Sepsis Diagnosis and Treatment

Heart failure (HF) is a leading cause of hospitalization throughout the world, and the mortality rate remains elevated. HF is frequently complicated by acute kidney injury (AKI), worsening the patient's prognosis. There have been no studies evaluating the role that endothelial glycocalyx damage plays in HF patients and its association with AKI and mortality.We measured several endothelial biomarkers in 201 consecutive patients with acute decompensated HF (ADHF) during emergency department (ED) admission. In-hospital mortality, AKI development and 6-month mortality rates were assessed. ADHF patients with worsening renal function had higher levels of syndecan-1 but not those patients with stable chronic kidney disease. Syndecan-1 levels during ED admission were predictive for AKI during the hospital stay (AUC 0.741, P<0.001) and had an even better discriminatory capacity in more severe AKI (AUC 0.812, P<0.001). Additionally, after adjusting for several confounding factors, including biomarkers of endothelial function and endothelial cell activation, syndecan-1 remained associated with in-hospital mortality rates. On a Cox multivariate analysis regression, syndecan-1 was associated with 6-month mortality rates.The concentration of syndecan-1, a marker of glycocalyx damage measured during ED admission, is valuable in assessing the risk of developing AKI and in-hospital mortality. Its association with mortality is strong after 6-month follow-up.
