Organokines and liver enzymes in adolescent girls with polycystic ovary syndrome during randomized treatments.

Polycystic ovary syndrome (PCOS) is often associated with metabolic-associated fatty liver disease (MAFLD). MAFLD has been associated with altered hepatic function, systemic dysmetabolism, and abnormal circulating levels of signaling molecules called organokines. Here, we assessed the effects of two randomized treatments on a set of organokines in adolescent girls with PCOS and without obesity, and report the associations with circulating biomarkers of liver damage, which were assessed longitudinally in the aforementioned studies as safety markers. Liver enzymes [aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glutamyl transferase (GGT)] were assessed as safety markers in previous randomized pilot studies comparing the effects of an oral contraceptive (OC) with those of a low-dose combination of spironolactone-pioglitazone-metformin (spiomet) for 1 year. As a post hoc endpoint, the organokines fibroblast growth factor-21 (FGF21), diazepam-binding protein-1 (DBI), and meteorin-like protein (METRNL) were assessed by ELISA after 6 months of OC (N = 26) or spiomet (N = 28). Auxological, endocrine-metabolic, body composition (using DXA), and abdominal fat partitioning (using MRI) were also evaluated. Healthy, age-matched adolescent girls (N = 17) served as controls. Circulating ALT and GGT levels increased during OC treatment and returned to baseline concentrations in the post-treatment phase; in contrast, spiomet treatment elicited no detectable changes in ALT and GGT concentrations. In relation to organokines after 6 months of treatment, (1) FGF21 levels were significantly higher in PCOS adolescents than in control girls; (2) DBI levels were lower in OC-treated girls than in controls and spiomet-treated girls; and (3) no differences were observed in METRNL concentrations between PCOS girls and controls. Serum ALT and GGT levels were directly correlated with circulating METRNL levels only in OC-treated girls (R = 0.449, P = 0.036 and R = 0.552, P = 0.004, respectively). The on-treatment increase in ALT and GGT levels occurring only in OC-treated girls is associated with circulating METRNL levels, suggesting enhanced METRNL synthesis as a reaction to the hepatic changes elicited by OC treatment. https://doi.org, identifiers 10.1186/ISRCTN29234515, 10.1186/ISRCTN11062950.

Adolescents diagnosed with polycystic ovary syndrome under the Rotterdam criteria but not meeting the diagnosis under the updated guideline.

What are the characteristics of adolescents diagnosed with polycystic ovary syndrome (PCOS) based on the 2003 Rotterdam criteria, but who do not meet the diagnosis according to the international evidence-based guideline? Adolescents who had features of PCOS but did not meet the evidence-based guideline adolescent criteria exhibited unfavorable metabolic profiles compared to controls and shared considerable metabolic and hormonal features with adolescents who did meet the adolescent criteria. The international evidence-based PCOS guideline recommended that ultrasound should not be used for the diagnosis of PCOS in girls with a gynecological age of <8 years. Thus far, few studies have evaluated the clinical characteristics of the girls diagnosed with PCOS based on the Rotterdam criteria but who do not meet the diagnosis according to the updated guideline. This is a retrospective study, and subjects attended for care from 2004 to 2022. Adolescent girls with PCOS diagnosed according to the 2003 Rotterdam criteria and healthy controls. All participants were between 2 and 8 years since menarche. Of the 315 girls diagnosed with PCOS according to the Rotterdam criteria, those with irregular menstruation (IM)/hyperandrogenism (HA)/polycystic ovary (PCO), IM/HA, HA/PCO, and IM/PCO phenotypes accounted for 206 (65.4%), 30 (9.5%), 12 (3.8%), and 67 (21.3%) participants, respectively. According to the evidence-based guideline, 79 girls (25.1%) with the HA/PCO or IM/PCO phenotypes were not diagnosed with PCOS, and aligned to the international guideline; they were designated as the 'at-risk' group. As expected, the girls meeting the evidence-based guideline adolescent criteria showed the worst metabolic profiles (degree of generalized or central obesity, frequency of insulin resistance, prediabetes or diabetes, and metabolic syndrome) and higher hirsutism scores than the at-risk group or controls. Approximately 90% of the at-risk group were not overweight or obese, which was similar to the controls. However, they showed worse metabolic profiles, with higher blood pressure, triglyceride, and insulin resistance parameters than controls; furthermore, these profiles were similar to those of the girls meeting the adolescent criteria. The at-risk group showed similarly elevated serum LH levels and LH/FSH ratio with the girls meeting adolescent criteria. We could not evaluate hormonal or ultrasound parameters in controls. Compared to the conventional Rotterdam criteria, the recent international evidence-based guideline-avoiding ultrasound in PCOS diagnosis in adolescents-still gives the opportunity to identify young girls at risk, aligned to the findings in this study. A practical approach to this adolescent population would involve establishing IM or HA (with ultrasound not indicated) and designating 'at-risk' PCOS status with regular check-ups for newly developed or worsening PCOS-related symptoms or metabolic abnormalities, with subsequent reassessment including ultrasound or anti-Müllerian hormone, once 8 years post-menarche. No funding was received in support of this study. The authors have no conflicts of interest to disclose. N/A.

