RfC: Claims of link between medical conditions and WP:WEIGHT[edit]

Does a simple (single sentence) claim of a link between medical conditions, in a large article, need to be "fully established" or "definitive" to not run afoul of WP:WEIGHT or any other policy? (Assuming it meets the requirements of WP:MEDRS.) Int21h (talk) 05:17, 9 June 2013 (UTC)

  • Coeliac disease has been associated with a very large number of conditions. Int21h has decided to emphasise one (atopic dermatitis) of many associated skin conditions in their edits. I don't think that is the right way of going about it. The only classically associated skin condition is dermatitis herpetiformis. JFW | T@lk 22:12, 10 June 2013 (UTC)
    • So am I to understand you assert an association must be a "classic association" to be mentioned on Wikipedia? Int21h (talk) 04:17, 11 June 2013 (UTC)
      • You are twisting my words. Please don't do that. JFW | T@lk 20:48, 24 June 2013 (UTC)
  • if a link between conditions is to be mentioned, then there must be a good reason why other linked conditions are *not* mentioned. So if there are multiple conditions of at least as certain association as the one currently mentioned, we should either mention all or none. Quantum Burrito (talk) 23:21, 20 June 2013 (UTC)
This is a tentative link at best as discussed above. Maybe if we had a subpage these less significant details could be discussed there. Doc James (talk · contribs · email) (if I write on your page reply on mine) 20:53, 24 June 2013 (UTC)
  • If this article can get into very technical details about tissue transglutaminase and epitopes which go way over the head of over 99.9% of readers, I don't see why it can't discuss things which are much more relevant to the average reader such as associated medical conditions. The proposed edit adds stuff about eczema; however, the cited review by Caproni et al 2012 discusses psoriasis after DH and says "among the inflammatory skin diseases improved by gluten-free diet, psoriasis is one of the most important". It follows with overviews of alopecia areata, chronic uticaria, hereditary angioneurotic edema, cutaneous vasculitis, and finally atopic dermatitis. I suggest citing Caproni et al with a more balanced overview of the skin conditions the reviewers feel are noteworthy. At the same time, Wikipedia articles improve iteratively. For example, someone probably didn't try to keep out the details on prolamins on the basis that, say, the diet section lacked details. II | (t - c) 03:32, 25 June 2013 (UTC)

External links[edit]

I don't know where to put this comment so I'll put it here. In the history section there's a brief reference to the diet proposed in 1924 by Sydney Haas with the comment: "This diet remained in vogue until the actual cause of coeliac disease was determined." But the diet is still very much 'in vogue' in a more developed form referred to by Haas as the Specific Carbohydrate Diet. It was presented by Haas in 1951 in his medical textbook 'The Management of Celiac Disease'. So I'm suggesting that a link should be provided to the Wiki article 'Specifi Carbohydrate Diet' which discusses this form of the diet and also discusses a 1987 book for laypeople which is still in print and which lists thirteen web sites devoted to the issue. This 1987 book had been translated as of 2005 into seven languages, a good indication that many people have found the diet useful. In fact the diet addresses a whole range of digestive problems, not just coeliac disease.

Until recently, the article had several useful external links to reliable, professionally-written websites with relevant extra information that could be useful to interested readers and future editors (e.g. the US NIH). This has been removed and replaced with a link to "DMOZ", which appears to be a vague web directory of oddly chosen non-professional websites. I tried to restore the professional medical links, but they were removed and the DMOZ link replaced, with the claim that this is in line with WPMED consensus. Can someone enlighten me as to where WPMED stipulates we must replace reliable medical resources with strange web directories? Arripay (talk) 00:48, 22 September 2013 (UTC)

