    now I will turn it over to dr. Williams
  • 00:01:50
    I appreciate the opportunity to give
  • 00:01:54
    this webinar today on a topic that's
  • 00:01:57
    obviously very interesting and very
  • 00:01:59
    important for the functional medicine
  • 00:02:02
    community and obviously the patient's
  • 00:02:03
    that they serve so as was mentioned this
  • 00:02:08
    is information that comes out of one of
  • 00:02:11
    the recent books this was published last
  • 00:02:12
    year
  • 00:02:13
    functional strategies for the management
  • 00:02:16
    of gastrointestinal disorders we're
  • 00:02:17
    going to cover not all of this obviously
  • 00:02:20
    but you can see on the right-hand side
  • 00:02:22
    the four main are the five main areas
  • 00:02:23
    that are covered within this book from a
  • 00:02:27
    functional standpoint digestion or
  • 00:02:28
    absorption the microbial ecosystem of
  • 00:02:31
    the gut neural endocrine functions
  • 00:02:33
    elimination and detoxification and of
  • 00:02:36
    course the protective barrier or
  • 00:02:37
    interface is what we're going to kind of
  • 00:02:39
    cover today obviously in the 45 minutes
  • 00:02:42
    or so we have I'm not going to cover
  • 00:02:44
    every detail but I want to give a
  • 00:02:46
    highlight of kind of what we know about
  • 00:02:49
    where we can influence the barrier
  • 00:02:52
    function of the gut we can test for that
  • 00:02:55
    and then the very limited information
  • 00:02:57
    that we have about things that we know
  • 00:02:59
    function in in changing the the barrier
  • 00:03:04
    function of the gut in ways we can
  • 00:03:06
    measure so the idea of a barrier or
  • 00:03:09
    interface is really a you know universal
  • 00:03:12
    to all biology almost everything happens
  • 00:03:15
    at an interface whether it's the you
  • 00:03:18
    know the discrete different functions
  • 00:03:20
    between the inside and outside of a
  • 00:03:21
    tissue a cell and organelle a gene a
  • 00:03:24
    gene even has a beginning and an end we
  • 00:03:27
    know there's interfaces between the
  • 00:03:28
    promoter region coding region etc so
  • 00:03:30
    these interfaces are where we have all
  • 00:03:34
    of the organization all of the the
  • 00:03:39
    control of what happens in and outside
  • 00:03:42
    of that that system so and in order to
  • 00:03:44
    have a good interface we have to have a
  • 00:03:46
    barrier so if there is no barrier
  • 00:03:48
    between one side and the other the
  • 00:03:50
    interface obviously is of no use so if
  • 00:03:53
    you have a you know exquisite gate in a
  • 00:03:55
    wall that is supposed to control what
  • 00:03:58
    happens on each side of the wall
  • 00:04:00
    obviously it doesn't work if if the
  • 00:04:02
    barriers can completely destroyed so if
  • 00:04:06
    you go back to looking at these
  • 00:04:08
    interfaces or these places where we we
  • 00:04:12
    look at larger pieces of the way the bot
  • 00:04:14
    the body looks at surveilling risk or
  • 00:04:18
    risk from the environment you can see
  • 00:04:21
    these are three areas that I spend quite
  • 00:04:23
    a bit of time on the HPA axis and the
  • 00:04:25
    stress response the
  • 00:04:26
    UHN system and the GI system and if you
  • 00:04:29
    look at how they interface with one
  • 00:04:30
    their each one of these is a broad
  • 00:04:33
    interface that allows us to deal with in
  • 00:04:36
    the case of the HPA access stress from
  • 00:04:38
    outside the body and getting information
  • 00:04:41
    from the inside to get kind of give us
  • 00:04:43
    this idea of an overall stress response
  • 00:04:46
    the immune system is supposed to give us
  • 00:04:48
    this interface between self and non-self
  • 00:04:50
    and finally the GI tract is really this
  • 00:04:53
    large interface with the outside world
  • 00:04:55
    as we're going to see and it signals and
  • 00:04:58
    coordinates the immune system and the
  • 00:05:00
    brain and really all three of these are
  • 00:05:02
    related together and interestingly if
  • 00:05:05
    you look back at Hansell yays work on
  • 00:05:07
    the stress that he put in animals he
  • 00:05:10
    defined his stress response as an
  • 00:05:13
    alteration in the HPA access including
  • 00:05:16
    hypertrophy the adrenal gland atrophy of
  • 00:05:18
    the thymus so a change in the immune
  • 00:05:20
    system function and erosions in and or
  • 00:05:24
    ulcers and de la denhams a change in the
  • 00:05:26
    GI system so this was really the
  • 00:05:28
    coordinated definition he had he had and
  • 00:05:33
    he obviously looked at a number of
  • 00:05:34
    different things that said that this was
  • 00:05:36
    quintessential to a dysfunction in the
  • 00:05:40
    stress response or the surveillance
  • 00:05:43
    systems of the body so it's not
  • 00:05:44
    coincidental that these three are tied
  • 00:05:46
    together and it's one of the reasons why
  • 00:05:48
    I always see these three areas the HPA
  • 00:05:51
    axis the immune system in the GI system
  • 00:05:53
    is being highly coordinated in chronic
  • 00:05:56
    disease management and in many cases
  • 00:05:58
    acute disease management as well so as
  • 00:06:03
    we think of an interface especially when
  • 00:06:04
    it comes to the gut we want to think of
  • 00:06:07
    a couple different things here I wrote
  • 00:06:10
    this in I think in the beginning of the
  • 00:06:13
    book or on beginning of the barrier
  • 00:06:15
    chapter of the book that talks about not
  • 00:06:17
    imagining the barrier function is
  • 00:06:20
    meaning just something that keeps things
  • 00:06:22
    out but a sophisticated system to
  • 00:06:24
    communicate with and allow selective
  • 00:06:26
    entry of certain contents from the gut
  • 00:06:28
    lumen into the body requiring a tight
  • 00:06:30
    control but a thin barrier of tissue and
  • 00:06:33
    secretions intentionally designed for
  • 00:06:36
    close proximity to the gut lumen one of
  • 00:06:38
    the things that we need to think about
  • 00:06:39
    here in
  • 00:06:40
    that if the gut wanted to be just a
  • 00:06:42
    barrier it would be a much better
  • 00:06:44
    barrier the reason that the barrier
  • 00:06:46
    function of the gut is so tenuous
  • 00:06:49
    sometimes is because it's designed we
  • 00:06:51
    have cloaks close proximity to the gut
  • 00:06:54
    lumen because it needs signals it needs
  • 00:06:57
    nutrients it needs access to that
  • 00:06:59
    environment which is a very which
  • 00:07:02
    creates vulnerability to those same
  • 00:07:03
    microbes toxins and immunological
  • 00:07:05
    reactive components so I think that's
  • 00:07:08
    really an important feature of this
  • 00:07:10
    concept we need we probably need to
  • 00:07:13
    eventually use the word interface even
  • 00:07:15
    more so than barrier so obviously the
  • 00:07:19
    gut is designed for that system and one
  • 00:07:22
    of the ways it does that is by greatly
  • 00:07:24
    expanding its surface area so we see not
  • 00:07:27
    only the the GI tract creating these
  • 00:07:31
    large villi but then we have these micro
  • 00:07:36
    villi that greatly expand the surface
  • 00:07:38
    area if you just take the cells
  • 00:07:40
    themselves people say you know it's
  • 00:07:42
    about the size of a tennis court or
  • 00:07:43
    doubles tennis court obviously that's a
  • 00:07:45
    huge area for which the immune system
  • 00:07:48
    has to spread out and and protect sort
  • 00:07:53
    of like a castle wall it has to be sort
  • 00:07:55
    of a way to protect the whole thing all
  • 00:07:56
    the time when we have a vulnerability in
  • 00:07:59
    the case of you know an extreme case
  • 00:08:01
    like celiac disease where we have hyper
  • 00:08:03
    inflammation we see villous atrophy we
  • 00:08:06
    see an atrophy of the surface area and
  • 00:08:08
    obviously that has negative connotations
  • 00:08:11
    and negative consequences but that
  • 00:08:13
    actually is an adaptive response to the
  • 00:08:15
    protective mechanism of the oven the
  • 00:08:19
    barrier function if you have a tennis
  • 00:08:21
    court and you can shrink that down you
  • 00:08:24
    know into half that size you have half
  • 00:08:27
    the barrier to protect against and so
  • 00:08:30
    again this creates a benefit for some of
  • 00:08:33
    the interface functions but of a greater
  • 00:08:35
    vulnerability as well so if we think of
  • 00:08:38
    the functional components of the gut
  • 00:08:40
    barrier we have human GI cells we're
  • 00:08:42
    going to talk about those typically we
  • 00:08:44
    think of those as the entero sites and
  • 00:08:45
    the colonist sites we think of that is
  • 00:08:48
    this quote single layer of cells that
  • 00:08:50
    protects us the gut lumen from
  • 00:08:54
