Challenges in posttransplantation care for kidney transplant recipients: A qualitative study highlighting gaps in psychological, social and exercise support. J Ren Care 2024. [PMID: 39049568 DOI: 10.1111/jorc.12507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 07/12/2024] [Accepted: 07/13/2024] [Indexed: 07/27/2024]
Abstract
BACKGROUND Kidney transplantation offers meaningful health improvements compared to dialysis, yet the quality of life and life expectancy of kidney transplant recipients still lag behind those of their healthy peers. Physical inactivity and poor physical fitness are prevalent among kidney transplant recipients, affecting overall life participation. OBJECTIVES To explore challenges hindering life participation for kidney transplant recipients and reveal facilitators and barriers to integrating rehabilitation into their daily lives. DESIGN An explorative study using a qualitative method. PARTICIPANTS Fourteen purposively selected kidney transplant recipients. APPROACH Semistructured, individual interviews were conducted posttransplantation. The following topics were covered: living with chronic kidney disease, pretransplantation challenges, posttransplantation recovery, engagement in various activities, including physical activity, and the need for supervised exercise rehabilitation programmes. Interviews were recorded and transcribed verbatim, and an inductive thematic analysis approach was used. FINDINGS Data saturation occurred after analysing 12 interviews, revealing two main themes: the impact on life participation and the impact on physical and mental functioning. Participants expressed the need for comprehensive posttransplant care, including mental health support, family education and guidance on returning to work. Structured support in managing physical fitness, tailored to individual preferences, was also recognised as important. CONCLUSIONS The study underscores the necessity for a biopsychosocial approach to posttransplant care that addresses the multifaceted challenges faced by kidney transplant recipients. A multidisciplinary approach, tailored support, education and individualised exercise programmes are crucial for enhancing their overall well-being and integrating rehabilitation into their daily lives, considering both physical and psychosocial aspects.

A multimodal aftercare intervention improves the outcome after kidney transplantation - results of the KTx360° aftercare program using claims data. EClinicalMedicine 2024; 73:102652. [PMID: 38841709 PMCID: PMC11152610 DOI: 10.1016/j.eclinm.2024.102652] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2024] [Revised: 04/26/2024] [Accepted: 05/03/2024] [Indexed: 06/07/2024] Open
Abstract
Background The after-care treatment project KTx360° aimed to reduce graft failure and mortality after kidney transplantation (KTx). Methods The study was conducted in the study centers Hannover, Erlangen and Hannoversch Muenden from May 2017 to October 2020 under the trial registration ISRCTN29416382. The program provided a multimodal aftercare program including specialized case management, telemedicine support, psychological and exercise assessments, and interventions. For the analysis of graft failure, which was defined as death, re-transplantation or start of long-term dialysis, we used longitudinal claims data from participating statutory health insurances (SHI) which enabled us to compare participants with controls. To balance covariate distributions between these nonrandomized groups we used propensity score methodology, in particular the inverse probability of treatment weighting (IPTW) approach. Findings In total, 930 adult participants were recruited at three different transplant centres in Germany, of whom 320 were incident (enrolled within the first year after KTx) and 610 prevalent (enrolled >1 year after KTx) patients. Due to differences in the availability of the claims data, the claims data of 411 participants and 418 controls could be used for the analyses. In the prevalent group we detected a significantly lower risk for graft failure in the study participants compared to the matched controls (HR = 0.13, 95% CI = 0.04-0.39, p = 0.005, n = 389 observations), whereas this difference could not be detected in the incident group (HR = 0.92, 95% CI = 0.54-1.56, p = 0.837, n = 440 observations). Interpretation Our findings suggest that a multimodal and multidisciplinary aftercare intervention can significantly improve outcome after KTx, specifically in patients later after KTx. For evaluation of effects on these outcome parameters in patients enrolled within the first year after transplantation longer observation times are necessary. Funding The study was funded by the Global Innovation fund of the Joint Federal Committee of the Federal Republic of Germany, grant number 01NVF16009.

Abstract
BACKGROUND Physical activity is a key factor in improvement of quality of life. This study aimed to assess the extent of physical activity in solid-organ transplant recipients. MATERIAL AND METHODS The study involved 106 patients, mostly kidney (64.15%) and liver (28.30%) recipients, observed in a Warsaw transplant center. The study group was dominated by women (56.6%), mean age 49.25±14.09 years, the time since transplantation ranged from 1 month to 28 years, with a mean of 93.9±71.83 months. Recipients were educated about physical activity in the immediate post-transplant period and during follow-up visits. The study was conducted in early 2021 and used the long form of the International Physical Activity Questionnaire (IPAQ) validated for Polish patients, consisting of the of 5 parts - physical activity, professional work, travel, housework, recreation, and time spent sitting - containing a total of 27 questions in the main part of the questionnaire and 7 questions in the introductory part determining the typicality of the last 7 days. RESULTS More than half (57.5%) of the transplant recipients reported high levels of physical activity. Patients reported the highest mean physical activity in job-related physical activity (P<0.001). Patients also had high scores for walking and moderate-intensity physical activity, while the lowest mean scores were for leisure-time physical activity, total vigorous-intensity physical activity, and housework-related activity. CONCLUSIONS When undertaking physical activity, patients turn to activities that do not involve intense effort, are less physically demanding, and do not result in high energy expenditure. Employed patients had higher PA levels in all domains.

