- 0:03Melanie Cole, MS (Host): Welcome to Flourish: a Prisma Health podcast.
- 0:07I'm Melanie Cole.
- 0:08And today, we're talking about managing sickle cell disease.
- 0:11We have a panel for you today, and joining me is Dr.
- 0:14Gary Bell, he's a board-certified internal medicine physician at Prisma Health.
- 0:18And LaChina Moore-Hollis, she's a board-certified family nurse practitioner
- 0:22specializing in Internal Medicine and the care of adults at Prisma Health.
- 0:27Thank you both so much for joining us today.
- 0:30And Dr.
- 0:30Bell, I'd like to start with you.
- 0:32Can you please let the listeners know what is sickle cell disease, and how
- 0:36is it different when we've heard the term sickle cell anemia so many times?
- 0:41How do they differ, and who is most at risk?
- 0:44Dr. Gary Bell:
- 0:44Okay.
- 0:45Just as some background, sickle cell disease is the most common inherited
- 0:51red blood cell disorder in the United States, and upwards or over 100,000
- 0:57people are affected in the United States with sickle cell disease, and
- 1:02South Carolina has the highest rate of sickle cell disease in the US.
- 1:08And actually, about one in 350 births are affected by sickle cell
- 1:15disease, and one in nine births carry the sickle cell trait.
- 1:21And sickle cell disease itself is somewhat of an umbrella term
- 1:28for a family of blood disorders.
- 1:31And in the US and here in the clinic, we deal mainly with four types.
- 1:38The most common and perhaps the most severe form of sickle cell
- 1:43disease is the SS disease, where the child or the patient has inherited
- 1:50one sickle gene from each parent.
- 1:54That's the SS disease.
- 1:56The SC, the child inherits one sickle gene from one parent and the C
- 2:03hemoglobin gene from another parent, and they have SC disease, which if
- 2:08you want to say it's a milder form of sickle cell disease, you can.
- 2:13The other two are sickle beta thal plus, where the child inherits a single S gene,
- 2:21sickle gene from one parent and the beta thalassemia gene from the other parent.
- 2:28And the beta thalassemia sickle cell patient, they're able to
- 2:33make some normal hemoglobin.
- 2:35So, it manifests itself as clinically a milder form of sickle cell disease.
- 2:41Whereas the fourth type of sickle cell disease is the sickle beta-zero
- 2:49thalassemia, where they don't make any normal hemoglobin, and they have
- 2:53a similar clinical picture as the SS disease, and it's more severe.
- 2:59Thus, with sickle cell anemia, we usually refer to the most severe types, the SS
- 3:05and the sickle beta-zero thalassemia.
- 3:10And you ask yourself, "Well, why is that important?"
- 3:13It's important because we can anticipate how the disease can progress over time,
- 3:20and we can look for the complications that form of sickle cell disease might have.
- 3:27And if you look at, well, what population of patients are at risk for developing
- 3:36sickle cell disease, you know, as background, we do know that the genetic
- 3:42change that occurred with sickle cell disease occur in the areas of Western,
- 3:49Central, and Sub-Saharan Africa, as well as those countries that border the
- 3:56Mediterranean Sea, as well as parts of Central and South America, as well as the
- 4:01subcontinent in Asia, particularly India.
- 4:06And anyone coming from those areas are at increased risk for
- 4:12developing sickle cell disease.
- 4:14But here in the US, we know that African Americans are particularly
- 4:20disproportionately affected.
- 4:22And we see it more in the African American community, but we are seeing more of a
- 4:30Hispanic population, particularly here in the Southeast, and one in 16,000
- 4:36births in the Hispanic community can be affected by sickle cell disease.
- 4:42That's why it's important that everyone is screened at birth regardless of their
- 4:47background, their ethnicity or race.
- 4:51Because early diagnosis means early treatment.
- 4:53And that's just some background in terms of sickle cell disease itself.
- 5:00Melanie Cole, MS: Thank you so much, Dr.
- 5:01Bell, for giving us that background and really who is most at risk.
- 5:05So China, tell us a little bit about the disease course itself.
- 5:10What symptoms, complications can sickle cell disease cause?
- 5:14LaChina Hollis: So, sickle cell disease, it can really vary
- 5:17from individual to individual.