    the inside of the body we have obviously
  • 00:08:56
    the whole human immune cells that line
  • 00:08:58
    the inside or penetrate the interface
  • 00:09:00
    itself so we have those cells that we
  • 00:09:03
    want to think of as part of the gut
  • 00:09:05
    barrier we have neural endocrine cells
  • 00:09:08
    and neurons with synapses nearby so they
  • 00:09:10
    actually help communicate the barrier
  • 00:09:13
    function to the brain and the brain to
  • 00:09:15
    the barrier function so we have some
  • 00:09:18
    interface with neural endocrine cells we
  • 00:09:21
    have secretions from many of those cells
  • 00:09:23
    so we have secretions like mucus
  • 00:09:25
    secretory IgA antimicrobial peptides
  • 00:09:28
    enzymes acid neurotransmitters these are
  • 00:09:31
    all secretions that become part of the
  • 00:09:33
    gut barrier itself and finally we have
  • 00:09:36
    non-human microbes in the lumen and
  • 00:09:39
    mucous lining and so we think of these
  • 00:09:41
    is obviously commensal or passel bias or
  • 00:09:43
    potentially pathogenic bacteria viruses
  • 00:09:46
    both free BET viruses and bacteria
  • 00:09:48
    phages that are in bacteria fungi
  • 00:09:50
    non-human eukaryotic organisms maybe
  • 00:09:53
    some of those will be determined to be
  • 00:09:56
    commensals so there as we will see we
  • 00:09:59
    don't have a lot of time to get into the
  • 00:10:01
    the microbiota component in today but
  • 00:10:04
    there is quite a quite a bit of
  • 00:10:06
    information on how they influence both
  • 00:10:10
    beneficially and potentially negatively
  • 00:10:12
    the gut barrier function so as you look
  • 00:10:17
    at this image and this actually is a
  • 00:10:19
    graphic from the book itself to show
  • 00:10:21
    sort of the basic features of on the
  • 00:10:24
    left-hand side the small intestinal gut
  • 00:10:27
    barrier and on the right hand side the
  • 00:10:29
    colon got there you can see some some
  • 00:10:32
    differences the small intestines are
  • 00:10:35
    notably more have a greater surface area
  • 00:10:38
    with much larger villi the design mostly
  • 00:10:42
    to bring in more nutrients so we have
  • 00:10:46
    both Crypt and villi in small intestine
  • 00:10:48
    where as you can see in the colon we
  • 00:10:51
    mostly have crypts but not really many
  • 00:10:53
    villi the other major difference between
  • 00:10:56
    the two is on the left hand side you'll
  • 00:10:58
    see a single layer of mucus which is
  • 00:11:00
    kind of fragmented which is sort of the
  • 00:11:02
    gray so it looks like bricks they're
  • 00:11:05
    fragmented mucus because we
  • 00:11:08
    we need to have more access to the cells
  • 00:11:11
    in the small intestine where in the
  • 00:11:14
    large intestine we have two layers of
  • 00:11:16
    mucous a inner layer of mucous which is
  • 00:11:18
    very viscous and very difficult for
  • 00:11:21
    bacteria to penetrate an outer mucous
  • 00:11:24
    layer which is less viscous which is a
  • 00:11:26
    little more easy to penetrate for
  • 00:11:28
    bacteria and then the gut lumen where
  • 00:11:30
    you have most of the bacteria in the
  • 00:11:34
    colon and there's a very definite
  • 00:11:37
    difference between these two the small
  • 00:11:39
    intestine is designed as an interface
  • 00:11:41
    that is very absorptive and needs a lot
  • 00:11:45
    of interaction with the immune system
  • 00:11:47
    and with nutrient absorption whereas the
  • 00:11:51
    colon there is some interaction
  • 00:11:53
    obviously with the immune system much
  • 00:11:55
    less absorption and it really acts
  • 00:11:57
    primarily or in some cases primarily as
  • 00:12:01
    a fermentation for the the ecosystem the
  • 00:12:05
    microbiome that's there so there's quite
  • 00:12:08
    a bit of a different function and
  • 00:12:09
    therefore you're not surprised to see a
  • 00:12:11
    different sort of feature of the barrier
  • 00:12:14
    itself so let's just talk about some of
  • 00:12:16
    the cells that make up the barrier stem
  • 00:12:19
    cells are very important they sit at the
  • 00:12:22
    at the Nexus of the crypt and they're
  • 00:12:26
    essentially there to produce almost
  • 00:12:28
    every other cell type here so so they
  • 00:12:30
    are dividing and as the cells are moving
  • 00:12:33
    up the villi they are not only dividing
  • 00:12:36
    they're differentiating they're
  • 00:12:37
    differentiating into goblet cells that
  • 00:12:39
    produce mucus or some of the internal
  • 00:12:41
    endocrine cells that produce some of the
  • 00:12:43
    hormones or the absorptive cells in the
  • 00:12:45
    case of the entero sites the ability you
  • 00:12:47
    know to produce enzymes and/or
  • 00:12:49
    transporters so you have these going up
  • 00:12:53
    the villi and every 24 to 36 hours
  • 00:12:56
    you're seeing these cells turn over they
  • 00:13:00
    move up into out of the crypt into the
  • 00:13:02
    villi and they're being shed every 36 to
  • 00:13:05
    48 hours and so this is a Cantus is why
  • 00:13:07
    the the entero sites and the gut needs
  • 00:13:11
    so much energy and they need so many
  • 00:13:13
    building blocks is because it's a
  • 00:13:15
    constant turnover constant turnover and
  • 00:13:17
    as you can imagine every time a cell is
  • 00:13:19
    formed there needs to be a new
  • 00:13:21
    of tight junctions formed and so that's
  • 00:13:23
    why tight junction proteins become so
  • 00:13:25
    important as you as you is you're
  • 00:13:29
    producing these cells you have to
  • 00:13:30
    obviously produce the cells and their
  • 00:13:32
    connectivity to the other cells now this
  • 00:13:34
    is just showing this in two dimension
  • 00:13:36
    obviously it's in three dimensions so
  • 00:13:38
    it's actually going really always you
  • 00:13:40
    know towards you and away from you at
  • 00:13:42
    the same time the other cell type that
  • 00:13:44
    we have here is the Panem cell which are
  • 00:13:46
    shown on the right-hand side in green
  • 00:13:48
    and in the left hand side in yellow and
  • 00:13:50
    these actually go into the Crypt and
  • 00:13:53
    they produce quite a few of the
  • 00:13:56
    antimicrobial components that that are
  • 00:13:59
    there in the crypts because the Crypt is
  • 00:14:01
    a very protected space as it turns out
  • 00:14:04
    the Paneth cells I'll mention here in a
  • 00:14:07
    minute are also important for
  • 00:14:09
    maintaining stem cell function itself so
  • 00:14:12
    we have really from these stem cells we
  • 00:14:16
    make all of these different sort of
  • 00:14:18
    specialized cells so we know quite a bit
  • 00:14:21
    about the absorptive epithelial cells
  • 00:14:23
    I'm not going to spend a lot of time
  • 00:14:24
    talking about the details I'm going to
  • 00:14:27
    mention a few things about them but
  • 00:14:28
    they're located obviously primarily in
  • 00:14:31
    the duodenum and the ileum and jejunum
  • 00:14:36
    and we have a lot of these the ability
  • 00:14:38
    to move a lot of nutrients through the
  • 00:14:41
    transcellular route in a controlled
  • 00:14:44
    fashion to protect these cells obviously
  • 00:14:49
    the tight junctions become important so
  • 00:14:51
    I'm going to spend a little bit of time
  • 00:14:52
    explaining the tight junctions for those
  • 00:14:55
    of you who aren't as familiar with the
  • 00:14:57
    the proteins that are involved on the
  • 00:14:59
    left-hand side you can see this this
  • 00:15:02
    picture that gives you a better
  • 00:15:04
    understanding of what the tight
  • 00:15:06
    junctions are therefore they don't
  • 00:15:08
    actually close off the cell to cell
  • 00:15:10
    junction completely they actually end up
  • 00:15:12
    creating these very small pores which
  • 00:15:15
    allow water and a few small electrolytes
  • 00:15:18
    to get through and they're not just a
  • 00:15:20
    single connection you can see there it's
  • 00:15:23
    almost like a series of Ziploc if you
  • 00:15:26
    can imagine a series of Ziploc closures
  • 00:15:29
    with tiny little holes to allow water
  • 00:15:32
    and electrolytes through that's what
  • 00:15:33
    it's supposed to create
  • 00:15:35
    and it's usually up on the surface the
  • 00:15:39
    luminal surface you'll see most of the
  • 00:15:40
    tight junctions on the right-hand side
  • 00:15:42
    you can see that it's basically created
  • 00:15:45
    by these proteins that act as little
  • 00:15:48
    almost like velcro on one side you have
  • 00:15:50
    the clawed ins and including on the
  • 00:15:52
    other side you have other clods and
  • 00:15:53
    inclusions and other proteins that are
  • 00:15:56
    connected and they essentially can can
  • 00:15:59
    overlap one another and create this this
  • 00:16:01
    dynamic Junction and they're connected
  • 00:16:07