Association of anti-Müllerian hormone and insulin resistance in adolescent girls with polycystic ovary syndrome.

Insulin resistance (IR) is confirmed as an important feature among polycystic ovary syndrome (PCOS) patients. Anti-Müllerian hormone (AMH), a vital marker of ovarian dysfunction, is proposed for inclusion in the diagnosis of PCOS in adolescents. We sought to investigate the relationship between the AMH level and IR in Chinese girls with PCOS. 92 girls with PCOS aged 14-18 years were enrolled and divided into 2 subgroups: PCOS with IR group (n = 25) and PCOS without IR group (n = 67). A homeostasis model assessment-insulin resistance (HOMA-IR) value ≥ 2.5 was defined as IR. Clinical data and biochemical indexes were compared between the 2 groups. Multivariate logistic regression analysis and multivariate linear regression analysis were performed to determine which clinical variables were independently associated with IR and AMH level, respectively. PCOS girls with IR had higher levels of AMH than those of PCOS girls without IR (p < 0.01). Moreover, body mass index, triglyceride, and AMH values were shown to be independent risk factors for HOMA-IR after multivariate analysis. Meanwhile, age, insulin, and follicle-stimulating hormone levels were significantly related to AMH levels in those girls. Our findings show that AMH is an independent determinant of IR in PCOS adolescents, and the fasting insulin level is closely associated with the AMH level, which indicates that the AMH pathway might play a role in the development of IR in PCOS adolescents. The interaction between AMH and IR in PCOS girls warrants further large-scale evaluation.

Effects of AIDiet intervention to improve diet quality, immuno-metabolic health in normal and overweight PCOS girls: a pilot study

This study was conducted in two groups of girls with PCOS (polycystic ovary syndrome) categorized as slim (group N) and overweight-to-obese (group Ov/Ob). The study's primary outcome was to assess the impact of a 12-week anti-inflammatory diet (AIDiet) intervention, without energy deficit, on daily diet quality improvement, evaluated according to the KIDMED index. The secondary outcome was improving inflammatory, redox, hormonal, and metabolic statuses. In the study, which was completed by 13 girls from the Ov/Ob group and 19 girls from the N group, a significant improvement in the mean KIDMED score was obtained. Moreover, the intervention significantly improves concentration of total antioxidant capacity (TAC), fasting insulin, and the homeostatic model assessment for insulin resistance (HOMA-IR) index, in the Ov/Ob group, while both groups experienced a reduction in the concentration of interleukin (IL)-1 and IL-6, tumour necrosis factor (TNF-α), and androstenedione. The AIDiet intervention effectively improved the quality of the subjects' diets, which was associated with the improvement of hormonal and immuno-metabolic markers. However, these changes in normal-weight patients were observed regardless of body weight reduction. ClinicalTrials.gov Identifier NCT04738409.

