JNNP : 帕金森病患者接受丘脑下部刺激后, 短期冲动和强迫行为的预测因素

2021-10-03 Freeman MedSci原创

术前ICB严重程度较高、术前DA剂量较低的患者的ICB结果较好,而基线注意/记忆障碍较严重的患者,结果较差。

丘脑下核(STN)深部脑刺激(DBS),是晚期帕金森病(PD)患者的一种成熟的治疗方法,可改善生活质量、运动和非运动症状(NMS)。

具体来说,STN-DBS可以影响神经精神症状,如抑郁症、焦虑症、孤独症、冲动性和强迫性。目前关于DBS对冲动和强迫行为(ICB)影响的数据是对比鲜明的,有很多方法上的异质性。

据报道,PD中ICB的主要风险因素之一是多巴胺替代疗法,特别是多巴胺激动剂(DA),这可能与间叶多巴胺能系统的过度刺激有关。

由于STN-DBS通常会导致多巴胺能药物的明显减少,即降低左旋多巴等效日剂量(LEDD),所以术后ICB的改善已被观察到。然而,研究表明,STN-DBS对ICB的影响是复杂的,超越了LEDD的减少,可能的增加因素包括术前的临床方面。了解导致ICB变化的因素对于改善DBS的病人选择至关重要。


藉此, KCL的 Anna Sauerbier等人,探究了STN-DBS对ICB影响的临床预测因素。并假设,较高的术前ICB和LEDD-DA将是术后ICB有益变化的预测因素。

在这项前瞻性、开放标签、多中心的研究中,他们对接受双侧STN-DBS的PD患者进行了术前和术后6个月随访的评估。

临床量表包括PD冲动-强迫性疾病问卷-评分表(QUIP-RS)、PD问卷、非运动症状量表(NMSS)、统一PD评分表,此外还有左旋多巴当量日剂量总表(LEDD-total)和多巴胺激动剂(LEDD-DA)。随访时的变化用Wilcoxon符号秩检验进行分析,并对多重比较进行校正(Bonferroni法)。并使用相关性和线性回归探讨了QUIP-RS变化的预测因素。最后,他们将患者分为 "QUIP-RS改善或恶化 "两类,并分析组间差异。

他们纳入了55名患者,年龄为61.7岁±8.4岁,PD病程为9.8年±4.6年。QUIP-RS临界值和精神评估确定了术前ICB的患者。在患有ICB的患者中,QUIP-RS明显改善。

然而,他们观察到临床相关的QUIP-RS结果有相当大的个体差异,因为27.3%的患者病情恶化,29.1%的患者病情改善。

在post-hoc分析中,较高的基线QUIP-RS和较低的基线LEDD-DA与较大的QUIP-RS改善有关。此外,"QUIP-RS恶化 "组在NMSS注意/记忆领域有更严重的基线损伤。

这个研究的核心结论是:术前ICB严重程度较高、术前DA剂量较低的患者的ICB结果较好,而基线注意/记忆障碍较严重的患者的结果较差。这些发现强调了对接受STN-DBS的病人进行全面的非运动和运动症状评估的必要性。
