SGLT2 Inhibitors in Treating Patients With PCOS

Polycystic Ovary Syndrome

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: whether metformin plus SGLT2 inhibitor can further improve the clinical efficacy of PCOS patients compared to metformin plus placebo; mechanistic studies further clarify whether SGLT2 inhibitors improve inflammatory symptoms by modulating NLRP3 inflammosomes in the treatment of polycystic ovary syndrome;

PCOS and US Cavitation

PCOS (Polycystic Ovary Syndrome) of Bilateral Ovaries

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Women with this syndrome may have infrequent menstrual periods or amenorrhea and excess androgen levels. The ovaries develop numerous small follicles and fail to ovulate on a regular basis, with subsequent subfertility in those women that wish to conceive. Recent research stated that interventions aiming to improve QoL among infertile women with PCOS should focus on alleviating infertility-related stress, especially among women with high BMI. So, the purpose of this study is to investigate the effect of ultrasound cavitation combined with aerobic exercise on menstrual irregularity and infertility related stress in women having PCOS.

PriskA Pilot Study

Polycystic Ovary Syndrome

Background of the study: With a prevalence up to 15%, polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age. Women with PCOS present with diverse features, including reproductive features such as irregular menstrual cycles, subfertility, hirsutism and pregnancy complications, metabolic features such as obesity, insulin resistance, metabolic syndrome, pre-diabetes, type 2 diabetes and cardiovascular factors, and psychological features such as anxiety and depression. Because of the reproductive, metabolic and cardiovascular risk factors it is important to screen and inform these women. However, up to 70% of the affected women remain undiagnosed. In academic hospitals (tertiary care) the diagnosis PCOS will rarely be missed by gynecologists. However, in peripheral hospitals or for internal medicine physicians, PCOS and its criteria are less well known. Therefore, the PCOS risk algorithm (PriskA), a digital tool to use in the assessment of PCOS in patients with signs and symptoms of PCOS, is developed. To exclude patients with a WHO I status, the tool exclude women with low Luteinizing Hormone (LH) and low Follicle-Stimulating Hormone (FSH) in advance. Women with LH and FSH within the normal range will be used in the algorithm for further assessment. The algorithm uses clinical data including age, BMI and information about irregular menstrual cycle in combination with anti-Mullerian hormone (AMH), testosterone and Sex Hormone Binding Globulin (SHBG) to generate a risk score ranging from 0-1. Women having a risk score below 0.2 are considered having a low risk of having PCOS, women with a risk score 0.2-0.8 are considered having a moderate risk of having PCOS and women with a risk score above 0.8 have a high risk of having PCOS. Objective of the study: In this study we aim to assess the validity of the PriskA algorithm to diagnose PCOS in a pilot study with patients presenting with signs and symptoms of PCOS. The study also aims to collect information on the user experience from the clinicians and to provide useful information to support the design of a validation study. Study design: This study will be a prospective, mono-center observational pilot study and it will be conducted at the Department of Reproductive Endocrinology at the Erasmus University Medical Center Rotterdam, the Netherlands. We estimate that the study will be completed within one year. Study population: Women with symptoms of PCOS who are referred to the Department of Reproductive Endocrinology at the Erasmus University Medical Center Rotterdam, and are undergoing a standardized screening (COLA screening, which stands for: (menstrual) Cycle problems, Oligomenorrhea and Amenorrhea). The COLA screening is part of standard clinical care. Women with one or more symptoms of PCOS will be included in the study. Women who eventually getting the diagnosis PCOS by standard screening will be labelled as cases and women who have one PCOS symptom and did not get the diagnosis PCOS will be labelled as controls. Primary study parameters/outcome of the study: The validity of the PriskA tool to diagnose PCOS, by assessing the sensitivity and specificity of the risk probabilities of 0.2 and 0.8.Parameters that will be used: Testosterone level in serum (using Elecsys using Cobas 6000) SHBG level in serum (using Elecsys using Cobas 6000). AMH level in serum (using Elecsys using Cobas 6000). LH level in serum (using Elecsys using Cobas 6000) FSH level in serum (using Elecsys using Cobas 6000) Cycle information Age BMI Secondary study parameters/outcome of the study: A secondary study parameter is to assess the number (percentage) and characteristics of patients with a PriskA score between 0.2-0.8. Characteristics will include: menstrual cycle information, age, BMI, serum LH, serum FSH, serum AMH, serum testosterone, serum SHBG, serum progesterone, serum estradiol, total follicle count, PCOS phenotype (if applicable), WHO diagnosis or other endocrinological diagnosis. Another secondary parameter is the user experience of the PriskA tool. This will be collected from every user by a questionnaire. Questionnaires will be collected from every used when he/she completed 20 patients during the study.

