Summary

Antiphospholipid antibodies increase stroke risk. While treatments exist, the exact mechanisms driving thrombosis and optimal therapies for these antibodies remain unclear.

Area of Science:

  • Immunology
  • Hematology
  • Neurology

Background:

  • Antiphospholipid antibodies (aPL) are linked to thrombo-occlusive events, notably stroke.
  • These antibodies target negatively charged phospholipids or their protein complexes.
  • The exact pro-thrombotic mechanisms of aPL are not fully understood.

Purpose of the Study:

  • To review the history, definition, and clinical associations of antiphospholipid antibodies.
  • To discuss the current understanding of aPL-associated thrombosis.
  • To examine existing and potential treatment strategies for aPL-related conditions.

Main Methods:

  • Literature review of historical data and recent research.
  • Analysis of epidemiological studies on stroke risk.
  • Synthesis of current knowledge on aPL pathophysiology and treatment.

Main Results:

  • Antiphospholipid antibodies are associated with an increased risk of initial stroke.
  • The association with recurrent stroke risk is less clear.
  • Antithrombotic therapies are standard but not definitively optimized.

Conclusions:

  • Antiphospholipid antibodies represent a complex clinical entity with significant thrombotic risks.
  • Further research is needed to elucidate the precise mechanisms of aPL-induced thrombosis.
  • Defining optimal antithrombotic strategies remains a critical unmet need in managing aPL-associated conditions.
