Pre Diagnosis

Hi there. I’m new to this group and looking for some answers so would be grateful for any comments. 
I have suspected that I may have Celiac for some years now. 
initially I had a severe rash on my shins which was unbearably itchy. At the time I was unaware of dermatitis herpetiformis so never considered celiac as a diagnosis. I attended the GP but after trying numerous medications without any success, and no diagnosis, I continued to have flare ups of this for a number of years. It eventually subsided but following a routine appointment for fatigue and low mood my GP did blood tests and established iron and folate deficiency. This was treated but after short periods of improvement it has recurred several times. I was referred for endoscopy and colonoscopy about 4 years ago and these did not flag up any issues. At this time a biopsy was taken for celiac but it was clear. (That said, prior to the procedure I was on a restricted diet and would not have had much gluten intake). Blood tests have not identified celiac either. I have not had many gastrointestinal issues aside from soft unstructured and fatty stools and an urgency to go to the toilet. I have now come out in a clustered blister type rash on my back, shoulders and bottom. It is symmetrical on both sides but is not itchy at all. The GP has been unable to diagnose this and has made a dermatologist referral for me. Blood tests identified folate and iron deficiency again. Other symptoms include visual disturbance and brain fog with lack of concentration and extreme fatigue. I had attributed many of these symptoms to menopause but just wondered if It is possible that I could have celiac disease as HRT has not alleviated my symptoms. How difficult is it to diagnose? And what are my next options?

Celiac disease is not difficult to diagnose but you must be eating meaningful amounts of gluten prior to any kind of testing. Here is what the Mayo Clinic guidelines are:

For the serum antibody tests: The daily consumption of gluten in the amount equivalent to at least 2 slices of wheat bread for 6-8 weeks leading up to the blood draw.

For the endoscopy/biopsy: The daily consumption of gluten in the amount equivalent to at least 2 slices of wheat bread for at least 2 weeks prior to the procedure.

If you cut back on gluten prior to testing, the inflammation in the small bowel lining begins to subside. The inflammation is what produces the antibodies that the serum test is designed to detect. Likewise, if you cut back on gluten prior to the endoscopy/biopsy it may allow healing of the villi lining the small bowel such that damage doesn't show up in the microscopic lab analysis of the samples taken. Also, many physicians do not do a thorough job during the scoping and don't take enough samples from enough areas. Damage can be patchy and easily missed. We recommend several samples be taken from both the duodenum and the duodenum bulb.

When seeking the antibody tests, as for total serum IGA, ttG-IGA and Deamidated gliadin peptide (DGP IgA and IgG).

You certainly have a lot of symptoms that could point to either celiac disease or NCGS (Non Celiac Gluten Sensitivity). NCGS is 10x more common than celiac disease and shares many of the same symptoms. A dx of NCGS requires first ruling out celiac disease. The antidote is the same for both: total avoidance of gluten for life.

Thank you so much for your comprehensive reply. It’s a great help.

By the way, aghasue, welcome to the forum!

Since you have a referral to a dermatologist, I would ask him to do a skin biopsy for dermatitis herpetiformis.

Hi RMJ - I will suggest this to him. However it is my understanding that dermatitis herpetiformis is always extremely itchy and the rash I have at the moment is not. Can you have dermatitis herpetiformis without the itchiness?

I don’t know, but there is a DH forum as part of celiac.com - you might ask there.

      Coeliac or not coeliac

      By Russ H · Posted

      Do you have the standard range for the test results you received? A level of anti-tTG2 antibodies at least 10x the standard range is almost certainly (>98%) due to coeliac disease. Moderately raised levels can be caused by other conditions as well as coeliac disease. Accuracy of the No-Biopsy Approach for the Diagnosis of Celiac Disease in Adults: A Systematic Review and Meta-Analysis It is possible to have latent or early stage coeliac disease without histological changes visible by microscope. As has been suggest in this thread, if the repeat test comes up negative and serology is high, request an HLA genetic test from your specialist. Only 40 % of the population carries an HLA gene variant enabling the development of coeliac disease - if you test negative for this, it is quite unlikely that you have coeliac disease.

      The Struggle Has Overtaken Me

      By Wheatwacked · Posted

      Hi @Ginger38, By now you know that these things improve without gluten. I once saw an interview with a corporation executive where he proudly declared that his wheat products are more addictive than potato chips. Dr Fuhrman (Eat to Live) said find foods that are friendly to you to be friends with.

      Hi @CC90 Ah... that is very interesting.  Although it is very annoying for you to have to go through it all again, I would say that almost sounds like an admission that they didn't look far enough last time?   I could be wrong, but I would not be at all surprised if they find something on the next attempt.  Coeliac damage can be very patchy, as I understand it, so that's why my own gastroenterologist always likes to point out that he's taken lots of samples!  In the kindest possible way (you don't want to upset the person doing the procedure!) I'd be inclined to tell them what happened last time and to ask them in person to take samples lower down, as  if your health system is anything like the one in my country, communication between GPs, consultants and hospitals isn't always very good.  You don't want the same mistake to be made again. You say that your first endoscopy was traumatic?  May I ask, looking at your spelling of coeliac, was this done at an NHS hospital in England?  The reason for the question is that one of my NHS diagnosed friends was not automatically offered a sedative and managed without one.  Inspired by her, I tried to have an endoscopy one time, in a private setting, without one, so that I could recover quicker, but I had to request sedative in the end it was so uncomfortable.    I am sorry that you will have to go through a gluten challenge again but to make things easier, ensure you eat things containing gluten that you will miss should you have to go gluten free one day. 😂 I was told to eat 2 slices of normal wholemeal bread or the equivalent every day in the weeks before , but I also opted for Weetabix and dozens of Penguin chocolate biscuits.  (I had a very tight headache across my temple for days before the procedure, which I thought was interesting as I had that frequently growing up. - must have been a coeliac symptom!)  Anyway, I do hope you soon get the answers you are looking for and do keep us posted.

      Hi Cristiana   Yes I've had the biopsy results showing normal villi and intestinal mucosa.  The repeat endoscopy (requested by the gastro doc) would be to take samples from further into the intestine than the previous endoscopy reached.

      Transglutaminase IgA is the gold-standard blood test for celiac disease. Sensitivity of over 90% and specificity of 95–99%. It rarely produces false positives.  An elevated level means your immune system is reacting to gluten.  Non-Celiac Gluten Sensitivity (NCGS) does not typically cause high levels of tTG-IgA. Unfortunately the protocols for a diagnosis of Celiac Disease are aimed at proving you don't have it, leaving you twisting in the wind. Genetic testing and improvement on a trial gluten free diet, also avoiding milk protein, will likely show improvement in short order if it is Celiac; but will that satisfy the medical system for a diagnosis? If you do end up scheduling a repeat endoscopy, be sure to eat up to 10 grams of gluten for 8 - 12 weeks.  You want  to create maximum damage. Not a medical opinion, but my vote is yes.