WP:NOT states we are not a collection of external links. The great think about DMOZ is that one can go there and help improve the links they have if you deem they are not professional. Doc James (talk · contribs · email) (if I write on your page reply on mine) 11:35, 22 September 2013 (UTC)
Let me get this straight - this is not a collection of external links, so we should link to a collection of external links. We can then edit the other site's collection of links, but we can't do that directly on wikipedia - the website on which I am actually an editor. Nope, still making no sense to me I'm afraid. The manual of style for medicine-related pages says of external links: "Disease-related organisations and government health departments sometimes produce web pages containing substantial information that would be of interest to readers wishing to further study the topic. Such links are chosen for the information content, not because the organisation is particularly worthy or helpful." This perfectly describes the links that were there (NIH etc). That's been changed to link to a bunch of irrelevant stuff. It baffles me that anyone could see that as an improvement. Arripay (talk) 23:27, 22 September 2013 (UTC)
None of the links really contains anything our article does not already discuss. Doc James (talk · contribs · email) (if I write on your page reply on mine) 12:31, 23 September 2013 (UTC)
May as well delete all of them, then. Arripay (talk) 19:21, 24 September 2013 (UTC)

Updates in Genetics in reference to Evolutionary History[edit]

I would like to make the following changes to the final paragraph in the Genetics subsection so the paragraph reads:

The prevalence of CD genotypes in the modern population is not completely understood. Given the characteristics of the disease and its apparent strong heritability, it would normally be expected that the genotypes would undergo negative selection and to be absent in societies where agriculture has been practised the longest (compare with a similar condition, Lactose intolerance, which has been negatively selected so strongly that its prevalence went from ~100% in ancestral populations to less than 5% in some European countries). This expectation was first proposed by Simoons (1981).[1] By now, however, it is apparent that this is not the case; on the contrary, there is evidence of positive selection in CD genotypes. The DQ2.5 haplotype, in certain tests did not show a preference for positive selection but, 4 out of the network of 40 CD related genes showed a positive selection.[2] The four genes are also risk factors for other diseases such as Crohn’s, Type 1 diabetes, and other autoimmune/inflammatory diseases.[2] It is suspected that some of them may have been beneficial by providing protection against bacterial infections.[3][4] One particular loci, SH2B3 when in a homozygous patient, allows for a higher concentration of cytokines responsible for inflammatory responses. This observation further suggests that the four loci with a positive selection may play a role in fighting infection but makes individuals more susceptible to autoimmune diseases like coeliac.[2]

End of edit[edit]

My reasoning for this change is to update the proposed cause of coeliac. What was present in the article wasn't completely correct and I believe this expands on why this disease is still prevalent despite its negative effects. Please let me know what changes you would suggest either here or on my talk page. Thanks.

Note: The reference numbers should changed once the edit is made. If I messed that up, please let me know.

Tcs46 (talk) 02:04, 31 October 2013 (UTC)

Per WP:MEDRS we typically use secondary sources rather than primary sources. This is a primary source [1]]. Can you make these changes? Thanks Doc James (talk · contribs · email) (if I write on your page reply on mine) 12:42, 31 October 2013 (UTC)
The article you linked to is already present in the article and was not added by me. Tcs46 (talk) 15:14, 31 October 2013 (UTC)
I'm not finding it. It would be helpful if you would use PMIDs (and add them to your suggested text to make it easier to review your sources). For example, I do not see PMID 19805228 in the current article. SandyGeorgia (Talk) 19:03, 31 October 2013 (UTC)
OK, I found and tried to fix the problem, and failed so I archived the old sections. That primary source was not in the article-- but it was being pulled into the ref list here on talk because it was discussed elsewhere on this talk page. I fixed it by changing the reflist parameter in this talk section and archiving the old talk sections. There is a reference template that will pull only from the current section on talk, but I don't know where to find it-- perhaps someone else will fix it. SandyGeorgia (Talk) 19:16, 31 October 2013 (UTC)

Proposed change[edit]

So, you've included the entire current para above with your changes. Is it correct that your proposed change is adding these two sentences (for which I have corrected your citation of Abadie to the style used in the article):

  • The DQ2.5 haplotype, in certain tests did not show a preference for positive selection but, 4 out of the network of 40 CD related genes showed a positive selection.[5] The four genes are also risk factors for other diseases such as Crohn’s, Type 1 diabetes, and other autoimmune/inflammatory diseases.[5]
  • One particular loci, SH2B3 when in a homozygous patient, allows for a higher concentration of cytokines responsible for inflammatory responses. This observation further suggests that the four loci with a positive selection may play a role in fighting infection but makes individuals more susceptible to autoimmune diseases like coeliac.[5]

