Abstract
OBJECTIVE
TO determine whether changes in plasma levels of thrombomodulin from antepartum to postpartum reflect the postpartum regression of preeclampsia.
METHODS
Twenty-four preeclamptic women and 34 healthy, normotensive women with singleton pregnancies were studied in the third trimester. Plasma levels of thrombomodulin in the antepartum and postpartum periods were measured by a two-site immunoenzymatic assay. Two-tailed Student t test and paired-comparison t test were used for statistical analyses. The results were expressed as mean ± standard error.
RESULTS
Antepartum plasma thrombomodulin levels in preeclampsia were significantly higher than postpartum levels (71.3 ± 8.5 versus 55.5 ±5.4 ng/mL; P =.006), which was not seen in the normotensive controls (49.9 ±3.1 versus 44.2 ±3.8 ng/mL; P >.05). Antepartum plasma levels of thrombomodulin in preeclamptic women were signiftcantly higher than those in the normotensive controls (P =.01). However, postpartum plasma levels of thrombomodulin in preeclamptic women were not significantly higher than those in the normotensive controls (P >.05).
CONCLUSION
Significantly decreased postpartum plasma thrombomodulin levels in preeclamptic pregnancies strongly correspond to clinical postpartum regression of preeclampsia. (J Soc Gynecol Invest 1997; 4:135-137) Copyright © 1997 by the Society for Gynecologic Investigation.
