Children who receive a non‐renal solid organ transplant may develop secondary renal failure requiring kidney transplantation. We investigated outcomes of 165 pediatric kidney transplant recipients who previously received a heart, lung, or liver transplant using data from 1988 to 2012 reported to the United Network for Organ Sharing. Patient and allograft survival were compared with 330 matched primary kidney transplant (PKT) recipients. Kidney transplantation after solid organ transplant (KASOT) recipients experienced similar allograft survival: 5‐ and 10‐year graft survival was 78% and 60% in KASOT recipients, compared to 80% and 61% in PKT recipients (p = 0.69). However, KASOT recipients demonstrated worse 10‐year patient survival (75% KASOT vs. 97% PKT, p < 0.001). Competing risks analysis indicated that KASOT recipients more often experienced graft loss due to patient death (p < 0.001), whereas allograft failure per se was more common in PKT recipients (p = 0.01). To study more recent outcomes, kidney transplants performed from 2006 to 2012 were separately investigated. Since 2006, KASOT and PKT recipients had similar 5‐year graft survival (82% KASOT vs. 83% PKT, p = 0.48), although 5‐year patient survival of KASOT recipients remained inferior (90% KASOT vs. 98% PKT, p < 0.001). We conclude that despite decreased patient survival, kidney allograft outcomes in pediatric KASOT recipients are comparable to those of PKT recipients.  相似文献

The infrequent use of ABO‐incompatible (ABOi) kidney transplantation in the United States may reflect concern about the costs of necessary preconditioning and posttransplant care. Medicare data for 26 500 live donor kidney transplant recipients (2000 to March 2011), including 271 ABOi and 62 A2‐incompatible (A2i) recipients, were analyzed to assess the impact of pretransplant, transplant episode and 3‐year posttransplant costs. The marginal costs of ABOi and A2i versus ABO‐compatible (ABOc) transplants were quantified by multivariate linear regression including adjustment for recipient, donor and transplant factors. Compared with ABOc transplantation, patient survival (93.2% vs. 88.15%, p = 0.0009) and death‐censored graft survival (85.4% vs. 76.1%, p < 0.05) at 3 years were lower after ABOi transplant. The average overall cost of the transplant episode was significantly higher for ABOi ($65 080) compared with A2i ($36 752) and ABOc ($32 039) transplantation (p < 0.001), excluding organ acquisition. ABOi transplant was associated with high adjusted posttransplant spending (marginal costs compared to ABOc ‐ year 1: $25 044; year 2: $10 496; year 3: $7307; p < 0.01). ABOi transplantation provides a clinically effective method to expand access to transplantation. Although more expensive, the modest increases in total spending are easily justified by avoiding long‐term dialysis and its associated morbidity and cost.  相似文献

The COVID-19 pandemic has significantly changed the landscape of kidney transplantation in the United States and worldwide. In addition to adversely impacting allograft and patient survival in postkidney transplant recipients, the current pandemic has affected all aspects of transplant care, including transplant referrals and listing, organ donation rates, organ procurement and shipping, and waitlist mortality. Critical decisions were made during this period by transplant centers and individual transplant physicians taking into consideration patient safety and resource utilization. As countries have begun administering the COVID vaccines, new and important considerations pertinent to our transplant population have arisen. This comprehensive review focuses on the impact of COVID-19 on kidney transplantation rates, mortality, policy decisions, and the clinical management of transplanted patients infected with COVID-19.  相似文献

Abstract: Background:  The acceptance and application of the concept that brain death is a valid determination of death is the central issue in organ donation. However, whether attitude to brain death of health care professionals influences the organ procurement process has not been systematically studied.
Methods:  Questionnaires were distributed to health care professionals involved in the organ procurement process (intensive care, internal medicine, emergency room, anesthesia) in all hospitals in Israel. Attitude to brain death (defined as positive if the respondent accepted brain death as a valid determination of death, negative or do not know) and level of comfort in performing key donor-related tasks were analyzed.
Results:  A total of 2366 completed questionnaires were returned (629 doctors and 1737 nurses; response rate 60.3%). Overall, 78.9% of respondents had a positive attitude to brain death. This was significantly associated with increasing age, higher professional status and was most prevalent amongst intensive care unit staff (p < 0.001 for all variables). These respondents felt significantly more comfortable informing the transplant coordinator of a potential donor, explaining brain death to the family, raising the subject of organ donation, approaching the family about donation and providing support to the grieving family. In addition, they believed the transplant coordinator should be involved early in the donation process.
Conclusions:  The understanding and acceptance of brain death as a valid determination of death was associated with a positive effect on the level of comfort of health care professionals in performing key donor-related tasks. Reinforcing a positive attitude to brain death among health care professionals may facilitate the procurement process.  相似文献

