RESUMO

Hirsutism is a dermatological condition that refers to the excessive growth of hair in androgen-sensitive areas in women. Recently, the enhancement of the visible signs of a hairy female has taken special concern that affected the quality of life. The present study was developed to compare the follicular targeting effect of topical spironolactone (SP) or progesterone (PG)-loaded nanostructured lipid carrier (NLC) on the management of hirsutism. Four NLC formulations were prepared using cold homogenization techniques and pharmaceutically evaluated. SP-NLC and PG-NLC topical hydrogels were prepared to explore their pharmacological effect on letrozole induced polycystic ovarian syndrome (PCOS) in rats. Inflammatory mediators, antioxidant, and hormonal parameters were assayed. Additionally, histopathological examination was carried out to confirm the successful induction of PCOS. Results confirmed that all NLC formulations have a spherical shape with particle size ranged from 225.92 ± 0.41 to 447.80 ± 0.66 nm, entrapment efficiency > 75%, and zeta potential (- 31.4 to - 36.5 mV). F1 and F3 NLCs were considered as selected formulations for SP and PG, respectively. Female Wistar rats treated with F1 formulation for 3 weeks displayed better outcomes as manifested by the measured parameters as compared to the other tested groups. A significant reduction in hair follicle diameter and density was observed after topical application of SP or PG nano-gels. Finally, the outcomes pose a strong argument that the development of topically administered SP-NLC can be explored as a promising carrier over PG-NLC for more effectual improvement in the visible sign of hirsutism.

RESUMO

PURPOSE: The study aimed to investigate whether repeat number in the androgen receptor (AR) gene has any contribution to phenotypes of the disease of androgen excess (polycystic ovary syndrome (PCOS), idiopathic hyperandrogenemia (IHA) and idiopathic hirsutism (IH) in a cohort of Turkish women. METHODS: Three hundred and fifty-four voluntary premenopausal women (172 healthy controls and 182 patients with androgen excess disorders and idiopathic hirsutism) 18-45 years of age seen at an outpatient endocrine clinic at Erciyes University Hospital between January 2013 and December 2014 were included. All volunteers have undergone physical examination and biochemical evaluation. The polymorphic (CAG)n repeat of the human AR was determined by fragment analyses. RESULTS: Detailed clinical analyses of the patients ended up with 137 PCOS, 24 IHA, and 21 IH. Pairwise comparisons revealed the CAG repeat number differences between the PCOS and controls (p = 0.005) and IH and controls (p = 0.020). Women with CAG repeat length ≤ 17 had a significantly increased twofold risk for PCOS than those women with > 17 CAG repeats OR: 2.0 (95% CI 1.2-3.3, p = 0.005). Women with CAG repeat length ≤ 17 had a significantly increased threefold risk for IH than those women with > 17 CAG repeats OR: 2.9 (95% CI 1.2-7.3, p = 0.020). When correlation analysis was performed, a weak negative correlation was detected between the short allele and FGS score (r = - 0.131, p = 0.013) and a positive relationship between total testosterone and longer allele in the IHA group (r = 0.425, p = 0.039). Median repeat length of the shorter allele between oligomenorrhea and woman with normal menstrual cycle was found to be statistically significant (p = 0.017). CONCLUSION: This study indicated that the risk of PCOS and IH is associated with the inheritance of ARs with shorter CAG repeats.

