Tak<strong>in</strong>g Ivermect<strong>in</strong> won’t<br />
s<strong>top</strong> COVID-19 <strong>in</strong>fection<br />
— Experts<br />
By Sola Ogundipe<br />
<strong>in</strong>ce news broke that Ivermect<strong>in</strong> has a<br />
Sperceived therapeutic effect aga<strong>in</strong>st the<br />
COVID-19 virus, there has been mad rush for<br />
the drug all <strong>over</strong> the world.<br />
With countless tablets of the drug be<strong>in</strong>g sold<br />
<strong>over</strong>-the-counter, the risk of misuse, <strong>over</strong>dose,<br />
and purchase of the animal version is<br />
dangerously high.<br />
In Nigeria particularly, the shelf price of<br />
Ivermect<strong>in</strong> tablets has gone up appreciably <strong>in</strong><br />
recent times as desperate stockpil<strong>in</strong>g of large<br />
quantities commenced <strong>in</strong> the wake of the<br />
emergence of the Delta variant among other<br />
concerns.<br />
But health experts have warned that<br />
Ivermect<strong>in</strong> has no effect <strong>in</strong> curtail<strong>in</strong>g COVID-<br />
19 and called for cautionary use.<br />
As the contr<strong>over</strong>sy rages around the drug, an<br />
<strong>in</strong>ternational group of experts has faulted the<br />
series of studies claim<strong>in</strong>g that the drug is a<br />
miracle remedy aga<strong>in</strong>st the disease.<br />
The scientists said the studies claim<strong>in</strong>g that<br />
Ivermect<strong>in</strong> can treat the coronavirus<br />
disease have been found to be not only deeply<br />
flawed, but unreliable even as they call for an<br />
<strong>over</strong>haul of medical research to prevent more<br />
mis<strong>in</strong>formation around unverified cures.<br />
Flawed studies mak<strong>in</strong>g<br />
the rounds<br />
In a letter <strong>in</strong> the Nature Medic<strong>in</strong>e, a scientific<br />
journal, the group of researchers expla<strong>in</strong>ed<br />
how ris<strong>in</strong>g doubts about studies claim<strong>in</strong>g<br />
ivermect<strong>in</strong> could help treat Covid are flawed.<br />
They detail how one such piece had concern<strong>in</strong>g<br />
discrepancies <strong>in</strong> its data, which led to its<br />
eventual withdrawal.<br />
Accord<strong>in</strong>g to the World Health<br />
Organisation, WHO, and the US Food and<br />
Drug Adm<strong>in</strong>istration, FDA, ivermect<strong>in</strong> is not<br />
authorized or approved for use <strong>in</strong> prevent<strong>in</strong>g<br />
or treat<strong>in</strong>g COVID-19 <strong>in</strong> humans. The CDC<br />
notes that Ivermect<strong>in</strong> is approved for human<br />
use to treat <strong>in</strong>fections caused by some parasitic<br />
worms and head lice and sk<strong>in</strong> conditions like<br />
rosacea.<br />
The scientists argue that currently available<br />
data do not show ivermect<strong>in</strong> is effective aga<strong>in</strong>st<br />
COVID-19, although cl<strong>in</strong>ical trials assess<strong>in</strong>g<br />
ivermect<strong>in</strong> tablets for the prevention or<br />
treatment of COVID-19 <strong>in</strong> people are ongo<strong>in</strong>g.<br />
Warn<strong>in</strong>g that tak<strong>in</strong>g large doses of<br />
ivermect<strong>in</strong> is dangerous, the experts say<br />
ivermect<strong>in</strong> should be procured through<br />
legitimate sources such as a pharmacy, and<br />
taken exactly as prescribed.<br />
•Drug not authorised for coronavirus<br />
treatment or prevention<br />
Part of the anxiety is that Ivermect<strong>in</strong> products<br />
are different from those approved for humans<br />
and that the use of animal ivermect<strong>in</strong> for the<br />
prevention or treatment of COVID-19 <strong>in</strong><br />
humans is dangerous.<br />
