Maternal thrombophilia and adverse pregnancy outcome: a case-control study

Objective: To assess the risk of adverse pregnancy outcomes in patients with acquired and/or congenital thrombophilia factors. Patients and Methods: A cohort of 130 women with a history of pregnancy loss and no successful gestation were investigated for the presence of congenital and acquired thrombophilia factors, and then compared with a control group of 130 healthy women who had had at least one successful gestation and no pregnancy loss, and were screened for congenital and acquired thrombophilia factors. Results: Acquired and congenital thrombophilia factors were found in 30 (23%) patients and in 14 (10.8%) controls (p < 0.015). The presence of >= 1 congenital thrombophilia factor was associated with pregnancy loss with an odds ratio of 2.46 (p = 0.040). Moreover, women who had had >1 early fetal loss had a 2.85-fold risk of being carriers of congenital thrombophilia factors, compared to the controls. Conclusion: Our study showed the increased risk of miscarriage in patients with congenital thrombophilia factors and >1 early fetal loss.
