Strengthening the immune system can make things worse?
 

It seems that most PN is autoimmune, so wouldn't doing things to boost the immune system make things worse? Like taking lots of vitamin C and other supplements. Most of the treatments for PN are immunosuppressants such as corticosteroids. I recently added green tea extract to my daily regimen and my symptoms flared, not sure if it was just a coincidence.

Most PN is not autoimmune. There are MANY different causes of PN and autoimmune does seem to have a good size piece of the pie but it's still far behind conditions like diabetes, B12 deficiency, trauma, alcoholism, medications, etc.

That being said, you are quite correct in saying that boosting your immune system when you have an autoimmune condition can make things worse. AI diseases are, in fact, typically treated with immune suppressors for that very reason. When you boost the immune system, you risk increasing the autoimmune activity.

Vitamin C is a complex and essential nutrient. Humans are the only mammal who cannot synthesize their own Vit C.

So we are dependent on supplements and foods for it.

The best source of information on Vit C is the Linus Pauling Institute ( which is great for all supplements).

Vitamin C is an antioxidant and helpful for inflammation, so with some PNs it is very useful. The severe neuropathy RSD (CRPS) responds to high dose Vit C for example.

Some PNs are caused by toxins, drugs, Diabetes, hypothyroidism, and many other lifestyle issues. Autoimmune factors are more common in women than men, and often are triggered by illnesses, and vaccines. Viruses and bacteria have protein sequences on their cell membranes which may mimic some human tissues. So when you get a Strep throat infection, you may have genetic issues and overproduce antibodies to this strep sequence, and then those excess antibodies may go to the brain and cause a movement disorder called Tourette's (Tics).... the is called PANDAs.
This is PANDAs in more detail:

This type of process is not going to be "caused" by Vit C. It is because people have a set of genes making it more likely. Vit C in fact helps prevent infections, and therefore would prevent some autoimmune reactions that way.

Some doctors believe that full body PN may be a result of a viral infection (or bacterial one), triggering too many auto-antibodies to that organism. This is why we see vaccine reactions... which is an overproduction response to a infectious agent.

If the body produced too many antibodies, wouldn't it kill the virus quicker and thus the PN would eventually resolve?

EXACTLY what MrsD stated!

My comment on 'boosting' the immune system was meant in terms of medications and supplements geared at solely increasing immune function/production...not directed at Vitamin C use, which as MrsD said, is an essential nutrient.

I think you are missing the point. The antibodies LEFT over after the infection, is what is thought to be a form of autoimmune induction. Quickly or slowly getting rid of the virus is immaterial.

You know, some people have a talent for understanding biological systems...it is like a language or like music. If you don't have the education for it or the talent and desire to learn it, you will not quite understand it all. Just like I don't understand football! ;)

Autoimmune disease is pretty complex....
example:

Keep in mind, the immune system is forever cycling, as the antibodies only live for about 21 days. Once that autoimmune cycle begins, it continues. So PN from autoimmune factors don't stop after the trigger (illness, infection, virus, trauma, etc) of the process is gone.

I echo what Mrs. D said. I have some autoimmune conditions already, and a history of bad Lyme Disease (confirmed by blood tests and the whole nine yards as a child).

My doctors believe, although it can't be proven, that my autoimmune diseases are due to my body's immune system going a bit bonkers from the Lyme Disease. I was sick with Lyme for almost a year before diagnosis, and it got all over the place in my body. My immune system was obviously trying hard to kill it off, but was unsuccessful.

The Lyme cleared up with antibiotics-high doses-on and off for 6 months. couple decades later, I got whacked by my first autoimmune disease, which had probably been brewing for some time, and just waiting for the right stressful situation to pounce.

Now, 5 years later, I have idiopathic small fiber neuropathy. ALL my labs are perfect-including the known autoimmune causes. My neuro thinks mine probably is some sort of overly diligent immune system issue I have going on, combined with a less than stellar endocrine and hormonal profile (due to my autoimmune diseases), but that the autoantibodies are simply ones we don't know about yet and have no way to find.

Either way, my options are possibly trials of plaquenil (considering it), extra steroids (already take them in really low doses since my body makes no cortisol), or diet and supps.

For now, it is just diet and supplements. The supplements do seem to help. Maybe in the future I'll consider something else if my symptoms become too much for me to handle on my own.

Also, there's a big difference between taking supplements that are necessary for immune health, and taking ones that are for boosting the immune system. Big difference between "support" and "boost"...although it can get somewhat confusing if you're not reading carefully what nutrients are for what body processes and so forth.

Do you think your SFN is a result from Lyme that is possibly still active? I recently got tested through igenex. Just waiting on results.

With my immunologist hat on, I agree with what mrsD has contributed to this discussion.

One other comment:

This is complicated. Antibodies, which are made by plasma cells (derived from B cells), can bind to viruses, stopping them from infecting cells and helping in their disposal. However, once a cell has become infected with a virus antibodies can not help. Other immune system cells (cytotoxic T cells) then take over - they kill the infected cell, stopping the virus from replicating inside it.
