    Background: Endothelial activation is a key driver of multiple organ dysfunction syndrome (MODS). Soluble endoglin (sENG) is expressed by mature and progenitor endothelial cells and thought to have angiogenic properties. We sought to determine the association between sENG and pediatric sepsis associated MODS. Methods: Prospective observational study of pediatric septic shock. Primary outcome of interest was complicated course -a composite of death by (or) MODS on day 7 of illness. Secondary outcomes included individual organ dysfunctions. Endothelial biomarkers including sENG were measured using multiplex Luminex assays among patients with existing data on pediatric sepsis biomarker risk model data (PERSEVERE-II). Multivariable regression was used to test the independent association between sENG and clinical outcomes. Serum sENG concentrations across PERSEVERE-II mortality risk strata and correlations with established markers of endothelial dysfunction. Results: 306 critically ill children with septic shock were included. Serum sENG concentrations were higher among those with primary and secondary outcomes of interest, with the exception of acute neurological dysfunction. sENG was independently associated with increased odds of complicated course [adj OR 1.53 (95% CI: 1.02–2.27), p=0.038] and acute renal dysfunction [adj OR 1.84 (95%CI: 1.18–2.876), p=0.006]. sENG demonstrated graded responses across PERSEVERE-II risk strata and was positively correlated with endothelial biomarkers, except Angiopoietin-1. Conclusions: Serum soluble endoglin is independently associated with complicated course and acute renal dysfunction in pediatric septic shock. Future studies are required to validate our observational data and mechanistic studies are necessary to elucidate whether endoglin plays a organ-specific role in development or resolution of acute renal dysfunction in sepsis.
