Long-term efficacy and tolerability of flutamide combined with oral contraception in moderate to severe hirsutism: a 12-month, double-blind, parallel clinical trial

The effects of conformation and intermolecular hydrogen bonding on the structure and IR spectra of flutamide; a study based on the matrix isolation technique, ab initio and DFT calculations

In this study, stable conformers of flutamide referred to as an anticancer drug were searched through a relaxed potential energy surface scan carried out at the B3LYP/6-31G(d) level of theory. This was followed by geometry optimization and thermochemistry calculations performed with the HF-SCF, MP2, B3LYP methods and the 6-31G(d), 6-311++G(d,p), aug-cc-pvTZ basis sets for each of the determined minimum energy conformers. The results revealed that flutamide has at least five stable conformers and two of them provide the major contribution to the observed matrix isolation infrared (IR) spectra of the molecule. The effects of conformational variety and intermolecular hydrogen bonding interactions on the observed IR spectra of flutamide were interpreted in the light of the vibrational spectral data obtained for the most stable monomer and dimer forms of the molecule at the same levels of theory. Pulay's "Scaled Quantum Mechanical-Force Field (SQM-FF)" method was used in the refinement of the calculated harmonic wavenumbers, IR intensities and potential energy distributions. This scaling method which proved its superiority to both anharmonic frequency calculations and other scaling methods helped us to correctly interpret the remarkable differences between the matrix IR spectra of flutamide in argon and the condensed phase IR spectra of the molecule in solvents such as KBr, H₂O, D₂O, ethanol and methanol.

Polycystic Ovary Syndrome: Etiology, Current Management, and Future Therapeutics

Polycystic ovary syndrome (PCOS) is a complex endocrine and metabolic disorder, typically characterized by anovulation, infertility, obesity, insulin resistance, and polycystic ovaries. Lifestyle or diet, environmental pollutants, genetics, gut dysbiosis, neuroendocrine alterations, and obesity are among the risk factors that predispose females to PCOS. These factors might contribute to upsurging metabolic syndrome by causing hyperinsulinemia, oxidative stress, hyperandrogenism, impaired folliculogenesis, and irregular menstrual cycles. Dysbiosis of gut microbiota may play a pathogenic role in the development of PCOS. The restoration of gut microbiota by probiotics, prebiotics, or a fecal microbiota transplant (FMT) might serve as an innovative, efficient, and noninvasive way to prevent and mitigate PCOS. This review deliberates on the variety of risk factors potentially involved in the etiology, prevalence, and modulation of PCOS, in addition to plausible therapeutic interventions, including miRNA therapy and the eubiosis of gut microbiota, that may help treat and manage PCOS.

Randomized clinical trial: effect of low-dose flutamide on abdominal adipogenic function in normal-weight women with polycystic ovary syndrome

OBJECTIVE

To examine whether low-dose flutamide administration to normal-weight women with polycystic ovary syndrome (PCOS) reduces abdominal fat deposition, attenuates accelerated lipid accumulation in newly formed adipocytes derived from subcutaneous (SC) abdominal adipose stem cells (ASCs), and/or alters glucose-lipid metabolism.

DESIGN

A double-blind, placebo-controlled randomized clinical trial.

SETTING

An academic medical center.

PATIENT(S)

Twelve normal-weight women with PCOS and 12 age- and body mass index-matched controls.

INTERVENTION(S)

Women underwent circulating hormonal and metabolic determinations, intravenous glucose tolerance testing, total body dual-energy roentgenogram absorptiometry, and SC abdominal fat biopsy. Interventions were repeated in women with PCOS after 6-month administration of flutamide (125 mg orally daily) vs. placebo.

MAIN OUTCOME MEASURE(S)

Clinical parameters and lipid accumulation in newly formed adipocytes derived from SC abdominal ASCs in vitro were compared between controls and the women with PCOS receiving flutamide vs. placebo.

RESULTS

Serum luteinizing hormone and androgen levels as well as lipid accumulation in newly formed SC abdominal adipocytes were greater in the women with PCOS than controls. Flutamide vs. placebo reduced percent android fat, lowered serum log low-density lipoprotein and log non-high-density lipoprotein levels, and increased fasting circulating glucose levels. In all women with PCOS, changes in percent android fat positively correlated with serum log non-high-density lipoprotein and log low-density lipoprotein levels, with correlations influenced by serum free testosterone levels. Flutamide vs. placebo also attenuated lipid accumulation in newly-formed PCOS SC abdominal adipocytes in vitro relative to controls, which was unrelated to serum lipid levels.

CONCLUSION

Low-dose flutamide administration to normal-weight PCOS women reduces preferential abdominal fat deposition, attenuates accelerated lipid accumulation in newly-formed adipocytes derived from SC abdominal ASCs in vitro, and alters glucose-lipid homeostasis.

Androgen-mediated Perturbation of the Hepatic Circadian System Through Epigenetic Modulation Promotes NAFLD in PCOS Mice

In women, excess androgen causes polycystic ovary syndrome (PCOS), a common fertility disorder with comorbid metabolic dysfunctions including diabetes, obesity, and nonalcoholic fatty liver disease. Using a PCOS mouse model, this study shows that chronic high androgen levels cause hepatic steatosis while hepatocyte-specific androgen receptor (AR)-knockout rescues this phenotype. Moreover, through RNA-sequencing and metabolomic studies, we have identified key metabolic genes and pathways affected by hyperandrogenism. Our studies reveal that a large number of metabolic genes are directly regulated by androgens through AR binding to androgen response element sequences on the promoter region of these genes. Interestingly, a number of circadian genes are also differentially regulated by androgens. In vivo and in vitro studies using a circadian reporter [Period2::Luciferase (Per2::LUC)] mouse model demonstrate that androgens can directly disrupt the hepatic timing system, which is a key regulator of liver metabolism. Consequently, studies show that androgens decrease H3K27me3, a gene silencing mark on the promoter of core clock genes, by inhibiting the expression of histone methyltransferase, Ezh2, while inducing the expression of the histone demethylase, JMJD3, which is responsible for adding and removing the H3K27me3 mark, respectively. Finally, we report that under hyperandrogenic conditions, some of the same circadian/metabolic genes that are upregulated in the mouse liver are also elevated in nonhuman primate livers. In summary, these studies not only provide an overall understanding of how hyperandrogenism associated with PCOS affects liver gene expression and metabolism but also offer insight into the underlying mechanisms leading to hepatic steatosis in PCOS.

Key signalling pathways underlying the aetiology of polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine condition characterised by a range of reproductive, endocrine, metabolic and psychological abnormalities. Reports estimate that around 10% of women of reproductive age are affected by PCOS, representing a significant prevalence worldwide, which poses a high economic health burden. As the origin of PCOS remains largely unknown, there is neither a cure nor mechanism-based treatments leaving patient management suboptimal and focused solely on symptomatic treatment. However, if the underlying mechanisms underpinning the development of PCOS were uncovered then this would pave the way for the development of new interventions for PCOS. Recently, there have been significant advances in our understanding of the underlying pathways likely involved in PCOS pathogenesis. Key insights include the potential involvement of androgens, insulin, anti-Müllerian hormone and transforming growth factor beta in the development of PCOS. This review will summarise the significant scientific discoveries on these factors that have enhanced our knowledge of the mechanisms involved in the development of PCOS and discuss the impact these insights may have in shaping the future development of effective strategies for women with PCOS.

