Abstract
BACKGROUND Pancreas transplant biopsy practices for the diagnosis of rejection or other pathologies are not well described. METHODS We conducted a survey of staff at US pancreas transplant programs (March 22, 2022, to August 22, 2022) to assess current program practices and perceptions about the utility and challenges in the performance and interpretation of pancreas allograft biopsies. RESULTS Respondents represented 65% (76/117) of active adult pancreas transplant programs, capturing 66% of recent pancreas transplant volume in the United States. Participants were most often nephrologists (52%), followed by surgeons (46%), and other staff (4%). Pancreas allograft biopsies were performed mostly by interventional radiologists (74%), followed by surgeons (11%), nephrologists (8%), and gastroenterologists (1%). Limitations in the radiologist's or biopsy performer's comfort level or expertise to safely perform a biopsy, or to obtain sufficient/adequate samples were the two most common challenges with pancreas transplant biopsies. Pancreas transplant biopsies were read by local pathologists at a majority (86%) of centers. Challenges reported with pancreas biopsy interpretation included poor reliability, lack of reporting of C4d staining, lack of reporting of rejection grading, and inconclusive interpretation of the biopsy. Staff at a third of responding programs (34%) stated that they rarely or never perform pancreas allograft biopsies and treat presumed rejection empirically. CONCLUSIONS This national survey identified significant variation in clinical practices related to pancreas allograft biopsies and potential barriers to pancreas transplant utilization across the United States. Consideration of strategies to improve program experience with percutaneous pancreas biopsy and to support optimal management of pancreas allograft rejection informed by histology is warranted.

Abstract
BACKGROUND LCPT (Envarsus XR®) is a common once-daily, extended-release oral tacrolimus formulation used in kidney transplantation. However, there are minimal evidence-based recommendations regarding optimal dosing and treatment in the de novo and conversion settings. MATERIAL AND METHODS Using Delphi methodology, 12 kidney transplantation experts with LCPT experience reviewed available data to determine potential consensus topics. Key statements regarding LCPT use were generated and disseminated to the panel in an online Delphi survey. Statements were either accepted, revised, or rejected based on the level of consensus, perceived strength of evidence, and alignment with clinical practice. Consensus was defined a priori as ≥75% agreement. RESULTS Twenty-three statements were generated: 14 focused on de novo LCPT use and 9 on general administration or LCPT conversion use. After 2 rounds, consensus was achieved for 11/14 of the former and 7/9 of the latter statements. In a de novo setting, LCPT was recognized as a first-line option based on its safety and efficacy compared to immediate-release tacrolimus. In particular, African Americans and rapid metabolizer populations were identified as preferred for first-line LCPT therapy. In a conversion setting, full consensus was achieved for converting to LCPT to address neurological adverse effects related to immediate-release tacrolimus and for the time required (approximately 7 days) for steady-state LCPT trough levels to be reached. CONCLUSIONS When randomized clinical trials do not replicate current utilization patterns, the Delphi process can successfully generate consensus statements by expert clinicians to inform clinical decision-making for the use of LCPT in kidney transplant recipients.

Abstract
Key Points
Posoleucel was generally safe, well tolerated, and associated with a greater reduction of BK viremia compared with placebo.BK viremia reduction occurred coincident with an increase in the circulating frequency of BK virus–specific T cells in posoleucel recipients.The presence and persistence of posoleucel was confirmed by T-cell receptor variable β sequencing.
Background
Kidney transplant recipients with BK virus infection are at risk of developing BK virus–associated nephropathy, allograft rejection, and subsequent graft loss. There are no approved treatments for BK virus infection. Posoleucel is an off-the-shelf, allogeneic, multivirus-specific T-cell investigational therapy targeting BK virus, as well as five other opportunistic viruses: adenovirus, cytomegalovirus, Epstein–Barr virus, human herpesvirus 6, and John Cunningham virus.
Methods
In this phase 2, double-blind study, kidney transplant recipients with BK viremia were randomized 1:1:1 to receive posoleucel weekly for 3 weeks and then every 14 days (bi-weekly dosing) or every 28 days (monthly dosing) or placebo for 12 weeks. Participants were followed for 12 weeks after completing treatment. The primary objective was safety; the secondary objective was plasma BK viral load reduction.
Results
Sixty-one participants were randomized and dosed. Baseline characteristics were similar across groups. No deaths, graft-versus-host disease, or cytokine release syndrome occurred. The proportion of patients who had adverse events (AEs) judged by the investigators to be treatment-related was slightly lower in recipients of posoleucel: 20% (4 of 20 patients) and 18% (4 of 22) in those infused on a bi-weekly and monthly schedule, respectively, and 26% (5 of 19) in placebo recipients. None of the grade 3–4 AEs or serious AEs in any group were deemed treatment-related. No deaths, graft-versus-host disease, or cytokine release syndrome occurred. Three participants had allograft rejection, but none were deemed treatment-related by investigators. In posoleucel recipients, BK viremia reduction was associated with an increase in the circulating frequency of BK virus–specific T cells, and the presence and persistence of posoleucel was confirmed by T-cell receptor sequencing.
Conclusions
Posoleucel was generally safe, well tolerated, and associated with a larger reduction of BK viremia compared with placebo. Limitations of this study include the relatively short duration of follow-up and lack of power to detect significant differences in clinical outcomes.

Abstract
RATIONALE & OBJECTIVE Kidney transplant patients with failing allografts have a physical and psychological symptom burden as well as high morbidity and mortality. Palliative care is underutilized in this vulnerable population. We described kidney transplant clinicians' perceptions of palliative care to delineate their perceived barriers to and facilitators of providing palliative care to this population. STUDY DESIGN National explanatory sequential mixed methods study including an online survey and semistructured interviews. SETTING & PARTICIPANTS Kidney transplant clinicians in the United States surveyed and interviewed from October 2021 to March 2022. ANALYTICAL APPROACH Descriptive summary of survey responses, thematic analysis of qualitative interviews, and mixed methods integration of data. RESULTS A total of 149 clinicians completed the survey, and 19 completed the subsequent interviews. Over 90% of respondents agreed that palliative care can be helpful for patients with a failing kidney allograft. However, 46% of respondents disagreed that all patients with failing allografts benefit from palliative care, and two-thirds thought that patients would not want serious illness conversations. More than 90% of clinicians expressed concern that transplant patients and caregivers would feel scared or anxious if offered palliative care. The interviews identified three main themes: (1) transplant clinicians' unique sense of personal and professional responsibility was a barrier to palliative care engagement, (2) clinicians' uncertainty regarding the timing of palliative care collaboration would lead to delayed referral, and (3) clinicians felt challenged by factors related to patients' cultural backgrounds and identities, such as language differences. Many comments reflected an unfamiliarity with the broad scope of palliative care beyond end-of-life care. LIMITATIONS Potential selection bias. CONCLUSIONS Our study suggests that multiple barriers related to patients, clinicians, health systems, and health policies may pose challenges to the delivery of palliative care for patients with failing kidney transplants. This study illustrates the urgent need for ongoing efforts to optimize palliative care delivery models dedicated to kidney transplant patients, their families, and the clinicians who serve them. PLAIN-LANGUAGE SUMMARY Kidney transplant patients experience physical and psychological suffering in the context of their illnesses that may be amenable to palliative care. However, palliative care is often underutilized in this population. In this mixed-methods study, we surveyed 149 clinicians across the United States, and 19 of them completed semistructured interviews. Our study results demonstrate that several patient, clinician, system, and policy factors need to be addressed to improve palliative care delivery to this vulnerable population.

