Concurrent Intervention With Exercises and Stabilized Tumor Necrosis Factor Inhibitor Therapy Reduced the Disease Activity in Patients With Ankylosing Spondylitis: A Meta-Analysis

Effects of serum inflammatory factors, health index and disease activity scores on ankylosing spondylitis patients with sleep disorder

BACKGROUND

Patients with ankylosing spondylitis (AS) frequently suffer from comorbid sleep disorders, exacerbating the burden of the disease and affecting their quality of life.

AIM

To investigate the clinical significance of serum inflammatory factors, health index and disease activity scores in patients with AS complicated by sleep disorders.

METHODS

A total of 106 AS patients with comorbid sleep disorders were included in the study. The patients were grouped into the desirable and undesirable prognosis groups in accordance with their clinical outcomes. The serum levels of inflammatory factors, including C-reactive protein, erythrocyte sedimentation rate, interleukin (IL)-6, tumour necrosis factor-α and IL-1β, were measured. Disease activity scores, such as the Bath AS functional index, Bath AS disease activity index, Bath AS metrology index and AS disease activity score, were assessed. The health index was obtained through the Short Form-36 questionnaire.

RESULTS

The study found significant associations amongst serum inflammatory factors, health index and disease activity scores in AS patients with comorbid sleep disorders. Positive correlations were found between serum inflammatory factors and disease activity scores, indicating the influence of heightened systemic inflammation on disease severity and functional impairment. Conversely, negative correlations were found between disease activity scores and health index parameters, highlighting the effect of disease activity on various aspects of health-related quality of life. Logistic regression analysis further confirmed the predictive value of these factors on patient outcomes, underscoring their potential utility in risk assessment and prognostication.

CONCLUSION

The findings demonstrate the intricate interplay amongst disease activity, systemic inflammation and patient-reported health outcomes in AS patients complicated by sleep disorders. The results emphasise the need for comprehensive care strategies that address the diverse needs and challenges faced by these patients and underscore the potential relevance of serum inflammatory factors, health index and disease activity scores as prognostic markers in this patient population.

Effects of physical exercise and body weight on disease-specific outcomes of people with rheumatic and musculoskeletal diseases (RMDs): systematic reviews and meta-analyses informing the 2021 EULAR recommendations for lifestyle improvements in people with RMDs

BACKGROUND

A European League Against Rheumatism (EULAR) taskforce was convened to develop recommendations for lifestyle behaviours in rheumatic and musculoskeletal diseases (RMDs). This paper reviews the literature on the effects of physical exercise and body weight on disease-specific outcomes of people with RMDs.

METHODS

Three systematic reviews were conducted to summarise evidence related to exercise and weight in seven RMDs: osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, axial spondyloarthritis (axSpA), psoriatic arthritis, systemic sclerosis and gout. Systematic reviews and original studies were included if they assessed exercise or weight in one of the above RMDs, and reported results regarding disease-specific outcomes (eg, pain, function, joint damage). Systematic reviews were only included if published between 2013-2018. Search strategies were implemented in the Medline, Embase, Cochrane Library of systematic reviews and CENTRAL databases.

RESULTS

236 articles on exercise and 181 articles on weight were included. Exercise interventions resulted in improvements in outcomes such as pain and function across all the RMDs, although the size of the effect varied by RMD and intervention. Disease activity was not influenced by exercise, other than in axSpA. Increased body weight was associated with worse outcomes for the majority of RMDs and outcomes assessed. In general, study quality was moderate for the literature on exercise and body weight in RMDs, although there was large heterogeneity between studies.

CONCLUSION

The current literature supports recommending exercise and the maintenance of a healthy body weight for people with RMDs.

Treat-to-target in axial spondyloarthritis - what about physical function and activity?

In patients with axial spondyloarthritis (axSpA), pain, functional and structural impairments, reduced mobility and potential deformity of the axial skeleton are the most prominent health concerns. Limitations in physical function and spinal mobility are caused by both inflammation and structural damage, and therefore restrictions to physical function must be monitored throughout a patient's life. Consequently, the assessment of physical function is recommended as a key domain in the Assessment of Spondyloarthritis International Society-OMERACT Core Outcome Set. However, in comparison with disease activity, physical function seems to be a relatively neglected target of intervention in patients with axSpA, even though physical function is a major contributor to costs and disability in this disease. This Review aims to reacquaint rheumatologists with the targets for physical function, physical activity and performance by giving guidance on determinants of physical function and how physical function can be examined in patients with axSpA.

