RESUMO
OBJECTIVE: The aim of this study was to investigate the effect of treat-to-target combination therapy with intensification at 13 weeks in early RA. METHODS: Early RA patients were classified as being at high or low risk of worsening RA based on disease activity and prognostic factors. High-risk patients received COBRA-light (prednisolone 30 mg/day tapered to 7.5 mg/day, MTX increasing to 25 mg/week), and low-risk patients received MTX monotherapy increasing to 25 mg/week. The primary outcome (target) was DAS44 < 1.6 or EULAR good response at 26 weeks. At 13 weeks, non-responders were randomized to (open-label) intensification [high-risk patients: prednisolone 60 mg/day tapered to 7.5 mg/day, addition of SSZ (2 g/day) and HCQ (400 mg/day); low-risk patients: prednisolone 30 mg/day tapered to 7.5 mg/day] or continuation. RESULTS: In the high-risk group (n = 150), 110 patients (73%) reached the target at 13 weeks, and 9 dropped out. Non-responders were randomized to intensification (n = 15) or continuation (n = 16), and after 26 weeks, 12 (80%) vs 7 (44%) of these, respectively, reached the target [difference: 36%, (95% CI 2%, 71%); P = 0.04]. In the low-risk group (n = 40), 17 (43%) reached the target. Non-responders were randomized to intensification (n = 8) or continuation (n = 7); 4 vs 3, respectively, reached the target.Adverse event rates were higher in the high-risk group, and higher in the intensification subgroup of that group. Serious adverse events were rare. Protocol violations were frequent and mostly led to mitigation of actual treatment intensification. CONCLUSION: Initial combination therapy was very successful in high-risk RA, and early intensification was beneficial in patients not reaching the strict target. The low-risk group was too small for drawing conclusions. In routine practice, adherence to early intensification based on strict targets is difficult.

Objective: To investigate the effect of TNF inhibitors (TNFis) on incidental and progressive hand OA in recent-onset RA patients after a 10 year follow-up. Methods: Radiographs of 262 RA patients (mean age 52 years, 66% women) from the BeSt study were scored for osteophytes in DIP/PIP joints using the Osteoarthritis Research Society International atlas (0-3; summed score 0-54) and according to the Kellgren-Lawrence (KL) score (0-4; summed score 0-72) at baseline and 10 year follow-up. TNFi treatment was assessed on visits every 3 months. Associations between TNFi treatment and hand OA were analysed on the patient and joint level using generalized linear models and generalized estimating equations, respectively. Results: Fifty-eight percent of the patients were treated with TNFi, with a median duration of 42 months. A total of 143 patients (55%) had hand OA in any IP joint at baseline based on the Osteoarthritis Research Society International osteophyte score. On the patient level, TNFi treatment duration did not affect incidental hand OA. However, every month of TNFi treatment resulted in a reduced relative risk (RR) of hand OA progression in DIP joints [relative risk (RR) 0.987 (95% CI 0.978, 0.996)] but not in PIP joints. On the joint level, the effect on hand OA progression was observed in DIP joints [RR 0.996 (95% CI 0.991, 1.000)] but not in PIP joints. The results from the KL score analyses were comparable to the osteophyte score. Conclusion: TNFi treatment was associated with a reduced risk on radiographic hand OA progression in DIP joints but not in PIP joints after 10 years. Although the effect sizes are small, these results provide evidence for influence of TNF-α in hand OA pathogenesis.

Objective: To assess the efficacy and safety of initial COBRA-light vs COBRA therapy in RA patients after a 4-year follow-up period. Methods: In the COBRA-light trial, 162 consecutive patients with recent-onset RA were randomized to either COBRA-light (prednisolone and MTX) or COBRA therapy (prednisolone, MTX and SSZ) for 1 year. After 1 year, treatment was continued without protocol, and adjusted by the treating physician according to clinical judgement, preferably with a treat-to-target strategy. Four years after trial initiation, all patients were invited to participate in the COBRA-light extension study, in which patients were interviewed and physically examined, patient reported outcomes were assessed, radiographs were made and clinical records were examined for comorbidities and medication use. Results: In the extension study, 149 out of 162 (92%) original trial patients participated: 72 COBRA-light and 77 COBRA patients. Initial COBRA-light and COBRA therapy showed similar effect on disease activity, physical functioning, radiological outcome and Boolean remission over the 4-year follow-up period. In addition, both treatment groups showed similar survival and major comorbidities, although the power to detect differences was limited. Besides protocolled differences in prednisolone, MTX and SSZ use, the use of other synthetic and biologic DMARDs and intra-articular and intramuscular glucocorticoid injections was similar in both treatment groups over the 4-year period. Conclusion: Early RA patients initially treated with COBRA-light or COBRA therapy had similar efficacy and safety outcomes over a 4-year follow-up period.