Clinicians and other health care professionals involved in the evaluation and management of organ transplant recipients and organ donors quite commonly encounter ethically complex scenarios during the course of their work. The response to such challenging situations may be influenced by personal experiences and beliefs, programmatic or institutional policy, existing legislation, published literature, and consultative analysis by experts in the field of biomedical ethics. As organ transplantation continues to evolve in its scope, complexity, and global reach, there is a growing need for transplant programs to carefully discuss and reach consensus on how to deal with specific ethical issues that may arise. In this article, we present the summaries of 3 clinically relevant case scenarios from the 2007 Mayo Clinic Course in Transplant Ethics, along with the results of audience responses and discussion facilitated by a volunteer panel of experts from North America.1 The cases provide cogent examples of how open, consensus-driven discussion of specific ethically charged scenarios can be useful in guiding progressive clinical practices in organ transplantation.  相似文献

There are significant risks and inefficiencies associated with organ procurement travel. In an effort to identify, quantify, and define opportunities to mitigate these risks and inefficiencies, 25 experts from the transplantation, transportation and insurance fields were convened. The forum concluded that: on procurement travel practices are inadequate, there is wide variation in the quality of aero‐medical transportation, current travel practices for organ procurement are inefficient and there is a lack of standards for organ procurement travel liability coverage. The forum concluded that the transplant community should require that air‐craft vendors adhere to industry quality standards compatible with the degree of risk in their mission profiles. Within this context, a purchasing collaborative within the transplant community may offer opportunities for improved service and safety with lower costs. In addition, changes in travel practices should be considered with broader sharing of procurement duties across centers. Finally, best practice standards should be instituted for life insurance for transplant personnel and liability insurance for providers. Overall, the aims of these proposals are to raise procurement travel standards and in doing so, to improve the transplantation as a whole.  相似文献

The American Society of Transplant Surgeons (ASTS) sought whether the right number of abdominal organ transplant surgeons are being trained in the United States. Data regarding fellowship training and the ensuing job market were obtained by surveying program directors and fellowship graduates from 2003 to 2005. Sixty‐four ASTS‐approved programs were surveyed, representing 139 fellowship positions in kidney, pancreas and/or liver transplantation. One‐quarter of programs did not fill their positions. Forty‐five fellows graduated annually. Most were male (86%), aged 31–35 years (57%), married (75%) and parents (62%). Upon graduation, 12% did not find transplant jobs (including 8% of Americans/Canadians), 14% did not get jobs for transplanting their preferred organ(s), 11% wished they focused more on transplantation and 27% changed jobs early. Half fellows were international medical graduates; 45% found US/Canadian transplant jobs, particularly 73% with US/Canadian residency training. Fellows reported adequate exposure to training volume, candidate selection, pre/postoperative care and organ procurement, but not to donor management/selection, outpatient care and core didactics. One‐sixth noted insufficient ‘mentoring/preparation for a transplantation career’. Currently, there seem to be enough trainees to fill entry‐level positions. One‐third program directors believe that there are too many trainees, given the current and foreseeable job market. ASTS is assessing the total workforce of transplant surgeons and evolving manpower needs.  相似文献

