Rheumatoid arthritis, cardiovascular disease and physical exercise: a systematic review

Managing rheumatoid arthritis and cardiovascular disease: the role of physical medicine and rehabilitation

INTRODUCTION

Cardiovascular disease (CVD) presents a significant challenge in rheumatoid arthritis (RA), a systemic chronic ailment affecting the joints and causing systemic inflammation. Effective RA management, including pharmacological and non-pharmacological interventions, is crucial for mitigating cardiac risk. Pharmacotherapy, though effective, can have adverse effects, leading many patients to seek complementary therapies. This study investigates the impact of physical medicine and rehabilitation on RA management in patients with cardiovascular disease, analyzing clinical data to assess the efficacy of integrated therapeutic approaches.

METHODS

This retrospective monocentric study draws upon data from patient records at the Rheumatology Department of the Regional Clinical Hospital of Shymkent, Kazakhstan, spanning 2019 to 2022. Data collected included demographic information, diagnoses, comorbidities, medical anamneses, lab results, and treatment regimens, including physical medicine and rehabilitation interventions. Data were summarized in Microsoft Excel. Statistical analysis was performed using IBM SPSS Statistics (version 26.0).

RESULTS

An analysis of 350 patients with RA identified 143 cases of concomitant CVD, with arterial hypertension being the most common cardiovascular disease. The prevalence of CVD among patients with RA was 40%, with a mean age of 58 years, peaking between 50 and 65 years. The majority of patients were women. A strong association was found between increased RA activity and elevated cardiovascular risk. Despite the widespread use of glucocorticosteroid therapy, rehabilitation coverage remained limited. A significant proportion of patients had elevated cholesterol and C-reactive protein levels, while those who engaged in physical therapy and rehabilitation had lower cholesterol levels. Comparative analysis of yoga integration into rehabilitation programs for patients with RA, alongside other modalities (kinesiotherapy, balneotherapy, and pilates), showed that yoga participants exhibited lower pain levels, reduced morning stiffness duration, and lower mean DAS-28 scores compared to those using alternative rehabilitation methods.

CONCLUSION

Integrating physical medicine and rehabilitation, particularly yoga, with pharmacological treatments appears promising for improving patient outcomes. Yoga has demonstrated benefits in reducing pain, morning stiffness, and disease activity. Continued research is essential to refine these approaches and enhance RA and CVD management in patients.

Consensus statement of Chinese experts on exercise prescription (2023)

Exercise prescriptions play a vital role in the prevention and treatment of chronic diseases. A consensus regarding exercise prescription is important for physical health. The "Consensus statement of Chinese experts on exercise prescription" (hereinafter referred to as "Expert Consensus") divides exercise prescription into two categories: fitness exercise prescription and medical exercise prescription. Traditional Chinese fitness exercises, exercise risk, exercise prescription, and basic precautions for exercise prescription are explained.

The Effects of Exercise Training on Functional Capacity and Quality of Life in Patients with Rheumatoid Arthritis: A Systematic Review

Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation. The purpose of this systematic review is to evaluate the effectiveness of exercise training on functional capacity and quality of life (QoL) in patients with RA. We performed a search in four databases, selecting clinical trials that included community or outpatient exercise training programs in patients with RA. The primary outcome was functional capacity assessed by peak VO2 or the 6 min walking test, and the secondary outcome was QoL assessed by questionnaires. Seven studies were finally included, identifying a total number of 448 patients. The results of the present systematic review show a statistically significant increase in peak VO2 after exercise training in four out of seven studies. In fact, the improvement was significantly higher in two out of these four studies compared to the controls. Six out of seven studies provided data on the patients' QoL, with five of them managing to show statistically significant improvement after exercise training, especially in pain, fatigue, vitality, and symptoms of anxiety and depression. This systematic review demonstrates the beneficial effects of exercise training on functional capacity and QoL in patients with RA.

Do physical therapists follow evidence-based practices for treatment of inflammatory arthritis? Results from an online survey

BACKGROUND

Physical therapists (PTs) should know how to best treat patients with inflammatory arthritis.

OBJECTIVE

To document interventions chosen by PTs for patients with rheumatoid arthritis (RA) and ankylosing spondylitis (AS) and whether choices follow evidence-based practice.

METHODS

Licensed musculoskeletal PTs in Quebec, Canada responded to an online survey. Descriptive statistics illustrated proportions for each treatment choice and inferential statistics explored associations with demographic and practice-related factors.

RESULTS

There were 298 PTs who responded to the survey. For both RA and AS respectively, most common interventions were mobility exercises (91.0%; 98.3%) and patient education (90.1%; 92.8%). For both cases, slightly >60% selected strengthening exercises. Passive forms of therapy were chosen by 36% of PTs for RA and 58% for AS. Aerobic exercise was rarely selected. PTs working in the public sector were less likely to use manual therapy for both RA (Odds Ratio (OR) 0.43, 95% confidence interval (CI) 0.22,0.86) and AS (OR 0.46, 95% CI 0.22,0.97).

CONCLUSIONS

Most PTs chose mobility exercises and patient education, representing evidence-based approaches. Despite current recommendations, strengthening and especially aerobic exercises were not used as much. There is a need to increase awareness regarding the benefits of strengthening and aerobic exercise for these patients.

Tailoring Strength Training Prescriptions for People with Rheumatoid Arthritis: A Scoping Review

Introduction: Prescribing strength training (ST) for people with rheumatoid arthritis (RA) is complicated by factors (barriers and facilitators) that affect participation. It is unclear whether guidelines include recommendations beyond prescription parameters (frequency, intensity, time, type, volume, and progression) and adequately incorporate participation factors tailored to people with RA. Objective: To summarize available recommendations to aid in the tailoring of ST prescriptions for people with RA. Methods: Medline, Embase, and CINAHL databases and gray literature were searched for guidelines, recommendations, and review articles containing ST prescription recommendations for RA. Article screening and data extraction were performed in duplicate by two reviewers. Results: Twenty-seven articles met the inclusion criteria. The recommendations address RA-specific ST participation factors including: knowledge gaps (of equipment, ST benefits, disease), memory problems, the management of joint deformity, comorbidity, the fluctuating nature of the disease and symptoms (pain, stiffness, flares), fear avoidance, motivation, need for referral to other professionals, and provision of RA-specific resources. Conclusion: This review summarizes recommendations for tailoring ST prescriptions for people with RA. Future research is required to understand how pain, symptom assessment, and unaddressed ST participation factors like sleep and medication side effects can be addressed to support ST participation amongst people with RA.

'I never thought exercise could help improve my sleep': experiences of people with rheumatoid arthritis on the impact of an 8-week walking-based exercise intervention in improving their sleep

Objective

The purpose of this study was to explore the experiences of people with RA of participating in an exercise intervention to improve their sleep.

Methods

Using a qualitative descriptive design, semi-structured face-to-face interviews were conducted with 12 people with RA who had completed an 8-week walking-based exercise intervention to improve their total sleep time, sleep quality and sleep disturbance. Data were analysed using thematic analysis.

Results

Four themes were generated: positive impact of exercise on participants' sleep ('I really didn't think any type of exercise would help me sleep better, if I'm honest'); positive experiences of the exercise intervention ('I learnt so much regarding walking that I didn't even think about'); clear mental health benefits ('If you don't sleep well then it will have a knock-on effect to your mental health'); and achieving empowerment and ownership when exercising ('I feel empowered now and confident that I'm not doing harm to myself').

Conclusion

The findings demonstrated that participants had not expected exercise to improve their sleep. Although there is a growing consensus that exercise will benefit sleep and mitigate some disease symptoms, research is severely lacking in people with RA.

