Abstract
With increasing knowledge of immunologic factors and with the advent of potent immunosuppressive agents, the last several decades have seen significantly improved kidney allograft survival. However, despite overall improved short to medium-term allograft survival, long-term allograft outcomes remain unsatisfactory. A large body of literature implicates acute and chronic rejection as independent risk factors for graft loss. In this article, we review measures taken at various stages in the kidney transplant process to minimize the risk of rejection. In the pre-transplant phase, it is imperative to minimize the risk of sensitization, aim for better HLA matching including eplet matching and use desensitization in carefully selected high-risk patients. The peri-transplant phase involves strategies to minimize cold ischemia times, individualize induction immunosuppression and make all efforts for better HLA matching. In the post-transplant phase, the focus should move towards individualizing maintenance immunosuppression and using innovative strategies to increase compliance. Acute rejection episodes are risk factors for significant graft injury and development of chronic rejection thus one should strive for early detection and aggressive treatment. Monitoring for DSA development, especially in high-risk populations, should be made part of transplant follow-up protocols. A host of new biomarkers are now commercially available, and these should be used for early detection of rejection, immunosuppression modulation, prevention of unnecessary biopsies and monitoring response to rejection treatment. There is a strong push needed for the development of new drugs, especially for the management of chronic or resistant rejections, to prolong graft survival. Prevention of rejection is key for the longevity of kidney allografts. This requires a multipronged approach and significant effort on the part of the recipients and transplant centers.

The Mediating Role of Self-Perceived Burden Between Social Support and Fear of Progression in Renal Transplant Recipients: A Multicenter Cross-Sectional Study. Psychol Res Behav Manag 2023; 16:3623-3633. [PMID: 37693331 PMCID: PMC10488562 DOI: 10.2147/prbm.s424844] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Accepted: 08/17/2023] [Indexed: 09/12/2023] Open
Abstract
Purpose To explore the mechanism of social support and fear of progression (FoP) in renal transplant recipients (RTRs) and the self-perceived burden that acts as a mediator between social support and FoP. Patients and Methods Sociodemographic and clinical characteristics, the Social Support Rating Scale (SSRS), the Self-Perceived Burden Scale (SPBS), and the Fear of Progression-Questionnaire-Short Form (FoP-Q-SF) were used. Structural equation modeling (SEM) was used to examine the mediating role of self-perceived burden. Results Our results showed that social support was negatively related to the self-perceived burden (r = -0.28, p < 0.001) and FoP (r = -0.37, p < 0.001). Moreover, we determined that self-perceived burden was positively related to FoP (r = 0.58, p < 0.001) and that the indirect effect of social support on FoP via self-perceived burden was significant (β = -0.172, 95% CI: -0.253, -0.097), and with a mediating effect value of 36.9%. Conclusion The FoP in RTRs is a concern. Higher social support and lower self-perceived burden can reduce the risk of FoP. Healthcare professionals (HCPs) should assist RTRs in correctly evaluating an individual's social support system, helping them optimize social support to reduce the self-perceived burden and the development of FoP.

Outcomes After Deceased Donor Kidney Transplantation Using Kidney Allografts With Marginal Perfusion Parameters. Transplant Proc 2023; 55:1561-1567. [PMID: 37393170 DOI: 10.1016/j.transproceed.2023.05.026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2023] [Revised: 04/20/2023] [Accepted: 05/16/2023] [Indexed: 07/03/2023]
Abstract
BACKGROUND This study examines outcomes of deceased donor kidney transplantation (DDKT) in recipients of kidney allografts with marginal perfusion parameters. METHODS Allografts with marginal perfusion parameters (resistance index [RI] >0.4 and pump flow rate [F] <70 mL/min; MP group) were compared with those with good parameters (RI <0.4 and F >70 mL/min; GP group) for DDKT recipients between January 1996 and November 2017 after hypothermic pulsatile perfusion. Demographics, creatinine, cold ischemia times (CIT), delayed graft function (DGF), and recipient glomerular filtration rate at pre- and post-transplant were noted. The primary outcome was graft survival post-transplant. RESULTS In the MP (n = 31) versus GP (n = 1281) group, the median recipient was aged 57 years versus 51 years; the median donor was aged 47 versus 37 years; terminal creatinine was 0.9 versus 0.9 mg/dL; CIT was 10.2 versus 13 hours, and the RI and flow were 0.46 and 60 mL/min versus 0.21 and 120 mL/min. The DGF rate was 19% (MP) versus 8% (GP). The graft survival in the MP versus GP group was 81% versus 90% (1 year), 65% versus 79% (3 years), 65% versus 73% (4 years), and 45% versus 68% (5 years). CONCLUSION Carefully selected kidney allografts after comprehensive donor and recipient evaluation may allow for the use of these routinely discarded kidneys with marginal perfusion parameters.

Abstract
The epidemiology of human immunodeficiency virus (HIV) has shifted such that Black individuals disproportionately represent incident HIV diagnoses. While risk of end-stage kidney disease (ESKD) among people with HIV (PWH) has declined with effective antiretroviral therapies, a substantial racial disparity in ESKD burden exists with the greatest prevalence among Black PWH. Disparities in waitlisting for kidney transplantation, the optimal treatment for ESKD, exist for both PWH and Black individuals without HIV, but it is unknown whether these characteristics together exacerbate such disparities. Six hundred two thousand six ESKD patients were identified from the United States Renal Data System (January 1, 2007 to December 31, 2017), and HIV-status was determined through Medicare claims. Cox proportional hazards regression was used to determine waitlisting rates. Multiplicative interaction terms between HIV-status and race were examined. The 6250 PWH were significantly younger, more commonly Black, and less commonly female than those without HIV. HIV-status and race were independently associated with 50% and 12% lower likelihood of waitlisting, respectively [adjusted hazard ratio (aHR): 0.50, 95% confidence interval (CI): 0.36-0.69, p < 0.001; aHR: 0.88, 95% CI: 0.87-0.90, p < 0.001]. There was also a significant interaction present between HIV-status and Black race (aHR: 0.80, 95% CI: 0.66-0.98, p < 0.001) such that, while HIV-status and Black race were independently associated with decreased waitlisting, the interaction of Black race and HIV-status exacerbated those disparities. While limited by lack of HIV-specific data that may impact inferences with respect to race, additional studies are urgently needed to understand the interplay between HIV risk factors, HIV-stigma, and racism, and how intersectionality may exacerbate disparities in transplantation among PWH.

Abstract
Rationale & Objective Many older adults prefer quality of life over longevity, and some prefer conservative kidney management (CKM) over dialysis. There is a lack of patient-decision aids for adults aged 75 years or older facing kidney therapy decisions, which not only include information on dialysis and CKM but also encourage end-of-life planning. We iteratively developed a paper-based patient-decision aid for older people with low literacy and conducted surveys to assess its acceptability. Study Design Design-based research. Setting and Participants Informed by design-based research principles and theory of behavioral activation, a multidisciplinary team of experts created a first version of the patient-decision aid containing 2 components: (1) educational material about kidney therapy options such as CKM, and (2) a question prompt list relevant to kidney therapy and end-of-life decision making. On the basis of the acceptability input of patients and caregivers, separate qualitative interviews of 35 people receiving maintenance dialysis, and with the independent feedback of educated layperson, we further modified the patient-decision aid to create a second version. Analytical Approach We used descriptive statistics to present the results of acceptability surveys and thematic content analyses for patients' qualitative interviews. Results The mean age of patients (n=21) who tested the patient-decision aid was 80 years and the mean age of caregivers (n=9) was 70 years. All respondents held positive views about the educational component and would recommend the educational component to others (100% patients and caregivers). Most of the patients reported that the question prompt list helped them put concerns into words (80% patients and 88% caregivers) and would recommend the question prompt list to others (95% patients and 100% caregivers). Limitations Single-center study. Conclusions Both components of the patient-decision aid received high acceptability ratings. We plan to launch a larger effectiveness study to test the outcomes of a decision-supporting intervention combining the patient-decision aid with palliative care-based decision coaching.

Abstract
Among renal replacement therapies, preemptive kidney transplantation (PKT) presents the best clinical, social, and economic results. However, it is still infrequently chosen as first therapy for patients with irreversible kidney failure. Initiatives in different parts of the world were developed to identify the reasons why PKT is still not widely used and to facilitate the access of patients with end-stage kidney disease to the advantages associated with it. This article addresses the main advantages and difficulties of PKT and discusses when it should be indicated and how to prepare potential recipients for PKT.

