Several challenging obstacles remain to increasing the number of organ donations from deceased patients in a hospital setting. These include medical, administrative, and ethical issues. Possible medical obstacles include the failure of early recognition of possible donors and inadequate care of potential and actual donors. To maximize the use of donated organs, proper care of the donors and expedited donor consent cannot be overemphasized. The care rendered to patients should ensure appropriate perfusion and nutrition of the organs, with meticulous follow-up until organ recovery. For example, patients involved in accidents are presumed to be healthy, but many have no available medical history on file. At the time of organ recovery, unexpected infections or malignancies can be minimized by raising the index of suspicion of the presence of serious conditions in donors, especially in donors with unknown medical history. A careful physical examination and an appropriate and aggressive laboratory investigation may disclose the cause of suspected clinical conditions in these potential donors. Individuals who work in intensive care units are the main group of health care providers directly involved in the process of organ donation. Appointing a donor coordinator in each intensive care unit could improve all aspects of organ donation. Such coordination could harmonize efforts toward the goals mentioned above and surmount the obstacles encountered during deceased-donor organ donation. Here, we describe the preliminary results of the Proactive Detection Program, a collaboration between the Saudi Center for Organ Transplantation (the national organ donation and transplant supervising center) and intensive care units of donating hospitals. With its success in Saudi Arabia, it is hoped that it will be widely adopted in other regions.

To evaluate evidence of practice changes affecting kidney transplant program volumes, and donor, recipient and candidate selection in the era surrounding the introduction of Centers for Medicare and Medicaid Services (CMS) conditions of participation (CoPs) for organ transplant programs. Scientific Registry of Transplant Recipients; CMS ESRD and Medicare claims databases. Retrospective analysis of national registry data. A Cox proportional hazards model of 1-year graft survival was used to derive risks associated with deceased-donor kidney transplants performed from 2001 to 2010. Among programs with ongoing noncompliance with the CoPs, kidney transplant volumes declined by 38 percent (n = 766) from 2006 to 2011, including a 55 percent drop in expanded criteria donor transplants. Volume increased by 6 percent (n = 638) among programs remaining in compliance. Aggregate risk of 1-year graft failure increased over time due to increasing recipient age and obesity, and longer ESRD duration. Although trends in aggregate risk of 1-year kidney graft loss do not indicate that the introduction of the CoPs has systematically reduced opportunities for marginal candidates or that there has been a systematic shift away from utilization of higher risk deceased donor kidneys, total volume and expanded criteria donor utilization decreased overall among programs with ongoing noncompliance. © Health Research and Educational Trust.

Kidney transplantation from living donor is an established treatment in Spain since the 60s but has maintained a low level of activity until 2000, when the number of procedures and hospitals that perform this therapy experienced a gradual increase, reaching the highest figure in our history in 2009, with 235 living donor kidney transplants (which represents 10% of renal transplant activity). The reasons why living donor kidney transplantation is emerging in our country are diverse and can be focused in four main areas. 1) Better outcomes obtained when using living donors for kidney transplantation than those obtained with kidneys from deceased donors. Younger recipients with better HLA matching, the good health of the donor, the absence of any damages that occur in the kidney secondary to brain death, the small ischemic time and the possibility of preemptive transplantation can explain the best graft and patient survival. 2) The scarcity of sources: the relaxation of entry criteria on the waiting list implies an increasing challenge of the demand for transplant without the contribution of living donor kidney transplantation, especially in young recipients where the chances of obtaining an age-appropriate deceased donor are lower, due to the change in the profile of the deceased donor (increasingly older). 3) Improvement in the safety of the donor: the excellent evaluation and monitoring of donors (based on international standards) plus the use of less invasive surgical techniques are related to a low complication rate and to survival expectancies of living donors being similar to those of the general population. 4) Barriers overcome: The training effort by the transplant teams, hospital and regional coordinations, and the National Transplant Organization is giving excellent results, visible in the gradual increase in the number of hospitals with a program of living donor kidney transplantation and its activity. In addition, desensitization programs and the national cross-over kidney transplantation program have removed barriers to transplantation in cases of ABO incompatibility or positive crossmatch.

Kidneys from expanded criteria deceased donors may elicit a strong inflammatory response, predisposing recipients to an increased risk of cancer after transplantation. We aimed to determine the association between donor types and cancer risk after kidney transplantation. Using the Australian and New Zealand Dialysis and Transplant Registry, we assessed the association between different donor types (living donor, standard, and expanded criteria deceased donors) and the risk of cancer after kidney transplantation using adjusted Cox proportional hazard and competing risk models. Over a median follow-up period of 4.4 years in 7,040 patients (34,684 patient-years), 468 patients (6.6%) developed cancer. The overall risks for cancer were 1,080, 1,444, and 2,018 per 100,000 patient-years for recipients of living donor, standard, and expanded criteria deceased donor kidneys, respectively. Compared to recipients of living-donor kidneys, recipients of expanded criteria deceased donor kidneys were at an increased risk of cancer (adjusted hazard ratio [HR], 1.52; 95% confidence interval [95% CI], 1.15-2.02; P = 0.004), particularly for genitourinary cancer (adjusted HR, 1.79; 95% CI, 1.03-3.10; P = 0.038) and post-transplant lymphoproliferative disease (adjusted HR, 2.72; 95% CI, 1.38-5.37; P = 0.004). Recipients of expanded criteria deceased donor kidneys are at substantially increased risk of cancer, especially cancers with a viral etiology. Allocation of expanded criteria deceased donor kidneys to potential recipients should balance the harms, such as the excess risk of cancer against the survival gains and quality-of-life benefits associated with transplantation.

Historical data have suggested that donor smoking is associated with detrimental clinical outcomes for recipients of kidneys from deceased donors. However, the effects of smoking status of a kidney donor on the outcomes of the recipient in a contemporary setting of immunosuppression and transplant practice have not yet been ascertained. This retrospective, population-cohort study analyzed data of all deceased-donor kidney-alone transplant procedures performed in the United Kingdom between April 2001 and April 2013. Our study included 11?199 deceased-donor kidney allograft recipients, with median follow-up of 46 months posttransplant. In our cohort, 5280 deceased donors (47.1%) had a documented history of smoking. Deceased donors with versus those without smoking history were more likely to be younger (mean age of 48 vs 50 years; P < .001), be of white ethnicity (96.6% vs 95.3%; P < .001), and have brain death before donation (77.1% vs 74.9%; P = .006). On unadjusted survival analyses, overall patient survival was significantly shorter in patients who received kidney allografts from deceased donors with smoking history (hazard ratio of 1.12, 95% confidence interval, 1.00-1.25; P = .044). No significant association was seen for death-censored or overall graft survival. Our multivariate survival analyses showed that, after accounting for confounding factors, the effects of donor smoking status remained significant for patient survival (hazard ratio of 1.16, 95% CI, 1.03-1.29; P =.011) but not graft survival. This population-cohort study suggests that deceased-donor kidneys from smokers contribute to an increased risk of death for kidney allograft recipients. These study findings imply donor smoking history should be factored into the risk stratification decision for recipient selection to optimize decision making; however, further clarification and validation of these data are warranted.

While much of the discussion regarding expanding the donor pool for pediatric liver transplantation has surrounded the use of technical variant grafts, little attention has been directed toward changes in the deceased donor population. The aim of this study was to investigate trends in the circumstance of the death of deceased donors used for pediatric liver transplantation. All pediatric liver transplant recipients transplanted between 2002 and 2015 were identified in the UNOS database and were categorized based on the donor circumstance of death. There was no significant correlation between year of transplantation and number of pediatric liver transplants performed, pediatric donors, split livers, or living donors. There was a significant downward trend in donors from motor vehicle fatalities and an upward trend in suicide, non-MVA, and death due to natural causes. There was also an upward trend in drowning, one of the most common mechanisms of death among non-MVA in 2015. While the number of donors who died in MVA has fallen, the number of deceased donors who died from suicide, natural causes, and non-MVA, especially drowning, has increased, maintaining the overall number of pediatric deceased donor livers transplanted. © 2018 John Wiley & Sons A/S.

The key restriction of transplantation medicine globally, as well as in the Czech Republic, concerns the lack of organs. The number of deceased donors, and thus the availability of organ transplants, has been stagnating in our country. The paper describes current legal regulations governing the dia-gnosis of brain death and primary legal and medical criteria for the contraindication of the deceased for organ explantation, gives an overview of the number of liver transplants, age structure, and diagnosis resulting in brain death of the deceased liver donors in the Czech Republic.

Deceased organ donation for transplantation: Challenges and opportunities

Organ transplantation saves thousands of lives every year but the shortage of donors is a major limiting factor to increase transplantation rates. To allow more patients to be transplanted before they die on the wait-list an increase in the number of donors is necessary. Patients with devastating irreversible brain injury, if medically suitable, are potential deceased donors and strategies are needed to successfully convert them into actual donors. Multiple steps in the process of deceased organ donation can be targeted to increase the number of organs suitable for transplant. In this review, after describing this process, we discuss current challenges and potential strategies to expand the pool of deceased donors. PMID:27683626

To review epidemiologic data's and medical results of deceased donation in renal transplantation. Relevant publications were identified through Medline (http://www.ncbi.nlm.nih.gov) and Embase (http://www.embase.com) database using the following keywords, alone or in association, "brain death; cardiac arrest; deceased donation; organ procurement; transplantation". Articles were selected according to methods, language of publication and relevance. The reference lists were used to identify additional historical studies of interest. Both prospective and retrospective series, in French and English, as well as review articles and recommendations were selected. In addition, French national transplant and health agencies (http://www.agence-biomedecine.fr and http://www.has-sante.fr) databases were screened using identical keywords. A total of 2498 articles, 8 official reports and 17 newspaper articles were identified; after careful selection 157 publications were eligible for our review. Deceased donation may involve either brain death or non-heartbeating donors (NHBD). Organ shortage led to the procurement of organs from expanded-criteria donors, with an increased age at donation and extended vascular disease, leading to inferior results after transplantation and underlining the need for careful donor management during brain death or cardiac arrest. Evolution of French legislation covering bioethics allowed procurement from Maastricht categories II and recently III non-heartbeating donors. The increase of organ shortage emphasizes the need for a rigorous surgical technique during procurement to avoid loss of transplants. A history or current neoplasm in deceased-donors, requires attention to increase the pool of organs without putting the recipients at risk for cancer transmission. French NHBD program, especially from Maastricht category III, may stand for a potential source of valuable organs. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

Deceased organ donors, where the cause of death is meningitis or encephalitis, are a potential concern because of the risks of transmission of a potentially fatal infection to recipients. Using the UK Transplant Registry, a retrospective cohort analysis of deceased organ donors in the UK was undertaken to better understand the extent to which organs from deceased donors with meningitis and/or encephalitis (M/E) (of both known and unknown cause) have been used for transplantation, and to determine the associated recipient outcomes. Between 2003 and 2015, 258 deceased donors with M/E were identified and the causative agent was known in 188 (72.9%). These donors provided 899 solid organs for transplantation (455 kidneys and 444 other organs). The only recorded case of disease transmission was from a donor with encephalitis of unknown cause at time of transplantation who transmitted a fatal nematode infection to 2 kidney transplant recipients. A further 3 patients (2 liver and 1 heart recipient) died within 30 days of transplantation from a neurological cause (cerebrovascular accident) with no suggestion of disease transmission. Overall, patient and graft survival in recipients of organs from donors with M/E were similar to those for all other types of deceased organ donor. Donors dying with M/E represent a valuable source of organs for transplantation. The risk of disease transmission is low but, where the causative agent is unknown, caution is required. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Transplantation rates for living- but not deceased-donor kidneys vary with socioeconomic status in Australia.

Socioeconomic disadvantage has been linked to reduced access to kidney transplantation. To understand and address potential barriers to transplantation, we used the Australia and New Zealand Dialysis and Transplant Registry and examined primary kidney-only transplantation among adult non-Indigenous patients who commenced chronic renal replacement therapy in Australia during 2000-2010. Socioeconomic status was derived from residential postcodes using standard indices. Among the 21,190 patients who commenced renal replacement therapy, 4105 received a kidney transplant (2058 from living donors (660 preemptive) or 2047 from deceased donors) by the end of 2010. Compared with the most socioeconomic disadvantaged quartile, patients from the most advantaged quartile were more likely to receive a preemptive transplant (relative rate 1.93), and more likely to receive a living-donor kidney (adjusted subhazard ratio 1.34) after commencing dialysis. Socioeconomic status was not associated with deceased-donor transplantation. Thus, the association between socioeconomic status and living- but not deceased-donor transplantation suggests that potential donors (rather than recipients) from disadvantaged areas may face barriers to donation. Although the deceased-donor organ allocation process appears essentially equitable, it differs between Australian states.

The presence of donor-specific anti-HLA antibodies (DSAs) is associated with increased risk of graft failure after kidney transplant. We hypothesized that DSAs against HLA class I, class II, or both classes indicate a different risk for graft loss between deceased and living donor transplant. In this study, we investigated the impact of pretransplant DSAs, by using single antigen bead assays, on long-term graft survival in 3237 deceased and 1487 living donor kidney transplants with a negative complement-dependent crossmatch. In living donor transplants, we found a limited effect on graft survival of DSAs against class I or II antigens after transplant. Class I and II DSAs combined resulted in decreased 10-year graft survival (84% to 75%). In contrast, after deceased donor transplant, patients with class I or class II DSAs had a 10-year graft survival of 59% and 60%, respectively, both significantly lower than the survival for patients without DSAs (76%). The combination of class I and II DSAs resulted in a 10-year survival of 54% in deceased donor transplants. In conclusion, class I and II DSAs are a clear risk factor for graft loss in deceased donor transplants, while in living donor transplants, class I and II DSAs seem to be associated with an increased risk for graft failure, but this could not be assessed due to their low prevalence. © 2018 The Authors.

Outcomes for transplants from living unrelated donors are of particular interest in kidney paired donation (KPD) programs where exchanges can be arranged between incompatible donor-recipient pairs or chains created from nondirected/altruistic donors. Using Scientific Registry of Transplant Recipients data, we analyzed 232,705 recipients of kidney-alone transplants from 1998 to 2012. Graft failure rates were estimated using Cox models for recipients of kidney transplants from living unrelated, living related, and deceased donors. Models were adjusted for year of transplant and donor and recipient characteristics, with particular attention to mismatches in age, sex, human leukocyte antigens (HLA), body size, and weight. The dependence of graft failure on increasing donor age was less pronounced for living-donor than for deceased-donor transplants. Male donor-to-male recipient transplants had lower graft failure, particularly better than female to male (5%-13% lower risk). HLA mismatch was important in all donor types. Obesity of both the recipient (8%-18% higher risk) and donor (5%-11% higher risk) was associated with higher graft loss, as were donor-recipient weight ratios of <75%, compared with transplants where both parties were of similar weight (9%-12% higher risk). These models are used to create a calculator of estimated graft survival for living donors. This calculator provides useful information to donors, candidates, and physicians of estimated outcomes and potentially in allowing candidates to choose among several living donors. It may also help inform candidates with compatible donors on the advisability of joining a KPD program. Copyright © 2017 by the American Society of Nephrology.

Public perception and misperceptions of socioeconomic disparities affect the willingness to donate organs. To improve our understanding of the flow of deceased donor kidneys, we analyzed socioeconomic status (SES) and racial/ethnic gradients between donors and recipients. In a retrospective cohort study, traditional demographic and socioeconomic factors, as well as an SES index, were compared in 56,697 deceased kidney donor and recipient pairs transplanted between 2007 and 2012. Kidneys were more likely to be transplanted in recipients of the same racial/ethnic group as the donor (p < 0.001). Kidneys tended to go to recipients of lower SES index (50.5% of the time, p < 0.001), a relationship that remained after adjusting for other available markers of donor organ quality and SES (p < 0.001). Deceased donor kidneys do not appear to be transplanted from donors of lower SES to recipients of higher SES; this information may be useful in counseling potential donors and their families regarding the distribution of their organ gifts. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Effective serological and molecular screening of deceased tissue donors.

A comprehensive and effective screening programme is essential to support the banking of tissues from deceased donors. However, the overall quality of the samples obtained from deceased donors, quantity and condition, is often not ideal, and this may lead to problems in achieving accurate and reliable results. Additionally a significant percentage of referrals are still rejected upon receipt as unsuitable for screening. We are actively involved in improving the overall quality of deceased donor screening outcomes, and have specifically evaluated and validated both serological and molecular assays for this purpose, as well as developing a specific screening strategy to minimise the specificity issues associated with serological screening. Here we review the nature and effectiveness of the deceased donor screening programme implemented by National Health Service Blood and Transplant (NHSBT), the organisation with overall responsibility for the supply of tissue products within England. Deceased donor screening data, serological and molecular, from August 2007 until May 2012 have been collated and analysed. Of 10,225 samples referred for serology screening, 5.5 % were reported as reactive; of 2,862 samples referred for molecular screening, 0.1 % were reported as reactive/inhibitory. Overall 20 % of the serological and 100 % of the molecular screen reactivity was confirmed as reflecting true infection. The use of a sequential serology screening algorithm has resulted in a marked reduction of tissues lost unnecessarily due to non-specific screen reactivity. The approach taken by NHSBT has resulted in the development of an effective and specific approach to the screening of deceased tissue donors.

Summary Background and objectives There exists gross disparity in national deceased donor kidney transplant availability and practice: waiting times exceed 6 years in some regions, but some patients receive kidneys before they require dialysis. This study aimed to quantify and characterize preemptive deceased donor kidney transplant recipients and compare their outcomes with patients transplanted shortly after dialysis initiation. Design, setting, participants, & measurements Using the Scientific Registry of Transplant Recipients database, first-time adult deceased donor kidney transplant recipients between 1995 and 2011 were classified as preemptive, early (on dialysis≤1 year), or late recipients. Random effects logistic regression and multivariate Cox proportional hazards regression were used to identify characteristics of preemptive deceased donor kidney transplant and evaluate survival in preemptive and early recipients, respectively. Results Preemptive recipients were 9.0% of the total recipient population. Patients with private insurance (adjusted odds ratio=3.15, 95% confidence interval=3.01–3.29, P<0.001), previous (nonkidney) transplant (adjusted odds ratio=1.94, 95% confidence interval=1.67–2.26, P<0.001), and zero-antigen mismatch (adjusted odds ratio=1.45, 95% confidence interval=1.37–1.54, P<0.001; Caucasians only) were more likely to receive preemptive deceased donor kidney transplant, even after accounting for center-level clustering. African Americans were less likely to receive preemptive deceased donor kidney transplant (adjusted odds ratio=0.44, 95% confidence interval=0.41–0.47, P<0.001). Overall, patients transplanted preemptively had similar survival compared with patients transplanted within 1 year after initiating dialysis (adjusted hazard ratio=1.06, 95% confidence interval=0.99–1.12, P=0.07). Conclusions Preemptive deceased donor kidney transplant occurs most often among Caucasians with private insurance, and survival is fairly similar to survival of recipients on dialysis for <1 year.

The use of extended criteria donors is an effective way of reducing the shortage of deceased donor organs. Evidence of significant liver trauma in a deceased donor usually rules out transplantation of the liver. The aim of this study was to evaluate the use and outcomes of donor livers with preprocurement trauma. Records of all 312 deceased donors with a history of trauma between January 1986 and September 2007 were reviewed. Donors with macroscopic liver injuries were identified, and data from recipient medical records were obtained. Data on declined donor offers were also evaluated. The median donor age was 20 (range, 10-57) years, and 9 of 15 (60%) were male. The liver injuries were predominantly lacerations (grades 1-5) and vascular injury. The right lobe was resected because of extensive damage in 3 cases. This resulted in 2 left lobes (back-table cut-down) and 1 left lateral segment allograft (in situ split). For the 15 recipients, the median age was 43 (3-69) years. Primary nonfunction was not seen. There was no difference in survival between whole and partial allografts. Three deaths occurred within 3 months post-transplantation. During the same period, 42 of 1405 donor offers (3%) were declined because of extensive liver trauma or major ongoing intra-abdominal hemorrhage. In conclusion, the use of donor livers with preexisting trauma leads to acceptable outcomes. Strategies to deal with trauma include resection of the right lobe if required. Use of deceased donor livers with injury is a safe way to expand the donor pool.

Limited data exist on the impact of living kidney donation on the donor-recipient relationship. Purpose of this study was to explore motivations to donate or accept a (living donor) kidney, whether expected relationship changes influence decision making and whether relationship changes are actually experienced. We conducted 6 focus groups in 47 of 114 invited individuals (41%), asking retrospectively about motivations and decision making around transplantation. We used qualitative and quantitative methods to analyze the focus group transcripts. Most deceased donor kidney recipients had a potential living donor available which they refused or did not want. They mostly waited for a deceased donor because of concern for the donor's health (75%). They more often expected negative relationship changes than living donor kidney recipients (75% vs. 27%, p = 0.01) who also expected positive changes. Living donor kidney recipients mostly accepted the kidney to improve their own quality of life (47%). Donors mostly donated a kidney because transplantation would make the recipient less dependent (25%). After transplantation both positive and negative relationship changes are experienced. Expected relationship changes and concerns about the donor's health lead some kidney patients to wait for a deceased donor, despite having a potential living donor available. Further research is needed to assess whether this concerns a selected group.

Many deceased liver donors with a history of alcohol abuse are excluded based upon medical history alone. This paper summarizes the transplant outcomes for a large number of deceased liver donors with a documented history of alcohol abuse. The records for 1478 consecutive deceased liver donors were reviewed (2001-2012). As per the United Network for Organ Sharing criteria, heavy alcohol use by an organ donor is defined as chronic intake of two or more drinks per day. Donors with a documented history of alcohol abuse were divided into three groups according to duration of abuse (<10 years, 10-24 years and 25 + years). Reperfusion biopsies are reported. Outcomes include biopsy appearance, early graft function and early and late graft survival. There were 161 donors with alcohol abuse: <10 years (29%); 10-24 years (42%); and ≥25 years (29%). Risk of 90-day graft loss for these three groups was: 0%, 3% and 2%, compared to 3% for all other donors (P = 0.62). Graft survival at 1 year for donor grafts with and without alcohol abuse was 89% and 87% (P = 0.52). There was no difference in early graft function. Cox proportional hazards modelling for graft survival demonstrates no statistically significant difference in survival up to 10 years post-transplant. This study demonstrates successful transplantation of a large number of deceased donor liver grafts from donors with a documented history of alcohol abuse (n = 161; 11% of all grafts). These extended criteria donor allografts may, therefore, be utilized successfully with similar outcomes. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The use of a ureteral stent can cause a urinary tract infection (UTI), although it reduces urologic complications. UTIs are associated with a higher rate of ureteral stent colonization (USC). The aim of this study was to compare USC in living and deceased donor renal transplant recipients. We conducted a prospective study of 48 patients who underwent renal transplantation between January and December 2016. The stents were removed aseptically, the inner surface of proximal and distal ends of stents were irrigated with liquid culture medium, and then they were vortexed for bacteriological investigation. Urine cultures were taken at the same time. A total of 45 renal transplantation patients (21 from cadavers, 24 from live donors) were evaluated in the study. The duration time of stent retention in patients with live donors was 25.04 ± 4.55 and in patients with deceased donors was 26.19 ± 4.08 days (P = .376). USC was observed in 12 (57.1%) and 6 (25%) patients while positive urine culture (PUC) was detected in 5 (23.8%) and 2 (8.3%) patients in deceased and live donor transplant recipients, respectively. Although the USC rate was significantly higher in the deceased donor renal transplant group (P = .022), there was no significant different in the rates of PUC (P = .137). Enterecoccus species was the common pathogen isolated from ureteral stent and urine. The micro-organisms isolated from ureteral stent in deceased and live donors, respectively, were distributed as follows: Enterococcus 5/3, Candida 3/1, Escherichia coli 2/1, Klebsiella pneumonia 1/1, and staphylococci in 1/0 patients. All E coli and K pneumoniae are extended spectrum beta-lactamase (ESBL)-positive isolates and resistant to sulfamethoxazole-trimethoprim (SMX/TMP). We report a high incidence of USC in deceased renal transplants. Enterecoccus instead of E coli is the most common pathogen during the first month after transplantation. Transplantation centers should be aware that deceased donor renal transplant recipients are more prone to stent-related infection and the antibacterial resistance rapidly increases in uropathogens.

There are more than 1.7 million sufferers of end stage kidney disease (ESKD) worldwide and for many a donated kidney provides the only chance of regaining independence from dialysis. Unfortunately, the demand for kidneys for transplantation far exceeds the available supply. It is important, therefore, that we understand the factors that may influence kidney donation rates. While certain socio-demographic factors have been linked to kidney donation rates, few studies have examined the influence of multiple socio-demographic factors on rates of both living and deceased kidney transplantation (KT) and none have examined their comparative effect in large numbers of culturally and socio-politically diverse countries. In this study, we performed univariate and multivariate analyses of the influence of 15 socio-economic factors on both the living donor (LD) and the deceased donor (DD) kidney transplantation rates (KTR) in 53 countries. Our analyses demonstrated that factors such as UN HDI (United Nations Human Development Index), religion, GDP, education, age, healthcare expenditure, presumed consent legislation and existence of a nationally managed organ donation program were associated with higher deceased KTR. In contrast, the only factors associated with living KTR were a highly significant negative association with presumed consent and variable associations with different religions. We suggest that by identifying factors that affect kidney transplantation rates these can be used to develop programs for enhancing donor rates in individual countries where those rates are below the leading countries. © 2013 The Authors.

Twenty years have passed since the 1997 enactment of the Organ Transplant Law in Japan, but the number of deceased donors remains extremely low. In this study we examine why deceased donation has continued to remain so infrequent. This investigation was a secondary analysis of published data from the Japan Organ Transplant Network, 2016 Fact Book of Organ Transplantation in Japan, and International Registry on Organ Donation and Transplantation. In the past 20 years, donation intent declarations, knowledge, and respect for family member's wishes have increased, whereas resistance toward transplantation has decreased. Despite this, the traditional perspective on corpses of gotai manzoku (ie, the soul cannot be put to rest without being physically intact and without defect), the family-centricism, and reward-seeking altruism have not changed much. Living organ transplants have alleviated the organ deficiency somewhat, and the law requiring family consent seems to have contributed to the observed small increase in deceased donors. The number of deceased donors is unlikely to increase suddenly. However, 8 strategies are proposed to increase the number of deceased donors, including: increasing the number of donor procurement coordinators and establishing a training system; increasing the number of organ procurement facilities; creating hub transplant centers and training transplant surgeons; implementing radical reform in public education; reducing workload and improving education of emergency physicians, neurosurgeons, and pediatricians; revisiting the stringent standards of brain-death determination; revisiting the registration process; and considering development of a Japanese version of organ procurement organizations as well as revisions to the Organ Transplant Law. The Japanese government and academic societies must work together to increase the number of deceased donors in Japan. Copyright © 2018 The Author(s). Published by Elsevier Inc. All rights reserved.

Maple syrup urine disease (MSUD) is an inherited disorder of branched chain ketoacid (BCKA) oxidation associated with episodic and chronic brain disease. Transplantation of liver from an unrelated deceased donor restores 9-13% whole-body BCKA oxidation capacity and stabilizes MSUD. Recent reports document encouraging short-term outcomes for MSUD patients who received a liver segment from mutation heterozygous living related donors (LRDT). To investigate effects of living related versus deceased unrelated grafts, we studied four Brazilian MSUD patients treated with LRDT who were followed for a mean 19 ± 12 postoperative months, and compared metabolic and clinical outcomes to 37 classical MSUD patients treated with deceased donor transplant. Patient and graft survival for LRDT were 100%. Three of 4 MSUD livers were successfully domino transplanted into non-MSUD subjects. Following LRDT, all subjects resumed a protein-unrestricted diet as mean plasma leucine decreased from 224 ± 306 μM to 143 ± 44 μM and allo-isoleucine decreased 91%. We observed no episodes of hyperleucinemia during 80 aggregate postoperative patient-months. Mean plasma leucine:isoleucine:valine concentration ratios were ~2:1:4 after deceased donor transplant compared to ~1:1:1.5 following LRDT, resulting in differences of predicted cerebral amino acid uptake. Mutant heterozygous liver segments effectively maintain steady-state BCAA and BCKA homeostasis on an unrestricted diet and during most catabolic states, but might have different metabolic effects than grafts from unrelated deceased donors. Neither living related nor deceased donor transplant affords complete protection from metabolic intoxication, but both strategies represent viable alternatives to nutritional management.

Utilization of Deceased Donor Kidneys to Initiate Living Donor Chains.

PubMed

2016-05-01

We propose that some deceased donor (DD) kidneys be allocated to initiate nonsimultaneous extended altruistic donor chains of living donor (LD) kidney transplants to address, in part, the huge disparity between patients on the DD kidney waitlist and available donors. The use of DD kidneys for this purpose would benefit waitlisted candidates in that most patients enrolled in kidney paired donation (KPD) systems are also waitlisted for a DD kidney transplant, and receiving a kidney through the mechanism of KPD will decrease pressure on the DD pool. In addition, a LD kidney usually provides survival potential equal or superior to that of DD kidneys. If KPD chains that are initiated by a DD can end in a donation of an LD kidney to a candidate on the DD waitlist, the quality of the kidney allocated to a waitlisted patient is likely to be improved. We hypothesize that a pilot program would show a positive impact on patients of all ethnicities and blood types. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

The donation rate (DR) per million population is not ideal for an efficiency comparison of national deceased organ donation programs. The DR does not account for variabilities in the potential for deceased donation which mainly depends on fatalities from causes leading to brain death. In this study, the donation activity was put into relation to the mortality from selected causes. Based on that metric, this study assesses the efficiency of different donation programs. This is a retrospective analysis of 2001-2015 deceased organ donation and mortality registry data. Included are 27 Council of Europe countries, as well as the USA. A donor conversion index (DCI) was calculated for assessing donation program efficiency over time and in international comparisons. According to the DCI and of the countries included in the study, Spain, France, and the USA had the most efficient donation programs in 2015. Even though mortality from the selected causes decreased in most countries during the study period, differences in international comparisons persist. This indicates that the potential for deceased organ donation and its conversion into actual donation is far from being similar internationally. Compared with the DR, the DCI takes into account the potential for deceased organ donation, and therefore is a more accurate metric of performance. National donation programs could optimize performance by identifying the areas where most potential is lost, and by implementing measures to tackle these issues.

Several events inspired us to collect data on organ transplantation in Poland (2016: the 50th anniversary of the first transplantation and the 20th anniversary of Polish Transplant Coordinating Center Poltransplant). The paper aims at presenting comprehensive data on all organ transplants, beginning with the first in 1966 (deceased kidney) until the end of 2014. Source documents were reports published in Poltransplant Bulletin, a website registry managed by Poltransplant, reports by the Transplantation Council and by the Transplantation Institute of Warsaw. A source data enabled us to establish a preliminary report, presented for verification during the 12th Congress of the Polish Transplantation Society. By the end of 2014, the total number of organ transplants was 26,691. Kidney transplantation is the most common (total number = 19,812). The number of living kidney transplants is low, about 50 per year. The number of liver part transplants from living donors is relatively high, 20 to 30 annually. The program of deceased liver transplantation results in more than 300 transplants yearly. The first heart transplantation was in 1985, but the number of these procedures has been decreasing. No significant increase in the number of lung transplantations was noted. The number of organ transplantations from deceased donors places Poland in the middle among European countries. The number of living donor kidney transplants is lower than in other countries; therefore a living donor liver transplantation program belongs to leading programs. Progress of lung transplantation has been slow. The development is highlighted by vascularized composite tissue transplantations of the hands and face. The strength of the report lies in its reliability and completeness. Numbers are the unique source of information to be used and referred to in the literature. Copyright © 2016 Elsevier Inc.

Use of kidneys from donors aged 70 years and older is controversial. Organ shortage has led many transplant centers to accept kidneys from old, suboptimal deceased donors and make increasing use of old-for-old allocation systems. We describe our institutional experience with outcomes from transplanting deceased-donor kidneys from older donors (=70 years). 20 deceased donor renal transplants (DDRTx) were performed at our center using grafts from deceased donors 70 years and older between June 2004 and September 2011. Kidneys were allocated to dual or single grafting according to pre-transplant biopsy. Mean age of recipients was 47.60 ± 11.38 years, 13 of whom were males. Mean donor age was 76.49 ± 4.9 years; 10 of whom were males. The most common cause of donor death was cerebrovascular/road traffic accidents. Mean dialysis duration pre-transplantation was 19.5 ± 6.5 months. Mean HLA (Human Leukocyte Antigens) match was 1 ± 0.8. Most common recipient diseases leading to ESRD were chronic glomerulonephritis (25%), diabetes (20%), and hypertension (20%). Post-transplant immunosuppression consisted of a calcineurin inhibitor-based regimen. Over a mean follow-up of 2.8 ± 1.7 years, patient and graft survival rates were 75% (n = 15) and 80% ( n = 16), respectively, with a mean serum creatinine of 1.78 ± 0.56 mg/dl; 20% of the patients had biopsy-proven acute rejection episodes. A total of 25% (n = 5) patients died, mainly due to infections. DDRTx from older donors achieves acceptable graft function with patient/graft survival, provided that organs are allocated to dual or single grafting according to pre-transplant biopsy. These findings encourage the use of this approach even in low-income countries.

The disproportion between the large organ demand and the low number of transplantations performed represents a serious public health problem worldwide. Reducing the loss of transplantable organs from deceased potential donors as a function of cardiac arrest (CA) may contribute to an increase in organ donations. Our purpose was to test the hypothesis that a goal-directed protocol to guide the management of deceased donors may reduce the losses of potential brain-dead donors (PBDDs) due to CA. The quality improvement project included 27 hospitals that reported deceased donors prospectively to the Transplant Center of the State of Santa Catarina, Brazil. All deceased donors reported prospectively between May 2012 and April 2014 were analyzed. Hospitals were encouraged to use the VIP approach checklist during the management of PBDDs. The checklist was composed of the following goals: protocol duration 12-24 hours, temperature > 35 °C, mean arterial pressure ≥ 65 mmHg, diuresis 1-4 ml/kg/h, corticosteroids, vasopressin, tidal volume 6-8 ml/kg, positive end-expiratory pressure 8-10 cmH 2 O, sodium < 150 mEq/L, and glycemia < 180 mg/dl. A logistic regression model was used to identify predictors of CA. There were 726 PBDD notifications, of which 324 (44.6) were actual donors, 141 (19.4 %) CAs, 226 (31.1 %) family refusals, and 35 (4.8 %) contraindications. Factors associated with CA reduction included use of the checklist (odds ratio (OR) 0.43, p < 0.001), maintenance performed inside the ICU (OR 0.49, p = 0.013), and vasopressin administration (OR 0.56, p = 0.04). More than three interventions had association with less CAs (OR 0.19, p < 0.001). After 24 months, CAs decreased from 27.3 % to 14.6 % (p = 0.002), reaching 12.1 % in the following two 4-month periods (p < 0.001). Simultaneous increases in organ recovered per donor and in actual donors were observed. A quality improvement program based on education and the use of a goal checklist for the management of potential donors inside the ICU is strongly associated with a decrease in donor losses and an increase in organs recovered per donor.

Qualification of serological infectious disease assays for the screening of samples from deceased tissue donors.

Whilst some of the assays used for serological screening of post-mortem blood samples from deceased tissue donors in some countries have been specifically validated by the manufacturer for this purpose, a significant number of those currently in use globally have not. Although specificity has previously been considered a problem in the screening of such samples, we believe that ensuring sensitivity is more important. The aim of this study was to validate a broader range of assays for the screening of post-mortem blood samples from deceased tissue donors. Six microplate immunoassays currently in use within National Health Service Blood and Transplant (NHSBT) for the screening of blood, tissue and stem cell donations were included. Representative samples from confirmed positive donors were titrated in screen negative post-mortem samples in parallel with normal pooled negative serum to determine if there was any inhibition with the post-mortem samples. There were no significant differences seen (P < 0.005) between the dilution curves obtained for the positive samples diluted in post-mortem samples and normal pooled sera. Although small numbers of samples were studied, it can be surmised that the post-mortem blood samples from deceased tissue donors, collected according to United Kingdom guidelines, are a suitable substrate for the assays evaluated. No diminution of reactivity was seen when dilution with sera from deceased donors was compared to dilution using pooled serum from live donors. In the absence of genuine low titre positive post-mortem samples, the use of samples spiked with various levels of target material provides a means of qualifying serological screening assays used by NHSBT for the screening of post-mortem blood samples from deceased tissue donors.

As the median age of deceased kidney donors rises, updated knowledge of transplant outcomes from older deceased donors in differing donor-recipient age groups is required. Using ERA-EDTA Registry data we determined survival outcomes of kidney allografts donated from the same older deceased donor (55-70 years), and transplanted into one recipient younger and one recipient of similar age to the donor. The recipient pairs were divided into two groups: group 1; younger (median age: 52 years) and older (60 years) and group 2; younger (41 years) and older (60 years). A total of 1410 adults were transplanted during 2000-2007. Compared to the older recipients, the mean number of functioning graft years at 10 years was 6 months longer in the group 1 and group 2 younger recipients (P < 0.001). Ten-year graft survival was 54% and 40% for the group 1 younger and older recipients, and 60% and 49% for the group 2 younger and older recipients. Paired Cox regression analyses showed a lower risk of graft failure (group 1 younger; adjusted relative risk [RRa]:0.57, 95% CI:0.41-0.79, and group 2 younger; RRa:0.63, 95% CI:0.47-0.85) in younger recipients. Outcomes from older deceased donor allografts transplanted into differing donor-recipient age groups are better than previously reported. These allografts remain a valuable transplant resource, particularly for similar-aged recipients. © 2017 Steunstichting ESOT.

Innovative deceased donor intervention strategies have the potential to increase the number and quality of transplantable organs. Yet there is confusion over regulatory and legal requirements, as well as ethical considerations. We surveyed transplant surgeons (n = 294), organ procurement organization (OPO) professionals (n = 83), and institutional review board (IRB) members (n = 317) and found wide variations in their perceptions about research classification, risk assessment for donors and organ transplant recipients, regulatory oversight requirements, and informed consent in the context of deceased donor intervention research. For instance, when presented with different research scenarios, IRB members were more likely than transplant surgeons and OPO professionals to feel that study review and oversight were necessary by the IRBs at the investigator, donor, and transplant center hospitals. Survey findings underscore the need to clarify ethical, legal, and regulatory requirements and their application to deceased donor intervention research to accelerate the pace of scientific discovery and facilitate more transplants. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

The suitable size of a graft is a key element in the success of liver transplantation. A small-for-size liver graft is very likely to sustain a significant degree of injury as a result of ischemia, preservation, reperfusion, and rejection. Usually, small-for-size grafts are a concern in living-donor liver transplantation rather than in deceased-donor liver transplantation. Here, we describe the successful transplantation of a liver from a 2-year-old deceased donor to a 61-year-old male recipient who suffered from liver failure related to hepatitis B. No report of successful deceased-donor liver transplantation with discrepancies between donor and recipient age and size to such an extent has been found in the literature. Despite unusually large discrepancies, with effort in minimizing the ischemic time, revised surgical techniques, and strong regenerative power of the "young" graft, the old patient's liver function gradually returned to normal. This again proves that the definition of a "suitable graft" evolves with time and experience. Copyright © 2012. Published by Elsevier Taiwan.

Maternal organ donation and acute injuries in surviving children.

The purpose of this study is to test whether maternal deceased organ donation is associated with rates of subsequent acute injuries among surviving children after their mother's death. This is a longitudinal cohort analysis of children linked to mothers who died of a catastrophic brain event in Ontario, Canada, between April 1988 and March 2012. Surviving children were distinguished by whether their mother was an organ donor after death. The primary outcome was an acute injury event in surviving children during the year after their mother's death. Surviving children (n=454) had a total of 293 injury events during the year after their mother's death, equivalent to an average of 65 events per 100 children per year and a significant difference comparing children of mothers who were organ donors to children of mothers who were not organ donors (21 vs 82, P<.001). This difference in subsequent injury rates between groups was equal to a 76% relative reduction in risk (95% confidence interval, 62%-85%). Deceased organ donation was associated with a reduction in excess acute injuries among surviving children after their mother's death. An awareness of this positive association provides some reassurance about deceased organ donation programs. Copyright © 2014 Elsevier Inc. All rights reserved.

In December of 2014, the Organ Procurement and Transplant Network implemented a new Kidney Allocation System (KAS) for deceased donor transplant, with increased priority for highly sensitized candidates (calculated panel-reactive antibody [cPRA] >99%). We used a modified version of the new KAS to address issues of access and equity for these candidates. In a simulation, 10,988 deceased donor kidneys transplanted into waitlisted recipients in 2010 were instead allocated to candidates with cPRA≥80% (n=18,004). Each candidate's unacceptable donor HLA antigens had been entered into the allocation system by the transplant center. In simulated match runs, kidneys were allocated sequentially to adult ABO identical or permissible candidates with cPRA 100%, 99%, 98%, etc. to 80%. Allocations were restricted to donor/recipient pairs with negative virtual crossmatches. The simulation indicated that 2111 of 10,988 kidneys (19.2%) would have been allocated to patients with cPRA 100% versus 74 of 10,988 (0.7%) that were actually transplanted. Of cPRA 100% candidates, 74% were predicted to be compatible with an average of six deceased donors; the remaining 26% seemed to be incompatible with every deceased donor organ that entered the system. Of kidneys actually allocated to cPRA 100% candidates in 2010, 66% (49 of 74) were six-antigen HLA matched/zero-antigen mismatched (HLA-A, -B, and -DR) with their recipients versus only 11% (237 of 2111) in the simulation. The simulation predicted that 10,356 of 14,433 (72%) candidates with cPRA 90%-100% could be allocated an organ compared with 7.3% who actually underwent transplant. Data in this simulation are consistent with early results of the new KAS; specifically, nearly 20% of deceased donor kidneys were (virtually) compatible with cPRA 100% candidates. Although most of these candidates were predicted to be compatible with multiple donors, approximately one-quarter are unlikely to receive a single offer.

Deceased Organ Donors and PHS Risk Identification: Impact on Organ Usage and Outcomes.

PubMed

Pruett, Timothy L; Clark, Marissa A; Taranto, Sarah E

2017-07-01

In 2013, the public health service (PHS) changed the criteria intended to identify organ donors that put the associated organ recipients at increased risk for acquiring human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV). The changing donor demographics, organ utilization, and outcomes associated with this change are not known. A review of the Organ Procurement and Transplantation Network database was performed to assess the impact of PHS donor designation on organ utilization and outcomes. After the 2013 modification, over 20% of all deceased organ donors in the United States were identified as PHS increased risk. Compared with the standard risk deceased organ donor, the PHS donor was younger, male, died from anoxia, more likely to be HCV and antibody reacting to hepatitis B core antigen+, and less likely to have diabetes or hypertension. Organs from the 18- to 34-year-old deceased donors with PHS risks (but relatively few medical comorbidities) and tested negative for HCV were less frequently transplanted compared with the standard risk donors (3.9 vs 4.2 organs transplanted per donor). However, the transplant patient and graft survival as well as risk of unexpected transmission of HIV, HBV, and HCV were equivalent, irrespective of PHS donor status. The rationale of using PHS donor designation that negatively impacts utilization of high-quality organs without the benefit of identifying the subset of organs with demonstrable proclivity to transmit HIV, HBV, or HCV needs to be reexamined.

Apolipoprotein L1 gene (APOL1) nephropathy variants in African American deceased kidney donors were associated with shorter renal allograft survival in a prior single-center report. APOL1 G1 and G2 variants were genotyped in newly accrued DNA samples from African American deceased donors of kidneys recovered and/or transplanted in Alabama and North Carolina. APOL1 genotypes and allograft outcomes in subsequent transplants from 55 U.S. centers were linked, adjusting for age, sex and race/ethnicity of recipients, HLA match, cold ischemia time, panel reactive antibody levels, and donor type. For 221 transplantations from kidneys recovered in Alabama, there was a statistical trend toward shorter allograft survival in recipients of two-APOL1-nephropathy-variant kidneys (hazard ratio [HR] 2.71; p = 0.06). For all 675 kidneys transplanted from donors at both centers, APOL1 genotype (HR 2.26; p = 0.001) and African American recipient race/ethnicity (HR 1.60; p = 0.03) were associated with allograft failure. Kidneys from African American deceased donors with two APOL1 nephropathy variants reproducibly associate with higher risk for allograft failure after transplantation. These findings warrant consideration of rapidly genotyping deceased African American kidney donors for APOL1 risk variants at organ recovery and incorporation of results into allocation and informed-consent processes. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

This study reports our experience using deceased donor liver grafts from HBsAg-positive donors. We performed eight cases of liver transplantation (LT) using grafts from deceased HBsAg-positive donors between November 2005 and October 2010. The median age of donors was 48 years (range: 26-64). HBV DNA in the serum of donors ranged from 44 to 395 IU/ml, but HBeAg in all donors was negative. Preoperative laboratory and liver biopsy samples revealed the absence of definitive cirrhotic features and hepatitis. All recipients showed HBsAg positive preoperatively except one patient with HBsAg(-) status post previous LT for HBV related liver cirrhosis. The median age was 60 years (range: 46-76) at LT. Post-LT antiviral management consisted of hepatitis B immunoglobulin and antiviral nucleos(t)ide analogues. The median follow-up period was 25.5 months (range: 14-82). Of eight recipients, two recipients experienced serum HBsAg and HBV DNA disappearance postoperatively. Three recipients died of HBV-unrelated causes. The remaining five recipients were stable with normal liver function and no marked pathologic changes on follow-up biopsies. This experience shows that LT using grafts from deceased HBsAg-positive donors is feasible, and may represent a valuable expansion of the pool of organ donors with appropriate antiviral management and monitoring. © 2013 Steunstichting ESOT.

Deceased kidney donors are increasingly "marginal," and many have risk factors for acute kidney injury (AKI) that may impact on subsequent renal transplant outcome. Despite this, determining the presence of AKI at the time of deceased organ donation remains difficult. Urine samples from 182 brainstem dead multi-organ donors (all of whom donated hearts that were transplanted) were analyzed for a Luminex(™) panel of biomarkers linked with AKI. This included KIM-1, NGAL, IFN-γ, TNF-α, cystatin C, Fractalkine and vascular endothelial growth factor. Levels were correlated to early renal transplant outcomes, most specifically delayed graft function. Donor urinary KIM-1 levels were significantly higher in donors whose kidneys displayed aberrant early function (p = 0.011). Fractalkine levels showed a trend toward elevation in such donors but uncorrected this did not attain significance. No correlation occurred with the remaining biomarkers. KIM-1 appears to show promise as a marker for AKI in deceased cardiac organ donors. The availability of a lateral flow device (Renastick(™) ) for KIM-1 that also demonstrates higher urinary KIM-1 levels in donors whose kidneys show aberrant initial function (p = 0.03), makes KIM-1 a potential indicator of AKI that may merit further evaluation for its application at the donor bedside. © 2014 John Wiley & Sons A/S.

Background Although increasing donor age adversely affects survival after liver transplantation, livers have been used from selected deceased donors older than 70 years. Although there are reports of excellent short-term results, long-term results are unknown. Our experience was reviewed with septuagenarian and octogenarian deceased donors to determine long-term outcomes. Methods All primary deceased donor liver transplants performed at our institution between July 1998 and December 2010 were reviewed. Recipients of livers procured after circulatory arrest, split and reduced-size livers and multiple organ transplants were excluded from the study. Patient and graft survival were calculated using the Kaplan–Meier method, and survival comparisons were made with the log-rank test. Results In total, 780 patients met inclusion criteria, and 109 patients received livers from donors older than 70 years (range = 70–86). There were no differences in long-term patient (P = 0.67) or graft (P = 0.42) survival between hepatitis C negative recipients of livers from older compared with younger donors. In contrast, 7-year survival for HCV-positive recipients of older donor livers was less than half that of HCV-negative recipients. Discussion Transplantation of livers from septua- and octogenarian donors can achieve excellent long-term patient and graft survival for selected HCV-negative patients. PMID:24467292

Identification of strategies to improve organ donor use remains imperative. Despite the association between hospital volume and outcomes for many common disease processes, there have been no studies that assess the impact of organ donor hospital volume on organ yield. A prospective observational study of all deceased organ donors managed by 10 organ procurement organizations across United Network for Organ Sharing regions 4, 5, and 6 was conducted from February 2012 to June 2015. To study the impact of hospital volume on organ yield, each donor was placed into a hospital-volume quartile based on the number of donors managed by their hospital. Stepwise logistic regression was used to identify the independent effect of hospital volume on the primary outcomes measure of having ≥4 organs transplanted per donor. Data from 4,427 donors across 384 hospitals were collected and hospitals were assigned quartiles based on their volume of deceased donors. Hospitals managed a mean ± SD of 3.3 ± 5.2 donors per hospital per year. After adjusting for age, ethnicity, donor type, blood type, BMI, creatinine, and organ procurement organization/donor service area, being managed in hospitals within the highest volume quartile remained a positive independent predictor of ≥4 organs transplanted per donor (odds ratio = 1.52; 95% CI 1.29 to 1.79; p < 0.001). Deceased organ donor hospital volume impacts organ yield, with the highest-volume centers being 52% more likely to achieve ≥4 organs transplanted per donor. Efforts should be made to share practices from these higher-volume centers and consideration should be given to centralization of donor care. Published by Elsevier Inc.

Kidney transplantation is now considered the treatment of choice for many human immunodeficiency virus (HIV)-infected patients with end-stage renal disease (ESRD). Graft survival rates using HIV-negative donors and carefully selected HIV-positive ESRD patients are similar to those observed in HIV-uninfected kidney transplant recipients. To address the relative shortfall in donated organs it has been proposed that organs from HIV-infected deceased donors might be allocated to HIV-infected patients on the transplant waiting list. Preliminary experience in South Africa reports promising short-term outcomes in a small number of HIV-infected recipients of kidney transplants from HIV-infected donors. We sought to replicate this experience in the UK by accepting kidney offers from HIV infected deceased donors for patients with HIV-infection on the kidney transplant waiting list. Here we report the UK's first cases of kidney transplantation between HIV-positive donors and recipients.

Assessment of deceased-donor organ quality is integral to transplant allocation practices, but tools to more precisely measure donor kidney injury and better predict outcomes are needed. In this study, we assessed associations between injury biomarkers in deceased-donor urine and the following outcomes: donor AKI (stage 2 or greater), recipient delayed graft function (defined as dialysis in first week post-transplant), and recipient 6-month eGFR. We measured urinary concentrations of microalbumin, neutrophil gelatinase–associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), IL-18, and liver-type fatty acid binding protein (L-FABP) from 1304 deceased donors at organ procurement, among whom 112 (9%) had AKI. Each biomarker strongly associated with AKI in adjusted analyses. Among 2441 kidney transplant recipients, 31% experienced delayed graft function, and mean±SD 6-month eGFR was 55.7±23.5 ml/min per 1.73 m2. In analyses adjusted for donor and recipient characteristics, higher donor urinary NGAL concentrations associated with recipient delayed graft function (highest versus lowest NGAL tertile relative risk, 1.21; 95% confidence interval, 1.02 to 1.43). Linear regression analyses of 6-month recipient renal function demonstrated that higher urinary NGAL and L-FABP concentrations associated with slightly lower 6-month eGFR only among recipients without delayed graft function. In summary, donor urine injury biomarkers strongly associate with donor AKI but provide limited value in predicting delayed graft function or early allograft function after transplant. PMID:26374609

Adult living donor liver transplantation has developed as a direct result of the critical shortage of deceased donors. Recent regulations passed by New York State require transplant programs to appoint an Independent Donor Advocacy Team to evaluate, educate, and consent to all potential living liver donors. Ethical issues surround the composition of the team, who appoints them, and the role the team plays in the process. Critics of living liver donation have questioned issues surrounding motivation and the ability of donors to provide true informed consent during a time of family crisis. This article will address issues surrounding the controversies and discuss how using the team can effectively evaluate and educate potential living liver donors and improve practice to ensure safety of living donors.

Are health professionals responsible for the shortage of organs from deceased donors in Malaysia?

The rate of organ donations from deceased donors in Malaysia is among the lowest in the world. This may be because of the passivity among health professionals in approaching families of potential donors. A questionnaire-based study was conducted amongst health professionals in two tertiary hospitals in Kuala Lumpur, Malaysia. Four hundred and sixty-two questionnaires were completed. 93.3% of health professionals acknowledged a need for organ transplantation in Malaysia. 47.8% were willing to donate their organs (with ethnic and religious differences). Factors which may be influencing the shortage of organs from deceased donors include: nonrecognition of brainstem death (38.5%), no knowledge on how to contact the Organ Transplant Coordinator (82.3%), and never approaching families of a potential donor (63.9%). There was a general attitude of passivity in approaching families of potential donors and activating transplant teams among many of the health professionals. A misunderstanding of brainstem death and its definition hinder identification of a potential donor. Continuing medical education and highlighting the role of the Organ Transplant Coordinator, as well as increasing awareness of the public through religion and the media were identified as essential in improving the rate of organ donations from deceased donors in Malaysia. © 2012 The Authors Transplant International © 2012 European Society for Organ Transplantation.

The Organ Procurement and Transplantation Network (OPTN) Deceased Donor Potential Study, funded by the Health Resources and Services Administration, characterized the current pool of potential deceased donors and estimated changes through 2020. The goal was to inform policy development and suggest practice changes designed to increase the number of donors and organ transplants. Donor estimates used filtering methodologies applied to datasets from the OPTN, the National Center for Health Statistics, and the Agency for Healthcare Research and Quality and used these estimates with the number of actual donors to estimate the potential donor pool through 2020. Projected growth of the donor pool was 0.5% per year through 2020. Potential donor estimates suggested unrealized donor potential across all demographic groups, with the most significant unrealized potential (70%) in the 50-75-year-old age group and potential Donation after Circulatory Death (DCD) donors. Actual transplants that may be realized from potential donors in these categories are constrained by confounding medical comorbidities not identified in administrative databases and by limiting utilization practices for organs from DCD donors. Policy, regulatory, and practice changes encouraging organ procurement and transplantation of a broader population of potential donors may be required to increase transplant numbers in the United States. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

Successful organ transplantation relies on several ancillary activities such as the identification of a compatible donor, organ allocation and procurement and the coordination of the transplant process. No existing study of the overall costs, in France, of these additional transplantation activities could be identified. This study determines the total additional costs of ancillary transplantation activities by comparing the costs of kidney transplantations with living donors against those using deceased donors. The data used are drawn from the 2013 public healthcare tariff calculations, PMSI recorded activity and transplant activity in 2012 as assessed and reported by the Agence de la biomédecine. The results show that, in 2012, additional transplant costs varied from 13835.44 € to 20050.67 € for a deceased donor and were 13601.66 € for a living donor. In conclusion, this study demonstrates that all the costs covered by National Health Insurance need to be taken into account in the economic impact evaluation of renal transplantation and during the development of this national priority activity.

Graft survival rates from deceased donors aged 35 years or less among all primary pediatric kidney transplant recipients in the United States between 1996 and 2004 were retrospectively examined to determine the effect of HLA-DR mismatches on graft survival. Zero HLA-DR-mismatched kidneys had statistically comparable 5-year graft survival (71%), to 1-DR-mismatched kidneys (69%) and 2-DR-mismatched kidneys (71%). When compared to donors less than 35 years of age, the relative rate of allograft failure was 1.32 (p = 0.0326) for donor age greater than or equal to age 35. There was no statistical increase in the odds of developing a panel-reactive antibody (PRA) greater than 30% at the time of second waitlisting, based upon the degree of HLA-A, -B or -DR mismatch of the first transplant, nor was there a 'dose effect' when more HLA antigens were mismatched between the donor and recipient. Therefore, pediatric transplant programs should utilize the recently implemented Organ Procurement and Transplantation Network's (OPTN)allocation policy, which prioritizes pediatric recipients to receive kidneys from deceased donors less than 35 years of age, and should not turn down such kidney offers to wait for a better HLA-DR-matched kidney.

This study explores the factors affecting the willingness of dialysis patients' family members to become involved in living and deceased organ donation. We utilize cross sectional data on 350 family members of dialysis patients collected through self-administered survey from June to October 2013. The factors affecting willingness to become deceased and living organ donors among respondents were identified by running logistic regressions. The findings reveal that ethnicity, education and role in family are significant factors explaining will­ingness for living donation, while ethnicity, knowledge of organ donation and donor age drive willingness for deceased donation. We also find that the reasons of respondents being unwilling to donate center on the lack of information and family objections for deceased donation, while being medically unfit, scared of surgery and family objections are the reasons for unwillingness to donate living organs. In light of our findings, educational efforts are suggested to decrease the reluctance to become in­volved in living and deceased donation.

The shortage of deceased-donor organs is compounded by donation metrics that fail to account for the total pool of possible donors, leading to ambiguous donor statistics. We sought to assess potential metrics of organ procurement organizations (OPOs) utilizing data from the Nationwide Inpatient Sample (NIS) from 2009-2012 and State Inpatient Databases (SIDs) from 2008-2014. A possible donor was defined as a ventilated inpatient death ≤75 years of age, without multi-organ system failure, sepsis, or cancer, whose cause of death was consistent with organ donation. These estimates were compared to patient-level data from chart review from two large OPOs. Among 2,907,658 inpatient deaths from 2009-2012, 96,028 (3.3%) were a "possible deceased-organ donor." The two proposed metrics of OPO performance were: (1) donation percentage (percentage of possible deceased-donors who become actual donors; range: 20.0-57.0%); and (2) organs transplanted per possible donor (range: 0.52-1.74). These metrics allow for comparisons of OPO performance and geographic-level donation rates, and identify areas in greatest need of interventions to improve donation rates. We demonstrate that administrative data can be used to identify possible deceased donors in the US and could be a data source for CMS to implement new OPO performance metrics in a standardized fashion. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

We report on the to date largest recovery of 11 organs from a single deceased donor with the transplantation of face, bilateral upper extremities, heart, 1 lung, liver (split for 2 recipients), kidneys, pancreas, and intestine. Although logistically challenging, this case demonstrates the feasibility and safety of the recovery of multiple thoracic and abdominal organs with multiple vascular composite allotransplants and tissues. Our experience of 8 additional successful multiple vascular composite allotransplants, thoracic, and abdominal organ recoveries suggests that such procedures are readily accomplishable from the same deceased donor.

Organ donation and transplant systems have unique characteristics based on the local culture and socioeconomic context. China's transplant and organ donation systems developed without regulatory oversight until 2006 when regulation and policy were developed and then implemented over the next several years. Most recently, the pilot project of establishing a voluntary citizen-based deceased donor program was established. The pilot program addressed the legal, financial, and cultural barriers to organ donation in China. The pilot program has evolved into a national program. Significantly, it established a uniquely Chinese donor classification system. The Chinese donor classification system recognizes donation after brain death (category I), donation after circulatory death (category II), and donation after brain death followed by circulatory death (category III). Through August 2014, the system has identified 2326 donors and provided 6416 organs that have been allocated though a transparent organ allocation system. The estimated number of donors in 2014 is 1147. As China's attitudes toward organ donation have matured and evolved and as China, as a nation, is taking its place on the world stage, it is recognizing that its past practice of using organs from executed prisoners is not sustainable. It is time to recognize that the efforts to regulate transplantation and provide voluntary citizen-based deceased organ donation have been successful and that China should use this system to provide organs for all transplants in every province and hospital in China. At the national organ transplant congress on October 30, 2014, the Chairman of the China's national organ donation and transplantation committee, Jeifu Huang required all hospitals to stop using organs from executed prisoners immediately and the civilian organ donation will be sole source for organ transplant in China starting January 2015. © 2015 American Association for the Study of Liver Diseases.

To determine the potential safety benefit of introducing nucleic acid testing (NAT) in tissue and organ donors, the risk of virus transmission was examined in a Canadian population. Anonymous data on Northern Alberta tissue and organ donors from 1998 to 2004 were used to determine the seroprevalence and estimate the seroincidence and residual risk of HIV, HBV, HCV and HTLV infection. Of the 3372 donors identified, 71.1% were surgical bone, 13.2% were living organ and 15.6% were deceased organ/tissue donors. Seroprevalence was: HIV 0.00%, HBV 0.09%, HCV 0.48% and HTLV 0.03%. Incidence (/100,000 p-yrs) and residual risks (/100,000 donors) could only be estimated for HBV (24.2 and 3.9) and HCV (11.2 and 2.2). Risk estimates were higher for deceased donors than surgical bone donors. HCV had the highest prevalence and HBV had the highest estimated incidence. HIV and HTLV risks were extremely low precluding accurate quantification. In this region of low overall viral prevalence, HCV NAT would be most effective in deceased organ donors. In surgical bone donors the cost of implementing NAT is high without significant added safety benefit.

Marginal kidney donor

Renal transplantation is the treatment of choice for a medically eligible patient with end stage renal disease. The number of renal transplants has increased rapidly over the last two decades. However, the demand for organs has increased even more. This disparity between the availability of organs and waitlisted patients for transplants has forced many transplant centers across the world to use marginal kidneys and donors. We performed a Medline search to establish the current status of marginal kidney donors in the world. Transplant programs using marginal deceased renal grafts is well established. The focus is now on efforts to improve their results. Utilization of non-heart-beating donors is still in a plateau phase and comprises a minor percentage of deceased donations. The main concern is primary non-function of the renal graft apart from legal and ethical issues. Transplants with living donors outnumbered cadaveric transplants at many centers in the last decade. There has been an increased use of marginal living kidney donors with some acceptable medical risks. Our primary concern is the safety of the living donor. There is not enough scientific data available to quantify the risks involved for such donation. The definition of marginal living donor is still not clear and there are no uniform recommendations. The decision must be tailored to each donor who in turn should be actively involved at all levels of the decision-making process. In the current circumstances, our responsibility is very crucial in making decisions for either accepting or rejecting a marginal living donor. PMID:19718332

More than 20 years ago living donor liver transplantation was introduced into clinical practice. Specifics of this method were developed initially for children and later on for adults particularly in regions where a liver transplantation program using deceased donors was not readily available. The most sensitive aspect of living donation, namely the danger to a healthy relative in order to perform the transplantation is immanent in the system and, thus, it is definitively a secondary option as compared to deceased organ donation. Following worldwide initial euphoria the numbers have markedly decreased in the western world since the start of the new millennium. In Asian countries in particular, much work has been done to optimize the procedure so that the donor safety and the outcome quality for the recipient have been impressively demonstrated in large patient populations. There is still a severe donor organ shortage and the option to allocate an optimal (partial) organ on an individual basis by living donation has given new impact to the discussion about a further rise in the profile of living donations here as well. The new version of the German transplantation legislation implemented in summer 2012 requires a number of conditions with respect to insurance for living donors. The current state and perspectives are presented here.

The year 2008 marked the 10th anniversary of the Japanese lung transplantation program started in accordance with the Japanese Organ Transplant Law, which took effect in 1997. A total of 105 lung transplantations, including 39 deceased-donor transplants and 66 living-related transplants, had been performed as of the end of 2007. This article is the 2008 official report of the Japanese Society of Lung and Heart-Lung Transplantation. It summarizes the data for clinical lung transplantation during the period 1998-2007 and discusses the current status of Japanese lung transplantation. The overall 5-year survival rate was 67.0%: including 53.4% and 74.6% for deceased-donor lung transplantation and living-donor lobar lung transplantation groups, respectively. The total operation-related and 1-month mortality rates after surgery were 3.8% and 10.4%, respectively. These data are better, or at least acceptable, in comparison with the international registry data.

Public awareness of organ donation fundamentally affects the organ transplantation programs. This study was performed to assess the attitude and willingness of high school adolescents regarding organ donation. The study population consisted of 416 high school girls who were studying in four grades of three educational courses. Data were collected by a questionnaire and included demographic variables and attitude and willingness, which were assessed based on the Likert scale. The SPSS v.16 was used for data analysis. The mean age of the study subjects was 16.26 ± 1.06 years, 31% studied in grade-1, 27% in grade-2 (25% natural sciences, 27% mathematics and 48% humanities), 26% in grade-3 (30% natural sciences, 34% mathematics and 36% humanities) and 16% in pre-university stage (32% natural sciences, 42% mathematics and 26% humanities). The students had a highly positive attitude toward organ donation (mean score 4.2 ± 0.54). The greatest willingness for organ donation was concerning the kidney (88%) and heart (84%), followed by the liver (83.4%), pancreas (79.6%), cornea (67.8%) and skin (51%). Willingness for deceased as well as living organ donation was indicated by 92% and 47%, respectively, of the participants. Organ donation was considered acceptable only to relatives by 5% of the participants when the donors were deceased donors and by 16% of the participants when the donors were living donors; donation to all needy persons from deceased donors was accepted by 87% of the participants and from living donors by 31%. The purpose of donation was stated as lending help to others by 89% and progression of science by 40.2% of the participants. Willingness for organ donation from a deceased relative was declared by 63% of the students. There was significant positive correlation between willingness for organ donation and attitude (P <0.001). In addition, attitude and willingness had positive correlation with educational levels, age and educational courses. Our study suggests that Iranian adolescents have a great attitude and willingness toward organ donation, which reflects favorable knowledge of transplantation. Further research on public awareness in both genders and various age ranges is needed.

Transplant-mediated alloimmune thrombocytopenia (TMAT) from donors with immune thrombocytopenia (ITP) can result in significant bleeding complications in the recipient. The risk to a recipient of TMAT if they receive an organ from a donor with ITP is unknown. The outcomes of recipients of organs from deceased donors with ITP recorded in the UK Transplant Registry between 2000 and 2015 were reviewed. Twenty-one deceased organ donors had a predonation diagnosis of ITP. These donors were significantly more likely to have died from intracranial hemorrhage than were all other deceased organ donors (85% vs. 57%, p < 0.001). Organs from donors with ITP resulted in 49 organ transplants (31 kidney, 14 liver, four heart), with only one case of TMAT, which occurred in a liver transplant recipient and resulted in death from bleeding complications 18 days posttransplantation. The recipient of a kidney from the same organ donor was not affected. Unadjusted 5-year patient and graft survival was significantly worse for liver transplant recipients from donors with ITP compared with liver transplant recipients from donors without ITP (64% vs. 85%, p = 0.012). Organs from donors with ITP may be considered for transplantation, but livers should be used with caution. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

The overall effectiveness of the NHSBT screening programme for infectious agents in deceased tissue donors is examined and evaluated in terms of current outcomes and how to improve upon these outcomes. The screening results and any subsequent confirmatory results from a total of 1659 samples from NHSBT deceased donors referred to NTMRL for screening for infectious agents were included in the analysis. Overall 1566/1659 (94.4%) of the samples were screen negative. A total of 93 were repeat reactive on screening for one or more of the mandatory markers screened for, of which only 12 (13%) were subsequently confirmed to be positive on confirmatory testing. The majority of the repeat reactive samples were demonstrating non-specific reactivity with the screening assays in use. Overall, the NHSBT screening programme for infectious agents in deceased tissue donors is very effective with a relatively low overall loss of donors because of non-specific reactivity. However, unnecessary loss of tissue products is not acceptable, and although this programme compares favourably with the outcomes of other such programmes, the confirmatory results obtained demonstrate both the need and the potential for improving the outcomes. This is particularly important as one donor may donate more than one product, and can be achieved very easily with a change to the screening algorithm followed, using the confirmatory data obtained to support and validate this change. CONTENTS SUMMARY: Critical analysis of the NHSBT screening programme for infectious agents in deceased tissue donors and a strategy involving the design and use of a different screening algorithm to improve these outcomes.

