Background: recurrent abortion is considered one of the most common complications that occur during pregnancy and counts for 15% of pregnancies that are recognized clinically. Many causes can be attributed to the recurrent pregnancy loss e.g. chromosomal anomalies, thrombophilic disorders, uterine anomalies, endocrine abnormalities and fetal anomalies. Thrombophilia can be either hereditary or acquired. Multiple genes had been implicated in the pathogenesis of the thrombophilia. Previous studies have indicated that genetic polymorphism of the plasminogen activator inhibitor-1 gene (PAI-1) may be associated with recurrent abortion.
Aim: The aim of the present study was to investigate whether plasminogen activator inhibitor-1 (-675 4G/5G) gene polymorphism is associated with the occurrence of recurrent pregnancy loss or not.
Methods: DNA samples were collected from sixty six female patients with recurrent abortion (33 primary abortion, 33 secondary abortion) and thirty four healthy controls with normal pregnancy for detection of plasminogen activator inhibitor-1 (-675 4G/5G) gene polymorphism by restriction fragment length polymorphism PCR.
Results: there was a significant association between PAI-1(-675 4G/5G) polymorphism and the occurrence of recurrent pregnancy loss.
Conclusion: Our results assumed that PAI-1 (-675 4G/5G) polymorphism is associated with recurrent pregnancy loss.
