Effect of High-Dose Erythropoietin on Graft Function after Kidney Transplantation: A Randomized, Double-Blind Clinical Trial

Summary Background and objectives Delayed graft function (DGF) is associated with adverse long-term outcomes after deceased-donor kidney (DDK) transplantation. Ischemia-reperfusion injury plays a crucial role in the development of DGF. On the basis of promising animal data, this study evaluated any potential benefits of erythropoietin-alfa (EPO-a)givenintra-arteriallyatthetimeofreperfusionofrenalallograftonthedegreeofallograftfunction,aswellas tubular cell injury measured by urinary biomarkers in the early post-transplant period. Design, setting, participants, & measurements A prospective, randomized, double-blind, placebo-controlled clinical trial was conducted to evaluate the influence of EPO-a administered intraoperatively on the outcomes of DDK transplantations performed at the study center between March 2007 and July 2009. ResultsSeventy-two patients wererandomlyassigned to EPO-a(n=36)orplacebo(n=36).The incidencesof DGF, slow graft function, and immediate graft function did not significantly differ between the treatment and control groups (41.7% versus 47.2%, 25.0% versus 36.1%, and 33.3% versus 16.7%, respectively; P=0.24). The groups had similar levels of urinary biomarkers, including neutrophil gelatinase-associated lipocalin and IL-18 at multiple times points soon after transplantation; urinary output during the first 3 postoperative days; 1-month renal function; and BP readings, hemoglobin, and adverse effects during the first month.
