Περίληψη:
Background: Neonatal brain injury (NBI) is a serious adverse outcome in premature neonates. We sought to determine the levels and prognostic value of serum S100B during the first three days of life in premature neonates (<34 weeks) that later developed NBI in the form of either intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL). Methods: This is a prospective case – control longitudinal study. Each case (n = 29) was matched according to birthweight and gestational age to one neonate with normal head ultrasound scans. Results: Neonates with NBI, had significantly higher S100B concentration during the first three days of life. In both groups S100B was significantly higher on the first day when compared to the next two days of life showing a downwards trend. Serum S100B on the first day was the best predictor for adverse neonatal outcome such as death or II–IV IVH grade. A cut-off value of 10.51 ng/ml serum S100B performed a sensitivity of 100% and a specificity of 93.9% to predict adverse neonatal outcome. Conclusion: Further research on the predictive value of serum S100B regarding NBI in premature neonates is of great interest and may provide the first clinically useful biomarker for early detection of neonates at high risk. © 2020 Elsevier B.V.
