Asguidedintent@gmail.com or asguided.ca Craig is 37 years old and grew up on a farm in South Dakota. He always had big dreams and high anxiety. He was brought up in a stable family, his parents are still together and his mother and father both had anxiety and he now realizes how much that imprinted on him. He dropped out of law school to be a comedian at age 23 and did some shows, but by then he was 5 years into a pretty heavy alcohol addiction to cope with panic attacks. He worked odd jobs, until he was 28 years old, at which point he had a mental breakdown and quit alcohol. He always had aches and pains, injuries that lasted all summer, foot issues, etc. He never took care of the mental aspect after getting sober, and then the stress of 2020 spring at age 34, the pandemic kicked things into overdrive, suddenly his leg and S.I. joint were constantly inflamed to the point of not sleeping, not being able to walk. Went to dozens of doctors, orthopaedics, brain and spine doctors, and finally, he was the one who suggested an HLA-B27 test. Then finally after waiting..in Feb 2022 his rheumatologist told him biologics are the answer since he had tried NSAIDs for so long, and that he would have this for life. He didn't accept this, and that's when he started searching (meat-only diet, CBD oil, and seed gut protocols, stretching, special hip apparatuses for relieving muscle tension, and massages. For his career, he does freelance drone photography, auctioneering, and cattle farming with his dad.

Notre 1er invité est Kepa pour la sortie de son 2ème album Divine Morphine (Éditions Miliani). C'est toujours la même chanson, celle qui tient en un mot. Cinq lettres, trois consonnes et deux voyelles. Un B, un L, un U, un E et la marque du pluriel au bout. Un mot international, qui désigne à la fois une musique, un état émotionnel et vaguement une couleur. Vous l'avez, là ? Chut… Il ne faut plus l'écrire, ni le nommer, pour ne pas tomber dans ses clichés, ni y emmener les auditeurs du deuxième album de Kepa. Kepa ne veut plus en entendre parler, pourtant il l'a. Dans sa guitare en métal qui, entre de bonnes mains, ressemble à une lampe d'Aladin, à une épée mythologique. Dans son harmonica, cet instrument qui fait trembler le cerveau quand on en joue avec le cœur. Dans sa vie de tous les jours et même de tous les hiers. Au fond de ses tripes, comme un frisson qui remonte jusqu'à ses cordes vocales, un super pouvoir dont il faut aussi avoir peur. Dans ses gênes, son corps endolori, son sang altéré. Dans le titre de ce nouvel album, Divine Morphine. Le premier, sorti il y a trois ans, s'appelait Doctor, Do Something. Un début de concept, toujours la même chanson, comme une affection longue durée. Kepa l'a attrapé comme une maladie. En 2013, Kepa s'appelait Bastien Duverdier et il vivait la vie de skater professionnel, humain augmenté capable de voyager loin et de s'envoler sur une planche à roulettes. Quant tout à coup, il s'est senti devenir vieux. Rongé par une maladie auto-immune qui a bouleversé sa vie, les chiens de l'enfer à ses trousses, qui ne le lâcheront jamais. Il a trouvé une planche de salut, sans roulettes mais avec des cordes, dans la musique, pratiquée sur sa guitare en métal et de préférence sur un ou deux accords qui tournent, à la recherche d'une transe intérieure, d'une vibration musico-thérapeutique, d'un rite auto-chamanique. Bastien est devenu musicien, sortant donc en 2018 Doctor, Do Something, premier album réalisé avec Taylor Kirk du groupe canadien Timber Timbre. L'album a été très bien accueilli, et des centaines de concerts ont fait connaître Kepa, son humour, sa musique et ses jolies chemises.   Mais, malgré tout le bien qu'on a pensé de Doctor, Do Something, on peut l'affirmer sans forfanterie : Divine Morphine est mille fois mieux. Doctor, Do Something était une carte de visite. Divine Morphine est le récit d'une expédition au fond de soi, d'un voyage au bout de l'enfermement. Personne ne t'entendra crier. Il a fait ce disque pour chercher à comprendre, dompter et raconter cette maladie qui l'a chamboulé jusqu'à l'implosion, à l'orée de la folie. «Du plomb dans l'Eldorado», chante-t-il en duo avec Sarah McCoy sur l'incroyable dark-pop song Eldorado, un vrai tube du nouveau monde. Du plomb dans l'Eldorado, c'est un peu ce que tout le monde ressent depuis l'année 2020, non ? Le calvaire des uns est la Covid-19, le sien s'appelle HLA-B27, pour human leucocyte antigen. Personne ne peut le vivre à sa place, mais tout le monde peut ressentir et apprécier comment il s'est soigné avec Divine Morphine. Le premier morceau est un peu son All Aboard (Muddy Waters) à lui. Un solo d'harmonica basse façon train song, qui aurait eu sa place sur Doctor, Do Something, mais qui d'un coup tourbillonne, se dérègle et annonce la suite. Le train vient de dérailler et d'entrer dans une autre dimension, celle du vertige opiacé, de la perte de contrôle, de la musique qui rêve et dérive… Une chanson va sonner comme la bande-son d'un western où Kepa fait un duel avec lui-même (Dog Days). Une autre emmène les vieux Bukka White et Alan Vega danser dans un club de Détroit pendant un tremblement de terre (Wet Dream). Le temps de deux reprises, Kepa s'agenouille sans se prosterner devant des totems intimes : Hard Time Killin Floor Blues de Skip James (avec Rodolphe Burger), et Sodade de Cesaria Evora dans une version hallucinée, où l'on voit l'océan geler autour des îles du Cap-Vert.   Six pieds sous terre reste sous les tropiques le temps d'une murder ballad. La chanson Divine Morphine est presque badine, indolente, ritournelle dans un état second. L'instrumental Messe HLA-B27 montre les progrès guitaristiques fulgurants de Kepa, affranchi des exercices de styles, devenu son propre maître. Sa voix aussi a changé, il la pousse vers la plainte dans des aigus hululants. Il joue différents instruments, des claviers comme des stalactites, la trompette et d'autres choses avec sa bouche, des bruitages d'origine non identifiée. Il est l'homme-orchestre du Titanic, au final seul survivant du naufrage, puis échoué sur une île déserte – le dernier morceau, Merle, ressemble à la prière païenne d'un Robinson en lévitation. L'album est maintenant terminé. Personne n'en sortira indemne. Et tout le monde n'aura qu'une envie : y retourner. Stéphane Deschamps. Titres interprétés - Divine Morphine, Live RFI - Sodade, extrait de l'album Divine Morphine - Eldorado, Live RFI - Hard Time Killing Floor, extrait de l'album Divine Morphine. Puis nous recevons Jawhar pour la sortie de l'album Tasweerah (62TV/PIAS).   Tasweerah est le quatrième album du singer / songwriter tunisien Jawhar. Tasweerah veut dire en tunisien à la fois : portrait, image, mais aussi : projection de l'esprit… L'album est une série d'arrêts sur image, de portraits plus ou moins personnels. Les chansons sont, chacune à leur manière, des tentatives vers un portrait universel de l'artiste. Elles questionnent sa place et celle de l'imaginaire dans la société, posent «la création et la quête de la beauté» au centre de l'album. Volontairement brut et sans artifice, Tasweerah nous replonge dans la folk / pop claire-obscure de Jawhar, proclamé dans la catégorie Arabic Dream Pop. Né d'une mère professeure de Littérature arabe, éprise de musique et de poésie, et d'un père qui se consacre au théâtre puis à la politique culturelle, Jawhar grandit dans la banlieue au sud de Tunis, à Radès. Très tôt, il est fasciné par une certaine culture populaire, par la force de ses images et de ses expressions verbales, musicales et gestuelles. Quand il part à l'âge de vingt ans étudier l'anglais à Lille, c'est plutôt la poésie abstraite qui l'attire, celle de William Blake et d'Emily Dickinson… En plus d'un amour grandissant pour un certain Nick Drake qui le liera de manière irrévocable à sa folk impressionniste.

