<i>Background</i>: Providing holistic care to kidney patients is important; however, without full consideration of the perspectives of people living with a kidney transplant, the provision of truly 'holistic healthcare' cannot be possible. It is imperative to understand patient experiences by including kidney patients in key strategies and future renal service planning. Ignoring these important patient views means that there is a significant risk of inappropriate renal service provision and lack ...[more]

Project description:BackgroundThe optimal timing of dialysis access placement in individuals with stage 5 CKD is challenging to estimate. Preemptive living donor kidney transplant (LDKT) is the gold-standard treatment for ESKD due to superior graft survival and mortality, but dialysis initiation is often required. Among LDKT recipients, we sought to determine which clinical characteristics were associated with preemptive transplant. Among non-preemptive LDKT recipients, we sought to determine what dialysis access was used, and their duration of use before receipt of living donor transplant.MethodsWe retrospectively extracted data on 569 LDKT recipients, >18 years old, who were transplanted between January 2014 and July 2019 at UCSF, including dialysis access type (arteriovenous fistula [AVF], arteriovenous graft [AVG], peritoneal dialysis catheter [PD], and venous catheter), duration of dialysis, and clinical characteristics.ResultsPreemptive LDKT recipients constituted 30% of our cohort and were older, more likely to be White, more likely to have ESKD from polycystic kidney disease, and less likely to have ESKD from type 2 diabetes. Of the non-preemptive patients, 26% used AVF, 0.5% used AVG, 32% used peritoneal catheter, 11% used venous catheter, and 31% used more than one access type. Median (IQR) time on dialysis for AVF/AVG use was 1.86 (0.85-3.32) years; for PD catheters, 1.12 (0.55-1.92) years; for venous catheters, 0.66 (0.23-1.69) years; and for multimodal access, 2.15 (1.37-3.72) years.ConclusionsWe characterized the dialysis access landscape in LDKT recipients. Venous catheter and PD were the most popular modality in the first quartile of dialysis, and patients using these modalities had shorter times on dialysis compared with those with an AVF. Venous catheter or PD can be considered a viable bridge therapy in patients with living donor availability given their shorter waitlist times. Earlier referral of patients with living donor prospects might further minimize dialysis need.

Project description:BackgroundThe coronavirus disease 2019 (COVID-19) pandemic has caused significant psychological distress globally. Our study assessed the prevalence of psychological distress and associated factors during COVID-19 pandemic among kidney transplant recipients and kidney donors.MethodsA cross-sectional survey of 497 participants (325 recipients and 172 donors) was conducted from 1st May to 30th June 2020 in Singapore. The survey questionnaire assessed knowledge levels of COVID-19, socio-demographic data, health status, psychosocial impact of COVID-19, and precautionary behaviors during the pandemic. Psychological distress was defined as having anxiety, depression, or stress measured by the validated Depression, Anxiety and Stress Scale-21. Linear regression analyses were used to assess factors associated with higher psychological distress.ResultsThe prevalence of psychological distress was 14.3% (95% confidence interval: 11.5-17.6%) in the overall population; it was 12.8% (9.79-16.6%) in recipients and 13.4% (9.08-19.6%) in donors with no significant difference (P = 0.67). Younger age (21-49 vs. ≥50 years), unmarried status, non-Singapore citizen, worse health conditions, and worrying about physical and mental health were associated with higher psychological distress. Malays (versus Chinese), taking precautionary measures (hand sanitization), and receiving enough information about COVID-19 were associated with lower psychological distress. No interactions were observed between recipients and donors.ConclusionsAt least one in ten recipients and donors suffer from psychological distress during COVID-19 pandemic. Focused health education to younger adults, unmarried individuals, non-Singapore citizens, and those with poor health status could potentially prevent psychological distress in recipients and donors.

Project description:BackgroundDialysis vintage is associated with worse outcomes after kidney transplantation. The reasons behind this observation include immunological and nonimmunological risk factors. To mitigate the influence of immunological factors, we examined the association between time on dialysis and clinical outcomes in a cohort of HLA-identical kidney transplant recipients.MethodsThis retrospective study included 13 321 kidney transplant recipients between 1999 and 2016, of whom 589 were HLA identical followed for at least 5 y. Patient and graft survivals were compared according to dialysis time (<12 or >12 mo) using the log-rank test and Cox regression analysis. We compared surgical complications, cytomegalovirus infection, acute rejection, disease recurrence, and the trajectories of estimated glomerular filtration rate (eGFR).ResultsMedian time on dialysis was 15 mo; 9.2% of patients received preemptive transplants, and 55.3% of patients were on dialysis for >12 mo. After a median follow-up time of 154 mo, there were no differences in unadjusted and adjusted patient and graft survivals (1, 5, 10, and 15 y) between the 2 groups. There were no differences in the incidence of surgical complications (6.2% versus 3.1%), acute rejection (6.1% versus 7.7%), cytomegalovirus infection (7.6% versus 4.0%), and disease recurrence (4.2% versus 4.0%), respectively. There were no differences in mean eGFR during 5 y or in the proportion of patients with an eGFR <30 mL/min at 5 y (9.9% versus 9.2%).ConclusionsIn this low immunological risk cohort of HLA-identical kidney transplant recipients, we did not observe any association between dialysis vintage on patient survival and graft survival.

