Study summary

Compare the bacterial digestive microbiota during the stay in neonatal intensive care between a group of premature newborns developing a NEC (necrotizing enterocolitis) and a group of newborns free from NEC.

Read the detailed description

Monitoring of a cohort of premature newborns with constitution of a collection of biological samples.

follow-up of newborns from birth up to 37 weeks of amenorrhea. The medical care of children will not be affected by their participation in the research.

  • Sampling of amniotic fluid at the time of rupture of the water bag
  • Sampling of the blood contained in the umbilical cord after clamping and section of the cord
  • Sampling of meconium during the first 24 hours of life in intensive care / neonatal / maternity ward
  • Collection of a daily stool sample until the end of hospitalization and when a NEC occurs
  • Sampling of gastric residues during an episode of NEC
  • Taking a daily sample of the newborn's enteral food
  • Sampling of 500 µL of additional blood weekly during the punctures made for the treatment
  • Daily statement of constants
  • Record of all complications related to prematurity (HIV, bronchodysplastic, sepsis)

    • Blood analysis: CBC, platelets and CRP (data analyzed as part of the treatment). Specific analyzes for research will assess: the level of tryptase, IL4 and TLR4. The samples will be stored and analyzed in the immunology laboratory of the CHU Clermont Ferrand (Pr B. Evrard)
    • Analysis of the meconium sample and each stool emitted during hospitalization, and during an episode of ECUN

  • affiliated with a social security regime
  • the holders of parental authority are able to give an to participate in the research

Exclusion criteria

Exclusion Criteria:

  • fetal pathology
  • newborns whose holders of parental authority are under guardianship or under the age of 18
  • refusal of participation by holders of parental authority
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2021 to primary completion in Aug 2024, 36 months.

Of 33 interventional studies with no phase under Enterocolitis, Necrotizing, half reached primary completion within 39 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 59. This study's 36 months is close to that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 10, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
