Stewart D, Mupfudze T, Klassen D. Does anybody really know what (the kidney median waiting) time is? Am J Transplant 2023; 23:223-231. [PMID: 36695688 DOI: 10.1016/j.ajt.2022.12.005] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 11/10/2022] [Accepted: 12/05/2022] [Indexed: 01/13/2023]
Abstract
The median waiting time (MWT) to deceased donor kidney transplant is of interest to patients, clinicians, and the media but remains elusive due to both methodological and philosophical challenges. We used Organ Procurement and Transplantation Network data from January 2003 to March 2022 to estimate MWTs using various methods and timescales, applied overall, by era, and by candidate demographics. After rising for a decade, the overall MWT fell to 5.19 years between 2015 and 2018 and declined again to 4.05 years (April 2021 to March 2022), based on the Kaplan-Meier method applied to period-prevalent cohorts. MWTs differed markedly by blood type, donor service area, and pediatric vs adult status, but to a lesser degree by race/ethnicity. Choice of methodology affected the magnitude of these differences. Instead of waiting years for an answer, reliable kidney MWT estimates can be obtained shortly after a policy is implemented using the period-prevalent Kaplan-Meier approach, a theoretical but useful construct for which we found no evidence of bias compared with using incident cohorts. We recommend this method be used complementary to the competing risks approach, under which MWT is often inestimable, to fill the present information void concerning the seemingly simple question of how long it takes to get a kidney transplant in the United States.

Living Donor Kidney Transplantation in Older Individuals: An Ethical Legal and Psychological Aspects of Transplantation (ELPAT) View. Transpl Int 2023; 36:11139.

Abstract
Living donor transplantation is the optimal treatment for suitable patients with end-stage kidney disease. There are particular advantages for older individuals in terms of elective surgery, timely transplantation, and early graft function. Yet, despite the superiority of living donor transplantation especially for this cohort, older patients are significantly less likely to access this treatment modality than younger age groups. However, given the changing population demographic in recent decades, there are increasing numbers of older but otherwise healthy individuals with kidney disease who could benefit from living donor transplantation. The complex reasons for this inequity of access are explored, including conscious and unconscious age-related bias by healthcare professionals, concerns relating to older living donors, ethical anxieties related to younger adults donating to aging patients, unwillingness of potential older recipients to consider living donation, and the relevant legislation. There is a legal and moral duty to consider the inequity of access to living donor transplantation, recognising both the potential disparity between chronological and physiological age in older patients, and benefits of this treatment for individuals as well as society.

Abstract
Screening for occult coronary artery disease in potential kidney transplant recipients has become entrenched in current medical practice as the standard of care and is supported by national and international clinical guidelines. However, there is increasing and robust evidence that such an approach is out-dated, scientifically and conceptually flawed, ineffective, potentially directly harmful, discriminates against ethnic minorities and patients from more deprived socioeconomic backgrounds, and unfairly denies many patients access to potentially lifesaving and life-enhancing transplantation. Herein we review the available evidence in the light of recently published randomized controlled trials and major observational studies. We propose ways of moving the field forward to the overall benefit of patients with advanced kidney disease.

