title: Cytokine profiles in pemphigus vulgaris patients treated with intravenous immunoglobulins as compared to conventional immunosuppressive therapy.
abstract: Pemphigus vulgaris (PV) is a potentially fatal blistering disease of the skin and mucous membranes, characterized by the presence of autoantibodies against adhesion molecules (desmoglein, Dsg3) present on the surface of keratinocytes, which lead to the loss of cellular adhesion or acantholysis. The mainstay of treatment is conventional immunosuppressive therapy (CIST), i.e. high dose, long-term systemic corticosteroids with or without immunosuppressive drugs. Intravenous immunoglobulin (IVIg) has been used in patients refractory to CIST, and its use has resulted in long-term clinical remission. Since cytokines play an important role in the immunopathogenesis of PV, it would be useful to compare how both IVIg and CIST therapies affect cytokine levels in the serum of PV patients. Thus, the goal of this study was to conduct a comparative analysis of levels of various cytokines, during an 18 month consecutive period, after the initiation of CIST or IVIg treatment in PV patients, with similar extent and severity of disease in the two study groups, with 11 patients in each group. The cytokines measured were IL-1beta, IL-6, IL-8, IFN-gamma, IL-4 and IL-10. The levels of most of these cytokines were higher in the sera of untreated patients in both groups, compared to normal controls. The cumulative data collected over an 18 month period of treatment demonstrates that there is a gradual reduction in the levels of these cytokines, until they are at levels observed in normal individuals. The conclusions from this limited number of patients, prospectively studied, would suggest that both CIST and IVIg therapies are similar in their ability to influence a panel of cytokines in patients with pemphigus vulgaris.
