TREATMENT OPTIONS FOR
GENITAL AND ORAL HERPESVIRUS INFECTIONS
by Dr. H, MD
Updated December, 2017
If one looks back into the medical literature, many different treatment
recommendations can be found for herpes infections (HI) going back many decades. Prior to the
arrival of effective anti-viral compounds, treatment options included such
diverse concepts as topical application of deoxyglucose or the surgical
removal of infected areas. The former ultimately was proved to be ineffective,
and the latter resulted in individuals having viral recurrences along the
surgical scar. Neither, of course, are recommended by anyone today.
The message, though, is that desperate people who are suffering will
often jump at offers of "cures" from various medical and quasi-medical
solutions which have not been substantially examined by peer-reviewed research.
The results of these "solutions" in fact may include increased suffering
by the victim and a worsened public health outcome both for the victim
and the victim’s consorts.
The author respectfully requests
that the reader take a few minutes and review this paper. The reader will
find a broad, readable discussion about the current recommended treatments
for HI. After reading this discussion, hopefully the appropriate treatment(s)
for the condition will become apparent.
Herpes is a virus that infects the nervous system, modifying the DNA
of the nerve cells supplying the skin through which the virus entered.
The infection is permanent. Most patients suffer from recurrences that
may vary in frequency from once in a lifetime to non-stop infections that
never go away. The average rate of recurrences is about four times per
year, plus or minus one or two, with some variation of recurrence rate by gender. Recurrences typically take about a week or so
to heal. This means that the average untreated person with HI spends about
a month out of the year with lesions.
Another fact about having an infected nerve cell is that the cell may
be making viral particles at any time, perhaps most of the time. The signs
of recurrence on the skin apparently are related to the production of a
large amount of viral particles. Probably when the nerve cell makes fewer
viral particles, the skin may not show signs. Put another way, the nerve
cell may be actively producing viral particles even though the skin has
no rash or redness. This condition is called "asymptomatic viral shedding".
The general consensus is that any person with HI who does not have any
symptoms currently in fact is shedding virus about 4% of the time. Put
another way, an asymptomatic person with HI has a 1 in 25 chance of being
contagious at any given time. This is true assuming of course that the
person is not on medications (see below). Current research in female patients
puts the asymptomatic viral shedding rate in genital Herpes infections
(GHI) even higher in one published study.
The problem with HI, therefore, is that a piece of viral DNA resides
permanently in a nerve cell . This viral DNA is periodically copied and
turned into viral particles that may generate contagious viral shedding
or cause a contagious rash. It is through interfering with the process
of the formation of viral particles where the opportunity comes to "treat"
the problem and prevent the spread of these particles to non-infected patients.
The mainstay of treatment is in the identification of the illness and
forming a rational plan to manage the condition. Evidence exists that patients
"auto-inoculate" themselves. In this condition, the patient makes him/herself
worse, either through the spreading of the infection on the skin to adjacent
skin areas OR actual spread from nerve cell to nerve cell in the area where
the nerve cell lives beside the spinal cord (called the ganglion). The
former occurs in part when the untreated rash is allowed to remain undrained and
uncleaned. The latter probably occurs at various time, including when the
patient has symptoms and does not take medication to terminate the symptoms.
The first point of care then is that a person with symptoms needs a
diagnosis. Any person with an oral or genital/rectal rash, especially associated
with blisters, pain, or pain referred into the buttocks or legs, should
be seen and evaluated by a physician or other trained medical professional
skilled in the evaluation and management of HI. A viral culture should
be taken of a lesion at some point in the person’s medical history to attempt
to identify the organism. The patient’s consort should be counseled and
possibly evaluated along with the patient.
Blood tests to establish diagnosis of HI are not always very helpful.
The only REAL way to document that a patient has suddenly developed HI
from a blood test is to draw blood quickly after the onset of symptoms
and to document that the patient’s blood test is negative. Then 4 to 6 weeks later a second blood test is drawn to document that the patient
has suddenly developed antibody against the virus. Even then, these tests
are not completely reliable and often do not give clear and concise answers.
Smart living prevents infections. It is clear from various studies that
educated patients and educated consorts can drastically reduce the transmission
of infections. While it has been shown in earlier studies that consorts
do often become infected, it is also clear that the use of anti-viral medications
(see below) decreases both recurrence frequency and viral shedding. Medication
combined with smart living and use of condoms can drastically lower disease transmission.
