摘要: 目的 探讨早发型帕金森病患者外周红细胞α-突触核蛋白水平是否存在特异性改变。方法 纳入47例早发型帕金森病患者,52例健康受试者。采集受试者外周静脉血标本并分离红细胞,用电化学发光免疫法检测红细胞中α-突触核蛋白水平。对其中25例早发型帕金森病患者进行随访,2年后再次采集静脉血标本和临床评估。结果 早发型帕金森病患者红细胞总体和聚集体形式的α-突触核蛋白水平均显著高于健康对照组[总体1.28(0.94, 2.13) vs 0.57(0.41, 0.70), P<0.001;聚集体202.18(152.16, 244.22) vs 128.40(107.61, 157.02), P<0.001]。2年随访后帕金森病患者运动功能和认知功能较基线无显著进展,而红细胞聚集体形式的α-突触核蛋白水平较基线时特异性升高[211.66(159.71, 263.73)vs 170.12(139.31, 233.42),P=0.046]。结论 外周红细胞α-突触核蛋白检测对于早发型帕金森病同样具有较好诊断价值,进一步证实上述指标是诊断帕金森病潜在的生物标志物。

Abstract: Objective To investigate whether α-synuclein levels in peripheral erythrocytes are associated with early-onset Parkinson‘s disease(PD). Methods The subjects included 47 patients with early-onset PD and 52 healthy controls.The venous blood was obtained to separate erythrocyte.  The electrochemiluminescence assay was used to measure total and oligomeric α-synuclein levels. After 2 year  25 PD patients were re-examined with repeated blood collection and clinical assessments. Results Compared with control group total and oligomeric α-synuclein levels in erythrocyte  in early-onset PD groups were significantly increased[total α-synuclein: 1.28(0.94, 2.13) vs  0.57(0.41, 0.70), P<0.001; oligomer: 202.18(152.16, 244.22) vs 128.40(107.61, 157.02), P<0.001]. In the follow-up study over 2 years, motor and cognitive scores did not process after 2-year follow-up,   but erythrocytic oligomeric α-synuclein levels in early-onset PD  were significantly increased than that at baseline [211.66(159.71, 263.73) vs 170.12(139.31, 233.42), P=0.046]. Conclusion Our study suggests that total and oligomeric α-synuclein in erythrocyte were elevated in early-onset PD and could serve as a potential diagnostic biomarker for PD and could serve as a potential diagnostic biomarker for PD.
