Ebola Treatment Protocol Questioned
“THERE IS NO TREATMENT, THERE IS NO CURE”…well, that is not entirely true.
The heroic organization Medecins
Sans Frontieres (MSF) and the physicians at other Ebola treatment units (ETUs) in
West Africa provide a minimal form of treatment called “supportive care” for
patients with Ebola virus disease (EVD). This includes keeping patients
hydrated with water containing electrolytes, giving antibiotic drugs to help
prevent secondary infections, painkillers and antimalarial drugs. This
increases an Ebola patient’s chance of survival from only 10% in the absence of
such care, to an average of 45%. But basic supportive care does not include any
drug therapy targeted directly at the virus itself – no antiviral medication.
Two
days after I arrived in Monrovia, Liberia from South Africa for the second time
during the 2014 Ebola crisis, I attended the “Treatment Protocol Review”
meeting at the Corina Hotel on Tuesday, November 11th.
Approximately fifty health
professionals attended this Ebola protocol review. They represented various
government and non-government organizations including the National Institutes
of Health (NIH), the Center for Disease Control (CDC), the US Agency for
International Development (USAID), the US Army, the Food and Drug
Administration (FDA), the US Public Health Service, the World Health
Organization (WHO) and the Liberian Ministry of Health (MoH). About half those attending
were from the United States and approximately ten percent were Liberian. The
remainder were Africans or Europeans representing various international health
NGOs. Dr Moses Massaquoi, country director for the Clinton Health Access Initiative
and head of Ebola case management at the Liberian MoH co-chaired the meeting,
along with a young Indian doctor from the NIH.
The group met briefly as a whole, then divided into five working groups to discuss their assigned topics. The five working groups were: 1) clinical guidelines (general and co-morbidity) 2) special populations (children, pregnant women, breastfeeding, etc.) 3) nutrition 4) psychosocial, and 5) experimental and non-traditional therapies. After morning and afternoon sessions, the groups merged to listen to and comment on the various working group reports.
As
Dr Massaquoi expected, I joined group five expecting to discuss experimental
and non-traditional therapies. There were nine members in our group, medical
and health bureaucrats, most with MD and PhD degrees that I lacked. Given its
designation I thought group five would examine what possible therapies should
be considered to be tested against Ebola and the pros and cons of those potential
treatments. We could prioritize what therapies should be fast tracked for
testing and eliminate suggestions for some proposed remedies like nano-silver
or herbal concoctions. Those had little scientific merit and no probability
that they would be effective against a virus as aggressive as Ebola. Since the
doctors I had been working with at the Ministry of Health had already conducted
a successful trial using the selenium I had brought them at their request on my
first trip from South Africa, naturally I thought I might be given five minutes
to make a brief presentation. Our informal clinical trial conducted at ELWA
Hospital, Monrovia in August had demonstrated selenium’s ability to reduce mortality
by almost 54% from current levels, even using a suboptimal dose.
Surprisingly,
in the seven hour meeting, no one ever even mentioned discussing various
potential therapies for Ebola. Instead, the only subject group five discussed
was how to regulate and restrict testing and how to stop the use of whatever was
currently being tested or used against Ebola that was not already included in
the standard protocol. It did not matter how successful the results that had
been obtained may have been. Group five recommended that all current testing of
experimental therapies should be stopped as soon as possible. Thus, no
medication should be given at any ETU after December 1 unless it was already an
approved part of the current treatment protocol as of the date of the Corina protocol
meeting. As someone suggested. that would be, “under penalty of the law” – even
though the assembled group had no legal standing in Liberia. The group decided
that any medication must undergo protocol approval before it is tested. That
sounded reasonable, although it would make it much more difficult to conduct ad hoc informal trials by anyone lacking
major financial backing. According to these recommendations, any ETU that gave
selenium or lamivudine or anything else not included in the current protocol to
patients after the first of December, those doctors should be subject to
arrest. This allowed all therapies that were already part of the established
treatment protocol to be used even though none of them had previously undergone
controlled clinical trials against Ebola. It was clear that selenium and the
anti-HIV drug lamivudine were the targets of this meeting because they were the
only two therapies listed on the power-point slide that had been prepared prior
to the meeting. The Treatment Protocol Review was obviously a formality to
cement the door shut on the use of the only two therapies that had shown
significant benefit to patients in the epidemic so far.
As the group five discussion
progressed the young officer representing the US military seemed particularly
enthusiastic in coming up with new restrictions to testing potential therapies.