Abstract
INTRODUCTION Accurate determination of glomerular filtration rate (GFR) is crucial for selection of kidney donors. Nuclear medicine methods are considered accurate in measuring GFR but are not always easily available. The four-variable Modification of Diet in Renal Disease (MDRD4), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), and Full Age Spectrum (FAS) formulas are common equations for estimating GFR and are recommended for initial assessment of kidney donors. The aim of this study was to evaluate the performance of these GFR estimation equations compared with technetium-99m diethylenetriaminepentaacetic acid ([99mTc]Tc-DTPA) clearance. METHODS We compared GFR estimation by [99mTc]Tc-DTPA clearance using a two-blood sample method with estimation by MDRD4, CKD-EPI, and FAS creatinine-based equations in a population of healthy potential kidney donors. RESULTS A total of 195 potential kidney donors (68.2% female; mean age 49 years, range 21-75 years) were included in this study. Mean [99mTc]Tc-DTPA measured GFR (mGFR) was 101.5 ± 19.1 mL/min/1.73 m2. All three equations underestimated the GFR value measured by [99mTc]Tc-DTPA (MDRD4: -11.5 ± 18.8 mL/min/1.73 m2; CKD-EPI: -5.0 ± 17.4 mL/min/1.73 m2; FAS: -8.3 ± 17.4 mL/min/1.73 m2). Accuracy within 30% and 10% of the measured GFR value was highest for CKD-EPI. CONCLUSION The CKD-EPI equation showed better performance in estimating GFR in healthy potential kidney donors, proving to be a more accurate tool in the initial assessment of kidney donors. However, creatinine-based equations tended to underestimate kidney function. Therefore, GFR should be confirmed by another method in potential kidney donors.

Abstract
Donor-recipient matching is a highly individualized and complex component of solid organ transplantation. Flowcytometry crossmatching (FC-XM) is an integral step in the matching process that is used to detect pre-formed deleterious anti-donor immunoglobulin. Despite high sensitivity in detecting cell-bound immunoglobulin, FC-XM is not able to determine the source or function of immunoglobulins detected. Monoclonal antibody therapeutic agents used in a clinic can interfere with the interpretation of FC-XM. We combined data from the prospectively maintained Antibody Society database and Human Protein Atlas with a comprehensive literature review of PubMed to summarize known FC-XM-interfering antibody therapeutics and identify potential interferers. We identified eight unique FC-XM-interfering antibody therapeutics. Rituximab (anti-CD20) was the most-cited agent. Daratumuab (anti-CD38) was the newest reported agent. We identified 43 unreported antibody therapeutics that may interfere with FC-XM. As antibody therapeutic agents become more common, identifying and mitigating FC-XM interference will likely become an increased focus for transplant centers.

Abstract
PURPOSE Although congenital anomalies of the kidney and urinary tract (CAKUT) are among the leading causes of end-stage kidney disease (ESKD) in children and young adults, kidney transplantation access for this population has not been well studied in the US. We compared transplantation access in the US based on whether the etiology of kidney disease was secondary to CAKUT, and additionally by CAKUT subgroups (anatomic vs. inherited causes of CAKUT). METHODS Using the United States Renal Data System, we conducted a retrospective cohort study of 80,531 children and young adults who started dialysis between 1995 and 2015. We used adjusted Cox models to examine the association between etiology of kidney disease (CAKUT vs. non-CAKUT, anatomic vs. inherited) and receipt of kidney transplantation, and secondarily, receipt of a living vs. deceased donor kidney transplant. RESULTS Overall, we found an increased likelihood of kidney transplantation access for participants with CAKUT compared to those without CAKUT (HR 1.23; 95% CI 1.20-1.27). Among the subset of individuals with CAKUT as the attributed cause of ESKD, we found a lower likelihood of kidney transplantation in those with anatomic causes of CAKUT compared to those with inherited causes of CAKUT (adjusted HR 0.85; 0.81-0.90). CONCLUSION There are notable disparities in kidney transplantation rates among CAKUT subgroups. Those with anatomic causes of CAKUT started on dialysis have significantly reduced access to kidney transplantations compared to individuals with inherited causes of CAKUT who were initiated on dialysis. Further studies are needed to understand barriers to transplantation access in this population.

Abstract
Importance Allocation of deceased donor kidneys is meant to follow a ranked match-run list of eligible candidates, but transplant centers with a 1-to-1 relationship with their local organ procurement organization have full discretion to decline offers for higher-priority candidates and accept them for lower-ranked candidates at their center. Objective To describe the practice and frequency of transplant centers placing deceased donor kidneys with candidates who are not the highest rank at their center according to the allocation algorithm. Design, Setting, and Participants This retrospective cohort study used 2015 to 2019 organ offer data from US transplant centers with a 1-to-1 relationship with their local organ procurement organization, following candidates for transplant events from January 2015 to December 2019. Participants were deceased kidney donors with a single match-run and at least 1 kidney transplanted locally and adult, first-time, kidney-only transplant candidates receiving at least 1 offer for a locally transplanted deceased donor kidney. Data were analyzed from March 1, 2022 to March 28, 2023. Exposure Demographic and clinical characteristics of donors and recipients. Main Outcomes and Measures The outcome of interest was kidney transplantation into the highest-priority candidate (defined as transplanted after zero declines for local candidates in the match-run) vs a lower-ranked candidate. Results This study assessed 26 579 organ offers from 3136 donors (median [IQR] age, 38 [25-51] years; 2903 [62%] men) to 4668 recipients. Transplant centers skipped their highest-ranked candidate to place kidneys further down the match-run for 3169 kidneys (68%). These kidneys went to a median (IQR) of the fourth- (third- to eighth-) ranked candidate. Higher kidney donor profile index (KDPI; higher score indicates lower quality) kidneys were less likely to go to the highest-ranked candidate, with 24% of kidneys with KDPI of at least 85% going to the top-ranked candidate vs 44% of KDPI 0% to 20% kidneys. When comparing estimated posttransplant survival (EPTS) scores between the skipped candidates and the ultimate recipients, kidneys were placed with recipients with both better and worse EPTS than the skipped candidates, across all KDPI risk groups. Conclusions and Relevance In this cohort study of local kidney allocation at isolated transplant centers, we found that centers frequently skipped their highest-priority candidates to place kidneys further down the allocation prioritization list, often citing organ quality concerns but placing kidneys with recipients with both better and worse EPTS with nearly equal frequency. This occurred with limited transparency and highlights the opportunity to improve the matching and offer algorithm to improve allocation efficiency.

Abstract
Conceptual frameworks are valuable resources that can be used to guide the planning, evaluation, and development of healthcare services. However, there are currently no comprehensive frameworks focused on organ donation and transplantation that identify the critical factors underlying a successful national program. To address this knowledge gap, we developed a conceptual framework that takes into account all major domains of influence, including political and societal aspects as well as clinical implementation. The framework was initially constructed based on a targeted review of the relevant medical literature. Feedback provided by a panel of international experts was incorporated into the framework via an iterative process. The final framework features 16 essential domains that are critical for initiating and maintaining a successful program and improving the health of patients with organ failure. Of particular note, these domains are subject to three overarching health system principles: responsiveness, efficiency, and equity. This framework represents a first attempt to develop a whole-system view of the various factors that contribute to the success of a national program. These findings provide a useful tool that can be adapted to any jurisdiction and used to plan, evaluate, and improve organ donation and transplantation programs.

Abstract
BACKGROUND In the United States, Hispanic/Latinx patients receive disproportionately fewer living donor kidney transplants (LDKTs) than non-Hispanic White patients. Northwestern Medicine's culturally targeted Hispanic Kidney Transplant Program (HKTP) was found to increase LDKTs in Hispanic patients at 1 of 2 transplant programs with greater implementation fidelity. METHODS We conducted a budget impact analysis to evaluate HKTP's impact on program financial profiles from changes in volume of LDKTs and deceased donor kidney transplants (DDKTs) in 2017 to 2019. We estimated HKTP programmatic costs, and kidney transplant (KT) program costs and revenues. We forecasted transplant volumes, HKTP programmatic costs, and KT program costs and revenues for 2022-2024. RESULTS At both programs, HKTP programmatic costs had <1% impact on total KT program costs, and HKTP programmatic costs comprised <1% of total KT program revenues in 2017-2019. In particular, the total volume of Hispanic KTs and HKTP LDKTs increased at both sites. Annual KT program revenues of HKTP LDKTs and DDKTs increased by 226.9% at site A and by 1042.9% at site B when comparing 2019-2017. Forecasted HKTP LDKT volume showed an increase of 36.4% (site A) and 33.3% (site B) with a subsequent increase in KT program revenues of 42.3% (site A) and 44.3% (site B) among HKTP LDKTs and DDKTs. CONCLUSIONS HKTP programmatic costs and KT evaluation costs are potentially recoverable by reimbursement of organ acquisition costs and offset by increases in total KT program revenues of LDKTs; transplant programs may find implementation of the HKTP financially manageable.