BACKGROUND: Treat-to-target therapy is effective for patients with rheumatoid arthritis (RA), but long-term results of continued targeted treatment are lacking. OBJECTIVE: To evaluate long-term outcomes in patients with early RA after 10 years of targeted treatment in 4 treatment strategies. DESIGN: Randomized trial. (Nederlands Trial Register: NTR262 and NTR265). SETTING: The Netherlands. PATIENTS: 508 patients with early active RA. INTERVENTION: Sequential monotherapy (strategy 1), step-up combination therapy (strategy 2), or initial combination therapy with prednisone (strategy 3) or with infliximab (strategy 4), all followed by targeted treatment aiming at low disease activity. MEASUREMENTS: Functional ability (Health Assessment Questionnaire [HAQ] score) and radiographic progression (Sharp-van der Heijde score) were primary end points. Survival in the study population was compared with the general population using the standardized mortality ratio. RESULTS: 195 of 508 of patients (38%) dropped out of the study (28% in strategy 4 vs. 40% to 45% in strategies 1 to 3, respectively). At year 10, mean HAQ score (SD) was 0.57 (0.56); 53% and 14% of patients were in remission and drug-free remission, respectively, without differences among the strategies. Over 10 years, mean HAQ scores were 0.69, 0.72, 0.64, and 0.58 in strategies 1 to 4, respectively (differences not clinically relevant). Radiographic damage was limited for all strategies, with mean Sharp-van der Heijde estimates during follow-up of 11, 8, 8, and 6 in strategies 1 to 4, respectively (P = 0.15). Standardized mortality ratio was 1.16 (95% CI, 0.92 to 1.46) based on 72 observed and 62 expected deaths, with similar survival among the 4 strategies (P = 0.81). LIMITATION: Dropout rate varied by strategy. CONCLUSION: In patients with early RA, initial (temporary) combination therapy results in faster clinical improvement and targeted treatment determines long-term outcomes. Drug-free remission, with prevention of functional deterioration and clinically relevant radiographic damage, and normalized survival are realistic outcomes.

OBJECTIVE: To investigate the effect of two different high-dose, step-down prednisolone regimens on body composition in early RA patients after 26 weeks of treatment. METHODS: Prednisolone-naive patients with recent-onset RA (n = 108) were randomized to either COBRA (prednisolone 60 mg/day, tapered to 7.5 mg/day in 6 weeks; MTX and SSZ) or COBRA-light therapy (prednisolone 30 mg/day, tapered to 7.5 mg/day in 8 weeks and MTX). Body composition was assessed at baseline (before or soon after start of treatment) and after 26 weeks with DXA, and recorded as total body mass (TBM), total fat mass (FM), total lean mass (LM) and trunk/peripheral fat ratio. Log-ratio analyses assessed the proportional distribution of TBM (between LM, FM and bone mass) and FM (between trunk, extremities and head). The subgroup of patients with a DXA before start of treatment (n = 38) was analysed separately. RESULTS: In the subgroup of patients with a DXA before start of treatment, TBM increased by 1.6 kg (P < 0.001) and total FM by 1.3 kg (P < 0.001). The trunk/peripheral fat ratio and the proportional distribution of TBM and FM remained stable over time. There were no differences between the treatment groups. Similar results were obtained in the study population as a whole. CONCLUSION: Both high-dose, step-down prednisolone regimens caused increases in TBM, mainly caused by an increase in FM, but we found no fat redistribution from peripheral to central tissues. This absence in fat redistribution contradicts the widely held assumption of rapid adverse effects of prednisolone on body composition in RA.