Inflammation can occur in any part of the body and the eye is no exception. In this episode, we discuss uveitis and scleritis, two specific inflammatory conditions of the eye. Uveitis, one of the major causes of vision loss, is an intraocular inflammatory condition that can be broken up into three categories: infectious, non-infectious, and traumatic. It can further be classified by where the inflammation occurs in the eye: anterior (front part - iris), intermediate (middle part – ciliary body), posterior (back part – choroid), and panuveitis (entire eye).Infectious uveitis can be caused by bacteria, viruses, fungi, and parasites in the eye or by a systemic infection like herpes, tuberculosis, syphilis, toxoplasmosis, or Lyme disease. Noninfectious uveitis, the most common type, can be caused by autoimmune conditions like rheumatoid arthritis, lupus, sarcoidosis, Reiter syndrome, ankylosing spondylitis, Behcet's disease, psoriatic arthritis, and inflammatory bowel disease. The most common reason for uveitis is called idiopathic – no reason can be found. Symptoms of uveitis will vary according to its location in the eye. Anterior uveitis, also called iritis, can cause ocular pain, photophobia (light sensitivity), red eye, and decreased vision. Uveitis in the back of the eye mainly causes vision loss but usually does not cause pain.After a thorough eye examination, a lab work-up should be performed especially after the second recurrent episode or if the first episode affects both eyes. Ruling out an infectious cause can be done in the office. Bloodwork to rule out some of the autoimmune diseases is the next step. Sometimes a chest x-ray may be necessary to help rule out TB or sarcoidosis.Treatment of infectious uveitis is directed at the pathogen causing the infection. This may involve a combination of topical antibiotics or anti-virals and systemic medications. Steroids are the mainstay of treatment of non-infectious uveitis. Most anterior uveitis is treatable with topical steroid eye drops. Intermediate and posterior uveitis is mainly treated with oral steroids and steroid injections around or in the eye. For patients with chronic or recurrent uveitis, immunomodulatory therapies may be necessary. Some of these medications may include methotrexate, Cellsept, Humira, and Remicade.Scleritis is an inflammatory condition of the outer coating of the eye (sclera). Symptoms include severe eye pain, red eye, and sometimes a decrease in vision. If the back part of the eyewall is inflamed, the eye may not appear red. An ultrasound of the eye may be necessary to properly diagnose this condition. Some of the causes of scleritis include rheumatoid arthritis, HLA-B27-related diseases, and gout. Oral and injectable steroids are the primary treatments for this condition. Sometimes immunomodulatory therapies are also needed to control the inflammation. Here are some more links to learn more about inflammation in the eye.Uveitis.orgPreventblindness.org/uveitis/Scleritis To find out more about Dr. Lou Chorich and his practice, go to Midwest Retina's website.This is intended for informational and educational purposes only, and nothing in this podcast/blog is to be considered as recommending or rendering medical advice or treatment to a specific patient. Please consult your eye care specialist for proper diagnosis and treatment of any eye conditions that you may have.

