Comparison of finasteride versus spironolactone in the treatment of idiopathic hirsutism

Objective: To compare the efficacy of finasteride and spironolactone in the treatment of idiopathic hirsutism.

Design: Prospective, randomized, single-blind study.

Setting: A tertiary hirsutism clinic.

Patient(s): Forty women with idiopathic hirsutism were selected.

Intervention(s): Patients were assigned randomly to receive either 5 mg of finasteride or 100 mg of spironolactone for 9 months.

Main Outcome Measure(s): Hirsutism scores were measured according to the Ferriman-Gallwey scoring system, and side effects were monitored for 9 months of treatment. Blood samples were taken at each visit for assessment of endocrine, biochemical, and hematologic parameters.

Result(s): Hirsutism scores were decreased significantly in both groups at the end of 9 months. The mean percent change (±SD) in hirsutism scores in the finasteride and spironolactone groups was as follows: 5.91% ± 7.18% and 20.60% ± 12.59% at 3 months, 10.61% ± 12.18% and 32.57% ± 15.68% at 6 months, and 15.15% ± 15.38% and 42.36% ± 12.31% at 9 months, respectively. There was a significantly better response with spironolactone treatment at the end of 9 months. Eleven (55%) of 20 patients in the spironolactone group experienced side effects. However, none of them stopped treatment because of side effects.

Conclusion(s): The present data suggest that both finasteride and spironolactone are effective in the treatment of idiopathic hirsutism. However, it appears that the spironolactone group responded significantly better.     

Epidemiologic and etiologic aspects of hirsutism in Kashmiri women in the Indian subcontinent

OBJECTIVE: To assess the prevalence of hirsutism and study its etiology in the Kashmir Valley of the Indian subcontinent. DESIGN: Prospective random sample of the general population attending outpatient medical clinics and prospective evaluation of hirsute patients referred to our endocrinology clinic. SETTING: A tertiary care hospital and district-level primary care hospitals. PATIENT(S): Five thousand women attending various hospitals for reasons unrelated to hirsutism and 150 consecutive women referred for hirsutism. INTERVENTION(S): Assessment of body hair as per the Ferriman and Gallwey scoring system and an investigative protocol including detailed clinical assessment with endocrinologic workup including estimations of gonadotropins, PRL, T, and 17-hydroxyprogesterone and abdominopelvic ultrasound. MAIN OUTCOME MEASURE(S): Presence and cause of hirsutism. RESULT(S): Of 4,780 adult women for whom adequate data were available, 504 (10.5%) had hirsutism, among whom 484 (10.1%) had mild (score of 6-9) and 20 (0.4%) had moderate hirsutism (score of 10-14). The etiology of hirsutism revealed idiopathic hirsutism in 38.7%, polycystic ovary syndrome (PCOS) in 37.3%, postmenopausal state in 9.2%, adrenal tumors in 2.1%, congenital adrenal hyperplasia in 1.4%, and drug-induced hirsutism in 0.7%. The cause remained undetermined in 10.6% of patients for whom the available information was not adequate. CONCLUSION(S): Hirsutism is as common a problem in the Kashmir Valley (India) as elsewhere in the world. Idiopathic hirsutism (38.7%), PCOS (37.3%), and postmenopausal state (9.2%) are common causes of hirsutism. Late-onset congenital adrenal hyperplasia is a relatively uncommon cause of hirsutism in the Kashmir Valley.     

Should insulin resistance be screened in lean hirsute women?

Abstract

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/m², 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.     

