摘要: 目的 旨在探讨血清Aβ42与磷酸化Tau蛋白(p-Tau)检测的临床价值。 方法 收集南京大学医学院附属鼓楼医院已开展的425例门诊或住院60岁以上老年病人的血清Aβ42与p-Tau检测结果(两项均为同时检测),分析其在痴呆或其他疾病病人中的阳性率情况。 结果 血清Aβ42与p-Tau的总体阳性率分别为36.2%与24.7%, 同时阳性率为21.4%。血清Aβ42在诊断为认知功能障碍、痴呆及AD的病人中的阳性率分别为23.8%、44.9%与50.0%,血清p-Tau分别为12.4%、22.4%与16.7%。然而,它们在具有肺部炎症或感染的病人中阳性率高达64.7%,并且两者几乎同时为阳性。 结论 血清Aβ42与p-Tau水平对AD的辅助诊断价值可能有限,但对提示肺部感染可能具有临床价值。

Abstract: Objective To investigate the clinical value of serum amyloid-beta 42(Aβ42) and phosphorylated Tau (p-Tau). Methods A total of 425 elderly cases were enrolled in this study who received the measurement of Aβ42 and p-Tau at the same time. The positive rate of Aβ42 and p-Tau was analyzed in the elderly patients with dementia or other diseases. Results The overall positive rate of serum Aβ42 and p-Tau was 36.2% and 24.7% respectively, and 21.4% of the patients presented with both positive Aβ42 and p-Tau. Among the patients diagnosed as cognitive impairment, dementia and AD, the positive rate of Aβ42 was 23.8%, 44.9%, 50.0% respectively, and the positive rate of p-Tau was 12.4%, 22.4%, 16.7% respectively. However, both of them were positive in 64.7% of the patients with pulmonary infection or inflammation diseases, and they were almost positive simultaneously in a patient. Conclusions The diagnostic values of serum Aβ42 and p-Tau for AD might be limited, but they might be potential indicators of pulmonary infection or inflammation disorders.