Polycystic Ovary Syndrome in Girls With Type 2 Diabetes

Source: Cioana M, Deng J, Nadarajah A, et al. Prevalence of polycystic ovary syndrome in patients with pediatric type 2 diabetes a systematic review and meta-analysis. JAMA Netw Open. 2022;5(2):e2147454. doi:10.1001/jamanetworkopen.2021.47454Investigators from multiple institutions conducted a meta-analysis to estimate the prevalence of polycystic ovary syndrome (PCOS) in girls with type 2 diabetes (T2D). For the meta-analysis, systematic search procedures were used to identify studies in which the prevalence of PCOS in girls diagnosed with T2D when they were ≤18 years old was estimated. Studies included could have cross-sectional, retrospective, or prospective cohort designs, if they had a minimum sample of 10 patients. No specific criteria for the diagnosis of PCOS were required. The prevalence of PCOS in each included study was determined, and a pooled prevalence was calculated. A secondary analysis that included studies in which specific criteria were required for the diagnosis of PCOS also was conducted. For studies with the available data, the prevalence of PCOS among girls with T2D from different racial groups was calculated.The authors screened 722 articles to identify 6 studies that met the inclusion criteria; 5 of these were retrospective cohort studies. Data on 470 girls were included in the meta-analysis. The mean age at diagnosis of T2D among participants in the included studies ranged from 12.9 years to 16.1 years. Overall, the pooled prevalence of PCOS among adolescent females with T2D was 19.58% (95% CI, 12.02%, 27.14%). Three studies required a history of persistent oligomenorrhea and clinical and/or biochemical hyperandrogenism for a diagnosis of PCOS. Among 87 girls with T2D included in these studies, the pooled prevalence of PCOS was 24.04% (95% CI, 15.07%, 33.01%). There were 2 studies in which the prevalence of PCOS by race was reported; reported prevalence was 17% among 36 white females, 23.10% in Indian adolescent females (N = 195), and 2.0% in indigenous females in Canada (N = 64).The authors conclude that approximately 1 in 5 girls with T2D had PCOS.Dr. Fechner has disclosed no financial relationship relevant to this commentary. This commentary does not contain a discussion of an unapproved/investigative use of a commercial product/device.It is not surprising that 1 in 5 girls with T2D have PCOS, as insulin resistance with hyperinsulinemia increases androgen production by the ovary, leading to PCOS.1 While the diagnosis of PCOS in adult women requires 2 of 3 criteria: androgen excess, oligo/anovulation or polycystic ovaries,2 the presence of polycystic ovaries on ultrasound and anovulatory symptoms may be normal in the early post-menarchal years. Thus, a history of anovulation and an ultrasound with polycystic ovaries may be normal during the period after menarche. A consensus statement on the pathophysiology, diagnosis, and treatment of PCOS in adolescence in 2017 suggested the diagnostic criteria of clinical and/or biochemical hyperandrogenism with irregular menses/oligomenorrhea at least 2 years post-menarche.3As in adults, it is important to exclude other etiologies such as non-classic congenital adrenal hyperplasia, hyperprolactinemia, and thyroid disease. PCOS has many of the same co-morbidities as T2D. In addition, there is increased infertility and increased risk of endometrial cancer as well as possible increased androgen exposure to the female fetus leading to ambiguous genitalia in the fetus.2 Treatment of PCOS overlaps T2D treatment, with lifestyle management to lose weight as a primary intervention. Adolescents with PCOS may also benefit from the use of an oral contraceptive to decrease androgens and improve acne, hirsutism, anovulatory symptoms, and to prevent pregnancy. Metformin for those unsuccessful with lifestyle management may also benefit both PCOS and T2D management.3It is important to gather menstrual history and look for signs of hyperandrogenism in females with T2D as PCOS appears to be a relatively common morbidity in girls with T2D.

Melatonin in the saliva of adolescent girls with polycystic ovary syndrome

Background. The formation of polycystic ovary syndrome (PCOS) and the manifestation of its clinical manifestations often begin in adolescence. In recent years, one of the new and modern areas in the study of reproductive dysfunction is the problem of melatonin on the gonadotropic function of the pituitary gland (ovariogenesis). The purpose of the study was to determine the level of melatonin in the saliva of adolescent girls with PCOS. Materials and methods. A single-center prospective simple randomized study was conducted with 23 patients aged 14–18 years (inclusive) with PCOS. The control group consisted of 25 girls of the same age without gynecological status violations. Determination of melatonin levels in saliva was performed by high performance liquid chromatography with tandem mass spectrometry (HPLC-MS). Before salivation during the day and throughout the saliva collection period, patients excluded caffeine, alcohol, and exercise, did not smoke for one hour before collection, did not brush their teeth, did not floss, rinsed their mouths, and did not chew gum. Results. There were no significant differences in the age of the girls in the main group and the comparison group (16.70±0.11 years in the main group and 16.90±0.14 years in the comparison group, p&gt;0.05). The most common symptoms of PCOS in girls were: hypomenstrual syndrome (86.9%), dermopathy (82.6%) and hirsutism (60.8%). Girls with PCOS had significantly higher melatonin levels in saliva (03:00) (28.89 [18.17; 46.53] pg/ml) compared to girls in the comparison group (12.07 [11.56; 16.27] pg/ml, p&lt;0.01). A probable difference in melatonin levels in saliva depending on age has not been established. Conclusions. The results of the study indicate a violation of hormonal balance in polycystic ovary syndrome, in particular an increase in melatonin levels, which indicates the need to determine it in the process of diagnosis and treatment.

Body Image and Self- Esteem in girls with Polycystic Ovary Syndrome (PCOS): The Indian Scenario

Polycystic Ovary syndrome is common endocrine disorder generally found in girls of reproductive age which adversely cause metabolic, endocrine, reproductive and mental health of young girls. It has long-term consequences associated with it like diabetes, hypertension, endometrial cancer and coronary artery disease. The prevalence of PCOS is rising in India, which are undergoing rapid transitions due to westernization. Appearance related issues e.g., hirsutism, acne, and obesity, the body image of PCOS women especially young girls (who are more concern for their body) have become more challenging. Thus the girls with PCOS have greater body dissatisfaction and low self esteem as it is exclusively based on body image. Negative perception of body image among PCOS girls include dissatisfaction with appearance, perceived loss of femininity, feeling less sexually attractive, and self-consciousness about appearance. However, due to limited literature on psychosocial impact for girls diagnosed with PCOS, especially in developing countries like India, its significance is still unfathomed. Keeping in mind the importance of body image and self esteem on physical appearance in young girls in the Indian culture the present review was undertaken.

