  • Title: Maternal serum soluble adhesion molecule levels at 11+0-13+6 weeks and subsequent development of pre-eclampsia.
    Author: Parra-Cordero M, Turan OM, Kaur A, Pearson JD, Nicolaides KH.
    Journal: J Matern Fetal Neonatal Med; 2007 Nov; 20(11):793-6. PubMed ID: 17943642.
    Abstract:
    OBJECTIVES: We sought to examine whether the maternal serum concentration of soluble vascular cell adhesion molecule 1 (sVCAM-1) and intercellular adhesion molecule 1 (sICAM-1) at 11+0-13+6 weeks of gestation could improve the prediction for subsequent development of pre-eclampsia. METHODS: A nested case-control prospective study of pregnancies having uterine artery Doppler routinely at 11+0-13+6 weeks of gestation was conducted to determine the maternal serum concentration of sICAM-1 and sVCAM-1 in peripheral blood samples obtained from 18 women who later developed pre-eclampsia and 60 unaffected women. RESULTS: The mean uterine artery pulsatility index was higher (2.2 +/- 0.6 vs. 1.8 +/- 0.5, p < 0.05) in the pre-eclampsia compared with the unaffected pregnancies. There were no significant differences between the groups in the mean serum concentration of either adhesion molecule. CONCLUSIONS: These results suggest that there is no endothelial activation before the appearance of clinical signs of pre-eclampsia. Therefore, these biochemical markers are unlikely to become early predictors of this condition.
