Title: Spondyloarthritis Including Psoriatic Arthritis – Diagnosis, Manifestations, & Outcomes Poster II: Extra-MSK & Comorbidities

Session Type: Poster Session C

Session Time: 9:00AM-11:00AM

Background/Purpose: Psoriatic arthritis (PsA) is an immune-mediated inflammatory arthritis associated with psoriasis that can cause remarkable joint damage (1). Subclinical cardiovascular disease (CVD) due to subclinical atherosclerosis is accelerated in PsA leading to overt cardiovascular events with increased mortality in those patients(2). Chronic inflammation plays a crucial role in the pathogenesis of atherosclerosis in PsA, together with the conventional risk factors (3). Intima-media thickness of the common carotid artery, evaluated by ultrasonography, is a good indicator of generalized atherosclerosis and coronary artery disease, giving early signs of subclinical atherosclerosis (4). We aimed to investigate the role of interleukin-1 beta (IL-1β), homeostatic model assessment of insulin resistance (HOMA-IR), and insulin level as early predictors of subclinical atherosclerosis in patients with PsA.

Methods: The study included 81 patients with PsA and 69 matched healthy volunteers. Serum IL-1β, HOMA-IR, and insulin levels were assessed. Ultrasonographic measurement of carotid intima-media thickness (CIMT) was done for both common carotid arteries and the mean CIMT was calculated.

Results: Our patients and controls were matched regarding age, sex, and body mass index (BMI) (P >0.05). Our study revealed a statistically significant difference between patients and controls regarding IL-1β, HOMA-IR, insulin level, and CIMT (p < 0.05) as illustrated in table (1). There was a statistically significant positive correlation between IL-1β, HOMA-IR, insulin level, and CIMT (p< 0.05), however, no significant correlation could be detected between ESR, CRP, and CIMT (p >0.05) as shown in table (2).

Conclusion: IL-1β, HOMA-IR, and insulin levels are correlated with CIMT in PsA. So, each of them can be used as a predictor of subclinical atherosclerosis in those patients. Consequently, IL-1β targeted therapy may have a pivotal role in the prevention of subclinical CVD in PsA.

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].
