[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.

Prognostic significance of free radicals: mediated injury occurring in the kidney donor.

BACKGROUND: Brain death is associated with hemodynamic disturbances in systemic circulation and metabolic storm, and, thus, free radical-mediated injury to donor tissues was hypothesized. An assessment of oxidative stress in the donor and its effect on posttransplant kidney graft function comprised the scope of the study. METHODS: A prospective study was performed in 27 donors and 50 kidney transplant recipients. Sera from 27 brain-dead organ donors and preservation media were tested for malondialdehyde (MDA) and for total antioxidant status (TAS). Kidneys were preserved in University of Wisconsin-gluconate solution with machine perfusion. Mean ischemia time was 36.7+/-8 hours. Organs were transplanted to recipients on the Polish National Waiting List and posttransplant kidney function was monitored periodically. Posttransplant delayed graft function (DF) was diagnosed when a patient required at least one dialysis within first week after transplantation. Acute rejection was diagnosed clinically and confirmed with fine-needle biopsy if necessary. RESULTS: Thirty-two recipients had immediate graft function (IF), and 18 suffered from DF. MDA level in preservation solution at the end of machine perfusion was significantly higher in the DF group (52.6+/-31 vs. 25.3+/-19 micromol/L) whereas donor TAS activity was lower (1.14+/-0.2 vs. 0.97+/-0.3 mmol/mL). Patients who suffered from acute rejection received kidneys from donors with significantly higher serum MDA (66+/-73 micromol/ml vs. 23+/-49 for patients without rejection). Serum creatinine 12 to 48 months after transplantation correlated to donor- and preservation-solution MDA (P<0.006). CONCLUSIONS: Free-radical mediated injury occurring in the donor and during preservation is strictly correlated with immediate and long-term kidney function. It may also cause grafts to be prone to acute rejection.
