Abstract Objective To evaluate the efficacy of infliximab plus methotrexate (MTX) as induction therapy in patients with early rheumatoid arthritis (RA). Methods Disease‐modifying antirheumatic drug (DMARD)–naive active, RA who were included group 4 BeSt study initially treated (3 mg/kg) combination MTX (25 mg/week). The Disease Activity Score (DAS) was measured every 3 months. In persistent low disease activity (DAS ≤2.4) for at least 6 months, dosage tapered and finally discontinued; then...
Abstract Objective In classic studies on the genetic background of antibody production, major histocompatibility complex (MHC) has been shown to act as most prominent immune response gene that controls magnitude and specificity production. The strongest risk factor for rheumatoid arthritis (RA), human MHC HLA–DRB1 shared epitope (SE) alleles, predisposes antibodies against citrullinated proteins (ACPAs). ACPA levels are higher in SE‐positive patients with RA than SE‐negative RA. aim present...
To compare the clinical and radiological efficacy of initial vs delayed treatment with methotrexate (MTX) infliximab (IFX) in patients recent onset rheumatoid arthritis (RA).In a post hoc analysis BeSt study (for Behandel Stratagieen, Dutch for strategies), 117 who started MTX+IFX were compared 67 after failing (disease activity score (DAS)>2.4; median delay to IFX: 13 months) on > or =3 traditional DMARDs. If DAS remained >2.4, protocol dictated IFX dose increases 6, 7.5 10 mg/kg. In case <...
To determine the association of HLA-DRB1, rheumatoid factor (RF), and anti-citrullinated protein antibody (ACPA) status with progression joint damage in early arthritis (RA) treated according to different treatment strategies.The present study was conducted using data from BeSt (Behandelstrategieën voor Reumatoide Artritis [treatment strategies for arthritis]), a randomized trial comparing 4 targeted (toward achievement Disease Activity Score [DAS] < or =2.4) strategies: sequential...
Abstract Objective To evaluate societal costs and quality‐adjusted life years (QALYs) of treatment strategies for patients with recent‐onset active rheumatoid arthritis (RA). Methods Patients (n = 508) were randomly allocated to 1 4 strategy groups: sequential monotherapy, step‐up combination therapy, initial therapy prednisone, or infliximab. For 2 years, reported cost utility measures. Results Average QALYs (ideally 2.00) groups 1–4 1.29, 1.31, 1.32, 1.41, respectively, the British EuroQol...
