Key result
Early-onset pre-eclampsia exhibited impaired trophoblast invasion and spiral artery remodeling, while late-onset pre-eclampsia showed compensation of chronic tissue hypoxia.
Why the study?
What are the morphological and immunohistochemical differences in the placental bed between early- and late-onset pre-eclampsia?
Population
150 pregnant women aged 18-43 years old delivered by cesarean section due to severe pre-eclampsia
Design
Cross-sectional

May refine pre-eclampsia subtyping; leaves open whether findings guide targeted therapies without prospective validation.

What are the morphological and immunohistochemical differences in the placental bed between early- and late-onset pre-eclampsia?
Early- and late-onset pre-eclampsia exhibit distinct pathogenetic mechanisms in the placental bed, supporting their clinical separation.
Ходжаева et al. (2015) conducted an observational in Severe pre-eclampsia (n=150). Early-onset pre-eclampsia vs. Late-onset pre-eclampsia was evaluated on Morphological and immunohistochemical characteristics of the placental bed. Early-onset pre-eclampsia exhibited impaired trophoblast invasion and spiral artery remodeling, while late-onset pre-eclampsia showed compensation of chronic tissue hypoxia.
