Intriguing Old Reserach detailing Low and No Stomach Acid in Celiacs


Posterboy

To Forum Members,

I recently was doing research in PubMed about low stomach acid and came across intriguing old research that details it's presence in/with a Celiac and DH diagnosis.

see this link

Here is the abstract in it's entirety.

Open Original Shared Link 1985 Mar;20(2):133-40.

Gastric morphology and function in dermatitis herpetiformis and in coeliac disease.

Open Original Shared Link, Open Original Shared Link, Open Original Shared Link, Open Original Shared Link, Open Original Shared Link.

Abstract

"Gastric acid secretory capacity was evaluated in 116 patients with dermatitis herpetiformis by means of the pentagastrin test. Endoscopic gastric mucosal biopsy specimens were obtained from both the body and the antrum in 90 of them. Forty-eight patients (41%) had a maximal acid output less than 10 mmol/h, and 30 of them (26%) were achlorhydric. The frequency of achlorhydria increased with age, and 27 out of 58 patients (47%) more than 50 years old were achlorhydric. Antrum-sparing chronic atrophic gastritis was present in 92% of the achlorhydric patients, and hypergastrinaemia and serum parietal cell antibodies were found in most of them. The prevalence of chronic gastritis of the body and of the antrum increased with age. There was no correlation between atrophic gastritis or achlorhydria and small-intestinal villous atrophy, the results of the D-xylose test, and blood folate and serum zinc determinations. The transferrin saturation index was lower in patients with achlorhydria. The frequency of achlorhydria was significantly higher in patients with dermatitis herpetiformis than in 69 patients with coeliac disease."

The question is what does it mean?

I see the high association between no stomach acid and DH as causal. (triggering) at 90+ percent a direct association.

But the relatively high association of Low Stomach could only be casual (associated with) but not definitely triggering but possibly causing someone with Low/No stomach acid to be diagnosed as Celiac/NCGS patients instead.

This research being 30+ years old it can be easily over looked.

I have found treating my Low Stomach acid helped my GI problems.

If it is an Esophageal pH Test could confirm your stomach acid levels.

Is this definitive research in your mind that indeed no stomach acid is triggering this immune reaction.

I was not expecting to find previous research that studied this topic.

More Recent research on PPIs indicate low stomach caused by the use of PPIs can/could trigger a Celiac diagnosis.

see this article about this topic.

Does/Is low or even No stomach acid being confused for Celiac disease today?

I would love to hear your thoughts?

I share this research in the hope that it will rediscovered again and studied again to see if it can replicated in the hopes that treating one's Low/No stomach acid might help others.

This does not mean you yourself will have low stomach acid . . but you won't know if you don't test for it.

I think with this high association in those who have received a Celiac diagnosis further testing to rule low/no stomach acid is warranted.

Share your thoughts, opinion, ideas and feedback.

I start this thread to kick start your thinking?  And to invite honest inquiry as the role stomach acid plays in GI health.

It is (low stomach/no stomach) is known to be linked/occur in chronic gastritis so it seems only logical it would at least be casual in Celiac/NCGS patient.

See this link on Chronic Gastritis and the prevalence of Low/No stomach in chronic gastritis.

Open Original Shared Link

they estimate quoting  "One may estimate that more than half of the world population have this disease in some degree and extent, indicating that even many hundreds of millions of people worldwide may have chronic gastritis in a form or other."

What if the 1/3 of the population that might develop NCGS or celiac disease is just another clinical presentation of chronic gastritis?

I think it what the research says to me . . triggered by either low or no stomach acid?

Your thoughts and comments are encouraged but I found treating my low stomach acid helped my chronic gastritis.

2 Timothy 2:7 Please Consider what this research says and may the Lord lead you on your continued journey.

I hope this research jogs your thinking.  I know it confirmed mine . . but I am open to being wrong.

A man/woman who corrects me is my friend.  I hope  this newly rediscovered research helps your thinking about how low/no stomach acid could be causing some of your GI problems forum members/friends.

We are all trying to find something that works for us and why we participate to share on this forum to help others with the same help knowledge we have gained on our way/journey God being our help.

2 Corinthians (KJV) 1:3,4  3) “Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; 4) who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble (starfish), by the comfort wherewith we ourselves are comforted of God.”

What's interesting to me is that the hypo acidity is linked to dermatitis herpetiformis but not villous atrophy. That is if I understood it correctly.

Well, I have Chronic Autoimmune Gastritis.    However, it is not linked to my celiac disease.  I just had a recent endoscopy  which revealed my CAG, but my intestinal villi were completely healed.  

