Depression in Kidney Transplant Recipients: Prevalence, Risk Factors, and Association With Functional Disabilities

Effect of Physical Function on Access to Repeat Kidney Transplantation

Background: The long-term success rate of kidney transplantation is disappointing, with repeat transplantation necessary for more than half of recipients. When a repeat kidney transplantation is needed, patients are often elderly and suffer from underlying advanced kidney disease, comorbidities, and adverse effects of immunosuppressants, leading to physical function limitations. Limited physical function is known to hinder access to an initial kidney transplantation, but there is no information about its impact on repeat transplantations. Objective: This study aimed to determine the effect of physical function on access to wait-listing for repeat transplantation. Methods: Data from the national registry was utilized to analyze 28,884 kidney transplant recipients. Physical function was assessed with Karnofsky scores, and patients were categorized into three strata: total assistance, some assistance, and no assistance. Logistic regression and multivariate Cox proportional hazard models were used to assess the impact of physical function on waiting list access and duration until wait-listing, respectively. Results: Patients with greater physical independence were more likely to be wait-listed for repeat kidney transplantation. Highly sensitized patients, those with diabetes, Black patients, and elderly individuals had a lower likelihood of access to wait-listing after kidney failure. Interestingly, those with limited physical function, provided they remained in the work-up process, experienced a relatively shorter duration to wait-listing after graft failure.Conclusions: These findings highlight the need to promote and support physical function throughout the kidney transplant journey to improve access to repeat transplantation and subsequent patient outcomes.

The Psychosocial Adjustment of Kidney Recipients in Canada's Kidney Paired Donation Program

Introduction: Kidney paired donation programs have been implemented globally. The involvement of at least 2 donors in these programs might exacerbate recipients' debt of gratitude and guilt, worries about the donor's health, and worries about graft failure documented by previous studies. However, there is an absence of research on the psychosocial implications of kidney paired donation. This study aimed to provide an in-depth examination of recipients' experience of kidney paired donation, with a focus on psychosocial adjustment. Methods/Approach: Individual interviews were conducted with 8 recipients who received a transplant through Canada's Kidney Paired Donation program. Data was analyzed using Interpretative Phenomenological Analysis. Findings: Four themes emerged: (a) an emotionally charged relationship with the known donor, (b) optimal distance regulation in the relationship with the anonymous donor, (c) kidney paired donation as a series of ups and downs, and (d) multilayered gratitude. Discussion: Findings are considered in relation to extant literature. Issues relevant to the transplant community's clinical and research efforts to provide kidney recipients responsive care are discussed.

Early estimated glomerular filtration rate and depression in kidney transplantation recipients: a longitudinal study

Depression is a common psychological problem in kidney transplantation (KT) recipients and affects long-term graft outcomes. Estimated glomerular filtration rate (eGFR) as a commonly used indicator of renal function plays a vital role in follow-up detection after KT. The aim of this study is to observe the change of early eGFR within 3 months after KT and to explore the correlation between eGFR and depression before and after transplantation. The Self-rating Depression Scale was used to evaluate depression. Among 135 patients with KT, 128 patients completed the longitudinal study. We used a one-way repeated-measures analysis of variance to analyze eGFR and a generalized estimating equation model to examine the relationship between depression and eGFR in KT recipients with pre-transplant and 30, 60, 90 days post-transplant. The mean eGFR of KT recipients at four time-points was 5.97 ± 4.83, 72.84 ± 26.06, 79.06 ± 26.45 and 81.79 ± 25.62, respectively. The results demonstrated that eGFR kept steady at 60 days and 90 days post-transplant; depression was significantly associated with eGFR. Earlier identification and treatment of depression in KT recipients may be essential to promote their recovery of early renal function.

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.

Association between fatigue and depressive symptoms among kidney transplantation recipients: The mediating role of rumination

AIMS

Depressive symptoms are common among kidney transplantation recipients. Previous studies have reported that fatigue and rumination are risk factors for depressive symptoms. To date, the underlying mechanisms of fatigue, rumination, and depressive symptoms among kidney transplantation recipients remain unclear. This study aimed to assess the prevalence of depressive symptoms and investigate whether rumination mediates the association between fatigue and depressive symptoms among kidney transplantation recipients.

DESIGN

Cross-sectional study.

METHODS

The study of 207 kidney transplantation recipients with an average age of 44.5 years was conducted from January 2017-July 2017. Sociodemographic and clinical characteristics, fatigue, rumination, and depressive symptoms data were collected. For the descriptive analysis, Pearson correlations and mediation analysis based on the PROCESS macro were used.

RESULTS

The prevalence of depressive symptoms among kidney transplantation recipients was 21.7%. Rumination mediated the association between fatigue and depressive symptoms and the indirect effect was 0.19 (95% confidence interval: 0.10-0.28).

CONCLUSION

Depressive symptoms were highly prevalent among kidney transplantation recipients. Rumination exerts a mediating role between fatigue and depressive symptoms.

IMPACT

This study alerts physicians and nurses for the importance of considering the mental health of these patients and contributes to the development of effective depression management interventions.

The World Health Organization Disability Assessment Schedule-2.0 (WHODAS 2.0) in a chronic pain population being considered for chronic opioid therapy

Purpose

To examine the validity of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) for the assessment of function in a community-based sample of patients with chronic pain conditions undergoing evaluation for chronic opioid therapy.

Patients and methods

One hundred nine of 124 patients were evaluated for a chronic opioid therapy program between December 1, 2014 and April 10, 2015, inclusive, at one community-based interdisciplinary pain management practice. Measures included: demographic data; the WHODAS 2.0; a modified version of the Roland Morris Disability Questionnaire (RMDQ-m); the Patient Health Questionnaire-9 item (PHQ-9); the Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R); the Current Opioid Misuse Measure (COMM), the Opioid Risk Tool (ORT); opioid dose. These data were collected as part of routine care, and this retrospective chart review study examined the data from this convenience sample, comparing the results of each assessment tool to the results of the WHODAS 2.0.

Results

Median score on the WHODAS 2.0 was 25.69 (IQR=16.01 to 35.28). WHODAS 2.0 score was significantly correlated with the RMDQ-m (r_s=0.69, p<0.001), the PHQ-9 (r_s=0.68, p<0.001), the COMM (r_s=0.52, p<0.001) and the SOAPP-R (r_s=0.51, p<0.001). There was no significant correlation between the WHODAS 2.0 and the ORT (r_s=0.14, p=0.12) or opioid dose (r_s=0.07, p=0.47).

Conclusions

The WHODAS 2.0 was significantly positively correlated with other measures, including measures of disability, risk of opioid misuse, and depression among patients being evaluated for chronic opioid therapy. The WHODAS 2.0 may be a useful measure of disability across a number of important domains when discussing expectations of both patients and providers at initiation of opioid therapy for chronic pain management. This assessment and discussion is crucial, particularly given the focus on function, rather than analgesia alone, when evaluating the effectiveness of opioid treatment.
