<b><i>Purpose:</i></b> This study aimed to analyze our data on delayed graft function (DGF) and to identify associated factors. <b><i>Methods:</i></b> This is a retrospective case-control study of all patients transplanted in our center over a period of 11 years (January 1, 2003, to December 31, 2014) comparing patients with immediate graft function (<i>n</i> = 332) to those with DGF (<i>n</i> = 165). DGF was defined as the need for hemodialysis within the first 7 days after transplantation. Donor and recipient characteristics as well as procedural factors were compared by univariate and multivariate logistic regression analyses. <b><i>Results:</i></b> Overall, 33% of patients had DGF. The rate of DGF declined from 2003 to 2011. In cases with DGF, donors and recipients were significantly older (<i>p</i> = 0.004 and <i>p</i> = 0.005, respectively), had longer cold ischemia times (<i>p</i> = 0.039), more revision surgeries (<i>p</i> &#x3c; 0.001), and more HLA mismatches (<i>p</i> = 0.001), especially in the DR locus (<i>p</i> = 0.002). Neither donor nor recipient gender, waiting time, nor CMV status had any influence. In multivariable analysis, significant risk factors were ischemia time and mismatches at the HLA-DR loci. <b><i>Conclusions:</i></b> DGF is a common complication in renal transplantation which occurred in 33% of our cases. Important factors identified were donor and recipient age, ischemia time, HLA mismatching, and revision surgery.

Introduction: Delayed graft function (DGF), defined as the needfor dialysis during the first week after renal transplantation, is animportant adverse clinical outcome. A previous model relied on16 variables to quantify the risk of DGF, thereby undermining itsclinical usefulness. We explored the possibility of developing asimpler, equally accurate and more user-friendly paradigm forrenal transplant recipients from deceased donors.Methods: Logistic regression analyses addressed the occurrenceof DGF in 532 renal transplant recipients from deceased donors.Predictors consisted of recipient age, gender, race, weight, numberof HLA-A, HLA-B and HLA-DR mismatches, maximum andlast titre of panel reactive antibodies, donor age and cold ischemiatime. Accuracy was quantified with the area under the curve. Twohundred bootstrap resamples were used for internal validation.Results: Delayed graft function occurred in 103 patients (19.4%).Recipient weight (p < 0.001), panel of reactive antibodies (p < 0.001),donor age (p < 0.001), cold ischemia time (p = 0.005) and HLADRmismatches (p = 0.05) represented independent predictors.The multivariable nomogram relying on 6 predictors was 74.3%accurate in predicting the probability of DGF.Conclusion: Our simple and user-friendly model requires 6 variablesand is at least equally accurate (74%) to the previous nomogram(71%). We demonstrate that DGF can be accurately predictedin different populations with this new model.Introduction : La reprise retardée de la fonction (RRF) du greffon,définie comme le besoin de recourir à la dialyse pendant la premièresemaine suivant une transplantation rénale, est une issueclinique indésirable importante. Un modèle proposé antérieurementreposait sur 16 variables pour quantifier le risque de RRF,diminuant ainsi son utilité clinique. Nous avons exploré la possibilitéd’élaborer un paradigme simplifié et plus convivial tout enétant tout aussi précis pour les receveurs de greffons rénauxprovenant de donneurs décédés.Méthodologie : À l’aide d’analyses de régression logistique, nousavons étudié la survenue de la RRF du greffon chez 532 receveursde greffons rénaux provenant de donneurs décédés. Les facteursde prédiction comprenaient l’âge, le sexe, la race et le poids dureceveur et le nombre de non-concordance des phénotypes HLAA,HLA-B et HLA-DR, le titre maximal et le dernier titre d’anticorpsréactifs, l’âge du donneur et la période d’ischémie froide. L’exactitudea été quantifiée par la mesure de la surface sous la courbe. Deuxcents rééchantillonnages par auto-amorçage ont servi à la validationinterne.Résultats : Une reprise retardée de la fonction a été observée chez103 patients (19,4 %). Le poids du receveur (p < 0,001), les anticorpsréactifs (p < 0,001), l’âge du donneur (p < 0,001), la périoded’ischémie froide (p = 0,005) et la non-concordance des phénotypesHLA-DR (p = 0,05) constituaient des facteurs de prédictionindépendants. Le nomogramme multivarié reposant sur 6 facteursde prédiction a permis de prédire avec une exactitude de 74,3 %la probabilité de RRF.Conclusion : Notre modèle simple et convivial nécessite 6 va riableset est au moins tout aussi exact (74 %) que le nomogramme antérieur(71 %). La RRF peut être prévue avec exactitude dans différentespopulations à l’aide ce nouveau modèle, tel que nous en faisonsla démonstration.