RESUMO

The aim of this retrospective study was to evaluate the effects of a long-term treatment with α-lipoic acid (ALA) combined with myo-inositol (MI) on clinical and metabolic features of women with polycystic ovary syndrome (PCOS). Fifty-seven women with PCOS and a history of oligoamenorrhea were treated with MI and ALA (800 mg + 2000 mg per day). Forty-four of them had complete clinical charts and were considered eligible for the study. Information about cycle length and body mass index (BMI) was checked after 6, 12, and 24 months. After 12 months ovarian volume, total testosterone plasma levels and changes in hirsutism were also evaluated. The metabolic parameters were evaluated in 16 women after 6 and 18 months of the treatment. Cycle length was significantly reduced at 6 (p < .001), 12, and 24 months of treatment (p < .01). BMI showed a reduction only at 6 months (p < .05), thereafter returning similar to the basal values. No changes of testosterone and ovarian volume were observed. HOMA-IR and fasting insulin were unchanged, but the insulin response to a 3 h OGTT was improved after 6 (p < .01) and 18 months (p < .05) of treatment. No individual suffered from any adverse event. In conclusion, the combination of ALA and MI showed to be useful as long-term therapy in PCOS women, providing a normalization of the menstrual cycle and an amelioration of insulin levels with a high tolerability.

RESUMO

Aim: To investigate the role of serum OKL38 levels in the development of polycystic ovary syndrome (PCOS) and clinical implications related to PCOS.Method: PCOS (n = 33) and ovulatory controls (n = 48) were recruited for the study. Anthropometric measurements were recorded, and blood samples for hormonal and biochemical parameters including serum OKL38 levels were obtained. The potential role of OKL38 on the development of PCOS, metabolic syndrome and cardiovascular disease (CVD) were investigated. Framingham risk score (FRS) was used for the determination of CVD risk.Results: Mean Ferriman-Gallway (FG) score, insulin, low-density lipoprotein (LDL), total cholesterol (TC) levels, and the homeostasis model assessment of insulin resistance index (HOMA-IR) were significantly increased (p < .05) in women with PCOS compared to controls. PCOS group had lower mean OKL38 level compared to controls (p < .0001) and OKL38 was negatively predictive for the diagnosis of PCOS after adjustment of variables that were significantly different between two groups. A negative association between OKL38 and metabolic syndrome in PCOS women was evident after adjustment for age, obesity, and abdominal obesity. OKL38 level was also negatively correlated with body mass index, waist-to-hip-ratio, fat composition, serum TC, LDL, free testosterone levels, FRS, and FG scores.Conclusion: OKL38 may have a partial role in the etiopathogenesis of PCOS and may protect development of metabolic syndrome and CVD in women with PCOS.

RESUMO

Primary retroperitoneal mucinous cystadenomas (PRMC) are rare benign neoplasms with only 55 documented cases in the English literature so far. A 19-year-old female exhibited hirsutism and was found to have a cystic mass measuring 5.8 cm × 3.9 cm × 5.8 cm in the left retroperitoneum. During subsequent work up, a high pre-operative value of dehydroepiandrosterone sulfate (DHEA-S) was noted. The patient was referred to surgical oncology and underwent an uneventful laparoscopic cystectomy. Pathology classified the cyst as PRMC. Post-operatively, the patient's DHEA-S levels normalized, though there was no appreciable decrease in the patient's hirsutism in the short-term follow-up. The origin of PRMC is uncertain. Due to their unknown biological potential, surgical resection is usually recommended. To the best of our knowledge, this is the first report documenting a PRMC and elevated levels of androgens in conjunction with hirsutism.