Abstract
OBJECTIVE Medication non-adherence to immunosuppressants threatens allograft survival and function maintenance among solid organ transplant (SOT) recipients. This study aimed to investigate the prevalence of immunosuppressant medication non-adherence and associated factors during the COVID-19 reopening period among Chinese SOT recipients. DESIGN Cross-sectional study. SETTING South-central China. POPULATION Adult patients who received SOT with functioning graft. METHODS Sociodemographic questionnaire and scales to measure physical activity, depression and medication non-adherence were used to collect data. Logistic regression analysis was conducted to identify factors associated with medication non-adherence. Mediation and moderated mediation analyses were performed to examine the potential mechanisms influencing medication behaviour during the pandemic reopening period using SPSS PROCESS macro 4.3 software. RESULTS A total of 1121 participants were recruited and the prevalence of medication non-adherence was 36.3% in this study. Recipients who were men, had a higher monthly income, lived alone, had received transplantation for a minimum of 3 years, had received COVID-19 vaccination and experienced depressive symptoms exhibited an increased risk of non-adherence. Contrarily, those who engaged in high-intensity physical activity exhibited a decreased risk. Physical activity was negatively associated with medication non-adherence (r=-0.124, p<0.001) with depression fully mediating this relationship (B=-0.014, 95% CI: -0.032 to -0.003). COVID-19 vaccination significantly moderated the relationship between physical activity and depression (B=-0.303, 95% CI: -0.515 to -0.090). CONCLUSION This study investigated the prevalence of medication non-adherence among SOT recipients during the COVID-19 reopening period in China, its associated factors and a potential mechanism. Depression fully mediated the association between physical activity and medication non-adherence, and COVID-19 vaccination moderated the relationship between physical activity and depression. These findings provide some insights for managing medication behaviour when confronting public health emergencies. However, relationships displayed in the moderated mediation model should be tracked after returning to normal life and other potential relationships should be explored to deeply understand medication non-adherent behaviour.

Relationship Between Physical Activity and Estimated Glomerular Filtration Rate in Renal Transplant Recipients: A Cross-sectional Study Analyzing Isotemporal Substitution Model. J Ren Nutr 2023; 33:755-763. [PMID: 37302717 DOI: 10.1053/j.jrn.2023.05.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2022] [Revised: 05/17/2023] [Accepted: 05/27/2023] [Indexed: 06/13/2023] Open
Abstract
OBJECTIVES Successful renal transplantation reduces mortality rates. However, the decline in the estimated glomerular filtration rate (eGFR) after transplantation is strongly associated with premature mortality in renal transplant recipients (RTRs). Physical activity (PA) is a modifiable lifestyle factor with the potential to maintain or improve eGFR. However, the effects of the type or intensity of PA and sedentary behavior (SB) on eGFR in RTRs remain unclear. The purpose of this study was to clarify the association between accelerometry-measured PA and SB and eGFR in RTRs using isotemporal substitution (IS) analysis. METHODS A total of 82 renal transplant outpatients participated in this cross-sectional study, of which 65 (average age, 56.9 years; average time post-transplant, 83.0 months) were finally analyzed. All RTRs wore a triaxial accelerometer to measure PA for 7 consecutive days. The measured PA was classified based on intensity into light PA, moderate-to-vigorous PA (MVPA), and SB. The association of each type of PA with eGFR was examined using multi-regression analyses of single-factor, partition, and IS models. The IS model was applied to examine the estimated effects of substituting 30 minutes of SB with an equal amount of time of light PA or MVPA on eGFR. RESULTS The partition model showed that MVPA was an independent explanatory variable for eGFR (β = 5.503; P < .05), and the IS model identified that the substitution of time spent in SB with MVPA led to improvements in eGFR (β = 5.902; P < .05). CONCLUSIONS The present study suggests that MVPA has an independent and positive association with eGFR, and replacing 30 minutes of SB with MVPA after renal transplantation might lead to the maintenance or improvement of eGFR in RTRs.

Abstract
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.

Abstract
Despite continuous advances in surgical and immunosuppressive protocols, the long-term survival of transplanted kidneys is still far from being satisfactory. Antibody-mediated rejection, recurrent autoimmune diseases, and death with functioning graft are the most frequent causes of late-kidney allograft failure. However, in addition to these complications, a number of other non-immunologic events may impair the function of transplanted kidneys and directly or indirectly lead to their failure. In this narrative review, we will list and discuss the most important nonimmune causes of late death-censored kidney graft failure, including quality of the donated kidney, adherence to prescriptions, drug toxicities, arterial hypertension, dyslipidemia, new onset diabetes mellitus, hyperuricemia, and lifestyle of the renal transplant recipient. For each of these risk factors, we will report the etiopathogenesis and the potential consequences on graft function, keeping in mind that in many cases, two or more risk factors may negatively interact together.

