About this study

Official title: Childhood Trauma in Schizophrenia: Exploration of Links Between Gene Expression, Cerebral Morphology and Symptomatology. SCHIZO' TRAUMA

Childhood trauma is known as a vulnerability factor in schizophrenia. In healthy volunteers, these adversities are linked to a decrease of grey matter of the brain, similar to those observed in schizophrenia.

In a previous study based on Voxel-Based Morphometry (VBM), including 21 schizophrenic patients and 30 healthy volunteers, the investigators shown a negative correlation between emotional neglect (important dimension in childhood trauma) and grey matter decrease. This strong correlation was significantly higher in schizophrenic patients than in healthy volunteers, suggesting a higher genetic predisposition to environmental factors in schizophrenic people.

Currently, interaction between genetic predisposition and environmental stress factors is the major model for understanding in schizophrenia. In order to analyze both effects on human body, particularly on brain, several studies currently focus on the product of genetic expression, the ribonucleic acid (ARN).

The purpose of this study is to provide an explanatory model of links between childhood trauma, candidate gene for schizophrenia expression, cerebral morphology and schizophrenic symptomatology. Using conceptual framework of stress vulnerability, structural equation modeling (SEM) will allow testing causal link between these different variables.

Questions about this trial

What is this clinical trial studying?

An observational study of Schizophrenia, run by Centre Hospitalier Universitaire de Saint Etienne 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 23 inclusion and 18 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 17 Jan 2024. 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?

Childhood Trauma Questionnaire (CTQ) for childhood trauma. (time frame: 5 days). The study lists 4 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 17 Jan 2024.