Selection criteria and benefit of liver transplantation for hepatic metastases from neuroendocrine tumors (NETs) remain uncertain. Eighty‐eight consecutive patients with metastatic NETs eligible for liver transplantation according to Milan‐NET criteria were offered transplant (n = 42) versus nontransplant options (n = 46) depending on list dynamics, patient disposition, and age. Tumor burden between groups did not differ. Transplant patients were younger (40.5 vs. 55.5 years; p < 0.001). Long‐term outcomes were compared after matching between groups made on multiple Cox models adjusted for propensity score built on logistic models. Survival benefit was the difference in mean survival between transplant versus nontransplant options. No patients were lost or died without recurrence. Median follow‐up was 122 months. The transplant group showed a significant advantage over nontransplant strategies at 5 and 10 years in survival (97.2% and 88.8% vs. 50.9% and 22.4%, respectively; p < 0.001) and time‐to‐progression (13.1% and 13.1% vs. 83.5% and 89%; p < 0.001). After adjustment for propensity score, survival advantage of the transplant group was significant (hazard ratio = 7.4; 95% confidence interval (CI): 2.4–23.0; p = 0.001). Adjusted transplant‐related survival benefit was 6.82 months (95% CI: 1.10–12.54; p = 0.019) and 38.43 months (95% CI: 21.41–55.45; p < 0.001) at 5 and 10 years, respectively. Liver transplantation for metastatic NETs under restrictive criteria provides excellent long‐term outcome. Transplant‐related survival benefit increases over time and maximizes after 10 years.  相似文献

Certain patient groups are predicted to derive significant survival benefit from transplantation with expanded criteria donor (ECD) kidneys. An algorithm published in 2005 by Merion and colleagues characterizes this group: older adults, diabetics and registrants at centers with long waiting times. Our goal was to evaluate ECD listing practice patterns in the United States in terms of these characteristics. We reviewed 142 907 first‐time deceased donor kidney registrants reported to United Network for Organ Sharing (UNOS) between 2003 and 2008. Of registrants predicted to benefit from ECD transplantation according to the Merion algorithm ('ECD‐benefit'), 49.8% were listed for ECD offers ('ECD‐willing'), with proportions ranging from 0% to 100% by transplant center. In contrast, 67.6% of adults over the age of 65 years were ECD‐willing, also ranging from 0% to 100% by center. In multivariate models, neither diabetes nor center waiting time was significantly associated with ECD‐willingness in any subgroup. From the time of initial registration, irrespective of eventual transplantation, ECD‐willingness was associated with a significant adjusted survival advantage in the ECD‐benefit group (HR for death 0.88, p < 0.001) and in older adults (HR 0.89, p < 0.001), but an increased mortality in non‐ECD‐benefit registrants (HR 1.11, p < 0.001). In conclusion, ECD listing practices are widely varied and not consistent with published recommendations, a pattern that may disenfranchise certain transplant registrants.  相似文献

The Israeli transplantation law of 2008 stipulated that organ trading is a criminal offense, and banned the reimbursement of such transplants by insurance companies, thus decreasing dramatically transplant tourism from Israel. We evaluated the law's impact on the number and the socio‐demographic features of 575 consecutive living donors, transplanted in the largest Israeli transplantation center, spanning 5 years prior to 5 years after the law's implementation. Living kidney donations increased from 3.5 ± 1.5 donations per month in the pre‐law period to 6.1 ± 2.4 per month post‐law (p < 0.001). This was mainly due to a rise in intra‐familial donations from 2.1 ± 1.1 per month to 4.6 ± 2.1 per month (p < 0.001). In unrelated donors we found a significant change in their socio‐demographic characteristics: mean age increased from 35.4 ± 7.4 to 39.9 ± 10.2 (p = 0.001), an increase in the proportion of donors with college level or higher education (31.0% to 63.1%; p < 0.001) and donors with white collar occupations (33.3% to 48.3%, p = 0.023). In conclusion, the Israeli legislation that prohibited transplant tourism and organ trading in accordance with Istanbul Declaration, was associated with an increase in local transplantation activity, mainly from related living kidney donors, and a change in the profile of unrelated donors into an older, higher educated, white collar population.  相似文献

