Helminthic therapy[edit]

I have significantly shortened the section on helminthic therapy. This is still in its experimental stages, and Wikipedia does not need to tell the public how a German company is trying to market this. When it hits the shelves, we'll see.

I have also replaced the news links with an actual scientific report in a peer-reviewed journal. The BBC link quoted the New Scientist, and the latter got its information from the article. This is much more direct. JFW | T@lk 23:17, 27 Nov 2004 (UTC)

Please note the link is broken for the scientific report (reference #19). This should be fixed. — Preceding unsigned comment added by 71.7.239.165 (talk) 13:27, 2 January 2012 (UTC)

Life events[edit]

Rollback feature[edit]

I have been reverting a vandal, but I made a mistake the first time and I think I corrected it the second time. Just started using this so please if I still made any mistakes please bring it to my attentions and I will fix it or always feel free to fix anything I should do. Thank you, --CrohnieGalTalk 11:39, 25 April 2008 (UTC)

External links[edit]

I've pruned the external links section. I removed:

  • a dead link (no content),
  • a blog,
  • a link to an organization that provides face-to-face meetings in two cities, and
  • an online support group.

The first three are pretty obvious to most people: for example, Wikipedia is a worldwide encyclopedia, and something that happens half a world a way does you no good. The last one sometimes surprises people, so let me explain. Wikipedia's external links policy and the specific guidelines for medicine-related articles do not generally permit the inclusion of external links to non-encyclopedic material, particularly including internet chat boards and e-mail discussion groups. Here's some specific information from the guidelines:

  • This page, which applies to all articles in the entire encyclopedia, says that links "to social networking sites (such as MySpace or Fan sites), discussion forums/groups (such as Yahoo! Groups), USENET newsgroups or e-mail lists" are to be avoided.
  • This page deprecates ""helpful" external links, such as forums, self-help groups and local charities."
  • This medical-specific page reinforces the pan-Wiki rules, with a note that "All links must meet Wikipedia's external links guidelines, which in particular exclude discussion forums."

Wikipedia is an encyclopedia, and while it may occasionally be useful to patients or their families, it is not a web directory.  Please do not re-insert links that do not conform to the standard rules.  Any editor, BTW, is welcome to read all of the rules and perform another "audit" in the remaining links.  Thanks, WhatamIdoing (talk) 03:36, 28 April 2008 (UTC)

Pred of death[edit]

HLA - B27[edit]

add info about HLA-B27 please! —Preceding unsigned comment added by 128.125.28.127 (talk) 01:39, 1 June 2008 (UTC)

Thrombosis[edit]

Risk of thrombosis increased, especially during flare. I can hear a trial approaching, especially with one of the oral antithrombotics. In fact, perhaps this might also show a disease modifying effect! doi:10.1016/S0140-6736(09)61963-2 JFW | T@lk 10:04, 21 February 2010 (UTC)

What kind of inflammatory bowel disease is this?[edit]

Before any reinsertion, I think it needs to be specified what kind of inflammatory bowel disease (if even IBD) is referred to in the following study, since it appears to consist of multiple types with different pathogenesis. Mikael Häggström (talk) 16:20, 25 October 2010 (UTC)

Research[1] has shown that IL-23 is overexpressed in tissues taken from mouse models of IBD. The group showed that knocking out IL-23 (heterodimer of IL-12p40 and IL-23p19) sharply reduced inflammation of the bowel, both in terms of cells and proinflammatory cytokine production. Also, they found that a novel group of CD4+ T lymphocytes, Th17 T cells, are highly unregulated in bowels of diseased mice. Taken together, the group shows that IL-23 but not IL-12 (a heterodimer of IL-12p40 and IL-12p35) drives innate and T cell mediated intestinal inflammation.

