The Chlamydia Pneumoniae Handbook

Purposes of this Handbook

This "Handbook" is an attempt to organize and pull together information on Chlamydia pneumoniae, it's impact on human diseasesi, and it's treatment via combined antibiotic protocolsi into a more easily accessible, organized and up to date format. Some of the material has already been posted on www.cpnhelp.org website and is simply linked here in a more organized way. Some of the material in this handbook is new and represents the most current, state of the art information on Cpn, CAPi, and the various supplementsi which have been found helpful in clinical experience. We will endeavor to update and expand the Cpn Handbook as new information becomes available.

Printing the Handbook

Consider printing out the whole Handbook for yourself or your doctor, here's a trick:

  1. At the bottom of this page of the Cpn Handbook click the "print friendly" link. You should get a document of 50+ pages to appear.
  2. You can directly print or save as pdf file and print from your own computer.
  3. The only thing which doesn't come out right is the Table of Contents. Trick: Go to that page from the Handbook left sidebar link (you only see this once the Handbook is selected) and then at the bottom go to the "print friendly" link (not the "alternative" line) and it should appear.
  4. Print it out or save as pdf file and add to your handbook copies.

 Of course, you can print out individual selections of the Handbook by going to that specific page and using the 'print friendly' link at the bottom of the page.

Date your copies, and check back to make sure you have the most current edition as we are adding to it and editing frequently. 

Under Construction:

This is the starting page for a collaborative effort to pull together the information gathered about Cpn: research, it's implication in various diseases, the arguments about it's legitimacy, its treatment via combination antibiotic protocol, and frequently asked questions about all this. Ahem! Quite a run-on sentence.

The handbook will be organized from existing pages, as well as from new and updated material. It's a work in progress so... stay tuned!

Introduction to Chlamydia Pneumoniae (Cpn)

Introduction to Chlamydia Pneumoniae (Cpni)

Chlamydia Pneumoniae (Cpn) is a tiny bacterium which is most often noted for causing a form of pneumonia. Up until the 1970's it was not even isolated and was mistaken for a virus (its discovery is an interesting story and can be found here: http://www.washington.edu/research/pathbreakers/1989a.html).

It was not until 1989 that J. Thomas Grayston and his associates named it as a separate species of the Chlamydiae. Cpn is very difficult to culture and so, without modern lab techniques, also to study. It is an intracellulari bacterium, which means that it invades the body cells, and it is an obligate parasite, which means that it cannot supply it's own energy source and so takes over the energy machinery of the body cells it invades, depleting them and leaving the host cell less functional.

 

Cpn has been implicated in a wide variety of diseasesi and is seen by some researchers as a causal factor in particular disease such as  Multiple sclerosis , Chronic fatigue , Asthma , Rheumatoid Arthritis (RA) , Fibromyalgia , Chronic refractory sinusitis , Cardiac disease , Interstitial cystitis  , Prostatitis, Alzheimer's disease Crohn's disease , Inflammatory bowel diseasei and others

Below: a diagram of the Cpn life cycle from http://herkules.oulu.fi/isbn9514269853/html/x467.html (which is also an excellent text on Cpn biology and treatment).

 Cpn Life Cycle

 

What makes Chlamydia Pneumoniae (Cpn) especially troublesome?

    * While it may start as a respiratory infection, Cpn can be carried to other parts of the body and infect many other tissues, including nerve tissue, the brain, muscles, kidneys, liver, prostate, the lining of blood vessels and even your immune cells (macrophages and monocytes). Thus a wide array of problems can be caused by this single bug.
    * The standard single antibiotic courses (two weeks monotherapy) which doctors typically used only kill Cpn in one of its three life phases, leaving other live forms of Cpn bacteria which are in other stages to renew infection. This is what creates persistencei and relapse in Cpn and it's related diseases.
    * Cpn contains at least two endotoxinsi (toxic chemicals) which cause tissue damage and inflammationi, chronic immune activation and toxic load in your body. Killing the Cpn releases large amounts of these endotoxins, called a die-off reaction, making treatment uncomfortable.
    * Cpn infects inside your cells and parasitically steals energy from your own body cells in order to replicate. The cells and organs it effects become less and less functional over time as Cpn load increases in them.
    * The only way to cure it is to take a combination of antibioticsi (see Combination Antibiotic Protocols), to kill it in all of its life phases so nothing is left behind to re-infect. This can take a long time depending on the load of Cpn in your system, the organs infected and other variables. Typical courses of 1-3 years are not unusual.

Cpn Simple the simplest summary of we could think of, and might be a good beginning for those of us a bit brain fogged or just plain overwhelmed by the whole thing? 

Advice to Non-Medical Newcomers

Why are you here?  The reason is the same for all of us.  Either you or someone you care for is sick, so you're looking for something, anything to help.  Maybe it's MSi, CFSi, ME, FM, Lupus, Alzheimer's, unrelenting fatigue, pain and inflammationi, or something else.  You might  be desperate because you're up against a wall built of words like incurable, untreatable, and of unknown origin.  Perhaps a cutting-edge medication has been tried and failed.  With the media full of news about medical breakthroughs, you're frustrated that a meaningful treatment has not been found for your illness.  You're thinking that surely the answer lies somewhere out there in the vast body of knowledge that makes up modern medicine...someone just hasn't connected the dots yet.  You surf the internet and find websites offering support and education on the illness. You read articles about research and new treatments.  Much of it is written in medical-ese, and you may feel overwhelmed, even handicapped in your ability to milk the meaning out of the information you find.

I am a caregiver and care advocate for my husband who has a degenerative illness.  I have no medical background and I'm cyber-challenged.  If, like me, you're stubborn enough to keep struggling with all those research and treatment articles, and if you can make any sense out of them, a bigger picture emerges.  When you step back to assess the various bits of information collectively, you will find a gaping hole.  Something huge is missing.  The problem is that most of the current research and emerging treatments focus on "tinkering" with the disease process, not on addressing the root cause of the disease.  Why is that?

