Intrinsic capacity and frailty in older adults with end-stage kidney disease undergoing pre-kidney transplant comprehensive geriatric assessment. J Nutr Health Aging 2024; 28:100236. [PMID: 38643611 DOI: 10.1016/j.jnha.2024.100236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 04/11/2024] [Accepted: 04/11/2024] [Indexed: 04/23/2024]
Abstract
OBJECTIVE Frailty has been extensively studied in end-stage kidney disease (ESKD) and kidney transplant (KT) patients. The identification of frailty is useful to predict adverse outcomes among ESKD and KT patients. The recent concept of intrinsic capacity (IC) appears as a good and easy-to-understand tool to screen for and monitor frailty in older adults with ESKD. This study aims to assess the relationships between frailty and IC in older adults with ESKD awaiting KT. DESIGN Cross-sectional study SETTING AND PARTICIPANTS: 236 patients from a day-care geriatric unit undergoing pre-KT geriatric assessment between 2017 and 2022 were included in the main sample, and 151 patients in an independent multicentric replication sample. MEASUREMENTS Frailty was evaluated using the physical frailty phenotype (PFP) and IC measures using the World Health Organization's screening (step 1) and diagnostic (step 2) tools for five IC domains (vitality, locomotion, audition, cognition, psychology). Multivariate regressions were run to assess relationships between PFP and IC domains, adjusted for age, sex, and comorbidities. Analyses were replicated using another independent multicenter cohort including 151 patients with ESKD to confirm the results. RESULTS Impairments in the locomotion, psychology, and vitality IC domains according to WHO screening tools were associated with frailty (odds ratio 9.62 [95% CI 4.09-24.99], 3.19 [95% CI 1.11-8.88], and 3.11 [95% CI 1.32-7.29], respectively). When IC were measured linearly with z-scores, all IC domains except hearing were inversely associated with frailty. In the replication cohort, results were overall similar, with a greater association between psychology domain and frailty. CONCLUSION This study highlights the relationship between frailty and IC in ESKD patients. We assume that IC may be assessed and monitored in ESKD patients, to predict and prevent future frailty, and post-KT adverse outcomes.

Abstract
Kidney transplantation is the best treatment for kidney failure in older patients. However, little is known regarding changes in health-related quality of life (HRQoL) from before to after transplantation and determinants of HRQoL in older kidney transplant recipients (KTR). We studied both, using data of older (≥65 years) patients waitlisted for kidney transplantation and older KTR 1 year after transplantation from the TransplantLines Biobank and Cohort Study. HRQoL was assessed using the SF-36 questionnaire. We included 145 older waitlisted patients (68% male, age 70 ± 4 years) and 115 older KTR at 1 year after transplantation (73% male, age 70 ± 4 years). Both mental (48.5 ± 8.4 versus 51.2 ± 7.7, p = 0.009) and physical (47.4 ± 8.5 versus 52.1 ± 7.2, p < 0.001) HRQoL were higher among included KTR, compared to the waitlisted patients. In paired analyses among 46 patients with HRQoL-data both before and after transplantation, there was a trend towards increased mental HRQoL (49.1 ± 8.4 to 51.6 ± 7.5, p = 0.054), and significantly increased physical HRQoL (48.1 ± 8.0 to 52.4 ± 6.7, p = 0.001) after transplantation. Among all assessed factors, the number of patient-reported immunosuppressive drug-related side effects was most strongly negatively associated with both mental and physical HRQoL. In conclusion, HRQoL is significantly higher among older KTR after kidney transplantation compared to older waitlisted patients.

Abstract
Kidney disease, whether acute or chronic, is a particularly common condition in the elderly, due to its main risk factors, the prevalence of which increases with age, and the fact that recovery from acute tubular damage is slower. Wherever possible, treatment of renal failure should be anticipated and discussed with the patient as part of a shared medical decision. Numerous treatment options are available to ensure maximum integration into the patient's life and care plan: renal transplantation for the most robust patients, hemodialysis in a care facility or at home, peritoneal dialysis at home, or medical treatment without dialysis. The choice of one of these treatments must leave the patient free to change his or her treatment modality at any time.

Abstract
Kidney transplantation offers improved survival and quality of life compared to dialysis for most recipients; however, benefits for elderly patients (>70 years) remain uncertain. Using the Australia and New Zealand Dialysis and Transplant Registry (2009-2019), elderly transplant recipients were matched to a waitlisted dialysis patient by age, cause of end-stage kidney disease, and dialysis duration (paired controls). We censored dialysis patients at the time of transplant. Survival was compared using stratified Cox regression. Elderly transplant recipients (KTRs) (n = 465) were matched to waitlisted pairs. Transplant group mortality initially exceeded dialysis due to excess infection-related deaths (1.9 transplant versus 0.3 dialysis/100 patient-years, P = .03). Beyond month 9, a progressive survival benefit in favor of transplantation was apparent. Over a median follow-up of 1.7 years, mortality was 38% lower for KTRs (95% confidence interval 0.41-0.94, P = .02), and 5-year survival was 80% KTRs vs 53% dialysis (P < .001). Recipients of living and standard criteria donor kidneys acquired immediate survival advantage compared with dialysis, while recipients of expanded criteria donor's kidneys experienced elevated risk of death for the first 17 months. Compared with remaining on dialysis, elderly KTRs incur an increased risk of early posttransplant mortality but thereafter may anticipate progressively superior survival rates.

Abstract
The Eurotransplant Senior Program (ESP) has expedited the chance for elderly patients with kidney failure to receive a timely transplant. This current study evaluated survival parameters of kidneys donated after brain death with or without matching for HLA-DR antigens. This cohort study evaluated the period within ESP with paired allocation of 675 kidneys from donors 65 years and older to transplant candidates 65 years and older, the first kidney to 341 patients within the Eurotransplant Senior DR-compatible Program and 334 contralateral kidneys without (ESP) HLA-DR antigen matching. We used Kaplan-Meier estimates and competing risk analysis to assess all cause mortality and kidney graft failure, respectively. The log-rank test and Cox proportional hazards regression were used for comparisons. Within ESP, matching for HLA-DR antigens was associated with a significantly lower five-year risk of mortality (hazard ratio 0.71; 95% confidence interval 0.53-0.95) and significantly lower cause-specific hazards for kidney graft failure and return to dialysis at one year (0.55; 0.35-0.87) and five years (0.73; 0.53-0.99) post-transplant. Allocation based on HLA-DR matching resulted in longer cold ischemia (mean difference 1.00 hours; 95% confidence interval: 0.32-1.68) and kidney offers with a significantly shorter median dialysis vintage of 2.4 versus 4.1 yrs. in ESP without matching. Thus, our allocation based on HLA-DR matching improved five-year patient and kidney allograft survival. Hence, our paired allocation study suggests a superior outcome of HLA-DR matching in the context of old-for-old kidney transplantation.

