Abstract
Objectives: To investigate the relationship between smoking and imaging outcomes over 5 years in axSpA and assess if socioeconomic (SE) factors influence these relationships.
Methods: Patients with axSpA from the DESIR cohort were included. Four imaging outcomes (spine radiographs [modified Stoke Ankylosing Spondylitis Spine Score, mSASSS]; SIJ radiographs [modified New York grading, mNY]); MRI-Spine [Spondyloarthritis Research Consortium of Canada scoring, SPARCC] and MRI-SIJ [SPARCC]) were assessed by three central readers at baseline, 2 and 5-years. Explanatory variable of interest was smoking status at baseline. Interactions between smoking and SE factors (job type [blue- vs white-collar] and education [low vs high]) were first tested and if significant, analyses were run in separate strata. Generalized estimating equations models were used, adjusted for confounders.
Results: In total, 406 axSpA patients were included: 52% male, 40% smokers and 18% blue-collar. Smoking was independently associated with more MRI-SIJ inflammation at each visit over the 5-years, an effect that was seen only in blue-collar patients (β[95% CI]:5.41 [1.35,9.48]) and in patients with low education (β[95% CI]:2.65 [0.42, 4.88] (separate model). Smoking was also significantly associated with spinal inflammation (β[95% CI]:1.69 [0.45, 2.93] and SIJ damage (β[95% CI]:0.57 [0.18, 0.96] across all patients, irrespective of SE factors and other potential confounders.
Conclusion: Strong associations were found in particular between smoking at baseline and MRI-SIJ inflammation at each visit over 5-years in axSpA patients with blue-collar job or low education. These findings suggest a possible role for mechanical stress amplifying the effect of smoking on axial inflammation in axSpA.

Un nouvel article scientifique intitulé «Effect of Gut Involvement in Patients With High Probability of Early Spondyloarthritis: Data From the DESIR Cohort» a été publié dans le journal J Rheumatol.
Daniel Wendling, Xavier Guillot, Clément Prati, Corinne Miceli-Richard, Anna Molto, Rik Lories, Maxime Dougados.
Abstract
Objective: Inflammatory bowel disease (IBD) is a well-known extraarticular feature of spondyloarthritis (SpA). The aims of this study were to evaluate factors associated with IBD and incidence over 5 years of followup in the DESIR cohort.
Methods: DESIR is a prospective observational cohort of patients with recent-onset inflammatory back pain suggestive of axial SpA. All available variables in the database were compared between patients with and without IBD at baseline and 5 years, and occurrence over 5 years of followup, with uni- and then multivariable analysis.
Results: At baseline, of 708 patients, 35 had IBD (prevalence 4.94%, CI 95% 3.3-6.5). IBD was associated (multivariable) with history of uveitis, levels of Dickkopf-1, and tumor necrosis factor, but not with phenotypic presentation (peripheral arthritis, enthesitis, dactylitis, uveitis) or baseline serum levels of other cytokines. At 5 years, 480 patients were analyzed, 58 with IBD. IBD was associated (multivariable) with fulfillment of modified New York criteria, sick leave, Bath Ankylosing Spondylitis Disease Activity Index, and smoking. There was no association with magnetic resonance imaging scores, enthesitis, psoriasis, and bone mineral density. Twenty-three incident cases of IBD were recorded: estimated occurrence rate of 0.95/100 (95% CI 0.57-1.35) patient-years (PY). Incidence of IBD is associated (multivariable) with HLA-B27 (OR 0.36, 95% CI 0.22-0.59), fulfillment of modified New York criteria (OR 3.35, 95% CI 1.85-6.08), and familial history of IBD (OR 3.31, 95% CI 1.62-6.77).
Conclusion: In early SpA, IBD occurs with an incidence of 1/100 PY, and is associated with poor outcome, familial history of IBD, absence of HLA-B27, and fulfillment of modified New York criteria.

Un nouvel article scientifique intitulé «Integrated Longitudinal Analysis Does Not Compromise Precision and Reduces Bias in the Study of Imaging Outcomes: A Comparative 5-year Analysis in the DESIR Cohort» a été publié dans le journal Semin Arthritis Rheum.
1. Alexandre Sepriano, Sofia Ramiro, Désirée van der Heijde, Maxime Dougados, Pascal Claudepierre , Antoine Feydy, Monique Reijnierse, Damien Loeuille, Robert Landewé.
Abstract
Objective:
To assess if an integrated longitudinal analysis using all available imaging data affects the precision of estimates of change in patients with axial spondyloarthritis (axSpA), with completers analysis as reference standard.
Methods:
Patients from the DESIR cohort fulfilling the ASAS axSpA criteria were included. Radiographs and MRIs of the sacroiliac joints and spine were obtained at baseline, 1, 2 and 5 years. Each image was scored by 2 or 3 readers in 3 ‘reading-waves’ (or campaigns). Each outcome was analyzed: i. According to a ‘combination algorithm’ (e.g. ‘2 out of 3′ for binary scores); and ii. Per reader. Change over time was analyzed with generalized estimating equations by 3 approaches: (a)’integrated-analysis’ (all patients with ≥1 score from ≥1 reader from all waves); (b1)Completers-only analysis (patients with 5-year follow-up, using scores from individual readers); (b2)Completers analysis using a ‘combination algorithm’ (as (b1) but with combined scores). Approaches (b1) and (b2) were considered the ‘reference’.
Results:
In total, 413 patients were included. The ‘integrated analysis’ was more inclusive with similar levels of precision of the change estimates as compared to both completers analyses. In fact, for low-incident outcomes (e.g.% mNY-positive over 5-years), an increased incidence was ‘captured’, with more precision, by the ‘integrated analysis’ compared to the completers analysis with combined scores (% change/year (95%CI): 1.1 (0.7; 1.5) vs 1.2 (0.5; 1.8), respectively).
Conclusion:
An efficient and entirely assumption-free ‘integrated analysis’ does not jeopardize precision of the estimates of change in imaging parameters and may yield increased statistical power for detecting changes with low incidence.