In another research, they said elements <strong>in</strong> its<br />
methodology were flawed, and the errors were<br />
then compounded by larger reviews, called<br />
meta-analyses, which based their f<strong>in</strong>d<strong>in</strong>gs <strong>in</strong><br />
large part on these flawed studies.<br />
Impossible numbers,<br />
unexpla<strong>in</strong>able mismatches <strong>in</strong> data<br />
The scientists add that this<br />
study is not alone and predict<br />
others claim<strong>in</strong>g ivermect<strong>in</strong><br />
has a cl<strong>in</strong>ical benefit will also<br />
be withdrawn <strong>in</strong> the com<strong>in</strong>g<br />
months due to their<br />
“impossible numbers”, and<br />
“unexpla<strong>in</strong>able<br />
mismatches” <strong>in</strong> the data.<br />
But the damage may have<br />
been done with many<br />
hundreds of thousands of<br />
patients that have taken the<br />
drug, accord<strong>in</strong>g to the<br />
pr<strong>in</strong>cipal signatory of the<br />
letter, Kyle Sheldrick of the<br />
University of New South<br />
Wales <strong>in</strong> Australia.<br />
“This research has created<br />
undue confidence <strong>in</strong> the use<br />
of ivermect<strong>in</strong> as a<br />
prophylactic or treatment for<br />
Covid, has usurped other<br />
research agendas, and<br />
Even the levels<br />
of ivermect<strong>in</strong><br />
for approved<br />
human uses<br />
can <strong>in</strong>teract<br />
with other<br />
medications,<br />
like bloodth<strong>in</strong>ners<br />
probably resulted <strong>in</strong> <strong>in</strong>appropriate treatment<br />
or substandard care of patients,” they wrote.<br />
As a result, the scientists called for an<br />
<strong>over</strong>haul of how cl<strong>in</strong>ical data on Covid is<br />
analysed. They said creators of meta-analyses<br />
should both request and review the <strong>in</strong>dividual<br />
patient data, the raw from <strong>in</strong>dividual<br />
participants <strong>in</strong> a study or trial, of the studies<br />
they use to reach their wider conclusions.<br />
Similarly, the scientists said cl<strong>in</strong>ical trials<br />
on Covid treatment should also make this data<br />
available to ensure this k<strong>in</strong>d of analysis could<br />
happen. Any study that refuses to do so should<br />
be treated with extreme caution or omitted<br />
from analysis entirely, the scientists said.<br />
They acknowledge their call may be<br />
contr<strong>over</strong>sial because it represents a change<br />
to a “long-accepted” scientific practice but<br />
added that the ivermect<strong>in</strong> example justifies it.<br />
“We believe that what has happened <strong>in</strong> the<br />
case of ivermect<strong>in</strong> justifies our proposal: a<br />
poorly scrut<strong>in</strong>ized evidence base supported the<br />
adm<strong>in</strong>istration of millions of doses of a<br />
potentially <strong>in</strong>effective drug globally. Yet when<br />
this evidence was subjected to a very basic<br />
numerical scrut<strong>in</strong>y it collapsed <strong>in</strong> a matter of<br />
weeks,” they wrote.<br />
Ivermect<strong>in</strong> <strong>in</strong>effective<br />
aga<strong>in</strong>st viruses<br />
Meanwhile, Dr. Timothy Geary, one of the<br />
world’s foremost experts of Ivermect<strong>in</strong>, also<br />
warned that Ivermect<strong>in</strong> is <strong>in</strong>effective aga<strong>in</strong>st<br />
COVID-19 or <strong>in</strong> fight<strong>in</strong>g viruses generally.<br />
Geary, the Research Chair <strong>in</strong> Parasite<br />
Biotechnology at McGill<br />
University <strong>in</strong> Montreal, Canada,<br />
says that the 2020 study which<br />
spawned much of the Ivermect<strong>in</strong>craze<br />
is not be<strong>in</strong>g correctly read.<br />
