The influence of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life of patients with sarcopenia receiving haemodialysis: a randomised controlled trial

OBJECTIVE

To study the effect of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life in patients with sarcopenia receiving maintenance haemodialysis (MHD).

METHODS

Eligible patients with sarcopenia in our hospital were randomly assigned to a control group (n = 24) and an intervention group (n = 25). The control group received conventional dialysis treatment, while the intervention group underwent mindfulness meditation combined with progressive muscle relaxation training during the interdialysis period in addition to conventional dialysis treatment. The effect of the intervention was evaluated after 12 weeks.

RESULTS

There were no significant differences in the baseline values of various parameters between the two groups. Exercise capacity (sit-to-stand test,handgrip,time to 10 sit-ups) significantly improved in the intervention group after 12 weeks (32.68 ± 8.32 vs 26.50 ± 6.83; 37.42 ± 10.12 vs 28.12 ± 8.51; 19.8 ± 5.40 vs 25.29 ± 7.18) (p < 0.05). In terms of the kidney disease quality of life (KDQOLTM) score, all other dimensions except sexual function, social functioning, burden of kidney disease and work status dimensions showed significant improvement compared to the baseline (p < 0.05). In the control group, only the dialysis staff encouragement (DSE) and patient satisfaction (PS) dimensions showed slight improvements compared to the baseline (p > 0.05). When compared with the control group, the intervention group showed significant improvements in 10 dimensions of exercise capacity and KDQOLTM scores for physical function, role-physical, general health, energy, symptom/problem list, sleep, DSE, pain, cognitive function, emotional well-being and patient PS after 12 weeks (61.30 ± 5.38 vs 42.98 ± 5.73; 57.50 ± 3.55 vs 50.70 ± 3.62) (p < 0.05). Some inflammatory markers, such as the levels of interleukin-6 and high-sensitivity C-reactive protein (30.29 ± 2.96 vs 17.65 ± 3.22; 8.93 ± 0.99 vs 3.02 ± 0.34), showed a decrease during the intervention, while albumin and prealbumin levels were significantly increased compared with the baseline (30.62 ± 1.65 vs 35.60 ± 1.68; 0.32 ± 0.05 vs 0.44 ± 0.07) (p < 0.05).

CONCLUSION

Combined intervention training can improve the motor ability and quality of life of patients with sarcopenia within a short period of time.

Health-related quality of life for pediatric patients with end-stage kidney disease: A systematic review and meta-analysis of the Pediatric Quality of Life Inventory (PedsQL)

INTRODUCTION

Health-related quality of life (HRQoL) studies demonstrate the impact of end-stage renal disease (ESRD) on the physical and psychosocial development of children. While several instruments are used to measure HRQoL, few have standardized domains specific to pediatric ESRD. This review examines current evidence on self and proxy-reported HRQoL among pediatric patients with ESRD, based on the Pediatric Quality of Life Inventory (PedsQL) questionnaires.

METHODS

Following PRISMA guidelines, we conducted a systematic review and meta-analysis on HRQoL using the PedsQL 4.0 Generic Core Scale (GCS) and the PedsQL 3.0 ESRD Module among 5- to 18-year-old patients. We queried PubMed, Embase, Web of Science, CINAHL, and Cochrane databases. Retrospective, case-controlled, and cross-sectional studies using PedsQL were included.

FINDINGS

Of 435 identified studies, 14 met inclusion criteria administered in several countries. Meta-analysis demonstrated a significantly higher total HRQoL for healthy patients over those with ESRD (SMD:1.44 [95% CI: 0.78-2.09]) across all dimensional scores. In addition, kidney transplant patients reported a significantly higher HRQoL than those on dialysis (PedsQL GCS, SMD: 0.33 [95% CI: 0.14-0.53]) and (PedsQL ESRD, SMD: 0.65 [95% CI: 0.39-0.90]) concordant with parent-proxy reports.

DISCUSSION

Patients with ESRD reported lower HRQoL in physical and psychosocial domains compared with healthy controls, while transplant and peritoneal dialysis patients reported better HRQoL than those on hemodialysis. This analysis demonstrates the need to identify dimensions of impaired functioning and produce congruent clinical interventions. Further research on the impact of individual comorbidities in HRQoL is necessary for developing comprehensive, integrated, and holistic treatment programs.

Effectiveness of Existing Insomnia Therapies for Patients Undergoing Hemodialysis : A Randomized Clinical Trial

BACKGROUND

Chronic insomnia is common in patients undergoing in-center hemodialysis, yet there is limited evidence on effective treatments for this population.

OBJECTIVE

To compare the effectiveness of cognitive behavioral therapy for insomnia (CBT-I), trazodone, and placebo for insomnia in patients undergoing long-term hemodialysis.

DESIGN

Randomized, multicenter, double-blinded, placebo-controlled trial. (ClinicalTrials.gov: NCT03534284).

SETTING

26 dialysis units in Albuquerque, New Mexico, and Seattle, Washington.

PARTICIPANTS

Patients with Insomnia Severity Index (ISI) score of 10 or greater, with sleep disturbances on 3 or more nights per week for 3 or more months.

INTERVENTION

Participants were randomly assigned to 6 weeks of CBT-I, trazodone, or placebo.

MEASUREMENTS

The primary outcome was the ISI score at 7 and 25 weeks from randomization.

RESULTS

A total of 923 patients were prescreened, and of the 411 patients with chronic insomnia, 126 were randomly assigned to CBT-I (n = 43), trazodone (n = 42), or placebo (n = 41). The change in ISI scores from baseline to 7 weeks with CBT-I or trazodone was no different from placebo: CBT-I, -3.7 (95% CI, -5.5 to -1.9); trazodone, -4.2 (CI, -5.9 to -2.4); and placebo, -3.1 (CI, -4.9 to -1.3). There was no meaningful change in ISI scores from baseline to 25 weeks: CBT-I, -4.8 (CI, -7.0 to -2.7); trazodone, -4.0 (CI, -6.0 to -1.9); and placebo, -4.3 (CI, -6.4 to -2.2). Serious adverse events (SAEs), particularly serious cardiovascular events, were more frequent with trazodone (annualized cardiovascular SAE incidence rates: CBT-I, 0.05 [CI, 0.00 to 0.29]; trazodone, 0.64 [CI, 0.34 to 1.10]; and placebo, 0.21 [CI, 0.06 to 0.53]).

LIMITATION

Modest sample size and most participants had mild or moderate insomnia.

CONCLUSION

In patients undergoing hemodialysis with mild or moderate chronic insomnia, there was no difference in the effectiveness of 6 weeks of CBT-I or trazodone compared with placebo. The incidence of SAEs was higher with trazodone.

Sickness Symptoms in Kidney Transplant Recipients: A Scoping Review

Sickness symptoms (depressive symptoms, anxiety, and fatigue) are common among people with chronic illness, often presenting as a symptom cluster. Sickness symptoms persist in many patients with chronic kidney disease, even after kidney transplantation (KT); however, little is known about sickness symptom-induced burden in KT recipients. This scoping review synthesizes available evidence for sickness symptoms in KT recipients, including findings on symptom prevalence, predictors, outcomes, interrelationships, and clustering. Among 38 reviewed studies, none identified sickness symptoms as a cluster, but we observed interrelationships among the symptoms examined. Fatigue was the most prevalent sickness symptom, followed by anxiety and depressive symptoms. Predictors of these symptoms included demographic, clinical, and psychosocial factors, and health-related quality of life was the most researched outcome. Future research should use common data elements to phenotype sickness symptoms, include biological markers, and employ sophisticated statistical methods to identify potential clustering of sickness symptoms in KT recipients.

Are cultural or psychosocial factors associated with patient-reported outcomes at the conclusion of kidney transplant evaluation?

BACKGROUND

Kidney transplant evaluation (KTE) is a period marked by many stressors for patients, which may lead to poorer patient-reported outcomes (PROs). Research on the association of cultural and psychosocial factors with PROs during KTE is lacking, even though cultural and psychosocial variables may mitigate the relationship between acceptance status and PROs.

METHODS

Using a prospective cohort study of 955 adults referred for KTE, we examined whether cultural factors and psychosocial characteristics, assessed at the initiation of KTE, are associated with PROs at KTE completion, controlling for demographics and medical factors. Also, we analyzed whether these factors moderate the relationship between transplant acceptance status and PROs.

RESULTS

In multivariable regression models, a stronger sense of mastery was associated with higher physical and mental QOL. A stronger sense of self-esteem was associated with higher kidney-specific QOL. Depression was associated with a lower mental QOL, but only in those who were accepted for transplant. Having low levels of external locus of control was associated with better mental QOL in those who were not accepted for transplant. Higher anxiety was associated with poorer kidney-specific QOL among those who were not accepted for KT, but trust in physician was only associated with greater satisfaction in transplant clinic service for those who were accepted for KT.

