title: Consideration of potential immunological problems in the application of xenogenic hybrid liver support.
abstract: Hybrid liver support systems (LSS) for the use of pig liver cells are under development for extracorporeal therapy of acute liver failure and for bridging to liver transplantation. A literature overview about possible immunological side effects of a clinical application is given. The data summarised from experimental studies and those clinical applications of porcine cells reported so far, suggest that clinical use of LSS utilising porcine cells and an immuno-isolation membrane should not be compromised by severe immunological complications. The reported data suggest that clinical application should be conducted in conjunction with carefully planned immunological monitoring. Only after such applications of LSS have been carried out and further data have been evaluated, might one be able to judge the immunological consequences of broader application of hybrid liver support.
