Effects of disease-modifying anti-rheumatic drugs on sacroiliac MRI score in axial spondyloarthritis: a systematic review and meta-analysis. Clin Rheumatol 2024; 43:1045-1052. [PMID: 38158505 DOI: 10.1007/s10067-023-06849-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 12/12/2023] [Accepted: 12/16/2023] [Indexed: 01/03/2024]
Abstract
INTRODUCTION Sacroiliac bone marrow edema is an important factor in the diagnosis and management of axial spondyloarthritis (axSpA). The aim of this meta-analysis is to assess the effect of the different bDMARDs and tsDMARDs on the SPARCC score at 12-16 and 48-52 weeks. METHODS A systematic review, performed on PubMed (including Medline), Cochrane (CENTRAL) and DOAJ databases, included randomized controlled studies evaluating the sacroiliac joint (SIJ) SPARCC score at 12-16 or 48-52 weeks in patients with axSpA meeting the ASAS 2009 criteria or the modified New York criteria. We included studies evaluating the effects of the different treatments on the SPARCC score of SIJ in axial spondyloarthritis in comparison to a control group. RESULTS Eighteen studies were included in the meta-analysis. Nine studies evaluated the effect of TNFα inhibitors (TNFi), three for IL-17 inhibitors, and four for JAK inhibitors. At 12 and 16 weeks, SIJ SPARCC score was significantly improved by TNFi (WMD: - 3.29 [95% CI - 4.25; - 2, 34]), by IL-17 inhibitors (WMD: - 4.66 [95% CI - 6.22; - 3.09]), and by JAK inhibitors (JAKi) (WMD: - 3.06 [95% CI - 3.24; - 2.89]). There was no difference between the molecule subgroups. At 48-52 weeks, TNFα inhibitors reduced more SIJ SPARCC, but not significantly (WMD: - 2.26 [95% CI - 4.94; 0.42]), than placebo groups who began a TNFi treatment with delay. CONCLUSION Our meta-analysis shows a comparable improvement of the SIJ SPARCC score regarding TNFi, JAKi, and IL-17 inhibitors at three months and suggests the presence of an opportunity window. Key Points • Anti-TNF Ab, anti-IL17 Ab, and JAK inhibitor treatments reduce the sacroiliac joint SPARCC scores. • There is no difference between the different treatments in the reduction of the sacroiliac joint SPARCC score after 3 months in axial spondyloarthritis.

Abstract
We aimed to develop evidence-based recommendations for treating axial spondylarthritis (axSpA) in Korea. The development committee was constructed, key clinical questions were determined, and the evidence was searched through online databases including MEDLINE, Embase, Cochrane, KoreaMed, and Kmbase. Systematic literature reviews were conducted, quality of evidence was determined, and draft recommendations were formulated according to the Grading of Recommendations Assessment, Development, and Evaluations methodology. Recommendations that reached 80% consensus among a voting panel were finalized. Three principles and 21 recommendations were determined. Recommendations 1 and 2 pertain to treatment strategies, regular disease status assessment, and rheumatologist-steered multidisciplinary management. Recommendations 3 and 4 strongly recommend patient education, exercise, and smoking cessation. Recommendations 5-12 address pharmacological treatment of active disease using nonsteroidal anti-inflammatory drugs, glucocorticoids, sulfasalazine, biologics, and Janus kinase inhibitors. Recommendations 13-16 address treatment in stable disease. We suggest against spa and acupuncture as therapies (Recommendation 17). Recommendations 18 and 19 pertain to total hip arthroplasty and spinal surgery. Monitoring of comorbidities and drug toxicities are recommended (Recommendations 20 and 21). Recommendations for axSpA treatment in a Korean context were developed based on comprehensive clinical questions and evidence. These are intended to guide best practice in the treatment of axSpA.

Evaluating the Impact of High Intensity Interval Training on Axial Psoriatic Arthritis Based on MR Images. Diagnostics (Basel) 2022; 12:diagnostics12061420.

Abstract
High intensity interval training (HIIT) has been shown to benefit patients with psoriatic arthritis (PsA). However, magnetic resonance (MR) imaging has uncovered bone marrow edema (BME) in healthy volunteers after vigorous exercise. The purpose of this study was to investigate MR images of the spine of PsA patients for changes in BME after HIIT. PsA patients went through 11 weeks of HIIT (N = 19, 4 men, median age 52 years) or no change in physical exercise habits (N = 20, 8 men, median age 45 years). We acquired scores for joint affection and pain and short tau inversion recovery (STIR) and T1-weighted MR images of the spine at baseline and after 11 weeks. MR images were evaluated for BME by a trained radiologist, by SpondyloArthritis Research Consortium of Canada (SPARCC) scoring, and by extraction of textural features. No significant changes of BME were detected in MR images of the spine after HIIT. This was consistent for MR image evaluation by a radiologist, by SPARCC, and by texture analysis. Values of textural features were significantly different in BME compared to healthy bone marrow. In conclusion, BME in spine was not changed after HIIT, supporting that HIIT is safe for PsA patients.

Abstract
Selection of appropriate biomarker to identify inflammatory skin diseases is complicated by the involvement of thousands of differentially expressed genes (DEGs) across multiple cell types and organs. This study aimed to identify combinatorial biomarkers in inflammatory skin diseases. From one gene expression microarray profiling dataset, we performed bioinformatic analyses on dataset from lesional skin biopsies of patients with inflammatory skin diseases (atopic dermatitis [AD], contact eczema [KE], lichen planus [Li], psoriasis vulgaris [Pso]) and healthy controls to identify the involved pathways, predict upstream regulators, and potential measurable extracellular biomarkers. Overall, 434, 629, 581, and 738 DEGs were mapped in AD, KE, Li, and Pso, respectively; 238 identified DEGs were shared among four different inflammatory skin diseases. Bioinformatic analysis on four inflammatory skin diseases showed significant activation of pathways with known pathogenic relevance. Common upstream regulators, with upregulated predicted activity, identified were CNR1 and BMP4. We found the following common serum biomarkers: ACR, APOE, ASIP, CRISP1, DKK1, IL12B, IL9, MANF, MDK, NRTN, PCSK5, and VEGFC. Considerable differences of gene expression changes, involved pathways, upstream regulators, and biomarkers were found in different inflammatory skin diseases. Integrated bioinformatic analysis identified 12 potential common biomarkers of inflammatory skin diseases requiring further evaluation.