    on the inside to what we call 0 1 you
  • 00:16:10
    can see zone Yola occlude ins these are
  • 00:16:12
    these are types of proteins that connect
  • 00:16:15
    these these claudin and occlusions
  • 00:16:18
    together and they are in turn connected
  • 00:16:21
    to myosin and actin fibers and so what
  • 00:16:26
    happens is they are all sitting is if
  • 00:16:29
    you can imagine sitting together like a
  • 00:16:31
    like a Velcro connected to let's say
  • 00:16:34
    wires or rubber bands that if those are
  • 00:16:38
    pulled back then you can get an opening
  • 00:16:41
    of the tight Junction so instead of
  • 00:16:42
    having small aqueous pores you end up
  • 00:16:44
    having much larger pores and one of the
  • 00:16:47
    ways that that happens is a kinase
  • 00:16:49
    reaction or phosphorylation reaction
  • 00:16:51
    that's driven by something called myosin
  • 00:16:53
    light-chain kinase and ml c KS it's
  • 00:16:56
    referred to here and when that kind of
  • 00:16:59
    when that activity phosphorylates the
  • 00:17:01
    myosin chain it it contracts and pulls
  • 00:17:04
    back and opens up these these junctions
  • 00:17:08
    and that can that one of the main ways
  • 00:17:10
    that happens is inflammation
  • 00:17:12
    there's several inflammatory cascades
  • 00:17:14
    which will cause these to open up and
  • 00:17:17
    we're going to talk a little bit about
  • 00:17:18
    later about how we see that with lasagne
  • 00:17:23
    'ln and maybe ask the question about why
  • 00:17:26
    why does the do these cells have the
  • 00:17:28
    ability to do this if this was never
  • 00:17:30
    intended to be opened up why is there a
  • 00:17:32
    mechanism by which kinase can in this
  • 00:17:35
    case inflammation actually open this up
  • 00:17:37
    what seems like intentionally and most
  • 00:17:39
    people believe it's to give the immune
  • 00:17:42
    system more direct access to the lumen
  • 00:17:43
    unfortunately the reverse also is true
  • 00:17:46
    the lumen has more access to the immunes
  • 00:17:49
    so digestion of an absorption occurs
  • 00:17:52
    mostly in in the upper GI and we have
  • 00:17:56
    very specific places where absorption of
  • 00:17:59
    certain nutrients occurs one of the
  • 00:18:02
    things that's very important is that to
  • 00:18:05
    understand that it's a little bit
  • 00:18:06
    difficult to seem perhaps in a slide but
  • 00:18:08
    disaccharide ace is the enzymes that
  • 00:18:11
    break down maltose into its glucose
  • 00:18:14
    components or lactose into its
  • 00:18:16
    monosaccharides are located on the brush
  • 00:18:19
    border they're actually located not in
  • 00:18:21
    the lumen but they're actually located
  • 00:18:23
    on the cell surface and that occurs when
  • 00:18:27
    you have healthy and taro sites however
  • 00:18:29
    if you have an inflamed individual and
  • 00:18:33
    they they have villous atrophy and they
  • 00:18:35
    lose the number of cells that they would
  • 00:18:37
    have otherwise otherwise be there you
  • 00:18:40
    actually reduce the capacity then to
  • 00:18:43
    digest disaccharides you don't lose it
  • 00:18:46
    completely but you reduce that capacity
  • 00:18:49
    so you oftentimes will see people who
  • 00:18:51
    become lactose intolerant or intolerant
  • 00:18:54
    to other disaccharides as a secondary
  • 00:18:57
    effect to other inflammatory GI
  • 00:19:01
    conditions because you've lost some of
  • 00:19:03
    the benefit of the capacity of these
  • 00:19:05
    disaccharide aces you also as you can
  • 00:19:08
    see in the lower picture there you have
  • 00:19:10
    a number of enzymes that that take small
  • 00:19:14
    polypeptides and break them down into
  • 00:19:16
    amino acids and so and you have a number
  • 00:19:19
    of transporters as well so you'll also
  • 00:19:21
    perhaps have the inability to break down
  • 00:19:24
    certain small peptides and also then
  • 00:19:27
    drive potentially other immunological
  • 00:19:29
    reactions that will be secondary to
  • 00:19:32
    inflammatory conditions so it's really
  • 00:19:34
    important to understand that the entero
  • 00:19:36
    sites are not just there to absorb
  • 00:19:38
    nutrients sort of passively
  • 00:19:40
    that the transporters and the enzymes
  • 00:19:43
    that are involved are highly important
  • 00:19:45
    for especially in this case macro
  • 00:19:47
    nutrient absorption lipids are a little
  • 00:19:49
    different so they don't require enzymes
  • 00:19:51
    per se from from entero sites but
  • 00:19:54
    certainly disaccharides and small
  • 00:19:56
    polypeptides and so this becomes a very
  • 00:19:59
    important component
  • 00:20:01
    so again let's run through a few of
  • 00:20:04
    these others Paneth cells you know again
  • 00:20:07
    found only in the small intestines found
  • 00:20:10
    primarily in the ileum they migrate into
  • 00:20:12
    the Crypt after differentiation from
  • 00:20:14
    stem cells so they move down rather than
  • 00:20:16
    up and they are the primary secrete errs
  • 00:20:19
    of antimicrobial peptides in the gut
  • 00:20:21
    movement and so there's a different sort
  • 00:20:24
    of cells they're actually a few other
  • 00:20:25
    cells and parasites themselves actually
  • 00:20:27
    can produce some antimicrobial peptides
  • 00:20:29
    but in this case the pan of cells are
  • 00:20:32
    there they're very long-lived so they
  • 00:20:34
    don't turn over nearly as fast as those
  • 00:20:37
    that are migrating upward and then they
  • 00:20:40
    specifically help regulate the stem cell
  • 00:20:42
    activity so they're highly regulatory
  • 00:20:45
    and that's why it's important that they
  • 00:20:47
    function in the crypt in our you know so
  • 00:20:50
    vulnerable to other other stressors in
  • 00:20:54
    the GI lumen the immune system is
  • 00:20:57
    tightly bound to the GI to the GI cells
  • 00:21:02
    on the left hand side you can see
  • 00:21:03
    generally where you have these peyer's
  • 00:21:05
    patches and I've shown also that you
  • 00:21:08
    have epithelial cells these
  • 00:21:11
    intraepithelial lymphocytes on both
  • 00:21:13
    sides they're in blue and essentially
  • 00:21:15
    they tuck themselves in about every 10
  • 00:21:19
    to 15 cells they are there and so you
  • 00:21:23
    see about you see them interspersed all
  • 00:21:25
    throughout and essentially these are
  • 00:21:27
    very unique kinds of T cells and they
  • 00:21:32
    slightly different because they're more
  • 00:21:34
    regulatory type T cells rather than
  • 00:21:36
    affect their type T cells and they're
  • 00:21:38
    there to continually sense what's going
  • 00:21:40
    on dendritic cells are able to put their
  • 00:21:43
    arm all the way through into the gut
  • 00:21:46
    lumen and begin sampling what's going on
  • 00:21:48
    dendritic cells are really the
  • 00:21:49
    organizers of the immune system within
  • 00:21:52
    the gut and then on the left hand side
  • 00:21:54
    of the of the right picture where you
  • 00:21:57
    see these M cells M cells are called
  • 00:21:59
    micro fold cells these are special kinds
  • 00:22:02
    of Antero sites designed specifically to
  • 00:22:05
    allow antigens to come across and be
  • 00:22:08
    available in a controlled environment to
  • 00:22:11
    both dendritic cells and mostly T cells
  • 00:22:15
    so we have T and B cells and dendritic
  • 00:22:17
    cells who are that are all sitting there
  • 00:22:19
    sampling constantly sampling what is
  • 00:22:22
    available to it in the gut lumen this is
  • 00:22:25
    mostly occurring in the small intestines
  • 00:22:27
    where you have much more accessibility
  • 00:22:29
    to the M cells you have very little of
  • 00:22:33
    this going on in the colon so again the
  • 00:22:39
    colon is designed to be let's say more
  • 00:22:42
    of a barrier than the interface
  • 00:22:44
    functions of the small intestine so
  • 00:22:46
    there's two layers of mucus as we
  • 00:22:47
    mentioned there's an increased number of
  • 00:22:49
    goblet cells because they're the ones
  • 00:22:51
    producing mucin there's like I said less
  • 00:22:54
    interface more barrier much purer or a
  • 00:22:57
    much lower concentration of immune cells
  • 00:22:59
    we have what we call colon patches
  • 00:23:01
    rather than peyer's patches they're much
  • 00:23:04
    fewer and and much less concentrated in
  • 00:23:07
    their ability to function but obviously
  • 00:23:09
    they're they're there because you do
  • 00:23:11
    have breaches in the colon as well
  • 00:23:13
    there's fewer enter endocrine cells so
  • 00:23:16
    there's less cells that are signaling
  • 00:23:18
    because there's just less of that going
  • 00:23:21
    on here because you have really more of
  • 00:23:23
    a large capacity for fermentation so you
  • 00:23:27
    have really a controlled fermenting
