The association of treatment response and joint damage with ACPA-status in recent-onset RA: a subanalysis of the 8-year follow-up of the BeSt study.

چکیده
OBJECTIVE Anticitrullinated protein antibodies (ACPAs) are suggested to identify different subsets of patients with rheumatoid arthritis (RA). The authors compared the clinical and radiological responses to Disease Activity Score (DAS)-steered treatment in patients with RA positive or RA negative for ACPA. METHODS In the BehandelStrategieën (BeSt) study, 508 patients with recent-onset RA were randomised to four treatment strategies aimed at a DAS ≤2.4. Risks of damage progression and (drug-free) remission in 8 years were compared for ACPA-positive and ACPA-negative patients using logistic regression analysis. Functional ability and DAS components over time were compared using linear mixed models. RESULTS DAS reduction was achieved similarly in ACPA-positive and ACPA-negative patients in all treatment strategy groups, with a similar need to adjust treatment because of inadequate response. Functional ability and remission rates were not different for ACPA-positive and ACPA-negative patients. ACPA-positive patients had more radiological damage progression, especially after initial monotherapy. They had a lower chance of achieving (persistent) drug-free remission. CONCLUSION Clinical response to treatment was similar in ACPA-positive and ACPA-negative patients. However, more ACPA-positive patients, especially those treated with initial monotherapy, had significant radiological damage progression, indicating that methotrexate monotherapy and DAS- (≤2.4) steered treatment might be insufficient to adequately suppress joint damage progression in these patients.

Plasma levels of leptin and visfatin in rheumatoid arthritis patients; is there any relationship with joint damage?
Objective (s):Rheumatoid arthritis (RA) is a chronic systemic inflammatory disorder, primarily targeting the synovium and articular cartilage that leads to joint damage. Recent reports have suggested the role of adipocytokines in mediating joint damage; however it still is a matter of debate. The purpose of this study was to evaluate the association between serum values of adiopocytokines (lept...
متن کاملDistinct ACPA fine specificities, formed under the influence of HLA shared epitope alleles, have no effect on radiographic joint damage in rheumatoid arthritis.
OBJECTIVES Human leucocyte antigen shared epitope (SE) alleles are associated with joint destruction, the presence of anticitrullinated protein antibodies (ACPA) and the ACPA fine specificity repertoire in rheumatoid arthritis (RA). A large variation in joint destruction is seen within the ACPA-positive patient population, and it is conceivable that certain ACPA reactivities contribute to radio...
متن کاملBone mineral density loss in postmenopausal onset rheumatoid arthritis is not greater than premenopausal onset disease
Background: Postmenopausal onset rheumatoid arthritis (post-RA) is expected to have greater bone mineral density (BMD) loss than premenopauasal onset (pre-RA) due to estrogen deficiency and aging. This study aimed to compare the BMD status of the two RA groups with age-matched non-RA controls. Methods: The patients with RA on follow-up examination were stratified according to age of onset. ...
