Variation and clinical value of endothelial glycocalyx in the patients with septic shock

2016 
Abstract To explore the variation and clinical value of the degradation of endothelial glycocalyx in the patients with septic shock. A prospective case control study was conducted. Patients of 18 years or older diagnosed with septic shock and admitted to Department of Critical Care Medicine of Affiliated Hospital of Binzhou Medical University from June 2014 to May 2015 were enrolled. The levels of degradation products, including hyaluronic acid (HA) and heparin sulfate (HS), at 0, 6, 12, 24, 48 hours were determined, while 20 healthy people were enrolled and served as controls. The changes of HA and HS were analyzed in the patients with septic shock. The differences of HA and HS between survival group and death group after 28 days were also analyzed. The relationships between HA, HS and tumor necrosis factor-α (TNF-α), sequential organ failure assessment (SOFA) score, arterial blood lactate (Lac), platelet, albumin were analyzed by Pearson correlation analysis. The receiver-operating characteristic (ROC) curve was plotted to assess the prognostic value of HA and HS for patients with septic shock. Thirty-one patients diagnosed as septic shock were enrolled, among whom 17 patients died after 28 days, with a mortality of 54.8%. The levels of HA and HS in patients with septic shock were increased significantly as compared with those of health control group, peaked at 48 hours, and the levels of HA and HS at 48 hours were significantly higher than those at 0 hour [HA (μg/L): 119.47±32.44 vs. 94.84±23.63, HS (μg/L): 72.83±19.03 vs. 58.83±16.63, both P
