OBJECTIVE:
Scoliosis may impact the mechanical loading and cause secondary changes of the sacroiliac joints and lumbar spine. Our goal was to look how lumbar scoliosis modify the clinical and imaging-study in patients with recent-onset inflammatory back pain (IBP) suggesting axial spondyloarthritis (axSpA).
METHODS:
Baseline weight-bearing lumbar-spine radiographs obtained in the DESIR cohort of patients aged 18-50 years and having IBP for at least 3 months but less than 3 years suggesting axSpA were studied. After training on scoliosis detection based on Cobb’s angle>10° plus Nash-Moe grade≥1, readers blinded to patient data measured spine lumbar scoliosis, sacral horizontal angle, lumbosacral angle and lumbar lordosis on the radiograph of the lumbar and scored sacroiliitis on the radiograph of the pelvis. Baseline MRIs T1 and STIR of the lumbar spine and sacroiliac joints were evaluated for respectively degenerative changes and signs of axSpA.
RESULTS:
Of the 360 patients (50.8% females) 88.7% had lumbar pain and 69.3% met ASAS criteria for axSpA. Mean Cobb’s angle was 3.2°±5.0° and 28 (7.7%) patients had lumbar scoliosis. No statistical differences were observed for radiographic sacroiliitis, MRI sacroiliitis, modified Stoke Ankylosing Spondylitis Spinal Score, Pfirmmann score, high-intensity zone, protrusion, extrusion, MODIC score between patients with and without scoliosis. In both groups, degenerative changes by MRI were rare and predominated at L4-L5 and L5-S1.
CONCLUSION:
In patients with early IBP suggesting axSpA, lumbar scoliosis was not associated with inflammatory or degenerative changes.

Un nouvel article scientifique intitulé «Evaluation of concomitant peripheral arthritis in patients with recent onset axial spondyloarthritis: 5-year results from the DESIR cohort.» a été publié dans le journal Arthritis Res Ther.
López-Medina C, Dougados M, Ruyssen-Witrand A, Moltó A.
BACKGROUND:
(a) To describe the prevalence and incidence of peripheral arthritis during 5 years of follow-up in recent axial spondyloarthritis (axSpA), (b) to evaluate factors associated with their appearance and (c) to assess their impact on treatment, patient-reported outcomes and sick leave after follow-up.
METHODS:
Data from the early axSpA patients from the DESIR cohort (first 5 years of follow-up) were analysed. Prevalence and incidence of peripheral arthritis at each study visit were calculated. A multivariate analysis was performed to evaluate baseline factors associated with the development of the arthritis. The use of drugs, the impact on patient-reported outcomes and days of sick leave were compared in both groups over time.
RESULTS:
Out of the 708 patients included in DESIR, 255 (36.0%) showed at least one episode of arthritis (151 before the inclusion visit and 104 during the follow-up), with an incidence of 3.7 cases per 100 person-years. Patients with peripheral arthritis were more likely (OR, 95%CI) to be aged ≥ 33 years (1.60, 1.12-2.27), non-smokers (1.58, 1.10-2.27) and HLAB27 negative (1.47, 1.04-2.08) and have presented with at least one episode of dactylitis (8.50, 4.96-14.60) and enthesitis (2.00, 1.41-2.84). Patients with peripheral arthritis showed a significant greater use of TNFb, csDMARDs and corticosteroids over follow-up; higher levels on BASDAI (40.46 vs. 34.28) and BASFI (27.89 vs. 22.52); poorer quality of life; and higher number of days of sick leave (17.97 vs. 12.78) over time.
CONCLUSION:
In recent axSpA, 36% of patients reported peripheral arthritis at any time of the disease, being associated with negative HLAB27, non-smokers and with other peripheral manifestations. Patients with arthritis showed a higher burden of disease.

