Title: Rheumatoid Arthritis - Clinical Aspects VII: New Aspects of Monitoring Disease

Session Type: Abstract Submissions (ACR)

Background/Purpose

This study evaluated the association between baseline disease activity, as assessed with the multi-biomarker disease activity (MBDA) blood test, CRP or clinical measures, and the rate of radiographic progression over 2 years for patients with rheumatoid arthritis (RA) receiving stable therapy in the Brigham and Women’s Hospital Rheumatoid Arthritis Sequential Study (BRASS) Registry.

Methods

MBDA scores, CRP, DAS28-CRP, CDAI, RAPID3, and radiographic progression were analyzed at baseline (defined as the initial visit in the BRASS registry), for 143 patients with RA who had received a stable treatment, i.e., with no addition or removal of DMARDs and irrespective of dosing, over 2 years.  Radiographs of hands and wrists only, taken within 3 months of baseline in BRASS and 2 years later, were evaluated to determine the change per year in total Sharp score (DTSS).  Radiographic progression (RP) was defined as DTSS >3 per year over 2 years.  Predictive performance was assessed using AUROC.  Associations with RP were evaluated using univariate and multivariate logistic regression adjusted for potential confounders. 

Results

For 143 patients, mean age and disease duration were 59 and 18 years, respectively, with 84% female, 80% seropositive (RF+ and/or anti-CCP+), and 52% receiving MTX/non-biologic DMARD monotherapy, 19% a TNF inhibitor alone, 27% both in combination, and 2% not on any DMARD therapy. Mean baseline values were MBDA score=39, CRP=0.86 mg/dL, DAS28-CRP=4.1, CDAI=24.8, RAPID3=8.1 and TSS=68.  RP was observed in 18% (26/143) of patients. Better predictive accuracy for RP was observed for baseline MBDA score (AUROC=0.75), compared with baseline clinical CRP (AUROC=0.71), DAS28-CRP (AUROC=0.62), CDAI (AUROC=0.59) or RAPID3 (AUROC=0.50). Adjusting for BMI and baseline TSS, the significant independent predictors for RP were MBDA score (OR1SD=2.90, 95% CI=1.69-4.97), CRP (OR1SD=2.36, 95% CI=1.46-3.82), and DAS28-CRP (OR1SD=1.74, 95% CI=1.04-2.93), but not CDAI (OR1SD=1.46, 95% CI=0.89-2.41) and RAPID3 (OR1SD=0.97, 95% CI=0.61-1.55). For patients with low CRP (≤1 mg/dL) at baseline, RP was observed in 34.8% (8/23) with high MBDA score (>44) versus 8.1% (7/86) with low/moderate MBDA score (≤44) (p=0.003).

Conclusion

Baseline MBDA score was a better predictor of radiographic progression over 2 years than CRP, DAS28-CRP, CDAI or RAPID3 in patients with RA on stable therapy from the BRASS registry.

All abstracts accepted to ACR Convergence are under media embargo once the ACR has notified presenters of their abstract’s acceptance. They may be presented at other meetings or published as manuscripts after this time but should not be discussed in non-scholarly venues or outlets. The following embargo policies are strictly enforced by the ACR.

Accepted abstracts are made available to the public online in advance of the meeting and are published in a special online supplement of our scientific journal, Arthritis & Rheumatology. Information contained in those abstracts may not be released until the abstracts appear online. In an exception to the media embargo, academic institutions, private organizations, and companies with products whose value may be influenced by information contained in an abstract may issue a press release to coincide with the availability of an ACR abstract on the ACR website. However, the ACR continues to require that information that goes beyond that contained in the abstract (e.g., discussion of the abstract done as part of editorial news coverage) is under media embargo until 10:00 AM ET on November 14, 2024. Journalists with access to embargoed information cannot release articles or editorial news coverage before this time. Editorial news coverage is considered original articles/videos developed by employed journalists to report facts, commentary, and subject matter expert quotes in a narrative form using a variety of sources (e.g., research, announcements, press releases, events, etc.).

Violation of this policy may result in the abstract being withdrawn from the meeting and other measures deemed appropriate. Authors are responsible for notifying colleagues, institutions, communications firms, and all other stakeholders related to the development or promotion of the abstract about this policy. If you have questions about the ACR abstract embargo policy, please contact ACR abstracts staff at [email protected].