Abstract
Atypical antiglomerular basement membrane (anti-GBM) nephritis can be defined as linear GBM staining for monotypic or polytypic immunoglobulin (Ig) by immunofluorescence (IF) without a diffuse crescentic pattern. We describe the clinicopathologic features of 6 patients (18 biopsies) in this first series of recurrent atypical anti-GBM nephritis after kidney transplantation. Recurrent glomerulonephritis occurred at a mean of 3.8 months posttransplant (range 1-7 months). Three index biopsies were for clinical indication, and 3 were protocol biopsies. Glomerular histologic changes were mild, with 2 showing segmental endocapillary hypercellularity, 1 focal glomerular microangiopathy, and the others no significant glomerular histologic changes. All 6 allografts showed monotypic linear glomerular Ig staining by IF: IgG kappa (n = 2), IgG lambda, IgA kappa, IgA lambda, and IgM lambda. Follow-up biopsies were available for 5 patients and showed similar histologic and IF findings without evidence of significant progression. No patients had detectable serum anti-GBM antibody or monoclonal proteins. The mean serum creatinine level on follow-up (24-62 months posttransplant) was 1.8 (range 0.93-2.77) mg/dL; no grafts were lost to recurrent disease. This series demonstrates that monotypic atypical anti-GBM recurs in the allograft and supports the idea that this disease is due to a circulating monoclonal protein.

Abstract
Despite the continued improvements in pancreas transplant outcomes in recent decades, a subset of recipients experience graft failure and can experience substantial morbidity and mortality. Here, we summarize what is known about the failed pancreas allograft and what factors are important for consideration of retransplantation. The current definition of pancreas allograft failure and its challenges for the transplant community are explored. The impacts of a failed pancreas allograft are presented, including patient survival and resultant morbidities. The signs, symptoms, and medical and surgical management of a failed pancreas allograft are described, whereas the options and consequences of immunosuppression withdrawal are reviewed. Medical and surgical factors necessary for successful retransplant candidacy are detailed with emphasis on how well-selected patients may achieve excellent retransplant outcomes. To achieve substantial medical mitigation and even pancreas retransplantation, patients with a failed pancreas allograft warrant special attention to their residual renal, cardiovascular, and pulmonary function. Future studies of the failed pancreas allograft will require improved reporting of graft failure from transplant centers and continued investigation from experienced centers.

Abstract
The early detection of acute rejection in the allograft is important as it provides an opportunity for timely therapeutic intervention in order to preserve graft function and achieve longer graft survival. Donor-derived cell-free DNA (dd-cfDNA) has emerged as a new biomarker in the field of kidney transplantation. In this review, we used data from various studies to examine the role of dd-cfDNA in comparison to creatinine and donor-specific antibodies in the early detection of transplant rejection. We also reviewed the use of dd-cfDNA in other organ transplants as well as the challenges and potential future direction for dd-cfDNA as a diagnostic tool.

Abstract
BACKGROUND The modified Oxford classification mesangial and endocapillary hypercellularity, segmental sclerosis, interstitial fibrosis/tubular atrophy, and the presence of crescents (MEST-C) of immunoglobulin A nephropathy (IgAN) was recently shown to be a predictor of graft failure in Asians with recurrent IgAN. We aimed to validate these findings in a cohort from North American centers participating in the Banff Recurrent Glomerulopathies Working Group. METHODS We examined 171 transplant recipients with end-stage kidney disease because of IgAN; 100 of them with biopsy-proven recurrent IgAN (57 of them had complete MEST-C scores) and 71 with no recurrence. RESULTS IgAN recurrence, which was associated with younger age at transplantation ( P = 0.012), strongly increased the risk of death-censored graft failure (adjusted hazard ratio, 5.10 [95% confidence interval (CI), 2.26-11.51]; P < 0.001). Higher MEST-C score sum was associated with death-censored graft failure (adjusted hazard ratio, 8.57 [95% CI, 1.23-59.85; P = 0.03] and 61.32 [95% CI, 4.82-779.89; P = 0.002] for score sums 2-3 and 4-5 versus 0, respectively), and so were the single components endocapillary hypercellularity, interstitial fibrosis/tubular atrophy, and crescents ( P < 0.05 each). Overall, most of the pooled adjusted hazard ratio estimates associated with each MEST-C component were consistent with those from the Asian cohort (heterogeneity I2 close to 0%, and P > 0.05). CONCLUSIONS Our findings may validate the prognostic usefulness of the Oxford classification for recurrent IgAN and support the inclusion of the MEST-C score in allograft biopsies diagnostic reports.

Abstract
Despite the advances in immunosuppressive medications, antibody-mediated rejection (AMR) continues to be a major cause of kidney allograft failure and remains a barrier to improving long-term allograft survival. Recently, there have been significant advances in the understanding of the pathophysiological process of AMR, along with the development of new therapeutic options. Additionally, surveillance protocols with donor-derived cell-free DNA and gene profile testing have been established, leading to the early detection of AMR. A multitude of clinical trials are ongoing, opening numerous opportunities for improving outcome in kidney transplant recipients. In this brief review, we discuss the emerging therapies for managing both active and chronic active AMR and highlight the ongoing clinical trials.

Abstract
BACKGROUND Kidney transplantation remains the best available treatment for end-stage renal disease. However, promoting graft longevity and preventing allosensitization requires strict adherence with a stringent immunosuppression regimen. The COVID-19 pandemic has offered new challenges for kidney transplant patients and many transplant centers are denying transplantation to unvaccinated patients. The aim of this study was to evaluate whether unvaccinated patients had inferior adherence after kidney transplantation along with a reduction in graft survival. STUDY DESIGN Patients undergoing a deceased donor kidney transplantation at a single academic medical center from February 2021 to May 2022 were retrospectively reviewed. February 2021 was chosen as the start date for record review because it was 3 months after the first COVID-19 vaccination was authorized for emergency use. Patients were considered to be vaccinated if they received at least 1 dose of any mRNA vaccine by their transplantation date. RESULTS Of the 301 patients who met study criteria, 234 were vaccinated and 67 were unvaccinated. Cohorts stratified by vaccination status were well matched. Younger age was an independent risk factor for nonvaccination. Interestingly, unvaccinated patients had worse postoperative adherence with a greater average number of missed postoperative clinic visits (p = 0.03) and a strong trend toward missing 3 or more postoperative clinic visits (p = 0.07). Finally, unvaccinated patients had statistically more subtherapeutic tacrolimus troughs (p = 0.01). CONCLUSIONS Patients not vaccinated against COVID-19 had higher rate of postoperative nonadherence in key areas of immunosuppression monitoring and clinic visit attendance. Providers should be cognizant that an unvaccinated status may be a harbinger for poor adherence; therefore, stricter strategies for patient outreach are critical to ensure graft success in this vulnerable patient population.