BACKGROUND: Recently, we documented the likely non-inferiority of Combinatietherapie Bij Reumatoïde Artritis (COBRA)-light therapy (methotrexate increased to 25â mg/week with initial prednisolone 30â mg/day) compared with the original COBRA therapy (methotrexate 7.5â mg/week, sulfasalazine 2â g/day, with initial prednisolone 60â mg/day) after 26â weeks in patients with early active rheumatoid arthritis (RA). OBJECTIVE: To assess the non-inferiority of COBRA-light versus COBRA after 1â year in terms of disease activity (DAS44), functional outcome (Health Assessment Questionnaire (HAQ)) and radiographic progression (Sharp/van der Heijde score (SHS)), and to assess the effect of adding etanercept. METHODS: An open-label, randomised controlled, non-inferiority trial of 162 patients with active early RA, following a treat-to-target protocol incorporating the addition of etanercept if DAS44 ≥1.6 at weeks 26 or 39. RESULTS: Both groups showed major improvements in DAS44 after 52â weeks: mean (SD) -2.41 (1.2) in the COBRA and -2.02 (1.0) in the COBRA-light group (p=ns). In both groups, functional ability improved and radiological progression of joints was minimal. At least one adverse event was reported in 96% of the patients in both groups. In total, 25 serious adverse events occurred: 9 vs 16 in COBRA and COBRA-light, respectively. Treatment actually instituted was often less intensive than required by the protocol: of the total population, 108 patients (67%) required etanercept (more in the COBRA-light group), but only 67 of these (62%) actually received it. CONCLUSIONS: Intensive COBRA or COBRA-light therapy has major, comparably favourable effects on disease activity, functional ability and radiological outcome after 1â year in patients with early RA. Protocolised addition of etanercept was often not implemented by treating rheumatologists, and patients receiving it appeared to have limited added benefit, probably because of low disease activity levels at its initiation.

BACKGROUND: Early, intensive treatment of rheumatoid arthritis (RA) with the combination of (initially high dose) prednisolone, methotrexate and sulfasalazine (COBRA therapy) considerably lowers disease activity and suppresses radiological progression, but is infrequently prescribed in daily practice. Attenuating the COBRA regimen might lessen concerns about side effects, but the efficacy of such strategies is unknown. OBJECTIVE: To compare the 'COBRA-light' strategy with only two drugs, comprising a lower dose of prednisolone (starting at 30 mg/day, tapered to 7.5 mg/day in 9 weeks) and methotrexate (escalated to 25 mg/week in 9 weeks) to COBRA therapy (prednisolone 60 mg/day, tapered to 7.5 mg/day in 6 weeks, methotrexate 7.5 mg/week and sulfasalazine 2 g/day). METHOD: An open, randomised controlled, non-inferiority trial in 164 patients with early active RA, all treated according to a treat to target strategy. RESULTS: At baseline patients had moderately active disease: mean (SD) 44-joint disease activity score (DAS44) 4.13 (0.81) for COBRA and 3.95 (0.9) for COBRA-light. After 6 months, DAS44 significantly decreased in both groups (-2.50 (1.21) for COBRA and -2.18 (1.10) for COBRA-light). The adjusted difference in DAS44 improvement between the groups, 0.21 (95% CI -0.11 to 0.53), was smaller than the predefined clinically relevant difference of 0.5. Minimal disease activity (DAS44 <1.6) was reached in almost half of patients in both groups (49% and 41% in COBRA and COBRA-light, respectively). CONCLUSIONS: At 6 months COBRA-light therapy is most likely non-inferior to COBRA therapy. CLINICAL TRIAL REGISTRATION NUMBER: 55552928.

