Amniotic fluid and the extremely preterm baby's gut

Official title: The Impact of Amniotic Fluid on the Development and Microbial Colonization of the Preterm Intestinal Tract: the AMFIBIE Study

Run by Maxima Medical Center · NCT07152106 · Data updated 2026-11-12

We will see if amniotic fluid from extremely preterm births (24+0 to 27+6 weeks) shows changes that relate to gut problems such as necrotizing enterocolitis or sepsis in very preterm infants.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are obstetric patients aged 16 or older who deliver extremely preterm infants (gestational age 24+0 to 27+6 weeks) at the participating centers and can provide written informed consent.

Probably not a fit

Patients delivering outside the specified gestational age range, pregnancies with fetal congenital or chromosomal abnormalities, those unable to provide consent, or those delivering at non-participating hospitals are not expected to benefit from this project.

What this trial studies

This multicenter, prospective cohort will collect about 5 mL of amniotic fluid from 125 deliveries at gestational ages 24+0 to 27+6 weeks at Amsterdam UMC and Máxima Medical Center. Samples will be obtained during vaginal delivery or cesarean section and analyzed using advanced molecular, metabolomic, and microbiome techniques to characterize fluid composition. Secondary analyses will compare amniotic fluid profiles in cases with maternal chorioamnionitis or fetal growth restriction, examine key metabolites across gestation, and correlate amniotic fluid signatures with neonatal outcomes and early gut microbiota. No interventions are given; the project is observational and aims to identify biomarkers and biological signals linked to NEC and neonatal sepsis risk.

Why it matters

Potential benefit: If successful, the findings could identify amniotic fluid biomarkers that help predict which extremely preterm infants are at higher risk of NEC or sepsis, enabling earlier monitoring or tailored care.

How similar studies have gone: Previous research has linked amniotic fluid components to fetal gut development, but comprehensive molecular profiling in the extremely preterm population is relatively novel and not yet well established.
