OBJECTIVE Osteoclast-associated receptor (OSCAR) is a newly identified osteoclast-specific receptor and is of key importance in the process of osteoclast costimulation. This study was undertaken to define the role of costimulation in osteoclast differentiation during inflammatory arthritis. METHODS OSCAR expression was assessed in the synovium and(More)
OBJECTIVE RA can be categorized into late-onset RA (LORA, >60-65 years) and young-onset RA (YORA, 30-55 years), depending on the patient's age at disease onset. Since the average age of the population is continuously increasing, LORA will most probably gain in importance in the future. Despite this growing importance, LORA has not been the focus of much(More)
OBJECTIVE To evaluate the baseline characteristics of patients with radiographic axial spondyloarthritis (SpA; ankylosing spondylitis [AS]) and patients with nonradiographic axial SpA, to investigate determinants of anti-tumor necrosis factor (anti-TNF) agent prescription on the background of a nonrestrictive reimbursement policy, and to assess the response(More)
Annexins are characterized by the ability to bind phospholipids of membranes in the presence of Ca2+. Annexin A5 represents a typical member of this protein family and is a natural occurring highly specific ligand for phosphatidylserine (PS). The exposure of PS is one major "eat me" signal for phagocytes of apoptotic and necrotic cells. Apoptotic cells are(More)
OBJECTIVE Osteocytes are considered to be sensors of bone damage and regulators of bone mass by specifically expressing sclerostin, an inhibitor of bone formation. The contribution of osteocytes in regulating local bone remodeling in arthritis is unknown. The aim of this study was to investigate the role of osteocytes as contributors to bone remodeling in(More)
TNF-alpha plays an important role in the natural history of rheumatoid arthritis (RA), a systemic disease characterized by endothelial activation and synovial involvement with bone erosions. Neuroendocrine signals contribute as well to RA, but their role is poorly understood. We measured in 104 RA patients and in an equal number of sex- and age-matched,(More)
OBJECTIVE To study the efficacy and safety of certolizumab pegol (CZP) in patients with active rheumatoid arthritis (RA) who had discontinued an initially effective TNF inhibitor (TNF-IR). METHODS A randomised 12-week double-blind trial with CZP (n=27) or placebo (n=10) followed by an open-label 12 week extension period with CZP. RESULTS Baseline(More)
New American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria for the classification of rheumatoid arthritis (RA) have recently been proposed. The aim of this cohort study was to examine whether fulfilling these 2010 ACR/EULAR criteria at the first visit has an impact on the clinical course and on the radiographic progression(More)
Biosimilars represent a new class of medicinal products that will have significant impact on clinical use. They are identical on an amino acid sequence level to existing reference biopharmaceutical products (originals). However, they may exhibit differences on a protein level. This paper provides a brief overview of biosimilar development and describes the(More)
