Epidemiology, diagnosis and management of hirsutism: a consensus statement by the Androgen Excess and Polycystic Ovary Syndrome Society.

2012

Background Hirsutism, defined by the presence of excessive terminal hair in androgen-sensitive areas of the female body, is one of the most common disorders in women during reproductive age. Methods We conducted a systematic review and critical assessment of the available evidence pertaining to the epidemiology, pathophysiology, diagnosis and management of hirsutism. Results The prevalence of hirsutism is ~10% in most populations, with the important exception of Far-East Asian women who present hirsutism less frequently. Although usually caused by relatively benign functional conditions, with the polycystic ovary syndrome leading the list of the most frequent etiologies, hirsutism may be th…

Atherogenic forms of dyslipidaemia in women with polycystic ovary syndrome.

2009

OBJECTIVE: Dyslipidaemia is very common in patients with polycystic ovary syndrome (PCOS) but, beyond plasma lipids, atherogenic lipoprotein (Lp) and apolipoprotein (apo) alterations are still ill defined. DESIGN: We measured concentrations of apoB, Lp(a) and small, dense low-density lipoprotein (LDL) in 42 patients with PCOS [age: 28 +/- 7 years, body mass index (BMI): 27 +/- 5 kg/m(2)] vs. 37 age- and BMI-matched healthy controls. METHODS: Elevated Lp(a) levels considered were those > 30 mg/dl while elevated apoB concentrations were those > 100 g/l. RESULTS: Polycystic ovary syndrome showed increased triglycerides levels (p = 0.0011) and lower high-density lipoprotein (HDL)-cholesterol co…

Visceral adiposity index and DHEAS are useful markers of diabetes risk in women with polycystic ovary syndrome

2014

ObjectiveOn the basis of the known diabetes risk in polycystic ovary syndrome (PCOS), recent guidelines of the Endocrine Society recommend the use of an oral glucose tolerance test (OGTT) to screen for impaired glucose tolerance (IGT) and type 2 diabetes (T2DM) in all women with PCOS. However, given the high prevalence of PCOS, OGTT would have a high cost–benefit ratio. In this study, we identified, through a receiver operating characteristic analysis, simple predictive markers of the composite endpoint (impaired fasting glucose (IFG) or IGT or IFG+IGT or T2DM) in women with PCOS according to the Rotterdam criteria.DesignWe conducted a cross-sectional study of 241 women with PCOS in a unive…

Glucose transporter 4 mRNA expression in subcutaneous adipose tissue of women with PCOS remains unchanged despite metformin withdrawal: is there a ce…

2021

Purpose: Metformin induces GLUT-4 mRNA expression in insulin target tissues in PCOS. It is unclear how long this impact is sustained after withdrawal of metformin. We aimed to compare the effect of metformin withdrawal on GLUT-4 mRNA expression in subcutaneous adipose tissue after prior short (ST, 1 year, N = 11) and long term (LT, at least 3 years, N = 13) treatment in obese PCOS women. Methods: At baseline and 6 months after withdrawal, biopsy of subcutaneous adipose tissue followed by quantitative PCR analysis was performed to determine GLUT-4 mRNA expression. Results: We found no time/effect differences in GLUT-4 mRNA expression in ST (2-dCt at baseline 0.42 (0.16–0.48) vs 2-dCt after 6…

Body composition of individuals with polycystic ovary syndrome

2009

Polycystic ovary syndrome (PCOS) is one of the principle forms of hyperandrogenism that affects women of reproductive age. Few studies have evaluated the body composition of patients with PCOS being based mainly on an evaluation of the quantity and distribution of the fat mass. Objectives: to evaluate the body composition of patients affected by PCOS and to establish the hormonal factors that determine possible differences in body composition compared with healthy women. Methods: 110 Caucasian women affected by clinical hyperandrogenism and/or irregular menstrual periods were included in the study; the control group was made up of 90 healthy Caucasian women, of reproductive age, without hyp…

Abdominal fat quantity and distribution in women with polycystic ovary syndrome and extent of its relation to insulin resistance.

2007

Composizione corporea in relazione alla sindrome dell'ovaio policistico. Increased abdominal fat has been linked to insulin resistance and increased cardiovascular risk. Because many patients with polycystic ovary syndrome (PCOS) present abdominal obesity, it may be the cause of insulin resistance in this disorder.Setting: Fat quantity and distribution were evaluated by dual x-ray absorptiometry at the Departments of Clinical Medicine at the University of Palermo and the University of Naples, Italy.Patients: A total of 110 patients with PCOS and 112 weight-matched controls were studied. Anthropometric data, blood glucose, serum insulin, and testosterone were evaluated. Total, trunk, and cen…

Comparison between different mathematical methods to calcolate insulin resistance in women with polycystic ovary syndrome (PCOS)

Influence of sociocultural factors on the ovulatory status of polycystic ovary syndrome.

2009

OBJECTIVE: To evaluate the role of social and cultural differences inside the same ethnic group on the ovulatory status of women with polycystic ovary syndrome (PCOS). DESIGN: To correlate social and cultural status with the phenotypic expression (body weight and ovulation) and with androgen and insulin levels of PCOS. SETTING: University department of medicine. PATIENT(S): Two hundred and forty-four consecutive PCOS women. INTERVENTION(S): All studied patients completed a simple questionnaire to indicate their mean family income and their school education. MAIN OUTCOME MEASURE(S): Ovulation was assessed by measurement of serum progesterone on day 22 of a spontaneous or induced menstrual cy…

Use of fasting blood to assess the prevalence of insulin resistance in women with polycystic ovary syndrome

2003

To determine the prevalence of insulin resistance (IR) in women with polycystic ovary syndrome (PCOS) using baseline fasting blood measurements of glucose and insulin. Prospective clinical study. Academic endocrinology unit in Palermo, Italy. Two hundred and sixty-seven women with PCOS, consecutively evaluated, and 50 consecutively selected ovulating controls. Fasting blood was obtained for glucose and insulin measurements from all women. For 60 women with PCOS and 20 controls an insulin tolerance test (ITT) was also performed. Assessment of normal and abnormal values for fasting insulin, glucose/insulin ratio, and the calculated indices of the homeostasis model assessment (HOMA), quantitat…

How should we manage atherogenic dyslipidemia in women with polycystic ovary syndrome?

2007

Despite their young age, women with polycystic ovary syndrome (PCOS) have increased cardiovascular risk. Besides normal concentrations of low-density lipoprotein (LDL) cholesterol, dyslipidemia is very common and includes elevated triglyceride levels and low high-density lipoprotein cholesterol concentrations. Recent findings also showed that women with PCOS have qualitative LDL alterations, with increased levels of atherogenic small, dense LDL particles. Such lipid abnormalities constitute a common form of dyslipidemia, the so-called atherogenic lipoprotein phenotype (ALP), associated with a greater cardiovascular risk. Weight reduction and increased physical activity may constitute first-…