I am not following why you want to add these two sentences, but perhaps DocJames or Jdfwolff will. SandyGeorgia (Talk) 19:31, 31 October 2013 (UTC)

They add clarification to the genetic history. The paragraph before the change made it seem that the haplotype was positively selected for. This is incorrect. 4 other genes within the network are positively selected for and this change gives an example to show their significance in other diseases related to coeliac. Tcs46 (talk) 18:46, 1 November 2013 (UTC)
If clarification was the intent, perhaps one of the other editors here can reword in such a way that that is achieved. SandyGeorgia (Talk) 18:48, 1 November 2013 (UTC)

Selenium and thyroid disease[edit]

3AlarmLampscooter added a discussion about doi:10.4415/ANN_10_04_06. This seems to pose a number of theories about why autoimmune thyroiditis is linked with coeliac disease, and places hyposelenaemia at the centre of the hypothesis. As SandyGeorgia suggests, this is not something that has made its way into the major reviews on coeliac disease. The theory is probably too obscure to discuss here with such certainty (WP:WEIGHT is the relevant policy). If stronger sources can be provided, this can be revisited. JFW | T@lk 20:50, 17 December 2013 (UTC)

  • The link between coeliac disease and low selenium levels was published in the BMJ all the way back in 1985. Nature Endocrinology published a review last year calling selenium deficiency "likely to constitute a risk factor for a feedforward derangement of the immune system". While benefits of actually supplementing selenium in either case is still a very controversial topic and perhaps should be left out, I think it's pretty clear selenium is a legitimate factor in the diseases, and all the explained pathways between selenium, coeliac and thyroiditis in the 2010 review I cited checked out fine to me. 3AlarmLampscooter (talk) 14:13, 18 December 2013 (UTC)
PMID 22009156 is a recent review; Jfdwolff may have better information about the journal. SandyGeorgia (Talk) 17:36, 18 December 2013 (UTC)
My concern is that the recent reviews don't mention this link directly. The only source that unequivocally claims that in coeliac disease, the predisposition to thyroid disease is mediated by hyposelenaemia is the obscure review in Ann Ist Super Sanità. Selenium status may be abnormal in coeliac disease, but can we say with confidence that it is a causal relationship? I think the fact that this hypothesis is not followed by any other reviewer is sufficient to exclude it from this very broad article.
Unfortunately I have no access to the Nat Rev Endocr review (doi:10.1038/nrendo.2011.174), but if it does not mention coeliac disease explicitly I don't think it's going to help us much. JFW | T@lk 19:30, 18 December 2013 (UTC)
Funny how fast things can progress, the new version of Clinical Gastroenterology just came out a few days ago, now citing the Stazi and Trinti paper on the link to autoimmune thyroiditis. Highlights include "Micronutrient screening for zinc, copper, and selenium should be performed at least annually and sooner, if deficiency is suspected" and "CD patients deficient in selenium may complain of generalized fatigue and muscle weakness. Physical exam and labwork may reveal low serum selenium levels, hypertension, cardiomyopathy, elevated transaminases, autoimmune thyroid disease, and perhaps even psychiatric manifestations (schizophrenia)". I'd say at this point we should update the article to reflect this. Any objections 3AlarmLampscooter (talk) 17:17, 20 December 2013 (UTC)
I am happy to mention selenium deficiency with doi:10.1007/978-1-4614-8560-5_11 as a reference, but it doesn't seem that this source says that hyposelenaemia is the cause of the thyroid disease, so I don't think I can support any claims to that effect. JFW | T@lk 23:14, 21 December 2013 (UTC)

Hwp1 proposed to be included in the transglutaminase section[edit]

Hwp1 should be added to the Coeliac Disease transglutaminase section page.