- 5:20So, everyone's so different.
- 5:22But it can cause a number of symptoms, and it's really based on the
- 5:26abnormal red blood cells breakdown.
- 5:29So, they break down early and they tend to be sticky, and they stick
- 5:33together and block blood flow, and they cause pain episodes.
- 5:38And pain is really the hallmark of sickle cell disease.
- 5:43That's the most common symptom that occurs, and that's the symptom that really
- 5:48leads patients to emergency departments.
- 5:51So, pain, really, it's sudden and it can be severe, often in the
- 5:55bones, the back, the chest, abdomen.
- 5:58It can really occur wherever sickle cells clump together and impede blood flow.
- 6:04Another symptom can be anemia, which can cause fatigue and weakness,
- 6:10dizziness, pale skin, a fast heartbeat.
- 6:14Jaundice is another symptom which can be yellowing of the eyes or skin, and it's
- 6:19a result of the breakdown of red blood cells as well; swelling of the hands
- 6:24and feet, this is particularly common in young children when it occurs; frequent
- 6:30infections particularly in children because the spleen may not be functional.
- 6:35And another symptom is delayed growth or puberty.
- 6:40So, those are just some general symptoms.
- 6:43Melanie Cole, MS: Well, so China, I'd like you to speak about how some of
- 6:47these challenges change as someone moves from childhood to adulthood.
- 6:52But what I'd also like you to mention, because you mentioned pain as being a
- 6:56hallmark, and if somebody does end up in the ER, what would you like them to know
- 7:03as they become an adult and can advocate for themselves about how to describe what
- 7:10they're going through, how to let the staff know what they're going through so
- 7:14that this can be diagnosed quickly as an episode and be treated for their pain?
- 7:21LaChina Hollis: Childhood with sickle cell disease is typically marked by
- 7:25infections and that particularly occurs with the loss of spleen function.
- 7:30So, that changes as we go into adulthood or adolescence.
- 7:35And of course, in childhood, the acute pain episodes can occur and in
- 7:40childhood, there's a stroke risk as well.
- 7:42So, adolescence, it's marked by an increase in the frequency of pain episodes
- 7:49and school disruption can occur, and the patients are transitioning from
- 7:56parent-managed care to self-managed care.
- 7:59So usually, there can be some delay in that area.
- 8:02Also, from a pediatric standpoint, there's more of a combined care or more
- 8:08multiple specialties are often involved in the patient's care with pediatrics.
- 8:13So, it's usually a little bit more involved.
- 8:16But as they transition to adulthood, the pain can be more chronic
- 8:22and it can be more cumulative organ damage as patients age.
- 8:26And it typically affects the kidneys, lungs, eyes, and bones as
- 8:32we age with sickle cell disease and often frequent hospitalizations.
- 8:37So, you asked the question since pain is the hallmark of sickle cell
- 8:42disease, what should patients tell providers when they present to the ER?
- 8:48So, the main thing is if a patient has a pain plan in place, usually,
- 8:54they know what treats their pain, what works best for their pain.
- 8:58So, a pain plan at hand is often the best course when you go
- 9:03into the emergency department.
- 9:05Melanie Cole, MS: That is great advice.
- 9:07Something really important to note.
- 9:08Now, Dr.
- 9:09Bell, speak a little bit about treatment.
- 9:11What role does lifelong treatment plan play in preventing
- 9:16some of these complications?
- 9:18Dr. Gary Bell:
- 9:18Well, as China said, the management of the acute pain is separate from
- 9:24the medications that we use to sort of modify the disease process itself.
- 9:32And right now, in the United States, there are three FDA-approved medications
- 9:38for the treatment of sickle cell disease.
- 9:41And the first one that came out was hydroxyurea back in—I think,
- 9:47it was FDA approved in 1998.
- 9:51And hydroxyurea is considered the gold standard in terms of treatment, because it
- 9:58has shown its usefulness over the years.
- 10:01And it's an oral medication, you take it by mouth.
- 10:04And it's usually started at a very young age, and the goal is to address
- 10:11the underlying issues in sickle cell disease that can cause chronic
- 10:16problems if the disease itself is not addressed at an early age.
- 10:22And hydroxyurea actually helps the body make more of the fetal hemoglobin.
