Official title
Evaluation of the Innate Immune Response Through Monocyte HLA-DR Monitoring During Severe Intra-abdominal Candidiasis in the Critically Ill Patients
Overview
Intra-abdominal candidiasis (IAC) is a frequent and severe fungal infection in critically ill patients, often diagnosed late. Its pathophysiology remains unclear, particularly regarding why some patients develop invasive infection while others only show benign colonization. A potential explanation lies in the state of innate immunity. Monocyte HLA-DR expression, a recognized marker of immune suppression in critical care, may be transiently but profoundly reduced in non-immunocompromised patients who go on to develop IAC. This observational study aims to evaluate whether patients with IAC have greater innate immune dysfunction-assessed by HLA-DR expression-compared to those with severe bacterial intra-abdominal infections. The goal is to better understand the immune mechanisms involved and improve early risk stratification for IAC.
Interventions
- Other Immunomonitoring
To analyse monocyte HLA-DR expression (mHLA-DR) and CD4+ T lymphocyte count (CD4) in both group
Primary outcome measures
- Correlation Between percentage of Monocyte HLA-DR Expression and the Occurrence of Intra-abdominal Candidiasis [Time frame: Within 7 days after abdominal surgery]
Secondary outcome measures (4)
- Change Over Time in Percentage of Monocytes Expressing HLA-DR Measured by Flow Cytometry in Patients With vs Without Intra-abdominal Candidiasis [Time frame: From Day 0 (surgery) to Day 7 post-surgery]
- Variation in Lymphocyte Subpopulations Based on Presence or Absence of Intra-abdominal Candidiasis [Time frame: From Day 0 (surgery) to Day 7 post-surgery]
- Impact of Immune Dysfunction on In-Hospital Mortality [Time frame: From surgery to Day 28]
- Impact of Immune Dysfunction on Source Control of Infection [Time frame: Up to 28 days]
