Physical activity prevents bone loss in premenopausal women with rheumatoid arthritis: a cohort study

Gait rehabilitation for foot and ankle impairments in early rheumatoid arthritis: a feasibility study of a new gait rehabilitation programme (GREAT Strides)

Background

Foot impairments in early rheumatoid arthritis are common and lead to progressive deterioration of lower limb function. A gait rehabilitation programme underpinned by psychological techniques to improve adherence, may preserve gait and lower limb function. This study evaluated the feasibility of a novel gait rehabilitation intervention (GREAT Strides) and a future trial.

Methods

This was a mixed methods feasibility study with embedded qualitative components. People with early (< 2 years) rheumatoid arthritis (RA) and foot pain were eligible. Intervention acceptability was evaluated using a questionnaire. Adherence was evaluated using the Exercise Adherence Rating Scale (EARS). Safety was monitored using case report forms. Participants and therapists were interviewed to explore intervention acceptability. Deductive thematic analysis was applied using the Theoretical Framework of Acceptability. For fidelity, audio recordings of interventions sessions were assessed using the Motivational Interviewing Treatment Integrity (MITI) scale. Measurement properties of four candidate primary outcomes, rates of recruitment, attrition, and data completeness were evaluated.

Results

Thirty-five participants (68.6% female) with median age (inter-quartile range [IQR]) 60.1 [49.4–68.4] years and disease duration 9.1 [4.0–16.2] months), were recruited and 23 (65.7%) completed 12-week follow-up. Intervention acceptability was excellent; 21/23 were confident that it could help and would recommend it; 22/23 indicated it made sense to them. Adherence was good, with a median [IQR] EARS score of 17/24 [12.5–22.5]. One serious adverse event that was unrelated to the study was reported. Twelve participants’ and 9 therapists’ interviews confirmed intervention acceptability, identified perceptions of benefit, but also highlighted some barriers to completion. Mean MITI scores for relational (4.38) and technical (4.19) aspects of motivational interviewing demonstrated good fidelity. The Foot Function Index disability subscale performed best in terms of theoretical consistency and was deemed most practical.

Conclusion

GREAT Strides was viewed as acceptable by patients and therapists, and we observed high intervention fidelity, good patient adherence, and no safety concerns. A future trial to test the additional benefit of GREAT Strides to usual care will benefit from amended eligibility criteria, refinement of the intervention and strategies to ensure higher follow-up rates. The Foot Function Index disability subscale was identified as the primary outcome for the future trial.

Role of Secreted Frizzled-Related Protein 1 and Tumor Necrosis Factor-α (TNF-α) in Bone Loss of Patients with Rheumatoid Arthritis

Bone loss is one of the emerging extra-articular manifestations of rheumatoid arthritis. TNF-α is the main inflammatory cytokine that can directly increase bone resorption. However, its role in bone formation is still unknown, especially related to secreted frizzled-related protein 1 (SFRP-1), an osteoblast inhibitor. This study examines the correlation between TNF-α and SFRP-1, with a bone turn over marker (CTX and P1NP). This is a cross-sectional study with 38 subjects of premenopausal female patients with RA. This study found that 60.6% of the patients were in remission or low disease activity. The median of TNF-α was 10.6 pg/mL, mean of SFRP-1 was 9.29 ng/mL, mean of CTX was 2.74 ng/mL, and the median of P1NP was 34.04 pg/ml. There is positive correlation between TNF-α and P1NP (r = 0.363, p = 0.026), also between SFRP-1 and P1NP (r = 0.341; p = 0.036). A low level of TNF-𝛼, high level of SFRP-1, high level of CTX, and low level of P1NP in this study indicate a high bone turn over process, with dominant resorption activity in premenopausal female patients with RA.

Physical activity and sedentary behavior in women with rheumatoid arthritis: a comparison of patients with low and high disease activity and healthy controls

Objective: In rheumatoid arthritis (RA) patients, low levels of physical activity (PA) and high levels of sedentary behavior (SB) may play a role in enhancing cardiovascular risk. We do not know how long-term control of disease activity impacts upon daily PA levels and if treated patients attain PA levels seen in healthy controls. We therefore compared habitual levels of PA and SB between female RA patients with low disease activity achieved by anti-tumor necrosis factor (TNF) therapy, those with active arthritis (aRA) and non-RA controls.

