Comparison of PCOS phenotypes in adolescent and young adult Mediterranean women with possible PCOS

PURPOSE

During adolescence, PCOS features are supposed to be in evolution. Because of this, the diagnosis of PCOS in adolescence is often unclear and few studies have compared adolescent and adult PCOS phenotype distribution and features. The aim is to compare phenotypes in adolescents and young adults with PCOS.

METHODS

109 girls aged from 13 to 19 years were retrospectively studied. All patients had a gynecological age > 2 years. 63 patients were adolescents (3-5 years beyond menarche) while 46 patients were young adults (6-9 years beyond menarche). Diagnosis of different PCOS phenotypes (A, B, C, D) was made according to the Rotterdam criteria. Clinical data (menstrual cycles, BMI, presence of hirsutism), androgen circulating levels (total testosterone, androstenedione, dehydroepiandrosterone sulphate) and ovarian morphology by ultrasound were assessed.

RESULTS

109 patients presented PCOS according to the Rotterdam criteria. Phenotype A was by far the most common phenotype (73.4%) followed by phenotype B (21.1%). Only few patients had phenotype C (4.6%) or phenotype D (0.9%). When patients were divided in two groups (adolescent and young adult patients), no significant difference in prevalence and features of the different phenotypes was observed.

CONCLUSION

In this cohort of adolescent and young adult women with PCOS, the progression of age does not change the prevalence and the features of main PCOS phenotypes. It suggests that the Rotterdam criteria might be used also in adolescents, at least in those with 2 or more years of gynecological age, for the diagnosis of PCOS.

11-Oxygenated Androgens Are Biomarkers of Adrenal Volume and Testicular Adrenal Rest Tumors in 21-Hydroxylase Deficiency

CONTEXT

Patients with 21-hydroxylase deficiency (21OHD) have long-term complications, resulting from poor disease control and/or glucocorticoid overtreatment. Lack of optimal biomarkers has made it challenging to tailor therapy and predict long-term outcomes.

OBJECTIVE

To identify biomarkers of disease control and long-term complications in 21OHD.

SETTING AND PARTICIPANTS

Cross-sectional study of 114 patients (70 males), ages 2 to 67 years (median, 15 years), seen in a tertiary referral center.

METHODS

We correlated a mass-spectrometry panel of 23 steroids, obtained before first morning medication, with bone age advancement (children), adrenal volume (adults), testicular adrenal rest tumors (TART), hirsutism, menstrual disorders, and pituitary hormones.

RESULTS

Total adrenal volume correlated positively with 18 steroids, most prominently 21-deoxycortisol and four 11-oxygenated-C19 (11oxC19) steroids: 11β-hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11ketoA4), 11β-hydroxytestosterone (11OHT), and 11-ketotestosterone (11ketoT) (r ≈ 0.7, P < 0.0001). Nine steroids were significantly higher (P ≤ 0.01) in males with TART compared with those without TART, including 11OHA4 (6.8-fold), 11OHT (4.9-fold), 11ketoT (3.6-fold), 11ketoA4 (3.3-fold), and pregnenolone sulfate (PregS; 4.8-fold). PregS (28.5-fold) and 17-hydroxypregnenolone sulfate (19-fold) levels were higher (P < 0.01) in postpubertal females with menstrual disorders. In males, testosterone levels correlated positively with all 11oxC19 steroids in Tanner stages 1 and 2 (r ≈ 0.7; P < 0.001) but negatively in Tanner stage 5 (r = -0.3 and P < 0.05 for 11ketoA4 and 11ketoT). In females, testosterone level correlated positively with all four 11oxC19 steroids across all Tanner stages (r ≈ 0.8; P < 0.0001).

CONCLUSION

11oxC19 steroids and PregS might serve as clinically useful biomarkers of disease control and long-term complications in 21OHD.

Genetic, hormonal and metabolic aspects of PCOS: an update

Polycystic ovary syndrome (PCOS) is a complex endocrine disorder affecting 5-10 % of women of reproductive age. It generally manifests with oligo/anovulatory cycles, hirsutism and polycystic ovaries, together with a considerable prevalence of insulin resistance. Although the aetiology of the syndrome is not completely understood yet, PCOS is considered a multifactorial disorder with various genetic, endocrine and environmental abnormalities. Moreover, PCOS patients have a higher risk of metabolic and cardiovascular diseases and their related morbidity, if compared to the general population.

Hormonal and psychosocial correlates of psychological well-being and negative affectivity in young gynecological-endocrinological patients

To study the relationship between hormones, psychosocial factors and psychological well-being or negative affectivity (NA), 102 women (aged 15-31) responded to the 12-item well-being questionnaire (W-BQ12), with subscales for positive well-being (PWB), negative well-being (NWB) and energy (ENE); the Hospital Anxiety and Depression Scale (HADS), consisting of depression (HADS-D) and anxiety (HADS-A) subscales; the Beck Depression Inventory (BDI), and the Hamilton Depression Scale (HAMD). The univariate analysis revealed significant negative correlations between luteinizing hormone (LH) and HADS-T, HADS-D and HADS-A, and between follicle stimulating hormone (FSH) and HADS-A. Positive correlations were shown for thyroid stimulating hormone (TSH), HADS-T, and HADS-A. Cortisol and prolactin levels strongly correlated with BDI and HAMD scores, respectively. In a multivariate analysis, TSH significantly predicted the mood impairment in HADS-T (β = 0.68) and HADS-A (β = 0.68), while economic status predicted the general well-being (β = 0.75), NWB (β = -0.83), ENE (β = 0.89), and HADS-A (β = -0.63). We could not detect any significant differences in NA or well-being in patients with versus without PCOS or with versus without hirsutism, but almost all psychometric parameters differed significantly according to the economic status. In conclusion, TSH was the only hormonal predictor of overall NA and anxiety, and low-economic status overtrumped the impact of hormones on the psychological well-being.

Of PCOS symptoms, hirsutism has the most significant impact on the quality of life of Iranian women

Introduction

Polycystic ovary syndrome is a common endocrine disorder affecting women both physically and psychologically and can lead to a poor quality of life compared to their normal counterparts. The aim of the present study was to assess the impact of various clinical features of polycystic ovary syndrome on the health-related quality of life of Iranian women diagnosed with this syndrome.

Materials and Methods

A total of 796 women diagnosed with polycystic ovary syndrome, aged 15–49 years, completed the questionnaires, interviews, and medical assessments required for this study. A reliable and validated Persian version of the health-related quality of life questionnaire for polycystic ovary syndrome patients was used. Linear regression models were used to assess the association between the symptoms of polycystic ovary syndrome and health-related quality of life.

Results

The mean age of participants was 28.02 years. 35.4% of the subjects were classified as overweight or obese. Hirsutism, was reported to have the strongest impact on the patients’ health-related quality of life, followed in descending order by body mass index, irregular menses and infertility. The relative level of hirsutism was directly proportional to decrease in health-related quality of life score (p<0.001).

Conclusions

The results of the study found that hirsutism had the strongest impact on the health-related quality of life measures in Iranian women diagnosed with polycystic ovary syndrome. Health care officials need to evaluate in depth the effect of each clinical feature of polycystic ovary syndrome separately and design management strategies, keeping in mind the psychological and physical manifestations.

Should insulin resistance be screened in lean hirsute women?

The role of insulin resistance (IR) is well-documented in obese women with polycystic ovary syndrome (PCOS). Controversies exist concerning the presence of IR in idiopathic hirsutism (IH) or if it is a manifestation of high body mass index (BMI). We aimed to investigate the presence/absence of IR in lean hirsute women. One-hundred fifty-one lean women with hirsutism [96 PCOS (group 1) and 55 IH (group 2)] and 58 age-and BMI-matched healthy controls (group 3) were recruited in the study (mean age 25.21 ± 6.1 versus 26.26 ± 4.6years; BMI 21.79 ± 1.7 versus 22.02 ± 2.2 kg/m(2), respectively). Significantly higher insulin and HOMA-IR, and significantly lower fasting glucose insulin ratio (FGIR), quantitative insulin sensitivity check index (QUICKI), reciprocal insulin, and Raynaud index were detected in groups 1 and 2 than in group 3 (p < 0.05). These IR indices were similar between groups 1 and 2. The number of patients with IR (HOMA-IR > 2, FGIR < 7.2, or QUICKI < 0.357) was significantly higher in groups 1 and 2 than in group 3, but was similar between groups 1 and 2. A higher frequency of IR occurs in lean hirsute women regardless of they having PCOS or IH. IR may contribute to aetiopathogenesis of IH, or may cause some metabolic abnormalities in these patients.