OBJECTIVES: To investigate whether repair of erosions and joint space narrowing (JSN) in rheumatoid arthritis (RA) occurs and whether clinical variables predict this. METHODS: Eight-year follow-up data of the BeSt-study were used. Patients with recent onset RA (1987 criteria) were randomised to four treatment strategies and treated-to-target (Disease Activity Score (DAS)≤2.4). Yearly radiographs of hands and feet were scored in non-chronological order by four independent readers, using the Sharp/van der Heijde score (SHS). Damage repair was defined as a negative ΔSHS in an individual joint, seen by ≥3 out of 4 readers and persisting ≥2 consecutive years. Associations between repair and DAS, prednisone use, infliximab use, anticitrullinated protein antibody, gender, age, body mass index, symptom duration and randomisation arm were investigated with logistic regression analyses, corrected for mean SHS. RESULTS: Repair was seen in 17 patients (5.3%); 10 had regression of JSN, 7 of erosions, none had both. There were no significant associations in any of the regression analyses. CONCLUSION: After 8 years of treatment to target DAS≤2.4 in 508 patients with recent onset RA, repair of JSN and erosions was seen in 17/320 patients (5.3%). Probably due to the rarity of repair, we found no associations with suppression of disease activity or other predictors and repair.

OBJECTIVE: To determine the prevalence of large-joint damage and the association with small-joint damage in patients with RA after 8 years of low DAS (≤2.4)-targeted treatment with different treatment strategies. METHODS: Radiological data of 290 patients participating in the BeSt study, a randomized trial comparing initial monotherapy and initial combination therapy strategies, were used. Radiographs of large joints were scored using the Larsen score and of the small joints using the Sharp-van der Heijde score. With multivariate logistic regression analysis, an association between total damage of the small joints and of the large joints was investigated. RESULTS: After 8 years of treatment, damage was observed in 12% of shoulders, 10% of elbows, 26% of wrists, 13% of hips, 18% of knees and 7% of the ankles. Damage in one or more large joints was found in 64% of patients, with a median score of 1. No difference was found between initial monotherapy or combination therapy strategies. There was a significant association between damage progression in small joints and damage to one or more large joints (OR 1.02; 95% CI 1.00-1.04). CONCLUSION: After 8 years of DAS-targeted treatment in early RA patients, large-joint damage was found in 64% of patients and was associated with small-joint damage. Continued DAS-targeted treatment is probably more important in damage suppression than initial treatment strategy. Patients with more damage to hands and feet also have more damage to the large joints.

OBJECTIVES: To compare the prevalence of and predictors for sustained drug-free remission in two cohorts of patients with recent-onset RA treated with DAS-driven therapy or non-DAS-driven therapy. METHODS: Sustained drug-free remission was assessed after 5 years of follow-up in 508 patients treated with DAS-driven therapy (DAS ≤ 2.4) in a randomized treatment cohort, and in 424 patients who received non-DAS-driven therapy in a prospective inception cohort. The design of the DAS-driven cohort required systematic joint assessments with DAS-driven restart of therapy. Predictors for remission were identified by univariable and multivariable logistic regression in each cohort separately and in a combined multivariate logistic regression analysis corrected for propensity scores, including a sensitivity analysis on patients receiving initial monotherapy. RESULTS: Patients in the DAS-driven cohort had more active disease at baseline, but the prevalence of sustained drug-free remission was similar after DAS-driven (9.8%) and non-DAS-driven therapy (10.6%). Among patients with ACPA, drug-free remission was more frequently achieved after DAS-driven than after non-DAS-driven therapy (5.4 vs. 2.1%, OR = 2.68, 95% CI 0.97, 7.43). Absence of ACPA and short symptom duration were independent predictors for sustained drug-free remission in both cohorts. Initial treatment choice and inclusion period were not predictive. The sensitivity analysis yielded comparable results. CONCLUSION: Retrospectively comparing a DAS-driven to a non-DAS-driven therapy cohort, the occurrence and predictors of sustained drug-free remission were similar. The DAS-driven cohort had a more unfavourable prognosis. DAS-driven therapy may improve the chance of sustained drug-free remission in ACPA-positive patients with recent-onset RA.