Abstract
On the occasion of the 20th anniversary of the REIN (French Renal Epidemiology and Information Network), a summary work on the contributions of the national French ESKD register was carried out. On the issue of access to renal transplantation for ESKD patients, the following key messages were retained. The registry of the REIN includes data about kidney transplant and dialysis. It thus allows evaluating the access to kidney transplant in France based on the needs of the population with stage 5 CKD treated by renal replacement therapy. The data produced by the registry is complementary to the data in the report of the Agence de la biomédecine (Agency of Biomedicine) based on the activity of the transplant centres and the population of registered patients waiting for a transplant. The proportion of preemptive transplant (transplant without prior recourse to dialysis) as well as that of preemptive registration (before starting dialysis) have increased since 2012 but remain low. The proportion of preemptive transplant as the first replacement therapy remains low and stable over time at around 3 to 4%. The access to the waiting list and the transplant varies depending on the age and co-morbidities of the patients (diabetes, obesity) as well as on the region. The rates of registration on the kidney transplant waiting list at the time of initiation of dialysis and at 1 year from the start have been increasing since 2012, irrespective of the patients’ characteristics, though it remains low in elderly, diabetic and severely obese patients. This is partly the result related to the publication of the HAS (French National Authority for Health) recommendations in 2015 and the publications on the disparities in access to transplants established thanks to the REIN registry. The causes of non-registration at the time of initiation of dialysis have changed over time with some patients not registering for contraindication steadily decreasing since 2012. Thanks to several studies conducted using data from the registry, the variations in access to the list could be explained, partly, by the health condition of the dialysis population as well as by the socio-economic context and differences in practices according to dialysis networks. The median waiting time for a kidney transplant has been gradually increasing since 2012, with a delta of about 8 months between 2012 and 2020. However, the waiting time between the initiation of dialysis and the transplant has increased less significantly. The probability of receiving a first kidney transplant depends on the age, diabetic status and obesity of the patient, and has remained stable over time.

Abstract
On the occasion of the 20th anniversary of the REIN (French Renal Epidemiology and Information Network), a summary work on the contributions of the national French ESKD register was carried out. On the issue of elderly CKD patients, the following key messages were retained. The population of elderly dialysis patients continues to grow. These patients have multiple comorbidities including pathologies specific to the elderly like undernutrition, walking and cognitive disorders. The data from the REIN registry has been the subject of numerous studies pertaining to this group showing heterogeneous prognosis and treatment, requiring to be better evaluated to target an individualised treatment. Decision support tools have been developed using the registry data to help nephrologists and patients in deciding whether to start replacement therapy and whether to refer elderly patients for assessment for a renal transplant. Finally, the risk-benefit evaluation of the different replacement therapies in this population should be monitored at the registry level and on a case-by-case basis in clinical practice.

Abstract
On the occasion of the 20th anniversary of the REIN (French Renal Epidemiology and Information Network), a summary work on the contributions of the national French ESKD register was carried out. On the issue its role in research, the following key messages were retained. The growing number of publications, dissertations, theses and teams involved shows that the REIN registry has attained its objective of being a shared research infrastructure, in the field of epidemiology as well as in public health, health economics or medical data processing. REIN is a valuable tool for the study of specific kidney diseases, particularly for epidemiological data pertaining to rare diseases that may lead to stage 5 of a chronic kidney disease. The linkage with the data from the National Healthcare Data System enables integrating and analysing the medical treatments received by patients, before the initiation of the replacement therapy and towards the end, as well as the details of the hospital stays.

Abstract
BACKGROUND In context of increasing complexity and risk of deceased kidney donors and transplant recipients, the impact of center volume (CV) on the outcomes of high-risk kidney transplants(KT) has not been well determined. METHODS We examined the association of CV and outcomes among 285 U.S. transplant centers from 2000-2016. High-risk KT were defined as recipient age ≥ 70 years, body mass index (BMI) ≥ 35 kg/m2, receiving kidneys from donors with kidney donor profile index(KDPI) ≥ 85%, acute kidney injury(AKI), hepatitisC + . Average annual CV for the specific-high-risk KT categorized in tertiles. Death-Censored-Graft-Loss(DCGL) and death at 3 months, 1, 5, and 10 years were compared between CV tertiles using Cox-regression models. RESULTS Two hundred fifty thousand five hundred seventy-four KT were analyzed. Compared to high CV, recipients with BMI ≥ 35 kg/m2 had higher risk of DCGL in low CV(aHR = 1.11,95%CI = 1.03-1.19) at 10 years; recipients with age ≥ 70 years had higher risk of death in low CV(aHR = 1.07,95%CI = 1.01-14) at 10 years. There was no difference of DCGL or death in low CV for donors with KDPI ≥ 85%, hepatitisC + , or AKI. CONCLUSIONS Recipients of high-risk KT with BMI ≥ 35 kg/m2 have higher risk of DCGL and recipients age ≥ 70 years have higher risk of death in low CV, compared to high CV. Future studies should identify care practices associated with CV that support optimal outcomes after KT.