In this week's episode of the Spine & Nerve podcast Dr. Nicolas Karvelas and Dr. Brian Joves review a common cause of low back pain, sacroiliac joint (SI) pain. The SI joint is a large complex joint that involves the iliac bone and sacrum. The SI joint is a critical component of the connection between the spine and lower limbs, and one of the primary functions of the SI joint is stability. Chronic SI joint pain is a relatively common cause of low back pain with epidemiologic studies demonstrating that SI joint pain significantly contributes to 10-38% of cases of chronic low back pain. Risk factors for SI joint pain include: leg length discrepancy, gait abnormality, scoliosis, spinal fusion, hip pathology, pregnancy, high force/velocity injury, seronegative HLA-B27 spondyloarthropathies, repetitive shear stress injuries in athletes. The common clinical presentation for SI joint pain includes aching pain below the belt line, with radiating/referred pain to gluteal/buttock region, groin, posterior leg, and less commonly thigh. This pain is often worsened with prolonged sitting, sleeping positions, movement. Physical exam results supportive of a diagnosis of SI joint pain include at least 3 positive tests, with at least one of these tests being thigh thrust or compression test. The 5 recommended provocative maneuvers include: 1) Distraction test 2) thigh thrust test 3) FABERE 4) Compression test 5) Gaenslen's maneuver. A recent expert opinion article titled A Review and Algorithm in the Diagnosis and Treatment of Sacroiliac Joint Pain, works to clarify the approach to diagnosis and treatment of SI joint pain. This review article highlights the importance of optimizing the diagnosis as soon as possible to guide treatment, and image guided injection remains the gold standard for the diagnosis of SI joint pain. Listen as the doctors review SI joint pain, and discuss the algorithm presented in the recent expert opinion review article.

This week, Tiffany and Patrice discuss the importance of biomarkers. Do biomarkers hold the key to understanding disease severity and predicting disease onset? In this episode, we talk about biomarkers, or a measurable indicator present in the blood or tissues, and how their presence in our bodies can predict disease severity and guide treatment development. Furthermore, evidence that identifying biomarkers early - BEFORE DISEASE ONSET - could actually prevent a person from developing the disease.  Now, there is still the environmental plus genetic factors to consider, but the findings are promising.  While the research focuses on Rheumatoid Arthritis (RA), showing how those who are sero-positive - in addition to having other genetic biomarkers - have a higher likelihood of developing severe disease and bone erosion,  Tiffany points out this is similar to Axial Spondyloarthritis, where many of those with non-radiographic disease do not have the biologic HLA-B27 gene that is present in most with radiographic evidence.   The bottom line is that learning about biomarkers can help patients navigate their own healthcare journey, but also could possibly prevent their loved ones from developing these diseases in the future.  Now, if you are a patient or parent of a juvenile patient - are you ready to join the conversation? It's your turn to pull up a seat! Join Tiffany and Patrice to continue this conversation inside our new, coordinating AiArthritis Voices ONLINE COMMUNITY - where patients unite with others around the world to talk, learn, and connect.  JOIN TODAY! Other stakeholders - are you a doctor, nurse, researcher, industry representative, or other health services person who wants to join us "at the table", too?  Then message your comments or questions about this show to podcast@aiarthritis.org OR message us on any of our social media accounts at @IFAiArthritis.    AiArthritis Voices 360 is the official talk show for the International Foundation for Autoimmune & Autoinflammatory Arthritis (AiArthritis).

Hello, and welcome to today's episode of The Ankylosing Spondylitis Podcast. I'm really glad that you could join me today because we're going to have fun today, we're going to be combining some of my favorite subjects history, modern medicine, and a little bit of speculation mixed in. So stay tuned. This one should be a lot of fun.  I've partnered up with a couple of really good companies. One is Joy Organics and you can find the link in the show notes. If you use that link. It doesn't change the price of anything for you. It just reverts a little commission back to the show to help keep the show going and hopefully growing and Joy Organics make some of the best organic based CBD products that you'll find whether it be tinctures pills that I take the soft gel tablets, I really like those and also a drink mix that I just put it into a jar water, shake up the water and drink it and it adds a bit of CBD through the day as I drink that water. So it's a great way to help level it out through the day as you're drinking that. So they have all sorts of products, lotions. So check out the link to go to Joy Organics. They're 100% organic hemp grown in the United States is where they derive all their CBD oil from so you can't go wrong going to Joy Organics link in the shownotes. The other one is new. Now, if you have kids cover their ears Foria is an intimacy lotion that is really fantastic and it works. I don't even know how to describe it beyond just that it works. It has a CBD base to it, and you apply it and it helps. So again, go to the show notes where you can access the link for Foria and then go and read about it and see if that fits something that might be of interest to you. Again, no price increases but it does pay a commission back to the show which helps to keep the show going and growing. Thank you.  So in today's episode by the title, you saw the word Neanderthal and you go, “What does that have to do with ankylosing spondylitis at all?” Well, I wondered the same thing. And then I was directed towards a few interesting articles and I started reading them and it really was a very interesting hypothesis. So about 30,000 years ago, give or take a few thousand years. What we would know as the modern homosapien came wandering out of the continent of Africa as they were migrating north. And as they got into the colder climates, they walked right into and head on confrontations with an ancestor of theirs that was already living there. But that hadn't changed in the hundreds of thousands of years. The Neanderthal was they got there, what you would expect took place, conflict, fighting, death as one type of species tried to basically conquer the other. Which one was going to win? Well, it ended up obviously being humans, you know,Homo sapiens. But did we walk away with a gift or maybe a curse From Neanderthals? Well, let's look at that. It's an interesting hypothesis or interesting series of debates that had gone on around this. So I was directed to a website called Everyday Battle, where there was an article entitled How a weird fetish among our ancestors led to Ankylosing Spondylitis. And so I started to delve into this article and found it to be really interesting, and I'll have a link down below what the studies are showing where now this is from some information that came out in the 2013, 2012 somewhere back in that area. But it was based upon looking at the DNA of Neanderthals and (modern day)humans and what they found in that and what may have carried over to us as modern humans. Studies suggest that Neanderthal genetics may be responsible for autoimmune diseases in modern humans. The author discusses a documentary called Decoding Neanderthals and in that documentary, they talked about discovering in the ancient DNA of these Neanderthals, the HLA alleles, and one particular HLA, HLA-B27 is the main genetic marker that's used to diagnose Ankylosing Spondylitis. It's found in 95% of the people with AS. Now, Support this podcast

