Young Patients Bond Over Shared Blood Disorder, Treatment at Rady Children’s
Ella Martinez and Kamila Saradpon consider each other sisters. They hang out together, laugh, share secrets, and play games. They even went to school together for a time. They celebrate each other’s wins and encourage each other to keep going during tough times, as sisters do. And though they’re not genetically related, they are bound by blood.
Both girls live with thalassemia, a rare genetic blood disorder that hinders the body’s production of hemoglobin, a component of red blood cells responsible for carrying oxygen to other cells. There are different types of thalassemia, and they can range in severity from asymptomatic or mild anemia to serious health problems, including an enlarged spleen, iron overload, and bone deformities. The most severe types require frequent blood transfusions, likely for life. Kamila and Ella both require transfusions—Ella every two weeks and Kamila every three. Both girls receive transfusions at the Peckham Center for Cancer and Blood Disorders at Rady Children’s, which, coincidentally, is what brought the best buddies together in the first place.
And Then There Were Two
Ella’s mom, Erica, had never heard the word “thalassemia” until she became pregnant with now 16-year-old Ella and her twin brother. The children’s father mentioned that he was a carrier for the condition.
“At the time, I had no idea what that meant,” she says.
Her doctor explained that some people carry the thalassemia trait, but it was uncommon. And even if she and Ella’s father were carriers, it was unlikely they’d be carrying genes for the same type. Plus, even if they both had the same type, which genetic testing later revealed that they did, there was still just a 1 in 4 chance that the child would develop thalassemia.
The twins’ newborn screenings indicated that neither child had thalassemia, but at Ella’s four-month check-in, her pediatrician noticed that her hemoglobin count was low. At 6 months, Ella was referred to a hematologist at Rady Children’s and was diagnosed with a severe form of thalassemia. She had her first blood transfusion three months later.
Then, Erica realized just how rare transfusion-dependent thalassemia was. More than a million people around the world have thalassemia, with about a tenth of those being transfusion-dependent. Many are in regions where the condition is more common—Mediterranean countries, like Greece and Turkey, as well as in Asia, Africa, and the Middle East. In the U.S., it’s estimated that 1,000 to 1,500 people have transfusion-dependent thalassemia. Even fewer of those are pediatric patients, and fewer still live in the San Diego area.
“It seemed like nobody knew about thalassemia.
I was always asking the hospital, ‘Is there anybody else?’
I felt like when I first started with her, there was a lot that
I didn’t know,” Erica says.
When Ella was 6, her family was introduced to the Saradpons. Kamila, now 10, was just a baby, but the girls had an immediate connection.
“We agreed to meet at one of Ella’s blood transfusions. It was really emotional to see someone looking completely normal and beautiful getting a blood transfusion just like my baby gets blood,” says Kamila’s mom, Maria. “We sat Kamila down on the bed, and Ella was playing with her right away. She gave her a little toy that she had gotten at McDonald’s. Ella had a Happy Meal, and Kamila was drooling over the toy that came with it. That’s a core memory for sure.”
Maria and Erica learned they had a lot in common, too.
Like Erica, Maria found out she carried the trait for thalassemia while pregnant, never having heard the word “thalassemia” before. Maria’s husband, Kris, was found to be a carrier, too, and, just as Erica experienced during her pregnancy, the couple was told the chances were slim that they carried the same type. Even after further testing revealed Kris and Maria did carry compatible traits for thalassemia, odds were still in favor that Kamila wouldn’t be affected.
“We scheduled a meeting with a genetic counselor because I had questions about what life with thalassemia would look like if Kamila were to have it. We didn’t know anyone who had this blood disorder,” Maria says. “Unfortunately, the genetic counselor was only able to discuss the likelihood of Kamila inheriting thalassemia from us, 1 in 4, and not any specifics about the disease.”
When Kamila was born, her newborn screening results revealed an intermediate form of thalassemia, and she was referred to a hematologist at Rady Children’s. Kris and Maria started taking Kamila in for labs there every couple of weeks, holding on to hope that she wouldn’t require blood transfusions. While initial blood tests were normal, a routine check just a few weeks later revealed a different story. Kamila needed an urgent blood transfusion at only 2 months old.
“My heart sank when they mentioned needing a blood transfusion,
but I could tell right away that it made a huge difference for Kamila.
She seemed so much stronger, nursed better, and was more energetic
after just one. Even though it was scary and unsettling watching our
baby receive blood at such a young age, it was such a relief to see her
feeling better,” says Maria.

Ella and Kamila developed a bond quickly.
A Place Just for Them
Both girls are patients of the Comprehensive Thalassemia Center at Rady Children’s and UC San Diego. Its multidisciplinary team sees about 90 kids from Southern California, though only around 10, including Ella and Kamila, require blood transfusions at varying frequencies.
Some people with severe forms of thalassemia, like the types Ella and Kamila have, need regular blood transfusions to replenish their red blood cells. People with less severe forms may need an occasional blood transfusion, for instance when they’re sick or have an infection. Transfusion-dependent thalassemia patients also must take medication to remove the extra iron from their bodies.
“There are certain types of thalassemia that would predispose a person to need transfusions for their whole life. Ella has beta thalassemia major, which is the most severe form of beta thalassemia, and Kamila has hemoglobin E beta thalassemia, which is also severe,” says Jennifer Yu, MD, medical director of the Comprehensive Thalassemia Center and associate clinical professor at UC San Diego School of Medicine.
For Ella and Kamila, transfusions have become just a part of life. As young as age 3, Ella could tell when she was due.
“Ella would tell me to call the doctors and tell them that she needs blood,” her mom says. “I would call my case manager, and she’d tell me to bring her in for labs. And every time Ella told me she needed blood, she needed blood. I learned at a really young age to listen to what she says because she’s so in tune with her body.”
A transfusion appointment takes four to six hours. Ella and Kamila schedule transfusions at the same time when possible. Each appointment starts with lab work, then center personnel contact the San Diego Blood Bank for matched blood.
“We have a very specific blood volume calculator that we use. It’s the formula that tells us, based on their hemoglobin at the time and their weight, what volume they need to get to an ideal hemoglobin level,” says Dr. Yu. “Every time we order blood, we order it on the day of so we can get exactly what they need.”

The girls schedule their transfusions at the same time to support each other.
Both families say they appreciate that Dr. Yu and the rest of the clinic staff always listen to their concerns and respond with compassion and understanding. And when the girls are without each other’s company, hospital doctors, nurses, and child life specialists find ways to make their appointments comfortable and more fun. Kamila even calls Rady Children’s her favorite place.
“She’s treated like royalty at Rady Children’s—I’m not joking
when I say that her favorite place to be is there in that bed with
a nurse pampering her and doting on anything she does,” says Maria.
“She loves it there and looks forward to her transfusions.”
