A Prospective, Multicenter, Randomized, Pivotal Study of the May Health System in Transvaginal Ablation of Ovarian Tissue under Ultrasound Guidance in Women with Infertility due to Polycystic Ovary Syndrome

Glucose Profiles in Women With Polycystic Ovary Syndrome

Polycystic ovary syndrome is a very common condition that is associated with metabolic complications. Patients with polycystic ovary syndrome exhibit insulin resistance and are at greater risk to develop type 2 diabetes. This syndrome is heterogeneous, classified according to 4 phenotypes (A-D). It seems that certain phenotypes are less exposed to insulin resistance and metabolic complications. However, only a few studies have evaluated the glucose profile according to phenotype. New technologies now make it possible to monitor glucose levels continuously. The aim of this project is to evaluate glucose profile parameters using continuous glucose monitoring, and to compare these profiles according to different PCOS phenotypes.

Berberine Phytosome for Signs and Symptoms of Polycystic Ovary Syndrome (PCOS)

This multicenter, randomized, controlled clinical trial aims to evaluate the effectiveness of berberine phytosome supplementation in improving signs and symptoms associated with polycystic ovary syndrome (PCOS). Women presenting with clinical features suggestive of PCOS, including hirsutism, acne, menstrual irregularities, and overweight, will be enrolled. Participants will be randomly assigned to one of three groups: (1) berberine phytosome supplementation in women not previously taking inositol, (2) berberine phytosome supplementation in women already taking inositol for at least three months, or (3) a control group receiving lifestyle advice without supplementation. The intervention will consist of berberine phytosome 550 mg once daily for 12 weeks. The study will evaluate changes in clinical manifestations associated with hyperandrogenism and metabolic dysfunction, including hirsutism, acne severity, body mass index, and metabolic parameters. The results will provide evidence on the potential role of berberine phytosome supplementation in improving clinical manifestations related to PCOS.

Study of the Effect of a Nutritional Supplement on Microbiota, Metabolic Control, Inflammatory Profile, and Quality of Life in Patients With Polycystic Ovary Syndrome.

Polycystic Ovary Syndrome (PCOS) is a complex endocrine-metabolic disorder characterized by elevated androgen levels due to ovarian overproduction. Although the pathophysiology of PCOS is not fully understood, it is estimated that insulin resistance (IR) occurs in 70-80% of PCOS cases, which may contribute to hyperandrogenism in affected women. Women with PCOS and IR are more likely to develop metabolic syndrome, increasing the risk of diabetes, cardiovascular diseases, lipid profile deterioration, elevated inflammation levels, and greater oxidative stress. The symptoms of PCOS are varied and differ among patients. Common symptoms include androgenic alopecia, hirsutism, acne, abdominal fat accumulation, and fertility issues. These physical manifestations and related problems have been associated with reduced quality of life and self-esteem in these women. The symptoms of PCOS can be improved through lifestyle changes aimed at enhancing insulin sensitivity, such as proper nutrition and regular physical exercise. Some supplements, such as a combination of Myo-inositol and D-chiro-inositol in a 40:1 ratio, are being used to support the management of PCOS because they appear to improve insulin sensitivity, as well as reduce underlying inflammation and oxidative stress. To determine whether nutritional intervention combined with inositol supplementation improves PCOS symptoms, various variables will be analyzed to assess improvements in oxidative stress markers, inflammation, lipid profile, hormonal profile, and microbiota. Additionally, if the metabolic profile improves, it is hypothesized that this could also enhance quality of life and self-esteem.

Multidisciplinary Diagnosis and Treatment of 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.

The purpose of this study is to find out why some people with obstructive sleep apnea have higher levels of insulin resistance, and the investigators will study the role of hypoxia (low levels of oxygen in the blood at night) in insulin resistance and see if insulin resistance improves during your treatment with CPAP.

Light Fasting Diet and Magnesium in Polycystic Ovary Syndrome (PCOS)

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders in women of reproductive age, which is associated with hormonal imbalances, dyslipidemia, chronic inflammation, and increased oxidative stress, and can increase the risk of cardiovascular and metabolic diseases. Evidence suggests that nutritional interventions play an important role in improving metabolic outcomes in these patients. This study is a randomized, triple-blind, controlled clinical trial designed to investigate the effect of a light fasting diet combined with magnesium supplementation on lipid profile, lipid peroxidation (malondialdehyde), and C-reactive protein (CRP) levels in women with PCOS. In this study, 46 eligible women were randomly divided into two groups receiving a light fasting diet with magnesium supplementation or placebo, and changes in biochemical and anthropometric indices were evaluated before and after 8 weeks of intervention.