Project description:BackgroundThe Southeastern Kidney Transplant Coalition was created in 2010 to improve kidney transplant (KTx) rates in Georgia, North Carolina, and South Carolina. To identify dialysis staff-reported barriers to transplant, the Coalition developed a survey of dialysis providers in the region.MethodsAll dialysis units in the ESRD Network (n = 586) were sent a survey to be completed by the professional responsible for helping patients get transplants.ResultsOne staff member at almost all (n = 546) of the dialysis units in Network 6 completed the survey (93% response rate). Almost all respondents reported being very comfortable (51.47%) or comfortable (46.89%) discussing the KTx process with patients. Just over half (56%) of facilities reported discussing KTx as a treatment option with patients on an annual basis. Fewer than one quarter of respondents (19%) perceived that more than 50% of their patients were interested in kidney transplant, and most of the staff surveyed (68%) reported that <25% of their dialysis patients completed the evaluation process and been wait-listed for a kidney transplant.ConclusionThe survey results provide insight into KTx referral practices in southeastern dialysis units that may be contributing to low KTx rates in this region.

Project description:Background and objectivesThe influence of pretransplant dialysis modality on post-transplant outcomes is not clear. This study examined associations of pretransplant dialysis modality with post-transplant outcomes in a large national cohort of kidney transplant recipients.Design, setting, participants, & measurementsLinking the 5-year patient data of a large dialysis organization to the Scientific Registry of Transplant Recipients, 12,416 hemodialysis and 2092 peritoneal dialysis patients who underwent first kidney transplantation were identified. Mortality or graft failure and delayed graft function risks were estimated by Cox regression (hazard ratio) and logistic regression (odds ratio), respectively.ResultsRecipients treated with peritoneal dialysis pretransplantation had lower (21.9/1000 patient-years [95% confidence interval: 18.1-26.5]) crude all-cause mortality rate than those recipients treated with hemodialysis (32.8/1000 patient-years [30.8-35.0]). Pretransplant peritoneal dialysis use was associated with 43% lower adjusted all-cause and 66% lower cardiovascular death. Furthermore, pretransplant peritoneal dialysis use was associated with 17% and 36% lower unadjusted death-censored graft failure and delayed graft function risk, respectively. However, after additional adjustment for relevant covariates, pretransplant peritoneal dialysis modality was not a significant predictor of death-censored graft failure delayed graft function, respectively. Similar trends were noted on analyses using a propensity score matched cohort of 2092 pairs of patients.ConclusionsCompared with hemodialysis, patients treated with peritoneal dialysis before transplantation had lower mortality but similar graft loss or delayed graft function. Confounding by residual selection bias cannot be ruled out.

Project description:This article presents a dataset of body composition in chronic kidney disease (CKD) non-dialysis-dependent (NDD), hemodialysis (HD) and peritoneal dialysis (PD) (for at least 3 months), and kidney transplantation (KTx) (for at least 6 months) patients. The data were collected as part of a PhD research project, an observational cross-sectional study followed by a prospective analysis (about 6 months later). Adult CKD patients (18≤age≤60 years old) from a tertiary hospital were recruited: CKD in stages 3b to 5 for NDD patients; PD patients without peritonitis in the last 30 days; HD patients in 4-hour dialysis session, 3 times per week, through an arteriovenous fistula; and KTx patients with CKD in stages 1 to 3a. Patients with presence of amputated limbs or an electronic implant, wheelchair user or inpatient, body weight above 140 kg or BMI higher than 40 kg/m2, acute infections, cancer diagnosis, acquired immunodeficiency syndrome, and others that could alter body composition were excluded. The dataset in this publication consist of some clinical measurements for characterization of the sample, body composition measurements by dual-energy X-ray absorptiometry and by bioelectrical impedance spectroscopy in tetra-polar whole-body wrist to ankle (BISWB) and segmental (BISSEG) protocols of 266 CKD patients, being 137 men and 129 women; 81 in NDD treatment, 83 in HD, 24 in PD, and 80 in KTx. Measurements were performed consecutively by the same professional after an 8-hour fast, empty urinary bladder, drainage of the peritoneal dialysate, and just after the midweek hemodialysis session. To analyze differences among subgroups according to sex and CKD treatment, unpaired T test or ANOVA and Chi-square, adjusted by Bonferroni post-test, were applied. Agreement in fat free mass and fat mass measurements between BISWB and BISSEG, for cross-sectional data and for body composition changes (prospective measurement - cross-sectional measurement), was checked using intraclass correlation coefficient and 95% confidence intervals. Agreement on individual level was evaluated using the Bland-Altman method with limits of agreement. The data can be valuable in the study of body composition in CKD under all types of treatment and also for agreement analysis among body composition measurements by different instruments and techniques. The data are analysed and interpreted in the research article Bellafronte et al., 2020 [1].

