Title: Imaging of Rheumatic Diseases Poster II

Session Type: Poster Session C

Session Time: 10:30AM-12:30PM

Background/Purpose: Radioisotopic synoviorthesis (RS) is an intra-articular local therapy that uses radioisotopes for the treatment of chronic recurrent synovitis with inadequate response to conventional therapy. Its effectiveness evaluated by ultrasound (US) has not been studied to date, and the factors associated with good US response are currently unknown. The aim of this study is to evaluate the effectiveness of RS evaluated by US, as well as to determine the factors associated with US response

Methods: Retrospective, observational study by reviewing the medical health records of all patients treated with RS at a tertiary rheumatology center from June 2019 to December 2023. Demographic, clinical, and analytical data were collected. The effectiveness of RS evaluated by US is performed according to usual clinical practice at one month and six months post-RS. US response at 6 months was defined as synovitis ≤1 according to the US Global OMERACT-EULAR Synovitis Score (GLOESS). Both groups were compared by univariable analysis.

Results: Out of a total of 34 patients, 32 patients completed the US evaluation and were included for analysis (mean age was 50.9 years, 62.5% were female, and mean disease duration was 6.6 years). A total of 14 patients (43.8%) showed US response to RS. Patients achieving US response had longer disease duration (10.3 vs 3.1; p=0.003), received more csDMARDs (84.6% vs 40%; p=0.016) and bDMARDs (69.2 vs 26.7%; p=0.024), and significantly had lower patient global assessment (5.8 vs 7.6; p=0.042) compared to non-responders. Baseline GLOESS score was not associated with US response at 6 months.

Conclusion: Less than half of the patients treated with RS showed US response at 6 months follow-up. Longer disease duration, higher use of csDMARDs and bDMARDs, as well as lower patient global assessment, are associated with US response.

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].
