Towards improved neonatal outcome: future strategies

Area of Science:

• Obstetrics and Gynecology
• Neonatal Health
• Genetics and Genomics

Background:

• Maternal and fetal infections/inflammation are significant contributors to neonatal mortality and morbidity.
• Current predictive studies for preterm birth (PTB) primarily focus on high-risk phenotypes.
• Existing antenatal care strategies have not achieved primary prevention of PTB.

Purpose of the Study:

• To explore the genetic susceptibility of preterm birth (PTB).
• To investigate the combined influence of environmental/lifestyle factors and genotype on PTB causation.
• To evaluate the efficacy of current predictive markers and secondary prevention strategies for PTB.

Main Methods:

• Analysis of genetic susceptibility in relation to PTB.
• Integration of environmental and lifestyle risk factors with known genotypes.
• Review of predictive technical markers (e.g., fibronectin, cervical length, uterine activity).
• Assessment of secondary prevention methods including tocolytics and antibiotics.

Main Results:

• Predictive technical markers for PTB remain largely unproven.
• Tocolytics offer minimal benefit and should not prolong infected preterm pregnancies.
• Antibiotics in preterm premature rupture of membranes can prolong pregnancy and reduce neonatal morbidity.

Conclusions:

• A comprehensive understanding of PTB causation requires integrating genetic, environmental, and lifestyle factors.
• Current antenatal care and predictive markers are insufficient for primary PTB prevention.
• Anti-inflammatory therapies targeting intra-amniotic inflammation show promise for future treatment options.
