PRIMARY OBJECTIVE: To determine the relationship of serum S-100B and C-tau levels to long-term outcome after mild traumatic brain injury (mild TBI). RESEARCH DESIGN: A prospective study of 35 mild TBI subjects presenting to the emergency department. METHODS AND PROCEDURES: Six hour serum S-100B and C-tau levels compared to 3-month Rivermead Post Concussion Questionnaire (RPCQ) scores and post-concussive syndrome (PCS). MAIN OUTCOMES AND RESULTS: The linear correlation between marker levels and RPCQ scores was weak (S-100B: r = 0.071, C-tau: r = -0.21). There was no statistically significant correlation between marker levels and 3-month PCS (S-100B: AUC = 0.589, 95%CI. 038, 0.80; C-tau: AUC = 0.634, 95%CI 0.43, 0.84). The sensitivity of these markers ranged from 43.8-56.3% and the specificity from 35.7-71.4%. CONCLUSIONS: Initial serum S-100B and C-tau levels appear to be poor predictors of 3-month outcome after mild TBI.
