Fatigue as experienced by patients with rheumatoid arthritis (RA): A qualitative study

Factors Affecting Pain Intensity Among Korean Women With Rheumatoid Arthritis: A Cross-Sectional Analysis

This cross-sectional study investigated the factors affecting pain intensity among Korean women with rheumatoid arthritis (RA) (n = 246). Data included pain site and intensity, physical function, fatigue, medication attitudes, and learned helplessness (LH) from patient self-report, and Disease Activity Score 28 (DAS28) from chart review. The overall pain intensity was 3.59 out of 10, with a median of 3. The mean number of painful joints was 8.4, with the most commonly reported painful joint groups being the fingers, wrists, and knees. Higher DAS28, impaired physical function, eight or more painful joints, higher levels of fatigue, and higher levels of LH were significantly associated with pain intensity. Our results suggest that pain in women with RA is closely associated with cognitive or psychological variables such as fatigue and LH in addition to inflammation itself. For improved pain management, patients with RA should receive regular counseling to address their feelings of LH and fatigue.

Exploring cognitive overload in adults with visual impairment: The association between concentration and fatigue

SIGNIFICANCE

This research contributes to the concept of cognitive overload and the association between concentration and fatigue in individuals with visual impairment (VI). Gaining more insight into these and other factors explaining cognitive overload is essential for a better understanding, prevention, and treatment of fatigue severity in individuals with VI.

PURPOSE

Individuals with VI need to use additional cognitive resources to compensate for their loss of vision. These cognitive demands include increased concentration, which may put an extra burden on energy levels. This study aimed to expand upon previous research on the concept of cognitive overload by exploring the relationship between concentration and fatigue severity in individuals with VI.

METHODS

A cross-sectional study was conducted based on data from the eligibility screening of the E-nergEYEze trial (n = 213). Concentration problems were measured with the Checklist of Individual Strengths subscale Concentration, and fatigue severity was measured with the Checklist of Individual Strengths subscale Fatigue Severity. Linear regression analyses were performed to investigate the association between concentration problems and fatigue severity. Potential effect modifiers (i.e., sociodemographic and vision-related characteristics) were considered, and associations were corrected for confounding.

RESULTS

Concentration problems were directly and positively associated with fatigue severity ( β = 0.47; R2 = 0.10; 95% confidence interval, 0.28 to 0.66; adjusted model: β = 0.52; R2 = 0.16; 95% confidence interval, 0.32 to 0.72). No relevant effect modifiers were identified. However, other factors that were not included in this study were involved in this association.

CONCLUSIONS

This study contributes to understanding the cognitive overload as experienced by adults with VI and highlights the importance of the association of concentration problems, as a reflection of the cognitive burden and perceived fatigue. It is recommended to identify and address concentration difficulties through suitable awareness and treatment strategies to prevent and reduce severe fatigue in this population.

Why does malaise/fatigue occur? Underlying mechanisms and potential relevance to treatments in rheumatoid arthritis

INTRODUCTION

Fatigue and malaise are commonly associated with a wide range of medical conditions, including rheumatoid arthritis (RA). Evidence suggests that fatigue and malaise can be overwhelming for patients, yet these symptoms remain inadequately-managed, largely due to an incomplete elucidation of the underlying causes.

AREAS COVERED

In this assessment of the published literature relating to the pathogenesis of fatigue or malaise in chronic conditions, four key mechanistic themes were identified. Each theme (inflammation, hypothalamic-pituitary-adrenal axis, dysautonomia, and monoamines) is discussed, as well as the complex network of interconnections between themes which suggests a key role for inflammatory cytokines in the development and persistence of fatigue.

EXPERT OPINION

Fatigue is multifaceted, poorly defined, and imperfectly comprehended. Moreover, the cause and severity of fatigue may change over time, as a consequence of the natural disease course or pharmacologic treatment. This detailed synthesis of available evidence permits us to identify avenues for current treatment optimization and future research, to improve the management of fatigue and malaise in RA. Within the development pipeline, several new anti-inflammatory therapies are currently under investigation, and we anticipate that the next five years will herald much-needed progress to reduce the debilitating nature of fatigue in patients with RA.

Baseline predictors of fatigue and persistent fatigue in rheumatoid arthritis: A longitudinal observational study

OBJECTIVES

To determine factors associated with fatigue in patients with rheumatoid arthritis (RA), and to identify baseline predictors of persistent fatigue at 12 months of follow-up.

METHODS

We enroled patients with RA fulfiling the 2010 American College of Rheumatology/European League Against Rheumatism criteria. Fatigue was assessed using the Arabic version of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). Using univariate and multivariate analyses, we examined baseline variables associated with fatigue and persistent fatigue (if the FACIT-F score was less than 40 at baseline and 12 months of follow-up).

RESULTS

We included 100 RA patients of whom 83% reported fatigue. At baseline, the FACIT-F score was significantly associated with older age (p = 0.007), pain (p < 0.001), global patient assessment (GPA) (p < 0.001), tender joint count (TJC) (p < 0.001), swollen joint count (p = 0.003), erythrocyte sedimentation rate (ESR) (p < 0.001), disease activity score (DAS28 ESR) (p < 0.001), and health assessment questionnaire (HAQ) (p < 0.001). At 12 months of follow-up, the percentage of patients who reported persistent fatigue was 60%. The FACIT-F score was significantly associated with age (p = 0.015), symptom duration (p = 0.002), pain (p < 0.001), GPA (p < 0.001), TJC (p < 0.001), C-Reactive Protein (p = 0.007), ESR (p = 0.009), DAS28 ESR (p < 0.001), and HAQ (p < 0.001). Pain was an independent baseline predictor of persistent fatigue (OR = 0.969 (95% CI [0.951-0.988]), p = 0.002).

CONCLUSIONS

Fatigue is a frequent symptom in RA. Pain, GPA, disease activity and disability were associated with fatigue and persistent fatigue. Baseline pain was the only independent predictor of persistent fatigue.

Testing the effectiveness of a Fatigue and Activity Management Education for Work (FAME-W) intervention for individuals with inflammatory arthritis: Study protocol for a randomized control trial

BACKGROUND

A work-focused fatigue management intervention, Fatigue and Activity Management Education for Work (FAME-W) programme was developed for individuals with inflammatory arthritis (IA) to manage fatigue in order to maintain demands of their work activities and tasks. This paper presents the protocol for a randomized control trial that will test the effectiveness and acceptability of FAME-W in improving work performance.

METHODS

This protocol presents a multisite randomized control trial and mixed methods process evaluation. Eligible participants will be aged 18-65 years with a diagnosis of inflammatory arthritis and will be in paid employment. The primary outcome of the study will be Work Role Functioning (WRF) questionnaire, and the secondary outcomes will be fatigue, mood, health-related quality of life (HRQOL) and pain. Data will be collected immediately pre- and post-intervention and at 3 months of follow-up. The process evaluation will consist of focus groups and individual interviews to explore participants' experiences of FAME-W. Occupational therapists delivering the programme will complete a facilitator log to assess the fidelity and quality of intervention implementations. Facilitators will participate in individual interviews to explore intervention delivery and acceptability.

RESULTS

Results will be expected to show that FAME-W will improve work performance by helping participants gain self-management strategies around managing fatigue and other symptoms related to fatigue.

CONCLUSION

It is hoped that FAME-W will be an effective and acceptable intervention for individuals with IA in improving work performance by helping them manage their symptoms.

Testing the feasibility and acceptability of an online 'Fatigue and Activity Management Education for Work (FAME-W) programme' for individuals with inflammatory arthritis

INTRODUCTION

Fatigue and Activity Management Education for Work (FAME-W) is a four-week, occupational therapy led programme focussing on fatigue management strategies. FAME-W was designed to be delivered in person; however, due to COVID-19 pandemic it was modified to be an online group-based self-management intervention. The purpose of this study was to test the feasibility and acceptability of the online delivery format of FAME-W.

METHODS

This was a mixed methods study. Participants were randomly allocated to intervention or control group. Participants in the intervention group received a four-week online FAME-W. The control group participants received a FAME-W handbook. Participants were required to complete questionnaires on work presenteeism, fatigue, mood, Health Related Quality of Life and pain at baseline, and 3 months post-intervention. Participants in the intervention group attended a focus group immediately following the completion of the programme and the control group participated in individual interviews.

RESULTS

Seven of ten individuals recruited participated in the study. Majority of participants had Rheumatoid Arthritis and were working full-time. The mean age of intervention participants was 53 ± 10.4 and 56.5 ± 3.7 for the controls. All participants in the intervention group had 100% attendance, completed all study measures and activities. Participants had positive comments about the programme format, content, and delivery. Improvements were observed in most measures at follow up.

CONCLUSION

Results suggest that an online programme to improve work ability was feasible and acceptable to individuals with inflammatory arthritis. The online delivery format was favoured over attending a centre-based programme. The findings support a definitive intervention trial of online FAME-W.