Lung procurement is increasing during multiorgan recovery and substantially alters the explant process. This study evaluated whether lung donation by a heart donor affects survival in heart transplant recipients. Retrospective analysis of United Network for Organ Sharing (UNOS) adult heart transplantation data from 1998 to 2012 was performed. Lung donors (LDs) were defined as those having at least one lung procured and transplanted. Non‐LDs had neither lung transplanted. Heart transplant recipients who had previous transplants, who had heterotopic transplants, who were waitlisted for other organs or who were temporarily delisted were excluded from the analysis. Kaplan–Meier survival analysis and Cox proportional hazards regression were performed. Of 23 590 heart transplant recipients meeting criteria during the study period, 8638 (36.6%) transplants were from LDs. Donors in the LD group had less history of cigarette use (15.5% vs. 29.5%, p < 0.001). On univariate analysis, LDs were associated with improved patient survival (p < 0.001). On multivariate analysis, LDs were not significantly associated with patient survival (adjusted hazard ratio 0.98, 95% confidence interval 0.94–1.03). Analysis of the UNOS registry suggested that donor pulmonary status and lung procurement had no detrimental effect on survival in heart transplant recipients, supporting the present practice of using donor lungs whenever possible.  相似文献

Our objective was to evaluate the impact of hydroxyethyl starch (HES) use in organ donors after neurologic determination of death (DNDD) on recipient renal graft outcomes. The following data elements were prospectively collected for every DNDD managed by a single organ procurement organization from June 2011 to July 2013: demographics; critical care endpoints; treatments, including the use of HES; graft cold ischemia time (CIT); and the occurrence of recipient delayed graft function (DGF, dialysis in the first week after transplantation). Logistic regression was performed to identify independent predictors of DGF with a p‐value <0.05. The results were then adjusted for each donor's calculated propensity to receive HES. Nine hundred eighty‐six kidneys were transplanted from 529 donors. Forty‐two percent received HES (1217 ± 528 mL) and 35% developed DGF. Kidneys from DNDDs who received HES had a higher crude rate of DGF (41% vs. 31%, p < 0.001). After accounting for the propensity to receive HES, independent predictors of DGF were age (OR 1.02 [1.01–1.04] per year), CIT (OR 1.04[1.02–1.06] per hour), creatinine (OR 1.5 [1.32–1.72] per mg/dL) and HES use (OR 1.41 [1.02–1.95]). HES use during donor management was independently associated with a 41% increase in the risk of DGF in kidney transplant recipients.  相似文献

We used the United Network for Organ Sharing Database to determine the influence of antibody‐based induction therapy on patient and graft survival in orthotopic liver transplant (OLT) recipients with and without hepatitis C (HCV). We identified all initial OLT patients with HCV serology. Patients were divided into four groups: HCV positive without induction (17 362), HCV positive with induction (3479), HCV negative without induction (20 417) and HCV negative with induction (4357). Both HCV positive and negative patients who received induction did better than those who did not. For HCV positive patients, 5‐year patient survival was 70.8% versus 68.7% (p = 0.004) and graft survival was 65.2% versus 62.1% (p < 0.001). For HCV negative patients, 5‐year patient survival was 78.8% versus 76.7% (p < 0.001) and graft survival was 74.0% versus 70.8% (p < 0.001). On multivariate analysis, induction was associated with improved patient (HR = 0.91: p = 0.024) and graft (HR = 0.88: p < 0.001) survival in HCV positive patients and improved patient (HR = 0.87: p = 0.003) and graft survival (HR = 0.87: p < 0.001) in HCV negative patients. The benefit of induction occurred early and largely dissipated when patients with death within a year were censored. The benefit of induction therapy appeared most pronounced in patients with renal insufficiency or on organ‐perfusion support at transplant.  相似文献