Things they forgot:  Entertain some what ifs with me.  What if research into the disease had been underway for several decades?  What if, in those early days, research efforts were concentrated on finding a microbe as the villain?  After all, the immunei systems of the people afflicted with the disease seemed to be attacking something that shouldn't have been there.  What if, after no infectious agent was found, the research community embraced the theory that the body sometimes goes nuts and attacks itself via a defective immune system?  What if this interesting autoimmune concept led researchers into some limited success in developing drugs that "tinker" with the immune system to some benefit for some of the afflicted some of the time?  Limited success is better than no success.  What if herd-mentality caused a stampede of researchers in one direction?  What if, in the meantime, there had been advances in microscopy and lab techniques that might have enabled those early researchers to find what they had been looking for?  What if the majority of the research/medical community had somehow lost track that the model of autoimmunityi was an unproven theory, and they had comfortably incorporated it into their thinking and efforts as though it were a given fact?  What if new technology applied to old ideas could result in the hope of treating the disease at its core rather than just "tinkering" with the disease process?

My husband's illness has been rubber-stamped as autoimmune.  Like you, I was searching, and like you, I am a relative newcomer to this website.  Most of the material on cpnhelp.org is very understandable, but you will eventually run into unfamiliar medical terms and processes.  Advice from other users, resource tips gleaned from their blogs, and my own experience have helped me develop a system for digesting the cpnhelp.org material and for understanding the medical-ese I encounter elsewhere on the internet as I investigate my husband's illness.  I'm offering you a shortcut.  Please let me help you in your quest to get the most out of this website, lits linked websites, other websites you are already visiting, and those you will visit in the future (especially those research articles).

Cpn Simple

 

Cpni Simple- The shortest explanation we could think of!

  • Cpn has been clearly proven to have persistencei in the body despite “standard” antibiotic treatment (two weeks of a single antibiotic).
  • Cpn has been implicated in a wide variety of diseasesi (see bottom of this page).
  • Blood tests and cultures are not reliable indicators of whether Cpn is part of your disease.
  • If you have any of the diseases in which Cpn has been implicated, it may be worth trying an “empirical” (based on symptoms alone) combination antibiotic protocol (Link).
  • Most doctors are not familiar with this, and you will have to present a rational and evidence based case to them for prescription of the appropriate antibioticsi through information such as on this site.
  • Is this right for you? 

    Four indicators can be used to help you determine if an empirical test of the full combination antibiotic protocol is useful for you. You should be on it for for a minimum of 6 months to a year. The first three suggest that you have Cpn and you should continue this treatment.
    1. You experience distinct reactions to the antibiotics indicative of Cpn die-off (see Reactions to Treatment link).
    2. You have improvement of disease symptoms.
    3. You have noticeable halting of symptom progression.
    4. Nothing at all and decide this isn’t for you.

    Killing Cpn In Different Phases

    Diagram from David Wheldoni (http://www.davidwheldon.co.uk/killing.jpg) used by permission. 

    Phases of the Cpn bacteria and what agents effect those phases:

    EB’s- Elementary Body What are they? EB’s are spore-like forms which are infectious and metabolize minimally (aren’t using nutrients, replicating, exchanging with the environment, etc.). They are tough, tiny and reside in the intercellular tissues (outside of actual body cells). What do they do? EB’s attach to your body’s cells and invade them. Since there can be more EB’s than can get into cells, EB’s build up in local tissues causing inflammationi and immunei response.

    What kills them? They are killed by amoxicillini, which is transformed to penicilamine in your own body, and destroys the bonds which hold the EB cell wall together. An amino acid NACi (N-acetyl cysteine) also is used for this purpose. What happens? When you kill them, they release toxin into the tissues in which they have built up, and you get inflammation and pain there, which can last for days or weeks afterwards before you feel relief of symptoms. Most people taking NAC report a period of flu-like feeling of malaise, achyness, nunning nose, perhaps coughling.

    RB's- Reticulate Body What are they? Once an EB enters a host cell it transforms into a form which can replicate new EB'si which is called a Reticulate Body or RB. The RB has no energy source of it's own for this, so it must steal energy (ATP) from the host cell, leaving the host cell weakened and less functional. The RB also inhibits the natural cell deathi of the host cell so that it can survive while it replicates. After the production of many new EB's the host cell bursts and dies, spreading the infectious new EB's into the surrounding tissue.RB's are inhibited in replicating by various antibiotics such as doxycycline, azithromycin, roxythromycin and others, and subject to this will convert into the Cryptic (and nonreplicating) form where they can be killed by metronidazolei. RB's are prevented from forming by rifamcini.

    Cryptic formi
    What are they? When RB’s face an environment which threatens their survival inside a cell (lack of food, antibiotic attack, etc) they can transform into a “Cryptic” form which stays inside the cell, but is in hibernation, so to speak. What do they do? In this form it is not vulnerable to regular antibiotics and can reside there until conditions change, then become an RB again and start to replicate and reinfect with EB’s. What kills them? Flagyl (metronidazole) or Tinactini (tinidazole) are used to kill the cryptic forms of Cpn. Nitrofurantoin, an old urinary tract infection drug, also has antichalmydial effect in this phase. These drugs can be hard to tolerate for various reasons, and so are commonly “pulsed” by taking a course for 5 days every 3-4 weeks, rather than taken continuously. Some protocolsi may eventually have one of these drugs taken continuously for some period as the patient can tolerate. Patients may experience fatigue, nausea, bowel upset, deep joint achyness and muscle pain as the cryptic orgnanisms are killed and the immune system engages in clean up.


    Much of the discomfort from treating Cpn is a combination of the organism's endotxin itself, and the inflammation caused by your own immune system (cytokinei) reactions to that.

    SUMMARY

    Amoxicillan and NAC kills the infectious spore-like EB forms which build up in the tissues.

    Rifamcin kills EB’s transforming to RB’s in a vulnerable enzyme transformation phase.

    Doxycycline and either Rozithromycin or Azithromycin, are used in combination to interfere with the RB’s ability to replicate. Two are used which work on different proteins to minimize creating resistance.

    Supplementsi are recommended to help counter the impact of Cpn on the body, and of the inflammatory effect of the die off during treatment.

    Treatment can take months to years to completely eradicate Cpn from the body.

