Coming up on this episode of The Doctor's Pharmacy.
The single best thing that you can do for your life is have a healthy diet and do a
reasonable amount of exercise.
The biggest single killer of humans is cardiovascular disease, statistically.
80% of premature death due to cardiovascular disease is preventable by a healthy diet and
exercise and not smoking.
If you're a healthcare practitioner like I am,
you know how hard it is to keep your medical knowledge up to date, especially when it comes
to functional and specialty lab testing. You could spend a ton of time waiting through the
latest medical literature, but that can be hard to fit into an already busy schedule.
A better answer is Rupa University. Rather than spending countless hours combing through reports,
Rupa University hosts both six-week deep dive boot camps and free training sessions every week,
led by experts in the industry who provide an up-to-date overview of a lab, topic, or health
concern. Rupa University is the number one educational institute for root cause medicine,
with over 20,000 practitioners a year learning about functional and specialty lab testing. If
you want to level up your knowledge of functional lab tests, make sure to visit rupainiversity.com.

Hi, I'm Dr. Mark Hyman, a practicing physician
and proponent of systems medicine, a framework to help you understand the why or the root cause
of your symptoms. Welcome to The Doctor's Pharmacy. Every week, I bring on interesting
guests to discuss the latest topics in the field of functional medicine and do a deep dive on how
these topics pertain to your health. In today's episode, I have some interesting discussions with
other experts in the field. So let's just trump right in. Well, Dr. Nicholson, welcome to the Doctors
Pharmacy Podcast. I'm so happy to have you. You've come all the way from Australia, down under. You're
here at the annual International Conference for Functional Medicine. I'm so privileged to be able
to talk to you because you're one of the pioneers in a new field of medicine that is just going to
be what everybody's doing in a few years.
And you've been the pioneer in this field, what we call phenomic medicine.
Now, we're going to define what that is in a minute.
But we're talking here about a new era, a new revolution in science and the science of medicine and the application of that science to treat complex chronic illness
that doesn't lend itself well to a single biomarker treated with a single drug to create
a single outcome, like high blood pressure, blood pressure pill, lower blood pressure.
Biology is way more complicated than that. And in medicine, we kind of do what we do,
but it's not really looking very deeply into the human body.
And up until the last few years, we really haven't been able to understand what's going on.
We do a blood chemistry panel of 20 or 30 analytes.
We might do a cursory physical exam.
You might get a few x-rays or imaging here and there.
But it's kind of the dark ages when it comes to really what now is available to us to understand the complexity of the human biology and to understand this world of the omic medicine, which is our genes,
how they are expressed into what we call the phenome, which is the body's expression of
all the influences that have washed over us through our lifetimes. And we're going to
have you define it as well. And we're entering an era where we're moving away from a one-size-fits-all
medicine to a highly personalized form of medicine that's based on your particular genes, biology,
experiences, exposures. And that's going to help us to identify patterns in your story, in your data,
and a lot more data than we're capturing now, which we're going to be able to capture more over time, to be able to create a predictive model of where you're headed
on the continuum from wellness to illness. And so your work has really done a lot of the sort of
hard, sort of challenging work of making sense of an enormously complex array
of scientific advances that have happened so fast
that we can't even imagine how profound it is.
And it's kind of akin, in my view,
to sort of the discovery of the microscope
or the discovery of like the electron microscope
to be able to see, or the telescope,
to see what's happening in a world
that we never saw before.
So can you kind of, before we get into sort of the omics and whatever,
can you kind of talk about what is precision medicine, personalized medicine,
and how does it differ from what doctors are doing now in conventional medicine,
but I was taught in medical school?
Well, thanks for that interesting introduction.
I've covered a lot already.
You've learned a lot. I was supposed to be learning from you.
So precision medicine comes under a number of different titles, terms, as stratified
medicine, precision medicine, personalized medicine, and all of those things, the different
flavors of the same thing, but they're all about getting the right treatment for the right person based on some knowledge about their biology, some fairly deep knowledge about their biology.
And to a lot of people these days, talking about scientists and doctors now, they think of precision or personalized medicine as being very genomically orientated.
So your genes will tell you what is going on in your body and
what sort of things you should look out for. But I think it was Francis Crick first described
the genome as the blueprint for life. And that's an interesting and revealing terminology
basically coined in the 1950s. The blueprint for life. The blueprint is a set of plans for building something.
So if you have a blueprint for a nuclear submarine, you can build that.
But it won't tell you about nuclear power, about the fact that you're splitting atoms
or anything like that, or even what electricity is. It doesn't tell you how
the thing works. And your genes, of course, give
you as an organism flexibility for living in a
complex changing environment. The world changes all the time. And you have to have enough genomic,
genetic flexibility to be able to accommodate to the changes that exist. And when evolution occurs,
it's your adaptability of your genes to go into new environments to capture new food sources. yw'r adeithiad o'ch genedlaethau i fynd i mewn i amgylchiadau newydd i gynnal
fwy o fwyderau bwyd. Felly mae yna gwybodaeth ymdrinol yn y genoedd sydd ganddo rhai
gwybodaethau, mae'n rhoi adeithiad i chi, ond mae hefyd yn gallu eich gallu mynd i mewn i amgylchiadau newydd.
Y peth sy'n newid yn wir yw'r fath o beth y gallwch chi fynd i mewn i amgylchiadau newydd, yw'r
microbes sy'n byw yn eich amgylchiad. Mae'r microbes yn gyfadd rhwng chi a'r amgylchiad. Felly, Actually the microbes that live in you the microbes are an interface between you and the environment
So all environmental influences dietary sources pollutants
Whatever it is come through a microbial layer on your surfaces skin your lungs in the course your gut and that
modulates what happens in your body, so
For a start the genomic hypothesis that you know have able to predict medical outcomes based just on human genomes is incomplete because it doesn't include all the microbial genomes
which are individual to all of us.
Maybe a hundred times as much genomic material as our own biology.
Maybe a lot more than that.
So a hundred trillion organisms living in us at any one time and about a kilogram in
mass of microbial mass.
So there's that extra bit that goes from the genome to the metagenome.
That's all the bugs that live up with us.
But all those environmental influences that you mentioned,
including your differences in diet and your lifestyle,
that is all continuous interaction throughout your life.
So there's a conditional interaction between your genes, the microbes,
and the world that happens from the time you're born to the time that you die.
And those conditional interactions determine who you are.
Who you are is the result of everything.
And unfortunately, genomic medicine, it has some very powerful applications,
particularly in cancer medicine and things like that,
and rare diseases.
But in fact, for most people,
the environment carries much more power
in determining your future and your future diseases
than, in many cases cases your actual genome itself.
So your genes are not your destiny. They may predispose you to something, but it's the
expression of those genes that's based on what washes over them throughout the course of your
life. Sure. And we've got different sort of genomic potentials as well. So there are some people,
you can refer to them as Churchill genes. Winston Churchill
got a Nobel Prize, was Prime Minister twice, and he drank and smoked heavily every day
of his life until he was 90. And so we think about the Churchill genes, you know, we'd
all like to be able to do that. And he actually managed to tolerate that. So there are some
people that have very resilient genomes. It doesn't matter what you do, they still live
for a long time. There are other people who have inborn errors of metabolism. They tend genoedd sy'n hyderus, does dim pwysig beth rydych chi'n ei wneud, maen nhw'n byw am amser hir. Mae pobl eraill sy'n cael anafu mewnbwysedd mewnbwysedd, maen nhw'n tendu i fyw yn ifanc ac nid yw llawer
y gallech chi ei wneud amdano. Ac yna mae'r rhai eraill ohonoch, lle mae'ch genedlaethau a'ch
amgylchedd yn gwneud peth sy'n digwydd i chi. Ac mae meddygfa prysu'n ceisio
ddatrys y gestalt hwnnw, y cyfnod cyfan hwnnw, er mwyn gwneud rhywfaint o ddiweddau amdanoch chi fel the whole totality of that, in order to make some judgments about you as an individual
and how best to treat you going forward.