Un nouvel article scientifique intitulé «Impact of gut involvement in patients with high probability of early spondyloarthritis. Data from DESIR cohort.» a été publié dans le journal J Rheumatol.
Wendling D, Guillot X, Prati C, Miceli-Richard C, Molto A, Lories R, Dougados M.
OBJECTIVE:
Inflammatory bowel disease (IBD) is a well-known extra articular feature of spondyloarthritis (SpA).The aims of this study were to evaluate in DESIR cohort factors associated with IBD and incidence over 5 years follow-up.
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 follow-up, with uni and then multivariable analysis.
RESULTS:
At baseline, 708 patients, 35 had IBD : prevalence 4.94% [CI 95% : 3.3 - 6.5]. IBD was associated (multivariable) with history of uveitis, levels of DKK-1 and TNF, 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, BASDAI, and smoking. No association with MRI scores, enthesitis, psoriasis, BMD. 23 incident cases of IBD were recorded: estimated occurrence rate of 0.95/100 [0.57 - 1.35] patient-years. Incidence of IBD is associated (multivariable) with : HLA B27 : OR 0.36 [0.22 - 0.59], fulfillment of modified New York criteria: OR 3.35 [1.85 - 6.08], familial history of IBD : OR 3.31[1.62 - 6.77] .
CONCLUSION:
In early SpA, IBD occurs with an incidence of 1/100 patient-years, and is associated with poor outcome, familial history of IBD, absence of HLA-B27, fulfillment of modified New York criteria.

Un nouvel article scientifique intitulé «Evaluation of the performances of ‘typical’ imaging abnormalities of axial spondyloarthritis: results of the cross-sectional ILOS-DESIR study.» a été publié dans le journal RMD Open.
Molto A, Gossec L, Lefèvre-Colau MM, Foltz V, Beaufort R, Laredo JD, Richette P, Dieude P, Goupille P, Feydy A, Dougados M.
Objective:
To evaluate the prevalence and performance as axial Spondyloarthritis (axSpA) diagnostic feature of radiographic and MRI lesions ‘typical’ of axSpA of the sacroiliac joint (SIJ) and spine in a mechanical chronic back pain (CBP) population and in an axSpA cohort.
Methods:
Cross-sectional multicentre study. Patients: (1) recent onset axSpA (DESIR cohort) and (2) mechanical non-axSpA CBP matched for age and gender (ILOS study). Imaging: radiographs and MR scans were performed identically in both groups. All images were centrally read, blinded for diagnosis and for other imaging findings in the same patient. Statistical analysis: prevalence of lesions ‘typical of axSpA’ were compared in both groups. Sensitivity, specificity and positive likelihood ratios (LR+) of each lesion (and combination of lesions) were calculated.
Results:
A total of 98 patients with CBP were included, and compared with 100 patients with recent onset axSpA. SIJ lesions were consistently more frequent in the axSpA group (35.0% vs 11.8% p<0.001, 35.0% vs 8.4% p<0.001% and 32.0% vs 10.0%. p<0.001 for modified New York criteria, MRI sacroiliitis and ≥3 erosions of the SIJ on MRI, respectively), and performed well (LR+ for ≥3 erosions 3.0 (95% CI 1.6 to 5.8)). Spine lesions were comparable across groups: radiographic lesions were rare, while all MRI lesions were frequent.
Conclusion:
Our study confirms that ‘typical’ lesions can also be observed in patients with non-axSpA CBP but that SIJ lesions by all modalities remain the most valuable for diagnosis, including structural lesions of the SIJ. This suggests the potential interest of adding MRI SIJ structural lesions in the definition of MRI abnormalities for axSpA classification.

