Normothermic machine preservation (NMP) of the kidney has been studied extensively during the last two decades and implemented in clinical trials. Biomarker research led to success in identifying molecules with diagnostic, predictive and therapeutic properties in chronic kidney disease. However, perfusate biomarkers and potential predictive mechanisms in NMP have not been identified yet. Twelve discarded human kidneys (<i>n</i> = 7 DBD, <i>n</i> = 5 DCD) underwent NMP for up to 24 h. Eight were perfused applying urine recirculation (URC), four with replacement of urine (UR) using Ringer's lactate. The aim of our study was to investigate biomarkers (NGAL, KIM-1, and L-FABP), cells andFrontiers in medicine801098https://www.ebi.ac.uk/biostudies/studies/S-EPMC8784871biostudies-literatureHemodynamics and Metabolic Parameters in Normothermic Kidney Preservation Are Linked With Donor Factors, Perfusate Cells, and Cytokines.PMC8784871Weissenbacher APloeg RJCoussios CCLo Faro MLFildes JEStone JPFriend PJHunter JPfalseHemodynamics and Metabolic Parameters in Normothermic Kidney Preservation Are Linked With Donor Factors, Perfusate Cells, and Cytokines.Kidney transplantation is the best renal-replacement option for most patients with end-stage renal disease.