Observation of phenotypic variation among Indian women with polycystic ovary syndrome (PCOS) from Delhi and Srinagar

Polycystic ovary syndrome (PCOS) is a heterogeneous disorder that demonstrates ethnic and regional differences. To assess the phenotypic variability among Indian PCOS women, we evaluated clinical, biochemical and hormonal parameters of these women being followed in two tertiary care institutions located in Delhi and Srinagar. A total of 299 (210 PCOS diagnosed by Rotterdam 2003 criteria and 89 healthy) women underwent estimation of T4, TSH, LH, FSH, total testosterone, prolactin, cortisol, 17OHP, and lipid profile, in addition to post OGTT, C-peptide, insulin, and glucose measurements. Among women with PCOS, mean age, age of menarche, height, systolic, diastolic blood pressure, and serum LH were comparable. PCOS women from Delhi had significantly higher BMI (26.99?±?5.38 versus 24.77?±?4.32?kg/m²; P?=?0.01), glucose intolerance (36 versus 10%), insulin resistance as measured by HOMA-IR (4.20?±?3.39 versus 3.01?±?2.6; P?=?0.006) and QUICKI (0.140?±?0.013 versus 0.147?±?0.015; P?=?0.03) while PCOS from Srinagar had higher FG score (12.12?±?3.91 versus 10.32?±?2.22; P?=?0.01) and serum total testosterone levels (0.65?±?0.69 versus 0.86?±?0.41?ng/ml; P?=?0.01. Two clear phenotypes, i.e. obese hyperinsulinaemic dysglycemic women from Delhi and lean hyperandrogenic women from Srinagar are emerging. This is the first report on North Indian women with PCOS showing phenotypic differences in clinical, biochemical and hormonal parameters despite being in the same region.     

CAPN10 UCSNP-43, UCSNP-19 and UCSNP-63 polymorphisms and metabolic syndrome in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder with individual susceptibility determined by genetic and environmental risk factors. Recently, studies have evaluated the CAPN10 gene in PCOS patients, suggesting that different alleles may play a role in PCOS susceptibility. We performed a cross-sectional study with 88 southern Brazilian hirsute patients with PCOS or idiopathic hirsutism (IH) to assess the influence of CAPN10 genetic variants on clinical and biochemical features of metabolic syndrome. PCOS patients were defined by oligo/amenorrheic cycles (<9 cycles/year), increased levels of serum testosterone and/or free androgen index, and exclusion of other disorders associated with hyperandrogenism. IH was diagnosed in hirsute patients with regular ovulatory cycles (luteal-phase progesterone levels >3.8 ng/ml), normal androgen levels, and without any known underlying disease (n = 29). Metabolic syndrome was defined according to the 2001 criteria of the National Cholesterol Education Program, Adult Treatment Panel III. UCSNP-43 polymorphism of CAPN10 was related to metabolic syndrome (p = 0.047) in PCOS; UCSNP-19 and UCSNP-63 were not associated with phenotypic traits in PCOS. These results provide evidence that CAPN10 gene UCSNP-43 polymorphisms may influence the PCOS metabolic phenotype. This should be further confirmed in large population-based studies.     

Morning plasma cortisol is low among obese women with polycystic ovary syndrome

Abstract

Polycystic ovary syndrome (PCOS) is the most common cause for androgen excess in women. It is associated with wide variety of metabolic disorders. The present study assessed morning plasma cortisol in women with PCOS. One hundred and ninety seven cases and 55 controls were enrolled for this study. The mean age of patients and controls were 23?±?5.6 years and 25?±?4.3 years. One hundred twelve (56%) women with PCOS had BMI >25. Serum cortisol levels were significantly higher in lean PCOS women compared to controls (13.4?±?5.1 versus 11.3?±?4.5, p?<?0.01) and over-weight PCOS women group (13.4?±?5.1 versus 9.3?±?3.2, p?<?0.01). There was a trend for less acne and hirsutism with increase in BMI. Morning plasma cortisol was lower among obese women with PCOS. Morning plasma cortisol correlated negatively with BMI in PCOS women with normal glucose tolerance.     

