RESUMEN
OBJECTIVE: To explore the registration of enthesitis among biologic-naïve patients with psoriatic arthritis (PsA) initiating tumour necrosis factor inhibitor (TNFi) treatment across 12 European registries, compare the disease burden and patient-reported outcomes (PROs) between patients with and without enthesitis, and assess the enthesitis treatment response. METHOD: Demographics, clinical characteristics, and PROs at first TNFi (TNFi-1) initiation (baseline) were assessed in patients with PsA, diagnosed by a rheumatologist, with versus without assessment of entheses and between those with versus without enthesitis. Enthesitis scores and resolution frequency were identified at follow-up. RESULTS: Of 10 547 patients in the European Spondyloarthritis (EuroSpA) Research Collaboration Network initiating TNFi, 1357 underwent evaluation for enthesitis. Eight registries included a validated scoring system for enthesitis. At baseline, 874 patients underwent entheses assessment [Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) 485 patients, Spondyloarthritis Research Consortium of Canada (SPARCC) 389 patients]. Enthesitis was detected by MASES in 170/485 (35%, mean score ± sd 3.1 ± 2.4) and by SPARCC in 236/389 (61%, 4 ± 3.4). Achilles enthesitis was most frequent, by both MASES (unilateral/bilateral 28%/9%) and SPARCC (48%/18%). MASES/SPARCC baseline and follow-up scores for TNFi-1 were available for 100/105 patients. Of these, 63 patients (63%) (MASES) and 46 (43.8%) (SPARCC) achieved resolution of enthesitis. The site-specific enthesitis resolution was overall lower at SPARCC sites (peripheral; 63-80%) than at MASES sites (mainly axial; 82-100%) following TNFi-1. Disease activity and PROs were worse in patients with versus without enthesitis. CONCLUSION: Entheseal assessments are only registered in a minority of patients with PsA in routine care. When assessed, enthesitis was common, and a substantial proportion demonstrated resolution following treatment with TNFi-1.

OBJECTIVE: 14-3-3η is a proinflammatory mediator critical to joint destruction in rheumatoid arthritis (RA). We aimed to evaluate serum 14-3-3η for predicting disease activity and radiographic progression in patients with early RA in the double-blinded, randomized OPERA trial. METHOD: 180 patients with early RA were randomized to receive methotrexate (MTX) + adalimumab or MTX + placebo in combination with glucocorticoid injections into swollen joints. Disease activity was measured using the 28-joint Disease Activity Score-C-reactive protein (DAS28-CRP). Clinical remission was defined as DAS28-CRP < 2.6. X-rays of hands and feet were evaluated by the Total Sharp van der Heijde score (TSS). Radiographic progression was defined as exceeding the smallest detectable change (1.8 TSS-units). Serum 14-3-3η was determined by enzyme-linked immunosorbent assay. Multivariate logistic regression models were used to identify predictors of DAS28-CRP remission at 6 months and radiographic progression at 12 months. RESULTS: Baseline 14-3-3η was a borderline significant independent predictor of radiographic progression at 12 months (odds radio = 1.02, 95% confidence interval 1.00-1.03, p = 0.05). In anti-cyclic citrullinated peptide antibody (ACPA)-negative patients, a moderate/high baseline 14-3-3η concentration increased the risk of radiographic progression at 12 months [4/51 (8%) vs 3/9 (33%), χ2 = 4.823, p = 0.028]. No value of 14-3-3η for predicting achievement of clinical remission was found. CONCLUSION: Serum 14-3-3η was a borderline significant predictor of radiographic progression, particularly in ACPA-negative patients, but not of predicting achievement of clinical remission. Optimal cut-off levels of 14-3-3η for predicting radiographic progression in RA need further clarification.