Abstract
The management of failing kidney allograft and transition of care to general nephrologists (GN) remain a complex process. The Kidney Pancreas Community of Practice (KPCOP) Failing Allograft Workgroup designed and distributed a survey to GN between May and September 2021. Participants were invited via mail and email invitations. There were 103 respondents with primarily adult nephrology practices, of whom 41% had an academic affiliation. More than 60% reported listing for a second kidney as the most important concern in caring for patients with a failing allograft, followed by immunosuppression management (46%) and risk of mortality (38%), while resistant anemia was considered less of a concern. For the initial approach to immunosuppression reduction, 60% stop antimetabolites first, and 26% defer to the transplant nephrologist. Communicating with transplant centers about immunosuppression cessation was reported to occur always by 60%, and sometimes by 29%, while 12% reported making the decision independently. Nephrologists with academic appointments communicate with transplant providers more than private nephrologists (74% vs. 49%, p = 0.015). There are heterogeneous approaches to the care of patients with a failing allograft. Efforts to strengthen transitions of care and to develop practical practice guidelines are needed to improve the outcomes of this vulnerable population.

Abstract
Importance While the COVID-19 pandemic enters a new phase and the proportion of individuals with a previous COVID-19 diagnosis increases, the national patterns in kidney use and medium-term kidney transplant (KT) outcomes among patients receiving kidneys from active or resolved COVID-19-positive donors remain unknown. Objective To evaluate the patterns in kidney use and KT outcomes among adult recipients of kidneys from deceased donors with active or resolved COVID-19. Design, Setting, and Participants This retrospective cohort study was conducted using national US transplant registry data from 35 851 deceased donors (71 334 kidneys) and 45 912 adult patients who received KTs from March 1, 2020, to March 30, 2023. Exposure The exposure was donor SARS-CoV-2 nucleic acid amplification test (NAT) results, with positive NAT results within 7 days before procurement defined as active COVID-19 and positive NAT results 1 week (>7 days) before procurement defined as resolved COVID-19. Main Outcomes and Measures Primary outcomes were kidney nonuse, all-cause kidney graft failure, and all-cause patient death. Secondary outcomes were acute rejection (ie, rejection in the first 6 months after KT), transplant hospitalization length of stay (LOS), and delayed graft function (DGF). Multivariable logistic regression analyses were performed for kidney nonuse, rejection, and DGF; multivariable linear regression analyses were performed for LOS; and multivariable Cox regression analyses were performed for graft failure and all-cause death. All models were adjusted for inverse probability treatment weighting. Results Among 35 851 deceased donors, the mean (SD) age was 42.5 (15.3) years; 22 319 (62.3%) were men and 23 992 (66.9%) were White. Among 45 912 recipients, the mean (SD) age was 54.3 (13.2) years; 27 952 (60.9%) were men and 15 349 (33.4%) were Black. The likelihood of nonuse of kidneys from active or resolved COVID-19-positive donors decreased over time. Overall, kidneys from active COVID-19-positive donors (adjusted odds ratio [AOR], 1.55; 95% CI, 1.38-1.76) and kidneys from resolved COVID-19-positive donors (AOR, 1.31; 95% CI, 1.16-1.48) had a higher likelihood of nonuse compared with kidneys from COVID-19-negative donors. From 2020 to 2022, kidneys from active COVID-19-positive donors (2020: AOR, 11.26 [95% CI, 2.29-55.38]; 2021: AOR, 2.09 [95% CI, 1.58-2.79]; 2022: AOR, 1.47 [95% CI, 1.28-1.70]) had a higher likelihood of nonuse compared with kidneys from donors without COVID-19. Kidneys from resolved COVID-19-positive donors had a higher likelihood of nonuse in 2020 (AOR, 3.87; 95% CI, 1.26-11.90) and 2021 (AOR, 1.94; 95% CI, 1.54-2.45) but not in 2022 (AOR, 1.09; 95% CI, 0.94-1.28). In 2023, kidneys from both active COVID-19-positive donors (AOR, 1.07; 95% CI, 0.75-1.63) and resolved COVID-19-positive donors (AOR, 1.18; 95% CI, 0.80-1.73) were not associated with higher odds of nonuse. No higher risk of graft failure or death was found in patients receiving kidneys from active COVID-19-positive donors (graft failure: adjusted hazard ratio [AHR], 1.03 [95% CI, 0.78-1.37]; patient death: AHR, 1.17 [95% CI, 0.84-1.66]) or resolved COVID-19-positive donors (graft failure: AHR, 1.10 [95% CI, 0.88-1.39]; patient death: AHR, 0.95 [95% CI, 0.70-1.28]). Donor COVID-19 positivity was not associated with longer LOS, higher risk of acute rejection, or higher risk of DGF. Conclusions and Relevance In this cohort study, the likelihood of nonuse of kidneys from COVID-19-positive donors decreased over time, and donor COVID-19 positivity was not associated with worse KT outcomes within 2 years after transplant. These findings suggest that the use of kidneys from donors with active or resolved COVID-19 is safe in the medium term; further research is needed to assess longer-term transplant outcomes.

Abstract
To determine the effect of donor hepatitis C virus (HCV) infection on kidney transplant (KT) outcomes in the era of direct-acting antiviral (DAA) medications, we examined 68,087 HCV-negative KT recipients from a deceased donor between March 2015 and May 2021. A Cox regression analysis was used to estimate adjusted hazard ratios (aHRs) of KT failure, incorporating inverse probability of treatment weighting to control for patient selection to receive an HCV-positive kidney (either nucleic acid amplification test positive [NAT+, n = 2331] or antibody positive (Ab+)/NAT- [n = 1826]) based on recipient characteristics. Compared with kidney from HCV-negative donors, those from Ab+/NAT- (aHR = 0.91; 95% confidence interval [CI], 0.75-1.10) and HCV NAT+ (aHR = 0.89; 95% CI, 0.73-1.08) donors were not associated with an increased risk of KT failure over 3 years after transplant. Moreover, HCV NAT+ kidneys were associated with a higher 1-year estimated glomerular filtration (63.0 vs 61.0 mL/min/1.73 m2, P = .007) and lower risk of delayed graft function (aOR = 0.76; 95% CI, 0.68-0.84) compared with HCV-negative kidneys. Our findings suggest that donor HCV positivity is not associated with an elevated risk of graft failure. The inclusion of donor HCV status in the Kidney Donor Risk Index may no longer be appropriate in contemporary practice.

Abstract
BACKGROUND In context of increasing complexity and risk of deceased kidney donors and transplant recipients, the impact of center volume (CV) on the outcomes of high-risk kidney transplants(KT) has not been well determined. METHODS We examined the association of CV and outcomes among 285 U.S. transplant centers from 2000-2016. High-risk KT were defined as recipient age ≥ 70 years, body mass index (BMI) ≥ 35 kg/m2, receiving kidneys from donors with kidney donor profile index(KDPI) ≥ 85%, acute kidney injury(AKI), hepatitisC + . Average annual CV for the specific-high-risk KT categorized in tertiles. Death-Censored-Graft-Loss(DCGL) and death at 3 months, 1, 5, and 10 years were compared between CV tertiles using Cox-regression models. RESULTS Two hundred fifty thousand five hundred seventy-four KT were analyzed. Compared to high CV, recipients with BMI ≥ 35 kg/m2 had higher risk of DCGL in low CV(aHR = 1.11,95%CI = 1.03-1.19) at 10 years; recipients with age ≥ 70 years had higher risk of death in low CV(aHR = 1.07,95%CI = 1.01-14) at 10 years. There was no difference of DCGL or death in low CV for donors with KDPI ≥ 85%, hepatitisC + , or AKI. CONCLUSIONS Recipients of high-risk KT with BMI ≥ 35 kg/m2 have higher risk of DCGL and recipients age ≥ 70 years have higher risk of death in low CV, compared to high CV. Future studies should identify care practices associated with CV that support optimal outcomes after KT.