Abstract
Spondyloarthritis Research Consortium Canada (SPARCC) score is an effective magnetic resonance imaging (MRI) evaluation method for inflammation in axial spondyloarthritis. Previously published meta-analyses have shown tumor necrosis factor α inhibitors (TNFi) had great effectiveness on improving disease activity and function in axial spondyloarthritis. However, there still has no one that concentrates on the impact of TNFi on MRI inflammation. We conduct a meta-analysis to summarize the impact of TNFi on MRI inflammation in axial spondyloarthritis using SPARCC score. Comprehensive search was conducted in the databases of OVID Medline, OVID EMBASE, and Cochrane library on November 14, 2020. We investigated the differences in SPARCC score of sacroiliac joint and spine, before and after TNFi treatment in patients with axial spondyloarthritis. SPARCC score was further compared in the subgroup by diagnostic category and TNFi types. In addition, clinical assessment indicators including ankylosing spondylitis disease activity score, bath ankylosing spondylitis disease activity index, bath ankylosing spondylitis functional index, c-reactive protein were also analyzed. Data were pooled by mean differences (MD) with 95% confidence intervals (CI) and publication bias was assessed by Egger's test. Jadad scale was applied to assess the quality of included trials. Compared with control group, TNFi significantly improved SPARCC score of sacroiliac joints (n = 11, MD = 2.86, 95% CI 2.50, 3.23) and spine (n = 5, MD = 1.87,95%CI 1.27, 2.46). This effect was consistent among subgroups by different diagnostic category (ankylosing spondylitis, non-radiographic axial spondyloarthritis) and TNFi types (adalimumab, certolizumab pegol). Analysis of clinical assessment indicators also confirmed the therapeutic effect on axial spondyloarthritis. Egger's test suggested no possibility of publication bias. This meta-analysis shows that TNFi are effective to improve MRI inflammation in patients with axial spondyloarthritis and the treatment effectiveness is not affected by diagnostic category and TNFi types.

Abstract
BACKGROUND Ankylosing spondylitis (AS) is a form of rheumatic disease caused by chronic inflammation of the axial skeleton. Patients with AS experience significant functional limitations and reduced quality of life. Consequently, AS imposes a substantial economic burden on society due to productivity loss and work disability. Biologics, including tumor necrosis factor (TNF) inhibitors and human anti-interleukin-17A monoclonal antibody (IL-17A) agents, are effective treatment strategies in relieving symptoms and slowing down disease progression. Currently, 5 TNF inhibitors and 2 IL-17A antibody agents are approved by the FDA for the management of AS. Of these agents, there is no clear preferred agent in initial biologic therapy, although an IL-17A antibody agent or alternative TNF inhibitor agent is recommended after failure of the initial TNF inhibitor therapy. OBJECTIVE To assess cost-effectiveness of treatment strategies with biologics, TNF inhibitor or IL-17A, in accordance with the treatment guidelines for patients with AS. METHODS An economic patient-level simulation combining decision-tree and Markov models was constructed from the U.S. health care payer's perspective over a 10-year time horizon. The current model examined 5 treatment strategies: (1) conventional care treatment with nonsteroidal anti-inflammatory drugs, (2) 1 TNF inhibitor, (3) an IL-17A antibody agent, (4) sequential therapy with 2 TNF inhibitors, and (5) sequential therapy with a TNF inhibitor followed by an IL-17A antibody agent. Initially, treatment responses were determined after 12-week treatments. Patients who responded to treatment entered a "responders" Markov model. Patients entered a "nonresponders" Markov model if they inadequately responded to treatment. In sequential treatment strategies, patients who inadequately responded to treatment with the first TNF inhibitor received a second TNF inhibitor or an IL-17A antibody agent. Health utility was estimated based on the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and Functional Index (BASFI) scores. The models accounted for real-world adherence to TNF inhibitor treatment. Scenario and probabilistic sensitivity analyses were performed to test the robustness and uncertainty of the model results. RESULTS Over a 10-year time horizon and 100,000 simulated patients for each treatment strategy, base-case results produced average total discounted per-patient costs of $19,765, $130,302, $159,934, $190,553, and $179,118 and quality-adjusted life-years (QALYs) of 4.675, 5.410, 5.499, 5.919, and 5.893 for conventional care, treatment strategies with 1 TNF inhibitor, an IL-17A, 2 TNF inhibitors, and a TNF inhibitor followed by an IL-17A, respectively. The optimal treatments at willingness-to-pay (WTP) thresholds ≤ $130,813 per QALY, between $130,813 per QALY and $442,728 per QALY, and > $442,728 per QALY were conventional care and sequential treatment strategies with 1 TNF inhibitor, followed by an IL-17A agent and 2 TNF inhibitors, respectively. CONCLUSIONS Study findings suggested that all treatment strategies with biologics, TNF inhibitors or IL-17A antibody agents, in the treatment guidelines for AS were not cost-effective at the common WTP of $100,000 per QALY. However, the sequential treatment with 1 TNF inhibitor followed by an IL-17A antibody agent was considered cost-effective at a higher WTP of $150,000 per QALY. DISCLOSURES No outside funding supported this study. The authors have nothing to disclose. Primary findings of this study were presented in part at the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) in Baltimore, MD, May 2018.

Assessing the effect of interventions for axial spondyloarthritis according to the endorsed ASAS/OMERACT core outcome set: a meta-research study of trials included in Cochrane reviews. Arthritis Res Ther 2020; 22:177. [PMID: 32711571 PMCID: PMC7382035 DOI: 10.1186/s13075-020-02262-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Accepted: 07/06/2020] [Indexed: 12/24/2022] Open
Abstract
The Assessment of SpondyloArthritis international Society (ASAS) has defined core sets for (i) symptom-modifying anti-rheumatic drugs (SM-ARD), (ii) clinical record keeping, and (iii) disease-controlling anti-rheumatic therapy (DC-ART). These include the following domains for all three core sets: “physical function,” “pain,” “spinal mobility,” “spinal stiffness,” and “patient’s global assessment” (PGA). The core set for clinical record keeping further includes the domains “peripheral joints/entheses” and “acute phase reactants,” and the core set for DC-ART further includes the domains “fatigue” and “spine radiographs/hip radiographs.” The Outcome Measures in Rheumatology (OMERACT) endorsed the core sets in 1998. Using empirical evidence from axSpA trials, we investigated the efficacy (i.e., net benefit) according to the ASAS/OMERACT core outcome set for axSpA across all interventions tested in trials included in subsequent Cochrane reviews. For all continuous scales, we combined data using the standardized mean difference (SMD) to meta-analyze outcomes involving the same domains. Also, through meta-regression analysis, we examined the effect of the separate SMD measures (independent variables) on the primary endpoint (log [OR], dependent variable) across all trials. Based on 11 eligible Cochrane reviews, from these, 85 articles were screened; we included 43 trials with 63 randomized comparisons. Mean (SD) number of ASAS/OMERACT core outcome domains measured for SM-ARD/physical therapy trials was 4.2 (1.7). Six trials assessed all proposed domains. Mean (SD) for number of core outcome domains for DC-ART trials was 5.8 (1.7). No trials assessed all nine domains. Eight trials (16%) were judged to have inadequate (i.e., high risk of) selective outcome reporting bias. The most responsible core domains for achieving success in meeting the primary objective per trial were pain, OR (95% CI) 5.19 (2.28, 11.77), and PGA, OR (95% CI) 1.87 (1.14, 3.07). In conclusion, selective outcome reporting (and “missing data”) should be reduced by encouraging the use of the endorsed ASAS/OMERACT outcome domains in clinical trials. Overall outcome reporting was good for SM-ARD/physical therapy trials and poor for DC-ART trials. Our findings suggest that both PGA and pain provide a valuable holistic construct for the assessment of improvement beyond more objective measures of spinal inflammation.

