NEJM:哌马色林对多种原因导致的痴呆性精神病有效

哌马色林对多种疾病导致的痴呆相关性精神病有良好的治疗效果

临床上可导致痴呆的疾病很多,如阿尔茨海默病、Lewy体痴呆、帕金森病、血管性痴呆和额颞叶痴呆等,可能导致患者出现幻觉和妄想等症状。与痴呆相关的精神病综合征会导致患者行为障碍,降低生活质量,增加护理人员负担。典型和非典型抗精神病药物可标签外应用于痴呆患者精神病症状,短期疗效较为明显,但长期使用可能与患者认知能力恶化、锥体外作用、镇静、跌倒和代谢异常不良事件相关。哌马色林(Pimavanserin)是选择性、非多巴胺能、5-羟色胺2A受体激动剂,在减轻帕金森病精神症状方面效果显著,2016年获FDA批准上市。近日研究人员考察了哌马色林对多种原因痴呆患者精神症状的影响。

因阿尔茨海默病、Lewy体痴呆、帕金森病、血管性痴呆和额颞叶痴呆等疾病导致精神症状的患者参与研究,所有患者先接受12周的哌马色林开放治疗,其中SAPS-H+D评分下降至少30%以及CGI-I得分1或2的患者随机继续进行哌马色林治疗或安慰剂,直至26周。研究的主要终点为精神病复发,定义为SAPS-H+D得分增加30%以及CGI-I得分6或7,痴呆相关精神病住院,因疗效原因终止或使用其他抗精神病药物。

392名患者参与开放治疗,41人因无效退出,剩余351名患者进行后续试验,其中217人(61.8%)病情控制稳定,其中哌马色林组105人,安慰剂组112人。哌马色林组12人出现精神病复发(13%),而安慰剂组28人(28%),复发风险比为0.35。在后续研究期间,哌马色林组41.0%的患者出现不良事件,而安慰剂组不良事件率为36.6%,哌马色林组最常见的不良事件包括头痛、便秘、尿路感染和无症状QT延长。
