The Current19:21A genetic disease killed Ayla’s sisters. A first-of-its-kind treatment is helping her survive
Ayla Bashir acts like the common 17-month-old would. She’s making sounds, shifting her limbs round, and grabbing at objects close by.
These are milestones her mother and father, Sobia Qureshi and Zahid Bashir, weren’t certain she’d attain when she was recognized with Pompe disease — the identical genetic situation that had killed two of her sisters.
“When she began crawling or strolling or saying her first few phrases, and so on., you take a look at it and you are like, OK, she’s actually a miracle,” Zahid informed The Current‘s Matt Galloway.
The Ottawa-born toddler is a singular case on this planet of treatment for Pompe disease, a uncommon and sometimes deadly disease that disables the center and skeletal muscle mass.
While most infants with the disease are handled within the months after their delivery, Ayla was the primary little one on this planet to be handled in-utero, in accordance with Children’s Hospital of Eastern Ontario (CHEO) in Ottawa.
The protocol was developed on the University of California San Francisco, and concerned six prenatal enzyme alternative remedies on the Ottawa Hospital whereas Ayla was within the womb.
“We have been very lucky that we have been in a position to begin treatment in utero after I was 24 weeks pregnant,” Qureshi informed Galloway. “Because of that, she has not had any signs of Pompe up to now.”
Dr. Pranesh Chakraborty, the household’s long-time physician, helped carry the treatment to Ottawa from UCSF, the place it was presupposed to be accomplished initially.
He co-led a case examine about Ayla and her treatment, which was printed within the New England Journal of Medicine on Wednesday.
“I at all times really feel an enormous sense of duty every time we’re caring for households like Ayla’s,” he informed Galloway.

The growth is being well-received different medical professionals. McMaster University’s Dr. Mark Tarnopolsky, one in all Canada’s main Pompe disease specialists, referred to as it an “thrilling growth.”
“I’m an enormous fan,” the uncommon disease specialist informed The Current.
“Clearly, we knew the sooner you deal with, the higher. And I assumed, ‘Wow, this is the final word in early treatment.'”
Entering ‘miracle territory’
According to Chakraborty, Ayla’s progress began not when she was within the womb, however with her sisters, Zara and Sara, who each died from Pompe disease, at 2.5 years and eight months, respectively.
“If I replicate again with Zara … and the trail we walked at the moment, and the trail we walked with Sara via the palliative care, you already know, these have been onerous and troublesome components,” he mentioned. “But to me, this is a continuation of that very same journey, hopefully with a a lot, significantly better final result.”
The couple, who even have a son and daughter with out Pompe disease, discovered somewhat extra concerning the treatment course of with every little one recognized, in accordance with Qureshi. After Zara’s loss of life in 2011, the couple began having prenatal testing accomplished for every little one. They went into palliative care when Qureshi was pregnant with Sara in 2016.
So after they visited Chakraborty throughout Ayla’s being pregnant, Qureshi mentioned that they had hoped for a growth in childish Pompe disease.
“With this being pregnant, they actually have been eager to deal with her as aggressively as potential, and provides Ayla pretty much as good and as finest likelihood as potential that she may have,” Chakraborty mentioned. “And we wished to facilitate that.”
Chakraborty mentioned he reached out to Dr. Priya Kishnani, division chief of Medical Genetics at Duke University.
She in flip led him to researchers at UCSF, who have been ” what wouldn’t it take to begin treatment when the injury is being accomplished, which is in fetal life,” Chakraborty mentioned.
Zahid mentioned he and Qureshi have been then on a name with a number of members of the medical group, from UCSF, Duke and the Ottawa Hospital, speaking concerning the potentialities of Ayla getting in-utero treatment.
“But … that concerned Sobia and Ayla having to journey to the U.S., you already know, nonetheless elbow-deep within the pandemic and having to get the infusions there,” he mentioned.
“And we walked away from that decision, I’d say, type of unhappy as a result of we realized that there [were] simply too many hurdles.”
This is the place Ayla’s story entered “miracle territory,” Zahid mentioned. Following that preliminary name in late 2020, Zahid and Qureshi discovered that the medical specialists had continued discussing shifting the treatment to Ottawa — they usually have been going to observe via with it.

Chakraborty mentioned it was via discussions with Ottawa Hospital’s Dr. Karen Fung-Kee-Fung that they realized there have been a few the explanation why they may do it in Ottawa as an alternative.
“One is the process for really accessing the fetal circulation, accessing the fetal blood and infusing treatment, is one thing that is been accomplished for the reason that Eighties,” he mentioned. “So the process was one thing that she had a variety of expertise with.”
“The treatment was additionally a typical treatment for Pompe disease, and it was one which we administer right here to youngsters with Pompe disease. But it was given via that particular process to entry the fetal circulation.”
With the method moved to Ottawa, Qureshi and Zahid have been in a position to get the required treatment for Ayla.
“This complete expertise has been a whirlwind,” Zahid mentioned. “But … we have now been so lucky to work with all of the people who we have been working with as a result of they really made it occur once we although it would not occur.”
‘The finest instance I’ve ever heard’
According to Tarnopolski, the uncommon disease skilled at McMaster, one of many key benefits this treatment has in comparison with others is timing.
“We prefer to deal with early, as a result of when you get injury to the muscle of each the center diaphragm and your skeletal muscle, it’s totally troublesome to reverse that, so that you’re just about simply saving what you could have,” he mentioned.
“So this is the very best instance I’ve ever heard and really fairly an ingenious method of giving pre-symptomatic treatment to a disease that progresses very quickly within the first few months of life.”
There’s additionally the problem of what is generally known as unfavorable immunogenic responses, which Tarnopolski says this treatment helps keep away from.
“When you infuse a protein into somebody, that causes an immunological response,” he mentioned. “So in utero, you are extra immunologically privileged, for lack of a greater time period, and you do not mount the identical immune response.”
“Therefore, there can be much less final buildup of antibodies, which might negate or attenuate the advantages of the enzyme alternative remedy.”
Despite that “double bonus,” Tarnopolsky mentioned the treatment is going to be troublesome to copy once more.
“It’s such a uncommon situation, that so many issues got here collectively to permit them to truly have the ability to give this to somebody in utero versus whenever you’re born, then you definately get recognized,” he mentioned.
“It’s solely going to be out there for a really uncommon set of circumstances, the place mother and father know that they are carriers — and the one method you are going to know you are a provider is in case you’ve had a toddler … and then you definately would have been examined.”
The treatment, like different fetal interventions, carries the chance of preterm supply, the examine famous.
Tarnopolsky mentioned he is excited to see how Ayla develops, and really completely happy for the household.
As for Qureshi, she simply hopes the treatment continues working correctly — and her daughter will get the possibility to develop up like another little one.
“I actually hope that she has a cheerful and wholesome and really fulfilling life, and that Pompe doesn’t turn out to be a barrier for her in any method,” she mentioned.