Biologic disease-modifying anti-rheumatic drugs and patient-reported outcomes in axial SpA: a systematic review and a call for action. Clin Rheumatol 2020; 40:33-41. [PMID: 32533340 DOI: 10.1007/s10067-020-05209-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2020] [Revised: 05/26/2020] [Accepted: 05/28/2020] [Indexed: 12/17/2022]
Abstract
This paper is to assess the efficacy of different biologic DMARDs (bDMARDs) on several patient-reported outcomes (PROs) in randomized controlled trials (RCT) in axial spondyloarthritis (axSpA). A systematic literature review (SLR) was performed. MEDLINE (May 1, 2018) was used with the filters "published in the last 10 years" and "humans." The PICO criteria used were Patients: adults with radiographic axSpA (r-axSpA) or non-radiographic axSpA (nr-axSpA); Intervention: any bDMARD; Compararator: placebo (PBO)/any different drug; Outcome: the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), the Ankylosing Spondylitis Quality of Life (ASQoL), the EuroQol-5D (EQ-5D), the Short Form 36 Health Survey physical component summary (SF36-PCS), the Short Form 36 Health Survey mental component summary (SF36-MCS), and the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F). After screening 84 initial references and manually selecting other 9, 24 publications, assessing TNF inhibitors (TNFi) or IL17A inhibitors (IL17Ai) were selected. Four RCTs quantified the minimal clinical important difference (MCID) between treatment arms. Most of the RCTs compared the mean difference of PROs between different timepoints. Overall, the treatment arm was superior to the comparator. PROs were often underreported or highly heterogeneously presented. MCID was seldom mentioned. There is a need to raise the standard of care on SpA by aiming at remission and PRO associated improvements. In order to achieve this goal, the target must be clearly defined, reported, and tested.

Abstract
Axial spondyloarthritis (axSpA) is a complex disease that affects the joints and entheses of axial and peripheral joints, and is associated with inflammation in extra-articular sites such as the gut. Improved knowledge on genetics and immunology has improved treatment options with the availability of treatments targeting tumor necrosis factor-α (TNF-α) and interleukin (IL)-17. However, these agents do not provide clinical benefit for about 40% of patients, and additional therapeutic options are necessary. Theories on pathogenesis includes misfolding of HLA-B*27 during its assembly leading to endoplasmic reticulum stress and autophagy/unfolded protein response (UPR). HLA-B*27 may express free heavy chain on the cell surface, which activates innate immune receptors on T, natural killer, and myeloid cells with pro-inflammatory effects. Activation of UPR genes is associated with increased TNF-α, interleukin-23 (IL-23), IL-17, interferon-γ expression, and expansion of T helper (Th)-17 cells. Certain genotypes of endoplasmic reticulum aminopeptidase (ERAP) 1 and 2 are associated with ankylosing spondylitis (AS) and functionally interact with the HLA-B27 peptidome. Innate immune cells type 3, which express RORγt, regulate expression of IL-17 and IL-22 in T cells. Stimulation of gamma-delta T cells with IL-23 also induces IL-17. Mucosa-associated invariant T cells residing in the gut mucosa express IL-17 in AS patients after stimulation with IL-7. Prostaglandin E2 induces IL-17A independent of IL-23 via IL-1β and IL-6. The pathogenic role of gut inflammation, zonulin and microbiota, which has a different composition in AS patients, remains to be elucidated. This article also includes a comprehensive review on the mechanism of action and efficacy of the biological treatments currently approved for axSpA (TNF-α inhibitors and IL-17 inhibitors) and future targets for treatment (other IL-17 family member (s), Janus kinase, IL-23, and phosphodiesterase 4).

Abstract
Ankylosing spondylitis (AS) is a form of arthritis that can lead to fusion of vertebrae and sacroiliac joints following syndesmophyte formation. The etiology of this painful disease remains poorly defined due to its complex genetic background. There are no commonly accepted methods for early diagnosis of AS, nor are there any effective or efficient clinical treatments. Several noncoding RNAs (ncRNAs) have been linked to AS pathogenesis and inflammation via selective binding of their downstream targets. However, major gaps in knowledge remain to be filled before such findings can be translated into clinical treatments for AS. In this review, we outline recent findings that demonstrate essential roles of ncRNAs in AS mediated via multiple signaling pathways such as the Wnt, transforming growth factor-β/bone morphogenetic protein, inflammatory, T-cell prosurvival, and nuclear factor-κB pathways. The summary of these findings provides insight into the molecular mechanisms by which ncRNAs can be targeted for AS diagnosis and the development of therapeutic drugs against a variety of autoimmune diseases.

Abstract
OBJECTIVE. Accurate and reproducible MRI assessment of the sacroiliac joint (SIJ) is challenging. Numerous scoring systems have been proposed to facilitate consistent SIJ assessment. The purpose of this article is to evaluate the diagnostic accuracy and reliability of existing MRI-based SIJ scoring systems for the evaluation of spondyloarthropathy. CONCLUSION. Among existing methods, there is fair (grade B) evidence to recommend the Spondyloarthropathy Research Consortium of Canada scoring systems as tools for MRI evaluation of the SIJ. However, limited data on criterion validity limit assessment of scoring system accuracy.

Abstract
Introduction Ankylosing spondylitis (AS) is a chronic inflammatory disease characterised by new bone formation, and Dickkopf homologue 1 (Dkk-1) may contribute to the ankylosis of the sacroiliac joint as a main regulator of the Wingless (Wnt) pathway. Increasing evidence shows that microRNAs targeting Dkk-1 might play a critical role in the pathogenesis of rheumatic diseases. We aim to investigate alterations in expression of miRNAs targeting Dkk-1 in AS patients in this study. Material and methods The peripheral blood mononuclear cells (PBMCs) of 20 AS patients and 20 normal controls were collected in our study. Three miRNAs targeting DKK1 including miR-29a, miR-335, and miR-363 were selected and quantitative real-time PCR was used to identify the expression of the three miRNAs in these samples. Correlation analysis was conducted between altered miRNA expression and erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Function Index (BASFI), and mSASSS (modified Stoke Ankylosing Spondylitis Spinal Score). Results The expression of miR-29a was significantly higher in AS patients than in healthy controls (p < 0.01), while no significance was observed in the expression of miR-335 and miR-363 between AS patients and healthy controls (p > 0.05). No correlation was observed between miR-29a and ESR, CRP, BASDAI, and BASFI (p > 0.05). The elevated miR-29a expression was correlated with disease duration and mSASSS (p < 0.05). Conclusions MiR-29a might be a useful marker in AS new bone formation and contributes to the regulation of Dkk-1 in Wnt signalling.

