Psychosocial and Clinical Associations of Fatigue Severity and Fatigue-Related Impairment in Kidney Transplant Recipients

Debilitating fatigue is common in people living with kidney disease and often persists after a kidney transplant. Current understanding of fatigue is centered around pathophysiological processes. Little is known about the role of cognitive and behavioral factors. The aim of this study was to evaluate the contribution of these factors to fatigue among kidney transplant recipients (KTRs). A cross-sectional study of 174 adult KTRs who completed online measures of fatigue, distress, illness perceptions, and cognitive and behavioral responses to fatigue. Sociodemographic and illness-related information was also collected. 63.2% of KTRs experienced clinically significant fatigue. Sociodemographic and clinical factors explained 16.1% and 31.2% of the variance in the fatigue severity and fatigue impairment, respectively, increasing by 28% and 26.8% after adding distress. In adjusted models, all the cognitive and behavioral factors except for illness perceptions were positively associated with increased fatigue-related impairment, but not severity. Embarrassment avoidance emerged as a key cognition. In conclusion, fatigue is common following kidney transplantation and associated with distress and cognitive and behavioral responses to symptoms, particularly embarrassment avoidance. Given the commonality and impact of fatigue in KTRs, treatment is a clinical need. Psychological interventions targeting distress and specific beliefs and behaviors related to fatigue may be beneficial.

The Cognitive and Behavioural Responses to Symptoms Questionnaire (CBRQ): Development, reliability and validity across several long-term conditions

OBJECTIVES

Cognitive and behavioural responses to symptoms can worsen or maintain the severity of symptoms across long-term conditions (LTCs). Although the Cognitive and Behavioural Responses Questionnaire (CBRQ) has been used in research, its original development and psychometric properties as a transdiagnostic measure have not been reported. Our aim was to evaluate the psychometric properties of the CBRQ and a recently proposed short version, across different LTCs.

DESIGN

Psychometric validation study.

METHODS

Confirmatory factor analysis (CFA) tested the factor structure of the CBRQ in two datasets from the CBRQ's original development; (chronic fatigue syndrome, N = 230; and multiple sclerosis, N = 221) and in additional groups: haemodialysis (N = 174), inflammatory bowel disease (N = 182) and chronic dizziness (N = 185). Scale reliability and construct validity were assessed. The factor structure of the shortened CBRQ (CBRQ-SF) was also assessed.

RESULTS

CFA revealed that a 7-or 8-factor structure had generally appropriate fit supporting the originally proposed 7 factors (Fear avoidance, Damage beliefs, Catastrophising, Embarrassment avoidance, Symptom focusing, All-or-nothing behaviour and Avoidance/Resting behaviour). Omega coefficients indicated satisfactory internal reliability. Correlations with related constructs suggested construct validity. The scale appeared sensitive to change. The CBRQ-SF also displayed good psychometric quality, with a better model fit than the CBRQ.

CONCLUSIONS

The CBRQ and the shortened version were shown to be reliable and valid at assessing a range of cognitive and behavioural responses to symptoms, highlighting the multi-symptom, transdiagnostic properties of this questionnaire. Further research is necessary to determine the test-retest reliability and sensitivity to change of the CBRQ and CBRQ-SF and a thorough evaluation of the content validity of the items.

The effect of intravenous iron supplementation on exercise capacity in iron-deficient but not anaemic patients with chronic kidney disease: study design and baseline data for a multicentre prospective double-blind randomised controlled trial

BACKGROUND

Many people living with chronic kidney disease (CKD) are iron deficient, even though they may not be anaemic. The Iron and Muscle study aims to evaluate whether iron supplementation reduces symptoms of fatigue, improves muscle metabolism, and leads to enhanced exercise capacity and physical function. We report here the trial design and baseline characteristics.

METHODS

This is a prospective, double-blind multicentre randomised controlled trial (RCT) including 75 non-dialysis stage 3-4 CKD patients with iron deficiency but without anaemia. Patients were randomly (1:1) assigned to either: i) intravenous iron therapy, or ii) placebo, with concurrent recruitment of eight CKD non-iron deficient participants and six healthy volunteers. The primary outcome of the study is the six-minute walk test (6MWT) distance between baseline and four-weeks. An additional exercise training programme for patients in both groups was initiated and completed between 4 and 12 weeks, to determine the effect of iron repletion compared to placebo treatment in the context of patients undertaking an exercise programme. Additional secondary outcomes include fatigue, physical function, muscle strength, muscle metabolism, quality of life, resting blood pressure, clinical chemistry, safety and harms associated with the iron therapy intervention and the exercise training intervention, and hospitalisations. All outcomes were conducted at baseline, 4, and 12 weeks, with a nested qualitative study, to investigate the experience of living with iron deficiency and intervention acceptability. The cohort have been recruited and baseline assessments undertaken.

