Sleep and rheumatic diseases

Sleep Disorders in Connective Tissue Diseases-Coexisting Diseases or Disease Components?

This comprehensive review examines the complex relationship between sleep disorders and rheumatic diseases, supported by findings from the latest research articles. It encompasses various rheumatic conditions, including rheumatoid arthritis, systemic lupus erythematosus, and systemic sclerosis. The review reveals the bidirectional relationship between sleep disorders and these diseases, emphasizing their impact on disease progression and quality of life. Conventional and alternative therapeutic interventions for connective tissue diseases are presented, focusing on improving sleep quality and alleviating rheumatic symptoms. The role of pro-inflammatory cytokines and their potential modulation through pharmacological agents is also discussed. In the treatment of sleep disorders, various options are proposed, such as cognitive behavioral therapy for insomnia, physical activity, dietary modifications, and alternative approaches like reflexology and acupuncture. Thus, this review offers a nuanced understanding of the connection between sleep disorders and rheumatic diseases, supported by evidence from diverse studies. Such an approach is particularly important because it enhances sleep quality for overall patient well-being in the holistic management of rheumatic conditions.

A concept elicitation study to understand the relationship between sleep and pain in rheumatoid arthritis and axial spondyloarthritis

PURPOSE

This qualitative study (GSK study: 213635) was designed to better understand sleep disturbance as experienced by individuals with rheumatoid arthritis (RA) or axial spondyloarthritis (axSpA), and the relationship between sleep disturbance and pain and other aspects of the disease and disease activity.

METHODS

Sixty-minute, one-on-one, concept elicitation interviews were conducted with 30 participants (15 with RA and 15 with axSpA) from the US. Interviews were audio-recorded and transcribed verbatim. Interview transcripts were coded and analyzed to explore themes related to pain and sleep disturbance, and relationships among those themes.

RESULTS

Pain was a prominent driver of sleep disturbance; 12 participants with RA (80%) and 14 with axSpA (93%) reported that pain impacted their ability to fall asleep, while all 15 with RA (100%) and 14 with axSpA (93%) reported that pain impacted their ability to stay asleep. Two-thirds of participants with RA (67%) or axSpA (60%) described a bi-directional relationship, whereby pain worsened sleep disturbance and sleep disturbance further aggravated pain. Factors other than pain, such as fatigue and emotional health, were also reported as important contributors to sleep disturbance (RA: n = 12/15, 80%; axSpA: n = 14/15, 93%). Participants with RA or axSpA described complex interconnections between fatigue, emotional health, pain, and sleep, often labeling these relationships as "vicious cycles". Notably, half of all participants reported sleep disturbance occurring without pain or other understood causes.

CONCLUSION

These perspectives collected from people with RA or axSpA suggest that reducing sleep disruption directly may offer clinically relevant benefits.

Effects of yoga on depressive symptoms, anxiety, sleep quality, and mood in patients with rheumatic diseases: Systematic review and meta-analysis

OBJECTIVE

To investigate the effects of yoga on depressive symptoms, anxiety, sleep quality, and mood of patients with rheumatic diseases through a systematic literature review with meta-analysis.

LITERATURE SURVEY

This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement and the Cochrane recommendations and risk of bias tool. The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO). Studies were selected using the PICOS (participants, intervention, comparison, outcome, and study) strategy. Searches were carried out until March 2022 and performed in Web of Science, PubMed, SportDiscus, Scopus, Cochrane, and EBSCO databases.

METHODOLOGY

Data were extracted to identify the differences between yoga and control and exercise groups and effect sizes.

SYNTHESIS

In total, 27 studies were included for qualitative analysis and 18 for meta-analysis. The studies found investigated yoga in patients with osteoarthritis, fibromyalgia, rheumatoid arthritis, and chronic fatigue syndrome. Regarding the risk of bias, the majority of studies showed a high risk or uncertain risk of bias in several criteria. Regarding the meta-analysis, yoga was favored to decrease depressive symptoms (standard mean difference [SMD]:-0.88; 95% confidence interval [CI]:-1.42; -0.34), anxiety (SMD: -0.51; 95% CI = -0.81 to -0.20), and improve sleep quality SMD = -0.96; 95% CI = -1.36 to -0.56). No differences were found between yoga and other exercise modalities in depression (p < .01).

