Brain white matter hyperintensities can be divided into periventricular hyperintensity (PVH) and deep-and-subcortical white matter hyperintensity (DSWMH); the former contributes more to cognitive dysfunction and infarction risk. We conducted the present investigation to define the relationship between PVH and DSWMH.
Cross-sectional study.
University hospital.
We prospectively enrolled 228 healthy Japanese volunteers with relative risk values (RRVs) >0.5.
We investigated whether it is possible to use the RRV to predict PVH and DSWMH.
Among 228 volunteers, 103 (45.1%) and 157 (68.8%) exhibited PVH and DSWMH, respectively. Age, body mass index and PVH were significant independent determinants of RRV. A significant OR for PVH was noted in the highest RRV tertile compared with the lowest, after adjusting for potential confounding factors. A significant OR for high predicted PVH risk was found for RRV levels as well.
Elevated RRV levels were significantly associated with increased predicted PVH, suggesting that measuring the plasma protein-conjugated acrolein, interleukin 6 and C reactive protein levels may be useful for identifying Japanese at high risk for PVH.
脑白质高信号可分为脑室周围高信号(PVH)和深部及皮质下白质高信号(DSWMH);前者对认知功能障碍和梗死风险的影响更大。我们开展本研究以明确PVH与DSWMH之间的关系。
横断面研究。
大学医院。
我们前瞻性纳入了228名相对风险值(RRV)>0.5的健康日本志愿者。
我们研究了是否可用RRV预测PVH和DSWMH。
在228名志愿者中,分别有103名(45.1%)和157名(68.8%)出现PVH和DSWMH。年龄、体重指数和PVH是RRV的显著独立决定因素。在调整潜在混杂因素后,与最低RRV三分位数相比,最高RRV三分位数中PVH的优势比显著。RRV水平也与预测的高PVH风险的显著优势比相关。
RRV水平升高与预测的PVH增加显著相关,提示检测血浆蛋白结合丙烯醛、白细胞介素6和C反应蛋白水平可能有助于识别PVH高危的日本人。
