Dysautonomia is an umbrella term used to describe disorders of the autonomic nervous system (which controls all the automatic functions of the body like blood pressure, heart rate, digestion, temperature regulation, etc.). Dr. Svetlana Blitshteyn, a board-certified neurologist and director of the Dysautonomia Clinic, joins us as we dig into these disorders and explore their defining features.
POTS (Postural Orthostatic Tachycardia Syndrome), small-fiber neuropathy, and neurocardiogenic syncope are frequent comorbidities with EDS (Ehlers-Danlos Syndromes), Marfan Syndrome, and other disorders of connective tissue. Dr. Blitshteyn discusses who is considered high-risk for POTS, explains neurocardiogenic syncope and small-fiber neuropathy, and talks about the difference between the three disorders. She explores common symptoms of POTS and outlines frequent comorbidities such as MCAS (Mast Cell Activation Syndrome), IBS (Irritable Bowel Syndrome), and EDS.
Finally, Dr. Blitshteyn answers the question - Is there a link between dysautonomia and autoimmune issues?
An in-depth exploration of dysautonomia and what that might entail for the hypermobile population, this episode is important for patients and healthcare professionals alike who are eager to learn about these complex disorders.

Jennifer Milner
Dr. Blitsheyn. Hello and welcome to Bendy Bodies. Thank you so much for having you today. So let's start with you.
00:02:20
Dr. Svetlana Blitsheyn
The basics. Dysautonomia simply means abnormal autonomic nervous system, and it's synonymous was the autonomic dysfunction of any kind. What exactly is dysautonomia simply means abnormal autonomic nervous system, and it's synonymous was the autonomic dysfunction of any kind. It's not the diagnosis. It's a descriptive term like headache, which doesn't specify what type of headache or why the headache is taking place. It's important to remind ourselves that there is sympathetic and parasympathetic nervous system and each of these systems can malfunction resulting in specific syndromes and disorders within this umbrella term of dysautonomia.
00:03:00
Dr. Svetlana Blitsheyn
Our specific diagnosis was their objective criteria that have been defined. None of these autonomic disorder diagnosis are subjective and all have objective clinical criteria. The diagnosis relies on their assessment of blood pressure and heart rate in the supply and standing position using a simple 10 minute stand test that can be performed at the doctor's office or tilt table tests.
00:03:29
Jennifer Milner
Excellent. Okay. What might make someone suspect that they have some dysautonomia?
00:03:37
Dr. Svetlana Blitsheyn
So, clinical symptoms of dysautonomia are numerous and the most common ones are orthostatic intolerance. That's the defining feature of an autonomic disorder. What that means is in difficulty standing and multiple similar symptoms arising on standing position and symptoms improving when you sit down or lie down. Of course, this is the hallmark, but there are other symptoms such as chronic dizziness, palpitations, tachycardia, lightheadedness, headaches, brain fog, sleep problems, and many others. When you sit down or lie down, of course, this is the hallmark, but there are other symptoms such as chronic dizziness, tations, tachycardia, lightheadedness, headaches, brain fog, sleep problems, and many others.
00:04:22
Jennifer Milner
Okay. Are there specific populations that might be at a higher risk for dysautonomia and as we are the bendy bodies podcasts, why should bendy people, why should hypermobile people know about it?
00:04:37
Dr. Svetlana Blitsheyn
Dysautonomia again as an umbrella term encompasses a wide variety of autonomic disorders, the most common ones being postural orthostatic tachycardia syndrome. Neurocardiogenic syncope, both of these disorders commonly occur in young women between ages 15 and 50, but of course, younger patients and older patients can also have pots or neurocardiogenic syncope. Many of these women are, of childbearing age and most of the young women are Caucasian, how it relates to Bendy Bodies. Well, we know that one of the common co morbidities of parts is Ehlers-Danlos syndrome and multiple studies showing a prevalence of about 25 to 30%, and, commonly when we have patients with pots, we must think about evaluation and, assessment for Ehlers Danlos syndrome.
00:05:48
Dr. Svetlana Blitsheyn
You often will, if you see someone who has a hypermobility in pots that will lead you to talk about looking at, an EDS.
00:05:58
Dr. Svetlana Blitsheyn
Well, so in my clinic, of course I have many patients with EDS and pots. How I figured this out is from history. When patients present to us, they're not going to volunteer the textbook information. Some will say that they have been hypermobile, but mainly will present with complaints of joint pain, a body pain, easily dislocate the joints, easy bruising and many other manifestations. It's up to us clinicians to listen to the history and figure out is this a patient that may have Ehlers Danlos syndrome, on another hand, one may say that anyone presenting with parts, should be screened for EDS. That's certainly a good practice in those of us who see a large number of patients.
