Severe infections, including sepsis, can affect how the immune system works and may lead to poor recovery or death. Researchers want to better understand these immune changes so that people at higher risk can be identified earlier.\n\nThe main questions this study aims to answer are:\n\nAre certain immune cell patterns linked to survival or death within 28 days? Are these immune patterns linked to organ failure or longer stays in the ICU? Participants will be adults with severe infection who are admitted to the ICU as part of their routine medical care. This study does not change or add to their medical treatment.\n\nParticipants will:\n\nHave small blood samples collected at several time points during their ICU stay Allow researchers to review their medical records, including test results and outcomes Researchers will analyze immune cells in the blood and relate these findings to clinical outcomes. The results may help improve future risk assessment and understanding of immune changes in people with severe infection.",[35],"Sepsis",[37,35],"immune cells","NOT_YET_RECRUITING","2025-12-31",{"date":41,"type":42},"2026-01-12","ACTUAL",{"date":44,"type":31},"2026-01-15",{"date":46,"type":31},"2028-01-15",{"name":5,"class":6}]
