Ultraviolet (UVA and UVB) Light Therapy in the Treatment of Inflammatory Skin Conditions

Stopped early · Phase 1/Phase 2

Conditions studied: Atopic Dermatitis, Psoriasis, Alopecia, Mycosis Fungoides, Urticaria, Dermatoses, Stretch Marks

In brief

The purpose of this investigation is to study the effectiveness of longer wavelength UVA1 (340-400nm) or shorter wavelength ultraviolet B \[UVB\] (290-320nm) irradiation in the treatment of inflammatory skin conditions (such as: atopic dermatitis, psoriasis, mycosis fungoides, alopecia areata, stretch marks and urticaria). This research study aims to evaluate the effectiveness of an investigational device which is similar in appearance to a "tanning bed" but which emits ultraviolet irradiation of a specific wavelength known as UVA1. This device has not been approved by the Food and Drug Administration (FDA) for general use in this country, as of yet, but it has been used quite successfully in Europe for several years in treating such conditions as scleroderma, atopic dermatitis, urticaria pigmentosa and other skin conditions. Instead of UVA1 therapy, patients may receive ultraviolet radiation of a specific wavelength known as UVB. UVA1 light is a longer wavelength and therefore a lower energy wavelength than UVB. UVB light is often the light associated with getting a sunburn since it has a higher level of energy. UVB light has been used successfully in the treatment of many skin conditions.
