Abstract:
:Current concepts of the pathogenesis of preeclampsia involve the generalized dysfunction of maternal vascular endothelial cells. We measured the endothelial isoform of fibronectin as a marker of endothelial cell injury throughout pregnancy in a prospective, case-control study. Nineteen women met strict criteria for the diagnosis of preeclampsia. Nineteen normal pregnant women, and 19 women with gestational hypertension but without other stigmata of preeclampsia (transient hypertension) were selected from the same cohort and matched according to race, age, nulliparity, and gestational age at delivery. Plasma levels of cellular fibronectin were significantly elevated in women meeting strict clinical and biochemical criteria for preeclampsia but not in women with normal pregnancies or transient hypertension. Moderate but significant elevations in mean levels were found in the second trimester in women destined to have preeclampsia, as compared with matched normal and transient hypertension groups (p less than 0.05). The results indicate that elevated plasma levels of cellular fibronectin are not simply the result of increased blood pressure but reflect a maternal insult specific to the syndrome of preeclampsia. Elevation of the mean concentration during the midtrimester is consistent with the hypothesis that endothelial cell injury is a specific lesion that occurs early in the course of preeclampsia, before clinical signs and symptoms.
