BackgroundThe hypercoagulability of pregnancy is exaggerated in pre-eclamptic state because of endothelial activation with resultant production of some endothelial derived proteins that are said to be inhibitors of fibrinolysis. This study compares these proteins like tPA, PAI-1 and D-dimers in normal pregnant women and the pre-eclamptic women.MethodologyThis was a comparative cross-sectional study. Eighty-five pre-eclamptic women were recruited as subjects and eighty five age, trimester and parity matched normotensive pregnant women as controls. Levels of PT, aPTT, tPA, PAI-1, D-dimer protein were determined in blood samples of subjects and controls. Urinalysis was performed with dipstick method on their urine samples. Data generated was analysed using the IBM®SPSS 20.0 (2011) soft ware packages and the level of significance was a p-value <0.05.ResultsThe mean age of the respondents was 29.9±5.2 years. The median(25th–75th percentile) values of D-dimer, tPA, and PAI-1 of subjects were 730 (305.000–1560.000ng/ml), 0.11 (0.065–0,300ng/ml) and 3.65 (2.970–4,400ng/ml) respectively which were significantly higher than the corresponding values in the controls of 520 (24.000–1030.000ng/ml), 0.05 (0.040–0.090ng/ml and 2.650 (2.125–3.400ng/ml) respectively, p<0.05 each.ConclusionThe abnormal levels of PAI-1, D-dimer and tPA imply that they contribute to the exaggerated hypercoagulabilty state in pre-eclampsia thus, measuring their levels can help in the management of the condition.