In his notebook he quickly drew up a list of at least five different ways to
restrict research. Clearly he had prepared for this meeting. The officer even
suggested that nothing should be tested in a clinical trial unless it had
already been analyzed in the test tube and had shown anti-viral activity
against Ebola. This would make it almost impossible to test anything first in
Liberia. It would also eliminate the possibility of trying immunologically
based mechanisms to treat EVD. Perhaps that officer had been working on the
$147 million program the Army had invested in to develop Ebola medicines and
wanted to protect that drug’s exclusivity. Regardless of the newly proposed requirements,
ironically none of the “supportive care” therapies that were currently being
used to treat Ebola had undergone clinical testing or rigorous analysis against
EVD. According to the recommendations of group five, these therapies were all now
exempt. The fix was in. The rules had changed.
As the discussion dragged on it was
easy to see the deck was being stacked against any novel intelligent medical innovation
during this crisis. Although I
distributed scientific journal extracts about selenium and hemorrhagic fever
virus diseases to the other eight group members, I never demanded to present my
information because that seemed the opposite of everyone else’s agenda. I spoke
up to make points several times but nothing I could say or present would have influenced
a meeting intent on shutting down a more open process of investigating potential
treatments and conducting informal research on EVD. Sitting on the opposite side of the group
circle, the FDA representative glared intensely at me as if I were the real enemy,
not the virus. Although I had handed him the scientific information about
selenium and its historic success in treating hemorrhagic fever viruses, he was
the only person who left the hand-outs on the table, refusing to even
acknowledge them. Closed minds need no more information – scientific or
otherwise
Although the issue was not raised in
this meeting, another foreign doctor in Liberia had suggested that selenium
should not be used on Ebola patients unless or until its efficacy against Ebola
had been reported in a peer reviewed medical journal. In this deadly crisis
situation that was like putting the cart before the horse. Even if a clinical trial
of selenium was fully funded and showed great success, this stipulation would
delay its use for months. His suggestion disregarded the fact that selenium’s
benefits against hemorrhagic fever disease had already been published in peer
reviewed medical journals. The articles included reports that selenium had been
shown to be effective in reducing mortality rates in both Marburg and Hantan
hemorrhagic fever epidemics by approximately 60%. None of the drugs being used
to treat Ebola had proved as effective as that. So this meeting had been called
to establish a double standard. The Corina Hotel protocol review revealed that behind
the scenes there was a full-scale effort to immediately stop Liberia from independently
testing anything that might save the lives of Liberians infected by this disease.
Accepting that agenda would slow down progress in finding effective treatments
for EVD since it would limit research to investigating only new experimental
drugs for the benefit of the pharmaceutical industry. Who would fund a trial of
an inexpensive medication like selenium with no profit motive as an incentive?
Even if fast tracked, new experimental drug investigation would take months, even
years before effective therapies could slog through the lengthy process of
testing and approval, and then be manufactured in the quantities needed.
Logically, one must question why international “experts” are treating a
viral disease with antibiotics instead of trying dugs with proven antiviral
activity. All Ebola patients were being given broad spectrum antibiotics to
prevent secondary bacterial infections. Yet none of them were being given
antiviral drugs to try to slow down the virus that was causing the problem.
Doctors were treating symptoms and trying to prevent potential infections but
not attacking the cause or the mechanisms of the disease. If this were a newly emerging
bacterial disease, doctors would immediately try a number of existing
anti-bacterial drugs to see if any might work. Then why would international
health authorities apparently refuse to try, even block testing existing anti-viral
medications against EVD? Just like in HIV/Aids, Ebola infects and attacks the
immune system causing immune deficiency leading to secondary bacterial infections
that need to be controlled with antibiotics. But that is not an excuse for not
attempting to attack the cause of this disease, the virus itself. Testing the
arsenal of over two dozen antiviral drugs that are currently sitting on
pharmacy shelves might quickly uncover several that would be more or less
effective. Most of the instant pop-up experts who had descended on West Africa
and the Cornia Hotel protocol review meeting were not Ebola experts at all.
Most were not even acquainted with the underlying scientific mechanisms of the disease.
Dr Armand Sprecher heads MSF’s heroic efforts against
Ebola in West Africa. No organization has worked more diligently and valiantly
against this epidemic than Medecins Sans Frontieres. Dr Sprecher did not attend
the Corina meeting. However when I talked with him previously in August at the
Ministry of Health he told me he had been fighting Ebola outbreaks for fifteen
years but was not aware that anything could treat Ebola. I was amazed he did
not know about selenium’s effect against hemorrhagic fever diseases.