Treatment isn't just treating diseases.
It's also preventive medicine, right?
So it's modifying your lifestyle so that you minimize the chances of getting disease in the future.
Yeah.
So really this is a whole new way of thinking about health and disease based on complexity and based on multiple variables that influence how your genes are expressed into the current health state that you are.
And it's dynamic all the time, and it's changing.
And it's changing based on everything you do, what you eat, how you move, what you think, your microbiome, environmental exposures, what we call the exposome, what you're exposed to throughout your life.
And that, it seems like, is responsible for 90 to 95%
of all chronic disease.
It's not your genome.
And yet, we've never really been able to look deeply
into that until recently.
And I saw when I started digging into all this,
I was like, wow, there's like 37 trillion
per billion trillion chemical
reactions every second in the body. And I don't know who counted them, but it's taken a while,
but it's a lot of chemical reactions. We have a hundred thousand terabytes of data
in our microbiome alone. And, and, uh, and how does, you know, one doctor or one,
you know, practitioner ever come to understand how all those things relate to each other, how they connect to
each other, what to do about them, how to navigate that in a patient who's sitting in front of you.
It's not something we learn at all about in medical school. And so this whole field of
phenomic medicine is actually encompassing all the omics, right? Your genes, your metabolome,
your microbiome, your transcriptome, your proteome, all the omics, right?
And there's probably more.
Yeah.
I counted 257 things ending in the word omics.
Yeah, your immunome, right?
And all of those things are things that we have profound influence over.
And they're things that get deranged or dysregulated by how we live and what we do.
So it's a very empowering message, but it's also like daunting.
How does, how does someone think of like, oh gosh, you know, I go to my doctor and I
get my 20 lab tests or 30 lab tests and my chem screen, my blood count, my cholesterol,
checks my blood pressure, you know, my weight and that does a Kirsch exam.
How is that even coming close to figuring out what's going on?
And it's not, the truth is it's not.
We're looking for pathology.
We're looking for end stages of problems that are picked up by these tests.
And what you're now able to do and what you've done in your phenome center in Australia is
to help us to kind of map the landscape.
It's almost like a new frontier of how we should be looking at human biology, not through
the lens of diseases, but by the lens of the phenome.
So can you kind of talk about what is the human phenome and how can we use it to guide
a more personalized approach to healthcare that's not a one size fits all issue?
Sure.
So as you point out, there's a lot of things you can measure, literally millions of variables
about the human body that are measurable now
In the real world which is where that quote and not everything that can be measured matters not everything that's measured measured matters
So it's like what do we measure that matters? Yeah, exactly so
So that it's it's a it's a multi-step process. The first thing is we have
Extraordinary technologies now that expand almost every day.
So the number of things that we can measure about the body, the number of ways we can describe the body in, let's call it, a multivariate biology space. So there is a mathematical part of reducing this data set into something that is more manageable. But all of the different technologies are not really practical for the clinic or a doctor or even a major hospital.
We're in the process of discovery at the moment,
and discovery leads ultimately to translation, which is what we want.
So our Phenoma Centre, which is a collection of very expensive instrumentation
designed to discover new human biology through chemistry, gynllunio o leiaf o ddiddordeb, sy'n cynnwys ymchwilio
biologi ddewis newydd drwy chemaeth. Ond hefyd, rydyn ni'n ei wneud ar gyfer
llwyth o ddwylliau, felly gallwn edrych ar ddau miliwn, tawadau o ddau miliwn o bobl
os yw'n bwysig. Ond rydyn ni hefyd yn bwysig ar hynny, unwaith ein bod wedi ymchwilio o'r miliwn o bethau
rydyn ni'n eu mesur, y 200 neu bethau neu hyd yn oed 50 o bethau sy'n newydd sy'n hynod o ddysgu am
y biologi, y sefyllfa y byddwch chi'n ei wneud neu'n ei golygu, yna i wneud
technolegau trawsnewidol newydd o hynny, a all eu datblygu mewn clinig neu hyd yn oed yn
y dyfodol mewn gweithredwr. Felly, rydych chi'n cymryd y maes fawr hwnnw o biologi dynol, potentially in the future in a doctor's surgery. So you take this vast space of human biology,
describe my chemistry,
you find statistically what the most important things are,
and then you create a new mini-technology.
So it could be a lab-on-the-chip sort of technology,
it could be even a dipstick, which measures a new metabolite,
or we use a lot of spectroscopic tools,
miniature spectrometers which you could
which cost a fraction of the discovery technologies which you could deploy in a clinic it reminds me
of like coloring books i have another kid where you had to connect the dots and there's all these
random dots on the page and to link them up together and these oh this looks like a duck
yeah this looks like a boat right and that's what you're doing you're seeing all these random
literally dots of biological data yeah and you're connecting them to see where they're related and how they influence disease and
what to do about them so that that so that's absolutely true right but uh your analogy is
slightly simplistic in that in that the duck is covered in a lot of other dots which are irrelevant
right you don't know that when you're measuring them so so the art and the science and the mathematics is designed
to extract the shape of the duck from the background of the noise.
I'm sure this is where AI and machine learning comes in.
Well, AI isn't, well, we used to, we've been doing this for sort of, I've been doing
this for 40 years now. I didn't call it AI then, we call it AI now, but multivariate statistics. AI is a way of doing multivariate statistics.
So AI is not new.
It's just we can do it better now.
Yeah, we can do it better.
I want to tell you about an area of longevity science that I'm personally really excited about.
Anyone in their 30s, 40s, or beyond should learn what
senescent cells are. Because if you let them accumulate in your body, you're setting yourself
up to age poorly. Senescent cells are also known as zombie cells because they're old cells that
linger in your body long after serving any useful function, wasting our energy and resources. Now,
in your 30s and 40s, it becomes harder for your body to eliminate these old, useless cells, leading to many age-related challenges like slower workout recoveries,
joint discomfort, and diminishing energy levels associated with feeling older and past your prime.
Luckily, there are naturally derived vegan ingredients that you can add to your diet
to help eliminate senescent cells. And there's a clinically tested formula that combines nine
of these ingredients to help
you eliminate your zombie cells and help you feel years younger fast. It's called Qualiacetylitic.
Qualiacetylitic packs nine vegan, non-GMO, gluten-free ingredients into one effortless
formula to help stop senescent cells accumulating in its tracks. With ingredients like fisetin,
piperolongamine, senactive, and many research-backed
all-stars to help eliminate senescent cells that can make you feel old before your time.
I have profound appreciation for the team behind Qualia Sinalytic. They're an exceptional blend
of doctors and scientists who dedicate significant time and effort to crafting high-quality products.
Their commitment to excellence and thorough research truly sets them apart in the field
of health and wellness. Try Qualia Sinalytic at qualolife.com slash hymen backed by a 100-day

when you think about the complexity, right? And you think about the amount of data we have.
And, you know, we now actually can measure a human genome pretty affordably.
We can measure the microbiome to, you know,
tests that you can get through various functional medicine and other doctors.
I just did a panel the other day.
It was a metabolomic panel.
It was a commercial lab that just sent me out a kit to draw my metabolome.
And these things are starting to kind of hit the consumer health market.
They're quite not in the doctor's office yet,
although some genetic testing is.
But I find that if we really look at disease,
what we're actually doing in medicine today
is waiting until people have something serious
or something that's measurable on a pathological basis.
And we know, and this is from my original textbook in medicine
called Robbins and Cotran, The Pathologic Base of Disease,
it says every pathological change,
anything you see on a microscope or on an imaging scan,
is always preceded by some biochemical change.
