Association of plasma Decorin levels and markers of glycocalyx disruption with adverse events in women with severe preeclampsia. Pregnancy Hypertens 2023; 34:56-59.

Abstract
Identifying preeclamptic women with an increased risk of severe maternal complications can aid in timely interventions to optimize pregnancy outcomes. Newer biomarkers such as Decorin and markers of endo glycocalyx disruption were assessed in earlier studies for its role in predicting preeclampsia, but their role in identifying those with adverse maternal outcomes is limited. This study aimed to evaluate the association of these biomarkers with adverse maternal outcomes in women with severe pre-eclampsia. Markers of glycocalyx disruption may be further explored for their role along with clinical features and other biomarkers in identifying women at higher risk of maternal complications.

Roles of Two Small Leucine-Rich Proteoglycans Decorin and Biglycan in Pregnancy and Pregnancy-Associated Diseases. Int J Mol Sci 2021; 22:ijms221910584. [PMID: 34638928 PMCID: PMC8509074 DOI: 10.3390/ijms221910584] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2021] [Revised: 09/21/2021] [Accepted: 09/22/2021] [Indexed: 11/18/2022] Open
Abstract
Two small leucine-rich proteoglycans (SLRP), decorin and biglycan, play important roles in structural–functional integrity of the placenta and fetal membranes, and their alterations can result in several pregnancy-associated diseases. In this review, we briefly discuss normal placental structure and functions, define and classify SLRPs, and then focus on two SLRPs, decorin (DCN) and biglycan (BGN). We discuss the consequences of deletions/mutations of DCN and BGN. We then summarize DCN and BGN expression in the pregnant uterus, myometrium, decidua, placenta, and fetal membranes. Actions of these SLRPs as ligands are then discussed in the context of multiple binding partners in the extracellular matrix and cell surface (receptors), as well as their alterations in pathological pregnancies, such as preeclampsia, fetal growth restriction, and preterm premature rupture of membranes. Lastly, we raise some unanswered questions as food for thought.

Abstract
Preterm birth is a leading cause of neonatal mortality in the US and globally, with preterm premature rupture of fetal membranes (PPROM) accounting for one third of preterm births. Currently no predictive diagnostics are available to precisely assess risk and potentially reduce the incidence of PPROM. Bigycan and decorin, the main proteoglycans present in human fetal membranes, are involved in the physiological maturation of fetal membranes as well as in the pathophysiology of preterm birth. The serum protein sex hormone-binding globulin (SHBG) has recently been identified as a predictor of spontaneous preterm birth. We hypothesize that the balance between serum decorin and biglycan on one hand and SHBG on the other hand may provide insight into the status of the fetal membranes in early pregnancy, thereby predicting PPROM prior to symptoms. Using chart review, 18 patients with confirmed cases of PPROM were identified from 2013-2016. Second trimester residual serum was retreived from freezer storage for these cases along with 5 matched controls for each case. The biomarkers biglycan, decorin and SHBG were analyzed first separately, then in combination to determine their ability to predict PPROM. The predictive score for the combined model displays an AUC = 0.774. The ROC curve of the predicted score has an optimal threshold of 0.238 and a sensitivity and specificity of 0.72 and 0.84 respectively. This prenatal serum panel is a promising serum screening-based biochemical model to predict PPROM in asymptomatic women.

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 14 weeks, 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 ± 6.88 ng/mL for the PE group while 9.75 ± 9.82 ng/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.

Abstract
The origin and regulation of stem cells sustaining trophoblast renewal in the human placenta remain unclear. Decorin, a leucine-rich proteoglycan restrains trophoblast proliferation, migration/invasiveness and endovascular differentiation, and local decorin overproduction is associated with preeclampsia (PE). Here, we tested the role of decorin in human trophoblast stem cell self-renewal and differentiation, using two models: an immortalized first trimester trophoblast cell line HTR-8/SVneo (HTR) and freshly isolated primary trophoblast (p-trophoblast) from early first trimester (6-9 weeks) placentas. Self-renewal capacity was measured by spheroid forming ability of single cells on ultra-low attachment plates for multiple generations. Markers of embryonic stem (ES) cells, trophoblast stem (TS) cells and trophoblast were used to identify stem cell hierarchy. Differentiation markers for syncytial and extravillous (EVT) pathways were employed to identify differentiated cells. Bewo cells were additionally used to explore DCN effects on syncytialization. Results reveal that the incidence of spheroid forming stem-like cells was 13-15% in HTR and 0.1-0.4%, in early first trimester p-trophoblast, including a stem cell hierarchy of two populations of ES and TS-like cells. DCN restrained ES cell self-renewal, promoted ES to TS transition and maintenance of TS cell stem-ness, but inhibited TS cell differentiation into both syncytial and EVT pathways.

Abstract
OBJECTIVE Preeclampsia (PE), can be classified according to the timing of disease onset: early-onset PE occurs before the 34th gestational week and late-onset PE occurs in the 34th gestational week or later. The aim of this study was to determine whether total antioxidant status (TAS), and total oxidant status (TOS), ADAMTS-12 and decorin levels differ among early-onset severe PE (EOS-PE), late-onset severe PE (LOS-PE) and uncomplicated pregnancies. METHODS In this case-control study, placental samples obtained from 25 pregnant patients with EOS-PE, 26 pregnant patients with LOS-PE and 28 healthy patients with uncomplicated pregnancies (control group). RESULTS Placenta levels of decorin and TOS were significantly higher and TAS was significantly lower in the EOS-PE and LOS-PE groups than in the control group. These alterations were more prominent in patients with EOS-PE than in patients with LOS-PE. There were no significant differences in the ADAMTS-12 levels of the groups. CONCLUSION The distinctly higher rate of negative perinatal outcomes in both EOS-PE and LOS-PE patients is well evidenced. However, the main questions that need to be answered are whether the only difference between these two diseases is the time of their onset and whether the only difference between them with respect to fetal morbidity and mortality is prematurity.
