Abstract

OBJECTIVE:

The polycystic ovary syndrome (PCOS) is a common and complex disease with unclear pattern of inheritance, characterized by an androgen excess, while hyperinsulinemia and insulin resistance (IR) are common features of the syndrome. The angiotensin I converting enzyme (ACE) insertion (I)/deletion (D) gene polymorphism was proved to be involved in many pathophysiological conditions, including hypertension and IR.

DESIGN:

The purpose of this study was to evaluate the involvement of the ACE gene polymorphism in the pathogenesis of PCOS.

METHODS:

In a case-control association study involving 801 PCOS women and 266 healthy controls, hormonal determinations and ACE polymorphism genotyping were performed. The PCOS women were classified into three groups: Group A presented biochemical hyperandrogenism, combined with anovulation and polycystic ovarian morphology; Group B, clinical hyperandrogenism combined with anovulation and polycystic ovarian morphology; and Group C, chronic anovulation and polycystic ovarian morphology.

RESULTS:

A significant increase in the frequency of the DI genotype of the ACE polymorphism was detected in PCOS women as a whole (P=0.035), in PCOS Group A (P=0.039) and Group B (P=0.010), while there was no difference in Group C (P=0.939). Significant difference was also observed in hyperandrogenic PCOS women as a whole (Group A+B) (P=0.017). The II genotype was positively correlated with HOMA-IR and QUICKI and with fasting insulin and glucose/insulin ratio in these groups.

CONCLUSIONS:

The association study of the ACE I/D polymorphism in PCOS women demonstrates an increase in the DI genotype incidence and an association of the II genotype with IR.
