The Effect of Maternal Blood Glucose on Umbilical Cord Blood Fibrinogen in Women With Gestational Diabetes.

BACKGROUND AND AIMS: Gestational diabetes mellitus (GDM) is delineated by the presence of glucose intolerance at any level that manifests or is initially identified during pregnancy. Factor I fibrinogen is among the most essential blood coagulation proteins. The concentration of fibrinogen influences platelet aggregation and blood viscosity. This study aimed to determine the correlation between fetal cord blood fibrinogen and plasma fibrinogen in pregnant women with GDM and between fetal cord blood fibrinogen and maternal blood sugar.

METHODS

A cross-sectional study was executed at Al-Elwiya Maternity Teaching Hospital in the obstetrics and gynecology department. The sample included 90 term pregnant women: 45 were confirmed to have GDM, and 45 healthy pregnant women served as control. Estimation of prelabor maternal fasting and random plasma glucose and plasma fibrinogen was performed. During delivery, blood was drawn from the umbilical cord to estimate neonatal plasma glucose and fibrinogen levels.

RESULTS

The mean maternal plasma fibrinogen level exhibited a notable increase in women with GDM compared to the control (330.11 ± 56.92 mg/dl versus 254.89 ± 41.01 mg/dl). The infants of diabetic mothers had significantly lower mean cord plasma glucose levels (65.71 ± 14.63 mg/dl versus 77.80 ± 7.81 mg/dl) and higher mean cord plasma fibrinogen levels (269.42 ± 25.91 mg/dl versus 229.69 ± 21.29 mg/dl). Umbilical cord plasma fibrinogen was correlated positively with maternal plasma sugar and fibrinogen.

CONCLUSION

A positive correlation between maternal and fetal cord fibrinogen levels was determined in women with GDM. Monitoring plasma fibrinogen levels in neonates of mothers with GDM could be facilitated by longitudinal, large-scale validation studies enabled by artificial intelligence as a new, evolving technique that contributes to more valuable outcomes. This would shed additional light on the course and function of plasma fibrinogen for a more comprehensive analysis of the fetal clotting system.