CONCLUSIONS

Targeting interventions to increase patient mastery and external locus of control, and reduce depression and anxiety in patients undergoing kidney transplant evaluation may be useful approaches to improve their experience during this stressful period.

Experiences of adults living with a kidney transplant-Effects on physical activity, physical function, and quality of life: A descriptive phenomenological study

BACKGROUND

Although kidney transplantation is the best treatment for kidney failure, scarce research has examined its effects on physical activity, physical function and quality of life.

OBJECTIVES

To investigate the experiences of a group of adults living with advanced kidney disease focusing on quality of life, physical activity and function and to see how findings differ in a group of kidney transplant recipients.

APPROACH

Individual semi-structured interviews were conducted with adults with advanced kidney disease (n = 10; 70.5 ± 8.9 years) and adults who had received a kidney transplant (n = 10; 50.7 ± 11.5 years; transplant age: 42.7 ± 20.9 months). Interviews were transcribed verbatim, thematically analysed and composite vignettes developed.

FINDINGS

Individuals with advanced kidney disease described a sense of loss and alteration to their life plans. Kidney transplant recipients reported increased freedom, independence and a return to near normality, with improved quality of life, physical activity and function compared with their pre-transplant lives. However, transplant recipients also described living with anxiety about the health of their transplant and fear it may fail.

CONCLUSION

Whilst adults living with advanced kidney disease often experience a reduced quality of life, physical activity and function, kidney transplantation can help facilitate a return to pre-disease levels of physical activity, physical function and quality of life. However, transplant recipients also reported living with anxiety around their new kidney failing. This study demonstrates the variability in the lived experiences of adults living with advanced kidney disease or a kidney transplant and highlights the need for patient-centred care.

The Kidney Transplant Equity Index: Improving Racial and Ethnic Minority Access to Transplantation

OBJECTIVES

To develop a scalable metric which quantifies kidney transplant (KT) centers' performance providing equitable access to KT for minority patients, based on the individualized pre-listing prevalence of End-Stage Renal Disease (ESRD).

SUMMARY BACKGROUND DATA

Racial and ethnic disparities for access to transplant in patients with ESRD are well described; however, variation in care among KT centers remains unknown. Furthermore, no mechanism exists that quantifies how well a KT center provides equitable access to KT for minority patients with ESRD.

METHODS

From 2013-2018, custom datasets from the United States Renal Data System and United Network for Organ Sharing were merged to calculate the Kidney Transplant Equity Index (KTEI), defined as: the number of minority patients transplanted at a center relative to the prevalence of minority patients with ESRD in each center's health service area. Markers of socioeconomic status (SES) and recipient outcomes were compared between high and low KTEI centers.

RESULTS

249 transplant centers performed 111,959 KTs relative to 475,914 non-transplanted patients with ESRD. High KTEI centers performed more KTs for Black (105.5 vs. 24, P<0.001), Hispanic (55.5 vs. 7, P<0.001), and American Indian (1.0 vs. 0.0, P<0.001) patients than low KTEI centers. In addition, high KTEI centers transplanted more patients with higher unemployment (52 vs. 44, P<0.001), worse social deprivation (53 vs. 46, P<0.001), and lower educational attainment (52 vs. 43, P<0.001). While providing increased access to transplant for minority and low SES populations, high KTEI centers had improved patient survival (HR: 0.86, 95% CI: 0.77-0.95).

CONCLUSIONS

The KTEI is the first metric to quantify minority access to KT incorporating the pre-listing ESRD prevalence individualized to transplant centers. KTEIs uncover significant national variation in transplant practices and identify highly equitable centers. This novel metric should be used to disseminate best practices for minority and low socioeconomic patients with ESRD.

The Relationship Between Change in Employment Status, Insurance Coverage, and Graft Failure or Death After Kidney Transplant

Introduction: Early change of insurance coverage after kidney transplantation may be associated with worse graft outcomes. We examine how return to employment moderates the hazard of graft failure associated with exit from Medicare within 36 months after transplantation. Design: Patients undergoing kidney transplantation covered by Medicare between January 2005 and December 2016 were identified in the United Network for Organ Sharing (UNOS) database. A composite outcome of graft failure or death was analyzed across four groups: (1) no change in coverage within the first 3 years post-transplant, and no return to work (2) no change in coverage, return to work (3) change in coverage, no return to work (4) change in coverage, return to work. Results: The sample included 46 120 patients; 28% changed insurance coverage from Medicare posttransplant. Among patients who returned to work (36%), change in coverage from Medicare to other insurance was associated with lower hazard of death or graft failure (hazard ratio: 0.93; 95% confidence interval: 0.87, 0.99; P = 0.030). Conclusions: Exit from Medicare was associated with patient and graft survival greater than 3 years after transplant, depending on return to work. Among patients returning to work, changes in insurance from Medicare to private coverage were associated with favorable outcomes.

Health-related quality of life and associated factors in HIV-positive transplant candidates and recipients from a HIV-positive donor

INTRODUCTION

HRQOL in transplant candidates and recipients who are also infected with HIV and are awaiting a kidney, or have received one from a HIV-positive donor, has not been previously investigated.

METHODS

The HRQOL of 47 HIV-positive kidney transplant candidates and 21 recipients from HIV-positive donors was evaluated using the Short Form-36 (SF-36) and face to face interviews at baseline and at 6 months. The correlation between SF-36 scores and sociodemographic, clinical and nutritional factors was determined.

RESULTS

68 patients completed the SF-36 at baseline and 6 months. Transplant candidates: transplant candidates had lower HRQOL than recipients. The main mental stressors were income, employment and waiting for a donor. Physical health complaints were body pain (BP) and fatigue. Pre-albumin and BMI was positively correlated with general health at baseline (r = 0.401, p = 0.031 and r = 0.338, p = 0.025). Besides a positive association with role physical (RP) and BP, albumin was associated with overall physical composite score (PCS) (r = 0.329, p = 0.024) at 6 months. Transplant recipients: Transplant recipients had high HRQOL scores in all domains. PCS was 53.8 ± 10.0 and 56.6 ± 6.5 at baseline and 6 months respectively. MCS was 51.3 ± 11.5 and 54.2 ± 8.5 at baseline and 6 months respectively. Albumin correlated positively with PCS (r = 0.464, p = 0.034) at 6 months and role emotional (RE) (r = 0.492, p = 0.024). Higher pre-albumin was associated with better RE and RP abilities and MCS (r = 0.495, p = 0.034). MAMC was associated with four domains of physical health and strongly correlated with PCS (r = 0.821, p = 0.000).

CONCLUSION

Strategies to improve HRQOL include ongoing social support, assistance with employment issues and optimising nutritional status.

The relationship between uremic toxins and symptoms in older men and women with advanced chronic kidney disease

Background

Patients with stage 4/5 chronic kidney disease (CKD) suffer from various symptoms. The retention of uremic solutes is thought to be associated with those symptoms. However, there are relatively few rigorous studies on the potential links between uremic toxins and symptoms in patients with CKD.

Methods

The EQUAL study is an ongoing observational cohort study of non-dialyzed patients with stage 4/5 CKD. EQUAL patients from Germany, Poland, Sweden and the UK were included in the present study (n = 795). Data and symptom self-report questionnaires were collected between April 2012 and September 2020. Baseline uric acid and parathyroid hormone and 10 uremic toxins were quantified. We tested the association between uremic toxins and symptoms and adjusted P-values for multiple testing.

Results

Symptoms were more frequent in women than in men with stage 4/5 CKD, while levels of various uremic toxins were higher in men. Only trimethylamine N-oxide (TMAO; positive association with fatigue), p-cresyl sulfate (PCS) with constipation and 3-carboxy-4-methyl-5-propyl-2-furanpropionic acid (negative association with shortness of breath) demonstrated moderately strong associations with symptoms in adjusted analyses. The association of phenylacetylglutamine with shortness of breath was consistent in both sexes, although it only reached statistical significance in the full population. In contrast, TMAO (fatigue) and PCS and phenylacetylglutamine (constipation) were only associated with symptoms in men, who presented higher serum levels than women.

Conclusion

Only a limited number of toxins were associated with symptoms in persons with stage 4/5 CKD. Other uremic toxins, uremia-related factors or psychosocial factors not yet explored might contribute to symptom burden.

Components of quality of life in hemodialysis patients from family caregivers' perspective: a qualitative study

BACKGROUND

Patients with end-stage kidney disease experience serious complications which affect their lives. Few studies have investigated the patients' quality of life qualitatively from the perspective of family caregivers as the closest individuals to the patients. The family caregivers are directly involved in the patients' disease progression and observe the changes, problems, and complications of disease and hemodialysis. This study aimed to explain the components of quality of life in hemodialysis patients from the family caregivers' perspective.