This last one I sent out had pictures of Bandit in it, my service dog and training so you never know what I'm going to include in there.  Now on to today's show, I see a lot of questions asked online every day about Ankylosing Spondylitis and these questions ranged from real basic, I've just been diagnosed, what do I expect? What should I expect? Should I take medication? Can I cure it? To very detailed questions specifically in relation to is this part of Ankylosing Spondylitis or not? So I put together these nine questions and some answers to them that hopefully this will help you as you start off your journey with Ankylosing Spondylitis.  Number one is Ankylosing Spondylitis an autoimmune disease? Ankylosing Spondylitis is both an autoimmune type of arthritis and a chronic inflammatory disease. An autoimmune disease develops when your body attacks its own healthy tissues. Ankylosing Spondylitis is also an inflammatory condition that involves inflamed or swollen joints. It often affects joints and bones in the spine, lower back spinal bones confused together over time, and this is what is known as bamboo spine and, and how the name developed.  Number two, what exactly is Ankylosing Spondylitis? Ankylosing Spondylitis is a type of inflammatory arthritis that affects the spine and the sacroiliac joints in the pelvis. Like many types of arthritis, Ankylosing Spondylitis can cause pain and swelling in the joints. This condition affects the bones of the spine, the vertebrae, and joints in the lower back. It also causes swelling were the tendons and ligaments attached to the bones in your spine. Your doctor might call this and Enthisitis pain and discomfort from Ankylosing Spondylitis can lead to symptoms in other joints such as shoulders, hips, you know, basically, if there's bones that come together, or there's muscles or ligaments AS can affect those areas.  Number three, how is Ankylosing Spondylitis diagnosed? The doctor will likely start by asking about your symptoms and family history of AS. An exam can reveal symptoms like pain, tenderness and stiffness of your spine. The doctor then might send you for an X ray or MRI, or maybe even both, though generally not on the same day. Both tests can show damage to bones and soft tissues in your spine. An MRI creates more detailed images, and it can show damage earlier in the disease than an X ray can. Another way to diagnose this condition is with a blood test for the HLA-B27 gene. Now, some people don't have this gene, but have Ankylosing Spondylitis and not everybody that's positive with the HLA-B27 gene will have Ankylosing Spondylitis.

Jayson: Michael, welcome to this episode of the Ankylosing Spondylitis podcast. And based upon the introduction and what we're going to cover today, I may have to change that name at some point down the road. Welcome to the show. Michael Thank you, Jayson. And thank you for having me. And yes, there's certainly time to change terminology around our disease. Jayson: Well, I was diagnosed 35 years ago, things tend to change slowly. So hopefully, I'll get around to figuring that out and what I want to do and how we structure it, but you know, you and I met through a forum on Facebook that deals with ankylosing spondylitis and the whole disease structure itself. You've made multiple posts that have been met differently with people's reactions on why the correct terminology might not be calling the disease itself ankylosing spondylitis, but maybe better off calling it Axial Spondyloarthritis. Tell me a little bit about that. Michael: Well, I can I understand why people are married to the next Ankylosing Spondylitis because like you that's what I was diagnosed with. And after my disease onset 40 years ago, but times change the technology changes, and also the name Ankylosing Spondylitis was never a universally used name, still isn't. In many parts of Europe, especially German speaking countries, the disease is referred to as Mobis Bechterew. In Russia, for example, it's named after Vladimir Bekhterev who was a Russian doctor who documented some of the symptoms of Ankylosing Spondylitis, but it's also been called Marie-Strumpell disease as well after two researchers who described the disease but what's more important, from our point of view is that Axial Spondyloarthritis is very difficult to diagnose. Originally, it was diagnosed by X ray radio graphically. So back in 1973, people recognized that there was a very common association with the gene HLA-B27 and spondyloarthritis. And looking into that further, they started seeing that people with Axial Spondyloarthritis or then called Ankylosing Spondylitis had this radiographic stage. And that was used as a diagnostic tool. There are no diagnostic criteria for this disease, but there are lots of different classifications. So, if you had radiographic sacral sacral le itis, and you displayed some other spondyloarthritis symptoms like family history or morning stiffness, etc. You were diagnosed with Ankylosing Spondylitis, then MRI came into being in the 1970s By the 1980s it was out there in the general hospital population and in general use and people who could read MRIs started noticing that if they were taking an MRI of the sacroiliac joint, they could see sacroillitis. But was this the same as the sacroillitis evident by X ray in Ankylosing Spondylitis? And there was a long debate about that. And that debate really wasn't resolved until the last year or two. So it's now understood that what we call Axial Spondyloarthritis is a continuum of disease from what had been called non-radiographic axial spondyloarthritis through to radiographic axial spondyloarthritis. So it's all recognized as one disease. And the important thing about that is that to exclude people, from patient organizations from help and support from the treatments available for Ankylosing Spondylitis, because they have non-radiographic axial spondylitis writers is extremely unfair. The disease burden is the same. Somebody with non-radiographic axial spa has exactly the same symptoms, the same pain, the same stiffness, the same mental issues as somebody who they ankylosing spondylitis. There's a further important part and that is that we know from a lot of evidence that the earlier the treatment, the better the outcome for the patient. So if you're waiting 6,7,8,9,10 years for diagnosis, and you don't get onto a treatment plan, until you're sort of seven or eight years into your disease progress. That's pretty serious, because by then you could have disfigurement, you could have kyphosis, you could have fusion, Support this podcast