OBJECTIVE: Smoking and periodontitis are risk factors for developing rheumatoid arthritis (RA), suggesting a break of tolerance on mucosal surfaces. Immunoglobulin A (IgA) antibodies are part of the mucosal immune system. The dominant autoantibodies in RA are anti-cyclic citrullinated protein antibodies (ACPAs), and IgG and IgA subclasses exist simultaneously. This study aimed to investigate the association of ACPA IgA subtypes with disease activity and long-term radiographic outcomes in RA, compared with ACPA IgG. METHOD: Total ACPA IgG, IgA, IgA1, and IgA2 were quantified in serum from patients with early RA (n = 97). Patient characteristics, IgM rheumatoid factor (IgM-RF) status, clinical and biochemical disease activity scores, and radiographic status evaluated by total Sharp score (TSS), were assessed at baseline and after 2 and 11 years of treatment. RESULTS: All patients with ACPA IgA also had ACPA IgG. ACPA IgA positivity was associated with IgM-RF and male gender. Both ACPA IgA and IgG levels at baseline were weakly associated with disease activity markers. Baseline ACPA IgA and IgG did not show a linear correlation with radiographic status after 10 years, but could predict radiographic progression (ΔTSS ≥ 5 from 0 to 11 years), with positive likelihood ratios of 3.7 and 4.0, respectively. CONCLUSION: ACPA IgA and IgG were weakly associated with disease activity in early RA. RA patients with a ΔTSS ≥ 5 after 11 years of treatment had higher ACPA IgG and ACPA IgA levels at baseline; however, none of the ACPA subtypes was superior in predicting long-term radiographic progression.

OBJECTIVE: Galectin-3 (Gal-3) has been suggested as a proinflammatory mediator in rheumatoid arthritis (RA). We aimed to study clinical and pathogenic aspects of Gal-3 in RA. METHOD: Plasma samples from healthy controls (n = 48) and patients with newly diagnosed, early RA were assayed for soluble Gal-3. In patients with chronic RA (n = 18), Gal-3 was measured in both plasma and synovial fluid. Synovial fluid mononuclear cells were used to purify fibroblast-like synoviocytes (FLSs) and osteoclasts. Monocultures of FLSs and autologous co-cultures of FLSs and peripheral blood mononuclear cells were established and co-incubated with a Gal-3 inhibitor. RESULTS: Patients with early and chronic RA had persistently increased plasma levels of Gal-3 compared with controls. However, changes in plasma Gal-3 at the level of individuals were associated with long-term disease activity. In seropositive early RA patients, all patients with decreasing plasma Gal-3 from 0 to 3 months had low disease activity after 2 years (p < 0.05). Gal-3 levels in synovial fluid were markedly elevated. In vitro, co-incubation with a Gal-3 inhibitor (GB1107, 10 µM) led to a significant reduction in both interleukin-1ß and tumour necrosis factor-α secretion from FLS monocultures (both p < 0.05) and decreased monocyte-derived osteoclastogenesis compared with controls (both p < 0.05). CONCLUSIONS: Our findings underscore the role of Gal-3 regarding disease activity and tissue destruction in RA. An initial decrease in plasma Gal-3 levels predicted decreased long-term disease activity. Correspondingly, a Gal-3 inhibitor decreased the activity of inflammatory FLSs and osteoclastogenesis in patients with RA.

OBJECTIVES: To compare the effect of treat-to-target-based escalations in conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and biologics on clinical disease activity and magnetic resonance imaging (MRI) inflammation in a rheumatoid arthritis (RA) cohort in clinical remission. METHOD: One-hundred patients with established RA, Disease Activity Score based on 28-joint count-C-reactive protein (DAS28-CRP) < 3.2, and no swollen joints (hereafter referred to as 'in clinical remission') who received csDMARDs underwent clinical evaluation and MRI of the wrist and second to fifth metacarpophalangeal joints every 4 months. They followed a 2 year MRI treatment strategy targeting DAS28-CRP ≤ 3.2, no swollen joints, and absence of MRI osteitis, with predefined algorithmic treatment escalation: first: increase in csDMARDs; second: adding a biologic; third: switch biologic. MRI osteitis and Health Assessment Questionnaire (HAQ) (co-primary outcomes) and MRI combined inflammation and Simplified Disease Activity Index (SDAI) (key secondary outcomes) were assessed 4 months after treatment change and expressed as estimates of group differences. Statistical analyses were based on the intention-to-treat population analysed using repeated-measures mixed models. RESULTS: Escalation to first biologic compared to csDMARD escalation more effectively reduced MRI osteitis (difference between least squares means 1.8, 95% confidence interval 1.0-2.6), HAQ score (0.08, 0.03-0.1), MRI combined inflammation (2.5, 0.9-4.1), and SDAI scores (2.7, 1.9-3.5). CONCLUSIONS: Treat-to-target-based treatment escalations to biologics compared to escalation in csDMARDs more effectively improved MRI inflammation, physical function, and clinical disease activity in patients with established RA in clinical remission. Treatment escalation in RA patients in clinical remission reduces clinical and MRI-assessed disease activity. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT01656278.

