['Delayed graft function (DGF) and slow graft function (SGF) due to ischemic and reperfusion injury (IRI) are common complications of deceased donor kidney transplantation. We tested whether a panel of serum and urine cytokines represent early biomarkers for DGF and SGF.', 'We collected serum and urine samples from 61 patients 48 hours posttransplantation and used a multiplex enzyme-linked immunosorbent assay (ELISA) technique to measure levels of 23 cytokines. Fourteen patients developed poor graft function (PGF), with 6 having DGF and 8 with SGF.', 'Area under receiver operation characteristics curve (AUC) demonstrated the following: serum levels of SCF (0.88) and interleukin (IL) 16 (0.74).'] Are stem cell factor , interleukin-16 , and interleukin-2 receptor alpha predictive biomarkers for delayed and slow graft function?