00:06:56
Dr. Linda Bluestein
We know that in 2017, that criteria for hypermobile, the criteria for all the Ehlers Danlos syndromes changed with the international consortium, right? So, in particular, the criteria changed for hypermobile EDS and then they introduced the new classification, HSD or hypermobility spectrum disorders. In, in your experience, does
the overlap between dysautonomia and specifically pots? does that hold true also for the hypermobility spectrum disorders or is that more specific to EDS?
00:07:32
Dr. Svetlana Blitsheyn
Oh, that's a great question. I don't think there is answer to that. All of the studies that have been done are looking at association between pots and Ehlers-Danlos syndrome, specifically the hypermobile type A, but the scores, the hypermobility spectrum disorders are much more common and the hypermobility as a sign is very common and by no means they constitute a disorder. This is something I have to always remind my neurology colleagues who think, well, everyone, all of the young women who present with migraine or, dizziness, all of them are quite hyper mobile. They're all gymnast or dancers or swimmers. Of course we have to make a distinction that having a hypermobility as a sign absolutely does not constitute a hypermobile Ehlers-Danlos syndrome. There are criteria that needs to be met there.
00:08:34
Jennifer Milner
Yes, yes. I agree with that. So, when you're talking about, looking at pots with hypermobility, you said earlier that you do, there are a couple of really easy tests for pots, the stand test and the table tests. What, is there more of a diagnostic workup that is recommended for and how prevalent is that kind of a workup? Okay.
00:09:01
Dr. Svetlana Blitsheyn
I'll describe how I do these evaluations, because I think it's important for clinicians to hear, what the process may be. All us, all neurologic evaluations, I start to lose the physical exam after I take a thorough history and listen to the patients and all of the complaints and the physical exam includes for the study blood pressure and heart rate measurement. You lay down the patient, allowing them to rest for a few minutes, and then you measure their blood pressure and heart rate. After that you stand them up. She had their blood pressure and heart rate again increments of two to three minutes for a 10 minute stand test. This easy in-office test is very important because it can give you clues whether at disorder of the orthostatic intolerance is present. Now in the time of social distancing, I asked the patient to perform the same test in the comfort of their own home.
00:10:01
Dr. Svetlana Blitsheyn
This gives me a good approximation of what their vital signs are doing while they're supine and standing following that. It's important to do a full neurologic exam with a special attention to the sensory exam, because at least 50% of patients with pots have more bit small fiber neuropathy, regarding diagnostic tests. I usually order a lot of tests to look for possible underlying causes, to exclude pots mimics, and to look for common comorbid conditions, some specialists, however, and even some consensus statements recommend minimal workup. That usually includes EKG, basic blood work and thyroid function tests. Personally, I prefer to go beyond that in order to be thorough and not to miss any other diagnosis. Typically my patients have seen at least a dozen of other physicians and the basic workup is complete by the time they see me in terms of neurologic evaluation, if the patient has headache, which, the most common comorbidity with POTS, and also Ehlers Danlos, I obtain MRI of the brain without contrast one time to rule out structural abnormalities, like your information, and then patients with POTS, MRI of the brain is usually entirely normal, which can be very reassuring.
00:11:25
Dr. Svetlana Blitsheyn
On that note, if there is a significant sleep disturbance, which can happen in our patients with pots, and certainly in patients with Ehlers-Danlos syndrome, I refer the patient for a sleep study with obstructive sleep apnea, central sleep apnea, narcolepsy, and other sleep disorders may be present. In many cases, I refer the patient for it's still table tests for diagnostic confirmation, because in some cases where access to a tilt table test is difficult. In some cases where access to wait till table test is difficult. In some cases where access to wait till table test is difficult. I rely on the 10 minutes stand test, which we call a poor people's tilt table tests. Most of the time when there is access to tilt table tests, I certainly order that.
00:12:20
Jennifer Milner
That's great. Thank you. You mentioned a small fiber neuropathy. I know there are other issues that Chiari malformation, so I'm wondering, first of all, purely out of curiosity on my side, just from what I've seen with some of my dancers, do you see a fair amount of Chiari malformations in people with connective tissue disorders?
00:12:40
Dr. Svetlana Blitsheyn
Yes. In patients with Ehlers-Danlos I certainly see more Chiari malformation. If you ask me that question, in terms of my pots patients, I would have to say, no.