    What diseases has it been implicated in?
  • Multiple sclerosis
  • Chronic fatigue
  • Asthma
  • Arthritis
  • Fibromyalgia
  • Chronic refractory sinusitis
  • Cardiac disease
  • Interstitial cystitis 
  • Prostatitis
  • Crohn's disease
  • Inflammatory bowel diseasei
  • Alzheimer's disease
  • Additionally: chronic obstructive pulmonary disease, uveitis, optic neuritis, radiculitis, nerve deafness, transverse myelitis, sarcoid, myocarditis, pericarditis, culture-negative endocarditis, atheromatous arterial disease, aneurysm, giant-cell (temporal) arteritis, polyarteritis nodosa, Wegener's granuloma, primary sclerosing cholangitis, reactive arthritis, Reiter's syndrome, Behcet's disease, cutaneous vasculitides including pyoderma gangrenosa. Wheldon adds: "Conditions which may suggest the possibility of flare-ups of chronic Chlamydia pneumoniae infection deserving serological investigation include the following — a multiplicity being more strongly suggestive: recurrent sinusitis, recurrent chest infectionsi, chronic fatigue (especially if following a respiratory infection), focal neurological deficits, myalgia, muscle fasciculation's, recurrent episodes of bronchospasm, unexplained pleuritic pain, angina, recurrent arthralgia, unexplained recurrent abdominal pain, unexplained menorrhagia, recurrent fistula-in-ano, recurrent cutaneous vasculitides, achalasia, intestinal dysmotility."

    The Basics Page

    Hello and Welcome!

    This site is focused on treatment of chronic disease like Multiple Sclerosis (MSi) Chronic Fatigue Syndromei (CFSi) and Fibromyalgia (FMSi) an many other diseasesi with antibioticsi. Recent research indicates that Chlamydia Pneumoniae (CPni) plays a role in these diseases.

    Here are the basics that make it easier for people new to the site to get going (if your brain isn't ready for even this much right now-- we've all been there-- read Cpn Simple first):

    Is this a sexually transmitted disease? No. this is chlamydia pneumoniae, a bacteria that can cause pneumonia. It may soon be called chlamydiophilia (meaning in the family of).

    Is chlamydia pneumoniae (CPn) rare?

    No it is a common cause of respiratory illness, but it has an interesting and abnormal way of existing because it can change forms and inhabit the very cells of your body. It can go into your monocytes (a blood cell), your macrophages (an immunei cell), microglia (a brain cell that causes immune reaction) endothelial cells (blood vessels) and others and actually take over.  We say then it has parasitized the cell. Your cell can't do the work it was meant to do now because it's busy supporting the CPn, all the energy of the cell going to make energy for the CPn and it using that energy to make new CPn cells.  For all intents and purposes, your cell is no longer a functional cell and cannot do what it was designed to do.

    How does it spread?

    From person to person when in the respiratory tract it is spread by droplets; in a cough for example. The form that goes from one to another is the elementary body (EB), a tough, little tiny bacteria. It may actually cause pneumonia in the respiratory tract. In some cases once inside, the EB will look for a home (cell) to parasitize so it can have an energy source. Once inside the cell the EB turns into a reticular body (RB) which can produce new infective cells (EB'si) that can find and parasitize other cells. Gradually the cells of your body lose the ability to do what they were meant to do. They are now supporting CPn lifecycle and not taking care of your lifecycle. If it's a monocyte that's infected for example, it is now a factory for EB's not a functional monocyte.  We say then the CPn has parasitized the cell.

    Click here for a detailed explanation of of Cpn

    Why doesn't my immune system kill it?

    This is a complex question. It depends on where the infection is and how advanced it is and what cells have been infected. People who get CPn as a form of pneumonia and do have an active immune response to the bacteria in that instance, though as a form of pneumonia it is mild. Often it is referred to as "walking pneumonia" because people, while ill, are not prostrate with it. Since most people get CPn in their lifetime and get over it as evidenced by rising titers to the bacteria, we can assume that most of the time the immune response is effective enough to for all intents and purposes "get over it."

    In some people however, perhaps because of their genetic makeup or some other factor, the bacteria is carried in blood or immune system cells In this case it "goes underground" and infects the tissues far from the origin of the lungs. Key to this discussion is that your immune system cells are some of the ones that now have these nasty little bacteria hiding in them, so where the immune system goes, the CPn goes too and over time may render the immune cells less effective.

    Second, the germ is INSIDE the cells. Your immune system can't see them in there. Your immune system "sees" what is "you" and what is "foreign" by looking at the proteins on the outside of the cell wall. The outside of this cell is you. For all your system knows, it is a friendly cell, so your immune system is quiet and unexcited. Meanwhile the stealthy pathogen is hiding, slipping into the cells and taking over one cell at a time, and one cell at a time they are now CPn factories not whatever they were meant to be.

    While in some cases CPn is a fairly "benign" germ under certain conditions such as when it is attacked by antibiotics or "starved" it becomes cryptic or shuts down so it can't be harmed or detected. When cryptic it is so quiet and hidden in the body, your body does not really notice it. It then becomes active at some later time causing a "new" infection, perhaps in new parts of the body.

    Changing forms of Cpn

    This bacteria diabolically can change from any form, EB, RB, Cryptic or persistent, to any other form based on the environment. It will choose the form least affected by whatever is threatening it! If you take an antibiotic, let's say for a bladder infection, the CPn will hide in a non replicating and non metabolizing form until the threat is over and your internal environment is less hostile. Virtually all people will have rising titers to CPn over their lifetime, meaning they have been exposed and make antibodies to it from the occasional experience with it as a respiratory pathogen, but also perhaps because they harbor this cryptic formi which later "wakes up" and then subsides or is treated. But as a cryptic pathogen we know little about it. It is just emerging as a known cause of disease. The Centers for Disease Control list it as an Emerging Pathogen in atherosclerosis. See the slides to see pictures of these germs in the cells.here

    Why do steroids help MS then? This question was asked to Dr Wheldon and Dr A. The answer is found here

    Why is it true that your doctor does not tell you about this?

    This is new understanding and it's not well defined yet. For example why is it cryptic in some people? We are not certain at all. The CPn was first seen in 1965 and was identified as the cause of an outbreak of pneumonia in the early 80's. Before that time we had no research or concept about bacteria with lifecycles that included changing forms from one to another and hiding inside the cells of your body. Bacteria were seen as one form either a cocci, or a spirochete, or a rod and you were given one antibiotic and it would go away. Everyone who was trained in medicine was taught this and spent long hours studying these facts.

    Now, research on CPn indicates it plays a role in several chronic diseases by using these peculiar and not well understood ways of being in the body. We have to go back to the books and learn a whole new kind of bacterial science where germs evade and hide from our treatments in ways that seem impossible or outlandish based on prior learning and understanding. New knowledge takes time to filter into the mainstream because physicians spend so many years studying biochemistry and microbiology that they feel like experts. This is so different that it sounds "wrong". Also some other research seems to find it is not a factor in chronic illness, which gives the individual physician a sense this is too new to act on yet.

