Hi,

I recently went to the doctor with some health issues and they are doing blood tests, stool tests etc. I forgot to mention this as it’s only just flared up.

See pics. For a few years I’ve been getting these spots on my elbows, and less often knees. It comes and goes every few months or so, sometimes slightly itchy but never really to the itchy extent I think people with eczema get. It’s always worse on one elbow/knee. 
 

Any help will be massively appreciated.

Hi @Marshmallow99 and welcome to the forum!

I don't see the little clear blister heads, but certainly the areas where you are affected, and the general look, are consistent with DH, so you may want to get to a dermatologist who can biopsy for DH. The process is very specific, and must be done correctly, so be sure to ask them beforehand if they can do this.

Have you every had a blood panel done for celiac disease? DH is the skin manifestation of celiac disease.

Hi @Scott Adams

Thanks very much for your helpful reply. Sorry picture quality isn’t great due to upload size, I’ve attached another if that’s any better.

 

It’s now gotten worse on my other elbow and knee, and more itchy. It’s been coming and going over 2 years. 

 

Think I have had a blood panel, possibly not celiac directly but not sure. This year and 2 years ago went to Dr saying I had bowel problems, bloating etc and have felt like something is wrong in the stomach area for years, either to do with the gut or female things (bad periods and associated symptoms).

 

On my recent blood test tissue transglutaminase IGA levels were at 0.5 U/mL, as they were 2 years ago, and from reading think that is a negative result for celiac disease? 

 

Other options I’ve looked at are eczema or ‘granuloma annulare’. If there is any other advice you could give that would be appreciated. Thank you

It looks like it could be DH, but again, to be sure you'd need to see a dermatologist.

Do you have the full results, and the scale used on your TTG test? I can't really comment on it without more info, as the scale used changes depending on the lab used.

      Dangerously underweight, Perfect gluten free and insomnia

      knitty kitty makes a good point. Avocados are high in histamines. So are bananas. Both also trigger histamine production in the body when consumed so there's a double whammy with those two foods for those struggling with histamine intolerance/MCAS

      3 years with Celiac, now I appear fine.

      @Sharke, The updated guidelines for a gluten challenge are to eat ten grams of gluten per day for two weeks minimum.  Lesser amounts of gluten (3 grams) don't provoke an immune response strong enough that the antibodies leave the gastrointestinal tract and get into the blood where they can be measured in tTg blood tests.   Have no doubt that the antibodies made in the small intestine are doing damage there, even if you don't suffer severe symptoms, yet. Did you react to barley prior to going gluten free? Have you been checked for chronic autoimmune gastritis which is another autoimmune disease that sometimes occurs with Celiac Disease? Have you been checked for nutritional deficiencies?  Thiamine deficiency (Gastrointestinal Beriberi) can cause constipation and/or diarrhea, abdominal pain, and weight loss.   Thiamine Deficiency Disorders https://pmc.ncbi.nlm.nih.gov/articles/PMC8451766/

      Family education

      @sillyyak52, Count another one in the same boat!  My family has always been in denial.  They said my tummy aches were a ploy to miss school.  My parents passed from health problems associated with uncontrolled Celiac Disease (Abdominal Aortic Aneurysm and Glioblastoma brain tumor).  My sister still has her head buried in the sand.   I agree with @Rogol72, try the consequences of untreated celiac disease shock treatment.  Sometimes people are just scared of having to change their comfortable lifestyle.

      Can food allergies like milk and soy flatten villi?

      By Lotte18 · Posted

      I have never been tested for tTg 6 antibodies but I will certainly do that next time I'm at the doc's.  Maybe there's a home test kit for that?  I drink lactose free milk and seem to be ok so I'm probably not a casein case but...who knows?!

      Gluten Ataxia and Malabsorption

      By knitty kitty · Posted

      I take Life Extension brand Mega Benfotiamine, (250 mg with each of two meals) and Maxlife Natural TTFD-B1 Max Thiamine (100 mg).   I try to take my Benfotiamine and TTFD before four pm, otherwise I have so much energy, it can be hard to fall asleep.
