On the horizon: Fecal testing for dietary compliance

It looks like it won't be too long before we have a new method of testing for dietary compliance and it appears it's going to be more accurate/sensitive than the present serum tests.

At this link, there is an interview with Ivor D. Hill, MD, MB ChB; Alessio Fasano, MD.

I would point you to page 4 of that. Some of you may not be able to access the linked page. You can sign up for Medscape, it's free and that's what I did, then you can access all of their articles.

The following is part of what both Dr. Hill said and what Dr. Fasano said:

Dr. Hill:

A very interesting paper has just come out in the American Journal of Gastroenterology,[4]in which a group from Spain looked at gluten immunogenic peptides in the stool and documented that you can actually identify these in the stool. People think that, based on dietary review, they are completely gluten free. That may be something in the future that will give us a very good test, and I am excited about the possibility that we will actually be able to detect gluten immunogenic peptides in the stool and know that the patient is still being exposed, as opposed to relying on dietary review, symptoms, and TTG testing.

 

Dr Fasano: To echo what Ivor has said, we do have a concern. The same Spanish group presented a follow-up of evidence of the robust performance of this test for immunogenic peptides in stool at the World Congress in Montreal.[5] I am as impressed as Ivor that this might be a very objective, strong way to monitor for inadvertent exposure to gluten.

 

Here are links to the studies they are referring to and the results:

I think this might be a good idea for those who do not trip antibody blood testing.  However, I noticed that Dr. Hill made the remark: "as opposed to relying on dietary review, symptoms, and TTG testing."  You do not use tTg as a test for dietary compliance. We all know you have to do a repeat DGP, in those who were diagnosed using blood antibody testing. DGP is pretty damn sensitive so why they keep omitting this is beyond me.  :rolleyes:  Personally, I would rather have a blood draw than do stool testing but I do agree this would be great for a certain subset of Celiac patients.

I wonder if this might have diagnostic use at some point. It would be nice to have a way to diagnose without a challenge for those that are already gluten free.  Also wonder if this is similar to the fecal testng that Enterolab does.

I agree Gem, I would rather have a blood draw but yes, there are those who don't test positive on the serum.

I don't know if Dr. Hill just screwed up when he said TTG or if that was a typo. It could easily be either. I am astounded beyond measure at the amount of typos in the professional world these days. It seems everything you read has at least a couple. The incorrect grammar is appalling! No one proofreads anymore. That's one thing when it's something casual but something entirely different when it's journalism or a professional article.

I'm going to hope for a gluten-sniffing dog!  Funny, my 5th grader's science project was about cancer sniffing dogs.  During her presentation, she used our labrador to demonstrate.  She trained our dog to identify food masking as "cancer cells".  It was hilarious!  Our dog actually did it!  

Anyway, I can't agree more with Gemini about the TTG measuring dietary compliance.  I continue to test negative to the TTG.   I think the DGP should be included in helping to determine dietary compliance.  

Finally, I was saddened to hear that Dr. Fasano's recent research showed that some 20% of children are not experiencing intestinal healing.  We know from other studies that some 2/3 of  adult celiac patients never heal.  It is disheartening!  More post-diagnosis research and better tools to manage celiac disease are desperately needed.

I don't think so Raven. This is detecting the peptide in gluten not antibodies against gluten.

      Diagnosis and further testing Celiac

      By Redanafs · Posted

      Hi everyone. Back in 2022 I had blood work drawn for iga ext gliadin. Since then I’ve developed worse stomach issues and all other health issues. My doctor just said cut out gluten. He did no further testing. Please see my test results attached. I just need some direction cause I feel so ill and the stomach pain is becoming worse. Can this test show indications for other gastrointestinal diseases?

      Thank you. These were the results TTG ABS NUMERICAL: > 250.0 U/mL [< 14.99]  Really don’t understand the results!

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      Clearly from what you've said the info on Dailymed is much more up to date than the other site, which hasn't been updated since 2017. The fact that some companies might be repackaging drugs does not mean the info on the ingredients is not correct.

      To evaluate the TTG antibody result we’d need to know the normal range for that lab.  Labs don’t all use the same units.  However, based on any normal ranges that I’ve seen and the listed result being greater than a number rather than a specific number, I’d say yes, that is high! Higher than the range where the test can give a quantitative result. You got good advice not to change your diet yet.  If you went gluten free your intestines would start to heal, confusing any further testing,

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Bev in Milw · Posted

      Scott is correct….Thank you for catching that!      Direct link for info  of fillers.    http://www.glutenfreedrugs.com/Excipients.htm Link is on 2nd page  of www.glutenfreedrugs.com   Site was started by a pharmacist (or 2) maybe 15-20 yrs ago with LAST updated in  2017.  This makes it’s Drug List so old that it’s no longer relevant. Companies & contacts, along with suppliers &  sources would need to be referenced, same amount effort  as starting with current data on DailyMed      That being said, Excipient List is still be relevant since major changes to product labeling occurred prior ’17.           List is the dictionary that sources the ‘foreign-to-us’ terms used on pharmaceutical labels, terms we need to rule out gluten.    Note on DailyMed INFO— When you look for a specific drug on DailyMed, notice that nearly all of companies (brands/labels) are flagged as a ‘Repackager’… This would seem to suggest the actual ‘pills’ are being mass produced by a limited number of wholesaler suppliers (esp for older meds out of  patent protection.).      If so, multiple repackager-get  bulk shipments  from same supplier will all  be selling identical meds —same formula/fillers. Others repackager-could be switching suppliers  frequently based on cost, or runs both gluten-free & non- items on same lines.  No way to know  without contacting company.     While some I know have  searched pharmacies chasing a specific brand, long-term  solution is to find (or teach) pharmacy staff who’s willing help.    When I got 1st Rx ~8 years ago, I went to Walgreens & said I needed gluten-free.  Walked  out when pharmacist said  ‘How am I supposed  to know…’  (ar least he as honest… ). Walmart pharmacists down the block were ‘No problem!’—Once, they wouldn’t release my Rx, still waiting on gluten-free status from a new supplier. Re: Timeliness of DailyMed info?   A serendipitous conversation with cousin in Mi was unexpectedly reassuring.  She works in office of Perrigo, major products of OTC meds (was 1st to add gluten-free labels).  I TOTALLY lucked out when I asked about her job: “TODAY I trained a new full-time employee to make entries to Daily Med.’  Task had grown to hours a day, time she needed for tasks that couldn’t be delegated….We can only hope majorities of companies are as  conscientious!   For the Newbies…. SOLE  purpose of  fillers (possible gluten) in meds is to  hold the active ingredients together in a doseable form.  Drugs  given by injection or as IV are always gluten-free!  (Sometimes drs can do antibiotics w/ one-time injection rather than 7-10 days of  pills .) Liquid meds (typically for kids)—still read labels, but  could be an a simpler option for some products…