  • 00:23:29
    environment rather than a in a
  • 00:23:32
    controlled interface environment and one
  • 00:23:37
    of the ways that that's controlled and I
  • 00:23:40
    talked quite a bit about this in the
  • 00:23:41
    book in our microbiota or microbiome
  • 00:23:44
    chapter is the idea that especially in
  • 00:23:47
    in the colon you have these different
  • 00:23:49
    layers the lumen which is which is has a
  • 00:23:53
    large amount of bacteria and you have
  • 00:23:58
    some that are that penetrate into the
  • 00:24:00
    outer mucous layer and very few these
  • 00:24:02
    are usually flagellated bacteria or
  • 00:24:05
    those that have very special
  • 00:24:06
    characteristics that are able to get all
  • 00:24:08
    the way down into the inner mucous layer
  • 00:24:10
    of the colon and this is controlled by a
  • 00:24:12
    number of different factors I speak
  • 00:24:15
    about in the book quite a bit about the
  • 00:24:16
    different mutants that make up both a
  • 00:24:19
    firm and the loose mucus in the in the
  • 00:24:24
    gut there are certain bacteria that
  • 00:24:26
    actually are intended or embed
  • 00:24:29
    themselves into the mucus Aquaman Jie
  • 00:24:32
    mucin Ophelia is one classic example
  • 00:24:34
    where we have a good commensal organism
  • 00:24:36
    that embeds itself in the mucus there's
  • 00:24:39
    different shear gradients so obviously
  • 00:24:42
    as the contents of the gut lumen are
  • 00:24:45
    moving of different shear forces which
  • 00:24:47
    affect which bacteria can survive
  • 00:24:49
    different oxygen gradients also affect
  • 00:24:53
    the ability for different bacteria to
  • 00:24:55
    survive in different areas of the gut
  • 00:24:57
    the availability of host defense
  • 00:25:00
    molecules the concentration of those the
  • 00:25:03
    ability for the immune system to produce
  • 00:25:04
    specific secretory IgA etc etc and as we
  • 00:25:10
    mentioned the change in nutrient in
  • 00:25:12
    within the mucus with what akka mancilla
  • 00:25:15
    and then the the cripton niche which is
  • 00:25:17
    extremely extremely special and needs to
  • 00:25:21
    be protected and so like it's shown here
  • 00:25:23
    only a few bacteria ever make it down
  • 00:25:25
    into that and there's a lot of data on
  • 00:25:29
    you know looking at you have to
  • 00:25:31
    obviously do this by biopsy to look at
  • 00:25:34
    different areas not only longitudinally
  • 00:25:36
    along the gut but then you know
  • 00:25:39
    sequentially or cross-sectionally across
  • 00:25:41
    the gut you have different microbiota
  • 00:25:44
    and all these different areas and all of
  • 00:25:47
    those are influencing the gut barrier
  • 00:25:49
    itself so breaking the gut barrier and
  • 00:25:54
    so the term leaky gut isn't as many of
  • 00:25:56
    you know is becoming I guess in some
  • 00:25:58
    ways more popular I showed on the right
  • 00:26:00
    hand side I did this briefly looked at
  • 00:26:04
    leaky gut on PubMed over the last well
  • 00:26:07
    since 1984 and you can see while it has
  • 00:26:10
    grown quite a bit in the last four or
  • 00:26:12
    five years we still don't have that many
  • 00:26:14
    hits per year I mean that the highest we
  • 00:26:17
    have is 26 hits in the last three years
  • 00:26:20
    and you know it really in night in 2010
  • 00:26:24
    2011 it just exceeded 10 so this term is
  • 00:26:28
    still not used that often and I pulled
  • 00:26:31
    this from WebMD I thought it was kind of
  • 00:26:33
    interesting
  • 00:26:34
    it says here from an MD standpoint it's
  • 00:26:36
    a very gray area says gee I guess our
  • 00:26:39
    neurologist
  • 00:26:40
    Donald Kirby
  • 00:26:42
    physicians don't know enough about the
  • 00:26:44
    gut which is our biggest immune system
  • 00:26:45
    Oregon leaky gut syndrome isn't a
  • 00:26:47
    diagnosis taught in medical school
  • 00:26:49
    instead
  • 00:26:50
    leaky gut really means you've got a
  • 00:26:52
    diagnosis that still needs be made you
  • 00:26:54
    hope that your doctor is good and enough
  • 00:26:56
    Sherlock Holmes but sometimes it's very
  • 00:26:58
    hard to make a diagnosis we don't know a
  • 00:27:00
    lot but we know that it exists says
  • 00:27:03
    Linda Lee from Johns Hopkins in the
  • 00:27:06
    absence of evidence we don't know what
  • 00:27:07
    it means or what therapies can directly
  • 00:27:09
    address it so as you know if you get a
  • 00:27:12
    hold of a book you realize I do like the
  • 00:27:15
    term intestinal permeability a little
  • 00:27:17
    more because and maybe other specific
  • 00:27:21
    terms but certainly leaky gut is is a
  • 00:27:23
    term that has unlike other terms maybe
  • 00:27:27
    is growing a little bit and people are a
  • 00:27:29
    little more comfortable with it as as we
  • 00:27:31
    know more about it here's a couple
  • 00:27:34
    papers just came out in last couple
  • 00:27:35
    years to kind of give you an idea leaky
  • 00:27:37
    gut is a danger signal for autoimmune
  • 00:27:39
    disease and on the right hand side
  • 00:27:41
    elevated fecal calprotectin in patients
  • 00:27:44
    with Alzheimer's dementia indicates
  • 00:27:45
    leaky gut so we're starting to see you
  • 00:27:48
    know other people use this in different
  • 00:27:49
    terms so it's a term that still is some
  • 00:27:53
    controversy behind it anyway one of the
  • 00:27:56
    reasons is is is because some people
  • 00:27:58
    view leaky gut as only this extreme view
  • 00:28:02
    and essentially what we mean by that
  • 00:28:04
    extreme view is a viewer basically you
  • 00:28:06
    know whole organisms are getting in past
  • 00:28:09
    the gut because there's the complete
  • 00:28:11
    breach of the barrier and we measure
  • 00:28:13
    this by you know septic sepsis or
  • 00:28:16
    systemic infections or you know little
  • 00:28:21
    polysaccharides or some you know
  • 00:28:22
    endotoxin iya kind of thing rather than
  • 00:28:25
    perhaps a more subtle of you that we're
  • 00:28:28
    seeing where we're just seeing small
  • 00:28:31
    immuno genic agents getting through or
  • 00:28:33
    alterations in the immune function
  • 00:28:35
    caused by changes in tight Junction
  • 00:28:38
    function so we know that there's various
  • 00:28:42
    ranges of what leaky gut can mean if you
  • 00:28:45
    look at a more common scenario here
  • 00:28:47
    where I'm showing some sort of
  • 00:28:50
    inflammation you can see at the top this
  • 00:28:52
    MLC is the is the myosin light-chain
  • 00:28:56
    that is phosphorylating the myosin
  • 00:28:58
    light-chain which is then pulling back
  • 00:29:00
    our occlusions and claude ins and
  • 00:29:02
    pulling back and opening up you can see
  • 00:29:06
    you can open up this the tight Junction
  • 00:29:09
    creating this intestinal permeability
  • 00:29:10
    and there's many different things that
  • 00:29:13
    can do that and of course gliadin or
  • 00:29:16
    gluten is sort of become the one of the
  • 00:29:19
    quintessential ways to look at this from
  • 00:29:21
    Sonia Lin and we'll look at that briefly
  • 00:29:24
    here so as many of you know
  • 00:29:28
    Eliseo pizanno did a number of you know
  • 00:29:33
    whole range of research in this area
  • 00:29:36
    looking specifically for cholera a
  • 00:29:40
    cholera toxin molecule actually and came
  • 00:29:45
    across a molecule that he end up coining
  • 00:29:49
    is on Ewan we also know that it's it
  • 00:29:52
    actually as part of another molecule but
  • 00:29:54
    Sanyal and became the name that he gave
  • 00:29:57
    to it and it he was he expanded this
  • 00:30:00
    story looking at the role of Zhan Ewan
  • 00:30:03
    and gland gluten or gladden as a trigger
  • 00:30:06
    for the whole leaky gut or intestinal
  • 00:30:10
    permeability component for those who
  • 00:30:12
    aren't as familiar with the story
  • 00:30:14
    essentially and we don't have time to
  • 00:30:16
    get into this in in detail today but
  • 00:30:19
    essentially what happens in it basically
  • 00:30:21
    from this picture from left to right up
  • 00:30:23
    at the top it's showing gluten or
  • 00:30:25
    gliadin a protein or peptide binding to
  • 00:30:29
    a protein on the cell surface the CXC
  • 00:30:33
    are three receptor and that triggers in
  • 00:30:36
    those cells or in some of those cells
  • 00:30:38
    depending on their genetics a high
  • 00:30:40
    amount of azan Ewan as on Yulin is again
  • 00:30:43
    this protein still a question about why
  • 00:30:45
    we produce this protein it's called pre
  • 00:30:48
    haptic labelling so maybe it has another
  • 00:30:50
    function in in the body but as on Yulin
  • 00:30:53
    is produced and secreted it can bind to
  • 00:30:56
    the cell surface of enterocyte and as it
  • 00:31:00
    binds to the cell surface it then
  • 00:31:03
