Maldonado AQ, Bradbrook K, Sjöholm K, Kjellman C, Lee J, Stewart D. The real unmet need: A multifactorial approach for identifying sensitized kidney candidates with low access to transplant. Clin Transplant 2023; 37:e14946. [PMID: 36841966 DOI: 10.1111/ctr.14946] [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: 07/29/2022] [Revised: 01/30/2023] [Accepted: 02/08/2023] [Indexed: 02/27/2023]
Abstract
BACKGROUND At the start of 2020, the kidney waiting list consisted of 2526 candidates with a calculated panel reactive antibody (CPRA) of 99.9% or greater, a cohort demonstrated in published research to have meaningfully lower than average access to transplantation even under the revised kidney allocation system (KAS). METHODS This was a retrospective analysis of US kidney registrations using data from the OPTN [Reference (https://optn.transplant.hrsa.gov/data/about-data/)]. The period-prevalent study cohort consisted of US kidney-alone registrations who waited at least 1 day between April 1, 2016, when HLA DQ-Alpha and DP-Beta unacceptable antigen data became available in OPTN data collection, to December 31, 2019. Poisson rate regression was used to model deceased donor kidney transplant rates per active year waiting and using an offset term to account for differential at-risk periods. Median time to transplant was estimated for each IRR group using the Kaplan-Meier method. Sensitivity analyses were included to address geographic variation in supply-to-demand ratios and differences in dialysis time or waiting time. RESULTS In this study, we found 1597 additional sensitized (CPRA 50-<99.9%) candidates with meaningfully lower than average access to transplant when simultaneously taking into account CPRA and other factors. In combination with CPRA, candidate blood type, Estimated Post-Transplant Survival Score (EPTS), and presence of other antibody specificities beyond those in the current, 5-locus CPRA were found to influence the likelihood of transplant. CONCLUSION In total, this suggests approximately 4100 sensitized candidates are on the waiting list who represent a community of disadvantaged patients who may benefit from progressive therapies and interventions to facilitate incompatible transplantation. Though associated with higher risks, such interventions may nevertheless be more attractive than remaining on dialysis with the associated accumulation of mortality risk over time.

Can J Kidney Health Dis 2021; 8:20543581211058932. [PMID: 34868609 PMCID: PMC8641119 DOI: 10.1177/20543581211058932] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Accepted: 09/23/2021] [Indexed: 11/22/2022] Open
Abstract
Background: Compatible pair participation in kidney paired donation (KPD) may increase the likelihood of finding suitable matches for all registered pairs. Retrospective studies have shown variable enthusiasm for participating in KPD in compatible pairs. Objective: The study objective was to gather potential living donor (PLD) and transplant candidate (TC) perspectives on compatible pair participation in KPD. Design: Surveys and qualitative interviews. Setting: Three transplant programs in Canada: Centre hospitalier de l’Université de Montréal in Montreal (Québec), Vancouver General Hospital, and St. Paul’s Hospital in Vancouver (British Columbia). Patients: Both PLDs and TCs undergoing evaluation for donation/transplantation between 2016 and 2018 at 3 transplant programs in Canada. Methods: Descriptive statistical analysis was performed for the results of the survey and thematic and content analysis method was used for the content of the qualitative interviews. Results: A total of 116 PLDs and 111 TCs completed surveys and an additional 18 PLDs and 17 TCs underwent semi-directed interviews. Of those surveyed, 61.2% of PLDs and 76.6% of TCs reported a willingness to participate in KPD as a compatible pair. The possibility of a more optimally matched kidney for the TC and policies ensuring prioritization of the TC for repeat transplantation in the event of early graft failure increased willingness to participate in KPD. Major concerns expressed during the interviews included the desire to retain the emotional bond of directed donation, the fear of chain breaks or donor reneging, delays in transplantation, and additional travel associated with participation in KPD. Limitation: The limitations of this study are that it was conducted in only 3 Canadian transplant programs and that the interviews and surveys were in French and in English. As a consequence, the results may not be reflective of the views of individuals not living in these 2 provinces and from ethnic minority populations. Conclusion: Most of the compatible PLDs and TCs surveyed were willing to participate in KPD. Ensuring timely transplantation and a more optimal match for TCs and offering a policy of reciprocity to ensure timely repeat transplantation for compatible recipients if their allograft fails post KPD transplant may further increase compatible pair participation in KPD.