RESUMO

Background/aim: In the differential diagnosis of hirsutism, early follicular basal 17-OH-progesterone levels sometimes overlap with the diagnosis of late onset congenital adrenal hyperplasia (LOCAH) and other causes of hyperandrogenism. This study aims to investigate the role of some common tests and clinical findings in differential diagnosis in such cases. Materials and methods: One hundred seventy-five female patients with hirsutism and mildly high initial 17-OH-progesterone levels (2-10 ng/mL) were included in the study. The cases were divided into three groups according to their diagnosis: LOCAH (n = 16, mean age = 26.1 ± 6.9), polycystic ovary syndrome (PCOS) (n = 122, mean age = 23.9 ± 5.1), and intracranial hypertension (IH) (n = 37, mean age = 25.2 ± 7.3). Clinical signs and symptoms, such as menstrual irregularity and hirsutism score, and hormone levels including total testosterone and dehydroepiandrosterone sulfate (DHEAS), were compared between the groups. Results: There was no difference between the groups with PCOS, LOCAH, and IH for total testosterone level results (P = 0.461). The DHEAS level was higher in the PCOS group than in the LOCAH group (449.6 ± 151.14 vs. 360.31 ± 152.40, P = 0.044). While there was no difference between the PCOS and LOCAH groups in terms of menstrual irregularity (P = 0.316), the hirsutism score for IH was significantly lower than those of PCOS and LOCAH (9.2 vs. 12.2 and 11.1, respectively; P < 0.001). Basal 17-OH-progesterone levels were higher in the LOCAH group than in the other groups (P = 0.016). Conclusion: While DHEAS level was lower in LOCAH than in PCOS, it was not different from that in IH. While the severity of hirsutism was higher in LOCAH than in IH, it was not different from that in PCOS. Menstrual irregularity was similar between PCOS and LOCAH. According to these results, although the auxiliary tests and clinical findings for the diagnosis of LOCAH contribute to the clinical interpretation, they are not superior to the 17-OH-progesterone level for diagnosis.

RESUMO

We undertook a comprehensive search of all published original articles evaluating the diagnostic value of prostate-specific antigen (PSA) for the detection of polycystic ovary syndrome (PCOS). Finally, 25 studies with a total of 1865 participants (1104 cases and 761 controls) met the inclusion criteria. Mean serum PSA levels were significantly higher in PCOS women compared to healthy women [Standardized mean difference (SMD)=1.73 ng/ml, 95% CI=1.22 to 2.25, p<0.001]. Only 5 studies reported accuracy indicators and were included in the bivariate random-effects model; with a total of 509 samples that included 332 (65.22%) confirmed PCOS women. The sensitivity of serum PSA for the diagnosis of PCOS varied between 66.3 and 90.6%, and, the specificity ranged from 62.5-86.7%. Meta-analysis revealed a pooled sensitivity of 72.3% (95% CI 67.1-77.00%) and specificity of 74.6% (95% CI 67.5-80.8%) with an area under the summary ROC curve equal to 0.82 (95% CI 0.75-0.83). The summary estimates were 2.92 (95% CI 1.98-4.31) for positive LR and 0.37 (95% CI 0.26-0.51) for negative LR. The pooled estimate of diagnostic odds ratio (DOR) of serum PSA was 9.01 (95% CI 4.35-18.64). Considering the methodological weaknesses existed in studies, lack of sufficient data regarding the accuracy indicators, and the complexity of the exact pathophysiology of PSA secretion in women, the precise position of PSA, as a diagnostic test for the detection of PCOS, in clinical practice is undetermined, and further studies are still needed.

RESUMO

Androgens, both in excessive and depleted states, have been implicated in female reproductive health disorders. As such, serum testosterone measurements are frequently ordered by physicians in cases of sexual dysfunction and in women presenting with hirsutism. Commercially available androgen assays have significant limitations in the female population. Furthermore, the measurements themselves are not always informative in patient diagnosis, treatment, or prognosis. This article reviews the limitations of serum androgen measurements in women suspected to have elevated or reduced androgen action. Finally, we consider when therapeutic use of androgen replacement may be appropriate for women with sexual interest/arousal disorders.

