帕金森病交感神经皮肤反应的临床研究

目的 探讨交感神经皮肤反应(SSR)对帕金森病自主神经功能障碍的诊断价值.方法 对解放军第一○二医院神经内科自2006年7月至2008年8月门诊或住院的47例帕金森病患者及与之相匹配的20例健康人进行SSR检测,并对其中有自主神经功能障碍患者与无自主神经功能障碍患者的结果进行对比分析. 结果帕金森病患者与健康人相比,上肢潜伏期明显延长(1.55±0.18 vs 1.42±0.29),波幅明显降低(1.87±0.26 vs 2.56±1.47);下肢潜伏期明显延长(2.13±0.16vs 2.04±0.27),波幅明显降低(0.49±0.21 vs 0.76±0.39),差异均有统计学意义(P<0.05).有自主神经功能障碍患者与无自主神经功能障碍患者相比,上肢潜伏期明显延长(1.56 ± 0.17 vs 1.53 ± 0.15),波幅明显降低(1.75±0.21 vs 1.89±0.33);下肢潜伏期明显延长(2.17 ± 0.18 vs 2.08±0.24),波幅明显降低(0.46±0.20 vs 0.51±0.17),差异均有统计学意义(P<0.05). 结论 SSR检测结果与患者临床表现相一致,其对帕金森病患者的自主神经功能障碍有诊断价值.

Value of sympathetic skin response in assessing autonomic dysfunction in Parkinson's disease

Objective To assess the value of detecting sympathetic skin response (SSR) in the diagnosis of autonomic dysfunction in patients with Parkinson disease (PD). Methods SSR measurement was performed in 47 PD patients and 20 healthy control subjects and the results were compared. The SSR was also comparatively analyzed between patients with and those without autonomic dysfimction. Results Compared with the healthy controls, the PD patients showed significantly lowered mean amplitude (2.56±1.47 vs 1.87±0.26, P<0.05) and prolonged latency (1.42±0.29 vs 1.55± 0.18, P<0.05) of the SSR in the upper limbs, with also lowered mean amplitude (0.76±0.39 vs 0.49±0.21, P<0.05) and prolonged latency (2.04±0.27 vs 2.13±0.16, P<0.05) in the lower limbs. Compared with the PD patients without autonomic dysfunction, those having autonomic dysfunction showed significantly lowered mean amplitude (1.89±0.33 vs 1.75±0.21, P<0.05) and prolonged latency (1.53±0.15 vs 1.56±0.17, P<0.05) of SSR in the upper limbs and lowered mean amplitude (0.51±0.17 vs 0.46±0.20,P<0.05) and prolonged latency (2.08±0.24 vs 2.17±0.18, P<0.05) in the lower limbs. Conclusion The results of SSR measurements are consistent with the clinical manifestations of the PD patients. SSR can be of value in the diagnosis of autonomic nerve dysfunction in PD.
