STATEMENT OF FINDINGS: An inception cohort of 238 patients having peripheral joint synovitis of less than 12 months duration was evaluated clinically and followed prospectively for 1 year to determine the clinical significance of a number of rheumatoid arthritis (RA) associated autoantibodies. Serum samples collected at the time of the initial evaluation(More)
We have investigated hepatic de novo lipogenesis and the ratio of apoB-48/apoB-100 during chronic carbohydrate supplementation with or without administration of exogenous insulin in rats. Two groups received chronic (2 weeks) carbohydrate supplementation either as 10% glucose or 10% fructose (wt/v) in their drinking water. Two other groups received(More)
OBJECTIVE To investigate the production of cytokines by T cells in patients with rheumatoid arthritis (RA), reactive arthritis (REA) and osteoarthritis (OA). METHODS The lymphokines interleukin (IL)-2, IL-4, interferon gamma (IFN-gamma) and tumour necrosis factor beta (TNF-beta), as well as the monokines IL-1, IL-6 and TNF-alpha, were measured by(More)
Autoantibodies are proven useful diagnostic tools for a variety of rheumatic and non-rheumatic autoimmune disorders. However, a highly specific marker autoantibody for rheumatoid arthritis (RA) has not yet been determined. The presence of rheumatoid factors is currently used as a marker for RA. However, rheumatoid factors have modest specificity (~70%) for(More)
BACKGROUND To facilitate the development of therapies for rheumatoid arthritis (RA), the Innovative Medicines Initiative BTCure has combined the experience from several laboratories worldwide to establish a series of protocols for different animal models of arthritis that reflect the pathogenesis of RA. Here, we describe chronic pristane-induced arthritis(More)
INTRODUCTION Pristane-induced arthritis (PIA) in the rat has been described as an animal model of inflammatory arthritis which exhibits features similar to rheumatoid arthritis in humans, such as a chronic, destructive, and symmetrical involvement of peripheral joints. However, so far little is known about the earliest inflammatory events and their(More)
Chronic inflammation is a major trigger of local and systemic bone loss. Disintegration of cell-matrix interaction is a prerequisite for the invasion of inflammatory tissue into bone. CD44 is a type I transmembrane glycoprotein that connects a variety of extracellular matrix proteins to the cell surface. Tumor necrosis factor (TNF) is a major inducer of(More)
Rheumatoid arthritis is a heterogeneous disease with respect to clinical manifestations, serologic abnormalities, joint damage and functional impairment. Predicting outcome in a reliable way to allow for strategic therapeutic decision-making as well as for prediction of the response to the various therapeutic modalities available today, especially(More)
BACKGROUND Self-reported outcome instruments in health research have become increasingly important over the last decades. Occupational therapy interventions often focus on occupational balance. However, instruments to measure occupational balance are scarce. The aim of the study was therefore to develop a generic self-reported outcome instrument to assess(More)