    For example, some research in CPn in multiple sclerosis (MS) does not find an increased incidence of CPn in the nervous system in people with MS while other research does find CPn DNA in the nervous system of people with MS. This creates doubt in the minds of physicians and a sense that we need to wait for more definitive research before acting. And finally, medicine is extremely slow to change paradigms.

    We have a superb example of this in helicobacter pylori, a bacteria, in peptic ulcer disease. This bacteria was discovered in 1982 by Barry Marshall. He produced a large amount of good research on h. pylorii causing peptic ulcers that went largely ignored. Why? Because "everyone knew" that bacteria could not survive in the stomach (wrong) and he literally had to swallow the bacteria himself and prove that it then caused him an ulcer. When he healed it with antibiotics others to finally accepted his research. It's very difficult to get medicine in general to accept new science, even if it's absolutely correct.

    I bet you're thinking that everyone gets antibiotics for ulcers these days, but you'd be wrong. Up to 9 out of 10 ulcers can be healed by treating with appropriate antibiotics for 2 weeks. Yet today, 23 years after the discovery that ulcers are caused by bacteria, not lifestyle or stress, over 50% of ulcers are STILL treated with proton pump inhibitors (medicines that decrease stomach acid)or other palliative measures that do not kill the bacteria, which also may play a role in gastric cancer. This link is to the American Centers for Disease Control detailing these facts HERE There is a serious "blind spot" in medicine about potential infectious causes of chronic disease. Clearly, even a proven fact can still be ignored by doctors.

    Why does research say it's not a factor sometimes?

    The fact of the matter is that CPn in cryptic form, that means in the cells in an unmetabolizing and non relicating form, is hard to detect. It's virtually impossible to detect without extremely complicated procedures and even in the infectious form it is hard to detect with sensitive DNA (PCRi, below) tests, let alone less sensitive antibody tests. You cannot just see if the person is making antibodies to the bacteria as you would in other infectionsi and as mentioned above, people have rising titers (rising numbers of antibodies) to CPn over their lifetimes as most all of us are exposed repeatedly.

    Instead of checking for antibodies a newer advanced kind of technique must be done called polymerase chain reaction (PCR) to see if CPn is in the tissue. This technique uses small amounts of DNA to detect the presence of the bacteria, not the old method of just screening the blood to see if you have antibodies to CPn.

    The trouble with this is that just like our understanding of CPn is growing so is our understanding about how to detect it. Labs are developing ways of finding and testing for the DNA fragments, however this is still early days. Some labs use one part of the DNA for detection; others use another. This accounts for discrepancy in results as it has not yet been agreed upon by everyone that one lab's approach is the clear winner for accuracy.

    It appears at this time that the Vanderbilt University test is the best at detecting the DNA via PCR. They have doccumented that they have concordance with split samples. In other words, samples tested as positive are positive and negatives are negative in a second test done at another lab. VU finds CPn in the majority of MS cases.

    Another reason we have confusion about whether CPn is in chronic disease or not is some research almost inexplicably seems to be set to NOT find it. For example, just testing the antibody titers of people with MS or CFS or FM and people who have no chronic disease is sure to result in no difference between the groups since this is a common bacteria we all will be exposed to over our lives. Yet we still see some "research" doing exactly this; saying that the titers were the same in both the chronic illness group and the normal group and reaching a conclusion that CPn plays no role in the disease. This is silly! The question is not have you been exposed to CPn and do you have a high titer, the question is whether it is an active infection and or whether it has gone cryptic in your particular case. There is no consensus yet as to how to determine that all important question. However evidence is emerging, and in some areas it's substantial (as it is in the area of atherosclerosis) that CPn is the cause of chronic illness. The CDC lists CPn as an emerging pathogen in the cause of atherosclerosis.

    What is empirical treatment for Cpn?

    If you are tested as positive for Cpn either through antigen or PCR testing, then you clearly know you need to treat it. In that case, know that the standard two week course of a single antibiotic may be inadequate to kill the Cpn in some of it’s life-phases, and re-infection can occur unless a combination antibiotic protocol such as the Vanderbilt or Wheldon protocolsi, is followed. But if you have any of the diseases in which Cpn has been implicated (see list on Home page), it may be worth doing an “empirical” (based on symptoms) course of a combination antibiotic protocol even if your tests for Cpn are negative or uncertain. The antibiotics used are not considered harmful, even for long courses. If you have Cpn involved in your disorder and try this protocol you will likely experience the following: an inflammatory reaction or worsening of some of your symptoms (caused by the bacteria dying and releasing it’s toxin in larger amounts), followed by a gradual improvement in your disease symptoms. Reactions to treatment can range from mild, if your load of Cpn is not great, to very strong and uncomfortable. In the latter case, you have to go very slowly to get to full dose of the protocol. Similarly, improvements in your condition depend on how long you have been infected, and what your total load of Cpn is, and how much permanent damage it might have created to your body.

    Why are there so many antibiotics?

    CPn exists in your body in several different forms. The first is the elementary body. It is small hard and is not actively replicating or metabolizing. It is "looking" for a cell to adhere to and be absorbed by. At this stage amoxicillini can force the EB into the cells.

    Once inside a cell, the EB goes through a transformation becoming metabolically active and replicating. To make this transformation, proteins are used and reassembled to cause the change. It grows huge compared to it's EB size and when the transformation is complete, it takes over the cell's energy system, robbing all the energy for it's own purposes. At this point the tetracycline antibiotics block one of the proteins used in the transformation process (that's how antibiotics work; by blocking proteins used to replicate) so the EB is stuck halfway transformed to an RB (replicating body).

    Now, one of the problems we have with antibiotics in general is that bacteria are very crafty and they have "learned" to resist different antibiotics by replicating using different pathways than before so the blocked protein is no longer needed. This is what we mean by resistance. A certain bacteria is no longer stopped by a certain antibiotic from replicating. The concern about CPn resistence can be stopped in it's tracks by adding a macrolide antibiotic such as rifampin, azithromycin or roxithromycin in addition to tetracyclines because it blocks protein synthesis in a second part of it's pathway. It is effectively impossible for CPn to develop resistance with this double whammy.

    Both the tetracyclines and the macrolides are considered bacteriostatic. They do not kill germs outright, but stop replication so your body can clean up and win the battle without a growing bacterial population to deal with. In the case of CPn however, the EB is stuck halfway converted. It is not able to take over the cell's energy system, so it's on it's own. It has some rudimentary ability to survive on it's own in this anaerobic (without oxygen) state, but not much. As a result a number of the CPn germs will die causing an endotoxini reaction (see below) even though at this stage you are only taking bacteriostatic drugs.