CONCLUSIONS

Yoga is effective in improving depression, anxiety, and sleep quality of patients with rheumatic diseases. However, research in this field still needs further studies, because of methodological issues in the studies and a reduced number of studies conducted on each rheumatic disease and on the effects of yoga on each variable.

Subjective sleep quality and fatigue assessment in Polish adult patients with primary immunodeficiencies: A pilot study

Introduction

Primary immunodeficiencies (PIDs) are clinically heterogeneous disorders caused by abnormalities in the immune system. However, PIDs are genetically determined and may occur at any age from early childhood to elderly age. Due to chronic patterns, the risk of malignancy and organ damage in patients with PIDs may affect any aspect of life, including sleep patterns. To our knowledge, the prevalence of insomnia and subjective sleep quality have not been investigated in patients with PIDs. Therefore, this pilot study was conducted to investigate sleep quality, the prevalence of sleep disturbances, and fatigue in adult patients with PIDs in Poland.

Methods

All participants were surveyed using the Athens Insomnia Scale, Pittsburgh Sleep Quality Index, Fatigue Severity Scale, and a questionnaire concerning general health and demographic data. We included 92 participants: 48 women (52.2%) and 44 men (47.8%).

Results

Participants' mean age was 41.9 ± 13.9 years. The mean sleep duration was 7.0 ± 1.5 hours, and the mean sleep latency was 41.2 ± 53.1 minutes. Additionally, 44.6% of patients (n=41) had symptoms of insomnia and 44.6% (n=42) had poor sleep quality. Less than one-fourth (n=22; 23.9%) of the patients reported the use of sleeping pills; moreover, clinically significant fatigue was reported in 52.2% (n=48).

Discussion

Our investigation provides insight into the problem of sleep disturbances in patients with PIDs. Data have demonstrated that sleeping disorders with concomitant fatigue are common in patients with PID. Further studies are needed to determine the determinants of poor sleep quality in this specific group of patients.

Prevalence and Risk Factors of Depression in Patients with Rheumatic Disease in South Korea during the COVID-19 Pandemic

This study aimed to examine the prevalence and risk factors of depression among patients with rheumatic diseases (RDs) during the coronavirus disease 2019 (COVID-19) pandemic. This study adopted a cross-sectional design, and 160 outpatients with RDs in one university hospital in South Korea were sampled using the convenience sampling method. Data were collected from May to July 2021 using a structured questionnaire. The risk factors of depression were analyzed using descriptive statistics and multiple logistic regression analyses. The prevalence rates of post-traumatic stress disorder (PTSD), insomnia, and depression were 37.5%, 20.0%, and 24.4%, respectively. Multiple logistic regression analyses confirmed that employment status, monthly income, perceived health, PTSD, and insomnia were significant risk factors of depression. The findings highlight the urgent need to assist patients with RDs who are at risk of depression during the COVID-19 pandemic, especially individuals who are unemployed or have low incomes and poor perceived health, individuals with high PTSD, and individuals with severe insomnia. There is a need to provide disease-specific interventions to effectively alleviate depression among these individuals during the COVID-19 pandemic.

An Apriori Algorithm-Based Association Analysis of Analgesic Drugs in Chinese Medicine Prescriptions Recorded From Patients With Rheumatoid Arthritis Pain

Chronic pain, a common symptom of people with rheumatoid arthritis, usually behaves as persistent polyarthralgia pain and causes serious damage to patients' physical and mental health. Opioid analgesics can lead to a series of side effects like drug tolerance and addiction. Thus, seeking an alternative therapy and screening out the corresponding analgesic drugs is the key to solving the current dilemma. Traditional Chinese Medicine (TCM) therapy has been recognized internationally for its unique guiding theory and definite curative effect. In this study, we used the Apriori Algorithm to screen out potential analgesics from 311 cases that were treated with compounded medication prescription and collected from “Second Affiliated Hospital of Zhejiang Chinese Medical University” in Hangzhou, China. Data on 18 kinds of clinical symptoms and 16 kinds of Chinese herbs were extracted based on this data mining. We also found 17 association rules and screened out four potential analgesic drugs—“Jinyinhua,” “Wugong,” “Yiyiren,” and “Qingfengteng,” which were promised to help in the clinical treatment. Besides, combined with System Cluster Analysis, we provided several different herbal combinations for clinical references.

