Abstract
OBJECTIVE Remission in rheumatoid arthritis (RA) is an increasingly attainable goal, but there is no widely used definition of remission that is stringent but achievable and could be applied uniformly as an outcome measure in clinical trials. This work was undertaken to develop such a definition. METHODS A committee consisting of members of the American College of Rheumatology, the European League Against Rheumatism, and the Outcome Measures in Rheumatology Initiative met to guide the process and review prespecified analyses from RA clinical trials. The committee requested a stringent definition (little, if any, active disease) and decided to use core set measures including, as a minimum, joint counts and levels of an acute-phase reactant to define remission. Members were surveyed to select the level of each core set measure that would be consistent with remission. Candidate definitions of remission were tested, including those that constituted a number of individual measures of remission (Boolean approach) as well as definitions using disease activity indexes. To select a definition of remission, trial data were analyzed to examine the added contribution of patient-reported outcomes and the ability of candidate measures to predict later good radiographic and functional outcomes. RESULTS Survey results for the definition of remission suggested indexes at published thresholds and a count of core set measures, with each measure scored as 1 or less (e.g., tender and swollen joint counts, C-reactive protein [CRP] level, and global assessments on a 0-10 scale). Analyses suggested the need to include a patient-reported measure. Examination of 2-year followup data suggested that many candidate definitions performed comparably in terms of predicting later good radiographic and functional outcomes, although 28-joint Disease Activity Score-based measures of remission did not predict good radiographic outcomes as well as the other candidate definitions did. Given these and other considerations, we propose that a patient's RA can be defined as being in remission based on one of two definitions: (a) when scores on the tender joint count, swollen joint count, CRP (in mg/dl), and patient global assessment (0-10 scale) are all ≤ 1, or (b) when the score on the Simplified Disease Activity Index is ≤ 3.3. CONCLUSION We propose two new definitions of remission, both of which can be uniformly applied and widely used in RA clinical trials. We recommend that one of these be selected as an outcome measure in each trial and that the results on both be reported for each trial.

Abstract
Objectives. To determine whether molecular remission defined by a multi-biomarker disease activity (MBDA) score predicts a reduced risk of joint damage progression, and whether the MBDA score can augment existing classifications of remission. Methods. The study examined 271 visits for 163 RA patients in the Leiden Early Arthritis Cohort. The MBDA score and other variables from each visit were evaluated for prediction of progression [change in Sharp–van der Heijde Score (ΔSHS) >3] over the ensuing 12 months. Positive likelihood ratios (PLRs) for non-progression were calculated for remission based upon DAS based on 28-joint counts and CRP (DAS28-CRP <2.32), EULAR/ACR Boolean criteria and MBDA score (≤25). Results. Ninety-three per cent of patients in MBDA-defined remission did not experience progression, compared with 70% of patients not in MBDA remission (P = 0.001). There were no significant differences in the fraction of non-progressers between patients in remission and those not in remission using either DAS28-CRP or EULAR/ACR criteria. The PLR for non-progression over 12 months for MBDA remission was 4.73 (95% CI 1.67, 15.0). Among patients in DAS28-CRP remission, those with a high MBDA score were 2.3 times as likely (95% CI 1.1, 3.7) to have joint damage progression during the next year. Conclusion. MBDA-defined remission was an indicator of limited radiographic progression over the following 12 months. For patients in DAS28-CRP remission, high MBDA scores were a significant indicator of elevated risk of progression. MBDA results may provide a useful adjunct to clinical assessment to identify progression-free remission and assess subclinical disease.

Abstract
We analyzed the epidemiological changes of rheumatoid arthritis (RA) over three decades using patients from a single center in Singapore. All patients who fulfill the 1987 American College of Rheumatology criteria for RA were invited to enroll in a prospective disease registry. We analyzed the patient demographics, disease manifestation, management and patient-reported outcomes, including quality of life (QoL), in the three categories according to the year of disease onset: before 1989 (group I), 1990-1999 (group II) and after 2000 (group III). There were 1,153 patients with 231, 532 and 390 in groups I, II and III, respectively. The mean disease durations were 25, 12 and 4.8 years, respectively. The majority was female (84.1 %) and Chinese (76.6 %) with no socio-demographic differences across the three periods. The age of onset rises and the prevalence of rheumatoid factor falls with the proximity of disease onset. Patients with most recent disease onset had the earliest access to the rheumatologist. They also had the highest tender and swollen joint counts, lowest deformed joint count and highest remission rate. Patients in group I report better mental and emotional QoL though many developed marked disability. We have documented changes of the manifestations of RA that are dependent and independent of improved treatment. Significant differences in accessibility to the rheumatologist, RA activity, functional capacity, quality of life and comorbidities were seen in subsequent cohorts due to treatment evolution and more efficient healthcare delivery.