The probability of receiving a kidney transplantation in end-stage kidney disease patients who are treated with haemodiafiltration or haemodialysis: a pooled individual participant data from four randomised controlled trials. BMC Nephrol 2021; 22:70. [PMID: 33632160 PMCID: PMC7905891 DOI: 10.1186/s12882-021-02265-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 01/29/2021] [Indexed: 01/08/2023] Open
Abstract
Background Due to a critical shortage of available kidney grafts, most patients with Stage 5 Chronic Kidney Disease (CKD5) require bridging dialysis support. It remains unclear whether treatment by different dialysis modalities changes the selection and/or preparation of a potential transplant candidate. Therefore, we assessed whether the likelihood of receiving kidney transplant (both living or deceased kidney donors) differs between haemodialysis (HD) and online haemodiafiltration (HDF) in patients with CKD5D. Methods Individual participant data from four randomised controlled trials comparing online HDF with HD were used. Information on kidney transplant was obtained during follow-up. The likelihood of receiving a kidney transplant was compared between HD and HDF, and evaluated across different subgroups: age, sex, diabetes, history of cardiovascular disease, albumin, dialysis vintage, fistula, and level of convection volume standardized to body surface area. Hazard ratios (HRs), with corresponding 95% confidence intervals (95% CI), comparing the effect of online HDF versus HD on the likelihood of receiving a kidney transplant, were estimated using Cox proportional hazards models with a random effect for study. Results After a median follow-up of 2.5 years (Q1 to Q3: 1.9–3.0), 331 of the 1620 (20.4%) patients with CKD5D received a kidney transplant. This concerned 22% (n = 179) of patients who were treated with online HDF compared with 19% (n = 152) of patients who were treated with HD. No differences in the likelihood of undergoing a kidney transplant were found between the two dialysis modalities in both the crude analyse (HR: 1.07, 95% CI: 0.86–1.33) and adjusted analysis for age, sex, diabetes, cardiovascular history, albumin, and creatinine (HR: 1.15, 95%-CI: 0.92–1.44). There was no evidence for a differential effect across subgroups based on patient- and disease-characteristics nor in different categories of convection volumes. Conclusions Treatment with HD and HDF does not affect the selection and/or preparation of CKD5D patients for kidney transplant given that the likelihood of receiving a kidney transplant does not differ between the dialysis modalities. These finding persisted across a variety of subgroups differing in patient and disease characteristics and is not affected by the level of convection volume delivered during HDF treatment sessions.

Impact of cardiovascular risk stratification strategies in kidney transplantation over time. Nephrol Dial Transplant 2021; 35:1810-1818.

Abstract
BACKGROUND Kidney transplant recipients exhibit a dramatically increased cardiovascular (CV) risk. In 2007, Austrian centres implemented a consensus of comprehensive CV screening programme prior to kidney transplantation (KT). The consensus placed a particular emphasis on screening for coronary artery disease (CAD) with cardiac computed tomography (CT) or coronary angiography (CAG) in patients with diabetes mellitus, known CAD or those having multiple conventional CV risk factors. Here, we investigate if this affected risk stratification and post-transplant CV outcomes. METHODS In a retrospective chart review, we evaluated 551 KTs performed from 2003 to 2015 in our centre. Patients were categorized into three groups: KT before (2003-07), directly after (2008-11) and 5 years after (2012-15) implementation of the consensus. We analysed clinical characteristics, the rate of cardiac CTs and CAGs prior to KT as well as major adverse cardiac events (MACEs) during a 2-year follow-up after KT. RESULTS The three study groups showed a homogeneous distribution of comorbidities and age. Significantly more cardiac CTs (13.6% versus 10.2% versus 44.8%; P = 0.002) and CAGs (39.6% versus 43.9% versus 56.2%; P = 0.003) were performed after the consensus. Coronary interventions were performed during 42 out of 260 CAGs (16.2%), the cumulative 2-year MACE incidence was 8.7%. Regarding MACE occurrence, no significant difference between the three groups was found. CONCLUSION CV risk stratification has become more rigorous and invasive after the implementation of the consensus; however, this was not associated with an improvement in CV outcome.

Abstract
PURPOSE OF REVIEW The kidney transplantation landscape has changed dramatically over the last 2 decades. First, transplantation is performed in patients previously considered ineligible for transplantation, including older patients and patients with multiple comorbidities. Second, organ shortages have increased the use of less-than-optimal donor kidneys, like organs from expanded criteria donors or donors after cardiac death. Third, improvements in managing chronic kidney disease and dialysis have improved survival on dialysis. Therefore, the question arises: does transplantation currently benefit older transplant candidates? RECENT FINDINGS The current review describes important changes in transplantation over the last 20 years. We review recent data on survival with dialysis versus transplantation in older individuals. Finally, we consider methodological issues that might influence conclusions drawn in current studies. SUMMARY Limited data are available to assess the potential survival benefit of kidney transplantations in older individuals. The available evidence suggests that transplantation might provide survival benefit in older individuals, even with aged kidney donors, but risks vary widely with donor quality and recipient health status. More research is needed to make adequate predictions of which donor kidneys might lead to good outcomes and which patient characteristics might define a good transplant candidate.

