BackgroundPatients with polycystic ovary syndrome (PCOS) have an increased prevalence of thrombophilia, leading to higher rates of pregnancy loss. The aim of this study was to determine the association between thrombophilia and recurrent pregnancy loss (RPL) in patients with and without PCOS.MethodsIn this comparative case-control study, we included 60 patients with RPL (≥3 consecutive pregnancy losses at <20 weeks of gestation) and PCOS (Group 1), 60 patients with PCOS and without RPL (Group 2), 60 patients with RPL and without PCOS (Group 3), and 60 healthy individuals (Group 4). These four study groups were compared regarding serum levels of testosterone, fasting insulin, homocysteine (Hcy), plasminogen activator inhibitor activity (PAI-Fx), protein C, protein S, antithrombin III, activated protein C ratio (APCR), factor V Leiden, prothrombin G20210A, and methylene tetrahydrofolate reductase gene mutations.ResultsPatients in Group 1 had significantly higher levels of testosterone (p = 0.026), dehydroepiandrosterone sulfate (p = 0.035), fasting insulin (p = 0.015), Hcy (p = 0.036), and PAI-Fx (p = 0.008) compared to Group 3. They also had higher proportions of APCR (p = 0.009) and a higher prevalence of factor V Leiden mutations compared to Group 3 (p = 0.001). However, there was no significant difference in protein C (p = 0.088), protein S (p = 0.514), or antithrombin III (p = 0.627) between the four study groups.ConclusionHyperinsulinemia, hyperandrogenemia, hypofibrinolysis, and hyperhomocysteinemia as well as APCR and factor V Leiden mutations are associated with RPL in patients with PCOS.Copyright © 2013.
