Dermatitis Herpetiformis

I'm new here, although in the past I know I've read some of the messages.   My doctor and I have long suspected that I have celiac. I have several other autoimmune illnesses. But, my celiac biopsy was negative, so I started eating a lot more gluten.  Over the last several years, I've had minor bouts of an extremely itchy rash that I was correlating to gluten, but it wasn't very bad and would improve in a short amount of time. Last year, I had a bout that was a bit worse, but it went away rather quickly, so I didn't think too much about it. Fast forward to this year. I have had a REALLY BAD case of it, for a few months, so I went to a dermatologist, and she diagnosed dermatitis herpetiformis without a biopsy. It was pretty obvious to her that it is dermatitis herpetiformis, but she said that if I wanted her to, she would do a biopsy. She said that I have just become more sensitized over time. She prescripbed Dapsone gel, which helps a lot, but I run out of it long before I'm eligible for a refill. So, I am going CRAZY. It is on my arms, legs trunk, everywhere, and it itches like chiggers. If I get even the slightest bit sweaty, it is so unbearable. I've been 100% gluten free since April, but it keeps flaring up. (I've been under intense stress, too.)  My questions are:  1.) Do many people have celiac without a positive celiac biopsy?  2.) How long will the dermatitis herpetiformis persist, even though I'm 100% gluten free? 3.) Is my story a common one?

Thanks so much!

Welcome to the forum, @Pamp8!

As to your first question, it is possible to have only the epidermal form of celiac disease but it is not common. Most people who have dermatitis herpetiformis also have damage being done to the villous lining of the small bowel. 

As to your second question, most likely you are getting some gluten contamination from an unknown source on occasion that you are unaware of and are not suspecting. It could be something like in a medication or supplement you are taking or an oral hygiene product you are using or a spice you are using in your cooking. You might also look into a low iodine diet as iodine is known to exacerbate dermatitis herpetiformis.

As to your third question, many who suffer from dermatitis herpetiformis find it is a stubborn problem and difficult to completely control.

Hi there @Pamp8  yes I've had dermatitis herpetiformis and a negative test for celiac and a negative biopsy. I had stopped eating gluten before taking the test.  I have had an inconclusive genetic (?) test.  I developed the same all body rash.  It was one of the worst experiences of my life and I am sorry you're experiencing it.  What helped me: 1). I stopped eating oats of any kind. 2). I also took some anti-biotics that were not prescribed for dermatitis herpetiformis but I read they could help. 3). Salty food exacerbates it for me. 

Now I have a small flare up any time I get cross contamination like from french fries or a shared grill at a restaurant but it's not as bad as it used to be.  Wishing you relief soon.

Welcome to the forum, @Pamp8,

I stopped foods high in iodine, like dairy and eggs, kelp and iodized salt.  

I take Niacinamide also called Nicotinamide or Vitamin B3.  I haven't taken the tetracycline with it.   It seems to make the blisters disappear quicker.

I also use tallow balm, a cream made from beef fat, which has been used for thousands of years.  It is absorbed into the skin better than creams made from plants.  It helps prevent or lesson scarring.  See the study below.

Two Cases of Dermatitis Herpetiformis Successfully Treated with Tetracycline and Niacinamide

"The combination of tetracycline and nicotinamide can be recommended as a useful therapy for patients where dapsone is not available or for patients who do not tolerate dapsone."

I would hesitate to recommend tetracycline or any antibiotic as a long term therapy option because of the negative impact it has on the gut biome. I took it for years as a teenager for acne and I'm convinced it was a contributing factor in my having developed celiac disease.

I would not be surprised if that is the case. I briefly took doxycycline and it cleared up but I also stopped eating oats at the same time so hard to say what did it. And I understand doxy is nasty stuff. I had to take it with yogurt because it messed up my stomach so badly.

Thank you for all of these helpful answers!  I really appreciate them. I typically eat 2 eggs every morning, so I'm going to stop those, in case the iodine is an issue. And, I'm checking all of my medications and supplements for gluten. I will try some of these other suggestions, too. Thank you all. I feel like I have a little bit of hope that this can get better soon.

Our son was put on Minocycline for his acne.  It did not solve the acne problem.  He developed drug induced lupus and pericarditis from it and missed an entire year of high school.  He literally went from playing football to bedridden in a couple of weeks.  His PCP tested him for genetic antibiotic resistance and he cannot take any drug in the Tetracycline family.  His gut microbiome was totally destroyed.  In fact he had a stool test done and had no good bacteria, whatsoever.  