Un nouvel article scientifique intitulé «Is a positive family history of spondyloarthritis relevant for diagnosing axial spondyloarthritis once HLA-B27 status is known?» a été publié dans le journal Rheumatology (Oxford).
van Lunteren M, van der Heijde D, Sepriano A, Berg IJ, Dougados M, Gossec L, Jacobsson L, Ramonda R, Rudwaleit M, Sieper J, Landewé R, van Gaalen FA.
OBJECTIVES:
A positive family history (PFH) of spondyloarthritis, in particular a PFH of AS or acute anterior uveitis, is associated with HLA-B27 carriership in chronic back pain patients. As it is unknown, the study aimed to investigate if a PFH contributes to diagnosing axial spondyloarthritis (axSpA) once HLA-B27 status is known.
METHODS:
In axSpA-suspected patients from the Assessment of SpondyloArthritis international Society (ASAS), DEvenir des Spondyloarthropathies Indifférenciéés Récentes (DESIR) and SPondyloArthritis Caught Early (SPACE) cohorts, logistic regression analyses were performed with HLA-B27 status and PFH according to the ASAS definition (ASAS-PFH) as determinants and clinical axSpA diagnosis as outcome at baseline. Analyses were repeated with a PFH of AS or acute anterior uveitis.
RESULTS:
In total, 1818 patients suspected of axSpA were analysed (ASAS n = 594, DESIR n = 647, and SPACE n = 577). In patients from the ASAS, DESIR and SPACE cohorts, respectively 23%, 39% and 38% had an ASAS-PFH, 52%, 58% and 43% were HLA-B27 positive, and 62%, 47% and 54% were diagnosed with axSpA. HLA-B27 was independently associated with an axSpA diagnosis in each cohort but an ASAS-PFH was not [ASAS cohort: HLA-B27 odds ratio (OR): 6.9 (95% CI: 4.7, 10.2), ASAS-PFH OR: 0.9 (95% CI: 0.6, 1.4); DESIR: HLA-B27 OR: 2.1 (95% CI: 1.5, 2.9), ASAS-PFH OR: 1.0 (95% CI 0.7, 1.3); SPACE: HLA-B27 OR: 10.4 (95% CI: 6.9, 15.7), ASAS-PFH OR: 1.0 (95% CI: 0.7, 1.5)]. Similar negative results were found for PFH of AS and acute anterior uveitis.
CONCLUSION:
In three independent cohorts with different ethnical backgrounds, ASAS, DESIR and SPACE, a PFH was not associated independently of HLA-B27 with a diagnosis of axSpA. This indicates that in the vast majority of patients presenting with back pain, a PFH does not contribute to the likelihood of an axSpA diagnosis if HLA-B27 status is known.

Un nouvel article scientifique intitulé «Measuring spinal mobility in early axial spondyloarthritis: does it matter?» a été publié dans le journal Rheumatology (Oxford).
Marques ML, Ramiro S, Goupille P, Dougados M, van Gaalen F, van der Heijde D.
OBJECTIVES:
To investigate the frequency and order of impairment of spinal mobility measures (SMMs) and their cross-sectional and longitudinal usefulness in early axial spondyloarthritis.
METHODS:
SMMs measurements of patients from the DESIR (5-year data) and SPACE (2.6 (1.9) years of follow-up) cohorts were analysed. Cross-sectional (group level) and longitudinal (individual level) analyses were performed comparing SMMs to pre-defined cut-offs derived from healthy individuals. Subgroup analyses were used to study patient and disease characteristics potentially influencing spinal mobility. Reliability was analysed using intraclass correlation coefficients and the smallest detectable change.
RESULTS:
In 328 DESIR and 148 SPACE patients, lateral spinal flexion (LSF) and mSchober were the most impaired SMMs. If both (LSF and mSchober) were measured, 84% (DESIR) and 74% (SPACE) of the patients with impairment in ≥1 SMM would be captured. LSF and Bath AS Metrology Index best discriminated between subgroups of patients (higher impairment in patients ever treated with biologics, with higher disease activity and presence of baseline syndesmophytes): e.g. 31% of LSF impairment in patients with Ankylosing Spondylitis Disease Activity Score (ASDAS) < 2.1 in ≥2/3 visits vs 49% in those with ASDS ≥ 2.1. A high variability in SMMs within the same patient over time was observed, even when restricting the analysis to patients with low disease activity. Reliability of SMMs was ‘fair’ to ‘good’ (inter-reader intraclass correlation coefficients (2, 1): 0.55-0.84; intrareader intraclass correlation coefficients (2, 1): 0.49-0.72). Smallest detectable changes were in general high, e.g. 5.1 cm for LSF.
CONCLUSION:
Cross-sectional use of SMMs, at the group level, is informative in patients with early axial spondyloarthritis. However, the high variation of SMMs over time impairs their use, at the individual patient level.

