Fibrin generation during the diabetic pregnancy

Area of Science:

• Obstetrics and Gynecology
• Endocrinology
• Hematology

Background:

• Pregnancy in insulin-dependent diabetic women carries risks like hypertension and fetal loss, often linked to clotting abnormalities.
• Fibrin catabolism plays a crucial role in hemostasis and its dysregulation may contribute to pregnancy complications.

Purpose of the Study:

• To investigate fibrin catabolism in pregnant women with insulin-dependent diabetes mellitus.
• To assess Fibrinopeptide A (FPA) levels as a marker of fibrin catabolism during diabetic pregnancy.

Main Methods:

• Longitudinal and cross-sectional study of 20 pregnant diabetic women (26-38 weeks gestation).
• Measurement of Fibrinopeptide A (FPA) by radioimmunoassay.
• Determination of Antithrombin III activity.

Main Results:

• Mean FPA levels were elevated in diabetic women compared to controls across gestational periods.
• Significant differences in FPA were observed in four of seven intervals.
• Elevated FPA persisted even in patients with good glycemic control (HbA1: 7.1% ± 1.2%).

Conclusions:

• Increased fibrin catabolism occurs in well-controlled diabetic pregnancies.
• Factors other than glucose regulation appear to influence fibrin catabolism and potentially pregnancy outcomes in diabetic mothers.
• Further prospective studies are needed, considering diabetes classification and glucose control levels.
