Fatigue in Rheumatoid Arthritis Patients: Association With Sleep Quality, Mood Status, and Disease Activity

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.

A cross-sectional study of multidimensional fatigue in biologic-treated rheumatoid arthritis: which variables play a role?

PURPOSE

Despite efficient biological disease-modifying antirheumatic drugs (bDMARDs) Rheumatoid Arthritis (RA) patients still suffer from high fatigue. This study aims to further our knowledge by assessing severity levels of the various fatigue dimensions and their associations with pain, sleep quality, and psychological well-being in bDMARDs treated RA patients.

MATERIAL AND METHODS

The sample consisted of 146 RA patients (84.9% females; mean age 56.6 ± 13.6 years), who completed the MFI-20, SF-36, PSQI, GAD-7 and PHQ-9. Correlation analyses and multiple linear regressions were used to analyse the data.

RESULTS

General fatigue was the highest reported type of fatigue, followed by physical fatigue dimensions. In the final regression model, pain and disability were significantly associated with physical fatigue (p ≤ 0.001, p ≤ 0.05, respectively) and reduced activity (p ≤ 0.01, p ≤ 0.05, respectively). Anxiety was significantly associated with mental fatigue (p ≤ 0.05) and reduced motivation (p ≤ 0.01). Regression analyses showed no significant associations between depression, sleep quality, and fatigue in any of the final models.

CONCLUSIONS

Our findings indicate that effectively addressing fatigue in RA patients requires an individualized approach. This approach should acknowledge the varying degrees of fatigue across different fatigue dimensions (physical or mental), while also taking into account the patient's mental health problems, pain levels, and disability levels.

The Link between the Demographic and Clinical Factors and Fatigue Symptoms among Rheumatoid Arthritis Patients

Rheumatoid arthritis (RA) is a chronic systemic disease of connective tissue with periods of exacerbation and remission. Fatigue is excessive strain throughout the body that is disproportionate or unrelated to an activity or lifestyle. Fatigue is an integral part of RA in most patients. The study aimed to assess the level of fatigue in RA patients and establish the relationship between fatigue and demographic and clinical factors. The study group consisted of 128 RA patients according to European League Against Rheumatism (EULAR) criteria. The Functional Assessment of Chronic Illness Therapy-Fatigue and -Medical Outcomes Study Short Form 36 (SF-36) vitality scores were used to assess the severity of fatigue symptoms. The analyzed variables were gender, age, disease duration, education, marital status, place of residence, work and residence status, pharmacological treatment, pain, morning stiffness, hemoglobin, C-reactive protein (CRP), rheumatoid factor (RF), compression soreness, Richie Articular Index, and DAS28 disease activity. The examined patients experience chronic fatigue-the mean value on the FACIT-F scale was 24.1 ± 9.1 points and on the SF-36 Vitality score was 14.2 ± 1.8 points. There is a relationship between the level of fatigue and pain, long-lasting morning stiffness, active disease, increased soreness of joints, and low hemoglobin values. When analyzing the symptom of fatigue, each patient should be approached individually, using the existing questionnaires or asking key questions to recognize the situation. The presence of fatigue symptoms should be considered during therapy and patient care by searching for and eliminating additional, intensifying stimuli and increasing its level.

Screening for depressive symptoms in patients with rheumatoid arthritis: relationship with pain severity, disease activity, and sleep quality

Background

Rheumatoid arthritis (RA) is an autoimmune systemic condition that primarily affects all synovial joints, eventually leading to deformity and clinical disability. Much progress has been made in the evaluation of inflammation and disease activity in recent years; however, other factors that can influence these patients’ quality of life, including depression, stress, fatigue, sleep problems, fibromyalgia, sexual activity, and obesity, are often not evaluated by rheumatologists. Our purpose was to explore depressive symptoms in patients with RA and determine how they connected to other aspects of the disease, including pain severity, disease activity, and sleep quality.

Results

A cross-sectional study including 1200 patients with RA was performed. Paints with RA were classified into two groups based on the presence or absence of depressive symptoms using the Beck Depression Inventory-II (BDI-II). Group 1 included patients with both RA and depressive symptoms of varying severity; group 2 included patients with RA but without depressive symptoms. The patients underwent clinical evaluation and application of the Pittsburgh Sleep Quality Index (PSQI), Health Assessment Questionnaire for pain (HAQ-pain), and the Multidimensional Assessment of Fatigue scale (MAF). RA disease activity was evaluated using the DAS28 score. Depressive symptoms of varying severity were prevalent in 96% of our patients with RA, of whom 43.3% had minimal depression, while 13.7% had severe depression. The RA group with depression had a longer duration of disease, prolonged morning stiffness, and high disease activity measured by the DAS28 score than patients with only RA. In RA patients with concomitant depression, pain, sleep, and fatigue scores were also worse.

Conclusions

The presence of depression among patients with RA was associated with worse DAS28, HAQ, PASQI, and fatigue scores. Screening and recognition of such psychosocial disorders may help patients achieve optimal disease control and a good outcome.

