Sepsis, or blood poisoning, occurs when the body’s response to infection damages its own tissues, leading to organ failure. It is the most common cause of death in people who have been hospitalized, yet no new therapies have been developed in the last 30 years. Many treatments that have prevented death in animal experiments have failed in clinical trials, indicating that a more clinically-relevant sepsis model is needed for therapeutic development.

To bridge this gap, a team of scientists from the Wyss Institute at Harvard University and Boston Children’s Hospital think a better experimental model of sepsis in pigs could help weed out the therapies most likely to succeed in humans. Their method, a scoring criteria to evaluate sepsis in pigs that closely mirrors standard human clinical assessment, is reported in Advances in Critical Care Medicine.