    triggers myosin light-chain kinase which
  • 00:31:06
    then pulls back the the tight junctions
  • 00:31:10
    pulls back as I meal including one which
  • 00:31:12
    then pulls on occluding and Clawdeen's
  • 00:31:15
    and opens up this this disjunction and
  • 00:31:20
    you can see here obviously this allows
  • 00:31:23
    peptides in this case it's showing
  • 00:31:24
    gluten or gliadin peptides coming in and
  • 00:31:27
    binding to the T cells and creating in
  • 00:31:29
    certain individuals the the whole celiac
  • 00:31:32
    phenomenon and perhaps and other people
  • 00:31:34
    non celiac in you know gluten
  • 00:31:38
    sensitivity and all of that going on is
  • 00:31:41
    the question is why does the body have a
  • 00:31:43
    system why are these cells have a system
  • 00:31:45
    that allows the tight Junction to open
  • 00:31:48
    up and so many people are speculating
  • 00:31:49
    that in certain instances the body
  • 00:31:52
    actually creates a triggering signal
  • 00:31:54
    perhaps from certain peptides or
  • 00:31:56
    bacteria that triggers the opening of
  • 00:32:00
    the tight Junction intending for the
  • 00:32:02
    immune system to have greater access to
  • 00:32:04
    the gut moment in order to protect
  • 00:32:07
    itself however perhaps in an
  • 00:32:10
    overabundance of certain peptides like
  • 00:32:13
    gluten that this backfires and we end up
  • 00:32:16
    having too much activity too much immune
  • 00:32:19
    interaction with the gut lumen creating
  • 00:32:21
    the autoimmune cascade that we see with
  • 00:32:24
    with celiac but also other related
  • 00:32:27
    autoimmune diseases that may be
  • 00:32:29
    triggered so how do we measure this how
  • 00:32:32
    do we measure the permeability so
  • 00:32:35
    there's a number of different ways to do
  • 00:32:37
    this the gold standard is actually to do
  • 00:32:39
    an ex vivo biopsy of the gut cells and
  • 00:32:45
    you place them in what's called an icing
  • 00:32:47
    chamber and this picture on the
  • 00:32:48
    left-hand side essentially shows it only
  • 00:32:51
    shows one single cell but it would
  • 00:32:52
    imagine there's a series of cells all
  • 00:32:55
    oriented with the with the Lu little
  • 00:32:57
    side on one side so you have all of them
  • 00:33:00
    oriented the same way and now you can
  • 00:33:02
    measure their ability to allow in this
  • 00:33:06
    case it's showing chloride ions but you
  • 00:33:08
    can Ahmet Bey Salim Escher the trans
  • 00:33:10
    epithelial electrical resistance so you
  • 00:33:12
    can measure how easy can we get this
  • 00:33:16
    barrier to allow electrical resistance
  • 00:33:19
    and so if it if there's no resistance
  • 00:33:22
    obviously it means
  • 00:33:23
    that there's that we have a breach in
  • 00:33:27
    the barrier we have a very poor barrier
  • 00:33:29
    function and so this became sort of the
  • 00:33:31
    gold standard in not only can you do
  • 00:33:34
    this with biopsies you can actually just
  • 00:33:36
    grow cells along a nussing chamber and
  • 00:33:39
    then you can test you know botanical as
  • 00:33:42
    you can test other noxious agents and
  • 00:33:45
    see how they affect the gut barrier so a
  • 00:33:47
    lot of the data that that we know about
  • 00:33:50
    certain agents that either improve or
  • 00:33:54
    decreased gut barrier function occurs in
  • 00:33:57
    ex vivo icing chamber type reactions so
  • 00:34:01
    it's something that that you want to
  • 00:34:02
    keep in mind when you look at the
  • 00:34:04
    research we have less in vivo ways to do
  • 00:34:07
    this so one in vivo measure that is I
  • 00:34:09
    think generally thought of as as the
  • 00:34:11
    best currently is the size exclusion
  • 00:34:14
    test which is the typically thought of
  • 00:34:17
    as the lactulose mannitol test it's
  • 00:34:19
    probably the most common and essentially
  • 00:34:21
    this allows you to put different size
  • 00:34:24
    carbohydrates in this in the system
  • 00:34:26
    lactulose and mannitol
  • 00:34:28
    whereas mannitol should be able to get
  • 00:34:30
    through the cell surface through the
  • 00:34:33
    normal trans epithelial pathway gives
  • 00:34:38
    you sort of a big picture of what is the
  • 00:34:41
    denominator what is the gut area and
  • 00:34:43
    lactulose should not be able to get
  • 00:34:46
    easily across unless it's going through
  • 00:34:48
    between the cells so if you have
  • 00:34:50
    lactulose in your urine or a high level
  • 00:34:53
    of lactose it means you're getting more
  • 00:34:55
    and more of that through between the
  • 00:34:58
    cells so this lecture list of mannitol
  • 00:35:00
    tests becomes a general ratio that
  • 00:35:04
    allows you to give an idea of you know
  • 00:35:06
    what is the ratio between sort of the
  • 00:35:08
    overall surface of the gut and the
  • 00:35:10
    ability for lactose to get through a
  • 00:35:11
    pair of cellular manner there's a few
  • 00:35:13
    others that are used as well but the
  • 00:35:16
    lactose mannitol is probably the most
  • 00:35:17
    common so other tests that are available
  • 00:35:22
    or thought to have an effect I've got
  • 00:35:24
    permeability urine or serum levels for
  • 00:35:27
    microbial metabolites endotoxin d
  • 00:35:30
    lactate are often can be used increased
  • 00:35:34
    levels of bacteria and the dense mucus
  • 00:35:36
    that you actually can biopsy
  • 00:35:37
    the dense mucus and show that the more
  • 00:35:40
    bacteria in the dense mucus of the colon
  • 00:35:43
    the more likely you are to have a
  • 00:35:46
    intestinal permeability reduced plasma
  • 00:35:49
    citrulline as a biomarker of glutamine
  • 00:35:52
    fecal calprotectin as we've seen has
  • 00:35:54
    also been shown to be connected with
  • 00:35:56
    that it's mostly obviously an
  • 00:35:57
    inflammatory marker but very linked to
  • 00:36:01
    to get permeability and you can also
  • 00:36:05
    measure Sanyal in claudin occluding and
  • 00:36:08
    to look at tight Junction proteins these
  • 00:36:10
    are often done ex vivo but you can also
  • 00:36:12
    look at these and there's some data
  • 00:36:15
    suggesting that and then serum and maybe
  • 00:36:18
    fecal asan Yulin is also being used
  • 00:36:20
    quite readily
  • 00:36:21
    now as a marker of intestinal
  • 00:36:24
    permeability or
  • 00:36:25
    I should probably say a marker of gut
  • 00:36:28
    barrier function which is which may or
  • 00:36:30
    may not result always in intestinal
  • 00:36:33
    permeability per se so we know that
  • 00:36:35
    there are many conditions any condition
  • 00:36:36
    where you're putting stress on the gut
  • 00:36:39
    in an inflammatory stress we know less
  • 00:36:43
    about for instance things like IBS there
  • 00:36:46
    are some studies that show IBS with
  • 00:36:48
    diarrhea is statistically connected with
  • 00:36:51
    changes in gut barrier function although
  • 00:36:54
    in other cases it's not probably because
  • 00:36:57
    IBS definition is not always as clear in
  • 00:36:59
    different cohorts and then there's some
  • 00:37:03
    question about SIBO whether SIBO as a
  • 00:37:06
    diagnosis is connected with changes in
  • 00:37:10
    barrier function what we do know is
  • 00:37:12
    there's a growing amount of research
  • 00:37:13
    suggesting that obese subjects are have
  • 00:37:17
    more and more intestinal permeability
  • 00:37:20
    there's a number of different studies
  • 00:37:21
    now looking at this looking at in this
  • 00:37:24
    case serum Sanyal levels go up in in
  • 00:37:26
    most cases with obesity and insulin
  • 00:37:28
    resistance so something that that were
  • 00:37:30
    obviously is a growing problem and
  • 00:37:33
    should be looked at in those subjects
  • 00:37:36
    one of the issues we have in looking at
  • 00:37:39
    the data on preventing and treating is
  • 00:37:42
    that intestinal permeability is often
  • 00:37:44
    not measured like I said there's some of
  • 00:37:46
    these studies that look at uh Singh
  • 00:37:47
    chambers but very few human clinical
  • 00:37:49
    trials at
  • 00:37:51
    look at this so you started looking in
  • 00:37:53
    the literature and say will there data
  • 00:37:55
    on dietary interventions and changing
  • 00:37:57
    that permeability levels well there
  • 00:38:00
    actually are very few I actually found
  • 00:38:02
    this one that showed when they actually
  • 00:38:05
    gave now you may not like this but they
  • 00:38:08
    give pasta you know a wheat product but
  • 00:38:11
    they gave them a five-week crossover
  • 00:38:13
    study looking at healthy young
  • 00:38:15
    individuals giving them 800 grams of
  • 00:38:17
    pasta with and without inulin which is a
  • 00:38:19
    prebiotic that stimulates bacteria tip
  • 00:38:23
    typically and you can see they saw a
