In order to evaluate the behaviour of alpha-fetoprotein (AFP) and Tissue Polypeptide Antigen (TPA) in non neoplastic chronic hepatic diseases 60 patients suffering from chronic hepatitis have been studied, 28 of them with different ethiology cirrhosis, 4 with primary biliary cirrhosis (CBP), 18 with chronic active hepatitis (ECA), 5 with chronic persistent hepatitis (ECP), 3 suffering from alcoholic and 2 drug-induced hepatitis. In each case the diagnosis was biopsy-proved. We have found that TPA clearly shows an increase in about 90% of cirrhosis and in about 50% of ECA. Moreover, the group with non-A, non-B (NANB) cirrhosis and chronic hepatitis has shown a statistically significant correlation between TPA and alanine aminotransferase (ALT). On the other hand, AFP hants' shown statistically significant variations. The reasons of the TPA increase must probably be looked for in the marked sensitivity of this protein to non neoplastic tissues in rapid regeneration, in addition to the sensitivity to neoplastic tissues. Further studies will be carried out to evaluate the usefulness of TPA to tracing possible cytolitic relapses or any resumption of activity in hepatic cirrhosis.

Abstract
In order to evaluate the behaviour of alpha-fetoprotein (AFP) and Tissue Polypeptide Antigen (TPA) in non neoplastic chronic hepatic diseases 60 patients suffering from chronic hepatitis have been studied, 28 of them with different ethiology cirrhosis, 4 with primary biliary cirrhosis (CBP), 18 with chronic active hepatitis (ECA), 5 with chronic persistent hepatitis (ECP), 3 suffering from alcoholic and 2 drug-induced hepatitis. In each case the diagnosis was biopsy-proved. We have found that TPA clearly shows an increase in about 90% of cirrhosis and in about 50% of ECA. Moreover, the group with non-A, non-B (NANB) cirrhosis and chronic hepatitis has shown a statistically significant correlation between TPA and alanine aminotransferase (ALT). On the other hand, AFP hants' shown statistically significant variations. The reasons of the TPA increase must probably be looked for in the marked sensitivity of this protein to non neoplastic tissues in rapid regeneration, in addition to the sensitivity to neoplastic tissues. Further studies will be carried out to evaluate the usefulness of TPA to tracing possible cytolitic relapses or any resumption of activity in hepatic cirrhosis.
