      Degradation of the endothelial glycocalyx is recognized as a major part of the pathophysiology of sepsis. Previous clinical studies, mostly conducted in intensive care settings, showed associations between glycocalyx shedding and clinical outcomes. We aimed to explore the association of plasma syndecan-1, a marker of glycocalyx degradation, with the subsequent fluid requirements and clinical outcomes of emergency department patients with sepsis.


      This was a post hoc analysis of a randomized trial of fluid resuscitation in the emergency department. The study was conducted in the emergency department of an urban 1500-bed tertiary care center. The data of 95 adults who were diagnosed with sepsis-induced hypoperfusion and had undergone baseline syndecan-1 measurement were included. The syndecan-1 levels at baseline (T0) and hour 6 (T6) were studied to characterize their association with clinical outcomes, including subsequent fluid administration, organ failure outcomes and mortality.


      The median syndecan-1 levels at T0 and T6 were 207 (IQR 135–438) and 207 (IQR 128–490) ng/ml, respectively. Syndecan-1 levels at T0 were correlated with baseline sequential organ failure assessment (SOFA) score (ρ = 0.35, p < 0.001). Syndecan-1 levels at both T0 and T6 were correlated with subsequent fluid administration over 24 and 72 h and associated with the diagnosis of septic shock, the maximum dose of vasopressors and the need for renal replacement therapy (p < 0.05). Higher syndecan-1 levels at T6 were associated with higher 90-day mortality (p = 0.03).


      In the emergency department, syndecan-1 levels were associated with fluid requirements, sepsis severity, organ dysfunction, and mortality.
