JAMA Neurol:Tau-PET可预测临床前以及AD前驱期预后

2021-10-30 MedSci原创 MedSci原创

Tau-PET已被证明对痴呆的鉴别诊断有用,但它们在预测认知变化方面的效用尚不清楚。基于此,本研究纳入8个队列共计1431名被试,平均随访时间为1.9(0.8)年。其中673例Aβ+认知功能未受损被试

阿尔兹海默症典型的病理特征是淀粉样蛋白沉积和磷酸化tau蛋白浓度升高,磷酸酶的作用导致 tau 蛋白过磷酸化,进而从微管上脱落,聚集形成了神经纤维缠结,这一过程破坏了神经元微管结构,阻碍了轴突运转,损害突触功能,同时伴有大脑的萎缩,最终导致多领域认知能力的下降损伤。

PET的示踪剂与AD患者在脑内形成的Tau蛋白聚集物有很好的亲和力,且通过tau-PET观察到的tau蛋白的沉积模式与程度与Aβ沉积、脑萎缩和低代谢影响的区域重叠度较高,并与多种认知功能的认知下降相关。

Ossenkoppele R等开展了一项多中心纵向研究,检验[18F]flortaucipir和[18F]RO948 tau PET在1431名AD痴呆、轻度认知障碍(MCI)或正常认知患者中的预后价值;将tau PET与已建立的MRI和Aβ-PET标记物进行对比,以预测未来的认知变化;并研究年龄、性别、Apoe基因型是否随时间改变基线Tau-PET与认知变化之间的关联。该研究成果发表在JAMA Neurol杂志。

该研究纳入8个队列共计1431名被试,平均随访时间为1.9(0.8)年。其中673例Aβ+认知功能未受损被试,443例Aβ+MCI患者,315例Aβ+ AD痴呆患者。这些被试共分为两个组,包括发现组(1135名被试)和验证组(296名被试)。该研究采用混合线性模型分别基于基线Aβ-PET、皮质厚度以及Tau-PET 来预测MMSE的纵向变化。

在所有参与者中以及Aβ+MCI,Aβ+CU以及Aβ-CU中,与MRI相比,Tau-PET可以更好的预测MMSE地下降。2:在Aβ+AD以及Aβ-MCI中,MRI可以更好地预测MMSE地下降。在验证队列中也发现了类似的结果,只有一个不一样的是在Aβ+AD中,tau-PET的预测效果优于MRI。

相较于皮质厚度和Aβ-PET,Tau-PET可以更好地预测MMSE地纵向变化。

在所有参与者中以及各个亚组中,与Amyloid-PET相比,Tau-PET均可以更好的预测MMSE地下降。

采用中介分析探究基线Tau-PET和认知变化之间的关联是否由基线皮质厚度介导,发现在AD痴呆组以及Aβ+MCI组,皮质厚度介导了Tau-PET和MMSE的关系。

 

采用线性混合模型探究年龄、性别、APOE基因型是否影响了基线Tau-PET和MMSE变化的关系,发现年龄改变了基线Tau-PET和MMSE改变的关系,表现为老年人在相似的Tau-PET水平下,表现出更快的认知下降。

这项多中心纵向研究中发现Tau-PET对于认知的预测有较好的预后作用,特别是在Aβ阳性MCI和Aβ阳性CU组,优于MRI和Aβ-PET,Tau-PET可能是预测临床前以及AD前驱期个体认知轨迹变化的理想的生物标志物。
