Abstract Background Enthesitis-related arthritis (ERA) represents 20% of all juvenile idiopathic arthritis subtype. Among the genetic risk factors for the development of ERA, HLA-B27 has been implicated as a major contributor. The frequency of HLA-B27 varies among population. HLA-B 27 status in ERA may influence the clinical phenotype and prognosis of the disease. The main objective of this study is to determine whether genetic background including HLA B27 and familial history of spondylarthritits (SpA) may influence the clinical features of ERA patients. Methods We conducted a retrospective study including patients with ERA, all fulfilling the International League of Associations for Rheumatology (ILAR) criteria. For all patients, we collected the following data: Age, family history of rheumatic inflammatory diseases, inflammatory bowel diseases (IBD), the presence of HLA-B27 antigen, the inflammatory biomarkers: Erythrocyte sedimentation rate (ESR) C-reactive protein (CRP), the disease activity assessed by morning stiffness, night awakenings, the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and the current treatment. We assessed, as well, the functional impact using the Bath Ankylosing Spondylitis Functional Index (BASFI) the Lequesne index. The population was divided into two groups: a group including patients positive to HLA-B27 antigen and/or with family history of rheumatic inflammatory diseases, psoriasis or inflammatorybowel diseases. The second group was defined as control group with patients negative to HLA-B27 antigen and without any family history of the diseases above. Results We included 40 ERA patients, mean age of onset 12,43 ± 3,003 years (6–16). The majority of them were male (n = 34). Twenty-eight patients had a genetic background. Among them, 7,5% of patients had a positive family history, 42,5% were positive to HLA-B27 antigen and 20% of them met both criteria. As shown in table 1, clinical manifestations were similar between the 2 groups. Enthesitis was more frequent in patients with HLAB27 without a significant difference. Regarding the disease activity, the number of night awakenings and the morning stiffness duration were comparable in the two groups. Six patients had a BASDAI score > 4 with no difference between the two groups. Extra-articular manifestations were present in 15 patients. Among them 14 had a genetic background, reaching the significance threshold with P = 0,013. We counted 8 cases of uveitis, one case of IBD, 5 cases of lung disease and 1 case of cardiac involvement. Inflammatory markers were higher in the group with familial history of SpA and/or positive HLAB27. Indeed, the mean ESR value was 42,73 vs 29.9, P = 0,01. There were no correlations between BASFI score and a positive genetic background (P = 0,283). Only one patient was put on biologics. He has no family history and is negative to HLA-B27 antigen. Conclusion The frequency of HLAB27 was in line with the literature data. The genetic background did not influence the disease activity or the functional impairment in our population. However, a positive correlation was found between a positive familial history of SpA, HLAB27, and the presence of extra-articular manifestations as well as with a higher ESR value.

Abstract Background. Detection of ankylosing spondylitis (AS) in the preclinical stage could help prevent long term morbidity in this patients’ population. The aim of this study was to examine the prevalence of active sacroiliitis in first-degree relatives of AS patients using MRI with clinical and laboratory correlations as these patients may benefit from MRI screening and early treatment.Methods. Seventeen first-degree relatives of AS patients were recruited prospectively. AS screening questionnaires (Ankylosing Spondylitis Disease Activity Score, Bath Ankylosing Spondylitis Disease Activity Index & Visual Analogue Scale), blood tests (C-Reactive Protein, HLA-B27), and an MRI of the SIJs were taken. Two musculoskeletal radiologists interpreted the MRI scans, and two physiotherapists applied four symptom provocation tests (Gaenslen's test, posterior pelvic pain provocation test, Patrick's Faber (PF) test and palpation of the long dorsal SIJ ligament test), and two functional movement tests (active straight leg raise and Stork test). Results. Seven (41%) of the 17 participants demonstrated MRI evidence of active sacroiliitis. Of the 7 participants with active sacroiliitis, two (29%) had no history of recent low back pain (LBP), two (29%) had negative HLA-B27, and one (14%) participant had neither back pain nor positive HLA-B27. The Cohen's Kappa score for the interobserver agreement between the radiologists was 1.00 (p-value <0.0001). Despite fair to strong between therapist agreement for the physical test outcomes (Kappa 0.26 to 1.00), the physical test results per se did not have any predictive association with a positive MRI.Conclusions. MRI detected active sacroiliitis in 41% of first-degree relatives of AS patients. The lack of a history of prior LBP or positive HLA-B27 in active sacroiliitis participants might suggest that MRI screening for this high-risk population is warranted; however, further larger studies are needed to help elucidate its cost-effectiveness and long-term benefits.