Therapeutic exercises and rehabilitation in axial spondyloarthropathy: Balancing benefits with unique challenges in the Asia-Pacific countries

The burden of axial spondyloarthropathy (axSpA) in the Asia-Pacific region is substantial. The management of axSpA has been revolutionized with the advent of biological therapy where the disease activity, functional disability and negative psychological affect can be mitigated to a great extent. On the other hand, exercise remains an essential component of the treatment of axSpA at all stages, which is often discounted or underused. This is compounded by a gap in demand and supply between increasing number patients with axSpA and paucity of trained specialists and rehabilitation personnel in the Asia-Pacific countries. The acceptability and uptake of therapeutic exercise is strikingly poor in this region because of multiple factors such as lack of awareness among health professionals and the general population, poor healthcare infrastructure, lack of resources and limited accessibility to rehabilitation services. Health authorities and professional bodies in these countries need to work in tandem to expand healthcare facilities, encourage training opportunities and promote safe and effective exercise interventions which is accessible to the general population and individuals with axSpA. Adequate patient education, optimum control of disease activity and strict adherence to therapeutic exercise is essential to predict the best clinical outcome. In this narrative review we have appraised the impact of therapeutic exercise in this era of biological therapies in axSpA and have explored the challenges of rehabilitation services in the Asia-Pacific countries. Overall, the available quality of evidence is mixed, acknowledging the beneficial role of exercise and optimum usage and protocols pertaining to axSpA specific exercises and therefore further research is warranted.

The comparative efficacy of supervised- versus home-based exercise programs in patients with ankylosing spondylitis: A meta-analysis

OBJECTIVES

The aim of this meta-analysis is to investigate the comparative efficacy between supervised- and home-based programs in patients with ankylosing spondylitis (AS).

METHOD

A systematic search in PubMed, Web of Science, EMBASE, and the Cochrane Library was electronically performed by 2 independent investigators in order to capture all potential studies comparing supervised- with home-based in patients with AS from inception to April 2018. After extracted essential information, apprised risk of bias, statistical analysis was performed with Review Manager (RevMan) software (version 5.3.0). The protocol was registered at PROSPERO platform with an identifier of CRD42018097046.

RESULTS

A total of 7 studies comprising 271 patients were included finally. Meta-analyses showed that, compared to home-based program, supervised-based program was associated with reduced bath ankylosing spondylitis metrology index (BASMI) scores (mean difference [MD], -0.45; 95% confidence interval [CI], -0.73, -0.17), bath ankylosing spondylitis disease activity index (BASDAI) scores (MD, -0.48; 95% CI, -0.88, -0.08), and bath ankylosing spondylitis functional index (BASFI) scores (MD, -0.78; 95% CI, -1.19, -0.37). However, depression scores (standard mean difference, -0.22; 95% CI, -0.58, 0.14) between the 2 groups showed no significant defference.

CONCLUSIONS

Both supervised- and home-based programs can benefit to reduce BASMI, BASDAI, and BASFI scores in AS patients. However, short-term, supervised exercise program may be more effective than home-based exercises at decreasing disease activity with AS.

Exercise programmes for ankylosing spondylitis

BACKGROUND

Exercise programmes are often recommended for managing ankylosing spondylitis (AS), to reduce pain and improve or maintain functional capacity.

OBJECTIVES

To assess the benefits and harms of exercise programmes for people with AS.

SEARCH METHODS

We searched CENTRAL, the Cochrane Library, MEDLINE Ovid, EMBASE Ovid, CINAHL EBSCO, PEDro, Scopus, and two trials registers to December 2018. We searched reference lists of identified systematic reviews and included studies, handsearched recent relevant conference proceedings, and contacted experts in the field.

SELECTION CRITERIA

We included reports of randomised controlled trials (RCT) of adults with AS that compared exercise therapy programmes with an inactive control (no intervention, waiting list) or usual care.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodology.