OBJECTIVE: To compare clinical and radiological outcomes of four dynamic treatment strategies in recent-onset rheumatoid arthritis (RA) after 5 years follow-up. METHODS: 508 patients with recent-onset RA were randomly assigned into four treatment strategies: sequential monotherapy; step-up combination therapy; initial combination with prednisone; initial combination with infliximab. Treatment adjustments were made based on 3-monthly disease activity score (DAS) measurements (if DAS >2.4 next treatment step; if DAS ≤ 2.4 during ≥ 6 months taper to maintenance dose; if DAS <1.6 during ≥ 6 months stop antirheumatic treatment). Primary and secondary outcomes were functional ability, joint damage progression, health-related quality of life and (drug-free) remission percentages. RESULTS: After 5 years, 48% of patients were in clinical remission (DAS <1.6) and 14% in drug-free remission, irrespective of initial treatment. After an earlier improvement in functional ability and quality of life with initial combination therapy, from 1 year onwards clinical outcomes were comparable across the groups and stable during 5 years. The initial combination groups showed less joint damage in year 1. In years 2-5 annual progression was comparable across the groups. After 5 years, initial combination therapy resulted in significantly less joint damage progression, reflecting the earlier clinical response. CONCLUSION: Irrespective of initial treatment, an impressive improvement in clinical and radiological outcomes of RA patients can be achieved with dynamic treatment aimed at reducing disease activity, leading to 48% remission, 14% drug-free remission and sustained functional improvement. Starting with combination therapy resulted in earlier clinical improvement and less joint damage without more toxicity.

OBJECTIVE: To evaluate the effect of disease activity and antirheumatic treatment on blood pressure (BP) in patients with recent-onset rheumatoid arthritis (RA). METHODS: 508 patients with RA were randomised to receive (1) sequential monotherapy, (2) step-up combination therapy, (3) initial combination with prednisone or (4) with infliximab. Systolic and diastolic BP (SBP, DBP), disease activity score (DAS) and body mass index (BMI) were evaluated every 3 months. A linear mixed model was used to model SBP and DBP in each treatment group during year 1, adjusting for baseline BP, changes in BMI, DAS and cardiovascular medication. RESULTS: In all groups, mean SBP and DBP were lower for patients with DAS < or =2.4 than for patients with DAS >2.4. In addition, patients initially treated with infliximab (group 4) had a larger decrease in SBP and DBP over time than patients in groups 1-3. The decrease in BP was also observed in patients treated with infliximab after failure on conventional disease-modifying antirheumatic drugs in groups 1-3. The decrease in BP associated with treatment with infliximab occurred irrespective of the DAS response. CONCLUSION: A lower DAS is associated with lower BP. An additional decrease in BP was observed in patients treated with infliximab. Further research is needed to confirm the effect of infliximab on BP.

OBJECTIVES: The window of opportunity (WOO) hypothesis suggests a limited time frame to stop rheumatoid arthritis (RA). We hypothesised that a WOO could either be represented by a hyperbolic ('curved') decline in the chance to achieve the outcome sustained drug-free remission (sDFR) over time, after which achieving sDFR is not possible anymore, or by a more gradual linear decline approaching zero chance to achieve sDFR. METHODS: Patients with RA (symptom duration <2 years) were included from two randomised trials: BehandelStrategieën (BeSt), n=508 and Induction therapy with Methotrexate and Prednisone in Rheumatoid Or Very Early arthritic Disease (IMPROVED), n=479. Cox-regression was performed to assess the shape of the association between symptom duration and sDFR (Disease Activity Score<1.6, no disease-modifying anti-rheumatic drugs for ≥1 year) for patients starting slow-acting monotherapy (IMPROVED, BeSt) or fast-acting combination therapy (BeSt). Likelihood ratio tests were used to compare the fit of linear and non-linear models in both databases separately. Predictions from the best fitting models were used to assess whether the absolute risk to achieve sDFR approaches zero with increasing symptom duration. RESULTS: In BeSt and IMPROVED, 54/226 and 110/421 patients achieved sDFR with fast-acting treatment, and 53/243 (BeSt) with slow-acting treatment. Non-linear models did not fit better than linear models (fast-acting treatment BeSt p=0.743, IMPROVED p=0.337; slow-acting treatment BeSt p=0.609). After slow-acting monotherapy, linear models declined steeper. None of the models approached zero chance to achieve sDFR over time. CONCLUSIONS: The chance to achieve sDFR decreased gradually over time, and decreased fastest in patients starting slow-acting monotherapy. In both treatment groups, we found no evidence for a WOO within 2 years symptom duration.

