How To Tell The Difference Between Dermatitis Herpetiformis And Scabies?

Hi

 

New user here, I apologize if this question is posted often (I don't frequent forums and am somewhat unsure how to use this!)

 

I am a 25 year old female who recently started showing symptoms of a a DH rash on my body (on my lower back, buttocks, upper thighs, elbows, and then a few randomly on my legs and arms) for about 4 months now, and it has gradually gotten worse

 

I have suffered from eczema and sensitive skin all my life, and initially put it to be just that. However when they did not go away I researched a bit online and found my rash to match up almost exactly with dermatitis herpetiformis.

 

However, I was also wondering how to tell the difference between dermatitis herpetiformis and scabies.

I have heard scabies is very contagious and I have had this rash for some time now and no one in my friends and/or family have contracted anything! However, I would still like to rule out scabies to be safe.

You can go to a derm & get a skin scraping which they look at under a microscope to see either a mite or the egg. If they dx by looks alone, they may be wrong so if you want to know for sure make sure they do a skin scraping for the scabies.

scabies  also  run in a line  of  three often  start  around  the  ankle  area...can be  just a bout  anywhere on the  body  but  tend  to be in a line  of  three... I  think of it  as a  trail like  a  mole  would  make  in the yard.....You  should  see a  doctor  for  a  scraping.... honestly I never  thought the two  resembled  each other..

No but derms dx dh as scabies all the time.

While you're there you should insist on a dh biopsy. Make sure it's done correctly as 99% of the time they do it wrong. It MUST be taken from CLEAR skin ADJACENT to a fresh, active lesion.

Print these out & take them & give them to the derm so they will know how to correctly do it.

If you get a positive biopsy of dh then you have celiac disease & no further testing is needed. Continue to eat a full gluten diet until the biopsy results are in. Do NOT take any oral steroids or get any steroid injections in the 2 months prior to the dh biopsy.

 

Go over to the dh forum & read, read, read as many threads as you can.

      Edy's and Dreyer's ice cream

      By Aretaeus Cappadocia · Posted

      Sigh. I posted this yesterday based on the Safeway website. I went back again today to their website to double check. On the page where they are selling Vanilla Bean flavor, it has a distinct Certified Gluten Free label. Other flavors on the Safeway website didn't have the gluten-free statement. Today I went into the store. None of the flavors I looked at, including Vanilla Bean, have a Gluten Free statement. Is it safe? Who knows. The ingredients are either safe or nearly safe (some have "natural flavor"). There are warnings about "contains milk and soy" but not about wheat - this implies they are safe, but again, who knows. On the other hand, every flavor I checked of their Slow Churn line of ice creams has wheat as an ingredient. 100% not safe.

      Do keep in mind that many of the newly diagnosed have lactose intolerance.  This is because the villi lining the intestinal tract are damaged, and can no longer make the enzyme lactAse which breaks down the milk sugar lactOse.  When the villi grow back (six months to two years), they can again produce the enzyme lactAse, and lactose intolerance is resolved.  However, some people (both those with and without Celiac Disease) are genetically programmed to stop producing lactase as they age.   Do be aware that many processed foods, including ice cream, use Microbial Transglutaminase, a food additive commonly called "meat glue," used to enhance texture and flavor.  This microbial transglutaminase has the same immunogenicity as tissue transglutaminase which the body produces in response to gluten in people with Celiac Disease.  Tissue Transglutaminase (tTg IgA) is measured to diagnose Celiac Disease in blood tests.  Microbial Transglutaminase acts the same as Tissue Transglutaminase, causing increased intestinal permeability and inflammation.   New findings show that microbial transglutaminase may be able to trigger Celiac Disease and other autoimmune and neurodegenerative diseases.   Microbial Transglutaminase is not required to be listed on ingredients labels as it's considered a processing aid, not an ingredient in the U.S.  Microbial Transglutaminase has been GRAS for many years, but that GRAS standing is being questioned more and more as the immunogenicity of microbial transglutaminase is being discovered. Interesting Reading:  Microbial Transglutaminase Is a Very Frequently Used Food Additive and Is a Potential Inducer of Autoimmune/Neurodegenerative Diseases https://pmc.ncbi.nlm.nih.gov/articles/PMC8537092/

      There is a 10 year old post in this forum on Edy's and Dreyer's ice cream. The information is somewhat outdated and the thread is closed to further comment, so here is a new one. Edy's And Dreyer's Grand Vanilla Bean Ice Cream - 1.5 Quart is labeled "Gluten Free". This is a different answer than years gone by. I don't know the answer for any other flavor at this moment. On 1 May, 2026, Edy's website says: "As a general rule, the gluten in Edy's and Dreyer's® frozen dessert products is present only in the added bakery products, such as cookies, cake or brownies. We always label the eight major food allergens on our package by their common name. We recommend to always check the label for the most current information before purchasing and/or consuming a product. The exception to this rule is our Slow Churned French Silk frozen dairy dessert, which contains gluten in the natural flavors." https://www.icecream.com/us/en/brands/edys-and-dreyers/faq It seems that Edy's and Dreyer's are more celiac-friendly than they were 10 years ago. Once I found enough information to make today's buying decision, I stopped researching.

      probably not your situation @Mimiof2, but allow me to add one more to @trents list of celiac-mimics: "olmesartan-induced sprue-like enteropathy"

      Terrible Neurological Symptoms

      My dad had an Abdominal Aortic Aneurysm.  Fortunately, it was discovered during an exam.  The doctor could feel my dad's heart beating in his stomach/abdomen.  The aneurysm burst when the doctor first touched it in surgery.  Since he was already hooked up to the bypass machine, my dad survived ten more years.  Close call! Triple A's can press on the nerves in the spinal cord causing leg pain.  I'm wondering if bowing the head might have increased the pressure on an aneurysm and then the nerves.   https://gulfcoastsurgeons.com/understanding-abdominal-aortic-aneurysm-symptoms-and-causes/ Abdominal Aortic Aneurysm Presenting as a Claudication https://pmc.ncbi.nlm.nih.gov/articles/PMC4040638/