Abstract
Although treat-to-target goals for rheumatoid arthritis (RA) have been well-established through several guidelines in recent years, concerns regarding treat-to-prevent goals for RA remain unclear. RA patients are typically subjected to over- or under-treatment because it is difficult for clinicians to determine the prognosis of RA patients. This typically results in failure to select and identify patient subsets that should receive monotherapy or combination therapy to treat early RA. Understanding treat-to-prevent goals, as well as unfavorable prognoses, risk factors, and prediction methods for RA, is therefore critical for making treatment decisions. Rapid radiographic progression plays a central role in contributing to other composite RA indices, so this may be the best method for defining treat-to-prevent goals for RA. Accordingly, risk factors of rapid radiographic progression have been defined and two prediction models were retrospectively derived based on clinical trial data. Additional studies are required to develop risk models that can be used for accurate predictions.

Abstract
The development of evidence-based treat-to-target (T2T) recommendations alleviates decision-making for the rheumatologist and simultaneously promises substantial improvement of outcome for rheumatoid arthritis (RA) patients. For the office-based rheumatologist in Germany, however, implementation of T2T recommendations contains several difficulties. Limitations arise as a result of an insufficient number of rheumatologists as well as a lack of adequate remuneration both resulting in a lack of time for the individual RA patient. Furthermore budget limitations hinder the appropriate use of antirheumatic drugs and insofar counteract treating to the target of remission. Establishment of selective contracts for rheumatologists by health insurance funds might reduce many of these problems in future for the office-based rheumatologist in Germany.

Abstract
OBJECTIVES The provisional ACR/European League Against Rheumatism (EULAR) definition of remission in RA requires a score of ≤1 on the patient global assessment (PGA, 0-10 scale). We explored the relation between the PGA criterion and the patient's clinical disease state in an observational dataset. METHODS Data of 512 newly diagnosed RA patients of the Dutch Rheumatoid Arthritis Monitoring (DREAM) remission induction cohort were analysed. Both 28-joint counts and more comprehensive joint counts (tender joint count-53, swollen joint count-44) were used. RESULTS ACR/EULAR remission was present in 20.1% of the patients when using 28-joint counts and in 17.4% of the patients when applying more comprehensive joint counts. In 108 patients, the PGA score was >1 despite fulfilment of the remaining criteria (TJC28, SJC28 and CRP in mg/dl ≤1). Residual disease activity was observed in 31.5% (34/108) and median (interquartile range) scores on PGA, pain and fatigue were 2.4 (1.8-4.0), 2.0 (1.1-3.0) and 2.7 (1.3-5.0), respectively. Applying more comprehensive joint counts showed comparable results. In 19.5% (100/512) of patients, disease activity was absent (TJC53 = 0, SJC44 = 0, and CRP ≤1). In 41% (n = 41) of these patients, the PGA score was >1. Receiver operating characteristic analysis showed moderate accuracy of the PGA to discriminate between fulfilment and no fulfilment of all remaining criteria. CONCLUSION Frequently, patients did not meet the PGA criterion despite a good clinical disease state. Apparently the PGA is not solely influenced by RA disease activity. In patients with marked divergence between the PGA and objective clinical measurements, caution should be taken when applying the provisional ACR/EULAR definition of remission.

