Tocilizumab as monotherapy or combination therapy for treating active rheumatoid arthritis: a meta-analysis of efficacy and safety reported in randomized controlled trials. Arthritis Res Ther 2016; 18:211. [PMID: 27658491 PMCID: PMC5034420 DOI: 10.1186/s13075-016-1108-9] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Accepted: 09/02/2016] [Indexed: 12/26/2022] Open
Abstract
Background Previous studies in patients with rheumatoid arthritis (RA) have shown that switching to tocilizumab (TCZ) monotherapy (TCZMONO) or combination therapy (TCZCOMBI) with conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) is efficacious in reducing disease activity in patients with inadequate response to csDMARDs. However, hitherto there is no consensus on whether TCZMONO is as effective as TCZCOMBI. The objective of this study was therefore to evaluate the efficacy and safety of TCZMONO versus add-on TCZCOMBI and both TCZ therapies versus continuing the current csDMARD therapy, by performing a systematic review and meta-analyses. Method The MEDLINE, EMBASE and CENTRAL databases were searched until February 2016 for relevant randomized controlled trials (RCTs). We performed meta-analyses of Disease Activity Score in 28 joints (DAS28 < 2.6), American College of Rheumatology (ACR) 20/50/70 responses, adverse events (AEs) and serious AEs (SAEs) to compare the three different strategies, whereas a random-effect model was used for pooling relative risks (RR) and 95 % confidence intervals (CI). In addition, sensitivity analyses were performed for evaluating differences in study duration. Results In total, 13 RCTs were included in the meta-analysis, involving 6679 patients. When comparing both TCZ strategies, a marginally greater proportion of patients achieving DAS28 < 2.6 (RR 1.21; 95 % CI 1.09, 1.36) and ACR50 response (RR 1.14; 95 % CI 1.03, 1.26) was found in favor of the TCZCOMBI strategy. However, the risk of SAEs was also significantly higher using this strategy (RR 1.40; 95 % CI 1.03, 1.92, p = 0.03). Pooled effect estimates showed statistical superiority of switching to either TCZ strategy compared to continuing csDMARD therapy. Conclusions In the management of active RA, almost similar efficacy can be expected in patients unable to tolerate csDMARDs, who switch to TCZMONO compared to inadequate responders switching to add-on TCZCOMBI. Although TCZCOMBI is marginally superior to TCZMONO in achieving DAS28 < 2.6 and ACR50 response, this is at the cost of an increased risk of SAEs.

Abstract
In clinical practice, approximately one-third of patients with rheumatoid arthritis (RA) respond insufficiently to TNF-α inhibitors (TNFis). The aim of the study was to explore the use of a metabolomics to identify predictors for the outcome of TNFi therapy, and study the metabolomic fingerprint in active RA irrespective of patients’ response. In the metabolomic profiling, lipids, oxylipins, and amines were measured in serum samples of RA patients from the observational BiOCURA cohort, before start of biological treatment. Multivariable logistic regression models were established to identify predictors for good- and non-response in patients receiving TNFi (n = 124). The added value of metabolites over prediction using clinical parameters only was determined by comparing the area under receiver operating characteristic curve (AUC-ROC), sensitivity, specificity, positive- and negative predictive value and by the net reclassification index (NRI). The models were further validated by 10-fold cross validation and tested on the complete TNFi treatment cohort including moderate responders. Additionally, metabolites were identified that cross-sectionally associated with the RA disease activity score based on a 28-joint count (DAS28), erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP). Out of 139 metabolites, the best-performing predictors were sn1-LPC(18:3-ω3/ω6), sn1-LPC(15:0), ethanolamine, and lysine. The model that combined the selected metabolites with clinical parameters showed a significant larger AUC-ROC than that of the model containing only clinical parameters (p = 0.01). The combined model was able to discriminate good- and non-responders with good accuracy and to reclassify non-responders with an improvement of 30% (total NRI = 0.23) and showed a prediction error of 0.27. For the complete TNFi cohort, the NRI was 0.22. In addition, 88 metabolites were associated with DAS28, ESR or CRP (p<0.05). Our study established an accurate prediction model for response to TNFi therapy, containing metabolites and clinical parameters. Associations between metabolites and disease activity may help elucidate additional pathologic mechanisms behind RA.

Can baseline serum microRNAs predict response to TNF-alpha inhibitors in rheumatoid arthritis? Arthritis Res Ther 2016; 18:189.

Abstract
BACKGROUND In rheumatoid arthritis, prediction of response to TNF-alpha inhibitor (TNFi) treatment would be of clinical value. This study aims to discover miRNAs that predict response and aims to replicate results of two previous studies addressing this topic. METHODS From the observational BiOCURA cohort, 40 adalimumab- (ADA) and 40 etanercept- (ETN) treated patients were selected to enter the discovery cohort and baseline serum profiling on 758 miRNAs was performed. The added value of univariately selected miRNAs (p < 0.05) over clinical parameters in prediction of response was determined by means of the area under the receiver operating characteristic curve (AUC-ROC). Validation was performed by TaqMan single qPCR assays in 40 new patients. RESULTS Expression of miR-99a and miR-143 predicted response to ADA, and miR-23a and miR-197 predicted response to ETN. The addition of miRNAs increased the AUC-ROC of a model containing only clinical parameters for ADA (0.75 to 0.97) and ETN (0.68 to 0.78). In validation, none of the selected miRNAs significantly predicted response. miR-23a was the only overlapping miRNA compared to the two previous studies, however inversely related with response in one of these studies. The reasons for the inability to replicate previously proposed miRNAs predicting response to TNFi and replicate those from the discovery cohort were investigated and discussed. CONCLUSIONS To date, no miRNA consistently predicting response to TNFi therapy in RA has been identified. Future studies on this topic should meet a minimum of standards in design that are addressed in this study, in order to increase the reproducibility.

Abstract
BACKGROUND For patients with newly diagnosed rheumatoid arthritis, treatment aim is early, rapid, and sustained remission. We compared the efficacy and safety of strategies initiating the interleukin-6 receptor-blocking monoclonal antibody tocilizumab with or without methotrexate (a conventional synthetic disease-modifying antirheumatic drug [DMARD]), versus initiation of methotrexate monotherapy in line with international guidelines. METHODS We did a 2-year, multicentre, randomised, double-blind, double-dummy, strategy study at 21 rheumatology outpatient departments in the Netherlands. We included patients who had been diagnosed with rheumatoid arthritis within 1 year before inclusion, were DMARD-naive, aged 18 years or older, met current rheumatoid arthritis classification criteria, and had a disease activity score assessing 28 joints (DAS28) of at least 2·6. We randomly assigned patients (1:1:1) to start tocilizumab plus methotrexate (the tocilizumab plus methotrexate arm), or tocilizumab plus placebo-methotrexate (the tocilizumab arm), or methotrexate plus placebo-tocilizumab (the methotrexate arm). Tocilizumab was given at 8 mg/kg intravenously every 4 weeks with a maximum of 800 mg per dose. Methotrexate was started at 10 mg per week orally and increased stepwise every 4 weeks by 5 mg to a maximum of 30 mg per week, until remission or dose-limiting toxicity. We did the randomisation using an interactive web response system. Masking was achieved with placebos that were similar in appearance to the active drug; the study physicians, pharmacists, monitors, and patients remained masked during the study, and all assessments were done by masked assessors. Patients not achieving remission on their initial regimen switched from placebo to active treatments; patients in the tocilizumab plus methotrexate arm switched to standard of care therapy (typically methotrexate combined with a tumour necrosis factor inhibitor). When sustained remission was achieved, methotrexate (and placebo-methotrexate) was tapered and stopped, then tocilizumab (and placebo-tocilizumab) was also tapered and stopped. The primary endpoint was the proportion of patients achieving sustained remission (defined as DAS28 <2·6 with a swollen joint count ≤four, persisting for at least 24 weeks) on the initial regimen and during the entire study duration, compared between groups with a two-sided Cochran-Mantel-Haenszel test. Analysis was based on an intention-to-treat method. This trial was registered at ClinicalTrials.gov, number NCT01034137. FINDINGS Between Jan 13, 2010, and July 30, 2012, we recruited and assigned 317 eligible patients to treatment (106 to the tocilizumab plus methotrexate arm, 103 to the tocilizumab arm, and 108 to the methotrexate arm). The study was completed by a similar proportion of patients in the three groups (range 72-78%). The most frequent reasons for dropout were adverse events or intercurrent illness: 27 (34%) of dropouts, and insufficient response: 26 (33%) of dropouts. 91 (86%) of 106 patients in the tocilizumab plus methotrexate arm achieved sustained remission on the initial regimen, compared with 86 (84%) of 103 in the tocilizumab arm, and 48 (44%) of 108 in the methotrexate arm (relative risk [RR] 2·00, 95% CI 1·59-2·51 for tocilizumab plus methotrexate vs methotrexate, and 1·86, 1·48-2·32 for tocilizumab vs methotrexate, p<0·0001 for both comparisons). For the entire study, 91 (86%) of 106 patients in the tocilizumab plus methotrexate arm, 91 (88%) of 103 in the tocilizumab arm, and 83 (77%) of 108 in the methotrexate arm achieved sustained remission (RR 1·13, 95% CI 1·00-1·29, p=0·06 for tocilizumab plus methotrexate vs methotrexate, 1·14, 1·01-1·29, p=0·0356 for tocilizumab vs methotrexate, and p=0·59 for tocilizumab plus methotrexate vs tocilizumab). Nasopharyngitis was the most common adverse event in all three treatment groups, occurring in 38 (36%) of 106 patients in the tocilizumab plus methotrexate arm, 40 (39%) of 103 in the tocilizumab arm, and 37 (34%) of 108 in the methotrexate arm. The occurrence of serious adverse events did not differ between the treatment groups (17 [16%] of 106 patients in the tocilizumab plus methotrexate arm vs 19 [18%] of 103 in the tocilizumab arm and 13 [12%] of 108 in the methotrexate arm), and no deaths occurred during the study. INTERPRETATION For patients with newly diagnosed rheumatoid arthritis, strategies aimed at sustained remission by immediate initiation of tocilizumab with or without methotrexate are more effective, and with a similar safety profile, compared with initiation of methotrexate in line with current standards.

