New hope for sleep apnea sufferers

The best help for a growing sleep problem

Like an estimated seven million Canadians, though most will never know it, Egidia Rovinelli suffers from obstructive sleep apnea. “I’d wake up, my head hurting and my throat dry, feeling like I was in a fog,” recalls the 61-year-old retired travel agent from Mississauga, Ont. Without treatment, Rovinelli’s airway relaxes and closes during sleep, causing her to stop breathing about 50 times per hour. Sleep apnea is an anatomical problem of the upper airway that causes it to briefly close. Sufferers may wake up gasping for air, or they may not; the passage eventually opens again. “It’s not how many times you wake up, it’s how many times you stop breathing,” explains Charles Samuels, medical director of the Centre for Sleep and Human Performance in Calgary.

Overweight and chronically ill, Rovinelli was eventually diagnosed with severe apnea, a condition she’s likely had for years.  Since apnea is now associated with heart disease, high blood pressure and diabetes, Rovinelli was promptly prescribed conventional continuous positive airway pressure (CPAP) therapy—a mask and machine that blow pressurized air into the airway. She immediately nicknamed her machine Fred.

Despite the name, Fred wasn’t cute. “The more I used Fred, the more I hated him,” she says. Besides making her uncomfortable and claustrophobic, the machine was terrible for travel, which Rovinelli does often. She worried about the effect on her romantic life. Single and dating, she doesn’t want Fred in her bed. “You meet someone new, bring him home and put this thing on? I don’t think so.”

“The CPAP works very well—if people use it,” says Samuels. Compliance, however, is proving difficult. Though apnea is often associated with older overweight men, increased awareness and a rising obesity rate mean young people and women are now being tested and diagnosed. Few are keen on the cumbersome machine.

“Therein lies the interest in other, more agreeable therapies,” says Sachin R. Pendharkar, a sleep researcher at the University of Calgary, who specializes in alternative apnea treatments. Some have been around for a while. Custom-made dental devices pull the lower jaw forward to open the airway. New gadgets include Night Shift, a product worn on the back of the neck that vibrates when a user rolls onto their back (which causes snoring and aggravates apnea). Others are enterprising variations of old tricks: a tennis ball sewn into a shirt, for example, which shifts sleepers off their backs, is now available online for $19 as the Tennis Ball T-Shirt.

But what’s really making waves is Provent, a system of disposable Band-Aid-like adhesives that stick over each nostril. “They have a one-way valve for airflow, so you can breathe in through your nose, but as you breathe out, increased resistance generates a back pressure that keeps the airway open,” says Pendharkar, who gave a talk on the product at the 2013 Canadian Respiratory Conference in April. The verdict has been mixed: Provent claims its therapy will work for 81 per cent of patients. Clinical tests from the NYU School of Medicine found Provent’s efficacy rate was high, especially for women, but a randomized trial out of Zurich found no difference between Provent and a placebo.

Then there’s a familiar problem: applying it to the real world. For some, Provent works like a charm. It’s discreet, portable and relatively inexpensive. CPAPs sell for $1,000 to $2,500, but are partially covered by some provincial plans; Provent runs about $3 a pop, but isn’t.

Some worry Provent could soon join the sleep apnea treatments featured in late-night infomercials. “I cringe when I see those,” says Pendharkar. Apnea symptoms like fatigue, headaches or weight gain could indicate any number of problems, so proper diagnosis is imperative. “People instead do sleep studies online,” says Samuels. “They self-diagnose; they spend money on gadgets that don’t work.”

As the gadget war continues, lifestyle factors—weight loss, avoiding alcohol and sedatives, exercising—are largely ignored. That’s too bad. “Sometimes when patients get healthier,” says Pendharkar, “they don’t need treatment at all.”


 

New hope for sleep apnea sufferers

  1. We have had, of course, a huge rise in night-time deaths?

    • You sound hopeful.

      • Another fake illness.

        • And you have no clue what you’re talking about. None.
          Overdiagnosed? Quite possibly. It’s been shown that some sleep disorder clinics have diagnosed it in over 90% of their patients, including those who don’t have it, and even some who insist they stayed wide awake all night, which should have made it impossible to detect, even if they did have it! This is especially true in the US where the clinic then has the chance to earn revenue from selling CPAP machines. So overdiagnised? Sure. But also underdiagnosed in many thousands who have it and don’t realize it. It is very real for many sufferers. If you’ve ever heard the loud snoring and constant choking/gagging of someone suffering with this (I have), then seen the difference a CPAP can make (again, I have) you’d understand why it’s such a problem, and why they can never get a restful night’s sleep. What is your personal experience? Or do you have any?

          • Show me the death count.

            Otherwise….roll over.

          • I’ll get the puppets.

          • It probaly results in increased heart attacks which are more common in earlymorning and also people who don’t wake up. They would not be classiefied as sleep apnea deaths.

          • We haven’t had any increase in deaths…middle of the night or otherwise.

  2. No night-time deaths, unless you count heart disease, which is the second-leading cause of death in the country so you probably should.

  3. EmilyOne. You have to comment on everything. I think you need to get out of the house and have an actual life.

  4. Turn on the CPAC channel and watch PhDs in say a lot and mean so very little types a talking. Even if you have interest in the subject, the repetition will bore your right to sleep.