  • 00:38:25
    statistical change in just five weeks a
  • 00:38:29
    statistical reduction in lactulose
  • 00:38:31
    mannitol a reduction in serum Sanyal in
  • 00:38:33
    and a slight increase in glp-1 which is
  • 00:38:36
    which is an an endocrine component in
  • 00:38:40
    the gut so again very few I mean I wish
  • 00:38:43
    I had a hundred papers to show you but
  • 00:38:45
    there are very few like this kind of
  • 00:38:48
    study and this was just done just a few
  • 00:38:49
    years ago if you look in the data and
  • 00:38:51
    say how about micronutrients vitamins
  • 00:38:53
    minerals all the things that we we think
  • 00:38:54
    are good for the gut we have very very
  • 00:38:56
    limited data especially in what I call
  • 00:38:59
    healthy or relatively healthy Westerners
  • 00:39:01
    most of these are done in either very
  • 00:39:06
    sick children or in people that exercise
  • 00:39:10
    intensively and see a drop in gut
  • 00:39:12
    permeability or increase I should say
  • 00:39:15
    and gut permeability and a decrease in
  • 00:39:17
    immune function so one of those that we
  • 00:39:20
    often think about quite often is
  • 00:39:21
    glutamine which we're you know for as
  • 00:39:23
    many years as I've heard about glutamine
  • 00:39:25
    you'd think there'd be hundreds and
  • 00:39:26
    hundreds of studies on the role of
  • 00:39:28
    glutamine and barrier function and it
  • 00:39:29
    turns out very few most of these are on
  • 00:39:33
    burn or a severe injury patients it's
  • 00:39:37
    frequently used with you know I mean I
  • 00:39:39
    think probably many people that are
  • 00:39:41
    listening to this would say you know
  • 00:39:42
    they've gotten great results using
  • 00:39:44
    glutamine but the research on it is very
  • 00:39:47
    very limited when you look at animal
  • 00:39:50
    studies and cell culture studies there's
  • 00:39:52
    a whole list of things I'm not going to
  • 00:39:53
    go down this list you have the slide but
  • 00:39:55
    there are numerous explanations for why
  • 00:39:57
    we think glutamine would affect
  • 00:39:59
    intestinal barrier function it improves
  • 00:40:02
    almost everything we want to look at
  • 00:40:04
    this is a great recent review published
  • 00:40:07
    this year on the role of glutamine
  • 00:40:08
    intestines and its implications and
  • 00:40:10
    intestinal diseases I would recommend
  • 00:40:12
    that you get it but you can see you know
  • 00:40:14
    the standard sort of things that we
  • 00:40:16
    would think about all benefitting and
  • 00:40:18
    and and what we would assume maintaining
  • 00:40:21
    intestinal tissue integrity however like
  • 00:40:25
    I said we have very few studies in
  • 00:40:27
    humans this this study that I show you
  • 00:40:30
    here shows that they took these
  • 00:40:32
    Brazilian shantytown children that had
  • 00:40:34
    high levels of intestinal barrier or I
  • 00:40:37
    should say low levels of intestinal
  • 00:40:38
    barrier function and they will improve
  • 00:40:40
    thriving they were able to improve their
  • 00:40:43
    freighting but they actually didn't
  • 00:40:44
    really see much of a change and they
  • 00:40:47
    didn't really aim look at the the level
  • 00:40:51
    of intestinal permeability you can see
  • 00:40:53
    below here a meta-analysis on on
  • 00:40:55
    critically ill patients looking at
  • 00:40:58
    glutamine enriched enteral feeding so
  • 00:41:00
    these are studies that are not you know
  • 00:41:02
    the typical ones that you're seeing
  • 00:41:04
    here's a study where they actually
  • 00:41:05
    looked at patients with crohn's disease
  • 00:41:08
    and you can see they use both glutamine
  • 00:41:11
    and saw an improvement and in intestinal
  • 00:41:14
    permeability but look at the dose 40
  • 00:41:16
    grams of glutamine they gave them half a
  • 00:41:18
    gram for every kilogram of ideal body
  • 00:41:19
    weight so this is for an 80 kilogram
  • 00:41:22
    person at me for two grams of glutamine
  • 00:41:23
    so this is again an extreme sort of
  • 00:41:26
    situation a few others that we have in
  • 00:41:28
    the literature are during immune
  • 00:41:32
    function during heavy load training
  • 00:41:34
    given glutamine 10 grams a day you can
  • 00:41:36
    see that they were able to attenuate and
  • 00:41:38
    ten you ate the immuno suppression but
  • 00:41:41
    they didn't actually measure that
  • 00:41:42
    permeability so we can assume there was
  • 00:41:45
    some benefit but we don't know so I tend
  • 00:41:48
    to tell people that you know the dose
  • 00:41:51
    recommendation for a lot of clinicians
  • 00:41:52
    is somewhere in the four to eight grams
  • 00:41:54
    a day range which typically requires
  • 00:41:56
    this to be taken not in capsules but you
  • 00:41:58
    know in powders and again large
  • 00:42:02
    anecdotal data out data set out there
  • 00:42:04
    but very little clinical trials for me
  • 00:42:07
    to tell you exactly if you see you know
  • 00:42:10
    this intellectualist mannitol test and
  • 00:42:12
    you give this amount of glutamine you're
  • 00:42:14
    going to see this kind of change in this
  • 00:42:15
    amount of time we need more
  • 00:42:18
    and we and actually we need more people
  • 00:42:19
    publishing their data so that we can get
  • 00:42:22
    access to this information we know that
  • 00:42:25
    there's a lot of phytonutrients out
  • 00:42:27
    there that we I can't go through all of
  • 00:42:30
    them and I'm not going to try but
  • 00:42:32
    there's a number of them I typically
  • 00:42:34
    tell people phytonutrients should be
  • 00:42:38
    thought of as a way to diversify the
  • 00:42:41
    diet not that you're trying to get a
  • 00:42:43
    specific dose it's really better to
  • 00:42:45
    think of following a long-term low-dose
  • 00:42:49
    supplementation ie
  • 00:42:51
    good diversity in the in the fruits and
  • 00:42:54
    vegetables that you eat and or the
  • 00:42:56
    supplements that you can supplement with
  • 00:42:57
    the diversity of phytonutrients
  • 00:42:59
    berberine is one that's kind of come on
  • 00:43:01
    the scene which is interesting because
  • 00:43:02
    there's been some study and animal
  • 00:43:05
    suggesting that it can improve
  • 00:43:06
    intestinal barrier function and so we've
  • 00:43:10
    seen some of this data
  • 00:43:11
    improving tight junctions improving in
  • 00:43:15
    animal models both type 2 diabetic
  • 00:43:17
    animal models so we we see that effect
  • 00:43:19
    when it comes to humans as well here's a
  • 00:43:22
    study looking at IBS in humans looking
  • 00:43:26
    at changes in diarrhea given burring
  • 00:43:30
    burring hydrochloride you can see a
  • 00:43:32
    benefit on the left-hand side for the
  • 00:43:34
    change in urgent need for defecation
  • 00:43:35
    they gave this for eight weeks you can
  • 00:43:37
    see it continued down for eight weeks
  • 00:43:39
    and after they stopped it went back up
  • 00:43:40
    so whether or not this is related at all
  • 00:43:43
    to gut barrier function we don't know
  • 00:43:45
    because they didn't measure it and gut
  • 00:43:48
    permeability is not often measured in
  • 00:43:50
    some of these studies probiotics are
  • 00:43:53
    often thought to be beneficial again
  • 00:43:56
    they act good commensal organisms are
  • 00:43:58
    always acting to benefit the gut there's
  • 00:44:01
    a number of different studies that have
  • 00:44:02
    looked at in vitro these are in vitro
  • 00:44:04
    studies mostly looking at uh Seng
  • 00:44:07
    chamber type product of experiments and
  • 00:44:11
    you can see you know Bifidobacterium
  • 00:44:13
    bacteria lactobacillus plantarum bsl-3
  • 00:44:16
    which is a combination of eight
  • 00:44:18
    different bacteria bifida bacteria and
  • 00:44:20
    Santis and el acidophilus and at the
  • 00:44:22
    bottom you can see Saccharomyces
  • 00:44:24
    boulardii I believe that if you look
  • 00:44:26
    beyond these you'll see that most
  • 00:44:28
    lactobacilli at best little bacteria and
  • 00:44:30
    probably sacrum
  • 00:44:32
    anything that improves sort of the
  • 00:44:34
    status of the gut is likely to have some
  • 00:44:36
    sort of triggering effect on improving
  • 00:44:38
    the intestinal barrier function there
  • 00:44:40
    might be some exceptions to that but I
  • 00:44:41
    think that's mult going to be mostly
  • 00:44:43
    true a good gut microbiota is going to
  • 00:44:46
    improve gut barrier function we see a
  • 00:44:49
    few different studies this was actually
  • 00:44:51
    a meta-analysis looking at a number of
  • 00:44:53
    Chinese studies on patients going in
  • 00:44:57
    with colorectal cancer for operate a
  • 00:44:59
    firfer
  • 00:45:00
    for colorectal cancer operations and
  • 00:45:03
    they showed that they were able to