The Importance Of Avoiding Time-Dependent Bias When Testing The Prognostic Value Of An Intervening Event - Two Acute Cellular Rejection Examples In Intestinal Transplantation. Am J Transplant 2023:S1600-6135(23)00308-8. [PMID: 36871628 DOI: 10.1016/j.ajt.2023.02.023] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 02/24/2023] [Indexed: 03/07/2023]
Abstract
In testing the prognostic value of the occurrence of an intervening event (clinical event that occurs post-transplant), 3 proper statistical methodologies for testing its prognostic value exist (time dependent covariate, landmark, and semi-Markov modelling methods). However, time-dependent bias has appeared in many clinical reports, whereby the intervening event is statistically treated as a baseline variable (as if it occurred at transplant). Using a single-center cohort of 445 intestinal transplant cases to test the prognostic value of 1st acute cellular rejection (ACR) and severe (grade of) ACR on the hazard rate of developing graft loss, we demonstrate how the inclusion of such time-dependent bias can lead to severe underestimation of the true hazard ratio (HR). The (statistically more powerful) time dependent covariate method in Cox's multivariable model yielded significantly unfavorable effects of 1st ACR (P<.0001; HR=2.492) and severe ACR (P<.0001; HR=4.531). In contrast, when using the time-dependent biased approach, multivariable analysis yielded an incorrect conclusion for the prognostic value of 1st ACR (P=.31, HR=0.877, 35.2% of 2.492) and a much smaller estimated effect of severe ACR (P=.0008; HR=1.589; 35.1% of 4.531). In conclusion, this study demonstrates the importance of avoiding time-dependent bias when testing the prognostic value of an intervening event.

Abstract
Tacrolimus (TAC)-induced renal injury is detrimental to long-term kidney function, but a treatment medication is not available. Glycyrrhizic acid (GA) is an active ingredient in licorice widely used to treat kidney disease. Thus, this study explored the mechanisms of renoprotection by GA on TAC-induced renal injury. C57BL/6 mice were subjected daily to TAC or a combination of TAC and GA for 4 weeks, and then renal function, histopathology, and autophagy were assessed to examine the effect of GA on a renal injury. Next, Human kidney proximal tubular epithelial (HK-2) cells were pretreated with GA for 2 h and then treated with TAC for 24 h. The effect of GA on TAC-induced HK-2 cell injury was assessed by measuring cell viability, apoptosis, autophagy, and lysosomes. Mice exposed to TAC and treated with GA had significantly greater improvements in renal function and tubulointerstitial fibrosis in comparison to mice not treated with GA. In addition, fibrosis-related protein expression, including α-smooth muscle actin and fibronectin, decreased after GA treatment. GA treatment also relieved autophagic clearance in TAC-induced renal injury. Several in vitro studies found that TAC inhibited cell viability, autophagy, lysosomal acidification, and promoted apoptosis. However, these results were less pronounced with GA pretreatment. In addition, bafilomycin A1 (which inhibits lysosomal function) reduced the protective effect of GA, indicating that lysosomal function plays an important role in this effect. Our data suggest that GA improves lysosomal function and regulates autophagy to protect against TAC-induced renal injury.

Abstract
The aim of this paper is to illustrate all the clinical epidemiology searches made within the French network REIN to improve CKD stage 4-5 care in older adults. We summarize various studies describing clinical practice, care organization, prognosis and health economics evaluation in order to develop personalized care plans and decision-making tools. In France, for 20 years now, various databases have been mobilized including the national REIN registry which includes all patients receiving dialysis or transplantation. REIN data are indirectly linked to the French administrative healthcare database. They are also pooled with data from the PSPA cohort, a multicenter prospective cohort study of patients aged 75 or over with advanced CKD, monitored for 5 years, and the CKD-REIN clinical-based prospective cohort which included 3033 patients with CKD stage 3-4 from 2013 to 2016. During our various research work, we identified heterogeneous trajectories specific to this growing older population, raising ethical, organizational and economic issues. Renal registries will help clinicians, health providers and policy-makers if suitable decision- making tools are developed and validated.

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

Association between kidney retransplantation and survival according to age in the French national cohort of dialysis patients. Am J Transplant 2022; 22:2028-2040.

Abstract
The mean age of patients returning to dialysis after a first kidney transplantation (KT) has increased in the past decades. We aimed to assess the association between second KT (2KT) and survival according to age at the time of return to dialysis. Data of 5334 patients registered in the French Renal Epidemiology and Information Network (REIN) (mean age 56.6 ± 13.6 years) who returned to dialysis after a first KT were collected. The association of 2KT with death was assessed using a propensity score-based analysis taking into account baseline and follow-up variables. In relisted patients (3272 patients, 61.3%), retransplantation was associated with better overall survival in comparison with patients who remained in dialysis (adjusted HR 0.75 [0.63-0.89], p = .0009). The survival advantage conferred by retransplantation gradually declined with increasing age (adjusted HR 0.41 [0.24-0.70] in patients <50, HR 0.94 (0.69-1.27) in patients aged 70 or older, p for interaction 0.034 for age considered as a continuous variable). 2KT is associated with better survival as opposed to remaining on dialysis after a first kidney graft failure. Nevertheless, this survival benefit is age dependent and diminishes with increasing age. The risk/benefit ratio should be comprehensively assessed in the oldest patients when relisting is considered.

Kidney transplantation (KT) is considered the best treatment for end-stage kidney disease (ESKD). In the increasing elderly ESKD population, KT should be reserved for carefully selected candidates who are expected to experience favorable outcomes. We aimed to prospectively evaluate pretransplant recipient factors that may predict patient survival and can eventually guide therapeutic decisions in elderly with ESKD.

Abstract
OBJECTIVES To investigate the survival benefit of transplantation versus dialysis for waitlisted kidney failure patients with a priori stratification. DESIGN Systematic review and meta-analysis. DATA SOURCES Online databases MEDLINE, Ovid Embase, Web of Science, Cochrane Collection, and ClinicalTrials.gov were searched between database inception and 1 March 2021. INCLUSION CRITERIA All comparative studies that assessed all cause mortality for transplantation versus dialysis in patients with kidney failure waitlisted for transplant surgery were included. Two independent reviewers extracted the data and assessed the risk of bias of included studies. Meta-analysis was done using the DerSimonian-Laird random effects model, with heterogeneity investigated by subgroup analyses, sensitivity analyses, and meta-regression. RESULTS The search identified 48 observational studies with no randomised controlled trials (n=1 245 850 patients). In total, 92% (n=44/48) of studies reported a long term (at least one year) survival benefit associated with transplantation compared with dialysis. However, 11 of those studies identified stratums in which transplantation offered no statistically significant benefit over remaining on dialysis. In 18 studies suitable for meta-analysis, kidney transplantation showed a survival benefit (hazard ratio 0.45, 95% confidence interval 0.39 to 0.54; P<0.001), with significant heterogeneity even after subgroup/sensitivity analyses or meta-regression analysis. CONCLUSION Kidney transplantation remains the superior treatment modality for most patients with kidney failure to reduce all cause mortality, but some subgroups may lack a survival benefit. Given the continued scarcity of donor organs, further evidence is needed to better inform decision making for patients with kidney failure. STUDY REGISTRATION PROSPERO CRD42021247247.

