Possible strategies to protect the preterm brain against the fetal inflammatory response
1Neuroepidemiology Unit, Children's Hospital, 300 Longwood Avenue, Boston, MA 02115, USA.
Insights
Antenatal infection can cause fetal inflammatory responses, leading to white matter damage in preterm infants. Strategies to enhance protection, modify responses, and limit damage are proposed for future interventions.
Area of Science:
- Neonatal research
- Perinatal medicine
- Neuroscience
Background:
- Antenatal infection is a known risk factor for adverse neonatal outcomes.
- Fetal inflammatory response is implicated in white matter damage in preterm infants.
- Understanding this link is crucial for developing preventative strategies.
Purpose of the Study:
- To explore potential intervention strategies to interrupt the sequence from antenatal infection to white matter damage.
- To identify approaches for enhancing endogenous protection, modifying inflammatory responses, and limiting downstream damage.
Main Methods:
- Review of accruing evidence linking antenatal infection, fetal inflammation, and white matter injury.
- Speculative analysis of potential intervention targets.
- Identification of the need for further observational and experimental studies.
Main Results:
- A fetal inflammatory response is a key mediator between antenatal infection and white matter damage in preterm neonates.
- Potential intervention strategies include enhancing endogenous protection, modifying inflammatory responses, and limiting downstream damage.
Conclusions:
- Interrupting the harmful sequence of antenatal infection-induced white matter damage in preterm infants is a critical goal.
- Enhancing protection, modifying responses, and limiting damage are promising avenues for intervention design.
- Further observational and experimental studies are essential before clinical interventions can be considered.
Abstract:
The accruing evidence that a fetal inflammatory response is the link between antenatal infection and white matter damage in the preterm newborn infant offers room for speculation how this harmful sequence could be interrupted. Enhancement of endogenous protection, response modification, and damage limitation downstream could be helpful strategies for intervention design. Appropriate observational and experimental studies are needed before clinical interventions can be initiated.