Abstract
Individually tailoring education over time may help more patients, especially racial/ethnic minorities, get waitlisted and pursue deceased and living donor kidney transplant (DDKT and LDKT, respectively). We enrolled 802 patients pursuing transplant evaluation at the University of California, Los Angeles Transplant Program into a randomized education trial. We compared the effectiveness of Your Path to Transplant (YPT), an individually tailored coaching and education program delivered at 4 time points, with standard of care (SOC) education on improving readiness to pursue DDKT and LDKT, transplant knowledge, taking 15 small transplant-related actions, and pursuing transplant (waitlisting or LDKT rates) over 8 months. Survey outcomes were collected prior to evaluation and at 4 and 8 months. Time to waitlisting or LDKT was assessed with at least 18 months of follow-up. At 8 months, compared to SOC, the YPT group demonstrated increased LDKT readiness (47% vs 33%, P = .003) and transplant knowledge (effect size [ES] = 0.41, P < .001). Transplant pursuit was higher in the YPT group (hazard ratio: 1.44, 95% confidence interval: 1.15-1.79, P = .002). A focused, coordinated education effort can improve transplant-seeking behaviors and waitlisting rates. ClinicalTrials.gov registration: NCT02181114.

Abstract
Background Robotic assisted nephrectomy for living donation (RANLD) is a rapid emerging surgical technique competing for supremacy with totally laparoscopic and laparoscopic hand assisted techniques. Opinions about the safety of specific techniques of vascular closure in minimally invasive living kidney donation are heterogeneous and may be different for laparoscopic and robotic assisted surgical techniques. Methods We retrospectively analyzed perioperative and short-term outcomes of our first (n=40) RANLD performed with the da Vinci Si surgical platform. Vascular closure of renal vessels was performed by either double clipping or a combination of clips and non-transfixing suture ligatures. Results RANLD almost quintupled in our center for the observed time period. A total of n=21 (52.5%) left and n=19 (47.5%) right kidneys were procured. Renal vessel sealing with two locking clips was performed in 18 cases (45%) Both, clips and non-transfixing ligatures were used in 22 cases (55%). Mean donor age was 53.075±11.68 years (range, 28–70). The average total operative time was 150.75±27.30 min. Right donor nephrectomy (139±22 min) was performed significantly faster than left (160.95±27.93 min, P=0.01). Warm ischemia time was similar for both vascular sealing techniques and did not differ between left and right nephrectomies. No conversion was necessary. Clavien-Dindo Grade ≤IIIb complications occurred in (n=5) 12.5%. Grade IV and V complications did not develop. In particular no hemorrhage occurred using multiple locking clips or suture ligatures for renal vascular closure. Mortality was 0%. Thirteen kidneys (32.5%) were transplanted across the AB0 barrier. Conclusions RANLD is an emerging minimally invasive surgical technique which facilitates excellent perioperative and short-term outcomes also when using multiple locking clips or suture ligatures for renal vascular closure.

Abstract
We used data from the United Network for Organ Sharing registry of living kidney donors and recipients to identify correlates of paid employment among couples following spousal living donation. Among such couples, post-transplant employment of both spouses (41%) was as common as employment of the donor only (41%). However, when the recipient was female, donor-only employment after transplant was more than twice as likely as compared to employment of both spouses (relative risk ratio = 2.57; p < .001). We conclude that traditional gender roles regarding paid workforce participation may be associated with the likelihood of employment after spousal kidney donation.

Abstract
Incompatible living donor kidney transplantation (ILDKT) has been established as an effective option for end-stage renal disease patients with willing but HLA-incompatible living donors, reducing mortality and improving quality of life. Depending on antibody titer, ILDKT can require highly resource-intensive procedures, including intravenous immunoglobulin, plasma exchange, and/or cell-depleting antibody treatment, as well as protocol biopsies and donor-specific antibody testing. This study sought to compare the cost and Medicare reimbursement, exclusive of organ acquisition payment, for ILDKT (n = 926) with varying antibody titers to matched compatible transplants (n = 2762) performed between 2002 and 2011. Data were assembled from a national cohort study of ILDKT and a unique data set linking hospital cost accounting data and Medicare claims. ILDKT was more expensive than matched compatible transplantation, ranging from 20% higher adjusted costs for positive on Luminex assay but negative flow cytometric crossmatch, 26% higher for positive flow cytometric crossmatch but negative cytotoxic crossmatch, and 39% higher for positive cytotoxic crossmatch (p < 0.0001 for all). ILDKT was associated with longer median length of stay (12.9 vs. 7.8 days), higher Medicare payments ($91 330 vs. $63 782 p < 0.0001), and greater outlier payments. In conclusion, ILDKT increases the cost of and payments for kidney transplantation.