Severity and determinants of psychosocial comorbidities in granulomatosis with polyangiitis and their impact on quality of life

Depression, anxiety, sleep disturbances, and fatigue are inadequately addressed comorbidities in granulomatosis with polyangiitis (GPA). We determined the prevalence, severity, determinants, and the impact of these comorbidities on quality-of-life (QoL) in GPA. This observational study included adult GPA patients; patients with RA and lupus were included as comparators. Patient Health Questionnaire-9 for depression, Generalized Anxiety Disorder 7-item scale for anxiety, Epworth Sleepiness Scale for sleep disturbances, and Fatigue Severity Scale for fatigue were administered prospectively to estimate prevalence and severity. QoL and disability were estimated using PROMIS-HAQ, HAQ-health and HAQ-pain. Correlations among these parameters were assessed. Stepwise regression analyses were performed to identify determinants of depression, anxiety, excessive sleepiness, and fatigue. One hundred eighty-one patients-62 GPA [mean age 43 (13) years], 57 RA and 62 SLE- were included. The prevalence of depression (47%), excessive sleepiness (21%), and fatigue (39%) in GPA were comparable to RA and lupus; anxiety was less prevalent (29% versus 46% and 53%, p = 0.02). Severity was mostly mild-moderate. Younger age [OR = 0.93 (0.89-0.98)], higher BMI [OR = 1.2 (1.0-1.4)], and greater disease damage [OR = 2.0 (1.3-3.3)] independently predicted presence of depression. Higher BMI [OR = 1.3 (1.1-1.5)] and concomitant FMS [OR = 80.9 (5.1-1289.2)] were independently associated with excessive sleepiness. No association with disease activity, duration, or gender was seen. GPA patients with depression, anxiety, excessive sleepiness, and fatigue had worse PROMIS-HAQ, HAQ-pain, and HAQ-health. In conclusion, depression, anxiety, sleep disturbances, and fatigue are common in GPA. Although their severity is mostly mild-moderate, they impair QoL significantly. Potentially modifiable determinants that can form targets for future interventions have been identified.

The impact of Inflammatory Bowel Disease related fatigue on Health-Related Quality of Life: a qualitative semi-structured interview study

Background

Fatigue is a frequently reported symptom of Inflammatory Bowel Disease (IBD), having a negative impact on Health-Related Quality of Life (HRQoL). Patients' experiences of this have not been researched in IBD.

Methods

Semi-structured interviews were conducted with adults with Crohn's Disease from out-patient clinics in the United Kingdom. Interviews were audio-recorded and transcribed verbatim, then analysed using thematic analysis.

Results

Fourteen participant interviews were conducted. Three key themes were identified: 1) 'The new normal' established through adaptation and acceptance; 2) 'Energy as a resource' describing attempts to better manage fatigue through planning and prioritising tasks; 3) 'Keeping healthy' encompasses participants' beliefs that 'good health' allows better management of fatigue.

Conclusion

Participants establish a 'new' normality, through maintaining the same or similar level of employment/education activities. However, this is often at the expense of social activities. Further research is required to explore patient led self-management interventions in IBD fatigue.

Remote sampling of biomarkers of inflammation with linked patient generated health data in patients with rheumatic and musculoskeletal diseases: an Ecological Momentary Assessment feasibility study

Background

People with rheumatic diseases experience troublesome fluctuations in fatigue. Debated causes include pain, mood and inflammation. To determine the relationships between these potential causes, serial assessments are required but are methodologically challenging. This mobile health (mHealth) study explored the viability of using a smartphone app to collect patient-reported symptoms with contemporaneous Dried Blood Spot Sampling (DBSS) for inflammation.

Methods

Over 30 days, thirty-eight participants (12 RA, 13 OA, and 13 FM) used uMotif, a smartphone app, to report fatigue, pain and mood, on 5-point ordinal scales, twice daily. Daily DBSS, from which C-reactive Protein (CRP) values were extracted, were completed on days 1–7, 14 and 30. Participant engagement was determined based on frequency of data entry and ability to calculate within- and between-day symptom changes. DBSS feasibility and engagement was determined based on the proportion of samples returned and usable for extraction, and the number of days between which between-day changes in CRP which could be calculated (days 1–7).

Results

Fatigue was reported at least once on 1085/1140 days (95.2%). Approximately 65% of within- and between-day fatigue changes could be calculated. Rates were similar for pain and mood. A total of 287/342 (83.9%) DBSS, were returned, and all samples were viable for CRP extraction. Fatigue, pain and mood varied considerably, but clinically meaningful (≥ 5 mg/L) CRP changes were uncommon.

Conclusions

Embedding DBSS in mHealth studies will enable researchers to obtain serial symptom assessments with matched biological samples. This provides exciting opportunities to address hitherto unanswerable questions, such as elucidating the mechanisms of fatigue fluctuations.

The Assessment of Fatigue in Rheumatoid Arthritis Patients and Its Impact on Their Quality of Life

Introduction: Rheumatoid arthritis (RA) is a common autoimmune illness that manifests mostly as chronic, symmetric, and progressive polyarthritis with a global frequency of 0.3−1.0%. RA is a disease that affects people all over the world. In India, the prevalence is estimated to be 0.7%, with around 10 million persons suffering from RA. Most people with rheumatoid arthritis experience fatigue on most days, with over 70% experiencing symptoms similar to chronic fatigue syndrome. Patients rate fatigue as a top priority and believe this unmanageable symptom is ignored by clinicians; a systematic review shows the biological agents for RA inflammation have only a small effect on fatigue. Fatigue predicts and reduces the quality of life, and it is as difficult to cope with as pain. Physicians have traditionally concentrated on the inflammatory aspects of the illness (e.g., synovitis), whereas RA patients have prioritized pain, exhaustion, sleep difficulties, and other quality-of-life issues. Aims and Objectives: The basic aim of the study was to access the incidence of fatigue in rheumatoid arthritis and evaluate its impact on the quality of life in these patients using the MAF scale (multidimensional assessment of fatigue) after prior permission for the first time in an Asian population. Results: A total of 140 subjects and 100 controls were included in the study. Age was closely matched between the study subjects and controls. Among study subjects with the disease, 94 (67%) had a disease duration ≤ 5 years, 26 (19%) had a disease duration between 6−10 years, 10 (7%) had a duration of 11−15 years and 10 (7%) had >10 years disease duration. Among the sample, 31 (25%) study subjects had a DAS score ≤ 4.0, 63 (50%) study subjects had a DAS score (disease activity score) between 4.01 and 6.0, and in the remaining 31 (25%) study subjects, the DAS score was >6.0. The mean DAS score among study subjects was 4.96, and the study subjects had a mean activity of daily living (ADL) score of 11.64; controls had a mean score of 2.42 with a statistically significant p-value. The global fatigue index was higher in study subjects, with a mean of 33.16 in contrast with a mean of 14.41 in the controls with a significant p-value. Conclusion: Our study fatigue was a persistent problem, despite treatment. The median level of fatigue experienced by study subjects with RA was high. Therefore, as persistent fatigue is associated with functional loss, fatigue in RA remains an ‘unmet need’ and continues to be ignored by clinicians.

How do stroke survivors and their caregivers manage post-stroke fatigue? A qualitative study

Objectives

The primary objective was to gain insight into the lived experiences of using day-to-day strategies to manage post-stroke fatigue.

Design

Qualitative, descriptive study.

Setting

Community telephone interviews.

Participants

A purposive sample of 20 stroke survivors with current, or previous, post-stroke fatigue, and 8 caregivers, who provided informal care or support, were recruited.

Main Measures

Semi-structured telephone interviews were undertaken. Data were analysed using a framework approach.

Results

Most participants had found their own ways of coping and their personal strategies included acceptance of having fatigue; ‘pacing’ (spreading activities out and interspersing with rest periods); keeping a diary in order to plan activities and to identify ‘trigger’ activities which induced fatigue; talking to (and educating) others about having fatigue; using relaxation; and accessing professional advice and support. The burden placed on caregivers was considerable and they often had to oversee the post-stroke fatigue management strategies used.

Conclusions

Post-stroke fatigue is managed in different ways and there was not one particular strategy that seemed effective for everyone. Most people in our study had had to devise their own ways of coping practically. Given the scale of this problem, which profoundly impacts the lives of both stroke survivors and caregivers, the management of post-stroke fatigue merits more attention and evaluation. However, this must be directly informed by those with lived experience.

Effects of transcranial direct current stimulation on patients with post-stroke fatigue: a study protocol for a double-blind randomized controlled trial

Introduction

Post-stroke fatigue (PSF) is an abnormal, persistent, and unexplained physical and psychological tiredness in patients after stroke. It is a common symptom of stroke patients with poor quality of life and bleak prognosis, and the incidence rate is up to 39% to 72%. It has been widely reported that medicine treatments achieved a lot of progress, there still needs to develop more powerful new strategies to more powerful effect. The transcranial direct-current stimulation (tDCS) shows great potential for the treatment of PSF. This study proposes to apply a double-blind randomized controlled clinical trial to explore the effect and safety of tDCS combined with routine rehabilitation for PSF.

Methods and analysis

One hundred patients with PSF will be randomly divided into two groups. One of the groups will receive conventional rehabilitation therapy and active tDCS, whereas another group will receive conventional rehabilitation treatment and sham tDCS. Both groups will receive the intervention for 4 weeks, during which time they will undergo either active or sham tDCS 20 min a day, 6 days a week. Primary outcome: Fatigue Severity Scale (FSS) will be measured at baseline every weekend during the intervention period. Secondary results: Fatigue Impact Scale (FIS), Functional Assessment Chronic Illness Therapy (Fatigue) (FACIT-F), and Specialized Quality of Life Scale in Stroke (SS-QOL) will be measured at baseline and at the end of the intervention time of 4 weeks. Throughout the study, adverse events and adverse reactions will be measured during every treatment. The research study “Effects of transcranial direct current stimulation on patients with post-stroke fatigue” has been approved by the Ethics Committee of the First Affiliated Hospital of Nanchang University: Clinical Medicine Ethics Review [2015]043 in Nov 2015.

