Methods: A prospective derivation cohort (n = 285) and validation cohort (n = 102) of RA patients receiving MTX were studied. Concentrations of plasma homocysteine, serum vitamin B12 , serum folate, erythrocyte vitamin B6 , and erythrocyte folate were determined at baseline and after 3 months of treatment.

Cardiovascular risk in rheumatoid arthritis: how to lower the risk?

Patients with rheumatoid arthritis (RA) carry an excess risk for cardiovascular disease, which is comparable to the risk in patients with type 2 diabetes mellitus. The mechanisms involved are partly related to traditional cardiovascular risk factors, disease-associated inflammation and undertreatment of traditional cardiovascular disease (CVD) risk factors. Since atherosclerosis is an inflammatory disease, the auto-immune mediated inflammation observed in RA patients contributes to increased endothelial dysfunction, oxidative stress and activation and vascular migration of leukocytes.

In vitro glucocorticoid sensitivity is associated with clinical glucocorticoid therapy outcome in rheumatoid arthritis.

Introduction: Genetic and disease-related factors give rise to a wide spectrum of glucocorticoid (GC) sensitivity in rheumatoid arthritis (RA). In clinical practice, GC treatment is not adapted to these differences in GC sensitivity. In vitro assessment of GC sensitivity before the start of therapy could allow more individualized GC therapy.

Methods: Data on disease activity states from all sustained visits were assessed from all patients who participate in the treatment in the Rotterdam Early Arthritis Cohort (tREACH) study, a stratified randomized trial to evaluate different treatment strategies in patients with a symptom duration of <1 year. Frequencies of treatment adaptations, based upon exclusive thresholds of various DAIs, were visualized in reclassification tables.

Diagnostic performance of the ACR/EULAR 2010 criteria for rheumatoid arthritis and two diagnostic algorithms in an early arthritis clinic (REACH).

Introduction: An ACR/EULAR task force released new criteria to classify rheumatoid arthritis at an early stage. This study evaluates the diagnostic performance of these criteria and algorithms by van der Helm and Visser in REACH.

Methods: Patients with symptoms ≤12 months from REACH were used.

Use of risk stratification to target therapies in patients with recent onset arthritis; design of a prospective randomized multicenter controlled trial.

Background: Early and intensive treatment is important to inducing remission and preventing joint damage in patients with rheumatoid arthritis. While intensive combination therapy (Disease Modifying Anti-rheumatic Drugs and/or biologicals) is the most effective, rheumatologists in daily clinical practice prefer to start with monotherapy methotrexate and bridging corticosteroids. Intensive treatment should be started as soon as the first symptoms manifest, but at this early stage, ACR criteria may not be fulfilled, and there is a danger of over-treatment.

Implementation of a physical activity intervention for people with rheumatoid arthritis: a case study.

Objectives: To investigate the potential facilitators and barriers regarding the implementation on a larger scale of an internet-based physical activity intervention which had previously proved to be effective in a randomized, controlled trial concerning sedentary patients with rheumatoid arthritis (RA).

Methods: Assuming a central delivery of the intervention by two trained physical therapists in four regions in the Netherlands, the following activities were employed: the recruitment of potential participants (RA patients), the acquisition of cooperation from referring rheumatologists and the acquisition of reimbursement from regional health insurance companies. Evaluation was done by means of the Reach, Evaluation, Adoption, Implementation and Maintenance framework, of which the following three dimensions were considered relevant: Reach (the number of potential participants), Adoption (readiness for adopting the programme in real life among rheumatologists) and Implementation (the extent to which the intervention could be delivered as intended).
