Retroviruses and Chronic Fatigue Syndrome

One of the themes of this blog is that chronic infections, exacerbated by bad diets and malnutrition, are at the root of nearly all health problems.

With the invention of new tools for microbiology over the last 20 years, scientists are for the first time able to study chronic parasitic infections, albeit with difficulty. I mentioned a few weeks ago that this should be the dawn of a “golden era of antimicrobial medicine.” And maybe it is: careful studies are now linking specific pathogens to chronic diseases and discovering the mechanisms by which they cause disease.

A good example of emerging science is the progress made since 2002 in understanding a retrovirus family that is now firmly linked to cancer and chronic fatigue syndrome and may soon be linked to other diseases.

Beginning of the Story:  Human Anti-Viral Immunity and Chronic Fatigue Syndrome

Our story begins back in the 1970s with studies of the role of interferons in defending human cells against viruses. Interferons are a key part of the immune defense against intracellular pathogens – the ones that cause most human chronic diseases.

Following the effects of interferons, researchers discovered an enzyme known as ribonuclease L (RNase L). RNase L is upregulated by interferons and its function is to degrade RNA, both viral and human, to stop viral replication. [1]

Aside: High levels of RNase L destroy so much human RNA that the cell dies. This is probably adaptive for the host, since cell apoptosis also kills many pathogens within. However, it shortens lifespan. RNase L knockout mice have extended lifespans. [1]

In 1997, RNase L was found to be strongly upregulated in chronic fatigue syndrome patients. [2] This showed that chronic fatigue patients usually have viral infections. Whether the viruses were causing chronic fatigue, or just “hitchhiking” with a disease that suppressed the immune system (perhaps via a bacterial infection?), remained an open question.

A Link Between RNase L and Prostate Cancer

By the early 2000s it was established that a common (allele frequency 35%) gene mutation, the “R462Q” mutation which substitutes a glutamine for an arginine in the “hereditary prostate cancer 1” locus, raised the risk of prostate cancer. A man with two copies of this mutation has twice the risk of prostate cancer; one copy raises the risk by 50%. About 13% of prostate cancer cases were attributable to this mutation. [1, 3, 4]

It was important, therefore, to determine which protein this locus coded for. A breakthrough finding, made in 2002, was that the “hereditary prostate cancer 1” locus was the gene for RNase L. [5]

It was soon shown that the R462Q mutation decreased the effectiveness of RNase L at cleaving viral RNA. This placed prostate cancer in a new light: it implied that an unknown virus against which RNase L defends was a probable cause of prostate cancer. When RNase L function was impaired by the R462Q mutation, the infection became more virulent, and prostate cancer rates were higher. [1]

The search for this unknown virus was on.

The discovery of “xenotropic murine leukemia virus-related virus” (XMRV)

The strategy was basically to take prostate tumors and search for viral RNA, looking for viruses that were most common in patients who had the double R462Q mutation.

In 2006 one of these searches yielded fruit.  A new gamma retrovirus was found in 8 of 20 prostate cancer patients with double R462Q mutations, but only 1 of 66 patients without the double mutation. [6]

This gamma retrovirus shared a lot of RNA with a family known as the xenotropic murine leukemia viruses (MuLVs). It was dubbed “xenotropic murine leukemia virus-related virus” (XMRV). Despite the sound, it is not a murine (mouse) leukemia virus; it merely shares a lot of nucleic acids with those viruses.

Back to chronic fatigue syndrome

In 2009 a paper was published in Science reporting that XMRV was found in peripheral blood cells of 67% of chronic fatigue patients but only 3.7% of healthy controls. [7] This study was done by a group at the Whittemore Peterson Institute in Reno, Nevada.

Aside:  The Whittemore Peterson Institute has a nice Q&A about this virus and its role in chronic fatigue syndrome here.

A number of researchers tried and failed to reproduce these results. For instance, a group from the Centers for Disease Control failed to detect XMRV proteins in 51 chronic fatigue and 53 healthy patients. [8]

Perhaps proteins are just not the right molecules for detecting this virus. A new paper has just appeared that links XMRV more strongly than ever to chronic fatigue. It looked at DNA for viral genes inserted into the human genome and found XMRV sequences in 86.5% of chronic fatigue patients but only 6.8% of controls. [9] This paper was held back from publication since June because of its conflict with the CDC paper (see “Why I Delayed XMRV Paper”), but has now been released.