And what you're looking for is these early
biochemical signals that precede disease and the patterns in that data that can tell you about that
particular person's unique thing. And I believe it's going to blow up our whole notions of disease
because through the lens of systems biology and systems medicine, which is essentially what you're
doing, it's what we try to do at the Institute for Functional Medicine and with functional medicine
is apply this, take the learnings from the work that you're doing and others to try to kind of say, okay, where can we kind of try to accelerate the adoption without hurting anybody of this medicine to help understand these patterns in the data?
And so I wondered if you kind of talk about how we begin to kind of sift through all that because you know um when i when i when i look at a patient
i do a lot more in detailed analysis of lab testing but it's still just on the surface right
and and i'm just so excited for the moment when we'll actually do these tests at scale
see these patterns that are happening for you and realize that we're all different in our
manifestation so two people with depression or two people with Alzheimer's or two people with autism or two people with autoimmune disease
or whatever, diabetes, are not the same. And we're treating them all the same today in medicine. This
is where precision medicine comes in. So how does the role of doing some of these diagnostics, like the metabolome, the microbiome,
how do we start to think about learning from this?
And what are you learning in your research
that can actually start to make sense for people clinically?
Yeah, well, let's just start going on a little bit more
about the precision medicine aspect first.
I mean, the idea of one-size-fits-all
comes very much from the pharmaceutical industry.
Yeah.
Right, the blockbuster drug.
And this is not that long ago.
25, 30 years ago, drug companies were trying to discover that drug which they could treat
everybody with ulcers, everybody with arthritis, whatever, and find that drug which is a $10
billion a year thing.
And we know that's difficult to do.
And actually, all the easy ones have been found.
So the pharmaceutical industry is in a bit of a hard place now
because it's looking still for blockbuster drugs
and they don't really exist so much anymore.
And in fact, precision medicine is the opposite of that.
We're trying to divide people down.
And actually, ultimately, we're all individuals.
There is an exact treatment for you, right,
irrespective of what disease you've got,
because of your background physiology,
which is made throughout the whole of, creates it throughout your life.
And the pharmaceutical industry is not interested in that
because it cannot make vast amounts of money out of one chemical product.
Right, right.
But on the other hand, we still have this enormous task of measuring all of the things
that we need to measure.
And one of the reasons I spend a lot more time working on metabolism is that the metabolic
phenotype is actually incredibly useful because it captures a lot of the gene environment yn ddefnyddiol iawn oherwydd mae'n ddod o hyd i'r nifer o'r cyfranogiadau genhedlaethol genedlaethol
sydd angen i chi ei wybod am ddysgu cymhwysedd, am atal iechyd, atal ymddygiad, a
am ddatrysio cleifion pan fyddant yn cael ymddygiad. Felly, mae fenom yn y
chyfranogiad ymlaen o'r holl gyfranogiadau genhedlaethol genhedlaethol o ran pethau y gallwch is the expressed output of all the gene environment interactions in terms of things you can physically measure.
So your height and your weight, you know, phenomic properties,
but so is your blood cholesterol, so is your urinary creatinine,
and literally a million other things as well.
All of those things...
Probably a billion.
Whatever it is, it's a bigger number than you thought it was.
Maybe a trillion things.
But the important thing is you don't have to measure a billion things or a million things
because there's a lot of redundancy in the data.
So there are things that one metabolite might capture.
It might capture the information that you need about a whole pathway or one or two metabolites.
It becomes the ratios of those things that tell you about differential activities.
So what we call now artificial intelligence or pattern recognition methods are actually
designed to extract those principal features in the complex data set, multivariate data
set, and say, well, of all the things that you've measured, it's these 15 or 20 that
describe pretty much all the biology, the've measured, it's these 15 or 20 that describe pretty much
all the biology, the difference between a normal person and a person with a particular
sort of disease, or all the different subtypes of a particular disease.
And it might not be things we're measuring at all clinically now, right?
Most of it you wouldn't know.
Right, like David Furman, the 1000 Immunome Project, which basically got a thousand people,
look at their cytokines and their immune, he calls it the immunome and found that they were four cytokines, four markers that I never heard of
that are, you know, probably buried in my immunology textbook or maybe discovered after
I graduated medical school. And that they were highly correlated with advanced aging and chronic
disease. And, and those things now can be available as a clinical blood test, which you can use to track
over time.
You know, I was talking to Richard Isaacson
last night, who you might know is an Alzheimer's
researcher, who's doing a lot of innovative work
around a systems biology approach to Alzheimer's.
And he said they've come up with this new
diagnostics called a P, I don't know, something,
something, P tau, some number, I don't know what
it was.
But he said it's like a biomarker that actually found changes as you change people's lifestyle
habits that affect their brain.
So you can see the increasing or worsening of Alzheimer's or the improvement in Alzheimer's
through this biomarker.
But he might have looked at a thousand things before he came up with this one thing.
So that's what you're talking about is signal from noise.
How do you detect the signal from the noise?
Absolutely so. So, and the answer is statistics and a lot, a very large N,
right? So you have to be able to sample. N would be a lot of people.
N is the number of people. Yeah, N for number of people.
In order to make these sorts of discoveries, you really need to be looking at thousands
and thousands of people to build the basic mathematical models. That's for most diseases.
I mean, if it's a rare disease, I mean, or an inborn area of metabolism,
where the number of people might be very, very small,
but the effect is very, very large,
so you don't necessarily need a big N to discover what is wrong.
But for most diseases, things that kill most of us,
then you do need literally thousands of people to make those sorts of discovery
using the appropriate
sort of technology. And what's the appropriate technology? Well, it's one that gives you the
right answer. And unfortunately, there's quite a lot of different technologies. So you have to look
at thousands of people with a number of different technologies to do the sort of discovery that's
necessary to be able to refine out of that the small number of markers that you could then
productize if you like because ultimately it's a commercial angle on all of these things anything
that's going to be successful clinically and in the in the big world will have a will have a
commercial angle to it because somebody's got to validate it and it's got to be made and manufactured
so tolerance etc etc so when we think about precision medicine and the sort of discovery biology we need
to do, we need to think about all the possible problems that are going to come up in order
to make that work in the real world.
So you have to take a very long view into the future about what's going to stop.
So I've got this great new marker.
Is it going to be practical to measure it in the real world?
Is it going to cost $15,000 per time you analyze it?
And if it is, it's probably not going to work generally.
If it's going to cost $5, then you're talking business.
So we're looking for that magic bit that's not only good science, good biology, and good medicine, but it's also cost effective.
Yeah, it's true.
I mean, and I think we're well on the way to doing that.
It's amazing how much medicine has changed
in the last even decade. When I graduated medical school, we hadn't even decoded the human genome.
Sure.
Now, we not only can decode the human genome, but we can do large throughput analysis of just
tens of thousands of molecules that are in our body and you know like
just people don't even understand that that probably half or a third of the metabolites in
your blood are from your microbiome right so like wait a minute you're gonna check your poop by
checking your blood and it's like wow this is such a different world and and it allows us to sort of
look at this continuum phenomenon you know the uh 2009 2009 White House, sorry, the 2009 Whitehall to Courage study was published
in The Lancet, looked at a whole series of factors that we could look at that would precede
disease.
So what were the sort of predictive things that you can actually measure that show what's
happening?
And one of the things that they found was that high insulin levels precede high glucose
by as much as 13 years.
So doctors just check glucose.
And this is something that's sort of an easier thing to understand for people.
And they check and it's like, okay, well, your blood sugar seems all right.
I must, you must be all right.
You don't have diabetes, fine.
But the insulin levels go up before glucose.
And I've seen this for decades because I measure insulin.
But it's less than 1% of doctors that measure insulin.
Right, but it's actually probably one of the most
important biomarkers.
