Background: The effects of delayed graft function on long-term kidney allograft outcomes are poorly defined among simultaneous liver and kidney transplant recipients. Methods: We analyzed data of all simultaneous liver and kidney recipients transplanted at the University of Wisconsin between 2010 and 2017. Risk factors for the development of delayed graft function, kidney graft failure, and patient mortality were outcomes of interest. Results: There were a total of 60 simultaneous liver and kidney recipients; 28 (47%) had delayed graft function. After adjustment for multiple variables, we found that pretransplant dialysis >6 weeks (hazard ratio [HR] = 5.6, 95% CI: 1.23-25.59, P = .02), pretransplant albumin <3 g/dL (HR = 5.75, 95% CI: 1.76-16.94, P = .003), and presence of pretransplant diabetes (HR = 2.5, 95% CI: 0.97-4.77, P = .05) were significantly associated with delayed graft function. Multivariate analysis showed that pretransplant albumin <3 (HR = 4.86, 95% CI: 1.07-22.02, P = .02) was associated with a higher risk of all-cause kidney allograft failure, whereas the duration of delayed graft function (HR = 1.07 per day, 95% CI: 1.01-1.14, P = .01) was associated with a higher risk of death-censored kidney allograft failure. The presence of delayed graft function was not associated with all-cause or death-censored kidney or liver allograft failure. Similarly, the presence of delayed graft function was not associated with patient mortality. Conclusion: The incidence of delayed graft function was high in simultaneous liver and kidney recipients. However, with appropriate management, delayed graft function may not have a negative impact on patient or kidney allograft survival.

ABSTRACT Introduction: The development of novel non-invasive biomarkers of kidney graft dysfunction, especially in the course of the delayed graft function period would be an important step forward in the clinical practice of kidney transplantation. Methods: We evaluated by RT-PCR the expression of miRNA-146 to -5p ribonucleic micro-acids (miRNAs) in the peripheral blood and renal tissue obtained from kidney transplant recipients who underwent a surveillance graft biopsy during the period of delayed graft function. Results: In biopsy samples, the expression of miR-146a-5p was significantly increased in the group of patients with delayed graft function (DGF) (n = 33) versus stables patients (STA) (n = 13) and patients with acute rejection (AR) (n = 9) (p = 0.008). In peripheral blood samples, a non-significant increase of miR-146a-5p expression was found in the DGF group versus STA and AR groups (p = 0.083). No significant correlation was found between levels of expression in biopsy and plasma. ROC curve analysis revealed an AUC of 0.75 (95% CI: 0.62-0.88) for the renal tissue expression and 0.67 (95% CI 0.52-0.81) for the peripheral blood expression. Conclusion: We conclude that miR-146a-5p expression has a distinct pattern in the renal tissue and perhaps in the peripheral blood in the setting of DGF. Further refinements and strategies for studies should be developed in the field of non-invasive molecular diagnosis of kidney graft dysfunction.

<b><i>Introduction:</i></b> Living donor kidney transplant (LDKT) is one of the best therapeutic options for end-stage kidney disease (ESKD). Guidelines identify different estimated glomerular filtration rate (eGFR) thresholds to determine the eligibility of donors. The aim of our study was to evaluate whether pretransplant donor eGFR was associated with kidney function in the recipient. <b><i>Methods:</i></b> We retrospectively studied LDKT recipients who received a kidney graft between September 1, 2005, and June 30, 2016 in the same transplant center in France and that had eGFR data available at 3, 12, 24, and 36 months posttransplant. <b><i>Results:</i></b> We studied 90 donor-recipient pairs. The average age at time of transplant was 51.47 ± 10.95 for donors and 43.04 ± 13.52 years for recipients. Donors’ average eGFR was 91.99 ± 15.37 mL/min/1.73 m<sup>2</sup>. Donor’s age and eGFR were significantly correlated (<i>p</i> &#x3c; 0.0001, <i>r</i><sup>2</sup> 0.023). Donor’s age and eGFR significantly correlated with recipient’s eGFR at 3, 12, and 24 months posttransplant (age: <i>p</i> &#x3c; 0.001 at all intervals; eGFR <i>p</i> = 0.001, 0.003, and 0.016, respectively); at 36 months, only donor’s age significantly correlated with recipient’s eGFR. BMI, gender match, and year of kidney transplant did not correlate with graft function. In the multivariable analyses, donor’s eGFR and donor’s age were found to be associated with graft function; correlation with eGFR was lost at 36 months; and donor’s age retained a strong correlation with graft function at all intervals (<i>p</i> &#x3c; 0.001). <b><i>Conclusions:</i></b> Donor’s eGFR and age are strong predictors of recipient’s kidney function at 3 years. We suggest that donor’s eGFR should be clinically balanced with other determinants of kidney function and in particular with age.

