RESUMO
OBJECTIVES: Osteoarticular infection (OAI) is a feared complication of Staphylococcus aureus bacteraemia (SAB) and is associated with poor outcomes. We aimed to explore risk of OAI and death following SAB in patients with and without rheumatoid arthritis (RA) and to identify risk factors for OAI in patients with RA. METHODS: Danish nationwide cohort study of all patients with microbiologically verified first-time SAB between 2006-2018. We identified RA, SAB, comorbidities, and RA-related characteristics (e.g. orthopaedic implants, antirheumatic treatment) in national registries including the rheumatology registry DANBIO. We estimated cumulative incidence of OAI and death and adjusted hazard ratios (HRs, multivariate Cox regression). RESULTS: We identified 18 274 patients with SAB (n = 367 with RA). The 90-day cumulative incidence of OAI was 23.1%(95%CI 18.8; 27.6) for patients with RA and 12.5%(12.1; 13.0) for patients without RA (non-RA) (HR 1.93(1.54; 2.41)). For RA patients with orthopaedic implants cumulative incidence was 29.4%(22.9; 36.2) (HR 1.75(1.08; 2.85), and for current users of tumor necrosis factor inhibitors (TNFi) it was 41.9%(27.0; 56.1) (HR 2.27(1.29; 3.98) compared with non-users). All-cause 90-day mortality following SAB was similar in RA (35.4%(30.6; 40.3)) and non-RA (33.9%(33.2; 34.5), HR 1.04(0.87; 1.24)). CONCLUSION: Following SAB, almost one in four patients with RA contracted OAI corresponding to a doubled risk compared with non-RA. In RA, orthopaedic implants and current TNFi use were associated with approximately doubled OAI risk. One in three died within 90 days in both RA and non-RA. These findings encourage vigilance in RA patients with SAB to avoid treatment delay of OAI.
RESUMO
OBJECTIVES: In bio-naïve patients with PsA initiating a TNF inhibitor (TNFi), we aimed to identify baseline predictors of Disease Activity index for PsA in 28 joints (DAPSA28) remission (primary objective) and DAPSA28 moderate response at 6 months, as well as drug retention at 12 months across 13 European registries. METHODS: Baseline demographic and clinical characteristics were retrieved and the three outcomes investigated per registry and in pooled data, using logistic regression analyses on multiply imputed data. In the pooled cohort, selected predictors that were either consistently positive or negative across all three outcomes were defined as common predictors. RESULTS: In the pooled cohort (n = 13 369), 6-month proportions of remission, moderate response and 12-month drug retention were 25%, 34% and 63% in patients with available data (n = 6954, n = 5275 and n = 13 369, respectively). Five common baseline predictors of remission, moderate response and 12-month drug retention were identified across all three outcomes. The odds ratios (95% CIs) for DAPSA28 remission were: age, per year: 0.97 (0.96-0.98); disease duration, years (<2 years as reference): 2-3 years: 1.20 (0.89-1.60), 4-9 years: 1.42 (1.09-1.84), ≥10 years: 1.66 (1.26-2.20); men vs women: 1.85 (1.54-2.23); CRP of >10 vs ≤10 mg/l: 1.52 (1.22-1.89) and 1 mm increase in patient fatigue score: 0.99 (0.98-0.99). CONCLUSION: Baseline predictors of remission, response and adherence to TNFi therapy were identified, of which five were common for all three outcomes, indicating that the predictors emerging from our pooled cohort may be considered generalizable from country level to disease level.

