Low dose versus medium dose UV-A1 treatment in severe atopic eczema.
Twenty-two patients with severe atopic eczema were included in a therapy study with UV-A1 (wavelengths > 340 nm) treatment. The patients were divided into two dose groups, each consisting of 11 patients. One group received 10 J/cm2 and the other 50 J/cm2 five times a week for 3 consecutive weeks. No topical or systemical steroids or antihistamines were allowed. Using the SCORAD index as a measure of disease activity before onset of therapy and after 10 and 15 treatments, we observed a significant improvement in both dose groups after 15 treatments (10 J/cm2: p < 0.05, 50 J/cm2: p < 0.005). After 10 treatments only the improvement in the 50 J/cm2 group was significant (p < 0.005); the difference between the two dose groups was significant (p < 0.05). The clinical efficacy of treatment was reflected neither by a decrease of serum IgE nor by a decrease of elevated serum levels of soluble adhesion molecules sICAM-1 and sELAM-1 in the two dose groups. In contrast, a marked but not significant decrease of serum ECP could be observed in the 50 J/cm2 group only. We conclude from these and other published data that although 10 J/cm2 UV-A1 has a limited effect on patients with severe atopic eczema, higher doses are of higher efficiency in the treatment of this condition.
