Organ Damage More Common in Early Stages of Lupus

TOPLINE:

The first year after the diagnosis of systemic lupus erythematosus (SLE) is crucial, with the highest percentage of patients experiencing organ damage. Cardiovascular issues are the second most prevalent after musculoskeletal damage in both early and later stages of SLE.

METHODOLOGY:

• Researchers assessed organ damage persisting at least 6 months over different stages of lupus in 4219 patients with SLE (mean age, 35.9 years; 89.6% women) from the Spanish Society of Rheumatology Lupus Registry.
• Damage was assessed using the Systemic Lupus International Collaborating Clinics/American College of Rheumatology Damage Index (SDI).
• Longitudinal analysis was conducted globally and by each SDI domain on 1274 patients with recorded damage event dates.
• Follow-up data were available out to 10 years in 1113 patients and to 20 years in 601.

TAKEAWAY:

• New damage was recorded in 20% of the patients with SLE within the first year after diagnosis, with the annual percentage of patients with new damage decreasing to 5% after the first 5 years of follow-up.
• In the first year, musculoskeletal damage was reported by the highest proportion of patients (21%), followed by cardiovascular damage inclusive of cerebrovascular accidents and claudication for 6 months (19%).
• The cardiovascular system remained the second most affected system even during the later stages of the diseases at years 10 and 20 of follow-up (20%-25%).
• Apart from musculoskeletal and cardiovascular damage, patients with lupus also showed renal and ocular damage in the early and later stages of the disease, respectively.

IN PRACTICE:

“Our study highlights the importance of cardiovascular damage and the need for its prevention during the earliest stages of the disease,” the authors wrote.

SOURCE:

The study was led by Irene Altabás-González, MD, PhD, Rheumatology Department, Vigo University Hospital Group, Vigo, Spain. It was published online on August 3, 2024, in Lupus Science & Medicine.

LIMITATIONS:

The retrospective collection of data in the study may have led to missing items; for example, the dates of damage events for the whole cohort were not available. 

DISCLOSURES:

The registry was supported by the Spanish Society of Rheumatology. No specific funding was received for the study. The authors declared no conflicts of interest.