Discussion

This study will provide insight into the efficacy of transcranial direct-current stimulation for post-stroke fatigue. This is a double-blind randomized controlled trial whose aim is to assess the effects of tDCS on PSF. This study can provide more information about the treatment of PSF. This study has a period of follow-up, which allows for greater accuracy. It is a single-center trial, and this may be a limitation. The other limitation of this study is the relatively small number of participants; thus, the influence of chance on experimental results cannot be completely ruled out.

Fatigue is associated with disease activity in some, but not all, patients living with rheumatoid arthritis: disentangling "between-person" and "within-person" associations

Background

Previous research has shown an unclear and inconsistent association between fatigue and disease activity in patients with rheumatoid arthritis (RA). The aim of this study was to explore differences in “between-person” and “within-person” associations between disease activity parameters and fatigue severity in patients with established RA.

Methods

Baseline and 3-monthly follow-up data up to one-year were used from 531 patients with established RA randomized to stopping (versus continuing) tumor necrosis factor inhibitor treatment enrolled in a large pragmatic trial. Between- and within-patient associations between different indicators of disease activity (C-reactive protein [CRP], erythrocyte sedimentation rate [ESR], swollen and tender joint count [ SJC and TJC], visual analog scale general health [VAS-GH]) and patient-reported fatigue severity (Bristol RA Fatigue Numerical Rating Scale) were disaggregated and estimated using person-mean centering in combination with repeated measures linear mixed modelling.

Results

Overall, different indices of disease activity were weakly to moderately associated with fatigue severity over time (β’s from 0.121 for SJC to 0.352 for VAS-GH, all p’s < 0.0001). Objective markers of inflammation (CRP, ESR and SJC) were associated weakly with fatigue within patients over time (β’s: 0.104–0.142, p’s < 0.0001), but not between patients. The subjective TJC and VAS-GH were significantly associated with fatigue both within and between patients, but with substantially stronger associations at the between-patient level (β’s: 0.217–0.515, p’s < 0.0001). Within-person associations varied widely for individual patients for all components of disease activity.

Conclusion

Associations between fatigue and disease activity vary largely for different patients and the pattern of between-person versus within-person associations appears different for objective versus subjective components of disease activity. The current findings explain the inconsistent results of previous research, illustrates the relevance of statistically distinguishing between different types of association in research on the relation between disease activity and fatigue and additionally suggest a need for a more personalized approach to fatigue in RA patients.

Identification and Prediction of Fatigue Trajectories in People With Rheumatoid Arthritis

OBJECTIVE

We aimed to identify groups demonstrating different long-term trajectories of fatigue among people with rheumatoid arthritis and determine baseline predictors for these trajectories.

METHODS

Our study included 2741 people aged 18 to 75 years who were independent in daily living. Data were collected from the Swedish Rheumatology Quality Register and questionnaires at baseline, 14 months, and 26 months. Fatigue was rated on a 100-mm visual analog scale. K-means cluster analysis was used to identify fatigue trajectories. Multinomial logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals for potential predictors of trajectory membership.

RESULTS

The mean age was 60 years, 73% of participants were female, and the mean baseline fatigue level was 39. Three distinct fatigue trajectories were identified, representing mild (mean 15, n = 1024), moderate (mean 41, n = 986), and severe (mean 71, n = 731) fatigue. Consistent patterns indicated that poorer health perception (ORs 1.68-18.40), more pain (ORs 1.38-5.04), anxiety/depression (ORs 0.85-6.19), and activity limitation (ORs 1.43-7.39) were associated with more severe fatigue. Those in the severe fatigue group, compared with those in the mild fatigue group, were more likely to be college educated than university educated (OR 1.56) and less likely to maintain physical activity (OR 0.54). Those in the severe fatigue group, compared with those in both the moderate (OR 0.67) and mild (OR 0.59) fatigue groups, were less likely to have one additional adult in the household.

CONCLUSION

This study identified stable fatigue trajectories, predicted by health perception, pain, anxiety/depression, activity limitation, educational level, maintained physical activity, and household composition. Interventions aimed at reducing these disabilities and supporting physical activity behaviors may help reduce fatigue.

Toward the unity of pathological and exertional fatigue: A predictive processing model

Fatigue is a common experience in both health and disease. Yet, pathological (i.e., prolonged or chronic) and transient (i.e., exertional) fatigue symptoms are traditionally considered distinct, compounding a separation between interested research fields within the study of fatigue. Within the clinical neurosciences, nascent frameworks position pathological fatigue as a product of inference derived through hierarchical predictive processing. The metacognitive theory of dyshomeostasis (Stephan et al., 2016) states that pathological fatigue emerges from the metacognitive mechanism in which the detection of persistent mismatches between prior interoceptive predictions and ascending sensory evidence (i.e., prediction error) signals low evidence for internal generative models, which undermine an agent’s feeling of mastery over the body and is thus experienced phenomenologically as fatigue. Although acute, transient subjective symptoms of exertional fatigue have also been associated with increasing interoceptive prediction error, the dynamic computations that underlie its development have not been clearly defined. Here, drawing on the metacognitive theory of dyshomeostasis, we extend this account to offer an explicit description of the development of fatigue during extended periods of (physical) exertion. Accordingly, it is proposed that a loss of certainty or confidence in control predictions in response to persistent detection of prediction error features as a common foundation for the conscious experience of both pathological and nonpathological fatigue.

A randomized controlled trial to explore the efficacy and safety of transcranial direct current stimulation on patients with post-stroke fatigue

BACKGROUND

Post-stroke fatigue seriously affects the quality of life for stroke patients. There is no effective treatment at present. transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation which may have therapeutic effect on post-stroke fatigue. This study will explore about this.

METHOD

A total of 60 patients with post-stroke fatigue were randomly divided into the control group and the treatment group with 30 patients each by minimization randomization. Both groups received basic treatment and conventional rehabilitation. In the treatment group, patients were treated with active tDCS, while in the control group, sham tDCS. Both active and sham tDCS were administered 6 times a week for 4 weeks. Before and after the trial, the Fatigue Severity Scale (FSS), Fugl-Meyer Assessment (FMA) and Modified Barthel Index (MBI) were evaluated and analyzed. And comparisons were made among groups. And there were an 8-week follow-up after the intervention.

RESULT

Before the intervention, there were no significant differences in baseline data and assessment scores between the groups (P > 0.05). After 4 weeks of intervention, FSS scores in the treatment group were significantly lower than those in the control group (P = 0.012), and FMA and BMI scores were significantly higher than those in the control group (P < 0.05). There was no significant change in FSS scores after 8 months of follow-up (P > 0.05).

DISCUSSION

TDCS is a safe treatment that can effectively reduce the degree of fatigue after stroke, improve the motor function and daily activity ability of patients after stroke, and the efficacy is better than only routine rehabilitation training.

Fatigue-management strategies among women with endometriosis in South Africa: a qualitative study

Fatigue is a common, secondary symptom of endometriosis that has not been qualitatively explored. We conducted individual, face-to-face interviews with 25 women in South Africa about their experiences of endometriosis-related fatigue. Participants were recruited at a public hospital in Cape Town and through several South African endometriosis organizations. Interviews were conducted in English and Afrikaans and ranged from 30 min to 1 hr 16 min in duration. All interviews were audio recorded and transcribed. Interviews were analyzed using thematic analysis. We found that both the experience of fatigue and fatigue-management strategies were highly personalized. Participants reported using a variety of cognitive strategies, such as planning, pacing, and pushing through their fatigue to reduce the levels of fatigue. Participants also employed physical strategies such as rest, dietary changes, using supplements, and exercise. We found that while participants often tried fatigue-management strategies suggested to them by others, they struggled to maintain these strategies even when they were successful. There are currently no interventions aimed at reducing endometriosis-related fatigue. The findings of this study provide insight into the management of fatigue in women with endometriosis and may be used to develop a psychosocial intervention for fatigue among women with the disease.

Perceptions of fatigue and fatigue management interventions among people with multiple sclerosis: a systematic literature review and narrative synthesis

Background/Aims

Fatigue is the most common symptom of multiple sclerosis. Evidence supports the effectiveness of fatigue management interventions for people with multiple sclerosis. This review aimed to identify how people with multiple sclerosis experience fatigue and to examine their perceptions of fatigue management interventions.

Methods

The review was conducted systematically, searching the following electronic databases: AMED, CINAHL Complete, eBook Nursing Collection, ERIC, Health Source: Nursing/Academic Edition, MEDLINE, APA PsycArticles, and APA PsycInfo for original peer-reviewed empirical research published in English between January 2000 and June 2020. Qualitative and mixed-methods studies that captured the perspectives of people with multiple sclerosis on their fatigue and/or their perceptions of fatigue management interventions were included. A narrative synthesis was used to synthesise the findings.

Results

A total of 23 qualitative and eight mixed-methods studies were extracted comprising a total of 662 people with multiple sclerosis (relapsing remitting n=293; secondary progressive n=129; primary progressive n=73; relapsing progressive n=3; benign n=2; fulminant n=1; type of multiple sclerosis not reported n=161). Fatigue was perceived by people with multiple sclerosis as a debilitating symptom of the condition and which they felt impacted adversely on their lives. A lack of understanding from others about multiple sclerosis fatigue was challenging for people with multiple sclerosis. People with multiple sclerosis valued the physical and psychosocial-based content of fatigue management interventions and felt fatigue management interventions enabled them to legitimise their fatigue and feel more in control of their fatigue.

