Study summary

The goal of this observational study or clinical trial is to evaluate interleukin-6 (IL-6) and lactate levels in maternal and cord blood to identify early signs of fetal inflammation or infection.

Two groups of women with full-term pregnancies will be compared: • Case group (SOFI): women with a cardiotocograph (CTG) pattern suspicious for fetal infection/inflammation • Control group (NEFI): women with a normal cardiotocograph (CTG) pattern without signs of inflammation. The primary outcome is to evaluate whether IL-6 levels detected in the umbilical artery, alone or in combination with maternal IL-6 values, are associated with a cardiotocograph (CTG) pattern suggestive of fetal inflammation and/or a clinical picture suggestive of chorioamnionitis. Identifying a possible correlation between IL-6/lactate levels and fetal inflammatory status could facilitate more timely treatment of at-risk infants in the future, contributing to the reduction of adverse outcomes both in the neonatal period and in the long-term.

Secondary outcome are: -Comparison of fetal and maternal IL-6 levels between infants with a composite adverse outcome; - Comparison of fetal and maternal IL-6 levels in patients with and without signs of histological chorioamnionitis.

Study population

Case group - SOFI: Women in labor at term with a CTG showing criteria "Suggestive for Fetal Inflammation." Control group - NEFI: Women in labor at term with a CTG showing no inflammation/infection characteristics.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

SOFI case group:

  • Women with gestational age >37 weeks who access the delivery room of the Obstetrics and Obstetric Pathology Unit for labor.
  • Single fetus in cephalic presentation
  • Age ≥18 years
  • Presence of CTG characteristics associated with fetal inflammation/infection (fetal heart rate (fetal heart rate (FHR) >150 bpm with gestational age >40 weeks or a 10% increase in FHR, absence of cycling, fetal tachycardia >=160 bpm, variability \<5 bpm)
  • Signed form by the patient.

NEFI control group:

  • Women with gestation >37 weeks who access the delivery room of the Obstetrics and Obstetric Pathology Unit for labor.
  • Single fetus in cephalic presentation.
  • Age ≥18 years.
  • Patients with a CTG tracing that does not show features associated with fetal inflammation/infection (fetal heart rate (FHR) between 110-150 bpm, normal cycling, and normal variability between 5 and 25 bpm).
  • Patient signed informed consent form.

Exclusion criteria

Exclusion Criteria:

  • Failure to sign
  • Intrauterine fetal death
  • Congenital fetal and/or chromosomal abnormalities
  • Maternal cardiac abnormalities and/or cardiac therapy and/or therapy with a direct effect on maternal heart rate (e.g., labetalol, digoxin)
  • Twin or multiple pregnancy
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.
