Modern Aspects of Phototherapy for Atopic Dermatitis

Abstract EN

Phototherapy has still great importance in the treatment of atopic dermatitis, though costs, compliance, and long-term risks narrow its relevance.

In spite of its long history, up to now, the therapeutic regimes are mostly empirical.

Narrowband UVB und UVA1 are the most frequently applied regimens in atopic dermatitis with proven efficacy.

However, even for these modalities randomized prospective and controlled studies are still pending.

Advances in photoimmunology and molecular biology had demonstrated that phototherapy targets inflammatory cells, alters cytokine production, and has a significant antimicrobial effect within atopic skin.

This paper summarizes the current literature on the different regimes of phototherapy and also discusses therapeutic modalities like photochemotherapy and extracorporeal photopheresis.

These more complex regimes should be restricted to severe cases of atopic dermatitis, which are refractory to topical treatment.