Objective: The aim was to explore dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) as an early marker of therapeutic response in patients with rheumatoid arthritis (RA) starting treatment with certolizumab pegol (CZP).Method: In 40 RA patients initiating CZP (27 patients) or 2 weeks of placebo (PCB) followed by CZP (13 patients), DCE-MRI of the metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints was performed at weeks 0, 1, 2, 4, 8, and 16. Using semi-automated software, three methods for drawing volume regions of interest (ROIs) in MCP2-5 and PIP2-5 were applied: 'Standard' (slices: all; joints: MCP2-5 together and PIP2-5 together), 'Detailed' (slices: slices with high-quality visualization; joints: as Standard), and 'Single-joint' (slices: as Detailed; joints: each joint separately). The number of enhancing voxels (Nvoxel), initial rate of enhancement (IRE), and maximum enhancement (ME) were extracted and analysed for each method.Results: Nvoxel in MCP2-5, and IRE and ME in PIP2-5 decreased statistically significantly (Wilcoxon rank-sum test, p < 0.02-0.03) after 16 weeks of treatment for the Standard method. Nvoxel and ME decreased significantly more in the CZP group than in the PCB group after 1 week of treatment, but not at later time-points. There were no significant changes for DCE-MRI parameters for the Detailed and Single-joint methods.Conclusions: Certain DCE-MRI parameters detected decreased inflammation during CZP treatment in RA patients. Using specific criteria for ROIs, as in the Detailed and Single-joint methods, decreased the statistical power and could not show any changes over time.

Objectives: The Spondyloarthritis Research Consortium of Canada (SPARCC) sacroiliac joint (SIJ) scoring system assesses six or five (6/5) semicoronal magnetic resonance imaging (MRI) slices for inflammation/structural lesions in patients with axial spondyloarthritis (axSpA). However, the cartilaginous SIJ compartment may be visible in a few additional slices. The objective was to investigate interreader reliability, sensitivity to change, and classification of MRI scans as positive or negative for various lesion types using an 'all slices' approach versus standard SPARCC scoring of 6/5 slices.Method: Fifty-three axSpA patients were treated with the tumour necrosis factor inhibitor golimumab and followed with serial MRI scans at weeks 0, 4, 16, and 52. The most anterior and posterior slices covering the cartilaginous compartment and the transitional slice were identified. Scores for inflammation, fat metaplasia, erosion, backfill, and ankylosis in the cartilaginous SIJ compartment were calculated for the 'all slices' approach and the 6/5 slices standard.Results: By the 'all slices' approach, three readers scored mean 7.2, 7.7, and 7.0 slices per MRI scan. Baseline and change scores for the various lesion types closely correlated between the two approaches (Pearson's rho ≥ 0.95). Inflammation score was median 13 (interquartile range 6-21, range 0-49) for 6/5 slices versus 14 (interquartile range 6-23, range 0-69) for all slices at baseline. Interreader reliability, sensitivity to change, and classification of MRI scans as positive or negative for various lesion types were similar.Conclusion: The standardized 6/5 slices approach showed no relevant differences from the 'all slices' approach and, therefore, is equally suited for monitoring purposes.

