Understanding the role of the body's biological clock in sepsis

Functionality of Endogenous Biological Clock in Sepsis

Observational University of Athens · NCT04063332

This study looks at how sepsis affects the body's natural clock and immune system to see if understanding this can help improve treatment for patients with sepsis.

What this trial studies

This observational study aims to investigate how sepsis disrupts the immune system's circadian rhythms and the central circadian clock. By comparing septic patients to healthy controls and patients without sepsis, the study seeks to identify the extent of this dysregulation and its impact on patient outcomes. The research will analyze the expression of genes related to circadian rhythms and their influence on immune function during sepsis. The findings could provide insights into potential therapeutic approaches to improve sepsis management.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older, either healthy controls, patients without sepsis, or patients diagnosed with sepsis.

Not a fit: Patients with certain conditions such as solid tumors, neurodegenerative diseases, or those on corticosteroids may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies for sepsis by addressing circadian rhythm disruptions.

How similar studies have performed: While the specific approach of this study may be novel, previous research has indicated the importance of circadian rhythms in immune function, suggesting potential for success.