Abstract
Well-selected patients with kidney disease and diabetes mellitus who undergo simultaneous kidney-pancreas transplantation often experience dramatic improvements in quality of life and long-term survival compared to those who remain on medical therapy. Over the past several years the importance of frailty in the pancreas transplant candidate and recipient populations has grown. More patients with advanced age have entered the waitlist, and complications from prolonged diabetes, even in younger patients, have created increased evidence of risk for frailty. Given these concerns, and the broad challenges facing pancreas transplantation volumes overall, we generated this review to help establish the impact and implications. We summarize the interplay of immunological factors, aging, environmental factors, diabetes mellitus, and chronic kidney disease that put these patients at risk for frailty. We discuss its measurement and recommend a combination of two instruments (both well-validated and one entirely objective). We describe the outcomes for patients before and after pancreas transplantation who may have frailty, and what interventions can be taken to mitigate its effects. Broader investigation into frailty in the pancreas transplant population is needed to better understand how to select patients for pancreas transplantation and to how manage its consequences thereafter.

Abstract
BACKGROUND Ischemia-reperfusion (IR) of a kidney transplant (KTx) upregulates TNF α production that amplifies allograft inflammation and may negatively affect transplant outcomes. METHODS We tested the effects of blocking TNF peri-KTx via a randomized, double-blind, placebo-controlled, 15-center, phase 2 clinical trial. A total of 225 primary transplant recipients of deceased-donor kidneys (KTx; 38.2% Black/African American, 44% White) were randomized to receive intravenous infliximab (IFX) 3 mg/kg or saline placebo (PLBO) initiated before kidney reperfusion. All patients received rabbit anti-thymocyte globulin induction and maintenance immunosuppression (IS) with tacrolimus, mycophenolate mofetil, and prednisone. The primary end point was the difference between groups in mean 24-month eGFR. RESULTS There was no difference in the primary end point of 24-month eGFR between IFX (52.45 ml/min per 1.73 m 2 ; 95% CI, 48.38 to 56.52) versus PLBO (57.35 ml/min per 1.73 m 2 ; 95% CI, 53.18 to 61.52; P =0.1). There were no significant differences between groups in rates of delayed graft function, biopsy-proven acute rejection (BPAR), development of de novo donor-specific antibodies, or graft loss/death. Immunosuppression did not differ, and day 7 post-KTx plasma analyses showed approximately ten-fold lower TNF ( P <0.001) in IFX versus PLBO. BK viremia requiring IS change occurred more frequently in IFX (28.9%) versus PLBO (13.4%; P =0.004), with a strong trend toward higher rates of BKV nephropathy in IFX (13.3%) versus PLBO (4.9%; P =0.06). CONCLUSIONS IFX induction therapy does not benefit recipients of kidney transplants from deceased donors on this IS regimen. Because the intervention unexpectedly increased rates of BK virus infections, our findings underscore the complexities of targeting peritransplant inflammation as a strategy to improve KTx outcomes.Clinical Trial registry name and registration number:clinicaltrials.gov (NCT02495077).

Abstract
Simultaneous pancreas-kidney transplantation (SPK) carries about a 7%–22% risk of technical failure, but the impact of early pancreas allograft loss on subsequent kidney graft and patient survival is not well-defined. We examined national transplant registry data for type 1 diabetic patients who received SPK between 2000 and 2021. Associations of transplant type (i.e., SPK, deceased‐donor kidney transplant [DDKA], living‐donor kidney transplant [LDKA]) with kidney graft failure and patient survival were estimated by multivariable inverse probability of treatment-weighted accelerated failure-time models. Compared to SPK recipients with a functioning pancreas graft 3 months posttransplant (SPK,P+), LDKA had 18% (Time Ratio [TR] 0.82, 95%CI: 0.70–0.95) less graft survival time and 18% (TR 0.82, 95%CI: 0.68–0.97) less patient survival time, DDKA had 23% (TR 0.77, 95%CI: 0.68–0.87) less graft survival time and 29% (TR 0.71, 95%CI: 0.62–0.81) less patient survival time, and SPK with early pancreas graft loss had 34% (TR 0.66, 95%CI: 0.56–0.78) less graft survival time and 34% (TR 0.66, 95%CI: 0.55–0.79) less patient survival time. In conclusion, SPK,P+ recipients have better kidney allograft and patient survival compared with LDKA and DDKA. Early pancreas graft failure results in inferior kidney and patient survival time compared to kidney transplant alone.

Abstract
Background The coronavirus disease 2019 (COVID-19) pandemic created unprecedented challenges for solid organ transplant centers worldwide. We sought to assess an international perspective on COVID-19 vaccine mandates and rationales for or against mandate policies. Methods We administered an electronic survey to staff at transplant centers outside the United States (October 14, 2021-January 28, 2022) assessing the reasons cited by transplant centers for or against implementing a COVID-19 vaccine mandate. Each responding center was represented once in the analysis. Results Respondents (N=90) represented 27 countries on five continents. Half (51%) of responding transplant center representatives reported implementing a COVID-19 vaccine mandate, 38% did not, and 12% were unsure. Staff at centers implementing a vaccine mandate cited efficacy of pretransplant vaccination versus post-transplant vaccination, importance for public health, and minimizing exposure of other patients as rationale for the mandate. Of centers with a mandate, the majority (81%) of the centers mandate vaccination regardless of prior SARS-CoV-2 infection status and regardless of prevaccination spike-protein antibody titer or other markers of prior infection. Only 27% of centers with a vaccine mandate for transplant candidates also extended a vaccine requirement to living donor candidates. Centers not implementing a vaccine mandate cited concerns for undue pressure on transplant candidates, insufficient evidence to support vaccine mandates, equity, and legal considerations. Conclusions The approach to pretransplant COVID-19 vaccination mandate policies at international transplant centers is heterogeneous. International transplant centers with a vaccine mandate were more willing to extend vaccine requirements to candidates' support persons, cohabitants, and living donors. Broader stakeholder engagement to overcome vaccine hesitancy across the world is needed to increase the acceptance of pretransplant COVID-19 vaccination to protect the health of transplant patients.

Abstract
An electronic survey canvassing current policies of transplant centers regarding a COVID-19 vaccine mandate for transplant candidates and living donors was distributed to clinicians at US solid organ transplant centers performing transplants from October 14, 2021-November 15, 2021. Responses were received from staff at 141 unique transplant centers. These respondents represented 56.4% of US transplant centers, and responding centers performed 78.5% of kidney transplants and 82.4% of liver transplants in the year prior to survey administration. Only 35.7% of centers reported implementing a vaccine mandate, while 60.7% reported that vaccination was not required. A minority (42%) of responding centers with a vaccine mandate for transplant candidates also mandated vaccination for living organ donors. Centers with a vaccine mandate most frequently cited clinical evidence supporting the efficacy of pre-transplant vaccination (82%) and stewardship obligations to ensure organs were transplanted into the lowest risk patients (64%). Centers without a vaccine mandate cited a variety of reasons including administrative, equity, and legal considerations for their decision. Transplant centers in the United States exhibit significant heterogeneity in COVID-19 vaccination mandate policies for transplant candidates. While all centers encourage vaccination, most centers have not mandated COVID-19 vaccination for candidates and living donors, citing administrative opposition, legal prohibitions, and concern about equity in access to transplants.