Prevalence of Polycystic Ovary Syndrome in Patients With Pediatric Type 2 Diabetes

The prevalence of pediatric type 2 diabetes (T2D) is increasing globally. Girls with T2D are at risk of developing polycystic ovary syndrome (PCOS), but the prevalence of PCOS among girls with T2D is unknown. To determine the prevalence of PCOS in girls with T2D and to assess the association of obesity and race with this prevalence. In this systematic review and meta-analysis, MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Web of Science: Conference Proceedings Citation Index-Science, and the gray literature were searched from inception to April 4, 2021. Two reviewers independently screened for studies with observational study design that recruited 10 or more participants and reported the prevalence of PCOS in girls with T2D. Risk of bias was evaluated using a validated tool, and level of evidence was assessed using the Oxford Centre for Evidence-Based Medicine criteria. A random-effects meta-analysis was performed. This study follows the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline. The main outcome of this systematic review was the prevalence of PCOS in girls with T2D. Secondary outcomes included assessing the associations of obesity and race with PCOS prevalence. Of 722 screened studies, 6 studies involving 470 girls with T2D (mean age at diagnosis, 12.9-16.1 years) met the inclusion criteria. The prevalence (weighted percentage) of PCOS was 19.58% (95% CI, 12.02%-27.14%; I2 = 74%; P = .002). Heterogeneity was moderate to high; however, it was significantly reduced after excluding studies that did not report PCOS diagnostic criteria, leading to a calculated prevalence (weighted percentage) of 24.04% (95% CI, 15.07%-33.01%; I2 = 0%; P = .92). Associations with obesity and race could not be determined because of data paucity. In this meta-analysis, approximately 1 in 5 girls with T2D had PCOS, but the results of this meta-analysis should be considered with caution because studies including the larger numbers of girls did not report the criteria used to diagnose PCOS, which is a challenge during adolescence. The associations of obesity and race with PCOS prevalence among girls with T2D need further evaluation to help define at-risk subgroups and implement early assessment and treatment strategies to improve management of this T2D-related comorbidity.

Causes and Consequences of Polycystic Ovary Syndrome: Insights From Mendelian Randomization.

Although polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women of reproductive age, risk factors that may cause the syndrome are poorly understood. Based on epidemiologic studies, PCOS is thought to cause several adverse outcomes such as cardiovascular disease; however, the common presence of comorbidities such as obesity may be responsible for such associations, rather than PCOS in and of itself. To overcome the limitations of observational studies, investigators have employed Mendelian randomization (MR), which uses genetic variants to interrogate causality between exposures and outcomes. To clarify causes and consequences of PCOS, this review will describe MR studies involving PCOS, both as an exposure and as an outcome. The literature was searched using the terms "Mendelian randomization," "polycystic ovary syndrome," "polycystic ovarian syndrome," and "PCOS" (to May 2021). MR studies have suggested that obesity, testosterone levels, fasting insulin, serum sex hormone-binding globulin concentrations, menopause timing, male-pattern balding, and depression may play a causal role in PCOS. In turn, PCOS may increase the risk of estrogen receptor-positive breast cancer, decrease the risk of endometrioid ovarian cancer, and have no direct causal effect on type 2 diabetes, coronary heart disease, or stroke. The accumulation of genome-wide association studies in PCOS has enabled multiple MR analyses identifying factors that may cause PCOS or be caused by PCOS. This knowledge will be critical to future development of measures to prevent PCOS in girls at risk as well as prevent complications in those who have PCOS.

Effects of serum irisin, neuregulin 4, and weight management on obese adolescent girls with polycystic ovary syndrome.

The study is aimed at investigating the association of serum irisin, neuregulin 4 (NRG4), and anti-müllerian hormone (AMH) with adolescent obesity with polycystic ovary syndrome (PCOS) and the efficacy of weight management interventions. Serum levels of irisin, NRG4, AMH, sex steroid hormone, body mass index (BMI), serum insulin, and C-peptide were measured in 52 obese adolescent girls with PCOS (PCOS group) and 43 obese adolescent girls without PCOS (non-PCOS group). The levels of AMH, NRG4, serum irisin, sex steroid hormones, BMI, serum insulin, and C-peptide were evaluated in obese PCOS girls before and after one year weight management. The levels of AMH, serum insulin, NRG4, and total testosterone of PCOS group were significantly higher than those of non-PCOS group. On the contrary, serum irisin and serum C-peptide in PCOS group were significantly lower than that in non-PCOS group. The levels of fat mass, percent body fat, total testosterone, AMH, NRG4, and serum insulin in the obese girls with PCOS showed significant decreases compared with before weight management intervention. On the contrary, after one year of body weight management intervention, serum irisin and serum C-peptide was significantly increased. Adolescent obesity complicated with PCOS is significantly associated with glucose and lipid metabolism and sex steroid hormone disorders, but the exact pathophysiological and clinical features are highly variable. Weight management intervention can significantly improve the clinical symptoms and hematological indicators, serum irisin and NRG4 can be used as two essential biomarkers for evaluating weight management.