RESUMO

BACKGROUND The purpose of our study was to investigate the association between polycystic ovary syndrome (PCOS) and hearing thresholds. MATERIAL AND METHODS Forty women diagnosed with PCOS (mean age, 24.33±6.38 years) and 40 healthy women controls (mean age, 26.38±6.75 years) were included in prospective study. Each case was tested with low (250, 500, 1000, and 2000 Hz), high (4000, 6000, and 8000 Hz) and extended high (EH) (9000-20000 Hz) frequency audiometry. The fasting plasma glucose, insulin, FSH, LH, total testosterone, and sex hormone-binding globulin were measured in all patients. RESULTS The mean hearing thresholds at EH frequencies were statistically significantly higher in the PCOS group than in the control group (p=0.001 right ear and p=0.015 left ear). There were significant positive correlations among free testosterone index (FTI) values and hirsutism scores with EH frequency hearing thresholds. CONCLUSIONS At pure-tone audiometry (PTA) EH frequencies, we detected significantly higher hearing thresholds in PCOS patients than in controls. We also determined that elevated FTI and hirsutism score were positively correlated with elevated hearing thresholds in EH frequencies. These findings support that hyperandrogenism can play a role in the elevation of hearing thresholds in PCOS.

RESUMO

The aim of this study was to evaluate and compare the effects of spironolactone and spironolactone plus metformin treatments on body mass index (BMI), hirsutism score, hormone levels, and insulin resistance in women with polycystic ovary syndrome (PCOS). Thirty-seven patients with PCOS were randomly assigned to receive spironolactone 100 mg/d (spironolactone group, 18 patients) or spironolactone 100 mg/d plus metformin 2000 mg/d (combination group, 19 patients) for 12 months. BMI, modified Ferriman-Gallway score (FGS), serum levels of regarding hormones, and homeostasis model assessment of insulin resistance (HOMA-IR) index were assessed before and after the treatments. Six patients in the spironolactone group and four patients in the combination group reported inter-menstrual vaginal bleeding during treatments. In hirsutism scores, the spironolactone therapy resulted in 25.2% reduction, while combination therapy resulted in 28.3% reduction (p > 0.05, between groups). When the groups were compared in terms of percent changes in BMI, FGS, HOMA-IR, and hormone values other than free testosterone, no significant difference was noted. In the present study, FGSs were significantly decreased in both groups; however, combination therapy was not more effective than spironolactone alone in terms of BMI, FGS, hormone levels, or insulin resistance.

RESUMO

We aimed to determine plasma levels of growth and differentiation factor (GDF)-9 and GDF-15, and their possible association with bone turnover parameters and bone mineral density (BMD), in patients with polycystic ovary syndrome (PCOS). Forty-two obese PCOS women aged 25-35 years, 23 women with idiopathic hirsutism (IH) and 20 healthy controls matched for age and body mass index were enrolled. Anthropometric, metabolic and hormonal patterns, plasma GDF-9 and GDF-15 concentrations, bone turnover markers and BMD were measured. No significant differences were observed in bone turnover markers, BMD measurements, plasma GDF-9 and GDF-15 levels in subjects with PCOS compared with the other two groups. In the combined population of all three groups, GDF-15 concentrations were negatively correlated with osteocalcin (r = -0.317, p < 0.01). Analysis of PCOS patients showed a significant correlation of GDF-15 concentrations with age and homeostasis model assessment index (r = 0.319, p < 0.05, and r = 0.312, p < 0.05, respectively). In addition, GDF-15 concentrations were negatively correlated with osteocalcin (r = -0.395, p < 0.01) and positively correlated with urine deoxypyridinoline (r = 0.353, p < 0.05). GDF-9 did not correlate with bone markers and BMD measurements. In conclusion, plasma GDF-9 and GDF-15 levels as well as bone turnover markers and BMD measurements in subjects with PCOS (25-35 years of age) were comparable with those either in subjects with IH or in healthy controls with similar anthropometric and metabolic profiles. GDF-15 might be a marker of a crossregulation between bone and energy metabolism.

