  1. There were no significant differences for any of the donor and recipient characteristics by clinical outcome, including HLA mismatch and end-stage renal disease (ESRD) that was classified in three main groups: Non-immune structural mediated (polycystic kidney disease and aplastic/hypoplastic/dysplastic kidneys), Reflux (obstructive uropathy, pyelonephritis/interstitial nephritis and reflux nephropathy) and other/unknown (focal segmental glomerulosclerosis, cystinosis, hemolytic uremic syndrome, cortical necrosis, other and unknown). Class I DSA was developed in one individual in the PNR and also was found at time 0 in another individual in the PR group
