Antiphospholipid antibodies (aPL) are linked to stroke, particularly in young women and SLE patients. Lupus anticoagulant (LA) is more common than beta2-GPI aCL in ischemic stroke patients.

Area of Science:

  • Neurology and Immunology
  • Cardiovascular Research

Context:

  • Antiphospholipid syndrome (APS) involves thrombosis and antiphospholipid antibodies (aPL).
  • aPL are implicated in acquired hypercoagulable states leading to stroke and TIA.
  • Atherosclerosis is a prevalent cause of ischemic stroke, with APS identified in 12.5% of young patients.

Purpose:

  • To investigate the incidence and pathogenic role of various antiphospholipid protein antibodies in ischemic stroke.
  • To examine the association between specific aPL, systemic lupus erythematosus (SLE), and carotid atherosclerosis.

Summary:

  • The study analyzed 250 ischemic stroke patients, measuring antibodies including beta2-GPI aCL, IgG aCL, LA, PS-PT, PS, and PI.
  • Incidence rates were: beta2-GPI aCL (2.8%), IgG aCL (12%), LA (9.2%), PS-PT (9.6%), PS (7.2%), and PI (8.8%).

  • Lupus anticoagulant (LA) was more frequent than beta2-GPI aCL. Anti-PS-PT antibodies correlated strongly with LA. aPS and aPI were linked to antinuclear antibodies and increased carotid atherosclerosis markers (IMT, plaque score, stenosis).

    • Impact:

    • Antiphospholipid antibodies are identified as a significant risk factor for stroke, especially in young females and SLE patients.
    • The findings highlight the association between specific antiphospholipid antibodies, SLE, and the development of atherosclerosis.
    • Understanding these links can inform stroke prevention strategies in at-risk populations.
