The association between the combined oral contraceptive pill and insulin resistance, dysglycemia and dyslipidemia in women with polycystic ovary syndrome: a systematic review and meta-analysis of observational studies

Hormonal and natural contraceptives: a review on efficacy and risks of different methods for an informed choice

The debate about contraception has become increasingly important as more and more people seek safe and effective contraception. More than 1 billion women of reproductive age worldwide need a method of family planning, and wellbeing, socio-economic status, culture, religion and more influence the reasons why a woman may ask for contraception. Different contraceptive methods exist, ranging from 'natural methods' (fertility awareness-based methods - FABMs) to barrier methods and hormonal contraceptives (HCs). Each method works on a different principle, with different effectiveness.FABMs and HCs are usually pitted against each other, although it's difficult to really compare them. FABMs are a valid alternative for women who cannot or do not want to use hormone therapy, although they may have a high failure rate if not used appropriately and require specific training. HCs are commonly used to address various clinical situations, although concerns about their possible side effects are still widespread. However, many data show that the appropriate use of HC has a low rate of adverse events, mainly related to personal predisposition.The aim of this review is to summarize the information on the efficacy and safety of FABMs and HCs to help clinicians and women choose the best contraceptive method for their needs.

Randomized control trial to compare effects of ultra-low dose (Ethinylestradiol 20 μg or 15 μg) with low dose (Ethinylestradiol 30 μg) hormonal pills on lipid discordance in non-obese PCOS women

OBJECTIVE

Regular users of hormonal contraceptive pills show marked heterogeneity in metabolic effects with variations in compositions. This might be due to choice of outcome variables for comparison. Total cholesterol-high-density lipoprotein ratio (TC/HDL) discordance with low-density lipoprotein (LDL-C) has now become an established marker of future risk for atherosclerotic cardiovascular disease and stable to variations in user.

METHODS

The present study was a randomized controlled trial to compare prevalence of TC/HDL and LDL discordance among non-obese women with polycystic ovarian syndrome (PCOS) treated with hormonal pills. Women were randomized into three arms, two arms received ultra-low dose pills (Ethinylestradiol [EE] 20 μg with drosperinone 3 mg or EE 15 μg with gestodene 60 μg) and one arm received low dose pill (EE 30 μg with desogestrel 150 μg). The role of baseline participant features and pill composition on discordance was determined.

RESULTS

Discordance was observed in more than a quarter of the participants before intervention. After 1 year of treatment, less than a fifth of the participants were discordant. Ultralow-dose pill users had lower discordance, LDL, and TC than low-dose pill users after 1 year of treatment. The random forest, a non-linear classifier, showed the highest accuracy in predicting discordance. The baseline Parameters with the maximal impact on the occurrence of discordance were triglyceride, homeostatic model assessment for insulin resistance, body mass index, and high density lipoprotein.

CONCLUSION

Non-obese PCOS women on ultra-low dose pill have a lower risk of acquiring future atherosclerotic cardiovascular disease.

Association between oral contraceptives with lipid profile: results from Hoveyzeh cohort study (HCS)

BACKGROUND

Oral contraceptives (OCs) affect lipid metabolism, which can cause hyperlipidemia, a risk factor for cardiovascular diseases. The study was designed to evaluate the possible changes in lipid profile due to using OCs.

METHODS

A cross-sectional study was conducted from April 2016 to August 2018 among women from the baseline phase Hoveyzeh cohort study (HCS). Sociodemographic data, anthropometric measurements, physical activity, and biochemical blood tests were measured for every participant. Multiple logistic regression was used to adjust the potential confounders.

RESULTS

Among 2272 participants, 1549 women were OC users, and 723 women were non-user OCs. The mean lipid profile levels were higher in OC users than in non-user OCs. Odds of abnormal Total cholesterol (TC) in OC users were significantly higher than those of non-users OCs [OR = 1.29 (95% CI;1.05 to 1.58)]. Also, the Odds of abnormal low-density lipoprotein (LDL) in OC users was 12% higher than in non-user OCs. However, no significant relationship between abnormal LDL with Oral Contraceptive Pills (OCPs) was observed.

CONCLUSIONS

The mean lipid profile was higher in OC users compared to non-user OCs. This finding highlights the need for public health strategies to prevent and detect hyperlipidemia in user OCs.

Women's health, hormonal balance, and personal autonomy

Hormone-based contraception disrupts hormonal balance, creating artificial states of anovulation and threatening women's health. We reviewed its main adverse effects and mechanisms on accelerated ovarian aging, mental health (emotional disruptions, depression, and suicide), sexuality (reduced libido), cardiovascular (brain stroke, myocardial infarction, hypertension, and thrombosis), and oncological (breast, cervical, and endometrial cancers). Other "collateral damage" includes negative effects on communication, scientific mistrust, poor physician-patient relationships, increased patient burden, economic drain on the healthcare system, and environmental pollution. Hormone-sensitive tumors present a dilemma owing to their potential dual effects: preventing some cancers vs. higher risk for others remains controversial, with denial or dismissal as non-relevant adverse effects, information avoidance, and modification of scientific criteria. This lack of clinical assessment poses challenges to women's health and their right to autonomy. Overcoming these challenges requires an anthropological integration of sexuality, as the focus on genital bodily union alone fails to encompass the intimate relational expression of individuals, complete sexual satisfaction, and the intertwined feelings of trust, safety, tenderness, and endorsement of women's femininity.

Oral and Vaginal Hormonal Contraceptives Induce Similar Unfavorable Metabolic Effects in Women with PCOS: A Randomized Controlled Trial

This clinical trial aims to compare hormonal and metabolic changes after a 9-week continuous use of oral or vaginal combined hormonal contraceptives (CHCs) in women with polycystic ovary syndrome (PCOS). We recruited 24 women with PCOS and randomized them to use either combined oral (COC, n = 13) or vaginal (CVC, n = 11) contraception. At baseline and 9 weeks, blood samples were collected and a 2 h glucose tolerance test (OGTT) was performed to evaluate hormonal and metabolic outcomes. After treatment, serum sex hormone binding globulin (SHBG) levels increased (p < 0.001 for both groups) and the free androgen index (FAI) decreased in both study groups (COC p < 0.001; CVC p = 0.007). OGTT glucose levels at 60 min (p = 0.011) and AUCglucose (p = 0.018) increased in the CVC group. Fasting insulin levels (p = 0.037) increased in the COC group, and insulin levels at 120 min increased in both groups (COC p = 0.004; CVC p = 0.042). There was a significant increase in triglyceride (p < 0.001) and hs-CRP (p = 0.032) levels in the CVC group. Both oral and vaginal CHCs decreased androgenicity and tended to promote insulin resistance in PCOS women. Larger and longer studies are needed to compare the metabolic effects of different administration routes of CHCs on women with PCOS.

Conversion of Classical and 11-Oxygenated Androgens by Insulin-Induced AKR1C3 in a Model of Human PCOS Adipocytes

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy in women. A common symptom of PCOS is hyperandrogenism (AE); however, the source of these androgens is uncertain. Aldo-keto reductase family 1 member C3 (AKR1C3) catalyzes the formation of testosterone (T) and 5α-dihydrotestosterone (DHT) in peripheral tissues, which activate the androgen receptor (AR). AKR1C3 is induced by insulin in adipocytes and may be central in driving the AE in PCOS. We elucidated the conversion of both classical and 11-oxygenated androgens to potent androgens in a model of PCOS adipocytes. Using high-performance liquid chromatography (HPLC) discontinuous kinetic assays to measure product formation by recombinant AKR1C3, we found that the conversion of 11-keto-Δ4-androstene-3,17-dione (11K-4AD) to 11-ketotestosterone (11K-T) and 11-keto-5α-androstane-3,17-dione (11K-5AD) to 11-keto-5α-dihydrotestosterone (11K-DHT) were superior to the formation of T and DHT. We utilized a stable isotope dilution liquid chromatography high resolution mass spectrometric (SID-LC-HRMS) assay for the quantification of both classical and 11-oxygenated androgens in differentiated Simpson-Golabi-Behmel syndrome adipocytes in which AKR1C3 was induced by insulin. Adipocytes were treated with adrenal derived 11β-hydroxy-Δ4-androstene-3,17-dione (11β-OH-4AD), 11K-4AD, or Δ4-androstene-3,17-dione (4AD). The conversion of 11β-OH-4AD and 11K-4AD to 11K-T required AKR1C3. We also found that once 11K-T is formed, it is inactivated to 11β-hydroxy-testosterone (11β-OH-T) by 11β-hydroxysteroid dehydrogenase type 1 (HSD11B1). Our data reveal a unique role for HSD11B1 in protecting the AR from AE. We conclude that the 11-oxygenated androgens formed in adipocytes may contribute to the hyperandrogenic profile of PCOS women and that AKR1C3 is a potential therapeutic target to mitigate the AE of PCOS.