These percentages are impressive and, if they hold up, would seem to make it unlikely that XMRV is merely a “passenger” virus hitchhiking on a suppressed immune system. It may be causal for chronic fatigue.

Will anti-retroviral therapies be effective?

Clinical trials are extremely expensive and the drug companies seem to be waiting for XMRV to be proven as the cause of chronic fatigue before undertaking trials. From the Wall Street Journal:

Norbert Bischofberger, chief scientific officer at Gilead Sciences Inc., the leading maker of HIV drugs, said the company might consider a small pilot trial but would like to see stronger evidence that the viruses cause CFS before launching a large trial. Still, “I’m very open, and this would be a great opportunity,” he said.

A spokesman for Merck & Co., another major manufacturer of HIV drugs, said: “A clinical trial program would be possible to develop only after further substantial evidence of an association with CFS.” [10]

But some aren’t waiting for trials. Anti-retroviral drugs developed for AIDS are being prescribed off-label:

Jamie Deckoff-Jones, 56 years old, a doctor and CFS patient in New Mexico, has been blogging about her experiences and those of her 20-year-old daughter. Both tested positive for XMRV and are taking a combination of three anti-retrovirals.

Dr. Deckoff-Jones said a year ago she could only get up for short periods during the day. After five months on the drugs, she flew last week to Reno for an XMRV conference. Her daughter was able to go to a party and is enrolling in community college. “This is all very new, and there is no way to know if improvement will continue,” Dr. Deckoff-Jones wrote in an email, “but we appear to be on an uphill course.” [10]

Chronic fatigue patients are celebrating the progress:

Many [CFS patients] were ecstatic at news that the second study was being published.

“We’re really hoping this will blow the lid off,” said Mary Schweitzer, a historian who has written and spoken about having the illness. “Patients are hopeful that now the disease itself might be treated seriously, that they’ll be treated seriously, and that there might be some solution.” [11]

It’s sad that for decades many haven’t taken chronic diseases seriously. The absence of a known cause reflected only the lack, until recently, of microbiological tools capable of detecting and characterizing intracellular pathogens.

Had doctors taken these diseases seriously, the accumulating evidence that these were chronic infectious diseases caused by intracellular parasites might have encouraged them to look for the sort of dietary and nutritional therapies for chronic disease that we advocate on this blog. Though diet and nutrition by themselves will probably not cure these diseases, they can greatly slow disease progression and improve the odds of a cure.

A new name for XMRV: Human Gamma Retrovirus

The Whittemore Peterson Institute recently hosted the first official scientific symposium on XMRV. Dr. Joseph J. Burrascano reported from the symposium:

We formed a working group to be in constant touch and we plan to meet regularly because advances are coming so rapidly.

Big news that everyone should know and adopt is that we have proposed a name change for the virus.

This virus is a human, not mouse virus, and it is the first and so far only gamma-retrovirus known to infect people. Also, it is clearly not an “endogenous” retrovirus (one that is present in all genomes due to ancient infection).

Because of all of this, and because of the desire to begin on the right track, the new name of the virus is HGRV- Human Gamma Retro Virus. The illness caused by this infection is named HGRAD- Human Gamma Retrovirus Associated Disease.

We plan to announce this at the upcoming NIH retroviral conference this September.

Definitely stay tuned- the volume of new and important information about this virus and its disease associations is increasing rapidly and in my opinion should be a concern to every patient with chronic neuro-immune diseases, including those with chronic Lyme. [12]

It sounds like some exciting findings may be on the way.


This case is a fascinating illustration of the twisting turns that scientific research can take. The early discovery of a link between anti-viral immunity and prostate cancer may now lead to a cure for chronic fatigue syndrome. At least, we can hope so.

As one of the pioneers, Dr. Robert Silverman, describes it,

One of the remarkable aspects of being a scientist, is that you never know where your scientific journey will lead. [1]

Science takes a lot of patience, diligence, and persistence. It’s gratifying when all that work is rewarded by discovery.

