RESUMO
OBJECTIVES: With early and intensive treatment many patients with early RA attain remission. Aims were to investigate (1) the frequency and time to sustained remission and subsequent tapering in patients initially treated with conventional synthetic disease modifying anti-rheumatic drug ((cs)DMARD) strategies and (2) the frequency and time to flare and regained remission in patients tapering csDMARDs and biological (b)DMARDs during 2â years of follow-up. METHODS: Two-year follow-up data from the treatment in the Rotterdam Early Arthritis Cohort (tREACH) cohort were used. Patients were randomised to initial treatment with triple DMARD therapy (iTDT) with glucocorticoid (GC) bridging or methotrexate monotherapy (iMM) with GC bridging. Patients were evaluated every 3â months. In case Disease Activity Score (DAS) was >2.4 treatment was switched to a TNF-blocker. In case DAS<1.6 at 2 consecutive time points, tapering was initiated according to protocol. Outcomes were rates of sustained remission (DAS<1.6 at 2 consecutive time points), flare (medication increase after tapering) and remission after flare (DAS<1.6). Data were analysed using Kaplan-Meier analyses. RESULTS: During 2â years of follow-up, sustained remission was achieved at least once by 159 (57%) of patients, of whom 118 and 23 patients initiated tapering of csDMARDs and bDMARDs, respectively. Thirty-four patients achieved drug-free remission. Flare rates were 41% and 37% and within 1â year, respectively. After flare, 65% of patients tapering csDMARDs re-achieved remission within 6â months after treatment intensification. CONCLUSIONS: Regardless of initial treatment strategy, 57% of patients achieved sustained remission during 2â years of follow-up. Flare rates were 41% and 37% within 12â months in patients tapering csDMARDs and bDMARDs, respectively. TRIAL REGISTRATION NUMBER: ISRCTN26791028; Post-results.

OBJECTIVE: To evaluate rheumatologists' adherence to a low Disease Activity Score (DAS)-steered treat-to-target (T2T) strategy in treatment of patients with rheumatoid arthritis (RA) and to assess associated conditions. METHODS: Data of the BeSt study were used, a multicenter T2T strategy trial with 10-year followup. During 3 monthly visits, the physician answered questions about satisfaction with level of RA suppression, agreement with the study protocol, and agreement with the DAS. Associations between the answers and nonadherence were evaluated. RESULTS: Protocol adherence decreased over time from 100% to 60% per visit, with an average over time of 79%. Rheumatologists mostly agreed with the DAS (80-90% of visits over time) and were satisfied with the treatment steps (75-90%) and with the level of RA suppression (85-90%). The odds for protocol violation were higher when the rheumatologist disagreed with the DAS (odds ratio [OR] 2.3, 95% confidence interval [95% CI] 2.0-2.7 when they thought the DAS overestimated actual disease activity; OR 2.5, 95% CI 2.0-3.1 when they thought the DAS underestimated actual disease activity) or with the next required treatment step (OR 3.0, 95% CI 2.5-3.5), and when the physician was dissatisfied with disease suppression (OR 1.3, 95% CI 1.1-1.6). CONCLUSION: Rheumatologists generally agreed with and followed a 10-year followup DAS-steered T2T strategy. Disagreement with the DAS or the required treatment and dissatisfaction with the level of disease suppression were risk factors for nonadherence. These results indicate the feasibility of continued protocol-driven T2T therapy. For daily practice, adherence to T2T therapy might be improved by adopting the structure components of a clinical trial.

The aim of this study is to test the performance of a matrix model to predict rapid radiological progression (RRP) in a study population of early rheumatoid arthritis (RA) or undifferentiated arthritis (UA) patients. A matrix model using baseline CRP, erosion score, autoantibody status, and initial treatment choice to predict RRP (increase ≥5 points in Sharp-van der Heijde score (SHS) in 1 year) was derived from the BeSt study where patients with active RA (1987-criteria) were treated with initial monotherapy or combination therapy, aiming at low disease activity. In the IMPROVED study, patients with early RA (2010 criteria) and UA were initially treated with methotrexate and prednisone aiming at remission. A receiver operating characteristics (ROC) curve was used to assess the discriminative value of the model to predict damage progression in the IMPROVED population. Four hundred thirty-one out of 479 patients with RA and 106/122 with UA could be categorized as high, intermediate, low, or very low risk for RRP. One patient, with a very low risk profile, showed RRP. Thirty-two other patients (5 %) showed radiological progression ≥0.5 point SHS; none had a high risk profile and 22 had a very low risk profile. The area under the curve (AUC) of the ROC curve was 0.56 (95% CI 0.45; 0.68). A matrix model predicting RRP based on risk factors identified in recent onset active RA according to the 1987-criteria performed poorly in recent onset RA (2010 criteria) and UA. It appears that known risk factors for damage progression lose their impact with early remission steered treatment, so that RRP might be considered a phenomenon of the past.