METHODS

In this qualitative inductive content analysis, 16 family caregivers of hemodialysis patients, presenting to the teaching hospitals of Tehran, Iran, were enrolled via maximum-variation purposive sampling; sampling continued until reaching data saturation. The data collection method included in-depth semi-structured interviews. Also, an inductive content analysis was carried out based on Elo and Kyngas' method.

RESULTS

A total of 311 codes, 19 subcategories, eight generic categories, and three main categories were extracted in this study. The main (and the generic categories) included mental and psychological problems (depressive mood, incompatibility and reduced tolerance, mental exhaustion, and deprivation of basic needs), social disruption (social isolation and social threats), and physical problems (general complications and disabilities and defects in the normal functioning of organs).

CONCLUSION

Family caregivers can be valuable information sources for formal caregivers to plan treatment for chronically ill patients who are mainly cared for at home. The present results can help us increase the existing knowledge on the impact of end-stage kidney disease and hemodialysis on the patients' quality of life. It seems that addressing the issues related to quality of life, mentioned by the caregivers, can positively affect the patients' quality of life and even reduce the caregivers' burden.

Impacts of mindfulness-based interventions in people undergoing hemodialysis: a systematic review

INTRODUCTION

Chronic kidney disease (CKD) is a serious public health problem worldwide, leading to a series of physical and psychological comorbidities, in addition to costly treatments, lifestyle and dietary restrictions. There is evidence that mindfulness-based interventions (MBIs) offer complementary treatment for people with chronic illnesses, including CKD, with the aim of improving overall health, reducing side effects and treatment costs. This review aims to investigate the MBIs impact on people with CKD undergoing hemodialysis, and to identify the methodological quality of the current literature in order to support future studies.

METHODS

We ran searches in five databases (MEDLINE via PubMed, PsycINFO, Embase, Web of Science and Scopus) in July 2020. The papers were selected and evaluated by two reviewers independently, using predefined criteria, including the Cochrane Group's risk of bias tool and its recommendations (CRD42020192936).

RESULTS

Of the 175 studies found, 6 randomized controlled trials met the inclusion criteria, and ranged from 2014 to 2019. There were significant improvements in symptoms of anxiety, depression, self-efficacy, sleep quality, and quality of life (n=3) in the groups submitted to the intervention, in addition to physical measures such as blood pressure, heart rate and respiratory rate (n=1).

CONCLUSIONS

MBIs can offer a promising and safe complementary therapy for people with CKD undergoing hemodialysis, acting on quality of life and physical aspects of the disease.

Mapping Health-Related Quality Of Life After Kidney Transplantation By Group Comparisons: A Systematic Review

Background

Health-related quality of life (HRQOL) is becoming an increasingly important outcome in kidney transplantation (KT). To describe HRQOL in kidney transplant recipients (KTRs), this systematic review summarizes literature that compared HRQOL among KTRs and other relevant populations [i.e. patients receiving dialysis, patients on the waiting list (WL) for KT, patients with chronic kidney disease (CKD) not receiving renal replacement therapy (RRT), the general population (GP) and healthy controls (HCs)] and themselves before KT.

Methods

The literature search was conducted in PubMed, Embase, Web of Science and the Cochrane Library. Eligible studies published between January 2000 and October 2020 were included.

Results

Forty-four studies comprising 6929 KTRs were included in this systematic review. Despite the study heterogeneity, KTRs reported a higher HRQOL after KT compared with pre-transplantation and compared with patients receiving dialysis with or without being on the WL, especially in disease-specific domains (i.e. burden and effects of kidney disease). Additionally, KTRs had similar to marginally higher HRQOL compared with patients with CKD Stages 3–5 not receiving RRT. When compared with HCs or the GP, KTRs reported similar HRQOL in the first 1 or 2 years after KT and lower physical HRQOL and lower to comparable mental HRQOL in studies with longer post-transplant time.

Conclusions

The available evidence suggests that HRQOL improves after KT and can be restored to but not always maintained at pre-CKD HRQOL levels. Future studies investigating intervention targets to improve or maintain post-transplant HRQOL are needed.

Kidney Disease Symptoms before and after Kidney Transplantation

BACKGROUND AND OBJECTIVES

Patients with kidney failure report a high symptom burden, which likely increases while on dialysis due to physical and mental stressors and decreases after kidney transplantation due to restoration of kidney function.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

We leveraged a two-center prospective study of 1298 kidney transplant candidates and 521 recipients (May 2014 to March 2020). Symptom scores (0-100) at evaluation and admission for transplantation were calculated using the Kidney Disease Quality of Life Short-Form Survey, where lower scores represent greater burden, and burden was categorized as very high: 0.0-71.0; high: 71.1-81.0; medium: 81.1-91.0; and low: 91.1-100.0. We estimated adjusted waitlist mortality risk (competing risks regression), change in symptoms between evaluation and transplantation (n=190), and post-transplantation symptom score trajectories (mixed effects models).

RESULTS

At evaluation, candidates reported being moderately to extremely bothered by fatigue (32%), xeroderma (27%), muscle soreness (26%), and pruritus (25%); 16% reported high and 21% reported very high symptom burden. Candidates with very high symptom burden were at greater waitlist mortality risk (adjusted subdistribution hazard ratio, 1.67; 95% confidence interval, 1.06 to 2.62). By transplantation, 34% experienced an increased symptom burden, whereas 42% remained unchanged. The estimated overall symptom score was 82.3 points at transplantation and 90.6 points at 3 months (10% improvement); the score increased 2.75 points per month (95% confidence interval, 2.38 to 3.13) from 0 to 3 months, and plateaued (-0.06 points per month; 95% confidence interval, -0.30 to 0.18) from 3 to 12 months post-transplantation. There were early (first 3 months) improvements in nine of 11 symptoms; pruritus (23% improvement) and fatigue (21% improvement) had the greatest improvements.

CONCLUSIONS

Among candidates, very high symptom burden was associated with waitlist mortality, but for those surviving and undergoing kidney transplantation, symptoms improved.

Opt-Out to the Rescue: Organ Donation and Samaritan Duties

Deceased organ donation is widely considered as a case of easy rescue―that is, a case in which A may bestow considerable benefits on B while incurring negligent costs herself. Yet, the policy implications of this observation remain unclear. Drawing on Christopher H. Wellman’s samaritan account of political obligations, the paper develops a case for a so-called opt-out system, i.e., a scheme in which people are defaulted into being donors. The proposal’s key idea is that we may arrange people’s options in specific ways for the sake of others.

Fatigue in Kidney Transplantation: A Systematic Review and Meta-Analysis

Fatigue is still present in up to 40–50% of kidney transplant recipients (KTR), the results of studies comparing the prevalence among patients on hemodialysis (HD) and KTR led to conflicting results. Fatigue correlates include inflammation, symptoms of depression, sleep disorders and obesity. Fatigue in KTR leads to significant functional impairment, it is common among KTR poorly adherent to immunosuppressive therapy and is associated with a serious deterioration of quality of life. The following databases were searched for relevant studies up to November 2020: Medline, PubMed, Web of Science and the Cochrane Library. Several studies have compared the prevalence and severity of fatigue between KTR and hemodialysis or healthy patients. They have shown that fatigue determines a significant functional deterioration with less chance of having a paid job and a significant change in quality of life. The aim of the review is to report methods to assess fatigue and its prevalence in KTR patients, compared to HD subjects and define the effects of fatigue on health status and daily life. There is no evidence of studies on the treatment of this symptom in KTR. Efforts to identify and treat fatigue should be a priority to improve the quality of life of KTR.

Association between serum osteoprotegerin level and mortality in kidney transplant recipients - a prospective observational cohort study

Paradoxically, higher serum levels of osteoprotegerin (OPG: a vascular calcification inhibitor) have been associated with increased arterial stiffness, risk of cardiovascular disease and all-cause mortality. A few studies reported that post-transplant OPG levels are associated with mortality in kidney transplant (KT) recipients. In this study, this association was assessed in a cohort of prevalent KT recipients, adjusting for previously untested potential confounders, including fibroblast growth factor 23 (FGF23) and interleukin 6 (IL-6). Socio-demographic and clinical parameters, medical and transplant history, and laboratory data were collected from 982 prevalent KT recipients. The association between serum OPG and all-cause mortality over a 6-year follow-up period was examined using Kaplan-Meier survival curves and multivariable-adjusted Cox regression models. Participants with high serum OPG were more likely female, older, deceased donor KT recipients and have more comorbidity, lower eGFR, higher FGF23, higher IL-6, and longer dialysis vintage. Each 1 pmol/l higher serum OPG level was associated with a 49% higher risk of mortality (hazard ratio (HR) [95% confidence interval (CI)]: 1.49 [1.40-1.61]). This association persisted after adjusting for confounders (HR [95% CI]: 1.20 [1.10-1.30]). In conclusion, serum OPG was associated with all-cause mortality independent of several novel confounders in prevalent KT recipients.

