Objective—The study aims to examine the threshold in disease activity associated with switching biologic treatment regimens in RA patients in real-world clinical practice. Methods—Using data from a prospective observational North American cohort of RA patients through 12/30/2009, patients who initiated a new anti-TNF agent with ≥ 6 months of follow-up were identified. Patients were classified as switchers or maintainers depending on whether they continued their anti-TNF treatment or switched (including discontinuation) within 12 months. Level of disease activity measured by CDAI and DAS28 at time of switch (corresponding follow-up visit for maintainers) was examined and random effect multivariable logistic regression was used to adjust for covariates. Results—Mean age and RA duration among 1,549 eligible patients were 56.1 and 9.6 years, 80 % were women, 62 % were initiating their 1st biologic and 30 % 2nd. At time of switch, the median DAS28 and CDAI were 3.1 and 8.4 among maintainers, and 4.0 and 15.2 among switchers. Maintainers also experienced a greater amount of reduction in disease activity compared with switchers (CDAI: −7.7 vs. −2.3; DAS28: −1.1 vs. −0.3). The threshold to switch

Background: Methotrexate (MTX) is an agent used in chemotherapy of tumors and autoimmune disease including rheumatoid arthritis (RA). In addition, MTX has some anti-inflammatory activity. Although dihydrofolate reductase (DHFR) is a well-known target for the anti-tumor effect of MTX, the mode of action for the anti-inflammatory activity of MTX is not fully understood. Methodology/Result: Here, we performed a screening of MTX-binding proteins using T7 phage display with a synthetic biotinylated MTX derivative. We then characterized the interactions using surface plasmon resonance (SPR) analysis and electrophoretic mobility shift assay (EMSA). Using a T7 phage display screen, we identified T7 phages that displayed part of high-mobility group box 1 (HMGB1) protein (K86-V175). Binding affinities as well as likely binding sites were characterized using genetically engineered truncated versions of HMGB1 protein (Al G1-K87, Bj: F88-K181), indicating that MTX binds to HMGB1 via two independent sites with a dissociation constants (KD) of 0.5060.03 mM for Al and 0.2460.01 mM for Bj. Although MTX did not inhibit the binding of HMGB1 to DNA via these domains, HMGB1/RAGE association was impeded in the presence of MTX. These data suggested that binding of MTX to part of the RAGE-binding region (K149-V175) in HMGB1 might be significant for the anti-inflammatory effect of MTX. Indeed, in murine macrophage-like cells (RAW 264.7), TNF-a release and mitogenic activity elicited by specific RAGE stimulation with a truncated monomeric HMGB1 were inhibited in

Introduction: Rheumatoid arthritis (RA) is a systemic, chronic inflammatory disease influenced by both genetic and environmental factors, leading to joint destruction and functional impairment. Recently, a large-scaled GWAS meta-analysis using more than 37,000 Japanese samples were conducted and 13 RA susceptibility loci were identified. However, it is not clear whether these loci have significant impact on joint destruction or not. This is the first study focused on the 13 loci to investigate independent genetic risk factors for radiographic progression in the first five years from onset of RA.
