Plasma Endothelial Glycocalyx Components as a Potential Biomarker for Predicting the Development of Disseminated Intravascular Coagulation in Patients With Sepsis.

BACKGROUND: Sepsis coagulopathy or disseminated intravascular coagulation (DIC) mainly due to progressive endothelial disruption and damage. The glycocalyx is expressed on the endothelial cell surface and contributes to anti-thrombogenicity, anti-inflammatory, and regulates vascular permeability. We aimed to evaluate the clinical utility of plasma glycocalyx components as biomarkers in predicting the onset of DIC in sepsis. MATERIALS AND METHODS: This was a prospective observational study of 45 patients with sepsis (June to December 2018). Demographic, clinical (Acute Physiology, Age, Chronic Health Evaluation II [APACHE II], Sequential Organ Failure Assessment [SOFA]), and laboratory data from medical records were analyzed. Endothelial glycocalyx components (syndecan-1, heparan sulfate, hyaluronan) were measured using an ELISA kit. RESULTS: Among the 45 patients (23, sepsis; 22, septic shock), plasma syndecan-1, heparan sulfate, and hyaluronan levels were higher in those with septic shock and were positively correlated with disease severity as determined by the APACHE II and SOFA scores and lactate levels. Receiver operating characteristic curve analysis revealed high sensitivity and specificity of syndecan-1 for predicting septic shock. Further, these levels were compared between patients with or without the development of DIC. Plasma syndecan-1 and hyaluronan levels were significantly elevated in patients with DIC compared to those in patients without DIC and were strongly associated with activated partial thromboplastin time, prothrombin time, and platelet counts. Area under the curve values for predicting DIC based on syndecan-1 and hyaluronan levels measurements were 0.774 and 0.740, respectively. CONCLUSIONS: Increased plasma syndecan-1 and hyaluronan levels may be indicators of disease severity and useful predictors for DIC development in sepsis.