Abstract
In living donor transplantation, cold ischemia time is a concern in transplants involving kidney paired donation. The impact of cold ischemia time over eight hours is unknown. Here we examined the association of cold ischemia time with delayed graft function and allograft loss among 48,498 living recipients in the Scientific Registry of Transplant Recipients registry. The incidence of delayed graft function was low but significantly higher among patients with longer cold ischemia times (0-2.0 hours: 3.3%; 2.1-4.0 hours: 3.9%; 4.1-8.0 hours: 4.3%; 8.1-16.0 hours: 5.5%). In multivariate analyses, only those with cold ischemia times of 8.1-16.0 hours had increased odds of delayed graft function (odds ratio 1.47; 95% confidence interval 1.05-2.05) compared to patients with times of 0-2.0 hours. In multivariate time-to-event analyses, cold ischemia times of 16 hours or less were not associated with allograft loss from any cause including death or death-censored graft loss with hazard ratios for cold ischemia times between 8.0-16.0 hours of 0.97 (95% confidence interval 0.74-1.26) and 1.09 (0.81-1.48) compared to patients with times of 0-2.0 hours). The results were consistent in paired and non-kidney paired donation transplants and in those with living donors over 50 years of age. In subgroup analysis restricted to kidney paired donation recipients, there was no difference in the risk of delayed graft function with an odds ratio of 1.40 (0.88, 2.40) or all-cause graft loss with a hazard ratio of 0.89 (0.62, 1.30) in transplant recipients who received kidneys that were shipped versus not shipped. Thus, a cold ischemia time up to 16 hours has limited impact on living donor outcomes. These findings may help expand living donor transplantation through kidney paired donation.

Abstract
The combination of kidney paired donation (KPD) with desensitization represents a promising method of increasing the rate of living donor kidney transplantation (LDKT) in immunologically challenging patients. Patients who are difficult to match and desensitize due to strong donor specific antibody are may be transplanted by a combination of desensitization and KPD protocol with more immunologically favorable donor. We present our experience of combination of desensitization protocol with three-way KPD which contributed to successful LDKT in highly sensitized end stage renal disease patient. All recipients were discharged with normal and stable allograft function at 24 mo follow up. We believe that this is first report from India where three-way KPD exchange was performed with the combination of KPD and desensitization. The combination of desensitization protocol with KPD improves access and outcomes of LDKT.

Abstract
PURPOSE Outcome after living donor kidney transplantation is highly relevant, since recipient and donor were exposed to notable harm. Reliable identification of risk factors is necessary. METHODS Three hundred sixty-six living donor kidney transplants were included in this observational retrospective study. Relevant risk factors for renal impairment 1 year after transplantation and delayed graft function were identified with univariable and multivariable binary logistic regression and ordinal regression analysis. RESULTS Eighty-four patients (26.6 %) suffered from renal impairment KDIGO stage ≥4 1 year post-transplant; median estimated glomerular filtration rate was 35.3 ml/min. In multivariable ordinal regression, male recipient sex (p < 0.001), recipient body mass index (p = 0.006), donor age (p = 0.002) and high percentages of panel reactive antibodies (p = 0.021) were revealed as independent risk factors for higher KDIGO stages. After adjustment for post-transplant data, recipient male sex (p < 0.001), donor age (p = 0.026) and decreased early renal function at the first post-transplant outpatient visit (p < 0.001) were identified as independent risk factors. Delayed graft function was independently associated with long stay on the waiting list (p = 0.011), high donor body mass index (p = 0.043), prolonged warm ischemic time (p = 0.016) and the presence of preformed donor-specific antibodies (p = 0.043). CONCLUSIONS Broadening the donor pool with non-blood related donors seems to be legitimate, although with respect to careful medical selection, since donor age in combination with male recipient sex were shown to be risk factors for decreased graft function. Warm ischemic time and waiting time need to be kept as short as possible to avoid delayed graft function. Transplantation across HLA and ABO borders did not affect outcome significantly.