Conclusions

From the perspective of people with multiple sclerosis, fatigue is a central and debilitating feature of the everyday experience of living with multiple sclerosis. Research on the potential of fatigue management interventions to foster control for people with multiple sclerosis to help them manage their fatigue is warranted. Healthcare professionals should consider how they can empower people with multiple sclerosis to educate others about their fatigue. Some evidence being generated for practice might not be sufficiently contextualised to different forms of multiple sclerosis.

How to relate to dialysis patients' fatigue - perspectives of dialysis nurses and renal health professionals: A qualitative study

BACKGROUND

Although fatigue among the dialysis population is known as a severe and debilitating health problem, this symptom is often under recognized and undertreated.

OBJECTIVE

This qualitative study aimed to gain a better understanding of how dialysis nurses and renal health professionals perceive and address dialysis patient's fatigue in renal care practice.

DESIGN

We conducted a qualitative descriptive study to explore how nurses and renal health professionals perceive and address dialysis patients' fatigue in their daily health care practices. A constructivist grounded theory approach guided analysis and conceptualisation of findings.

SETTING(S)

This study took place at 13 academic and regional settings across the Netherlands. The study was approved by the Medical Ethics Committee (2015.049), on behalf of VU University medical center in Amsterdam.

PARTICIPANTS

Twenty-one renal health professionals of various disciplines took part in interviews: ten dialysis nurses, four nephrologists, two physician assistants, five medical social workers.

METHODS

Semi-structured interviews were conducted in order to gain in-depth insight into the perspectives of dialysis nurses and renal health professionals. An inductive thematic analysis provided insight into health professionals' stances toward dialysis patients' fatigue in light of their daily care context and practices.

RESULTS

Two main themes emerged; 1) 'Fatigue in the background': Shows there is strong focus on medical-technical aspects of the disease. All health professionals perceive fatigue as an intangible symptom that is difficult to address, and falls outside their scope of responsibility and competence. Communication about fatigue among professionals and with patients is limited, pushing fatigue further into the background. 2) 'Vulnerabilities in the background': Especially nurses and social workers signal the accumulating vulnerabilities of dialysis patients and associate these with fatigue (old age, multimorbidities, financial and social problems). Although the need for psychological support is acknowledged, multiple vulnerabilities increase the complexity and intensity of care, and further strengthens the medical-technical focus of care and treatment.

CONCLUSIONS

There is a need to enable renal health professionals to communicate about the complex nature of fatigue in renal patients and stimulate interdisciplinary exchange and shared responsibility. Dialysis nurses have frequent contact with patients during dialysis treatment and are the first to notice when patients' fatigue increases and their overall condition deteriorates. They can play an important role to go beyond the technological imperative of care and understand the lived experiences of patients within their social contexts.

Group cognitive-behavioural programme to reduce the impact of rheumatoid arthritis fatigue: the RAFT RCT with economic and qualitative evaluations

BACKGROUND

Fatigue is a major problem in rheumatoid arthritis (RA). There is evidence for the clinical effectiveness of cognitive-behavioural therapy (CBT) delivered by clinical psychologists, but few rheumatology units have psychologists.

OBJECTIVES

To compare the clinical effectiveness and cost-effectiveness of a group CBT programme for RA fatigue [named RAFT, i.e. Reducing Arthritis Fatigue by clinical Teams using cognitive-behavioural (CB) approaches], delivered by the rheumatology team in addition to usual care (intervention), with usual care alone (control); and to evaluate tutors' experiences of the RAFT programme.

DESIGN

A randomised controlled trial. Central trials unit computerised randomisation in four consecutive cohorts within each of the seven centres. A nested qualitative evaluation was undertaken.

SETTING

Seven hospital rheumatology units in England and Wales.

PARTICIPANTS

Adults with RA and fatigue severity of ≥ 6 [out of 10, as measured by the Bristol Rheumatoid Arthritis Fatigue Numerical Rating Scale (BRAF-NRS)] who had no recent changes in major RA medication/glucocorticoids.

INTERVENTIONS

RAFT - group CBT programme delivered by rheumatology tutor pairs (nurses/occupational therapists). Usual care - brief discussion of a RA fatigue self-management booklet with the research nurse.

MAIN OUTCOME MEASURES

Primary - fatigue impact (as measured by the BRAF-NRS) at 26 weeks. Secondary - fatigue severity/coping (as measured by the BRAF-NRS); broader fatigue impact [as measured by the Bristol Rheumatoid Arthritis Fatigue Multidimensional Questionnaire (BRAF-MDQ)]; self-reported clinical status; quality of life; mood; self-efficacy; and satisfaction. All data were collected at weeks 0, 6, 26, 52, 78 and 104. In addition, fatigue data were collected at weeks 10 and 18. The intention-to-treat analysis conducted was blind to treatment allocation, and adjusted for baseline scores and centre. Cost-effectiveness was explored through the intervention and RA-related health and social care costs, allowing the calculation of quality-adjusted life-years (QALYs) with the EuroQol-5 Dimensions, five-level version (EQ-5D-5L). Tutor and focus group interviews were analysed using inductive thematic analysis.

RESULTS

A total of 308 out of 333 patients completed 26 weeks (RAFT, n/N = 156/175; control, n/N = 152/158). At 26 weeks, the mean BRAF-NRS impact was reduced for the RAFT programme (-1.36 units; p < 0.001) and the control interventions (-0.88 units; p < 0.004). Regression analysis showed a difference between treatment arms in favour of the RAFT programme [adjusted mean difference -0.59 units, 95% confidence interval (CI) -1.11 to -0.06 units; p = 0.03, effect size 0.36], and this was sustained over 2 years (-0.49 units, 95% CI -0.83 to -0.14 units; p = 0.01). At 26 weeks, further fatigue differences favoured the RAFT programme (BRAF-MDQ fatigue impact: adjusted mean difference -3.42 units, 95% CI -6.44 to - 0.39 units, p = 0.03; living with fatigue: adjusted mean difference -1.19 units, 95% CI -2.17 to -0.21 units, p = 0.02; and emotional fatigue: adjusted mean difference -0.91 units, 95% CI -1.58 to -0.23 units, p = 0.01), and these fatigue differences were sustained over 2 years. Self-efficacy favoured the RAFT programme at 26 weeks (Rheumatoid Arthritis Self-Efficacy Scale: adjusted mean difference 3.05 units, 95% CI 0.43 to 5.6 units; p = 0.02), as did BRAF-NRS coping over 2 years (adjusted mean difference 0.42 units, 95% CI 0.08 to 0.77 units; p = 0.02). Fatigue severity and other clinical outcomes were not different between trial arms and no harms were reported. Satisfaction with the RAFT programme was high, with 89% of patients scoring ≥ 8 out of 10, compared with 54% of patients in the control arm rating the booklet (p < 0.0001); and 96% of patients and 68% of patients recommending the RAFT programme and the booklet, respectively, to others (p < 0.001). There was no significant difference between arms for total societal costs including the RAFT programme training and delivery (mean difference £434, 95% CI -£389 to £1258), nor QALYs gained (mean difference 0.008, 95% CI -0.008 to 0.023). The probability of the RAFT programme being cost-effective was 28-35% at the National Institute for Health and Care Excellence's thresholds of £20,000-30,000 per QALY. Tutors felt that the RAFT programme's CB approaches challenged their usual problem-solving style, helped patients make life changes and improved tutors' wider clinical practice.

LIMITATIONS

Primary outcome data were missing for 25 patients; the EQ-5D-5L might not capture fatigue change; and 30% of the 2-year economic data were missing.

CONCLUSIONS

The RAFT programme improves RA fatigue impact beyond usual care alone; this was sustained for 2 years with high patient satisfaction, enhanced team skills and no harms. The RAFT programme is < 50% likely to be cost-effective; however, NHS costs were similar between treatment arms.

FUTURE WORK

Given the paucity of RA fatigue interventions, rheumatology teams might investigate the pragmatic implementation of the RAFT programme, which is low cost.

A sanctuary from everyday life: rheumatology patients' experiences of in-patient multidisciplinary rehabilitation - a qualitative study

PURPOSE

To explore how rheumatology patients experience the personal impact of an inpatient rehabilitation stay and to elucidate the impact of contextual factors on the outcome.

METHODS

Exploratory qualitative individual interviews were conducted with 15 rheumatology patients (73% female) who had completed a two-week inpatient rehabilitation stay. Data collection, analysis and interpretation of data were performed within a phenomenological-hermeneutic framework inspired by Paul Ricoeur's interpretative philosophy.

RESULTS

The analysis derived one core theme, A sanctuary from everyday life, and five subthemes: (1) Being seen, heard and acknowledged as an equal and whole person; (2) Professional care and compassion; (3) Social relations and interactions between patients; (4) Individual rehabilitation, but challenges regarding shared decision making; and (5) Rehabilitation as a personal process but problems with coherence and transferability of learning to everyday life.

CONCLUSION

Patients experience inpatient rehabilitation as a sanctuary, in the following three ways; through individually planned multidisciplinary interventions at the hospital; recognition and compassion from the multidisciplinary staff and through social relationships and interactions with fellow patients. There is a need for improved coordination across primary and secondary health care, to ease coherence and transfer of learning to the patients' everyday lives.IMPLICATIONS FOR REHABILITATIONPatients can find peace and energy to care for themselves because they are away from everyday life when admitted for inpatient multidisciplinary rehabilitation.Patients need to be prepared for shared decision-making in order to be able to participate in formulating personal and meaningful goals for rehabilitation.There is a need for awareness of organisational and life transitions, to secure transfer of elements from the rehabilitation stay to the patient's everyday life.Rehabilitation professionals should be aware of the significance of fellow patients and facilitate and support the patient-patient relationships.