  • 00:45:05
    improve the lactulose to mannitol tests
  • 00:45:07
    with almost every probiotic strain and
  • 00:45:09
    dose they tried so again these are
  • 00:45:11
    somewhat low quality studies but kind of
  • 00:45:14
    gives you the idea that when you start
  • 00:45:16
    looking at this there seems to be some
  • 00:45:19
    improvement here was just one of the
  • 00:45:21
    studies looking at 160 subjects giving
  • 00:45:23
    probiotics and this was actually a
  • 00:45:25
    combination of plantarum acidophilus and
  • 00:45:28
    B long them and you can see that
  • 00:45:31
    post-operative serums on Yulin excuse me
  • 00:45:34
    if you look up in the upper left hand
  • 00:45:35
    corner you can see bacterial
  • 00:45:36
    translocation went down at the lower
  • 00:45:39
    left hand side you can see the the trans
  • 00:45:42
    epithelial resistance so this is a uh
  • 00:45:43
    Singh chambered study or test and you
  • 00:45:46
    can see that went up so it improved and
  • 00:45:48
    up in the right-hand corner you can see
  • 00:45:50
    lactulose and mannitol test went down
  • 00:45:53
    and the the transmitted coastal
  • 00:45:56
    permeation which means bacteria within
  • 00:45:59
    the the mucus went down so this was
  • 00:46:01
    again all the things that they measured
  • 00:46:03
    which you know wasn't
  • 00:46:04
    systemic but they all improved with
  • 00:46:07
    giving this blend of a probiotic here's
  • 00:46:11
    another study looking at probiotic
  • 00:46:14
    supplements we just think and contain
  • 00:46:16
    six different probiotics Bifidobacterium
  • 00:46:19
    lactobacillus etc and they looked at
  • 00:46:21
    fecal zaniel and levels in these
  • 00:46:23
    individuals and you can see fecal zhonya
  • 00:46:25
    limb levels to go down and again equals
  • 00:46:28
    on you and and maybe is not as
  • 00:46:30
    consistent as serums on you and as far
  • 00:46:32
    as predicting function of the gut but
  • 00:46:34
    nonetheless another study looking at
  • 00:46:36
    this Saccharomyces boulardii and this
  • 00:46:40
    set of Crohn's patients you can see a
  • 00:46:42
    very modest dose of sacrum I see blood
  • 00:46:45
    400 million CFU not even in the billions
  • 00:46:48
    given every eight hours of those so this
  • 00:46:50
    was given quite frequently and you can
  • 00:46:52
    see that given sacrifices Velarde these
  • 00:46:56
    Crohn's disease patients that we're
  • 00:46:58
    seeing they're lactose the mannitol
  • 00:47:00
    racial go up went down dramatically
  • 00:47:02
    after being given the sacrum Isis
  • 00:47:05
    Velarde so again these these studies are
  • 00:47:09
    very limited but they do suggest the
  • 00:47:12
    things that we've been talking about how
  • 00:47:14
    about colostrum is just just another
  • 00:47:16
    couple things colostrum has been shown
  • 00:47:18
    to look at this these are an athlete's
  • 00:47:20
    again and I if I can just give you one
  • 00:47:22
    from a lifestyle standpoint if you have
  • 00:47:24
    someone that has gut issues especially
  • 00:47:27
    if you think there's barrier issues and
  • 00:47:28
    immune related issues one of the ways
  • 00:47:31
    you can exacerbate that negatively is to
  • 00:47:33
    have them become you know these athletes
  • 00:47:36
    that strain and stress themselves so
  • 00:47:38
    these are again a classic way to improve
  • 00:47:41
    or to induce I should say intestinal
  • 00:47:44
    permeability and induce
  • 00:47:47
    immunosuppression is you know run a
  • 00:47:49
    marathon so they take a lot of these
  • 00:47:51
    individuals and they look at ways they
  • 00:47:53
    can improve that in this case colostrum
  • 00:47:55
    was able to improve the lactulose to
  • 00:47:57
    mannitol ratio and reduce people's on
  • 00:47:59
    Yulin levels when given 500 milligrams
  • 00:48:02
    up with 500 milligrams of bovine
  • 00:48:05
    colostrum per day so I know that I've
  • 00:48:10
    covered only a little bit of a lot of
  • 00:48:12
    things but I my job was to sort of give
  • 00:48:14
    this overview of barrier function and
  • 00:48:16
    what we can do about it so some of the
  • 00:48:18
    things you want to think about obviously
  • 00:48:19
    avoid foods that are going to create
  • 00:48:21
    intestinal permeability NSAIDs are a
  • 00:48:24
    real nono they're going to be a problem
  • 00:48:26
    so if you can all ask them to reduce or
  • 00:48:30
    eliminate their use of NSAIDs that's
  • 00:48:31
    going to help you dramatically reducing
  • 00:48:34
    stress we have time to talk about it but
  • 00:48:36
    stress obviously has a direct effect on
  • 00:48:38
    on the tight junctions avoiding
  • 00:48:42
    strenuous physical activity avoiding
  • 00:48:44
    processed foods with artificial colors
  • 00:48:46
    and flavors often these inflamed or
  • 00:48:48
    cause the same problems and eat abundant
  • 00:48:50
    amounts of fresh fruits and vegetables
  • 00:48:51
    maximize phytonutrient diversity and
  • 00:48:55
    then the list of things that I have here
  • 00:48:57
    are a little bit broader than what I'm
  • 00:48:58
    mention but you can see glutamine
  • 00:49:00
    vitamin D omega-3 fatty acids Pro and
  • 00:49:04
    prebiotics zinc can also be shown we see
  • 00:49:08
    we know that zinc deficiency can
  • 00:49:12
    increase intestinal permeability only
  • 00:49:14
    use iron if you've shown that they do
  • 00:49:16
    have iron deficiency don't just use that
  • 00:49:19
    prophylactically flavonoids colostrum
  • 00:49:22
    and then consider potentially berberine
  • 00:49:24
    especially of a you have a subject who
  • 00:49:26
    is insulin resistant and has type 2
  • 00:49:27
    diabetes where that would be beneficial
  • 00:49:29
    for other reasons so I went fairly
  • 00:49:34
    quickly and hopefully I've covered
  • 00:49:37
    enough that that we can get some
  • 00:49:40
    questions or at least follow-up later on
  • 00:49:42
    and that I'll hand it over to you now
  • 00:49:45
    Michael great thank you dr. Williams
  • 00:49:48
    just a terrific presentation we've
  • 00:49:50
    received a lot of feedback already and I
  • 00:49:53
    just want to remind everyone that the
  • 00:49:54
    PowerPoint will be available on our
  • 00:49:56
    website in PDF format next week we did
  • 00:49:59
    receive quite a few clinical questions
  • 00:50:00
    or general questions so let me just
  • 00:50:03
    start with there is a question around
  • 00:50:06
    research indicating that the potential
  • 00:50:08
    of overdosing or using a too much
  • 00:50:10
    supplementation with probiotics might
  • 00:50:13
    lead to increased immune load I didn't
  • 00:50:15
    know if you had any comment or if you
  • 00:50:17
    run across that so there are a lot of
  • 00:50:21
    clinicians that I think have been told
  • 00:50:23
    or just assumed that the use of
  • 00:50:25
    probiotics when you have some money that
  • 00:50:28
    let's say has high electives to mannitol
  • 00:50:30
    or suspicious of leaky gut that we
  • 00:50:33
    should avoid that because all of a
  • 00:50:34
    sudden we're going to create endotoxemia
  • 00:50:36
    or some other kind of thing I think
  • 00:50:38
    first of all there's no evidence of that
  • 00:50:39
    and two we would never imagine that
  • 00:50:42
    making the gut a septic is the solution
  • 00:50:45
    for a good barrier so as it turns out
  • 00:50:50
    from the data that we've seen and I
  • 00:50:52
    think just logically what we know about
  • 00:50:53
    good commensal organisms that the use of
  • 00:50:56
    probiotics is not contraindicated when
  • 00:50:59
    somebody has intestinal permeability or
  • 00:51:01
    leaky gut and in fact may actually be
  • 00:51:03
    beneficial so if you have if you believe
  • 00:51:07
    that your D getting endotoxemia because
  • 00:51:10
    you've got this major leaky gut you know
  • 00:51:12
    we're
  • 00:51:12
    not going to give antibiotics to wipe
  • 00:51:15
    out the gut so adding good bacteria is
  • 00:51:18
    certainly not going to be a problem it's
  • 00:51:19
    never been shown to be a problem and the
  • 00:51:21
    limited data we have suggested it's
  • 00:51:23
    actually beneficial great thank you
  • 00:51:26
    another question around whether you've
  • 00:51:28
    seen any research suggesting an impact
  • 00:51:31
    of Lyme STIs or other tick-borne
  • 00:51:33
    diseases on gut barrier function you
  • 00:51:39
    know I have never specifically looked at
  • 00:51:41
    that I would not at all be surprised if
  • 00:51:43
    there are some data suggesting that that
  • 00:51:45
    line lime or tick borne diseases are
  • 00:51:48
    really really any immune anything that
  • 00:51:51
    would affect the immune system that
  • 00:51:52
    dramatically would have gut barrier
  • 00:51:55
    changes but I have not specifically
  • 00:51:58
    looked at that or seen that report it
