How doyou know you're not autoimmune?
How do we know someone is autoimmune?
Many of us with cfs/me are negative to many types of tests like ANA.

Actually high ANA titer does not necessarily means you have an autoimmune illness. One can live with a high titer and never develop one.
ANA was mentioned in one of the abstracts from the IACFSME, on a longitudinal study following adolescent with infectious mononucleosis and ANA was not a predictive factor in developing ME.
I think most of the tests for autoimmunity test for specific antibodies, so if we don't know what the errant antibodies are for a particular autoimmunity, we can't yet test for it. So... I think we could very well be autoimmune, but have no way to test for it. Or we could (mostly) not be autoimmune, but can't be sure because there's no way to test for autoantibodies we don't know exist. Of course, I could have this all wrong. It wouldn't be the first time.What type of labs are used to diagnose autoimmune illnesses. I understand ANA is used as a guide, im guessing theres other tests and criteria's??
Exams and Tests
The health care provider will do a physical exam. Signs depend on the type of disease.
Tests that may be done to diagnose an autoimmune disorder may include:
- Antinuclear antibody tests
- Autoantibody tests
- CBC
- Comprehensive metabolic panel
- C-reactive protein (CRP)
- Erythrocyte sedimentation rate (ESR)
- Urinalysis
No--I think all that you said makes perfect sense to me!!I think most of the tests for autoimmunity test for specific antibodies, so if we don't know what the errant antibodies are for a particular autoimmunity, we can't yet test for it. So... I think we could very well be autoimmune, but have no way to test for it.

I guess im just think they need to research to see if there is a similar mechanisim, i say this because at the moment rituximab and antivirals both work for certain groups of cfs pts to some degree etc. Are we look at the same mechanisms, or similar pathways and can we get sustained and better more effective improvement by combining both therapies.
I just think its worth looking into. If it pans out to be very different then we have two obvious sub groups that can be treated and appropriate testing needs to be worked out to diagnose the right patient for the right treatment. Im not against cfs being an auto immune illness but theres alot of unanswered questions i would like to see answered eventually. I would also like to see ampligen put into this group and work out its mechanisms and if they share any sinilar pathways??
Well I go to the Dr. Klimas group (I assume top of line tests) and they keep testing me and say I am not. I just don't know enough of which tests relate to the autoimunity (I remember one like ANA I think or something like that, keep being negative).How doyou know you're not autoimmune?
Back to the question autoimmunity or not.
Of course we all have our personal theories and stories (and sometimes successes with certain treatments), but anecdotal evidence is only able to give us a hint, nothing more. Sometimes it even fools us. That is why we desperately need as many randomised, placebo-controlled studies as possible, made by the top scientists and doctors.
The only study I know with truly remarkable results is the Retuximab study from Norway. If you read it, you ll see that some patients had incredible improvements and even some went into complete remission. And the disease followed a pattern very similar to other autoimmune diseases. The lagging response (dying Plasma cells and the depletion of antibodies) and the slow return of symptoms, if the treatment stops.
Of course it only worked with 60-70% of the patients. But this is nevertheless a fantastic result! A 100% cure in medicine is very rare. In RA, MS and Lupus, you often have patients, who are resistant to the standard treatment and nobody knows why. So you try other immunosupressive drugs and at the end you are able to help 90%.
The Valgangaciclovir study from Stanford was a bit disappointing. There were some improvements, but it was not overwhelming. I think, Dr. Montoya himself stated somewhere, that he now thinks some antivirals work, because of immune modulation, and not because they kill viruses. And he now uses Colchicine, which is also used in other autoimmune diseases.
The Ampligen study had some mixed results, but some people improved. The mechanism of action is not completely clear. But it certainly has an effect on the immune system.
When I had the course about autoimmune diseases in med school, they told us nearly one hundred times, that we don't know the cause of them. There are some theories, but no certainty.
Wikipedia about MS:
"The cause of MS is unknown; however, it is believed to occur as a result of some combination of environmental factors such as infectious agents and genetics. Theories try to combine the data into likely explanations, but none has proved definitive. (...) Decreased sunlight exposure resulting in decreased vitamin D production has also been put forward as an explanation. (...) Modern genetics have discovered at least twelve other genes outside the HLA locus that modestly increase the probability of MS. (...) Human herpes viruses are a candidate group of viruses. Individuals having never been infected by the Epstein-Barr virus are at a reduced risk of getting MS, whereas those infected as young adults are at a greater risk than those having had it at a younger age."
All this sounds very, very, very familiar.
As others pointed out, if we don't know the autoantibodies, driving our symptoms, we cannot test them. Even MS is mostly diagnosed through symptoms and brain scanning and not blood tests.
I don't want to say, that ME/CFS is definitely an autoimmune disease. But the studies from Norway are a very strong hint into this direction. There are probably some subtypes (as in MS, RA and Lupus as well). I think the cause and the trigger are not the most important to find, but working treatment and further insights into the pathophysiology. If the scientist can point the system, which is broken (certain nerves, the endothelium e.g.), we would have a diagnostic tool and probably a better control of symptoms.
