Show moreBackground: We present a study protocol for a randomized, double-blind, placebo-controlled trial that investigates the hypothesis if intervention in the symptomatic phase preceding clinical arthritis (clinically suspect arthralgia (CSA)) is effective in preventing progression from subclinical inflammation to clinically apparent persistent arthritis. Currently, rheumatoid arthritis (RA) can be recognized and diagnosed when arthritis (joint swelling) has become detectable at physical examination. Importantly, at this time, the immune processes have already matured, chronicity is established, and patients require long-standing treatment with disease-modifying anti-rheumatic drugs. The TREAT EARLIER trial studies the hypothesis that intervention in the symptomatic phase preceding clinical arthritis is more often successful in permanent disease modification because of less matured underlying disease processes.Methods: A two-level definition to identify patients that are prone to develop RA is used. First, patients should have CSA and recent-onset arthralgia (< 1 year) that is suspect to progress to RA according to the expertise of the treating rheumatologist. Second, patients need to have subclinical inflammation of the hand or foot joints at 1.5 T MRI. The trial aims to recruit 230 participants from secondary care hospital settings across the south-west region of The Netherlands. Intervention will be randomly assigned and includes a single-dose of intramuscular 120 mg methylprednisolon followed by methotrexate (increasing dose to 25 mg/week orally) or placebo (both; injection and tablets) over the course of 1 year. Thereafter, participants are followed for another year. The primary endpoint is the development of clinically detectable arthritis, either fulfilling the 2010 criteria for RA or unclassified clinical arthritis of >= 2 joints, which persists for at least 2 weeks. DMARD-free status is a co-primary endpoint. The patient-reported outcomes functioning, along with workability and symptoms, are key secondary endpoints. Participants, caregivers (including those assessing the endpoints), and scientific staff are all blinded to the group assignment.Discussion: This proof-of-concept study is the logical consequence of pre-work on the identification of patients with CSA with MRI-detected subclinical joint inflammation. It will test the hypothesis whether intervention in patients in this early phase with the cornerstone treatment of classified RA (methotrexate) hampers the development of persistent RA and reduce the disease burden of RA.

Show moreObjective 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. Show less

Show moreObjectives To determine the relapse rate after discontinuing treatment in patients with rheumatoid arthritis ( RA) in sustained clinical remission, to identify predictors of a relapse and to evaluate treatment response after restarting treatment. Methods Five-year data from the BeSt study were used, in which 508 patients with recent-onset RA were randomised into four dynamic treatment strategies, aiming at a disease activity score (DAS) = <= 2.4. When DAS was < 1.6 for = <= 6 months, the last disease-modifying antirheumatic drug ( DMARD) was tapered and discontinued. If DAS increased to = 1.6, the last DMARD was immediately reintroduced. Results During a 5-year period, 115/508 patients (23%) achieved drug-free remission. Of these, 53 patients (46%) restarted treatment because the DAS was = 1.6 after a median of 5 months, 59 patients (51%) remained in drug-free remission for a median duration of 23 months and 3 (3%) were lost to follow-up. In those who restarted treatment, mean (SD) DAS increased from 1.13 (0.73) at remission before tapering to 2.18 (0.65) at restart, reflecting an increase in all four components of DAS. Multivariable predictors for restarting treatment were anti-cyclic citrullinated peptide (anti-CCP), last DMARD sulfasalazine, low baseline Health Assessment Questionnaire score and high mean DAS until remission. Of the 53 patients who restarted treatment, 39 (74%) again achieved remission 3-6 months after the restart. The median (IQR) damage progression in those who restarted treatment during the year of DAS increase was 0 (0-1) Sharp-van der Heijde units. Conclusion During 5 years DAS steered treatment, nearly 25% of patients with RA achieved drug-free remission; 46% restarted DMARD monotherapy because of a relapse, the majority of whom again achieved clinical remission within 3-6 months without showing radiological progression during the relapse.

Show moreIntroduction: To investigate whether accelerated hand bone mineral density (BMD) loss is associated with progressive joint damage in hands and feet in the first year of rheumatoid arthritis (RA) and whether it is an independent predictor of subsequent progressive total joint damage after 4 years. Methods: In 256 recent-onset RA patients, baseline and 1-year hand BMD was measured in metacarpals 2-4 by digital X-ray radiogrammetry. Joint damage in hands and feet were scored in random order according to the Sharp-van der Heijde method at baseline and yearly up to 4 years. Results: 68% of the patients had accelerated hand BMD loss (>-0.003 g/cm(2)) in the first year of RA. Hand BMD loss was associated with progressive joint damage after 1 year both in hands and feet with odds ratios (OR) (95% confidence intervals [CI]) of 5.3 (1.3-20.9) and 3.1 (1.0-9.7). In univariate analysis, hand BMD loss in the first year was a predictor of subsequent progressive total joint damage after 4 years with an OR (95% CI) of 3.1 (1.3-7.6). Multivariate analysis showed that only progressive joint damage in the first year and anti-citrullinated protein antibody positivity were independent predictors of long-term progressive joint damage. Conclusions: In the first year of RA, accelerated hand BMD loss is associated with progressive joint damage in both hands and feet. Hand BMD loss in the first year of recent-onset RA predicts subsequent progressive total joint damage, however not independent of progressive joint damage in the first year. Show less

Show moreObjective 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 <= 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. Show less
