Summary

Women with recurrent miscarriage, with or without antiphospholipid syndrome (APS), face a similar long-term risk of thrombosis. This finding impacts understanding of thrombotic risks in reproductive health.

Area of Science:

  • Reproductive Medicine
  • Hematology
  • Obstetrics

Background:

  • Recurrent miscarriage is linked to antiphospholipid syndrome (APS) and prothrombotic states.
  • Antiphospholipid syndrome (APS) is an autoimmune condition that increases the risk of blood clots.

Purpose of the Study:

  • To investigate if women with APS-related recurrent miscarriage have a higher thrombosis risk compared to those with idiopathic recurrent miscarriage.
  • To compare long-term thrombotic event rates between APS-associated and idiopathic recurrent miscarriage cohorts.

Main Methods:

  • Retrospective case-control study involving 141 women with recurrent miscarriage and APS, matched with 141 women with idiopathic recurrent miscarriage.
  • Validated questionnaires were used for data collection over a mean follow-up of 7.3 years.

  • A subgroup analysis included women with initial presentation of recurrent miscarriage, thrombosis, and APS.

    • Main Results:

    • The incidence of thrombosis was comparable between the APS-associated recurrent miscarriage group (6/1000 women-years) and the idiopathic recurrent miscarriage group (2/1000 women-years).
    • Statistical analysis showed no significant difference in thrombosis risk (P = 0.18).
    • All eight women with initial presentation of recurrent miscarriage, APS, and thrombosis experienced subsequent thrombotic events.

    Conclusions:

    • Both idiopathic recurrent miscarriage and APS-associated recurrent miscarriage carry a similar long-term risk for thrombosis.
    • These findings suggest that APS diagnosis does not significantly alter the long-term thrombotic risk in women with recurrent miscarriage compared to idiopathic cases.