As an Aids researcher my analysis of
Ebola virus disease comes from a different historic perspective. I had
twenty-five years experience researching HIV disease and fifteen researching
selenium, reviewing a thousand medical journal articles copied from the UCLA
and USC medical school libraries in Los Angeles. I have spent a dozen years in
Africa selling selenium to medical clinics and pharmacies and talking with
doctors and pharmacists about the results they observed in their patients. I
designed several HIV clinical trial protocols for doctors to implement in
Africa and have attended over twenty international Aids conferences on five
continents. During those years I came across several medical journal articles
that reported that 2.0 mg of selenium in the form of sodium selenite could successfully
treat viral hemorrhagic fever outbreaks. Each time, this therapy resulted in
60% reductions in mortality. However if a medical paradigm purports to be true
and it is repeatedly drilled it into doctors’ heads that “there is no treatment
and there is no cure for Ebola”, this becomes the accepted dogma. Most
physicians close the book on even the possibility of testing potentially
beneficial existing treatments.
Dr Jerry Brown at ELWA Hospital who was named “person
of the year” on the cover of Time magazine for 2014 tested the selenium
tablets I brought to the Ministry of Health in early August 2014. Although he
used a lower dose than I had recommended – 1.2 mg instead of 2.0 mg - he
demonstrated a 54.5% increase in survival rates - from a 44% survival rate just
prior to providing selenium to 68% with the new tablets. . Still, MSF refused
to use selenium supplements on their patients. Their static treatment paradigm
could not be reconciled with the fact that selenium actually works and saves
lives of Ebola victims – a lot of lives. Paralyzed by the repeated medical
mantra that nothing can possibly work against Ebola, their minds were closed,
much to the detriment of their suffering patients. The Corina Hotel treatment protocol
review was designed to keep them all closed by eliminating the possibility of
innovative approaches to treatment.
Selenium works against Ebola through
multiple immunological mechanisms. Ibuprofen, aspirin and the
aspirin-derivative drug asacol (5-ASA) also work as broad spectrum antiviral
medications through a single mechanism. These non-steroidal anti-inflammatory
drugs (NSAIDs) reduce viral replication in the nucleus of cells by inhibiting
the cellular protein NF-kB (nuclear factor-kappa
binding). Almost all viruses utilize this critical human protein, called a
replication factor, to stimulate their own reproduction. Therefore NF-kB
inhibitor drugs (NF-kBIs) work as broad spectrum anti-viral agents. The medical
profession prefers to ignore this well-established science because it conflicts
with the maximum profit motivation of the pharmaceutical industry. Their
rationale is that if you do not need a prescription for a medication, then we
won’t tell you about it. Most physicians are not familiar with NF-kappaB inhibitors, or the immunological
effects of selenium, because this is not taught in medical school.
After the protocol review meeting adjourned, the NIH
co-chair of the meeting and I briefly discussed NF-kappaB. He indicated he either did not know or refused to
acknowledge that NF-kB stimulates viral replication nor that NF-kB inhibitors
would reduce viral replication. He asked me if I knew that NF-kB was in the
human cell, the most basic fact anyone could know about it. In fact during the
1990s I read more than one hundred scientific papers on the newly prominent
NF-kB protein. Nobel laureate Dr David Baltimore discovered this central actor in
cellular and immune function – and viral replication - in 1986. As an
intellectual exercise in the late-1990s I wrote an eight page scientific paper
on NF-kB with over sixty medical journal references. The fact that NF-kB
inhibitors are not used against Ebola and HIV is tragic. Health suffers and people
die unnecessarily. While NF-kB inhibitors are certainly not the strongest class
of antiviral drugs, they do reduce both viral replication and the impact of
most viral diseases.
What the NIH, the WHO and others either
do not understand or acknowledge – that NF-KB inhibitors like aspirin/asacol,
ibuprofen and selenium are broad spectrum antivirals - hurts people with Ebola
as well as those living with HIV. Refusing to even test proven ways to reduce
viral replication and reduce hemorrhagic fever mortality threatens not only
West Africa, but potentially the entire world. While NF-kappaB inhibitors like aspirin and ibuprofen hold promise in
treating Ebola that is no guarantee they will be highly effective. They need to
be tested to determine their exact level of efficacy. Selenium has already been
tested, retested, and found to be moderately to highly effective against
hemorrhagic fever. In August 2014 it was tested against the specific strain of
Ebola in this epidemic, Ebola-Zaire. In the past it has worked against other
hemorrhagic fever viruses every time, providing a 50% or greater reduction in
mortality when the correct dosage was used. Selenium supplementation hits at the
very essence of this disease, the depletion of the immune protective element
selenium by the Ebola virus. Selenium supplements work via multiple mechanisms
reducing symptoms, as an antiviral, and by helping protect the immune system
from the onslaught of Ebola. Other NF-kB inhibitors like NSAIDs are beneficial
against both the virus and some of its symptoms. But no NSAID packs the powerful
punch of selenium.