- 10:29That is the hemoglobin that may be present when a child is born.
- 10:35And it keeps the red blood cells that are circulating healthier, and
- 10:39it helps prevent them from sticking to the walls of the blood vessels.
- 10:44And thus, as China said, causing clogging of the blood vessels, which
- 10:51delays the delivery of oxygen to the organs and tissues, and thus
- 10:56precipitating the painful crisis.
- 10:58And hydroxyurea also helps cut down the level of inflammation in the
- 11:03body as well, because we've learned over time that sickle cell disease
- 11:07is a chronic inflammatory process.
- 11:09So if you address inflammation, you can address sickling and pain crises.
- 11:16And hydroxyurea as well helps keep the lining of the blood vessel itself
- 11:21healthier and thus also decreasing the incidence of blocking those
- 11:26blood vessels and causing the crisis.
- 11:30Another drug that's used is called Adakveo, and Adakveo is a medication
- 11:36that is administered by IV infusion.
- 11:40That is the patient will come into our clinic and get a monthly
- 11:45infusion of that medication.
- 11:47And what Adakveo does over time is that it reduces the painful crisis in
- 11:56terms of its severity and frequency.
- 11:59And say, if that person goes into the hospital, Adakveo has been shown to
- 12:05decrease the length of stay that that person has to stay in the hospital because
- 12:11it decreases the length of the crisis.
- 12:14It's given in the clinic and it's tolerated well by patients.
- 12:19Adakveo works by decreasing that stickiness that we talked about,
- 12:24that the blood cells experience prior to and after sickling.
- 12:31The third medication is Endari, and Endari actually is a powder.
- 12:38It's taken orally, taken twice a day and it too reduces the pain crises and reduces
- 12:44the incidence of something called acute chest syndrome, which mimics an infection.
- 12:50But it can be very severe in terms of debilitating and increasing the
- 12:56length of stay in the hospital.
- 12:58So, Endari addresses that.
- 13:00Endari also decreases the frequency of hospitalizations and the number of
- 13:05days stayed in the hospital as well.
- 13:08Melanie Cole, MS: Dr.
- 13:08Bell, can it ever be cured?
- 13:10Dr. Gary Bell:
- 13:10Well, the cure addresses a treatment, I think, that aims at permanently correcting
- 13:18or bypassing the underlying genetic defect in sickle cell disease rather
- 13:24than managing the symptoms, the painful crises, the hospitalizations, and such.
- 13:31And right now, there are two cures for sickle cell disease, and one is
- 13:38bone marrow or stem cell transplant.
- 13:42And bone marrow transplants is reserved for patients with more severe sickle cell
- 13:48disease but is also reserved for patients who are relatively healthy and don't have
- 13:55any of the long-term organ complications that can come from chronic sickle cell
- 14:01disease like kidney failure, chronic kidney disease, or pulmonary hypertension,
- 14:06which is an elevated blood pressure in your lungs that can cause a dependency
- 14:11on oxygen or congestive heart failure.
- 14:15So, you don't want to get sickle cell disease and allow it to progress
- 14:20till you have organ damage, which would put you out of contention for
- 14:26a possible bone marrow transplant.
- 14:28And with bone marrow transplant, of course, you need a donor.
- 14:33So, the ideal donor would be a sibling-matched donor.
- 14:37And, I think, less than 15% of the time, you find a sibling-matched donor.
- 14:45And the other curative therapy is gene therapy, where the patient's
- 14:50own stem cells are used to make new blood that's higher in fetal
- 14:56hemoglobin or anti-sticking hemoglobin.
- 15:00It's a very extensive process, gene therapy is, and it's also very expensive.
- 15:09So, you have those limitations when it comes to curative therapy when you talk
- 15:15about bone marrow and gene therapy.
- 15:18Melanie Cole, MS: That's so interesting.
- 15:20It's a very exciting time, Dr.
- 15:22Bell.
- 15:22That was great information.
- 15:24Thank you.
- 15:24Now, China, many people with sickle cell disease experience
- 15:29gaps in care when they transition from pediatric to adult medicine.
- 15:33Tell us a little bit about why you feel this happens and why it's so
- 15:37important to establish that ongoing care, that continuum of care with
- 15:42an adult sickle cell specialist.
