Soluble fibrinogen--fibrin complexes in intrauterine growth retardation
Insights
Pregnant women with intrauterine growth retardation showed higher soluble fibrinogen-fibrin complex levels. This may indicate increased placental coagulation, suggesting potential for antenatal diagnosis using coagulation tests.
Area of Science:
- Obstetrics and Gynecology
- Hematology
- Perinatology
Background:
- Intrauterine growth retardation (IUGR) is a significant complication of pregnancy.
- Placental insufficiency and altered coagulation are implicated in IUGR.
- Soluble fibrinogen-fibrin complexes (SFFC) are markers of coagulation activation.
Purpose of the Study:
- To investigate SFFC levels in pregnancies with IUGR.
- To explore the association between SFFC and placental coagulation in IUGR.
- To assess the potential diagnostic utility of coagulation markers for IUGR.
Main Methods:
- Plasma samples were collected from pregnant women with IUGR and normal pregnancies.
- Soluble fibrinogen-fibrin complex levels were measured.
- Histological examination of placental tissue was performed.
Main Results:
- Significantly higher SFFC levels were observed in women with IUGR compared to normal pregnancies.
- Findings suggest increased local intravascular coagulation within the placenta in IUGR pregnancies.
- Histological evidence supported increased placental coagulation in complicated pregnancies.
Conclusions:
- Elevated SFFC levels may serve as an indicator of placental coagulation activation in IUGR.
- Sensitive methods for coagulation, fibrinolysis, and platelet function could aid in antenatal IUGR diagnosis.
- Further research into coagulation markers for IUGR is warranted.
Abstract:
Soluble fibrinogen--fibrin complex levels were found to be significantly higher in plasma samples from pregnant women with babies suffering from intrauterine growth retardation, when compared with levels found in normal pregnancy. As soluble fibrinogen--fibrin complexes are formed following activation of the coagulation pathway in vitro and in vivo these findings may reflect the increased local intravascular coagulation within the placenta demonstrated histologically in pregnancies complicated by growth retardation. The use of more sensitive methods for detecting alterations in coagulation, fibrinolysis and platelet function may prove useful in the diagnosis of intrauterine growth retardation antenatally.
