[en] Background. Retrospective evidence suggests that lactate dehydrogenase, aspartate aminotransferase, total
glutathione-S-transferase (GST), alanine-aminopeptidase, N-acetyl- -D-glucosaminidase (NAG), and hearttype
fatty acid binding protein (H-FABP) measured during kidney machine perfusion (MP) could have predictive
value for posttransplant outcome. However, these data may be biased due to organ discard based on biomarker
measurements, and previous analyses were not adjusted for likely confounding factors.Noreliable prospective evidence
has been available so far. Nevertheless, some centers already use these biomarkers to aid decisions on accepting or
discarding a donor kidney.
Methods. From 306 deceased-donor kidneys donated after brain death or controlled cardiac death and included in an
international randomized controlled trial, these six biomarkers were measured in the MP perfusate. In this unselected
prospective data set, we tested whether concentrations were associated with delayed graft function, primary nonfunction,
and graft survival. Multivariate regression models investigated whether the biomarkers remained independent
predictors when adjusted for relevant confounding factors.
Results. GST, NAG, and H-FABP were independent predictors of delayed graft function but not of primary nonfunction
and graft survival. Lactate dehydrogenase, aspartate aminotransferase, and alanine-aminopeptidase had no independent
prognostic potential for any of the endpoints. Perfusate biomarker concentrations had no relevant correlation
with cold ischemic time or renal vascular resistance on the pump.
Conclusions. Increased GST, NAG, or H-FABP concentrations during MP are an indication to adjust posttransplant
recipient management. However, this study shows for the first time that perfusate biomarker measurements should not
lead to kidney discard.