Un nouvel article scientifique intitulé «Evaluation of the predictive validity of the ASAS axial spondyloarthritis criteria in the DESIR cohort» a été publié dans le journal Clin Exp Rheumatol.
Meghnathi B, Saraux A, Dougados M, Moltó A.
OBJECTIVES:
To evaluate the predictive validity of the Assessment of SpondyloArthritis international Society (ASAS) axial spondyloarthritis (axSpA), Amor, European Spondylarthropathy Study Group (ESSG) and modified New York (mNY) classification criteria.
METHODS:
Patients from the DESIR cohort (inflammatory back pain suggestive of axSpA for >3 months but <3 years duration), followed for up to 5 years. Positive predictive value (PPV) of the set of criteria collected at baseline (ASAS, and its arms, Amor, ESSG and mNY: fulfilled/not fulfilled) were tested against the rheumatologist’s axSpA diagnosis (fulfilled/not fulfilled) after 5 years of follow-up.
RESULTS:
In total, among the 708 patients included in the DESIR cohort at baseline, data on rheumatologist’s diagnosis at 5 years was available in 411 patients; amongst them, 352 (85.6%) had an axSpA diagnosis according to the rheumatologist; 268 patients fulfilled the ASAS axial SpA (axSpA) criteria at baseline and of these, 245 were diagnosed as SpA after 5 years follow-up (PPV: 91%). The PPV of the ASAS « imaging » arm and « clinical » arm was 97% and 82%, respectively. Other criteria also showed similar PPV – Amor (91%), ESSG (90%) and mNY (99%).
CONCLUSIONS:
Positive predictive validity of the ASAS criteria for axSpA (including both arms) at 5 years was excellent; it is worth noting that the performances of the other criteria were also very good in the DESIR cohort.

Un nouvel article scientifique intitulé «Similar alteration for mental and physical aspects in health-related quality of life over 5 to 8 years in 1347 patients with early arthritis and early inflammatory back pain» a été publié dans le journal Arthritis Res Ther.
Puyraimond-Zemmour D1,2,3, Granger B4,5, Molto A6,7, Gaujoux-Viala C8, Guillemin F9, Ruyssen-Witrand A10,11, Dougados M6,7, Fautrel B4,12, Gossec L.
INTRODUCTION:
Health-related quality of life (HRQoL) is a priority for patients. The objectives were to describe the changes in HRQoL over 5-8 years in patients with early arthritis (EA) or early inflammatory back pain (IBP) and to explore factors associated to HRQoL.
PATIENTS AND METHODS:
In 2 prospective observational French cohorts (ESPOIR for EA patients and DESIR for early IBP patients), HRQoL was assessed regularly over 5-8 years, using the SF36 physical and mental composite scores (PCS and MCS, range 0-100). Disease activity was assessed by DAS28-ESR and ASDAS-CRP. Univariate and multivariate linear mixed-effect models and trajectory-based mapping were applied.
RESULTS:
In all, 1347 patients (701 EA and 646 early IBP) were analysed: mean age 48.4 ± 12.2 and 33.9 ± 8.7 years respectively; mean disease duration 3.4 ± 1.7 and 18.2 ± 10.8 months; and 76.3% and 55.0% females. At baseline, in EA, mean PCS and MCS were respectively 40.2 ± 9.1 and 40.4 ± 11.2 and, in early IBP, were respectively 38.5 ± 8.5 and 39.8 ± 10.9. Over follow-up, HRQoL mean levels improved mostly over the first 6 months (p < 0.001). Two trajectories were evidenced in both diseases. The ‘good HRQoL’ trajectory groups, i.e. 54-61% of patients, reached levels of HRQoL close to population norms. DAS28-ESR and ASDAS-CRP over time were related to PCS (range of explained variance 9-43%, p < 0.001 in the mixed models) but not to MCS.
CONCLUSION:
HRQoL was altered similarly for both physical and mental aspects in EA and early IBP. Disease activity only partly explained HRQoL: the drivers of HRQoL should be further explored.

