Aim. To identify additional criteria for the diagnosis of severe preeclampsia (PE) in pregnant women based on an investigation of the expression of the early adhesion molecules, chemokine receptors, and markers of endothelial dysfunction in venous blood neutrophils and monocytes. Material and methods. One hundred and fifty patients with PE (74 with moderate PE, 76 with severe PE) and 70 women with a physiological course of pregnancy were tested for venous blood neutrophils and monocytes expressing adhesion molecules CD62L, CD11b, chemokine receptors CCR2 and CX3CR1, and the number of circulating endothelial cells (CECs). Results. When compared with women having uneventful pregnancy and patients with moderate PE, patients with severe PE had significantly lower levels of CD62L+neutrophils, but higher levels of CX3CR1+monocytes and neutrophils, and a greater number of CECs. The diagnostic thresholds for these parameters are informative in the diagnosis of PE severity. Conclusion. Measuring the relative levels of CD62L+, CX3CR1+ neutrophils and the number of CECs in the blood can be used for stratifying severity of PE with greater accuracy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
