Hemoperfusion and liver disease.

After first adventurous attempts to apply perfusion techniques to the treatment of liver diseases, more extensive experiences have been acquired in the last twenty years, not only in acute hepatic failure but also in some chronic liver diseases (mainly in CAH:chronic active hepatitis, and in primary biliary cirrhosis) and in a severe complication of them, that is cryoglobulinemia. Some experiences on this field that are found in literature, using both plasma exchange and hemoperfusion, are reviewed and some personal data are reported: 15 patients with acute viral liver failure (survival rate: 33%) and 5 patients with a CAH-linked (3 viral and 2 autoimmune) cryoglobulinemia, in whom a good control of the disease parameters was obtained.