At the protocol review meeting the
nutrition committee also did its best to supress the use of selenium. Its
report suggested no one with Ebola should receive more than the RDA – the
recommended minimum daily allowance
of selenium – 60 mcg. That RDA for selenium is based on the minimum amount
required at the cellular level to produce adequate glutathione peroxidase, the
universal antioxidant that helps keep every cell in the body healthy. But 60 mcg
is the minimum needed for a normal healthy
person. The average American diet contains approximately 150 mcg selenium a
day. However a sick person needs much more than that since viral and bacterial
infections rapidly deplete selenium levels in the body. Selenium supplements
benefit patients because just like most cells in nature, bacteria and most viruses
need selenium in order to exist, so they steal it from the body. Microorganisms
also attack the body’s selenium supply as a way to weaken the body’s immune
defences against them. The nutrition committee’s recommendation reflected a
great ignorance of the fundamental mechanisms of EVD. They were merely echoing
the predetermined but unspoken agenda of the meeting – to shut selenium and
lamivudine down.
Many diets in
the world are low in selenium. Some Scandinavian countries supplement selenium
into their agricultural soil due to its anti-cancer properties. The average
Liberian diet is almost certainly selenium deficient. In Zambia, a country with
a similar diet, 50% of the population does not receive the minimum RDA of
selenium. While the selenium poor diet predisposed Liberian patients towards
negative outcomes, selenium rich diets contributed to better outcomes for the
American doctors who were infected.
Another disturbing thing brought up
at the protocol meeting was that 100% of Ebola patients are given anti-malarial
drugs. Have antimalarial drugs been tested in controlled clinical trials to see
if they are beneficial in Ebola infection? The science suggests these drugs may
be dangerous in this circumstance. During the group five discussion the doctor
from Sweden erupted when I suggested that not every Ebola patient should be given
antimalarial treatments. He questioned whether I knew that everyone in the
region has malaria. I did know malaria was endemic and chronic, but people only
suffer active malaria one or two weeks a year and not every year at that. On
the other hand, apparently the doctor was completely unaware that the
immunological action of antimalarial drugs directly increases viral replication
and could contribute to EVD progression and death.
Antimalarial drugs attack malaria
parasites by massively increasing oxidation in the red blood cells malaria
infects. This massive increase in oxidation kills the malaria parasite but it
increases the release of NF-kB by orders of magnitude. NF-kB is the primary
stimulant to viral replication in the nucleus of cells where viral particles
are produced. [To understand this better read my peer reviewed, published
scientific paper found on this website, “Taking the HIV Factory Tour”.] Theoretically,
anti-malarial drugs should significantly increase Ebola replication, putting
patients at greater risk. While anti-malarial drugs cause hyper-oxidation to
kill malaria parasites, the Ebola virus also causes hyper-oxidation (peroxidation)
that damages blood vessels. That is what eventually causes hemorrhaging in
about one percent of cases in the terminal stage of EVD. Thus using
antimalarial drugs on 100% of Ebola patients is most likely doing much more
harm than good. Should the use of antimalarial drugs be banned from Ebola
treatment until they have undergone controlled trials? That would be a wise
precaution. At a minimum EVD patients should be tested for malaria before they
are given antimalarial drugs and only patients with active malaria should be
given them. Once again this shows the newly minted Ebola protocol “experts”
have it wrong and often are not even asking the right questions.
Antimalarial drugs certainly present a much greater
danger to Ebola patients than selenium tablets. That raises the question of
what other drugs in the current treatment protocol might also be dangerous to
patients since none of them have undergone clinical trials against Ebola.
Because anti-malarial drugs increase viral replication, it should be a high priority
to quickly conduct a controlled clinical trial to determine whether their
blanket use is helping or hurting EVD patients. The science suggests they are
hurting patients, leading to a greater death toll than if they were not used at
all.
Another questionable choice in the
current Ebola treatment protocol is the use of acetaminophen (Panadol, Tylanol)
as the pain killer of choice. Some doctors have laughed or cringed when I
mentioned aspirin as a potential treatment for Ebola. The representative of the
WHO in the meeting attacked me for mentioning aspirin and asked if I knew
anything about it. I did not respond that I had read over two hundred medical
journal articles on aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs)
plus two books on the subject. I am the leading expert in the world on how
aspirin and NSAIDs affects HIV disease and have designed and had clinical trials
conducted on aspirin and HIV. I have used it personally every day since 1990 as
part of the combination to treat my HIV infection.