I think Hwp1 (Candida Albicans protein) is as required to be cited in the Coeliac Disease page of Wikipedia as VP7 (Rotavirus protein). VP7 is greatly related to Coeliac disease, but Hwp1 too.

VP7 is cited in the Coeliac Disease Wikipedia page and Hwp1 is not.

Moreover, VP7 is cited in the transglutaminase section when VP7 is NOT so far defined as a transglutaminase substrate. Hwp1 has been proven as a transglutaminase substrate, It has also been clearly associated with celiac disease by the homology between Hwp1 and gliadin.

The three references below has been considered by Doc James as Not suitable to allow Hwp1 to be included.

1) Staab JF, et al. (1999) Adhesive and mammalian transglutaminase substrate properties of Candida albicans Hwp1. Science 283:1535-1538

2) Nieuwenhuizen WF, et al. (2003) Is Candida albicans a trigger in the onset of coeliac disease?. Lancet 361: 2152–54

3) Sakly W, Thomas V, Quash G, El AS. 2006. A role for tissue transglutaminase in alpha-gliadin peptide cytotoxicity. Clin. Exp. Immunol. 146:550–558

But these three references show that:

1) Hwp1 is a transglutaminase substrate.

2) Hwp1 share homology in primary sequence with gliadin.

3) Gliadin is a transglutaminase substrate.

4) Hwp1 and gliadin enter human body by the same route: oral route and transglutaminase acts on both gliadin and Hwp1 being this transglutaminase action related to associated diseases (Coeliac Disease and Candidiasis respectively)

5) Hwp1 and gliadin are cause of diseases in human oro-esapho-gastro-intestinal system.

6) Hwp1 (Candidiasis) and gliadin (Coeliac disease) related diseases share histophatological tissue damage characteristics.

7) Hwp1 is a Candida Albicans virulence factor in Candididasis disease and gliadin is the causative agent of coeliac disease.

8) Removing of Hwp1 (hwp1 knockout mice experiments) is related with significantly reduced virulence and removing of gluten

I think that the eight proven facts above do Hwp1 inclusion in the transglutaminase section of Coeliac Disease page of WIkipedia neccesary to have a complete understanding of the relationships in this disease.

The truth is I still do not understand why these references are invalid having been published in prestigious publications like Science or Lancet.

Hello FOTGCREN, I think I need to clarify why I reverted your edit[6] despite your use of secondary sources. I think you might be falling foul of WP:NOR/WP:SYNTH, suggesting an association that can only be supported by sources if you extrapolate stuff from them. If I search PubMed with MeSH "MAJR" headings "celiac disease" and "candida albicans" only a single paper comes up (PMID 12826451). When I review citations to this paper in Scopus, it has received some citations but not in the core reviews of coeliac disease in any of the major journals. I think it is a theory that has not been sufficiently investigated to be suitable for inclusion on this page.
I am not at all clear whether "Alternative Medicine Review" is a WP:MEDRS, by the way. JFW | T@lk 11:43, 28 February 2014 (UTC)
Oh, and FOTGCREN, your personal website[7] seems to concede that this is still a hypothesis. It's not common for encyclopedia articles to discuss hypotheses that are awaiting proof, unless the proof has been elusive and the hypothesis has received extremely widespread attention (e.g. the Higgs boson). JFW | T@lk 11:54, 28 February 2014 (UTC)
First of all, thanks for the clarifications. I agree with almost everything you say. Anyway, there is a fact, two proteins, Hwp1 and gliadin, its primary sequences are available in UNIPROT.,, It is simple. Compare them. Protein structure define protein function and enzyme substrate ability. Primary sequence has its role in building structure of proteins. It is not a definitive proof but it is very suspicious. Maybe not so suspicious as the fact that after Nieuwenhuizen, research on these issues does not exist. Maybe does not interest that were to conclude that the cereals couln´t be a human food. I´ll try one last editting trying to accomplish all requirements about "WP:NOR" and "WP:PRIMARY" — Preceding unsigned comment added by FOTGCREN (talkcontribs) 13:38, 28 February 2014 (UTC)
Oh, and maybe the Higgs boson hypothesis, like searching what is the exactly number of stars in the universe be an hypothesis that has received extremely widespread attention. To me it has no interest compared with the minimun possibility of knowing how any food you eats everyday could be the cause of any disease that affects you in the future. Thats is important to me. Not the Higgs Bosson. I suppose I'm a rare guy. Thanks anyway for your time.