This is not a guarantee, of course, but it does offer some reassurance
that in the symptom-free patient who is taking medications as directed
and using a latex condom, the risk of transmission is very, very low,
possibly as low as one chance in a thousand per exposure.
The combination of smart living with anti-viral medications (in patients
for whom these medications work) can potentially create a vast public health
improvement affecting literally millions of individuals.
Anti-Viral Medications
About twenty years ago it was noticed that certain viral infections
could be treated through the use of chemicals that are part of DNA. Specifically,
modified "bases" could be applied topically (on the outside of the body)
in the setting of virus infections in the eye, for example, that could
improve the infection. Soon to follow was the use of a modified "guanosine",
called acyclovir, as a cream to be applied onto HI lesions, which produced
some modest improvement in symptoms. The rash would clear up a couple of
days quicker than if no cream were used. Recurrence frequency was not affected.
About 15 years ago acyclovir became available for oral use. Studies
rapidly appeared indicating that the medication was not only safe but highly
effective. When taken as directed, patients’ symptoms of both acute infections
and recurrences rapidly improved. When the medication was taken ONLY for
recurrences, little influence was found upon recurrence frequency.
About 10 years ago it was found that acyclovir, when taken on a daily
basis, could decrease recurrence frequency to about once per year. Also,
it was found that when a recurrence DID occur, it was milder and of shorter
duration. Further, recent studies have indicated that asymptomatic viral
shedding was reduced as much as 80% in patients who took acyclovir regularly.
How does Acyclovir work? Its actual effect in killing virus has not
been definitely proved. Acyclovir has several actions in the test tube.
It inhibits the enzymes that copy viral DNA, and it also inhibits the replication
of virus. Also, again in the test tube, acyclovir is taken up into the
growing chains of viral DNA, causing termination of these chains. Acyclovir
seems to be "selectively" taken up by infected cells. Acyclovir is much
less toxic for normal cells because less is drug is taken up, less is converted
to active form, and normal cell enzymes are less sensitive to the chemical
(to paraphrase the PDR online).
The problem with acyclovir is this: It doesn't stay in the body very long, and when taken by mouth, its blood levels are fairly low. A modification of the acyclovir molecule, called valacyclovir, gives higher blood levels. As a matter of fact, valacyclovir is able to achieve blood levels almost equivalent to the intravenous administration of acyclovir.
The use of any anti-infective chemical can be associated with increasing
the occurrence of resistant organisms. Certainly this is also true in the
case of acyclovir for HI. Resistant organisms have occurred, in some cases
requiring multiple anti-viral medications to control symptoms. Interestingly,
one study suggested that allowing break periods in the administration of
acyclovir allowed sensitivity to the drug to return. This technique is
speculative and not currently recommended.
That being said, however, HI resistance to acyclovir and the other antiviral medications is relatively rare. Specifically, the percentage of cases of acyclovir resistance seems to be stable at about 0.3% of all persons with herpes infections. This means that 99.7% of people with herpes infections carry viruses that are sensitive to acyclovir, and this is great news for almost everyone that has a herpes infection. If outbreaks occur, then if acyclovir is taken (or the other antivirals such as famciclovir or valacyclovir), almost certainly the outbreak will come under control.
Almost all patients can control symptoms through Smart Living concepts along with medication. The medication is very well tolerated and has few side effects.
How much medication is enough? For acute episodes the recommended dosage of acyclovir is 200 mg taken five times per day for approximately ten days, possibly
longer. This author’s clinical experience indicates that 400 mg taken two or three
times daily is probably equally effective.
The dosage of valacyclovir is 500 to 1000 mg daily for outbreaks. This medication can be taken once or twice daily, which is more convenient for most people. The duration of the therapy is the same as for acyclovir. The cost of the brand product of valacyclovir is much higher than generic acyclovir, so the consumer will have to weigh if an additional benefit is brought by the additional cost.
Therapy for recurrences can be performed in two ways: Episodic therapy,
and chronic suppressive therapy. In the first, the patient takes about
400 mg of acyclovir two or three times per day (whichever level it takes
to reduce symptoms) for about a week or ten days. The dosage of valacyclovir is 500 to 1000 mg once or twice daily, depending on the responsiveness of the patient. Most patients will promptly clear their symptoms on this level of medication. Depending on the patient’s "disease level", either the condition will go away for an indefinite period OR the patient will then have another recurrence once off the medication.
