Blood test may predict best drug for deadly septic shock

This small, completed pilot study aimed to see if two specific substances in the blood (renin and DPP3) could help doctors predict which patients with severe septic shock would have a better blood pressure response to a drug called angiotensin II, compared to standard vasopressor therapy. The study involved 40 critically ill adults and was designed to gather information to plan a larger future trial. The main goal was to learn about these potential biomarkers, not primarily to prove one treatment was better than the other.