  1. Hi Paul,

    You might want to look into the links between CFS and adrenocorticotropin hormone (ACTH) deficiency. I’ve seen plenty of evidence that CFS could potentially be an autoimmune disease of the hypothalamus or pituitary.

  2. Paul, I’m in awe of the depth of your knowledge on such a wide variety of subject.

  3. Hi Robert,

    Thanks for the suggestion, I’ve put it on my to-do list. Do you have a link to an introduction? As neither I nor any of my family and friends have had CFS, I’m not as deep into its literature as some other diseases.

    erp, thank you, but my erudition comes from the same source as Samuel Johnson’s wit. I steal.

  4. Wherever it comes from, it’s awesome.

  5. extremely fascinating, and great blog post!

  6. paul, i know that people with CFS and FM often tremendously benefit from

    it seems to be a stron immune modulator or something.
    could be an additional piece of the puzzle.

  7. This is a review on the status of the adrenals and its relationship to CFS:

  8. Thanks Robert. One thing I learned at is that many people with chronic illnesses have disrupted thyroid and adrenal axes. But the question is whether these are causes or symptoms of the disease.

    One wildcard is that infections of the thyroid can cause both hyperthyroidism and hypothyroidism; I imagine the adrenal glands can be infected also and suffer impairment by that route.

    There are some papers suggesting that infections elsewhere, e.g. hepatitis C, can cause circulating cytokines to damage the hypothalamus, e.g. I’m not a believer in action-at-a-distance in biology, but maybe.

    Regarding autoimmune possibilities, my general prejudice is that they’re mostly the result of infections and tend to disappear soon after the infection. One review of CFS states that “Immune dysfunction as the cause of CFS is thus far the weakest hypothesis” ( and since that agrees with my prejudices I will believe it pending further investigation. 🙂

    I have resisted delving into adrenal biology but I’ve noticed that a growing number of people in the blogosphere, e.g. Matt Stone, seem to think it’s the key to everything.

  9. qualia,

    Thanks. Low-dose naltrexone seems like a wonder drug, and Dr. Bihari’s discovery is a heart-warming story. Figuring out to try a subpharmacological dose between 2 am and 4 am has to be one of the cleverest ideas of recent medicine; and rarely does a clinical practitioner come up with an innovation and get it widely adopted and investigated without any funding or research support.

    I might be able to do a blog post on it after the book is out. I’ll be a little swamped until then.

  10. Paul,

    Have you looked into any of the subsequent literature about XMRV? It seems highly likely at this point that it was a result of contamination:


  11. What do you know about the use of cimetidine/ tagamet as immune booster and energizer for chronic fatigue?

  12. I was doing better on PHD for a while, and then I keep getting sick. I went to a chronic fatigue doctor and tested positive (high IgG, which indicates a past infection, rather than high IgM, which would indicate an active one) for a lot of viral infections – Epstein-Barr, Cytomegalovirus, Herpes Simplex 1 or 2, and maybe even C. Pneumoniae. Some of the things I’ve noticed is that my taste for protein is lower than it was when I started eating a paleo/primal type diet. I know protein restriction can help with viruses, so hopefully listening to my body is good.

    Also, it’s very, very hard for me to intermittently fast. When I do so, I find that I get so tired after I eat that I am completely useless. Finally, Vitamin C is one of the few things that really helps me – I feel great on days when I take upwards of 8 g (I think the last time I tested to bowel tolerance it was around 40 g at first, then later around 36 g). Why aren’t more doctors willing to prescribe antivirals and run the type of tests which my chronic fatigue doc ran for me, but are very willing to prescribe antibiotics?

  13. Hi Paul,

    Do you have any new thoughts and recommendations concerning “chronic fatigue syndrome” these days? I’m reading some of your old posts with interest, and am wondering about IF vs. ketogenic diets vs. ??? for my husband, who has suffered from autoimmune issues all of his life, with worsening fatigue and “wasting” type of symptoms recently…

    Thanks so much,

    • Hi Sara,

      I strongly recommend IF and do not recommend a ketogenic diet. Try to concentrate his food intake in a narrow window in the afternoon, and take no calories during a 16-20 hour overnight fast except black coffee, green tea, and maybe some salted bone stock and vegetables soup to lessen the stress of the fast. Work on circadian rhythm entrainment, sunshine and daily exercise. Eat plenty of PHD food though during the feeding window, with emphasis on supplemental foods like liver, egg yolks, spinach, seafood, potatoes.