Abstract
BACKGROUND Efficacy of anti-tumor necrosis factor (anti-TNF)α treatment in patient with active ankylosing spondylitis (AS) had been proved by many clinical studies. Inflammation and new bone formation in spine were two pivotal aspects in AS. TNF α inhibitor could eliminate inflammation including clinical and laboratory inflammatory manifestation. Paradoxical results whether TNF α antagonist could delay radiographic progression in AS were often been reported simultaneously. OBJECTIVES To review the literature about the effect of TNF α inhibitor on radiographic progression and disease activity in patient with AS. METHODS We conducted a comprehensive search including Medline, EMBASE and the Cochrane Library from 1 January 2000 to 15 August 2017. Two reviewers independently supplemented with hand searching for the reference lists of inclusion. All trials focusing on radiographic progression or disease activity in patients with AS treated with anti-TNF α agents. Primary outcomes were modified Stokes AS Spinal Score (mSASSS), as well as Bath AS disease activity index (BASDAI) and Bath AS functional index (BASFI). Two reviewers independently selected studies and analyzed data. Methodological quality was assessed using the Newcastle-Ottawa scale (NOS). We pooled effects recorded on different scales as Standardized mean differences (SMDs) with 95% confidence intervals (CIs) using random-effects models. RESULTS We included 14 studies of low to moderate risk of bias with 3,186 patients, compared with control group, there was no effect of mSASSS changes (SMD = -0.12, 95% CI: -1.17-0.93, p value = .82, I2 = 95%) and follow-up (SMD = 0.03, 95% CI: 0.21-0.26, p value = .82, I2 = 36%) estimation in anti-TNF α group. However anti-TNF α agent treatment led to remarkable improvements on both Bath AS disease activity index (BASDAI) (SMD = 1.06, 95% CI: 0.22-1.89, p value = .01, I2 = 96%) and Bath AS functional index (BASFI) (SMD = 0.93, 95% CI: 0.24-1.92, p value = .01, I2 = 97%) scores at 12 weeks. CONCLUSION Our meta-analysis found no significant effect on delaying radiographic progression in AS treated with TNF α inhibitor, although TNF α inhibitor could do improve significantly disease activity and physical function in AS.

Abstract
Objective Matching-adjusted indirect comparison was used to assess the comparative effectiveness of secukinumab 150 mg and adalimumab 40 mg in biologic-naïve patients with ankylosing spondylitis (AS) for up to 1 year. Methods Pooled individual patient data from the secukinumab arms of MEASURE 1 (NCT01358175) and MEASURE 2 (NCT01649375) trials (n=197) were matched against the ATLAS (NCT00085644) adalimumab population (n=208). Logistic regression analysis was used to determined weights to match for age, sex, Bath AS Functional Index, C-reactive protein levels, and previous tumor necrosis factor inhibitor therapy. Recalculated Assessment of SpondyloArthritis International Society (ASAS) 20 and 40 responses at weeks 8, 12, 16, 24, and 52 from MEASURE 1/2 (effective sample size=120) were compared with those of ATLAS. Anchored (placebo-adjusted) comparisons were possible until week 12, and unanchored (non-placebo-adjusted) comparisons were necessary thereafter. Results For placebo-anchored ASAS 20 and 40 comparisons up to week 12, there were no differences between secukinumab and adalimumab. For unanchored comparisons at week 16, ASAS 20 was higher for secukinumab [odds ratio 1.60 (95% confidence interval, 1.01–2.54); p=0.047]; at week 24, ASAS 20 and 40 were higher for secukinumab [1.76 (1.11–2.79); p=0.017 and 1.79 (1.14–2.82); p=0.012, respectively]; and at week 52, ASAS 40 was higher for secukinumab [1.54 (1.06–2.23); p=0.023] than for adalimumab. Conclusion There were no differences observed in placebo-adjusted ASAS 20 and 40 responses up to 12 weeks between secukinumab- and adalimumab-treated patients with ankylosing spondylitis. After week 12, secukinumab demonstrated signs of greater improvement in non-placebo-adjusted ASAS 20 and 40 responses than adalimumab.

Abstract
OBJECTIVE To compare the efficacy of 6 tumor necrosis factor-α inhibitors (TNFi) in treatment of ankylosing spondylitis (AS) at 12 weeks and 24 weeks. METHODS We performed a systematic literature review of randomized controlled trials of TNFi in patients with active AS. We included trials that reported efficacy at 10 to 14 weeks (12-week analysis) and at 24 to 30 weeks (24-week analysis). We used Bayesian network metaanalysis (NMA) to compare their relative efficacy to improve the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Bath Ankylosing Spondylitis Functional Index (BASFI), and C-reactive protein (CRP) level. RESULTS We included 20 trials of 6 TNFi, with 43 treatment arms and 3220 participants. All TNFi were significantly better than placebo in reducing BASDAI and BASFI at 12 weeks and 24 weeks; all but certolizumab pegol (CZP) were statistically better than placebo in reducing CRP at 12 weeks; all but CZP and infliximab-dyyb (IFX biosimilar) were significantly better than placebo in reducing CRP at 24 weeks. IFX was superior to the other TNFi in decreasing BASDAI at 12 weeks, but not at 24 weeks. Excluding 1 open-label trial, there were no differences among TNFi. CONCLUSION Based on this NMA of clinical trials, IFX was superior to other TNFi in reducing BASDAI at 12 weeks, but sensitive to inclusion of an open-label trial, and its efficacy was diminished at 24 weeks. The analysis was limited by few direct comparison trials. Further study of relative safety and longterm effectiveness will help inform the choice of TNFi in treating active AS.

Abstract
INTRODUCTION Golimumab is a tumor necrosis factor-α (TNF-α) inhibitor for treatment of patients with severe, active ankylosing spondylitis. This study evaluated the cost-effectiveness of golimumab compared with conventional care and other TNF-α inhibitors in treatment of AS from the UK National Health Service perspective. METHODS A long-term Markov model (with initial decision tree) was developed to simulate the progression of a hypothetical cohort of patients with active AS over a lifetime. The effectiveness outcome was quality-adjusted life-years (QALYs). Utilities were estimated by mapping Bath Ankylosing Spondylitis Functional Index scores, and the primary response measure was ≥50% improvement on the Bath Ankylosing Spondylitis Disease Activity Index at 12 weeks. Direct, medication, and AS management costs were included. Costs and outcomes were discounted at 3.5%. RESULTS All TNF-α inhibitors were comparable to each other and superior to conventional care. The incremental cost-effectiveness ratios (ICERs) for TNF-α inhibitors were £19,070-42,532 per QALY gained compared with conventional care. Analyses of the ICERs for each TNF-α inhibitor compared with conventional care demonstrated that golimumab was the most cost-effective treatment, and that adalimumab and etanercept were dominated by golimumab. Sensitivity analyses confirmed the robustness of these analyses. CONCLUSIONS Golimumab may be considered a cost-effective treatment alternative for patients with active AS. With comparable costs and efficacy among TNF-α inhibitors, the choice of TNF-α inhibitor to treat AS is likely to be driven by patient and physician choice. FUNDING Merck & Co., Inc.

Abstract
RATIONALE Renal complications in ankylosing spondylitis (AS) were rarely observed, and proteinuria associated with AS can be seen often due to amyloidosis in this kind of complications, while membranous nephropathy (MN) is seldom considered. This article reports a case of coexistence of AS and MN, to provide the exact relationship of these 2 entities and recognized some causes of renal involvement in AS. PATIENT CONCERNS A 44-year-old female presented with pain of the left leg for 4 years and pedal edema for 2 weeks. DIAGNOSES AS was diagnosed according to the patient's clinical manifestation and sacroiliitis observed on computed tomography (CT) scan. Nephrotic syndrome was found and MN was diagnosed according to kidney biopsy in which thickened capillary loops were observed with light microscopy, granular deposits of IgG along the capillary wall were observed using immunofluorescence staining, and subepithelial electron-dense deposits were observed with electron microscopy. No other secondary causes of MN were found on extensive investigations. INTERVENTION Given the diagnoses, the patient received nonimmunosuppressive therapy for MN and adalimumab for AS. OUTCOMES The patient got pain relief, as well as urinary protein reduction. LESSONS This case suggested a secondary MN in association with AS and the relationship between these 2 diseases needed more concern and further illumination.

