Thanks George, Karen and Otis.
the IRIS problem that will have to be addressed as well in order for a treatment program to work.
Total sense Otis. Yeah, that's the impression I get from what I saw and read afterward. But hey it's a bit over my head as well. (grins) I got the impression that there are antibodies to XMRV but like the virus itself they are low count and this is why there is a problem in finding them every time. I know from my own experience that my EBV reactivation titers are consistently between 3800 and 5700 (over 150 is positive, grins) when I have an EBV flare but there is a big fat 9 (well below the 150 threshold) for the actual "capsid" antibody.
In other words my body is not responding to actual EBV although there is some present because you carry silenced EBV with you for life. Rather the "flare" is caused by proteins put out by the "recombined" XMRV/EBV/MLV combo. It lease that's how the SFFV MLV mouse model works. So there are antibody's to XMRV and to which ever "primary" and later "secondary" infections you have had.
This is not going to be an easy ride.
So to extend this to realistic treatment it seems (worst case anyway) we will need highly individualized testing to nail down the target viruses so they can put together a tailored anti-viral combo which will may need to deal with multiple virus families (retro, herpes, etc.). Well, I guess this may (eventually) be a good career move for infectious disease docs who want to roll up their sleeves and get into a new world which, right now anyway, is looking really complicated.
Looks like we need lots more research money than I had envisioned.

Hi George, do you think that IRIS is the cause of the problems that many of us are having with LDN?

Otis said:So to be sure I got the hypothesis. You have a high "EBV viral load" as detected by the EBV tiers, but they're not specific to distinguish "pure EBV" from the XMRV/EBV/MLV combo platter of proteins. On the flip side your immune response, as measured by the antibody test, is very low because apparently the immune is much more "specific" in it's response and doesn't recognize the XMRV/EBV/MLV protiens as a threat (that it recognizes).
Did I get that right?
No wonder we're so dang sick. Our immune system (even with the simplifying assumption it's not messed up by the viruses) is tuned to respond with antibodies to VERY specific virus signatures (much better than the tests for the viruses) and meanwhile we're getting slammed by these virus combinations (to which we can't mount a meaningful immune response) in ways no one can really understand right now.
Wow.
So then, if we tamp down enough of the viruses via meds our immune system can mount a meaningful response against what's left because it can "see " what to attack again.

A quick addition to Karen's notes on Dr. Bateman's presentation:
Cohorts, cohorts, cohorts!
Dr. Racaniello talked about HTLV. I believe he said that it was like XMRV with very few copies in the blood, difficult to detect, and that it spreads in the body similar to XMRV (not positive about the spreading but it sounded similar). He then went on to say that there are no anti-retrovirals that work against HTLV. The anti-retrovirals that work against HIV work because it is reproducing like mad.
In my mind I had it all worked out in a very simple manner. I would be tested and find I have XMRV. I would take ARVs (maybe current ones or maybe ones that will be developed later). I would then be better.
Now i am not so sure.

... Most of use will have really high titers in the Antigen and nuclear antigen, protiens made by active EBV but if the virus itself shows up as a goose egg, (it becomes invisible because it stuck like a limpet to the XMRV) then your doctor is not going to treat you with antivirals. Not unless your vet. . . I mean doc is way smarter than mine. (grins)
So yeah, when the dust settels I think doctors will have to run a complete panel of possible pathogens on Long Term Patients to find out how many each person has and provide at least some basic antiviral treatment . For newbies or those under say 5 years they will probably just provide Ampligen to up the NK function and some anti-retroviral meds to stop the XMRV from attaching other viruses and hiding them.
Course the entire line of inquirey could end up to be a dead end. But my money's on Sandra Ruscetti being right.
Is a recording available online?
The DHHS has a really brilliant strategy, I think, they withhold all of the publications for as long as they can and there are dozens of them. That buys them as much time as they can milk. Unfortunately the CFS patient group is pretty unforgiving on the time issue. (grins) THEN they let all the papers publish one right after another, an avalanche as it were. This actually buys them more time because the patients, patient advocacy groups, media and general public will have to wade through the subsequent mess! By the time the dust settles figure three to six months they are set up to deal with the problems.
It usually takes a few days. jspotila usually posts a new thread when it's available. I just watched the last one. It was maddening because the slides and audio were out of sync.
Prof. Racaniello then presented the history of AIDS and HTLV as examples of the amount of time needed from discovery to treatment:
...
HTLV-1 was discovered in 1970 as the cause of ATL, Human T Cell Lymphoma. In 1986, it was also associated to another disease, myelopathy. Since then, blood has been screened for HTLV.
