Medical Research: What is the background for this study?

Prof. Chang: Sleep disturbance is a common disorder in the children with atopic dermatitis (AD) (reported in 47 to 60%), but no effective way of managing this problem had been established. In our preceding study, we found that lower nocturnal melatonin level was significantly associated with sleep disturbance in the patients with AD. Melatonin is a hormone secreted by the pineal gland which plays an important role in sleep regulation. In addition to sleep-inducing effects, melatonin also has anti-inflammatory and immunomodulatory properties which might be helpful for the management o fatopic dermatitis. Furthermore, melatonin has an excellent safety profile with minimal adverse effects, making it a good choice for children. Therefore, we aimed to evaluate whether melatonin is effective for improving the sleep problems and the dermatitis severity in children with atopic dermatitis.

Medical Research: What are the main findings?

Prof. Chang: From our double-blind, placebo-controlled crossover study, we found that after melatonin treatment, the sleep onset latency shortened by 21.4 minutes compared with placebo (from a mean of 44.9 minutes to 21.6 minutes). The Scoring Atopic Dermatitis Index (higher scores representing more severe dermatitis) also decreased by 9.9 compared with placebo (from a mean of 49.1 to 40.2). No adverse events were reported throughout the study.


Medical Research: What should clinicians and patients take away from your report?

Prof. Chang: Melatonin supplementation both shortened the sleep-onset latency and improved the dermatitis severity in children with atopic dermatitis, therefore it could be very helpful for the management of children with AD and sleep problems, especially those who have difficulty falling asleep. Although melatonin is available over the counter in many parts of the world, we would recommend parents to discuss with a doctor before putting kids with  atopic dermatitis on melatonin. We would also like to remind parents that while melatonin might be helpful, adequate control of the dermatitis (with their medication and moisturizers) is still crucial if they want to improve their child’s sleep problems.

Medical Research: What recommendations do you have for future research as a result of this study?

Prof. Chang: Further studies are needed to find the optimal dose and duration of melatonin treatment for patients with atopic dermatitis. It would also be interesting to know if melatonin is also helpful for patients with sleep disturbance due to other allergic diseases (such as asthma and allergic rhinitis).