Project description:IntroductionThe majority of older adults with advanced dementia (AD) develop difficulties with eating and swallowing, often prompting concerns about nutrition and quality of life. Employing a palliative approach requires providers to attain skills in addressing symptoms and communicating with family caregivers about the trajectory of AD and associated dysphagia, as well as to elicit goals of care. Research suggests internal medicine (IM) residents often perceive minimal education during training addressing skills needed to care for patients with AD.MethodsWe developed and piloted a small-group interactive seminar utilizing a trigger video depicting a family meeting addressing eating problems in a patient with AD. Case-based learning, small-group discussion, and learner reflection were employed. We assessed the impact on 82 of the 106 IM, medicine-pediatrics, and neurology residents who participated in the seminar.ResultsParticipant evaluation indicated residents showed high satisfaction and perceived the educational content of the seminar to be robust and clinically relevant. We found statistically significant (p < .001) improvements in self-reported confidence in dementia-specific skills postseminar. Effect size was large to very large (Cohen's d = 1.3-1.7).DiscussionAn interactive, case-based seminar utilizing a video depicting a realistic family meeting improved residents' self-efficacy in skills needed to address nutritional issues, engage in goals-of-care discussions, and reflect on concerns among caregivers of patients with AD. The seminar teaches important geriatric and palliative concepts meant to improve residents' ability to care for older adults with AD in their future careers.

Project description:ImportanceRecipient outcomes after kidney transplant from deceased donors who received dialysis prior to kidney donation are not well described.ObjectiveTo compare outcomes of transplant recipients who received kidneys from deceased donors who underwent dialysis prior to kidney donation vs recipients of kidneys from deceased donors who did not undergo dialysis.Design, setting, and participantsA retrospective cohort study was conducted including data from 58 US organ procurement organizations on deceased kidney donors and kidney transplant recipients. From 2010 to 2018, 805 donors who underwent dialysis prior to kidney donation were identified. The donors who underwent dialysis prior to kidney donation were matched 1:1 with donors who did not undergo dialysis using a rank-based distance matrix algorithm; 1944 kidney transplant recipients were evaluated.ExposureKidney transplants from deceased donors who underwent dialysis prior to kidney donation compared with kidney transplants from deceased donors who did not undergo dialysis.Main outcomes and measuresThe 4 study outcomes were delayed graft function (defined as receipt of dialysis by the kidney recipient ≤1 week after transplant), all-cause graft failure, death-censored graft failure, and death.ResultsFrom 2010 to 2018, 1.4% of deceased kidney donors (805 of 58 155) underwent dialysis prior to kidney donation. Of these 805 individuals, 523 (65%) donated at least 1 kidney. A total of 969 kidneys (60%) were transplanted and 641 kidneys (40%) were discarded. Among the donors with kidneys transplanted, 514 (mean age, 33 years [SD, 10.8 years]; 98 had hypertension [19.1%] and 36 had diabetes [7%]) underwent dialysis prior to donation and were matched with 514 (mean age, 33 years [SD, 10.9 years]; 98 had hypertension [19.1%] and 36 had diabetes [7%]) who did not undergo dialysis. Kidney transplants from donors who received dialysis prior to donation (n = 954 kidney recipients) were associated with a higher risk of delayed graft function compared with kidney transplants from donors who did not receive dialysis (n = 990 kidney recipients) (59.2% vs 24.6%, respectively; adjusted odds ratio, 4.17 [95% CI, 3.28-5.29]). The incidence rates did not significantly differ at a median follow-up of 34.1 months for all-cause graft failure (43.1 kidney transplants per 1000 person-years from donors who received dialysis prior to donation vs 46.9 kidney transplants per 1000 person-years from donors who did not receive dialysis; adjusted hazard ratio [HR], 0.90 [95% CI, 0.70-1.15]), for death-censored graft failure (22.5 vs 20.6 per 1000 person-years, respectively; adjusted HR, 1.18 [95% CI, 0.83-1.69]), or for death (24.6 vs 30.8 per 1000 person-years; adjusted HR, 0.76 [95% CI, 0.55-1.04]).Conclusions and relevanceCompared with receiving a kidney from a deceased donor who did not undergo dialysis, receiving a kidney from a deceased donor who underwent dialysis prior to kidney donation was associated with a significantly higher incidence of delayed graft function, but no significant difference in graft failure or death at follow-up.

