Okate Dougherty pairs all of her son Elliot’s physician’s appointments with a deal with, like a visit to his favourite lunch spot or knowledgeable bull using present — certainly one of Elliot’s favourite sports activities, proper behind baseball and basketball. So after they flew from Missouri to Boston in 2018 for Elliot to have a brand new system implanted into his chest to deal with his sleep apnea, the deal with needed to be huge. Three days after the surgical procedure, Elliot was at his first Pink Sox recreation.
Since then, “it’s been a miracle,” his mom mentioned.
13-year-old Elliot, who has Down syndrome, has handled obstructive sleep apnea for his whole life. The problem — which occurs when somebody can’t get sufficient oxygen whereas asleep — affects about 80% of individuals with Down syndrome and might result in mind fog, ADHD-like signs, and a bunch of different points. The issues can usually be written off as “oh that’s simply Down syndrome,” Dougherty mentioned. “However there is no such thing as a ‘that’s simply Down syndrome.”

Elliot acquired the implant as a part of a Section 1 medical trial, the outcomes of which had been printed Thursday in JAMA Otolaryngology — Head & Neck Surgical procedure.
For youths with sleep apnea, the primary line of therapy is to take away the tonsils and adenoids. Elliot did this at 4 years outdated, and his mom mentioned it labored for a short while. However the sleep apnea got here again in full pressure, because it does for a lot of youngsters with Down syndrome who are inclined to have greater tongues and decrease muscle tone. The following therapy choice is a CPAP machine, which makes use of a face masks to maintain an individual’s air strain regular whereas they sleep. However youngsters with Down syndrome even have sensory points or really feel fidgety, and lots of are unable to put on the masks for these or different causes.

The choices are restricted after that. Some individuals have surgical procedure to cut back their tongue dimension and create area within the airway, however Dougherty didn’t wish to resort to that for Elliot.
At a convention on Down syndrome, she heard a couple of new examine to check a tool known as a hypoglossal nerve stimulator. It’s like a pacemaker, implanted within the chest with a direct line to the tongue. The system — turned on within the evenings utilizing a distant management — stimulates a nerve to maneuver the tongue all through the evening, opening the affected person’s airway.
The know-how, developed by the Minneapolis-based firm Encourage, earned FDA approval in 2020 for adults with sleep apnea. When pediatric ear, nostril, and throat doctor Christopher Hartnick noticed the primary examine of the system on adults, he realized it might doubtlessly assist youngsters with Down syndrome.
“I went to the oldsters at Encourage and I turned that pesky pediatrician who known as many, many occasions to say I’ve this inhabitants in want,” mentioned Hartnick, who practices at Massachusetts Eye and Ear.
In 2015, Hartnick and physicians at 4 different establishments across the nation started a medical trial in testing the system in 42 youngsters with Down syndrome and extreme sleep apnea, together with Elliot.
As a result of it was a Section 1 examine, the first objective was to make sure the implant was secure. Out of 42 kids, there have been few problems — the most typical facet impact was tongue or mouth discomfort, which occurred in 5 kids. However the early outcomes on efficacy had been additionally encouraging. Researchers tracked the change in apnea-hypopnea index, or the variety of occasions per hour when somebody isn’t receiving a ample quantity of oxygen whereas asleep. On common, the system helped sufferers to have about 50% fewer of those occasions per hour. For 3-quarters of sufferers, the variety of occasions dropped underneath the edge for extreme sleep apnea, which is 10 episodes or extra per evening.
For Dougherty, the change in Elliot’s high quality of life was clear. Elliot, who underwent the process at age 10, can keep up late at sleepovers and skip daytime naps, which he by no means might earlier than. He doesn’t get in bother in school like he used to, can focus higher, and has seen his speech skills enhance.
“As soon as we had been capable of get the sleep apnea underneath management, the entire different items started to fall collectively,” Dougherty mentioned. “I simply can’t think about how a lot better life would have been for Elliot if we might have carried out this sooner.”
Kishore Vellody, director of the Down syndrome Heart at UPMC Youngsters’s Hospital of Pittsburgh, mentioned that whereas the examine solely included a small variety of sufferers, he finds the analysis promising.
“Hopefully, as they add numbers, we begin to see extra of an impact that’s sustained even in bigger populations,” mentioned Vellody, who wasn’t concerned within the analysis.
The researchers are planning additional research on the system, significantly round its potential to enhance speech for a affected person with Down syndrome. The groups discovered that many sufferers like Elliot developed improved speech capabilities after the implant, maybe as a result of elevated use of their tongues at evening.
For the system for use extra broadly in kids with Down syndrome, it could have to earn FDA approval.
Tim Herbert, the CEO of Encourage, mentioned that the corporate is working instantly with the FDA to find out which avenue for approval will work greatest. The corporate is all for a broad pediatric approval, however has not mentioned if it plans to first search approval just for kids with Down syndrome. Hartnick mentioned that if the corporate set their sights on approval for the broader, and maybe extra worthwhile normal pediatric inhabitants, somewhat than solely on youngsters with Down syndrome, it is going to require extra analysis — and thus, extra time to attend for households.
“This will likely look like a small market to you, but it surely’s a fairly essential market and it’s representational, and if we now have to stroll earlier than we run — that’s actually the dialogue that we’re part of,” he mentioned.
The Dougherty household is grateful for the change the system has introduced into Elliot’s life. He turns it on by himself each evening, and off within the mornings. When requested what he remembers about getting the implant in Boston, Elliot mentioned, “it was superior.”