Now there's a new, and you mentioned the ratios,
there's a new test that's been now developed
that looks at insulin and something called C-peptide,
which is sort of a precursor molecule for insulin,
and the ratio of insulin and C-peptide
through mass spectrometry, which is
a very, very accurate test. And that test is highly predictive of someone's degree of insulin
resistance, which is one of the biggest drivers of all chronic disease. So this is something,
you know, one of the tests that could be like more like five or $10 that tells you a lot that
kind of the other data might not be as important. Can you kind of talk more about this whole idea
and what you're finding around this continuum concept of disease
from optimal health to pre-symptomatic disease
to symptomatic to full-blown disease to death?
Yeah.
So the idea is that we all can be considered to be existing.
And the reason I'm asking you is because I think phenomic medicine
is the first time we've been able to think about actually looking at that continuum. Because doctors don't do that. They
just wait until you've got something, and then they treat you. Well, and doctors are very highly
siloed, you know, gastroenterologists, nephrologists, neurologists, and stuff like that.
But that's one of the things that systems biology really teaches you, is that all those things are
connected together. And it's very difficult to look at a patient just from one
medical angle there'll be other things that are connected you know the organ systems in the body
don't work in isolation they work together as part of the system the immune system connects
everything together so looking at the multi-systems is uh is is very uh important um but so from our point of view,
we tend to think in the way we conceptualize it,
it's thinking of people occupying a metabolic space
or a phenomic space.
It doesn't just have to be metabolites,
but I tend to measure metabolites a lot.
So we think in metabolic spaces.
So what I mean by that,
so if you've got, say, three parameters from your blood,
you have glucose, creatinine, and u urea you have a three-dimensional space. Yeah be your urea creatine glucose space
But of course there's thousands and thousands of things you can measure so you can have thousand dimensional spaces and you occupy
I took a blood sample from you now you would occupy a particular plate position in space
And so would I and it wouldn't be the same space. We'd be separated by some
Hyperspace difference and then tomorrow morning it might be different in space and so would I and it wouldn't be the same space we'd be separated by some hyperspace
difference and then tomorrow morning it might be different oh yes what we'll do is we will be
hovering around in our own within our own metabolic sphere if you like except the sphere isn't in
three dimensions instead of 10 000 dimensions so think about us oscillating that during the day
and you are oscillating in your space and your space and my space if we're both healthy we'll
be fairly similar as soon as we get a disease we're going to move in your space, and your space and my space, if we're both healthy, will be fairly similar. As soon as we get a disease, we're going to move in the space,
because the different parameters are going to change. So the sort of advanced mathematical
tools, including AI, are about looking at where we are in that space, the particular markers for us
that make us unique, and also how that changes in time and that's what that is but essentially what what we
do so we build spaces in m dimensions large number of dimensions and we look about how a disease
impacts on that occupancy space that position in space and we look at a disease as a process of a
movement a trajectory through space so you start in space, let's call it your healthy space,
which you're hovering around a bit in.
You get some disease and you move significantly in space.
And when you recover, you should go back to where you started.
Now, this is quite interesting conceptually.
And interestingly, we've learned a lot from studying COVID
over the last couple of years.
COVID has been the
biggest hit in human biology that we've had since the flu in 1918. That's a giant
synchronized hit in human biology. So that produces population level effects that we can see.
And one of the things that we observe from a metabolic mapping point of view is when people get COVID-19, we've now got a lot of
data on this, is they move in metabolic space. They actually move in lots of different dimensions.
COVID affects a lot of organs, makes it really interesting for people doing metabolism.
It is non-obvious. But not for people who have it.
Well, I've had it a couple of times. It's no fun, I can tell you. And then the idea of mapping that movement into the abnormal space,
which is a highly inflammatory space,
and then mapping the movement as you recover back.
Now, as we know with COVID, a particularly interesting example
is because a lot of people don't recover.
They end up with something called long COVID or post-acute COVID-19 syndrome, where they're actually physiologically abnormal.
And then we started thinking about the ways of measuring that.
We've done a lot of work on this.
But we also started thinking about it from the point of view of reinfection, because there's been lots of reinfections.
People have it three or five times.
And the more times you have it, the more times you're more likely are to get long COVID it's cumulative so what we think about this now and I think this is relevant for
all of human diseases let's say all most I haven't studied all human diseases but let's say a large
number of human diseases is they can be considered as miniature each time you get a disease and it
can be different diseases you
have a little journey in metabolic space from your normal space into abnormal
space and then back again the important thing is when you come back to your
normal space you don't come to it back to exactly the space you started yeah
you shift slightly and the effect of that over your lifetime is aging so
you're metabolically aging through a series
of trajectories. And the important thing is there are now omics measurements that you
can make that map that space, and there's mathematics for reducing it. So we can start
thinking about localized journeys due to an individual episode of a disease, and also
potentially lifetime journeys as you
age and become sort of more biologically incompetent as you get older, which is the aging process.
I mean, aging is not a disease.
Aging is natural.
And death is the thing that we all worry about, but it's premature death is what we're trying
to avoid through our technology. Precision medicine is effective
like trying to avoid premature death averaged over the whole of your
lifetime. You brought up something really interesting. You said aging is not a disease, right?
But neither is having a high
insulin, but it definitely drives disease. So where
on that continuum do you sort
of name the disease and we have these arbitrary cutoffs if your blood sugar is 126 you have
diabetes if it's 125 or 24 you don't well we know just that's ridiculous right so it's also
population specific i mean or genetically what's true of japanese isn't true for sure for sure for
sure so we have like this sort of arbitrary cutoffs where we say you now have entered into a disease.
But this phenomenon, this continuum of dysfunction in aging, for example,
is that there's breakdowns as normal physiological processes that don't manifest as a disease,
but that make you get biologically older.
So we now know there are interventions that you can do to change that trajectory.
So in a way, a lot of people are talking about aging as a disease and treating it as a disease
and understanding the underlying mechanisms of, they call the hallmarks of aging, for
example, the things that happen that are in common with people as they age, like mitochondrial
dysfunction or inflammation or change in the microbiome or epigenigenetics, or telomeres, or zombie cells.
These are things that we don't really typically measure
in traditional medicine, but we can now.
We can start to look at these things and see,
okay, well, if I'm doing these five lifestyle things
or taking this supplement or this drug,
I can reverse my biological age.
And I just did this.
It was so fascinating to me.
And I still kind of worry about the validity
of some of the tests and the reproducibility,
but I did this lab called True Diagnostic
where they do biological DNA methylation testing
so they can look at your biological age.
And I did it two years ago.
And then I was 43.
I mean, I was 62 at the time.
I just did it, and I'm going to turn 65 this year
in a few months, and I'm 39.
And I did a number of things on purpose to see if I could move that, right?
So I changed what I ate.
I changed my supplement regimen.
I added rapamycin, which I don't recommend everybody take.
I'm a guinea pig for myself.
I tried various technologies like plasmapheresis to clean my blood.
I did a number of different therapies to see if I could move it.
And it moved and it
wasn't i wouldn't say you know having a biological age of 43 at 62 was bad it wasn't a disease
damn good right but what was i more on the continuum towards disease and breakdown
at 43 biologically than i am at 40 39 i think so right and so that's fascinating to me it's like
i'm not treating i wasn't treating a disease by doing these therapies. I was trying to optimize
the status of my phenome, essentially, right? And that's what I think is super exciting,
is understanding this concept of the exposome. So maybe you can just take a few minutes and
help people understand how much control they have over what happens to them in their life
through their health, and understanding through the lens of the exposome and how that interacts
with our genome and our microbiome and you talk a lot about that yeah um you well let's start with
microbiome which is probably the most complicated part of it so microbiome develops from the time
that you're born uh you are pretty much a pretty much aseptic before you're born.
That's not absolutely true.
We know there are bugs that live inside you even when you're in utero.
But you get a lot as soon as you're out in the big, wide world.
And that changes very rapidly over the first six months of life.
The microbiome fully develops.
It doesn't become like an adult microbiome until about three.