Increased cold ischemia time in cadaveric kidney transplants has been associated with a high rate of delayed graft function (DGF), and even with graft survival. Kidney transplantation using in-house donors reduces cold preservation time. The purpose of this study was to compare the clinical outcomes after transplantation in house and externally. We retrospectively reviewed the medical records of donors and recipients of 135 deceased-donor kidney transplantations performed in our center from March 2009 to March 2016. Among the 135 deceased donors, 88 (65.2%) received the kidneys from in-house donors. Median cold ischemia time of transplantation from in-house donors was shorter than for imported donors (180.00 vs 300.00 min; P < .001). The risks of DGF and slow graft function were increased among the imported versus in-house donors. Imported kidney was independently associated with greater odds of DGF in multivariate regression analysis (odds ratio, 4.165; P = .038). However, the renal function of recipients at 1, 3, 5, and 7 years after transplantation was not significantly different between the 2 groups. Transplantation with in-house donor kidneys was significantly associated with a decreased incidence of DGF, but long-term graft function and survival were similar compared with imported donor kidneys.

Kidney transplantation is the optimal therapy for end-stage renal disease, prolonging survival and reducing spending. Prior economic analyses of kidney transplantation, using Markov models, have generally assumed compatible, low-risk donors. The economic implications of transplantation with high Kidney Donor Profile Index (KDPI) deceased donors, ABO incompatible living donors, and HLA incompatible living donors have not been assessed. The costs of transplantation and dialysis were compared with the use of discrete event simulation over a 10-year period, with data from the United States Renal Data System, University HealthSystem Consortium, and literature review. Graft failure rates and expenditures were adjusted for donor characteristics. All transplantation options were associated with improved survival compared with dialysis (transplantation: 5.20-6.34 quality-adjusted life-years [QALYs] vs dialysis: 4.03 QALYs). Living donor and low-KDPI deceased donor transplantations were cost-saving compared with dialysis, while transplantations using high-KDPI deceased donor, ABO-incompatible or HLA-incompatible living donors were cost-effective (<$100 000 per QALY). Predicted costs per QALY range from $39 939 for HLA-compatible living donor transplantation to $80 486 for HLA-incompatible donors compared with $72 476 for dialysis. In conclusion, kidney transplantation is cost-effective across all donor types despite higher costs for marginal organs and innovative living donor practices. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

This research utilizes a laboratory experiment to evaluate the effectiveness of alternative public policies targeted at increasing the rate of deceased donor organ donation. The experiment includes treatments across different default choices and organ allocation rules inspired by the donor registration systems applied in different countries. Our results indicate that the opt-out with priority rule system generates the largest increase in organ donation relative to an opt-in only program. However, sizeable gains are achievable using either a priority rule or opt-out program separately, with the opt-out rule generating approximately 80% of the benefits achieved under a priority rule program.

Liver transplantation from deceased donors with a central nervous system (CNS) malignancy has some risk of tumor transmission to the recipient. Though the risk is small, this group of donors is regarded as marginal. The use of marginal grafts may be an acceptable alternative practice in order to expand the donor pool in countries where there is a shortage of donated organs. The aim of this study was to examine and present the outcomes of liver transplantations performed using donors with a CNS tumor. Between March 2002 and July 2017, 1990 (deceased donor: n=399, 20%; living donor: n=1591, 80%) liver transplantations were performed at the center. Of the 399 deceased donors, 17 (4.2%) had a CNS tumor. The data of donors with a CNS tumor and of recipients who survived for more than 1 month (n=11) were retrospectively reviewed. Demographic data, the grade of the CNS tumor, tumor transmission to recipient data, and survival rates were analyzed. Only 2 (18%) grafts were provided locally, 6 (54%) were offered to the transplantation center after all of the national centers had declined them, and 3 (37%) were made available to us by the national coordination center for patients with a documented notification of urgency. High-grade (grade III-IV) brain tumors were detected in 7 (64%) donors, while low-grade (grade I-II) tumors were found in 2 patients. The remaining 2 donors were not pathologically graded because the diagnosis was made radiologically. The 1-, 3-, and 5-year overall and tumor-free survival of the patients was estimated at 100%, 70%, and 45%, respectively. A median survival of 40 months (range: 13-62 months) was achieved in recipients of grafts from a donor with a CNS tumor and no donor-related malignant transformation was observed.

The aim of this study was to determine whether stratification of deceased donors by the United Network for Organ Sharing (UNOS) criteria negatively impacts graft survival. We retrospectively reviewed deceased donor and recipient pretransplant variables of kidney transplantations that occurred between February 1995 and December 2009. We compared clinical outcomes between standard criteria donors (SCDs) and expanded criteria donors (ECDs). The deceased donors consisted of 369 patients. A total of 494 transplant recipients were enrolled in this study. Mean age was 41.7±11.4 year (range 18-69) and 273 patients (55.4%) were male. Mean duration of follow-up was 8.8±4.9 years. The recipients from ECD kidneys were 63 patients (12.8%). The overall mean cold ischemia time was 5.7±3.2 hours. Estimated glomerular filtration rate at 1, 2, and 3 years after transplantation were significantly lower in ECD transplants (1 year, 62.2±17.6 vs. 51.0±16.4, p<0.001; 2 year, 62.2±17.6 vs. 51.0±16.4, p=0.001; 3 year, 60.9±23.5 vs. 54.1±18.7, p=0.047). In multivariate analysis, donor age (≥40 years) was an independent risk factor for graft failure. In Kaplan-Meier analyses, there was no significant difference in death-censored graft survival (Log rank test, p>0.05), although patient survival was lower in ECDs than SCDs (Log rank test, p=0.011). Our data demonstrate that stratification by the UNOS criteria does not predict graft survival. In order to expand the donor pool, new criteria for standard/expanded donors need to be modified by regional differences. © Copyright: Yonsei University College of Medicine 2017

Survival after liver transplantation is negatively impacted by use of elderly deceased donors, but excluding them would increase waiting times and waiting list mortality. We reviewed our experience with liver transplantation (LT) utilizing livers from deceased donors 65 yr of age and older to identify those factors that impact graft survival. All adult patients (≥ 18 yr old) who underwent primary LT using deceased donor livers from donors aged ≥ 65 yr between February 1995 and November 2003 were included. With multivariate analysis we found four unfavorable characteristics significantly associated with higher post-transplant graft failure rate. These characteristics are hepatitis C as an etiology of liver disease, Model for End-Stage Liver Disease score >20, serum glucose level of donor > 200 mg/dL at the time of liver recovery, and skin incision to aortic cross-clamp time > 40 minutes in the donor surgery. The five-yr estimated graft survival rates having 0, 1, 2, 3, and 4 unfavorable characteristics were 100%, 82.0%, 81.7%, 39.3%, and 25.0%, respectively (p < 0.05). Our data demonstrated good graft survival can be achieved in LT using elderly donor liver allografts with appropriate patient selection, donor blood glucose management and efficient liver recovery with minimal manipulation of the liver during donor surgery. © 2010 John Wiley & Sons A/S.

Context Donors showed poor glucose control in the period between declaration of brain death and organ recovery. The level of hyperglycemia in the donors was associated with a decline in terminal renal function. Objective To determine whether implementation of a quality improvement project improved glucose control and preserved renal function in deceased organ donors. Methods Data collected retrospectively included demographics, medical history, mechanism of death, laboratory values, and data from the United Network for Organ Sharing. Results After implementation of the quality improvement project, deceased donors had significantly lower mean glucose concentrations (mean [SD], 162 [44] vs 212 [42] mg/dL; P < .001) and prerecovery glucose concentration (143 [66] vs 241 [69] mg/dL; P < .001). When the donor cohorts from before and after the quality improvement project were analyzed together, mean glucose concentration remained a significant predictor of terminal creatinine level (P < .001). Multivariate analysis of delayed graft function in kidney recipients matched to donors indicated that higher terminal creatinine level was associated with delayed graft function in recipients (P < .001). Conclusion The quality improvement project improved donor glucose homeostasis, and the data confirm that poor glucose homeostasis is associated with worsening terminal renal function. PMID:26645930

Recent evidence suggests that HLA epitope-mismatching at HLA-DQ loci is associated with the development of anti-DQ donor-specific antibodies and adverse graft outcomes. However, the clinical significance of broad antigen HLA-DQ mismatching for graft outcomes is not well examined. Using the United Network Organ Sharing/the Organ Procurement and Transplantation Network (UNOS/OPTN) data, patients with primary kidney transplants performed between 2005 and 2014 were included. Patients were classified as having either zero HLA-DQ mismatches, or one or two HLA-DQ mismatches. Primary outcomes were death-censored graft survival and incidence of acute rejection. A total of 93,782 patients were included. Of these, 22,730 (24%) and 71,052 (76%) received zero and one or two HLA-DQ mismatched kidneys, respectively. After adjusting for variables including HLA-ABDR, HLA-DQ mismatching was associated with a higher risk of graft loss in living kidney donor recipients with an adjusted hazard ratio (HR) of 1.18 (95% confidence interval [95% CI], 1.07 to 1.30; P <0.01), but not in deceased kidney donor recipients (HR, 1.05; 95% CI, 0.98 to 1.12; P =0.18) ( P value for interaction <0.01). When taking cold ischemic time into account, HLA-DQ mismatching was associated with a higher risk of graft loss in deceased kidney donor recipients with cold ischemic time ≤17 hours (HR, 1.12; 95% CI, 1.02 to 1.27; P =0.002), but not in deceased kidney donor recipients with cold ischemic time >17 hours (HR, 0.97; 95% CI, 0.88 to 1.06; P =0.49) ( P value for interaction <0.01). Recipients with one or two HLA-DQ mismatched kidneys had a higher incidence of acute rejection at 1 year, with adjusted odds ratios of 1.13 (95% CI, 1.03 to 1.23; P <0.01) in deceased donor and 1.14 (95% CI, 1.03 to 1.27; P =0.02) in living donor kidney transplant recipients. Specific donor-DQ mismatches seemed to be associated with the risk of acute rejection and graft failure, whereas others did not. HLA-DQ mismatching is associated with lower graft survival independent of HLA-ABDR in living donor kidney transplants and deceased donor kidney transplants with cold ischemia time ≤17 hours, and a higher 1-year risk of acute rejection in living and deceased donor kidney transplants.

Liver transplantation in Turkey: historical review and future perspectives.

Since the first successful liver transplantation by Starzl et al. in 1967, liver transplantation has become the standard therapy for many liver diseases, mainly chronic liver disease. Most liver transplantations performed in Europe and North America utilize deceased donors while a considerable portion of organ requirements is supplied by living donors in Asian countries including Turkey. The actual history of solid organ transplantation in Turkey began with the pioneering work of Dr. Haberal in collaboration with Thomaz E. Starzl in 1974 in Colorado University at Denver. The first successful solid organ transplantation in Turkey was accomplished by Haberal in 1975 with a living donor renal transplantation. Subsequently, legislations no 2238 and 2594 dated 1979 and 1982, respectively, were passed, paving the way for cadaveric tissue/organ utilization and preservation in Turkey. The first deceased donor liver transplantation and the first living donor liver transplantation were performed in 1988 and 1990, respectively. There are currently 45 liver transplantation centers in Turkey. Of these, 25 are state universities, 8 are private (foundation) universities, 9 are private hospitals, and 3 are training and research hospitals belonging to the Ministry of Health. A total of 7152 liver transplantations were performed in Turkey between January 2002 and May 2014. Of these, 4848 (67.8%) used living donors and 2304 (32.2%) used deceased donors. These figures indicate that, despite widespread organ donation campaigns and media-sponsored propaganda, desired targets have not been met yet in providing deceased organ donation. Despite unsatisfactory levels attained in supplying deceased donors, both the number of annual liver transplantations and improvements in overall survival rates of organ transplanted patients continues to increase. Actually, the one-year patient survival rate after liver transplantation in 2013 was 80.5%. This rate is getting better with each passing year and believed to be close to 90% in the next few years.

This article is part of a study to gain insight into the decision-making process by looking at the views of the relatives of potential brain dead donors. Alongside a literature review, focus interviews were held with healthcare professionals about their role in the request and decision-making process when post-mortal donation is at stake. This article describes the perspectives of the relatives. A content-analysis of 22 semi-structured in-depth interviews with relatives involved in an organ donation decision. Three themes were identified: 'conditions', 'ethical considerations' and 'look back'. Conditions were: 'sense of urgency', 'incompetence to decide' and 'agreement between relatives'. Ethical considerations result in a dilemma for non-donor families: aiding people or protecting the deceased's body, especially when they do not know his/her preference. Donor families respect the deceased's last will, generally confirmed in the National Donor Register. Looking back, the majority of non-donor families resolved their dilemma by justifying their decision with external arguments (lack of time, information etc.). Some non-donor families would like to be supported during decision-making. The discrepancy between general willingness to donate and the actual refusal of a donation request can be explained by multiple factors, with a cumulative effect. Firstly, half of the participants (most non-donor families) stated that they felt that they were not competent to decide in such a crisis and they seem to struggle with utilitarian considerations against their wish to protect the body. Secondly, non-donor families refused telling that they did not know the deceased's wishes or contesting posthumous autonomy of the eligible. Thirdly, the findings emphasise the importance of Donor Registration, because it seems to prevent dilemmas in decision-making, at least for donor families. Discrepancies between willingness to consent to donate and refusal at the bedside can be attributed to an unresolved dilemma: aiding people or protect the body of the deceased. Non-donor families felt incompetent to decide. They refused consent for donation, since their deceased had not given any directive. When ethical considerations do not lead to an unambiguous answer, situational factors were pivotal. Relatives of unregistered eligible donors are more prone to unstable decisions. To overcome ambivalence, coaching during decision-making is worth investigation.

Should We Formulate an Incentivized Model Facilitating Kidney Donation from Living Donors? A Focus on Turkey's Current System.

Kidney transplantation is a lifesaving medical treatment. However, very high demand for kidneys with low kidney donation causes a black market that exploits patients' desperation and donors' vulnerability. The current kidney donation programs fail to produce promising results to avoid illegal and unethical kidney trafficking and commercialism. Even though the primary goal of kidney donation is to increase the number of deceased organ donations, in some countries, like Turkey, due to religious or cultural concerns, it is impossible to supply adequate deceased kidney donations. In this view, the aim of this paper is to examine kidney trafficking in the scope of Turkey's current organ donation system and propose a new model, named the Incentivized Kidney Donation Model (IKDM), to increase kidney donation from living donors. The model encompasses the following benefits offered to kidney donors; lifetime health insurance, exemptions from copayments/contribution shares, priority when receiving an organ, priority when finding a job, income tax exemptions for salaried employees, and free or discounted public utilities. This normative model has the potential to promote donors' altruistic acts as well as the solidarity and loyalty among members of a society without violating ethical values and internationally accepted principles. © 2018 John Wiley & Sons Ltd.

A2 to B Blood Type Incompatible Deceased Donor Kidney Transplantation in a Recipient Infected with the Human Immunodeficiency Virus: A Case Report.

Forbes, R C; DeMers, A; Concepcion, B P; Moore, D R; Schaefer, H M; Shaffer, D

With the introduction of the Kidney Allocation System in the United States in December 2014, transplant centers can list eligible B blood type recipients for A2 organ offers. There have been no prior reports of ABO incompatible A2 to B deceased donor kidney transplantation in human immunodeficiency virus-positive (HIV+) recipients to guide clinicians on enrolling or performing A2 to B transplantations in HIV+ candidates. We are the first to report a case of A2 to B deceased donor kidney transplantation in an HIV+ recipient with good intermediate-term results. We describe an HIV+ 39-year-old African American man with end-stage renal disease who underwent A2 to B blood type incompatible deceased donor kidney transplantation. Prior to transplantation, he had an undetectable HIV viral load. The patient was unsensitized, with his most recent anti-A titer data being 1:2 IgG and 1:32 IgG/IgM. Induction therapy of basiliximab and methylprednisolone was followed by a postoperative regimen of plasma exchange, intravenous immunoglobulin, and rituximab with maintenance on tacrolimus, mycophenolate mofetil, and prednisone. He had delayed graft function without rejection on allograft biopsy. Nadir serum creatinine was 2.0 mg/dL. He continued to have an undetectable viral load on the same antiretroviral therapy adjusted for renal function. To our knowledge, this is the first report of A2 to B deceased donor kidney transplantation in an HIV+ recipient with good intermediate-term results, suggesting that A2 donor kidneys may be considered for transplantation into HIV+ B-blood type wait list candidates.

Vital to patient safety is the accurate assessment and minimization of risk for human immunodeficiency virus (HIV), Hepatitis C (HCV), and Hepatitis B (HBV) virus transmission by deceased donor organ and tissue transplantation. The pathogens are tested by serological kits based on enzyme-linked immunosorbent assay (ELISA), chemiluminescence (CLIA) and eletrochemiluminescence (ECLIA) immunoassays. Organ transplantation is a highly successful life-saving treatment in Brazil, but the Brazilian Health Surveillance Agency currently mandates that all deceased organ donors are screened for HIV, HCV and HBV following living donor policies. In this review, six ELISA (Wama ® , Bio-Rad ® , Biomerieux ® , DiaSorin ® , Acon Biotech ® and Biokit ® ), three CLIA (Abbott ® , Siemens ® , Diasorin ® ) and one ECLIA (Roche ® ) were utilized for evaluating the effectiveness of those serological tests for deceased donors in Brazil according to manufacturer's guidelines. NAT for HIV, HCV and HBV can assist with detection of pre-seroconversion for those infections, and only Cobas ® TaqScreen MPX ® test, the Tigris System ® Procleix Ultrio Assay ® and the Bio-Manguinhos ® HIV/HCV/HBV NAT are commercially available. Between all the tests, only the manufacturer Abbott ® and Cobas ® TaqScreen MPX ® test are currently validated for cadaver samples.

To investigate potential beneficial effects of donor treatment with methylprednisolone on organ function and outcome after liver transplantation. It is proven experimentally and clinically that the brain death of the donor leads to increased levels of inflammatory cytokines and is followed by an intensified ischemia/reperfusion injury after organ transplantation. In experiments, donor treatment with steroids successfully diminished these effects and led to better organ function after transplantation. To investigate whether methylprednisolone treatment of the deceased donor is applicable to attenuate brain death-associated damage in clinical liver transplantation we conducted a prospective randomized treatment-versus-control study in 100 deceased donors. Donor treatment (n = 50) consisted of 250 mg methylprednisolone at the time of consent for organ donation and a subsequent infusion of 100 mg/h until recovery of organs. A liver biopsy was taken immediately after laparotomy and blood samples were obtained after brain death diagnosis and before organ recovery. Cytokines were assessed by real-time reverse transcriptase-polymerase chain reaction. Soluble serum cytokines were measured by cytometric bead array system. After methylprednisolone treatment, steroid plasma levels were significantly higher (P < 0.05), and a significant decrease in soluble interleukins, monocyte chemotactic protein-1, interleukin-2, interleukin-6, tumor necrosis factor-alpha, and inducible protein-10 was observed. Methylprednisolone treatment resulted in a significant downregulation of intercellular adhesion molecule-1, tumor necrosis factor-alpha, major histocompatibility complex class II, Fas-ligand, inducible protein-10, and CD68 intragraft mRNA expression. Significantly ameliorated ischemia/reperfusion injury in the posttransplant course was accompanied by a decreased incidence of acute rejection. Our present study verifies the protective effect of methylprednisolone treatment in deceased donor liver transplantation, suggesting it as a potential therapeutical approach.

Because of the serious organ shortage in Japan, the use of extended criteria (EC) donors is inevitable to increase the number of deceased donors. However, the influence of this practice on recipient outcomes has not been clarified yet. We analyzed donor and recipient factors to determine whether those factors, especially from EC donors impacted early recipient outcomes. From February 1999 to January 2011, 100 deceased liver transplantations were performed in Japan, including 85 consecutive adult cases (age≥18 years) who were studied to evaluate whether 6 recipient and 16 donor factors affected 3-month (90-day) recipient survival. Upon univariate analysis, Model for End-stage Liver Disease (MELD) score≥25 (P=.018), donor age≥55 years (P=.040), and cold ischemia time (CIT)≥10 hours (P=.00013) significantly reduced 3-month survival. Multivariate analysis confirmed the independent contributions of, three adverse factors including MELD score≥25 (P=.0133, odds ratio [OR]=12.3, 95% confidence interval [CI]=1.7-90.3), donor age≥55 years (P=.013, OR=14.0, 95% CI=1.6-119.5), and CIT≥10 hours (P=.0024, OR=67.6, 95% CI=4.5-1024.9). Three-month recipient survivals with 0, 1, 2, and 3 positive factors were 100% (n=34), 94.4% (n=36), 53.8% (n=13), and 0% (n=2), respectively (P<.0001). In conclusion, to improve recipient short-term survivals, minimizing CIT is the first priority. In the long-term, we must promote deceased donation to reduce recipient MELD scores by shortening the waiting time, and revise the allocation system to minimize CIT by giving priority to the local area.

Glazier, Alexandra K; Heffernan, Kate Gallin; Rodrigue, James R

2015-11-01

There are a number of regulatory barriers both perceived and real that have hampered widespread clinical research in the field of donation and transplantation. This article sets forth a framework clarifying the existing legal requirements and their application to the conduct of research on deceased donors and donor organs within the United States. Recommendations are focused on resolving some of the ambiguity surrounding deceased donor authorization for research, Health Insurance Portability and Accountability Act requirements and the role of institutional review board oversight. The successful conduct of clinical research in the field of donation and transplantation requires an understanding of these regulatory nuances as well as identification of important ethical principles to consider. Facilitation of these concepts will ultimately provide support for innovative research designed to increase the availability of organs for transplantation. Further work identifying the optimal infrastructure for overview of clinical research in the field should be given priority.

Renal allografts from deceased African Americans with two apolipoprotein L1 gene (APOL1) renal-risk variants fail sooner than kidneys from donors with fewer variants. Kidney Donor Risk Index (KDRI) was developed to evaluate organ offers by predicting allograft longevity and includes African American race as a risk factor. Substituting APOL1 genotype for race may refine the KDRI. For 622 deceased African American kidney donors, we applied 10-fold cross-validation approach to estimate contribution of APOL1 variants to a revised KDRI. Cross-validation was repeated 10,000 times to generate distribution of effect size associated with APOL1 genotype. Average effect size was used to derive the revised KDRI weighting. Mean current-KDRI score for all donors was 1.4930 versus mean revised-KDRI score 1.2518 for 529 donors with 0/1 variant and 1.8527 for 93 donors with 2 variants. Original and revised KDRIs had comparable survival prediction errors after transplantation, but the spread in Kidney Donor Profile Index based on presence/absence of 2 APOL1 variants was 37 percentage points. Replacing donor race with APOL1 genotype in KDRI better defines risk associated with kidneys transplanted from deceased African American donors, substantially improves KDRI score for 85-90% of kidneys offered, and enhances the link between donor quality and recipient need.

Existing methods to predict recipient allograft function during deceased-donor kidney procurement are imprecise. Understanding the potential renal reparative role for monocyte chemoattractant protein-1 (MCP-1), a cytokine involved in macrophage recruitment after injury, might help predict allograft outcomes. We conducted a sub-study of the multicenter prospective Deceased Donor Study cohort, which evaluated deceased kidney donors from five organ procurement organizations from May 2010 to December 2013. We measured urine MCP-1 (uMCP-1) concentrations from donor samples collected at nephrectomy to determine associations with donor acute kidney injury (AKI), recipient delayed graft function (DGF), 6-month estimated GFR (eGFR), and graft failure. We also assessed perfusate MCP-1 concentrations from pumped kidneys for associations with DGF and 6-month eGFR. AKI occurred in 111 (9%) donors. Median (interquartile range) uMCP-1 concentration was higher in donors with AKI compared to donors without AKI (1.35 [0.41-3.93] ng/ml vs. 0.32 [0.11-0.80] ng/ml, p<0.001). DGF occurred in 756 (31%) recipients, but uMCP-1 was not independently associated with DGF. Higher donor uMCP-1 concentrations were independently associated with higher 6-month eGFR in those without DGF [0.77 (0.10, 1.45) ml/min/1.73m 2 per doubling of uMCP1]. However, there were no independent associations between uMCP-1 and graft failure over a median follow-up of about 2 years. Lastly, perfusate MCP-1 concentrations significantly increased during pump perfusion but were not associated with DGF or 6-month eGFR. Donor uMCP-1 concentrations were modestly associated with higher recipient 6-month eGFR in those without DGF. However, the results suggest that donor uMCP-1 has minimal clinical utility given no associations with graft failure.

Regulated compensation for kidney donors in the Philippines.

The purpose of this review is to discuss the recent events and experiences in the Philippines related to compensated kidney donation. Between 2002 and 2008, the Philippine government, through the Department of Health, administered a program called the Philippine Organ Donation Program that allowed prospective kidney providers to sign up, be allocated to prospective recipients and receive gratuities for their kidney. Transplant tourism flourished during this period because of rampant disregard for the regulation limiting foreign recipients to 10% of total kidney transplants. There is evidence of inadequate donor care. Efforts to curb the problem included a ban on foreigners coming to the Philippines to have kidney transplants with Filipinos as donors as well as strengthening of the implementing rules and regulations of both the antihuman trafficking law and the organ donation law that allowed donation after brain death. The experience in the Philippines mirrored those in India and Pakistan where paid donors reported poor outcomes. An effective national kidney disease prevention program and the deceased donor program for transplantation should be aggressively promoted. Legislation against transplant commercialism is needed.

The first kidney transplant in Mexico was done on October 22, 1963 at the General Hospital of National Medical Center (CMN) of the Mexican Institute of Social Security. After the earthquake in 1985, the transplantation activity was continued at the Specialty Hospital of National Medical Center Century XXI. Our program has a continue activity for almost 48 years and a total of 2019 kidney transplants from October 1963 to December 2010. We describe our experience in 20 years. Retrospective cohort study that includes all kidney transplants performed in the period from January 1991 to December 2010. Descriptive statistics were used. The survival analysis was performed using the Kaplan Meier method. We show the patient survival, graft survival censored for death with functional graft and total graft survival (uncensored). We analyzed a total of 1544 kidney transplants. The percentage of living donor was 82.9 vs. deceased donor of 17.1%. Patient survival at 1, 5, 10, 15 and 20 years was 95.0, 91.8, 87.2, 81.1 and 70.1%, respectively; allograft survival rate censored for death with functional allograft at 1, 5, 10, 15 and 20 years was 93.0, 86.2, 76.2, 63.7 and 50.9%, respectively. Our Transplant center also take care of around 1300 living donors in the long term, looking for morbidities as risk factors for the unique kidney as metabolic syndrome, diabetes, hypertension and others. In our program, the main source of renal allografts was living donors. Our transplant center has to increase the organ procurement from deceased donors. An important contribution of our center has been the long follow up of living donors according to international consensus.

History of deceased organ donation, transplantation, and organ procurement organizations.

PubMed

Howard, Richard J; Cornell, Danielle L; Cochran, Larry

2012-03-01

The historical development of deceased organ donation, transplantation, and organ procurement organizations is reviewed. The concept of transplantation, taking parts from one animal or person and putting them into another animal or person, is ancient. The development of organ transplantation brought on the need for a source of organs. Although many early kidney transplants used kidneys from living donors, these donors could not satisfy the ever-growing need for organs, and extrarenal organs were recovered only from deceased donors. This need for organs to satisfy the great demand led to specialized organizations to identify deceased donors, manage them until recovery occurred, and to notify transplant centers that organs were available for their patients. The functions of these organ procurement organizations expanded to include other required functions such as education, accounting, and compliance with state and federal requirements. Because of the shortage of organs relative to the demand, lack of a unified organ allocation system, the perception that organs are a national resource and should be governed by national regulations, and to improve results of organ procurement organizations and transplant centers, the federal government has regulated virtually all phases of organ procurement and transplantation.

Organ donation rates have continued to fall seriously short of needs worldwide, with the lowest rates recorded among developing economies. This study seeks to analyze evidence from a developing economy to explore the usefulness of social psychological theory to solve the problem. The study deployed a large survey (n = 10 412) using a convenience sampling procedure targeted at increasing the number of Malaysians registered with the Ministry of Health, Malaysia who are willing to donate organs upon death. Structural equation modeling was deployed to estimate simultaneously the relative influence of cognitive and noncognitive variables on willingness to donate deceased organs. The cognitive factors of donation perception, socioeconomic status and financial incentives, and the noncognitive factors of demography and fear showed a high statistically significant (1%) relationship with willingness to donate organs after death. While financial incentives were significant, cash rewards showed the least impact. Donation perception showed the highest impact, which shows that the development of effective pedagogic programs with simultaneous improvements to the quality of services provided by medical personnel engaged in retrieving and transplanting deceased donor organs can help raise organ donation rates. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Children receive priority in the allocation of deceased donor kidneys for transplantation in the United States, but because allocation begins locally, geographic differences in population and organ supply may enable variation in pediatric access to transplantation. We assembled a cohort of 3764 individual listings for pediatric kidney transplantation in 2005-2010. For each donor service area, we assigned a category of short (<180 days), medium (181-270 days), or long (>270 days) median waiting time and calculated the ratio of pediatric-quality kidneys to pediatric candidates and the percentage of these kidneys locally diverted to adults. We used multivariable Cox regression analyses to examine the association between donor service area characteristics and time to deceased donor kidney transplantation. The Kaplan-Meier estimate of median waiting time to transplantation was 284 days (95% confidence interval, 263 to 300 days) and varied from 14 to 1313 days across donor service areas. Overall, 29% of pediatric-quality kidneys were locally diverted to adults. Compared with areas with short waiting times, areas with long waiting times had a lower ratio of pediatric-quality kidneys to candidates (3.1 versus 5.9; P<0.001) and more diversions to adults (31% versus 27%; P<0.001). In multivariable regression, a lower kidney to candidate ratio remained associated with longer waiting time (hazard ratio, 0.56 for areas with <2:1 versus reference areas with ≥5:1 kidneys/candidates; P<0.01). Large geographic variation in waiting time for pediatric deceased donor kidney transplantation exists and is highly associated with local supply and demand factors. Future organ allocation policy should address this geographic inequity.

Structural shortage of deceased donor kidneys for transplantation has resulted in the expansion of living donation programs. A number of possibilities are now being explored, since it became clear that donors do not need to be genetically related to their recipients. Apart from classical direct donation we now conduct paired exchange, list exchange, altruistic donation and domino paired exchange programs. Other alternative programs are desensitization and transplantation across the blood type barrier. The purpose of this article is to give a general view of all optimizing living donation programs by reviewing the literature. First we describe logistic solutions, thereafter the more intensive medical treatments. We observed a wide variation in clinical experiences with living donation dependent on local jurisdiction, culture and customs. Professionals disagree on various ethical issues inherent to alternative programs. In our opinion logistic solutions like paired exchange, list exchange and altruistic donation programs are to be preferred over the more medical demanding programs e.g. desensitization and transplantation across the blood type barrier.

Pancreas outcomes in pancreas after kidney transplantation (PAK) patients have been reported as being inferior to those of patients who receive simultaneous pancreas and kidney transplantation (SPK). The influence of the kidney donor (i.e. living versus deceased) has never been previously addressed. We retrospectively analysed all pancreas transplants performed in a single centre since 2007 and compared the outcomes between those patients who had previously received a living-donor kidney transplant (pancreas transplantation after living-donor kidney transplantation, PAldK; n = 18) or a deceased-donor kidney transplant (pancreas transplantation after deceased-donor kidney transplantation, PAddK; n = 28), using SPK (n = 139) recipients as a reference. Pancreas survival was similar between all groups, but inferior for PAldK when including only those with a functioning graft at day 90 post-transplantation (P = 0.004). Pancreas acute rejection was significantly increased in PAldK (67%; 1.8 ± 1.4 episodes/graft) when compared with PAddK (25%) and SPK (32%) (P < 0.05) patients. In a multivariate Cox regression model including known risk factors for pancreas rejection, PAldK was the only predictor of acute rejection (hazard ratio 6.82, 95% confidence interval 1.51-30.70, P < 0.05). No association was found between donor-recipient HLA mismatches and graft rejection. Repeated HLA mismatches between kidney and pancreas donors (0 versus 1-6) did not correlate with pancreas graft rejection or survival in either PAK transplantation group (P > 0.05). Pancreas graft outcomes are worse for PAldK when compared with PAddK and SPK patients.

BACKGROUND Due to the shortage of organs for transplantation, there has been increased interest in developing living-donor kidney transplantation (LDKT) programs. MATERIAL AND METHODS A total of 668 potential living kidney donors (PLKD) for 496 intended recipients were evaluated in a LDKT program between 2010 and 2014. Causes for PLKD exclusion were recorded, as well as patient survival. RESULTS After evaluation, 250 (37.4%) PLKD were considered suitable for kidney donation, 331 (49.6%) were excluded for medical reasons, and 87 (13.0%) withdrew their consent. The main cause of exclusion was metabolic syndrome and its components: 131 (39.6%) obesity, 37 (11.2%) new diagnosis of diabetes mellitus, and 25 (7.6%) new diagnosis of hypertension. Sixty-three (19.0%) were excluded for previously undetected renal diseases. Forty-six (13.9%) PLKD were excluded for immunological incompatibility. A total of 158 patients (31.9%) were transplanted from living donors and 31 (6.3%) from deceased donors (after the donor was considered non-suitable). Three-year patient survival was 99.4% for transplanted patients and 41.4% for patients who remained on dialysis. CONCLUSIONS Metabolic diseases constitute the main cause of donor exclusion in some LDKT programs. The high mortality rate of patients whose donor is excluded renews the debate over expanding donor criteria against the long-term risks they may pose to the living kidney donor.

Potential deceased donor management optimization is important for organ recovery maximization. Before optimization, the current state of donor management and predictors for organ recovery require analysis. We retrospectively analyzed organ procurement activity and medical management for 2005 to 2010 potential brain death donors at Seoul National University Hospital. Of 316 contacts for potential brain-dead donors, 129 (39.7%) patients were transferred to the donor management team. Among the causes of transfer failure, issues related to proper donor management affected 33%. Expanded criteria donors were 17.9% of transferred donors. Organ recovery was successful in 111 (90.2%) donors. A total of 360 organs were recovered, corresponding to a mean of 2.92 ± 1.37 organs per donor. The absence of organ demand was an important cause of recovery failure among less transplanted organs. Brain death-related complications were identified as follows: acute kidney injury (AKI), defined by AKI network criteria, occurred in 19 (15.4%); cardiopulmonary resuscitation in 5 (3.1%); bacteremia in 12 (9.7%); thrombocytopenia in 24 (19.5%); and diabetes insipidus in 42 (34.1%). AKI was a significant independent risk factor for organ recovery failure in both the liver and kidney (odds ratio [OR] 0.147, 95% confidence interval [0.045, 0.473], P = .001; OR 0.096, 95% confidence interval [0.023, 0.392], P = .001, for kidney and liver, respectively). Both the transfer success rate and rate of organs transplanted per donor of potential deceased donors remained low in Korea. AKI during potential donor management was a risk factor for kidney and liver recovery failure. Copyright © 2012 Elsevier Inc. All rights reserved.

Live donor kidney transplantation (LDKT), an optimal therapy for many patients with end-stage kidney disease, is underutilized, particularly by African Americans. Potential recipient difficulties initiating and sustaining conversations about LDKT, identifying willing and medically eligible donors, and potential donors' logistical and financial hurdles have been cited as potential contributors to race disparities in LDKT. Few interventions specifically targeting these factors have been tested. We report the protocol of the Talking about Living Kidney Donation Support (TALKS) study, a study designed to evaluate the effectiveness of behavioral, educational and financial assistance interventions to improve access to LDKT among African Americans on the deceased donor kidney transplant recipient waiting list. We adapted a previously tested educational and social worker intervention shown to improve consideration and pursuit of LDKT among patients and their family members for its use among patients on the kidney transplant waiting list. We also developed a financial assistance intervention to help potential donors overcome logistical and financial challenges they might face during the pursuit of live kidney donation. We will evaluate the effectiveness of these interventions by conducting a randomized controlled trial in which patients on the deceased donor waiting list receive 1) usual care while on the transplant waiting list, 2) the educational and social worker intervention, or 3) the educational and social worker intervention plus the option of participating in the financial assistance program. The primary outcome of the randomized controlled trial will measure potential recipients' live kidney donor activation (a composite rate of live donor inquiries, completed new live donor evaluations, or live kidney donation) at 1 year. The TALKS study will rigorously assess the effectiveness of promising interventions to reduce race disparities in LDKT. NCT02369354.

Organ transplantation has prolonged and improved the lives of many patients around the world. However, a widespread shortage of donors remains the main factor that has led to organ trafficking and transplant tourism. To stop transplant tourism and to provide optimal treatment for its citizens with end-stage renal disease, Montenegro started performing renal transplantations in September 2012. Thirty-five transplantations have been performed since that time, 34 from living donors and only 1 from a deceased donor. This practice has significantly decreased but not ended transplant tourism in Montenegro. Copyright © 2018 Elsevier Inc. All rights reserved.

The acceptability of financial incentives for organ donation is contentious. This study sought to determine (1) the acceptability of expense reimbursement or financial incentives by the general public, health professionals involved with organ donation and transplantation, and those with or affected by kidney disease and (2) for the public, whether financial incentives would alter their willingness to consider donation. Web-based survey administered to members of the Canadian public, health professionals, and people with or affected by kidney disease asking questions regarding acceptability of strategies to increase living and deceased kidney donation and willingness to donate a kidney under various financial incentives. Responses were collected from 2004 members of the Canadian public October 11-18, 2011; responses from health professionals (n=339) and people with or affected by kidney disease (n=268) were collected during a 4-week period commencing October 11, 2011. Acceptability of one or more financial incentives to increase deceased and living donation was noted in >70% and 40% of all groups, respectively. Support for monetary payment for living donors was 45%, 14%, and 27% for the public, health professionals, and people with or affected by kidney disease, respectively. Overall, reimbursement of funeral expenses for deceased donors and a tax break for living donors were the most acceptable. The general public views regulated financial incentives for living and deceased donation to be acceptable. Future research needs to examine the impact of financial incentives on rates of deceased and living donors.

Having enjoyed considerable success in kidney transplantation in recent years, Iran has been named the most active country in the Middle East Society for Organ Transplantation region in providing equitable quick, and intermediary-free access to affordable kidney transplantation for everyone regardless of gender and economic circumstances. We are, however, of the opinion that the Iranian model can benefit further from improving deceased-donor kidney transplantation, especially after a fatwa (Islamic edict) in the early 1980s lifted many religious and legal barriers. Deceased-donor kidney transplantation in Iran should be bolstered by establishing a transplantation model, increasing government funds, and encouraging participation of the general public in the Iranian Network for Transplant Organ Procurement. We recommend that an intensive media campaign be launched to heighten public awareness and more transplantation centres be involved in cadaveric transplantation with streamlined systems of cadaveric donations registration so as to facilitate the process of finding and relating the donors with potential recipients.

Finding long chains in kidney exchange using the traveling salesman problem.

2015-01-20

As of May 2014 there were more than 100,000 patients on the waiting list for a kidney transplant from a deceased donor. Although the preferred treatment is a kidney transplant, every year there are fewer donors than new patients, so the wait for a transplant continues to grow. To address this shortage, kidney paired donation (KPD) programs allow patients with living but biologically incompatible donors to exchange donors through cycles or chains initiated by altruistic (nondirected) donors, thereby increasing the supply of kidneys in the system. In many KPD programs a centralized algorithm determines which exchanges will take place to maximize the total number of transplants performed. This optimization problem has proven challenging both in theory, because it is NP-hard, and in practice, because the algorithms previously used were unable to optimally search over all long chains. We give two new algorithms that use integer programming to optimally solve this problem, one of which is inspired by the techniques used to solve the traveling salesman problem. These algorithms provide the tools needed to find optimal solutions in practice.

2012-02-15

We sought to determine the deceased donor factors associated with outcome after kidney transplantation and to develop a clinically applicable Kidney Donor Risk Index. Data from the UK Transplant Registry on 7620 adult recipients of adult deceased donor kidney transplants between 2000 and 2007 inclusive were analyzed. Donor factors potentially influencing transplant outcome were investigated using Cox regression, adjusting for significant recipient and transplant factors. A United Kingdom Kidney Donor Risk Index was derived from the model and validated. Donor age was the most significant factor predicting poor transplant outcome (hazard ratio for 18-39 and 60+ years relative to 40-59 years was 0.78 and 1.49, respectively, P<0.001). A history of donor hypertension was also associated with increased risk (hazard ratio 1.30, P=0.001), and increased donor body weight, longer hospital stay before death, and use of adrenaline were also significantly associated with poorer outcomes up to 3 years posttransplant. Other donor factors including donation after circulatory death, history of cardiothoracic disease, diabetes history, and terminal creatinine were not significant. A donor risk index based on the five significant donor factors was derived and confirmed to be prognostic of outcome in a validation cohort (concordance statistic 0.62). An index developed in the United States by Rao et al., Transplantation 2009; 88: 231-236, included 15 factors and gave a concordance statistic of 0.63 in the UK context, suggesting that our much simpler model has equivalent predictive ability. A Kidney Donor Risk Index based on five donor variables provides a clinically useful tool that may help with organ allocation and informed consent.

Unlike the United States, the potential to increase organ donation in Canada may be sufficient to meet the need for transplantation. However, there has been no national coordinated effort to increase organ donation. Strategies that do not involve payment for organs, such as investment in health care resources to support deceased donor organ donation and introduction of a remuneration framework for the work of deceased organ donation, should be prioritized for implementation. Financial incentives that may be permitted under existing legislation and that pose little risk to existing donation sources should be advanced, including the following: payment of funeral expenses for potential donors who register their decision on organ donation during life (irrespective of the decision to donate or actual organ donation) and removal of disincentives for directed and paired exchange living donation, such as payment of wages, payment for pain and suffering related to the donor surgery, and payment of directed living kidney donors for participation in Canada's paired exchange program. In contrast, it would be premature to contemplate a regulated system of organ sales that would require a paradigm shift in the current approach to organ donation and legislative change to implement.

Deceased organ donors are routinely screened for behaviors that increase the risk of transmissible blood-borne viral (BBV) infection, but the impact of this information on organ donation and transplant outcome is not well documented. Our aim was to establish the impact of such behavior on organ donation and utilization, as well transplant recipient outcomes. We identified all UK deceased organ donors from 2003 to 2015 with a disclosed history of increased risk behavior (IRB) including intravenous drug use (IVDU), imprisonment and increased risk sexual behavior. Of 17 262 potential donors, 659 (3.8%) had IRB for BBV and 285 (1.7%) were seropositive for BBV, of whom half had a history of IRB (mostly IVDU [78.5%]). Of actual donors with IRB, 393 were seronegative for viral markers at time of donation. A history of recent IVDU was associated with fewer potential donors proceeding to become actual organ donors (64% vs 75%, P = 0.007). Donors with IRB provided 1091 organs for transplantation (624 kidneys and 467 other organs). Transplant outcome was similar in recipients of organs from donors with and without IRB. There were 3 cases of unexpected hepatitis C virus transmission, all from an active IVDU donor who was hepatitis C virus seronegative at time of donation, but was found to be viremic on retrospective testing. Donors with a history of IRB provide a valuable source of organs for transplantation with good transplant outcomes and there is scope for increasing the use of organs from such donors.

Elevated alanine aminotransferase (ALT) in the deceased donor: impact on early post-transplant liver allograft function.

Serum alanine aminotransferase (ALT) levels are frequently elevated with liver injury and such elevations are common in deceased organ donors. The impact of this injury on early liver allograft function has not been well described. This study analyses the immediate function and 1-year graft and patient survival for liver allografts stratified by peak serum ALT levels in the deceased donor. The on-site organ procurement records for 1348 consecutive deceased liver donors were reviewed (2001–2011). Serum ALT was categorized into three study groups: normal/mild elevation, 0–499 μ/L; moderate elevation, 500–999 μ/L (>10× upper limit of normal) and severe elevation, ≥1000 μ/L (>20× upper limit of normal). Outcomes included early graft function and graft loss, and 1-year graft and patient survival. Distribution of subjects included: normal/mild, 1259 (93%); moderate, 34 (3%) and severe, 55 (4%). Risk of 30-day graft loss for the three study groups was: 72 (6%), 3 (9%) and 3 (6%) (P = 0.74). Graft and patient survival at 1 year for the three groups was: normal/mild, 1031 (87%), 1048 (88%); moderate, 31 (91%), 31 (91%) and severe, 43 (88%), 44 (90%) (P = 0.71, 0.79). Cox proportional hazards modelling of survival while controlling for donor age and recipient model for end-stage liver disease score (MELD) demonstrates no statistically significant difference among the three study groups. This study demonstrates clinical equivalence in early graft function and 1-year graft and patient survival for donor livers with varying peak levels of serum ALT. These donor allografts may, therefore, be utilized successfully.

Should Deceased Donation be Morally Preferred in Uterine Transplantation Trials?

PubMed Central

2016-01-01

Abstract In recent years much research has been undertaken regarding the feasibility of the human uterine transplant (UTx) as a treatment for absolute uterine factor infertility (AUFI). Should it reach clinical application this procedure would allow such individuals what is often a much‐desired opportunity to become not only social mothers (via adoption or traditional surrogacy arrangements), or genetic and social mothers (through gestational surrogacy) but mothers in a social, genetic and gestational sense. Like many experimental transplantation procedures such as face, hand, corneal and larynx transplants, UTx as a therapeutic option falls firmly into the camp of the quality of life (QOL) transplant, undertaken with the aim, not to save a life, but to enrich one. However, unlike most of these novel procedures – where one would be unlikely to find a willing living donor or an ethics committee that would sanction such a donation – the organs to be transplanted in UTx are potentially available from both living and deceased donors. In this article, in the light of the recent nine‐case research trial in Sweden which used uteri obtained from living donors, and the assertions on the part of a number of other research teams currently preparing trials that they will only be using deceased donors, I explore the question of whether, in the case of UTx, there exist compelling moral reasons to prefer the use of deceased donors despite the benefits that may be associated with the use of organs obtained from the living.

Two apolipoprotein L1 gene (APOL1) renal-risk variants in donors and African American (AA) recipient race are associated with worse allograft survival in deceased-donor kidney transplantation (DDKT) from AA donors. To detect other factors impacting allograft survival from deceased AA kidney donors, APOL1 renal-risk variants were genotyped in additional AA kidney donors. The APOL1 genotypes were linked to outcomes in 478 newly analyzed DDKTs in the Scientific Registry of Transplant Recipients. Multivariate analyses accounting for recipient age, sex, race, panel-reactive antibody level, HLA match, cold ischemia time, donor age, and expanded criteria donation were performed. These 478 transplantations and 675 DDKTs from a prior report were jointly analyzed. Fully adjusted analyses limited to the new 478 DDKTs replicated shorter renal allograft survival in recipients of APOL1 2-renal-risk-variant kidneys (hazard ratio [HR], 2.00; P = 0.03). Combined analysis of 1153 DDKTs from AA donors revealed donor APOL1 high-risk genotype (HR, 2.05; P = 3 × 10), older donor age (HR, 1.18; P = 0.05), and younger recipient age (HR, 0.70; P = 0.001) adversely impacted allograft survival. Although prolonged allograft survival was seen in many recipients of APOL1 2-renal-risk-variant kidneys, follow-up serum creatinine concentrations were higher than that in recipients of 0/1 APOL1 renal-risk-variant kidneys. A competing risk analysis revealed that APOL1 impacted renal allograft survival, but not recipient survival. Interactions between donor age and APOL1 genotype on renal allograft survival were nonsignificant. Shorter renal allograft survival is reproducibly observed after DDKT from APOL1 2-renal-risk-variant donors. Younger recipient age and older donor age have independent adverse effects on renal allograft survival.

Living donor liver transplant (LDLT) is the way forward in Asia.

Living donor liver transplantation (LDLT) is currently the commonest form of liver transplantation in Asia. Efforts to improve the number of deceased donor liver transplantation have not been uniformly successful. We believe that THE unique combination of demographic, social, economic and political factors that exist in Asia will ensure that LDLT will continue to remain the predominant form of liver transplantation. While efforts to increase deceased donation rates should continue and intensify, progress in LDLT should also be supported and encouraged, as it will be the main workhorse of liver transplantation in Asia in the near and medium-term future.

Summary Background and objective The acceptability of financial incentives for organ donation is contentious. This study sought to determine (1) the acceptability of expense reimbursement or financial incentives by the general public, health professionals involved with organ donation and transplantation, and those with or affected by kidney disease and (2) for the public, whether financial incentives would alter their willingness to consider donation. Design, setting, participants, & measurements Web-based survey administered to members of the Canadian public, health professionals, and people with or affected by kidney disease asking questions regarding acceptability of strategies to increase living and deceased kidney donation and willingness to donate a kidney under various financial incentives. Results Responses were collected from 2004 members of the Canadian public October 11–18, 2011; responses from health professionals (n=339) and people with or affected by kidney disease (n=268) were collected during a 4-week period commencing October 11, 2011. Acceptability of one or more financial incentives to increase deceased and living donation was noted in >70% and 40% of all groups, respectively. Support for monetary payment for living donors was 45%, 14%, and 27% for the public, health professionals, and people with or affected by kidney disease, respectively. Overall, reimbursement of funeral expenses for deceased donors and a tax break for living donors were the most acceptable. Conclusion The general public views regulated financial incentives for living and deceased donation to be acceptable. Future research needs to examine the impact of financial incentives on rates of deceased and living donors. PMID:23024166

Deceased donor kidneys with AKI are often discarded for fear of poor transplant outcomes. Donor biomarkers that predict post-transplant renal recovery could improve organ selection and reduce discard. We tested whether higher levels of donor urinary YKL-40, a repair phase protein, associate with improved recipient outcomes in a prospective cohort study involving deceased kidney donors from five organ procurement organizations. We measured urinary YKL-40 concentration in 1301 donors (111 had AKI, defined as doubling of serum creatinine) and ascertained outcomes in the corresponding 2435 recipients, 756 of whom experienced delayed graft function (DGF). Donors with AKI had higher urinary YKL-40 concentration (P<0.001) and acute tubular necrosis on procurement biopsies (P=0.05). In fully adjusted analyses, elevated donor urinary YKL-40 concentration associated with reduced risk of DGF in both recipients of AKI donor kidneys (adjusted relative risk, 0.51 [95% confidence interval (95% CI), 0.32 to 0.80] for highest versus lowest YKL-40 tertile) and recipients of non-AKI donor kidneys (adjusted relative risk, 0.79 [95% CI, 0.65 to 0.97]). Furthermore, in the event of DGF, elevated donor urinary YKL-40 concentration associated with higher 6-month eGFR (6.75 [95% CI, 1.49 to 12.02] ml/min per 1.73 m2) and lower risk of graft failure (adjusted hazard ratio, 0.50 [95% CI, 0.27 to 0.94]). These findings suggest that YKL-40 is produced in response to tubular injury and is independently associated with recovery from AKI and DGF. If ultimately validated as a prognostic biomarker, urinary YKL-40 should be considered in determining the suitability of donor kidneys for transplant. PMID:27451287

Deceased donor organ transplantation (DDOT) accounts for <4% of renal transplants in India. Many volunteers come forth for organ donation with increasing awareness; unfortunately, the majority are marginal donors, but their rejection would hamper the DDOT program. Judicious use of marginal organs is a challenge for developing countries. We performed 29 renal transplants from 21 expanded criteria donors (ECD) out of 115 DDOT between January 2006 to April 2009-10 dual (DKT) and 19 single (SKT). Fourteen donors had hypertension, a cerebrovascular accident as the cause of death, 9 had both, and 4 had diabetes. Mean donor age was 70.3 +/- 8.9 years. Decisions on the procedure were based upon frozen section biopsy in 13 of 21 donors. Mean DKT donor age was 76 +/- 9.7 years versu 64 +/- 5.7 years of SKT donors. The native kidney diseases were chronic glomerulonephritis (n = 14), diabetic nephropathy (n = 7), tubulointerstitial nephritis (n = 4) and polycystic kidney disease, focal segmental glomerulosclerosis, lupus nephritis and patchy cortical necrosis, (n = 1 each). Mean recipient age of DKT versus SKT was 43.5 versus 42.3 years. All recipients received rabbit anti-thymocyte globulin, followed by steroid, mycophenolate mofetil/calcinueurin inhibitor. Over a mean follow-up of 341 days, the mean serum creatinine (SCr) of 25/29 patients was 1.60 mg/dL (range, 1.0-2.6). The mean SCr of SKT patients was 1.59 +/- 0.63 mg/dL and of DKT, 1.62 +/- 0.48 mg/dL. Ten patients had delayed graft function and 11 had biopsy proven acute tubular necrosis. Seven (24%) patients had rejection (grade 3 Banff update '05, type IA; 4, type 2A); 6 responded to antirejection; 1 graft was lost at 7 months due to chronic rejection. Three (10.3%) patients were lost, 1 each due to AMI, sepsis, and CMV disease. In the circumstances of organ shortage, DDOT with expanded criteria donor is a feasible option.

Background and objectives Prior living donors (PLDs) receive very high priority on the Organ Procurement and Transplantation Network (OPTN) kidney waiting list. Program delays in adding PLDs to the waiting list, setting their status to active, and submitting requests for PLD priority can affect timely access to transplantation. Design, setting, participants, & measurements We used the OPTN and the Centers for Medicare and Medicaid Services data to examine timing of (1) listing relative to start of dialysis, (2) activation on the waiting list, and (3) requests for PLD priority relative to listing date. There were 210 PLDs (221 registrations) added to the OPTN kidney waiting list between January 1, 2010 and July 31, 2015. Results As of September 4, 2015, 167 of the 210 PLDs received deceased donor transplants, six received living donor transplants, two died, five were too sick to transplant, and 29 were still waiting. Median waiting time to deceased donor transplant for PLDs was 98 days. Only 40.7% of 221 PLD registrations (n=90) were listed before they began dialysis; 68.3% were in inactive status for <90 days, 17.6% were in inactive status for 90–365 days, 8.6% were in inactive status for 1–2 years, and 5.4% were in inactive status for >2 years. Median time of PLDs waiting in active status before receiving PLD priority was 2 days (range =0–1450); 67.4% of PLDs received PLD priority within 7 days after activation, but 15.4% waited 8–30 days, 8.1% waited 1–3 months, 4.1% waited 3–12 months, and 5.0% waited >1 year in active status for PLD priority. After receiving priority, most were transplanted quickly. Median time in active status with PLD priority before deceased donor transplant was 23 days. Conclusions Fewer than one half of listed PLDs were listed before starting dialysis. Most listed PLDs are immediately set to active status and receive PLD priority quickly, but a substantial number spends time in active status without PLD priority or a large amount of time in inactive status, which affects access to timely transplants.

Red Kidney: Kidney Transplant From a Deceased Donor Who Received Massive Blood Transfusion During Cardiopulmonary Bypass.

PubMed

Bell, Richard; Hanif, Faisal; Prasad, Padmini; Ahmad, Niaz

2016-06-01

Here, we present a case of a deceased-donor kidney transplant. The brain-dead donor had received a massive blood transfusion during cardiopulmonary bypass, which lead to hemolysis, hemoglobinuria, acute kidney injury, and renal replacement therapy. The kidney appeared red after in situ flush. Postoperatively, the recipient developed delayed graft function. Protocol biopsy during the postoperative period revealed the widespread deposition of heme pigment in the renal tubules. Massive blood transfusion and cardiopulmonary bypass surgery are associated with hemolysis and heme pigment deposition in the renal tubules, which subsequently lead to acute kidney injury. Kidneys from such donors appear red and, while this does not preclude transplant, are likely to develop delayed graft function.

Occult hepatitis B virus infection is defined as detectable HBV-DNA in liver of HBsAg-negative individuals, with or without detectable serum HBV-DNA. In deceased liver donors, results of tissue analysis cannot be obtained prior to allocation for liver transplantation. we investigated prevalence and predictability of occult hepatitis B using blood markers of viral exposure/infection in deceased liver donors. In 50 consecutive HBsAg-negative/anti-HBc-positive and 20 age-matched HBsAg-negative/anti-HBc-negative donors, a nested-PCR assay was employed in liver biopsies for diagnosis of occult hepatitis B according to Taormina criteria. All donors were characterized for plasma HBV-DNA and serum anti-HBs/anti-HBe. In liver tissue, occult hepatitis B was present in 30/50 anti-HBc-positive (60%) and in 0/20 anti-HBc-negative donors (p<0.0001). All anti-HBc-positive donors with detectable HBV-DNA in plasma (n=5) or anti-HBs>1,000 mIU/mL (n=5) eventually showed occult infection, i.e, 10/30 occult hepatitis B-positive donors which could have been identified prior to transplantation. In the remaining 40 anti-HBc-positive donors, probability of occult infection was 62% for anti-HBe-positive and/or anti-HBs ≥ 58 mIU/mL; 29% for anti-HBe-negative and anti-HBs<58 mIU/mL. In deceased donors, combining anti-HBc with other blood markers of hepatitis B exposure/infection allows to predict occult hepatitis B with certainty and speed in one third of cases. These findings might help refine the allocation of livers from anti-HBc-positive donors. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd. All rights reserved.

Eighteen years experience of granulocyte donations-acceptable donor safety?

2015-10-01

Granulocyte transfusions are given to patients with life-threatening infections, refractory to treatment. The donors are stimulated with corticosteroids ± granulocyte colony stimulating factor (G-CSF). However, data regarding the donors' safety is sparse. The objective was therefore to evaluate short- and long-term adverse events (AE) in G-CSF stimulated donors. All consecutive granulocyte donors from 1994 to 2012 were identified through our registry. From the donation records, the number of aphereses, stimulation therapy, AE, blood values post donation, and recent status were evaluated. One hundred fifty-four volunteer donors were mobilized for 359 collections. Age at first granulocyte donation was 43 years (median; range 19-64 years). Follow-up was 60 months (median; range 0-229 months). The dose of G-CSF per collection was 3.8 ug/kg body weight (median; range 1.6-6.0 ug/kg). Sedimentation agent was HES. Short-term AE were mild. Blood values 4 weeks post donation with minor reductions/elevations mostly resolved in later donations. Fourteen donors were excluded from the registry due to hypertension (4), diabetes (2), atrial flutter (1), breast carcinoma (1), urethral carcinoma in situ (1), MGUS (1), thrombosis (1), anaphylaxis (1), primary biliary cirrhosis (1), and unknown (1). Three donors are deceased due to diabetes, acute myocardial infarction, and unknown cause. All excluded/deceased donors except one were excluded/died at least 6 months after first granulocyte donation. No serious short-term AE were observed. Due to the variability of diagnoses among excluded/deceased donors, we propose that it is less likely that granulocyte donations have a causative impact on these donors' exclusion or death. © 2014 Wiley Periodicals, Inc.

Expanding the live kidney donor pool: ethical considerations regarding altruistic donors, paired and pooled programs.

PubMed

Patel, Shaneel Rajendra; Chadha, Priyanka; Papalois, Vassilios

2011-06-01

In renal transplant, there is a well-known deficiency in organ supply relative to demand. Live donation provides superior results when compared with deceased donation including a better rate of graft success and fewer immunologic complications. This deficiency in organs leads to significant morbidity and mortality rates. Alternative avenues have been extensively explored that may expand the live donor pool. They include altruistic donation as well as paired and pooled exchange programs. Altruistic donation is a truly selfless act from a donor unknown to the recipient. Kidney paired donation involves 2 incompatible donor-recipient pairs swapping donors to produce compatibility. Pooled donation involves at least 2 pairs, and can take the form of domino chains in which altruistic input sets up a chain of transplants, in which each recipient's incompatible donor makes a donation for the next recipient. Despite application of these various methods, there lie extensive ethical issues surrounding them. Misconceptions frequently occur; for instance, the perceived benefit that donating an organ to a loved one is greater for a related donor than for an altruistic one. Additionally, it is frequently believed that immunologic incompatibility offers coerced donors liberation from surgery, and that overcoming these barriers by introducing exchange programs provides vulnerable donors less protection. This article explores these and other complex ethical issues surrounding the various methods of expanding the donor pool. The authors offer opinions that challenge the ethical issues and attempt to overcome those views that hinder progress in the field.

One third of healthy willing living kidney donors are rejected due to ABO blood group incompatibility and donor specific antibody. This increases pre-transplant dialysis duration leading to increased morbidity and mortality on the kidney transplantation waiting list. Over the last decade kidney paired donation is most rapidly increased source of living kidney donors. In a kidney transplantation program dominated by living donor kidney transplantation, kidney paired donation is a legal and valid alternative strategy to increase living donor kidney transplantation. This is more useful in countries with limited resources where ABO incompatible kidney transplantation or desensitization protocol is not feasible because of costs/infectious complications and deceased donor kidney transplantation is in initial stages. The matching allocation, ABO blood type imbalance, reciprocity, simultaneity, geography were the limitation for the expansion of kidney paired donation. Here we describe different successful ways to increase living donor kidney transplantation through kidney paired donation. Compatible pairs, domino chain, combination of kidney paired donation with desensitization or ABO incompatible transplantation, international kidney paired donation, non-simultaneous, extended, altruistic donor chain and list exchange are different ways to expand the donor pool. In absence of national kidney paired donation program, a dedicated kidney paired donation team will increase access to living donor kidney transplantation in individual centres with team work. Use of social networking sites to expand donor pool, HLA based national kidney paired donation program will increase quality and quantity of kidney paired donation transplantation. Transplant centres should remove the barriers to a broader implementation of multicentre, national kidney paired donation program to further optimize potential of kidney paired donation to increase transplantation of O group and sensitized patients. This review assists in the development of similar programs in other developing countries. PMID:28507916

Background There is a critical need to expand the pool of available kidneys for African Americans who are on the transplant wait-list due to the disproportionally lower availability of deceased donor kidneys compared with other races/ethnic groups. Encouraging living donation is one method to fill this need. Incorporating mHealth strategies may be a way to deliver educational and supportive services to African American transplant-eligible patients and improve reach to those living in remote areas or unable to attend traditional group-session-based programs. Before program development, it is essential to perform formative research with target populations to determine acceptability and cultivate a patient-centered and culturally relevant approach to be used for program development. Objective The objectives of this study were to investigate African American kidney transplant recipients’ and kidney donors’/potential donors’ attitudes and perceptions toward mobile technology and its viability in an mHealth program aimed at educating patients about the process of living kidney donation. Methods Using frameworks from the technology acceptance model and self-determination theory, 9 focus groups (n=57) were administered to African Americans at a southeastern medical center, which included deceased/living donor kidney recipients and living donors/potential donors. After a demonstration of a tablet-based video education session and explanation of a group-based videoconferencing session, focus groups examined members’ perceptions about how educational messages should be presented on topics pertaining to the process of living kidney donation and the transplantation. Questionnaires were administered on technology use and perceptions of the potential program communication platform. Transcripts were coded and themes were examined using NVivo 10 software. Results Qualitative findings found 5 major themes common among all participants. These included the following: (1) strong support for mobile technology use; (2) different media formats were preferred; (3) willingness to engage in video chats, but face-to-face interaction sometimes preferred; (4) media needs to be user friendly; (5) high prevalence of technology access. Our results show that recipients were willing to spend more time on education than the donors group, they wanted to build conversation skills to approach others, and preferred getting information from many sources, whereas the donor group wanted to hear from other living donors. The questionnaires revealed 85% or more of the sample scored 4+ on a 5-point Likert scale, which indicates high degree of interest to use the proposed program, belief that other mHealth technologies would help with adherence to medical regimens, and doctors would make regimen adjustments quicker. In addition, high utilization of mobile technology was reported; 71.9% of the participants had a mobile phone and 43.9% had a tablet. Conclusions Our study supports the use of an mHealth education platform for African Americans to learn about living donation. However, potential recipients and potential donors have differing needs, and therefore, programs should be tailored to each target audience. PMID:26265532

The UK Kidney Fast-Track Scheme (KFTS) was introduced in 2012 to identify kidneys at high risk of discard and to rapidly facilitate transplantation. A retrospective analysis of kidneys transplanted through the KFTS was undertaken. UK Transplant Registry data were collected on deceased donor kidneys implanted between November 1, 2012, and April 30, 2015, (donation after brain death [DBD] donors) and March 1, 2013, and April 30, 2015 (donation after circulatory death [DCD] donors). Posttransplant outcomes included 1-year estimated glomerular filtration rate and death-censored graft survival (DCGS). Over the study period, 523 deceased donor kidneys were transplanted through the KFTS and 4174 via the standard National Kidney Allocation Scheme (NKAS). Kidneys in the KFTS were more likely to be from older diabetic donors, had a higher frequency of poor ex vivo perfusion, had longer cold ischemic times, and were transplanted into older recipients. One-year DCGS of KFTS and NKAS DBD donor kidneys was similar (94% vs 95%; P = 0.70), but for DCD donor kidneys, DCGS was lower in those allocated via the KFTS (91% versus 95%; P = 0.04). Median 1-year estimated glomerular filtration rate for DBD donor kidneys was lower in those allocated via the KFTS (49 vs 52 mL/min per 1.73 m; P = 0.01), but for DCD kidneys, there was no difference (45 vs 48 mL/min per 1.73 m; P = 0.10). Although KFTS kidneys have less favorable donor, graft, and recipient risk factors than NKAS kidneys, short-term graft and patient outcomes are acceptable. National schemes that identify and rapidly offer kidneys at high risk of discard may contribute to minimizing the unnecessary discard of organs.

Transplanted tissues have transmitted transmissible spongiform encephalopathies and in the UK there have been more cases of variant Creutzfeldt-Jakob disease (vCJD) than elsewhere in the world. A pilot study was undertaken to look at the feasibility of testing for vCJD in deceased donors using tonsillar tissue. This pilot showed that obtaining consent for removal and testing tonsil tissue was feasible. Donor eligibility for inclusion in the pilot was limited to tissue donors from the National Health Service Blood and Transplant, Tissue Services and to donors shared with the Corneal Transplant Service Eye Banks. Obtaining tonsillar tissue in the immediate post-mortem period was limited by the presence of rigor mortis. Tonsillar tissue was suitable for routine analysis for the presence of prion associated with vCJD in deceased tissue donors. Production and processing of tissue was straightforward and a low assay background was obtained from most samples. Since palatine and lingual tonsil tissue can be obtained in pairs it was possible, in the majority of cases, to set aside an intact sample for confirmatory testing if required. In one instance a sample was reactive by Western blot. However, the pattern of reactivity was not typical for that obtained from vCJD patients. Unfortunately the sample was not of sufficient quality for the confirmatory test to provide a conclusive result.

The increasing incidence of end-stage kidney disease in Qatar has led to growing demand for donor kidneys. The deceased donor kidney program has yet to achieve its full potential; hence, living kidney donation has been widely adopted as an appropriate alternative. The reliance on living kidney donors however, raises a number of social, ethical, and legal concerns surrounding informed consent, voluntarism, psychosocial evaluation, perioperative care, and long-term follow-up of living kidney donors. Many of these concerns become heightened in a multicultural, multilingual society within a Gulf country such as Qatar. This article provides an insight into the challenges that living kidney donation poses in a multiethnic society with significant socioeconomic divides. It also discusses the remedial measures that the Qatari government, healthcare authorities, and transplant community have adopted to address these issues.

