Filter by: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.
Hirsutism is the presence of terminal hairs in a male-like pattern in females, due to elevated male hormone levels. Females with hirsutism are often overweight and have metabolism disturbances as insulin resistance and impaired glucose tolerance. The previous studies showed that patients with hirsutism (especially them with polycystic ovarian syndrome (PCOS)) have an increased risk to develop type 2 diabetes mellitus on the background of insulin resistance / hyperinsulinemia: 30-35 % of females with PCOS had impaired glucose tolerance and 5-10 % of them diabetes. Hyperinsulinemia increases the risk to develop dyslipidemia and cardiovascular diseases. A previous study in our department who included 340 females with hirsutism (210 with idiopathic hirsutism and 134 with PCOS) showed that 6.6% of them had diabetes and 55% insulin resistance. There were only few long-term follow up studies of patients with hirsutism concerning their risk to develop diabetes. As far as we now, such studies on patients with idiopathic hirsutism are not available until now. Hirsutism is been treated with low dose oral contraceptives, which are suppressing androgen production. This treatment can also influence the risk to develop diabetes and atheromatosis. The previous studies showed that the low dose oral contraceptives had modest influence on the lipid profiles and carbohydrate metabolism in patients with hirsutism, but increased the risk to develop coronary disease. Aim - To study and quantify, in patients with hirsutime, the risk to develop type 2 diabetes on the background of insulin resistance / decreased glucose tolerance and atheromatosis on the background of insulin resistance / hypercholesterolemia. - To clarify the effect of P-pills on patients hair growth and metabolism.
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.
To examine whether serum androgens, measured earlier in life, and variation in genes related to androgen synthesis, metabolism, and signaling are associated with early-onset subclinical coronary atherosclerosis in young adult women from the community.
OBJECTIVES: I. Determine whether reduction of serum insulin levels by metformin increases ovulatory response to clomiphene or spontaneous ovulation in obese women with polycystic ovary syndrome.
To investigate whether women with Polycystic Ovary syndrome (PCOS) have evidence of an increased prevalence rate of subclinical atherosclerosis as measured by the presence of plaque, increased intima-medial carotid artery wall thickness and lower brachial artery flow mediated vasodilation.
OBJECTIVES: I. Determine whether reduction of serum insulin levels by metformin increases ovulatory response to clomiphene citrate in women with polycystic ovary syndrome.
OBJECTIVES: I. Evaluate insulin resistance in thin and obese hyperandrogenic women with polycystic ovarian disease or hyperandrogenism insulin resistance acanthosis nigricans syndrome and in thin and obese controls, using an estimation of tissue sensitivity to insulin. II. Evaluate the effect of androgen suppression with leuprolide acetate and spironolactone on insulin secretion and resistance.