Effects of Aerobic and Resistive Exercise on Muscle Measurements and Body Composition in Female Patients With Rheumatoid Arthritis

OBJECTIVE

This study aimed to show the effects of different exercise types on disease activity, pain, functional status, and quality of life in female patients with rheumatoid arthritis with low disease activity or in remission and supported these findings with body composition and muscle measurements.

DESIGN

This randomized controlled prospective study screened female patients aged 20-50 years with rheumatoid arthritis. The patients were randomized into 12-wk resistance exercise, aerobic exercise, and control groups.

RESULTS

The mean age of the 66 patients was 42.5 ± 5.6 yrs. In the resistance and aerobic exercise groups compared with the control group, a positive significant difference was found in the pain, disease activity, several subparameters of quality of life, M. gastrocnemius, and M. biceps femoris muscle thickness measurements, and fat mass in the lower limbs before and after treatment ( P < 0.05). Compared with the other groups, the resistance exercise group showed a significant improvement in M. rectus femoris and M. vastus intermedius muscle thickness measurements, whole body fat mass, whole body and lower extremity lean body mass, and timed up and go test when comparing before and after treatment ( P < 0.05).

CONCLUSIONS

In rheumatoid arthritis patients, resistance exercises led to a significant increase in muscle thickness, functional status, lean body mass compared with other exercises; resistance exercises also resulted in a significant reduction in pain and disease activity.

Effects of an Exercise Program and Cold-Water Immersion Recovery in Patients with Rheumatoid Arthritis (RA): Feasibility Study

Rheumatoid Arthritis (RA) patients present is an increased cardiovascular risk (CVR) linked to systemic inflammatory manifestations. A physical activity program with known positive effects on CVR, followed by cryotherapy because of its analgesic and anti-inflammatory effects, may be interesting. However, there are no reports in the literature of such a program. This study aimed to determine the feasibility (acceptability, safety, and effectiveness) of an individualized Intermittent Exercise Program followed by cold-water immersion as a recovery for RA patients. The program was conducted three times per week by eighteen RA patients (one man) with means of age and BMI of 55 (11.9) years and 25.5 (4.7) kg·m^-2. Outcomes were assessed before and after nine and seventeen sessions and included evaluation of acceptability by perceived exertion (Borg) and water temperature (VAS) measures at each session; safety by a number of painful and swollen joints (echography); physical function (health assessment questionnaire); general health status (Short Form-36) measures; and effectiveness by arterial stiffness (pulse wave velocity, or PWV) measures. The results showed good acceptability of the program; no patient dropped out of the protocol or even presented difficulties or perceived pain. The HR and PWV values decreased significantly (70.2 ± 8.4 to 66 ± 5.5; p < 0.05 and 8.9 ± 1.2 to 7.0 ± 0.8; p < 0.001) after nine exercise sessions. No aggravation of symptoms has been noted. This program is acceptable, safe, and effective; consider tailoring it for supervised home-based use.

Improved outcomes in rheumatoid arthritis with obesity after a weight loss intervention: randomized trial

OBJECTIVE

To examine whether a weight loss intervention programme improves RA disease activity and/or musculoskeletal ultrasound synovitis measures in obese RA patients.

METHODS

We conducted a proof-of-concept, 12-week, single-blind, randomized controlled trial of obese RA patients (BMI ≥ 30) with 28-joint DAS (DAS28)  ≥ 3.2 and with evidence of power Doppler synovitis. Forty patients were randomized to the diet intervention (n = 20) or control group (n = 20). Diet intervention consisted of a hypocaloric diet of 1000-1500 kcal/day and high protein meal replacements. Co-primary outcomes included change in DAS28 and power Doppler ultrasound (PDUS)-34. Clinical disease activity, imaging, biomarkers, adipokines and patient-reported outcomes were monitored throughout the trial. Recruitment terminated early. All analyses were based on intent-to-treat for a significance level of 0.05.

RESULTS

The diet intervention group lost an average 9.5 kg/patient, while the control group lost 0.5 kg (P < 0.001). Routine Assessment of Patient Index Data 3 (RAPID3) improved, serum leptin decreased and serum adiponectin increased significantly within the diet group and between the groups (all P < 0.03). DAS28 decreased, 5.2 to 4.2, within the diet group (P < 0.001; -0.51 [95% CI -1.01, 0.00], P = 0.056, between groups). HAQ-Disability Index (HAQ-DI) improved significantly within the diet group (P < 0.04; P = 0.065 between group). Ultrasound measures and the multi-biomarker disease activity score did not differ between groups (PDUS-34 -2.0 [95% CI -7.00, 3.1], P = 0.46 between groups).

CONCLUSION

Obese RA patients on the diet intervention achieved weight loss. There were significant between group improvements for RAPID3, adiponectin and leptin levels, and positive trends for DAS28 and HAQ-DI. Longer-term, larger weight loss studies are needed to validate these findings, and will allow for further investigative work to improve the clinical management of obese RA patients.

The role of microRNAs in regulating inflammation and exercise-induced adaptations in rheumatoid arthritis

MicroRNAs (miRNAs) are endogenously generated single-stranded RNAs that play crucial roles in numerous biological processes, such as cell development, proliferation, differentiation, metabolism and apoptosis. They negatively regulate target gene expression by repressing translation of messenger RNA into a functional protein. Several miRNAs have been implicated in the development and progression of RA. They are involved in inflammatory and immune processes and are associated with susceptibility to RA and disease activity. They are also considered to be potential markers of disease activity or even therapeutic targets. Likewise, several miRNAs are affected acutely by exercise and regulate exercise-related adaptations in the skeletal muscle and cardiovascular system and aerobic fitness. Interestingly, some miRNAs affected by exercise are also important in the context of RA. Investigating these might increase our understanding of the effects of exercise in RA and improve exercise prescription and, potentially, disease management. In this review, we focus on the miRNAs that are associated with both RA and exercise and discuss their roles in (and potential interactions between) RA and exercise-induced adaptations.

Inequity in exercise-based interventions for adults with rheumatoid arthritis: a systematic review

Objectives

This systematic review describes the extent to which PROGRESS-Plus equity factors were considered in the eligibility criteria of trials of exercise interventions for adults with RA.

Methods

Electronic databases were searched for published (Cinahl, Embase, Medline, Physiotherapy Evidence Database), unpublished (Opengrey) and registered ongoing (International Standard Randomized Controlled Trial Number registry) randomized controlled trials (RCTs) of exercise interventions for adults with RA. Two authors independently performed study selection and quality assessment (Cochrane risk of bias tool).

Results

A total of 9696 records were identified. After screening, 50 trials were included. All trials had either some concerns or high risk of bias and reported at least one PROGRESS-Plus equity factor within the eligibility criteria; this included place of residence, personal characteristics (age and disability), language, sex, social capital, time-dependent factors or features of relationship factors. Where reported, this equated to exclusion of 457 of 1337 potential participants (34%) based on equity factors.

Conclusion

This review identified the exclusion of potential participants within exercise-based interventions for people with RA based on equity factors that might affect health-care opportunities and outcomes. This limits the generalizability of results, and yet this evidence is used to inform management and service design. Trials need to optimize participation, particularly for people with cardiovascular conditions, older adults and those with cognitive impairments. Reasons for exclusions need to be justified. Further research needs to address health inequalities to improve treatment accessibility and the generalizability of research findings.

Metabolic Abnormalities, Cardiovascular Disease, and Metabolic Syndrome in Adult Rheumatoid Arthritis Patients: Current Perspectives and Clinical Implications

AIM

Rheumatoid arthritis is a prevalent worldwide disease, associated with an increased risk of multiple metabolic abnormalities that generate a higher disease burden.

OBJECTIVE

To gather the available evidence on the epidemiology, pathophysiology, current perspectives, clinical implications and prognosis of metabolic abnormalities in patients with rheumatoid arthritis.

