Title: Rheumatoid Arthritis – Treatments Poster II: PROs, Safety and Comorbidity

Session Type: ACR Poster Session B

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

Background/Purpose: Leptin is an adipokine that plays an important role in the regulation of body weight and also participates in immune homeostasis and inflammatory processes1,2. Chronic systemic inflammation is of major importance in the development of atherosclerosis in rheumatoid arthritis (RA)3. IL-6 blocker yields a rapid improvement of endothelial function4. Therefore, the aim of this study was to determine whether the infusion of IL-6 blockade improves the endothelial function by altering circulating leptin concentrations in patients with RA.

Methods: 50 Spanish patients on treatment with anti-IL-6 monoclonal antibody-Tocilizumab who fulfilled the 2010 classification criteria for RA5 were recruited. Patients with diabetes mellitus or plasma glucose >110 mg/dl were excluded. Leptin serum levels were determined immediately prior to (time 0) and after (time 60 minutes) Tocilizumab infusion by ELISA.

Results: A significant reduction in leptin concentration was observed following Tocilizumab infusion (mean ± standard deviation (SD): 9.24 ± 7.98 ng/ml versus 7.91 ± 7.36 ng/ml, p˂0.0011). In addition, a significant positive correlation between leptin concentration and insulin resistance (HOMA at the time of the study) was found (r=0.40; p=0.0046). Furthermore, a significant negative correlation between leptin levels and insulin sensitivity (QUICKI) was disclosed (r= -0.46; p=0.0009).

Conclusion: Our study confirms that circulating leptin concentrations are modulated by anti-IL-6 treatment. In addition, leptin concentration correlates with insulin resistance and sensitivity. The beneficial effect of anti-IL-6 blockage on cardiovascular mortality in RA may be mediated by reduction in serum levels of leptin.

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].
