Summary

Intrauterine infection, or chorioamnionitis, is linked to preterm birth and serious infant health issues, including neurological impairments and increased cerebral palsy risk. Further research is needed to understand the underlying infectious and immune mechanisms.

Area of Science:

  • Obstetrics and Gynecology
  • Neonatology
  • Immunology

Background:

  • Chorioamnionitis is strongly correlated with preterm delivery before 30 weeks of gestation.
  • Intrauterine infection is associated with significant neonatal morbidity, mortality, and neurological impairments in preterm infants.

Purpose of the Study:

  • To review the established and potential consequences of intrauterine infection on neonatal outcomes.
  • To highlight the incomplete understanding of infectious/inflammatory mechanisms and host immune responses in chorioamnionitis.

Main Methods:

  • Review of existing literature on chorioamnionitis and its effects on preterm and full-term infants.
  • Analysis of associations between intrauterine infection markers and neonatal health outcomes.

Main Results:

  • Proxies of intrauterine infection link to acute neonatal morbidity, mortality, neurological impairments (e.g., cerebral palsy), chronic lung disease, and thymic involution.
  • Full-term infants exposed to intrauterine infection face increased risks of neonatal encephalopathy and cerebral palsy.

Conclusions:

  • Chorioamnionitis poses significant risks for both preterm and full-term infants, impacting neurological development and survival.
  • Further characterization of causative microbes and host immune responses is crucial for understanding and mitigating these effects.
