素。对CMB按位置(皮质,亚皮质,或后循环)。结果本研究共纳入66例患者(71.1±8.9岁,男53例,女13例)。血浆VEGF水平与年龄,性别和动脉粥样硬化危险因素无关。但是,VEGF水平> 3.2 pg / mL的患者倾向于更频繁的CMB(有CMB和无CMB时,分别为60.0和32.6%,p = 0.056)。关于CMB的位置,经多变量分析后,在VEGF水平> 3.2 pg / mL的患者中,皮层和/或灰白色交界处的CMB发生率更高(几率:3.80; 95%置信区间: 1.07-13.5; p = 0.039)。结论在CLAD患者中,血浆VEGF升高可能与CMB相关,尤其是位于皮质和/或灰白色交界处的CMB。结果本研究共纳入66例患者(71.1±8.9岁,男53例,女13例)。血浆VEGF水平与年龄,性别和动脉粥样硬化危险因素无关。但是,VEGF水平> 3.2 pg / mL的患者倾向于更频繁的CMB(有CMB和无CMB时,分别为60.0和32.6%,p = 0.056)。关于CMB的位置,经多变量分析后,在VEGF水平> 3.2 pg / mL的患者中,皮层和/或灰白色交界处的CMB发生率更高(几率:3.80; 95%置信区间: 1.07-13.5; p = 0.039)。结论在CLAD患者中,血浆VEGF升高可能与CMB相关,尤其是位于皮质和/或灰白色交界处的CMB。结果本研究共纳入66例患者(71.1±8.9岁,男53例,女13例)。血浆VEGF水平与年龄,性别和动脉粥样硬化危险因素无关。但是,VEGF水平> 3.2 pg / mL的患者倾向于更频繁的CMB(有CMB和无CMB时,分别为60.0和32.6%,p = 0.056)。关于CMB的位置,经多变量分析后,在VEGF水平> 3.2 pg / mL的患者中,皮层和/或灰白色交界处的CMB发生率更高(几率:3.80; 95%置信区间: 1.07-13.5; p = 0.039)。结论在CLAD患者中,血浆VEGF升高可能与CMB相关,尤其是位于皮质和/或灰白色交界处的CMB。血浆VEGF水平与年龄,性别和动脉粥样硬化危险因素无关。但是,VEGF水平> 3.2 pg / mL的患者倾向于更频繁的CMB(有CMB和无CMB时,分别为60.0和32.6%,p = 0.056)。关于CMB的位置,经多变量分析后,在VEGF水平> 3.2 pg / mL的患者中,皮层和/或灰白色交界处的CMB发生率更高(几率:3.80; 95%置信区间: 1.07-13.5; p = 0.039)。结论在CLAD患者中,血浆VEGF升高可能与CMB相关,尤其是位于皮质和/或灰白色交界处的CMB。血浆VEGF水平与年龄,性别和动脉粥样硬化危险因素无关。但是,VEGF水平> 3.2 pg / mL的患者倾向于更频繁的CMB(有CMB和无CMB时,分别为60.0和32.6%,p = 0.056)。关于CMB的位置,经多变量分析后,在VEGF水平> 3.2 pg / mL的患者中,皮层和/或灰白色交界处的CMB发生率更高(几率:3.80; 95%置信区间: 1.07-13.5; p = 0.039)。结论在CLAD患者中,血浆VEGF升高可能与CMB有关,尤其是位于皮质和/或灰白色交界处的CMB。在存在和不存在CMB的情况下,p = 0.056)。关于CMB的位置,经多变量分析后,在VEGF水平> 3.2 pg / mL的患者中,皮层和/或灰白色交界处的CMB发生率更高(几率:3.80; 95%置信区间: 1.07-13.5; p = 0.039)。结论在CLAD患者中,血浆VEGF升高可能与CMB相关,尤其是位于皮质和/或灰白色交界处的CMB。在存在和不存在CMB的情况下,p = 0.056)。关于CMB的位置,经多变量分析后,在VEGF水平> 3.2 pg / mL的患者中,皮层和/或灰白色交界处的CMB发生率更高(几率:3.80; 95%置信区间: 1.07-13.5; p = 0.039)。结论在CLAD患者中,血浆VEGF升高可能与CMB相关,尤其是位于皮质和/或灰白色交界处的CMB。
