Neurology:左旋多巴在肌张力障碍中的应用

2017-04-19 zhangfan MedSci原创

研究者认为应该改变对所有早发性肌张力障碍患者都使用左旋多巴治疗的临床原则,采用更为理性个性化的治疗手段

"每一个表现出肌张力障碍的孩子都应进行左旋多巴的试验性治疗,以免错过了对左旋多巴有效的肌张力障碍(DRD)患儿"这是源于上世纪80年代是高度保守的运动障碍治疗原则。近日研究人员对该原则进行了重新审视。

目前发现DRD患病占总肌张力障碍患者的比例较低、左旋多巴临床剂量的个体差异大、试用治疗效果不确定性大,特别是病因和病理生理学进展以及诊断手段的进步,不应当继续沿用上世纪80年代的肌张力障碍治疗原则。研究者认为在有相应条件的地区,只有在通过基因或黑质纹状体变性等方法确证多巴胺生物合成缺陷后,才建议患者使用左旋多巴。通过文献研究发现,左旋多巴偶尔对确诊的非DRD患者也有效,这反而会延误这些特殊肌张力障碍患者的治疗。

总之,研究者认为应该改变对所有早发性肌张力障碍患者都使用左旋多巴治疗的临床原则,采用更为理性个性化的治疗手段。
