HELP! should I continue the gluten challenge

[SunshineSometimes]

Hi, I am currently one week into the gluten challenge and I'm a mess!! I have had Gastro and other health issues my entire life.  In my early 20s things were getting so bad, I did an emimination diet, discovered gluten to be the culprit and cut it out.  I never planned to check for celiac, but  As I've gotten older I've found that my once occasional stomach issues I usually chalked up to accidental gluten intake were coming more and more often (bouts of sever bloating, stomach pain, diarrhea/constipation, and more recently nausea and vomiting ).  Also 2 of my four children have Gastro/other issues that improved dramatically when I almostly completely removed gluten from their diet.  Of course, as a self diagnosed anti gluten mom I'm having a hard time getting any pedesatric Drs to take my gluten concerns seriously so I decided it was time to bite the bullet and get diagnosed, or move on, so I can get going in the right direction for my kids and myself.  

    I had a biopsy scheduled for three months out and despite my gastros recommendation not to add gluten because of my sever reaction, and his assumption I was getting more gluten then I thought. I did anyway ?? ?, I just wanted to be sure.  I don't want to put my kids through a gluten challenge and all the testing unless I'm sure there is a genetic predisposition.    I started eating gluten on Sunday, resulting in normal Gastro issues and then by Tuesday I broke out in DH all over my lower back, hips, ankles, feet and fingers.  I had the rash confirmed as DH and my Gastro bumped my biopsy to today.  Here's my question, I'm concerned the biopsy is going to be negative because I've only been consuming regular amounts of gluten for one week.  I planned to at least keep eating it for another week or so in hopes of getting a positive blood test, but I'm so sick and I think the rash is starting on my arms... My dermatologist seemed to think that if I had enough antibodies to create the rash, the blood work should certainly come back positive. Is this true????  Has anyone had DH and then a negative a blood test??   I want so badly to know difenitivly  either way, and although my gastro instructed me to stop eating it, I'm tempted to continue for the blood work...... Is a positive DH rash enough??? There is so much confusing information out there!!!! 

Sorry for the long winded question!! I appreciate any help I can get ?  

Oh and I had the genetic testing done several years ago and I tested positive for a combination of them.

Welcone, @SunshineSometimes.  Have you been diagnosed with DH? I ask because DH is an instant celiac diagnosis. In other words, has an area adjacent to the rash been biopsies and come back as positive for DH?

If not, then you must continue eating gluten until all testing is complete.

Right, if you have DH, you have celiac disease.  An Endoscopy may not show anything conclusive because the immune attack is focused on the skin, not the gut.  That can change over time though.

Blood tests for other antibodies commonly found in people with celiac disease—antiendomysial and anti-tissue transglutaminase antibodies—supplement the diagnostic process.  If the antibody tests are positive and the skin biopsy has the typical findings of DH, patients do not need an intestinal biopsy to confirm the diagnosis of celiac disease.

Sorry guys but your info. is a bit out of date. If one has a dx of dh then NO FURTHER TESTING IS NEEDED. A dx of dh IS a dx of celiac disease. See:

Open Original Shared Link

Your blood would likely test false negative anyway if you have dh. Here's an excerpt:

 Many people with DH have no digestive symptoms and only about 40% of them have positive blood tests (serology) for celiac disease; however, they almost always have the same gluten-dependent intestinal damage as people with celiac disease.

And you may continue to break out even after being strict gluten-free for a while. See:

You need to be pristine in your diet!!!!!!!!!!!!!! Dh is extremely sensitive to the slightest gluten exposure!!!!!!!!!

Thanks for the quick responses!!!! My dermatologist who seems well versed about celiac and works with a Gastro on the matter told me that in very rare cases DH is not from celiac, bust since I just added gluten back Three days prior to the rash, I have celiac symptoms and my Drs suspect celiac there is really no reason to venture down other avenues.  She told me if I absolutely wanted she would biopsy the rash, but that it wouldn't confirm the rash was from celiac or not, just confirm DH, which it is 100%.  She didn't think the scar and added discomfort was worth it.  She sent all the information to My Gastro and he agreed with her.  My Gastro also seemed confident after doing my endoscopy that lab results would show something.... Will see

    Ok I'm going to hang up my web MD doctorate ?   , trust my Drs, stop eating gluten, and get my kids genetic testing! Thank u!!

Your doctors are wrong.

Read the links that @squirmingitch posted.  If you still have DH, you have the skin adjacent tested, not the lesions.  If the doctors suspect celiac then they have a 100% duty to test for DH and/or to take blood work and do an endescope.

DH is not caused by anything else but Celiac Disease. A dh biopsy, if positive for dh, would conclusively confirm DH & therefore celiac.

Dermatitis herpetiformis (DH) is a rare but persistent immunobullous disease that has been linked to coeliac disease (American spelling celiac), a Open Original Shared Link.

What causes dermatitis herpetiformis? 

• DH and coeliac disease are due to intolerance to the gliadin fraction of gluten found in wheat, rye and barley. 
• Gluten triggers production of IgA antibodies and an autoimmune process that targets the skin and gut.

************************************************************************

Dermatitis herpetiformis is a disease of the skin caused by the deposition of IgA in the papillary dermis, which triggers an immunologic cascade, resulting in neutrophil recruitment and complement activation. Dermatitis herpetiformis is the result of an immunologic response to chronic stimulation of the gut mucosa by dietary gluten.
