A patient suffering from severe pemphigus vulgaris was treated using large-volume plasma exchange in combination with an immunosuppressive regimen. As some recent reports have shown evidence that polyclonal, polyspecific human IgG in high doses through the i.v. route (IGIV) protect target platelets in idiopathic thrombocytopenic purpura from attack by antiplatelet autoantibodies and/or immune complexes, we also administered IGIV to this pemphigus-vulgaris patient. In order to test the hypothesis that IGIV might protect in vitro-cultured human skin from acantholysis induced by pemphigus antibodies, studies with skin organ cultures were carried out using plasma from another pemphigus-vulgaris patient who had undergone plasma exchange. The preincubation of either the skin explants or the pemphigus plasma with various concentrations of IGIV (ranging from 0.15 to 15 mg/ml in the culture medium) did not prevent acantholysis induced by the pemphigus plasma nor did it inhibit the binding of the specific antibodies visualized by direct immunofluorescence. Thus, the assumption that IGIV may coat the pemphigus antigens on epidermal cells making them inaccessible to pathogenic autoantibodies was not substantiated by our tests in vitro; likewise, the hypothesis of functionally blocking autoantibody activity by means of anti-idiotype effects of IGIV cannot be supported.