PURPOSE OF REVIEW: To give an overview of recent strategy trials for the treatment of rheumatoid arthritis. RECENT FINDINGS: Strategy studies showed a clear benefit of dynamic result-driven treatment towards tight control of disease activity compared with 'usual care' in rheumatoid arthritis patients. In addition, treatment given after short symptom duration gives better outcomes than later initiation of treatment. In many trials, combination therapies, especially combinations with prednisolone or biologicals, were superior to monotherapies. Moreover, combination therapies were more effective if given early in the disease as compared with a delayed introduction, giving support to the window of opportunity hypothesis. In the BeSt study, initial combination therapy could be successfully discontinued in half of the patients, emphasizing that 'initial' would mean 'temporary'. Less evidence is available about initial combination in comparison with combination therapy with a shorter delay. Larger tight-controlled, goal-steered, dynamic strategy trials comparing initial combination therapy with a short-delay combination therapy will help to translate the use of initial (temporary) combination therapy into normal daily practice. SUMMARY: Treatment strategy trials have demonstrated that in the majority of patients with rheumatoid arthritis, the following approach is the most beneficial: goal-steered, dynamic treatment towards tight control of disease activity, including early introduction of (an) effective disease-modifying antirheumatic drug(s) in combination with prednisone or antitumor necrosis factor, which includes tapering of the medication if remission or low disease activity is achieved.

BACKGROUND: In patients with early rheumatoid arthritis, initial combination therapies provide earlier clinical improvement and less progression of joint damage after 1 year compared with initial monotherapies (as demonstrated in the BeSt study). OBJECTIVE: To evaluate whether the initial clinical and radiographic efficacy of combination therapies could be maintained during the second year of follow-up in patients with early rheumatoid arthritis. DESIGN: Randomized, controlled clinical trial with blinded assessors. SETTING: 18 peripheral and 2 university medical centers in the Netherlands. PATIENTS: 508 patients with early active rheumatoid arthritis. INTERVENTION: Sequential monotherapy (group 1), step-up combination therapy (group 2), initial combination therapy with tapered high-dose prednisone (group 3), or initial combination therapy with infliximab (group 4). Trimonthly treatment adjustments were made to achieve low disease activity. MEASUREMENTS: Primary end points were functional ability (Health Assessment Questionnaire) and Sharp-van der Heijde score for radiographic joint damage. RESULTS: Groups 3 and 4 had more rapid clinical improvement during the first year; all groups improved further to a mean functional ability score of 0.6 (overall, P = 0.257) and 42% were in remission (overall, P = 0.690) during the second year. Progression of joint damage remained better suppressed in groups 3 and 4 (median scores of 2.0, 2.0, 1.0, and 1.0 in groups 1, 2, 3, and 4, respectively [P = 0.004]). After 2 years, 33%, 31%, 36%, and 53% of patients in groups 1 through 4, respectively, were receiving single-drug therapy for initial treatment. There were no significant differences in toxicity. LIMITATIONS: Patients and physicians were aware of the allocated group, and the assessors were blinded. CONCLUSIONS: Currently available antirheumatic drugs can be highly effective in patients with early rheumatoid arthritis in a setting of tight disease control. Initial combination therapies seem to provide earlier clinical improvement and less progression of joint damage, but all treatment strategies eventually showed similar clinical improvements. In addition, combination therapy can be withdrawn successfully and less treatment adjustments are needed than with initial monotherapies.