Methods: We carried out a cross-sectional comparison of 40 RA patients on anti-TNF therapy for >2 years with DAS28<3.2 (tRA), 32 patients on conventional disease modifying anti-rheumatic drugs with DAS28>3.2 (aRA) and 34 healthy controls (C) with the groups matched for age and body mass index. PA was assessed using the ActiGraph accelerometer to determine step count and time spent in moderate-to-vigorous physical activity (MVPA), light activity and sedentary time.

Results: Daily step count was 72% higher in tRA and 40% higher in C in comparison to aRA (p<0.01). Sedentary time (as a proportion of wear time) was 10% less in tRA than aRA (p=0.03), while light activity time was 18% higher (p=0.014). Both RA groups had 40% lower MVPA time than C (p=0.001). Only half of either RA group fulfilled current WHO guidelines for PA compared with 82% of controls.

Conclusion: RA patients who had long-term disease suppression were more physically active with less SB compared to RA patients with active disease. They had similar light PA and SB to controls although lower MVPA. Behavioral change interventions are likely to be needed in order to restore moderate exercise, further reduce SB and to meet guidelines for daily PA.

Exercise participation has increased in patients with Rheumatoid Arthritis: A cross-sectional comparison between two Dutch RA cohorts

Objective:

This study evaluates exercise participation in patients with rheumatoid arthritis (RA) and the percentage of patients that meet the recommended level of physical activity (at least 150 minutes per week moderate-intensity physical activity) in two cross-sectional questionnaires in 2013 and 2016 in two Dutch RA cohorts.

Methods:

In 2013, a cross-sectional study was performed among 740 patients with RA from seven outpatient clinics from the Dutch DREAM registry. Subsequently in 2016, 498 patients with RA of the outpatient clinic of the Bernhoven Hospital (member of the DREAM registry) participated in a similar study. In both years, patients filled in an identical questionnaire about exercise participation (frequency and duration). In 2016, items about self-efficacy to become more physically active were added to the questionnaire.

Results:

In 2016, patients with RA spent significantly more minutes per week in exercise activities compared to 2013: 180 (150–450) and 120 (60–225) minutes per week, respectively (P<0.001). The percentage of patients with RA who met the recommended physical activity level increased from 25% in 2013 to 57% in 2016. Almost half (44%) of the non-exercisers reported feeling confident to become more physically active.

Conclusion:

Compared to 2013, RA patients participated in 2016 more frequently and spent more minutes per week in exercise activities. This resulted in a higher percentage of patients who met the recommended physical activity level. A personalized physical activity program, with a focus on identifying barriers and setting personal goals, might further increase the physical activity level of patients with RA.

Physical inactivity and sedentary behavior: Overlooked risk factors in autoimmune rheumatic diseases?

This review aims to (1) summarize the estimates of physical inactivity and sedentary behavior in autoimmune rheumatic diseases; (2) describe the relationship between physical (in)activity levels and disease-related outcomes; (3) contextualize the estimates and impact of physical inactivity and sedentary behavior in autoimmune diseases compared to other rheumatic diseases and chronic conditions; and (4) discuss scientific perspectives around this theme and potential clinical interventions to attenuate these preventable risk factors. We compiled evidence to show that estimates of physical inactivity and sedentary behavior in autoimmune rheumatic diseases are generally comparable to other rheumatic diseases as well as to other chronic conditions (e.g., type 2 diabetes, cardiovascular diseases, and obesity), in which a lack of physical activity and excess of sedentary behavior are well-known predictors of morbimortality. In addition, we also showed evidence that both physical inactivity and sedentary behavior may be associated with poor health-related outcomes (e.g., worse disease symptoms and low functionality) in autoimmune rheumatic diseases. Thus, putting into practice interventions to make the patients "sit less and move more", particularly light-intensity activities and/or breaking-up sedentary time, is a simple and prudent therapeutic approach to minimize physical inactivity and sedentary behavior, which are overlooked yet modifiable risk factors in the field of autoimmune rheumatic diseases.

Physical activity in patients with rheumatoid arthritis

INTRODUCTION

Rheumatoid arthritis (RA) is the most common chronic inflammatory joint disease and is associated with an excess risk of cardiovascular disease. For the general population, the World Health Organization has issued detailed recommendations on the type of physical activity appropriate for decreasing the cardiovascular risk. The objective of this work is to review available data on the effects of physical activity in patients with RA.