MAIN RESULTS

We included 14 RCTs with 1579 participants with AS. Most participants were male (70%), the median age was 45 years (range 39 to 47), and the mean symptom duration was nine years. The most frequently used exercises were those designed to help improve strength, flexibility, stretching, and breathing. Most exercise programmes were delivered along with drug therapy or a biological agent. We judged most of the studies at unclear or high risk of bias for several domains. All 14 studies provided data obtained immediately upon completion of the exercise programme. The median exercise programme duration was 12 weeks (interquartile range (IQR) 8 to 16). Three studies (146 participants) provided data for medium-term follow-up (< 24 weeks after completion of the exercise programmes), and one (63 participants) for long-term follow-up (> 24 weeks after completion of the exercise programmes). Nine studies compared exercise programmes to no intervention; five studies compared them to usual care (including physiotherapy, medication, or self-management).Exercise programmes versus no interventionAll data were obtained immediately upon completion of the exercise programme.For physical function, measured by a self-reporting questionnaire (the Bath Ankylosing Spondylitis Functional Index (BASFI) scale, 0 to 10; lower is better), moderate-quality evidence showed a no important clinically meaningful improvement with exercise programmes (mean difference (MD) -1.3, 95% confidence interval (CI) -1.7 to -0.9; 7 studies, 312 participants; absolute reduction 13%, 95% CI 17% to 9%).For pain, measured on a visual analogue scale (VAS, 0 to 10, lower is better), low-quality evidence showed an important clinically meaningful reduction of pain with exercise (MD -2.1, 95% CI -3.6 to -0.6; 6 studies, 288 participants; absolute reduction 21%, 95% CI 36% to 6%).For patient global assessment of disease activity, measured by a self-reporting questionnaire (the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scale, 0 to 10, lower is better), moderate-quality evidence showed no important clinically meaningful reduction with exercise (MD -0.9, 95% CI -1.3 to -0.5; 6 studies, 262 participants; absolute reduction 9%, 95% CI 13% to 5%).For spinal mobility, measured by a self-reporting questionnaire (the Bath Ankylosing Spondylitis Metrology Index (BASMI) scale, 0 to 10, lower is better), very low-quality evidence showed an improvement with exercise (MD -0.7 95%, -1.3 to -0.1; 5 studies, 232 participants) with no important clinical meaningful benefit (absolute reduction 7%, 95% CI 13% to 1%).For fatigue, measured on a VAS (0 to 10, lower is better), very low-quality evidence showed a no important clinically meaningful reduction with exercise (MD -1.4, 95% CI -2.7 to -0.1; 2 studies, 72 participants; absolute reduction 14%, 95% CI 27% to 1%).Exercise programmes versus usual careAll data were obtained immediately upon completion of the exercise programme.For physical function, measured by the BASFI scale, moderate-quality evidence showed an improvement with exercise (MD -0.4, 95% CI -0.6 to -0.2; 5 studies, 1068 participants). There was no important clinical meaningful benefit (absolute reduction 4%, 95% CI 6% to 2%).For pain, measured on a VAS (0 to 10, lower is better), moderate-quality evidence showed a reduction of pain with exercise (MD -0.5, 95% CI -0.9 to -0.1; 2 studies, 911 participants; absolute reduction 5%, 95% CI 9% to 1%). No important clinical meaningful benefit was found.For patient global assessment of disease activity, measured by the BASDAI scale, low-quality evidence showed a reduction with exercise (MD -0.7, 95% CI -1.3 to -0.1; 5 studies, 1068 participants), but it was not clinically important (absolute reduction 7%, 95% CI 13% to 1%) with important clinical meaningful benefitFor spinal mobility, measured by the BASMI scale, very low-quality evidence found a no important clinically meaningful improvement with exercise (MD -1.2, 95% CI -2.8 to 0.5; 2 studies, 85 participants; absolute reduction 12%, 95% CI 5% less to 28% more). There was no important clinical meaningful benefit.None of the studies measured fatigue.Adverse effectsWe found very low-quality evidence of the effect of exercise versus either no intervention, or usual care. We are uncertain of the potential for harm of exercises, due to low event rates, and a limited number of studies reporting events.

