Dh Without Celiac Gene?

Does anyone who does not have a major celiac gene have confirmed DH? I have a friend who is gluten "sensitive" but does not have the classic celiac gene. He recently cheated and three days later woke up with bumps that look like little bug bites with a water blister at the head. (The genetic test looked only for the classic "celiac" genes and not any for those for gluten intolerance.) I'm just wondering if DH is even a possibility to consider.

DH usually shows up faster - my DH pops up within 30 minutes (which is handy, as I don't eat too much of the bad stuff!) I was told by my doctor that it is possible to have DH and not have the Celiac gene. I was diagnosed purely through the skin biopsy, nothing internal, and since I've been gluten-free for almost a year now, they don't want to go messing with my diet.

Also, DH is usually symmetrical - if it pops up on one elbow, it doesn't take long to pop up on the other. If it would make him feel better knowing for sure, he should make an appointment with a dermatologist and eat some wheat before he goes in to make sure he will be nice and rashy when he goes to see the doctor.

Yep. Me. I had it severely for many long miserable years. In my childhood I was told I had poison ivy 'in my blood stream' to explain why I would be covered summer and winter. After I went gluten free I would get the kind of breakouts you describe. At first they would appear in hours but after a couple of years gluten-free it now takes me about 3 to 4 days to get the one or two little blisters I now get. After folks have been gluten-free for a bit the antibodies leave the skin and the reaction can take longer to show up.

Me too-- I am DQ6 and DQ7. I have confirmed DH and it pops up within an hour, I would say, of getting glutened. I can pop up anywhere-- if it is on an arm, say, I can actually watch it form.

Since the research has a ways to go regarding genetic sequences, the answer must be yes.

(And of course, the above posts show same)

Just last month, a study was published saying they'd found 7 more genetic "areas of interest" for celiac disease.

It is also interesting to know that many people who are diagnosed as celiac (via biopsy or dietary response or bloodwork) do not get the genetic test done and do not know what their genes are. If more people who are sick got the test, I think the ideas about the DQ2 and DQ8 genes, as well as the reported percentages, would change drastically.

Maybe your friend can get a biopsy with next rash and therefore a diagnosis. I was told that DH is considered a definitive celiac diagnosis.

I just read at the www.thefooddoc.com site that some labs miss the celiac genes because they do not test the apha chains, thus missing the half DQ2 genes that some have there. He lists which labs do the whole test.

      Thankyou. I have cyclosporine 0.05% OP single use drops and Erythromycin ophth ointment 3.5 Gmail for eyes. Dermatologist gave Pimecrolimus cream 1% and Clobetasol Propoonate USP 0.05% it doesn't help at all.i do see a difference taking Yarrow Pom but its too expensive!

      What would you do - neighbor brought gluten-free pizza from Papa Murphy's

      When the pizza was dropped off she told me it had a Udi's certified gluten-free crust. Even so, I am trying to play things as safe as possible for at least the next 6-months. With that said, I returned the two slices to my neighbor and asked her to thank her mom for the pizza. 😊 I will likely bump into my neighbor's mom sometime next week. She sh...

      I take Niacin, bilberry, Omega threes, zinc, selenium, and Vitamins C and A for eye health, skin health and digestive tract health.  The skin, digestive system and eyes are all derived from basically the same sort of cells.  Niacin is extremely important to keeping these tissues healthy.    Niacin has be shown to prevent cataracts and improve eye health.  Niacin is turned into tryptophan which is necessary to heal the digestive tract.  Tryptophan is used to make Serotonin, a very important neurotransmitter in mood regulation.  Those with Niacin insufficiency become irritable and easily upset, angry, even. Niacin improves skin health.  The flushing of Niacin opens the smallest blood vessels in the skin so that waste products can more easily be removed.  I have Dermatitis Herpetiformis.  Niacin helps drain away those built up antibodies in the blisters and improve skin health.   Bilberry contains lutein and zeaxanthin and other anthocyanins,  potent antioxidants that help protect the eyes from macular degeneration and cataracts.  Bilberry has sGLT1 and GLUT2 which help to lower glucose levels by removing excess glucose from the bloodstream.  High blood glucose levels are bad for eye health.   Omega Threes are important to provide relief in dry eyes.  You are familiar with how oil floats on water.  Same thing happens with eyes.  Omega threes provide the oily layer that protects water from evaporating from the eyes causing dry eyes.  Omega threes in olive oil, sunflower seed oil,  and flaxseed oils will help improve dry eyes. Vitamin A and Riboflavin B2 are important in this function as well.   None of the medications I was given improved my dry eyes.  I increased my Omega threes and Vitamin A, and had improvement very quickly. Selenium and zinc are important in skin and eye barrier functions, too, and are important to preventing infections. When I take 100 mg of Niacin every three hours (but not more than 500 mg/day), my skin and eye health improves.  If one is deficient in Niacin, the flushing effects may be uncomfortable, but ride it out, continue taking Niacin and the flushing goes away as niacin stores inside cells are repleted.  When flushing, don't scratch!  Use pressure applied over a bigger area above the itch.  I wrap up in a towel or blanket to create the counter pressure.  The flushing goes away the longer one takes Niacin.  Don't use Niacinamide (the non flushing form of Niacin).   Other vitamins that improve eye health are Vitamin E and Pyridoxine B6 and Thiamine B1.  Most Vitamin E sold is derived from wheat germ, so find another source of Vitamin E.  I used Evening Primrose oil, also a source of healthy Omega threes and helps with female problems like perimenopause  and menopause symptoms. Do be aware that antifungals and antibiotics (as are frequently prescribed) destroy Thiamine.  Immunosuppressive drugs can suppress production of tTg antibodies.  Supplementing with thiamine above the RDA is safe and nontoxic.  RDA were set as the lowest amount to prevent illness.  Optimal health is seen in higher amounts.   Do talk to your doctor and dietician about supplementing essential nutrients.   References: https://pubmed.ncbi.nlm.nih.gov/39183990/ https://pubmed.ncbi.nlm.nih.gov/41156490/ https://pmc.ncbi.nlm.nih.gov/articles/PMC7602486/

My impression so far is the NAC is doing good.  Best with meal.