Abstract
BACKGROUND In the United Kingdom, 1 in 3 patients on the National Kidney Transplant Waiting List (NKTWL) is suspended from the list at least once during their wait. The mortality of this large cohort of patients remains underreported and poorly described. METHODS We linked patient records from the UK transplant registry to mortality data from the Office of National Statistics and evaluated the impact of a clinically induced suspension event by estimating hazard ratios (HRs) that compared mortality and graft survival between those who had experienced a suspension event and those who had not. RESULTS Between January 1, 2000, and December 31, 2010, 16.7% (2221/13 322) of all patients registered on the NKTWL were suspended. Forty-eight percent (588/1225) of those who were suspended and who were never transplanted died, most often from cardiothoracic causes. A suspension event was associated with increased mortality from the time of listing (adjusted HR [aHR], 1.79; 1.64-1.95) and from the time of transplantation (aHR, 1.20; 1.06-1.37; P = 0.005). Graft survival was also poorer in those who had been suspended (aHR, 1.13; 1.01-1.28; P = 0.04). CONCLUSIONS Patients suspended on the NKTWL have a significantly higher rate of mortality both on the waiting list and following transplantation. Earlier prioritization of patients at risk of experiencing a suspension event may improve their outcomes.

Abstract
BACKGROUND Kidney transplant improves patients' survival and quality of life. Worldwide, concern about the equality of access to the renal transplant wait-list is increasing. In Iran, patients have the choice to be placed on either the living or deceased-donor transplant wait-list. METHODS This was a prospective study performed on 416 kidney transplant recipients (n = 217 (52.2%) from living donors and n = 199 (47.8%) from deceased donors). Subjects were recruited from four referral kidney transplant centers across Tehran, Iran, during 2016-2017. The primary outcome was to identify the psycho-socioeconomic factors influencing the selection of type of donor (living versus deceased). Secondary objective was to compare the outcomes associated with each type of transplant. The impact of psycho-socioeconomic variables on selecting type of donor was evaluated by using multiple logistic regression and the effect of surgical and non-surgical variables on the early post-transplant creatinine trend was assessed by univariate repeated measure ANOVA. RESULTS Based on standardized coefficients, the main predictors for selecting living donor were academic educational level (adjusted OR = 3.25, 95% CI: 1.176-9.005, p = 0.023), psychological status based on general health questionnaire (GHQ) (adjusted OR = 2.46, 95% CI: 1.105-5.489, p = 0.028), and lower monthly income (adjusted OR = 2.20, 95% CI: 1.242-3.916, p = 0.007). The waiting time was substantially shorter in patients who received kidneys from living donors (p < 0.001). The early post-transplant creatinine trend was more desirable in recipients of living donors (β = 0.80, 95% CI: 0.16-1.44, p-value = 0.014), patients with an ICU stay of fewer than five days (β = - 0.583, 95% CI: - 0.643- -0.522, p-value = < 0.001), and those with less dialysis duration time (β = 0.016, 95% CI: 0.004-0.028, p-value = 0.012). Post-operative surgical outcomes were not different across the two groups of recipients (p = 0.08), however, medical complications occurred considerably less in the living-donor group (p = 0.04). CONCLUSION Kidney transplant from living donors was associated with shorter transplant wait-list period and better early outcome, however, inequality of access to living donors was observed. Patients with higher socioeconomic status and higher level of education and those suffering from anxiety and sleep disorders were significantly more likely to select living donors.