Abstract
BACKGROUND ABO-incompatible (ABOi) kidney transplantation is now an established form of renal replacement therapy, but the efficacy and safety of the different types of preconditioning therapies are unclear. We aimed to synthesize the totality of the published evidence about the effects of any form of preconditioning therapies in living donor ABOi kidney transplantation on graft and patient outcomes. METHODS We searched MEDLINE, Embase, and Clinicaltrial.gov databases (inception through June 2015) to identify all studies that described the outcomes of adult living donor ABOi kidney transplantations using any form of preconditioning therapies. Two independent reviewers identified studies, extracted data, and assessed the risk of bias. Data were summarized using the random effects model, and heterogeneity was explored using subgroup analyses. We assessed confidence in the evidence using the Grading of Recommendations Assessment, Development, and Evaluation framework. RESULTS Eighty-three studies (54 case reports and case series, 25 cohort, 2 case-control, and 2 registry studies) involving 4810 ABOi transplant recipients were identified. Overall, confidence in the available evidence was low. During a mean follow-up time of 28 (standard deviation [SD], 26.6) months, the overall graft survival for recipients who received immunoadsorption or apheresis was 94.1% (95% confidence interval [95%CI], 88.2%-97.1%) and 88.0% (95% CI, 82.6%-91.8%), respectively. For those who received rituximab or underwent splenectomy, the overall graft survival was 94.5% (95% CI, 91.6%-96.5%) and 79.7% (95% CI, 72.9%-85.1%), respectively. Data on other longer-term outcomes, including malignancy, were sparse. CONCLUSIONS Rituximab or immunoadsorption appeared to be promising preconditioning strategies before ABOi kidney transplantation. However, the overall quality of evidence and the confidence in the observed treatment effects are low. The increased use of ABOi kidney transplantation needs to be matched with randomized trials of different types, dosing, and frequency of preconditioning therapies so that this scarce resource can be used most effectively and efficiently.

Abstract
The development of a biotechnological platform for the removal of waste products (e.g. uremic toxins), often bound to proteins in plasma, is a prerequisite to improve current treatment modalities for patients suffering from end stage renal disease (ESRD). Here, we present a newly designed bioengineered renal tubule capable of active uremic toxin secretion through the concerted action of essential renal transporters, viz. organic anion transporter-1 (OAT1), breast cancer resistance protein (BCRP) and multidrug resistance protein-4 (MRP4). Three-dimensional cell monolayer formation of human conditionally immortalized proximal tubule epithelial cells (ciPTEC) on biofunctionalized hollow fibers with maintained barrier function was demonstrated. Using a tailor made flow system, the secretory clearance of human serum albumin-bound uremic toxins, indoxyl sulfate and kynurenic acid, as well as albumin reabsorption across the renal tubule was confirmed. These functional bioengineered renal tubules are promising entities in renal replacement therapies and regenerative medicine, as well as in drug development programs.

Abstract
A promising strategy for increasing living donor kidney transplant (LDKT) rates is improving education about living donation for both prospective kidney transplant recipients and living donors to help overcome the proven knowledge, psychological, and socioeconomic barriers to LDKT. A recent Consensus Conference on Best Practices in Live Kidney Donation recommended that comprehensive LDKT education be made available to patients at all stages of chronic kidney disease (CKD). However, in considering how to implement this recommendation across different healthcare learning environments, the current lack of available guidance regarding how to design, deliver, and measure the efficacy of LDKT education programs is notable. In the current article, we provide an overview of how one behavior change theory, the Transtheoretical Model of Behavior Change, can guide the delivery of LDKT education for patients at various stages of CKD and readiness for LDKT. We also discuss the importance of creating educational programs for both potential kidney transplant recipients and living donors, and identify key priorities for educational research to reduce racial disparities in LDKT and increase LDKT rates.