Physical and Psychosocial Burden of Psoriatic Arthritis: Longitudinal Data From a Population-Based Study in Norway

OBJECTIVE

Psoriatic arthritis (PsA) can have a significant impact on health-related quality of life (HRQoL). Data on the timing of changes in the HRQoL of patients with PsA are limited. The present study was undertaken to explore associations between sleep disturbance, fatigue, pain, anxiety, depression, general health status, and satisfaction with life before and after a diagnosis of PsA compared to the general population.

METHODS

Patients diagnosed with PsA between the Nord-Trøndelag Health Study (HUNT2 [1995-1997] and HUNT3 [2006-2008]) surveys were compared to the general population. The adjusted odds ratio (OR_adj ) with 95% confidence interval (95% CI) was estimated at both time points.

RESULTS

Among 36,507 individuals participating in both the HUNT2 and HUNT3 surveys, 160 were diagnosed with PsA between the surveys. The prevalence of sleep disturbances and fatigue was higher in PsA patients after diagnosis compared to the general population (OR_adj 2.24 [95% CI 1.55-3.25] and OR_adj 1.94 [95% CI 1.27-2.98], respectively). The prevalence of pain and poor health status were higher in patients with PsA compared with the general population even before PsA was diagnosed (OR_adj 2.81 [95% CI 1.96-4.02] and OR_adj 3.08 [95% CI 2.19-4.35], respectively) and increased after diagnosis of PsA (OR_adj 12.87 [95% CI 6.27-26.40] and OR_adj 5.63 [95% CI 3.99-7.95], respectively). For anxiety, depression, and life satisfaction, patients who developed PsA were comparable to the general population both before and after the diagnosis of PsA.

CONCLUSION

Compared to the general population, PsA patients reported a higher prevalence of pain and poorer health status before diagnosis. Increased prevalence of sleep disturbances and fatigue in PsA patients was only found after the PsA diagnosis, and no differences between patients with PsA and the control group were found for anxiety and depression.

Psoriatic arthritis: exploring the occurrence of sleep disturbances, fatigue, and depression and their correlates

Introduction

Sleep disturbances, fatigue, and anxiety/depression in psoriatic arthritis (PsA) may be influenced by skin and musculoskeletal manifestations. All of these in turn affect the psychosocial impact of disease. The objective was to explore the occurrence of sleep disturbances, fatigue, and anxiety/depression in psoriatic arthritis (PsA) patients, and their correlates.

Methods

A broad data collection was performed in 137 Norwegian PsA outpatient clinic patients including demographics, disease activity measures for both skin and musculoskeletal involvement, and patient-reported outcome measures. Sleep disturbances and fatigue were defined present if the numeric rating scale (0–10) score was ≥ 5. Anxiety/depression was assessed using a questionnaire (1–3; 1 defined as no anxiety/depression). Descriptive statistics was applied, and associations were explored using univariate and adjusted linear regression analysis.

Results

The mean age was 52.3 years, PsA disease duration 8.8 years; 49.6% were men and 54.8% were currently employed/working. The prevalence of sleep disturbances was 38.0%, fatigue 44.5%, and anxiety/depression 38.0%. In adjusted analysis, pain, fatigue, and higher mHAQ were associated with sleep disturbances. Sleep disturbances, pain, and anxiety/depression were associated with fatigue, whereas only fatigue was associated with anxiety/depression.

Conclusions

The prevalence of sleep disturbances, fatigue, and anxiety/depression was frequently reported by PsA patients. No measures reflecting skin involvement or objective measures of musculoskeletal involvement were independently associated with sleep disturbances, fatigue, or anxiety/depression. Our data suggest that patients’ perceptions of musculoskeletal involvement (pain or mHAQ) play an important role causing sleep disturbances and fatigue, whereas fatigue in PsA patients is strongly associated with anxiety/depression.