Determining the Lowest Optimally Effective Methotrexate Dose for Individual RA Patients Using Their Dose Response Relation in a Tight Control Treatment Approach. PLoS One 2016; 11:e0148791.

Abstract
OBJECTIVE To determine the optimal methotrexate dose in individual patients and to explore whether this optimal dose and the level of disease activity at that dose could be predicted. METHODS Data from CAMERA II trial comparing MTX and MTX with 10 mg of prednisone both in a tight control treatment strategy in early RA was used. For each patient a curve for disease activity over time was fitted and the MTX dose after which further step-up did not result in relevant improvement in disease activity anymore was determined the 'lowest optimally effective MTX dose (LOED)'. The association of demographic and clinical characteristics at baseline with this LOED and with the level of disease activity reached at LOED was studied. RESULTS In 204 (100 MTX and 104 MTX with prednisone) out of 236 patients LOED could be defined. 10 mg/wk was the most prevalent LOED in patients treated with MTX and prednisone and 10 mg/wk, 20 mg/wk and 30 mg/wk in the MTX strategy. Although the specific LOED could not reliably be predicted, higher baseline disease activity, height and lower weight were associated with higher LOEDs (i.e at least 15 mg/wk). A score was presented to decide on a starting dose of 10 mg/wk or (at least) 15 mg/wk. The level of disease activity at LOED could not be reliably predicted. CONCLUSION A starting dose of 10 mg/wk might be a good choice for most patients and is frequently already the optimal dose. However, a subgroup of patient can be determined who would require higher MTX doses.

Abstract
Objectives FRAX incorporates rheumatoid arthritis (RA) as a dichotomous predictor for predicting the 10-year risk of hip and major osteoporotic fracture (MOF). However, fracture risk may deviate with disease severity, duration or treatment. Aims were to validate, and if needed to update, UK FRAX for patients with RA and to compare predictive performance with the general population (GP). Methods Cohort study within UK Clinical Practice Research Datalink (CPRD) (RA: n=11 582, GP: n=38 755), also linked to hospital admissions for hip fracture (CPRD-Hospital Episode Statistics, HES) (RA: n=7221, GP: n=24 227). Predictive performance of UK FRAX without bone mineral density was assessed by discrimination and calibration. Updating methods included recalibration and extension. Differences in predictive performance were assessed by the C-statistic and Net Reclassification Improvement (NRI) using the UK National Osteoporosis Guideline Group intervention thresholds. Results UK FRAX significantly overestimated fracture risk in patients with RA, both for MOF (mean predicted vs observed 10-year risk: 13.3% vs 8.4%) and hip fracture (CPRD: 5.5% vs 3.1%, CPRD-HES: 5.5% vs 4.1%). Calibration was good for hip fracture in the GP (CPRD-HES: 2.7% vs 2.4%). Discrimination was good for hip fracture (RA: 0.78, GP: 0.83) and moderate for MOF (RA: 0.69, GP: 0.71). Extension of the recalibrated UK FRAX using CPRD-HES with duration of RA disease, glucocorticoids (>7.5 mg/day) and secondary osteoporosis did not improve the NRI (0.01, 95% CI −0.04 to 0.05) or C-statistic (0.78). Conclusions UK FRAX overestimated fracture risk in RA, but performed well for hip fracture in the GP after linkage to hospitalisations. Extension of the recalibrated UK FRAX did not improve predictive performance.

Abstract
There is convincing evidence for the known and unambiguously accepted beneficial effects of glucocorticoids at low dosages. However, the implementation of existing recommendations and guidelines on the management of glucocorticoid therapy in rheumatic diseases is lagging behind. As a first step to improve implementation, we aimed at defining conditions under which long-term glucocorticoid therapy may have an acceptably low level of harm. A multidisciplinary European League Against Rheumatism task force group of experts including patients with rheumatic diseases was assembled. After a systematic literature search, breakout groups critically reviewed the evidence on the four most worrisome adverse effects of glucocorticoid therapy (osteoporosis, hyperglycaemia/diabetes mellitus, cardiovascular diseases and infections) and presented their results to the other group members following a structured questionnaire for final discussion and consensus finding. Robust evidence on the risk of harm of long-term glucocorticoid therapy was often lacking since relevant study results were often either missing, contradictory or carried a high risk of bias. The group agreed that the risk of harm is low for the majority of patients at long-term dosages of ≤5 mg prednisone equivalent per day, whereas at dosages of >10 mg/day the risk of harm is elevated. At dosages between >5 and ≤10 mg/day, patient-specific characteristics (protective and risk factors) determine the risk of harm. The level of harm of glucocorticoids depends on both dose and patient-specific parameters. General and glucocorticoid-associated risk factors and protective factors such as a healthy lifestyle should be taken into account when evaluating the actual and future risk.

Abstract
Background Activation of the type I interferon (IFN) response program is described for several autoimmune diseases, including systemic lupus erythematosus (SLE), multiple sclerosis (MS), myositis (IIM) and rheumatoid arthritis (RA). While IFNα contributes to SLE pathology, IFNβ therapy is often beneficial in MS, implying different immunoregulatory roles for these IFNs. This study was aimed to investigate potential diversification of IFNα-and IFNβ-mediated response programs in autoimmune diseases. Methods Peripheral blood gene expression of 23 prototypical type I IFN response genes (IRGs) was determined in 54 healthy controls (HCs), 69 SLE (47 test, 22 validation), 149 IFNβ-treated MS (71 test, 78 validation), 160 untreated MS, 78 IIM and 76 RA patients. Patients with a type I IFN signature were selected for analysis. Results We identified IFNα- and IFNβ-specific response programs (GC-A and GC-B, respectively) in SLE and IFNβ-treated MS patients. Concordantly, the GC-A/GC-B log-ratio was positive for all SLE patients and negative for virtually all IFNβ-treated MS patients, which was confirmed in additional cohorts. Applying this information to other autoimmune diseases, IIM patients displayed positive GC-A/GC-B log-ratios, indicating predominant IFNα activity. The GC-A/GC-B log-ratio in RA was lower and approached zero in part of the patients, implying relative importance of both clusters. Remarkably, GC-A/GC-B log-ratios appeared most heterogeneous in untreated MS; half of the patients displayed GC-A dominance, whereas others showed GC-B dominance or log-ratios near zero. Conclusions Our findings show diversification of the type I IFN response in autoimmune diseases, suggesting different pathogenic roles of the type I IFNs.

Abstract
- Due to medication use, comorbidities and/or age, an increasing number of patients have an impaired immunity to infection.- Impaired immunity may lead to an increased risk of (opportunistic) infection, complications from infections, and difficulties in the diagnosis of infections.- Guided by clinical parameters, a general practitioner can classify an impaired immunity as 'clinically irrelevant', 'limitedly relevant' or 'potentially serious'.- Tocilizumab impairs the production of CRP, which makes it unreliable as an infection parameter.- In case of a suspected infection in patients with severe immunosuppression, it will often be necessary to consult a specialist as quickly as possible about further diagnostic procedures and the need for, type and administration route of antimicrobials.- In patients with an impaired immunity, adaptation of the antibiotic policy and prophylactic measures, such as vaccination, may be indicated.- Patients with (functional) asplenia should immediately start antibiotic treatment in case of fever, pending clinical evaluation by a physician.

Abstract
OBJECTIVES To review studies that address prediction of response to biologic treatment in RA and to explore the clinical utility of the studied (bio)markers. METHODS A search for relevant articles was performed in PubMed, Embase and Cochrane databases. Studies that presented predictive values or in which these could be calculated were selected. The added value was determined by the added value on prior probability for each (bio)marker. Only an increase/decrease in chance of response ⩾15% was considered clinically relevant, whereas in oncology values >25% are common. RESULTS Of the 57 eligible studies, 14 (bio)markers were studied in more than one cohort and an overview of the added predictive value of each marker is presented. Of the replicated predictors, none consistently showed an increase/decrease in probability of response ⩾15%. However, positivity of RF and ACPA in case of rituximab and the presence of the TNF-α promoter 308 GG genotype for TNF inhibitor therapy were consistently predictive, yet low in added predictive value. Besides these, 65 (bio)markers studied once showed remarkably high (but not validated) predictive values. CONCLUSION We were unable to address clinically useful baseline (bio)markers for use in individually tailored treatment. Some predictors are consistently predictive, yet low in added predictive value, while several others are promising but await replication. The challenge now is to design studies to validate all explored and promising findings individually and in combination to make these (bio)markers relevant to clinical practice.