METHODS

This is a narrative literature review. Search was conducted in PubMed, OVID, and Taylor & Francis databases, using the following MeSH terms: "Arthritis Rheumatoid", "Metabolic Diseases", and "Metabolic Syndrome".

RESULTS

This study describes the main metabolic manifestations of rheumatoid arthritis. Research has recognized that rheumatoid arthritis and metabolic abnormalities share pathophysiological mechanisms with an additive effect that increases cardiovascular risk. In that context, appropriate antirheumatic treatment can also impact on cardiovascular risk.

CONCLUSION

There are metabolic abnormalities in rheumatoid arthritis patients that increase cardiovascular risk. Therefore, it is crucial to evaluate cardiovascular risk to provide appropriate comprehensive management to reduce morbidity and mortality in patients with this disease.

Barriers and facilitators to physical activity in people with an inflammatory joint disease: a mixed methods study

Background

Physical activity has been shown to be of great benefit to people with an inflammatory joint disease (IJD), however people with an IJD have been shown to be very inactive compared to the general population. The aims of this study were to explore 1) whether the transition from a National Health Service (NHS)-run exercise programme into exercising in the community could be achieved successfully; and 2) the barriers and facilitators during the transition period.

Methods

This study adopted a complementary mixed-methods study design including a qualitative approach using focus groups and a prospective cohort study. Descriptive statistics were used to summarise the cohort study data. All variables were assessed for normality of distribution using the Sharpiro-Wilk test. Paired t-tests or Wilcoxon tests were undertaken for two consecutive assessment timepoints; one-way repeated measures ANOVAs or Friedman’s tests for three consecutive assessment timepoints. Micro-interlocutor analysis was used to analyse the focus group data. Areas of congruence and incongruence were explored by confirming the statistical results against the qualitative results. The adapted ecological model of the determinants of physical activity was then used as a framework to describe the findings.

Results

A successful transition was defined as still exercising in the community 6-months post discharge from the NHS-run Inflammatory Arthritis Exercise Programme. This was self-reported to be 90% of the cohort. An individual barrier to physical activity in people with an IJD was found to be the unpredictable nature of their condition. Other barriers and facilitators found were similar to those found in the general population such as recreation facilities, locations, transportation and cost. Other facilitators were similar to those found in people living with other chronic long-term conditions such as the importance of peer support.

Conclusions

90% of the cohort data were defined as a successful transition. People with an IJD have similar barriers and facilitators to exercise as the general population and those living with other chronic long-term conditions. A barrier which appears to be unique to this population group is that of the unpredictable nature of their condition which needs to be considered whenever tailoring any intervention.

Exercise intervention on cardiorespiratory fitness in rheumatoid arthritis patients with high cardiovascular disease risk: a single-arm pilot study

OBJECTIVE

In patients with rheumatoid arthritis (RA) with cardiovascular disease risk, it is unknown whether exercises are safe, improve cardiorespiratory fitness and reduce disease-related symptoms and cardiovascular-disease (CVD) risk factors. We aimed to investigate in RA patients with CVD risk: (1) safety of medium to high-intensity aerobic exercises, (2) potential changes of cardiorespiratory fitness and (3) disease activity and CVD risk factors in response to the exercises.

METHODS

Single-arm pilot-exercise intervention study including 26 consecutive patients (21 women) with > 4% 10-year risk of CVD mortality according to the Dutch Systematic Coronary Risk Evaluation. Aerobic exercises consisted of two supervised-sessions and five home-sessions per week for 12 weeks. Patients were required to exercise at intensities between 65 and 85% of their maximum heart rate. To assess safety, we recorded exercise related adverse events. Before and after the exercises, cardiorespiratory fitness was assessed with a graded maximal oxygen-uptake exercise test, while disease activity was evaluated via the Disease Activity Score-28 (DAS28) using the erythrocyte segmentation rate (ESR). Resting blood pressure, ESR and total cholesterol were assessed as CVD risk factors.

RESULTS

Twenty out of 26 patients performed the 12-week exercises without any adverse events. According to patients, withdrawals were unrelated to the exercises. Exercises increased cardiorespiratory fitness (pre: 15.91 vs. post: 18.15 ml.kg^-1 min^-1, p = 0.003) and decreased DAS28 (pre: 2.86 vs. post: 2.47, p = 0.04). No changes were detected in CVD risk factors.

CONCLUSION

A 12-week exercise intervention seems to be safe and improves cardiorespiratory fitness and disease activity in patients with RA with a high risk for cardiovascular diseases. Key Points 1. Rheumatoid arthritis patients with high cardiovascular disease risk were able to perform a maximum exercise test and a 12-week aerobic-based medium-to-high intensity exercise intervention. 2. The exercise intervention improved cardiorespiratory fitness and disease activity in rheumatoid arthritis patients with high cardiovascular disease risk. 3. Cardiorespiratory fitness levels were still low post-exercise intervention (i.e. 18.15 ml.kg-1min-1 compared to the 20.9 ml.kg-1min-1 baseline mean of the RA patients without CVD risk).

Integrated Analysis of miRNAs and Gene Expression Profiles Reveals Potential Biomarkers for Osteoarthritis

Purpose: Currently, the early diagnosis and treatment of osteoarthritis (OA) remain a challenge. In the present study, we attempted to explore potential biomarkers for the diagnosis and treatment of OA.

Methods: The differentially expressed genes (DEGs) were identified based on three mRNA datasets of synovial tissues for OA patients and normal controls downloaded from the Gene Expression Omnibus (GEO) database. Furthermore, Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were used for evaluating gene function related categories. Then, miRNA sequencing was performed for differentially expressed miRNAs’ identification. Finally, weighted gene co-expression network analysis (WGCNA) was performed for genes detected by the three mRNA datasets and a competing endogenous RNA (ceRNA) network with DEGs and differentially expressed microRNAs (miRNAs) was constructed for central genes identification. In addition, the relationship between central gene expression and immune infiltration was analyzed, and the candidate agents for OA were predicted based on the Connectivity Map database. Quantitative RT-PCR (qRT-PCR), Western blotting analysis, and immunofluorescent staining were performed to validate the expression levels of differentially expressed miRNAs and differentially expressed target genes in normal and OA tissues and chondrocytes. MiRNA–mRNA network was also validated in chondrocytes in vitro.

Results: A total of 259 DEGs and 26 differentially expressed miRNAs were identified, among which 94 miRNA–mRNA interactions were predicted. The brown module in WGCNA was most closely correlated with the clinical traits of OA. After overlapping the brown module genes with miRNA–mRNA pairs, 27 miRNA–mRNA pairs were obtained. A ceRNA network was constructed with 5505 lncRNA–miRNA–mRNA interactions. B-cell translocation gene 2(BTG2), Abelson-related gene (ABL2), and vascular endothelial growth factor A (VEGFA) were identified to be the central genes with good predictive performance, which were significantly correlated with immune cell infiltration in OA, reflected by declined activated dendritic cells (aDCs), and elevated contents of B cells, macrophages, neutrophils, and T helper cells. Anisomycin, MG-132, thapsigargin, and lycorine were predicted to be the potential candidate agents for OA intervention. In vitro, the expression levels of differentially expressed miRNAs and biomarkers identified in the present study were consistent with the results obtained in normal or OA knee cartilage tissues and chondrocytes. Furthermore, BTG2 was identified to be negatively regulated by miR-125a-5p.

Conclusion: BTG2, ABL2, and VEGFA can be regarded as potential predictive and treatment biomarkers for OA, which might guide the clinical therapy of OA.

MicroRNAs (miRNAs) in Cardiovascular Complications of Rheumatoid Arthritis (RA): What Is New?