OBJECTIVES: To compare outcomes of targeted treatment aimed at either low disease activity or remission in patients with early active rheumatoid arthritis (RA). METHODS: Five-year outcomes were compared in 133 patients with early active RA (1987), starting with methotrexate, sulfasalazine and tapered high dose of prednisone (arm 3 of the BehandelStrategieën (Treatment Strategies for Rheumatoid Arthritis) (BeSt) study), targeted at Disease Activity Score (DAS) ≤2.4 (low disease activity), and 175 patients with early RA, starting methotrexate and tapered high dose of prednisone, targeted at DAS <1.6 (selected from IMPROVED study who would have fulfilled inclusion criteria of the BeSt study). Association of treatment target with outcomes DAS <1.6, Boolean remission at year 1 and drug-free DAS remission (DFR) at year 5 were analysed by logistic regression analysis. RESULTS: At baseline, DAS <1.6 steered patients had a milder disease than DAS ≤2.4 steered patients (mean DAS 4.1±SD 0.7vs4.4±0.9, p=0.012) and less radiological damage. DAS decrease, functional ability and radiological damage progression over time were similar in both patient groups. DAS ≤2.4 was achieved in similar percentages in both patient groups, but more DAS <1.6 steered patients achieved DAS <1.6 and DFR. DAS <1.6 steered treatment was associated with achieving DAS <1.6 (OR 3.04 (95% CI 1.64 to 5.62)) and Boolean remission (3.03 (1.45 to 6.33)) at year 1 and DFR at year 5 (3.77 (1.51 to 9.43)). CONCLUSIONS: In patients with early active RA who start with comparable disease-modifying antirheumatic drug+prednisone combination therapy, subsequent DAS <1.6 steered treatment is associated with similar clinical and radiological outcomes over time as DAS ≤2.4 steered treatment; however, in the DAS <1.6 steered group, more patients achieved remission and drug-free remission.
RESUMO
OBJECTIVE: To investigate whether remission at single and consecutive visits predicts good outcome in early rheumatoid arthritis (RA). METHODS: The presence of remission according to American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) and other criteria (Boolean clinical, Clinical Disease Activity Index, Disease Activity Score [DAS], DAS in 28 joints, and Routine Assessment of Patient Index Data 3) was assessed in early RA patients during the first year of the Combination Therapy for Rheumatoid Arthritis light trial. Likelihood ratios were used to assess whether meeting the remission criteria at single visits (13, 26, 39, or 52 weeks) and consecutive visits (13 and 26, 26 and 39, or 39 and 52 weeks) predicted good outcome in the second year (52-104 weeks). Good outcome was defined for function (Health Assessment Questionnaire score consistently ≤0.5 and no deterioration), radiographic damage progression (no deterioration in Sharp/van der Heijde scores), and both ("overall good outcome"). RESULTS: Of the original 164 trial patients, 144 had evaluable data. In the second year, good functional outcome was observed in 35%, good radiographic outcome in 79%, and both in 28% of the patients. Almost all criteria predicted good functional and good overall outcome, at both single and consecutive visits; only single DAS remission did not significantly predict good overall outcome (P = 0.07). Sustained remission periods resulted in higher likelihood ratios than remission at single visits. None of the criteria predicted good radiographic outcome. CONCLUSION: Early RA patients who reached remission according to ACR/EULAR and other criteria during short or sustained periods were likely to retain good physical function in the subsequent months. Sustained remission periods were a stronger predictor than remission at single visits. However, in the setting of low overall damage progression, (sustained) remission was not predictive of good radiographic outcome.

OBJECTIVE: To evaluate if COmbinatie therapie Bij Reumatoïde Artritis (COBRA)-light therapy is cost-effective in treating patients with early rheumatoid arthritis (RA) compared with COBRA therapy. METHODS: This economic evaluation was performed next to the open-label, randomised non-inferiority COBRA-light trial in 164 patients with early RA. Non-responders to COBRA or COBRA-light received etanercept (50 mg/week) for 3-6 months. The societal perspective analysis took medical direct, non-medical direct and indirect costs into account. Costs were measured with patient cost diaries for the follow-up period of 52 weeks. Bootstrapping techniques estimated uncertainty around the cost-effectiveness ratios, presented in cost-effectiveness planes. RESULTS: 164 patients were randomised to either COBRA or COBRA-light strategy. At week 52, COBRA-light proved to be non-inferior to COBRA therapy on all clinical outcome measures. The results of the base-case cost-utility analysis (intention-to-treat analyses) revealed that COBRA-light strategy is more expensive (k9.3 (SD 0.9) compared with COBRA (k7.2 (SD 0.8)), but the difference in costs were not significant (k2.0; 95% CI -0.3 to 4.4). Also, both strategies produced similar quality-adjusted life-years (QALYs). The sensitivity analyses showed robustness of these results. In a per-protocol sensitivity analysis, in which costs of etanercept were assumed to be provided as prescribed according to protocol, both arms had much higher costs: COBRA-light: k11.5 (8.3) compared with k8.5 (6.8) for COBRA, and the difference in costs was significant (k2.9; 0.6 to 5.3). CONCLUSIONS: In the base-case cost-utility analysis, the two strategies produced similar QALYs for similar costs. But it is anticipated that if protocol had been followed correctly, the COBRA-light strategy would have been more costly due to additional etanercept costs, for a limited health gain. Given the limited added benefit and high costs of starting etanercept in the presence of low disease activity in our trial, such a strategy needs better justification than is available now.