Abstract
Background Incidence rates of non-hip major osteoporotic fractures (MOF) remain poorly characterized in the Netherlands. The Dutch FRAX® algorithm, which predicts 10-year probabilities of hip fracture and MOF (first of hip, humerus, forearm, clinical vertebral), therefore incorporates imputed MOF rates. Swedish incidence rate ratios for hip fracture to MOF (Malmo 1987–1996) were used to perform this imputation. However, equality of these ratios between countries is uncertain and recent evidence is scarce. Aims were to estimate incidence rates of hip fracture and MOF and to compare observed MOF rates to those predicted by the imputation method for the Netherlands. Methods Using hospitalisation and general practitioner records from the Dutch PHARMO Database Network (2002–2011) we calculated age-and-sex-specific and age-standardized incidence rates (IRs) of hip and other MOFs (humerus, forearm, clinical vertebral) and as used in FRAX®. Observed MOF rates were compared to those predicted among community-dwelling individuals ≥50 years by the standardized incidence ratio (SIR; 95% CI). Results Age-standardized IRs (per 10,000 person-years) of MOF among men and women ≥50 years were 25.9 and 77.0, respectively. These numbers were 9.3 and 24.0 for hip fracture. Among women 55–84 years, observed MOF rates were significantly higher than predicted (SIR ranged between 1.12–1.50, depending on age). In men, the imputation method performed reasonable. Conclusion Observed MOF incidence was higher than predicted for community-dwelling women over a wide age-range, while it agreed reasonable for men. As miscalibration may influence treatment decisions, there is a need for confirmation of results in another data source. Until then, the Dutch FRAX® output should be interpreted with caution.

Economic evaluation of a tight-control treatment strategy using an imaging device (handscan) for monitoring joint inflammation in early rheumatoid arthritis. Clin Exp Rheumatol 2015; 33:831-838.

Abstract
OBJECTIVES To evaluate the cost-effectiveness of a tight-control treatment strategy using the handscan (TCHS) compared to using only clinical assessments (TC) and compared to a general non-tight-control treatment strategy (usual care; UC) in early rheumatoid arthritis (RA). METHODS Data from 299 early RA patients from the CAMERA trial were used. Clinical outcomes were extrapolated to Quality Adjusted Life Years (QALYs) and costs using a Markov model. Costs and QALYs were compared between the TC and UC treatment strategy arm of the CAMERA trial and a simulated tight-control treatment strategy using the handscan (TCHS). Incremental Cost-Effectiveness Ratios (ICERs) were calculated and several scenario analyses performed. All analyses were performed probabilistically to obtain confidence intervals and costs-effectiveness planes and acceptability curves. RESULTS In TCHS, €4,660 (95% CI -€11,516 to €2,045) was saved and 0.06 (95% CI 0.01 to 0.11) QALYs were gained when compared to UC, with an ICER of €77,670 saved per QALY gained. Ninety-one percent (91%) of simulations resulted in less costs and more QALYs. TCHS resulted in comparable costs or even limited savings €642 (95% CI -€6,903 to €5,601)) and comparable QALYs to TC. In all scenario analyses, TCHS and TC were found to be cost effective as compared to UC. CONCLUSIONS A tight-control treatment strategy is highly cost-effective compared to a non-tight-control approach in early RA. Using the handscan as a monitoring device might facilitate implementation of tight-control treatment strategy at comparable costs and with comparable effects. This approach should be investigated further.

Abstract
Objectives In rheumatoid arthritis (RA), treat-to-target strategies require instruments for valid detection of joint inflammation. Therefore, imaging modalities are increasingly used in clinical practice. Optical spectral transmission (OST) measurements are non-invasive and fast and may therefore have benefits over existing imaging modalities. We tested whether OST could measure disease activity validly in patients with RA. Methods In 59 patients with RA and 10 patients with arthralgia, OST, joint counts, Disease Activity Score (DAS) 28 and ultrasonography (US) were performed. Additionally, MRI was performed in patients with DAS28<2.6. We developed and validated within the same cohort an algorithm for detection of joint inflammation by OST with US as reference. Results At the joint level, OST and US performed similarly inproximal interphalangeal-joints (area under the receiver-operating curve (AUC) of 0.79, p<0.0001) andmetacarpophalangeal joints (AUC 0.78, p<0.0001). Performance was less similar in wrists (AUC 0.62, p=0.006). On the patient level, OST correlated moderately with clinical examination (DAS28 r=0.42, p=0.001), and US scores (r=0.64, p<0.0001). Furthermore, in patients with subclinical and low disease activity, there was a correlation between OST and MRI synovitis score (RAMRIS (Rheumatoid Arthritis MRI Scoring) synovitis), r=0.52, p=0.005. Conclusions In this pilot study, OST performed moderately in the detection of joint inflammation in patients with RA. Further studies are needed to determine the diagnostic performance in a new cohort of patients with RA.

Contribution of the subjective components of the disease activity score to the response to biologic treatment in rheumatoid arthritis. Arthritis Care Res (Hoboken) 2015; 67:923-8. [PMID: 25504811 DOI: 10.1002/acr.22532] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2014] [Revised: 11/10/2014] [Accepted: 12/02/2014] [Indexed: 01/26/2023]
Abstract
OBJECTIVE A significant proportion of patients with rheumatoid arthritis do not respond adequately to biologic treatment. We hypothesized that lack of response to (biologic) disease-modifying antirheumatic drugs (DMARDs) is high in patients in whom the subjective, patient-reported component of the Disease Activity Score 28 (DAS28) is high at baseline. The primary aim of our present study was to investigate the contribution of the more subjective versus the objective components of the DAS28 to response to biologic agents in RA patients, as well as the changes in this contribution over time. The secondary aim was to examine whether the value of this subjective contribution at baseline affects the response to treatment. METHODS The DAS28-P (the subjective components of the DAS28 relative to the total DAS28) was calculated. Patients were derived from the computer-assisted Management in Early Rheumatoid Arthritis Trial-II and the Biologicals and Outcome Compared and Predicted in Utrecht Region in Rheumatoid Arthritis Study. Ordinal logistic regression analyses were performed. RESULTS The DAS28-P score at baseline was not associated with the level of response according to European League Against Rheumatism criteria at 3 months. Overall, a significant reduction in the DAS28-P score was observed 3 months after start of treatment, showing a greater reduction of the combined subjective components in good responders. CONCLUSION The results reject the hypothesis that the lack of response to biologic DMARDs is especially high in patients in whom the patient-reported component of the DAS28 is high at baseline; these subjective components are not linked to treatment response.

Abstract
OBJECTIVE Treatment in general is mostly directly aimed at disease activity, and measures such as the DAS28 might therefore present important additional information. Our aim was to develop and validate a model that uses a combination of disease activity (DAS28) and HAQs to estimate EuroQoL 5-dimension scale (EQ5D) utilities. METHODS Longitudinal data from a cohort study in RA patients from the Utrecht Rheumatoid Arthritis Cohort study Group (Stichting Reumaonderzoek Utrecht) who started treatment with a biologic drug were used for mapping and validation. All 702 observations, including DAS28, HAQ and EQ5D assessed at the same time points, were used. The observations were randomly divided into a subset for development of the model (n = 428 observations) and a subset for validation (n = 274). A stepwise multivariable regression analysis was used to test the association of DAS28 (components) and HAQ (domains) with EQ5D. Model performance was assessed using the explained variance (R(2)) and root mean square errors. Observed and predicted utility scores were compared to check for under- or overestimation of the scores. Finally, the performance of the model was compared with published mapping models. RESULTS Lower DAS28 score and HAQ items dressing and grooming, arising, eating, walking and activities were associated with higher EQ5D scores. The final model had an explained variance of 0.35 and a lower root mean square error as compared with other models tested. The agreement between predicted and observed scores was fair. CONCLUSION HAQ components estimate EQ5D better than total HAQ. Adding DAS28 to HAQ components does not result in better utility estimations.

Abstract
OBJECTIVE To relate systemic biochemical markers of joint metabolism to presence, incidence, and progression of early-stage radiographic knee and/or hip osteoarthritis (OA). METHOD The cartilage markers uCTX-II, sCOMP, sPIIANP, and sCS846, bone markers uCTX-I, uNTX-I, sPINP, and sOC, and synovial markers sHA and sPIIINP were assessed by enzyme-linked immunosorbent assay or radioactive immunoassay in baseline samples of CHECK (Cohort Hip and Cohort Knee), a cohort study of early-stage symptomatic knee and/or hip OA. Knee and hip radiographs were obtained at baseline and 5-year follow-up. Presence of OA at baseline was defined as Kellgren and Lawrence (K&L) = 1 (maximum observed). Incidence of OA was defined as K&L = 0 at baseline and K&L ≥ 1 at 5-year follow-up. Progression of OA was defined as K&L = 1 at baseline and K&L ≥ 2 at 5-year follow-up. RESULTS Data were available for 801 subjects at baseline and for 723 subjects at both baseline and 5-year follow-up. Multiple cartilage and synovial markers showed positive associations with presence and progression of knee and hip OA and with incidence of hip OA, except for negative associations of uCTX-II and sCOMP with incidence of knee OA. uCTX-II and sCOMP showed multiple interactions with other biomarkers in their associations with knee and hip OA. Bone markers were positively associated with presence of radiographic knee OA, but negatively associated with progression of radiographic hip OA. CONCLUSION Especially metabolism in cartilage and synovial matrix appear to be of relevance in knee and hip OA. The role of bone metabolism appears to differ between knee and hip OA.