Un nouvel article scientifique intitulé «5-year Follow-Up of Spinal and Sacroiliac MRI Abnormalities in Early Axial Spondyloarthritis: Data From the DESIR Cohort» a été publié dans le journal RMD Open.
Queeny Madari , Alexandre Sepriano, Sofia Ramiro, Anna Molto, Pascal Claudepierre, Daniel Wendling, Maxime Dougados, Desirée van der Heijde, Floris A van Gaalen.
Abstract
Objective:
To study changes on MRI of the spine and sacroiliac joint (SIJ) in early axial spondyloarthritis (axSpA) over time.
Methods:
In the Devenir des Spondyloarthropathies Indifférenciées Récentes cohort, MRI-spine and MRI-SIJ at baseline and 2 and 5 years were scored by central readers for bone marrow oedema (BME), fatty lesions, erosions, sclerosis, ankylosis and spinal bone spurs. The average mean number of lesions was reported or the agreement of ≥2 out of 3 readers for binary outcomes. Net progression was calculated by subtracting the patients that ‘improved’ from those that ‘worsened’ divided by the total number of patients.
Results:
Over 5 years, in 155 patients with axSpA (mean age 33.5 (SD 8.9) years, symptom duration 1.4 (0.8) years, 63% human leucocyte antigen+, 14% modified New York+), BME on MRI-SIJ decreased by a mean Spondyloarthritis Research Consortium of Canada score of 1.4 (SD 6.5) (p=0.009). The largest BME decrease was observed in patients using biological disease-modifying antirheumatic drugs at 5 years. Spinal BME increased by 0.3 (4.6) (p=0.41). Fatty lesions and/or erosions on MRI-SIJ increased by a mean of 1.0 (SD 2.6) (p<0.001). Spinal fatty lesions and/or erosions increased by 0.2 (SD 0.5) (p<0.001). Compared with baseline, at 5 years, 7.3% less patients had BME on MRI-SIJ according to the Assessment of Spondyloarthritis International Society definition, while 6.6% more patients had ≥5 fatty lesions and/or erosions. At 5 years, 0.7% less patients had ≥5 spinal BME lesions and 0.7% less patients had ≥5 spinal fatty lesions.
Conclusion:
Over 5 years, BME on MRI-SIJ decreased and spinal BME remained similar, but numerically, little progression of structural lesions on MRI of the SIJ and spine was seen.
Keywords: MRI; ankylosing spondylitis; spondyloarthritis.

Un nouvel article scientifique intitulé «What is axial spondyloarthritis? A latent class and transition analysis in the SPACE and DESIR cohorts» a été publié dans le journal Ann Rheum Dis.
Sepriano A, Ramiro S, van der Heijde D, van Gaalen F, Hoonhout P, Molto A, Saraux A, Ramonda R, Dougados M, Landewé R.
OBJECTIVES:
To gain expert-judgement-free insight into the Gestalt of axial spondyloarthritis (axSpA), by investigating its ‘latent constructs’ and to test how well these latent constructs fit the Assessment of SpondyloArthritis international Society (ASAS) classification criteria.
METHODS:
Two independent cohorts of patients with early onset chronic back pain (SPondyloArthritis Caught Early (SPACE)) or inflammatory back pain (IBP) (DEvenir des Spondylarthopathies Indifférenciées Récentes (DESIR)) were analysed. Latent class analysis (LCA) was used to estimate the (unobserved) potential classes underlying axSpA. The best LCA model groups patients into clinically meaningful classes with best fit. Each class was labelled based on most prominent features. Percentage fulfilment of ASAS axSpA, peripheral SpA (pSpA) (ignoring IBP) or both classification criteria was calculated. Five-year data from DESIR were used to perform latent transition analysis (LTA) to examine if patients change classes over time.
RESULTS:
SPACE (n=465) yielded four discernible classes: ‘axial’ with highest likelihood of abnormal imaging and HLA-B27 positivity; ‘IBP+peripheral’ with 100% IBP and dominant peripheral symptoms; ‘at risk’ with positive family history and HLA-B27 and ‘no SpA’ with low likelihood for each SpA feature. LCA in DESIR (n=576) yielded similar classes, except for the ‘no-SpA’. The ASAS axSpA criteria captured almost all (SPACE: 98%; DESIR: 93%) ‘axial’ patients, but the ‘IBP+peripheral’ class was only captured well by combining the axSpA and pSpA criteria (SPACE: 78%; DESIR: 89%). Only 4% of ‘no SpA’ patients fulfilled the axSpA criteria in SPACE. LTA suggested that 5-year transitions across classes were unlikely (11%).
CONCLUSION:
The Gestalt of axSpA comprises three discernible entities, only appropriately captured by combining the ASAS axSpA and pSpA classification criteria. It is questionable whether some patients with ‘axSpA at risk’ will ever develop axSpA.
