Systemic lupus erythematosus patients have a 5.6% risk of stroke, often within 5 years of diagnosis. Hypertension is a key risk factor, alongside antiphospholipid antibodies and Libman-Sacks endocarditis, contributing to cerebrovascular disease.

Area of Science:

  • Neurology
  • Rheumatology
  • Immunology

Background:

  • Systemic lupus erythematosus (SLE) is an autoimmune disease with diverse clinical manifestations.
  • Cerebrovascular disease is a known complication of SLE, but its specific characteristics require further investigation.

Observation:

  • A study of 234 SLE patients identified 13 (5.6%) with cerebrovascular events, including cerebral infarction, cerebral hemorrhage, and subarachnoid hemorrhage.
  • Stroke occurred within 5 years of SLE diagnosis in 54% of affected patients.
  • Hypertension was the most significant predisposing risk factor for stroke in this cohort.

Findings:

  • Lupus anticoagulant and anticardiolipin antibodies were prevalent in patients with cerebral infarction.
  • Renal involvement and high anti-deoxyribonucleic acid antibody titers were more common in SLE patients who experienced stroke.

  • Autopsy findings revealed small infarcts and hemorrhages, with Libman-Sacks endocarditis present in two patients with infarction, but no true angiitis.

    • Implications:

    • Hypertension, potentially mediated by immunologic abnormalities, is a critical factor in SLE-related stroke.
    • Antiphospholipid antibodies and Libman-Sacks endocarditis are strongly associated with occlusive cerebrovascular disease in SLE patients.
    • These findings highlight the need for vigilant cardiovascular risk management in SLE patients.