Correlations of fatigue in Danish patients with rheumatoid arthritis, psoriatic arthritis and spondyloarthritis

Objective

To describe fatigue in relation to disease-specific and socioeconomic factors and to test possible correlations between fatigue and work impairment, quality of life, pain, sleep, depression, and physical functioning in people with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (axSpA).

Methods

A questionnaire-based cross-sectional survey collecting patient characteristics such as disease characteristics, socioeconomic factors and patient-reported outcomes (PROs) from patients with RA, PsA and axSpA in Denmark. PRO scales included the FACIT-Fatigue sub-scale, Work Productivity and Activity Impairment scale (WPAI), EuroQol (EQ-5D), Medical Outcomes Study Sleep Scale (MOS), Major Depression Inventory (MDI), and Health Assessment Questionnaire (HAQ). Respondents were recruited via routine visits to the outpatient rheumatology clinic; information on diagnosis, treatment and disease activity was collected from medical journals by trained nurses.

Results

487 patients participated in the study. Fatigue was more present in women, experienced patients, and patients who changed medication in the past 12 months, who were unemployed, who had less education, and who had lower household income. There was no statistically significant difference between mean fatigue in the three diagnostic groups (p = 0.08). Fatigue correlated with all included PROs (Pearson correlation coefficients, p<0.0001). Stratifying for diagnosis and adjusting for socioeconomic factors did not change the conclusion.

Conclusion

In a stable, representative group of patients with RA, PsA and axSpA, we found significant correlations between fatigue and work impairment, quality of life, pain, sleep, depression and physical functioning. Fatigue cannot be perceived as a single problem, but rather as a symptom that affects broadly.

The experience of living with rheumatoid arthritis: A qualitative metasynthesis

AIMS AND OBJECTIVES

To develop a model of understanding of how rheumatoid arthritis (RA) affects daily life based on a third-order interpretation of qualitative findings.

BACKGROUND

Rheumatoid arthritis is a chronic condition subject to a progressive deterioration of joints, limiting the ability to move and causing severe impairment in patients' lives.

DESIGN

A qualitative metasynthesis.

METHODS

CINHAL, ProQuest, PsycINFO, PubMed, SCOPUS and Web of Science databases were searched for relevant studies applying appropriate criteria. Screening and selection of studies were performed following the PRISMA guidelines and the PRISMA checklist was completed. Thirty-eight qualitative articles were retrieved: in total, 17 were excluded for failing to meet inclusion criteria, and 21 were considered for synthesis. Data analysis followed a third-order interpretation of data for synthesising qualitative research.

RESULTS

Findings led to the creation of a model consisting of two overarching categories: "rheumatoid arthritis impact on life domains" and "Confronting the illness," and two cross-sectional codes: "Health" and "Independence and normality."

CONCLUSION

This meta-study provides a model that is both inclusive of participants' own viewpoint and solidly grounded in a health psychology model.

RELEVANCE TO CLINICAL PRACTICE

The model can be highly informative for both practitioners and researchers in developing tailored interventions of support and prevention.

Exploring the role of online health information and social media in the illness experience of arthritis-related fatigue: A focus group study

PURPOSE

Online health information (OHI) and social media have become prominent health resources for people with arthritis-related fatigue. More research is needed to understand how OHI and online social support may influence illness experiences and patient-practitioner relationships in people with arthritis-related fatigue. The present study aimed to explore how OHI and social media shape these experiences by using an inductive qualitative analysis.

METHOD

Seven focus groups were conducted with 21 participants aged 28-77 diagnosed with a range of rheumatic diseases. Within the focus groups, participants were asked questions about OHI, online social support and the role of OHI in their health care. The focus groups were recorded, transcribed and analysed using a combination of interpretative phenomenological analysis (IPA) and thematic analysis.

RESULTS

The analysis resulted in three themes: (a) how online social support changes illness experiences, (b) communicating fatigue to health professionals using OHI and (c) health care experiences online. These themes provide insight into the ways people with arthritis-related fatigue benefit from online social support, use OHI to support communication with health professionals and how they share health care for arthritis in online spaces.

CONCLUSION

This research expanded on previous literature addressing the role of OHI and social media in the illness experience of arthritis-related fatigue. As technology use is increasing, particularly in the current extraordinary environment of social distancing, it is critical to address the role of OHI and social media in health care. In this study, OHI and social media played a prevalent role in the health care of many participants.

A Qualitative Metasynthesis of the Experience of Fatigue Across Five Chronic Conditions

CONTEXT

Fatigue is a symptom reported by patients with a variety of chronic conditions. However, it is unclear whether fatigue is similar across conditions. Better understanding its nature could provide important clues regarding the mechanisms underlying fatigue and aid in developing more effective therapeutic interventions to decrease fatigue and improve quality of life.

OBJECTIVES

To better understand the nature of fatigue, we performed a qualitative metasynthesis exploring patients' experiences of fatigue across five chronic noninfectious conditions: heart failure, multiple sclerosis, rheumatoid arthritis, chronic kidney disease, and chronic obstructive pulmonary disease.

METHODS

We identified 34 qualitative studies written in the last 10 years describing fatigue in patients with one of the aforementioned conditions using three databases (Embase, PubMed, and CINAHL). Studies with patient quotes describing fatigue were synthesized, integrated, and interpreted.

RESULTS

Across conditions, patients consistently described fatigue as persistent overwhelming tiredness, severe lack of energy, and physical weakness that worsened over time. Four common themes emerged: running out of batteries, a bad life, associated symptoms (e.g., sleep disturbance, impaired cognition, and depression), and feeling misunderstood by others, with a fear of not being believed or being perceived negatively.

CONCLUSION

In adults with heart failure, multiple sclerosis, rheumatoid arthritis, chronic kidney disease, and chronic obstructive pulmonary disease, we found that fatigue was characterized by severe energy depletion, which had negative impacts on patients' lives and caused associated symptoms that exacerbated fatigue. Yet, fatigue is commonly misunderstood and inadequately acknowledged.

Bristol rheumatoid arthritis fatigue scale is valid in patients with psoriatic arthritis and is associated with overall severe disease and higher comorbidities

AIMS

To (1) determine the reliability and validity of the Bristol Rheumatoid Arthritis Fatigue scale (BRAF-NRS) in patients with psoriatic arthritis (PsA) and (2) examine possible clinical associations of worse fatigue in PsA.

METHODS

Study phase 1: BRAF-NRS scale validation cohort. A consecutive cohort of 70 PsA patients was recruited to complete the 3-item BRAF-NRS and the 13-item Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) questionnaires, alongside disease activity assessment. All patients also completed the BRAF-NRS questionnaire, 1 day later. Study phase 2: Identifying the potential clinical associations of fatigue by using BRAF-NRS (n = 283). A second cohort of 283 PsA patients underwent detailed skin and rheumatologic assessments including disease activity measures. Comorbidities were measured using the Charlson comorbidity index (CCI). Factors predicting worse fatigue as measured by BRAF-NRS were determined using regression analysis.

RESULTS

In phase 1, 67 out of 70 patients from the first cohort had complete assessments. The internal consistency of BRAF-NRS as measured by Cronbach's alpha was 0.92. Test-retest reliability as measured by the intra-class correlation coefficient was 0.97. There was excellent correlation between the BRAF-NRS and FACIT-F score(r = - 0.83) (p = <0.001, 95% CI - 0.74 to - 0.91). In phase 2, using data from the second cohort of 283 PsA patients, possible clinical associations of worse fatigue were examined. On multiple linear regression analyses, the model predicted significant association of worse fatigue scores with low education status (p = 0.03), number of deformed joints (p = 0.01), not achieving minimal disease activity state (p < 0.001), higher CCI scores, and worse health assessment questionnaire score (p < 0.001).

CONCLUSIONS

BRAF-NRS is a reliable, reproducible, and valid instrument for measuring fatigue in PsA. Fatigue in PsA is associated with low education status and overall more severe disease.Key Points• Fatigue is increasingly recognized as an important measure to examine among patients with PsA, but the available valid fatigue scores in PsA are relatively long and time-consuming especially when other core domains also need to be measured• BRAF-NRS is a short, easily readable, only 3-item tool to measure fatigue, and this is the first study which has examined its performance among the patients with PsA. Our results show that it is a reliable, reproducible, and valid (construct validity) instrument for measuring fatigue in PsA• This study also clearly showed a significant positive relationship between fatigue and comorbidities, and it was also found that comorbidities play the largest role in the multivariate model.

The role of non-pharmacological interventions in the management of rheumatoid-arthritis-related fatigue

Non-pharmacological interventions may be beneficial in the management of rheumatoid arthritis related fatigue. A narrative review was undertaken, with a focus upon research published in the past 6 years. Seven studies were identified, four focusing upon physical activity, two on psychosocial interventions and one that investigated aromatherapy and reflexology. Findings supported previous evidence that physical activity and psychosocial interventions have potential to produce small to moderate reductions in fatigue related to rheumatoid arthritis. Reflexology and aromatherapy interventions also appeared promising. Limitations to the evidence included lack of consistency in fatigue measurement, and minimal data on long-term outcomes and cost effectiveness. The wide range of physical activity interventions prevent specific recommendations. For psychosocial interventions the strongest evidence is for group-based cognitive behavioural approaches. There was lack of consideration given to fatigue mechanisms and intervention design. Due to the complexity of fatigue, future research exploring personalized approaches is warranted.