Abstract
Rationale & Objective Assessing the optimal therapy for older patients (aged ≥65 years) with end-stage kidney disease requires knowledge of longevity and health-related quality of life (HRQoL) outcomes. Kidney transplantation prolongs survival but its long-term impact on HRQoL in older recipients is not well defined. We aimed to prospectively evaluate HRQoL changes from enlisting until 3 years posttransplantation and examine pretransplantation predictors of posttransplantation outcomes. Study Design Prospective cohort study. Setting & Participants Patients 65 years and older enlisted at the Norwegian National Transplant Center between January 2013 and November 2016. Predictors Kidney transplantation, dialysis vintage, and pretransplantation comorbidity assessed using the Liu Comorbidity Index. Outcomes HRQoL, assessed using the Kidney Disease Quality of Life Short Form, version 1.3. Analytical Approach HRQoL scores obtained at 3 years posttransplantation were compared with those obtained pretransplantation and after 1 year using a paired-sample t test. Multivariable linear mixed-effect models were used to identify possible predictors of HRQoL changes over time. Results Among 289 patients included, 220 (mean age, 71.5 years) had undergone transplantation and 136 had completed the 3-year HRQoL follow-up by October 2020. Posttransplant HRQoL, both generic and kidney specific, substantially improved and the benefit persisted for 3 years. For wait-listed candidates remaining on dialysis, HRQoL gradually deteriorated, and recipients who died within 3 years posttransplantation experienced no improvement during the first year. Moderately elevated pretransplantation comorbidity scores and prolonged dialysis vintage independently predicted poor HRQoL outcomes posttransplantation. Recipients receiving dialysis for 1 year or longer with pretransplantation comorbidity scores ≥ 7 experienced a marked and sustained physical deterioration after transplantation. Limitations Homogenous and highly selected population. Conclusions Transplantation is associated with a sustained HRQoL improvement and should be the preferred treatment for selected older patients. The value of a pretransplant comorbidity score to predict posttransplantation outcomes warrants further evaluation and may improve the selection process.

Abstract
The elderly are the fastest-growing population on waiting lists for kidney transplantation (KTx). Recognized barriers to KTx in the elderly is early post-transplant mortality and morbidity. To analyze the outcomes of KTx in recipients older than 60 years and, simultaneously, in their younger paired recipients, receiving a graft from the same donor.We included 328 kidney transplant recipients in the study. The elderly kidney transplant recipients (EKT) group included 164 patients aged 65 standard deviation (SD4) years. They were paired with younger kidney transplant recipients (YKT) aged 45 (SD12) years.The studied groups (EKT vs YKT) did not differ from the graft function estimated 1 year after the transplantation (50.7 mL/min vs 54.0 mL/min), while the estimated glomerular filtration rate decline was significantly faster in the YKT group. One-year patient survival (93.9% vs 97.0%), 1-year graft survival (90.4% vs 82.3%), and incidences of delayed graft function and acute rejection did not differ between the EKT and YKT groups. Significantly more cardiovascular complications and post-transplant diabetes mellitus were noticed in the EKT group. The long-term patient and graft survivals were poorer in the EKT group versus the YKT group, but death-censored graft survivals were the same. After having excluded donor-derived graft factors, there were no differences in the first-year outcome of KTx between recipients younger and older than 60 years. As life expectancy is lower in the EKT group, the probability of patient and graft survival was also significantly lower in this group. However, death-censored graft survival was not different in the EKT and YKT groups.

Effect of age and care organization on sources of variation in kidney transplant waiting list registration. Am J Transplant 2021; 21:3608-3617. [PMID: 34008288 DOI: 10.1111/ajt.16694] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2021] [Revised: 05/04/2021] [Accepted: 05/04/2021] [Indexed: 01/25/2023]
Abstract
Despite national guidelines, medical practices and kidney transplant waiting list registration policies may differ from one dialysis/transplant unit to another. Benefit risk assessment variations, especially for elderly patients, have also been described. The aim of this study was to identify sources of variation in early kidney transplant waiting list registration in France. Among 16 842 incident patients during the period 2016-2017, 4386 were registered on the kidney transplant waiting list at the start of, or during the first year after starting, dialysis (26%). We developed various log-linear mixed effect regression models on three levels: patients, dialysis networks, and transplant centers. Variability was expressed as variance from the random intercepts (± standard error). Although patient characteristics have an important impact on the likelihood of registration, the overall magnitude of variability in registration was low and shared by dialysis networks and transplant centers. Between-transplant center variability (0.23 ± 0.08) was 1.8 higher than between-dialysis network variability (0.13 ± 0.004). Older age was associated with a lower probability of registration and greater variability between networks (0.04, 0.20, & 0.93 in the 18-64, 65-74, and 75-84 age groups). Targeted interventions should focus on elderly patients and/or certain regions with greater variability in waiting list access.

Abstract
BACKGROUND Older patients with advanced chronic kidney disease may be exposed to a higher risk of adverse drug events due to chronic kidney disease and aging. The integration of clinical pharmacist into pretransplant comprehensive geriatric assessment is an opportunity to perform medication optimization. OBJECTIVE The aim was to describe drug-related problems in older patients with advanced chronic kidney disease. METHODS Observational study was conducted with retrospective data from July 2017 to April 2019. Patients≥65 years with advanced chronic kidney disease, referred by nephrologists for pretransplant comprehensive geriatric assessment were included. During medication optimization, the pharmacist evaluated the appropriateness of each medication prescribed and identified drug-related problems. Any drug-related problem identified lead to a pharmaceutical intervention. RESULTS In total, 103 patients were included (74.5±2.9 years, 26.2% female, 47.6% on dialysis). Overall, 394 drug-related problems were identified in 93.2% of patients (3.8±2.4 drug-related problems per patient) during the medication optimization. Cardiovascular medications (25.1%), antithrombotics (13.5%) and drugs for peptic ulcer and reflux disease (10.2%) were the most involved drugs in drug-related problems. Drug-related problems mainly concerned drugs without indication (27.1%), inappropriate method of administration (24.4%) and non-conformity to guidelines (20.1%). CONCLUSION A high prevalence of drug-related problems in older patients with advanced chronic kidney disease was identified during medication optimization. The systematic integration of a clinical pharmacist in the multidisciplinary team performing pretransplant comprehensive geriatric assessment may be relevant to detect inappropriate prescriptions and to prevent from adverse drug events.