Rheumatoid Arthritis (RA) is among the most prevalent and impactful rheumatologic chronic autoimmune diseases (AIDs) worldwide. Within a framework that recognizes both immunological activation and inflammatory pathways, the exact cause of RA remains unclear. It seems however, that RA is initiated by a combination between genetic susceptibility, and environmental triggers, which result in an auto-perpetuating process. The subsequently, systemic inflammation associated with RA is linked with a variety of extra-articular comorbidities, including cardiovascular disease (CVD), resulting in increased mortality and morbidity. Hitherto, vast evidence demonstrated the key role of non-coding RNAs such as microRNAs (miRNAs) in RA, and in RA-CVD related complications. In this descriptive review, we aim to highlight the specific role of miRNAs in autoimmune processes, explicitly on their regulatory roles in the pathogenesis of RA, and its CV consequences, their main role as novel biomarkers, and their possible role as therapeutic targets.

Time-averaged DAS28 and HAQ predict cardiovascular disease in patients with rheumatoid arthritis: data from KORONA registry

OBJECTIVE

To evaluate the predictive role of time-averaged disease activity score (DAS)28 and Health Assessment Questionnaire (HAQ) on cardiovascular disease (CVD) events in patients with rheumatoid arthritis (RA).

METHODS

Patients with RA were recruited from 23 tertiary hospitals. Baseline and annual follow-up data of demographic, laboratory, questionnaire, RA-associated parameters, and occurrence of CVD were collected. Patients were divided into three groups according to time-averaged DAS28: 1) remission (&lt;2.6), 2) low (2.6-3.2), 3) moderate (3.2-5.1), and 4) high (&gt;5.1). Kaplan-Meier curves was performed to compare the cumulative probability of CVD. Hazard ratios of each factor on the occurrence of CVD were obtained using Cox regression analyses.

RESULTS

A total of 4,034 RA patients with 826 for remission, 938 for low, 2,002 for moderate, and 268 for high time-averaged DAS28 groups were included. Baseline age, disease duration, ESR, CRP, DAS28, and HAQ scores were higher in the high time-averaged DAS28 group. The incidence rate of CVD was 2.86, 2.71, 3.53, and 8.13 events per 1,000 person-years for the remission, low, moderate, and high time-averaged DAS28 groups, respectively. The incidence rate ratio of CVD in the high time-averaged DAS28 group were 3.01 (95% CI 1.20-8.50) when compared to low time-averaged DAS28 group. The cumulative hazard for CVD in the high time-averaged DAS28 group was significantly high (log-rank P&lt;0.01). In multivariate Cox regression analysis, age, high time-averaged DAS28, and time-averaged HAQ&gt;0.5, were positively associated with CVD events in RA patients.

CONCLUSIONS

In patients with RA, time-averaged DAS28 and HAQ could predict the occurrence of CVD.

Effect of resistance exercise on serum leptin levels in a prospective longitudinal study of women patients with rheumatoid arthritis

Background

Exercise has an anti-inflammatory effect and reduces fat mass. Leptin has been known to be proinflammatory adipokines mainly produced by adipocytes. However, few studies have investigated the association between exercise and changes in serum leptin levels of patients with RA. This study evaluated the effect of an individualized resistance exercise on inflammatory markers including leptin as well as muscle strength and exercise capacity in patients with rheumatoid arthritis (RA).

Methods

A total of 42 age- and sex-matched participants were assigned to a resistance exercise program (60 min, once a week for 12 weeks, and self-exercise twice a week) or to a control group. Muscle strength, exercise capacities, and inflammatory markers such as cytokines and adipokines were assessed at baseline and at 12 weeks follow-up. Longitudinal changes in muscle strength, exercise capacity, cytokines, and adipokines between groups were tested with repeated measures analysis of variance or using the generalized estimating equation, with adjustment for baseline disease activity score 28-C response protein as a covariate.

Results

A total of 37 of 42 female patients with RA completed this prospective intervention study. Grip strength improved significantly in the exercise group (P < 0.05), while no between-group changes were found. Quadriceps contraction power (P for group-time interaction = 0.035 for the right side and P for group-time interaction = 0.012 for the left side) and 6-minute walking distance (P for group-time interaction = 0.021) were all improved significantly in the exercise group compared with the control group. In addition, serum leptin levels were significantly decreased in the exercise group compared with the control group (P for group-time interaction = 5.22 × 10⁻⁵), but not the other cytokines or adipokines. The change in serum leptin levels correlated with the changes in fat mass (Rho = 0.491, P= 0.015) and visceral fat area (Rho = 0.501, P= 0.013).

Conclusion

In addition to muscle strength and exercise capacity, the 12 weeks of individualized resistance exercise reduced serum leptin levels in keeping with body fat mass or visceral fat area, suggesting that serum leptin levels might be a surrogate marker of exercise in RA.

Environmental Enrichment Factors Associated with the Activity Level of Bottlenose Dolphins under Professional Care

Environmental enrichment can be used to improve the welfare of dolphins in zoos and aquariums. Bottlenose dolphins under professional care are typically provided with a range of enrichment that has a variety of features and levels of complexity at various frequencies. In the present study, a subset of data from a larger study entitled “Towards understanding the welfare of cetaceans in zoos and aquariums” (colloquially called the Cetacean Welfare Study) was used to examine the relationship between activity level and enrichment buoyancy as well as enrichment provisioning schedules. Survey data were collected from accredited zoos and aquariums related to the types of enrichment provided to the dolphins and the frequency and duration they were supplied. Non-invasive bio-logging devices were used to record the dolphin kinematics one day per week over the course of two five-week data collection periods. Activity level related positively with the total duration of time non-stationary enrichment was provided. In addition, providing a larger number of enrichment types each between 26% and 50% of the days in a month (i.e., rotating many different types of enrichment across days on a moderate schedule) was positively related to activity level. Activity level was negatively related to the number of times sinking enrichment was provided. Understanding how the temporal schedule and features of various types of enrichment are related to activity levels will aid in developing progressively more effective enrichment programs.

Monitoring and Managing Cardiovascular Risk in Immune Mediated Inflammatory Diseases

Cardiovascular disease (CVD) is common in immune-mediated inflammatory diseases (IMIDs) and it is predominately attributed to the interplay between chronic inflammation and traditional CVD risk factors. CVD has significant impact on the survival of patients with IMIDs as it is associated with increased morbidity and mortality. Despite recommendations for monitoring and managing CVD in patients with IMIDs, the individual CVD risk assessment remains problematic as CVD risk calculators for the general population consistently underestimate the risk in patients with IMIDs. Application of new technologies utilizing artificial intelligence techniques have shown promising potential for tailoring predictive medicine to the individual patient, but further validation of their role in clinical decision-making is warranted. In the meantime, individuals with IMIDs should be encouraged to adopt behavioral interventions targeting at modifiable lifestyle CVD risk factors, whereas rheumatologists need to be well aware of the unfavorable effects of antirheumatic medication on various CVD risk factors and outcomes. In the current paper, we aim to provide an overview of current and emerging strategies for mitigating CVD risk in patients with IMIDs, based on a practical approach.

Carotid Artery Pathology in Inflammatory Diseases

There is considerable evidence that patients with inflammatory conditions are at higher risk of developing cardiovascular (CV) disease including carotid artery stenosis. CV disease accounts for 35-50% of the excess mortality in patients with inflammatory diseases such as rheumatoid arthritis, with cerebrovascular disease being the second leading cause of death. We review current evidence regarding the association of inflammatory conditions and specifically carotid artery disease. Clinical epidemiological observations suggest that mechanisms other than classic risk factors may promote accelerated atherogenesis in rheumatoid and other inflammatory arthritis and carotid artery disease is increased in individuals with these conditions. Additional studies to better understand the underlying mechanisms and targeted strategies to mitigate such risk are indicated. For now, lifestyle modifications, aggressive treatment of risk factors and lipid lowering therapy in appropriate individuals is indicated.