  14. Hi Paul, I am an exercise physiologist with a client who has chronic fatigue syndrome – I have lent her a copy of your book and have prescribed a graded exercise program. She has recently decided to purchase this frequency generator zapper device that is supposedly designed to kill parasites
    It looks dodgy to me, but I don’t have the knowledge to tell her not to waste her money – especially because she is at her wits end. I would be pleased to hear your views.

  15. Hi Paul, where do we go for chronic infection testing located outside of the gut? Lyme doc perhaps? I’m wanting to get a comprehensive analysis of any systemic pathogens I may have. Most doctors are completely uneducated about such things. I’m 20 years old and have extreme fibromyalgia. All of my muscles, tendons, and ligaments are affected as well as my joints. Seems like my whole body is calcified. Blood flow is incredibly sluggish. This happened after a 5 month course of accutane and an extremely stressful lifestyle. Have been on your diet for the past year and a half (modified to eliminate any potential foods that don’t agree with me). Thanks

  16. Paul,
    After much pain and suffering I have been diagnosed with Lyme disease. So you have any thoughts as to keep healthy during treatment? And would cutting carbs lower be better For this kind of disease?
    Thanks a lot for everything you do!

    • Hi Keven,

      Intermittent fasting and circadian rhythm entrainment are crucial. You could try extending the daily fast beyond 16 hours, e.g. feast for 3 hours in the early afternoon and then fast for 21 hours. I would stick with 30% carbs.

      Best, Paul

  17. Hi Paul!

    I’ve recently been diagnosed with CFS, and I found your article very interesting! Whilst research into CFS definitely could move quicker, I’d be interested to hear your take on how the science has progressed over the last six years. Is XMRV still a being considered? I find it all somewhat overwhelming, and I’m about to spend ££££ on a bunch of tests for Lyme, EBV, CMV, etc., but XMRV or Human Gamma Retrovirus has not been mentioned to me. Any insight would be very much appreciated!! Many thanks for your great work!

    This often-overlooked airborne pathogen gave me Fibromyalgia and is known to cause myelitis, adrenal insufficiency, anemia, zinc deficiency, and encephalitis/meningitis, etc. Can it ever cause ME/CFS? (It likes zinc, so does it like to go to the prostate?)

    I’d like to share information I learned during my workplace’s outbreak of an underdiagnosed airborne infectious disease that can cause malignancies, precancerous conditions, rheumatological diseases, connective tissue diseases, heart disease, autoimmune symptoms, inflammation in any organ/tissue, adrenal insuffiency, seizures, migraines, mood swings, hallucinations, etc. and is often undiagnosed/misdiagnosed in immunocompetent people. 80-90+% of people in some areas have been infected, and it can lay dormant for up to 40 years in the lungs and/or adrenals.

    My coworkers and I, all immunocompetent, got Disseminated Histoplasmosis in Dallas-Fort Worth from roosting bats, the most numerous non-human mammal in the U.S., that shed the fungus in their feces. The doctors said we couldn’t possibly have it, since we all had intact immune systems. The doctors were wrong. Healthy people can get it, too. And we did not develop immunity over time. We’d get better and then progressively worse, relapsing periodically and concurrently every year.

    More than 100 outbreaks have occurred in the U.S. since 1938, and those are just the ones that were figured out, since people go to different doctors. One outbreak was over 100,000 victims in Indianapolis.

    It’s known to cause hematological malignancies, and some doctors claim their leukemia patients go into remission when given antifungal. My friend in another state who died from lupus lived across the street from a bat colony. An acquaintance with alopecia universalis and whose mother had degenerative brain disorder has bat houses on their property.

    Researchers claim the subacute type is more common than believed. It’s known to at least “mimic” autoimmune diseases and cancer and known to give false-positives in PET scans. But no one diagnosed with an autoimmune disease or cancer is screened for it. In fact, at least one NIH paper states explicitly that all patients diagnosed with sarcoidosis be tested for it, but most, if not all, are not. Other doctors are claiming sarcoidosis IS disseminated histoplasmosis.

