| + | |||
| + | |||
| + | Thank you John, and thank you to the academy for inviting me to | ||
| + | come. | ||
| + | |||
| + | Well the first two slides are just links to some of the papers that | ||
| + | we've published on these topics. They are there for your references. | ||
| + | |||
| + | Our FDA coordinator also told me to make sure that I point out | ||
| + | that there are FDA applications current for both Sarcoidosis, | ||
| + | designations in the drugs in Sarcoidosis, | ||
| + | Treatment Lyme Disease Syndrome(what most of you would know | ||
| + | as chronic Lyme) active; and the numbers are all at the bottom | ||
| + | and you can find a copies of all of those applications on the | ||
| + | Internet if you want to look in more detail at the regulatory issues. | ||
| + | |||
| + | |||
| + | The disclaimers. Many of the disease states that I am going to | ||
| + | cover in this presentation, | ||
| + | generally accepted as being caused by pathogens. Much of this | ||
| + | presentation is based on leading edge science and not on weight | ||
| + | of evidence. The Phase 2 clinical trial is ongoing. | ||
| + | Even when shown the science and the microscopy, some experts | ||
| + | still disagree to the existence of persistent pathogens. | ||
| + | |||
| + | The FDA has now designated trials for long term use of | ||
| + | Minocycline and Clindamycin in the treatment of Sarcoidosis but | ||
| + | not in the other indications I am going to discuss. We are going to | ||
| + | Phase 3 trials over the next year or two. | ||
| + | |||
| + | Now in addition to our previous papers, the list of which I've just | ||
| + | gone through, many of the slides have Pub Med ID numbers on | ||
| + | them. Those are citations to support the science in any specific | ||
| + | slide. So if there is something on a specific slide that you feel I'm | ||
| + | reaching a bit with, make sure you look at the Pub Med ID | ||
| + | citations first. | ||
| + | |||
| + | And there are also a few new slides resulting from recently | ||
| + | published peer review papers which are not in the syllabus and | ||
| + | which have not been reviewed by AAEM. These have that little red | ||
| + | logo at the bottom saying "NOT IN SYLLABUS." | ||
| + | |||
| + | |||
| + | So here is the first one, "Not in Syllabus." | ||
| + | part is in the syllabus but I changed the text on the bottom, as you | ||
| + | will see on the next slide. | ||
| + | |||
| + | The quotation at the top, from a gentleman called John Arbuthnot, | ||
| + | from Sixteen Hundred and Ninety two. Believe it or not, this | ||
| + | quotation really forms the basis of evidence-based medicine. This | ||
| + | is the gentleman that wrote the first book on statistics of the laws | ||
| + | of chance in 1692 and as you would all know, without statistics and | ||
| + | without the concepts of statistics, we wouldn' | ||
| + | evidence-base that we have at the moment. | ||
| + | |||
| + | What John said ... [read quote from slide]. | ||
| + | |||
| + | The primary difference between mathematical science, which is | ||
| + | primarily what I'm going to deal with in this presentation, | ||
| + | evidence-based medicine is that one is definitive and one is | ||
| + | interpretive. Mathematical science tries to define relationships | ||
| + | between metabolites. Tries to define what's going on. Evidence- | ||
| + | based medicine tries to interpret the results of observations in a | ||
| + | reliable manner. | ||
| + | |||
| + | As we enter the 21st century, the tools to reduce some important | ||
| + | medical dilemma to mathematical precision are now available in | ||
| + | Molecular Genomics. Now one thing I want to point out is that | ||
| + | true science has no concept of weight of evidence. It doesn' | ||
| + | matter how many times you add up the balance in your checking | ||
| + | account, you can start at the bottom of the page and work up, you | ||
| + | can start at the top of the page and work down, the numbers you | ||
| + | are going to get are exactly the same and any body who has done | ||
| + | high school arithmetic can sit down and check your calculations | ||
| + | for you. So therefore, there is no need for weight of evidence. | ||
| + | |||
| + | As a hypothesis is advanced, it can be tested and it stands until it is | ||
| + | rejected or improved. E=MC2 has been improved many times | ||
| + | over the years, but the basic E=MC2 is still there, still in place. | ||
| + | If the problem is deterministic, | ||
| + | |||
| + | This is a new slide, and as an example of how molecular and | ||
| + | evidence-based knowledge are symbiotic and the need for both | ||
| + | fields to work in closer cooperation, | ||
| + | published my answer to a question which had been posed in July | ||
| + | |||
| + | |||
| + | (2006) by Dr DS Grimes. Dr Grimes posed the hypothesis, "Are | ||
| + | statins analogues of Vitamin D?" | ||
| + | |||
| + | |||
| + | Now that's my paraphrase and I'm being a little bit cruel but I | ||
| + | wanted to give you a quick encapsulation of what the hypothesis is | ||
| + | about. This is a hypothesis which cannot be solved by evidence- | ||
| + | based medicine. It cannot be solved because the variables that are | ||
| + | involved, the number of variables that are involved is too high and | ||
| + | they are not appreciated by the investigator. | ||
| + | |||
| + | When you have too many degrees of freedom, your statistical | ||
| + | analyses of the epidemiology just break down. However, the | ||
| + | evidence-based dilemma is easily solved by Molecular Biology and | ||
| + | I'll show you this later in the presentation. I'm going to be talking | ||
| + | about statins. That was actually in the syllabus. | ||
| + | |||
| + | |||
| + | But I wanted to point out that biochemists are also failing. [Read | ||
| + | slide to ' | ||
| + | [Continue reading slide to knowledge] Yet the insights that are | ||
| + | resulting from science that the biochemists are producing [continue | ||
| + | slide]. | ||
| + | |||
| + | First I need to say little bit about Th1 inflammatory disease. [Read | ||
| + | slide first Paragraph] | ||
| + | Unfortunately, | ||
| + | only in the tissues and it's not an endocrine hormone. It doesn' | ||
| + | circulate through the bloodstream. [Read 2nd Paragraph to tissue] | ||
| + | if you want to do a biopsy [finish 2nd Paragraph]. | ||
| + | |||
| + | Consequently, | ||
| + | historically been measured in order to try and infer whether a | ||
| + | patient is presenting with a type Th1 inflammation, | ||
| + | inflammation. A type Th1 inflammation is typically those which | ||
| + | result from infection, such as Tuberculosis, | ||
| + | those are Th1 or they cause Th1 immune responses. Th2 is more | ||
| + | typically those which result from what we call allergies. However, | ||
| + | none of these other cytokine are specific and this has led to | ||
| + | considerable confusion. People think in terms of Th1 and Th2, but | ||
| + | basically all of the autoimmune diseases are Th1. | ||
| + | |||
| + | Louis Pasteur once noted that in science, chance favors the | ||
| + | prepared mind. There are 2 factors: Chance, it's all based on luck | ||
| + | (chuckle), being in the right place at the right time. But the | ||
| + | prepared mind is important. You have to be able to observe what | ||
| + | you see, when you are there. We were lucky, we were able to | ||
| + | break that particular nexus and realized that all of these diseases | ||
| + | we were dealing with were in fact, Th1 diseases. | ||
| + | |||
| + | ... Suicidal idealation, this is not something I've heard anybody | ||
| + | speak about, so far at the conference. It's a big problem with us. | ||