Abstract Background Rocuronium can be used in patients with severe renal failure (creatinine clearance <30 ml/min) but the duration of muscle relaxation is longer and results in an increased risk of postoperative residual curarization. Rocuronium can be antagonized by sugammadex but the elimination of the complex they made (rocuronium-sugammadex complex) varies according to the renal function. Two case reports/series reported the use of rocuronium – sugammadex complex during renal transplantation. This retrospective case-control study aimed to investigate the effects of rocuronium – sugammadex, used during the renal transplantation, on transplanted kidney function.Methods We analyzed 113 medical records of patients undergoing kidney transplantation from January 2015 to December 2018. 47 medical records were excluded because they did not report the administration of rocuronium + sugammadex or cisatracurium + neostigmine during the transplantation. For each medical records the following data were recorded the characteristics of patients and of kidney donor. Blood creatinine, blood urea, blood sodium, blood potassium, blood calcium levels were collected at the day before the surgery, the day of surgery, after 6 hours (hrs), 12 hrs, 24 hrs, 48 hrs and 72 hrs. Diuresis, urinary sodium and urinary potassium levels were collected at the day of surgery, after 6 hrs, 12 hrs, 24 hrs, 48 hrs and 72 hrs. Results We collected data from 66 medical reports. Blood creatinine levels at 6 hrs, 12 hrs and 24 hrs were significantly lower in roc + sug group than cis + neo group (crea 6 hrs =0.05, crea 12 hrs p=0.038, crea 24 hrs p= 0.049). Blood urea levels for 24 hrs after the transplantation were significantly lower in in roc + sug group than cis + neo group (urea 0 hrs p=0.025, urea 6 hrs p= 0.011, urea 12 hrs p=0.03, urea 24 hrs p=0.011). We found no statistically significant differences in blood sodium, blood potassium, blood calcium, diuresis, urinary sodium, urinary potassium levels before and after the transplantation.Conclusions In this retrospective case-control study, the use of rocuronium and sugammadex during the renal transplant surgery did not affect the recovery of the graft function during the first week after the transplantation.

Rocuronium can be antagonized by sugammadex, but the elimination of the complex they make (rocuronium-sugammadex complex) varies according to the renal function.

This retrospective case-control study aims to investigate the effects of rocuronium-sugammadex, used during renal transplantation, on transplanted kidney function. Methods: We analyzed 113 medical records of patients undergoing kidney transplantation from January 2015 to December 2018. Forty-seven medical records were excluded because they did not report the administration of rocuronium + sugammadex (roc + sug) or cisatracurium + neostigmine (cis + neo) during the transplantation. The demographics of patients and donors were collected along with the following data: blood urea and creatinine, serum and urinary electrolytes, and diuresis. Marginal, single or double kidney transplantations, Karpinsky score and histologic evaluation of transplanted kidney were collected. Results: We finally collected data from 66 medical reports from January 2015 to December 2018. Blood creatinine levels at 6 hrs, 12 hrs and 24 hrs were significantly lower in the roc + sug group than in the cis + neo group (crea 6 hrs =0.05, crea 12 hrs p=0.038, crea 24 hrs p= 0.049). Blood urea levels for 24 hrs after transplantation were significantly lower in the roc + sug group than in the cis + neo group (urea 0 hrs p=0.025, urea 6 hrs p= 0.011, urea 12 hrs p=0.03, urea 24 hrs p=0.011). We found no statistically significant differences in blood sodium, blood potassium, blood calcium, diuresis, urinary sodium, or urinary potassium levels before and after transplantation. Conclusions: In this retrospective case-control study, the use of rocuronium and sugammadex during renal transplant surgery did not affect the recovery of the graft function during the first week after transplantation.
