Histopathological changes in the liver following a paracetamol overdose: correlation with clinical and biochemical parameters.
The histological appearances of the liver damage occurring after a paracetamol overdose are described in liver biopsies from 104 patients, of whom 38 developed fulminant hepatic failure. Confluent centrilobular necrosis of varying extent was followed by rapid disappearance of necrotic cells, leaving areas of reticulin collapse and a usually mild inflammatory reaction. ⋯ An HVF value (normal 85 +/- 5 per cent.) of less than 40 per cent. in a biopsy taken within 10 days of the overdose was found only in patients who died. However, HVF measurements on biopsies from three survivors taken later than 10 days after the overdose shows that survival is possible below this critical level.
