PyroEVs/PLIN3 Mediate Lipid Droplet-Mitochondrial Coupling in Sepsis Endothelial Injury

Objective: To investigate the correlation of PyroEVs and PLIN3 with the severity and prognosis of sepsis patients.

Participants: Sepsis patients meeting the Sepsis 3.0 diagnostic criteria admitted to the Intensive Care Unit of Zhongda Hospital affiliated with Southeast University, as well as healthy volunteers.

Inclusion Criteria:

1. Presence of confirmed or suspected infection; 2. Sequential Organ Failure Assessment (SOFA) score increase ≥ 2 points from baseline; 3. Signed informed consent. Exclusion Criteria: Age < 18 or > 80 years, pregnancy, cancer patients, and individuals with diseases potentially complicated by vascular endothelial cell injury.

Primary outcome: 28-day mortality, SOFA score

Primary outcomes

  1. Concentration of pyroptic extracellular vesicles (PyroEVs) in plasma

    Time frame: Day 1

    The concentration of pyroptic extracellular vesicles (PyroEVs) in plasma will be measured using nanoparticle tracking analysis. Results will be reported as particles per milliliter (particles/mL).

  2. Concentration of PLIN3 in plasma

    Time frame: Day 1

  3. 28-day mortality

    Time frame: 28 days

  4. SOFA score

    Time frame: 28 days
