Treating a patient with deadly sepsis can be tricky as usually the pathogen is unknown and many patients ultimately die. Researchers at the Wyss Institute at Harvard, using lab animals, have come up with a proprietary protein-capturing agent called FcMBL that binds to not only pathogens but their toxic fragments.
An animal patient, and hopefully some day human patients, has their blood cleansed similar to a dialysis patient by having their infected blood passed through the blood cleansing device. Magnetic beads coated with the FcMBL are introduced to the stream from the patient, bind to the sepsis causing agents, and are effectively removed while the cleansed blood passes back to the patient.
Since sepsis can be caused by many different pathogens like viruses, bacteria, parasites, and fungi this approach is far more beneficial than blindly prescribing antibiotics.
