Sepsis study aims to unlock immune secrets for better treatment
NCT ID NCT07273344
First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This study looks at how the immune system reacts during and after sepsis in 400 intensive care patients. Researchers will analyze blood samples to identify different immune response types, called immunotypes. The goal is to understand which immune patterns lead to better or worse outcomes, which could help doctors personalize treatment in the future.
