Sepsis is a bloodstream infection caused by an uncontrolled spread of pathogens and release of toxins that can lead to systemic inflammation and multi-organ failure. Sepsis is the leading cause of hospital deaths and kills at least eight million people worldwide each year. Current treatment is to administer patients broad-spectrum antibiotics because there is often not enough time to identify the specific cause of infection. Diagnosis takes two to five days and every hour one waits can increase the risk of death by 5-9%. In this episode of Disruptive, Wyss Institute Founding Director Don Ingber and Senior Staff Scientist Mike Super discuss how their team developed a new therapeutic device inspired by the human spleen. This blood-cleansing approach can remove sepsis-causing pathogens from circulating blood without ever needing to know their identity. In animal studies, treatment with this device reduced the number of targeted pathogens and toxins circulating in the bloodstream by more than 99%. This device may radically transform the way sepsis is treated.
