I have heard of filtration of the blood before, one involved UV exposure of the blood as it was drawn from the body and then recirculated without the virons. The reason for this procedure apparently is to lower the concentration of the virus in the body and thereby promote the achievement of a Rapid Viral Response (RVR) during conventional follow-up with combination treatment with Interferon and Ribavirin. This may be that procedure, I don't know. It involves blood dialysis.

Aethlon Medical Announces Completion Of 30-Day Hepatitis-C Treatment Study Main Category: Liver Disease / Hepatitis Article Date: 22 Feb 2009 - 0:00 PST
Aethlon Medical, Inc. (OTCBB:AEMD) announced that it has completed a 30-day treatment case study to further evaluate the safety and efficacy of the Aethlon Hemopurifier® as a candidate treatment for Hepatitis-C Virus (HCV) infection. The Hemopurifier® is a first-in-class medical device that assists the immune response in combating infectious disease through real-time therapeutic filtration of infectious viruses and immunosuppressive proteins. As in previous studies, which demonstrated robust viral load reductions resulting from three Hemopurifier® treatments administered in a one-week trial, the study enrolled an HCV patient suffering from end-stage renal disease (ESRD) requiring regular kidney dialysis treatment. The study goal was to further demonstrate the Aethlon Hemopurifier® inhibits the progression of HCV in infected ESRD patients. The study protocol provided for 12 Hemopurifier(R) treatments to be administered during the patient's normally scheduled dialysis treatment. As a result, a 4-hour Hemopurifier® treatment was administered thrice weekly over a period of 30 days. There were no observed adverse events were reported in any of the treatments. The study was conducted at the Fortis Hospital in Delhi, India. Aethlon will disclose viral load and associated data upon receipt from testing laboratories. The insight obtained from the study will help define future clinical protocols and early commercialization strategies. The study data may also be utilized to expand the scope of an IDE submission to the FDA to include the potential use of the Hemopurifier® in the United States as a device designed for the single-use removal of HCV from blood. At present, the focus of Aethlon's IDE submission has been directed towards high risk bioterror and emerging pandemic threats.
It is estimated that up to 20% of the 1.6 million global ESRD population is infected with HCV. Beyond the treatment of infected ESRD patients, the overall opportunity for the Hemopurifier® is HCV care is significant, as approximately 180 million people worldwide (3% of the world's population) are HCV infected. According to the World Health Organization (WHO), only 30-50% of infected patients will beneficially respond to the 48-week pegylated interferon-ribavirin treatment standard.
"While we still have much work ahead, I am proud that our research and clinical programs allow us the opportunity to expand the therapeutic filtration industry beyond kidney dialysis and into the much larger infectious disease and cancer markets," stated Aethlon Chairman and CEO, Jim Joyce. "The continued demonstration of Hemopurifier® safety and effectiveness increases the likelihood that our technology will be available to extend and improve the lives of those suffering from these horrific conditions," concluded Joyce.
In a previous studies conducted the Fortis Hospital, six ESRD patients received a series of three, 4-hour Hemopurifier® treatments every other day during the course of one week. The treatment regimen also mirrored the patient's normal kidney dialysis schedule, allowing for the inclusion of the Hemopurifier® without disrupting dialysis treatment. Robust viral load reductions were observed in three HCV patients who completed the three-treatment protocol. Patient #1 had a 95% reduction three days post treatment and 89% reduction seven days post treatment. Patient #2 had a 85% reduction three days post treatment and 50% reduction seven days post treatment, and patient #3 had a 60% reduction three days post treatment and 83% reduction seven days post treatment.
Aethlon additionally disclosed that it soon expects the receipt of viral load and blood chemistry data resulting from a recently completed 30-day HIV treatment case study. The Hemopurifier® is the first medical device to target the treatment of both HIV and HCV, as well as a broad-spectrum of other infectious viral pathogens.
About Aethlon Medical
Aethlon Medical creates diagnostic and therapeutic filtration devices to improve the health of individuals afflicted with infectious disease and cancer. The Company's lead product, the Aethlon Hemopurifier®, is a first-in-class artificial adjunct to the immune system proven to capture infectious viruses and immunosuppressive particles from circulation. The device targets to inhibit disease progression of Hepatitis-C Virus (HCV) and Human Immunodeficiency Virus (HIV), and serves as a broad-spectrum treatment countermeasure against bioterror and emerging pandemic threats. The Hemopurifier® also holds promise in cancer care, as research studies verify the Hemopurifier® effectively captures immunosuppressive exosomes that are secreted by tumors to kill-off immune cells. At present, over sixty-five (65) Hemopurifier® treatments (representing approximately 260 hours of treatment time) have been conducted in multi-site studies at the Apollo Hospital, Fortis Hospital, and Sigma New-Life Hospital in India. The studies enrolled end-stage renal disease (ESRD) patients infected with either HCV or HIV. In addition to establishing treatment safety, robust viral load reductions have been reported in HCV-infected patients who completed a three-treatment protocol during the course of one week.
Research studies have also demonstrated the Hemopurifier® is effective in capturing a broad-spectrum of viruses untreatable with drug therapy, including several of world's deadliest bioterror and pandemic threats. These include: Dengue hemorrhagic fever (DHF), Ebola hemorrhagic fever (EHF), Lassa hemorrhagic fever (LHF), H5N1 avian influenza (Bird Flu), the reconstructed 1918 influenza virus (r1918), West Nile virus (WNV), and Vaccinia and Monkeypox (MPV), which both serve as models for human smallpox infection. The studies were conducted with the assistance of researchers representing: The U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID); The Centers for Disease Control and Prevention (CDC); The National Institute of Virology (NIV); The Battelle Biomedical Research Center (BBRC); and The Southwest Foundation for Biomedical Research (SFBR).