OBJECTIVE: To investigate whether axial spondyloarthritis (axSpA) patients with extremely poor patient-reported outcomes (PROs) at start of first tumour necrosis factor inhibitor (TNFi) treatment have poorer treatment response and shorter treatment retention than other patients. METHOD: This observational cohort study was based on the nationwide DANBIO registry. Patients with axSpA who started first TNFi during 2011-2016 were stratified according to baseline Bath Ankylosing Spondylitis Disease Activity Index (BASDAI ≥ 0.0 to ≤ 4.0, > 4.0 to ≤ 5.0, > 5.0 to ≤ 6.0, > 6.0 to ≤ 7.0, > 7.0 to ≤ 8.0, > 8.0 to ≤ 9.0, and > 9.0 to ≤ 10.0). An extremely poor BASDAI was defined as BASDAI > 9.0 to ≤ 10.0. Treatment responses after 6 months [≥ 50% improvement from baseline BASDAI (BASDAI50), ≥ 40% improvement in Assessment of SpondyloArthritis international Society (ASAS40) response, and ASAS partial remission] in patients with extremely poor PROs were compared with other patients by chi-squared tests, and retention rates by log-rank tests. Similar analyses were done for Bath Ankylosing Spondylitis Functional Index (BASFI), pain score, and patient global score. RESULTS: The study included 1396 patients (median age 39 years, 60% men). Patients with extremely poor baseline BASDAI [63 patients (5%)] were more often women, ever smokers, and human leucocyte antigen-B27 negative, and had higher body mass index. Response rates were poorer in patients with extremely poor BASDAI vs remaining patients (BASDAI50 19% and 41%, respectively, p < 0.001; ASAS40 16% and 35%, p = 0.002; ASAS partial remission 6% and 22%, p < 0.001). Patients with extremely poor BASDAI had lower 1 year treatment retention (51% and 68%, p < 0.001). Largely similar results were found for patients with extremely poor BASFI, pain score, and patient global score. CONCLUSION: Patients who reported an unusually large symptom burden at baseline had poor response rates and low retention rate. In such cases, competing causes of pain should carefully be taken into account when considering treatment with TNFi.

OBJECTIVE: To investigate temporal changes in structural progression assessed by serial conventional radiography and magnetic resonance imaging (MRI) of the sacroiliac joints (SIJs) and spine in patients with ankylosing spondylitis (AS) treated with tumour necrosis factor (TNF) inhibitor for 5 years. METHOD: Forty-two patients were included and 33 patients were followed for 5 years in a prospective investigator-initiated study. Conventional radiographs were required four times and MRI seven times. The modified Stoke Ankylosing Spondylitis Spinal Score (mSASSS); Spondyloarthritis Research Consortium of Canada (SPARCC) MRI SIJ and Spine Inflammation, and SPARCC MRI SIJ Structural Score (SSS) for Fat, Erosion, Backfill, and Ankylosis; and the Canada-Denmark MRI scores for Spine Inflammation, Fat, Erosion, and New Bone Formation (NBF) were applied. RESULTS: Compared with baseline, MRI Inflammation had decreased significantly at week 22 (spine)/week 46 (SIJ) and thereafter. MRI SIJ Fat (from week 22), SIJ Ankylosis, Spine NBF, and mSASSS had increased significantly at week 46 and thereafter. SIJ Erosion had decreased from year 2. The annual progression rate in mSASSS was significantly higher during weeks 0-46 compared to week 46 to year 3. In multivariate regression analyses, baseline SIJ Inflammation and Backfill were independent predictors of 5 year progression in SIJ Ankylosis. Spine Erosion predicted progression in Spine NBF. Longitudinally, Ankylosing Spondylitis Disease Activity Score, Bath Ankylosing Spondylitis Disease Activity Index, MRI Spine Inflammation, Fat, and Erosion scores were significantly associated with mSASSS. SIJ Inflammation, Fat, Erosion, and Backfill scores were longitudinally associated with SIJ Ankylosis. Structural progression was not associated with body mass index, smoking, or Assessment of SpondyloArthritis international Society Non-Steroidal Anti-Inflammatory Drug Index. CONCLUSION: In a 5 year follow-up study of patients with AS treated with TNF inhibitor, structural progression decreased over time.

OBJECTIVE: To investigate the clinical and radiographic status, and to identify baseline predictors of functional status and erosive progression at 11 years' follow-up of early rheumatoid arthritis (RA) patients. METHODS: Patients enrolled in the Danish investigator-initiated randomized controlled CIMESTRA trial, which investigated a 2 year treat-to-target intervention with methotrexate and intra-articular glucocorticoids with or without cyclosporine, were followed up. The 28-joint Disease Activity Score (DAS28), Health Assessment Questionnaire (HAQ) score, and total Sharp van der Heijde score (TSS) were assessed at baseline and 11 years. Baseline magnetic resonance imaging (MRI) of unilateral wrists was scored (OMERACT RAMRIS). Multivariable linear regression analyses of baseline variables [TSS, HAQ, DAS28, age, anti-cyclic citrullinated peptide (anti-CCP) status, gender, MRI erosion score, MRI synovitis score, MRI bone marrow oedema score] were performed in 96 patients with HAQ11yrs and ∆TSS0-11yrs as dependent variables. Since outcomes were similar in the two treatment arms, data were pooled. RESULTS: In total, 120 of 160 patients completed 11 years' follow-up. They were 63 (55-72) years old, 68% were in DAS28 remission (≤ 2.4), HAQ11yrs was 0.25 (0-0.75), mean ∆TSS0-11yrs was 0.96 ± 1.52 units/year; 53%, 20%, and 27% received conventional treatment, biologics, and no treatment, respectively; and 34% had not progressed radiographically since baseline. Increased DAS28 (p = 0.02) and anti-CCP (p = 0.03) predicted HAQ11yrs, whereas anti-CCP (p = 0.03) and MRI bone marrow oedema (p = 0.01) predicted ∆TSS0-11yrs in multivariable analyses. CONCLUSIONS: Early and strict synovitis suppression with methotrexate and intra-articular glucocorticoids led to persistently high remission rates and limited erosive progression at 11 years. In this well-treated cohort, baseline anti-CCP status, DAS28, and MRI bone marrow oedema predicted functional status and/or erosive progression.