RESULTS

Seventy-five individuals were recruited. 44% of the randomised cohort were male, the mean (SD) age was 58 (14) years, and 56% were White. Body mass index was 31 (7) kg/m²; serum ferritin was 59 (45) μg/L, transferrin saturation was 22 (10) %, and haemoglobin was 125 (12) g/L at randomisation for the whole group. Estimated glomerular filtration rate was 35 (12) mL/min/1.73 m² and the baseline 6MWT distance was 429 (174) m.

CONCLUSION

The results from this study will address a substantial knowledge gap in the effects of intravenous iron therapy, and offer potential clinical treatment options, to improve exercise capacity, physical function, fatigue, and muscle metabolism, for non-dialysis patients with CKD who are iron-deficient but not anaemic. It will also offer insight into the potential novel effects of an 8-week exercise training programme.

Experiences of a cognitive behavioural therapy (CBT) intervention for fatigue in patients receiving haemodialysis

BACKGROUND

A feasibility randomised-controlled trial found that a cognitive-behavioural therapy intervention for renal fatigue has the potential to reduce fatigue in patients receiving haemodialysis, but uptake was low.

OBJECTIVES

Nested in the randomised-controlled trial (RC) qualitative interviews were undertaken to understand the acceptability of renal fatigue, the facilitators of, and barriers to, engagement, and the psychosocial processes of change.

DESIGN

The trial included 24 participants at baseline. Semi-structured interviews were conducted with nine participants from the intervention arm (n = 12). Approach Interviews were carried out immediately following treatment (3 months post-randomisation). Data were analysed using inductive thematic analysis.

FINDINGS

Five main themes were formulated. The overarching theme was a sense of coherence (whether the illness, symptoms and treatment made sense to individuals), which appeared to be central to acceptability and engagement. Two themes captured the key barriers and facilitators to engagement, cognitive and illness/treatment burdens and collaboration with the therapist. Participants described changes related to their activity, thoughts and social identity/interactions, which shaped perceptions of change in fatigue. Lastly, participants discussed the optimal delivery of the intervention.

CONCLUSIONS

This study revealed the importance of patients' understanding of fatigue and acceptance of the treatment model for the acceptability of and engagement with a cognitive-behavioural therapy-based intervention for fatigue. Overall, there was an indication that such an intervention is acceptable to patients and the mechanisms of change align with the proposed biopsychosocial model of fatigue. However, it needs to be delivered in a way that is appealing and practical to patients, acknowledging the illness and treatment burdens.

Evaluation of the Effect of Lavender Aroma on Fatigue Among Hemodialysis Patients

Fatigue is a complication of hemodialysis (HD). We examined the effect of aromatherapy on fatigue in 62 HD patients. Data were collected using a questionnaire and the Piper Fatigue Scale. It was found that fatigue decreased in the intervention group (P < .05). Lavender aromatherapy is useful in reducing fatigue.

Fatigue Is Not Associated with Phase Angle in Hemodialysis Patients

PURPOSE

The aim of this study was to investigate the association between fatigue and phase angle (PA) in patients with chronic kidney disease (CKD) on hemodialysis (HD).

METHODS

A cross-sectional study with older patients than 18 years diagnosed with CKD undergoing HD. From 160 (58.36±15.05 years) patients, (n=96; 60%) are men. Body mass and height were assessed using a portable scale and stadiometer, followed by body mass index (BMI) calculus. The bioimpedance electrical analysis was performed using the Bodystat QuadScan 4000. The sample size was dichotomized in two groups, using the median of our sample, either normal when PA ≥5.4º, or low when the PA <5.4º. The Chalder fatigue questionnaire was used the assess the fatigue. The multiple regression was applied to assess the association between fatigue questionnaire and PA.

RESULTS

Were considered normal PA≥5.4º (n=78, 48.8%) and low PA<5.4º (n=82, 51.2%). The patients of the PA<5.4º group are older compared to the PA≥5.4º group (63.1±15.1 vs. 53.3±13.4 years, p<0.001). There was no association between PA and fatigue score in the crude model (OR: 1.02, 95%CI: 0.96-1.08, p=0.47) and after confounding variables (OR: 1.03, CI: 0.95-1.12, p=0.43).