Dietary and Physical Activity Habits in Adolescent Girls with Polycystic Ovary Syndrome (PCOS)-HAstudy.

The role of inappropriate lifestyle in the etiology of polycystic ovary syndrome (PCOS) and its metabolic and reproductive complications has attracted much attention in recent years; however, most studies involve adult patients. Thus, the study aimed to compare dietary patterns, physical activity, metabolic, anthropometric and inflammatory markers of 14–18-year-old girls with and without PCOS (n = 61 and n = 35, respectively) as well as to assess correlations between concentrations of metabolic and inflammatory markers and macronutrient intake and to identify the independent predictors of PCOS, related to diet and physical activity (PA). Compared to the control group, PCOS girls consumed significantly more total fat (p = 0.0005), including both saturated (SFA) (p = 0.03), monounsaturated (MUFA) (p = 0.0003) and polyunsaturated fatty acids (PUFA) (p = 0.01). A significantly higher percentage of PCOS patients consumed high and medium glycemic index (GI) foods (p = 0.03) and represented a low level of PA, both during school and in leisure time (41.67 vs. 6.06%; p = 0.0001 and 32.79 vs. 5.71%; p = 0.003, respectively). The PCOS group had also significantly higher waist circumference (WC), C-reactive protein (CRP) (p = 0.01), LDL cholesterol (p = 0.01), fasting insulin (p = 0.002) and HOMA-IR (p = 0.006) levels. There was an inverse correlation between fiber intake and fasting insulin, (p = 0.0002, r = −0.37), HOMA-IR (p = 0.0004, r = −0.35), WC (p = 0.029; r = −0.222) and a positive relationship between high and medium GI diet and insulin concentration (p = 0.003; r = 0.3). An increase of 10 g/day in total fat intake per day increases the probability of PCOS by 1.4 times. If the SFA or MUFA intakes increase by 10 g, the probability of PCOS increase 1.7-fold and 2.5-fold, respectively. The consumption of foods with a medium GI raises the probability of PCOS by more than 3 times, after adjusting for age. The odds ratio decreased for the moderate and high PA at school/work and in leisure time. Further research in girls with PCOS is needed to test whether low GI and dietary fatty acid reduction combined with increased PA is effective in the nonpharmacological treatment and prevention of PCOS complications.

Predictive factors of polycystic ovary syndrome in girls with precocious pubarche.

ObjectiveThe aim of this study is to clarify, in girls with premature pubarche (PP), the influence of premature androgenization on the prevalence of polycystic ovary syndrome (PCOS).Design and patientsNinety-nine PP girls, 63 who developed PCOS and 36 who did not develop PCOS, were retrospectively included. Clinical, anthropometric, and metabolic parameters were evaluated at the time of diagnosis of PP and after 10 years from menarche to find predictive factors of PCOS.ResultsYoung females with PP showed a PCOS prevalence of 64% and showed a higher prevalence of familial history of diabetes (P = 0.004) and a lower prevalence of underweight (P = 0.025) than PP-NO-PCOS. In addition, girls with PP-PCOS showed higher BMI (P < 0.001), waist circumference (P < 0.001), total testosterone (P = 0.026), visceral adiposity index (VAI) (P = 0.013), total cholesterol (P < 0.001), LDL-cholesterol (P < 0.001), non-HDL cholesterol (P < 0.001) and lower age of menarche (P = 0.015), ISI-Matsuda (P < 0.001), DIo (P = 0.002), HDL cholesterol (P = 0.026) than PP-NO-PCOS. Multivariate analysis showed that WC (P = 0.049), ISI-Matsuda (P < 0.001), oral disposition index (DIo) (P < 0.001), VAI (P < 0.001), total testosterone (P < 0.001) and LDL-cholesterol (P < 0.001) are independent predictive factors for PCOS in girls with PP.ConclusionsOur study established a strong association between multiple risk factors and development of PCOS in PP girls. These risk factors are predominantly related to the regulation of glucose, lipid, and androgen metabolism. Among these factors, WC, ISI-Matsuda, DIo, VAI, total testosterone, and LDL-cholesterol predict PCOS.

