[Combined thrombophilic factors among women with late recurrent spontaneous abortions].

The aim of this study was to assess the role of combined thrombophilic factors carrier status for development of late recurrent pregnancy loss (RPL). The polymorphism 4G/5G (PL 4G/5G) - genotype 4G/4G in plasminogen activator inhibitor type 1 (PAI-1), Factor V Leiden (FVL) and prothrombin (FII) gene mutation 20210 G>A in 52 women with recurrent pregnancy loss between 10 and 20 weeks of gestation and in 125 healthy women with at least one uncomplicated full-term pregnancy was investigated. Combined carrier status for thrombophilic factors was more pronounce among women with RPL (7.7%) compared to control subjects (3.2%), (OR=2.52, 95% CI (0.5- 12.62), p-ns). The most common association was between FVL and PL 4G/5G (5.8% compared to 0.8% in patients and controls, OR=7.59, 95% CI (0.68 - 191.04), p-ns). Because of relatively small size of the study, the difference in carrier status between women with RPL and control subjects did not rich statistical significance. A weak association between double carrier status for inherited thrombophilic factors and RPL was established. The strong determination in larger studies of the relation between combined inherited thrombophilic status and RPL development could better specify anticoagulant prophylaxis in further pregnancy