Physical activity and sleep differences between osteoarthritis, rheumatoid arthritis and non-arthritic people in China: objective versus self report comparisons

BACKGROUND

Objectively measured differences in physical activity (PA) and sleep have been documented among people with osteoarthritis (OA) and rheumatoid arthritis (RA) compared to non-arthritic controls. However, it is not clear whether OA and RA subgroups also differ on these indexes or the extent to which distinct arthritis subgroups versus controls can be accurately identified on the basis of objective PA and sleep indexes compared to self-report responses on questionnaires. This study addressed these gaps.

METHODS

This case-control study comprised Chinese adults with OA (N = 40) or RA (N = 40) diagnoses based on physician assessments as well as a control group of adults without chronic pain (N = 40). All participants wore a Sensewear Armband (SWA) for consecutive 7 days and completed the International Physical Activity Questionnaire Short Form-Chinese as well as Pittsburgh Sleep Diary to obtain objective and subjective PA and sleep data, respectively.

RESULTS

There were no differences between the three groups on any self-report indexes of PA or sleep. Conversely, OA and RA subgroups displayed significantly lower PA levels and more sleep problems than controls did on a majority of SWA indexes, though arthritis subgroups were not differentiated from one another on these measures. Logistic regression analyses indicated four non-multicollinear SWA indexes (i.e., steps, active energy expenditure, vigorous activity, time awake after sleep onset) correctly identified the subgroup membership of 75.0-82.5% of participants with RA or OA while classification accuracy results were attenuated for controls.

CONCLUSIONS

Where possible, objective measures should be used to assess PA and sleep of adults with OA and RA while particular self-report PA questionnaires should be used sparingly.

Bottlenose dolphin habitat and management factors related to activity and distance traveled in zoos and aquariums

High-resolution non-invasive cetacean tagging systems can be used to investigate the influence of habitat characteristics and management factors on behavior by quantifying activity levels and distance traveled by bottlenose dolphins (Tursiops truncatus and Tursiops aduncus) in accredited zoos and aquariums. Movement Tags (MTags), a bio-logging device, were used to record a suite of kinematic and environmental information outside of formal training sessions as part of a larger study titled "Towards understanding the welfare of cetaceans in zoos and aquariums" (colloquially called the Cetacean Welfare Study). The purpose of the present study was to explore if and how habitat characteristics, environmental enrichment programs, and training programs were related to the distance traveled and energy expenditure of dolphins in accredited zoos and aquariums. Bottlenose dolphins in accredited zoos and aquariums wore MTags one day per week for two five-week data collection periods. Overall dynamic body acceleration (ODBA), a proxy for energy expenditure, and average distance traveled per hour (ADT) of 60 dolphins in 31 habitats were examined in relation to demographic, habitat, and management factors. Participating facilities were accredited by the Alliance for Marine Mammal Parks and/or Aquariums and the Association of Zoos & Aquariums. Two factors were found to be related to ADT while six factors were associated with ODBA. The results showed that enrichment programs were strongly related to both ODBA and ADT. Scheduling predictable training session times was also positively associated with ADT. The findings suggested that habitat characteristics had a relatively weak association with ODBA and were not related to ADT. In combination, the results suggested that management practices were more strongly related to activity levels than habitat characteristics.

Cardiorespiratory fitness and physical activity in people who have rheumatoid arthritis at an increased risk of cardiovascular disease: a cross-sectional study

Lower cardiorespiratory fitness (CRF) and physical activity (PA) associate with higher cardiovascular disease (CVD) risk, but the relationship between CRF and PA in people who have rheumatoid arthritis (RA) at an increased CVD risk (CVD-RA) is not known. The objectives of this study were to determine the levels of CRF and PA in people who have CVD-RA and to investigate the association of CRF with PA in people who have CVD-RA. A total of 24 consecutive patients (19 women) with CVD-RA (> 4% for 10-year risk of fatal CVD development as calculated using the Systematic Coronary Risk Evaluation)-were included in the study. CRF was assessed with a graded maximal exercise test determining maximal oxygen uptake (VO_2max). PA was assessed with an accelerometer to determine the amount of step count, sedentary, light and moderate-to-vigorous physical activity (MVPA) minutes per day. Mean age of patients was 65.3 ± 8.3 years. CRF mean values were 16.3 ± 1.2 ml·kg^-1 min^-1, mean step count per day was 6033 ± 2256, and the mean MVPA time was 16.7 min per day. Significant positive associations were found for CRF with step count (B = 0.001, P = 0.01) and MVPA time (B = 0.15, P = 0.02); a negative association was found for CRF with sedentary time (B =  - 0.02, P = 0.03). CRF is low and is associated with step count, sedentary time and MVPA time in people who have RA at an increased CVD risk.

Impact of the Uncoupling Protein 1 on Cardiovascular Risk in Patients with Rheumatoid Arthritis

Adiposity is strongly associated with cardiovascular (CV) morbidity. Uncoupling protein 1 (UCP1) increases energy expenditure in adipocytes and may counteract adiposity. Our objective was to investigate a connection between UCP1 expression and cardiovascular health in patients with rheumatoid arthritis (RA) in a longitudinal observational study. Transcription of UCP1 was measured by qPCR in the subcutaneous adipose tissue of 125 female RA patients and analyzed with respect to clinical parameters and the estimated CV risk. Development of new CV events and diabetes mellitus was followed for five years. Transcription of UCP1 was identified in 89 (71%) patients. UCP1 positive patients had often active RA disease (p = 0.017), high serum levels of IL6 (p = 0.0025) and were frequently overweight (p = 0.015). IL-6^hiBMI^hi patients and patients treated with IL6 receptor inhibitor tocilizumab had significantly higher levels of UCP1 compared to other RA patients (p < 0.0001, p = 0.032, respectively). Both UCP1^hi groups displayed unfavorable metabolic profiles with high plasma glucose levels and high triglyceride-to-HDL ratios, which indicated insulin resistance. Prospective follow-up revealed no significant difference in the incidence of new CV and metabolic events in the UCP1^hi groups and remaining RA patients. The study shows that high transcription of UCP1 in adipose tissue is related to IL6-driven processes and reflects primarily metabolic CV risk in female RA patients.

Effectiveness of resistance exercises in the treatment of rheumatoid arthritis: A meta-analysis

BACKGROUND

We aimed to assess the efficacy of resistance exercise in rheumatoid arthritis (RA) in randomized controlled trials (RCTs).

METHOD

PubMed, the Cochrane Library, and Embase were searched according to the index words to identify eligible RCTs, and relevant literature sources were also searched. The latest search was done in August 2019. Odds ratios (OR), mean difference (MD), and 95% confidence interval (95% CI) were used to analyze the main outcomes.

RESULT

Seventeen RCTs were included in the meta-analysis with 512 patients in the resistance exercise group and 498 patients in the control group. The results showed that compared with the control group, resistance exercise significantly decreased disease activity score in 28 joints (DAS-28) scores (standard mean difference [SMD]: -0.69, 95% CI: -1.26 to -0.11), reduced erythrocyte sedimentation rate (ESR) (SMD: -0.86, 95% CI: -1.65 to -0.07), and shortened the time of 50 ft. walking (SMD: -0.64, 95% CI: -0.99 to -0.28). No significant difference was observed in visual analog scale (VAS) scores (SMD: -0.61, 95% CI: -1.49-0.27) and health assessment questionnaire (HAQ) scores (weighted mean difference: -0.10, 95% CI: -0.26-0.06).

