Filter by:Polycystic Ovary Syndrome (PCOS) is manifested as a heterogeneous mixture of clinical and bichemical characteristics that complicate study of its etiology. It is currently unclear to what extent PCOS-associated traits (hyperandrogenism, hyperinsulinemia, insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity, and coronary artery disease) are the result of environmental factors or genetic predisposition. We propose to conduct a twin study to investigate the possibility that environmental factors are important in the development of the PCOS phenotype. Twin studies are considered to be the gold standard for determining the extent of heritability of a trait. The proposal described here is only for Step 1 of a larger, multi-step study. The major goal of step 1 is to identify a large cohort of twin pairs, in which at least one member of each pair is likely to have PCOS. Participants for this study will come from the Mid-Atlantic Twin Registry (MATR). Many (3283) potential participants have already been identified based on their answers to a preliminary MATR screening questionnaire. Out of the approximately 7145 twin women of reproductive age who completed these MATR screening questionnaires, 1803 women reported irregular periods, 954 reported ovarian cysts, and 526 reported both irregular periods and ovarian cysts. Many of the women in this last group are likely to have PCOS. They represent 7.4% of the total sample, matching current estimates of PCOS prevalence (4-7%) in reproductive age women. We will also add new twin pairs who meet the criteria (irregular periods and evidence of PCOS or cystic ovaries) as they are recruited into the MATR and take the preliminary surveys. According to MATR statistics, about 33% of twin pairs are monozygotic (MZ, identical). Therefore, approximately 174 of the 526 women likely to have PCOS are members of a MZ pair. Step 1 of the proposed study consists of a telephone survey of the 3282 women with irregular periods and/or ovarian cysts. The survey will be conducted by the MATR. The instrument to be used contains a series of simple and direct questions and will take about 10 minutes to complete. The questions were designed to identify PCOS and their content deals with the frequency of menstrual periods (six or fewer per year being a major diagnostic criterion), a previous diagnosis of PCOS, obesity, excess facial hair and other evidence of hyperandrogenism. The women will also be asked if t...
The purpose of this study is to determine whether oral cinnamon extract are effective in reducing insulin resistance parameters in women with polycystic ovary syndrome.
Oral contraceptives are known to improve menstrual cycles and symptoms in PCOS, however may increase cholesterol. Metformin, a drug to improve insulin resistance, may benefit metabolic state. This study is to determine whether metformin added to oral contraceptive therapy in adolescent women with PCOS improves metabolic state.The study will also test a lifestyle improvement program to reduce weight.
The purpose of this study is to evaluate the effectiveness of the OV-Watch to predict ovulation while women are taking clomiphene citrate.
Laparoscopic ovarian diathermy (LOD) is currently offered to infertile women with polycystic ovarian syndrome (PCOS) who fail to conceive on clomiphene citrate (CC). However, using LOD before CC may result in a better reproductive outcome since LOD may reduce risks associated with CC such as miscarriages and multiple pregnancies. The aim of the study is to evaluate the effectiveness of LOD and its potential value in improving the success rates in infertile women with PCOS. This study will recruit 72 women with PCOS suffering from infertility due to lack of ovulation from the infertility clinic. After initial assessment, patients will be given explanation about the study and will receive an information leaflet. They will then be randomized into two groups: Group1 (36 patients) will receive CC as per infertility clinic protocol to induce ovulation for up to 6 months. Group 2 (36 patients) will undergo laparoscopic ovarian diathermy under general anaesthetic. Blood samples will be taken from both groups before any treatment, shortly after treatment and at 3 and 6 months after treatment to measure various hormones. Patients will be contacted every month after treatment for follow up. The reproductive outcomes particularly the pregnancy and livebirth rates will be compared between the two groups.
To investigate the effect of metformin on pregnancy complications and pregnancy outcome in the II. and III. trimester of pregnancy in women with polycystic ovary syndrome.
The purpose of this study is to determine if the combination therapy of lifestyle intervention and use of Metformin together will improve ovulation induction and hyperandrogenemia in women with polycystic ovary syndrome, by gathering data from adult and adolescent females.
In this study, we will clarify the degree of insulin resistance and characterise muscle glucose metabolism and gene expression in a group of overweight healthy women. The study will clarify how overweight influences body glucose metabolism and thereby in the long-run increases the risk for developing type 2 diabetes. Moreover, the study may clarify why some overweight women develop hormone disorders and diabetes while others remain healthy. The study is essential as many patients suffer from diseases aggravated by overweight. In addition, a genetic disposition for diabetes or polycystic ovary syndrome may give rise to the disease if the patient gains weight. It is therefore important that weight-matched control subjects are included in projects with overweight patients. This clinical trial includes 10 overweight women with regular hormones and normal level of male sex hormone. The patients included must be healthy, take no medications influencing the study results. The subjects must take no contraceptive pills or receive any other hormone treatment. In connection with the investigation, the following will be carried out on all patients: clinical examination, blood tests, hyperinsulinaemic euglycaemic clamp, muscle biopsies, bone scan. The purpose of the study is to gain more knowledge of how overweight influences women's risk of developing hormone diseases and diabetes.
In this study, the investigators wish to investigate how pioglitazone treatment effects hirsute women. Hirsute women are often overweight and have an increased amount of male sex hormone in their blood. Their blood tests show frequent changes corresponding to the changes seen in diabetic patients. Pioglitazone is a drug used for increasing the insulin sensitivity in diabetic patients. Previous studies showed that this drug is able to decrease the level of insulin in blood in hirsute women. Moreover, the level of male sex hormones is reduced during this treatment. The drug has only been marketed for few years, and no investigations have been carried out as to the reaction of other hormones, e.g. growth hormone and stress hormone, using this treatment. This clinical trial includes 30 strongly hirsute women. The patients are randomized to either placebo or an active drug. The treatment period is 16 weeks. The patients included must be healthy and take no medicine possibly changing the results of the study. The patients must take no contraceptive pills or receive any other hormone treatment. In connection with the investigation, the following will be carried out on all patients: glucose tolerance test, clinical examination, blood tests, measurement of stress hormones and sex hormones, hyperinsulinaemic euglycaemic clamp test, muscle biopsies and bone scan. This examination programme will be carried out before start of pioglitazone or placebo treatment and again after 16 weeks of treatment. The examinations require 2½ days of hospitalization. The purpose of the study is to gain more knowledge of the reasons for hirsute women to grow more hair than normal women. The study will show whether pioglitazone treatment can reduce the amount of male sex hormone in blood and how the level of stress hormone and growth hormone is changed when reducing the amount of insulin in blood.
Polycystic Ovary Syndrome (PCOS) is a common endocrine disorder affecting up to 10% of women. The primary symptoms of PCOS are menstrual irregularities, increased body and facial hair, acne, and infertility. This study will test a combination of medications in women with PCOS to determine which works best to overcome infertility.