Abstract Background Enthesitis related arthritis (ERA) is a subgroup of juvenile idiopathic arthritis. It is characterized by the presence of enthesitis and predominately lower limb arthritis and can affect sacroiliac joint and spine. Recent studies showed that ERA is associated with worse physical status and poorer quality of life (1). The main objective of this study was to compare the aspects of functional status in patients (ERA) and patients with spondyloarthritis (SpA). Methods A retrospective monocentric study was carried out on patients with ERA (ILAR criteria) or SpA (ASAS Criteria). Demographic data and clinical characteristics were obtained from medical records. Disease activity was evaluated by: erythrocyte sedimentation rate (ESR), C-reactive protein rate (CRP) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). Functional impairment was evaluated by Bath Ankylosing Spondylitis Functional Index (BASFI) and Ankylosing Spondylitis Quality of life Questionnaire (ASQoL). Global well-being was assessed by Bath Ankylosing Spondylitis Global Index (BASGI). Population was divided into two groups: group 1 (G1) stands for ERA patients and group 2 (G2) stands for SpA patients. P &lt; 0.05 was considered statistically significant. Results A total of 174 patients (40 ERA and 134 SpA) were enrolled. Mean age at disease onset was 12.4 ± 3 years in G1 and 27.8 ± 8 years in G2. Male to female sex ratio was 5.6 in G1 and 3.7 in G2. Morning stiffness (&gt;60 min) was reported by 37.5% of G1 and 49.3%. G1 patients had longer morning stiffness than G2 (61 [0–90] min vs 30 [0–240] min; P = 0.58). Multiple nocturnal awakenings were reported by 45% of G1 patients and 58.2% of G2 patients. Median BASDAI score was 4.9 [1–44] in G1 and 4.5 in G2 [0–10] (P = 0.48). Median BASGI score was 6 [1.5–9.5] in G1 and 6 [0–10] in G2 (P = 0.58). Median ESR was 35 mm/h [8–90] in G1 and 35 mm/h [2–125] in G2. Median CRP was 18.2 mg/l [1–70] in G1 and 13 mg/l [3–180] in G2. The assessment of functional status revealed that G1 patients had higher BASFI scores than G2 patients (5.2 vs 4.5). The association between G1 and BASFI was statistically significant (P = 0.05). Median ASQoL was 12 [2–17] in G1 and 9 [0–18] in G2. No link was noted between G1 and ASQoL score (P = 0.152). Conclusion Our study showed that ERA was associated with higher BASFI scores in comparison with SpA. Treat-to target strategies are mandatory in order to optimize the functional status of children with ERA.

ObjectiveAltered microbiota composition or dysbiosis is suspected to be implicated in the pathogenesis of chronic inflammatory diseases, such as spondyloarthritis (SpA) and rheumatoid arthritis (RA).Methods16S ribosomal RNA gene sequencing was performed on faecal DNA isolated from stool samples in two consecutive cross-sectional cohorts, each comprising three groups of adult volunteers: SpA, RA and healthy controls (HCs). In the second study, HCs comprised a majority of aged-matched siblings of patients with known HLA-B27 status. Alpha and beta diversities were assessed using QIIME, and comparisons were performed using linear discriminant analysis effect size to examine differences between groups.ResultsIn both cohorts, dysbiosis was evidenced in SpA and RA, as compared with HCs, and was disease specific. A restriction of microbiota biodiversity was detected in both disease groups. The most striking change was a twofold to threefold increased abundance of Ruminococcus gnavus in SpA, as compared with both RA and HCs that was significant in both studies and positively correlated with disease activity in patients having a history of inflammatory bowel disease (IBD). Among HCs, significant difference in microbiota composition were also detected between HLA-B27+ and HLA-B27 negative siblings, suggesting that genetic background may influence gut microbiota composition.ConclusionOur results suggest that distinctive dysbiosis characterise both SpA and RA and evidence a reproducible increase in R. gnavus that appears specific for SpA and a marker of disease activity. This observation is consistent with the known proinflammatory role of this bacteria and its association with IBD. It may provide an explanation for the link that exists between SpA and IBD.