Your Path to Transplant: A randomized controlled trial of a tailored expert system intervention to increase knowledge, attitudes, and pursuit of kidney transplant

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

Quality of life and spirituality of patients with chronic kidney disease: pre- and post-transplant analysis

OBJECTIVE

to compare the quality of life (QoL) of patients under dialysis and after kidney transplant; correlate the QoL of transplant patients to sociodemographic, morbid and spirituality/religiosity variables.

METHOD

prospective study with a quantitative approach, with a sample of 27 patients who underwent peritoneal dialysis or dialysis undergoing kidney transplant. QoL and spirituality were assessed by the KDQOL-SF and WHOQOL-SRPB tools, being correlated with sociodemographic and economic variables.

RESULTS

the dimensions of total mental component, kidney disease effects and kidney disease burden showed significant improvement in the post-transplant period, with p <0.0004. There was a significant correlation between four dimensions of spirituality and seven dimensions of QoL; p ranged from 0.04 to 0.006.

CONCLUSION

there was a significant improvement in QoL in the post-transplant period. The dimensions of spirituality: wholeness and integration, spiritual connection, wonder and inner peace were positively correlated with seven dimensions of QoL.

Protein Intake, Fatigue and Quality of Life in Stable Outpatient Kidney Transplant Recipients

Fatigue is a frequent complaint in kidney transplant recipients (KTR), often accompanied by poor quality of life (QoL). The role of nutrition as determinant of fatigue in KTR is largely unexplored. The aims of this study are to examine the association of protein intake with fatigue and QoL in KTR and to identify other determinants of fatigue. This cross-sectional study is part of the TransplantLines Cohort and Biobank Study (NCT03272841). Protein intake was calculated from urinary urea nitrogen (UUN) in 24-h urine samples. Fatigue was assessed by the Checklist Individual Strength (CIS) questionnaire; moderate and severe fatigue were defined as a CIS score of 20–34 and ≥ 35, respectively. QoL was assessed with the RAND-36-Item Health Survey (RAND-36). Associations of protein intake with fatigue and QoL were analyzed using multinomial logistic and linear regression analyses. We included 730 stable outpatient KTR (median age 58 year [IQR 48–65], 57% male) with a mean protein intake of 82.2 ± 21.3 g/d. Moderate and severe fatigue were present in 254 (35%) and 245 (34%) of KTR. Higher protein intake was significantly associated with lower risk of moderate fatigue (OR 0.89 per 10 g/d; 95%CI 0.83–0.98, p = 0.01), severe fatigue (OR 0.85; 95%CI 0.78–0.92, p < 0.001) and was associated with higher physical component summary score of QoL (β 0.74 per 10 g/d; 95%CI 0.39–1.09, p < 0.001). Higher BMI, a history of dialysis, glomerulonephritis as primary kidney disease and a history of combined organ transplantation were also associated with severe fatigue. In conclusion, amongst the potential modifiable factors of fatigue, higher protein intake is independently associated with lower risk of moderate and severe fatigue and with better QoL in KTR. These findings underline the need to incorporate nutritional assessment in the diagnostic work-up of fatigue. Intervention studies are needed to assess the benefits and safety of higher protein intake in KTR.

Comparisons of quality of life between patients underwent peritoneal dialysis and hemodialysis: a systematic review and meta-analysis

OBJECTIVE

End-stage renal disease (ESRD) leads to renal replacement therapy and certainly has an impact on patients' health-related quality of life (HRQoL). This study aimed to review and compare the HRQoL between peritoneal dialysis (PD) and hemodialysis (HD) patients using the 36-Item Short Form Health Survey (SF-36), EuroQoL-5-dimension (EQ-5D) and the Kidney Disease Quality of Life Instrument (KDQOL).

METHODOLOGY

Systematic review was conducted by identify relevant studies through MEDLINE and SCOPUS up to April 2017. Studies were eligible with following criteria: studied in ESRD patients, compare any pair of renal replacement modalities, and reported HRQoL. The unstandardized mean differences (USMD) of HRQoL among modalities were calculated and pooled using a random-effect models if heterogeneity was present, otherwise a fixed-effect model was applied.

RESULTS

A total of twenty-one studies were included with 29,000 participants. Of them, mean age and percent male were 48.1 years and 45.1, respectively. The pooled USMD (95% CI) of SF-36 between PD and HD (base) were 1.86 (0.47, 3.24) and 0.42 (- 1.99, 2.82) for mental component and physical component summary scores, respectively. For EQ-5D, the pooled USMD of utility and visual analogue scale (VAS) score were 0.02 (- 0.06, 0.10) and 3.56 (1.73, 5.39), respectively. The pooled USMD of KDQOL were 9.67 (5.67, 13.68), 6.71 (- 5.92, 19.32) 6.30 (- 0.41, 12.18), 2.35 (- 4.35, 9.04), 2.10 (0.07, 4.13), and 1.21 (- 2.98, 5.40) for burden of kidney disease, work status, effects of kidney disease, quality of social interaction, symptoms, and cognitive function.

CONCLUSION

Patients with chronic kidney disease (CKD) stage 5 or ESRD treated with PD had better generic HRQoL measured by SF-36 and EQ-5D than HD patients. In addition, PD had higher specific HRQoL by KDQOL than HD patients in subdomain of physical functioning, role limitations due to emotional problems, effects and burden of kidney disease.

Evaluating symptom burden in kidney transplant recipients: validation of the revised Edmonton Symptom Assessment System for kidney transplant recipients - a single-center, cross-sectional study

We assessed the validity of the Edmonton Symptom Assessment System (ESAS-r) in kidney transplant recipients (KTR). A cross-sectional sample of 252 KTR was recruited. Individual ESAS-r symptom scores and symptom domain scores were evaluated. Internal consistency, convergent validity, and construct validity were assessed with Cronbach's α, Spearman's rank correlations, and a priori-defined risk group comparisons. Mean (SD) age was 51 (16), 58% were male, and 58% Caucasian. ESAS-r Physical, Emotional, and Global Symptom Scores demonstrated good internal consistency (α > 0.8 for all). ESAS-r Physical and Global Symptom Scores strongly correlated with PHQ-9 scores (0.72, 95% CI: 0.64-0.78 and 0.74, 95% CI: 0.67-0.80). For a priori-defined risk groups, individual ESAS-r symptom score differed between groups with lower versus higher eGFR [pain: 1 (0-3) vs. 0 (0-2), delta = 0.18; tiredness: 3 (1-5) vs. 1.5 (0-4), delta = 0.21] and lower versus higher hemoglobin [tiredness: 3 (1-6) vs. 2 (0-4), delta = 0.27]. ESAS-r Global and Physical Symptom Scores differed between groups with lower versus higher hemoglobin [13 (6-29) vs. 6.5 (0-18.5), delta = 0.3, and 9 (2-19) vs. 4 (0-13), delta = 0.24] and lower versus higher eGFR [11 (4-20) vs. 6.5 (2-13), delta = 0.21, and 7 (2-16) vs. 3 (0-9), delta = 0.26]. These data support reliability and construct validity of ESAS-r in KTR. Future studies should explore its clinical utility for symptom assessment among KTR.

Prevalence and Persistence of Uremic Symptoms in Incident Dialysis Patients

Background

Uremic symptoms are major contributors to the poor quality of life among patients on dialysis, but whether their prevalence or intensity has changed over time is unknown.

Methods

We examined responses to validated questionnaires in two incident dialysis cohort studies, the Choices for Health Outcomes in Caring for ESRD (CHOICE) study (N=926, 1995-1998) and the Longitudinal United States/Canada Incident Dialysis (LUCID) study (N=428, 2011-2017). We determined the prevalence and severity of uremic symptoms-anorexia, nausea/vomiting, pruritus, sleepiness, difficulty concentrating, fatigue, and pain-in both cohorts.

Results

In CHOICE and LUCID, respectively, mean age of the participants was 58 and 60 years, 53% and 60% were male, and 28% and 32% were black. In both cohorts, 54% of the participants had diabetes. Median time from dialysis initiation to the symptoms questionnaires was 45 days for CHOICE and 77 days for LUCID. Uremic symptom prevalence in CHOICE did not change from baseline to 1-year follow-up and was similar across CHOICE and LUCID. Baseline symptom prevalence in CHOICE and LUCID was as follows: anorexia (44%, 44%, respectively), nausea/vomiting (36%, 43%), pruritus (72%, 63%), sleepiness (86%, 68%), difficulty concentrating (55%, 57%), fatigue (89%, 77%), and pain (82%, 79%). In both cohorts, >80% of patients had three or more symptoms and >50% had five or more symptoms. The correlation between individual symptoms was low (ρ<0.5 for all comparisons). In CHOICE, no clinical or laboratory parameter was strongly associated with multiple symptoms.