Sex Steroid Receptors in Polycystic Ovary Syndrome and Endometriosis: Insights from Laboratory Studies to Clinical Trials

Polycystic ovary syndrome (PCOS) and endometriosis are reproductive disorders that may cause infertility. The pathology of both diseases has been suggested to be associated with sex steroid hormone receptors, including oestrogen receptors (ER), progesterone receptors (PRs) and androgen receptors (ARs). Therefore, with this review, we aim to provide an update on the available knowledge of these receptors and how their interactions contribute to the pathogenesis of PCOS and endometriosis. One of the main PCOS-related medical conditions is abnormal folliculogenesis, which is associated with the downregulation of ER and AR expression in the ovaries. In addition, metabolic disorders in PCOS are caused by dysregulation of sex steroid hormone receptor expression. Furthermore, endometriosis is related to the upregulation of ER and the downregulation of PR expression. These receptors may serve as therapeutic targets for the treatment of PCOS-related disorders and endometriosis, considering their pathophysiological roles. Receptor agonists may be applied to increase the expression of a specific receptor and treat endometriosis or metabolic disorders. In contrast, receptor antagonist functions to reduce receptor expression and can be used to treat endometriosis and induce ovulation. Understanding PCOS and the pathological roles of endometriosis sex steroid receptors is crucial for developing potential therapeutic strategies to treat infertility in both conditions. Therefore, research should be continued to fill the knowledge gap regarding the subject.

Next Generation Risk Assessment of the Anti-Androgen Flutamide Including the Contribution of Its Active Metabolite Hydroxyflutamide

In next generation risk assessment (NGRA), non-animal approaches are used to quantify the chemical concentrations required to trigger bioactivity responses, in order to assure safe levels of human exposure. A limitation of many in vitro bioactivity assays, which are used in an NGRA context as new approach methodologies (NAMs), is that toxicokinetics, including biotransformation, are not adequately captured. The present study aimed to include, as a proof of principle, the bioactivity of the metabolite hydroxyflutamide (HF) in an NGRA approach to evaluate the safety of the anti-androgen flutamide (FLU), using the AR-CALUX assay to derive the NAM point of departure (PoD). The NGRA approach applied also included PBK modelling-facilitated quantitative in vitro to in vivo extrapolation (QIVIVE). The PBK model describing FLU and HF kinetics in humans was developed using GastroPlus™ and validated against human pharmacokinetic data. PBK model-facilitated QIVIVE was performed to translate the in vitro AR-CALUX derived concentration-response data to a corresponding in vivo dose-response curve for the anti-androgenicity of FLU, excluding and including the activity of HF (-HF and +HF, respectively). The in vivo benchmark dose 5% lower confidence limits (BMDL05) derived from the predicted in vivo dose-response curves for FLU, revealed a 440-fold lower BMDL05 when taking the bioactivity of HF into account. Subsequent comparison of the predicted BMDL05 values to the human therapeutic doses and historical animal derived PoDs, revealed that PBK modelling-facilitated QIVIVE that includes the bioactivity of the active metabolite is protective and provides a more appropriate PoD to assure human safety via NGRA, whereas excluding this would potentially result in an underestimation of the risk of FLU exposure in humans.

Female Adult Acne and Androgen Excess: A Report From the Multidisciplinary Androgen Excess and PCOS Committee

In endocrine and reproductive endocrine literature, adult female acne is considered as a possible clinical expression of hyperandrogenism, with most polycystic ovary syndrome (PCOS) guidelines considering acne as a condition of androgen excess. Adult female acne, however, in the dermatological literature is considered as an inflammatory skin disease and new guidelines on adult female acne have been produced by dermatological societies, with little perspective from any endocrine or reproductive endocrine points of view. An expert task force was appointed by the AE-PCOS society to determine the current state of knowledge and provide evidence-based recommendations that could be valid for all specialists taking care of female adult acne. The following are the recommendations (level of evidence A or B): (1) diagnosis of female adult acne is mainly clinical, but a grading tool is needed for optimizing the treatment; (2) measurement of serum androgen values (total testosterone, free testosterone, and dehydroepiandrosterone sulfate) by high-quality assays is recommended in all women with adult acne; (3) in women with adult acne and proven hyperandrogenism, oral combined estroprogestins should be added to the topical or systemic treatment of acne, independently of severity of acne; (4) all second- and third-generation estroprogestins may be used, independently of the estrogen dose and progestin component; (5) spironolactone may be added to estroprogestins in women with moderate or severe hyperandrogenic adult acne, not responding to usual treatments; (6) estroprogestins may be used in nonhyperandrogenic patients with adult acne as second-line therapy.

A safety evaluation of current medications for adult women with the polycystic ovarian syndrome not pursuing pregnancy

INTRODUCTION

The polycystic ovary syndrome (PCOS) is a very prevalent disorder in premenopausal women. Cardiovascular risk factors cluster in these patients, raising concern about the safety of the drugs commonly used to ameliorate symptoms of androgen excess in in this population at risk of cardiovascular morbidity.

AREAS COVERED

This review summarizes the clinical efficacy and safety profiles of drugs commonly used for the management of hyperandrogenic symptoms and endometrial protection in adult women with PCOS who do not seek pregnancy.

EXPERT OPINION

Antiandrogenic drugs usually used in adult women with PCOS carry a low risk of severe side effects. In spite of the cardiovascular risk profile of women with PCOS, and that individualized risk assessment is of paramount importance, there is no solid evidence supporting that the use of combined oral contraceptives in these women increases the risk of cardiovascular or thromboembolic events compared with the general population. However, virtually all these drugs are used in an off-label fashion. Large, high-quality studies addressing the long-term safety of pharmacological treatments in women with PCOS are definitely needed.

The Mechanism of Androgen Actions in PCOS Etiology

Polycystic ovary syndrome (PCOS) is the most common endocrine condition in reproductive-age women. By comprising reproductive, endocrine, metabolic and psychological features—the cause of PCOS is still unknown. Consequently, there is no cure, and management is persistently suboptimal as it depends on the ad hoc management of symptoms only. Recently it has been revealed that androgens have an important role in regulating female fertility. Androgen actions are facilitated via the androgen receptor (AR) and transgenic Ar knockout mouse models have established that AR-mediated androgen actions have a part in regulating female fertility and ovarian function. Considerable evidence from human and animal studies currently reinforces the hypothesis that androgens in excess, working via the AR, play a key role in the origins of polycystic ovary syndrome (PCOS). Identifying and confirming the locations of AR-mediated actions and the molecular mechanisms involved in the development of PCOS is critical to provide the knowledge required for the future development of innovative, mechanism-based interventions for the treatment of PCOS. This review summarises fundamental scientific discoveries that have improved our knowledge of androgen actions in PCOS etiology and how this may form the future development of effective methods to reduce symptoms in patients with PCOS.