PCOS in adolescence and type 2 diabetes

Polycystic ovary syndrome is a frequent disorder in women of reproductive age that consists of a heterogeneous combination of hyperandrogenism, chronic anovulation, and polycystic ovaries. Hyperandrogenism and anovulation are clearly linked to insulin resistance and compensatory hyperinsulinism, with an ovarian androgenic hyperresponsiveness to circulating insulin. Evidence is increasing that suggests that lipotoxicity, which is a key mechanism in the development of insulin resistance and type 2 diabetes, could also explain the androgen overproduction. During adolescence, diagnosis of polycystic ovarian syndrome (PCOS) may be difficult but is of importance because PCOS increases future risk of type 2 diabetes and metabolic complications. Metabolic perturbations begin early in adolescence and also exist in adolescent relatives of women with PCOS, even before clinical signs of PCOS. Screening for impaired glucose tolerance or type 2 diabetes is also important in this population, and treatment should focus on PCOS clinical manifestations as well as long-term metabolic risk.

Study regarding the microscopic aspects of pilo-sebaceous units after antiandrogen treatment in hirsute women

AIM

To analyze the morphological data of pilo-sebaceous units in hirsute women before and 12 months after the antiandrogen treatment with Cyproterone acetate (CPA) 100 mg÷day.

MATERIALS AND METHODS

Fourteen female patients with idiopathic hirsutism that followed an antiandrogen treatment with CPA were biopsied from the androgen-dependent area of the chin before and 12 months after the treatment. Routine sections were stained with Hematoxylin-Eosin, Masson, Van Gieson, Sirius red and picric-indigocarmine, while additional sections were immunostained for S100 protein and vimentin. Electron microscopy was performed in two cases with Langerhans cell hyperplasia.

RESULTS

On biopsies-stained sections, an increased number of hair follicles, the deeper part of the epithelial sheath of the hair follicle with epithelial buds, hyperplasia of sebaceous glands, and no inflammatory infiltrate were noticed. Langerhans cells identified with S100 protein and vimentin were normal in terms of numbers and distribution. After the administration of the treatment, atrophy of the pilo-sebaceous units was visible in nine (64.2%) cases, while inflammatory infiltrate and cells included in the vacuoles of the basal layer of the epidermis became apparent. In six of the cases treated with antiandrogens, a marked hyperplasia of Langerhans cells was noticed. In conclusion, the benefit of antiandrogen treatments is supported by atrophy of the hair follicle and the sebaceous glands. The activation of Langerhans cells associated with inflammatory infiltrate in the dermis and hair follicles could be considered as a local consequence of the involution process of hair follicles after the administration of the treatment.

The lack of association between idiopathic hirsutism and metabolic disturbances: Iranian PCOS Prevalence Study

BACKGROUND

Idiopathic hirsutism (IH) is a condition diagnosed after other hirsutism related is ruled out. Its definition diagnosis had a dynamic process along with improving the understanding of the various androgen excess disorders. There is uncertainty regarding its health impact and its long-term metabolic consequences. We aimed to compare metabolic syndrome (Mets) and insulin resistance (IR) of Iranian women with IH and a group of healthy controls in a large community-based study.

METHODS

Anthropometric measurements, biochemical parameters, Mets (using Joint Interim Statement criteria) and IR (estimated by the homeostasis model assessment), were compared between 101 women with IH and 423 healthy controls recruited from among 1126 reproductive aged women.

RESULTS

There was a statistically significant difference between the BMI of women with IH in comparison to normal control (27.7 versus 26.7 kg/m(2), p = 0.02); however, the prevalence of android adiposity was similar (26.7% and 24.3%, respectively). The age and BMI adjusted prevalence of Mets and IR are similar in women with IH and controls (30% versus 23.9 and 25.7 % versus 22.5%, respectively).

CONCLUSION

There will be no need for additional cardiometabolic evaluations for women with IH, later in life.

Clinical, hormonal and metabolic characteristics of polycystic ovary syndrome among obese and nonobese women in the Croatian population

Obesity has a deteriorating impact on women with PCOS, although prevalence and the impact of specific traits of PCOS remain inconstant in different populations. Therefore, the aim of this study was to explore the differences in clinical, hormonal and metabolic features between obese and nonobese Croatian women diagnosed as having PCOS according to Rotterdam consensus criteria. The study included 74 obese and 208 nonobese women with PCOS. Clinical, biochemical and metabolic variables were compared among those PCOS subgroups. Obese subjects with PCOS had a higher risk of developing oligo-amenorrhea (OR 3.7; 95% CI, 1.1-12.5) and lower risk for developing hirsutism and acne (OR 0.2; 95% CI, 0.1-0.3 and OR 0.8; 95% CI 0.5-1.4, respectively). Obese PCOS subjects also had a higher risk of developing hyperandrogenemia (OR 2.5; CI 95% 0.9-6.7), insulin resistance (OR 4.5; CI 95%, 2.6-7.9), hypercholesterolemia (OR 5.0, CI 95% 2.5-10.2), hypertriglyceridemia (OR 5.2; 95% CI, 2.9-9.2) as well as elevated serum CRP levels (OR 4.1; 95% CI 1.4-12.2) compared to nonobese PCOS women. In conclusion, nonobese Croatian women with PCOS are more inclined to cosmetic problems associated with PCOS then metabolic ones. This is the first study to report the impact of obesity on acne and irregular menses as a study outcome. Obesity deteriorates menstrual regularity, insulin sensitivity and lipid profile in Croatian women with PCOS; therefore one of the fundamental treatment strategies of PCOS should be obesity prevention.

Clinical and biochemical characteristics of polycystic ovary syndrome in Croatian population

Polycystic ovary syndrome (PCOS) is a common endocrine condition affecting women of reproductive age. There are many typical signs and symptoms that allow for the diagnosis of PCOS depending on the criteria used. Interestingly, ethnicity influences the extent of these signs and symptoms; therefore, the frequency of symptoms varies between different countries and ethnic groups. The prevalence of this syndrome in Croatia is unknown, and it's clinical and biochemical characteristics have not yet been reported. During this study, we used the Rotterdam criteria to evaluate 365 Croatian women with PCOS, and compared them to 304 age matched controls to assess the clinical and biochemical abnormalities that occur in PCOS patients. The mean age of PCOS patients at presentation was 26.1 +/- 5.9 years and of controls were 28.0 +/- 4.2 years. Women with PCOS has significantly higher body mass index (BMI) than the control group, although in both groups most patients had normal weight (76.2% vs. 87.8%). Abdominal distribution of fat tissue was similar in both groups. Menstrual cycle abnormalities were observed in 90.7% of PCOS patients, and ultrasonographic appearance of polycystic ovaries was reported in 97.3% of PCOS cases. Nearly 75% of patients with PCOS had hirsutism and 49.6% had acne. We recorded significantly higher serum levels of luteinizing hormone (LH), total testosterone (TT), free testosterone (fT) and insulin, while the serum levels of sex hormone binding globuline (SHBG) and follicular stimulating hormone (FSH) were significantly lower than in the control group. Serum glucose values were not significantly different between the groups. In conclusion, chronic anovulation, hirsutism and ultrasound appearance of polycystic ovaries are the dominant features of PCOS in Croatian population. The majority of patients with PCOS had normal body weight. The incidence of insulin resistance in this group of patients is less than the previously described frequency in other populations of patients with PCOS and normal weight.

[Diagnosis and management of hirsutism]

Apart from being a source of great distress and social embarrassment, hirsutism may be also a sign of an underlying endocrine or malignant disease. The diagnosis should be always methodical and adjusted to the nature of the clinical presentation. The clinical evaluation of the potentially hirsute patient first involves confirming the presence of hirsutism by hormonal assessment and then excluding underlying disorders or associated abnormalities. There is no uniform treatment approach for the management of hirsutism and the therapy is directed at suppressing ovarian or adrenal androgen production, inhibiting the conversion of testosterone to dihydrotestosterone, or antagonizing the effects of androgens at the receptor level. All these tratment options are reviewed. In this paper, we provide the recommended approach to the diagnosis and treatment of hirsute patient.

Hirsutism, virilism, polycystic ovarian disease, and the steroid-gonadotropin-feedback system: a career retrospective

This career retrospective describes how the initial work on the mechanism of hormone action provided the tools for the study of hirsutism, virilism, and polycystic ovarian disease. After excessive ovarian and or adrenal androgen secretion in polycystic ovarian disease had been established, the question whether the disease was genetic or acquired, methods to manage hirsutism and methods for the induction of ovulation were addressed. Recognizing that steroid gonadotropin feedback was an important regulatory factor, initial studies were done on the secretion of LH and FSH in the ovulatory cycle. This was followed by the study of basic mechanisms of steroid-gonadotropin feedback system, using castration and steroid replacement and the events surrounding the natural onset of puberty. Studies in ovariectomized rats showed that progesterone was a pivotal enhancer of estrogen-induced gonadotropin release, thus accounting for the preovulatory gonadotropin surge. The effects of progesterone were manifested by depletion of the occupied estrogen receptors of the anterior pituitary, release of hypothalamic LHRH, and inhibition of enzymes that degrade LHRH. Progesterone also promoted the synthesis of FSH in the pituitary. The 3α,5α-reduced metabolite of progesterone brought about selective LH release and acted using the GABA(A) receptor system. The 5α-reduced metabolite of progesterone brought about selective FSH release; the ability of progesterone to bring about FSH release was dependent on its 5α-reduction. The GnRH neuron does not have steroid receptors; the steroid effect was shown to be mediated through the excitatory amino acid glutamate, which in turn stimulated nitric oxide. These observations led to the replacement of the long-accepted belief that ovarian steroids acted directly on the GnRH neuron by the novel concept that the steroid feedback effect was exerted at the glutamatergic neuron, which in turn regulated the GnRH neuron. The neuroprotective effects of estrogens on brain neurons are of considerable interest.

