About this study

Official title: Investigation of Urinary Steroid Metabolites in Children With Autism Spectrum Disorder

Deviation of hormone formation within nerve cells and nerve system provides autism spectrum disorder and neurodevelopment retardation through interaction of steroids with neurotransmitter-receptors, calcium-channel receptors and genomic interaction via nuclear steroid receptors.

Urinary steroid metabolites will be compared between children with autism spectrum disorder and healthy controls.

Read the detailed description

Autism spectrum disorder presents many alterations in amino acid metabolism and in neurotransmitter systems (gamma amino acid system, glutamate-glutamine, nicotine-acid, serotonin-system) . Also alteration in gene activation within nerve cells and lymphocyte cultures encloses over 600 genes, affecting a wide field of enzymes , metabolic pathways and hormone formation. Male hormones and their precursors are often increased and their influence to nerve cell growth and spine formation is evident.

The diagnosis of autism spectrum disorder is made in accordance of criteria of the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) of the American Psychiatric Association by an experienced and specialised paediatrician or psychologist and /or by an Autism Diagnostic Interview-Revised (ADI-R) or Autism Diagnostic Observation Schedule (ADOS) .

Overnight urine with measurement of quantity and time will be collected and a little part of the urinary samples will be frozen for storage till analysis. Age, weight and length of the children at collection time will be ascertained.

Four stratified groups (autistic boys, girls, and healthy controls, boys and girls, each age 5-15) will be formed.

Urinary samples will further remain anonymous through an Identification-Number (ID).

Analysis of hormones and the most of the known metabolites excreted in urine will be performed by a specialised laboratory using gas chromatography-mass spectrometry (GC/MS) analysis (University Hospital Bern, Steroid Laboratory, Switzerland).

The statistical analysis, with age, gender, weight, diagnosis and hormone analysis results as factors , consists in linear regression analysis to detect deviation in hormone formation and metabolism.

What is being measured

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

  1. difference in hormone formation and androgen precursors

    Calculation of hormone formation by comparison of urinary steroid metabolites

    Measured: 3 years

Secondary outcomes (1)
  1. difference in hormone formation in gender and age

    Hormone formation depends on age and gender and will be calculated by comparison of urinary steroid metabolites

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Autism and Autism Spectrum Disorder, run by Intersci Research Association, Austria at 1 site in Austria.

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 2 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 19 Feb 2019. 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 Austria. 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?

Results are not available in the source record.

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?

difference in hormone formation and androgen precursors (time frame: 3 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01197131, which also lists 4 linked publications.

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 19 Feb 2019.
