Meta-Analysis
BACKGROUND
To prove that serum vitamin D (VD) levels are strongly associated with ankylosing spondylitis (AS) disease activity, the association between serum VD levels and key monitoring indicators of AS disease activity has been analyzed, such as the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP).
METHODS
Studies published in PubMed, Cochrane Library, EMBASE, and China National Knowledge Infrastructure by August 30, 2022 were searched, and 6 studies finally met the selection criteria. Serum 25-hydroxyvitamin D (25(OH)D), ESR, CRP levels, and correlation coefficients between serum VD and BASDAI, ESR, CRP in AS, and control in these studies were extracted for the meta-analysis.
RESULTS
When compared to controls, patients with AS had considerably lower blood 25(OH)D levels (MD = -7.53 ng/mL, 95% CI, -9.78 to -5.28, P < .001) and significantly higher ESR and CRP levels (ESR: MD = 11.75 mm/h, 95% CI, 4.20 to 19.31, P = .002; CRP: MD = 15.36 mg/L, 95% CI, 4.95 to 25.77, P = .004). Additionally, a negative correlation was discovered between serum VD levels and BASDAI, ESR, and CRP (Fisher' Z = -0.34, -0.38, -0.35, respectively).
CONCLUSION
The findings of our meta-analysis demonstrated a negative correlation between serum VD levels and the main monitoring indices of disease activity in patients with AS and verified that the differences in the continent and ethnicity may be one of the major contributors to this finding.

Review
OBJECTIVES
Ankylosing spondylitis (AS) is a chronic rheumatic disease which affects the axial skeleton and sacroiliac joints. By impacting spinal mobility and physical functions, AS could also potentially impair gait. However, while published data are rather sparse, it appears that discrepancies exist regarding AS consequences on gait characteristics, tasks and analysis techniques used to assess gait ability of patients with AS. The review questions are twofold: (1) How is gait assessed in patients with AS? and (2) What are the consequences of AS on gait?
METHODS
Databases were systematically searched to identify studies satisfying the search criteria, using the synonyms of ankylosing spondylitis and gait. Two reviewers extracted from the articles study characteristics, methods and main results in relation to gait.
RESULTS
192 titles were extracted from databases and 21 studies were included in the review. 16 studies (76%) used clinical gait measurements and 5 (23%) used laboratory gait measurements. Only 7 involved a healthy control group. Studies used various protocols, instructions and parameters when assessing gait. Gait of patients with AS was associated with decreased stride length, pelvic movements and lower limbs angles in the sagittal plane, and increased hip abduction and external rotation compared to healthy controls.
CONCLUSIONS
Only few studies have assessed gait characteristics in patients with AS and published data evidence that kinematic parameters of gait is altered, but no consensus exists regarding gait analysis methods for patients with AS. Guidelines are provided to improve the design and methodology for future studies on gait and AS.

Review
BACKGROUND
Achievement of remission is a desirable outcome and the identification of predictors of remission may aid in the clinical management of axial spondyloarthritis (axSpA). Our aim was to summarise predictors of remission in people with axSpA.
METHODS
In this systematic literature review (SLR), we searched MEDLINE, EMBASE, and Cochrane CENTRAL from their inception to May 20, 2022, and 2020-2021 American College of Rheumatology (ACR) and European Alliance of Associations for Rheumatology (EULAR) meeting abstracts. We included randomized controlled trials and cohort studies in which prognostic factors associated with remission were investigated by multivariable analysis.
RESULTS
The SLR comprised 21 articles from 4592 citations. Three studies investigated "sustained remission" (≥3 consecutive visits), while the other assessed "point remission" (at single points in time, varying from 12 weeks to 8 years). The most used remission criteria were Ankylosing Spondylitis Disease Activity Score (ASDAS) inactive disease (14 studies) and Assessment of SpondyloArthritis international Society partial remission criteria (11 studies). Younger age, HLA-B27 positivity, male gender, lower baseline Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), lower baseline Bath Ankylosing Spondylitis Functional Index (BASFI), lower baseline ASDAS-C-reactive protein, treatment with tumour necrosis factor inhibitors (TNFi), and concomitant use of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs), were the most consistent predictors of remission. Additionally, shorter disease duration, lower Health Assessment Questionnaire for the spondyloarthropathies and TNFi naivety were predictors of remission in two studies. Other factors were found to be predictors of remission in one study only.
CONCLUSIONS
Predictors of remission in axSpA were identified. However, many of these predictors were only identified in 1-2 studies. Considering the differences in study design, further well-designed prognostic studies are needed to confirm and allow generalisation of these predictors to the general axSpA population.