| + | As the immunopathology takes over, the cytokine storm hits. | ||
| + | Suicidal idealationoccurs in a significant number of these people | ||
| + | and it's treatable. As a matter of fact, it's avoidable. | ||
| + | |||
| + | Now those of you that know about the Marshall Protocol and have | ||
| + | been following what we have been doing over the last five or six | ||
| + | years would know that we've conducted this on the Internet as an | ||
| + | open study. Any physician such as yourselves can register and get | ||
| + | full access to the database of all the reporting from the patients in | ||
| + | the study going right back to day one, right back to about 2001. | ||
| + | A year ago, this was heresy. Everybody said you can't do an open | ||
| + | study. You can't do an adaptive study. You can't change the | ||
| + | conditions as you are going along. You can't do anything on the | ||
| + | Internet. | ||
| + | |||
| + | Well, things change. The drug pipeline is now nearly empty and | ||
| + | the FDA is getting quite concerned that not only is the drug | ||
| + | pipeline nearly empty, but the drugs that are there don't work | ||
| + | properly anyway. | ||
| + | |||
| + | And so I put a quote in there now which is given by the FDA | ||
| + | Deputy Commissioner for Medical and Scientific Affairs, who is | ||
| + | actually in charge of clinical trial evaluation at the FDA, Dr Scott | ||
| + | Gottlieb, from an actual conference that was held earlier this year | ||
| + | on adaptive trial design. And basically, I'll save time by saying that | ||
| + | he says [paraphrase] " | ||
| + | these things, guys." And whenever I read the stuff he writes, it | ||
| + | makes me think of the things we are doing. | ||
| + | |||
| + | Now we published our initial results in 2004 in the Th1 syndrome | ||
| + | called Sarcoidosis. Sarcoidosis is a rare disease and it's a disease | ||
| + | that we chose to investigate first. We were lucky to choose this | ||
| + | one, it happens to be a prototypical case for all of the Th1 | ||
| + | diseases. And there are a number of things in Sarcoidosis which | ||
| + | makes the analysis of the disease state very much easier than it is | ||
| + | in some of the more complex conditions. | ||
| + | And in particular, by the time the inflammation has advanced to | ||
| + | the stage where it forms self-perpetuating granuloma, there are | ||
| + | very few antibodies being formed. So there is no longer the red | ||
| + | herring of the antibody formation and perhaps the antibodies | ||
| + | making people sick. We knew the antibodies weren' | ||
| + | people sick because there weren' | ||
| + | something else that was making people sick, probably a cytokine | ||
| + | storm. Where was it coming from? | ||
| + | |||
| + | That was the other Pasteur piece of luck. We happened to be | ||
| + | studying the correct disease that turned out to be the prototype for | ||
| + | many, many other Th1 diseases. | ||
| + | |||
| + | So at Karolinska institutet in Stokholm, at DMM 2006, I gave the | ||
| + | following figures for the recovery rate in several key autoimmune | ||
| + | diagnoses. These were extracted from the Phase 2 and 3 reports. | ||
| + | These are people that have mainly been on the protocol for twelve | ||
| + | months or so on average. | ||
| + | |||
| + | As you can see, Rheumatoid Arthritis has very good success. Eight | ||
| + | have a primary diagnosis of Rheumatoid Arthritis, seven of them | ||
| + | are reporting improvement in their condition. | ||
| + | |||
| + | With Hashimoto' | ||
| + | supplements or they don't. There the ratio is twenty out of twenty- | ||
| + | five are improving. | ||
| + | |||
| + | Osteo Arthritis is an interesting one. I was surprised how many | ||
| + | people with Osteo Arthritis we had in the cohort. | ||
| + | And then the ones that we are known for: CFS/ | ||
| + | Encephalmyelitis. Let me stick with Chronic Fatigue Syndrome. | ||
| + | Seventy-seven with about forty reporting ongoing resolution. | ||
| + | Cardiac Arrhythmia is an interesting one. This came up in a case | ||
| + | study yesterday. And I would like to have an opportunity to join this | ||
| + | group again in about five years time when we have more data and | ||
| + | a lot more history under our belts. And talking again about | ||
| + | cardiac arrhythmia, this is a very classic symptom of late stage Th1 | ||
| + | disease. | ||
| + | |||
| + | Sarcoidosis of course, ninety-two with fifty seven recovering. | ||
| + | |||
| + | Diabetes, five and three. | ||
| + | |||
| + | Uveitis, eighteen and twelve. | ||
| + | |||
| + | 34/20 in Fibromyalgia and 10/8 in Irritable bowel syndrome. | ||
| + | It is an open study, we don't put any preselection conditions on the | ||
| + | patients that want to join, and that's why we have accumulated | ||
| + | such a wide range of diagnoses. There are about 500 patients at | ||
| + | the moment that are regularly reporting and about ten times that | ||
| + | number that we are aware of... of course, that don't report. | ||
| + | |||
| + | There are a few more diagnoses on this slide. It is in your syllabus | ||
| + | so I won't go over them in too much detail. Point out Psoriatic | ||
| + | Arthritis is a new one, also Multiple Sclerosis. We have quite a few | ||
| + | Multiple Sclerosis patients now, at least it is getting up to statistical | ||
| + | significance. Most of those are being looked after by Dr Greg | ||
| + | Blaney in Canada. | ||
| + | |||
| + | Tinnitus resolves. Usually acute Tinnitus resolves quite quickly and | ||
| + | then takes quite a lot longer to resolve fully, several years to | ||
| + | resolve fully. Like peripheral neuropathy, Tinnitus is one of the slow | ||
| + | symptoms to resolve. | ||
| + | |||
| + | Juvenile ADHD, I've got two out of two and I've already chatted | ||
| + | with the autism, the people that are interested in autism. That was | ||
| + | quite a surprise to us. Both of those patients had primary diagnosis | ||
| + | in other areas. One had a Lyme disease diagnosis, the other had | ||
| + | Sarcoidosis and Uveitis diagnosis. The uveitis being key there. The | ||
| + | patient was going blind. All of the problems have resolved. As the | ||
| + | primary inflammatory diagnosis resolved, the attention and other | ||
| + | problems, psychological problems, resolved as well. Resolved | ||
| + | spectacularly. Both are back at school and doing very well. | ||
| + | |||
| + | Well, five steps basically. [Read to end of step 2] | ||
| + | Olmesartan is licensed for sale throughout the world as an | ||
| + | angiotensin-receptor blocker. But it has significant activity in other | ||
| + | receptors. One of the receptors it is very active in is the VDR. It | ||
| + | activates the VDR. | ||
| + | |||
| + | [Read step 3, to " | ||
| + | 48 hours it is usually all they can handle. And then increasing to | ||
| + | 100mg over about three months. | ||
| + | |||
| + | [Read step 4] The choice is made based on suicidal ideation. | ||
| + | Clindamycin tends to exacerbate any suicidal ideation or | ||
| + | depression that is present and we avoid it in the early stages of the | ||
| + | protocol with people who have that tendency. | ||
| + | |||
| + | [Read step 5 to 3 antibiotic combo] "Low dose?", | ||
| + | Azythromycin, | ||
| + | days when they start. They eventually work up to about half of an | ||
| + | Azythromycin tablet as ultimately the bacterial load is totally | ||
| + | removed, and then they can just guzzle the antibiotic like candy, | ||
| + | like a healthy person can. | ||
| + | |||
| + | But initially, when the immune system is working, those antibiotics | ||
| + | do an incredible job of killing the bacteria. | ||
