Sepsis claims the lives of 8m people worldwide each year but in in many cases blood cultures never make a positive identification, so the problem is often treated blindly. But, notes a [s]The Conversation[/s] report, there is some hope. [b]Harvard’s Wyss Institute[/b], in collaboration with other Harvard colleagues and two hospitals, have developed a dialysis-like therapeutic device that could radically transform the way doctors treat sepsis. The ‘biospleen’ is a device which filters pathogens and toxin from flowing blood without requiring doctors to identify the pathogen causing the problem – and it captures antibiotic-resistant bacteria as well. The device was able to remove more than 90% of bacteria from the blood of rats in a few hours. It also increased survival when these animals were injected with a lethal bacterial toxin.