According to a recent report in the New England
Journal of Medicine, only about one percent of those infected in the
current Ebola epidemic exhibit the symptom of hemorrhage. Then why do we refer
to this as a “hemorrhagic” fever disease? That misnomer distorts the medical
community’s understanding of the physiological processes underlying this
illness as well as its approach to treating it. EVD might more accurately be renamed
“blood clot fever” disease. Massive blood clotting, technically referred to as
disseminated intravascular coagulation (DIC), is a distinctive physiological
hallmark of this disease. However this clotting symptom is not apparent to the
physician’s eye. The hemorrhagic fever designation is oxymoronic. It
contributes to the medical community’s confusion as to how to treat EVD. One
BBC news report filmed a doctor condemning a pile of medicine boxes that
contained NSAID drugs. The doctor claimed they would be dangerous for a person
who was hemorrhaging. That is true. But EVD is not fundamentally or even
primarily a hemorrhagic disease. It is a disease that primarily exhibits blood
clotting. Paradoxically, the drugs the physician on the BBC was condemning are
the very drugs that should be helpful. This misnamed viral disease is
confusing. It certainly has confounded the budding neo-experts and most of the
doctors that are trying to treat it.
The woman representing the WHO in
group five asked, “How do we know selenium is safe for Ebola patients?” In
fact, selenium supplement tablets are 100% safe for almost any person to take.
There are no negative side effects. One person in a hundred is just slightly
allergic and one in a thousand is truly allergic. But the overall side effect
profile is low compared to almost any other drug. In general, selenium tablets are
safer than water, at least un-purified water, and certainly safer than almost
any drug. They are not only safe but also beneficial for pregnant or
breastfeeding women, and at lower doses for infants or children. Selenium
supplements are not contraindicated to - do not conflict with - any other drug.
Thus they can be used in conjunction with any other medical regimen. Not a
single death has been attributed to an overdose or misuse of selenium
supplements in over fifty years on the market. According to toxicology standards,
a fatal dose of selenium consists of approximately 3.5 grams. That is more than
1,700 full strength selenium tablets. Medical journals report that high dose
selenium therapy – about 2mg - can reduce death from sepsis by 27% while low
levels of bodily selenium increase the chance of death from sepsis by 300%. As a terminal disease condition, sepsis or
“blood poisoning” is similar in most respects to the critical phase of EVD. The
symptoms are basically the same.
Starting with the early symptomatic stages of EVD, it
is selenium depletion by the virus that causes the primary problem of DIC blood
clotting. Hemorrhaging is only rarely a very late stage manifestation. Bleeding
is caused by a combination of the hyper-oxidative damage to the blood vessels
and massive blood clotting – both caused by the sudden, dramatic loss of
selenium due to rapid viral replication. Selenium, aspirin and other NSAIDs help
prevent both of those effects – clotting and blood vessel damage.
NSAIDs have one major advantage
compared to acetaminophen. While both NSAIDs and acetaminophen reduce fever, pain
and inflammation, only NSAIDs also reduce viral replication by inhibiting
NF-kB. Doctors could use NSAIDs in combination with acetaminophen since they
work by different immunological pathways and have different side effects. In
1990 Dr Donald Kotler of Columbia University showed that asacol significantly
reduces HIV replication by approximately 65%. The drug Asacol is exactly like
aspirin except it does not prevent platelet aggregation - blood clotting. As an
NF-kB inhibitor it will also reduce Ebola virus replication rates below
untreated levels. Ibuprofen is even stronger than aspirin/asacol in all these
effects.
Oddly enough, at the Corina meeting the nutritional
committee came back with a report that advised against the “overuse” of both
pro-oxidants like iron, and antioxidants like selenium. They should have
decided one way or the other. It cannot be both. EVD is a disease of hyper -
too much - oxidation. Clearly, the pop-up experts demonstrate limited knowledge
of the underlying virological and immunological mechanisms involved in EVD and
none of these issues or medical facts were discussed during the meeting.
Obviously antioxidants that reduce viral replication and vascular damage are
preferable to pro-oxidants that do the opposite. These newly minted experts appeared
so caught up in an unrecognizably oxymoronic paradigm they no longer knew what
to recommend.
At the conclusion of the protocol
review the psychosocial committee and many others repeatedly raised the issue
of Ebola patients suffering from severe depression, hostility and confusion.