Donor-derived bacterial infection is a recognized complication of solid organ transplantation (SOT). The present report describes the clinical details and successful outcome in a liver transplant recipient despite transmission of methicillin-resistant Staphylococcus aureus (MRSA) from a deceased donor with MRSA endocarditis and bacteremia. We further describe whole genome sequencing (WGS) and complete de novo assembly of the donor and recipient MRSA isolate genomes, which confirms that both isolates are genetically 100% identical. We propose that similar application of WGS techniques to future investigations of donor bacterial transmission would strengthen the definition of proven bacterial transmission in SOT, particularly in the presence of highly clonal bacteria such as MRSA. WGS will further improve our understanding of the epidemiology of bacterial transmission in SOT and the risk of adverse patient outcomes when it occurs. PMID:25250641

There is a big controversy over liver retransplantation, the only life-saving treatment for patients with a failing or failed liver graft. This retrospective study tried to determine if living-donor liver retransplantation (re-LDLT) is a justifiable alternative to deceased-donor liver retransplantation (re-DDLT). Anonymous data of liver transplant patients from January 2000 to April 2016 were reviewed. Recipients of retransplantation were divided into the re-DDLT and re-LDLT groups. The groups were compared in demographic characteristics, pre-retransplant and intraoperative details, and short- and long-term outcomes. Risk for living donors was examined. Twenty-nine patients had 33 re-DDLTs and 15 patients received re-LDLT. The re-LDLT group had lighter grafts (525 vs. 1295 g, p ≤ 0.001), a smaller ratio of graft weight to recipient standard liver volume (56.98 vs. 107.7%, p ≤ 0.001), and shorter cold ischemia (106 vs. 451 min, p ≤ 0.001). The groups were otherwise comparable. Two patients in the re-DDLT group had Grade-5 complication. The groups were similar in patient survival (p = 0.326) and graft survival (p = 0.102). No living donors died, but three of them developed Grade-1 complications. With the required expertise, re-LDLT can produce results comparable to those of re-DDLT while keeping donor risk at bay. In places where the demand for deceased-donor liver grafts far outstrips supply, re-LDLT can be considered as an alternative to re-DDLT if the expertise is available and if the potential recipient benefits can balance out the potential donor risks.

The experience of receiving a kidney transplant from a deceased donor: Implications for renal services.

The study aimed to explore the psychological experiences of receiving a kidney transplant from a deceased donor and to examine resulting implications for renal services. A qualitative design was utilised within an interpretative phenomenological analysis (IPA) framework. Semi-structured interviews were conducted with six adults (male = 5, mean age = 45 yrs) on their experiences of receiving a kidney transplant from a deceased donor. All participants had their transplant within the preceding 21 months. Data were analysed using IPA. The four elicited themes incorporate recipients' positive feelings about receiving a transplant, mainly arising from the newfound freedom that this entails, in addition to strong feelings of gratitude towards their donors. They also capture challenges, such as the uncertainty of living with a transplanted kidney, and highlight the increased dependence on others throughout the transplant process. The findings indicate a range of psychological, social and occupational experiences for participants. It is concluded that optimal care in renal services would incorporate a holistic approach to pre and post-transplant care; identifying and supporting the needs of transplant recipients. A biopsychosocial model of care may enhance service user well-being. Potential areas of future research are explored.

When do next-of-kin opt-in? Anticipated regret, affective attitudes and donating deceased family member's organs.

This research assessed whether affective factors promote and prevent family members from donating their loved one's organs. Participants (N = 191) imagined that a family member had died and that they had to decide whether or not to donate their organs and body parts for transplantation purposes. The least organs and body parts were donated when the deceased opposed donation. Moreover, participants who were not registered organ donors donated fewer organs than registered donors. This effect was mediated by anticipated regret, disgust and the perceived benefits of donation. Organ donation campaigns should target such factors to increase donor rates. © The Author(s) 2013.

Background and objectives: Variation in kidney transplant access across the United States may motivate relocation of patients with ability to travel to better-supplied areas. Design, setting, participants, & measurements: We examined national transplant registry and U.S. Census data for kidney transplant candidates listed in 1999 to 2009 with a reported residential zip code (n = 203,267). Cox's regression was used to assess associations of socioeconomic status (SES), distance from residence to transplant center, and relocation to a different donation service area (DSA) with transplant access and outcomes. Results: Patients in the highest SES quartile had increased access to transplant compared with those with lowest SES, driven strongly by 76% higher likelihood of living donor transplantation (adjusted hazard ratio [aHR] 1.76, 95% confidence interval [CI] 1.70 to 1.83). Waitlist death was reduced in high compared with low SES candidates (aHR 0.86, 95% CI 0.84 to 0.89). High SES patients also experienced lower mortality after living and deceased donor transplant. Patients living farther from the transplant center had reduced access to deceased donor transplant and increased risk of post-transplant death. Inter-DSA travel was associated with a dramatic increase in deceased donor transplant access (HR 1.94, 95% CI 1.88 to 2.00) and was predicted by high SES, white race, and longer deceased-donor allograft waiting time in initial DSA. Conclusions: Ongoing disparities exist in kidney transplantation access and outcomes on the basis of geography and SES despite near-universal insurance coverage under Medicare. Inter-DSA travel improves access and is more common among high SES candidates. PMID:20798250

Hispanic patients undergoing chronic dialysis are less likely to receive a kidney transplant compared with non-Hispanic whites. This study sought to elucidate disparities in the path to receipt of a deceased donor transplant between Hispanic and non-Hispanic whites. Using the US Renal Data System, 417,801 Caucasians who initiated dialysis between January 1, 1995 and December 31, 2007 with follow-up through 2008 were identified. This study investigated time from first dialysis to first kidney transplantation, time from first dialysis to waitlisting, and time from waitlisting to kidney transplantation. Multivariable Cox regression estimated cause-specific hazard ratios (HRCS) and subdistribution (competing risk) hazard ratios (HRSD) for Hispanics versus non-Hispanic whites. Hispanics experienced lower adjusted rates of deceased donor kidney transplantation than non-Hispanic whites (HRCS, 0.77; 95% confidence interval [95% CI], 0.75 to 0.80) measured from dialysis initiation. No meaningful differences were found in time from dialysis initiation to placement on the transplant waitlist. Once waitlisted, Hispanics had lower adjusted rates of deceased donor kidney transplantation (HRCS, 0.66; 95% CI, 0.64 to 0.68), and the association attenuated once accounting for competing risks (HRSD, 0.79; 95% CI, 0.77 to 0.81). Additionally controlling for blood type and organ procurement organization further reduced the disparity (HRSD, 0.99; 95% CI, 0.96 to 1.02). After accounting for geographic location and controlling for competing risks (e.g., Hispanic survival advantage), the disparity in access to deceased donor transplantation was markedly attenuated among Hispanics compared with non-Hispanic whites. To overcome the geographic disparities that Hispanics encounter in the path to transplantation, organ allocation policy revisions are needed to improve donor organ equity.

There is a widening gap between the needs and possibilities of kidney transplantation. In order to solve the problem of organ shortage, the selection criteria for kidney donors have been less stringent over the last years. Favorable outcome of renal transplantation from deceased donors with acute renal failure requiring dialysis may have an important role in expanding the pool of donors. We present the case of two renal transplantations from a polytraumatized 20-years old donor with acute renal failure requiring dialysis. One recipient established good diuresis from the first post-transplant day and did not require hemodialysis. The second recipient had delayed graft function and was treated with 8 hemodialysis sessions. The patient was discharged with good diuresis and normal serum creatinine. After two years of follow-up, both recipients have normal graft function. According to our experience, kidneys from deceased young donors with acute renal failure requiring dialysis may be transplanted, in order to decrease the number of patients on transplantation waiting lists.

Federal legislation has been proposed to modify the National Organ Transplant Act in a way that would permit government-regulated strategies, including financial incentives, to be implemented and evaluated. The Council and Ethics Committee of the American Society of Transplant Surgeons conducted a brief web-based survey of its members' (n = 449, 41.6% response rate) views on acceptable or unacceptable strategies to increase organ donation. The majority of the membership supports reimbursement for funeral expenses, an income tax credit on the final return of a deceased donor and an income tax credit for registering as an organ donor as strategies for increasing deceased donation. Payment for lost wages, guaranteed health insurance and an income tax credit are strategies most strongly supported by the membership to increase living donation. For both deceased and living donation, the membership is mostly opposed to cash payments to donors, their estates or to next-of-kin. There is strong support for a government-regulated trial to evaluate the potential benefits and harms of financial incentives for both deceased and living donation. Overall, there is strong support within the ASTS membership for changes to NOTA that would permit the implementation and careful evaluation of indirect, government-regulated strategies to increase organ donation.

In 2010 the formation of the Polish Hospitals Network of Organ Donation Coordinators, originated by Poltransplant, began. One of the goals of this project is to report all deaths in hospital ICUs in which a coordinator is posted. The aim of this strategy is to monitor donation potential, following the recruitment process of potential donors and indicating stages of that process that may be improved to increase effective recruitment. Until the end of 2014 all data were forwarded to Poltransplant as Excel files, but since January 1, 2015, reporting and data collection have been are performed using web tool www.koordynator.net. The aim of the paper is to present the essentials in functioning principles, structure, and usage of the www.koordynator.net system, its technical construction, and to display good practices (know-how) tested by 1 country, for countries such as Poland, that contend with organ insufficiency. The application www.koordynator.net allows for remote addition of individual records with information about deceased patients in hospital ICUs, the forwarding of data about potential and actual organ donors, the generation of complete reports about deceased patients in each hospital monthly, and the introduction of historical data. Introduction of a potential donation monitoring system in 209 hospitals with transplant coordinators increases the number of identified potential and effective actual donors due to self-assessment analysis. Eventually, the www.koordynator.net reporting system allowed for external evaluation by coordinators from other hospitals, regional coordinators, and Poltransplant. The system is a modern tool that improves and increases the quality system in the organ donation field (quality assurance program). Copyright © 2016 Elsevier Inc. All rights reserved.

Donation after cardiac death as a strategy to increase deceased donor liver availability.

2006-10-01

This study examines donation after cardiac death (DCD) practices and outcomes in liver transplantation. Livers procured from DCD donors have recently been used to increase the number of deceased donors and bridge the gap between limited organ supply and the pool of waiting list candidates. Comprehensive evaluation of this practice and its outcomes has not been previously reported. A national cohort of all DCD and donation after brain-death (DBD) liver transplants between January 1, 2000 and December 31, 2004 was identified in the Scientific Registry of Transplant Recipients. Time to graft failure (including death) was modeled by Cox regression, adjusted for relevant donor and recipient characteristics. DCD livers were used for 472 (2%) of 24,070 transplants. Annual DCD liver activity increased from 39 in 2000 to 176 in 2004. The adjusted relative risk of DCD graft failure was 85% higher than for DBD grafts (relative risk, 1.85; 95% confidence interval, 1.51-2.26; P < 0.001), corresponding to 3-month, 1-year, and 3-year graft survival rates of 83.0%, 70.1%, and 60.5%, respectively (vs. 89.2%, 83.0%, and 75.0% for DBD recipients). There was no significant association between transplant program DCD liver transplant volume and graft outcome. The annual number of DCD livers used for transplant has increased rapidly. However, DCD livers are associated with a significantly increased risk of graft failure unrelated to modifiable donor or recipient factors. Appropriate recipients for DCD livers have not been fully characterized and recipient informed consent should be obtained before use of these organs.

Commercial renal transplantation: A risky venture? A single Canadian centre experience.

Canada, akin to other developed nations, faces the growing challenges of end-stage renal disease (ESRD). Even with expanded donor criteria for renal transplantation (the treatment of choice for ESRD), the supply of kidneys is outpaced by the escalating demand. Remuneration for kidney donation is proscribed in Canada. Without an option of living-related transplantation (biological or emotional donors), patients often struggle with long waiting lists for deceased donor transplantation. Accordingly, many patients are now opting for more expedient avenues to obtaining a renal transplant. Through commercial organ retrieval programs, from living and deceased donors, patients are travelling outside Canada to have the procedure performed. Between September 2001 and July 2007, 10 patients (7 males, 3 females) underwent commercial renal transplantation outside Canada. We describe the clinical outcomes of these patients managed postoperatively at our single Canadian transplant centre. Six living unrelated and 4 deceased donor renal transplantations were performed on these 10 patients (mean age 49.5 years). All procedures were performed in developing countries and the postoperative complications were subsequently treated at our centre. The mean post-transplant serum creatinine was 142 μmol/L. The average follow-up time was 29.8 months (range: 3 to 73 months). One patient required a transplant nephrectomy secondary to fungemia and subsequently died. One patient had a failed transplant and has currently resumed hemodialysis. Acute rejection was seen in 5 patients with 3 of these patients requiring re-initiation of hemodialysis. Only 1 patient had an uncomplicated course after surgery. Despite the kidney trade being a milieu of corruption and commercialization, and the high risk of unconventional complications, patients returning to Canada after commercial renal transplantation are the new reality. Patients are often arriving without any documentation; therefore, timely, goal-directed therapy for surgical and infectious complications is frequently delayed because of the time taken to establish an accurate diagnosis. Refuting the existence of commercial renal transplantation may not be a practical solution; more consistent communication and documentation with transplant teams may be more pragmatic. In the current climate, patients considering the option of overseas commercial renal transplantation should be advised of the potential increased risks.

The efforts in the late 1940s to 1960s of two Parisian pioneers in kidney transplantation, René Kűss, a surgeon, and Jean Hamburger, a nephrologist, have largely been forgotten. Küss developed the operation that is basically unchanged today. Both groups initiated clinical transplant programs in January 1951, and both were among the first to carry out kidney transplantation (i) without immunosuppressive therapy, (ii) between living-related and unrelated donors, (iii) with organs from deceased donors, (iv) with irradiation and immunosuppressive drugs, and (v) with long-term survival. In the opinion of many, the French did not receive full credit for their work internationally.

Liver transplantation in Japan.

2016-10-01

As of December 31, 2014, 7937 liver transplants (7673 living donor transplants and 264 deceased donor liver transplantations [DDLTs; 261 from heart-beating donors and 3 from non-heart-beating donors]) have been performed in 67 institutions in Japan. The revised Organ Transplant Law in Japan came into effect in July 2010, which allows organ procurement from brain-dead individuals, including children, with family consent if the patient had not previously refused organ donation. However, the number of deceased donor organ donations has not increased as anticipated. The rate of deceased organ donations per million population (pmp) has remained at less than 1. To maximize the viability of the limited numbers of donated organs, a system has been adopted that includes the partnership of well-trained transplant consultant doctors and local doctors. For compensating for the decreased opportunity of on-site training, an educational system regarding quality organ procurement for transplant surgeons has also been established. Furthermore, experts in the field of liver transplantation are currently discussing adoption of the Model for End-Stage Liver Disease score for allocation, promoting split-liver transplantation, arranging in-house coordinators, and improving the frequency of proposing the option to donate organs to the families. To overcome the shortage of donors during efforts to promote organ donation, living donor liver transplantation (LDLT) has been developed in Japan. Continuous efforts to increase DDLT in addition to the successful experience of LDLT will increase the benefits of liver transplantation for more patients.

There were 13 documented clusters of infectious encephalitis transmission via organ transplant from deceased donors to recipients during 2002-2013. Hence, organs from donors diagnosed with encephalitis are often declined due to concerns about the possibility of infection, given that there is no quick and simple test to detect causes of infectious encephalitis. We constructed a database containing cases of infectious and non-infectious encephalitis. Using statistical imputation, cross-validation, and regression techniques, we determined deceased organ donor characteristics, including demographics, signs, symptoms, physical exam, and laboratory findings, predictive of infectious versus non-infectious encephalitis, and developed a calculator which assesses risk of infection. Using up to 12 predictive patient characteristics, (with a minimum of 3, depending on what information is available), the calculator provides the probability that a donor may have infectious versus non-infectious encephalitis, improving the prediction accuracy over current practices. These characteristics include gender, fever, immunocompromised state (other than HIV), cerebrospinal fluid elevation, altered mental status, psychiatric features, cranial nerve abnormality, meningeal signs, focal motor weakness, Babinski's sign, movement disorder, and sensory abnormalities. In the absence of definitive diagnostic testing in a potential organ donor, infectious encephalitis can be predicted with a risk score. The risk calculator presented in this paper represents a prototype, establishing a framework that can be expanded to other infectious diseases transmissible through solid organ transplantation.

Increasing the pool of deceased donor organs for kidney transplantation.

PubMed

Schold, Jesse D; Segev, Dorry L

2012-03-27

Expanding the pool of available deceased donor kidneys is critical for improving the outcomes of prospective and current renal transplant candidates. A number of interventions have been proposed that may increase the pool of donors in the US. However, these interventions have variable levels of empirical evidence supporting their potential beneficial impact. Proposed interventions include the instigation of policies for presumed donor consent, the expansion of donor registration, increased quality oversight of transplant providers, financial incentives for donors, increased reimbursement for higher risk donors, alterations in organ allocation policies and distribution, and the selective use of donors with potential or known risk for disease transmission. Many of these interventions have contentious elements that may have delayed or impeded their implementation; however, these options should be considered in the context of the diminishing prognoses for prospective transplant patients, given the increasing scarcity of donor organs relative to the population need. In this Review, we outline the proposed interventions and briefly discuss salient issues that characterize the debates concerning their implementation and effectiveness. Ultimately, any intervention must be based on the best evidence available, with consideration of numerous stakeholders and in conjunction with a careful evaluation of long-term and potential unintended consequences.

Development of Organ-Specific Donor Risk Indices

Akkina, Sanjeev K.; Asrani, Sumeet K.; Peng, Yi; Stock, Peter; Kim, Ray; Israni, Ajay K.

2012-01-01

Due to the shortage of deceased donor organs, transplant centers accept organs from marginal deceased donors, including older donors. Organ-specific donor risk indices have been developed to predict graft survival using various combinations of donor and recipient characteristics. We will review the kidney donor risk index (KDRI) and liver donor risk index (LDRI) and compare and contrast their strengths, limitations, and potential uses. The Kidney Donor Risk Index has a potential role in developing new kidney allocation algorithms. The Liver Donor Risk Index allows for greater appreciation of the importance of donor factors, particularly for hepatitis C-positive recipients; as the donor risk index increases, rates of allograft and patient survival among these recipients decrease disproportionately. Use of livers with high donor risk index is associated with increased hospital costs independent of recipient risk factors, and transplanting livers with high donor risk index into patients with Model for End-Stage Liver Disease scores < 15 is associated with lower allograft survival; use of the Liver Donor Risk Index has limited this practice. Significant regional variation in donor quality, as measured by the Liver Donor Risk Index, remains in the United States. We also review other potential indices for liver transplant, including donor-recipient matching and the retransplant donor risk index. While substantial progress has been made in developing donor risk indices to objectively assess donor variables that affect transplant outcomes, continued efforts are warranted to improve these indices to enhance organ allocation policies and optimize allograft survival.

Introduction: Despite continuous advances in transplant medicine, there is a persistent worldwide shortage of organs available for donation. There is a growing body of research that supports that optimal management of deceased organ donors in Intensive Care Unit can substantially increase the availability of organs for transplant and improve outcomes in transplant recipients. Methods: A systematic literature review was performed, comprising a comprehensive search of the PubMed database for relevant terms, as well as individual assessment of references included in large original investigations, and comprehensive society guidelines. Results: In addition to overall adherence to catastrophic brain injury guidelines, optimization of physiologic state in accordance with established donor management goals (DMGs), and establishment of system-wide processes for ensuring early referral to organ procurement organizations (OPOs), several specific critical care management strategies have been associated with improved rates and outcomes of renal transplantation from deceased donors. These include vasoactive medication selection, maintenance of euvolemia, avoidance of hydroxyethyl starch, glycemic control, targeted temperature management, and blood transfusions if indicated. Conclusions: Management of deceased organ donors should focus first on maintaining adequate perfusion to all organ systems through adherence to standard critical care guidelines, early referral to OPOs, and family support. Furthermore, several specific DMGs and strategies have been recently shown to improve both the rates and outcomes of organ transplantation. PMID:27555674

Global trends and challenges in deceased donor kidney allocation.

2017-06-01

Worldwide, the number of patients able to benefit from kidney transplantation is greatly restricted by the severe shortage of deceased donor organs. Allocation of this scarce resource is increasingly challenging and complex. Striking an acceptable balance between efficient use of (utility) and fair access to (equity) the limited supply of donated kidneys raises controversial but important debates at ethical, medical, and social levels. There is no international consensus on the recipient and donor factors that should be considered in the kidney allocation process. There is a general trend toward a reduction in the influence of human leukocyte antigen mismatch and an increase in the importance of other factors shown to affect posttransplant outcomes, such as cold ischemia, duration of dialysis, donor and recipient age, and comorbidity. Increased consideration of equity has led to improved access to transplantation for disadvantaged patient groups. There has been an overall improvement in the transparency and accountability of allocation policies. Novel and contentious approaches in kidney allocation include the use of survival prediction scores as a criterion for accessing the waiting list and at the point of organ offering with matching of predicted graft and recipient survival. This review compares the diverse international approaches to deceased donor kidney allocation and their evolution over the last decade. Copyright © 2017 International Society of Nephrology.

Background: The Kidney Foundation of Canada developed a pilot campaign to educate persons attending junior hockey league games in London, Ontario, Canada, on deceased organ donation. Objective: To evaluate the impact of a hockey campaign on the number of new organ and tissue donor registrants. Design: Population-based retrospective cohort study. Setting: Residents of London, Ontario. Patients: We included 255 476 individuals eligible to register for organ donation with a London, Ontario postal code. Measurements: We compared the number of new deceased organ donor registrants in London, Ontario, during the campaign period (March 12 to April 16, 2015) with 3 different time periods (December 30, 2014 to February 3, 2015; February 4 to March 11, 2015; April 17 to May 22, 2015). We also compared registration rates in London with 2 Ontario cities (Kitchener-Waterloo and Hamilton) matching in a 1:1 ratio on age, sex, and income quintile. Methods: To compare registrations across time periods, we used binomial regression with an identity link function and generalized estimating equations with an independence correlation structure. We used modified Poisson regression to compare registration rates between cities. Results: During the campaign period, there were slightly more registrations (1218 registered of 252 832 unregistered individuals [0.48%]) compared with an earlier time period (risk difference: 0.09%; 95% confidence interval [CI]: 0.05%-0.12%). However, there was no significant difference compared with 2 time periods immediately before and after the campaign. London had slightly more registrations during the campaign period compared with the matched city of Hamilton (1180 registered of 236 582 unregistered individuals [0.50%] vs 490 registered of 236 582 unregistered individuals [0.21%]; risk ratio: 2.41; 95% CI: 2.17-2.68). The registration rate in London did not significantly differ from Kitchener-Waterloo. Limitations: Unable to conclude whether the minor increase in deceased organ donor registration was the result of the campaign or other factors (e.g., simultaneous organ registration events, seasonality). Conclusions: Overall, a minor increase in deceased organ donor registration was observed during the hockey organ donation awareness campaign; however, the specific impact of the campaign on organ donor registration could not be determined.

Little is known about the effect of education programs on changing attitudes and behaviors of participants and their families toward deceased organ donation. The subjects of this randomized trial were Japanese nursing students who were not previously designated organ donors. They were randomly assigned to either the education program or information booklet group. The program comprised a lecture followed by group discussion and information booklet. The primary outcome was self-reported organ donor designation. Outcomes were assessed by questionnaire. Data of 203 (99.0%) students were analyzed. At study end, seven of 102 students (6.9%) of the program group and one of 101 students (1.0%) of the booklet group consented to donate organs (proportion ratio 6.93 [95% CI 0.87-55.32]). There were significant between-group differences in willingness to consent for donation (54.9% vs 39.6%; proportion ratio 1.39 [95% CI 1.03-1.87]), family discussion (31.4% vs 15.9%; 1.98 [1.16-3.38]), and organ donor designation of family members (11.8% vs 2.0%; 5.94 [1.36-25.88]). No group differences were found in willingness for organ donation by students and family members. Although there were no significant between-group differences in organ donor designation, the program seems to indirectly promote consent to organ donation by their families. © 2016 The Authors.

Kidney transplantation has become more resource intensive as recipient complexity has increased and average donor quality has diminished over time. A national retrospective cohort study was performed to assess the impact of kidney donor and recipient characteristics on transplant center cost (exclusive of organ acquisition) and Medicare reimbursement. Data from the national transplant registry, University HealthSystem Consortium hospital costs, and Medicare payments for deceased donor (N=53,862) and living donor (N=36,715) transplants from 2002–2013 were linked and analyzed using multivariate linear regression modeling. Deceased donor kidney transplant costs were correlated with recipient (Expected Post Transplant Survival Score, degree of allosensitization, obesity, cause of renal failure) donor (age, cause of death, donation after cardiac death, terminal creatinine), and transplant (histocompatibility matching) characteristics. Living donor costs rose sharply with higher degrees of allosensitization, and were also associated with obesity, cause of renal failure, recipient work ability, and 0-ABDR mismatching. Analysis of Medicare payments for a subsample of 24,809 transplants demonstrated minimal correlation with patient and donor characteristics. In conclusion, the complexity in the landscape of kidney transplantation increases center costs, posing financial disincentives that may reduce organ utilization and limit access for higher risk populations.

According to the Indian chronic kidney disease registry, in 2010 only 2% of end stage kidney disease patients were managed with kidney transplantation, 37% were managed with dialysis and 61% were treated conservatively without renal replacement therapy. In countries like India, where a well-organized deceased donor kidney transplantation program is not available, living donor kidney transplantation is the major source of organs for kidney transplantation. The most common reason to decline a donor for directed living donation is ABO incompatibility, which eliminates up to one third of the potential living donor pool. Because access to transplantation with human leukocyte antigen (HLA)-desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end stage kidney disease patients. KPD is a rapidly growing and cost-effective living donor kidney transplantation strategy for patients who are incompatible with their healthy, willing living donor. In principle, KPD is feasible for any centre that performs living donor kidney transplantation. In transplant centres with a large living donor kidney transplantation program KPD does not require extra infrastructure, decreases waiting time, avoids transplant tourism and prevents commercial trafficking. Although KPD is still underutilized in India, it has been performed more frequently in recent times. To substantially increase donor pool and transplant rates, transplant centres should work together towards a national KPD program and frame a uniform acceptable allocation policy. © 2014 Asian Pacific Society of Nephrology.

Rhabdomyolysis in deceased donors usually causes acute renal failure (ARF), which may be considered a contraindication for kidney transplantation. From January 2012 to December 2016, 30 kidneys from 15 deceased donors with severe rhabdomyolysis and ARF were accepted for transplantation at our center. The peak serum creatinine (SCr) kinase, myoglobin, and SCr of the these donors were 15 569±8597 U/L, 37 092±42 100 μg/L, and 422±167 μmol/L, respectively. Two donors received continuous renal replacement therapy due to anuria. Six kidneys exhibited a discolored appearance (from brown to glossy black) due to myoglobin casts. The kidney transplant results from the donors with rhabdomyolysis donors were compared with those of 90 renal grafts from standard criteria donors (SCD). The estimated glomerular filtration rate at 2 years was similar between kidney transplants from donors with rhabdomyolysis and SCD (70.3±14.6 mL/min/1.73 m 2 vs 72.3±15.1 mL/min/1.73 m 2 ). We conclude that excellent graft function can be achieved from kidneys donors with ARF caused by rhabdomyolysis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Development of organ-specific donor risk indices.

2012-04-01

Because of the shortage of deceased donor organs, transplant centers accept organs from marginal deceased donors, including older donors. Organ-specific donor risk indices have been developed to predict graft survival with various combinations of donor and recipient characteristics. Here we review the kidney donor risk index (KDRI) and the liver donor risk index (LDRI) and compare and contrast their strengths, limitations, and potential uses. The KDRI has a potential role in developing new kidney allocation algorithms. The LDRI allows a greater appreciation of the importance of donor factors, particularly for hepatitis C virus-positive recipients; as the donor risk index increases, the rates of allograft and patient survival among these recipients decrease disproportionately. The use of livers with high donor risk indices is associated with increased hospital costs that are independent of recipient risk factors, and the transplantation of livers with high donor risk indices into patients with Model for End-Stage Liver Disease scores < 15 is associated with lower allograft survival; the use of the LDRI has limited this practice. Significant regional variations in donor quality, as measured by the LDRI, remain in the United States. We also review other potential indices for liver transplantation, including donor-recipient matching and the retransplant donor risk index. Although substantial progress has been made in developing donor risk indices to objectively assess donor variables that affect transplant outcomes, continued efforts are warranted to improve these indices to enhance organ allocation policies and optimize allograft survival.

2017-06-01

Optimum use of donor organs can increase the reach of the transplantation therapy to more patients on waiting list. The heart transplantation (HTx) has remained stagnant in United States over the past decade at approximately 2,500 HTx annually. With the use of the United Network of Organ Sharing (UNOS) deceased donor database (DCD) we aimed to evaluate donor factors predicting donor heart utilization. UNOS DCD was queried from 2005 to 2014 to identify total number of donors who had at least one of their organs donated. We then generated a multivariate logistic regression model using various demographic and clinical donor factors to predict donor heart use for HTx. Donor hearts not recovered due to consent or family issues or recovered for nontransplantation reasons were excluded from the analysis. During the study period there were 80,782 donors of which 23,606 (29%) were used for HTx, and 38,877 transplants (48%) were not used after obtaining consent because of poor organ function (37%), donor medical history (13%), and organ refused by all programs (5%). Of all, 22,791 donors with complete data were used for logistic regression (13,389 HTx, 9,402 no-HTx) which showed significant predictors of donor heart use for HTx. From this model we assigned probability of donor heart use and identified 3,070 donors with HTx-eligible unused hearts for reasons of poor organ function (28%), organ refused by all programs (15%), and recipient not located (9%). An objective system based on donor factors can predict donor heart use for HTx and may help increase availability of hearts for transplantation from existing donor pool.

The roles of dominos and nonsimultaneous chains in kidney paired donation.

PubMed

Gentry, S E; Montgomery, R A; Swihart, B J; Segev, D L

2009-06-01

Efforts to expand kidney paired donation have included matching nondirected donors (NDDs) to incompatible pairs. In domino paired donation (DPD), an NDD gives to the recipient of an incompatible pair, beginning a string of simultaneous transplants that ends with a living donor giving to a recipient on the deceased donor waitlist. Recently, nonsimultaneous extended altruistic donor (NEAD) chains were introduced. In a NEAD chain, the last donor of the string of transplants initiated by an NDD is reserved to donate at a later time. Our aim was to project the impact of each of these strategies over 2 years of operation for paired donation programs that also allocate a given number of NDDs. Each NDD facilitated an average of 1.99 transplants using DPD versus 1.90 transplants using NEAD chains (p = 0.3), or 1.0 transplants donating directly to the waitlist (p < 0.001). NEAD chains did not yield more transplants compared with simultaneous DPD. Both DPD and NEAD chains relax reciprocality requirements and rebalance the blood-type distribution of donors. Because traditional paired donation will leave many incompatible pairs unmatched, novel approaches like DPD and NEAD chains must be explored if paired donation programs are to help a greater number of people.

Prostate cancer is the second most common malignant tumor (13%) among male subjects in Poland. The aim of this study was to assess the prevalence of prostate cancer in a group of deceased liver donors. A total of 784 liver procurement attempts from deceased donors were performed in the Department of General, Transplant and Liver Surgery, Medical University of Warsaw, from January 1, 2012, to April 1, 2015; 700 grafts were actually used in a liver transplant. A retrospective analysis was performed based on these data. Among male donors (n = 486 [62%]), there were 30 (6.2%) cases of a frozen biopsy of the prostate performed before making the decision regarding liver graft utilization. In the group of 30 donors who underwent prostate examination, 3 (10%) were diagnosed as having prostate cancer of a moderate invasive stage. In 2 other cases, fresh frozen section suggested prostate cancer; however, this fact was not confirmed in routine section. liver transplantation was not performed in these cases of suspicion of prostate cancer (5 of 30 [17%]) in the frozen biopsy specimens. The difference between groups of donors with prostate cancer and benign pathology of the prostate gland according to prostate-specific antigen serum concentration (P = .578) or age (P = .730) was not statistically significant. Increased prostate-specific antigen serum concentrations without a diagnosis of prostate cancer in histopathologic examinations should not be an independent contraindication for performing organ transplantation. Nevertheless, for recipient safety, even when prostate cancer is only suspected in the frozen biopsy sample, the procured organ should not be used for transplantation. Copyright © 2016 Elsevier Inc.

Patients after liver transplant have a high incidence of chronic kidney disease and end-stage renal disease (ESRD). We investigated kidney transplantation after liver transplantation using the Organ Procurement Transplant Network database. The Organ Procurement Transplant Network database was queried for patients who received kidney transplantation after previous liver transplantation. These patients were compared with patients who received primary kidney transplantation alone during the same time period. Between 1997 and 2008, 157,086 primary kidney transplants were performed. Of these, 680 deceased donor kidney transplants and 410 living donor kidney transplants were performed in previous recipients of liver transplants. The number of kidney after liver transplants performed each year has increased from 37 per year to 124 per year in 2008. The time from liver transplant to kidney transplant increased from 8.2 to 9.0 years for living donor transplants and from 5.4 to 9.6 years for deceased donor. The 1, 3, and 5 year actuarial graft survival in both living donor kidney after liver transplant and deceased donor kidney after liver transplant are less than the kidney transplant alone patients. However, the death-censored graft survivals are equal. The patient survival is also less but is similar to what would be expected in liver transplant recipients who did not have ESRD. In 2008, kidney after liver transplantation represented 0.9% of the total kidney alone transplants performed in the United States. Kidney transplantation is an appropriate therapy for selected patients who develop ESRD after liver transplantation.

African Americans with lupus who receive kidney transplants have high prevalence of predictors of allograft failure, which can explain their poor outcomes. Of 1223 African Americans and 1029 Caucasian Americans with lupus who received kidney transplants from deceased donors between 1987 and 2006 with complete records in the UNOS program, 741 pairs were matched in 16 predictors employing a predicted probability of group membership. The primary outcome was allograft failure. Main secondary outcomes were rejection, allograft failure due to rejection, and mortality. Matched pairs were predominantly women (82%) with a mean age of 39 years. Twenty-four percent of recipients received kidneys from expanded criteria donors. African Americans and Caucasian Americans matched well (p ≥ 0.05): donor age, gender and race; recipient age, gender, education and insurance; dialysis prior to transplant, kidneys from expanded criteria donors, cold ischemia time, history of prior kidney transplant, panel reactive antibodies, human leukocyte antigens mismatch, blood type compatibility, transplant Era, and follow-up time. Contrary to the unmatched cohort with significantly higher allograft failure rate (events per 100 patient-years) in African Americans compared to Caucasian Americans (10.49 vs 6.18, p<0.001), matched pairs had similar allograft failure rates (8.41 vs 7.81, p=0.418). Matched pairs also had similar rates of rejections (9.82 vs 9.39, p=0.602), allograft failure due to rejection (6.19 vs 5.71, p=0.453), and mortality (2.79 vs 3.52, p=0.097). In lupus recipients of kidney transplants from deceased donors, African American and Caucasian Americans have similar allograft failure rates when predictors are matched between groups.

Pediatric liver transplantation is limited by donation. In the last 5 years, urgent conditions have forced transplant teams to accept donors with minor suboptimal conditions, termed "extended donor criteria." Among those, the risk of using severe hypernatremic donors (SHD) for liver transplant is not yet well established. The aim of this study is to report the outcome of pediatric patients receiving grafts from SHD. Clinical records of patients transplanted in the last 3 years at Hospital Luis Calvo Mackenna, Santiago, Chile, were reviewed. Outcome was evaluated in terms of patient and graft survival and complications potentially associated to the donor condition. Five of 33 deceased donor transplants presented with SHD. All recipients were waiting transplant in an acute condition, one of them in acute liver failure (ALF). No living related donor was available. Donors' serum sodium was 169 to 193 mEq/L before medical management and between 157 and 172 mEq/L at procurement. One patient died from sepsis related to biliary complications, and the patient suffering ALF developed primary graft nonfunction, received a second transplant 2 weeks later, and recovered to stable medical condition. No other complication was registered in these patients. Our findings allow us to postulate that hypernatremic deceased donors may be used for pediatric liver transplant under special circumstances.

Nucleic acid testing (NAT) has reduced the risk of transmitting infectious disease through blood transfusion. Currently NAT for HIV-1 and HCV are FDA licensed and performed by nearly all blood collection facilities, but HBV NAT is performed under an investigational study protocol. Residual risk estimates indicate that NAT could potentially reduce disease transmission through transplanted tissue. However, tissue donor samples obtained post-mortem have the potential to produce an invalid NAT result due to inhibition of amplification reactions by hemolysis and other factors. The studies reported here summarize the development of protocols to allow NAT of deceased donor samples with reduced rates of invalid results. Using these protocols, inventories from two tissue centers were tested with greater than 99% of samples producing a valid test result.

There are three categories of deceased donors of kidney transplantation in China, donation after brain death (DBD), donation after circulatory death (DCD), and donation after brain death followed by circulatory death (DBCD) donors. The aim of this study was to compare the outcomes of kidney transplantation from these three categories of deceased donors. We retrospectively reviewed 469 recipients who received deceased kidney transplantation in our hospital from February 2007 to June 2015. The recipients were divided into three groups according to the source of their donor kidneys: DBD, DCD, or DBCD. The primary endpoints were delayed graft function (DGF), graft loss, and patient death. The warm ischemia time was much longer in DCD group compared to DBCD group (18.4 minutes vs 12.9 minutes, P < .001). DGF rate was higher in DCD group than in DBD and DBCD groups (22.5% vs 10.2% and 13.8%, respectively, P = .021). Urinary leakage was much higher in DCD group (P = .049). Kaplan-Meier analysis showed that 1-, 2-, and 3-year patient survivals were all comparable among the three groups. DBCD kidney transplantation has lower incidences of DGF and urinary leakage than DCD kidney transplant. However, the overall patient and graft survival were comparable among DBD, DCD, and DBCD kidney transplantation. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

2015-09-01

Solid organ transplantation as a treatment for end stage organ failure has been an accepted treatment option for decades. Despite advances in medicine and technology, and increased awareness of organ donation and transplantation, the gap between supply and demand continues to widen. Living donation has been an option that has increased the number of transplants despite the continued shortage of deceased organs. In the early 2000s live donor transplantation reached an all-time high in the United States. As a result, a consensus meeting was convened in 2000 to increase the oversight of living donor transplantation. Both the Centers for Medicare and Medicaid Services and the United Network for Organ Sharing developed regulations that transplant programs performing live donor transplantation. These regulations and guidelines involve the education, evaluation, informed consent process and living donor follow-up care. Two areas in which had significant changes included the psychosocial and the independent living donor advocate (ILDA) evaluation. The purpose of this paper was to outline the current regulations and guidelines associated with the psychosocial and ILDA evaluation as well as provide further recommendations for the administration of a high quality evaluation of living donors. The goals and timing of the evaluation and education of donors; qualifications of the health care providers performing the evaluation; components of the evaluation; education provided to donors; documentation of the evaluation; participation in the selection committee meeting; post-decline and post-donation care of donors is described. Caveats including the paired donor exchange programs and non-directed and directed donation are also considered.

A simple bedside approach to therapeutic goals achievement during the management of deceased organ donors--An adapted version of the "VIP" approach.

The disproportion between the supply and demand of transplant organs could be alleviated by improving the quality of clinical management of deceased potential donors. As a large number of donor losses by cardiac arrest occur due to hemodynamic instability, without instituting all essential maintenance measures, it is likely that the application of simplified potential donor maintenance protocols will help to decrease potential donor losses and increase the supply of organs for transplantation. The Ventilation, Infusion and Pumping (VIP) strategy is a mnemonic method that brings together key aspects of the restoration of oxygen delivery to tissues during hemodynamic instability: adequate mechanical Ventilation, volume Infusion and evaluation of heart Pump effectiveness. The inclusion of the additional initials, "P" and "S," refers to Pharmacological treatment and Specificities involved in the etiology of shock. The use of simplified care standards can assist in adhering to essential potential donor management measures. Therefore, using a simplified method as the adapted VIP approach can contribute to improving management standards of potential organ donors and increasing the supply of organs for transplantation. © 2015 John Wiley & Sons A/S.

The policies of organ transplantation in Europe: issues and problems.

PubMed

Defever, M

1990-11-01

Transplantation has evolved from an experiment to a routinely performed procedure for a widening range of organs. Transplantation in Europe is dominated by the scarcity of organs from deceased donors leading to problems of selection criteria for recipients, of legal protection for donors and of the empowerment of agencies for allocative decisions. Although public involvement is very emotional, there has been a benign neglect in several European countries by policy makers, accepting implicitly organ transplantation leading to a variety of programs for diffusion, organization, and financing of transplantation. Non-transplanting hospitals play a key role in organ procurement and transplant centers are increasingly subject to quality assessment, whereby the issue of the relation between improved outcome at higher volumes comes to the forefront. International cooperation is critical for the development of effective transplant programs in Europe.

Effect of media presentations on willingness to commit to organ donation.

We examine how presentations of organ donation cases in the media may affect people's willingness to sign organ donation commitment cards, donate the organs of a deceased relative, support the transition to an "opt-out" policy, or donate a kidney while alive. We found that providing identifying information about the prospective recipient (whose life was saved by the donation) increased the participants' willingness to commit to organ donation themselves, donate the organs of a deceased relative, or support a transition to an "opt-out" policy. Conversely, identifying the deceased donor tended to induce thoughts of death rather than about saving lives, resulting in fewer participants willing to donate organs or support measures that facilitated organ donation. A study of online news revealed that identification of the donor is significantly more common than identification of the recipient in the coverage of organ donation cases-with possibly adverse effects on the incidence of organ donations.

Organ donation and Islam-challenges and opportunities.

Sharif, Adnan

2012-09-15

The issue of organ donation in Islam has been debated for decades, with most religious authorities sanctioning both living-organ and deceased-organ donation. However, disquiet among the Islamic community on the compatibility of organ donation with their faith remains, especially in relation to deceased-organ donation. This remains a topical, controversial, and challenging component of organ procurement at both local and international levels. In this article, I will explore Islamic arguments both for and against organ donation, in the context of both living-donor and deceased-donor models. By discussing both practical and philosophical perspectives, the aim is to facilitate discussion on how best to achieve consensus on this issue by driving the debate forward in an open and all-encompassing manner. Although every attempt should be made to achieve consensus among key Muslim opinion makers (individuals, authorities, and institutions), encouraging personalized decision making by intellectual effort should be the goal to achieve genuine informed consent.

Background and objectives Data reported to the Organ Procurement and Transplantation Network (OPTN) are used in kidney transplant research, policy development, and assessment of center quality, but the accuracy of early post–transplant outcome measures is unknown. Design, setting, participants, & measurements The Deceased Donor Study (DDS) is a prospective cohort study at five transplant centers. Research coordinators manually abstracted data from electronic records for 557 adults who underwent deceased donor kidney transplantation between April of 2010 and November of 2013. We compared the post-transplant outcomes of delayed graft function (DGF; defined as dialysis in the first post–transplant week), acute rejection, and post–transplant serum creatinine reported to the OPTN with data collected for the DDS. Results Median kidney donor risk index was 1.22 (interquartile range [IQR], 0.97–1.53). Median recipient age was 55 (IQR, 46–63) years old, 63% were men, and 47% were black; 93% had received dialysis before transplant. Using DDS data as the gold standard, we found that pretransplant dialysis was not reported to the OPTN in only 11 (2%) instances. DGF in OPTN data had a sensitivity of 89% (95% confidence interval [95% CI], 84% to 93%) and specificity of 98% (95% CI, 96% to 99%). Surprisingly, the OPTN data accurately identified acute allograft rejection in only 20 of 47 instances (n=488; sensitivity of 43%; 95% CI, 17% to 73%). Across participating centers, sensitivity of acute rejection varied widely from 23% to 100%, whereas specificity was uniformly high (92%–100%). Six-month serum creatinine values in DDS and OPTN data had high concordance (n=490; Lin concordance correlation =0.90; 95% CI, 0.88 to 0.92). Conclusions OPTN outcomes for recipients of deceased donor kidney transplants have high validity for DGF and 6-month allograft function but lack sensitivity in detecting rejection. Future studies using OPTN data may consider focusing on allograft function at 6 months as a useful outcome. PMID:26668026

Summary Background and objectives Hispanic patients undergoing chronic dialysis are less likely to receive a kidney transplant compared with non-Hispanic whites. This study sought to elucidate disparities in the path to receipt of a deceased donor transplant between Hispanic and non-Hispanic whites. Design, setting, participants, & measurements Using the US Renal Data System, 417,801 Caucasians who initiated dialysis between January 1, 1995 and December 31, 2007 with follow-up through 2008 were identified. This study investigated time from first dialysis to first kidney transplantation, time from first dialysis to waitlisting, and time from waitlisting to kidney transplantation. Multivariable Cox regression estimated cause-specific hazard ratios (HRCS) and subdistribution (competing risk) hazard ratios (HRSD) for Hispanics versus non-Hispanic whites. Results Hispanics experienced lower adjusted rates of deceased donor kidney transplantation than non-Hispanic whites (HRCS, 0.77; 95% confidence interval [95% CI], 0.75 to 0.80) measured from dialysis initiation. No meaningful differences were found in time from dialysis initiation to placement on the transplant waitlist. Once waitlisted, Hispanics had lower adjusted rates of deceased donor kidney transplantation (HRCS, 0.66; 95% CI, 0.64 to 0.68), and the association attenuated once accounting for competing risks (HRSD, 0.79; 95% CI, 0.77 to 0.81). Additionally controlling for blood type and organ procurement organization further reduced the disparity (HRSD, 0.99; 95% CI, 0.96 to 1.02). Conclusions After accounting for geographic location and controlling for competing risks (e.g., Hispanic survival advantage), the disparity in access to deceased donor transplantation was markedly attenuated among Hispanics compared with non-Hispanic whites. To overcome the geographic disparities that Hispanics encounter in the path to transplantation, organ allocation policy revisions are needed to improve donor organ equity. PMID:24115195

Anti-T-lymphocyte globulins (ATG) are most commonly used as induction agents in kidney transplantation (KT). In this study, we investigated the use of ATG as induction therapy in deceased-donor KT. Among 152 deceased-donor KT recipients transplanted between January 2009 and December 2003, 147 with exact data were enrolled in this study. Delayed graft function was defined as dialysis requirement after KT. Greater than 10% panel-reactive antibody (PRA) was considered as positive. Total ATG (rATG-Fresenius) dosage and induction duration was evaluated. Mean age was 45 ± 10 years; 91 patients were male and 56 patients were female. Class I and class II PRA-positive patient numbers were 20 (13.6%) and 17 (11.5%), respectively. Pre-transplant dialysis vintage was 108 ± 63 months. Mean donor age was 42 ± 17, and cold ischemia time was 16 ± 5 hours. Eighty-nine patients (60%) had delayed graft function and needed at least one session of hemodialysis after transplantation. Cumulative ATG-F dosage was 676 ± 274 mg. The mean ATG-F cumulative dosage was 10.6 ± 3.8 mg/kg. At the end of first year, mean creatinine and proteinuria levels were 1.4 ± 1.0 mg/dL and 0.3 ± 0.4 g/d, respectively. Mean follow-up time was 32 ± 20 months. During follow-up, there were 14 graft failures and 11 patients died. Patient survival for 1 and 2 years were 93% and 92.3%, respectively. Death-censored graft survival rates for 1 and 2 years were 94.8% and 90.8%, respectively. ATG-F induction provides acceptable graft and patient survival in deceased-donor KT. ATG-F infusion is well tolerated. Infection rates seem to be acceptable compared with all transplantation populations. Copyright © 2017 Elsevier Inc. All rights reserved.

Interventional radiology has acquired a key role in every liver transplantation (LT) program by treating the majority of vascular and non-vascular post-transplant complications, improving graft and patient survival and avoiding, in the majority of cases, surgical revision and/or re-transplantation. The aim of this paper is to review indications, technical consideration, results achievable and potential complications of interventional radiology procedures after deceased donor LT and living related adult LT.

2008-01-01

The pros and cons of a regulated system of financial incentives for living donors are being actively debated. To date, a detailed proposal on how such a system could work has not been developed. Herein, the specifics of a potential model, using the infrastructure already in place for deceased donor evaluation and allocation, are outlined.

Incentivizing deceased organ donation: a Swedish priority-setting perspective.

The established deceased organ donation models in many countries, relying chiefly on altruism, have failed to motivate a sufficient number of donors. As a consequence organs that could save lives are routinely missed leading to a growing gap between demand and supply. The aim of this paper is twofold; firstly to develop a proposal for compensated deceased organ donation that could potentially address the organ shortage; secondly to examine the compatibility of the proposal with the ethical values of the Swedish healthcare system. The proposal for compensating deceased donation is grounded in behavioural agency theory and combines extrinsic, intrinsic and signalling incentives in order to increase prosocial behaviour. Furthermore the compatibility of our proposal with the values of the Swedish healthcare system is evaluated in reference to the principles of human dignity, needs and solidarity, and cost effectiveness. Extrinsic incentives in the form of a 5,000 compensation towards funeral expenses paid to the estate of the deceased or family is proposed. Intrinsic and signalling incentives are incorporated by allowing all or part of the compensation to be diverted as a donation to a reputable charity. The decision for organ donation must not be against the explicit will of the donor. We find that our proposal for compensated deceased donation is compatible with the values of the Swedish healthcare system, and therefore merits serious consideration. It is however important to acknowledge issues relating to coercion, commodification and loss of public trust and the ethical challenges that they might pose.

The Renal and Lung Living Donors Evaluation Study (RELIVE) assesses outcomes of live lung (lobectomy) donors. This is a retrospective cohort study at University of Southern California (USC) and Washington University (WASHU) Medical Centers (1993–2006), using medical records to assess morbidity and national databases to ascertain post-donation survival and lung transplantation. Serious complications were those requiring significant treatment, potentially life-threatening, or leading to prolonged hospitalization. The 369 live lung donors (287 USC, 82 WASHU) were predominantly white, non-Hispanic, and male; 72% had a biological relationship to the recipient, and 30% were recipient parents. Serious complications occurred in 18% of donors; 2.2% underwent reoperation, and 6.5% had an early rehospitalization. The two centers had significantly different incidences of serious complications (p<0.001). No deaths occurred and no donors underwent lung transplantation during 4,000+ person-years of follow-up (death: minimum 4, maximum 17 years; transplant: minimum 5, maximum 19). Live lung donation remains a potential option for recipients when using deceased donor lungs lacks feasibility. However, the use of two live donors for each recipient and the risk of morbidity associated with live lung donation do not justify this approach when deceased lung donors remain available. Center effects and long-term outcomes require further evaluation. PMID:25039865

Cost-effectiveness of using kidneys from Hepatitis C nucleic acid test positive donors for transplantation in Hepatitis C negative recipients.

Kidneys from deceased donors that are hepatitis C (HCV) nucleic acid test (NAT) positive are infrequently used for transplantation in HCV negative patients due to concerns of disease transmission. With the development of direct acting antivirals (DAA's) for HCV, there is now potential to use these kidneys in HCV negative candidates. However, the high cost of DAAs poses a challenge to adoption of this strategy. We created a Markov model to examine the cost-effectiveness of using deceased donors infected with HCV for kidney transplantation in uninfected waitlist candidates. In the primary analysis this strategy was cost saving and improved health outcomes compared to remaining on the waitlist for an additional two or more years to receive a HCV negative transplant. The strategy was also cost-effective with an incremental cost-effectiveness ratio of $56018 per quality adjusted life year (QALY) from the payer perspective, and $4647 per QALY from the societal perspective, compared to remaining on the waitlist for one additional year. The results were consistent in one way and probabilistic sensitivity analyses. We conclude that the use of kidneys from deceased donors with HCV infection are likely to lead to improved clinical outcomes at reduced cost for HCV negative transplant candidates.

This study was conducted to determine effect of lower measured hepatic arterial (HA) flow (<400 mL/min) on biliary complications and graft survival after deceased donor liver transplantation. Hepatic artery is the main blood supply to bile duct and lack of adequate HA flow is thought to be a risk factor for biliary complications. A retrospective review of 1300 patients who underwent deceased donor liver transplantation was performed. Patients with arterial complications were excluded to eliminate potential contribution to biliary complications from HA thrombosis. Patients were divided into low (<400 mL/min; N = 201) and high (≥400 mL/min; N = 1099) HA flow groups. Incidence of biliary complications and graft survival were analyzed. HA flows less than 400 mL/min were associated with increased rate of biliary strictures in younger donors (<50 years old), and in patients with duct-to-duct anastomoses (P = 0.028). Lower HA flows were associated with decreased graft survival (P = 0.013). Donor older than 50 years was associated with increased rate of biliary strictures (hazard ratio [HR], 1.67; 95% confidence interval [CI], 1.14-2.45; P = 0.0085) and graft failure (HR, 1.68; 95% CI, 1.35-2.1; P <0.0001) on multivariate analyses. HA flow less than 400 mL/min was associated with biliary strictures (HR, 1.53; 95% CI, 1.04-2.24; P = 0.0297) on univariate analysis only. HA flow less than 400 mL/min was associated with higher rate of biliary strictures in younger donors with duct-to-duct reconstruction and lower graft survival. A consideration should be given to increase the intraoperative HA flow to prevent biliary strictures in such patients.

Background: Shortfalls in deceased organ donation lead to shortages of solid organs available for transplantation. We assessed rates of deceased organ donation and compared hospitals that had clinical services for transplant recipients (transplant hospitals) to those that did not (general hospitals). Methods: We conducted a population-based cohort analysis involving patients who died from traumatic brain injury, subarachnoid hemorrhage, intracerebral hemorrhage or other catastrophic neurologic conditions in Ontario, Canada, between Apr. 1, 1994, and Mar. 31, 2011. We distinguished between acute care hospitals with and without transplant services. The primary outcome was actual organ donation determined through the physician database for organ procurement procedures. Results: Overall, 87 129 patients died from catastrophic neurologic conditions during the study period, of whom 1930 became actual donors. Our primary analysis excluded patients from small hospitals, reducing the total to 79 746 patients, of whom 1898 became actual donors. Patients who died in transplant hospitals had a distribution of demographic characteristics similar to that of patients who died in other large general hospitals. Transplant hospitals had an actual donor rate per 100 deaths that was about 4 times the donor rate at large general hospitals (5.0 v. 1.4, p < 0.001). The relative reduction in donations at general hospitals was accentuated among older patients, persisted among patients who were the most eligible candidates and amounted to about 121 fewer actual donors per year (adjusted odds ratio 0.58, 95% confidence interval 0.36–0.92). Hospital volumes were only weakly correlated with actual organ donation rates. Interpretation: Optimizing organ donation requires greater attention to large general hospitals. These hospitals account for most of the potential donors and missed opportunities for deceased organ donation. PMID:23549970

Liver transplantation in the United Kingdom.

2016-08-01

Liver transplantation (LT) services in the United Kingdom are provided by 7 designated transplant centers for a population of approximately 64 million. The number of deceased organ donors has grown, and in 2014-2015 it was 1282 (570 donation after circulatory death and 772 donation after brain death). Donor risk is increasing. In 2014-2015, there were 829 LTs from deceased and 38 from living donors. The common causes for transplantation are liver cell cancer, viral hepatitis, and alcohol-related liver disease. Livers are allocated first nationally to super-urgent listed patients and then on a zonal basis. The United Kingdom will be moving toward a national allocation scheme. The median interval between listing and transplantation is 152 days for adults awaiting their first elective transplant. Of the adults listed for the first elective transplant, 68% underwent transplantation at < 1 year; 17% are waiting; and 4% and 11% were removed or died, respectively. The 1- and 5-year adult patient survival rate from listing is 81% and 68%, respectively, and from transplantation is 92% and 80%, respectively. The transplant program is funded through general taxation and is free at the point of care to those who are eligible for National Health Service (NHS) treatment; some have to pay for medication (up to a maximum payment of US $151/year). The competent authority is the Human Tissue Authority which licenses donor characterization, retrieval, and implantation; transplant units are commissioned by NHS England and NHS Scotland. National Health Service Blood and Transplant (NHSBT) promotes organ donation, maintains the organ donor register, obtains consent, and undertakes donor characterization and offering. NHSBT also maintains the national waiting list, develops and applies selection and allocation policies, monitors outcomes, and maintains the UK National Transplant Registry and commissions a national organ retrieval service.

Travel to procure deceased donor organs is associated with risk to transplant personnel. In many instances, multiple teams are present for a given operation. We studied our statewide experience to determine how much excess travel this redundancy entails, and generated alternate models for organ recovery. We reviewed our organ procurement organization’s experience with deceased donor operations between 2002 and 2008. Travel was expressed as cumulative person-miles between procurement team origin and donor hospital. A model of minimal travel was created, using thoracic and abdominal teams from the closest in-state center. A second model involved transporting donors to a dedicated procurement facility. Travel distance was recalculated using these models, and mode and cost of travel extrapolated from current practices. In 654 thoracic and 1469 abdominal donors studied, mean travel for thoracic teams was 1066 person-miles, and for abdominal teams was 550 person-miles. The mean distance traveled by thoracic and abdominal organs was 223 miles and 142 miles, respectively. Both hypothetical models showed reductions in team travel and reliance on air transport, with favorable costs and organ transport times compared to historical data. In summary, we found significant inefficiency in current practice, which may be alleviated using new paradigms for donor procurement. PMID:19656129

Since the beginning of the technology, there has been active debate about the role of human leucocyte antigen (HLA) matching in kidney allograft survival. Recent studies have reported diminishing importance of HLA matching, which have, in turn, been challenged by reports that suggest the continuing importance of these loci. Given the controversies, we examined the effect of HLA compatibility on kidney allograft survival by studying all first adult kidney transplants in the United States from a deceased donor. Using the United Network for Organ Sharing data, we identified first deceased donor kidney transplants between October 1, 1987, and December 31, 2013. Recipients were classified by their number of HLA mismatches. Cox multivariate regression analyses adjusting for recipient and donor transplant characteristics were performed to determine the impact of HLA compatibility on kidney allograft survival. Study cohort included 189 141 first adult kidney alone transplants, with a total of 994 558 years of kidney allograft follow-up time. Analyses adjusted for recipient and donor characteristics demonstrated a 13% higher risk (hazard ratio, 1.13; 95% confidence interval, 1.06-1.21) with 1 mismatch and a 64% higher risk (hazard ratio, 1.64, 95% confidence interval, 1.56-1.73) with 6 mismatches. Dividing the mismatch categories into 27 ordered permutations, and testing their 57 within mismatch category differences, demonstrated that all but 1 were equal, independent of locus. A significant linear relationship of hazard ratios was associated with HLA mismatch and affects allograft survival even during the recent periods of increasing success in renal transplantation.

Kidney and liver transplantation in the elderly.

Transplant surgery is facing a shortage of deceased donor organs. In response, the criteria for organ donation have been extended, and an increasing number of organs from older donors are being used. For recipients, the benefits of transplantation are great, and the growing ageing population has led to increasing numbers of elderly patients being accepted for transplantation. The literature was reviewed to investigate the impact of age of donors and recipients in abdominal organ transplantation, and to highlight aspects of the fine balance in donor and recipient selection and screening, as well as allocation policies fair to young and old alike. Overall, kidney and liver transplantation from older deceased donors have good outcomes, but are not as good as those from younger donors. Careful donor selection based on risk indices, and potentially biomarkers, special allocation schemes to match elderly donors with elderly recipients, and vigorous recipient selection, allows good outcomes with increasing age of both donors and recipients. The results of live kidney donation have been excellent for donor and recipient, and there is a trend towards inclusion of older donors. Future strategies, including personalized immunosuppression for older recipients as well as machine preservation and reconditioning of donor organs, are promising ways to improve the outcome of transplantation between older donors and older recipients. Kidney and liver transplantation in the elderly is a clinical reality. Outcomes are good, but can be optimized by using strategies that modify donor risk factors and recipient co-morbidities, and personalized approaches to organ allocation and immunosuppression. © 2015 BJS Society Ltd Published by John Wiley & Sons Ltd.

Living donor liver transplantation in India

PubMed Central

2016-01-01

Liver transplantation is currently in its golden period in India. The number of transplants being performed and the steady increase in the new programs that have emerged over the last decade is a testimony to it. The growth was not smooth, especially in the early years. But a multipronged approach in developing infrastructure and the involvement of multidisciplinary teams in the management of transplant patients has had a major positive impact on the outcome and as a result a positive impetus to the growth of this specialty in India. To date, the majority of transplants performed in India are live donor liver transplants. Deceased donation is more sporadic and concentrated in a couple of regions. With phenomenal increase in transplant activity in India, there is huge potential for streamlining data sharing among programs in India and with the rest of the world to ultimately benefit the transplant community.

2016-02-01

The clinical characteristics of all New England Organ Bank (NEOB) donors after circulatory death (DCD) donors were analyzed between July 1, 2009, and June 30, 2014. During that 5-year period, there were 494 authorized medically suitable potential DCDs that the NEOB evaluated, constituting more than 30% of deceased donors coordinated annually by the NEOB. From the cohort of 494 authorized potential DCDs, 331 (67%) became actual DCD, 82 (17%) were attempted as a DCD but did not progress to donation, and 81 (16%) transitioned to an actual donor after brain death (DBD). Two hundred seventy-six organs were transplanted from the 81 donors that transitioned from DCD to actual DBD, including 24 heart, 70 liver, 12 single and 14 bilateral lung, and 12 pancreas transplants. When patients with devastating brain injury admitted to the intensive care units are registered donors, the Organ Procurement Organization staff should share the patient's donation decision with the health care team and the patient's family, as early as possible after the comfort measures only discussion has been initiated. The experience of the NEOB becomes an important reference of the successful implementation of DCD that enables an expansion of deceased donation (inclusive of DBD).

Organ shortage is the major limitation for the growth of deceased donor liver transplant worldwide. One strategy to ameliorate this problem is to maximize the liver utilization rate. To assess predictors of liver utilization in Argentina. The national database was used to analyze transplant activity in 2010. Donor, recipient, and transplant variables were evaluated as predictors of graft utilization of number of rejected donor offers before grafting and with the occurrence of primary nonfunction (PNF) or early post-transplant mortality (EM). Of the 582 deceased donors, 293 (50.3%) were recovered for liver transplant. Variables associated with the nonrecovery of the liver were age ≥46 years, umbilical perimeter ≥92 cm, organ procurement outside Gran Buenos Aires, AST ≥42 U/l and ALT ≥29 U/l. The median number of rejected offers before grafting was 4, and in 71 patients (25%), there were ≥13. The only independent predictor for the occurrence of PNF (3.4%) or EM (5.2%) was the recipient's emergency status. During 2010 in Argentina, the liver was recovered in only half of donors. The low incidence of PNF and EM and the characteristics of the nonrecovered liver donors suggest that organ acceptance criteria should be less rigorous. © 2014 Steunstichting ESOT.

Kidney transplantation has become more resource intensive as recipient complexity has increased and average donor quality has diminished over time. A national retrospective cohort study was performed to assess the impact of kidney donor and recipient characteristics on transplant center cost (exclusive of organ acquisition) and Medicare reimbursement. Data from the national transplant registry, University HealthSystem Consortium hospital costs, and Medicare payments for deceased donor (N = 53 862) and living donor (N = 36 715) transplants from 2002 to 2013 were linked and analyzed using multivariate linear regression modeling. Deceased donor kidney transplant costs were correlated with recipient (Expected Post Transplant Survival Score, degree of allosensitization, obesity, cause of renal failure), donor (age, cause of death, donation after cardiac death, terminal creatinine), and transplant (histocompatibility matching) characteristics. Living donor costs rose sharply with higher degrees of allosensitization, and were also associated with obesity, cause of renal failure, recipient work status, and 0-ABDR mismatching. Analysis of Medicare payments for a subsample of 24 809 transplants demonstrated minimal correlation with patient and donor characteristics. In conclusion, the complexity in the landscape of kidney transplantation increases center costs, posing financial disincentives that may reduce organ utilization and limit access for higher-risk populations. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

Children as donors: a national study to assess procurement of organs and tissues in pediatric intensive care units.

A shortage of size-matched organs and tissues is the key factor limiting transplantation in children. Empirical data on procurement from pediatric donors is sparse. This study investigated donor identification, parental consent, and effectuation rates, as well as adherence to the national protocol. A national retrospective cohort study was conducted in all eight Dutch pediatric intensive care units. Records of deceased children were analyzed by an independent donation officer. Seventy-four (11%) of 683 deceased children were found to be suitable for organ donation and 132 (19%) for tissue donation. Sixty-two (84%) potential organ donors had been correctly identified; the parental consent and effectuation rate was 42%. Sixty-three (48%) potential tissue donors had been correctly identified; the parental consent and effectuation rate was 27%. Correct identification increased with age (logistic regression, organs: P = .024; tissues: P = .011). Although an overall identification rate of 84% of potential organ donors may seem acceptable, the variation observed suggests room for improvement, as does the overall low rate of identification of pediatric tissue donors. Efforts to address the shortage of organs and tissues for transplantation in children should focus on identifying potential donors and on the reasons why parents do not consent. © 2012 The Authors.

Background Allografts from living donors survive longer than those from deceased donors but the role of HLA mismatching in living kidney donation is still in question. We examined the effect of HLA compatibility on kidney allograft survival from living donors by studying all first adult kidney transplants performed in the United States over 25 years. Methods Using the United Network for Organ Sharing data, we identified first kidney transplants between October 1, 1987, and December 31, 2013. Recipients were classified by their number of HLA mismatches and stratified by donor origin. Cox multivariate regression analyses adjusting for recipient and donor transplant characteristics were performed to determine impact of HLA compatibility on kidney allograft survival for all living donors and for living related and living unrelated subsets. Results There were 66 596 first adult transplants from living donors with 348 960 years of follow-up. We found a linear relationship between HLA mismatch and allograft survival. In adjusted analyses, among all living donors, 1 mismatch conferred a 44% higher risk, whereas 6 mismatches conferred a twofold higher risk of allograft failure. When using 0-mismatched full siblings as a reference, living-donor kidneys reduce the hazard of failure by approximately 34% when compared with deceased donors. Twenty-five years of transplant experience, stratified by donor source, was summarized and presented as a guide for allocation. Conclusions These data reinforce the importance of optimizing HLA matching to further improve survival in first adult kidney allografts in the future, especially in living unrelated donations, when possible.