Abstract
It has been controversial whether ankylosing spondylitis (AS) and nonradiographic axial spondyloarthritis (nr-axSpA) are separate or different phases of radiographic progression. We determined that serum calprotectin level (ng/ml) was higher in AS (15.30 ± 6.49) and nr-axSpA (17.76 ± 8.59) patients than in healthy individuals (7.40 ± 2.67). No difference was observed in calprotectin level between these two groups. Elevated calprotectin was positively correlated with ESR, CRP, BASDAI, and ASDAS as well as SPARCC scoring and had no correlation with BASFI and mSASSS. No correlation was observed between calprotectin and Wnt/β-catenin pathway markers. Serum calprotectin can be used as a marker for inflammation in both nr-axSpA and AS, while it does not contribute to the discrimination of AS and nr-axSpA. Calprotectin-mediated inflammation was not correlated with principle effectors of Wnt/β-catenin pathway, indicating that inflammation and bone fusion might be separate processes of the disease.

Abstract
BACKGROUND Tumour necrosis factor (TNF)-α inhibitors (anti-TNFs) are typically used when the inflammatory rheumatologic diseases ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-AxSpA) have not responded adequately to conventional therapy. Current National Institute for Health and Care Excellence (NICE) guidance recommends treatment with adalimumab, etanercept and golimumab in adults with active (severe) AS only if certain criteria are fulfilled but it does not recommend infliximab for AS. Anti-TNFs for patients with nr-AxSpA have not previously been appraised by NICE. OBJECTIVE To determine the clinical effectiveness, safety and cost-effectiveness within the NHS of adalimumab, certolizumab pegol, etanercept, golimumab and infliximab, within their licensed indications, for the treatment of severe active AS or severe nr-AxSpA (but with objective signs of inflammation). DESIGN Systematic review and economic model. DATA SOURCES Fifteen databases were searched for relevant studies in July 2014. REVIEW METHODS Clinical effectiveness data from randomised controlled trials (RCTs) were synthesised using Bayesian network meta-analysis methods. Results from other studies were summarised narratively. Only full economic evaluations that compared two or more options and considered both costs and consequences were included in the systematic review of cost-effectiveness studies. The differences in the approaches and assumptions used across the studies, and also those in the manufacturer's submissions, were examined in order to explain any discrepancies in the findings and to identify key areas of uncertainty. A de novo decision model was developed with a generalised framework for evidence synthesis that pooled change in disease activity (BASDAI and BASDAI 50) and simultaneously synthesised information on function (BASFI) to determine the long-term quality-adjusted life-year and cost burden of the disease in the economic model. The decision model was developed in accordance with the NICE reference case. The model has a lifetime horizon (60 years) and considers costs from the perspective of the NHS and personal social services. Health effects were expressed in terms of quality-adjusted life-years. RESULTS In total, 28 eligible RCTs were identified and 26 were placebo controlled (mostly up to 12 weeks); 17 extended into open-label active treatment-only phases. Most RCTs were judged to have a low risk of bias overall. In both AS and nr-AxSpA populations, anti-TNFs produced clinically important benefits to patients in terms of improving function and reducing disease activity; for AS, the relative risks for ASAS 40 ranged from 2.53 to 3.42. The efficacy estimates were consistently slightly smaller for nr-AxSpA than for AS. Statistical (and clinical) heterogeneity was more apparent in the nr-AxSpA analyses than in the AS analyses; both the reliability of the nr-AxSpA meta-analysis results and their true relevance to patients seen in clinical practice are questionable. In AS, anti-TNFs are approximately equally effective. Effectiveness appears to be maintained over time, with around 50% of patients still responding at 2 years. Evidence for an effect of anti-TNFs delaying disease progression was limited; results from ongoing long-term studies should help to clarify this issue. Sequential treatment with anti-TNFs can be worthwhile but the drug survival response rates and benefits are reduced with second and third anti-TNFs. The de novo model, which addressed many of the issues of earlier evaluations, generated incremental cost-effectiveness ratios ranging from £19,240 to £66,529 depending on anti-TNF and modelling assumptions. CONCLUSIONS In both AS and nr-AxSpA populations anti-TNFs are clinically effective, although more so in AS than in nr-AxSpA. Anti-TNFs may be an effective use of NHS resources depending on which assumptions are considered appropriate. FUTURE WORK RECOMMENDATIONS Randomised trials are needed to identify the nr-AxSpA population who will benefit the most from anti-TNFs.

The role of Dickkopf-1 in joint remodeling and fibrosis: A link connecting spondyloarthropathies and scleroderma? Semin Arthritis Rheum 2016; 46:430-438. [PMID: 27670695 DOI: 10.1016/j.semarthrit.2016.08.014] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2016] [Revised: 08/08/2016] [Accepted: 08/18/2016] [Indexed: 12/17/2022]
Abstract
BACKGROUND Dickkopf-1 (Dkk-1) is a soluble inhibitor of the canonical Wnt pathway, which plays critical roles in embryonic development. Evidence suggests that this molecule regulates several aspects of both bone biology and fibrosis. OBJECTIVES To provide an overview of our current knowledge of the role of Dkk-1 in joint remodeling and fibrosis. METHODS We performed an electronic search (Medline) using the following key words: Dickkopf-1 (or Dkk-1), new bone formation, joint remodeling, ankylosing spondylitis, systemic sclerosis (or scleroderma), and fibrosis, supplemented by a manual search of references from retrieved articles. RESULTS Dkk-1 is a master regulator of joint remodeling in animal models of arthritis shifting the balance toward new bone formation when its expression is decreased and toward erosion/joint destruction when its expression is increased. In humans, evidence suggests that Dkk-1 may be dysfunctional in patients with ankylosing spondylitis, a prototype bone forming disease. Moreover, data from animal models indicate that Dkk-1 has a protective role against fibrosis in several organs. Recent data suggest that inhibiting the canonical Wnt pathway by overexpression of Dkk-1 could be a way to target TGF-β signaling in fibrotic diseases. Finally, B-cell depletion therapy in systemic sclerosis may exert its effects through TGF-β dependent upregulation of Dkk-1. CONCLUSIONS Dkk-1 appears to play a crucial role in both joint remodeling/ectopic ossification and fibrosis, and may be a prospective therapeutic modality for fibrotic diseases or diseases characterized by pathologic joint remodeling.

