Summary

Systemic lupus erythematosus (SLE) can cause brain pathology, primarily microinfarcts. Cerebral microinfarcts were linked to seizures in SLE patients, highlighting a key neurological manifestation.

Area of Science:

  • Neurology
  • Rheumatology
  • Pathology

Background:

  • Systemic lupus erythematosus (SLE) is an autoimmune disease with potential neurological complications.
  • Neuropsychiatric lupus (NPSLE) encompasses a range of central nervous system manifestations.
  • Understanding the neuropathology of SLE is crucial for diagnosis and management.

Purpose of the Study:

  • To investigate the brain pathology in patients with systemic lupus erythematosus (SLE).
  • To correlate clinical neuropsychiatric SLE manifestations with histopathological findings.
  • To identify the predominant neuropathological abnormalities in SLE.

Main Methods:

  • Autopsy brain examination of 10 patients with SLE.
  • Clinical data review for neuropsychiatric SLE manifestations.
  • Histopathological analysis for microinfarcts, vasculitis, and other lesions.

Main Results:

  • Brain pathology was found in 10 SLE patients; 7 had clinical NPSLE.
  • Multifocal cerebral cortical microinfarcts due to microvascular injury were the most common finding (4 patients).
  • Cerebral microinfarcts showed a significant association with seizures (p < 0.05).

Conclusions:

  • Cerebral microinfarcts represent a key neuropathological feature of SLE.
  • Clinical-pathological classification of NPSLE showed 70% agreement.
  • No correlation was found between NPSLE and tested autoantibodies.