Hello, and welcome to this week's episode of The Ankylosing Spondylitis Podcast. I hope this show finds everybody doing well. In today's show, I want to look at the relationship between your microbiome and Ankylosing Spondylitis. The reason for this came about from looking at a few items online and in some of the forums on Facebook. I was seeing one particular thread I believe an example that there was a number of people giving definitive, this is how I got Ankylosing Spondylitis. This caused my Ankylosing Spondylitis and that might have triggered a flare that brought the Ankylosing Spondylitis to your attention, or made you notice some of the symptoms that made you look further into what was causing them. But at this time, there really is nothing that I've ever found that says the doctors can pinpoint to this one exact reason as to why you got Ankylosing Spondylitis. No, there are some different contributing factors and there are some items that again, may have happened that triggered the domino to happen and and Ankylosing Spondylitis to finally come to life. There's nothing that at this time, they know, this is what exactly triggered anybody's Ankylosing Spondylitis. And that's what's really frustrating for a lot of us with the disease, is that we all present differently. We all get different symptoms, different reactions to medications. And if you listen to my episode a few back with Dr. Fox (Episode 42), he said there are some tests coming down the road that could help to better pinpoint which biologics you'll respond to better versus others. And that way, it's not such a guessing game like there is now with biologics where it's like, well take Enbrel if it doesn't work take Humira, if it doesn't work, take this one. It might take you four, five, or six until you find one that works. And if they have a way to narrow that down to one or two, that in of itself would be a great start to treating Ankylosing Spondylitis. The real big breakthrough is going to come when they can figure out what underlying symptoms make you susceptible to having it at some point in the future. One of those things is the gene, HLA-B27. Many people have that gene and it doesn't mean that if you have it, you will develop Ankylosing Spondylitis. Because there's people that don't have it, that develop Ankylosing Spondylitis. So it's just one of those factors to look at. So I happened to be looking around on ankylosingspondylitis.net, which is a fantastic resource, that if you're not using it you should be. People with Ankylosing Spondylitis write many of the articles and the editorial team writes many. I encourage you to head over, it's just a fantastic resource. And it got me thinking, I found this article, which is where I tell the show about the relationship between the microbiome and Ankylosing Spondylitis. And I thought it was really interesting. I've also saw a lot of people coming onto the forum saying, I'm brand new. I need to learn. Where do I start? What do I do? So this is something that might be a good spot to start to think about as you try to develop your game plan for dealing with Ankylosing Spondylitis. What we know is that about 40 years ago, researchers found out that people with HLA-B27 are much more likely to get Ankylosing Spondylitis.  HLA-B27 is a genetic trait associated with the immune system and the inflammatory conditions like Ankylosing Spondylitis. Well, scientists still don't know why. There is connection between Ankylosing Spondylitis and HLA-B27. They continue to study that relationship, and the potential link to help find further treatments for the condition of, of ALS and, and potentially other items. So, one of the areas that is being researched and I want to look at some more, and this is the microbiome. What is the microbiome? Well, all of us have trillions of bacteria living, you know, in us and on us on our bodies, you know, in our bodies, and this collection of bacteria is called your microbiome.

This week, join your host, Tiffany, as she and co-host Charis Hill discuss the evolution of the term Ankylosing Spondylitis into the new umbrella term:  Axial Spondyloarthritis. What does this new term mean? How will it impact treatment options or the patient experience? Does it even matter what your diagnosis is if the treatments for AiArthritis are all basically the same? Listen in as they talk about these and other issues surrounding finding the right diagnosis.

5 Things I'm Tired of Hearing About Ankylosing Spondylitis

Hello, and welcome to The Ankylosing Spondylitis Podcast. Can you believe that this is almost the end of 2019? Man this year has just flown by. It's been a really, really interesting year for me from the great highs with this show, the great numbers that have come in and the positive feedback I've got from everybody about liking the show, to going from highs like that to dealing with the passing of my father in August and the whole dynamic that created for me. I know I'm grateful for the almost 75 years that he was around and he was here for me. So that was fantastic, but I'm not going to lie. It still stinks to you know, I want to call him. Even though he didn't have Ankylosing Spondylitis, he and my stepmother listen to all these episodes, and were two of my biggest cheerleaders for these episodes. It's fantastic to know the years that I had with him.  So with that, on to the show. Now for the Question of the Week, this is going to be a little bit different because I happened to be online and I saw a posting from a fellow AS person in Australia named Tieran Brownlee. He posted an article, now I'm going to butcher this so up front, I apologize, but it is from the xinhua.net, and I'll have a link to it. So don't try to write any this down. It was dated December 7, 2019 and it says Scientists uncover potential nuclear of “bamboo spine”, otherwise known as Ankylosing Spondylitis. So here in Taipei, team of scientists from Taiwan uncovered how the human gene HLA-B27, triggered Ankylosing Spondylitis, which might lead to symptoms of bamboo spine, leading them to find a promising new cure for the disease. Can you believe that? The words Ankylosing Spondylitis and potential promising cure don't even seem like they should be in the same paragraph. So a collaborated research team led by a Dr. Lin Kuo-i with Genomics Research Center of the Academia Sinica in Taiwan, and they found the gene HLA-B27, triggers a miscoded protein response, and then a series of abnormal signal transduction, which eventually causes an isozyme called “tissue-nonspecific alkaline phosphatase” (TNAP) to be highly activated. The elevated tip was demonstrated to be the cause of bone like cell formation around a person's spine, the research team sent a press release. So that's the extent of the article I'm going to read. There will be a link in the show notes to it and I would encourage everybody to read it. It really caught my eye because farther down you'll see that researchers have found that two existing medicines that are already out there to treat items may be possible cure for Ankylosing Spondylitis. So they may have stumbled across something. As they look at this, we don't know. It's from China. It's not anything that's apparently maybe cleared through the FDA. So it could be years and years and decades away. We don't know. But it's definitely an interesting article to read. So I hope you all go out and read that article, and I'll have a link to it.  Now, on to the main topic of today, this week, as I was looking through some ideas about what to do for the show, I happened to be going through one of the Ankylosing Spondylitis forums online and I saw some people talking about you know, I hate it when somebody says this, right I hate it when somebody says that in relation to Oh, my back is bad or Yeah, I had AS but I cured it. You know, people say the craziest things to you. I generally like to think the best of people in that they aren't trying to be mean or be off putting their generally trying to be helpful. They just realize they're not being helpful. They're actually being a pain in the rear sometimes.  So I have to come across this article by Ricky white. That name sounds familiar. I did an interview with Ricky few months back for the show. He has Ankylosing Spondylitis. And the last episode, we talked about his book called Taking Charge - Making your Healthcare Appointments Work for You. So the article that I... Support this podcast

