Overview

Chronic Toxoplasma gondii (T. gondii) infection is a widespread condition that can negatively affect brain function and is considered a risk factor for various psychiatric conditions, including depression and schizophrenia. This prospective observational study aims to investigate the expression levels of specific circulating microRNAs (miRNAs) in women diagnosed with schizophrenia, major depressive disorder, or bipolar disorder who also have chronic toxoplasmosis. By comparing these levels to patients without the infection, the study seeks to determine if these miRNAs can serve as biological markers to help differentiate between specific psychological disorders and identify the impact of chronic toxoplasmosis on mental health.

Eligibility

Inclusion Criteria:

  • Confirmed psychiatric diagnosis of Schizophrenia (SCZ), Major Depressive Disorder (MDD), or Bipolar Disorder (BD) according to DSM-5 criteria.
  • Seronegative for T. gondii IgM (to ensure infection is not in the acute phase).
  • Signed informed consent.

Exclusion Criteria:

  • Psychiatric disorders other than Schizophrenia, MDD, and Bipolar Disorder.

Seropositive for T. gondii IgM (indicating acute infection).

Refusal to participate.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