OBJECTIVES: Measurement of serum biomarkers at disease onset may improve prediction of disease course in patients with early rheumatoid arthritis (RA). We evaluated the multi-biomarker disease activity (MBDA) score and early changes in MBDA score for prediction of 28-joint Disease Activity Score based on C-reactive protein (DAS28-CRP) remission and radiographic progression in the double-blinded OPERA trial. METHOD: Treatment-naïve RA patients (N = 180) with moderate or high DAS28 were randomized to methotrexate (MTX) + adalimumab (n = 89) or MTX + placebo (n = 91) in combination with glucocorticoid injection into swollen joints. X-rays of hands and feet were evaluated at months 0 and 12 (n = 164) by the total Sharp van der Heijde score (TSS). The smallest detectable change (1.8 TSS units) defined radiographic progression (∆TSS ≥ 2). Clinical remission (DAS28-CRP < 2.6) was assessed at baseline and 6 months. MBDA score was determined at 0 and 3 months and tested in a multivariable logistic regression model for predicting DAS28 remission at 6 months and radiographic progression at 1 year. RESULTS: Baseline MBDA score was independently associated with radiographic progression at 1 year [odds ratio (OR) = 1.03/unit, 95% confidence interval (CI) = 1.01-1.06], and changes in MBDA score from baseline to 3 months with clinical remission at 6 months [OR = 0.98/unit, 95% CI 0.96-1.00). In anti-cyclic citrullinated peptide antibody (anti-CCP)-positive patients, 35 of 89 with high MBDA score (> 44) showed radiographic progression (PPV = 39%), compared with 0 of 15 patients (NPV = 100%) with low/moderate MBDA score (≤ 44) (p = 0.003). CONCLUSION: Early changes in MBDA score were associated with clinical remission based on DAS28-CRP at 6 months. In anti-CCP-positive patients, a non-high baseline MBDA score (≤ 44) had a clinical value by predicting very low risk of radiographic progression at 12 months.

BACKGROUND: There are scarce data in Scandinavia about treatment satisfaction among patients with psoriasis (PsO) and/or psoriatic arthritis (PsA). The number of patients receiving systemic treatment is unknown. OBJECTIVE: To describe patients' experience of treatments for PsO/PsA in Sweden, Denmark and Norway, addressing communication with physicians, satisfaction with treatment and concerns regarding treatment options. METHODS: The NORdic PAtient survey of Psoriasis and Psoriatic arthritis (NORPAPP) asked 22 050 adults (randomly selected from the YouGov panels in Sweden, Denmark and Norway) whether they had PsO/PsA. A total of 1264 individuals who reported physician-diagnosed PsO/PsA were invited to participate in the full survey; 96.6% responded positively. RESULTS: Systemic treatment use was reported by 14.6% (biologic: 8.1%) of respondents with PsO only and by 58.5% (biologic: 31.8%) of respondents with PsA. Biologic treatments were more frequently reported by respondents considering their disease severe (26.8% vs 6.7% non-severe) and those who were members of patient organizations (40.7% vs 6.9% non-members). Discussing systemic treatments with their physician was reported significantly more frequently by respondents with PsA, those perceiving their disease as severe (although 35.2% had never discussed systemic treatment with their physician) and those reporting being a member of a patient organization (P < 0.05). Many respondents reported health risk concerns and dissatisfaction with their treatment. Of special interest was that respondents aged 45-75 years reported less experience with biologics (8.1%) than those aged 18-44 years (21.5%). The older respondents also reported more uncertainty regarding long-term health risks related to systemic treatments (most [66.7-72.9%] responded 'do not know' when asked about the risk of systemic options). CONCLUSION: It appears likely that substantial numbers of Scandinavians suffering from severe PsO/PsA are not receiving optimal treatment from a patient perspective, particularly older patients. Also, one-third of respondents with severe symptoms had never discussed systemic treatment with a physician.