Well, I better thought that I am going to leave the decission of adding these two references on you Doc,do what you think is best;
It was shown by the dutch Ph.D. Willem Nieuwenhuizen in the year 2003 that gliadin has homologous sequences of amino acids when it is compared to Candida albicans hyphal wall protein 1 (hwp1). This is indicated in the review: “New Insights in Celiac Disease”.
Branski D. New Insights in Celiac Disease. RMMJ 2012;3 (1):e0006. doi:10.5041/RMMJ.10073
T cell epitopes related to celiac disease were shown having homologies with aminoacids into the sequence of the Candida albicans hyphal wall protein 1 (hwp1). This is indicated in the review: “Innate and Adaptive Immunity against Candida spp. Infections in the Gastrointestinal Tract”
Wagner (2005). "Innate and Adaptive Immunity against Candida spp. Infections in the Gastrointestinal Tract". Fungal :Immunology: 303–321.
Put these links or not say it did not seem right not to add them with reference to the review of Williams 2013 indicating that Hwp1 is a substrate of transglutaminase.
Hyphal wall protein 1 (Hwp1; encoded for by the HWP1 gene) is a protein involved in Candida Albicans adhesion to epithelial cells and this protein is perhaps the most widely studied adhesin of C. albicans. Glutamine residues in the N-terminal domain of Hwp1 can be cross-linked to unidentified host proteins by host transglutaminase activity and this leads to covalent attachment of the yeast to host epithelial cells. This interaction has been shown to be important for Candida albicans colonisation within the oral cavity
Williams DW, Jordan RP, Wei XQ, Alves CT, Wise MP, Wilson MJ, Lewis MA (2013)."Interactions of Candida albicans with host epithelial surfaces". J Oral Microbiol.doi:10.3402/jom.v5i0.22434.
Yet when VP7 is not a transglutaminase substrate proved (to date). And VP7 is broadly cited in this page.
Thanks for all.

FDA issued final regulation for gluten free[edit]

The FDA issued final regulation for gluten free last year [11]. The article should be updated to reflect that.Jasonhein1 (talk) 23:25, 20 February 2014 (UTC)

I have updated the citations for the final rule and added a citation to the codified regulations. The mention of the (proposed) regulations was already in the #Diet section next to the Codex Alimentarius mention. Int21h (talk) 17:34, 21 February 2014 (UTC)
I should also note that the Food Allergen Labeling and Consumer Protection Act of 2004 (the law requiring regulation of the term "gluten-free") also requires wheat to be identified prominently on labeling. The European Union also has some analogous regulations, somewhat explained here and here, which discusses the background of Commission Delegated Regulation (EU) No 1155/2013, which was published November 2013 and amends Regulation (EU) No 1169/2011, with implementing regulations to come later; "gluten-free" had been regulated in the EU since 2009 with Commission Regulation (EC) No 41/2009, which will be repealed by Regulation (EU) No 609/2013 effective July 2016. Int21h (talk) 19:26, 21 February 2014 (UTC)
Those are some interesting links. There should be more coverage on gluten-free labeling in the US given the market size for the product. Also, FALCPA said that gluten-free should have been finalized by 2008, but wasn't which perturbed the celiac community. Also, there's no mention of the CSA certification seal, or GFCO's GF seal.Jasonhein1 (talk) 22:27, 21 February 2014 (UTC)

Increasing incidence?[edit]

The article suggests that there may not be a real rise in prevalence, it was simply underdiagnosed in the past: Historically, coeliac disease was thought to be rare, with a prevalence of about 0.02%.[88] Recent increases in the number of reported cases may be due to changes in diagnostic practice.[89]
Recent studies seem to contradict that view.

