Examining Monocyte Profiles in Critically Ill Patients with Pseudomonas Aeruginosa Sepsis
Official title: Phenotypical Und Functional Characterization of Macrophages in Critically Ill Patients With Pseudomonas Aeruginosa Induced Sepsis
Run by University of Ulm · NCT03044223 · Data updated 2026-11-12
This study is trying to see if the type of immune cells in the blood of critically ill patients with sepsis from Pseudomonas aeruginosa can tell us more about how sick they are and how they might recover.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include critically ill adults over 18 years old with microbiologically confirmed Pseudomonas aeruginosa infections.
✕Probably not a fit
Patients with a life expectancy of less than 24 hours or those participating in other studies may not benefit from this research.

What this trial studies
This observational study investigates the characteristics of blood monocytes in critically ill patients suffering from sepsis caused by Pseudomonas aeruginosa. It aims to determine whether the pro-inflammatory M1 or anti-inflammatory M2 monocyte phenotype predominates in these patients and how this relates to the severity of sepsis and patient outcomes. The study employs flow cytometry to analyze surface marker expression and ELISA to assess cytokine patterns in blood samples. Additionally, an ex-vivo model for Pseudomonas-induced sepsis will be validated to further understand the immune response.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding of immune responses in sepsis, potentially guiding more effective treatments for patients.
How similar studies have gone: Previous studies have indicated the importance of monocyte polarization in sepsis, suggesting that this approach may yield valuable insights, although this specific focus on Pseudomonas aeruginosa is less commonly explored.