[Correlations between clinical signs and hormonal parameters in young women with hirsutism]

Hyperandrogenism is the pathological condition, which clinical signs are "androgendependent dermopathies" (seborrhea, acne, hirsutism, alopecia) and not in every cases evidence with hyperandrogenemia. Free testosterone is the most frequent marker of hyperandrogenism, but its determination routinely not feasible in all laboratories. Therefore, some models for calculating free and bioavailable testosterone have been developed. In women the testosterone sources are not only ovaries and adrenal glands, but also abdominal and peripheral fat. There are many investigations to definite correlations between body mass index, androgens and sex hormone binding globulin. The aim of this study was to define the correlations between clinical, biochemical markers of hyperandrogenism and body mass index, with regard of abdominal obesity in young women with hirsutism. 83 female adolescents (14-20 year) with hirsutism and 20 female adolescents in control group were included. C-peptide, estradiol, total testosterone, sex hormone binding globulin (SHBG) were measured. Free androgen index (FAI), free (cFT) and bioavailable (Bio-T) testosterone were calculated. The levels of C-peptide and glucose were used to compute Homa-IR (homeostasis model assessment for insulin resistance). There were detected significant high levels by all hormonal parameters of hyperandrogenism in women with hirsutism, than in control group. In patients with abdominal obesity were also found significant high levels by all calculated parameters of hyperandrogenism and significant low level of steroid-bind globulin, than in patients with central obesity. In two groups by hirsutism degree were not detected any differences between androgen markers. The findigs of this research suggest, that android obesity in female adolescents with hirsutism can cause harder hyperandrogenism and elevate free androgen index, free and bioavailable testosterone levels. The prophylactic reduction of body mass index may prevent complications.

The insulin response to oral glucose, concentrations of total cholesterol, triglycerides and uric acid in women with idiopathic hirsutism

The glucose and insulin responses to an oral glucose tolerance test, concentrations of total cholesterol, triglycerides and uric acid were evaluated in women with idiopathic hirsutism (IH). Clinical data and laparoscopy of the ovaries were used in diagnosis. According to body weight the patients were divided into two groups: obese (OB-IH) and non-obese (NO-IH). In the IH and NO-IH groups the glucose response was significantly greater than in the control group (p less than 0.05). The insulin response to oral glucose was significantly higher in the IH and OB-IH groups compared with the control group (p less than 0.01). The concentrations of total cholesterol and triglycerides were significantly increased in the IH and OB-IH groups compared to those of normal women (p less than 0.01). All groups had significantly higher levels of uric acid compared with the control group (p less than 0.01). The results of our study suggest that alterations of carbohydrate, lipid and uric acid metabolism are present in patients with IH and further studies are needed to establish their mechanisms.

Steroid biomarkers and genetic studies reveal inactivating mutations in hexose-6-phosphate dehydrogenase in patients with cortisone reductase deficiency

CONTEXT

Cortisone reductase deficiency (CRD) is characterized by a failure to regenerate cortisol from cortisone via 11beta-hydroxysteroid dehydrogenase type 1 (11beta-HSD1), resulting in increased cortisol clearance, activation of the hypothalamic-pituitary-axis (HPA) and ACTH-mediated adrenal androgen excess. 11beta-HSD1 oxoreductase activity requires the reduced nicotinamide adenine dinucleotide phosphate-generating enzyme hexose-6-phosphate dehydrogenase (H6PDH) within the endoplasmic reticulum. CRD manifests with hyperandrogenism resulting in hirsutism, oligo-amenorrhea, and infertility in females and premature pseudopuberty in males. Recent association studies have failed to corroborate findings that polymorphisms in the genes encoding H6PDH (R453Q) and 11beta-HSD1 (Intron 3 inserted adenine) interact to cause CRD.

OBJECTIVE

Our objective was to reevaluate the genetics and steroid biochemistry of patients with CRD.

DESIGN

We analyzed 24-h urine collection for steroid biomarkers by gas chromatography/mass spectrometry and sequenced the HSD11B1 and H6PD genes in our CRD cohort.

PATIENTS

Patients included four cases presenting with hyperandrogenism and biochemical features clearly indicative of CRD.

RESULTS

Gas chromatography/mass spectrometry identified steroid biomarkers that correlated with CRD in each case. Three cases were identified as homozygous (R109AfsX3, Y316X, and G359D) and one case identified as compound heterozygous (c.960G-->A and D620fsX3) for mutations in H6PD. No mutations affecting enzyme activity were identified in the HSD11B1 gene. Expression and activity assays demonstrate loss of function for all reported H6PDH mutations.

CONCLUSIONS

CRD is caused by inactivating mutations in the H6PD gene, rendering the 11beta-HSD1 enzyme unable to operate as an oxoreductase, preventing local glucocorticoid regeneration. These data highlight the importance of the redox control of cortisol metabolism and the 11beta-HSD1-H6PDH pathway in regulating hypothalamic-pituitary-adrenal axis activity.

Insulin sensitivity does not differentiate by hirsutism in non-obese women with polycystic ovary syndrome

OBJECTIVE

Hirsutism is one of the component of polycystic ovary syndrome. According to the Rotterdam Consensus has concluded that principially obese women with polycystic ovary syndrome (PCOS) should be evaluated for the metabolic syndrome. The aim of the present study was to investigate the insulin sensitivity in PCOS women with and without hirsutism regardless of obesity.

MATERIAL AND METHODS

Clinical characteristics, sex hormones and fasting glucose and insulin levels of fifty-eight women with PCOS were analyzed. Hirsutism has been evaluated through the Ferriman-Gallwey (FG) map scoring system.

RESULTS

Twenty-two women (38%) were hirsute. They were not any significant difference between hirsute and nonhirsute women for their sex steroids and insulin sensitivity (P>0.05). There were no correlation among sex steroids, WHR and insulin sensitivity in relation to FG score in the subgroup with hirsutism (P>0.05).

CONCLUSION

Our study suggests that normal weight and overweight women with hirsutism can have normal insulin sensitivity and normal levels of circulating androgens in PCOS women.

Body mass index and ovarian function are associated with endocrine and metabolic abnormalities in women with hyperandrogenic syndrome

BACKGROUND

The aim of this study was to evaluate associations of clinical features, such as hirsutism, polycystic ovaries (PCOs), ovulatory dysfunction, and body mass index (BMI) > or =25 kg/m(2), with metabolic abnormalities in hyperandrogenic women.

METHODS

Hirsutism was based on the modified Ferriman-Gallwey score. Ovulatory function was classified as eumenorrhea, oligomenorrhea and amenorrhea, and PCOs were assessed using the ultrasound criteria recommended in the Rotterdam definition. An oral glucose tolerance test was performed. Different insulin resistance (IR) indices were calculated.

RESULTS

Hirsute women had significantly higher BMI, DHEA sulfate (DHEAS) and free androgen index (FAI), and significantly lower values for sex hormone-binding globulin (SHBG). Women with amenorrhea were younger in comparison to women with eumenorrhea and had significantly higher values for fasting insulin (FI) and 1- and 2-h insulin levels; lower values for glucose to insulin ratio (GIR), quantitative insulin sensitivity check index (QUICKI), and SHBG. Women with PCO had significantly higher levels of LH and low-density lipoprotein (LDL), whereas high-density lipoprotein (HDL) levels were significantly lower. Women with a BMI > or =25 kg/m(2) had significantly higher values for age, fasting plasma glucose, FI, and 1- and 2-h glucose and insulin levels, homeostatic model for assessment of IR (HOMA-IR), homeostatic model for assessment of B-cell function (HOMA-B), and FAI, whereas their GIR, insulin sensitivity index, QUICKI, SHBG, and HDL were significantly lower.

CONCLUSIONS

In women with hyperandrogenic syndrome, BMI> or =25 kg/m(2) and amenorrhea appear to be associated with severe endocrine and metabolic abnormalities.

