Talk:Inflammation

Exercise and Inflammation

I think this section is far too extensive for this article. Other specific, much more classical, examples of inflammation are not discussed here. I think it should be moved to another article, such as Muscle or Exercise. Ehudzel (talk) 15:30, 6 May 2011 (UTC)

General Concerns and Suggestions

This article needs to be reworked in a lot of different ways including conceptually. The basic problem is that there is no principled distinction between older/classic regional inflammatory concepts ,which this piece presents reasonably well, and newer and equally important concepts about chronic or systemic inflammation, particularly the destructive disinhibition of inflammation in aging (barely mentioned as an afterthought in relationship to diabetes towards the end of the article). Specifically, one might consult the work of E Sikora, B Aggerwal, S Bengmark, and the classic paper on this by Franceschi C, Bonafe M, Valensin S, Olivieri F, De Luca M, Ottaviani E, De Benedictis G: Inflamm-aging. An evolutionary perspective on immunosenescence. Ann N Y Acad Sci 2000, 908:244-254. This work suggests that aging itself may be both a consequence as well as a driver for progressive auto-inflammatory damage. These concepts have to be seen as having a huge influence on how we understand aging itself and how we might protect ourselves from the accelerated aging associated with the Western lifestyle and diet, which are strongly pro-inflammatory in a number of ways. It's a shame that despite previous and explicit suggestions about this, the author has chosen to ignore this entire realm of literature completely. for this reason I am spelling out my differences with this whole approach more explicitly in this extended comment.

First of all, the evidence is now virtually overwhelming that every disease of aging (Alzheimer's disease, cancer, heart disease, diabetes, arthritis, etc. etc.) is associated with long-term damage done by our own immune systems. For example, there is now solid evidence that the transition from mild cognitive impairment to dementia in patients with Alzheimer's disease is associated with up regulation of various cytokine systems, although it is not so clear what is driving this. There is also enormous evidence that cancer is associated with long-term inflammatory damage to various cell populations, and that upregulation of inflammatory pathways particularly the transcription factor nuclear factor kappa b, is critical to cancer pathogenesis. Heart disease is clearly associated with inflammatory processes on the arterial wall (in the context of oxidized lipids) enabling plaque formation. Diabetes particularly type II diabetes also has a close relationship with this pro-inflammatory transcription factor being upregulated.

I don't think that any reasonable treatment of inflammation can fail to emphasize all these basic linkages and still claim to be remotely comprehensive. Additionally, any treatment of the subject would have to at least link to a page on cytokines, which appear to come in both anti-and pro-inflammatory forms. The treatment here also fails to emphasize the relationship between stress and inflammation, between sleep deprivation and inflammation, and between depression and inflammation, as there is increasing evidence that depression is in part mediated by elevated cytokines. Additionally, treatment fails to mention numerous diseases that may involve dysregulation of inflammatory pathways and cytokines including particularly IBS, fibromyalgia, and chronic fatigue syndrome. There is also no principled discussion of anti-inflammatory drugs or anti-inflammatory foods, and there is more and more evidence that omega-3 supplementation is valuable because it reduces systemic inflammation (the omega-3 pathway competes with the omega six pathway for the same enzymes, and the omega six pathway promotes prostaglandins and other pro-inflammatory molecules.) Clearly there are a lot of things that could be improved here, but I would start with an emphasis on how the immune system cuts both ways, it clearly is essential for our survival, but its chronic overactivity may contribute hugely to diseases of aging and even to aging itself. This potentially makes the topic a lot richer and a lot more interesting.

Indeed it looks like one of the critical ways to prevent many of the diseases of aging is to keep the innate immune system under control by ensuring a good nights sleep, regular exercise, and an anti-inflammatory diet (decent amounts of fruits and vegetables and a good amount of omega-3, with not too much omega 6, or processed carbohydrates).

The role of the nervous system in inflammation isn't mentioned. Chronic inflammation has been experimental shown to be mediated by the nervous system in A.D. Speransky's Basis for the Theeory of Medicine 1943. This is obviously the reason that stress and other nervous systems ailments have an effect as well as reason stress reducing changes in life style can have positive effects. Inflammation can be a local vascular response, a more distributed nervous response or typically combination often with complex interactions between the two.