Conclusions

The burden of uremic symptoms among patients on dialysis is substantial and has not changed in the past 15 years. Improving quality of life will require identification of the factors that underlie the pathogenesis of uremic symptoms and better ways of removing the toxins that are responsible.

Psychological and Psychopathological Aspects of Kidney Transplantation: A Systematic Review

Kidney transplantation is a serious event that involves profound psychological, relational and social changes both for the patient and his family context. Assessment of personality profile, awareness of disease, family and social support of the patient candidate for kidney transplantation are necessary because factors not adequately considered, can influence the success of the transplant and alter the psychological stability of the patient. The present study aims to provide a systematic review of the literature of the last twelve years (2006-2018), focusing in particular on patient's readiness level and illness management and on possible psychopathology. Sixty-two studies were examined. Based on the Downs and Black checklist, most studies (n = 32) were of high quality; 15 of which related to lifestyle, health education, and therapeutic adherence in post-renal transplantation, 17 studies concerned the possible existence of psychopathology and cognitive impairment of renal deceased transplanted subjects. The literature used has shown that the population of kidney transplant patients is exposed to a high risk of psychiatric disorders with repercussions on the quality of life and the risk of rejection. Therefore, an adequate pre-transplant psychosocial assessment is necessary, which allows a more in-depth knowledge of the candidate to plan coping strategies and possible post-transplant psychotherapy.

Efficacy and Safety of Intra-gastric Balloon Placement in Dialyzed Patients Awaiting Kidney Transplantation

BACKGROUND

The number of obese patients who are candidates for renal transplantation has considerably increased, but obesity can be a barrier to kidney transplantation. Weight loss is often difficult through diet alone. We studied the efficacy and tolerance of the intra-gastric balloon (IGB) procedure in obese patients who were undergoing dialysis and were candidates for a renal transplantation.

PATIENTS AND METHODS

Obese patients (BMI > 30 kg/m²) who were candidates for renal transplantation were prospectively included in the study between 2010 and 2012. The balloon was inserted and removed during a gastric endoscopy under general anesthesia. The treatment lasted 6 months. The end point was a decrease in BMI after 6 months. Body impedance spectrometry (BIS) and nutritional statute were evaluated initially and then after IGB removal.

RESULTS

Seventeen patients (nine females and eight males) with a mean age of 53.4 years [19.4-69.4] were included. The decrease in body mass index (BMI) during the 6-month placement was 3 kg/m² (from 37.7 to 34.4 kg/m²). The mean weight loss was 7 kg. The mean percentage of excess weight loss after 6 months was 20.2 (± 11.4). The tolerance was good without any complications. Eleven patients underwent kidney transplantation.

CONCLUSION

IGB in obese dialyzed patients who are candidates for renal transplantation is safe and effective. However, the amount of weight loss can vary.

Effects of Combined Resistance Plus Aerobic Training on Body Composition, Muscle Strength, Aerobic Capacity, and Renal Function in Kidney Transplantation Subjects

Lima, PS, de Campos, AS, de Faria Neto, O, Ferreira, TCA, Amorim, CEN, Stone, WJ, Prestes, J, Garcia, AMC, and Urtado, CB. Effects of combined resistance plus aerobic training on body composition, muscle strength, aerobic capacity, and renal function in kidney transplantation subjects. J Strength Cond Res XX(X): 000-000, 2019-Immunosuppression and a sedentary lifestyle may exacerbate complications such as early graft dysfunction and muscle loss, and reduce patient survival after kidney transplantation (KT). Therefore, the purpose of this study was to evaluate changes in body composition (BC), muscular strength, aerobic, and renal function in KT subjects submitted to combined resistance plus aerobic training. Twelve KT subjects were randomly assigned into groups: (G1) 12 weeks of combined training (3 males and 4 females, 54 ± 3 years); or (G2) nonexercise control (5 females, 43 ± 18 years). The subjects were evaluated for BC (dual-energy X-ray absorptiometry), estimated V[Combining Dot Above]O2peak, right-hand maximal grip strength (RHMGS) and left-hand maximal grip strength (LHMGS), and renal function. Post-training revealed that G1 reduced body fat percentage (p = 0.046), uric acid (Δ = -0.87; p = 0.023), urea (Δ = -9.43; p = 0.032), and creatinine (Δ = -0.15; p = 0.045), increased fat-free mass, estimated V[Combining Dot Above]O2peak, RHMGS, LHMGS (p < 0.05), and estimated glomerular filtration rate (eGFR) (Δ = 11.64; p = 0.017). G2 increased urea (Δ = 8.20; p = 0.017), creatinine (Δ = 0.37; p = 0.028), and decreased eGFR (Δ = -16.10; p = 0.038). After 12 weeks, urea (Δ = 24.94; p = 0.013), uric acid (Δ = 1.64; p = 0.044), and creatinine (Δ = 0.9; p = 0.011) were lower, whereas eGFR (Δ = 36.51; p = 0.009) was higher in G1. These data indicate that combined training instigates positive changes in BC, muscular strength, aerobic capacity, and renal function after KT.

The psychosocial needs and quality of life of family caregivers of patients with organ transplant

Background

Families of patients with organ transplants experience many problems, both with the onset of illness and during the hospitalisation of their relative for an organ transplant. The healthcare providers try their best to give high-quality care to patients. However, they neglect quality of life and psychosocial needs of family caregivers.

Aims

This study aimed to assess the psychosocial needs and quality of life of the family caregivers of post-transplant patients and the relationship between these two variables.

Methods

This descriptive correlational study was conducted on liver, kidney and bone marrow transplant wards in the largest transplant centre affiliated with a university of medical science in south-eastern Iran. The sample included 230 family caregivers of post-transplant patients, who were selected using quota sampling. Data were collected using the 45-item questionnaire of psychosocial needs (the Critical Care Family Needs Inventory) with five dimensions (assurance, comfort, information, proximity and support), and the Short Form-36 Quality of Life questionnaire with eight scales (physical functioning, physical problems, emotional problems, social functioning, pain, vitality, mental health and perception of health). In the Critical Care Family Needs Inventory, 1 indicates not important and 4 very important. In the Short Form-36 Quality of Life questionaire, 0 indicates the worst health and 100 the best health.

Results

The participants rated the mean of their psychosocial needs as important (3.18 ± 0.27). Also, the mean of quality of life of participants was at an undesirable level (45.17 ± 92.66). The psychosocial needs of the caregivers showed a poor, inverse significant relationship with their quality of life (r = -0.16, p = 0.01).

Conclusion

The results showed that with increasing psychosocial needs of family caregivers of post-transplant patients, their quality of life declines. Healthcare providers should implement developed plans and appropriate strategies to fulfil psychosocial needs and improve the quality of life of family caregivers of these patients.

Ethnic background is associated with no live kidney donor identified at the time of first transplant assessment-an opportunity missed? A single-center retrospective cohort study

Patients from ethnocultural minorities have reduced access to live donor kidney transplant (LDKT). To explore early pretransplant ethnocultural disparities in LDKT readiness, and the impact of the interactions with the transplant program, we assessed if patients had a potential live donor (LD) identified at first pretransplant assessment, and if patients with no LD initially received LDKT subsequently. Single-center, retrospective cohort of adults referred for kidney transplant (KT) assessment. Multivariable logistic regression assessed the association between ethnicity and having a potential LD. Cox proportional hazard analysis assessed the association between no potential LD initially and subsequent LDKT. Of 1617 participants, 66% of Caucasians indicated having a potential LD, compared with 55% of South Asians, 44% of African Canadians, and 41% of East Asians (P < 0.001). In multivariable logistic regression analysis, the odds of having a potential LD identified was significantly lower for African, East and South Asian Canadians. No potential LD at initial KT assessment was associated with lower likelihood of LDKT subsequently (hazard ratio [HR], 0.14; [0.10-0.19]). Compared to Caucasians, African, East and South Asian and African Canadians are less likely to have a potential LD identified at first KT assessment, which predicts a lower likelihood of subsequent LDKT.

Sleep Quality and Related Psychosocial Variables Among Renal Transplant Patients

BACKGROUND

Several studies have examined sleep quality in the post renal transplant population of China, but few studies have actually confirmed the related psychosocial variables of sleep quality in renal transplant recipients with home care.

OBJECTIVES

This study investigates sleep quality and its related psychosocial variables among renal transplant patients.

METHODS

This is a cross-sectional study using a convenient sampling approach. Self-report questionnaires were applied to 485 renal transplant patients. All participants completed the General Data Questionnaire, the Pittsburgh Sleep Quality Index (PSQI), the Self-Rating Depression Scale, the Three-Dimensional Inventory of Character Strengths, and the Flourishing Scale.