    However a good number of the bacteria will survive even though many die under the stress of living stuck halfway between EB and RB, reducing the overall bacterial loadi by a good margin. This brings us to flagyl (metronidazolei). This antibiotic kills the CPn outright, causing for some people a big reaction to the endotoxin, depending on how extensive the bacterial load still is for them as they begin it's use. For this reason, many people wait a number of months after starting the bacteriostatics before taking their first dose of flagyl. Then, they may take flagyl for only one dose the first time they take it, then wait for the body to recover a bit before dosing again. Pulsing the flagyl kills off some germs,  then gives the body and tissues reacting to the released LPSi a rest.

    The Wheldon regimen recommends using the flagyl for 5 days once every three weeks while continuing to take the other antibiotics. Effectively the CPn is stuck by the bacteriostatic agents waiting to be killed by your next flagyl pulse, though some die simply waiting. The VU protocol recommends flagyl without rest in between and amoxicillin to force the EB's into the cells where they can be killed by the flagyl. This can result in a fairly vigorous LPS reaction (below). Dr A stated in his interview he has no probelm with people pulsing flagyl if they wish to do so.

    What is endotoxin and how is that related to "herxheimer"?  

    Endotoxin is a lipopolysaccharidei (LPS), the protein that is on the outside of every gram negative bacteria.  A gram negative bacteria is one that does not take gram stain.  LPS is very immunogenic meaning it causes a brisk reaction by the immune system to it's presence.  When gram negtive bacteria die, either naturally or by antibiotic, the resulting load of LPS floating around is toxic to the person. "Toxic shock syndrome" is a reaction to LPS in a gram negative bacteria.  The kinds of reactions to LPS vary a bit depending on the bacteria in question, some being more toxic than others.  CPn LPS is not very toxic as far as LPS goes, though it does cause a noticable reaction, it's not threatening as other LPS can be. 

    Syphilis as another gram negative bacteria.  When antibiotics were first applied to this dread disease, the patients got markedly worse as the LPS built up in thier systems.  This was named for the doctors that described it as "Jarisch Herxheimer Reactions".  It has been specualted that the phrase "you have to get worse before you get better" came from this phenomenon.  Today the term herxheimer or herx has been in common usage to mean any reaction to a gram negative bacteria.  I have even heard of people using the phrase in relation to the die off of candida after appropriate anti-yeast drugs have been taken.

    CPn and Cardiovascular Issues

    We have so many links to cardiovascular issues that these are now found on their own page here. Please do read this material even if you are here for something other than cardiovascular problems! While you may be on this site for MS, CFSi or FMSi, it is the cardiovascular research that has all the depth and impressive volume about CPn and how it causes human disease that makes the picture truly clear. Don't make the mistake of thinking this is some new idea or that it has only a few studies just because it is relatively unknown in one field. This is as significant to human disease as understanding staphylococcus, only we are talking in this case about chlamydia pneumoniae. Information about the germ applies and transfers from one field to the next: the important thing is to understand the pathogen.

This is a whole new understanding of how we interact with our environment.

     

    How Chlamydia Pneumoniae Causes Such a Plethora of Diseases

    The following is a condensation of a slightly longer post which can be found at this link.

    Jim K

    Dr. Charles Strattoni's Current Thinking on How Chlamydia Pneumoniae (Cpni) Infection Causes Specific Diseasesi

     

    Dr. Stratton has been observing the emerging literature and research on Cpn, as well as the clinical trials of new anti-chlamydial agents (see footnotes at bottom of this page). His unique and expert microbiological perspective on Cpn helps to shed some light on how such a singular organism can engender such multiple and varied clinical diseases.

    These observations inform Dr. Stratton’s current thinking about the course and pattern of Cpn infection. I’ve attempted to diagram this below to give the reader a feel for the sequence and locus of Cpn in the body, as well as the resulting disease picture. WHile these should be termed theoretical speculations, his theoretical speculations are based on his considerable research, his expertise in microbiology, and his varied clinical experience in treating numerous Cpn infectionsi in a variety of diseases. The picture he describes makes much clearer the multiple pathways and illnesses caused by Cpn, as well as the challenges in treating it.

     Initial Infectious Entry-

    The initial entry into the body for Cpn infection is through the respiratory system. Studies have demonstrated that Cpn crosses from the lungs into the blood stream via infecting macrophages, the first response immunei cells which are trying to combat the respiratory infection.

     

    These circulating infected macrophages both produce EB’s, the infectious spores of Cpn, directly into the blood stream where they attach to and are carried by red blood cells throughout the body (see the picture on our home page), and are taken up by the natural filter organs of the body where they infect those organs with Cpn.

     

    The Inflammatory Trigger:

    Stage is now set for focal diseases: any source of inflammationi attracts infected macrophages and white cells as well as EB carrying red cells as part of the body’s natural repair process. Cpn then transfers from damaged macrophages via EB’s and sets up shop in inflamed areas.

     

    At this point in the infection cycle, the type and locus of the Cpn infection then determines which disease will result and manifest symptomatically (the following is meant for example only, and is not intended to be a complete or exhaustive list):

     

     

    Where specialists, and patients, tend to look at a particular disease as the problem, the microbiological perspective Dr. Stratton brings sees the problem as one of a systemically based infection.

     

    Dr. Stratton now posits that the primary infection in Cpn is of the immune system: immune cells & bone marrow.

    • It is this which, in part, causes such difficulty in getting rid of Cpn.
    • It also causes continuous reinfection if the full spectrum of Cpn infection is untreated.
    • It also lowers the body’s ability to cope with other bacterial and viral infections.
    • This, in turn, fosters further sources of inflammation, and even has the potential (through immuno-incompetence) to compromise the body’s ability to fight cancer and other diseases.

     

    It also answers some common questions that arise in Cpn Combined Antibiotic Protocol (CAPi) treatment.

     

    Why do viruses and cold sores “surface” during CAP treatment?

    This could be due to apoptosis (cell deathi) of infected immune cells and resulting neutropenia which temporarily lowers your immune response until these cells are replaced. Hence latent but suppressed viruses and fungi emerge as immune cells, which previously held them in check, die.

     

    Why is aggressive or rapid treatment of Cpn potentially dangerous?