Abstract
Glucocorticoid (GC) therapy is widely accepted as effective treatment for many inflammatory conditions. However, the potential of GC to produce adverse effects may prompt both patients and prescribing doctors to take a critical view on these important drugs. The increasing awareness of potential side effects suggests that the improvement of the benefit:risk ratio represents both a current need and an ongoing challenge. The developing and detailed knowledge on mechanisms of GC action has resulted in exploration of numerous approaches to optimise treatments with these important drugs. Most advanced is a chronotherapeutic formulation of prednisone (termed modified- or delayed-release prednisone) that has been recently approved in many European and other countries, and very recently also in the United States. Another interesting example is the development of selective GC receptor (GR) agonists, with clinical studies being currently underway. The development of so called liposomal GC is ongoing. However, another approach, the synergistic combination of prednisolone and dipyridamole, has been recently discontinued because a phase 2b study with the treatment in patients with rheumatoid arthritis showed a statistically significant improvement in disease activity score measured in 28 joints (DAS28) compared with placebo, but not compared with prednisolone alone. Other interesting developments and promising concepts include the development of nitrosteroids, targeting the membrane-bound GR and the use of extracts of the medicinal plant Tripterygium wilfordii Hook F.

Abstract
OBJECTIVE To identify subgroups of pain trajectories in patients with symptomatic knee osteoarthritis (OA), and to explain these different trajectories by patient characteristics, lifestyle, and coping factors, as well as radiographic features. METHODS Longitudinal data of pain severity (0-10) from 5 years of followup of the CHECK (Cohort Hip and Cohort Knee) study was used. Latent class growth analysis identified homogeneous subgroups with distinct trajectories of pain. Multinomial regression analysis was used to examine different lifestyle and coping characteristics between the trajectories. RESULTS In longitudinal pain data of 5 years of followup in 705 participants, 3 pain trajectories were identified: marginal, mild, and moderate pain trajectories. Compared with the marginal pain trajectory, the mild and moderate pain trajectories can be characterized by the following baseline variables: body mass index (BMI) > 25, additional hip pain, low education level, using the coping strategy "worrying," and having ≥ 3 comorbidities. Moderate pain trajectory can be supplemented with the Kellgren-Lawrence grading scale grade ≥ 2 radiological change. CONCLUSION Three trajectories of pain were identified. Participants with a BMI > 25, secondary school as highest education level, having at least 3 comorbidities, additional hip pain, and/or whose coping style is worrying are more likely to develop a moderate or mild pain trajectory compared with those without these characteristics. In the management of knee pain in people with early symptomatic OA, attention should also be given to additional factors such as hip pain, other comorbidities, passive coping strategy, and obesity.

Abstract
Glucocorticoids (GC) are now being used for over 65 years in the treatment of rheumatoid arthritis (RA). There is by now good evidence for their disease modifying effect, especially in early RA. When used in a dosage of 7.5-10 mg most adverse effects can be quite well handled, though monitoring and awareness for infections are important. The CAMERA II study is discussed, in which patients with early RA were treated with a tight control scheme of climbing dosages of methotrexate plus either 10 mg prednisone daily or placebo. After the two years of the trial, 70% of the patients treated with tight control strategy without GC had no erosions versus 82% of the patients treated with additional prednisone. Remission was reached more often and earlier on in the strategy with prednisone compared to the strategy with placebo. It may be suggested that GC have a greater beneficial effect on joint structure than can be explained by their anti-inflammatory effects only.

Abstract
UNLABELLED Long-term persistence with anti-osteoporosis drugs and determinants for discontinuation among fracture patients were examined. Persistence was 75.0 and 45.3 % after 1 and 5 years, respectively. Those aged ≥80 years were at increased risk of early discontinuation. Within 1 year after discontinuation, 24.3 % restarted therapy, yet 47.0 % persisted for 1 year. INTRODUCTION The risk of osteoporotic fracture can effectively be reduced with use of anti-osteoporosis drugs. However, little is known about persistence with these drugs after fracture where subsequent fracture risk is high. The aims were to determine long-term persistence with anti-osteoporosis drugs among fracture patients, including its determinants, and to describe restart and subsequent persistence. METHODS A cohort study was conducted within the Dutch PHARMO Database Network. Patients aged ≥50 years (n = 961) who received anti-osteoporosis drugs within 1 year after fracture, but not in the preceding year, were included (2002-2011). Persistence (defined as the proportion on treatment) and the proportion restarting after discontinuation were estimated using Kaplan-Meier analyses. Time-dependent Cox regression was used to identify determinants of non-persistence including age, sex, initial dosage regime, fracture type, comorbidities, and drug use. RESULTS Persistence with anti-osteoporosis drugs was 75.0 % (95 % confidence interval (CI) 72.0-77.7) and 45.3 % (95 % CI 40.4-50.0) after 1 and 5 years, respectively. A significant determinant of non-persistence was age ≥80 years (reference 50-59 years: adjusted hazard ratio [adj. HR] 1.65; 95 % CI 1.15-2.38). This effect was not constant over time (≤360 days following initiation: adj. HR 2.07; 95 % CI 1.27-3.37; >360 days: adj. HR 1.08; 95 % CI 0.62-1.88). Within 1 year after discontinuation, 24.3 % (95 % CI 20.1-29.2) restarted therapy, yet 47.0 % persisted for 1 year. CONCLUSIONS This study identified suboptimal persistence with anti-osteoporosis drugs among fracture patients. Major target groups for measures aimed to improve persistence may be those aged >80 years and those restarting therapy.

Abstract
OBJECTIVE To investigate whether the potential of abatacept to inhibit vigorous CD1c myeloid dendritic cell (MDC)-driven activation of naive and memory CD4 T cells is abrogated in the presence of T cell-activating cytokines. METHODS CD4 T cell subsets (naive [Tn], central memory [Tcm], and effector memory [Tem] T cells) were isolated from the peripheral blood (PB) of healthy controls and the PB and synovial fluid (SF) of rheumatoid arthritis (RA) patients. CD4 T cells were cocultured with autologous, thymic stromal lymphopoietin (TSLP)-primed CD1c MDCs in the presence or absence of abatacept (CTLA-4Ig) and/or interleukin-7 (IL-7) or IL-15. Subsequently, T cell proliferation and cytokine production were measured. RESULTS The percentages of each CD4 T cell subset from the circulation of healthy controls and RA patients were comparable and mainly consisted of Tn and Tcm cells, whereas the SF of RA patients mainly consisted of Tcm and Tem cells. Activation of CD4 T cell subsets by TSLP-primed MDCs from the RA PB was completely blocked by abatacept. Addition of IL-7 or IL-15 to the cocultures strongly increased CD4 T cell activation and overruled the inhibitory capacity of abatacept. IL-7-induced reversal was associated with robust induction of interferon-γ, tumor necrosis factor α, and IL-17 secretion. Similarly, CD4 T cell proliferation induced by TSLP-primed MDCs from the SF of RA patients was strongly blocked by abatacept, but this inhibitory effect was vigorously overruled in the presence of IL-7. CONCLUSION These findings indicate that the presence of T cell-activating cytokines such as IL-7 or IL-15 in the joints of RA patients reduces the capacity of abatacept to inhibit MDC-driven CD4 T cell activation. This mechanism may be one explanation for the partial, and sometimes absent, response to abatacept therapy in a subset of patients.

Abstract
OBJECTIVE To evaluate whether a disease activity guided strategy of dose reduction of two tumour necrosis factor (TNF) inhibitors, adalimumab or etanercept, is non-inferior in maintaining disease control in patients with rheumatoid arthritis compared with usual care. DESIGN Randomised controlled, open label, non-inferiority strategy trial. SETTING Two rheumatology outpatient clinics in the Netherlands, from December 2011 to May 2014. PARTICIPANTS 180 patients with rheumatoid arthritis and low disease activity using adalimumab or etanercept; 121 allocated to the dose reduction strategy, 59 to usual care. INTERVENTIONS Disease activity guided dose reduction (advice to stepwise increase the injection interval every three months, until flare of disease activity or discontinuation) or usual care (no dose reduction advice). Flare was defined as increase in DAS28-CRP (a composite score measuring disease activity) greater than 1.2, or increase greater than 0.6 and current score of at least 3.2. In the case of flare, TNF inhibitor use was restarted or escalated. MAIN OUTCOME MEASURES Difference in proportions of patients with major flare (DAS28-CRP based flare longer than three months) between the two groups at 18 months, compared against a non-inferiority margin of 20%. Secondary outcomes included TNF inhibitor use at study end, functioning, quality of life, radiographic progression, and adverse events. RESULTS Dose reduction of adalimumab or etanercept was non-inferior to usual care (proportion of patients with major flare at 18 months, 12% v 10%; difference 2%, 95% confidence interval -12% to 12%). In the dose reduction group, TNF inhibitor use could successfully be stopped in 20% (95% confidence interval 13% to 28%), the injection interval successfully increased in 43% (34% to 53%), but no dose reduction was possible in 37% (28% to 46%). Functional status, quality of life, relevant radiographic progression, and adverse events did not differ between the groups, although short lived flares (73% v 27%) and minimal radiographic progression (32% v 15%) were more frequent in dose reduction than usual care. CONCLUSIONS A disease activity guided, dose reduction strategy of adalimumab or etanercept to treat rheumatoid arthritis is non-inferior to usual care with regard to major flaring, while resulting in the successful dose reduction or stopping in two thirds of patients.Trial registration Dutch trial register (www.trialregister.nl), NTR 3216.