Ultrasound diagnosis of polycystic ovaries in women who have no symptoms of polycystic ovary syndrome is not associated with subfecundity or subfertility

OBJECTIVE: To evaluate the effect on fertility of the appearance of polycystic ovaries in women who have no symptoms of polycystic ovary syndrome. DESIGN: Case-control study. SETTING: Teaching hospitals in Hull, United Kingdom. PATIENT(S): Women with the appearance of polycystic ovaries on ultrasound and women with normal ovaries. INTERVENTION(S): A questionnaire about previous subfertility, pregnancies, menstrual pattern, features of polycystic ovary syndrome, gynecological history, and individual lifestyle factors. MAIN OUTCOME MEASURE(S): Time to pregnancy (TTP) and relative risk (RR) of subfertility in symptomatic and asymptomatic subgroups of both groups. RESULT(S): Women with PCOs took longer TTP and were significantly less fertile if they were obese (RR = 2.6), had menstrual disturbances (RR = 4.6), hirsutism (RR = 2.5), and/or acne (RR = 2.7). Further reductions in fecundity occurred with an increasing number of symptoms (threefold, sevenfold, and 10-fold longer TTP with two, three, and four symptoms, respectively). The TTP of women with no symptoms was not significantly longer and they were not more likely to be subfertile than women with normal ovaries. These symptoms were not associated with significantly reduced fecundity in women with normal ovaries. CONCLUSION(S): The appearance of polycystic ovaries has been shown to have no significant impact on fertility in women with no symptoms. Appearances alone do not reflect the pathological features of polycystic ovary syndrome, and additional diagnostic criteria should be considered. Obesity, menstrual disturbances, and/or hyperandrogenism are factors associated with subfertility in women with polycystic ovaries.     

Effects of low-dose metformin in Japanese women with clomiphene-resistant polycystic ovary syndrome

Background and Aims  The aim of the present prospective observational study was to evaluate the effects of low-dose, short-term metformin, in combination with domiphene (CC), in CC-resistant infertile Japanese women with polycystic ovary syndrome (PCOS). Methods  Metformin therapy was administered orally (one 250 mg tablet, twice daily) to 15 CC-resistant infertile patients with PCOS, beginning on the third day of progestin-induced withdrawal bleeding, and was continued for 14 days in the first cycle. In the event of anovulation, 100 mg/day of CC was given during subsequent cycles on days 5–9, in addition to the aforementioned dose of metformin. Hormonal and metabolic parameters were measured on the second or third days of the first cycle and also the fourth cycle, following an overnight fast. Results  None of the 15 women successfully ovulated during the first cycle with metformin treatment alone. After two subsequent cycles with the combination of CC and metformin, ovulation was confirmed in 17 of 29 cycles (61%) and in 13 of 15 patients (87%). Two women became pregnant within 2 months of therapy (13%). There were no cases of ovarian hyperstimulation syndrome. Following three cycles of metformin therapy, a slight reduction in serum levels of luteinizing hormone (LH), free testosterone, androstenedione, dehydroepiandrosterone sulfate, hemoglobin Alc and total cholesterol was seen, while serum LH/follide-stimulating hormone ratio and serum level of low-density lipoprotein cholesterol were significantly decreased. Although there were no significant differences between the responder (n = 11) and non-responder (n = 2) groups at baseline, the levels of plasma fasting insulin was significantly higher and fasting glucose/insulin ratio was significantly lower in the non-responder group compared with the responder group after three cycles. Conclusion  Low-dose, short-term metformin, combined with CC, can improve ovulation rates in CC-resistant infertile Japanese women with PCOS.     

Contraceptive choices for women with endocrine complications

Previous confusion regarding the interference by oral contraceptives in measurements of endocrine function have been largely eliminated by the advent of improved, more sensitive assays. There are few if any contraindications to oral contraceptive use in patients with thyroid disease. Patients with prolactinoma can be treated with bromocriptine to restore fertility and prevent mineral loss. However, as a less expensive alternative, oral contraceptives can be prescribed to correct mineral loss, because there is no convincing evidence of an adverse effect on prolactinomas by the steroidal content of the pill. Oral contraceptives comprise a near ideal treatment modality for women with polycystic ovary disease because, among other effects, oral contraceptives reduce synthesis of androgen by inhibiting pituitary gonadotropin secretion.

Serum adiponectin is independently associated with the metabolic syndrome in Hong Kong,Chinese women with polycystic ovary syndrome

Objective: To evaluate the association of serum adiponectin level with the metabolic syndrome in Chinese women with polycystic ovary syndrome (PCOS).