Un nouvel article scientifique intitulé «Association between IL23R and ERAP1 polymorphisms and sacroiliac or spinal MRI inflammation in spondyloarthritis: DESIR cohort data» a été publié dans le journal Arthritis Res Ther.
Ruyssen-Witrand A, Luxembourger C, Cantagrel A, Nigon D, Claudepierre P, Degboe Y, Constantin A.
BACKGROUND:
To investigate the association between 12 single nucleotide polymorphisms (SNPs) located on ERAP1 and IL23R with the presence of inflammation on the sacroiliac joint (SIJ) or spinal magnetic resonance imagery (MRI) in an early onset spondyloarthritis (SpA) cohort.
METHODS:
All the patients included in the DESIR cohort with an axial SpA and available DNA at baseline were enrolled in this study (n = 645 patients) and underwent a clinical examination, CRP assay, SIJ and spinal MRI scans. Six SNPs located on ERAP1 (rs30187, rs27044, rs27434, rs17482078, rs10050860, rs2287987) and six SNPs located on IL23R (rs1004819, rs10489629, rs1343151, rs2201841, rs10889677, rs11209032) were genotyped. Univariable analyses were performed to test the association between the genotypes and SIJ and spinal MRI inflammation, as well as disease activity based on Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), Ankylosing Spondylitis Disease Activity Score-C-Reactive Protein (ASDAS-CRP) and CRP.
RESULTS:
One SNP located on ERAP1 (rs27434) and haplotype CCT of ERAP1 were associated with SIJ inflammation detected by MRI, but these associations were below the Bonferroni corrected threshold of significance. However, one SNP (rs1004819) located on IL23R was associated with SIJ MRI inflammation (rs1004819: TT 42.3%, CT 40.5%, CC 26.5%, p = 0.0005). This locus was also significantly associated with Spondyloarthritis Research Consortium of Canada scores while no association with another inflammatory parameter such as BASDAI, ASDAS-CRP, CRP or Berlin MRI score was identified in this population.
CONCLUSION:
One locus of the IL23R gene was associated with SIJ MRI inflammation and might be a marker of more active disease in recent onset SpA.

Un nouvel article scientifique intitulé «Clinical peripheral enthesitis in the DESIR prospective longitudinal axial spondyloarthritis cohort» a été publié dans le journal Clin Exp Rheumatol.
Nadon V, Moltó A, Etcheto A, Bessette L, Michou L, D’Agostino MA, Claudepierre P, Wendling D, Haraoui P, Dougados M.
OBJECTIVES:
We aimed to describe the prevalence and characteristics of peripheral enthesitis in recent onset axial spondyloarthritis, estimate the incidence of peripheral enthesitis over time, and determine the factors associated with the presence of peripheral enthesitis.
METHODS:
708 patients with recent onset axial spondyloarthritis were enrolled in the DESIR cohort ( prospective multi-centre, longitudinal). Data regarding the patients and spondyloarthritis characteristics at baseline with a specific focus on enthesitis and occurrence of peripheral enthesitis were collected during the five years of follow-up.
RESULTS:
At inclusion, 395 patients (55.8%) reported peripheral enthesitis. The locations were mainly the plantar fascia (53.7%) and the Achilles tendon (38.5%). During the 5-year follow-up period, 109 additional patients developed peripheral enthesitis resulting in an estimated (Kaplan-Meier method) percentage of 71% (95% CI: 68-75). Variables associated with peripheral enthesitis in the univariate analysis were: older age, male gender, absence of HLA B27, MRI sacroiliitis and fulfilled Modified NY criteria, presence of anterior chest wall pain, peripheral arthritis, dactylitis, psoriasis, high BASDAI, BASFI, mean score ASAS-and the use of NSAIDs. Only the history of anterior chest wall pain and of peripheral arthritis were retained in the multivariate analysis (odds ratio (OR)=1.6 [95% confidence interval [1.1-2.3], and OR=2.1 [1.4-3.0], respectively).
CONCLUSIONS:
This study highlights the high prevalence of peripheral enthesitis in recent onset axial spondyloarthritis, and suggests that in combination with peripheral arthritis, enthesitis might have an impact on the burden of the disease.
