Antiphospholipid antibodies in early repeated abortions: a case-controlled study

¹Ospedali Riuniti, Bergamo, Italy.

|October 1, 1988

Summary

Lupus anticoagulant (LAC) and anticardiolipin antibodies (ACA) are linked to recurrent pregnancy loss. This study found these antibodies in women with unexplained recurrent abortions, but not in controls, confirming their association.

Area of Science:

Obstetrics and Gynecology
Immunology
Reproductive Medicine

Background:

Recurrent spontaneous abortion (RSA) is a significant reproductive challenge.
The role of antiphospholipid antibodies in RSA requires further clarification.

Purpose of the Study:

To investigate the association between lupus anticoagulant (LAC) and anticardiolipin antibodies (ACA) and recurrent abortions.
To determine if LAC and ACA are risk factors for unexplained recurrent pregnancy loss.

Main Methods:

A case-controlled study comparing 49 women with recurrent abortions to 141 controls with successful pregnancies.
Detection of LAC and ACA in all participants.

Main Results:

Lupus anticoagulant (LAC) was detected in 14% of women with recurrent abortions versus 0% in controls (p < 0.001).
Anticardiolipin antibodies (ACA) were found in 8% of women with recurrent abortions versus 0% in controls (p < 0.05).
Statistically significant differences in the frequency of LAC and ACA were observed between cases and controls.

Conclusions:

LAC and ACA are significantly associated with a history of recurrent spontaneous abortions.
These antibodies may serve as indicators for immunologic conditions contributing to pregnancy loss in asymptomatic patients.
