ABSTRACT
OBJECTIVE: We report fatal cases of multifocal ischemic injuries occurring in patients awaiting liver transplantation after severe concomitant paracetamol and cyclooygenase inhibitors self-poisoning. DESIGN AND SETTING: Case report in an intensive care unit. PATIENTS: In addition to signs of acute liver failure with a systemic inflammatory response syndrome, these three previously healthy young women demonstrated cutaneous vasoconstriction. One patient displayed a sudden ST-segment elevation with ventricular fibrillation. INTERVENTIONS: Angiography, plasma endothelin concentrations measurements, and autopsy. RESULTS: Radiography showed diffuse vasospasm on mesenteric and renal arteries, transiently reversed by vasodilators. We measured tenfold higher plasma endothelin concentrations than in healthy controls. Autopsy revealed no atherosis (including coronary arteries); organs showed multifocal ischemic injuries without thrombosis. CONCLUSIONS: Such injuries subsequent to dramatic vasoconstriction suggest that cyclooygenase inhibition has specific deleterious vascular side effects once systemic inflammatory response syndrome is in progress during paracetamol poisoning.