Abstract
The education, evaluation, and support of living donors before, during, and after donation have historically been considered the roles and responsibilities of transplant programs. Although intended to protect donors, ensure true informed consent, and prevent coercion, this structure often leaves referring nephrologists unclear about the donor process and uncertain regarding the ultimate outcome of potential donors for their patients. The aim of this article is to help the referring nephrologist understand the donor referral and evaluation process, help the referring nephrologist understand the responsibilities of the transplant program, and offer suggestions about how the referring nephrologist can help to improve efficiencies in the process of donor education and evaluation. A partnership between referring nephrologists and transplant programs is an important step in advancing living kidney donation. The referring nephrologists are the frontline providers and are in a unique position to offer education about living donation and improve efficiencies in the process. Understanding the donor referral and evaluation process, the responsibilities of the transplant program, and the potential role referring nephrologists can play in the process is critical to establishing such a partnership.

Abstract
BACKGROUND Kidney recipients in the O blood group are at a disadvantage in kidney exchange programs (KEPs) because they can only receive an organ from O blood group donors. A way to remedy this unfair situation is through altruistic unbalanced paired kidney exchange (AUPKE) where a compatible pair (CP) consisting of an O donor and a non-O recipient is invited to participate in a KEP. There is no established AUPKE program in Canada. The aim of this study was to gather transplant professionals' views on the conditions necessary for the implementation of an AUPKE program. METHODS Nineteen Canadian transplant professionals took part in semistructured interviews. The content of these interviews was analyzed using a qualitative data analysis method. RESULTS Respondents' recommendations focused on the following: (i) the logistics of AUPKE (e.g., not delaying the transplantation for the CP, retrieving organs locally, providing a good quality organ to the CP, and maintaining anonymity); (ii) the transplantation teams (e.g., establishing a consensus among members and ensuring sufficient resources); (iii) information provided to CPs; and (iv) research (e.g., looking into all transplant options for O recipients, studying all potential impacts of KEPs and AUPKE). CONCLUSION The respondents in our study made the following recommendations for the implementation of an AUPKE program: (i) CPs should not be disadvantaged, (ii) measures should be taken to ensure that all transplant team members agree to participate and that there are sufficient resources for implementation, (iii) comprehensive information should be provided to the CP, and (iv) further research is needed on AUPKE.

Abstract
Promising renal replacement therapies include the development of a bioartificial kidney using functional human kidney cell models. In this study, human conditionally immortalized proximal tubular epithelial cell (ciPTEC) lines originating from kidney tissue (ciPTEC-T1 and ciPTEC-T2) were compared to ciPTEC previously isolated from urine (ciPTEC-U). Subclones of all ciPTEC isolates formed tight cell layers on Transwell inserts as determined by transepithelial resistance, inulin diffusion, E-cadherin expression and immunocytochemisty. Extracellular matrix genes collagen I and -IV α1 were highly present in both kidney tissue derived matured cell lines (p<0.001) compared to matured ciPTEC-U, whereas matured ciPTEC-U showed a more pronounced fibronectin I and laminin 5 gene expression (p<0.01 and p<0.05, respectively). Expression of the influx carrier Organic Cation Transporter 2 (OCT-2), and the efflux pumps P-glycoprotein (P-gp), Multidrug Resistance Protein 4 (MRP4) and Breast Cancer Resistance Protein (BCRP) were confirmed in the three cell lines using real-time PCR and Western blotting. The activities of OCT-2 and P-gp were sensitive to specific inhibition in all models (p<0.001). The highest activity of MRP4 and BCRP was demonstrated in ciPTEC-U (p<0.05). Finally, active albumin reabsorption was highest in ciPTEC-T2 (p<0.001), while Na(+)-dependent phosphate reabsorption was most abundant in ciPTEC-U (p<0.01). In conclusion, ciPTEC established from human urine or kidney tissue display comparable functional PTEC specific transporters and physiological characteristics, providing ideal human tools for bioartificial kidney development.

Abstract
Despite heightened international interest in performing living donor kidney paired donation (KPD) transplantation after the publication of a research protocol by Ross and colleagues in 1997, only a few hundred have been performed worldwide. The major obstacle is that many individuals in end-stage renal disease are of blood type O and can only receive an organ from a donor of blood type O, whereas blood type O donors are "universal donors" and will be able to donate directly with an intended recipient of any blood type unless there is a positive crossmatch. To overcome this, patients with compatible but non-HLA identical donors over 45 years of age should be approached for inclusion in KPD program especially O blood group donors. Inclusion of all these additional pairs into the algorithm greatly increases chances of possible matches for O blood group recipients. We report successful three-way KPD transplantation resulting in transplantation of O blood group patient using compatible O blood group donor from India. None of the patients had delayed graft function or rejection and all had stable graft function on discharge without any medical and surgical complications. We need to allocate O blood group kidneys from compatible donors to overcome the barrier of HLA, non-HLA antibodies and other donor related factors to improve transplant quality and long term outcomes. This will increase transplantation of O blood group patients.