Cardio-Metabolic Disease and Polycystic Ovarian Syndrome (PCOS): A Narrative Review

Polycystic ovarian syndrome (PCOS) is considered the most common endocrine disorder affecting females in today's world. Although it has been primarily studied and discussed in terms of its reproductive symptoms such as infertility, amenorrhea or oligomenorrhea, acne, hirsutism, and mood disorders, there is yet another unexplored and under-diagnosed category in the PCOS spectrum of diseases: its cardio-metabolic consequences. PCOS patients are prone to these abnormalities from a very young age, increasing their morbidity and mortality rates compared to their regular counterparts. The usual pathogenesis of PCOS is a culmination of several genetic and environmental factors. Regarding its cardio-metabolic aspects, insulin resistance (IR) is said to be the single most important cause of a variety of metabolic risk factors, including type 2 diabetes mellitus (T2DM), metabolic syndrome (MetS), dyslipidemia, obesity, and hypertension (HTN), whereas a few other non-traditional factors such as C-reactive protein (CRP), carotid intima-media thickness (IMT), coronary artery calcification (CAC), and endothelial dysfunction are also said to be increased in PCOS patients, further increasing their risk of complications due to cardiovascular diseases (CVD). A timely diagnosis and adequate treatment of these risk factors by using lifestyle interventions, diet, and/or medications are essential to reduce the burden of PCOS in today's world. This article has highlighted an array of traditional and non-traditional cardio-metabolic consequences PCOS patients are prone to and their systematic pathogenesis. In addition, an outline of recommendations has been given in the pharmacological and non-pharmacological sections of this article, which may benefit doctors in managing this challenging condition.

[Contraception in the context of PCOS]

Polycystic ovary syndrome is a frequent endocrinopathy, affecting between 8% and 13% of women of childbearing age and characterized by hyperandrogenism, chronic anovulation and polycystic ovary morphology. Women with PCOS also have a higher prevalence of obesity, metabolic disorders and an increased risk of diabetes, systemic hypertension and dyslipidemia. The first-line treatment for women with PCOS who do not plan to conceive in the short term includes lifestyle changes and combined oral contraceptives, offering, in addition to contraception, endometrial protection and reduction of hyperandrogenism. Progestin-only contraceptives are recommended for women with contraindications to estrogen contained in combined oral contraceptives. Cosmetic procedures can be added to pharmacological treatment for hirsutism. Severe cases may require anti-androgen drugs which will be combined with contraception. For overweight patients with cardiometabolic risk factors, including insulin resistance or dysglycemia, metformin may also be combined with contraception. In conclusion, the choice of contraception in women with PCOS includes an approach tailored to the individual needs of each patient.

Association of Hormonal Contraceptive Use With Adverse Health Outcomes: An Umbrella Review of Meta-analyses of Randomized Clinical Trials and Cohort Studies

IMPORTANCE

Meta-analyses have reported conflicting data on the safety of hormonal contraception, but the quality of evidence for the associations between hormonal contraceptive use and adverse health outcomes has not been quantified in aggregate.

OBJECTIVE

To grade the evidence from meta-analyses of randomized clinical trials (RCTs) and cohort studies that assessed the associations between hormonal contraceptive use and adverse health outcomes among women.

DATA SOURCES

MEDLINE, Embase, and the Cochrane Database of Systematic Reviews were searched from database inception to August 2020. Search terms included hormonal contraception, contraceptive agents, progesterone, desogestrel, norethindrone, megestrol, algestone, norprogesterones, and levonorgestrel combined with terms such as systematic review or meta-analysis.

EVIDENCE REVIEW

The methodological quality of each meta-analysis was graded using the Assessment of Multiple Systematic Reviews, version 2, which rated quality as critically low, low, moderate, or high. The Grading of Recommendation, Assessment, Development and Evaluations approach was used to assess the certainty of evidence in meta-analyses of RCTs, with evidence graded as very low, low, moderate, or high. Evidence of associations from meta-analyses of cohort studies was ranked according to established criteria as nonsignificant, weak, suggestive, highly suggestive, or convincing.

RESULTS

A total of 2996 records were screened; of those, 310 full-text articles were assessed for eligibility, and 58 articles (13 meta-analyses of RCTs and 45 meta-analyses of cohort studies) were selected for evidence synthesis. Sixty associations were described in meta-analyses of RCTs, and 96 associations were described in meta-analyses of cohort studies. Among meta-analyses of RCTs, 14 of the 60 associations were nominally statistically significant (P ≤ .05); no associations between hormonal contraceptive use and adverse outcomes were supported by high-quality evidence. The association between the use of a levonorgestrel-releasing intrauterine system and reductions in endometrial polyps associated with tamoxifen use (odds ratio [OR], 0.22; 95% CI, 0.13-0.38) was graded as having high-quality evidence, and this evidence ranking was retained in the subgroup analysis. Among meta-analyses of cohort studies, 40 of the 96 associations were nominally statistically significant; however, no associations between hormonal contraceptive use and adverse outcomes were supported by convincing evidence in the primary and subgroup analyses. The risk of venous thromboembolism among those using vs not using oral contraception (OR, 2.42; 95% CI, 1.76-3.32) was initially supported by highly suggestive evidence, but this evidence was downgraded to weak in the sensitivity analysis.

CONCLUSIONS AND RELEVANCE

The results of this umbrella review supported preexisting understandings of the risks and benefits associated with hormonal contraceptive use. Overall, the associations between hormonal contraceptive use and cardiovascular risk, cancer risk, and other major adverse health outcomes were not supported by high-quality evidence.

Combined Intranasal Insulin/Saxagliptin/Metformin Therapies Ameliorate the Effect of Combined Oral Contraceptive- (COC-) Induced Metabolic Syndrome (MetS) with a Major Target on Glucose Metabolism in Adult Female Wistar Rats

Objective

To evaluate the effect of the chronic use of combined oral contraceptives (COCs: ethinyl estradiol and levonorgestrel) on the indices of metabolic syndrome in adult female Wistar rats and possible therapeutic management.

Materials and Methods

64 female Wistar rats received either distilled water, norethindrone (NOR), COC, intranasal insulin (INI), metformin (MET), saxagliptin (SAX), INI+MET, and INI+SAX. After 8 weeks of exposure to COC, the animals were sorted into the therapeutic groups. Several parameters were assayed for, such as body weight changes, fasting blood glucose (FBG) level, insulin levels, inflammatory cytokines, and glycated hemoglobin (Hb1Ac).

Results

The levels of FBG, insulin, and Hb1Ac were increased consequent upon COC treatment. Treatment with INI+SAX and INI+MET reduced significantly the levels of FBG and Hb1Ac; in addition, the level of insulin was significantly increased in the INI+MET groups (p ≤ 0.05). Serum lipid profile analysis showed a statistical reduction in high-density lipoprotein (HDL) level; this reduction was also significantly reversed in the INI+SAX group. Reduced catalase activity observed in the COC group was reversed in the INI+MET group (p ≤ 0.05). A nonsignificant increase in the level of TNF-α as a result of COC treatment was reversed by INI and INI+MET treatment. Liver GLUT4 and G-6-phosphate levels were significantly increased by COC treatment, and this effect was reversed by INI+SAX in both assays, respectively (p ≤ 0.01).

Conclusions

The use of MET and SAX in combination with INI has been shown to reverse some indices of MetS. This study proposes a clinical phase to backup and ascertain these preclinical findings.