 This study is pretty old, so while there  might be a connection with DH, I think the link  may be that you can have many autoimmune disorders at the same time and perhaps the presentation or cells attacked might be more comparable.  I do have Hashimoto’s too.  But with autoimmune disorders so much is unknown.  

Nice to maybe improve or increase/decrease stomach acid, but better to find out the cause, be H. pylori, autoimmine, etc.  Why do so  many people suffer from gastritis?  Most have had a H. Pylori infection which is really common.  If I recall, about 2/3 of the population has it.    This type of gastritis can be treated and cured with antibiotics.  No need to use “band aids” on this type of gastritis.  

If anyone stomach issues despite being on a gluten-free diet, do not assume it is celiac disease as the root cause.    Get it checked out.  The best way to determine Chronic Autoimmune Gastritis is to get a biopsy.

Cycylinglady and Trents,

I was hoping someone knew where the free citation for the full paper was but couldn't find it.

I did find after posting this research a much more modern and updated research on essentially the same topic in it's full citation entitled "Chronic Gastritis in Dermatitis Herpetiformis: A Controlled Study" edited by Fasano so I think it would be the gold standard.. . . or as close as we can get.

see this link

Open Original Shared Link

And what I got out of the study was a little/low stomach acid provided some protection -- No stomach acid provided no protection.

The original research math didn't match up to me (so I wanted to see the full citation.

quoting

"The frequency of achlorhydria was significantly higher in patients with dermatitis herpetiformis than in 69 patients with coeliac disease." but they started with 116 in their study.

quoting

"Gastric acid secretory capacity was evaluated in 116 patients with dermatitis herpetiformis by means of the pentagastrin test." they must mean both celiac's (without DH) and those with DH totaled 116. . but only the 69 with DH showed high correlation to no stomach acid (achlorhydria).

But back to the more modern study edited by Fasano. .. they concluded in my opinion a similar finding.

quoting there conclusion from the Fasano modern/updated study

"The present controlled study showed that patients with DH have at the time of the diagnosis a significantly increased frequency of CAG in the corpus but not in the antrum. In addition to H. pylori infection, autoimmune mechanisms may be implicated in the development of gastritis. The DH patients here did not present with any specific gastrointestinal symptoms."

Again here is the link to the modern study so as not confuse the studies.

Open Original Shared Link

They found simliar "Antrum sparing CAG" which is significant.

If you look at the chronic gastritis study.

Linked here again for convenience

Open Original Shared Link

they say "The first appearances of gastritis of the H. pylori etiology tend to be antral, i.e., gastritis is “antral predominant” [25, 27]." so in someone who does not have H. Pylori with the CAG then you would expect it to "spare the antrum" or be free of gastritis in the that part of the stomach at least initially as the stomach acid is only low at that point.

But if it continues to go down to/a the practically NO stomach acid level then you would expect the DH rate to increase with the stomach (no stomach) acid rate or lack there of in this case . . . if it is (GAC) not triggered by H. Pylori or if stomach acid helps control the auto-immune gastritis.

Of course this is before H. Pyori completely takes over the stomach.

quoting again.

"The most aggressive forms of chronic gastritis are those which result most likely in advanced stages of atrophic gastritis, i.e., are forms of H. pylori gastritis with highest likelihood to progress to the end-stage atrophy [5, 6]."

I have found like lisas11lisa “says research is your/our friend!”

the H.pylori infection itself can be limited in it's damage to the stomach lining until it directly affects stomach acid production by way of "end stage atrophy".

it is only when it spreads to the whole stomach including the "antrum" that cancer risks significantly jump up.

quoting

"The likelihood of gastric cancer in gastritis rises exponentially with the progression of the H. pylori gastritis from a non-atrophic form to an atrophic form [69]. The risk may rise even to 90-fold in patients with severe atrophic gastritis in both antrum and corpus (severe panatrophy; multifocal atrophic gastritis (MAG)) compared to the cancer risk in subjects with a normal and healthy stomach mucosa (Figure 7) [69]."

the good news if H. Pylori is triggering chronic auto-immune gastritis (CAG) then

treating the H.Pylori itself essentially controls the stomach cancer risk from CAG.

quoting again.

"A successful eradication of the H. pylori prevents ulcer recurrences but may also prevent cancers [66, 67]."

Trents I think the reason the Villous Atrophy did not correspond is that DH patients typically present with fewer GI symptoms.

they note this in the updated modern study.

quoting from the introduction

"The majority of patients with dermatitis herpetiformis (DH) evince small-bowel mucosal damage or inflammation similar to that in classic or early-stage celiac disease [1, 2]. (DH) Patients rarely suffer from abdominal symptoms, and irrespective of small-bowel mucosal morphology,  . . ."

