The performance of different classification criteria sets for spondyloarthritis in the worldwide ASAS-COMOSPA study
Background: In this study, we sought to compare the performance of spondyloarthritis (SpA) classification criteria sets in an international SpA cohort with patients included from five continents around the world.
Methods: Data from the (ASAS) COMOrbidities in SPondyloArthritis (ASAS-COMOSPA) study were used. ASAS-COMOSPA is a multinational, cross-sectional study with consecutive patients diagnosed with SpA by rheumatologists worldwide. Patients were classified according to the European Spondyloarthropathy Study Group (ESSG), modified European Spondyloarthropathy Study Group (mESSG), Amor, modified Amor, Assessment of SpondyloArthritis international Society (ASAS) axial Spondyloarthritis (axSpA), ASAS peripheral spondyloarthritis (pSpA) and ClASsification criteria for Psoriatic Arthritis (CASPAR) criteria. Overlap between the classification criteria sets was assessed for patients with and without back pain. Furthermore, patients fulfilling different arms of the ASAS axSpA criteria (imaging arm, clinical arm, both arms) were compared on the presence of SpA features.
Results: A total of 3942 patients (5 continents, 26 countries) were included. The mean age was 43.6 years, 65.0% were male, 56.2% were human leucocyte antigen B27-positive and 64.4% had radiographic sacroiliitis (based on modified New York criteria). Of the patients, 85.5% were classified by the ASAS SpA criteria (87.7% ASAS axSpA, 12.3% ASAS pSpA). Fulfilment of the Amor, ESSG and CASPAR criteria was present in 83.3%, 88.4% and 21.6% of patients, respectively. Of the patients with back pain (n = 3227), most were classified by all three of Amor, ESSG and ASAS axSpA criteria (71.4%). Patients fulfilling the imaging arm and the clinical arm of the ASAS axSpA criteria had similar presentations of SpA features. In patients without back pain, overlap between classification criteria sets was seen, although to a lesser extent.
Conclusions: Most patients with a clinical diagnosis of axial SpA in the worldwide ASAS-COMOSPA study fulfil several classification criteria sets, and a substantial overlap between different criteria sets is seen, which suggests a high level of credibility of the criteria. Large inter-regional differences in the fulfilment of classification criteria were not found. Patients fulfilling the clinical arm were remarkably similar to patients fulfilling the imaging arm with respect to the presence of most SpA features
The performance of different classification criteria sets for spondyloarthritis in the worldwide ASAS-COMOSPA study
Increase in Il-31 Serum Levels Is Associated with Reduced Structural Damage in Early Axial Spondyloarthritis
In spondyloarthritis, little is known about the relation between circulating cytokines and patient phenotype. We have quantified serum levels of T helper type 1 cell (Th1), Th2 and Th17 cytokines in patients with recent-onset axial spondyloarthritis (AxSpA) from the DESIR cohort, a prospective, multicenter French cohort consisting of 708 patients with recent-onset inflammatory back pain (duration >3 months but <3 years) suggestive of AxSpA. Serum levels of Th1, Th2, and Th17 cytokines were assessed at baseline in patients from the DESIR cohort fulfilling the ASAS criteria (ASAS+) and were compared with age- and sex-matched healthy controls. At baseline, ASAS+ patients (n = 443) and healthy controls (n = 79) did not differ in levels of most of the Th1, Th2 and Th17 cytokines except for IL-31, and sCD40L, which were significantly higher for ASAS+ patients than controls (p < 0.001 and p = 0.012, respectively). On multivariable analysis of ASAS+ patients, IL-31 level was associated with sCD40L level (p < 0.0001), modified Stoke AS Spine Score (mSASSS) < 1 (p = 0.035). The multivariable analyses showed that IL-31 was an independent factor associated with mSASSS < 1 (p = 0.001) and low bone mineral density (p = 0.01). Increased level of IL-31 might protect against structural damage but is also related to low BMD
Evaluation of the impact of fibromyalgia in disease activity and treatment effect in spondyloarthritis
Bone loss in patients with early inflammatory back pain suggestive of spondyloarthritis: results from the prospective DESIR cohort.