It takes about three years to mature even the microbes in you. And it's that early microbiological
development that tunes your immune system. So your immunology is set up from the time,
the first year or two of life. And in fact, when it comes to understanding long-term chronic disease,
a lot of the stuff that we've got to fix is in those first two or three years. If those are bad
years, then you're never going to be able to fix it, right? So I don't think there's that
appreciation of the importance of having a healthy, very young childhood with the right sort o'r dechrau bach gyda'r cymdeithas cymdeithasol, gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol,
gyda'r cymdeithas cymdeithasol, gyda'r cymdeithas cymdeithasol, That's part of building up your long-term immunity and part of building up your long-term metabolism.
And all of these developmental processes have metabolic signatures that go with them.
And in fact, they turn out to be some of the easiest things we talked at the beginning
about.
There's so many things you can measure.
But in fact, we would say that of all the things you can measure, metabolic profile
is probably the easiest.
You can get urine samples.
You can get blood samples very, very easily. Those are easy samples to get. It's what clinicians look at all the things you can measure metabolic profiles probably easiest you can get urine samples and get blood samples very very easily
There's a easy samples to get what clinicians look at all the time
So a lot of our technology is geared to getting the diagnostic and prognostic
Features out of things that are readily clinically available and if not non-invasive then minimally
Invasive so again part of the science is mapping those sorts of changes in metabolism, in urine and
plasma, peripheral fluids, if you like, back to much deeper things that are happening in the
microbiome, your immune system, and actually also its organ-specific physiology and pathology,
which develops over years. And it's really all the things that we do that affect this this interaction, right? It's what we eat
It's exercise. It's our thoughts sleep. It's environmental toxins our microbiome. It's
Yeah, I mean temperature climate weather everything and when I put my health care hats on I mean, it's the simple things that are
Important so we talk about all these incredibly expensive and complex technologies.
But common sense is important too. So the single best thing that you can do for your life is have a healthy diet
and do a reasonable amount of exercise.
If you look at WHO statistics,
the biggest single killer of humans is cardiovascular disease statistically 80 percent of premature
death due to cardiovascular disease is preventable by healthy diet and exercise and not smoking
those are really 80 percent of the world's biggest killers and that's changing the exposome
that's right exactly yes exactly so you're basically talking about things we have in our
control which is a very empowering message yeah and you know it's like not like we're waiting for That's right, exactly. Is part of the exposure. Yes, exactly. So you're basically talking about things we have in our control,
which is a very empowering message.
Yeah.
And it's not like we're waiting for some big gene discovery.
We're going to get a gene splicing editing technology
that's going to fix us and prevent us from being sick.
That's a long, long way away from now and may never be possible.
No, because most of these conditions are polygenic, right?
Absolutely.
It's not just one gene, like Down syndrome gene,
which could be affected, or if you have Huntington's chorea
or some rare condition like muscular dystrophy, great.
You can edit your genes out.
But most of the stuff people are suffering from is just polygenic.
It's complicated, and it's influenced by our environment
more than the genes.
Absolutely.
And what I'd love you to do sort of next is to help unpack
the story of long COVID.
Because this is something you focused on with your team.
And it's an application of phenomic medicine that I think has real fruit to bear.
I mean, I'm a practicing physician.
I can tell you I see a lot of cases of long COVID.
It's not a rare problem.
And there are long COVID clinics in medical centers all across the country that I personally think do a lousy job of actually helping people because they don't understand the condition.
They try to medicate the symptoms, but without really understanding the biology of it.
And I think we are seeing data emerge around the biology of what's happening. But it's not stuff often you can get within sort of an average doctor's visit or, you
know, into looking at sort of anti-muscarinic or autoimmune antibodies or various kinds
of cytokines or various biomarkers that are elevated.
And with the phenomic medicine that you're doing, you can sort of take this almost novel
condition and say, what does it look like?
What are the things that go wrong?
How do we start to learn about why this is happening and what we can do about it? So
can you tell us a story about how you're using long COVID as a way of really applying phenomic
medicine and what you're learning from it and what you're seeing, the patterns are that you're
finding and what are the therapeutic sort of hopeful things that we see on the horizon as a
result? Right. Again, a lot of stuff to ask.
I know. I ask long questions. I'm sorry.
I want to know everything.
My mother always asks me, you know, not what I learned in school today,
but what questions did you ask?
So I've been in the question business for a long time.
Fair enough.
So if we just think about that,
from the point of view of my laboratory, there's peculiar bits of history here. I was
previously, as you know, at Imperial College London. About
five years ago, we moved to Australia. So we can basically expand
on the phenomic medicine
program and build a new phenome center, really just to look at that.
Our new laboratory our new laboratory
new laboratory was it was it was opened in october 2019 you think about that where we are in relation
to covid it's like three months before holy cow it's good timing so we we sort of put this this
50 million dollar laboratory together and then we're looking for things to do and covid appears
and when you when you build expensive laboratories,
you need to do important things with them.
So we had a whole list of things, you know, cardiovascular disease,
diabetes, and all the other stuff.
And then COVID just went to the top of the list.
So our approach to the problem was to work with international collaborators.
And Australia, as you may recall, was one of the last out the gate with covid
because it's quite geographically isolated and also they had we could from australia we could
watch it happening across the world australia shut down fairly quickly to get in or out and it
basically prevented the disease in for a couple of years it kept pretty much kept it out and
australia still has the lowest mortality for COVID
than any other country in the world.
It's quite extraordinary.
But so we started to build all these databases
based on stuff from Harvard and Cambridge
and all the other stuff.
And we were studying, of course, initially the acute disease.
But to understand long COVID,
you have to understand the acute disease
and what it can
do first yeah and the first thing that comes out of it is it's incredibly heterogeneous so covid is
is heterogeneous in its expression in human populations there are some people that get
incredibly let's just go back to the original wuhan variant if you got you got people who had
incredibly severe respiratory disease
that would put them from catching the bug to going into intensive care in a week or
less than that. And once you're in intensive care, you're in deep trouble, as you know,
you don't have a place to avoid. And there are other people exposed to the same genetic
subtype of the bug that have almost no effects. So you have this diversity of severity, and that still persists.
And symptoms.
And symptoms.
So you can have respiratory symptoms.
They were more important earlier on in terms of severity.
But there's neurological symptoms, there's GI symptoms, there's kidney.
Blood clotting.
Yeah, blood clotting, skin lesions in children,
cow saccullike disease,
a whole range of things.
Almost everything that you could think of.
For me, anecdotally, it's a lung disease.
And I was thinking, what does urine teach you about lung diseases?
Not necessarily that much.
And then we looked at the first samples we saw from COVID, which would have been
probably March 2020. It lights up everything. I've never seen anything.
Urine.
Urine or plasma. I've never seen anything that lights up the body like this. I thought,
well, you know, we've got a big story here.
So what do you mean lights up the body?
I mean, every pathway was abnormal, right? So there were things related to renal metabolism, liver metabolism.
There were changes in lipoproteins.
It's just wherever you looked, wherever you looked, there was alterations.
Whichever technology you used, there were things that were different.
Normally, you think of trying to find the right technology to get the right diagnostic.
But because this is such a spectacular systemic disease,
and in fact, you know, the essence of the disease
is really its systemic involvement and its immunological involvement.
And so we asked the question,
if you've got all these sub-effects in renal liver,
microbiome is altered as well,
how do you know when it's over
right it's not when you stop coughing of course some people didn't stop coughing right but uh it's
not when you stop coughing it's when your system by chemistry goes back to normal so we got samples
from people who'd had this this is now a year or two later and we start to look at people with long
covid people who for instance people who had never been hospitalized that had COVID once, and we
had that in Australia, we had pretty good control of that because of the way that the protection
was politically implemented in Australia. So we ended up with people who only had mild infection,
never hospitalized. But if you look at their biochemistry, they were still abnormal six months or a year afterwards.