Abstract
BackgroundIn this study, the Keynesian principle “savings may be used as investments in resources” is applied to Kidney Transplantation (KT), contextualizing the whole Organs Donation and Transplantation (ODT) service as a unique healthcare entity. Our aim was to define the financial resources that may be acquired in the form of savings from the KT activity.MethodsWe analyzed registry and funding data for ODT in our region, between 2015 and 2019. Our hypotheses aimed to evaluate whether the savings would offset the Organ Donation (OD) costs, define the scope for growth, and estimate what savings could be generated by higher KT activity. To facilitate the evaluation of the resources produced by KT, we defined a coefficient generated from the combination of clinical outcomes, activity, and costs.ResultsThe ODT activity reached a peak in 2017, declining through 2018–2019. The savings matured in 2019 from the KT activity exceeded €15 million while the OD costs were less than €9 million. The regional KT activity was superior to the national average but inferior to international benchmarks. The estimated higher KT activity would produce savings between €16 and 20 million.ConclusionThe financial resources produced by KT contribute to defining a comprehensive perspective of ODT finance. The optimization of the funding process may lead to the financial self-sufficiency of the ODT service. The reproducible coefficient allows a reliable estimate of savings, subsequently enabling adequate investments and budgeting. Applying such a perspective jointly with reliable estimates would establish the basis for an in-hospital fee-for-value funding methodology for ODT.

Abstract
BACKGROUND Increasing prior authorization (PA) requirements for immunosuppression remain a burden for solid organ transplant (SOT) recipients and transplant staff. The objective of this study was to evaluate the number of PAs required and the approval rates at an academic, urban transplant center. METHODS This was a retrospective study of SOT recipients at the University of Illinois Hospital and Health Sciences System (UI Health) that required PAs between 11/1/2019 and 12/1/2020. Inclusion criteria were SOT recipients greater than 18 years of age and prescribed a medication by the transplant team that required PA. Duplicate PA requests were excluded from the analysis. RESULTS A total of 879 PAs were included in the study. Of these PAs, 85% (747/879) were approved. Seventy-four percent of the denials were overturned by an appeal. Most PAs were in black (45.4%), kidney transplant (62%), Medicare (31.7%), and Medicaid recipients (33.2%). The median approval time was 1 day for PAs and 5 days for appeals. Tacrolimus extended release (XR) (35.4%), tacrolimus immediate release (IR) (9.7%),and mycophenolic acid (7%) required most PAs. Black recipients and immunosuppression were identified as predictors of eventual PA approval, whereas recipients with Medicaid were less likely to obtain approval. CONCLUSIONS At our transplant center, there was a high approval rate of PAs for immunosuppression, which calls into question the utility of PAs in this patient population, where these medications are standard of care. More black recipients and patients with Medicare and Medicaid had increased PA requirements, highlighting further disparities within the current system.

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
Cardiorenal syndrome (CRS) is an increasingly recognized diagnostic entity associated with high morbidity and mortality among acutely ill heart failure (HF) patients with acute and/ or chronic kidney diseases (CKD). While traditionally viewed as a state of decline in glomerular filtration rate (GFR) due to decreased renal perfusion, mainly due to therapeutic interventions to relieve congestive in HF, recent insights into the underlying pathophysiologic mechanisms of CRS led to a broader definition and further classification of CRS into 5 distinct types. In this comprehensive review, we discuss the classification of CRS, highlighting the underlying common pathogenetic pathways of heart failure and kidney injury, including increased congestion, neurohormonal dysregulation, oxidative stress as well as inflammation, and cytokine storm that are particularly evident in COVID-19 patients with multiorgan failure and also in those with other disorders including sepsis, systemic lupus erythematosus and amyloidosis. In this review we also present the recent advances in the diagnostic strategies of CRS including cardiac and renal biomarkers as well as advanced cardiac and renal imaging techniques that are available to aid in the diagnosis as well as in the prognostication of this disorder. Finally, we discuss the various therapeutic options available to-date, including fluid optimization, hemofiltration, renal replacement therapy as well as the role of SGLT2 inhibitors in light of recent data from RCTs. It is important to note that, CRS population are either excluded or underrepresented, at best, in major RCTs and therefore, therapeutic recommendations are largely extrapolated from HF and CKD clinical trials.

Abstract
BACKGROUND Rising incidence and prevalence of end-stage renal disease is a worldwide concern for sustainability of healthcare systems and societies. Living donor renal transplant [LDRT] provides highest health achievements and cost containment than any alternative form of renal replacement therapy. Nonetheless, about 25% of potential LDRTs are missed for causes directly related with inadequate timing in donor assessment. Our quality improvement (QI) project implement process control tools and strategy aiming at reducing total evaluation time for donor candidates and minimizing dialysis exposure for intended recipients, which are the two main determinants of clinical outcomes and costs. METHODS The study includes patients who underwent donor nephrectomy between January 1, 2017 and December 31, 2021. Six Sigma DMAIC approach was adopted to assess Base Case performance (Jan2017-Jun2019) and to design and implement our QI project. Study of current state analysis focused on distribution of time intervals within the assessment process, analysis of roles and impacts of involved healthcare providers and identification of targets of improvement. Improved Scenario (Jul2019-Dec2021) was assessed in terms of total lead time reduction, total pre-transplantation dialysis exposure and costs reduction, and increase in pre-emptive transplantations. The study was reported following SQUIRE 2.0 Guidelines for QI projects. RESULTS Study population includes 63 patients, 37 in Base Case and 26 in Improved Scenario. Total lead time reduced from a median of 293 to 166 days and this in turn reduced pre-transplantation dialysis exposure and costs by 45%. Rate of potential pre-emptive donors' loss changes from 44% to 27%. CONCLUSIONS Lean methodology is an effective tool to improve quality and efficiency of healthcare processes, in the interest of patients, healthcare professionals and payers.

Abstract
BACKGROUND Various interventions are reportedly effective in promoting organ donor registration. However, the identity of those who best serve as presenters to appeal to the general public is not known. METHODS A campaign for organ donor registration was conducted through a local newspaper advertisement in Japan. The advertisement appeared in 439,733 copies of the newspaper on January 9, 2021. In addition to the main message, 6 different presenters with photos of their faces and quick response codes were listed in the advertisement, namely a urologist, transplant physician, nephrologist, dialysis physician, ophthalmologist, and kidney transplant recipient who was a nephrologist himself (ie, a recipient and nephrologist). Newspaper readers watched each video about deceased organ donation via the quick response codes, and the number of video views acquired 30 days after the appearance was the main outcome, which was assessed using YouTube analytics. The proportions (95% CI) of people who watched each video among 439,733 newspaper readers were compared among the 6 presenters. RESULTS The analyzed videos were viewed 262 times. The video produced by the recipient and nephrologist had the highest number of views among the 6 presenters (proportion: 0.019% [95% CI, 0.015-0.023]), followed by the one produced by the dialysis physician (0.011% [95% CI, 0.008-0.014]), the nephrologist (0.010% [95% CI, 0.007-0.014]), the urologist (0.008% [95% CI, 0.006-0.012]), the transplant physician (0.006% [95% CI, 0.004-0.009]), and the ophthalmologist (0.005% [95% CI, 0.004-0.008]). CONCLUSIONS The appeal by the recipient and the nephrologist reached the highest proportion of people who watched the video about deceased organ donation in Japan.

Abstract
PURPOSE OF REVIEW Kidney transplant failure results in significant patient morbidity and mortality, increased financial burden and exacerbates the organ shortage faced by kidney transplant candidates. The different strategies to maximize graft survival in kidney transplant recipients is presented in this review. RECENT FINDINGS Maximizing kidney graft survival requires optimizing immunosuppression, preventing and managing recurrent disease and using general chronic kidney disease strategies to slow allograft injury. Herein, we review: 1) strategies to tailor immunosuppression to the individual patient to avoid over and underimmunosuppression, and avoid immunosuppression-related drug toxicities, 2) latest findings in the following recurrent diseases: focal segmental glomerulosclerosis, membranous nephropathy, complement-mediated kidney disease and monoclonal gammopathy of renal significance, and, 3) approaches to slow allograft injury including BP control, and the use of antiproteinuric agents and SGLT-2 inhibitors. SUMMARY The last two decades has seen significant improvement in allograft outcomes resulting from advances in immunosuppression. With the federal government's renewed focus on kidney disease and transplantation, and recent advances in biomarkers, genetic testing, big data analytics and machine learning, we hope to see further outcome improvements in the next decade.

