title: [Dipeptidyl-peptidase IV of human lymphocytes in patients with primary biliary cirrhosis and UDCA therapy].
abstract: Investigations concerning changes of dipeptidyl-peptidase IV-positive (DP IV+) lymphocytes in the peripheral blood (PBL) were undertaken in 22 patients with primary biliary cirrhosis (PBC) under therapy with ursodeoxycholic acid (750 mg/day). We found that 4-8 weeks after therapy beginning the number of DP IV+ PBL was raised from a low initial suppressed level of 5-12% into a range of 18-33% corresponding to that of a healthy. Concurrently liver function parameters of the patients were improved significantly. The identity of DP IV+ and CDw26+ of peripheral T-cells could be shown by combination of the cytochemical DP IV-staining with the indirect immunofluorescence of the lymphocyte marker CDw26. These results show that the UDCA-therapy in patients with PBC has a direct effect on the immune system and a positive influence on the immuno-regulative capacity.
