Again:This particular study doesn't state whether these patients fulfill either of the definitional criteria. They're just categorized by presence or lack of energy, which isn't even enough to tell if they meet Fukuda...the patient population being treated should be defined.
I agree with you on this part:"International criteria for diagnosis of CFS were used.2" (footnote 2 is the Fukuda criteria).
Perhaps the most problematic part of the paper is the first sentence of the abstract: "We hypothesized that chronic fatigue syndrome may be caused by single or multiple Epstein-Barr virus (EBV), cytomegalovirus (CMV), or human herpesvirus 6 (HHV6)." ... They may just be opportunistic, as is seen with infections like toxoplasmosis in AIDS.
Again:"International criteria for diagnosis of CFS were used.2" (footnote 2 is the Fukuda criteria).
But then Dr. Lerner states, "The Group A herpesvirus CFS patients (no coinfections) returned to a near-normal to normal life (P = 0.0001). Group B CFS patients (herpesvirus plus coinfections) continued to have CFS."
This suggests that the patients in Group A did not have CFS. This is inaccurate on two counts. They did not go back to normal (increasing to only an average of 6) even on the energy index, and no other components of their illness were measured at all.
Perhaps the most problematic part of the paper is the first sentence of the abstract: "We hypothesized that chronic fatigue syndrome may be caused by single or multiple Epstein-Barr virus (EBV), cytomegalovirus (CMV), or human herpesvirus 6 (HHV6)."
This implies that a positive finding to the research will demonstrate that those viruses indeed are a/the cause of the disease. Just because symptoms improve as a result of treating these viruses doesn't mean that they're causal factors though. They may just be opportunistic, as is seen with infections like toxoplasmosis in AIDS.
How does it suggest that? They met the strictest criteria in existence for CFS.
Technically that might be true, but in practice it appears mostly to be a moot point. If the patients resumed a normal life after treatment, then the treatment addressed enough of the cause of the symptoms to be essentially a functional cure. I doubt many people who had such a benefit were upset because the "real cause" of the disease wasn't fixed. And for all anyone really knows, it was. At least in those patients who responded.
Maybe I'm being too demanding, but I think the whole concept of a "functional cure" is setting our sights too low.
It's such a complex disease, maybe it's just a bit beyond out reach at the moment to figure the whole thing out. With an all or nothing approach you could well end up with nothing.
They met the Fukuda criteria (which is not as strict as the Canadian Criteria). But only improvements in fatigue (rather than in the other symptoms) as a result of the drugs were measured in the study.
Lerner study said:Cardiac muscle disease, syncope, chest pain, positive tilt table tests, tachycardias at rest, decreased left ventricular ejection fraction, and left ventricular dilatation improved and/or disappeared with antiviral treatment. The abnormal HM is a reliable biomarker of CFS cardiac disease.
I think improvements are great, but they aren't the same thing as the resolution of the illness.
Maybe I'm being too demanding, but I think the whole concept of a "functional cure" is setting our sights too low.
I'm truly happy that these doctors are finding ways to give people improvements. But until they can get people not just "Functionally Cured" but actually "Truly Well," they should keep looking for additional ways in which patients can be helped further.
Regarding your subsequent post, do you honestly believe no doctors have ever looked at the possible role of mold in this disease?
Yes, I am absolutely sure that none of the "name" CFS doctors have put any substantive effort into considering the role of toxic mold in this illness.
The only exceptions are Judy Mikovits (as a result of discussions with Erik Johnson), Rich van Konynenberg (as a result of discussions with me), and Ritchie Shoemaker.
I welcome evidence to the contrary.
Best, Lisa
Thanks for bringing up Nancy Klimas. That's a very good catch.
Here's a quote from her (January 11, 2008, ProHealth Q&A):
Q: Any thoughts as to the role of environmental toxins like mold?
Dr. Klimas: Anything that over-stimulates the immune system is suspect, and some molds also give off immunosuppressant factors. Another potential subgroup of CFS... I have seen sick building syndrome cases that are almost certainly working through this mechanism.
In bringing up the "immunosuppressant factors," Dr. Klimas is actually coming closer to implicating mold as an underlying cause than I was.
I never said the word "cause" (much less "primary cause") in this thread. I just said that researchers would do well to consider the idea that heavy mold exposures might be undoing the positive effects that their treatments otherwise could be having, if they want their studies to have positive outcomes.
Since Dr. Klimas believes that one subgroup of CFS patients has symptoms that are "working through the mechanism" of Sick Building Syndrome, it makes sense that she would ask all patients to actively look into whether they have hidden toxic mold problems in their homes, and to address those problems (through remediation or moving) if they find those problems.
Does anyone know if she does that?
Thanks, Lisa
Look - in general I don't disagree with you, and I also agree with that Klimas quote. But first, we're talking about a sub-group here, second mold doesn't appear to be causative, and third, Sick Building Syndrome is not the same thing as Chronic Fatigue Syndrome. There might be some symptom overlap, but afaik they are distinct entities.
I don't mean this in a "thread police" way, but this is a thread on the Lerner study and the results he found with antivirals. So I don't think diverting it to a discussion of mold is really appropriate. I'm sure we all wish there were researchers looking at every possible aspect of CFS under the sun, but unfortunately that isn't happening, and that is also not the focus of this study.
This study is also not so much a research study as it is a clinical study. That's how I view it, at least. Yes, there are some flaws in it. But I think in some respect we have to take it on its face - by which I don't mean not to criticize the methodology, etc. - but not fault it for what it's not and what it's not trying to be. I think his results are interesting, they might not represent a "cure," but only a functional improvement, or however you want to categorize it, but it's one more part of the picture that at least someone is reporting on. If XMRV pans out, who knows how something like this might dovetail with XMRV to actually provide the "cure" we all want. don't throw out the baby with the bathwater, especially just because it's not the gender baby you wanted.
Anncavan...ONE questions as I dont remember reading about the dosages in the paper (i know they were using valacyclovir and what else? ..but were the dosages stable? were they titrated up through the years? any idea?) thanks! j
He reported that Vistide (brand name)/Cidofiovir (generic) - was effective against HCMV but that he uses it only for the patients who have not responded to the standard protocol after at least 1 year because it can affect the kidneys.
Is standard protocol using the Valtrex? Is this effective for HHV-6 and HHV-5 as well as EBV. The article isnt quite clear?
Do you know Cort, what he means by Standard Protocol?
Thanks
Thanks for the link to the complete paper. Lerner tested his patients for viruses, then used antivirals to treat them, while monitoring all patients very closely -- every 4 weeks. The effectiveness of the treatment varied, depending how many viruses were found in the patient.
Now we learn the success of the treatment, which is great. The only part that made me gasp was the comment this costs $1,000 per month! Yikes.
Oh, I want to get better! Even if 4 years sick, for me, was a year in the last century. Stop getting worse, that would be great.
Lerner has had more success than Montoya. I hope he and Montoya, or some 3rd party, can see the reasons why. Montoya had spectacular success in his first small group of patients, a paper that grabbed much interest, and I thought, got him resources for a slightly larger study. Is there a very basic logic here, treat virus infected patients with anti viral drugs? Carefully, as the drugs are potent.
I love the good news to know these people have better lives, more function in their day. Thank you!