    In addition to the misery of massive endotoxini release from killing Cpn, and related cytokinei (inflammatory) responses of pain and brain fog, massive kill of Cpn infected cells in the body could potentially cause crashing white counts and potential organ dysfunction or even organ failure (E.G.. liver failure) as large scale apoptosis of infected immune and organ cells occurs. As there is no quantitative measure of infectious load, and no way other than symptoms to know which organs are significantly infected, it behooves physicians treating Cpn to start gradually until some measure of the patient’s response indicates how quickly one can “ramp up” to full treatment. This also suggests that highly potent anti-chlamydial agents such as Rifabutin are not the best first-line treatment, even though they appear to be more effective at killing Cpn more quickly. Once the load has been brought down through gradual introduction of the regular CAP, then a cautious trial of such other agents can be considered.

     

    Dr. Stratton has been paying close attention to reports of drug trials of Rifabutin, a very potent new anti-chlamydial. Even healthy young volunteers showed lowered white cells and liver problems during the Pfizer trials.

     

    Given that Dr. Lee Stewart’s findings that 20-25% of young, healthy blood donors were found to be  flow cytometry positive for Cpn, Dr. Stratton believes that these effects could be not so much side effects of Rifabutin, as it has been currently viewed, but rather a main effect of the drug, that of killing Cpn and resulting death of previously infected cells.

     

    In other words, since Cpn infection is ubiquitous and often sub-clinical, and “side” effects from potent antichlamydial agents in so-called “healthy” volunteers are actually main effects--- the subjects were not healthy after all, just not clinically ill.

     

    Multi-year treatment process-

    Treating Cpn is a multi-year treatment process because of it’s potential to be widespread throughout in body organs, the vascular system, and immune system, as well as it’s toxicity in treatment (from endotoxinsi, porphyrins, inflammatory and cellular apoptosis). The more body systems involved, the longer and more difficult it is to treat, both in terms of tolerance of treatment from endotoxins, porphyriai and apoptosis, as well as being able to get to all the tissues involved, which have differentials in terms of how antibioticsi may concentrate in them. Cpn cells also have active pumps which try to lower concentrations of noxious substances (like antibiotics) which also have to be overcome.

     

    How long treatment will take depends, of course, on the degree of infection, amount of bacterial loadi, severity of infection and number of organs involved, and so on. We don’t have any quantitative measures of infection currently. A good clinician, knowledgeable about the conditions which Cpn can cause, may be able to make an educated guess as to how many organ systems are involved on the basis of history and symptoms. Dr. Stratton sees the degree of reaction to NACi as a useful rough indicator of EB load—the more you react to it the more EB’s you have built up. He also sees the length of time one has been infected (when symptoms may have started) as a rough indicator of the length of treatment (note: one can only guess at this, as we may have initiated Cpn infection from what seemed a mild respiratory infection many years ago, and did not demonstrate serious problems such as MS until years later).

     

    Dr. Stratton’s rule is “Go as fast as you can but no faster,” i.e. as rapidly as your own particular condition can tolerate given the above factors.

     

    He sees that towards the latter phase of treatment, when one is no longer responding with significant reactions to metronidazolei pulses, doing a course of 2 weeks on Flagyl and 2 weeks off while continuing with dual antibiotics, is a useful process to clear remaining tissues. When this is tolerated without significant side effects, a cautious trial of Zithromax and Rifabutin as a final test of Cpn clearance could be tried under careful supervision (watching for plummeting white cells and liver toxicity). At this point one should have cleared organs sufficiently that any apoptosis from the potency of Rifabutin would likely be easily tolerated.

     



    Footnotes: Specific observations

     

    Dr. Stratton has paid particular attention to findings by Dr. Stewart that supposedly young, healthy blood donors are showing positive cultures and flow cytometry for Cpn. Her study showed a number of very important findings with implications for our understanding of Cpn transmission and proliferation in the body.

     

    The first is that approximately 25% of buffy coat samples (a buffy coat is the WBC— white blood cell— portion of spun blood) were culture positive for Cpn. This is not an antigen test, but means that Cpn could actually be cultured or grown in the lab from 25% of white blood cell samples. This means infectious Elementary Bodies are circulating in the blood stream.

     

    The second significant finding in Dr. Stewart’s study, was that approximately 25% of WBC’s were seen by Flow Cytometry to have intracellulari Cpn. The work of Yamaguchi, demonstrating messenger RNA from peripheral blood mononuclear cells, suggests that these intracellular Cpn found by Stewart are viable. Thus, we know that viable Cpn in WBCs and infectious Cpn elementary bodies circulate in the blood stream and can go anywhere blood goes and can infect any tissue. I will go into why Dr. Stratton sees this finding as so important in a bit.

     

    Dr. Stratton also notes that, in her study, this 25% of donors infected with viable Cpn, both intracellular and free EB’s, occurred in so-called “young healthy blood donors.” That is, while they were culture-positive for Cpn, they have no disease symptoms and were considered to be a “normal” control sample. Dr. Stratton links this finding to reports from the Pfizer drug trials for Rifabutin, a highly potent anti-chlamydial. In the drug trials for Rifabutin there were some cases of liver failure and also of plummeting white blood cell counts in “healthy” volunteer subjects. This has been interpreted in some places as a potential side effect of the medication.

     

    From Dr. Stratton’s perspective on the biology of Cpn, and utilizing the evidence from Stewart, Yamaguchi and others, if 25% of “healthy” volunteers are in fact infected with Cpn, including potentially liver and immune system (white cells) cells as important sites of infection (see explanation below), then a highly potent anti-chlamydial agent will kill many Cpn in parasitized cells. This could initiate large-scale apoptosis (natural cell death) of those body cells that have been inhibited from apoptosis by the Cpn which previously infected them.

     

    Let me say that again, a little differently. We know that Cpn inhibits apoptosis of its host cell so that the host cell stays alive and the infecting Cpn survives. If you kill the Cpn invader, the host cell is no longer being prevented from it’s natural death and replacement cycle. And If you kill a bunch of Cpn all at once, you have a bunch of your body or organ cells dying all at once, and it takes time for them to be cleared by the immune system and then replaced by the natural cell replacement process. It is this, on a more gradual scale, which David Wheldoni has noted makes for continuing die-off like symptoms after a Flagyl pulse has been completed.

     

    So, if a whole bunch of liver cells undergo apoptosis at once then liver failure or liver problems could occur. Similarly, if a whole bunch of immune cells undergo apoptosis then, then macrophages and white cells die and severe neutropenia (lowered white count) could occur. From Dr. Stratton’s perspective, these reports may not be a side effect of the Rifabutin, i.e. an unintended effect of a medication, but rather could be due to it’s main effect—killing Cpn.