So a whole series of things that were different.
Just the people who had long COVID or everybody?
No, no, these were everybody.
Anybody.
Anybody and everybody after COVID.
For some biochemical features,
there are things that do not return to normal even after a year,
even if you have no symptoms.
Wow.
And we call that occult long COVID, right?
It's something that's hidden.
Are you saying this is 100% of people that you tested?
I think there will be 100% of people, ultimately,
that have some long-term biochemical effects
of having one infection of COVID,
even if they weren't ill to start with.
And also, somewhat alarmingly,
this appears to apply to children
as well. So, I mean, if you recall, Donald Trump famously said, you don't have to worry about
children. They hardly get it because, of course, he was an expert on many diseases. But that's
actually not true. There are physiological effects in children which are potentially quite serious.
So, what we had was a whole series of different metabolic and immunological biomarkers which indicate different subsystem failures,
different organ failure, different levels of severity, etc. So we can take a panel of those
and monitor anybody from their blood actually, or their urine, but the blood is easier in this
respect, For functional recovery
for kidney, gut, you name it, whatever it is, there are biomarkers which have to
normalize. And these aren't the normal things you get on your blood panel when
you go to the doctor, right? There are a few things, but only a tiny percentage of
them. So these are, a lot of these things are things that we discovered in our
lab and other people have discovered them and verified those as well. So what
we're thinking about now is taking a blood sample and from that metabolic panel, metabolic profile, we can say, well, look, whatever your
symptoms are like, it looks as though you've still got liver damage or you've got new onset diabetes,
which is a common effect. And long COVID is not really a disease in its own right. It's a collection of other diseases that we already know that have been accelerated by having exposure to COVID.
And the important thing about that is, and this is also a hopeful thing, is if we find those markers of your disease, of your subset of long COVID, from a blood analysis, we say, well, okay, you're a diabetic now. You need to have the
medicines already available for that. So this occult long COVID where you don't necessarily
have to have symptoms associated with it, in most cases, they're things that are, you've gone from
pre-disease into a disease state, accelerated by COVID, or you've gone into a pre-disease state.
So again, an accelerated- That's terrifying. Yeah, it is terrifying. But the important thing is you can do, if you've gone into a pre-disease state. So again, an accelerated... That's terrifying.
Yeah, it is terrifying, but the important thing is you can do, if you know it, if you've been
screened, you can do something about it because there are already lots of therapies. The things
that we don't know so much about, although we know we are learning about them from the
biochemistry, things like the neurological effects, right? So there's a lot of neurochemical effects.
The brain fog and the-
Well, which is also is a really common part of long COVID,
right, chronic fatigue.
And in fact, so here's another sort of bright side
to the story is that COVID is now shining a light
on lots of diseases that we already know,
but we find new things out about those diseases
because COVID has accelerated
them in particular people that didn't have them before. So if you look at chronic fatigue,
there is a set of chronic fatigue syndrome. There's a syndrome which is usually without
an etiological agent. Most people agree that it's probably a viral origin, but we can be pretty much
certain of that with COVID because people get this brain fog and other neurological problems as a result of COVID.
We know what that etiological agent was.
And there are molecular biomarkers that go with that.
They go with brain dysfunction.
Well, one of the ones that we think is really interesting is the tryptophan-kynurenine pathway.
And that's got a lot of the tryptophan-related metabolites and neurotransmitters.
There's a whole range of things.
Serotonin.
Serotonin, yeah, for instance.
And that pathway is really, really disturbed.
It also is one of the ones that stays disturbed for the longest after you've had your COVID infection.
And so we're thinking about what this is about.
And by the way, when you go to your doctor, you're not getting your tryptophan and urinate levels measured,
but you're looking at these things with your deep phenomic analysis
and you're seeing that, oh, this seems to be a persistent pattern
in these patients.
But if you look at that pathway and things that are disordered
in that pathway, there's actually loads of diseases.
Huntington's disease, there's Parkinson's disease,
there's HIV-induced dementia.
All of those things have got defects in the tryptophan, kynurenine pathway.
This is a really long list of diseases.
And that's actually something that we think is probably important for medicine in general,
that irrespective of all the other stuff,
measuring that pathway is actually deeply insightful for a lot of diseases because it's because it's it's the thing that responds
and gets worse when there's inflammation from any source yeah whether it's covid or whether it's
sugar and that's because that pathway is very the the enzymology if you like is very
immunologically controlled so so for instance things like things like TNF-alpha, interferon, gamma, et cetera,
stimulate the indole dioxygenase enzymes, which convict...
IDO, right.
Yeah, exactly. The IDOs, exactly.
So the tryptophan to kynurenine transfer is very much modulated by that,
those immune factors.
Just to break that down a little bit, so we can...
Because not everybody's a phd in biochemistry the phenomenon you're talking about is inflammation interferes with a critical
enzyme called ido it's called ido that is involved in taking tryptophan from your diet from you know
turkey or whatever you're eating and converting it into serotonin. And when there's inflammation, that process is affected and you end up creating molecular
byproducts that are quite toxic to the brain, like quinolinic acid that create inflammation
in the brain and can cause any host of neuroinflammatory diseases, which range from
autism to Alzheimer's, from anxiety to OCD, all of which are brain inflammation conditions.
So there's a final common mechanisms and pathways, but a variety of insults, right?
Because inflammation can come from your microbiome.
It can come from COVID.
It can come from sugar in your diet.
It can come from a million things.
So I think this is such an important thing that you're bringing up, which is that there's
a lot of stuff that we've never looked at that is where the problem is.
You know, there's a joke that I often tell when I'm giving a lecture, which
is this guy's looking at on the street for his keys under this lamppost and his friend
comes by and says, what are you doing?
He said, well, I'm looking for my keys.
He said, where'd you drop them?
Well, I dropped them down the road.
He says, why are you looking over here?
He says, well, the light's better.
So we're, we're used to looking where we can see the light, which is our typical chemistry
and blood count.
But it's actually not where the problem is.
And with phenomic medicine, we're actually, for the first time, able to shine a light on a lot of other things that we didn't ever look at before in the history of medicine that can now help us predict what's going on.
I mean, the thing you mentioned there, quinolinic acid, that's a really interesting metabolite.
It's massively elevated when you actually have the active covid infections
That's also the end. It's sort of quite a few steps away from tryptophan
Quinolonic acid is used as a striatum straight or neurotoxin an experimental one in rats
Really if you dose rats with quinolonic acid you can make experimental Parkinsonism. Well, that's pretty worrying, isn't it?
So this is how an infectious disease can lead to something totally different downstream
as a complex interaction, which is immunological.
It's also dietary related, depending on, and also potentially microbiome related,
because the microbiome has a lot of activity in that pathway too.
Yeah, it's amazing.
And what you're talking about is all these overlapping
diseases that seem to be separate, right? But actually have the same underlying common
mechanisms, but just manifest differently in different people depending on their genetics
and predispositions and how their body uniquely responds to it. So this is really what we're
talking about around precision medicine. Well, that is systems medicine to me. Systems
medicine allows you to visualize the complexity of it
so that you can be more efficient and precise in your interventions.
That's right.
It's great.
It's amazing.
And you talk about this sort of patient journey phenotyping
around COVID-19.
Can you explain that?
It's what you were talking about before,
tracking what happens over time
and if people regress to more of a normal phenotype.
Well, this is an
ongoing job it's a big job because you have to have to be statistically powered so what we're
trying to do is look at populations and the way that they respond to infections COVID is one of
them so if you we have there is lots of epidemiological studies where samples have been
collected for many many years framing and was the original one looking at heart disease.
There's a study in Western Australia called the Busselton Study.
It's a bit like Framingham where you're looking for heart disease and diabetes over a long period of time.
And we've had access to the Busselton Study.