Abstract
The use of routine monitoring of donor-derived cell-free DNA (dd-cfDNA) after kidney transplant may allow clinicians to identify subclinical allograft injury and intervene prior to development of clinically evident graft injury. To evaluate this, data from 1092 kidney transplant recipients monitored for dd-cfDNA over a three year period was analyzed to assess the association of dd-cfDNA with histologic evidence of allograft rejection. Elevation of dd-cfDNA (0.5% or more) was significantly correlated with clinical and subclinical allograft rejection. dd-cfDNA values of 0.5% or more were associated with a nearly three-fold increase in risk development of de novo donor specific antibodies (hazard ratio 2.71) and were determined to be elevated a median of 91 days (inter quartile range of 30-125 days) ahead of donor specific antibody identification. Persistently elevated dd-cfDNA (more than one result above the 0.5% threshold) predicted over a 25% decline in the estimated glomerular filtration rate over three years (hazard ratio 1.97). Therefore, routine monitoring of dd-cfDNA allowed early identification of clinically important graft injury. Biomarker monitoring complemented histology and traditional laboratory surveillance strategies as a prognostic marker and risk-stratification tool post-transplant. Thus, persistently low dd-cfDNA levels may accurately identify allograft quiescence, or absence of injury, paving the way for personalization of immunosuppression trials.

Abstract
Background The coronavirus disease 2019 (COVID‐19) pandemic has created unprecedented challenges for solid organ transplant programs worldwide. The aim of this study is to assess an international perspective on challenges faced by kidney transplant programs. Methods We administered an electronic survey instrument from January 3, 2021 to June 8, 2021 to staff at transplant programs outside the United States that comprised of 10 questions addressing the management of kidney transplant candidates with asymptomatic COVID‐19 infection or unvaccinated who receive an organ offer. Results Respondents (n = 62) represented 19 countries in five continents. Overall, 90.3% of respondents encourage vaccination on the waiting list and prior to planned living donor transplant. Twelve percent of respondents reported that they have decided to inactivate unsensitized candidates (calculated panel reactive antibody, cPRA <80%) until they received the two doses of vaccination, and 7% report inactivating candidates who have received their first vaccine dose pending receipt of their second dose. The majority (88.5%) of international respondents declined organs for asymptomatic, nucleic acid testing (NAT)+ patients during admission without documented prior infection. However, 22.9% of international respondents proceeded with kidney transplant in NAT+ patients who were at least 30 days from initial diagnosis with negative chest imaging. Conclusions Practitioners in some countries are less willing to accept deceased donor organs for waitlist candidates with incomplete COVID‐19 vaccination status and to wait longer before scheduling living donor transplant, compared to United States practices. Access to vaccinations and other resources may contribute to these differences. More research is needed to guide the optimal approach to vaccination before and after transplant.

Abstract
IMPORTANCE Increased levels of ambient fine particulate matter (PM2.5) air pollution are associated with increased risks for detrimental health outcomes, but risks for patients with kidney transplants (KTs) remain unknown. OBJECTIVE To investigate the association of PM2.5 exposure with KT outcomes. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study was conducted using data on patients who received KTs from 2004 to 2016 who were identified in the national US transplant registry and followed up through March 2021. Multiple databases were linked to obtain data on PM2.5 concentration, KT outcomes, and patient clinical, transplant, and contextual factors. Data were analyzed from April 2020 through July 2021. EXPOSURES Exposures included post-KT time-dependent annual mean PM2.5 level (in 10 μg/m3) and mean PM2.5 level in the year before KT (ie, baseline levels) in quartiles, as well as baseline annual mean PM2.5 level (in 10 μg/m3). MAIN OUTCOMES AND MEASURES Acute kidney rejection (ie, rejection within 1 year after KT), time to death-censored graft failure, and time to all-cause death. Multivariable logistic regression for kidney rejection and Cox analyses with nonlinear assessment of exposure-response for death-censored graft failure and all-cause death were performed. The national burden of graft failure associated with PM2.5 levels greater than the Environmental Protection Agency recommended level of 12 μg/m3 was estimated. RESULTS Among 112 098 patients with KTs, 70 522 individuals (62.9%) were older than age 50 years at the time of KT, 68 117 (60.8%) were men, and the median (IQR) follow-up was 6.0 (3.9-8.9) years. There were 37 265 Black patients (33.2%), 17 047 Hispanic patients (15.2%), 48 581 White patients [43.3%]), and 9205 patients (8.2%) of other race or ethnicity. The median (IQR) baseline PM2.5 level was 9.8 (8.3-11.9) μg/m3. Increased baseline PM2.5 level, compared with quartile 1 baseline PM2.5 level, was not associated with higher odds of acute kidney rejection for quartile 2 (adjusted odds ratio [aOR], 0.99; 95% CI, 0.92-1.06) but was associated with increased odds for quartile 3 (aOR, 1.11; 95% CI, 1.04-1.20) and quartile 4 (aOR, 1.13; 95% CI, 1.05-1.23). Nonlinear assessment of exposure-response for graft failure and death showed no evidence for nonlinearity. Increased PM2.5 levels were associated with increased risk of death-censored graft failure (adjusted hazard ratio [aHR] per 10 μg/m3 increase, 1.17; 95% CI, 1.09-1.25) and all-cause death (aHR per 10 μg/m3 increase, 1.21; 95% CI, 1.14-1.28). The national burden of death-censored graft failure associated with PM2.5 above 12 μg/m3 was 57 failures (95% uncertainty interval, 48-67 failures) per year among patients with KTs. CONCLUSIONS AND RELEVANCE This cohort study found that PM2.5 level was an independent risk factor associated with acute rejection, graft failure, and death among patients with KTs. These findings suggest that efforts toward decreasing levels of PM2.5 concentration may be associated with improved outcomes after KT.

Abstract
Kidney allograft failure and return to dialysis carry a high risk of morbidity. A practice survey was developed by the AST Kidney Pancreas Community of Practice workgroup and distributed electronically to the AST members. There were 104 respondents who represented 92 kidney transplant centers. Most survey respondents were transplant nephrologists at academic centers. The most common approach to immunosuppression management was to withdraw the antimetabolite first (73%), while only 12% responded they would withdraw calcineurin inhibitor (CNI) first. More than 60% reported that the availability of a living donor is the most important factor in their decision to taper immunosuppression, followed by risk of infection, risk of sensitization, frailty, and side effects of medications. More than half of respondents reported that embolization was either not available or offered to less than 10% as an option for surgical intervention. Majority reported that ≤50% of failed allograft patients were re-listed before dialysis, and less than a quarter of transplant nephrologists performed frequent visits with their patients with failed kidney allograft after they return to dialysis. This survey demonstrates heterogeneity in the care of patients with a failing allograft and the need for more evidence to guide improvements in clinical practice related to transition of care.

Abstract
The return to dialysis after allograft failure is associated with increased morbidity and mortality. This transition is made more complex by the rising numbers of patients who seek repeat transplantation and therefore may have indications for remaining on low levels of immunosuppression, despite the potential increased morbidity. Management strategies vary across providers, driven by limited data on how to transition off immunosuppression as the allograft fails and a paucity of randomized controlled trials to support one approach over another. In this review, we summarize the current data available for management and care of the failing allograft. Additionally, we discuss a suggested plan for immunosuppression weaning based upon the availability of re-transplantation and residual allograft function. We propose a shared-care model in which there is improved coordination between transplant providers and general nephrologists so that immunosuppression management and preparation for renal replacement therapy and/or repeat transplantation can be conducted with the goal of improved outcomes and decreased morbidity in this vulnerable patient group.

