[Liver transplantation after exertion-induced heat stroke associated with fulminant liver failure].
OBJECTIVE
Describe the course of fulminant liver failure after exertional heat stroke.


METHODS
A 30-year-old man acclimated to the tropical climate, collapsed and became comatose with hyperthermia during a commando march in Gabon. Thirty-six hours later, the biological examination revealed moderate rhabdomyolysis and fulminant liver failure. An orthotoptic liver transplantation was performed at the 48th hour. Acute renal failure with severe rhabdomyolysis developed on the 4th day post-surgery while the patient was perfectly alert. His condition thereafter deteriorated and he died of chronic rejection 11 months after liver transplantation.


CONCLUSIONS
In its most serious forms exertional heat stroke is a multiple organ dysfunction syndrome of poorly understood pathogenesis. The reported case suggests that exertional heat stroke can cause fulminant liver failure, resulting either from the direct effect of heat on the hepatic parenchyma, or from acute hepatic ischemia due to blood redistribution made worse by the hypersecretion of antidiuretic hormone, a potent portal vasoconstrictor, which occurs in the heat acclimated subject.
