Nonpharmaceutical therapies offer alternatives for atopic dermatitis


 

EXPERT ANALYSIS FROM SUMMER AAD 2018

Anti-inflammatories

Cryotherapy is a potential anti-inflammatory, nonpharmaceutical treatment worth exploring, Dr. Lio said. It’s not exactly clear how or why cryotherapy works, but there are several possibilities: Very cold air may increase the body’s antioxidative capacity or reduce the conduction velocity of peripheral nerves, or the cold may simply relieve itch through local or systemic anti-inflammatory effects. At the same time, treatment-related adverse effects from whole-body cryotherapy are a risk – particularly frostbite, Dr. Lio said.

Vitamin D “is a bit of a controversial topic,” Dr. Lio said. The research has gone up and down supporting its potential benefits, so Dr. Lio errs on the side of recommending it.

“It’s one of those things I just give to everybody,” he said, adding that the risk-benefit ratio makes vitamin D worth trying as adverse events are unlikely.

Antipruritics

Dr. Lio discussed the fourth point of the tetrahedron: anti-itching agents. Much has been tried – antihistamines, various topical agents (camphor, menthol, pramoxine), antidepressants, gabapentin, antipsychotics – but little has panned out from these medications.

One study found significantly less refractory uremic pruritus at 1 and 3 months after receiving acupressure.

Hypnosis and biofeedback appear worthwhile as well, perhaps via stress relief. Stress and sleep deprivation can worsen atopic dermatitis and slow healing of the skin barrier. Some research has found subjective and objective benefits from hypnosis.

Dr. Lio endorsed a “write it down” approach when managing atopic dermatitis patients. An Eczema Action Plan, clearly written and provided to the patient, can reduce anxiety levels and increase understanding of the treatment regimens and their risks and benefits.

Dr. Lio has received honoraria for speaking and/or consulting from Pierre-Fabre, L’Oreal, Regeneron, Sanofi Genzyme, Pfizer, Theraplex, Johnson & Johnson, AbbVie, Eli Lilly, Exeltis, Franklin BioScience, Galderma, Kiniksa Pharmaceuticals, Menlo Therapeutics, and Mission Pharmacal. He has also received research grants from Pierre-Fabre and AOBiome.