The relative deficit of GDF15 in adolescent girls with PCOS can be changed into an abundance that reduces liver fat

A prime concern of young patients with Polycystic Ovary Syndrome (PCOS) is the control of body adiposity, given their tendency to gain weight and/or their difficulty to lose weight. Circulating growth-and-differentiation factor-15 (GDF15) facilitates the control of body weight via receptors in the brainstem. C-reactive protein (CRP) and insulin are endogenous GDF15 secretagogues. We hypothesised that PCOS in non-obese adolescents is characterised by low concentrations of circulating GDF15, when judged by the degree of CRP and insulin drive. GDF15 was added as a post-hoc endpoint of two previously reported, randomised studies in non-obese adolescent girls with PCOS (N = 58; 60% normal weight; 40% overweight) who received either an oral oestroprogestogen contraceptive (OC), or a low-dose combination of spironolactone-pioglitazone-metformin (SPIOMET) for 1 year; subsequently, all girls remained untreated for 1 year. Adolescent girls with regular menses (N = 20) served as healthy controls. Circulating GDF15, CRP and fasting insulin were assessed prior to treatment, and halfway the on- and post-treatment years. Pre-treatment, the absolute GDF15 concentrations were normal in PCOS girls, but their relative levels were markedly low, in view of the augmented CRP and insulin drives. OC treatment was accompanied by a near-doubling of circulating GDF15 (on average, from 296 to 507 pg/mL) and CRP, so that the relative GDF15 levels remained low. SPIOMET treatment was accompanied by a 3.4-fold rise of circulating GDF15 (on average, from 308 to 1045 pg/mL) and by a concomitant lowering of CRP and insulin concentrations towards normal, so that the relative GDF15 levels became markedly abundant. Post-OC, the relatively low GDF15 levels persisted; post-SPIOMET, the circulating concentrations of GDF15, CRP and insulin were all normal. BMI remained stable in both treatment groups. Only SPIOMET was accompanied by a reduction of hepato-visceral fat (by MRI) towards normal. In conclusion, early PCOS was found to be characterised by a relative GDF15 deficit that may partly explain the difficulties that young patients experience to control their body adiposity. This relative GDF15 deficit persisted during and after OC treatment. In contrast, SPIOMET treatment was accompanied by an absolute and a relative abundance of GDF15, and followed by normal GDF15, CRP and insulin concentrations. The present findings strengthen the rationale to raise the concentrations of circulating GDF15 in early PCOS, for example with a SPIOMET-like intervention that attenuates low-grade inflammation, insulin resistance and ectopic adiposity, without necessarily lowering body weight.Clinical trial registries: ISRCTN29234515 and ISRCTN11062950.

Relation between Inflammation, Oxidative Stress, and Macronutrient Intakes in Normal and Excessive Body Weight Adolescent Girls with Clinical Features of Polycystic Ovary Syndrome.

The impact of diet on inflammation and oxidative stress (OS) in girls with polycystic ovary syndrome (PCOS) is unknown. Therefore, our study aimed to investigate, in PCOS girls, whether certain macronutrient intakes can be associated with these disturbances. For this purpose, 59 PCOS participants (aged 14–18 years) were recruited to this study and divided into two subgroups: overweight/obese—Ov/Ob group (n = 22) and normal weight—N group (n = 37). Nutrition was assessed using a 3-day food record. The studied markers were total antioxidant capacity (TAC), malondialdehyde (MDA), C-reactive protein (CRP), tumor necrosis factor α (TNF-α), and interleukins 1 and 6 (IL-1 and IL-6). We found plant protein intake inversely correlated with IL-6 (p = 0.007; r = −0.557), TNF-α (p = 0.006; r = −0.564), MDA (p = 0.01; r = −0.539) in the Ov/Ob group and with TAC (p = 0.021; r = −0.38) in the N group. Inverse correlations in the Ov/Ob group were observed between protein intake and IL-6 (p = 0.031; r = −0.461), TNF- α (p = 0.043; r = −0.435); carbohydrates and IL-6 (p = 0.037; r = −0.448), MDA (p = 0.045; r = −0.431); fiber and IL-6 (p = 0.025; r = −0.475). A positive relationship between cholesterol intake and CRP concentration (p = 0.038; r = 0.342) was also found in the N group. These findings revealed that inflammation and OS are increased in Ov/Ob girls with decreased plant protein intake and low carbohydrates in the diet. Moreover, inflammation may be increased by cholesterol intake in slim PCOS girls. On the other hand, decreased intake of fiber and total protein intake increased inflammation.

Androgen and Anti-Mullerian Hormone Concentrations at Term in Newborns and Their Mothers with and without Polycystic Ovary Syndrome.

