Filter by:Background: - Congenital adrenal hyperplasia (CAH) is a genetic disorder of the adrenal gland. The adrenal gland is located in the abdomen and produces small amounts of hormones such as cortisol, aldosterone, and androgen. These hormones help control blood pressure, protect the body, and maintain good health, especially during development. People with CAH do not make enough cortisol and aldosterone, and make too much androgen. This can lead to serious medical problems. The standard treatment is to take pills that mimic the effects of cortisol and aldosterone. However, treatment with pills can have long-term side effects because of the higher doses needed, and may not work well for some people. - A possible new treatment for CAH is to use a pump to deliver cortisol under the skin. Similar pumps are often used to give insulin to people with diabetes. Researchers think that a cortisol pump might be able to help the body use the cortisol more effectively than taking pills. They want to compare the results of a cortisol pump and standard pill treatments for CAH. Objectives: - To compare the effectiveness of a cortisol pump with standard cortisol pill therapy for CAH. Eligibility: - Men and women at least 18 years of age who have CAH (see more details in Eligibility section below). Design: - This study will involve four inpatient hospital stays at the National Institutes of Health in Bethesda, MD over 6 months (spaced 2 months apart). The first and last stays will last about 5 days. The second and third stays will last about 3 days. - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - At the first study visit, participants will provide regular blood and urine samples. They will also have imaging studies. These studies will look at the bones, fat, and muscles in the abdomen and pelvis. - Participants will receive a cortisol pump during the first visit. They will be shown how to use the pump. They will also learn what to do, if they need to take extra "stress dose" cortisol pills. - At the second and third visits, the cortisol dose given with the pump will be adjusted as needed. Blood and urine samples will also be collected. No imaging studies are scheduled for these visits. - The last study visit will have the same tests as the first visit. Participants will be offered the chance to continue with the pump treatment for 1 more year, or go back to their standard pill treatment.

Treatment with glucocorticoids and mineralocorticoids has changed congenital adrenal hyperplasia (CAH) from a fatal to a chronic lifelong disease. Long-term treatment, in particular the chronic (over-)treatment with glucocorticoids, may have an adverse effect on the cardiovascular risk profile in adult CAH patients. The objective of this study was to evaluate the cardiovascular risk profile of adult CAH patients.
The purpose of this study is to gather safety and effectiveness information about a new formulation of Hydrocortisone (Chronocort®) used to treat patients with a disease called congenital adrenal hyperplasia (CAH). Hydrocortisone is the man-made version of the hormone cortisol, which is released in the body following a regular daily pattern. The objective of the study is to measure the levels of hydrocortisone that are absorbed into the bloodstream once Chronocort® is taken and what affects it has on other hormones in the body. Since Chronocort® is anticipated to mimic the same release pattern of cortisol in the body, it is hoped that patients with CAH will be treated more effectively to manage their disease.
High lipid peroxidation and altered antioxidant defenses have been frequently reported in Alzheimer's disease patients. The purpose of this study is to investigate susceptibility to photo-oxidation of isolated erythrocyte membranes, in patients affected by Alzheimer's disease and age- and sex-matched, non demented subjects.
Background: - Polycystic ovarian syndrome (PCOS) is a group of disorders related to problems with the secretion of certain hormones, which can lead to reproductive and other issues in women. Frequent complications of PCOS include irregular menstruation, development of ovarian cysts, and insulin resistance. The adrenal glands, which sit on top of the kidney, are involved in the production of certain hormones and the regulation of steroid levels in the blood, and may be affected in women with PCOS. Researchers are interested in studying possible connections between the adrenal glands and PCOS in young women who have been diagnosed with PCOS and healthy volunteers with normal menstrual function. Objectives: - To investigate possible connections between adrenal gland steroid hormone secretion and polycystic ovarian syndrome. Eligibility: - Women between 16 and 29 years of age who have been diagnosed with PCOS, or who are healthy volunteers with normal menstrual function. - Participants must be willing to discontinue the use of oral contraceptives or any other medications that alter steroid hormone production for at least 1 month before the start of the study. Design: - Participants will be screened with a physical examination, medical history, and blood and urine tests. All participants will also have a pelvic (ovarian) ultrasound. - All participants will be admitted to the hospital for a 1-week testing period, which will involve the following tests: - Regular blood draws for two 2-hour periods (late evening and early morning) to measure hormone levels - Fasting blood draws with a dose of corticotropin to test the body's adrenal function - Hormone level measurement following regular doses of dexamethasone (a drug that controls the function of the adrenal gland) - Daily urine collection for 6 days. - Other studies, such as imaging studies of the adrenal glands, may be conducted as required by the study researchers.
The goal of this study is to help investigators to understand more about the development of characteristics related to being male or female (what is called gender development). The investigators will study girls with congenital adrenal hyperplasia (CAH) aged 10 to 13 to learn more about the girls' interests and activities, thoughts and feeling about being female, and family relationships. This will help investigators to understand the ways in which gender development is shaped by hormones and family relationships.
Congenital Adrenal Hyperplasia (CAH) is one of the commonest inherited diseases, affecting 1:14,200 live births. It is the result of a genetic defect in one of the enzymes (in most cases 21-hydroxylase) required for cortisol biosynthesis, leading to reduced levels of cortisol and aldosterone, increased ACTH concentrations and consequently increased adrenal androgen production. Patients suffer from problems with growth and development and as adults patients may have problems with fertility, virilisation in women, testicular masses in men and both men and women have an impaired quality of life. Patients have to take life-long therapy. Despite its frequency knowledge surrounding the management of adults with CAH remains fairly limited. There has been a lot of work describing the management of children with CAH but to date there is no consensus on how to manage adults. To address this issue a number of adult endocrinologists in the UK under the auspices of the Society for Endocrinology have established a country wide study (CaHASE) to undertake research in order to set standards of care for adult patients with CAH. In CAH the severity of the symptoms experienced by affected individuals varies depending on the mutation and the genetic background of the individual. The ability to tailor CAH therapy on an individual basis, as determined by the severity of the underlying defect and an understanding of the likely natural history of the disease, is a key goal in clinical management. Correlation of phenotype (clinical status) and genotype (the underlying 21 hydroxylase gene mutation) will facilitate stratification of severity and provide an important contribution to the debate on potential mechanisms of individualised therapy. For instance it may become clear that certain CAH genotypes are associated with specific long term outcomes. In time, this could lead to suggesting different treatment strategies in certain groups. Moreover, genotype data are important if we are to address the relative contribution of environment (e.g. treatment) vs. genetics on long term outcomes. This multi-centre study aims to: 1. - Investigate the medical health of adults with congenital adrenal hyperplasia. 2. - Investigate the relationship between the genotype of the patient and the phenotype. 3. - Investigate the quality of life of adults with congenital adrenal hyperplasia.
The purpose of this study is to determine if dexamethasone given at night is a more effective treatment for congenital adrenal hyperplasia in young children than standard three times per day hydrocortisone. Our hypothesis is that nocturnal dexamethasone will lead to more efficient suppression of the hypothalamic-pituitary-adrenal axis. We performed a cross-over trial comparing hormonal control during two 24-hour hospitalizations, one on hydrocortisone and one on nocturnal dexamethasone.
This qualitative interview-based study will investigate the impact that living with congenital adrenal hyperplasia has for women in the following areas: health-related quality of life (HRQL), psychological health, and health-seeking behaviors.
The purpose of this study is to develop a more physiological approach to the management of children and adolescents with salt wasting Congenital Adrenal Hyperplasia. We will administer the glucocorticosteroid via insulin infusion pump to see whether this treatment will improve the serum hormone concentrations.
