Mayo Clin Proc:肉毒毒素能否改善帕金森病震颤和患者感觉?

2017-10-17 王淳 环球医学

2017年9月,发表在《Mayo Clin Proc》上的一项双盲、安慰剂-对照、交叉试验,调查了肉毒毒素对帕金森病(PD)震颤的治疗效果。试验结果表明:在临床范围内,经个性化方式注射肉毒毒素(IncoA)能改善PD震颤和患者感觉,手无力发生率显着较低。

2017年9月,发表在《Mayo Clin Proc》上的一项双盲、安慰剂-对照、交叉试验,调查了肉毒毒素对帕金森病(PD)震颤的治疗效果。试验结果表明:在临床范围内,经个性化方式注射肉毒毒素(IncoA)能改善PD震颤和患者感觉,手无力发生率显着较低。

背景:在原发性震颤和PD震颤中,以固定注射给予IncoA改善震颤,但许多患者(30%-70%)会出现中度至重度无力,限制了肉毒素A在临床实践中的使用。

目的:评估IncoA注射治疗PD震颤的安全性和有效性。

患者和方法:在这项双盲、安慰剂-对照、交叉试验中,30名患者使用个性化方案每人在手和前臂接受7-12(平均值,9)次IncoA注射。本研究是在2012年6月1日至2015年6月30日间开展的,对受试者随访24周。通过统一的帕金森疾病等级评分的震颤子集以及在2组治疗后4周和8周时患者总体感觉改善情况评估治疗效果。采用测力计评估手力。

结果:IncoA注射后4周和8周时静止性震颤和震颤强度的临床等级评分的改善以及8周时活性/姿势性震颤具有统计学意义。IncoA组在4周和8周时患者感觉改善具有显着意义。4周时,2组间的握力差异没有统计学意义。

结论:在临床范围内,经个性化方式注射IncoA能改善PD震颤和患者感觉,手无力发生率显着较低。