  • 00:52:00
    but it would not at all surprised me
  • 00:52:02
    another question about how long you know
  • 00:52:06
    kind of a timeline do you think that it
  • 00:52:08
    might take to to really restore repair
  • 00:52:10
    and inflamed GI tract and you know even
  • 00:52:13
    bring about better nutritional status
  • 00:52:16
    and and digestion absorption status so I
  • 00:52:20
    mean obviously that's very patient
  • 00:52:23
    specific if we if we step up back aways
  • 00:52:27
    and I don't want to make it seem like
  • 00:52:28
    the gut barrier is becomes everything we
  • 00:52:32
    if we back up and look at you obviously
  • 00:52:33
    the whole idea of what's going on in the
  • 00:52:36
    gut and you know the traditional sort of
  • 00:52:38
    for our approach and all these sort of
  • 00:52:40
    things it really depends if the first
  • 00:52:42
    are is to remove and you've got a
  • 00:52:45
    patient that is you know basically
  • 00:52:48
    sabotaging themselves with their own
  • 00:52:50
    diet routinely and they're exposed to
  • 00:52:54
    other things in their diet and alcohol
  • 00:52:56
    and other things and you're constantly
  • 00:52:57
    seeing a you know assault on on the gut
  • 00:53:00
    you know how long is it going to take
  • 00:53:02
    them to stop doing that so in one
  • 00:53:05
    subject you know you may be able to get
  • 00:53:08
    them to go cold turkey away from things
  • 00:53:10
    that are harming them others it may take
  • 00:53:11
    a long time so I think that's a that's a
  • 00:53:14
    huge part that I think people don't
  • 00:53:16
    realize you you know glutamine and you
  • 00:53:19
    know but phytochemicals and probiotics
  • 00:53:21
    in the midst of a diet that is
  • 00:53:24
    constantly assaulting the gut is is
  • 00:53:26
    take forever in fact it may never
  • 00:53:28
    benefit you so I think it really depends
  • 00:53:31
    I think if you have a very if you have a
  • 00:53:34
    compliant and a person that's willing to
  • 00:53:36
    change their diet very quickly I think
  • 00:53:39
    you can start seeing you know things
  • 00:53:40
    some people obviously within 3-4 days
  • 00:53:43
    you'll start seeing some dramatic
  • 00:53:44
    changes in some symptom ology if you've
  • 00:53:47
    got major breaches in the gut and you
  • 00:53:50
    know history of antibiotics and things
  • 00:53:52
    like that it may take a while to rebuild
  • 00:53:54
    but I would think you're going to see a
  • 00:53:56
    consistent increase month by month by
  • 00:53:58
    month and in some cases I think you
  • 00:54:01
    should if you're not seeing anything by
  • 00:54:02
    six months you probably are missing
  • 00:54:05
    something you might be missing a
  • 00:54:06
    parasite that you didn't recognize or
  • 00:54:08
    some other other thing going on and then
  • 00:54:10
    I think the issue is not the gut repair
  • 00:54:12
    process but really a diagnostic issue
  • 00:54:14
    what are you missing and so I think it's
  • 00:54:17
    going to be different for each
  • 00:54:18
    individual but it's not going to be
  • 00:54:20
    instantaneous
  • 00:54:21
    and these takes months in some cases
  • 00:54:23
    clinicians will tell you years to really
  • 00:54:25
    get to the point where the gut is not
  • 00:54:28
    vulnerable easily vulnerable to you know
  • 00:54:31
    just one you know off the wagon kind of
  • 00:54:33
    thing great um I found an interesting
  • 00:54:37
    you mentioned that the large intestine
  • 00:54:39
    really kind of acts as a fermenting
  • 00:54:40
    vessel and so what are some of the
  • 00:54:43
    changes that you might see or expect to
  • 00:54:46
    see in the development of small
  • 00:54:47
    intestinal bacterial overgrowth
  • 00:54:49
    and and kind of your thoughts around how
  • 00:54:52
    the etiology how that might develop and
  • 00:54:56
    so if you if you and this is a kind of a
  • 00:55:00
    tricky subject but if you look at small
  • 00:55:02
    intestinal bacterial overgrowth and what
  • 00:55:05
    we do to define it now again the gold
  • 00:55:07
    standard for that is actually you know
  • 00:55:09
    aspiration of the duodenum or the ileum
  • 00:55:11
    and actually counting bacteria and
  • 00:55:13
    getting a numbering saying that we
  • 00:55:15
    actually have an overgrowth in the small
  • 00:55:17
    intestine the other issue the other way
  • 00:55:19
    to look at that is a breath test and a
  • 00:55:22
    breath test is and if we don't time to
  • 00:55:23
    get into that a breath test positive can
  • 00:55:27
    be SIBO can be overgrowth of bacteria
  • 00:55:29
    but it can be anything that creates that
  • 00:55:32
    fermentation early which can be bowel
  • 00:55:34
    trying to time which can be even certain
  • 00:55:36
    bacteria in the small bowel whether
  • 00:55:38
    they're overgrown overall or not
  • 00:55:40
    so it gives us some idea that something
  • 00:55:42
    is going on and we have symptom ology
  • 00:55:44
    based on you know sort of this
  • 00:55:46
    fermentation process so the the small
  • 00:55:50
    intestine should not be a fermenting of
  • 00:55:53
    vessel typically and typically the
  • 00:55:57
    lactobacilli and the bit you know like a
  • 00:55:59
    basilica that are reside there and other
  • 00:56:00
    bacteria that reside there are there
  • 00:56:02
    typically doing other things and one of
  • 00:56:05
    the things that they're doing is they're
  • 00:56:07
    having much more interaction with the
  • 00:56:08
    immune system and so that's why even
  • 00:56:10
    small amounts of bacteria lack of a
  • 00:56:12
    silly we say well you know it seems like
  • 00:56:13
    a drop in the bucket compared to what's
  • 00:56:15
    in the colon but if they're in the small
  • 00:56:18
    intestine they don't need high doses we
  • 00:56:20
    don't need high amounts that are there
  • 00:56:22
    because they're doing other sorts of
  • 00:56:23
    things so we certainly about transit
  • 00:56:27
    time is slow if acid is low if other
  • 00:56:29
    things are going on you can get this
  • 00:56:31
    migration of bacteria from the colon
  • 00:56:34
    into the small intestine which creates
  • 00:56:35
    problems some of which we can measure
  • 00:56:38
    when we do either the glucose or lactose
  • 00:56:41
    test for the breath but may or may not
  • 00:56:45
    be SIBO in many of those cases great
  • 00:56:48
    yeah and I know that was a very large
  • 00:56:50
    topic probably its own webinar we had a
  • 00:56:52
    lot of questions around where a lot of
  • 00:56:55
    questions about the book so I just want
  • 00:56:56
    to give you an opportunity to inform the
  • 00:56:58
    audience about where they can get the
  • 00:57:00
    book and n speak to that so you know the
  • 00:57:04
    book is published to the point Institute
  • 00:57:06
    and you can you can purchase the book
  • 00:57:08
    through what's called a lifestyle matrix
  • 00:57:10
    resource center l MRC we call it a
  • 00:57:13
    lifestyle matrix resource center and so
  • 00:57:15
    it's if you look it up online lifestyle
  • 00:57:18
    matrix you can you can find it there and
  • 00:57:22
    you can purchase it directly
  • 00:57:25
    I don't know of Genova actually is if
  • 00:57:28
    you can create a link for that and let
  • 00:57:30
    people have a link directly to that the
  • 00:57:32
    book is over 250 pages or actually 250
  • 00:57:37
    pages basically divided into those five
  • 00:57:40
    different areas so fundamentally
  • 00:57:42
    teaching each of those principles like
  • 00:57:44
    that you can see some of the figures I
  • 00:57:46
    showed it basically the teaching manual
  • 00:57:48
    for GI function and then there's a
  • 00:57:51
    series of monographs at the end they
  • 00:57:53
    go through things like feeble IBS IBD h
  • 00:57:57
    pylori etc and going through sort of
  • 00:58:01
    summarizing the the evidence for the
  • 00:58:04
    traditional and the functional approach
  • 00:58:07
    to treating those so the goal of the
  • 00:58:10
    book is really to bring together the
  • 00:58:12
    evidence for the common functional
  • 00:58:14
    medicine approach to these in some cases
  • 00:58:18
    you know we show the evidence in some
  • 00:58:20
    cases we suggest like we did today that
  • 00:58:21
    there's good you know fundamental
  • 00:58:25
    mechanisms but we don't have what we'd
  • 00:58:27
    like to have as far as you know a deep
  • 00:58:29
    clinical trial evidence for some of the
  • 00:58:32
    things that we often use great and and
  • 00:58:35
    just thank you so much again in the
  • 00:58:37
    interest of time we're gonna end our
  • 00:58:38
    question and answer period there for any
  • 00:58:41
    additional educational materials we'd
  • 00:58:43
    like to encourage you to visit our
  • 00:58:44
    website www.investmentpitch.com
  • 00:59:26
    it was my pleasure to be with you
