title: Trimetazidine reduces renal dysfunction by limiting the cold ischemia/reperfusion injury in autotransplanted pig kidneys.
abstract: Ischemia/reperfusion injury leads to delayed graft function, which is a major problem in kidney transplantation. This study investigated the effects of adding trimetazidine (TMZ) to the perfusate of cold-stored kidneys on the function of reperfused autotransplanted pig kidney. The left kidney was removed and cold-flushed with Euro-Collins (EC), or University of Wisconsin (UW) solutions with or without 10(-6)M TMZ and stored for 48 h at 4 degrees C. The kidneys were then autotransplanted and the contralateral kidneys were removed. Several parameters were analyzed over the 14 d after transplantation. The survival rate was 57% in pigs transplanted with kidneys cold-flushed with UW and 43% for those flushed with EC solution; it was 100% for pigs having kidneys cold-flushed with TMZ-supplemented UW and EC solutions. The functions of the transplanted kidneys were also better preserved after cold flush with TMZ-supplemented solutions than with TMZ-free solutions. Creatinine clearance was higher and the urinary excretion of trimethylamine-N-oxide and dimethylamine, used as markers of renal medulla injury, were lower in animals transplanted with kidneys cold-flushed with TMZ-supplemented solutions than with TMZ-free solutions. The cytoprotective action of TMZ also reduced interstitial and peritubular inflammation and the numbers of infiltrating mononuclear CD45+and CD3+ T cells. These results indicate that the tissue damage due to ischemia/reperfusion injury may be prevented, at least in part, by adding TMZ to preservation solutions.