Evolutionary Considerations[edit]

Prototype to material that should be considered when discussing causes of IBD

The low incidence of pathogens within modern societies are thought to have contributed to Inflammatory Bowel Disease vulnerability[1] . This has been known as the Hygiene Hypothesis[1] . Humanity has been exposed to a wide range of bacteria and viruses with the practice of agriculture in the Neolithic Revolution[1] . This was due to an increase in population density and a sedentary lifestyle that accompanied agricultural practice[1] . In the post Neolithic Revolution, humans adapted to the high rate of pathogens through developing a more active immune system[1] . In the modern society, improved sanitation and medicine has lowered pathogen exposure[1] . This leads to an evolutionary mismatch between adaptation and environment where the low pathogen exposure increases susceptibility to Inflammatory Bowel Disease[1] . This is a result of an inappropriate response from the immune system that has not been exposed to many pathogens[1] . Several lines of evidence have proven supportive of this hypothesis[1] . Helminthic infection, which was common in a pre-modern setting, is shown to modulate a strong Th2 response[1]. The increase in Th2 decreases the Th1 response which is associated with auto-immune and Crohn's Disease. Patients with IBD are shown to have lower prevalence of Helicobacter pylori, common in third world countries, to matched controls and disease controls.[1] This observation suggests a protective role of H. pylori in the development of IBD[1] . Taken together, these suggest that the active immune system is mismatched in the modern, low pathogen setting and may be a reason for vulnerability to IBD.[1]

I am unable to glean useful text from the content above, but have copied it to User:LiZhang1312/sandbox so the original editor can continue work there. SandyGeorgia (Talk) 14:47, 24 October 2013 (UTC)
One needs to be very careful about WP:RECENTISM and WP:MEDRS here. "New research" might not yet be suitable for inclusion into an encyclopedia article. Artices and studies on the evolutionary aspects of disease are almost without exception highly speculative, and of course cannot be confirmed experimentally. JFW | T@lk 11:47, 25 October 2013 (UTC)

Proposal ?[edit]

This might represent a copyedited version of the proposal above. It lacks wikilinking, and there are undefined terms. It also lacks analysis of why this hypothesis has not gained wide traction, and it is based entirely on one source which is a review limited specifically to one theory, not a broad overview of IBD (in other words, WP:UNDUE missing-- what weight should be assigned to this theory, if any). If something along these lines were to be included, it would not be under "Evolutionary considerations", it would be under "Causes" (See WP:MEDMOS). Perhaps User:Jfdwolff will have a look to opine on the due weight aspects, as well as the proposed text. SandyGeorgia (Talk) 17:19, 11 November 2013 (UTC)

The "Hygiene hypotheis" says that low incidence of pathogens within modern societies may have contributed to IBD vulnerability.[1] Due to an increase in population density and a sedentary lifestyle that accompanied agricultural practice, humanity was exposed to a wide range of bacteria and viruses.[1] In the post-Neolithic Revolution, humans adapted to the high rate of pathogens by developing a more active immune system; in modern society, improved sanitation and medicine has lowered pathogen exposure, leading to an evolutionary mismatch between adaptation and environment where the low pathogen exposure increases susceptibility to IBD as a result of an inappropriate immune response.[1] Several lines of evidence have proven supportive of this hypothesis:[1]

  • Helminthic infection, which was common in a pre-modern setting, is shown to modulate a strong Th2 response.[1]
  • The increase in Th2 decreases the Th1 response which is associated with auto-immune and Crohn's Disease. Patients with IBD are shown to have lower prevalence of Helicobacter pylori, common in third world countries, to matched controls and disease controls.[1] This observation suggests a protective role of H. pylori in the development of IBD.[1]

LiZhang1312, by altering your previous post here on talk, you make it harder for other editors to discuss your proposed text. You might instead say that you have proposed text in your sandbox, link to your sandbox, and ask for commentary there. SandyGeorgia (Talk) 17:22, 11 November 2013 (UTC)

It is not a secret that WJG is a journal that is known for doubtful editorial practices. The above version attempts to summarise the hygiene hypothesis and to cite it to Koloski et al. Nowhere in Koloski et al is there any mention of a Neolithic Revolution. The content is very much not ready for inclusion. JFW | T@lk 20:55, 12 November 2013 (UTC)

Causes - 'Concentrated milk fats' ?[edit]

Anybody know what that's supposed to mean? Isn't milk fat just butter? How can you concentrate it? Looks like anti processed food POV pushing to me. --Ef80 (talk) 22:09, 19 December 2013 (UTC)

The intent may be to include both cheese and butter.187.210.137.17 (talk) 17:17, 20 December 2013 (UTC)

"medicine" doesn't need a link[edit]

1st and most important sentence in the article, 2nd word "medicine" links to the wikipedia article on "medicine" which I think is ridiculous. As if "inflammatory bowel disease" might also apply to some other area, such as astronomy or economics.Jonny Quick (talk) 18:58, 27 July 2014 (UTC)