Evaluation and Treatment of Hirsutism in Premenopausal Women: An Endocrine Society Clinical Practice Guideline

OBJECTIVE

To update the "Evaluation and Treatment of Hirsutism in Premenopausal Women: An Endocrine Society Clinical Practice Guideline," published by the Endocrine Society in 2008.

PARTICIPANTS

The participants include an Endocrine Society-appointed task force of seven medical experts and a methodologist.

EVIDENCE

This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation system to describe the strength of recommendations and the quality of evidence. The task force commissioned two systematic reviews and used the best available evidence from other published systematic reviews and individual studies.

CONSENSUS PROCESS

Group meetings, conference calls, and e-mail communications facilitated consensus development. Endocrine Society committees, members, and cosponsoring organizations reviewed and commented on preliminary drafts of the guidelines.

CONCLUSION

We suggest testing for elevated androgen levels in all women with an abnormal hirsutism score. We suggest against testing for elevated androgen levels in eumenorrheic women with unwanted local hair growth (i.e., in the absence of an abnormal hirsutism score). For most women with patient-important hirsutism despite cosmetic measures (shaving, plucking, waxing), we suggest starting with pharmacological therapy and adding direct hair removal methods (electrolysis, photoepilation) for those who desire additional cosmetic benefit. For women with mild hirsutism and no evidence of an endocrine disorder, we suggest either pharmacological therapy or direct hair removal methods. For pharmacological therapy, we suggest oral combined estrogen-progestin contraceptives for the majority of women, adding an antiandrogen after 6 months if the response is suboptimal. We recommend against antiandrogen monotherapy unless adequate contraception is used. We suggest against using insulin-lowering drugs. For most women who choose hair removal therapy, we suggest laser/photoepilation.

Consensus Statement on the Use of Oral Contraceptive Pills in Polycystic Ovarian Syndrome Women in India

OBJECTIVE

To provide consensus recommendations for health-care providers on the use of oral contraceptive pills (OCPs) in polycystic ovarian syndrome (PCOS) women in India.

PARTICIPANTS

Extensive deliberations, discussions, and brainstorming were done with different fraternities (specialists) being involved. These included endocrinologists, gynecologists, reproductive endocrinologists, dermatologists, public health experts, researchers, and a project manager with a team to develop the guideline.

EVIDENCE

Published literature was retrieved through searches of Medline and The Cochrane Database from January 2003 to December 2017 using appropriate-controlled vocabulary (e.g., oral contraceptive pills, polycystic ovarian syndrome, long term outcomes, infertility). Clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies' publications and data were also reviewed to suggest the recommendations.

PROCESS

The working group for guideline committee included members from the PCOS Society (India), Indian Society for Assisted Reproduction, The Mumbai Obstetric and Gynecological Society, The Endocrine Society of India, Indian Association of Dermatologists, Venereologists and Leprologists, Cosmetic Dermatology Society (India), Academicians from Medical Colleges, National Institute for Research in Reproductive Health, and a Research Associate. The core team included five reproductive endocrinologists, five gynecologists, five dermatologists, three endocrinologists, two public health experts and one research associate.

CONCLUSIONS

This consensus statement provides the guidance/recommendations for Indian practitioners regarding the use of OCP in women with PCOS. PCOS is one of the common endocrinopathies encountered in gynecological/endocrine practice. The spectrum of this disorder may range from prepubertal girls with premature pubarche, young girls with hirsutism, acne and anovulatory cycles, married women with infertility, and elderly women. Although obesity is a common feature for most PCOS patients, 'lean PCOS' also exists. For several years, OCPs have played an important role in the symptom management of PCOS women. This is due to the fact that OCPs decrease the luteinizing hormone, reduce androgen production, and increase sex hormone-binding globulin, which binds androgens. Several new formulations of OCPs have been developed to decrease the side effects. This includes use of less androgenic progestins and lower doses of ethinyl estradiol. These consensus recommendations help the health provider to choose the right type of OCPs, which will alleviate the symptoms with least side effects. It also gives insight into the indications, contraindications, and concerns regarding its short, intermediate and long-term use.

Oral Spironolactone for Acne Vulgaris in Adult Females: A Hybrid Systematic Review

BACKGROUND

The management of acne in adult females is problematic, with many having a history of treatment failure and some having a predisposition to androgen excess. Alternatives to oral antibiotics and combined oral contraceptives (COCs) are required.

OBJECTIVE

Our aim was to conduct a hybrid systematic review of the evidence for benefits and potential harms of oral spironolactone in the management of acne in adult females.

METHODS

The review was conducted according to a previously published protocol. Three reviewers independently selected relevant studies from the search results, extracted data, assessed the risk of bias, and rated the quality of the evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.

RESULTS

Ten randomized controlled trials (RCTs) and 21 case series were retrieved. All trials were assessed as being at a 'high risk' of bias, and the quality of evidence was rated as low or very low for all outcomes. Apart from one crossover trial that demonstrated statistical superiority of a 200 mg daily dose versus inflamed lesions compared with placebo, data from the remaining trials were unhelpful in establishing the degree of efficacy of lower doses versus active comparators or placebo. Menstrual side effects were significantly more common with the 200 mg dose; frequency could be significantly reduced by concomitant use of a COC. Pooling of results for serum potassium supported the recent recommendation that routine monitoring is not required in this patient population.

CONCLUSION

This systematic review of RCTs and case series identified evidence of limited quality to underpin the expert endorsement of spironolactone at the doses typically used (≤100 mg/day) in everyday clinical practice.

Long-term satisfaction and tolerability with low-dose flutamide: a 20-year surveillance study on 120 hyperandrogenic women

OBJECTIVE

To evaluate the long-term safety, satisfaction and tolerability of flutamide therapy for female hyperandrogenism.

DESIGN

A 20-year surveillance study.

METHODS

Setting: Gynecology Department in a teaching hospital.

PATIENTS

Hyperandrogenic women complaining for hirsutism treatment were followed between February 1995 and April 2015.

INTERVENTIONS

Women received flutamide 125 or 250 mg/day alone (n = 55) or combined with oral contraceptives (n = 65).

MAIN OUTCOME MEASURES

Adverse events, safety, tolerability satisfaction and efficacy were assessed every 6 months during all the follow-up. Lab tests including liver and lipid profiles were also recorded in each control.

RESULTS

Patients under flutamide therapy showed significant improvements in hirsutism scores after 6 months of treatment with a maximum effect at 12 months that was maintained during all the therapy time. Satisfaction reported by patients with the efficacy of the drug in a visual scale was also high. A total of 54.2 % women presented one or more adverse effects during the follow-up; 33.3% showed at least one adverse effect possibly related with the study drug; and 24.1% withdrew from the study because of adverse effects. During the follow-up, as many as 89.9 % of patients abandoned flutamide. Reasons include: questions linked to medical problems (50%), attempt pregnancy (4%) and significant improvement in the symptomatology (35.8%).

CONCLUSIONS

Flutamide is very effective for hirsutism treatment; however, adverse effects are very frequent and affect compliance.