Polycystic Ovary Syndrome, Combined Oral Contraceptives, and the Risk of Dysglycemia: A Population-Based Cohort Study With a Nested Pharmacoepidemiological Case-Control Study

OBJECTIVE

Irregular menstrual cycles are associated with increased cardiovascular mortality. Polycystic ovary syndrome (PCOS) is characterized by androgen excess and irregular menses; androgens are drivers of increased metabolic risk in women with PCOS. Combined oral contraceptive pills (COCPs) are used in PCOS both for cycle regulation and to reduce the biologically active androgen fraction. We examined COCP use and risk of dysglycemia (prediabetes and type 2 diabetes) in women with PCOS.

RESEARCH DESIGN AND METHODS

Using a large U.K. primary care database (The Health Improvement Network [THIN]; 3.7 million patients from 787 practices), we carried out a retrospective population-based cohort study to determine dysglycemia risk (64,051 women with PCOS and 123,545 matched control subjects), as well as a nested pharmacoepidemiological case-control study to investigate COCP use in relation to dysglycemia risk (2,407 women with PCOS with [case subjects] and without [control subjects] a diagnosis of dysglycemia during follow-up). Cox models were used to estimate the unadjusted and adjusted hazard ratio, and conditional logistic regression was used to obtain adjusted odds ratios (aORs).

RESULTS

The adjusted hazard ratio for dysglycemia in women with PCOS was 1.87 (95% CI 1.78-1.97, P < 0.001; adjustment for age, social deprivation, BMI, ethnicity, and smoking), with increased rates of dysglycemia in all BMI subgroups. Women with PCOS and COCP use had a reduced dysglycemia risk (aOR 0.72, 95% CI 0.59-0.87).

CONCLUSIONS

In this study, limited by its retrospective nature and the use of routinely collected electronic general practice record data, which does not allow for exclusion of the impact of prescription-by-indication bias, women with PCOS exposed to COCPs had a reduced risk of dysglycemia across all BMI subgroups. Future prospective studies should be considered for further understanding of these observations and potential causality.

An Update on Contraception in Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in reproductive-aged women, characterized by hyperandrogenism, oligo/anovulation, and polycystic ovarian morphology. Combined oral contraceptives (COCs), along with lifestyle modifications, represent the first-line medical treatment for the long-term management of PCOS. Containing low doses of estrogen and different types of progestin, COCs restore menstrual cyclicity, improve hyperandrogenism, and provide additional benefits such as reducing the risk of endometrial cancer. However, potential cardiometabolic risk associated with these agents has been a concern. COCs increase the risk of venous thromboembolism (VTE), related both to the dose of estrogen and the type of progestin involved. Arterial thrombotic events related to COC use occur much less frequently, and usually not a concern for young patients. All patients diagnosed with PCOS should be carefully evaluated for cardiometabolic risk factors at baseline, before initiating a COC. Age, smoking, obesity, glucose intolerance or diabetes, hypertension, dyslipidemia, thrombophilia, and family history of VTE should be recorded. Patients should be re-assessed at consecutive visits, more closely if any baseline cardiometabolic risk factor is present. Individual risk assessment is the key in order to avoid unfavorable outcomes related to COC use in women with PCOS.

Pharmacological Approaches to Controlling Cardiometabolic Risk in Women with PCOS

Polycystic ovary syndrome (PCOS) is characterized by elevated androgen production and subclinical changes in cardiovascular and metabolic risk markers. Total cholesterol, high-density lipoprotein (HDL) cholesterol, fasting glucose, and fasting insulin appear to increase specifically in PCOS compared with fertile women. PCOS also confers an increased risk of cardiometabolic disease in later life. Novel biomarkers such as serum’s cholesterol efflux capacity and blood-derived macrophage activation profile may assist in more accurately defining the cardiometabolic risk profile in these women. Aldosterone antagonists, androgen receptor antagonists, 5α-reductase inhibitors, and synthetic progestogens are used to reduce hyperandrogenism. Because increased insulin secretion enhances ovarian androgen production, short-term treatment with metformin and other hypoglycemic agents results in significant weight loss, favorable metabolic changes, and testosterone reduction. The naturally occurring inositols display insulin-sensitizing effects and may be also used in this context because of their safety profile. Combined oral contraceptives represent the drug of choice for correction of androgen-related symptoms. Overall, PCOS management remains focused on specific targets including assessment and treatment of cardiometabolic risk, according to disease phenotypes. While new options are adding to established therapeutic approaches, a sometimes difficult balance between efficacy and safety of available medications has to be found in individual women.

Efficacy of Treatments for Polycystic Ovarian Syndrome Management in Adolescents

Limited evidence on treatment options for polycystic ovarian syndrome (PCOS) has led to considerable variation in health care practices. We aimed to compare the effects of metformin and/or oral contraceptive pills (OCP) in combination with pioglitazone, spironolactone, flutamide, and lifestyle interventions among adolescents aged 11 to 19 years with PCOS. Literature searches were performed in Medline, Embase, and the Cochrane Central Register of Controlled Trials from database inception through December 2018, with no language restriction. Two reviewers screened titles and abstracts, assessed full text eligibility, and extracted information from eligible trials. Evidence was synthesized through network meta-analyses (NMA) using a Bayesian random-effects approach. We identified 37 randomized controlled trials, in which 2400 patients were randomized. NMA showed no statistically important difference among all interventions to improve menstrual regulation or body mass index. Moderate-quality evidence showed hirsutism scores were reduced by multiple interventions that included single and combination medications namely; lifestyle intervention, metformin, OCP, spironolactone, pioglitazone, metformin-OCP, metformin-spironolactone, and metformin-flutamide against placebo. Moderate-quality evidence showed OCP results in more dysglycemia compared to metformin (odds ratio, 2.98; 95% credible interval, 1.02-8.96), no intervention resulted in dysglycemia reduction. In conclusion, metformin and OCP as monotherapy or in combination with other interventions compared with placebo can reduce hirsutism scores, but none of these medications lead to effective menstrual cycle regulation or weight reduction. However, the use of OCP leads to worse cardiometabolic risk factors. Further research into new treatment options is urgently needed.

Current treatment for polycystic ovary syndrome: focus on adolescence

Polycystic ovary syndrome (PCOS) is the most frequent endocrine disorder in women and it is associated with an increased rate of infertility. Its etiology remains largely unknown, although both genetic and environmental factors play a role. PCOS is characterized by insulin resistance, metabolic disorders and low-grade chronic inflammation. To date, the treatment of PCOS is mainly symptomatic and aimed at reducing clinical signs of hyperandrogenism (hirsutism and acne), at improving menstrual cyclicity and at favoring ovulation. Since PCOS pathophysiology is still largely unknown, the therapeutic interventions currently in place are rarely cause-specific. In such cases, the therapy is mainly directed at improving hormonal and metabolic dysregulations typical of this condition. Diet and exercise represent the main environmental factors influencing PCOS. Thus, therapeutic lifestyle changes represent the first line of intervention, which, in combination with oral contraceptives, represent the customary treatment. Insulin resistance is becoming an increasingly studied target for therapy, most evidence stemming from the time-honored metformin use. Relatively novel strategies also include the use of thiazolidinediones and GLP1-receptor agonists. In recent years, a nutraceutical approach has been added to the therapeutic toolkit targeting insulin resistance. Indeed, emerging data support inositol and alpha-lipoic acid as alternative compounds, alone or in combination with the aforementioned strategies, with favorable effects on ovulation, insulin resistance and inflammation. Nevertheless, additional studies are required in adolescents, in order to assess the effectiveness of diet supplements in preventing negative impacts of PCOS on fertility in adult age. This review focuses on the main therapeutic options for PCOS to date.

Pharmacological and surgical treatment of nonreproductive outcomes in polycystic ovary syndrome: An overview of systematic reviews

BACKGROUND

Polycystic ovary syndrome (PCOS) affects up to 13% women and is associated with significant complications. The quality of evidence supporting the recommendations on treatment of nonreproductive outcomes in PCOS is unknown.

OBJECTIVE

To summarize and appraise the methodological quality of systematic reviews and meta-analyses evaluating pharmacological and surgical treatments for nonreproductive outcomes in PCOS.

METHODS

A literature search from MEDLINE, EMBASE, CINAHL PLUS and PROSPERO was performed from inception until 15th of September 2017. Article selection, data extraction and quality appraisal of included reviews were performed in duplicate. A narrative synthesis of the findings was conducted.