Fatigue and Associated Factors in an Immune-Mediated Inflammatory Disease Population: A Cross-Sectional Study

Fatigue is a main symptom of chronic diseases, including immune-mediated inflammatory diseases (IMIDs), such as inflammatory bowel disease (IBD) and inflammatory arthritis (IA); however, the pathophysiological mechanisms are not completely understood. The aim of this study was to assess the prevalence of fatigue and the associated factors in an IMIDs population. A control group, IBD, and IA patients, were enrolled. The PROMIS® fatigue questionnaire was used to evaluate the symptoms. Information on demographics, anthropometrics, disease characteristics, and medications was collected for each participant. A total of 471 subjects (137 with IBD, 103 with IA, and 206 controls) were enrolled. IBD and IA patients reported greater fatigue than controls (p < 0.001, each). In univariate regression, patients with anxiety and depression were more likely to report fatigue (p = 1.40 × 10−9 and p = 3.80 × 10−11, respectively). Males, holding a high school diploma, and being employed were inversely correlated to the domain (p = 1.3 × 10−5; p = 0.003 and p = 0.005, respectively). The use of steroids and disease activity determined increased fatigue (p = 0.014 and p = 0.019; respectively). In the multivariate analysis, anxiety and depression remained associated (p = 0.002 and p = 1.3 × 10−5, respectively). IMIDs patients present increased fatigue compared with healthy subjects. Anxiety and depression are the main associated factors, suggesting a psychological component of the symptom; thus, a holistic management should be established.

Correlation of Depression and Anxiety With Rheumatoid Arthritis

Background

Psychiatric comorbidity with a chronic disease is linked with poor patient outcomes. Therefore, the current research assessed the correlation of rheumatoid arthritis (RA) with depression and anxiety disorders. 

Methodology

A prospective observational study was undertaken at a public sector hospital between December 2020 to June 2021. All individuals who presented with rheumatoid arthritis were included in the study. A healthy cohort acted as the control group. Depression and anxiety were assessed using the Hamilton depression rating scale (HDRS) and the Hamilton anxiety rating scale (HAM-A), respectively. The patients were inquired about their gender, age, and duration of RA. Further stratification was done using the Chi-squared test. A p-value of <0.05 was decided as the cut-off for significance. All data from the patients were collected in a predefined pro forma. 

Results

A total of 169 patients with RA and 85 healthy controls were enrolled in the study. The mean depression score among patients with RA was 19.65 ± 1.44 versus 14.4 ± 1.31 in the control group (p<0.001). Moreover, the mean anxiety score in patients with RA was 19.44 ± 2.4. About 71% of patients with RA were diagnosed with psychiatric issues, while only 7.1% of individuals in the control group had either depression or anxiety (p<0.0001). Furthermore, it was found that the majority of the patients with RA had depression with a frequency of 70 (58.3%), while only six participants in the control group had depression. None of the participants had moderate or severe depression. However, 16 (69.6%) patients with RA had major anxiety issues. In 27 patients, mixed anxiety-depression disease was diagnosed. Out of these, 23 (85.2%) had the depression-dominant mixed disorder. 

Conclusion

The present study highlighted the alarming incidence of depression and anxiety among patients with RA. Furthermore, it also indicated the relationship between severity of psychiatric comorbidity with chronic rheumatoid arthritis in our population. Further large-scale studies are needed to ascertain the demographic confounders that may help predict psychiatric disorders among patients with RA. 

A comparative study between rheumatoid arthritis and osteoarthritis regarding association of insomnia with disease status

Background

Sleep disturbance is closely related to inflammation and pain. Good sleep quality is essential for patients’ psychological and physical states as well as their quality of life. The aim of this study was to detect how insomnia as a major sleep disturbance could add to the disease burden in rheumatoid arthritis (RA) and osteoarthritis patients (OA) and to determine the predictor parameters in each of them in order to orient the rheumatologist to this unnoticed symptom that could adversely affect the patients’ life. This study included: 20 RA patients, 20 primary knee OA patients together with 20 healthy controls. RA disease activity was assessed by the disease activity score (DAS-28). All participants were assessed for sleep disturbances by the Athens Insomnia Scale, quality of life (QoL) using the short form QoL (SF-36 QoL) scale, depression by the Beck depression inventory (BDI), and functional disability by the Health Assessment Questionnaire Disability Index (HAQ-DI). OA patients were assessed by the Knee OA Flare Up Score (KOFUS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Radiological evaluation for RA patients was done by the Simple Erosion Narrowing Score, while the Kellgren and Lawrence (K-L) radiological grading system was used for OA patients.

