OBJECTIVES To agree terminology and to develop recommendations for the diagnosis of calcium pyrophosphate deposition (CPPD). METHODS The European League Against Rheumatism (EULAR) CPPD Task Force, comprising 15 experts from 10 countries, agreed the terms and recommendations for diagnosis of CPPD using a Delphi consensus approach. Evidence was(More)
AIM To examine the test-retest reliability of the rheumatoid arthritis (RA) core disease activity measures and derived composite indices. METHODS A total of 28 stable patients with RA had 2 complete assessments within 1 week, which included the 7 RA core disease activity measures and derived disease activity indices (28-joint Disease Activity Score(More)
OBJECTIVE To identify if tobacco smoking or sociodemographic characteristics are risk factors of rheumatoid arthritis (RA). METHODS From a county RA register 361 patients in the age range 20-79 years were recruited from incidence cohorts with recent disease onset (mean 3.4 years) and compared with 5851 randomly selected individuals from the same(More)
OBJECTIVE Calprotectin is a major leucocyte protein, shown to correlate well with laboratory and clinical assessments in several inflammatory rheumatic diseases, and large concentrations of calprotectin have been found in synovial fluid from patients with rheumatoid arthritis (RA). The objective of the present study was to examine correlations between(More)
OBJECTIVE To explore the prevalence of work disability (WD) and to identify bio-psychological factors that predicts future WD in rheumatoid arthritis (RA) over a 7-year period. METHODS Patients were selected from the Oslo RA register. The prevalence of WD was studied cross-sectionally among respondents <67 years (n = 526) in a postal survey. Mean age (SD)(More)
OBJECTIVES To examine whether treatment with anti-tumour necrosis factor (TNF) alpha prevents loss of bone mineral density (BMD) at the spine and hip (generalised) and in the hands (local) of patients with rheumatoid arthritis, and to study the changes in markers of bone metabolism, including receptor activator of the NFkappaB ligand (RANKL) and(More)
OBJECTIVE To examine the incidence of rheumatoid arthritis (RA) in the community of Oslo, Norway; and to link the incidence to measures of disease severity. METHODS A register for RA in the county of Oslo was validated to be 85% complete for patients between 20 and 79 years of age. The incidence of RA was calculated from this register for patients with(More)
OBJECTIVE To investigate the relationship between hand bone mineral density (BMD) and radiographic joint damage, and between hand BMD and fractures in 50-70 year old women with longstanding RA. METHODS Demographic, clinical data, and imaging data on hand radiographs and Genants vertebral deformity score on spine radiographs were collected from 135 women(More)
OBJECTIVES To explore criteria regulating treatment with reimbursed biologic disease-modifying antirheumatic drugs (bDMARDs) in patients with rheumatoid arthritis (RA) across Europe and to relate criteria to indicators of national socioeconomic welfare. METHODS A cross-sectional study among 46 European countries. One expert from each country completed a(More)
OBJECTIVES Concurrent evaluation of data quality, internal consistency, test-retest reliability and validity of two patient-reported outcome measures (PROMs) for measuring functional impairment in hand OA (HOA); the Australian/Canadian Osteoarthritis Hand Index (AUSCAN; 15 items) and the Functional Index of HOA (FIHOA; 10 items). METHODS Patients from an(More)