RESULTS

This overview included 31 reviews. The quality was low for 7 (23%), moderate for sixteen (52%) and high for 8 reviews (26%). Two reviews assessed psychological outcomes. Metformin improved anthropometric (7 of 10 reviews), metabolic (4 of 14 reviews) and endocrine outcomes (3 of twelve reviews). Thiazolidinediones improved metabolic (2 of 5 reviews) and endocrine outcomes (one of 5 reviews) but worsened weight gain (5 of 5 reviews). Combined oral contraceptive pill (COCP) improved clinical hyperandrogenism (2 of 2 reviews). Statins improved lipid profile (3 of 3 reviews) and testosterone level (2 of 3 reviews). There was no conclusive evidence from included systematic reviews regarding the use of other interventions.

CONCLUSIONS

There is reliable evidence regarding the use of metformin for anthropometric outcomes and COCPs for hyperandrogenism in women with PCOS but not for other interventions. There is significant gap in knowledge regarding the management of psychological outcomes in women with PCOS which needs further evaluation.

Dyslipidaemias in women using hormonal contraceptives: a cross sectional study in Mulago Hospital Family Planning Clinic, Kampala, Uganda

OBJECTIVE

To determine the prevalence and factors associated with dyslipidaemias in women using hormonal contraceptives.

DESIGN

Cross-sectional study SETTING: Mulago Hospital, Kampala, Uganda PARTICIPANTS: Three hundred and eighty-four consenting women, aged 18-49 years, who had used hormonal contraceptives for at least 3 months prior to the study.

STUDY OUTCOME

Dyslipidaemias (defined as derangements in lipid profile levels which included total cholesterol ≥200 mg/dL, high-density lipoprotein <40 mg/dL, triglyceride >150 mg/dL or low-density lipoprotein ≥160 mg/dL) for which the prevalence and associated factors were obtained.

RESULTS

The prevalence of dyslipidaemias was 63.3% (95% CI: 58.4 to 68.1). Body mass index (BMI) (PR=1.33, 95% CI: 1.15 to 1.54, p<0.001) and use of antiretroviral therapy (ART) (PR=1.21, 95% CI: 1.03 to 1.42, p=0.020) were the factors significantly associated with dyslipidaemias.

CONCLUSION

Dyslipidaemias were present in more than half the participants, and this puts them at risk for cardiovascular diseases. The high-risk groups were women with a BMI greater than 25 Kg/m² and those who were on ART. Therefore, lipid profiles should be assessed in women using hormonal contraceptives in order to manage them better.

Diagnosis and follow-up of type 2 diabetes in women with PCOS: a role for OGTT?

Polycystic ovary syndrome (PCOS) is common in premenopausal women. The majority of women with PCOS have insulin resistance and the risk of type 2 diabetes mellitus (T2D) is higher in women with PCOS compared to controls. In non-pregnant women with PCOS, glycemic status may be assessed by oral glucose tolerance test (OGTT), fasting plasma glucose (FPG) or HbA1c. OGTT has been reckoned gold standard test for diagnosing T2D, but OGTT is rarely used for diagnostic purpose in other non-pregnant individuals at risk of T2D, apart from PCOS. OGTT has questionable reproducibility, and high sensitivity of the 2-h glucose value is at the expense of relatively low specificity, especially regarding impaired glucose tolerance (IGT). Furthermore, lean women with PCOS are rarely diagnosed with T2D and only few percent of normal-weight women have prediabetes. Glycemic status is necessary at diagnosis and during follow-up of PCOS, especially in women with high risk of T2D (obesity, previous gestational diabetes (GDM)). We suggest that OGTT should be used in the same situations in PCOS as in other patient groups at risk of T2D. OGTT is indicated for diagnosing GDM; however, OGTT during pregnancy may not be indicated in lean women with PCOS without other risk factors for GDM.

Cardiovascular disease in a nationwide population of Danish women with polycystic ovary syndrome

Background

Polycystic ovary syndrome (PCOS) is associated with obesity and low grade inflammation and the risk for cardiovascular disease (CVD) could be increased in PCOS.

Methods

National register-based study including women with PCOS and no previous diagnosis of CVD, hypertension, or dyslipidemia. PCOS Denmark (N = 18,112) included women with PCOS in the Danish National Patient Register. PCOS Odense University Hospital (OUH, N = 1165) was an embedded cohort including premenopausal women with PCOS and clinical and biochemical examination. Three age-matched controls were included per patient in PCOS Denmark (N = 52,769). The main study outcome was CVD events including hypertension and dyslipidemia defined according to nationwide in- and outpatient hospital contact diagnosis codes and/or inferred from filled medicine prescriptions.

Results

The age at inclusion was median (quartiles) 29 (23–35) years and follow up was 11.1 (6.9–16.0) years. The Hazard ratio (95% CI) for development of CVD in PCOS Denmark was 1.7 (1.7; 1.8) (P < 0.001) and the total event rate of CVD was 22.6 per 1000 patient years in PCOS Denmark vs. 13.2 per 1000 patient years in controls (P < 0.001). The median age at diagnosis of CVD was 35 (28–42) years in PCOS Denmark vs. 36 (30–43) years in controls (P < 0.001). Obesity, diabetes, and infertility, and previous use of oral contraceptives were associated with increased risk of development of CVD in PCOS Denmark (P < 0.001). Women in PCOS OUH resembled women in PCOS Denmark regarding risk of CVD. Age, BMI, blood pressure, lipid status, and glycemic status predicted development of CVD in PCOS OUH.

Conclusion

The event rate of CVD including hypertension and dyslipidemia was higher in PCOS compared to controls. The risk of developing CVD must be considered even in young women with PCOS.

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.

Association of breastfeeding duration with dyslipidemia in women aged over 20 years: Korea National Health and Nutrition Examination Survey 2010-2014

BACKGROUND

The prevalence of dyslipidemia, particularly hypercholesterolemia, has been reported to increase after pregnancy and menopause in Korea. This suggests the importance of the management of dyslipidemia in women for preventing cardiovascular diseases.

OBJECTIVE

This study aimed to examine the association of breastfeeding with 5 subtypes of dyslipidemia in Korean women aged over 20 years, by using the nationally representative Korea National Health and Nutrition Examination Survey 2010-2014.

METHODS

Ordinary least square regression and ordered logistic regression analyses were used to determine the association between breastfeeding duration and dyslipidemia.

RESULTS

The likelihood of having low-density lipoprotein cholesterol (LDL-C) disorder decreased by 16% in the group that breastfed for more than 24 months (odds ratio, 0.84; 95% confidence interval, 0.75-0.95) compared with the group that did not breastfeed. The likelihood of having non-high-density lipoprotein cholesterol (non-HDL-C) disorder was significantly reduced by 25% when the breastfeeding duration was more than 24 months (odds ratio, 0.75; 95% confidence interval, 0.64-0.87). The tendency toward developing disorders of total cholesterol (TC), LDL-C, and non-HDL-C decreased as the duration of breastfeeding increased, particularly among women aged 30-39 years.

CONCLUSION

Breastfeeding duration was negatively correlated with dyslipidemia in terms of TC, LDL-C, non-HDL-C, and triglycerides. Long-term breastfeeding was associated with the prevalence of dyslipidemia-TC, LDL-C, non-HDL-C, and TG disorders, in particular.

Risks, benefits size and clinical implications of combined oral contraceptive use in women with polycystic ovary syndrome

BACKGROUND

Polycystic ovary syndrome (PCOS) is a complex condition with high risk for dyslipidemia, dysglycemia, venous thromboembolism, cardiovascular disease and metabolic syndrome. Because the combined oral contraceptive (COC) use has also been associated with impaired fasting glucose, insulin resistance and increased risk of thromboembolism disease, it is rationale to think that the combination of oral contraceptive and PCOS could make it worse or increase the risks.

OBJECTIVE

To examine the current data regarding potential additional risks and benefits of contraceptive use, highlights the major gap in knowledge for designing future studies and, when possible, suggests an adequate COC formulation for a determined PCOS phenotype.

METHODS

English-language publications reporting on the influence of COCS in the development of venous thromboembolism in PCOS patients published until 2017 were searched using PubMed, Cochrane database, and hand search of references found in consulted articles. Ranges of collected data are given; the pooled data are presented as median and first and third quartiles. Wilcoxon signed-ranks test for paired samples was used to compare before-after original data. P value was set at 0.05.