Estimation of truncal adiposity using waist circumference or the sum of trunk skinfolds: a pilot study for insulin resistance screening in hirsute patients with or without polycystic ovary syndrome

Insulin resistance (IR) is an independent risk factor for cardiovascular disease and is a prevalent metabolic disturbance among women with polycystic ovary syndrome (PCOS). Central adiposity, a marker of IR and an accurate anthropometric method to estimate truncal adiposity, may represent a key clinical tool for IR screening in subpopulations at higher metabolic and cardiovascular risk, such as women with PCOS. The aims of the present study were (1) to investigate the influence of androgens on IR and central obesity in overweight or obese hirsute women with or without PCOS and (2) to test the reliability of the sum of trunk skinfolds (subscapular, suprailiac, and abdominal) to estimate truncal adiposity. This observational, cross-sectional study included 37 hirsute patients with body mass index of 25 kg/m(2) or greater and aged between 14 and 41 years. Twenty-four had PCOS, and 13 had ovulatory cycles, normal androgen levels, and isolated hirsutism, named idiopathic hirsutism (IH). Nutritional, anthropometric, clinical, and laboratory evaluations were performed. Body composition was assessed by measurement of waist circumference and skinfold thickness and by dual-energy x-ray absorptiometry (DXA). Both groups presented similar ages, body mass index, and hirsutism score. The PCOS group had higher androgen levels, homeostasis model assessment (HOMA) index, and fasting insulin levels. Free androgen index was positively associated with HOMA, independent of truncal adiposity (r = 0.441, P = .009). Strong correlations were also observed between truncal adiposity measured by DXA and both the sum of trunk skinfolds (r = 0.863, P = .0001) and waist circumference in hirsute patients (r = 0.947, P = .0001). In our study, IR (HOMA index >/=3.8) was associated with truncal obesity, with a more androgenic profile, and with an unfavorable lipid profile. In conclusion, hirsutism per se appears not to be a risk for IR and related cardiovascular disease unless there is presence of central adiposity and/or abnormal androgen profile as observed in patients with PCOS. Waist circumference and the sum of trunk skinfolds represent accurate methods to estimate truncal adiposity, but waist circumference measurement seems to be the simplest method of clinical screening for IR in hirsute women.

Lower insulin sensitivity differentiates hirsute from non-hirsute Sicilian women with polycystic ovary syndrome

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 system.

RESULTS

PCOS women with hirsutism (57.7% of participants) showed significant higher values of total testosterone levels (P = 0.016), free testosterone (P = 0.027), DHEA sulfate (P = 0.017), and Delta4androstenedione (P = 0.018). They had similar body mass index (BMI) (P = 0.073) and were significantly less insulin sensitive (P = 0.002) than those without hirsutism (42.3% of participants). In women with PCOS and hirsutism, there was a significant correlation between FG score and insulin-sensitivity indexes (HOMA IR, rho = 0.33, P = 0.005; Matsuda index, rho = -0.34, P = 0.003) but not with the androgen levels. Moreover, women with hirsutism showed a significantly greater insulin (P = 0.019), C-peptide (P = 0.002), and glucose (P = 0.024) areas under the curve (auc2h).

CONCLUSIONS

Our study suggests that the increased responsiveness of the pilo-sebaceous unit to androgens seems to be influenced by insulin sensitivity and that insulin resistance should be assessed in all hirsute women with PCOS regardless of their BMI, as insulin resistance was found in hirsute women irrespective of whether they were overweight or obese.

Assessment of insulin resistance in the idiopathic hirsutism

BACKGROUND

Idiopathic hirsutism (IH) is the second most common cause of hirsutism, after polycystic ovary syndrome and occurs in about 15% of hirsute women. There are not many studies showing whether patients with IH also have insulin resistance. In the present study, we aimed to investigate the insulin sensivity in IH with non-obese and changing hormone levels during the hyperinsulinemic-euglycemic clamp.

METHODS

Twenty (20) non-obese women with IH (Group I) ranging in age from 20 to 30 (mean 25 +/- 5) years were studied. Hirsutism in women with normal testosterone (T) levels and regular menstrual cycles is as defined IH. Twenty (20) healthy women (mean age 23 +/- 2 years) (Group II) were included in this study as the control group. Insulin sensitivity was assessed with modified euglycemic insulin clamp technique. Samples of prolactin, luteinizing hormone (LH), follicle-stimulating hormone, adrenocorticotropic hormone (ACTH), dehydroepiandrosterone sulfate, cortisol, estradiol, progesterone, 17-OH progesterone (17-OHP), total T, and free T (FT) were obtained at baseline and at 2nd hour during clamp.

RESULTS

Steady-state (120 min) glucose disposal rates were higher in Group II than Group I (7.51 +/- 0.83 vs. 5.76 +/- 1.89 mg/kg/min). Mean FT, ACTH, cortisol, LH, prolactin and 17-OHP levels were found to have decreased statistically significantly (p < 0.05) in Group I. Mean FT, ACTH, and prolactin levels were found to have decreased statistically significantly (p < 0.05) in Group II during the clamp. Mean baseline levels of FT, LH and prolactin were greater in women with hirsutism than in the control subjects (p < 0.05). Insulin mediated glucose disposal was lower in the normal weight women with IH than in those without hirsutism.

CONCLUSIONS

Mean FT, 17-OHP and dehydroepiandrosterone sulfate levels decreased during euglcemic-hyperinsulinemic clamp in IH.

Cetrorelix suppression test to assess the source of androgen overproduction in postmenopausal hirsutism

A 75-year-old woman presenting with recent onset hirsutism and severely elevated serum androgen levels was evaluated to assess the source of excessive androgen production. Commonly recommended hormonal stimulation and suppression tests, and the usually employed imaging techniques were non-diagnostic. In this report, we describe a new suppression test based on the use of the GnRH receptor antagonist, cetrorelix, to determine whether androgen production was LH-dependent. Cetrorelix, administered in a daily dose of 250 microg subcutaneously, suppressed serum LH within 24 h and reduced serum androgen levels to normal within 48-72 h, indicating that androgen overproduction was of ovarian origin. This diagnosis was confirmed by laparoscopic ovariectomy.

CONCLUSION

The cetrorelix suppression test is a simple procedure that provides valuable information regarding the source of androgen excess in postmenopausal hirsutism.

Evaluation of metabolic risk markers in polycystic ovary syndrome (PCOS). Adiponectin, ghrelin, leptin and body composition in hirsute PCOS patients and controls

OBJECTIVE

Polycystic ovary syndrome (PCOS) patients are abdominally obese and are at increased risk of developing the metabolic syndrome. Low adiponectin and ghrelin levels in PCOS patients could be caused by insulin resistance as well as high testosterone levels.

DESIGN

Adiponectin and ghrelin levels were evaluated in 51 hirsute PCOS patients referred to the outpatient clinic of an academic, tertiary care medical centre and in 63 weight-matched female controls. Relationships between adiponectin, ghrelin, leptin, body composition, testosterone and insulin were examined.

METHODS

Measurements of body composition including waist-hip-ratio (WHR), body mass index (BMI) and whole body dual-energy X-ray absorptiometry scan measures of body fat mass. Measurements of fasting levels of adiponectin, ghrelin, leptin, androgen status, oestradiol, lipid variables and insulin during follicular phase.

RESULTS

Adiponectin levels were significantly decreased in obese PCOS patients compared with weight-matched controls (geometric mean (-2 to 2 s.d.) 5.3 (2.5-11.1) vs 7.3 (3.0-17.4) mg/l, P<0.05). Mean ghrelin was significantly lower in hirsute PCOS patients than in controls (0.6 (0.3 to 1.4) vs 0.8 (0.4 to 1.7) microg/l, P<0.001) and this remained significant after subdividing subjects according to waist circumference and BMI. During multiple regression analysis, testosterone correlated positively with adiponectin and negatively with ghrelin independent of BMI, WHR and total fat mass.

CONCLUSION

Obese hirsute PCOS patients demonstrated significantly lower adiponectin levels than weight-matched controls suggesting a very high risk for the metabolic syndrome. Furthermore, ghrelin levels were decreased in hirsute PCOS patients and showed a significant, negative correlation with testosterone independent of body composition.

New dimensions in Hirsutism

The following is a review of a satellite symposium held at the British Medical Laser Association Meeting, in November 2005. Prof. V.A. Randall gave a comprehensive overview of hormones and hair growth, followed by an in-depth discussion of hirsutism, the therapeutic options, treatment and trends, by Dr. S. Lanigan. Dr. I. Hamzavi concluded the symposium with a presentation of the latest work on eflornithine in combination with laser hair removal. Data were reproduced with the speakers' permission.

Diagnosis of hyperandrogenism: biochemical criteria

Biochemical derangements in ovarian, adrenal, and peripheral androgen production and metabolism play an important role in underlying causes of hyperandrogenism. Specific diagnostic serum markers such as testosterone (total) and dehydroepiandrosterone sulfate (DHEAS), respectively, may be helpful in the diagnosis of ovarian and adrenal hyperandrogenism, respectively. Validated immunoassays or mass spectrometry assays should be used to quantify testosterone, DHEAS and other principal androgens. Free testosterone measurements, determined by equilibrium dialysis or the calculated method, are advocated for routine evaluation of more subtle forms of hyperandrogenism. The skin, with its pilosebaceous units (PSUs), is an important site of active androgen production. A key regulator in PSUs is 5alpha-reductase, which transforms testosterone or androstenedione to dihydrotestosterone (DHT). DHT in blood is not effective in indicating the presence of hyperandrogenism. However, distal metabolites of DHT have been shown to be good markers of clinical manifestations of hirsutism, acne and alopecia. Assays for these peripheral markers need improvement for routine clinical testing.

