Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 day to 15 days
  • All sexes
  • No healthy volunteers
  • Child

Study population: Newborns (boys and girls) diagnosed with a neonatal form of CAH and followed up in one of the following 5 French reference centres: Robert Debré Hospital, Paris; Necker Hospital, Paris; Bicêtre Hospital, Le Kremlin-Bicêtre; Trousseau Hospital, Paris; Femme-Mère-Enfant Hospital, Lyon.

Who may be able to join

  • Newborns with confirmation or strong suspicion of diagnosis of congenital adrenal hyperplasia:
  • Newborns with abnormal differentiation of the external genitalia, without palpable gonad at birth and high 17 OHP plasma level
  • Newborns diagnosed with antenatal CAH,
  • Newborns diagnosed at birth with CAH (due to parents at risk of transmission of the disease),
  • Newborns diagnosed by systematic screening for 17 OHP on the 3rd day of life (thus having a high dosage of 17 OHP), confirmed by a second sample.
  • For all these patients the diagnosis of CAH will have to be confirmed secondarily by molecular biology.

Who cannot join

  • Newborn with an anomaly of sexual differentiation from another origin,
  • Newborn already under treatment with Fludrocortisone and/or Hydrocortisone.

About this study

Congenital adrenal hyperplasia (CAH) in its classic neonatal form with severe salt-wasting represents a challenge for pediatric endocrinologists in order to maintain sodium balance, especially as the physiopathology and optimal therapeutic management of this urinary salt loss remain poorly studied, particularly during the neonatal period.

The human kidney presents the characteristic of being immature at birth with a functional tubulopathy associating sodium wasting and difficulty to concentrate urine, in connection with a transient renal resistance to aldosterone action, which is exacerbated in case of CAH by insufficiency of aldosterone production.

The objective of project is therefore to study the secretion profiles of plasma and urinary steroids in neonates with classical salt-wasting form of CAH before treatment and under treatment with Fludrocortisone and Hydrocortisone during the first months of life, using an advanced technology: LC-MSMS (Liquid chromatography coupled with tandem mass spectrometry). The study of the existence of a correlation between plasma and urinary steroid profiles will also make it possible to subsequently consider simplified medical follow-up for these patients.

This project will lead to a better understanding of sodium handling and steroid secretion and excretion profiles in CAH neonates, in order to improve the therapeutic management of mineralocorticoid replacement in these patients.

Read the detailed description

Congenital adrenal hyperplasia in its severe salt-wasting form is a challenge in order to maintain sodium balance. The pathophysiology of this impaired sodium balance is still poorly investigated as well as its therapeutic management, notably in the neonatal period. Consensus practice guidelines have been established for hydrocortisone replacement therapy, in order to maintain negative feedback on the pituitary-adrenal axis to prevent from virilization and excessive growth velocity. However, mineralocorticoid substitution and sodium supplementation is currently empirically adapted based on weight gain and renin levels. There is significant need for improvement of this essential part of CAH treatment. Particularly, CAH patients have higher risk of adverse cardio-vascular outcomes, which could relate to an excessive glucocorticoid and/or mineralocorticoid exposure in early infancy rather than to the genotype of the patient.

A clinical human study in classical CAH neonates, using Liquid Chromatography coupled to tandem Mass Spectrometry LC-MS/MS technology will assess prospectively plasma and urinary steroid profiling (precursors and substitute hormones, notably Fludrocortisone dosages) during the first six months of life, before and under treatment; and in correlation with genotype.

Thirty neonates (boys and girls) diagnosed with a severe form of CAH and followed in one of the 5 following French reference tertiary centers: Robert Debré Hospital, Paris; Necker Hospital, Paris; Bicetre Hospital, Le Kremlin-Bicetre; Trousseau Hospital, Paris; Lyon Hospital, , will be included in the study and will be followed for a period of six months. The duration of inclusion will be 24 months.

Genotyping will be processed for all children in Lyon.This project will lead to a better understanding of sodium handling and steroid secretion and excretion profiles in CAH neonates, in order to improve management of mineralocorticoid replacement.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plasma LC-MSMS dosages

    Determine if a correlation exist between plasma and urinary steroid profile by LC-MSMS and genotype before treatment, and if there exist a correlation to the Fludrocortisone dose after 48h of treatment

    Measured: 48 hours

  2. Urinary LC-MSMS dosages

    Determine if a correlation exist between plasma and urinary steroid profile by LC-MSMS and genotype before treatment, and if there exist a correlation to the Fludrocortisone dose after 48h of treatment

    Measured: 48 hours

Secondary outcomes (2)
  1. Plasma LC-MSMS dosages

    Steroid profiles will be compared between urine and plasma to search for a correlation

    Measured: day1, day2, 1 month, 3 months and 6 months

  2. Urinary LC-MSMS dosages

    Steroid profiles will be compared between urine and plasma to search for a correlation

    Measured: day1, day2, 1 month, 3 months and 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Congenital Adrenal Hyperplasia (CAH), run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 16 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma LC-MSMS dosages (time frame: 48 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Sep 2022.