Abstract
The number of kidney transplant (KT) procedures with controlled donation after circulatory death (cDCD) donors has exponentially increased in Spain in recent years, with a parallel increase in donor and recipient acceptance criteria. The outcomes of cDCD-KT have been reported to be comparable to those of KT with donation after brain death (DBD) donors. However, studies in elderly recipients have yielded contradictory results. We performed a registry analysis of 852 KT recipients aged ≥65 years (575 in the DBD-KT group, 277 in the cDCD-KT group) in Catalonia, Spain. Clinical outcomes and survival were compared between DBD-KT and cDCD-KT recipients. The donor and recipient ages were similar between the two groups (71.5 ± 8.7 years for donors, 70.8 ± 4.1 years for recipients). Delayed graft function (DGF) was more frequent among cDCD-KT recipients, without a difference in the rate of primary nonfunction. The 3-year patient and death-censored graft survival rates were similar between DBD-KT and cDCD-KT recipients (78.8% vs. 76.4% and 90.3% vs. 86.6%, respectively). In multivariable analysis, previous cardiovascular disease and DGF were independent risk factors for patient death. The type of donation (cDCD vs. DBD) was not an independent risk factor for patient survival or graft loss. cDCD-KT and DBD-KT provide comparable patient and graft survival in elderly recipients.

Abstract
BACKGROUND Kidney transplantation (Ktx) in elderly has become increasingly accepted worldwide despite their higher burden of comorbidities. We investigated important risk factors affecting long-term patient and graft survival. METHODS We included all (n=747) Ktx patients >60 years from 2000 to 2012 in Sweden. Patients were age-stratified; 60-64, 65-69 and >70 years. Follow-up time was up to 10 years (median 7.9 years, 75% percentile >10 years). Primary outcome was 10-year patient survival in age-stratified groups. Secondary outcomes were 5- year patient and graft-survival in age-stratified groups and the impact of risk factors including Charlson comorbidity index on patient and graft-survival. RESULTS Mortality was higher in patients >70 years, after 10 years (HR 1.94; 95% CI 1.24-3.04; p=0.004). Males had a higher 10-year risk of death (HR 1.39; CI 95% 1.04-1.86; p=0.024). Five-year patient survival did not differ between age-groups. In multivariate Cox analysis (n=500) hazard ratio for 10-year mortality was 4.6 in patients with Charlson comorbidity index ≥7 vs <4 (95% CI 2.42-8.62; p=0.0001) CONCLUSION: Higher Charlson comorbidity index identified ESKD patients with 4.6 times higher risk of death after Ktx. We suggest that this index should be used as a part of the pre-operative evaluation in elderly.

Abstract
BACKGROUND In older patients with advanced chronic kidney disease (CKD), the decision of kidney transplantation (KT) is a challenge for nephrologists. The use of comprehensive geriatric assessment (CGA) is increasingly gaining interest into the process of decision-making about treatment modality choice for CKD. The aim of this study was to assess the prevalence of geriatric impairment and frailty in older dialysis and nondialysis patients with advanced CKD using a pretransplant CGA model and to identify geriatric impairments influencing the geriatricians' recommendations for KT. METHODS An observational study was conducted with retrospective data from July 2017 to January 2020. Patients aged ≥65 years with advanced CKD, treated or not with dialysis, and referred by the nephrologist were included in the study. The CGA assessed comorbidity burden, cognition, mood, nutritional status, (instrumental) activities of daily living, physical function, frailty, and polypharmacy. Geriatric impairments influencing the geriatricians' recommendations for KT were identified using univariate and multivariate logistic regressions. RESULTS 156 patients were included (74.2 ± 3.5 years and 62.2% on dialysis). Geriatric conditions were highly prevalent in both dialysis and nondialysis groups. The rate of geriatric impairments was higher in dialysis patients regarding comorbidity burden, symptoms of depression, physical function, autonomy, and frailty. Geriatrician's recommendations for KT were as follows: favorable (79.5%) versus not favorable or multidisciplinary discussion needed with nephrologists (20.5%). Dependence for Instrumental Activities of Daily Living (IADL) (odds ratio [OR] = 3.01 and 95% confidence interval [CI] = 1.30-7.31), physical functions (OR = 2.91 and 95% CI = 1.08-7.87), and frailty (OR = 2.66 and 95% CI = 1.07-6.65) were found to be independent geriatric impairments influencing geriatrician's recommendations for KT. CONCLUSIONS Understanding the burden of geriatric impairment provides an opportunity to direct KT decision-making and to guide interventions to prevent functional decline and preserve quality of life.

Abstract
BACKGROUND Extensive research and policies have been developed to improve access to kidney transplantation among patients with ESKD. Despite this, wide variation in transplant referral rates exists between dialysis facilities. METHODS To evaluate the longitudinal pattern of access to kidney transplantation over the past two decades, we conducted a retrospective cohort study of adult patients with ESKD initiating ESKD or placed on a transplant waiting list from 1997 to 2016 in the United States Renal Data System. We used cumulative incidence models accounting for competing risks and multivariable Cox models to evaluate time to waiting list placement or transplantation (WLT) from ESKD onset. RESULTS Among the study population of 1,309,998 adult patients, cumulative 4-year WLT was 29.7%, which was unchanged over five eras. Preemptive WLT (prior to dialysis) increased by era (5.2% in 1997-2000 to 9.8% in 2013-2016), as did 4-year WLT incidence among patients aged 60-70 (13.4% in 1997-2000 to 19.8% in 2013-2016). Four-year WLT incidence diminished among patients aged 18-39 (55.8%-48.8%). Incidence of WLT was substantially lower among patients in lower-income communities, with no improvement over time. Likelihood of WLT after dialysis significantly declined over time (adjusted hazard ratio, 0.80; 95% confidence interval, 0.79 to 0.82) in 2013-2016 relative to 1997-2000. CONCLUSIONS Despite wide recognition, policy reforms, and extensive research, rates of WLT following ESKD onset did not seem to improve in more than two decades and were consistently reduced among vulnerable populations. Improving access to transplantation may require more substantial interventions.