OBJECTIVES: To investigate sex differences in patient-reported outcome measures (PROMs) among axSpA patients initiating their first TNFi and identify factors contributing to these disparities over the follow-up. METHODS: Data were included from 15 EuroSpA registries and consisted of axSpA patients initiating their first TNFi, with ≥2 measurements for each analysed PROM (BASDAI and BASFI, scale 0-100) taken at any time point. Linear mixed models were employed to analyse sex differences in PROMs over 24 months and to evaluate how baseline characteristics were related to the observed sex differences. RESULTS: We analysed 13 102 (38% women) in the BASDAI analyses and 10 623 (38% women) in the BASFI analyses. At follow-up, mean sex differences in BASDAI increased from 4.3 units at baseline (95% CI, 3.5-5.1)-8.0 (7.2-8.8) at 6 months, and in BASFI from 2.2 (1.4-3.1)-4.6 (3.6-5.5), with consistently worse scores in women. Baseline characteristics could not substantially account for the observed sex differences over time; however, the magnitude of the sex differences was reduced by HLA-B27 positivity, longer disease duration, and increased CRP levels, but increased by TNFi initiation in later years and peripheral arthritis. CONCLUSION: In axSpA patients initiating their first TNFi, baseline sex differences in BASDAI and BASFI increased two-fold after 6 months of treatment and persisted thereafter, with worse scores in women. Several baseline characteristics moderated the sex differences, though none could fully account for them. These findings improve our understanding of sex differences and underscore their importance in axSpA.
RESUMO
OBJECTIVE: To evaluate patient-reported outcomes (PROs) after initiation of tumor necrosis factor inhibitor (TNFi) treatment in European real-world patients with psoriatic arthritis (PsA). Further, to investigate PRO remission rates across treatment courses, registries, disease duration, sex, and age at disease onset. METHODS: Visual analog scale or numerical rating scale scores for pain, fatigue, patient global assessment (PtGA), and the Health Assessment Questionnaire-Disability Index (HAQ-DI) from 12,262 patients with PsA initiating a TNFi in 13 registries were pooled. PRO remission rates (pain ≤ 1, fatigue ≤ 2, PtGA ≤ 2, and HAQ-DI ≤ 0.5) were calculated for patients still on the treatment. RESULTS: For the first TNFi, median pain score was reduced by approximately 50%, from 6 to 3, 3, and 2; as were fatigue scores, from 6 to 4, 4, and 3; PtGA scores, from 6 to 3, 3, and 2; and HAQ-DI scores, from 0.9 to 0.5, 0.5, and 0.4 at baseline, 6, 12, and 24 months, respectively. Six-month Lund Efficacy Index (LUNDEX)-adjusted remission rates for pain, fatigue, PtGA, and HAQ-DI scores were 24%, 31%, 36%, and 43% (first TNFi); 14%, 19%, 23%, and 29% (second TNFi); and 9%, 14%, 17%, and 20% (third TNFi), respectively. For biologic-naïve patients with disease duration < 5 years, 6-month LUNDEX-adjusted remission rates for pain, fatigue, PtGA, and HAQ-DI scores were 22%, 28%, 33%, and 42%, respectively. Corresponding rates for patients with disease duration > 10 years were 27%, 32%, 41%, and 43%, respectively. Remission rates were 33%, 40%, 45%, and 56% for men and 17%, 23%, 24%, and 32% for women, respectively. For patients aged < 45 years at diagnosis, 6-month LUNDEX-adjusted remission rate for pain was 29% vs 18% for patients ≥ 45 years. CONCLUSION: In 12,262 biologic-naïve patients with PsA, 6 months of treatment with a TNFi reduced pain by approximately 50%. Marked differences in PRO remission rates across treatment courses, registries, disease duration, sex, and age at onset of disease were observed, emphasizing the potential influence of factors other than disease activity on PROs.