RESULTS

Most of COCs preparations significantly decrease androgens, and increase sex-hormone binding globulin. Therefore, the benefits of COCs are clear in patients with proved hyperandrogenemia. Regarding the impact of COCs on carbohydrate metabolism of PCOS subjects, the data were inconsistent but they tended to show no additional risk. Regarding lipids, most COCs consistently increased high-density lipoprotein cholesterol, triglycerides and total cholesterol concentrations but the clinical implications of these changes need additional studies.

CONCLUSION

The review showed consistent beneficial effect of COCs, particularly for hyperandrogenemic PCOS patients. The benefit size of COC's use by normoandrogenemic PCOS patients is uncertain and need more investigation. The effects of COC use on carbohydrate metabolism of women with PCOS are still unresolved since most studies are observational but the current results demonstrated that COCs do not make their levels worse and may improve insulin sensitivity. The impact of COCs on lipids of PCOS patients seems to be clearer and most preparations increase total cholesterol, high-density lipoprotein cholesterol and triglycerides. In summary, it is important to balance the potential benefits and risks of the COCs individually before prescribing them for PCOS women.

Development and Risk Factors of Type 2 Diabetes in a Nationwide Population of Women With Polycystic Ovary Syndrome

OBJECTIVE

Polycystic ovary syndrome (PCOS) is associated with insulin resistance and obesity. Prospective population-based data regarding development and possible predictors of type 2 diabetes (T2D) in PCOS are limited.

DESIGN

National Patient Register-based study.

METHODS

Patients with PCOS [PCOS Denmark and embedded cohort, PCOS Odense University Hospital (OUH)] and a control population with no previous diagnosis of T2D. PCOS OUH (N = 1,162) included premenopausal women with PCOS and standardized clinical and biochemical examination. PCOS Denmark (N = 18,477) included women with PCOS in the Danish National Patient Register. Three age-matched controls were included per patient (N = 54,680).

MAIN OUTCOME

T2D events according to diagnosis codes and filled medicine prescriptions.

RESULTS

The median (quartiles) follow-up was 11.1 (6.9 to 16.0) years. The hazard ratio (HR) with 95% confidence interval (CI) for development of T2D in PCOS Denmark was HR = 4.0 (95% CI, 3.7 to 4.3; P < 0.001), and the total event rate of T2D was 8.0 per 1000 person years in PCOS Denmark vs 2.0 per 1000 person years in controls (P < 0.001). The median age at diagnosis of T2D was 31 (26 to 37) years in PCOS Denmark vs 35 (27 to 44) years in controls (P < 0.001). In multiple regression analyses, body mass index, glycated hemoglobin, fasting blood glucose, 2-hour blood glucose, homeostasis model assessment of insulin resistance, and triglycerides were positively associated with development of T2D, whereas higher number of births was negatively associated with development of T2D.

CONCLUSION

The event rate of T2D was higher in PCOS compared with controls, and T2D was diagnosed at a younger age.

The Pharmacogenetics of Metformin in Women with Polycystic Ovary Syndrome: A Randomized Trial

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting women of reproductive age. PCOS is associated with obesity, dyslipidaemia and insulin resistance, and metformin treatment may improve such metabolic features. The effect of genetic variants in key metformin transporters, their transcriptional regulators or in metformin target genes on metformin response in women with PCOS is unclear. Associations between pharmacodynamic responses to metformin (changes in weight, lipid profile, insulin sensitivity evaluated by oral glucose tolerance testing) and polymorphisms in OCT1 (rs12208357 and rs72552763), HNF1A (rs1169288 and rs2464196), MATE1 (rs2289669 and rs2252281), MATE2-K (rs12943590) and ATM (rs11212617) were studied in 40 women with PCOS randomized to 12 months of treatment with metformin 1000 mg twice daily ± oral contraceptive pills (150 μg desogestrel + 30 μg ethinylestradiol). In the entire study population, treatment was associated with reduced weight (median weight change -2.4 kg, 25th-75th percentile -5.2 to 0.3 kg, p < 0.001) and increased triglycerides (0.2 mmol/L (0.0-0.6 mmol/L), p < 0.01) without significant changes in other lipid parameters or insulin sensitivity (insulin_AUC , glucose_AUC during OGTT). None of the evaluated polymorphisms significantly affected any treatment outcome. In conclusion, the genetic variants investigated were not crucial for the clinical response to metformin in PCOS.

Effect of oral contraceptives and/or metformin on GLP-1 secretion and reactive hypoglycaemia in polycystic ovary syndrome

CONTEXT

Insulin resistance in polycystic ovary syndrome (PCOS) may increase the risk of reactive hypoglycaemia (RH) and decrease glucagon-like peptide-1 (GLP-1) secretion. The possible effects of treatment with oral contraceptives (OCP) and/or metformin on GLP-1 secretion and risk of RH in PCOS is undetermined.

SETTING

Outpatient clinic.

PATIENTS AND INTERVENTIONS

Randomized, controlled clinical trial. Ninety women with PCOS were randomized to 12-month treatment with OCP (150 mg desogestrel + 30 mg ethinylestradiol), metformin (2 g/day) or metformin + OCP. Five-hour oral glucose tolerance tests (5-h OGTT) measuring fasting and area under the curve (AUC) for GLP-1, glucose, insulin and C-peptide were performed before and after the intervention period. Sixty-five women completed the study and 34 weight-matched healthy women were included as controls.

MAIN OUTCOME MEASURES

Changes in GLP-1, glucose, insulin and C-peptide during 5-h OGTT.

RESULTS

Fasting GLP-1 levels increased during metformin + OCP vs OCP treatment, whereas AUC GLP-1 levels were unchanged during medical treatment. The prevalence of reactive hypoglycemia increased from 9/65 to 14/65 after intervention (P < 0.01) and was more common after treatment with metformin + OCP (increase from 3/23 to 6/23, P = 0.01). Reactive hypoglycaemia was associated with higher insulin and C-peptide levels during 5-h OGTT, but was unassociated with BMI and AUC GLP-1. GLP-1 levels were comparable in PCOS vs controls. AUC GLP-1 levels were significantly lower in obese vs lean patients and were inversely associated with BMI.

CONCLUSIONS

AUC GLP-1 levels were unchanged during treatment. Increased risk of hypoglycemia during metformin + OCP could be associated with increased insulin secretion.

Impact of hormonal contraception and weight loss on high-density lipoprotein cholesterol efflux and lipoprotein particles in women with polycystic ovary syndrome

OBJECTIVE

To study the effects of oral contraceptive pills (OCP), the first-line treatment for PCOS, on high-density lipoprotein cholesterol (HDL-C) function (reverse cholesterol efflux capacity) and lipoprotein particles measured using nuclear magnetic resonance spectroscopy in obese women.

DESIGN

Secondary analysis of a randomized controlled trial (OWL-PCOS) of OCP or Lifestyle (intensive Lifestyle modification) or Combined (OCP + Lifestyle) treatment groups for 16 weeks.

PATIENTS

Eighty-seven overweight/obese women with PCOS at two academic centres.

MEASUREMENTS

Change in HDL-C efflux capacity and lipoprotein particles.

RESULTS

High-density lipoprotein cholesterol efflux capacity increased significantly at 16 weeks in the OCP group [0·11; 95% confidence interval (CI) 0·03, 0·18, P = 0·008] but not in the Lifestyle (P = 0·39) or Combined group (P = 0·18). After adjusting for HDL-C and TG levels, there was significant mean change in efflux in the Combined group (0·09; 95% CI 0·01, 0·15; P = 0·01). Change in HDL-C efflux correlated inversely with change in serum testosterone (rs = -0·21; P = 0·05). In contrast, OCP use induced an atherogenic low-density lipoprotein cholesterol (LDL-C) profile with increase in small (P = 0·006) and large LDL-particles (P = 0·002). Change in small LDL-particles correlated with change in serum testosterone (rs = -0·31, P = 0·009) and insulin sensitivity index (ISI; rs = -0·31, P = 0·02). Both Lifestyle and Combined groups did not show significant changes in the atherogenic LDL particles.

