The link between metabolic features and TSH levels in polycystic ovary syndrome is modulated by the body weight: an euglycaemic–hyperinsulinaemic clamp study

摘要

Objective To evaluate the link among thyroid function, glucose/insulin metabolism and steroid hormones in women with polycystic ovary syndrome (PCOS), and to verify if the body mass index (BMI) might influence the interplay between PCOS features and subclinical hypothyroidism (SCH). Study design Case–control study conducted from January to December 2014. Methods One-hundred fifty-four young women with PCOS, according to Rotterdam criteria, and 88 controls were enrolled in an academic research environment. Anthropometric evaluation, hormonal and lipid assays, oral glucose tolerance test (OGTT) and euglycaemic–hyperinsulinaemic clamp were performed. Hirsutism was assessed with the Ferriman–Gallwey (FG) score. Main results SCH was found in 14% of PCOS subjects and in 1% of controls (P?