Abstract
BACKGROUND Kidney paired donation (KPD) is a rapidly growing modality for facilitating living donor kidney transplantation (LDKTx) for patients who are incompatible with their healthy, willing and living donor. The impact of donor-recipient age difference on long and short-term graft and patient survivals in LDKTx is still uncertain. METHODS A total of 1502 LDKTx recipients who received regular follow-up in our center from 1999 to 2012 were studied. Donor-recipient age difference was divided into subgroups (donor-recipient 0-10, 11-20, 0-20, 21-30, 31-40, and 21-40 years). Outcome measures included death censored graft, patient survival and acute rejection rate. RESULTS The 1-, 5-, 10-year patient survival of the donor-recipient age difference ≤20 years group showed no difference compared with the age difference >20 years group (94.5%, 83.2%, 71.9% and 95.2%, 86%, 77.8%, p = 0.053). The 1-, 5-, 10-year graft survival of the donor-recipient age difference ≤20 years group showed no difference compared with the age difference >20 years group (94.6%, 81.6%, 72.1% and 94%, 80%, 72.2%, p = 0.989). The rejection were also similar (17.5% vs. 16.5%, p > 0.05). There was no statistically significant difference in graft survival and acute rejection rate in all subgroups. CONCLUSIONS Older donors (usually within families) are not associated with worse outcome is reassuring. KPD should not be prohibited due to high donor-recipient age difference, when size of donor pool is small as in single center KPD program.

Abstract
Living donor kidney transplantation is the preferred treatment for patients suffering from end-stage renal disease. To alleviate the shortage of kidney donors, many advances have been made to improve the utilization of living donors deemed incompatible with their intended recipient. The most prominent of these advances is kidney paired donation (KPD), which matches incompatible patient-donor pairs to facilitate a kidney exchange. This review discusses the various approaches to matching and allocation in KPD. In particular, it focuses on the underlying principles of matching and allocation approaches, the combination of KPD with other strategies such as ABO incompatible transplantation, the organization of KPD, and important future challenges. As the transplant community strives to balance quantity and equity of transplants to achieve the best possible outcomes, determining the right long-term allocation strategy becomes increasingly important. In this light, challenges include making full use of the various modalities that are now available through integrated and optimized matching software, encouragement of transplant centers to fully participate, improving transplant rates by focusing on the expected long-run number of transplants, and selecting uniform allocation criteria to facilitate international pools.

Abstract
PURPOSE OF REVIEW Although living donor transplantation is considered an ethically acceptable undertaking for the purpose of saving another's life, its safety remains under investigation. RECENT FINDINGS Although living donors undertake considerable medical risks for no direct medical benefit, the question remains whether the risks are acceptable and should be tolerated by providers and patients or whether additional interventions and safeguards are needed to reduce and/or prevent complications. By reviewing complication risk statistics and synthesizing empirical research regarding risk-taking thresholds and attitudes, this paper examines the possibilities for determining an acceptable level of complication risk for living donors. This paper also delineates the ethical tensions surrounding protecting donors from unnecessary risk versus respecting donor autonomy to accept risks, and concludes by discussing the importance of donor follow-up and the value of donor registries. SUMMARY In the absence of information on long-term donor outcomes, transplant centers should take special precautions to protect prospective donors given increasing pressures to reduce the organ shortage and concerns that donors often disregard risks to themselves to save the lives of others.