OBJECTIVES: The primary objective was to compare the effect of cognitive behavioural therapy for insomnia (CBT-I) to usual care on sleep efficiency, measured by polysomnography (PSG) immediately after the intervention at week 7. Secondary objectives included comparing the longer-term effect on sleep- and RA-related outcomes at week 26. METHODS: In a randomized controlled trial using a parallel group design, the experimental intervention was 6 weeks' nurse-led group-based CBT-I; the comparator was usual care. Analyses were based on the intention-to-treat (ITT) principle; missing data were statistically modelled using repeated-measures linear mixed effects models adjusted for the level at baseline. RESULTS: The ITT population consisted of 62 patients (89% women), with an average age of 58 years and an average sleep efficiency of 83.1%. At primary end point, sleep efficiency was 88.7% in the CBT-I group, compared with 83.7% in the control group (difference: 5.03 [95% CI -0.37, 10.43]; P = 0.068) measured by PSG at week 7. Key secondary outcomes measured with PSG had not improved at week 26. However, for all the patient-reported key secondary sleep- and RA-related outcomes, there were statistically highly significant differences between CBT-I and usual care (P < 0.0001), e.g. insomnia (Insomnia Severity Index: -9.85 [95% CI -11.77, -7.92]) and the RA impact of disease (RAID: -1.36 [95% CI -1.92, -0.80]) at week 26. CONCLUSION: Nurse-led group-based CBT-I did not lead to an effect on sleep efficiency objectively measured with PSG. However, CBT-I showed improvement on all patient-reported key secondary sleep- and RA-related outcomes measured at week 26.

OBJECTIVES: Identification of RA patients at a high risk of joint destruction remains challenging. The C-X-C motif chemokine 13 (CXCL13) has previously been suggested as a marker of disease activity in RA. Here, we investigate the potential of plasma CXCL13 as a marker of long-term radiographic status and progression. METHODS: CXCL13 was measured in plasma from treatment-naïve RA patients (n = 158) with an 11-year follow-up. At baseline, clinical and biochemical DASs were obtained; among these CRP, ESR, DAS in 28 joints with CRP (DAS28CRP), number of swollen joints (SJC28) and radiographic status, evaluated by total Sharp score (TSS). Age- and gender-matched healthy controls (HCs) were included. RESULTS: CXCL13 was significantly increased at baseline and decreased during treatment; however, it was not reduced to the level in HCs. At baseline, CXCL13 was associated with both CRP and ESR, but not with other markers of disease activity. Baseline CXCL13 was correlated with both TSS and radiographic progression (ΔTSS) at 11 years. With an 89% probability, levels of CXCL13 above 85 pg/ml predicted the risk of a TSS of 5 or above, after 11 years of treatment. Compared with CRP, DAS28CRP, SJC28 and ACPA status, CXCL13 was superior in predicting 11-year joint destruction. CONCLUSION: In early RA, one single measurement of plasma CXCL13 at baseline is superior to currently used clinical and serological disease markers in the prediction of long-term radiographic status and progression.

OBJECTIVES: To develop and validate in real-world patients a conversion algorithm from the Multidimensionel Health Assessment Questionnaire physical function scale (MDHAQ) to the Stanford Health Assessment Questionnaire disability index physical function scale (HAQ) score. METHODS: From the DANBIO registry, 13 391 patients with RA (n = 8983), PsA (n = 2649) and axial spondyloarthritis (axSpA, n = 1759) with longitudinal data on HAQ and MDHAQ were included, stratified by diagnosis, and randomized 1:1 into development and validation cohorts. Conversion algorithms were developed by linear regression and applied in validation cohorts. From MDHAQ, the HAQ was calculated (cHAQ) and validated against the observed HAQ for criterion, correlational and construct validity. RESULTS: For RA, we developed the conversion algorithm cHAQ = 0.15+MDHAQ*1.08, and validated it in the RA validation cohort. Criterion validity: HAQ and cHAQ had comparable discriminative power to distinguish between high and low patient global scores (standardized mean difference: HAQ:-1.29, cHAQ:-1.35). Kappa value between HAQ and cHAQ functional states indicated good agreement (0.83). Correlational validity: baseline HAQ and cHAQ, respectively, correlated well with patient global scores (r = 0.65/0.67). Bland-Altman plots showed good agreement across all functional states. Construct validity: HAQ and cHAQ discriminated equally well between patients reporting symptom state as acceptable vs not, and across responses to an external anchor. Aiming for a common algorithm, the RA conversion algorithm was validated for PsA and axSpA with similar results. CONCLUSION: This study suggests that in observational datasets with only the MDHAQ available, a simple algorithm allows valid conversion to HAQ on the group level in RA, PsA and axSpA.