Weight Cycling on Hyperandrogenemia and Insulin Resistance in Polycystic Ovary Syndrome

This study prospectively includes PCOS patients with normal weight and overweight/obesity, closely follows up and intensively manages them, and observes the level and distribution of weight reduction achieved by patients after lifestyle intervention (high-protein diet for weight loss). Additionally, it aims to provide reference for setting weight loss targets for future PCOS patients by comparing the differences in clinical improvement among patients achieving different degrees of weight reduction (\<2% \[equivalent to no weight loss\], 2-5%, 5-10%, ≥10%) at different time points (3 months, 6 months) following dietary intervention. Furthermore, this study will compare the differences in reproductive and metabolic marker improvements between baseline PCOS patients experiencing weight rebound, those who successfully lost weight, and those who experienced weight rebound. This will help explore the impact of weight cycling on PCOS-related manifestations. Finally, at a genetic level, the study will analyze potential mechanisms underlying different outcome indicators by comparing differences in metagenomics, transcriptomics, and metabolomics among patient groups. Ancillary/Nested Sub-study (12-week Precision Nutrition Trial): Within the WHIP cohort, we will conduct a nested, prospective interventional sub-study to evaluate the efficacy of an insulin-resistance-phenotype-guided precision dietary prescription versus a standard guideline-based energy-restricted diet. Eligible participants are women with PCOS and insulin resistance enrolled in the cohort. The sub-study lasts 12 weeks with assessments at baseline and week 12. Primary endpoints include change in HOMA-IR and change in the core11 metabolic risk composite. Secondary endpoints include changes in gonadotropins (FSH, LH), sex steroid hormones (e.g., estradiol, progesterone), and patient-reported symptom scores.

The aim of this study is to see the associations of metabolic responses of metformin with single nucleotide polymorphisms (SNPs) (rs628031 and rs2282143) of solute carrier family 22 member 1 (SLC22A1) gene in women with polycystic ovary syndrome (PCOS). This prospective clinical study will be conducted in the department of Endocrinology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from February 2023 to September 2024 over a period of two years. A total of at least 100 women with PCOS (18 - 35 years) diagnosed based on International Evidence-based Guideline for PCOS 2018, will be included consecutively by convenient sampling. After taking informed written consent, relevant clinical history will be taken and physical examinations will be done at baseline. Following a run in phase of three weeks, patients will visit thrice after 1, 12 \& 24 weeks of metformin maintenance therapy with a window period of 14 days both ways. Blood samples will be collected in fasting state at baseline and after 24 weeks of treatment to measure glycemic status, lipid profile, fasting insulin, c-peptide and detection of SLC22A1 gene (rs628031 and rs2282143) polymorphisms. Glucose will be measured by glucose oxidase method, lipids by glycerol phosphate dehydrogenase peroxidase method, insulin by chemiluminescent microparticle immunoassay, c-peptide by enzyme-linked immunosorbent assay (ELISA) and genetic analysis of rs628031 and rs2282143 by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).

Evaluation of the Venous Thrombotic Biological Profile of Different PCOS Phenotypes: French Cross-sectional Study

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder of women of childbearing age. PCOS can be individualized into several phenotypes, taking into account in particular the presence of hyperandrogenism, insulin resistance and BMI. Hyperandrogenism and insulin resistance appear to be important factors in the development of cardiovascular cardiovascular disease. In addition, patients frequently use anti-androgenic and/or contraceptive treatments contraceptives, such as combined hormonal contraception (CHC), the use of which is associated with an increased cardiovascular and thrombo and venous thrombosis (VTE). A meta-analysis published in 2020 by Gariani et al. based on three large studies, estimated the risk of VTE in women with PCOS after adjustment for obesity and hormone therapy. This risk was significantly higher compared with women without PCOS (pooled OR 1.89, CI95% 1.60-2.24). No study has looked specifically investigated the risk of VTE according to different PCOS phenotypes. Such data would be very useful in clinical practice, as it would enable monitoring, contraceptive treatment and anti-androgenic anti-androgen treatment according to the PCOS phenotype, while limiting risks. Assessing the differences PCOS phenotypes is limited by the large sample size required. required. VTE is a rare event in women of childbearing age, and the number of PCOS phenotypes is high. PCOS phenotypes. Intermediate markers of VTE risk are used in these situations. These markers are thrombin generation tests (notably ETP) and their sensitivity to activated protein C (nAPCsr) and thrombomodulin (nTMsr), as well as sex-hormone binding globulin (SHBG).

Body Fat as Determinant of Female Gonadal Dysfunction

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: 1. 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. 2. 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.
