Background: Liver allocation in Eurotransplant (ET) is based on the MELD score. Interlaboratory MELD score differences in INR and creatinine determination have been reported. The clinical implication of this observation has not been demonstrated. Methods: MELD scores were calculated in 66 patients with liver cirrhosis using bilirubin, creatinine, and INR analyzed in six liver transplant centers. Based on allocation results of ET, patients transplanted from December 2006 to June 2007 were divided according to MELD score in four groups. For each group, the influence of the match MELD on the probability of receiving a transplant was studied (Cox proportional hazards model). Results: Laboratory-dependent significant differences in MELD score were demonstrated. Cox proportional hazards model showed a significant association between MELD score and the probability of organ allocation. The unadjusted hazard ratio for receiving a liver transplant was significantly different between group 2 and group 4 (group 2: MELD 19–24; group 4: MELD > 30). Conclusion: Laboratory-dependent significant differences in MELD score were observed between the six transplant centers. We demonstrated a significant association between the MELD score and the probability of organ allocation. The observed interlaboratory variation might yield a significant difference in organ allocation in patients with high MELD scores. [less ▲]

Vascular renal resistance (RR) during hypothermic machine perfusion (HMP) is frequently used in kidney graft quality assessment. However, the association between RR and outcome has never been prospectively validated. Prospectively collected RR values of 302 machine-perfused deceased donor kidneys of all types (standard and extended criteria donor kidneys and kidneys donated after cardiac death), transplanted without prior knowledge of these RR values, were studied. In this cohort, we determined the association between RR and delayed graft function (DGF) and 1-year graft survival. The RR (mmHg/mL/min) at the end of HMP was an independent risk factor for DGF (odds ratio 21.12 [1.03–435.0]; p = 0.048) but the predictive value of RR was low, reflected by a c-statistic of the receiver operator characteristic curve of 0.58. The RR was also found to be an independent risk factor for 1-year graft failure (hazard ratio 12.33 [1.11–136.85]; p = 0.004). Determinants of transplant outcome are multifactorial in nature and this study identifies RR as an additional parameter to take into account when evaluating graft quality and estimating the likelihood of successful outcome. However, RR as a stand-alone quality assessment tool cannot be used to predict outcome with sufficient precision. [less ▲]
