Alz Res Therapy:胆碱酯酶抑制剂使用,或和认知功能变化无关

2021-11-07 Freeman MedSci原创

在有或没有淀粉样物质负担的患者中,使用或不使用CEI与1年的随访中的认知变化无关

胆碱酯酶抑制剂(ChEIs)是美国食品和药物管理局(FDA)批准的阿尔茨海默病(AD)的对症治疗药物,包括多奈哌齐、利福斯提明和加兰他敏。然而,它们对轻度认知障碍(MCI)的疗效并不确定。根据Petersen等人最近更新的实践指南,在MCI中使用CEI没有A级证据,建议医生可以选择不提供CEI。然而,根据阿尔茨海默病神经影像倡议(ADNI)队列的研究,44%的MCI患者接受了ChEIs治疗。

此前已经进行了相当多的研究来评估CEI治疗对MCI患者的影响。然而,参与者被纳入的依据是MCI的临床诊断,而没有AD的病理学确认。因此,这些研究人群可能包含异质性的病理,这可能导致不一致的结果。

由于缺乏针对MCI患者的经批准的药物治疗,以及对进展为痴呆的担忧,可能导致使用ChEIs,尽管没有强有力的证据证明其疗效。由于ChEIs是基于早期AD的病理变化而开发的,评估ChEIs对有AD生物标志物证实的MCI患者的影响可能为ChEI的使用提供关于开始治疗的时机或治疗的适应症的有用线索。


藉此,韩国首尔大学的的Jung-Min Pyun探究了ChEIs对MCI患者认知能力的影响及其与淀粉样病变的相互作用。

他们纳入了111名临床痴呆评分(CDR)为0.5分的MCI患者,进行了1年的随访认知评估,并在基线认知评估前后6个月内进行了淀粉样蛋白正电子发射断层扫描(PET)(73名CEI使用者和38名CEI非使用者),来自首尔国立大学盆塘医院的神经认知行为中心。

此外,那些在基线认知评估前6个月以上的淀粉样蛋白PET扫描呈阳性的患者和在1年的随访认知评估后6个月以上的淀粉样蛋白PET扫描呈阴性的患者也被纳入。

在总共111名患者中,25名CEI使用者和25名CEI非使用者通过基线迷你精神状态检查(MMSE)得分、年龄、教育水平、CDR和淀粉样蛋白PET阳性率进行倾向性评分匹配。进行多元线性回归分析以评估使用CEI和淀粉样PET阳性对1年内认知变化的影响。进行单变量和多变量逻辑回归分析,以评估在1年的随访中,使用CEI和疾病进展到CDR 1之间的关系。

他们发现:使用或不使用CEI与1年内的认知变化没有关系。淀粉样蛋白PET的阳性或阴性并没有改变这种非关联性。

此外,CDR 1的进展与基线MMSE评分低有关(OR 0.606,CI 0.381-0.873),但与使用或不使用CEI无关,也与淀粉样蛋白PET结果无关。

该研究的重要意义在于发现了:在有或没有淀粉样物质负担的患者中,使用或不使用CEI与1年的随访中的认知变化无关。此外,使用或不使用CEI不能预测1年随访时疾病进展到CDR 1。
