Title: (2257–2325) SLE – Diagnosis, Manifestations, & Outcomes Poster III

Session Type: Poster Session C

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

Background/Purpose: The mortality in Systemic Lupus Erythematosus (SLE) varies largely across different countries most probably due to social, healthcare and ethnic differences. We need to identify demographic, clinical and serological predictors of mortality in SLE in our country, to improve the prognosis of SLE patients.
Objectives: To analyze the causes and identify predictive factors of mortality of SLE, and to assess the time evolution and chronological changes in Spain.

Methods: We performed a cross-sectional and retrospective study analyzing data from RELESSER cohort. Sociodemographic, clinical and serological variables, comorbidities and treatments, as well as indicators of disease activity, damage and severity were recorded. We excluded patients with lost information about the death variable and analyzed the differential features of deceased patients in comparisons with survivors through different time stages according to the date of diagnosis: until the 1980’s; the 1990’s and the first decade of the 21st century. Variables associated with mortality in univariate analysis were entered into different multivariate models to determine which ones were independently associated with the outcome of the disease in each decade.

Results: A total of 3665 patients were included, mostly caucasian female with similar general features regardless of the different time stages analyzed.18.4% until the 1980´s, the 5.97% in the 1990´s and up to 2.84% of the individuals in first decade of the 21st century, had died. The main age of death was similar in the different groups, around 55-58 years old (Table). The vascular events were the leading cause of death until the 1980´s, while in the last two decades, were infections.

The older age at diagnosis was predictor of mortality. Neither gender nor delay in diagnosis was independently associated with mortality, with the exception of the female sex, which behaved as a protective factor until the 1980´s.

The mortality predictors in our cohort were the presence of hypocomplementemia and organ damage until the 1980´s; thrombocytopenia, antiphospholipid syndrome and valve disease in the 1990´s; serositis, organ damage and depression in the first decade of the 21st century. Conversely, skin involvement was related to greater survival over the last two decades and comorbidities were associated with mortality in all periods of the study. The use of high doses of corticosteroids was predictor of mortality in each time stage, as well as the use of cyclophosphamide and rituximab from the year 2000. Antimalarial treatment was linked to improved survival in all the decades analyzed.

Conclusion: In the RELESSER cohort, the main cause of death in the last decades were infections. However, until the 1980´s, vascular events were predominant. Older age at diagnosis, use of corticosteroids and comorbidities were associated with significant increase in mortality in SLE, while antimalarial treatment was linked to improved survival. Data indicate that organ damage is a risk factor and skin involvement is a protective factor against mortality. Differentially, female sex until the 1980´s was independently associated with improved survival, and depression at the beginning of the 21st century was linked to mortality.

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].
