[Current status of liver transplantation].

The authors present current status of liver transplantation (LTx) in Poland. Till 2004, 845 LTx were performed: 604 in adults and 241 in children; 71 of them were the living donor LTx. Post-inflammatory cirrhosis in adults and biliary atresia in children were the most common indications for LTx. The results of LTx in Poland are good and comparable with the results published by other centers. The number of available cadaveric grafts is growing and in 2004 achieved an index of harvesting as high as 14,7 per million people.

[Technical progress in liver transplantation].

Throughout the history of liver transplantation many improvements have been made in the field of surgical technique. The technical progress improved results of liver transplantation; the split liver transplantation and living donor liver transplantation increased the number of cadaveric grafts, expanding primary the pediatric and later the adult liver graft pool. The authors present most of current methods of liver transplantation: orthotopic liver transplantation with or without preservation, of the inferior vena cava, "domino" liver transplantation, split liver transplantation, auxiliary liver transplantation and living donor liver transplantation.

Clinical significance of arginase after liver transplantation.

Liver graft function after transplantation is dependent on ischemia-reperfusion injury, toxicity of drugs (immunosuppression, antibiotics and other) and transplant rejection. Although routinely monitored with enzymatic tests (AST, ALT, GGT, ALP), bilirubin and coagulation parameters, differentiation between these pathologies is hardly possible without liver biopsy. Arginase (3.5.3.1) mostly exists in the liver and in trace amounts in extra-hepatic tissue. Thus, we hypothesized that activity of arginase could be a more specific test of liver function. Sera of 32 liver transplant recipients were tested for AST, ALT, ATIII, bilirubin and arginase. Samples were obtained daily in first 2 weeks after LTx and weekly afterwards. Correlation of arginase activity with other liver function markers was calculated. Serum arginase peaked at day 1 post LTx (mean 64,6+/-91 IU/L), and decreased more rapidly than other tests if good liver function was observed. The values showed strong and significant correlation with AST and ALT activities (Pearsons R 0,65 and 0,47 respectively). We conclude that activity of arginase in the serum is an exact test of liver function.
