Preterm birth: Inflammation, fetal injury and treatment strategies

Area of Science:

• Reproductive Medicine
• Neonatal Health
• Inflammatory Biology

Background:

• Preterm birth (PTB) is a global health concern, causing significant childhood mortality and long-term complications like cerebral palsy.
• Spontaneous PTB is frequently associated with intrauterine infection and inflammation, impacting fetal development.
• Inflammatory mediators in utero can lead to fetal injury, particularly affecting the brain and lungs.

Purpose of the Study:

• To review the role of inflammation in both term and preterm birth.
• To examine the impact of intrauterine infection/inflammation on fetal development.
• To discuss current and emerging strategies for targeting and preventing PTB.

Main Methods:

• Literature review focusing on the relationship between inflammation, infection, and preterm birth.
• Analysis of studies investigating fetal injury mechanisms related to intrauterine inflammation.
• Synthesis of recent research on therapeutic and preventative strategies for PTB.

Main Results:

• Inflammation plays a critical role in the pathophysiology of spontaneous preterm birth.
• Intrauterine infection and inflammation are linked to adverse fetal outcomes, including neurological and respiratory damage.
• Current strategies for PTB prevention and treatment are limited, highlighting the need for further research.

Conclusions:

• Understanding the inflammatory pathways in PTB is crucial for developing effective interventions.
• Targeting intrauterine inflammation may offer a promising approach to reduce PTB and associated fetal injuries.
• Urgent research is needed to develop novel methods for PTB prevention, treatment, and mitigation of fetal harm.
