| Abstract |
Purpose
: Atopic dermatitis is characterized by reduced IFN-γ production and increased IL-4 production. As a result, IgE production increases in atopic dermatitis. In the previous studies, it was reported that recombinant IFN-γ therapy is effective in treatment of severe atopic dermatitis. In this study, changes of plasma IFN-γ, IL-4, IL-5 and IL-10 concentration by IFN-γ therapy were studied in atopic dermatitis. Changes of plasma IgE levels and eosinophil counts were also investigated in the present report.
Methods
: Sixty-five atopic dermatitis patients were studied. Diagnostic criteria for atopic dermatitis were those used by Hanifin and Rajka. Patients received 2×106 units/m2 IFN-γ by subcutaneous injection eighteen times for six weeks. The following investigations were performed : complete blood cell count, total IgE, eosinophil percentage and total eosinophil count in addition to plasma IFN-γ, IL-4, IL-5 and IL-10 concentration.
Results
: Plasma concentrations of IL-4, IL-5 and IL-10 decreased by IFN-γ therapy in atopic dermatitis. However, plasma IFN-γ concentration was not changed. No significant correlations among the changes of IgE, eosinophil counts and plasma cytokine concentrations were detected.
Conclusion
: Plasma concentrations of Th2 cytokine such as IL-4, IL-5 and IL-10 decreased by IFN-γ therapy. This study suggests that Th2 cytokines might not be produced simulaneously. and that changes of Th2 cytokines might not affect the quantitiative changes of IgE and of eosinophil count. |
