[Plasma fibronectin in normal pregnancy and EPH gestosis]

Area of Science:

• Biochemistry
• Obstetrics
• Maternal-fetal medicine

Context:

• Investigating plasma fibronectin concentrations in various physiological and pathological conditions related to pregnancy.
• Establishing reference ranges for fibronectin during pregnancy, postpartum, and in newborns.
• Comparing fibronectin levels in healthy pregnancies versus pregnancies complicated by EPH gestosis.

Purpose:

• To quantify plasma fibronectin levels throughout normal pregnancy, postpartum, in cord blood, and in cases of EPH gestosis.
• To compare these levels with those found in non-pregnant women.
• To assess the potential of fibronectin as a marker for EPH gestosis.

Summary:

• Plasma fibronectin concentrations were measured in non-pregnant women, during pregnancy (after 15 weeks), postpartum, in cord blood, and in EPH gestosis.
• Fibronectin levels at late gestation were similar to early second trimester and non-pregnant levels, remaining stable postpartum.
• Cord blood showed approximately half the fibronectin concentration of adult plasma, while EPH gestosis cases exhibited significantly elevated levels.

Impact:

• Provides normative data for plasma fibronectin during pregnancy and postpartum.
• Highlights significantly elevated fibronectin in EPH gestosis, suggesting its potential as a diagnostic or prognostic marker.
• Contributes to understanding the role of fibronectin in pregnancy complications.
