New Device for the Treatment of Bloodstream Infections

I recently came across a press release about a new product to help treat blood stream infections and remove pathogens from our banked blood supply. With the emergence of superbugs and the nasty antibiotic resistant bacteria we face today, I thought this device may be worth investigating.

The medical device company out of Berkley California ExThera Medical has reported success in independent laboratory studies that indicate the blood filtering device Seraph Microbind Affinity Blood Filter can remove a broad range of pathogens and toxins from whole blood.

These laboratory studies indicate the filter is capable of removing:
Drug resistant bacteria: MRSA, CRE (E.Coli and K.Pneumonae), ESBL (KPneumoniae), VRE (E.Faecalis)
Viruses, Fungi, and Toxins: HSV-1, HSV-2; C. albicans; Endotoxin; S. aureus α-hemolysin.
Gram-Positive Bacteria: S. aureus; S. pneumoniae; E. faecilis; E. faecium.
Gram-Negative Bacteria: E.coli; K. pneumoniae; A. baumannii; P. aeruginosa.

This may be good news for patients battling blood stream infections, especially dialysis patients who are at high risk of sepsis and for our blood banking system for the removal of pathogens from stored blood.

The Seraph filter is designed to be used in conjunction with other treatments.  “When the source of a patient’s bacteria is known and has been eliminated, the use of Seraph, optionally combined with antibiotics, may accelerate the clearance of blood-borne pathogens and toxins to a level that can be handled by the patient’s own immune system”.

Bacteria has an affinity to attach to the specially designed adsorption/filtration media and is captured within the disposable device. The filter also contains heparin an anticoagulant. Blood is removed from the patient, passed through the filter to remove infective materials, then returned to the patient.  The filter reportedly has demonstrated the capacity to reduce the concentration of S.aureus and MRSA by 85% with one pass through the filter.

I did note that device was on display at the Critical Care Congress held in San Francisco in January and was introduced to critical care physicians, what puzzled me was the disclaimer that the device does not have FDA approval for distribution in the United States.  After a search of their website, I have yet to find an indication of when FDA approval may be.  It would seem a logical step, as the development of “new” antibiotics will only lead to the development of new resistance.  I happen to like the novel approach to the treatment of blood stream infection and look forward to hearing the news of FDA clearance for this company’s product.
