Myasthenia Gravis Support Group
Myasthenia gravis (MG) is a neuromuscular disease leading to fluctuating muscle weakness and fatiguability. The hallmark of myasthenia gravis is muscle weakness that increases during periods of activity and improves after periods of rest. Although myasthenia gravis may affect any voluntary muscle, muscles that control eye and eyelid movement, facial expression, and...

OK, I can understand that but, it does beg the obvious question. Does the natural regeneration of those receptors mean that the NMJ has been repaired to the point that it works in just the same way it did before MG came along to attack/destroy it? It is this point and the logical conclusion that results, that therefore all must be well that I question? I'm struggling with the concept that MG is reversible.
My own view of my personal condition is that my genetics are faulty and that my autoimmune diseases are really just a problematic immune system I inherited.
I got MG, like many men, in my older years (65). I had it bad for a time. Prednisone worked as it suppressed my immune system.
The one piece of the puzzle that I am not sure of is immune system connection to hormonal levels. As we all know, most women tend to get this young, often after puberty, and most men tend to get it as we age and our testosterone levels decrease.
In my own case, because I already had osteoporosis before MG, and with prednisone it got worse, I was tested for all of the possible contributors. I was found to have very low teststerone levels due to "primary hypogonadism." As I understand it, in my case my immune system was also destroying my testicles (autoimmune testicular atrophy is an autoimmune disease that attacks the testicles -- this was already happening prior to MG). Anyway, the treatment for that was testosterone replacement (and actually prescribed for osteoporosis as doctors seem to hate to give T prescriptions) and as I began that, I gradually tapered prednisone and was found to be in remission.
Asking my endocrinologist and neurologist is this cause effect, they said "probably not, but who knows." And I continue to take testosterone replacement, thyroid replacement and have been 5 years in MG remission. Is it cause effect? the only way I could know for sure is if MG does come back while I am on T replacement or if I stopped the replacement and waited to see. My doctors insist that is not a good idea, and I am so normal in health now at 71 that I don't want to try either. You can see me today helping my brothers split wood -- I am the biggest one. I added 20 lbs with prednisone and kept it! https://youtu.be/cNcpaMiL69A
Snip - and your blood work turns out saying you have no longer mg that would be a remission
Just noticed this and wonder if this is the case? That the bloods test would or could come back to show no antibodies as being present? I suspect not, but if it were to be the case, perhaps it would prove to be a useful tool to prove the efficacy of the individual treatment? As far as I am aware there is no such test and that is one of the issues we face.
As to remission: I asked my neuro after I was in remission about having the antibody test to see if the antibodies were gone. She said "you will still show up positive even years later, just at a low level" That is why we are never considered cured, just have periods of remission.
Antibodies are a permanent part of our body. Once our body learns how to make a particular antibody, it remembers and continues to keep a few in circulation. They may drop to a level below the test sensitivity, but never disappear completely. If, for some reason, our immune system gets triggered to start producing them in large quantities, then remission goes away as the levels rise and the attack on our muscle receptors begins anew. As our immune system knows how to make the ACHR ones, it can get started rapidly and build up the levels quickly and MG can return abruptly.
Having been in remission for almost 6 years now, I am certainly one of the lucky folks. At age 72, I have some hope that MG will stay away for the rest of my life. However, having been through it from slow diagnosis, to hospitalization, to the 6 months of prednisone to climb out, I know that if it comes back, I expect to get it under control with the same meds as last time -- just will hit them harder earlier.
The only lasting damage I had from MG was not from the disease, but from prednisone and that was cataracts.
Good Luck

Receptors are dynamic proteins in your body they are internalized by your cells when they are old and new ones made. So yes they are regenerated whether you have MG or not. Most of damage in MG comes from complement being deposited at neuromuscular junction not just. Bad antibodies blocking the receptors. Solaris the most recent MG targeted therapy targets complement that’s why it works, doesn’t allow it to get deposited and mess up the junctions. Complement is component of blood.
Thanks for the explanation and indeed the reference to Soliris. The outline on their website of the mechanisms involved at the NMJ are detailed and fairly easily understood.