OBJECTIVES: To investigate time trends in baseline characteristics and retention, remission and response rates in bio-naïve axial spondyloarthritis (axSpA) and psoriatic arthritis (PsA) patients initiating TNF inhibitor (TNFi) treatment. METHODS: Prospectively collected data on bio-naïve axSpA and PsA patients from routine care in 15 European countries were pooled. Three cohorts were defined according to year of TNFi initiation: A (1999-2008), B (2009-2014) and C (2015-2018). Retention, remission and response rates were assessed at 6, 12 and 24 months. RESULTS: In total, 27 149 axSpA and 17 446 PsA patients were included. Cohort A patients had longer disease duration compared with B and C. In axSpA, cohort A had the largest proportion of male and HLA-B27 positive patients. In PsA, baseline disease activity was highest in cohort A. Retention rates in axSpA/PsA were highest in cohort A and differed only slightly between B and C. For all cohorts, disease activity decreased markedly from 0 to 6 months. In axSpA, disease activity at 24 months was highest in cohort A, where also remission and response rates were lowest. In PsA, remission rates at 6 and 12 months tended to be lowest in cohort A. Response rates were at all time points comparable across cohorts, and less between-cohort disease activity differences were seen at 24 months. CONCLUSION: Our findings indicate that over the past decades, clinicians have implemented more aggressive treatment strategies in spondyloarthritis. This was illustrated by shorter disease duration at treatment initiation, decreased retention rates and higher remission rates during recent years.

OBJECTIVES: Serious infection is a concern for patients with inflammatory joint diseases treated with biological drugs (bDMARDs). The objectives were to compare risk of serious infection, defined as infection leading to hospitalization, in patients initiating bDMARD treatment with that in the general population and, second, to develop a simple clinical prediction model and to obtain risk estimates for individual patients. METHODS: This was a matched-cohort study based on nationwide registries in Denmark. Patients with RA, axial SpA and PsA initiating first bDMARD monitored in the DANBIO registry were matched 1:10 by age, gender and postal code with controls from the general population. The risk of serious infection during 12 months' follow-up was assessed with Cox regression. Prediction models were developed using logistic regression and compared using area under the receiver operating characteristic curve (AUC). RESULTS: We included 11 372 patients and 113 715 controls. During follow-up, 522 patients (4.6%) and 1434 controls (1.3%) developed a serious infection (hazard ratio 3.7, 95% CI 3.4, 4.1). Age-stratified risk was largely similar across diagnoses. A simple prediction model, the 'DANBIO infection risk score', based on age and a count of six clinical risk factors had moderate discriminative power (internal validation: AUC 0.69) that was comparable to that of the existing RABBIT (Rheumatoide Arthritis Beobachtung der BIologika-Therapie) Risk Score (external validation: AUC 0.68). CONCLUSION: Patients with inflammatory joint diseases initiating bDMARD treatment had a four times increased risk of serious infection compared with the general population. A simple prediction model, feasible for shared decision-making, was developed to obtain risk estimates for individual patients.