Abstract
BACKGROUND Kidney Paired Donation (KPD) is a rapidly growing modality for facilitating living related donor kidney transplantation (LRDKTx) for patients who are incompatible with their healthy, willing, and living donors. Data scarcity on the outcome of KPD versus LRDKTx prompted us to review our experience. MATERIALS AND METHODS This was a single-center study of 224 patients on regular follow-up, who underwent LRDRTx from January 2010 to June 2012 at our institute. The aim of this study was to compare short-term graft survival, patient survival and rejection rates of KPD (group 1, n = 34) with those of LRDKTx (group 2, n = 190). All the recipients received triple immunosuppression and thymoglobulin induction in KPD group. Kaplan-Meier curves were used for survival analysis. In group 1, mean recipient age was 35.5 ± 13.2 years, 29 were men and mean donor age was 44.4 ± 8.17 years, 10 were men. In group 2, mean recipient age was 29.1 ± 10 years, 155 were men and mean donor age was 47.5 ± 9.69 years, 74 were men. Mean human leukocyte antigen (HLA) matching in group 1 and 2 was 1 versus 3.2 (p < 0.05). RESULTS One- and two-year patient survival showed no significant difference between the two groups (97.1%, 97.1% vs. 96.2%, 94.8%, respectively, p = 0.81). Death-censored graft survival also showed no significant difference between the two groups (97.1%, 97.1%, vs. 97.6%, 97.6%, p = 0.73). Acute rejection incidence was also similar (8.7% vs. 9.9%, p > 0.62). CONCLUSIONS Our study showed similar graft survival, patient survival and rejection rates of KPD versus LRDKTx over 2 years post-transplantation, encouraging the use of this approach for national KPD program.

Abstract
PURPOSE OF REVIEW Chronic renal allograft damage is one of the main problems after kidney transplantation. This review enumerates causes, describes available therapeutic options, and discusses options of the future. RECENT FINDINGS Alloantigen-dependent and alloantigen-independent factors are responsible for allograft damage. Prevention of renal allograft damage starts with interventions that occur surrounding the explantation in cadaveric organs. These include the use of dopamine or machine perfusion systems.Followed by the critical phase of ischemia/reperfusion injury, the LCN2/lipocalin-2, HAVCR1, and p38 MAPK pathway are new players involved in that process. Innate immunity plays a part, too. Cold ischemia time is associated with genes of apoptosis. Nondonor-specific antibodies like antihuman leukocyte antibodies-Ia or angiotensin type 1 receptor may also play a role. Recent research indicates that genetic polymorphism like the Ficolin-2 Ala258Ser polymorphism and the mannose-binding lectin-2 polymorphism are involved in that process. New therapeutic options are rare and in the future. However, there is some evidence that drugs interfering with metalloproteinases, sexual hormones like dihydroandrosterone, and mesenchymal stem cell therapy may be of importance. SUMMARY Taken together, although the understanding of chronic rejection has improved, the available therapeutic options remain scarce.

Outcome of kidney paired donation transplantation to increase donor pool and to prevent commercial transplantation: a single-center experience from a developing country. Int Urol Nephrol 2012; 45:1171-8. [PMID: 23136032 DOI: 10.1007/s11255-012-0323-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2012] [Accepted: 10/24/2012] [Indexed: 02/08/2023]
Abstract
BACKGROUND Economic constraints in operating an effective maintenance dialysis program leaves renal transplantation as the only viable option for end-stage renal disease patients in India. Kidney paired donation (KPD) is a rapidly growing modality for facilitating living donor (LD) transplantation for patients who are incompatible with their healthy, willing LD. MATERIALS AND METHODS The aim of our study was to report a single-center feasibilities and outcomes of KPD transplantation between 2000 and 2012. We performed KPD transplants in 70 recipients to avoid blood group incompatibility (n = 56) or to avoid a positive crossmatch (n = 14). RESULTS Over a mean follow-up of 2.72 ± 2.96 years, one-, five- and ten-year patient survival were 94.6, 81, 81 %, and death-censored graft survival was 96.4, 90.2, 90.2 %, respectively. Ten percent of patients were lost, mainly due to infections (n = 4). There was 14.2 % biopsy-proven acute rejection, and 5.7 % interstitial fibrosis with tubular atrophy eventually leading to graft loss. CONCLUSION The incidences of acute rejection, patient/graft survival rates were acceptable in our KPD program and, therefore, we believe it should be encouraged. These findings are valuable for encouraging participation of KPD pairs and transplant centers in national KPD program. It should be promoted in centers with low-deceased donor transplantation. Our study findings are relevant in the context of Indian government amending the Transplantation of Human Organs Act to encourage national KPD program. To our knowledge, it is largest single-center report from India.