What did fix his (and his brother's acne) years after the Minocycline debacle was when I was diagnosed with Celiac disease and the kids were tested.  They were both put on a Gluten Free/ Caesin Free diet and within a week both kids were totally free of acne.  The family has now been on the diet 18 years and no acne, except for a teenage grandson who will not adhere.  The big clue that he is eating gluten is that his face breaks out!

      @Celiac50, Other than finding foods that make your tummy happy, are you feeling well?  No other symptoms?  That's great progress! You don't mention vitamin D status.  Vitamin D deficiency in the UK has been estimated to be as high as 60% of the population. Celiac Disease causes depleted oral vitamin D from malabsorption.  Most people do not get enough UV light to activate skin creation of vitamin D. Vitamin D supplementation in the United Kingdom: time for change Vitamin D Is Not as Toxic as Was Once Thought It looks like you are going to have to try changing out food by food, until you find the one.  Start with the supplements.      Wild caught vs. farm raised?  Sometimes it is just a subtIe change that can do it. I know that switching to grass fed milk has been good for me.

      The incidence of autoimmune diseases in general, including celiac disease, has increased.  There are various theories as to why. The environment we live in, diet we eat, toxins we’re exposed to, stress levels, activity levels and infectious diseases to which we are exposed are all quite different now. A robust immune system that would have been an advantage thousands of years ago may be a bit too robust for modern life.

      @Celiac50, Most Celiac patients with a Marsh score as high as yours are more likely to suffer from fat malabsorption and deficiency in fat soluble vitamins, Vitamins A, D, E, and K.   Vitamin A toxicity does not cause Celiac disease.  Your Vitamin A toxicity was probably developed after your diagnosis and subsequent over-supplementation.  Fish contains thiaminases, chemical compounds that destroy thiamine, Vitamin B 1, making the thiamine unusable.  Excessive intake of foods containing thiaminases can precipitate low thiamine.   Low thiamine can also be a result of bacterial or yeast infections.  A high carbohydrate diet encourages Candida and bacterial infections.  High carbohydrate diets promote SIBO and Candida because they feed on the excess carbohydrates and suppress the beneficial bacteria.  Other types of bacteria can take advantage of this and set up housekeeping outside the gastrointestinal tract, including bacterial vaginosis. Thiamine Vitamin B 1 can alter the microbiome.  Thiamine has been shown to suppress Candida, SIBO, and other bacterial and viral infections, and favor the growth of beneficial bacteria.  My SIBO cleared once I supplemented with Benfotiamine, a form of thiamine that has been shown to promote intestinal healing, and a B Complex.  Thiamine works in concert with the other B vitamins and magnesium. Thiamine helps to lower histamine levels by calming mast cells that release histamine at the slightest provocation.   Following the Autoimmune Protocol diet also helped immensely in getting my digestive system calmed and able to tolerate more foods. Have you discussed with your doctor and dietician supplementing essential B vitamins while healing?  What is your Vitamin D level?  Vitamin D helps calm the immune system.

      Has anyone ever had Low Ferritin with Elevated MCHC levels?

      By cristiana · Posted

      Update - my Active B12 is 36.  Apparently lab results between 25 and 70 suggest a possible deficiency, anything below 25 is a confirmed deficiency, above 70 is normal.   I am thinking this could be the explanation for my elevated MCHC. Anyway, yet again I find myself bumping along the levels of low normal by British NHS standards, which isn't great, because from what I understand, in the UK our normal levels are set low and 'lower normal' levels would be considered a deficiency in such countries as Germany and Japan. Regarding B12 levels, it doesn't look as if my levels are low enough to be offered B12 injections.  That being the case, I remember reading that sublingual tablets can still be very effective but one particular type is better than another - I can't remember which type.  Can anyone help?

      Hi @Celiac50 If you are after a vitamin A test - sorry - I'm tired so not sure if I'm reading this correctly - perhaps you could try a home test?  I'm in the UK and am currently a bit perplexed about my own vitamin issue and thinking of going to a private lab for tests.  My issues is suboptimal Active B12 (only 11 marks off deficient) but no health professionals seem to be taking any interest in it although this is  my fault as last time I saw my Consultant I failed to mention my symptoms - I had so many other questions to ask him.  Anyway - here are the details for an A test: https://www.medichecks.com/products/vitamin-a-retinol-blood-test?gad_source=1&gad_campaignid=11996732820&gbraid=0AAAAAD9XHFyeAOrxlryOpWS_jXwZ8PCc1&gclid=EAIaIQobChMIyrjj2Pb2jwMVnJJQBh22CTkVEAAYASAAEgIGDPD_BwE