Ashiku L, Dagli C. Identify Hard-to-Place Kidneys for Early Engagement in Accelerated Placement With a Deep Learning Optimization Approach. Transplant Proc 2023; 55:38-48. [PMID: 36641350 DOI: 10.1016/j.transproceed.2022.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2022] [Accepted: 12/07/2022] [Indexed: 01/13/2023]
Abstract
Recommended practices that follow match-run sequences for hard-to-place kidneys succumb to many declines, accruing cold ischemic time and exacerbating kidney quality that may lead to unnecessary kidney discard. Hard-to-place deceased donor kidneys accepted and transplanted later in the match-run sequence may threaten higher graft failure rates. Accelerated placement is a practice for organ procurement organizations (OPOs) to allocate high-risk kidneys out of sequence and reach patients at aggressive transplant centers. The current practice of assessing hard-to-place kidneys and engaging in accelerated kidney placements relies heavily on the kidney donor profile index (KDPI) and the number of declines. Although this practice is reasonable, it also accrues cold ischemic time and increases the risk for kidney discard. We use a deep learning optimization approach to quickly identify kidneys at risk for discard. This approach uses Organ Procurement and Transplantation Network data to model kidney disposition. We filter discards and develop a model to predict transplant and discard of recovered and not transplanted kidneys. Kidneys with a higher probability of discard are deemed hard-to-place kidneys, which require early engagement for accelerated placement. Our approach will aid in identifying hard-to-place kidneys before or after procurement and support OPOs to deviate from the match-run for accelerated placement. Compared with the KDPI-only prediction of the kidney disposition, our approach demonstrates a 10% increase in correctly predicting kidneys at risk for discard. Future work will include developing models to identify candidates with an increased benefit from using hard-to-place kidneys.

Abstract
INTRODUCTION Renal transplantation remains the definitive treatment for end-stage renal disease. Currently employed minimally invasive techniques include robotic-assisted laparoscopy and laparoscopy. This study aims to determine whether either method provides an advantage. METHODS Following PRISMA guidelines, a systematic review was conducted. Data were analysed using Review Manager 5.3. RESULTS A total of 12 studies were included. Operative time and operative bleeding were similar between both approaches, with a mean difference (MD) of 16min (95% confidence interval (CI) -4.06, 37.38; p = 0.11) and 10.44ml (95% CI -43.89, 64.78; p = 0.71), respectively. Robotics had longer warm ischemia time (MD 1.14min; 95% CI 0.65, 1.63; p = 0.00001) but reduced length of stay (LOS) (MD -0.23days; 95% CI -0.45, -0.01; p = 0.04) and pain (MD -1.26 VAS; 95% CI -1.77, 0.75). Similar complication and conversion rates were seen among groups. CONCLUSIONS Robotic approaches provide a viable alternative to laparoscopic surgery. Operative time, bleeding volumes, complications and conversion rates are similar between both techniques; apparent robotic advantages on LOS and Pain need to be better analysed by future studies.

Abstract
OBJECTIVE The aim of this review was to review the ethical and multidisciplinary clinical challenges facing trauma surgeons when resuscitating patients presenting with penetrating brain injury (PBI) and multicavitary trauma. BACKGROUND While there is a significant gap in the literature on managing PBI in patients presenting with multisystem trauma, recent data demonstrate that resuscitation and prognostic features for such patients remains poorly described, with trauma guidelines out of date in this field. METHODS We reviewed a combination of recent multidisciplinary evidence-informed guidelines for PBI and coupled this with expert opinion from trauma, neurosurgery, neurocritical care, pediatric and transplant surgery, surgical ethics and importantly our community partners. RESULTS Traditional prognostic signs utilized in traumatic brain injury may not be applicable to PBI with a multidisciplinary team approach suggested on a case-by-case basis. Even with no role for neurosurgical intervention, neurocritical care, and neurointerventional support may be warranted, in parallel to multicavitary operative intervention. Special considerations should be afforded for pediatric PBI. Ethical considerations center on providing the patient with the best chance of survival. Consideration of organ donation should be considered as part of the continuum of patient, proxy and family-centric support and care. Community input is crucial in guiding decision making or protocol establishment on an institutional level. CONCLUSIONS Support of the patient after multicavitary PBI can be complex and is best addressed in a multidisciplinary fashion with extensive community involvement.

Abstract
BACKGROUND Genome-based precision medicine strategies promise to minimize premature graft loss after renal transplantation, through precision approaches to immune compatibility matching between kidney donors and recipients. The potential adoption of this technology calls for important changes to clinical management processes and allocation policy. Such potential policy change decisions may be supported by decision models from health economics, comparative effectiveness research and operations management. OBJECTIVE We used a systematic approach to identify and extract information about models published in the kidney transplantation literature and provide an overview of the status of our collective model-based knowledge about the kidney transplant process. METHODS Database searches were conducted in MEDLINE, Embase, Web of Science and other sources, for reviews and primary studies. We reviewed all English-language papers that presented a model that could be a tool to support decision making in kidney transplantation. Data were extracted on the clinical context and modelling methods used. RESULTS A total of 144 studies were included, most of which focused on a single component of the transplantation process, such as immunosuppressive therapy or donor-recipient matching and organ allocation policies. Pre- and post-transplant processes have rarely been modelled together. CONCLUSION A whole-disease modelling approach is preferred to inform precision medicine policy, given its potential upstream implementation in the treatment pathway. This requires consideration of pre- and post-transplant natural history, risk factors for allograft dysfunction and failure, and other post-transplant outcomes. Our call is for greater collaboration across disciplines and whole-disease modelling approaches to more accurately simulate complex policy decisions about the integration of precision medicine tools in kidney transplantation.

Abstract
Introduction Antibody mediated rejection (ABMR) is the most common cause of long-term allograft loss in kidney transplantation (KT). Therefore, a low human leukocyte antigen (HLA) mismatch (MM) load is favorable for KT outcomes. Hitherto, serological or low-resolution molecular HLA typing have been adapted in parallel. Here, we aimed to identify previously missed HLA mismatches and corresponding antibodies by high resolution HLA genotyping in a living-donor KT cohort. Methods 103 donor/recipient pairs transplanted at the University of Leipzig Medical Center between 1998 and 2018 were re-typed using next generation sequencing (NGS) of the HLA loci -A, -B, -C, -DRB1, -DRB345, -DQA1, -DQB1, -DPA1, and -DPB1. Based on these data, we compiled HLA MM counts for each pair and comparatively evaluated genomic HLA-typing with pre-transplant obtained serological/low-resolution HLA (=one-field) typing results. NGS HLA typing (=two-field) data was further used for reclassification of de novo HLA antibodies as "donor-specific". Results By two-field HLA re-typing, we were able to identify additional MM in 64.1% (n=66) of cases for HLA loci -A, -B, -C, -DRB1 and -DQB1 that were not observed by one-field HLA typing. In patients with biopsy proven ABMR, two-field calculated MM count was significantly higher than by one-field HLA typing. For additional typed HLA loci -DRB345, -DQA1, -DPA1, and -DPB1 we observed 2, 26, 3, and 23 MM, respectively. In total, 37.3% (69/185) of de novo donor specific antibodies (DSA) formation was directed against these loci (DRB345 ➔ n=33, DQA1 ➔ n=33, DPA1 ➔ n=1, DPB1 ➔ n=10). Conclusion Our results indicate that two-field HLA typing is feasible and provides significantly more sensitive HLA MM recognition in living-donor KT. Furthermore, accurate HLA typing plays an important role in graft management as it can improve discrimination between donor and non-donor HLA directed cellular and humoral alloreactivity in the long range. The inclusion of additional HLA loci against which antibodies can be readily detected, HLA-DRB345, -DQA1, -DQB1, -DPA1, and -DPB1, will allow a more precise virtual crossmatch and better prediction of potential DSA. Furthermore, in living KT, two-field HLA typing could contribute to the selection of the immunologically most suitable donors.

Abstract
Background During transplantation, a kidney graft undergoes a cascade of pathological changes, referred to as ischemia-reperfusion injury (IRI), as it is incorporated into the bloodstream. Various studies have reported that retrograde reperfusion (RRP) leads to improved myocardial recovery and could reduce IRI in liver transplantation. This study investigated the effect of RRP in renal transplantation with a focus on reduction of kidney IRI. Methods Between December 2019 and July 2022, 15 consecutive kidney transplants were performed with retrograde venous reperfusion. To conduct a comparative study and to recruit a control group, 15 kidney transplants that had been performed in the same center by the same two surgeons were retrospectively analyzed. Differences between the two groups were considered statistically significant at P<0.05. Results The baseline characteristics of the two groups were statistically comparable (P>0.05). The surgical technique for kidney transplantation was the same in both groups. On the first postoperative day, polyuria was less pronounced in the RRP group (P<0.01). Serum creatinine and urea levels and estimated glomerular filtration rates on postoperative days 1, 4, 7, and 30 were lower in the RRP group (P<0.05). Conclusions Retrograde venous reperfusion of a kidney transplant, preceding antegrade arterial reperfusion, reduced the effects of renal parenchyma IRI. To validate the results of this study, it is necessary to conduct further studies on a larger cohort of patients with a longer follow-up period.

