Exciting Developments with Dr. David Brady
Today we speak with Dr. David Brady on what was supposed to be emerging testing in GI, but instead we spent the entire time discussing SARS-CoV-2, and some exciting developments with the lab he works with, DSL or Diagnostic Solutions Laboratory and how they are working on antibody testing as well as testing to identify cases. We discuss how and when integrative providers can step in and try to assist in this effort which is currently being handled through our major hospital systems. This conversation was insightful and very interesting. In addition to that, Dr. Brady really has been looking deep into the mechanisms through which SARS-CoV-2 infects and makes people ill. Namely through the acute respiratory distress syndrome that it causes, and the cytokine storm or the inflammatory cascade that underlies that may be initiated by this and Inflammasome NLPR3.
There are actually some natural agents that have been shown to suppress this Inflammasome, including melatonin, which was completely new to me. Also vitamin C and quercetin have been shown to be able to inhibit this specific Inflammasome. Now we don’t have the luxury of having the data that I always harp on having, which would be a clinical trial. There has not been nearly enough time, although there is some research being actively performed, and these anecdotes are being used to make the best inference that we can. So this would be an example of being evidence based, but not evidence limited of course. So this episode is all about SARS and COVID-19, testing and treatment options in this rapidly evolving landscape with Dr. David Brady. I hope you’ll tune in and get some updates on this obviously very prevalent topic for which we are all trying to do the best job that we can.

Testing and Natural Antiviral Strategies
A big question on everyone’s mind right now is whether or
not we have been exposed to SARS-COV2, the novel coronavirus, and whether we
can get a test if we need one. Most of us are also wondering how to avoid
getting sick, or how to support our body in case we do get sick. Dr. David
Doctor, Functional Medicine Doctor, and Chief Medical Officer of Diagnostic
Solutions Laboratory says there’s good news about both.
Coronavirus Antibody Testing and Stool Testing
Diagnostic Solutions Laboratory is well-known for their
popular GI-MAP stool test, which helps practitioners and patients understand
what’s happening in their gut. But DSL has put its technology to work testing
infection, the virus that causes the COVID-19 illness.
Currently, access to coronavirus testing is limited and test turnaround time from public health laboratories and private labs is slow. Dr. Brady says other quick-turnaround tests, like finger-prick tests and self-administered nasal swabs haven’t shown good accuracy. Better testing methods are going to be very important moving forward.
As we continue to work to flatten the curve, health officials agree that widespread, accurate antibody testing is going to be important to determine who can go to work or school versus who should continue to practice social distancing.
Dr. Brady says DSL is working on quantitative and qualitative serum (blood) antibody testing to help with this effort. Serum coronavirus antibody test kits will be available to healthcare providers from DSL. Because it’s been shown that the virus can be present in stool up to six weeks after a person is asymptomatic, DSL is now also offering stool testing for coronavirus diagnosis as well.
Dr. Brady agreed that
antibody testing or stool testing is probably the best way for integrative
health care practitioners to support their patients during the coronavirus
How Coronavirus Overwhelms the Body
All viruses have special proteins called “viroporins”. These
viroporins are the proteins that enable viruses to enter their host’s cell
membranes, so they can begin replicating. According to Dr. Brady, this coronavirus
has two novel viroporins, called ORF-3A and E Protein, that activate an
inflammasome called NLRP-3. Brady says that NLRP-3 is the initial domino that
can lead to a cytokine storm.
“NLRP-3 is the key inducer of large amounts of inflammatory cytokines, mainly IL-1beta, IL-10, and others. And the production of IL-1beta in particular is very tightly controlled and dependent upon NLRP-3.”
It’s unclear why this happens to some people and not others, but Dr. Brady says there is some preliminary data to suggest certain genetic SNPs may be partly responsible.