OBJECTIVE: To investigate serum interleukin-6 (IL-6), serum chitinase-3-like protein-1 (YKL-40), and plasma vascular endothelial growth factor (VEGF) as measures of disease activity and predictors of clinical remission and radiographic progression in two early rheumatoid arthritis (RA) randomized controlled trials (RCTs). METHOD: Treatment-naïve patients with early RA (< 6 months' duration) and active disease, participating in two investigator-initiated RCTs, were treated according to a predefined treat-to-target algorithm aiming at inflammatory control, using methotrexate (MTX) + cyclosporine versus MTX + placebo (CIMESTRA study, n = 150, 5 year follow-up) or MTX + adalimumab versus MTX + placebo (OPERA study, n = 180, 2 year follow-up). The 28-joint Disease Activity Score (DAS28) and conventional radiography [bilateral hands and feet at baseline, 2 years and 5 years (only CIMESTRA)] were obtained at baseline and during follow-up. Serum IL-6, serum YKL-40, and plasma VEGF were measured in baseline blood samples and during follow-up. Hypotheses regarding the biomarkers' relation with DAS28 and ability to predict clinical remission (DAS28 < 2.6) and radiographic progression (change in total Sharp van der Heijde score ≥ 2) were generated in CIMESTRA and validated in OPERA, by Spearman's correlation and logistic regression analyses. RESULTS: Baseline IL-6, YKL-40, and VEGF correlated significantly with DAS28 in CIMESTRA (r = 0.50, r = 0.36, r = 0.36, respectively, all p < 0.01) and these results were confirmed in OPERA patients (r = 0.52, p < 0.01; r = 0.18, p = 0.01; r = 0.23, p = 0.002, respectively). None of the biomarkers (absolute values or change) was predictive of clinical remission or radiographic progression at 2 or 5 years in either study. CONCLUSION: Serum IL-6, serum YKL-40, and plasma VEGF were significantly correlated with DAS28 at baseline, but did not have consistent predictive value for clinical remission or radiographic progression in two early RA RCTs.

PURPOSE: The aim of this study was to develop and gather validity evidence for a standardised test of competence in Focused Assessment with Sonography for Trauma (FAST) and to define the appropriate cut-off point in simulation-based learning of the FAST protocol. METHODS: A 20-item simulation-based test for assessing competence in FAST was created. The test was administered to thirteen novices and twelve radiologists experienced in abdominal ultrasound diagnostics. The Contrasting Groups' method was used to establish a credible passing score. RESULTS: The internal consistency was high (Cronbach's α = 0.90) and the test had good discriminatory ability (P < .001). The mean score was 16.9 (95% CI: 15.5-18.3) in the experienced group and 8.0 (95% CI: 5.8-10.2) in the novice group, corresponding to 85% and 40% of the total score, respectively. A pass/fail standard of 14 points was established using the Contrasting Groups' method. CONCLUSIONS: The FAST simulation-based test provided valid assessment of competence in FAST. The FAST test could be used to guide training and ensure basic competence of physicians using FAST.
RESUMEN
Galectin-3 has been suggested as a pro-inflammatory mediator in animal arthritis and rheumatoid arthritis (RA). We aimed to study the serum level of galectin-3 in patients with newly diagnosed RA and associations with disease profile, Magnetic resonance imaging (MRI) findings and seromarkers of synovial matrix inflammation. One hundred and sixty DMARD naïve patients newly diagnosed with RA were included (CIMESTRA study). Clinical, serological and imaging data were recorded before treatment and at 6 weeks, 3 and 12 months. Galectin-3 and hyaluronan (HYA) were measured by ELISA (R&D and Corgenix, USA), and the N-terminal propeptide of type III collagen (PIIINP) by radioimmunoassay (Orion Diagnostica, Finland). One hundred and nineteen, 87 and 60 blood donors served as controls for galectin-3, HYA and PIIINP, respectively. Baseline galectin-3 was significantly elevated in anti-CCP positive (4.2 µg/l IQR [3.6;6.1]) patients as compared with anti-CCP negatives (4.0 µg/l [2.6;4.9], P = 0.05) and controls (3.8 µg/l [3.0;4.8], P < 0.01). During treatment, galectin-3 remained elevated, but increased transiently with peak values at 6 weeks. Galectin-3 correlated with baseline smoking, anti-CCP, and with MRI erosion score after 1 year of follow-up. HYA and PIIINP were elevated (P < 0.001) irrespective of anti-CCP status and correlated positively with synovitis assessed clinically and by MRI. HYA and PIIINP did not correlate with galectin-3. These observations indicate that HYA and PIIINP mainly reflect expansive synovitis proliferation while galectin-3 is more closely linked to autoimmunity, smoking and joint destructive processes.

