Summary

Plasminogen activator inhibitor-1 (PAI-1) is important for maintaining pregnancy. Aberrantly increased PAI-1 levels may contribute to thrombosis and inflammation, leading to pregnancy loss. This study investigated the association of PAI-1 polymorphisms (PAI-1 rs2227631 [-844G>A], rs1799889 [-675 4G/5G], rs6092 [43G>A], rs2227694 [9785G>A], and rs7242 [11053T>G]) with idiopathic recurrent pregnancy loss (RPL) in Korean women. We screened 308 RPL patients and 227 control participants for five PAI-1 polymorphisms. Genotyping of PAI-1 was performed by polymerase chain reaction-restriction fragment length polymorphism assay. PAI-1 4G4G and -844AA/ 4G4G/11053GG genotypes were associated with RPL. PAI-1 -844A/4G/43G/9785G/11053G haplotype was connected to hypofibrinolytic status (i.e. increased levels of plasma PAI-1, increased numbers of platelets, reduced prothrombin time, and reduced activated partial thromboplastin time). Moreover, PAI-1 11053TG+GG frequency was positively related to plasma homocysteine and urate levels, whereas -844AA frequency was associated with plasma folate concentrations according to ordinal logistic regression analysis. Based on these results, we propose that PAI-1 -844G>A, 4G/5G, and 11053T>G polymorphisms are markers of RPL.