Abstract
Bw4 and Bw6 are strongly immunogenic epitopes routinely assigned based on HLA-B typing results per Organ Procurement and Transplantation Network (OPTN) policies. These public epitopes and their variants are shared by some cross-reactive HLA-A and -C antigens. Although epitope mismatch has been associated with poor transplant outcomes, previous studies did not find such associations for Bw4/6 mismatch as defined by HLA-B antigens only. We hypothesized that a broader definition for Bw4/Bw6 mismatch that includes cross-reactive HLA-A and -C antigens may reveal the risk associated with these epitopes. In this retrospective cohort study, we examined kidney transplantations between 2000 and 2016 in the OPTN database and determined the association of Bw4/6 mismatch across all class I HLA antigens and renal graft outcomes. Even by this broader definition, Bw4/6 mismatch was not independently associated with 1-year graft rejection (adjusted OR: 0.99, 95%CI 0.93-1.06) or death-censored graft survival (adjusted HR: 1.02, 95%CI 1.00-1.05). There was no significant association among recipients who were already sensitized at transplant either. Our findings suggest that Bw4/6 mismatch alone is not associated with poor renal graft outcomes despite their strong immunogenicity, and the load of epitope mismatches over a certain threshold is likely required to cause adverse clinical consequences.

Abstract
The coronavirus disease 2019 (COVID‐19) pandemic has created unprecedented challenges for solid organ transplant programs. While transplant activity has largely recovered, appropriate management of deceased donor candidates who are asymptomatic but have positive nucleic acid testing (NAT) for SARS‐CoV‐2 is unclear, as this result may reflect active infection or prolonged viral shedding. Furthermore, candidates who are unvaccinated or partially vaccinated continue to receive donor offers. In the absence of robust outcomes data, transplant professionals at US adult kidney transplant centers were surveyed (February 13, 2021 to April 29, 2021) to determine community practice (N: 92 centers, capturing 41% of centers and 57% of transplants performed). The majority (97%) of responding centers declined organs for asymptomatic NAT+ patients without documented prior infection. However, 32% of centers proceed with kidney transplant in NAT+ patients who were at least 30 days from initial diagnosis with negative chest imaging. Less than 7% of programs reported inactivating patients who were unvaccinated or partially vaccinated. In conclusion, despite national recommendations to wait for negative testing, many centers are proceeding with kidney transplant in patients with positive SARS‐CoV‐2 NAT results due to presumed viral shedding. Furthermore, few centers are requiring COVID‐19 vaccination prior to transplantation at this time.

Abstract
BACKGROUND Due to a substantial decline in pancreas transplantation (PT) across the United States over the past 15 years, we sought to understand the perceptions and practices of US PT programs. METHODS Surveys were sent to members of the American Society of Transplantation Surgeons and the American Society of Transplantation by email and professional society postings between August 2019 and November 2019. RESULTS One hundred twenty three responses were recorded from 56 unique programs. Program characteristics were obtained from the Scientific Registry of Transplant Recipients. Respondents were transplant surgeons (71%), transplant nephrologists (17%), trainees (9%), and allied professionals (3%). Programs were defined according to annual volume as: low (<5 PT/year), intermediate (6-20), or high (>20). High-volume programs reported that these factors were most important for increased PT: expansion of recipient selection, more aggressive donor utilization, and hiring of PT program-specific personnel. At both the program and national level, the vast majority (82% and 79%, respectively) felt the number of PTs currently performed are not in balance with patients' needs. CONCLUSIONS Overall, programs reported that the option of PT is not offered adequately to diabetic patients and that strategies to maintain higher PT volume are most evident at intermediate, and especially, high-volume programs.

Abstract
BACKGROUND Donor-derived cell-free DNA (dd-cfDNA) is a marker of allograft injury in transplant recipients; however, the relationship between dd-cfDNA and other clinical parameters associated with adverse allograft outcomes is not well-characterized. METHODS We performed a retrospective analysis of kidney transplant recipients from the DART cohort (ClinicalTrials.gov Identifier: NCT02424227) to evaluate the associations between eGFR decline, de novo donor-specific antibodies (dnDSA), and dd-cfDNA. RESULTS Both elevated dd-cfDNA (≥1%) and dd-cfDNA variability (≥.34%) in the first post-transplant year were associated with decline in eGFR ≥25% in the second year (21.4% vs. 4.1%, P = .005; 25% vs. 3.6%, P = .002, respectively). Compared to samples from DSA negative patients, samples from patients with concurrent de novo HLA DSAs had higher dd-cfDNA levels (P < .0001). DISCUSSION Abnormalities in dd-cfDNA levels are associated with clinical parameters commonly used as surrogate endpoints for adverse allograft outcomes, raising the possibility that molecular injury as characterized by dd-cfDNA could help identify patients at risk of these outcomes.

Abstract
The coronavirus disease 2019 (COVID‐19) pandemic poses unprecedented challenges to the transplant community, including organ procurement organizations (OPOs), transplant centers, regulatory agencies, and recipient candidates. Access to timely, accurate information on the status of deceased donor viral infection is essential in determining organ acceptance. The Organ Procurement and Transplantation Network expeditiously added fields to collect these data; however, use of the data collection fields was not uniform nationally. Standardized, field‐defined data capture and reporting are vital to ensure optimal organ utilization during this pandemic, and to prepare the community for subsequent challenges.

Abstract
BACKGROUND AND OBJECTIVES Kidneys from hepatitis C virus (HCV) viremic donors have become more commonly accepted for transplant, especially after effective direct-acting antiviral therapy became available in 2014. We examined the contemporary trend of kidney discard from donors with HCV seropositivity and viremia. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Data from the Organ Procurement and Transplantation Network were used to identify deceased donor kidneys recovered for transplant. The exposure was donor HCV antibody status in the first analyses, and donor HCV antibody and viremia status in the second analyses. Multilevel, multivariable logistic regression was used to assess the association of these HCV exposure measures with kidney discard, adjusted for donor characteristics. Multilevel analyses were conducted to account for similar kidney discard pattern within clusters of organ procurement organizations and regions. RESULTS Among 225,479 kidneys recovered from 2005 to 2019, 5% were from HCV seropositive donors. Compared with HCV seronegative kidneys, the odds of HCV seropositive kidney discard gradually declined, from a multivariable-adjusted odds ratio (aOR) of 7.06 (95% confidence interval [95% CI], 5.65 to 8.81) in 2014, to 1.20 (95% CI, 1.02 to 1.42) in 2019. Among 82,090 kidneys with nucleic acid amplification test results in 2015-2019, 4% were from HCV viremic donors and 2% were from aviremic seropositive donors. Compared with HCV aviremic seronegative kidneys, the odds of HCV viremic kidney discard decreased from an aOR of 4.89 (95% CI, 4.03 to 5.92) in 2018, to 1.48 (95% CI, 1.22 to 1.81) in 2019. By 2018 and 2019, aviremic seropositive status was not associated with higher odds of discard (2018: aOR, 1.13; 95% CI, 0.88 to 1.45; and 2019: aOR, 0.97; 95% CI, 0.76 to 1.23). CONCLUSIONS Despite the decrease in kidney discard in recent years, kidneys from viremic (compared with aviremic seronegative) donors still had 48% higher odds of discard in 2019. The potential of these discarded organs to provide successful transplantation should be explored.