- 15:45LaChina Hollis: So, yes, that's actually a great question, and there are a lot
- 15:48of studies that are out now that show that the transition from pediatric to
- 15:55adult care is a really high-risk period.
- 15:59And sickle cell disease is a disease that has to be managed lifelong.
- 16:04So, it means you have to have a continuity of care.
- 16:08So, a lot of patients become lost during this transition period
- 16:12because they come from a really highly coordinated pediatric system.
- 16:17Parents are involved, the appointments are scheduled, school accommodations
- 16:22are arranged in the pediatric setting.
- 16:25Oftentimes, you know, pediatric hematologists, they know the
- 16:29patient from top to bottom.
- 16:31They know the patient's history really well.
- 16:34And so, around adolescence, you lose some patients because the patients
- 16:40are growing up and they're less interested in healthcare at that point.
- 16:45And so, when the patients are transitioning to young adulthood,
- 16:49oftentimes they don't want as much care, they don't want as much involvement.
- 16:54So, we have to really have some good programming in place to keep up with
- 17:00their care and to force continuity.
- 17:02So often, there are other reasons for gaps that include the transfer from familiar
- 17:10pediatric teams to unfamiliar adult teams.
- 17:14And also, there's some difficulty in finding hematologists that have specific
- 17:20skill sets in sickle cell disease or expertise in sickle cell disease.
- 17:25And another big issue, that loss of parental involvement is
- 17:29huge because the patients become responsible for their own care.
- 17:35They become responsible for any changes in insurance, or they
- 17:40have losses in pediatric coverage.
- 17:43Sometimes transportation can be an issue or employment, or when they transition
- 17:49to college, finding programs that support sickle cell disease is hard.
- 17:55So, mental health, social challenges, those can also be some things that
- 18:00interfere with that transition.
- 18:03So, you did ask about why is it important to establish
- 18:06with a sickle cell specialist.
- 18:08It's really important because sickle cell disease is far more than just the
- 18:15management of an occasional pain crisis.
- 18:18It's really a lifelong multi-system disease that has so many complications,
- 18:24and these complications can accumulate even when our patients aren't
- 18:29going through sickle cell crisis.
- 18:31So, adult specialists can provide that continuity and proactively monitor for,
- 18:39you know, things like kidney disease or pulmonary hypertension, retinopathy,
- 18:44avascular necrosis, strokes, which are some of the things that can happen
- 18:49secondary to sickle cell disease.
- 18:52Melanie Cole, MS: Well, thank you for that.
- 18:53So, Dr.
- 18:53Bell, what can people do to manage the disease, reducing their risk of a crisis?
- 19:00Speak about some common triggers and really when you feel it's important
- 19:04that someone seek emergency care
- 19:07Dr. Gary Bell:
- 19:07Well, you know, here in the clinic, I think one of the things
- 19:11we stress is managing stress.
- 19:15That is avoiding anything or activity that puts the body under stress.
- 19:21And when the body is under stress, patients start to experience crisis.
- 19:27We begin to see the effect of that blocking of blood flow
- 19:32and oxygen to the organs.
- 19:35And as China said, the primary manifestation of that is pain.
- 19:41And some of the common triggers that we talk about all the
- 19:46time, temperature changes.
- 19:49You know, whether you're going from a warm environment into a cold
- 19:53environment, that's enough stress to cause blood cells to sickle.
- 19:59And we encourage patients to dress appropriately for conditions.
- 20:04And sometimes we don't think about this.
- 20:06Like, you can go into a restaurant on a day like today where the temperature
- 20:11is 95 outside, and you go into a restaurant where the temperature is
- 20:1575, and you don't have a sweater on.
- 20:19By the time you get home, if you're a sickle cell patient,
- 20:22you may go into crisis.
- 20:23So, we encourage patients to appropriately dress, both in the winter and the summer.
- 20:30One of the things that myself, as someone who doesn't have sickle
- 20:35cell disease, when you get on an airplane, they can freeze you out.
- 20:40And if you're not prepared for that, that can cause you to have
- 20:44a pretty long trip or spoil a vacation or something like that.
- 20:49Anything that lowers the level of oxygen in your blood, say if you are
- 20:54a young 15, 16-year-old who's playing high school sports, and you get out
- 20:59on the football field and overexert yourself, you may precipitate a crisis.
