Journal Article
Association between sympathoadrenal activation, fibrinolysis, and endothelial damage in septic patients: A prospective study
2014
Overview
The purpose of this study is to investigate potential associations between sympathoadrenal activation and/or vasopressor/inotropic therapy and endothelial activation, damage, and coagulopathy in septic patients.
Septic patients included in the Scandinavian Starch for Severe Sepsis/Septic Shock trial who were expected not to receive catecholamines at screening preintervention (baseline) and had baseline blood sampled. Clinical, outcome data, and measurements of plasma concentration (p-) biomarkers reflecting sympathoadrenal activation, endothelial activation and damage, natural anticoagulation, fibrinolysis, cell damage, and platelet activation.
Sixty-seven patients were included, of whom 14 turned out to receive noradrenaline infusion at blood sampling. These 14 patients had p-noradrenaline 5-fold higher than patients not receiving catecholamines (n = 53), whereas no other baseline preintervention biomarkers differed. In the 53 patients not receiving catecholamines at blood sampling, endogenous p-noradrenaline correlated positively with adrenaline, syndecan 1, soluble vascular endothelial growth factor receptor 1, soluble CD40 ligand, tissue-type plasminogen activator, and plasminogen activator inhibitor 1 (PAI-1) and negatively with PAI-1/tissue-type plasminogen activator ratio (all P <.05) and was independently associated with syndecan 1, soluble vascular endothelial growth factor receptor 1, and PAI-1 (all P <.05), and 28- and 90-day mortality (P <.05).
In septic patients, endogenous noradrenaline was independently associated with biomarkers of endothelial activation, damage, fibrinolysis and mortality, comparable with findings in trauma and myocardial infarction patients. The catecholamine surge in critical illness may contribute to balance endothelial damage and procoagulation with hypocoagulability and hyperfibrinolysis in the circulating blood.