OBJECTIVES: To investigate the multi-biomarker disease activity (MBDA) score by comparison with imaging findings in an investigator-initiated rheumatoid arthritis (RA) trial (HURRAH trial, NCT00696059). METHOD: Fifty-two patients with established RA initiated adalimumab treatment and had magnetic resonance imaging (MRI), ultrasonography (US), computed tomography (CT), and radiography performed at weeks 0, 26, and 52. Serum samples were analysed using MBDA score assays and associations between clinical measures, MBDA score, and imaging findings were investigated. RESULTS: The MBDA score correlated significantly with MRI synovitis (rho = 0.65, p < 0.001), MRI bone marrow oedema (rho = 0.36, p = 0.044), and US power Doppler (PD) score at week 26 (rho = 0.35, p = 0.039) but not at week 0 or week 52. In the 15 patients who had achieved a Disease Activity Score based on C-reactive protein (DAS28-CRP) < 2.6 at week 26, MRI and/or US detected subclinical inflammation and 13 (87%) had a moderate/high MBDA score. For the cohort with available data, none of the four patients in MBDA remission (score ≤ 25) at week 26 had progression of imaging damage from baseline to week 52 whereas progression was observed in three out of nine (33%) and seven out of 21 (33%) patients with moderate (30-44) and high (> 44) MBDA scores, respectively. CONCLUSIONS: In this cohort, the MBDA score correlated poorly with MRI/US inflammation. However, the MBDA score and MRI/US were generally concordant in showing signs of inflammation in most patients in clinical remission during anti-tumour necrosis factor (anti-TNF) therapy. MBDA scores were elevated in all patients with structural damage progression.

OBJECTIVES: To investigate whether antibody response patterns against Klebsiella pneumoniae capsular serotypes can discriminate patients with axial spondyloarthritis (axSpA) from patients with non-specific low back pain (LBP). METHOD: Immunoglobulin (Ig)G and IgA antibodies against K. pneumoniae capsular serotypes K2, K26, K36, and K50 were measured, and antibody seropositivity compared between groups and analysed for patient correlation in five different groups: (a) 96 patients fulfilling the Assessment of SpondyloArthritis International Society (ASAS) classification criteria for axSpA; (b) 38 patients with either a positive magnetic resonance imaging (MRI) scan as defined by ASAS or a positive human leucocyte antigen (HLA)-B27 status plus one clinical SpA feature, characterized as 'non-axSpA'; (c) 82 non-specific LBP patients; (d) 40 healthy blood donors and (e) 43 patients with diagnosed ankylosing spondylitis (AS) served as the negative and positive control groups. RESULTS: There was no difference in IgG and IgA seropositivity against all serotypes between the axSpA, non-axSpA, and LBP groups. No significant correlations were found between anti-Klebsiella antibodies and age, gender, HLA-B27, or high-sensitivity C-reactive protein (hsCRP). IgG seropositivity against K50 was more frequent in AS (25.6%) than in axSpA (13.5%, p < 0.05). axSpA patients with radiographic sacroiliitis and AS controls concordantly had the highest frequency of seropositivity for ≥ 2 serotypes (21%). CONCLUSIONS: The antibody patterns against K. pneumoniae serotypes K2, K26, K36, and K50 did not discriminate between early axSpA and non-specific LBP.

