Endothelin production in sepsis and the adult respiratory distress syndrome

Abstract
Septic shock is characterised by a decrease in systemic vascular resistance. Nevertheless, regional increases in vascular resistance can occur which may predispose to organ dysfunction, including the adult respiratory distress syndrome (ARDS). Because endothelial damage is a major feature of acute lung injury, we examined whether the potent endothelial vasoconstrictor peptide endothelin-1 plays a pathophysiological role in sepsis of ARDS.
