Neurology:雷诺嗪可改善先天性肌强直症状

2017-07-16 zhangfan MedSci原创

研究发现,雷诺嗪对于先天性肌强直患者表现出良好的耐受性和症状缓解作用。进一步的临床研究即将开展

近日研究人员开展了雷诺嗪用于改善先天性肌强直患者(MC)肌强直和肌肉僵硬症状和体征的开放标签试验研究。

研究招募了13名MC患者,分别在基线,第2, 4和5周进行了疗效评估。患者在基线服用雷诺嗪(500mg每天2次),如果耐受良好2周后增加剂量至1000mg每天2次并维持至4周。主要终点包括自我报告症状严重程度变化(僵硬、虚弱和疼痛)、计时“起立-行走”测试(TUG)、手僵硬、眼睑肌强直以及肌电图测试。

研究结果显示,患者自我报告的僵硬(p<0.0001)和虚弱(p<0.01)严重程度较基线显著下降。TUG以及手僵硬程度下降(p = 0.03, p = 0.01)。小指展肌和胫骨前肌肌电图显示治疗4周后强直持续时间显著减少。试验过程中未发生因不良事件导致的患者停药。

研究发现,雷诺嗪对于先天性肌强直患者表现出良好的耐受性和症状缓解作用。进一步的临床研究即将开展。
