title: [Acute hepatic failure and renal damage. Experimental and clinical studies].
abstract: Renal damage in acute hepatic failure induced in the pig by means of an hepatic state, temporary or permanent devascularisation Amanita phalloides poisoning or orthotopic liver transplant proved of slight degree, particularly in animals treated with replacement therapy. In the cases of animals that died in acute hepatic coma, on the other hand, renal cortex ischaemia and marked medullary congestion were constant. Histologically, the damage consisted of slight tubular nephrosis; this was more apparent in the proximal tubules. Evaluation of renal damage in 38 patients with acute hepatic failure was more complicated owing to the variety of clinical conditions (level of coma, hypovolaemia, intensive care and hepatic assistance). Nevertheless, a clear relation was established between the degree of liver damage and blood creatinine and creatinine clearance values. All patients who died presented liver cell necrosis of over 75%, blood creatinine values of more than 2 mg/100 ml, and less than 50 ml/min clearance. Tubular nephrosis was the predominant lesion. It appeared that renal damage was primarily pre-renal. No signs of a true hepatorenal syndrome could be made out.