Concern exists about accepting live kidney donation from ‘medically complex donors’—those with risk factors for future kidney disease. This study's aim was to examine variation in complex kidney donor use across US transplant centers. We conducted a retrospective cohort study of live kidney donors using organ procurement and transplantation network data. Donors with hypertension, obesity or estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2 were considered medically complex. Among 9319 donors, 2254 (24.2%) were complex: 1194 (12.8%) were obese, 956 (10.3%) hypertensive and 392 (4.2%) had low eGFR. The mean proportion of medically complex donors at a center was 24% (range 0–65%). In multivariate analysis, donor characteristics associated with medical complexity included spousal relationship to the recipient (OR 1.29, CI 1.06–1.56, p < 0.01), low education (OR 1.19, CI 1.04–1.37, p = 0.01), older age (OR 1.01 per year, CI 1.01–1.02, p < 0.01) and non‐US citizenship (OR 0.70, CI 0.51–0.97, p = 0.03). Renal transplant centers with the highest transplant volume (OR 1.26, CI 1.02–1.57, p = 0.03), and with a higher proportion of (living donation)/(all kidney transplants) (OR 1.97, CI 1.23–3.16, p < 0.01) were more likely to use medically complex donors. Though controversial, the use of medically complex donors is widespread and varies widely across centers.  相似文献

Abdominal organ transplantation faces several challenges: burnout, limited pipeline of future surgeons, changes in liver allocation potentially impacting organ procurement travel, and travel safety. The organ procurement center (OPC) model may be one way to mitigate these issues. Liver transplants from 2009 to 2016 were reviewed. There were 755 liver transplants performed with 525 OPC and 230 in‐hospital procurements. The majority of transplants (87.4%) were started during daytime hours (5 am ‐7 pm ). Transplants with any portion occurring after‐hours were more likely to have procurements in‐hospital (P < .001). Daytime cases (n = 400) had more OPC procured livers and hepatitis C recipients and were less likely to have a donation after circulatory death donor (all P < .05). In adjusted analyses, daytime cases were independently associated with extubation in the operating room and less postoperative transfusion. There were no significant differences in short‐ or long‐term postoperative outcomes. For exported livers, 54.3% were procured by a local team, saving 137 flights (151 559 miles). The OPC resulted in optimally timed liver transplants and decreased resource utilization with no negative impact on patient outcomes. It allows for ease in exporting organs procured by local surgeons, and potentially addresses provider burnout, the transplant surgery pipeline, and surgeon travel.  相似文献

Health care professionals and the information that they provide to the public on organ donation and transplantation (ODT) influence attitudes toward this option.ObjectiveThe objective was to analyze the knowledge of university nursing students at Spanish universities toward ODT and the factors affecting it.Methods and designThe methods and design included a multicenter, sociologic, and observational study including university nursing diploma students in a complete academic year.ParticipantsA sample of 10,566 students was selected stratified by geographic area and year. Instrument. A validated questionnaire of knowledge toward ODT (PCID-DTO RIOS), self-administered and completed anonymously.ResultsQuestionnaire completion rate: 85% (n = 9001). Only 18% (n = 1580) believed that their knowledge about ODT was good, 40% (n = 3578) believed that the information they had was normal, and 39% believed that their knowledge was sparse. Of the students, 96% believed that organ needs are not covered and 79% that they might need a transplant in the future. Only 39% (n = 3493) had attended a talk about ODT. Furthermore, 83% (n = 7435) believed that attending a talk would be interesting. The following variables were associated with having a more adequate knowledge: gender (62% men vs 57% women; P < .001); academic year (P < .001); knowing a donor (P < .001); knowing a transplant patient (P < .001); believing the possibility of needing a transplant oneself in the future (P < .001); attitude toward deceased donation (P < .001); and interest in receiving an informative talk about ODT (P < .001).ConclusionOnly 18% of nursing students in Spain believed that their knowledge about ODT was adequate. These results must be considered for possible training plans for these future professionals.  相似文献