[Use of yasmin in the treatment of women with polycystic ovary syndrome]

AIM OF STUDY

To prove the clinical efficiency over hyperandrogenism in women with PCOS after the application of the combined oral contraceptive Yasmin containing 30 mcg ethynilestradiol and 2 mg drospirenone.

METHODS

Prospective open study over 15 women taking Yasmin for six months. At the beginning and at the end of the study the following values have been checked--the Ferriman-Gallwey /F-G/ index, BMI, the waist/hip ratio (WHR), some hormonal and biochemical indexes--testosterone, SHBG, immune reactive insulin (IRI), glucose, as well as the values of free androgenic index (FAI) and insulin resistance (HOMA).

RESULTS

All fifteen women completed 6 months of therapy. The drug has been accepted very well. At the end of the study there was a significant improvement of hirsutism, expressed in the decrease of F-G index, accompanied by an increase of testosterone and SHBG values. The carbohydrate parameters haven't changed significantly.

CONCLUSION

Yasmin is an effective drug in the treatment of hyperandrogenism in women with PCOS with few side effects and no significant influence over insulin resistance.

Female pattern hair loss, sebum excretion and the end-organ response to androgens

BACKGROUND

Although female pattern hair loss can be a feature of hyperandrogenism, many women with hair loss show no clinical or biochemical features of androgen excess. It is possible that hair loss in nonhyperandrogenic women is due to a high level of response to androgens by scalp hair follicles. In this study we explored this idea using sebum excretion as a marker of the cutaneous end-organ response to androgens.

OBJECTIVES

To test the hypothesis that hair loss in nonhyperandrogenic women is due to an increased cutaneous end-organ response to androgens.

METHODS

We studied 100 women, 41 with female pattern hair loss (without hirsutism), 29 with hirsutism (with and without scalp hair loss) and 30 subjects without hair problems. We measured hair density on the frontal scalp, forehead sebum excretion, serum free androgen index (FAI), and body mass index (BMI).

RESULTS

The mean FAI was significantly raised in hirsute women compared with nonhirsute women (P < 0.001), but there was no difference in FAI levels between nonhirsute women with and without hair loss. The mean BMI was also significantly elevated in hirsute women (P < 0.01) but there was no difference in BMI between nonhirsute women with and without hair loss. The mean sebum excretion was higher in hirsute women than nonhirsute women but the difference was not statistically significant. There was no difference in sebum excretion between nonhirsute women with and without hair loss. There was no correlation between hair density and sebum excretion.

CONCLUSIONS

Our results show that sebum excretion is not elevated in women with female pattern hair loss. This may indicate that different androgen-response pathways operate in controlling hair growth and sebum excretion. The alternative explanation is that nonandrogenic mechanisms are involved in mediating hair loss in some women.

Recurrent severe hyperandrogenism during pregnancy: a case report

This report describes the case of a 28 year old woman with virilisation occurring in two successive pregnancies. Recurrent maternal virilisation is rare (seven previous reports) and this case is unique in its severity. Differential diagnoses include ovarian disease and fetal aromatase deficiency. New techniques to exclude a fetal cause were used in this case. This patient presented during the third trimester of her first pregnancy with rapid onset of hirsuitism, increased musculature, and deepening voice. A blood hormone profile revealed significant hyperandrogenism (testosterone, 72.4 nmol/litre; normal range, 0.5-3.0). She delivered a normal boy and maternal androgen concentrations returned rapidly to normal (testosterone, 0.8 nmol/litre). She presented two years later, during her second pregnancy, with similar symptoms and biochemistry (testosterone, 47.5 nmol/litre). Again, she delivered a healthy normal boy and androgens returned immediately to normal (serum testosterone, 2.0 nmol/litre). Ultrasonography revealed no evidence of ovarian (or adrenal) masses in either pregnancy. Umbilical cord venous blood sampling and placental assays revealed no evidence of fetal aromatase deficiency. Recurrent hyperandrogenism during pregnancy is rare. Ovarian luteoma rarely recurs and hyperreactio luteinalis does not lead to such pronounced androgen concentrations. Therefore, this patient has a unique ovarian condition that could be harmful to offspring and mother.

Significantly higher adrenocorticotropin-stimulated cortisol and 17-hydroxyprogesterone levels in 337 consecutive, premenopausal, caucasian, hirsute patients compared with healthy controls

OBJECTIVE

To investigate whether elevated ACTH-stimulated 17-hydroxyprogesterone (17OHP) levels are caused by CYP21 genetic defects or by a general adrenal hyperresponsiveness in hirsute patients.

METHODS

A total of 337 hirsute patients were evaluated by Ferriman-Gallwey score, serum testosterone, ACTH-stimulated 17OHP, and cortisol during the follicular phase. A cutoff value of 16 nmol/liter for maximum ACTH-stimulated 17OHP (M17OHP) responses was defined as the upper limit of the 95% confidence interval (CI) for the 97.5 percentile in 42 female controls. All patients were offered total screening of the CYP21 gene, and 252 healthy, premenopausal women with regular menses underwent genetic screening.

RESULTS

Patients were divided into idiopathic hirsutism (IH) (n = 180) and polycystic ovary syndrome (PCOS) (n = 157) groups. M17OHP levels were significantly higher in IH [geometric mean value (nmol/liter +/- 2 sd) 12.2 (4.6-32.3)] and PCOS [11.9 (5.3-27.2)] compared with controls [8.5 (5.1-14.2)] (P < 0.001). A similar percentage of IH and PCOS patients had elevated M17OHP (20.5 vs. 20.8%, not significant), and these also had significantly higher 30-min cortisol levels compared with controls (P < 0.05). The prevalence of CYP21 mutations in patients was 8.6% compared with 6.3% in controls (P = 0.38). Ten of 19 carriers had M17OHP levels below the cutoff limit.

CONCLUSION

The significantly higher ACTH-stimulated levels of cortisol and 17OHP in hirsute patients indicated adrenal hyperresponsiveness in IH and PCOS. CYP21-carrier status could not explain the observed high prevalence of abnormal ACTH-stimulated 17OHP levels in the hirsute population.

[Adrenal function in girls with hirsutism]

The aim of our study was to estimate the adrenal function in hirsute girls.

MATERIAL AND METHODS

57 girls with hirsutism aged from 12 to 19 years, mean age 15.95 years, were involved into the study. The research was performed in early and middle follicular stage. Menstrual disorders were observed in 78% of them. Hirsutism was estimated with Ferriman-Gallwey scale (mean value 13+/-1.58), mean BMI was 22.7. The patients were divided into 3 groups: group 1 with clinical and laboratory symptoms of PCOS, n=29; group 2 with menstrual disorders and without elevated androgen level, n=15; group 3 without menstrual disorders and without elevated androgen level, n=13.

RESULTS

17OHP level was the highest in group I (1.17+/-0.58 ng/ml). Diurnal cortisol profile was regular in all patients. After Synacthen injection cortisol level rose in all groups to the similar values at 60 min. The same stimuli induced intensive 17OHP secretion in group 1 (2.42+/-2.02 ng/ml) at 30 min statistically higher than in group 2 (1.46+/-0.95 ng/ml), (p=0.045). None had 21-hydroxysase defect. There were positive correlation between levels of 17OHP and LH (r=0.38), 17OHP and T (r=0.39), 17OHP and LH/FSH (r=0.40) CONCLUSIONS: 17OHP level in patients with PCOS is significantly higher then in other hirsute girls. High 17OHP and normal cortisol level after Synacthen administration in PCOS girls point that activity of enzymes involved in 17OHP production is augmented.

Paracoccidioidomycosis in a woman with idiopathic hirsutism

Paracoccidioidomycosis, especially the chronic pulmonary form of the disease, is not commonly described in females. Data from in vitro and vivo studies support the hypothesis that estrogens might influence the pathogenesis of paracoccidioidomycosis in humans by inhibition of transition of conidia or mycelia to yeast form of Paracoccidioides brasiliensis. The authors describe a chronic progressive pulmonary form of paracoccidioidomycosis in a woman with idiopathic hirsutism. In addition to estrogens, the present report suggests that other hormonal factors might play an important role in the pathogenesis of paracoccidioidomycosis, including the increased production of 5alpha-dehydrotestosterone frequently described in individuals with idiopathic hirsutism.