RESULTS

A total of 438 valid questionnaires were included in the analysis. The global PSQI score was 5.86 (SD, 3.20), significantly lower than the norm; 128 (29.2%) recipients were classified as having poor sleep quality (global PSQI > 7). In the component score of PSQI, sleep onset latency was the highest; the others from high to low are sleep disturbance, daytime dysfunction, subjective sleep quality, sleep efficiency, sleep duration, and use of hypnotic medication. A total of 19.6% reported sleeping fewer than 6 hours a night, 64.8% reported that they had to get up to use the bathroom, and 50.0% woke up in the middle of the night or early morning at least 1 night per week in the past month. Significant differences in the PSQI scores were observed in renal transplant patients of different sex, age, residence, career, length of post-renal transplant period, comorbidity, kidney function, and depressive symptoms (P < .05). The PSQI scores were positively correlated with depression (Self-Rating Depression Scale) (P < .01) but negatively correlated with inquisitiveness (Three-Dimensional Inventory of Character Strengths-inquisitiveness) and psychological well-being (Flourishing Scale) (P < .01).

CONCLUSION

The sleep quality of renal transplant patients was lower than that of the general population. Character strengths and well-being can increase the level of sleep quality in renal transplant patients. Psychosocial intervention is necessary for improving the sleep quality of renal transplant recipients in China.

Children on dialysis as well as renal transplanted children report severely impaired health-related quality of life

Objectives

To assess health-related quality of life (HRQoL) across three renal replacement therapy modalities (preemptive transplant, non-preemptive transplant, and dialysis) in comparison with the healthy norm and other chronic health conditions, and to explore related patient factors.

Study design

All prevalent end-stage renal disease (ESRD) patients aged 8–18 years who spent at least 6 months on their current treatment modality in the Netherlands, Belgium, and part of Germany were approached to complete the Pediatric Quality of Life Inventory 4.0 (PedsQL™) questionnaire. We determined the differences between groups on PedsQL™ mean scores, the proportion of children with an impaired HRQoL (≥ 1 SD lower than the healthy norm), the proportion of problems on individual items of the PedsQL™, and the effect of time on current treatment. Linear regression models were used to explore determinants of HRQoL.

Results

192 out of 278 patients (20% preemptive transplant, 58% non-preemptive transplant, 22% dialysis) filled in the PedsQL™ (response rate 69%). Independent of treatment modality, patients had significantly lower mean scores and consequently higher proportions of impaired HRQoL on almost all domains compared to the healthy norm and other chronic health conditions. Patients with a preemptive transplant only reported higher scores on physical health compared to the other treatment modalities. Having comorbidities was the most important determinant associated with lower HRQoL scores.

Conclusion

Dialysis and renal transplantation both have a severe impact on the HRQoL of children with ESRD. Physicians should be aware of this continuous burden. Furthermore, to develop tailored interventions for children with ESRD, qualitative studies are needed to gain more insight in the determinants of HRQoL in the different treatment modalities.

Patient-Reported Outcomes in Patients with Chronic Kidney Disease and Kidney Transplant-Part 1

Chronic kidney disease (CKD) is a complex medical condition that is associated with several comorbidities and requires comprehensive medical management. Given the chronic nature of the condition, its frequent association with psychosocial distress, and its very significant symptom burden, the subjective patient experience is key toward understanding the true impact of CKD on the patients’ life. Patient-reported outcome measures are important tools that can be used to support patient-centered care and patient engagement during the complex management of patients with CKD. The routine collection and use of patient-reported outcomes (PROs) in clinical practice may improve quality of care and outcomes, and may provide useful data to understand the disease from both an individual and a population perspective. Many tools used to measure PROs focus on assessing health-related quality of life, which is significantly impaired among patients with CKD. Health-related quality of life, in addition to being an important outcome itself, is associated with clinical outcomes such as health care use and mortality. In Part 1 of this review, we provide an overview of PROs and implications of their use in the context of CKD. In Part 2, we will review the selection of appropriate measures and the relevant domains of interest for patients with CKD.

Brief Mindfulness Meditation for Depression and Anxiety Symptoms in Patients Undergoing Hemodialysis: A Pilot Feasibility Study

BACKGROUND AND OBJECTIVES

Up to 50% of patients undergoing hemodialysis suffer from symptoms of depression and/or anxiety. Access to traditional pharmacotherapies and psychotherapies for depression or anxiety in this patient population has been inadequate. The objective of this study was to investigate the feasibility and effectiveness of brief mindfulness meditation intervention for patients on hemodialysis with depression and anxiety symptoms.

DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS

This study was a randomized, controlled, assessor-blinded trial conducted in an urban hemodialysis unit. Forty-one patients were randomly assigned to intervention (n=21) and treatment-as-usual (n=20) groups. The intervention group received an 8-week individual chairside meditation intervention lasting 10-15 minutes, three times a week during hemodialysis. Feasibility outcomes were primarily assessed: enrollment rates, intervention completion rates, and intervention tolerability. Symptoms of depression and anxiety were measured using the Patient Health Questionnaire (PHQ-9) and the General Anxiety Disorder-7 (GAD-7).

RESULTS

Of those deemed eligible for the study, 67% enrolled (41 of 61). Of the participants randomized to the intervention group, 71% completed the study, with meditation being well tolerated (median rating of 8 of 10 in a Likert scale; interquartile range=10-5 of 10). Barriers to intervention delivery included frequent hemodialysis shift changes, interruptions by staff or alarms, space constraints, fluctuating participant medical status, and participant fatigue. Meditation was associated with subjective benefits but no statistically significant effect on depression scores (change in PHQ-9, -3.0±3.9 in the intervention group versus -2.0±4.7 in controls; P=0.45) or anxiety scores (change in GAD-7, -0.9±4.6 versus -0.8±4.8; P=0.91).

CONCLUSIONS

On the basis of the results of this study, mindfulness meditation appears to be feasible and well tolerated in patients on hemodialysis with anxiety and depression symptoms. The study did not reveal significant effects of the interventions on depression and anxiety scores.

Multidimensional assessment of quality of life of children and problems of parents in Indian society after pediatric renal transplant: Beyond the conventional thoughts

This study evaluated multidimensional QoL after renal transplant to find the physical, psychosocial, and economic issues after pediatric transplant. Sixty-two patients under the age of 18 at the time of assessment were asked to complete WHOQOL questionnaires. Assessment of behavioral, emotional status of child, problems of parents, and SEC of family were also performed. The beneficial effect of transplantation was observed across all domains of QoL (physical, psychological, social, environmental, and overall QoL). The greatest change was observed in QoL domains that dealt with overall satisfaction (81.28±15.76 vs 45.32±10.98; P<.0001). The domain dealing with environmental factors showed the least variation after transplantation (65.58±17.45 vs 51.34±17.81; P<.0001). Feelings of happiness and peer group socialization were reported in 81% and 69% of patients, respectively. There was no marital disharmony in 52% of families. However, SEC deteriorated in 16% of families and 59% of the families availed financial assistance. Sixty-nine percent of children had not attended school after one year of transplantation, but return to school after transplant was reduced to 8% at 5 years. Pre- and post-transplant social and psychological support may help these patients and their families adjust in society and have a positive outlook for their future.

Ethnic Background Is a Potential Barrier to Living Donor Kidney Transplantation in Canada: A Single-Center Retrospective Cohort Study

BACKGROUND

We examined if African or Asian ethnicity was associated with lower access to kidney transplantation (KT) in a Canadian setting.

METHODS

Patients referred for KT to the Toronto General Hospital from January 1, 2003, to December 31, 2012, who completed social work assessment, were included (n = 1769). The association between ethnicity and the time from referral to completion of KT evaluation or receipt of a KT were examined using Cox proportional hazards models.

RESULTS

About 54% of the sample was white, 13% African, 11% East Asian, and 11% South Asian; 7% had "other" (n = 121) ethnic background. African Canadians (hazard ratio [HR], 0.75; 95% CI: 0.62-0.92]) and patients with "other" ethnicity (HR, 0.71; 95% CI, 0.55-0.92) were less likely to complete the KT evaluation compared with white Canadians, and this association remained statistically significant in multivariable adjusted models. Access to KT was significantly reduced for all ethnic groups assessed compared with white Canadians, and this was primarily driven by differences in access to living donor KT. The adjusted HRs for living donor KT were 0.35 (95% CI, 0.24-0.51), 0.27 (95% CI, 0.17-0.41), 0.43 (95% CI, 0.30-0.61), and 0.34 (95% CI, 0.20-0.56) for African, East or South Asian Canadians and for patients with "other" ethnic background, respectively.

CONCLUSIONS

Similar to other jurisdictions, nonwhite patients face barriers to accessing KT in Canada. This inequity is very substantial for living donor KT. Further research is needed to identify if these inequities are due to potentially modifiable barriers.