Abstract
In recent decades, the allocation policies of many countries have moved from center-based to patient-based approaches. The new French kidney allocation system (KAS) of donations after brain death for adult recipients, implemented in 2015, was principally designed to introduce a unified allocation score (UAS) to be applied locally for one kidney and nationally for the other and to replace regional borders by a new geographical model. The new KAS balances dialysis duration and waiting time to compensate for listing delays and provides more effective longevity matching between donors and recipients with better HLA and age matching. We report these changes, with their rationale and main results. Results show improved HLA matching for young recipients and more rapid access to transplant for older recipients. Young recipients also had better access to transplantation. Transplant access decreased for recipients aged 60-69 and required tuning of KAS parameters. In conclusion, our results strongly indicate that national or adequately broad geographic allocation areas, combined with multiplicative interactions between allocation criteria, permit multivariate optimization of organ allocation and thus improve national kidney sharing and balance HLA matching and age matching, at the price of longer cold ischemic times and more logistical constraints than with local allocation.

Abstract
This Guide for Living Donor Kidney Transplantation (LDKT) has been prepared with the sponsorship of the Spanish Society of Nephrology (SEN), the Spanish Transplant Society (SET), and the Spanish National Transplant Organization (ONT). It updates evidence to offer the best chronic renal failure treatment when a potential living donor is available. The core aim of this Guide is to supply clinicians who evaluate living donors and transplant recipients with the best decision-making tools, to optimise their outcomes. Moreover, the role of living donors in the current KT context should recover the level of importance it had until recently. To this end the new forms of incompatible HLA and/or ABO donation, as well as the paired donation which is possible in several hospitals with experience in LDKT, offer additional ways to treat renal patients with an incompatible donor. Good results in terms of patient and graft survival have expanded the range of circumstances under which living renal donors are accepted. Older donors are now accepted, as are others with factors that affect the decision, such as a borderline clinical history or alterations, which when evaluated may lead to an additional number of transplantations. This Guide does not forget that LDKT may lead to risk for the donor. Pre-donation evaluation has to centre on the problems which may arise over the short or long-term, and these have to be described to the potential donor so that they are able take them into account. Experience over recent years has led to progress in risk analysis, to protect donors' health. This aspect always has to be taken into account by LDKT programmes when evaluating potential donors. Finally, this Guide has been designed to aid decision-making, with recommendations and suggestions when uncertainties arise in pre-donation studies. Its overarching aim is to ensure that informed consent is based on high quality studies and information supplied to donors and recipients, offering the strongest possible guarantees.

Abstract
INTRODUCTION Transplantation from controlled donation after circulatory determination of death (cDCD) is a new practice in France. An additional specific consent is required for registration on the cDCD waiting list. The aim of this study is to evaluate the impact of cDCD acceptance on the waiting time for the registered patients on the transplant list. METHODS Patients registered on the kidney transplant waiting list for a Death Brain Donor (DBD) kidney transplant between 2018 and 2019 in our center were included. Patients who were candidates for a second kidney transplant or who had already received an organ transplant were not included. The cDCD waiting list registration was authorized by a signed consent of the patient on the day of DBD registration. The primary endpoint was time to renal transplantation. RESULTS Of the 315 patients eligible for a cDCD graft at transplant list registration, 152 were registered on the cDCD waiting list. Time to transplantation for these patients was multiplied by 1.42 (95%CI 1.07-1.87) compared with patients not registered for a cDCD graft. The time to transplantation was 2.59 months (95%CI 0.49-4.69) shorter for a 2-year follow-up for cDCD-listed patients. This represents one additional transplant at 6 months for every seven registered patients. CONCLUSION cDCD waiting list registration reduced the time to kidney transplantation in France.

Abstract
RESUMO Introdução: Determinar precisamente a taxa de filtração glomerular (TFG) é crucial para seleção de doadores de rim. Métodos de medicina nuclear são considerados precisos na medição da TFG, mas nem sempre estão facilmente disponíveis. As fórmulas Modification of Diet in Renal Disease de 4 variáveis (MDRD4), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), e Full Age Spectrum (FAS) são equações comuns para estimar a TFG, sendo recomendadas para avaliação inicial dos doadores. Este estudo visou avaliar o desempenho destas equações de estimativa da TFG em comparação com o clearance do tecnécio-99m-ácido dietilenotriaminopentacético ([99mTc]Tc-DTPA). Métodos: Comparamos a TFG por clearance de [99mTc]Tc-DTPA usando um método com duas amostras de sangue com estimativa da TFG pelas equações MDRD4, CKD-EPI e FAS baseadas em creatinina em uma população de potenciais doadores saudáveis. Resultados: Incluiu-se 195 potenciais doadores de rim (68,2% mulheres; idade média de 49 anos, intervalo 21–75 anos). A TFG média medida por [99mTc]Tc-DTPA foi 101,5 ± 19,1 mL/min/1,73m2. As três equações subestimaram o valor da TFG medida por [99mTc]Tc-DTPA (MDRD4: –11,5 ± 18,8 mL/min/1,73 m2; CKD-EPI: –5,0 ± 17,4 mL/min/1,73 m2; FAS: –8,3 ± 17,4 mL/min/1,73 m2). A precisão dentro de 30% e 10% do valor da TFG medida foi maior para CKD-EPI. Conclusão: A equação CKD-EPI mostrou melhor desempenho na estimativa da TFG em potenciais doadores de rim saudáveis, revelando-se uma ferramenta mais precisa na avaliação inicial dos doadores. Entretanto, equações baseadas em creatinina tendem a subestimar a função renal. Portanto, a TFG deve ser confirmada por outro método em potenciais doadores.

Diabetes-free survival among living kidney donors and non-donors with obesity: A longitudinal cohort study. PLoS One 2022; 17:e0276882. [PMID: 36399462 PMCID: PMC9674148 DOI: 10.1371/journal.pone.0276882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2022] [Accepted: 10/13/2022] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND Approval of living kidney donors (LKD) with end-stage kidney disease (ESKD) risk factors, such as obesity, has increased. While lifetime ESKD development data are lacking, the study of intermediate outcomes such as diabetes is critical for LKD safety. Donation-attributable diabetes risk among persons with obesity remains unknown. The purpose of this study was to evaluate 10-year diabetes-free survival among LKDs and non-donors with obesity. METHODS This longitudinal cohort study identified adult, LKDs (1976-2020) from 42 US transplant centers and non-donors from the Coronary Artery Risk Development in Young Adults (1985-1986) and the Atherosclerosis Risk in Communities (1987-1989) studies with body mass index ≥30 kg/m2. LKDs were matched to non-donors on baseline characteristics (age, sex, race, body mass index, systolic and diastolic blood pressure) plus diabetes-specific risk factors (family history of diabetes, impaired fasting glucose, smoking history). Accelerated failure time models were utilized to evaluate 10-year diabetes-free survival. FINDINGS Among 3464 participants, 1119 (32%) were LKDs and 2345 (68%) were non-donors. After matching on baseline characteristics plus diabetes-specific risk factors, 4% (7/165) LKDs and 9% (15/165) non-donors developed diabetes (median follow-up time 8.5 (IQR: 5.6-10.0) and 9.1 (IQR: 5.9-10.0) years, respectively). While not significant, LKDs were estimated to live diabetes-free 2 times longer than non-donors (estimate 1.91; 95% CI: 0.79-4.64, p = 0.15). CONCLUSIONS LKDs with obesity trended toward living longer diabetes-free than non-donors with obesity, suggesting within the decade following donation there was no increased diabetes risk among LKDs. Further work is needed to evaluate donation-attributable diabetes risk long-term.