Interventions for hirsutism excluding laser and photoepilation therapy alone: abridged Cochrane systematic review including GRADE assessments

Hirsutism is a common disorder with a major impact on quality of life. The most frequent cause is polycystic ovary syndrome. Effects of interventions (except laser and light-based therapies) were evaluated, including Grading of Recommendations Assessment, Development and Evaluation assessments. Searches included Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library, Medline, Embase and five trials registers to June 2014. We included 157 randomized controlled trials (RCTs) with 10 550 participants. The majority were assessed as having a 'high risk' of bias (123 of 157). The quality of evidence was rated moderate to very low for most outcomes. Pooled data for an oral contraceptive (OCP) (ethinyl oestradiol and cyproterone acetate) compared with another OCP (ethinyl oestradiol and desogestrel) demonstrated that both treatments were effective in reducing Ferriman-Gallwey scores, but the mean difference (MD) was not statistically significant [-1·84, 95% confidence interval (CI): -3·86-0·18]. Flutamide was more effective than placebo in two studies (MD -7·60, 95% CI: -10·53 to -4·67 and MD -7·20, 95% CI: -10·15 to -4·25), as was spironolactone (MD -7·69, 95% CI: -10·12 to -5·26). Spironolactone appeared to be as effective as flutamide (two studies) and finasteride (two studies). However, finasteride and the gonadotropin-releasing analogues showed discrepant results in several RCTs. Metformin was ineffective. Cyproterone acetate combined with OCPs demonstrated greater reductions in Ferriman-Gallwey scores. Lifestyle interventions reduced body mass index but did not show improvement in hirsutism, and although cosmetic measures are frequently used, no RCTs investigating cosmetic treatments were identified. RCTs investigating OCPs in combination with antiandrogens or finasteride vs. OCP alone, or the different antiandrogens and 5α-reductase inhibitors are warranted.

Is hormonal treatment still an option in acne today?

Hormonal treatment is indicated in cases of papulopustular, nodular and conglobate acne in females with identified hyperandrogenism, in adult women who have monthly flare-ups and when standard therapeutic options are unsuccessful or inappropriate. This review summarizes the latest information on hormonal therapies including: combined oral contraceptives; anti-androgens, such as cyproterone acetate, spironolactone and flutamide; low-dose glucocorticoids and gonadotropin-releasing hormone agonists. It also shares the authors' recommendations for treatment based on the studies discussed here, and personal experience.

Guidelines of care for the management of acne vulgaris

Acne is one of the most common disorders treated by dermatologists and other health care providers. While it most often affects adolescents, it is not uncommon in adults and can also be seen in children. This evidence-based guideline addresses important clinical questions that arise in its management. Issues from grading of acne to the topical and systemic management of the disease are reviewed. Suggestions on use are provided based on available evidence.

Management of polycystic ovarian syndrome with Diane-35 or Diane-35 plus metformin

In this study, we assessed the efficacy and safe usage of the oral contraceptive, Diane-35, in the treatment of polycystic ovary syndrome (PCOS) when combined with the drug metformin. Eighty-two patients with PCOS were randomly divided into two equal groups: Diane-35 treatment group and Diane-35 plus metformin group. Three treatment cycles were administered. Patients' biomedical data such as height, weight, waist circumference, hip circumference, body fat percentage, acne score, hirsutism score and serum hormone levels were selected, which were tested between the second and the fifth day of the menstrual cycle and follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone (T), blood glucose, blood lipids and insulin levels(IR) were analyzed. Significant reduction in body mass index (BMI), acne score, LH and T levels were observed in both groups after three months of treatment; on the other hand, high-density lipoprotein cholesterol (HDL) concentration elevated (p < 0.05). Combined treatment group had a significant change in BMI index and fasting blood glucose levels compared to Diane-35 alone treatment group (p < 0.05). With personalized nutrition and exercise program, Diane-35 only group or Diane-35 plus metformin group had both significantly lowered their serum testosterone levels and had improved acne symptoms. Diane-35 plus metformin combination had shown reduced fat percentage levels in patients with PCOS, and had shown improved glucose and lipid metabolism.

Polycystic ovary syndrome: chemical pharmacotherapy

INTRODUCTION

Polycystic ovary syndrome (PCOS) is the most common reproductive endocrine disease among women of childbearing age. The clinical features are heterogeneous and vary in intensity. Hirsutism, menstrual disorders and infertility are the most frequent conditions observed; however, long-term complications (dyslipidemia, hypertension, cardiovascular disease, type 2 diabetes mellitus, endometrial cancer) are also often described. Each disorder may be managed by tailored strategies, employing sequential or combined pharmacological and/or non-pharmacological treatment.

AREAS COVERED

The authors review the drugs used for PCOS management and discuss new approaches. A systematic MEDLINE search regarding the randomized controlled trials, retrospective and observational studies about medical treatments of PCOS, the Cochrane library for reviews and also search for registered trials on ClinicalTrials.gov is performed.

EXPERT OPINION

A uniform treatment for PCOS patients does not exist. Clinicians should perform an accurate evaluation of patients' characteristics, identifying the phenotypic target and, subsequently, the best-tailored treatment to manage one or more clinical issues. Lifestyle intervention should always be the first recommended approach unless other issues indicate that drug or hormonal interventions are superior.

Metabolic profile of Diane-35 versus Diane-35 plus metformin in Chinese PCOS women under standardized life-style changes

OBJECTIVE

The aim of this study was to compare the effect of Diane-35 versus Diane-35 + metformin on metabolic parameters in Chinese PCOS patients.

METHODS

Patients getting individualized life-style modification were treated with Diane-35. Metformin was added according to its indication. Within a 3-month prospective study, metabolic parameters were assessed.

RESULTS

Eighty-three patients were recruited, 45 using Diane-35 and 38 Diane-35 plus metformin. Using Diane-35, triglycerides (TG) (p < 0.05) and tendencially (p < 0.1) total cholesterol (TC) increased, but significant positive effects on BMI, high-density lipoprotein cholesterol (HDL-C), and HDL-C/TC ratio were observed. Other lipids and the parameters for glucose metabolism remained unchanged. In the combination group, no negative effect on TG and TC was seen, other lipid fractions improved, as well as BMI, % body fat, and all parameters for glucose metabolism like fasting plasma glucose (FPG), fasting insulin, HOMA-insulin-resistance index, and insulin sensitivity index (ISI), whereby the beneficial effect of metformin got significance compared with Diane-35 for BMI, FPG, and ISI.

CONCLUSION

With the exception of increasing triglycerides, Diane-35 had no relevant negative effects in the metabolic system. It does not negatively impact the beneficial effects of metformin in lipids and glucose metabolism. Diane-35 plus metformin is effective in improving the metabolic profile of Chinese PCOS patients.