Methods: This was a cross-sectional study carried out in Hong Kong Chinese women with PCOS at a university-affiliated tertiary hospital between January 2010 and January 2011. Clinical and biochemical parameters of the women were analysed. Prediction of the metabolic syndrome was determined by receiver–operator characteristic (ROC) curves, univariate and multivariate logistic regression analyses.

Results: A total of 116 women diagnosed to have PCOS were analysed. The area under the ROC curve of adiponectin for the prediction of metabolic syndrome was 0.820, 95% confidence interval (CI) 0.737–0.886. Univariate binary logistic regression showed that testosterone, sex hormone-binding globulin (SHBG), free androgen index (FAI), waist circumference, body mass index (BMI), quantitative insulin-sensitivity check index (QUICKI), homeostasis model assessment of insulin resistance (HOMA-IR) and adiponectin were significantly associated with the metabolic syndrome. On multivariate logistic regression analysis, adiponectin (p?= 0.020), HOMA-IR, age (p?= 0.011) and BMI (p?= 0.019) were independently associated with the metabolic syndrome, but not FAI (p?= 0.256).

Conclusions: Serum adiponectin is independently associated with the metabolic syndrome in Chinese women with PCOS. Further longitudinal follow-up studies are needed to determine whether serum adiponectin adds to the prediction of long-term cardiometabolic morbidity conferred by age, BMI and measures of insulin resistance.     

Low birth-weight is a PCOS risk factor for Southern-Italian women

Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine and metabolic disorder, characterized by chronic anovulation/oligomenorrhea, hyperandrogenism and insulin-resistance. Initial studies on the genetic basis of this disorder suggested both a maternal and paternal pattern of inheritance. Birth weight has become a main factor to consider when investigating the etiology of an adult-onset disease, since it is a simple indicator of intrauterine adverse conditions. The aim of our study is to validate the “low birth-weight” as risk factor for the development of PCOS. We performed a retrospective study on 188 PCOS patients and 185 controls, showing that Southern-Italian PCOS population have a significant lower birth-weight comparing to the control population; interestingly, PCOS women with low and normal low weight at birth show higher levels of androgens. Taken together, our result highlights the importance of the “birth-weight” factor for PCOS anamnesis.     

A low-dose stimulation protocol using highly purified follicle-stimulating hormone can lead to high pregnancy rates in in vitro fertilization patients with polycystic ovaries who are at risk of a high ovarian response to gonadotropins

Objective: To study the benefits of a low-dose stimulation (LDS) protocol with purified urinary follicle-stimulating hormone in patients with polycystic ovaries who have presented previously with a very high ovarian response to a standard hMG stimulation.

Design: Cohort study.

Setting: Fertility center in a university hospital.

Patient(s): Sixty-one patients involved in an IVF/ICSI program from January 1995 to December 1996.

Intervention(s): The patients were first stimulated with a standard protocol using hMG and presented with a very high ovarian response. These patients were then stimulated a second time using a low-dose protocol. Cryopreserved embryos were transferred in later artificial or natural cycles until to December 1999.

Main Outcome Measure(s): Number of gonadotropin ampules; estradiol level on the day of ovulation induction; follicles, oocytes, and cryopreserved zygotes; fertilization, implantation, and pregnancy rates; and number of ovarian hyperstimulation syndromes (OHSS).

Result(s): The number of ampules used, the estradiol level reached, and the number of oocytes obtained were significantly lower under the LDS than the standard protocol. High implantation (21.8%) and clinical pregnancy (38.4%) rates were obtained after LDS. The cumulated deliveries per cycle started and per patient were, respectively, 41.6% and 52.5%. Five patients suffered OHSS with the standard protocol, and none with the LDS.

Conclusion(s): The LDS protocol offers a safe and efficient treatment for patients who present with echographic polycystic ovaries and are at risk of an excessive ovarian response to standard IVF stimulation protocols.     