Oncology nurses' experiences of meeting with men with cancer-related fatigue: a qualitative study

BACKGROUND

Cancer treatment often causes side effects, among which fatigue is common and can persist for years among disease-free cancer survivors. Living with fatigue can lead to reduced life expectancy and quality of life.

AIMS AND OBJECTIVES

To describe oncology nurses' experiences of meeting with men with cancer and talking about cancer-related fatigue.

DESIGN AND METHODS

The data were collected via semi-structured interviews with nine oncology nurses recruited using a purposeful sampling method and analysed using thematic content analysis. This qualitative design was conducted to describe and interpret the content of experiences.

ETHICAL ISSUES AND APPROVAL

The study was approved by a regional Ethical Review Board, and research ethical principles were followed.

RESULTS

The analysis revealed one major theme, namely take the whole person into consideration, and three subthemes: the importance of (i) establishing trust in the nurse-patient relationship, (ii) supporting the patient's understanding of cancer-related fatigue, and (iii) managing the challenging emotions experienced by patients. The major theme describes the oncology nurses' approach when meeting with men with cancer-related fatigue.

CONCLUSION

The results provide insight into how oncology nurses can increase their knowledge about fatigue to establish trust in nurse-patient relationships. They can acquire knowledge about how to make men with cancer-related fatigue feel safe when handling their daily lives despite their fatigue. Oncology nurses require knowledge, presence and commitment in their interactions with men with cancer-related fatigue to be able to take the whole person into consideration. This study demonstrates the importance of the approach oncology nurses take when interacting with men with cancer-related fatigue and the strategies required when talking about cancer-related fatigue.

Changes in mechanical loading affect arthritis-induced bone loss in mice

Arthritis induces bone loss by inflammation-mediated disturbance of bone homeostasis. On the other hand, pain and impaired locomotion are highly prevalent in arthritis and result in reduced general physical activity and less pronounced mechanical loading. Bone is affected by mechanical loading, directly through impact with the ground during movement and indirectly through muscular activity. Mechanical loading in its physiological range is essential for maintaining bone mass, whereas disuse leads to bone loss. The aim of this study was to investigate the impact of mechanical loading on periarticular bone as well as inflammation during arthritis. Mechanical loading was either blocked by botulinum neurotoxin A (Botox) injections before induction of arthritis, or enhanced by cyclic compressive loading, three times per week during arthritis induction. Arthritis was verified and evaluated histologically. Trabecular and cortical bone mass were investigated using micro-computed tomography (μCT), subchondral osteoclastogenesis and bone turnover was assessed by standard methods. Inhibition of mechanical loading enhanced arthritis-induced bone loss while it did not affect inflammation. In contrast, enhanced mechanical loading mitigated arthritis-induced bone loss. Furthermore, the increase in bone resorption markers by arthritis was partly blocked by mechanical loading. In conclusion, enhanced arthritic bone loss after abrogation of mechanical loading suggests that muscle forces play an essential role in preventing arthritic bone loss. In accordance, mechanical loading of the arthritic joints inhibited bone loss, emphasizing that weight bearing activities may have the potential to counteract arthritis-mediated bone loss.

"Mastering a New Life Situation" - Patients' Preferences of Treatment Outcomes in Early Rheumatoid Arthritis - A Longitudinal Qualitative Study

PURPOSE

To explore patients' preferred treatment outcomes during their first two years with rheumatoid arthritis (RA).

PATIENTS AND METHODS

A qualitative, longitudinal, multicenter study with interviews at two time points was performed in Sweden. Individual interviews were conducted at time point 1 with 31 patients with RA, defined as disease duration of ≤1 year and treatment for 3-7 months. Seven focus group interviews and five individual interviews were conducted at time point 2 with 22 patients 12-20 months after treatment initiation. The interviews were analyzed using the Qualitative Analysis Guide of Leuven. A core category with four related concepts emerged.

RESULTS

The core finding of patient-preferred treatment outcomes was "mastering a new life situation". Patients preferred to experience control of the disease by controlling the symptoms and by experiencing absence of disease. To experience autonomy by regaining former activity level, experiencing independence, and being empowered was another preferred outcome. Patients preferred to regain identity through being able to participate, experience well-being, and regain former self-image. To experience joy in everyday life through vitality and believing in the future was another preferred outcome. Patients' preferences developed over time from the acute phase of controlling the symptoms and wanting to return to the life they lived prior to diagnosis, to a more preventive way of self-management and empowerment to master the new life situation.

CONCLUSION

The patients' preferred treatment outcomes during the first two years with RA were to master their new life situation and changed from a preference to return to a life lived prior disease onset, to a preference of living with quality of life, despite RA. This study increases the understanding of patients' preferred treatment outcomes in the early disease course and can be a foundation for tailoring interventions to be more person-centered and to improve long-term treatment outcomes.

Factors of importance for reducing fatigue in persons with rheumatoid arthritis: a qualitative interview study

OBJECTIVE

Physical activity plays an important role in the treatment of persons with rheumatoid arthritis (RA) and is the non-pharmacological intervention with the strongest evidence to reduce fatigue. However, physical activity can be challenging for persons who are fatigued. The aim of this study was to investigate factors of importance for reducing fatigue in persons with RA.

DESIGN

This is a qualitative interview study based on semistructured, indepth individual interviews. Interviews were analysed using qualitative content analysis.

PARTICIPANTS

Participants were 12 people with RA recruited from a previous randomised controlled trial of a person-centred treatment model focusing on health-enhancing physical activity and daily balance to lessen fatigue in persons with RA.

SETTING

Interviews were conducted in a hospital setting.

RESULTS

The analysis resulted in one theme: an intellectual and embodied understanding that sustainable physical activity is important to handle fatigue. This included five categories describing barriers and facilitating factors for sustainable physical activity: mentally overcoming the fatigue in order to be active, making exercise easy, reaching for balance, receiving support to be physically active and dealing with RA disease to be physically active.

CONCLUSION

The participants in this study expressed that physical activity was important in handling fatigue, but also that this insight could only come from personal experience. The use of a person-centred ethic in physiotherapy coaching for patients with fatigue appears to promote sustainable physical activity behaviours by facilitating patients' resources to overcome barriers to physical activity.

Developing a group intervention to manage fatigue in rheumatoid arthritis through modifying physical activity

Background

Fatigue is a major symptom of rheumatoid arthritis (RA). There is some evidence that physical activity (PA) may be effective in reducing RA fatigue. However, few PA interventions have been designed to manage fatigue and there is limited evidence of end-user input into intervention development. The aim of this research was to co-design an intervention to support self-management of RA fatigue through modifying PA.

Methods

A series of studies used mixed methodological approaches to co-design a fatigue management intervention focused on modifying PA based on UK Medical Research Council guidance, and informed by the Behaviour Change Wheel theoretical framework. Development was based on existing evidence, preferences of RA patients and rheumatology healthcare professionals, and practical issues regarding intervention format, content and implementation.

Results

The resulting group-based intervention consists of seven sessions delivered by a physiotherapist over 12 weeks. Each session includes an education and discussion session followed by supervised PA chosen by the participant. The intervention is designed to support modification and maintenance of PA as a means of managing fatigue. This is underpinned by evidence-based behaviour change techniques that might support changes in PA behaviour. Intervention delivery is interactive and aims to enhance capability, opportunity and motivation for PA.

Conclusion

This study outlines stages in the systematic development of a theory-based intervention designed through consultation with RA patients and healthcare professionals to reduce the impact of RA fatigue. The feasibility of future evaluation of the intervention should now be determined.

Efficacy of a Web-Based Self-Management Enhancing Program for Patients with Rheumatoid Arthritis: Explorative Randomized Controlled Trial

Background

Web-based self-management enhancing programs have the potential to support patients with rheumatoid arthritis (RA) in their self-management; for example, improve their health status by increasing their self-efficacy or taking their prescribed medication. We developed a Web-based self-management enhancing program in collaboration with RA patients and professionals as co-designers on the basis of the intervention mapping framework. Although self-management programs are complex interventions, it is informative to perform an explorative randomized controlled trial (RCT) before embarking on a larger trial.

Objective

This study aimed to evaluate the efficacy of a Web-based self-management enhancing program for patients with RA and identify outcome measures most likely to capture potential benefits.

Methods

A multicenter exploratory RCT was performed with an intervention group and a control group. Both groups received care as usual. In addition, the intervention group received 12 months of access to a Web-based self-management program. Assessment occurred at baseline, 6 months, and 12 months. Outcome measures included self-management behavior (Patient Activation Measurement, Self-Management Ability Scale), self-efficacy (Rheumatoid Arthritis task-specific Self-Efficacy, Perceived Efficacy in Patient-Physician Interaction), general health status (RAND-36), focus on fatigue (Modified Pain Coping Inventory for Fatigue), and perceived pain and fatigue (Numeric Rating Scales). A linear mixed model for repeated measures, using the intention-to-treat principle, was applied to study differences between the patients in the intervention (n=78) and control (n=79) groups. A sensitivity analysis was performed in the intervention group to study the influence of patients with high (N=30) and low (N=40) use of the intervention.

Results

No positive effects were found regarding the outcome measurements. Effect sizes were low.

Conclusions

Based on these results, it is not possible to conclude on the positive effects of the intervention or to select outcome measures to be regarded as the primary/main or secondary outcomes for a future trial. A process evaluation should be performed to provide more insight into the low compliance with and effectiveness of the intervention. This can determine for whom this sort of program will work and help to fine-tune the inclusion criteria.

