Chronic Fatigue causing Virus (HHV-6)

Human Herpes Virus 6 linked to Chronic

Lyme disease:Its Link to Chronic Fatigue Syndrome, Fibromyalgia, Fatigue, and

Cancer

First reported in 1986, human herpesvirus 6 (HHV-6) has since become one of the most widespread

members of human herpes viruses and comes in two related variants: HHV-6A and HHV-6B. And though

similar, there areclear differences in their epidemiology and pathogenicity.

HHV-6B is acquired in early childhood (often in daycare centers) and is responsible for infecting up to

90% of most populations during infancy. HHV-6A behaves quite differently as it is generally not seenuntil adulthood. Both versions of the virus can be found in saliva and are presumably spread this way as

well.

The HHV-6 virus is of greatest concern to immunocompromised patients. Among those at the greatest

risk of severe HHV-6 complications are those who have undergoneorgan or bone marrow transplants or

who are HIV positive and those with chronic Lyme disease.

How Does HHV-6 Work?

HHV-6 is known to attack specific cells including but not limited to CD 4 lymphocytes, NKTs,

oligodedrocytes, CD8 cells, and microglial cells. Moreover, this virus is immune suppressive and also

activates other viruses in the process. While HHV-6 can remain latent for long periods of time, it can

reactivate and cause infection quickly. The virus can lie in wait in the salivary glands, kidneys, or brain

until reactivated.

CFS, Fibromyalgia and Autoimmune

Disease Symptoms Linked to HHV-6

Maladies resultant of HHV-6 are many, and includes the idiopathic illness Chronic Fatigue Syndrome

(CFS). Patients who suffer with CFS potentially face immunologic abnormalities and neurologic

problems. It was observed in one study that 30 percent of CFS patients tested positive for HHV-6 and

after a series of follow-up tests, it was discovered that an additional 20-40 percent were also positive

after initially showing no trace of the virus. The obvious association between HHV-6 and CFS reaffirms a

much broader link between infection and chronic disease.HHV-6 is one of the infections found invirtually

all Chronic Lyme Disease patients a chief contributor to fatigue and other neurological symptoms.

Antibiotics do not affect this or other herpetic viruses.

HHV-6 as a Potential Causative to

Chronic Lyme Disease, Parkinsons, and

Alzheimers

Neurodegenerative diseases such as Alzheimer's, Parkinsons, and Multiple Sclerosis (MS) look

increasingly appear to be catalyzed by viral infections. More specifically, neurotropic virus HHV-6 has

been clinically shown to be tied to many neurologic problems including encephalitis, mesial temporal

lobe epilepsy, and many others.

Nevertheless, HHV-6s route into the central nervous system remains inconclusive. However, among

various brain regions examined, the highest frequency of HHV-6 DNA can be routinely identified in the

olfactory bulb/tract region. While further tests must be conducted, the olfactory pathway does seem

likely as at least one pathway for HHV-6 to move into the CNS.

Acute Lymphoblastic Leukemia

In one case, a childs acute lymphoblastic leukemia came only two months after an HHV-6 infection was

detected.Evidence continues to mount that suggests viral infections could play a major causative role in

some childhood leukemia.

HHV-6 Attacks p53 giving rise to cancers

Protein p53 regulates the cell cycle and thereby serves as an invaluable tumor suppressor one that

plays a vital role in helping the body prevent cancer development and growth.

How does p53 work?

p53 snaps into action when it detects DNA damage. Typically low levels of the protein rise immediately,initiating protective measures by binding to sites in the genome and halting cell division until the

damage can be repaired. Should the damage have progressed too far for repair, p53 will trigger

apoptosis, or cell self-destruction, eradicating the problem swiftly and completely.

HHV-6 Viral Co-infection of Chronic

Lyme Disease: Immunity and Cancer

Implications

Regulatory influences in cell proliferation, studies show, can be altered definitively by viral infections.

HHV-6 is a common perpetrator for such significant and impactful changes drawing additional attention

from researchers across the globe.

Envitas Fully Engages Chronic Lyme

Disease Complex and Its Dangerous

HHV-6 Co-infectionEnvita clinical experience in testing chronic Lyme disease patients shows many have activated forms of

co-infection viruses such as HHV-6. That means that many Lyme sufferers are likely carriers of this

infection as well as others. Biofilm communities and immunodeficiencies could make HHV-6 and other

virus actively replicate.


4/4

Envita employs only the most advanced diagnostic tools to test for a variety of infections like HHV-6, and

examine whether it is a causative factor for other maladies, such as Chronic Fatigue Syndrome. We

utilize the most effective therapies from around the world to modulate and boost immune function in

patients suffering with HHV-6 or those who are immunocompromised and at risk of contracting it.