OBJECTIVES: To assess secular trends in baseline characteristics of PsA patients initiating their first or subsequent biologic DMARD (bDMARD) therapy and to explore prescription patterns and treatment rates of bDMARDs from 2006 to 2017 in the Nordic countries. METHODS: PsA patients registered in the Nordic rheumatology registries initiating any treatment with bDMARDs were identified. The bDMARDs were grouped as original TNF inhibitor [TNFi; adalimumab (ADA), etanercept (ETN) and infliximab (IFX)]; certolizumab pegol (CZP) and golimumab (GOL); biosimilars and ustekinumab, based on the date of release. Baseline characteristics were compared for the five countries, supplemented by secular trends with R2 calculations and point prevalence of bDMARD treatment. RESULTS: A total of 18 089 patients were identified (Denmark, 4361; Iceland, 449; Norway, 1948; Finland, 1069; Sweden, 10 262). A total of 54% of the patients were female, 34.3% of patients initiated an original TNFi, 8% CZP and GOL, 7.5% biosimilars and 0.3% ustekinumab as a first-line bDMARD. Subsequent bDMARDs were 25.2% original TNFi, 9% CZP and GOL, 12% biosimilars and 2.1% ustekinumab. From 2015 through 2017 there was a rapid uptake of biosimilars. The total of first-line bDMARD initiators with lower disease activity increased from 2006 to 2017, where an R2 close to 1 showed a strong association. CONCLUSION: Across the Nordic countries, the number of prescribed bDMARDs increased from 2006 to 2017, indicating a previously unmet need for bDMARDs in the PsA population. In recent years, PsA patients have initiated bDMARDs with lower disease activity compared with previous years, suggesting that bDMARDs are initiated in patients with a less active inflammatory phenotype.

OBJECTIVES: RF and ACPA are used as diagnostic tools and their presence has been associated with clinical response to some biologic DMARDs (bDMARDs) in RA. This study compared the impact of seropositivity on drug discontinuation and effectiveness of bDMARDs in patients with RA, using head-to-head comparisons in a real-world setting. METHODS: We conducted a pooled analysis of 16 observational RA registries. Inclusion criteria were a diagnosis of RA, initiation of treatment with rituximab (RTX), abatacept (ABA), tocilizumab (TCZ) or TNF inhibitors (TNFis) and available information on RF and/or ACPA status. Drug discontinuation was analysed using Cox regression, including drug, seropositivity, their interaction, adjusting for concomitant and past treatments and patient and disease characteristics and accounting for country and calendar year of bDMARD initiation. Effectiveness was analysed using the Clinical Disease Activity Index evolution over time. RESULTS: Among the 27 583 eligible patients, the association of seropositivity with drug discontinuation differed across bDMARDs (P for interaction <0.001). The adjusted hazard ratios for seropositive compared with seronegative patients were 1.01 (95% CI 0.95, 1.07) for TNFis, 0.89 (0.78, 1.02)] for TCZ, 0.80 (0.72, 0.88) for ABA and 0.70 (0.59, 0.84) for RTX. Adjusted differences in remission and low disease activity rates between seropositive and seronegative patients followed the same pattern, with no difference in TNFis, a small difference in TCZ, a larger difference in ABA and the largest difference in RTX (Lundex remission difference +5.9%, low disease activity difference +11.6%). CONCLUSION: Seropositivity was associated with increased effectiveness of non-TNFi bDMARDs, especially RTX and ABA, but not TNFis.

OBJECTIVES: To investigate the influence of RA or preclinical RA on the risk of spontaneous abortion (SA) while taking age and duration of RA into consideration. METHODS: By linkage of data from Danish national registries, we established a nationwide cohort of pregnancies in Denmark from 1 January 1977 to 31 December 2014. We used multiple logistic regression to estimate; odds ratios (OR) for SA in women with RA or preclinical RA, compared with women without, and OR for SA by maternal age in women with RA or preclinical RA. RESULTS: A total of 2 612 529 pregnancies were included. Women aged <35 years diagnosed with RA <5 years before pregnancy had an increased risk of SA (OR = 1.25 95% CI: 1.07, 1.48), compared with women without RA aged <35. Women at the same age diagnosed with RA ≥5 years before pregnancy had an OR of 1.14 (0.96-1.34), compared with women without. Among women with RA aged ≥35 years and women with preclinical RA at time of pregnancy, no increased risk of SA was found. The risk of SA increased by maternal age in both women with RA, preclinical RA and in women without. CONCLUSION: Among women aged <35 years, the risk of SA was higher in women with RA compared with women without. After the age of 35 years, the risk of SA was no different from that among women without RA, even though the risk of SA increased with increasing age.