Evidence-based approach to cutaneous hyperandrogenism in women

Hirsutism, acne, and androgenetic alopecia are classically considered signs of cutaneous hyperandrogenism (CHA). These common skin findings have significant impacts on the quality of patients' lives and pose the diagnostic challenge of excluding underlying disorders. Many with CHA have normal serum androgen levels. Hirsutism is more strongly associated with hyperandrogenism than are acne or androgenetic alopecia. Variable association of CHA with hyperandrogenemia results from the complexity of the underlying pathophysiology, including factors local to the pilosebaceous unit. CHA often occurs in the setting of polycystic ovary syndrome, the most common disorder of hyperandrogenism, but can also present in uncommon conditions, including nonclassic adrenal hyperplasia and androgen-producing tumors. A thorough history and full skin examination are important to guide appropriate diagnostic evaluation. Oral contraceptive pills with or without antiandrogens can provide therapeutic benefit for hirsutism and acne. Medical options for androgenetic alopecia remain limited. Multidisciplinary approaches may be needed given endocrine, metabolic, reproductive, and psychiatric disorders associated with CHA. More high-quality studies into the mechanisms of CHA and the benefits of antiandrogenic therapies are needed. We provide an evidence-based review of key diagnostic and therapeutic considerations in the treatment of women with CHA.

Interventions for hirsutism (excluding laser and photoepilation therapy alone)

BACKGROUND

Hirsutism occurs in 5% to 10% of women of reproductive age when there is excessive terminal hair growth in androgen-sensitive areas (male pattern). It is a distressing disorder with a major impact on quality of life. The most common cause is polycystic ovary syndrome. There are many treatment options, but it is not clear which are most effective.

OBJECTIVES

To assess the effects of interventions (except laser and light-based therapies alone) for hirsutism.

SEARCH METHODS

We searched the Cochrane Skin Group Specialised Register, CENTRAL (2014, Issue 6), MEDLINE (from 1946), EMBASE (from 1974), and five trials registers, and checked reference lists of included studies for additional trials. The last search was in June 2014.

SELECTION CRITERIA

Randomised controlled trials (RCTs) in hirsute women with polycystic ovary syndrome, idiopathic hirsutism, or idiopathic hyperandrogenism.

DATA COLLECTION AND ANALYSIS

Two independent authors carried out study selection, data extraction, 'Risk of bias' assessment, and analyses.

MAIN RESULTS

We included 157 studies (sample size 30 to 80) comprising 10,550 women (mean age 25 years). The majority of studies (123/157) were 'high', 30 'unclear', and four 'low' risk of bias. Lack of blinding was the most frequent source of bias. Treatment duration was six to 12 months. Forty-eight studies provided no usable or retrievable data, i.e. lack of separate data for hirsute women, conference proceedings, and losses to follow-up above 40%.Primary outcomes, 'participant-reported improvement of hirsutism' and 'change in health-related quality of life', were addressed in few studies, and adverse events in only half. In most comparisons there was insufficient evidence to determine if the number of reported adverse events differed. These included known adverse events: gastrointestinal discomfort, breast tenderness, reduced libido, dry skin (flutamide and finasteride); irregular bleeding (spironolactone); nausea, diarrhoea, bloating (metformin); hot flushes, decreased libido, vaginal dryness, headaches (gonadotropin-releasing hormone (GnRH) analogues)).Clinician's evaluation of hirsutism and change in androgen levels were addressed in most comparisons, change in body mass index (BMI) and improvement of other clinical signs of hyperandrogenism in one-third of studies.The quality of evidence was moderate to very low for most outcomes.There was low quality evidence for the effect of two oral contraceptive pills (OCPs) (ethinyl estradiol + cyproterone acetate versus ethinyl estradiol + desogestrel) on change from baseline of Ferriman-Gallwey scores. The mean difference (MD) was -1.84 (95% confidence interval (CI) -3.86 to 0.18).There was very low quality evidence that flutamide 250 mg, twice daily, reduced Ferriman-Gallwey scores more effectively than placebo (MD -7.60, 95% CI -10.53 to -4.67 and MD -7.20, 95% CI -10.15 to -4.25). Participants' evaluations in one study with 20 participants confirmed these results (risk ratio (RR) 17.00, 95% CI 1.11 to 259.87).Spironolactone 100 mg daily was more effective than placebo in reducing Ferriman-Gallwey scores (MD -7.69, 95% CI -10.12 to -5.26) (low quality evidence). It showed similar effectiveness to flutamide in two studies (MD -1.90, 95% CI -5.01 to 1.21 and MD 0.49, 95% CI -1.99 to 2.97) (very low quality evidence), as well as to finasteride in two studies (MD 1.49, 95% CI -0.58 to 3.56 and MD 0.40, 95% CI -1.18 to 1.98) (low quality evidence).Although there was very low quality evidence of a difference in reduction of Ferriman-Gallwey scores for finasteride 5 mg to 7.5 mg daily versus placebo (MD -5.73, 95% CI -6.87 to -4.58), it was unlikely it was clinically meaningful. These results were reinforced by participants' assessments (RR 2.06, 95% CI 0.99 to 4.29 and RR 11.00, 95% CI 0.69 to 175.86). However, finasteride showed inconsistent results in comparisons with other treatments, and no firm conclusions could be reached.Metformin demonstrated no benefit over placebo in reduction of Ferriman-Gallwey scores (MD 0.05, 95% CI -1.02 to 1.12), but the quality of evidence was low. Results regarding the effectiveness of GnRH analogues were inconsistent, varying from minimal to important improvements.We were unable to pool data for OCPs with cyproterone acetate 20 mg to 100 mg due to clinical and methodological heterogeneity between studies. However, addition of cyproterone acetate to OCPs provided greater reductions in Ferriman-Gallwey scores.Two studies, comparing finasteride 5 mg and spironolactone 100 mg, did not show differences in participant assessments and reduction of Ferriman-Gallwey scores (low quality evidence). Ferriman-Gallwey scores from three studies comparing flutamide versus metformin could not be pooled (I² = 62%). One study comparing flutamide 250 mg twice daily with metformin 850 mg twice daily for 12 months, which reached a higher cumulative dosage than two other studies evaluating this comparison, showed flutamide to be more effective (MD -6.30, 95% CI -9.83 to -2.77) (very low quality evidence). Data showing reductions in Ferriman-Gallwey scores could not be pooled for four studies comparing finasteride with flutamide as the results were inconsistent (I² = 67%).Studies examining effects of hypocaloric diets reported reductions in BMI, but which did not result in reductions in Ferriman-Gallwey scores. Although certain cosmetic measures are commonly used, we did not identify any relevant RCTs.

AUTHORS' CONCLUSIONS

Treatments may need to incorporate pharmacological therapies, cosmetic procedures, and psychological support. For mild hirsutism there is evidence of limited quality that OCPs are effective. Flutamide 250 mg twice daily and spironolactone 100 mg daily appeared to be effective and safe, albeit the evidence was low to very low quality. Finasteride 5 mg daily showed inconsistent results in different comparisons, therefore no firm conclusions can be made. As the side effects of antiandrogens and finasteride are well known, these should be accounted for in any clinical decision-making. There was low quality evidence that metformin was ineffective for hirsutism and although GnRH analogues showed inconsistent results in reducing hirsutism they do have significant side effects.Further research should consist of well-designed, rigorously reported, head-to-head trials examining OCPs combined with antiandrogens or 5α-reductase inhibitor against OCP monotherapy, as well as the different antiandrogens and 5α-reductase inhibitors against each other. Outcomes should be based on standardised scales of participants' assessment of treatment efficacy, with a greater emphasis on change in quality of life as a result of treatment.

