What's New in Eczema (atopic dermatitis)

What's new in Eczema (atopic dermatitis)

There have been helpful pediatric (less than age 18) studies of patients with eczema (atopic dermatitis), ie sensitive skin. The parents of pediatric patients often ask what non-prescription products can improve their child’s itching. While I almost always review gentle skin care products, studies have shown that oral melatonin can be helpful with a “really safe” safety profile. This is because patients with itchy skin often have difficulty falling asleep. This may result in additional time scratching while in bed, less healing time while asleep, and potential increased itching during the daytime due to being less well rested.

A recent study showed that the worse the skin was doing, the worse the sleep disturbances. Studies have varied in showing whether patients with sensitive skin have decreased or increased melatonin. However, a study of 72 pediatric patients with atopic dermatitis by Chang et al showed that increased melatonin levels are correlated with improved sleep efficiency. Then a follow-up randomized clinical trial of 73 pediatric patients (age ranging from 1.8 to 17 yrs, median 7 yrs) also by Chang et al found that melatonin 3 mg/day improved their atopic dermatitis by about 20% (as defined by a scoring system called SCORAD) and the onset of sleep occurred about 20 minutes faster. No adverse events were reported.

Melatonin has traditionally been used to manage insomnia and jet lag. It seems to have “immunomodulatory, anti-inflammatory, and antioxidative effects, which might improve the skin inflammation.”

Safety-wise, melatonin is overall considered quite safe. A British Medical Journal publication stating “17 randomised [sic] controlled trials with 651 participants showed no evidence of adverse effects of melatonin with short term use (three months or less).” The study by Chang et al above used a 4 week timeframe which I consider reasonable given the evidence we have so far. There is no evidence I am aware of to guide how often this 4 week timeframe can be repeated and would be up to the treating physician’s experience and intuition. Studies of melatonin have included both pediatric and adult studies. However, the youngest patient treated in the study above was 1.8 years of age.

If you have eczema, itchy skin, or other skin issues, please make an appointment for dermatology consultation at (626) 331-6411 to discuss your options.