Reducing arthritis fatigue impact: two-year randomised controlled trial of cognitive behavioural approaches by rheumatology teams (RAFT)

OBJECTIVES

To see if a group course delivered by rheumatology teams using cognitive-behavioural approaches, plus usual care, reduced RA fatigue impact more than usual care alone.

METHODS

Multicentre, 2-year randomised controlled trial in RA adults (fatigue severity>6/10, no recent major medication changes). RAFT (Reducing Arthritis Fatigue: clinical Teams using CB approaches) comprises seven sessions, codelivered by pairs of trained rheumatology occupational therapists/nurses. Usual care was Arthritis Research UK fatigue booklet. Primary 26-week outcome fatigue impact (Bristol RA Fatigue Effect Numerical Rating Scale, BRAF-NRS 0-10). Intention-to-treat regression analysis adjusted for baseline scores and centre.

RESULTS

308/333 randomised patients completed 26 week data (156/175 RAFT, 152/158 Control). Mean baseline variables were similar. At 26 weeks, the adjusted difference between arms for fatigue impact change favoured RAFT (BRAF-NRS Effect -0.59, 95% CI -1.11 to -0.06), BRAF Multidimensional Questionnaire (MDQ) Total -3.42 (95% CI -6.44 to -0.39), Living with Fatigue -1.19 (95% CI -2.17 to -0.21), Emotional Fatigue -0.91 (95% CI -1.58 to -0.23); RA Self-Efficacy (RASE, +3.05, 95% CI 0.43 to 5.66) (14 secondary outcomes unchanged). Effects persisted at 2 years: BRAF-NRS Effect -0.49 (95% CI -0.83 to -0.14), BRAF MDQ Total -2.98 (95% CI -5.39 to -0.57), Living with Fatigue -0.93 (95% CI -1.75 to -0.10), Emotional Fatigue -0.90 (95% CI -1.44, to -0.37); BRAF-NRS Coping +0.42 (95% CI 0.08 to 0.77) (relevance of fatigue impact improvement uncertain). RAFT satisfaction: 89% scored > 8/10 vs 54% controls rating usual care booklet (p<0.0001).

CONCLUSION

Multiple RA fatigue impacts can be improved for 2 years by rheumatology teams delivering a group programme using cognitive behavioural approaches.

The Experience of people with rheumatoid arthritis living with fatigue: a qualitative metasynthesis

OBJECTIVES

To identify, appraise and synthesise qualitative studies on the experience of living with rheumatoid arthritis (RA)-related fatigue.

METHODS

We conducted a qualitative metasynthesis encompassing a systematic literature search in February 2017, for studies published in the past 15 years, in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Embase, SveMed, PsychINFO and Web of Science. To be included, the studies had to report the experience of living with fatigue among adults with RA. The analysis and synthesis followed Malterud's systematic text condensation.

RESULTS

Eight qualitative articles were included, based on 212 people with RA (69% women) and aged between 20 and 83 years old. The synthesis resulted in the overall theme 'A vicious circle of an unpredictable symptom'. In addition, the synthesis derived four subthemes: 'being alone with fatigue'; 'time as a challenge'; 'language as a tool for increased understanding' and 'strategies to manage fatigue'. Fatigue affects all areas of everyday life for people with RA. They strive to plan and prioritise, pace, relax and rest. Furthermore, they try to make use of a variety of words and metaphors to explain to other people that they experience that RA-related fatigue is different from normal tiredness. Despite this, people with RA-related fatigue experience feeling alone with their symptom and they develop their own strategies to manage fatigue in their everyday life.

CONCLUSIONS

The unpredictability of RA-related fatigue is dominant, pervasive and is experienced as a vicious circle, which can be described in relation to its physical, cognitive, emotional and social impact. It is important for health professionals to acknowledge and address the impact of fatigue on the patients' everyday lives. Support from health professionals to manage fatigue and develop strategies to increase physical activity and maintain work is important for people with RA-related fatigue.

Juvenile Arthritis Patients Suffering from Chronic Inflammation Have Increased Activity of Both IDO and GTP-CH1 Pathways But Decreased BH4 Efficacy: Implications for Well-Being, Including Fatigue, Cognitive Impairment, Anxiety, and Depression

Juvenile idiopathic arthritis (JIA) represents joint inflammation with an unknown cause that starts before the age of 16, resulting in stiff and painful joints. In addition, JIA patients often report symptoms of sickness behavior. Recent animal studies suggest that proinflammatory cytokines produce sickness behavior by increasing the activity of indoleamine-2,3-dioxygenase (IDO) and guanosinetriphosphate⁻cyclohydrolase-1 (GTP⁻CH1). Here, it is hypothesized that inflammation in JIA patients enhances the enzymatic activity of IDO and GTP-CH1 and decreases the co-factor tetrahydrobiopterin (BH4). These compounds play a crucial role in the synthesis and metabolism of neurotransmitters. The aim of our study was to reveal whether inflammation affects both the GTP-CH1 and IDO pathway in JIA patients. Serum samples were collected from twenty-four JIA patients. In these samples, the concentrations of tryptophan (TRP), kynurenine (KYN), tyrosine (TYR), neopterin, and phenylalanine (PHE) were measured. An HPLC method with electrochemical detection was developed to quantify tryptophan, kynurenine, and tyrosine. Neopterin and phenylalanine were quantified by ELISA. The KYN/TRP ratio was measured as an index of IDO activity, while the PHE/TYR ratio was measured as an index of BH4 activity. Neopterin concentrations were used as an indirect measure of GTP-CH1 activity. JIA patients with high disease activity showed higher levels of both neopterin and kynurenine, and a higher ratio of both KYN/TRP and PHE/TYR and lower tryptophan levels than clinically inactive patients. Altogether, these data support our hypothesis that inflammation increases the enzymatic activity of both IDO and GTP-CH1 but decreases the efficacy of the co-factor BH4. In the future, animal studies are needed to investigate whether inflammation-induced changes in these enzymatic pathways and co-factor BH4 lower the levels of the brain neurotransmitters glutamate, noradrenaline, dopamine, serotonin, and melatonin, and consequently, whether they may affect fatigue, cognition, anxiety, and depression. Understanding of these complex neuroimmune interactions provides new possibilities for Pharma-Food interventions to improve the quality of life of patients suffering from chronic inflammation.

Associations between fatigue and physical capacity in people moderately affected by rheumatoid arthritis

To explore the contribution of physical capacity in explaining variations in fatigue among people with rheumatoid arthritis (RA). This study included participants recruited for a physical activity intervention. Data were collected from the Swedish Rheumatology Quality Registers, from questionnaires on fatigue, activity limitation, perceived health, pain and anxiety/depression and from physical capacity tests (lower limb function, grip strength, and aerobic capacity). We used logistic regression to estimate the association between severe fatigue (≥ 50, visual analogue scale 0–100) and (A) independent variables related to disease and disease impact and (B) model A plus physical capacity tests. Pooled odds ratio tests compared model fit. Out of the 269 participants (mean age 60 years, mean disease activity score [DAS28] 2.8), severe fatigue was reported by 35%. The three variables which were statistically significantly associated with severe fatigue (p < 0.05) in both models were perceived health, pain and anxiety/depression. Anxiety/depression demonstrated the largest effect size with odds ratios of 2.43 (95% CI 1.20, 4.94) in model A and 2.58 (95% CI 1.25, 5.32) in model B. The likelihood ratio test indicated that model B was a better fit to the data than model A with Χ² (df 3) = 2.65, p = 0.048. Severe fatigue in people with RA is associated with self-rated health, pain and anxiety/depression rather than with physical capacity. Future studies should be prospective, use multidimensional assessments of fatigue to explore the influence of physical capacity and control for possible influence of comorbidities associated with fatigue.

Living With Rheumatoid Arthritis in Spain: A Qualitative Study of Patient Experience and the Role of Health Professionals

The aim of this study was to explore the experience of Spanish people living with rheumatoid arthritis (RA) and the support these people received from health professionals, particularly nurses. Nineteen patients with >1 year diagnosis, disease activity moderate or severe (DAS28 > 3.2), and already treated with disease-modifying antirheumatic drugs (DMARDs) were interviewed. A thematic analysis was performed to interpret the discourses. The difficulties of symptom management; the need for home-adaptations, the difficulties of living with a deteriorating self-image; and the reluctant reliance on medication to control their disease were the main themes that emerged from the discourse analysis of this study. Nurses appeared to have a limited role in RA patients care, and focused primarily on giving information and training for biological therapies. RA patients in Spain would benefit from having contact with specialist nurses who could empower them to self-manage their disease, as happens in other countries.

Fatigue independently predicts different work disability dimensions in etanercept-treated rheumatoid arthritis and ankylosing spondylitis patients

Background

Work disability remains a significant problem in ankylosing spondylitis (AS) and rheumatoid arthritis (RA), despite biological therapy. This study aimed to test the hypothesis that the prevalent symptom of fatigue longitudinally predicts work disability among RA and AS patients commencing etanercept.

Methods

Two observational studies, comprising RA and AS etanercept commencers, respectively, were analysed. Both provided data on work disability over 1 year and a comprehensive set of putative predictors, including fatigue. A series of repeated measures models were conducted, including baseline variables, visit (6/12 months), and the interaction between visit and each of the explanatory variables.