Fifth cardinal sign

In the textbook Pathophysiology: Concepts of altered health states (7th edition) by Porth it says that the 5th cardinal sign "loss of function" was added by Galen in the 2nd century AD, not in the 19th century by Ahmed Abou Samra. Google searches containing one name and the term "loss of function" or the latin "functio laesa" seem to indicate that porth was correct. It also says that Celsus termed the first four signs in the 1st century AD if that helps anyone at all.58.170.163.218 (talk) 12:21, 9 April 2008 (UTC) Systemic inflammation and overeating

Hyperglycemia induces IL-6 production from endothelial cells and macrophages.[35] Meals high in saturated fat, as well as meals high in calories irrespective of macronutrient composition, have also been associated with increases in inflammatory markers.[36][37] While the inflammatory responses are acute and arise in response to overeating, the response may become chronic if the overeating is chronic.

Anti-inflammatory foods

I am interested to know what people think about the idea of Anti-Inflammatory foods. It seems to be a topic that is coming up more and more (see: Hello Anti-inflammatory foods, List of Anti-inflammatory foods). Is there a good scientific basis for this?

I was also curious about this. There doesn't seem to be any scientific basis for what the woman is saying in the referenced article. It's unfortunately that such an important subject like nutrition is flooded with all sorts of cult theories. DonPMitchell 19:53, 29 April 2007 (UTC)

Maybe it is flooded with all sorts of cult theories because the entire subject is given such short thrift in medical schools (and even less with the general public) thus most people, along with most conventional physicians, don't know hardly anything about it and just assume that it doesn't really make that much difference. Then, sometimes, when some people get ill, out of desperation, they "think outside the box" and try some of the "cult" methods and find that they seem to work, and the theories make sense (are rational), thus reject the orthodoxy and conventional wisdom that poo-poos all of it. Shanoman (talk) 23:00, 29 May 2009 (UTC)

Good Questions and Points. There is actually quite a bit of literature about anti-inflammatory foods. See for example virtually anything written by Aggarwal ( go to Medline and enter his name and you will get literally 100 pieces). In any case, the anti-inflammatory food business probably breaks down into three large topics (and there's probably more complexity to it than we currently understand). One large topic is the omega-3/omega-6 ratio, which as I mentioned above is a critical modulator of the inflammatory equation - this is where food technology has really screwed things up. For example, if you eat beef that has been fed corn, instead of its native grass diet, you completely alter the omega-3/omega six ratio and wipe out the omega-3 components virtually completely. However, bison or cows eating their native diet show a decent omega-3/omega six ratio. No one is exactly sure what this ratio should be, but the evidence argues that our ancestors had a ratio in their diets of between 1/2 to 1/4. The evidence is the current American diet is somewhere between 1/15 to 1/45. This is a hugely pro-inflammatory shift, given that the omega six fraction (which is restrained and competes with the omega-3 fraction for conversion enzymes) is the primary pathway into prostaglandins. This is why eating fish particularly fish high in omega-3 or taking fish oil supplements is really valuable (although people typically underdose this, and think that fish oil is the same as omega-3 when most fish oil preparations are roughly 30% of omega-3.) So that's one aspect of it.

The second aspect relates to phytochemicals (substances in plants - fruits and veggies) - that alter the inflammatory equation as well. Without going into too much detail, this is multifactorial, and there are lots of issues. But one interesting one is that almost all fruits and veggies in one way or another inhibit a transcription factor known as NF-kappa B. This is the transcription factor (and these control whole families of genes, like a conductor in front of the orchestra) most intimately linked to the upregulation of inflammation. Also, various polyphenols (simplistically labeled as antioxidants) found in virtually all fruits and veggies, affect classic inflammatory pathways like COX, LOX, and prostaglandins.

A third aspect is related to dietary fiber content. Fiber appears to down-regulate the inflammatory equation, perhaps because systemic controls on inflammation are intimately linked to the amount of GI inflammation, but this is not clear (at least to me). So eating lots of fiber is also anti-inflammatory.

The long and the short of it is that the Western lifestyle (poor sleep, sedentary lifestyle, poor omega3 intake, tons of omega 6 foods and processed food while not enough plants and protective phytochemicals, lots of stress and social isolation, is a one way ticket into inflammatory upregulation, with accelerated aging and vulnerability to the diseases of aging as a direct consequence. This brief summary doesn't do justice to the relationships between inflammation, oxidative stress, insulin resistance, and glycation of proteins (the primary biological factors involved in aging), but suffice it to say, the relationships are reciprocal. Reducing inflammation also reduces oxidative stress, and insulin resistance.

question

WHICH CHEMICAL CAUSE INFLAMMATION?