They wondered how to address this problem. No one seemed to have a solution. By
that time I just kept silent. I had said enough. Depression, hostility and
confusion are all hallmarks of low bodily selenium. According to the 2000 review
article titled “The importance of selenium to human health” by Margaret P.
Rayman in The Lancet medical journal, “low selenium status was
associated with a significantly greater incidence of depression and other
negative mood states such as anxiety, confusion and hostility.” Unsuprisingly,
this serves to highlight the fact that EVD and most of its symptoms are caused
by rapid depletion of selenium by the virus – the same process observed in late
stage Aids.
Another issue in EVD is the
involvement of the liver and kidneys. Any dietician knows one of the best sources
of selenium in the diet is liver and kidney meat. The liver and kidneys are key
organs in the immune system. Selenium is concentrated in the immune white blood
cells as well as the various organs of the immune system because selenium is
the keystone element of immunity. The reason the kidneys and liver basically
“melt away” in late stage EVD is because they are where selenium is most highly
concentrated in the body. The virus attacks them in order to gain the selenium
it needs to replicate at such a ferocious pace. The Ebola virus genetically
encodes an unusually large number of selenium molecules and because it
replicates at such an extraordinary rate it specifically attacks and ravages
high selenium content organs. One might speculate whether the virus “feeds” on
selenium supplements. To the contrary, selenium supplements reduce viral
replication, reduce oxidative stress and reduce damage to blood vessels. They
boost the immune system’s ability to fight Ebola, in part by increasing CD4
count – the white blood cells that control immune function. Selenium
supplements replace the selenium that the virus steals and the immune system
needs to work.
This
raises another question regarding the current protocol. Acetaminophen (Panadol)
can damage the liver. Liver damage is one of the most serious and frequent
negative side effects of this drug. High doses of acetaminophen cause over half
of all acute liver failures and some people are more genetically susceptible to
this reaction. It is highly questionable why acetaminophen is the drug of
choice to treat a disease that has destruction of the liver as one of its most deadly
symptoms. Thus the standard accepted EVD protocol may have gotten it grossly
wrong again. Or at the very minimum it has not been clinically proven right.
For a number of reasons ibuprofen could be preferable to acetaminophen in
treating EVD. Ibuprofen should be clinically compared to acetaminophen in a
clinical trial of Ebola patients. Doctors and health bureaucrats should stop
making unquestioning mistakes that have not been subject to clinical trials.
These protocol questions urgently need to be clinically tested so we do not
continue making these same mistakes in future epidemics. It would be quick and easy
to do so.
In the world of biology, genetics is
destiny. It makes us who we are. It determines how viruses act. Dr Ethan Will
Taylor of the University of North Carolina was the first to genetically
sequence the Ebola virus. He discovered how many selenoproteins the virus
genetically encodes and how many selenium atoms the virus requires every time
it replicates. He explained that Ebola causes “a more dramatic selenium
depletion in a matter of days than HIV infection can accomplish in ten years.”
The HIV and Ebola viruses are similar in many respects. They both attack the
immune system, cause oxidative stress, immune deficiency, and finally immune
system collapse. They both increase NF-kB to stimulate their own reproduction,
and they both deplete the body’s selenium supply. They are different in that
HIV is a lentivirus – a “slow” virus – and Ebola a filovirus, the most lethal
of more than a dozen known hemorrhagic fever viruses. Ebola-Zaire is a very
“fast” virus indeed. It kills within two to three weeks of infection. Like most
viruses, both HIV and Ebola-Zaire genetically encode selenium, but because
Ebola encodes so much selenium and replicates so rapidly, it drains selenium
from the body three hundred times faster than HIV. Depleting the body’s store
of selenium is at the core of both how HIV causes Aids and how Ebola causes
death from EVD.
At the Corina Hotel meeting I asked
the co-chair representing the NIH about the need to test the approximately
twenty-five existing approved anti-viral drugs against Ebola. He claimed the
NIH had already conducted in vitro
test tube trials on all those drugs and none of them showed antiviral activity
against Ebola-Zaire. Somehow I did not completely believe him because if that
is true, they must not have tested selenium, NSAID drugs or lamivudine. A month
after I spoke to the NIH co-chair of the Corina protocol meeting the Journal
of Emerging Microbes and Infections reported that researchers had found
fifty-three different existing drugs that show some activity against Ebola in
the test tube. Had the NIH somehow missed all of those? Thirty years ago Nancy
Reagan made a similar statement when she told the American public that they
were “testing everything they can” against HIV. Again “everything” apparently did
not include selenium, aspirin, asacol or other NSAIDS. At least they failed to
inform people with HIV of the benefits if they did. So two dozen antiviral
drugs that just might work, or should at least be tested, remain on the shelf
untested against Ebola. The treatment protocol review meeting at the Corina
Hotel was designed to make sure they will be blocked from testing or at the
very minimum significantly delay their testing. Testing them would be cheap, safe
and quick – a matter of weeks. But the Corina meeting put an end to that. Using
any of them, on an informal trial basis, supposedly was banned by this meeting.