RESULTS

RA is responsible for a marked decrease in physical activity. Physical activity significantly diminishes both the cardiovascular risk and the DAS 28. Vascular benefits from physical activity include improved endothelial function and slowing of the atherosclerotic process. Physical activity also has favorable effects on bone, slowing radiographic disease progression in small joints and increasing bone mineral density at the femoral neck, although these effects are not statistically significant. Finally, engaging in physical activity increases self-esteem, alleviates symptoms of depression, improves sleep quality, and decreases pain perception. Aerobic exercise is the most commonly advocated type of physical activity. Most interventions were of short duration (4 weeks) and involved aerobic activity (running or cycling) for 60minutes a day 5 days a week. Resistance training has been shown to decrease systemic inflammation and increase muscle strength. The main obstacles to physical activity in patients with RA are related to both the patients, who lack both motivation and knowledge, and the rheumatologists, who also lack knowledge and place insufficient emphasis on promoting physical activity.

CONCLUSION

Physical activity provides many benefits in patients with RA and should be widely performed. Promoting physical activity should be among the objectives of therapeutic patient education for RA.

A review of osteoporosis management in younger premenopausal women

The purpose of this review is to describe the available evidence for osteoporosis treatments in young and premenopausal women. A review of articles evaluating the treatment or prevention of osteoporosis in young (age less than 50 years) or premenopausal women was conducted. Several trials evaluating the treatment of anorexia nervosa and use of hormone therapy in those women, the use of bisphosphonates in women undergoing chemotherapy for breast cancer and the use of bisphosphonates, teriparatide and vitamin D in women with glucocorticoid-induced osteoporosis are described. Limited data were found to support the treatment of osteoporosis in women with idiopathic osteoporosis or cystic fibrosis, or after kidney transplant. The evidence for treatment of osteoporosis in premenopausal women is not nearly as robust as that for postmenopausal osteoporosis. Although fracture risk in the premenopausal population is low, women with secondary osteoporosis may benefit from treatment with various agents, depending upon the condition.

EULAR evidence-based and consensus-based recommendations on the management of medium to high-dose glucocorticoid therapy in rheumatic diseases

To develop recommendations for the management of medium to high-dose (ie, >7.5 mg but ≤100 mg prednisone equivalent daily) systemic glucocorticoid (GC) therapy in rheumatic diseases. A multidisciplinary EULAR task force was formed, including rheumatic patients. After discussing the results of a general initial search on risks of GC therapy, each participant contributed 10 propositions on key clinical topics concerning the safe use of medium to high-dose GCs. The final recommendations were selected via a Delphi consensus approach. A systematic literature search of PubMed, EMBASE and Cochrane Library was used to identify evidence concerning each of the propositions. The strength of recommendation was given according to research evidence, clinical expertise and patient preference. The 10 propositions regarded patient education and informing general practitioners, preventive measures for osteoporosis, optimal GC starting dosages, risk-benefit ratio of GC treatment, GC sparing therapy, screening for comorbidity, and monitoring for adverse effects. In general, evidence supporting the recommendations proved to be surprisingly weak. One of the recommendations was rejected, because of conflicting literature data. Nine final recommendations for the management of medium to high-dose systemic GC therapy in rheumatic diseases were selected and evaluated with their strengths of recommendations. Robust evidence was often lacking; a research agenda was created.

Are persons with rheumatoid arthritis deconditioned? A review of physical activity and aerobic capacity

BACKGROUND

Although the general assumption is that patients with rheumatoid arthritis (RA) have decreased levels of physical activity, no review has addressed whether this assumption is correct.

METHODS

Our objective was to systematically review the literature for physical activity levels and aerobic capacity (VO2max). in patients with (RA), compared to healthy controls and a reference population. Studies investigating physical activity, energy expenditure or aerobic capacity in patients with RA were included. Twelve studies met our inclusion criteria.

RESULTS

In one study that used doubly labeled water, the gold standard measure, physical activity energy expenditure of patients with RA was significantly decreased. Five studies examined aerobic capacity. Contradictory evidence was found that patients with RA have lower VO2max than controls, but when compared to normative values, patients scored below the 10th percentile. In general, it appears that patients with RA spend more time in light and moderate activities and less in vigorous activities than controls.

CONCLUSION

Patients with RA appear to have significantly decreased energy expenditure, very low aerobic capacity compared to normative values and spend less time in vigorous activities than controls.

Health education improves both arthritis-related illness and self-rated health: an intervention study among older people in rural Bangladesh

OBJECTIVES

To examine changes in self-reported arthritis-related illness and self-rated health as a result of a health education intervention, and the association between self-reported arthritis-related illness and self-rated health.

