Transplantation
-
ABOi transplantation is an accepted method of expanding the kidney donor pool but there is little analysis of the protocols used. We established an ABOi programme utilising leukocyte depletion, tacrolimus, TPE and IvIg. There are few reports in the literature on the success rates of antibody removal protocols or relating to patients in whom antibody removal fails. The purpose of this study was to define the likelihood of achieving transplantation depending on ABO antibody titers. ⋯ This is the first study to demonstrate a cut off titer for entry in to the ABO incompatible program using the relationship between ABO titer and amount of TPE required to reach transplantation. We now tailor the antibody removal protocol prior to transplantation and have introduced a cut-off entry titer to the program (≤1:256), because of the unacceptable risk of exposing patients with higher titers to long-lasting immunosuppression and costly, prolonged, courses of TPE without the guarantee of successful transplantation. Patients whose ABO titer exceeds the cut-off are counselled and offered alternative routes to transplantation.

Comparative Study
Plasma neutrophil gelatinase-associated lipocalin in kidney transplantation and early renal function prediction.
This prospective observational study aimed to assess the relevance of serial postoperative plasma neutrophil gelatinase-associated lipocalin (NGAL) measurements on prediction of early renal transplant function. ⋯ pNGAL level early and accurately predicted DGF after renal transplantation. pNGAL measurements allowed monitoring of the renal function in this striking situation of ischemia-reperfusion aggression. Early identification of patients at risk of DGF, before graft lesions are consolidated, opens the field of a precise monitoring of renal injury and the impact of future protective therapeutics.