Effects of combined oral contraceptives on the clinical and biochemical parameters of hyperandrogenism in patients with polycystic ovary syndrome: a systematic review and meta-analysis

Introduction: Nowadays, selection of COCs with maximum antiandrogenic effects is one the main issues in treatment of women with polycystic ovary syndrome (PCOS).

Objective: This systematic review and meta-analysis aimed to compare the effects of COCs on the clinical and biochemical parameters of hyperandrogenism (HA) in patients with PCOS.

Methods: Electronic databases (PubMed, Scopus, ScienceDirect and web of science) were searched from 1987 to November 2015 to identify clinical trials investigating effect of the various COCs on the clinical and biochemical parameters of HA in patients. In this meta-analysis, both fixed and random effect models were used. Potential sources of heterogeneity were explored by meta-regression and subgroup analyses.

Results: Findings showed that COC use for 3–12 months was significantly associated with an increase in sex hormone-binding globulin (SHBG) levels and a decrease in Ferriman–Gallwey (FG) score, total testosterone (TT), free testosterone (FT), androstenedione (A4) and dehydroepiandrosterone sulphate (DHEAS) levels. Type of progestin or duration of treatment had no important effects on declining androgen levels. Long-term use of COCs (6–12 months) was more effective in improving hirsutism, compared to short term. COCs containing cyproterone acetate (CPA) for 12 months had the strongest effect in improving hirsutism.

Conclusions: This study shows that, in patients with PCOS, COCs can effectively improve biochemical and clinical parameters of HA. All COCs studies have similar effects on the hormonal profiles of these patients, and products containing CPA may be an effective treatment in hirsute patients with PCOS.

目的探讨多囊卵巢综合征（PCOS）患者血清一氧化氮（NO）水平与其血管并发症的关系。方法采用硝酸还原酶法测定27例PCOS患者（PCOS组）,21例因男方因素或输卵管因素不孕患者（对照组）血清NO水平,测定并计算体重指数（BMI）、腰臀比（WHR）、收缩压（SBP）、舒张压（DBP）、体脂含量、胰岛素抵抗指数（HOMA-IR）、胰岛素敏感指数（IAI）、血清性激素、空腹血糖（FPG）和胰岛素（FINS）水平。结果非肥胖PCOS组的HOMA-IR高于非肥胖对照组,IAI、血清NO水平低于非肥胖对照组,差异均有显著性（P〈0.05）。非肥胖PCOS组IAI明显高于肥胖PCOS组,差异有显著性（P〈0.01）。血清NO水平在PCOS组和其对照组间差异无显著性（P〉0.05）。PCOS组中,血清NO水平与HOMA-IR（r=-0.317,P〈0.05）、体脂含量（r=-0.346,P〈0.05）呈负相关。结论PCOS患者血清NO水平降低,提示PCOS患者可能存在血管内皮功能受损。     

Insulin gene variable number of tandem repeats regulatory polymorphism is not associated with hyperandrogenism in Spanish women

OBJECTIVE: To determine if the insulin gene variable number of tandem repeats (VNTR) regulatory polymorphism is associated with hyperandrogenism in a population of Spanish women. DESIGN: Controlled clinical study. SETTING: Tertiary institutional hospital. PATIENT(S): Ninety-six hyperandrogenic patients and 38 healthy control women. INTERVENTION(S): Whole blood and serum samples were collected during the follicular phase of the menstrual cycle. MAIN OUTCOME MEASURE(S): Insulin gene VNTR regulatory polymorphism genotypes (classes I/I, I/III, and III/III alleles) and serum androgen levels. Insulin resistance was estimated from fasting glucose and insulin levels by using the homeostatic model assessment. RESULT(S): The frequencies of VNTR genotypes were 45.5%, 43.3%, and 11.2% for I/I, I/III, and III/III alleles considering patients and controls as a whole. These frequencies were not statistically different in controls (47.4%, 34.2%, and 18.4%) and in patients (44.8%, 46.9%, and 8.3%). CONCLUSION(S): Hyperandrogenism and the insulin gene VNTR regulatory polymorphism are not associated in Spanish women.