The effect of chromium supplementation on polycystic ovary syndrome in adolescents

BACKGROUND

Polycystic ovary syndrome (PCOS) is a common condition. Treatment with chromium has been shown to improve insulin sensitivity in adults with PCOS. Treatment of adolescents with PCOS remains a challenge.

OBJECTIVE

To investigate the effect of chromium supplementation on the various components of polycystic ovary syndrome in adolescent girls.

PATIENTS AND METHODS

Thirty-five adolescent girls with PCOS were enrolled. History of menstrual irregularities was recorded. All underwent physical examination for presence of acne, scoring of hirsutism, and calculation of body mass index. Pelvic ultrasonography was done and serum free testosterone was measured in all subjects. All subjects received 1000 μg chromium picolinate for 6 months followed by re-evaluation.

RESULTS

Mean (SD) age was 15.5 (1) years (range: 14-17 y). No significant change in BMI standard deviation score (SDS) with chromium supplementation was noted (1.9 (0.7) SDS vs 2 (0.7) SDS, P = .638). The number of patients with oligo/amenorrhea decreased with treatment (29/35 (83%) versus 11/35 (31%), P < .001). Significant reduction in mean ovarian volume (P < .001), total follicular count (P < .034), and free testosterone (P< .002) was observed. No significant improvement in acne or hirsutim was noted.

CONCLUSION

Supplementation with chromium to adolescents with PCOS is a promising treatment option.

Hirsutism: an evidence-based treatment update

BACKGROUND

Hirsutism has a relatively high prevalence among women. Depending upon societal and ethnic norms, it can cause significant psychosocial distress. Importantly, hirsutism may be associated with underlying disorders and co-morbidities. Hirsutism should not simply be looked upon as an issue of cosmesis. Patients require appropriate evaluation so that underlying etiologies and associated sequelae are recognized and managed. Treatment of hirsutism often requires a multidisciplinary approach, and a variety of physical or pharmacologic modalities can be employed. Efficacy of these therapies is varied and depends, among other things, upon patient factors including the underlying etiology, hormonal drive, and local tissue sensitivity to androgens.

OBJECTIVE

The objective of this paper is to review and summarize current evidence evaluating the efficacy of various treatment modalities for hirsutism in premenopausal women.

METHODS

Online databases were searched to identify all relevant prior systematic reviews and meta-analyses as well as recently published (2012-present) randomized controlled trials (RCTs) on hirsutism treatment.

RESULTS

Four recently published RCTs met criteria for inclusion in our review. In addition, one meta-analysis and one systematic review/treatment guideline were identified in the recent literature. Physical modalities and oral contraceptive pills (OCPs) remain first-line treatments. Evidence supports the use of electrolysis for permanent hair removal in localized areas and lasers (particularly alexandrite and diode lasers) for permanent hair reduction. Topical eflornithine can be used as monotherapy for mild hirsutism and as an adjunct therapy with lasers or pharmacotherapy in more severe cases. Combined OCPs as a class are superior to placebo; however, antiandrogenic and low-dose neutral OCPs may be slightly more efficacious in improving hirsutism compared with other types of OCPs. Antiandrogens are indicated for moderate to severe hirsutism, with spironolactone being the first-line antiandrogen and finasteride and cyproterone acetate being second-line antiandrogens. Due to its risk for hepatotoxicity, flutamide is not considered a first-line therapy. If used, the lowest effective dose should be administered with careful monitoring of liver enzymes. Monotherapy with an insulin sensitizer does not significantly improve hirsutism. While insulin sensitizers improve important metabolic and endocrine aberrations in polycystic ovary syndrome, they are not recommended when hirsutism is the sole indication for use. Lifestyle modification counseling is recommended. Gonadotropin-releasing hormone analogs and glucocorticoids are only recommended in specific circumstances. Additional therapies without sufficient supportive evidence of efficacy are ovarian surgery, statins (HMG-CoA reductase inhibitors), and vitamin D supplementation.

LIMITATIONS

In general, most therapies garner recommendations that are weak (where the estimates of benefits versus risks of therapy are either closely balanced or uncertain) and are based on low- to moderate-quality evidence.

CONCLUSIONS

Risks and benefits of treatment must be carefully considered and discussed with the patient. Expectations for efficacy should be appropriately set. A minimum of 6 months is required to see benefit from pharmacotherapy and lifelong treatment is often necessary for sustained benefit.

Ovulatory effects of flutamide in the polycystic ovary syndrome

The long-term effects and tolerability of flutamide (Flu) on the menstrual cycle and the ovulatory function of hyperandrogenic women with or without polycystic ovary syndrome (PCOS) were investigated. The study included 118 white women with the diagnosis of various forms of hyperandrogenism (80 PCOS and 38 non-PCOS patients). Patients received Flu for three years at dosages that declined each of the three years (250, 125 and 62.5 mg/day). Sex steroid, ovulatory function and menstrual profile at baseline and during each year of Flu treatment were evaluated. Flu therapy showed a significant increase in the percentage of cycles that were ovulatory (with progesterone concentrations greater than 4 ng/ml in mid-luteal phase) and concomitant regularization of the menstrual profile in PCOS patients. A luteinizing hormone decrease and an estrone, estradiol and 17-hydroxyprogesterone increase are also observed during treatment. Regular cycles persisted in non-PCOS patients. The results were maintained during the three years of treatment. The study suggests that Flu is a satisfactory therapeutic regimen of the chronic anovulation and the irregularities of the menstrual cycle in hyperandrogenic PCOS patients in the long run.

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

BACKGROUND

Hirsutism, defined by the presence of excessive terminal hair in androgen-sensitive areas of the female body, is one of the most common disorders in women during reproductive age.

METHODS

We conducted a systematic review and critical assessment of the available evidence pertaining to the epidemiology, pathophysiology, diagnosis and management of hirsutism.

RESULTS

The prevalence of hirsutism is ~10% in most populations, with the important exception of Far-East Asian women who present hirsutism less frequently. Although usually caused by relatively benign functional conditions, with the polycystic ovary syndrome leading the list of the most frequent etiologies, hirsutism may be the presenting symptom of a life-threatening tumor requiring immediate intervention.

CONCLUSIONS

Following evidence-based diagnostic and treatment strategies that address not only the amelioration of hirsutism but also the treatment of the underlying etiology is essential for the proper management of affected women, especially considering that hirsutism is, in most cases, a chronic disorder needing long-term follow-up. Accordingly, we provide evidence-based guidelines for the etiological diagnosis and for the management of this frequent medical complaint.