Abstract
Background: Obesity may negatively impact clinical outcomes in kidney transplant (KT) recipients. Limited information is available on the prevalence of obesity in this population, and on the lifestyle habits associated with obesity. Methods: we conducted an online, anonymous survey to assess of the proportion of KT recipients with obesity, adherence to the Mediterranean diet (i.e., a dietary regimen with proven renal and cardiovascular outcomes) using the MEDI-Lite questionnaire, and level of physical activity using the International Physical Activity Questionnaire (IPAQ) short form among KT recipients. Results: 255 KT recipients participated. Median (25th−75th quartile) age was 56.0 (48.0; 62.0) years, 43.9% female, median BMI 23.9 (21.6; 26.5) kg/m2. The proportion of KT recipients with obesity was 9.8% (95% confidence interval, 6.4 to 14.1%). Adequate adherence to the Mediterranean diet (Medi-Lite score >9) was overall low (44.7%; 40.0 vs. 45.2% in those with or without obesity, respectively; p = 0.618). In participants with obesity the Medi-Lite score inversely correlated with BMI (R = −0.45; p < 0.025). Overall, 30.6% of participants had a low level of physical activity (44.0 vs. 29.1% of those with or without obesity, respectively; p = 0.125). The amount of energy expended walking was significantly lower among participants with obesity (462 (0.0; 1436) vs. 1056 (433; 2005) METs/week, p = 0.017). Conclusions: the burden of obesity among KT recipients is similar to that of the general population. Adherence to the Mediterranean diet was generally low, and nearly one-third of participants had a low level of physical activity. Building specialized multidisciplinary teams to manage obesity in KT recipients is urgently needed.

Abstract
BACKGROUND Cardiovascular disease (CVD) is a major cause of morbidity and mortality in kidney transplant recipients (KTRs). CVD risk scores underestimate risk in this population as CVD is driven by clustering of traditional and non-traditional risk factors, which lead to prognostic pathological changes in cardiovascular structure and function. While exercise may mitigate CVD in this population, evidence is limited, and physical activity levels and patient activation towards exercise and self-management are low. This pilot study will assess the feasibility of delivering a structured, home-based exercise intervention in a population of KTRs at increased cardiometabolic risk and evaluate the putative effects on cardiovascular structural and functional changes, cardiorespiratory fitness, quality of life, patient activation, healthcare utilisation and engagement with the prescribed exercise programme. METHODS AND ANALYSIS Fifty KTRs will be randomised 1:1 to: (1) the intervention; a 12week, home-based combined resistance and aerobic exercise intervention; or (2) the control; usual care. Intervention participants will have one introductory session for instruction and practice of the recommended exercises prior to receiving an exercise diary, dumbbells, resistance bands and access to instructional videos. The study will evaluate the feasibility of recruitment, randomisation, retention, assessment procedures and the intervention implementation. Outcomes, to be assessed prior to randomisation and postintervention, include: cardiac structure and function with stress perfusion cardiac MRI, cardiorespiratory fitness, physical function, blood biomarkers of cardiometabolic health, quality of life and patient activation. These data will be used to inform the power calculations for future definitive trials. ETHICS AND DISSEMINATION The protocol was reviewed and given favourable opinion by the East Midlands-Nottingham 2 Research Ethics Committee (reference: 19/EM/0209; 14 October 2019). Results will be published in peer-reviewed academic journals and will be disseminated to the patient and public community via social media, newsletter articles and presentations at conferences. TRIAL REGISTRATION NUMBER NCT04123951.

Abstract
In patients with chronic kidney disease, sedentary behavior is widely recognized as a significant risk factor for cardiovascular disease, diabetes, obesity, osteoporosis, cancer, and depression. Nevertheless, the real impact of physical inactivity on the health of kidney transplant (KT) recipients remains uncertain. Over the last decade, there has been a renewed interest in exploring the effects of regular physical exercise on transplant-related outcomes. There is now mounting evidence that physical activity may reduce the burden of cardiovascular risk factors, preserve allograft function, minimize immunosuppression requirement, and ameliorate the quality of life of KT recipients. Many positive feedbacks can be detected in the early stages of the interventions and with a minimal exercise load. Despite these encouraging results, the perceived role of physical activity in the management of KT candidates and recipients is often underrated. The majority of trials on exercise training are small, relatively short, and focused on surrogate outcomes. While waiting for larger studies with longer follow-up, these statistical limitations should not discourage patients and doctors from initiating exercise and progressively increasing intensity and duration. This narrative review summarizes current knowledge about the deleterious effects of physical inactivity after KT. The benefits of regular physical exercise are also outlined.