Hello, and welcome to The Ankylosing Spondylitis Podcast. Well, this is the month of November and I hope everybody's doing well. First I want to take a minute to talk about the show itself. I cannot thank everybody enough for making October just an amazing month for the show. The download numbers were through the roof and the feedback I got on the episodes was fantastic. So I really appreciate that and we added in a number of new countries that have access to show Let's get right into the show for the Question of the Week, I saw several people asking the same question online and it is can Ankylosing Spondylitis be inherited? Is it an inheritable disease you know, from one family member to the next generation to generation, in essence, it can run in families. In one of those markers, they used to look at it as the HLA- B27 gene. Now having this gene doesn't mean that you will get Ankylosing Spondylitis, but it is one of those markers that they look for. I found this kind of interesting in that research has shown that more than nine out of 10 people with AS carry the HLA-B27 gene, that's pretty amazing. It's almost 100% of everybody has it having this gene does not necessarily mean you'll develop as, as I said, it's estimated eight in every 100 people in the general population have the HLA-B27 gene, but most do not have AS so if you have it, you may end up getting AS but it doesn't mean you will. It also shows that's one of things you can look at it and family members and this particular person in the Question of the Week, they were wondering if they should have some family members tested for it because they and the other sibling had it. So I kind of replied back that it's not going to hurt anything. It never hurts to know if that gene is present because it could go along to explaining some future medical conditions if they run into AS it's also something to know that as we said as can run in families that gene can be inherited from familymembers to family member and if you have AS and test show you carry the HLA-B27 gene and their is a one in two chance that you could pass on the gene to any children you have is estimated that between five to 20% of children with this gene will then go out and develop AS that's still quite a wide variants of it. I have three kids they were all tested for the gene and if I remember right to came back with it, one didn't maybe all three had it. I don't remember exactly what it was, but they were tested and I believe my two older ones did have the gene one is showing some effects. I don't know if she'll come to grips with it. And hope you know, personally, I hope nothing ever develops of it. The other one is not nor is the youngest one. With that said, let's move on to today's topic of discussion. The Question of the Week done, let's look at this week's topic. You know, when I was diagnosed with Ankylosing Spondylitis, I was told a couple of things. Now,granted, you know, this was 35 years ago, so a lots changed. But when I was diagnosed, I was told this is primarily a man's disease, you'll rarely if ever see it in women. And it's primarily disease people of Mediterranean descent. What we found out is that is obviously not the case. So we know that today all these advances have been done in the research for Ankylosing Spondylitis that in fact, women get it probably just as much as men. I found this really cool article and it talked about different things dealing with a woman's diagnosis with Ankylosing Spondylitis. Again, as we've all heard, and been told women don't get it, but we know that that is incorrect. And I've had to do is look through the boards on Facebook, you'll see that there's just a ton of women dealing with this condition. So as we know, Ankylosing Spondylitis is an inflammatory form of arthritis that we get that starts in our SI joints or spine moves up the spine and then or can affect your ribs, your shoulders, your neck, move down affect your knees.

HIV-1 is a chimpanzee virus which was transmitted to humans by several zoonotic events resulting in infection with HIV-1 groups M P, and in parallel transmission events from sooty mangabey monkey viruses leading to infections with HIV-2 groups A H. Both viruses have circulated in the human population for about 80 years. In the infected patient, HIV mutates, and by elimination of some of the viruses by the action of the immune system individual quasispecies are formed. Along with the selection of the fittest viruses, mutation and recombination after superinfection with HIV from different groups or subtypes have resulted in the diversity of their patterns of geographic distribution. Despite the high variability observed, some essential parts of the HIV genome are highly conserved. Viral diversity is further facilitated in some parts of the HIV genome by drug selection pressure and may also be enhanced by different genetic factors, including HLA in patients from different regions of the world. Viral and human genetic factors influence pathogenesis. Viral genetic factors are proteins such as Tat, Vif and Rev. Human genetic factors associated with a better clinical outcome are proteins such as APOBEC, langerin, tetherin and chemokine receptor 5 (CCR5) and HLA B27, B57, DRB1{*}1303, KIR and PARD3B.