Abstract
OBJECTIVE Although the Computer Assisted Management in Early Rheumatoid Arthritis Trial-II (CAMERA-II) showed favorable clinical effects in the most intensive methotrexate (MTX)-based strategy with prednisone (MTX ± prednisone) compared to that with placebo (MTX + placebo), this beneficial difference was only seen in 1 of the 3 analyses of remission. Our objective was to investigate whether the Continuity Rewarded (ConRew) score and a simple sum score would better reveal differences regarding remission between the 2 treatment arms of CAMERA-II. Furthermore, we investigated whether the patient vector graph, which plots on patient level, would add visual information on remission compared to a conventional box plot only, which displays data on the group level. METHODS The ConRew method, which awards continuous periods of remission with a higher score, was applied, in addition to a simple sum score of remission periods of 4 weeks. A patient vector graph was compared with box plots. RESULTS Both the mean ± SD simple sum score and the ConRew score of remission were significantly higher (favorable) in the MTX + prednisone strategy group versus the MTX + placebo group, respectively: 9 ± 7 versus 12 ± 8; P = 0.003, and 23 ± 16 versus 17 ± 14; P = 0.004. The patient vector graphs show a visual pattern of more and longer periods of remission in the MTX + prednisone strategy and visually add information to the box plots. CONCLUSION The simple sum of remission periods, the ConRew score, and the patient vector graph add understanding and discrimination to the analysis of the remission outcome in CAMERA-II.

Abstract
After the successful treatment of inflammatory rheumatic diseases with targeted therapies, the greatest challenge in rheumatic diseases remains the treatment of the most common chronic joint disorder, osteoarthritis. Osteoarthritis (OA) commonly affects the knee, with an age-standardised and sex-standardised incidence of 240 per 100.000 person-years. With the aging of the population and rising obesity throughout the world, it is anticipated that the burden of OA will increase and become a major problem for health systems globally. Given this background, proper guidance on the management of OA is needed. This issue has been addressed over recent months in updated guidelines or recommendations detailing three treatment modalities: non-pharmacological, pharmacological and surgical. It should be noted, that OA is not a uniform disease entity. In some patients, progression of the disease seems to be driven by cartilage factors, in others by bone factors or by inflammatory factors. Ongoing research aims to identify potential biomarkers for these different forms of OA. Research is also underway into disease modifying OA drugs (DMOADs) that target different aspects of the disease, treatments for OA pain, and cell-based therapies.

Abstract
This paper reviews the clinical effects on bone of 10 mg of prednisone daily in early rheumatoid arthritis, given for 2 years in the Utrecht Study and in the second CAMERA (Computer- Assisted Management in Early Rheumatoid Arthritis) Study, and addresses the question whether there were joint-sparing effects and whether these were offset by adverse effects, especially osteoporosis. We conclude that a 2-year adjunct treatment with 10 mg of prednisone daily increases the benefits of disease-modifying antirheumatic drug therapy and has joint-sparing properties, even if added to the tight control methotrexate-based strategy aiming for remission. Importantly, with good control of inflammation and adequate use of calcium, vitamin D and bisphosphonates - according to national or international guidelines - steroid-induced osteoporosis is rare over 2 years.

Abstract
OBJECTIVES To identify the first time point of an MRI-verified response to certolizumab pegol (CZP) therapy in patients with rheumatoid arthritis (RA). METHODS Forty-one patients with active RA despite disease-modifying antirheumatic drug therapy were randomised 2:1 to CZP (CZP loading dose 400 mg every 2 weeks at weeks 0-4; CZP 200 mg every 2 weeks at weeks 6-16) or placebo→CZP (placebo at weeks 0-2; CZP loading dose at weeks 2-6; CZP 200 mg every 2 weeks at weeks 8-16). Contrast-enhanced MRI of one hand and wrist was acquired at baseline (week 0) and weeks 1, 2, 4, 8 and 16. All six time points were read simultaneously, blinded to time, using the Outcome Measures in Rheumatology Clinical Trials RA MRI scoring system. Primary outcome was change in synovitis score in the CZP group; secondary outcomes were change in bone oedema (osteitis) and erosion scores and clinical outcome measures. RESULTS Forty patients were treated (27 CZP, 13 placebo→CZP), and 36 (24 CZP, 12 placebo→CZP) completed week 16. In the CZP group, there were significant reductions from baseline synovitis (Hodges-Lehmann estimate of median change, -1.5, p=0.049) and osteitis scores (-2.5, p=0.031) at week 16. Numerical, but statistically insignificant, MRI inflammation reductions were observed at weeks 1-2 in the CZP group. No significant change was seen in bone erosion score. Improvements across all clinical outcomes were seen in the CZP group. CONCLUSIONS CZP reduced MRI synovitis and osteitis scores at week 16, despite small sample size and the technical challenge of reading six time points simultaneously. This study provides essential information on optimal MRI timing for subsequent trials. TRIAL REGISTRATION NUMBER ClinicalTrials.gov, NCT01235598.

Abstract
Introduction The aim of this study was to investigate PD-1/PD-L1 involvement in the hyporesponsiveness of rheumatoid arthritis (RA) synovial fluid (SF) CD4 T cells upon stimulation by thymic stromal lymphopoietin (TSLP)–primed CD1c myeloid dendritic cells (mDCs). Methods Expression of PD-1 on naïve (Tn), central memory (Tcm) and effector memory (Tem) CD4 T cell subsets was assessed by flow cytometry. PD-L1 expression and its regulation upon TSLP stimulation of mDCs from peripheral blood (PB) and SF of RA patients were investigated by quantitative RT-PCR and flow cytometry. The involvement of PD-1/PD-L1 interactions in SF T cell hyporesponsiveness upon (TSLP-primed) mDC activation was determined by cell culture in the presence of PD-1 blocking antibodies, with or without interleukin 7 (IL-7) as a recognized suppressor of PD-1 expression. Results PD-1 expression was increased on CD4 T cells derived from SF compared with PB of RA patients. TSLP increased PD-L1 mRNA expression in both PB and SF mDCs. PD-L1 protein expression was increased on SF mDCs compared with PB mDCs and was associated with T cell hyporesponsiveness. Blockade of PD-1, as well as IL-7 stimulation, during cocultures of memory T cells and (TSLP-primed) mDCs from RA patients significantly recovered T cell proliferation. Conclusion SF T cell hyporesponsiveness upon (TSLP-primed) mDC stimulation in RA joints is partially dependent on PD-1/PD-L1 interactions, as PD-1 and PD-L1 are both highly expressed on SF T cells and mDCs, respectively, and inhibiting PD-1 availability restores T cell proliferation. The potential of IL-7 to robustly reverse this hyporesponsiveness suggests that such proinflammatory cytokines in RA joints strongly contribute to memory T cell activation.

Abstract
OBJECTIVES To investigate the predictive value of ultrasound (US) characteristics for the effect of intra-articular glucocorticoids in knee osteoarthritis (OA). METHODS In this prospective cohort study, 62 patients with symptomatic knee OA (clinical knee OA criteria, pain>4 on a Numerical Rating Scale (NRS; 0-10)) received an intra-articular glucocorticoid injection (40 mg triamcinolone acetonide). Patients with NRS pain ≤4 at 4 weeks were defined as responders. On inclusion, demographics, clinical data (body mass index, local swelling) knee x-rays and knee injury and Osteoarthritis Outcome Score (KOOS) questionnaire were collected. Six US features were assessed including: effusion, synovial hypertrophy, Baker's cyst, infrapatellar bursitis, meniscal protrusion and cartilage thickness. Stepwise multiple logistic regression analyses with forward selection were conducted to identify possible predictors. RESULTS At 4 weeks, 42% of the study participants reached a NRS ≤4; an effect comparable to existing literature. Regression analyses showed that patients who used analgesics at baseline were less likely to have a good response. The small proportion of patients with infrapatellar bursitis was more likely to respond to the injection. CONCLUSIONS No patient, disease or US characteristic of inflammation, turned out to be a reliable and clinically meaningful predictor for the effect of intra-articular glucocorticoids after four weeks in knee OA.

