Summary
Serum neuron-specific enolase (NSE) levels are higher in neonates than adults and decrease with age. Neonatal NSE levels depend on gestational and birth ages, necessitating age-specific reference values.
Area of Science:
- Biochemistry
- Neonatal Physiology
- Biomarker Research
Context:
- Neuron-specific enolase (NSE) is a biomarker for neuronal injury.
- Establishing normal reference ranges for neonatal biomarkers is crucial for clinical assessment.
- Postnatal development influences serum biomarker levels in newborns.
Purpose:
- To investigate the postnatal changes in serum neuron-specific enolase (NSE) levels in term and preterm neonates.
- To compare neonatal serum NSE levels with those of healthy adults.
- To determine the influence of gestational and birth age on serum NSE levels.
Summary:
- Serum NSE levels in term and preterm neonates decrease with increasing postnatal age.
- Neonatal serum NSE levels on days 1, 3, and 7 are significantly higher than in healthy adults.
- Early preterm infants exhibit higher serum NSE levels compared to full-term infants.
Impact:
- Neonatal serum NSE levels are influenced by gestational and birth ages.
- Current adult reference values for NSE are not suitable for neonates.
- Age-specific reference ranges are recommended for accurate interpretation of neonatal serum NSE levels.
