- 0:03Caitlin Whyte (Host): This is Flourish.
- 0:04I'm Caitlin White, And with us today is Dr.
- 0:07Ana ANI.
- 0:08a rheumatologist from Prisma Health.
- 0:10We're diving into the complexities of living with an autoimmune disease.
- 0:15Well, doctor, my first question for you today is how do autoimmune diseases
- 0:19develop and why does the immune system start attacking the body in this way?
- 0:24Dr. Ana Gowani:
- 0:24so This is a huge question and one that doesn't, have a simple answer.
- 0:28but what we do know is that there are.
- 0:30Three known factors that influence the development or pathogenesis
- 0:34of an autoimmune disease.
- 0:36So, that's genetics.
- 0:38the immune system And then the environment.
- 0:41a patient's genes can increase the risk, or genetic susceptibility
- 0:45for an autoimmune disease.
- 0:47Numerous genes have been shown to increase the risk for
- 0:49developing autoimmune diseases.
- 0:51we know about 80 genes in lupus thus far.
- 0:54however, the individual impact is small.
- 0:57And so apart from a few very rare autoinflammatory disorders that occur due
- 1:02to defects in one single gene, there's typically not one genetic abnormality
- 1:07at the root of an autoimmune disorder.
- 1:10And so, the immune system has multiple regulatory mechanisms that help, prevent
- 1:16sort of autoreactive lymphocytes from developing And in autoimmune disease.
- 1:20these regulatory mechanisms break down.
- 1:23so there's various ways that this can happen.
- 1:26This can be due, to defective functioning of.
- 1:29Antigen presenting cells like dendritic cells or macrophages or
- 1:32due to a decline in the function or number of regulatory T cells.
- 1:36but again, there are sort of multiple areas, in the immune
- 1:40system where these, again, regulatory mechanisms can, Not work correctly.
- 1:44so finally, environmental factors are felt to contribute to autoimmune disease.
- 1:49So tobacco use or, cigarette smoking has been linked to an increased risk,
- 1:53to rheumatoid arthritis development.
- 1:56And then other factors like pollutants or exposure to certain viral infections
- 2:00are felt to play a role as well.
- 2:03Caitlin Whyte (Host): So just why are autoimmune disorders often
- 2:06difficult to diagnose, And what are the most common early warning signs?
- 2:11Dr. Ana Gowani:
- 2:11so the challenge is that typically there isn't one laboratory test that.
- 2:15Definitively diagnose a patient with a specific autoimmune disorder.
- 2:19So a test that's commonly ordered by, various providers is an a NA or
- 2:24anti-nuclear antibody test, which has a range of patterns and titers or degrees
- 2:29of positivity, and is a non-specific test.
- 2:32And I've had multiple patient's come to me saying that they were told that they had
- 2:35lupus because they had a positive a NA.
- 2:38When an a NA actually occurs in about 16% of the general population are almost one
- 2:43in five people, And that number rises to about 30% or almost one in three people
- 2:48when patient's are 60 years and older.
- 2:51And so just having a positive a NA isn't diagnostic of
- 2:54having, an autoimmune disorder.
- 2:56Most autoimmune diseases are diagnosed based on clinical history with
- 3:00presentation of certain clinical features, partnered with specific laboratory
- 3:04studies, including autoantibodies.
- 3:06but it's important to see a rheumatologist for evaluation and diagnosis.
- 3:10and there are, many presentations of autoimmune disease.
- 3:14so the early warning signs can vary, but one warning sign that can be seen is the
- 3:18development of new onset Reno phenomenon.
- 3:21And an older individual.
- 3:22So OID phenomenon is vasospasm of the digits during which it can look
- 3:27like someone's tied a tourniquet around the middle of your fingers,
- 3:30resulting in severe blanching or pale skin that has a clear demarcation.
- 3:35Then as if the tourniquet was released, the fingers can become red due to
- 3:39increased blood flow back to the fingers.
- 3:41And so This is very common in young women.
- 3:44But features of Reno phenomenon that would be concerning for a possible
- 3:48underlying autoimmune disease would be older onset, typically after the age of
- 3:5230, intense or painful episodes that can even result in ischemic digits or
- 3:57digital ulcers or asymmetric attacks.
- 4:01Caitlin Whyte (Host): Well, you mentioned before that environment and lifestyle
- 4:04come into play a bit when it comes to developing these diseases, but I'd
- 4:08love to also talk about the genetics.