00:12:54
Dr. Linda Bluestein
Just explain for the listeners that are not familiar. Could you explain what both Chiari malformation and small fiber neuropathy what they are and why they are relevant in this conversation?
00:13:04
Dr. Svetlana Blitsheyn
Chiari malformation is usually like congenital malformation of the cerebellum, the back part of the brain, where normally it has to be above the foramen Magnum, which is an opening between the skull and the spine. And, Chiari malformation, you have cerebellum specifically the cerebellar tonsils protruding down through the foramen Magnum, and if it's, protruding more than by five millimeters down, that can be symptomatic. The symptom set may include those that are related to the obstruction of the CSF flow of this cerebral flow. Also those that can potentially, compress brainstem and cerebellum itself naturally when you have a connective tissue disorder with weakness and abnormalities in collagen, ligaments, and the even muscles may become loose and, no longer normal in structure or function. That weakness in a ligament tissue may resolve in protrusion of brainstem cerebellum. Similarly, elsewhere in the body, you may have similar situations where we refer that to hernia where organs or tissues protrude through a weak, muscular wall.
00:14:50
Dr. Svetlana Blitsheyn
Small fiber neuropathy refers to abnormal structure of small nerve fibers that are everywhere in the body and autonomic neuropathy. Isn't the same as small fiber neuropathy. There needs to be a distinction made, a thin unmyelinated, alpha and Delta fibers that, underlies small fibers, may be damaged and they may be damaged by toxins, medications, antibodies, or alcohol, diabetes, and many other conditions, which results in, neuropathic pain and objective findings that we see on neurologic exam, which traditionally includes a loss of, temperature, sensation and pain sensation. This distinction made, a thin unmyelinated, alpha and Delta fibers that, underlies small fibers, may be damaged and they may be damaged by toxins, medications, antibodies, or alcohol, diabetes, and many other conditions, which results in, neuropathic pain and objective findings that we see on neurologic exam, which traditionally includes a loss of, temperature, sensation and pain sensation. That's a very important part of neurologic exam.
00:15:51
Dr. Svetlana Blitsheyn
That's how we can identify our patients with pots and Ehlers Danlos who may have small fiber neuropathy. At least 50% of patients with spots have small fiber myopathy objectively confirmed, and at least 70% of patients was hypermobile Ehlers-Danlos syndrome. Also have small fiber neuropathy is very important for clinicians to
identify that and the way to diagnose it is of course, we ask questions on history on the questions will be surrounding neuropathic pain. Not always the patients will have burning pain or numbness tingling. Sometimes they will have itching. Sometimes they will describe a full body paint, a bone kind of pain. Sometimes they'll describe this as having rubber bands on their feet. Sometimes they will describe the pain as, a sensation of heat or having heavy legs. When we have this history and we have findings on our exam of sensory dysfunction, we must obtain very important.
00:17:02
Dr. Svetlana Blitsheyn
Two tests. One is a test of EMG, which is a test of muscles and nerves that will identify whether the patient has large fiber neuropathy. The second test is a skin biopsy to investigate whether the patient has small fiber neuropathy. Very important point is that when we in medical world suspect that our patient has neuropathy, we must order two tests. One is EMG test of large fibers, and another test is a skin biopsy or test the small Hybris. There is also, a full autonomic function test that is only in certain areas of the country. That's, unfortunately isn't available to all of us everywhere, but there is an important test there called acute quantitative. The motor X and reflux tests that can measure sweat output and determine whether a patient has a small fiber neuropathy, with that method.
00:18:14
Dr. Linda Bluestein
Very good. And, and we wanted to have more of an explanation in terms of, syncope. You had mentioned earlier, like neurocardiogenic syncope, and again, some of our listeners, they heard the word syncope they'll know what that means, others won't. Could you just explain more about that?
00:18:32
Dr. Svetlana Blitsheyn
Sure. Neurocardiogenic syncope is a condition that usually is viewed as an episodic autonomic disorder, meaning that in between the episodes of syncope, the patient remains asymptomatic. Now we've got to make this distinction. Syncope is very common in everyone. In the lifetime, at least 25% of all patients may have a syncopal event, especially when they're younger and that the cons for a great majority of ER presentations. This is what we call a simple syncope, single, simple, faint, single, simple syncope, or simple vasovagal syncope as it is commonly called in the medical world. These are events that are common and not necessarily representative of a disorder. This becomes only a disorder when syncope is repetitive. Of course, to a significant frequency, it obviously becomes disabling when that the car's very frequently and then pairs your functional status. And clearly it becomes extremely disabling. When you have syncope, every time you stand up, it does come, we affect young people.
