Abstract:
Die Transplantation marginaler Organe infolge der prolongierten kalter Ischämie ist eine bedeutende therapeutische Option, die zwar mit der Reduktion der Mortalität auf der Warteliste einhergeht, dennoch eine Transplantatdysfunktion bewirken kann. Vor diesem Hintergrund ist naheliegend, dass Anstrengungen unternommen werden sollen, durch eine prädiktive analytische Methode eine Strategie zu entwickeln, um die Nutzbarmachung der marginalen Organe zu erhöhen und gleichzeitig die absolut kritischen...     »
Translated abstract:
Aim: Transplantation of extended donor criteria organs due to prolonged cold ischemia is one of the major options to increase the use of such organs and therefore reduces the mortality. However this may lead to dysfunction of the organ. Therefore its necessary to develop a predictive analytic method in order to identify such extended donor organs and exclude them from transplantation. Method: The animal studies were approved by the government of Bavaria, Munich. We used special LEWIS-(RT)-rats which were divided into three groups (n=4), depending on cold ischemia time and loss of ATP production after 2, 4 and 8 hours (post explantationem). The evaluation of the ATP production and histopathology was limited to such animals where the anhepatic phase was <20 minutes and the transplantation time <60min. For statistical analysis we used a program called software R, Version 2.12.2 (Development Core Team). The significance was 5 %. Result: There was an inverse correlation between the ATP/protein date and the histopathology of the ischemia-reperfusion-injury (o=0,003). Discussion: We evaluated the degree of the ischemia-reperfusion injury by comparing the mitochondrial permeability and the histopathology. By having a prolonged ischemia of 8 hours, the evaluation of the ATP/protein production was more sensitive than the histopathology. Thus this fact could be used in order to obtain a score that could identify extended donor organs.