Hope this will answer your question: NSAIDs are COX inhibitors that inhibit the enzyme cyclooxygenase from transforming arachidonic acid (a derivative of cell membrane phospholipids) to prostaglandins. The prostaglandin family contributes to an inflammatory response mainly by increasing vasodilatation and vascular permeability. If the formation of the different arachidonic acid metabolites in the prostaglandin family is inhibited, some of the cardinal signs of inflammation might be decreased. Use of COX inhibitors, such as aspirin, will also decrease the ability of platelets to adhese and form a primary clot (see hemostasis and coagulation for more info on the formation of a blood clot) This is because COX inhibitors inhibit the formation of thromboxane (TXA₂) in platelets. When used excessively, most NSAIDs might predispose to gastric ulceration by inhibiting COX-1. Some of the prostaglandins produced in the cyclooxygenase pathway are essencial for the protection against acid induced damage of the gastric mucosa and by inhibiting COX-1, the production of these metabolites is decreased. Recently, selective COX-2 inhibitors have been developped, obliterating the harmful effects of the COX-1 inhibitors on the gastric mucosa. However recent studies have shown that these drugs might lead to acute coronary artery disease.

extremely graphic images

So, here is the real issue: a lay reader is not going to be expecting this page to include depictions of the pathology anywhere near that graphic. I'm not sure why wikipedia doesn't have a standardized graphic-images warning, because this seems to be a textbook case where one would be important - at least for managing expectations and preparing oneself. Most viewers of this page will NOT be specialists. Many will be newly diagnosed with an inflammatory condition and looking for help. Clearly the images are important and should remain, but I found the images traumatic to view and would have been prepared for them with a simple warning.

Need Help

I have started a new page called inflammatory diseases of unknown etiology and would like some help answering these questions: What are the inflammatory diseases of unknown etiology? How many of them are there? What are the most common inflammatory diseases of unknown etiology? What kind of inflammation is associated with inflammatory diseases of unknown etiology? And how many kinds of inflammation patterns are there in inflammatory diseases of unknown etiology? If anyone has the time to contribute it would be appreciated.

treatment options?

Shouldn't this page include a section on treatment options to be of service to those who suffer from chronic inflammatory conditions? FQ1513 (talk) 23:25, 22 December 2007 (UTC)

Not necessarily. Inflammation is a perfectly normal process. It doesn't necessarily need to be treated at all, and even when it does, the best treatment depends on the actual cause. A treatment section would basically boil down to "Inflammation normally goes away by itself, and when it doesn't, then you need to figure out the cause and treat the cause." A list of all possible treatments for all kinds of inflammation would be a mile long and basically useless. WhatamIdoing (talk) 19:45, 23 January 2008 (UTC)

muscle strain inflammation

I was given COX-2 inhibitors to get rid of a painful inflammation in my hand that persist for several weeks (I lift weights, was on a month off, pulled a muscle when I came back).

I was surprised to find that muscle strain is not listed as causing inflammation. Indeed, the article implies such inflammation is either an external entity (virus) or autoimmune problem. From other inet sources I've learned that pulled muscles have broken fiber, leading to inflammation which is mostly self-sustained (in a way, an autoimmune problem) hence COX-2 inhibitors treatment resolve the issue.

Agreed. While the cardinal signs of inflammation are mediated through changes in the vascular tissue (vasodilation, endothelial permeability), conceptually, contemporary understanding of inflammation is much broader than this and includes at least the immune system as well. —Preceding unsigned comment added by Gregnz (talk • contribs) 21:51, 25 November 2009 (UTC)

Pictures, Particularly the Greeting Photo

Some of the previous posters are correct. Particularly, the first picture detracts from the readability/digestibility of the article. If you (the reader) are in favor of this picture, please try not to take offense at the following remarks, but please try to look at the criticism objectively. The picture needs to be more "diplomatic", and not offensive to 30 to 50 to who-knows-what percentage of the readers. Just because the picture-insert-er and this article's favorite moderators have developed a stomach for such a picture (with extra-articular information such as necrotic tissue and puss in the middle) does not mean that they should show their stamina off to the rest of the population. Again, if you (the reader) are one such as this, please, try not to take offense at the anti-current-picture camp's remarks, but objectively look at the picture, the article's title, and what others have said before me.

