摘要:

研究显示,帕金森病(PD)的临床过程、症状表现和治疗反应方面存在性别差异。丘脑底核脑深部电刺激(STN-DBS)是一种治疗帕金森病的成熟疗法,但性别对其治疗效果的影响仍有争议。为分析丘脑底核脑深部电刺激后运动症状、非运动症状和生活质量(QOL)的性别差异,研究纳入90例帕金森病患者,55例男性和35例女性,年龄63.00±8.01岁,评估丘脑底核脑深部电刺激治疗后1个月(M1)和12个月(M12)疗效。主要结局是通过评估帕金森病统一评分量表第Ⅲ部分的总分和运动项目的分值,来衡量M1时与基线(M0)相比的运动功能变化。在术后1和12个月的随访中发现,男性和女性患者在药物关期的运动症状均明显改善,但只有男性患者在药物开期的运动功能较术前明显提高。在非运动症状方面,手术对于男性患者不宁腿综合征的改善程度要大于女性。生活质量方面,只有男性患者总体的生活质量较术前明显提高。最后,他们建立广义线性模型,探究影响疗效的性别特异性因素,发现H-Y分期与男性术后1年的运动症状的改善呈正相关,左旋多巴等效剂量与女性术后1年的运动改善呈负相关。总之,在运动症状、非运动症状和生活质量方面,女性从丘脑底核脑深部电刺激获得的益处少于男性。在每个性别中都发现了与运动改善有关的特定因素,即H-Y分期和左旋多巴等效剂量。这些发现可能有助于指导丘脑底核脑深部电刺激患者的选择、预后评估和刺激方案的制定,以获得最佳疗效。

Abstract: There are many documented sex differences in the clinical course, symptom expression profile, and treatment response of Parkinson’s disease, creating additional challenges for patient management. Although subthalamic nucleus deep brain stimulation is an established therapy for Parkinson’s disease, the effects of sex on treatment outcome are still unclear. The aim of this retrospective observational study, was to examine sex differences in motor symptoms, non-motor symptoms, and quality of life after subthalamic nucleus deep brain stimulation. Outcome measures were evaluated at 1 and 12 months post-operation in 90 patients with Parkinson’s disease undergoing subthalamic nucleus deep brain stimulation aged 63.00 ± 8.01 years (55 men and 35 women). Outcomes of clinical evaluations were compared between sexes via a Student’s t-test and within sex via a paired-sample t-test, and generalized linear models were established to identify factors associated with treatment efficacy and intensity for each sex. We found that subthalamic nucleus deep brain stimulation could improve motor symptoms in men but not women in the on-medication condition at 1 and 12 months post-operation. Restless legs syndrome was alleviated to a greater extent in men than in women. Women demonstrated poorer quality of life at baseline and achieved less improvement of quality of life than men after subthalamic nucleus deep brain stimulation. Furthermore, Hoehn-Yahr stage was positively correlated with the treatment response in men, while levodopa equivalent dose at 12 months post-operation was negatively correlated with motor improvement in women. In conclusion, women received less benefit from subthalamic nucleus deep brain stimulation than men in terms of motor symptoms, non-motor symptoms, and quality of life. We found sex-specific factors, i.e., Hoehn-Yahr stage and levodopa equivalent dose, that were related to motor improvements. These findings may help to guide subthalamic nucleus deep brain stimulation patient selection, prognosis, and stimulation programming for optimal therapeutic efficacy in Parkinson’s disease.