DrMR: Hi everyone. I am very excited to announce we have two new versions of our Elemental Heal available. Elemental Heal in case you haven’t heard of it, is our great-tasting meal replacement, hypoallergenic gut-healing formula. We now have two new versions: One is low carb and the other is a fully elemental whey free and dairy free formula, and they both taste great. The really nice thing about these is they are the only of their kind available on the market. Including the fact that they don’t require a doctor’s note in order to use them.
So whether using Elemental Heal as a morning shake meal replacement, or as a mini gut reset for one, two, three or four days, or even all the way through to the application of exclusive or semi-exclusively for two to three weeks, we now have a formula that should fit your needs no matter how you’re using it.
If you go to drruscio.com and into the store, we’re offering 15% off any one of our Elemental Heal formulas. This discount is limited to one per customer and if you use the code, “TryElementalHeal” at checkout, you’ll get that 15% off. Please give them a try and let me know what you think. I believe you will find them to be not only a great tasting but also really friendly on the gut and will help give you a bump and a boost in how you’re feeling.
Coronavirus Antiviral Natural Therapeutics
While there have not been any direct research studies, there
is anecdotal evidence that some natural therapeutics and herbal
medicines can support the immune system and reduce the severity and duration
Some sources have recommended against using immune
stimulators such as elderberry, medicinal mushrooms, or vitamin D. Dr. Brady
disagrees with this recommendation, saying:
“…if you’re really progressing with your respiratory situation in a negative way…I probably would not use any of these immune upregulators. But the vast majority of us, if we confront this virus…want a good, robust immune response. If you can reduce the progression of the infection to the point [of] tipping over this edge into the cytokine storm, it would seem that these preventative agents would actually be more helpful.”
Here’s a summary of the antiviral natural therapeutics we
According to Dr. Brady, melatonin tightly suppresses the
NLRP-3 inflammasome. He suggests that this may be a reason why younger people
seem to be more resilient to the virus than older people. Melatonin production
tapers off as we age.
He says that in animal models of sepsis, using melatonin has
shown promise as a down-regulator of the cytokine storm.
According to Dr. Brady, vitamin C downregulates NLRP-3. He says,
C acts on a multitude of levels, reducing oxidative stress, regulating
hypoxia signaling, helping mitochondrial membrane potential…all these things
preclude a cytokine storm.” He says this is why we’re seeing hospitals use IV vitamin C.
Quercetin, Vitamin C,
Quercetin is a plant polyphenol that has a special affinity
for the lungs. Dr. Brady says that quercetin, when given with vitamin C as
well as vitamin E in the form of tocotrienols, is a powerful and effective antiviral
Artemisinin generally has a similar action to the
antimalarial drugs hydroxychloroquine and Palenquil, which are
sometimes used to treat rheumatoid arthritis, systemic lupus erythematosus
(SLE), and other autoimmune diseases. These drugs are anti-inflammatory in
these conditions, though with an unknown mechanism. They are currently being
used in clinical
trials against coronavirus infection. Dr. Brady says it’s unclear
how the antimalarial drugs or artemisinin work for coronavirus, but they have
Dr. Brady also says that many plant polyphenols are antiviral,
by preventing viruses from entering our cell membranes. These include:
- EGCG from
green tea (he says to use with caution, as this can elevate liver enzymes)
- Allicin from
from cayenne pepper
Geraniol (GG, which is an antiviral agent used in Japan)
Zinc & Copper
Dr. Brady says zinc with a small amount of copper offers
mucosal protection by preventing viruses from docking and entering cells in the
Some research has shown that probiotics reduce the severity
of and duration of influenza and upper respiratory infections. And while these
data don’t deal specifically with coronavirus, we can infer probiotics may provide
some amount of protection against the effects of SARS-CoV-2.
The Bottom Line
Coronavirus antibody testing and stool testing from
DSL is set to help us understand our coronavirus status. Integrative medicine
practitioners can best support their patients by helping them access this
testing, as long as they are not drastically ill. And a wide range of natural
or herbal therapeutics can help support the immune system before,
during, and after coronavirus infection.