    What if this infection, that made me and my coworkers so ill, isn’t rare in immunocompetent people? What if just the diagnosis is rare, since most doctors apparently ignore it? Especially since online documents erroneously state it’s not zoonotic.

    Older documents state people who spend a lot of time in a building with roosting bats, in caves, working as landscapers, construction workers, pest control workers, etc. are known to get Disseminated Histoplasmosis, but the info appears to have been lost, for the most part. And now bat conservationists encourage people to leave bats in buildings/homes. What a terrible mistake they’ve made.

    This pathogen parasitizes the reticuloendothelial system/invades macrophages, can infect and affect the lymphatic system and all tissues/organs, causes inflammation, granulomas, and idiopathic (unknown cause) diseases and conditions, including hematological malignancies, autoimmune symptoms, myelitis, myositis, vasculitis, panniculitis, dysplasia, hyperplasia, etc. It causes hypervascularization, calcifications, sclerosis, fibrosis, necrosis, eosinophilia, leukopenia, anemia, neutrophilia, pancytopenia, thrombocytopenia, hypoglycemia, cysts, abscesses, polyps, stenosis, perforations, GI problems, hepatitis, focal neurologic deficits, etc.

    Many diseases it might cause are comorbid with other diseases it might cause, for example depression/anxiety/MS linked to Crohn’s.

    The fungus is an Oxygenale and therefore consumes collagen. It’s known to cause connective tissue diseases (Myxomatous degeneration?), rheumatological conditions, seizures, and mental illness. Fungal hyphae carry an electrical charge and align under a current. It causes RNA/DNA damage. It’s known to cause delusions, wild mood swings (pseudobulbar affect?), and hallucinations. It’s most potent in female lactating bats, because the fungus likes sugar (lactose) and nitrogen (amino acids, protein, neurotransmitters?), releasing lactase and proteinases to obtain them. What about female lactating humans…postpartum psychosis (and don’t some of these poor women also have trouble swallowing)? The bats give birth late spring/summer, and I noticed suicide rates spike in late spring/early summer. It’s known to cause retinal detachment, and retinal detachments are known to peak around June-July/in hot weather. A map of mental distress and some diseases appear to almost perfectly overlay a map of Histoplasmosis. Johns Hopkins linked autism to an immune response in the womb. Alzheimer’s was linked to hypoglycemia, which can be caused by chronic CNS histoplasmosis. Cancer is known to occur more often near rivers than in mountains or deserts, just like this infection. The bats eat moths, which are attracted to blue and white city lights that simulate the moon the moths use to navigate. Bats feed up to 500 feet in the air and six miles away in any direction from their roost, but not when it’s raining or when the temperature is less than approximately 56° F. The fungus can grow in bird feces, but birds don’t carry it because their body temperature is too high, killing the fungus.

    I believe the “side effects” of Haldol (leukopenia and MS symptoms) might not always be side effects but just more symptoms of Disseminated Histoplasmosis, since it causes leukopenia and MS symptoms. What about the unknown reason why beta receptor blockers cause tardive dyskinesia? The tinnitus, photophobia, psychosis “caused” by Cipro? Hypersexuality and leukemia “caused” by Abilify? Humira linked to lymphoma, leukemia and melanoma in children? Disseminated Histoplasmosis is known to cause enteropathy, so could some people thought to have nonsteroidal anti-inflammatory drug enteropathy have it and taking NSAIDs for the pain/inflammation it causes, and the NSAIDs aren’t the actual culprit?

    From my experience, I learned that NO doctor, at least in DFW, will suspect subacute and/or progressive disseminated histoplasmosis in immunocompetent people. Some doctors, at least the ones I went to, will actually REFUSE to test for it, even when told someone and their coworkers have all the symptoms and spend a lot of time in a building with bats in the ceiling. Victims will be accused of hypochondriasis. (My doctors told me only farmer’s get it, it’s only in bird feces, and it only infects the lungs…wrong, wrong, and wrong!) In fact, the first doctor to diagnose me was a pulmonologist, and the only reason he examined me was to try to prove that I didn’t have it, when I really did. No doctor I went to realized bats carry the fungus. And NO doctor I went to in DFW, even infectious disease “experts,” understand the DISSEMINATED form, just the pulmonary form, and the only test that will be done by many doctors before they diagnose people as NOT having it is an X-ray, even though at least 40-70% of victims will have NO sign of it on a lung X-ray. It OFTEN gives false-negatives in lab tests (some people are correctly diagnosed only during an autopsy after obtaining negative test results) and cultures may not show growth until after 6-12 weeks of incubation (but some labs report results after 2 weeks).