So we already had run thousands of people from Western Australia who were part of the normal population.
So we're describing what normal Australian biology looks like, right?
We got a lot of beer in there.
Well, yeah, that is part of the metabolite in Australia.
Beer metabolites?
Yeah, yeah, yeah, fosters.
Yeah, but the, and so when you're looking at, so that's a reference point.
So usually you think about measuring, taking these samples to try and create new biomarkers for future events by studying the population over many years.
But we can also use the reference frame for the population biochemistry.
This is Australian biochemistry.
So when somebody's had a journey due to COVID, they go out of that space, and we can measure where they should be within the population by mapping them biochemically through time.
And in fact, we've just been given another million dollars by the state for extending the Busselton study
and resampling people now after their last something which is probably five years ago
because almost all the people have had covid right so we can measure the before and after covid
status and we can find all of those potential long covid people that didn't maybe the occult
long covid they don't even know they've got it and we can make medical recommendations how to
improve their health knowing that covid has had certain knock-on effects
in different parts of their their systemic metabolism so we're this is very to me this
is very real this is very translational so we we're also mixing for the first time i think ever
epidemiological studies with real clinical studies yeah real-time clinical studies where
we're monitoring trajectories of people in and out of the normal population, the normal population being defined by an epidemiological sample profile.
And so that becomes, and then to have that actionable,
so we can find people who have latent disease as a result of COVID or anything else for that matter,
and then saying, right, well, you need to go to the doctor and get this, this, and this tested and sorted out.
That is a very practical part of translational.
So what are you seeing with the data you're learning? Because you're doing a phenotyping
of long COVID where you're seeing these abnormalities that track across symptoms and
explain how people feel. And there are actually biomarkers that you can use to track the trajectory
of any treatment, whether you're not treating them or you're giving conventional approaches or other approaches, what kind of things are emerging that help you think differently
therapeutically about how to treat patients? Because it's not a single pathway that creates
a single disease with a single drug, right? It's a very different, you're talking about systems
medicine. So how do you start to apply what you're learning to patients with long COVID? Because
there's millions and millions and millions, anywhere from 6% to maybe up to 30% of people.
Maybe you're seeing 100% of people have asymptomatic long COVID.
Wow.
What do we start to do with that data?
Let's start with what the statistics are.
There are a lot of statistics around, a lot of studies now on long COVID. I think the correct number is about six to seven percent
of people have some sort of symptomatic long COVID, maybe at two years, even three years
now. And if you've got it at two or three years, you're probably not going to get rid of it.
It's become a chronic disease. So that's the first thing, is putting biochemistry around that, that allows
you to say, well, look, let's look as though you have long COVID based on this biochemical profile.
Now that's actually quite important to people because a lot of doctors, as you know,
do not know. Well, they say, yeah, well, you're feeling tired, you know, it's your age and it's
easy to dismiss. And that's what a lot of chronic fatigue patients have actually experienced.
I think it's a very poor response of the medical community that's what i had chronic fatigue syndrome and i had to
cure myself and that's how i learned all this it's it's it's miserable isn't it it's horrible
the worst thing you could possibly imagine it's like you haven't slept for three days
but you just woke up well i had i did i had long covid um as a result of getting covid in the first
wave i was one in the first wave.
I was one of the first people in Australia to get it
because I'd gone to a conference in Italy in February 2020.
Do you remember?
That was one of the first ones that kicked off.
And I came back so tired when I got back.
I must be jet lag.
It was jet lag that didn't go for three weeks or four weeks.
And two months later, with our own technology,
we diagnosed that I actually had had had covid
because my biochemistry three months after i'd had my episode was still the same as active covid
patients so so this liver the lived experience right gave me a little bit of insight into what
what might be might be going on but i can tell you you, I don't have to tell you, chronic fatigue is truly miserable.
Right, I mean, yeah.
Fortunately, I think I'm largely through that,
but it did leave me with diabetes.
So thank you very much.
Like type two?
Type two diabetes I was left with.
I also have atherosclerosis now,
which I didn't used to have.
Really?
And in fact, the cardiovascular side,
that's one of the, that's one of the-
Yeah, damage to your blood vessels. Well Well and there's very strong biomarkers for
that actually which is we're very interested in at the moment because we...
Like what? Well the apolipoprotein B100, apolipoprotein A1 ratio. So for
those that don't know the B100 is a transporter lipoprotein, a super
molecular complex that actually helps cholesterol
get into blood vessels.
This is ApoB you're talking about?
It's ApoB, yeah.
And so it's atherogenic.
And the A1 does the opposite.
So the ratio is actually very predictive of your atherosclerosis risk because it's part
of the active transport process of cholesterol.
But it's also an important long-term risk for myocardial infarction, stroke. So you're saying that ratio changed with COVID?
It's dramatically changed during the active infection.
This work goes back 30 years on the relationships between apolipoproteins um b1 uh and um and cardiovascular
disease um you go from being a normal person to being an intermediate to high risk within about
three days right of catching covid it really changes it's dramatic right and that then persists
for some time right and that's one of the things we monitor
in the long covid people is there a ba1 normal or abnormal and some people well of course if you're
as you get older your aba1 tends to you know get worse and it gets worse with um
obesity and things like that as well unsurprisingly um but covid causes an acceleration of that
enormously and when we were looking at samples from the uk and they the uk got it really really
bad the wuhan i mean they had people dying in the corridors and hospitals and stuff um the people
that were six months after their episode we still have people in ultra high risk
of cardiovascular disease
as a result of their COVID exposure.
So that's another thing.
So that's something that's,
the infection impacts on long-term cardiovascular health.
But there's a way of monitoring that.
That's something we could do now.
You can monitor all this stuff
and you see these changes. What treating it are you finding any therapeutic
applications of phenomic medicine in other words where you not just treat diabetes because you have
it after covid but where you can actually say gee there's these you know these auto antibodies for
example that are forming against your nervous system tissue which we now can measure um and
for example europe they're doing studies
looking at plasmapheresis, where they filter the blood, clean up all the antibodies and all the
crap from your blood and put in new protein and put back your cells. And they're finding
significant improvement. I've personally seen with my long COVID patients, it's one of the
things that really helps a lot. So I'm wondering if the biochemical profiles with the right therapies
could actually go back to a more normal pattern and not even the occult long COVID pattern you're talking about.
Yeah.
So all those things like plasma, phoresis, et cetera, I mean, it's difficult.
When you're talking about millions of people, that's not really very practical.
Not scalable, no.
Okay.
So for your patients, they're lucky, right?
Yeah.
And we're lucky actually in the West that we can do something about this in the
developed world um but there's a lot of people that can't do anything about it so um what was
so one of the things we're thinking about so let's just come back to tryptophan pathway for a minute
right there are drugs you know the uh indomethacin is a good old drug an ideo inhibitor uh it's sort
of banned certainly banned in australia because it causes problems long term sort of renal
insufficiency renal papillary necrosis and things like things like that but there are obviously once
you start to find particular molecular targets that are abnormal whether it's in covid or long
covid then you can think about drug therapy to selectively try and change change that but we
are actually interested in sort of dietary intervention
So for instance, you know that you get a lot of the you know
tryptophan etc from the diet is it just restricting tryptophan isn't is not the solution because one of the one of one of the
Effects of long code is actually having a low low tryptophan. Yeah, right
Anyway, and the part of that is because it's metabolism is accelerating
Just adding more tryptophan does not help especially if it's being metabolized to
quinolonic acid which is poisonous maybe b6 could help because it activates that enzyme indeed so
so again thinking about alternative drugs which we might use but also we found that there are
sort of natural inhibit there's several natural inhibitory natural products in certain foodstuffs in plants.
Phytochemicals.
Yeah, phytochemicals, exactly,
that inhibit some of those enzymes in that pathway.
And we haven't done it yet.