CONCLUSION

Resistance exercise showed reducing DAS-28 score, ESR score, and the time of 50 ft. walking in RA patients compared with the control group. However, high quality multicenter RCTs with larger sample sizes to confirm the conclusion.

[Safety aspects of the treatment with glucocorticoids for rheumatoid arthritis]

Glukokortikoide (GC) werden für die initiale Therapie der RA nach wie vor empfohlen – zeitlich befristet und in geringstmöglicher Dosierung. Ihre komplexe Wirkweise geht mit Nebenwirkungen einher, die v. a. in der Dauertherapie oberhalb von 5 mg Prednisolon pro Tag eine Rolle spielen. In diesem Dosisbereich begünstigen sie Osteoporose, Diabetes/Hyperglykämie, kardiovaskuläre Ereignisse und Infektionen und tragen damit zu einer vermehrten Frühsterblichkeit bei. Dabei sind die Risiken der GC-Therapie von patientenbezogenen Faktoren abhängig wie Alter, Komorbidität und Begleitmedikation. Ein negativer Einfluss sehr niedriger Steroiddosen auf das Gesamtüberleben ist möglicherweise bei hoher kumulativer Dosis nachweisbar, die Datenlage ist hier jedoch widersprüchlich. Das Monitoring einer GC-vermittelten Toxizität mithilfe eines validierten Index sollte in Zukunft dazu beitragen, die Vorteile einer steroidsparenden Behandlungsstrategie besser zu beschreiben. Selektiver wirkende Substanzen könnten in Zukunft eine Abkopplung der erwünschten Wirkungen von den Nebenwirkungen ermöglichen.

[Sports and exercise therapy in inflammatory rheumatic diseases]

Physical therapy has always been a pillar of the treatment of inflammatory rheumatic diseases in addition to targeted drug treatment; nevertheless, it is only established in the treatment guidelines for a few diseases. Within the last two decades the discovery of myokines has uncovered the physiological correlations of the anti-inflammatory effect of physical activity. For rheumatoid arthritis and spondylarthritis, several randomized controlled trials provide sufficient evidence to make well-founded recommendations. For connective tissue diseases (CTD) the data situation is clearly sparser but nevertheless shows that the positive effects of physical activity prevail. In the following article the authors present the most important clinical studies on sport and inflammatory rheumatic diseases and from these derive possible therapeutic recommendations.

Physical function in UK adults with osteogenesis imperfecta: a cross-sectional analysis of the RUDY study

We describe the physical function in adults with osteogenesis imperfecta (OI) and explored clinical and non-clinical factors related to its impairment. Our data showed that physical dysfunction is a common feature of adults with OI, varying by OI severity, and mediated by the presence and quality of pain and fatigue symptoms.

INTRODUCTION

There is a paucity of data describing physical function in adults with osteogenesis imperfecta (OI). We investigated the effects of OI and its severity on physical function and explored the relationship between physical function and number of fractures and symptomatology.

METHODS

Adults with OI of different types were recruited from the RUDY study, an ongoing UK-based prospective cohort study. Participants completed demographic and clinical questions and questionnaires. These assessed physical function (SF-36), mobility (EQ-5D-5L and NEADL), fatigue (FACIT-F), and pain (SF-MQ-2). Scores were compared using parametric or non-parametric statistical analyses, whereas correlations between outcomes were examined using univariate and multivariate regression analysis.

RESULTS

Seventy-eight adults with OI aged 43.5 ± 14.5 years were enrolled (type I, 32; type III, 11; type IV, 10; unknown type, 26). Physical function (PCS, SF-36) was significantly lower in all participants than normative values (p < 0.001) and in type III than type I (p = 0.008). Mobility was significantly different across the types (EQ-5D-EL, p = 0.007; NEADL, p < 0.001), with type III having more severe problems, followed by types IV, unknown, and I. Physical function was associated with OI type (r = 0.26; p = 0.021), presence and quality of pain (r = - 0.57; p < 0.0001), and fatigue (r = - 0.51; p < 0.0001). Multivariate analysis revealed that physical function correlated independently with age, OI type, fatigue, and non-neuropathic pain.

CONCLUSIONS

Individuals with OI display a marked deterioration in physical function during adulthood. This impairment varies in severity according to the OI phenotype and is associated with the presence of non-neuropathic pain and fatigue.

Factors Associated with Objectively Measured Physical Activity in Patients with Seropositive Rheumatoid Arthritis

Background: Rheumatoid arthritis (RA) is a chronic autoimmune disease, which is associated with low levels of physical activity (PA). However, the factors related to low physical activity levels have rarely been studied. Methods: In this cross-sectional study, 70 seropositive RA patients were included. Physical activity was objectively assessed with an ActiGraph GT3X+ accelerometer. In addition, body mass index, smoking status, work ability, and clinical parameters (functional disabilities, disease activity, disease duration, pain, and inflammation parameters) were measured. Results: RA patients performed a mean of 215.2 (SD: 136.6) min a week of moderate physical activity and 9.1 (SD: 26.3) min of vigorous physical activity. The total amount of moderate and vigorous physical activity (MVPA) was associated with BMI, and functional disabilities. In addition, non-smokers and patients with better work ability did more MVPA. No association could be seen with disease activity, disease duration, pain, and inflammatory markers. After mutual adjusting of all the variables, only BMI showed a significant relationship with MVPA. Conclusions: RA patients perform de facto no physical activity with vigorous intensity. Factors related to low physical activity are BMI, functional disabilities, workability and smoking status, whereas due to the study design no causal and temporal link could be made.

Mental Health and Psychological Wellbeing in Rheumatoid Arthritis during COVID-19 - Can Physical Activity Help?

In response to the COVID-19 pandemic, many countries have adopted community containment to manage COVID-19. These measures to reduce human contact, such as social distancing, are deemed necessary to contain the spread of the virus and protect those at increased risk of developing complications following infection with COVID-19. People with rheumatoid arthritis (RA) are advised to adhere to even more stringent restrictions compared to the general population, and avoid any social contact with people outside their household. This social isolation combined with the anxiety and stress associated with the pandemic, is likely to particularly have an impact on mental health and psychological wellbeing in people with RA. Increasing physical activity and reducing sedentary behaviour can improve mental health and psychological wellbeing in RA. However, COVID-19 restrictions make it more difficult for people with RA to be physically active and facilitate a more sedentary lifestyle. Therefore, guidance is necessary for people with RA to adopt a healthy lifestyle within the constraints of COVID-19 restrictions to support their mental health and psychological wellbeing during and after the COVID-19 pandemic.

Traditional and modern management strategies for rheumatoid arthritis

Rheumatoid arthritis (RA) is a serious disorder of the joints affecting 1 or 2% of the population aged between 20 and 50 years worldwide. RA is the foremost cause of disability in developing and Western populations. It is an autoimmune disease-causing inflammation and pain involving synovial joints. Pro-inflammatory markers, including cytokines, such as interleukin -1 (IL-1), IL-6, IL-7, IL-8, and tumor necrosis factor-α (TNF-α) are involved in RA. RA treatment involves TNF-α blockade, B cell therapy, IL-1 and IL-6 blockade, and angiogenesis inhibition. Synthetic drugs available for the treatment of RA include disease-modifying anti-rheumatic drugs (DMARD), such as cyclophosphamide, sulfasalazine, methotrexate, nonsteroidal anti-inflammatory drugs (NSAIDs), and intramuscular gold. These agents induce adverse hepatorenal effects, hypertension, and gastric ulcers. We found that patients diagnosed with chronic pain, as in RA, and those refractory to contemporary management are most likely to seek traditional medicine. Approximately 60-90% of patients with arthritis use traditional medicines. Therefore, the efficacy and safety of these traditional medicines need to be established. The treatment for RA entails a comprehensive multidisciplinary strategy to reduce pain and inflammation and to restore the activity of joints. The potential medicinal plants exhibiting anti-arthritic and anti-rheumatic pharmacological activity are reviewed here.