00:19:52
Dr. Svetlana Blitsheyn
It was the onset of puberty, which is the most common age of onset, not only for new or cause of genic syncope, also commonly it's a common age of onset for postural orthostatic tachycardia syndrome during a period of growth spurt or, during, the onset of menstruation. One can have these, dysregulation of the autonomic nervous system, again, in and of itself. It may not represent a disorder, but when it's repetitive and affects your function and when it's repetitive and affect your functional status, then it becomes a medical condition that needs medical attention, briefly put syncope just means an abrupt loss of a suitable blood flow. When that happens, obviously you fall down and that's a body's natural way in restoring cerebral perfusion and blood flow back to your brain.
00:21:04
Dr. Linda Bluestein
Syncope is basically when you get a syncope or presyncope also, right, so people can have syncope or complete loss of consciousness, or they can feel like they're going to pass out. Both of those would happen in like, for example, pots, is that true?
00:21:19
Dr. Svetlana Blitsheyn
Okay. So let's make some distinctions here. Apart is defined. Pots as a disorder has three clinical criteria. One is you need to meet a criteria of an increase in heart rate by at least 30 beats per minute, within 10 minutes, then tests or a tilt table test, and at least 40 beats per minute in teenagers, or those who are under the age of 19 that's number one criteria. Number one criteria. Number two is blood pressure remained stable during that time. Number three is the chronicity of symptoms where symptoms must be present. Symptoms of orthostatic intolerance must be present for at least six months. That's the definition of parts of the definition of neurocardiogenic syncope is an abrupt drop in both heart rate and blood pressure within 10 minutes of standing associated with loss of consciousness. And that's the criteria for neurocardiogenic syncope. We also have a criteria for orthostatic hypotension, which is another common disorder that involves a drop in blood pressure by more than 20 over 10 millimeters of mercury, within three minutes of a tilt table test.
00:22:51
Dr. Svetlana Blitsheyn
If the heart rate does not rise in compensation to a decreasing blood pressure, we call that neurogenic orthostatic hypotension. Now that we know these three distinct patterns, now you asked a very important question in parts, do these patients pass out? Do they come close? What's going on there? So of course, if we go by defined clinical criteria, once you meet criteria for parts by exclusion, you can not meet criteria for new Yorkers, genic, syncope. However, if you go to the clinical world of reality, that some patients will faint as well. In addition to having pots, some patients will faint at least 25 to 30% of patients with pots can faint. Most patients do not. Most patients come close, they feel like they're going to faint, but they never do what we call presyncope. We think it's because the physiology still compensating. When you have a kind of a slower to decrease in cerebral perfusion, perhaps you have activation of autonomic reflexes that they're still preserving, based on this increase in heart rate that are still preserving some perfusion to the brain and therefore you do not pass out.
00:24:20
Dr. Svetlana Blitsheyn
It's a very important distinction to make. Now, some people will have abnormal tilt table test showing your polygenic syncope. As I mentioned before, transition, traditionally your current agentic syncope is viewed as an episodic disorder, meaning that in between the episodes of syncope, the patients should be asymptomatic again, when you, practice in reality, there are also patients who have neurocardiogenic syncope confirmed, they pass out, and then between the episodes of syncope, they will have disabling symptoms such as fatigue, lightheadedness, dizziness, headaches, and all the rest of the symptoms of dysautonomia.
00:25:06
Jennifer Milner
Yes. I wanted to follow up with you on some of the things that you mentioned with the fatigue and the headaches. Can you go more into what are some of the common symptoms, and co-morbidities, that might go along with people who have been diagnosed with pots.
00:25:22
Dr. Svetlana Blitsheyn
We divide symptoms of packs into two categories. One is orthostatic. The orthostatic symptoms such as dizziness, palpitations, lightheadedness weakness, and overall feeling faint. The second category is non orthostatic symptoms. These includes general symptoms such as fatigue, chronic dizziness, headaches, brain fog, which is difficulty concentrating and other symptoms of cognitive dysfunction, sleep disturbance, and the, sometimes the alterations in mood. These are the non orthostatic symptoms of the set. Dysautonomia comorbidities is a very common, as they always say, paths, rarely exists alone. The Nomia comorbidities is a very common, as they always say, paths, rarely exists alone. At least 80% of patients with pots have significant co-morbidity at least one the most common comorbidity. As I mentioned before, it's small fiber neuropathy occurring in at least 50% of patients with pots. Another very common comorbidity is headache, across, in at least 40% of patients with a third common comorbidity is Ehlers-Danlos occurring in at least 25% of patients with pots.
