Neurology:血清咖啡因和代谢物是早期帕金森病的可靠生物标志物!

2018-01-04 xing.T MedSci原创

由此可见,咖啡因和咖啡因代谢产物绝对含量低是早期帕金森病的诊断标志物。这与先前通过流行病学和实验研究揭示的咖啡因神经保护作用相一致。

近日,神经病学领域权威取杂志Neurology上发表了一篇研究文章,研究人员旨在通过液相色谱-质谱法调查帕金森病患者和对照者血清中咖啡因的动力学和代谢情况。

研究人员采用液相色谱-质谱联用法对108例帕金森病患者和31例健康成人血清中咖啡因及其11种代谢物进行检测,并采用直接测序法筛查了与咖啡因相关的基因突变。

研究人员发现早期帕金森病患者血清中咖啡因水平和9种下游代谢物显著下降,这些物质与咖啡因摄入量和疾病严重程度无关。对照者相比,在人体编码主要参与代谢咖啡因的细胞色素P450酶的基因CYP1A2或CYP2E1进行检测无显著的遗传变异。同样,伴有运动并发症的帕金森病患者的咖啡因浓度也明显低于无运动并发症的患者。疾病的严重程度与编码腺苷2A受体的ADORA2A基因的单核苷酸变异之间的关联未发现显著性,这意味着这与受体敏感性的变化和表型无关。通过受试者工作特征曲线分析,发现血清咖啡因和代谢物水平是一种潜在的诊断生物标志物。

由此可见,咖啡因和咖啡因代谢产物绝对含量低是早期帕金森病的诊断标志物。这与先前通过流行病学和实验研究揭示的咖啡因神经保护作用相一致。