CONCLUSIONS

Oral contraceptive pills use is associated with improved HDL-C function and a concomitant atherogenic LDL-C profile. Combination of a Lifestyle program with OCP use improved HDL-C function and mitigated adverse effects of OCP on lipoproteins. Our study provides evidence for use of OCP in overweight/obese women with PCOS when combined with Lifestyle changes.

Hormonal contraception in women with polycystic ovary syndrome: choices, challenges, and noncontraceptive benefits

Polycystic ovary syndrome (PCOS) is an endocrine disorder among women of reproductive age characterized by chronic anovulation and polycystic ovary morphology and/or hyperandrogenism. Management of clinical manifestations of PCOS, such as menstrual irregularities and hyperandrogenism symptoms, includes lifestyle changes and combined hormonal contraceptives (CHCs). CHCs contain estrogen that exerts antiandrogenic properties by triggering the hepatic synthesis of sex hormone-binding globulin that reduces the free testosterone levels. Moreover, the progestogen present in CHCs and in progestogen-only contraceptives suppresses luteinizing hormone secretion. In addition, some types of progestogens directly antagonize the effects of androgens on their receptor and also reduce the activity of the 5α reductase enzyme. However, PCOS is related to clinical and metabolic comorbidities that may limit the prescription of CHCs. Clinicians should be aware of risk factors, such as age, smoking, obesity, diabetes, systemic arterial hypertension, dyslipidemia, and a personal or family history, of a venous thromboembolic event or thrombophilia. This article reports a narrative review of the available evidence of the safety of hormonal contraceptives in women with PCOS. Considerations are made for the possible impact of hormonal contraceptives on endocrine, metabolic, and cardiovascular health.

Comparison of Drospirenone- with Cyproterone Acetate-Containing Oral Contraceptives, Combined with Metformin and Lifestyle Modifications in Women with Polycystic Ovary Syndrome and Metabolic Disorders: A Prospective Randomized Control Trial

Background:

While combined oral contraceptives (COCs) are commonly used to treat polycystic ovary syndrome (PCOS), comparative data regarding metabolic effects of different progestogens on this patient population are missing. This study aimed to compare the different effects of drospirenone (DRP)-containing COCs with cyproterone acetate (CPA)-containing COCs, combined with metformin and lifestyle modifications in women with PCOS and metabolic disorders.

Methods:

Ninety-nine women with PCOS and a metabolic disorder between January 2011 and January 2013 were enrolled into this prospective randomized clinical trial. Participants were randomized into two groups such as DRP-containing COCs, and CPA-containing COCs. Participants took COCs cyclically for 6 months, combined with metformin administration (1.5 g/d) and lifestyle modifications (diet and exercise). Clinical measures and biochemical and hormone profiles were compared. Comparisons for continuous variables were evaluated with paired and unpaired Student's t-tests. The Wilcoxon signed rank test was used when the data were not normally distributed. Analysis of covariance was used to control for age, body mass index (BMI), and baseline data of each analyzed parameter when compared between the two groups.

Results:

A total of 68 patients have completed the study. The combination regimen of COCs, metformin, and lifestyle modifications in these patients resulted in a significant decrease in BMI, acne, and hirsutism scores when compared to baseline levels in both groups (P < 0.05). Blood pressure (BP) was significantly different in the CPA group when compared to baseline (75.14 ± 6.77 mmHg vs. 80.70 ± 5.60 mmHg, P < 0.01), and after 6 months of treatment, only the change in systolic BP was significantly different between the two groups (4.00 [–6.00, 13.00] mmHg vs. –3.50 [–13.00, 9.00] mmHg, P = 0.009). Fasting glucose, fasting insulin, and homeostasis model assessment-insulin resistance decreased significantly in the DRP group (5.40 ± 0.41 mmol/L vs. 5.21 ± 0.32 mmol/L, P = 0.041; 13.90 [10.50, 18.40] μU/ml vs. 10.75 [8.60, 13.50] μU/ml, P = 0.020; 3.74 [2.85, 4.23] vs. 2.55 [1.92, 3.40], P = 0.008) but did not differ between the two groups. While individual lipid profiles increased in both groups, no statistically significant difference was observed.

Conclusions:

DRP-containing COCs combined with metformin and lifestyle modifications could better control BP and correct carbohydrate metabolism in women with PCOS and metabolic disorders compared with CPA-containing COCs.

MANAGEMENT OF ENDOCRINE DISEASE: Morbidity in polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is the most prevalent endocrine condition in premenopausal women. The syndrome is characterized by hyperandrogenism, irregular menses and polycystic ovaries when other etiologies are excluded. Obesity, insulin resistance and low vitamin D levels are present in more than 50% patients with PCOS, these factors along with hyperandrogenism could have adverse effects on long-term health. Hyperinflammation and impaired epithelial function were reported to a larger extent in women with PCOS and could particularly be associated with hyperandrogenism, obesity and insulin resistance. Available data from register-based and data linkage studies support that metabolic-vascular and thyroid diseases, asthma, migraine, depression and cancer are diagnosed more frequently in PCOS, whereas fracture risk is decreased. Drug prescriptions are significantly more common in PCOS than controls within all diagnose categories including antibiotics. The causal relationship between PCOS and autoimmune disease represents an interesting new area of research. PCOS is a lifelong condition and long-term morbidity could be worsened by obesity, sedentary way of life, Western-style diet and smoking, whereas lifestyle intervention including weight loss may partly or fully resolve the symptoms of PCOS and could improve the long-term prognosis. In this review, the possible implications of increased morbidity for the clinical and biochemical evaluation of patients with PCOS at diagnosis and follow-up is further discussed along with possible modifying effects of medical treatment.

Noncontraceptive use of oral combined hormonal contraceptives in polycystic ovary syndrome-risks versus benefits

The use of steroid sex hormones for noncontraceptive benefits has been endorsed by several medical societies. In women with polycystic ovary syndrome (PCOS), hormonal contraceptives are first-line therapy for concurrent treatment of menstrual irregularity, acne, and hirsutism. The association of PCOS with obesity, diabetes, and dyslipidemia frequently brings up the debate regarding risks versus benefits of hormonal contraceptives in this population. In women with PCOS, the lack of large-scale studies evaluating the risks with varying doses of ethinyl estradiol, types of progestins, and presence of confounding factors such as obesity, smoking, and other cardiometabolic comorbidities is a significant limitation in these deliberations. Although it is important to assess the absolute risk for major morbidities including cardiovascular events, currently, there are a paucity of long-term data for these outcomes in PCOS. Most of the current studies do not suggest an increase in risk of prediabetes/diabetes, clinically significant dyslipidemia, inflammatory changes, or depressive/anxiety symptoms with oral contraceptive pill use. Screening of women with PCOS for cardiometabolic and psychiatric comorbidities is routinely recommended. This information should be used by health care providers to individualize the choice of hormonal contraceptive treatment, adequately counsel patients regarding risks and benefits, and formulate an appropriate follow-up plan.

Metabolic Effects of a Commonly Used Combined Hormonal Oral Contraceptive in Women With and Without Polycystic Ovary Syndrome

BACKGROUND

Data on combined hormonal oral contraceptives' (OCs) effects on metabolic changes in women with polycystic ovary syndrome (PCOS) have been conflicting and were predominantly based on OCs with cyproterone acetate (unavailable in the United States) Most studies did not include normal women as controls. We compared metabolic changes before and after an OC commonly used in the United States between women with and without PCOS.

METHODS

Ten PCOS and 20 control women took ethinyl estradiol 35 μg and norgestimate 0.18/0.215/0.25 mg. Fasting glucose and insulin, area-under-the-curve (AUC) glucose and insulin, insulin sensitivity (homeostatic model assessment of insulin sensitivity index [HOMA-ISI] and Matsuda index), insulinogenic index (Δinsulin0-30 minutes/Δglucose0-30 minutes), blood pressure, and lipids were evaluated at baseline and after three cycles of OC.

RESULTS

At baseline, PCOS women had lower insulin sensitivity (Matsuda index p = 0.0093, HOMA-ISI p = 0.0397), higher fasting insulin (p = 0.0495), fasting glucose (p = 0.0393), AUC insulin (p = 0.0023), and triglycerides (p = 0.0044) versus controls. Baseline AUC glucose did not differ between PCOS women and controls. After 3 months of OC use, glucose tolerance worsened in PCOS women versus controls (p = 0.0468). Higher baseline androgens were predictive of worsened glucose tolerance, and a reduction of AUC insulin during OC use. The insulinogenic index significantly decreased in PCOS women (p < 0.01), while fasting insulin and insulin resistance significantly worsened in control women.