Meta-Analysis Review
BACKGROUND
One- and two-level osteotomies have been used to treat thoracolumbar kyphosis in patients with ankylosing spondylitis (AS). However, the effectiveness and safety of the 2 methods have not been systematically compared, and few studies have reported on which method might be more suitable for treating AS.
METHODS
We performed a systematic literature search. All comparative studies of one- and two-level osteotomy for the treatment of thoracolumbar kyphosis caused by AS were included. Efficacy was determined by the radiographic outcomes, including global kyphosis, sagittal vertical axis, and lumbar lordosis and the Oswestry disability index. The complication rates were used to assess the safety. We analyzed the data using Review Manager software.
RESULTS
A total of 10 studies were included and used for the meta-analysis. We pooled the studies according to the type of data they had reported to evaluate the radiographic correction and incidence of complications. We found that two-level osteotomy provided advantages compared with one-level osteotomy for spinal correction, including global kyphosis and lumbar lordosis. However, the correction was dependent on the degree of preoperative kyphosis. In addition, we found no differences between the 2 groups in the correction of the sagittal vertical axis or improvement in the Oswestry disability index. However, we did find differences in the incidence of neural complications, dural tear, and operative site infection.
CONCLUSIONS
Our findings have shown that one-level osteotomy is safer than two-level osteotomy. For AS patients with nonsevere kyphosis, one-level osteotomy will be sufficient for spinal sequence correction and maintenance of balance, and two-level osteotomy will not be needed. For AS patients with severe kyphosis, two-level osteotomy can be recommended for better orthopedic effects; however, a careful surgical technique is required.

Safety of Upadacitinib in Immune-Mediated Inflammatory Diseases: Systematic Literature Review of Indirect and Direct Treatment Comparisons of Randomized Controlled Trials.
INTRODUCTION
Immune-mediated inflammatory diseases including rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), non-radiographic axial spondylarthritis (nr-axSpA), atopic dermatitis (AD), ulcerative colitis (UC), and Crohn's disease (CD) pose a substantial burden on patients and their quality of life. Upadacitinib is an orally administered, selective, and reversible Janus kinase inhibitor indicated for seven conditions, but data on its safety versus other active treatments are limited. A systematic literature review of indirect and direct treatment comparisons of randomized controlled trials (RCTs) was conducted to assess the safety profile of upadacitinib.
METHODS
MEDLINE, Embase, and Cochrane Library databases were searched for indirect and direct treatment comparisons of RCTs that (1) included licensed upadacitinib dosages; (2) studied any of the seven conditions; (3) reported any adverse events (AEs), serious AEs (SAEs), AEs leading to discontinuation, major adverse cardiovascular event, venous thromboembolism, malignancies, infections or serious infections, and death; and (4) were published between January 2018 and August 2022.
RESULTS
A total of 25 studies were eligible for inclusion. SAEs, AEs leading to discontinuation, and any AEs were commonly studied. RA was the most studied condition, followed by AD and UC. Most studies (16/25, 64%) reported no statistically significant difference in the studied safety outcomes between upadacitinib and other active treatments (e.g., tumor necrosis factor blockers, interleukin receptor antagonists, integrin receptor antagonists, T cell co-stimulation modulator), or placebo (placebo ± methotrexate or topical corticosteroids). Other studies (9/25, 36%) reported mixed results of no statistically significant difference and either statistically higher (8/25, 32%) or lower rates (1/25, 4%) on upadacitinib.
CONCLUSION
Most studies suggested that upadacitinib has no statistically significant difference in the studied safety outcomes compared to active treatments or placebo in patients with RA, PsA, AS, AD, UC, and CD. A few studies reported higher rates, but findings were inconsistent with limited interpretation.