Abstract
OBJECTIVE To enhance guideline-based nonsurgical management of osteoarthritis (OA), a multidisciplinary stepped-care strategy has been implemented in clinical practice. This study aimed to describe health care use after implementation of this strategy and to identify factors related to such use at multiple levels. METHODS For this 2-year observational prospective cohort, patients with symptomatic hip or knee OA were included by their general practitioner. Activities aligned with patients and health care providers were executed to implement the strategy. Health care use was described as the cumulative percentage of "users" for each modality recommended in the strategy. Determinants were identified at the level of the patient, general practitioner, and practice using backward stepwise logistic multilevel regression models. RESULTS Three hundred thirteen patients were included by 70 general practitioners of 38 practices. Their mean ± SD age was 64 ± 10 years and 120 (38%) were men. The most frequently used modalities were education, acetaminophen, lifestyle advice, and exercise therapy, which were used by 242 (82%), 250 (83%), 214 (73%), and 187 (63%) patients, respectively. Fourteen percent of the overweight patients reported being treated by a dietician. Being female, having an active coping style, using the booklet "Care for Osteoarthritis," and having limitations in functioning were recurrently identified as determinants of health care use. CONCLUSION After implementation of the stepped-care strategy, most recommended nonsurgical modalities seem to be well used. Health care could be further improved by providing dietary therapy in overweight patients and making more efforts to encourage patients with a passive coping style to use nonsurgical modalities.

Abstract
BACKGROUND Anti-tumor necrosis factor (TNF) agents are effective in treating patients with rheumatoid arthritis (RA), but they are associated with (dose-dependent) adverse effects and high costs. To prevent overtreatment, several trials have assessed the effectiveness of down-titration compared with continuation of the standard dose. OBJECTIVES To evaluate the benefits and harms of down-titration (dose reduction, discontinuation or disease activity guided dose tapering) of anti-TNF agents (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab) on disease activity, functioning, costs, safety and radiographic damage compared with usual care in patients with RA and low disease activity. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), Issue 8, 2013; Ovid MEDLINE (1946 to 8 September 2013); EMBASE (1947 to 8 September 2013); Science Citation Index (Web of Science); and conference proceedings of the American College of Rheumatology (2005 to 2012) and European League against Rheumatism (2005 to 2013). We contacted authors of the seven included studies to ask for additional information on their study; five responded. SELECTION CRITERIA Randomised controlled trials (RCTs) and controlled clinical trials (CCTs) comparing down-titration (dose reduction, discontinuation, disease activity-guided dose tapering) of anti-TNF agents (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab) to usual care/no down-titration in patients with RA and a low disease activity state. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, assessed risk of bias and extracted data. MAIN RESULTS Six RCTs and one CCT (total 1203 participants), reporting anti-TNF down-titration, were included. Three studies (559 participants) reported anti-TNF dose reduction compared with anti-TNF continuation. Five studies (732 participants) reported anti-TNF discontinuation compared with anti-TNF continuation (two studies assessed both anti-TNF discontinuation and dose reduction), and one study assessed disease activity-guided anti-TNF dose tapering (137 participants). These studies include only adalimumab and etanercept; controlled data on other anti-TNF agents are absent. Two studies were available in full text; one was assessed as having low risk of bias and the other high risk. Five studies were available only as one or more abstracts. Because data provided in these abstracts were limited, risk of bias was unclear. Clinical heterogeneity between the trials was high.Dose reduction of anti-TNF (etanercept data only) showed no statistically significant or clinical relevant difference in disease activity score in 28 joints (DAS28) (mean difference (MD) 0.10, 95% confidence interval (CI) -0.11 to 0.31) (scale 0.9 to 8; higher score indicates worse disease activity). The proportion of participants who maintained low disease activity was slightly lower among participants given reduced doses of the anti-TNF agent (risk ratio (RR) 0.87, 95% CI 0.78 to 0.98, absolute risk difference (ARD) 9%). Radiographic outcome was slightly worse, but this was not clinically meaningful, compared with continuation of anti-TNF (MD 0.11, 95% CI 0.08 to 0.14) (scale 0 to 448; higher score indicates greater joint damage). Function was not statistically different between anti-TNF dose reduction and continuation (MD 0.10, 95% CI 0.00 to 0.20) (scale 0 to 3; higher score indicates worse functioning). Reinstalment of anti-TNF after failure of dose reduction showed a 5% risk of persistent flare. Data on numbers of serious adverse events (SAEs) (RR 0.58, 95% CI 0.23 to 1.45, ARD -2%) and withdrawals due to adverse events (AEs) (RR 0.57, 95% CI 0.17 to 1,92, ARD -1%) were inconclusive. Most outcomes were based on moderate quality evidence.Participants who discontinued anti-TNF (adalimumab and etanercept data) had higher mean DAS28 (DAS28-erythrocyte sedimentation rate (ESR): MD 1.10, 95% CI 0.86 to 1.34) and DAS28-C-reactive protein (CRP): MD 0.57 95% CI -0.09 to 1.23) and were less likely to maintain a low disease activity state (RR 0.43, 95% CI 0.27 to 0.68, ARD 40%). Also, radiographic and functional outcomes are worse after anti-TNF discontinuation (MD 0.66, 95% CI 0.63 to 0.69, and MD 0.30, 95% CI 0.19 to 0.41, respectively). Data on numbers of SAEs (RR 1.26, 95% CI 0.61 to 2.63, ARD 2%) and withdrawals due to AEs (RR 0.72, 95% CI 0.23 to 2.24, ARD -1%) were inconclusive. Most outcomes were based on moderate quality evidence.The one study comparing disease activity-guided anti-TNF dose tapering (adalimumab and etanercept data) reported no statistically significant differences in functional outcomes (MD 0.20, 95% CI -0.02 to 0.42). Significantly higher mean disease activity was found among participants with tapered anti-TNF at study end (MD 0.50, 95% CI 0.11 to 0.89). No full text of this trial was available for this review. No other major outcomes were reported. All outcomes were based on low quality evidence. AUTHORS' CONCLUSIONS We can conclude, mostly based on moderate quality evidence, that non-disease activity guided dose reduction of etanercept 50 mg weekly to 25 mg weekly, after at least three to 12 months of low disease activity, seems as effective as continuing the standard dose with respect to disease activity and functional outcomes, although dose reduction significantly induces minimal and not clinically meaningful differences in radiological progression. Discontinuation (also without disease activity-guided adaptation) of adalimumab and etanercept is inferior to continuation of treatment with respect to disease activity and radiological outcomes and function. Disease activity-guided dose tapering of adalimumab and etanercept seems slightly inferior to continuation of treatment with respect to disease activity, with no difference in function. However the only study investigating this comparison included lower than projected numbers of participants.Caveats of this review are that available data are limited. Also, the heterogeneity between studies and the suboptimal design choices (including absence of disease activity-guided dose reduction and discontinuation and use of superiority designs) limit definitive conclusions. None of the included studies assessed long-term safety and costs, although these factors are specific reasons why clinicians consider lowering the dose or stopping the administration of anti-TNF agents.Future research should include other anti-TNF agents; assessment of disease activity, function and radiographic outcomes after longer follow-up; and assessment of long-term safety, cost-effectiveness and predictors for successful down-titration. Also use of a validated flare criterion, non-inferiority designs and disease activity-guided instead of fixed-dose tapering or stopping would allow researchers to better interpret study findings and generalise the information to clinical practice.

Abstract
OBJECTIVES To explore the association between S100A8/A9 serum levels with clinical and structural characteristics of patients with established knee, hip, or hand osteoarthritis (OA). METHOD A cross-sectional exploratory study was conducted with 162 OA patients. Measures for pain, stiffness, and function included the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) questionnaire or the Australian Canadian Osteoarthritis Hand (AUSCAN) Index and for structural abnormalities, osteophytes and joint space narrowing grades. The association between S100A8/A9 and clinical or structural characteristics was analysed using linear regression or logistic regression where appropriate. RESULTS The mean age of the OA patients was 56 years, 71% were female, and 61% had a Kellgren and Lawrence (K&L) score ≥ 2. The serum S100A8/A9 level did not differ between knee, hip, and hand OA patients and no association was found between serum S100A8/A9 and clinical characteristics. The serum S100A8/A9 level was negatively associated with the sum score of osteophytes after adjusting for sex and body mass index (BMI) [adjusted β -0.015, 95% confidence interval (CI) -0.030 to 0.001, p = 0.062] and positively associated with erythrocyte sedimentation rate (ESR) > 12 mm/h (adjusted OR 1.002, 95% CI 1.000-1.004 p = 0.049) for each increase in S100A8/A9 of 1 ng/mL. For hand OA patients, a negative association of S100A8/A9 with sum score of joint space narrowing was found (adjusted β -0.007, 95% CI -0.016 to 0.001, p = 0.099). CONCLUSIONS The results from this cross-sectional exploratory study do not support an important role for serum S100A8/A9 levels as a biomarker for clinical and structural characteristics in established knee, hip, and hand OA patients. The inverse association with structural abnormalities and the positive association with ESR may reflect inflammatory synovial processes in patients with OA before structural abnormalities occur.

