What are Stealth Viruses?
Viruses are submicroscopic infectious agents that replicate inside
cells. Viral illnesses are normally controlled by the bodyís
immune system acting primarily through white blood cells called lymphocytes.
These cells recognize certain viral proteins that provide the antigens
targeted by specific lymphocytes, leading to an anti-viral inflammatory
response. Not all viral proteins, however, can function as antigens
for effective anti-viral immunity. Indeed, for many viruses, only
a very few proteins are involved in lymphocyte recognition of virally
infected cells. Loss of these critical antigenic proteins can allow
a virus to essentially go unrecognized by the cellular immune system.
When such viruses have managed to retain the capacity to damage cells,
they can potentially cause a persistent infection resulting in a prolonged
illness. The viral nature of such an illness is usually overlooked
because of the absence of overt inflammation. Atypically-structured
cell-damaging (cytopathic) viruses were initially identified in patients
with the chronic fatigue syndrome and in patients with more severe
neurological and neuropsychiatric illnesses. The term ìstealthî
was introduced to highlight their basic property of evading effective
immune recognition, and also because they had gone unrecognized by
the medical community.
Detection of Stealth Viruses
Stealth-adapted viruses can be most readily detected using specialized,
semi-quantitative, viral culture methods developed and refined over
the last decade. Using these procedures, stealth viruses will typically
induce a characteristic vacuolating cytopathic effect (CPE) in cultures
of human and animal-derived cells.
Stealth virus infected cultures can be distinguished from cultures
of conventional herpesviruses, adenoviruses, enteroviruses and retroviruses,
by the appearance and host range of the CPE, and also by using selective
immunological and molecular probe based assays, including polymerase
chain reaction (PCR) testing methods.
Cytopathic Effects
A common feature of the CPE-induced, stealth adapted viruses is marked
metabolic disruption. This is expressed as lipid accumulation, cytoplasmic
vacuolization, formation of aberrant protein and lipoprotein inclusions,
and abnormally shaped nuclei. Comparable foamy vacuolating cellular
changes with atypical inclusion-like structures can be seen in detailed
examination of brain and other tissues obtained from stealth virus
infected patients and from animals inoculated with these viruses.
Unlike infections caused by conventional cytopathic viruses, the actual
production of readily identifiable viral particles is uncommon. Seemingly,
the infected cells are metabolically impaired because various energy
and other resources are diverted towards an inefficient and unbalanced
synthesis of various virus coded components at the expense of normal
cellular functions. Severe defects in energy-generating metabolic
pathways are also apparent from the marked mitochondrial changes that
are prominent in electron micrographs of virus-infected cells.
Center for Complex Infections Diseases
Both clinical- and research-based studies on stealth-adapted viruses
have been undertaken at the Center for Complex Infectious Diseases
in Rosemead, California. CCID is a non-profit organization under the
National Heritage Foundation dedicated to understanding the nature,
origin, disease associations, modes of transmission, methods of diagnosis
and responses to therapy of stealth virus infections, and to the dissemination
such information to the medical and lay communities. Information regarding
CCID is available from the internet at www.ccid.org. Additional information
is available from www.EmergingWorlds.com..
The following sections provide a brief overview of some of the ongoing
research activities being conducted at CCID.
DNA Sequencing Studies
A stealth virus isolated from a patient with a chronic fatigue syndrome
like illness was originally noted to have limited DNA sequence homology
to human cytomegalovirus (CMV). As additional sequence data became
available, it became obvious that this virus was a derivative, not
of human CMV, but rather of an African green monkey simian CMV (SCMV).
Until the beginning of last year, these monkeys were routinely used
to produce live poliovirus vaccine.
Moreover, although not widely revealed, a joint Food and Drug Administration/Industry
study in 1972 indicated that control kidney cell cultures from all
12 African green monkeys tested grew out SCMV, and that most of these
isolates were not detectable using standard procedures.
Continued sequencing on the SCMV-derived stealth-adapted virus has
shown interesting changes compared to a typical CMV. Of special note
is the uneven representation of genes that encode various viral components.