Abstract
Age per se should not be a contraindication to kidney transplantation. The first studies have shown a benefit for the survival of elderly eligible patients getting a kidney transplant compared to be maintained on the waiting list. However, more recent data suggest that this benefit is not as constant, notably with a significant early mortality period. The eligibility of elderly patients for transplantation must be based on the usual consideration of co-morbidities, but should also include, for some patients, a geriatric evaluation to detect clinical symptoms of frailty. The decision to transplant an elderly recipient must also integrate the characteristics of the donors, since the use of donors with increasingly expanding criteria can have a negative impact on the survival of these patients.

Abstract
Evaluation of patients for kidney transplant candidacy is a comprehensive process that involves a detailed assessment of medical and surgical issues, psychosocial factors, and patients' physical and cognitive abilities with an aim of balancing the benefits of transplantation and potential risks of surgery and long-term immunosuppression. There is considerable variability among transplant centers in their approach to evaluation and decision-making regarding transplant candidacy. The 2020 KDIGO (Kidney Disease: Improving Guidelines Outcome) clinical practice guideline on the evaluation and management of candidates for kidney transplantation provides practice recommendations that can serve as a useful reference guide to transplant professionals. The guideline, covering a broad range of topics, was developed by an international group of experts from transplant and nephrology through a review of literature published until May 2019. A work group of US transplant nephrologists convened by NKF-KDOQI (National Kidney Foundation-Kidney Disease Quality Initiative) chose key topics for this commentary with a goal of presenting a broad discussion to the US transplant community. Each section of this article has a summary of the key KDIGO guideline recommendations, followed by a brief commentary on the recommendations, their clinical utility, and potential implementation challenges. The KDOQI work group agrees broadly with the KDIGO recommendations but also recognizes and highlights the decision-making challenges that arise from lack of high-quality evidence and the need to balance equity with utility of organ transplantation.

Abstract
IMPORTANCE To be considered for a kidney transplant, patients with advanced kidney disease must participate in a formal evaluation and selection process. Little is known about how this process proceeds in real-world clinical settings. OBJECTIVE To characterize the transplant evaluation process among a representative national sample of US veterans with advanced kidney disease who were referred to a kidney transplant center. DESIGN, SETTING, AND PARTICIPANTS This qualitative study was a thematic analysis of clinician notes in the electronic health records of US veterans referred for kidney transplant evaluation. In a random sample of 4000 patients with advanced kidney disease between January 1, 2004, and December 31, 2014, cared for in the US Department of Veterans Affairs (VA) health care system, there were 211 patients who were referred to a transplant center during the follow-up period. This group was included in the qualitative analysis and was followed up until their date of death or the end of the follow-up period on October 8, 2019. MAIN OUTCOMES AND MEASURES Dominant themes pertaining to the kidney transplant evaluation and selection process identified through thematic analysis. RESULTS Among 211 study patients, the mean (SD) age was 57.9 (9.5) years, and 202 patients (95.7%) were male. The following 4 dominant themes regarding the transplant evaluation process emerged: (1) far-reaching and inflexible medical evaluation, in which patients were expected to complete an extensive evaluation that could have substantial physical and emotional consequences, made little accommodation for their personal values and needs, and impacted other aspects of their care; (2) psychosocial valuation, in which the psychosocial component of the transplant assessment could be subjective and intrusive and could place substantial demands on patients' family members; (3) surveillance over compliance, in which the patients' ability and willingness to follow medical recommendations was an important criterion for transplant candidacy and their adherence to a wide range of recommendations and treatments was closely monitored; and (4) disempowerment and lack of transparency, in which patients and their local clinicians were often unsure about what to expect during the evaluation process or about the rationale for selection decisions. For the evaluation process to proceed, local clinicians had to follow transplant center requirements even when they believed the requirements did not align with best practices or the patients' needs. CONCLUSIONS AND RELEVANCE In this qualitative study of US veterans with advanced kidney disease evaluated for transplant, clinician documentation in the medical record indicated that, to be considered for a kidney transplant, patients were required to participate in a rigid, demanding, and opaque evaluation and selection process over which they and their local clinicians had little control. These findings highlight the need for a more evidence-based, individualized, and collaborative approach to kidney transplant evaluation.

Kidney transplantation in the extremely elderly from extremely aged deceased donors: a kidney for each age. Nephrol Dial Transplant 2020; 35:687-696. [PMID: 32049336 DOI: 10.1093/ndt/gfz293] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2019] [Accepted: 12/10/2019] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND Advances in life expectancy have led to an increase in the number of elderly people with end-stage renal disease (ESRD). Scarce information is available on the outcomes of kidney transplantation (KT) in extremely elderly patients based on an allocation policy prioritizing donor-recipient age matching. METHODS We included recipients ≥75 years that underwent KT from similarly aged deceased donors at our institution between 2002 and 2015. Determinants of death-censored graft and patient survival were assessed by Cox regression. RESULTS We included 138 recipients with a median follow-up of 38.8 months. Median (interquartile range) age of recipients and donors was 77.5 (76.3-79.7) and 77.0 years (74.7-79.0), with 22.5% of donors ≥80 years. Primary graft non-function occurred in 8.0% (11/138) of patients. Cumulative incidence rates for post-transplant infection and biopsy-proven acute rejection (BPAR) were 70.3% (97/138) and 15.2% (21/138), respectively. One- and 5-year patient survival were 82.1 and 60.1%, respectively, whereas the corresponding rates for death-censored graft survival were 95.6 and 93.1%. Infection was the leading cause of death (46.0% of fatal cases). The occurrence of BPAR was associated with lower 1-year patient survival [hazard ratio (HR) = 4.21, 95% confidence interval (CI) 1.64-10.82; P = 0.003]. Diabetic nephropathy was the only factor predicting 5-year death-censored graft survival (HR = 4.82, 95% CI 1.08-21.56; P = 0.040). CONCLUSIONS ESRD patients ≥75 years can access KT and remain dialysis free for their remaining lifespan by using grafts from extremely aged deceased donors, yielding encouraging results in terms of recipient and graft survival.