OBJECTIVES: Most infections in patients with RA are treated in primary care with antibiotics. A small fraction require hospitalization. Only a few studies exist regarding the overall risk of infection (i.e. prescription of antibiotics or hospitalization due to infection) in patients initiating non-TNF-inhibitor therapy. In Danish RA patients initiating abatacept, rituximab and tocilizumab treatment in routine care, the aims were to compare adjusted incidence rates (IR) of infections and to estimate relative risk of infections across the drugs during 0-12 and 0-24 months. METHODS: This was an observational cohort study including all RA patients in the DANBIO registry starting a non-TNF-inhibitor from 2010 to 2017. Infections were defined as a prescription of antibiotics or hospitalization due to infection. Prescriptions, comorbidities and infections were captured through linkage to national registries. IRs of infections (age, gender adjusted) and rate ratios (as estimates of RR (relative risk)), adjusted for additional covariates) (Poisson regression) were calculated. RESULTS: We identified 3696 treatment episodes (abatacept 1115, rituximab 1017, tocilizumab 1564). At baseline, rituximab users were older and had more previous cancer. During 0-12 months, 1747 infections occurred. Age and gender-adjusted IRs per 100 person-years were as follows: abatacept: 76 (95% CI: 69, 84); rituximab: 87 (95% CI: 79, 96); tocilizumab: 77 (95% CI: 71, 84). Adjusted RRs were 0.94 (95% CI: 0.81, 1.08) for abatacept and 0.94 (95% CI: 0.81, 1.03) for tocilizumab compared with rituximab and 1.00 (95% CI: 0.88, 1.14) for abatacept compared with tocilizumab. RRs around 1 were observed after 24 months. Switchers and ever smokers had higher risk compared with biologic-naïve and never smokers, respectively. CONCLUSION: Overall infections were common in non-TNF-inhibitor-treated RA patients, with a tendency towards rituximab having the highest risk, but CIs were wide in all analyses. Confounding by indication may at least partly explain any differences.

RESUMO
The aim of this case-control study was to evaluate whether 47 single-nucleotide polymorphisms (SNPs) in steroid hormone-related genes are associated with the risk of RA and anti-TNF drug response. We conducted a case-control study in 3 European populations including 2936 RA patients and 2197 healthy controls. Of those, a total of 1985 RA patients were treated with anti-TNF blockers. The association of potentially interesting markers in the discovery population was validated through meta-analysis with data from DREAM and DANBIO registries. Although none of the selected variants had a relevant role in modulating RA risk, the meta-analysis of the linear regression data with those from the DREAM and DANBIO registries showed a significant correlation of the CYP3A4rs11773597 and CYP2C9rs1799853 variants with changes in DAS28 after the administration of anti-TNF drugs (P = 0.00074 and P = 0.006, respectively). An overall haplotype analysis also showed that the ESR2GGG haplotype significantly associated with a reduced chance of having poor response to anti-TNF drugs (P = 0.0009). Finally, a ROC curve analysis confirmed that a model built with eight steroid hormone-related variants significantly improved the ability to predict drug response compared with the reference model including demographic and clinical variables (AUC = 0.633 vs. AUC = 0.556; PLR_test = 1.52 × 10-6). These data together with those reporting that the CYP3A4 and ESR2 SNPs correlate with the expression of TRIM4 and ESR2 mRNAs in PBMCs (ranging from P = 1.98 × 10-6 to P = 2.0 × 10-35), and that the CYP2C9rs1799853 SNP modulates the efficiency of multiple drugs, suggest that steroid hormone-related genes may have a role in determining the response to anti-TNF drugs.KEY POINTS⢠Polymorphisms within the CYP3A4 and CYP2C9 loci correlate with changes in DAS28 after treatment with anti-TNF drugs.⢠A haplotype including eQTL SNPs within the ESR2 gene associates with better response to anti-TNF drugs.⢠A genetic model built with eight steroid hormone-related variants significantly improved the ability to predict drug response.