RMD Open Nov 2020Review of efficacy and safety of Janus kinase (JAK) inhibition in immune-mediated inflammatory diseases (IMIDs).
OBJECTIVES
Review of efficacy and safety of Janus kinase (JAK) inhibition in immune-mediated inflammatory diseases (IMIDs).
METHODS
A systematic literature research (SLR) of all publications on JAK inhibitors (JAKi) treatment published until March 2019 using MEDLINE, EMBASE and the Cochrane Library. Efficacy and safety were assessed in randomised controlled trials (RCTs), integrating long-term extension periods additionally for safety evaluation.
RESULTS
3454 abstracts were screened with 85 included in the final analysis (efficacy and RCT safety: n=72; safety only: n=13). Efficacy of RCTs investigating tofacitinib (TOFA, n=27), baricitinib (BARI, n=9), upadacitinib (UPA, n=14), filgotinib (FILGO, n=7), decernotinib (DEC, n=3) and peficitinib (PEF, n=7) was evaluated. Six head-to-head trials comparing JAKi with tumour necrosis factor inhibitors (TNFi) were included. Efficacy of JAKi was shown in rheumatoid arthritis (RA) for all agents, psoriatic arthritis (TOFA, FILGO), ankylosing spondylitis (TOFA, FILGO), systemic lupus erythematosus (BARI), chronic plaque psoriasis (TOFA, BARI, PEF), ulcerative colitis (TOFA, UPA), Crohn's disease (UPA, FILGO) and atopic dermatitis (TOFA, BARI, UPA). Safety analysis of 72 RCTs, one cohort study and 12 articles on long-term extension studies showed increased risks for infections, especially herpes zoster, serious infections and numerically higher rates of venous thromboembolic events. No increased malignancy rates or major adverse cardiac events were observed.
CONCLUSION
JAKi provide good efficacy compared to placebo (and to TNFi in RA and Pso) across various IMIDs with an acceptable safety profile. This SLR informed the task force on points to consider for the treatment of IMIDs with JAKi with the available evidence.

BACKGROUND
The current core outcome set for ankylosing spondylitis (AS) has had only minor adaptations since its development 20 years ago. Considering the significant advances in this field during the preceding decades, an update of this core set is necessary.
OBJECTIVE
To update the ASAS-OMERACT core outcome set for AS into the ASAS-OMERACT core outcome set for axial spondyloarthritis (axSpA).
METHODS
Following OMERACT and COMET guidelines, an international working group representing key stakeholders (patients, rheumatologists, health professionals, pharmaceutical industry and drug regulatory agency representatives) defined the core domain set for axSpA. The development process consisted of: i) Identifying candidate domains using a systematic literature review and qualitative studies; ii) Selection of the most relevant domains for different stakeholders through a 3-round Delphi survey involving axSpA patients and axSpA experts; iii) Consensus and voting by ASAS; iv) Endorsement by OMERACT. Two scenarios are considered based on the type of therapy investigated in the trial: symptom modifying therapies and disease modifying therapies.
RESULTS
The updated core outcome set for axSpA includes 7 mandatory domains for all trials (disease activity, pain, morning stiffness, fatigue, physical function, overall functioning and health, and adverse events including death). There are 3 additional domains (extra-musculoskeletal manifestations, peripheral manifestations and structural damage) that are mandatory for disease modifying therapies and important but optional for symptom modifying therapies. Finally, 3 other domains (spinal mobility, sleep, and work and employment) are defined as important but optional domains for all trials.
CONCLUSION
The ASAS-OMERACT core domain set for AS has been updated into the ASAS-OMERACT core domain set for axSpA. The next step is the selection of instruments for each domain.

Meta-Analysis Review
BACKGROUND
The last decade has witnessed the increasing use of biologics for the treatment of ankylosing spondylitis (AS). Drug survival is an outcome incorporating real-world effectiveness and safety. However, the drug survival of biologics in treating AS is unclear.
OBJECTIVE
The aim was to assess the drug survival of biologics (tumor necrosis factor inhibitors and anti-interleukin-17 monoclonal antibodies) in treating AS.
METHODS
We conducted a systematic review and meta-analysis and searched the PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), and Embase databases up to 13th May 2020. Studies that analyzed the drug survival of biologics for AS and reported the respective annual data for each biologic for at least 1 year were included. Two authors independently screened and selected studies and assessed their risk of bias. A third author was available for arbitrating discrepancies. The Newcastle-Ottawa Scale was employed to evaluate the risk of bias of included studies. We conducted a random-effects model meta-analysis to obtain pooled drug survival from year 1 to 5. We performed subgroup analyses for biologic-naïve patients, first-line versus second- and third-line biologics, discontinuation due to loss of effectiveness and adverse effects, and high-quality studies.
RESULTS
We included 39 studies with 32,493 patients. The drug survival decreased from 76% at year 1 to 51% at year 5 for etanercept, from 75 to 51% for adalimumab, from 76 to 53% for infliximab, from 72 to 49% for golimumab, and from 63 to 57% for certolizumab pegol. The drug survival rate for secukinumab was 0.77 (95% confidence interval 0.64‒0.90) at year 1. Subgroup analyses on biologic-naïve patients and discontinuation due to adverse effects found no differences in the drug survival of various biologics except for a lower drug survival of infliximab in biologic-naïve patients. The drug survival for first-line biologics was higher than for second- and third-line biologics.
CONCLUSION
To the best of our knowledge, this study is the first systematic review and meta-analysis on the drug survival of biological therapies for AS patients. The drug survival of all biologics in treating AS appeared comparable, but is higher in first-line biologics than second- and third-line biologics. To date there are scarce data on the drug survival of newly available biologics, for example, anti-interleukin-17 biologics.