Int J Immunogenet 2020; 48:201-210. [PMID: 32945128 DOI: 10.1111/iji.12512] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 08/06/2020] [Accepted: 08/16/2020] [Indexed: 01/03/2023]
Abstract
Due to a widespread organ shortage, the use of expanded criteria donors (ECDs) in kidney transplantation has increased persistently, reaching approximately 40% in recent years. Whether human leucocyte antigen (HLA) matching between donor and recipient should be part of allocation algorithms in transplantation of ECD kidneys, and especially of ECD kidneys from ≥70-year-old donors, is still in question. To this end, 135,529 kidney transplantations performed between 2000 and 2017 and reported to the Collaborative Transplant Study were analysed and the impact of HLA-A+B+DR mismatches on death-censored graft and patient survival as well as on rejection episodes was investigated. Results were stratified according to donor status (standard criteria donor (SCD) versus ECD) and age of ECD. HLA incompatibility increased the five-year death-censored graft failure risk similarly strong in recipients of ECD and SCD transplants (hazard ratio (HR) per HLA mismatch 1.078 and 1.075, respectively; p < .001 for both). Its impact on rejection treatments during the first post-transplant year was also significant but slightly weaker for recipients of ECD transplants (risk ratio (RR) per HLA mismatch 1.10 for ECD transplants and 1.13 for SCD transplants; p < .001 for both). Mortality increased gradually from zero to six HLA mismatches in recipients of SCD transplants, whereas for ECD transplants a significant increase was notable only from zero to more than zero mismatches. A significant but slightly less pronounced impact of HLA incompatibility on graft failure was observed in transplants from ≥70- compared with <70-year-old ECDs (HR per mismatch 1.047 and 1.093; p = .009 and < 0.001, respectively). The influence of HLA mismatches on rejection treatments was the same for both ECD age groups (RR = 1.10, p < .001 and p = .004, respectively). Our data indicate that HLA matching should be part of allocation algorithms not only in transplantation of kidneys from SCDs but also from ECDs.

Abstract
Background A potential pitfall of policies intended to promote referral for kidney transplant is that greater numbers of patients may be evaluated for transplant without experiencing the intended benefit of receiving a kidney. Little is known about the potential implications of this experience for patients. Methods We performed a thematic analysis of clinician documentation in the electronic medical records of all adults at a single medical center with advanced kidney disease who were referred to the local transplant coordinator for evaluation between 2008 and 2018 but did not receive a kidney. Results 148 of 209 patients referred to the local kidney transplant coordinator at our center (71%) had not received a kidney by the end of follow-up. Three dominant themes emerged from qualitative analysis of documentation in the medical records of these patients: 1) Forward momentum: patients found themselves engaged in an iterative process of testing and treatment that tended to move forward unless an absolute contraindication to transplant was identified or patients disengaged; 2) Potential for transplant shapes other medical decisions: engagement in the transplant evaluation process could impact many other aspects of patients’ care; and 3) Personal responsibility and psychological burden for patients and families: clinician documentation suggested that patients felt personally responsible for the course of their evaluation and that the process could take an emotional toll on them and their family members. Conclusions Engagement in the kidney transplant evaluation process can be a significant undertaking for patients and families and may impact many other aspects of their care. Policies to promote referral for kidney transplant should be coupled with efforts to strengthen shared decision-making to ensure that the decision to undergo transplant evaluation is framed as an explicit choice with benefits, risks, and alternatives and patients have an opportunity to shape their involvement in this process.

Abstract
Worldwide over 40% of patients receiving renal replacement therapy (RRT) are aged 65 years or older, a number that is still increasing. Renal transplantation is the preferred RRT, providing substantial survival benefit over those remaining on dialysis, including the elderly. Only 3% of patients aged 65 years or older accepted on the waiting list actually received a kidney transplant offer within the Eurotransplant allocation region. To increase the chance for elderly to receive a timely kidney transplant, the Eurotransplant Senior Program was introduced. The ESP supports local allocation of older kidneys to older donors in order to decrease cold ischemia time, while disregarding former exchange principles based on matching for HLA antigens. As a consequence, more elderly received a kidney transplant and a relative higher incidence of acute rejection resulted in additional courses of high steroids and/or depleting antibody therapy. Since death with a functioning graft due to infections is the dominant reason of graft loss in elderly, more intense clinical immunosuppression to prevent or treat acute rejection is not a very attractive option. Therefore in elderly kidney transplant candidates, we advocate reintroduction of minimal histocompatibility criteria (i.e., HLA-DR matching) followed by age-matching with mandatory local/regional allocation to also facilitate short cold ischemia.

Abstract
BACKGROUND With the aging of recipients of renal transplantation (RT) one of the emerging issues is the incidence of low urinary tract symptoms (LUTS), which may have negative consequences on the graft survival and function. The aim of our study was to assess the influence of LUTS and the treatment with transurethral resection of the prostate (TURP) on the outcome of RT. MATERIALS AND METHODS We collected data from men over 55 who underwent RT at our center from January 2007 to December 2016. We analyzed the incidence of LUTS; the rate of treatment with TURP; the eGFR (estimated glomerular filtration rate) at 6 months and 1, 3, and 5 years from transplantation; and graft survival. RESULTS Fifty-five patients out of 268 experienced LUTS, and 19 of them had a bladder outlet obstruction (BOO). Patients experiencing BOO had a significantly higher hazard ratio (HR) of graft failure (HR 5.7, CI 1.56-21.4) compared to the other recipients. Of the 18 patients treated with TURP, 10 received the procedure within 6 months from the LUTS onset. They had a significantly absolute eGFR improvement at 6 months from the intervention (+14.25 mL/min ± 8.10) compared to the patients treated later (-8.4 mL/min ± 14.43). DISCUSSION We showed the negative effects of LUTS on kidney graft function and survival. Although TURP is the standard therapy for such an issue, the best timing for it still has to be defined. Our experience supports the need for an early treatment of the LUTS for promoting the outcome of the RT.

