[Physical capacity of patients with liver diseases as well as its significance for therapy and evaluation].

In 50 patients with different liver diseases (20 with subsided viral hepatitis and 30 with degenerative liver damages) the serum enzyme course of SGOT, SGPT, LDH and CPK was investigated after ergometer load. The enzymes were estimated before as well as 1/2, 2, 4, 24, and 48 hours after load. 48 hours after load additionally the liver biopsy after Menghini was carried out. According to the histological findings the 20 patients with viral hepatitis were subdivided into 13 with still active and 7 with residual hepatitis as well as the 30 patients with degenerative liver damages into 15 with toxical hepatosis, 6 with fatty degeneration of the liver cells and 9 with signs of metabolic activation. Since the significant increases of enzymes could not be proved in any of the fours enzymes 1/2 to 48 hours after load we are of the opinion that the liver, independent on the kind of the lesion, better tolerates physical work. Moreover, it seems that load investigations under ergometry with estimation of the course of the serum enzymes are unsuited for the judgment of the degree of activity and the degree of cure of liver diseases, respectively.