Moore J, Tomson CRV, Tessa Savage M, Borrows R, Ferro CJ. Serum phosphate and calcium concentrations are associated with reduced patient survival following kidney transplantation.
Clin Transplant 2011: 25: 406–416. © 2010 John Wiley & Sons A/S. Abstract: The impact of disordered mineral and bone metabolism following kidney transplantation is not well defined. We studied the association of serum phosphate and calcium concentrations, and surrogate measures of arterial stiffness (augmentation index: AIx and Timing of the reflected wave: Tr), with long‐term kidney transplant recipient and allograft survival. Prevalent adult renal transplant patients (n = 270) were prospectively studied over a median 88‐month follow‐up. Detailed demographic, clinical and laboratory data, in addition to both peripheral and central non‐invasive blood pressure measurements, were recorded. Higher serum phosphate and calcium levels were associated with increased all‐cause mortality (HR: 1.21; 95% CI 1.09,1.35, p < 0.001 and HR: 1.22; 95% CI 1.01,1.48; p < 0.04, respectively; adjusted Cox model) and death‐uncensored graft loss (p < 0.001 and p = 0.03, respectively). In addition, serum calcium and phosphate were associated with death‐censored graft loss on univariable analysis (p < 0.001 and p = 0.02, respectively), but did not retain significance on multivariable analysis. AIx and Tr were not associated with mortality or graft loss on multivariable analysis. This is the first report to demonstrate that both higher serum phosphate and calcium levels are associated with increased mortality in kidney transplant recipients. It highlights the need for randomized trials assessing current interventions available for improving disordered mineral–bone metabolism post transplantation.  相似文献

BACKGROUND: A two-part study was initiated to compare kidney transplant patient and transplant professional perceptions regarding immunosuppression-related physical changes and their impact on transplant recipients. METHODS: Parallel surveys were developed and administered to transplant patients and active transplant clinicians. RESULTS: Eighty percent of surveyed patients reported immunosuppression-induced hirsutism, gingival hyperplasia, acne, alopecia, or cushingoid facies. Hirsutism (94%) and gingival hyperplasia (51%) occurred more frequently in cyclosporine patients (p < 0.01); alopecia (30%) occurred more frequently in tacrolimus patients (p < 0.01). Patient reported incidence of physical changes significantly exceeded observations by professionals for every condition (p < 0.01), however 84.4% of affected patients reported feeling "happy to endure" changes "for the sake of having a transplant." Patients also reported emotional and social effects due to physical changes, an outcome underestimated by transplant professionals (p < 0.01). Patients and professionals communicated about physical changes; however, more than half of affected patients believed communication occurred "rarely/never" while over half of the professionals believed communication occurred "every visit/most of the time." Although most physicians believed changes could be addressed, doctors recommended treatment for less than half of the affected patients. When recommended therapy changes were pursued, treatments were effective in the majority of cases. CONCLUSIONS: Incidence of immunosuppression-related physical changes is high and somewhat dependent on drug regimen. Although patients seem willing to accept cosmetic changes for the sake of having a transplant, physical changes have a psychosocial impact that is underestimated by clinicians. Immunosuppression-related physical changes remain underaddressed; effective interventions offer opportunities for improved care.  相似文献

Gordon EJ, Prohaska TR, Gallant MP, Sehgal AR, Strogatz D, Conti D, Siminoff LA. Prevalence and determinants of physical activity and fluid intake in kidney transplant recipients.
Clin Transplant 2010: 24: E69–E81. © 2009 John Wiley & Sons A/S. Abstract: Background and significance: Self‐care for kidney transplantation is recommended to maintain kidney function. Little is known about levels of self‐care practices and demographic, psychosocial, and health‐related correlates. Aim: To investigate patients’ self‐reported exercise and fluid intake, demographic and psychosocial factors associated with these self‐care practices, and health‐related quality of life. Methods: Eighty‐eight of 158 kidney recipients from two academic medical centers completed a semi‐structured interview and surveys 2 months post‐transplant. Results: Most patients were sedentary (76%) with a quarter exercising either regularly (11%) or not at current recommendations (13%). One‐third (35%) reported drinking the recommended 3 L of fluid daily. Multivariate analyses indicated that private insurance, high self‐efficacy, and better physical functioning were significantly associated with engaging in physical activity (p < 0.05); while male gender, private insurance, high self‐efficacy, and not attributing oneself responsible for transplant success were significant predictors of adherence to fluid intake (p < 0.05). Despite the significance of these predictors, models for physical activity and fluid intake explained 10–15% of the overall variance in these behaviors. Multivariate analyses indicated that younger age, high value of exercise, and higher social functioning significantly (p < 0.05) predicted high self‐efficacy for physical activity, while being married significantly (p < 0.05) predicted high self‐efficacy for fluid intake. Conclusion: Identifying patients at risk of inadequate self‐care practice is essential for educating patients about the importance of self‐care.  相似文献