Results

Insomnia was found in 75% of the studied RA patients, 25% of the studied OA patients and none of the healthy control with significant difference (P < 0.001). Significant correlations of the insomnia scale with the number of tender and swollen joints (r = 0.66, 0.76 respectively and p = 0.001 both), DAS-28 (r = 0.71, P < 0.001), anti-CCP antibodies titre (r = 0.53, p = 0.02) and the BDI (r = 0.65, p = 0.002) among RA patients were found. Correlations among OA patients occurred with morning stiffness duration (r = 0.69, P = 0.001), number of affected joints (r = 0.81, P = 0.001), the BDI scale (r = 0.51, P = 0.02), the WOMAC index (r = 0.57, P = 0.009), the KOFUS score (r = 0.76, p < 0.001) and the K-L score (r = 0.67, P = 0.001). Linear regression analysis indicated that the predictors for insomnia in RA were DAS-28 and the BDI, while in OA were the number of affected joints and the KOFUS score.

Conclusions

Insomnia is a disease burden especially in RA patients being one of the leading causes of depression and is greatly affected by the disease activity. In general the burden of insomnia is much less in OA except in severe cases with markedly affected joints. Rheumatologists should be aware of this disorder that could affect patients’ health, mood, and functional activity.

Association of lifestyle and disease characteristics with self-rated wellness/health score in patients with rheumatoid arthritis

Objective

To study the relationship of self-rated wellness/health and lifestyle in patients with rheumatoid arthritis.

Methods

Self-rated wellness/health, demographics, smoking, mood, sleep, physical activity, diet, symptoms/signs, body mass index and laboratory findings in 142 patients with rheumatoid arthritis were collected in the current cross-sectional study. Multivariable generalized additive model (GAM) was employed to study the association of self-rated wellness/health score and lifestyle factors.

Results

Female/male ratio was 116/26 and the mean (SD) age of sample was 52 (13) years. Mean (SD) self-rated wellness/health score out of 10 was 7.2 (1.63). Mean (SD) number of tender joints and swollen joints were 4.42 (4.55) and 4.00 (4.26), respectively. The mean sleep score was 29.5 out of 70. Patients went to bed more than one hour earlier during the weekdays compared to weekends (22:45 vs. 23:52 PM, respectively, p < 0.0001). They also woke up more than one hour earlier during the weekdays compared to the weekends (6:08 vs. 7:20 AM, respectively, p < 0.0001). Their nap duration during weekdays was about half an hour shorter than the nap duration on weekends (19.75 vs. 48.02 minutes, respectively, p < 0.0001). The mean mood and diet scores were 18.5/35 and 22.5/42, respectively. By backward elimination in multivariable regression model (GAM), disease duration, mood, sleep quality, weekdays sleep characteristics (sleep duration, time to go to bed, wake-up time, time to fall asleep and nap duration), and sleep duration on weekends remained in the final model (R² = 0.225, p = 0.01). Sleep quality, nap duration on weekdays, night sleep duration on weekends and mood status were the significant variables associated with self-rated wellness/health score.

Conclusion

In patients with rheumatoid arthritis, the low self-rated wellness/health score was associated with the low sleep quality, long sleep duration on weekends, and long nap duration on weekdays.

The effect of progressive muscle relaxation on sleep quality and fatigue in patients with rheumatoid arthritis: A randomized controlled trial

AIMS

The aim of this study was to investigate the effects of progressive muscle relaxation on sleep quality and fatigue in patients with rheumatoid arthritis.

METHODS

This randomized controlled study was conducted with 72 patients with rheumatoid arthritis who applied to the rheumatology outpatient clinic of a university hospital between January and May 2018. The data were collected using the Patient Information Form, Pittsburgh Sleep Quality Index and Fatigue Severity Scale. After the patients in the intervention group completed the forms, patients were given training with regard to the application of progressive muscle relaxation which they subsequently performed, and the Pittsburgh Sleep Quality Index and Fatigue Severity Scale forms were repeated after 6 weeks.

RESULTS

After performing progressive muscle relaxation for 6 weeks, the total score of the Pittsburgh Sleep Quality Index and the fatigue score decreased among patients in the intervention group; no change was observed among the patients in the control group. A statistical difference was found between the two groups in terms of the Pittsburgh Sleep Quality Index's and Fatigue Severity Scale's mean scores.

CONCLUSION

Progressive muscle relaxation can be recommended to enhanced sleep quality and reduce fatigue in patients with rheumatoid arthritis.

A biopsychosocial network model of fatigue in rheumatoid arthritis: a systematic review

Fatigue in RA is prevalent, intrusive and disabling. We propose a network model of fatigue encompassing multiple and mutually interacting biological, psychological and social factors. Guided by this model, we reviewed the literature to offer a comprehensive overview of factors that have been associated with fatigue in RA. Six categories of variables were found: physical functioning, psychological functioning, medical status, comorbidities and symptoms, biographical variables and miscellaneous variables. We then systematically reviewed associations between fatigue and factors commonly addressed by rheumatology health professionals. Correlations of fatigue with physical disability, poor mental well-being, pain, sleep disturbance and depression and anxiety were ∼0.50. Mostly these correlations remained significant in multivariate analyses, suggesting partly independent influences on fatigue and differences between individuals. These findings indicate the importance of research into individual-specific networks of biopsychosocial factors that maintain fatigue and tailored interventions that target the influencing factors most relevant to that person.