In der vorliegenden Arbeit wurden therapeutische und immunmodulatorische Effekte einer TNF-Blockade bei Patienten mit aktiver Spondylitis ankylosans untersucht. Hierzu wurde an 10 Patienten während einer 60wöchigen Infliximabtherapie eine Evaluation von Therapiewirksamkeit und -sicherheit, sowie eine durchflusszytometrische Analyse der HLA-Oberflächenexpression auf Lymphozyten vorgenommen. Von 8 Patienten wurde die Therapie ohne ernste Nebenwirkungen gut vertragen und führte zur raschen und dauerhaften Verbesserung der klinischen, laborchemischen und radiologischen Verlaufsparameter. Ein Patient entwickelte nach initialer Wirksamkeit ein sekundäres Therapieversagen, bei einem weiteren Patienten wurde die Therapie unter dem Verdacht eines medikamentös induzierten Lupus-Syndroms abgebrochen. Gegen Mitte des Behandlungszeitraumes konnte ein am deutlichsten auf den B-Lymphozyten ausgeprägter Anstieg der HLA-B27- und MHC-Klasse-I-Expression beobachtet werden. Die Expressionszunahme ist möglicherweise Ausdruck immunmodulatorischer Effekte, die mit der langfristigen Therapiewirksamkeit assoziiert sind. Für die Zunahme der Oberflächenexpression kommen folgende Mechanismen in Frage: 1. eine vermehrte intravasale Kompartimentierung primär hoch exprimierender Zellen oder 2. eine durch die TNF-Suppression induzierte Hochregulation einer zuvor niedrigeren HLA-B27-Oberflächenexpression. Angesichts unserer Ergebnisse und der aktuell in der Literatur verfügbaren Daten halten wir letzteren Mechanismus für wahrscheinlicher. Innerhalb dieses Erklärungsmodells ist die bei Therapiebeginn niedrigere HLA-B27-Expression bedingt durch die Expression einer verminderten Anzahl von HLA-B27-Molekülen oder aberranter β2m-freier Varianten, die durch die von uns verwendeten konformationsabhängigen Antikörpern nicht detektierbar sind. Unter Hemmung des TNF-Einflusses kommt es schließlich zur schrittweisen Wiederherstellung der physiologischen Prozessierung trimolekularer HLA-B27-Oberflächenantigene mit konsekutiv vermehrter AK-Bindung. Eine verminderte oder aberrante HLA-B27-Expression ist möglicherweise mit immunmodulatorischen Effekten im Sinne einer erhöhten Zelldepletion assoziiert. Durch die Reexpression trimolekularer HLA-B27-Moleküle wird die Interaktion zwischen immunkompetenten Zellen und HLA-B27-positiven Zellen beeinflusst, wodurch das Zellüberleben begünstigt wird. Dieser Erklärungsansatz ist vereinbar mit dem gegenwärtig favorisierten pathogenetischen Modell der fehlerhaften HLA-B27-Prozessierung und der derzeit diskutierten Beteiligung von TNF bei der Manifestation der AS.

Expression und immunmodulatorische Funktion von HLA-G und seinen verkürzten Isoformen in Tumorzellinien

Das nicht polymorphe HLA-Klasse-I-Antigen HLA-G wird hauptsächlich in der Plazenta exprimiert, wo es vermutlich den semiallogenen Fötus vor Angriff des mütterlichen Immunsystems schützt. Eine Besonderheit von HLA-G ist das Auftreten von mehreren verkürzten Isoformen, die von alternativ gespleißten Transkripten translatiert werden. Neben dem kompletten membranständigen HLA-G1 mit den extrazellulären Domänen a1, a2 und a3 existieren die verkürzten Isoformen HLA-G2 (∆a2), HLA-G3 (∆a2, ∆a3) und HLA-G4 (∆a3). Außerdem wurden die löslichen Isoformen HLA-G5 (HLA-G1s), HLA-G6 (HLA-G2s, ∆a2) und HLA-G7 (HLA-G3s, ∆a2, ∆a3) beschrieben. Um die Expression und Funktion einzelner Isoformen getrennt voneinander und ohne Beeinflussung durch andere MHC-Klasse-I-Moleküle untersuchen zu können, wurden Transfektanten für die Isoformen HLA-G1, HLA-G2, HLA-G4 und HLA-G5 in der HLA-Klasse-I-negativen humanen Zellinie K-562 generiert. HLA-G kann mit inhibitorischen und aktivierenden Rezeptoren auf NK- und T-Zellen in Wechselwirkung treten und so Effektorfunktionen beeinflussen. Die Expression von HLA-G kann außerdem indirekt über HLA-E auf die Zytotoxizität von NK-Zellen und T-Zellen einwirken. Die HLA-E-Expression ist abhängig von Peptiden aus den Signalsequenzen von HLA-Klasse-I-schweren Ketten. Zum Ausschluß der Koexpression des HLA-Klasse-I-Antigens HLA-E auf der Zelloberfläche wurden HLA-G1mut- und HLA-G4mut-cDNA-Vektoren eingesetzt, deren Exon 1 so verändert ist, daß kein Ligand für HLA-E zur Verfügung gestellt wird. Während in der Zellinie K-562 HLA-G1 und HLA-G5 auf der Zelloberfläche exprimiert bzw. sezerniert werden, waren die verkürzten Isoformen HLA-G2 und HLA-G4 mittels FACS-Analyse mit einer Reihe HLA-Klasse-I- und HLA-G-spezifischer Ak nicht auf der Zelloberfläche nachweisbar. Diese Ergebnisse korrelieren mit der Sensitivität dieser verkürzten Isoformen gegenüber Endo H. Aus der fehlenden Resistenz der HLA-G2- und HLA-G4-Polypeptide gegenüber Endo H ergibt sich kein Hinweis auf ihren Transport zur Zelloberfläche. Diese fehlende Oberflächenexpression von HLA-G2 und HLA-G4 könnte auf einer gestörten Assoziation mit b2m oder Bestandteilen der MHC-Klasse-I-Prozessierungsmaschinerie beruhen. Kopräzipitationsexperimente ergaben, daß nur die HLA-G1-schwere Kette mit b2m und TAP assoziiert ist. HLA-G2 ließ sich zwar mit TAP, jedoch nicht mit b2m kopräzipitieren und HLA-G4 ließ sich weder in Assoziation mit b2m noch mit TAP nachweisen, so daß diesen Isoformen ein wichtiger Bestandteil der vollständigen HLA-I-Komplexe fehlt und bei HLA-G4 außerdem die Beladung mit Peptiden gestört ist. Diese Daten sprechen gegen eine Zelloberflächenexpression der verkürzten HLA-G-Isoformen. Im Unterschied zu HLA-G1 war HLA-G5 nicht in Kopräzipitaten mit TAP zu finden. Daher scheint für diese Isoform eine stabile Assoziation mit TAP für die Peptidbeladung nicht essentiell zu sein. Zum funktionellen Nachweis von HLA-G wurden Zytotoxizitätstests mit der Zellinie NKL sowie mit PBL, NK-Zellen und LAK-Zellen aus dem peripheren Blut mehrerer Donoren durchgeführt. Dabei zeigte sich, daß die Expression der verkürzten Isoformen HLA-G2 und HLA-G4 die Zytotoxizität der verschiedenen Effektorzellen nicht beeinflußte. HLA-G1 inhibierte die Lyse von K-562 in Abhängigkeit von der HLA-G1-Expressionsstärke und wirkte sich weniger deutlich als eine entsprechende HLA-E-Expression auf die Zytotoxizität aus. Neben der Plazenta wird HLA-G auch in zahlreichen anderen Geweben exprimiert und kann in Tumoren induziert oder hochreguliert werden. Da bei verschiedenen Tumoren die MHC-Klasse-I-Expression aufgrund von Mutationen im b2m-Gen gestört ist, wurden HLA-G1-Transfektanten in der b2m-negativen humanen Zellinie Daudi etabliert. Daudi HLA-G1-Transfektanten weisen gegenüber K-562 HLA-G1-Transfektanten eine reduzierte HLA-G-Proteinmenge auf. In Abwesenheit von b2m ist HLA-G1 außerdem nicht resistent gegenüber Endo H und kann auch nach Inkubation der Zellen bei niedrigen Temperaturen und Zugabe von b2m oder Ligand nicht auf der Zelloberfläche nachgewiesen werden. Da von HLA-B27 bekannt war, daß b2m-freie Homodimere auf der Zelloberfläche exprimiert werden können und eine Dimerisierung von HLA-G über ungepaarte Cysteinreste möglich ist, wurden die Daudi HLA-G1-Transfektanten auf Anwesenheit von HLA-G1-Dimeren untersucht. In Abwesenheit von b2m waren jedoch keine Dimere nachweisbar. Auch in funktionellen Experimenten mit LAK oder gd T-Zellen hatte die HLA-G-Expression in Daudi HLA?G1-Transfektanten keine Auswirkung auf die Zytotoxizität oder Proliferation der Effektorzellen. Die HLA-G1-Expression in b2m-negativen Tumoren trägt daher nicht zur Tumorprogression bei. Eine Analyse der Unterschiede in der Expression und der Auswirkungen der HLA-G-Isoformen in verschiedenen Zellinien könnte Hinweise auf die Regulation und die Funktion der HLA-G-Expression liefern.

