Abstract
Objectives
Preeclampsia (PE) is a serious complication of pregnancy. The fibrinolytic
system play crucial roles regarding placentation and evolution of PE.
Aim
To study comprehensively components of the fibrinolytic system and fibrin
lysability in women with PE.
Design and Methods
117 women with PE and matched controls were included. Tissue type plasminogen
activator (t-PA), plasminogen, PAI-1, plasmin inhibitor (PI), D-dimer, the
fibrinolytic potential of dextran sulphate euglobulin fraction (DEF), PAI-2,
polymere PAI-2, fibrin clot lysability, thrombin activatable fibrinolysis
inhibitor (TAFI) and fibrinogen were assessed.
Results
Women with PE had significantly increased concentrations of t-PA and PAI-1,
whereas the plasma concentration of PAI-2 was significantly lower compared
to controls, p < 0.0001. Polymere PAI-2 was detected in both groups. DEF,
TAFI and fibrinogen were not different between the groups. D-dimer was
significantly increased and plasminogen/PI together with fibrin clot
lysability time decreased in the PE-group, p = 0.0004 p = 0.04,
p = 0.03, p < 0.0001 respectively.
Conclusion
This study demonstrates that PE is associated with an affected t-PA/PAI-1
system, decreased PAI-2 and increased fibrin lysability. Furthermore, PAI-2
has the potential to polymerize during pregnancy.