The Kidney Donor Profile Index (KDPI) has been introduced as an aid to evaluating deceased donor kidney offers, but the relative benefit of high-KDPI kidney transplantation (KT) versus the clinical alternative (remaining on the waitlist until receipt of a lower KDPI kidney) remains unknown. Using time-dependent Cox regression, we evaluated the mortality risk associated with high-KDPI KT (KDPI 71-80, 81-90 or 91-100) versus a conservative, lower KDPI approach (remain on waitlist until receipt of KT with KDPI 0-70, 0-80 or 0-90) in first-time adult registrants, adjusting for candidate characteristics. High-KDPI KT was associated with increased short-term but decreased long-term mortality risk. Recipients of KDPI 71-80 KT, KDPI 81-90 KT and KDPI 91-100 KT reached a "break-even point" of cumulative survival at 7.7, 18.0 and 19.8 months post-KT, respectively, and had a survival benefit thereafter. Cumulative survival at 5 years was better in all three high-KDPI groups than the conservative approach (p < 0.01 for each comparison). Benefit of high-KDPI KT was greatest in patients age >50 years and patients at centers with median wait time ≥33 months. Recipients of high-KDPI KT can enjoy better long-term survival; a high-KDPI score does not automatically constitute a reason to reject a deceased donor kidney. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

2014-01-01

Recent allocation policy changes have increased sharing of deceased donor livers across local boundaries, and sharing even broader than this has been proposed as a remedy for persistent geographic disparities in liver transplantation. It is possible that broader sharing might increase cold ischemia time (CIT) and thus harm recipients. We constructed a detailed model of transport modes (driving, helicopter, or fixed-wing) and transport times between all hospitals, and investigated the relationship between transport time and CIT for deceased donor liver transplants. Median estimated transport time for regionally shared livers was 2.0 hours compared with 1.0 hours for locally allocated livers. Model-predicted transport mode was flying for 90% of regionally shared livers but only 22% of locally allocated livers. Median CIT was 7.0 hours for regionally shared livers compared with 6.0 hours for locally allocated livers. Variation in transport time accounted for only 14.7% of the variation in CIT and, on average, transport time comprised only 21% of CIT. In conclusion, non-transport factors play a substantially larger role in CIT than does transport time. Broader sharing will have only a marginal impact on CIT but will significantly increase the fraction of transplants that are transported by flying rather than driving. PMID:24975028

Dual kidney transplantation (DKT) from donors at the extremes of age represents one approach to expanding the organ donor pool. The purpose of this study was to review our experience with DKT from older donors and en bloc KT (EBKT) from small pediatric donors. Deceased donor KTs performed at our center between October 2001 and November 2005, were reviewed retrospectively. If the calculated creatinine clearance in an expanded criteria donor was <65 mL/min, then the kidneys were transplanted dually into a single adult recipient. If a pediatric donor weighed <15 kg, then the kidneys were transplanted en bloc. In both instances, low-risk recipients were chosen (primary transplant, low sensitization, body mass index <25 kg/m(2), human leukocyte antigen matching). Donor, recipient, and transplant characteristics, waiting time, and outcomes were examined. Of a total of 279 deceased donor KTs during the 49-month study period, 15 (5%) recipients underwent DKT and 5 (2%) underwent EBKT. Mean donor age was 65.4 years and 21.4 months in the DKT and EBKT groups, respectively. Patient survival rates in both groups were 100% with a mean follow-up of 22 months (minimum, 6 months). Kidney graft survival rates were 80% (12/15) and 60% (3/5) in the DKT and EBKT groups, respectively. The combined incidence of delayed graft function was 10%. Mean 12-month glomerular filtration rates were 46 mL/min and 66 mL/min in the DKT and EBKT groups, respectively. DKT using kidneys from marginal elderly donors and EBKT from small pediatric donors appear to offer a viable option to counteract the shortage of acceptable kidney donors.

A systematic review and synthesis of quantitative and qualitative research were undertaken to examine attitudes to deceased donation and registration as an organ donor among ethnic minorities in the U.K. and North America. A systematic search and assessments of relevance and quality were conducted. Parallel syntheses were then undertaken of 14 quantitative and 12 qualitative papers followed by their integration. The synthesis was organised around five barriers that emerged as key issues: (1) knowledge regarding deceased donation and registration as a donor; (2) discussion of donation/registration with family members; (3) faith and cultural beliefs; (4) bodily concerns including disfigurement and intactness; and (5) trust in doctors and the health care system. In all countries, knowledge of organ donation and registration remained low despite public campaigns, with African-Americans and Black African and Black Caribbean populations in the U.K. often regarding organ donation as a 'white' issue. Each of the four attitudinal barriers was also more prevalent among ethnic minorities compared with the majority population. However, the significance of trust and uncertainties regarding religion/faith differed between groups, reflecting salient aspects of ethnic identity and experiences. Differences were also identified within ethnic groups associated with age and generation, although respect for the views of elders often influenced younger peoples' willingness to donate. There is a need for a more nuanced understanding of ethnicity and of variations in attitudes associated with country of origin, age/generation, socio-economic status and area of residence, to inform public campaigns and promote sensitive discussions with bereaved ethnic minority families. The traditional focus on knowledge and attitudes also requires to be complemented by a greater emphasis on organisational and service-related barriers and changes required to enhance ethnic minorities' access to registration as a donor and consent to deceased donation.

The aim of this study was to evaluate the diagnostic efficiency of the acoustic radiation force impulse (Siemens Medical Solutions, Erlangen, Germany) elastography in assessment of fibrosis in orthotopic liver transplant patients. We enrolled 28 orthotopic liver transplant patients (deceased and living donors), whose biopsy decision had been prospectively given clinically. Ten acoustic radiation force impulse elastographic measurements were applied before the biopsy or within 3 days after the biopsy by 2 radiologists. After the core tissue needle biopsy, specimens of all patients were analyzed according to the modified Ishak scoring system. Measurements of acoustic radiation force impulse elastography and pathology specimen results were compared. From 28 biopsies, fibrosis scores of 4 biopsies were evaluated as F0 (14.3%), 16 as F1 (57.1%), 4 as F2 (14.3%), and 4 as F3 (14.3%). Mean results of acoustic radiation force impulse measurements were calculated as 1.4 ± 0.07 in F0, 1.74 ± 0.57 in F1, 2.19 ± 0.7 in F2, and 2.18 ± 0.35 in F3. There were no significant correlations of mean acoustic radiation force impulse values between the F0 versus F1 (P = .956) and F0 versus F2 stages (P = .234). A statistically significant correlation of mean acoustic radiation force impulse values was found between the F0 and F3 fibrosis stages (P = .046). Acoustic radiation force impulse imaging is a promising screening test for detecting significant liver fibrosis (≥ F3 in modified Ishak) in living-donor or deceased-donor orthotopic liver transplant recipients.

MSUD is an autosomal recessive metabolic disorder that results from a defect in the BCKDH enzyme. This enzyme is essential for the second step in the metabolism of the branched-chain amino acids, leucine, isoleucine, and valine. Patients with MSUD are subject to severe, irreversible neurologic injury unless closely managed with a specialized metabolic formula and a diet restricted in leucine throughout their lifetime. During times of illness, patients with MSUD can suffer from severe metabolic derangement, acute cerebral edema, and untimely death. Deceased donor liver transplant restores the ability to metabolize branched-chain amino acids, even on an unrestricted diet, and prevents metabolic derangements during times of illness. We report a successful case of living donor (parental) transplant for a child with MSUD. The donor was the child's father. This approach has been controversial as parents of children with MSUD are obligate heterozygotes for the condition and have diminished levels of BCKDH activity. If effective, living-related donor transplant provides a promising alternative for deceased donor liver transplant, which often requires a prolonged waiting period and may not be feasible in areas with limited medical resources. © 2016 John Wiley & Sons A/S.

Histidine-Tryptophan-Ketoglutarate (HTK) solution is increasingly used to flush and preserve organ donor kidneys, with efficacy claimed equivalent to University of Wisconsin (UW) solution. We observed and reported increased graft pancreatitis in pancreata flushed with HTK solution, which prompted this review of transplanting HTK-flushed kidneys. We analyzed outcomes of deceased-donor kidneys flushed with HTK and UW solutions with a minimum of 12 months follow-up, excluding pediatric and multi-organ recipients. We evaluated patient and graft survival and rejection rates, variables that might constitute hazards to graft survival and renal function. Two-year patient survival, rejection, renal function and graft survival were not different, but early graft loss (<6 months) was worse in HTK-flushed kidneys (p < 0.03). A Cox analysis of donor grade, cold ischemic time, panel reactive antibodies (PRA), donor race, first vs. repeat transplant, rejection and flush solution showed that only HTK use predicted early graft loss (p < 0.04; relative risk = 3.24), almost exclusively attributable to primary non-function (HTK, n = 5 (6.30%); UW, n = 1 (0.65%); p = 0.02). Delayed graft function and early graft loss with HTK occurred only in lesser grade kidneys, suggesting it should be used with caution in marginal donors.

Living-donor vs deceased-donor liver transplantation for patients with hepatocellular carcinoma.

With the increasing prevalence of living-donor liver transplantation (LDLT) for patients with hepatocellular carcinoma (HCC), some authors have reported a potential increase in the HCC recurrence rates among LDLT recipients compared to deceased-donor liver transplantation (DDLT) recipients. The aim of this review is to encompass current opinions and clinical reports regarding differences in the outcome, especially the recurrence of HCC, between LDLT and DDLT. While some studies report impaired recurrence - free survival and increased recurrence rates among LDLT recipients, others, including large database studies, report comparable recurrence - free survival and recurrence rates between LDLT and DDLT. Studies supporting the increased recurrence in LDLT have linked graft regeneration to tumor progression, but we found no association between graft regeneration/initial graft volume and tumor recurrence among our 125 consecutive LDLTs for HCC cases. In the absence of a prospective study regarding the use of LDLT vs DDLT for HCC patients, there is no evidence to support the higher HCC recurrence after LDLT than DDLT, and LDLT remains a reasonable treatment option for HCC patients with cirrhosis.

Some considerations on the current debate about typing resolution in solid organ transplantation.

The shortage of suitable organs and achieved tolerance are uncontested main concerns in transplantation. Long waiting lists for deceased donors and limited numbers of living donors are the current scenarios. Kidney grafts from living donors have better overall survival compared to cadaveric and require less aggressive immunosuppressive regimens. The human leukocyte antigen (HLA) labs have the key role to test the recipient and donors compatibility based on typing and antibody profile. The current standard molecular procedure in solid organ transplantation is low-resolution typing, at the antigen level. In this commentary, the merits of high versus low degree of typing resolution in solid organ transplantation are discussed. Critical questions and reasons to bring high-resolution typing as a routine test in health system are considered. Specifically, with the introduction of the next-generation sequencing (NGS) in HLA, the pros and cons in living donation and benefits after deceased donation are critically evaluated. NGS has the potential to improve the transplant rates and the overall graft survival. Alternative strategies to increase in demanding the number of transplants are briefly highlighted.

Improving the management of potential organ donors in the intensive care unit could meet an important public health goal by increasing the number and quality of transplantable organs. However, randomized clinical trials are needed to quantify the extent to which specific interventions might enhance organ recovery and outcomes among transplant recipients. Among several barriers to conducting such studies are the absence of guidelines for obtaining informed consent for such studies and the fact that deceased organ donors are not covered by extant federal regulations governing oversight of research with human subjects. This article explores the underexamined ethical issues that arise in the context of donor management studies and provides ethical guidelines and suggested regulatory oversight mechanisms to enable such studies to be conducted ethically. We conclude that both the respect that is traditionally accorded to the prior wishes of the dead and the possibility of postmortem harm support a role for surrogate consent of donors in such randomized controlled trials. Furthermore, although recipients will often be considered human subjects under federal regulations, several ethical arguments support waiving requirements for recipient consent in donor management randomized controlled trials. Finally, we suggest that new regulatory mechanisms, perhaps linked to existing regional and national organ donation and transplantation infrastructures, must be established to protect patients in donor management studies while limiting unnecessary barriers to the conduct of this important research.

Kidney transplants with expanded criteria donor have been associated with improved patient survival compared to those who remain on dialysis. To compare renal function and survival of the kidney graft of deceased donor with expanded criteria and standard criteria over a year in a single transplant center. 255 kidney transplant recipients with deceased donor were included in the study between the years 2011 to 2013 and they were separated into two groups according to the type of donor (expanded criteria donor - ECD - and standard criteria donor - SCD). 231 deceased donor transplants (90.6%) were performed with standard criteria donor (SCD) and 24 (9.4%) with expanded criteria donor (ECD). There was no difference in the prevalence of delayed graft function - DGF - (62.9% vs. 70.8%; p = 0.44). Expanded criteria donor group had lower glomerular filtration rate (GFR) at the end of the 1st year (56.8 ± 26.9 vs. 76.9 ± 23.7; p = 0.001). Patient survival was significantly lower in the ECD group, but the graft survival was not different after death-censored analysis. The ECD group was associated with significantly lower levels of GFR during the first year of transplant and a lower patient survival at the 1st year when compared to the SCD. A aceitação dos rins com critério expandido de doação tem sido associada com melhor sobrevida do paciente em comparação àqueles que permanecem em terapia dialítica. Comparar a função renal e a sobrevida do enxerto renal de doador falecido critério expandido com os de doador falecido critério padrão ao longo de um ano em um único centro de transplantes. Foram incluídos 255 receptores de transplante renal com doador falecido, realizados entre os anos de 2011 a 2013, sendo divididos em dois grupos segundo o tipo de doador (critério expandido - DCE - ou padrão -DCP). Foram avaliados 231 receptores com doador critério ideal (90,6%) e 24 com doador critério expandido (9,4%). Não houve diferença na prevalência de função retardada do enxerto - DGF - (62,9% no DCP vs. 70,8% no DCE; p = 0,44) nos dois grupos. Os transplantes com DCE apresentaram uma taxa de filtração glomerular (TFG) significativamente inferior aos 12 meses (56,8 ± 26,9 vs. 76,9 ± 23,7; p = 0,001). A sobrevida dos pacientes em 1 ano foi significativamente inferior no grupo de DCE, mas não houve diferença na sobrevida dos enxertos após exclusão de perdas por óbito com rim funcionante. O grupo com DCE associou-se com níveis significativamente mais baixos de TFG ao longo do primeiro ano de transplante, bem como uma menor sobrevida dos pacientes em 1 ano, quando comparado ao grupo com doador padrão.

A report from a high-volume single center indicated a survival benefit of receiving a kidney transplant from an HLA-incompatible live donor as compared with remaining on the waiting list, whether or not a kidney from a deceased donor was received. The generalizability of that finding is unclear. In a 22-center study, we estimated the survival benefit for 1025 recipients of kidney transplants from HLA-incompatible live donors who were matched with controls who remained on the waiting list or received a transplant from a deceased donor (waiting-list-or-transplant control group) and controls who remained on the waiting list but did not receive a transplant (waiting-list-only control group). We analyzed the data with and without patients from the highest-volume center in the study. Recipients of kidney transplants from incompatible live donors had a higher survival rate than either control group at 1 year (95.0%, vs. 94.0% for the waiting-list-or-transplant control group and 89.6% for the waiting-list-only control group), 3 years (91.7% vs. 83.6% and 72.7%, respectively), 5 years (86.0% vs. 74.4% and 59.2%), and 8 years (76.5% vs. 62.9% and 43.9%) (P<0.001 for all comparisons with the two control groups). The survival benefit was significant at 8 years across all levels of donor-specific antibody: 89.2% for recipients of kidney transplants from incompatible live donors who had a positive Luminex assay for anti-HLA antibody but a negative flow-cytometric cross-match versus 65.0% for the waiting-list-or-transplant control group and 47.1% for the waiting-list-only control group; 76.3% for recipients with a positive flow-cytometric cross-match but a negative cytotoxic cross-match versus 63.3% and 43.0% in the two control groups, respectively; and 71.0% for recipients with a positive cytotoxic cross-match versus 61.5% and 43.7%, respectively. The findings did not change when patients from the highest-volume center were excluded. This multicenter study validated single-center evidence that patients who received kidney transplants from HLA-incompatible live donors had a substantial survival benefit as compared with patients who did not undergo transplantation and those who waited for transplants from deceased donors.

The objectives of this study are to describe the mechanism of the program and to present initial donor outcome. This is a descriptive study evaluating the performance of a national program for nondirected kidney donation from living unrelated donors (LURDs) in the Philippines in its 3-year implementation. It explains the mechanism of the program and socioeconomic and clinical profiling of donors. Frequencies and percentages were used to measure donor demographic data, medical follow-up compliance rate, and employment predonation and postdonation. Diagnostic laboratory criteria were required to show donor clinical profiles. In 2002, the local Health Department issued an administrative order to create a National Transplant Ethics Committee (NTEC) to address issues of rampant organ sale and donor exploitation. It also set guidelines and intended to oversee transplantation from LURDs. Salient points to the program are as follows: (1) prohibition of sale; (2) accreditation of transplantation centers; (3) enrollment of waitlisted patients in both deceased donor and nondirected LURD program; (4) ethics committee evaluation of LURDs; (5) creation of a national kidney transplant wait list and live donor registry allowing centralized, nondirected kidney allocation; (6) 10% cap on allocation to foreigners; (7) creation of a kidney donor monitoring unit with free 10-year annual medical follow-up for feedback evaluation on donor outcome; and (8) allowance of gratitudinal gifts such as health and life insurance, reimbursement for lost income, educational plan, and job placement to LURDs run by a foundation. From 2004 to 2006, 695 potential donors enrolled; 97 were accepted and deemed medically fit to donate. The remaining 598 were rejected due to demand for outright sale (103), medical unsuitability (77), disapproval by the Ethics Committee (12), and retracted consent (406). Of the 97 qualified donors, 79 had donated, 9 were being evaluated, and 9 await allocation at the end of 2006. Donor demographics show the following: 54% (381) single, 77% (538) males, and 70% (488) aged 21-40 years old. Sixty-eight of 79 became small-scale entrepreneurs postdonation. Also, 53% (42 of 79) complied with medical follow-up requirements. Mean serum creatinine level at 6 months, 1 years, and 2 years were 1.3, 1.33, and 1.05 mg/dL, respectively. Two donors had trace protein and 1 had (+1) protein. The majority of the donors are single males, aged 21-40 years with blue collar jobs. Major reasons for dropouts are retracted consent and medical unsuitability. Donors have improved socioeconomic status. In this study, 53% complied with expected medical follow-up, showing mean serum creatinine within normal range. Proteinuria appeared in 2 of 79 donors. This regulated approach provides a rational, accessible, and equitable donor allocation program. It safeguards the rights of donors and avoids donor exploitation and proliferation of unregulated organ sale. Data collection on their postoperative renal function will show long-term outcome of kidney donation from live donors.

Background and objectives The influence of deceased-donor AKI on post-transplant outcomes is poorly understood. The few published studies about deceased-donor preimplant biopsy have reported conflicting results regarding associations between AKI and recipient outcomes. Design, setting, participants, & measurements This multicenter study aimed to evaluate associations between deceased-donor biopsy reports of acute tubular necrosis (ATN) and delayed graft function (DGF), and secondarily for death-censored graft failure, first adjusting for the kidney donor risk index and then stratifying by donation after cardiac death (DCD) status. Results Between March 2010 and April 2012, 651 kidneys (369 donors, 4 organ procurement organizations) were biopsied and subsequently transplanted, with ATN reported in 110 (17%). There were 262 recipients (40%) who experienced DGF and 38 (6%) who experienced graft failure. DGF occurred in 45% of kidneys with reported ATN compared with 39% without ATN (P=0.31) resulting in a relative risk (RR) of 1.13 (95% confidence interval [95% CI], 0.9 to 1.43) and a kidney donor risk index–adjusted RR of 1.11 (95% CI, 0.88 to 1.41). There was no significant difference in graft failure for kidneys with versus without ATN (8% versus 5%). In stratified analyses, the adjusted RR for DGF with ATN was 0.97 (95% CI, 0.7 to 1.34) for non-DCD kidneys and 1.59 (95% CI, 1.23 to 2.06) for DCD kidneys (P=0.02 for the interaction between ATN and DCD on the development of DGF). Conclusions Despite a modest association with DGF for DCD kidneys, this study reveals no significant associations overall between preimplant biopsy-reported ATN and the outcomes of DGF or graft failure. The potential benefit of more rigorous ATN reporting is unclear, but these findings provide little evidence to suggest that current ATN reports are useful for predicting graft outcomes or deciding to accept or reject allograft offers.

Our aim was to evaluate short term survival rates in renal transplant recipients from deceased donors, while focusing on recipients with diabetes mellitus background. This is a longitudinal follow-up study based on national registry of recipients in Ministry of Health and Medical Education in Iran from 2010-11. Five hundred fifty-five recipients, 226 (40.8%) females and 328 (59.2%) males, were included in the study. Mean (± SD) age of the recipients was 39 ± 14 years. Of donors 18.4% were females and 81.6% were males. Age of the donors was 33 ± 14 years. All allograft recipients from deceased donors enrolled in the study. Short-term graft survival (1 year) was determined. Data regarding age, gender, background disease and cold ischemic time of recipients and donors were collected from the organ procurement units. Allografts were functioning in 499 (90.1%) of recipients after one year. Of recipients 38 (6.9%) died and rejection of transplanted kidney occurred in 17 (3.1%) cases. So, in 55 (9.9%) cases, allografts were not functioning. There were significant relationships between short term graft survival of donors' gender, age of recipients, cold ischemic time and level of clearance of creatinine of recipients. In addition to cold ischemic time, graft survival can be affected by recipients' age. There are some other considerations and implications regarding the short term graft survival in renal transplantation from cadaver donors which are discussed in this paper.

Donor age is a well-known factor influencing graft function after deceased donor liver transplantation (DDLT). However, the effect of donors older than recipients on graft outcomes remains unclear. This study investigated the relationship between the donor-recipient age gradient (DRAG) and posttransplant outcomes after DDLT. We included 164 adult recipients who underwent DDLT between May 1996 and April 2011. Patients were divided into 2 groups according to the value of DRAG: Negative (DRAG -20 to -1; n = 99) versus positive (DRAG 0-20; n = 65). Medical records were reviewed and laboratory data were retrospectively collected. The median age of donors and recipients was 43 (range, 10-80) and 46 (range, 19-67) years, respectively. The mean follow-up time was 57.4 months. A positive DRAG had a negative effect on levels of alkaline phosphatase until 2 weeks after transplantation. However, the positive group showed a lower incidence of hepatitis B viral disease recurrence. The 1-, 3-, and 5-year graft survival rates were 80.4%, 76.8%, and 71.4% in the negative group, and 65.8%, 58.4%, and 56.3% in the positive group, respectively. The positive DRAG group showed significantly inferior graft survival compared with the negative DRAG group (P = .036). This study demonstrated that donors older than recipients had a deleterious effect on graft outcomes. DRAG could be a meaningful determinant of graft survival among DDLT recipients.

BACKGROUND China officially launched a pilot program of organ donation after cardiac death to overcome the shortage of available organs since 2011. Voluntary organ donation by deceased citizens became the only source of transplant organs beginning January 1, 2015. To investigate public opinions on organ donation by deceased donors, and discuss the effect of these opinions on the willingness and attitude of the public regarding voluntary organ donation. MATERIAL AND METHODS We designed a questionnaire. The survey was conducted from December 2014 to January 2015 in Changsha City, and 417 valid questionnaires were recovered. RESULTS A total of 162 respondents explicitly expressed a willingness to donate organs, and 269 believed that the organ donors' relatives should be compensated. A total of 255 respondents thought it acceptable to complete the donation-consent form when receiving a driver's license. Among the respondents, 65.3% did not agree with the statement "My body is bestowed by my parents, and to donate my body parts would not display filial respect"; 88.9% agreed that "It is necessary to consider the willingness of my family"; 74.4% agreed that "Donated organs have not been fairly and appropriately used; the wealthy and celebrities have been favored"; and 61.4% agreed that "Organ donation laws and regulations are not well developed, and organ donations will result in unnecessary difficulties." More than 80% believed that organ donation and transplantation extend life. CONCLUSIONS Public opinions on organ donation after death are associated with various factors, including traditional values, religious beliefs, compensation mechanisms, donor registration, institutional credibility, and ideals.

Recent allocation policy changes have increased the sharing of deceased donor livers across local boundaries, and sharing even broader than this has been proposed as a remedy for persistent geographic disparities in liver transplantation. It is possible that broader sharing may increase cold ischemia times (CITs) and thus harm recipients. We constructed a detailed model of transport modes (car, helicopter, and fixed-wing aircraft) and transport times between all hospitals, and we investigated the relationship between the transport time and the CIT for deceased donor liver transplants. The median estimated transport time was 2.0 hours for regionally shared livers and 1.0 hour for locally allocated livers. The model-predicted transport mode was flying for 90% of regionally shared livers but for only 22% of locally allocated livers. The median CIT was 7.0 hours for regionally shared livers and 6.0 hours for locally allocated livers. Variation in the transport time accounted for only 14.7% of the variation in the CIT, and the transport time on average composed only 21% of the CIT. In conclusion, nontransport factors play a substantially larger role in the CIT than the transport time. Broader sharing will have only a marginal impact on the CIT but will significantly increase the fraction of transplants that are transported by flying rather than driving. © 2014 American Association for the Study of Liver Diseases.

Perioperative risk assessment for successful kidney transplant in leigh syndrome: a case report.

Leigh syndrome (LS) is a rare neurodegenerative mitochondrial disorder which typically presents in childhood but has a varied clinical course. Renal involvement such as proximal tubulopathy in patients with mitochondrial disorders has been described. However, end stage renal disease (ESRD) is uncommon and literature regarding patients undergoing kidney transplantation is limited. Successful deceased donor renal transplant has not been previously described in a patient with Leigh Syndrome. We report a 21-year-old Han Chinese man who presented with limb weakness and unsteady gait, which progressed rapidly over a period of months until he was wheelchair-bound. He subsequently developed ESRD and was commenced on hemodialysis. Investigations revealed a m.13513G > A mutation with clinical and radiological features consistent with LS. His mitochondrial disease stabilised and he underwent a multidisciplinary assessment for deceased donor kidney transplantation to identify and minimise the LS-associated perioperative risks and potential negative effects of immunosuppressants on his LS. Successful kidney transplantation followed with excellent graft function three and a half years post-transplant and improvement in the patient's physical function. This case highlights the importance of careful pre-transplant perioperative risk assessment and post-transplant care in a rare and heterogeneous neurological disease to achieve an ultimately excellent clinical outcome. To our knowledge, this is the first report of successful deceased donor kidney transplant in a patient with known LS.

Deceased donors (DDs) with the brain death due to head injury are the major source of organs for transplantation. The incidence of post-head injury disseminated intravascular coagulation (DIC) ranges from 24% to 50%. Many centers do not accept organs from donors with DIC due to increased risk of primary graft non-function and/or high chances of morbidity/mortality. We performed two successful renal transplants from a DD with head injury with DIC and deranged renal function. One of the recipients developed transient thrombocytopenia, but there was no evidence of DIC or delayed graft functions in either of the recipients. Over a follow-up of 1 month, both are doing well with stable graft function and hematological profile. Thus, a carefully selected DD with severe DIC even with deranged renal function is not a contraindication for organ donation if other risk factors for primary non-function are excluded. This approach will also help in overcoming organ shortage.

Objective: To compare intermediate-term outcomes in adult recipients of expanded criteria (ECD) versus concurrent standard criteria (SCD) deceased donor kidney transplants at a single center using a standardized approach. Summary Background Data: Expanded criteria donors (ECDs) are a source of kidneys that increase the donor organ pool, but the value of transplanting these kidneys has been questioned because of concerns regarding diminished survival and predicted poorer intermediate-term outcomes. Methods: Over a 47-month period, we performed 244 deceased donor kidney transplants into adult recipients, including 143 from SCDs and 101 from ECDs. Management algorithms were implemented to preserve nephron function, and recipient selection for an ECD kidney transplant was based on low immunologic risk. All patients received depleting antibody induction in combination with tacrolimus and mycophenolate mofetil. A total of 188 patients (77%) had at least a 1-year follow-up. Results: ECDs were older, had a higher BMI, had an increased incidence of cerebrovascular brain death and preexisting donor hypertension, and had a lower estimated creatinine clearance (CrCl, all P < 0.01) compared with SCDs. Cold ischemic times were similar between groups, but more ECD kidneys were preserved with pulsatile perfusion (P < 0.01). ECD kidney recipients were older, less sensitized, had a lower BMI, had fewer 0-antigen mismatches, and had a shorter waiting time (all P < 0.01) compared with SCD kidney recipients. Actual patient (93%) and kidney graft (83%) survival rates were similar between groups with a mean follow-up of 24 months. The rates of delayed graft function (DGF), acute rejection, readmissions, operative complications, major infections, and resource utilization were comparable between groups. Renal function followed longitudinally was consistently better in SCD patients (P < 0.05). Black recipients had higher rates of DGF, acute rejection, and graft loss (P < 0.05), but the effects were less pronounced in the ECD group. Conclusions: By appropriate donor and recipient profiling and the use of management algorithms to project and protect renal function, excellent intermediate-term outcomes can be achieved with ECD kidney transplants that are comparable to SCD kidney transplants.

Trends in unrelated-donor kidney transplantation in the developing world.

Living unrelated donors (LUDs) constitute an incremental source of kidneys for transplantation at a global level. Excellent outcomes are reported, superior to those of deceased-donor transplantation and comparable to related donor transplantation. LUD include six categories: spouses, distant relatives, paired-exchange, living-deceased exchange, and non-directed and directed donors. Although a financial reward may be involved in any of these categories, it is in the declared selling of organs that ethical concerns have intensified. There are three patterns of paid LUDs in the developing world: organized, erratic and commercial. The only model of organized LUDs is in Iran, where a central agency assigns and compensates the donors. Erratic LUD transplantation has been experienced, and subsequently banned, in the development of transplant programmes in most developing countries. However, the tightness and enforcement of the official ban are geographically different, providing variable room for uncontrolled trafficking. Commercial transplantation has, thus, become phenomenal in a few countries, gradually evolving into an organized business that follows market dynamics, including advertisement, brokerage, commissions, auctions and tourism. While most international organizations and activist groups condemn commercial transplantation, it is often perceived, in certain cultures and under particular socioeconomic standards, as a human right that meets the demands of all stakeholders, and should be organized rather than declined just for the purpose of meeting the values of a third party.

Deceased donor (DD) kidney quality is determined by calculating the Kidney Donor Profile Index (KDPI). Optimizing high KDPI (≥85%) DD transplant outcome is challenging. This retrospective study was performed to review our high KDPI DD transplant results to identify clinical practices that can improve future outcomes. We retrospectively calculated the KDPI for 895 DD kidney recipients transplanted between 1/2002 and 11/2013. Age, race, body mass index (BMI), retransplantation, gender, diabetes (DM), dialysis time, and preexisting coronary artery disease (CAD) (previous myocardial infarction (MI), coronary artery bypass (CABG), or stenting) were determined for all recipients. About 29.7% (266/895) of transplants were from donors with a KDPI ≥85%. By Cox regression older age, diabetes, female gender, and dialysis time >4 years correlated with shorter patient survival time. Diabetics with CAD who received a high KDPI donor kidney had a significantly increased risk of death (HR 4.33 (CI 1.82-10.30), P=.001) compared to low KDPI kidney recipients. The Kaplan-Meier survival curve for diabetic recipients of high KDPI kidneys was significantly worse if they had preexisting CAD (P<.001 by log-rank test). Patient survival using high KDPI donor kidneys may be improved by avoiding diabetic candidates with preexisting CAD. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Liver transplantation from a deceased donor with β-thalassemia intermedia is not contraindicated: A case report.

The use of extended criteria donors who might have previously been deemed unsuitable is an option to increase the organ supply for transplantation. This report presents a pediatric case of a successful liver transplantation from a donor with β-thalassemia intermedia. A patient, 6-year-old female, with a diagnosis of cryptogenic liver cirrhosis underwent deceased donor liver transplantation from a thalassemic donor. Extreme hyperferritinemia was detected shortly after transplantation. The most probable cause of hyperferritinemia was iron overload secondary to transplantation of a hemosiderotic liver. Hepatocellular injury due to acute graft rejection might have contributed to elevated ferritin levels by causing release of stored iron from the hemosiderotic liver graft. Iron chelation and phlebotomy therapies were started simultaneously in the early postoperative period to avoid iron-related organ toxicity and transplant failure. Follow-up with monthly phlebotomies after discharge yielded a favorable outcome with normal transplant functions. Thalassemia intermedia patients can be candidates of liver donors to decrease pretransplant waitlist mortality. After transplantation of a hemosiderotic liver, it is important to monitor the recipient in terms of iron overload and toxicity. Early attempts to lower iron burden including chelation therapy and/or phlebotomy should be considered to avoid organ toxicity and transplant failure. © 2017 John Wiley & Sons A/S.

2013-03-01

Israel's organ donation rate has always been among the lowest in Western countries. In 2008 two new laws relevant to organ transplantation were introduced. The Brain-Respiratory Death Law defines the precise circumstances and mechanisms to determine brain death. The Organ Transplantation Law bans reimbursing transplant tourism involving organ trade, grants prioritization in organ allocation to candidates who are registered donors and removes disincentives for living donation by providing modest insurance reimbursement and social supportive services. The preliminary impact of the gradual introduction and implementation of these laws has been witnessed in 2011. Compared to previous years, in 2011 there was a significant increase in the number of deceased organ donors directly related to an increase in organ donation rate (from 7.8 to 11.4 donors per million population), in parallel to a significant increase in the number of new registered donors. In addition the number of kidney transplantations from living donors significantly increased in parallel to a significant decrease in the number of kidney transplantations performed abroad (from 155 in 2006 to 35 in 2011). The new laws have significantly increased both deceased and living organ donation while sharply decreasing transplant tourism. © Copyright 2012 The American Society of Transplantation and the American Society of Transplant Surgeons.

With passage of the HIV Organ Policy Equity (HOPE) Act, people living with HIV (PLWH) can donate organs to PLWH awaiting transplant. Understanding knowledge and attitudes regarding organ donation among PLWH in the US is critical to implementing the HOPE Act. PLWH were surveyed regarding their knowledge, attitudes, and beliefs about organ donation and transplantation at an urban academic HIV clinic in Baltimore, MD between 08/2016-10/2016. Responses were compared using Fisher's exact and chi-squared tests. Among 114 survey respondents, median age was 55 years, 47.8% were female, and 91.2% were African American. Most were willing to be deceased donors (79.8%) or living donors (62.3%). Most (80.7%) were aware of the US organ shortage; however, only 24.6% knew about the HOPE Act and only 21.1% were registered donors. Respondents who trusted the medical system or thought their organs would function adequately in recipients were more likely to be willing to be deceased donors (p<0.001). Respondents who were concerned about surgery, worse health post-donation, or need for changes in HIV treatment due to donation were less likely to be willing to be living donors (p<0.05 for all). Most believed that PLWH should be permitted to donate (90.4%) and that using HIV+ donor organs for transplant would reduce discrimination against PLWH (72.8%). Many of the PLWH surveyed expressed willingness to be organ donors. However, knowledge about the HOPE Act and donor registration was low, highlighting a need to increase outreach.

The increasing number of patients requiring transplantation has brought about a shortage of donor kidneys. Incentives can potentially improve organ donation. There is a need to know if the public can accept incentivized organ donation. To evaluate knowledge and opinions on organ donation and compensating the donor/donor family and to determine factors affecting consent. The third survey in 2009 covered 15 regions, 29 provinces, and 14 cities in the National Capital Region. There were 1500 respondents interviewed using a structured questionnaire. Analysis used Statistical Package for Social Science and chi-square. Of the respondents, 63% were females and 74% were married. Nearly half were between 26 and 45 years old. Fewer than 5% were unschooled. Monthly household income was less than USD $222.00 in 70% of respondents. A majority knew about donation from 2001 to 2009. Fewer than 20% knew about deceased donors. Those who wanted to become donors decreased. Sixty-five percent were willing to donate a brain-dead relative's organs. Respondents felt that kidney donors deserve a token of gratitude. Options included livelihood (32%), cash (31%), and educational assistance (26%). Sixty percent wanted the donor assistance termed a "token of gratitude." Consent for donation was positively correlated (P < .05) with higher education and monthly income. Awareness on organ transplantation and donation increased. Factors that promote organ donation are higher education and monthly income. A majority of Filipinos felt that the donor deserves a token of gratitude. Public acceptance of incentivized organ donation may be pursued. Strategies to improve the national advocacy campaign for deceased donation are needed. Copyright © 2012 Elsevier Inc.

The availability of donor organs limits the number of patients in need who are offered liver transplantation. Measures to expand the donor pool are crucial to prevent on-list mortality. The aim of this study was to evaluate the use of livers from deceased donors who were older than 75 years. Fifty-four patients who received a first liver transplant (D75 group) from 2001 to 2011 were included. Donor and recipient data were collected from the Nordic Liver Transplant Registry and medical records. The outcome was compared with a control group of 54 patients who received a liver graft from donors aged 20 to 49 years (D20-49 group). Median donor age was 77 years (range, 75-86 years) in the D75 group and 41 years (range, 20-49 years) in the D20-49 group. Median recipient age was 59 years (range, 31-73 years) in the D75 group and 58 years (range, 31-74 years) in the D20-49 group. The 1-, 3-, and 5-year patient/graft survival values were 87/87%, 81/81%, and 71/67% for the D75 group and 88/87%, 75/73%, and 75/73% for the D20-49 group, respectively. Patient (P = 0.89) and graft (P = 0.79) survival did not differ between groups. The frequency of biliary complications was higher in the D75 group (29.6/13%, P = 0.03). Selected livers from donors over age 75 years should not be excluded based on age, which does not compromise patient or graft survival despite a higher frequency of biliary complications.

Background There is an ongoing expert debate with regard to financial incentives in order to increase organ supply. However, there is a lacuna of empirical studies on whether citizens would actually support financial incentives for organ donation. Methods Between October 2008 and February 2009 a quantitative survey was conducted among German students of medicine and economics to gain insights into their point of view regarding living and deceased organ donation and different forms of commercialization (n = 755). Results The average (passive) willingness to donate is 63.5% among medical students and 50.0% among students of economics (p = 0.001), while only 24.1% of the respondents were actually holding an organ donor card. 11.3% of students of economics had signed a donor card, however, the number is significantly higher among students of medicine (31.9%, p < 0.001). Women held donor cards significantly more often (28.6%) than men (19.4%, p = 0.004). The majority of students were against direct payments as incentives for deceased and living donations. Nevertheless, 37.5% of the respondents support the idea that the funeral expenses of deceased organ donors should be covered. Women voted significantly less often for the coverage of expenses than men (women 31.6%, men 44.0%, p = 0.003). The number of those in favor of allowing to sell one’s organs for money (living organ donation) was highest among students of economics (p = 0.034). Conclusion Despite a generally positive view on organ donation the respondents refuse to consent to commercialization, but are in favor of removing disincentives or are in favor of indirect models of reward.

Graft failure due to chronic rejection is greater among renal transplant patients with donor-specific antibody (DSA) than among DSA-free patients. For patients dependent on deceased donor transplantation, preoperative desensitization to eliminate DSAs may be impractical. We speculated that perioperative desensitization might eliminate preexisting DSAs and prevent de novo DSAs and improve graft outcomes. We report that brief perioperative desensitization using either intravenous immunoglobulin (IVIG) or plasmapheresis/IVIG (PP/IVIG) treatment improves clinical outcomes among patients with positive crossmatches. Immediately following deceased donor transplantation, 235 renal recipients were assigned points for PRA and flow crossmatches (FCXM): delayed graft function (DGF) ≤ 1 point received standard therapy; 2 points received high-dose IVIG; and ≥3 points received PP/IVIG. The DSAs were serially monitored by single antigen bead luminex for 1 year. Five-year clinical outcomes were determined from the chart review. All desensitized patients had preoperatively positive FCXM with DSA. Rejection was more common (P < .05) among desensitized than nonsensitized groups. However, overall graft survivals were similar between the groups (P = not significant) and superior to historic untreated patients (P < .05). Treatment with PP/IVIG more effectively eliminated preexisting DSAs (67% vs 33%, P < 0.05) than IVIG, but neither regimen prevented de novo formation of DSA (20%, P = not significant). Graft survival was >90% in all desensitizated patients with DSA elimination as well as PP/IVIG patients with residual DSA. In contrast, IVIG patients with persistent DSA had poorer graft survival (45%, P < .05). Preemptive perioperative desensitization improved overall graft survival of sensitized patients compared to historic untreated patients. Plasmapheresis/IVIG had greater impact on DSA eradication and graft survival than IVIG alone. © 2016, NATCO.

Between April 1995-December 2003, 1,324 deceased donor kidney transplantations were performed in 139 transplant institutes in Japan. Of these, 45 transplants were from heart-beating and 1,279 transplants were from non-heart-beating deceased donors (NHBDD). Clinical outcomes for the 1,279 recipients of NHBDD kidney transplants were investigated. The overall 5-year patient and graft survival rates were 90% and 72%, respectively. A total of 112 NHBDD kidney grafts never functioned after transplantation and the recipients had to remain on dialysis. The causes of nonfunction were rejection, primary nonfunction, death, thrombosis and others in the order of the incidence. The major causes of graft loss were nonfunction, death, chronic rejection and acute rejection in that order. Major causes of recipient deaths were pneumonia, sepsis and CVA within 12 months, and heart diseases, sepsis, malignancy and pneumonia more than 12 months after transplantation. Kidneys from female donors, donors aged 15 or less or over age 60, donors with extrinsic causes of death other than head trauma, recipients over age 60 and those with diabetic nephropathy as their original disease were found to be at risk for poor graft survival. The lowest and last donor serum creatinine level did not influence the incidence of nonfunction or graft survival. However, graft survival was significantly poorer among recipients of older "expanded" donor kidneys than for recipients of younger grafts. The warm and total ischemia times should be kept shorter than 30 minutes (better 15 minutes), and 12 hours, respectively to minimize the incidence of nonfunction and early graft loss. It is especially important in cases with WIT over 30 minutes that the total ischemia should be kept within 12 hours. Cannulation before cardiac standstill was important to reduce the incidence of nonfunction and achieve high graft survival rates with NHBDD kidneys. The discontinuance of ventilator support also reduced the incidence of graft nonfunction. The combination of CsA or Tacrolimus and MMF as both the induction and maintenance regimen significantly improved graft survival. The use of either anti-T cell antibodies or basiliximab was also associated with significantly better graft survival for NHBDD kidneys. The combination of basiliximab, CsA and MMF resulted in a graft survival rate of 98% at one and 2 years.

The shortage of donor organs has led to increasing use of extended criteria donors, including older donors. The upper limit of donor age that produces acceptable outcomes continues to be explored. In liver transplantation, with appropriate selection, graft survival and patient outcomes would be comparable regardless of age. We performed a retrospective analysis of 1,036 adult orthotopic liver transplantations (OLT) from a prospectively maintained database performed between January 1, 2000 and December 31, 2013. The study focus group was liver transplantations performed using grafts from older (older than 60 years) deceased donors. Deceased donor liver transplantations done during the same time period using grafts from younger donors (younger than 60 years) were analyzed for comparison. Both groups were further divided based on recipient age (less than 60 years and 60 years or older). Donor age was the primary variable. Recipient variables included were demographics, indication for transplantation, Model for End-Stage Liver Disease (MELD), graft survival, and patient survival. Operative details and postoperative complications were analyzed. Patient demographics and perioperative details were similar between groups. Patient and graft survival rates were similar in the 4 groups. Rates of rejection (p = 0.07), bile leak (p = 0.17), and hepatic artery thrombosis were comparable across all groups (p = 0.84). Hepatitis C virus recurrence was similar across all groups (p = 0.10). Thirty-one young recipients (less than 60 years) received grafts from donors aged 70 or older. Their survival and other complication rates were comparable to those in the young donor to young recipient group. Comparable outcomes in graft and patient survivals were achieved using older donors (60 years or more), regardless of recipient age, without increased rate of complications.

Organ donation and transplantation statistics in Belgium for 2012 and 2013.

PubMed

Desschans, B; Evrard, P

2014-11-01

The 2012 and 2013 solid organ transplantation statistics were presented during the annual meeting of the Belgian Transplant Society. All data presented were collected from Eurotransplant International Foundation and/or from all individual Belgian transplant centers. It was demonstrated that the highest number of deceased donors detected (1310) from which 47.8% were an effective organ donor that corresponded to 29 per million inhabitants (pmi) in 2012 and 27.4 pmi in 2013. Out of 626 effective deceased organ donors, 491 (79%) were donors after brain death (DBD) and 135 (21%) donors after circulatory death (DCD), respectively. The majority (125/135; 93%) of DCD donors were DCD Maastricht category III donors and there were 7 (5%) donations following euthanasia. Family refusal tended to be lower for DCD (10.4%) compared to DBD donors (13.4%). Despite the increasing DCD donation rate, DBD donation remains stable in Belgium. The donor age is still increasing, reaching a median age of 53 years (range 0-90). Spontaneous intracranial bleeding (39.3%) and cranio-cerebral trauma (25%) remained the most frequent reasons of death. The number of living related kidney transplantations (57 in 2012 and 63 in 2013) followed the international trend albeit in Belgium it is still very limited. Nevertheless this activity could explain that the number of patients waiting for kidney transplantation (770) reached an absolute minimum in 2013. Except the reduced waiting list for lung transplantation (from 119 patients in 2011 to 85 in 2013), the waiting list remained stable for the other organs but almost 200 patients still died while on the waiting list. Belgium demonstrated the highest number of effective organ donors that corresponded to 29 per million inhabitants (pmi) in 2012 and 27.4 pmi in 2013. Thus far, and in contrast with other countries, there is no erosion of DBD in the DCD donor organ pool, but it is the important responsibility of all transplant centers and donor hospitals to avoid a substitution from DBD by DCD donors.

Background and objectives There is a shortage of kidneys for transplant, and many patients on the deceased donor kidney transplant waiting list would likely benefit from kidneys that are currently being discarded. In the United States, the most common reason given for discarding kidneys retrieved for transplant is procurement biopsy results. This study aimed to compare biopsy results from discarded kidneys with discard attributed to biopsy findings, with biopsy results from comparable kidneys that were successfully transplanted. Design, setting, participants, & measurements In this retrospective, observational, case-control study, biopsy reports were examined from 83 kidneys discarded in 2010 due to biopsy findings (cases), 83 contralateral transplanted kidneys from the same donor (contralateral controls), and 83 deceased donors randomly matched to cases by donor risk profile (randomly matched controls). A second procurement biopsy was obtained in 64 of 332 kidneys (19.3%). Results The quality of biopsy reports was low, with amounts of tubular atrophy, interstitial inflammation, arteriolar hyalinosis, and acute tubular necrosis often not indicated; 69% were wedge biopsies and 94% used frozen tissue. The correlation between first and second procurement biopsies was poor; only 25% of the variability (R2) in glomerulosclerosis was explained by biopsies being from the same kidney. The percentages of glomerulosclerosis overlapped substantially between cases, contralateral controls, and randomly matched controls: 17.1%±15.3%, 9.0%±6.6%, and 5.0%±5.9%, respectively. Of all biopsy findings, only glomerulosclerosis>20% was independently correlated with discard (cases versus contralateral controls; odds ratio, 15.09; 95% confidence interval, 2.47 to 92.41; P=0.003), suggesting that only this biopsy result was used in acceptance decisions. One-year graft survival was 79.5% and 90.7% in contralateral and randomly matched controls, respectively, versus 91.6% among all deceased donor transplants in the Scientific Registry of Transplant Recipients. Conclusions Routine use of biopsies could lead to unnecessary kidney discards. PMID:24558053

With an increased incidence of living-donor kidney transplants, in response to increasing unmet needs for renal transplant, a clear understanding of determinants of posttransplant outcomes is essential. The importance of delayed graft function in deceased-donor kidney transplant is now part of conventional medical wisdom, due to the large amount of evidence focused on this aspect. However, the same is not true for living-donor kidney transplant, partly due to lack of evidence on this crucial clinical question and partly due to lack of awareness about this issue. The current review aims to highlight the importance of delayed graft function as a crucial determinant of outcomes in living-donor kidney transplant. An exhaustive search of online medical databases was performed with appropriate search criteria to collect evidence about delayed graft function after living-donor kidney transplant, with a special focus on studies from the Middle East. Data on incidence, impact, risk factors, and possible prevention modalities of delayed graft function in patients undergoing living-donor kidney transplant are presented. A key finding of this review is that contemporary incidence rates reported from the Middle East are comparatively higher than those reported from outside the region. Although in absolute terms the incidence is lower than deceased donor kidney transplant, the effects of delayed graft function on graft rejection and graft and patient survival are sufficiently large to warrant the formulation of specific treatment protocols. Key to formulating prevention and treatment strategies is identifying discrete risk factors for delayed graft function. Although this evidence is scant, an overview has been provided. Further studies examining different aspects of delayed graft function incidence after living-donor kidney transplant are urgently needed to address a so far little known clinical question.

However, the relationship between pretransplant factors and medium-term outcomes are not fully understood, especially in relation to factors that may vary between centers. Methods The comprehensive national registry of AIT in the United Kingdom was investigated to describe the donor, recipient and transplant characteristics of AIT. Kaplan-Meier analysis was used to compare survival of AIT to all other compatible kidney transplants performed in the United Kingdom. Cox proportional hazards regression modeling was used to determine which pretransplant factors were associated with transplant survival in HLAi and ABOi separately. The primary outcome was transplant survival, taking account of death and graft failure. Results For 522 HLAi and 357 ABO incompatible (ABOi) transplants, 5-year transplant survival rates were 71% (95% confidence interval [CI], 66-75%) for HLAi and 83% (95% CI, 78-87%) for ABOi, compared with 88% (95% CI, 87-89%) for 7290 standard living donor transplants, and 78% (95% CI, 77-79%) for 15 322 standard deceased donor transplants (P < 0.0001). Increased chance of transplant loss in HLAi was associated with increasing number of donor specific HLA antibodies, center performing the transplant, antibody level at the time of transplant, and an interaction between donor age and dialysis status. In ABOi, transplant loss was associated with no use of IVIg, cytomegalovirus seronegative recipient, 000 HLA donor-recipient mismatch; and increasing recipient age. Conclusions Results of AIT were acceptable, certainly in the context of a choice between living donor AIT and an antibody compatible deceased donor transplant. Several factors were associated with increased chance of transplant loss, and these can lead to testable hypotheses for further improving therapy. PMID:28706984

The Netherlands was one of the first countries in Europe to stimulate controlled donation after circulatory death (cDCD) at a national level in addition to donation after brain death (DBD). With this program the number of organ transplants increased, but it also proved to have challenges as will be shown in this 15-year review. Data about deceased organ donation in the Netherlands, from 2000 until 2014, were analysed taking into account the whole donation process from donor referral to the number of organs transplanted. Donor referral increased by 58%, from 213 to 336 donors per year, and the number of organs transplanted rose by 42%. Meanwhile the contribution of cDCD donors increased from 14% in 2000 to 54% in 2014 among all referrals. The organs were transplanted from 92-99% of referred DBD donors, but this percentage was significantly lower for cDCD donors and also decreased from 86% in 2000-2002 to 67% in 2012-2014. In 16% of all referred cDCD donors, organs were not recovered because donors did not die within the expected two-hour time limit after withdrawal of life- upporting treatment. Furthermore, cDCD is more often performed at a higher donor age, which is associated with a lower percentage of transplanted organs. Although cDCD resulted in more transplants, the effort in donor recruitment is considerably higher. Important challenges in cDCD that need further attention are the time limit after withdrawal of life-supporting treatment and donor age, as well as the possibilities to stimulate non-renal transplants including the heart by machine preservation.

Increasing the supply of kidneys for transplantation by making living donors the preferred source of donor kidneys.

PubMed

Testa, Giuliano; Siegler, Mark

At the present time, increasing the use of living donors offers the best solution to the organ shortage problem. The clinical questions raised when the first living donor kidney transplant was performed, involving donor risk, informed consent, donor protection, and organ quality, have been largely answered. We strongly encourage a wider utilization of living donation and recommend that living donation, rather than deceased donation, become the first choice for kidney transplantation. We believe that it is ethically sound to have living kidney donation as the primary source for organs when the mortality and morbidity risks to the donor are known and kept extremely low, when the donor is properly informed and protected from coercion, and when accepted national and local guidelines for living donation are followed.

Liver Transplantation: East versus West

Liver transplantation (LT) has evolved rapidly since the first successful liver transplant performed in1967. Despite a humble beginning, this procedure gained widespread acceptance in the western world as a suitable option for patients with end stage liver disease (ESLD) by the beginning of the 1980s. At present, approximately 25,000 liver transplants are being performed worldwide every year with approximately 90% one year survival. The techniques of living donor liver transplantation (LDLT) developed in East Asia in the 1990s to overcome the shortage of suitable grafts for children and scarcity of deceased donors. While deceased donor liver transplantation (DDLT) constitutes more than 90% of LT in the western world, in India and other Asian countries, most transplants are LDLT. Despite the initial disparity, outcomes following LDLT in eastern countries have been quite satisfactory when compared to the western programs. The etiologies of liver failure requiring LT vary in different parts of the world. The commonest etiology for acute liver failure (ALF) leading to LT is drugs in the west and acute viral hepatitis in Asia. The most common indication for LT due to ESLD in west is alcoholic cirrhosis and hepatitis C virus (HCV), while hepatitis B virus (HBV) predominates in the east. There is a variation in prognostic models for assessing candidature and prioritizing organ allocation across the world. Model for end–stage liver disease (MELD) is followed in United States and some European centers. Other European countries rely on the Child–Turcotte–Pugh (CTP) score. Some parts of Asia still follow chronological order of listing. The debate regarding the best model for organ allocation is far from over. PMID:25755506

Introduction Bile duct size discrepancy in liver transplantation may increase the risk of biliary complications. The aim of this study was to evaluate the safety and outcomes of the eversion bile duct anastomosis technique in deceased donor liver transplantation (DDLT) with duct to duct anastomosis. Methods A total of 210 patients who received a DDLT with duct to duct anastomosis from 2012 to 2017 were divided into two groups: those who had eversion bile duct anastomosis (N=70) and standard bile duct anastomosis (N=140). Biliary complications rates were compared between the two groups. Results There was no difference in the cumulative incidence of biliary strictures (P=0.20) and leaks (P=0.17) between the two groups. The biliary complication rate in the eversion group was 14.3% and 11.4% in the standard anastomosis group. All the biliary complications in the eversion group were managed with endoscopic stenting. A severe size mismatch (≥3:1 ratio) was associated with a significantly higher incidence of biliary strictures (44.4%) compared to 2:1 ratio (8.2%), (P=0.002). Conclusion The use of the eversion technique is a safe alternative for bile duct discrepancy in deceased donor liver transplantation; however, severe bile duct size mismatch may be a risk factor for biliary strictures with such technique.

Liver donor characteristics have a significant impact on graft quality and, in turn, recipient outcomes. In this study, we examined deceased liver donor characteristics and donor risk index (DRI) trends in Canada over the past decade. Data were extracted from the Canadian Organ Replacement Register and Transplant Québec for the decade (2000-2010). Trends in the DRI and donor characteristics, including age, race, height, cause of death (COD), location, cold ischemia time (CIT), and type of donation, were examined. In all, 3746 transplants using deceased liver donors were analyzed. The age of donors, the proportion of black donors, the proportion of cerebrovascular accidents as the COD, and the proportion of donation after cardiac death (DCD) donors all increased over the aforementioned time period. The proportion of transplants classified geographically as local increased, and the CIT for donor livers decreased. Although many of the parameters adversely affecting the DRI increased over the study period, the DRI showed only a slightly significant trend of increasing. The increase in these parameters was counteracted by a decrease in modifiable risk factors such as the CIT and distance traveled. The 5-year recipient survival rate increased from 71.43% (1999-2001) to 75.50% (2005-2007); however, this trend was not significant. Although there was an increase in the use of older and DCD organs, recipient survival was not compromised. In conclusion, demographic trends for liver donors in Canada suggest an increase in the use of higher risk donors. However, the overall graft quality has been not compromised because of a decreasing trend for the CIT and an increase in local transplants. Better coordination and allocation practices in liver transplantation across Canada have minimized the risk of graft failure and resulted in good recipient outcomes. © 2013 American Association for the Study of Liver Diseases.

Pakistan's experience with kidney transplantation and trade: a call for international solidarity.

2014-01-01

Pakistan has taken a long and tortuous road towards curbing the trade in organs within its borders. Yet, despite the phenomenal gains, several challenges remain in this area. For example, robust and sustainable deceased donor programmes must be established to meet the needs of a country which has a high prevalence of kidney disease and failure. Further, it is necessary to offer an alternative source of organs for transplantation to desperate patients who resort to buying these from the "market". Cultural factors and religious beliefs about the sanctity and inviolability of the corpse, as well as the lack of public and professional education regarding the procurement of organs from the deceased, pose considerable barriers that must be surmounted. We believe it is equally important that transplant professionals and the governments of affluent countries consider measures to discourage, if not prevent, their citizens from travelling to impoverished countries such as Pakistan to buy organs. Without a commitment, ethical and legal, to international solidarity in this matter, the goals that are already difficult for developing countries to achieve, ie, establishing deceased donor programmes and bringing an end to organ trafficking, will be even harder to achieve.

[Changes in the transplantation world--from altruism to a utilitarian approach].

PubMed

Mor, Eytan

2006-10-01

The lack of organs for transplantation is a worldwide problem that has created a moral conflict between the traditional altruistic basis of organ donation and alternative solutions based on utilitarian grounds. Survival of grafts achieved in recent decades after unrelated living-donor kidney transplantation between spouses is longer than with deceased donor transplantation. This experience justified the extension of kidney donation beyond the traditional close family relationships including: anonymous donors and paired exchange programs. However, unrelated donation of kidneys within altruistic norms could not provide an ultimate solution for the lack of organs for transplantation. On the other hand, globalization and development of advanced medical technology in developing countries that do not provide transplantation for all their citizens, created an opportunity for a worldwide flourish of transplant tourism as an alternative solution for transplant candidates. Transplant tourism functions according to market laws and is profit-driven, as opposed to the legal organ exchange programs in Europe and the U.S.A., which are non-profit and patient-oriented. The transition from trade in kidneys from unrelated living-donors to the use of other organs (heart, lung and liver) from death penalty prisoners in China was only a matter of deciding where to lay the moral border when justifying the act for the sake of life-saving. Considering the inability of current legal altruistic transplantation practice to supply the growing need for organs, healthcare authorities and professional transplantation organizations have to tackle the donor crisis by designing legally acceptable utilitarian solutions. For instance, through the formation of international organ exchange programs under formal agreements or, in the case of kidney transplantation, through the establishment of a regulated compensated donation system.

Transplantation for Wilson's disease occupies 1/3 of the cases for metabolic diseases in Japan. At the end of 2009, 109 transplantations had been performed including three deceased donor cases in the Japanese registry. We herein discuss problems of transplantation for Wilson's disease as well as its indication, timing, and social care. We retrospectively reviewed four fulminant cases and two chronic cases who underwent living donor liver transplantation. There were two boys and two girls. Four adolescents of average age 11.3 years underwent living donor liver transplantation. Duration from onset to transplantation ranged from 10 to 23 days. Average Model for End-stage Liver Disease (MELD) score was 27.8 (range=24-31). All patients were administrated chelates prior to transplantation. MELD, New Wilson's index, Japanese scoring for liver transplantation, and liver atrophy were useful tools for transplantation decision making; however, none of them was an independent decisive tool. Clinical courses after transplantation were almost uneventful. One girl, however, developed an acute rejection episode due to noncompliance at 3 years after transplantation. All patients currently survive without a graft loss. No disease recurrence had been noted even using living related donors. Two adults evaluated for liver transplantation were listed for deceased donor liver transplantation. Both candidates developed cirrhosis despite long-term medical treatment. There were no appropriate living donors for them. There are many problems in transplantation for Wilson's disease. The indications for liver transplantation should be considered individually using some decision-making tools. The safety of the living donor should be paid the most attention.

Background Antioxidant donor pretreatment is one of the pharmacologic strategy proposed to prevent renal ischemia-reperfusion injuries and delayed graft function (DGF). The aim of the study was to investigate whether a donor pretreatment with N-acetylcysteine (NAC) reduces the incidence of DGF in adult human kidney transplant recipients. Methods In this randomized, open-label, monocenter trial, 160 deceased heart-beating donors were allowed to perform 236 renal transplantations from September 2005 to December 2010. Donors were randomized to receive, in a single-blind controlled fashion, 600 mg of intravenous NAC 1 hr before and 2 hr after cerebral angiography performed to confirm brain death. Primary endpoint was DGF defined by the need for at least one dialysis session within the first week or a serum creatinine level greater than 200 μmol/L at day 7 after kidney transplantation. Results The incidence of DGF was similar between donors pretreated with or without NAC (39/118; 33% vs. 30/118; 25.4%; P = 0.19). Requirement for at least one dialysis session was not different between the NAC and No NAC groups (17/118; 14.4% vs. 14/118; 11.8%, P = 0.56). The two groups had comparable serum creatinine levels, estimated glomerular filtration rates, and daily urine output at days 1, 7, 15, and 30 after kidney transplantation as well as at hospital discharge. No difference in recipient mortality nor in 1-year kidney graft survival was observed. Conclusion Donor pretreatment with NAC does not improve delayed graft function after kidney transplantation.

Given the static number of deceased donors, improvements in donor management and organ preservation to increase the number and quality of organs transplanted per donor are more pressing. Because controlled trials provide the best evidence, we conducted a review of English-language literature of trials in donor management and organ preservation to provide a compendium and to promote additional discussion and studies. Eighty-seven reports were retrieved: 13 on hemodynamic and fluid management, 7 on immunosuppressants, 12 on preconditioning, 34 on preservation fluids, and 21 on pulsatile perfusion. Sixteen studies are ongoing. Although hormonal therapy is used widely, additional studies are needed to determine the benefit of thyroid hormone and insulin replacement and to optimize steroid regimens. Dopamine's success in reducing kidney delayed graft function highlights the opportunity for additional preconditioning trials of remote ischemia, gases, opioids, and others. More rapid progress requires addressing unique barriers in consent and research approval, legal constraints precluding research in cardiac death donors, and streamlining collaboration of multiple stakeholders. With little interest from industry, federal funding needs to be increased. While the University of Wisconsin solution still reigns supreme, several promising preservative solutions and additives with not only biophysical but also pharmacological effects are on the cusp of phase 1 to 2 trials. After nearly three decades of uncertainty, the recent success of a European trial has reenergized the topic not only of machine preservation of the kidney but also of other organs evident by trials in progress. However, the costs of such technical innovations merit the burden of rigorous proof from controlled trials.

Living donor liver transplantation (LDLT) may have better immunological outcomes compared to deceased donor liver transplantation (DDLT). The aim of this study was to analyze the incidence of acute cellular rejection (ACR) after LDLT and DDLT. Data from the Adult-to-Adult Living Donor Liver Transplantation (A2ALL) Retrospective Cohort Study on 593 liver transplants done between May 1998 and March 2004 were studied (380 LDLT; 213 DDLT). Median LDLT and DDLT follow-up was 778 and 713 days, respectively. Rates of clinically treated and biopsy-proven ACR were compared. There were 174 (46%) LDLT and 80 (38%) DDLT recipients with ≥1 clinically treated episodes of ACR, whereas 103 (27%) LDLT and 58 (27%) DDLT recipients had ≥1 biopsy-proven ACR episode. A higher proportion of LDLT recipients had clinically treated ACR (P=0.052), but this difference was largely attributable to one center. There were similar proportions of biopsy-proven rejection (P=0.97) and graft loss due to rejection (P=0.16). Longer cold ischemia time was associated with a higher rate of ACR in both groups despite much shorter median cold ischemia time in LDLT. These data do not show an immunological advantage for LDLT, and therefore do not support the application of unique post-transplant immunosuppression protocols for LDLT recipients. PMID:19120082

In islet transplantation, deceased cardiac death (DCD) donation has been identified as a potential extended source. There are currently no studies comparing outcomes between these categories, and our goal was to compare islet isolation success rates and transplantation outcomes between DCD and neurological determination of death (NDD) donors. Islet isolations from 15 DCD and 418 NDD were performed in our centre between September 2008 and September 2014. Donor variables, islet yields, metabolic function of isolated isled and insulin requirements at 1-month post-transplant were compared. Compared to NDD, pancreata from DCD were more often procured locally and donors required less vasopressive support (P < 0.001 and P = 0.023, respectively), but the other variables were similar between groups. Pre- and postpurification islet yields were similar between NDD and DCD (576 vs. 608 × 10(3) islet equivalent, P = 0.628 and 386 vs. 379, P = 0.881, respectively). The metabolic function was similar between NDD and DCD, as well as the mean decrease in insulin requirement at 1-month post-transplantation (NDD: 64.82%; DCD: 60.17% reduction, P = 0.517). These results support the broader use of DCD pancreata for islet isolation. A much larger DCD islet experience will be required to truly determine noninferiority of both short- and long-term outcomes. © 2015 Steunstichting ESOT.

A significant proportion of procured deceased donor kidneys are subsequently discarded. The UK Kidney Fast-Track Scheme (KFTS) was introduced in 2012, enabling kidneys at risk of discard to be simultaneously offered to participating centers. We undertook an analysis of discarded kidneys to determine if unnecessary organ discard was still occurring since the KFTS was introduced. Between April and June 2015, senior surgeons independently inspected 31 consecutive discarded kidneys from throughout the United Kingdom. All kidneys were biopsied. Organs were categorized as usable, possibly usable pending histology, or not usable for implantation. After histology reports were available, final assessments of usability were made. There were 19 donors (6 donations after brain death, 13 donations after circulatory death), with a median (range) donor age of 67 (29-83) years and Kidney Donor Profile Index of 93 (19-100). Reasons for discard were variable. Only 3 discarded kidneys had not entered the KFTS. After initial assessment postdiscard, 11 kidneys were assessed as usable, with 9 kidneys thought to be possibly usable. Consideration of histological data reduced the number of kidneys thought usable to 10 (10/31; 32%). The KFTS scheme is successfully identifying organs at high risk of discard, though potentially transplantable organs are still being discarded. Analyses of discarded organs are essential to identify barriers to organ utilization and develop strategies to reduce unnecessary discard.

Deceased donor kidneys are a scarce resource and there is debate about how to maximize the benefit from each donated kidney while ensuring equity of access to transplants. Allocation of kidneys to waitlisted patients is determined by a computer algorithm, but the decision to waitlist patients or accept the kidneys offered is largely at the discretion of nephrologists. This study aims to elicit nephrologists' perspectives on waitlisting patients for kidney transplant and the allocation of deceased kidneys. We conducted semistructured face-to-face interviews with adult and pediatric nephrologists from 15 Australian nephrology or transplant centers. Transcripts were analyzed for descriptive and analytical themes. 25 nephrologists participated. 5 major themes on waitlisting and deceased donor kidney allocation were identified: patient advocacy (championing their own patients, empowering patients, giving hope, individualizing judgments, patient preferences, and limited autonomy), professional and moral integrity (transparency, avoiding value judgments, and eliminating bias), protecting center reputation (gatekeeping), achieving equity (uniformity, avoiding discrimination, and fairness for specific populations), and maximizing societal benefit (prioritizing best use of kidney, resource implications, favoring social contribution, and improving efficiency of the allocation process). In making individual patient assessments, estimates about outcomes for a patient had to be resolved with whether it was reasonable from a broader societal perspective. Nephrologists expressed their primary responsibility in terms of giving their own patients access to a transplant and upholding professional integrity by maintaining transparency and avoiding value judgments and bias. However, nephrologists perceived an obligation to protect their center's reputation through the selection of "good" patients, and this caused some frustration. Despite having personal preferences for optimizing the balance between societal benefit and equity, nephrologists did not want direct responsibility for ensuring societal benefit in clinical practice. Rather, they placed the onus on policy makers and the community to reconcile such tensions and advocate for societal benefit. Copyright © 2011 National Kidney Foundation, Inc.

