          Abstract

          Purpose

          Non-steroidal anti-inflammatory drugs (NSAIDs) have generally been viewed as first-line therapy for axial spondyloarthritis (axSpA). Imrecoxib is a selective COX-2 inhibitor developed independently in China. At present, only one single-center RCT trial has shown that imrecoxib is equally effective as celecoxib in treating axSpA. Based on real-world data, our study aims to explore the efficiency of imrecoxib and TNF inhibitor (TNFi) combined with imrecoxib in treating axSpA.

          Patients and Methods

          A total of 163 patients with axSpA who had more than two follow-up records in 6 months and treated with imrecoxib/celecoxib/TNFi combined with imrecoxib/TNFi combined with celecoxib from the First Affiliated Hospital of Anhui Medical University SpA Real World Database (AHSpA) were selected for analysis of our study. The linear mixed model was used to compare efficacy indexes before and after treatment and between different groups, adjust baseline measurement value and follow-up time. The Kaplan–Meier survival analysis was used to identify the differences in cumulative clinical remission rates between groups with different treatment at the follow-up period.

          Results

          Results showed that after treatment ASDAScrp was slightly improved in imrecoxib group and celecoxib group within 6 months (p < 0.05). CRP, ESR, BASDAI, ASDAScrp, BASFI, occiput to wall distance and finger floor distance all significantly improved in TNFi combined with imrecoxib group and TNFi combined with celecoxib group within 6 months (all p < 0.05). According to the Kaplan–Meier survival curve and Log rank test analysis, the clinical remission rate was not significantly different between different treatment during 24-month follow-up (all p > 0.05).

          Conclusion

          ASDAScrp improved slightly within 6 months after treatment with imrecoxib, and TNFi combined with imrecoxib significantly improved multiple effect indexes in axSpA patients. The efficacy of imrecoxib and celecoxib in the treatment of axSpA is equivalent. Also, they have the same efficacy after being combined with TNFi.

          The development of Assessment of SpondyloArthritis international Society classification criteria for axial spondyloarthritis (part II): validation and final selection.

          To validate and refine two sets of candidate criteria for the classification/diagnosis of axial spondyloarthritis (SpA). All Assessment of SpondyloArthritis international Society (ASAS) members were invited to include consecutively new patients with chronic (> or =3 months) back pain of unknown origin that began before 45 years of age. The candidate criteria were first tested in the entire cohort of 649 patients from 25 centres, and then refined in a random selection of 40% of cases and thereafter validated in the remaining 60%. Upon diagnostic work-up, axial SpA was diagnosed in 60.2% of the cohort. Of these, 70% did not fulfil modified New York criteria and, therefore, were classified as having "non-radiographic" axial SpA. Refinement of the candidate criteria resulted in new ASAS classification criteria that are defined as: the presence of sacroiliitis by radiography or by magnetic resonance imaging (MRI) plus at least one SpA feature ("imaging arm") or the presence of HLA-B27 plus at least two SpA features ("clinical arm"). The sensitivity and specificity of the entire set of the new criteria were 82.9% and 84.4%, and for the imaging arm alone 66.2% and 97.3%, respectively. The specificity of the new criteria was much better than that of the European Spondylarthropathy Study Group criteria modified for MRI (sensitivity 85.1%, specificity 65.1%) and slightly better than that of the modified Amor criteria (sensitivity 82.9, specificity 77.5%). The new ASAS classification criteria for axial SpA can reliably classify patients for clinical studies and may help rheumatologists in clinical practice in diagnosing axial SpA in those with chronic back pain.

            2016 update of the ASAS-EULAR management recommendations for axial spondyloarthritis

            To update and integrate the recommendations for ankylosing spondylitis and the recommendations for the use of tumour necrosis factor inhibitors (TNFi) in axial spondyloarthritis (axSpA) into one set applicable to the full spectrum of patients with axSpA. Following the latest version of the European League Against Rheumatism (EULAR) Standardised Operating Procedures, two systematic literature reviews first collected the evidence regarding all treatment options (pharmacological and non-pharmacological) that were published since 2009. After a discussion of the results in the steering group and presentation to the task force, overarching principles and recommendations were formulated, and consensus was obtained by informal voting. A total of 5 overarching principles and 13 recommendations were agreed on. The first three recommendations deal with personalised medicine including treatment target and monitoring. Recommendation 4 covers non-pharmacological management. Recommendation 5 describes the central role of non-steroidal anti-inflammatory drugs (NSAIDs) as first-choice drug treatment. Recommendations 6–8 define the rather modest role of analgesics, and disprove glucocorticoids and conventional synthetic disease-modifying antirheumatic drugs (DMARDs) for axSpA patents with predominant axial involvement. Recommendation 9 refers to biological DMARDs (bDMARDs) including TNFi and IL-17 inhibitors (IL-17i) for patients with high disease activity despite the use (or intolerance/contraindication) of at least two NSAIDs. In addition, they should either have an elevated C reactive protein and/or definite inflammation on MRI and/or radiographic evidence of sacroiliitis. Current practice is to start with a TNFi. Switching to another TNFi or an IL-17i is recommended in case TNFi fails (recommendation 10). Tapering, but not stopping a bDMARD, can be considered in patients in sustained remission (recommendation 11). The final two recommendations (12, 13) deal with surgery and spinal fractures. The 2016 Assessment of SpondyloArthritis international Society-EULAR recommendations provide up-to-date guidance on the management of patients with axSpA.

              Axial spondyloarthritis.

              The term axial spondyloarthritis covers both patients with non-radiographic and radiographic axial spondyloarthritis, which is also termed ankylosing spondylitis. The disease usually starts in the third decade of life with a male to female ratio of two to one for radiographic axial spondyloarthritis and of one to one for non-radiographic axial spondyloarthritis. More than 90% heritabilty has been estimated, the highest genetic association being with HLA-B27. The pathogenic role of HLA-B27 is still not clear although various hypotheses are available. On the basis of evidence from trials the cytokines tumour necrosis factor (TNF)-α and interleukin-17 appear to have a relevant role in pathogenesis. The mechanisms of interaction between inflammation and new bone formation is still not completely understood but clarification will be important for the prevention of long-term structural damage of the bone. The development of new criteria for classification and for screening of patients with axial spondyloarthritis have been crucial for the early indentification and treatment of such patients, with MRI being the most important existing imaging method. Non-steroidal anti-inflammatory drugs and TNF blockers are effective therapies. Blockade of interleukin-17 is a new and relevant treatment option.