Abstract
Chimeric antigen receptor T cells (CAR-T) are genetically modified T cells with a chimeric antigen receptor directed against a specific tumor-associated antigen like CD19 in lymphoma. CAR-T cells have shown encouraging activity against recurrent and refractory diffuse large B cell lymphomas (DLBCL). However concurrent use of immunosuppressive agents was prohibited in most CAR-T trials effectively excluding patients with prior solid organ transplantation (SOT) and posttransplant lymphoproliferative disorders (PTLD). We report the outcomes for three patients with PTLD refractory to immunochemotherapy 10-20 years after SOT who received CAR-T therapy between January 2018 and December 2019. One patient had an orthotopic heart transplant, the second had a deceased donor kidney transplant, and the third had a pancreas after kidney transplant (PAK). All patients developed complications of CAR-T therapy such as cytokine release syndrome, immune effector cell-associated neurotoxicity syndrome, and acute kidney injury requiring renal replacement therapy in the two out of three patients. All patients expired after withdrawal of care due to lack of response to CAR-T therapy. In addition, the PAK patient developed acute pancreatitis after CAR-T therapy. This case series identifies the challenges of using CAR-T therapy to manage refractory PTLD in SOT recipients and its possible complications.

Abstract
Immune checkpoint inhibitors (ICIs) are widely used for various malignancies. However, their safety and efficacy in patients with a kidney transplant have not been defined. To delineate this, we conducted a multicenter retrospective study of 69 patients with a kidney transplant receiving ICIs between January 2010 and May 2020. For safety, we assessed the incidence, timing, and risk factors of acute graft rejection. For efficacy, objective response rate and overall survival were assessed in cutaneous squamous cell carcinoma and melanoma, the most common cancers in our cohort, and compared with stage-matched 23 patients with squamous cell carcinoma and 14 with melanoma with a kidney transplant not receiving ICIs. Following ICI treatment, 29 out of 69 (42%) patients developed acute rejection, 19 of whom lost their allograft, compared with an acute rejection rate of 5.4% in the non-ICI cohort. Median time from ICI initiation to rejection was 24 days. Factors associated with a lower risk of rejection were mTOR inhibitor use (odds ratio 0.26; 95% confidence interval, 0.09-0.72) and triple-agent immunosuppression (0.67, 0.48-0.92). The objective response ratio was 36.4% and 40% in the squamous cell carcinoma and melanoma subgroups, respectively. In the squamous cell carcinoma subgroup, overall survival was significantly longer in patients treated with ICIs (median overall survival 19.8 months vs. 10.6 months), whereas in the melanoma subgroup, overall survival did not differ between groups. Thus, ICIs were associated with a high risk of rejection in patients with kidney transplants but may lead to improved cancer outcomes. Prospective studies are needed to determine optimal immunosuppression strategies to improve patient outcomes.

Abstract
The construct of frailty was first developed in gerontology to help identify older adults with increased vulnerability when confronted with a health stressor. This article is a review of studies in which frailty has been applied to pre- and post-kidney transplantation (KT) populations. Although KT is the optimal treatment for end-stage kidney disease (ESKD), KT candidates often must overcome numerous health challenges associated with ESKD before receiving KT. After KT, the impacts of surgery and immunosuppression represent additional health stressors that disproportionately impact individuals with frailty. Frailty metrics could improve the ability to identify KT candidates and recipients at risk for adverse health outcomes and those who could potentially benefit from interventions to improve their frail status. The Physical Frailty Phenotype (PFP) is the most commonly used frailty metric in ESKD research, and KT recipients who are frail at KT (~20% of recipients) are twice as likely to die as nonfrail recipients. In addition to the PFP, many other metrics are currently used to assess pre- and post-KT vulnerability in research and clinical practice, underscoring the need for a disease-specific frailty metric that can be used to monitor KT candidates and recipients. Although frailty is an independent risk factor for post-transplant adverse outcomes, it is not factored into the current transplant program risk-adjustment equations. Future studies are needed to explore pre- and post-KT interventions to improve or prevent frailty.

Abstract
Background Transplant practices related to use of organs from Hepatitis C virus infected donors (DHCV+) is evolving rapidly. Methods We surveyed U.S. kidney transplant programs by email and professional society listserv postings between 7/19-1/20 to assess attitudes, management strategies, and barriers related to use of viremic (nucleic acid testing (NAT)+) donor organs in HCV uninfected recipients. Results Staff at 112 unique programs responded, representing 54% of U.S. adult kidney transplant programs and 69% of adult deceased donor kidney transplant volume in 2019. Most survey respondents were transplant nephrologists (46%) or surgeons (43%). Among responding programs, 67% currently transplant DHCV antibody+/NAT- organs under a clinical protocol or as standard of care. By comparison, only 58% offer DHCV NAT+ kidney transplant to HCV- recipients, including 35% under clinical protocols, 14% as standard of care, and 9% under research protocols. Following transplant of DHCV NAT+ organs to uninfected recipients, 53% start direct acting antiviral agent (DAA) therapy after discharge and documented viremia. Viral monitoring protocols after DHCV NAT+ to HCV uninfected recipient kidney transplantation varied substantially. 56% of programs performing these transplants report having an institutional plan to provide DAA treatment if declined by the recipient's insurance. Respondents felt a mean decrease in waiting time of ≥18 months (range 0-60) justifies the practice. Program concerns related to use of DHCV NAT+ kidneys include insurance coverage concerns (72%), cost (60%), and perceived risk of transmitting resistant infection (44%). Conclusions Addressing knowledge about safety and logistical/financial barriers related to use of DHCV NAT+ kidney transplantation for HCV uninfected recipients may help reduced discards and expand the organ supply.

Abstract
Hydroxychloroquine (HCQ) is an antimalarial drug with immunomodulatory effects used to treat systemic lupus erythematosus (SLE) and scleroderma. The antiviral effects of HCQ have raised attention in the context of the COVID-19 pandemic, although safety is controversial. We examined linkages of national transplant registry data with pharmaceutical claims and Medicare billing claims to study HCQ use among Medicare-insured kidney transplant recipients with SLE or scleroderma (2008-2017; N = 1820). We compared three groups based on immunosuppression regimen 7 months-to-1 year post transplant: (a) tacrolimus (Tac) + mycophenolic acid (MPA) + prednisone (Pred) (referent group, 77.7%); (b) Tac + MPA + Pred + HCQ (16.5%); or (c) other immunosuppression + HCQ (5.7%). Compared to the referent group, recipients treated with other immunosuppression + HCQ had a 2-fold increased risk of abnormal ECG or QT prolongation (18.9% vs. 10.7%; aHR,1.12 1.963.42 , p = .02) and ventricular arrhythmias (15.2% vs. 11.4%; aHR,1.00 1.813.29 , p = .05) in the >1-to-3 years post-transplant. Tac + MPA + Pred + HCQ was associated with increased risk of ventricular arrhythmias (13.5% vs. 11.4%; aHR,1.02 1.542.31 , p = .04) and pancytopenia (35.9% vs. 31.4%; aHR,1.03 1.311.68 , p = .03) compared to triple immunosuppression without HCQ. However, HCQ-containing regimens were not associated with an increased risk of death or graft failure. HCQ may be used safely in selected kidney transplant recipients in addition to their maintenance immunosuppression, although attention to arrhythmias is warranted.

