Active clinical trials for "Polycystic Ovary Syndrome"

Polycystic ovary syndrome is a frequent cause of abnormal menses and infertility. It has also been related to cardiovascular disease. The objective of this trial is to evaluate the clinical and metabolic efficacy of metformin plus life style modifications in women with polycystic ovary syndrome compared with life style modifications and placebo

Increased insulin levels leads to increased secretion of D-chiro inositol(DCI) from the kidneys in women with PCOS, but not in normal women. This leads to a reduction in circulating DCI and insulin stimulated release of DCI-IPG.To determine if decreasing circulating insulin directly by inhibition of islet insulin release with diazoxide in obese women with PCOS 1)decreases the renal clearance of DCI and 2) increases the circulating concentration of DCI.

The goal of this three-armed randomized controlled trial is to establish the relative roles of treatment of hyperandrogenism versus obesity (as the largest modifiable factor contributing to insulin resistance) in treating infertility and improving pregnancy outcomes among obese PCOS women. The investigators hypothesize that the key to restoring ovulation leading to live birth is to correct hyperandrogenism with oral contraceptive pills, but the key to avoiding later pregnancy complications is to improve insulin sensitivity with weight loss.

There have been some controversies regarding the use of preparations with LH activity in patients with polycystic ovary syndrome (PCOS) who have high endogenous LH activity. In this research we aimed to compare urinary menotrophin versus recombinant FSH (rFSH) with respect to the prevention of OHSS

The primary objective is to determine if meals of different fat and fiber content affect postprandial plasma testosterone concentration in women with polycystic ovary syndrome. Our hypothesis is that a high-fiber meal will have a greater reduction in testosterone composition compared with a high-fat meal.

This is a placebo controlled trial investigating the effect of 6 months atorvastatin 20mg/day therapy on androgens, glucose metabolism and inflammatory markers in women with PCOS. We assume that during 6 months atorvastatin therapy a significant improvement in hyperandrogenism, glucose metabolism and inflammatory markers is observed.

The purpose of this study is to compare and determine the efficacy of letrozole administration to that of laparoscopic ovarian diathermy (LOD) in infertile women with Polycystic ovary syndrome(PCOS)not responding to treatment with Clomiphene alone.

Insulin-resistance plays an important role in polycystic ovary syndrome (PCOS) physiopathology. The phosphoprotein enriched in the diabetes (PED/PEA-15), a 15 kDa protein related to insulin sensitivity, is over-expressed in type 2 diabetic patients and in PCOS women, independently of obesity. The effectiveness of oral contraceptives pills (OCP) or metformin (MET) in PCOS management is still uncertain. Aim of this pilot clinical study was to compare the effects of OCPs or MET on the expression of PED/PEA-15 in association with insulin sensitivity in obese PCOS women. Outcome measures: PED/PEA-15, BMI, plasma glucose and insulin, 1/HOMA-IR, homeostasis model assessment of insulin resistance; QUICKI, quantitative insulin sensitivity check index; ISI: whole-body insulin sensitivity index. Study design: twenty obese PCOS women (age: 24.7±18 yr; BMI: 30±2.4 kg/m2) were randomized according to insulin sensitivity to receive 30 µg ethinylestradiol plus 30 mg drospirenone 21 day/month or MET 1250 mg three times daily for 6 months. Results: At baseline, age and BMI were not different in the two groups; PED/PEA-15 protein expression was higher in MET than in OCP group (p=0.011), along with higher 1/HOMA-IR (p=0.004), and lower QUICKI and ISI (p=0.003 and p<0.001, respectively). After treatment, independently of body weight, only in MET group PED/PEA-15 decreased (p=0.004), along with insulin and 1/HOMA-IR (p<0.001), and QUICKI and ISI increased (p<0.001). Insulin sensitivity indexes improvement correlated significantly with PED/PEA-15 protein expression, but not with BMI. Conclusions: PED/PEA-15 protein over-expression in obese PCOS women with IR reduced after a six month treatment with MET, while remained unchanged in the OCP group. The reduction was independent of body weight, and correlated with insulin sensitivity indexes. This effect further supported MET as a more effective therapy than OCPs for obese PCOS women with IR, also when fertility is not required.

The objective of this study is to assess the effects of a high protein (HP) and a normal protein diet (NP) on patients with polycystic ovary syndrome (PCOS) and body mass index (BMI)-matched controls in a sample of southern Brazilian women. Patients will be randomized to receive high protein (30% protein, 40% carbohydrate, 30% lipid) or normal protein (15% protein, 55% carbohydrate, 30% lipid) during eight weeks. The investigators hypothesis is that a different diet composition may have influences in changes of the main characteristics of PCOS, like hyperandrogenism and metabolic syndrome.

Current research has shown that the use of diabetes management practices aimed at reducing insulin resistance and hyperinsulinemia (such as weight reduction and the administration of oral antidiabetic drugs) in women with PCOS can not only improve glucose and lipid metabolism but can also reverse testosterone abnormalities and restore menstrual cycles. A new medicine called exenatide (Byetta) has been found to reduce body weight, as well as, improve abnormal glucose metabolism in diabetics. This randomized study will compare Exenatide (Byetta) to extended release metformin (Fortamet) to combination therapy (both Byetta and Fortamet) on menstrual cyclicity, hormone profiles and metabolic profiles over a 24-week period in women with PCOS.
