I understand that ME/CFS has some immune issues as well. In one of the studies I linked, CE/MFS were mentioned to be in the adrenal exhaustion state (low cortisol) as I outlined how that can occur. In that state, the improper functioning of metallothionein from zinc deficiency, there will be an increased sensitivity to heavy metals and vaccines, poor immune function, yeast overgrowth, high susceptibility to parasitic infections/viruses. I can see with TH1 supressed we have a state where viruses will reactivate or take hold that normally would not or parasitic infection as mentioned.

The zinc deficiency causes immunity problems in burnout:

Also in exhaustion, metals accumulate since they arent being detoxed. So its quite possible that mercury can now be present. Mercury happens to inhibit nitric oxide production, which
nitric oxide (NO)
kills or inhibits the replication of a variety of intracellular pathogens should mercury be present when burnout occurs from nutrient deficiency. Mercury, like copper, will further put a demand for magnesium.

Mercury happens to be one of the stressors also as its in nearly all seafood, and dental amalgams. Recent research also mentioned that wifi doubles the rate of mercury release from amalgams. 1.7-3g L-Arginine + 100mg Vitacost Pine Bark Extract or Pycnogenol which converts it to NO I found to work very well with my mercury to restore NO function as long as you supplement. Maybe that would help someone in regard to the virus aspect of the problems, but keep in mind in exhaustion you also still have zinc deficiency,magnesium usually, and likely b vitamins, potassium. Copper is accumulating so you will have issues with that, which also can deplete vitamin c and molybdenum. copper also wont be attached to ceruloplasmin much so its deficient. And low stomach acid will further cause problems with other nutrients absorbing them. So thats probably why these attempts to just fix the virus wont fix you completely. The virus isnt causing all that, its an additional problem. Maybe someone can figure out if there is a way to make copper peptide or such that can act the same as copper attached to ceruloplasmin in the body. Now that would help and be useful during treatment. If copper is ingested and not attached, its not usable and in exhaustion its not going to get bound to ceruloplasmin.
Cortisol can be increased in production by viral infections by the way, so I guess it IS possible that a virus comes first and alongside other stressors mentioned or corticosteroids it starts off the nutrition imbalances of zinc and magnesium leading to the burnout. But the body would in many viruses fight it off unless mercury it appears would prevent NO.
JES, most people remain in a functional state until adrenal burnout. And so long as you have zinc more then copper, and magnesium, you should remain in an earlier state. stress creates an anti stress response of cortisol. The amount of which for those minor stressors is well within the resources of the body to deal with and then things return to normal. Fatigue is mild and usually in the morning when waking up or the mid afternoon in the first stage. To get through the mild fatigue, people turn to stimulants like caffeine. This puts the adrenals into over drive to cover up the early signs and symptoms of the fatigue, but people are completely functional and symptom free. The insulin producing portion of the pancrease is also affected. Imbalance in blood sugar levels results in low energy and this dysfunction is temporarily fixed by quick fixes such as high sugar content soda drinks, energy potions and high carb foods such as donuts, plus caffeine. Many people even consider this state normal as part of living in the modern society. Those who require coffee to kick start a day may already suffer from initial adrenal fatigue and hopefully they are able to keep up those resources of magnesium, zinc, and b vitamins especially to not progress or rest and recovery.