CONCLUSIONS

In HD patients, we found that patients with lower PA values are older. In addition, we did not find association between fatigue and PA.

Patient-reported outcome measures in hemodialysis patients: results of the first multicenter cross-sectional ePROMs study in France

Background

Kidney failure with replacement therapy and hemodialysis are associated with a decrease in quality of life (QOL). Self-reported QOL symptoms are not always prioritized by the medical team, potentially leading to conflicting priorities with patients. Electronic patient-reported outcome measures (ePROMs) allow physicians to better identify these symptoms. The objective was to describe the prevalence of symptoms self-reported by hemodialysis (HD) patients.

Methods

A multicenter cross-sectional study was conducted in three HD centers. Patients were included if they were 18 years old or over treated with HD for at least 3 months in a center. Data were collected by the patient via a self-administered ePROMs questionnaire. Data included patient characteristics, post-dialysis fatigue and intensity, recovery time after a session, perceived stress, impaired sleep the day before the dialysis session, current state of health and the change from the past year. A multivariate analysis was conducted to identify relations between symptoms.

Results

In total, we included 173 patients with a mean age of 66.2 years, a mean ± SD hemodialysis duration of 48.9 ± 58.02 months. The prevalence of fatigue was 72%. 66% had a high level of stress (level B or C). Recovery time was more than 6 h after a HD session for 25% of patients and 78% declared they had a better or unchanged health status than the previous year. Sleep disturbance was associated with cardiovascular comorbidities (OR 5.08 [95% CI, 1.56 to 16.59], p = 0.007).

Conclusions

Fatigue and stress were the main symptoms reported by HD patients. The patient’s care teams should better consider these symptoms.

A Systematic Review of Potentially Effective Nonpharmacological Interventions for Reducing Fatigue among Iranian Patients Who Receive Hemodialysis

BACKGROUND AND PURPOSE

Fatigue control in hemodialysis (HD) patients requires a multidisciplinary approach. This study aimed to comprehensively review the available research literature regarding the nonpharmacological interventions used for reducing fatigue among Iranian HD patients.

METHODS

In this systematic review, an extensive search of the literature was conducted on PubMed, Web of Science, and Scopus databases, using the keywords related to the purpose. Also, the Persian equivalent of these keywords was searched in Iranian databases, such as Iranmedex and Scientific Information Database (SID) from the inception to June 16, 2020.

RESULTS

Of 2,761 articles, 25 studies were included in the review. Among a total of 1,748 Iranian HD patients with a mean age of 54.17 (SD = 12.27) years, 61.38% were male. Interventions such as educational-based programs (n = 5), nutrition-based programs (n = 2), massage therapy (n = 3), exercise-based programs (n = 4), relaxation technique (n = 3), combination of relaxation technique and inhalation aromatherapy (n = 1), energy therapy (reflexology and acupressure) (n = 3), and mind-guided imagery (n = 1) were effective in reducing fatigue in Iranian HD patients.

DISCUSSION/CONCLUSION

These simple, low-cost, and practical interventions can be used for the reduction of fatigue among HD patients by nurses. However, future well-designed studies are recommended to confirm the efficacy of these and other potentially effective interventions for reducing fatigue in HD patients.

Feasibility Trial of Cognitive Behavioral Therapy for Fatigue in Hemodialysis (BReF Intervention)

CONTEXT

Fatigue affects at least half of patients who are on hemodialysis (HD) with considerable repercussions on their functioning, quality of life, and clinical outcomes.

OBJECTIVES

This study assessed the feasibility, acceptability, and potential benefits of a cognitive behavioral therapy intervention for renal fatigue (BReF intervention).

METHODS

This was a feasibility randomized controlled trial of the BReF intervention vs. waiting-list control. Outcomes included recruitment, retention, and adherence rates. Exploratory estimates of treatment effect were computed. The statistician was blinded to allocation.

RESULTS

Twenty-four prevalent HD patients experiencing clinical levels of fatigue were individually randomized (1:1) to BReF (N = 12) or waiting-list control arms (N = 12). Fifty-three (16.6%; 95% CI = 12.7-21.1) of 320 patients approached consented and completed the screening questionnaire. It was necessary to approach 13 patients for screening for every one patient randomized. The rate of retention at follow-up was 75% (95% CI = 53.29-90.23). Moderate to large treatment effects were observed in favor of BReF on fatigue severity, fatigue-related functional impairment, depression, and anxiety (standardized mean difference [SMD]_g = 0.81; SMD_g = 0.93; SMD_g = 0.38; SMD_g = 0.42, respectively) but not sleep quality (SMD_g = -0.31). No trial adverse events occurred.