Abstract Background and Aims As kidney transplants are growing in absolute numbers, so are patients with failed allografts and thus potential candidates for re-transplantation. Re-transplantation is challenging due to immunological barriers, surgical difficulties and clinical complexities but it has been proven that successful second transplantation improves life expectancy over dialysis. It is important to evaluate re-transplantation outcomes since 20% of patients on the waiting list are waiting for a second graft. Our aim was to compare major clinical outcomes such as acute rejection, graft and patient survival, between patients receiving a first or a second kidney transplant. Method We performed a retrospective study, that included 1552 patients submitted to a first (N=1443, 93%) or a second kidney transplant (N=109, 7%), between January 2008 and December 2018. Patients with more than 2 grafts or multi-organ transplant were excluded. Demographic, clinical and histocompatibility characteristics of both groups were registered from our unit database and compared. Delayed graft function was defined has the need of dialysis in the first week post-transplant. All acute rejection episodes were biopsy proven, according to Banff 2017 criteria. Follow-up time was defined at 1st June 2020 for functioning grafts or at graft failure (including death with a functioning graft). Results Recipients of a second graft were significantly younger (43 ±12 vs 50 ± 13 years old, p&lt;0.001) and there were significantly fewer expanded-criteria donors in the second transplant group (31.5% vs 57.5%, p&lt;0.001). The waiting time for a second graft was longer (63±50 vs 48±29 months, p=0.011). HLA mismatch was similar for both groups but PRA was significantly higher for second KT patients (21.6±25% versus 3±9%; p&lt;0.001). All patients submitted to a second KT had thymoglobulin as induction therapy compared to 16% of the first KT group (p&lt;0.001). We found no difference in primary dysfunction or delayed graft function between groups. Acute rejection was significantly more frequent in second kidney transplant recipients (19% vs 5%, p&lt;0.001), being 10 acute cellular rejections, 7 were antibody mediated and 3 were borderline changes. For the majority of the patients (85%), acute rejection occurred in the first-year post-transplant. Death censored graft failure occurred in 236 (16.4%) patients with first kidney transplant and 25 (23%) patients with a second graft, p=0.08. Survival analysis showed similar graft survival for both groups (log-rank p=0.392). We found no difference in patients’ mortality at follow up for both groups. Conclusion Although second graft patients presented more episodes of biopsy proven acute rejection, especially at the first-year post-transplant, we found no differences in death censored graft survival or patients’ mortality for patients with a second kidney transplant. Second transplants should be offered to patients whenever feasible.

BackgroundThe recognition that metabolism and immune function are regulated by an endogenous molecular clock generating circadian rhythms suggests that the magnitude of ischemia-reperfusion and subsequent inflammation on kidney transplantation, could be affected by the time of the day. MethodsAccordingly, we evaluated 5026 first kidney transplant recipients from deceased heart-beating donors. In a cause-specific multivariable analysis, we compare delayed graft function (DGF) and graft survival according to the time of kidney clamping and declamping. Participants were divided into clamping between midnight and noon (AM clamping group, 65%) or clamping between noon and midnight (PM clamping group, 35%), and similarly, AM declamping or PM declamping (25% / 75%). ResultsDGF occurred among 550 participants (27%) with AM clamping and 339 (34%) with PM clamping (adjusted OR = 0.81, 95%CI: 0.67 to 0.98, p= 0.03). No significant association of clamping time with overall death censored graft survival was observed (HR = 0.92, 95%CI: 0.77 to 1.10, p= 0.37). No significant association of declamping time with DGF or graft survival was observed. ConclusionsClamping between midnight and noon was associated with a lower incidence of DGF whilst the declamping time was not associated with kidney graft outcomes.
