Antiphospholipid antibodies and reproduction

Area of Science:

• Reproductive Immunology
• Thrombosis Research
• Autoimmune Diseases

Background:

• Antiphospholipid antibodies (APA) are associated with thrombosis and pregnancy complications.
• Antiphospholipid antibody syndrome (APS) is diagnosed through clinical and laboratory findings.
• APA incidence varies across patient populations, including those undergoing in vitro fertilization (IVF).

Purpose of the Study:

• To review the role of antiphospholipid antibodies in thrombosis and pregnancy loss.
• To examine the efficacy of heparin and aspirin treatment in women with APA.
• To discuss the potential mechanisms of APA in reproductive failure and IVF.

Main Methods:

• Literature review of studies on antiphospholipid antibodies and their clinical associations.
• Analysis of treatment outcomes for recurrent pregnancy loss and IVF in women with APA.
• Discussion of proposed pathogenic mechanisms of APA-induced thrombosis and implantation issues.

Main Results:

• APA are found in significant percentages of women with recurrent pregnancy loss, SLE, and undergoing IVF.
• Heparin and aspirin treatment resulted in successful deliveries in approximately 75% of women with recurrent pregnancy loss and APA.
• Current evidence does not show significant differences in IVF outcomes (implantation, pregnancy rates) with heparin and aspirin treatment, despite ongoing research.

Conclusions:

• Antiphospholipid antibodies play a role in pregnancy complications and thrombosis.
• Heparin and aspirin offer a potential treatment for APA-related recurrent pregnancy loss.
• The impact of APA on IVF success requires further investigation due to their interaction with placental cells.