Abstract
Chronic kidney disease (CKD) affects over 10% of the global population and poses significant challenges for societies and health care systems worldwide. To illustrate these challenges and inform cost-effectiveness analyses, we undertook a comprehensive systematic scoping review that explored costs, health-related quality of life (HRQoL) and life expectancy (LE) amongst individuals with CKD. Costs were examined from a health system and societal perspective, and HRQoL was assessed from a societal and patient perspective. Papers published in English from 2015 onward found through a systematic search strategy formed the basis of the review. All costs were adjusted for inflation and expressed in US$ after correcting for purchasing power parity. From the health system perspective, progression from CKD stages 1-2 to CKD stages 3a-3b was associated with a 1.1-1.7 fold increase in per patient mean annual health care cost. The progression from CKD stage 3 to CKD stages 4-5 was associated with a 1.3-4.2 fold increase in costs, with the highest costs associated with end-stage renal disease at $20,110 to $100,593 per patient. Mean EuroQol-5D index scores ranged from 0.80 to 0.86 for CKD stages 1-3, and decreased to 0.73-0.79 for CKD stages 4-5. For treatment with renal replacement therapy, transplant recipients incurred lower costs and demonstrated higher HRQoL scores with longer LE compared to dialysis patients. The study has provided a comprehensive updated overview of the burden associated with different CKD stages and renal replacement therapy modalities across developed countries. These data will be useful for the assessment of new renal services/therapies in terms of cost-effectiveness.

Krzyżowska K, Kolonko A, Giza P, Chudek J, Więcek A. No Significant Influence of Reduced Initial Tacrolimus Dose on Risk of Underdosing and Early Graft Function in Older and Overweight Kidney Transplant Recipients. Transplant Proc 2018; 50:1755-1759. [PMID: 30056895 DOI: 10.1016/j.transproceed.2018.02.108] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2017] [Revised: 02/06/2018] [Accepted: 02/19/2018] [Indexed: 10/17/2022]
Abstract
BACKGROUND Nowadays, a reduced initial daily dose of tacrolimus (Tac) (0.1-0.15 mg/kg) is recommended for the majority of kidney transplant recipients (KTRs). The aim of the study was to analyze the safety of such a regimen, including the risk of first inadequately low Tac blood level, acute rejection (AR) occurrence, or early graft dysfunction. METHODS In 2011, we introduced a modified (0.1-0.15 mg/kg/d) initial Tac dosing regimen in older (>55 years) and/or overweight KTRs. To assure the safety of this protocol, we monitored the risk of inadequately low blood Tac level (<6 ng/mL) and incidence of AR or delayed graft function (DGF). The historical cohort with the higher Tac dosing regimen (0.2 mg/kg/d, n = 208) served as a control group. RESULTS The mean Tac daily dose in 78 KTRs (group with reduced dosing) was 0.133 (95% confidence interval [CI], 0.130-0.136) mg/kg and was significantly lower than the standard, previously prescribed dose of 0.195 (95% CI, 0.194-0.197) mg/kg. Of note, induction therapy was employed twice more often in the reduced Tac dosing group. The dose reduction resulted in a slight, nonsignificant decrease in first Tac trough level. The percentages of patients with first Tac troughs <6 ng/mL (5.1% vs 4.8%), AR (6.4% vs 5.8%), and DGF (25.6% vs 31.2%) were similar in the reduced and standard dosing groups. CONCLUSION The currently recommended reduction in Tac initial dosing does not increase the risk of inadequate immunosuppression and does not affect the early graft function. Regardless of Tac dose reduction, there is still a substantial risk of Tac overdosing in older or overweight KTRs.

Abstract
AIM to comparatively assess desensitization schemes with and without plasmapheresis in patients with low presensitization. SUBJECTS AND METHODS The investigators studied the efficiency of the two desensitization schemes (cascade plasma filtration + intravenous immunoglobulin used in a dose of 100 mg/kg in 19 patients (a study group; panel reactive antibodies (PRA) 25.1±6.1%) versus 2 g/kg in 23 patients (a comparison group, PRA 18.9±4.4%). The crossmatch reaction was negative in both groups. The median follow-up period was 23.5 (quartiles 1 and 3: 10.25 and 26) months. RESULTS The study group was noted to have 6 episodes of acute rejection and 1 episode of infection; the comparison group had 13 and 3 episodes, respectively. The overall renal graft survival was 79 and 65% in the study and comparison groups, respectively; the 1-year graft survival was 94 and 62%. Graft function was significantly better in the study group: there was a lower daily proteinuria level (p<0.001) at 3 months after transplantation; a higher glomerular filtration rate (GFR) (p=0.001) and a lower daily proteinuria level (p=0.01) at 6 months; a lower serum creatinine comcentration (p=0.001) and lower daily proteinuria (p=0.001) and a higher GFR (p=0.001) at one year. CONCLUSION Even with the relatively low level of sensitization, there is an increase in the frequency of acute rejection episodes and worse graft function. The efficiency of desensitization using cascade plasma filtration and low-dose intravenous immunoglobulin is higher than that with high-dose intravenous immunoglobulin.