Misperception of the Cardiovascular Risk in Patients with Rheumatoid Arthritis

The risk of cardiovascular (CV) disease and mortality is increased by rheumatoid arthritis (RA). However, data on how RA patients perceive their own CV risk and their adherence to CV prevention factors are scarce. We conducted an observational study on 266 patients with RA to determine whether the perceived CV risk correlates to the objective CV risk, and if it influences their compliance with a Mediterranean diet and physical exercise. The objective CV risk was calculated according to the modified European League Against Rheumatism (EULAR) Systematic Coronary Risk Evaluation (SCORE). The perceived CV risk did not correlate to the objective CV risk. The correlation was even lower when carotid ultrasound was used. Notably, 64.62% of patients miscalculated their CV risk, with 43.08% underestimating it. Classic CV risk factors, carotid ultrasound markers and ESR and CRP showed significant correlation with the objective CV risk. However, only hypertension and RA disease features showed association with the perceived CV risk. Neither the objective CV risk nor the perceived CV risk were associated with the accomplishment of a Mediterranean diet or physical activity. In conclusion, RA patients tend to underestimate their actual CV risk, giving more importance to RA features than to classic CV risk factors. They are not concerned enough about the beneficial effects of physical activity or diet.

Exercise and inflammation

Based on current knowledge deriving from studies in animals and humans (the general population and patients with non-communicable diseases), there is biological plausibility that exercise may have anti-inflammatory effects. This may be particularly important for patients with chronic inflammatory rheumatic and musculoskeletal diseases (RMDs). The present review discusses the current state-of-the-art on exercise and inflammation, explores how exercise can moderate inflammation-dependent RMD outcomes and the most prevalent systemic manifestations and addresses the relationship between the dosage (particularly the intensity) of exercise and inflammation. We conclude that present data support potential beneficial effects of exercise on inflammation, however, the evidence specifically in RMDs is limited and inconclusive. More targeted research is required to elucidate the effects of exercise on inflammation in the context of RMDs.

Implementation of Physical Activity into routine Clinical pracTice in Rheumatic Musculoskeletal Disease: The IMPACT-RMD study protocol and rationale

Background:

Physical activity is an important intervention for improving disease-related symptoms and systemic manifestations in rheumatic and musculoskeletal disease (RMDs). However, studies suggest that RMD patients report that the lack of individualized and consistent information about physical activity from managing doctors and healthcare professionals, acts as a barrier for engagement. On the other hand, managing doctors and healthcare professionals report lack of knowledge in this area and thus lack of confidence to educate and advise RMD patients about the beneficial effects of physical activity. The aim of the present study therefore, is to develop two e-Learning courses for RMD doctors and health professionals: a) the first one to provide consistent information about the collective benefits of physical activity in RMDs and b) the second on how to implement physical activity advice in routine clinical practice.

Methods:

An international collaboration of seven countries, consisting of one academic institution and one patient organization from each country, will co-develop the two e-Learning courses. The final e-Learning courses will primarily target to improve – through physical activity advice – RMD symptoms which are important for patients.

Discussion:

The main result of this study will be to co-develop two e-Learning courses that can be used by managing RMD doctors and healthcare professionals to be made aware of the overall benefits of physical activity in RMDs as well as how to implement physical activity advise within their practice.

Effectiveness of an online self-management tool, OPERAS (an On-demand Program to EmpoweR Active Self-management), for people with rheumatoid arthritis: a research protocol

Background

Active self-management is a process where patients are fully engaged in managing their health in daily life by having access to contextualized health data and tailored guidance to support a healthy lifestyle. This study aims to determine whether an e-health intervention that incorporates symptom/disease activity monitoring and physical activity counselling can improve self-management ability in patients with rheumatoid arthritis (RA).

Methods

The ‘Empowering active self-management of arthritis: Raising the bar with OPERAS (an On-demand Program to EmpoweR Active Self-management)’ project is a randomized controlled trial that uses a delayed control design. One hundred thirty-four participants with RA will be randomly assigned to start the intervention either immediately (immediate group) or 6 months later (delayed group). The intervention involves (1) use of a Fitbit-compatible web app to record and monitor their RA disease activity, symptoms, and time spent on physical activity and a Fitbit; (2) group education and individual counselling by a physiotherapist (PT); and (3) six phone calls with a PT. The primary outcome measure is self-management ability measured by the Patient Activation Measure. Secondary outcome measures include disease status, fatigue, pain, depressive symptoms, and characteristics of habitual behavior and also time spent in physical activity and sedentary activity with a wearable multi-sensor device (SenseWear Mini). After the 6-month intervention, we will interview a sample of participants to examine their experiences with the intervention.

Discussion

The results of this study will help to determine whether this technology-enhanced self-management intervention improves self-management ability and health outcomes for people living with RA. A limitation of this study is that participants will need to self-report their symptoms, disease status, and treatment use through questionnaires on the OPERAS web app. The user-friendly interface, reminder emails from the research staff, and tailored guidance from PTs will encourage participants to actively engage with the app.

The effects of exercise on cardiovascular disease risk factors and cardiovascular physiology in rheumatoid arthritis

Cardiovascular disease (CVD) morbidity and mortality is highly prevalent in patients with rheumatoid arthritis (RA) with debilitating effects for the individual as well as significant healthcare impact. Current evidence demonstrates that engaging in aerobic and resistance exercise (i.e. structured physical activity) can significantly improve patient-reported and clinical index-assessed outcomes in RA. In addition to this, engagement in exercise programmes improves, in a dose-dependent manner, the risk of developing CVD as well as CVD symptoms and outcomes. The present narrative review uses evidence from systematic reviews and meta-analyses as well as controlled trials, to synthesize the current state-of-the-art on the potential effects of aerobic and resistance exercise on CVD risk factors as well as on cardiac and vascular function and structure in people with RA. Where there is a lack of evidence in RA to explain potential mechanisms, relevant studies from the general population are also discussed and linked to RA.

The Association Between Yoga Use, Physical Function, and Employment in Adults With Rheumatoid Arthritis

Mind-body exercises such as yoga offer patients with rheumatoid arthritis (RA) a symptom management strategy for improving physical and mental health. Studies have evaluated yoga to manage symptoms of RA and improve physical function; however, none has examined the relationship between yoga and work status in adults with RA. The objective was to describe differences in RA symptomatology, physical function scores, and work status between adults with RA who participate in yoga and those who do not. This cross-sectional study surveyed adults with rheumatologist-diagnosed RA regarding yoga use in the past year, symptoms, physical function, and work status. Differences between yoga and non-yoga participation groups were assessed with 2-sided t tests or Pearson χ tests. Multivariate linear regression analyses were conducted to identify significant associations between yoga participation and primary outcomes. The sample included 398 adults with RA; 88% were females, 66% were white, mean age 61.8 years, mean disease duration 24.8 years; 10.6% participated in yoga. Vinyasa, Bikram, Hatha, Iyengar, and restorative yoga styles were practiced, mostly in a group setting. Yoga participants were significantly more likely to work full-time, less likely to be unable to work due to disability, and had better physical function. These findings characterize yoga practice and practitioners among adults with RA. In adults with RA, yoga participation is associated with full-time work status and better physical function than nonparticipation. This study adds additional information to the growing body of literature about adults with RA who practice yoga.

[Physical activity, exercise and nutrition in rheumatism : Adjuvant treatment options for inflammatory-rheumatic diseases]

BACKGROUND AND OBJECTIVES

The positive effects of physical activity, physical training and an adaptation of diet on health have been scientifically proven for many diseases. Focusing on inflammatory rheumatic diseases and their potential comorbidities, positive effects are assumed from these two adjuvant treatment opportunities, which are examined in more detail in this review.