Abstract
Objectives This study aims to determine the levels of bone turnover markers in canonical wingless pathway in patients with ankylosing spondylitis (AS) and the correlation with disease activity indexes. Patients and methods We recruited a total of 43 AS patients (34 males, 8 females; mean age 36.8±9.3 years; range 22 to 62 years) and age- and sex-matched 42 healthy controls (32 males, 10 females; mean age 36.1±9.7; range 24 to 59 years). Serum levels of components of canonical wingless pathway including Dickkopf-1, glycogen synthase kinase-3β, β-catenin, alkaline phosphatase, and osteocalcin were detected using enzyme- linked immunosorbent assay method. All patients were assessed in terms of erythrocyte sedimentation rate, C-reactive protein, Bath Ankylosing Spondylitis Disease Activity Index, Bath Ankylosing Spondylitis Functional Index, Ankylosing Spondylitis Disease Activity Score, and the modified Stoke's Ankylosing Spondylitis Spine Score. Pearson's correlation test was used to analyze the correlation between serum bone turnover markers and clinical assessment indexes. Results No significant difference was observed between AS patients and healthy controls for the levels of glycogen synthase kinase-3β, β-catenin, alkaline phosphatase, and osteocalcin, respectively (p>0.05). The level of Dickkopf-1 was significantly higher in AS patients (1914.5±407.8 pg/mL) than in healthy controls (1729.1±352.9 pg/mL) (p<0.05). There was no correlation between high Dickkopf-1 level and any of the clinical parameters contributing to inflammation or bone formation. However, the correlation between osteocalcin and disease duration was significant in AS patients (r=0.323, p=0.034). Conclusion Alteration of bone turnover markers in canonical wingless pathway was observed in AS. This might partially explain the complicated mechanism of bone formation in the disease.

Abstract
The Wnt signaling pathway plays a key role in many biological aspects, such as cellular proliferation, tissue regeneration, embryonic development, and other systemic effects. Under a physiological condition, it is tightly controlled at different layers and arrays, and a dysregulated activation of this signaling has been implicated into the pathogenesis of various human disorders, including autoimmune diseases. Despite the fact that therapeutic interventions are available for ameliorating disease manifestations, there is no curative therapy currently available for autoimmune disorders. Increasing lines of evidence have suggested a crucial role of Wnt signaling during the pathogenesis of many autoimmune diseases; in addition, some of microRNAs (miRNAs), a class of small, noncoding RNA molecules capable of transcriptionally regulating gene expression, have also recently been demonstrated to possess both physiological and pathological roles in autoimmune diseases by regulating the Wnt signaling pathway. This review summarizes currently our understanding of the pathogenic roles of Wnt signaling in several major autoimmune disorders and miRNAs, those targeting Wnt signaling in autoimmune diseases, with a focus on the implication of the Wnt signaling as potential biomarkers and therapeutic targets in immune diseases, as well as miRNA-mediated regulation of Wnt signaling activation in the development of autoimmune diseases.

Abstract
OBJECTIVES To summarize the characteristics of backfill in patients with axial spondyloarthritis (SpA) and patients with non-specific back pain (NSBP) and healthy controls, and to assess the value of backfill in diagnosing axial SpA. METHODS Three readers blinded recorded backfill seen on T1SE MRI scans from 647 subjects: 297 patients with ankylosing spondylitis (AS), 126 patients with non-radiographic axial SpA (nr-axSpA), 147 patients with NSBP, and 77 healthy controls. The SPARCC SIJ Structural Score (SSS) method was used to assess backfill. The changes of backfill were evaluated by the follow-up MRI scans from 157 patients. We summarized the characteristics of backfill and calculated its sensitivity and specificity for diagnosing axial SpA. RESULTS Backfill was recorded in 78.8% AS patients, 11.1% nr-axSpA patients, 1.8% patients with NSBP, and no healthy control. Backfill affected more frequently at ilium bone, lower half of sacroiliac joints in axial SpA (both P<0.05). The SSS score of backfill was much higher in axial SpA than in patients with NSBP (both P<0.01) and it did not correlate with demographics and BASDAI, BASFI, and CRP (all P>0.05). The score of backfill only positively correlated with symptom duration in AS (r=0.251, P<0.01) and in nr-axSpA (r=0.743, P<0.01) patients. Only 8.9% patients had the change of backfill in an average follow-up time of 1.09 years. Backfill had high specificity (0.98) and moderate sensitivity (0.59) for diagnosing axial SpA. CONCLUSIONS We summarized the characteristics of backfill and found that backfill is a specific sign of axial SpA seen on T1SE MRI.

Abstract
OBJECTIVES To explore the effects of serum from patients with ankylosing spondylitis on the canonical Wnt/β-catenin pathway and to assess whether the serum has an osteogenic effect in MG63 cells. METHODS MG63 cells were cultured with serum from 45 ankylosing spondylitis patients, 30 healthy controls, or 45 rheumatoid arthritis patients. The relative PPARD, fra-1, MMP7, OPG and RANKL mRNA levels were measured using quantitative real-time polymerase chain reaction. Associations between gene expression and patient demographics and clinical assessments were then analyzed. RESULTS MG63 cells treated with serum from ankylosing spondylitis patients had higher PPARD, fra-1, MMP7 and OPG gene expression than did cells treated with serum from controls or rheumatoid arthritis patients (all p<0.05). RANKL expression was higher in MG63 cells treated with serum from patients with ankylosing spondylitis or rheumatoid arthritis than in those treated with serum from controls (both p<0.05). The OPG/RANKL ratio was also higher in MG63 cells treated with serum from ankylosing spondylitis patients than in those treated with serum from controls (p<0.05). No associations were found between the expression of the five genes and the patient demographics and clinical assessments (all p>0.05). CONCLUSIONS Serum from ankylosing spondylitis patients increases PPARD, fra-1, MMP7, OPG and RANKL expression and the OPG/RANKL ratio in MG63 cells; these effects may be due to the stimulatory effect of the serum on the Wnt pathway.