More than 1,100 transplants have been performed at WFUBMC, including 60 pediatric transplants and 40 pancreas transplants. The one-year living donor kidney graft survival rate exceeds 90% and the 2 year deceased donor kidney graft survival rate exceeds 80%. The current active waiting list includes more than 300 candidates. Despite more transplants being performed, we continue to under-serve our referral area, which has among the highest rates of hypertension, diabetes, and end stage renal disease in the country. The AOTP has experienced a period of rapid growth over the past 2 years based upon sharing of zero HLA antigen-mismatched kidneys, use of ECD kidneys, liberalization of donor and recipient selection criteria, and the continued development of the pancreas transplant and laparoscopic donor nephrectomy programs. The pancreas transplant program will continue to grow as the waiting list enlarges and matures, with a 200% increase in activity expected within the next few years. The LDKT program will expand as more emphasis is placed on our pretransplant practice, including the more liberal application of laparoscopic donor nephrectomy, which has now become a standard procedure at our WFUBMC is involved in a number of clinical research projects studying new immunosuppressive agents and regimens. In this chapter, we have presented our recent experience with KTX in the elderly, ECD kidneys, alternate day Thymoglobulin administration, valganciclovir prophylaxis, SRL conversion using daclizumab bridge therapy, and pancreas transplantation with portal-enteric drainage. We plan to initiate a number of new protocols in the immediate future, including desensitization of the highly sensitized patient, ABO incompatible transplantation, transplantation of the HIV-positive patient, steroid withdrawal and avoidance regimens, living kidney donation from the anonymous altruistic donor, paired kidney exchanges from living donors, and islet transplantation. WFUBMC remains the most active donor hospital in North Carolina, and a non-heart beating donor protocol has been successfully initiated at our facility. Although much has been accomplished, a number of challenges remain. We look forward to building on our accomplishments, confronting the challenges, and achieving a level of excellence that could only be attained by mutual commitment from a dedicated, multidisciplinary team.

The diagnosis of acute kidney injury (AKI), which is currently defined as an increase in serum creatinine (Scr) concentration, provides little information on the condition's actual cause. To improve phenotyping of AKI, many urinary biomarkers of tubular injury are being investigated. Because AKI cases are not frequently biopsied, the diagnostic accuracy of concentrations of Scr and urinary biomarkers for histologic acute tubular injury is unknown. Cross-sectional analysis from multicenter prospective cohort. Hospitalized deceased kidney donors on whom kidney biopsies were performed at the time of organ procurement for histologic evaluation. (1) AKI diagnosed by change in Scr concentration during donor hospitalization and (2) concentrations of urinary biomarkers (neutrophil gelatinase-associated lipocalin [NGAL], liver-type fatty acid-binding protein [L-FABP], interleukin 18 [IL-18], and kidney injury molecule 1 [KIM-1]) measured at organ procurement. Histologic acute tubular injury. Of 581 donors, 98 (17%) had mild acute tubular injury and 57 (10%) had severe acute tubular injury. Overall, Scr-based AKI had poor diagnostic performance for identifying histologic acute tubular injury and 49% of donors with severe acute tubular injury did not have AKI. The area under the receiver operating characteristic curve (AUROC) of change in Scr concentration for diagnosing severe acute tubular injury was 0.58 (95% CI, 0.49-0.67) and for any acute tubular injury was 0.52 (95% CI, 0.45-0.58). Compared with Scr concentration, NGAL concentration demonstrated higher AUROC for diagnosing both severe acute tubular injury (0.67; 95% CI, 0.60-0.74; P=0.03) and any acute tubular injury (0.60; 95% CI, 0.55-0.66; P=0.005). In donors who did not have Scr-based AKI, NGAL concentrations were higher with increasing severities of acute tubular injury (subclinical AKI). However, compared with Scr concentration, AUROCs for acute tubular injury diagnosis were not significantly higher for urinary L-FABP, IL-18, or KIM-1. The spectrum of AKI cause in deceased donors may be different from that of a general hospitalized population. Concentrations of Scr and kidney injury biomarkers (L-FABP, IL-18, and KIM-1) lack accuracy for diagnosing acute tubular injury in hospitalized deceased donors. Although urinary NGAL concentration had slightly higher discrimination for acute tubular injury than did Scr concentration, its overall AUROC was still modest. Published by Elsevier Inc.

The incidence of delayed graft function (DGF) and unsatisfactory creatinine clearance (UCC) after renal transplantation is significantly higher in Brazil, when compared with that observed in United States or Europe. Deceased donor (DD) characteristics should directly influence the occurrence of these two outcomes. This study aim to evaluate the influence of DD characteristics on DGF and UCC incidence in Brazil. DD clinical and laboratory variables were correlated with outcome's incidence. We evaluated 787 DD whose organs were transplanted in 1298 patients. We noted a high prevalence of vasoactive drugs use (90.2%), hypernatremia (66.6%) and renal dysfunction (34.8%). The incidence of DGF and UCC was 60.6% and 55.2%, respectively. We observed a progressive increase in DGF risk for age groups over 30 years and for cold ischemia time (CIT) greater than 24 hours. DGF risk was two times higher in recipients of donor kidney final serum creatinine (Cr) over than 1.5 mg/dl. Hypertension and CIT over 36 hours was associated with an increasing of 82% and 99% in UCC risk, respectively. Donor age above 40 years was associated with a progressive increase in UCC risk. DD age, renal function, hypertension and prolonged CIT were associated with increased risk DGF and UCC.

In countries without a national organization for retrieval and distribution of organs of the deceased donors, problem of organ shortage is still not resolved. In order to increase the number of kidney transplantations we started with the program of living unrelated - spousal donors. The aim of this study was to compare treatment outcome and renal graft function in patients receiving the graft from spousal and those receiving ghe graft from living related donors. We retrospectively identified 14 patients who received renal allograft from spousal donors between 1996 and 2009 (group I). The control group consisted of 14 patients who got graft from related donor retrieved from the database and matched than with respect to sex, age, kidney disease, immunological and viral pretransplant status, the initial method of the end stage renal disease treatment and ABO compatibility. In the follow-up period of 41 +/- 38 months we recorded immunosuppressive therapy, surgical complications, episodes of acute rejection, CMV infection and graft function, assessed by serum creatinine levels at the beginning and in the end of the follow-up period. All patients had pretransplant negative cross-match. In ABO incompatible patients pretransplant isoagglutinine titer was zero. The patients with a spousal donor had worse HLA matching. There were no significant differences between the groups in surgical, infective, immunological complications and graft function. Two patients from the group I returned to hemodialysis after 82 and 22 months due to serious comorbidities. In spite of the worse HLA matching, graft survival and function of renal grafts from spousal donors were as good as those retrieved from related donors.

In solid organ transplantation, the disparity between donor supply and patients awaiting transplant continues to increase. The organ shortage has led to relaxation of historic contraindications to organ donation. A large percentage of deceased organ donors have been subjected to traumatic injuries, which can often result in intervention that leads to abdominal packing and intensive care unit resuscitation. The donor with this "open abdomen" (OA) presents a situation in which the risk of organ utilization is difficult to quantify. There exists a concern for the potential of a higher risk for both bacterial and fungal infections, including multidrug-resistant (MDR) pathogens because of the prevalence of antibiotic use and critical illness in this population. No recommendations have been established for utilization of organs from these OA donors, because data are limited. Herein, we report a case of a 21-year-old donor who had sustained a gunshot wound to his abdomen, resulting in a damage-control laparotomy and abdominal packing. The donor subsequently suffered brain death, and the family consented to organ donation. A multiorgan procurement was performed with respective transplantation of the procured organs (heart, liver, and both kidneys) into 4 separate recipients. Peritoneal swab cultures performed at the time of organ recovery grew out MDR Pseudomonas aeruginosa on the day after procurement, subsequently followed by positive blood and sputum cultures as well. All 4 transplant recipients subsequently developed infections with MDR P. aeruginosa, which appeared to be donor-derived with similar resistance patterns. Appropriate antibiotic coverage was initiated in all of the patients. Although 2 of the recipients died, mortality did not appear to be clearly associated with the donor-derived infections. This case illustrates the potential infectious risk associated with organs from donors with an OA, and suggests that aggressive surveillance for occult infections should be pursued. © 2012 John Wiley & Sons A/S.

This is a retrospective study that includes four decades of kidney transplant program at our Institute, with a total of 923 kidney transplants in 872 recipients. In this report, the effect of variables in recipient, donor, and transplant on long-term graft survival was analyzed using the Kaplan Meier method with log-rank test for survival comparisons. Global graft survival at our center-analyzed by censoring for death-with-functioning-graft-for 1, 5 and 10 years was 93%, 83% and 74%, respectively, with median survival of 24.5 years. When analyzed for all-cause graft loss, 1, 5 and 10 year survival was 90%, 76% and 61%, with 12.8-year median survival. Variables associated with lower graft survival censored for death-with-functioning-graft were transplantation in an earlier decade, less histocompatibility, younger kidney transplant recipients, no induction therapy, and double drug initial immunosuppression. After Cox's regression multivariate analysis, the risk factors that remained associated with worse survival were younger recipient, earlier transplant decade, and deceased donor.

In this prospective, randomized, open-label, single-center study, we compared the efficacy and safety of two anti-interleukin-2 receptor monoclonal antibodies among adult recipients of at least 1 HLA-mismatched deceased donor renal grafts. Eligible patients were randomized to induction with either basiliximab or daclizumab. Both groups received cyclosporine microemulsion (CsA Neoral), mycophenolate mofetil, and methylprednisolone. An intent-to-treat analysis of 1-year data assessed the incidence of acute rejection episodes, the renal graft function, the safety, and the patient and graft survivals. Among 127 patients, six (10.0%) and seven (11.5%) patients experienced biopsy-confirmed acute rejection at 12 months, in the basiliximab and the daclizumab groups, respectively. Two renal grafts were lost in the basiliximab and six in the daclizumab cohort, one of them due to rejection. One basiliximab and two daclizumab patients died. Hospital treatment was required for 25 and 33 infections in basiliximab and daclizumab groups, respectively. One basal cell carcinoma of skin was detected. One hypersensitivity reaction was observed with daclizumab. At 12 months, serum creatinine was 101+/-28 micromol/L with basiliximab and 109+/-41 micromol/L with daclizumab. Patient survival was 98.4% with basiliximab and 96.7% with daclizumab, and graft survival was 96.8% versus 90.8%, respectively. No significant differences were observed between the groups. Basiliximab or daclizumab combined with triple therapy was an efficient and safe immunosuppression strategy, demonstrated with low incidence of acute rejection episodes, an acceptable adverse event profile, excellent graft function, and high survival rates in adult recipients within the first year after deceased donor renal transplantation.

Intravenous fluid management for deceased donor kidney transplantation is an important, modifiable risk factor for delayed graft function (DGF). The primary objective of this study was to determine if goal-directed fluid therapy using esophageal Doppler monitoring (EDM) to optimize stroke volume (SV) would alter the amount of fluid given. This randomized, proof-of-concept trial enrolled 50 deceased donor renal transplant recipients. Data collected included patient characteristics, fluid administration, hemodynamics, and complications. The EDM was used to optimize SV in the EDM group. In the control group, fluid management followed the current standard of practice. The groups were compared for the primary outcome of total intraoperative fluid administered. There was no difference in the mean (standard deviation) volume of intraoperative fluid administered to the 24 control and 26 EDM patients [2,307 (750) mL vs 2,675 (842) mL, respectively; mean difference, 368 mL; 95% confidence interval (CI), - 87 to + 823; P = 0.11]. The incidence of complications in the control and EDM groups was similar (15/24 vs 17/26, respectively; P = 0.99), as was the incidence of delayed graft failure (8/24 vs 11/26, respectively; P = 0.36). Goal-directed fluid therapy did not alter the volume of fluid administered or the incidence of complications. This proof-of-concept trial provides needed data for conducting a larger trial to determine the influence of fluid therapy on the incidence in DGF in deceased donor kidney transplantation. www.clinicaltrials.gov (NCT02512731).

Intracerebral hemorrhage (ICH) has high acute mortality. The number of potential kidney and liver donors amongst deceased ICH patients was estimated to improve our institutional guidelines on acute care of neurocritical patients to increase organ donation. A chart review was carried out by a multi-professional team for consecutive ICH patients admitted to the emergency department at Helsinki University Central Hospital and dying within 14 days between 2005 and 2010. In all, 955 patients had follow-up data, of whom 254 (27%) died within 14 days and eight ended up as organ donors. An additional 51 potentially suitable donors not different from actual donors were identified: nine suitable for kidney donation, 11 for liver and 31 for both. In 49/51 (96%) cases prognosis seemed non-existent and do-not-resuscitate orders were issued early, which led to refrainment from intensive care in 76.5%. These potential donors differed from those ICH patients surviving a whole year (n = 529) by male preponderance, more severe symptoms (median National Institutes of Health Stroke Scale 25 vs. 6 and Glasgow Coma Scale 7 vs. 15), larger hematoma volumes of 24.8 cm(3) (vs. 6.7), and frequent finding of midline shift and intraventricular rupture of the hemorrhage in admission brain CT. Based on the results, our guidelines were revised towards more active treatment including mechanical ventilation for neurocritical patients at the emergency department for at least 48 h, resulting in an increase in organ donations in 2012. A considerable number of ICH patients are potential organ donors if the evaluation takes place on arrival and organ donation is considered as part of usual end-of-life care. © 2013 The Author(s) European Journal of Neurology © 2013 EFNS.

Cytomegalovirus (CMV) is one of the major infections encountered posttransplantation. UK Guidelines (2003) recommend CMV prophylaxis or screening with preemptive treatment for all high risk recipients. Studies predating the widespread use of CMV prophylaxis have shown that CMV seronegative recipients (R-) receiving a renal allograft from a CMV seropositive donor (D+) have worse outcomes than those avoiding primary CMV infection. Therefore, it has been suggested that CMV matching should be a part of the UK national deceased donor kidney allocation scheme. We examined patient and allograft survival according to donor and recipient CMV serostatus in 10,190 UK adult and pediatric deceased donor renal transplant recipients transplanted between 2000 and 2007. We also ascertained CMV prophylaxis strategies in all UK renal transplant units. Twenty-one of the 22 UK renal transplant centers used prophylactic oral valganciclovir for 3 months posttransplant in the D+R- transplants, having done so for a median of 4 years. Unadjusted data showed that D+R+ rather than D+R- transplants had the lowest patient and allograft survivals at 3 years posttransplant. However, after adjustment for donor age, there was no significant effect of donor and recipient CMV serostatus on allograft or patient survival. These findings suggest that in an era where CMV prophylaxis is used routinely in D+R- transplants, the previously noted adverse effects of primary CMV infection on allograft and patient survival can be avoided (perhaps through a reduction in the incidence and/or severity of primary CMV infection), without using a CMV-matching allocation scheme.

Abstract Living donor liver transplantation (LDLT) has been increasingly embraced around the world as an important strategy to address the shortage of deceased donor livers. The aim of this guideline, approved by the International Liver Transplantation Society (ILTS), is to provide a collection of expert opinions, consensus, and best practices surrounding LDLT. Recommendations were developed from an analysis of the National Library of Medicine living donor transplantation indexed literature using the Grading of Recommendations Assessment, Development and Evaluation methodology. Writing was guided by the ILTS Policy on the Development and Use of Practice Guidelines (www.ilts.org). Intended for use by physicians, these recommendations support specific approaches to the diagnostic, therapeutic, and preventive aspects of care of living donor liver transplant recipients.

Many deceased by neurologic criteria donors are administered inhalational agents during organ recovery surgery-a process that is characterised by warm and cold ischaemia followed by warm reperfusion. In certain settings, volatile anaesthetics (VA) are known to precondition organs to protect them from subsequent ischaemia-reperfusion injury. As such, we hypothesised that exposure to VA during organ procurement would improve post-graft survival. Lifebanc (organ procurement organisation [OPO] for NE Ohio) provided the investigators with a list of death by neurologic criteria organ donors cared for at three large tertiary hospitals in Cleveland between 2006 and 2016-details about the surgical recovery phase were extracted from the organ donors' medical records. De-identified data on graft survival were obtained from the United Network for Organ Sharing (UNOS). The collated data underwent comparative analysis based on whether or not VA were administered during procurement surgery. Records from 213 donors were obtained for analysis with 138 exposed and 75 not exposed. Demographics, medical histories, and organ procurement rates were similar between the two cohorts. For the primary endpoint, there were no significant differences observed in either early (30-day) or late (five-year) graft survival rates for kidney, liver, lung, or heart transplants. Our findings from this retrospective review of a relatively small cohort do not support the hypothesis that the use of VA during the surgical procurement phase improves graft survival. Reviews of larger datasets and/or a prospective study may be required to provide a definitive answer.

Liver transplantation for hepatocellular carcinoma: the Hong Kong experience.

Orthotopic liver transplantation (OLT) is the best treatment option for selected patients with hepatocellular carcinoma (HCC) with the background of cirrhosis since this treatment modality can cure both diseases at once. Over the years, the applicability of OLT for HCC has evolved. In Asia, including Hong Kong, a shortage of deceased donor liver grafts is a universal problem having to be faced in all transplant centers. Living-donor liver transplant (LDLT) has therefore been developed to counteract organ shortage and the high prevalence of HCC. The application of LDLT for HCC is a complex process involving donor voluntarism, selection criteria for the recipient and justification with respect to long-term survival in comparison to the result of deceased donor liver transplant. This article reviews the authors' experience with OLT for HCC patients in Hong Kong, with emphasis on the applicability and outcome of LDLT for HCC. Donor voluntarism has a significant impact on the application of LDLT. "Fast-track" LDLT in the setting of recurrence following curative treatment carries a high risk of recurrence even though the tumor stage fulfills the standard criteria. Although the survival outcome may be worse following LDLT than DDLT for HCC, LDLT is still the main treatment option for patients with transplantable HCC in Hong Kong, and a reasonable survival outcome can be achieved in selected patients with extended indications. It is particularly true that LDLT provides the only hope for patients with advanced HCC under the constricting problem of organ shortage.

Understanding how organ donors' families recover from their grief can help organ procurement organizations improve consent rates and increase the number of deceased donor organs available for transplant. To determine what helps the loved ones of deceased organ donors heal from their grief and loss, and to better understand families' needs during the consent process as a way of improving overall consent rates for organ donation. Written survey of all organ and tissue donors' families in the San Diego and Imperial County (California) service area during 2006 and 2007. Responses to the 20-question survey addressing factors that help healing from grief, as well as contextual information about the families' experience at the hospital and the consent process. Most respondents (84%) indicated that family support was the most helpful thing in dealing with their grief, followed by the support of friends (74%) and religious and cultural beliefs (37%). Most (75%) indicated that they agreed to donation so that something positive could result from their loss. Most respondents (93%) felt that they were given enough information to make an informed decision about donation, and 6% indicated that the donation process interfered with funeral or memorial arrangements. More than 95% understood that their loved one had died before they were approached for consent. Consistent with previous studies, 12% said they still had unanswered questions about aspects of donation, and 15% of respondents indicated that the discussion about organ donation added more emotional stress to their overall experience.

The silence of Good Samaritan kidney donation in Australia: a survey of hospital websites.

It is common for living donor candidates to use the Internet as a tool to enhance their decision-making process. Specifically, the websites of transplant hospitals can potentially be a vital source of information for those contemplating living donation. In an effort to explore the low incidence of Good Samaritan kidney donation (donations to strangers) in Australia, two raters conducted a nine-attribute website content analysis for all hospitals which participate in these transplants (n = 15). Overall, the concept of living donation is relatively silent on Australian hospital websites. Only four hospitals mention their living donor program, and only one mentions their Good Samaritan program. No site linked directly to Australia's AKX Paired Kidney Exchange Program - the only program which facilitates pair and chain transplants in Australia. Further, information about deceased donation is nearly absent as well. An individual with the altruistic desire to donate will generally find scant or absent information about donation at the website of their local transplant hospital, although this information could easily be present as an educational tool which supports the consent process. Using a hospital website to educate the public about a clinical service should not be viewed as ethically problematic (solicitation), but rather an ethical essential. © 2013 John Wiley & Sons A/S.

The growing demand for organ donors to supply the increasing number of patients on kidney waiting lists has led most transplant centers to develop protocols that allow safe use of organs from donors with special clinical situations previously regarded as contraindications. Deceased donors with previous hepatitis B may be a safe resource to increase the donor pool even if there is still controversy among transplantation centers regarding the use of hepatitis B surface antigen-positive donors for renal transplantation. However, when allocated to serology-matched recipients, kidney transplantation from donors with hepatitis B may result in excellent short-term outcome. Many concerns may arise in the long-term outcome, and studies must address the evaluation of the progression of liver disease and the rate of reactivation of liver disease in the recipients. Accurate selection and matching of both donor and recipient and correct post-transplant management are needed to achieve satisfactory long-term outcomes. PMID:27123988

Absence of significant dissent should be sufficient for deceased donor organ procurement in New Zealand.

Douglas, Thomas M; Douglas, Nicholas M

2009-10-01

New Zealand's organ donation rates are among the lowest in the OECD. In a bid to increase organ availability, the New Zealand Human Tissue Act 2008 introduces new consent arrangements for deceased donor organ procurement. This article assesses these new arrangements and presents the case for further reform. Our assessment and arguments are based on philosophical analysis informed by empirical data on the effectiveness of alternative consent systems. We: 1) Identify widely held ethical judgments about policies and practices relevant to organ donation (e.g. those relating to coronial post-mortems), 2) Assess the implications of these judgments for the Human Tissue Act and the assumptions that underpin it, and 3) Derive policy recommendations that are consistent with the judgments. The Human Tissue Act 2008 retains a strong consent requirement for organ procurement: organs may not be transplanted unless either the deceased or the family consents. We argue that organ availability could and should be increased by shifting from a model that requires consent to one that requires the absence of significant dissent. We recommend that New Zealand adopt either 1) an organ donation system similar to the existing system for ordering coronial post-mortems, or 2) a variant of the 'opt-out' system already in place in several other countries.

Balancing hope and despair at the end of life: The contribution of organ and tissue donation.

Walker, Wendy; Sque, Magi

Concern for the grieving family can moderate the intentions of critical care staff to advocate deceased organ and tissue donation. Conversely, benevolent actions may provoke distress through missed opportunities to save or transform lives. This article provides insight into the perceived benefits of organ and tissue donation for grieving families who experienced end-of-life care in the intensive care unit. Data were collected via semistructured, face-to-face or telephone interviews with 43 participants from 31 donor families. Audio recordings were transcribed verbatim and subjected to qualitative content analysis. The study findings affirmed the importance of person-centered end-of-life care. Donor families shared examples of good-quality care and communication that contained the hallmarks of compassion, respect, dignity, and choice. We uncovered a trajectory of hope and despair in which the option of organ and tissue donation appeared to give meaning to the life and death of the deceased person and was comforting to some families in their bereavement. Our study findings underlined the significance of donation decision making for grieving families. Organ and tissue donation has the potential to balance hope and despair at the end of life when the wishes of the dying, deceased, and bereaved are fulfilled. Copyright © 2015 Elsevier Inc.

[Kidney transplantation epidemiology in France].

Kidney transplantation activity in France is among the most important worldwide: in 2011, 2976 transplants have been performed (47.5 per million population), and the number of patients living with a functional graft is estimated around 30,000, representing 44.7% of all patients (n = 67,270) treated for end-stage renal failure. However, the rate of preemptive kidney transplants remains very low, only 3.3% of incident patients starting renal replacement therapy. The analysis of demand showed a progressive increase in recent years, as demonstrated by the registration rate on the kidney transplantation waiting list, increasing by 5% yearly between 2006 and 2010, but with huge differences according to age categories and regional registration areas, reflecting discrepant appreciations in indications for kidney transplantation. The median waiting time between registration and transplantation increased progressively in recent years, reaching 22.3 months with considerable variations according to regional areas and transplantation teams. Kidney transplantation activity, while increasing continuously, is far to cover the rising demand, and inexorably patients accumulate on the waiting list (around 9000 patients were registered by January 2012). This situation is the consequence of insufficient organ procurement activity. The deceased organ procurement rate remained high: 1572 harvested donors in 2011 (24.1 per million population), but the proportion of older donors rose in recent years, to reach the rate of 26% of donors older than 65 years in 2011. The procurement activity of donors after cardiac arrest was reintroduced in 2006, but increased slowly: 65 transplants were performed in 2011 using kidney procured in non heart-beating donors. The living donor kidney transplantation activity has markedly increased recently: 302 living donor transplantations were performed in 2011, representing 10.1% of the kidney transplantations. Facing the predictable increase in the number of candidates, all efforts should be put together, by increasing the living donor transplantation activity and by supporting and promoting the deceased donor procurement activity.

A shortage of transplantable organs is a global problem. There are two types of organ donation: living and deceased. Deceased organ donation can occur following neurological determination of death (NDD) or cardiocirculatory death. Donation after cardiocirculatory death (DCD) accounts for the largest increments in deceased organ donation worldwide. Variations in the use of DCD exist, however, within Canada and worldwide. Reasons for these discrepancies are largely unknown. The purpose of this study is to develop, implement, and evaluate a theory-based knowledge translation intervention to provide practical guidance about how to increase the numbers of DCD organ donors without reducing the numbers of standard NDD donors. We will use a mixed method three-step approach. In step one, we will conduct semi-structured interviews, informed by the Theoretical Domains Framework, to identify and describe stakeholders' beliefs and attitudes about DCD and their perceptions of the multi-level factors that influence DCD. We will identify: determinants of the evidence-practice gap; specific behavioural changes and/or process changes needed to increase DCD; specific group(s) of clinicians or organizations (e.g., provincial donor organizations) in need of behaviour change; and specific targets for interventions. In step two, using the principles of intervention mapping, we will develop a theory-based knowledge translation intervention that encompasses behavior change techniques to overcome the identified barriers and enhance the enablers to DCD. In step three, we will roll out the intervention in hospitals across the 10 Canadian provinces and evaluate its effectiveness using a multiple interrupted time series design. We will adopt a behavioural approach to define and test novel, theory-based, and ethically-acceptable knowledge translation strategies to increase the numbers of available DCD organ donors in Canada. If successful, this study will ultimately lead to more transplantations, reducing patient morbidity and mortality at a population-level.

Induction therapy in deceased donor kidney transplantation is costly, with wide discrepancy in utilization and a limited evidence base, particularly regarding cost-effectiveness. We linked the United States Renal Data System data set to Medicare claims to estimate cumulative costs, graft survival, and incremental cost-effectiveness ratio (ICER - cost per additional year of graft survival) within 3 years of transplantation in 19 450 deceased donor kidney transplantation recipients with Medicare as primary payer from 2000 to 2008. We divided the study cohort into high-risk (age > 60 years, panel-reactive antibody > 20%, African American race, Kidney Donor Profile Index > 50%, cold ischemia time > 24 hours) and low-risk (not having any risk factors, comprising approximately 15% of the cohort). After the elimination of dominated options, we estimated expected ICER among induction categories: no-induction, alemtuzumab, rabbit antithymocyte globulin (r-ATG), and interleukin-2 receptor-antagonist. No-induction was the least effective and most costly option in both risk groups. Depletional antibodies (r-ATG and alemtuzumab) were more cost-effective across all willingness-to-pay thresholds in the low-risk group. For the high-risk group and its subcategories, the ICER was very sensitive to the graft survival; overall both depletional antibodies were more cost-effective, mainly for higher willingness to pay threshold (US $100 000 and US $150 000). Rabbit ATG appears to achieve excellent cost-effectiveness acceptability curves (80% of the recipients) in both risk groups at US $50 000 threshold (except age > 60 years). In addition, only r-ATG was associated with graft survival benefit over no-induction category (hazard ratio, 0.91; 95% confidence interval, 0.84-0.99) in a multivariable Cox regression analysis. Antibody-based induction appears to offer substantial advantages in both cost and outcome compared with no-induction. Overall, depletional induction (preferably r-ATG) appears to offer the greatest benefits.

Combination therapy of intravenous immunoglobulin (IVIG) and rituximab showed a good transplant rate in highly sensitized wait-listed patients for deceased donor kidney transplantation (DDKT), but carried the risk of antibody-mediated rejection. The authors investigated the impact of a new combination therapy of bortezomib, IVIG, and rituximab on transplantation rate.This study was a prospective, open-labeled clinical trial. The desensitization regimen consisted of 2 doses of IVIG (2  g/kg), a single dose of rituximab (375  mg/m), and 4 doses of bortezomib (1.3  mg/m). The transplant rate was analyzed. Anti-Human leukocyte antigen (HLA) DRB antibodies were determined by a Luminex solid-phase bead assay at baseline and after 2, 3, and 6 months in the desensitized patients.There were 19 highly sensitized patients who received desensitization and 17 patients in the control group. Baseline values of class I and II panel reactive antibody (%, peak mean fluorescence intensity) were 83  ±  16.0 (14952  ±  5820) and 63  ±  36.0 (10321  ±  7421), respectively. Deceased donor kidney transplantation was successfully performed in 8 patients (42.1%) in the desensitization group versus 4 (23.5%) in the control group. Multivariate time-varying covariate Cox regression analysis showed that desensitization increased the probability of DDKT (hazard ratio, 46.895; 95% confidence interval, 3.468-634.132; P = 0.004). Desensitization decreased mean fluorescence intensity values of class I panel reactive antibody by 15.5% (20.8%) at 2 months. In addition, a liberal mismatch strategy in post hoc analysis increased the benefit of desensitization in donor-specific antibody reduction. Desensitization was well tolerated, and acute rejection occurred only in the control group.In conclusion, a desensitization protocol using bortezomib, high-dose IVIG, and rituximab increased the DDKT rate in highly sensitized, wait-listed patients.

The aim of this study was to investigate the volume-outcome relationship in kidney transplantation by examining graft and patient outcomes using standardized risk adjustment (observed-to-expected outcomes). A secondary objective was to examine the geographic proximity of low, medium, and high-volume kidney transplant centers in the United States. The significant survival benefit of kidney transplantation in the context of a severe shortage of donor organs mandates strategies to optimize outcomes. Unlike for other solid organ transplants, the relationship between surgical volume and kidney transplant outcomes has not been clearly established. The Scientific Registry of Transplant Recipients was used to examine national outcomes for adults undergoing deceased donor kidney transplantation from January 1, 1999 to December 31, 2013 (15-year study period). Observed-to-expected rates of graft loss and patient death were compared for low, medium, and high-volume centers. The geographic proximity of low-volume centers to higher volume centers was determined to assess the impact of regionalization on patient travel burden. A total of 206,179 procedures were analyzed. Compared with low-volume centers, high-volume centers had significantly lower observed-to-expected rates of 1-month graft loss (0.93 vs 1.18, P<0.001), 1-year graft loss (0.97 vs 1.12, P<0.001), 1-month patient death (0.90 vs 1.29, P=0.005), and 1-year patient death (0.95 vs 1.15, P=0.001). Low-volume centers were frequently in close proximity to higher volume centers, with a median distance of 7 miles (interquartile range: 2 to 75). A robust volume-outcome relationship was observed for deceased donor kidney transplantation, and low-volume centers are frequently in close proximity to higher volume centers. Increased regionalization could improve outcomes, but should be considered carefully in light of the potential negative impact on transplant volume and access to care.

Elevated serum concentrations of soluble CD30 molecule (sCD30) have been related to acute cellular rejection and poor graft outcomes in kidney transplantation. This historical cohort study investigated the association of pretransplant sCD30 serum concentrations with kidney graft function expressed as estimated glomerular filtration rate (GFR) at 3 years after transplantation. Pretransplant sera from 176 adult deceased-donor kidney graft recipients were tested for sCD30 content using a commercially available automated enzyme-linked immunosorbent assay. The immunosuppression consisted of induction therapy with monoclonal anti-CD25 antibodies and a maintenance regimen of cyclosporine (CsA)-based therapy. GFR was estimated (eGFR) by the four-variable Modification of Diet in Renal Disease (MDRD) Study equation. According to the distribution of pretransplant sCD30 levels (median 66.7 U/mL; interquartile range, 46.6 to 98.6 U/mL), a concentration of 66 U/mL or higher was defined as high (n = 89) and below 66 U/mL as low (n = 87). Three years after transplantation, eGFR was not significantly different among recipients in high versus low sCD30 groups (69 +/- 23 mL/min/1.73m2 vs 66 +/- 21 mL/min/1.73m2; P = .327) and there was no correlation between eGFR and pretransplant sCD30 levels (r2 = 0.001; P = .73). Upon multivariate regression analysis, donor age, recipient body mass index at transplantation, and acute rejection episodes were independent variables affecting eGFR at 3 years after transplantation. This study showed that pretransplant sCD30 serum concentrations were not associated with deceased-donor kidney graft function at 3 years after transplantation. The immunosuppression with anti-CD25 antibodies and a triple CsA-based maintenance regimen could possibly be decisive for our findings.

The epidemic of drug overdose deaths in the United States has led to an increase in organ donors. To characterize donors who died of overdose and to analyze outcomes among transplant recipients. Prospective observational cohort study. Scientific Registry of Transplant Recipients, 1 January 2000 to 1 September 2017. 138 565 deceased donors; 337 934 transplant recipients at 297 transplant centers. The primary exposure was donor mechanism of death (overdose-death donor [ODD], trauma-death donor [TDD], or medical-death donor [MDD]). Patient and graft survival and organ discard (organ recovered but not transplanted) were compared using propensity score-weighted standardized risk differences (sRDs). A total of 7313 ODDs and 19 897 ODD transplants (10 347 kidneys, 5707 livers, 2471 hearts, and 1372 lungs) were identified. Overdose-death donors accounted for 1.1% of donors in 2000 and 13.4% in 2017. They were more likely to be white (85.1%), aged 21 to 40 years (66.3%), infected with hepatitis C virus (HCV) (18.3%), and increased-infectious risk donors (IRDs) (56.4%). Standardized 5-year patient survival was similar for ODD organ recipients compared with TDD organ recipients (sRDs ranged from 3.1% lower to 3.9% higher survival) and MDD organ recipients (sRDs ranged from 2.1% to 5.2% higher survival). Standardized 5-year graft survival was similar between ODD and TDD grafts (minimal difference for kidneys and lungs, marginally lower [sRD, -3.2%] for livers, and marginally higher [sRD, 1.9%] for hearts). Kidney discard was higher for ODDs than TDDs (sRD, 5.2%) or MDDs (sRD, 1.5%); standardization for HCV and IRD status attenuated this difference. Inability to distinguish between opioid and nonopioid overdoses. In the United States, transplantation with ODD organs has increased dramatically, with noninferior outcomes in transplant recipients. Concerns about IRD behaviors and hepatitis C among donors lead to excess discard that should be minimized given the current organ shortage. National Institutes of Health.

Objective For various reasons, people of Chinese (China, Hong Kong or Taiwan) and South Asian (Indian subcontinent) ancestry (the two largest ethnic minority groups in Ontario, Canada) may be less likely to register for deceased organ donation than the general public, and their families may be less likely to consent for deceased organ donation at the time of death. Methods We conducted two population-based studies: (1) a cross-sectional study of deceased organ donor registration as of May 2013, and (2) a cohort study of the steps in proceeding with deceased organ donation for patients who died in hospital from October 2008 to December 2012. Results A total of 49 938 of 559 714 Chinese individuals (8.9%) and 47 774 of 374 291 South Asians (12.8%) were registered for deceased organ donation, proportions lower than the general public (2 676 260 of 10 548 249 (25.4%). Among the 168 703 Ontarians who died in a hospital, the families of 33 of 81 Chinese (40.1%; 95% CI: 30.7%-51.6%) and 39 of 72 South Asian individuals (54.2%; 95% CI: 42.7-65.2%) consented for deceased organ donation, proportions lower than the general public (68.3%; 95% CI: 66.4%-70.0%). Conclusions In Ontario, Canada Chinese and South Asian individuals are less likely to register and their families are less likely to consent to deceased organ donation compared to the remaining general public. There is an opportunity to build support for organ and tissue donation in these two large ethnic communities in Canada. PMID:26230320

The German post-mortem organ donation rate has dropped by one third since 2010. Furthermore, 958 patients died in 2015 in Germany while waiting for an organ. To decrease organ shortage, an amendment of the transplantation law was established in 2012. An information package including an organ donor card is sent to all German citizens via the postal service. A voluntary national transplantation register was introduced in 2016 to improve transparency in the organ donation process. The influence of several transplantation scandals starting in 2012 on organ donation rates is in question. Therefore, the objective of this article is to discuss approval and objections to post-mortem organ donation among the next of kin of potential donors and the general public in Germany. Binary logistic regression of data from the 2014 survey by the Federal Centre for Health Education on attitudes towards organ and tissue donation in Germany was conducted, aiming to identify influencing factors on the likelihood of organ donor card possession. Additionally, data of the German Organ Transplantation Foundation on post-mortem organ donations in Germany in 2014 were studied to highlight reasons for approval and objections by next of kin of potential and explanted post-mortem organ donors. Methods of documentation of the deceased's will according to data of the German Organ Transplantation Foundation were analyzed. Male gender and lack of knowledge about organ donation decrease the likelihood of having an organ donor card. Of the respondents in the survey of the Federal Centre for Health Education 71.0% would donate their own organs, whereas only one third possess an organ donor card. Health insurances and physicians are the most important providers of organ donor cards in Germany. An increase in the percentage of organ donor card possession following the amendment of the transplantation law could not be observed by 2016. Fear of organ trade and unjust organ allocation are the main reasons for rejecting organ donation among the general public. Previous transplantation scandals are a primary reason for a negative change in attitudes. Main reasons for objection among the next of kin of potential organ donors are known objections of the deceased and the lack of knowledge about the will of the deceased. In addition, only 58.1% of all explanted organ donors documented their will in written or verbal form. Education on organ donation can be a means to increase organ donation rates. The effects of the change in legislation and the establishment of the transplant register need to be evaluated. Further research regarding the influence of religion, especially among religious minorities, on organ donation rates in Germany needs to be conducted to identify possible obstacles. Moreover, the use of social networks to address potential organ donors has proven to increase registration numbers and could easily be implemented in Germany.

Reassessing marketing of kidneys from the 2008 perspective.

Progressive improvements in all aspects of the kidney transplant regimen establish this form of renal replacement therapy as superior to peritoneal or hemodialysis in terms of extent of rehabilitation and long-term recipient survival. Continuous growth in the number of patients with kidney failure sustained by dialytic therapy has not been associated with substantially increased deceased donor kidney contributions, causing intensified stressful waiting periods for potential recipients lacking a live kidney donor. Neither public relation campaigns nor local government efforts have substantially increased kidney donation. Buying a donor kidney is illegal and condemned as fostering exploitation of poor people by the wealthy. Widely publicized examples of coercion of unwilling donors create a negative image of harmful, inhumane conduct deployed to obtain kidneys sold and transplanted under unsavory circumstances. Yet efforts to establish and test governmental programs to supervise and sustain acceptable standards for the sale and implantation of kidneys from fully informed, medically evaluated and protected, fairly compensated donors have been resisted and frustrated by those who consider such compensation loathsome. Accordingly, while selling kidneys is prohibited by law, pressure from those wanting to quench the number of deaths of wait-listed dialysis patients continues forcing reexamination of an issue that, like prohibition of the possession and sale of alcohol in the United States in 1920, places the will of a people in opposition to unreasonably restrictive laws. The debate continues.

Background The UK has implemented a national strategy for organ donation that includes a centrally coordinated network of specialist nurses in organ donation embedded in all intensive care units and a national organ retrieval service for deceased organ donors. We aimed to determine whether despite the national approach to donation there is significant regional variation in deceased donor kidney donation rates. Methods The UK prospective audit of deaths in critical care was analysed for a cohort of patients who died in critical care between April 2010 and December 2011. Multivariate logistic regression was used to identify the factors associated with kidney donation. The logistic regression model was then used to produce risk-adjusted funnel plots describing the regional variation in donation rates. Results Of the 27 482 patients who died in a critical care setting, 1528 (5.5%) became kidney donors. Factors found to influence donation rates significantly were: type of critical care [e.g. neurointensive vs general intensive care: OR 1.53, 95% confidence interval (CI) 1.34–1.75, P<0.0001], patient ethnicity (e.g. ‘Asian’ vs ‘white’: OR 0.17, 95% CI 0.11–0.26, P<0.0001), age (e.g. age >69 vs age 18–39 yr: OR 0.2, 0.15–0.25, P<0.0001), and cause of death [e.g. ‘other’ (excluding ‘stroke’ and ‘trauma’) vs ‘trauma’: OR 0.04, 95% CI 0.03–0.05, P<0.0001]. Despite correction for these variables, kidney donation rates for the 20 UK kidney donor regions showed marked variation. The overall standardized donation rate ranged from 3.2 to 7.5%. Four regions had donation rates of >2 standard deviations (sd) from the mean (two below and two above). Regional variation was most marked for donation after circulatory death (DCD) kidney donors with 9 of the 20 regions demonstrating donation rates of >2 sd from the mean (5 below and 4 above). Conclusions The marked regional variation in kidney donation rates observed in this cohort after adjustment for factors strongly associated with donation rates suggests that there is considerable scope for further increasing kidney donation rates in the UK, particularly DCD.

NHSBT Tissue Services issues bone to surgeons in the UK in two formats, fresh-frozen unprocessed bone from living donors and processed bone from deceased donors. Processed bone may be frozen or freeze dried and all processed bone is currently subjected to a washing protocol to remove blood and bone marrow. In this study we have improved the current bone washing protocol for cancellous bone and assessed the success of the protocol by measuring the removal of the bone marrow components: soluble protein, DNA and haemoglobin at each step in the process, and residual components in the bone at the end of the process. The bone washing protocol is a combination of sonication, warm water washes, centrifugation and chemical (ethanol and hydrogen peroxide) treatments. We report that the bone washing protocol is capable of removing up to 99.85 % soluble protein, 99.95 % DNA and 100 % of haemoglobin from bone. The new bone washing protocol does not render any bone cytotoxic as shown by contact cytotoxicity assays. No microbiological cell growth was detected in any of the wash steps. This process is now in use for processed cancellous bone issued by NHSBT.

Ethical and legal issues related to the donation and use of nonstandard organs for transplants.

Transplantation of nonstandard or expanded criteria donor organs creates several potential ethical and legal problems in terms of consent and liability, and new challenges for research and service development; it highlights the need for a system of organ donation that responds to an evolving ethical landscape and incorporates scientific innovation to meet the needs of recipients, but which also safeguards the interests and autonomy of the donor. In this article, the use of deceased donor organs for transplants that fail to meet standard donor criteria and the legitimacy of interventions and research aimed at optimizing their successful donation are discussed.

Background: Many families choose not to consent to organ donation at the time of their loved one’s death. In Ontario, Canada, whether these decisions vary by ethnicity remains unclear. Objective: To compare the proportion of families of immigrants who consented for deceased organ donation with families of long-term residents. Design: Population-based retrospective cohort study. Setting: Potential donors in Ontario, Canada, between November 2008 and March 2013. Methods: We used linked administrative databases to study the proportion of families who consented for deceased organ donation. Results: Overall, of the 2873 families of potential donors approached, 1912 (67%) provided consent for deceased organ donation. Families of immigrants were less likely to provide consent compared with families of long-term residents (46% [135 of 291] vs 69% [1777 of 2582]; adjusted rate ratio (RR): 0.72; 95% confidence interval [CI]: 0.63-0.81). When examined by the country of birth, families of immigrants from the following regions were less likely to consent to organ donation compared with long-term residents: South Asia (RR: 0.71; 95% CI: 0.55-0.91), East Asia and Pacific (RR: 0.68; 95% CI: 0.53-0.88) and Middle East, North Africa, and sub-Saharan Africa (RR: 0.58; 95% CI: 0.37-0.91). Limitations: We could not determine why consent was not obtained. We had a small sample of immigrants. We only had access to the potential donors’ information and not the family member who was approached for consent. Many characteristics that we examined were nonmodifiable (eg, age, sex). Conclusions: In Ontario, families of immigrants are less likely to consent to deceased organ donation. There is an opportunity to better understand the reasons for lower consent among certain immigrant groups. PMID:29093824

The status of deceased organ donation is assessed using metrics such as donation/conversation rate, organ yield, and rate of organs recovered for transplant and not transplanted. These metrics are based on eligible deaths (brain death of a person aged 70 years or younger) as well as on actual donors. The 9132 eligible deaths reported in 2013 represented a slight increase over 2012. The donation/conversion rate was 71.3 eligible donors per 100 eligible deaths, a slight decline from 2012, and varied by donation service area from 50.0 to 87.0. The number of organs recovered per donor, 3.55, also varied by donation service area, from 2.79 to 4.10. The mean number of organs transplanted per donor was 3.08 in 2013, slightly higher than 3.02 in 2012. The mean observed/expected organ yield ratio for kidneys varied from 0.86 to 1.18; for pancreata, from 0.29 to 2.59; for livers, from 0.69 to 1.17; for hearts, from 0.68 to 1.41; and for lungs, from 0.33 to 1.41. The rate of organs recovered for transplant and not transplanted in 2013 for all organs combined was 0.13 per recovered organ, slightly lower than the rate of 0.14 in 2012. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Objective: To compare the outcomes of living donor liver transplantation (LDLT) versus deceased donor liver transplantation (DDLT) for patients with hepatocellular carcinoma (HCC) in different selection criteria. Methods: Data of patients with HCC who underwent liver transplantation between 2005 and 2013 at our center were reviewed. Clinical data of LDLT recipients and DDLT recipients were compared. The postoperative recurrence-free survival (RFS) rate and overall survival (OS) rate after LDLT versus DDLT were compared in the Milan recipients, the University of California, San Francisco (UCSF) recipients, the up-to-seven recipients, the Hangzhou recipients and the Chengdu recipients. Results: Data of 255 patients were retrospectively reviewed in this study. Seventeen DDLT recipient and 9 LDLT recipients died during the perioperative period. Among the remaining 229 recipients (NLDLT=66, NDDLT=163), 96 patients met the Milan criteria, 123 recipients met the UCSF criteria, 135 patients met the up-to-seven criteria, 216 patients met the Hangzhou criteria, and 229 recipients met the Chengdu criteria. The overall RFS and OS rates of the Milan recipients, the UCSF recipients, the up-to-seven recipients, the Hangzhou recipients and the Chengdu recipients after LDLT and DDLT were all similar. Conclusion: Using well-studied selection criteria, LDLT offers similar outcomes to DDLT for patient with HCC, even using expanded selection criteria. PMID:26430399

This is the experience in a program of multiorgan transplant at the Hospital de Especialidades 71 in Torreon, Coahuila. It is a historical overview of the beginning and development of the transplant program. Describes the logistics of the study of patients for transplantation and the test to be carried out in the laboratory of histocompatibility. We analyzed the records of the patients were transplanted in the period from January 1987 until June 2011. We found 2538 in total, of which 1940 were renal (76.4%). The 53% were male and 47% female. Average age of 37 +/- 15 years. The 82% was adult population and 18% pediatric. The most frequent cause of CRF was the chronic glomerulonephritis and 15% of the patients are diabetic. 73.5% were living donor and 26.5% were deceased donor. 7% of recipients of living donor have domino transplants. The incidence of acute rejection was 7.5%. 15% of the patients had infections and 60% was urinary. The immunosuppressive scheme most widely used is tacrolimus + mycophenolate mofetil + prednisone. The overall survival of the patient was 100, 90 and 87% to the first, third and fifth year after the transplant. The overall survival of the graft was 98, 87 and 83% in the first, third and fifth years post-transplant. It has been developed a multiple organ transplant program in Torreon that currently is one of the most important in Mexico with similar results to those obtained at the international level.

Objectives This study sought to report 22 years experience in pediatric kidney transplantation in Oman. Methods Electronic charts of all Omani children below 13 years of age who received a kidney transplant from January 1994 to December 2015 were reviewed. Data collected included patient demographics, etiology of end-stage kidney disease, modality and duration of dialysis, donor type, complication of kidney transplantation (including surgical complications, infections, graft rejection) graft and patient survival, and duration of follow-up. Results During the study period transplantation from 27 living related donors (LRDs), 42 living unrelated donors (LURDs), also referred to as commercial transplant, and one deceased donor were performed. The median age at transplantation was nine years for both groups. The most common primary diagnosis was congenital anomalies of the kidney and urinary tract in 32.8% of patients followed by familial nephrotic syndrome in 20.0% and polycystic kidney disease in 18.5%. Almost half the patients were on hemodialysis before transplantation, 35.7% were on peritoneal dialysis, and 14.2% received preemptive renal transplantation. Children who received LURD kidneys had high surgical complications (42.8%) compared to the LRDs group (17.8%). Five patients from LURDs group had early graft nephrectomy and four patients developed non-graft function or delayed graft function. In addition, patients in the LURDs group had a higher incidence of hypertension and acute rejection. Graft and patient survival were both better in the LRDs than the LURDs group. Conclusions Although our pediatric kidney transplant program is a young program it has had successful patient outcomes comparable to international programs. Our study provides evidence that in addition to legal and ethical issues with commercial transplant, it also carries significantly higher morbidity and reduced graft and patient survival.

Under the Universal Health Care Program of the Department of Health, the Philippine Health Insurance Corporation (PHIC) launched the Case Type Z benefit package for kidney transplantation, providing the largest amount (USD $13,300.00) for any single medical procedure. The objective of this study was to describe under the PHIC Case Type Z Benefit Package for kidney transplantation at the National Kidney and Transplant Institute and kidney transplantation outcomes under this package. Included in the benefit were standard risk recipients between 10 and 70 years of age with at least 1 human leukocyte antigen (HLA) DR match with the donor, panel-reactive antibody (PRA) less than 20%, and absence of donor-specific antibody (DSA). Previous transplantations, malignancy, hepatitis B and C, human immunodeficiency virus (HIV) positivity, cytomegalovirus (CMV) R-/D+, congestive heart failure, and liver cirrhosis were exclusion criteria. Patients were evaluated by a medical social worker according to their family's financial status. Since June 2012, a total of 261 patients have received the benefit, with 44 under service, 37 with fixed co-pay and 180 with variable co-pay. Of the living donor kidney transplants, 98% had immediate graft function, with 2.3% (6/261) acute rejection rates at 1 year. The total cost of hospitalization was within the benefit for living donor kidney transplants (less than USD 8000.00) but exceeded it in all cases of deceased donor kidney transplants. The successful use of and excellent outcomes under the Case Type Z benefit demonstrated how collaboration among government agencies, health care providers, and pharmaceutical companies could result in a program that improved the access to health care for Filipino patients with end-stage renal disease.

2014-04-27

In Asia, evidence-based guidelines for the management of hepatocellular carcinoma (HCC) have evolved, including the option of liver transplantation. Because of the continuing serious organ shortage, however, living donor liver transplantation (LDLT) remains the mainstream in Japan. Unlike deceased donor transplantation, living donor transplantation is not always limited by the restrictions imposed by the nationwide organ allocation system. The decision for transplantation may depend on institutional or case-by-case considerations, balancing the will of the donor, the operative risk, and the overall survival benefit. Cumulative data from the Japanese national multicenter registry analysis as well as individual center experiences suggest further expanding the criteria for LDLT for HCC from the Milan criteria is feasible with acceptable outcomes.

Turkey is one of the countries facing a serious organ shortage problem, with thousands of patients with end-stage organ failure. The Social Security Institution started to increase the reimbursement for transplantation operations in 2007 to solve this problem, and this policy has continued since then. Although the number of transplantation centers and operations in Turkey increased in this term, according to organ donation and transplantation statistics from the Ministry of Health, the rate of organ retrieval from deceased organ donors has decreased. This study was performed with the purpose of retrospectively analyzing (between the years 2005 and 2015) the number of brain deaths and donors after brain death in hospitals that are affiliated with the Istanbul Regional Coordination Office and have transplantation units. Data were collected via the website of the Ministry of Health. Hospitals were categorized as those directly affiliated with the Ministry of Health, university hospitals, and private hospitals. This study found that the number of transplantation centers has increased >3 times since 2005, and the number of private transplantation centers has increased 9 times for the same period. We also found that the number of brain deaths, donors after brain death in hospitals, and number of brain deaths and donors after brain death per hospital had varied throughout the study years. Although the number of transplantation centers has increased since 2005, the number of brain deaths and donors after brain death has not increased to the same extent for this period in these hospitals that have transplantation units.

Living donor liver transplantation: eliminating the wait for death in end-stage liver disease?

PubMed

Fisher, Robert A

2017-06-01

Adult-to-adult living donor liver transplantation (A2ALDLT), outside of Asia, remains an important yet underutilized gift of life. For patients with end-stage liver disease, A2ALDLT is a proven transplantation option, with lower waiting list mortality and suffering, and equivalent or better allograft and patient survival than deceased-donor liver transplantation (DDLT). The risks to living donors and the benefit to their recipients have been carefully defined with long-term level 1 and 2 evidence-based study. An overview of the development and practice of living donor liver transplant (LDLT), including donor and recipient surgical allograft innovation, is provided. The issues of recipient selection, outcomes and morbidity, including disease-variable study and challenges past and present are presented in comparison with DDLT cohorts, and future insights are described. Central to practice is the careful and concise review of donor evaluation and selection and donor outcome, morbidity, quality of life and present and future strategies for donor advocacy and growth of the technique.

To evaluate deceased non-heart beating (DNHB) donors and deceased heart beating (DHB) brain-stem dead donors, as sources of viable urological tissue for use in biomedical research. To identify sources of viable human bladder tissue as an essential resource for cell biological research aimed at understanding human diseases of the bladder and for developing new tissue engineering and regenerative medicine strategies for bladder reconstruction. Typically, normal human urinary tract tissue is obtained from adult or paediatric surgical patients with benign urological conditions, but few surgical procedures yield useful quantities of healthy bladder tissue for research. Research ethics committee approval was obtained for collection of donor bladder tissue. Consent for DHB donors was undertaken by the Donor Transplant Coordinators. Tissue Donor Coordinators were responsible for consent for DNHB donors and the retrieval of bladders was coordinated through the National Blood Service Tissue Banking Service. All retrievals were performed by practicing urologists and care was taken to maintain sterility and to minimise bacterial contamination. Two bladders were retrieved from DNHB donors and four were retrieved from DHB donors. By histology, DNHB donor bladder tissue exhibited marked urothelial tissue damage and necrosis, with major loss or absence of urothelium. No cell cultures could be established from these specimens, as the urothelial cells were not viable in primary culture. Bladder urothelium from DHB donors was intact, but showed some damage, including loss of superficial cells and variable separation from the basement membrane. All four DHB bladder specimens yielded viable urothelial cells that attached in primary culture, but cell growth was slow to establish and cultures showed a limited capacity to form a functional barrier epithelium and a propensity to senesce early. We have shown that normal human bladder urothelial cell cultures can be established and serially propagated from DHB donor bladders. However, our study suggests that rapid post-mortem changes to the bladder affect the quality and viability of the urothelium, rendering tissue from DNHB donors an inadequate source for urothelial cell culture. Our experience is that whereas patients are willing to donate surgical tissue for research, there is a barrier to obtaining consent from next of kin for retrieved tissues to be used for research purposes. © 2013 The Authors.

Removing financial barriers to organ and bone marrow donation: the effect of leave and tax legislation in the U.S.

PubMed

Lacetera, Nicola; Macis, Mario; Stith, Sarah S

2014-01-01

Many U.S. states have passed legislation providing leave to organ and bone marrow donors and/or tax benefits for live and deceased organ and bone marrow donations and to employers of donors. We exploit cross-state variation in the timing of such legislation to analyze its impact on organ donations by living and deceased persons, on measures of the quality of the transplants, and on the number of bone marrow donations. We find that these provisions do not have a significant impact on the quantity of organs donated. The leave laws, however, do have a positive impact on bone marrow donations, and the effect increases with the size of the population of beneficiaries and with the generosity of the legislative provisions. Our results suggest that this legislation works for moderately invasive procedures such as bone marrow donation, but these incentives may be too low for organ donation, which is riskier and more burdensome.

The first full year of data after implementation of the new kidney allocation system reveals an increase in deceased donor kidney transplants among black candidates and those with calculated panel-reactive antibodies 98%–100%, but a decrease among candidates aged 65 years or older. Data from 2015 also demonstrate ongoing positive trends in graft and patient survival for both deceased and living donor kidney transplants, but the challenges of a limited supply of kidneys in the setting of increasing demand remain evident. While the total number of patients on the waiting list decreased for the first time in a decade, this was due to a combination of a decrease in the number of candidates added to the list and an increase in the number of candidates removed from the list due to deteriorating medical condition, as well as an increase in total transplants. Deaths on the waiting list remained at, but this was likely because of an increasing trend toward removing inactive candidates too sick to undergo transplant. PMID:28052609

Rectus sheath haematoma (RSH) is rarely thought of as a cause of abdominal pain in renal transplant recipients. A 36-year-old woman, a post-deceased donor renal allograft transplant recipient for chronic interstitial nephritis, on triple drug immunosuppression (tacrolimus, mycophenolate mofetil and prednisolone) with basiliximab induction, developed acute vascular rejection and acute tubular injury with suspected antibody-mediated rejection. While on plasmapheresis and haemodialysis for delayed graft function, she developed acute left lower abdominal pain on the 16th postoperative day with tender swelling in the left paraumbilical region. CT of the abdomen showed a large haematoma in the left rectus sheath with no extension. The patient underwent haematoma evacuation through a left paramedian incision and had an uneventful recovery. Serum creatinine stabilised at 0.8 mg/dL and she is on regular follow-up with excellent graft function at 6 months. Diagnosis requires a high index of suspicion, and prompt treatment prevents morbidity and can expedite patient recovery. 2016 BMJ Publishing Group Ltd.

2016-03-01

Kidney transplant centers are distributed unevenly throughout 58 donor service areas (DSAs) in the United States. Market competition and transplant center density may affect transplantation access and outcomes. We evaluated the role of spatial organization of transplant centers in conjunction with market competition in the conduct of kidney transplantation. The Scientific Registry of Transplant Recipients was queried for market characteristics associated with kidney transplantation between 2003 and 2012. Market competition was calculated using the Herfindahl Hirschman Index. Kidney transplant centers were geocoded to measure spatial organization by the average nearest neighbor (ANN) method. Kidney quality was assessed by kidney donor risk index. A hierarchical negative binomial mixed effects model tested the relationship between market characteristics and annual kidney transplants by DSA. About 152,071 kidney transplants were performed at 229 adult kidney transplant centers in 58 DSAs. Greater market competition was associated with kidney transplant center spatial clustering (P < 0.001). In multivariable analysis, more kidney transplant centers (incidence rate ratio [IRR], 1.04; P = 0.005), 100 more new listings (IRR, 1.02; P = 0.003), 100 more deceased donors (IRR, 1.23; P < 0.001), 100 more new dialysis registrants (IRR, 1.01; P < 0.001), and higher kidney donor risk index (IRR, 1.98; P < 0.001) were associated with increased kidney transplants. After controlling for market characteristics, larger numbers of kidney transplant centers were associated with more kidney transplants and increased utilization of deceased donor kidneys. This underlines the importance of understanding geography as well as competition in improving access to kidney transplantation.

An International Comparison of the Effect of Policy Shifts to Organ Donation following Cardiocirculatory Death (DCD) on Donation Rates after Brain Death (DBD) and Transplantation Rates

During the past decade an increasing number of countries have adopted policies that emphasize donation after cardiocirculatory death (DCD) in an attempt to address the widening gap between the demand for transplantable organs and the availability of organs from donation after brain death (DBD) donors. In order to examine how these policy shifts have affected overall deceased organ donor (DD) and DBD rates, we analyzed deceased donation rates from 82 countries from 2000–2010. On average, overall DD, DBD and DCD rates have increased over time, with the proportion of DCD increasing 0.3% per year (p = 0.01). Countries with higher DCD rates have, on average, lower DBD rates. For every one-per million population (pmp) increase in the DCD rate, the average DBD rate decreased by 1.02 pmp (95% CI: 0.73, 1.32; p<0.0001). We also found that the number of organs transplanted per donor was significantly lower in DCD when compared to DBD donors with 1.51 less transplants per DCD compared to DBD (95% CI: 1.23, 1.79; p<0.001). Whilst the results do not infer a causal relationship between increased DCD and decreased DBD rates, the significant correlation between higher DCD and lower DBD rates coupled with the reduced number of organs transplanted per DCD donor suggests that a national policy focus on DCD may lead to an overall reduction in the number of transplants performed.

Split liver transplantation (SLT) has been widely adopted across Europe, resulting in remarkable reduction in the paediatric waiting-list mortality. Left split graft (LSG) is commonly used for paediatric recipients; however, deceased donor criteria selection are not universal. The aim of this study was to analyse the LSG outcome from the European Liver Transplant Registry and to identify risk factors for graft failure. Data from 1500 children transplanted in 2006-2014 with LSG from deceased donors were retrospectively analysed. Overall, graft losses were 343(22.9%) after 5 years from transplantation, 240(70.0%) occurred within the first 3 months. Estimated patient survival was 89.1% at 3 months and 82.9% at 5 years from SLT. Re-transplantation rate was 11.5%. At multivariable analysis, significant risk factors for graft failure at 3 months included the following: urgent SLT (HR = 1.73, P = 0.0012), recipient body weight ≤6 kg (HR = 1.91, P = 0.0029), donor age >50 years (HR = 1.87, P = 0.0039), and cold ischaemic time (CIT) [HR = 1.07 per hour, P = 0.0227]. LSG has good outcomes and SLT is excellent option for paediatric recipients in the current organ shortage era. We identified practical guidelines for LSG donor and recipient selection criteria: donor age may be safely extended up to 50 years in the absence of additional risk factors; thus, children <6 kg and urgent transplantation need CIT <6 h and appropriate graft/recipient size-matching to achieve good outcomes. © 2018 Steunstichting ESOT.

Living unrelated-commercial-kidney transplantation: when there is no chance to survive.

PubMed

Sever, Mehmet Sukru

2006-10-01

Transplantation is the best treatment of end-stage renal disease (ESRD); however, organ shortage is a reality. Deceased donor organ donation is inadequate; hence, the number of patients on the waiting lists is increasing progressively. Since many ESRD patients do not have living genetically related donors, living unrelated transplantation is considered. These transplantations offer excellent graft and patient survival rates if practiced in conventional situations, while the results are not so favorable or even poor in unconventional transplantations, which mostly take place in developing countries. Ethical aspects of living unrelated transplantation are more complicated than the medical side due to concern of commercialization. Making payment to the donors has been considered strictly as nonethical by many authors, while some others suggest reopening previous debates for kidney sales. The latter claim that if exploitation of donors is avoided, the reward (or payment) to the donor can be morally justified. Apart from these controversies, it is uniformly accepted that commercial transplantation is certainly unethical when brokers are involved or the aim is just profit for transplant physicians, because the main reason in favor of organ sales is improving the quality of life of the patients and the donors, not the brokers or the physicians. All these theoretical ethical arguments in the Western countries turn out to become vital concerns in developing countries, because transplantation is the cheapest renal replacement therapy. Recently, it has been suggested that organ shortage problems can partly be solved by establishing controlled donor compensation programs in these countries, which may also prevent exploitation of the donors. However, it is impossible to suggest a uniform solution for all countries because of deep differences in economical status as well as social and cultural values. Thus, every country should build its own ethical standards for commercial transplantation.

End-of-life practices in patients with devastating brain injury in Spain: implications for organ donation.

To describe end-of-life care practices relevant to organ donation in patients with devastating brain injury in Spain. A multicenter prospective study of a retrospective cohort. 1 November 2014 to 30 April 2015. Sixty-eight hospitals authorized for organ procurement. Patients dying from devastating brain injury (possible donors). Age: 1 month-85 years. Type of care, donation after brain death, donation after circulatory death, intubation/ventilation, referral to the donor coordinator. A total of 1,970 possible donors were identified, of which half received active treatment in an Intensive Care Unit (ICU) until brain death (27%), cardiac arrest (5%) or the withdrawal of life-sustaining therapy (19%). Of the rest, 10% were admitted to the ICU to facilitate organ donation, while 39% were not admitted to the ICU. Of those patients who evolved to a brain death condition (n=695), most transitioned to actual donation (n=446; 64%). Of those who died following the withdrawal of life-sustaining therapy (n=537), 45 (8%) were converted into actual donation after circulatory death donors. The lack of a dedicated donation after circulatory death program was the main reason for non-donation. Thirty-seven percent of the possible donors were not intubated/ventilated at death, mainly because the professional in charge did not consider donation alter discarding therapeutic intubation. Thirty-six percent of the possible donors were never referred to the donor coordinator. Although deceased donation is optimized in Spain, there are still opportunities for improvement in the identification of possible donors outside the ICU and in the consideration of donation after circulatory death in patients who die following the withdrawal of life-sustaining therapy.

2010-01-01

We describe the organization of a high-volume Brazilian kidney transplant program that performed 7,833 transplants in 12 years fulfilling government expectations without compromising the care of the patients. The annual number of kidney transplants increased from 428 in 1999 to 1,048 in 2010. In our Organ Procurement Organization (6.1 million inhabitants) brain death notifications increased from 196 to 468 in 2010 and 35% became actual donors. There are 5,011 patients on the waiting list and recipient selection is based on HLA matching. A significant proportion of the recipients is of black ethnicity and had been for long time on dialysis. Over 700 first appointments for living donation are done every year. After the transplant, the majority of patients are followed locally (200-250 appointments per day). The transplant outcome among living-donor recipients is comparable to large registries but inferior outcome have been observed among recipients of deceased donor organs, though consistent improvement has been seen in more recent years. We also discuss issues related to local regulations and solutions to improve efficiency and outcomes.

Under the influence of traditional oriental culture, the lack of organ donation is especially serious in China and Japan. The aim of this study was to compare Chinese and Japanese college students' attitudes and analyze contributing factors toward deceased donation. An anonymous, self-administered questionnaire comprising 15 questions was distributed to approximately 400 college students at Liaoning University, China, and Kyushu University, Japan. Statistical analysis used SPSS software. Japanese students' attitude towards deceased organ donation was more favorable than that of Chinese students (43.6% versus 35.9%, P = .001). Several factors contributed to positive responses by students from both countries: family perspective on organ donation and transplantation; decision to donate to family members; prior blood donation; living liver or kidney donation; possibility of needing a transplant; and willingness to receive a deceased or a living donor organ. More efforts must emphasize awareness and up-to-date knowledge regarding organ donation among citizens and should be undertaken by the Chinese and Japanese governments. Copyright © 2013 Elsevier Inc.

To fully assess the true risk of prostate cancer transmission in during renal transplantation. A full review of all existing literature relevant to the topic. There has not been a single documented case of transmission of prostate cancer during renal transplant. Prostate cancer in deceased organ donors has an incidence estimated between 3% and 18.5% and over 100 transplants have been performed using organs from donor with proven prostate cancer without issue. Transmission of prostate cancer through kidney transplantation seems very unlikely. The risks of remaining on the waiting list are outweighed by a transmission risk and the potential benefit makes the case to have clear guidelines about donor prostate malignancy when accepting potential organs.

Evaluation of Kidney Donors: Core Curriculum 2018.

Sawinski, Deirdre; Locke, Jayme E

2018-05-01

Nearly 100,000 patients are waiting for a kidney transplant, yet each year only 11,000 undergo transplantation with a deceased donor kidney. Annual death rates among waitlist registrants range from 5% to 15%; many die before receiving a transplant. Not surprisingly, registrants turn to family and friends to become living kidney donors on their behalf. Living kidney donor selection practices aim to quantify lifetime risk for kidney failure based on a candidate's predonation demographic and health characteristics. It has been established that estimated lifetime risk for kidney failure varies considerably based on predonation comorbid conditions, and as such, it is of paramount importance that potential living donor candidates undergo proper medical, surgical, and psychosocial screening before donation. This installment of AJKD's Core Curriculum in Nephrology provides readers with the tools necessary for proper evaluation of living kidney donor candidates.

