Infection-Related Preterm Birth

Area of Science:

• Reproductive Immunology
• Neonatal Medicine
• Infectious Disease

Background:

• Preterm birth (PTB) is a leading cause of neonatal morbidity and mortality worldwide, frequently triggered by intraamniotic inflammation.
• Infection-related PTB involves fetal inflammatory response syndrome, leading to serious maternal and neonatal complications like sepsis and neurological impairment.

Purpose of the Study:

• To elucidate the inflammatory pathways initiating preterm birth.
• To highlight diagnostic criteria and management strategies for infection-related PTB.
• To emphasize the importance of understanding these pathways for developing preventive therapies.

Main Methods:

• Review of the molecular mechanisms of infection-induced inflammation in fetal membranes.
• Analysis of diagnostic criteria for PTB and chorioamnionitis.
• Examination of current management and preventive strategies for PTB.

Main Results:

• Inflammatory cascades, initiated by pathogen-associated molecular patterns binding to Toll-like receptors, activate cytokine transcription via NF-κB.
• Neutrophil accumulation and matrix metalloproteinase secretion compromise fetal membranes, leading to rupture.
• Prostaglandins induce uterine contractions and cervical changes, culminating in delivery.

Conclusions:

• Effective PTB management requires infection control, timely delivery based on fetal lung maturity, and optimized maternal-neonatal care.
• Current prevention focuses on inhibiting inflammation-driven myometrial contractions.
• Further understanding of these inflammatory pathways is crucial for novel therapeutic interventions against PTB.
