title: [Increased plasma endothelin concentrations in patients after liver transplantation and in liver cirrhosis].
abstract: Endothelin, one of the most potent vasoconstrictors known today, is released by the vascular endothelium. Patients after liver transplantation and patients with liver cirrhosis show significantly higher plasma endothelin concentrations and significantly reduced results in the quantitative liver function tests (ICG-HL, GEC, Lidocaine-HL, MEGX) compared with healthy control persons. The plasma endothelin concentrations were better correlated with the more liver bloodflow dependent function tests (ICG-HL, Lidocaine-HL) than with the more metabolic-capacity dependent function tests (GEC, MEGX). As cyclosporine A in vitro can increase the liberation of endothelin, we conclude that in patients after liver transplantation an endothelin mediated cyclosporine induced hepatotoxicity might be the reason for the demonstrated association.