Focusing on various phases of the organ donation process, I demonstrate how families and professionals practice hope in astounding ways: when hoping for organs, when hoping for the end of patient suffering, when hoping for the usability of the donor body, and when hoping to help future donor families by sharing painful experiences. By focusing on such practices and transformations of hope, this article sheds light on the social negotiations of life and death among families and staffs in medical contexts and describes how the dignity of the deceased donor and the usability of the donor body are closely connected in family attempts to make donation decisions meaningful during and after a tragic death. © 2016 by the American Anthropological Association.

Constant monitoring is paramount in order to detect the criticalities and improve the results of the deceased donation process. Concomitant with the institution of a regional transplantation service authority--Organizzazione Toscana Trapianti--in 2003, Tuscany adopted a program of quality assurance of the deceased donation process by compulsory reporting of all encephalic deaths from local intensive care units to the regional transplant office in Florence. The indicators we adopted were the efficiency of deceased donor (DD) identification, expressed as the ratio of encephalic deaths (ED) to total deaths with encephalic lesions (EL) (ie, ED/EL); the efficiency of DD reporting, expressed as the ratio of reported potential DD (RPDD) to total ED (ie, RPDD/ED); the efficacy of the DD process, as the ratio between actual DD (ADD) to total ED (ie, ADD/ED); the conversion rate; the percent of opposition to donation; and the incidence of DD maintenance failures. Data were collected prospectively, stratified by regional hospital consortia (Aziende Sanitarie Locali) and compared with international benchmarks. In the period 2003-2006 the mean efficiency of DD identification was 48.3%+/-4.4% (range 42.6%-53.2%); the mean efficiency of DD reporting was 95.2%+/-2.5% (range 92.5%-98.5%); the mean efficacy of the deceased donation process was 51.8%+/-2.4% (range 48.6%-54.4%); the mean conversion rate was 59.6%+/-2.2% (range 57.6%-62.7%); the mean opposition rate was 31.9%+/-1.1% (range 30.6%-33.2%); and the incidence of DD maintenance failure was 5%+/-2.9% (range 2.2%-8.7%). The breakdown analysis revealed wide interhospital variability in terms of efficiency of DD identification (from a low of 25% to a high of 80%); efficacy of the donation process (from a low of 22% to a high of 79%); and conversion rate (from a low of 29% to a high of 79%). Our results highlight that the donation process gets started in about 50% of eligible cases. Further strategies are favored to address this critical area.

Most organ donors are already death. Therefore family members become an essential link in the final decision for organ donation. To get acquainted about the life lessons of people who accepted donating an organ of a deceased family member. Qualitative research, in depth interviews to eight families that accepted donating an organ of a deceased family member. The interviews were analyzed using the method proposed by Streubert et al and modified by Rivera. The life lessons are described in six comprehensive categories. The painful experience changed towards the feeling that the loved one remains alive. This sensation generated a sense of pride in family members and sensitized them towards the painful experience of other people. Therefore, a desire to help and improve as humans beings was awakened. A compassionate approach towards families donating organs with improve organ donation and humanize the process.

A liver for a kidney: Ethics of trans-organ paired exchange.

Living donation provides important access to organ transplantation, which is the optimal therapy for patients with end-stage liver or kidney failure. Paired exchanges have facilitated thousands of kidney transplants and enable transplantation when the donor and recipient are incompatible. However, frequently willing and otherwise healthy donors have contraindications to the donation of the organ that their recipient needs. Trans-organ paired exchanges would enable a donor associated with a kidney recipient to donate a lobe of liver and a donor associated with a liver recipient to donate a kidney. This article explores some of the ethical concerns that trans-organ exchange might encounter including unbalanced donor risks, the validity of informed consent, and effects on deceased organ donation. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

Background and objectives African Americans are disproportionately affected by ESRD, but few receive a living donor kidney transplant. Surveys assessing attitudes toward donation have shown that African Americans are less likely to express a willingness to donate their own organs. Studies aimed at understanding factors that may facilitate the willingness of African Americans to become organ donors are needed. Design, setting, participants, & measurements A novel formative research method was used (the nominal group technique) to identify and prioritize strategies for facilitating increases in organ donation among church-attending African Americans. Four nominal group technique panel interviews were convened (three community and one clergy). Each community panel represented a distinct local church; the clergy panel represented five distinct faith-based denominations. Before nominal group technique interviews, participants completed a questionnaire that assessed willingness to become a donor; 28 African-American adults (≥19 years old) participated in the study. Results In total, 66.7% of participants identified knowledge- or education-related strategies as most important strategies in facilitating willingness to become an organ donor, a view that was even more pronounced among clergy. Three of four nominal group technique panels rated a knowledge-based strategy as the most important and included strategies, such as information on donor involvement and donation-related risks; 29.6% of participants indicated that they disagreed with deceased donation, and 37% of participants disagreed with living donation. Community participants’ reservations about becoming an organ donor were similar for living (38.1%) and deceased (33.4%) donation; in contrast, clergy participants were more likely to express reservations about living donation (33.3% versus 16.7%). Conclusions These data indicate a greater opposition to living donation compared with donation after one’s death among African Americans and suggest that improving knowledge about organ donation, particularly with regard to donor involvement and donation-related risks, may facilitate increases in organ donation. Existing educational campaigns may fall short of meeting information needs of African Americans. PMID:25635038

Living donor kidney transplantation (LDKT) offers better quality of life and clinical outcomes, including patient survival, compared with remaining on dialysis or receiving a deceased donor kidney transplant. Although LDKT education within transplant centers for both potential recipients and living donors is very important, outreach and education to kidney patients in settings other than transplant centers and to the general public is also critical to increase access to this highly beneficial treatment. In June 2014, the American Society of Transplantation’s Live Donor Community of Practice, with the support of 10 additional sponsors, convened a consensus conference to determine best practices in LDKT, including a workgroup focused on developing a set of recommendations for optimizing outreach and LDKT education outside of transplant centers. Members of this workgroup performed a structured literature review, conducted teleconference meetings, and met in person at the 2-day conference. Their efforts resulted in consensus around the following recommendations. First, preemptive transplantation should be promoted through increased LDKT education by primary care physicians and community nephrologists. Second, dialysis providers should be trained to educate their own patients about LDKT and deceased donor kidney transplantation. Third, partnerships between community organizations, organ procurement organizations, religious organizations, and transplant centers should be fostered to support transplantation. Fourth, use of technology should be improved or expanded to better educate kidney patients and their support networks. Fifth, LDKT education and outreach should be improved for kidney patients in rural areas. Finally, a consensus-driven, evidence-based public message about LDKT should be developed. Discussion of the effect and potential for implementation around each recommendation is featured, particularly regarding reducing racial and socioeconomic disparities in access to LDKT. To accomplish these recommendations, the entire community of professionals and organizations serving kidney patients must work collaboratively toward ensuring accurate, comprehensive, and up-to-date LDKT education for all patients, thereby reducing barriers to LDKT access and increasing LDKT rates.

The status of deceased organ donation is assessed using several metrics, including donation/conversion rate (how often at least one organ is recovered for transplant from an eligible death), organ yield (ratio of observed/expected numbers of organs transplanted), and rate of organs discarded (number of organs discarded divided by the number of organs recovered for transplant). The 2012 donation/conversion rate was 72.5. eligible donors per 100 eligible deaths, slightly lower than the 2011 rate but higher than in previous years. The 2011-2012 yield ratio varied by donation service area from 0.91 (fewer organs transplanted per donor than expected) to 1.09 (more than expected), and also varied for specific organs. The mean number of organs transplanted per donor in 2012 was 3.02, lower than in 2011 and 2010; this number varied by donation service area from 2.04 to 3.76. The number of organs discarded is calculated by subtracting the number of organs transplanted from the number recovered for transplant; this number is used to calculate the discard rate. The discard rate in 2012 for all organs combined was 0.14 per recovered organ, slightly higher than in 2011 and 2011; it varied by donation service area and organ type. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

The Organ Procurement and Transplantation Network monitors progress toward strategic goals such as increasing the number of transplants and improving waitlisted patient, living donor, and transplant recipient outcomes. However, a methodology for assessing system performance in providing equity in access to transplants was lacking. We present a novel approach for quantifying the degree of disparity in access to deceased donor kidney transplants among waitlisted patients and determine which factors are most associated with disparities. A Poisson rate regression model was built for each of 29 quarterly, period-prevalent cohorts (January 1, 2010-March 31, 2017; 5 years pre-kidney allocation system [KAS], 2 years post-KAS) of active kidney waiting list registrations. Inequity was quantified as the outlier-robust standard deviation (SD w ) of predicted transplant rates (log scale) among registrations, after "discounting" for intentional, policy-induced disparities (eg, pediatric priority) by holding such factors constant. The overall SD w declined by 40% after KAS implementation, suggesting substantially increased equity. Risk-adjusted, factor-specific disparities were measured with the SD w after holding all other factors constant. Disparities associated with calculated panel-reactive antibodies decreased sharply. Donor service area was the factor most associated with access disparities post-KAS. This methodology will help the transplant community evaluate tradeoffs between equity and utility-centric goals when considering new policies and help monitor equity in access as policies change. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

Urinary tract infection (UTI) is the most common infection posttransplant. However, the risk factors for and the impact of UTIs remain controversial. The aim of this study was to identify the incidence of posttransplant UTIs in a series of renal transplant recipients from deceased donors. Secondary objectives were to identify: (1) the most frequent infectious agents; (2) risk factors related to donor; (3) risk factors related to recipients; and (4) impact of UTI on graft function. This was a retrospective analysis of medical records from renal transplant patients from January to December 2010. Local ethics committee approved the protocol. The incidence of UTI in this series was 34.2%. Risk factors for UTI were older age, (independent of gender), biopsy-proven acute rejection episodes, and kidneys from deceased donors (United Network for Organ Sharing criteria). For female patients, the number of pretransplant pregnancies was an additional risk factor. Recurrent UTI was observed in 44% of patients from the UTI group. The most common infectious agents were Escherichia coli and Klebsiella pneumoniae, for both isolated and recurrent UTI. No difference in renal graft function or immunosuppressive therapy was observed between groups after the 1-year follow-up. In this series, older age, previous pregnancy, kidneys from expanded criteria donors, and biopsy-proven acute rejection episodes were risk factors for posttransplant UTI. Recurrence of UTI was observed in 44%, with no negative impact on graft function or survival. Copyright © 2014 Elsevier Inc. All rights reserved.

The increasing shortage of organs for transplantation has prompted transplant programs to investigate the use of extended criteria donors, such as those with transmissible infectious diseases. Successful cases of organ transplantation (mostly kidney and liver) from Trypanosoma cruzi seropositive donors to seronegative recipients have been reported. We present a case of lung transplantation from a donor serologically positive for Chagas disease to a seronegative recipient, and provide a review of the literature. Left single lung transplantation was performed in a 44-year-old Spanish woman presenting with interstitial lung disease in February 2016. The deceased donor was a Colombian immigrant living in Spain who was serologically positive for Chagas disease. Oral administration of 5 mg/kg/day benznidazole divided in three doses for 60 days was given for specific Chagas disease prophylaxis after transplantation. Periodic follow-up with serological reverse transcription polymerase chain reaction to detect T. cruzi DNA were performed until 6 months after the end of treatment. All results were negative, indicating that transmission of T. cruzi had not occurred. In a review of the literature, two similar cases were identified in Argentina and the United States. In both cases T. cruzi infection was detected posttransplant in the recipients, after which they were treated with benznidazole. The course of the patient described herein confirms that lungs from donors with chronic T. cruzi infection can be used successfully as allografts, and that posttransplant prophylaxis with benznidazole may reduce the probability of transmission of T. cruzi to the recipient.

With a population of >112 million persons, all Mexicans are entitled to receive medical care by the state and more than half have limited access to healthcare. From January 1985 to March 2009, 40 renal transplants were performed from living donors with a high percentage of complications. In April 2009, a new Solid Organ Transplantation Program was started; herein, we present this enterprise to the international community and briefly present a perspective on the Mexican transplant situation. We performed a retrospective chart review of kidney and liver transplant recipients from April 2009 to November 2011, including demographic features, immunosuppression, complications as well as initial and 1 month function. We performed 68 kidney (59 living and 9 deceased donors) and 5 liver transplants (cadaveric donors). The kidney transplant recipients were 73.5% males and showed an overall mean age of 29.77 years (range, 18-60). The donor mean age was 34.08 years. Mean recipient creatinine pretransplant was 13.32 mg/dL, while at day 5 it was 2.33 and at month one, 1.32 mg/dL. Five grafts were lost (7.3%): 4 due to death with a functioning graft and 1 due to acute pyelonephritis. Five patients experienced delayed graft function Basiliximab induction was required in all but one who received thymoglobulin owing to a high panel reactive antibody. Maintenance therapy included a calcineurin inhibitor, mycophenolate mofetil (MMF), and prednisone. Liver transplant recipients were 83.6% women. The etiologies were alcoholic cirrhosis (n = 2), primary billiary cirrhosis (n = 1) and hepatitis C virus infection (n = 2). Complications included: reperfusion syndrome (n = 1), convulsive crisis (medication; n = 1), acute respiratory distress syndrome (n = 1), and death (n = 1). Their Model for End-Stage Liver Disease scopes were 10-21. After basiliximab induction, they had maintenance therapy with tacrolimus, MMF, and steroids. The donor mean age was 26.2 years. All survivors show normal liver function tests currently. From 1985 to 2009, 40 kidney transplants were performed, with multiple complications including donor deaths. Our current results were comparable to international standards, with <15% complication rate. Copyright © 2013 Elsevier Inc. All rights reserved.

AIM To systematically review reports on deceased-donor-lobar lung transplantation (ddLLTx) and uniformly describe size matching using the donor-to-recipient predicted-total lung-capacity (pTLC) ratio. METHODS We set out to systematically review reports on ddLLTx and uniformly describe size matching using the donor-to-recipient pTLC ratio and to summarize reported one-year survival data of ddLLTx and conventional-LTx. We searched in PubMed, CINAHL via EBSCO, Cochrane Database of Systematic Reviews via Wiley (CDSR), Database of Abstracts of Reviews of Effects via Wiley (DARE), Cochrane Central Register of Controlled Trials via Wiley (CENTRAL), Scopus (which includes EMBASE abstracts), and Web of Science for original reports on ddLLTx. RESULTS Nine observational cohort studies reporting on 301 ddLLTx met our inclusion criteria for systematic review of size matching, and eight for describing one-year-survival. The ddLLTx-group was often characterized by high acuity; however there was heterogeneity in transplant indications and pre-operative characteristics between studies. Data to calculate the pTLC ratio was available for 242 ddLLTx (80%). The mean pTLCratio before lobar resection was 1.25 ± 0.3 and the transplanted pTLCratio after lobar resection was 0.76 ± 0.2. One-year survival in the ddLLTx-group ranged from 50%-100%, compared to 72%-88% in the conventional-LTx group. In the largest study ddLLTx (n = 138) was associated with a lower one-year-survival compared to conventional-LTx (n = 539) (65.1% vs 84.1%, P < 0.001). CONCLUSION Further investigations of optimal donor-to-recipient size matching parameters for ddLLTx could improve outcomes of this important surgical option. PMID:28280698

Background Transplant candidate caregivers (TCCs) are an under-utilized but potentially devoted pool of advocates who themselves may be recruited to register for deceased organ donation. Aim To assess and compare recruitment barriers to deceased donor registration efforts in TCCs and health fair attendees (HFAs). Methods A 42-item questionnaire assessing willingness to register as an organ donor and perceptions and knowledge about organ donation was administered to 452 participants (174 in Denver, 278 in San Francisco). Logistic regression, stratified by study site, was used to assess associations between explanatory variables and willingness to register as an organ donor. Results In Denver, 83% of TCCs vs 68% of HFAs indicated a willingness to register (p = 0.03). Controlling for study group (TCC vs HFA), predictors of willingness to register were female gender (OR 2.4), Caucasian race (OR 2.3), college graduate (OR 11.1), married (OR 2.4) and higher positive perception of organ donation (OR 1.2), each p<0.05. In San Francisco, 58% of TCCs vs 70% of HFAs indicated a willingness to register (p = 0.03). Controlling for study group (TCC vs HFA), predictors of willingness to register were Caucasian race (OR 3.5), college graduate (OR 2.2), married (OR 1.9), higher knowledge (OR 1.6) and higher positive perception of organ donation (OR 1.2), each p<0.05. In both locales, Caucasians were more likely to have positive perceptions about organ donation and were more willing to register. Conclusions Demographic characteristics, not personal connection to a transplant candidate, explain willingness to register as an organ donor. PMID:24519521

Renal transplantation represents the treatment of choice of end-stage kidney disease. Delayed graft function (DGF) remains the most frequent complication after this procedure, reaching more than 30%. Its prevention is essential as it impedes early- and long-term prognosis of transplantation. Numerous pharmacological interventions aiming to prevent ischemia-reperfusion injuries failed to reduce the rate of DGF. We hypothesize that cyclosporine as an early preconditioning procedure in donors would be associated with decreased DGF. The Cis-A-rein study is an investigator-initiated, prospective, multicenter, double-blind, randomized, controlled study performed to assess the effects of a donor preconditioning with cyclosporine A on kidney grafts function in transplanted patients. After randomization, a brain dead donor will receive 2.5 mg kg -1 of cyclosporine A or the same volume of 5% glucose solution. The primary objective is to compare the rate of DGF, defined as the need for at least one dialysis session within the 7 days following transplantation, between both groups. The secondary objectives include rate of slow graft function, mild and severe DGF, urine output and serum creatinine during the first week after transplantation, rate of primary graft dysfunction, renal function and mortality at 1 year. The sample size (n = 648) was determined to obtain 80% power to detect a 10% difference for rate of DGF at day 7 between the two groups (30% of the patients in the placebo group and 20% of the patients in the intervention group). Delayed graft function is a major issue after renal transplantation, impeding long-term prognosis. Cyclosporine A pretreatment in deceased donors could improve the outcome of patients after renal transplantation. ClinicalTrials.gov, ID: NCT02907554 Registered on 20 September 2016.

Relaxing the standard lung donor criteria may significantly increase the reported 15% organ yield but post-transplant recipient outcome should be carefully monitored. Charts from all consecutive deceased organ donors within our hospital network were reviewed over a 2-year period. Reasons for lung refusals and number of lungs transplanted were analysed. Hospital outcome including early recipient survival was compared between standard- and extended criteria donors. Out of 283 referrals, 164 (58%) qualified as donor of any organ. The majority (65.9%) of these effective donors were declined for lung donation because of chest X-ray abnormalities (20%), age >70 years (13%), poor oxygenation (10%), or aspiration (9%). Out of 56 (34.1%) accepted lung donors, 50 transplants were performed at our center, 23 from standard criteria donors versus 27 from extended criteria donors. There were no significant differences in hospital outcome and in early survival between lung recipients from both donor groups. Lung acceptance rate (34.1%) in our donor network is 10-20% higher than reported figures. The number of lung transplants in our center doubled by accepting extended criteria donors. This policy did not negatively influence our results after lung transplantation.

The objectives of this review are to introduce and explore the following representative ethical problems generated by modern renal replacement therapy: (1) reviewing the historical origin of medical ethics with specific reference to nephrology; (2) recognizing the complex stresses surrounding assignment of a deceased donor renal transplant to a geriatric patient while young patients continue waiting for a donor kidney; and (3) appreciating the concept of futility and support for a uremic patient opting for death rather than further uremia therapy as the best in choice in coping with renal failure.

Background: Canada has low rates of deceased organ and tissue donation. Immigrants to Canada may differ in their registered support for deceased organ donation based on their country of origin. Methods: We used linked administrative databases in Ontario (about 11 million residents aged ≥ 16 yr) to study the proportion of immigrants and long-term residents registered for deceased organ and tissue donation as of October 2013. We used modified Poisson regression to identify and quantify predictors of donor registration. Results: Compared with long-term residents (n = 9 244 570), immigrants (n = 1 947 646) were much less likely to register for deceased organ and tissue donation (11.9% v. 26.5%). Immigrants from the United States, Australia and New Zealand had the highest registration rate (40.0%), whereas immigrants with the lowest registration rates were from Eastern Europe and Central Asia (9.4%), East Asia and Pacific (8.4%) and sub-Saharan Africa (7.9%). The largest numbers of unregistered immigrants were from India (n = 202 548), China (n = 186 678) and the Philippines (n = 125 686). Characteristics among the immigrant population associated with a higher likelihood of registration included economic immigrant status, living in a rural area (population < 10 000), living in an area with a lower ethnic concentration, less material deprivation, a higher education, ability to speak English and French, and more years residing in Canada. Interpretation: Immigrants in Ontario were less likely to register for deceased organ and tissue donation than long-term residents. There is a need to better understand reasons for lower registration rates among Canadian immigrants and to create culture-sensitive materials to build support for deceased organ and tissue donation.

Explainable variation in renal transplant outcomes: a comparison of standard and expanded criteria donors.

PubMed

Gjertson, David W

2004-01-01

In 2002, OPTN/UNOS altered kidney allocation rules to allow patients to be listed separately to receive kidneys from expanded criteria donors (ECD). Our aim was to quantify the short- and long-term impacts of 21 prognostic factors on recipients of ECD as well as recipients of living (LD) and deceased standard criteria (SCD) donors. A factor's impact depends on both the risk and diversity of its effects. Using OPTN/UNOS Registry data from 1996-2003, we have analyzed kidney-only, adult-recipient grafts for factor effects among 35,878 LD, 47,941 SCD and 10,399 ECD transplants. During an early risk period, all 94,218 recipients were followed through one year, and, in the late risk period, 85,270 recipients whose grafts survived beyond one year were followed for 5 years post-transplant. Impact was measured by determining a factor's percentage of assignable variation in one- and 5-year graft failure rates. Scores for 21 factors were estimated via generalized logistic models, which contained a random component for transplant center. The assignable variation associated with a given factor was computed as the factor score variance multiplied by the square of the corresponding regression coefficient. Impacts were heterogeneous with regard to posttransplant period and donor type. The top 5 factors influencing one-year graft survival rates were as follows: * For LD grafts - pretransplant dialysis time (14% of the variation in short-term outcomes), recipient age (13%), body mass (12%), PRA (10%) and induction therapy (10%). * For SCD grafts - donor age (24%), recipient age (12%), pretransplant dialysis time (12%), HLA-DR matching (6%) and pretransplant medical condition (6%). * For ECD grafts - donor age (18%), pre-transplant dialysis time (10%), recipient age (10%), pretransplant medical condition (10%) and recipient body mass (6%). Ranking long-term outcomes demonstrated the following top 5 influential factors: * For LD grafts - donor age (28% of the variation in long-term outcomes), recipient race (15%), age (15%), transplant year (13%) and recipient sex (11%). * For SCD grafts - donor age (35%), recipient race (23%), transplant year(15%), recipient sex (8%)and age (5%). * For ECD grafts - donor age (33%), recipient sex (20%), race (15%), transplant year (8%) and recipient's original disease (5%). Donor age was the dominant factor governing the survival rates among deceased donor kidney transplants. Advancing donor age was still the major risk factor for SCD transplant failure despite setting aside all donors 60 and up, and a large fraction of 50-59 year-old donors, from this group. Current ECD/SCD definitions warrant review and possible revision.

Despite the advantages of living donor transplantation, evidence suggests that some potential recipients with living donors have psychological concerns that prevent them from pursuing living donation. Addressing these concerns through education may increase the rates of living donation. To understand the psychological barriers and educational needs of potential kidney recipients regarding living donation. Qualitative focus group study of kidney transplant recipients, donors, and family members to explore their assessment of the advantages of dialysis and deceased donor transplantation over living donation, their concerns about living donation, and what types of living donation education would be most helpful. Kidney recipients reported that they might not pursue living donation because they felt guilty and indebted to the donor, did not want to harm or inconvenience the donor, did not want to accept a kidney that a family member might need later, and did not want to disappoint the donor if the kidney failed. Recipients were generally unaware that donors could personally benefit from donating and would rather wait for donor volunteers than ask anyone directly. Both donors and recipients thought that training on how to make the donation request and education about living donors' motivations for donation and transplant experience could help more renal patients pursue living donation.

Efforts to increase the dismal deceased renal transplantation (DRT): live renal transplantation (LRT) ratio in our country have gathered momentum recently, with governmental and non-governmental projects focussing on building public awareness and capacity-building, and appropriate legislation. Worldwide, efforts at increasing the number of organs from the deceased pool have focussed on the use of 'expanded criteria donors', including deceased cardiac donors (DCD). 'Reuse' transplant, where an organ is transplanted after removal from the first recipient, is a rare strategy, used more commonly in liver than in kidney transplantation. Exceptional circumstances, where other organs have been harvested from transplant recipients, are rare. We describe the successful transplants of two renal grafts obtained from a 19-year-old brain-dead liver transplant recipient; this is probably the second case in English-language literature. A 19-year-old male patient with hepatitis E-induced fulminant hepatic failure underwent live-related liver transplantation. On postoperative day 2, cerebral edema set in, and the patient was declared brain-dead. Despite the economical and emotional trauma, the family opted for donation of the well-perfused kidneys. The kidneys were transported in HTK solution (histidine-tryptophan-ketoglutarate) to our centre. Recipient 1 was a 32-year-old woman (B positive) and recipient 2 was a 29-year-old man (also B positive); the kidneys were placed extraperitoneally and anastomosed end-to-side to the external iliac artery and vein. Recipient 2 experienced delayed graft function; however, both are doing well 15 months posttransplant.

Understanding the three-dimensional (3D) nature of the human form is imperative for effective medical practice and the emergence of 3D printing creates numerous opportunities to enhance aspects of medical and healthcare training. A recently deceased, un-embalmed donor was scanned through high-resolution computed tomography. The scan data underwent segmentation and post-processing and a range of 3D-printed anatomical models were produced. A four-stage mixed-methods study was conducted to evaluate the educational value of the models in a medical program. (1) A quantitative pre/post-test to assess change in learner knowledge following 3D-printed model usage in a small group tutorial; (2) student focus group (3) a qualitative student questionnaire regarding personal student model usage (4) teaching faculty evaluation. The use of 3D-printed models in small-group anatomy teaching session resulted in a significant increase in knowledge (P = 0.0001) when compared to didactic 2D-image based teaching methods. Student focus groups yielded six key themes regarding the use of 3D-printed anatomical models: model properties, teaching integration, resource integration, assessment, clinical imaging, and pathology and anatomical variation. Questionnaires detailed how students used the models in the home environment and integrated them with anatomical learning resources such as textbooks and anatomy lectures. In conclusion, 3D-printed anatomical models can be successfully produced from the CT data set of a recently deceased donor. These models can be used in anatomy education as a teaching tool in their own right, as well as a method for augmenting the curriculum and complementing established learning modalities, such as dissection-based teaching.

Microbiological screening of tissue allografts is crucial to prevent the transmission of bacterial and fungal infections to transplant recipients. Klebsiella was the most prevalent and resistant contaminating microorganism observed in our setting in the Iranian Tissue Bank. This study was conducted to determine the presence of extended-spectrum β-lactamase (ESBL) genes, antimicrobial resistance patterns of Klebsiella pneumoniae isolates, and their clonal relationships in allograft materials. K. pneumoniae contaminating bone and other tissue allografts recovered from deceased donors were identified and ESBL isolates were detected using a phenotypic confirmatory method. Antimicrobial susceptibility testing was carried out using the disk diffusion method. Distribution of ESBL genes and molecular typing were performed using polymerase chain reaction (PCR) and Repetitive-element (rep-PCR) methods. Of 3828 donated tissues, 51 (1.3%) were found contaminated by K. pneumoniae isolates. Compared to tissue allografts from brain-dead, heart-beating tissue donors, allografts from donors with circulatory cessation were associated with a higher risk of K. pneumoniae contamination [odds ratio (OR), 1.2 (CI 95% 0.9-2.3) (P value < 0.001)]. Half of the isolates produced ESBL, and the rate of susceptibility to cephalosporins was 51%. Among isolates, 22 (43.1%) harbored CTX-M, 31 (60.8%) SHV, and 9 (17.6%) harbored TEM types. The rep-dendrogram indicated that clones having identical or related strains with a similar antibiotype were isolated in the same period. This study provides evidence that a single clone of K. pneumoniae contaminated tissue allografts recovered from many different donors. A single clone found on tissues from several donors suggests contamination of tissues from a single source such as the tissue recovery process and environment. Genomic DNA testing and clonality of contaminating bacteria using molecular methods can focus the epidemiologic investigation on the tissue allograft recovery process including a search for contamination of the tissue recovery room environment, recovery staff, recovery equipment, reagents, solutions and supplies.

The desire to provide cost-effective care has lead to an investigation of the costs of therapy for end-stage renal disease. Organ quality metrics are one way to attempt to stratify kidney transplants, although the ability of these metrics to predict costs and resource use is undetermined. The Scientific Registry of Transplant Recipients database was linked to the University HealthSystem Consortium Database to identify adult deceased donor kidney transplant recipients from 2009 to 2012. Patients were divided into cohorts by kidney criteria (standard vs expanded) or kidney donor profile index (KDPI) score (<85 vs 85+). Length of stay, 30-day readmission, discharge disposition, and delayed graft function were used as indicators of resource use. Cost was defined as reimbursement based on Medicare cost/charge ratios and included the costs of readmission when applicable. More than 19,500 patients populated the final dataset. Lower-quality kidneys (expanded criteria donor or KDPI 85+) were more likely to be transplanted in older (both P < .001) and diabetic recipients (both P < .001). After multivariable analysis controlling for recipient characteristics, we found that expanded criteria donor transplants were not associated with increased costs compared with standard criteria donor transplants (risk ratio [RR] 0.97, 95% confidence interval [CI] 0.93-1.00, P = .07). KDPI 85+ was associated with slightly lower costs than KDPI <85 transplants (RR 0.95, 95% CI 0.91-0.99, P = .02). When KDPI was considered as a continuous variable, the association was maintained (RR 0.9993, 95% CI 0.999-0.9998, P = .01). Organ quality metrics are less influential predictors of short-term costs than recipient factors. Future studies should focus on recipient characteristics as a way to discern high versus low cost transplantation procedures. Copyright © 2015 Elsevier Inc. All rights reserved.

To evaluate if living donor liver transplantation (LDLT) should be offered to patients with Model for End-stage Liver Disease (MELD) scores ≥35. No data was available to support LDLT of such patients. Data of 672 consecutive adult liver transplant recipients from 2005 to 2014 at our center were reviewed. Patients with MELD scores ≥35 were divided into the deceased donor liver transplantation (DDLT) group and the LDLT group and were compared. Univariate analysis was performed to identify risk factors affecting survival. The LDLT group (n = 54) had younger (33 yrs vs 50 yrs, P < 0.001) and lighter (56 Kg vs 65 Kg, P = 0.004) donors, lighter grafts (627.5 g vs 1252.5 g, P < 0.001), lower graft-weight-to-recipient-standard-liver-volume rates (51.28% vs 99.76%, P < 0.001), shorter cold ischemic time (106.5 min vs 389 min, P < 0.001), and longer operation time (681.5 min vs 534 min, P < 0.001). The groups were comparable in postoperative complication, hospital mortality, and graft survival and patient survival at one year (88.9% vs 92.5%; 88.9% vs 94.7%), three years (87.0% vs 86.9%; 87.0% vs 88.8%), and five years (84.8% vs 81.8%; 84.8% vs 83.3%). Univariate analysis did not show inferior survival in LDLT recipients. At centers with experience, the outcomes of LDLT can be comparable with those of DDLT even in patients with MELD scores ≥35. When donor risks and recipient benefits are fully considered and balanced, an MELD score ≥35 should not be a contraindication to LDLT. In Hong Kong, where most waitlisted patients have acute-on-chronic liver failure from hepatitis B, LDLT is a wise alternative to DDLT.

Deceased donor liver transplant (DDLT) is an uncommon procedure in India. We present our experience of DDLT from a public sector teaching hospital. A retrospective analysis of all DDLT was performed from April 2012 till September 2016. Demographics, intraoperative, donor factors, morbidity, and outcome were analyzed. During the study period, 305 liver transplants were performed, of which 36 were DDLT (adult 32, pediatric 4; 35 grafts; 1 split). The median age was 42.5 (1-62) years; 78% were men. The median donor age was 28 (1-77) years; 72.2% were men. About 45% of organs were procured from outside of Delhi and 67% of all grafts used were marginal. Three of 38 liver grafts (7.8%) were rejected due to gross steatosis. Commonest indication was cryptogenic cirrhosis (19.4%). The median model for end-stage liver disease sodium and pediatric end-stage liver disease scores were 23.5 (9-40) and 14.5 (9-22), respectively. Median warm and cold ischemia times were 40 (23-56) and 396 (111-750) min, respectively. Major morbidity of grade III and above occurred in 63.8%. In hospital (90 days), mortality was 16.7% and there were two late deaths because of chronic rejection and biliary sepsis. The overall survival was 77.8% at median follow up of 8.6 (1-54) months. DDLT can be performed with increasing frequency and safety in a public sector hospital. The perioperative and long-term outcomes are acceptable despite the fact that most organs were extended criteria grafts.

Short- and intermediate-term results have been reported after rapid discontinuation of prednisone (RDP) in kidney transplant recipients. Yet there has been residual concern about late graft failure in the absence of maintenance prednisone. From October 1, 1999, through June 1, 2015, we performed a total of 1553 adult first and second kidney transplants-1021 with a living donor, 532 with a deceased donor-under our RDP protocol. We analyzed the 15-year actuarial overall patient survival (PS), graft survival (GS), death-censored GS (DCGS), and acute rejection-free survival (ARFS) rates for RDP compared with historical controls on maintenance prednisone. For living donor recipients, the actuarial 15-year PS rates were similar between groups. But RDP was associated with increased GS (P = 0.02) and DCGS (P = 0.01). For deceased donor recipients, RDP was associated with significantly better PS (P < 0.01), GS (P < 0.01) and DCGS (P < 0.01). There was no difference between groups in the rate of acute or chronic rejection, or in the mean estimated glomerular filtration rate at 15 years. However, RDP-treated recipients had significantly lower rates of avascular necrosis, cytomegalovirus, cataracts, new-onset diabetes after transplant, and cardiac complications. Importantly, for recipients with GS longer than 5 years, there was no difference between groups in subsequent actuarial PS, GS, and DCGS. In summary, at 15 years postkidney transplant, RDP did not lead to decreased in PS or GS, or an increase in graft dysfunction but as associated with reduced complication rates.

Patients considering renal transplantation face an increasingly complex array of choices as a result of the revised kidney transplant allocation system. Decision aids have been shown to improve patient decision-making through the provision of detailed, relevant, individualized clinical data. A mobile iOS-based application (app) including animated patient education and individualized risk-adjusted outcomes following kidney transplants with varying donor characteristics and DSA waiting times was piloted in two large US transplant programs with a diverse group of renal transplant candidates (N = 81). The majority (86%) of patients felt that the app improved their knowledge and was culturally appropriate for their race/ethnicity (67%-85%). Patients scored significantly higher on transplant knowledge testing (9.1/20 to 13.8/20, P < .001) after viewing the app, including patients with low health literacy (8.0 to 13.0, P < .001). Overall knowledge of and interest in living and deceased donor kidney transplantation increased. This pilot project confirmed the benefit and cultural acceptability of this educational tool, and further refinement will explore how to better communicate the risks and benefits of nonstandard donors. © 2017 John Wiley & Sons A/S.

This study compared the use of static cold storage versus continuous hypothermic machine perfusion in a cohort of kidney transplant recipients at high risk for delayed graft function (DGF). In this national, multicenter, and controlled trial, 80 pairs of kidneys recovered from brain-dead deceased donors were randomized to cold storage or machine perfusion, transplanted, and followed up for 12 months. The primary endpoint was the incidence of DGF. Secondary endpoints included the duration of DGF, hospital stay, primary nonfunction, estimated glomerular filtration rate, acute rejection, and allograft and patient survivals. Mean cold ischemia time was high but not different between the 2 groups (25.6 ± 6.6 hours vs 25.05 ± 6.3 hours, 0.937). The incidence of DGF was lower in the machine perfusion compared with cold storage group (61% vs. 45%, P = 0.031). Machine perfusion was independently associated with a reduced risk of DGF (odds ratio, 0.49; 95% confidence interval, 0.26-0.95). Mean estimated glomerular filtration rate tended to be higher at day 28 (40.6 ± 19.9 mL/min per 1.73 m 2 vs 49.0 ± 26.9 mL/min per 1.73 m 2 ; P = 0.262) and 1 year (48.3 ± 19.8 mL/min per 1.73 m 2 vs 54.4 ± 28.6 mL/min per 1.73 m 2 ; P = 0.201) in the machine perfusion group. No differences in the incidence of acute rejection, primary nonfunction (0% vs 2.5%), graft loss (7.5% vs 10%), or death (8.8% vs 6.3%) were observed. In this cohort of recipients of deceased donor kidneys with high mean cold ischemia time and high incidence of DGF, the use of continuous machine perfusion was associated with a reduced risk of DGF compared with the traditional cold storage preservation method.

New Zealand is a geographically isolated country with 4.55 million inhabitants. It has endemic hepatitis B (HBV) infection that is especially evident in Maori and Pacific Island communities and impacts indications for liver transplantation. The country has a socialised medical system that allows for full coverage of the assessment for, and completion of liver transplants in suitable recipients. Between February 1998 and December 2014, the New Zealand Liver Transplant Unit (NZLTU) had performed 595 liver transplants in 568 patients, indicating a crude re-transplant rate of 4.8%. Overall 1, 5, and 10 year patient survival rates for all adult (96%, 89%, and 81%, respectively) and pediatric (93%, 92%, and 92%, respectively) recipients compare very favourably with international outcomes from Europe and the United States. Eligibility criteria could be modestly expanded if deceased donor rates improved from the current level of around 10 per million of population per year. This somewhat meagre supply of deceased donor organs, along with significant waiting list attrition, has necessitated the use of living donors, which have been used in more than 50 recipients to date. Despite these limitations, the NZLTU has contributed to improvements in the outcome of transplantation for HBV and hepatitis C through the development of effective antiviral prophylaxis regimes. Furthermore, innovative changes have been made to the manner in which pediatric patients are transitioned to the adult service.

Organ transplantation in Tunisia.

Kidney transplants were first performed in Tunisia in 1986, and transplants soon extended to other organs including the heart, liver, and pancreas. Live-related donor and deceased-donor kidney transplants were both began in the summer of 1986. An organ procurement and transplant law was passed in March 1991, and the National Centre for Advancement of Organ Transplantation was created in 1995. The number of transplantation units has increased to 7 throughout the country, and the yearly transplant number has progressively increased to 139 in 2010, including 20% from deceased kidney donors. Despite these gains, the need continues to grow. Heart transplants began in January 1993, and Tunisia and Jordan are currently the only Arab countries where it is practiced. However, only 16 patients have received a heart transplant as of 2004, and the number of recipients has decreased in the past 10 years. Liver transplants are rare in other Arab countries, but began in Tunisia in January 1998. Over 10 years, 38 patients benefited from this procedure. After a few years of stagnation, the number of liver transplants is increasing. While all types of transplantation are needed, kidney transplantation is a priority in Tunisia. The target is to perform 400 transplants annually, which would require a long-term strategy to provide full financial coverage using the National Health Insurance Funds in both the public and private sectors.

The Liver Match is an observational cohort study that prospectively enrolled liver transplantations performed at 20 out of 21 Italian Transplant Centres between June 2007 and May 2009. Aim of the study is to investigate the impact of donor/recipient matching on outcomes. In this report we describe the study methodology and provide a cross-sectional description of donor and recipient characteristics and of graft allocation. Adult primary transplants performed with deceased heart-beating donors were included. Relevant information on donors and recipients, organ procurement and allocation were prospectively entered in an ad hoc database within the National Transplant Centre web-based Network. Data were blindly analysed by an independent Biostatistical Board. The study enrolled 1530 donor/recipient matches. Median donor age was 56 years. Female donors (n = 681, median 58, range 12-92 years) were older than males (n = 849, median 53, range 2-97 years, p < 0.0001). Donors older than 60 years were 42.2%, including 4.2% octogenarians. Brain death was due to non-traumatic causes in 1126 (73.6%) cases. Half of the donor population was overweight, 10.1% was obese and 7.6% diabetic. Hepatitis B core antibody (HBcAb) was present in 245 (16.0%) donors. The median Donor Risk Index (DRI) was 1.57 (>1.7 in 35.8%). The median cold ischaemia time was 7.3h (≥ 10 in 10.6%). Median age of recipients was 54 years, and 77.7% were males. Hepatocellular carcinoma (HCC) was the most frequent indication overall (44.4%), being a coindication in roughly 1/3 of cases, followed by viral cirrhosis without HCC (28.2%) and alcoholic cirrhosis without HCC (10.2%). Hepatitis C virus infection (with or without HCC) was the most frequent etiologic factor (45.9% of the whole population and 71.4% of viral-related cirrhosis), yet hepatitis B virus infection accounted for 28.6% of viral-related cirrhosis, and HBcAb positivity was found in 49.7% of recipients. The median Model for End Stage Liver Disease (MELD) at transplant was 12 in patients with HCC and 18 in those without. Multivariate analysis showed a slight but significant inverse association between DRI and MELD at transplant. The deceased donor population in Italy has a high-risk profile compared to other countries, mainly due to older donor age. Almost half of the grafts are transplanted in recipients with HCC. Higher risk donors tend to be preferentially allocated to recipients with HCC, who are usually less ill and older. No other relevant allocation strategy is currently adopted at national level.

Beyond the Billboard: The Facebook-Based Application, Donor, and Its Guided Approach to Facilitating Living Organ Donation.

PubMed

Bramstedt, K A; Cameron, A M

2017-02-01

Living donor solicitation can raise ethical concerns, regardless of the medium used: newspaper, television, pulpit, billboard or Internet. Moving the search for a living donor into the social media realm introduces the risk of unguided and coercive patient narratives as well as decoupling or even total absence of information that could aid the consent process. The Facebook application (app) for living donors, called Donor (restricted to patient use), aims to address these concerns in several ways: (i) by directing the patient's initial appeal to friends and family; (ii) by guiding the patient's narrative; and (iii) by providing a library of clinical, ethical and regulatory information that informs the consent process. In this paper, we explored these features and contrasted them with billboard solicitation activities and current independent social media efforts. We concluded that the proactive ethical design of the Donor app is a permissible way to help satisfy the shortfall of deceased donor livers and kidneys. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

Sharing organs with foreign nationals.

PubMed

Bruni, Rebecca; Wright, Linda

2011-03-01

Organs for transplantation are an absolute scarcity throughout the world, and many countries do not offer transplantation. Developed countries with transplant programs receive requests to list foreign nationals for transplantation. Any national standard deserves justification by a thorough exploration of the issues. In this article, the issues regarding organ transplantation for foreign nationals in Canada are explored. Currently Canada has no policy on listing foreign nationals for transplantation. Three topics are reviewed: (1) arguments for and against the transplantation of organs from deceased donors to foreign nationals, (2) relevant legislation and position statements, and (3) relevant practices in other countries. Finally, practical policy options are suggested. This article's analysis of the issues will provide guidance for health care professionals and policy makers in Canada and developed countries exploring listing foreign nationals for transplantation.

The aim of this study was to describe the epidemiology and utilization of anti-hepatitis B core protein(+) and anti-hepatitis C virus(+) organ donor referrals in a large organ procurement organization. Between 1995 and 2006, 3,134 deceased organ donor referrals were tested for anti-HBc and anti-HCV using commercial assays. The prevalence of anti-HCV(+) organ donor referrals significantly increased from 3.4% in 1994-1996 to 8.1% in 2003-2005 (P < .001), whereas the prevalence of anti-HBc(+) organ donor referrals remained unchanged at 3%-4% (P = .20). The 112 anti-HBc(+) (3.5%) and 173 anti-HCV(+) (5.5%) organ donor referrals were significantly older and more likely to be noncaucasian than seronegative organ donor referrals (P < .02). The procurement and utilization rates of seropositive thoracic and abdominal donor organs were significantly lower compared with seronegative organ donors (P < .0001). However, liver utilization rates significantly increased from anti-HBc(+) donors over time (21% vs 46%; P = .026), whereas utilization of anti-HCV(+) liver donors remained unchanged over time (5% vs 18%; P = .303). In summary, the proportion of anti-HCV(+) organ donor referrals has significantly increased and the proportion of anti-HBc(+) organ donor referrals has remained stable. Both thoracic and abdominal organs from seropositive donors are largely underutilized. Copyright © 2010 Elsevier Inc. All rights reserved.

Religious aspects of organ transplantation.

PubMed

Bruzzone, P

2008-05-01

No religion formally forbid donation or receipt of organs or is against transplantation from living or deceased donors. Only some orthodox jews may have religious objections to "opting in." However, transplantation from deceased donors may be discouraged by Native Americans, Roma Gypsies, Confucians, Shintoists, and some Orthodox rabbis. Some South Asia Muslim ulemas (scholars) and muftis (jurists) oppose donation from human living and deceased donors because the human body is an "amanat" (trusteeship) from God and must not be desecrated following death, but they encourage xenotransplantation research. No religion formally obliges one to donate or refuse organs. No religion formally obliges one to consider cadaveric organs "a societal resource" or considers organ donation "a religious duty" (except some rabbis and isolated Muslim and Christian scholars) No religion has a formal position on "bonus points," which is priority on the waiting list. Living organ donation is strongly encouraged only between jesus christians (15 of 28 jesus christians worldwide have donated a kidney). No religion forbid this practice. Directed organ donation to people of the same religion has been proposed only by some Orthodox Jews and some Islamic Ulemas/Muftis. Only some Muslim Ulemas/Muftis and some Asian religions may prefer living donation over cadaveric donation. No religion prefers cadaveric over living donation. No religion formally forbid non-heart-beating donors (nhbd) cadaveric donation or cross-over donation. Due to the sacrad of human life, the Catholic Church is against donation from anencephalic donors or after active euthanasia. No religion formally forbid xenotransplantation. Addressing the participants of the First International Congress of the Society for Organ Sharing in 1991, Pope John Paul II said "There are many questions of an ethical, legal and social nature which need to be more deeply investigated. There are even shameful abuses which call for determined action on the part of medical association and donor societies, and especially of competent legislative bodies" and later on "In effect, the human body is always a personal body, the body of a person. The body cannot be treated as a merely physical or biological entity, nor can its organs and tissues ever be used as item for sale or exchange". Addressing the participants at the XVIII International Congress of the Transplantation Society in 2000, Pope John Paul II said "Accordingly, any procedure which tends to commercialize human organs or to consider them as items of exchange or trade must be considered morally unacceptable, because to use the body as an object is to violate the dignity of the human person" and later on added "The criteria for assigning donated organs should in no way be discriminatory (i.e. based on age, sex, race, religion, social standing, etc.) or utilitarian (i.e. based on work capacity, social usefulness, etc.)." To conclude, according to the Catechism of the Catholic Church Compendium signed by Pope Benedict XVI on june 28, 2005, 476. Are allowed transplantation and organ donation, before and after death? Organ transplantation is morally acceptable with the consent of the donor and without excessive risks for him/her. For the noble act of organ donation after death, the real death of the donor must be fully ascertained.

Advances in Ethical, Social, and Economic Aspects of Chronic Renal Disease in Bolivia.

Since 2005, great progress has been made in health care provision to patients with terminal renal failure in Bolivia. Access to dialysis and transplantation is regulated by the Ministry of Health, based on clinical criteria, applied equitably, without favoritism or discrimination based on race, sex, economic means, or political power. Until December 2013, there were no restrictions in dialysis and transplantation in Health Insurance institutions, but they covered only 30% of the population. Now the remaining 70% has access to free dialysis funded by the communities where patients live, with funds coming from the government and taxes on oil products. More than 2,231 people are getting dialysis, reaching a population growth of >60% annually. The number of hemodialysis units has increased by >200% (60 units), making access easier for end-stage renal failure patients. Treatment protocols have been drawn up to guarantee the best quality of life for the patients. The Law on Donation and Transplantation was enacted in 1996, and Supplementary Regulations were enacted in 1997 with various amendments over the past 5 years. A National Transplant Coordination Board, working under the National Renal Health Program, supervises and regulates transplants and promotes deceased-donor transplantation in an attempt to cover the demand for donors. Rules have been drawn up for accreditation of transplant centers and teams to guarantee the best possible conditions and maximum guaranties. Since January 2014, the National Renal Health Program has been providing free kidney transplants from living donors. Copyright © 2016 Elsevier Inc. All rights reserved.

Ethical issues in organ and tissue transplantation.

PubMed

Abouna, George M

2003-12-01

Clinical organ transplantation provides a way of giving the gift of life to patients with terminal failure of vital organs, which requires the participation of other fellow human beings and of society by donating organs from deceased or living individuals. The increasing incidence of vital organ failure and the inadequate supply of organs, especially from cadavers, has created a wide gap between organ supply and organ demand, which has resulted in very long waiting times to receive an organ as well as an increasing number of deaths while waiting. These events have raised many ethical, moral and societal issues regarding supply, the methods of organ allocation the use of living donors as volunteers including minors. It has also led to the practice of organ sale by entrepreneurs for financial gains in some parts the world through exploitation of the poor, for the benefit of the wealthy. The current advances in immunology and tissue engineering and the use of animal organs, xenotransplantation, while offering very promising solutions to many of these problems, also raise additional ethical and medical issues, which must be considered by the medical profession as well as society. This review deals with the ethical and moral issues generated by the current advances in organ transplantation, the problem of organ supply versus organ demand and the appropriate allocation of available organs. It deals with the risks and benefits of organ donation from living donors, the appropriate and acceptable methods to increase organ donation from the deceased through the adoption of the principle of 'presumed consent', the right methods of providing acceptable appreciation and compensation for the family of the deceased as well as volunteer and altruistic donors, and the duties and responsibilities of the medical profession and society to help fellow humans. The review also deals with the appropriate and ethically acceptable ways of utilizing the recent advances of stem cell transplantation from adult versus fetal donors, tissue engineering and the use of organs from animals or xenotransplantation. It is emphasized that clinical organ and tissue transplantation can be more beneficial and life saving if everyone involved in the process, including physicians and medical institutions, respect and consider the best interests of the patients, as well as honor the ethical, moral and religious values of society.

Malaysians indicating that they did not intend to become organ donors upon their death were surveyed regarding interest in non-fungible financial incentives to be granted to surviving family members. Among the 730 (56% of the total sample of 1311) indicating unwillingness to be donors, 29.6% (216/730) subsequently indicated that they would be willing donors if the government introduced policies that, upon their death, "rewarded your (their) family with incentives for your (their) deeds." Among the 69% (504/730) who insisted that they would not become organ donor even with incentive, nearly 80% (404/501) of them were able to identify relevant incentives they thought should be provided by the state to those who make organ donations upon death. The majority of both groups preferred the state provide medical benefits to a surviving family member, suggesting this may be an attractive policy option for the state to raise the deceased organ donation pool. © 2013 John Wiley & Sons A/S.

The organ transplantation act and recent trends in Korea.

PubMed

Joo, Ho No

2013-03-01

The Organ Transplantation Act, including transplantation of organs from brain-dead donors, entered into force in Korea on February 9, 2000. This article introduces the Organ Transplantation Act, focusing on scope of the Act, determination of brain death, removal of organs from brain-dead or deceased donors, removal from living donors, organ allocation, and prohibition of trade in human organs. Especially, some primary ethical dilemmas surrounding organ allocation arise from the shortage of available organs. The primary ethical problems surrounding organ allocation are as follows. A key purpose of the organ donation incentive system is to increase the number of organ transplants from brain-dead donors. In particular, the priority for kidney patient was allowed in consideration of doctor's strong desire to increase the brain-dead donors. Also, the organ allocation criteria based on the organ donation incentive system appear unfair, especially for the kidney patient, because the criteria do not fit the principles of distributive justice. In the future, the organ donation incentive system itself may need to be reexamined.

Four years of experience with the Australian kidney paired donation programme.

PubMed

Cantwell, Linda; Woodroffe, Claudia; Holdsworth, Rhonda; Ferrari, Paolo

2015-03-01

New approaches to increase kidney transplantation rates through expansion of live donor kidney transplantation have become necessary due to ongoing shortage of deceased donor organs. These strategies include desensitization in antibody-incompatible transplants to overcome the barrier of blood group incompatibility or human leucocyte antigen antibodies between recipient and donor and kidney paired donation (KPD) programmes. In KPD, a kidney transplant candidate with an incompatible live donor joins a registry of other incompatible pairs in order to find potentially compatible transplant solutions. To match the largest possible number of donor-recipient pairs while minimizing immunologic risk, KPD programmes use sophisticated algorithms to identify suitable matches with simultaneous two-way or more complex multi-way exchanges as well as including non-directed anonymous donors to start a chain of compatible transplantations. Because of the significant immunologic barriers when fewer donor options are available, the optimal solution for difficult-to-match, highly sensitized patients is access to more potential donors using large multi-centre or national KPD registries. This review focuses on the first 4 years of experience with the Australian multi-centre KPD programme that was established in October 2010. © 2014 Asian Pacific Society of Nephrology.

Liver procurement from a brain-dead kidney transplant recipient--a case report.

Romatowska, Edyta; Woderska, Aleksandra; Kusza, Krzysztof; Słupski, Maciej; Neumann, Małgorzata

2012-01-01

The shortage of organ donors has led to new strategies to increase the availability of allografts for transplantation, such as organ procurement from brain-dead organ transplant recipients. We present the case of a 26 year-old male brain-dead liver donor who had been a kidney transplant recipient six years previously. The liver donor described in this report, as the first in Poland, has paved a new, although as yet narrow, way in the field of organ donation. This is also the first case described in the medical literature of liver recovery from a brain-dead kidney transplant recipient on an immunosuppressive regimen with three immunosuppressive agents. Although transplant recipients represent an uncommon group of deceased organ donors, it is probable that situations when they may be considered as potential organ donors will occur more often. Therefore, although specific criteria for organ donors exist, each reported potential donor should be considered individually, and brain-dead solid organ recipients should not be excluded a priori as organ donors; both their native and allografted organs may be recovered and successfully transplanted. In this study, we also review the current state of knowledge on the reuse of organs.

BACKGROUND T lymphocytes are an essential component of allograft rejection and tolerance. The aim of the present study was to analyze and compare the characteristics of T cell subsets in patients who underwent deceased donor liver transplantation (DDLT) versus living donor liver transplantation (LDLT). MATERIAL AND METHODS Between April 2013 and June 2014, 64 patients underwent adult liver transplantation. The distribution of peripheral blood T lymphocyte subsets before transplantation and at 4, 8, 12, and 24 weeks post-transplantation were monitored serially. RESULTS In the serial peripheral blood samples, the absolute CD3+ T cell counts in the LDLT group were higher than those in the DDLT group (p=0.037). The CD4+, CD8+, CD4/CD8, Vδ1, Vδ2, and γδ T cell counts did not change significantly over time in either group. The Vδ1/Vδ2 ratio was higher in patients with cytomegalovirus (CMV) infection than in patients without CMV infection (0.12 versus 0.26; p=0.033). The median absolute CD3+ and CD8+ T cell counts in patients with biopsy-proven acute rejection (BPAR) were 884 (range, 305-1,320) and 316 (range, 271-1,077), respectively, whereas they were 320 (range, 8-1,167) and 257 (range, 58-1,472) in patients without BPAR. The absolute CD3+ and CD8 T cell counts were higher in patients with BPAR than in patients without BPAR (p=0.007 and p=0.039, respectively). CONCLUSIONS With the exception of CD3+ T cells, T cell populations did not differ significantly between patients who received DDLT versus LDLT. In liver transplantation patients, CMV infection and BPAR were closely associated with T cell population changes.

Type 2 diabetes mellitus (DM) is the commonest cause of end-stage renal disease (ESRD) worldwide. Renal transplantation (RTx) is the best therapeutic modality for such patients. First-degree relatives of patients with type 2 DM have high risk of diabetes/pre-diabetes. Parents are often too old to be suitable donors, and siblings/children/spouse are either not suitable/acceptable or do not come forward for organ donation. This leaves deceased donation (DD) as only suitable donors. Data scarcity on DDRTx outcome in diabetic nephropathy (DN) prompted us to review our experience. This retrospective single-center 10-year study was undertaken to evaluate patient/graft survival, graft function, rejection episodes, and mortality in these patients. Between January 2001 and March 2011, thirty-five DN-ESRD patients underwent DDRTx in our center following cardiac fitness assessment of recipients. All patients received single-dose rabbit-anti-thymocyte globulin for induction and steroids, calcineurin inhibitor, and mycophenolate mofetil/azathioprine for maintenance immunosuppression. Mean recipient age was 49.66 ± 6.76 years, and 25 were men. Mean donor age was 50 ± 16.45 years, 23 were men. Over a mean follow-up of 2.28 ± 2.59 years, patient and graft survival rates were 68.5% and 88.5%, respectively, with mean SCr of 1.9 ± 0.62 mg/dl. Delayed graft function was observed in 34.3% patients, and 25.7% had biopsy-proven acute rejection; 31.5% patients died, mainly because of infections (22.8%), coronary artery disease (2.86%), and cerebrovascular events (5.7%). DDRTx in patients with DN has acceptable graft function and patient/graft survival over 10-year follow-up in our center and, therefore, we believe it should be encouraged.

The impact of slow graft function on graft outcome is comparable to delayed graft function in deceased donor kidney transplantation.

Slow graft function (SGF) can influence overall prognosis in patients receiving deceased donor kidney transplantation (DKT). However, the impact of SGF on renal function remains uncertain. We investigated retrospectively renal function in cases with SGF compared with early graft function (EGF) and delayed graft function (DGF). Renal function after transplantation was analyzed in 199 patients who underwent DKT. Patients were classified into 130 (65.3 %) cases with EGF, 27 (13.6 %) cases with SGF, 6 (3.0 %) cases with DGF and one dialysis (DGF1), and 36 (18.1 %) cases with DGF and two or more dialyses (DGF2). The 1-year estimated glomerular filtration rate (eGFR) in the SGF group was lower than that in the EGF group (P = 0.027), but the rate of eGFR decline did not differ between the groups. The risk factors for renal function were evaluated using the area under the eGFR curve over 3 years (AUCeGFR). Donor age was negatively, and recipient age and the number of HLA matches were positively correlated with the AUCeGFR (all P < 0.05). A multivariate analysis revealed that the AUCeGFR was lower in cases of younger recipient age, older donor age, and acute rejection (all P < 0.05). The AUCeGFR was significantly lower in the SGF and DGF2 groups compared with the EGF group (P = 0.031 and 0.006, respectively). SGF may be an independent risk factor for poor renal function after DKT. Moreover, it was comparable to DGF. Efforts should be dedicated to minimizing the development of SGF and DGF.

Kidney transplantation is the better option for end-stage renal disease (ESRD), but for patients with human leukocyte antigen (HLA) sensitization, the wait times are significantly longer than for patients without antibodies. Many desensitization protocols have been described involving strong immunosuppression, the use of apheresis, and B-cell-modulating therapies. We have designed a desensitization protocol from day 0 for deceased donor kidney transplantation. Our aim was to present our initial experience with five kidney transplant patients. All patients had a negative complement-dependent cytotoxicity cross-match. The desensitization protocol included five to seven doses of thymoglobulin (1.25 mg/kg) and three sessions of plasmapheresis (PP) within the first week after transplantation, with intravenous immunoglobulin (500 mg/kg) after each PP session and one dose of rituximab on day 8. The presence of donor-specific antibodies (DSA) was analyzed by use of Luminex technology; levels between 1000 and 3000 mean fluorescence intensity were considered for desensitization. The median age was 44 years and median renal replacement therapy time was 9 years. All recipients presented 1 to 3 DSA specificities. There were no severe side effects related to PP, infusion of intravenous immunoglobulin, or rituximab. The median follow-up period was 19.3 months. Median serum creatinine level at last follow-up was 1.7 mg/dL. A kidney biopsy was performed in all patients. Graft and patient survival was 100%. Until now, few data are available concerning whether HLA-incompatible kidney transplantation after desensitization would benefit patients with ERSD. The desensitization strategy using the combination of PP, low doses of intravenous immunoglobulin, and rituximab at our center resulted in a satisfactory clinical outcome.

Donor-transmitted, donor-derived, and de novo cancer after liver transplant.

PubMed

Chapman, Jeremy R; Lynch, Stephen V

2014-03-01

Cancer is the third most common cause of death (after cardiovascular disease and infection) for patients who have a functioning kidney allograft. Kidney and liver transplant recipients have similar cancer risks because of immunosuppression but different risks because of differences in primary diseases that cause renal and hepatic failure and the inherent behavior of cancers in the liver. There are 4 types of cancer that may develop in liver allograft recipients: (1) recurrent cancer, (2) donor-transmitted cancer, (3) donor-derived cancer, and (4) de novo cancer. Identification of potential donor cancer transmission may occur at postmortem examination of a deceased donor or when a probable donor-transmitted cancer is identified in another recipient. Donor-transmitted cancer after liver transplant is rare in Australia, the United Kingdom, and the United States. Aging of the donor pool may increase the risk of subclinical cancer in donors. Liver transplant recipients have a greater risk of de novo cancer than the general population, and risk factors for de novo cancer in liver transplant recipients include primary sclerosing cholangitis, alcoholic liver disease, smoking, and increased age. Liver transplant recipients may benefit from cancer screening because they have a high risk, are clearly identifiable, and are under continuous medical supervision.

The growing disparity between organ supply and demand has become the greatest hurdle facing transplant professionals and life-saving transplants. Because the organ shortage has become the rate-limiting step to effective transplants, it is critical for the transplant community to identify viable mechanisms to expand the donor pool and use every available allograft. Although using kidneys from deceased donors whose demise was secondary to ethylene glycol (EG) toxicity requires great deliberation and precise timing as described by Barbas et al [5], using hepatic allografts in this setting involves far less risk. The following is a discussion of a 61-year-old male who was diagnosed with end-stage liver disease secondary to non-alcoholic steatohepatitis and ultimately underwent a life-saving transplant with a liver recovered from a donor with EG-induced brain death and allocated nationally due to trepidation by local and regional centers to use the liver from a donor after EG toxicity.

Due to a tremendous organ shortage, livers from donors with extended criteria are increasingly considered for transplantation. Pathologists are more and more requested to evaluate these livers histopathologically using frozen sections at high urgency for acceptability. This article reviews the current knowledge on pre-transplant histology in liver transplantation. Prerequisites and conditions for proper pre-transplant evaluation of donor liver tissue are discussed as well as frozen section evaluation and reporting. Data sources include the relevant medical literature, web sites specialized in organ transplantation, and the authors' experiences in liver transplant centers. Pre-transplant histopathological evaluation is a time-effective, accurate, and reliable tool to assess liver quality from candidate deceased donors. Pre-transplant biopsies are of value in the selection of donor livers for transplantation, especially in case of extended criteria donors, and should be performed more frequently in order to avoid unnecessary loss of organs suitable for transplantation and transplantation of inappropriate organs. Correlation of histopathological findings with clinical conditions is essential and requires excellent communication between pathologists, surgeons, and the other members of the transplant team.

Compared with evident cornea donors (ECDs), deceased potential cornea donors (DPCDs) have no obvious donor identifications to reference, which causes many eligible cornea tissues to be wasted. The demographic characteristics of DPCDs might be different from those of ECDs owing to the following different features: donation consent provided by relatives and willingness to donate before death. Thus, the aim of this study is to reveal the demographic characteristics of DPCDs by comparing DPCDs and ECDs.The demographic factors of 138 donors (both DPCDs and ECDs) were collected from the Beijing Tongren Hospital Eye Bank database and analyzed. To differentiate DPCDs from ECDs using the above-mentioned features, we interviewed the relatives of the donors by telephone. The relatives' attitudes toward cornea donation and their suggestions for our donation service were also acquired during the interview. Two logistic regressions were performed to reveal the demographic factors influencing the 2 features and indicate DPCDs.The donors had certain demographic characteristics (elderly, secondary, or tertiary education level, central district resident), and the most frequent cause of death for the donors was a malignant tumor (n = 56, 43.1%). All the relatives had positive attitudes toward cornea donations, and they hoped to increase publicity efforts to encourage more people to donate and establish more convenient and efficient access for cornea donation. In univariate regressions, age (P = .004, >50 years: odds ratio [OR] = 6.89, 95% confidence interval [CI]: 1.82-26.05), marital status (P = .043, divorced: OR = 9.00,95% CI: 1.33-60.80) significantly influenced relative consent, whereas age (P = .001, >50 years: OR = 15.00, 95% CI: 3.00-74.98), and family address (P = .001, central district: OR = 1) were significant factors influencing the willingness to donate before death. In multivariate regression, age (P = .021, >50 years: OR = 8.14, 95% CI: 1.37-48.41) was the only significant factor influencing relative consent. Similarly, age (P = .02, >50 years: OR = 7.55, 95% CI: 1.21-47.25) was the only factor influencing willingness to donate before death.In conclusion, specific demographic factors could indicate DPCDs and might reveal directions and methods for cornea donation coordination in the future.

To expand the donor liver pool, ways are sought to better define the limits of marginally transplantable organs. The Donor Risk Index (DRI) lists 7 donor characteristics, together with cold ischemia time and location of the donor, as risk factors for graft failure. We hypothesized that donor hepatic steatosis is an additional independent risk factor. We analyzed the Scientific Registry of Transplant Recipients for all adult liver transplants performed from October 1, 2003, through February 6, 2008, with grafts from deceased donors to identify donor characteristics and procurement logistics parameters predictive of decreased graft survival. A proportional hazard model of donor variables, including percent steatosis from higher-risk donors, was created with graft survival as the primary outcome. Of 21,777 transplants, 5051 donors had percent macrovesicular steatosis recorded on donor liver biopsy. Compared to the 16,726 donors with no recorded liver biopsy, the donors with biopsied livers had a higher DRI, were older and more obese, and a higher percentage died from anoxia or stroke than from head trauma. The donors whose livers were biopsied became our study group. Factors most strongly associated with graft failure at 1 year after transplantation with livers from this high-risk donor group were donor age, donor liver macrovesicular steatosis, cold ischemia time, and donation after cardiac death status. In conclusion, in a high-risk donor group, macrovesicular steatosis is an independent risk factor for graft survival, along with other factors of the DRI including donor age, donor race, donation after cardiac death status, and cold ischemia time.

Belatacept provides effective immunosuppression while avoiding the nephrotoxicities associated with calcineurin inhibitors (CNIs). However, existing belatacept-based regimens still have high rates of acute rejection. We hypothesized that therapy with belatacept, mycophenolic acid (MMA), steroids and induction therapy with rabbit anti-thymocyte globulin Fresenius (ATGF), rejection rate could be reduced. Prospective, single center, proof-of-concept study including males and females aged ≥18years, Epstein-Barr virus (EBV)-seropositive recipients of a first, HLA non-identical, live or deceased donor kidney allograft. Only patients with a calculated panel reactive antibody score of 0% were included. Three donors were positive for Chagas disease. Six of twelve patients had at least one infection and five were readmitted to the hospital for treatment. One patient had a Trypanosoma cruzi infection via the graft treated successfully. Median cold ischemia time for the transplant patients with a deceased donor was 21.5h. Mean serum creatinine levels at 1, 3 and 6months were 1.76±0.59, 1.55±0.60 and 1.49±0.60mg/dl, respectively. Two of twelve patients experienced clinical, biopsy-proven rejection, successfully treated with methylprednisolone. No patient developed post-transplant lymphoproliferative disorder (PTLD) or any other malignancy and no patient lost their graft or died during follow-up. The potential of this approach makes it worthy of further investigation. Copyright © 2014 Elsevier B.V. All rights reserved.