Patients who seem to have regular recurrences in spite of Smart Living
and/or in spite of episodic therapy are candidates for chronic suppressive
therapy. In this treatment method, the patient will take a daily dosage
of acyclovir or valacyclovir either once or twice daily. The dosage per pill will be 200 mg to 800 mg for acyclovir and 500 mg to 1000 mg for valacyclovir. The minimal dosage that will control symptoms is the dosage that should be taken. Given this treatment method, recurrences in almost all patients can be reduced to once or twice per year, and the recurrences that occur will be milder. One should also remember that asymptomatic shedding will be substantially reduced on chronic suppressive therapy, which should reduce how contagious a person with GHI will be.
Famvir, a drug similar to acyclovir (penciclovir), theoretically,
would seem to offer some advantage for therapy because of the increased presence of the medication within the cell, due to the manner in which the medication
is phosphorylated. One would think that a medication which is more rapidly
absorbed AND which persists longer inside the target area would in fact
give a substantially improved effect. At this point, this does not seem
to be the case based upon readily available patient treatment data.
How long can a patient safely be on acyclovir or other antivirals.? Two papers (Baker from Stony Brook and Goldberg from Baylor, possibly reporting the same data)
report a study going out five years. No side effects were reported in the
abstracts, and viral resistance to acyclovir was "not observed". Recurrences
were diminished from a mean of about 13 recurrences per year to less than
one, a reduction of 92%. They found that the recurrence frequency continued
to be reduced into the third year on medication, and beyond that no further reduction
in recurrence frequency was noted. In this study the dose of acyclovir
was 400mg twice daily. The reader is referred to the quoted New England
Journal article above suggesting that the patient should tailor the dosage
to the minimum needed to "control symptoms".
Studies going out nearly a decade of patients on continuous acyclovir therapy continue to reveal the safety of antiviral medications for herpes infections when taken daily for many years. No toxicity was reported in these studies, nor was there an increase in viral resistance to the medication.
How should a patient actually take the medication when on suppressive
therapy? This author suggests placing the dosage alongside a patient’s
daily vitamins: Vitamins C, E, B complex, selenium (for males), and tomato juice (especially for males because of the lycopene) are suggested.
(One might also consider taking dosages of atragalus, echinacea, and possibly
red marine algae. These three have had various articles suggesting immune system
benefits that could possibly reduce recurrence frequency, though the results of these studies are less clear). In this manner
the prescription medication will not be forgotten.
What should a person on suppressive therapy do if an outbreak occurs?
First, the patient should not panic. This happens, and this almost always
does not mean that the patient is developing viral resistance. It simply
means, apparently, that whatever trigger in the nerve cell is at work to
initiate viral DNA transcription and replication is suddenly overwhelming
the amount of Valtrex or acyclovir that is on board. One need only increase the dose of valacyclovir to 1000 mg daily (or 500 mg twice daily) or acyclovir to probably 400 mg three times daily (or, 200 mg five times
daily), and the recurrence should begin to subside relatively soon, anywhere
from one to a few days. The recurrence while on medication is typically
milder and of shorter duration. After the lesions have formed dry scabs
and the skin redness has subsided, the patient can usually go back to the
original suppressive dosage once or twice daily.
A brief word would be in order about the development of viral resistance.
A number of strains of HSV which are resistant to acyclovir, valacyclovir, and
Famvir have been discovered. In the overall population resistant strains
are relatively rare, though in immunocompromised patients, such as those
in the later stages of HIV infection, resistant strains are somewhat more
common.
Where does viral resistance come from, given that the viral DNA information
is apparently incorporated into human DNA? Resistance, apparently, comes
when virus particles are released from infected cells that no longer have
the enzyme necessary to activate acyclovir. The virus particles, interestingly,
have to convert the acyclovir to a chemical that kills themselves. Apparently
they get smart and learn how to do without the enzyme that converts acyclovir
into something that kills the virus. Again, the development of a recurrence
while on suppressive therapy does NOT mean that the patient is harboring
a resistant strain. Consistent inability to suppress acute infections with
acyclovir is worrisome, however, and should be further evaluated. Tests
for viral resistance ARE available but are generally found in centers that
do research on such subjects.