As expected, the genes that code the proteins known to provide major
target antigens for anti-CMV cytotoxic T lymphocytes are either absent
or mutated. Other genes are overly represented, including genes that
code for various chemokines and for chemokine receptors. Interestingly,
one of the markedly amplified chemokine receptor coding genes found
in the stealth virus genome can also function as a receptor for HIV,
suggesting a possible potentiating role of stealth viruses in HIV
infected patients.
One set of amplified chemokine-coding genes detected in the stealth-adapted
virus is of cellular, rather than viral, origin.
Cellular genes can apparently be incorporated into stealth virus
genomes, presumably during viral replication.
The particular chemokine-coding cellular gene identified within the
prototype SCMV-derived stealth virus was probably assimilated as a
partially processed RNA molecule since it lacks the normal introns
present in cellular DNA. This implies that stealth virus DNA replication
is proceeding through RNA intermediates, and that it may, therefore,
be dependent upon reverse transcriptase, as could be provided by an
assimilated endogenous retroviruses. RNA to DNA replication is much
more prone to error than is DNA to DNA replication. This might explain
sequence variability between the three copies of the chemokine-coding
cell-derived gene that have so far been identified within the stealth
virus.
Chemokine receptor genes of both viral and cellular origins have been
implicated in the development of several types of malignancies. It
is somewhat worrisome, therefore, that the stealth adapted virus is
apparently employing this type of gene for its survival. On the other
hand, many therapeutic agents that appear to be of some benefit to
stealth virus infected patients are known to inhibit cheomkine production
and receptor activity.
Viteria
It has also been determined that stealth viruses have the ability
to acquire genetic sequences of bacterial and even fungal origin.
Normally, viruses that are infectious for human or animal cells (eukaryotic
cells) will not infect bacteria (prokaryotic cells). Stealth viruses
appear to have overcome this phylogenetic barrier. The term "viteria"
has been coined to define eukaryotic viruses that have acquired bacteria-derived
genetic sequences. The sources of the bacterial sequences include
microorganisms that are not known to grow intracellularly within eukaryotic
cells. This strongly suggests that stealth viruses become viteria
by infecting bacteria. Judging from the bacterial sequences so far
identified, genes have been captured from a wide variety of both gram
positive and gram negative bacteria. The linear arrangements of many
of the bacterial-derived sequences are quite different from any of
the known major bacteria, suggesting that an active ongoing selection
process may be occurring to assist in stealth virus propagation within
bacteria.
Genetically empowered bacteria, carrying potentially oncogenic stealth-adapted
viruses, could become a far more threatening biological weapons program
then ever envisioned by military planners. Bacterial sequences incorporated
within stealth-adapted viruses may help explain positive findings
in stealth virus infected patients in various tests for known bacteria,
including Borrelia burgdoferi (the cause of authentic Lyme disease),
mycoplasma (a suggested cause of CFS and Gulf war syndrome); chlamydia
(implicated in coronary artery disease and Alzheimerís disease),
etc. None of the commonly used assays for these bacteria actually
detect cultured organisms, but instead rely upon broadly reactive
molecular and/or serological testing that could as easily be explained
by the presence of viteria.