Abstract
Objective. To compare the effects of aggressive tight control therapy and conventional care on radiographic progression and disease activity in patients with early mild inflammatory arthritis. Methods. Patients with two to five swollen joints, Sharp–van der Heijde radiographic score (SHS) <5 and symptom duration ≤2 years were randomized between two strategies. Patients with a definite non-RA diagnosis were excluded. The protocol of the aggressive group aimed for remission (DAS < 1.6), with consecutive treatment steps: MTX, addition of adalimumab and combination therapy. The conventional care group followed a strategy with traditional DMARDs (no prednisone or biologics) without DAS-based guideline. Outcome measures after 2 years were SHS (primary), remission rate and HAQ score (secondary). Results. Eighty-two patients participated (60% ACPA positive). In the aggressive group (n = 42), 19 patients were treated with adalimumab. In the conventional care group (n = 40), 24 patients started with hydroxychloroquin (HCQ), 2 with sulfasalazine (SSZ) and 14 with MTX. After 2 years, the median SHS increase was 0 [interquartile range (IQR) 0–1.1] and 0.5 (IQR 0–2.5), remission rates were 66 and 49% and HAQ decreased with a mean of −0.09 (0.50) and −0.25 (0.59) in the aggressive and conventional care group, respectively. All comparisons were non-significant. Conclusion. In patients with early arthritis of two to five joints, both aggressive tight-control therapy including adalimumab and conventional therapy resulted in remission rates around 50%, low radiographic damage and excellent functional status after 2 years. However, full disease control including radiographic arrest in all patients remains an elusive target even in moderately active early arthritis. Trial registration.

Abstract
Objective To test the predictive ability of remission in terms of long-term disability in patients with recent-onset inflammatory polyarthritis (IP). Methods Consecutive patients with early IP, recruited between 1990 and 1994 (first cohort) and 2000 and 2004 (second cohort), were included in this study. Remission was defined as the absence of clinically detectable joint inflammation on a 51–joint count. In additional analyses, less stringent definitions of remission were used based on the 40– and 28–joint counts. Remission was assessed at 1, 2, and 3 years after inclusion. A 5-year Health Assessment Questionnaire score ≥1 (moderate disability) was chosen as the primary outcome measure. Results A total of 841 and 498 patients from the first and second cohorts, respectively, completed 5 years of followup. In the first cohort, patients with at least 1 episode of remission had lower odds of 5-year disability (odds ratio [OR] 0.26, 95% confidence interval [95% CI] 0.17–0.41). The number of times in remission correlated with the odds of disability, with a mean decrease in the probability of disability of ∼64% for each additional time point in remission (OR 0.38, 95% CI 0.28–0.52). The time until first remission was not associated with functional disability. Remission according to less stringent criteria showed a weaker protection against future disability. Similar results were found in the second cohort. Conclusion Patients with IP achieving a state of sustained remission early are less likely to show long-term deterioration of function compared with patients who do not achieve remission. The most persistent remission under the most stringent definition of remission has the lowest probability of long-term disability.

Abstract
Remission is the ideal treatment objective in the management of rheumatoid arthritis. To define remission, stringent criteria are needed which allow clinicians to assess the presence of active disease and which should be reliable enough to support therapeutic decisions. Currently there are many different remission classifications and none has been validated against important outcome measures such as the absence of progression of joint damage and disability. Recently, a subcommittee of the ACR and EULAR has proposed new criteria for remission based on a categorical classification and a composite score like SDAI allowing their use in clinical practice.

Abstract
Rheumatoid arthritis is characterised by persistent synovitis, systemic inflammation, and autoantibodies (particularly to rheumatoid factor and citrullinated peptide). 50% of the risk for development of rheumatoid arthritis is attributable to genetic factors. Smoking is the main environmental risk. In industrialised countries, rheumatoid arthritis affects 0·5-1·0% of adults, with 5-50 per 100 000 new cases annually. The disorder is most typical in women and elderly people. Uncontrolled active rheumatoid arthritis causes joint damage, disability, decreased quality of life, and cardiovascular and other comorbidities. Disease-modifying antirheumatic drugs (DMARDs), the key therapeutic agents, reduce synovitis and systemic inflammation and improve function. The leading DMARD is methotrexate, which can be combined with other drugs of this type. Biological agents are used when arthritis is uncontrolled or toxic effects arise with DMARDs. Tumour necrosis factor inhibitors were the first biological agents, followed by abatacept, rituximab, and tocilizumab. Infections and high costs restrict prescription of biological agents. Long-term remission induced by intensive, short-term treatment selected by biomarker profiles is the ultimate goal.
