Congenital Adrenal Hyperplasia Clinical Trials

At baseline, subjects will be admitted overnight for a 24-hour endocrine profile whilst on their standard therapy. Subjects will attend the study site in the morning and have 17-hydroxyprogesterone (17-OHP) and androstenedione (A4) levels assessed at 15:00, 17:00, 19:00, 21:00, 23:00, 01:00, 03:00, 05:00, 07:00, 09:00, 11:00, 13:00 and 15:00. ...

Congenital adrenal hyperplasia (CAH) results from a deficiency of a key enzyme in the biosynthesis of cortisol, mainly 21-hydroxylase, resulting in its classic form a neonatal salt loss syndrome and / or a virilization syndrome in girls. The treatment of the disorder in adulthood involves administering steroidal compounds with the ...

Because of the excess of androgen caused by 21-OHD CAH, women with CAH may exhibit some male-like characteristics. Glucocorticoids are a member of a class of drugs called corticosteroids, which are used in hormone replacement therapy. In order to counteract the effects of 21-OHD CAH, women with the disease are ...

The conventional glucocorticoid replacement therapy in primary adrenal insufficiency (Addison's disease) and congenital adrenal hyperplasia renders the cortisol levels unphysiological, which may cause symptoms and long-term complications. This therapeutical approach does not enable to restore physiological circadian and ultradian rhythm of glucocorticoids. Current studies conclude that constant or unphysiological administration ...

17α-hydroxylase is a rare form of congenital adrenal hyperplasia. Patients with complete 17α-hydroxylase deficiency may come to attention to the doctor at their early adulthood due to hypertension or disordered puberty. 17α-hydroxylase is a form of cytochrome P450 enzyme in the adrenal cortex for the production of cortisol, while 17,20-lyase ...

Congenital adrenal hyperplasia (CAH) is an inherited inability to synthesize cortisol in the adrenal gland. More than 90% of cases are cause by deficiency of steroid 21-hydroxylase (CYP21, also termed CYP21A2, P450c21), which is a cytochrome P450 enzyme located in the endoplasmic reticulum. It catalyzes conversion of 17-hydroxyprogesterone (17-OHP) to ...

CAH patients are treated with glucocorticoids and mineralocorticoids. Ideally, the glucocorticoid doses should be sufficient to suppress the elevated ACTH secretion, and hence attenuate the increase in androgen levels. Because of this, CAH patients use higher steroid doses than patients with autoimmune adrenal insufficiency (Addison's disease) and therefore are in ...

Congenital Adrenal Hyperplasia (CAH) is a genetic rare disease, which alters the adrenal production of gluco and mineralo corticods. The treatment consists in supplementing children with hydrocortisone. Despite care for these children has improved substantially across decades, short adult height (AH) still remains an important consequence of the disease. About ...

CAH is a genetic steroidogenesis disorder. The most common form, 21OHD, leads to cortisol deficiency and, in turn, an excess of androgen, a hormone that promotes the development and maintenance of male sex characteristics. As a result of this androgen excess, prepubescent males and newborn, prepubescent, and grown females exhibit ...

All subjects will have a screening visit prior to the baseline assessment to allow DIUR-006 procedures to be fully explained and informed consent to be given by the subject. For subjects from DIUR-003 this screening visit will include safety blood tests. Any subjects not meeting the inclusion/exclusion criteria following these ...
