Dh?

Do you have to have a complete "outbreak" of DH to be tested for it? I believe DS has/had it (he is + for gluten intolerance).

Thanks-

The way understand it, the IgA deposits remain in the skin for months or even years after going gluten-free. So they should still be able to take a biopsy.

My understanding is that you have to have an active outbreak before they can take a biopsy sample.

Well, I've been looking it up and everything I find says that the biopsy should be taken from normal skin but nothing specifies whether or not there needs to be an active breakout. You should probably talk to a doctor to find out for sure, but if you're interested here are a couple of articles that I found:

"Dermatitis herpetiformis is diagnosed by a special skin test. A very small piece of skin is taken under a local anaesthetic as an outpatient procedure. The test is carried out on skin NOT affected by the rash."

"The diagnosis of DH is made by a simple skin test. A small piece of skin approximately 3 mms in diameter is taken from an unaffected area, ie. normal looking skin. The skin is examined for the presence of a substance called IgA (immunoglobulin A) and is found at a specific site in the skin. Although the test is simple, it is important a laboratory experienced in the procedure undertakes the examination of the skin. "

Hope that helps.

      My only proof

      You're right, doctors usually only test Vitamin D and B12. Both are really important, but they're not good indicators of deficiencies in the other B vitamins. Our bodies are able to store Vitamin B12 and Vitamin D in the liver for up to a year or longer. The other B vitamins can only be stored for much shorter periods of time. Pyridoxine B 6 can...

      So interesting that you stated you had sub clinical vitamin deficiencies. When I was first diagnosed with celiac disease (silent), the vitamin levels my doctor did test for were mostly within normal range (lower end) with the exception of vitamin D. I believe he tested D, B12, magnesium, and iron. I wondered how it was possible that I had celiac disease...

      Has anyone had terrible TMJ/ Jaw Pain from undiagnosed Celiac?

      Segments of the protein Casein are the same as segments of the protein strands of gluten, the 33-mer segment. The cow's body builds that Casein protein. It doesn't come from wheat. Casein can trigger the same reaction as being exposed to gluten in some people. This is not a dairy allergy (IGE mediated response). It is not lactose intolerance...

      Has anyone had terrible TMJ/ Jaw Pain from undiagnosed Celiac?

      Wheatwacked, what exactly did you intend when you stated that wheat is incorporated into the milk of cows fed wheat? Obviously, the gluten would be broken down by digestion and is too large a molecule anyway to cross the intestinal membrane and get into the bloodstream of the cow. What is it from the wheat that you are saying becomes incorporated into the...

      Wheat in cow feed would not equal gluten in the milk, @Wheatwacked, please back up extraordinary claims like this with some scientific backing, as I've never heard that cow's milk could contain gluten due to what the cow eats.

      You're right, doctors usually only test Vitamin D and B12.  Both are really important, but they're not good indicators of deficiencies in the other B vitamins.  Our bodies are able to store Vitamin B12 and Vitamin D in the liver for up to a year or longer.  The other B vitamins can only be stored for much shorter periods of time.  Pyridoxine B 6 can be stored for several months, but the others only a month or two at the longest.  Thiamine stores can be depleted in as little as three days.  There's no correlation between B12 levels and the other B vitamins' levels.  Blood tests can't measure the amount of vitamins stored inside cells where they are used.  There's disagreement as to what optimal vitamin levels are.  The Recommended Daily Allowance is based on the minimum daily amount needed to prevent disease set back in the forties when people ate a totally different diet and gruesome experiments were done on people.  Folate  requirements had to be updated in the nineties after spina bifida increased and synthetic folic acid was mandated to be added to grain products.  Vitamin D requirements have been updated only in the past few years.   Doctors aren't required to take as many hours of nutritional education as in the past.  They're educated in learning institutions funded by pharmaceutical corporations.  Natural substances like vitamins can't be patented, so there's more money to be made prescribing pharmaceuticals than vitamins.   Also, look into the Autoimmune Protocol Diet, developed by Dr. Sarah Ballantyne, a Celiac herself.  Her book The Paleo Approach has been most helpful to me.  You're very welcome.  I'm glad I can help you around some stumbling blocks while on this journey.    Keep me posted on your progress!  Best wishes!

I believe he tested D, B12, magnesium, and iron.  I wondered how it was possible that I had celiac disease without being deficient in everything!  I’m wondering now if I have subclinical vitamin deficiencies as well, because even though I remain gluten free, I struggle with insomnia, low energy, body aches, etc.  It’s truly frustrating when you stay true to the gluten-free diet, yet feel fatigued most days. I’ll definitely try the B-complex, and the Benfotiamine again, and will keep you posted. Thanks once again!