Let us leave the discussion of acyclovir and the other antiviral medications on a positive note. Utilizing once or twice daily suppressive therapy, almost all victims of this illness can dramatically decrease the
incidence and severity of recurrences. Also, the patients and their
consorts can take comfort in knowing that the incidence of aymptomatic
viral shedding is likely reduced as well. This does not decrease the need
to take appropriate precautions (see Smart Living). However, at
least the risk of transmission is apparently substantially reduced. Also,
regular use of the medication has been shown in the literature to CONTINUE
to reduce the incidence of recurrences through the first three years of
therapy, as mentioned above, a benefit that has also been shown to persist
for at least two or three more years of therapy.
Medical therapy for GHI and to some degree OHI can dramatically improve
the enjoyment of disease-free intervals, at the same time reducing the
risk of shedding the virus and probably making disease transmission less
likely. This dramatic improvement of symptoms through the use of a now
inexpensive and essentially non-toxic chemical, when used as directed along
with appropriate Smart Living techniques, promises to offer a major
improvement of life enjoyment for the Herpes sufferer and his/her consort
and improvement of the general public health as well for many years to come.
Non-prescription Therapies for Herpes Infections:
I have read extensively about possibilities that may come about with the use of Opuntia cactus. If a reader of this paper is interested in the use of Opuntia for the treatment of herpes, I would ask that reader to please contact me at the website and let me know so that I can assist in helping the reader find a source of it.
Interestingly, one recent paper indicated that the application of red wine to the lesion (topically, not consumed) actually will assist in aborting an outbreak.
I found another interesting series of papers recently on the use of Tagamet (generically it is called "cimetidine") for the treatment of herpes infections in animals. It turns out that cimetidine has "immunomodulation" effects, meaning specifically that it depresses the activity of "T suppressor cells" which may be inhibiting the body's natural cellular mediated immunity which is known to fight off recurrences. The interested reader can to go The National Library of Medicine and perform a search on "herpes" and "cimetidine" to read these articles. The reader might print these off and take them to the private physician for discussion. I do NOT recommend this therapy to anyone until more research is performed in this area. Someone who is immunosupressed already, such as with HIV or cancer, would want to particularly avoid such a treatment.
Future Medical Therapies for Herpes Infections:
New antiviral medications are constantly being researched. A recent
Japanese paper reviewed research on dozens of new chemicals which suppress
Herpes virus formation, including resistant viruses. Periodically new chemicals
are produced that offer new approaches to treating recurrent disease. Some
chemicals, like cidofovir, can be toxic to certain human cells, such as the
kidneys, though are very effective at controlling herpes virus infection.
The reader must remember, though, that it takes many years from the time
of the identification of a chemical that seems to work until the release
of the drug on the market that has been exhaustively determined to be "safe
and effective".
The reader should review the adjacent paper on the current status and
the future of herpes vaccines. At some future time the use of the body’s
immune system MAY in fact be the most "safe and effective" method to control
infection. Literally hundreds of published articles concerning many human
and animal studies indicate that already methods exist to modestly, and
sometimes substantially, alter the course of disease and offer prevention
in some cases. However, the safety and efficacy of such vaccines have not
been clearly proved in the world’s literature at this time.
This author was previously excited about the concepts of the "disabled infectious
single cycle" vaccines and the DNA vaccine technology that might have offered exciting prospects for confronting both GHI and
OHI and both controlling the spread of these diseases as well as controlling
symptoms in infected patients. Sadly, the research did not indicate a positive benefit for all participants in the trial.
Another exciting area is in that of an evolving therapy for women that may both treat women as well as possibly offer protection for intimate partners. This falls into the area of "Intravaginal Release" of medications. European research is ongoing in this area, and we may soon see a new route of prevention and treatment available in this manner.
The cells that are infected can be localized. This is
obviously true because of the skin location where recurrences occur. The
infected cells transmit viral particles to the skin. This means that the
skin identifies the infected cells. This WOULD be a conduit directly to
the infected neurons, were there to be some medication that would permanently
affect the involved cells and render then non-infectious or even dormant.
A risk would be generated, of course, in killing the infected cells. These
nerve cells are involved with sensation to the skin and possibly important
reflex arcs and other important nervous system functions. Current research is ongoing in this area, with the possibility of direct DNA therapy to the infected cells being explored (see CytoGenix's work HERE. Clearly though
this concept remains an area for future treatment considerations.