Google "hemopurifier" and you'll get numerous hits leading to essentially the same introductory article, describing what is indeed a "blood filter" cartridge that incorporates plant-derived antibodies designed to target and bind to specific disease-causing agents (such as virions like HCV or HIV) allowing their removal by the filter media.
An example of the article is found here: http://www.popsci.com/scitech/article/2006-03/blood-cleaner
While it is always encouraging to note novel approaches to combating diseases such as HCV, the problem with merely filtering blood is it doesn't address the actual infection sites. Removing free-floating virions is not going to cure anyone, and no such scheme has ever demonstrated improvement in patient condition on its own.
Thus, virtually every "new" treatment approach in recent time has attempted to couple to the "standard of care" as an adjuvant, presuming to raise the success rate of the standard therapy drug regimen. To this point very few have actually proven to be of significant value - indeed, only Telaprevir and Boceprevir have real life data to support the goal of increasing SVR rates.
That said, we can hope this particular "filter" approach shows any such merit in the fullness of time...

Cactus Jammies - 24 Feb 2009 21:26 GMT Grey, Of course you're right about removing virons from the blood not curing hepatitis. But if at the same time, a contraption like this was used to reduce the viral load in the blood supply, one liter of which is present in the liver at any given time, then just perhaps the shotgun approach that tx patients have to undergo could be reduced. One can only hope. How many times did humans attach themselves to wing assemblies before one actually did work and the kook actually flew? I have read of other tests involving reducing the viral load that are underway. Why would a bonafide bioscientist actually undertake such an approach unless statistically there is something to the concept that lowering the VL in a patient's system might possibly have a significant role in the outcome of the tx?
skeptical, too

The realization of flight was not a product of "hope", but simply meeting the challenge of developing the machinations to take advantage of such basic laws.
The concept of reducing viral load via apparatus leading to improved SVR rates is not supported by such basic, immutable laws. There is little data suggesting that lower viral load necessarily implies fewer/lesser manifestations of the disease. That directly affects the viability of using this technology in a fashion similar to dialysis treatment of folks with kidney failure (which, if you recall, was the intended scheme touted by the "UVC Light" people).
And while there is a statistical, inverse correlation between "natural" viral load and SVR rates, it is modest at best, and is most likely due to the underlying effective replication factor - ie, such patients likely have a lower degree of disease. "Simulating" the externally apparent condition by pulling free floating virions out of the blood stream seems unlikely to result in a significant change in outcome, as it doesn't change the underlying state.
Thus, to this point, there is in fact a large "hope" factor involved to this endeavor, and little else.
As to motivation to pursue such efforts, sure, there are humanitarian factors, but as the father of a phd directly involved in novel drug development for the treatment of HIV, I can confidently state that the financial reward for success is the primary mover for the pharma industry and academic research institutes alike. And not without good cause: it's freaky expensive to do the science involved - the numbers my son quotes are staggering, and that's just one - albeit one of the largest - entities in the hunt. "Winning" this battle would not only richen those involved, it would empower a company and/or institution with sufficient finances to take on myriad other challenges. Which can be a good thing.
So...while I am always hopeful that something new will be shown to be effective, I just can't see that this one has legs. If that makes me a skeptic, I say it is with good reason.
Currently, I have invested my "hope" in Telaprevir and Boceprevir, that they will provide a huge improvement in SVR rates, and be true game changers...