How can you ensure that these are not the results of increased testing? JFW | T@lk 21:33, 23 February 2014 (UTC)

Change to lead[edit]

Hi, people, as this is a featured article I feel the need to get consensus on a change to the lead I would like to make. The change I would like to make is the following; the first sentence currently reads:
"Coeliac disease (/ˈsiːli.æk/; celiac disease in the United States[1] and often celiac sprue) is an autoimmune disorder of the small intestine that occurs in genetically predisposed people of all ages from middle infancy onward."

I think the article would benefit if I was to change this sentence to:
"Coeliac disease (/ˈsiːli.æk/; celiac disease in the United States[1] and often celiac sprue) is an autoimmune disorder of the small intestine that occurs in genetically-predisposed people of all ages in response to dietary consumption of gluten."

As I think it's important to get to the crux of the disease in the first sentence and part of this is the fact that gluten is the precipitating factor in CD sufferers. Plus I may not be an English teacher but I'm pretty sure in British English we're meant to use hyphens when two words are woven together in the sentence. I am Australian so British English is meant to be second nature to me. Thoughts? Fuse809 (talk) 03:19, 20 March 2014 (UTC)


I had celiac and a very restricted diet as a small child. It was explained to me later by a relative (chief of staff at a major hospital) that children often outgrow celiac or at least its symptoms. Indeed, I have observed no diet restrictions for decades since early childhood, eat great quantities of wheat products, and as far as I know have no symptoms of the condition whatsoever. I think remission should be discussed in the article. — Preceding unsigned comment added by Econprof (talkcontribs) 04:35, 13 April 2014 (UTC)

Hello Econprof. Current thinking is that people who are rechallenged with gluten will usually relapsed. If you believe that it can be "outgrown", I suggest you present a high-quality secondary source here (see WP:MEDRS) to support that assertion. Thanks! JFW | T@lk 19:50, 13 April 2014 (UTC)

Other pathological findings[edit]

Humpath added content based on doi:10.1309/AJCPE89ZPVJTSPWL. This is unfortunately a primary source. There are several recent secondary sources specifically about coeliac disease pathology (doi:10.5858/arpa.2011-0572-RA and doi:10.1016/j.giec.2012.07.001) that might be better sources.

Cross-reaction between gliadin and different foods[edit]

A subgroup of coeliac disease patients continues to experience symptoms even on a gluten-free diet. The list of foods which can cause coeliac symptoms is long and includes: rice, corn, yeast, dairy and many other popular gluten-free products. I heard that coeliac disease patients are advised to remove all of them from their diet.

I think there should be a significant section in the article or even a separate article on that issue. I'm not an expert and I can't do that myself, so I ask all more competent people to consider my suggestion. Thanks. — Preceding unsigned comment added by Agnes86 (talkcontribs) 19:22, 3 June 2014 (UTC)

doi:10.4236/fns.2013.41005 is a weak primary source that does not demonstrate whether exclusion of further foods actually improved the symptoms. There is a real risk of losing out on important micronutrients and I cannot support a significant section on something dubious like this. Many times, contamination is the real issue.

I added a link from "vitamin deficiencies" to Avitaminosis. If that's not an appropriate link, then could someone suggest a different one? Rissa, copy editor (talk) 19:04, 25 June 2014 (UTC)

Inaccurate schematic of mucosal immunopathology[edit]

The schematic of mucosal immunopathology shows the crypts of Lieberkühn inaccurately. In the current schematic, they are shown running perpendicular under the villi wherein reality they are positioned at the base of villi in parallel shafts. [1][2]

It's an otherwise nice diagram of the Marsh score, but it needs to be either corrected to show the crypts properly or else removed. AcrossThePond (talk) 16:16, 2 July 2014 (UTC)

WikipedianProlific, the creator of the image, is not active anymore. Do you think you could modify the image yourself and upload a corrected version, AcrossThePond? JFW | T@lk 20:10, 2 July 2014 (UTC)

The British Society of Gastroenterology has (finally!) issued a consensus guideline. doi:10.1136/gutjnl-2013-306578. The article will require updating. JFW | T@lk 14:56, 8 July 2014 (UTC)