AUTHORS' CONCLUSIONS

We found moderate- to low-quality evidence that exercise programmes probably slightly improve function, may reduce pain, and probably slightly reduce global patient assessment of disease activity, when compared with no intervention, and measured upon completion of the programme. We found moderate- to low-quality evidence that exercise programmes probably have little or no effect on improving function or reducing pain, when compared with usual care, and may have little or no effect on reducing patient assessment of disease activity, when measured upon completion of the programmes. We are uncertain whether exercise programmes improve spinal mobility, reduce fatigue, or induce adverse effects.

Associated factors with adherence to standard exercise therapy and health-related quality of life in Chinese patients with ankylosing spondylitis

Objectives: The aim of this study is to assess the current situations of standard exercise treatment and predictors of non-standard exercise in Chinese patients with ankylosing spondylitis (AS). An analysis of the effect of standard exercise on health-related quality of life (HR-QoL) was also conducted.Methods: In the cross-sectional study, a total of 259 AS patients were constantly invited to participate in this study and complete the questionnaire under the researchers' supervision in a clinical setting including sociodemographic variables, clinical variables, psychological variables, and HR-QoL. Data were analyzed by Mann-Whitney U test, Chi-square test as well as multivariable analysis of Binary Stepwise Logistic Regression.Results: The data showed that just 20.5% of them could complete the standard exercise. Exercise adherence was associated with employment, educational level, marital status, place of residence, treatment of Tumor Necrosis Factor-α inhibitor, knowledge about exercise, disease duration, clinical variables, and anxiety. The HR-QoL in the group of standard exercise was better than that in the non-standard exercise group. Logistic Regression Analysis showed that lower educational level, less knowledge about benefits of exercise treatment and higher score of Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were the independent risk factors of exercise treatment non-adherence.Conclusion: AS patients educated less than 9 years or with higher BASDAI score were more likely not to adhere to standard exercise treatment. Non-adherence to exercise treatment among AS patients is exceedingly common, particularly in patients without knowledge about benefits of exercise treatment. Standard exercise treatment can also improve HR-QoL of AS patients.

Sclerostin rather than Dickkopf-1 is associated with mSASSS but not with disease activity score in patients with ankylosing spondylitis

OBJECTIVE

To determine the serum levels of Dickkopf-1 (DKK-1) and sclerostin, as well as their correlations with the structural damage assessed by modified stoke ankylosing spondylitis spine score (mSASSS) and the disease activity evaluated by ankylosing spondylitis disease activity score (ASDAS) in patients with ankylosing spondylitis (AS).

METHODS

Eighty-eight AS patients, 26 rheumatoid arthritis (RA) patients, and 26 age- and gender-matched healthy controls (HC) were collected from rheumatic clinic of the Second Affiliated Hospital of Zhejiang University, School of Medicine, between March 2015 and July 2015. Demographic data, parameters of ASDAS, and image evaluations of spine (i.e., mSASSS) were collected. The serum levels of DKK-1 and sclerostin were measured using commercially available ELISA kits.

RESULTS

Both DKK-1 and sclerostin were significantly higher in the AS patients than in the controls (1855 ± 84.58 vs. 1406 ± 99.76 pg/ml and 106 ± 6.75 vs. 62.78 ± 6.39 pmol/l, respectively, P < 0.05). The correlation analysis suggested a negative correlation between serum sclerostin and mSASSS (P = 0.019, r² = 0.062). DKK-1 had a trend of positive correlation with mSASSS, but was not statistically significant (P > 0.05). There was no association between the serum levels of DKK-1 or sclerostin and disease activity assessed by ASDAS (P > 0.05). DKK-1 and sclerostin had a negative correlation (P = 0.013, r² = 0.07).

CONCLUSION

In the present study, the expressions of serum DKK-1 and sclerostin were independent of disease activity. Sclerostin was negatively correlated with the mSASSS, which suggests that sclerostin may be a potential marker indicating the spine ossification process in AS. The specific mechanism remains to be investigated.

Exercise for Athletes With Inflammatory Arthritis

Advances in pharmacologic management of inflammatory conditions have allowed those living with these conditions to pursue fitness activities previously difficult due to functional limitations. With that said, many patients with inflammatory arthritis are still not active enough. In this article, we review specific exercise recommendations for a number of inflammatory conditions with a focus on overall health promotion and cardiovascular disease risk reduction, discuss exercise as an adjunct to pharmacologic disease management, and review potential risks of sport participation for athletes with inflammatory arthritis conditions.

