Alkaline phosphatase isoenzymes in liver cirrhosis.

The study of a group of 114 hepatic patients allowed us to demonstrate the presence of an isophosphatase band, called ALP4, which can be of value as an index of evolutive cirrhosis. A certain correlation between the presence of this alkaline phosphatase isoenzyme in serum and histological evidence of moderate or extreme inflammatory response in liver biopsies was shown.
