Thank you so much for posting this. I am another person who suffered for many, many years with DH that was misdiagnosed repeatedly. I developed DH about age 7 and suffered until my late 40's being told it was everything from 'poison ivy in my blood to atopic dermatitis to 'pickers acne. After a year or so gluten free I had clear skin for the first time in my memory. Folks still struggling for a diagnosis may want to print this out to take to a derm with them. Doctors may not listen to us but might listen to the NIH.
Found this article that suggests a link between PD and the Mthfr genes (which are also associated with Celiac Disease). Taking methyl forms of B9 (methylfolate) and B12 (methylcobalamine), and B6 (P5P), makes these vitamins more usable to people with the Mthfr genes.
Celiac Disease causes malabsorption. Celiacs on a gluten free diet may develop deficiencies. (Gluten free breads and cookies are not required to be fortified with vitamins like their gluten containing counterparts.)
Perhaps adding these vitamins would be beneficial.
Hope this helps.
I'm not sure that this is the original study I looked at, but it does describe the different antibodies found circulating in the blood that is specific to DH (anti-eTG, which is analogous to anti-tTG in regular celiac disease). At any rate, it seems that they can test for it, but many labs do not have the ability to do so or doctors do not know to ask for this lab test. So I suppose if one was very interested in a diagnosis, one could go to a research centre where they would likely have the ability to test for its presence!