00:26:51
Dr. Svetlana Blitsheyn
And then we have other comorbidities. One of them is a mast cell activation syndrome, and now there is irritable bowel syndrome. There are Comorbid or immune conditions affecting at least 25% of all patients with spots with the most common, what immune condition being Hashimoto's thyroiditis.
00:27:15
Jennifer Milner
Excellent. Thank you.
00:27:17
Dr. Linda Bluestein
You wrote a paper on, B-1 deficiency in pots. Would you be able to elaborate on that?
00:27:25
Dr. Svetlana Blitsheyn
Okay. Vitamins deficiency is quite common in our patients was the most common being iron deficiency without anemia. Levels of vitamin B12 also appear to be lower in our patients compared to the age matched controls in terms of vitamin D one deficiency. I am aware only of my study and in my cohort of 65 patients, the prevalence of vitamin B1 deficiency was 4%, unfortunately only one patient out of that. KC serious, recovered with vitamin B one supplementation. Regardless of that fact, I personally always check all of my patients with spots for common vitamin deficiencies, including B12 B-1, D Iron, B-6 and others.
00:28:32
Jennifer Milner
Excellent. Thank you. Looking at these disorders at pots specifically, but also some of the others that you've talked about, just so people know how disabling can these disorders be and especially if not diagnosed and treated and how could someone avoid getting to that point?
00:28:55
Dr. Svetlana Blitsheyn
It's a very good question from multiple studies. We know that pots can be quite disabling as congestive heart failure and at least 25% of our patients are unable to work or attend school. And, prognosis, has been a little tricky. A question, about the decade ago, there was a notion among our colleagues that you can outgrow pots. The statement came from one earlier study that suggested that 80% of patients no longer experienced past five years after they were diagnosed; many of us who specialists in pots simply were not seeing these high numbers in real life. More recently, there was a study out of Mayo clinic that painted a more realistic picture by demonstrating that only about 50% of teens with pots improve, but only 19% fully recover. That was a mean followup of five years. So, why, while we would love to tell patients that pots has a good chance of recovery.
00:30:13
Dr. Svetlana Blitsheyn
I think reality is that parts is going to be a chronic disorder that can fluctuate in severity for a majority of patients. The range of severity varies greatly with some patients being able to work, travel, and participate in sports while others will have significant difficulty doing all of those things. I think a realistic approach to long term prognosis is a lot better than painting a rosy picture and telling young patients that may outgrow pots in their twenties only to get their hopes that they're at one that doesn't happen. Now, having said that seams appear to have a better prognosis than adults with pots. They certainly have patients who were very sick during their teen years and unable to attend school, but then improve enough to be able to attend college and do all their age appropriate things. So, in summary, I tell my patients that prognosis is hopeful, but expectations for a full recovery need to be tapered and lifestyle adjustments, as well as some form of medical management should be expected.
00:31:26
Dr. Linda Bluestein
And, and I wanted to follow up with actually this what you were just saying in terms of expectations and this age group. I'm thinking that this ties in with the B-1 question that, this is a group of kids that would be doing, like I said, age appropriate things, which of course also includes, drinking alcohol and many instances as they
turn 21. And, but with the potential for vitamin B deficiencies, and of course the potential effects of alcohol on other, hemodynamic variables, I guess, do you have any advice for, listeners about that?
00:32:02
Dr. Svetlana Blitsheyn
Interestingly, a lot of our patients have alcohol intolerance. They're not drinkers. They figure out early on that, alcohol makes them feel worse. Alcohol may result in a drop in blood pressure, alcohol causes flushing and make call lead to mass cell activation. Alcohol causes sleep disturbance, alcohol can cause balance difficulties. Many of our patients, do not drink. Sometimes adults would be able tolerate a glass of wine and there, but a majority of our patients do not consume alcohol. Now it seems we'll be teens and college students will be college students. They do advise to stay away from alcohol. If you have to socialize, and if you have to go to a party, limit your alcohol intake to no more than one drink per night, and that's very little and the grand scheme of things about, it's not worth causing an exacerbation of your pots and other comorbid conditions.
