OBJECTIVE: To study whether the Disease Activity Score (DAS) is a valid measure of disease activity in undifferentiated arthritis (UA). METHODS: Data from a randomized, double-blind, placebo-controlled trial of methotrexate (MTX) and placebo involving 110 patients with UA were used. Data included ba
BACKGROUND: There is a need for biomarkers that can predict anti-tumour necrosis factor (anti-TNF) treatment outcome in patients with rheumatoid arthritis (RA). Several studies have suggested that the rare A allele of the tumour necrosis factor alpha (TNFA) -308G-->A polymorphism could be associa
INTRODUCTION: Though remission is currently a treatment goal in patients with rheumatoid arthritis (RA), the number of patients who achieve and sustain remission in daily practice is still small. It is suggested that early remission will be associated with sustainability of remission. The aim was to
OBJECTIVES: Tight control studies including regular assessments of disease activity have shown that this approach has beneficial effects on disease activity, disability and joint damage in treating RA patients. Some of these studies included tight control with protocolized treatment, while others ap
BACKGROUND: Response shift theory suggests that improvements in health lead patients to change their internal standards and re-assess former health states as worse than initially rated when using retrospective ratings via the then-test. The predictions of response shift theory can be illustrated usi
OBJECTIVES: To assess the efficacy and safety of synthetic disease-modifying antirheumatic drugs (DMARDs) in adults with rheumatoid arthritis (RA)-a first step in a European League Against Rheumatism (EULAR) initiative to produce recommendations for the management of RA. METHODS: A systematic review
OBJECTIVE: Genome-wide association studies carried out in rheumatoid arthritis (RA) have led to the discovery of several genetic associations with this disease. Still, the current associated genetic variations can explain only part of the genetic risk involved in RA, and it is well recognized that t
