先前对成人和小鼠的研究表明 ADAMTS13(一种具有 1 型血小板反应蛋白基序的解整合素和金属蛋白酶,成员 13),也称为冯维勒布兰德因子 (VWF) 裂解蛋白酶,是中风的保护因子。在这里,我们在一项频率匹配的病例对照研究中对 208 名动脉缺血性中风 (AIS) 儿科患者和 125 名基于人群的对照儿童进行了 ADAMTS13 的研究。比较了 ADAMTS13 活性水平低于和高于第 10 个百分位的患者/对照的比例。此外,在五分位数比较中,将 ADAMTS13 最低五分位数中的患者与对照的比例与第二至第五五分位数中的患者与对照比例进行比较。对 VWF 抗原 (VWF:Ag)、因子 VIII 活性 (FVIII:C)、血型和年龄进行调整。 208 名患者中有 46 名 (22%) 显示 ADAMTS13 水平低于第 10 个百分位,而 125 名对照中有 5 名 (4%;p < 0.001)。调整 VWF:Ag、FVIII:C、血型和年龄后,最低百分位的比值比/95% 置信区间为 7.30/2.73–19.50,五分位数比较的比值比/95% 置信区间为 2.44/1.15–5.16。比较不同中风亚型(未确定的、心源性栓塞性、狭窄闭塞性动脉病)中 ADAMTS13 活性低于第 10 个百分位数的患者比例,未发现统计学上的显着差异(未确定,89 例中有 16 例;心源性栓塞,40 例中有 6 例;狭窄闭塞性动脉病,79 例中有 24 例;p = 0.08)。 ADAMTS13 水平在不同卒中亚型之间没有显着差异 (p = 0.29)。我们的研究结果表明 ADAMTS13 活性降低是儿科 AIS 的危险因素,并支持 ADAMTS13 在儿科 AIS 发病机制中发挥作用的概念。
Previous studies in adults and mice have implicated ADAMTS13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13), also known as von Willebrand factor (VWF)-cleaving protease, as a protective factor for stroke. Here we investigated ADAMTS13 in 208 pediatric patients with arterial ischemic stroke (AIS) and 125 population-based control children in a frequency-matched case–control study. The proportion of patients/controls with ADAMTS13 activity levels below and above the 10th percentile was compared. Additionally, in a quintile comparison, the proportion of patients versus controls in the lowest ADAMTS13 quintile was compared to those in the 2nd to 5th quintiles. Adjustment was performed for VWF antigen (VWF:Ag), factor VIII activity (FVIII:C), blood group, and age. Forty-six of 208 patients (22%) showed ADAMTS13 levels below the 10th percentile, compared with 5 of 125 controls (4%; p < 0.001). Odds ratios/95% confidence intervals were 7.30/2.73–19.50 for the lowest percentile and 2.44/1.15–5.16 in the quintile comparison after adjustment for VWF:Ag, FVIII:C, blood group, and age. Comparing the proportion of patients with ADAMTS13 activity below the 10th percentile within the different stroke subtypes (undetermined, cardioembolic, steno-occlusive arteriopathies), no statistically significant differences were found (undetermined, 16 of 89; cardioembolic, 6 of 40; steno-occlusive arteriopathies, 24 of 79; p = 0.08). ADAMTS13 levels did not significantly differ among stroke subtypes (p = 0.29). Our findings implicate reduced ADAMTS13 activity as a risk factor for pediatric AIS, and support the concept that ADAMTS13 has a role in the pathogenesis of pediatric AIS.
