The first-trimester serum decorin levels as a potential predictor of preeclampsia.

Abstract

Background Preeclampsia (PE) is a multisystem disease and is still among the leading causes of maternal and neonatal morbidity and mortality. Inadequate trophoblast invasion plays a key role in the PE pathogenesis. The proliferation, migration, and invasion of extravillous trophoblasts (EVTs) is primarily controlled by the decidua-derived transforming growth factor beta (TGF-β) and decorin. In this study, we aimed to investigate the clinical utility of serum decorin levels measured in the 11th to 14th gestational weeks to predict preeclampsia during the following weeks of gestation. Materials and Methods A total of 600 pregnant women, whose age and gestational age ranged from 18 to 40 years and 11 to 14weeks, were included. Venous blood samples were obtained and stored at-80°C. Subsequently, the patients who developed preeclampsia and healthy controls with a similar body mass index were identified and their first-trimester blood samples were analyzed for serum decorin levels. Results The mean serum decorin level was 8.76±6.88ng/mL for the PE group while 9.75±9.82ng/mL for the control group. No statistically significant difference was found between the two groups (p=0.838). Conclusion We observed that the serum decorin levels during the 11th to 14th weeks of gestation showed no predictive value for preeclampsia in pregnant women. However, more accurate conclusions about the clinical utility of decorin as a biomarker of preeclampsia would require further studies with larger samples including more patients with EOS-PE.
