Circulating concentrations of soluble endoglin (CD105) in fetal and maternal serum and in amniotic fluid in preeclampsia - 22/08/11
Résumé |
Objective |
We explored whether concentrations of soluble endoglin in fetal serum and amniotic fluid and in maternal serum were elevated in preeclampsia.
Study Design |
Umbilical vein serum, amniotic fluid, and maternal serum from 42 preeclamptic and 43 uncomplicated pregnancies that were delivered by cesarean section were analyzed by enzyme-linked immunosorbent assay for soluble endoglin.
Results |
Median maternal serum and amniotic fluid soluble endoglin concentrations were elevated in preeclampsia, compared with control pregnancies (66.9 ng/mL vs 15.1 ng/mL; P < .001, and 1.9 ng/mL vs 0.6 ng/mL; P < .001). Low concentrations of soluble endoglin were found in fetal circulation, which did not differ between preeclampsia and control pregnancies (5.0 ng/mL vs 4.7 ng/mL; P = .2). Maternal serum soluble endoglin levels correlated with circulating soluble fms-like tyrosine kinase 1 concentrations.
Conclusion |
We confirmed elevated soluble endoglin in maternal circulation in preeclampsia, which correlated with soluble fms-like tyrosine kinase 1 concentrations and soluble fms-like tyrosine kinase 1/placental growth factor ratio. The fetus appears not to contribute to elevated circulating maternal soluble endoglin concentrations in preeclampsia.