RESUMO

PURPOSE: To evaluate the association of idiopathic hirsutism, insulin resistance and metabolic disorders. METHODS: Participants of this study included 137 women with idiopathic hirsutism and 698 women as controls selected from two large population-based cross-sectional studies including 1,772 reproductive-aged women. Anthropometric and biochemical characteristics of the participants were measured and compared; for instance, insulin resistance was estimated through the homeostatic model assessment and the metabolic syndrome was detected using the Joint Interim Statement. RESULTS: Mean age, body mass index and other anthropometric measures including waist and hip circumferences were statistically higher in women with idiopathic hirsutism. No differences were observed in blood pressure, glucose and lipid profiles, homeostatic model assessment or the prevalence of insulin resistance, obesity and metabolic syndrome in women with idiopathic hirsutism and controls after adjustment of age and body mass index. In the subgroup of women with metabolic syndrome, fasting glucose levels of those with idiopathic hirsutism were significantly higher than controls, after adjustment of age and body mass index as 114 ± 25.85 vs. 103.52 ± 41.90 mg/dL, P = 0.003. Furthermore, the age and body mass index-adjusted prevalence of impaired fasting glucose in women with idiopathic hirsutism were higher than controls as 16.8 vs. 4.6%, OR = 2.26, 95% CI 1.59-5.38. A threshold of 74.5 cm for waist circumference had the optimal combined sensitivity and specificity for prediction of insulin resistance in women with idiopathic hirsutism, though this value was 90.5 cm for controls. CONCLUSIONS: Our data suggest that although the overall metabolic characteristics were similar in women with idiopathic hirsutism and controls, glycemic disturbances were more often seen in those suffered from metabolic syndrome and idiopathic hirsutism simultaneously.

RESUMO

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.

RESUMO

BACKGROUND & AIMS: Polycystic ovary syndrome (PCOS) is characterized by ovarian dysfunction and hyperandrogenism and by insulin resistance and related metabolic alterations. Both metformin and anti-androgens, such as spironolactone, are used to ameliorate the different aspects of this disorder. We investigated whether therapy with metformin plus low-dose spironolactone is more effective than metformin alone in PCOS patients. METHODS AND RESULTS: Fifty-six PCOS patients were randomized in two groups: group A (28 patients) was treated with metformin (1700 mg/die) and group B (28 patients) was treated with metformin (1700 mg/die) plus low-dose spironolactone (25 mg/die). Anthropometric, hormonal and metabolic parameters were evaluated at baseline and after six months of treatment. After therapy regular menses were restored in approximately 82% of group A patients (P < 0.001) and in 68% of group B patients (P < 0.001). Circulating testosterone, Δ-4-androstenedione and Hirsutism Score (HS) significantly decreased in both groups. However, dehydro-epiandrosterone sulphate significantly decreased only in group B, and HS underwent a stronger reduction in group B (P < 0.001). At baseline, 39/56 (69.6%) patients met the diagnostic criteria for metabolic syndrome, but only one patient met these criteria after treatment. CONCLUSIONS: This study confirms the beneficial effects of metformin in PCOS patients. It also indicates that the addition of low-dose spironolactone induces a more marked reduction of clinical and biochemical hyperandrogenism as compared to metformin alone.

RESUMO

BACKGROUND: The complex correlation between ethnicity and race, clinical hyperandrogenism as signified by hirsutism, and biochemical androgen concentrations in polycystic ovary syndrome (PCOS) is poorly understood. STUDY OBJECTIVE: The aim of this study was to define the correlation between ethnicity/race and hirsutism score in patients with PCOS. METHODS: We conducted a retrospective chart review of a total of 251 patients with PCOS at the time of diagnosis. Patients were categorized by their ethnicity and race into 5 main groups: Asian (n = 19, 7.6%), Black or African American (n = 11, 4.4%), Hispanic or Latino (n = 26, 10.3%), White (n = 177, 70.5), and others (n = 18, 7.2%). A general linear model was applied using BlueSky software. RESULTS: For the entire study population, the mean age at diagnosis was 15.6 ± 1.7, the mean body mass index (BMI) was 30.6 ± 9.8, the mean hirsutism score using the modified Ferriman-Gallwey score chart was 6.2 ± 3.8, and the mean total testosterone was 40.1 ± 20. The hirsutism score was the highest in the Asian population (mean = 9.1, P = .002) and Hispanic or Latino population (mean = 7.8, P = .02), followed by others (mean = 7.4, P = .04) and the Black or African American population (mean = 7.1, P = .2), compared with the White population (mean = 5.4). This correlation remained significant despite accounting for BMI and androgen levels (P < .001). CONCLUSION: There are factors likely related to hair follicle sensitivity or endogenous response to circulating free androgens that differ between ethnicities and races, such that similar biochemical concentrations lead to differing severity of hirsutism, despite accounting for differences in BMI and androgen levels. More research is needed in this realm to understand the pathophysiologic basis of this interaction.