That begs the question about the antiviral drug used to treat HIV, lamivudine
(3Tc).
In September 2014 Liberian Dr
Gabriel Logan who oversees an ETU at Tubmanburg Hospital treated fifteen Ebola
patients with the first generation, not terribly effective HIV antiretroviral
drug (ARV) lamivudine. Only two of his patients died – an 86.7% survival rate.
Following the Corina protocol meeting I met with the chief medical officer of
Liberia, Dr Bernice Dahn and inquired about this. I expressed my suspicion that
perhaps all these patients had not been confirmed Ebola patients. She made a quick
cell-phone call and confirmed they had been positive for Ebola. If this is true,
it would be remarkable and would tend to contradict the assertion by the NIH
co-chair of the Corina meeting who claimed that all these ARVs and other
antiviral drugs had been tested in vitro against
the virus and found wanting. It is curious that after the success with
lamivudine was reported on the BBC, someone from the WHO in Geneva, Switzerland
phoned the Liberian regulatory authority and demanded to know where Dr Logan
had gotten lamivudine. After all, lamivudine is one of the oldest, most common
ARV drugs, found in almost every government clinic in Sub-Saharan Africa. In
advanced HIV therapeutics it has been replaced by a fourth generation
three-drug combination ARV that includes lamivudine called Truvada. If
lamivudine works against Ebola, then Truvada should work extraordinarily well.
But this is exactly what the Corina meeting was designed to put an end to - testing
all these currently approved anti-viral drugs that might conflict with the
interests of the international pharmaceutical industry that wants to test their
own new, hopefully more specific experimental drugs. To paraphrase George
Orwell’s Animal Farm, the pharmaceutical corporate paradigm is “Old [cheap]
drugs bad. New [expensive] drugs good.”
So why would anyone oppose the use
of selenium or lamivudine to treat Ebola, the only two treatments that had
shown significant ability to reduce the death toll among those infected? According
to the Economist magazine dated 1 November 2014, US and European
governments and pharmaceutical companies have spent five hundred million
dollars trying to develop drugs to treat Ebola. That was before the 2014 Ebola
crisis started. So far they have tested Z-Matt on six patients, three lived,
three died. Other anti-Ebola drugs have been rushed forward for trial but we do
not know if they will be effective, or if so, how effective. No one knows how
safe they are. Do US health agencies and the WHO oppose the use of selenium and
NSAIDs to protect that half billion dollar investment? There does not seem to
be any solid scientific basis to oppose the use of selenium or lamivudine – and
significant scientific rationale to support them. So does the current treatment
strategy that ignores the use of selenium actually hurt those infected with
Ebola. At the very minimum it lowers the survival rate from a minimum of 68%
achieved by administering 1.2 mg selenium daily, down to the basic 45% achieved
with supportive care alone. That difference adds up to hundreds of lives lost
and families destroyed. Does the current truncated EVD treatment protocol
endanger the world by increasing the chance this disease may spread? It might.
There is a huge conflict of interest
here. The health agencies of the US government and the World Health
Organization have clearly come down on the side of protecting the commercial
interests of the pharmaceutical industry as opposed to saving the lives of
people infected with Ebola. People with Ebola will continue to die in
unnecessary numbers while the pharmaceutical industry awaits its chance to use
them as guinea pigs to test their new drugs. This is a harsh indictment. But
when you boil it down to the core residue of the hidden agenda of the protocol review
meeting, this seems to be what is left
Of course we can eventually turn
back the tide of this epidemic without ever having to adequately treat the
patients who are dying. The same American, European and international organizations
I berate here are doing an outstanding job in some places getting a hold on this
epidemic. In Liberia they are turning the tide and bringing down the numbers
through a combination of education, diligent epidemiological contact tracing,
and insuring safe burial practices. But how can we turn our backs on the
individuals and families who are suffering most, those who are infected and
dying. This is especially true of the local West African doctors and nurses on
the front line who have been hit the hardest. The establishment medical
superpowers turn their backs on them by ignoring and restricting scientific
enquiry and trying to shove quick, simple, cheap clinical trials of existing
antiviral drugs into the closet, locking the door and turning off the light.