Depressive Symptoms Are Associated With Objectively Measured Sleep Parameters in Kidney Transplant Recipients

STUDY OBJECTIVES

Both depression and sleep complaints are very prevalent among kidney transplant (kTx) recipients. However, details of the complex relationship between sleep and depression in this population are not well documented. Thus, we investigated the association between depressive symptoms and sleep macrostructure parameters among prevalent kTx recipients.

METHODS

Ninety-five kTx recipients participated in the study (54 males, mean ± standard devation age 51 ± 13 years, body mass index 26 ± 4 kg/m2, estimated glomerular filtration rate 53 ± 19 ml/min/1.73 m2). Symptoms of depression were assessed by the Center for Epidemiologic Studies - Depression Scale (CES-D). After 1-night polysomnography each recording was visually scored and sleep macrostructure was analyzed.

RESULTS

The CES-D score was significantly associated with the amount of stage 2 sleep (r = 0.20, P < .05), rapid eye movement (REM) latency (r = 0.21, P < .05) and REM percentage (r = -0.24, P < .05), but not with the amount of slow wave sleep (r = -0.12, P > .05). In multivariable linear regression models the CES-D score was independently associated with the amount of stage 2 sleep (β: 0.205; confidence interval: 0.001-0.409; P = .05) and REM latency (β: 0.234; confidence interval: 0.001-0.468; P = .05) after adjustment for potential confounders.

CONCLUSIONS

Depressive symptoms among kTx recipients are associated with increased amount of stage 2 sleep and prolonged REM latency. Further studies are needed to confirm our findings and understand potential clinical implications.

Quality of sleep in renal transplant recipients and patients on hemodialysis

BACKGROUND

Sleep disorders are very common in patients with chronic kidney disease and they may not always subside after kidney transplantation.

AIM AND METHODS

The aim of this cross-sectional study was to evaluate the self-reported quality of sleep, insomnia problems in particular, and examine the factors that disturb sleep of kidney transplant recipients (KTx: n=152) in comparison to age- and sex-matched patients on dialysis (HD: n=67) and participants with normal renal function (NOR: n=49), through the administration of the Athens Insomnia Scale (AIS) at least six months after transplantation. Clinical and laboratory data, as well as health-related quality of life, depression, anxiety, post-traumatic stress symptoms, and the presence of restless legs syndrome (RLS) and pruritus were investigated in relation to sleep problems.

RESULTS

The highest mean AIS score was observed in the transplant patients (KTx: 4.6±13.3 vs. HD: 3.8±8.1 vs. NOR: 2.4±10.2); both KTx and HD patients had a lower quality of sleep compared to participants with normal renal function. Multiple linear regression analysis showed that the determinants of the total AIS score were the frequency of post-traumatic stress symptoms, depression, RLS, diastolic blood pressure, and pain (all p<0.0001).

CONCLUSION

Although amelioration of renal function post-transplantation improves several aspects of quality of life, it does not seem to have a beneficial effect on self-reported sleep.

Quality of life in patients on chronic dialysis in South Africa: a comparative mixed methods study

Background

The increasing prevalence of treated end-stage renal disease and low transplant rates in Africa leads to longer durations on dialysis. Dialysis should not only be aimed at prolonging lives but also improve quality of life (QOL). Using mixed methods, we investigated the QOL of patients on chronic haemodialysis (HD) and peritoneal dialysis (PD).

Methods

We conducted a cross-sectional study at Tygerberg Hospital in Cape Town, South Africa. All the PD patients were being treated with continuous ambulatory peritoneal dialysis. The KDQOL-SF 1.3 questionnaire was used for the quantitative phase of the study. Thereafter, focus-group interviews were conducted by an experienced facilitator in groups of HD and PD patients. Electronic recordings were transcribed verbatim and analysed manually to identify emerging themes.

Results

A total of 106 patients completed questionnaires and 36 of them participated in the focus group interviews. There was no difference between PD and HD patients in the overall KDQOL-SF scores. PD patients scored lower with regard to symptoms (P = 0.005), energy/fatigue (P = 0.025) and sleep (P = 0.023) but scored higher for work status (P = 0.005) and dialysis staff encouragement (P = 0.019) than those on HD. Symptoms and complications were verbalised more in the PD patients, with fear of peritonitis keeping some housebound. PD patients were more limited by their treatment modality which impacted on body image, sexual function and social interaction but there were less dietary and occupational limitations. Patients on each modality acknowledged the support received from family and dialysis staff but highlighted the lack of support from government. PD patients had little opportunity for interaction with one another and therefore enjoyed less support from fellow patients.

Conclusions

PD patients experienced a heavier symptom burden and greater limitations related to their dialysis modality, especially with regards to social functioning. The mixed-methods approach helped to identify several issues affecting quality of life which are amenable to intervention.

The effect of renal transplantation on quality of sleep in former dialysis patients

Data on sleep quality in renal transplanted (RTX) patients are scarce, and longitudinal studies are lacking. The purpose of this study was to assess the prevalence of sleep complaints in RTX patients and identify variables associated with improvement in sleep quality. In a longitudinal study, 301 dialysis patients were followed for up to 5.5 years, during which time 142 were transplanted. Out of the transplanted patients, a total of 110 were eligible for inclusion. Sleep quality and depression were assessed with the validated questionnaires Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory (BDI), and data were collected during dialysis and after RTX. Based on PSQI scores, 59% were characterized as poor sleepers after RTX compared to 75% when in dialysis (P = 0.016). A total of 46% experienced a clinical relevant improvement in overall sleep quality, while 21% experienced a clinical relevant deterioration. In multivariable analyses, clinical meaningful change in sleep quality was not associated with either depressive symptoms assessed with BDI or other clinical variables. Sleep quality improved after RTX in nearly half of the patients, but poor sleep quality was prevalent in RTX patients. Therefore, sleep quality should routinely be assessed in RTX patients.

Is HRQOL in dialysis associated with patient survival or graft function after kidney transplantation?

BACKGROUND

Health related quality of life (HRQOL) is patient-reported, and an important treatment outcome for patients undergoing renal replacement therapy. Whether HRQOL in dialysis can affect mortality or graft survival after renal transplantation (RTX) is not determined. The aims of the present study were to investigate whether pretransplant HRQOL is associated with post-RTX patient survival or graft function, and to assess whether improvement in HRQOL from dialysis to RTX is associated with patient survival.

METHODS

In a longitudinal prospective study, HRQOL was measured in 142 prevalent dialysis patients (67 % males, mean age 51 ± 15.5 years) who subsequent underwent renal transplantation. HRQOL could be repeated in 110 transplant patients 41 (IQR 34-51) months after RTX using the self-administered Kidney Disease and Quality of Life Short Form (KDQOL-SF) measure. Kaplan-Meier plots were utilized for survival analyses, and linear regression models were used to address HRQOL and effect on graft function.

RESULTS

Follow-up time was 102 (IQR 97-108) months after RTX. Survival after RTX was higher in patients who perceived good physical function (PF) in dialysis compared to patients with poorer PF (p = 0.019). Low scores in the domain mental health measured in dialysis was associated with accelerated decline in graft function (p = 0.048). Improvements in the kidney-specific domains "symptoms" and "effect of kidney disease" in the trajectory from dialysis to RTX were associated with a survival benefit (p = 0.007 and p = 0.02, respectively).

CONCLUSION

HRQOL measured in dialysis patients was associated with survival and graft function after RTX. These findings may be useful in clinical pretransplant evaluations. Improvements in some of the kidney-specific HRQOL domains from dialysis to RTX were associated with lower mortality. Prospective and interventional studies are warranted.

Paediatric obesity and renal transplantation: current challenges and solutions

The increased incidence of obesity in the paediatric population poses significant challenges to renal transplantation. Whilst the body mass index appears to be widely used as a measure of obesity in adults, there are no standardised definitions in the paediatric population, making comparative analyses difficult. In the paediatric transplant population, obesity is associated with an increased incidence of surgical complications, diabetes, hyperlipidaemia and cardiovascular morbidity, leading to diminished graft function and impacting patient and graft survival. Management of obesity in renal transplantation requires multiple interventions starting with life-style and behavioural modification combined with medical and possibly surgical therapies, representing a unique challenge in the childhood setting. In this review we discuss the current challenges of obesity and potential solutions in the setting of paediatric transplantation.

Current practices in coronary artery disease evaluation of renal transplant candidates prior to renal transplantation

Cardiovascular disease is the leading cause of morbidity and mortality in renal transplant recipients and candidates awaiting transplant. Pre-transplant coronary artery disease evaluation can aid in determining transplant candidacy, identifying patients who may benefit from pre-operative cardiac intervention, and implementing measures to reduce perioperative and post-transplant cardiovascular events. However, the choice of investigations and approach in evaluation has yet to be well defined. This article aims to review the evidence for the use of non-invasive investigations and coronary angiography in prognostication, as well as the evidence for revascularization in reducing future cardiac events. The article will also summarize international recommendations and describe the local practice in coronary artery disease evaluation prior to transplant.