OBJECTIVE: To study the risk of a second malignant neoplasm (SMN) and mortality in patients with rheumatoid arthritis (RA) with a history of a primary cancer diagnosis and treated with biological disease-modifying antirheumatic drugs (bDMARD). METHODS: Among patients with RA (n=15 286) registered in the DANBIO Register during 2000-2011, 1678 had a primary cancer according to the Danish Cancer Registry. HRs for SMN and death were calculated. RESULTS: During follow-up there were 279 patients with RA contributing person-years to the bDMARDs use before their primary cancer diagnosis, 220 to the only after, 92 to the both before and after, while 1203 patients with RA contributed to the non-use strata. Ever use of bDMARDs was associated with a HR of 1.11 (95% CI 0.74 to 1.67) for developing a SMN compared with non-use (cancer site adjusted). The HR for death associated with bDMARD use before the primary cancer diagnosis was increased 1.53 (95% CI 1.13 to 2.09). After further adjustment for extent of the primary cancer, the HR for death was 1.20 (95% CI 0.88 to 1.63) for bDMARDs use before cancer, 1.36 (95% CI 0.78 to 2.39) for bDMARD use only after cancer and 1.22 (95% CI 0.70 to 2.13) for use both before and after the cancer. CONCLUSIONS: Among patients with RA with a history of cancer, treatment with bDMARDs was not associated with increased risk of SMN. No clear conclusion can be drawn regarding mortality in bDMARD-treated patients with RA.

RATIONALE: Sufficient levels of vitamin D seem to be essential for proper immune function, and low levels might be associated to disease activity in Rheumatoid Arthritis (RA). Most studies investigate only 25OHD and not the physiologically active vitamin D metabolite, 1,25(OH)2 D. OBJECTIVE: To investigate associations between serum level of vitamin D metabolites and disease activity parameters in 160 inflammatory active and treatment naïve early RA patients. Serum level of vitamin D metabolites (25OHD2 , 25OHD3 and 1,25(OH)2 D) was measured by isotope dilution mass spectrometry and radio-immunoassays at baseline. Disease characteristics were gender, number of tender joints, number of swollen joints, DAS28-CRP, HAQ, VAS-scores, CRP, erosive status (Total Sharp Score; TSS), ACPA and IgM-RF-status. Associations were evaluated using Spearman's and Wilcoxon rank-sum tests. The study was registered in clinical trials; trial registration number: NCT00209859. FINDINGS: Statistically significant inverse associations were found between the active metabolite 1,25(OH)2 D and DAS28-CRP (P = 0.004, rho = -0.23), HAQ (P = 0.005, rho = -0.22), CRP (P = 0.001, rho = -0.25), VASpatient-pain (P = 0.008, rho = -0.21), and a positive association was found to ACPA-status (P = 0.04). CONCLUSION: The vitamin D metabolite 1,25(OH)2 D was inversely associated with disease activity and positively associated with ACPA in treatment naïve and inflammatory active early RA. The results indicate that in RA, both the degree of inflammatory activity, and the diagnostic sensitivity and specificity might affect-or might be affected by the level of vitamin 1,25(OH)2 D.

BACKGROUND: Guidelines suggest treatment in rheumatoid arthritis (RA) to target remission, in close consultation with the patient. Our recent qualitative study of the patients' perspective on remission in RA identified 26 domains. The current study aimed to identify a short list of the most important aspects to inform future research. METHODS: Patients with RA from the Netherlands, the UK, Austria, Denmark, France and the USA completed a survey that contained all domains identified in our qualitative study. They rated domains for importance ('not important', 'important' or 'essential' to characterise a period of remission) and if important or essential, whether this domain needs to be 'less', 'almost gone' or 'gone' to reflect remission. Respondents were also asked to determine their personal top 3 most important/essential domains. Frequency of specific domains in the top 3 was calculated, and domains were sorted on the percentage of patients that evaluated a particular domain as 'essential'. RESULTS: Of 274 respondents, 75% were female, mean (SD) age 57(13) years, disease duration 12(9) years. The top 3 were as follows: pain (67%), fatigue (33%) and independence (19%); domains most frequently rated as 'essential' were as follows: pain (60%), being mobile (52%), physical function (51%), being independent (47%) and fatigue (41%). Pain needed to be less (13%), almost gone (42%) or gone (45%) to reflect remission. Similar patterns were seen for fatigue, independence, mobility and physical functioning. CONCLUSION: Patients identified pain, fatigue and independence as the most important domains of RA disease activity that need to be improved to reflect remission.