Aims: An association between inflammatory bowel disease (IBD) and spondyloarthropathies (SpA) has repeatedly been reported. The aim of the present study was to investigate whether serologic markers of IBD, e. g. antibodies against Saccharomyces cerevisiae (ASCA), antibodies against exocrine pancreas (PAB) and perinuclear antineutrophil cytoplasmic antibodies (pANCA) are present in HLA-B27-associated SpA. Methods: 87 patients with HLA-B27-positive SpA and 145 controls were tested for ASCA, PAB and pANCA employing ELISA or indirect immunofluorescence, respectively. Antibody-positive patients were interviewed regarding IBD-related symptoms using a standardized questionnaire. Results/Conclusion: When compared to the controls, ASCA IgA but not ASCA IgG levels were significantly increased in patients with SpA, in particular in ankylosing spondylitis (AS) and undifferentiated SpA (uSpA). pANCA were found in increased frequency in patients with SpA whereas PAB were not detected. The existence of autoantibodies was not associated with gastrointestinal symptoms but sustains the presence of a pathophysiological link between bowel inflammation and SpA. Copyright (C) 2004 S.

Impaired Intracellular Transport and Cell Surface Expression of Nonpolymorphic HLA-E

The assembly of the classical, polymorphic major histocompatibility complex class I molecules in the endoplasmic reticulum requires the presence of peptide ligands and ~2-microglobulin (~2m). Formation of this trimolecular complex is a prerequisite for e~cient transport to the cell surface, where presented peptides are scanned by T lymphocytes. The function of the other class I molecules is in dispute. The human, nonclassical class I gene, HLA-E, was found to be ubiquitously transcribed, whereas cell surface expression was dif~cult to detect upon transfection. Pulse chase experiments revealed that the HLA-E heavy chain in transfectants, obtained with the murine myeloma cell line P3X63-Ag8.653 (X63), displays a significant reduction in oligosaccharide maturation and intracellular transport compared with HLA-B27 in corresponding transfectants. The accordingly low HLA-E cell surface expression could be significantly enhanced by either reducing the culture temperature or by supplementing the medium with human ~2m, suggesting inefficient binding of endogenous peptides to HLA-E. To analyze whether HLA-E binds peptides and to identify the corresponding ligands, fractions of acid-extracted material from HLA-E/X63 transfectants were separated by reverse phase HPLC and were tested for their ability to enhance HLA-E cell surface expression. Two fractions specifically increased the HLA class I expression on the HLA-E transfectant clone.

Antigen HLA-B27 is a high-risk genetic factor with respect to a group of rheumatoid disorders, especially ankylosing spondylitis. A cDNA library was constructed from an autozygous B-cell line expressing HLA-B27, HLA-Cw1, and the previously cloned HLA-A2 antigen. Clones detected with an HLA probe' were isolated and sorted into homology groups by differential hybridization and restriction maps. Nucleotide sequencing allowed the unambiguous assignment of cDNAs to HL4-A, -B, and -C loci. The HLA-B27 mRNA has the structural features and the codon variability typical of an HLA class I transcript but it specifies two uncommon amino acid replacements: a cysteine in position 67 and a serine in position 131. The latter substitution may have functional consequences, because it occurs in a conserved region and at a position invariably occupied by a species-specific arginine in humans and lysine in mice. The availability of the complete sequence of HLA-B27 and of the partial sequence of HLA-Cw1 allows the recognition of locus-specific sequence markers, particularly, but not exclusively, in the transmembrane and cytoplasmic domains.
