Filter by:Polycystic ovary syndrome (PCOS) is a common disorder marked by hyperandrogenism, oligo-/anovulation, and subfertility. The precise causes of PCOS are unclear, but the pathophysiology involves complex genetic and environmental influences. Importantly, not all girls with obesity have HA, and free testosterone (T) concentrations are highly variable in this group. Luteinizing hormone (LH) and insulin concentrations are significant but only partial predictors of free T in girls with obesity; significant unexplained variability in free T suggests that additional factors contribute to HA in this population. Abnormalities of ovarian and adrenal steroidogenesis are likely contributors in this regard, but such abnormalities are difficult to quantify. Recent Genome Wide Association Studies have identified DENND1A as a PCOS susceptibility gene candidate. Preliminary in vitro data strongly implicate a DENND1A splice variant called DENND1A Variant 2 (DENND1A.V2) as a contributor to excessive theca cell androgen production in PCOS. The investigators' primary goal with the proposed pilot study is to determine the relationship between urinary exosomal DENND1A.V2 mRNA and free T concentrations in peripubertal girls. The investigators hypothesize that urinary exosomal DENND1A.V2 mRNA quantity is a significant and independent predictor of peripubertal hyperandrogenemia. In this study, the investigators will carefully phenotype peripubertal girls with and without hyperandrogenemia (primarily in the form of hormonal, maturational, and anthropometric measurements) in addition to measuring urinary exosomal DENND1A.V2 mRNA. As a primary analysis, the investigators will examine the relationship between morning free testosterone and urinary exosomal DENND1A.V2, controlling for previously-described partial predictors of free testosterone (LH, insulin) in addition to potential confounders (BMI z-score, bone age). These studies will provide important information regarding the etiology of HA in peripubertal girls. Ultimately, these data may lead to a non-invasive test of ovarian/adrenal steroidogenic activity and support the development of a diagnostic test for PCOS in high-risk peripubertal girls (e.g., those with obesity).
The present study is a randomized pilot study, overweight/obese adolescent and young PCOS subjects will be assigned into two groups: Taichi arm and control arm. Hormonal profile and metabolic profile will be determined.
This is a Phase IV, prospective, observational, single arm, multicenter trial to identify the population at high risk of overstimulation associated with signs and symptoms of PCOS and examines the utility of 12.5 international units (IU) increment of Gonal-f® new pen for individualized controlled ovarian stimulation (iCOS).
PCO patients will be assessed clinically,urine & blood samples will be tested. Systolic & diastolic blood pressure, serum glucose & insulin levels, lipid profile, C-reactive protein, complete hormonal profile, and Urinary albumin excretion will be measured.
Forty eight PCOS patients were included . The diagnosis of PCOS was made based on the three criteria set by the Rotterdam Consensus meeting definition of PCOS (ESHRE, ASRM, 2004). The criteria were as follows: 1. history of chronic anovulation defined as cycle length > 35 days, or less than 9 cycles per year or amenorrhoea (cycle length > 12wks), 2. infertility with hirsutism or acne or elevation of one or more of serum androgen levels 3. ultrasonographic findings of polycystic ovaries ( increased ovarian volume, more than eight follicles in an ovary ranging from 2-10mm). the studied subjects were to receive metformin 850 mg twice daily over a period of 6 months. Blood samples were collected at the start of the study, before receiving metformin, where baseline serum insulin (fasting and 2 hr postprandial), sex hormone binding globulin (SHBG) , total and free testosterone, Dihydroepiandrostenedione sulphate (DHEAS) and Antimullerian Hormone (AMH) were obtained before starting metformin. Blood samples were collected at 3 and 6 months respectively of metformin treatment , to asses its effect on serum levels of the previously mentioned hormonal parameters.
Polycystic ovary syndrome (PCOS) is the most common Female endocrine disorder , with a prevalence ranging between 6% to10% based on the National Institutes of Health (NIH) criteria and when the broader Rotterdam criteria are applied it reaches as high as 15%. Typically, PCOS can identify during the early adolescence. Insulin resistance is a common finding in the obese women with PCOS. It is most prevalent and severe in PCOS phenotype involving hyperandrogenism and chronic anovulation. Women with PCOS who have regular cycles are metabolically less abnormal. Acanthosis nigricans (AN) is a dermatosis characterized by velvety, papillomatous, brownish-black, hyperkeratotic plaques, typically of the intertriginous surfaces and neck. Although AN is associated with malignancy, the recognition of its more common connection to obesity and insulin resistance allows for diagnosis of related disorders including type 2 diabetes, the metabolic syndrome, and polycystic ovary syndrome. Significant improvements in ovulation and pregnancy rates as a result of clomiphene treatment after metformin in women with clomiphene-resistant PCOS were reported in a popular randomized, double-blind, placebo-controlled trial . The first pharmacological approach to induction of ovulation in women with PCOS is clomiphene citrate
110 infertile women diagnosed as polycystic ovary syndrome (PCOS) at the age group of 20-35 distributed randomly : - 55 women will receive letrozole 2.5mg twice daily orally from the 2nd day to the 6thday of the cycle for three successive cycles. - 55 women will receive clomiphene citrate 50 mg twice daily orally from the 2nd day to the 6thday of the cycle for three successive cycles. Patients will be subjected to: Complete history taking: 1. Details about name, age 2. Menstrual history with determination of menarche 3. Amenorrhea or oligomenorrhea , Regularity of the cycle 4. History of endocrine disease. 5. History of previous operations. - Physical examination: - General examination: With special concern to: --Acne. --Hirsutism . --Weight. --Height --BMI was determined : Wt. in kg ـــــــــــــــــــ = ) Height in m)2 - Abdominal examination : - for scar of previous pelvic or abdominal operations . - Pelvic examination : - vaginal examination for enlarged cystic ovaries. - ultrasound for diagnosis of pcos. PARAMETERS: (1) rate of ovulation (primary parameter). (2) serum progesterone level on day 21. (3) number of mature follicles produced per cycle. (4) mean endometrial thickness. (6) chemical pregnancy. (7) ongoing pregnancy
Polycystic ovary syndrome (PCOS) is the most common cause of anovulatory infertility which affects 12-21% of the population.Several studies performed evaluate the possible benefit of metformin alone or in combination with clomiphene (CC)as first-line treatment for infertility in women with PCOS have reported conflicting results. These conflicting results may be due to the presence or absence of insulin resistance(IR).Metformin decreases IR .However there is not a single randomized clinical trial with metformin in IR PCOS patients. Therefore, the aim of current study is to compare CC with coadministration of metformin and with CC with coadministration of placebo in IR PCOS patients to induce ovulation.
Polycystic ovary syndrome (PCOS) is the most prevalent endocrine disorder in reproductive age women. PCOS is usually characterized by an excessive androgen production, menstrual irregularities, and polycystic ovaries. Women with PCOS are often obese and have a varying degree of insulin resistance (IR). Weight reduction constitutes the initial treatment for these patients. Metformin has proven to be useful in IR and is frequently used in PCOS. However metformin use may be accompanied by gastrointestinal discomfort, and a high abandon rate. Other therapeutic alternatives such as magnesium and polyunsaturated fatty acids have been used in other IR states and may be useful in PCOS. The aim of this study is to asses the efficacy of these alternatives in obese PCOS patients.
This is a double blind randomised placebo-controlled study involving women with polycystic ovary syndrome (PCOS). The patients will be randomised either to Vitamin D 3200 IU or placebo for three months. The main hypothesis of this study is "Vitamin D improves hormonal, metabolic and cardiovascular risk markers in women with PCOS".