CONCLUSION

There was promising evidence in support of the need and benefits of a cognitive behavioral therapy-based intervention for fatigue in HD. However, uptake was low, possibly as a result of an already high treatment burden in this setting. Considerations on the context of delivery are necessary before pursuing a definitive trial.

A nonrandomised pilot study to examine the feasibility and acceptability of reflexology in patients undergoing hospital-based haemodialysis (solitude study)

BACKGROUND

Patients with end-stage kidney disease, receiving haemodialysis can experience complications-hypotension, headache, muscle cramp, chest pain, nausea and vomiting. Patients who experience all or some of these symptoms will often report reduced health-related quality of life (HRQOL) and poor sleep quality, which may lead to increased morbidity and mortality.

OBJECTIVE

The objective of this pilot study is to evaluate the feasibility of a larger randomised controlled trial to determine the effect of foot reflexology on a cohort of patients undergoing hospital-based haemodialysis.

DESIGN

A nonrandomised pilot study using a multimethod approach.

PARTICIPANTS

Twenty patients undergoing hospital-based haemodialysis treatment.

MEASUREMENTS

HRQOL and quality of sleep were measured using the SF-12 Health Survey and the Pittsburgh Sleep Quality Index (PSQI). Semi-structured interviews were completed with 10 patients, exploring their experiences, opinions and perceptions of the intervention.

RESULTS

There was an increase in the mean scores examining the total physical health and mental health components of the SF-12. All corresponding p values were statistically significant following the intervention. The mean total sleep score postintervention signified positive changes in sleep quality, with the corresponding p values being statistically significant. The study established the feasibility of the intervention and the benefits for patients undergoing haemodialysis.

CONCLUSION

This pilot study demonstrated the possibility of recruiting and retaining patients undergoing haemodialysis to a reflexology study. The study did not impact the haemodialysis routine and was positively received. The intervention showed statistically significant improvements in patients' HRQOL and sleep quality.

Fatigue, anxiety, depression and sleep quality in patients undergoing haemodialysis

OBJECTIVE

Patients undergoing haemodialysis may experience troubling symptoms such as fatigue, anxiety, depression and sleep quality, which may affect their quality of life. The main objective of this study is to determine the prevalence of fatigue, anxiety, depression and sleep quality among patients receiving haemodialysis during the coronavirus disease 2019 (COVID-19) pandemic, and to explore the contributing predictors.

METHODS

A cross-sectional and descriptive correlational design using Qualtrics software was performed. Data were collected using the Functional Assessment of Cancer Therapy-Fatigue (FACT-F), the Hospital Anxiety and Depression Scale (HADS) and the Pittsburgh Sleep Quality Index (PSQI). Logistic regression analyses were used to explore the predictors that were associated with fatigue, anxiety, depression and sleep quality.

RESULTS

Of the 123 patients undergoing haemodialysis who participated, 53.7% (n = 66) reported fatigue, 43.9% (n = 54) reported anxiety, 33.3% (n = 41) reported depression and 56.9% (n = 70) reported poor sleep. Fatigue, anxiety and sleep quality (P < .05) were significantly associated with being female, and whether family members or relatives were suspected or confirmed with COVID-19. Logistic regression showed that being within the age group 31-40, having a secondary education level, anxiety, depression and sleep quality were the main predictors affecting the fatigue group.

CONCLUSION

Fatigue, anxiety, depression and sleep quality are significant problems for patients receiving haemodialysis during the COVID-19 pandemic. Appropriate interventions to monitor and reduce fatigue, psychological problems and sleep quality amongst these patients are needed. This can help to strengthen preparations for responding to possible future outbreaks or pandemics of infectious diseases for patients receiving haemodialysis.

Exercise intolerance in kidney diseases: physiological contributors and therapeutic strategies