Drospirenone for the treatment of hirsute women with polycystic ovary syndrome: a clinical, endocrinological, metabolic pilot study

The aim of this study was to investigate the effects of the new estro-progestinic containing the antimineralcorticoid progestogen drospirenone (DRSP) in women with polycystic ovary syndrome (PCOS). Fifteen hirsute PCOS patients were treated with 30 microg ethinyl estradiol plus 3 mg DRSP for 12 cycles. Ultrasonographic pelvic exams, evaluation of hirsutism scores, and hormonal and lipid profile assays were performed at baseline and after three, six, and 12 cycles of treatment. An oral glucose tolerance test and euglycemic hyperinsulinemic clamp were also performed, except at the third cycle. The treatment was well tolerated, and all women attained satisfactory cycle control. Hirsutism significantly improved from the sixth cycle onward. Body weight and fat distribution as well as blood pressure remained stable throughout the treatment. Plasma levels of LH, testosterone, SHBG, and, consequently, the free androgen index significantly fell from the third cycle on. Dehydroepiandrosterone sulfate and 17-hydroxyprogesterone significantly decreased after six cycles. The treatment did not affect glycoinsulinemic homeostasis. A trend toward an increase was seen for total cholesterol, triglycerides, and high- and low-density lipoproteins (HDL and LDL) plasma concentrations, although all parameters remained within the normal range. No modifications in total cholesterol/HDL and HDL/LDL ratios were induced by the therapy. The ethinyl estradiol/DRSP combination seems to be effective in ameliorating clinical and hormonal features of PCOS.

The investigation of insulin resistance in patients with idiopathic hirsutism

Hirsutism, which is characterized by excessive growth of terminal hair in a male pattern, is a common clinical condition in women. It may result from various causes including polycystic ovary syndrome, nonclassic adrenal hyperplasia, adrenal or ovarian tumors, or it may be idiopathic. Idiopathic hirsutism (IH) is considered to be one of the most common forms of hirsutism. Although not universal, insulin resistance and hyperinsulinemia have been demonstrated in women with polycystic ovary syndrome. Because there are not enough data showing whether patients with IH also have insulin resistance, we intended to investigate the presence/absence of insulin resistance in women with IH. Thirty-two women with IH [mean age, 24.8 +/- 1.2 yr; body mass index (BMI), 24.6 +/- 0.8 kg/m2] and 17 healthy women (mean age, 25.8 +/- 0.6 yr; BMI, 22.5 +/- 0.6 kg/m2) were included in the study. Eight of 32 patients with IH had BMI higher than 30 kg/m2. The presence of insulin resistance was investigated by using basal insulin levels, the oral glucose tolerance test, the i.v. insulin tolerance test, and the homeostasis model assessment (HOMA) score in both groups. Six (18.7%) patients had impaired glucose tolerance (IGT). Overall, patients with IH had significantly (P < 0.05) higher basal insulin levels (10.5 +/- 1.1 mU/liter vs. 5.7 +/- 0.9 mU/liter) and HOMA scores (2.0 +/- 0.2 vs. 1.1 +/- 0.2) and lower plasma glucose disappearance rate values (5.2 +/- 0.2 vs. 6.0 +/- 0.3) than control subjects. However, patients with IGT were notably more obese than the patients with a normal glucose tolerance test. Analyses after omitting the patients with IGT showed that there was still a significant (P < 0.05) difference in terms of basal insulin levels and HOMA scores. Six of eight (75%) obese patients with IH showed IGT. These data suggest that IH is associated with insulin resistance and an increased prevalence of IGT in obese patients.

Metabolic cardiovascular disease risk factors in women with self-reported symptoms of oligomenorrhea and/or hirsutism: Northern Finland Birth Cohort 1966 Study

The metabolic cardiovascular disease (CVD) risk factors of women with self-reported oligomenorrhea and/or hirsutism, which are symptoms of polycystic ovary syndrome (PCOS), were investigated in a general population-based Northern Finland Birth Cohort 1966 Study to determine whether women with PCOS symptoms at 31 yr would be distinguishable from asymptomatic controls in terms of CVD risk factors. A total of 518 cases with oligomenorrhea and/or hirsutism and 1036 randomly selected controls were analyzed. C-Reactive protein (CRP; median, 0.70 vs. 0.60 mg/liter; P = 0.026), triglycerides (mean, 0.97 vs. 0.91 mmol/liter; P = 0.039), body mass index (BMI; mean, 25.1 vs. 24.2 kg/m(2); P < 0.001), and waist/hip ratio (mean, 0.82 vs. 0.81; P = 0.001) were significantly higher, and high-density lipoprotein cholesterol levels were lower (mean, 1.60 vs. 1.66 mmol/liter; P = 0.002) in the cases compared with the controls. Total cholesterol, low-density lipoprotein cholesterol, and blood pressure showed no statistically significant differences between the cases and the controls. In terms of metabolic CVD risk factors, women reporting hirsutism alone were indistinguishable from the control group, and those who reported both oligomenorrhea and hirsutism had the most severe changes in risk factor profiles. Because obesity is strongly related to PCOS symptoms, the analyses were stratified by BMI. After stratification into normal weight (BMI, <25 kg/m(2)), overweight (25 kg/m(2) <or= BMI <30 kg/m(2)), and obese (BMI, >or=30 kg/m(2)) groups, the waist/hip ratio was significantly higher among the overweight cases (mean, 0.84 vs. 0.83; P = 0.04). Among the obese women, high-density lipoprotein cholesterol was significantly lower (mean, 1.32 vs. 1.48 mmol/liter; P = 0.002) among the cases, and triglycerides tended to be higher (mean, 1.43 vs. 1.27 mmol/liter; P = 0.068) than in controls. In conclusion, these results indicate that self-reported symptoms of oligomenorrhea and/or hirsutism, particularly in the presence of both symptoms, may be helpful to identify women with metabolic cardiovascular risk factor accumulation associated with PCOS.

Clinical and metabolic findings in adolescent females with hyperandrogenism

BACKGROUND

The purpose of this study was to characterize the population of adolescent females with laboratory evidence of hyperandrogenism and to explore clinical and laboratory features that may facilitate the diagnosis and management of this condition. We further investigated these characteristics by race, weight, and type of androgen abnormality.

METHODS

A 4-year retrospective chart review was undertaken. Female patients were included if they attended Adolescent Medicine Clinic and had at least one abnormal laboratory parameter on a testing panel that included total and free testosterone, calculated percent free testosterone, and sex hormone binding globulin levels.

RESULTS

Our final sample included 154 females, 70% of whom were white, 28% African-American and 2% of other ethnicities. The mean age was 16.1 years (range 11-23). The mean body mass index (BMI) was 30.4, ranging from 16.6 to 45.0, and 78% were obese (BMI>95th percentile for age). Initial reason for visit included irregular menses in 75.3%, acne or hirsutism in 7.1%, and other reason in 17.5%. Non-whites were more likely than whites to present with other reason for visit (28 vs. 13%, P<0.05). Non-white patients had a higher chronologic and gynecologic age at presentation than whites. Total testosterone was elevated in 82.6% of the non-white compared to 62.0% of the white patient group (P<0.05). There was no difference in BMI or obesity between whites and non-whites. The subgroup of adolescents with an isolated elevated testosterone was leaner, had a younger gynecologic age, and was more likely to have an abnormal glucose to insulin ratio than were those girls with other androgen abnormalities. Of those tested for other metabolic abnormalities, 55% had at least one abnormal lipid value, and 68% had an abnormal glucose to insulin ratio.

CONCLUSIONS

Adolescent females with hyperandrogenism are at risk for other metabolic abnormalities. The higher gynecologic age and higher testosterone levels in our non-white patient group may reflect a delay in referral. Primary care physicians need to be sensitive to signs and symptoms of hyperandrogenism in the non-white population and in lean adolescents.

Increased growth hormone response to clonidine in nonobese normoinsulinemic patients with polycystic ovary syndrome

OBJECTIVE

To assess growth hormone (GH) levels in response to acute clonidine stimulation in nonobese patients with polycystic ovary syndrome (PCOS) in comparison to patients with idiopathic hirsutism (IH) and normal women without hirsutism.

DESIGN

Cross-sectional study. Outpatient clinic, Porto Alegre, Brazil.

PATIENT(S)

Fourteen patients with PCOS, 11 women with IH, and 10 age- and weight-matched normal women without hirsutism were studied. All subjects presented normal body mass index (<25 kg/m(2)) and insulin levels (<25 microIU/mL).

INTERVENTION(S)

Growth hormone levels were assessed in all patients before and 30, 60, 90, and 120 minutes after oral administration of 0.3 mg of clonidine.

MAIN OUTCOME MEASURE(S)

Growth hormone levels before and after clonidine administration.

RESULT(S)

Delta GH and GH levels at 30, 60, and 120 minutes were significantly higher in the PCOS group than in the IH and control groups.

CONCLUSION(S)

The greater GH response to clonidine in nonobese normoinsulinemic PCOS patients observed in this study suggests a dysregulation in GH secretion in these patients. Further studies are required to elucidate the role of GH in the pathogenesis of PCOS and to investigate the existence of an association between androgens, IGF-I, and GH modulation in PCOS.

Comparison of various simple insulin sensitivity and beta-cell function indices in lean hyperandrogenemic and normoandrogenemic young hirsute women

OBJECTIVE

To assess and compare various simple insulin sensitivity and beta-cell function indices in lean, hirsute, young women.

DESIGN

Prospective study.

SETTING

Departments of endocrinology and metabolism at a university and a state hospital.