- 4:10What role do genetics have in autoimmune diseases and why do
- 4:14they affect women more than men?
- 4:17Dr. Ana Gowani:
- 4:17so one study recently, evaluated electronic health record data from six
- 4:22large medical systems using a software program that generated an estimated
- 4:27prevalence of autoimmune disease.
- 4:29And so in that particular study, about 4.6%
- 4:32of the US population had an autoimmune disease.
- 4:35Of those patient's, 63% of them were female.
- 4:39in this study, women were twice as likely as men to be diagnosed
- 4:42with an autoimmune disease.
- 4:44And for some diseases such as lupus or Sjogren's disease, the ratio
- 4:48of women to men being diagnosed.
- 4:50Has been, reported as high as about nine to one.
- 4:53So there are many proposed explanations for the difference in prevalence,
- 4:57including hormonal differences, environmental factors, or even the
- 5:01expression of the X chromosome.
- 5:03So it's known that men carry one X chromosome while women
- 5:07carry two x chromosomes.
- 5:10And so normally in nature, one chromosome in women is inactivated
- 5:14to avoid gene overexpression.
- 5:17And overproduction of certain proteins.
- 5:20So one, recent study published in nature was looking at whether these,
- 5:25RNA protein, DNA complexes that are generated to help inactivate that X
- 5:30chromosome, whether or not they play a role in triggering autoimmunity.
- 5:34But at this time, there's still a lot of research being done to help
- 5:37investigate these questions further.
- 5:40Caitlin Whyte (Host): Well, what are some of the biggest misconceptions that
- 5:42patient's have about autoimmune disorders?
- 5:45Dr. Ana Gowani:
- 5:45I think that the term inflammation is used in very generalized terms
- 5:51and can, sometimes be misinterpreted.
- 5:54So people will often come in using the phrase, I feel
- 5:56inflamed, or I have inflammation.
- 5:59but a lot of the time that actually translates into, pain or discomfort.
- 6:04And so.
- 6:05there is both inflammatory pain and non-inflammatory pain, and both types of
- 6:11pain can be severe, but it's important to differentiate between the two
- 6:15because the treatment is very different.
- 6:17Caitlin Whyte (Host): Well, that brings us to our next question.
- 6:19How have treatment options such as biologics and personalized
- 6:24medicine changed patient outcomes?
- 6:26Dr. Ana Gowani:
- 6:26the treatment landscape and rheumatology has changed dramatically
- 6:30over the past few decades.
- 6:32As an analogy, the difference in treatment previously versus now is as
- 6:37if you were using towels to dry up water from a running faucet versus now having
- 6:41the ability to turn the faucet off.
- 6:44And so there are many cells that are important in the immune system.
- 6:47but two important players are your B cells and T cells.
- 6:50And so B cells move through the body to help differentiate between ourselves
- 6:55and proteins that shouldn't be there.
- 6:57They can help detect viruses such as influenza and help produce antibodies
- 7:02to coat the foreign protein.
- 7:04T cells then recognize these antibodies and help eliminate.
- 7:08the foreign protein T cells also can help generate a response to
- 7:12upregulate and produce cytokines, which help produce inflammation to
- 7:17help fight this, foreign protein.
- 7:19And so in autoimmune disease, the immune system starts to
- 7:23malfunction and instead starts to misidentify your cells as foreign.
- 7:27biologic therapies have different targets, including cytokines or these.
- 7:31Small proteins that act as messengers for the immune system that are
- 7:35important for cell signaling and can upregulate inflammatory responses.
- 7:40And so an example of this would be Tocilizumab, which is a biologic
- 7:44medication that specifically targets the cytokine interleukin six.
- 7:48In addition, some biologic agents target specific markers on a cell
- 7:52surface such as CD 20, so that they can impact a specific cell population.
- 7:57So an example of This is rituximab, which targets CD 20 express on B
- 8:02cells and can help deplete B cells.
- 8:04And so the benefit of biologics is that they're much more precise
- 8:08at targeting the underlying proteins that are causing a ruckus.
- 8:12Caitlin Whyte (Host): And then beyond medication, I'd love to go back and
- 8:14touch on lifestyle factors again, like diet, sleep, and stress management.
- 8:19Can those influence disease progression at all?
- 8:22Dr. Ana Gowani:
- 8:22So one great dietary approach is practicing the Mediterranean diet and
- 8:26avoiding a lot of processed foods.
