Purpose: The aim of the current study is to determine, correlate and compare the plasma lipoprotein-associated phospholipase A2 (Lp-PLA2), vitronectin (Vn), Plasminogen activator inhibitor-1 (PAI-1) activity and tissue plasminogen activator (t-PA) levels in early-onset preeclampsia, late-onset preeclampsia and in control pregnant women. Methods: A total of 79 individuals, 30 early-onsets, and 22 late-onset preeclamptic and 27 control pregnant women were included into the scope of this study. Enzyme-linked immunosorbent assay procedure was used to determine the serum Lp-PLA2 and plasma Vn, t-PA antigen and PAI-1 activity levels. Serum C-reactive protein (CRP) levels were measured immunoturbidimetrically in routine clinical chemistry analyser. Results: In patients with preeclampsia, Lp-PLA2, PAI-1, t-PA, CRP and blood pressures levels were increased (p = 0.000) and correlated with each other. Vn levels were decreased (p = 0.016) but not correlated with other parameters in preeclamptic patients. Conclusion: We are of the opinion that increased Lp-PLA2 levels may partially contribute to endothelial dysfunction by the progression of inflammation. In addition, increased complex formation with Vn is likely to bring about the increase of PAI-1 activity in patients with preeclampsia. Moreover, increased t-PA and decreased Vn levels may also be the consequences of compensatory mechanisms against disease progression.
