Effects of anticopper therapy on hepatocellular mitochondria in patients with Wilson's disease: an ultrastructural and stereological study.


Liver biopsy specimens from 7 patients with Wilson's disease (hepatolenticular degeneration), obtained before and after 3 to 5 years of D-penicillamine therapy, were studied by electron microscopy and stereology. The characteristic mitochondrial abnormalities encountered in the hepatocytes of untreated patients were less pronounced or disappeared after treatment in 5 of the 7 patients. Simultaneously, relative mitochondrial volume, surface density of the external mitochondrial membranes, and the number of these profiles per unit area increased, whereas abnormal elevations SGOT and SGPT returned to normal levels.