PATIENT(S)

Seventy-one hirsute young women were classified as hyperandrogenemic or normoandrogenemic.

MAIN OUTCOME MEASURE(S)

Insulin sensitivity and beta-cell function indices derived from a single sample and an oral glucose tolerance test (OGTT).

RESULT(S)

Lean hyperandrogenemic hirsute women have insulin resistance and increased beta-cell function. The most sensitive indices of insulin resistance were total and 1-hour and 2-hour post-challenge insulin levels during OGTT. When a cut-off value of 3.2 or greater for homeostasis model assessment of insulin resistance (HOMA-IR) was accepted, 46% of hyperandrogenemic women and 30% of normoandrogenemic women were insulin resistant. Fasting insulin level was best correlated with the fasting insulin resistance index, HOMA-IR, and Quicky index. The HOMA-IR was best correlated with fasting insulin level and the hepatic insulin sensitivity index (ISI(HOMA)).

CONCLUSION(S)

Insulin levels based on OGTT are the most useful index of insulin resistance and beta-cell function index in hirsute women. The HOMA-IR may be a proposed global test for insulin resistance; it correlated well with both OGTT-derived insulin resistance and beta-cell function indices and with global insulin resistance indices derived from a single sample (such as ISI (HOMA), Quicky index, FIRI(-1), fasting Belfiore index, and glucose/insulin ratio).

Ovarian carcinoid exhibiting double function

A case of a 58-year-old woman with ovarian carcinoid exhibiting double function is reported. She had suffered from constipation and hirsutism before surgery. Pathological examination revealed that many carcinoid tumor cells were immunohistochemically positive for peptide YY, which inhibits intestinal motility and many peripheral steroid cells. After surgery the patient recovered from constipation immediately. Although the serum level of testosterone also immediately decreased, hirsutism remained for about 2 years. These clinical manifestations are considered to be due to peptide hormone-producing tumor parenchymal cells and testosterone-producing functioning stromal cells. This is the first report of clinically manifested double-functioning ovarian carcinoid; one function is due to tumor cells themselves and another function is due to stromal cells.

Dietary composition in restoring reproductive and metabolic physiology in overweight women with polycystic ovary syndrome

Overweight women with polycystic ovary syndrome (PCOS) were randomized to a high protein (HP; 40% carbohydrate and 30% protein; n = 14) or a low protein (LP; 55% carbohydrate and 15% protein) diet (n = 14). The intervention consisted of 12 wk of energy restriction (approximately 6000 kJ/d), followed by 4 wk of weight maintenance. Pregnancies (two HP and one LP); improvements in menstrual cyclicity, lipid profile, and insulin resistance (as measured by the homeostasis model); and decreases in weight (7.5%) and abdominal fat (12.5%) occurred independently of diet composition. Improvements in menstrual cyclicity were associated with greater decreases in insulin resistance and fasting insulin (P = 0.011). On the LP diet, high density lipoprotein cholesterol decreased 10% during energy restriction (P = 0.008), and the free androgen index increased 44% in weight maintenance stages (P = 0.027). Weight loss leads to improvements in cardiovascular and reproductive parameters potentially mediated by improvements in surrogate measures of insulin resistance. An HP weight loss diet may result in minor differential endocrine and metabolic improvements.

Premature pubarche in girls is associated with functional adrenal but not ovarian hyperandrogenism

OBJECTIVE

We hypothesized that there would be evidence of functional ovarian hyperandrogenism in girls with premature pubarche (PP) at diagnosis.

METHODS

White girls <8 years of age and black girls <6 years with PP (n = 15) were studied. Prepubertal girls (n = 13; 5.3-10.9 years) and early pubertal girls (n = 8) served as control subjects. The biochemical marker for functional ovarian hyperandrogenism was the 17-hydroxyprogesterone (17-OHP), androstenedione (AD), and estradiol (E2) response to subcutaneous leuprolide during adrenal suppression with dexamethasone. This was studied in girls with PP and in control subjects.

RESULTS

ACTH stimulated 17-hydroxypregnenolone (17-OH Preg), dehydroepiandrosterone (DHEA), and AD levels, and 17-OH Preg:17-OHP and DHEA:AD ratios were significantly higher in girls with PP than in prepubertal control subjects (n = 18) (P < or =.003). The ovarian response to leuprolide stimulation was comparable in girls with PP and prepubertal control subjects, but the response in prepubertal study subjects was significantly lower than in pubertal control subjects (P =.016 for Delta17-OHP, P =.001 for DeltaAD, and P =.026 for DeltaE2).

CONCLUSIONS

Contrary to the hypothesis, PP in girls was not associated with prepubertal evidence of ovarian hyperandrogenism but was associated with functional adrenal hyperandrogenism.

Anti-androgens for the treatment of hirsutism

Many alternatives exist for treating hirsutism. Based on an analysis of scientific literature and on the experiences of the author, the most common anti-androgen agents are discussed in this review. Androgen receptor blockers (cyproterone acetate, flutamide and spironolactone), 5 alpha-reductase inhibitors (finasteride) and androgen-suppressing agents (gonadotrophin-releasing hormone [GnRH] agonists, oestroprogestins, corticosteroids and insulin-sensitising agents) are evaluated and compared. The importance of diagnosis in choosing the most appropriate anti-androgen treatment is also discussed.

Polycystic ovaries in Hirsute women with normal menses

PURPOSE

Hirsute women with normal ovulatory menstrual function are often diagnosed as having idiopathic hirsutism. We prospectively evaluated 62 hirsute ovulatory women to determine if they had a subtle form of polycystic ovary syndrome, and if they exhibited any of the metabolic abnormalities commonly associated with classic polycystic ovary syndrome.

METHODS

Baseline hormonal profiles, ovarian responses to gonadotropin-releasing hormone agonist, and ovarian morphology by ultrasound were compared in the hirsute women and two groups of ovulatory controls.

RESULTS

Among 62 women, only 8 (13%) had normal androgen levels and were considered to have idiopathic hirsutism. Twenty-four (39%) had characteristic polycystic ovaries on ultrasound, an exaggerated response of 17-hydroxyprogesterone to leuprolide, or both, suggesting ovarian hyperandrogenism and the diagnosis of mild polycystic ovary syndrome. The remaining 30 women (48%) were considered to have unspecified hyperandrogenism. Age, body weight, and androgen level were similar among the hyperandrogenic subgroups. However, when compared with both normal and overweight controls and with patients with idiopathic hirsutism, the women who had mild polycystic ovary syndrome had higher fasting insulin levels [P < 0.01, mean (+/- SD) increase of 7 +/- 3 microU/mL], lower glucose-insulin ratios (P < 0.01, mean reduction of 3 +/- 1.5), higher low-density lipoprotein cholesterol levels (P < 0.05, mean increase of 26 +/- 10 mg/dL), and lower high-density lipoprotein (HDL) cholesterol levels (P < 0.01, mean reduction of 10 +/- 4 mg/dL). Compared with patients who had unspecified hyperandrogenism, these women also had higher fasting insulin levels (P < 0.05), lower glucose-insulin ratios (P < 0.05), and lower HDL cholesterol levels (P < 0.05).

CONCLUSION

These data suggest that mild polycystic ovary syndrome is more common than idiopathic hirsutism, and it is also associated with subtle metabolic abnormalities.

Percutaneous absorption and pharmacokinetics of eflornithine HCl 13.9% cream in women with unwanted facial hair

This article reports the results of an open-label, multiple-dose study to determine percutaneous absorption and pharmacokinetics of eflornithine following topical treatment with eflornithine HCl 13.9% cream (Vaniqa). Ten women with excessive facial hair were treated with two 0.5 g single doses of [14C]-labeled eflornithine HCl 13.9% (w/w) cream (periods A and C) separated by twice-daily application of 0.5 g unlabeled eflornithine HCl 13.9% cream for 7 days (period B). Analysis of radioactivity excreted in urine and feces indicated that percutaneous absorption was minimal. Comparison with urinary excretion of eflornithine in period A suggested that most of absorbed eflornithine was excreted in urine without being metabolized. Radioactivity was not detectable in blood or plasma, but eflornithine concentrations were measurable, with peak concentrations of 4.96 ng/ml in period A and 10.44 ng/ml in period C. Eflornithine was eliminated from plasma with a mean terminal half-life of 11 hours (first application) and 8 hours (final application). Trough plasma concentrations reached steady state (4.61-5.50 ng/ml) after 4 days of twice-daily topical treatment, and multiple dosing had no apparent effect on disposition kinetics. The low degree of percutaneous absorption and low systemic exposure to eflornithine offer a favorable clinical safety profile of eflornithine HCl 13.9% cream.

Adrenocortical hyperresponsivity to adrenocorticotropic hormone: a mechanism favoring the normal production of cortisol in 21-hydroxylase-deficient nonclassic adrenal hyperplasia

OBJECTIVE

To test the hypothesis that patients with nonclassic adrenal hyperplasia (NCAH) exhibit a generalized exaggeration in their response to ACTH stimulation that favors the normal production of F. Patients with 21-hydroxylase (21-OH)-deficient NCAH do not demonstrate cortisol (F) deficiency.