Abstract
Purpose: The main objective of this multicentric retrospective pilot study was to evaluate the 1-year follow-up safety (i.e., minor [Clavien-Dindo I-II] and major [Clavien-Dindo ≥III] complications) of holmium laser enucleation of the prostate (HoLEP), GreenLight photoselective vaporization of the prostate (GL PVP), and transurethral resection of the prostate (TURP) performed after kidney transplantation (KT). The secondary objectives were to evaluate the efficacy and to assess the impact of these procedures on graft function. Materials and Methods: We retrospectively included all KT recipients who underwent a HoLEP or GL PVP or TURP for benign prostatic hyperplasia (BPH) in three French university centers. Results: From January 2013 to April 2018, 60 BPH endoscopic surgical procedures in KT recipients were performed: 17 HoLEP (HoLEP group), 9 GL PVP (GL PVP group), and 34 TURP (TURP group). Age, body mass index, preoperative serum creatinine, preoperative International Prostatic Symptom Score, preoperative Qmax, preoperative prostate-specific antigen, medical history of acute urinary retention (AUR), urinary tract infection (UTI), and indwelling urethral catheter were similar in all study groups. Mean preoperative prostate volume was higher in HoLEP group. The rate of overall postoperative complications was statistically higher in the HoLEP group (11/17 [64.7%] vs 1/9 [11.1%] vs 12/34 [35.3%] in HoLEP group, GL PVP group, and TURP group, respectively, p = 0.02), with higher rate of long-term UTI and AUR. Qmax improved in all groups after operation. Delta postoperative month 12-preoperative serum creatinine was similar in the all groups. Conclusions: Although our study is underpowered, the rate of postoperative complications is higher with HoLEP procedure, in comparison with GL PVP, for the treatment of BPH after KT. One-year efficacy is similar in HoLEP, GL PVP, and TURP groups. Further prospective randomized controlled trials are needed to confirm our results.

Abstract
INTRODUCTION Although kidney transplantation carries a survival benefit compared with dialysis, mortality, especially the first year after transplantation, is high in recipients older than 70. The aim of this study was to evaluate early death and graft failure, and to determine the risk factors associated with these events in this specific population. METHODS All patients older than 70 years who received a kidney transplant between January 2000 and December 2014 in the North-West of France were included (n = 171). Baseline characteristics and outcomes after transplantation were studied. Kaplan-Meier analysis was performed to assess patient and graft survival, and Cox regression analysis to evaluate risk factors for graft failure and patient death. RESULTS The mean recipient age was 73.3 ± 2.5 years. Death-censored graft survival at 1, 3, and 5 years were 82.6%, 78.7%, and 75.4%, respectively. Patient survival at 1, 3, and 5 years was 90.1%, 82.5%, and 68.1%, respectively. One year after transplantation, 17 patients (9.9%) were dead, mainly from infectious (58.5%) or cardiovascular disease (29.4%). According to the Cox multivariate analysis, the independent risk factors for death or graft failure during the first year were arrhythmia (odds ratio [OR] 2.26; 95% confidence interval [CI] 1.08-4.8), left-ventricular ejection fraction (LVEF) under 56% (OR 2.38; 95% CI 1.18-4.83), human leucocyte antigen (HLA) antibodies (OR 2.1; 95% CI 1.04-4.2), deceased donor from cardiovascular cause (OR 5.18; 95% CI 1.22-6.3), and acute rejection (OR 2.77; 95% CI 1.2-6.3). CONCLUSION In kidney transplant recipients older than 70 years, cardiac evaluation and immunosuppression optimization seem to be crucial to improve short-term patient and graft survival.

Abstract
Background In the elderly, kidney transplantation is associated with increased survival and improved health-related quality of life compared with dialysis treatment. We aimed to study the short-term health economic effects of transplantation in a population of elderly kidney transplant candidates. Methods Self-perceived health, quality-adjusted life years (QALYs) and costs were evaluated and compared 1 year before and 1 year after kidney transplantation in patients included in a single-centre prospective study of 289 transplant candidates ≥65 years of age. Results Self-perceived health and QALYs both significantly improved after transplantation. At 1 year, the costs per QALY were substantially higher for transplantation (€88 100 versus €76 495), but preliminary analyses suggest a favourable long-term health economic effect. Conclusions Kidney transplantation in older kidney transplant recipients is associated with improved health but also with increased costs the first year after engraftment when compared with remaining on the waiting list. Any long-term cost-effectiveness needs to be confirmed in studies with longer observation times.

Abstract
In the U.S., older adults aged 65 or above comprise nearly one quarter of the solid organ transplant (SOT) waitlists, and the number of transplants performed in this age group continues to increase. There are no specific guidelines for the assessment and follow up of the older SOT candidate or recipient. Older adults are at increased risk of infectious complications after SOT. Despite these complications and even with the use of suboptimal donors, overall outcomes are favorable. We provide an overview to specific consideration as they relate to the older SOT candidate and recipient.

Single-center analysis of infectious complications in older adults during the first year after kidney transplantation. Eur J Clin Microbiol Infect Dis 2018; 38:141-148. [PMID: 30353487 DOI: 10.1007/s10096-018-3405-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2018] [Accepted: 10/15/2018] [Indexed: 12/29/2022]
Abstract
Infections are among the top three causes of death of older adults in the first year after kidney transplantation (KT). Our aim was to describe infectious complications among KT recipients aged ≥ 65 during the first 12 months post-transplant. Single-center retrospective cohort study. Ninety-one KTs had been performed in patients ≥ 65 years of age between 2011 and 2015. 92.3% of the patients developed at least one infection. Infectious episodes increased the risk of future infection by 10% (p = 0.0018) with each infection portending a greater risk. At a patient level, viral (71.4%) and bacterial (70.2%) infections predominated. Urinary tract infections were the most frequent complication (30.3%), followed by cytomegalovirus infections (22.7%). Infections were the main reason for readmission. 7.7% of the patients developed rejection; and overall 3.3% lost their graft. Mortality at 1 year was 9.9%. Older KT recipients have a high incidence of infectious complications the first year after KT. Infections were the number one reason for readmission, and an infection episode predicted future infections for the individual patient. Despite these complications, the majority of older KT recipients were alive with a functioning graft at 1 year.