In an <strong>in</strong>terview, he expla<strong>in</strong>ed<br />
that although the study did show<br />
that Ivermect<strong>in</strong> could <strong>in</strong>hibit the<br />
replication of COVID-19 virus<br />
cells, many people are<br />
mis<strong>in</strong>terpret<strong>in</strong>g the study and<br />
believ<strong>in</strong>g that the drug has viruskill<strong>in</strong>g<br />
properties.<br />
Geary expla<strong>in</strong>ed, though, that<br />
the concentration of Ivermect<strong>in</strong><br />
used <strong>in</strong> the study was so high that<br />
it could not be used for treatment<br />
<strong>in</strong> a human, and would likely<br />
cause an <strong>over</strong>dose.<br />
“In that study they showed that<br />
<strong>in</strong> cell cultures, Ivermect<strong>in</strong> could<br />
<strong>in</strong>hibit (Covid) replication, but<br />
the concentrations required for<br />
that effect were <strong>in</strong> a range called<br />
the micromolar range - very high<br />
concentrations relative to what you would f<strong>in</strong>d<br />
<strong>in</strong> the plasma of a treated person or an animal,<br />
which would be 20 to 50 times lower.”<br />
Prescribed versions of Ivermect<strong>in</strong> drug come<br />
<strong>in</strong> pill form, so liquid versions are not advised<br />
and can lead to <strong>over</strong>dose which can cause<br />
serious side effects and even death. They<br />
warned aga<strong>in</strong>st the mis<strong>in</strong>formation be<strong>in</strong>g<br />
spread around that it’s okay to take large doses<br />
of ivermect<strong>in</strong>. It is not okay, they stated.<br />
“Even the levels of ivermect<strong>in</strong> for approved<br />
human uses can <strong>in</strong>teract with other<br />
medications, like blood-th<strong>in</strong>ners. You can also<br />
<strong>over</strong>dose on ivermect<strong>in</strong>, which can cause<br />
nausea, vomit<strong>in</strong>g, diarrhea, hypotension (low<br />
blood pressure), allergic reactions (itch<strong>in</strong>g and<br />
hives), dizz<strong>in</strong>ess, ataxia (problems with<br />
balance), seizures, coma and even death.”<br />
The experts note that currently, the most<br />
effective ways to limit spread of COVID-19<br />
<strong>in</strong>clude gett<strong>in</strong>g a COVID-19 vacc<strong>in</strong>e and<br />
follow<strong>in</strong>g safety precautions and guidel<strong>in</strong>es.<br />
To improve<br />
cancer survival,<br />
scientists<br />
<strong>in</strong>vestigate what<br />
kills patients<br />
cientists don’t really know what kills<br />
Smany cancer patients, but fruit fly<br />
research could provide answers accord<strong>in</strong>g<br />
to University of California, Berkeley,<br />
researchers who are f<strong>in</strong>d<strong>in</strong>g<br />
commonalities between the two that could<br />
lead to ways to prolong the lives of cancer<br />
patients.<br />
Fruit fly research is already po<strong>in</strong>t<strong>in</strong>g to<br />
a new anti-cancer strategy dist<strong>in</strong>ct from<br />
the conventional goal of destroy<strong>in</strong>g the<br />
tumor or cancerous cells. Instead, the<br />
research suggests, launch<strong>in</strong>g an attack<br />
aga<strong>in</strong>st the destructive chemicals the<br />
cancer is throw<strong>in</strong>g off could <strong>in</strong>crease<br />
survival rates and improve patients’<br />
health.<br />
“It’s a really complementary way of<br />
th<strong>in</strong>k<strong>in</strong>g about therapy,” said David<br />
Bilder, UC Berkeley professor of<br />
molecular and cell biology. “You’re try<strong>in</strong>g<br />
to help the host deal with the effects of the<br />
tumor, rather than kill<strong>in</strong>g the tumour<br />
itself.”<br />
Jung Kim, a postdoctoral fellow <strong>in</strong><br />
Bilder’s lab, recently disc<strong>over</strong>ed that<br />