Depression, Anxiety, Resilience and Coping Pre and Post Kidney Transplantation - Initial Findings from the Psychiatric Impairments in Kidney Transplantation (PI-KT)-Study

PURPOSE

Depression/anxiety, impaired Health-Related Quality of Life (HRQoL) and coping and resilience structures, are associated with increased mortality/poor outcome in chronic kidney disease (CKD) patients before (CKD/pre-KT) and after kidney (CKD-T) transplantation. Less is known about prevalence rates of psychiatric symptoms and impaired HRQoL of non-transplanted compared with transplanted patients.

METHODS

In a cross-sectional study comparing 101 CKD/pre-KT patients with 151 cadaveric-transplanted (CKD-T) patients, we examined prevalence of depression/anxiety (HADS questionnaire) and coping, resilience and HRQoL (SF-12, Resilience-Scale and FKV-questionnaire).

RESULTS

The prevalence of both depressive and anxiety symptoms was not significantly different between different pre-/and CKD-T patient groups. In CKD-T no significant relations of coping strategies with kidney function were identified. Furthermore, the Resilience Scales for acceptance and competence did not suggest any differences between the CKD/pre-KT and CKD-T subgroup. In the CKD/pre-KT patients, significant correlations were identified between the acceptance subscale and partnership, as well as between the competence subscale and older age/partnership.

CONCLUSIONS

Both the CKD/pre-KT and CKD-T patients exhibited notable impairments in the HRQoL which which showed a comparable pattern of results. KT itself does not appear to be the main risk factor for the development of mental impairments.

Risk factors for cardiovascular events among Asian patients without pre-existing cardiovascular disease on the renal transplant wait list

Introduction:

For suitable end-stage renal failure (ESRF) patients, renal transplantation gives better long term survival and quality of life as compared to dialysis. Prior to entry into the renal transplant wait list, potential candidates are screened for the presence of cardiovascular disease. However, the waiting time on the transplant list is long, and interval screening for cardiac fitness for surgery is not well defined. We aim to study the risk factors for the development of a cardiovascular event (CVE) and the time interval from recruitment to onset of a CVE that resulted in their removal from the transplant wait list.

Methods:

A retrospective study of all patients registered under the cadaveric renal transplant waiting list in Singapore General Hospital (SGH) from 16^th April 1987 to 31^st October 2010. We identified patients who developed a CVE among this cohort. We compared the demographics and clinical characteristics of patients who experienced a CVE versus those who did not. Univariable and multivariable cox regression were performed to investigate the significant variables for the development of a CVE. The time to development of CVE was estimated using Kaplan Meier estimation and log-rank test was used to compare the time to CVE between those with diabetes mellitus and those without.

Results:

1265 patients were enrolled in this study. 273 patients dropped out of the wait list due to medical reasons or death, of which 38.8% were due to CVE. The mean and median time duration from recruitment into the waiting list to development of a CVE was 14.42 (95% CI 13.72 to 15.11) and 15.69 (95% CI 13.86 to 17.51) years respectively. For patients with diabetes mellitus, this was 8.22 (95% CI 6.30 to 10.14) and 8.16 (95% CI 4.95 to 11.36) years respectively. Factors associated with an increased risk of developing a CVE included male gender (adjusted HR 2.21, 95% CI 1.43 to 3.41, p<0.001), presence of diabetes mellitus (adjusted HR 5.13, 95% CI 2.85 to 9.24, p<0.001) and patients who were either not working or working part-time as compared to their full-time counterparts (adjusted HR 1.76, 95% CI 1.14 to 2.72, p=0.010). In addition, hazard ratio for CVE significantly increased with advancing age quartile (p<0.001 by log rank test for trend).

Conclusion:

A significant proportion of patients exited from the renal transplant wait list due to a CVE. Being male, age 37 years old or more, presence of diabetes mellitus and non-working or part-time workers as compared to full-time workers were found to increase the risk of developing a CVE during the wait period for transplantation. The presence of diabetes mellitus significantly shortened the time to development of a CVE.

Dream anxiety in renal transplant recipients

OBJECTIVE

Although low quality of sleep has been reported in kidney transplant patients with functioning allografts, there are no previous studies investigating the dreams of these patients. We aimed to investigate the differences in dream anxiety level between renal transplant patients and healthy control subjects. We also planned to compare depression and anxiety symptoms, sleep quality and sleepiness level between these two groups.

METHODS

Twenty-two living-donor renal transplant recipients followed at an outpatient nephrology clinic and 22 healthy controls were enrolled in this observational cross-sectional study. Sociodemographic Data Collection Form, and the Van Dream Anxiety Scale (VDAS), the Pittsburg Sleep Quality Index (PSQI), the Insomnia Severity Index (ISI), Beck Depression and Anxiety Inventories were used for the assessment of the necessary features. Hemoglobin (Hb), blood urea nitrogen (BUN), creatinine (Cr) and glucose levels were measured.

RESULTS

There were no significant differences between the groups in terms of dream anxiety (p = 0.45), depression (p = 0.76), sleep quality (p = 0.8), insomnia severity (p = 0.08) and Hb (p = 0.11) and glucose levels (p = 0.14). Although, BUN (p = 0.00) and creatinine (p = 0.00) levels differed significantly between the two groups, both parameters were found to be within their normal range.

CONCLUSIONS

In our study, chronic renal failure patients with a successful kidney transplant were found to be able to completely return to normal in terms of metabolic parameters, sleep quality and mood. Similar levels of dream anxiety are also consistent with these findings.

Readiness of wait-listed black patients to pursue live donor kidney transplant

CONTEXT

For adults with end-stage kidney disease, live donor kidney transplant (LDKT) has better outcomes than long-term dialysis and deceased donor kidney transplant. However, black patients receive LDKT at a much lower rate than adults of any other race or ethnicity.

OBJECTIVE

To examine the LDKT readiness stage of black patients on the transplant waiting list and its association with LDKT knowledge, concerns, and willingness.

DESIGN

Cross-sectional analysis of baseline data from a randomized controlled trial to improve knowledge and reduce concerns about LDKT.Patients and Setting-One hundred fifty-two black patients on the kidney transplant waiting list at a single transplant center in the northeastern United States.

MAIN OUTCOME MEASURES

LDKT readiness stage, knowledge, concerns, and willingness to talk to others about living donation.

RESULTS

Sixty percent of patients were not considering or not yet ready to pursue LDKT, and only 11% had taken action to talk to family members or friends about the possibility of living kidney donation. Patients in later stages of LDKT readiness (ie, who had talked to others about donation or were preparing to do so) had significantly more knowledge (P<.001), fewer concerns (P=.002), and more willingness (P=.001) to talk to others about living donation than those in earlier readiness stages.

CONCLUSIONS

The large percentage of black patients who are in the earlier stages of LDKT readiness may account for the low rate of LDKT in this patient population at our transplant center. Innovative and tailored LDKT educational strategies for black patients are needed to help reduce racial disparities in LDKT.

From dialysis to transplantation: a 5-year longitudinal study on self-reported quality of life

Background

Little is known how health related quality of life (HRQOL) change in the transition from dialysis to renal transplantation (RTX). Longitudinal data addressing the patient-related outcomes are scarce, and particularly data regarding kidney-specific HRQOL are lacking. Thus, the aim of the current study was to assess HRQOL in patients followed from dialysis to RTX. Furthermore, to compare HRQOL in RTX patients and the general population.

Methods

In a prospective study, HRQOL was measured in a cohort of 110 patients (median age 53.5 (IQR 39–62) years, GFR 54 (45–72) ml/min/1.73 m²) in dialysis and after RTX using the self-administered Kidney Disease and Quality of Life Short Form version 1.3 (KDQOL-SF). Generic HRQOL in the RTX patients was compared to that of the general population (n = 5903) using the SF-36. Clinical important change after RTX was defined as difference in HRQOL of SD/2.

Results

Follow-up time was 55 (IQR 50–59) months, and time after RTX was 41 (34–51) months. Four of nine domains in kidney-specific HRQOL improved after RTX, i.e. burden of kidney disease, effect of kidney disease, symptoms and work status. In SF-36, general health, vitality, social function and role physical improved after RTX, but none of the domains improved sufficiently to be regarded as clinically relevant change. There were highly significant differences in HRQOL between RTX patients and the general population after adjustment for age and gender for all items of SF-36 except for bodily pain and mental health.

Conclusions

HRQOL improved in the transition from dialysis to transplantation, but clinical relevant change was only obtained in the kidney specific domains. HRQOL was perceived considerably poorer in RTX patients than in the general population. Our observations point to the need of improving HRQOL even after RTX, and should encourage further longitudinal research and clinical attention during treatment shift.