OBJECTIVE: To investigate changes in whole-body magnetic resonance imaging (WBMRI) inflammatory and structural lesions in most joints and entheses in patients with rheumatoid arthritis (RA) treated with adalimumab. METHODS: WBMRI was obtained at weeks 0, 6, 16, and 52 in a 52 week follow-up study of 37 RA patients starting treatment with adalimumab. Readability and reliability of WBMRI were investigated for 76 peripheral joints, 23 discovertebral units, the sacroiliac joints, and 33 entheses. Changes in WBMRI joint and entheses counts were investigated. RESULTS: The readability of peripheral and axial joints was 82-100%, being less for elbows and small joints of the feet. For entheses, 72-100% were readable, except for entheses at the anterior chest wall, elbow, knee, and plantar fascia. The intrareader agreement was high for bone marrow oedema (BMO), bone erosion (80-100%), and enthesitis (77-100%), and slightly lower for synovitis and soft tissue inflammation (50-100%). All synovitis, BMO, and soft tissue inflammation counts decreased numerically during treatment. The 26-joint synovitis WBMRI count decreased significantly during the first 16 weeks for patients with a good European League Against Rheumatism (EULAR) response (from median 6 to 4, p < 0.05), but not for patients with a moderate or no EULAR response. There were no overall changes in structural lesions. CONCLUSIONS: WBMRI allows simultaneous monitoring of most axial and peripheral joints and entheses in RA patients and can visualize a decrease in inflammatory counts during treatment. This first WBMRI follow-up study of patients with RA encourages further investigation of the usefulness of WBMRI in RA.

OBJECTIVES: To investigate whether a treat-to-target strategy based on methotrexate (MTX) and intra-articular (IA) betamethasone suppresses magnetic resonance imaging (MRI)-determined measures of disease activity and reduces joint destruction in early rheumatoid arthritis (eRA) patients, and to investigate whether concomitant cyclosporin A (CyA) provides an additional effect. METHOD: In the 2-year randomized, double-blind, treat-to-target trial CIMESTRA, 160 patients with eRA (< 6 months) were randomized to MTX, intra-articular betamethasone and CyA, or placebo CyA. A total of 129 patients participated in the MRI substudy, and had contrast-enhanced MR images of the non-dominant hand at months 0, 6, 12, and 24. MR images were evaluated for osteitis, synovitis, tenosynovitis, bone erosion, and joint space narrowing (JSN), using validated scoring methods. RESULTS: Significant reductions were seen at 6 months in all inflammatory parameters [synovitis, mean change -1.6 (p < 0.001, Wilcoxon), tenosynovitis, -3.5 (p < 0.001), and osteitis, -1.3 (p < 0.05)] and at 12/24 months in synovitis and tenosynovitis [-1.6/-2.2 and -3.6/-3.8, respectively; all p < 0.001]. MRI signs of inflammation were not fully eliminated, and increases in erosion and JSN scores were observed at 6 months [0.4 (p < 0.01)/0.1 (p < 0.05)], 12 months [0.8 (p < 0.001)/0.3 (p < 0.01)], and 24 months [1.0 (p < 0.001)/0.4 (p < 0.001)]. Clinical measures decreased significantly (p < 0.001) at all time points. There were no consistent statistically significant differences between treatment groups. CONCLUSIONS: In this eRA treat-to-target trial, MTX and intra-articular glucocorticoids markedly reduced, but did not eliminate, MRI osteitis, synovitis, and tenosynovitis. Accordingly, minimal but statistically significant increases in bone erosion and JSN were observed. No additional effect of CyA was demonstrated.

At least 30% of patients with rheumatoid arthritis (RA) do not respond to biologic agents, which emphasizes the need of predictive biomarkers. We aimed to identify microRNAs (miRNAs) predictive of response to adalimumab in 180 treatment-naïve RA patients enrolled in the OPtimized treatment algorithm for patients with early RA (OPERA) Study, an investigator-initiated, prospective, double-blind placebo-controlled study. Patients were randomized to adalimumab 40 mg (n=89) or placebo-adalimumab (n=91) subcutaneously in combination with methotrexate. Expressions of 377 miRNAs were determined using TaqMan Human MicroRNA LDA, A Card v2.0 (Applied Biosystems). Associations between miRNAs and treatment response were tested using interaction analyses. MiRNAs with a P-value <0.05 using three different normalizations were included in a multivariate model. After backwards elimination, the combination of low expression of miR-22 and high expression of miR-886.3p was associated with EULAR good response. Future studies to assess the utility of these miRNAs as predictive biomarkers are needed.
