我们的目的是确定轴突损伤的生物标志物,血清切割-tau(C-tau),预测轻度创伤性脑损伤(mTBI)后的成人PCS。从急诊科获得的血液中测量C-tau。使用Rivermead脑震荡后症状问卷(RPQ)和急性医学结局SF-36 v2 ™健康调查(SF-36)在损伤后3个月评估结局。在50例患者中,有15例患者的C-tau水平可检测,10例患者的初始头部CT结果异常,22例患者有PCS。三分之一的可检测到C-tau的患者和14.3%的不可检测到C-tau的患者在头部CT上有异常结果(p=0.143)。在PCS患者中,血清C-tau的检测频率并不比没有PCS的患者高,无论是所有患者(p=0.115)还是头部CT扫描阴性的亚组(p=0.253)。无论头部CT扫描结果如何,C-tau都是mTBI后PCS的不良预测因子。
Our objective was to determine if the biomarker for axonal injury, serum cleaved-tau (C-tau), predicts PCS in adults after mild traumatic brain injury (mTBI). C-tau was measured from blood obtained in the emergency department. Outcome was assessed at three months post-injury using the Rivermead Postconcussion Symptoms Questionnaire (RPQ) and Acute Medical Outcomes SF-36v2™ Health Survey (SF-36). Out of 50 patients, there were 15 patients with detectable levels of C-tau, 10 patients with abnormal findings on initial head CT and 22 patients with PCS. One-third of patients with detectable C-tau and 14.3% of patients without detectable C-tau had abnormal findings on head CT (p=0.143). Serum C-tau was not detected more frequently in patients with PCS than those without, neither for all patients (p=0.115) nor the subgroup with negative head CT scans (p=0.253). C-tau is a poor predictor of PCS after mTBI regardless of head CT scan result.