MATERIAL AND METHODS

Based on a literature search, randomized controlled trials (RCTs), non-RCT studies, reviews and recommendations from professional societies were included.

RESULTS

Physical activity and training show positive effects on the disease itself and also on its comorbidities with existing certainty. In addition, the exercise and training recommendations of the American College of Sports Medicine (ACSM) and the American Heart Association (AHA) provide recommendations, which were adapted by the European League Against Rheumatism (EULAR) to control intensity, duration and training extent. Nutritional medical approaches also provide preventive and rehabilitative beneficial possibilities.

DISCUSSION

The increase of physical activity, regular physical training and the adaptation of diet should be a basic additive component of the treatment of inflammatory rheumatic diseases. In individual sub-aspects, the study situation is very heterogeneous and requires further research.

Objective measurement of sedentary time and physical activity in people with rheumatoid arthritis: protocol for an accelerometer and activPALTM validation study

BACKGROUND

The accurate measurement of sedentary time and physical activity in Rheumatoid Arthritis (RA) is critical to identify important health consequences and determinants of these behaviours in this patient group. However, objective methods have not been well-validated for measurement of sedentary time and physical activity in RA.

AIMS

Specific objectives are to: 1) validate the ActiGraph GT3X+ accelerometer and activPAL3μTM against indirect calorimetry and direct observation respectively, and define RA-specific accelerometer cut-points, for measurement of sedentary time and physical activity in RA; 2) validate the RA-specific sedentary time accelerometer cut-points against the activPAL3μTM; 3) compare sedentary time and physical activity estimates in RA, using RA-specific vs. widely-used non-RA accelerometer cut-points.

METHODS

Objective 1: People with RA will wear an ActiGraph GT3X+, activPAL3μTM, heart rate monitor and indirect calorimeter, whilst being video-recorded undertaking 11 activities representative of sedentary behaviour, and light and moderate intensity physical activity. Objectives 2 and 3: People with RA will wear an ActiGraph GT3X+ and activPAL3μTM for 7 days to measure free-living sedentary time and physical activity.

DISCUSSION

This will be the first study to define RA-specific accelerometer cut-points, and represents the first validation of the ActiGraph accelerometer and activPALTM, for measurement of sedentary time and physical activity in RA. Findings will inform future RA studies employing these devices, ensuring more valid assessment of sedentary time and physical activity in this patient group.

Cardiorespiratory fitness in patients with rheumatoid arthritis is associated with the patient global assessment but not with objective measurements of disease activity

Objective

Patients with rheumatoid arthritis (RA) suffer from more cardiovascular disease (CVD), and develop cardiovascular risk factors at an earlier age than the general population. Cardiorespiratory fitness (CRF) is an important predictor of cardiovascular health. There are few data regarding CRF of RA patients, measured as peak oxygen uptake (VO_2peak) by the gold standard method; cardiopulmonary exercise testing. We compared CRF in RA patients to those from a healthy population, and investigated if risk factors for CVD and RA-specific variables including subjective and objective disease activity measures were associated with CRF in RA patients.

Methods

VO_2peak tests of RA patients (n=93) were compared to those of an age-matched and gender-matched healthy population (n=4631) from the Nord-Trøndelag Health Study. Predictors of VO_2peak were found using Lasso (least absolute shrinkage and selection operator) regression, followed by standardised multiple linear regression.

Results

Women with RA ≥40 years and men with RA aged 40-49 years or 60-69 years had up to 20% lower CRF than the healthy population in the same age groups. By relative importance, body mass index (standardised coefficient=-0.25, p<0.001), physical activity level (coefficient=0.21, p<0.001), patient global assessment (PGA; coefficient=-0.14, p=0.006), systolic blood pressure (coefficient=-0.12, p=0.016), resting heart rate (coefficient=-0.11, p=0.032) and smoking (coefficient=-0.10, p=0.046) were significant predictors of CRF (R²=0.82, gender-adjusted and age-adjusted).

Conclusion

CRF in RA patients was lower than in a healthy population. CRF was associated with common risk factors for CVD and the PGA score. Focusing on fitness in RA patients may improve cardiovascular health.

Factors associated with physical activity engagement among adults with rheumatoid arthritis: A cross-sectional study

OBJECTIVES

Physical activity (PA) has a number of benefits for rheumatoid arthritis (RA) patients. However, these patients are more physically inactive than the general population. The primary aim of this study was to investigate factors associated with PA engagement among RA patients. The secondary aim was to identify their preference for PA support.

METHODS

There were 96 participants, 76 of whom were female, with a mean age of 56.9 years (range = 34-72 years) and a median RA disease duration of 5 years (interquartile range = 2-12). All patients completed questionnaires assessing demographic status, health status (including cardiovascular disease [CVD] risk and RA disease profile), PA levels and preferences, alongside the perceived benefits of-and barriers to-PA. Hierarchical regressions were carried out to assess the relationship between reported PA levels and both engagement determinants and disease features.

RESULTS

Forty-five per cent (n = 44) had low levels (<600 metabolic equivalent-min/week) of PA. Low level of PA was significantly associated with: CVD risk profile (η_p ²  = 0.118, p < 0.002); functional disability (η_p ²  = 0.206, p < 0.032); pain (η_p ²  = 0.154, p < 0.028); general personal (η_p ²  = 0.190, p < 0.001) and arthritis-specific personal (η_p ²  = 0.170, p < 0.001) barriers to PA; age (η_p ²  = 0.076, p < 0.026); and sedentary behaviour (η_p ²  = 0.275, p < 0.001). Participants displayed a preference for unsupervised (n = 37, 38.5%), low-intensity (n = 45, 46.9%), indoor home (n = 50, 52.1%) exercises, with no preferences for the diversity of the exercise prescribed (n = 39, 40.6%) or for who provided the exercise counselling (n = 34, 35.4%).

CONCLUSIONS

These results suggest that CVD profile, disability, pain, and general and arthritis-specific personal barriers are associated with PA levels among RA patients. Intervention development should address these factors to facilitate an increase in PA uptake.

Comparison of the effects of exercise and anti-TNF treatment on cardiovascular health in rheumatoid arthritis: results from two controlled trials

People with rheumatoid arthritis (RA) are at increased risk for cardiovascular disease (CVD). Both pharmacological treatment and exercise are suggested in the management of CVD risk in RA. This study explored the effects of exercise and anti-TNF treatment on CVD risk in RA. Twenty RA patients (70% female, 50 (10) years) completed a 3-month exercise intervention and 23 RA patients (65% female, 54 (15) years) started anti-TNF treatment. Markers of disease activity, CVD risk, and vascular function were assessed before and after 3-months of intervention/treatment. Both exercise and anti-TNF treatment improved functional ability and fatigue, anti-TNF treatment was more successful in improving inflammation, disease activity, functional ability and pain. Exercise induced a reduction in overall CVD risk and improvement in vascular function, which was significantly different from anti-TNF treatment where no such changes were found. These findings showed that exercise and anti-TNF had differential effects on CVD risk in RA, and should be combined for optimal CVD risk reduction. Whereas anti-TNF treatment is likely to impact on CVD risk through reducing the systemic inflammatory load, exercise should be recommended to people with RA as an effective self-management strategy to reduce CVD risk further. Once RA patients have responded successfully to anti-TNF treatment, increasing exercise should be encouraged to reduce the risk for CVD. Thus, supporting exercise programmes when the disease is controlled, is likely to enhance the uptake and the maintenance of exercise, which will result in additional benefits to cardiovascular health and wellbeing in people with RA.