And the reason for that is symptom's do not correspond (often) to the degree of Villous Atrophy.

See this study from the gluten free works website that talks about this very topic.

Open Original Shared Link

quoting gluten free works

"The pathologic range of villous atrophy seen on small intestinal biopsies ranges from severe (total villous atrophy and subtotal villous atrophy) to milder, partial villous atrophy.

The investigators state, “It would appear intuitive that the more severe forms of intestinal damage are correlated with the more severe and dramatic presentations.” With this in mind, one would think that those with total villous atrophy would experience more severe digestive symptoms like diarrhea. However, their study of medical records of all patients who had biopsy-proven celiac disease did not bear this out.

“Atypical, or silent, mode of presentation included anemia, osteoporosis, dermatitis herpetiformis, screening high risk groups and those detected incidentally at endoscopy performed for reasons apart from diarrhea or iron deficiency anemia.” 

It is important to note that “biopsies of the entire length of the small intestine, terminal ileal biopsies taken at colonoscopy and more recently video capsule colonscopy, reveal that the whole length of the intestine, including the large intestine, may be involved in the inflammatory process.”

And let's not forget the Villious atrophy can be patchy.

But if CAG and/or low/no stomach acid triggering CAG is common in Celiac disease then it makes sense to me . . . if my stomach is showing signs of atrophy then my/the villi in the small intestine would too.

I hope this is helpful.

*****this is not medical advice only the way I read this particular research. . . but I see them being linked conditions and not only associated conditions.

A follow up test/study needs to be done to see if correcting the stomach acid level to more robust  normal healthy level can/would then cause the villi to heal needs to be done.

Currently because the test for stomach acid is considered invasive . . .it is commonly not performed.

there is a Calcium Carbonate non-invasive breath test for Stomach acid that has been developed but it still considered experimental and not in wide use as I understand it.

here is  the abstract

The Calcium Carbonate Breath Test, a noninvasive test of stimulated gastric acid secretion: preliminary communication

Clough, Michael R.I.; Axon, Anthony T.R.

European Journal of Gastroenterology & Hepatology: Open Original Shared Link
doi: 10.1097/MEG.0b013e328321837e

"Background Gastric acid secretion is subject to complex control mechanisms, and varies widely between individuals and populations. Its measurement has previously required intubation of the stomach with ingestion of a test meal or injection of a secretion stimulant.

Aim We describe a novel method of measuring gastric acid secretion noninvasively – the Calcium Carbonate Breath Test.

Methods 13C-labelled calcium carbonate is ingested by a fasting participant. The carbonate neutralizes gastric acid to produce 13CO2, which is expired in the breath. Measurement of the excess 13CO2 in the breath allows back-calculation of the amount of gastric acid secreted during the test, provided that other variables affecting CO2 production and excretion are minimized or controlled for.

Results Studies on a single healthy individual have shown reproducible estimations of acid secretion and over 80% suppression of acid secretion after the proton pump inhibitor treatment.

Conclusion The method seems to be promising, but further studies on other individuals need to be carried out. The Calcium Carbonate Breath Test may have wide applications in epidemiological studies, clinical management of acid-related diseases, screening for hypochlorhydria and development of new acid-suppressing treatments."

It is me again.

Once this test Calcium Carbonate Breath Test for Stomach acid/ pH strength becomes widely available like the Urea Breath Test for H.Pylori

Open Original Shared Link

These conditions can be comfortably measured in a clinical setting until then/because most people don't like having a tube down their noses to get officially tested to see how strong their stomach acid really is. . . most people are never tested to see if low stomach is the cause of CAG or related to their Celiac diagnosis.

I hope this is helpful and again this is not medical advice but this research was particularly interesting too me because both the stomach acid levels and Celiac/DH was studied in the same person.

this set's precedent . . . but does not establish a causal relationship but certainly establishes casual association.  And it is worth more research/study to see if it causal.

But the high prevalence of  achlorhydria (No stomach acid) in DH patients would make me want to investigate it further with my doctor.

Sorry for the long post/reply but I had a lot of ground to cover.

as always 2 Timothy 2: 7   “Consider what I say; and the Lord give thee understanding in all things” this included

I only know treating my low stomach acid helped many of my GI problems.

It did not directly help my low nutrient levels until I supplemented with the missing nutrients my stomach/small intestine could now absorb again. . . like Magnesium, Vitamin D, Zinc and a good B-Complex etc.

see this link for appropriate supplementation in Celiacs.

Open Original Shared Link

Again I hope this is helpful and it will help some one else by the same help I found God being my help.

2 Corinthians 1: 3, 4

Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort;

Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God.

