Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults diagnosed with schizoaffective disorder, bipolar disorder I or II, or related psychotic disorders who are under psychiatric care at Nantes University Hospital.

Probably not a fit

Patients who are pregnant, have a recent history of cancer, or have certain medical conditions such as autoimmune diseases will not benefit from this study.

What this trial studies

This observational study aims to collect biological samples and associated phenotypic data from patients diagnosed with various psychiatric disorders, including schizoaffective disorder and bipolar disorder. The hypothesis is that peripheral inflammatory biomarkers may be common across these conditions, potentially leading to better diagnostic and prognostic tools. Participants will undergo standard blood sampling procedures and interviews with psychiatrists to assess their symptoms using standardized scales. The study builds on previous research and aims to contribute to a larger European research initiative.

Why it matters

Potential benefit: If successful, this study could lead to the identification of biomarkers that improve diagnosis and treatment for patients with psychiatric disorders.

How similar studies have gone: While the approach of using inflammatory biomarkers in psychiatric disorders is being explored, this specific study's methodology is novel and has not been extensively tested in this context.