Retrospective, observational study on the effects and tolerability of flutamide in a large population of patients with acne and seborrhea over a 15-year period

The long-term effects and tolerability of flutamide (Flu) in women with acne and seborrhea were evaluated. Over the 15-year period, which spans from January 1991 to January 2006, a total of 230 Caucasian women with acne, 211 of which also with seborrhea, received yearly reducing doses (250, 125, and 62.5 mg/day) of Flu alone or combined with oral contraceptive for a period varying from 3 to 6 years and more. Clinical and endocrine evaluations were performed half-yearly and yearly, respectively, in the first 3 years of the study, and yearly in the following years. Liver function evaluations were performed quarterly. Both the groups of patients under Flu therapy showed a similar, marked decrease in acne and seborrhea scores after 6 months of treatment compared with basal values. The maximum drug effect was observed after 1 year, and it was maintained during the following years of treatment. Androgens were strongly suppressed during treatment. During the first year of treatment with 250 mg/day, 4.8% of patients interrupted the study due to hepatic disorders. During the following years on the 125 and 62.5 mg/day doses, no transaminase elevation was observed. The study supports very low-dose Flu as a first-line therapy for women with acne and seborrhea.

Flutamide versus a cyproterone acetate-ethinyl estradiol combination in moderate acne: a pilot randomized clinical trial

BACKGROUND

The use of oral flutamide is rarely investigated in acne therapy. The aim of this study was to compare the efficacy of oral flutamide with that of a cyproterone-estradiol combination in treating acne lesions.

METHODS

A randomized clinical trial enrolled patients with moderate acne into two equal groups to receive either oral flutamide or the cyproterone-estradiol combination for 6 months. Lesion count, Acne Severity Index, and Global Acne Grading system (GAGS) scores were used to assess improvement in acne lesions. The dichotomous measurement scale for primary endpoint assessment was defined as improvement from moderate to mild acne based on GAGS score. Patient satisfaction and dermal fat were also assessed. Intention to treat and per protocol analyses were done, reporting related effect sizes.

RESULTS

Both treatments resulted in substantial improvement in acne lesions. Although flutamide seemed to have higher efficacy, an intention to treat analysis did not find the two treatment protocols to be different. The relative risk in intention to treat analysis was 1.8 (95% confidence interval [CI] 0.89-1.6), and was 1.33 (95% CI 1.03-1.72) for the per protocol analysis. The number needed to treat for flutamide compared with the cyproterone-estradiol combination was 7.7 and 4.2 in the intention to treat and per protocol analyses, respectively.

CONCLUSION

Flutamide appears to be more effective than a cyproterone-estradiol combination in some aspects of acne treatment, but this requires confirmation in a larger trial.

Prospective Cohort Study on the Effects and Tolerability of Flutamide in Patients with Female Pattern Hair Loss

Background

Flutamide has been rarely used (or the treatment of female pattern hair loss (FPHL). Flutamide treatment for FPHL has not been evaluated in long-term studies with sufficiently large numbers of women.

Objective:

To evaluate long-term effects, safety, and tolerability of flutamide in women with FPHL.

Methods:

A prospective cohort study was conducted in our tertiary care university hospital. The cohort included 101 women diagnosed with FPHL from January 1991 to January 2006. These women received yearly reducing doses (250, 125, and 62.5 mg/day) of flutamide for 4 years. The cohort included 33 patients treated with flutamide alone and 68 treated with flutamide combined with an oral contraceptive. Clinical and endocrine evaluations were assessed semiannually and annually, respectively, in the first 3 years of the study, and once in the following year. Liver function was evaluated quarterly.

Results:

Both groups showed a marked decrease in alopecia scores after 12 months of flutamide therapy, compared with baseline values. The maximum drug effect occurred after 2 years and was maintained during the following 2 years of treatment. Androgens were strongly suppressed. During the first year of treatment, 4% of patients abandoned the study due to hepatic disorders related to the drug. During the following years, with the lower treatment regimen, no patient abandoned the study because of hepatic alterations.

Conclusions:

Flutamide is a satisfactory therapeutic regimen for treatment of FPHL in the long run. Moreover, the use of very low doses (62.5 mg/day) of flutamide is associated with complete hepatic tolerability and high adherence.

Treatment options for polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women. The clinical manifestation of PCOS varies from a mild menstrual disorder to severe disturbance of reproductive and metabolic functions. Management of women with PCOS depends on the symptoms. These could be ovulatory dysfunction-related infertility, menstrual disorders, or androgen-related symptoms. Weight loss improves the endocrine profile and increases the likelihood of ovulation and pregnancy. Normalization of menstrual cycles and ovulation could occur with modest weight loss as little as 5% of the initial weight. The treatment of obesity includes modifications in lifestyle (diet and exercise) and medical and surgical treatment. In PCOS, anovulation relates to low follicle-stimulating hormone concentrations and the arrest of antral follicle growth in the final stages of maturation. This can be treated with medications such as clomiphene citrate, tamoxifen, aromatase inhibitors, metformin, glucocorticoids, or gonadotropins or surgically by laparoscopic ovarian drilling. In vitro fertilization will remain the last option to achieve pregnancy when others fail. Chronic anovulation over a long period of time is also associated with an increased risk of endometrial hyperplasia and carcinoma, which should be seriously investigated and treated. There are androgenic symptoms that will vary from patient to patient, such as hirsutism, acne, and/or alopecia. These are troublesome presentations to the patients and require adequate treatment. Alternative medicine has been emerging as one of the commonly practiced medicines for different health problems, including PCOS. This review underlines the contribution to the treatment of different symptoms.

Cyproterone acetate or drospirenone containing combined oral contraceptives plus spironolactone or cyproterone acetate for hirsutism: randomized comparison of three regimens

OBJECTIVE

To compare the effectiveness of three different combinations of combined oral contraceptives (COCs) and anti-androgens in the treatment of hirsutism.

METHODS

A total of 134 women with moderate and severe hirsutism were randomly assigned to three treatment regimens: Group I received 30 μg of ethinyl estradiol (EE)/3 mg of drospirenone (DRSP) plus 100 mg of cyproterone acetate (CPA) (n = 45); group II received 30 μg of EE/3 mg of DRSP plus 100 mg of spironolactone (n = 44); and group III received 35 μg of EE/2 mg of CPA plus 100 mg of CPA (n = 45), daily for 6 months. The decrease in the modified Ferriman-Gallwey hirsutism score (mFGS) was the main outcome measure.

RESULTS

The mean decrease in mFGS after 3 and 6 months of the treatment course was 26% and 49% in group I (both p < 0.01), 27% and 49% in group II (both p < 0.01), and 25% and 45% in group III (both p < 0.01), respectively, when compared with baseline. Although the mFGS was significantly decreased in all groups, there was no significant difference between groups.

CONCLUSION

CPA or DRSP containing COCs in combination with CPA or spironolactone have similar effects for the treatment of hirsutism.

Comparison of effects of 3 mg drospirenone plus 20 μg ethinyl estradiol alone or combined with metformin or cyproterone acetate on classic metabolic cardiovascular risk factors in nonobese women with polycystic ovary syndrome

OBJECTIVE

To evaluate the effects of a pill with drospirenone (3 mg) plus ethinyl E(2) (20 μg) (DRP/20EE) alone or associated with metformin or cyproterone acetate (CPA) on some metabolic cardiovascular risk factors in women with polycystic ovary syndrome (PCOS).

DESIGN

Randomized, open-label clinical trial.

SETTING

Academic medical clinic.

