Modified disease activity scores that include twenty-eight-joint counts. Development and validation in a prospective longitudinal study of patients with rheumatoid arthritis.
The Modified DAS that included 28-joint counts were able to discriminate between high and low disease activity (as indicated by clinical decisions of rheumatologists) and are as valid as disease activity scores that include more comprehensive joint counts. Expand
Development and validation of the European League Against Rheumatism response criteria for rheumatoid arthritis. Comparison with the preliminary American College of Rheumatology and the World Health
EULAR response criteria showed better construct and discriminant validity than did the ACR and the WHO/ILAR response criteria for RA and the World Health Organization and International League Against Rheumatism criteria. Expand
Development of a disease activity score based on judgment in clinical practice by rheumatologists.
A disease activity score (DAS) was developed based on the clinical judgment of 6 rheumatologists consisting of the variables Ritchie articular index, number of swollen joints, erythrocyte sedimentation rate and general health measured on a visual analog scale. Expand
Judging disease activity in clinical practice in rheumatoid arthritis: first step in the development of a disease activity score.
An investigation of clinical and laboratory variables which might form the basis for judging disease activity in clinical practice was made by six rheumatologists in a prospective study of up toExpand
Validation of rheumatoid arthritis improvement criteria that include simplified joint counts.
OBJECTIVE To study the validity of response criteria for rheumatoid arthritis (RA) that included 28-joint counts instead of more comprehensive joint counts. METHODS In a double-blind,Expand
The prognostic value of anti-cyclic citrullinated peptide antibody in patients with recent-onset rheumatoid arthritis.
The data show that in almost 70% of RA patients, anti-CCP antibody is present at the early stages of disease, and patients with anti- CCP-positive patients developed significantly more severe radiologic damage than patients who were anti- CCP negative. Expand
The relationship between disease activity, joint destruction, and functional capacity over the course of rheumatoid arthritis.
In early RA, functional capacity is most associated with disease activity, and in late disease, with joint damage, which are the main factors explaining functional capacity. Expand
Remission in a prospective study of patients with rheumatoid arthritis. American Rheumatism Association preliminary remission criteria in relation to the disease activity score.
In a prospective follow-up study of patients with early-onset rheumatoid arthritis, the prevalence of remission according to the 1981 American Rheumatism Association (ARA) preliminary criteria was evaluated and the DAS was proposed as a tool to define remission. Expand
Assessment of outcome in ankylosing spondylitis: an extended radiographic scoring system.
The mSASSS is useful for assessing extensive radiographic damage in AS, it is reliable, detects changes over 48 weeks, and shows a satisfactory face and construct validity. Expand
Biannual radiographic assessments of hands and feet in a three-year prospective followup of patients with early rheumatoid arthritis.
The rate of progression in the first year was significantly higher than in the second and third years of study, indicating a flattening of the curve of radiographic progression of joint damage. Expand