AIM: To assess whether in early (rheumatoid) arthritis (RA) patients, metacarpal bone mineral density (BMD) loss after 4â months predicts radiological progression after 1â year of antirheumatic treatment. METHODS: Metacarpal BMD was measured 4 monthly during the first year by digital X-ray radiogrammetry (DXR-BMD) in patients participating in the IMPROVED study, a clinical trial in 610 patients with recent onset RA (2010 criteria) or undifferentiated arthritis, treated according to a remission (disease activity score<1.6) steered strategy. With Sharp/van der Heijde progression ≥0.5 points after 1â year (yes/no) as dependent variable, univariate and multivariate logistic regression analyses were performed. RESULTS: Of 428 patients with DXR-BMD results and progression scores available, 28 (7%) had radiological progression after 1â year. Independent predictors for radiological progression were presence of baseline erosions (OR (95% CI) 6.5 (1.7 to 25)) and early DXR-BMD loss (OR (95% CI) 1.5 (1.1 to 2.0)). In 366 (86%) patients without baseline erosions, early DXR-BMD loss was the only independent predictor of progression (OR (95% CI) 2.0 (1.4 to 2.9)). CONCLUSIONS: In early RA patients, metacarpal BMD loss after 4â months of treatment is an independent predictor of radiological progression after 1â year. In patients without baseline erosions, early metacarpal BMD loss is the main predictor of radiological progression.

OBJECTIVES: To assess which treatment strategy is most effective in inducing remission in early (rheumatoid) arthritis. METHODS: 610 patients with early rheumatoid arthritis (RA 2010 criteria) or undifferentiated arthritis (UA) started treatment with methotrexate (MTX) and a tapered high dose of prednisone. Patients in early remission (Disease Activity Score <1.6 after 4 months) tapered prednisone to zero and those with persistent remission after 8 months, tapered and stopped MTX. Patients not in early remission were randomised to receive either MTX plus hydroxychloroquine plus sulfasalazine plus low-dose prednisone (arm 1) or to MTX plus adalimumab (ADA) (arm 2). If remission was present after 8 months both arms tapered to MTX monotherapy; if not, arm 1 changed to MTX plus ADA and arm 2 increased the dose of ADA. Remission rates and functional and radiological outcomes were compared between arms and between patients with RA and those with UA. RESULTS: 375/610 (61%) patients achieved early remission. After 1 year 68% of those were in remission and 32% in drug-free remission. Of the randomised patients, 25% in arm 1 and 41% in arm 2 achieved remission at year 1 (p<0.01). Outcomes were comparable between patients with RA and those with UA. CONCLUSIONS: Initial MTX and prednisone resulted in early remission in 61% of patients with early (rheumatoid) arthritis. Of those, 68% were in remission and 32% were in drug-free remission after 1 year. In patients not in early remission, earlier introduction of ADA resulted in more remission at year 1 than first treating with disease-modifying antirheumatic drug combination therapy plus prednisone.

OBJECTIVE: To determine incidence of increased levels of alanine transferase (ALT) >2× upper limit of normal (ULN) in patients receiving methotrexate (MTX), treated according to a dynamic strategy, and to identify predictors of ALT of >2× ULN. METHODS: Data of 508 recent-onset rheumatoid arthritis (RA) patients from the BeSt study, randomized to initial monotherapy or combination therapy, were used. Treatment was dynamic, aiming at a disease activity score = ≤ 2.4. ALT was measured every three months. With logistic regression analyses, baseline variables predictive of first ALT of >2× ULN were identified and the association between use of concomitant antirheumatic drugs, the actual and cumulative dose of MTX and ALT of >2× ULN was determined. RESULTS: In total, 498 patients ever initiated MTX, with a total duration on MTX of 1,416 patient-years. In 89 patients, a first incidence of ALT of >2× ULN occurred. Incidence rate was 6.3 per 100 patient-years and cumulative incidence 18 %. ACPA positivity and baseline ALT of >1× ULN were independent predictors of later ALT of >2× ULN (OR 1.8 (95 % CI, 1.1-3.1) and OR 3.1 (95 % CI, 1.6-6.2), respectively). Smoking showed a trend (OR 1.6 (95 % CI, 0.98-2.7)). Mean MTX dosage over time was higher in patients with an ALT of >2× ULN. Patients who did not have an ALT of >2× ULN used more concomitant disease-modifying antirheumatic drugs and longer. CONCLUSIONS: In RA patients treated with MTX according to a dynamic strategy resembling daily clinical practice, incidence of increased ALT of >2× ULN was lower than previously reported, and also without treatment adjustments, persistence was rare. The recommendations for ALT monitoring may be reevaluated.

OBJECTIVES: To assess the relationship between joint tenderness, swelling and joint damage progression in individual joints and to evaluate the influence of treatment on these relationships. METHODS: First-year data of the Behandel Strategieën (BeSt) study were used, in which patients recently diagnosed as having rheumatoid arthritis (RA) were randomly assigned into four different treatment strategies. Baseline and 1-year x-rays of the hands and feet were assessed using the Sharp-van der Heijde score (SHS). With generalised estimating equations, 3-monthly assessments of tender and swollen joints of year 1 were related to erosion progression, joint space narrowing (JSN) progression and total SHS progression at the individual joint level (definition > 0.5 SHS units) in year 1, corrected for potential confounders and within-patient correlation for multiple joints per patient. RESULTS: During year 1, 59% of all 13 959 joints analysed were ever tender and 45% ever swollen, 2.1% showed erosion progression, 1.9% JSN progression and 3.6% SHS progression. Swelling and tenderness were both independently associated with erosion and JSN progression with comparable OR, although with higher OR in the hands than in the feet. Local swelling and tenderness were not associated with local damage progression in patients initially treated with infliximab. CONCLUSION: Clinical signs of synovitis are associated with erosion and JSN progression in individual joints after 1 year in RA. A disconnect between synovitis and joint damage progression was observed at joint level in patients who were treated with methotrexate and infliximab as initial treatment, confirming the disconnect between synovitis and the development of joint damage in tumour necrosis factor blockers seen at patient level.
