Endogenous thrombin potential in polycystic ovary syndrome: the association to body mass index, insulin resistance, and inflammation.

OBJECTIVES

The objective of this study is to investigate plasma endogenous thrombin generation in four different phenotypes of polycystic ovary syndrome (PCOS) defined by Body Mass Index (BMI) and insulin resistance (IR). PCOS is diagnosed according to the Rotterdam criteria.

DESIGN

Multicenter cross-sectional study.

SETTING

Two major University Hospitals in the Capital region of Denmark.

PATIENTS: Hundred forty-eight European women with PCOS were consecutively recruited during April 2010-February 2012. Clinical examination, blood sampling, and DEXA scan were performed.

MAIN OUTCOME MEASURES: Endogenous thrombin potential (ETP).

RESULTS

PCOS women with phenotype BMI > 25 + IR have increased potential of thrombin generation. ETP is associated with total body fat mass, IR, and CRP.

CONCLUSIONS

Obese and insulin resistant women with PCOS have elevated level of ETP corresponding to increased risk of CVD. ETP is related to well-known CVD risk factors in PCOS but not in general to the Rotterdam criteria.