Clinical Conditions Associated with Stealth Virus Infections
Stealth-adapted viruses have been recovered from the blood, cerebrospinal
fluid, urine, throat swabs, breast milk, brain biopsies and tumor
samples from patients with various neurological, psychiatric, auto-immune,
allergic and neoplastic diseases. Examples of neurological illnesses
are autism, attention deficit and behavioral disorders in children;
depression, schizophrenia, amyotrophic lateral sclerosis, multiple
sclerosis, chronic fatigue and fibromyalgia in adults; and neurodegenerative
illnesses in the elderly. It is now known that the stealth viruses
can infect many organs, but that the brain is especially prone to
manifest the effects of even limited localized cellular damage. The
varying manifestations of a stealth virus encephalopathy is probably
heavily influenced by the timing of infection, regions of the brain
that are mostly involved, genetic predisposition to particular symptoms
and the additive pathology of any superimposed auto-immune component
triggered by the viral induced cellular damage. CCID's focus is away
from strict clinical categorization of stealth virus infected patients
into discrete neurological and neuropsychiatric illnesses. This viewpoint
has been supported by following individual patients over several years,
and also by the not uncommon occurrences of related, yet diverse,
illnesses occurring among other family members and even among household
pets. Community-wide outbreaks of stealth virus infections have also
been observed with individuals showing varying levels of severity
and duration of illness. Neither the reporting of otherwise unexplainable
deaths, nor the apparent ìdumbingî of a whole township,
as reflected in the excessive need for special education for its children,
appears to provide adequate Public Health motivation to confirm CCIDís
findings of stealth-adapted viruses.
Cancer can now be added to the list of potential stealth virus-associated
diseases. Positive stealth virus cultures have been seen in virtually
all of the multiple myeloma patients tested, and in several patients
presenting with other types of tumors. A previous history of a fatiguing
illness and clinical indications of impairments in normal brain functions
are suggestive of an underlying stealth adapted virus infection in
a cancer patient. It will be interesting to determine the effect of
stealth-virus suppressive therapy in such patients.
Infection Among Blood Donors
An indication of the probable prevalence of infection among apparently
healthy individuals has come from studies conducted on student blood
donors attending a college campus. Slightly less than 10% of the units
tested gave a positive result. As a requirement of the study, it was
not possible to determine the actual health status of these students.
Nor were efforts allowed to follow recipients of the stealth virus
positive blood units. Even if culture-positive individuals are presently
asymptomatic, this would not preclude their being at risk for subsequent
development of a stealth-virus associated illness. This concern is
underscored by the apparent capacity of stealth-adapted viruses to
capture, amplify and mutateî various additional genes of viral,
cellular and bacterial origins.
Role of Other Infectious Agents in Chronic Illnesses.
Much of the debate over a potential infectious cause for many of the
illnesses that are increasingly being seen within our society has
centered upon conventional microorganisms. Patient support groups
and their affiliating clinicians have championed alternative explanations
for these illnesses.
Human herpesvirus-6 (HHV-6), human herpesvirus-8 (HHV-8), enteroviruses
and parvoviruses feature among the viral causes for these illnesses,
while Borrelia burgdoferi, Mycoplasma incognitos and Ehlichiosis are
being promoted as the bacterial causes for a wide spectrum of illnesses.
As is the case for HHV-6 in CFS, HHV-8 in multiple myeloma, enterovirus
in ALS and Borrelia in chronic Lyme disease, when looked at critically,
the actual findings are generally inconsistent with a true etiological
relationship. None of these negative studies exclude the role atypically
structured microorganisms; indeed, if anything they strongly support
their presence. As alluded to above, stealth-adapted viruses can easily
be mistaken in diagnostic tests for conventional viral and bacterial
pathogens.
Additional complex associations between stealth adapted viruses and
conventional microorganisms may exist. For example, the lipid-laden
cells infected with a stealth virus appear especially favorable to
the growth of intracellular bacteria, including Borrelia, the causative
agent of Lyme disease.
CCID has demonstrated positive stealth virus cultures in blood samples
from over 90% of patients referred with a diagnosis of chronic Lyme
disease. Whether the patients are actually infected with Borrelia
remains unproven, but if so, their growth may be dependent upon an
accompanying stealth virus infection. Synergistic growth patterns
between stealth adapted viruses and the viruses present in several
live viral vaccine preparations, have also been observed.
The potential role of stealth virus encoded chemokine receptors
in the evolution and the present day expression of HIV, is also under
consideration.
Clinical Approach to the Diagnosis and Therapy of Stealth Adapted
Virus Infections (SAVI)
Diagnosis: A major challenge in providing medical care for stealth
virus infected patients is the multiple and diverse clinical manifestations
of the patientsí illnesses. Individual patients do not fit
comfortably into a single medical discipline, whether it is psychiatry,
neurology, rheumatology, endocrinology, hematology, or any other.
