Hui Lin Karim Bousnina Julia S. Slagter Yitian Fang Iacopo Cristoferi Ingrid M. Garrelds A. H. Jan Danser Marlies E. J. Reinders Robert C. Minnee Martin J. Hoogduijn Clinical Transplantation ABSTRACTBackgroundHuman donor kidneys release (pro)renin, erythropoietin (EPO), active vitamin D, and urodilatin during normothermic machine perfusion (NMP). However, whether the endocrine function of donor kidneys is associated with post‐transplant kidney function is unclear.MethodsWe studied 28 donor kidneys, including seven from donation after brain death (DBD) donors and 21 from donation after circulatory death (DCD) donors. Prior to transplantation, we measured levels of (pro)renin, EPO, 1,25(OH)2D in the perfusate, and urodilatin in urine during NMP. Hormone release rates were compared between kidneys with and without delayed graft function (DGF), and correlations were assessed between hormone release rates and donor characteristics and transplant outcome, including DGF duration, serum creatinine levels at 1‐week post‐transplant, and estimated glomerular filtration rate at 1‐month post‐transplant.ResultsDBD kidneys secreted significantly less EPO and more active vitamin D than DCD kidneys. Kidneys with DGF exhibited significantly higher release rates of active vitamin D and lower release rates of urodilatin compared to those without DGF. In addition, EPO release rate was positively correlated with serum creatinine levels at 1‐week post‐transplant. Finally, urodilatin release rates were negatively correlated with DGF duration and positively correlated with urine output.ConclusionsUrodilatin release in urine and EPO and active vitamin D release in perfusate during NMP may serve as potential biomarkers for predicting early post‐transplant outcomes.Trial Registration: ClinicalTrials.gov identifier: NCT04882254 10.1111/ctr.70163 http://creativecommons.org/licenses/by-nc/4.0/ |