Good luck on your continued journey! The road not taken (differential diagnosis) of Low/No stomach acid misdiagnosed (or at least the concomitant condition) of achlorhydria and hypochlorydria can trigger some very similar conditions like CAG that occur in Celiac's often (I believe). . .and until you treat the one you won't know if it is causing your many symptom's you might still be having after going gluten free.

As cyclinglady said quoting

"If anyone (is having (my words added for clarity)) stomach issues despite being on a gluten-free diet, do not assume it is celiac disease as the root cause.    Get it checked out."

      I haven't been on this forum for a long time, but it was absolutely wonderful during the diagnostic process!  My path for celiac disease diagnosis was the following: -Had normal IgA level, and my only serology positive test was the DGP IgG -Deficiencies in both Vitamins D and K that did not increase at first despite massive supplementation -Diagnosis of fat malabsorption both total and neutral -Diagnosis of severe exocrine pancreatic insufficiency (EPI) -Testing was completed to rule out causes of EPI, and the only one not ruled out was celiac. -Both traditional endoscopy and pill capsule endoscopy yielded negative results for biopsy confirmation, but my GI doctor said that both procedures simply could have missed the damaged spots. -EPI and fat malabsorption resolved after taking Creon for 6 months since my EPI was caused by celiac -23 and Me said I don't have either of the two prominent genes for celiac disease   Remember that you might not have 'textbook' symptoms, but you still may have celiac disease.   Also, I am SO incredibly grateful for this site for all the learning it has allowed me to do. I have a senior dog, and these last few weeks with her were very scary! After two hospital stays, she finally received an IBD diagnosis after having gastroenteritis and pancreatitis. I know that celiac disease is not IBD, however, through reading this site, I learned more about it. I was relieved when I found out she had IBD and not cancer this past Wednesday. I know IBD can be managed thanks to what I've learned here!  So celiac.com, not only did you help me, but you helped my pup too! Thank you ❤️

      Thank you for your post, @Nedast, and welcome to the forum. It is interesting to read of your experiences. Although I've not had TMJ, from time to time I have had a bit of mild pain in my jaw, sharp stabbing pains and tingling in my face which appears to have been caused by issues with my trigeminal nerve.  I read that sometimes a damaged trigeminal nerve in coeliacs can heal after adopting a gluten free diet.  I try to keep out of cold winds or wear a scarf over my face when it is cold and windy, those conditions tend to be my 'trigger' but I do think that staying clear of gluten has helped.  Also, sleeping with a rolled up towel under my neck is a tip I picked up online, again, that seems to bring benefits. Thank you again for your input - living with this sort of pain can be very hard, so it is good to be able to share advice.