That was the agenda of the Corina Hotel protocol review meeting. That hidden
agenda succeeded spectacularly, when from a humanitarian point of view it was a
colossal failure.
The health-interested public
deserves an open debate about Ebola research and treatment issues. Those concerns
were shoved under the rug in a well-worn, two star hotel in a far off African
country with the expectation no one would notice. The editorial in the 18
October Economist magazine cover titled “The War on Ebola” suggested
that, “different treatments need to be tested against each other in a
systematic way to see which ones work and which will not.” Existing, approved,
safe and effective antiviral drugs offer the quickest hope for finding an
effective combination therapy to treat Ebola disease. Who will fund this
research? It would cost less than one million dollars and take two months to
complete testing half a dozen existing, safe antiviral drugs. Who will step up
to the plate to do this? Where is a true hero with the financing when the world
needs one? A fortune in government money is being thrown at the Ebola epidemic.
Some of it, as at the Corina meeting, is used to cover-up and prevent effective
therapies from getting to those who need it most. The rational, logical
approach to testing potential EVD therapies proposed by the Economist is
exactly what the NIH, FDA and the WHO are trying to put a clamp on. Of course
testing has to be regulated. But it also needs to be advanced on a logical,
scientific basis as fast as humanly possible, and not just as a sop to the
pharmaceutical industry. It does not cost much or take long to test drugs
against Ebola. Within two to three weeks you know if a medication works or not.
It either improves the survival rate or it does not. Nothing else matters to
the patient or their family. To shut down testing as the Corina protocol meeting
proposed, instead of expediting it, could even be considered criminal. It could
contribute to rather than retard the potential spread of Ebola. It also
contributes to the death of the doctors, nurses and other healthcare workers
who have fought and died bravely battling this epidemic. Holding back research
to swiftly find an improved combination of effective therapies contributes to
the collapse of the health care systems in the three nations most affected as
more and more heath care workers die.
So the world medical community can
follow the liberal, enlightened, nonpartisan advice of the Economist
editorial staff. Or it can follow the uber-conservative, corporatist,
close-minded, anti-investigative agenda of the US health agencies and the WHO
and shut down quick, simple, inexpensive trials. With minimal funding clinical
trials could be run by the Ministries of Health of the three affected countries
using local doctors - if they were free to do so. It is a clear cut choice. We
can save lives and cut this epidemic down to size as rapidly as possible. Or we
can continue hoping pharmaceutical companies will come up with something,
sooner or later, that might be more or less effective than what is already sitting
on the shelf. How long the new drug development process takes to discover drugs
more effective than selenium and lamivudine’s much improved successor Truvada, or
the combination of the two is anyone’s guess.
The governments of the region need
to decide which path to follow – testing as much and as soon as possible or
waiting passively for those with superior resources to follow the almost
assuredly longer path of new drug research. At an indeterminate future time
these companies will present the world with their maybe slightly more superior
but much more expensive way to treat Ebola disease. Frankly it would be best to
take both the high road and the low road. But do not let anyone blockade the
low-tech, quick, simple, easy road just because they prefer the highly
technical, lengthy, more difficult high road of experimental investigative new
drug development. Given the billions of dollars headed to this poor region that
will “sway” the decision, unfortunately hope for a rational humanistic approach
to research is fading.
When accused of being lucky in his discoveries, Louis
Pasteur retorted, “Chance favours the prepared mind.” I prepared for this Ebola
epidemic through thirty years of experience with and research on HIV disease. Today
we need to cut the Gordian knot that Ebola presents. Governments should move
rapidly forward to test and discover effective treatments for EVD without delay.
They should not place impediments in the way of research other than reasonable regulations
designed to expedite rather than shut down the search for a functional cure for
this disease. I believe we can turn the untreated survival rate of 10% on its
head. Within three months we might achieve a survival rate close to 90% if we
add selenium and Truvada to basic supportive care. That will be impossible if
West Africa is chained by bureaucratic red tape and led only up the high road
of new drug development for the sole purpose of increasing pharmaceutical
company profits. That would be neither the medically ethical nor the moral,
humanitarian way out of this international health crisis. For even after we put
out the fire of the 2014 Ebola epidemic, another Ebola, SARS, MERS or deadly avian
influenza epidemic surely awaits around the corner. We should learn the lessons
of this epidemic while we can. The 1918 influenza epidemic killed fifty million
people worldwide. Next time Ebola, SARS, MERS or influenza could be much worse.
No one should ever again say, “There is no treatment
for Ebola.” There is.