STUDY DESIGN

A quasi-experimental study was conducted in eight randomly selected villages in rural Bangladesh (intervention = 4; control = 4).

METHODS

The intervention consisted of home-based physical activities, health advice and aspects of healthcare management over 15 months followed by a 3-month latent period. Data were collected before the intervention and after the latent period. Analyses included 839 participants (≥60 years of age) who participated in both surveys. Participants in the intervention area were further categorized into two groups who self-reported compliance or non-compliance with recommended health advice. Self-rated health was assessed using a single global question. Self-reported arthritis-related illness was indicated by the presence of arthritis, back and joint pain, biting sensation, swelling and inflammation in the joints.

RESULTS

Hierarchical logistic regression analyses revealed that positive effects on episodes of arthritis-related illness [odds ratio (OR) 1.9, 95% confidence interval (CI) 1.3-2.8] and self-rated health (OR 1.4, 95% CI 1.0-1.9) were more likely among the compliant group compared with the control group. Furthermore, positive self-rated health was more likely among participants reporting a positive change in their arthritis-related illness (OR 2.2, 95% CI 1.5-3.2). The results also showed that literate and non-poor participants were more likely to report positive health, and participants with advancing age were less likely to report positive health.

CONCLUSION

Community-based health education is effective in reducing the burden of arthritis-related illness and in enhancing general health in old age.

Association of physical function and physical activity in women with rheumatoid arthritis

OBJECTIVE

To explore the associations between measures of physical activity (PA) and measures of physical function (PF) in women with rheumatoid arthritis (RA). We hypothesized that the strength of the associations between PA and PF would be moderate, and that after controlling for social and biomedical characteristics, the associations would decrease.

METHODS

Women with RA (n = 47, mean +/- SD age 56.5 +/- 7.0 years) participated in the cross-sectional analysis of this study. Social and biomedical characteristics explored included age, ethnicity, disease duration, marital and educational status, height, weight, comorbidity, and disease activity. PF was measured by the self-reported Health Assessment Questionnaire (HAQ) and by a battery of performance-based measures that included self-selected gait speed, the 5 chair rise test, and the single leg stance test. PA was measured by a portable activity monitor worn for 10 days, and was characterized in 2 ways: daily average number of steps and daily energy expenditure during moderate levels of PA.

RESULTS

Correlations between measures of PA and PF were small to moderate (zero-order correlations = 0.189-0.479). After controlling for social and biomedical characteristics, the correlations became smaller (semi-partial correlations = 0.095-0.277) and only HAQ score remained significantly associated with PA.

CONCLUSION

Associations between measures of PA and measures of PF were explained, in part, by social and biomedical characteristics in women with RA. The results indicate that measures of PF and PA may represent different constructs and support the need to measure PA in rehabilitation research in RA.

Hand bone mineral density is associated with both total hip and lumbar spine bone mineral density in post-menopausal women with RA

OBJECTIVE

RA is associated with localized bone loss in the hands, as well as generalized osteoporosis. We evaluated the relationship between hand digital X-ray radiogrammetry BMD (DXR-BMD) and total hip and lumbar spine BMD.

METHODS

We conducted a cross-sectional study of 138 post-menopausal women with RA. The DXR-BMD was calculated based on digitized hand radiographs. Measurements of the total hip and lumbar spine BMD were performed by a DXA-BMD (BMDa) scan. Patient and physician questionnaires and laboratory samples supplied information on relevant covariates. Separate multivariate linear regression models were constructed to determine the cross-sectional relationship between hand DXR-BMD (independent variable) and total hip or lumbar spine BMD (dependent variables).

RESULTS

The cohort comprised women with a median age of 61 years and RA disease duration of 13 years. Seventy-six per cent were either RF and/or anti-cyclic citrullinated peptide (anti-CCP) positive and most had moderate disease activity [median disease activity score-28 joint count (DAS28) 3.7]. Hand DXR-BMD was significantly associated with total hip BMD (beta = 0.61; P < 0.0001) and lumbar spine BMD (beta = 0.62; P < 0.0008) in adjusted models.

CONCLUSIONS

This study suggests that hand DXR-BMD is associated with both the total hip and lumbar spine BMD among post-menopausal women with RA. The relationship between bone loss in the hands and generalized osteoporosis should be further explored in longitudinal studies of patients with RA.
