Abstract

This study was designed to analyze the changes in circulating factor seven activating protease (FSAP) levels in association with the thrombophilic state of 40 women with recurrent pregnancy loss (RPL). All women were trying to conceive and were prospectively followed up until the achievement of spontaneous pregnancy. The results obtained showed that plasma FSAP activity levels were higher in RPL than in fertile women (P < .001) and represented an adverse predictor of pregnancy at multivariate analysis (P = .002). In 7 consenting RPL women, FSAP activity levels increased continuously during pregnancy until the third trimester, remained elevated immediately after delivery, and declined 6-week postpartum, although at levels that were still above the range of control women. These results suggest that FSAP activity levels might provide useful information during pregnancy progression in at-risk women, possibly acting as a predictive factor for adverse pregnancy outcome in RPL even in the absence of other well recognized thrombophilic conditions.