This site is not intended to be a comprehensive, professional, medical resource per se, but is a reference for the general population of the world. It should not be forcing it's subscribers to high-tolerance-necessary, professional, overkill photos, just because someone found or created what was to them "the perfect photo" for what belongs to a more specialized topic than "Inflammation", or to a professional medical reference where the subscribers are expected -- by the nature of their career -- to have developed the tolerance/stomach for such images.

In summary, the previous objectors have a point, and it ought not be ignored only because of their potential lack of credentials. At least, the more offensive pictures should be found at the bottom of the article, if not instead as part of a more acute or specialized article on the subject to which "black rings of necrotic tissue surrounding pus" might more readily pertain, particularly as a greeting photo. It can be assumed that when the general population of the world goes looking for an article on "inflammation", they are likely not thinking of "black rings of necrotic tissue, surrounding central areas of pus", both of which are not even a component of "Inflammation". The picture that should be used as the greeting picture, should be one that has as it's prominent feature, the five "cardinal signs" of inflammation (necrotic tissue and pus "not" being members of this list). The current greeting picture clearly should be changed or removed.

Draft section, with footnotes - Neurogenic inflammation

Neurogenic inflammation is inflammation arising from the local release from afferent neurons of inflammatory mediators such as Substance P and Calcitonin Gene-Related Peptide (CGRP).

This process appears to play an important role in the pathogenesis of numerous diseases including psoriasis, asthma, fibromyalgia, eczema, rosacea, dystonia, multiple chemical sensitivity, and migraine.

In migraine, stimulation of the trigeminal nerve causes neurogenic inflammation via release of neuropeptides including Substance P, nitric oxide, vasoactive intestinal polypeptide, 5-HT, Neurokinin A and CGRP.

Treatment

The treatment of migraine with CGRP blockers show promise. In early trials, the first oral nonpeptide CGRP antagonist, MK-0974 (Telcagepant), was shown effective in the treatment of migraine attacks, but elevated liver enzymes in two participants were found. Other therapies and other links in the neurogenic inflammatory pathway for interruption of disease is under study, including migraine therapies.

Noting that botulinum toxin has been shown to have an effect on inhibiting neurogenic inflammation, and evidence suggesting the role of neurogenic inflammation in the pathogenesis of psoriasis, the University of Minnesota has begun a clinical trial to follow up on the observation that dystonia patients treated with botulinum toxin had dramatic improvement in psoriasis symptoms.

Astelin (Azelastine) "is indicated for symptomatic treatment of vasomotor rhinitis including rhinorrhea, nasal congestion, and post nasal drip in adults and children 12 years of age and older."

Statins may be useful for treating diseases presenting with predominant neurogenic inflammation.

Depression

Two claims are made: (1) that "negative cognition" causes inflammation and (2) that inflammation causes depression. While the latter is plausible (if not particularly interesting), the former is surprising and calls out for strong evidence. The citation given is a psychology paper about social prejudice and depression, and inflammation is not mentioned in the abstract. Even if the paper does claim thoughts cause inflammation, establishing this seems well beyond its scope. 216.239.45.130 (talk) 00:14, 9 July 2013 (UTC)

As someone who has both, I found the later particularly interesting! But to add to this area, I have found a paper named "From stress to inflammation and major depressive disorder: a social signal transduction theory of depression" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4006295/ - which appears to support the whole statement. I haven't read the whole article yet, but the sentence:

"Central to this social signal transduction theory of depression is the hypothesis that experiences of social threat and adversity up-regulate components of the immune system involved in inflammation"

in the abstract supports, if not the 1st claim directly, at least a similar statement - that stress has been shown to increase inflamation. It is further supported by the passage:

"A large number of naturalistic and laboratory-based studies have examined whether stress is associated with inflammation. As we review below, these studies strongly support such an association. Moreover, consistent with the CTRA model presented earlier (see Figure 1) and with the data just described linking social rejection and depression, associations between stress and inflammation appear to be particularly strong for stressors that indicate the presence of possible physical or social threat. To examine these effects, we first review studies showing that early life stress, adulthood life stress, and laboratory-based social stressors are associated with increased inflammatory activity. Then, we discuss neural, genetic, and genomic mechanisms that may be responsible for converting experiences of social stress into inflammation."
