New study aims to spot deadly transfusion complication earlier
NCT ID NCT06444750
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks for proteins in the blood that could signal transfusion-related acute lung injury (TRALI), a rare but dangerous complication in ICU patients. Researchers will compare blood samples from 210 people, including ICU patients with and without lung injury, and healthy volunteers. The goal is to find biomarkers that help diagnose TRALI faster and improve transfusion safety.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a blood test that helps doctors quickly diagnose TRALI in critically ill patients, potentially saving lives.
- What could go wrong
- This is an early observational study, not a treatment trial. It may not find clear biomarkers, and any findings will need much more testing before they help patients.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
Samples from twenty TRALI patients are already available at Sanquin Blood Bank. These samples have been collected within 24 hours after TRALI onset. The only clinical data available for these samples is sex and age. This is our study group. As control we will include ICU patients in University Medical Center (UMC): * Patients without lung injury receiving a blood transfusion; * Patients with indirect ARDS receiving a blood transfusion; * Patients with pneumonia receiving a blood transfusion; * Patients with indirect ARDS, who do not receive a blood transfusion; * Patients with pneumonia who do not receive a blood transfusion; * Healthy volunteers recruited through Sanquin's donor system

Inclusion criteria Patients on the ICU: 1. Without lung injury who received a red blood cell (RBC) or platelet transfusion (PLT). 2. With indirect ARDS with and without a blood transfusion (RBC or PLT); 3. With pneumonia, with and without a blood transfusion (RBC or PLT). Exclusion criteria 1. "Objection to registration of data for scientific use" as noted in the patient file. 2. Patients in whom it is impossible to obtain blood samples. 3. Patients with massive hemorrhage. 4. Patients with ARDS due to multiple transfusions.