PATIENT(S)

Forty-eight hirsute women with PCOS.

INTERVENTION(S)

Patients were randomized to treatment with DRP/20EE or with DRP/20EE plus metformin (1,500 mg/d) or with DRP/20EE plus CPA (12.5 mg/d, 10 days per cycle) for 6 months.

MAIN OUTCOME MEASURE(S)

Blood pressure, lipid profile, and indexes of glucose tolerance and insulin sensitivity were assessed before and after 6 months of treatment.

RESULT(S)

Body mass index and blood pressure were not modified by any treatment. Treatment with DRP/EE20 did not change the lipid profile; DRP/EE20 plus metformin significantly increased high-density lipoprotein cholesterol concentrations; DRP/EE20 plus CPA significantly increased triglycerides and total cholesterol. The area under the curve for insulin was significantly decreased by DRP/EE20 and DRP/EE20 plus metformin, but it was significantly increased by DRP/EE20 plus CPA. Treatment with DRP/EE20 plus CPA significantly increased the homeostasis model assessment of insulin resistance index and significantly reduced the glucose to insulin ratio index. Treatment with DRP/EE20 significantly increased the glucose to insulin ratio index.

CONCLUSION(S)

Treatment with DRP/EE20 improved insulin sensitivity in hirsute women with PCOS, with no deterioration of lipid profile. This effect was not ameliorated by the addition of metformin. The positive metabolic effects of DRP are abolished by the concomitant use of CPA.

Retrospective observational study on the effects and tolerability of flutamide in a large population of patients with various kinds of hirsutism over a 15-year period

OBJECTIVE

The aim of the study was to evaluate the long-term effects and tolerability of flutamide (Flu) in hirsute women. To the best of our knowledge, this study represents the largest report, concerning the population studied and the duration of treatment, to evaluate Flu use in hirsutism treatment.

DESIGN, PATIENTS AND METHODS

Over a 15-year period spanning from January 1991 to January 2006, a total of 414 premenopausal women with hirsutism of different aetiopathogeneses received yearly reducing doses (250, 125 and 62.5 mg/day) of Flu alone or in combination with oral contraceptives for a period varying from at least 3 to 8 years and more. Clinical and endocrine evaluations were assessed half-yearly and yearly respectively in the first 3 years of the study, and yearly in the following years. Liver function evaluations were assessed quarterly.

RESULTS

Both the groups of patients under Flu therapy showed a marked decrease in hirsutism scores after 12 months compared with basal values. The maximum drug effect was observed after 2 years, and it was maintained during the following years of treatment. Androgens were strongly suppressed during treatment. During the first year of treatment, 6.0% of patients abandoned the study due to hepatic disorders related to the drug. During the following years with the lowest treatment regimen, none of the patients abandoned the study due to hepatic discomfort.

CONCLUSIONS

Flu is a satisfactory therapeutic regimen for any form of hirsutism in the long run. Moreover, the use of very low doses of Flu is associated with minimal side-effects and high compliance.

Comprehensive clinical management of hirsutism

Hirsutism is an excessive body and facial hair growth in women in locations where is normally minimal or absent following a hair-male pattern. For this reason is not uncommon that hirsutism raises psychological, cosmetic and social concerns. There are many treatment modalities that can be summarised into two broad groups: pharmacologic and non-pharmacologic treatment. Until now, medical treatment has been designed to interfere with the synthesis of androgen at the ovarian or adrenal level, or inhibit the effect of androgen at the receptor level, although recent progresses test other options such as insulin modulators or ornithine decarboxylase inhibitors. Mechanical treatment includes laser hair removal, electrolysis, depilatory creams, plucking and waxing. This article presents a general overview of hirsutism treatment options.

Management of acne vulgaris: an evidence-based update

This review summarizes clinically important findings from 3 systematic reviews, 1 updated guideline and a selection from the 62 randomized controlled trials (RCTs) published between February 2007 and January 2009 on the topic of acne vulgaris. Low glycaemic-load diets might reduce acne severity but this remains unproven. Written patient information leaflets have not been surpassed by other communication methods. New combination topical treatments have not shown convincing advantages over current combination products such as clindamycin/benzoyl peroxide. Topical dapsone is superior to placebo but has yet to be compared with standard topical treatments. Long-term topical tretinoin to prevent nonmelanoma skin cancer in elderly men was associated with higher all-cause mortality, but there is currently no evidence of increased mortality for topical retinoid use when treating acne. All oral tetracyclines have similar efficacy, yet minocycline is the most costly. Oral isotretinoin monotherapy remains the gold-standard treatment for severe acne. Flutamide plus the oral contraceptive pill is beneficial for acne associated with polycystic ovary syndrome. Photodynamic therapy, phototherapy and laser therapy cannot be recommended universally for acne until minimal postinflammatory pigmentation and longer-term benefit can be shown, especially with current high costs. Development of non-antibiotic therapies is preferable to minimize the risk of community antibiotic resistance. Future trials should use active comparators at optimum doses and avoid noninferiority comparisons unless appropriately powered. Trials need to shift from using multiple, unvalidated outcome measures to including patient-reported and quality-of-life outcomes, and all trials should be registered on a public clinical-trials database.

Hepatotoxicity during low-dose flutamide treatment for hirsutism

BACKGROUND

The nonsteroidal antiandrogenic drug flutamide is a safe and generally well-tolerated drug used for the treatment of prostate cancer and female hyperandrogenism.

CASE

We describe the case of a 26-year-old girl with amenorrhea and severe hirsutism who was treated with flutamide 250 mg/day and developed liver toxicity during therapy.

RESULTS

Other causes of liver toxicity were appropriately ruled out. The use of the standard Council for International Organization of Medical Sciences (CIOMS) scale and the Maria & Vitorino (M&V) scale indicated a highly probable relationship between the development of liver toxicity and flutamide therapy. Severe liver dysfunction has been rarely documented in women with hirsutism treated with flutamide, even though cases of fulminant liver failure have been described. The mechanisms responsible for the occurrence of hepatotoxicity during treatment with flutamide are unknown, but mitochondrial dysfunction seems to be implicated.

CONCLUSION

The potential of flutamide to act as a potent hepatotoxin should be kept in mind when treatment with this drug is being planned. This case reminds us that patients who are receiving flutamide should be regularly monitored for liver function. If drug-induced liver injury is suspected, flutamide must be discontinued promptly to avoid progression of liver injury.

Treatment for polycystic ovary syndrome: a critical appraisal of treatment options

The management of polycystic ovary syndrome (PCOS) usually spans a woman's reproductive years. While the treatment of symptoms is a primary concern, given its long-term nature, the benefits and potential risks need to be assessed and balanced. The variability of presentation coupled with the phenotypic diversity of this patient population, requires the individualization of treatment to each patient. Periodically, the regimen has to be modified owing to a desire for pregnancy, necessitating ovulation induction in this anovulatory group of women. Finally, for any treatment offered, consideration should be given to potential adverse effects on the fetus should spontaneous ovulation and unplanned pregnancy occur. This review highlights the current issues surrounding PCOS and provides a critical appraisal of treatment options.
