Maternal serum soluble adhesion molecule levels at 11+0-13+6 weeks and subsequent development of pre-eclampsia.

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.