Objectives: The aetiology of polycystic ovary syndrome (PCOS) is not particularly mapped; however, a complex interaction of various factors, such as genetic, environmental and intrauterine factors, can be assumed. Experimental animal studies and clinical observations support the hypothesis that developmental programming by excess intrauterine steroid is relevant. The aim of the study was to investigate whether mothers with and without PCOS exhibit different androgen and anti-Mullerian hormone (AMH) levels at the end of pregnancy and how maternal hormone levels are reflected in their offspring. Methods: Between March 2013 and December 2015, we performed a prospective cross-sectional study at the Medical University of Graz. We included 79 women with PCOS according to the ESHRE/ASRM 2003 definition and 354 women without PCOS, both with an ongoing pregnancy ≥37 + 0 weeks of gestation, who gave birth in our institution. Primary outcome parameters were the levels of maternal and neonatal androgens (testosterone, free testosterone, androstenedione) and AMH at delivery. Results: Androgen levels in female offspring of PCOS and non-PCOS women at birth did not differ, while maternal hormone levels differed significantly. Androgen levels in PCOS boys were significantly higher when compared to levels in PCOS girls. Discussion: Our findings do not support the hypothesis that maternal androgen excess contributes to elevated androgen concentrations in the female offspring. Nevertheless, the effects of the increased androgen concentrations in mothers on their offspring have to be investigated in future studies.

Low-Dose Spironolactone-Pioglitazone-Metformin Normalizes Circulating Fetuin-A Concentrations in Adolescent Girls with Polycystic Ovary Syndrome.

Background Fetuin-A is a glycoprotein produced in the liver and related to metabolic syndrome; fetuin-A secretion is divergently regulated in different pathological conditions. In girls with polycystic ovary syndrome (PCOS), insulin sensitization results in a more favorable endocrine-metabolic outcome than oral contraception; we assessed whether those differences are underscored by changes in circulating fetuin-A. Methods Fetuin-A concentration endocrine-metabolic markers and hepatovisceral fat were measured longitudinally in 35 PCOS girls [age, 16 yr; body mass index (BMI), 23 kg/m2] randomized to receive either oral contraception [ethinylestradiol-levonorgestrel (n = 18)] or a low-dose combination of spironolactone, pioglitazone, and metformin (SPIOMET, n = 17) over 12 months. Healthy adolescent girls (age- and BMI-matched) were used as controls (n = 25). Results Pretreatment fetuin-A serum levels in PCOS girls were lower than those in controls. After 12 months on treatment, fetuin-A raised to control levels only in the SPIOMET subgroup (P = 0.009, versus oral contraception); this increase was paralleled by a healthier metabolic profile with less hepatic fat (by MRI); baseline serum fetuin-A as well as the changes over 12 months was inversely related to hepatic adiposity. Conclusions A low-dose combination of insulin sensitizers and an antiandrogen—but not oral contraception—normalizes fetuin-A levels in adolescent girls with PCOS. This trial is registered with ISRCTN29234515.

Glutathione S-transferase (GST) polymorphism could be an early marker in the development of polycystic ovary syndrome (PCOS) - an insight from non-obese and non-insulin resistant adolescents.

It has been supposed that endocrine disturbances might be responsible for polycystic ovary syndrome (PCOS)-associated oxida-tive stress, with special emphasis on hyperandrogenism. Considering the potential relationship between hyperandrogenism and increased free radical production, parameters of oxidative stress were determined in non-obese normoinsulinemic adolescent girls newly diagnosed with PCOS. Nitrotyrosine, thiol group concentrations, glutathione peroxidase, and superoxide dismutase activities were determined under fasting conditions and during oral glucose tolerance test (OGTT) in 35 PCOS patients and 17 controls. Insulin resistance was assessed by the homeostasis model (HOMA-IR), HOMA β, insulinogenic index (IGI), Matsuda insulin sensitivity index (ISI), and AUC for glucose. Glutathione S-transferases (GSTs) polymorphisms were determined by PCR. Under fasting conditions, no significant difference of oxidative stress parameters was found between PCOS and controls. Acute hyperglycaemia during OGTT induced significant alteration in parameters of oxidative protein damage in PCOS patients. Alteration in nitrotyrosine concentrations correlated with testosterone, DHEAS, androstenediones, FAI, and LH, while changes in thiol groups cor-related with DHEAS. Significant inverse association was found between LH and ISI, as well as AUC glucose and thiol groups. PCOS girls, carriers of GSTM1-null genotype, had significantly lower testosterone in comparison to ones with GSTM1-active genotype. PCOS girls exhibited high free radical production together with unchanged antioxidant enzymatic capacity, independently from obesity and insulin resistance. Based on associations between oxidative stress parameters and testosterone, DHEAS, and androsten-edione, it can be suggested that increased free radical production, probably as a consequence of hyperandrogenaemia, is an early event in the development of PCOS.

Impaired Lipolysis, Diminished Fat Oxidation, and Metabolic Inflexibility in Obese Girls With Polycystic Ovary Syndrome.