Project description:BackgroundA number of cerebral manifestations are associated with JC polyomavirus (JCPyV) which are diagnosed by detection of JCPyV in cerebrospinal fluid (CSF), often with the support of cerebral imaging. Here we present an unusual case of a kidney transplant patient presenting with progressive neurological deterioration attributed to JCPyV encephalopathy.MethodsQuantitative polymerase chain reaction JCPyV was used prospectively and retrospectively to track the viral load within the patient blood, urine, CSF, and kidney sections. A JCPyV VP1 enzyme-linked immunosorbent assay was used to measure patient and donor antibody titers. Immunohistochemical staining was used to identify active JCPyV infection within the kidney allograft.ResultsJC polyomavirus was detected in the CSF at the time of presentation. JC polyomavirus was not detected in pretransplant serum, however viral loads increased with time, peaking during the height of the neurological symptoms (1.5E copies/mL). No parenchymal brain lesions were evident on imaging, but transient cerebral venous sinus thrombosis was present. Progressive decline in neurological function necessitated immunotherapy cessation and allograft removal, which led to decreasing serum viral loads and resolution of neurological symptoms. JC polyomavirus was detected within the graft's collecting duct cells using quantitative polymerase chain reaction and immunohistochemical staining. The patient was JCPyV naive pretransplant, but showed high antibody titers during the neurological symptoms, with the IgM decrease paralleling the viral load after graft removal.ConclusionsWe report a case of atypical JCPyV encephalopathy associated with cerebral venous sinus thrombosis and disseminated primary JCPyV infection originating from the kidney allograft. Clinical improvement followed removal of the allograft and cessation of immunosuppression.

Project description:Rationale & objectiveConcerns about nonadherent behaviors often prevent dialysis patients from entering waitlists for transplant even though there is an inconsistent association of these behaviors with posttransplant outcomes. We examined the association between plausible metrics of nonadherence related to dialysis treatment and posttransplant outcomes.Study designRetrospective cohort. We linked national dialysis treatment data with transplant registry data.Setting and participantsAdult patients receiving maintenance hemodialysis from January 1, 2004, through December 31, 2014, who received a kidney transplant at a US center.ExposuresWe examined 5 nonadherence metrics: serum potassium level (≥5.2 mEq/L), serum phosphorus level (>5.5 mg/dL), interdialytic weight gain (IDWG; ≥5 L), shortened treatments (≥30 min), and missed treatments (≥1); missed treatment data were available only for 2004-2009. These metrics were characterized per proportion of time under observation. Dialysis observation time was divided into 3-month intervals (quarters), and the number of nonadherent measurements in each domain was calculated for each quarter.OutcomesAllograft loss, mortality, and acute rejection in the first posttransplant year.Analytical approachUsing Cox proportional hazards and logistic regression, we estimated the hazard ratios for graft loss and mortality and odds ratios for rejection.Results9,543 patients met inclusion criteria. In our primary model, hyperphosphatemia (adjusted hazard ratio [aHR], 1.27 [95% CI, 1.08-1.49]), large IDWG (aHR, 1.39 [95% CI, 1.23-1.59]), and shortened treatments (aHR, 1.54 [95% CI, 1.12-2.13]) were associated with greater rates of allograft loss, but hyperkalemia was not. Large IDWG (aHR, 1.49 [95% CI, 1.29-1.73]) and shortened treatments (aHR, 1.34 [95% CI, 1.13-1.58]) were associated with mortality, whereas hyperkalemia and hyperphosphatemia were not. Only shortened treatments were associated with an increased risk of acute rejection (adjusted odds ratio, 3.88 [95% CI, 1.98-7.58]). In models limited to the years 2004-2009 that included missed treatments, missed treatments were associated only with mortality.LimitationsUnmeasured confounding (eg, dietary data); adherence metrics used may have multiple, complex causes.ConclusionsPlausible measures of dialysis nonadherence have long-term associations with allograft and patient survival. Behavioral metrics were more closely associated with outcomes than laboratory markers were. The implications of nonadherent behaviors for dialysis patients must be carefully considered before patients are excluded from transplantation.