    One disease of unknown cause that could be caused by Disseminated Histoplasmosis: I suspect, based on my and my coworker’s symptoms (during our “rare” infectious disease outbreak) and my research, that interstitial cystitis and its comorbid conditions can be caused by disseminated histoplasmosis, which causes inflammation throughout the body, causes “autoimmune” symptoms, and is not as rare as believed. I read that “interstitial cystitis (IC) is a chronic inflammatory condition of the submucosal and muscular layers of the bladder, and the cause is currently unknown. Some people with IC have been diagnosed with other conditions such as irritable bowel syndrome (IBS), fibromyalgia, chronic fatigue syndrome, allergies, and Sjogren’s syndrome, which raises the possibility that interstitial cystitis may be caused by mechanisms that cause these other conditions. In addition, men with IC are frequently diagnosed as having chronic nonbacterial prostatitis, and there is an extensive overlap of symptoms and treatment between the two conditions, leading researchers to posit that the conditions may share the same etiology and pathology.” Sounds like Disseminated Histoplasmosis, doesn’t it?

    My coworkers and I were always most ill around April/May/June, presumably since the Mexican Free-tail bats gave birth in Texas during May (and the fungus was most potent), and fall/Thanksgiving to December, for some unknown reason (maybe migrating bats from the north?). We had GI problems, liver problems, weird rashes (erythema nodosum, erythema multiforme, erythema marginatum/annulare, etc.), plantar fasciitis, etc., and I had swollen lymph nodes, hives, lesions, abdominal aura, and started getting migraines and plantar fasciitis in the building, and I haven’t had them since I left. It gave me temporary fecal incontinence, seizures, dark blood from my intestines, tinnitus, nystagmus, blurry viion/floaters/flashes of light, benign paroxysmal positional vertigo, isolated diastolic hypertension, what felt like burning skin, various aches and pains (some felt like pin pricks and pinches), tingling, tremors, “explosions” like fireworks in my head while sleeping, temporary blindness, and chronic spontaneous “orgasms”/convulsions. Suddenly I was allergic to Comice pears (latex fruit allergy or oral allergy syndrome?). I had insomnia (presumably from the fungus acidifying the blood, releasing adrenaline) and parasomnias. It felt like strong bursts of eletrical shocks or stady electrical currents in my body, which now feel like low electrical currents at times, mostly at night. I suddenly had symptoms of several inflammatory/autoimmune diseases, including Fibromyalgia, Sarcoidosis, ALS, MS, Sjogren’s syndrome, etc. that have disappeared since leaving the area and taking nothing but Itraconazole antifungal.

    No one, including doctors (we all went to different ones), could figure out what was wrong with us, and I was being killed by my doctor, who mistakenly refused to believe I had it and gave me progressively higher and higher doses of Prednisone (at least 2 years after I already had Disseminated Histoplasmosis) after a positive ANA titer, until I miraculously remembered that a visiting man once told my elementary school class that bats CARRY histoplasmosis….so much of it that they evolved to deal with the photophobia and tinnitus it causes by hunting at night by echolocation. There’s a lot more. I wrote a book about my experience with Disseminated Histoplasmosis called “Batsh#t Crazy,” because bats shed the fungus in their feces and it causes delusions and hallucinations, I suspect by the sclerotia fungal mycelia can form emitting hallucinogens (like psilocybin and dimethyltryptamine) along with inflammation in the CNS. (Schizophrenics have 2X of a chemical associated with yeast, part of the fungal life cycle.)

    Thank you for your time,

    Susan McIntyre

    P.S. Doesn’t this infection share all the same symptoms with Gulf War Syndrome?