CONCLUSION

Women with PCOS exhibited worsened glucose tolerance (demonstrated by AUC glucose) after 3 months of a commonly used OC compared with control women. Larger studies with longer follow-up should confirm these findings.

Effect of combined oral contraceptive use on serum 25-hydroxy vitamin D levels and ultrasound parameters in patients with polycystic ovary syndrome

PURPOSE

To investigate if there is an effect of combined oral contraceptive (COC) use on serum 25-hydroxy vitamin D [25(OH)D] levels in patients with polycystic ovary syndrome (PCOS).

METHODS

PCOS was defined by the 2003 Rotterdam criteria. All patients with PCOS were treated with a COC containing 0.035 mg ethinylestradiol and 2 mg cyproterone acetate for 6 months. Serum 25(OH)D levels, HOMA-IR, ovarian volume and antral follicule count were measured before and after the treatment.

RESULTS

The median 25(OH)D levels were 9.40 (range 4.40-24.50) μg/l and 7.00 (5.00-13.50) μg/l before and after COC use, respectively. Serum 25(OH)D levels decreased after the treatment; however, the difference was not statistically significant (p = 0.055).

CONCLUSION

This study seems to be the first prospective trial revealing the effect of COC use on serum 25(OH)D levels in women with PCOS. Although the decrease in serum 25(OH)D levels in patients with PCOS with the use of COC alone, did not reach to statistically significance level after 6 months treatment with COC.

Randomized Controlled Trial of Preconception Interventions in Infertile Women With Polycystic Ovary Syndrome

CONTEXT

Lifestyle modification is recommended in women with polycystic ovary syndrome (PCOS) prior to conception but there are few randomized trials to support its implementation or benefit.

OBJECTIVE

This study aimed to determine the relative efficacy of preconception intervention on reproductive and metabolic abnormalities in overweight/obese women with PCOS.

DESIGN, SETTING, AND PARTICIPANTS

This was a randomized controlled trial of preconception and infertility treatment at Academic Health Centers in women with infertility due to PCOS, age 18-40 y and body mass index 27-42 kg/m(2).

INTERVENTION

Women were randomly assigned to receive either 16 weeks of 1) continuous oral contraceptive pills (OCPs) (ethinyl estradiol 20 mcg/1 mg norethindrone acetate) ("OCP"); 2) lifestyle modification consisting of caloric restriction with meal replacements, weight loss medication (either sibutramine, or orlistat), and increased physical activity to promote a 7% weight loss ("Lifestyle"); or 3) combined treatment with both OCP and lifestyle modification ("Combined"). After preconception intervention, women underwent standardized ovulation induction with clomiphene citrate and timed intercourse for four cycles. Pregnancies were followed with trimester visits until delivery.

MAIN OUTCOME MEASURES

Weight, ovulation, and live birth were measured.

RESULTS

We consented 216 and randomly assigned 149 women (Lifestyle: n = 50; OCP: n = 49; Combined: n = 50). We achieved significant weight loss with both Lifestyle (mean weight loss, -6.2%; 95% confidence interval (CI), -7.4--5.0; and Combined (mean weight loss, -6.4%; 95% CI, -7.6--5.2) compared with baseline and OCP (both P < .001). There was a significant increase in the prevalence of metabolic syndrome at the end of preconception treatment compared with baseline within OCP (odds ratio [OR, 2.47; 95% CI, 1.42-4.27) whereas no change in metabolic syndrome was detected in the Lifestyle (OR, 1.18; 95% CI, 0.63-2.19) or Combined (OR, 0.72; 95% CI, 0.44-1.17) groups. Cumulative ovulation rates were superior after weight loss: OCP, 46%; Lifestyle, 60%; and Combined, 67% (P < .05). Live birth rates were OCP, 12%; Lifestyle, 26%; and Combined, 24% (P = .13).

CONCLUSIONS

A preconception weight loss intervention eliminates the adverse metabolic oral contraceptive effects and, compared with oral contraceptive pretreatment, leads to higher ovulation rates.

Study of lipid profile in adult women with acne

Objective

The aim of this study was to establish the lipid profile of female patients with acne in the Acne-in-Adult-Women Ambulatory Care Clinic in order to observe the prevalence of dyslipidemia in those patients.

Methods

This is a retrospective transversal study that evaluated the medical records of 416 patients who attended at the Acne-in-Adult-Women Ambulatory Care Clinic, at the Dermatology Department, Faculdade de Medicina do ABC, Santo André, São Paulo, Brazil, in the year 2012. Relevant data included age and clinical classification of acne. The lipid profile was analyzed according to the results of laboratory tests ordered during outpatient visits, which included total and fractionated cholesterol levels and triglycerides.

Results

The epidemiological study sample was of 219 patients, with ages ranging from 21 to 61 years (mean of 32.23 years). The predominant clinical grade was papule-pustule acne (grade II) with 156 patients (71%). Regarding the lipid profile of the patients, there was a high increase in total cholesterol levels in 17.35% of the cases. High-density lipoprotein levels were low in 11.42% of the patients, with normal prevalence in 194 subjects. Low-density lipoprotein levels were normal in most patients (60.27%). Very-low-density lipoprotein values were normal in almost all patients (94.06%) and increased in only 13 patients (5.94%). Only 18 patients presented high levels of triglycerides (8.22%).

Conclusion

The conclusion was that patients with grades II and III acne are more likely to have total cholesterol and low-density lipoprotein altered. A correct and early diagnosis can be an important measure for the prevention of the metabolic syndrome in these patients.

Oral contraception

Oral contraception (OC) remains a popular noninvasive, readily reversible approach for pregnancy prevention and, largely off label, for control of acne, hirsutism, dysmenorrhea, irregular menstruation, menorrhagia, and other menstrual-related symptoms. Many OC formulations exist, with generics offering lower cost and comparable efficacy. Certain medical conditions, including hypertension, migraine, breast cancer, and risk of venous thromboembolism (VTE), present contraindications. Blood pressure measurement is the only physical examination or testing needed before prescription. Although no OC is clearly superior to others, OCs containing the second-generation progestin levonorgestrel have been associated with lower VTE risk than those containing other progestins.

Approach to the patient: contraception in women with polycystic ovary syndrome

Polycystic ovary syndrome (PCOS) is a common reproductive and metabolic disorder. Patients with PCOS present with clinical signs of androgen excess (ie, hirsutism and acne), menstrual irregularities, and infertility. Combined oral contraceptive (OC) pills are the first-line medical therapy for the long-term management of PCOS. Containing a combination of estrogen and progestin, OCs restore regular menses, improve androgen excess, and provide effective contraception and protection from endometrial cancer. The benefits of hormonal contraception outweigh the risks in the vast majority of women with PCOS. However, concerns have been raised about potential adverse cardiovascular and metabolic effects of OCs. Currently available evidence indicates an increased relative risk of venous thrombosis associated with OCs varying among different formulations. Arterial thrombosis risk attributable to OCs does not appear to be significantly increased in young nonsmoking women. OC use might be associated with increased risk of diabetes in morbidly obese women with PCOS with severe insulin resistance. A tailored clinical approach to oral contraception in women with PCOS requires individualized risk stratification and management by determination of each PCOS patient's personal cardiometabolic risk profile at baseline and during follow-up. Before prescribing an OC, clinicians should document individual risk factors including age, smoking, obesity, any degree of glucose intolerance including prediabetes and diabetes, hypertension, dyslipidemia, thrombophilia, and personal or family history of a venous thromboembolic event.

Worsening hypertriglyceridemia with oral contraceptive pills in an adolescent with HIV-associated lipodystrophy: a case report and review of the literature

Abstract We report a case of a 17-year-old girl with a history of congenital human immunodeficiency virus (HIV) infection and lipodystrophy secondary to highly active antiretroviral therapy (HAART). She developed severe worsening of preexisting hypertriglyceridemia after treatment with oral contraceptive pills (OCP) for polycystic ovary syndrome. Her hypertriglyceridemia improved upon OCP discontinuation. Although it is known that estrogen combined with progestins have a negative effect on triglycerides and high-density lipoprotein (HDL) cholesterol levels, to our knowledge the association of HAART-related lipodystrophy and severe hypertriglyceridemia after OCP use has not been reported in the literature. We recommend avoiding the use of OCPs in patients with lipodystrophy due to the increased risk of worsening hypertriglyceridemia.

