Filter by:Polycystic Ovary Syndrome (PCOS) affects 10% of all women, and it usually co-exists with high levels of male pattern hormones (also termed androgens). Women with PCOS are at increased risk of metabolic complications such as diabetes, non-alcoholic fatty liver disease, high blood pressure and heart disease. However, very little is understood about how androgen excess results in increased metabolic complications observed in women with PCOS. The main aims of the REFUEL PCOS study are to compare markers of energy metabolism in women with PCOS to those without PCOS. This will allow the investigators to better understand metabolic risk by examining the relationship between androgen excess and energy metabolism. Skeletal muscle is an important site of energy metabolism, and emerging theories are that androgen excess impairs skeletal muscle energy balance and increases the risk of complications. Based on these emerging theories, the investigators want to investigate the effects of androgens on muscle energy metabolism. The investigators will also examine whether certain blood and urine result patterns can help identify differences in muscles energy metabolism and which women are at the highest risk of metabolic complications. This research will give insight into the metabolic risk associated with PCOS and treat and, where possible, prevent the development of metabolic disease in affected women.
The goal of this study is to assess response to kisspeptin as well as the baseline patterns of luteinizing hormone (LH) secretion in individuals with polycystic ovarian syndrome (PCOS).
Chronic inflammation is the core of Polycystic ovary syndrome (PCOS), and obesity and overweight further exacerbate the level of inflammation in the peripheral circulation and ovarian tissue in PCOS patients. Metformin is a classic endocrine drug for the treatment of PCOS, but its clinical response rate is only about 40%. Our previous published study (Diabetes Obes Metab, 2022) observed that the new hypoglycemic drug SGLT-2 inhibitor can significantly improve the clinical symptoms of patients with insulin resistance PCOS, and the clinical efficacy is not inferior to metformin, but its specific mechanism of action is not clear. Recent studies have shown that SGLT-2 significantly attenuates the activation of the Nod-like receptor protein 3 (NLRP3) inflammasomes and the secretion of IL-1β in patients with type 2 diabetes mellitus at high risk of cardiovascular disease. Based on the above research background, this project will combine clinical research and mechanism exploration to solve the following two problems: 1. whether SGLT2 inhibitor can further improve the clinical efficacy of PCOS patients compared to metformin; 2. mechanistic studies further clarify whether SGLT2 inhibitors improve inflammatory symptoms by modulating NLRP3 inflammosomes in the treatment of polycystic ovary syndrome;
Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder characterized by hyperandrogenism, insulin resistance, and ovulatory dysfunction. One of the diagnostic criteria for PCOS is the presence of polycystic ovaries, which are enlarged ovaries with multiple follicles on ultrasound. However, the mechanisms that lead to the development of polycystic ovaries in PCOS are not completely understood. One potential area of investigation is the role of ovarian innervation in the pathophysiology of PCOS. Therefore, the aim of this study is to evaluate the ovarian innervation in PCOS patients through ovarian biopsy sampling.
According to World Health Organization (WHO), in 2010, Polycystic Ovarian Syndrome (PCOS) affected approximately 116 million women worldwide (3.4% of the population). It has been considered one of the most common causes of female infertility and the most common endocrine disorder. The standard diagnosis for the syndrome dates back to international conferences organized by the National Institutes of Health (NIH) in 1990 and the Rotterdam European Society of Human Reproduction and Embryology/ American Society for Reproductive Medicine (ESHRE/ASRM) sponsored PCOS consensus workshop group in 2003 and 2004. Clinical manifestations of the disease may include menstrual irregularities, amenorrhea, ovulation-related infertility, polycystic ovaries, and signs of androgen excess such as acne and hirsutism. This condition may also lead to chronic diseases such as obesity, type 2 diabetes (T2D), dyslipidaemia, and cardiovascular events. Despite the increasing knowledge concerning PCOS, the global picture of the disorder is deficient in a number of geographic regions. Understanding the global prevalence will help to better assess the public health and economic implications of PCOS in Trinidad, allow for improved screening methods, help elucidate the underlying factors and foster improved understanding of the molecular mechanisms in improving the evolutionary process.
The goal of this observational study is to know the prevalence of PCOS among economically productive and reproductive age women from Medellín and the Valle de Aburrá, Colombia. The main questions it aims to answer are: 1. What is the phenotypic distribution of PCOS detected in women seeking medical attention as a requirement for employment in Medellín and the Valle de Aburrá, Colombia? 2. What is the effect of environmental factors, such as geographical location and diet, and biological factors (such as obesity and ethnicity/race) on the prevalence and phenotype of PCOS in this populatión? Participants will undergo anthropometric measurements and physical examination for hirsutism, acne, alopecia, acanthosis nigricans, and thyroid enlargement. During the initial visit, a transvaginal or transabdominal pelvic ultrasonography will be performed. A sample of venous blood will be collected in plain tubes for serum cryopreservation and for immediate glucose estimation. Some participants will be rescheduled for a second evaluation visit for additional assessment when they have a possible PCOs.
In this study, the researchers are trying to learn more about the relationship between Polycystic Ovary Syndrome and Obstructive Sleep Apnea (OSA). Obstructive Sleep Apnea is a sleep-related breathing disorder that involves a decrease or complete stop in airflow. 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.
The primary purpose of the PCOS Indirect and Intangible Economic Buren study is to estimate the economic costs of having PCOS in terms of quality of life and work productivity. The population will include individuals with a clinical diagnosis of PCOS, individuals self-diagnosed with PCOS, individuals with symptoms of PCOS (e.g., hirsutism, irregular menstrual cycles), and demographic-matched controls without PCOS. This study is a sub-study of The PCOS Challenge Study.
This study aims to assess the association of Anti-Müllerian hormone (AMH) with polycystic ovarian syndrome, premature ovarian insufficiency and fertility. The main objectives include the following: 1. To study the level of serum AMH in women with PCOS and to evaluate the utility of serum AMH in the diagnosis of PCOS. 2. To evaluate the level of serum AMH in women with POI and to evaluate the utility of serum AMH in the management of POI. 3. To evaluate the associations of basal AMH level with FSH level and AFC respectively for women undergoing ART treatment. 4. To determine the optimal regimen of gonadotropin for ovarian stimulation for women undergoing ART treatment. 5. To evaluate the predictive value of serum AMH in reproductive outcomes including oocyte quality, embryo quality, pregnancy loss, clinical pregnancy and live birth rate in women undergoing ART treatment.
Chronic inflammation in polycystic ovary syndrome (PCOS) may be the result of dysregulation of cytokine production (due to insulin resistance, excess visceral fat and hyperandrogenemia), i.e., overproduction of pro-inflammatory factors (e.g. TNF, IL-1, IL-6) in relation to anti-inflammatory ones (IL-10). This condition may be an important link between obesity and insulin resistance, which is crucial in the etiopathogenesis of the syndrome. However, it is not known whether it results from the tendency to accumulate adipose tissue or is a feature of the syndrome itself. Concomitant endocrinopathies, i.e. obesity, dyslipidemia, insulin resistance, diabetes and thyroid diseases, may additionally influence the activity of chronic inflammation. There is no data indicating the relationship between chronic inflammation and PCOS phenotypes, the severity of metabolic disorders, ovarian reserve and the influence of thyroid function on its activity in PCOS.