Deceased donor liver transplantation is nowadays a routine procedure for the treatment of terminal liver failure and often represents the only chance of a cure. Under given optimal conditions excellent long-term results can be obtained with 15-year survival rates of well above 60 %.In Germany the outcome after liver transplantation has deteriorated since the introduction of an allocation policy, which is based on the medical urgency. At present 25 % of liver graft recipients die within the first year after transplantation. In contrast 1-year survival in most other countries, e.g. in the USA or the United Kingdom is around 90 % and therefore significantly better. Reasons for the inferior results in Germany are on the one hand an increasing number of critically ill recipients and on the other hand an unfavorable situation for organ donation. In comparison with other countries the organ donation rate is low and moreover the risk profile of these donors is above average. This combination of organ shortage and organ allocation represents a big challenge for the future orientation of liver transplantation and creates the potential for conflict. These cannot be solved on a medical basis but require a social consensus.Because of the present inferior results and because of the high expenses of the present system we suggest a discussion on future allocation policies as well as on future centre structures in Germany. In addition to the medical urgency the maximum benefit should also be considered for organ allocation.

Living kidney donation offers superior outcomes over deceased organ donation, but incurs psychosocial and ethical challenges for recipients because of the risks imposed on their donor. We aimed to describe the beliefs, attitudes, and expectations of patients with chronic kidney disease toward receiving a living kidney donor transplant. We conducted a systematic review of qualitative studies of patients' attitudes toward living kidney donation using a comprehensive literature search of electronic databases to February 2013. The findings were analyzed using thematic synthesis. Thirty-nine studies (n ≥ 1791 participants) were included. We identified six themes: prioritizing own health (better graft survival, accepting risk, and desperate aversion to dialysis), guilt and responsibility (jeopardizing donor health, anticipating donor regret, and causing donor inconvenience), ambivalence and uncertainty (doubting transplant urgency, insufficient information, confronted by unfamiliarity, and prognostic uncertainty), seeking decisional validation (a familial obligation, alleviating family burden, reciprocal benefits for donors, respecting donor autonomy, external reassurance, and religious approval), needing social support (avoiding family conflict, unrelenting indebtedness, and emotional isolation), and cautious donor recruitment (self-advocacy, lacking self-confidence, avoiding donor coercion, emotional vulnerability, respecting cultural, and religious taboos). Enhanced education and psychosocial support may help clarify, validate, and address patients' concerns regarding donor outcomes, guilt, relationship tensions, and donor recruitment. This may encourage informed decision-making, increase access to living kidney donation, and improve psychosocial adjustment for transplant recipients.

Worldwide shortage of standard brain dead donors (DBD) has revived the use of kidneys donated after circulatory death (DCD). We reviewed the Belgian DCD kidney transplant (KT) experience since its reintroduction in 2000. Risk factors for delayed graft function (DGF) were identified using multivariate analysis. Five-year patient/graft survival was assessed using Kaplan-Meier curves. The evolution of the kidney donor type and the impact of DCDs on the total KT activity in Belgium were compared with the Netherlands. Between 2000 and 2009, 287 DCD KT were performed. Primary nonfunction occurred in 1% and DGF in 31%. Five-year patient and death-censored graft survival were 93% and 95%, respectively. In multivariate analysis, cold storage (versus machine perfusion), cold ischemic time, and histidine-tryptophan-ketoglutarate solution were independent risk factors for the development of DGF. Despite an increased number of DCD donations and transplantations, the total number of deceased KT did not increase significantly. This could suggest a shift from DBDs to DCDs. To increase KT activity, Belgium should further expand controlled DCD programs while simultaneously improve the identification of all potential DBDs and avoid their referral for donation as DCDs before brain death occurs. Furthermore, living donation remains underused. © 2012 The Authors. Transplant International © 2012 European Society for Organ Transplantation.

Policy options for increasing the supply of transplantable kidneys in Singapore

Chong, Jia Loon

2016-01-01

Kidney transplantation is the preferred treatment for eligible end-stage renal disease patients. However, the supply of donated kidneys has been consistently insufficient to meet the transplantation requirements of the population. In this paper, I discuss the feasibility of several policy options that engage potential donors or key individuals in a Singapore context, including financial and non-financial incentives for deceased/living organ donors and their families, improving actualisation rates of both donation after brain death, donation after cardiac death through quality improvement programmes and remuneration schemes, and a media platform for directed organ donation. I conclude by highlighting the most feasible policies to be considered. PMID:27779281

Recent Progress in Cell Therapy in Solid Organ Transplantation

There has been ample of preclinical and animal studies showing efficacy and safety of using various cells, such as stem cells or T regulatory cells, after transplantation for tissue repair, immunosuppression or tolerance induction. However, there has been a significant progress recently using cell therapy in solid organ transplantation in small clinical trials. Recent results have been promising and using cell therapy in solid organ transplantation seems feasible and safe. However, there are more hurdles to overcome such as dose and timing of the infusions. Current studies mainly focused on live donor kidney transplantation. Expansion of current regimes to other organs and deceased donor transplantation would be crucial. PMID:28924460

Maximizing Nephron Mass in Horseshoe Kidney Transplantation Using Inferior Epigastric Artery: Case Report.

Due to the progressive shortage of donors, kidneys with congenital anomalies are considered for transplantation. We report a successful transplantation of a split horseshoe kidney from a deceased donor by using the inferior epigastric artery with an end-to-end anastomosis, supplying the isthmus. Thus, we preserved as much as possible the functional parenchyma for a good long-term outcome. The learning point is that the use of the right inferior epigastric artery seems to be a good solution to perfuse the lower artery in order to avoid its ligation, thus reducing the nephron mass of the graft. © 2018 S.

We sought to determine whether ventilation of lungs after death in non-heart-beating donors with carbon monoxide during warm ischemia and ex vivo lung perfusion and after transplant would reduce ischemia-reperfusion injury and improve lung function. One hour after death, Sprague-Dawley rats were ventilated for another hour with 60% oxygen (control group) or 500 ppm carbon monoxide in 60% oxygen (CO-vent group; n=6/group). Then, lungs were flushed with 20 mL cold Perfadex, stored cold for 1 hour, then warmed to 37 °C in an ex vivo lung perfusion circuit perfused with Steen solution. At 37 °C, lungs were ventilated for 15 minutes with alveolar gas with or without 500 ppm carbon monoxide, then perfusion-cooled to 20 °C, flushed with cold Perfadex and stored cold for 2 hours. The left lung was transplanted using a modified cuff technique. Recipients were ventilated with 60% oxygen with or without carbon monoxide. One hour after transplant, we measured blood gases from the left pulmonary vein and aorta, and wet-to-dry ratio of both lungs. The RNA and protein extracted from graft lungs underwent real-time polymerase chain reaction and Western blotting, and measurement of cyclic guanosine monophosphate by enzyme-linked immunosorbent assay. Carbon monoxide ventilation begun 1 hour after death reduced wet/dry ratio after ex vivo lung perfusion. After transplantation, the carbon monoxide-ventilation group had better oxygenation; higher levels of tissue cyclic guanosine monophosphate, heme oxidase-1 expression, and p38 phosphorylation; reduced c-Jun N-terminal kinase phosphorylation; and reduced expression of interleukin-6 and interleukin-1β messenger RNA. Administration of carbon monoxide to the deceased donor and non-heart-beating donor lungs reduces ischemia-reperfusion injury in rat lungs transplanted from non-heart-beating donors. Therapy to the deceased donor via the airway may improve post-transplant lung function. Copyright © 2013 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

We performed a cost-effectiveness analysis exploring the cost and benefits of LDLT using outcomes data from the Adult to Adult Living Donor Liver Transplantation Cohort Study (A2ALL). A multistage Markov decision analysis model was developed with treatment strategies including medical management only (strategy 1), waiting list with possible deceased donor liver transplant (strategy 2), and waiting list with possible LDLT or DDLT (strategy 3) over ten years. Decompensated cirrhosis with medical management offered 2.0 quality adjusted life years (QALY) survival while costing an average of $65,068, waiting list with possible DDLT offered 4.4 QALY survival and a mean cost $151,613, and waiting list with possible DDLT or LDLT offered 4.9 QALY survival and a mean cost $208,149. Strategy 2 had an incremental cost effectiveness ratio (ICER) of $35,976 over strategy 1 while strategy 3 produced an ICER of $106,788 over strategy 2. On average, strategy 3 cost $47,693 more per QALY than strategy 1. Both DDLT and LDLT are cost-effective compared to medical management of cirrhosis over our ten year study period. The addition of LDLT to a standard waiting list DDLT program is effective at improving recipient survival and preventing waiting list deaths but at a greater cost. PMID:19177435

We conducted a randomized and unblinded 2 × 2 sequential-factorial trial, composed of an induction arm (part 1) comparing single-dose (SD) versus divided-dose rabbit antithymocyte globulin (rATG), and a maintenance arm (part 2) comparing tacrolimus minimization versus withdrawal. We report the long-term safety and efficacy of SD-rATG induction in the context of early steroid withdrawal and tacrolimus minimization or withdrawal. Patients (n=180) received 6 mg/kg rATG, SD or four alternate-day doses (1.5 mg/kg/dose), with early steroid withdrawal and tacrolimus or sirolimus maintenance. After 6 months targeted maintenance levels were tacrolimus, 2 to 4 ng/mL and sirolimus, 4 to 6 ng/mL or, if calcineurin inhibitor-withdrawn, sirolimus 8 to 12 ng/mL with mycophenolate mofetil 2 g two times per day. Primary endpoints were renal function (abbreviated modification of diet in renal disease) and chronic graft histopathology (Banff). Secondary endpoints included patient survival, graft survival, biopsy-proven rejection, and infectious or noninfectious complications. Follow-up averaged longer than 4 years. Tacrolimus or sirolimus and mycophenolate mofetil exposure was identical between groups. The SD-rATG associated with improved renal function (2-36 months; P<0.001) in deceased donor recipients. The SD-rATG associated with quicker lymphocyte, CD4 T cell, and CD4-CD8 recovery and fewer infections. Cox multivariate hazard modeling showed divided-dose-rATG (P=0.019), deceased donor (P=0.003), serious infection (P=0.0.018), and lower lymphocyte count (P=0.001) associated with increased mortality. Patients with all four covariates showed a 27-fold increased likelihood of death (P=0.00002). Chronic graft histopathology, rejection rates, and death-censored graft survival were not significantly different between groups. The SD-rATG induction improves the 3-year renal function in recipients of deceased donor kidneys. This benefit, along with possibly improved patient survival and fewer infections suggest that how rATG is administered may impact its efficacy and safety.

Financial aspects of organ procurement from deceased donors in the USA-Relevance to xenotransplantation.

PubMed

Saari, Ryan J; Cooper, David K C

2017-07-01

When clinical xenotransplantation is introduced, the costs associated with acquisition of a genetically engineered pig organ are as yet unknown. How will these costs compare with those currently associated with the acquisition of deceased human organs? An understanding of the financial aspects of deceased organ and tissue procurement in the USA is therefore worthwhile. We have therefore attempted to review certain economic aspects of non-profit and for-profit organizations that provide cadaveric organs and/or tissues for purposes of transplantation into patients with end-stage organ failure, cellular deficiencies, or in need of reconstructive procedures. We briefly consider the laws, organizations, and business practices that govern the acquisition, processing, and/or distribution of cadaveric organs and tissues, and the economic implications of industry practices. In particular, we explore and highlight what we perceive as a lack of transparency and oversight with regard to financial practices, and we question whether donor families would be entirely happy with the business environment that has developed from their altruistic donations. Until xenotransplantation becomes established clinically, which will negate the need for any system of organ procurement and allocation, we suggest that those involved in organ and cell transplantation, as well as those who participate in reconstructive surgery, should take responsibility to ensure that the financial practices associated with procurement are transparent, and overseen/regulated by a responsible authority. We suggest the major transplant societies should take a lead in this respect. The ability to acquire a genetically engineered pig organ whenever required through a simple commercial transaction (as in the acquisition of a life-saving drug) will be greatly to the patient's benefit. © 2017 John Wiley & Sons A/S.

The Mexican Institute of Transplantation (IMT) was created in 1999 in response to the need to meet the demand for transplants in the south of the country for patients with limited resources. Thanks to the synergy with private assistance foundations this task has been accomplished. To describe the IMT experience in kidney transplants. From November 1999 to May 23,2011, 754 kidney transplants were performed in the IMT, of which 733 were from living donors and only 21 from deceased donors. In our experience, the 10-year patient and graft survival were 84.4 and 72.4%, respectively. The average follow-up of patients was 44 months, it was during the first year after transplantation when most of patients were lost. More than 50% of patients have been supported by private assistance foundations. The IMT has participated in research protocols for phase II and phase III, for the development of new immunosuppressants. The synergy between our private medical institution and private assistance foundations has permitted to transplant low income patients, a similar association can be carried out in governmental health institutions that have overcharge in their transplant services.

The effect of donor body mass index (BMI) and donor type on kidney transplant outcomes has not been well studied. Scientific Registry of Transplant Recipients data on recipients of deceased-donor kidneys between 1997 and 2010 were reviewed. Donors were categorized by DCD status (DCD, 6932; non-DCD, 90,158) and BMI groups at 5 kg/m(2) increments: 18.5-24.9, 25-29.9, 30-34.9, 35-39.9, 40-44.9, and ≥ 45 kg/m(2) . The primary outcome, death-censored graft survival (DCGS), was adjusted for donor, recipient, and transplant characteristics. Among recipients of non-DCD kidneys, donor BMI was not associated with DCGS. Among DCD recipients, donor BMI was not associated with DCGS for donor BMI categories < 45 kg/m(2) ; however, donor BMI ≥ 45 kg/m(2) was independently associated with DCGS compared to BMI of 20-24.9 kg/m(2) (adjusted hazard ratio, 1.84; 95% CI, 1.23, 2.74). The adjusted odds of delayed graft function (DGF) was greater for each level of BMI above reference for both DCD and non-DCD groups. There was no association of donor BMI with one-yr acute rejection for either type of donor. Although BMI is associated with DGF, long-term graft survival is not affected except in the combination of DCD with extreme donor BMI ≥ 45. © 2012 John Wiley & Sons A/S.

Classical MSUD is often fatal without appropriate medical interventions because of metabolic crisis. There are numerous reports suggesting the therapeutic potential of deceased donor liver transplantation for MSUD. However, the usefulness of LDLT for MSUD is unknown. We report a case of classical MSUD, which was successfully managed by LDLT from the patient's father at 1 year of age. Abnormal brain findings, which were cured with effective treatment, gradually disappeared after LDLT. The patient then developed normally. Findings from this case suggest the importance of LDLT for maintaining low leucine levels and subsequent normal neurological development. Although LDLT involves a modest surgical insult, LDLT with a related donor achieves acceptable leucine levels for life. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Older liver grafts have been considered in the past decade due to organ shortage. The aim was to compare outcomes after liver transplantation with either younger or older donors. Patients transplanted in our center between 2004 and 2014 with younger donors (younger than 60 years; n = 253) were compared with older donors (older than 75 years; n = 157). Multiorgan transplantations, split grafts, or non-heart-beating donors were not included. Donors in the older group were mostly women deceased from stroke, and only 3 patients had experienced cardiac arrest. Liver tests were significantly better in the older group than in the younger group. There was no difference regarding cold ischemia time, model for end-stage liver disease score, and steatosis. There was no significant difference regarding primary nonfunction and dysfunction, hepatic artery and biliary complications, and retransplantation rates. Graft survival was not different (65% and 64% in the older and younger groups, P = 0.692). Within the older group, hepatitis C infection, retransplantation, and emergency transplantation were associated with poor graft survival. Provided normal liver tests and the absence of cardiac arrest in donors, older liver grafts (>75 years) may be safely attributed to non-hepatitis C-infected recipients in the setting of a first and nonurgent transplantation.

The Report of the Task Force recommended that "educational efforts aimed at increasing organ donation among minority populations be developed and implemented, so that the donor population will more closely reflect the ethnicity of potential transplant recipients, in order to gain the advantage of improved donor and recipient immunologic matching (DHHS,1986). Donor rates for minorities has increased as follows: 16% in 1988 to 23% in 1995 among cadaveric donors and 24% in 1988 to 28% in 1995 among living donors. The improvement in donor rates among minorities may positively affect the transplantation success rate experienced by organ recipients of the same race. Strategies must be implemented that will increase the effectiveness and frequency of communication between minority patients and the medical community. An increase in the effectiveness of communication between potential minority donor families and the health care community will contribute to the process of Consciousness Raising as discussed by Prochasksa. The result of increased awareness of the organ donation and transplantation process may have a favorable impact on organ donation. The media has, through public service announcements, paid advertising and entertainment programming, attempted to promote discussion of organ donation in the community and within families. Johnson et al. discussed Mexican-American and Anglo-American Attitudes Toward Organ Donation. The primary impediment contributing to the disparity of consent rates between Mexican-American and Anglo-American population occurs with regard to the donation of organs of relatives. Johnson stated that this impediment to organ donation can be effectively addressed by promoting family discussion. Communication within families will inform surviving next of kin of the desire of the deceased to be an organ donor and hence improve the likelihood of the donor family consenting to organ donation (Johnson et al., 1988). The promotion of communication within families must continue to be a goal of the transplant community regardless of race/ethnicity. Despite the efforts of the government, the transplant community, the media and the corporate sector to address the critical shortage of donors in the United States, the reality is that no community has the supply of donor organs suitable to meet the need.

Purpose of review This review updates the current status of basic, preclinical, and clinical research on donor hematopoietic stem cell infusion for allograft tolerance induction. Recent findings Recent basic studies in mice provide evidence of significant involvement of both central deletional and peripheral regulatory mechanisms in induction and maintenance of allograft tolerance effected through a mixed chimerism approach with donor hematopoietic stem cell infusion. The presence of heterologous memory T cells in primates hampers the induction of persistent chimerism. Durable mixed chimerism, however, now has been recently induced in inbred major histocompatibility complex-mismatched swine, resulting in tolerance of vascularized composite tissue allografts. In clinical transplantation, allograft tolerance has been achieved in human leukocyte antigen-mismatched kidney transplantation after the induction of transient mixed chimerism or persistent full donor chimerism. Summary Tolerance induction in clinical kidney transplantation has been achieved by donor hematopoietic stem cell infusion. Improving the consistency and safety of tolerance induction and extending successful protocols to other organs, as well as to organs from deceased donors, are critical next steps to bringing tolerance to a wider range of clinical applications.

Obtaining corneal tissue for keratoplasty.

Navarro Martínez-Cantullera, A; Calatayud Pinuaga, M

Cornea transplant is the most common tissue transplant in the world. In Spain, tissue donation activities depend upon transplant coordinator activities and the well-known Spanish model for organ and tissue donation. Tissue donor detection system and tissue donor evaluation is performed mainly by transplant coordinators using the Spanish model on donation. The evaluation of a potential tissue donor from detection until recovery is based on an exhaustive review of the medical and social history, physical examination, family interview to determine will of the deceased, and a laboratory screening test. Corneal acceptance criteria for transplantation have a wider spectrum than other tissues, as donors with active malignancies and infections are accepted for kearatoplasty in most tissue banks. Corneal evaluation during the whole process is performed to ensure the safety of the donor and the recipient, as well as an effective transplant. Last step before processing, corneal recovery, must be performed under standard operating procedures and in a correct environment. Copyright © 2016 Sociedad Española de Oftalmología.

Legal and ethical issues of uterus transplantation.

PubMed

Dickens, Bernard M

2016-04-01

The clinically detailed report of a successful uterus transplantation and live birth in Sweden, in which a family friend donated her uterus, provides a basis for expanded practice. Family members and friends can serve as living donors without offending legal or ethical prohibitions of paid organ donation, even though family members and friends often engage in reciprocal gift exchanges. Donations from living unrelated sources are more problematic, and there is a need to monitor donors' genuine altruism and motivation. Donation by deceased women-i.e. cadaveric donation-raises issues of uterus suitability for transplantation, and how death is diagnosed. Organs' suitability for donation is often achieved by ventilation to maintain cardiac function for blood circulation, but laws and cultures could deem that a heartbeat indicates donors' live status. Issues could arise concerning ownership and control of organs between recovery from donors and implantation into recipients, and on removal following childbirth, that require legal resolution.

Cardiac arrest (CA) in deceased organ donors can potentially be associated with ischaemic organ injury, resulting in allograft dysfunction after liver transplantation (LT). The aim of this study was to analyse the influence of cardiac arrest in liver donors. We evaluated 884 consecutive adult patients undergoing LT at our Institution from September 2003 to December 2011. Uni- and multivariable analyses was performed to identify predictive factors of outcome and survival for organs from donors with (CA donor) and without (no CA donor) a history of cardiac arrest. We identified 77 (8.7%) CA donors. Median resuscitation time was 16.5 (1-150) minutes. Allografts from CA donors had prolonged CIT (p = 0.016), were obtained from younger individuals (p < 0.001), and had higher terminal preprocurement AST and ALT (p < 0.001) than those of no CA donors. 3-month, 1-year and 5-year survival for recipients of CA donor grafts was 79%, 76% and 57% and 72.1%, 65.1% and 53% for no CA donor grafts (log rank p = 0.435). Peak AST after LT was significantly lower in CA donor organs than in no CA donor ones (886U/l vs 1321U/l; p = 0.031). Multivariable analysis identified CIT as a risk factor for both patient and graft survival in CA donors. This analysis represents the largest cohort of liver donors with a history of cardiac arrest. Reasonable selection of these donors constitutes a safe approach to the expansion of the donor pool. Rapid allocation and implantation with diminution of CIT may further improve the outcomes of livers from CA donors. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To minimize cold ischemia time, transplantations with kidneys from deceased donors are frequently performed during the night. However, sleep deprivation of those who perform the transplantation may have adverse effects on cognitive and psychomotor performance and may cause reduced cognitive flexibility. We hypothesize that renal transplantations performed during the night are associated with an increased incidence of pure technical graft failure. A retrospective analysis of data of the Dutch Organ Transplant Registry concerning all transplants from deceased donors between 2000 and 2013 was performed. Nighttime surgery was defined as the start of the procedure between 8 p.m. and 8 a.m. The primary outcome measure was technical graft failure, defined as graft loss within 10 days after surgery without signs of (hyper)acute rejection. Of 4.519 renal transplantations in adult recipients, 1.480 were performed during the night. The incidence of pure technical graft failure was 1.0 % for procedures started during the night versus 2.6 % for daytime surgery (p = .001). In a multivariable model, correcting for relevant donor, recipient and graft factors, daytime surgery was an independent predictor of pure technical graft failure (p < .001). Limitation of this study is mainly to its retrospective design, and the influence of some relevant variables, such as the experience level of the surgeon, could not be assessed. We conclude that nighttime surgery is associated with less pure technical graft failures. Further research is required to explore factors that may positively influence the performance of the surgical team during the night.

Social media platforms are increasingly used in surgery and have shown promise as effective tools to promote deceased donation and expand living donor transplantation. There is growing need to understand how social media-driven communication is perceived by providers in the field of transplantation. We surveyed 299 members of the American Society of Transplant Surgeons (ASTS) about their use of, attitudes toward, and perceptions of social media and analyzed relationships between responses and participant characteristics. Respondents used social media to communicate with: family and friends (76%), surgeons (59%), transplant professionals (57%), transplant recipients (21%), living donors (16%), and waitlisted candidates (15%). Most respondents (83%) reported using social media for at least one purpose. While most (61%) supported sharing information with transplant recipients via social media, 42% believed it should not be used to facilitate living donor-recipient matching. Younger age (p=0.02) and fewer years of experience in the field of transplantation (p=0.03) were associated with stronger belief that social media can be influential in living organ donation. Respondents at transplant centers with higher reported use of social media had more favorable views about sharing information with transplant recipients (p<0.01), increasing awareness about deceased organ donation (p<0.01), and advertising for transplant centers (p<0.01). Individual characteristics influence opinions about the role and clinical usefulness of social media. Transplant center involvement and support for social media may influence clinician perceptions and practices. Increasing use of social media among transplant professionals may provide an opportunity to deliver high quality information to patients.

Abstract Rising incomes, the spread of personal insurance, lifestyle factors adding to the burden of illness, ageing populations, globalization and skills transfer within the medical community have increased worldwide demand for organ transplantation. The Global Observatory on Donation and Transplantation, which was built in response to World Health Assembly resolution WHA57.18, has conducted ongoing documentation of global transplantation activities since 2007. In this paper, we use the Global Observatory’s data to describe the current distribution of – and trends in – transplantation activities and to evaluate the role of health systems factors and macroeconomics in the diffusion of transplantation technology. We then consider the implications of our results for health policies relating to organ donation and transplantation. Of the World Health Organization’s Member States, most now engage in organ transplantation and more than a third performed deceased donor transplantation in 2011. In general, the Member States that engage in organ transplantation have greater access to physician services and greater total health spending per capita than the Member States where organ transplantation is not performed. The provision of deceased donor transplantation was closely associated with high levels of gross national income per capita. There are several ways in which governments can support the ethical development of organ donation and transplantation programmes. Specifically, they can ensure that appropriate legislation, regulation and oversight are in place, and monitor donation and transplantation activities, practices and outcomes. Moreover, they can allocate resources towards the training of specialist physicians, surgeons and transplant coordinators, and implement a professional donor-procurement network. PMID:25378744

Prior Family Communication and Consent to Organ Donation: Using Intensive Care Physicians’ Perception to Model Decision Processes

2012-01-01

Generally, the Swiss hold favourable attitudes to organ donation, but only few carry a donor card. If no card is found on a potential donor, families have to be approached about donation. The aim of this paper is to model the role that some family communication factors play in the family decision to consent or not to organ donation by a brain dead relative. Information was gathered in face-to-face interviews, using a questionnaire and recording open answers and comments. Eight heads of intensive care units (ICU) of Swiss hospitals and one representative from Swisstransplant were interviewed. Questions asked respondents to estimate the prevalence and effect of communication factors in families facing a decision to consent to donation. Answers were averaged for modelling purposes. Modelling also relies on a previous representative population survey for cross-validation. The family of the deceased person is almost always approached about donation. Physicians perceive that prior thinking and favourable predisposition to donation are correlated and that the relatives’ predisposition is the most important factor for the consent to donation, up to the point that a negative predisposition may override an acknowledged wish of the deceased to donate. Donor cards may trigger family communication and ease the physicians’ approach to family about donation. Campaigns should encourage donate-willing people to talk to their families about it, make people think about organ donation and try to change unfavourable predispositions. Acknowledgement the authors wish to thank the interviewees whose collaboration has provided them an overview of today’s situation in Switzerland. PMID:25170455

Objective Endoscopic procedures are becoming common in middle ear surgery. Inflammation due to chronic ear disease can cause bony erosion of the carotid artery and Fallopian canals, making them more vulnerable during surgery. The objective of this study was to determine whether or not chronic ear disease increases dehiscence of the carotid artery and Fallopian canals. Design Comparative human temporal bone study. Setting Otopathology laboratory. Participants We selected 78 temporal bones from 55 deceased donors with chronic otitis media or cholesteatoma, and then compared those 2 groups with a control group of 27 temporal bones from 19 deceased donors with no middle ear disease. Main outcome measures We analyzed the middle ear, carotid artery canal, and Fallopian canal, looking for signs of dehiscence of its bony coverage, using light microscopy. Results We found an increased incidence in dehiscence of the carotid artery and Fallopian canals in temporal bones with chronic middle ear disease. The size of the carotid artery canal dehiscence was larger in the middle ear diseased groups, and its bony coverage, when present, was also thinner compared to the control group. Dehiscence of the carotid artery canal was more frequently located closer to the promontory. The incidence of Fallopian canal dehiscence was significantly higher in temporal bones from donors older than 18 years with chronic middle ear disease. Conclusion The increased incidence of the carotid artery and Fallopian canal dehiscence in temporal bones with chronic middle ear disease elevates the risk of adverse events during middle ear surgery.

Kidney transplantation is the optimal therapy for the majority of patients with end-stage renal disease. However, the cost and health outcomes of transplantation have not been assessed in a middle-income nation with a low volume of transplantation, such as Malaysia. This study used microcosting methods to determine the cost and health outcomes of living and deceased donor kidney transplantation in adult and pediatric recipients. The perspective used was from the Ministry of Health Malaysia. Cost-effectiveness measures were cost per life year (LY) and cost per quality-adjusted LYs. The time horizon was the lifetime of the transplant recipient from transplant to death. Records of 206 KT recipients (118 adults and 88 children) were obtained for microcosting. In adults, discounted cost per LY was US $8609(Malaysian Ringgit [RM]29 482) and US $13 209(RM45 234) for living-donor kidney transplant (LKT) and deceased donor kidney transplant (DKT), respectively, whereas in children, it was US $10 485(RM35 905) and US $14 985(RM51 317), respectively. Cost per quality-adjusted LY in adults was US $8826 (RM30 224) for LKT and US $13 592(RM46 546) for DKT. Total lifetime discounted costs of adult transplants were US $119 702 (RM409 921) for LKT, US $147 152 (RM503 922) for DKT. Total costs for pediatric transplants were US $154 841(RM530 252) and US $159 313(RM545 566) for the 2 categories respectively. Both LKT and DKT are economically favorable for Malaysian adult and pediatric patients with ESRD and result in improvement in quality of life.

The shortage of organs for transplantation has led to increased use of organs procured from donors after cardiac death (DCD). The effects of cardiac death on the liver remain poorly understood, however. Using livers obtained from DCD versus donors after brain death (DBD), we aimed to understand how ischemia/reperfusion (I/R) injury alters expression of pro-inflammatory markers ceramides and influences graft leukocyte infiltration. Hepatocyte inflammation, as assessed by ceramide expression, was evaluated in DCD (n = 13) and DBD (n = 10) livers. Allograft expression of inflammatory and cell death markers, and allograft leukocyte infiltration were evaluated from a contemporaneous independent cohort of DCD (n = 22) and DBD (n = 13) livers. When examining the differences between transplant stages in each group, C18, C20, C24 ceramides showed significant difference in DBD (p<0.05) and C22 ceramide (p<0.05) were more pronounced for DCD. C18 ceramide is correlated to bilirubin, INR, and creatinine after transplant in DCD. Prior to transplantation, DCD livers have reduced leukocyte infiltration compared to DBD allografts. Following reperfusion, the neutrophil infiltration and platelet deposition was less prevalent in DCD grafts while cell death and recipients levels of serum aspartate aminotransferase (AST) of DCD allografts had significantly increased. These data suggest that I/R injury generate necrosis in the absence of a strong inflammatory response in DCD livers with an appreciable effect on early graft function. The long-term consequences of increased inflammation in DBD and increased cell death in DCD allografts are unknown and warrant further investigation.

Greater compatibility of human leucocyte antigen (HLA) alleles between kidney donors and recipients may lead to improved graft outcomes. This study aimed to compare the incidence of acute rejection and graft failure in zero-HLA-mismatched recipients of living-related (LD) and deceased donor (DD) kidney transplants. Using data from the Australia and New Zealand Dialysis and Transplant Registry, we compared the risk of any acute rejection and biopsy-proven acute rejection (BPAR) and graft failure in recipients of zero-HLA-mismatched kidneys between LD and DD using logistic and Cox regression models. Of the 931 zero-HLA-mismatched recipients transplanted between 1990 and 2012, 19 (2.0%) received kidneys from monozygotic/dizygotic twins (twin), 500 (53.7%) from nontwin LD and 412 (44.3%) from DD. Twin kidney transplant recipients did not experience rejection. Compared to DD transplant recipients, the risk of any acute rejection (adjusted odds ratio 0.52, 95%CI 0.34-0.79, P = 0.002) and overall graft failure (adjusted hazard ratio 0.55, 95%CI 0.41-0.73, P < 0.001) was significantly lower in LD recipients independent of initial immunosuppression, but not for BPAR (adjusted odds ratio 0.52, 95%CI 0.16-1.64, P = 0.263). Zero-HLA-mismatched DD kidney transplant recipients have a significantly higher risk of any acute rejection episodes and graft loss compared to zero-HLA-mismatched LD kidney transplant recipients. A cautious and careful approach in reducing immunosuppression appears to be warranted in this group of transplant recipients. © 2015 Steunstichting ESOT.

This study updates assessment of post-transplant outcomes in IgAN patients in the modern era of immunosuppression. Using UNOS/OPTN data, patients ≥18 yr of age with first kidney transplant (1/1/1999 to 12/31/2008) were analyzed. Multivariable Cox regression models and propensity score-based matching techniques were used to estimate hazard ratios (HRs) for death-censored allograft survival (DCGS) and patient survival in IgAN compared to non-IgAN. Results of multivariable regression were stratified by donor type (living vs. deceased). A total of 107, 747 recipients were included (4589 with IgAN and 103 158 with non-IgAN). Adjusted HR for DCGS showed no significant difference between IgAN and non-IgAN. IgAN had higher patient survival compared to non-IgAN (HR 0.54, 95% CI 0.47-0.62, p < 0.0001 for deceased donors; HR 0.42, 95% CI 0.33-0.54, p < 0.0001 for living donors). Propensity score-matched analysis was similar, with no significant difference in DCGS between matched groups and higher patient survival in IgAN patients compared to non-IgAN group (HR 0.54, 95% CI 0.47, 0.63; p-value <0.0001). IgAN patients with first kidney transplant have superior patient survival and similar graft survival compared to non-IgAN recipients. Results can be used in prognostication and informed decision-making about kidney transplantation in patients with IgAN. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

We reviewed the history, volume, outcomes, uniqueness, and challenges of living donor liver transplantation (LDLT) in Latin America. We used the data from the Latin American and Caribbean Transplant Society, local transplant societies, and opinions from local transplant experts. There are more than 160 active liver transplant teams in Latin America, but only 30 centers have used LDLT in the past 2 years. In 2014, 226 LDLTs were done in the region (8.5% of liver transplant activities). Living donor liver transplantation is mainly restricted to pediatric patients. Adult-to-adult LDLT activities decreased after the implementation of the model for end-stage liver disease score and a concomitant increase on the rate of deceased donors per million population. Posttransplant outcome analysis is not mandatory, transparent or regulated in most countries. More experienced teams have outcomes comparable to international expert centers, but donor and recipient morbidity might be underreported. Latin America lags behind in terms of the number of adult LDLT and the rate of living donor utilization in comparison with other continents with similar donation rates. Local alliances and collaborations with major transplant centers in the developed world will contribute to the development of LDLT in Latin America.

Ethical issues in organ transplantation.

PubMed

Abouna, George M

2003-01-01

Clinical organ transplantation has been recognized as one of the most gripping medical advances of the century as it provides a way of giving the gift of life to patients with terminal failure of vital organs, which requires the participation of other fellow human beings and of society by donating organs from deceased or living individuals. The increasing incidence of vital organ failure and the inadequate supply of organs, especially from cadavers, has created a wide gap between organ supply and organ demand, which has resulted in very long waiting times to receive an organ as well as an increasing number of deaths while waiting. These events have raised many ethical, moral and societal issues regarding supply, the methods of organ allocation, the use of living donors as volunteers including minors. It has also led to the practice of organ sale by entrepreneurs for financial gains in some parts the world through exploitation of the poor, for the benefit of the wealthy. The current advances in immunology and tissue engineering and the use of animal organs, xenotransplantation, while offering very promising solutions to many of these problems, also raise additional ethical and medical issues which must be considered by the medical profession as well as society. This review deals with the ethical and moral issues generated by the current advances in organ transplantation, the problem of organ supply versus organ demand and the appropriate allocation of available organs. It deals with the risks and benefits of organ donation from living donors, the appropriate and acceptable methods to increase organ donation from the deceased through the adoption of the principle of 'presumed consent', the right methods of providing acceptable appreciation and compensation for the family of the deceased as well as volunteer and altruistic donors, and the duties and responsibilities of the medical profession and society to help fellow humans. The review also deals with the appropriate and ethically acceptable ways of utilizing the recent advances of stem cell transplantation from adult versus fetal donors, tissue engineering and the use of organs from animals or xenotransplantation. Data provided in support of the concept that clinical organ and tissue transplantation can be more beneficial and life saving if everyone involved in the process, including physicians and medical institutions, respect and consider the best interests of the patients, as well as honor the ethical, moral and religious values of society and are not tempted to seek personal fame or financial rewards.

Kidney transplantation is the preferred treatment for eligible end-stage renal disease patients. However, the supply of donated kidneys has been consistently insufficient to meet the transplantation requirements of the population. In this paper, I discuss the feasibility of several policy options that engage potential donors or key individuals in a Singapore context, including financial and non-financial incentives for deceased/living organ donors and their families, improving actualisation rates of both donation after brain death, donation after cardiac death through quality improvement programmes and remuneration schemes, and a media platform for directed organ donation. I conclude by highlighting the most feasible policies to be considered. Copyright: © Singapore Medical Association.

To investigate blood cultures of deceased donors and report the confirmed transmission of bacterial infection from donors to liver recipients. We retrospectively studied the results of blood cultures among our donation after cardiac death (DCD) donors and calculated the donor-derived bacterial infection rates among liver recipients. Study participants underwent liver transplantation between January 1, 2010 and February 1, 2017. The study involved a total of 67 recipients of liver grafts from 67 DCD donors. We extracted the data of donors' and patients' characteristics, culture results and clinical outcomes, especially the post-transplant complications in liver recipients, from electronic medical records. We analyzed the characteristics of the donors and the corresponding liver recipients with emphasis put on donor-derived infections. Head trauma was the most common origin of death among our 67 DCD donors (46.3%). Blood taken prior to the procurement operation was cultured for 53 of the donors, with 17 episodes of bloodstream infections developing from 13 donors. The predominant organism isolated from the blood of donors was Gram-positive bacteria (70.6%). Only three (4.5%) of 67 liver recipients developed confirmed donor-derived bacterial infections, with two isolates of multidrug-resistant Klebsiella pneumoniae and one isolate of multidrug-resistant Enterobacter aerogenes. The liver recipients with donor-derived infections showed relation to higher crude mortality and graft loss rates (33.3% each) within 3 mo post transplantation, as compared to those without donor-derived infections (9.4% and 4.7%, respectively). All three liver recipients received appropriate antimicrobial therapy. Liver recipients have high occurrence of donor-derived infections. The liver recipients with donor-derived multidrug-resistant Enterobacteriaceae infections can have good outcome if appropriate antimicrobial therapy is given.

Elderly donor grafts for liver transplantation (LT) are recognized to be marginal grafts. The present study investigated the impact of using elderly donors for LT. Between June 1990 and August 2012, 1631 patients received LT at Kyoto University Hospital. Out of 1631 patients, 1597 patients received living donor liver transplantation (LDLT), whereas the other 34 patients underwent deceased donor liver transplantation (DDLT). Seventy-five grafts that were used came from individuals who were ≥60 years old. We retrospectively analyzed the recipients' survival rates according to donor age. The overall survival rates of the recipients of all LDLT (P < 0.001), adult-to-adult LDLT (P = 0.007), all DDLT (P = 0.026), and adult-to-adult DDLT (P = 0.011) were significantly lower for the elderly donor group versus the younger group and especially for those who were hepatitis C-positive. A multivariate analysis revealed that donor age, ABO incompatibility, and preoperative intensive care unit stay were independent risk factors for poor patient survival in adult-to-adult LDLT. However, no significant differences existed between the 2 groups among those who received adult-to-adult LDLT in and after April 2006. No significant association was found between donor age and incidence of acute cellular rejection. In conclusion, donor age was closely related to the survival rate for LDLT and DDLT, although the impact of donor age was not shown in the recent cases. © 2015 American Association for the Study of Liver Diseases.

Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others. To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns. Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others. One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern. Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

The need to expand the organ donor pool remains a formidable challenge in kidney transplantation (KT). The use of expanded criteria donors (ECDs) represents one approach, but kidney discard rates are high because of concerns regarding overall quality. Dual KT (DKT) may reduce organ discard and optimize the use of kidneys from marginal donors. We conducted a single-center retrospective review of outcomes in adult recipients of DKTs from adult marginal deceased donors (DD) defined by limited renal functional capacity. If the calculated creatinine clearance in an adult DD was <65 mL/min, then the kidneys were transplanted as a DKT. Over 11.5 yr, 72 DKTS were performed including 45 from ECDs, 17 from donation after cardiac death (DCD) donors, and 10 from standard criteria donors (SCD). Mean adult DD and recipient ages were both 60 yr, including 29 DDs and 26 recipients ≥65 yr of age. Mean pre-DKT waiting and dialysis vintage times were 12 months and 25 months, respectively. Actual patient and graft survival rates were 84.7% and 70.8%, respectively, with a mean follow-up of 58 months. One yr and death-censored graft survival rates were 90% and 80%, respectively. Outcomes did not differ by DD category, recipient age, or presence of delayed graft function (DGF). Eleven patients died at a mean of 32 months post-DKT (eight with functioning grafts) and 13 other patients experienced graft losses at a mean of 33 months. The incidence of DGF was 25%; there were two cases (2.8%) of primary non-function. Mean length of initial hospital stay was 7.2 d. Mean serum creatinine and glomerular filtration rate levels at 12 and 24 months were 1.5 and 53 and 1.5 mg/dL and 51 mL/min/1.73 m(2) , respectively. DKT graft survival and function were superior to concurrent single ECD and similar to concurrent SCD KTs. Two patients underwent successful kidney retransplantation, so the dialysis-free rate in surviving patients was 87%. The proportion of total renal function transplanted from adult DD to DKT recipients was 77% compared to 56% for patients receiving single KTs. Dual kidney transplantation using kidneys from adult marginal DDs that otherwise might be discarded offer a viable option to counteract the growing shortage of acceptable single kidneys. Excellent medium-term outcomes can be achieved and waiting times can be reduced in a predominantly older recipient population. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

AIM To investigate blood cultures of deceased donors and report the confirmed transmission of bacterial infection from donors to liver recipients. METHODS We retrospectively studied the results of blood cultures among our donation after cardiac death (DCD) donors and calculated the donor-derived bacterial infection rates among liver recipients. Study participants underwent liver transplantation between January 1, 2010 and February 1, 2017. The study involved a total of 67 recipients of liver grafts from 67 DCD donors. We extracted the data of donors’ and patients’ characteristics, culture results and clinical outcomes, especially the post-transplant complications in liver recipients, from electronic medical records. We analyzed the characteristics of the donors and the corresponding liver recipients with emphasis put on donor-derived infections. RESULTS Head trauma was the most common origin of death among our 67 DCD donors (46.3%). Blood taken prior to the procurement operation was cultured for 53 of the donors, with 17 episodes of bloodstream infections developing from 13 donors. The predominant organism isolated from the blood of donors was Gram-positive bacteria (70.6%). Only three (4.5%) of 67 liver recipients developed confirmed donor-derived bacterial infections, with two isolates of multidrug-resistant Klebsiella pneumoniae and one isolate of multidrug-resistant Enterobacter aerogenes. The liver recipients with donor-derived infections showed relation to higher crude mortality and graft loss rates (33.3% each) within 3 mo post transplantation, as compared to those without donor-derived infections (9.4% and 4.7%, respectively). All three liver recipients received appropriate antimicrobial therapy. CONCLUSION Liver recipients have high occurrence of donor-derived infections. The liver recipients with donor-derived multidrug-resistant Enterobacteriaceae infections can have good outcome if appropriate antimicrobial therapy is given. PMID:28883707

Transplantation of the blood group A2B in a recipient was successfully performed in the setting of receiving a deceased donor kidney from an "incompatible" A1B donor. The donor and recipient were both typed for ABO blood group, including ABO genotyping. The donor and recipient were tested for ABO, non-ABO, and human leukocyte antigen (HLA) antibodies. The donor and recipient were typed for HLA antigens, including T- and B-flow cytometry crossmatch tests. The recipient's RBCs were negative with A1 lectin, and immunoglobulin G anti-A1 was demonstrated in the recipient's plasma. The donor-recipient pair was a four-antigen HLA mismatch, but final T- and B-flow cytometry crossmatch tests were compatible. The transplant procedure was uneventful; the patient experienced immediate graft function with no episodes of rejection or readmissions more than 2 years later. It may be safe to transplant across the A1/A2 blood group AB mismatch barrier in the setting of low titer anti-A1 isoagglutinins without the need for pretransplant desensitization even if the antibody produced reacts with anti-human globulin. © American Society for Clinical Pathology, 2016.

An altar in honor of the anatomical gift.

On All Saints Day 2009 a monument for body donors was unveiled by the Department of Anatomy, at the Radboud University Nijmegen Medical Centre (RUNMC). Although body donation to medical science contributes substantially to the quality of medical education, the ceremony was only the first time that the RUNMC publicly reciprocated the anatomical gift. By means of the monument the department of Anatomy endeavors to express gratitude for the gift of body donors and raise awareness among students to value the gift and treat donor bodies with the proper respect. Furthermore, the large attendance of bereaved at the unveiling ceremony, revealed another equally important meaning of the monument, which is the significance of the monument to the donor kin. The wish of a body donor has large implications for the way bereaved can take leave of the donor; there is limited time to bade the deceased farewell, the body will not be available for a funeral, and the donor kin stay behind empty handed without even a grave or ashes. Therefore the monument can be meaningful by facilitating the bereaved with a place of commemoration. The design of the monument anticipates on these multiple meanings and symbolisms by placing an old marble dissection table in the shape of an altar and fixing a bronze sculpture of a phoenix as symbol of imperishableness.

In a randomized, international study comparing rabbit antithymocyte globulin (TMG) and basiliximab (BAS) induction in renal transplant recipients at risk for delayed graft function or acute rejection (n=278), TMG was associated with less acute rejection at 1 year. This study analyzed outcomes stratified by standard criteria donor (SCD), extended criteria donor (ECD), and hypertensive donor. Data-capture limitations necessitated defining ECD as donor age more than 60 years or 50 to 60 years with hypertension and renal insufficiency. Seventy-five recipients received ECD-kidneys (28.4% TMG vs. 25.6% BAS, P=NS) and 203 recipients received SCD-kidneys (72.6% TMG vs. 74.4% BAS, P=NS). Recipients of an ECD or hypertensive donor-kidney had similar outcomes between treatment groups. Recipients of an SCD-kidney treated with TMG had less rejection (odds ratio [OR] 0.48). Recipients of a normotensive donor-kidney treated with TMG had less rejection (OR 0.56). Recipients of a normotensive, SCD-kidney treated with TMG had less rejection (OR 0.47) and death (OR 0.17) than their counterparts treated with BAS. Contrary to its perceived niche in recipients of ECD-kidneys, TMG was most beneficial in patients who received a normotensive, deceased SCD kidney.

Deceased-donor kidney transplantation (DDKT) from high-terminal creatinine donors is associated with lower graft survival. These kidneys may be considered for discarding, worsening the organ shortage crisis. Using time-zero biopsy for histologic evaluation of these kidneys, we identified those organs eligible for transplantation, seeking to achieve better graft utility with comparable outcomes. From April 2004 to April 2008, 55 patients underwent DDKT. A time-zero biopsy was used to examine glomerulosclerosis, interstitial fibrosis, tubular atrophy, and arteriolar narrowing. A scoring system was used to determine a discard. Twenty-five patients received DDKT from donors whose terminal creatinine levels were >2.0 mg/dL (high terminal creatinine, HTC group) and 30 from donors whose terminal creatinine levels were <2.0 mg/dL (low terminal creatinine, LTC group). Patients who accepted kidneys from HTC donors had shorter waiting times (P = .011) but a higher incidence of delayed graft function after transplantation (P < .001). Nonetheless, 5-year graft survival rates were similar between the two groups. With a time-zero biopsy for histologic evaluation, kidneys recovered from high-terminal creatinine donors can be transplanted to overcome the organ shortage while achieving reasonable graft survival.

Ethical issues regarding related and nonrelated living organ donors.

PubMed

Testa, Giuliano

2014-07-01

The ethics of the clinical practice of transplanting human organs for end-stage organ disease is a fascinating topic. Who is the "owner" of the transplantable organs of a deceased, brain-dead patient? Who should have a right to receive these organs? Who set the boundaries between a living donor's autonomy and a "paternalistic" doctor? What constitutes a proper consent? These questions are only some of the ethical issues that have been discussed in the last 60 years. All of these ethical issues are intensified by the fact that supply of human organs does not match demand, and that, as a consequence, living-donor organ transplantation is widely utilized. The aim of this article is not to be exhaustive but to present the general ethical principles of beneficence, nonmaleficence, and justice as applied to organ transplantation. Moreover, the topic of reimbursement for organ donation is also discussed.

[Reciprocal altruism--the resurrection of an old ethical principle in the Israeli organ transplant law].

PubMed

Lavee, Jacob

2014-01-01

The new Israeli Organ Transplant Law grants priority in organ allocation to candidates for transplantation who have registered as organ donors at least 3 years prior to being listed or have been Live organ donors or have a first degree relative who has been a deceased donor. This unique law resurrects the old ethical principle of reciprocal altruism in which each partner in society helps the other while he helps himself. The altruist benefits because in time he, in turn, is helped. The law aims to eliminate the "free riding" phenomenon of candidates for organ transplantation who do not accept brain death and therefore object to organ donation after death yet do not abstain from waiting for such donation. The morality of such behavior is discussed along with the ethical appraisal of its solution in the law, suggesting it to be just and fair.

Kidneys procured from the deceased hold great potential for expanding the donor pool. The aims of the present study were to investigate the post-transplant outcomes of renal allografts recovered from donors after cardiac death, to identify risk factors affecting the renal prognosis and to compare the long-term survival from donors after cardiac death according to the number of risk factors shown by expanded criteria donors. A total of 443 grafts recovered using an in situ regional cooling technique from 1983 to 2011 were assessed. To assess the combined predictive value of the significant expanded criteria donor risk criteria, the patients were divided into three groups: those with no expanded criteria donor risk factors (no risk), one expanded criteria donor risk factor (single-risk) and two or more expanded criteria donor risk factors (multiple-risk). Among the donor factors, age ≥50 years, hypertension, maximum serum creatinine level ≥1.5 mg/dL and a warm ischemia time ≥30 min were identified as independent predictors of long-term graft failure on multivariate analysis. Regarding the expanded criteria donors criteria for marginal donors, cerebrovascular disease, hypertension and maximum serum creatinine level ≥1.5 mg/dL were identified as significant predictors on univariate analysis. The single- and multiple-risk groups showed 2.01- and 2.40-fold higher risks of graft loss, respectively. Renal grafts recovered from donors after cardiac death donors have a good renal function with an excellent long-term graft survival. However, an increased number of expanded criteria donors risk factors increase the risk of graft loss. © 2016 The Japanese Urological Association.

CKD in disadvantaged populations.

Garcia-Garcia, Guillermo; Jha, Vivekanand

2015-02-01

The increased burden of CKD in disadvantaged populations is due to both global factors and population-specific issues. Low socioeconomic status and poor access to care contribute to health-care disparities and exacerbate the negative effects of genetic or biologic predisposition. Provision of appropriate renal care to these populations requires a two-pronged approach: expansion of the reach of dialysis through development of low-cost alternatives that can be practiced in remote locations, and implementation and evaluation of cost-effective prevention strategies. Kidney transplantation should be promoted by expansion of deceased-donor transplant programs and use of inexpensive, generic immunosuppressive drugs. The message of WKD 2015 is that a concerted attack against the diseases that lead to ESRD, by increased community outreach, better education, improved economic opportunity, and access to preventive medicine for those at highest risk, could end the unacceptable relationship between CKD and disadvantage in these communities.

Transplant centers in the Midwest Transplant Network began transplanting kidneys from A2 or A2B donors into blood group B and O patients in 1986. Since 1991, an OPTN/UNOS variance has permitted us to allocate these kidneys preferentially into B and O waiting list patients. With more than 10 years of experience we have noted the following: 1. Thirty-one percent more blood group B patients were transplanted by allocating them A2 or A2B kidneys from our deceased donors. 2. Ten-year graft survival for B recipients of an A2 or A2B kidney (72%) was equivalent to that for B recipients of a B kidney (69%). 3. Type B recipients of simultaneous pancreas-kidney transplants (n=4) also did well with A2 or A2B organs. 4. Non-A recipients were transplanted only when their anti-A IgG titer history was consistently low (< or =4). 5. Most (90%) blood group B patients had a low anti-A IgG titer history; whereas, only one-third of blood group O patients had a low titer history. 6. Neither ethnicity nor HLA class I sensitization level influenced the anti-A IgG titer history. 7. In an OPO with mostly (87%) white donors, nearly 20% of blood group A donors were A2. 8. Waiting time until transplantation was lower for B patients who received an A2 or A2B kidney than for those who received a B or O kidney. 9. Our OPO blood group B waiting list was reduced from 25 low PRA (<40%) B candidates in 1994 to 4 in July, 2004. 10. Blood group A candidates received 6.4% fewer transplants with our A2/A2B--> B allocation algorithm. 11. Minority patients were transplanted at the same rate when using the A2/A2B--> B allocation algorithm as when using the standard UNOS algorithm for allocating B and O kidneys--> B patients.

Orthotopic liver transplantation has become a routinely applied therapy for an expanding group of patients with end-stage liver disease. Shortage of organs has led centers to expand their criteria for the acceptance of marginal donors. There is current debate about the regulation and results of liver transplantation using marginal grafts. The study included data of all patients who received deceased donor liver grafts between March 2007 to December 2011. Patients with acute liver failure, living donor transplantation, split liver transplantation, and retransplantation were excluded. Early allograft dysfunction, primary nonfunction, patient survival, and incidence of surgical complications were measured. A total of 33 patients were enrolled in this study. There were 20 marginal and 13 nonmarginal grafts. The two groups were well matched regarding age, sex and indication of liver transplantation, model for end-stage liver disease score, technique of transplant, requirement of vascular reconstruction, warm ischemia time, blood loss, mean operative time, etc. In our study, posttransplant peak level of liver enzymes, international normalization ratio, and bilirubin were not statistically significant in the marginal and nonmarginal group. Wound infection occurred in 10 % of marginal compared with 7.7 % of nonmarginal graft recipients (p > 0.05). In the marginal group, the incidences of vascular complications, hepatic artery thrombosis (four), and portal vein thrombosis (one) were not statistically significant compared to the nonmarginal group. Acute rejection was observed in a total of seven patients (21.2 %)-five (25 %) in the marginal group and two (15.4 %) in the nonmarginal graft recipients. Primary nonfunction occurred in three (9.1 %) patients-two (10 %) in the marginal and one (7.7 %) in the nonmarginal group. Average patient survival for the whole group was 91 % at 1 week, 87.8 % at 3 months, and 84.8 % at 6 months. Because organ scarcity persists, additional pressure will build to use a greater proportion of the existing donor pool. The study, although small, clearly indicates that marginal livers can assure a normal early functional recovery after transplantation.

To evaluate the efficacy of tailored immunosuppressive regimens prescribed according to a risk stratification scoring system based on the number of HLA mismatches, donor source, panel-reactive antibodies (PRA), and repeat transplant. Patients in a retrospective cohort of 329 kidney transplantations performed from October 2004 to December 2005 were assigned scores of 0, 2, 4, or 6 with higher scores for > or =1 HLA mismatches, PRA > 10%, repeat transplant, and unrelated or deceased donor. Added scores of < or =4 comprised the low-risk group who received a Calcineurin inhibitor (CNI)-based regimen without induction, whereas a score > or = 6 denoted high risk including a CNI-based regimen with an interleukin-2 receptor antibody. The efficacy analysis compared the incidences of biopsy-proven acute rejection episodes (BPAR) at 1 year. Only 227 (69%) of 329 patients had a complete data set and 84 were excluded because they did not follow the prescribed protocol, yielding 113 low- and 30 high-risk patients in the final population. Low-risk patients had a mean PRA of 5.4%, living related donors in 68%, and primary transplants. High-risk patients had a mean PRA of 18.8% (range = 10%-97%), living nonrelated donors in 84%, four deceased donors, and four repeat transplants. The overall 1-year incidence of BPAR was 5.7%. No significant difference (P = .081) was observed in 1-year BPAR between the low- (4.5%) and high-risk (9.8%) groups. Likewise, no significant difference in the 1-year mean serum creatinine was observed according to the CNI. The mean creatinine was 1.12 for cyclosporine and 1.38 for tacrolimus treatment (P = .06) in the low-risk group and 1.08 for cyclosporine and 1.2 for tacrolimus (P = .61) in the high-risk cohort. There was no significant difference in acute rejection rates between the immunologically low- or high-risk patients using tailored immunosuppression, which was effective to minimize its occurrence with good renal function at 1 year.

Operative outcomes of adult living donor liver transplantation and deceased donor liver transplantation: a systematic review and meta-analysis.

2014-04-01

Living donor liver transplantation (LDLT) has emerged as an alternative to deceased donor liver transplantation (DDLT) because of the increasing number of patients waiting for liver transplantation (LT). However, whether it can achieve operative outcomes similar to those achieved with DDLT for adult patients remains controversial. We conducted this meta-analysis to compare the operative outcomes of LDLT and DDLT recipients. A literature search was performed to identify clinical controlled studies comparing LDLT and DDLT that were published before October 2013. Four perioperative outcomes [duration of the recipient operation (DRO), red blood cell (RBC) transfusion requirement, length of the hospital stay, and cold ischemia time (CIT)] and 5 postoperative complication outcomes (biliary complications, vascular complications, intra-abdominal bleeding, perioperative death, and retransplantation) were the main outcomes assessed. Nineteen studies with a total of 5450 patients were included in the meta-analysis. In comparison with DDLT, LDLT was associated with a significantly longer DRO and a shorter CIT. We found that biliary complications [odds ratio (OR) = 3.08, 95% confidence interval (CI) = 1.97-4.81, P < 0.001], vascular complications (OR = 2.16, 95% CI = 1.32-3.54, P = 0.002), and retransplantation (OR = 1.76, 95% CI = 1.09-2.83, P = 0.02) occurred more frequently for LDLT recipients, and the subgroup analysis indicated that the biliary complication rate decreased dramatically with greater LDLT experience. No significant difference was observed in RBC transfusion requirements, the lengths of hospital stays, intra-abdominal bleeding rates, or perioperative mortality between LDLT and DDLT recipients. In conclusion, LDLT is associated with a higher rate of surgical complications after transplantation. A reduction of postoperative complication rates can be achieved as centers gain greater experience with LDLT. However, LDLT is still an excellent alternative to DDLT because it facilitates access to LT. © 2014 American Association for the Study of Liver Diseases.

Prophylaxis Among Hepatitis B Core Antibody-positive Deceased-donor Liver Transplant Recipients: Hepatitis B Immunoglobulin Plus Oral Antiviral Agents Versus Antiviral Agents Alone: A Single-center Experience.

Hepatitis B core antibody immunoglobulin G seropositivity is evidence of past exposure to hepatitis B virus. Donor or recipient hepatitis B core antibody positivity may pose a risk of reactivation, especially early after liver transplant. Although most centers advocate using antiviral agents plus hepatitis B immunoglobulin, some have recently relied on antivirals only as prophylaxis after liver transplant. Here, we retrospectively investigated patient survival in hepatitis B core antibody-positive recipients, comparing those treated with antivirals plus hepatitis B immunoglobulin versus antivirals alone. After Internal Review Board approval, we reviewed medical records of deceased-donor liver transplant recipients between 1995 and 2013. Demographic characteristics, transplant indication, hepatitis B core antibody status, time to death, and type of posttransplant prophylaxis were recorded. We also recorded whether donors showed hepatitis B core antibody positivity. Patients who died within 30 days of liver transplant were excluded. There were 148 hepatitis B core antibody-positive recipients. Prophylaxis was given to 75 recipients after transplant: 8 (5%) received hepatitis B immunoglobulin, 22 (15%) received antivirals, and 45 (30%) received the combination. There were 34 deaths: 3 (38%) in hepatitis B immunoglobulin only, 3 (14%) in antiviral only, 8 (18%) in the combination, and 20 (27%) in no prophylaxis groups. One- and 5-year survival rates were similar for binary comparisons among prophylaxis groups (P > .05). Preliminary results support the current practice of using hepatitis B immunoglobulin plus antivirals for prophylaxis after liver transplant. The similar survival benefit with the combination versus antiviral agents alone suggests equal effectivity for prophylaxis posttransplant. However, a clear benefit of antivirals was not evident in our analysis. Future larger prospective studies are warranted to identify potential benefits of using antivirals alone as prophylaxis after liver transplant and to further clarify their role as the sole prophylactic regimen.

Our goal was to investigate wait times related to hepatitis C virus treatment with direct acting antivirals before versus after liver transplant at a single center as well as wait times for insurance approval for preemptive treatment with these agents after liver transplant. We retrospectively evaluated hepatitis C virus infections in transplant recipients of deceased liver donations in 2014 and 2015. Demographics, hepatocellular carcinoma incidence, Model for End-Stage Liver Disease scores, and transplant wait times were compared between patients treated before or after liver transplant. Wait times to approval of direct-acting antiviral treatment were evaluated in those untreated before transplant. During our study period, of 67 deceased-donor liver transplants, 21 patients received hepatitis C virus treatment pretransplant (treated group) and 46 patients were not treated pretransplant (untreated group). Twenty-five patients in the untreated group received hepatitis C virus-positive donations, with all in this group treated with direct-acting antivirals. We found no statistically significant differences regarding age, sex, race, donation after cardiac death, or incidence of hepatocellular carcinoma between groups. The treated group had a longer median wait time (287 vs 172 days; P = .02). Twelve of the 46 untreated patients (26.1%) developed biopsy-proven hepatitis C virus-related relapse (median 87 days; range, 55-383 days). Preemptive direct-acting antiviral therapy was initiated at a median of 81 days in the untreated group. Although treatment of hepatitis C virus before liver transplant is an attractive option to eliminate the risk of complications, it can limit the donor pool for recipients to uninfected donors, significantly increasing wait times in regions with large hepatitis C virus-positive donor pools. Allocation of Model for End-Stage Liver Disease score was not different between the treated and untreated groups. Insurance companies should revise their policies for rapid approval of preemptive direct-acting antiviral treatment after liver transplant.

Currently, there is no clear position regarding the donation of organs from donors with prostate carcinoma (CaP) in European countries, except Italy. The lengthening of life expectancy increases the probability of prostate cancer among potential organ donors. The concentration of prostate-specific antigen (PSA) >2 ng/mL at 60 years of age is related to the increasing possibility of identifying an advanced form of CaP. In recent years in Poland, the recommendation has been to determine tumor markers in potential donors. In the first year of the recommendation, 10% of potential male cadaveric donors were disqualified in West Pomerania, Poland, on the basis of elevated PSA levels (>10 ng/mL). To avoid reduction of the actual donor pool, each potential male donor reported to the center since January 2010 undergoes a routine histologic evaluation of the whole prostate, regardless of the PSA level, before organ implantation. In the study group (N = 52), histopathologic evaluation revealed 6 cases of CaP (12%). In CaP positive group Gleason score range from 2+2 to 3+4. In CaP donors PSA level have been noticed in range 1.79 ng/mL - 7.66 ng/mL. There was no correlation between histologically confirmed CaP and the PSA level. Copyright © 2016 Elsevier Inc.

Transplantation of kidneys from donor with arteriosclerosis seen on pre-implantation biopsy has not been well studied. We retrospectively evaluated 20 dual kidney transplant (DKT) and 28 single (SKT) kidney transplant recipients with >or=12 months follow-up from donors with moderate arteriosclerosis (>or=25% luminal diameter narrowing). Death censored graft survival was 100% and 79%, respectively (p = 0.0339). DKT recipients had significantly lower mean creatinine levels at one, three, six, and nine months and spent somewhat less time on the waiting list (181 +/- 160 vs. 318 +/- 306 d, p = 0.1429). DKT patients received kidneys from significantly older donors (64 +/- 7 vs. 54 +/- 11 yr; p = 0.0012), proportionately more expanded criteria donors (95% vs. 54%; p = 0.0029), and more donors with hypertension (81% vs. 48%, p = 0.0344) and death related to cerebrovascular accident (100% vs. 71%, p = 0.0143); however, more DKT kidneys underwent machine perfusion (95% vs. 57%, p = 0.0068). Baseline recipient variables were comparable between the two groups including age, race, gender, retransplantation, and HLA mismatch. Pre-implant biopsy was notable for similar frequencies of moderate interstitial fibrosis (10% vs. 14%, respectively) and glomerulosclerosis. Among recipients of deceased-donor kidneys with >25% arteriosclerosis, short-term outcomes after DKT were superior to that of SKT grafts. This approach may help to expand the donor-organ pool while optimizing outcomes.

Donor-derived infections due to multidrug-resistant bacteria are a growing problem in solid organ transplantation, and optimal management options are not clear. In a 2-year period, 30/214 (14%) recipients received an organ from 18/170 (10.5%) deceased donors with infection or colonization caused by a carbapenem-resistant gram-negative bacteria that was unknown at the time of transplantation. Among them, 14/30 recipients (47%) received a transplant from a donor with bacteremia or with infection/colonization of the transplanted organ and were considered at high risk of donor-derived infection transmission. The remaining 16/30 (53%) recipients received an organ from a nonbacteremic donor with colonization of a nontransplanted organ and were considered at low risk of infection transmission. Proven transmission occurred in 4 of the 14 high-risk recipients because donor infection was either not recognized, underestimated, or not communicated. These recipients received late, short or inappropriate posttransplant antibiotic therapy. Transmission did not occur in high-risk recipients who received appropriate and prompt antibiotic therapy for at least 7 days. The safe use of organs from donors with multidrug-resistant bacteria requires intra- and inter-institutional communication to allow appropriate management and prompt treatment of recipients in order to avoid transmission of infection. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

The use of octogenarian donors to increase the donor pool in liver transplantation (LT) is controversial because advanced donor age is associated with a higher risk of ischemic-type biliary lesions (ITBL). The aim of this study was to investigate retrospectively the role of a number of different pre-LT risk factors for ITBL in a selected population of recipients of octogenarian donor grafts. Between January 2003 and December 2013, 123 patients underwent transplantation at our institution with deceased donor grafts from donors of age ≥80 years. Patients were divided into 2 groups based on the presence of ITBL in the posttransplant course. Exclusion criteria were retransplantations, presence of vascular complications, and no availability of procurement liver biopsy. A total of 88 primary LTs were included, 73 (83.0%) with no posttransplant ITBLs and 15 (17.0%) with ITBLs. The median follow-up after LT was 2.1 years (range, 0.7-5.4 years). At multivariate analysis, donor hemodynamic instability (hazard ratio [HR], 7.6; P = 0.005), donor diabetes mellitus (HR, 9.5; P = 0.009), and donor age-Model for End-Stage Liver Disease (HR, 1.0; P = 0.04) were risk factors for ITBL. Transplantation of liver grafts from donors of age ≥80 years is associated with a higher risk for ITBL. However, favorable results can be achieved with accurate donor selection. Donor hemodynamic instability, a donor history of diabetes mellitus, and allocation to higher Model for End-Stage Liver Disease score recipient all increase the risk of ITBL and are associated with worse graft survival when octogenarian donors are used.