| + | |||
| + | |||
| + | So, this was a warning that my FDA liaison — contact — said | ||
| + | " | ||
| + | |||
| + | [Read warning to apoptosis] programmed cell death [continue | ||
| + | warning]. | ||
| + | |||
| + | Immunopathology. That is the word that is being used instead of | ||
| + | " | ||
| + | cytokine storm that occurs in acute episodes. " | ||
| + | first heard Rolf Zinkernagle use it at Karolinska and it is becoming | ||
| + | more and more commonly used. It is basically what happens to | ||
| + | the body when the immune system is doing its job. It includes | ||
| + | apoptosis, cytokene storm, all of the other effects on the body from | ||
| + | the immune system doing its job. Immunopathology. | ||
| + | [Read Steps needed]. | ||
| + | |||
| + | The moment pathogens start being recognized and start being | ||
| + | killed, your white and red blood cell counts are going to go all | ||
| + | over the place. | ||
| + | |||
| + | [Read Step 1 to receptors], which is rather handy to reduces | ||
| + | fibriotic tissue deposition. | ||
| + | |||
| + | Now we use special antibiotics. You might not think they are | ||
| + | special, but they are special in their interaction. The antibiotics | ||
| + | have a direct action on a part of the bacterial genome which is | ||
| + | called the ribosome. The ribosome, if you cast your mind back to | ||
| + | molecular biology, is where the messenger RNA from gene | ||
| + | transcription, | ||
| + | |||
| + | In bacteria, they only have one ribosome. The human body has | ||
| + | two ribosomes. Bacteria only have one, called the 70S ribosome, | ||
| + | and the antibiotics that we use block the action of the 70S | ||
| + | ribosome. They block the ability of the bacteria to produce protein. | ||
| + | Particularly to use the protein that they use to evade the immune | ||
| + | system. Because clearly, the bacteria wouldn' | ||
| + | within the phagocytes unless they had a mechanism evolved | ||
| + | probably over centuries that allows them to evade phagocytosis. | ||
| + | So the rate of bacterial death is controlled by inhibiting the protein | ||
| + | synthesis, using only intermittent low doses of bacteriostatic | ||
| + | antibiotics. | ||
| + | |||
| + | The other advantage of going after the ribosome is a small | ||
| + | amount of antibiotics kills a small number of bacteria. In fact, one | ||
| + | molecule binds into one ribosome. So it is not quite linear, but it is | ||
| + | a proportional response. | ||
| + | |||
| + | So why? Why does this intervention work when all the previous | ||
| + | antibiotic therapies used for these diseases didn't induce recovery? | ||
| + | |||
| + | [Read 1] | ||
| + | In other words, there is a model. We can fit the disease that we | ||
| + | observe to a model. So when I say that five MS patients is a good | ||
| + | sized sample, its because they are behaving exactly as the model | ||
| + | predicts. So we have the extra statistical guidance from the model | ||
| + | as well as from the data. | ||
| + | |||
| + | It works because [Read 2]. | ||
| + | [Read 3] The VDR, which was long thought to be ' | ||
| + | with ' | ||
| + | immunity. And I'll talk a LOT more about this as we go forward. | ||
| + | [emphasis repeat] Vitamin D is at the heart of innate immunity. | ||
| + | [Read 4]. That is part of the model. We have to know how the | ||
| + | people get sick, and how the sickness progresses over the years. | ||
| + | [Reference 5]. For example, sequencing the bacterial genomes | ||
| + | have shown that many of the common bacteria, even Staph | ||
| + | aurious, has got plasmids. Plasmids are little self-replicating loops | ||
| + | or sticks of DNA that can exist and replicate on their own without | ||
| + | the main chromosome. And many bacteria have these plasmids. | ||
| + | The plasmids can persist and if they are not destroyed by the | ||
| + | immune system, they can interact with other species of bacteria. | ||
| + | Toward the end, I will show you exactly how that happens with a | ||
| + | bacterium species called antrhax. | ||
| + | |||
| + | So the plasmids are persistent and prolific. So when you have a | ||
| + | chronic disease which is accumulating over a lifetime, certainly | ||
| + | over many years, you're not going to have just one species that is | ||
| + | active. You are going to have a number of species that are active. | ||
| + | You are going to have a number of plasmids that are active. You | ||
| + | are going to have a number of viruses that are active. | ||
| + | The ubiquitous EBV. I think I can find a paper for just about any | ||
| + | disease you like name which blames EBV as the cause of that | ||
| + | disease. No. But EBV is very hard to kill off. Its plasmids is just two | ||
| + | genomes long; something like a 160,000 base pairs long; it's very, | ||
| + | very small; very, very hard for the immune system to recognize and | ||
| + | kill; and it persists. And it interacts with any other species of | ||
| + | pathogens in exactly the same way as it interacts with the human | ||
| + | genome. And it will cause mutations. The bacteria cause | ||
| + | mutations. | ||
| + | |||
| + | And the last reason the intervention works is [reference 6] because | ||
| + | the MODEL recognizes that neo-natal pathogens persist in the | ||
| + | brain. [Repeat intended] Neo-natal pathogens persist in the brain. | ||
| + | |||
| + | Well, now we get into some pretty pictures. | ||
| + | These are pictures of a receptor, it is a G-Protein Coupled | ||
| + | Receptor that goes through a membrane. And each of the little | ||
| + | colored balls are atoms. Each of the similarly colored atoms form | ||
| + | part of an amino acid, which together make the protein which is | ||
| + | folded into the receptor. | ||
| + | |||
| + | Well it's not very easy analyzing that sort of diagram, so | ||
| + | biochemists tend to draw everything in terms of spirals and loops. | ||
| + | Each one of these spirals is a cascade of amino acids. It is shown | ||
| + | diagramatically as a spiral so that we can see more easily what it | ||
| + | is actually doing. | ||
| + | |||
| + | We also have a more precise 2-dimensional representation that | ||
| + | you will find in some of my papers. And here we have the actual | ||
| + | amino acid of the protein (see lower right "Leu 293" highlighted in | ||
| + | video) and it shows which are the atoms or ligand of the chemical. | ||
| + | In this case it is olmesartan but it could be any of the vitamins D. | ||
| + | It shows which of the atoms interact with the ammino acid residues | ||
| + | (see lower right O1 red atom highlighted in video), and it also | ||
| + | shows the hydrogen bonds when they exist as well. Making it very | ||
| + | easy to try and figure out whether we are dealing with an agonist, | ||
| + | or an ANtagonist. Much harder to do that in 3-dimensions. | ||
| + | |||
| + | |||
| + | I want to talk about the nuclear receptor type one family because it | ||
| + | turns out that this family is most closely related to the operation of | ||
| + | the immune system — both the innate immune system, and the | ||
| + | adaptive immune system. | ||
| + | |||
| + | The key receptors for which we have known structure models. In | ||
| + | other words, we not only know that the bacterial genome looks like | ||
| + | this but we also know in 3-dimensional space that x-ray | ||
| + | spectroscopy has told us exactly where each atom is in the | ||
| + | molecule. In this case, we're talking about the human genome. But | ||
| + | it's the same theory, we've got the VDR (Vitamin D Receptor), the | ||
| + | Progesterone Receptor, PPAR-alpha (which is one of the lipid and | ||