Background:Obesity population are rising rapidly and have become a major health issue. Studies have shown that obesity is a low-grade inflammatory status characterized by increase in proinflammatory cytokines.Objectives:To examine the impact of overweight or obesity on disease activity and treatment responses to biologics in patients with ankylosing spondylitis (AS) in a real-world setting.Methods:Body mass index (BMI) is available in 1013 patients from the Chinese Ankylosing Spondylitis Imaging Cohort (CASPIC). Differences in clinical outcomes (such as BASDAI, ASDAS, BASFI, and ASAS HI) and treatment responses to biologics (ΔBASDAI and ΔASDAS) over 3, 6, 9, and 12 months are assessed between BMI categories (normal weight BMI <24 kg/m2; overweight BMI=24-28 kg/m2; obesity BMI ≥28 kg/m2) using Kruskal-Wallis test. The association between BMI and clinical characteristics and treatment responses to biologics was determined, and multivariate median regression analyses were conducted to adjust for confounders (such as age, gender, smoke, and HLA-B27).Results:Among 1013 patients with AS, overweight accounts for 33%, while obesity for 12.4%. There were significant differences between patients who were obese or overweight and those with a normal weight regarding clinical outcomes (BASDAI: 2.90/2.56 vs 2.21; ASDAS-CRP: 2.20/1.99 vs 1.81; BASFI: 2.13/1.69 vs 1.38; ASAS HI: 6.87/5.29 vs 5.12 and BASMI: 2.35/1.76 vs 1.62; all P<0.05). After adjusting for age, gender, smoke, and HLA-B27, obesity remained associated with higher disease activity (BASDAI: β=0.55, P=0.005; ASDAS-CRP: β=0.40, P<0.001), poorer functional capacity (BASFI: β=0.58, P=0.001), worse health index (ASAS HI: β=1.92, P<0.001) and metrology index (BASMI: β=0.71, P=0.013). For TNFi users, BMI was found to be negatively correlated with changes in disease activity (ΔBASDAI and ΔASDAS) in the multivariate regression model (all P<0.05), and overweight and obese patients showed an unsatisfactory reduction in disease activity during 3-month, 6-month, 9-month, and 12-month follow-up period, compared to normal weight patients (all P<0.05).Conclusion:Overweight or obesity impacts greatly on clinical outcomes and treatment responses to biologics in patients with ankylosing spondylitis, which argues strongly for obesity management to become central to prevention and treatment strategies in patients with AS.References:[1]Maachi M, Pieroni L, Bruckert E, et al.

A 26-year-old male patient presented to our rheumatology clinic with pain, swelling and limitation of movement in his right ankle, and also purpuric skin lesions in the lower extremity pretibial region. He was asked questions, and he said that he had been having chronic low back pain and morning stiffness for the last few years. His physical examination revealed that he had arthritis in his right ankle, purpuric skin lesions in pretibial regions of both legs, and bilateral FABERE/FADIR positivity. The sacroiliac joint imaging and MRI revealed bilateral sacroiliitis findings, and the lateral heel imaging revealed enthesitis. HLA-B27 was positive. Skin biopsy from lower skin lesions was reported to be consistent with leukocytoclastic vasculitis. Based on clinical, laboratory, radiological, and pathological examinations, the patient was diagnosed with ankylosing spondylitis and leukocytoclastic vasculitis. Administration of corticosteroid, salazopyrin, and nonsteroid anti-inflammatory medications was started. Notable clinical and laboratory regression was observed during his checks 3 months later.

ObjectivesTo assess whether family history of rheumatoid arthritis (RA), among the strongest risk factors for developing RA, also carries information on the clinical presentation and treatment response.MethodsThe prospective Swedish Rheumatology register was linked to family history of RA, defined as diagnosed RA in any first-degree relative, ascertained through the Swedish Multi-Generation and Patient registers. Clinical presentation was examined among patients with early RA 2000–2011 (symptom onset <12 months before inclusion, N=6869), and response to methotrexate (MTX) monotherapy in the subset starting this treatment (N=4630). Response to tumour necrosis factor inhibitors (TNFi) was examined among all patients with RA starting a TNFi as the first biological disease-modifying antirheumatic drug 2000–2011 (N=9249). Association of family history with clinical characteristics, drug survival, European League Against Rheumatism (EULAR) response and change in disease activity at 3 and 6 months was estimated using linear and generalised logistic regression models. Correlation in relatives’ response measures was also assessed.ResultsPatients with early RA with family history of RA were more often rheumatoid factor positive, but with no other clinically meaningful differences in their clinical presentation. Family history of RA did not predict response to MTX or TNFi, with the possible exception of no versus good EULAR response to TNFi at 6 months (OR=1.4, 95% CI 1.1 to 1.7). Having a relative who discontinued TNFi within a year increased the odds of doing the same (OR=3.7, 95% CI 1.8 to 7.5), although we found no significant familial correlations in change in disease activity measures.ConclusionsFamily history of RA did not modify the clinical presentation of RA or predict response to standard treatment with MTX or TNFi. Treatment response, particularly drug survival, may itself be familial.