Exertional fatigue, defined as the overwhelming and debilitating sense of sustained exhaustion that impacts the ability to perform activities of daily living, is highly prevalent in chronic kidney disease (CKD) and end-stage renal disease (ESRD). Subjective reports of exertional fatigue are paralleled by objective measurements of exercise intolerance throughout the spectrum of the disease. The prevalence of exercise intolerance is clinically noteworthy, as it leads to increased frailty, worsened quality of life, and an increased risk of mortality. The physiological underpinnings of exercise intolerance are multifaceted and still not fully understood. This review aims to provide a comprehensive outline of the potential physiological contributors, both central and peripheral, to kidney disease-related exercise intolerance and highlight current and prospective interventions to target this symptom. In this review, the CKD-related metabolic derangements, cardiac and pulmonary dysfunction, altered physiological responses to oxygen consumption, vascular derangements, and sarcopenia are discussed in the context of exercise intolerance. Lifestyle interventions to improve exertional fatigue, such as aerobic and resistance exercise training, are discussed, and the lack of dietary interventions to improve exercise tolerance is highlighted. Current and prospective pharmaceutical and nutraceutical strategies to improve exertional fatigue are also broached. An extensive understanding of the pathophysiological mechanisms of exercise intolerance will allow for the development of more targeted therapeutic approached to improve exertional fatigue and health-related quality of life in CKD and ESRD.

Protocolized exercise improves frailty parameters and lower extremity impairment: A promising prehabilitation strategy for kidney transplant candidates

BACKGROUND

Frailty and decreased functional status are risk factors for adverse kidney transplant (KT) outcomes. Our objective was to examine the efficacy of an exercise intervention on frailty and decreased functional status in a cohort of patients with advanced chronic kidney disease (CKD).

METHODS

We conducted a prospective study involving 21 adults with ≥stage 4 CKD who were (a) frail or pre-frail by Fried phenotype and/or (b) had lower extremity impairment [short physical performance battery score ≤10]. The intervention consisted of two supervised outpatient exercise sessions per week for 8 weeks.

RESULTS

Among our cohort, median participant age was 62 years (interquartile range, 53-67) and 85.7% had been evaluated for KT. Following the study, participants reported satisfaction with the intervention and multiple frailty parameters improved significantly, including fatigue, physical activity, walking time, and grip strength. Lower extremity impairment also improved (90.5%-61.9%, P = .03). No study-related adverse events occurred.

CONCLUSIONS

Preliminary data from this study suggest that a supervised, outpatient exercise intervention is safe, acceptable, feasible, and associated with improved frailty parameters, and lower extremity function, in patients with advanced CKD. Further studies are needed to confirm these findings and determine whether this prehabilitation strategy improves KT outcomes.

A prospective study of fatigue trajectories among in-centre haemodialysis patients

Objectives

Fatigue is common and debilitating among dialysis patients. The aim of this study was to understand the longitudinal trajectory of fatigue and consider sociodemographic, clinical, and psychological factors that are related to variation in fatigue levels over time.

Design

A prospective study of fatigue with yearly assessments over 3 years among prevalent in‐centre haemodialysis (HD) patients.

Methods

Fatigue severity was measured using the Chalder Fatigue Questionnaire and fatigue‐related functional impairment using the Work and Social Adjustment Scale. The trajectories of fatigue outcomes were examined using piecewise growth models, using length of time on dialysis as time. Sociodemographic, clinical, and psychological predictors of fatigue were assessed using linear growth models, using follow‐up time.

Results

One hundred and seventy‐four prevalent HD patients completed baseline measures, 118 at 12 months, 84 at 24 months, and 66 at 36 months. Fatigue severity scores decreased by 0.15 each year. Fatigue‐related functional impairment increased by 1.17 each year. In adjusted linear growth models, non‐white ethnicity was a significant predictor of lower initial fatigue severity (B = −2.95, 95% CI −5.51 to −0.40) and a greater reduction in fatigue severity of 1.60 each year (95% CI 0.35–2.36). A one‐point increase in damage beliefs was associated with a 0.36 increase in fatigue‐related functional impairment each year (95% CI −0.61 to −0.01).

Conclusion

Damage beliefs predicted an increase in fatigue‐related functional impairment over time. However, the data strongly suggested that fatigue outcomes vary by length of time on dialysis.

The holistic management of fatigue within palliative care

BACKGROUND

Fatigue is a common symptom experienced by people with cancer and other long-term, non-malignant conditions. It can be disease-related or caused by treatments such as chemotherapy or radiotherapy. Patients frequently report this as a distressing symptom and, while some international guidelines for its management exist, evidence suggests that these are not always implemented.

METHOD

This article reviews the evidence basis for fatigue management, looking at exercise, education, psychological interventions, complementary therapies and pharmacological therapy, and finds that a one-size fits all approach to fatigue management is unrealistic.

FINDINGS

Research appears to support different interventions at various points in the disease trajectory and this is of importance for service design as palliative care is increasingly introduced earlier in the patient's pathway.

CONCLUSION

Although the body of research is growing, management of fatigue caused by non-malignant conditions remains poorly evidenced, making comprehensive recommendations for these patient groups even more challenging.
