Aggressive non-alcoholic steatohepatitis following rapid weight loss and/or malnutrition.

ABSTRACT: While non-alcoholic steatohepatitis is a slowly progressive disease, patients may rarely present in acute liver failure. We describe six patients who developed severe hepatic dysfunction following rapid weight loss or malnutrition.

Pathologic findings were characterized by advanced alcoholic steatohepatitis-like features, including extensive/circumferential centrizonal pericellular fibrosis, central scar with perivenular sclerosis/veno-occlusion with superimposed hepatocellular dropout, abundant/prominent hepatocellular balloons, and numerous Mallory-Denk bodies, b