Abstract
BACKGROUND TNF (tumor necrosis factor)-alpha inhibitors block a key protein in the inflammatory chain reaction responsible for joint inflammation, pain, and damage in ankylosing spondylitis. OBJECTIVES To assess the benefit and harms of adalimumab, etanercept, golimumab, and infliximab (TNF-alpha inhibitors) in people with ankylosing spondylitis. SEARCH METHODS We searched the following databases to January 26, 2009: MEDLINE (from 1966); EMBASE (from 1980); the Cochrane Central Register of Controlled Trials (CENTRAL; 2008, Issue 4); ACP Journal Club; CINAHL (from 1982); and ISI Web of Knowledge (from 1900). We ran updated searches in May 2012, October 2013, and in June 2014 for McMaster PLUS. We searched major regulatory agencies for safety warnings and clinicaltrials.gov for registered trials. SELECTION CRITERIA Randomized controlled trials (RCTs) comparing adalimumab, etanercept, golimumab and infliximab to placebo, other drugs or usual care in patients with ankylosing spondylitis, reported in abstract or full-text. DATA COLLECTION AND ANALYSIS Two authors independently assessed search results, risk of bias, and extracted data. We conducted Bayesian mixed treatment comparison (MTC) meta-analyses using WinBUGS software. To investigate a class-effect of harms across biologics, we pooled harms data using Review Manager 5. MAIN RESULTS We included twenty-one, short-term (24 weeks or less) RCTs with a total of 3308 participants; 18 contributed data to the MTC analysis: adalimumab (4 studies), etanercept (8 studies), golimumab (2 studies), infliximab (3 studies), and one head-to-head study (etanercept versus infliximab) which was unblinded and considered at a higher risk of bias. The risk of selection and detection bias was low or unclear for most of the studies. The risk of selective outcome reporting was low for most studies as they reported on outcomes recommended by the Assessment of SpondyloArthritis international Society. We found little heterogeneity and no significant inconsistency in the MTC analyses. The majority of the studies were funded by pharmaceutical companies. Most studies permitted concomitant therapy of stable doses of disease-modifying anti-rheumatic drugs, non-steroidal anti-inflammatory drugs, or corticosteroids, but allowances varied across studies.Compared with placebo, there was high quality evidence that patients on an anti-TNF agent were three to four times more likely to achieve an ASAS40 response (assessing spinal pain, function, and inflammation, as measured by the mean of intensity and duration of morning stiffness, and patient global assessment) by six months (adalimumab: risk ratio (RR) 3.53, 95% credible interval (Crl) 2.49 to 4.91; etanercept: RR 3.31, 95% Crl 2.38 to 4.53; golimumab: RR 2.90, 95% Crl 1.90 to 4.23; infliximab: RR 4.07, 95% Crl 2.80 to 5.74, with a 25% to 40% absolute difference between treatment and placebo groups. The number needed to treat (NNT) to achieve an ASAS 40 response ranged from 3 to 5.There was high quality evidence of improvement in physical function on a 0 to 10 scale (adalimumab: mean difference (MD) -1.6, 95% Crl -2.2 to -0.9; etanercept: MD -1.1, 95% CrI -1.6 to -0.6; golimumab: MD -1.5, 95% Crl -2.3 to -0.7; infliximab: MD -2.1, 95% Crl -2.7 to -1.4, with an 11% to 21% absolute difference between treatment and placebo groups. The NNT to achieve the minimally clinically important difference of 0.7 points ranged from 2 to 4.Compared with placebo, there was moderate quality evidence (downgraded for imprecision) that patients on an anti-TNF agent were more likely to achieve an ASAS partial remission by six months (adalimumab: RR 6.28, 95% Crl 3.13 to 12.78; etanercept: RR 4.24, 95% Crl 2.31 to 8.09; golimumab: RR 5.18, 95% Crl 1.90 to 14.79; infliximab: RR 15.41, 95% Crl 5.09 to 47.98 with a 10% to 44% absolute difference between treatment and placebo groups. The NNT to achieve an ASAS partial remission response ranged from 3 to 11.There was low to moderate level evidence of a greater reduction in spinal inflammation as measured by magnetic resonance imaging though the absolute differences were small and the clinical relevance of the difference was unclear: adalimumab (1 trial; -6% (95% confidence interval (CI) -12% to 0.05%); 1 trial: 53.6% mean decrease from baseline versus 9.4% mean increase in the placebo group), golimumab (1 trial; -2.5%, (95% CI -5.6% to -0.7%)), and infliximab (1 trial; -3% (95% CI -4% to -2.4%)).Radiographic progression was measured in one trial (N = 60) of etanercept versus placebo and it found that radiologic changes were similar in both groups (detailed data not provided).There were few events of withdrawals due to adverse events leading to imprecision around the estimates. When all the anti-TNF agents were combined against placebo, there was moderate quality evidence from 16 studies of an increased risk of withdrawals due to adverse events in the anti-TNF group (Peto odds ratio (OR) 2.44, 95% CI 1.26 to 4.72; total events: 38/1637 in biologic group; 7/986 in placebo) though the absolute increase in harm was small (1%; 95% CI 0% to 2%).Due to low event rates, evidence of the effect of individual TNF-inhibitors against placebo or for all four biologics pooled together versus placebo on serious adverse events is inconclusive (moderate quality; downgraded for imprecision). For all anti-TNF pooled versus placebo based on 16 studies: Peto OR 1.45, 95% CI 0.85 to 2.48; 51/1530 in biologic group; 18/878 in placebo; absolute difference: 1% (95% CI 0% to 2%).Using indirect comparison methodology, and one head-to-head study of etanercept versus infliximab, wide confidence intervals meant that results were inconclusive for evidence of differences in the major outcomes between different anti-TNF agents. Regulatory agencies have published warnings about rare adverse events of serious infections, including tuberculosis, malignancies and lymphoma. AUTHORS' CONCLUSIONS There is moderate to high quality evidence that anti-TNF agents improve clinical symptoms in the treatment of ankylosing spondylitis. More participants withdrew due to adverse events when on an anti-TNF agent but we did not find evidence of an increase in serious adverse events, though event rates were low and trials had a short duration. The short-term toxicity profile appears acceptable. Based on indirect comparison methodology, we are uncertain whether there are differences between anti-TNF agents in terms of the key benefit or harm outcomes.

Abstract
A taskforce comprised of an expert group of 21 rheumatologists, radiologists and methodologists from 11 countries developed evidence-based recommendations on the use of imaging in the clinical management of both axial and peripheral spondyloarthritis (SpA). Twelve key questions on the role of imaging in SpA were generated using a process of discussion and consensus. Imaging modalities included conventional radiography, ultrasound, magnetic resonance imaging, computed tomography (CT), positron emission tomography, single photon emission CT, dual-emission x-ray absorptiometry and scintigraphy. Experts applied research evidence obtained from systematic literature reviews using MEDLINE and EMBASE to develop a set of 10 recommendations. The strength of recommendations (SOR) was assessed by taskforce members using a visual analogue scale. A total of 7550 references were identified in the search process, from which 158 studies were included in the systematic review. Ten recommendations were produced using research-based evidence and expert opinion encompassing the role of imaging in making a diagnosis of axial SpA or peripheral SpA, monitoring inflammation and damage, predicting outcome, response to treatment, and detecting spinal fractures and osteoporosis. The SOR for each recommendation was generally very high (range 8.9–9.5). These are the first recommendations which encompass the entire spectrum of SpA and evaluate the full role of all commonly used imaging modalities. We aimed to produce recommendations that are practical and valuable in daily practice for rheumatologists, radiologists and general practitioners.

Abstract
OBJECTIVES New bone formation is one of the hallmark characteristics of ankylosing spondylitis, which is thereby associated with syndesmophytes. Fetuin-A is a molecule that is abundantly found in calcified tissues and it shows high affinity for calcium phosphate minerals and related compounds. Considering the role of fetuin-A in the regulation of calcified matrix metabolism, we compared the fetuin-A levels in ankylosing spondylitis patients with syndesmophytes with those in patients without syndesmophytes and in healthy controls. We also studied other biomarkers that are thought to be related to syndesmophytes. METHODS Ninety-four patients (49 patients without syndesmophytes, 67.3% male, 40.7±8.7 years; 45 patients with syndesmophytes, 71.1% M, 43.9±9.9 years) and 68 healthy controls (44.2±10.6 years and 70.6% male) were included in this study. Syndesmophytes were assessed on the lateral radiographs of the cervical and lumbar spine. The serum levels of fetuin-A, dickkopf-1, sclerostin, IL-6, high-sensitivity C-reactive protein and bone morphogenetic protein-7 were measured with an enzyme-linked immunosorbent assay. RESULTS Patients with syndesmophytes had significantly higher levels of fetuin-A compared with patients without syndesmophytes and controls (1.16±0.13, 1.05±0.09 and 1.08±0.13 mg/ml, respectively). However, fetuin-A was not different between the patients without syndesmophytes and controls. Bone morphogenetic protein-7 was significantly lower; dickkopf-1 was significantly higher in patients with ankylosing spondylitis compared with controls. The sclerostin concentrations were not different between the groups. In regression analysis, fetuin-A was an independent, significant predictor of syndesmophytes. CONCLUSION Our results suggest that fetuin-A may a role in the pathogenesis of bony proliferation in ankylosing spondylitis.