Abstract
The clinical importance of subclinical, early T cell-mediated rejection (Banff TCMR 1A and borderline lesions) remains unclear, due, in part to the fact that histologic lesions used to characterize early TCMR can be nonspecific. Donor-derived cell-free DNA (dd-cfDNA) is an important molecular marker of active graft injury. Over a study period from June 2017 to May 2019, we assessed clinical outcomes in 79 patients diagnosed with TCMR 1A/borderline rejection across 11 US centers with a simultaneous measurement of dd-cfDNA. Forty-two patients had elevated dd-cfDNA (≥0.5%) and 37 patients had low levels (<0.5%). Elevated levels of dd-cfDNA predicted adverse clinical outcomes: among patients with elevated cfDNA, estimated glomerular filtration rate declined by 8.5% (interquartile rate [IQR] -16.22% to -1.39%) (-3.50 mL/min/1.73 m2 IQR -8.00 to -1.00) vs 0% (-4.92%, 4.76%) in low dd-cfDNA patients (P = .004), de novo donor-specific antibody formation was seen in 40% (17/42) vs 2.7% (P < .0001), and future or persistent rejection occurred in 9 of 42 patients (21.4%) vs 0% (P = .003). The use of dd-cfDNA may complement the Banff classification and to risk stratify patients with borderline/TCMR 1A identified on biopsy.

Abstract
Abstract
Background and Aims
With more transplant centers in the United States are accepting hepatitis C virus infected (HCV+) deceased donor kidneys (dHCV+), the trend of non-utilization and decline of these organs have not been re-examined.
Method
We used data from the national Organ Procurement and Transplantation Network on deceased donor kidneys between Jan 2000 and Dec 2018 in the United States. Kidney non-utilization for HCV+ was defined as a positive donor HCV status and positive hepatitis as the reason for non-utilization. dHCV+ kidney decline was defined as a donor HCV+ status among kidneys recovered for transplantation but not transplanted. We assessed associations of a dHCV+ status with kidney non-utilization or decline, adjusted for donor characteristics (age, race, sex, body mass index, diabetes, hypertension, kidney donor profile index), using multivariable logistic regression.
Results
A total of 274,570 deceased donor kidneys procured for transplantation between 2000 and 2018 were identified. Among these kidneys, 4.1% were from dHCV+. Proportion of dHCV+ non-utilization among all non-utilized kidneys increased from 2000-2005 (3.9%) and then subsequently declined. This proportion increased slightly to 1.1% in 2014 and decreased to 0.5, 0.8, 0.4, 0.6% in 2015-2018, respectively. Multivariable-adjusted odds ratios for dHCV+ non-utilization and decline by year demonstrate consistently an increasing trend from 2000-2006 followed by a decreasing trend from 2006-2011 (Fig A-B). Multivariable-adjusted odds ratios for dHCV+ (compared to dHCV-) non-utilization and decline increased to 6.56 (95% CI 5.30-8.12) and 6.66 (95% CI 5.39-8.24), respectively, in 2012, and decreased to 2.32 (95% CI 2.01-2.69) and 2.28 (95% CI 1.98-2.64), respectively, in 2018.
Conclusion
dHCV+ non-utilization and decline have decreased in the last few years, particularly after 2014. 2018 had a historic lowest odds ratio for non-utilization and decline of dHCV+ organs, which reflects the increased acceptability of transplant centers to these kidneys. Overall, since 2014, the odds ratios for dHCV+ non-utilization and decline decreased by half. Yet, there is more room for decreasing the non-utilization and decline for these potentially life-saving organs.

Abstract
Understanding the economic implications of induction and maintenance immunosuppression (ISx) is important in developing personalized kidney transplant (KTx) care. Using data from a novel integrated data set including financial records from the University Health System Consortium, Medicare, and pharmacy claims (2007-2014), we estimated the differences in the impact of induction and maintenance ISx regimens on transplant hospitalization costs and Medicare payments from KTx to 3 years. Use of thymoglobulin (TMG) significantly increased transplant hospitalization costs ($12 006; P = .02), compared with alemtuzumab and basiliximab. TMG resulted in lower Medicare payments in posttransplant years 1 (-$2058; P = .05) and 2 (-$1784; P = .048). Patients on steroid-sparing ISx incurred relatively lower total Medicare spending (-$10 880; P = .01) compared with patients on triple therapy (tacrolimus, antimetabolite, and steroids). MPA/AZA-sparing, mammalian target of rapamycin inhibitors-based, and cyclosporine-based maintenance ISx regimens were associated with significantly higher payments. Alternative ISx regimens were associated with different KTx hospitalization costs and longer-term payments. Future studies of clinical efficacy should also consider cost impacts to define the economic effectiveness of alternative ISx regimens.

Abstract
Successful simultaneous pancreas-kidney transplantation (SPK) improves quality-of-life and prolongs kidney allograft and patient survival in type-1 diabetic (T1DM) patients. However, the use of SPK in type-2 diabetic (T2DM) patients remains limited. We examined a national transplant registry for 35 849 T2DM kidney disease patients who received transplant between 2000 and 2016 and survived the first 3 months with a functioning kidney, and categorized as: deceased-donor kidney transplant alone (DD-KA, 68%), living-donor kidney transplant alone (LD-KA, 30%), or SPK (2%). Among SPK recipients, 6% had pancreas allograft failure within 3 months (SPK,P-) and 94% had a functional pancreas (SPK,P+). Associations of transplant type with kidney allograft failure and death (multivariable-adjusted hazard ratio, 95%LCL aHR95%UCL ), over follow-up through December 2018, were quantified by multivariable inverse probability of treatment weighted survival analyses. SPK recipients had better kidney graft and patient survival than LD-KA or DD-KA recipients. Compared to SPK,P+, DD-KA, or LD-KA recipients had significantly higher risk of kidney allograft failure (DD-KA: aHR 1.53 2.203.17 ; LD-KA: aHR 1.29 1.872.71 ) and death (DD-KA: aHR 2.12 3.255.00 ; LD-KA: aHR 1.54 2.353.59 ). SPK,P- recipients had significantly higher risk of death (aHR 1.68 3.306.50 ). Similar to T1DM, T2DM patients with SPK have a survival benefit compared to those with kidney transplant alone, but this benefit depends upon successful early pancreas function.

Abstract
BACKGROUND Given the potential utility of frailty, a clinical phenotype of decreased physiologic reserve and resistance to stressors, to predict postkidney transplant (KT) outcomes, we sought to understand the perceptions and practices regarding frailty measurement in US KT programs. METHODS Surveys were emailed to American Society of Transplantation Kidney/Pancreas Community of Practice members and 202 US transplant programs (November 2017 to April 2018). Program characteristics were gleaned from Scientific Registry of Transplant Recipients. RESULTS The 133 responding programs (response rate = 66%) represented 77% of adult KTs and 79% of adult KT candidates in the United States. Respondents considered frailty to be a useful concept in evaluating candidacy (99%) and endorsed a need to develop a frailty measurement specific to KT (92%). Frailty measurement was more common during candidacy evaluation (69%) than during KT admission (28%). Of the 202 programs, 38% performed frailty assessments in all candidates while 23% performed assessments only for older candidates. There was heterogeneity in the frailty assessment method; 18 different tools were utilized to measure frailty. The most common tool was a timed walk test (19%); 67% reported performing >1 tool. Among programs that measure frailty, 53% reported being less likely to list frail patients for KT. CONCLUSIONS Among US KT programs, frailty is recognized as a clinically relevant construct and is commonly measured at evaluation. However, there is considerable heterogeneity in the tools used to measure frailty. Efforts to identify optimal measurement of frailty using either an existing or a novel tool and subsequent standardization of its measurement and application across KT programs should be considered.
