Leptin-to-adiponectin, adiponectin-to-leptin ratios, and insulin are specific and sensitive markers associated with polycystic ovary syndrome: a case-control study from Bahrain.

Objective: Hyperinsulinemia and adipokines such as leptin and adiponectin with respective proatherogenic and antiatherogenic properties are reported to be the major contributors to pathogenesis of polycystic ovary syndrome (PCOS), including to the development of type 2 diabetes and coronary artery disease. In this study, the association of hyperinsulinemia, hyperleptinemia, hypoadiponectinemia, high leptin-to-adiponectin (L/A) and adiponectin-to-leptin (A/L) ratios as risk factors associated with PCOS in Bahraini women was investigated.

Participants And Methods: Serum levels of insulin, leptin, adiponectin, cholesterol, triglyceride, A/L and L/A ratios were compared in women with PCOS and controls to investigate tentative and potential diagnostic markers for women with PCOS.