    BACKGROUND: Demonstration of viable Chlamydia (Chlamydophila) pneumoniae in peripheral blood mononuclear cells (PBMNCs) is essential to understand the involvement of C. pneumoniae in atherosclerosis. Nevertheless, the prevalence of viable C. pneumoniae in the blood of healthy donors has not yet been studied. STUDY DESIGN AND METHODS: The presence of C. pneumoniae transcript in PBMNCs from blood of healthy human donors was assessed by real-time reverse transcription-polymerase chain reaction (RT-PCRi) with primers for C. pneumoniae 16S rRNA, which is more sensitive than genomic-DNA-based analysis, and by the use of staining with fluorescein isothiocyanate-conjugated chlamydia monoclonal antibody (MoAb). RESULTS: Thirteen of 70 donors (18.5%) showed the presence of bacterial transcript in cultured PBMNCs. The prevalence of bacterial detection and bacterial numbers was significantly increased in PBMNC cultures incubated with cycloheximide. Immunostaining of PBMNCs with antichlamydial MoAb also revealed the presence of bacterial antigen in the PBMNCs judged as positive. Nevertheless, cultivation of C. pneumoniae from all PCR-positive donors was unsuccessful. There was no signifi-cant correlation between the presence of chlamydia and either sex or current smoking habits. A possible age variation, however, in the presence of chlamydia in blood of healthy donors was suggested by the results obtained. CONCLUSION: The bacterial transcripts in PBMNCs obtained from healthy donors were detected by the RT-PCR method. Viable C. pneumoniae may be present in healthy human PBMNCs.

    Anaemia of chronic disease (ACD) is a common finding involving iron deficiency and signs of inflammation. Here, we report on two patients with ACD where a persistent infection with Chlamydophila (Chlamydia) pneumoniae (CP) was detected in bone marrow (BM) biopsies. Infection was suspected by routine cytology and confirmed by immunofluorescence, electron microscopy, polymerase chain reaction (PCR) including different primer sets and laboratories and sequencing of the PCR product. This is a first report of chlamydial presence in the BM of anaemic patients. The cases are presented because persistent chlamydial infection may contribute more frequently to chronic refractory anaemia than previously suspected.

    This multicenter study evaluated the tolerance and potential pharmacokinetic interactions between azithromycin and rifabutin in volunteers with or without human immunodeficiency virus infection. Daily dosing with the combination of azithromycin and rifabutin was poorly tolerated, primarily because of gastrointestinal symptoms and neutropenia. No significant pharmacokinetic interactions were found between these drugs.

    A 14-day, randomized, open, phase I clinical trial was designed to examine possible pharmacokinetic interactions between rifabutin and two other antibiotics, azithromycin and clarithromycin, used in the treatment of Mycobacterium avium complex infections. Thirty healthy male and female volunteers were divided into five groups of six participants each: 18 received 300 mg/day of rifabutin, 12 in combination with therapeutic doses of either azithromycin or clarithromycin; the remaining 12 received azithromycin or clarithromycin alone. On day 10 the study was terminated because of adverse events, including severe neutropenia. Fourteen participants who received rifabutin developed neutropenia, including all 12 participants who received azithromycin or clarithromycin concomitantly. Analyses of serum revealed no apparent pharmacokinetic interaction between azithromycin and rifabutin. However, the mean concentrations of rifabutin and 25-O-desacetyl-rifabutin (an active metabolite) in participants who received clarithromycin and rifabutin concomitantly were more than 400% and 3,700%, respectively, of concentrations in those who received rifabutin alone. Physicians should be aware that recommended prophylactic doses of rifabutin may be associated with severe neutropenia within 2 weeks after initiation of therapy, and all patients receiving rifabutin, especially with clarithromycin, should be monitored carefully for neutropenia.

     

    Chlamydia pneumoniae and Rosacea: A potential link?

     

    While the exact pathology of rosacea is not completely understood or widely agreed upon, recent studies suggest that chronic inflammation likely plays a role in many of the symptoms associated with this disease.

     

    Background

    Rosaceai is a chronic disorder of still unknown cause that affects an estimated 14 million Americans.1 Rosaceai often initially presents itself with transient flushing and redness of the cheeks, nose, forehead and chin, but it may also involve other areas of the body, including the ears, neck, and chest. With time the transient flushing becomes more frequent, the transient redness tends to become more persistent, and papules, pustules, and visible blood vessels called telangiectasias may also appear. Facial swelling, or edema, also often accompanies rosacea, as do burning or stinging sensations of the affected areas. In addition, many people with rosacea often also have the concomitant chronically irritated eye and eyelid symptoms of ocular rosacea and blepharitis.2

    The exact pathology of rosacea is not completely understood or widely agreed upon, but recent studies suggest that chronic inflammation likely plays a role in many of the symptoms associated with this disease. And the chronic inflammation and blood vessel involvement in this disorder may well point to involvement of gram-negative bacteria, or more particularly their endotoxins, which have been shown to elicit similar response upon entry into the bloodstream.

    While several gram-negative bacteria, including H. pylori and B. oleronius (found in Demodex folliculorum) have been associated with rosacea in the past, they have not been shown to enter the bloodstream, and thus they are unlikely to play anything more than a secondary role in the disease. Chlamydia pneumoniae, however, has been associated with rosacea in one small study, and studies in other inflammatory diseases in which it is being studied closely indicate that it is quite capable entering and persisting in the bloodstream, as well as producing the type of chronic inflammatory response that has been associated with rosacea. This evidence suggests the potential for C. pneumoniae's involvement in rosacea, at least secondarily.