- 8:28The Mediterranean diet includes a high intake of plant-based foods
- 8:32such as whole grains, fruits and vegetables, nuts, fish, seafood.
- 8:36one study looking at rheumatoid arthritis, patient's who are
- 8:39following a Mediterranean diet.
- 8:41In conjunction with physical activity over three months showed a significant
- 8:45reduction in the disease activity score on 28 joints, or the DAS 28,
- 8:50which is a clinical disease activity tool compared to the control group.
- 8:55And those patient's also had an improvement in metabolic
- 8:58outcomes such as body weight, body composition, and blood sugar.
- 9:02With regards to stress, there have been studies looking at rat models
- 9:05with psoriasis where rats that were exposed to unpredictable stressors
- 9:10for eight weeks had increased, in their epidermal thickness and worsened
- 9:15psoriasis compared to controls.
- 9:18Sleep disruptions are associated with poor cognitive function,
- 9:21increased pain sensitivity, and a higher risk for depression.
- 9:25So it's important to try and optimize as many lifestyle factors as possible,
- 9:30to improve health and overall function.
- 9:33Caitlin Whyte (Host): Well, how does living with an autoimmune disease
- 9:35affect your mental health fatigue and just your overall quality of life?
- 9:40Dr. Ana Gowani:
- 9:40of patient's with autoimmune disease, one study found that more than half
- 9:44can suffer from anxiety and depression.
- 9:47and while the link between autoimmune disease and mental health has
- 9:49not fully understood, you can imagine that some contributors to
- 9:53worsening, depression could be a new diagnosis of autoimmune disease.
- 9:57And the implications that may have for a patient's life.
- 10:00some medications can contribute to fatigue, And then there are other
- 10:04factors such as pain from a condition that may impact or disrupt sleep,
- 10:08which is also known to contribute to an increased risk for depression.
- 10:12Caitlin Whyte (Host): Also, how can autoimmune patient's best advocate for
- 10:15themselves when navigating medical care?
- 10:17Dr. Ana Gowani:
- 10:17So one example.
- 10:19advice is that sometimes, so using a disease, process example, so,
- 10:23patient's with diffuse scleroderma are at higher risk for a complication
- 10:27known as scleroderma renal crisis, which can be life-threatening.
- 10:31This can present with severe hypertension, rapid progressive renal failure,
- 10:37congestive heart failure, or severe.
- 10:39anemia And so since scleroderma is rare, not all medical providers are
- 10:44familiar with how to treat what is considered a scleroderma emergency.
- 10:48So, for these patient's, scleroderma renal crisis prevention card can
- 10:53actually be given to patient's with, diffuse scleroderma to
- 10:56carry with them in their wallet.
- 10:58This can describe, you know, the warning signs of new onset scleroderma renal
- 11:02crisis, such as new headaches, blurred vision, abrupt elevations in blood
- 11:06pressure, shortness of breath, et cetera.
- 11:09And it's a card that the patient can give to emergency room physicians to
- 11:13explain what may be happening to them.
- 11:15And describes the best treatment course, which is an ACE inhibitor, And so This
- 11:19is just one strategy for a particular group of patient's with a rare autoimmune
- 11:24disease designed to help improve health outcomes and help patient's advocate
- 11:28for appropriate treatment early.
- 11:31Caitlin Whyte (Host): And to close it out for us today.
- 11:32Doctor, what advice?
- 11:33Would you give patient's on improving quality of life while
- 11:37living with an autoimmune disorder?
- 11:39Dr. Ana Gowani:
- 11:39for a lot of my patient's will say to just take it one day at a time.
- 11:43a lot of times at the beginning of treatment of an autoimmune disease
- 11:46such as rheumatoid arthritis, there are a lot of moving parts in terms of
- 11:50starting new medications, obtaining screening labs or other tests.
- 11:54I think it's important to try and take it one day at a time.
- 11:56Otherwise it can become very overwhelming.
- 11:59there is a lot in autoimmune disease as well That is out of the patient's control.
- 12:04However, it is also important to try and take control of the
- 12:07factors you can control to help improve your autoimmune disease.
- 12:11For example, working on quitting smoking, trying to follow a healthy Mediterranean
- 12:16based sort of low processed food diet.
- 12:18Taking medications as prescribed, trying to practice good sleep habits
- 12:23at night, promote, good sleep, such as reducing screen time and trying to
- 12:27participate in exercise for at least 30 minutes a day, five times a week.