Abstract
Translational research tries to apply findings from basic science to enhance human health and well-being. Many phases of the translational research may include non-medical tasks (information technology, engineering, nanotechnology, biochemistry, animal research, economy, sociology, psychology, politics, and so on). Using common bioethics principles to these areas might sometimes be not feasible, or even impossible. However, the whole process must respect some fundamental, moral principles. The purpose of this paper is to argument the need for a different approach to the morality in translational bioethics, and to suggest some directions that might be followed when constructing such a bioethics. We will show that a new approach is needed and present a few ethical issues that are specific to the translational research.

Abstract
The prevalence of end-stage renal disease is emerging as a serious worldwide public health problem because of the shortage of donor organs and the need to take lifelong immunosuppressive medication in patients who receive a transplanted kidney. Recently, tissue bioengineering of decellularization and recellularization scaffolds has emerged as a novel strategy for organ regeneration, and we review the critical technologies supporting these methods. We present a summary of factors associated with experimental protocols that may shed light on the future development of kidney bioengineering and we discuss the cell sources and bioreactor techniques applied to the recellularization process. Finally, we review some artificial renal engineering technologies and their future prospects, such as kidney on a chip and the application of three-dimensional and four-dimensional printing in kidney tissue engineering.

Abstract
Patients on waiting lists for kidney transplantation have higher mortality rates and have specific anxieties about their eligibility, process, and outcomes of wait-listing. We aimed to describe patient experiences and attitudes to wait-listing for kidney transplantation. Electronic databases were searched to September 2014. Thematic synthesis was used to analyze the findings. From 22 studies (n = 795 patients), we identified six themes: accepting the only option (chance to regain normality, avoiding guilt, impulsive decision-making); maintaining hope (determined optimism, appreciating a fortuitous gift, enduring for optimal outcomes, trust in clinical judgment); burden of testing (strenuous commitment, losing the battle, medical mistrust); permeating vulnerability (eligibility enigma, being threatened, angst of timing uncertainty, desperate urgency, living in limbo, spiraling doubt and disappointment, residual ambivalence); deprived of opportunity (unfairly dismissed, unexpected disqualification, self-resignation and acceptance, jealousy, suspicious of inequity); and moral guilt (awaiting someone's death, questioning deservingness). The waiting list offered hope of restored normality. However, the demands of workup, uncertainty about eligibility, and waiting times that exceeded expectations impelled patients to disillusionment, despair, and suspicion of inequity. Managing patient expectations and ensuring transparency of wait-listing and allocation decisions may allay patient disappointment and skepticism, to improve patient satisfaction and treatment outcomes.

Outcomes following renal transplantation in older people: a retrospective cohort study. BMC Geriatr 2013; 13:79.