     

    Evidence

    Although the exact pathology of rosacea is still unknown, recent studies suggest that chronic inflammation likely plays a role in many of the symptoms associated with the disease. Supporting the role for chronic inflammation is the host of elevated proinflammatory cytokines (TNF-a, IL-1B), matrix metalloproteinases (MMP-1, MMP-3, and MMP-9), nitric oxide (NO), and reactive oxygen species (ROSi) that have been associated with rosacea in recent studies.3 Rosacea has been associated with elevated vascular endothelial growth factor (VEGF) in recent studies as well.4

    It is important to note that the discovery of these elevated inflammatory mediators in rosacea may suggest important clues to an underlying disease etiology when comparing them as a whole to other known pathologies. And indeed, the elevated cytokines, MMPs, VEGF, NO and ROS associated with rosacea, match closely with the known pathology of early gram-negative sepsis, an infection of the bloodstream caused by toxin-producing bacteria.5

    In fact, endotoxins, or rather lipopolysaccharides (LPSi), portions of the outer membrane of gram-negative bacteria, are widely known to induce a variety of inflammatory responses, ranging from mild to severe inflammation (and death), depending on the virulence of the bacteria endotoxins themselves.6 Recent studies suggest as well that vascular endothelial growth factor (VEGF) itself may actually be a key biomarker for sepsis.7

    While gram-negative bacteria such as H. pylori and even B. oleronius (found in Demodex folliculorum) have been associated with rosacea in past studies, since these bacteria have not been shown to enter the bloodstream, one would not expect them to produce pathology similar to early sepsis.8 So looking at other inflammatory diseases for clues relating to associated gram-negative bacteria, one such pathogen, Chlamydia pneumoniae, stands out for its association with many inflammatory diseases, including Atherosclerosis, Multiple Sclerosisi, Asthmai, Alzheimer's and other inflammatory disorders.9

    Interestingly, one small study has linked C. pneumoniae with rosacea directly, detecting serum antibodies of C. pneumoniae in 8 of 10 patients with rosacea and detecting C. pneumoniae specimens in 4 of 10 cheek biopsy.10 Other studies suggest that infection with C. pneumoniae can lead to pustular rashes (acute generalized exanthematous pustulosis) and increased VEGF production, as in the case with wet age-related macular degeneration.11,12 These of course are most likely caused as by-products of the chronic inflammation associated with this pathogen, but I point them out since papule and pustule rashes and increased VEGF production are symptoms of rosacea.

    Persistent C. pneumoniae infection of epithelial cells has been shown to produce chronic blood vessel inflammation, resulting in production of a host of cytokines and growth factors such as those found in rosacea as well as promoting a "foci of inflammatory responses in addition to promoting cellular proliferation, tissue remodeling and healing processes".13 And additional studies suggest that chlamydiae, while classified as gram-negative bacteria due to their outer LPS coating, are actually a distinct group of eubacteria, with a unique multi-form, intracellulari and extracellular development cycle, allowing them to change between forms and promote the persistent infection that may lead to chronic inflammatory disease.14

    Another clue potentially linking rosacea with C. pneumoniae involves recent studies in the anti-microbial peptides, cathelicidins, and their activity in rosacea. These recent studies have identified unusually high levels of kallikrein activated cathelicidins in rosacea and suggest that these two substances may be in part responsible for producing the papules and pustules associated with rosacea as well as in promoting the angiogenesis associated with the disease.15,16,17 Some additional studies have shown too that C. pneumoniae seems to invoke unusually high levels of cathelicidin activity and that endotoxins in general activate the kallikrein-kinin system.18,19 Intriguingly, still other studies suggest that cathelicidins seem to be ineffective in clearing C. pneumoniae infection.20 Potentially this is due to C. pneumoniae's ability to revert between forms, effectively evading the immune response. If this were correct then a C. pneumoniae infection, with the resulting ineffective yet elevated levels of activated cathelicidins, could indeed explain the unusual cathelicidin activity found in rosacea.

    Dr. Charles Strattoni, MD, at Vanderbilt University, in a recent interview, 21 summarized his observations of some of the emerging research on C. pneumoniae. He noted how C. pneumoniae crosses from the lungs to the bloodstream via infected macrophages. The spore-like Elementary Bodies (EBi's) then circulate in the bloodstream to infect other organs throughout the body, including the liver, bone marrow, spleen, kidneys and skin.21 Potentially this might explain how C. pneumoniae, whose initial entry into the body is via the respiratory system, might arrive in the skin to cause rosacea. This may explain too the discovery of C. pneumoniae in cheek biopsy of rosacea as in the study discussed above.

     

    Conclusion

    In summary, Chlamydia pneumoniae may be involved at least secondarily in the etiology of rosacea. C. pneumoniae is a persistent, gram-negative bacteria known to enter and exist in the epithelial cells of the bloodstream, and it is known to produce the type of chronic inflammation that can be found in rosacea. Studies suggest C. pneumoniae may be involved with the etiology of many other inflammatory diseases, and intriguingly, a small study suggests a potential link with rosacea itself. Combined, this evidence would suggest more study related to C. pneumoniae's potential involvement in rosacea is necessary.

    Chlamydia Pneumoniae in CFS/ME & Fibromyalgia


    Chronic Fatigue Syndromei, Fibromyalgia & Chlamydia Pneumoniae[1]

    Introduction

    (Note: the original page for this became non-functional for some reason. This copy is identical except for some minor text layout details)

    Chronic Fatigue Syndrome (CFS), also called Chronic Fatigue Immunodeficiency Disorder (CFIDSi), or called Myalgic Encephalomyelitisi (ME) in Great Britain. CFS affects 1 million Americans, with "tens of millions" more who have a fatigue condition that doesn't meet the strict criteria for Chronic Fatigue Syndrome.[2] According to the Center for Disease Control (CDC), which considers CFS an accepted medical condition,[3] there is no officially known cause or cure for CFS or for the related, and often co-occurring, condition of Fibromyalgia Syndrome (FMSi).[4]

    Despite the CDC's affirmation, the syndrome and its diagnosis is still considered controversial even in this day and age. Some doctors continue to insist that Chronic Fatigue Syndrome is not a "real" disease entity. It may be rather a surprise to it's sufferers when, naively seeking medical assistance, they find that their doctor doesn't believe that their symptoms are from a "real disease" or merits medical treatment. That there is no known "test" for Chronic Fatigue Syndrome that can conclusively demonstrate its existence is one of the difficulties here.

    Perhaps another difficulty is that medical practitioners are socialized to believe that feelings of their own helplessness are a sign of personal failure. A solution to this psychological conundrum is to blame the patient by "psychologizing" the problem i.e. "It's in your head." Fortunately, acceptance of the legitimacy of the disease has increased in recent years, even if conventional medical treatment for it continues to have little to offer of help.

    As the causal factors of CFS are considered unknown, conventional medical treatment for it and for Fibromyalgia Syndrome are all palliative (symptomatic) in nature: antidepressants for mood and pain associated with it, medications for sleep, stimulants for the fatigue, behavioral strategies, and so on. These can help make life bearable but don't fundamentally change the condition. [5]