Results

A total of 1003 AS and 1747 RA patients were assessed. For AS, fatigue was significantly associated with presenteeism (linear mixed model coefficient 3.75, 95% confidence interval (CI) 2.14 to 5.36) and activity impairment (2.62, 1.26 to 3.98), but not with work productivity loss (1.81, −0.40 to 4.02) or absenteeism (generalised linear mixed model odds ratio (OR) 1.18, 95% CI 0.92 to 1.51). In RA, fatigue was associated with presenteeism (coefficient 3.44, 95% CI 2.17 to 4.70), activity impairment (1.52, 0.79 to 2.26), work productivity loss (4.16, 2.47 to 5.85), and absenteeism (OR 1.23, 95% CI 1.02 to 1.49). The lack of significant interactions between fatigue and visit supported a consistent effect of baseline fatigue over time.

Conclusions

Among patients beginning etanercept therapy, fatigue has a significant and independent effect on absenteeism, presenteeism, productivity loss, and activity impairment for RA patients and a significant but dimension-selective effect on work disability among AS patients.

'It's when you're not doing too much you feel tired': A qualitative exploration of fatigue in end-stage kidney disease

BACKGROUND

Fatigue is commonly experienced in end-stage kidney disease (ESKD) patients. In order to develop patient-centred psychosocial interventions to help patients manage fatigue symptoms, a more in-depth understanding regarding the experience of fatigue is needed.

OBJECTIVE

The objective of this study was to explore renal patients' experiences of fatigue, across renal replacement therapy (RRT) modalities.

METHODS

Twenty-five in-depth semi-structured interviews were conducted. Interviews were audio-taped, transcribed, and analysed using inductive thematic analysis.

RESULTS

Main themes included the strong role of the illness and treatment in the aetiology of fatigue. Two contrasting streams of illness-fatigue interpretations emerged: catastrophizing versus normalizing. Participants emphasized the importance of having a sense of purpose in facilitating active management of fatigue. Many participants described the consequences of fatigue on their functioning. Low mood, frustration, and anger were common emotional consequences of fatigue. Three dominant fatigue management strategies emerged: one related to accommodation of activities around fatigue, another on increasing activities to counteract fatigue, and the third one revolved around self-compassion. Social support emerged as an important aspect of the fatigue experience, serving as a source of motivation, yet participants were wary of becoming a burden to others.

CONCLUSION

Findings identify casual attributions, behavioural and emotional reactions, management strategies, and facilitators of active management of fatigue in ESKD. Untying fatigue from the illness and treatment may help patients to develop alternative less catastrophic perceptions of fatigue, increase their perception of control over fatigue, and facilitate active fatigue management. Statement of contribution What is already known on this subject? Fatigue is persistent and debilitating in end-stage kidney disease (ESKD), with no consistent treatment model. Promising evidence is available for psychological fatigue interventions in other chronic conditions. There is a gap in studies looking at the fatigue experiences of patients with ESKD across renal replacement therapies. What does this study add? Fatigue is not inherently negative, but shaped by patients' beliefs and behaviours. Findings provide novel insights, for example, on the important role social support seems to play in fatigue. An in-depth understanding of fatigue may help to inform a future patient-centred intervention in ESKD.

Physical activity and autoimmune diseases: Get moving and manage the disease

Physical activity, by definition, is any skeletal muscle body movement that results in energy expenditure. In the last few decades, a plethora of scientific evidences have accumulated and confirmed the beneficial role of physical activity as a modifiable risk factor for a wide variety of chronic diseases including cardiovascular diseases (CVDs), diabetes mellitus and cancer, among others. Autoimmune diseases are a heterogeneous group of chronic diseases, which occur secondary to loss of self-antigen tolerance. With the advent of biological therapies, better outcomes have recently been noted in the management of autoimmune diseases. Nonetheless, recent research highlights the salient role of modifiable behaviors such as physical inactivity on various aspects of the immune system and autoimmune diseases. Physical activity leads to a significant elevation in T-regulatory cells, decreased immunoglobulin secretion and produces a shift in the Th1/Th2 balance to a decreased Th1 cell production. Moreover, physical activity has been proven to promote the release of IL-6 from muscles. IL-6 released from muscles functions as a myokine and has been shown to induce an anti-inflammatory response through IL-10 secretion and IL-1β inhibition. Physical activity has been shown to be safe in most of autoimmune diseases including systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), multiple sclerosis (MS), inflammatory bowel diseases (IBD), as well as others. Additionally, the incidence of RA, MS, IBD and psoriasis has been found to be higher in patients less engaged in physical activity. As a general trend, patients with autoimmune diseases tend to be less physically active as compared to the general population. Physically active RA patients were found to have a milder disease course, better cardiovascular disease (CVD) profile, and improved joint mobility. Physical activity decreases fatigue, enhances mood, cognitive abilities and mobility in patients with MS. In SLE patients, enhanced quality of life and better CVD profile were documented in more physically active patients. Physically active patients with type 1 diabetes mellitus have a decreased risk of autonomic neuropathy and CVD. Both fibromyalgia and systemic sclerosis patients report decreased disease severity, pain, as well as better quality of life with more physical activity. Further, SSc patients improve their grip strength, finger stretching and mouth opening with increased level of exercise. The purpose of this paper is to review the clinical evidence regarding the safety, barriers to engagement, and impact of physical activity on autoimmune diseases.

Exploring the patient perspective of fatigue in adults with visual impairment: a qualitative study

OBJECTIVES

Fatigue is an often mentioned symptom by patients with irreversible visual impairment. This study explored the patient perspective of fatigue in visually impaired adults with a focus on symptoms of fatigue, causes, consequences and coping strategies.

SETTING

Two large Dutch low vision multidisciplinary rehabilitation organisations.

PARTICIPANTS

16 visually impaired adults with severe symptoms of fatigue selected by purposive sampling.

METHODS

A qualitative study involving semistructured interviews. A total of four first-level codes were top-down predetermined in correspondence with the topics of the research question. Verbatim transcribed interviews were analysed with a combination of a deductive and inductive approach using open and axial coding.

RESULTS

Participants often described the symptoms of fatigue as a mental, daily and physical experience. The most often mentioned causes of fatigue were a high cognitive load, the intensity and amount of activities, the high effort necessary to establish visual perception, difficulty with light intensity and negative cognitions. Fatigue had the greatest impact on the ability to carry out social roles and participation, emotional functioning and cognitive functioning. The most common coping strategies were relaxation, external support, socialising and physical exercise and the acceptance of fatigue.

CONCLUSIONS

Our results indicate that low vision-related fatigue is mainly caused by population specific determinants that seem different from the fatigue experience described in studies with other patient populations. Fatigue may be central to the way patients react, adapt and compensate to the consequences of vision loss. These findings indicate a need for future research aimed at interventions specifically tailored to the unique aspects of fatigue related to vision loss.

Causes and consequences of fatigue in rheumatoid arthritis

PURPOSE OF REVIEW

To review current information on the causes, treatments, and consequences of fatigue in rheumatoid arthritis.

RECENT FINDINGS

Disease activity (inflammation, pain, joint symptoms) is associated with greater fatigue. However, disease activity per se accounts for only a small portion of fatigue, and rheumatoid arthritis medications that reduce disease activity have small effects on fatigue. Instead, factors outside the direct effects of rheumatoid arthritis, such as obesity, physical inactivity, sleep disturbance, and depression, explain the majority of variation in fatigue. Some of these factors may be indirect effects of disease (e.g. pain can lead to sleep disturbance). Rheumatoid arthritis has significant effects on the quality of life of individuals with rheumatoid arthritis. The most effective approaches to reducing rheumatoid arthritis fatigue appear to be behavioral, such as increasing physical activity, or cognitive, such as cognitive behavioral interventions.

SUMMARY

Fatigue in rheumatoid arthritis appears to be largely because of factors outside the direct effects of the disease, such as behavioral and psychological factors. In spite of the tremendous impact of fatigue on patient health and quality of life, effective treatments remain elusive, but existing data show that behavioral and cognitive approaches may be most effective.

Associations of perceived social support and positive psychological resources with fatigue symptom in patients with rheumatoid arthritis

Objective

This study aimed to assess the association between perceived social support (PSS) and fatigue and the roles of hope, optimism, general self-efficacy and resilience as mediators or moderators on PSS-fatigue association among Rheumatoid Arthritis (RA) patients in China.

Methods

A multi-center, cross-sectional study was conducted withinpatients diagnosed with RA in northeast China, in which 305 eligible inpatients were enrolled. The Multidimensional Fatigue Inventory, Multidimensional Scale of Perceived Social Support, Herth Hope Index, Life Orientation Test Revised, General Self-Efficacy Scale and Ego-Resiliency Scale were completed. The associations of PSS, hope, optimism, general self-efficacy and resilience with fatigue and the moderating roles of these positive psychological constructs were tested by hierarchical linear regression. Asymptotic and resampling strategies were utilized to assess the mediating roles of hope, optimism, general self-efficacy and resilience.

Results

The mean score of the MFI was 57.88 (SD = 9.50). PSS, hope, optimism and resilience were negatively associated with RA-related fatigue, whereas DAS28-CRP was positively associated. Only resilience positively moderated the PSS-fatigue association (B = 0.03, β = 0.13, P<0.01). Hope, optimism and resilience may act as partial mediators in the association between PSS and fatigue symptoms (hope: a*b = -0.16, BCa 95%CI: -0.27, -0.03; optimism: a*b = -0.20, BCa 95%CI: -0.30, -0.10; resilience: a*b = -0.12, BCa 95%CI: -0.21–0.04).

Conclusions

Fatigue is a severe symptom among RA patients. Resilience may positively moderate the PSS-fatigue association. Hope, optimism and resilience may act as partial mediators in the association. PSS, hope, optimism and resilience may contribute as effective recourses to alleviate fatigue, upon which PSS probably has the greatest effect.