Abstract
BACKGROUND Data on recent trends in mortality after hip fracture are scarce. Aims were therefore to examine secular trends in all-cause and cause-specific mortality post hip fracture and to compare this to the general population from 2000 to 2010. METHODS Population-based cohort study within the United Kingdom Clinical Practice Research Datalink and linked to cause of death data for 57.7% of patients. Patients with a first hip fracture (n=31,495) were matched to up to four controls by age, sex, index date, and practice. All subjects were followed for death, and lifestyle, disease and medication history adjusted hazard ratios (HRs) were calculated. RESULTS One-year all-cause mortality after hip fracture declined from 2009 and was 14% lower after, compared with before 2009 (22.3% to 20.5%, adj. HR 0.86, 95% CI: 0.81-0.92). The decline was observed for males (≥75years) and females (≥85years). Significant contributors to the decline in mortality post hip fracture were respiratory infections in females as were malignant diseases in males. However, one-year all-cause mortality remained unaltered over the decade when compared to controls with a 3.5-fold and 2.4-fold increased risk in males and females respectively. No significant changes were observed in the relative risks for one-year cause-specific mortality for both genders. CONCLUSIONS One-year mortality after hip fracture has declined over the last decade in the UK. However, the difference in one-year mortality between hip fracture patients and the general population remained unaltered. These observations highlight the need for the continued implementation of evidence-based standards for good hip fracture care.

Abstract
Background Infections are important denominators of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Pneumococcus pneumoniae has been identified as a relatively frequent cause of serious infections in SLE and vaccination against this pathogen is possible. We analysed the incidence of serious infections in a cohort of SLE patients, focussing on Streptococcus pneumoniae. Methods We retrospectively screened the medical records of all SLE patients who were regularly seen in the outpatient clinic of our department between January 2010 and December 2012. We registered all infections that necessitated admission to the hospital (serious infection) and compared relevant clinical and laboratory parameters and immunomodulating/immunosuppressive treatment in patients with and without serious infections. Results In the total cohort of 260 patients, there were 132 episodes of serious infection in 70 patients, with a median follow-up per patient of 11.4 years (range 0 to 50.2 years). S. pneumoniae accounted for 11/132 (8.3%) serious infection episodes and eight of 11 episodes were invasive. With a follow-up of 3970.6 years for the total cohort, this leads to an incidence of 201/100.000 patient-years. In the multivariate analysis neither clinical parameters nor use of immunosuppressive drugs correlated with occurrence of serious infections. Conclusions Compared to the incidence of invasive pneumococcal infections in the Dutch population (15.6/100.000 patient years), the incidence in SLE patients is 13 times higher. This, in combination with the absence of a relation to use of immunosuppressive drugs, is a strong argument to recommend vaccination against S. pneumoniae in all SLE patients.

Abstract
Self-reactive T cells have shown to have a potential role as regulators of the immune system preventing or even suppressing autoimmunity. One of the most abundant proteins that can be eluted from human HLA molecules is heat shock protein 70 (HSP70). The aims of the current study are to identify HSP70 epitopes based on published HLA elution studies and to investigate whether T cells from healthy individuals may respond to such self-epitopes. A literature search and subsequent in silico binding prediction based on theoretical MHC binding motifs resulted in the identification of seven HSP70 epitopes. PBMCs of healthy controls proliferated after incubation with two of the seven peptides (H167 and H290). Furthermore H161, H290, and H443 induced CD69 expression or production of cytokines IFNγ or TNFα in healthy controls. The identification of these naturally presented epitopes and the response they elicit in the normal immune system make them potential candidates to study during inflammatory conditions as well as in autoimmune diseases.

Abstract
OBJECTIVE During the past decades, a more cautious approach with respect to prescribing medication and physical exercise progressed toward evidence-based guidelines regarding the management of rheumatoid arthritis (RA). Currently, physical activity and other means to improve well-being and functioning are encouraged, and the disease is targeted earlier with more intensive and aggressive pharmacologic treatment. The current study examined whether psychological distress and physical disability in patients with RA reduced over the last 2 decades and whether this is explained by a reduction of disease activity. METHODS From 1990-2011, consecutive patients with RA (n = 1,151, age range 17-86 years, 68% female, 62% rheumatoid factor positive) were monitored at diagnosis and after 3-5 years of treatment (followup). Depressed mood, anxiety, and physical disability were predicted in multiple linear regression analyses by year of assessment, disease activity, and patient demographics. RESULTS Over the decades, depressed mood (P = 0.01), anxiety (P = 0.001), and physical disability (P = 0.02) reduced at diagnosis and within-treatment improvement of anxiety (P = 0.04) and physical disability (P < 0.001) increased. Percentages of patients with depressed mood, anxiety, and physical disability at followup changed from 25%, 23%, and 53%, respectively, 2 decades ago to 14%, 12%, and 31%, respectively, currently. After taking account of reduction in disease activity, the decrease in physical disability remained significant (P < 0.001). CONCLUSION Over the last 2 decades, psychological distress and physical disability decreased. This favorable trend might partly be due to reduced disease activity. The results indicate that patients with RA have a better opportunity to live a valued life currently than 20 years ago.

Abstract
OBJECTIVE To improve the management of hip or knee osteoarthritis (OA), a stepped care strategy (SCS) has been developed that presents the optimal sequence for care in three steps. This study evaluates the extent to which clinical practice is consistent with the strategy after implementation and identifies determinants of SCS-consistent care. DESIGN A 2-year observational prospective cohort study. SETTING General practices in the region of Nijmegen in the Netherlands. PARTICIPANTS Three hundred and thirteen patients with hip or knee OA and their general practitioner (GP). INTERVENTIONS Multifaceted interventions were developed to implement the strategy. MAIN OUTCOME MEASURES Consistency between clinical practice and the strategy was examined regarding three aspects of care: (i) timing of radiological assessment, (ii) sequence of non-surgical treatment options and (iii) making follow-up appointments. RESULTS Out of the 212 patients who reported to have had an X-ray, 92 (44%) received it in line with the SCS. The sequence of treatment was inconsistent with the SCS in 58% of the patients, which was mainly caused by the underuse of lifestyle advice and dietary therapy. In 57% of the consultations, the patient reported to have been advised to make a follow-up appointment. No determinants that influenced all three aspects of care were identified. CONCLUSIONS Consistency with the SCS was found in about half of the patients for each of the three aspects of care. Health care can be further optimized by encouraging GP s to use X-rays more appropriately and to make more use of lifestyle advice, dietary therapy and follow-up appointments.

Abstract
OBJECTIVES Health care and vocational professionals regularly encounter patients with rheumatic diseases who are embittered after a disability pension examination. People who are embittered typically feel victimised, experience resentment and injustice, resist help, and have difficulty coping. Our objective was to examine the occurrence of embitterment in patients with rheumatic diseases after a disability pension examination and the association of embitterment with its possible determinants helplessness and illness invalidation at work. METHODS The Illness Cognition Questionnaire (ICQ), Illness Invalidation Inventory (3*I), and Bern Embitterment Inventory were completed by patients who had 9 to 12 weeks earlier received the result of a disability pension examination. Diagnoses were fibromyalgia (n=103), rheumatoid arthritis (n=46), osteoarthritis (n=158), another rheumatic disease (n=62), and more than one rheumatic disease (n=187). Scores were compared to scores of reference groups. Hierarchical regression analyses were conducted. RESULTS Eighteen to 27 percent of patients had high levels of embitterment with no differences between diagnostic groups (p=0.71). Helplessness (p<0.001), the two invalidation dimensions discounting and lack of understanding (p<0.001), and the combination of helplessness with these invalidation dimensions (p<0.01), were predictive of more embitterment. CONCLUSIONS Our results suggest that, after a disability pension examination, embitterment is present in about one out of five patients with a rheumatic disease. This is problematic insofar as embitterment limits well-being, functioning, and the potential to reintegrate to work. To the extent that helplessness and invalidation at work are causal determinants of embitterment, interventions targeting these aspects may be key to reduce embitterment.

Abstract
OBJECTIVES Tocilizumab is effective in the treatment of rheumatoid arthritis (RA). A proportion of patients achieve low disease activity using a lower than registered starting dose. We investigated the feasibility of dose reduction to 4 mg/kg in patients who reached low disease activity at the registered dose of 8 mg/kg. METHODS In this retrospective study, data were collected of 22 patients successfully treated with tocilizumab 8 mg/kg for about 6 months and tapered to 4 mg/kg because of low disease activity. In case of loss of disease control, the dose could be increased again to 8 mg/kg. The percentage of patients with successful dose reduction and difference in DAS28 was described. RESULTS Mean DAS28 at time of dose reduction was 2.3 (SD 0.9). After 3 and 6 months follow-up, 77% (95% CI 54-91) and 55% (95% CI 32-76) of patients had successfully reduced the dose without losing disease control, respectively. DAS28 at 3 and 6 months was somewhat higher than baseline, 2.7 (SD 1.2) and 2.5 (SD 1.0) respectively. All patients who experienced worsening of disease activity after dose reduction regained low disease activity after dose escalation. CONCLUSIONS Dose reduction of tocilizumab seems feasible in a substantial proportion of patients. Dose escalation after flare was effective in all patients.

Abstract
OBJECTIVES To examine in patients with early rheumatoid arthritis (RA) whether quality of life (QoL), independently of disease activity, is affected by tight control treatment strategy schemes. METHODS In the Computer Assisted Management in Early RA (CAMERA) trials, patients with early RA, disease duration <1 year, no prior use of DMARDs) had been randomised to a methotrexate (MTX)-based tight control strategy or usual care (CAMERA study) or to 10 mg/d prednisone or placebo both added from start to a MTX-based tight control strategy (CAMERA-II study). In either study, randomisation to the more intensive strategy resulted in lower disease activity. To assess QoL, the 'Influence of Rheumatic Diseases on General Health and Lifestyle' questionnaire (IRGL) was used. Baseline and 1- and/or 2-year measurements were analysed with regression analyses with the IRGL (sub)scales as outcome variables and treatment strategy and disease activity assessing 28 joints (DAS28) as independent variables, correcting for baseline values of each scale and possible confounders (gender, age, rheumatoid factor status). RESULTS There was no clear association between either of the treatment strategies and QoL, but a decrease in DAS28 was associated with improvement in the majority of QoL (sub)scales. CONCLUSIONS No independent effect of the specific tight control strategies schemes on QoL was found, while there was a clear disease activity related effect. Thus frequent outpatient visits or the inclusion of prednisone in a tight control strategy did not negatively influence QoL.