00:33:12
Dr. Svetlana Blitsheyn
It's not worth ending up missing the next day of school because the day before the night before you were drinking alcohol. Being very cognizant of negative impact of alcohol on our patients, yet understanding that saying don't ever drink alcohol, or you shouldn't drink alcohol at all isn't also realistic. Isn't also realistic. Limit your alcohol intake, if you must no more than one drink. Of course, if you have to drink, don't drive, ask for a ride.
00:33:47
Jennifer Milner
Excellent. Thank you. I'm wondering in this whole big picture, how does auto-immunity fit into all of this?
00:33:56
Dr. Svetlana Blitsheyn
There has been significant research interests in the past few years to determine whether pots is an auto-immune disorder. While we haven't conclusively answered this question thoroughly, yet it does appear that pots may have a strong autoimmune basis. Years ago, I received a grant to study auto-immune markers in all things in disorders. In patients with pots, I noticed that a significant number of my pots patients had positive markers of autoimmunity and comorbid autoimmune disorders. We, when we applied statistical analysis, we did find that past patients had a higher prevalence of nuclear antibodies, antiphospholipid antibodies and other markers than the general population. The prevalence of most defined autoimmune conditions was higher in my cohort of a hundred patients with pots then in general population, with any type of autoimmune disorders affecting one in five patients with spots and Hashimoto's thyroiditis being the most prevalent condition affecting about 11% of our patients.
00:35:13
Dr. Svetlana Blitsheyn
Over the past few years, various antibodies have been identified in patients with pots. These antibodies are critical to the structure and function of the sympathetic and parasympathetic nervous system. It makes sense that these antibodies would be potential biomarkers in this disorder. Now, last year we have made significant the one by Dr. David Kim from the university of Oklahoma, who immunized rabbits with adrenergic receptor peptide and simulate the pots in rabbits. All of these findings undoubtedly have therapeutic implications was immunotherapy, which is already being used in certain selected patients with spots quite effectively.
00:36:03
Dr. Linda Bluestein
Are you referring to subcutaneous, gamma globulins and also IVIG. Are you referring to subcutaneous, gamma globulins and also IVIG. Can you elaborate on that?

Transcript for Bendy Bodies Podcast, Episode 21: Demystifying Dysautonomia with Dr. Svetlana Blitsheyn
00:36:25
Dr. Svetlana Blitsheyn
Yes. The, topic of immunotherapy in patients with spots is growing, there is a, there is emerging evidence through large case small case studies that immunotherapy in the form of IVIG and sometimes plasma have been very effective in our most disabled patients with pots refractory to standard medications. Interestingly, you mentioned subcutaneous immunoglobulin, on presenting a case series of patients with spots who improve significantly with subcutaneous immunoglobulin. I am presenting this research at the upcoming American Autonomic Society meeting in November. What we know is that many of these patients have positive antibodies, whether it's going to be adrenergic antibodies that as unfortunately are not available on clinical basis to obtain in the United States, whether it's going to be into nuclear antibodies, but the antibodies there is always some kind of abnormal immune marker. That's very important because this further suggests that in these patients refractory to standard therapy and by standard therapy, I don't mean, fluids and salt intake.
00:38:04
Dr. Svetlana Blitsheyn
I mean, all of the available medications that we have for pots, these patients have failed, have not been proved. They're essentially bed bound, that we should consider immunotherapy in these patients. Now, large studies, clinical trials, placebo controlled studies are underway to determine whether IVIG is effective in patients with pots, but then see those studies become available. As we know, these studies take a long time and a lot of resources to complete. We already have preliminary evidence from real life cases and case serious that outlines significant improvement in these patients. For example, in my case, two patients have gone from bed bound to working full-time, when they were given subcutaneous immunoglobulin in the span of six to nine months. You need to be very cognizant and we need to push the insurance companies to cover these, effective therapies, because the cost of coverage of immunoglobulin, whether in the IVA in the intravenous or subcutaneous cost is going to be a lot less than the cost of covering a medical care for a very disabled individual who is 20, 30 years old, and have many years ahead of them.
00:39:41

That's a very important point that we need to emphasize. Similarly, a lot of my patients ask me, well, can I get IVG because they have heard that IVIG can be very effective. We need to understand that IVIG is a blood product. That IVIG is very expensive, that insurance needs to cover it. Not everyone who walks through your door as a pots patient will need to have IVIG. You need to go through the standard therapy first. We have to emphasize to the patients, clinicians, and insurance companies, that it's only those who are refractory, who failed to improve with standard medications, who are very disabled, young people who are unable to participate in school or work. Those are the patients that need to be tried on the immunotherapy.
