OBJECTIVE: Endostatin, an important anti-angiogenic factor produced by endothelial cells, is elevated in established pre-eclampsia. We measured maternal serum endostatin concentrations in early pregnancy associated with later pre-eclampsia and intrauterine growth retardation (IUGR).
DESIGN: Retrospective case-control study.
SETTING: University Central Hospital.
SAMPLE: Serum samples were collected at 12-15 and 16-20 gestational weeks from a total of 124 pregnant women of whom 49 developed pre-eclampsia, 16 gave birth to infants with IUGR without pre-eclampsia, and 59 remained normotensive giving birth to healthy, normal-weight infants.
METHODS: Enzyme-linked immunosorbent assay.
MAIN OUTCOME MEASURES: Endostatin concentrations in serum.
RESULTS: At 12-15 gestational weeks, there was no difference in median endostatin concentrations between the groups. At 16-20 gestational weeks, the median endostatin concentration was higher in the women with subsequent pre-eclampsia (p=0.026), especially preceding a later severe form of the disease (p=0.041), than in the controls. The results were further confirmed by receiver operating characteristic (ROC) analysis showing an area under the curve (AUC) of 0.64 (95% confidence interval: 0.50-0.81) for endostatin to identify subsequent pre-eclampsia, and 0.71 (0.53-0.89) in cases of severe pre-eclampsia. Optimal cut-off values were determined and used for calculations of sensitivity and specificity, which were 80 and 52% (cut-off value = 58.0 microg/L) in pre-eclampsia, and 80 and 65% (cut-off value = 65.5 microg/L) in the severe form of the disease.
CONCLUSIONS: The concentrations of endostatin in maternal serum at 16-20 weeks' of gestation are associated with an increased risk of pre-eclampsia but not IUGR.