RESUMO
OBJECTIVE: To investigate the longitudinal relationship between disease activity and self-reported physical activity (PA) in patients with early rheumatoid arthritis during the first year of treatment with combination therapy. METHODS: PA was measured with the Short Questionnaire to Assess Health-Enhancing Physical Activity at baseline, 13 weeks, 26 weeks, and 52 weeks after start of treatment in the context of the Combinatietherapie Bij Reumatoïde Artritis-Light trial. The reported PA classified patients as meeting or not meeting the World Health Organization (WHO) PA guideline (cutoff: 150 minutes of moderate-to-intense activity per week). Other measurements included the Disease Activity Score (DAS). Since both treatment arms showed equal treatment effect, these were analyzed as 1 group with simple before-after analyses and generalized estimating equations (GEE). RESULTS: In these analyses, 140 patients (86% of the trial population, 66% women, mean age 52 years) with complete data were included. At entry, 69% of the patients met the WHO PA guideline, increasing to 90% at week 13, and remaining stable at 89% after 1 year (P < 0.001). Mean DAS improved from 4.0 to 1.8 during the first year of treatment (P < 0.001). In GEE analyses, DAS decreases were significantly associated with PA increases (P = 0.008). Patients with clinically relevant responses (expressed as DAS remission, European League Against Rheumatism good response or American College of Rheumatology criteria for 70% improvement response) showed higher PA levels compared to nonresponders, regardless of the definition of response, for both the WHO and Dutch PA guideline. CONCLUSION: Early rheumatoid arthritis patients using combination therapy improved both disease activity and PA, a beneficial effect persisting for at least 1 year.

The objective of this study is to investigate if foot joint damage due to rheumatoid arthritis (RA) can predict whether patients will start wearing orthopaedic shoes (OS) within 10 years after treatment start. Data from recent onset RA patients with 10 years follow-up from the BeSt (Dutch acronym for treatment strategies) study were used. Treatment was tightly controlled, targeted at disease activity score (DAS) ≤2.4, according to 1 of 4 pre-specified treatment strategies. After 10 years of follow-up, orthopaedic shoe use was recorded in 285/508 patients (responders to questionnaires at 10 years). Between-group differences for orthopaedic shoe users and non-users were calculated at baseline, after 10 years, and change scores over the 10-year period were calculated. Predictors for orthopaedic shoe use were identified by univariable and multivariable logistic regression analyses. Orthopaedic shoe use was reported by 57/285 patients after 10 years. Orthopaedic shoe users had more joint damage, joint swelling and pain in the feet already at baseline and after 10 years. At both time points, DAS of orthopaedic shoe users and non-users was similar. Multivariable logistic regression showed that dichotomized foot erosions score (cut-off ≥1 erosion) (OR 2.42), anti-citrullinated protein antibodies (ACPA) (OR 4.64) and DAS (OR 1.77) were independent predictors of orthopaedic shoe use. Despite intensive targeted treatment, 57/285 recent onset RA patients started using orthopaedic shoes over 10 year of follow-up. Presence of foot erosions at treatment start predicts orthopaedic shoe use after 10 years. The risk of orthopedic shoe use increased for ACPA-positive patients and for those with higher baseline disease activity.
