Expecting one intervention to help one at a time isnt too useful as there is a cascade of other things that happens in this illness. Working this as a systems biology problem is more helpful. For instance, EBV can deplete nutrients like zinc and vitamin C, deplete collagen and increase symptoms from the nerves between discs in the spine, stress the adrenals and thyroid causing adrenal insufficiency and low T3 syndrome, fragment mitochondria, cause oxidative and nitrosative stress, put a load on the immune system causing other viruses to reactivate and weakened immune function, and trigger all kinds of autoimmunity, none of which are fixed by the list of drugs you tried.
In addition to your ME/CFS specialist, you might try working with a functional medicine doctor who might help you with some of these issues.
And, my ME/CFS specialist had me on Valcyte for 20 months, not 3.
There are many things missing from this list which is a random smattering of different treatments which will only work if you have a problem that they will help. Properly testing to figure out what problems you have and applying treatments appropriately is far more successful.
For example, B12 does not work by itself, it works in concert with other B vitamins and mineral cofactors.
Candida and oxalates are gut problems that are not on this list and treating them can make a big difference.
Treating ammonia can help with brain fog.
Glutathione and branched chain amino acids can help with PEM.
Martin Pall's peroxynitrite reducing protocol and Thomas Seyfried's mito correction protocol can be helpful.
IVIG has supported my immune system to be able to help fight viruses and bacteria. It has done nothing for my pain because I don't have pain.
Rituximab, when appropriately prescribed has helped some of us, as has plasmapharesis - both are for autoimmunity.
And so on.
The test results you showed were just antibodies. Once you've had these illnesses, your antibody titers will probably be high and chasing them while on medications is not terribly productive. Why is your doctor not testing quantitative PCR for these infections?
