This study was conducted to investigate the association of diabetic peripheral neuropathy (DPN) with both arterial stiffness and intima-media thickness (IMT).
We conducted a cross-sectional analysis of 731 subjects with type 2 diabetes. DPN was diagnosed on the basis of neuropathic symptoms, insensitivity to a 10-g monofilament, abnormal pin-prick sensation, and abnormal current perception threshold. Arterial stiffness was assessed by cardio-ankle vascular index (CAVI), and IMT was assessed by B-mode ultrasonography.
Patients with DPN had higher CAVI than those without DPN in multivariate-adjusted models, whereas no differences in IMT were observed between patients with and without DPN after adjustment for age and sex. In the multivariate analysis, CAVI was a significant determinant of DPN (odds ratio 1.36 [95% CI 1.13-1.65], P = 0.001).
DPN is significantly associated with arterial stiffness without carotid intimal changes in patients with type 2 diabetes.
本研究旨在探讨糖尿病周围神经病变(DPN)与动脉僵硬度和内膜中层厚度(IMT)的关系。
我们对 731 例 2 型糖尿病患者进行了横断面分析。DPN 的诊断基于神经病变症状、10g 单丝感觉丧失、异常刺痛感和异常电流感知阈值。通过心血管踝血管指数(CAVI)评估动脉僵硬度,通过 B 型超声评估 IMT。
在多变量调整模型中,患有 DPN 的患者的 CAVI 高于没有 DPN 的患者,而在调整年龄和性别后,患有和不患有 DPN 的患者之间的 IMT 没有差异。在多变量分析中,CAVI 是 DPN 的一个显著决定因素(比值比 1.36 [95%CI 1.13-1.65],P = 0.001)。
在 2 型糖尿病患者中,DPN 与动脉僵硬度显著相关,而与颈动脉内膜变化无关。
