Decorin levels in early- and late-onset preeclampsia
Abstract
Objectives: Preeclampsia (PE) is a pregnancy complication caused by typically limited proliferation, apoptosis, migration,
and invasion of extra-trophoblast cells. Decorin (DCN) is a decidua-derived transforming growth factor (TGF)-binding
proteoglycan which exerts multiple physiological functions such as collagen fibrillogenesis, myogenesis, angiostasis, and
restraining placental invasiveness by adversely regulate proliferation, migration, and invasiveness of human extravillous
trophoblast cells. Preeclampsia is mainly classified as early- and late-onset PE according to the timing of the disease onset.
In the present study, we aimed to investigate the DCN levels in early-onset PE (EOPE, < 34 weeks) and late-onset severe PE
(LOPE, ≥ 34 weeks) and uncomplicated pregnancies.
Material and methods: In this case-control study, serum samples were obtained from 21 pregnant women with EOPE
and 29 pregnant women with LOPE, as well as from 38 healthy controls (n = 12 early-onset controls and n = 26 late-onset
controls) with uncomplicated pregnancies.
Results: The mean DCN level was statistically significantly higher in the early-onset PE controls than late-onset PE controls
(p = 0.040). Although the mean DCN level was higher in the early-onset PE controls than EOPE and LOPE groups, it did not
reach statistical significance (p = 0.119 and p = 0.117, respectively).
Conclusions: Although DCN has been thought to play a role in the pathophysiology of PE, our study results show that DCN
is not a useful predictive marker of EOPE and LOPE. Further large-scale studies are needed to draw a definitive conclusion.