| + | immune system mediators), PPAR-gamma (which is also lipid and | ||
| + | immune system), Androgen Receptor, the Estrogen Receptor, | ||
| + | glucocorticoid receptor, Thyroid-alpha-1, | ||
| + | mineralcorticoid receptor. | ||
| + | |||
| + | Now surprisingly, | ||
| + | as spirals (I guess maybe I should have done a slide of it for you), | ||
| + | but they are all very, very similar. And that is why they are the type | ||
| + | 1 nuclear receptors. | ||
| + | |||
| + | And you know molecules that will go into the VDR usually only go | ||
| + | into PPAR-gamma and some of the other type 1 receptors as well. | ||
| + | They affect more than one function of the body. | ||
| + | |||
| + | |||
| + | So nuclear receptors are responsible for the transcription of the | ||
| + | DNA genes to strands of RNA, which are then translated into | ||
| + | proteins in the ribosomes. And they are very important. | ||
| + | I've put a link there to a simplified set of flash animations for those | ||
| + | of you that want a crash course on how this all works. It is a very | ||
| + | simple crash course. I really recommend you have a look at it. | ||
| + | (https:// | ||
| + | |||
| + | |||
| + | Now we're going to look at some simplified 3-D animations of the | ||
| + | transcription molecules, just to give us an overview. | ||
| + | |||
| + | What we have here, we have a strand or double strand of DNA | ||
| + | (highlight blue/ | ||
| + | are the base pairs that run across (highlight on video shows | ||
| + | vertical ball lines at bottom center of diagram) the two backbones | ||
| + | of the DNA. Across the center you have the hydrogen bonds that | ||
| + | hold the DNA together (highlight moves L-R across center of | ||
| + | vertical ball lines). Hydrogen bonds that are peeled apart is when | ||
| + | the RNA is produced. The RNA is basically ½ of the DNA double | ||
| + | spiral. | ||
| + | |||
| + | So when the nuclear receptors do their job and transcribe a gene, | ||
| + | what they are actually doing is breaking the hydrogen bonds and | ||
| + | producing the RNA in a very complex and clever fashion which | ||
| + | doesn' | ||
| + | statistically drift around and come together in exactly the right way. | ||
| + | Nuclear receptors typically take days to effect their action. | ||
| + | Key to nuclear receptors are the zinc fingers here (video highlights | ||
| + | upper left center large yellow/ | ||
| + | zinc, the yellow, sulpher-disulfides. Actually cystines to be honest. | ||
| + | And they are a key part to positioning the helixes which go through | ||
| + | the (video highlights lower left solid light grey spiral) DNA and find | ||
| + | the exact chain that needs to be translated based on the exact | ||
| + | mapping of attractive and repulsive forces and then do the DNA | ||
| + | transcription. | ||
| + | |||
| + | It is an amazing system. I've shown here that there two receptors | ||
| + | because usually one nuclear receptor doesn' | ||
| + | form a homodimer but it usually forms a Heterodimer. So you have | ||
| + | a VDR coupled with a retinoid-X receptor and then the two of them | ||
| + | transcribe genes. There is also a cofacter that gets involved as | ||
| + | well. Quite complex and we really don't know a lot about it yet. | ||
| + | I mean we now have the genes to transcribe, but we don't know | ||
| + | exactly which co-factors go with which receptors. | ||
| + | |||
| + | |||
| + | The biggest surprise we got when we started doing this modeling, | ||
| + | was the high affinity of the ARBs and Statins for VDR and PPAR- | ||
| + | gamma, Nuclear Receptors which are both key to the immune | ||
| + | system. | ||
| + | |||
| + | Now these are very flexible, highly polar ligands. And we thought | ||
| + | they might have an affinity for other G-protein coupled receptor | ||
| + | membrane receptors, in other words receptors that go through a | ||
| + | membrane rather than exist in the nucleus of the atom. | ||
| + | |||
| + | But their affinity for the Nuclear receptors was a real surprise. | ||
| + | |||
| + | |||
| + | Here's a big table which represents months of computing. | ||
| + | But what we have done here is used special software that | ||
| + | computes the interaction between thousands of atoms and figures | ||
| + | out for each of the (video highlights drug names in the sartan | ||
| + | group) ARBs and each of the Statins (video highlights drug names | ||
| + | in the statin group), which receptors they are going to have an | ||
| + | affinity for — if any — and which receptors they are going to | ||
| + | switch on or switch off. | ||
| + | |||
| + | And if we just look at the statins first, thinking back to the question | ||
| + | posed by Grimes in The Lancet: "Are statins analogues of vitamin | ||
| + | D?" Well the first thing that pops out is that the VDR here (video | ||
| + | |||
| + | highlights VDR column head), there is a huge difference between | ||
| + | the statins. | ||
| + | |||
| + | Simvastatin (video highlights 4 at base of the VDR column) hs got | ||
| + | quite a low number which means quite a high affinity, but | ||
| + | Rosuvastatin, | ||
| + | have any affinity for the VDR at all. Pravastatin that is effectively no | ||
| + | affinity. Lovastatin would have a little affinity if a low dose is used | ||
| + | in vivo. | ||
| + | |||
| + | So there is a huge difference between the statins. Just thinking of | ||
| + | |||
| + | the statins as a group is a concept that is dangerous clinically, let | ||
| + | alone to try and extrapolate that to talking about the statins | ||
| + | functioning as a hormone would. | ||
| + | |||
| + | But you can also see if you take Simvastatin, | ||
| + | a high affinity for the VDR, it's got 10x higher affinity for the PPAR- | ||
| + | gamma, same for PPAR-alpha as the VDR. The Gluco-corticoid | ||
| + | receptor -the home for cortisole- it has a high affinity for, also the | ||
| + | MCR. The Progesterone receptor, the Alpha-Thyroid and the Beta- | ||
| + | Thyroid. Simvastatin is a very, very active statin. | ||
| + | |||
| + | Whereas Atorvastatin for example, primarily hits PPAR-gamma and | ||
| + | alpha and incidently hits the Gluco-cortisole axis for the GCR. | ||
| + | However, some of the ARBs are a little bit better behaved than that. | ||
| + | Telmisartan is very poorly behaved. It totally shuts off the VDR the | ||
| + | moment you give it to somebody. This is NOT good. | ||
| + | |||
| + | Olmesartan, here (video highlights 10 in the VDR column) has got | ||
| + | a moderately low affinity for the VDR, and that is one of the | ||
| + | reasons why we have to use a higher dose when we are using it to | ||
| + | modify the VDR than when we are modifying the Angiotensen- | ||
| + | receptor where it has a much higher affinity. But it is nicely | ||
| + | controlled in the PPAR-gamma and -alpha (video highlight across | ||
| + | Olmesartan Estimated Ki row) and GCR. It hits the progestrone | ||
| + | receptor but it doesn' | ||
| + | |||
| + | Beta-Thyroid it hits but we're not really sure what Beta-Thyroiod | ||
| + | does yet. What we know about Beta Thyroid is that if you breed | ||
| + | mice that don't have the beta thyroid receptor, then they are born | ||
| + | deaf. Otherwise they seem to be fine. (Audience chuckles) So we're | ||
| + | still trying to figure out what the Beta Thyroid does. | ||
| + | |||
| + | The ability to breed mice with gene knock-outs without these | ||
| + | receptors is a PRIMARY new tool that has become available to the | ||
| + | biochemist. It is invaluable. Unfortunately with the GCR, if you | ||
| + | knock out the GCR the mice never survive past gestation. So we | ||
| + | don't know a heck of a lot about the GCR either except it is at the | ||