The kidney allocation score: methodological problems, moral concerns and unintended consequences.

2009-07-01

The growing disparity between the demand for and supply of kidneys for transplantation has generated interest in alternative systems of allocating kidneys from deceased donors. This personal viewpoint focuses attention on the Kidney Allocation Score (KAS) proposal promulgated by the UNOS/OPTN Kidney Committee. I identify several methodological and moral flaws in the proposed system, concluding that any iteration of the KAS proposal should be met with more skepticism than sanguinity.

The debate in Chile on organ donation revisited.

PubMed

Kottow Lang, Miguel Hugo

2016-08-29

The worldwide scarcity of cadaveric organs for transplants is on the rise, due in part to extended medical indications and longevity of chronic patients with organic insufficiencies. Chile has an extremely low donor rate of 6.7 per million. Although consent is presumed by law, and recently amended to include a “reciprocity principle”, nearly four million persons have expressed in writing their unwillingness to donate and, of those remaining, 53% of families have rejected donating the organs of their deceased. New proposals are urgently needed, even if some of them have previously been rejected: nonmaterial incentives, partial donations and unveiling anonymity to enhance personal ties between donors and recipients. Transparency, information and assistance are to be reinforced in order to regain trust in transplant procedures.

A stronger policy of organ retrieval from cadaveric donors: some ethical considerations

PubMed Central

Hamer, C; Rivlin, M

2003-01-01

Taking organs from dead people seems, prima facie, to raise fewer ethical complications than taking organs from other sources. There are, however, serious ethical problems in taking organs from the dead unless there is premortem evidence that this is what the deceased would have wanted, or at least, not have objected to. In this paper we will look at a "strong" opting out policy as proposed by John Harris. We will argue that people can be harmed after their death and that the posthumous removal of organs against their expressed wishes is one form that such harm might take. We also argue that Harris's claim that we show "equality of concern" between the donor and recipient requires too much. PMID:12796445

Improvement of the consent rate for solid organ donation from deceased donors is a key component of strategies applied in many countries aiming to increase the availability of organs for transplantation. Attitudes toward living and posthumous donation are favorable. Research shows that the outlook on organ donation and the degree of the willingness to become an organ donor are associated with a wide range of variables. The main objective of this study was to identify factors that influence the willingness to donate organs and the reasons for refusing consent. The study included 191 participants (135 female and 56 male) aged 16 to 61 years (mean age 26.86 ± 12.88). A cross-sectional study was conducted during educational meetings concerning organ donation that was addressed to students, teachers, and nurses. Survey tools included the Individual Questionnaire: Study of attitudes toward transplantation, consisting of 26 closed questions (with the consent of the Statistical Office in Krakow). In all, 97.4% of the respondents accepted transplantation from living donors, and 95.8% accepted deceased donations. Of the respondents, 78.5% agreed to posthumous life-saving organ donation. There was a significant difference between the respondents' sex, age, social group, place of living, and the reasons for their willingness to donate organs both posthumously and during their lifetime, as well as reasons for refusal. Our findings showed that the study group in general had favorable views on treatment involving transplantation and declared willingness to make a posthumous organ donation. These views vary depending on demographic variables. The education on the subject of organ and tissue donation has a positive impact on donation and transplantation rates.

2015-01-01

Background Kidney transplantation is the optimal therapy for the majority of patients with end-stage renal disease. However, the cost and health outcomes of transplantation have not been assessed in a middle-income nation with a low volume of transplantation, such as Malaysia. Aim and Methods This study used microcosting methods to determine the cost and health outcomes of living and deceased donor kidney transplantation in adult and pediatric recipients. The perspective used was from the Ministry of Health Malaysia. Cost-effectiveness measures were cost per life year (LY) and cost per quality-adjusted LYs. The time horizon was the lifetime of the transplant recipient from transplant to death. Results Records of 206 KT recipients (118 adults and 88 children) were obtained for microcosting. In adults, discounted cost per LY was US $8609(Malaysian Ringgit [RM]29 482) and US $13 209(RM45 234) for living-donor kidney transplant (LKT) and deceased donor kidney transplant (DKT), respectively, whereas in children, it was US $10 485(RM35 905) and US $14 985(RM51 317), respectively. Cost per quality-adjusted LY in adults was US $8826 (RM30 224) for LKT and US $13 592(RM46 546) for DKT. Total lifetime discounted costs of adult transplants were US $119 702 (RM409 921) for LKT, US $147 152 (RM503 922) for DKT. Total costs for pediatric transplants were US $154 841(RM530 252) and US $159 313(RM545 566) for the 2 categories respectively. Conclusions Both LKT and DKT are economically favorable for Malaysian adult and pediatric patients with ESRD and result in improvement in quality of life. PMID:27500211

Background and aims The shortage of organs for transplantation has led to increased use of organs procured from donors after cardiac death (DCD). The effects of cardiac death on the liver remain poorly understood, however. Using livers obtained from DCD versus donors after brain death (DBD), we aimed to understand how ischemia/reperfusion (I/R) injury alters expression of pro-inflammatory markers ceramides and influences graft leukocyte infiltration. Methods Hepatocyte inflammation, as assessed by ceramide expression, was evaluated in DCD (n = 13) and DBD (n = 10) livers. Allograft expression of inflammatory and cell death markers, and allograft leukocyte infiltration were evaluated from a contemporaneous independent cohort of DCD (n = 22) and DBD (n = 13) livers. Results When examining the differences between transplant stages in each group, C18, C20, C24 ceramides showed significant difference in DBD (p<0.05) and C22 ceramide (p<0.05) were more pronounced for DCD. C18 ceramide is correlated to bilirubin, INR, and creatinine after transplant in DCD. Prior to transplantation, DCD livers have reduced leukocyte infiltration compared to DBD allografts. Following reperfusion, the neutrophil infiltration and platelet deposition was less prevalent in DCD grafts while cell death and recipients levels of serum aspartate aminotransferase (AST) of DCD allografts had significantly increased. Conclusion These data suggest that I/R injury generate necrosis in the absence of a strong inflammatory response in DCD livers with an appreciable effect on early graft function. The long-term consequences of increased inflammation in DBD and increased cell death in DCD allografts are unknown and warrant further investigation. PMID:26863224

Assignment of C1q-binding HLA antibodies as unacceptable HLA antigens avoids positive CDC-crossmatches prior to transplantation of deceased donor organs.

Soon, a virtual crossmatch shall replace the complement-dependent cytotoxicity (CDC) allocation crossmatch in the Eurotransplant region. To prevent positive CDC-crossmatches in the recipient centre, careful definition of unacceptable antigens is necessary. For highly sensitized patients, this is difficult by CDC alone. Assignment of all antibodies detected by sensitive assays, however, could prevent organ allocation. To assess the usefulness of the Luminex C1q-assay to prevent positive CDC-crossmatches, all CDC-crossmatches performed prior to deceased kidney transplantation in a 16-month-period were reviewed. Sera causing positive crossmatches were investigated by the C1q-assay. 31 out of 1432 crossmatches (2.2%) were positive. Sera involved in 26 positive crossmatches were available. C1q-binding donor-specific antibodies were detected in 19 sera (73.1%). The other sera were from recipients without any HLA antibodies detectable by CDC or common solid phase assays. Three patients had known Non-HLA antibodies causing positive CDC-results. Four crossmatches were only weak positive. Therefore, avoidance of donors with HLA antigens against whom C1q-binding antibodies were detected would have prevented all positive crossmatches due to HLA antibodies. Provided that all HLA specificities against which antibodies are detected by the Luminex C1q-assay are considered as unacceptable antigens, CDC-crossmatches prior to transplantation might safely be omitted in many patients. They should be maintained in highly immunized patients, however, for whom assignment of all C1q-positive antibodies as unacceptable antigens could lead to a significant delay or even prevention of transplantation.

[The history of kidney transplantation].

2016-10-01

The history of kidney transplantation is a history of many unsuccessful efforts and setbacks, but also the history of perseverance, pioneering spirit, and steadfast courage. The first successful transplantation of a dog kidney was done by the Austrian Emerich Ullmann (1861-1937) in 1902. The kidney was connected to the carotid artery of the dog and the ureter ended freely. The organ produced urine for a couple of days before it died. In 1909, there were efforts to transplant human kidneys from deceased patients to monkeys and in the following year the first xenotransplantation in humans was completed. Different kinds of donors were tried: dogs, monkeys, goats and lambs, all without success. In 1939, the first transplantation from a deceased human donor was done by the Russion Yurii Voronoy, the patient survived for only a couple of days, and the organ never worked. In 1953, the first temporarily successful transplantation of a human kidney was performed by Jean Hamburger in Paris. A 16-year-old boy received the kidney of his mother as living donor transplantation. Then in 1954, a milestone was made with the first long-term successful kidney transplantation by Joseph Murray: the transplantation was done between monozygotic twins; the organ survived for 8 years. For his efforts in kidney transplantation, Murray was honored with the Nobel Prize in medicine in 1990. In 1962, the first kidney transplantation between genetically nonrelated patients was done using immunosuppression and in 1963 the first kidney transplantation in Germany was done by Reinhard Nagel and Wilhelm Brosig in Berlin. The aim of this article is to present the history of kidney transplantation from the beginning until today.

Our organ procurement organization (OPO) evaluated the clinical and financial efficacy of point-of-care testing (POCT) in management of our deceased organ donors. Before we implemented point-of care testing with the i-STAT into routine clinical donor management, we compared the i-STAT result with the result from the respective donor hospital lab (DHL) for certain analytes on 15 consecutive donors in our OPO from 26 March to 14 May 2001. The financial impact was studied by reviewing 77 donors from July 2001 to March 2002. There was a strong correlation for each analyte between the POC and DHL test results with r-values as follows: pH 0.86; PCO2 = 0.96; PO2 = 0.98; sodium = 0.98; potassium = 0.95; chloride = 0.94; BUN = 0.98; glucose = 0.92; haematocrit = 0.87 and creatinine = 0.95. Since our OPO coordinators began using i-STAT in their routine clinical management of organ donors, they can now more quickly maximize oxygenation and fluid management of the donor and make extra-renal placement calls sooner. Finally, since we are no longer being billed for the testing performed on the i-STAT, average financial savings to our OPO are US dollars 733 per case. Point-of-care testing in management of our OPO donors provides a result that is equivalent to that of the donor hospital lab, has quicker turn-around time than the donor hospital laboratory, allowing more immediate clinical management decisions to be made so that extra-renal offers may begin sooner.

Despite the potential for altruistic nondirected donors (NDDs) to trigger multiple transplants through nonsimultaneous transplant chains, concerns exist that these chains siphon NDDs from the deceased donor wait list and that donors within chains might not donate after their partner receives a transplant. To determine the number of transplantations NDDs trigger through chains. Retrospective review of large, multicenter living donor-recipient database. Fifty-seven US transplant centers contributing donor-recipient pairs to the database. The NDDs initiating chain transplantation. Number of transplants per NDD. Seventy-seven NDDs enabled 373 transplantations during 46 months starting February 2008. Mean chain length initiated by NDDs was 4.8 transplants (median, 3; range, 1-30). The 40 blood type O NDDs triggered a mean chain length of 6.0 (median, 4; range, 2-30). During the interval, 66 of 77 chains were closed to the wait list, 4 of 77 were ongoing, and 7 of 77 were broken because bridge donors became unavailable. No chains were broken in the last 15 months, and every recipient whose incompatible donor donated received a kidney. One hundred thirty-three blood type O recipients were transplanted. This large series demonstrates that NDDs trigger almost 5 transplants on average, more if the NDD is blood type O. There were more blood type O recipients than blood type O NDDs participating. The benefits of transplanting 373 patients and enabling others without living donors to advance outweigh the risk of broken chains that is decreasing with experience. Even 66 patients on the wait list without living donors underwent transplantation with living-donor grafts at the end of these chains.

Despite its superior outcomes relative to chronic dialysis and deceased donor kidney transplantation, live donor kidney transplantation (LDKT) is less likely to occur in minorities, older adults, and poor patients than in those who are white, younger, and have higher household income. In addition, there is considerable geographic variability in LDKT rates. Concomitantly, in recent years, the rate of living kidney donation (LKD) has stopped increasing and is declining, after decades of consistent growth. Particularly noteworthy is the decline in LKD among black, younger, male, and lower-income adults. The Live Donor Community of Practice within the American Society of Transplantation, with financial support from 10 other organizations, held a Consensus Conference on Best Practices in Live Kidney Donation in June 2014. The purpose of this meeting was to identify LKD best practices and knowledge gaps that might influence LDKT, with a focus on patient and donor education, evaluation efficiencies, disparities, and systemic barriers to LKD. In this article, we discuss trends in LDKT/LKD and emerging novel strategies for attenuating disparities, and we offer specific recommendations for future clinical practice, education, research, and policy from the Consensus Conference Workgroup focused on disparities.

The human patient simulators that are currently used in multidisciplinary operating room team training scenarios cannot simulate surgical tasks because they lack a realistic surgical anatomy. Thus, they eliminate the surgeon's primary task in the operating room. The surgical trainee is presented with a significant barrier when he or she attempts to suspend disbelief and engage in the scenario. To develop and test a simulation-based operating room team training strategy that challenges the communication abilities and teamwork competencies of surgeons while they are engaged in realistic operative maneuvers. This pre-post educational intervention pilot study compared the gains in teamwork skills for midlevel surgical residents at Wake Forest Baptist Medical Center after they participated in a standardized multidisciplinary team training scenario with 3 possible levels of surgical realism: (1) SimMan (Laerdal) (control group, no surgical anatomy); (2) "synthetic anatomy for surgical tasks" mannequin (medium-fidelity anatomy), and (3) a patient simulated by a deceased donor (high-fidelity anatomy). Participation in the simulation scenario and the subsequent debriefing. Teamwork competency was assessed using several instruments with extensive validity evidence, including the Nontechnical Skills assessment, the Trauma Management Skills scoring system, the Crisis Resource Management checklist, and a self-efficacy survey instrument. Participant satisfaction was assessed with a Likert-scale questionnaire. Scenario participants included midlevel surgical residents, anesthesia providers, scrub nurses, and circulating nurses. Statistical models showed that surgical residents exposed to medium-fidelity simulation (synthetic anatomy for surgical tasks) team training scenarios demonstrated greater gains in teamwork skills compared with control groups (SimMan) (Nontechnical Skills video score: 95% CI, 1.06-16.41; Trauma Management Skills video score: 95% CI, 0.61-2.90) and equivalent gains in teamwork skills compared with high-fidelity simulations (deceased donor) (Nontechnical Skills video score: 95% CI, -8.51 to 6.71; Trauma Management Skills video score: 95% CI, -1.70 to 0.49). Including a surgical task in operating room team training significantly enhanced the acquisition of teamwork skills among midlevel surgical residents. Incorporating relatively inexpensive, medium-fidelity synthetic anatomy in human patient simulators was as effective as using high-fidelity anatomies from deceased donors for promoting teamwork skills in this learning group.

Solid organ transplant recipients have a higher frequency of tuberculosis (TB) than the general population, with mortality rates of approximately 30%. Although donor-derived TB is reported to account for <5% of TB in solid organ transplants, the source of Mycobacterium tuberculosis infection is infrequently determined. We report 3 new cases of pulmonary TB in lung transplant recipients attributed to donor infection, and review the 12 previously reported cases to assess whether cases could have been prevented and whether any cases that might occur in the future could be detected and investigated more quickly. Specifically, we evaluate whether opportunities existed to determine TB risk on the basis of routine donor history, to expedite diagnosis through routine mycobacterial smears and cultures of respiratory specimens early post transplant, and to utilize molecular tools to investigate infection sources epidemiologically. On review, donor TB risk was present among 7 cases. Routine smears and cultures diagnosed 4 asymptomatic cases. Genotyping was used to support epidemiologic findings in 6 cases. Validated screening protocols, including microbiological testing and newer technologies (e.g., interferon-gamma release assays) to identify unrecognized M. tuberculosis infection in deceased donors, are warranted. © 2014 John Wiley & Sons A/S.

HIV-infected (HIV+) donor organs can be transplanted into HIV+ recipients under the HIV Organ Policy Equity (HOPE) Act. Quantifying HIV+ donor referrals received by organ procurement organizations (OPOs) is critical for HOPE Act implementation. We surveyed the 58 USA OPOs regarding HIV+ referral records and newly discovered HIV+ donors. Using data from OPOs that provided exact records and CDC HIV prevalence data, we projected a national estimate of HIV+ referrals. Fifty-five (95%) OPOs reported HIV+ referrals ranging from 0 to 276 and newly discovered HIV+ cases ranging from 0 to 10 annually. Six OPOs in areas of high HIV prevalence reported more than 100 HIV+ donor referrals. Twenty-seven (47%) OPOs provided exact HIV+ referral records and 28 (51%) OPOs provided exact records of discovered HIV+ cases, totaling 1450 HIV+ referrals and 39 discovered HIV+ donors in the prior year. These OPOs represented 67% and 59% of prevalent HIV cases in the USA; thus, we estimated 2164 HIV+ referrals and 66 discovered HIV+ cases nationally per year. OPOs reported a high volume of HIV+ referrals annually, of which a subset will be medically eligible for donation. Particularly in areas of high HIV prevalence, OPOs require ongoing support to implement the HOPE Act. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Racial disparities in paediatric kidney transplantation.

Transplantation is the preferred treatment for children with end-stage kidney disease (ESKD). Pre-emptive transplants, those from live donors and with few human leukocyte antigen (HLA) mismatches provide the best outcomes. Studies into disparities in paediatric transplantation to date have not adequately disentangled different transplant types. We studied a retrospective cohort of 823 patients aged <18 years who started renal replacement therapy (RRT) in Australia 1990-2011, using the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA). The primary outcomes were time to first kidney transplant and kidney donor type (deceased or living), analysed using competing risk regression. Caucasian patients were most likely to receive any transplant, due largely to disparities in live donor transplantation. No Indigenous patients received a pre-emptive transplant. Indigenous patients were least likely to receive a transplant from a live donor (sub-hazard ratio 0.41, 95 % confidence interval 0.20-0.82, compared to Caucasians). Caucasian recipients had fewer HLA mismatches, were less sensitised and were more likely to have kidney diseases that could be diagnosed early or progress slowly. Caucasian paediatric patients are more likely to receive optimum treatment--a transplant from a living donor and fewer HLA mismatches. Further work is required to identify and address barriers to live donor transplantation among minority racial groups.

An investigation into mature adults' attitudinal reluctance to register as organ donors.

Mature adults (age 50-64) make up a large proportion of organ transplant recipients, and waiting list candidates yet are underrepresented in terms of actual donors. Understanding the reasons why mature adults fail to register as deceased organ donors is critical in achieving the goal of increasing the actionable supply of organs available for transplant. Conceptual models propose certain factors such as bodily integrity, ick (i.e., disgust), jinx (i.e., superstition), medical mistrust, salience, self-efficacy, and stake are associated with organ donation registration attitudes. Moreover, the age myth, or the belief that one's age prevents them from becoming an organ donor, was examined among mature adults between the ages of 50-64. An online survey was disseminated to mature adults (N=709). Results indicated jinx, salience, self-efficacy, and stake each predicted organ donation attitudes among mature adults. Moreover, results indicated that age myth accounted for attitudes toward registering as an organ donor among non-registered mature adults after controlling for non-cognitive and vested interest constructs.

The aim of this paper is to look into the factors influencing Malaysian Muslims' decision to become deceased organ donors in Malaysia. We approached 900 Malaysian Muslims and 779 participated in our survey, conducted in Kuala Lumpur and its suburb. We examined their willingness to become donors and the willing donors were asked why they did not pledge to become donors. Non-donors were asked why they refuse to become donors. The survey found the main reason for Malaysian Muslims not pledging their organs was due to their lack of information on organ donation and/or their lack of confidence in the government's ability to properly administer organ donation procedures. Another interesting finding is that religion is not a main deterrent to organ donation. The survey suggests that Malaysia can explore many ways to encourage organ donation without having to resort to the highly controversial financial incentive option. A key to Malaysia's success or failure to increase organ donation rate lies in its ability to persuade its Muslim population (its largest population) to donate organs. This can be done by adopting a segmented, focused, and highly localized form of public education and by leveraging on existing networks involving local religious and community leaders as well as government and non-governmental institutions.

Liver transplantation (LT) is an established therapeutic modality for patients with end-stage liver disease. The use of marginal donors has become more common worldwide due to the sharp increase in recipients, with a consequent shortage of suitable organs. We analyzed our single-center experience over the last 8 years in LT to evaluate the outcomes of using so-called "marginal donors." We retrospectively analyzed the database of all LTs performed at our institution from 2009 to 2017. Only patients undergoing deceased-donor LTs were analyzed. Marginal grafts were defined as livers from donors >60 years of age, livers from donors with serum sodium levels >155 mEq, graft steatosis >30%, livers with cold ischemia time ≥12 hours, livers from donors who were hepatitis B or C virus positive, livers recovered from donation after cardiac death, and livers split between 2 recipients. Patients receiving marginal grafts (marginal group) were compared with patients receiving standard grafts (standard group). A total of 106 patients underwent deceased-donor LT. There were 55 patients in the standard group and 51 patients in the marginal group. There were no significant differences in terms of age, sex, Model for End-Stage Liver Disease score, underlying liver disease, presence of hepatocellular carcinoma, and hospital stay between the 2 groups. Although the incidence of acute cellular rejection, cytomegalovirus infection, and postoperative complications was similar between the 2 groups, the incidence of early allograft dysfunction was higher in the marginal group. With a median follow-up of 26 months, the 1-, 3-, and 5-year overall and graft (death-censored) survivals in the marginal group were 85.5%, 75%, and 69.2% and 85.9%, 83.6%, and 77.2%, respectively. Patient overall survival and graft survival (death-censored) were significantly lower in the marginal group (P = .023 and P = .048, respectively). On multivariate analysis, receiving a marginal graft (hazard ratio [HR], 4.862 [95% confidence interval (CI), 1.233-19.171]; P = .024) and occurrence of postoperative complications (HR, 4.547 [95% CI, 1.279-16.168]; P = .019) were significantly associated with worse patient overall survival. Also, when factors associated with marginal graft were analyzed separately, graft steatosis >30% was independently associated with survival (HR, 5.947 [95% CI, 1.481-23.886]; P = .012). Patients receiving marginal grafts showed lower but acceptable overall survival and graft survival. However, because graft steatosis >30% was independently associated with worse survival, caution must be exercised when using this type of marginal graft by weighing the risk and benefits.

Death rates from drug overdoses have nearly doubled since 2003, with over 47 000 deaths in 2014. This is largely attributable to the opioid epidemic. If the unfortunate deaths of otherwise healthy people have yielded an increase in organ donors, then this might serve as perhaps the only comforting factor among this tragic and unnecessary loss of life. In this viewpoint, we present data from the Organ Procurement and Transplantation Network (OPTN) that show how the greatest relative increases in the mechanism of death among deceased donors from 2003 to 2014 were drug overdoses. Unfortunately, despite the absolute increase in the number of donors who died from a drug overdose, the mean organ yield was significantly lower than in other categories, in part due to concerns about disease transmission. In this paper, we present data on the changes in donation from donors with a drug overdose as a result of the opioid epidemic and discuss the need to educate transplant candidates and their physicians about the low risk of disease transmission compared to the greater risk of dying on a transplant waitlist.

In the majority of countries, there is a shortage of donor corneas for corneal transplantations. This study investigated the impact of organ transplantation scandals on corneal donation rate at the University Hospital Tübingen. Each deceased patient was considered as a potential corneal donor. An ophthalmic resident handled with stable methods of procedures the corneal donor procurement from 2009 to 2015. The rates of corneal donation were examined and analyzed. Among the 5712 hospital deaths, consent for corneal donation was obtained in 711 cases. The mean annual corneal donation rate was 12.4%. Since 2009, the donation rate per year could be increased with exception of 2013 and 2015. In the end of 2012 and 2014 two huge organ donation scandals were known in Germany. In the following years 2013 and 2015 corneal donation rate decreased significantly ( P =0.0181 and P =0.0006). We concluded that transplantation scandals have a significant impact on corneal donation rate. Improving professional's performance through full transparency and honesty is very important to earn trust of potential donors and their families.

Rosso, Fernando; Pineda, Juan C; Sanz, Ana M; Cedano, Jorge A; Caicedo, Luis A

Dengue fever is a vector-transmitted viral infection. Non-vectorial forms of transmission can occur through organ transplantation. We reviewed medical records of donors and recipients with suspected dengue in the first post-transplant week. We used serologic and molecular analysis to confirm the infection. Herein, we describe four cases of dengue virus transmission through solid organ transplantation. The recipients had positive serology and RT-PCR. Infection in donors was detected through serology. All cases presented with fever within the first week after transplantation. There were no fatal cases. After these cases, we implemented dengue screening with NS1 antigen detection in donors during dengue outbreaks, and no new cases were detected. In the literature review, additional cases had been published through August 2017. Transmission of Dengue virus can occur through organ donation. In endemic regions, it is important to suspect and screen for dengue in febrile and thrombocytopenic recipients in the postoperative period. Copyright © 2018 Sociedade Brasileira de Infectologia.

Introduction Even after placement on the deceased donor waitlist, there are racial disparities in access to kidney transplant. The association between hospitalization, a proxy for health while waitlisted, and disparities in kidney transplant has not been investigated. Methods We used United States Renal Data System Medicare-linked data on waitlisted End-Stage Renal Disease (ESRD) patients between 2005 and 2009 with continuous enrollment in Medicare Parts A & B (n=24 581) to examine the association between annual hospitalization rate and odds of receiving a deceased donor kidney transplant. We used multi-level mixed effects models to estimate adjusted odds ratios (aOR), controlling for individual-, transplant center-, and organ procurement organization-level clustering. Results Blacks and Hispanics were more likely than whites to be hospitalized for circulatory system or endocrine, nutritional, and metabolic diseases (p<0.001). After adjustment, compared to individuals not hospitalized, patients who were hospitalized frequently while waitlisted were less likely to be transplanted (>2 vs. 0 hospitalizations/year aOR=0.57, p<0.001). Though blacks and Hispanics were more likely to be hospitalized than whites (p<0.001), adjusting for hospitalization did not change estimated racial/ethnic disparities in kidney transplantation. Conclusions Individuals hospitalized while waitlisted were less likely to receive a transplant. However, hospitalization does not account for the racial disparity in kidney transplantation after waitlisting. PMID:26845307

Intrahepatic arterioportal fistula (IAPF) is a rare cause of portal hypertension that is often difficult to treat with interventional radiology or surgery. Liver transplantation for IAPF is extremely rare. We report a case of bilateral diffuse IAPF with severe portal hypertension requiring deceased donor liver transplantation (DDLT). A 51-year-old woman with no past medical history was admitted to another hospital complaining of abdominal distension and marasmus. A computed tomography scan and digital subtraction angiography indicated a massive pleural effusion, ascites, and a very large IAPF. Several attempts of interventional embolization of the feeding artery failed to ameliorate arterioportal shunt flow. As ruptures of the esophageal varices became more frequent, hepatic encephalopathy worsened. After repeated, uncontrollable attacks of hepatic coma, the patient was referred to our facility for further treatment. Surgical approaches to IAPF other than liver transplantation were challenging because of diffuse collateralization; therefore, we placed the patient on the national waiting list for DDLT. Although her Model for End-Stage Liver Disease score was relatively low, she received a DDLT 2 months after the waiting period. The postoperative course was uneventful, and the patient was discharged 44 days after her transplant. Liver transplantation may be a valid treatment option for uncontrollable IAPF with severe portal hypertension. © 2016 The Authors Hepatology Research published by John Wiley & Sons Australia, Ltd on behalf of Japan Society of Hepatology.

Replacement of pancreatic β-cells through deceased donor islet transplantation is a proven therapy for preventing recurrent life-threatening hypoglycemia in type 1 diabetes. Although near-normal glucose levels and insulin independence can be maintained for many years following successful islet transplantation, restoration of normal functional β-cell mass has remained elusive. It has recently been proposed that dedifferentiation/plasticity towards other endocrine phenotypes may play an important role in stress-induced β-cell dysfunction in type 2 diabetes. Here we report loss of end-differentiated β-cell phenotype in 2 intraportal islet allotransplant recipients. Despite excellent graft function and sustained insulin independence, all examined insulin-positive cells had lost expression of the end-differentiation marker, urocortin-3, or appeared to co-express the α-cell marker, glucagon. In contrast, no insulin + /urocortin-3 - cells were seen in nondiabetic deceased donor control pancreatic islets. Loss of end-differentiated phenotype may facilitate β-cell survival during the stresses associated with islet isolation and culture, in addition to sustained hypoxia following engraftment. As further refinements in islet isolation and culture are made in parallel with exploration of alternative β-cell sources, graft sites, and ultimately fully vascularized bioengineered insulin-secreting microtissues, differentiation status immunostaining provides a novel tool to assess whether fully mature β-cell phenotype has been maintained. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

Split liver transplantation increases the number of grafts available for transplantation. Pre-recovery assessment of liver graft volume is essential for selecting suitable recipients. The purpose of this study was to determine the ability and feasibility of constructing a 3-D model to aid in surgical planning and to predict graft weight prior to an in situ division of the donor liver. Over 11 months, 3-D volumetric reconstruction of 4 deceased donors was performed using Pathfinder Scout© liver volumetric software. Demographic, laboratory, operative, perioperative and survival data for these patients along with donor demographic data were collected prospectively and analyzed retrospectively. The average predicted weight of the grafts from the adult donors obtained from an in situ split procedure were 1130 g (930-1458 g) for the extended right lobe donors and 312 g (222-396 g) for left lateral segment grafts. Actual adult graft weight was 92% of the predicted weight for both the extended right grafts and the left lateral segment grafts. The predicted and actual graft weights for the pediatric donors were 176 g and 210 g for the left lateral segment grafts and 308 g and 280 g for the extended right lobe grafts, respectively. All grafts were transplanted except for the right lobe from the pediatric donors due to the small graft weight. On-site volumetric assessment of donors provides useful information for the planning of an in situ split and for selection of recipients. This information may expand the donor pool to recipients previously felt to be unsuitable due to donor and/or recipient weight.

Most kidneys from potential elderly circulatory death (DCD) donors are declined. We report single center outcomes for kidneys transplanted from DCD donors over 70 years old, using preimplantation biopsy Remuzzi grading to inform implantation as single or dual transplants. Between 2009 and 2012, 43 single transplants and 12 dual transplants were performed from elderly DCD donors. Remuzzi scores were higher for dual than single implants (4.4 vs. 3.4, p < 0.001), indicating more severe baseline injury. Donor and recipient characteristics for both groups were otherwise similar. Early graft loss from renal vein thrombosis occurred in two singly implanted kidneys, and in one dual-implanted kidney; its pair continued to function satisfactorily. Death-censored graft survival at 3 years was comparable for the two groups (single 94%; dual 100%), as was 1 year eGFR. Delayed graft function occurred less frequently in the dual-implant group (25% vs. 65%, p = 0.010). Using this approach, we performed proportionally more kidney transplants from elderly DCD donors (23.4%) than the rest of the United Kingdom (7.3%, p < 0.001), with graft outcomes comparable to those achieved nationally for all deceased-donor kidney transplants. Preimplantation biopsy analysis is associated with acceptable transplant outcomes for elderly DCD kidneys and may increase transplant numbers from an underutilized donor pool. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

There is great demand for transplant kidneys for the treatment of end-stage kidney disease patients. To expand the donor pool, organs from older and comorbid brain death donors, so-called expanded criteria donors (ECD), as well as donation after circulatory death donors, are considered for transplantation. However, the quality of these organs may be inferior to standard donor organs. A major issue affecting graft function and survival is ischemia/reperfusion injury, which particularly affects kidneys from deceased donors. The development of hypothermic machine perfusion has been introduced in kidney transplantation as a preservation technique and has improved outcomes in ECD and marginal organs compared to static cold storage. Normothermic machine perfusion (NMP) is the most recent evolution of perfusion technology and allows assessment of the donor organ before transplantation. The possibility to control the content of the perfusion fluid offers opportunities for damage control and reparative therapies during machine perfusion. Mesenchymal stromal cells (MSC) have been demonstrated to possess potent regenerative properties via the release of paracrine effectors. The combination of NMP and MSC administration at the same time is a promising procedure in the field of transplantation. Therefore, the MePEP consortium has been created to study this novel modality of treatment in preparation for human trials. MePEP aims to assess the therapeutic effects of MSC administered ex vivo by NMP in the mechanisms of injury and repair in a porcine kidney autotransplantation model.

Pancreas transplantation is a treatment for advanced type 1 diabetes and offers significant improvement in quality of life. Recent advances in surgical techniques and immunosuppression regimes lead to good outcomes. However, despite significant higher rates of multiorgan donors in Brazil, pancreas transplantation seems to have remained stable. This study aimed to investigate the acceptance rate of potential pancreas donors in the past 10 years in São Paulo State. We retrospectively evaluated potential pancreas donors characteristics and its acceptance rate in São Paulo State in the past 10 years. We divided this period into 2 eras: 1st era from January 2003 to January 2008; and 2nd era from January 2008 to January 2013. Data were obtained from São Paulo's government official website. During the whole period, 5,005 deceased donors of all ages were available for pancreas transplantation. According to eras, we had 1,588 donors in the 1st and 3,417 in the 2nd era. In the 2nd era, donors >49 years old were significantly more common (P < .001). Blood test abnormalities, donor comorbidities, and high dosage of vasopressors also were significantly higher in the 2nd era. Rate of graft acceptance had a significant decrease in the 2nd era, from 46.4% to 25% (P < .05). Despite greater organ availability, pancreas transplantations performed in São Paulo State remained stable. Rate of graft acceptance is dramatically lower in more recent years.

The Organ Procurement and Transplantation Network (OPTN) has formulated criteria for the selection of donors for intestinal transplantation. To date, however, no study has correlated histologic findings of intestinal injury with the OPTN criteria. We aimed to describe histopathologic and molecular features of allograft injury in relation to donor conditions defined by the OPTN criteria. Graft histology (Park Score), Claudin-3 staining, systemic inflammatory markers (C-reactive protein/lipopolysaccharide-binding protein) and expression of heat shock protein 70, heme oxygenase 1, and interleukin 6 were evaluated in multiorgan deceased donors (donation after brain death [DBD] and donation after cardiac death [DCD]). Ninety-seven samples (52 jejunum/45 ileum) were recovered from 59 donors (46 DBD/13 DCD). The OPTN criterion cold ischemia time correlated with histologic injury (Park score) to which the jejunum appeared more susceptible than the ileum. Claudin-3 staining was higher, and heat shock protein 70 expression lower in donors meeting the OPTN criteria compared with donors not meeting the criteria and in DBD versus DCD. In DBD donors, interleukin 6 expression was higher compared with DCD donors and inversely related to C-reactive protein. Our multiparameter analysis suggests that the OPTN criteria can be discriminative concerning intestinal graft quality. Our data suggest that DCD intestinal allografts are qualitatively inferior and that the jejunum is more sensitive to ischemia than the ileum. Copyright © 2014 Elsevier Inc. All rights reserved.

Brazilian Healthcare Professionals: A Study of Attitudes Toward Organ Donation.

Araujo, C; Siqueira, M

2016-12-01

Healthcare professionals have a crucial role in organ donation and transplantation processes. Their attitude toward organ donation can affect public opinion and the donation decision made by deceased donors' relatives. The objectives of the study were to analyze the attitude of medical and nursing personnel toward deceased organ donation in two hospitals in Rio de Janeiro, Brazil, and the factors that can affect this attitude. A random sample (n = 162) was selected from the population of nurses and physicians in the hospitals analyzed. The sample was stratified by age, sex, marital status, religion, professional category, and educational level. A validated questionnaire addressing psychosocial aspects of organ donation was used to evaluate attitudes. The χ 2 and Mann-Whitney U tests were applied for statistical analysis. Of personnel surveyed, 86.4% (n = 140) were in favor of deceased organ donation, whereas 11.1% (n = 18) were not sure and 2.5% (n = 4) were against. The favorable attitude was related to the following aspects: (1) educational level, (2) having spoken with family members about organ donation, (3) having a chronic disease, (4) favorable attitude of one's family, (5) belief that organ donation can save lives, (6) concerns about body manipulation, illegal trade of organs, and organ donation being against God's will, (7) feeling proud of working with organ donation/transplantation, (8) self-assessment of experience and knowledge in organ donation/transplantation activities (P < .05). Deceased organ donation is well accepted among the healthcare professionals surveyed, and the attitude is affected by socio-personal variables. Copyright © 2016 Elsevier Inc. All rights reserved.

Living donor liver transplantation has become a cornerstone for the treatment of children with end-stage hepatic dysfunction, especially within populations or countries with low rates of organ utilization from deceased donors. The objective is to report our experience with 185 living donors operated on by a team pediatric surgeons in a tertiary center for pediatric liver transplantation. Retrospective analysis of medical records of donors of hepatic grafts for transplant undergoing surgery between June 1998 and March 2013. Over the last 14 years, 185 liver transplants were performed in pediatric recipients of grafts from living donors. Among the donors, 166 left lateral segments (89.7%), 18 left lobes without the caudate lobe (9.7%) and 1 right lobe (0.5%) were harvested. The donor age ranged from 16 to 53 years, and the weight ranged from 47 to 106 kg. In 10 donors, an additional graft of the donor inferior mesenteric vein was harvested to substitute for a hypoplastic recipient portal vein. The transfusion of blood products was required in 15 donors (8.1%). The mean hospital stay was 5 days. No deaths occurred, but complications were identified in 23 patients (12.4%): 9 patients experienced abdominal pain and severe gastrointestinal symptoms and 3 patients required reoperations. Eight donors presented with minor bile leaks that were treated conservatively, and 3 patients developed extra-peritoneal infections (1 wound collection, 1 phlebitis and 1 pneumonia). Eight grafts (4.3%) showed primary dysfunction resulting in recipient death (3 cases of fulminant hepatitis, 1 patient with metabolic disease, 1 patient with Alagille syndrome and 3 cases of biliary atresia in infants under 1 year old). There was no relation between donor complications and primary graft dysfunction (P=0.6). Living donor transplantation is safe for the donor and presents a low morbidity. The donor surgery may be performed by a team of trained pediatric surgeons. © 2014.

In 1958 Francis Moore described the orthotopic liver transplantation technique in dogs. In 1963, Starzl et al. performed the first liver transplantation. In the first five liver transplantations no patient survived more than 23 days. In 1967, stimulated by Calne who used antilymphocytic serum, Starzl began a successful series of liver transplantation. Until 1977, 200 liver transplantations were performed in the world. In that period, technical problems were overcome. Roy Calne, in 1979, used the first time cyclosporine in two patients who had undergone liver transplantation. In 1989, Starzl et al. reported a series of 1,179 consecutives patients who underwent liver transplantation and reported a survival rate between one and five years of 73% and 64%, respectively. Finally, in 1990, Starzl et al. reported successful use of tacrolimus in patents undergoing liver transplantation and who had rejection despite receiving conventional immunosuppressive treatment. Liver Transplantation Program was initiated at Hospital Israelita Albert Einstein in 1990 and so far over 1,400 transplants have been done. In 2013, 102 deceased donors liver transplantations were performed. The main indications for transplantation were hepatocellular carcinoma (38%), hepatitis C virus (33.3%) and alcohol liver cirrhosis (19.6%). Of these, 36% of patients who underwent transplantation showed biological MELD score > 30. Patient and graft survival in the first year was, 82.4% and 74.8%, respectively. A major challenge in liver transplantation field is the insufficient number of donors compared with the growing demand of transplant candidates. Thus, we emphasize that appropriated donor/receptor selection, allocation and organ preservation topics should contribute to improve the number and outcomes in liver transplantation. PMID:25993082

The purpose of this study is to analyze the donor and tissue profile of a community eye bank in Eastern India. Eye bank records were analyzed for the period July 2007-June 2011. Variables analyzed included donor demographics (age, gender, and ethnicity), donor cause of death, consent for recovery, death-to-preservation interval, preservation-to-utilization interval, endothelial cell density (ECD), corneal suitability for transplantation, and corneal tissue utilization. During this study period, 743 corneal tissues were retrieved from 373 donors (male:female = 263:110). The mean age of donors was 52 ± 21 years (range: 3-95 years). The most common donor age group was 41-50 and 71-80 years. Most of the donors belonged to one religious faith (99%). The most common causes of death were cardiorespiratory failure (34%) followed by road traffic accident (30%). Majority donors were motivated (n = 320; 86%), and remaining (n = 53; 14%) were voluntary. Most of the consents were given by sons or daughters of the deceased (45%) followed by siblings (18%). Mean death-to-preservation interval was 3.9 ± 1.9 h. Mean preservation-to-utilization interval was 56.0 ± 24.4 h. The mean ECD of donor corneal tissue was 2857 ± 551 cells/mm 2 and the median value was 2898 cells/mm 2 . Of harvested corneas 556 (75%) corneal tissues were utilized. The most common causes of nonutilization were septicemia in donor (n = 56; 30%) and poor quality of tissue (n = 55; 30%). Although, there is significant corneal tissue utilization, there is a need for increased awareness among people in order to augment voluntary donations.

Educators routinely use standardized patients to teach medical students a variety of clinical concepts. Standardized patients have also been used to teach students about medical ethics and deceased organ donation. Not reported before, however, is the use of standardized patients to educate medical students about the ethical issues in living organ donation. It seems important to fill this gap because in the United States, roughly 45% of organ donors are living donors, and these patients will visit physicians throughout their lifespan, not just with the occurrence of donation. This article reports an experience teaching concepts in living donation and transplant ethics to second-year osteopathic medicine students using a standardized patient and supplementary instructional materials (eg, film, panel discussion, reading list). Specifically, a transplant ethics module was created that included an actor portraying a living donor candidate who had a number of case variables pertaining to medical and psychosocial matters. Instructional themes included informed consent, altruism, patient selection criteria, organ vending, and post-donation support systems.

We report a case of lethal hepatorenal insufficiency in a 52-year-old man who received successful simultaneous hepatorenal transplantation from a deceased donor. The patient had undergone live-donor liver transplantation for type-C hepatitis and liver cirrhosis 11 years before he developed graft liver dysfunction due to recurrent viral hepatitis and cirrhosis. At that instance, he also developed end-stage renal dysfunction due to calcineurin inhibitor nephropathy and hepatorenal syndrome. Although he needed three open hemostases and abundant blood transfusion, he was withdrawn from continuous hemodiafiltration on the 55th day and discharged from the hospital on the 272nd day postoperatively. Simultaneous hepatorenal transplantation was reported to be associated with more favorable outcomes of graft function, lower rejection rates, but higher perioperative complication rates compared with liver transplantation alone in patients on hemodialysis. Particularly, close attention should be paid for hemostasis since patients have a hemorrhagic tendency until the recovery of graft liver function.

Liver transplantation remains the treatment of choice for patients with end-stage liver disease. However, allograft availability continues to be a problem, and extending the criteria for organ acceptance is key. Deceased donors after electrical accidents, as well as electricity-traumatized allografts, are not common but should be considered suitable. This study describes 2 cases of heart-beating organ donors with electrical injury to the liver. In 1 case, the electric shock was the cause of death; in the second case, the injury was caused by defibrillation at organ procurement. Both allografts had sustained sizeable electrical injury, and both resulted in excellent early posttransplant outcomes. These cases demonstrate that electrocution is not a contraindication to donation and that electricity-traumatized allografts may remain transplantable after careful assessment. Education of all staff in the management of such donors can optimize utility of such allografts. Copyright © 2016 Elsevier Inc. All rights reserved.

Intensive care medicine and organ donation: exploring the last frontiers?

Escudero, D; Otero, J

The main, universal problem for transplantation is organ scarcity. The gap between offer and demand grows wider every year and causes many patients in waiting list to die. In Spain, 90% of transplants are done with organs taken from patients deceased in brain death but this has a limited potential. In order to diminish organ shortage, alternative strategies such as donations from living donors, expanded criteria donors or donation after circulatory death, have been developed. Nevertheless, these types of donors also have their limitations and so are not able to satisfy current organ demand. It is necessary to reduce family denial and to raise donation in brain death thus generalizing, among other strategies, non-therapeutic elective ventilation. As intensive care doctors, cornerstone to the national donation programme, we must consolidate our commitment with society and organ transplantation. We must contribute with the values proper to our specialization and try to reach self-sufficiency by rising organ obtainment. Copyright © 2015 Elsevier España, S.L.U. and SEMICYUC.

As the organ shortage continues to grow, the creation of social media communities by transplant hospitals and the public is rapidly expanding to increase the number of living donors. Social media communities are arranged in myriad ways and without standardization, raising concerns about transplant candidates' and potential donors' autonomy and quality of care. Social media communities magnify and modify extant ethical issues in deceased and living donation related to privacy, confidentiality, professionalism, and informed consent, and increase the potential for undue influence and coercion for potential donors and transplant candidates. Currently, no national ethical guidelines have been developed in the United States regarding the use of social media to foster organ transplantation. We provide an ethical framework to guide transplant stakeholders in using social media for public and patient communication about transplantation and living donation, and offer recommendations for transplant clinical practice and future research. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

To maximize deceased donation, it is necessary to facilitate organ recovery from expanded criteria donors (ECDs). Utilization of donors meeting the kidney definition for ECDs increases access to kidney transplantation and reduces waiting times; however, ECDs often do not proceed to kidney recovery. Based on a prospective study of three Organ Procurement Organizations in the United States, we describe the characteristics of donors meeting the Organ Procurement and Transplant Network (OPTN) ECD kidney definition (donor age 60+ or donor age 50-60 years with two of the following: final serum creatinine > 1.5 mg/dL, history of hypertension, or death from cerebral vascular accident) who donated a liver without kidney recovery. ECDs with organs recovered between February 2003 and September 2005 by New England Organ Bank, Gift of Life Michigan, and LifeChoice Donor Services were studied (n = 324). All donors were declared dead by neurological criteria. Data on a wide range of donor characteristics were collected, including donor demographics, medical history, cause of death, donor status during hospitalization, serological status, and donor kidney quality. Logistic regression models were used to identify donor characteristics predictive of liver-alone donation. Seventy-four of the 324 donors fulfilling the ECD definition for kidneys donated a liver alone (23%). History of diabetes, final serum creatinine > 1.5 mg/dL, age 70+, and presence of proteinuria were associated with liver-alone donation in univariate models. On multivariate analysis, only final serum creatinine > 1.5 mg/dL and age 70+ were independently predictive of liver donation alone. Older age and elevated serum creatinine may be perceived as stronger contraindications to kidney donation than the remaining elements of the ECD definition. It is likely that at least a proportion of these liver-alone donors represent missed opportunities for kidney transplantation. Copyright © 2012 Elsevier Inc. All rights reserved.

Aspects of deceased organ donation in paediatrics.

PubMed

Brierley, J; Hasan, A

2012-01-01

Organ transplantation offers children in acute or chronic severe organ failure similar opportunities to adults. However, while the number who might benefit is relatively low, significantly fewer cadaveric donors exist for any given child compared with an adult. Incompatible organ size and relatively low donation rates mean that despite living parental donation and innovations to reduce donated organ size, children die before organs become available. The severity of the UK situation is compounded by restrictions on paediatric living donation, uncertainties over the application of brain death criteria, and ethical concerns about the use of donation after circulatory death. The UK Department of Health's Organ Donation Task Force suggested the means by which the adult donor pool might be increased, recommending that outstanding ethical and legal issues be resolved, but made no specific recommendations about children.

The Spanish model of organ and tissue donation enjoys great prestige in the world medical sphere and has been the object of study and imitation in different countries. Part of this success is due to the fact that since the year 1979 different legal norms have been enacted that have regulated and facilitated donation. The current legislation on the donation and transplant of organs and tissues is based on the principles of the gratuity and confidentiality of the donation, indicating the need for facilitating the formation of organisations at the level of the autonomous communities and at the national level. It also contains the requisites for donation of both live donors and deceased donors, establishing the norms for certification of death due to cardiorespiratory arrest and due to the irreversible cease of brain functions.

Faced with a shortage of organs for liver transplantation, the use of grafts from older donors is justified. However, there remains little consensus on how this use impacts the graft and patient outcomes after transplantation from these older donors. The aim of the present analysis was to assess the graft and patient outcomes after liver transplantation from deceased donors >60 years of age. From January 2007 to January 2011, 505 subjects were identified as liver graft donors after brain death, of which 7.35% were ≥60. To determine the effect of donor age on graft and patient outcomes, we analyzed donor age, recipient age, the Model for End-State Liver Disease (MELD) score of recipients at the time of transplantation, early posttransplant complications, and mortality. The posttransplant follow-up was 29 ± 25.5 months, and 3-year patient mortality from donors, grouped according to age, was 7.92% with donors <30; 15.78% with donors 30-50, 10.68% with donors 50-60, and 12.50% with donors >60. After analysis of patient and graft survival based on donor graft age, 3-year patient survival according donor age was 89.29% with donors <30, 83.85% with donors 30-50, 89.89% with donors 50-60, and 87.50% with donors >60. Analysis showed overall patient and graft survival rates from older donors were not worse than those from younger donors (P > .1). Among the cases, 3-year patient survival according to MELD score was 91.19% with a MELD of I, 85.37% with a MELD of II, and 67.67% with a MELD of III; differences in graft and patient survival when comparing low MELD I and high MELD III were significantly different (P < .01). A more advanced age of a donor should not be a contraindication for liver transplantation. The present analysis shows that liver grafts from donors >60 can be used safely in older recipients who presented with relatively low MELD scores. Analyses also indicate that high MELD obtained before transplantation may be an important prognostic factor for graft and patient survival.

Confidentiality of personal identifiers potentially linking the genetic results from biobanking participants back to the donor and donor relatives is a concern. The risks associated with a breach of confidentiality should be ascertained when biobanks collect samples requiring the consent of a family decision maker (FDM) from deceased organ and tissue donors. This article explores FDM knowledge and opinions regarding risks associated with participation in biobanking research in the context of the Genotype-Tissue Expression (GTEx) Project. Data collection included a survey completed by organ procurement organization requesters (n = 37) and semistructured telephone interviews with the FDMs (n = 85). Donor families were more likely to know that there was a risk that a patient's identity could be revealed through a breach of confidentiality (p < 0.05). They also were more likely to understand that researchers using biobanked tissue would not have access to the patient's exact identity (p < 0.05). FDMs who refused donation were more concerned about risks than donors and reported lower levels of support for medical research in general. Finally, families were frequently interested in the return of results and willing to trade absolute confidentiality for participation. Clear discussion of the risk of breach of confidentiality is needed during the consent process. The risk and benefit equation could be equalized if studies such as GTEx offered genomic results to interested participants.

Lymphocyte-depleting induction lowers acute rejection (AR) rates among high-immunologic risk (HIR) renal transplant recipients, including African Americans (AAs), retransplants, and the sensitized. It is unclear whether different HIR subgroups experience similarly low rates of AR. We aimed to describe the incidence of AR and de novo donor-specific antibody (dnDSA) among HIR recipients categorized by age, race, or donor type. All received antithymocyte globulin (ATG) induction and triple maintenance immunosuppression. A total of 464 HIR recipients from 2007 to 2014 were reviewed. AR and dnDSA rates at 1 year for the entire population were 14% and 27%, respectively. AR ranged from 6.7% among living donor (LD) recipients to 30% in younger AA deceased donor (DD) recipients. De novo donor-specific antibody at 1 year ranged from 7% in older non-AA LD recipients to 32% in AAs. AA race remained as an independent risk factor for AR among DD recipients and for dnDSA among all HIR recipients. Development of both AR and dnDSA within the first year was associated with a 54% graft survival at 5 years and was an independent risk factor for graft loss. Despite utilization of recommended immunosuppression for HIR recipients, substantial disparities exist among subgroups, warranting further consideration of individualized immunosuppression in certain HIR subgroups. © 2016 Steunstichting ESOT.

This 5 year observational multicentre study conducted in the Nord Italian Transplant programme area evaluated outcomes in patients receiving kidneys from donors over 60 years allocated according to a combined clinical and histological algorithm. Low-risk donors 60-69 years without risk factors were allocated to single kidney transplant (LR-SKT) based on clinical criteria. Biopsy was performed in donors over 70 years or 60-69 years with risk factors, allocated to Single (HR-SKT) or Dual kidney transplant (HR-DKT) according to the severity of histological damage. Forty HR-DKTs, 41 HR-SKTs and 234 LR-SKTs were evaluated. Baseline differences generally reflected stratification and allocation criteria. Patient and graft (death censored) survival were 90% and 92% for HR-DKT, 85% and 89% for HR-SKT, 88% and 87% for LR-SKT. The algorithm appeared user-friendly in daily practice and was safe and efficient, as demonstrated by satisfactory outcomes in all groups at 5 years. Clinical criteria performed well in low-risk donors. The excellent outcomes observed in DKTs call for fine-tuning of cut-off scores for allocation to DKT or SKT in high-risk patients. © 2013 Steunstichting ESOT. Published by John Wiley & Sons Ltd.

The sequelae of cardiac arrest (CA) and cardiopulmonary resuscitation (CPR) in organ donors potentially results in ischemic organ injury and graft dysfunction after transplantation. Thresholds of resuscitation times in brain dead liver donors have not been established so far. We report the case of a brain dead liver donor who experienced 2.5 hours of CPR whose liver was successfully transplanted. A 75-year-old male experienced CA and was treated by CPR with streptokinase application for 2.5 hours until stabilization of cardiac function. Brain death was diagnosed at the day of admission and organ donation carried out within 24 hours. The DRI was 2.2 with a CIT of 8.8 hours. The liver was transplanted into a 64-year-old recipient suffering from alcoholic liver cirrhosis and a MELD-score of 10 non representative for severity of disease. During follow up of 4 years ERCP and stenting was performed regularly for biliary anastomosis stenosis. The patient remained in a very good overall state of health without any signs of liver dysfunction. This case demonstrates that an extensive period of CPR is not an obligatory exclusion criterion for liver donation. Thresholds of CPR times as well as predictive factors in donors with CA should be established. Celsius.

The introduction of the Mayo End-Stage Liver Disease score into the Organ Procurement and Transplantation Network (OPTN) deceased donor liver allocation policy in 2002 has led to a significant increase in the number of simultaneous liver-kidney transplants in the United States. Despite multiple attempts, clinical science has not been able to reliably predict which liver candidates with renal insufficiency will recover renal function or need a concurrent kidney transplant. The problem facing the transplant community is that currently there are almost no medical criteria for candidacy for simultaneous liver-kidney allocation in the United States, and this lack of standardized rules and medical eligibility criteria for kidney allocation with a liver is counter to OPTN's Final Rule. Moreover, almost 50% of simultaneous liver-kidney organs come from a donor with a kidney donor profile index of ≤0.35. The kidneys from these donors could otherwise be allocated to pediatric recipients, young adults or prior organ donors. This paper presents the new OPTN and United Network of Organ Sharing simultaneous liver-kidney allocation policy, provides the supporting evidence and explains the rationale on which the policy was based. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Donated tissues can save lives of critically burned patients and those needing a heart valve replacement. Tissues enhance the lives of a million recipients annually through transplants of corneas, bones, tendons, and vein grafts. Unfortunately, the need for some tissues exceeds their availability. The goal of the quantitative component of this mixed methods study was to identify the grief, posttraumatic stress, personal growth, and ongoing attachment response of tissue donors' family members during a 2-year period. Simultaneous mixed methods design. The sample for this study consisted of 52 tissue donors' family members, mostly widows (83%). Data were collected for 2 years to test changes in grief, posttraumatic stress, panic behavior, personal growth, and ongoing attachment. The bereaved participants experienced significantly fewer grief reactions, less posttraumatic stress, and greater personal growth. There was no significant difference in the ongoing attachment to their deceased loved ones. The results of this study may reinforce the positive meaning that tissue donors' family members can find in tissue donation. Findings also demonstrate that the bereavement process corroborates contemporary bereavement and attachment theories. Health professionals are encouraged to seek donations with less worry that tissue donors' family members will experience adverse outcomes during bereavement.

Acute rejection is detrimental to most transplanted solid organs, but is considered to be less of a consequence for transplanted livers. We evaluated risk factors for and outcomes after biopsy-proven acute rejection (BPAR) based on an analysis of a more recent national sample of recipients of liver transplants from living and deceased donors. We analyzed data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) from 2003 through 2014 as the exploratory cohort and the Scientific Registry of Transplant Recipients (SRTR) from 2005 through 2013 as the validation cohort. We examined factors associated with time to first BPAR using multivariable Cox regression or discrete-survival analysis. Competing risks methods were used to compare causes of death and graft failure between recipients of living and deceased donors. At least 1 BPAR episode occurred in 239 of 890 recipients in A2ALL (26.9%) and 7066 of 45,423 recipients in SRTR (15.6%). In each database, risk of rejection was significantly lower when livers came from biologically related living donors (A2ALL hazard ratio [HR], 0.57; 95% confidence interval [CI], 0.43-0.76; and SRTR HR, 0.78; 95% CI, 0.66-0.91) and higher in liver transplant recipients with primary biliary cirrhosis, of younger age, or with hepatitis C. In each database, BPAR was associated with significantly higher risks of graft failure and death. The risks were highest in the 12 month post-BPAR period in patients whose first episode occurred more than 1 year after liver transplantation: HRs for graft failure were 6.79 in A2ALL (95% CI, 2.64-17.45) and 4.41 in SRTR (95% CI, 3.71-5.23); HRs for death were 8.81 in A2ALL (95% CI, 3.37-23.04) and 3.94 in SRTR (95% CI, 3.22-4.83). In analyses of cause-specific mortality, associations were observed for liver-related (graft failure) causes of death but not for other causes. Contrary to previous data, acute rejection after liver transplant is associated with significantly increased risk of graft failure, all-cause mortality, and graft failure-related death, regardless of primary liver disease etiology. Living donor liver transplantation from a biologically related donor is associated with decreased risk of rejection. Copyright © 2017 AGA Institute. Published by Elsevier Inc. All rights reserved.

Results of donation after circulatory death (DCD) liver transplantation are impaired by graft loss, resulting mainly from non-anastomotic biliary stricture. Donor age is a risk factor in deceased donor liver transplantation, and particularly in DCD liver transplantation. At the authors' institute, age is not an absolute exclusion criterion for discarding DCD liver grafts, DCD donors receive comfort therapy before withdrawal, and cold ischaemia is minimized. All consecutive DCD liver transplantations performed from 2003 to 2012 were studied retrospectively. Three age groups were compared in terms of donor and recipient demographics, procurement and transplantation conditions, peak laboratory values during the first post-transplant 72 h, and results at 1 and 3 years. A total of 70 DCD liver transplants were performed, including 32 liver grafts from donors aged 55 years or less, 20 aged 56-69 years, and 18 aged 70 years or more. The overall graft survival rate at 1 month, 1 and 3 years was 99, 91 and 72 per cent respectively, with no graft lost secondary to non-anastomotic stricture. No difference other than age was noted between the three groups for donor or recipient characteristics, or procurement conditions. No primary non-function occurred, but one patient needed retransplantation for artery thrombosis. Biliary complications were similar in the three groups. Graft and patient survival rates were no different at 1 and 3 years between the three groups (P = 0.605). Results for DCD liver transplantation from younger and older donors were similar. Donor age above 50 years should not be a contraindication to DCD liver transplantation if other donor risk factors (such as warm and cold ischaemia time) are minimized. © 2014 BJS Society Ltd.

Given the shortage of kidneys for transplant, living kidney donation (LKD) is increasingly used to expand the organ donor pool. Although Hispanics/Latinos need disproportionately more kidney transplants, they receive a smaller proportion of living donor kidney transplants than other ethnic/racial groups. To assess Hispanics' awareness, perceptions, misconceptions, cultural beliefs, and values about and barriers to LKD. Nine focus groups were conducted with 76 adult Hispanics in Chicago, Illinois, between January and March 2012. Focus groups included kidney transplant recipients, living kidney donors, dialysis patients, and the general Hispanic public. Several themes emerged as perceived barriers to LKD. Many participants identified knowledge deficits about LKD, expressing uncertainty about the differences between LKD and deceased donation, and whether kidney disease simultaneously afflicts both kidneys. Many believed that donors experience dramatically shorter life expectancies, are unable to have children, and are more susceptible to kidney disease after donating. Recipients and donors reported that family members were involved in discussions about the donor's decision to donate, with some family members discouraging donation. Financial barriers cited included fear of becoming unable to work, losing one's job, or being unable to pay household bills while recovering. Participants also identified logistic barriers for undocumented immigrants (eg, the inability to obtain government insurance for transplant candidates and uncertainty about their eligibility to donate). Donors desired information about optimizing self-care to promote their remaining kidney's health. Culturally competent interventions are needed to redress Hispanics' knowledge deficits and misconceptions and reduce LKD disparities among Hispanics.

The broader use of combined expanded criteria donor and donation after circulatory death (ECD/DCD) kidneys may help expand the deceased donor pool. The purpose of our study was to evaluate discard rates of kidneys from ECD/DCD donors and factors associated with discard. ECD/DCD donors and kidneys were evaluated from January 1, 2000 to March 31, 2011 using data from the Scientific Registry of Transplant Recipients. The kidney donor risk index was calculated for all ECD/DCD kidneys. Multivariable logistic regression models were used to determine risk factors for discarding both donor kidneys. The Kaplan-Meier product limit method and the log-rank statistic were used to assess the cumulative probability of graft failure for transplants from ECD/DCD donors where the mate kidney was discarded versus both kidneys were used. There were 896 ECD/DCD donors comprising 1792 kidneys. Both kidneys were discarded in 44.5% of donors, whereas 51.0% of all available kidneys were discarded. The kidney donor risk index scores were higher among donors of discarded versus transplanted kidneys (median, 1.82; interquartile range, 1.60, 2.07 versus median, 1.67; interquartile range, 1.49, 1.87, respectively; P<0.001); however, the distributions showed considerable overlap. The adjusted odds ratios for discard were higher among donors who were older, diabetic, AB blood type, and hepatitis C positive. The cumulative probabilities of total graft failure at 1, 3, and 5 years were 17.3%, 36.5%, and 55.4% versus 13.8%, 24.7%, and 40.5% among kidneys from donors where only one versus both kidneys were transplanted, respectively (log rank P=0.04). Our study shows a significantly higher discard rate for ECD/DCD kidneys versus prior reports. Some discarded ECD/DCD kidneys may be acceptable for transplantation. Additional studies are needed to evaluate the factors that influence decision making around the use of ECD/DCD kidneys. Copyright © 2016 by the American Society of Nephrology.

Results There were 896 ECD/DCD donors comprising 1792 kidneys. Both kidneys were discarded in 44.5% of donors, whereas 51.0% of all available kidneys were discarded. The kidney donor risk index scores were higher among donors of discarded versus transplanted kidneys (median, 1.82; interquartile range, 1.60, 2.07 versus median, 1.67; interquartile range, 1.49, 1.87, respectively; P<0.001); however, the distributions showed considerable overlap. The adjusted odds ratios for discard were higher among donors who were older, diabetic, AB blood type, and hepatitis C positive. The cumulative probabilities of total graft failure at 1, 3, and 5 years were 17.3%, 36.5%, and 55.4% versus 13.8%, 24.7%, and 40.5% among kidneys from donors where only one versus both kidneys were transplanted, respectively (log rank P=0.04). Conclusions Our study shows a significantly higher discard rate for ECD/DCD kidneys versus prior reports. Some discarded ECD/DCD kidneys may be acceptable for transplantation. Additional studies are needed to evaluate the factors that influence decision making around the use of ECD/DCD kidneys. PMID:26668028

This study aimed to estimate the numbers of foreign patients seeking organ transplantation (OT) in Korea and to examine the relationship between the trend of deceased donors in Korea and number of Korean patients seeking OT overseas since 2000. Data on foreigners who received a transplant in Korea were obtained from the Korean Network for Organ Sharing. Data on overseas transplants were obtained from 42 transplant centers surveyed through transplant coordinators. A total of 336 foreigners underwent OT (kidney transplantation [KT], 174; liver transplantation [LT], 162) in Korea between 2006 and 2016. The Mongolians were the most common foreigners who undergo KTs (32%), followed by the Chinese (18%), Americans (9%), and Emiratis (7%). Among foreigners undergoing LTs, the most common country of origin was Mongolia (39%), followed by United Arab Emirates (23%), China (13%), and the United States (6%). A total of 2206 Korean patients underwent overseas OT (KT, 977; LT, 1229) between 2000 and 2016. In 97% of overseas KT cases (n = 942) and 98% (n = 1205) of overseas LT cases, the transplantations were performed in China. The relationship between the number of deceased donors in Korea and the number of overseas transplants after 2006 indicates a highly negative correlation. (ρ = -0.988, P < 0.001). This analysis of trends in Korean patients seeking OT overseas demonstrates the importance of multilateral approaches to address organ trafficking. National effort to achieve self-sufficiency by increasing activities for organ donations is one of the fundamental solutions to transplant tourism.

The logistics of deceased-donor renal transplants are largely affected by cold ischemia time. However, to attain successful outcomes, other issues must be considered. Extending cold ischemia time to accommodate these issues would be valuable. We investigated the role of hypothermic machine perfusion to extend cold ischaemia time. Deceased-donor kidneys were allocated to a storage method, depending on predicted time to operation. Kidneys to be transplanted from 8:00 AM to 8:00 PM in the transplant room remained in static cold storage. If predicted operating time was out of hours, the kidney was transferred to hypothermic machine perfusion and transplanted at the earliest opportunity on the dedicated transplant list. There were 74 kidneys transplanted from hypothermic machine perfusion and 101 kidneys from static cold storage. Median cold ischemia time was 23.85 hours in the hypothermic machine perfusion group, compared with 13 hours in the static cold storage group (P ≤ .0001). There were 20 kidneys (27%) from hypothermic machine perfusion that had delayed graft function, compared with 47 kidneys (47%) in the static cold storage group (P = .012). There were no other significant differences in graft or postoperative complications. This study demonstrated that improved early graft outcomes can be achieved following longer cold ischemia time by using hypothermic machine perfusion rather than static cold storage. This effect is likely multifactorial including the inherent effects of hypothermic machine perfusion, improved recipient preparation, and possibly better perioperative conditions.

Deciding about the organ donation of one's brain-dead beloved often occurs in an unexpected and delicate situation. We explored the decision making of the relatives of potential brain-dead donors, its evaluation, and the factors influencing decision making. We used the integrative review method. Our search included 10 databases. Inclusion criteria were presence of the donation request or the subsequent decision process. Three authors independently assessed the eligibility of identified articles. Content analysis of 70 included articles led to three themes: decision, evaluation, and support. We extracted results and recommendations concerning these three themes. The timing of the request and understandable information influence the decision. The relatives evaluate their decision differently: in case of refusal, approximately one third regret their decision, and in case of consent, approximately one tenth mention regret. The relatives are often ambivalent about their values (protection, altruism, and respect) and the deceased's wishes, not wanting additional suffering either for their beloved or for themselves. Support is mainly focused on increasing consent rates and less on satisfaction with the decision. Evaluation of decision making by the relatives of potential brain-dead donors reveals possibilities for improving the decision process. Special skills of the requester, attention to the circumstances, and unconditional support for the relatives might prevent the relatives' regret about refusal and unnecessary loss of organs. We hypothesize that support in exploring the relatives' values and the deceased's wishes can lead to stable decisions. This hypothesis deserves further investigation.
