  • Article: Patient-reported outcomes in a randomized trial comparing four different treatment strategies in recent-onset rheumatoid arthritis.
    [show abstract] [hide abstract]
    ABSTRACT: To investigate the effectiveness of 4 different treatment strategies for recent-onset rheumatoid arthritis (RA) on 2-year patient-reported outcomes, including functioning and quality of life. A total of 508 patients with recent-onset RA were randomly assigned to 1) sequential monotherapy, 2) step-up combination therapy, both starting with methotrexate, 3) initial combination therapy, including a tapered high-dose prednisone, or 4) initial combination therapy with methotrexate and infliximab. Treatment was adjusted every 3 months if the Disease Activity Score (DAS) remained >2.4. The McMaster Toronto Arthritis Patient Preference Disability Questionnaire, the Short Form 36 (SF-36), and scores for pain, global health, and disease activity measured on a 100-mm visual analog scale (VAS) were compared between groups at baseline and every 3 months thereafter for 2 years. After 2 years, all patient-reported outcomes had improved significantly from baseline, irrespective of the treatment strategy. SF-36 subscale scores approached population norms for 3 physical components, and achieved population norms (P > 0.05) for bodily pain and 4 mental components. Improvement in functioning, VAS scores, and physical items of the SF-36 occurred significantly earlier in patients treated with initial combination therapies (all comparisons after 3 months: overall P < 0.001; P < 0.05 for groups 1 and 2 versus groups 3 and 4). All 4 DAS-driven treatment strategies resulted in substantial improvements in functional ability, quality of life, and self-assessed VAS scores after 2 years. Initial combination therapy led to significantly faster improvement in all patient-reported measures.

  • Article: Progression of joint damage in early rheumatoid arthritis: association with HLA-DRB1, rheumatoid factor, and anti-citrullinated protein antibodies in relation to different treatment strategies.
    [show abstract] [hide abstract]
    ABSTRACT: To determine the association of HLA-DRB1, rheumatoid factor (RF), and anti-citrullinated protein antibody (ACPA) status with progression of joint damage in early rheumatoid arthritis (RA) treated according to different treatment strategies. The present study was conducted using data from the BeSt study (Behandelstrategieƫn voor Reumatoide Artritis [treatment strategies for rheumatoid arthritis]), a randomized trial comparing 4 targeted (toward achievement of a Disease Activity Score [DAS] of < or =2.4) treatment strategies: sequential monotherapy (group 1), step-up combination therapy (group 2), initial combination therapy with methotrexate, sulfasalazine, and prednisone (group 3), and initial combination therapy with methotrexate and infliximab (group 4), in 508 patients with early RA. Multivariate logistic regression analysis was used to predict progressive disease (increase of Sharp/van der Heijde score over 2 years beyond the smallest detectable change [4.6]) according to the presence or absence of the shared epitope (SE), DERAA, RF, and ACPA, with correction for other baseline characteristics. Progressive disease could not be predicted by presence of the SE: the odds ratio in groups 1, 2, 3, and 4, respectively, was 1.4, 2.6, 1.9, and 3.0. DERAA carriership did not protect against progressive disease (odds ratio 0.4, 1.4, 0.9, and 0.9 in groups 1, 2, 3, and 4, respectively). RF positivity and ACPA positivity predicted progressive disease in group 1 (odds ratio 4.7 [95% confidence interval 1.5-14.5] for RF and 12.6 [95% confidence interval 3.0-51.9] for ACPA), but not in groups 2-4 (for RF, odds ratio [95% confidence interval] 1.5 [0.5-4.9], 1.0 [0.3-3.3], and 1.4 [0.4-4.8] in group 2, group 3, and group 4, respectively; for ACPA, odds ratio [95% confidence interval] 3.4 [0.8-14.2], 1.7 [0.5-5.4], and 1.8 [0.5-6.8] in group 2, group 3, and group 4). In patients with early RA treated with the goal of tight control of the DAS, no significant association between HLA-DRB1 status and radiographic progression was found. RF and ACPA were predictive of progressive disease only in patients treated with sequential monotherapy. These observations suggest that effective treatment can prevent radiographic progression, even in patients with risk factors for severe damage.
