    Journal: World Neurosurg; 2018 Oct; 118():e534-e542. PubMed ID: 30257306.
    Abstract:
    OBJECTIVE: To analyze serum levels of S100 calcium-binding protein B (S100B), neuron-specific enolase (NSE), and interleukin (IL)-6 in pediatric patients with traumatic brain injury (TBI) and to assess their relationship with clinical outcome. METHODS: To measure biomarkers, peripheral venous blood was collected within 6 hours and 1 week after TBI. Initial Glasgow Coma Scale (GCS) scores and Glasgow Outcome Scale scores 6 months after the trauma were used to evaluate clinical outcome. RESULTS: Median serum levels of S100B (178.12 pg/mL), NSE (16.54 ng/mL), and IL-6 (15.48 pg/mL) at admission decreased significantly 1 week after TBI to 40.86 pg/mL, 5.85 ng/mL, and 8.63 pg/mL. In the group with poor GCS scores, serum S100B and NSE levels both at admission and 1 week after TBI were significantly higher than levels in the group with good GCS scores. Serum S100B and NSE levels 1 week after injury in patients with unfavorable 6-month outcomes were significantly higher than levels 1 week after injury in patients with favorable outcomes. CONCLUSIONS: Serum levels of S100B, NSE, and IL-6 decreased 1 week after injury. Serum levels of S100B and NSE at admission were related to initial GCS scores, and these levels 1 week after TBI were related to 6-month Glasgow Outcome Scale scores. Thus, serial measurements of serum S100B and NSE, but not IL-6, may help assess brain damage and clinical outcome of pediatric patients with TBI.