Metabolic flexibility reflects the ability to switch from lipid to carbohydrate oxidation during insulin stimulation manifested in increased respiratory quotient (RQ). Little is known about adipose tissue metabolism and metabolic flexibility in adolescent girls with polycystic ovary syndrome (PCOS). We investigated whole-body lipolysis, substrate oxidation, and metabolic flexibility in obese girls with PCOS vs obese girls without PCOS. Twenty-one obese girls with PCOS and 21 obese girls without PCOS were pair-matched for age and race. Body composition, abdominal visceral adipose tissue (VAT), sex hormones, lipid profile, and adiponectin were measured. Whole-body lipolysis ([2H5]glycerol turnover), RQ, and substrate oxidation (indirect calorimetry) were evaluated during fasting and a hyperinsulinemic-euglycemic clamp together with assessment of insulin sensitivity (IS). Despite similar body mass index and percent body fat, girls with PCOS vs girls without PCOS had lower fasting lipolysis and fat oxidation, less increase in RQ during hyperinsulinemia with impaired suppression in lipolysis and lipid oxidation, and lower IS. In multiple regression, the best predictors of metabolic flexibility were [using clinical parameters: adiponectin, fasting triglycerides, and insulin (R2 = 0.618, P < 0.0001); using research parameters: IS, VAT, and baseline RQ (R2 = 0.756, P < 0.0001)]. Obese girls with PCOS vs obese girls without PCOS have decreased lipid mobilization, diminished fat oxidation, and metabolic inflexibility. Whether this metabolic phenotype of adipose tissue dysfunction, which is conducive to fat accretion, plays a role in the induction and maintenance of obesity in adolescent girls with PCOS remains to be determined.

High Prevalence of Polycystic Ovary Syndrome in Type 1 Diabetes Mellitus Adolescents: Is There a Difference Depending on the NIH and Rotterdam Criteria?

Background: Polycystic ovary syndrome (PCOS) is more frequently observed in type 1 diabetes mellitus (T1DM) adult women than in nondiabetic women. No such prevalence has yet been studied in adolescent girls with T1DM. Aim: The aim of this study was to evaluate the prevalence of PCOS in adolescent girls with T1DM and to determine the clinical and hormonal features associated with the disorder. Methods: A cross-sectional study of 53 adolescent girls (gynecological age >2 years) referred for routine evaluation for T1DM was conducted. We diagnosed PCOS using the National Institutes of Health (NIH) and Rotterdam criteria. Results: 26.4 and 47.9% of adolescents had PCOS according to NIH (NIH-PCOS) and Rotterdam (Rotterdam-PCOS) criteria. 66.7% of NIH-PCOS adolescents had a complete phenotype associated with hyperandrogenism, oligomenorrhea, and polycystic ovarian morphology, unlike only 33.3% of the Rotterdam-PCOS adolescents. A family history of type 2 diabetes mellitus (T2DM) was more frequent in PCOS than in non-PCOS girls, whichever criteria were used. Late pubertal development and a T1DM diagnosis close to puberty were factors associated with NIH-PCOS. Conclusion: Adolescents with T1DM had a high prevalence of PCOS. More differences between PCOS and non-PCOS patients were found using the NIH criteria, suggesting that clinical characteristics might be more accurate for diagnosing PCOS in girls with T1DM. A family history of T2DM is associated with a high risk of PCOS.

Metabolic Outcomes, Bone Health, and Risk of Polycystic Ovary Syndrome in Girls with Idiopathic Central Precocious Puberty Treated with Gonadotropin-Releasing Hormone Analogues

Background/Aims: Gonadotropin-releasing hormone analogues (GnRHa) represent the gold standard treatment for central precocious puberty (CPP). We aimed to assess the effects of GnRHa treatment on metabolic outcomes, bone status, and polycystic ovary syndrome (PCOS) prevalence in young girls with idiopathic CPP (ICPP). Methods: We enrolled 94 ICPP girls who were at least 2 years after menarche and had already attained adult height at the time of the study: 56 previously treated with depot triptorelin (3.4 ± 0.6 years) and 38 untreated. Auxological parameters, lipid profile, homeostatic model assessment of insulin resistance (HOMA-IR), bone state, and prevalence of PCOS were assessed. Results: The 2 groups were similar for body mass index (BMI) and waist circumference. HOMA-IR, dehydroepi­androsterone sulfate, and Δ4-androstenedione were higher in the treated than in the untreated subjects (p < 0.001). Significant differences were found for amplitude-dependent speed of sound (p < 0.03) and bone transmission time z-scores (p < 0.01). The prevalence of PCOS was higher in the treated than in the untreated subjects (p < 0.04). Conclusion: GnRHa therapy is associated with hyperandrogenism and an increase in insulin resistance and PCOS prevalence, but not with increased BMI or lipid profile alterations. Long-term evaluations at the time of expected peak bone mass achievement are needed to understand the persistent or transient nature of subtle bone abnormalities.
