Title: Systemic Sclerosis and Related Disorders – Clinical Poster II

Session Type: ACR Poster Session B

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

Background/Purpose:

Small vessel arteriopathy precedes the development of organ damage and tissue fibrosis in systemic sclerosis (SSc) and related disorders. It is currently considered that providing early vascular protection might result in a slower and milder progression of the disease. However, there is still no standard of care for this poorly understood process, besides symptomatic measures and treatment of complications. A major reason could be the lack of available tools for the routine assessment of the microcirculation at the clinic. In order to overcome this hurdle, we have launched a study addressing the utility of ultrasonography (US) in identifying robust outcome measures in patients with relevant SSc-like vasculopathy. Our first objective was to look for associations between US-based hemodynamic measures and features of vascular injury in a cohort of patients with Raynaud´s Phenomenon (RP).

Methods:

26 real-life patients have been enrolled, 10 of which had primary RP (PRP) and 16 secondary RP (SRP), with 11p diagnosed with SSc. 5 of the patients with SRP had a past history of complications, and 10 had macroscopic alterations at the time of the study. All patients had a recent nailfold videocapillaroscopy (NVC) recording which had been pathologic in 15p. Of these, 10p had an SSc typical NVC pattern of lesions. Patients underwent a Duplex US evaluation of 6 arterial regions (cubital, radial, 1st, 2nd, and 3rd digital branches and the superficial palmar arch) at the non-dominant hand. Systolic peak (PS), end diastolic velocity (ED), maximum speed, resistance index and the PS to ED ratio (PS/ED) were registered. Global and specific health questionnaires were recorded as independent variables, and their association with the US data was established with non-parametric tests. An alpha value of 5% was considered significant.

Results:

Globally, no single US parameter discriminated between PRP and SRP. However, patients with anti CENP-B antibodies, history of RP-associated complications, concurrent macroscopic alterations and/or an SSc-type of NVC pattern of lesions showed significantly lower PS and/or ED, at least at one region, in particular at the cubital artery and the 2nd digital branch, while a decreased PS/ED at the palmar arch was associated to CENP-B antibodies and to a past history of complications. Interestingly, the SF36 domain of global health was lower in the SRP subgroup (p 0.035) and associated to a lower PS/ED at the cubital artery (p 0.019). Also associated to this hemodynamic parameter were SF36 social performance (p 0.037) and mental health (p 0.04) domains, while both the RP severity scale and number of episodes were negatively associated with the cubital artery PS values (p 0.002, p 0.019, respectively).

Conclusion:

In this initial approach we have observed that Duplex US is able to distinguish patients with SSc-associated vasculopathy from those with milder RP. Our results point to reduced PS and PS/ED in the ulnar territory as potential outcome measures for further research.

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].