International audienceThe objectives of the study were to assess the 2 year BMD changes and their determinants in patients with early inflammatory back pain suggestive of axial spondyloarthritis (SpA) (DESIR cohort). A total of 265 patients (54% male, mean age 34.4 years) had BMD measurements at baseline and at 2 years. Low BMD was defined as a Z score ≤-2 (at at least one site) and significant bone loss was defined by a decrease in BMD ≥0.03 g/cm(2). Clinical, biological and imaging parameters were assessed over 2 years. Thirty-nine patients (14.7%) had low BMD at baseline; 112 patients (42.3%) had a 2 year significant bone loss. One hundred and eighty-seven (70.6%) used NSAIDs at baseline and 89 (33.6%) received anti-TNF therapy over 2 years. In anti-TNF users, BMD significantly increased at the lumbar spine and did not change at the hip site from baseline. In multivariate analysis, baseline use of NSAIDs [odds ratio (OR) 0.38, P = 0.006] had a protective effect on hip bone loss. In patients without anti-TNF treatments, baseline use of NSAIDs (OR 0.09, P = 0.006) and a 2 year increase in BMI (OR 0.55, P = 0.003) had protective effects on hip bone loss, whereas a 2 year increase in fat mass was associated with hip bone loss (OR 1.18, P = 0.046). Among patients with symptoms suggestive of early axial SpA, 42.3% of patients have significant bone loss over 2 years. Anti-TNF therapy is protective against bone loss and baseline use of NSAIDs has a protective effect on hip bone loss
Preliminary definitions of ‘flare’ in axial spondyloarthritis, based on pain, BASDAI and ASDAS-CRP: an ASAS initiative
International audienceIntroduction Flares may be used as outcomes in axial spondyloarthritis (axSpA) trials or observational studies. The objective was to develop a definition for ‘flare’ (or worsening) in axSpA, based on validated composite indices, to be used in the context of clinical trial design.Methods (1) Systematic literature review of definitions of ‘flare’ in published randomised controlled trials in axSpA. (2) Vignette exercise: 140 scenarios were constructed for a typical patient with axSpA seen at two consecutive visits. Each scenario included a change in one of the following outcomes: pain, Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), BASDAI plus C-reactive protein (CRP) or Ankylosing Spondylitis Disease Activity Score (ASDAS)-CRP. Each Assessment of Spondyloarthritis (ASAS) expert determined if every scenario from a random sample of 46 scenarios was considered a flare (yes/no). Receiver-operating characteristic (ROC) analyses were applied to derive optimal cut-off values. (3) ASAS consensus was reached.Results (1) The literature review yielded 38 studies using some definition of ‘flare’, with 27 different definitions indicating important heterogeneity. The most frequent definitions were based on BASDAI changes or pain changes. (2) 121 ASAS experts completed 4999 flare assessments. The areas under the ROC curves were high (range: 0.88–0.89). Preliminary cut-offs for pain (N=3), BASDAI (N=5) and ASDAS-CRP (N=4) were chosen, with a range of sensitivity 0.60–0.99 and range of specificity 0.40–0.94 against the expert's opinions.Conclusions This data-driven ASAS consensus process has led to 12 preliminary draft definitions of ‘flare’ in axSpA, based on widely used indices. These preliminary definitions will need validation in real patient data
Absence of relationships between depression and anxiety and bone mineral density in patients hospitalized for severe anorexia nervosa
International audienceIntroduction: Low BMD is frequent in anorexia nervosa (AN), depression, and during SSRI treatment but relation between these elements in AN is not established. The aims of this study were to assess the relationships between depression and anxiety, SSRI prescription, and (1) low BMD during inpatient treatment and (2) BMD change 1 year after hospital discharge. Methods: From 2009 to 2011, 212 women with severe AN have been included in the EVHAN study (EValuation of Hospitalisation for AN). Depression, anxiety and obsessive–compulsive symptoms and comorbidity were evaluated using psychometric scales and CIDI-SF. BMD was measured by dual-energy X-ray absorptiometry. Results: According to the CIDI-SF, 56% of participants (n = 70) had a lifetime major depressive disorder, 27.2% (n = 34) had a lifetime obsessive–compulsive disorder, 32.8% (n = 41) had a lifetime generalized anxiety disorder and 25.6% (n = 32) had a lifetime social phobia disorder. Half of the sample (50.7%; n = 72) had a low BMD (Z score ≤ − 2). In multivariate analysis, lifetime lowest BMI was the only determinant significantly associated with low BMD (OR = 0.56, p = 0.0008) during hospitalization. A long duration of AN (OR = 1.40 (0.003–3.92), p = 0.03), the AN-R subtype (OR = 4.95 (1.11–26.82), p = 0.04), an increase of BMI between the admission and 1 year (OR = 1.69 (1.21–2.60), p = 0.005) and a gain of BMD 1 year after the discharge explained BMD change. Conclusion: We did not find any association between depression and anxiety or SSRI treatment and a low BMD or variation of BMD. Level of evidence: Level III, cohort study
Le délai diagnostique de la spondyloarthrite axiale : une étude transversale sur 432 patients
International audienceObjectifs: Le délai diagnostique de la spondyloarthrite axiale (axSpA) est estimé à plus de sept ans mais il semble avoir récemment diminué L’objectif était de quantifier le délai diagnostique chez les patients atteints de axSpA en France et d’en identifier les facteurs associés.Méthodes:Deux études observationnelles transversales ont inclus consécutivement des patients atteints de axSpA (selon les critères ASAS et l’évaluation du rhumatologue). Le délai diagnostique a été défini par l’intervalle de temps entre la date d’apparition des premiers symptômes et celle du diagnostic. Les facteurs potentiellement prédictifs du délai diagnostique analysés par régression linéaire multiple étaient les facteurs démographiques, l’antigène HLA B27, l’année civile du diagnostic, la présentation clinique et la sacro-iliite radiographique ou IRM.Résultats: Au total, 432 patients ont été analysés : l’âge moyen au diagnostic était de 34,2 (écart-type 12,5) ans et la durée moyenne de la maladie au moment de l’évaluation de 11,4 (10,4) ans. Au total, 66,7 % des patients étaient HLA B27 positifs et 70,2 % des sujets présentaient une sacro-iliite radiographique. Le délai diagnostique moyen s’élevait à 4,9 (6,3) ans, avec une valeur médiane de 2,0 ans (écart interquartile, 1-7; étendue : 0-43). En analyse multivariée les facteurs associés de manière indépendante à un délai diagnostique plus long étaient : un âge plus élevé au diagnostic (bêta = 0,13; p<0,001), l’absence d’arthrite périphérique ou de dactylite (bêta =-1,69 p = 0,005) et des douleurs enthésitiques plus fréquentes (bêta = 1,46; p = 0,015).Conclusion: Le délai diagnostique médian était de 2 ans ce qui montre dans la majorité des cas un délai plus court que celui jusqu’alors rapporté. Une présentation clinique plus “typique” de la SpA était associée à un délai diagnostique plus court, tandis que la sacro-iliite radiographique et la positivité du HLA B27 n’étaient pas associés à ce délai
Clinical peripheral enthesitis in the DESIR prospective longitudinal axial spondyloarthritis cohort
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)
