Insights
Perinatal infection and inflammation increase neonatal brain damage risk. Sustained systemic inflammation in preterm infants is linked to worse neurodevelopmental outcomes compared to shorter inflammation periods.
Area of Science:
- Neonatal neurology
- Perinatal medicine
- Developmental neuroscience
Background:
- Perinatal infection and inflammation are known risk factors for neonatal brain damage and developmental disabilities.
- The duration and pattern of inflammatory responses in newborns are critical factors influencing neurodevelopmental outcomes.
Purpose of the Study:
- To review evidence on intermittent or sustained systemic inflammation (ISSI) in preterm newborns.
- To elucidate the role of ISSI in adverse neurodevelopmental outcomes in preterm infants.
Main Methods:
- Integrated mechanism review of existing scientific literature.
- Analysis of evidence linking perinatal inflammation patterns to neurodevelopmental trajectories.
Main Results:
- Preterm newborns can experience intermittent or sustained systemic inflammation (ISSI).
- ISSI appears to be a more significant contributor to adverse neurodevelopmental outcomes in preterm infants than shorter-duration inflammation.
Conclusions:
- The pattern and duration of systemic inflammation are crucial in determining neurodevelopmental outcomes in preterm infants.
- Targeting and managing sustained inflammation in preterm neonates may be key to preventing developmental disabilities.
Abstract:
Exposure to perinatal infection and inflammation is associated with an increased risk for neonatal brain damage and developmental disabilities. In this integrated mechanism review, we discuss evidence in support of the contention that the preterm newborn is capable of intermittent or sustained systemic inflammation (ISSI), which appears to contribute more to adverse neurodevelopmental outcomes in preterm infants than does shorter duration inflammation.
