Heghine Khachatryan։ Targeting High Risk Antiphospholipid Syndrome in Pregnancy with Hydroxychloroquine

Heghine Khachatryan, Editor-in-Chief of Hemostasis Today, Head of Hemophilia and Thrombosis Center at Yeolyan Hematology and Oncology Center, shared a post on Linkedin:

”Antiphospholipid Syndrome in Pregnancy: Is There a Role for Hydroxychloroquine?

In recent years, the management of obstetric antiphospholipid syndrome (APS) has evolved beyond conventional therapy.

While low-dose aspirin and LMWH remain the cornerstone, an important question emerges:

What should we do in refractory or high-risk APS?

Emerging evidence suggests:

Hydroxychloroquine (Plaquenil) exerts:

  • Anti-thrombotic effects
  • Modulation of aPL-mediated endothelial injury
  • Reduction of placental inflammation and microthrombosis

Clinical data indicate:

  • Improved live birth rates
  • Reduced pregnancy complications
    – particularly in refractory APS

Who may benefit most?

  • Triple-positive APS
  • Refractory obstetric APS
  • APS associated with SLE

Clinical positioning:

Hydroxychloroquine is not first-line, but:

  • A valuable adjunctive therapy
  • Considered in high-risk or treatment-resistant cases

Safety profile:

  • Well-established safety in pregnancy
  • No proven teratogenicity
  • Long-standing use in autoimmune diseases

Key message:
APS in pregnancy is not a uniform entity — it is a risk spectrum requiring precision medicine.

Hydroxychloroquine represents a strategic addition, not for all, but for those who need more than standard therapy.”