The comparative efficacy of group- versus home-based exercise programs in patients with ankylosing spondylitis: Protocol for a meta-analysis

BACKGROUND

Ankylosing spondylitis (AS) is an important factor to not only cause employment obstacle, but also result in serious social economic load. Several randomized controlled trials investigated the efficacy of group- versus home-based exercise programs in patients with AS. This systematic review will collect and summarize the available evidence to realize the effectiveness of group- and home-based programs in patients with AS.

METHODS

A search in PubMed, Web of Science, EMBASE, and the Cochrane Library will be electronically performed by 2 independent investigators to capture all potential studies comparing group- and home-based in patients with AS. The time limit of search will be from their inception to April 2018. Two independent investigators provide their agreement in presencial meeting for a final selection, and at a later stage, the articles will be reviewed in full-text by the all authors. Quantitative analysis will be performed with Review Manager (RevMan) software (version 5.3.0).

RESULTS

This meta-analysis will provide a high-quality synthesis of current evidence of group- versus home-based exercise programs in patients with AS.

CONCLUSION

The conclusion of our meta-analysis will provide the evidence which program is an effective intervention for patient with AS.

Clinical improvement and reduction in serum calprotectin levels after an intensive exercise programme for patients with ankylosing spondylitis and non-radiographic axial spondyloarthritis

Background

The efficacy of exercise therapy for ankylosing spondylitis (AS) is well-documented, but dearth of information is for non-radiographic axial spondyloarthritis (nr-axSpA).

Biomarkers like serum calprotectin, interleukins IL-6, IL-17 and tumour necrosis factor (TNF)-α may reflect the disease activity of axial spondyloarthritis (axSpA). In this study, we investigated clinical and laboratory parameters of both axSpA subgroups in response to intensive physical exercise.

Methods

Altogether, 46 patients with axSpA, characterised according to the Assessment of SpondyloArthritis International Society criteria as having nr-axSpA or AS underwent 6-month exercise programme. Clinical outcomes of disease activity, Bath AS Disease Activity Index (BASDAI), AS Disease Activity Index (ASDAS-CRP), mobility, Bath AS Metrology Index (BASMI) and function, Bath AS Functional Index (BASFI) were evaluated at baseline and at the end of the exercise programme. Serum IL-6 and IL-17, TNF-α and calprotectin were measured via ELISA. The clinical and laboratory data of 29 control axSpA patients were used for the evaluation of the results.

Results

In all axSpA patients, the ASDAS-CRP (2.10 ± 0.12 to 1.84 ± 0.11, p <0.01) and BASMI (1.28 ± 0.14 to 0.66 ± 0.84, p <0.0001) improved after 6 months of exercise therapy. There was a significant improvement in the ASDAS-CRP in the nr-axSpA subgroup (2.01 ± 0.19 to 1.73 ± 0.16, p <0.05) and in the BASMI in both, the nr-axSpA and the AS subgroups (1.09 ± 0.12 to 0.47 ± 0.08, p <0.0001 and 1.43 ± 0.24 to 0.82 ± 0.23, p <0.0001, respectively). Both, ASDAS-CRP and BASDAI, were significantly improved in the exercise axSpA group compared to the control axSpA group (mean -0.26 vs. -0.13 and -0.49 vs. 0.12, respectively, all p <0.05). Only calprotectin was significantly reduced after the exercise programme in nr-axSpA and AS patients (from 2379.0 ± 243.20 to 1779.0 ± 138.30 μg/mL and from 2430.0 ± 269.70 to 1816.0 ± 148.20 μg/mL, respectively, all p <0.01). The change in calprotectin was more profound in the axSpA intervention group (mean -604.56) than in the control axSpA (mean -149.28, p <0.05).

Conclusion

This study demonstrated similar efficacy for an intensive exercise programme in both nr-axSpA and AS patients. A significant decrease in serum calprotectin levels in both subgroups of axSpA patients after the exercise programme reflected an improvement in the disease activity and spinal mobility.
