Prevalence of Hyperandrogenism in Type 1 Diabetes

Type 1 DiabetesPolycystic Ovary Syndrome4 more

The investigators aim to estimate the prevalence of functional ovarian hyperandrogenism [idiopathic hyperandrogenism, idiopatic hirsutism, and polycystic ovary syndrome (PCOS)] in adult patients with type 1 diabetes (T1DM) in an observational cross-sectional study. Study population is comprised of premenopausal adult women with a diagnosis of T1DM, consecutively recruited from a Diabetes outpatient clinic at a tertiary hospital in Spain, Europe.

HyperandrogenismPolycystic Ovary Syndrome1 more

The purpose of this study is to determine if, in mid- to late pubertal girls with hyperandrogenism (HA), androgen-receptor blockade (spironolactone) alone normalizes sleep-wake luteinizing hormone (LH) pulse frequency (primary endpoint) and overall LH and follicle-stimulating hormone secretion (secondary endpoints).

DAISy-PCOS Phenome Study - Dissecting Androgen Excess and Metabolic Dysfunction in Polycystic Ovary...

Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) affects 10% of all women and usually presents with irregular menstrual periods and difficulties conceiving. However, PCOS is also a lifelong metabolic disorder and affected women have an increased risk of type 2 diabetes, high blood pressure, and heart disease. Increased blood levels of male hormones, also termed androgens, are found in most PCOS patients. Androgen excess appears to impair the ability of the body to respond to the sugar-regulating hormone insulin (=insulin resistance). The investigator has found that fat tissue of PCOS patients overproduces androgens and that this can result in a build-up of toxic fat, which increases insulin resistance and could cause liver damage. In a large cohort of women registered in a GP database, the study team have found that androgen excess increases the risk of fatty liver disease. The aim is to identify those women with PCOS who are at the highest risk of developing metabolic disease, which would allow for early detection and potentially prevention of type 2 diabetes, high blood pressure, fatty liver and cardiovascular disease. The investigator will assess clinical presentation, androgen production and metabolic function in women with PCOS to use similarities and differences in these parameters for the identification of subsets (=clusters) of women who are at the highest risk of metabolic disease. The investigator will do this by using a standardised set of questions to scope PCOS-related signs and symptoms and the patient's medical history and measure body composition and blood pressure. This standardised recording of a patient's clinical presentation (=clinical phenotype) is called Phenome analysis. The investigator will collect blood and urine samples for the systematic measurement of steroid hormones including a very detailed androgen profile (=steroid metabolome analysis) and of thousands of substances produced by human metabolism (=global metabolome analysis). Phenome and metabolome data will then undergo integrated computational analysis for the detection of clusters predictive of metabolic risk.

Body Fat as Determinant of Female Gonadal Dysfunction

Polycystic Ovary SyndromeHypothalamic Amenorrhea

Reproduction requires from women enough energy depots to warrant an adequate nutritional supply to the fetus. Hence, adipose tissue is able to communicate with female hypothalamic-pituitary-ovary axis. The hypothesis of the project is that abnormalities in the quantity (absolute and relative to lean body mass), distribution and/or function of adipose tissue are associated with functional forms of female gonadal dysfunction in predisposed women, in a spectrum of anomalies that go from hypothalamic amenorrhea to the polycystic ovary syndrome (PCOS). To challenge this hypothesis, the investigators will study 5 groups of 10 women each: women with exercise-associated hypothalamic amenorrhea, women without ovulatory dysfunction that exercise equally, non-hyperandrogenic patients with PCOS, hyperandrogenic patients with PCOS, and healthy control women comparable to those with PCOS. The aims of the study will be: Primary objective: To identify novel signalling factors originating from adipose tissue and muscle using targeted and nontargeted evaluation of the proteome and of gene expression of superficial subcutaneous fat, deep subcutaneous fat (which mimics visceral adipose tissue) and skeletal muscle. Secondary objectives: To study the serum adipokine profile - including those identified by the primary objective - and circulating gut hormones during fasting and after a glucose load in the 5 groups of women, and their associations with sexual hormones and body fat distribution. To study body composition and body fat distribution in these women and their relationships with: 2.1, Sex steroid profiles. 2.2. Classic cardiovascular risk factors: carbohydrate metabolism, lipid profiles and blood pressure. 2.3 Markers of low-grade chronic inflammation. 2.4. Oxidative stress markers. 2.5. Cardiovascular autonomic function. 2.6. Surrogate markers of subclinical atherosclerosis. 2.7. Circulating concentrations of endocrine disruptors. 2.8. Oral and gut microbiome. The results will provide a better understanding of the mechanisms linking body energy depots with the female reproductive axis and, hopefully, the identification of potential biomarkers for the diagnosis and treatment of the disorders studied here.

Comparison of the Euploid Rate of Blastocyst Between PPOS and GnRH Antagonist Protocol in Women...

Preimplantation Genetic TestingProgestin-primed Ovarian Stimulation2 more

This randomized trial aims to compare the euploid rate of blastocysts between PPOS (progestin-primed ovarian stimulation) and GnRH (gonadotrophin releasing hormone) antagonist protocols in patients with PCOS (polycystic ovary syndrome) undergoing PGT-A (preimplantation genetic testing for aneuploidy). Infertile women with PCOS will be recruited for study after explanation and counseling if they fulfill the inclusion criteria and do not have the exclusion criteria. Eligible women will be randomised into one of the two groups: Antagonist group: Women will receive antagonist once subcutaneously daily from day 6 of ovarian stimulation till the day of the ovulation trigger. PPOS group: Women will receive oral MPA (medroxyprogesterone acetate)10mg qd from Day 3 till the day of ovulation trigger. The primary outcome is the euploidy rate of blastocysts.

Multidisciplinary Diagnosis and Treatment of Polycystic Ovary Syndrome

Polycystic Ovary Syndrome

The investigators collected clinical data and serum samples of patients with polycystic ovary syndrome (PCOS) in this study, used statistical software such as SPSS for date analysis, and used experimental techniques such as ELISA and flow cytometry to detect serum samples, aiming to explore the relationship between the body anthropometry, skin conditions, psychosomatic status, diet, sleep, exercise, glucose and lipid metabolism, gonadal hormones, and body fat distribution in patients with polycystic ovary syndrome, and to discovery new biomarkers. Multidisciplinary exploration of the mechanisms of disease occurrence and development, the establishment of a PCOS multicenter, multidisciplinary and multidimensional clinical research database, combined with the established statistical analysis strategy for big data and analysis, to promote the realization of more accurate personalized medicine.

PCOS (Polycystic Ovary Syndrome)Semaglutide

To investigate the efficacy of semaglutide in obese infertile women of childbearing age with polycystic ovary syndrome (PCOS), we design this prospective, randomized, open and controlled study. 75 obese infertile PCOS patients will be recruited and randomized into three groups: metformin, semaglutide and metformin+semaglutide, on the basis of calorie-restricted diet and physical exercise. All subjects will be treated for 12 weeks, and then stop taking the drug for at least 8 weeks to initiate ovulation induction or ovulation induction combined with artificial insemination. All subjects will be followed up for 24 weeks for pregnancy outcome. The primary endpoint of the study is the percentage of weight loss at 12 weeks of treatment. The secondary endpoints include HOMA-IR and androgen levels at 12 weeks of treatment, ovulation rate at 24 weeks of follow-up, clinical pregnancy rate and cumulative pregnancy rate, and depression, anxiety, diet and quality of life scores at 12 weeks of treatment.