Abstract
UNLABELLED The acceptability and impact of eHealth on patient outcomes may be limited if their concerns and priorities are not addressed. This study aimed to describe the perspectives and experiences of eHealth among kidney transplant recipients. METHODS Face-to-face semistructured interviews were conducted with 30 adult kidney transplant recipients from New South Wales, Australia (urban and regional), in ambulatory clinics. We used purposive sampling to obtain a wide range of demographic and clinical characteristics. Transcripts were analyzed thematically. Ethics was approved by the Western Sydney Local Health District (6054-2019/ETH08718). FINDINGS Six themes were identified: seeking access to quality care (prioritizing and trusting clinician advice, better safety and timeliness, enabled by user-friendly content); supporting self-management (responsive to individualized informational need, empowerment through practical knowledge, encouraging connectedness); assessing reliability and trustworthiness (discerning information integrity, applying to own context, apprehensive about privacy and confidentiality); enhancing health system capabilities (synergy with routine consultations, essential to coordination, achieving goals by real-time monitoring); technology burden and limitation (uncertainty with navigation and comprehension, challenged by technical difficulties, requiring additional preparation, confrontation and distress); and lacking applicable value (diminished assurance of medical services, existing practice and procedures, hampered by low expectations and disinterest). CONCLUSION Recipients felt eHealth could support healthcare delivery and self-management activities. However, they encountered challenges in navigating technology and were concerned about privacy, confidentiality, and misinformation. eHealth that is accessible, individualized, and secure may improve patient satisfaction and outcomes.

Abstract
INTRODUCTION Since 2012, a deceased donor kidney transplant program exists for dialysis patients living in New-Caledonia in collaboration with Royal Prince Alfred Hospital in Sydney, Australia. This program has reduced the time spent out-of-territory for a renal transplantation and has reduced the economic burden of end stage renal disease in New-Caledonia. We have realised a photography of kidney transplants evaluation for patients in peritoneal dialysis in New-Caledonia and Wallis and Futuna. The first aim was to describe access to kidney transplants evaluation for dialysis patients. A second aim was to compare patients with a conformed kidney transplant evaluation and patients without transplant evaluation with no obvious reasons identified. METHOD All patients in peritoneal dialysis in New-Caledonia and Wallis and Futuna at the 2018, 31st july were included. A standardised form was filled by two nephrologists. The computerised shared medical record was used to collect information. A kidney transplant evaluation was adequate for patients registered on transplant waiting list, patients with medical contraindications identified or patients with evaluation exams begun less than 6 months. RESULTS In total, 61 patients were included. The average age was 62 years old. The chronic kidney disease care average time was 6.7 years and the dialysis average time was 2.0 years. Among them, 11 (18 %) were registered on the waiting list, 26 (43 %) had at least one kidney transplant medical contraindication, 3 (5 %) had begun transplant exam since less than 6 months and 21 (34 %) had no transplant exam begun or transplant exam begun since more than 6 months without medical contraindication identified. Among those 21 patients, the three most common reasons were a faulty programming transplant exam (67 %; n = 14), a remote living place (48 %; n = 10) and an intercurrent health event (29 %; n = 6). Among patients living in Noumea and suburbs, 74 % had a conformed transplant evaluation against 44 % in patients living outside Noumea and suburbs (P = 0.058). Nearly one in two patients not on the waiting list had have no information about kidney graft or the information was not recorded in the medical record. CONCLUSION This study showed two main factors of a non-conformed transplantation evaluation: living outside Noumea and suburbs and a non-efficient planning of pre-transplant assessment exams. There is also a lack of information to the patient. These risk factors for late registration and non-registration must be considered by the healthcare teams. This study will provide a point of reference to assess the impact of actions to improve access to renal transplantation deployed in New-Caledonia.

Abstract
Kidney transplantation is the best renal replacement therapy (medically and economically) for eligible patients with end-stage kidney disease. Studies in some French regions and in other countries suggest a lower access to the kidney transplant waiting listing and also to kidney transplantation, once waitlisted, for women. Using a mixed methods approach, this study aims to precisely understand these potential sex disparities and their causes. The quantitative study will explore the geographic disparities, compare the determinants of access to the waiting list and to kidney transplantation, and compare the reasons and duration of inactive status on the waiting list in women and men at different scales (national, regional, departmental, and census-block). The qualitative study will allow describing and comparing women's and men's views about their disease and transplantation, as well as nephrologists' practices relative to the French national guidelines on waiting list registration. This type of study is important in the current societal context in which the reduction of sex/gender-based inequalities is a major social expectation.

The Enhanced Recovery after Surgery (ERAS) Pathway Is a Safe Journey for Kidney Transplant Recipients during the "Extended Criteria Donor" Era. Pathogens 2022; 11:pathogens11101193.

Abstract
Enhanced recovery after surgery (ERAS) protocols are still underused in kidney transplantation (KT) due to recipients’ “frailty” and risk of postoperative complications. We aimed to evaluate the feasibility and safety of ERAS in KT during the “extended-criteria donor” era, and to identify the predictive factors of prolonged hospitalization. In 2010−2019, all patients receiving KT were included in ERAS program targeting a discharge home within 5 days of surgery. Recipient, transplant, and outcomes data were analyzed. Of 454 KT [male: 280, 63.9%; age: 57 (19−77) years], 212 (46.7%) recipients were discharged within the ERAS target (≤5 days), while 242 (53.3%) were discharged later. Patients within the ERAS target (≤5 days) had comparable recipient and transplant characteristics to those with longer hospital stays, and they had similar post-operative complications, readmission rates, and 5 year graft/patient survival. In the multivariate analysis, DGF (HR: 2.16, 95% CI: 1.08−4.34, p < 0.030) and in-hospital dialysis (HR: 3.68, 95% CI: 1.73−7.85, p < 0.001) were the only predictive factors for late discharge. The ERAS approach is feasible and safe in all KT candidates, and its failure is primarily related to the postoperative graft function, rather than the recipient’s clinical status. ERAS pathways, integrated with strict collaboration with local nephrologists, allow early discharge after KT, with clinical benefits.

Abstract
BACKGROUND Consensus guidelines advise simultaneous heart kidney transplantation (SHK) in heart candidates with an estimated glomerular filtration rate (eGFR) of <30 mL/min/1.73 m 2 . We hypothesize that a significant fraction of such patients would not need an SHK, even though a graded increase in mortality and end-stage kidney disease (ESKD) would be seen with decrements in eGFR. METHODS United Network of Organ Sharing data for isolated heart transplants between 2000 and 2020 were divided into two groups based on eGFR at transplant (≤20 mL/min/1.73 m 2 and 21-29 mL/min/1.73 m 2 ). The primary outcome was mortality and secondary outcome was ESKD posttransplant. Cox regression and cumulative incidence competing risk methods were used to compare risk of mortality and ESKD. RESULTS There was no difference in mortality (adjusted hazard ratio [aHR] 0.82 [95% confidence interval, CI: 0.60-1.11, P = 0.21]) or ESKD (aHR 1.01 [95% CI: 0.49-2.09, P = 0.96]) between the two groups (≤20 versus 21-29). The overall incidence of ESKD for the entire cohort at 1, 5, and 10 y were 1.5%, 9.5%, and 20%. CONCLUSIONS Although risk of ESKD is highest in heart candidates with an eGFR <30 mL/min/1.73 m 2 , <10% of patients reach ESKD within 5 y' and most will recover significant renal function posttransplant. More refined selection criteria are required to identify candidates for SHK.

Abstract
Purpose of Review The goal of deceased donor kidney allocation policy is to provide objective prioritization for donated kidneys, and policy has undergone a series of revisions in the past decade in attempt to achieve equity and utility in access to kidney transplantation. Most recently, to address geographic disparities in access to kidney transplantation, the Kidney Allocation System changed to a distance-based allocation system—colloquially termed “KAS 250”—moving away from donor service areas as the geographic basis of allocation. We review the early impact of this policy change on access to transplant for patients, and on complexity of organ allocation and transplantation for transplant centers and organ procurement organizations. Recent Findings Broader sharing of kidneys has increased complexity of the allocation system, as transplant centers and OPOs now interact in larger networks. The increased competition resulting from this system, and the increased operational burden on centers and OPOs resulting from greater numbers of organ offers, may adversely affect organ utilization. Preliminary results suggest an increase in transplant rate overall but a trend toward higher kidney discard and increased cold ischemia time. Summary The KAS 250 allocation policy changed the geographic basis of deceased donor kidney distribution in a manner that is intended to reduce geographic disparities in access to kidney transplantation. Close monitoring of this policy’s impact on patients, transplant center behavior, and process measures is critical to the aim of maximizing access to transplant while achieving transplant equity.

