Abstract

Insights

Cerebral MRI findings in systemic lupus erythematosus (SLE) patients with antiphospholipid syndrome (APLS) showed similar gross brain changes. However, strokes and leukoaraiosis were more prevalent in APLS patients, suggesting a prothrombotic state.

Area of Science:

  • Neurology
  • Radiology
  • Rheumatology

Background:

  • Antiphospholipid syndrome (APLS) is associated with increased neurological complications in systemic lupus erythematosus (SLE).
  • Characterizing cerebral changes on MRI in SLE patients with and without APLS is crucial for understanding disease mechanisms.

Purpose of the Study:

  • To determine and characterize the prevalence of cerebral changes on MRI in patients with antiphospholipid syndrome (APLS) within systemic lupus erythematosus (SLE).

Main Methods:

  • Prospective brain MRI study of 71 SLE patients: 32 with APLS and 39 without.
  • Analysis included atrophy, ventricular enlargement, leukoaraiosis, infarcts, and white matter hyperintensities (WMH).
  • Demographic data, treatment, and SLE activity were also analyzed.

Main Results:

  • Groups were similar in age and gender; disease duration was longer in APLS patients.
  • Cortical atrophy and WMH were common in both groups.
  • Strokes and leukoaraiosis were significantly more frequent in patients with APLS.

Conclusions:

  • Gross brain changes were similar between SLE patients with and without APLS.
  • Increased prevalence of strokes and leukoaraiosis in APLS patients supports an APLS-induced prothrombotic state.
  • MRI findings highlight the importance of considering APLS in SLE patients with neurological events.
