Hello All,

I could really use some help in deciding what to do and would welcome any thoughts, suggestions or experience in general or with the drugs my neurologist wants me to begin taking or similar diagnoses. The neurologist states that Aetna, will at some point, want to discontinue me using IVIg. At this particular time I am doing better, but may be still progressing. I am likely in one of my relapse/remit phases. I can not tell if it is my lower back causing some of the issues in my right foot or disease progression. Back to the story, the neurologist wants to start me on Imuran or Cellcept. He was skeptical of whether my disease is caused by an autoimmune issue, he is not the neurologist that gave me my diagnosis, maybe that is why he has been skeptical in the past, but now agrees that what I have appears to be autoimmune in nature. Not sure why he is so skeptical, both tests skin and paraneoplastic I have had point to an autoimmune issue. So he wants to treat it as such and in hopes remove me from IVIg. I think he is foreshadowing getting grief from Aetna.
At this moment, I can only walk about a mile before my feet start giving me so much trouble that I need to sit down, but I can ride a bicycle now. I have been able to lift weights again, very lightly. What do I attribute this to? I am now taking more of my original medication and added an anti inflammatory, which whatever I may have is certainly inflammatory because the anti inflammatory really helps. IVIg is also helping me as well by removing the low energy and flu like symptoms I had before and other things I probably don't realize. Again, I may also be in one of my relapse/remit phases.
My dilemma is whether I should add something that could cause me more issues, or help or try and stay the course I am on. The neurologist says if Aetna pulls funding for the IVIg, and I am not on Imuran or Cellcept then we will be up a creek with no paddle. He says this because this would allow us to come off the IVIg and see how I do on just the Imuran or Cellcept. He also claims there is some chance for reversal?

Clinical Diagnosis

Mr. Nervous1’s diagnosis is small fiber neuropathy (ICD 9: 357.4) with autonomic neuropathy (ICD 9: 337.1) related to an autoimmune disorder (ICD 9: 279.4). He is seropositive for an autoantibody (antibody against the self) which targets neuronal tissue: the Anti-Ganglionic (-3 subunit) Neuronal Acetylcholine Receptor antibody (3-AChR Ab). This antibody is well-established to cause a clinical syndrome of autonomic neuropathy. Mr. Nervous1 has clinical symptoms which support a diagnosis of autonomic neuropathy. Furthermore, he recently underwent skin biopsy procedure, which revealed significantly reduced nerve fiber density within distal sweat glands of the lower extremity, consistent with a small-fiber autonomic neuropathy.

Intravenous immunoglobulin (IVIg) is supported by strong evidence as an effective first-line treatment of several more common immune-mediated neuropathies: chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), Guillain-Barre Syndrome (GBS), and Multifocal Motor Neuropathy (MMN). The efficacy of IVIg has been also proven in some antibody-mediated paraneoplastic neuropathies. 1

Because 3-AChR antibody-mediated neuropathy is a rare condition, there have not been large, randomized controlled treatment trials. There have been multiple published case studies showing efficacy of IVIg in patients with autoimmune neuropathy due to 3-AChR antibody. 2, 3 I feel that the best next step in Mr. Nervous1’s management would be a therapeutic IVIg infusion, at a dose of 2 grams/kg total divided over 5 days.

My History

I am 44 years old and have lifted weights and some form of cardiovascular for 23 years
I am in somewhat good health, 6’0 tall, weight 170, still exercise 3 to 4 days a week.
Autoimmune disease runs in family – Father has Addisons, Sister has Graves, Mother had IBS and liver problems, I have psoriasis and now Autoimmune Small Fiber Peripheral Neuropathy with Autonomic symptoms
Psoriasis first showed up in 1985
Symptoms of Neuropathy showed up possible as early as 2008, but Humira suppressed the symptoms.
Symptoms of the Neuropathy would come and go, almost disappear, but each time duration became longer. The symptoms have not remitted for 1 year now.
Stopped Humira in June of 2012 and symptoms increased dramatically
Started IVIg in November 2013 to current