An ex-ante cost-utility analysis of the deemed consent legislation compared to expressed consent for kidney transplantations in Nova Scotia. COST EFFECTIVENESS AND RESOURCE ALLOCATION 2022; 20:55. [PMID: 36199099 PMCID: PMC9535887 DOI: 10.1186/s12962-022-00390-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2022] [Accepted: 09/14/2022] [Indexed: 11/18/2022] Open
Abstract
Background This study was an ex-ante cost-utility analysis of deemed consent legislation for deceased organ donation in Nova Scotia, a province in Canada. The legislation became effective in January 2021. The study's objective was to assess the conditions necessary for the legislation change’s cost-effectiveness compared to expressed consent, focusing on kidney transplantation (KT). Method We performed a cost-utility analysis using a Markov model with a lifetime horizon. The study was from a Canadian payer perspective. The target population was patients with end-stage kidney disease (ESKD) in Atlantic Canada waitlisted for KT. The intervention was the deemed consent and accompanying health system transformations. Expressed consent (before the change) was the comparator. We simulated the minimum required increase in deceased donor KT per year for the cost-effectiveness of the deemed consent. We also evaluated how changes in dialysis and maintenance immunosuppressant drug costs and living donor KT per year impacted cost-effectiveness in sensitivity analyses. Results The expected lifetime cost of an ESKD patient ranged from $177,663 to $553,897. In the deemed consent environment, the expected lifetime cost per patient depended on the percentage increases in the proportion of ESKD patients on the waitlist getting a KT in a year. The incremental cost-utility ratio (ICUR) increased with deceased donor KT per year. Cost-effectiveness of deemed consent compared to expressed consent required a minimum of a 1% increase in deceased donor KT per year. A 1% increase was associated with an ICUR of $32,629 per QALY (95% CI: − $64,279, $232,488) with a 81% probability of being cost-effective if the willingness-to-pay (WTP) was $61,466. Increases in dialysis and post-KT maintenance immunosuppressant drug costs above a threshold impacted value for money. The threshold for immunosuppressant drug costs also depended on the percent increases in deceased donor KT probability and the WTP threshold. Conclusions The deemed consent legislation in NS for deceased organ donation and the accompanying health system transformations are cost-effective to the extent that they are anticipated to contribute to more deceased donor KTs than before, and even a small increase in the proportion of waitlist patients receiving a deceased donor KT than before the change represents value for money.

Abstract
Understanding and communicating the risk of pregnancy complications post-living kidney donation is imperative as the majority of living kidney donors (LKD) are women of childbearing age. We aimed to identify all original research articles examining complications in post-donation pregnancies and compared the quality and consistency of related guidelines. We searched Embase, MEDLINE, PubMed, society webpages, and guideline registries for English-language publications published up until December 18, 2020. Ninety-three articles were screened from which 16 studies were identified, with a total of 1399 post-donation pregnancies. The outcome of interest, post-donation pregnancy complications, was not calculable, and only a narrative synthesis of the evidence was possible. The absolute risk of pre-eclampsia increased from ~1%-3% pre-donation (lower than the general population) to ~4%-10% post-donation (comparable to the general population). The risks of adverse fetal and neonatal outcomes were no different between post-donation and pre-donation pregnancies. Guidelines and consensus statements were consistent in stating the need to inform LKDs of their post-donation pregnancy risk, however, the depth and scope of this guidance were variable. While the absolute risk of pregnancy complications remains low post-donation, a concerted effort is required to better identify and individualize risk in these women, such that consent to donation is truly informed.

Abstract
Resumo Entre as terapias renais substitutivas, o transplante renal preemptivo (TRP) apresenta os melhores resultados clínicos, sociais e econômicos. No entanto, ainda é raramente escolhido como primeira terapia para pacientes com falência renal irreversível. Foram desenvolvidas iniciativas em diferentes partes do mundo para identificar as razões pelas quais o TRP ainda não é amplamente utilizado e para facilitar o acesso de pacientes com doença renal em estágio terminal às vantagens associadas ao mesmo. Este artigo aborda as principais vantagens e dificuldades do TRP e discute quando ele deve ser indicado e como preparar potenciais receptores para o TRP.

Managing the Costs of Routine Follow-up Care After Living Kidney Donation: a Review and Survey of Contemporary Experience, Practices, and Challenges. CURRENT TRANSPLANTATION REPORTS 2022; 9:328-335. [PMID: 36187071 PMCID: PMC9510404 DOI: 10.1007/s40472-022-00379-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 08/12/2022] [Indexed: 11/12/2022]
Abstract
Purpose of Review While living organ donor follow-up is mandated for 2 years in the USA, formal guidance on recovering associated costs of follow-up care is lacking. In this review, we discuss current billing practices of transplant programs for living kidney donor follow-up, and propose future directions for managing follow-up costs and supporting cost neutrality in donor care. Recent Findings Living donors may incur costs and financial risks in the donation process, including travel, lost time from work, and dependent care. In addition, adherence to the Organ Procurement and Transplantation Network (OPTN) mandate for US transplant programs to submit 6-, 12-, and 24-month postdonation follow-up data to the national registry may incur out-of-pocket medical costs for donors. Notably, the Centers for Medicare and Medicaid Services (CMS) has explicitly disallowed transplant programs to bill routine, mandated follow-up costs to the organ acquisition cost center or to the recipient’s Medicare insurance. We conducted a survey of transplant staff in the USA (distributed October 22, 2020–March 15, 2021), which identified that the mechanisms for recovering or covering the costs of mandated routine postdonation follow-up at responding programs commonly include billing recipients’ private insurance (40%), while 41% bill recipients’ Medicare insurance. Many programs reported utilizing institutional allowancing (up to 50%), and some programs billed the organ acquisition cost center (25%). A small percentage (11%) reported billing donors or donors’ insurance. Summary To maintain a high level of adherence to living donor follow-up without financially burdening donors, up-to-date resources are needed on handling routine donor follow-up costs in ways that are policy-compliant and effective for donors and programs. Development of a government-supported national living donor follow-up registry like the Living Donor Collective may provide solutions for aspects of postdonation follow-up, but requires transplant program commitment to register donors and donor candidates as well as donor engagement with follow-up outreach contacts after donation.

Abstract
BACKGROUND Treatment burden refers to the work involved in managing one's health and its impact on well-being and has been associated with nonadherence in patients with chronic illnesses. No kidney transplant (KT)-specific measure of treatment burden exists. The aim of this study was to develop a KT-specific supplement to the Patient Experience with Treatment and Self-Management (PETS), a general measure of treatment burden. METHODS After drafting and pretesting KT-specific survey items, we conducted a cross-sectional survey study involving KT recipients from Mayo Clinic in Minnesota, Arizona, and Florida. Exploratory factor analysis (EFA) was used to identify domains for scaling the KT-specific supplement. Construct and known-groups validity were determined. RESULTS Survey respondents (n = 167) had a mean age of 61 years (range 22-86) and received a KT on average 4.0 years ago. Three KT-specific scales were identified (transplant function, self-management, adverse effects). Higher scores on the KT-specific scales were correlated with higher PETS treatment burden, worse physical and mental health, and lower self-efficacy (p < 0.0001). Patients taking more medications reported higher transplant self-management burden. CONCLUSIONS We developed a KT-specific supplement to the PETS general measure of treatment burden. Scores may help providers identify recipients at risk for nonadherence.

Pregnancies and Gynecological Follow-Up after Solid Organ Transplantation: Experience of a Decade. J Clin Med 2022; 11:jcm11164792. [PMID: 36013030 PMCID: PMC9409658 DOI: 10.3390/jcm11164792] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 08/09/2022] [Accepted: 08/13/2022] [Indexed: 11/17/2022] Open
Abstract
In recent years, solid organ transplantations, such as kidney or lung grafts, have been performed worldwide with an improvement of quality of life under immunosuppressive therapy and an increase in life expectancy, allowing young women to consider childbearing. In the current study, we conduct a retrospective study in two French centers for kidney and lung transplantations to evaluate the rate and outcomes of pregnancies, contraception and gynecological monitoring for women under 40 years old who underwent solid organ transplantation. Among 210 women, progestin was the most widely used contraceptive method. Of the 210 women, 24 (11.4%) conceived 33 pregnancies of which 25 (75.8%) were planned with an immunosuppressant therapy switch. Of the 33 pregnancies, 7 miscarried (21.2%) and 21 (63.7%) resulted in a live birth with a high rate of pre-eclampsia (50%). No graft rejections were observed during pregnancies. Among the deliveries, 19 were premature (90.5%, mostly due to induced delivery) and the C-section rate was high (52.4%). No particular pathology was identified among newborns. We conclude that pregnancies following solid organ transplantation are feasible, and while they are at an increased risk of pre-eclampsia and prematurity, they should still be permitted with close surveillance by a multidisciplinary care team.