| + | root of the Cortisole axis of the adrenal. | ||
| + | |||
| + | But anyway, it is a big table and I have it printed on a sheet of | ||
| + | paper and I have to refer to it all the time, so I'm not going to | ||
| + | expect any of you to commit that to memory. | ||
| + | |||
| + | Now I'm going to look at a very simple hormonal system. The | ||
| + | adrenal axis. And up here (video highlights top word | ||
| + | " | ||
| + | looking at the GlucoCortocoid Receptor, the nuclear receptor, with | ||
| + | a promotor which is " | ||
| + | receptors, and then the promotor and the receptor together bind | ||
| + | to the DNA and transcribe the gene. | ||
| + | |||
| + | The GlucoCortocoid Receptor is responsible for producing | ||
| + | Corticotrophin Releasing Hormone (CRH highlighted), | ||
| + | turn produces the Pro-Opeo-Milleno Cortin and when that is | ||
| + | metabolized, | ||
| + | produced. ACTH of course you know, that catalyzes the conversion | ||
| + | of Cholesterol into Cortisol. Then Cortisol goes up and docs into | ||
| + | the GlucoCortocoid Receptor (highlight shows arrow line path left | ||
| + | and up to GCR) and you have a feedback loop, which keeps the | ||
| + | Cortisol levels of the body at roughly constant levels. | ||
| + | That is a very simple, straight forward hormone loop. | ||
| + | |||
| + | |||
| + | Unfortunately, | ||
| + | would expect for something that is at the heart of the immune | ||
| + | system. It has adapted over many, many millennia. | ||
| + | The "not in Syllabus" | ||
| + | shifted from what is printed in your syllabus. Also, since that | ||
| + | syllabus was published, there has been new studies showing that | ||
| + | the Androgens (video highlights lower left corner word | ||
| + | " | ||
| + | 1,25-D by the enzyme CYP24. | ||
| + | |||
| + | But basically, the body starts off with 7-dehydro-Cholesterol, | ||
| + | is part of the sterol subsystem. It is a cholesterol derivative (video | ||
| + | highlights upper left 7-dehydro-Cholesterol), | ||
| + | to pre-Vitamin D by energy. Conventionally thought to be UVB, but | ||
| + | the biochemists will easily tell you it doesn' | ||
| + | can even be an enzyme. Enzyme at this point, we have no idea | ||
| + | what that enzyme would be if it is an enzyme. But it certainly | ||
| + | doesn' | ||
| + | highlighted). All you need is a contra-rotatory electrocyclic reaction | ||
| + | which occurs in other substances and which is pretty well | ||
| + | characterized. | ||
| + | |||
| + | (Vitamin D highlighted) Then, Pre-Vitamin D is formed into Vitamin | ||
| + | D by a Sigmatrophic shift. A very small shift of the electrons (????). | ||
| + | Vitamin D is converted by the enzyme CYP27A1 -or- CYP2R1 and | ||
| + | both of these are P450 digestive system enzymes into 25- | ||
| + | hydroxyvitamin-D (highlight drops to 25-hydroxyvitamin-D) and this | ||
| + | is the one that most of you are measuring when you measure | ||
| + | somebody' | ||
| + | the 25-hydroxyvitamin-D. | ||
| + | |||
| + | (Highlight drops to 1, | ||
| + | converted to 1, | ||
| + | either CYP27A1 or CYP27B1, both of them will hydroxyllate. And | ||
| + | that 1, | ||
| + | *activate*) the VDR and allow the VDR to do the gene transcription | ||
| + | that is at the heart of innate immunity. | ||
| + | |||
| + | |||
| + | And then finally, the 1,25-D is inactivated (highlight opens on | ||
| + | lower left " | ||
| + | CYP24 enzyme so that you don't end up with too much of it in the | ||
| + | body. | ||
| + | |||
| + | And that is what goes wrong in Th1 disease. You end up with too | ||
| + | much 1,25-D in the body because the VDR inactivation path — | ||
| + | something goes wrong with it. | ||
| + | |||
| + | |||
| + | Well, OK. Here we have some pretty pictures. We have atoms and | ||
| + | bonds. The grey atoms (highlight upper left picture, left grey atom | ||
| + | selected highlight in video) are carbons, the red ones are oxygen, | ||
| + | that green is a fluorine, That's a hydroxy OH there (highlight | ||
| + | moving from green to lower center red/grey center bottom), the | ||
| + | light blue is the H of the hydroxy. And this molecule is | ||
| + | Dexamethasone in exactly the configuration where it binds into the | ||
| + | Gluco-Corticoid Receptor (GCR binding pocket), you know the | ||
| + | adrenal axis, the Gluco-corticoid receptor. | ||
| + | |||
| + | And here (video highlights lower right figure center), we see 1,25- | ||
| + | Dihydroxyvitamin D competing with Dexamethasone for the | ||
| + | binding pocket of the GlucoCortocoid receptor. | ||
| + | |||
| + | 1,25-D has a very high affinity for the adrenal axis. This is new, it | ||
| + | is not in the syllabus, it's taken from a paper which was accepted | ||
| + | for the nuclear receptors conference next week, actually. | ||
| + | |||
| + | |||
| + | So what does that mean? If we go back to our nice simple adrenal | ||
| + | axis, what does that mean? | ||
| + | |||
| + | Well it means that (highlight focuses on top black box 25-D and | ||
| + | 1,25-D) 25-D and 1,25-D can both bind into the GlucoCortocoid | ||
| + | Receptor and displace Cortisol from doing that. | ||
| + | |||
| + | When it does that, the amount of CRH and particularly ACTH is | ||
| + | down regulated, and you end up with Adrenal Insufficiency | ||
| + | (highlight on lower black box " | ||
| + | |||
| + | |||
| + | OK, the vitamins D also compete for the Thyroid binding pocket. | ||
| + | I'm talking about the alpha thyroid here, the important one. | ||
| + | There we have T3 as it docs into the alpha thyroid to activate the | ||
| + | alpha thyroid (highlight shows green end molecules on the top left | ||
| + | illustration). These are the iodine molecules, three of them of | ||
| + | course. | ||
| + | |||
| + | Here we have 1,25-D competing (highlight center of lower R | ||
| + | figure) with T3 for the alpha thyroid Binding Pocket. It wants to | ||
| + | dock in exactly the same binding pockets as the T3 would. And by | ||
| + | doing that in high enough concentration, | ||
| + | |||
| + | binding. It will stop the alpha thyroid from working properly. | ||
| + | We end up with, among other things, hypothyroidism. | ||
| + | |||
| + | So I've done a summary slide here of the operation of the VDR. It | ||
| + | is key to both the endocrine and immune systems. | ||
| + | The VDR is responsible for decreasing parathyroid Hormone | ||
| + | Transcription. [Reference slide to TLR4], and therefore the | ||
| + | bacterial response. | ||
| + | |||
| + | Toll-like Receptor 4 is responsible for sensing | ||
| + | lipopolysaccarhride. Toll-like Receptor 2 is responsible for | ||
| + | sensing the presence of other bacteria protein. When the VDR is | ||
| + | not working, because you have administered vitamin D and are | ||
| + | experiencing the immuno suppressive action of the vitamin D, | ||
| + | when the VDR is not working, you do not have a functioning TLR2 | ||
| + | and TLR4 system. | ||
| + | |||
| + | But you also lose the antimicrobial peptides. It transcribes the | ||
| + | cathelicidin antimicrobial peptide (cAMP) and it's also responsible | ||
| + | for beta defensins. The beta defensins are absolutely key to the | ||
| + | proper operation of small intestine. The small intestine, in fact, | ||
| + | the whole GI tract is critically dependent on the defensins and | ||
| + | especially the beta defensins and the cathelicidins to work | ||
| + | properly. When you knock out the VDR with immunosupression | ||
| + | — either a steroid or ' | ||
| + | And finally, the VDR is responsible for binding the interluken 2 | ||
| + | (IL2) promoter. Now you all probably know that you measure | ||
