Long-term consequences of polycystic ovary syndrome on cardiovascular risk
2009
Most available data suggest that the prevalence of cardiovascular diseases in women with polycystic ovary syndrome (PCOS) is smaller than expected based on risk calculations during fertile years; therefore, more studies are needed on long-term cardiovascular consequences. Evidence is accumulating that postmenopausal women with PCOS have an increased risk of cerebrovascular events and cardiovascular morbidity. These events are partially related to persisting hyperandrogenism but are mostly correlated with excessive body weight (mainly visceral obesity); this suggests that our best long-term strategy is to ensure that women with PCOS are informed about their high risk for metabolic and cardio…
PCOS: metabolic impact and long-term management.
2012
Polycystic ovary syndrome (PCOS) is the most frequent endocrinopathy in women, affecting up to 10% of those in reproductive age. Furthermore, PCOS presents a lifetime risk of type II diabetes, cardiovascular diseases and endometrial cancer. Women with PCOS have increased cardiovascular risk; however, the risk is not the same in all patients and it is necessary to assess an individual risk profile. There is a discrepancy between increased cardiovascular risk at young age and postmenopausal number of cardiovascular events, probablu depending on changes in androgen ovarian function after the forties. However, changes with age of metabolic profile in women with PCOS have not been studied yet an…
Increased DHEAs levels in PCO syndrome: evidence for the existence of two subgroups of patients
1986
In 49 patients affected by PCO syndrome the serum levels of dehydroepiandroster-one-sulphate (DHEAs) were determined and correlated with the cfinical presentation and the endocrine pattern. Twenty-three patients (47%) had high DHEAs levels (h-DHEAs patients). They presented a milder clinical presentation (low incidence of amenorrhea) than PCO patients with normal DHEAs levels (n-DHEAs patients). In h-DHEAs patients the finding of a normal DHEAs. response to ACTH and of slightly increased 17OHP serum levels suggested that the elevation of serum DHEAs was not due to an adrenal enzymatic deficiency but to a tonic hyperstimulation of the adrenals. Two subgroups of h-DHEAs patients were identifi…
Refractory Acne and 21-Hydroxylase Deficiency in a Selected Group of Female Patients.
2009
<i>Background:</i> Excessive androgen production, suspected in women when acne is accompanied by hirsutism and menstrual irregularities, may be due to congenital adrenal hyperplasia. This inherited disorder of cortisol biosynthesis is caused in more than 90–95% of all cases by 21-hydroxylase deficiency (21-OHD). The steroid 21-hydroxylase gene <i>(CYP21)</i> has a high degree of variability. <i>Objective:</i> This study was conducted to evaluate <i>CYP21 </i>gene mutations in a selected group of women with papulopustular and comedonal acne refractory to treatment, irregular menses and hirsutism. <i>Methods:</i> 30 out of 61 women e…
Low estradiol-to-testosterone ratio is associated with oligo-anovulatory cycles and atherogenic lipidic pattern in women with polycystic ovary syndro…
2010
The estradiol-to-testosterone (E2/T) ratio has been investigated in different diseases but few in vivo data are available with regard to its role in women with ovary syndrome (PCOS). The aim of this study was to evaluate the role of the E2/T ratio in the ovulatory function and metabolic pattern in such women.We retrospectively evaluated hyperandrogenemia, clinical hyperandrogenism, ovarian morphology, hypothalamo-hypophyseal axis and metabolic syndrome parameters in a cohort of 202 consecutive women affected by PCOS. An oral glucose tolerance test measured areas under the curve for insulin (AUC(2hIRI)), for glucose (AUC(2hglucose)), and the HOMA-IR and Matsuda index of insulin resistance we…
The oligomenorrhoic phenotypes of polycystic ovary syndrome are characterized by a high visceral adiposity index: a likely condition of cardiometabol…
2011
BACKGROUND: Women with polycystic ovary syndrome (PCOS) frequently exhibit central obesity, glucose intolerance, atherogenic dys- lipidemia and hypertension, which are characteristic features of a condition of cardiometabolic risk. Our objective was to investigate the relationship between visceral adiposity index (VAI) and phenotypic characteristics in women with PCOS. METHODS: We conducted a cross-sectional case-control study in our Endocrinology Outpatients Clinic. A total of 220 women with PCOS (Rotterdam definition) and I44 age- and BMI-matched healthy women were studied. We evaluated hyperandrogenemia and clinical hyperandrogenism, ovarian morphology, hypothalamic-hypophyseal axis and …
The ratio of androstenedione: 11β-hydroxyandrostenedione is an important marker of adrenal androgen excess in women
1992
To determine if the ratio of serum androstenedione (A):11 beta-hydroxyandrostenedione (OHA) would be helpful in differentiating adrenal from ovarian hyperandrogenism.Prospective study of outpatients being evaluated for hyperandrogenism.Normal women (n = 27), those with hyperandrogenic chronic anovulation (n = 25), and 7 with adult onset of congenital adrenal hyperplasia (CAH) because of 21-hydroxylase deficiency.Fasting serum between 8:00 A.M. and 9:00 A.M. Patients with hyperandrogenic chronic anovulation and CAH received dexamethasone (DEX) 2 mg for 7 days.Serum testosterone (T), unbound T, dehydroepiandrosterone sulfate (DHEAS), A, and 11 beta-OHA by radioimmunoassay.Serum 11 beta-OHA an…
Atherogenic lipoprotein phenotype and low-density lipoproteins size and subclasses in women with polycystic ovary syndrome.
2006
Abstract Context: An altered lipid profile is common in polycystic ovary syndrome (PCOS) and is usually characterized by increased triglycerides and low high-density lipoprotein (HDL)-cholesterol levels. In the general population, these alterations are often associated with the increase of small low-density lipoproteins (LDLs) in the so-called “atherogenic lipoprotein phenotype” (ALP) that determines a further increase of cardiovascular risk. In this study, we evaluated the presence of ALP in the plasma of women with PCOS. Setting: Measurements and analysis of LDL size were performed at the Clinic of Endocrinology, Diabetes, and Clinical Nutrition, University Hospital, Zurich. PCOS patients…
Lower insulin sensitivity differentiates hirsute from non-hirsute Sicilian women with polycystic ovary syndrome
2006
Objective: It is well known that hyperandrogenism and insulin-resistance with or without compensatory hyperinsulinism are closely associated, but the Rotterdam Consensus has concluded that principally obese women with polycystic ovary syndrome (PCOS) should be evaluated for the metabolic syndrome. Our aim was to study insulin sensitivity in PCOS women with hirsutism regardless of obesity. Methods: Clinical characteristics, sex hormones and fasting- and after OGTT-glycemia and insulinemia, homeostatic model of insulin resistance (HOMA IR), and Matsuda index of insulin sensitivity were analyzed in 130 women with PCOS. Hirsutism has been evaluated through the Ferriman–Gallwey (FG) map scoring …
Treatment of hyperandrogenic alopecia in women
2003
Many women with androgenic alopecia have normal circulating androgen levels. Increased scalp sensitivity to androgens may account for these cases. Even when androgen levels are increased, no particular pattern has emerged. Classical anti-androgen measures have proved disappointing, in contrast to the results obtained in women with hirsutism or acne. This study evaluated flutamide and finasteride in 36 premenopausal, hyperandrogenic women presenting with androgenic alopecia. Frontal hair thinning was assessed in photos of the frontoparietal region using the Ludwig grading system. Thirty ovulatory women matched for age and body weight served as a control group. Groups of 12 subjects received …
