Flipping the model presents a new way to treat sleep apnoea

New Australian research that flips an existing therapy model will introduce a whole new way of treating sleep apnoea.

The research team at the Adelaide Institute for Sleep Health: Flinders Health and Medical Research Institute Sleep Health Research Program, has examined shortcomings in some people’s response to the popular Continuous Positive Airway Pressure machine (CPAP) and found that adding combinations of therapies gets impressive results in those who are unable to tolerate CPAP.

Oral appliance therapy (OAT) is an effective treatment for many people with obstructive sleep apnoea (OSA) but does not fully control OSA in about 50 per cent of cases.

This study—published in the Annals of the American Thoracic Society—aimed to control OSA in individuals who have an incomplete response to using only OAT, with the solution being to use additional targeted therapies informed by each individual’s specific causes of OSA known as ‘endotype’ characterisation.

“Rather than everyone first trying CPAP—for whom we know at least 50 per cent will fail—we flipped the model on its head and gave everyone a dental split in the first instance,” Professor Danny Eckert said. 

“This tends to be much better tolerated than CPAP, though it is less efficacious overall, as it works in about 50 per cent of people. 

“However, we found that if the dental device alone was insufficient, we added extra treatments—and this combination of therapies fixed almost all the 50 per cent of the remaining patients.” 

The team then added alternate and emerging therapies such as oxygen therapy, and novel medications informed by the findings of a detailed sleep study they did that told them exactly why each person developed OSA.

“If this combination approach didn’t fully work, we then gave CPAP, but only as a last resort,” Professor Eckert said.

“Using this new approach, we were able to treat almost all participants and only a few required CPAP. Essentially, we believe this outlines a whole new way of treating sleep apnoea.”
