Title: (1442–1487) SLE – Diagnosis, Manifestations, & Outcomes Poster II

Session Type: Poster Session B

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

Background/Purpose: Cognitive impairment (CI) is highly prevalent in patients with SLE [prevalence of 38% (range: 20%-80%)]. The exact mechanisms underlying CI is complex and multifactorial. Understanding the relationship between SLE CI phenotypes and analytes may be crucial for improving patient care and developing targeted interventions. We have previously defined two SLE CI subtypes (A and B) where subtype A performed worst on objective cognitive function compared with subtype B. Subtype A also, had greater levels of disease burden/damage, worse performance on subjective cognitive function, worse HRQoL and psychiatric measures compared with subtype B. We aimed to explore the associations between SLE CI phenotypes and serum analytes levels.

Methods: SLE patients aged 18-65 years attending a single lupus centre (January 2016 – October 2019) completed the ACR Neuropsychological Battery (ACR-NB) cognitive assessment. Age and gender matched normative data were used to obtain z-scores on all 19 tests of ACR-NB. The ACR-NB tests were reduced using principal component analysis (PCA). Similarity network fusion (SNF) was used to identify patient subtypes on the ACR-NB data, demographic and clinical variables, disease burden/activity, health related quality of life (HRQoL: SF-36, LupusQoL), the PDQ-20 (perceived cognitive deficits), Beck Depression Inventory-II, Beck Anxiety Inventory, and the fatigue severity scale (FSS) in addition to the serum levels of nine analytes (IL-6, IL-10, IFN-ɣ, MMP-9, NGAL/lipocalin, S100A8/A9, S100B, TNF-α, and TWEAK [determined by ELISA]). Differences between the SNF identified subtypes were evaluated using Kruskal-Wallis tests and chi-square tests.

Results: Of the 296 patients, 87% were female, mean age 41.5 ± 18.4 and mean disease duration 13.8 ± 10.1 years at study visit.The level of S100A8/A9, MMP-9, NGAL/lipocalin, and IL-6 were statistically significantly higher in the more severe SLE CI subtype A compared to B (Figure 1). No difference in the levels of IL-10, IFN-ɣ, S100B, TNF-α, and TWEAK were identified between SLE CI subtypes A and B.

Conclusion: This study demonstrated a higher level of serum analytes in association with the SLE CI subtypes identified with machine learning analysis. S100A8/A9, MMP-9, NGAL, and IL-6 levels were higher in the more severe subtype A where patients experience worse objective and and subjective cognitive function with a higher disease burden and damage compared with subtype B. The results of this study will further in deciphering the mechanisms of cognitive impairment in patients with SLE and the identification of targeted therapy.

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].