Abstract
End-stage renal disease (ESRD) is characterized by racial inequity; Blacks are 3 times more likely to develop ESRD than Whites. Transplant is the preferred treatment option since transplanted patients experience better clinical outcomes. Racial inequities persist at each of the steps required for transplantation. Despite the vast literature describing these racial inequities, it does not include dialysis patients' awareness and understanding of treatment options, specifically for transplant. To address this gap, we purposely sampled Blacks in Detroit who were receiving dialysis and who were not active on any transplant waitlist to investigate their understanding and perceptions of transplants. We used uncertainty management theory (UMT) to better understand perceived barriers to getting and remaining on a transplant waitlist. We aimed to address a critical gap in the literature to inform approaches addressing this enduring inequity. For this qualitative study, we conducted individual, semi-structured interviews with 24 Black ESRD patients, aged 34-73 years: 9 male and 15 female. Participants shared their experiences of being on dialysis, perceptions, and understanding of transplants. We describe two key findings: 1) uncertainty for these patients is prevalent and multi-layered and 2) social support can both dissuade an individual from pursuing transplant (i.e., reluctance to ask family members to be donors) and it can result in decreasing uncertainty (e.g., participants wanting to pursue transplant to be with family). We highlight the specific need to improve patient education regarding treatment options and enhancing how relevant health information can be communicated.

Abstract
Background Chronic kidney disease (CKD) is a health problem due to its increasing prevalence and imposes a significant economic burden on the health system. This study aimed to analyze the cost–benefit of kidney transplantation through the valuation of patients with ESRD for a kidney transplant and its costs to help decide this regard. Material and methods This study was a descriptive-analytical and cross-sectional economic evaluation study of health interventions performed in Imam Khomeini Hospital in Urmia from the patient’s perspective. The records of kidney recipients were used to calculate the direct costs of kidney transplantation based on the government tariff rate in 2021. The willingness to pay for kidney transplantation (benefit) was measured through a questionnaire and with a contingent valuation method from 266 samples of patients with ESRD. The questionnaire designed by the researchers had four scenarios with different chances for kidney transplant success. Validation and test–retest methods were used to check the validity and reliability of the questionnaire. Stata software was used to estimate the regression of the factors affecting the willingness to pay and the kidney transplant demand function. Results The average cost of a kidney transplant was $877.4. The average willingness to pay for a kidney transplant for four scenarios was estimated at $4733. The mean cost–benefit ratio (BCR) and net present value (NPV) for the four kidney transplant scenarios were 5.39 and $3855. The variables of employment status, awareness of kidney function, number of years with ESRD, insurance coverage, and patients’ income significantly affected their willingness to pay. However, the effect of other variables was not significant. The absolute value of price elasticity of kidney transplant demand was also equal to 2.13. Conclusion According to the cost–benefit analysis indexes, the study results showed that a kidney transplant has a net positive benefit for all levels of its probability of success, so the willingness to pay or valuation of patients is about five times the cost of a kidney transplant. Also, the demand for kidney transplantation shows the high sensitivity of the demand for this service to the price. Therefore, preparations for kidney transplantation in patients with ESRD should be considered in situations where the price and cost of transplantation change. The results can help health policy-makers decide to allocate financial resources more efficiently.

Abstract
With the continuing disparity between organ supply to match the increasing demand for kidney transplants in patients with renal failure, donation after the circulatory determination of death (DCDD) has become an important and increasing global source of kidneys for clinical use. The concern that the outcomes of controlled DCDD donor kidney transplants were inferior to those obtained from donors declared dead by neurologic criteria has largely diminished because large-scale registry and single-center reports consistently have reported favorable outcomes. For uncontrolled DCDD kidney transplants, outcomes are correspondingly acceptable, although there is a greater risk of primary nonfunction. The potential of DCDD remains unrealized in many countries because of the ethical concerns and resource implications in the utilization of these donor kidneys for transplantation. In this review, we discuss the origin and definitions of DCDD donors, and examine the long-term outcomes of transplants from DCDD donor kidneys. We discuss the controversies, challenges, and ethical and legal barriers in the acceptance of DCDD, including the complexities of implementing and sustaining controlled and uncontrolled DCDD donor programs. The lessons learned from global leaders will assist a wider international recognition, acceptance, and development of DCDD transplant programs that will noticeably facilitate and address the global shortages of kidneys for transplantation, and ensure the opportunity for people who had indicated their desires to become organ donors fulfill their final wishes.

Abstract
IMPORTANCE Delayed graft function (DGF) is a risk factor for acute rejection and graft failure after kidney transplant. Previous studies have suggested that dexmedetomidine may be renoprotective, but whether the use of dexmedetomidine would improve kidney allograft function is unknown. OBJECTIVE To investigate the effects of perioperative dexmedetomidine on DGF following a donation-after-cardiac-death (DCD) kidney transplant. DESIGN, SETTING, AND PARTICIPANTS This single-center, double-blind, placebo-controlled randomized clinical trial was conducted at The First Affiliated Hospital of Soochow University in Suzhou, China. Adults (18 years or older) who were scheduled for DCD kidney transplant were enrolled between September 1, 2019, and January 28, 2021, and then randomized to receive either dexmedetomidine or normal saline (placebo). One-year postoperative outcomes were recorded. All analyses were based on the modified intention-to-treat population. INTERVENTIONS Patients who were randomized to the dexmedetomidine group received a 24-hour perioperative dexmedetomidine intravenous infusion (0.4 μg/kg/h intraoperatively and 0.1 μg/kg/h postoperatively). Patients who were randomized to the normal saline group received an intravenous infusion of the placebo with the same dose regimen as the dexmedetomidine. MAIN OUTCOMES AND MEASURES The primary outcome was the incidence of DGF, defined as the need for dialysis in the first posttransplant week. The prespecified secondary outcomes were in-hospital repeated dialysis in the first posttransplant week, in-hospital acute rejection, and serum creatinine, serum cystatin C, estimated glomerular filtration rate, need for dialysis, and patient survival on posttransplant day 30. RESULTS Of the 114 patients enrolled, 111 completed the study (mean [SD] age, 43.4 [10.8] years; 64 male patients [57.7%]), of whom 56 were randomized to the dexmedetomidine group and 55 to the normal saline group. Dexmedetomidine infusion compared with normal saline reduced the incidence of DGF (17.9% vs 34.5%; odds ratio [OR], 0.41; 95% CI, 0.17-0.98; P = .04) and repeated dialysis (12.5% vs 30.9%; OR, 0.32; 95% CI, 0.13-0.88; P = .02, which was not statistically significant after multiple testing corrections), without significant effect on other secondary outcomes. Dexmedetomidine vs normal saline infusion led to a higher median (IQR) creatinine clearance rate on postoperative days 1 (9.9 [4.9-21.2] mL/min vs 7.9 [2.0-10.4] mL/min) and 2 (29.6 [9.7-67.4] mL/min vs 14.6 [3.8-45.1] mL/min) as well as increased median (IQR) urine output on postoperative days 2 (106.5 [66.3-175.6] mL/h vs 82.9 [27.1-141.9] mL/h) and 7 (126.1 [98.0-151.3] mL/h vs 107.0 [82.5-137.5] mL/h) and at hospital discharge discharge (110.4 [92.8-121.9] mL/h vs 97.1 [77.5-113.8] mL/h). Three patients (5.5%) from the normal saline group developed allograft failure by the post hoc 1-year follow-up visit. CONCLUSIONS AND RELEVANCE This randomized clinical trial found that 24-hour perioperative dexmedetomidine decreased the incidence of DGF after DCD kidney transplant. The findings support the use of dexmedetomidine in kidney transplants. TRIAL REGISTRATION Chinese Clinical Trial Registry Identifier: ChiCTR1900025493.

Abstract
BACKGROUND The development of cytomegalovirus (CMV) infection after kidney transplant remains a significant cause of posttransplant morbidity, graft loss, and mortality. Despite appropriate antiviral therapy, recipients without previous CMV exposure can currently be allocated a kidney from a donor with previous CMV infection (D+R-) that carries the greatest risk of posttransplant CMV infection and associated complications. Preferential placement of CMV D- organs in negative recipients (R-) has been shown to reduce the risk of viral infection and associated complications. METHODS To assess the long-term survival and economic benefits of allocation policy reforms, a decision-analytic model was constructed to compare receipt of CMV D- with CMV D+ organ in CMV R- recipients using data from transplant registry, Medicare claims, and pharmaceutical costs. RESULTS For CMV R- patients, receipt of a CMV D- organ was associated with greater average survival (14.3 versus 12.6 y), superior quality-adjusted life years (12.6 versus 9.8), and lower costs ($529 512 versus $542 963). One-way sensitivity analysis demonstrated a survival advantage for patients waiting as long as 30 mo for a CMV D- kidney. CONCLUSIONS Altering national allocation policy to preferentially offer CMV D- organs to CMV R- recipients could improve survival and lower costs after transplant if appropriately implemented.