Liraglutide and Metformin Combination on Weight Loss, Metabolic - Endocrine Parameters and Pregnancy...

Polycystic Ovary SyndromeObesity2 more

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age and one of the leading causes of infertility. PCOS and obesity affect up to 12.5% - 48.3% Asian women, increase incidence of impaired glucose tolerance, type 2 diabetes and aggravate insulin resistance, cause ovulatory dysfunction and menstrual disorders, and negatively impact outcomes of Assited Reproductive Technology (ART), with higher miscarriage rate when receiving ART. Weight loss decrease insulin resistance and hyperandrogenism, improve ovulation rate and menstrual cycle, significantly higher conception and live birth rates. Weight loss prior to IVF procedures has been associated with significantly improved pregnancy rates (PR) and live birth rates. Furthermore, a decreased number of IVF cycles required to achieve a pregnancy has also been reported after weight loss interventions. Based on the principles of fetal programming, improving a lifestyle before conception might lead to improved longterm health of the offspring. Studies on the effect of anti-obesity medication combined with lifestyle changes on body weight and composition and metabolic - endocrine parameters and pregnancy rate in obese women diagnosed with PCOS are lacking. There is a growing need to develop pharmacologic interventions to improve metabolic function in women with polycystic ovary syndrome (PCOS).

Effect of Hyperandrogenism on IVF Outcomes in PCOS Patients

PCOS (Polycystic Ovary Syndrome) of Bilateral Ovaries

Ovulatory dysfunction affects 18 to 25% of infertile women, the most common identifiable condition is polycystic ovarian syndrome (PCOS). The most frequent symptoms of PCOS are oligo-anovulation, hyperandrogenism and polycystic ovary appearance. Hyperandrogenism is the main contributor that affects oocyte and embryo quality and decreases the success rates in PCOS patients undergoing IVF treatments. The aim of this study is to determine the effect of hyperandrogenism as an independent factor on IVF success rates and oocyte/embryo quality in PCOS patients undergoing IVF.

Letrozole Versus Hormonal Preparation in Frozen Cycles of PCOS Patients.

Frozen Embryo TransferPolycystic Ovarian Disease4 more

One of the indications of freezing is to reduce the risk of ovarian hyperstimulation syndrome particularly in polycystic ovarian disease (PCOS) women. Very few RCTs addressed the issue of optimizing the endometrium for a frozen cycle. Interestingly, Letrozole for ovarian stimulation showed significantly better reproductive outcome when compared with hormone replacement therapy (HRT) cycle. In addition, HRT cycle has been associated with higher miscarriage rate when compared with natural cycle frozen embryo transfer. Nevertheless, there is not yet a well-designed prospective randomized study comparing letrozole and HRT in PCOS women undergoing frozen embryo transfer.

Microbiome and Polycystic Ovaries

Polycystic Ovary SyndromeMicrobial Colonization

Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder among women in reproductive age with an estimated prevalence of 5% to 19.5%. It is a chronic complex syndrome with psychological (depression and anxiety), reproductive and metabolic abnormalities. The etiology seems to be multifactorial. Lately, interest regarding the association between PCOS women and gut macrobiotic have been emerged. Hyperandrogenism was correlated with those changes in the microbiota which reflects the fact that the microbiome can influence the development and pathology of PCOS . Therefore, aim of this study is to explore the diversity and alternations of the vaginal and the gut microbiome in patients with PCOS during common therapeutic interventions and connect them to different phenotypes of the syndrome.