| + | interluken 2 when you want to measure a Th1 reaction. Well, that | ||
| + | is why, because the VDR actually produces the interluken 2, even | ||
| + | if you can't measure it. | ||
| + | |||
| + | I've got some other functions there, I guess the main one there is | ||
| + | it regulates the TACO gene, which is responsible for | ||
| + | mycobacterium tuberculosis intraphagocytic survival, and it | ||
| + | promotes transcription of Insulin Receptors. | ||
| + | |||
| + | Let's skip the rest because we're running a little late bit short in | ||
| + | time. | ||
| + | |||
| + | |||
| + | The current status of the VDR is that the VDR is responsible for | ||
| + | TLR2 and TLR4 expression, as well as cAMP... hey, I just said that | ||
| + | on the previous slide! Sorry. | ||
| + | |||
| + | What we've got here is two pictures and we have all the vitamin | ||
| + | D's (video highlights left image) superimposed. We've got 1,25- | ||
| + | Dihydroxyvitamin-D, | ||
| + | (highlight arrow and red atom in lower right of left image) here, | ||
| + | the only one that can activate the VDR. Various other atoms can | ||
| + | activate the GCR or de-activate the GCR and the thyroid, but the | ||
| + | only one that will activate the VDR is this one (highlight again on | ||
| + | arrow and red atom) on the 1, | ||
| + | all the vitamins D fit into the receptor in almost identical | ||
| + | positions. Whether it is 24,25-D, 25,26-D or 1,25-D. Even | ||
| + | vitamin D itself fits in there as well and they are all competitive. | ||
| + | If you're giving people 40mg, if you're giving people vitamin D | ||
| + | such as such as to get the blood concentration at 25-D to 40 | ||
| + | nanograms per ml, then you're sitting with 25-D in most of your | ||
| + | VDRs and they are NOT activated, it is immuno-suppressive. The | ||
| + | patient will feel better short term because the inflammation is | ||
| + | suppressed. Long term, with the bacterial pathogens running right, | ||
| + | it's a different situation. | ||
| + | |||
| + | The picture on the right hand side just shows olmesartan binding | ||
| + | into the VDR pocket and you can see if you look at it carefully, you | ||
| + | can see that the olmesartan hydroxyl here (video highlights upper | ||
| + | right atoms O1 and O2 in lower right of right image) are actual | ||
| + | capable of activating the VDR in the same way as 1,25-D does. | ||
| + | |||
| + | |||
| + | So, we've got some little pictures here. We have 2 molecules. | ||
| + | What we have here is the steroid rings (video highlights right | ||
| + | image, upper right rings of molecule) of prednisone. This is | ||
| + | actually prednisone. | ||
| + | |||
| + | We have the steroid rings of prednisone, and over here (video | ||
| + | highlights middle two rings on left figure) we have the steroid rings | ||
| + | of " | ||
| + | steroid rings.... I want to show you the only difference between the | ||
| + | secosteroid and the steroid is one bond. It's this carbon to carbon | ||
| + | bond across here (highlight shows critical top left ring closure of | ||
| + | right image, in 2nd ring from left). And it is missing across here | ||
| + | (highlight now shows open ring in left image in the 2nd ring from | ||
| + | left) in the seco-steroid. And that is why it is a secosteroid rather | ||
| + | than a steroid. | ||
| + | |||
| + | It is a very subtle change, it actually gives the [vitamin D] [not VDR] | ||
| + | more flexibility to move in a socket and that is one of the reasons | ||
| + | why it binds into so many of the nuclear receptors. The structural | ||
| + | similarity (video highlights cortisone bond again) between | ||
| + | prednisone and vitamin D basically come down to that one carbon | ||
| + | bond. And that is why it is a secosteroid and not a corticosteroid. | ||
| + | |||
| + | So I have a slide here on Vitamin D in Bone Remodeling because I | ||
| + | know all of you are going to say "well, If I withdraw vitamin D from | ||
| + | my patients, their bones are going to get weaker." | ||
| + | some up to date citations you can go away and look at, which | ||
| + | show that actually " | ||
| + | at all. It's the Calcium Sensing Receptor and the Parathyroid | ||
| + | hormone that are responsible for Calcium homeostasis. And | ||
| + | secondly, even the cannabinoid receptors play a key role in bone | ||
| + | remodeling and bone mass. That paper is only a few weeks old. | ||
| + | The sex hormones are also players in bone density, I think you | ||
| + | know that one. | ||
| + | |||
| + | And that elevated levels of 1, | ||
| + | have found to be associated with Th1 immune disease, actually | ||
| + | encourage osteoclastic actions and breakdown of bone and | ||
| + | deposition of bone into soft tissue. The last thing you want in these | ||
| + | patients is high levels of 1, | ||
| + | |||
| + | So this has got a "not in syllabus" | ||
| + | had in the syllabus was a lot more caustic. This is diluted. | ||
| + | |||
| + | Public-Health Consequences of Regarding ' | ||
| + | ' | ||
| + | " | ||
| + | and hormonal activity. And we put the seco-steroid | ||
| + | ' | ||
| + | the rare disease, Rickets. And as physicians, you would know the | ||
| + | side effects from administration of steroids. | ||
| + | |||
| + | So the CDC now says we are heading towards half of all US | ||
| + | seniors being Diabetic by the year 2050. | ||
| + | |||
| + | And, Oh, steroids often induce obesity. I'll leave you to connect the | ||
| + | dots. | ||
| + | |||
| + | I haven' | ||
| + | figure out how Sarcoidosis patients could be made sick in the | ||
| + | absence of antibodies, this paper was published back in late 2001 | ||
| + | on the Internet, and what it showed was Rickettsia Helvetica inside | ||
| + | Phagocytes (video highlights upper right image E at two arrows). | ||
| + | Persistent inside phagocytes, not broken down by phagocytosis but | ||
| + | actually living in the phagocytes of Sarcoidosis patients. | ||
| + | That was the Eureka moment for me. I should have known it, there | ||
| + | is plenty of other literature talking about mycobacterium being | ||
| + | intraphagocytic, | ||
| + | |||
| + | |||
| + | And then the real studies that you all will want to see if you are | ||
| + | interested in the actual pathogens, were the Wirostko Studies from | ||
| + | Columbia University in the late 80's. There are bout 30 or 40 | ||
| + | electron transmisional microscopy photographs showing stained | ||
| + | bacteria. Tiny, tiny colonies (video highlight shows lower left arrow | ||
| + | circle of bacteria, then moves to second to left arrow colony, to | ||
| + | middle arrow pointing to colony and then to upper right arrow) of | ||
| + | stained bacteria in the phagocytes. This is a quarter of a | ||
| + | macrophage. | ||
| + | |||
| + | And they were very thorough, they did macrophages, | ||
| + | lymphocytes and neutrophils. And they found that in the | ||
| + | Sarcoidosis patient, they found the intraphagocytic bacteria | ||
| + | persistent in all of them. | ||
| + | |||
| + | And in fact, the nucleus here (video highlights heavy bolded arrow | ||
| + | left of center pointing to nucleus) is breaking away a little bit near | ||
| + | this larger colony of bacteria (video highlights second lower left | ||
| + | small arrow). That's why it has the big arrow on it. | ||
| + | |||
| + | Fascinating photographs. Very important if you want to understand | ||
| + | the actual bacterial pathogens, the L-forms that cause these | ||
| + | diseases (cell wall deficient bacteria called L-forms for the Lister | ||
| + | institute where they were first identified). They are tiny pathogens. | ||
| + | They are so small. They are hundredths the diameter of the | ||