Fasting and post-prandial glucagon like peptide 1 and oral contraception in polycystic ovary syndrome

OBJECTIVE

We aimed to investigate whether fasting and meal regulated glucagon like peptide 1 (GLP-1) secretion are altered in patients with polycystic ovary syndrome (PCOS) compared to healty women and whether oral contraceptive use influence GLP-1 secretion dynamics in the syndrome.

DESIGN

Prospective observational study.

PATIENTS

Fourteen lean normal glucose tolerant patients with PCOS and 11 age- and body mass index (BMI)-matched healthy women.

MEASUREMENTS

Glucagon like peptide 1, glucose and insulin levels were measured during a standardized meal tolerance test and area under the curves (AUCs) were calculated. Whereas healthy controls were assessed at baseline, all tests were repeated in women with PCOS after treatment with ethinyl estradiol 30 μg/drospirenone 3 mg (EE/DRSP) for 3 months.

RESULTS

Both fasting and post-meal levels of GLP-1 were significantly reduced in women with PCOS compared to controls (P = 0·022 and P = 0·028, respectively). AUC for GLP-1 was also lower in PCOS (P = 0·012). Glucose and insulin measurements did not show a significant change between the groups. In the PCOS group, GLP-1, glucose and insulin levels did not show any change after 3 months of EE/DRSP use.

CONCLUSION

GLP-1 levels both at fasting and in response to a meal are blunted in lean women with PCOS compared to healthy women. Short term oral contraception do not alter GLP-1 secretion in PCOS. Disturbance in incretin secretion dynamics might contribute to the risk of impaired glucose tolerance and type 2 diabetes in PCOS.

Adiponectin, interleukin-6, monocyte chemoattractant protein-1, and regional fat mass during 12-month randomized treatment with metformin and/or oral contraceptives in polycystic ovary syndrome

CONTEXT

Central obesity in polycystic ovary syndrome (PCOS) is associated with increased inflammatory markers and increased risk for type 2 diabetes.

OBJECTIVE

To evaluate if improved body composition during treatment with metformin (M) vs. oral contraceptive pills (OCP) was associated with changes in circulating adiponectin, interleukin (IL)-6, and monocyte chemoattractant protein (MCP)-1.

PATIENTS AND INTERVENTIONS

Ninety patients with PCOS were randomized to 12-month treatment with M (2 g/day), M + OCP (150 mg desogestrel + 30 microgram ethinylestradiol) or OCP. Adiponectin, IL-6, MCP-1, whole body DXA scans, and clinical evaluations were performed before and after the intervention period in the 65 study completers.

MAIN OUTCOME MEASURES

Changes in inflammatory markers and changes in total and regional fat mass estimates.

RESULTS

Adiponectin, IL-6, and MCP-1 levels were unchanged during the three types of medical intervention. Treatment with M and M + OCP was superior to OCP regarding decreased regional fat mass. Baseline adiponectin and IL-6 were associated with BMI, waist, and trunk fat mass. Changes in trunk fat were significantly associated with changes in IL-6 and MCP-1 during M + OCP.

CONCLUSIONS

Long-term treatment with M alone or in combination with OCP was associated with improved body composition compared to OCP, whereas inflammatory markers were unchanged. OCP was not associated with increased inflammatory markers despite a small but significant weight gain.

Body composition is improved during 12 months' treatment with metformin alone or combined with oral contraceptives compared with treatment with oral contraceptives in polycystic ovary syndrome

CONTEXT

Central obesity in polycystic ovary syndrome (PCOS) is associated with increased inflammatory markers and increased risk for type 2 diabetes.

OBJECTIVE

The objective of the study was to evaluate whether treatment with metformin (M) or M combined with oral contraceptive pills (OCPs) resulted in a more advantageous body composition than treatment with OCP alone.

SETTING

The study was conducted at an outpatient clinic.

PATIENTS AND INTERVENTIONS

This was a randomized, controlled clinical trial. Ninety patients with PCOS were randomized to 12 months' treatment with M (2 g/d), M + OCP (150 mg desogestrel+30 μg ethinylestradiol), or OCP. Whole-body dual-energy x-ray absorptiometry scans and clinical and hormonal evaluations were performed before and after the intervention period. A total of 65 of 90 patients completed the study.

MAIN OUTCOME MEASURES

Changes in weight at 6 and 12 months and changes in regional fat mass estimates at 12 months were measured.

RESULTS

Dropout rates between intervention groups were not significantly different. Treatment with M and M+OCP were superior to OCP regarding weight and regional fat mass. The median (quartiles) weight changes during 12 months of M, M+OCP, and OCP treatment were -3.0 (-10.3; 0.6), -1.9 (-4.9; 0.1), and 1.2 (-0.8; 3.0) kg, respectively, P < .05. Upper to lower fat mass ratio was unchanged. Changes in body composition were predicted by the type of medical intervention (M, M+OCP, or OCP) and not by body mass index at study inclusion. OCP and M+OCP were superior to M regarding reduction in free T levels.

CONCLUSIONS

M treatment alone or in combination with OCP was associated with weight loss and improved body composition compared with OCP, whereas free T levels decreased during M+OCP or OCP. Combined treatment with M+OCP should be considered as an alternative to treatment with OCP alone to avoid weight gain in PCOS.

Metformin, oral contraceptives or both to manage oligo-amenorrhea in adolescents with polycystic ovary syndrome? A clinical review

The management of oligo-amenorrhea in adolescent patients with polycystic ovary syndrome (PCOS) represents an important and difficult challenge. Metformin and/or oral contraceptives (OCs) are different strategies widely proposed in these patients. The objective of the current review was to provide an overview on the use of metformin and/or OCs for the management of oligo-amenorrhea in adolescents with PCOS underlining their potential risks and benefits in order to help the clinician to choose the best patients' tailored treatment.

Hormonal contraceptive choice for women with PCOS: a systematic review of randomized trials and observational studies

INTRODUCTION

This paper provides a critical review of the data concerning the effects of combined hormonal contraceptives (CHC) for polycystic ovary syndrome (PCOS). The aim is to determine the best treatment option for each PCOS phenotype.

STUDY DESIGN

A literature search of the PubMed database was conducted for randomized clinical trials (RCTs) and observational studies published in any language prior to October 2013. Hyperandrogenism (HA) is the essential diagnostic criterion for PCOS and is frequently associated with insulin resistance (IR) or obesity. The combinations of these criteria define the different PCOS phenotypes and establish the scale of metabolic and cardiovascular risks.

RESULTS AND CONCLUSIONS

19 RCTs and eight observational studies evaluated issues related to the current objectives. CHC represent an effective and safe treatment in women with any PCOS phenotype. In HA/PCOS patients, any CHC analyzed in this review can be used for symptom relief. For patients with metabolic risk, overweight or moderate IR that does not require metformin, a vaginal contraceptive ring appears to be preferred to oral EE/DRP. In these patients, the combination of CHC and myo-inositol may be more effective in controlling endocrine and metabolic profiles. However, further research is needed to define the optimal duration and to clarify the effects of treatment on long-term metabolic outcomes. Future research should also focus on new CHC.

Polycystic ovary syndrome: current status and future perspective

Polycystic ovary syndrome (PCOS) is a widespread reproductive disorder that encompasses many associated health conditions and has an impact on various metabolic processes. PCOS is depicted by hyperandrogenism, polycystic ovaries, and anovulation. It increases the risk of insulin resistance (IR), type 2 diabetes, obesity, and cardiovascular disease. The etiology of the disease remains unclear, and the subjective phenotype makes a united diagnosis difficult among physicians. It seems to be a familial genetic syndrome caused by a combination of environmental and genetic factors. It can be linked with metabolic disorders in first-degree family members. PCOS is the cause of up to 30% of infertility in couples seeking treatment. Currently, there is no cure for PCOS. Despite the growing incidence of this syndrome, limited research has been done that encompasses the entirety of PCOS spectrum. In this review, the current status and possible future perspective will be discussed.