Abstract
Background The mean age of renal transplant recipients is rising, with age no longer considered a contraindication. Outcomes in older patients have not, however, been fully defined. The aim of our study is to evaluate outcomes in older people following renal transplantation at a Scottish regional transplant unit. Methods All renal transplants from January 2001 to December 2010 were analysed (n = 762). Outcomes following renal transplantation in people over 65 years old were compared to those in younger patients. Outcome measures were: delayed graft function (DGF), primary non-function (PNF), biopsy proven acute rejection (BPAR), serum creatinine at 1 year and graft and recipient survival. Lengths of initial hospital stay and re-admission rates were also assessed. Student’s T-Test was used to analyse continuous variables, Pearson’s Chi-Squared test for categorical variables and the Kaplan-Meier estimator for survival analysis. Results Older recipients received proportionately more kidneys from older donors (27.1% vs. 6.3%; p < 0.001). Such kidneys were more likely to have DGF (40.7% vs. 16.9%; p < 0.001). Graft loss at 1 year was higher in kidneys from older donors (15.3% vs. 7.6%; p = 0.04). There was no significant difference in patient survival at 1 year based on the age of the donor kidney. Recipient age did not affect DGF (16.9% vs. 18.5%; p = 0.77) or graft loss at 1 year (11.9% vs. 7.8%; p = 0.28). Older recipients were, however, more likely to die in the first year post transplant (6.8% vs. 2.1%; p = 0.03). BPAR was less common in older patients (6.8% vs. 22%; p < 0.01). Older recipients were more likely to be readmitted to hospital (31.8% vs. 10.9%; p < 0.001). Conclusions Older patients experience good outcomes following renal transplantation and donor or recipient age alone should not preclude this treatment. An awareness of this in clinicians managing older patients is important since the prevalence of End Stage Renal Disease is increasing in this age group.

Abstract
Sociodemographic gradients have been widely reported in end-stage renal disease treatment, as in the general population. So should we be relieved by the report from Grace et al. of no such gradient in access to deceased donor kidney transplantation in Australia? Although the authors have adjusted for the 'competing risk' of living kidney donor transplantation, which is higher in higher socioeconomic groups, it feels a little early to be reassured.

Abstract
The concept of high-urgency (HU) renal transplantation was introduced in order to offer to patients, who are not able to undergo long-term dialysis treatment, a suitable renal graft in a short period of time, overcoming by this way the obstacle of the prolonged time spent on the waiting list. The goal of this study was to evaluate the patient and graft survivals after HU renal transplantation and compare them to the long-term outcomes of the non-high-urgency renal transplant recipients. The clinical course of 33 HU renal transplant recipients operated on at our center between 1995 and 2010 was retrospectively analyzed. The major indication for the HU renal transplantation was the imminent lack of access for either hemodialysis or peritoneal dialysis (67%). The patient survival of the study population was 67%, 56%, and 56%, whereas the graft survival was 47%, 35% and 35%, at 5, 10, and 15 years, respectively. In the comparison between our study population and the non-HU renal transplant recipients, our study population presented statistically significant (P < 0.05) lower patient survival rates. The HU renal transplant recipients also presented lower graft survival rates, but statistical significance (P < 0.05) was reached only in the 5-year graft survival rate.

Abstract
BACKGROUND The demand for kidney transplant exceeds organ supply; therefore, understanding patient-related and contextual factors associated with waiting list activation is key in ensuring that organ allocation is efficient and equitable. We sought to assess whether inequalities in wait-listing probability exist across centers and evaluate correlates of wait-listing in Italy. METHODS We linked the MigliorDialisi dataset (1,238 patients enrolled in 54 Italian hemodialysis centers) to administrative data concerning the activity of each participating center and contextual information abstracted from the Italian Institute of Statistics. We modeled the odds of waiting list activation for patients on dialysis by the subjects' sociodemographic, biomedical and psychosocial factors along with center-related and contextual factors. RESULTS The crude enlistment rate was 26% (95% CI 9-54) distributed as follows: 21, 34 and 33% in northern, central, and southern Italy, respectively (p < 0.01). Older patients with poorer health conditions and lower expectations toward transplantation outcomes were less likely to be wait-listed in multilevel multivariable logistic regression. In the fully adjusted model there was not a statistically significant variation in wait-listing across northern, central, and southern regions. However, the variance explained by center-related factors accounted for 12% (p < 0.01) of total variability in enlistment likelihood (20% in patients >65 years, p < 0.01). CONCLUSIONS Our results showed that inter-center variation exists after adjusting for case mix. Additionally, we identified individual modifiable factors associated with wait-listing inequalities.