      I made an account just to reply to this topic. My story resembles yours in so many ways that it is truly amazing. I also suddenly became lactose intolerant, went a little under 10 years attributing all my symtoms to different body parts, never thinking it was something systemic until much later. I had the same mental problems - anxiety, depression, fatigue, etc. In fact, the only real difference in our story is that I was never formally diagnosed. When I discovered that my myriad symtoms, that had been continuous and worsening for years, all rapidly subsided upon cessation of consuming gluten, I immediately took it upon myself to cut gluten out of my diet completely. I live in America, and had lost my health insurance within the year prior to my discovery, so I could not get tested, and I will never willingly or knowingly consume gluten again, which I would have to do in order to get tested now that I have insurance again. But that is not the point of this reply. I also had extreme TMJ pain that began within months of getting my wisdom teeth out at - you guessed it - 17 years old. I was in and out of doctors for my various symptoms for about 5 years before I gave up, but during that time I had also kept getting reffered to different kinds of doctors that had their own, different solutions to my TMJ issue, an issue which I only recently discovered was related to my other symptoms. I began with physical therapy, and the physical therapist eventually broke down at me after many months, raising her voice at me and saying that there was nothing she could do for me. After that saga, I saw a plastic surgeon at the request of my GP, who he knew personally. This palstic surgeon began using botox injections to stop my spasming jaw muscles, and he managed to get it covered by my insurace in 2011, which was harder to do back then. This helped the pain tremendously, but did not solve the underlying problem, and I had to get repeat injections every three months. After a couple of years, this began to lose effectiveness, and I needed treatments more often than my insurance would cover. The surgeon did a scan on the joint and saw slight damage to the tissues. He then got approved by insurance to do a small surgery on the massseter (jaw) muscle - making an incision, and then splicing tissue into the muscle to stop the spasming. It worked amazingly, but about three months later it had stopped working. I was on the verge of seeing the top oral surgeon in our city, but instead of operating on me, he referred me to a unique group of dentists who focus on the TMJ and its biomechanical relationship to teeth occlusion (i.e. how the teeth fit together). This is what your dentist did, and what he did to you was boderline if not outright malpractice. There is a dental field that specializes in doing this kind of dental work, and it takes many years of extra schooling (and a lot of money invested into education) to be able to modify teeth occusion in this manner. Just based on the way you describe your dentist doing this, I can tell he was not qualified to do this to you. Dentists who are qualified and engage in this practice take many measurments of your head, mouth, teeth, etc., they take laboratory molds of your teeth, and they then make a complete, life-size model of your skull and teeth to help them guide their work on you. They then have a lab construct, and give you what is called a "bite splint." It looks and feels like a retainer, but its function is entirely different. This is essentially a literal splint for the TMJ that situates on the teeth. The splint is progressively modified once or twice per week, over several months, in order to slowly move the joint to its correct position. The muscles spasm less, stress is taken off the joint, as the joint slowly moves back into its proper position. The pain reduces each month, each week, sometimes even each day you go in for a visit. The joint has to be moved in this manner with the splint BEFORE the modification to the teeth begins. They then add to your tooth structure with small bits of composite, to keep the joint in its proper place after it has been sucessfully repositioned. Subtracting from your teeth, by grinding down bits of your natural tooth structure, is done very conservatively, if they have to do it at all. This process worked for me - after six months, my face, jaw, neck all felt normal, and I had no more pain - a feeling I had not had in a long time. It also made my face look better. I had not realized the true extent that the spasming muscles and the joint derangement had effected the shape of my face. The pain began to return after a few months, but nowhere near where it had been before. This immense reduction in pain lasted for a little over two years. The treatment still ultimately failed, but it is not their fault, and it is still the treatment that has given me the most relief to this day. Later on, I even went about three years with very, very good pain reduction, before the joint severely destabilized again. This field of dentistry is the last line treatment for TMJ issues before oral surgery on the TMJ. There aren't as many denists around who practice this anymore, and the practice is currently shrinking due to dentists opting for less espensive, additional educations in things like professional whitening, which have a broader marketability. Getting this treatment is also very expensive if not covered by insurance (in America at least). My first time was covered by insurance, second time was not, though the dentist took pity on me due to the nature of my case and charged like a quarter of usual pricing. Most cases seen by these dentists are complete successes, and the patient never has to come back again. But occasionally they get a case that is not a success, and I was one of those cases. A little over a year ago, I began seeing the second dentist who keeps my TMJ stable in this manner. The first dentist retired, and then died sadly. A shame too, because he was a truly amazing, knowledgable guy who really wanted to help people. The new dentist began to get suspicious when my joint failed to stay stable after I was finished with the bite splint and his modifications, so he did another scan on me. This is ten years after the first scan (remember, I said the surgeon saw "slight" damage to the tissue on the first scan). This new scan revealed that I now no longer have cartilage in the joint, on both sides - complete degeneration of the soft tissues and some damage to the bone. The dentist sat me down and had a talk with me after these results came in, and said that when he sees damage like this in cases like mine, that the damage to the joint is most likely autoimmune, and that, in his experinece, it is usually autoimmune. He has sent patients with cases like mine to Mayo Clinic. He said he will continue to see me as long as the treatment continues to offer me relief, but also said that I will probably have to see a dentist for this type of treatment for the rest of my life. He is not currently recommending surgery due to my young age and the fact that the treatment he provides manages my symptoms pretty well. I still see this dentist today, and probably will see this kind of dental specialist for the rest of my life, since they have helped with this issue the most. I did not inform him that I am 100% sure that I have celiac disease (due to my complete symptom remission upon gluten cessation). I didn't inform him because I thought it would be inappropriate due to not having a formal diagnosis. I was disappointed, because I had believed I had caught it BEFORE it had done permanent damage to my body. I had never suspected that my TMJ issues may be related to my other symptoms, and that the damage would end up complete and permanent. Luckily, I caught it about 6 months after my other joints started hurting, and they stopped hurting right after I went gluten free, and haven't hurt since. I of course did the necessary research after the results of the second scan, and found out that the TMJ is the most commonly involved joint in autoimmune disease of the intestines, and if mutliple joints are effected, it is usually the first one effected. This makes complete sense, since the TMJ is the most closely related joint to the intestines, and literally controls the opening that allows food passage into your intestines. I am here to tell you, that if anyone says there is no potential relationship between TMJ issues and celiac disease, they are absolutely wrong. Just google TMJ and Celiac disease, and read the scientific articles you find. Research on issues regarding the TMJ is relatively sparse, but you will find the association you're looking for validated.