| + | macrophage. I've got 200 nanometers here (video highlights lower | ||
| + | right slide legend). We're talking about cocciodes, tiny little dots | ||
| + | that are about 10-15 nanometers in diameter. | ||
| + | |||
| + | |||
| + | These are pictures that show the diagrammatically show the | ||
| + | survival of bacteria in the phagocyte. I've covered these in my 30th | ||
| + | anniversary of Lyme meeting and with your permission, I'll skip over | ||
| + | this. You can find it in any book. (because we're running late on | ||
| + | time). | ||
| + | |||
| + | Bacterial protein synthesis, and remember I talked about the 70S | ||
| + | Ribosome, the bacterial Ribosome. Here we actually have the | ||
| + | structure of the bacterial Ribosome, it is primarily made up of RNA, | ||
| + | unlike the human ribosomes which are primarily protein based. | ||
| + | But the 16S RNA (video highlights the lower left 16S rRNA on | ||
| + | figure), which you would all recognize as being the PCR, the | ||
| + | substance which is used as the target for most PCR tests. 16S rRNA | ||
| + | forms the 30S side of the ribosome (video highlights upper left 30S | ||
| + | figure subhead). The top of this 30S we have a heliacal structure | ||
| + | (video highlights top left ribbons) which is responsible for translate | ||
| + | but actually for ... translating the mRNA into a protein. | ||
| + | The actual translation is done on the 50S side, you can see a | ||
| + | protein (video highlights lower right quadrant) coming out the | ||
| + | bottom here and it's in yellow. The protein transferase center | ||
| + | (video highlights middle, slightly right) is right in the center which | ||
| + | you see, and there we have tRNA (video highlights blue grape | ||
| + | cluster mid top) which is donating the amino acid into the growing | ||
| + | protein. | ||
| + | |||
| + | |||
| + | And this is an Xray structure, which was produced from the Max | ||
| + | Planck group in Germany, and this x-ray structure shows a | ||
| + | number of antibiotic molecules found in, you can look at them in | ||
| + | your syllabus', | ||
| + | tetracycline. And in fact, the tetracycline binds right at the top | ||
| + | (video highlights top of 30S Sub-unit, see Orange color), and | ||
| + | inhibits RNA translation. | ||
| + | |||
| + | |||
| + | On the 50S side, you can see how the protein is assembled and | ||
| + | exits the exit tube a little more easily. And in particular, the | ||
| + | important thing is here, you will notice that Clindamycin (video | ||
| + | highlights center formation), just the light orange one, sits right at | ||
| + | the PTC. And the Azythromycin sits a little bit below it, so they are | ||
| + | actually symbiotic antibiotics. | ||
| + | |||
| + | All three antibiotics that we use are symbiotic. That means that | ||
| + | each of them progressively reduces the function of the [bacterial] | ||
| + | ribosome. That means that when you give them together, they are | ||
| + | not competing with each other, they' | ||
| + | symbiotic. Very important. Something that the genome, the | ||
| + | bacterial genome, has told us quite clearly. | ||
| + | |||
| + | |||
| + | So now we talk about the species. | ||
| + | |||
| + | Which species of bugs is it? | ||
| + | |||
| + | Well, it is not a single species. We're dealing with a polymicrobial | ||
| + | disease. If you look at the various diseases, and the bacteria that | ||
| + | have been reported with them all, the common ones like Staph- | ||
| + | aureus and Propionibacterium-acnes, | ||
| + | granulosum, seem to be the ones that crop up most of all, with the | ||
| + | nasty bugs, micobactera cropping up far less frequently. And | ||
| + | certainly less than 100%. | ||
| + | |||
| + | So we're almost certainly dealing with a polymicrobial disease. | ||
| + | And depending on the exact mix of pathogens, determines which | ||
| + | of the Th1 diseases, which of the Th1 symptom syndromes the | ||
| + | patient will progress to. Whether it turns into Rheumatoid Arthritis, | ||
| + | Multiple Sclerosis, or Anorexia Nervosa. | ||
| + | |||
| + | It's become obvious that most bacteria species are not | ||
| + | homogenous. They' | ||
| + | self-replicating plasmids which carry DNA and genes. Borrelia | ||
| + | burgdorferi has got a large number of plasmids, in fact, nearly half | ||
| + | of its genome exists on 21 self-replicating plasmids sub-units. | ||
| + | Now I'm not saying that makes it any more strong of a pathogen, | ||
| + | but it certainly adds quite a lot to the "Pea Soup" which I like to | ||
| + | think of as mix of DNA which accumulates in the chronic diseases. | ||
| + | Yet even Staph. epidermidis gives rise to plasmids. It's got about | ||
| + | 10% of its DNA spread over six self-replicating plasmids. | ||
| + | |||
| + | These can be shared between species. But the plasmids are not | ||
| + | targeted by antibiotics. Antibiotics don't target plasmids. Only the | ||
| + | innate immune system can go after the plasmids. So unless the | ||
| + | plasmids are destroyed by the immune system, they will persist in | ||
| + | chronic intra-cellular infections. | ||
| + | |||
| + | And I think of it as a "DNA Pea-Soup." | ||
| + | |||
| + | |||
| + | Plasmids do transmit DNA horizontally. Notice the citation here, it | ||
| + | was published in the Proceedings of the National Academy of | ||
| + | |||
| + | Sciences in 2004. And what you had was, you had a patient that | ||
| + | got very, very ill with a species of Bacillus cereus. Now, Bacillus | ||
| + | cereus, we all know is a [relatively] harmless bacteria. It's a | ||
| + | Bacillus that doesn' | ||
| + | (video highlights B.cereus yellow circle on figure, upper right of | ||
| + | center). | ||
| + | |||
| + | Whereas just a little bit further around on the phylogeny here, we | ||
| + | have Bacillus-anthracus (video highlights red spike circle far upper | ||
| + | right). And what distinguishes Bacillus-anthracus is 2 plasmids. | ||
| + | One plasmids contains the ability to evade the immune system, the | ||
| + | proteins that give it the ability to evade the immune system, the | ||
| + | other plasmids carries the ability to produce a cytokine storm and | ||
| + | kill the host. | ||
| + | |||
| + | Now what happened in this case was the two plasmids from | ||
| + | anthracus were transferred into cereus and formed an extremely | ||
| + | toxic combination. | ||
| + | |||
| + | |||
| + | And you can see that the mice that were just challenged with | ||
| + | cereus, they all survived (video highlights upper center double red | ||
| + | circles on figure 4). | ||
| + | |||
| + | Those that were challenged with anthrax (video moves down to | ||
| + | yellow circle dropping line) -which color is anthrax? yellow- most | ||
| + | of them died. | ||
| + | |||
| + | BUT they died a lot quicker if they were the hybrid (video highlights | ||
| + | green circle line) of the anthrax plasmids and the cereus genome. | ||
| + | This is a big, big problem! | ||
| + | |||
| + | Why is it a problem? | ||
| + | |||
| + | Well, (video returns to first horizontally slide) if you look further | ||
| + | around on this phylogeny (video highlights B thuringiensis | ||
| + | israeliensis, | ||
| + | thuringiensis Israelensis. That one is sprayed onto agricultural | ||
| + | crops as a herbicide. Sorry, it is an insecticide. | ||
| + | |||
| + | Anyway, you might have noticed, for example, Garth Nicholson | ||
| + | found a higher incidence of autism in the agricultural areas. This | ||
| + | fellow (video highlights B thuringiensis israeliensis) is sprayed in the | ||
| + | agricultural areas. | ||
| + | |||
