Study Summary

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of women of childbearing age. PCOS can be individualized into several phenotypes, taking into account in particular the presence of hyperandrogenism, insulin resistance and BMI. Hyperandrogenism and insulin resistance appear to be important factors in the development of cardiovascular cardiovascular disease. In addition, patients frequently use anti-androgenic and/or contraceptive treatments contraceptives, such as combined hormonal contraception (CHC), the use of which is associated with an increased cardiovascular and thrombo and venous thrombosis (VTE). A meta-analysis published in 2020 by Gariani et al.

based on three large studies, estimated the risk of VTE in women with PCOS after adjustment for obesity and hormone therapy. This risk was significantly higher compared with women without PCOS (pooled OR 1.89, CI95% 1.60-2.24). No study has looked specifically investigated the risk of VTE according to different PCOS phenotypes. Such data would be very useful in clinical practice, as it would enable monitoring, contraceptive treatment and anti-androgenic anti-androgen treatment according to the PCOS phenotype, while limiting risks. Assessing the differences PCOS phenotypes is limited by the large sample size required. required. VTE is a rare event in women of childbearing age, and the number of PCOS phenotypes is high.

PCOS phenotypes. Intermediate markers of VTE risk are used in these situations. These markers are thrombin generation tests (notably ETP) and their sensitivity to activated protein C (nAPCsr) and thrombomodulin (nTMsr), as well as sex-hormone binding globulin (SHBG).
