Abstract

Neonatal hypoxic ischemic encephalopathy (HIE) is a devastating condition resulting from a sustained lack of oxygen during birth. The interest in identifying a relevant biomarker of HIE has thrown into limelight the role of protein S100B as a clinical diagnostic marker of hypoxic brain damage in neonates. To evaluate the diagnostic value of protein S100B, measured in umbilical cord blood immediately after birth, as a useful biomarker in the diagnosis of HIE Sarnat stages II-III as well as a marker for long-term mortality and morbidity. Protein S100B was analyzed in cord blood sampled at birth from 13 newborns later diagnosed with stage II-III HIE and compared with 21 healthy controls. S100B concentrations were related to cord artery pH, amplitude-integrated electroencephalography (aEEG), stage of HIE, and death/sequelae up to an age of 6 years. Both parametric and non-parametric statistics were used with a two-sided P < 0.05 considered significant. The difference in S100B concentration was marginally statistically significant between HIE cases and controls ( P = 0.056). Cord blood acidosis ( P = 0.046), aEEG pattern severity ( P = 0.030), HIE severity ( P = 0.027), and condition at 6-year follow-up (healthy/permanent sequelae/death; P = 0.027) were all related to an increase in S100B concentration. Protein S100B in neonates suffering from HIE stages II-III appeared elevated in umbilical cord blood at birth. The S100B concentrations were positively associated to the severity of disease and the risk of suffering from neurodevelopmental sequelae and even death. • Original study involving 13 neonates affected by hypoxic-ischemic encephalopathy (HIE) compared to 21 healthy controls • Comparison of protein S100B sampled from umbilical cord blood at birth • Investigation of S100B in relation to severity of disease and long-term mortality and morbidity • S100B was found to be elevated in neonates suffering from HIE stages II-III • Elevated S100B was related to the risk of suffering from neurodevelopmental sequelae or death later in life

  • In a small series of severely asphyxiated newborns (N=13 with HIE stages 2 and 3, follow-up to age 6-7 years) compared with healthy controls (N=21), the authors found that S100B concentration was related to the severity of encephalopathy and the risk of developing permanent neurologic sequelae or death.

    “We collected cord blood immediately after birth and compared it in a small series of severely asphyxiated newborns (N¼13 with HIE stages 2 and 3, follow-up to age of 6e7 years) with that of healthy controls (N¼21) and found that the S100B concentration was related to the severity of encephalopathy and the risk of developing permanent neurologic sequelae or death.115”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
