NCT ID: NCT03760835 Recruiting - Clinical trials for Congenital Adrenal Hyperplasia

Congenital Adrenal Hyperplasia Once Daily Hydrocortisone Treatment

CareOnTIME
Start date: August 11, 2016
Phase: Phase 4
Study type: Interventional

This is a controlled, open study designed to compare the effects of dual-release hydrocortisone preparations versus conventional glucocorticoid therapy on clinical, anthropometric parameters, metabolic syndrome, hormonal profile, bone status, quality of life, reproductive, sexual and psychological functions and treatment compliance in patients affected by congenital adrenal hyperplasia due to 21 OH deficiency.

NCT ID: NCT02795871 Recruiting - Clinical trials for Congenital Adrenal Hyperplasia

Prenatal Dex Study

Prenatal Dex
Start date: October 2016
Phase: N/A
Study type: Interventional

The classic form of 21-hydroxylase deficiency (prevalence 1/15,000) is the most common cause of congenital adrenal hyperplasia (CAH). This autosomic recessive disease is responsible for virilization of the external genitalia in girls through androgen hypersecretion during fetal life. Since 1984, the Lyon Pediatric Endocrinology group has proposed prenatal dexamethasone (DEX) for all fetuses at risk of CAH With the aim of preventing fetal androgen hypersecretion in affected girls and avoiding poor long-term results from reconstructive surgery. Prenatal DEX was used in Europe and the USA but its use was recently suspended: in 2007, a Swedish study conducted on 26 children treated with DEX in utero for a short period of time reported cognitive impairments. These data were not confirmed by an American study on the short-term DEX use, which showed potential cognitive impairments in CAH children exposed to DEX for long periods of time. These confusing and controversial results have caused the scientific community to question its position and have resulted in the suspension of the use of prenatal DEX with drastic consequences for CAH girls (virilization; genital surgery etc.). In this context, an evaluation of neuropsychological development under in utero DEX is essential to validate its indication for use during the prenatal period. This study will evaluate outcomes using prospective cognitive and emotional assessments. It will first focus on the unaffected children previously treated in utero in order to assess the adverse effects of the drug. The study will then assess the children with CAH for whom DEX could have beneficial effects.

NCT ID: NCT02552251 Recruiting - Clinical trials for Congenital Adrenal Hyperplasia

COrticosteroid in Congenital Adrenal Hyperplasia

COCA
Start date: August 2012
Phase: Phase 2/Phase 3
Study type: Interventional

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 aim to substitute the gluco- and mineralocorticoid deficit on the one hand, and effectively curb the adrenal hyperplasia and adrenal androgen pathway in girls . The terms of glucocorticoid treatment are not clearly codified and are based on several steroidal compounds and various protocols. The advantages in terms of adrenal suppression and disadvantages - including bone and metabolic - different treatments have not been clearly established in the literature. The main objective of this study is to compare among adults with HCS in its classical form the impact on hormonal parameters adrenal suppression glucocorticoid of 3 types of treatment administered to equivalent dose and according to the usual procedures. The secondary objective is to compare in the same patients the impact of different drugs and treatments on several metabolic bone parameters. The study will include 40 adult patients bearing a HCS in its classical form and will include 3 treatment sequences of eight weeks each, during which they will be administered sequentially in random order at random and according to the known equivalences hydrocortisone, prednisone (CORTANCYL) and dexamethasone (DECTANCYL). Randomization will be stratified based on previous DMARDs in the investigation that may be different for different patients, knowing that France hydrocortisone and dexamethasone are used mainly for the treatment of congenital adrenal hyperplasia. The judging criteria will be: i) the criteria of adrenal hormone suppression: plasma levels of testosterone, androstenedione, 17 OHP, ACTH and diurnal variations of the 17 OH progesterone salivary ii) the criteria of the metabolic impact of glucocorticoids: plasma glucose levels , blood lipids, and insulin sensitivity index HOMA-R calculated from glucose and insulin, iii) the criteria of bone impact of glucocorticoids: plasma for CTX bone resorption and bone alkaline phosphatase P1NP for bone formation iv) the living quality criteria evaluated by the PGWB Questionnaire (Psychological General Well-Being). The duration of the study period will be 24 months.

Continuous Subcutaneous Hydrocortisone Infusion in Congenital Adrenal Hyperplasia

CAH
Start date: February 2013
Phase: Phase 2
Study type: Interventional

The conventional glucocorticoid replacement therapy in congenital adrenal hyperplasia (CAH) renders the cortisol levels unphysiological, which may cause symptoms and long-term complications. Glucocorticoid replacement is technically feasible by continuous subcutaneous hydrocortisone infusion (CSHI), and can mimic the normal diurnal cortisol rhythm. This method was recently applied to treat a patient through a critical phase of puberty. This is a clinical trial aiming to evaluate CSHI treatment in patients with CAH. The main objective is to determine the effects of CSHI on metabolic parameters (androstenedione and 17-hydroxyprogesterone profiles, and testosterone,adrenocorticotropic hormone(ACTH), cortisol, and bone markers), and to determine the required glucocorticoid doses. Secondary objectives are to determine effects on clinical status, body weight, blood pressure and other metabolic parameters, as well as on subjective health status (AddiQoL, SF36).

NCT ID: NCT00694525 Recruiting - Clinical trials for Adrenal Hyperplasia, Congenital

Role of the Protein Osteoprotegerin in the Bone Health of Women With Congenital Adrenal Hyperplasia

Start date: April 2008
Phase: N/A
Study type: Observational

21-hydroxylase deficiency (21-OHD) is an inherited disorder that results from a mutation on the CYP21A2 gene. It affects the adrenal glands and is the most common cause of congenital adrenal hyperplasia (CAH). 21-OHD CAH causes the body to produce an insufficient amount of cortisol and an excess of androgen, the type of hormone that produces male characteristics. The primary treatment for 21-OHD CAH, glucocorticoid replacement therapy, has been shown to cause bone loss. However, the elevated hormone levels caused by 21-OHD CAH may increase production of the protein osteoprotegerin (OPG), which in turn may protect against bone loss. This study will compare bone density and OPG levels in women who have 21-OHD CAH and have undergone a lifetime of glucocorticoid replacement therapy to that in women who have neither of these criteria. In doing so, the study will aim to determine the relationship between OPG and bone loss.

Determining the Long-Term Effects of Prenatal Dexamethasone Treatment in Children With 21-Hydroxylase Deficiency and Their Mothers

Start date: January 2008
Phase: N/A
Study type: Observational

Congenital adrenal hyperplasia (CAH) is a genetic disorder that affects the amount of steroids that the body forms. The most common form of CAH is 21-hydroxylase deficiency (21OHD), which leads to cortisol deficiency and causes the development of mature masculine characteristics in newborn, prepubescent, and grown females, and prepubescent males. Prenatal treatment with dexamethasone, a corticosteroid, has been shown to reduce the masculinization of genitalia. However, the long-term effects of dexamethasone on the children who received it as fetuses and on mothers who were exposed to it while they were pregnant have not been determined. This study will investigate potential long-term adverse side effects of prenatal dexamethasone treatment in children and young adults who received dexamethasone as fetuses and their mothers who were exposed to it during pregnancy.