RESUMO

There is a strong correlation between the severity of genotypes and 17OH-progesterone levels in patients with the nonclassical form of 21-hydroxylase deficiency (NC-CAH); however, there are few studies regarding the correlation with clinical signs. The aim of the study was to evaluate whether genotypes correlate with the severity of the hyperandrogenic phenotype. A cohort of 114 NC-CAH patients were diagnosed by stimulated-17OHP ≥10 ng/ml. CYP21A2 genotypes were divided into 2 groups according to the severity of enzymatic impairment; mild and severe. Clinical data and hormonal profiles were compared between the 2 groups. Age at onset of manifestations did not differ between children or adults carrying both mild and severe genotypes. Frequencies of precocious pubarche and hirsutism, with or without menstrual abnormalities, were similar between the 2 groups. There were no differences in basal testosterone levels of adult symptomatic females carrying both genotypes, but there were differences between adult females with (92.9±49.5 ng/dl) and without hirsutism (43.8±38 ng/dl) (p=0.0002). Similar frequencies of both genotypes were observed in asymptomatic females and in those with clitoromegaly. Nonclassical genotypes do not predict the severity of phenotype. Asymptomatic and virilized females carrying the same genotype suggest that there is a modulatory effect of genes involved in the androgen pathway on the phenotype.

RESUMO

OBJECTIVE: To study growth of facial and body terminal hair of women in Guangdong province and its relationship with age, menstrual irregularities and polycystic ovary, and determine normative cut-off score of modified Ferriman and Gallwey (mFG). METHODS: A cross-sectional study was conducted on 2988 women at age of 20-45 years from 16 communities of two urban and two rural regions in Guangdong province from June 2008 to July 2009. Terminal body hair growth was assessed by using the modified Ferriman and Gallwey (mFG) scoring system. The normative cut-off value of mFG were calculated by using the K-means cluster analysis (K=2). Those women were classified into following groups, including 982 women at group of ages of 20- years, 765 women at group of 26- years, 597 women at group of 31- years, 384 women at group of 36- years, 260 women at group of 41-45 years. Due to absence or errors of medical records, some cases were excluded from this study. Based on menses irregularities (MI), polycystic ovaries (PCO), there were 488 cases in MI group, 2413 cases in normal menses group, 568 cases in PCO group, and 2207 cases in non-PCO group finally. The incidences of acne, MI, acanthosis nigricans, and polycystic ovaries were also analyzed in all the hirsute groups. RESULTS: (1) among 2988 women, it was observed 149 women (5%) with mFG≥7,314 women (10.5%) with ≥5,747 women with mFG≥2. (2) Cluster analysis identified an mFG score of 5 as the cut-off value that define abnormal hirsute in the total population and all the sub-groups with/without MI or PCO; (3) Based on age classification, it was found that increased age was associated with decreased trends of the percentile and cut-off value of hirsutism. The value of hirsutism of mFG were 6 in group of 20- years, 5 in group of 26- years, 4 in groups of 31- years, 36- years and 41-45 years. (4) The prevalence of acne, menstrual irregularities and POC were 45.5% (143/314), 73.6% (231/314), 25.8% (81/314) in total population, 25.1% (671/2674), 16.1% (431/2674), 19.8% (529/2674) in normal hair women, which reached statistical difference (P<0.05). The prevalence of acne, menstrual irregularities and acanthosis nigricans were 44.4% (130/293), 23.2% (68/293), 4.1% (12/293) in those age hirsute groups, 25.3% (681/2695), 16.2% (437/2695), 1.9% (51/2695) in normal hair women, which reached statistical difference (P<0.05). CONCLUSIONS: (1) among women in Guangdong province, mFG scoring showed decreased trends in women with increasing age. (2) An mFG score≥5 was cut-off value in diagnosis of hirsutism. (3) The hirsute women exhibited higher incidence of acne, menses irregularity, and acanthosis nigricans than those of women with normal hair growth.

