Summary

Antiphospholipid antibodies are strongly linked to stroke, particularly in young patients with a history of thrombosis. This condition involves immune-mediated clotting affecting cerebral vessels and heart valves.

Area of Science:

  • Neurology
  • Immunology
  • Cardiology

Background:

  • Antiphospholipid antibodies are associated with an increased risk of stroke.
  • Patients with these antibodies often present with neurological events at a young age.

Purpose of the Study:

  • To summarize the clinical and pathological features of stroke in patients with antiphospholipid antibodies.
  • To elucidate the underlying pathogenesis of antiphospholipid antibody-associated cerebrovascular events.

Main Methods:

  • Review of retrospective studies on patients with antiphospholipid antibodies and stroke.
  • Analysis of pathological findings in affected cerebral vessels and cardiac valves.

Main Results:

  • Young patients with antiphospholipid antibodies frequently experience stroke, often preceded by other thrombotic events.
  • Common symptoms include headaches and amaurosis fugax; cardiac valvular lesions, especially mitral, are prevalent.
  • Pathology reveals noninflammatory thrombotic occlusion of cerebral vessels and "thrombotic endocarditis."

Conclusions:

  • Antiphospholipid antibodies induce a prothrombotic state contributing to stroke.
  • The pathogenesis involves immune-mediated mechanisms affecting both the brain vasculature and heart valves.