Abstract
In this article, the 2010 European League against Rheumatism (EULAR) recommendations for the management of rheumatoid arthritis (RA) with synthetic and biological disease-modifying antirheumatic drugs (sDMARDs and bDMARDs, respectively) have been updated. The 2013 update has been developed by an international task force, which based its decisions mostly on evidence from three systematic literature reviews (one each on sDMARDs, including glucocorticoids, bDMARDs and safety aspects of DMARD therapy); treatment strategies were also covered by the searches. The evidence presented was discussed and summarised by the experts in the course of a consensus finding and voting process. Levels of evidence and grades of recommendations were derived and levels of agreement (strengths of recommendations) were determined. Fourteen recommendations were developed (instead of 15 in 2010). Some of the 2010 recommendations were deleted, and others were amended or split. The recommendations cover general aspects, such as attainment of remission or low disease activity using a treat-to-target approach, and the need for shared decision-making between rheumatologists and patients. The more specific items relate to starting DMARD therapy using a conventional sDMARD (csDMARD) strategy in combination with glucocorticoids, followed by the addition of a bDMARD or another csDMARD strategy (after stratification by presence or absence of adverse risk factors) if the treatment target is not reached within 6 months (or improvement not seen at 3 months). Tumour necrosis factor inhibitors (adalimumab, certolizumab pegol, etanercept, golimumab, infliximab, biosimilars), abatacept, tocilizumab and, under certain circumstances, rituximab are essentially considered to have similar efficacy and safety. If the first bDMARD strategy fails, any other bDMARD may be used. The recommendations also address tofacitinib as a targeted sDMARD (tsDMARD), which is recommended, where licensed, after use of at least one bDMARD. Biosimilars are also addressed. These recommendations are intended to inform rheumatologists, patients, national rheumatology societies and other stakeholders about EULAR's most recent consensus on the management of RA with sDMARDs, glucocorticoids and bDMARDs. They are based on evidence and expert opinion and intended to improve outcome in patients with RA.

Abstract
OBJECTIVES To identify factors hampering the level of physical activity in longstanding rheumatoid arthritis (RA) patients, and to evaluate the effects of glucocorticoid therapy on physical activity. METHODS Patient characteristics, disease characteristics and cardiovascular parameters were recorded in 170 patients, who participated in a study about glucose metabolism in longstanding RA treated with or without glucocorticoids. Disease activity scores (DAS28) were calculated and x-rays of hands and feet were taken and scored according to the Sharp van der Heijde score (SHS). Participants completed the health assessment questionnaire and short questionnaire to assess health-enhancing physical activity (SQUASH), which reflect physical disability and physical activity, respectively. Adherence rates to recommendations on physical activity were calculated, and patients were categorised as fully adhering, insufficiently adhering (adherence on less than the recommended number of days per week) or inactive (adherence on none of the days). RESULTS Forty-four percent of the patients showed adherence to the recommended minimum level of physical activity, and 22% were classified as inactive. Higher DAS28 and SHS, glucocorticoid therapy, and presence of cardiovascular risk factors were associated with lower total SQUASH physical activity scores univariately. In a multivariate model, higher age, higher body mass index (BMI), higher DAS28, and higher SHS negatively influenced the score significantly; cardiovascular risk factors and glucocorticoid therapy were no longer significantly influencing physical activity. CONCLUSIONS Physical activity in longstanding RA is hampered by higher age, higher BMI, higher disease activity, and more radiographic joint damage. Glucocorticoid therapy was not identified as independent risk factor in multivariate analyses.

Abstract
OBJECTIVE To evaluate the cost-effectiveness of personalised treatment for rheumatoid arthritis (RA) using clinical response and serum adalimumab levels. METHODS A personalised treatment algorithm defined, based on clinical (European League Against Rheumatism) response and drug levels at 6 months, whether adalimumab treatment should be continued in a specific dose or discontinued and/or switched to a next biological. Outcomes were simulated using a patient level Markov model, with 3 months cycles, based on a cohort of 272 adalimumab-treated patients with RA for 3 years and data of patients from the Utrecht Rheumatoid Arthritis Cohort. Costs, clinical effectiveness and quality adjusted life years (QALYs) were compared with outcomes as observed in usual care and incremental cost-effectiveness ratios were calculated. Analyses were performed probabilistically. RESULTS Clinical effectiveness was higher for the cohort simulated to receive personalised care compared with usual care; the average difference in QALYs was 3.84 (95 percentile range -8.39 to 16.20). Costs were saved on drugs: €2 314 354. Testing costs amounted to €10 872. Mean total savings were €2 561 648 (95 percentile range -3 252 529 to -1 898 087), resulting in an incremental cost-effectiveness ratio of €666 500 or €646 266 saved per QALY gained from a societal or healthcare perspective, respectively. In 72% of simulations personalised care saved costs and resulted in more QALYs, in 28% it was cost saving with lower QALYs. Scenario analyses showed cost saving along with QALYs gain or limited loss. CONCLUSIONS Tailoring biological treatment to individual patients with RA starting adalimumab using drug levels and short-term outcome is cost-effective. Results underscore the potential merit of personalised biological treatment in RA.

Abstract
OBJECTIVE To analyse the relation of joint damage on evolution of pain and physical functioning in two different cohorts of early phase of osteoarthritis (OA): Osteoarthritis Initiative (OAI) and Cohort Hip & Cohort Knee study (CHECK). METHODS Longitudinal data of 4-5 years follow-up (= medium term) of CHECK study and OAI were used. The Western Ontario and McMaster Universities of Osteoarthritis Index (WOMAC) was used to measure pain and physical functioning. For comparison with CHECK a subgroup of the OAI Incidence cohort was selected, Generalised estimating equations were used and all models were adjusted for gender, Body Mass Index, age, amount of working hours, racial background and hip pain at baseline. Finally, an interaction term was added to assess a possible differential effect of radiological progression on evolution of pain and function in the two cohorts. RESULTS At baseline, CHECK had less radiographic OA (K&L ≥2) compared with the OAI Incidence subgroup, but at follow-up CHECK had more radiographic change (51% vs 15% ≥1 K&L point increase; p<0.001). Over 4 years of follow-up, evolution of pain and physical functioning remained fairly stable in both cohorts, however, at different levels, OAI participants had less pain and less problems with physical functioning compared to CHECK participants. Both cohorts showed the same negative effect of rapid radiological change (K&L change of 2 points) on pain and physical function. CONCLUSIONS In participants with 'early symptomatic OA' rapid radiological change (change of ≥2 grades of K&L in 4 or 5 years) is related to worsening of pain and function.

Abstract
Over the last decade, increasing numbers of rheumatologists have incorporated musculoskeletal ultrasound (MSUS) as a valuable diagnostic tool into their clinical practice. Some countries have established training programmes for MSUS. The European League Against Rheumatism has developed education guidelines for the content and conductance of MSUS courses and it would be useful to standardise rheumatology MSUS training worldwide. A thorough knowledge of anatomy, US physics and technology, US scanning methods, US pattern of normal and pathological musculoskeletal tissues, definitions for US pathology, artefacts and pitfalls in both greyscale and Doppler modalities is necessary to perform efficient MSUS. MSUS training includes attending theoretical-practical and online courses, as well as studying textbooks and using digital video discs (DVDs). Having access to US equipment and performing supervised normal and pathological MSUS examinations for a training period are mandatory for consolidating MSUS learning. A proposal to accredit and certificate competence in MSUS is now being discussed.

Abstract
To develop recommendations for the management of medium to high-dose (ie, >7.5 mg but ≤100 mg prednisone equivalent daily) systemic glucocorticoid (GC) therapy in rheumatic diseases. A multidisciplinary EULAR task force was formed, including rheumatic patients. After discussing the results of a general initial search on risks of GC therapy, each participant contributed 10 propositions on key clinical topics concerning the safe use of medium to high-dose GCs. The final recommendations were selected via a Delphi consensus approach. A systematic literature search of PubMed, EMBASE and Cochrane Library was used to identify evidence concerning each of the propositions. The strength of recommendation was given according to research evidence, clinical expertise and patient preference. The 10 propositions regarded patient education and informing general practitioners, preventive measures for osteoporosis, optimal GC starting dosages, risk-benefit ratio of GC treatment, GC sparing therapy, screening for comorbidity, and monitoring for adverse effects. In general, evidence supporting the recommendations proved to be surprisingly weak. One of the recommendations was rejected, because of conflicting literature data. Nine final recommendations for the management of medium to high-dose systemic GC therapy in rheumatic diseases were selected and evaluated with their strengths of recommendations. Robust evidence was often lacking; a research agenda was created.
