OBJECTIVE: To investigate the plasma and placental levels of interleukin-10 (IL-10), transforming growth factor-beta1 (TGF-beta1), and epithelial-cadherin (E-cadherin) in normotensive and preeclamptic pregnancies. METHODS: The study population consisted of 33 women with normotensive pregnancy and 35 women with preeclampsia. Peripheral venous blood samples were collected before labor (35.3 +/- 1.1 and 34.2 +/- 3.4 weeks' gestation for normotensive and preeclamptic pregnancies, respectively), and placental tissues were obtained after delivery. Maternal plasma and placental homogenate IL-10, TGF-beta1, and E-cadherin levels were determined by enzyme-linked immunosorbent assay. RESULTS: The mean plasma and placental levels of IL-10, TGF-beta1, and E-cadherin were significantly higher in preeclamptic than normotensive patients (P <.001). The plasma and placental levels of IL-10, TGF-beta1, and E-cadherin significantly increased with the increments in diastolic blood pressure (P <.001). CONCLUSION: IL-10, TGF-beta1, and E-cadherin may be involved in the pathologic process of preeclampsia. The pathophysiologic changes associated with preeclampsia may stem in part from the overproduction of these placental mediators.