tumours <strong>in</strong> fruit flies release a chemical<br />
that compromises the barrier between the<br />
bloodstream and the bra<strong>in</strong>, lett<strong>in</strong>g the two<br />
environments mix — a recipe for disaster<br />
<strong>in</strong> numerous diseases, <strong>in</strong>clud<strong>in</strong>g <strong>in</strong>fection,<br />
trauma and even obesity. In collaboration<br />
with the labs of UC Berkeley professors<br />
David Raulet and Kaoru Saijo, Kim and<br />
Bilder subsequently demonstrated that<br />
tumors <strong>in</strong> mice that release the same<br />
chemical, a cytok<strong>in</strong>e called <strong>in</strong>terleuk<strong>in</strong>-6<br />
(IL-6), also make the blood-bra<strong>in</strong> barrier<br />
leaky.<br />
More importantly, they were able to<br />
extend the lifespan of both fruit flies and<br />
mice with malignant tumors by block<strong>in</strong>g<br />
the effect of the cytok<strong>in</strong>e on the barrier.<br />
“The IL-6 cytok<strong>in</strong>e is known to cause<br />
<strong>in</strong>flammation. What’s new here is that this<br />
tumor-<strong>in</strong>duced <strong>in</strong>flammation is actually<br />
caus<strong>in</strong>g the blood-bra<strong>in</strong> barrier to open.<br />
If we <strong>in</strong>terfere with that open<strong>in</strong>g process<br />
but leave the tumor alone, then the host<br />
can live significantly longer and healthier<br />
with the same tumor burden,” Bilder said.<br />
IL-6 plays other important roles <strong>in</strong> the<br />
body, so to benefit cancer patients,<br />
scientists would have to f<strong>in</strong>d a drug that<br />
blocks its action at the blood-bra<strong>in</strong> barrier<br />
without alter<strong>in</strong>g its effects elsewhere. But<br />
such a drug could potentially extend the<br />
life span and health span of human cancer<br />
patients, he said.<br />
Accord<strong>in</strong>g to Bilder, scientists still are<br />
uncerta<strong>in</strong> what causes death <strong>in</strong> many<br />
cancer patients. Cancer of the liver, for<br />
example, clearly destroys the function of<br />
an organ essential for life. However, other<br />
organs, like the sk<strong>in</strong> or the ovaries, are<br />
less critical, yet people die from cancer <strong>in</strong><br />
these sites, too, sometimes very quickly.<br />
And though cancers often metastasize to<br />
other organs — multiple organ failure is<br />
one of the ma<strong>in</strong> causes of cancer death<br />
listed by doctors — Bilder questions if<br />
that’s the whole story.<br />
“Many human cancers are metastatic,<br />
but that doesn’t change the basic<br />
question: Why does the cancer kill?” he<br />
said. “If your tumor metastasized to the<br />
lung, are you dy<strong>in</strong>g because of lung failure<br />
or are you dy<strong>in</strong>g from someth<strong>in</strong>g else?”<br />
For that reason, he works with nonmetastatic<br />
tumors implanted <strong>in</strong> fruit flies<br />
and mice and looks for systemic effects,<br />
not merely the effects on the tumorconta<strong>in</strong><strong>in</strong>g<br />
organ itself.<br />
One systemic effect of cancer is<br />
cachexia, the <strong>in</strong>ability to ma<strong>in</strong>ta<strong>in</strong> weight,<br />
which leads to wast<strong>in</strong>g of muscle even<br />
when the patient is receiv<strong>in</strong>g <strong>in</strong>travenous<br />
nutrition. While Bilder disc<strong>over</strong>ed one<br />
possible reason for this — cancers release<br />
a chemical that prevents <strong>in</strong>sul<strong>in</strong> from<br />
stor<strong>in</strong>g energy <strong>in</strong> the body — other<br />
scientists have found additional<br />
substances released by cancers that may<br />
also be responsible for tissue wast<strong>in</strong>g.
