Examining the link between blood markers and pulmonary embolism in ARDS patients

Official title: Association Between the Level of Extracellular Vesicle - Associated Tissue Factor and the Occurence of Pulmonary Embolism in Patients With Acute Respiratory Distress Syndrome

Run by Assistance Publique Hopitaux De Marseille · NCT05855317 · Data updated 2026-11-12

This study is testing if certain blood markers can help understand the risk of pulmonary embolism in patients with Acute Respiratory Distress Syndrome (ARDS) in the ICU.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older who are admitted to intensive care with ARDS as defined by specific clinical criteria.

Probably not a fit

Patients with a positive SARS-CoV-2 PCR prior to ICU admission or those with coagulation disorders will not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study will include 120 patients diagnosed with Acute Respiratory Distress Syndrome (ARDS) in an intensive care unit over a two-year period. Participants will undergo a blood test to measure coagulation biomarkers, including EV-TF, upon inclusion. Following standard treatment protocols, patients who receive an injected CT scan between Days 5 and 28 will be categorized based on the presence or absence of pulmonary embolism. The study aims to compare EV-TF levels and other biomarkers between these groups to identify any potential associations with pulmonary embolism.

Why it matters

Potential benefit: If successful, this study could enhance the understanding of biomarkers in predicting pulmonary embolism in ARDS patients, potentially leading to improved patient management.

How similar studies have gone: While the specific association of EV-TF with pulmonary embolism in ARDS is novel, similar studies have explored biomarkers in critical care settings with varying degrees of success.
