SFSN Diagnosis Just In
 

Ok folks, hot off the press, went to see Dr. Norman Latov to get my results. 99.9% bloodwork normal--not even close to pre-diabetes. That was a relief. However they picked up that I was fairly deficient in B6, which he feels strongly is the root cause of the neuropathy. He said the skin biopsy revelead a mild to moderate small fiber neuropathy. Here are the numbers, feel free to talk amongst yourselves:

Diagnosis: Lt Cal, Epidermal Nerve Fiber Density: Skin with significantly reduced epidermal fiber density, consistent with small fiber neuropathy.

Lt. Thigh: Skin with normal epidermal nerve fiber density

Numnbers were

Lt Calf = 2.6 Abnormal is <5.4 Low Normal= 5.4 - 5.7
Left Thigh = 11.53 Abnormal is <6.8 and low normal is 6.8 - 8.0


No evidence of vasculitis or other histological . No amyloid detected by the Congo Red stain (I had asked for a Congo Magenta stain, but I was denied--that is a joke, please don't ask your doctor for this).

So he said that 50 mg B6 (and I think he also said I can also take niaminicide or something?) would have to be taken for at least a year. I had started with p-5-P per Mrs. D. He was fine with that. He also said it could resolve itself, but it would take at least a year to find out. Hard to predict, but he definitely felt that it will not progress to motor or autonomic (99% was the number he used), for which I was very grateful.

I also have these suspicious looking white spots on my hands....he commented that it could be vitiglio (sp). Great, I am turning into Michael Jackson. Latov laughed and asked if I wanted a glove--I told him the sequins would not look good on the surgical gloves he had. At that point, he asked whether I had sores or burning in my mouth (I did and thought I had BMS). He said that will abate over time as well...the guy is expensive, but he is good.

So, now onto my favorite topic. Pain management. 3,600 mg of Gabapentin, and it ain't doing the trick. So, he said that Cymbalta has a synergestic effect with Gabapentin. Since my knowledge of neurochemistry is limited to dissecting a pig in my bio class 30 years ago, I nodded sullenly and agreed with him. At that point, the pig had nothing to say either. So, 20mg, building up to 4 X per day. He said I could get relief from lower dose, but see how it goes. Not sure he liked my joke about frying bacon on my extremities...I think he keeps Kosher.

Thanks to everyone for listening. This has been quite the humdinger thus far. Figuring out what caused the B6 deficiency is the real rub (could coumadin have caused this?!???). Don't know, but hope all is well with everyone.

Good to hear that you have a diagnosis, be sure to report if B6 is helping you.
I have read your symptoms and they are remarkably similar to mine. I also feel good when I stand, but when I sit - especially after exercise - oh boy!
My EMG/MRI/bloodwork is normal. Did the previous doctor you went to not pick up your B6 deficiency?
Also, do you have flares of burning, every few weeks/days?
Did he say anything in general about how is he able to tell whether SFN would progress to autonomic/motor or not?

thanks.

Well...
 

basically good news.

However, no reason for why your B6 is low?

You know that you cannot drink with Cymbalta.
It is is only antidepressant that damages the liver.

Effexor is similar but safer.

mark, good news, I am happy for you, Idiopathic pn comes from somewhere, I think the percentage of idiopathic would be reduced if most people went to a pn specialist. This goes without saying, patients have to be their own advocates. If I remember you went to a couple of docs, and got a couple of different opinions. I think Cymbalta is a anti depressant too, Well keep us informed, hope you feel better lynn

Mark, great news. Your doctor sounds wonderful. Unfortunately, they first neurologist I saw, who by the way was a specialist in PN, was a real disappointment.

I wasn't even tested for a B6 deficiency, and being a newbie, I didn't know much about it. I finally lined up my appointment for a second opinion, and I fully intend to do things differently. One of the drugs that I was taking when I was stricken with PN was Hydralazine, 75mg a day. If you do a search on it on the net, it is listed as preventing B6 absorption into the body. When I brought this up to my regular doctor, he said he never heard of that, and my blood pressure specialist said that would be very rare for that to happen. I still insisted on stopping that drug.

So is it a fact that when it is proven that a drug did cause ones neuropathy, it can in some cases be reversed, or improved, or at the very least stop the progression?

[edit] Deficiencies
The classic clinical syndrome for B6 deficiency is a seborrheic dermatitis-like eruption, atrophic glossitis with ulceration, angular cheilitis, conjunctivitis, intertrigo, and neurologic symptoms of somnolence, confusion, and neuropathy.[5] Pyroluria is one cause of vitamin B6 deficiency.

While severe vitamin B6 deficiency results in dermatologic and neurologic changes, less severe cases present with metabolic lesions associated with insufficient acitivities of the coenzyme pyridoxal phosphate. The most prominent of the lesions is due to impaired tryptophan-niacin conversion. This can be detected based on urinary excretion of xanthurenic acid after an oral tryptophan load. Vitamin B6 deficiency can also result from impaired transsulfuration of methionine to cysteine. The pyridoxal phosphate-dependent transaminases and glycogen phosphorylase provide the vitamin with its role in gluconeogenesis, so deprivation of vitamin B6 results in impaired glucose tolerance.[2]

this is from Wiki......note the comment about niacin conversion

also...
 

can you take a picture and post your white spots on the hands?

Concerning vitiligo:
from http://www.medicinenet.com/vitiligo/article.htm

Are the white spots scars from red patches? Did you have lesions there before? Like bug bites, etc?

One cause of low B6 is pyroluria. This is a genetic defect in the making of heme in the liver, where a byproduct is made called kryptopyrrole. This compound sequesters B6 and zinc and causes rapid loss thru the urine. If you have this, you will also be losing zinc.

This is important because males need zinc because they lose it
thru the seminal fluid. Low zinc makes the body more susceptible to infection, esp by viruses.

How expensive is Dr. Latov? how can I get an appointment with him?
Do you have to wait long time for a meeting?

Thanks

Flare ups....yep...I got em.

And Hope re "So is it a fact that when it is proven that a drug did cause ones neuropathy, it can in some cases be reversed, or improved, or at the very least stop the progression?"

The answer to the above is yes. Progression can stop definitely....he said the symptoms can least a year or more, and I might just go numb (my wife would already say I am,but that is a different story). He said I should see improvement....

Thanks Mark. I am at the beginning of this journey with PN, and I just do not know what to think. Can it really have been the Hydralazine I ask myself? The doctors act like no way. Then I ask myself could it be my upper spine and neck of which I have trouble with? Then again, I have symptoms in my face and I don't know if neck and back problems could send signals there. My appointment at the university hospital isn't for two weeks, so I want to be ready and ask for these tests. How wonderful it would be to know the cause and hope that improvement can follow...

Sorry to ramble....:o
