I hope he and Montoya, or some 3rd party, can see the reasons why.
i am afrraid that the sudy is not a scientific one according to any objective criteria.overall there is no significant difference between the two groups..The base level of the patients was 4 the final level was 6
4
Out of bed sitting, standing, walking 4–6 hours
per day
5
Perform with difficulty sedentary job 40 hours a
week, daily naps
Recovery
6
Daily naps in bed, may maintain a 40-hour
sedentary work week plus light, limited
housekeeping and/or social activities
5 gives a diagnosis of CFS and 6 does not.There is no objective difference between the two.There was no statistical tests actually carried out.you cant perform statistics on subjective parameters.dr Lerner decided that an improvement of 1 on his scale was significant.According to his own data a move from 5 to 6 would be considered significant.I submit that the only difference between 5 and 6 is the wording
There is a lot more to this illness than fatigue.
If his hypothesis was to test that ebv causes CFS then i,m afraid that
i the evidence Normal is an EIPS level above 5
His view is contrary to many published studies who have found that EBV is either not present or not causative
He should have used the null hypothesis as all scientific studies do
If you decide before hand that a change of one ona sunjective scale of 1 to 10 is significant a change of 1 will give an enormously low p value without any significan clinical benefit.
I am only applying scientific criteria for analysing a clinical study.
I would be happy to post the criteria if that would be useful
The lowest scores the patients had was 4 the maximum 6.The differences between 5 and 6 are not clinically significant.In 6 the wording is may hold down a job(a subjective assessment) not can which is an objective one
If you look at the graphs the error bars overlap so the differences as a whole are not statistically significant.They have chosen an arbitary end point when the responses clearly fluctuated over time
People with the kind of infections in Lerners study are ill.An EBV infection does put people in bed.A person with an EBV infection will easily qualify for a diagnosis of CFS under the FUKUDA criteria particularily if the Dr in question believes that EBV causes CFS.Unfortunately it does not mean that they have CFS in any objective sense.People with these infections get better over time without any interventions.This is why a placebo arm is essential .This is the only way of judging the effect of the treatment.Splitting the population into two kinds of CFS based on the type and pattern of infection they were shown to have has no scientific basis what soever.It is based on the assumption that all people with infections have CFS.From that point the study becomes a self fulfilling prophesy.The study fulfills none of the objective requiements ofa scientific clinical study
5 gives a diagnosis of CFS and 6 does not.There is no objective difference between the two.There was no statistical tests actually carried out.you cant perform statistics on subjective parameters.

Everyone with that pathology in terms of viral infection would eventually recover anyway.
Honestly, I think you're missing the forest for the trees
No scientific difference between groups - that's true; there was no statistically scientific difference in the outcomes between Group A and B and that's a good point. I don't think based on this paper, at least as far as I read it, Dr. Lerner can say he has statistical evidence indicating that you must treat other infections as well as herpes infections in order for your treatment of herpes infections to be effective.
Big Difference in Treatment Overall - the main thrust of the paper, however, was not to demonstrate that fact - the main test of the paper was to demonstrate that long-term antiviral treatment in patients with nonpermissive herpesvirus infections is effective and statistically it accomplished that in spades. The p value for the difference between baseline EIPS and Last EPIS was <.00001 - which is n incredible outcome for a treatment trial. I imagine it was so robust as there was so much data in the study - there was no way that that finding was going to be due to chance.
According to Jasons studies the majority of patients diagnosed according to the Fukuda dont have the illness which has PEM as mandatory>Epstein Barr does not cause PEM.EBV does not cause the Neuroendocrine manifestations associated with CCC ME,cfs in the latent phase. There are only two kinds of EBV infection acute and chronic.The same applies for herpes
Again I think you're missing the forest for the trees. Yes, you can argue that one element of the scales could be described differently and decide because of that that the entire scale is no good but on the whole the scale presents a clear trajectory from poor health to better health, and it has been validated in a prior study against standard fatigue scales and it worked as well as they did or better.
Nobody doubts that but the EIPS it's scale isn't a measure of fatigue - its a measure of functionality - which, of course, is CFS patients big goal. This study shows CFS patients going from spending most of their time in bed on average to spending most of their time out of bed and even working. It's much more than a fatigue scale.
Most studies have not looked for nonpermissive infections ie the early antigens to EBV. In fact the few studies that have looked for them - have found them. Check out Lerner's previous studies as well as a Natelson study. Dr. Glaser also believes these kinds of infections play a key role in CFS. I believe he has a small study out.
Yes, if its an the arbitrary choice - but then again, while the EIPS scale may not be perfect -its hardly arbitrary! You're suggesting that there is basically no difference between the points on the scale - I think most people who look at it can quickly see that there is a significant difference between the points on the scale; this isn't rocket science - you go from 0 bedridden to 3 in bed 22-24 hours a day to five in working. I think a lot of people think that the jump from 4 to 5 is way too high; you go from 18-24 hours a day to working a sedentary job with difficulty. But that only buttresses the study's findings because most of the people in the study took that leap - it is that leap which people are looking for. That is the fundamental finding of the study - the average patient went from mostly bedridden to working and with enough energy left over to engage in other activities. Quibbles about the individual scales can't hide that fact.