- 21:05I had a patient who recently went to Mexico and went into the mountains,
- 21:10and that precipitated a crisis because he wasn't prepared for the lower level
- 21:17of oxygen in the mountains, and his body reacted to that, and he went into
- 21:23crisis while he was out of the country.
- 21:25Another common thing that lowers oxygen levels can precipitate
- 21:31hospital admissions is an infection.
- 21:34So, we try to address infections quickly because it can lead to
- 21:42some devastating consequences.
- 21:43It can prolong hospitalizations.
- 21:45And if the infection is not treated appropriately, death could result.
- 21:50Another thing that we try to manage and trying to get better at addressing
- 21:56is anxiety and depression and emotional issues that can either be
- 22:02precipitated by the disease itself, because again, this is a chronic
- 22:06disease and not only is it chronic, but it manifests itself with pain.
- 22:12And someone in chronic pain has to deal with depressive symptoms.
- 22:17Life stressors in this community of patients can cause anxiety and depression.
- 22:24All of that affects the response of the body to that stress.
- 22:29That's why it's important that we in the clinic, we aggressively try to get
- 22:34these patients plugged into behavioral health programs so that we can remove
- 22:40that variable in terms of stress.
- 22:43Melanie Cole, MS: Well, thank you for that.
- 22:44I'd love to give you each a chance for a final thought here.
- 22:47So, Dr.
- 22:48Bell, I would like you to offer your best advice to patients about working
- 22:54with their physicians on some of those exciting treatments you were discussing,
- 22:59on trying to follow the course of the condition and really work with
- 23:05those multidisciplinary specialists so that they can get the best care.
- 23:10Dr. Gary Bell:
- 23:10Well, the thing to remember in all of this is that sickle cell
- 23:14disease is a chronic condition.
- 23:18And, you know, I reflect back 35 years ago, my brother
- 23:22succumbed to sickle cell disease.
- 23:25And back then, there was not the treatment modalities that we have today.
- 23:32You had dedicated physicians who addressed mainly pain.
- 23:37Now, we have different modalities that sickle cell specialists and, in
- 23:42some cases, primary care providers, can provide to these patients.
- 23:47But I think the important thing for our patients is to be
- 23:52educated about their disease.
- 23:54They know themselves better than we do.
- 23:57They know when something very subtle means something very
- 24:02big in terms of their health.
- 24:04So, getting other providers involved, whether it's the hematologist, whether
- 24:09it's physical therapist, whether it's behavioral therapist, it's a collaborative
- 24:15effort that in the end, when we're all working together as a team, we can have
- 24:20much better outcomes for our patients.
- 24:23Melanie Cole, MS: China, last word to you.
- 24:25I'd like you to speak now to the family members, the friends and
- 24:29caregivers that love these patients.
- 24:31How do they support someone living with sickle cell disease throughout their life?
- 24:36What would you like them to know about the help that's out there at Prisma Health for
- 24:41the entire family and the whole person?
- 24:44LaChina Hollis: It is really important for families to establish care with
- 24:49centers that are similar to the Lifespan Center that we have here at Prisma Health.
- 24:55So, it is exactly what it means.
- 24:58The Lifespan Center, we want to help patients as they age with
- 25:03sickle cell disease by forming that support system that they need.
- 25:07So, we're not there just for the patients, we're there for their families
- 25:12too, and providing education and having clinical staff to assist with community
- 25:18needs as well, connecting patients with community-based organizations just feeding
- 25:24into that support system that they need.
- 25:27Another thing is focusing on what the patient is actually going through.
- 25:33Believe the patient's pain.
- 25:35We often hear that with our patients that they don't feel as
- 25:38if they're heard or listened to.
- 25:40So, actually listening to our patients and meeting their needs, meeting our
- 25:44patients where they are, and helping them to manage sickle cell crisis,
- 25:49helping them to prevent sickle cell crisis, and helping them with their
- 25:54emergency plans and making our families aware of their emergency plans as well.
- 26:00So, just becoming an overall support system for our patients that are living
- 26:04with sickle cell disease is one of the most important things for our families,
- 26:09their friends, their caregivers, and their overall support system.