Seventy-four patients with adolescent scoliosis underwent cardiac examination and M-mode echocardiography to detect the presence of mitral valve prolapse (MVP). Twenty-one (28%) had echocardiographic evidence of MVP, whereas 18 had auscultatory findings of a nonejection click or late systolic murmur. A subset of 41 patients had a family history of scoliosis and 37% had MVP. The incidence of MVP increased to 41% when a first degree relative, such as a sibling, parent, or offspring, had scoliosis. Thirty-six patients with scoliosis had additional thoracic hypokyphosis (straight back) and 13 (36%) had MVP. The incidence of MVP was 48% when the scoliosis and hypokyphosis were hereditary and increased to 53% when a familial history of skeletal abnormality was present. This study indicates a high incidence of MVP in patients with scoliosis and hypokyphosis, especially when the skeletal abnormality is familial. It suggests that the cardiac and skeletal systems may be affected by a generalized soft-tissue defect.

Abstract 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.

Objective.To compare baseline disease activity and treatment effectiveness in biologic-naive patients with nonradiographic axial spondyloarthritis (nr-axSpA) and ankylosing spondylitis (AS) who initiate tumor necrosis factor inhibitor (TNFi) treatment and to study the role of potential confounders (e.g., HLA-B27 status).Methods.Observational cohort study based on prospectively registered data in the nationwide DANBIO registry. We used Kaplan-Meier plots, Cox, and logistic regression analyses to study the effect of diagnosis (nr-axSpA vs AS) and potential confounders (sex/age/start yr/HLA-B27/disease duration/TNFi-type/smoking/baseline disease activity) on TNFi adherence and response [e.g., Bath Ankylosing Spondylitis Activity Index (BASDAI) 50%/20 mm].Results.The study included 1250 TNFi-naive patients with axSpA (29% nr-axSpA, 50% AS, 21% lacked radiographs of sacroiliac joints). Patients with nr-axSpA were more frequently women (50%/27%) and HLA-B27–negative (85/338 = 25%), compared to AS (81/476 = 17%; p < 0.01). At TNFi start patients with nr-axSpA had higher visual analog scale scores [median (quartiles)] for pain: 72 mm (55–84)/65 mm (48–77); global: 76 mm (62–88)/68 mm (50–80); fatigue: 74 mm (55–85)/67 mm (50–80); and BASDAI: 64 (54–77)/59 (46–71); all p < 0.01. However, patients with nr-axSpA had lower C-reactive protein: 7 mg/l (3–17)/11 mg/l (5–22); and BAS Metrology Index: 20 (10–40)/40 (20–50); all p < 0.01. Median (95% CI) treatment adherence was poorer in nr-axSpA than in AS: 1.59 years (1.15–2.02) versus 3.67 years (2.86–4.49), p < 0.0001; but only in univariate and not confounder-adjusted analyses (p > 0.05). Response rates were similar in AS and nr-axSpA (p > 0.05). HLA-B27 negativity was associated with poorer treatment adherence [HLA-B27 negative/positive, nr-axSpA: HR 1.74 (1.29–2.36), AS: HR 2.04 (1.53–2.71), both p < 0.0001]; and lower response rates (nr-axSpA: 18/61 = 30% vs 93/168 = 55%; AS: 17/59 = 29% vs 157/291 = 54%, both p < 0.05).Conclusion.In this nationwide cohort, patients with nr-axSpA had higher subjective disease activity at start of first TNFi treatment, but similar outcomes to patients with AS after confounder adjustment. HLA-B27 positivity was associated with better outcomes irrespective of axSpA subdiagnosis.
