According to Phyllis C. Zee, MD, PhD, proinflammatory cytokines influence neural processes that affect sleep and circadian rhythm. “It’s almost like when you’re most vulnerable, when you’re sleeping, the immune system is kind of poised for attack,” Dr. Zee, chief of the division of sleep medicine at Northwestern University, Chicago, said at the Revolutionizing Atopic Dermatitis symposium. “This is normal, and perhaps in some of these inflammatory disorders, it’s gone a little haywire.”
Circulation of interleukins and cytokines are high in the morning, become lower in the afternoon, and then get higher again in the evening hours and into the night during sleep, she continued. “Whereas if you look at something like blood flow, it increases on a diurnal basis,” she said. “It’s higher during the day and a little bit lower during the mid-day, and a little bit higher during the evening. That parallels changes in the sebum production of the skin and the transepidermal water loss, which has been implicated in some of the symptoms of AD. What’s curious about this is that the transdermal/epidermal water loss is really highest during the sleep period. Some of this is sleep gated, but some of this is circadian gated as well. There’s a bidirectional relationship between sleep and immunity.”
Disturbance of sleep can have multiple consequences. It can activate the hypothalamic-pituitary-adrenal axis through autonomic activation, increase brain metabolic activity, trigger mood disturbances and cognitive impairment, and cause daytime sleepiness and health consequences that affect cardiometabolic and immunologic health.
One study conducted by Anna B. Fishbein, MD, Dr. Zee, and colleagues at Northwestern examined the effects of sleep duration and sleep disruption and movements in 38 children with and without moderate to severe AD. It found that children with AD get about 1 hour less of sleep per night overall, compared with age-matched healthy controls. “It’s not so much difficulty falling asleep, but more difficulty staying asleep as determined by wake after sleep onset,” said Dr. Zee, who is also a professor of neurology at Northwestern.
A study of 34,613 adults who participated in the 2012 National Health and Nutrition Examination Survey found that eczema increased the odds of fatigue (odds ratio, 2.97), daytime sleepiness (OR, 2.66), and regular insomnia (OR, 2.36).
“Very importantly, it predicted poor health,” said Dr. Zee, who was one of the study’s coauthors. “This gives us an opportunity to think about how we can improve sleep to improve outcomes.”
Dr. Zee advises dermatologists and primary care clinicians to ask patients with AD about their sleep health by using a screening tool such as the self-reported STOP questionnaire, which consists of the following questions: “Do you snore loudly?” “Do you often feel tired, fatigued, or sleepy during daytime?” “Has anyone observed you stop breathing during your sleep?” “Do you have or are you being treated for high blood pressure?”
Other clinical indicators of a sleep disorder, such as obstructive sleep apnea (OSA), include having a neck circumference of 17 inches or greater in men and 16 inches or greater in women. “You want to also do a brief upper-airway examination, the Mallampati classification where you say to the patient, ‘open your mouth, don’t stick your mouth out too much,’ and you look at how crowded the upper airway is,” Dr. Zee said . “Someone with a Mallampati score of 3 has a very high risk of having sleep apnea.”
She also recommends asking patients with AD if they have difficulty falling asleep or staying asleep 3 or more nights per week, and about the frequency and duration of awakenings. “Maybe they have insomnia as a disorder,” she said. “If they have trouble falling asleep, maybe they have a circadian rhythm disorder. You want to ask about snoring, choking, and stop breathing episodes, because those are symptoms of sleep apnea. You want to ask about itch, uncomfortable sensations in the limbs during sleep or while trying to get to sleep, because that may be something like restless legs syndrome. Sleep disorder assessment is important because it impair daytime function, cognition, attention, and disruptive behavior, especially in children.”
For the management of insomnia, try behavioral approaches first. “You don’t want to try medications from the get-go,” Dr. Zee advised. Techniques include sleep hygiene and stimulus control therapy, “to make the bedroom a safe place to sleep. Lower the temperature a little bit and get rid of the allergens as much as possible. Relaxation and cognitive-behavioral therapy can also help. If you get a lot of light during the day, structure your physical activity, and watch what and when you eat.”
An OSA diagnosis requires evaluation of objective information from a sleep study. Common treatments of mild to moderate OSA include nasal continuous positive airway pressure and oral appliances.
Dr. Zee disclosed that she had received research funding from the National Institutes of Health, Jazz Pharmaceuticals, Harmony and Apnimed. She also serves on the scientific advisory board of Eisai, Jazz, CVS-Caremark, Takeda, and Sanofi-Aventis, and holds stock in Teva.