The decision to call a change of 1 point on the(subjective) EIPS scale significant is entirely arbitary.All learners study shows from a scientific point of view that people with pathogenic infections are ill.They get better.No one knows whether they got better with the drugs or naturally.There is no placebo arm so no conclusion is scientifically possible.There is no statistically significant differences between any of the groups in outcomes. the point is that a value of 5 gives a diagnosis of CFS (entirely arbitary) and six does not.There is no clinical difference between 5 and 6. People with EBV infections are ill they do get better with or without antvirals.The assumption is that these patients had CFS in the first place.It is easy for a patient with EBV to make a fukuda definition of CFS.This is especially true if the doctor making the diagnosis believes the virus is cauative.He has not come anywhere near to demonstrating that that in this study.The study was carried out to test his hypothesis that EBV caused CFS. I really cant see how it could be called a successful study when there is no way of distinguishing cause from effect or any objective method of evaluating treatment efficacy. The EIFS scale has never been independently validated in any way.
all the patients had symptoms of epstein Barr infection.They were given antivirals and they got better.whether they would have got better without treatment no one knows.He is equating having EBV to having CFS.EBV would get nowhere near producing the Cytokine pattern produced in Dr Klimas,s study.
The study I posted above did have a placebo arm, the patients were diagnosed according to the CDC Fukuda criteria and had been sick more than 3 years. EBV is present in 90 percent of the population. I don't understand why you are saying "they only were sick with EBV, not CFS" when there is no such diagnosis as chronic EBV--that's what CFS used to be called.
Well, I'm STILL thrilled.....and I don't give a rats-A@# if the so-called study was done by Mickey Mouse or Donald Duck...I'm just glad that SOMEBODY is attempting to offer treatments (to those willing to try them) AND a bit of HOPE!
Dr. Chia has ALSO been treating hundreds of patients with a variety of anti-virals for some time now...with variable success rates. No STUDIES - no FUNDING - no HELP!
Dr. Chia keeps plodding along, with a one-track mind set and a blind determination - as nobody will pay his work the attention it deserves - presumably because it's not exciting, brand new or groundbreaking data - just the same stuff that's been around for a long time (enteroviruses etc. - difficult to find - difficult to treat) - without getting the focus and the funding it should. (and don't forget Dr. Montoya's work!)
But some of his patients ARE improving - including (even if it's in what some might consider "small" ways AND subjective AND even anecdotal)....me.
I know that Good Science is crucial and must be observed...but I wish we had more people willing to be "Guinea Pigs"...as WAITING for that "good science" to miraculously happen means it may not - in MY lifetime!
None of this really explains to me why common latent infections reactivate in us and not in other people.\
The report is a bit much for my concentration ability this past few days, therefore it's highly likely I'm missing some important facts that would address my questions. I will have to read it again when more clear. But for now, there are a few things that come to mind immediately for me with this study....
First of all this is good news for many pwc's and great news as another contribution to unraveling the puzzle of ME/CFS. It also lends to solidifying the infectious cause position. One concern I have is the difference in responsiveness between groups A & B. The reported high rate of responsiveness is with group A, those with Herpes infections only. The responsiveness is much lower for group B, those with Herpes & co-infections. Well, I have been of the belief that most pwc's DO have Herpes & co-infections, and according to this studies conclusion, would therefore fall into the less likely to respond category. But the study does suggest that those fitting the group A criteria have a really good chance of recovery with this treatment, and that's good news for that group at least.
My own experience as a person with highly reactivated CMV and non herpes co-infections is that treating any of the re-activated infections decreases the symptoms of illness significantly. My experience of treating CMV with Vistide is a great example....The drug is only effective for the CMV and not the co-infections, yet I made dramatic improvements with Tx. Of course relapse is a concern if I don't get the co-infections dealt with and that's been my focus since going off the Vistide in December.
This study at the very least puts many more pieces of the puzzle into place. Soon the xmrv story will add more to the puzzle. I think that Dr Lerner is a man of Integrity and, I feel we are extremely fortunate to have him on our side. I'm thankful for his devotion and years of work on our behalf.
what i am essentially saying is that correlation is not causation.he is labelling a subset with CFS assuming causation when chronic infection with epstein Barr is asymptomatic.If someone has glandular fever then they do have all the symptom of CFS.it does not mean they have the illness.the only way of distinguishing the two is PEM.Most physicians would test for Epstein Barr.if that is positive then that is an exclusion criteria for diagnosing CFS.So by definition active epstein Barr precludes a diagnosis of CFS even under Fukuda. i hope I was clearer that time.sorry for any confusion
This is the relevant part of the FUKUDA paper
Background
The chronic fatigue syndrome is a clinically defined condition (1-4) characterized by severe disabling fatigue and a combination of symptoms that prominently features self-reported impairments in concentration and short-term memory, sleep disturbances, and musculoskeletal pain. Diagnosis of the chronic fatigue syndrome can be made only after alternative medical and psychiatric causes of chronic fatiguing illness have been excluded.
If patients have Epstein Barr virus then they cannot receive a diagnosis of CFS because Epstein Barr is a recognised medical cause of fatigue.Thus a Epstein Barr subset of CFS is impossible.
Gerwyn,
When you say that EBV is exclusionary for CFS, do you mean that basically, if you have EBV you can't have CFS?
I'm totally confused....I thought EBV was very common in CFS patients. Isn't it similar to the other herpesviruses, parvovirus, etc. that tend to show up often in CFS patients?
Also, if you could just clarify how your statement in post #51;
"A person with an EBV infection will easily qualify for a diagnosis of CFS under the FUKUDA criteria"
agrees with your statement in post #62;
"So by definition active epstein Barr precludes a diagnosis of CFS even under Fukuda."