Abstract
OBJECTIVES Ankylosing spondylitis (AS) is a chronic inflammatory disease characterized by new bone formation. Recent evidence suggests that new bone formation in AS may be due to upregulation of Wnt signaling in the osteoblastic pathway secondary to low serum Dickkopf homolog 1 (Dkk-1) levels. And miR-29a orchestrates osteoblast differentiation through direct targeting and negative regulation of Dkk-1. METHODS We initially validated the expression levels of miR-29a in the peripheral blood mononuclear cells (PBMCs) of AS patients (n = 30), rheumatoid arthritis (RA) patients (n = 30) and healthy controls (n = 30) using real-time quantitative reverse transcription PCR (qRT-PCR). Correlation analysis was assessed between miR-29a level in PBMCs of AS patients and disease activity indexes, including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis function index (BASFI) and modified Stoke ankylosing spondylitis spinal score (mSASSS). RESULTS Significantly higher expression of miR-29a was observed in PBMCs of AS patients (Ct 9.18 ± 1.96) compared with that in RA patients (10.97 ± 0.70, p < 0.001) and healthy controls (Ct 11.45 ± 1.23, p < 0.001). There was no significant difference between RA patients and healthy controls in miR-29a expression (p > 0.05). Elevated miR-29a expression is not correlated with disease activity index (p > 0.05). A weak correlation was found between elevated miR-29a expression and mSASSS (r = -0.393, p = 0.032). CONCLUSIONS We report for the first time elevated miR-29a expression in PBMCs of patients with ankylosing spondylitis, and miR-29a might be used as a useful diagnostic marker in new bone formation but cannot reflect disease activity.

Abstract
Ankylosing spondylitis (AS) is the most common and most severe subtype of spondyloarthritis. It also may be an outcome of any of the other spondyloarthritis subtypes. AS preferentially affects the sacroiliac joints and the tip of the column, with a tendency to later ankylosis. Peripheral joints, enthesis, and other extra-articular involvement may be observed. Tumor necrosis factor (TNF) inhibitors are now well-established, effective drugs in the treatment of AS symptoms. Adalimumab, which is a fully human monoclonal antibody that binds to and neutralizes TNF, has demonstrated efficacy in treating AS symptoms, including axial involvement, peripheral arthritis, enthesitis, uveitis, gut involvement, and psoriasis. Furthermore, adalimumab has showed an overall acceptable safety profile. In this paper, we review the efficacy and safety profile of adalimumab in the treatment of AS, and discuss its differences from the other anti-TNF drugs reported in the literature.

Abstract
The mechanisms that lead to bony fusion in ankylosing spondylitis (AS) are yet to be fully defined. In recent years, there have been several advances in our understanding of this complex disease. Here, the potential impact of the Wnt signaling pathway will be discussed. This pathway is involved in bone morphogenesis and homeostasis. Perturbations in the normal regulation have been implicated in abnormal bone formation (e.g., osteophytes). Levels of Wnt regulatory proteins like Dickkopf have been investigated as potential biomarkers of disease. This pathway might be involved in other aspects of this disease including T cell activation and differentiation, and in bone marrow adipogenesis. The pathways leading to the unique pathology and bony fusion in AS are complex and the Wnt pathway might play a critical contributing role.

Abstract
OBJECTIVES This meta-analysis investigates the efficacy of tumour necrosis factor α (TNFα) blockers versus placebo for the treatment of ankylosing spondylitis (AS) and non-radiographic axial spondyloarthritis (nr-axSpA). METHODS A systematic literature search was conducted independently by two reviewers. Double-blind randomised controlled trials (RCTs) investigating the efficacy of adalimumab, certolizumab, etanercept, golimumab or infliximab in approved dosages in comparison with placebo were included. The use of concomitant non-steroidal antirheumatic drugs was allowed. The outcome parameters were improvement in disease activity and function measured by the Bath AS disease activity index (BASDAI), Bath AS functional index (BASFI) and ASAS40 response. The effect sizes of the changes in BASDAI/BASFI between TNFα blocker and placebo comparator groups were calculated. Mixed effect models were applied separately for RCTs with AS and nr-axSpA patients and differences between those groups were evaluated in a joint model. RESULTS 20 studies with data from 3096 patients were included in the analysis: 15 studies with AS patients, four with nr-axSpA patients and one with both. For AS patients, TNFα blockers showed better efficacy than placebo for BASDAI (effect size 1.00), BASFI (effect size 0.67) and ASAS40 response (OR 4.7). For nr-axSpA patients, the differences were smaller (effect sizes 0.73, 0.57; OR 3.6). However, after adjustment for the year of publication as a proxy for disease severity, no differences in the effect sizes between the AS and nr-axSpA trials were observed. CONCLUSIONS Compared with placebo, TNFα blockers improve disease activity and functional capacity clinically meaningful for both AS and nr-axSpA patients.

Abstract
Adalimumab is a fully human, anti-TNF monoclonal antibody of proven efficacy and safety in the treatment of the signs, symptoms and functional disability of ankylosing spondylitis (AS). A systematic review and meta-analysis was performed to assess the efficacy and safety of adalimumab treatment, relative to a placebo, in adult patients with AS. In the efficacy meta-analysis, significantly more patients in the adalimumab group achieved Assessment in AS International Working Group (ASAS)20 and Bath AS Disease Activity Index (BASDAI)50 compared with patients in the placebo group. Patients in the adalimumab group also showed significant improvement in BASDAI and health-related quality of life. With regard to adverse events, any adverse events and injection-site reaction were significantly higher in the adalimumab group compared with the control group. This meta-analysis shows a higher efficacy of adalimumab relative to placebo, but clinicians should be careful regarding adverse events in adalimumab-treated patients.

Abstract
INTRODUCTION Following its marketing authorization for the treatment of ankylosing spondylitis (AS) in 2006 in the United States und in the European Union, adalimumab became one of the most frequently prescribed tumor necrosis factor (TNF) α blockers available for this indication. Recently, the label for adalimumab was extended to nonradiographic axial spondyloarthritis (nr-axSpA), which might be considered as an early stage of AS. The increasing number of patients with AS being treated with adalimumab raises issues concerning long-term safety, efficacy in the prevention of structural damage in the spine and high treatment costs. AREAS COVERED Herein, we summarize data on efficacy and safety of adalimumab treatment in AS and nr-axSpA obtained over the past 5 years. EXPERT OPINION Adalimumab is clinically effective and reasonably safe in the short-term and long-term treatment of patients with AS who do not respond to standard therapy. Recent data indicate good efficacy of adalimumab also in patients with nr-axSpA but only in the presence of objective signs of active inflammation. Yet unresolved questions relate to the ability of adalimumab to stop or retard structural damage development in the spine in patients with AS and nr-axSpA. The introduction of biosimilar drugs in the near future may potentially reduce the currently very high treatment costs associated with adalimumab treatment.
