Official title
Evaluating Correlation Ccrd Blood IL 6 and Neonatal Outcome and CTG Inflammatory Pattern
Overview
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.
Interventions
- Other blood sampling
The study involves the collection of an additional aliquot of cord blood and an additional aliquot of maternal venous blood.
Primary outcome measures
- fetal and maternal IL6 levels [Time frame: 1 day]
Secondary outcome measures (2)
- IL6 and neonatal outcome [Time frame: 15 days]
- IL6 and histopathology [Time frame: 1 month]