DESIGN

Prospective controlled study.

SETTING

Tertiary university clinic.

PATIENT(S)

Twenty-four untreated patients with NCAH diagnosed by a 17 alpha-hydroxyprogesterone (17-HP) level of >30.3 nmol/L (>10 ng/mL), and 37 age- and body mass-matched healthy eumenorrheic nonhirsute controls.

INTERVENTION(S)

All study subjects underwent a 60 minute acute stimulation using 0.25 mg of ACTH-(1-24) i.v.

MAIN OUTCOME MEASURE(S)

Basal and stimulated serum levels of pregnenolone (PREG), 17-hydroxypregnenolone (17-HPREG), dehydroepiandrosterone (DHA), progesterone (P4), 17-HP, androstenedione (A4), 11-deoxycortisol (S), and cortisol (F).

RESULT(S)

The median basal (i.e., Steroid(0)) or ACTH-stimulated (i. e., Steroid(60)) serum levels of PREG, 17-HPREG, DHA, P4, 17-HP, A4 and, most importantly, S were higher in NCAH patients than in controls. In contrast, the levels of F at either 0 minute or 60 minutes of stimulation were similar between NCAH and control women. The proportion of NCAH patients with stimulated steroids levels of >the 95th percentile of controls were as follows: 84.21% for PREG(60), 87.5% for 17-HPREG(60), 95.8% for DHA(60), 89.5% for P4(60), 100% for 17-HP(60), 91.7% for A4(60), 29.2% for S(60), and 4. 1% for F(60).

CONCLUSION(S)

A generalized adrenocortical hyperresponsivity to ACTH stimulation seems to be present in patients with 21-OH-deficient NCAH, with an exaggerated production of S evident in approximately 30%. The excess production of S in these NCAH patients may, in part, account for their normal F production.

Hirsutism in women. Effective therapy that is safe for long-term use

Hirsutism should be considered part of the androgen-excess syndrome unless another cause (e.g., masculinizing tumor, androgenic-drug use) can be established. Medical evaluation for transient or late-onset androgen excess, polycystic ovary syndrome, and insulin resistance is important because of the risks associated with chronic androgen excess. Treatment of insulin resistance with antiandrogen and/or insulin-lowering therapy can reduce ovarian testosterone levels and hirsutism. Simple laboratory evaluation (i.e., measuring total and free testosterone, DHEAS, and androstenedione) identifies about half of patients with hyperandrogenism. More extensive evaluation and testing are required in the remaining half. Combination therapies, specifically oral contraceptives along with antiandrogen agents, are the most effective. Studies suggest that addition of low-dose GnRH agonist therapy prolongs remission of hirsutism. Most methods produce improvement within 6 months, with continued improvement at 12 months. Successful treatment results in finer hair, decreased rate of growth, decreased need for cosmetic camouflage or removal, and improved appearance. All methods, whether used continuously or intermittently, should be considered long term.

Prostate-specific antigen (PSA) in women

Prostate-specific antigen (PSA) is a valuable tumor marker for prostate cancer. It was believed that PSA was produced exclusively by the epithelial cells of the prostate gland, but a large body of evidence demonstrates that PSA is not a prostate-specific molecule. PSA has been shown to be expressed in many forms of female tissues. The breast is a major female organ able to produce PSA. PSA is detected in both normal and abnormal breast tissues, as well as in various breast fluids including milk, nipple aspirate, and cyst fluid. Androgens and progesterones, via their receptors, regulate the production of PSA in breast tissue. Clinical studies demonstrate that PSA in breast cancer is associated with the expression of estrogen receptor and progesterone receptor. Women with PSA-positive breast cancer have better disease-free survival as well as overall survival than those with PSA-negative breast cancer. PSA levels in nipple aspirate fluid may be indicative of breast cancer risk. High concentrations of PSA are found in amniotic fluid and the levels change with gestational age. Pregnant women have elevated serum PSA. PSA levels in serum also vary during menstrual cycles and increase in women with excess androgen. Clinical implications of PSA in amniotic fluid and female serum have been suggested. More studies are needed to further explore their utilities.

Effects on bone mass of two oral contraceptives containing ethinylestradiol and cyproterone acetate or desogestrel: results of a 2-year follow-up

BACKGROUND

There are conflicting data about the effects of oral contraceptives on bone mass in young women. Moreover, amenorrheic women may also be affected to varying degrees by osteopenia. Both conditions (oral contraceptive use and amenorrhea) are not infrequent in women during their reproductive years.

AIM

To evaluate the safety for bone mass of two oral contraceptives, one containing cyproterone acetate and the other containing desogestrel.

METHODS

A total of 67 women between 19 and 29 years of age were studied. Of these women, 35 were selected to receive an oral contraceptive containing 35 mg ethinylestradiol and 2 mg cyproterone acetate. A second group of 32 women received an oral contraceptive containing 30 mg ethinylestradiol and 150 mg desogestrel for 2 years. Immediately before and after the 12th and 24th months of therapy, bone mineral density was assessed by dual X-ray absorptiometry, and hormonal profiles and Ferriman-Gallwey scores were evaluated.

RESULTS

After the 2-year follow-up, all subjects showed regular cycles, no pregnancies, and no changes in bone mass density. In addition, hirsute subjects showed a decrease of almost 42% in hirsutism scores.

CONCLUSION

Oral contraceptives containing cyproterone acetate or desogestrel in the studied doses have no deleterious effects on bone marrow.

Role of the ovary in the adrenal androgen excess of hyperandrogenic women

OBJECTIVE

To test the hypothesis that ovarian hormones in women with hyperandrogenism alter adrenocortical steroidogenesis.

DESIGN

Combination of two prospective studies.

SETTING

Academic medical centers.

PATIENT(S)

Eighteen hyperandrogenic patients demonstrating hirsutism with either hyperandrogenemia, oligomenorrhea, or both. Eighteen healthy nonhirsute eumenorrheic untreated women served as controls.

INTERVENTIONS

Blood sampling basally and after acute adrenal stimulation with ACTH, before and after 20-24 weeks of leuprolide administration. Nine patients also received 0.625 mg/d of oral conjugated esterified estrogens and 10 mg of medroxyprogesterone acetate days 1-12 of the month (i.e., estrogen replacement therapy [ERT]), whereas the remaining nine did not.

MAIN OUTCOME MEASURE(S)

Before and after the administration of the GnRH agonist (GnRH-a), the basal concentrations of DHEAS; and the levels of androstenedione (A4), DHEA, androstenediol, 11 beta-hydroxyandrostenedione (11-OHA4), and cortisol before and 60 minutes after acute adrenal stimulation, were measured.

RESULT(S)

Levels of DHEAS, androstenediol, and 11-OHA4 decreased by 15%-30%, regardless of whether patients initially had or did not have DHEAS excess. However, only hyperandrogenic patients with elevated levels of DHEAS showed a significant decrease in basal DHEA levels. No statistically significant difference in the response of either androgen to ACTH (1-24) stimulation was noted with ovarian suppression, regardless of initial DHEAS level or use of ERT.

CONCLUSION(S)

We found no evidence that ovarian hormone secretion affected adrenal steroidogenesis, and those women with the highest adrenal androgen levels had the least response to GnRH-a suppression. These findings further support the concept of an intrinsic, and possibly primary, abnormality of adrenocortical steroidogenesis in a subset of hyperandrogenic women that is independent of ovarian abnormalities.

Contraceptive and therapeutic effectiveness of two low-dose ethinylestradiol and cyproterone acetate regimens in the treatment of hirsute patients

OBJECTIVE

To compare the effectiveness of two very low-dose ethinylestradiol and cyproterone acetate regimens in the treatment of hirsutism.

PATIENTS

Eighteen hirsute women were randomized into two different regimens of cyproterone acetate and ethinylestradiol in a reverse sequential pattern: group 1 (0.28 mg ethinylestradiol monthly), group 2 (0.32 mg ethinylestradiol monthly). Both groups received 12.5 mg/day cyproterone acetate for the first 10 days of treatment each month.

MAIN OUTCOME MEASURES

Hirsutism scores were measured according to the Ferriman and Gallwey scoring system and side-effects and complications were recorded during the 6 months of therapy. Ovulation was monitored by radioimmunoassay of estradiol, follicle stimulating hormone (FSH), luteinizing hormone (LH) and progesterone levels. The pituitary response was studied using a gonadotropin releasing hormone test.

RESULTS

Hirsutism scores decreased significantly in both groups at the end of the 6 months (-30%). All patients were anovulatory, as documented by the reduction of the LH, FSH, estradiol and progesterone levels. Pretreatment basal LH and FSH levels were higher than LH and FSH levels during the treatment. Side-effects were observed only occasionally with some differences between the two therapeutic regiments.

CONCLUSION

Both treatments greatly improve hirsutism, reduce clinical problems and side-effects, guarantee both anovulation and contraceptive effectiveness and afford an optimal control of the menstrual cycle.