Review
BACKGROUND
Axial spondyloarthritis (axSpA) is an inflammatory rheumatic disease associated with chronic back pain and restricted mobility and physical function. Increasing physical activity is a viable strategy for improving the health and quality of life of patients with axSpA. Thus, quantifying physical activity and sedentary behavior in this population is relevant to clinical outcomes and disease management. However, to the best of our knowledge, no systematic review to date has identified and synthesized the available evidence on the use of wearable devices to objectively measure the physical activity or sedentary behavior of patients with axSpA.
OBJECTIVE
This study aimed to review the literature on the use of wearable activity trackers as outcome measures for physical activity and sedentary behavior in patients with axSpA.
METHODS
PubMed, PEDro, and Cochrane electronic databases were searched in July 2021 for relevant original articles, with no limits on publication dates. Studies were included if they were original articles, targeted adults with a diagnosis of axSpA, and reported wearable device-measured physical activity or sedentary behavior among patients with axSpA. Data regarding the study's characteristics, the sample description, the methods used for measuring physical activity and sedentary behavior (eg, wearable devices, assessment methods, and outcomes), and the main results of the physical activity and sedentary behavior assessments were extracted.
RESULTS
A total of 31 studies were initially identified; 13 (13/31, 42%) met the inclusion criteria, including 819 patients with axSpA. All the studies used accelerometer-based wearable devices to assess physical activity. Of the 13 studies, 4 (4/31, 31%) studies also reported outcomes related to sedentary behavior. Wearable devices were secured on the wrists (3/13 studies, 23%), lower back (3/13, 23%), right hip (3/13, 23%), waist (2/13, 15%), anterior thigh (1/13, 8%), or right arm (1/13, 8%). The methods for reporting physical activity and sedentary behavior were heterogeneous. Approximately 77% (10/13) of studies had a monitoring period of 1 week, including weekend days.
CONCLUSIONS
To date, few studies have used wearable devices to quantify the physical activity and sedentary behavior of patients with axSpA. The methodologies and results were heterogeneous, and none of these studies assessed the psychometric properties of these wearables in this specific population. Further investigation in this direction is needed before using wearable device-measured physical activity and sedentary behavior as outcome measures in intervention studies in patients with axSpA.

Meta-Analysis
Comparison of pedicle subtraction osteotomy and vertebral column decancellation for the correction of thoracolumbar kyphotic deformity in ankylosing spondylitis: a systematic review and meta-analysis.
OBJECTIVE
The goal in this study was to compare the efficacy and safety outcomes of vertebral column decancellation (VCD) and pedicle subtraction osteotomy (PSO) for patients with ankylosing spondylitis (AS) with thoracolumbar kyphotic deformity.
METHODS
This study was registered on the International Prospective Register of Systematic Reviews (PROSPERO). The authors conducted a computer search of PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wan Fang Database, and Wei Pu Database to collect controlled clinical studies on the efficacy and safety of VCD and PSO for patients with AS with thoracolumbar kyphotic deformity. The search covered the period from database establishment to March 2023. Two researchers screened the literature, extracted data, and evaluated the risk of bias of the included studies; these researchers recorded the authors and the sample size, and they extracted data on the intraoperative blood loss, Oswestry Disability Index, spine sagittal parameters, operation time, and complications in each study. Meta-analysis was performed using RevMan 5.4 software provided by Cochrane Library.
RESULTS
A total of 6 cohort studies with a total of 342 patients were included in this study, including 172 patients in the VCD group and 170 patients in the PSO group. The VCD group had lower intraoperative blood loss than the PSO group (mean difference [MD] -274.92, 95% CI -506.63 to -43.20, p = 0.02); significant correction of the sagittal vertical axis compared with the PSO group (MD 7.32, 95% CI -1.24 to 15.87, p = 0.03), and the operation time was shorter than that of the PSO group (MD -80.28, 95% CI -150.07 to -10.48, p = 0.02).
CONCLUSIONS
This systematic review and meta-analysis showed that VCD had more advantages than PSO in correcting the sagittal imbalance in the treatment of AS with thoracolumbar kyphotic deformity, and VCD had less intraoperative blood loss, shorter operation time, and satisfactory results in improving the quality of life.