In the next year, we will do some sort of nutritional intervention study
where we're adding these phytochemicals,
all the original material.
It turns out that the plant sage has got high levels of these things.
So sage might be a natural, if you like, cure for long COVID.
But don't quote me on that because we haven't proved it yet.
But we're thinking about this in this holistic way.
You learn about the biochemistry, you think about, well, can you fix it with a drug?
Or can you fix it with a dietary intervention?
Life-solve diet, the exposure, right?
All of those, all of those.
Fixing your microbiome who
knows all these things can be start to be therapeutic tools and then you can track how
they're doing across this continuum to disease but the solution for you might not be the same
as the solution for me exactly because that's why you have to kind of map out each person's
individual exactly yeah kind of biology which is what phenomic medicine really is about it's
to me it's it's what i think is one of the most exciting areas in medicine which is what phenomic medicine really is about. To me, it's what I think is one of the most exciting areas in medicine,
which is finally the understanding that the way we're looking at disease
is so outdated based on individual diagnoses
that are all treated the same by conventional medicine.
And that these patterns in the data that you're seeing
with deep phenomic analysis, even within long COVID, for example,
it's not a uniform condition.
And different people have different manifestations of it. And the treatments are going to be different depending
on what it is rather than just a one size fits all treatment. So that's kind of the promise here.
I wonder, you know, how, how do you see this kind of one, five, 10 years from now? Well, like,
is this going to be in the clinic? Are doctors going to be doing this? Are we able to get
deep phenomic analysis of us? Cause I co-founded a company called Function Health,
which is essentially designed to get a deep phenomic analysis of each individual
and use sort of medical intelligence and computing power to help make sense of it,
like you're talking through math, right?
Yeah.
And we're going to get regular blood work now.
We're measuring ApoA and ApoB and all these things that we're talking about.
We're also going to be looking at your omics
and metabolome and microbiome, your genome.
We're going to be looking at biosensor wearable data,
your medical history, all that information
in order to help create a kind of predictive model
of where you're headed
and what you can do along that continuum
and hopefully get to 100 healthy years.
But we're doing it outside the healthcare system
because it's so hard to change things from the inside, right?
And people want it.
They want it on their data.
So where do you see this sort of going,
and how do we start to adopt this?
And you're doing a lot of the hard grunt work in the lab
over decades that they've gotten at this point,
but how do we get to kind of where this is available to everybody yeah so I was previously the head of
surgery and cancer at Imperial in a big clinical academic department which was
immense fun for ten years but I became limited so this isn't this is not as bad
as it sounds limited by the National Health Service so the National Health
Service is a fantastic institution I am a a big fan, right, because it does so much good for so many people
for no money, right, personally.
But it's also like a leviathan.
It's difficult to shift its direction, right?
And I became quite frustrated with that, and that was one of the reasons
I wanted to move to Australia to build a new lab more connected with Asia.
Wasn't it better weather?
The weather is truly extraordinary.
So it's 101 outside in Las Vegas today,
and that's pretty common for about three months in Western Australia.
But anyway, one of the things was to set up a phenome sensor
that actually was trying to address not just clinical problems,
it's on a hospital campus where our lab is, but also the epidemiological type problems,
but also diet, healthy nutrition as well.
So we're thinking about humans in the total environment.
And Australia doesn't have a national health service in the way the uk has and it has
a lot of linked hospital services but it's federally funded and it's very well funded from
the point of view of medicine so so one of the things that we wanted to do is have this more
holistic approach that we thought would be easier to implement in australia but we've already got
two i think two translational diagnostics that have
come out of the COVID-19 work that aren't actually really related to COVID-19 at all. So we've found
a better way of measuring ABA1 on a really small NMR spectrometer. So a lot of the work we do is
on these discovery spectrometers, which are $2 million each. Well, we've now got it working on a $100,000 machine,
which is still expensive, but the actual reagent cost is zero.
So it's radio technology, so it's reagent-free technology.
And we've patented that,
and we're now looking at translating these miniature NMR spectrometers
to the clinic for general cardiovascular assessment.
So that's a translational step.
The other thing is that's really fascinating and actually a discovery from acute COVID
is we found a load of really weird and wonderful metabolites initially in the urine,
but we found them in plasma as well, that are all cytosine derivatives.
And when you look at them, if you're in medicinal chemistry, you go,
you know, that looks like an antiviral drug, or that looks like an anti-cancer drug. We've now
found a dozen of them. They're completely new to human biology, right? Published just a couple of
months ago. And it turns out that they're part of an ancient immune system, the viperin, the
virus inhibitory protein mechanism that creates antiviral drugs when you have a virus infection.
Your own body.
Your own body.
And so the drug companies think they invented combinatorial chemistry.
Actually, nature did it about 3 billion years ago.
So we discovered a whole new piece of biology from COVID-19 urine patients.
And that turns out to be relevant for all viral infectious diseases.
There's now a urine test for active viral infection,
which comes from our work on COVID-19.
When I was at Imperial,
the head of intensive care came to me one day
and said, you know, if you've got a test
that could distinguish people of active viral infections
versus bacterial infections, that would be really useful.
Because at the moment, we've got to do lots of different testing
sometimes a day.
We've got something now that can do it in two minutes.
That's amazing.
But that came out of the COVID research, right?
So it's not going to be one single thing,
but it's me imagining a world of future
where we're going to be able to do sort of lower cost or very low cost.
Like your human genome was, I don't know, a billion dollars to first decode.
Now it's $300 where we're going to scale these things up to be able to do deep genomic analysis on individuals at scale.
And from those learnings, see the patterns in the data, see what sort of signal from noise and be able to then develop diagnostics and
therapeutics that help to kind of restore the body to optimal function and reverse that continuum
from disease backwards towards wellness that's kind of what the promises of this that is the
promise yeah but i think the important thing is it's got to be everything you do diagnostically has got to be on a clinically relevant time scale so with
genomics you know if you do deep genome sequencing i know it's got cheaper now but it's not it can't
be done on a the same day no and if you think about the way that most doctors work then they
need then they send something down to the path lab and it comes back you know soon and they say
crap means this and whatever it is.
You need to have something where there's a turnover of just a few hours in order
to make it clinically relevant for actionability.
There's no point in being able to diagnose something six months later.
And so we're very committed to the translational technology that gives you
rapid data because that's really impactful.
Yeah, and I feel like we're just at the beginning of this frontier
where first is understanding the biology
and then is figuring out how to apply novel therapeutics,
which aren't going to be, I don't think, a single targeted pathway or mechanism,
but really understanding a systems approach,
you know, what Lacoste and Barbasi call a multimodal approach to multi-causal diseases,
right? Using multiple kinds of things, like you have to treat all the things that are going on,
not just one. So, I mean, I'm just so excited about this. I'm so excited about the work that you've done at your institute and the ability for us to learn from that, and particularly around
long COVID, I think it's one of learn from that and particularly around long COVID,
I think it's one of those things that's causing so much disability, so much disease, so much
suffering. It's a little scared me a bit when you said that everybody who's had COVID has some
biochemical signature that there's still dysfunction going on.
It's probably true of influenza and other diseases as well. It's just that we don't know it.
Yeah, it's quite amazing. Well, again, thank you so much, Dr. Nichols, for your work. We're going
to keep following it. I hope everybody learned something. I think this is a fairly high-level
discussion, but why I wanted to bring it to you all was because this is where medicine is going,
and this is what you're all going to be getting, hopefully, in the next five to 10 years,
more and more. And I think with the advent of machine learning and AI and technology and our
ability to do deep analytics and phenomic analysis, we're going to learn so much. And this is going to
be today what seems like the dark ages in medicine. And we're going to have the light shown upon us
to understand the deep biology of what we're actually now understanding is the true nature
of disease, which is a systems problem. It's a network problem. And we have to treat things that
way. So thanks so much for being here at the Institute for Functional Medicine.
