The relationship between amniotic and newborn gastric fluid inflammatory mediators

Area of Science:

• Perinatal Medicine
• Neonatology
• Immunology

Background:

• Inflammatory mediators play a crucial role in perinatal complications.
• Understanding the transfer and correlation of inflammatory markers between mother and premature neonate is vital for clinical management.

Purpose of the Study:

• To investigate the association between inflammatory mediator concentrations in maternal amniotic fluid (AF) and premature newborns' gastric fluid (GF).

Main Methods:

• Analyzed AF and GF samples from 23 mother-premature newborn dyads (<35 weeks gestation) born via Cesarean section.
• Quantified concentrations of interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-alpha (TNF-α), and mannose-binding lectin (MBL).
• Correlated mediator levels between maternal AF and neonatal GF.

Main Results:

• Significant correlations were observed between AF and GF levels for IL-6, IL-8, TNF-α, and MBL (p < 0.001 for all).
• Higher AF IL-6, TNF-α, and GF IL-8 were noted in dyads with funisitis compared to those without.
• Correlation coefficients (r) ranged from 0.768 to 0.872, indicating strong associations.

Conclusions:

• Neonatal gastric fluid inflammatory mediator levels post-birth are strongly associated with maternal amniotic fluid levels.
• This suggests a potential shared inflammatory environment or transfer mechanism between mother and fetus in premature births.