OBJECTIVES: To examine whether MRI assessed inflammation and damage in the wrist of patients with early rheumatoid arthritis (RA) are associated with patient-reported outcomes (PROs). METHODS: Wrist and hand MRIs of 210 patients with early RA from two investigator-initiated, randomised controlled studies (CIMESTRA/OPERA) were assessed according to the Outcome Measures in Rheumatology RA MRI score (RAMRIS) for synovitis, tenosynovitis, osteitis, bone erosions and joint space narrowing (JSN) at baseline, 1 and 5 years follow-up. These features, and changes therein, were assessed for associations with health assessment questionnaires (HAQ), patient global visual analogue scales (VAS-PtGlobal) and VAS-pain using Spearman's correlations, generalised estimating equations and univariate/multivariable linear regression analyses. MRI features were further tested for trends against specific hand-related HAQ items using Jonckheere trend tests. RESULTS: MRI inflammation, but not damage, showed statistically significant associations with HAQ, VAS-PtGlobal and VAS-pain for status and change scores, independently of C reactive protein and swollen joint count. MRI-assessed synovitis was most consistently associated with PROs, particularly VAS-PtGlobal and VAS-pain. MRI-assessed synovitis and tenosynovitis mean scores were positively associated with patient-reported difficulty to cut meat and open a milk carton (p<0.01), and similar patterns were seen for other hand-related HAQ items. Incorporating metacarpophalangeal joints in the analyses did not strengthen the associations between MRI pathology and PROs. CONCLUSIONS: MRI-assessed inflammation, but not damage, in early RA wrists is associated with patient-reported physical impairment, global assessment of disease activity and pain and influences the physical function in the hand. TRIAL REGISTRATION NUMBER: NCT00660647.

BACKGROUND: During the transition to rheumatoid arthritis (RA) many patients pass through a phase characterised by the presence of symptoms without clinically apparent synovitis. These symptoms are not well-characterised. This taskforce aimed to define the clinical characteristics of patients with arthralgia who are considered at risk for RA by experts based on their clinical experience. METHODS: The taskforce consisted of 18 rheumatologists, 1 methodologist, 2 patients, 3 health professionals and 1 research fellow. The process had three phases. In phase I, a list of parameters considered characteristic for clinically suspect arthralgia (CSA) was derived; the most important parameters were selected by a three-phased Delphi approach. In phase II, the experts evaluated 50 existing patients on paper, classified them as CSA/no-CSA and indicated their level of confidence. A provisional set of parameters was derived. This was studied for validation in phase III, where all rheumatologists collected patients with and without CSA from their outpatient clinics. RESULTS: The comprehensive list consisted of 55 parameters, of which 16 were considered most important. A multivariable model based on the data from phase II identified seven relevant parameters: symptom duration <1â year, symptoms of metacarpophalangeal (MCP) joints, morning stiffness duration ≥60â min, most severe symptoms in early morning, first-degree relative with RA, difficulty with making a fist and positive squeeze test of MCP joints. In phase III, the combination of these parameters was accurate in identifying patients with arthralgia who were considered at risk of developing RA (area under the receiver operating characteristic curve 0.92, 95% CI 0.87 to 0.96). Test characteristics for different cut-off points were determined. CONCLUSIONS: A set of clinical characteristics for patients with arthralgia who are at risk of progression to RA was established.