| + | If the chronic infection allows the plasmids to spread, these people | ||
| + | will get very ill. | ||
| + | |||
| + | The final thing that I want to show is that the pathogens actually | ||
| + | persist in the brain. | ||
| + | |||
| + | This [slide] is taken from a paper by Rolf Zinkernagle, | ||
| + | lucky to meet at Karolinska, the home of Team Nobel. Rolf gave | ||
| + | the keynote speech there back in May [2006]. And what they | ||
| + | found they' | ||
| + | young age (video highlights A - neonate mice figure upper right | ||
| + | figure), neonatal in fact, with a virus. And this is injected before the | ||
| + | mice have an adaptive immune system. | ||
| + | |||
| + | As you all know, the adaptive immune system in humans and mice | ||
| + | takes some time to kick in (video highlights top time line center, | ||
| + | showing Time after rLCMV/ | ||
| + | coming up to indicate the adaptive immune system has kicked in | ||
| + | after about 7 days. | ||
| + | |||
| + | But when the mice are born, the only thing they have to protect | ||
| + | themselves is the innate immune system. You know, the thing we're | ||
| + | knocking out with ' | ||
| + | |||
| + | Anyway, what Rolf did was, he showed that if they injected this virus | ||
| + | during this period, it remained dormant in the mouse. And later, | ||
| + | when a similar virus was used to challenge the mouse, It killed | ||
| + | them (video highlights upper right dead mouse figure). | ||
| + | |||
| + | Whereas mice that were challenged in adulthood by the same | ||
| + | virus (video highlights lower left time line, far left), injected by the | ||
| + | same pathway were not killed when they were re-challenged, | ||
| + | fact, they survived primarily. | ||
| + | |||
| + | This is a fascinating paper, it is quite detailed with citations there at | ||
| + | the bottom [of the slide]. And Rolf is working on dispelling a myth | ||
| + | of autoimmunity — or response to self — by showing occult | ||
| + | viruses can, in fact, can exist and they can indeed persist in the | ||
| + | brain. Very important when we are trying to understand the | ||
| + | symptoms of our patients. | ||
| + | |||
| + | And here is the slide from Professor Bach, Jean-Francois Bach, | ||
| + | which was presented in Budapest in 2004. Jean-Francois Bach | ||
| + | was the person who proposed the hygiene synthesis. | ||
| + | But what he found was that bacteria, the particular strain of mice | ||
| + | called non-obese diabetic mice (NOD), where typically 60% of | ||
| + | them died (video highlights upper right dark dot line) from | ||
| + | diabetes — type 1 diabetes during their lifetime — that if he | ||
| + | injected them early enough with a mix of common bacterial | ||
| + | proteins, that they survived (video highlights cyan and yellow end | ||
| + | point line). | ||
| + | |||
| + | And the ones that survived best were the ones that got the | ||
| + | bacterial proteins earlier in life than later in life (video highlights | ||
| + | magenta square dotted line lower right). | ||
| + | Again, another fascinating insight into exactly how these diseases | ||
| + | persist and why some people get ill, and other people carry the | ||
| + | bacteria and don't get ill. | ||
| + | |||
| + | Because it is no secret that the NIH/NHLBI did a study in 2001 | ||
| + | where they tested with PCR, they tested the blood of controls. No, | ||
| + | they didn't use PCR, they cultured the L-form using Wayne State | ||
| + | Lyda Mattman' | ||
| + | were carrying L-forms in the blood. Supposedly a sterile | ||
| + | compartment. | ||
| + | |||
| + | This has since been confirmed by the Relman Lab, Dave Relman | ||
| + | up at Stanford published a paper in the last year, where he too has | ||
| + | noted that 60-80% of the population are carrying around bacterial | ||
| + | RNA in their blood. It should not be there. Many of them, most of | ||
| + | them in fact, are not ill or certainly not diagnosably ill. Some | ||
| + | however, regress to really serious illness. It all depends on the DNA | ||
| + | mix and how the mutations progress in life. | ||
| + | |||
| + | |||
| + | So just a few quick final thoughts that my colleagues at FDA felt I | ||
| + | had to put in because I am talking to clinicians here, [are] just the | ||
| + | simple stuff again. | ||
| + | |||
| + | Final thoughts, if you are thinking if your patient might in fact be | ||
| + | suffering from Th1 diseases, then the therapeutic probe is really | ||
| + | the gold standard. That's because it is greater than 95% response | ||
| + | rate. Most of the patients will immediately feel immunopathology. | ||
| + | They' | ||
| + | antibiotics. At that point you know that you are killing bugs. You | ||
| + | know that these people are responding. | ||
| + | |||
| + | The only thing I would say is 25-D levels above about 20ng/ml | ||
| + | you will be getting immuno-suppression there and it will be | ||
| + | suppressing the therapeutic probe. So you need to be somewhat | ||
| + | careful about the 25-D level before initiating a therapeutic probe. | ||
| + | Hypotension is not a concern, even though we are using an | ||
| + | angiotensin-receptor blocker. These are the graphs from the FDA | ||
| + | describing insert, the package insert [see slide figure]. As you can | ||
| + | see, the maximum drop is about 12 millimeters of mercury [12mm | ||
| + | Hg], and that value is independent of dose. You can see the dose | ||
| + | along the bottom here the response tops at 40mg. It is not a very | ||
| + | good hypotensive. Benicar is not a very good hypotensive. Luckily, | ||
| + | it does other things as well like protect the kidneys, and protect the | ||
| + | eyes and all the other things that you are reading about in the | ||
| + | clinical literature right now. | ||
| + | |||
| + | Hypotension is not a concern. | ||
| + | |||
| + | Dizziness. When the patients get dizziness, especially in the first | ||
| + | month, it's usually a sign of the disease process. It is not | ||
| + | hypotension. It's actually better to increase the Benicar to give | ||
| + | them a better blockade than to back off the Benicar. | ||
| + | There is no way you can start with a low dose and work up. You've | ||
| + | got to have those receptors being blocked, all the receptors being | ||
| + | blocked, or it doesn' | ||
| + | immunopathology with only a low dose. That means the patient | ||
| + | will get, " | ||
| + | dose of Benicar, but they won't get the palliative effects, they won't | ||
| + | get the renal-protective effects, until the dose goes up. | ||
| + | So it is very important to give them the correct dose so they are | ||
| + | actually going to make it through the therapy and kill those bugs | ||
| + | off. | ||
| + | |||
| + | The only thing I didn't mention was how long it would take: three | ||
| + | to five years for the seriously-ill patients to totally get their lives | ||
| + | back. Most of them are happy with some form of recovery. They | ||
| + | see the light at the end of the tunnel after about six months. Very | ||
| + | few have not seen the light by twelve months but actually, they are | ||
| + | symptom free or say they are symptom free at about two years. But | ||
| + | all that means is they are getting along from day to day very nicely | ||
| + | and much better than they were before. There is still a lot of | ||
| + | disease present, they are still getting a lot of reaction to the | ||
| + | antibiotics. | ||
| + | |||
| + | It takes about another two years to where they can just guzzle the | ||
| + | antibiotics like candy. At that point, the bacterial load is low | ||
| + | enough for them to pronounce recovery. | ||
| + | |||
| + | Thank you. | ||
