Background: Due to the drastic shortage of organ donors, clinicians are increasingly considering the use of deceased after cardiac death donors (DCD). Compatible solutes like Ectoine and Hydroxyectoine are produced by extremophilic bacteria as a cell protectant to survive in harsh environments. We hypothesized that the addition of Hydroxyectoine to Histidine-Tryptophan-Ketoglutarate solution (HTK) could ameliorate cold ischemic preservation injury of DCD livers.
Material and Methods: Rat livers were harvested from male Wistar rats weighing 250–300 g. Three experimental groups (n=5 per group) were studied: (1) Controls: cold static storage in HTK for 24 h, (2) DCD: 30-min warm ischemia time and 24-h cold static storage in HTK, and (3) DCD+Hydroxyectoine: like DCD, but with 24-h cold static storage in...