RESUMO

BACKGROUND: The polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women. On the contrary, the prevalences of other disorders of androgen excess such as idiopathic hyperandrogenism and idiopathic hirsutism remain unknown. We aimed to obtain an unbiased estimate of the prevalence in premenopausal women of (i) signs of androgen excess and (ii) PCOS, idiopathic hyperandrogenism and idiopathic hirsutism. METHODS: A multicenter prevalence survey included 592 consecutive premenopausal women (393 from Madrid, Spain and 199 from Bologna, Italy) reporting spontaneously for blood donation. Immediately before donation, we conducted clinical and biochemical phenotyping for androgen excess disorders. We determined the prevalence of (i) hirsutism, acne and alopecia as clinical signs of androgen excess and (ii) functional disorders of androgen excess, including PCOS, defined by the National Institute of Child Health and Human Development/National Institute of Health criteria, idiopathic hyperandrogenism and idiopathic hirsutism. RESULTS: Regarding clinical signs of hyperandrogenism, hirsutism and acne were equally frequent [12.2% prevalence; 95% confidence interval (CI): 9.5-14.8%], whereas alopecia was uncommon (1.7% prevalence, 95% CI: 0.7-2.7%). Regarding functional disorders of androgen excess, PCOS and idiopathic hirsutism were equally frequent (5.4% prevalence, 95% CI: 3.6-7.2) followed by idiopathic hyperandrogenism (3.9% prevalence, 95% CI: 2.3-5.4). CONCLUSIONS: Clinical signs of hyperandrogenism and functional disorders of androgen excess show a high prevalence in premenopausal women. The prevalences of idiopathic hyperandrogenism and idiopathic hirsutism are similar to that of PCOS, highlighting the need for further research on the pathophysiology, consequences for health and clinical implications of these functional forms of androgen excess.

RESUMO

AIMS: To assess whether a single nucleotide polymorphism (SNP50) of the aromatase gene (CYP19) is associated with polycystic ovary syndrome (PCOS) phenotypes and to investigate the influence of this polymorphism on the response of PCOS to treatment with oral contraceptive pills (OCP). METHODS: 162 hirsute women were stratified into a classic PCOS group (hyperandrogenism, ovulatory dysfunction, c-PCOS) and an ovulatory PCOS group (hyperandrogenism, ovulatory cycles, polycystic ovaries, ov-PCOS). 51 women completed a 6-month OCP trial (20 µg ethinyl estradiol + 75 µg gestodene, 21/28 days per cycle, plus 100 mg spironolactone in 32 women with moderate to severe hirsutism). We considered the presence of the polymorphic allele A (AG+AA) in comparison to the absence of the polymorphism (GG) to express results and to perform the comparisons regarding clinical variables. RESULTS: Mean age was 23.3 ± 6.9 years. Hirsutism score was similar in c-PCOS and ov-PCOS (15 (11-20) vs. 13 (11-20)). The differences in hormone and metabolic variables between phenotypes were independent of the presence of allele A. In the OCP trial subsample, no differences were observed between genotypes after 6 months' treatment. CONCLUSION: The differences between c-PCOS and ov-PCOS cannot be explained by the genetic variation at SNP50 in the CYP19 gene.