Imprecise diagnostic labels, such as CFS, fibromyalgia, depression,
attention deficit, etc., and even the better defined diagnostic labels,
such as schizophrenia, autism, ALS, multiple sclerosis, Alzheimerís
disease, etc., tend to obscure the complex multi-system nature of
the patientsí illnesses. Another difficulty is quantitating
the severity of disease processes that can vary widely over time,
and can be influenced by such non-specific factors as stress, environmental
exposures to chemicals, placebo effects, etc.
Disordered brain function can be anticipated in many stealth virus
infected patients. This can be documented using a detailed neurological
examination, with a focus on what are sometimes referred to as ìsoftî
neurological signs.
Ancillary, although expensive, tests such as SPECT scans, quantitative
EEG and formal neurocognitive evaluations, can help substantiate a
diagnosis of stealth adapted virus infection with encephalopathy.
Additional syndrome names can be applied depending on clinical and
laboratory findings.
Tabulation of symptoms using a detailed questionnaire can be helpful
in identifying clinical problems and in assessing therapy related
improvements.
Therapy: Until the existence of stealth viruses is
accepted by Public Health authorities, there will be no approved standard
of care in providing anti-viral treatments. Several suggestions can
be made, however, from what is currently known about the prototype
SCMV-derived stealth virus. Whether these suggestions are relevant
to atypical viruses cultured from other patients remains to be tested.
CCID is now reaching out to clinicians involved with the care of stealth
virus infected patients for assistance with these clinical trials.
Basically, it seems appropriate to undertake efforts to suppress stealth
virus activation and at the same time to support cellular metabolism,
especially mitochondria function. The remarkable expansion of chemokine
and chemokine-receptor related genes within the prototype SCMV-derived
stealth-adapted virus support the potential use of agents that can
down regulate chemokine pathways. Fortunately, many of the widely
used herbal and generally non-toxic allopathic medicines are known
to interfere with chemokine signaling. It is probably more than a
coincidence that many of the compounds have also been reported to
benefit at least a proportion of patients with CFS and related illnesses.
Ideally, patients receiving these relatively simple therapies would
be retested for stealth virus activity. If there were no apparent
reduction in stealth virus activity, and if the patient remained symptomatic,
one could more easily justify the use of potentially more toxic allopathic
medicines, including known anti herpesviral agents.
For patients with major neurological, psychiatric, autoimmune or malignant
diseases, the stealth virus associated treatments will simply be an
aside to the accepted standard care of the patientís underlying
illness. Once sufficient supportive data are collected, it may be
possible to proceed directly with anti-stealth virus therapy as the
primary treatment for these severe disorders.
Request for Assistance with Clinical Therapeutic Studies. In support
of these studies, CCID has begun to work with medical specialists
treating major medical neurological, psychiatric, rheumatological
and neoplastic illnesses, and also with orthomolecular clinicians
experienced in the uses of alternative medicines. Stealth virus culture
activity will be serially determined and correlated with the use of
various therapeutic modalities and changes in clinical status. CCID
can provide copies of patient questionnaires and an appropriate informed
consent form. A database for integrating laboratory, clinical
and pharmaceutical data, will be established and will be assessable
to all participating clinicians. The type of program is urgently needed
to address the major Public Health threat posed by stealth-adapted
viruses and viteria.
Additional information and copies of various research publications
on stealth viruses, requisition forms, etc, can be viewed at
http://www.ccid.org. Clinicians wishing to participate in stealth
virus research should contact CCID. Stealth virus testing requires
an Acid Citrate Dextrose (ACD) yellow-topped tube of whole blood.
While a $250.00 fee is required for an initial diagnostic assay, a
subsequent test on the patient during or following therapy will be
at no charge.
Blood samples should be sent via Federal Express to CCID, accompanied
by a physician request for testing. CCID is located at 3328 Stevens
